To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris.A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment.There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P0.05). No obvious adverse reaction was found in either group.ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction.

The influence of peripheral muscle strength on prognosis after extubation and subsequent functional outcomes is not evident. The objectives of this study were to determine (1) whether peripheral muscle strength can be used as a predictor for patients’ prognoses after extubation, and (2) whether the peripheral muscle strength before extubation is correlated with patients’ subsequent ambulation ability and in-hospital mortality. This study was a prospective observational cohort study. A hand-held dynamometer was used for evaluated the muscle strength of the biceps and quadriceps right before extubation. Besides, after the patients had been transferred from the ICU to the general ward, a 2-minute walk test was performed. A total of 52 patients were enrolled in this study, and the rate of extubation failure was 15%. The muscle strength of the quadriceps was significantly correlated with the prognosis after extubation, 48% of the patients were able to ambulate after being transferred to the general ward. The overall mortality rate was 11%, and there was a significant correlation between the biceps muscle strength and in-hospital mortality. Peripheral muscle strength may serve as an important predictor of a patients’ prognoses after extubation. Poor peripheral muscle strength is indicative of not only a higher risk of re-intubation but also higher in-hospital mortality and poorer functional outcomes.Trial registration: ISRCTN16370134.

The aim was to investigate the feasibility and effects of an eight-week multimodal exercise program in sedentary postmenopausal women with urinary incontinence (UI) compared with pelvic floor muscle training (PFMT) only.This was a pilot randomized controlled trial. The participants were randomly allocated to either the intervention group (IG), who received a multimodal exercise program that incorporated aerobic exercise, resistance exercise, and PFMT, or the control group (CG), who received PFMT only. The intervention was provided twice weekly for eight weeks.The primary outcome was feasibility in relation to consent rate, attendance, withdrawal rate, satisfaction with program, and adverse events. The secondary outcomes included pelvic floor muscle function (assessed using digital palpation and manometry), UI-specific quality of life (QoL) (rated on the International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms Quality of Life [ICIQ-LUTSqol]), symptom severity (assessed using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI SF] and a bladder diary), and physical activity levels (rated on the International Physical Activity Questionnaire- short form [IPAQ]).Thirty-three of 63 eligible participants (52.4 %) consented to participate in the study and 26 completed it (IG n = 13, CG n = 13); the withdrawal rate was lower in the IG than in the CG (13.3 % vs 27.8 %). In both groups the attendance rate was 100 % and the satisfaction rate was 84.6 %. No adverse events were reported. The intention-to-treat analysis showed that UI-specific QoL (p = 0.011, mean difference: -5.62, 95 % CI: -9.67 to -1.57) and symptom severity measured using the ICIQ-UI SF (p = 0.001, mean difference: -3.23, 95 % CI: -4.93 to -1.54) were significantly improved in the IG after intervention, while no significant changes were found in the CG after intervention. The daytime frequency (p = 0.001) and number of leakages (p = 0.045) recorded in the bladder diary were significantly reduced in the CG after intervention. No significant differences between groups were found on any of the outcome measurements after intervention, except the daytime frequency from the bladder diary, which was significantly more reduced in the CG than in the IG (p = 0.003, mean difference: -0.28, 95 % CI: -2.25 to 1.67).An eight-week multimodal exercise program is feasible for sedentary postmenopausal women with UI, and the multimodal exercise program demonstrated potential benefits for improving UI-specific QoL and symptom severity in this population. The trial was registered at ClinicalTrials.gov (NCT04351750).

STUDY OBJECTIVES: We aimed (1) to investigate the effect of a 12-week exercise training on sleep quality and heart rate variability in middle-aged and older adults with poor sleep quality and (2) to examine the factors associated with the improvements in sleep quality and heart rate variability parameters. METHODS: Forty adults aged ≥ 40 years with poor sleep quality (mean age = 62 years; 82.5% female) participated in this study. They were randomized into the exercise group or control group. Each exercise training program consisted of 40 minutes of supervised aerobic exercise training and 10 minutes of stretching class, 3 times a week for 12 weeks. Outcome measures included both subjective (Pittsburgh Sleep Quality Index) and objective (actigraphy recordings) sleep quality assessments, a cardiopulmonary exercise test, and heart rate variability assessment. RESULTS: The exercise group showed significant improvements in the global score (P = .003), on all subscales of Pittsburgh Sleep Quality Index (P < .05), and in some heart rate variability parameters compared to the control group. Multiple regression analysis indicated that exercise participation was associated with either the sleep quality (β = −0.617, R(2) = .407; F = 6.226, P < .001) or heart rate monitor high frequency normalized units (β = 0.503, R(2) = .225; F = 3.200, P = .003) after adjustment for basic characteristics. However, the statistical significance between exercise participation and heart rate monitor high frequency normalized units diminished after controlling for the Pittsburgh Sleep Quality Index. CONCLUSIONS: Our results indicated that moderate-intensity exercise training had a beneficial effect on sleep quality and cardiac autonomic function. Middle-aged and older adults with poor sleep quality should be encouraged to engage in a moderate-intensity aerobic exercise training to improve their sleep quality and cardiac autonomic function.

Background Echinococcosis, a zoonotic parasitic disease, is caused by larval stages of cestodes in the Echinococcus genus. Echinococcosis is highly prevalent in ten provinces/autonomous regions of western and northern China. In 2016, an epidemiological survey of Tibet Autonomous Region (TAR) revealed that the prevalence of human echinococcosis was 1.66%, which was much higher than the average prevalence in China (0.24%). Therefore, to improve on the current prevention and control measures, it is important to understand the prevalence and spatial distribution characteristics of human echinococcosis at the township level in TAR. Methods Data for echinococcosis cases in 2018 were obtained from the annual report system of echinococcosis of Tibet Center for Disease Control and Prevention. Diagnosis had been performed via B-ultrasonography. The epidemic status of echinococcosis in all townships in TAR was classified according to the relevant standards of population prevalence indices as defined in the national technical plan for echinococcosis control. Spatial scan statistics were performed to establish the geographical townships that were most at risk of echinococcosis. Results In 2018, a total of 16,009 echinococcosis cases, whose prevalence was 0.53%, were recorded in 74 endemic counties in TAR. Based on the order of the epidemic degree, all the 692 townships were classified from high to low degrees. Among them, 127 townships had prevalence rates ≥ 1%. The high prevalence of human echinococcosis in TAR, which is associated with a wide geographic distribution, is a medical concern. Approximately 94.65% of the villages and towns reported echinococcosis cases. According to spatial distribution analysis, the prevalence of human echinococcosis was found to be clustered, with the specific clustering areas being identified. The cystic echinococcosis primary cluster covered 88 townships, while that of alveolar echinococcosis’s covered 38 townships. Conclusions This study shows spatial distributions of echinococcosis with different epidemic degrees in 692 townships of TAR and high-risk cluster areas at the township level. Our findings indicate that strengthening the echinococcosis prevention and control strategies in TAR should directed at townships with a high prevalence and high-risk clustering areas.

Soil antimony (Sb) contamination occurs globally due to natural processes and human activities. Total Sb concentration in soils fails to assess its ecological risk, while determined by the concentration of available Sb, which is readily for biological uptake. Available Sb in different soils varied significantly according to soil properties. However, so far it is unknown how soil properties regulate Sb availability, and no model has been established to predict it through soil properties. In this study, 19 soils spiked with antimonite [Sb(III)] were used to identify the major factors controlling Sb availability and establish its predicting models. The results showed that available Sb in different soils varied largely depending on the contents of free aluminum (fAl), free iron (fFe) and electric conductivity (EC), which explained 33%, 27% and 24.9% of the total variation, respectively. During the first 42 days of soil aging, fAl and EC effectively predicted the concentrations of available Sb with R

Background Echinococcosis is a zoonotic parasitic disease caused by larval stages of cestodes belonging to the genus Echinococcus. The infection affects people’s health and safety as well as agropastoral sector. In China, human echinococcosis is a major public health burden, especially in western China. Echinococcosis affects people health as well as agricultural and pastoral economy. Therefore, it is important to understand the prevalence status and spatial distribution of human echinococcosis in order to advance our knowledge of basic information for prevention and control measures reinforcement. Methods Report data on echinococcosis were collected in 370 counties in China in 2018 and were used to assess prevalence and spatial distribution. SPSS 21.0 was used to obtain the prevalence rate for CE and AE. For statistical analyses and mapping, all data were processed using SPSS 21.0 and ArcGIS 10.4, respectively. Chi-square test and Exact probability method were used to assess spatial autocorrelation and spatial clustering. Results A total of 47,278 cases of echinococcosis were recorded in 2018 in 370 endemic counties in China. The prevalence rate of human echinococcosis was 10.57 per 10,000. Analysis of the disease prevalence showed obvious spatial positive autocorrelation in globle spatial autocorrelation with two aggregation modes in local spatial autocorrelation, namely high-high and low-high aggregation areas. The high-high gathering areas were mainly concentrated in northern Tibet, western Qinghai, and Ganzi in the Tibetan Autonomous Region and in Sichuan. The low-high clusters were concentrated in Gamba, Kangma and Yadong counties of Tibet. In addition, spatial scanning analysis revealed two spatial clusters. One type of spatial clusters included 71 counties in Tibet Autonomous Region, 22 counties in Qinghai, 11 counties in Sichuan, three counties in Xinjiang Uygur Autonomous Region, two counties in Yunnan, and one county in Gansu. In the second category, six types of spatial clusters were observed in the counties of Xinjiang Uygur Autonomous Region, and the Qinghai, Gansu, and Sichuan Provinces. Conclusion This study showed a serious prevalence of human echinococcosis with obvious spatial aggregation of the disease prevalence in China. The Qinghai-Tibet Plateau is the "hot spot" area of human echinococcosis in China. Findings from this study indicate that there is an urgent need of joint strategies to strengthen efforts for the prevention and control of echinococcosis in China, especially in the Qinghai-Tibet Plateau., Author summary Echinococcosis is a zoonotic parasitic disease caused by larval stages of cestodes belonging to the genus Echinococcus.

Background The echinococcosis is prevalent in 10 provinces /autonomous region in western and northern China. Epidemiological survey of echinococcosis in China in 2012 showed the average prevalence of four counties in Tibet Autonomous Region (TAR) is 4.23%, much higher than the average prevalence in China (0.24%). It is important to understand the transmission risks and the prevalence of echinococcosis in human and animals in TAR. Methods A stratified and proportionate sampling method was used to select samples in TAR. The selected residents were examined by B-ultrasonography diagnostic, and the faeces of dogs were tested for the canine coproantigen against Echinococcus spp. using enzyme-linked immunosorbent assay. The internal organs of slaughtered domestic animals were examined by visual examination and palpation. The awareness of the prevention and control of echinococcosis among of residents and students was investigated using questionnaire. All data were inputted using double entry in the Epi Info database, with error correction by double-entry comparison, the statistical analysis of all data was processed using SPSS 21.0, and the map was mapped using ArcGIS 10.1, the data was tested by Chi-square test and Cochran-Armitage trend test. Results A total of 80 384 people, 7564 faeces of dogs, and 2103 internal organs of slaughtered domestic animals were examined. The prevalence of echinococcosis in humans in TAR was 1.66%, the positive rate in females (1.92%) was significantly higher than that in males (1.41%), (χ2 = 30.31, P

The development of low-frequency ultrasound imaging technology and the improvement of ultrasound contrast agent production technology mean that they play an increasingly important role in tumor therapy. The interaction between ultrasound and microbubbles and their biological effects can transfer and release microbubbles carrying genes and drugs to target tissues, mediate the apoptosis of tumor cells, and block the embolization of tumor microvasculature. With the optimization of ultrasound parameters, the development of targeted microbubbles, and the emergence of various composite probes with both diagnostic and therapeutic functions, low-frequency ultrasound combined with microbubble contrast agents will bring new hope for clinical tumor treatment.

Background Echinococcosis is a global zoonotic parasitic disease caused by Echinococcus larvae. This disease is highly endemic in Sichuan Province, China. This study investigates the prevalence and spatial distribution characteristics of human echinococcosis at the township level in Sichuan Province, geared towards providing a future reference for the development of precise prevention and control strategies. Methods Human prevalence of echinococcosis was evaluated using the B-ultrasonography diagnostic method in Sichuan Province between 2016 and 2019. All data were collected, collated, and analyzed. A spatial distribution map was drawn to intuitively analyze the spatial distribution features. Eventually, the spatial autocorrelation was specified and local indicators of spatial association (LISA) clustering map was drawn to investigate the spatial aggregation of echinococcosis at the township level in Sichuan Province. Results The prevalence of echinococcosis in humans of Sichuan Province was 0.462%, among which the occurrence of cystic echinococcosis (CE) was 0.221%, while that of alveolar echinococcosis (AE) was 0.244%. Based on the results of the spatial distribution map, a predominance of echinococcosis in humans decreased gradually from west to east and from north to south. The Global Moran’s I index was 0.77 (Z = 32.07, P Conclusions Our findings demonstrated that the prevalence of echinococcosis in humans of Sichuan Province follows a downward trend, suggesting that the current prevention and control work has achieved substantial outcomes. Nevertheless, the prevalence in humans at the township level is widely distributed and differs significantly, with a clear clustering in space. Therefore, precise prevention and control strategies should be formulated for clusters, specifically strengthening the “high–high” clusters at the township level. Graphic Abstract

Background and objectives The main target of inspiratory muscle training (IMT) is to improve diaphragm function in patients with COPD who have inspiratory muscle weakness. Ventilatory demand is already increased during quiet breathing in patients with COPD, and whether threshold load imposed by IMT would active more accessory muscle remained to be determined. The purpose of this study was to examine diaphragm and sternocleidomastoid (SCM) activation during IMT with intensities of 30% and 50% maximal inspiratory pressure (PImax). Methods Patients with COPD and a PImax lower than 60 cmH2O were recruited for the study. Surface electromyography (EMG) was used to measure diaphragm and SCM activation, and group-based trajectory modeling (GBTM) was used to identify activation patterns during IMT. The generalized estimating equation (GEE) was then used to detect differences of variables between various breathing tasks. Statistical significance was established at p Results A total of 30 patients with COPD participated in this study. All patients demonstrated significant increases in diaphragm and SCM activation during 30% and 50% PImax of IMT than during quiet breathing (all p Conclusion Diaphragm and SCM were substantially activated during IMT in patients with COPD who had inspiratory muscle weakness. Regardless of whether diaphragm activation was high or low, SCM was activated to a greater extent in response to IMT.

Background The intrathecal hyperbaric bupivacaine dosage for cesarean section is difficult to predetermine. This study aimed to develop a decision-support model using a machine-learning algorithm for assessing intrathecal hyperbaric bupivacaine dose based on physical variables during cesarean section. Methods Term parturients presenting for elective cesarean section under spinal anaesthesia were enrolled. Spinal anesthesia was performed at the L3/4 interspace with 0.5% hyperbaric bupivacaine at dosages determined by the anesthesiologist. A spinal spread level between T4-T6 was considered the appropriate block level. We used a machine-learning algorithm to identify relevant parameters. The dataset was split into derivation (80%) and validation (20%) cohorts. A decision-support model was developed for obtaining the regression equation between optimized intrathecal 0.5% hyperbaric bupivacaine volume and physical variables. Results A total of 684 parturients were included, of whom 516 (75.44%) and 168 (24.56%) had block levels between T4 and T6, and less than T6 or higher than T4, respectively. The appropriate block level rate was 75.44%, with the mean bupivacaine volume [1.965, 95%CI (1.945,1.984)]ml. In lasso regression, based on the principle of predicting a reasonable dose of intrathecal bupivacaine with fewer physical variables, the model is “Y=0.5922+ 0.055117* X1-0.017599*X2” (Y: bupivacaine volume; X1: vertebral column length; X2: abdominal girth), with λ 0.055, MSE 0.0087, and R2 0.807. Conclusions After applying a machine-learning algorithm, we developed a decision model with R2 0.8070 and MSE due to error 0.0087 using abdominal girth and vertebral column length for predicting the optimized intrathecal 0.5% hyperbaric bupivacaine dosage during term cesarean sections.

Background Echinococcosis is highly endemic in western and northern China. Tibet Autonomous Region (TAR) is the most serious prevalent area. Linzhi is located in southeastern part of TAR. Dogs are the primary infection source for the transmission of echinococcosis to humans. A control and prevention campaign based on dog management has been implemented in the past three years. This study aims to evaluate the effects of dog management on the infection rate of dogs. Methods Data of dog population, registration and de-worming of seven counties/district in Linzhi between 2017 and 2019 were obtained from the annual prevention and control report. Domestic dog fecal samples were collected from each endemic town of seven counties/district in Linzhi in 2019 to determine the infection of domestic dogs using coproantigen enzyme-linked immunosorbent assay (ELISA). Data analysis was processed using SPSS statistics to compare dog infection rate between 2016 and 2019 by chi-square test, and maps were mapped using ArcGIS. Results In Linzhi, domestic dog population has decreased from 17 407 in 2017 to 12 663 in 2019, while the registration rate has increased from 75.9% in 2017 to 98.6% in 2019. Similarly, stray dog population has decreased from 14 336 in 2017 to 11 837 in 2019, while sheltered rate has increased from 84.6% in 2017 to 96.6% in 2019. Dog de-worming frequency has increased from 4 times per annum in 2017 to 12 times in 2019, indicating that approximately every dog was dewormed monthly. A total of 2715 dog fecal samples were collected for coproantigen ELISA assay. The dog infection rate was 2.8% (77/2715) in 2019, which was significantly lower than 7.3% (45/618) in 2016 (P Conclusions Increased dog registration, decreased dog population, and increased dog de-worming frequency contributed to significantly decrease the dog infection rate in Linzhi. Control and prevention campaign based on dog management could significantly decrease dog infection with Echinococcus spp. in echinococcosis endemic areas.

Berberine is the main extract of Coptis chinensis, and its anti-inflammatory, antioxidant, antibacterial and immunomodulatory effects have been confirmed by modern studies. Ulcerative colitis(UC) is a chronic, idiopathic inflammatory bowel disease with unknown etiology. Its causes involve genetics, intestinal microecology and mucosal immune system disorders. In this paper, literatures on relevant pathways and mechanism of berberine on ulcerative colitis in recent years were consulted and summarized to provide me-thods and ideas for developing berberine in the treatment of UC and exploring the mechanisms. The results showed that berberine protects the intestinal mucosal barrier, restores the body's normal immune response, and improves oxidative stress by regulating multiple signaling pathways, such as JAK-STAT, NK-κB, PI3 K-AKT, MAPK, Nrf2, ERS, and MLCK-MLC, so as to treat UC.

Human echinococcosis is present worldwide but it is in China that disease prevalence is the highest. In western China, especially in the Tibetan Plateau, the burden of echinococcosis is the most important. Dogs are a major definitive host of Echinococcus and monitoring the presence of Echinococcus worms in dogs is therefore essential to efficiently control the disease. Detection kits based on three different technologies including sandwich ELISA, (indirect) ELISA, and gold immunodiffusion, are currently marketed and used in China. The objective of this work was to assess the efficacy of these kits, in particular with respect to sensitivity and specificity. Four fecal antigen detection kits for canine infection reflecting the three technologies were obtained from companies and tested in parallel on 220 fecal samples. The results indicate that the performance is lower than expected, in particular in terms of sensitivity. The best results were obtained with the sandwich ELISA technology. The gold immunofiltration yielded the poorest results. In all cases, further development is needed to improve the performance of these kits which are key components for the control of echinococcosis., Author summary Although present worldwide, human echinococcosis is at its highest prevalence in western China and particularly in the Tibetan Plateau. Controlling echinococcosis is a national priority and routine monitoring must be established. Dogs are the main infection source in China and surveying Echinococcus worms in dogs is therefore a research priority. Commercial detection kits are currently in use in China to monitor the presence of Echinococcus in dogs. The kits are based on three different technologies including sandwich ELISA with two monoclonal antibodies, (indirect) ELISA, and gold immunodiffusion. National survey programmes are essential for the control of echinococcosis and it is thus very important to assess the efficacy of these kits for the programmes. This work was therefore undertaken to assess efficacy of the kits, in particular with respect to sensitivity and specificity. Four fecal antigen detection kits for canine infection reflecting the three technologies were obtained from companies and tested in parallel on 220 fecal samples. The performance was lower than expected, in particular for their sensitivity which ranged between 51.5% and 83.9% with only two samples displaying a worm burden lower than 100. Three out of four kits showed non-specific cross-reactions with other parasites. The best results were obtained with the sandwich ELISA technology, whereas gold immunofiltration yielded the poorest results. However, in all cases, further development is strongly needed to improve the performance of these kits which are key components for the control of echinococcosis.

To evaluate the effect and mechanism of radiotherapy (RT)–sorafenib pharmacokinetics (PK) in different regimens with conventional or high dose irradiation. Between February 2012 and December 2018, 43 patients with portal vein tumor thrombosis treated with sorafenib plus conventional RT (58%) or stereotactic body radiation therapy (SBRT, 42%) were retrospectively reviewed. In vivo and in vitro studies of concurrent and sequential RT with sorafenib were designed. SBRT resulted in a 3-fold increase in complete recanalization compared to conventional RT group (28% vs. 8%, p = 0.014). Compared to the control group, the area under the concentration vs. time curve (AUC) of sorafenib was increased in the concurrent RT2Gy and RT9Gy groups and the sequential RT9Gy group by 132% (p = 0.046), 163% (p = 0.038) and 102% (p = 0.018), respectively; and was decreased by 59% in the sequential RT2Gy group (p = 0.036). Sequential RT2Gy and RT9Gy increased CYP3A4 activity by 82% (p = 0.028) and 203% (p = 0.0004), respectively, compared to that with the corresponding concurrent regimen. SBRT produced better recanalization than conventional RT with sorafenib. The AUC of sorafenib was modulated by RT. P-gp expression was not influenced by RT. The sequential RT regimen increased CYP3A4 activity that may increase the RT-sorafenib synergy effect and overall sorafenib activity. The biodistribution of sorafenib was modulated by local RT with the different regimens.

Background We designed the current study to understand the normal trajectories of interleukin-6 (IL-6) and C-reactive protein (CRP) in the immediate hours and days after primary total knee arthroplasty (TKA) under the management of an enhanced recovery after surgery (ERAS) protocol and examined whether one or the other returned to normal more quickly. Methods In this prospective cross-sectional study, we examined the plasma IL-6 and CRP levels in 100 patients undergoing primary TKA at the following time points: 12 h preoperatively as well as postoperatively 12 h, 48 h, 3 days and 2 weeks. Patients were followed up for 1 year to monitor the postoperative complications, especially the infection. Results IL-6 peaked at 48 h postoperatively. Then IL-6 started to decline at 3 days postoperatively and went back to baseline level at 2 weeks (p = 0.950). CRP peaked at 3 days postoperatively. At 2 weeks, CRP declined to a normal range, without being significantly different from the baseline level (p = 0.816). Conclusion We found that under the ERAS scenario, the postoperative peak of IL-6 and CRP was deferred compared with previous studies. Compared to IL-6, CRP showed a gradual rise after surgery. Both of these two biomarkers returned to normal under the ERAS scenario. Future multiple-center studies with larger sample size can help define the thresholds of IL-6 and CRP for periprosthetic joint infection (PJI) early diagnosis. With these reference data, a clinician can make a quicker decision to perform aspiration to diagnose early PJI and benefits more patients.

The long circulating half-life and inherently bivalent architecture of IgGs provide an ideal vehicle for presenting otherwise short-lived G-protein-coupled receptor agonists in a format that enables avidity-driven enhancement of potency. Here, we describe the site-specific conjugation of a dual agonist peptide (an oxyntomodulin variant engineered for potency and in vivo stability) to the complementarity-determining regions (CDRs) of an immunologically silent IgG4. A cysteine-containing heavy chain CDR3 variant was identified that provided clean conjugation to a bromoacetylated peptide without interference from any of the endogenous mAb cysteine residues. The resulting mAb-peptide homodimer has high potency at both target receptors (glucagon receptor, GCGR, and glucagon-like peptide 1 receptor, GLP-1R) driven by an increase in receptor avidity provided by the spatially defined presentation of the peptides. Interestingly, the avidity effects are different at the two target receptors. A single dose of the long-acting peptide conjugate robustly inhibited food intake and decreased body weight in insulin resistant diet-induced obese mice, in addition to ameliorating glucose intolerance. Inhibition of food intake and decrease in body weight was also seen in overweight cynomolgus monkeys. The weight loss resulting from dosing with the bivalently conjugated dual agonist was significantly greater than for the monomeric analog, clearly demonstrating translation of the measured in vitro avidity to in vivo pharmacology.

The metastatic potential of malignant tumor has been shown to be correlated with the increased expression of tri- and tetra-antennary β1,6-N-acetylglucosamine (β1,6-GlcNAc) N-glycans. In this study, We found that GnT-V expression was negatively correlated with receptor protein tyrosine phosphatase type μ(RPTPμ) in human glioma tissues. To study whether RPTPμ is a novel substance of GnT-V which further affect RPTPμ′s downstream dephosphorylation function, we preform lentiviral infection with GnT-V gene to construct stably transfected GnT-V glial cell lines. We found RPTPμ undergone severer cleavage in GnT-V transfected glioma cells compare to Mock cells. RPTPμ intracellular domain fragments increased while β1,6-GlcNAc-branched N-glycans increased, in consistent with the decrease of RPTPμ′s catalytic activity. The results showed that abnormal glycosylation could decrease the phosphorylation activity of PTP μ, and affect PLCγ-PKC pathways. Both protease inhibitor Furin and N-glycan biosynthesis inhibitor swainsonine could decrease cell mobility in GnT-V-U87 transfectants and other glioma cell lines. All results above suggest increased post-translational modification of RPTPμ N-glycans by GnT-V attenuates its tyrosine phosphatase activity and promotes glioma cell migration through PLCγ-PKC pathways, and that the β1,6-GlcNAc-branched N-glycans of RPTPμ play a crucial role in glioma invasivity.

Nausea and vomiting are among the most common and distressing side effects of chemotherapy. Additional antiemetic drugs are urgently needed to effectively manage and ameliorate chemotherapy-induced nausea and vomiting (CINV). The efficacy of ginger as an antiemetic modality for ameliorating CINV has not been established in previous studies. The aim of this study was to examine the efficacy of ginger, as an adjuvant drug to standard antiemetic therapy, in ameliorating acute and delayed CINV in patients with lung cancer receiving cisplatin-based regimens. In this randomized, double-blind, placebo-controlled clinical trial, 140 patients with lung cancer receiving cisplatin-based regimens were enrolled and allocated to receive either ginger root powder or a placebo. Ginger root powder was administered orally (0.5 g, 2 capsules per day, 0.25 g per capsule, every 12 hours) for 5 days beginning on the first day of chemotherapy. The incidence and severity of acute and delayed nausea and vomiting were assessed using the MASCC (Multinational Association for Supportive Care in Cancer) Antiemesis Tool (MAT). Adverse effects and patient adherence were also assessed in this study. No significant difference was observed between the ginger and control groups in the reduction of the incidence and severity of nausea and vomiting ( P > .05). No significant difference in adverse events was observed between the 2 groups ( P > .05). No study-treatment-related adverse events were observed in this study. As an adjuvant drug to standard antiemetic therapy, ginger had no additional efficacy in ameliorating CINV in patients with lung cancer receiving cisplatin-based regimens.

Purpose: Concurrent chemoradiation therapy is the mainstay of treatment for many types of malignancies. However, concurrent chemoradiation therapy is associated with a greater number of systemic adverse effects than radiotherapy or chemotherapy alone. Summary: Pharmacokinetics is the study of a drug and/or its metabolite kinetics in the body, including absorption, distribution, metabolism, and elimination. The incidences of adverse effects are markedly higher in patients who receive concurrent chemoradiation therapy than in those who receive either radiotherapy or chemotherapy alone. This phenomenon implies that irradiation affects the pharmacokinetics of cytotoxic agents, namely the radiotherapy–pharmacokinetic phenomenon. Experimental animal studies have shown that local irradiation affects the systemic pharmacokinetics of 5-fluorouracil and cisplatin at both low dose (simulating generous dose distributed to normal tissues) and daily practice dose (mimicking therapeutic dose to target volumes). These effects are significant in the circulation of blood and lymphatic system as well as in the hepatobiliary excretion. Furthermore, recent studies have demonstrated that matrix metalloproteinase-8 plays an important role in the radiotherapy–pharmacokinetic phenomenon. Conclusion: In the present review, we provide a general overview of the radiotherapy–pharmacokinetic phenomenon and discuss the possible mechanisms governing the phenomenon.

Receptor-like protein tyrosine phosphatase alpha (RPTPα or PTPα), a type I transmembrane glycoprotein with complex N-glycans, executes multifunction roles on cell behaviors. However, its effect on tumorigenesis and metastasis remains controversial. In this study, PTPα is identified as a novel substrate of N-Acetylglucosaminyltransferase V (GnT-V). Immunofluorescence results showed that addition of β1,6 GlcNAc branches on PTPα enhanced PTPα's cytomembrane assemble in GnT-V-MCF-7 compared with Mock-MCF-7 (MCF7 cells transfected with the vector pcDNA3). Then we found the alleviating degradation of PTPα was observed in GnT-V-MCF-7 while PTPα in Mock-MCF-7 was prone to quick degradation. Increased cell-surface retention subsequently enhanced PTPα's catalytic activity on the dephosphorylation of Src kinase at Tyr529 and promoted focal adhesion formation and mature. Therefore, our findings could provide an insight into the molecular mechanism of how GnT-V promoted cell migration, suggesting that PTPα could be one of factors regulating promote migration of breast cancer cell.

Echinococcosis is a serious zoonotic parasitic disease that is highly endemic in Qinghai Province. The present study aimed to investigate the prevalence of echinococcosis among schoolchildren in Golog Tibetan Autonomous Prefecture to improve early diagnosis and treatment of patients and to provide information for echinococcosis prevention and control. A total of 11,260 schoolchildren from five counties (Maqin, Gander, Dari, Jiuzhi, and Banma) in Golog Tibetan Autonomous Prefecture, Qinghai Province, were screened for echinococcosis. Screening involved ultrasound imaging combined with serologic examination as an auxiliary diagnostic test. The prevalence of echinococcosis in the schoolchildren was 2.1% (235/11,260), with a rate of 0.8% for cystic echinococcosis (CE; 89/11,260) and 1.3% for alveolar echinococcosis (AE; 146/11,260). Additionally, one child had a mixed infection. The prevalence ranged between 1.1% and 4.1% among the five investigated counties, and was highest in Dari County (4.1%). The prevalence of echinococcosis was higher in girls than in boys and gradually increased with age. In addition, children with CE mainly had type 1 (CE1) and type 3 (CE3) lesions, and children with AE mainly had small-diameter calcified lesions, suggesting that they were in the early asymptomatic stage of echinococcosis. In conclusion, children of Golog Tibetan Autonomous Prefecture appear to exhibit the highest recorded prevalence of CE and AE globally. Ultrasound is useful for screening populations in regions where both CE and AE are endemic.

Type 1 diabetes mellitus (T1DM) is associated with an increased risk of diabetic cardiomyopathy (DCM). Nuclear factor kappa B (NF-κB) and Wnt/β-catenin/GSK3β have been demonstrated to play pathogenic roles in diabetes. In this study, we evaluated the roles of these two pathways in T1DM-induced cardiomyopathy in rats. Streptozotocin (STZ)-induced type 1 diabetic rats were treated with pyrrolidine dithiocarbamate (PDTC) or meisoindigo (Me) to inhibit NF-κB and Wnt/β-catenm/GSK3β respectively for 4 or 8 weeks. As compared with untreated diabetic rats, treatment with either PDTC or Me partly attenuated the myocardial hypertrophy and interstitial fibrosis, improved cardiac function, and exhibited reduction in inflammatory reaction. In addition, we found that inhibiting NF-κB and Wnt/β-catenin/GSK3β pathways could regulate glucose and lipid metabolism. The effects were associated with the decrease of NF-κB activity and the downregulation of some proinflammatory cytokines, including tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-2. Our data suggested that the activities of NF-κB and Wnt/β-catenin/GSK3β pathways were both increased and inhibiting NF-κB and Wnt/β-catenin/GSK3β signaling pathways might improve myocardial injury in T1DM rats.

Background: Pulmonary rehabilitation (PR) is now considered fundamental when managing patients with chronic respiratory disease. The individual variation in functional exercise capacity (FEC) response to PR within the cohort is unknown. The purpose of this study was to identify FEC patterns in response to PR in patients with chronic respiratory disease using the trajectory modeling method. Methods: The data of 67 patients with the chronic respiratory disease were retrospectively reviewed and analyzed in this study. All patients received once-weekly supervised training for 8 weeks. Six-minute walk distance (6MWD) was used to measure FEC. Muscle strength and 6MWD were assessed at baseline, Week 4, Week 8 and monthly for two months after PR completion. Group-based trajectory modeling (GBTM) was used to identify patterns in 6MWD in response to PR. The generalized estimating equation method was then used to detect the differences within and between the trajectories of identified groups across time. Results: Patients were grouped into low- (n=13), moderate- (n=34) and high- (n=20) FEC group based on GBTM analysis. All groups demonstrated significant improvements in 6MWD and leg muscle strength after 8-week PR. Compared to the high-FEC group, a greater proportion of the patients in the low-FEC group required oxygen supplementation during training and had worse baseline leg muscle strength. Conclusions: Patients showed distinct patterns of 6MWD changes in response to 8-week PR. Distinct characteristics for the low-FEC group included poor lower extremity strength and a greater proportion of required oxygen use at home and during training., Video abstract Point your SmartPhone at the code above.

Background Helical irradiation of the total skin (HITS) was modified as simultaneous integrated boost (SIB)-helical arc radiotherapy of total skin (HEARTS) technique and applied to an acute myeloid leukemia (AML) patient with disseminated leukemia cutis. Methods The original HITS plan was revised for different regimens, i.e. HEARTS, low-dose HEARTS and SIB-HEARTS. The uniformity index (UI), conformity index (CI), and dose of organs at risk (OARs) were used to evaluate the plans. Additionally, the SIB-HEART (21/15 Gy) was delivered to the total skin and chloromas. Results No significant differences were observed for the CI and UI between HITS and HEARTS regimens. Compared with HITS, the reduced mean doses to various bone marrows ranged from 17 to 88%. The mean OARs doses for the head, chest and abdomen of a patient with AML treated with SIB-HEARTS (21/15 Gy) were 2.1 to 21.9 Gy, 1.8 to 7.8 Gy and 1.7 to 3.3 Gy, respectively. No severe adverse effects were noted except for grade 4 leukocytopenia and thrombocytopenia. Conclusion HEARTS and different regimens reduced the dose to OARs and bone marrow while maintaining the uniformity and conformity. SIB-HEARTS deliveries different doses to the total skin and enlarged tumors simultaneously. Trial registration Retrospectively registered and approved by the Institutional Review Board of our hospital (FEMH-106151-C).

Background: Diabetes mellitus (DM) remains a major health problem worldwide. Several clinical trials have shown the superiority of the Traditional Chinese Medicine in delaying or reversing the development and progression of DM. This study aimed to evaluate the efficacy of Jinlida (JLD) granule, a Chinese herbal recipe, in the treatment of impaired glucose tolerance (IGT) and its effect on the prevention of DM. Methods: Sixty-five IGT patients were randomized to receive one bag of JLD granules three times daily (JLD group, n = 34) or no drug intervention (control group, n = 31) for 12 weeks. Oral glucose tolerance test, glycated hemoglobin A1c (HbA1c), body mass index, blood lipids levels, fasting insulin, and insulin resistance calculated using homeostatic model assessment (HOMA-IR) of all the patients were observed and compared before and after the treatment. Results: Sixty-one participants completed the trial (32 in JLD group and 29 in the control group). There were statistically significant decreases in HbA1c (P < 0.001), 2-h plasma glucose (P < 0.001), and HOMA-IR (P = 0.029) in JLD group compared with the control group after 12 weeks of treatment. After 12 weeks of treatment, two (6.9%) patients returned to normal blood glucose, and five (17.2%) patients turned into DM in control group, while in the JLD group, 14 (43.8%) returned to normal blood glucose and 2 (6.2%) turned into DM. There was a significant difference in the number of subjects who had normal glucose at the end of the study between two groups (P = 0.001). Conclusions: JLD granule effectively improved glucose control, increased the conversion of IGT to normal glucose, and improved the insulin resistance in patients with IGT. This Chinese herbal medicine may have a clinical value for IGT.

This study aimed to review clinical experiences using whole-field simultaneous integrated boost (SIB) intensity-modulated radiotherapy (IMRT) and sequential IMRT in postoperative patients with oral cavity cancer (OCC). From November 2006 to December 2014, a total of 182 postoperative patients with OCC who underwent either SIB-IMRT (n = 63) or sequential IMRT (n = 119) were enrolled retrospectively and matched randomly according to multiple risk factors by a computer. The differences were well balanced after patient matching ( P = .38). The median follow-up time was 65 months. For patients treated with the SIB technique and the sequential technique, the respective mortality rates were 36.8% and 20.0% ( P = .04). The primary recurrence rates were 26.3% and 10.0% ( P = .02), respectively. The respective marginal failure rates were 26.7% and 16.7%. A multivariate logistic regression analysis showed that patients who received the SIB technique had a 2.74 times higher risk of death than those who received the sequential technique (95% confidence interval = 1.10-6.79, P = .03). Sequential IMRT provided a significantly lower dose to the esophagus (5.2 Gy, P = .02) and trachea (4.6 Gy, P = .03) than SIB-IMRT. For patients with locally advanced OCC, postoperative sequential IMRT may overcome an unpredictable geographic miss, potentially with a lower marginal failure rate in the primary area. Patients treated by sequential IMRT show equal overall survival benefits to those treated by SIB-IMRT and a lower mortality rate than those treated by SIB-IMRT. Additionally, a reduced dose to the esophagus and trachea compared to sequential IMRT was noted.

Background Leishmania parasites cause visceral leishmaniasis (VL), an important infectious disease that is endemic to large parts of the world and often leads to epidemics. Sand flies are the primary transmission vector for the parasite in endemic regions. We hypothesized that sheep might serve as an overlooked reservoir for Leishmania transmission to humans due to the asymptomatic nature of infection in many species. As a preliminary test of this hypothesis, the aim of the present study was to investigate sheep in an area of China that is endemic for the desert sub-type of zoonotic VL and establish if they are potential carriers of Leishmania. Results Sheep tissue samples were collected from abattoirs in VL endemic areas of Jiashi County, China during the non-transmission season. rK39 immunochromatographic tests were performed to detect the presence of the parasite in blood samples. In addition, DNA was extracted from the blood, and used for detection of the Leishmania-specific internal transcribed spacer-1 (ITS-1) genomic region using a nested polymerase chain reaction (PCR) approach. PCR products were further analyzed to identify restriction fragment-length polymorphism patterns and representative sequences of each pattern were selected for phylogenetic analysis. The rK-39 and nested PCR data indicated positive detection rates for Leishmania in sheep of 26.32 and 54.39%, respectively. The phylogenetic analysis revealed that all of the samples belonged to the species L. infantum and were closely related to strains isolated from human infections in the same area. Conclusions Sheep could be a potential host for Leishmania in VL endemic areas in China and may be an overlooked reservoir of human VL transmission in this region. To further confirm livestock as a potential host, further verification is required using a sand fly biting experiment.

This study aimed to assess the competency of health professionals on helminthiasis control in China. The assessment system comprised of two parts, one being the parasitological knowledge test and the other a technical skills assessment. The knowledge test mainly examined morphology, epidemiology, life history and diagnosis of common and important parasites. The skills assessment consisted of sample slides making and species identification using microscopy. From 2012 to 2016, a total of 616 participants from different levels of parasitic diseases prevention and control departments of CDC took part in the assessment. The results had shown a high level of academic knowledge among participants. Accuracy rates of schistosomiasis, echinococcosis, food-borne helminthiases, and soil-transmitted helminthiasis were all above 60%. This showed an excellent knowledge level of helminthiases by participants. However, among all 616 participants, 94.97% passed the thick-smear passing test (>= 60%), while in microscopy tests the equivalent was only 43.67%. Competencies in different districts varied. It is imperative to set up a North-South skill exchange mechanism of helminthiases diagnostic techniques and to apply new diagnostic tools widely to strengthen helminthiases prevention and control in China.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors worldwide. Liver transplantation (LT) is known as a curative and therapeutic modality. However, the survival rates of recipients after LT are still not good enough because of tumor recurrence. To improve the survival rates of recipients after LT, identifying predictive factors for prognosis after LT and establishing a model assessing prognosis are very important to HCC patients. There has recently been a lot of clinical and basic research on recurrence and prognosis after LT. Progress has been made, especially in selection criteria for LT recipients and risk factors for predicting prognosis after LT. Hangzhou criteria, in line with China’s high current incidence rate of primary liver, are first proposed by Chinese scholars of LT, and are accepted world-wide, and make an important contribution to the development of LT.

Background The purpose of this study was to review the risks and benefits of concurrent chemoradiation therapy (CCRT) with esophageal self-expandable metal stents (SEMS) for the treatment of locally advanced esophageal cancer. Materials and Methods Between January 2014 and December 2016, the data from 46 locally advanced esophageal cancer patients who received CCRT at our institution were retrospectively reviewed. Eight patients who received CCRT concomitant with SEMS placement (SEMS plus CCRT group) and thirty-eight patients who received CCRT without SEMS placement (CCRT group) were identified. The risk of developing esophageal fistula and the overall survival of the two groups were analyzed. Results The rate of esophageal fistula formation during or after CCRT was 87.5% in the SEMS plus CCRT group and 2.6% in the CCRT group. The median doses of radiotherapy in the SEMS plus CCRT group and the CCRT group were 47.5 Gy and 50 Gy, respectively. SEMS combined with CCRT was associated with a greater risk of esophageal fistula formation than CCRT alone (hazard ratio [HR], 72.30; 95% confidence interval [CI], 8.62–606.12; p Conclusion CCRT concomitant with SEMS for locally advanced esophageal cancer results in earlier life-threatening morbidity and a higher mortality rate than treatment with CCRT alone. Further prospective and randomized studies are warranted to confirm these observations. Implications for Practice Patients treated with SEMS placement followed by CCRT had higher risk of esophageal fistula formation and inferior overall survival rate compared with patients treated with CCRT alone. SEMS placement should be performed cautiously in patients who are scheduled to receive CCRT with curative intent.

Background Extubation failure can lead to a longer intensive care unit (ICU) stay, higher mortality rate, and higher risk of requiring tracheostomy. Chest physiotherapy (CPT) can help patients in reducing the accumulation of airway secretion, preventing collapsed lung, improving lung compliance, and reducing comorbidities. Much research has investigated the correlation between CPT and respiratory system clearance. However, few studies have investigated the correlation between CPT and failed ventilator extubation. Therefore, this study aimed to investigate the use of CPT for reducing the rate of failed removal from mechanical ventilators. Methods This study was an intervention study with mechanical control. Subjects were divided into two groups. The control group, which received routine nursing chest care, was selected from a retrospective chart review. The intervention group was prospectively taken into the chest physiotherapy program. The chest physiotherapy treatment protocol consisted of inspiratory muscle training, manual hyperinflation, chest wall mobilization, secretion removal, cough function training, and early mobilization. Results A total of 439 subjects were enrolled in the intervention and control groups, with a mean age of 69 years. APACHE II score (P = .09) and GCS scores (P = .54) were similar between the two groups. Compared to the control group, patients in the intervention group had a significantly lower reintubation rate (8% vs 16%; P = .01). Conclusions The results indicate that intensive chest physiotherapy could decrease extubation failure in mechanically ventilated patients in the ICU. In addition, chest physiotherapy could also significantly improve the rapid shallow breathing index score.

Objective: To reveal the cutoff point and influencing factors in the dynamic change in phenotypic group in patients with stable angina pectoris (SAP) after Xinxuekang capsule treatment. Methods: Five hundred and seventy-six SAP patients were randomly assigned to receive Xinxuekang (XXK) capsules or Compound Danshen (CDS) tablets for 8 weeks. Global similarity degree analysis and nonlinear mixed effects modeling (NONMEM) were employed to reveal the cutoff points and influencing factors in dynamic changes in the SAP phenotypic group. The phenotypic group was defined as the six phenotypes in SAP, including angina, choking sensation in the chest, palpitations, dark purple lips, ecchymosis on the tongue, and fine-choppy pulse, which were quantitatively evaluated on Days 0, 14, 28, 42, and 56. Results: Variation in the six individual phenotypes and distribution of the SAP phenotypic profile were similar between the two experimental groups, but cutoff points for changes in the SAP phenotypic group were 7.28 and 10.73 weeks in XXK and CDS groups, respectively. Degree of severity of SAP as well as study site significantly affected the tendency for change in the SAP Xueyu Zheng in both XXK and CDS treatment groups. Different Chinese patent drugs affected the tendency for change in phenotypic group in patients with SAP. XXK was superior to CDS in controlling a clinical phenotypic group. Conclusion: Based on global similarity degree analysis and NONMEM, the cutoff point and influencing factors in phenomic variation of SAP may be determined, to improve the development and modification of treatment regimens.

The study was to establish a population pharmacokinetic (PPK) model of piperacillin (PIP) and tazobactam (TAZ) that explain pharmacokinetic variability and to propose optimized dosage regimens in patients with nosocomial infections. In total, 310 PIP and 280 TAZ concentration–time points were collected at steady state over multiple dosing intervals from 50 patients who received PIP/TAZ infused within 30 min or over 3 h. Drug analysis was performed by high-performance liquid chromatography (HPLC). Nonlinear mixed effects modeling was employed to develop PPK model and 1000 Monte Carlo simulation was used to predict the probability of target attainment (PTA) with a target time of non-protein-bound concentration above MIC > 50 % of the dosing interval. A model with one-compartment model had the best predictive performance for the PPK model. The population estimates of PIP were 13.8 L/h (31.1 %) for clearance (CL) and 21.7 L (38 %) for volume of distribution (V). The population estimates of TAZ were 9.3 L/h (29.1 %) for CL and 16 L (35.3 %) for V. Influence of creatinine clearance (CLcr) and body weight were identified as important covariates for PIP/TAZ CL and V, respectively. A 30-min infusion of 4 g every 6 h achieved robust (≥90 %) PTAs for MIC ≤ 16 mg/L. As an alternative mode of administration, a 3-h infusion of 4 g every 6 h achieved robust PTAs for Pseudomonas aeruginosa and Klebsiella pneumoniae. Prolonged infusions achieved better PTAs compared with shorter infusions at similar daily doses. This benefit was most pronounced for MICs between 16 and 40 mg/L.

Background The prognostic prediction of liver transplantation (LT) guides the donor organ allocation. However, there is currently no satisfactory model to predict the recipients’ outcome, especially for the patients with HBV cirrhosis-related hepatocellular carcinoma (HCC). The present study was to develop a quantitative assessment model for predicting the post-LT survival in HBV-related HCC patients. Methods Two hundred and thirty-eight LT recipients at the Liver Transplant Center, First Affiliated Hospital, Zhejiang University School of Medicine between 2008 and 2013 were included in this study. Their post-LT prognosis was recorded and multiple risk factors were analyzed using univariate and multivariate analyses in Cox regression. Results The score model was as follows: 0.114×(Child-Pugh score)-0.002×(positive HBV DNA detection time)+0.647x (number of tumor nodules)+0.055×(max diameter of tumor nodules)+0.231×lnAFP+0.437×(tumor differentiation grade). The receiver operating characteristic curve analysis showed that the area under the curve of the scoring model for predicting the post-LT survival was 0.887. The cut-off value was 1.27, which was associated with a sensitivity of 72.5% and a specificity of 90.7%, respectively. Conclusion The quantitative score model for predicting post-LT survival proved to be sensitive and specific.

This study aims to evaluate the adaptability and applicability of Guidelines for the Diagnosis and Treatment of Cancer in Traditional Chinese Medicine. The assessment methods included adaptability assessment and applicability assessment. The adaptability assessment was based on the questionnaire survey to evaluate the familiarity, utilization, quality, and clinical application of the Guidelines; applicability assessment was based on the prospective observation of 853 clinical cases to investigate the applicability and effect of the Guidelines, including effectiveness, economy and safety. Statistical analysis for basic description, construction of different comparison groups for cross or hierarchical statistical test, multi-factor analysis, and confounding factors were used in the study. Adaptability assessment results showed that 63.03% of TCM doctors considered guidelines as good or very good applicability and 4.24% of TCM doctors considered guidelines with very poor applicability in clinical practice. For the applicability evaluation, TCM doctors considered that the "overall efficacy and technology level", "satisfactory degree" and "adaptability in clinical practice" of the guideline were 85.46%, 80.43% and 69.40% respectively. The results showed that guideline was well known among TCM doctors, especially junior TCM doctors. Adaptability and applicability of Guidelines were totally good but the quality and adaptability of the intervention schemes were still week, so the quality of Guidelines should be improved by revision.

This study is to assess the Guidelines for Diagnosis and Treatment of Common Diseases of Otolaryngology in Traditional Chinese Medicine in clinical application and provide evidence for further guideline revision. The assessment was divided into applicability assessment and practicability assessment. The applicability assessment based on questionnaire survey and the traditional Chinese medicine (TCM) practitioners were asked to independently fill the Questionnaire for Applicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The practicability assessment was based on prospective case investigation and analysis method and the TCM practitioners-in-charge filled the Case Investigation Questionnaire for Practicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The data were analyzed in descriptive statistics. 151 questionnaires were investigated for applicability assessment and 1 016 patients were included for practicability assessment. The results showed that 88.74% of them were familiar with the guidelines and 45.70% used them. The guidelines quality and related items were similar in applicability assessment and practicability assessment, and scored highly as more than 85.00% except the "recuperating and prevention". The results suggested that the quality of Guidelines for Diagnosis and Treatment of Common Diseases of Otolaryngology in Traditional Chinese Medicine was high and could better guide the clinical practice. The "recuperating and prevention" part should be improved and the evidence data should be included in future guideline revision, so that the clinical utilization rate could be increased.

To evaluate the clinical applicability and application of Guidelines for Diagnosis and Treatment of Common Diseases of Gynecology in Traditional Chinese Medicine, 11 diseases from Guidelines for Diagnosis and Treatment of Common Diseases of Gynecology in Traditional Chinese Medicine were evaluated by methods of questionnaire and prospective case study at 16 construction units for traditional Chinese medicine standards research and extension. Results showed that 361 clinical doctors accepted the applicability survey of guidelines, and 87.26% of them were more familiar to the guideline and 25.21% of them used the guideline. In syndrome differentiation and treatment related contents, rationality of prescription medication and syndrome classification was higher, accounted for 91.69% and 86.98% respectively, but the rationality of recuperation prevention was lower, accounted for 44.6%. 75.62% clinical doctors believed that the Guidelines for Diagnosis and Treatment of Common Diseases of Gynecology in Traditional Chinese Medicine was applicable. The application of the guidelines is evaluated by prospective observation of 2 935 cases. The higher compliance between the guideline and clinical practice was present in TCM (traditional Chinese medicine) disease diagnosis and WM (western medicine) disease diagnosis, accounted for 98.30% and 94.11% respectively. The lower compliance was present in recuperation prevention, accounted for 59.39%. The safety and economy of the guideline was higher, accounting for 95.64%, 94.75%, respectively. The comprehensive evaluation results showed that the rate of the overall treatment effect with technical level, satisfaction degree or applicability in clinical practice which were 7-9 points is 77.38%, 74.00%, 76.90% respectively. This guideline has a high clinical compliance and can be used as a standard for common diseases of gynecology, but there are also some conditions with poor applicability, which does not conform to the actual situation, and needs to be further revised.

To assess the quality and application effect of Guidelines for Diagnosis and Treatment of Common Diseases of Dermatology in Traditional Chinese Medicine(Guidelines) through the applicability and applicability evaluation respectively. The questionnaire survey was adopted to evaluate the applicability of the Guidelines, including the utilization, quality, and clinical application conditions. The results showed that the familiarity rate and utilization rate of the Guidelines were 85.37%, 48.78%, respectively. The data showed that the familiarity and the utilization rates were different in the working staff with different professional titles. The evaluation level was the lowest given by the staff with junior professional title (70.97%, 29.03%) in comparison. The assessment showed the overall quality of the Guideline was good and slightly low level for the rationality scores of the other therapeutic methods as well as for the recuperation and prevention (80.49%, 85.37%), which was in line with the clinical compliance of the Guideline. The perspective observation of clinical cases was used for the applicability evaluation, including clinical compliance of the Guideline, effect evaluation, and comprehensive assessment, et al. The results showed that the safety score was the highest, followed by the economic issue and efficacy.

Gastric cancer is the second leading cause of cancer mortality in the world. HER family tyrosine kinases play a critical role in the development of gastric cancer. The HER family of receptor tyrosine kinases includes EGF receptor (EGFR), HER2, HER3, and HER4. Targeted drugs antineoplastic therapies such as EGFR tyrosine kinase inhibitors have application with confrontation of gastric cancer. However, less attention has been paid to the oncogenic functions of HER3 essepecially in the gastric cancer due to its lack of intrinsic kinase activity. Recent work, however, has placed the role of HER3 in gastric cancer in the spotlight as a key signaling hub in several contexts. First, HER3 overexpression may be associated with poor prognosis and unfavorable survival mediated by PI3K/AKT signaling pathway. Second, a large amount of direct evidence has emerged the benefit of anti-HER3 agents in combination with EGFR tyrosine kinase inhibitors as well as anti-HER2 agents in gastric cancer. Furthermore, we can further elucidate the relationship between HER3 and MET inhibitors in gastric cancer that the development of resistance to MET inhibitors may result from the overexpression of HER3. This review focuses on the current achievements of the relationship between HER3 and gastric cancer in vivo and in vitro, the development of HER3 molecule-targeted therapy, additionally, the challenge which we will meet in the future.

Background Kashi Prefecture of Xinjiang is one of the most seriously affected areas with anthroponotic visceral leishmaniasis in China. A better understanding of space distribution features in this area was needed to guide strategies to eliminate visceral leishmaniasis from highly endemic areas. We performed a spatial analysis using the data collected in Bosh Klum Township in Xinjiang China. Methods Based on the report of endemic diseases between 1990 and 2005, three villages with a high number of visceral leishmaniasis cases in Bosh Klum Township were selected. We conducted a household survey to collect the baseline data of kala-azar patients using standard case definitions. The geographical information was recorded with GIS equipment. A binomial distribution fitting test, runs test, and Scan statistical analysis were used to assess the space distribution of the study area. Results The result of the binomial distribution fitting test showed that the distribution of visceral leishmaniasis cases in local families was inconsistent (χ2 = 53.23, P

To observe the effectiveness and safety of external applying Compound Tripterygium wilfordii Hook F. (TwHF) in relieving joint pain in rheumatoid arthritis (RA) patients.In this double-blinded, randomized multicenter trial, a total of 174 moderately active RA patients were enrolled and randomly assigned to the treatment group (treated with Compound TwHF, 87 cases) and the placebo control group (87 cases). Compound TwHF or placebo was externally applied in painful joints, 20 g each time, once per day for 8 weeks. Self-reported joint pain relief was taken as a primary effective indicator. Visual analogue scale for pain (VAS), disease activity score of 28 joints (DAS28), VAS for general health (GH) were evaluated before treatment, at week 4 and after treatment. Erythrocyte sedimentation rate (ESR) and hypersensitive C reactive protein (hs-CRP) were tested before and after treatment. Menstrual changes in females were observed during treatment. Skin irritation occurred during the recording process was assessed using skin irritation strength. Intention to treat (ITT) was statistically analyzed.The joint pain relief rate in the treatment group was 90.8% (79/87 cases), higher than that in the placebo control group (69.0%, 60/87 cases; P = 0.001). VAS pain score, DAS28, VAS for GH score were significantly improved in the two groups at week 4 of treatment and after treatment, as compared with before treatment (P0.01). ESR and hs-CRP levels significantly decreased in the treatment group after treatment (P0.05, P0.01). No difference was found in post-treatment VAS pain score, DAS28, VAS for GH score, ESR, or hs-CRP between the two groups (P0.05). Eight adverse events occurred in the treatment group (5 skin allergy, 1 intolerance of medical odor, and 2 mild liver injury), while 3 adverse events occurred in the placebo control group (2 skin allergy, 1 mild liver injury). There was no statistical difference in adverse event between the two groups (P0.05). No menstrual change occurred in the treatment group.External applying Compound TwHF was an effective and safe way to relieve-joint pain of RA patients, which could be taken as an adjuvant therapy.

To understand the ability of worm detection of staff of centers for disease control and prevention (CDC) in China, so as to promote the ability construction.In each province, four competitors were selected from the institutions of parasitic diseases control to attend the National Technique Competition for Parasitic Disease Diagnosis and the results of competition were collected and analyzed.The average scores of microscopic identification and slide preparation of all the 124 competitors were 27.3 and 7.6 respectively and the scores were increased significantly (t = 3.169, 5.009, both P0.05) compared to those in 2012. The average detection rate of helminthes was 62.7%, and it was increased significantly (χ2 = 28.630, P0.05) compared to that in 2012. The scores of competitors of different genders, ages, and profession titles were significantly different (t = 1.400, 2.080, F = 2.366-3.864, all P0.05). The scores of competitors of provinces with the control task of parasites were higher than those without any control task (t = 6.650, 4.630, both P0.01).The competition has enhanced the ability of staff of CDCs, especially for the young staff. However, the ability of detection for soil transmitted helminth eggs should be intensified. Monitoring sites should be established in low endemic areas of parasites and provinces without the prevention and control task and the training for the professional staff should be strengthened.

Background To examine the effects of norcantharidin (NCTD) on development of human myeloid dendritic cells (DCs) in vitro and in skin allograft transplantation in vivo. Methods Human CD14(+) monocytes were isolated and triggered differentiation and maturation toward myeloid DCs with and without NCTD. The cell morphology, viability, cell death, expression of surface markers and co-stimulatory molecules, allostimulatory activity, and cytokine production were examined for characterization of DCs. The rejection of mice skin allograft model was used to translate the in vitro effect of cantharidin (CTD) and NCTD on DCs. Results DCs developed in the presence of NCTD showed decreased viability, cell death with necrosis, and lower expression of CD1a and CD83. DCs triggered in the presence of NCTD possessed a greater allostimulatory activity in naive CD4(+)CD45RA(+) T cells. NCTD modulated DCs through calcineurin phosphatase but not through mammalian target of rapamycin or downstream molecule p70S6 kinase. In vivo, NCTD caused accumulation and co-localization of antigen-presenting cells and regulatory T cells in the interfollicular area of the recipients' spleens. CTD and NCTD prolonged skin allograft survival along with less severe histopathological inflammatory reactions. CTD, but not NCTD, treatment caused elevation of serum alanine aminotransferase and evident mortality of the recipients. Conclusion NCTD modulated the differentiation and maturation of human myeloid DCs and caused deviation of standard DC differentiation toward a tolerogenic phenotype through calcineurin phosphatase inhibition. In vivo, both drugs effectively prolonged skin allograft survival. NCTD was less toxic than CTD, and thus, has potential for development as an immunosuppressant for transplant rejection.

Background/purpose Early physical training is necessary for severely deconditioned patients undergoing prolonged mechanical ventilation (PMV), because survivors often experience prolonged recovery. Long-term outcomes after physical training have not been measured; therefore, we investigated outcome during a 1-year period after physical training for the PMV patients. Methods We conducted a prospective randomized control trial in a respiratory care center. Thirty-four patients were randomly assigned to the rehabilitation group (n = 18) and the control group (n = 16). The rehabilitation group participated in supervised physical therapy training for 6 weeks, and continued in an unsupervised maintenance program for 6 more weeks. The functional independence measurement (FIM) was used to assess functional status. Survival status during the year after enrollment, the number of survivors discharged, and the number free from ventilator support were collected. These outcome parameters were assessed at entry, immediately after the 6 weeks physical therapy training period, after 6 weeks unsupervised maintenance exercise program, and 6 months and 12 months after study entry. Results The scores of total FIM, motor domain, cognitive domain, and some sub-items, except for the walking/wheelchair sub-item, increased significantly in the rehabilitation group at 6 months postenrollment, but remained unchanged for the control group. The eating, comprehension, expression, and social interaction subscales reached the 7-point complete independence level at 6 months in the rehabilitation group, but not in the control group. The 1-year survival rate for the rehabilitation group was 70%, which was significantly higher than that for the control group (25%), although the proportion of patients discharged and who were ventilator-free in the rehabilitation and control groups did not differ significantly. Conclusion Six weeks physical therapy training plus 6 weeks unsupervised maintenance exercise enhanced functional levels and increased survival for the PMV patients compared with those with no such intervention. Early physical therapy interventions are needed for the PMV patients in respiratory care centers. [J Formos Med Assoc 2011; 110(X):XX–XX]

Background Schistosoma japonicum causes an infection involving humans, livestock, and snails and is a significant cause of morbidity in China. Methods We evaluated a comprehensive control strategy in two intervention villages and two control villages along Poyang Lake in the southeastern province of Jiangxi, where annual synchronous chemotherapy is routinely used. New interventions, implemented from 2005 through 2007, included removing cattle from snail-infested grasslands, providing farmers with mechanized farm equipment, improving sanitation by supplying tap water and building lavatories and latrines, providing boats with fecal-matter containers, and implementing an intensive health-education program. During the intervention period, we observed changes in S. japonicum infection in humans, measured the rate of infection in snails, and tested the infectivity of lake water in mice. Results After three transmission seasons, the rate of infection in humans decreased to less than 1.0% in the intervention villages, from 11.3% to 0.7% in one village and from 4.0% to 0.9% in the other (P

Although the number of human infections decreased, human prevalence increased from 4.9% in 1995 to 5.1% in 2004., Results from the third nationwide cluster sampling survey on the epidemiology of schistosomiasis in the People’s Republic of China, conducted by the Ministry of Health in 2004, are presented. A stratified cluster random sampling technique was used, and 239 villages were selected in 7 provinces where Schistosoma japonicum remains endemic. A total of 250,987 residents 6–65 years of age were included in the survey. Estimated prevalence rates in the provinces of Hunan, Hubei, Jiangxi, Anhui, Yunnan, Sichuan, and Jiangsu were 4.2%, 3.8%, 3.1%, 2.2%, 1.7%, 0.9%, and 0.3%, respectively. The highest prevalence rates were in the lake and marshland region (3.8%) and the lowest rates were in the plain region with waterway networks (0.06%). Extrapolation to all residents in schistosome-endemic areas indicated 726,112 infections. This indicates a reduction of 16.1% compared with a nationwide survey conducted in 1995. However, human infection rates increased by 3.9% in settings where transmission is ongoing.
