Dialysis adequacy indexed by Kt/V in hemodialysis (HD) patients is recommended as a single-pool Kt/V of at least 1.2 per session thrice weekly. But many patients cannot achieve this adequacy target. Although dialysis time is the most important as a factor influencing Kt/V, it is difficult to prolong dialysis time in practice because of its economic impact and poor patient compliance. The aim of this study is to investigate the effect of increasing blood flow rate on dialysis adequacy in HD patients with low Kt/V. This study enrolled 36 HD patients with single-pool Kt/V <1.2 per session thrice weekly, which was measured in dialyzer blood flow rate of 230 mL/min. We increased 15% of blood flow rate in patients <65 kg of body weight and 20% in patients >65 kg. And then we compared Kt/V and urea reduction ratio (URR) between before and after increasing blood flow rate. The mean age was 48 ± 11 years (23–73 years), and the number of males was 25. Of the total patients, 24 patients had dry weight <65 kg. Mean dialysis duration was 52 ± 50 months (3–216 months). Mean Kt/V before increasing blood flow rate was 1.02 ± 0.09. It increased to 1.14 ± 0.12 after increasing blood flow rate (p < 0.001). Of the total 36 patients, 13 patients (36.1%) achieved adequacy target (Kt/V ≤ 1.2). Mean URR before increasing blood flow rate was 56.9 ± 4.0%. It also increased to 60.8 ± 4.1% (p < 0.001). Our data suggest that increasing blood flow rate by 15–20% of previous flow rate is effective in achieving dialysis adequacy in HD patients with low Kt/V. [ABSTRACT FROM AUTHOR]

Objective: To investigate the diagnosis, treatment and prognosis of ovarian yolk sac tumor (OYST). Methods: The clinicopathological data and follow-up data of 12 patients with OYST admitted to the Affiliated Hospital of Qingdao University from January 2013 to December 2020 were retrospectively analyzed, and the diagnosis, treatment and prognosis of OYST patients were summarized. Results: (1) The age of 12 patients with OYST ranged from 11 to 37 years, with a median age of 20 years. At the first visit, all 12 patients had pelvic masses. Reasons for seeing a doctor: 6 cases of abdominal distension and abdominal pain, 4 cases of mass in the lower abdomen, 1 case of vaginal bleeding, and 1 case of appendicitis. International Federation of Obstetrics and Gynecology (FIGO) 2014 staging: 4 cases in stage Ⅰa, 2 cases in stage Ⅰc, 1 case in stage Ⅱc, 4 cases in stage Ⅲc, and 1 case in stage Ⅳb. (2) All 12 patients were examined by color Doppler ultrasound before operation, among which 10 cases showed unilateral adnexal masses and 2 cases bilateral adnexal masses. The median maximum diameter of tumor was 16.5 cm (range: 6.0-28.0 cm). The preoperative levels of alpha fetoprotein (AFP) in 12 patients (all >1 210 μg/L) were significantly higher than normal (<25 μg/L). Among the 11 patients with cancer antigen 125 (CA 125 ) detection results, 9 patients showed elevated serum CA 125 levels. (3) Among the 12 patients, 8 young infertile patients who needed to preserve their reproductive function underwent appendectomy, 3 infertile patients underwent staged surgery for ovarian malignant germ cell tumor, and only one bilateral lesion and infertile patient underwent unsatisfactory staged surgery for ovarian malignant germ cell tumor. Of the 12 patients, 11 patients were given combined chemotherapy regimen of bleomycin, cisplatin, and etoposide (BEP) after operation. One patient without chemotherapy developed metastasis 3 months after operation, and was given BEP chemotherapy, and her condition was controlled. (4) The deadline for follow-up was December 31st, 2022, and the median follow-up time was 60 months (range: 25-115 months). All the 12 patients survived without tumor during the follow-up period, and the median disease-free survival time was 84.5 months (range: 25-115 months). Conclusions: OYST mostly occurs in children and young women. Color Doppler ultrasound examination and serum AFP and CA 125 detection have diagnostic value for OYST. Surgical treatment after diagnosis of OYST includes surgery to preserve reproductive function and timely and standardized chemotherapy after operation. The prognosis of patients is good regardless of stage.

Although many studies have already described the physiological effects of bee products, such as honey, propolis, pollen, and royal jelly, on livestock farming, the health benefits of the honeycomb are still not fully understood. The problem of drug residues and bacterial resistance caused by the abuse of antibiotics is becoming increasingly serious. For this reason, a safe, green substitute has to be sought. We conducted a comparative study of honeycomb extract (HE) and an antibiotic on growth performance, carcass traits, immunity, antioxidant function and intestinal microorganisms of yellow bantam broilers. A total of four hundred eighty 21-day-old female yellow bantam broilers were randomly divided into 5 groups of 6 replicates of 16 birds each. The 5 groups were as follows, with birds receiving a basal diet supplemented with 150 ppm (mg/kg) of chlortetracycline (CTE), a basal diet without HE (control group), and a basal diet with 0.1%, 0.15%, or 0.2% HE for 60 days. The results showed that HE addition significantly increased average daily feed intake (ADFI), average daily gain (ADG), decrease feed gain ratio (F/G) from 21 to 80 and 51 to 80 days of age compared to the control group, with all 3 HE addition groups having statistically identical values to the antibiotic group. HE implementation dramatically increased spleen index, serum immunoglobulin A (IgA), immunoglobulin M (IgM,), glutathione peroxide (GSH-Px), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and total cecum bacteria and Lactobacillus compared to the control group, numerically at the same level as, or even better than, the antibiotic group. HE and CTE both markly reduced serum malondialdehyde (MDA) concentration compared to the control group, with higher concentrations of HE reducing the effect more dramatically than antibiotics. Both HE and CTE significantly raised dressed yield compared to the control group. In summary, HE, as a potential antibiotic alternative, improved growth performance, carcass traits, immune function, serum antioxidant capacity and intestinal microorganisms in yellow bantam broilers. According to the cubic regression analyses, the recommended supplemental dose of HE was calculated to be 0.15 to 0.17% for female yellow bantam broilers between 21 and 80 d of age., (Copyright © 2022.

Objectives: To clarify the effect of initial periodontal therapy on the dynamic changes of oral (saliva, dorsal tongue and subgingival plaque) microbiota in periodontitis patients with or without type 2 diabetes mellitus (T2DM). Methods: A total of 14 patients with chronic periodontitis (CP group) and 14 CP patients with T2DM (CP-T2DM group) were included from Department of Periodontology, School and Hospital of Stomatology,Cheeloo College of Medicine, Shandong University. The microbial samples were collected from saliva, dorsal tongue and subgingival plaque of first molars at baseline, 1.5 and 3 months after initial periodontal therapy, and were detected by 16S rRNA (V3-V4 region) gene sequencing. The sequencing data were analyzed to obtain microbial distribution and community structure information. The same professional periodontist evaluated the periodontal status of patients according to periodontitis detection indices before and after initial periodontal therapy. Meanwhile, patients' blood samples were collected and related metabolic indices were evaluated. Results: After initial periodontal therapy, the glycosylated hemoglobin levels [(7.46±1.69)%] in CP-T2DM group were significantly improved than that at baseline [(7.65±1.34)%] ( t= 0.52, P =0.610). The probing depth of the sampling sites [CP group: (2.94±0.46) mm, CP-T2DM group: (2.95±0.35) mm] and bleeding index (CP group: 1.91±0.42, CP-T2DM group: 1.67±0.49) at 3 months after treatment were significantly decreased than the probing depth [CP group: (3.99±0.77) mm, CP-T2DM group: (3.80±0.76) mm] ( F= 25.61, P< 0.001; F= 17.63, P< 0.001) and bleeding index (CP group: 3.03±0.52, CP-T2DM group: 2.54±0.65) ( F= 28.43, P< 0.001; F= 20.21, P< 0.001) at baseline. The flora analysis showed that the α and β diversity indices of the same sites in the CP and CP-T2DM groups did not change significantly before and after the initial therapy, but the bacterial abundance at each site changed. There were commonalities and differences in the microbial composition of each site in the CP and CP-T2DM groups. Among them, the relative abundance of Proteobacteria in saliva and dorsal tongue samples of the two groups after treatment was basically consistent with the change trend in the subgingival plaque microbes. In the subgingival plaque of the CP group, the relative abundance of Proteobacteria showed a gradual increase with the prolongation of initial periodontal therapy; while in the CP-T2DM group, it showed a trend of first increase and then decrease. Syntrophy , Dethiosulfate, Methanobacteriaceae and TG5 in CP and CP-T2DM groups were all significantly dominant bacteria in subgingival plaque at baseline ( P< 0.05). Moreover, in the CP-T2DM group Spirochetes also showed a significant advantage. At 1.5 months after treatment, Rhizobacteria, Alcaligenes, Comamomons, Delftia, Blautella , etc. were dominant in subgingival plaque ( P< 0.05). Firmicutes , Clostridia/Clostridiales, Enterococci and Ruminococci showed significant differences at 3 months ( P< 0.05). Conclusions: Plaques in saliva and tongue dorsal could reflect the effects of initial periodontal therapy on the dynamic changes of microorganisms to a certain extent. CP and CP-T2DM patients had differences in microbial composition and responses to initial periodontal therapy.

We evaluated the combined effects of vacuumed hydrogen peroxide vapour (VHPV) and vacuum-sealed dry heat (vacuum heat, VH) to inactivate food-borne pathogens (Salmonella Typhimurium, Escherichia coli O157:H7 and Listeria monocytogenes) on alfalfa seeds. Alfalfa seeds inoculated with food-borne pathogens were sequentially treated initially with 1·0 ml of 0 or 30% VHPV for 1 min and later with dry heat (DH) or VH for 2 h, and the rate of seed germination was evaluated. The combination treatment decreased the populations of three food-borne pathogens below the limit of detection (1·0 log CFU per gram) on alfalfa seeds without decreasing germinability. The sequential treatment using VHPV and VH greatly reduced the total treatment time needed to inactivate pathogens on alfalfa seeds by more than 5 log CFU per gram. These results demonstrate that a combination of VHPV and VH has potentially employed as a new method for pasteurization of alfalfa seeds without affecting their germinability., (© 2022 The Society for Applied Microbiology.)

Background: To improve the safety and early detection of unexpected breast implant-related complications, the Korean Breast Implant Registry (K-BIR) was launched in 2020 in cooperation with the Korean Society of Plastic and Reconstructive Surgeons and the Korean Ministry of Food and Drug Safety, and a pilot study was conducted., Objective: This article provides an overview of our pilot study and experiences of the K-BIR., Methods: The dataset to be used in the pilot form of K-BIR was constructed by holding online surveys and meetings focusing on the global breast device registry's minimum dataset. A pilot study was implemented from April 1, 2020, to July 31, 2020, with six university teaching hospitals and four private clinics., Results: During the pilot study period, 325 patients, 451 procedures, and 366 implants were entered into the K-BIR. The most common procedure registered was augmentation mammaplasty (30%) for cosmetic indications, followed by direct-to-implant breast reconstruction (27%). Smooth silicone implant was the most common type (73%) of implant used. A feedback survey after the pilot study included questions about the registration rate compared with an actual procedure, entry time, reasons for difficulty in entry, and additional data needed., Conclusions: The continuous maintenance and development of K-BIR will require an effective dataset, a strengthened legal system for an opt-out registry and personal data protection, various incentives for increasing participation rates, and an electronic platform that patients, manufacturers, and clinicians can easily access. K-BIR has the potential to provide quality assurance and outcomes for research and post-market surveillance systems for breast implants as well as methods for enhancing patient safety., Competing Interests: Declaration of Competing Interest No author has any conflict of interest directly relevant to the content of this article., (Copyright © 2022 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Objective: The clinical characteristics of patients with primary central nervous system lymphoma-diffuse large B-cell lymphoma (PCNSL-DLBCL) and the effects of different treatment schemes on their survival and prognosis were analyzed retrospectively. Methods: A total of 49 patients with PCNSL-DLBCL who presented at the Tianjin Medical University General Hospital from July 2014 to December 2020 were included, and their clinical data were retrospectively analyzed. They were divided into four groups: the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group. The median overall survival (OS) and progression-free survival (PFS) were calculated, and the survival prognosis was compared by univariate and multivariate prognostic analysis. Results: The median OS time of the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group was 16.5 months, 4.5 months, 42 months, and not reached, respectively ( P <0.001) . The median PFS time of the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group was 7 months, 1.5 months, 20 months, and 5 months, respectively ( P =0.005) . Multivariate prognostic analysis showed that double expressor lymphoma, IESLG risk grade, and different treatment methods were the prognostic factors of PCNSL-DLBCL. Conclusion: The survival and prognosis of PCNSL-DLBCL are affected by different treatment schemes. The role of CD20 monoclonal antibody in the treatment of PCNSL-DLBCL is still controversial. The treatment scheme containing BTKi has great potential for PCNSL-DLBCL. RLZT scheme has a good prospect for elderly patients who cannot tolerate high-dose chemotherapy and radiotherapy.

Objective: To investigate the expression of SET-NUP214 fusion gene in hematological malignancies and to analyze its related clinical biological characteristics. Methods: The clinical data of 24 patients with SET-NUP214 fusion gene-positive hematological malignancies were retrospectively analyzed, and the Kaplan-Meier method was used for survival analysis. Results: Among the 24 patients with SET-NUP214 fusion gene, 15 cases of acute lymphoblastic leukemia (ALL) (13 cases of T-ALL and 2 cases of B-ALL) , 7 cases of acute myeloid leukemia (AML) , and 2 cases of T/myeloid mixed acute leukemia have been identified. The immunophenotype of 13 cases of T-ALL was mainly characterized by CD3(+)CD2(-), 73.3% of ALL was characterized by myeloid marker expression, and 85.7% of AML was characterized by CD7 expression. Complete remission (CR) was achieved in 22 patients (91.7%) after induction chemotherapy. All 24 patients received allogeneic hematopoietic stem cell transplantation (HSCT) . With a median follow-up of 24 months, the 3-year relapse free survival (RFS) of AML and ALL was 85.7% and 33.3%, respectively ( P =0.128) . Comparing 13 cases of SET-NUP214-positive and 62 cases of SET-NUP214-negative T-ALL, the CR rates of induction chemotherapy were 92.3% and 93.5% ( P =0.445) , and the 4-week CR rates of induction chemotherapy were 69.2% and 72.6%, respectively ( P =0.187) ; the differences were not statistically significant. After HSCT, the 3-year RFS of SET-NUP214(+)T-ALL and SET-NUP214(-)T-ALL was 38.5% and 66.4%, respectively ( P =0.028) , and the difference was statistically significant. Conclusion: The SET-NUP214 fusion gene is mainly detected in T cell-derived hematological malignancies, and the prognosis of SET-NUP214 positive T-ALL is relatively poor.

Objective: To evaluate the functional outcomes of repairing parietal and occipital defect after surgery for cancer by lower trapezius myocutaneous flap with latissimus dorsi. Methods: Retrospective analyses of eight patients were performed who underwent repairing parietal and occipital defects with dural exposure after surgeries for cancers from January 2015 to January 2020 in Tianjin Institute of Occupational Disease Control and Prevention (Tianjin Workers Hospital) and the Second Hospital of Tianjin Medical University, including 6 males and 2 females aged from 26 to 68 years old. The method for harvesting the lower trapezius myocutaneous flap was improved and thus the lower trapezius myocutaneous flaps with latissimus dorsi were used for repairing the parietal and occipital defects. The area of myocutaneous flap depended on the size of defect. Results: The defects were repaired with the flaps with areas ranging from 12 cm×8 cm to 17 cm×15 cm. Seven flaps survived after surgery and the wounds were healed. Blisters and bruise were observed at the distal end of one flap 2 days after operation, which were cured with dressing change for 10 days. All cases were followed-up for six months, with normal functions of the shoulder joints, aside from mild hypertrophic scar in donor site on the back. Conclusion: It is feasible to use the lower trapezius myocutaneous flap with latissimus dorsi to repair the parietal and occipital defect after surgery for cancer, and the clinical effect is satisfactory.

Recent studies have shown that chromium (Cr) could alleviate the negative effects of heat stress on livestock and poultry, but there is little information available to laying ducks. This study aimed to investigate the effects of dietary addition of chromium propionate on laying performance, egg quality, serum biochemical parameters and antioxidant status of laying ducks under hot (average 32 °C) and humid (average 75% relative humidity) summer conditions. A total of 900 66-week-old weight- and laying-matched Shanma laying ducks were randomly divided into five treatments, each with 6 replicates of 30 individually caged birds. The birds were fed either a basal diet or the basal diet supplemented with either 200, 400, 600, or 800 μg/kg Cr as chromium propionate. All laying ducks were given feed and water ad libitum for 5 weeks. The results showed that dietary supplementation with chromium propionate significantly increased the laying rate and yolk colour score (P < 0.05). Treatment with 400 μg/kg Cr as chromium propionate significantly decreased the feed/egg ratio by 5.4% (P < 0.05). Increased supplemental Cr from 0 to 800 μg/kg resulted in an increase in albumen height and the Haugh unit linearly (P < 0.05). Increased supplemental Cr decreased serum cortisol (P < 0.001, linear; P = 0.008, quadratic), heat shock protein-70 (P < 0.001, linear; P = 0.007, quadratic) and glucose (P = 0.007, linear), whereas it increased serum insulin (P = 0.011, Linear), total protein (P = 0.006, linear; P = 0.048, quadratic) and albumin (P = 0.035, linear; P = 0.088, quadratic). Dietary Cr levels increased the activities of superoxide dismutase and glutathione peroxidase, the total antioxidant capacity linearly and quadratically (P < 0.05). A linear and quadratic (P < 0.05) decrease of the malondialdehyde concentrations in response to dietary Cr level was observed. These results indicated that dietary supplementation of Cr as chromium propionate, particularly at 800 μg/kg could beneficially affect the laying rate, egg quality and antioxidant function, as well as modulate the blood biochemical parameters of laying ducks under heat stress conditions., (Copyright © 2020 The Authors.

Objective: To explore the application effect of sustainable skin-stretching device in scalp and soft tissue defect. Methods: From June 2017 to January 2020, 5 patients (3 males and 2 females, aged 31-57 (38.0±2.1) years) with large area of scalp and soft tissue defect and skull exposure were admitted to Department of Reparative and Reconstructive Surgery of the Second Hospital of Dalian Medical University. The wound area ranged from 16.0 cm×8.0 cm to 18.0 cm×12.0 cm. The sustainable skin-stretching device was installed after debridement operation for scalp wound. The wound was stretched from the 3rd day after installation of the device, at a basic speed of 1 mm/d and finished for 3 times on average. During stretching, close attention was paid to the changes in blood flow of the wound margin and the subjective feeling of the patients. When the result was negative in the squeezing and pinching test for wound margin after stretching, the further stretching was stopped, the final stretching state was maintained for 3 days, and the wounds were sutured directly. The wound healing during stretching of sustainable skin-stretching device and the occurrence of complications were observed. The rest wound areas after stretching for 5, 10, 15, and 20 days were measured. The wound healing and hair growth were observed during follow-up. Results: All the wounds of 5 patients was sutured directly after stretching for 19-23 d. There was no tension blister on the margin of wounds during stretching, and the margin of wounds healed well after being sutured without skin necrosis. After stretching treatment for 5-20 d, the wound areas were gradually decreased. During follow-up of 2-11 (4.5±1.5) months, the elasticity, color, feeling, and regenerated hair growth of the stretched scalp tissue were close to those of the surrounding normal skin tissue. The linear scar formed on the margin of wounds, but no scar formed on the wounds. Conclusions: The application of sustainable skin-stretching device can reduce the difficulty in repairing scalp and soft tissue defect, with the regenerated hair growing well after treatment, which is worthy of clinical promotion.

Objective: To evaluate the role of polysaccharide from Phellinus igniarius (PPI) in the improvement of oxidative stress, hepatic granuloma and hepatic fibrosis in Schistosoma japonicum-iniected in mice., Methods: The mouse model of schistosomiasis was established by S. japonicum cercariae infection via the abdomen. Balb/c mice were randomly assigned into 5 groups, including the healthy control group (Group A), infection control group (Group B), PPI treatment group (Group C), praziquantel treatment group (Group D) and PPI-praziquantel combination group (Group E), of 10 mice in each group. Each mouse in groups B, C, D and E was infected with (30 ± 2) S. japonicum cercariae. Then, mice in groups D and E were given praziquantel by gavage at a dose of 500 mg/kg for successive two days on day 42 post-infection, while mice in groups C and E were given PPI by gavage at a dose of 400 mg/kg for successive 30 days on day 42 post-infection. Histopathological changes of hepatic tissues were observed using hematoxylin-eosin (HE) staining, and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) were determined, while the activities of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), glutathione reductase (GSH-R) and glutathione (GSH) were detected in Mouse liver homogenates. The expression of transforming growth factor-beta (TGF-β) and alpha-smooth muscle actin (α-SMA) was quantified in hepatic tissues using immunohistochemistry, and the Nrf2 and Gsta4 gene expression was quantified using quantitative real-time PCR (qPCR) assay., Results: Untreated mice presented typical pathological changes of schistosomal hepatic disorders, while PPI treatment effectively alleviated hepatic egg granulomas and collagen deposition. S. japonicum infection resulted in aggravation of hepatic lipid peroxidation, induction of oxidative stress, elevated serum MDA level and a reduction in the activity of GSH and antioxidant enzymes activities in mice. As compared to infected but untreated mice, PPI treatment suppressed hepatic lipid peroxidation, increased the GSH activity and restored the activity of antioxidant enzymes. In addition, PPI treatment inhibited the TGF-β signaling pathway and up-regulated the Nrf2 and Gsta4 gene expression., Conclusions: PPI plays a critical role in the treatment of schistosomiasis-induced hepatic fibrosis. It may improve oxidative stress damages through up-regulating Nrf2 and Gsta4 gene expression, thereby suppressing the development of hepatic egg granulomas and hepatic fibrosis.

Objective: To investigate the correlation between serum bilirubin and cardiovascular autonomic neuropathy (CAN) in type 2 diabetes mellitus patients. Methods: A total of 369 patients with type 2 diabetes mellitus who were hospitalized at the Department of Endocrinology, Nanjing Jinling Hospital from April 2017 to October 2018 were enrolled, including 226 males and 143 females, with an average age of (54.6±12.1) years. According to cardiovascular reflex tests (CARTs), all the patients were divided into Non CAN group(149 patients without CAN) and CAN group (220 patients complicated with CAN). The difference of serum bilirubin levels between the two groups was compared. The differences of CARTs and the incidence of CAN were compared by tertiles of serum bilirubin levels. The binary logistic regression was used to analyze the risk factors for diabetic cardiovascular autonomic neuropathy. Results: The serum total bilirubin [(9.28±2.74) μmol/L vs (11.08±2.98) μmol/L, P< 0.001], direct bilirubin [(3.17±1.20) μmol/L vs (3.71±1.24) μmol/L, P< 0.001] and indirect bilirubin levels [(6.11±1.89) μmol/L vs (7.37±2.10) μmol/L, P< 0.001] in CAN group were significantly lower than that in Non CAN group. With the increase of serum bilirubin, the incidence of CAN decreased ( P< 0.01). Multivariate Logistic regression analysis showed that serum total bilirubin ( OR= 0.819, 95 %CI : 0.744-0.901, P< 0.001), direct bilirubin ( OR= 0.739, 95 %CI : 0.601-0.908, P= 0.004) and indirect bilirubin ( OR= 0.749, 95 %CI : 0.653-0.860, P< 0.001) were inversely correlated with the incidence of CAN. Conclusions: Within the physiological range, lower level of serum bilirubin is inversely correlated with the incidence of CAN. It is noteworthy to screen diabetic cardiovascular autonomic neuropathy in patients with type 2 diabetes mellitus who had a lower serum bilirubin level.

The shape of the earlobes has a variety of genetic significance. This study analyzed the frequencies of the earlobe shapes in the Korean population. Data were collected on randomly selected 500 males and 500 females in Daegu Metropolitan City, with all participant ages being in their twenties. Obtuse angled earlobes accounted for 41.2% of the earlobes observed, while acute angled earlobes prevalence was calculated at 38.8% and right angled earlobe was 20.0% of the total (sexes combined). In men, the acute angled earlobe was the most frequent type (43.0%), while the obtuse angled earlobe was the most frequent type in females (45.2%). These differences were statistically significant (p = 0.015). Overall, attached type earlobe (61.2%) was more frequent than free type earlobe. The attached type earlobe was more common in both sex groups (57.0% in male and 65.4% in female), and the proportion was significantly higher for females (p = 0.006). In conclusion, the findings in this study suggest that the attached earlobe type is the most common among Koreans, and the proportion of earlobe types among males and females is significantly different. Further studies are needed to understand the genetic background of earlobe types among Koreans., (Copyright © 2018 Elsevier GmbH. All rights reserved.)

Wu Jinshou()[(1785-1795)-(1844-1851)]once wanted to take the imperial examination, but in late Qing Dynasty, under the depressed situation of economics and politics, he was trapped in countryside as many lower intellectuals, and chose medicine as another way to earn a living. In fact, he was both a doctor and a literatus. He kept friends with scholars, such as Zhang Tingji, Yao Wentian, Lu Changchun, Wei Guangfu, and scholar-physicians like Chen XIshu, Lu zeng and also Xu Jin's family, famous doctors at that time. He changed status Flexibly. To some extent, he represented the basic appearance of the traditional Chinese practitioner. In Daoguang 11 years(1831), Wu Jinshou published Medincal Cases Records of Three physicians (《》), Yi Xiao Mi Chuan (《》), Wen Re Zhui Yan (《》). This naturally have business purpose and was market-oriented. He had influenced on the spread of Wuzhong(the name of Suzhou and its surrounding area in Ming and Qing Dynasty) medical books, and provided some topics to the study of the Wenbing academic history.

Intense pulsed light (IPL) is a broad spectrum incoherent light which is produced by high-output xenon lamp. Since the invention of the first-generation IPL in 1994, IPL technology has been developing rapidly and extensively utilized in multiple fields relevant to dermatology across the world. In 2004, the fourth-generation IPL system was introduced with the optimal pulse technology (OPT) and has soon been used for cosmetic purposes all over the world. In 2002, Dr. Toyos found that the meibomian gland dysfunction (MGD) and dye eye disease (DED)symptoms of the rosacea patients who received IPL treatment have been improving significantly, therefore he started to explore the application of IPL system to treatment of dry eye disease. Several recent clinical studies have demonstrated the therapeutic potential of IPL for improving the symptoms and signs of MGD and DED. However, the published data of IPL treatment for MGD and DED is limited, the mechanism of IPL treatment for MGD and DED remained unclear and more relevant researches needed to be done in the future. This article discusses the clinical application history and general mechanism of IPL, and introduces the treatment of IPL for MGD and DED. (Chin J Ophthalmol, 2018, 54: 140-143) .

Objective: Early and proper diagnosis of cancer is the most critical factor for the survival and treatment of veterinary cancer patients. In this study, we evaluated extracellular cyclic AMP-dependent protein kinase A (ECPKA) level in serum as a useful cancer biomarker in dogs., Methods: ECPKA levels were detected in sera from dogs with cancers (n = 48), benign tumours (n = 18), and non-tumour diseases (n = 102) as well as healthy control dogs (n = 54) utilizing enzyme-linked immunosorbent assay (ELISA)., Results: Sera from dogs bearing various types of cancer exhibited markedly increased levels of ECPKA by up to 7.1-, 8.8-, and 10.9-fold compared with those from dogs harbouring benign tumours, dogs with non-tumour diseases, and healthy control dogs, respectively (P < .0001). In addition, serum ECPKA level did not show statistically significant correlation with gender, breed, or age of dogs or their non-cancerous disease conditions., Conclusion: Our data strongly propose that detection of serum ECPKA level is a potential and specific diagnostic tool for cancer in dogs., (© 2017 John Wiley & Sons Ltd.)

Objective: To explore short-term effect of intense pulsed light (IPL) combined with meibomian gland expression in treating meibomian gland dysfunction (MGD). Methods: This study was a prospective, randomized, double-masked, controlled study. Forty-four MGD patients were enrolled in the study and received three consecutive IPL treatments with an interval of 4 weeks. One eye of each patient was randomly assigned as the study eye receiving the IPL therapy with an energy of 14-16 J/cm(2), and the fellow eye was as the control eye receiving a placebo therapy with 0 J/cm(2). Meibomian gland expression was immediately performed after the IPL treatment in both eyes. Efficacy was evaluated through assessment of the meibomian gland yielding secretion score (MGYSS) , SPEED questionnaire, tear film break-up time (TBUT), cornea fluorescein staining and infrared meibography. Safety was evaluated through best spectacle corrected visual acuity, intraocular pressure, slit lamp examination and fundus examination. These examinations were performed before and after each treatment. Results: Significant improvements were observed in the MGYSS and TBUT after IPL treatments ( P< 0.05). The improvements compared to the baseline of MGYSS at the upper eyelid in the treatment eyes were significantly higher than those in the control eyes after the first treatment ( Z= -2.036, P= 0.003). The improvements compared to baseline of MGYSS at the lower eyelid and the TBUT in the treatment eyes were significantly higher than those in the control eyes after the second treatment ( Z=- 2.999 and -2.036, respectively P= 0.007 and 0.042, respectively). SPEED and cornea fluorescein staining were decreased in both eyes after IPL treatments, but there was no statistical difference between the two eyes. No obvious complication was observed in the study. Conclusions: IPL treatment combined with meibomian gland expression is an efficient and safe therapy, and can increase meibomian gland yielding secretion, increase the TBUT, relieve the symptoms and repair the corneal epithelium defects for MGD eyes.

Two experiments were conducted to optimize the fermentation of cottonseed meal by Cellulosimicrobium funkei (C. funkei) for the ability of the bacteria to degrade aflatoxin B1 (AFB1) and then to evaluate the bacterial detoxification in ducklings. In experiment 1, the fermentation of cottonseed meal by C. funkei was improved by changing the inoculation amounts by 10% (108 cfu/mL), using a 1:0.5 material to water ratio at 35°C temperature for a 144 h reaction duration, which resulted in an 83.4% biodegradation of AFB1. In experiment 2, 112 one-day-old male Cherry Valley ducklings were randomly allocated to 4 experimental groups with 4 replicates of 7 birds each. For a period of 2 wk the controls received a base duckling diet (BD), a second group received a base diet contaminated with 10% AFB1 cottonseed meal (96.8 μg AFB1/kg), a third group was fed a base diet added with 5% unfermented and 5% fermented AFB1-contaminated cottonseed meal (57.0 μg AFB1/kg), and the fourth group was fed a base diet added with 10% AFB1-contaminated fermented cottonseed meal (16.0 μg AFB1/kg). The growth performance, relative organ weights, and serum biochemistry were analyzed. The results showed that the feed conversion ratio in the second group was lower than that of the controls at wk one and 2 (P < 0.05). Also, after 2 wk, group 2 ducklings had increased relative weights of the liver, kidneys, and spleen, increased activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), increased concentration of blood urea nitrogen (BUN) and creatinine (Crt), and decreased relative weight of Fabricius bursa (P < 0.05). In addition, the concentrations of total protein (TP) and albumin (ALB) in serum were also significantly higher at weeks one and 2 (P < 0.05). These alterations were attenuated or prevented when 5 or 10% fermented cottonseed meal substituted equal amounts of unfermented cottonseed meal in the diet. In conclusion, fermentation of AFB1-contaminated feed materials by C. funkei offers a new strategy to reduce the negative effects of aflatoxicosis in ducklings., (© 2016 Poultry Science Association Inc.)

The female healer is a special community in traditional Chinese medical professionals. Since the Song-Yuan Dynasties, although the literati class holding the social voices and the male healers acting as medical orthodoxy were always suspicious of the female healers' behaviors and their medical morality, and tarnished their images through all kinds of media. Meanwhile, the female healers were still badly needed on the account of recognition of distinction between sexes between both sexes due to the rising of neo-Confucianism. An excellent female healer could still earn wide respect from the society. Gu Dehua was a famous female healer from Wuzhong in the Qing Dynasty's Daoguang-Xianfeng period. By investigating Gu Delua's family conditions, deeds and works, and her career, the community of the female healers in the Ming-Qing Dynasties can be thus understood.

Background: Asthma in the elderly (aged ≥ 65 years old) is a significant concern with high morbidity, but the pathophysiology remains unclear particularly in late-onset asthma. Recent studies suggest staphylococcal enterotoxin IgE (SE-IgE) sensitization to be a risk factor for asthma in general populations; however, the associations have not been examined in late-onset elderly asthma., Objective: We aimed to examine the associations of SE-IgE sensitization with late-onset asthma in the elderly, using a database of elderly asthma cohort study., Methods: A total of 249 elderly patients with asthma and 98 controls were analysed. At baseline, patients were assessed for demographics, atopy, induced sputum profiles and comorbidities including chronic rhinosinusitis (CRS). Serum total IgE and SE-IgE levels were measured. Asthma severity was assessed on the basis of asthma outcomes during a 12-month follow-up period., Results: At baseline, serum SE-IgE concentrations were significantly higher in patients with asthma than in controls [median 0.16 (interquartile range 0.04-0.53) vs. 0.10 (0.01-0.19), P < 0.001]. Elderly asthma patients with high SE-IgE levels had specific characteristics of having more severe asthma, sputum eosinophilia and CRS, compared to those with lower SE-IgE levels. In multivariate logistic regression analyses, the associations between serum SE-IgE concentrations and severe asthma were significant, independently of covariables [SE-IgE-high (≥ 0.35 kU/L) vs. negative (< 0.10 kU/L) group: odds ratio 7.47, 95% confidence interval 1.86-30.03, P = 0.005]. Multiple correspondence analyses also showed that high serum SE-IgE level had close relationships with severe asthma, CRS and sputum eosinophilia together., Conclusions and Clinical Relevance: This is the first report on the significant associations of SE-IgE sensitization with late-onset asthma in the elderly, particularly severe eosinophilic asthma with CRS comorbidity. Our findings indicate a potential implication of SE in the high morbidity burden of elderly asthma and suggest clues to the pathogenesis of severe late-onset eosinophilic asthma in the elderly., (© 2015 John Wiley & Sons Ltd.)

Cough accompanying acute respiratory tract disorders is a self-limiting phenomenon, and it usually does not require sophisticated management. Chronic cough, in contrast, is a bothersome problem, considerably influencing the quality of life of affected individuals. Specialized cough clinics report that substantial proportion of their patients are middle aged-to-postmenopausal females who cough for years in response to otherwise non-tussigenic stimuli, without a clear underlying disease reason. A newly established entity - 'cough hypersensitivity syndrome' explains pathogenesis of this problem. However, the syndrome has not been generally accepted, and the guidelines regarding the diagnostic protocols and treatment are not yet available. The reason why females cough more than males do is unclear, but the analysis of literature and experience with the chronic cough patients allows selecting three main targets of hormonal background which can contribute to the enhanced coughing in females. They are as follows: increased activity of transient receptor potential (TRP) channels expressed on vagal C-fibers mediating cough, laryngeal hypersensitivity and laryngeal dysfunction with paradoxical vocal cord movement, and mast cells which are known to express receptors for female sexual hormones and are frequently found in the bronchoalveolar lavage in chronic cough patients. In this review we analyze the potential contribution of the factors above outlined to excessive cough in female subjects.

The proteolytic region of cytokeratin-19, referred to as CYFRA21-1, is a soluble molecule present in the serum and other body fluids, and is considered a tumor marker in several neoplastic diseases. To examine whether urinary or serum samples containing CYFRA21-1 can be used as biomarkers for bladder cancer, we conducted a comprehensive meta-analysis of 3 case-control studies. In all studies considered, patients with bladder cancer had a higher CYFRA21-1 level than healthy subjects. Subgroup analysis showed that patients with metastatic bladder cancer had a higher CYFRA21-1 level than those with locally invasive disease. However, no significant difference in CYFRA21-1 was observed between patients with stage I and stage II bladder cancer; there was also no difference in patients with stage II local bladder cancer and those with stage III local bladder cancer. Based on our results, CYFRA21-1 level may be a diagnostic biomarker for diagnosing bladder cancer as well as a possible biomarker for differentiation between local and metastatic bladder cancer. However, it cannot be used as a urinary or serum biomarker for differentiating histological stages of local bladder cancer for histological grades I-III.

Google Trends (GT) is a Web-based surveillance tool used to explore the searching trends of specific queries on Google. Recent studies have suggested the utility of GT in predicting outbreaks of influenza and other diseases. However, this utility has not been thoroughly evaluated for allergic diseases. Therefore, we investigated the utility of GT for predicting the epidemiology of allergic rhinitis. In the USA, GT for allergic rhinitis showed repetitive seasonality that peaked in late April and early May and then rapidly decreased, and a second small peak occurred in September. These trends are highly correlated with the searching trends for other queries such as 'pollen count', antihistamines such as loratadine and cetirizine (all r > 0.88 and all P < 0.001), and even the total pollen count collected from 21 pollen counters across the USA (r = 0.928, P < 0.001). Google Trends for allergic rhinitis was similar to the monthly changes in rhinitis symptoms according to the US National Health and Nutrition Examination Survey III, sales for Claritin(®) and all over-the-counter antihistamines, and the number of monthly page views of 'claritin.com'. In conclusion, GT closely reflects the real-world epidemiology of allergic rhinitis in the USA and could potentially be used as a monitoring tool for allergic rhinitis., (© 2014 John Wiley & Sons A/S.

Aims: This study evaluated the combined effects of ozone and heat treatment to inactivate Escherichia coli O157:H7 and Salmonella Typhimurium in three types of apple juice of different soluble solids content., Methods and Results: Three types of apple juice (18, 36, 72 °Brix) inoculated with pathogens were subjected to ozone (3·0 l min(-1) flow rate and 2·0-3·0 g m(-3) concentration) and heat treatment (25, 45, 50 and 55°C) simultaneously for 20, 40 and 60 s. Initial populations of pathogens in inoculated apple juice were approximately 10(5)-10(6) CFU ml(-1). Heat treatment alone (25, 45, 50 and 55°C) for 1 min reduced populations of E. coli O157:H7 by 0 to 4·75 log CFU ml(-1) in three types of apple juice. The combination of ozone and heat treatment for 1 min at 25 and 45°C reduced E. coli O157:H7 by 0·93-3·87 log CFU ml(-1) and below the detection limit (>1 log CFU ml(-1)) at 50 and 55°C. A similar tendency was observed for S. Typhimurium. In several instances, results showed a synergistic effect of ozone and heat treatment. Colour values were not changed during ozone and heat treatment., Conclusion: These results show that the combination of ozone and heat treatment can be used as a potential inactivation intervention for E. coli O157:H7 and S. Typhimurium in apple juice., Significance and Impact of the Study: The combination of ozone treatment and mild heat can be used as an alternative intervention for pasteurization of varying soluble solids content apple juice in food industries., (© 2014 The Society for Applied Microbiology.)
