Objectives: This study evaluated the impact of self-management interventions based on the COM-B model on peri-implant conditions in older adults with periodontitis. Materials and methods: The patients were randomly divided into two groups: Group 1 (control group) received only an oral health education (OHE) pamphlet. Group 2 (test group) performed a self-management intervention based on the COM-B model. Each patient was examined for the most inflammatory implant. The measurement parameters included self-efficacy, self-management ability, and clinical indicators such as probing depth (PD), bleeding on probing (BOP), modified gingival index (mGI), modified plaque index (mPI), and peri-implant mucositis severity score (PMSS). The data was collected at baseline, 4, 8, and 12 weeks. Results: 42 patients underwent testing for 3 months. After 12 weeks, the improvement of self-efficacy, self-management ability, and the reduction of BOP, mPI, and PMSS in the test group was significantly higher than in the control group. Conclusion: The study suggests that self-management interventions based on the COM-B model can enhance the self-management ability of older adults with periodontitis and reduce peri-implant inflammation. This method is more effective than distributing OHE pamphlets. Trial registration: The randomized controlled clinical trial was registered on Chinese Clinical Trial Registry (No. ChiCTR2400082660, Date: 03/04/2024). [ABSTRACT FROM AUTHOR]

This study investigated the mediating role of perceived stress in long-term development of posttraumatic stress symptoms (PTSS) and emotional distress among local government officials over seven years after the Wenchuan earthquake in China. Moreover, how dysfunctional coping would impact the relationship between perceived stress and PTSS or emotional distress was examined. Data were collected one year (T1) and seven years (T2) after the earthquake. Trauma experience, PTSS, and emotional distress were measured at one year. PTSS and emotional distress were re-assessed at seven years together with perceived stress and dysfunctional coping (i.e., behavioral disengagement, denial, self-distraction, self-blame, substance use, and venting). Mediation analyses were conducted to examine the mediating role of perceived stress. Moderated mediation analyses were performed to test the moderation effect of dysfunctional coping. Perceived stress fully mediated the association of T1 emotional distress with its' T2 scores (indirect effect: B = 0.10, SE = 0.04, β = 0.11, 95% CI [0.02, 0.18]), while did not mediate the association of T1 PTSS with T2 PTSS (indirect effect: B = 0.04, SE = 0.03, β = 0.04, 95% CI [−0.02, 0.10]). Compared to a low frequency use of dysfunctional coping strategies (ps = 0.148–0.326), the detrimental effects of perceived stress on PTSS and emotional distress were stronger at higher levels of dysfunctional coping strategies (ps < 0.001). This study highlights the importance of paying attention to the adverse impacts of perceived stress and dysfunctional coping on long-term mental health outcomes among local government officials after disasters.

Background Encouraging antitumor activity of nab-paclitaxel plus S-1 (AS) has been shown in several small-scale studies. This study compared the efficacy and safety of AS versus standard-of-care nab-paclitaxel plus gemcitabine (AG) as a first-line treatment for advanced pancreatic cancer (PC). Methods In this multicenter, randomized, phase II trial, eligible patients with unresectable, locally advanced, or metastatic PC were recruited and randomly assigned (1:1) to receive AS (nab-paclitaxel 125 mg/m2 on days 1 and 8; S-1 twice daily on days 1 through 14) or AG (nab-paclitaxel 125 mg/m2 on days 1 and 8; gemcitabine 1000 mg/m2 on days 1 and 8) for 6 cycles. The primary endpoint was progression-free survival (PFS). Results Between July 16, 2019, and September 9, 2022, 62 patients (AS, n  = 32; AG, n  = 30) were treated and evaluated. With a median follow-up of 8.36 months at preplanned interim analysis (data cutoff, March 24, 2023), the median PFS (8.48 vs 4.47 months; hazard ratio [HR], 0.402; P  = .002) and overall survival (OS; 13.73 vs 9.59 months; HR, 0.226; P  < .001) in the AS group were significantly longer compared to the AG group. More patients had objective response in the AS group than AG group (37.50% vs 6.67%; P  = .005). The most common grade 3-4 adverse events were neutropenia and leucopenia in both groups, and gamma glutamyl transferase increase was observed only in the AG group. Conclusion The first-line AS regimen significantly extended both PFS and OS of Chinese patients with advanced PC when compared with the AG regimen, with a comparable safety profile.

Death attitudes can have significant impacts on individuals' mental health. The present study used a person-centered approach to identify 588 Chinese college students' profiles of death attitudes (i.e., fear of death, death avoidance, neutral acceptance, escape acceptance, and approach acceptance), as well as their associations with socio-demographic factors and mental health outcomes. Latent profile analysis identified five subgroups of students: healthy (28.8%), acceptant (11.7%), indifferent (43.5%), paradoxical (10.7%), and avoidant (5.3%). The healthy profile had the most favorable mental health outcomes, whereas the paradoxical profile had the least favorable mental health outcomes. Moreover, women and students from better-resourced universities were more likely to report adaptive patterns of death attitudes. Our findings demonstrated the advantages of using a person-centered approach to achieve a more nuanced understanding of Chinese college students' death attitudes in relation to their mental health. The findings can inform death-related education and mental health interventions for college students. [ABSTRACT FROM AUTHOR]

This study aimed to describe patient‐reported outcomes 2 years after burn injury and to comprehensively elucidate predictors that may influence these outcomes. This cross‐sectional, prospective study included 352 patients who were admitted to the Department of Burn Surgery at a tertiary teaching hospital between January 2017 and December 2020. We collected demographic and disease‐related data and instructed participants to complete the Readiness for Hospital Discharge Scale (RHDS) and the Burn Specific Health Scale‐Brief (BSHS‐B) questionnaire. The overall score of patient‐reported outcomes 2 years after burn injury was 126.55 ± 33.32 points, and the dimensions with the lowest scores were "hand function" (13.96 ± 5.75), "heat sensitivity" (14.84 ± 4.90), "treatment regimens" (13.41 ± 6.77) and "work" (11.30 ± 4.97). Multiple linear regression analysis revealed that less postburn pruritus, better readiness for hospital discharge, less total body surface area (TBSA), better social participation, white‐collar jobs, older age, better sleep quality and burns not caused by electricity were associated with better outcomes. Patients experienced poor patient‐reported outcomes 2 years after burn injury. Integrated rehabilitative care is necessary to address patients' unique needs and improve long‐term patient‐reported outcomes. [ABSTRACT FROM AUTHOR]

Introduction: Family‐focused practice has become an emerging paradigm in mental health services. However, little is known about family‐focused practice and associated factors in Chinese mental health workers. Aim: To examine family‐focused practice and associated factors in Chinese mental health workers. Method: A cross‐sectional survey was conducted in a convenience sample of mental health workers (n = 515) in Beijing, China. The Family‐Focused Mental Health Practice Questionnaire was used to measure family‐focused practice, as well as worker, workplace and client factors that might influence family‐focused practice. Multiple linear regression analysis was performed to investigate the factors associated with family‐focused practice. Results: On average, the participants exhibited a moderate level of engagement in family‐focused practice. The factors that most significantly influenced family‐focused practice in Chinese mental health workers were skill and knowledge, worker confidence and time and workload. Moreover, psychiatrists were found to engage more in family‐focused practice than psychiatric nurses, and community mental health workers were more active in family‐focused practice than hospital‐based ones. Discussion: This study provided important data concerning family‐focused practice and associated factors in Chinese mental health workers. Implications for Practice: The varying level of Chinese mental health workers to engage in family‐focused practice has advocacy, training, research and organizational implications for mental health services in China and elsewhere.

Objective: The muscle quality index (MQI) is a measurement of muscle quality that is directly related to overall health. There has been little study on the relationship between the muscle quality index and periodontitis in American people beyond 30 years. Therefore, this study aimed to explore the link between periodontitis and Muscle quality index (MQI) in older Americans. Methods: Three thousand two hundred fifty-eight individuals (aged 30 to 59) who participated in the National Health and Nutrition Examination Survey (NHANES) 2011–2014 were considered eligible for the cross-sectional investigation. A hand dynamometer was used to determine the handgrip strength (HGS). Dual-energy X-ray absorptiometry was employed to calculate ASM (DXA). MQIArm was calculated by dividing the dominant hand's HGS by the dominant arm's ASM (in kg/kg). MQIApp was calculated by dividing the dominant hand's HGS by the ASM (in kg/kg). MQItotal was calculated by dividing the sum of the dominant and non-dominant hands by the ASM (in kg/kg). To investigate the link between muscle quality index and periodontal disease, the weighted multivariable logistic regression models were used. Using generalized additive models, it was determined if a nonlinear connection existed. Then, we developed a two-piece linear regression model and calculated the inflection point using a recursive approach. A mediation study was performed to determine how much of the impact of MQItotal on periodontitis was mediated by potential variables. Results: Three thousand two hundred fifty-eight participants from the United States were enrolled. The OR (95% CI) for the relationship between MQItotal and periodontitis in the regression model with fully adjusted variables was 0.69 (0.53–0.91), for the connection between MQIArm and periodontitis was 0.90 (0.84–0.97), and for the association between MQIApp and periodontitis was 0.49 (0.30–0.80). MQItotal and periodontitis were shown to have a J-shaped relationship with a change point of 3.64. Before the change point, the OR (95% CI) was 0.69 (0.58, 0.82). In the analysis of drinking and married status, the interaction was statistically significant. Analysis of mediation showed that alcohol use was responsible for 0.4% (0.10 to 1.2) of the effect of MQItotal on periodontitis. Conclusion: In American adults aged over 30, the Muscle Quality Index (MQI) exhibited an independent negative correlation with moderate to severe periodontitis, demonstrating a J-shaped relationship. Furthermore, alcohol consumption may act as a mediator in the association between MQI and periodontitis. [ABSTRACT FROM AUTHOR]

Objective: To evaluate whether electroacupuncture (EA) would improve gastrointestinal function and clinical prognosis in patients with severe traumatic brain injury (TBI) complicocted by acute gastrointestinal injury (AGI). Methods: This multicenter, single-blind trial included patients with TBI and AGI admitted to 5 Chinese hospitals from September 2018 to December 2019. A total of 500 patients were randomized to the control or acupuncture groups using a random number table, 250 cases in each group. Patients in the control group received conventional treatment, including mannitol, nutritional support, epilepsy and infection prevention, and maintenance of water, electrolytes, and acid-base balance. While patients in the acupuncture group received EA intervention at bilateral Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Tianshu (ST 25), and Zhongwan (RN 12) acupoints in addition to the conventional treatment, 30 min per time, twice daily, for 7 d. The primary endpoint was 28-d mortality. The secondary endpoints were serum levels of D-lactic acid (D-lac), diamine oxidase (DAO), lipopolysaccharide (LPS), motilin (MTL) and gastrin (GAS), intra-abdominal pressure (IAP), bowel sounds, abdominal circumference, AGI grade, scores of gastrointestinal failure (GIF), Glasgow Coma Scale (GCS), Acute Physiology and Chronic Health Evaluation (APACHE II), Sequential Organ Failure Assessment (SOFA), and Multiple Organ Dysfunction Syndrome (MODS), mechanical ventilation time, intense care unit (ICU) stay, and the incidence of hospital-acquired pneumonia. Results: The 28-d mortality in the acupuncture group was lower than that in the control group (22.80% vs. 33.20%, P<0.05). Compared with the control group, the acupuncture group at 7 d showed lower GIF, APACHE II, SOFA, MODS scores, D-lac, DAO, LPS, IAP, and abdominal circumference and higher GCS score, MTL, GAS, and bowel sound frequency (all P<0.05). In addition, the above indices showed simillar changes at 7 d compared with days 1 and 3 (all P<0.05) in the EA group. Conclusion: Early EA can improve gastrointestinal function and clinical prognosis in patients with severe TBI complicated by AGI. (Registration No. ChiCTR2000032276) [ABSTRACT FROM AUTHOR]

Sarcopenic obesity is regarded as a risk factor for the progression and development of non-alcoholic fatty liver disease (NAFLD). Since male sex is a risk factor for NAFLD and skeletal muscle mass markedly varies between the sexes, we examined whether sex influences the association between appendicular skeletal muscle mass to visceral fat area ratio (SVR), that is, an index of skeletal muscle mass combined with abdominal obesity, and the histological severity of NAFLD. The SVR was measured by bioelectrical impedance in a cohort of 613 (M/F = 443/170) Chinese middle-aged individuals with biopsy-proven NAFLD. Multivariable logistic regression and subgroup analyses were used to test the association between SVR and the severity of NAFLD (i.e. non-alcoholic steatohepatitis (NASH) or NASH with the presence of any stage of liver fibrosis). NASH was identified by a NAFLD activity score ≥5, with a minimum score of 1 for each of its categories. The presence of fibrosis was classified as having a histological stage ≥1. The SVR was inversely associated with NASH in men (adjusted OR 0·62; 95 % CI 0·42, 0·92, P = 0·017 for NASH, adjusted OR 0·65; 95 % CI 0·43, 0·99, P = 0·043 for NASH with the presence of fibrosis), but not in women (1·47 (95 % CI 0·76, 2·83), P = 0·25 for NASH, and 1·45 (95 % CI 0·74, 2·83), P = 0·28 for NASH with the presence of fibrosis). There was a significant interaction for sex and SVR (Pinteraction = 0·017 for NASH and Pinteraction = 0·033 for NASH with the presence of fibrosis). Our findings show that lower skeletal muscle mass combined with abdominal obesity is strongly associated with the presence of NASH only in men. [ABSTRACT FROM AUTHOR]

Secreted protein, acidic and rich in cysteine (SPARC, also known as osteonectin), is a small molecule glycoprotein associated with cell secretions. The purpose of our research is to clarify the clinicopathological and prognostic significance of SPARC expression in breast cancer. In this study, we performed a meta-analysis and bioinformatics analysis using the PubMed, Web of Science, Wanfang Data, and CNKI databases. The meta-analysis showed that SPARC expression was elevated in breast cancer tissue, compared with normal tissue, while SPARC expression in tumor stromal cells was higher than that of tumor cells. The expression of SPARC was positively correlated with histological grade and TNM staging. The Kaplan-Meier plotter showed that low SPARC expression was negatively correlated with the overall, postprogression, and distant metastasis survival rates of patients. According to Oncomine database, SPARC expression was upregulated in breast cancer than normal tissues. In TCGA database, univariate analysis showed that lymph node metastasis, distant metastasis, and TNM staging were negatively correlated with patient prognosis in breast cancers. Cox multivariate analysis showed that age, lymph node metastasis, distant metastasis, and TNM staging were important factors affecting the survival time of breast cancer patients. SPARC expression can be employed as a good indicator of prognosis of breast cancer patients, which will provide new methods and ideas of preventive treatment. [ABSTRACT FROM AUTHOR]

Purpose: The objective of our study was to investigate the epidemiologic characteristics and prognostic factors in patients with pulmonary acinar cell carcinoma (PACC). Methods: PACC patients diagnosed between 1975 and 2016 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The trend in PACC incidence was assessed using joinpoint regression software. Overall survival (OS) and disease‐specific survival (DSS) were evaluated using the Kaplan–Meier method and log‐rank test. Univariate and multivariate Cox regression analysis was performed to identify the independent prognostic factors for OS and DSS. Nomograms to predict survival possibilities were constructed based on the identified independent prognostic factors. Results: A total of 2918 patients were identified with PACC. The mean age was 65.2 ± 8.95 years with a female to male of 1.6:1. The incidence of PACC steadily increased by an annual percentage change (APC) of 3.2% (95% CI 2.1–4.4, p < 0.05). Multivariate Cox regression analysis revealed that age, gender, race, stage, grade, tumor size, number of positive lymph nodes, surgery, and chemotherapy were independent prognostic factors for survival. Nomograms specifically for PACC were constructed to predict 1‐ and 5‐year OS and DSS possibility, respectively. The concordance index (C‐index) and calibration plots showed the established nomograms had robust and accurate performance. Conclusion: PACC was rare but the incidence has been steadily increasing over the past four decades. Survival has improved in recent years. Surgery or chemotherapy could provide better OS and DSS. The established nomograms specifically for PACC were robust and accurate in predicting 1‐ and 5‐year OS and DSS. [ABSTRACT FROM AUTHOR]

Objective. Leucine-rich α2 glycoprotein 1 (LRG1) is a novel cytokine, which is believed to be involved in the inflammatory process of a series of diseases. However, the relationship between LRG1 and spinal cord injury (SCI) has not been reported. The purpose of our study is to determine the predictive value of LRG1 for the prognosis of pediatric SCI (PSCI). Methods. This study recruited 64 patients with confirmed PSCI and 40 healthy controls at Foshan Traditional Chinese Medicine Hospital from January 2016 to December 2020. The clinical information of all participants at the time of admission was recorded. Peripheral blood was collected, and commercial reagents were used to detect the level of serum LRG1. At the same time, the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) was used to assess the severity of PSCI. Results. All participants were divided into PSCI group (n = 64) and NC group (n = 40). There was no significant difference in clinical information (age, gender, heart rate, systolic blood pressure, diastolic blood pressure, sampling time from injury, white blood cells, and C-reactive protein) between the two groups (p > 0.05). According to the interquartile range of serum LRG1, we compared the motor and sensory scores of ISNCSCI and found that serum LRG1 levels were negatively correlated with the prognosis of PSCI patients (p < 0.001). The results of receiver operating curve (ROC) showed that the sensitivity, specificity, and AUC (Area Under the Curve) of serum LRG1 level in predicting the prognosis of PSCI were 68.4%, 69.1%, and 0.705, respectively. The cut-off value of serum LRG1 level predicting the prognosis of PSCI is 21.1 μg/ml. Conclusions. Serum LRG1 level is significantly increased in PSCI patients, and the elevated LRG1 level is negatively correlated with the prognosis of PSCI patients. Serum LRG1 may be a potentially useful biomarker for predicting PSCI. [ABSTRACT FROM AUTHOR]

Aim. The aim of this study was to explore whether letrozole and high-fat diets (HFD) can induce obese insulin-resistant polycystic ovary syndrome (PCOS) with intestinal flora dysbiosis in a rat model. We compared the changes in the intestinal flora of letrozole-induced rats fed with HFD or normal chow, to explore the effects of HFD and letrozole independently and synergistically on the intestinal flora. Methods. Five-week-old female Sprague Dawley (SD) rats were divided into four groups: control (C) group fed with regular diet; L1 group administered with letrozole and fed with regular diet; L2 group received letrozole and fed with HFD; and HFD group fed with HFD. At the end of the experiment, ovarian morphology, hormones, metabolism, oxidative stress, and inflammatory status of all rats were studied. 16S rDNA high-throughput sequencing was used to profile microbial communities, and various multivariate analysis approaches were used to quantitate microbial composition, abundance, and diversity. Results. Compared to the C group, the increased plasma fasting insulin and glucose, HOMA-IR, triglyceride, testosterone, and malondialdehyde were significantly higher in the L2 group, while high-density lipoprotein cholesterol was significantly lower in the L1 group and L2 group. The indices of Chao1 and the Abundance-based Coverage Estimator (ACE) (α-diversity) in the L2 and HFD groups were significantly lower than that in the C group. Bray–Curtis dissimilarity based principal coordinate analysis (PCoA) plots and analysis of similarities (ANOSIM) test showed obvious separations between the L2 group and C group, between the HFD group and C group, and between the L2 and HFD groups. At the phylum level, Firmicutes and ratio of Firmicutes and Bacteroidetes (F/B ratio) were increased in the L2 group; Bacteroidetes was decreased in the L2 and HFD groups. No significant differences in bacterial abundance between the C group and L1 group were observed at the phylum level. Based on linear discriminant analysis (LDA) effect size (LEfSe) analysis, the bacterial genera (the relative abundance > 0.1%, LDA > 3, p < 0.05) were selected as candidate bacterial signatures. They showed that the abundance of Vibrio was significantly increased in the L1 group; Bacteroides and Phascolarctobacterium were enriched in the HFD group, and Bacteroides, Phascolarctobacterium, Blautia, Parabacteroides, Akkermansia [Ruminococcus]_torques_group, and Anaerotruncus were enriched in the L2 group. Conclusion. The effect of letrozole on intestinal flora was not significant as HFD. HFD could destroy the balance of intestinal flora and aggravate the intestinal flora dysbiosis in PCOS. Letrozole-induced rats fed with HFD have many characteristics like human PCOS, including some metabolic disorders and intestinal flora dysbiosis. The dysbiosis was characterized by an increased Firmicutes/Bacteroidetes ratio, an expansion of Firmicutes, a contraction of Bacteroidetes, and the decreased microbial richness. Beta-diversity also showed significant differences in intestinal microflora, compared with control rats. [ABSTRACT FROM AUTHOR]

Objective. Cognitive impairment is considered to be an important complication of spinal cord injury (SCI), but its underlying mechanism remains unclear. The purpose of this study is to explore whether serum CCL21 can be used as a potential biomarker of cognitive impairment in SCI. Methods. In Neck-Shoulder and Lumbocrural Pain Hospital, Shandong First Medical University & Shandong Academy of Medical Sciences, hospitalized or treated acute SCI patients were included in the study as the SCI group (SCI). At the same time, a normal control group (NC) matching the age and sex of the SCI group was recruited in the outpatient clinic. Once the two groups were enrolled, their demographics and clinical characteristics were collected immediately. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum CCL21 levels within 24 hours of admission. Three months later, the Montreal Cognitive Assessment (MoCA) was used to test the cognitive function of the population. Results. A total of 84 SCI patients and 49 NC populations were eligible for inclusion in the study. There was no significant statistical difference in the demographics and clinical characteristics (age, gender, BMI, TG, LDL-C, FBG, SBP, and DBP) between the two groups (p > 0.05). Compared with the NC group, the SCI group had a higher serum CCL21 level (p < 0.001) and a lower MoCA score (p < 0.001). Serum CCL21 level in SCI was negatively correlated with MoCA score (p = 0.023). Multivariable analyses showed that serum CCL21 level is an independent prognostic factor of cognitive impairment in SCI. Conclusions. MoCA score has a linear relationship with serum CCL21 quartile, and SCI cognitive function has a negative correlation with serum CCL21. Serum CCL21 is an independent risk factor for cognitive impairment after SCI. [ABSTRACT FROM AUTHOR]

Objective. Interleukin-37 (IL-37) is a new cytokine that naturally inhibits inflammation. Inflammation plays an important role in acute spinal cord injury (SCI). The purpose of this study is to check whether serum IL-37 can be used as a clinical predictor of SCI. Methods. All subjects underwent venipuncture within 24 hours of enrollment to obtain peripheral blood and then centrifuged to obtain serum. The concentration of serum IL-37 was determined by enzyme-linked immunosorbent assay (ELISA). One month after the injury, the American Spinal Cord Injury Association (ASIA) impairment scale was used for neurological examination. Results. A total of 148 people were included in the study, including 52 normal controls (NC) and 96 patients with acute SCI within 24 hours of onset. The comparison of clinical baseline data (age, gender, BMI: body mass index, smoking, alcohol drinking, CHD: coronary heart disease, HBP: high blood pressure, and DM: diabetes mellitus) between the two groups was not statistically significant (p > 0.05). However, the serum IL-37 concentration of SCI patients was significantly higher than that of the NC group, and the difference was statistically significant (p < 0.001). And with the aggravation of SCI grade, the level of IL-37 increased significantly (p < 0.05). Pearson correlation analysis further showed that serum IL-37 concentration is negatively correlated with AISA motor score (r = − 0.327 , p < 0.05). Conclusion. The serum IL-37 concentration of SCI patients is significantly increased, and it is closely related to the recovery of motor function. We proved for the first time that serum IL-37 has prognostic value in patients with SCI. In addition, serum IL-37 may be used as a prognostic biomarker for SCI. [ABSTRACT FROM AUTHOR]

Background This study evaluated the role of two-dimensional speckle tracking echocardiography (2DSTE) for predicting left ventricular (LV) diastolic dysfunction in pacing-induced canine heart failure. Methods Pacing systems were implanted in 8 adult mongrel dogs, and continuous rapid right ventricular pacing (RVP, 240 beats/min) was maintained for 2 weeks. The obtained measurements from 2DSTE included global strain rate during early diastole (SRe) and during late diastole (SRa) in the longitudinal (L-SRe, L-SRa), circumferential (C-SRe, C-SRa), and radial directions (R-SRe, R-SRa). Changes in heart morphology were observed by light microscopy and transmission electron microscopy at 2 weeks. Results The onset of LV diastolic dysfunction with early systolic dysfunction occurred 3 days after RVP initiation. Most of the strain rate imaging indices were altered at 1 or 3 days after RVP onset and continued to worsen until heart failure developed. Light and transmission electron microscopy showed myocardial vacuolar degeneration and mitochondrial swelling in the left ventricular at 2 weeks after RVP onset. Pearson's correlation analysis revealed that parameters of conventional echocardiography and 2DSTE showed moderate correlation with LV pressure parameters, including [ABSTRACT FROM AUTHOR]

Objective: To assess the effectiveness of abdominal acupuncture at the endocrine and metabolic level in patients with obesity-type polycystic ovary syndrome (PCOS). Methods: Eighty-six women from the First Affiliated Hospital of Guangzhou Medical College with a diagnosis of PCOS (body-mass index [BMI] ≥25 kg/m2) were randomly assigned to receive 6 months of abdominal acupuncture (once a day) or oral metformin (250 mg three times daily in the first week, followed by 500 mg three times daily thereafter). BMI, waist-to-hip ratio (WHR), ovarian volume, menstrual frequency, homeostasis model assessment for insulin resistance (HOMA-IR), and Ferriman-Gallwey score were measured at the beginning of the study and after 6 months of treatment. Luteotrophic hormone (LH), testosterone, follicle-stimulating hormone (FSH), fasting blood glucose, 2-hour Postprandial blood glucose, fasting insulin, 2-hour postprandial blood insulin, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were also assessed. Results: According to the results at baseline and 6 months, BMI, WHR, Ferriman-Gallwey score, ovarian volume, luteotrophic hormone, ratio of luteotrophic hormone to follicle-stimulating hormone, testosterone, LDL-C, triglycerides, total cholesterol, fasting blood glucose, 2-hour postprandial blood glucose, fasting insulin, 2-hour postprandial blood insulin, and HOMA-IR were reduced significantly in the two groups ( p<0.05). Menstrual frequency and HDL-C ( p<0.05) increased significantly in both groups; follicle-stimulating hormone also increased in both groups, but the change was not significant ( p>0.05). The acupuncture group showed considerable advantages over the metformin group in terms of reduced BMI and WHR and increases in menstrual frequency ( p<0.05). Conclusion: Abdominal acupuncture and metformin improved the endocrine and metabolic function of patients with obesity-type PCOS. Abdominal acupuncture may be more effective in improving menstrual frequency, BMI, and WHR, with few adverse effects. [ABSTRACT FROM AUTHOR]

Abstract: Ethnopharmacological relevance: Caesalpinia sappan L. is distributed in Southeast Asia and also used as herbal medicine for the treatment of various diseases such as burning sensations, leprosy, dysentery, osteoarthritis and rheumatoid arthritis (RA). The overproduction of IL-6 plays an important role in the prognosis of RA, but the active compounds from the extracts of Caesalpinia sappan L. suppressing IL-6 production remain unknown. Aims of the study: Identifying the main active compounds of Caesalpinia sappan L. extracts inhibiting the IL-6 production in LPS-stimulated RAW 264.7 cells by partial least squares (PLS). Materials and methods: Sixty-four samples with different proportions of compounds were prepared from Caesalpinia sappan L. by supercritical CO2 fluid extraction (SCFE) and refluxing. Each of 64 samples was applied to RAW 264.7 cells with LPS to evaluate whether IL-6 production by LPS is affected by addition of each sample. The IL-6 production in medium was determined by ELISA and the inhibitory activity of each sample was analyzed. In addition, the fingerprints of these 64 samples were also established by ultra-performance liquid chromatography electrospray ionization tandem mass spectrometry (UPLC–MS). We used the PLS, a simplified method, to evaluate the results from IL-6 production and fingerprints. Results: Each of 64 samples markedly suppressed LPS-induced IL-6 production in RAW cells. The fingerprints by UPLC–MS clearly revealed variations among 64 samples produced in different extract conditions. The PLS analysis with IL-6 production and fingerprints by UPLC–MS suggested that the peaks 71, 93, 150, 157, 168 have more influence on the inhibitory activity of Caesalpinia sappan L. extracts. The peaks 71, 93, 150 are likely representing sappanone A, protosappanin E and neoprotosappanin, respectively. The peaks 157 and 168 are still at large. Conclusion: This is the first report that sappanone A, protosappanin E, neoprotosappanin and two unidentified compounds can be considered as possible active compounds that might inhibit IL-6 production. Further studies are needed to confirm the effectiveness of these five compounds on IL-6 production and possible mechanism. [Copyright &y& Elsevier]

Abstract: Ethnopharmacological relevance: Stage 3 is the key phase of chronic kidney disease. Traditional Chinese medicine (TCM) has been used for the treatment of chronic kidney disease. But a large sample trial is desirable. Materials and methods: A total of 578 Chinese patients with primary glomerulonephritis in CKD stage 3 were randomly assigned to three groups: patients received TCM (TCM group), benazepril (Ben group), TCM combined with benazepril (TCM+Ben group). Patients were followed up for 24 weeks. The primary endpoint was the time to the composite of 50% increased of serum creatinine, end stage renal disease or death. Results: eGFR in the TCM and the TCM+Ben group were improved (week 24 vs. baseline, P <0.05) while eGFR in the Ben group was decreased (week 24 vs. baseline, P >0.05). 24h urinary protein excretion (UP) and urinary albumin/creatinine (UAlb/Cr) were decreased in the TCM+Ben (week 24 vs. baseline, P <0.05) and the Ben group (week 24 vs. baseline, P >0.05). UP and UAlb/Cr were increased in the TCM group to week 12, then were stable (week 24 vs. baseline, P <0.05). The hemoglobin in the TCM group was also improved (week 24 vs. baseline, P <0.05). The accumulative survival rate in the TCM+Ben group was higher than that in the TCM group and the Ben group (P =0.044). Side effects in the TCM group were the lowest in these groups (P <0.05). The patients with dry cough in the TCM+Ben group and the Ben group were increased as compared with the TCM group (P <0.05). Hyperkalemia happened less frequently in the TCM group as compared with the other two groups (P =0.052). Conclusions: For the patients with CKD stage 3, TCM can improve eGFR and hemoglobin with lower side effects. Benazepril significantly decreased the proteinuria. Chinese medicine integrated with benazepril can ameliorate renal function and decrease proteinuria synergistically. [Copyright &y& Elsevier]
