ObjectiveTo investigate the effects of lipopolysaccharide ( LPS ) on cell apoptosis,proliferation, and insulin secretion in a β-cell line, NIT-1. MethodsNIT-1 cells were stimulated with 1 μg/ml LPS for 0-120 h. Cell apoptosis was evaluated by Hochest33342 staining and Annexin V/PI flow cytometry. Cell proliferation was evaluated by CCK-8 and BrdU assay. Intracellular insulin content, basal insulin secretion, and glucose-stimulated insulin secretion(GSIS) were detected by RIA. The IRS-2 tyrosine phosphorylation was determined by Western blot. ResultsCell apoptosis was not significantly changed by treatment with LPS for 120 h. Cell proliferation was stimulated by LPS before 48 h, and inhibited after 96 h. Intracellular insulin content or GSIS was not altered, but basal insulin secretion was decreased significantly by LPS after 48 h ( all P＜0.01 ). LPS decreased the tyrosine phosphorylation level of IRS-2 ( 0. 45 ± 0. 08 vs 0. 22 ± 0. 06, P ＜ 0. 05 ) and stimulated IκBα phosphorylation. Pretreatment with a specific IκBα phosphorylation inhibitor, Bay1 1-7082 for 1 h, remarkably blunted the LPS-induced phosphorylation of IκBα and cell proliferation( both P＜0.01 ). ConclusionsLow-dosages of LPS regulate proliferation and basal insulin secretion of NIT-1 β-cells, in which activation of NF-κB and inhibition of IRS2 tyrosine-phosphorylation may be involved.

Objective To investigate the effects of Shanzha Xiaozhi capsule on body weight, metabolic index, percentage and distribution of body fat in obese patients with dampness-heat constitution. Methods A total of 60 obesity patients with dampness-heat constitution were enrolled in this study and randomly categorized into the control group ( n=30) and treatment group (n=30). Control group was given the diet and exercise regime, and treatment group was given Shanzha Xiaozhi capsule based on the same diet and exercise regime for 12 weeks. Scores of dampness-heat, body weight, waist circumference, hip circumference, blood pressure, blood glucose, serum lipid profile, urine acid (UA), fasting plasma insulin, serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, adiponectin, lipopolysaccharide (LPS), percentage and distribution of body fat were measured before and after treatment. Results (1) Data of scores of dampness-heat and diastolic blood pressure were significantly decreased after treatment in drug group. The above indexes and hip circumference were significantly decreased after the treatment in treatment group compared with those of control group ( P<0.05). (2) The triglyceride (TG), UA, insulin, HOMA-IR, LPS and IL-1βwere significantly decreased after the treatment in treatment group than those of control group, while there were no significant differences in fast blood glucose (FBG), 2 h postprandial plasma glucose (2 hPG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), TNF-α, IL-6 and adiponectin between two groups. (3) The percentage of visceral fat was significantly decreased in treatment group than that of control group. There were no significant differences in fat changes of limbs and buttocks between two groups. Conclusion Shanzha Xiaozhi capsule can decrease body weight and visceral fat content, reduce insulin resistance, and improve chronic inflammation state in obese patients with dampness- heat constitution.

Objective To investigate the effect of Shanzha Xiaozhi Capsules (SXC) on body weight, metabolic indexes, body fat accumulation and distribution of obesity patients with phlegm-dampness constitution. Methods Fifty obesity patients with phlegm-dampness constitution were randomized into control group and medicine group, 25 cases in each group. The control group was given lifestyle instructions for diet and exercises, and the medicine group was treated with SXC orally besides the instructions for lifestyle. The treatment for both groups covered 12 weeks. Before and after treatment, we observed the outcomes including scores of phlegm-dampness, body weight, waist circumference, hip circumference, blood pressure, fasting blood glucose, serum lipid profile, urine acid, body fat accumulation and distribution, and visceral fat accumulation. Results(1) The scores of phlegm-dampness were decreased significantly in both groups after treatment (P<0.05 or P<0.01), and the decrease was obvious in the medicine group(P<0.01).(2) Body weight and BMI were decreased significantly in both groups after treatment(P<0.01), and the decrease was obvious in the medicine group(P<0.05). Waist circumference was decreased significantly in the medicine group(P <0.05) but stayed unchanged in the control group(P>0.05). Hip circumference was decreased significantly in both groups(P <0.05 or P<0.01) , but the difference between the two groups was insignificant(P>0.05).(3) Systolic pressure and diastolic pressure were decreased significantly in both groups (P<0.01). But the difference of blood pressure decrease between the two groups was insignificant(P > 0.05).(4) Fasting blood glucose, 2-hour blood glucose after oral glucose tolerance test, serum lipid profile and urine acid remained unchanged in both groups after treatment (P>0.05). (5) The general body fat accumulation of both groups was decreased significantly after treatment (P <0.05 or P<0.01), and the decrease was obvious in the medicine group(P<0.01). Body fat accumulation in legs, trunk and gynoid region were decreased significantly in both groups after treatment(P<0.05 or P<0.01), but the difference of fat accumulation decrease between the two groups was insignificant(P>0.05). Waist fat accumulation had no significant decrease in the control group (P > 0 . 05), but was decreased in the medicine group (P<0.01). Visceral fat accumulation was decreased significantly in both groups after treatment(P<0.01), and the decrease was obvious in the medicine group (P<0.01). Conclusion In addition to its contribution to body weight loss, SXC also contribute to the reduction of visceral fat accumulation in obesity patients with phlegm-dampness constitution .

At present medical disputes still happen sometimes though governments at all levels, health departments and hospitals pay more and more attention to correctly guide patient's behavior, regulate doctor's behavior in diagnosis and treatment, purify therapeutic environment, strengthen legislation and protect the legitimate rights and interests of doctors and patients. The causes of medical disputes are great many, and the fundamental reason is that the medical behavior from the beginning to the end is related to the life and health, naturally accompanying medical risk and hiding dispute, therefore what we ought to do is not to absolutely eliminate the risk, but to reduce the risks and disputes. In this report, to explore the causes of medical disputes and risks and look for ways to reduce them, the survey of questionnaires was carried out and practical cases of medical disputes were analyzed in hospitals. Seventy-seven cases of medical disputes from 2013 to 2015 had been completed by arbitration or court decisions, and the final arbitral ideas were as follows: invalid doctor-patient communication, low technology and insufficient management were the main causes of medical disputes; the survey of 483 questionnaires on doctors and nurses in the hospital showed that in addition to the above 3 reasons, there were other deep reasons, namely heavy working intensity, low quality of patients or their family members, and the insufficient management runs through all the links in the way. Therefore, to reduce medical disputes, the following aspects should be commenced: effective communication between doctors and patients; improving doctors' clinical diagnosis and treatment ability; optimizing medical management; correcting medical work attitude;timely medical consultation; attaching importance to medical records; doctor's order leaving some leeway or allowing for unpredictable circumstances; constructing healthy hospital culture; paying attention to the physical and mental health of medical staff; actively improving the medical dispute settlement mechanism and related legal system construction.

Objective To observe the changes in serum a proliferation inducing ligand(a proliferation inducing ligand,APRIL)and N-myc downstream regulated gene 1(N-myc downstream regulated gene 1,NDRG1)levels,and analyze their diagnostic value for ovarian endometrioma(OEM).Methods From July 2021 to July 2022,132 patients with OEM who visited Zigong First People's Hospital were regarded as the observation group,and regular follow-up was conducted.According to the prognosis of these patients,they were grouped into the recurrence group(n=50)and the non recurrence group(n=82).Meanwhile,78 healthy individuals who had their medical checkups at the hospital during the same period were the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum APRIL and NDRG1 levels,and the general data of the recurrent and non recurrent groups were compared.Logistic regression analysis was applied to analyze the relevant factors affecting the prognosis of OEM.Pearson analysis was applied to explore the correlation between serum APRIL and NDRG1 levels in patients with OEM.Receiver operating characteristic(ROC)curve was applied to evaluate the diagnostic value of serum APRIL,NDRG1 levels and their combination for OEM.Results Compared with the control group,APRIL level(35.28±6.81ng/ml vs 26.37±3.19ng/ml)and NDRG1 level(124.39±15.67μg/L vs 9.67±10.82μg/L)in observation group were increased,and the differences were significant(t=10.864,17.278,all P<0.05).Compared with the non recurrence group,the serum levels of APRIL(40.38±7.88ng/ml vs 32.16±6.18ng/ml)and NDRG1(132.04±19.83μg/L vs 119.73±13.16μg/L)in the recurrence group were increased,and the differences were significant(t=6.668,4.287,all P<0.05).Logistic regression analysis showed that serum APRIL and NDRG1 levels were risk factors for the prognosis of patients with OEM(Waldχ2=11.839,28.437,all P＜0.001).Pearson method analysis results showed a positive correlation between serum APRIL level and NDRG1 level in patients with OEM(r=0.439,P<0.001).The area under the curve(AUC)of combined diagnosis of serum APRIL and NDRG1 levels in patients with OEM was 0.849,with a sensitivity and specificity of 73.95%and 85.37%,respectively,which was better than the single prediction of APRIL and NDRG1(Z =2.644,2.094,P=0.008,0.036).Conclusion The serum levels of APRIL and NDRG1 were increased in patients with OEM.The combination of the two has high clinical value in the diagnosis of OEM,which may be closely related to the prognosis of patients with OEM.

Objective To provide objective parameters for differentiating pancreatic cystic tumors via using computed tomography texture analysis (CTTA) to quantify the special imaging features of pancreatic cystadenomas.Methods Enhanced CT images of pancreas from patients who were admitted in Department of Radiology in First Hospital affiliated with Zhejiang University and First People's Hospital of Hangzhou City and pathologically diagnosed as pancreatic serous cystadenomas (n =48) and mucinous cystadenomas (n =34) from January 2009 to December 2016 were retrospectively analyzed.Regions of interest were drawn on the parenchymal phase CT images in 5 slices according to the border of the tumors.Mean grey level intensity (M),variance (V),entropy (E),skewness (Ske) and kurtosis (Kur) were obtained from fine texture (σ =1.0) to coarse texture (σ =2.5).Receiver operating characteristic (ROC) curve for texture parameters with statistically difference was drawn,and the area under curve (AUC),diagnostic sensitivity and specificity were calculated.The diagnostic accuracy of senior and junior doctors was compared with the traditional CT analysis method.Results Reliability coefficient of the two radiologists was 0.809 ～ 0.997 with high consistency.Compared with mucinous cystic tumors,serous cystadenomas had a significantly different V (5.93 ± 9.02 vs 1.29±0.62),E (2.39±0.61 vs2.02±0.39) and Kur(30.18 ±42.55 vs 8.80-±4.34) in Ske0 of 2.5 (P ＜0.05),and there were no statistically significant differences on other parameters.The AUC of differential parameters for diagnosing two kinds of cystic tumors ranged from 0.56 to 0.84.The diagnostic accuracy of the traditional CT analysis method by junior doctor and senior radiologist was 60％ and 71％,respectively.Conclusions CTTA can not only effectively quantify the heterogeneity of pancreatic cystadenomas,but also is effective in the differentiation.

OBJECTIVE: To investigate the persistent damage of learning and memory ability after the cessation of sub-chronic manganese(Mn)-exposure in rats. METHODS: Specific pathogen free weaning male SD rats were randomly divided into control group and low-, medium-and high-dose groups based on body weight, with 6 rats in each group. Rats were intraperitoneally injected with Mn chloride(MnCl_2·4 H_2O) at the concentrations of 0, 5, 10, or 20 mg/kg body weight, 5 days per week for 6 weeks and continued to be observed for 12 weeks after the cessation of Mn-exposure. During the experiment, the body mass of the rats was weighed. Learning and memory ability was evaluated by a Morris water-maze task at the 6 th weeks of Mn-exposure(cessation of Mn-exposure of week 0), the 6 th and 12 th week of the cessation of Mn-exposure. The organ coefficients of heart, liver, spleen, kidney and testicles were evaluated after the cessation of Mn-exposure on week 12. RESULTS: The body mass of the high-dose group was lower than that of the other 3 groups(P<0.05) at the 4 th and 6 th week of Mn-exposure and the 2 nd week of the cessation of Mn-exposure. There was no significant difference in body mass between the groups(P>0.05) on the 12 th week of the cessation of Mn-exposure. The escape latency of high-dose group was higher than that of the control group(P<0.05), and the number of platform crossings in the low-, medium-and high-dose groups were fewer than that in the control group(P<0.05) after the cessation of Mn-exposure. The escape latency was shorter and the numbers of platform crossings were higher on the 6 th and 12 th week of the cessation of Mn-exposure(P<0.05) when compared with that of the 6 th week of Mn-exposure rats. There was no statistical significance in the organ coefficients of heart, liver, spleen, kidney and testicles among the 4 groups at the 12 th week of the cessation of Mn-exposure in rats(P>0.05).CONCLUSION: Sub-chronic Mn exposure can impair learning and memory ability of rats, and the damage persists after the cessation of Mn-exposure.

Spatiotemporal scanning analysis detected two high concentration areas, mainly concentrated in Gannan Tibetan Autonomous Prefecture. Conclusion Syphilis in Gansu Province has regional differences in space, and high-high accumulation areas in Gannan Tibetan Autonomous Prefecture persist, and targeted prevention and control strategies should be specified according to temporal and spatial characteristics.

BACKGROUND: This study aimed to develop a comprehensive instrument for evaluating and ranking clinical practice guidelines, named Scientific, Transparent and Applicable Rankings tool (STAR), and test its reliability, validity, and usability. METHODS: This study set up a multidisciplinary working group including guideline methodologists, statisticians, journal editors, clinicians, and other experts. Scoping review, Delphi methods, and hierarchical analysis were used to develop the STAR tool. We evaluated the instrument's intrinsic and interrater reliability, content and criterion validity, and usability. RESULTS: STAR contained 39 items grouped into 11 domains. The mean intrinsic reliability of the domains, indicated by Cronbach's α coefficient, was 0.588 (95% confidence interval [CI]: 0.414, 0.762). Interrater reliability as assessed with Cohen's kappa coefficient was 0.774 (95% CI: 0.740, 0.807) for methodological evaluators and 0.618 (95% CI: 0.587, 0.648) for clinical evaluators. The overall content validity index was 0.905. Pearson's r correlation for criterion validity was 0.885 (95% CI: 0.804, 0.932). The mean usability score of the items was 4.6 and the median time spent to evaluate each guideline was 20 min. CONCLUSION The instrument performed well in terms of reliability, validity, and efficiency, and can be used for comprehensively evaluating and ranking guidelines.
