Objective To study the role of chronic prostatitis(CP)in the pathogenesis and development of IgA nephropathy(IgAN). Methods The incidence rate of CP was compared between the patients with IgAN and the patients with non-IgA mesangial proliferative glomerulonephritis. Furthermore, the clinical and pathological features were compared between the IgAN patients without CP and those with CP. The therapeutic effect of anti-inflammatory treatment in IgAN patients with CP was evaluated. Results Incidence of CP in IgAN patients was 44.7% and that in non-IgA mesangial proliferative glomerulonephritis patients was 21.6%. There was significant difference in the incidence of chronic prostatitis between the two groups. The incidence of glomerular sclerosis and the deposition of immune complexes in vascular wall in IgAN patients with CP were higher than that in patients without CP. The treatment of CP may be beneficial in ameliorating IgAN in some patients. Conclusion Chronic prostatitis is one of the probable pathogenetic factors in IgAN.

Objective To survey the scientific research integrity situation of community health care organizations in Yangpu district in Shanghai,meanwhile,provide a reference for scientific research integrity management in any community health care organization.Methods Using the convenience sampling method,we sampled 200 health staff from 4 community health service centers.They were surveyed with uniform questionnaires.Results No dramatically relationship existed in health staff's knowledge about scientific research integrity breach and their age.However,education background,their academic titles,how many times they have learned relative information,publicity about science research integrity would impact their awareness on research integrity.Conclusions There is dramatically discrepancy on the scientific research integrity among these community health staff.

Objective:To evaluate the effectiveness of contrast-enhanced ultrasound in the differential diagnosis of atypical adenomyosis and fibroids using a decision tree model.Methods:The data of cases with difficulty in differentiating atypical adenomyosis from fibroids on conventional ultrasound examination at Shengjing Hospital of China Medical University from April 2021 to April 2022 were selected and analyzed. Ninety-five patients with contrast-enhanced ultrasound examination were finally selected, including 64 patients in the pathologically confirmed adenomyosis group and 31 patients in the fibroids group. The data from the qualitative analysis and the quantitative analysis of the time-intensity curve (TIC) curve were collected separately, including the temporal variability of contrast entry into the lesion, i.e.the difference between the time when the contrast agent started to enter the lesion and the time when the contrast agent finally filled the lesion completely. Indicators were first screened for inclusion in the decision tree model by univariate and multifactorial analyses, and decision tree models based on qualitative analysis indicators, and qualitative and TIC-based analyses were developed to further assess the diagnostic efficacy of both models.Results:Through the univariate analysis, it showed that the qualitative analysis indicators of lesion onset enhancement pattern, enhancement intensity, intra-lesion contrast distribution, and post-contrast lesion border were of statistical significance (all P<0.05) between the two groups. The differences in contrast arrive time (AT), contrast time to peak (TTP), |ΔAT|, and |ΔTTP| in the TIC curve analysis indexes were statistically significant between the two groups (all P<0.05). The difference in lesion temporal phase variability was statistically significant between the two groups ( P<0.05). After further screening by multifactorial analysis, the accuracy and misdiagnosis rates were 87.40% and (17.90±3.90)% in the qualitative analysis-based decision tree model respectively, and 90.50% and (21.10±4.20) % in the qualitative and TIC curve-based analysis decision tree model respectively. The ROC curves were plotted according to the two groups of models, and the areas under the curves were 0.915 and 0.931 respectively. Conclusions:A decision tree model based on ultrasonographic image analysis has diagnostic value for the differential diagnosis of atypical adenomyosis and uterine fibroids.

Pulmonary arterial hypertension is a clinical syndrome characterized by pulmonary vascular remodeling causing increased vascular resistance, which will lead to right heart failure and even death if left untreated. The pathogenesis of pulmonary arterial hypertension has not yet been clarified, and clinical treatments have not been effective in improving prognosis or reducing mortality. To investigate the pathogenesis of pulmonary arterial hypertension and to develop and evaluate more effective and safer drug treatments, establishing related animal disease models is very important. This paper outlines the pathological characteristics of pulmonary arterial hypertension and summarizes the various types of animal models of pulmonary arterial hypertension, as well as describes the progress of the application of these models in three therapeutic pathways and related drug research in the past five years, with a view to providing a reference for the selection of animal models of pulmonary arterial hypertension and research applications.

Chronic liver disease （CLD） tends to have a high incidence rate and impose a serious burden on society and families. Studies have shown that metal ion metabolism is closely associated with CLD， and some Chinese herbal medicines can play a role in the prevention and treatment of CLD by regulating metal ion metabolism. At present， the synthetic drugs currently used for the treatment of CLD fail to achieve a satisfactory effect， and therefore， a variety of Chinese herbal medicines are being used as supplementary and alternative therapies for CLD. This article introduces the role of metal ion metabolism in CLD and the regulatory effect of Chinese herbal medicines and their active components on CLD， and the analysis shows that metal ion metabolism is expected to provide new ideas for the research on CLD and a theoretical basis for the clinical treatment of CLD. For the role of metal ion metabolism in the treatment of CLD， more prospective clinical study data are needed in the future to provide effective and safe treatment regimens for patients with CLD.

Trillions of microbes reside in the human body and participate in multiple physiological and pathophysiological processes that affect host health throughout the life cycle. The microbiome is hallmarked by distinctive compositional and functional features across different life periods. Accumulating evidence has shown that microbes residing in the human body may play fundamental roles in infant development and the maturation of the immune system. Gut microbes are thought to be essential for the facilitation of infantile and childhood development and immunity by assisting in breaking down food substances to liberate nutrients, protecting against pathogens, stimulating or modulating the immune system, and exerting control over the hypothalamic-pituitary-adrenal axis. This review aims to summarize the current understanding of the colonization and development of the gut microbiota in early life, highlighting the recent findings regarding the role of intestinal microbes in pediatric diseases. Furthermore, we also discuss the microbiota-mediated therapeutics that can reconfigure bacterial communities to treat dysbiosis.
