BACKGROUND:Type 2 diabetes mellitus impairs renal function,and studies have shown that exercise interventions can protect the kidneys.Irisin can protect renal function in diabetic nephropathy patients by restoring autophagy through inhibition of the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway. OBJECTIVE:To explore whether exercise can restore autophagy and ameliorate renal injury by inhibiting over-activation of the renal PI3K/Akt/mTOR signaling pathway,as well as to analyze the differences in the effects of different modalities of exercise. METHODS:Six-week-old Sprague-Dawley rats were randomly divided into a blank control group(normal rats)and a diabetic group,and then the diabetic group was randomly divided into a diabetic model group,a moderate-intensity continuous exercise group,and a high-intensity intermittent exercise group after successful modeling using high-fat,high-sugar feeding plus intraperitoneal administration of low-dose 1%streptozotocin(30 mg/kg).The two exercise groups were subjected to 8 weeks of exercise intervention with different exercise intensities.The fasting blood glucose concentration was detected by glucose oxidase method,glycated hemoglobin levels was measured using a kit,serum insulin concentration was detected by Elisa method,and insulin resistance index was calculated.Gene expression of PI3K,AKT,mTOR,Beclin-1,podocin,and nephrin was detected by RT-PCR.Protein expression of mTOR and autophagy marker proteins LC3-1,LC3-2,and Beclin-1 was detected by western blot RESULTS AND CONCLUSION:Fasting blood glucose and glycosylated hemoglobin levels were highly significantly increased,insulin resistance levels were significantly increased,and insulin levels were significantly decreased in type 2 diabetic rats.Both exercises resulted in highly significant decreases in fasting blood glucose and glycosylated hemoglobin levels,significant decreases in insulin resistance levels and significant increases in insulin levels in type 2 diabetic rats.Insulin levels were significantly higher in the high-intensity intermittent exercise group compared with the moderate-intensity continuous exercise group.The expression of podocin and nephrind genes was significantly reduced in type 2 diabetic rats and two different forms of exercise significantly the gene expression.There was a further trend toward an increase in gene expression of podocyte-associated proteins in the moderate-intensity continuous exercise group compared with the high-intensity intermittent exercise group,but there was no significant difference.The mRNA and protein expression of PI3K,AKT and mTORC1 in kidney tissues of type 2 diabetic rats were significantly increased,and the expression of autophagy marker proteins Beclin-1 and LC3-2 and LC3-2/LC3-1 were significantly decreased.Both different forms of exercise significantly decreased the mRNA and protein expression of PI3K,AKT,and mTORC1,and significantly increased the autophagy marker proteins Beclin-1,LC3-2,and LC3-2/LC3-1 in renal tissues.Compared with the moderate-intensity continuous exercise group,there was a trend toward further decreases in mRNA expression of PI3K,AKT,and mTORC1 and protein expression of mTOR,and a trend toward further elevation of Beclin-1,LC3-2,and LC3-2/LC3-1 in the high-intensity intermittent exercise group,but only Beclin-1 showed a significant difference between groups.In summary,renal podocyte injury in type 2 diabetes mellitus with suppressed autophagy is closely related to aberrant activation of the PI3K/AKT/mTORC1 signaling pathway.Both moderate-intensity continuous exercise and high-intensity intermittent exercise can protect the diabetic kidney,reduce podocyte damage,and restore renal podocyte autophagy,which may be achieved by inhibiting the excessive activation of the PI3K/AKT/mTOR signaling pathway.High-intensity intermittent exercise shows a trend toward more favorable restoration of autophagy compared with moderate-intensity continuous exercise,but with a slight decrease in podocyte protein expression.

Objective:To analyze the genetic and molecular characteristics of H9N2 subtype avian influenza viruses from external environment and humans in Anhui Province from 2013 to 2022.Methods:Environmental samples and human samples were collected from Anhui influenza surveillance network laboratory. Sixty-three strains of virus were isolated in chicken embryos. RT-PCR was used to amplify the virus and whole genome sequencing was performed. To construct gene evolutionary tree and analyze its genetic characteristics and potential glycosylation sites.Results:The hemagglutinin (HA) gene belongs to the 9.2.4.5 clade, and the protein cleavage sites are mostly " PSRSSR\GL". The neuraminidase (NA) gene, basic protein-1(PB1) gene, acidic protein (PA) gene, non-structural protein (NS) gene and nucleoprotein (NP) gene belong to the F/98 clade, the matrix protein (MP) gene belongs to the G1/97 clade, and the basic protein-2 (PB2) gene belongs to the ST/7488 clade. Mutations of T155N, R164Q, H183N, T189D/V, A190V/T and Q226L occurred in HA protein, deletion of NA protein occurred at 62-64 sites, and mutations of T271A, I292V/M and E627V/L occurred in PB2 protein. At the same time, mutations of K356R and S409N occurred in the PA protein.Conclusions:The H9N2 subtype avian influenza viruses collected from external environment and human sources in Anhui province from 2013 to 2022 belong to the same evolutionary branch, and amino acid site mutations suggest that the virus shows a tendency to gradually adapt to the mammalian host environment. Therefore, further studies on the adaptive evolution of the virus and related monitoring work are needed.

It is of great significance to construct an information platform for performance appraisal of tertiary public hospitals to realize real-time monitoring and intervention of appraisal indicators, which is conducive to the transmission of responsibility for index optimization to departments and medical groups, and to promote the fine management of hospitals and promote high-quality development.This paper introduced the practice and effect of building a performance appraisal information platform for tertiary public hospitals in four aspects: accurate data filling, timely dynamic monitoring, visual display and safety management since 2022. At the same time, suggestions were put forward for platform optimization from four aspects: data quality control, co-construction and sharing, promotion and application, and system integration, in order to provide reference for other hospitals.

Objective To explore the strategy of intrathoracic anastomosis in patients with esophageal squamous cell carcinoma when the proximal esophagus is dilated to different degrees and explore its mechanism. Methods We retrospectively reviewed the clinical data of patients who underwent esophagectomy between 2014 and 2017 in West China Hospital. The patients were divided into two groups including a significant dilatation group with inner mucosal phase diameter (IMPD)≥17.9 mm and a non-significant dilatation group with IMPD<17.9 mm. And the patients were divided into two groups (a layered manual anastomosis group and a stapled anastomosis group) according to anastomosis method and propensity score matching was applied to adjust for potential confounders. Results We finally included 654 patients. There were 206 patients with 158 males and 48 females at average age of 62.21±7.72 years in the layerd manual analstomosis group and 448 patietns with 377 males and 71 females at average age of 62.57±8.42 years in the stapled anastomosis group. We also used Masson trichrome staining to assess the collagen fiber content in the esophagus. Compared with layered manual anastomosis, the incidence of anastomotic leakage was higher in the significant dilatation group than that in the stapled anastomosis group (original cohort: 3.8% vs. 10.7%, P=0.093; propensity score-matched cohort: 1.4% vs. 15.3%, P=0.004). And there was no significant difference in anastomotic leakage b etween layered manual anastomosis and stapled anastomosis in the non-significant dilatation group (original cohort: 4.7% vs. 4.2%, P=0.830; propensity score-matched cohort: 4.8% vs. 4.0%, P=0.206). Moreover, the average collagen fiber area ratio was significantly lower in the significant dilation group than that in the non-significant dilatation group (P=0.045). Conclusion There is a significant reduction in collagen fibers in the proximal esophageal wall tissue of esophageal squamous cell carcinoma patients with a IMPD≥17.9 mm. Intrathoracic layered manual anastomosis effectively reduces postoperative anastomotic leakage in these patients.
