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 investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P<0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P<0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

To investigate the recent prevalence and molecular epidemiological characteristics of por-cine diarrhea viruses in Sichuan Province,this study used fluorescence quantitative PCR to detect porcine diarrhea samples from multiple regions in Sichuan Province from 2021 to 2023.RT-PCR was used to identify the genotypes of PEDV,PoRVA,PDCoV,and PTV,and their genetic variabil-ity,evolutionary characteristics,and recombination events were analyzed.The results showed that PEDV,PoRVA,PDCoV,and PTV were still prevalent in Sichuan region,with overall positive rates of 14.2%(40/281),13.2%(37/281),15.6%(44/281),and 12.5%(35/281),respectively.PEDV mixed infection with other pathogens was the most common.This study obtained a total of six strains of G2b PEDV,three strains of G3 PDCoV,three strains of G9P[13]PoRVA,one strain of G3P[13]PoRVA,three strains of Type 5 PTV,and one strain of Type 9 PTV.Compared to the seven vaccine strains including CV777,DR13,KPEDV-9,Chinju99,KNU-0801,AJ1102,and LW/L,the 6 PEDV strains showed multiple amino acid mutation sites in the COE region and S1D epitope region.Among them,the strains PSCLZ01 and PSCMY04 formed a separate branch in the phylogenetic tree.The three PDCoV strains have a closer genetic evolution distance to the previ-ously prevalent strains in Sichuan,but they also have 6-48 amino acid mutations compared to them.The four PoRVA strains have 104-108 amino acid variations in the VP4 gene compared to the early vaccine strain LLR,and they have 25 common amino acid variations in the VP7 gene.From the phylogenetic tree,the VP7 gene of RSCMY01/G3P[13]belongs to the same branch as the Heilongjiang strain LNCY,but its VP4 gene clusters with the Sichuan strain SCYA-C7,indica-ting that this PoRVA strain may have undergone genetic reassortment during inter-provincial transmission between different genotypes.It is worth noting that in the detected samples of PTV-5 and PTV-9,other diarrheal viruses tested negative,indicating that these two genotypes of PTV may be important pathogens causing porcine diarrhea.Additionally,the S gene of PEDV PSCLZ01 strain and PDCoV PCSCMY02 strain have undergone recombination events,and their parental strains come from different regions,both domestic and international.These findings reveal the main types of porcine diarrheal viruses,as well as their genetic diversity and variations in Sichuan Province in recent years.This study enriches the molecular epidemiological data of porcine diarrhe-al pathogens in the region and provides an important theoretical basis for the prevention,control,and purification of porcine diarrhea in the local area.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).
