Objective:To investigate the anti-fatigue effect of Dendrobium and Panax Quinquefolius Granules(DPQG)on the overtrained mice,and to clarify its possible mechanism.Methods:A total of 48 mice were randomly divided into control group(equal volume of distilled water),low dose of DPQG group(400 mg·kg-1 DPQG),medium dose of DPQG group(800 mg·kg-1 DPQG),and high dose of DPQG group(1 600 mg·kg-1 DPQG).The DPQG were administered by gavage for 35 d,and the rotarod test and swimming endurance test were performed 30 min after last administration.Serum,liver tissue,and muscle tissue were collected from the mice in various groups.ELISA method was used to detect the serum lacticacid(LAC)levels and lactate dehydrogenase(LDH)activities,and the malondialdehyde(MDA)levels,superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)activities,and the liver glycogen and muscle glycogen levels in muscle tissue of the mice in various groups;HE staining was used to observe the pathomorphology of muscle tissue of the mice.Transcriptomics and metabolomics technologies were used to identify the key genes and metabolites in muscle tissue of the mice in control group and high dose of DPQG group and to analyze the correlations between differentially expressed genes(DEGs)and differentially expressed metabolites.Results:Compared with control group,the rod turning exhaustion time of the mice in different doses of DPQG groups were significantly increased(P＜0.05),and the swimming exhaution time of the mice in high dose of DPQG group was increased(P＜0.05).Compared with control group,the LDH,SOD,and GSH-Px activities of the mice in medium and high doses of DPQG groups were increased(P＜0.01).Compared with control group,the levels of MDA and liver glycogen of the mice in medium and high doses of DPQG groups were decreased(P＜0.05 or P＜0.01).The transcriptomics sequencing results showed that DPQG mainly acted on DEGs such as Trib3 and Olfr495;the Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis results showed that the DEGs were mainly enriched in olfactory-related processes and signaling pathways;the metabolomics KEGG analysis results showed that the differential metabolites were mainly enriched in the regulation pathway of inflammatory mediators on tryptophan(TRP);the combined analysis of transcriptomics and metabolomics results showed that the piezo1 gene had high correlations with the differential metabolites β1-solamarine(r=-1,P＜0.05)and tilidine(r=1,P＜0.05).Conclusion:DPQG can exert an anti-fatigue effect on the overtrained mice by modulating LAC metabolism and glycogen homeostasis,as well as maintaining the oxidative/antioxidant balance in the body;its anti-fatigue mechanism is related to the Olfr495 and piezo1 genes and the regulation pathway of inflammatory mediators on TRP channels.

Objective:To explore a definition of healthy longevity in the Chinese population based on the Delphi method.Methods:Through a comprehensive literature review and expert consultation, the dimensions in the definition of healthy longevity were identified, and a preliminary list of questions was created. Experts in clinical medicine, public health, basic research, and the elderly care service industry, who had been working in the field of geriatric health for at least 5 years, were invited to participate in the Delphi survey from August to December 2022. The survey questionnaires were administered via email in two rounds, and experts were asked to select the optimal options from the provided questions. The active coefficients were expressed by the response rate, and a consensus was reached when the largest number of experts agreed for single-choice questions and more than 70% agreed for multiple-choice questions.Results:In the two rounds, the active coefficients were 96.00% (24/25) and 79.17% (19/24), respectively, and a consensus was finally reached on nine items, including age, physical health, common metabolic indicators, mental health, cognitive function, functional ability, social activity, self-rated health, and subjective well-being. Following discussions among the research team and experts, a final definition of healthy longevity was determined. Healthy longevity could refer to a state of good physical, psychological, cognitive function and social adaptation, as well as subjective well-being, in individuals aged 90 and above. Specifically, individuals with healthy longevity should be free from diseases associated with high disability rates and mortality, such as stroke, cancer, and Parkinson′s disease. They should also maintain reasonable levels of common non-communicable disease indicators, such as blood pressure and blood glucose, and exhibit favorable mental health and cognitive function using validated measurement tools. In addition, individuals with healthy longevity should engage in social interactions with friends and relatives, care for family members, and go out to do things. Meanwhile, with the ability to complete the visual and hearing functions of daily life and communication, and the ability to complete basic activities such as walking, eating, bathing, toileting, dressing, continence of urination, and bowel movement independently, they could rate themselves to be in good health and experience a relatively high level of life satisfaction.Conclusion:A definition of healthy longevity in the Chinese population is established through the two-round Delphi consultation.

Objective:To investigate the prognosis and risk factors of IgA vasculitis nephritis (IgAVN) in children.Methods:A retrospective cohort study was conducted. Clinical data were collected from 264 children who were pathologically diagnosed with IgAVN at Department of Pediatric Nephrology, Tongji Hospital, affiliated with Tongji Medical College, Huazhong University of Science and Technology, between January 2011 and December 2017. All patients had a follow-up period of more than 3 years. Clinical characteristics, renal pathology, 3-year and 5-year prognosis were analyzed. The patients were grouped based on gender, age of onset (≤6 years, >6-9 years, and >9 years), pathological classification (≤Ⅲ and>Ⅲ),whether the prognosis was complete remission at 3 and 5 years. Independent sample t-tests, ANOVA or chi-squared test were used for intergroup comparisons. Spearman correlation analysis was applied for ordinal data, and multivariate Logistic regression was used to analyze factors affecting the prognosis. Receiver operating characteristic (ROC) curve was utilized to evaluate the predictive value of these factors. Results:Of the 264 children with IgAVN, 153 were male and 111 were female, the age of onset was 8.3 (6.7, 10.3) years, 118 patients (45%) with onset age >6-9 years accounted for the highest proportion. All patients presented with skin purpura and renal involvement, primarily manifesting as hematuria and/or proteinuria. Microscopic hematuria was observed in 253 patients (95.8%), while 246 patients (93.2%) showed proteinuria. In 256 patients (97.0%), hematuria or proteinuria urinalysis was detected within 6 months of skin purpura onset, and 243 patients (92.0%) underwent renal biopsy within 6 months of renal involvement. The most common clinical subtype in 264 IgAVN children was hematuria and proteinuria (204 cases, 77.3%), with grade Ⅲ being the predominant pathological classification (181 cases, 68.6%). Among children ≤6 years old, the 3-year complete remission rate was higher in males than in females (83.9% (26/31) vs. 7/16, χ2=8.12, P=0.012). Factors independently associated with poor 5-year prognosis included time from hematuria or proteinuria urinalysis to renal biopsy >6 months, elevated serum cholesterol levels, and incomplete remission 3 years post-biopsy ( OR=5.41, 1.39, 6.02, 95% CI 1.40-20.86, 1.04-1.84, 2.61-13.88, all P<0.05). The serum cholesterol has a predictive value for 5-year prognosis ( P=0.020, AUC=0.62, 95% CI 0.52-0.71, Youden index=0.27, cutoff=4.37). Conclusions:For children with IgAVN aged≤6 years, the 3-year prognosis is better in males than in females. Time from hematuria or proteinuria urinalysis to renal biopsy >6 months, elevated serum cholesterol levels, and incomplete remission at 3 years post-biopsy may be independent risk factors for poor 5-year prognosis in children with IgAVN.

Objective To establish a simple,rapid and sensitive nucleotide polymorphisms genotyping method in order to conduct the routine clinical detections under the simple laboratory condition by this method.Methods Based on the ligase-agarose gel electrophoresis,the oligonucleotide detection probes of mutational sites was designed.The detection underwent the detection probe connecting,purification and universal amplification,finally the mutation genotypes of detection sites were judged by the ap-peared bands in the agarose gel electrophoresis(AGE).With the 3 SNP sites EGFR,c.2573T>G(L858R),EGFR,c.2582T> A (L861Q)and EGFR,c.2155 G>T(G719C)in epidermal growth factor receptor(EGFR)gene as the detection objects,the plasmid template and plasma circulating DNA sample in lung cancer were performed the detection.Results The established method was easy to operate with higher specificity and sensitivity.After 20-30 cycles of PCR amplification,the genotype of detection sites was clearly estimated according to the amplification band.When detecting the mixed alleles in the heterogeneous sample,minimal 2.5%mutation alleles could be detected out.This method and the direct sequencing method could respectively detect 6 cases and 2 cases of heterozygotes mutation in the SNP site of L858R among 62 samples of lung cancer.Conclusion The established detection method for SNP genotyping is suitable to the routine mutation detection on the heterogeneous samples under the simple laboratory condi-tion.

ObjectiveTo investigate the application value of digital three-dimensional reconstruction in liver transplantation for hepatic alveolar echinocoecosis (HAE).MethodsClinical data of 21 patients with end-stage HAE undergoing liver transplantation (LT) and 6 living donors in the First Affiliated Hospital of Xinjiang Medical University between April 2012 and December 2014 were retrospectively studied. Among the 21 patients, 13 were males and 8 were females with the average age of (43±13) years old. Among the 6 donors, 4 were males and 2 were females with the average age of (40±9) years old. Fifteen cases underwent extracorporeal hepatectomy and autotransplantation and 6 cases underwent living donor LT. The informed consents of all patients and 6 living donors were obtained and the local ethical committee approval had been received. All patients and donors received computer tomography (CT) plain scan, 3-phase (arterial phase, portal venous phase and delayed phase) enhancement scan and computed tomography angiography (CTA). The total liver volume and the liver graft volume were measured according to the two-dimensional liver image. The digital three-dimensional liver reconstruction software was used to perform three-dimensional model reconstruction. The total liver volume and the liver graft volume were measured a second time. The liver section was designed and the individualized virtual surgery was performed. The actual total liver volume and the liver graft volume were measured during LT to assess the error rate of liver volume predicted before operation. The comparison of liver volume data was conducted usingt test and the comparison of the error rate of liver graft volume was conducted using Chi-square test.Results The intrahepatic anatomical relationship was clearly displayed by the three-dimensional model, which was in accordance with that observed during operation. The liver graft volume of 15 patients undergoing extracorporeal hepatectomy and autotransplantation and 6 patients undergoing living donor LT calculated by the digital three-dimensional reconstruction technology was (766±197) ml, which was signiifcantly smaller than (833±243) ml calculated by the two-dimensional measurement (t=-3.674,P<0.05). Compared with the actual liver graft volume of (955±194) ml measured during operation, the average error rate of the liver graft volume calculated by the three-dimensional reconstruction technology was (6±1) %, which was signiifcantly smaller than (13±2) % of that calculated by two-dimensional measurement (t=-14.346,P<0.05). The liver graft volume measured by the three-dimensional measurement was positively correlated with the actual liver graft volume measured during operation (r=0.967,P<0.05). All the operations were completed successfully. One patient died of acute renal failure 12 d after LT. No case was observed developing liver failure or hemorrhage or other severe complications. The growth of the liver graft was good and the anastomotic stoma of intrahepatic vessels was clear by CT reexamination and three-dimensional reconstruction after operation. ConclusionThe application of three-dimensional reconstruction technology in preoperative assessment and operation planning of LT for end-stage HAE can improve the precision and success rate and achieve good curative effect.

Objectiye To investigate the value of liver transplantation for the treatment of end-stage hepatic alveolar echinococcosis(HAE).Methods The clinical data of 8 patients with end-stage HAE who received liver transplantation at the First Affiliated Hospital of Xinjiang Medical University from December 2000 to August 2010 were retrospectively analyzed.The operation time,anhepatic phase,infusion of suspension of red blood cells and postoperative complications were observed.Results The median operation time,anhepatic phase and infusion of suspension of red blood cells were 635 minutes(range,490-760 minutes),66 minutes(range,44-240 minutes)and 20 U(range,4-40 U).Liver transplantation was successfully carried out on 7 patients except for 1 patient who received emergent liver transplantation died of severe hepatic encephalopathy,renal failure and coagulation disorder on postoperative day 1.The median follow-up time was 6 months(range,3-29 months).One patient died of septicopyemia in postoperative month 3,1 died of incurable infection of bile duct in postoperative month 5,and 1 died of acute rejection in postoperative month 6.One patient was complicated with stricture of the bile duct anastomosis,and was cured by choledochojejunostomy.The size of the metastatic lesion in the left lung of 1 patient was reduced.One patient who underwent liver autotransplantation had no signs of residual liver disease with good liver function.Conclusion End-stage HAE is an indication for liver transplantation.A minimum dose of immunosuppressive agent and systemic administration of anti-HAE drugs are necessary to prevent the recurrence of HAE and ensure a long-term survival.Liver autotransplantation is the optimal method for the treatment of end-stage HAE,because no immunosuppressive agent is needed after operation.

Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.

Objective To evaluate the clinical applications and surgical methods of combined laparoscopic common bile duct (CBD) exploration with choledochoscopy. Methods From 2006 to 2009,clinical data of 42 patients with choledocholithiasis undergoing laparoscopic common bile duct exploration were retrospectively analyzed. We applied a step-by-step electric coagulating incision technique on the CBD,the step-by-step suturing technique, and the step-by-step clamping technique with alligator forceps, and soft tube irrigating technique with suctioning by selecting the proper exploration route, improving the common bile duct incision technique and calculus removing techniques. Results Procedures were successful in all the cases. There was no conversions to open surgery, no postoperative bleeding and no operative mortality. The mean operating time was 120 minutes (ranging, 90 to 150 minutes) with minimal intraoperative blood loss ( ranging, 20 to 40 ml). Ductal stone clearance was successful in 41 out of 42 patients ( 93% ). The largest number of the common bile duct stones was 16. With the diameter of stones larger than 15 mm in 18 cases in which the biggest was 30 mm. Bile leak developed in 1 patient, retained stones found in 3 patients,including intrahepatic cholelithiasis in one case. As a result, 38 out of 42 patients underwent common bile duct exploration. 35 patients were placed on T-tubes. Four patients underwent cystic duct exploration in which 3 had primary suture of the cystic duct and 1 had drainage. There was no infection and stenosis of biliary tract in the 42 followed-up cases. Conclusions Laparoscopic common bile duct exploration with stone extraction can be performed with high efficiency, minimal morbidity and without mortality. Improving the way of operation and selecting suitable exploration can result in better clinical outcomes.

Objective To evaluate the embolization efficiency,short term clinical effect and adverse reactions of trisacryl gelatin microspheres in interventional treatment of hepatic carcinoma. Methods Twenty three cases of hepatic carcinoma (34 foci)were given 0.5-6 ml of microspheres mixed with some contrast medium via catheter after injection of chemodrugs and lipiodol 3-5 ml; and simultaneously observing the appearance of slow down of blood flow and vascular cast formation to stop the procedure. Enhanced CT or MR and AFP were performed every 1 month after the first procedure. Treatment needed to be repeated whenever the foci or new ones were enhanced in CT scans or increase of AFP value. The clinical effect and adverse reactions were also observed. Results The positive response rate was 39.1% (CR+PR). There were 9 cases of PR,13 cases of NC and 1 of PD; but no case of CR. Residual enhancement was observed in 17 foci after first procedure,10 of which received repeated therapy and 3 were embolized completely. The other 11 foci were completely embolized,among them 4 had new residual enhancement during 4-9 mo follow up and 2 were re-embolized completely. Eighteen cases with positive AFP showed obvious decrease in 11,no change in 6 and increase in one. Eighteen cases of pyrexia,11 cases of pain in hepatic region and 6 cases of nausea occurred 5-14 d after the procedure together with vomiting. We also found increase of ALT in 2 cases,BIL of 1 case,and no change of WBC in all cases. Conclusion Trisacryl gelatin microspheres is an excellent embolization agent with better clinical effect and less adverse reaction in the treatment of hepatic carcinoma.
