Objective To investigate the exercise performance in maintenance dialysis patients,and analyze its correlative factors.Methods Maintenance dialysis patients admitted in Tongji Hospital of Shanghai from December 2014 to March 2015 were enrolled,with their baseline data and biochemical measurement being collected.The anthropometric indexes including arm circumference,triceps skinfold,waist circumference and hip circumference were detected.The exercise activity was assessed by hand grip test,timed up and go test (3mTUG) and five times sit-to-stand test (FTSST).Patients were divided into fast group (3mTUG≤12 s) and slow group (3mTUG ＞ 12 s).Univariate and multivariable analyses were used to evaluate the factors influencing exercise performance in maintenance dialysis.Results There were 121 patients enrolled:62 on peritoneal dialysis and 59 on hemodialysis,76 men and 45 women.Patients' average age was (61.6± 13.0) years and median dialysis age was 31.7(12.3,69.0) months.There was no statistical difference between fast group (n=80) and slow group (n=41) in gender,dialysis method,dialysis age,body mass index (BMI),arm muscle area (AMA),waist-hip ratio (WHR),hemoglobin (Hb) and total cholesterol (TC).Patients in fast group were younger,had higher serum albumin,prealbumin,serum phosphate and iPTH,and less prevalence of diabetes than those in slow group.In exercise activity,patients in fast group had better performance in handgrip,3mTUG and FTSST (all P ＜ 0.05).Univariate analysis showed that,handgrip was correlated with sex (male),AMA,BMI,age,diabetes,serum phosphorus and TC;scores in FTSST was correlated with age,BMI,diabetes,WHR,dialysis method,dialysis age,prealbumin and serum phosphorus;scores in 3mTUG was correlated with age,diabetes,WHR,dialysis method and dialysis age,prealbumin,serum phosphorus and iPTH (all P ＜ 0.05).Multiple stepwise regression analysis showed that sex (male),age,AMA and diabetes were independently correlated with handgrip in dialysis patients (all P ＜ 0.05);age,dialysis method,BMI and diabetes were independently correlated with scores in FTSST (all P ＜ 0.05);age,dialysis method,diabetes and WHR were independently correlated with scores in 3mTUG (all P ＜ 0.05).Conclusions The exercise performances of patients on maintenance dialysis are impaired.Age and diabetes are independent factor associated with the exercise performances of patients on maintenance dialysis.AMA is independently associated with upper limb movement,and dialysis method,BMI and WHR are independent factors associated with lower limb movement in dialysis patients.

Objective　To explore the possibility of using the retrovirus vector (RV) in the gene therapy of neonatal neuropathy and the expression properties of target genes in the brain. Methods　We combined human placenta alkaline phosphatase (hpAKP) cDNA obtained from plasmid DAP with RV pLXSN and transferred recombinant plasmid into packed cell line PT67 by the liposome entrapment method. We injected high-titer recombinant hpAKP-RV into the 1-day-old mouse brain, and then determined the hpAKP expression in the brain by hybridation in situ and the enzyme histological chemistry method as well as the type of expression cells by the immunological histological chemistry method. Results　The infected cells lay in the Ⅱ-Ⅴ stratum of the cerebral cortex, the nuclei of the brain stem, the Purkenje cell stratum of the cerebellum, the vascular wall, and the cerebral mater. The area of positive cells increased from the 1st to the 7th day after the injection, but was smaller on the 28th day than on the 7th day after the injection, part of those being GFAP(-). RV was not found harmful to the nervous system. Conclusions　RV can transfer target genes into the newborn mouse brain effectively, including neurons. Target genes express normally. It is likely that RV could be used in the gene therapy of neonatal neuropathy.

Objective:To investigate the effect of rapamycin on cell growth and migration of gallbladder cancer GBC-SD cells, and to discuss its potential in clinical therapy of gallbladder cancer. Methods: Proliferation of GBC-SD cells treated with different concentrations of rapamycin (12.5, 25, and 50 mmol/L) was examined by MTT assay. Cell cycle distribu-tion and apoptosis of GBC-SD cells treated with different concentrations of rapamycin were determined by flow cytometry. Migration ability of GBC-SD cells was assessed by Transwell assay. The expression of mTOR (mammalian target of rapam-ycin) and its phosphorylation in GBC-SD cells were examined by Western blotting assay. Results: Rapamycin significant-ly inhibited the phosphorylation of roTOR, but had no influence on the expression of roTOR in GBC-SD cells. Rapamycin significantly inhibited the growth of GBC-SD cells in a dose-dependent manner (P < 0.01). Raparnycin induced apoptosis of GBC-SD cells and arrested them at the G_1/S phase. Furthermore, rapamycin also significantly suppressed migration of GBC-SD cells as showed by Transwell assay (P < 0.01). Conclusion: Rapamycin can remarkably inhibit the growth and migration of gallbladder cancer cells, probably by inhibition of p-roTOR pathway, induction of apoptosis and cell cycle ar-rest of gallbladder cancer cells.

OBJECTIVETo reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.

METHODSSAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

RESULTSCompared with the control group, acupuncture increased 39 transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice, of them, 14 belonged to ionophorous protein, 8 to G protein, 8 to transmembrane signal receptor, and 9 to kinase protein. Totally 3 main cell signal pathways were involved, including G-protein-coupled receptors signal, enzyme linked receptor signal, and ion-channel mediated signal. Compared with the sham-acupuncture group, acupuncture resulted in significant increase of kinase signal protein amount. From the aspect of functions, they were dominant in regulating synapse functions relevant to cytoskeleton and secreting neurotransmitters.

CONCLUSIONThe cell biological mechanism for treating AD by acupuncture might be achieved by improving synapse functions and promoting the secretion of neurotransmitters through transmembrane signal transduction, thus improving cognitive function of AD patients.
