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 investigate the relationship between NF-?B activation and the expression of metastasis correlation factors.Methods The expression of NF-?B,COX-2,ICAM-1,VCAM-1 and MMP9 in colorectal cancer and normal tissues was detected using Western blotting.Results(1)The expression level of NF-?B was higher in cancer tissues than that in normal tissues(P

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.

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.

Objective To investigate the relevance between expectations before treatment, new symptoms and satisfaction after treatment of the pelvic organ prolapse (POP) patients. Methods Made a collection of 75 cases of POP patients at Peking University Third Hospital, who were affected by the POP symptoms and came to our clinic for treatment from January to December in 2013. Prospectively investigate the patients′expectations before treatment, which were the most troubling symptoms to be solved. According to treatment we divided the patients into surgery and pessary groups. Two groups were followed up with the degree to achieve the desired goals using patient global impression of improvement (PGI-I), new symptoms and satisfaction after treatment, try to find the relevance between expectations before treatment, new symptoms and satisfaction after treatment. Results There were 47 (63%, 47/75) patients in the surgical group and 28 (37%, 28/75) patients in the pessary group. The top three problems for patients were friction when walking (25%, 19/75), dysuria (23%, 17/75) and the feeling of vaginal prolapse (19%, 14/75). The follow-up rate was of 93% (70/75), follow-up time was (5 ± 4) months. Satisfaction score after treatment of surgical group was higher than that of pessary group [(4.9±0.4) versus (4.0±1.3) scores, P<0.01]. There was no statistically significant difference between two groups of PGI-I score [(6.7±0.6) versus (6.6±0.9) scores, P=0.886]. The top three new symptoms after treatment were increased secretion, urinary incontinence and dysuria. PGI-I and satisfaction scores was relevant (P=0.021). The availability of new symptoms and satisfaction scores was relevant (P=0.001). Conclusion When achieving higher expectations to the treatment and no more new symptoms, the satisfaction score after treatment is higher.

Objective To analyze the investigation results of an acute respiratory infection outbreak caused by adenovirus and provide scientific information for the prevention and control of congener public health emergencies .Methods A case‐control study was performed with grades and gender as matching factor ,all cases and selected controls were investigated with the same question‐naire .Results A totul of 47 cases were diagnosed in the outbreak ,no death ,the attack rate was 8 .88% ;the main clinical symptom was fever and 27 .7% of the cases became pneumonia .The case‐control study analysis demonstrated that with close contact to cases or not(χ2 =7 .96 ,P<0 .05) ,contact time (χ2 =7 .95 ,P<0 .05) ,hand washing habits (χ2 =25 .92 ,P<0 .05) and with or without the habit of cleaning snivel by hand directly (χ2 =22 .78 ,P<0 .05) were statistically different between cases and controls .Conclu‐sion long‐time contact to cases maybe the main risk factor for the adenovirus infection ,especially the contact manner were sharing the same desk or playing together .A good health habit of washing hands often and no cleaning snivel by hand directly were impor‐tant protective factors .Thus ,strengthening the training of health habit and awareness is the important preventive measure for re‐spiratory infectious diseases .
