OBJECTIVE To select the superior one from two skin-cleaning disinfection methods so as to reduce the possibility of hospital infection.METHODS The water plus soaps(control group) and Daniel disinfectants(test group) were used separately to clean and disinfect the skin of patients in intensive care unit(ICU).The degree of skin-cleaning of patients and hand pollution of nurses were observed and analyzed.RESULTS The number of bacteria on the skin of patients of the test group was remarkably lower than that of the control group with a statistically significant difference(t=7.94,P

Objective To assess the renal protective effects of triptolide treatment in type 2 diabetic rats and its possible mechanisms.Methods Wistar rats were randomized to receive following approach control (n=7),dia- betic model without treatment (n=7) and diabetic group treated with triptolide[200 ?g/(kg?d),n=7].Plasma glucose (PG),serum creatinine (Scr),total cholesterin (TC),triglyeride (TG),kidney mass (KM),index number of kidney hypertrophy (KM/body mass,KM/BM),and 24 hours urinary albumin (24 h UAL) were determined. The protein expression of monocyte chemoattractant protein-1 (MCP-1),osteopontin (OPN) and ED-1 in renal tissue were determined by immunohistochemical technique.The mRNA expressions of MCP-1 and OPN in kidney tissue were assessed by reverse transcription-polymerase chain reaction (RT-PCR).Results Elevated 24 h UAL was markedly attenuated by triptolide treatment [24 h UAL,triptolide:2.32?0.29 vs diabetic model group:3.89? 0.51 mg/mgCr,P

Proteomic technology has been widely used in the research of differently-expressed proteins under different physiology and pathologic conditions.In the aspect of the human spermatozoa proteomics,many reports have demonstrated the differently expressed proteins and the roles of sperm under different physiology and pathologic state from proteome level,and these results provided reliable theoretic base for well understanding of sperm molecule mechanism in physiology and pathologic conditions.

Objective To assess the abstracts on randomized controlled trials ( RCT) in non-small cell lung cancer ( NSCLC) published in Chinese and their influencing factors.Methods RCT in NSCLC published in Chinese were included according to the CONSORT statement and their influencing factors were analyzed by RevMan 5.3 soft-ware.Results The titles were identified as random, randomization, blinding, statistical method, recruited partici-pants, trial registry and fund-supported, respectively, in 20%of the 2677 abstracts included in this study.Con-clusion The titles are identified as random, randomization, blinding, statistical method, recruited participants, trial registry and fund-supported in RCT published in Chinese.Although the abstracts are improved after the publication of CONSORT, they need to be further brushed up.

The HIV susceptibility and resistance alleles in the HLA genes were determined by investigating the distribution characteristics of the HLA alleles (A,B,and DRB1) in HIV-infected individuals of the Han population in Hubei,and by comparing these alleles with HIV-negative individuals from the same area.A cohort of 424 HIV-1 infected individuals were chosen as study subjects,and 836 HIV-negative healthy subjects from the same area served as the control population.HLA-A,B,and DRB 1 allele typing was performed using polymemse chain reaction-sequence-specific oligonucleotide probes (PCR-SSOP) and polymerase chain reaction-sequencing based typing (PCR-SBT) techniques.Arlequin ver3.0 was used to analyze the allele and haplotype frequencies of HLA-A,B,and DRB l,whereas Epi Info 7 and SPSS18.0 was used to analyze the differences in the HLA alleles between the HIV-1 positive and HIV-1 negative groups.A*02:03,DRB1*01:01,and DRB1*15:01 alleles and their haplotypes as well as the HLA_Bw4-Bw6 hybrid showed a protective effect on HIV-1 infection.After adjusting for confounding factors such as age and sex,multivariate logistic regression analysis revealed that B* 15:02G,DRB 1*01:01,and DRB 1 * 15:01 subtypes were the resistance genes of HIV-1 infection,while B * 13:01 might increase susceptibility to HIV-1 infection.The correlation between A*02:06 and B*15:01G subtypes and HIV-1 susceptibility was independent of the age and sex of the host.This study demonstrated the influence of genetic factors in humans such as HLA polymorphism on individuals to resist HIV-1 infection.Association studies of HLA polymorphism,susceptibility/resistance to HIV-1 infection,and hosts' genetic background are of significant importance for research on HIV-1 pathogenesis and vaccine design.

Cell culture plays an important role in virology. It provides a platform for the detection and isolation of viruses as well as for the biochemistry and molecular biology based studies of viruses. In the present work, a new system that could permits multiple (different) cell lines to be simultaneously cultured in one dish was developed. In the system, each cell line was cultured in an isolated zone in the same dish or well and the system is therefore called an isolated co-culture system. The usefulness of this novel approach for virus isolation was demonstrated using a model system based on adenovirus.

Objective To investigate a modified technique of pancreaticojejunostomy in pancreaticoduodenectomy ( PD ).Methods The clinical data of 72 patients of PD using the modified technique of duct-to-mucosa pancreaticojejunostomy for treatment of benign or malignant tumor of pancreas or duodenum was retrospectively analyzed.Results There were no operative deaths; 2 of the 72 patients (2.78%) had postoperative pancreatic fistula. 63 patients were followed up. Of the 63 cases, the digestion and absorption functions of gastrointestine were normal in 60 patients and they were well nourished,but 3 patients suffered from chronic steatorrhea and malnutrition.Conclusions The modified duct-to-mucosa pancreaticojejunostomy is a simple and safe technique. With this technique, the rate of pancreatic fistula or leakage is relatively low and the function of the remnant pancreatic is well preserved.
