This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

Methods A prospevtive randomixed controllde study was conducted in 30 patients with digestive tract lip shape fistula admitted from January 2001 to November 2007,which were divided into experimental group ( 15 patienets) and control griup ( 15 patjients). The control group received traditional fistula mouth continuous drainage,with fastomg or part enteral nutrition and parenteral nutrition. The experimernal group received external obturatiion with cotton ball,with controling spills of oineteatinal fluid and resuming normal eating and activetes, The patients general information, fistuala mouth sixe, volume, weight, albumin, determinstic operation time, postoperative complications, hospital, signficantly reduced fistula, flow, postoperative compared between the two groups. Results Compared with the control group , significantly redced fistula, flow, postoperative complivations and cost, increased wdighe and albumin,as well as shortened operation time and hospital stay were found oin the experimetal grou. Conclusin External obturation with cotton ball is safe effective methde in treatment of digestive tract lip shape fistula, obviusly shortening the course of disease, redcing patients'cost and pain, and rapidly improving patients nutritional status.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

OBJECTIVETo make comparative study on HPLC-FPS of several kinds of Pueraria lobata and P. thomsonii from different sources.

METHODKromasil C18 column was used, with mixture of acetonitrile and water as mobile phase in a gradient mode. The wavelength of measurement was 250 nm.

RESULT AND CONCLUSIONThe fingerprints of P. lobata and P. thomsonii were obtained. This method can be used to identify P. lobata and P. thomsonii from different sources conveniently, and it may be practically valuable for the quality control of sample for P. lobata or P. thomsonii and its preparation.

The emergence of immune checkpoint inhibitors (ICIs) have changed the pattern of anti-tumor therapy and brought new hope to the treatment of small cell lung cancer (SCLC). Currently, ICIs are most widely studied mainly include programmed death-1/ligand-1 and cytotoxic T-lymphocyte antigen-4. Altezumab is recommended for the first-line treatment of extensive SCLC, while pebrizizumab is recommended for the third-line treatment of extensive SCLC. There has been no breakthrough in the second-line and maintenance treatment of SCLC with ICIs.

Objective To understand the knowledge and attitude of clinical pipeline nursing in nurses and provide evidence for carrying on aimed pipeline nursing training. Methods By convenience sampling, 91 surgery nurses were investigated with questionnaire. Results The average score of nurses in clinical pipeline nursing were (32.47 ±4.66), one-way ANOVA results showed that age, seniority, job title and the years they have been working for in the department were related to the nurses' knowledge and attitude about pipeline nursing. Conclusions Nursing managers should strengthen young nursing staff' s training and retraining of the knowledge about clinical pipeline nursing, especially the new knowledge of pipeline nursing, new developments,and should get the main points and carry on systematically.

Objective To explore intervention effect of palliative treatment of pancreatic cancer patients and their families to implement the same period nursing. Methods 48 cases of patients with pancreatic cancer were divided into intervention group and control group by odd and even numbers in hospital, each group was 24 cases, the intervention group implemented the same period nursing to the patients with pancreatic cancer and their families, the control group took the whole patient-centered nursing intervention, Before and after the intervention, the questionnaire survey was conducted to the patients by Hamilton Depression Rating Scale and the Perceived Social Support Scale, Patients were evaluated for depression and social support. Results After the nursing intervention to palliative treatment of patients with pancreatic cancer and their families to implement the same period nursing, patients with depression had significantly improved than that of the control group, the difference was significant [(10. 17 ± 2.41) vs (14.46 ± 1. 25), t = -7. 750, P ＜ 0. 01]; Intervention group in improving the perception of social support group was better than that in the control group [61.79±7.40) vs (51.08 ±4.94) ,t =5. 894,P ＜0. 0l]. Also it found, the control group scores after the intervention to support the family has declined compared with that before intervention, the intervention group scores after the intervention to support the family has increased compared with that before intervention, and differences were statistically significant (P ＜0. 01). Conclusions The methods of palliative treatment of patients with pancreatic cancer and their families to implement the same period nursing were feasible, help alleviate depression in patients and improve their quality of lives.

OBJECTIVETo investigate association between the natural-resistance-associated macrophage protein 1 (NRAMP1) gene polymorphisms and susceptibility to pulmonary tuberculosis (TB) in Chinese Han population.

METHODSHospital-based case-control study design was adopted. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) technique were used to type three NRAMP1 polymorphisms (INT4, D543N and 3'UTR). Information on related factors of tuberculosis was collected using a pre-tested standard questionnaire. Univariate and multivariate unconditional logistic analyses were conducted using SPSS for window software package. Totally, 110 cases of TB were selected during April 2001 to June 2002, with an average age of (27.7 +/- 12.7) years. Also, 180 cases of healthy control were selected, aged (27.3 +/- 9.2) years in average. Locus of NRAMP1 polymorphism was analysed with univariate method.

RESULTSUnivariate analysis demonstrated that the D543N G/A and 3'UTR TGTG+/del genotype occurred more frequently in the cases than in the controls, with crude odds ratios (OR) (95% CI) of 2.22 (1.03 - 4.78) and 1.93 (1.14 - 3.26), respectively. No significant association was observed between TB and INT4 polymorphisms. In multivariate analysis, associations of TB and D543N G/A and 3'UTR TGTG+/del genotypes remained, adjusted for exposure history and bacille Camette-Guérin immunization. Adjusted OR (95% CI) was 3.04 (1.12 - 8.27) and 2.36 (1.20 - 4.64), respectively. Still, no significant association between INT4 polymorphisms and TB was found.

CONCLUSIONPolymorphisms of D543N and 3'UTR locus in NRAMP1 gene might affect their susceptibility to TB in Chinese Han population.
