The method of acupuncture combined with rehabilitation training in the treatment of shoulder hand syndrome after stroke is reliablet, quick, with simple operation and less adverse reactions. Among them, characteristic acupuncture could focus on the targeted points with obvious effect than ordinary acupuncture, and the combination with rehabilitation training could greatly improve the curative effect. However, there still exist some problems in the current research, such as the difficulty of conducting blind clinical trials of acupuncture therapy; the lack of follow-up data in the evaluation of curative effect, the uncertainty of long-term curative effect; the small sample size of clinical research, etc., so multi-centered and large sample RCT research are still needed.

Objective To investigate human papilloma virus(HPV) infection in normal endometrium, atypi-cal hyperplasia of endometrium and endometrial carcinoma. Methods By the nucleic acid hybridization,we detected 28 pairs of endometrial carcinomas, 21 pairs of atypical hyperplasia of endometrium. Normal endometrium from 16 pa-tients with uterine myomas were as control. Results HPV16/18 DNA was detected in 25 endometrial carcinoma and 2 atypical hyperplasia of endometrium and 1 normal endometrium. Conclusions Endometrial carcinoma HPV16/18 DNA were significantly higher than those infected with atypical endometrial hyperplasia and normal endometrium. Note the occurrence of endometrial cancer,the development may be associated with HPV infection.

Objective To analyze the significant impact factors of postoperative hemorrhage after pancreaticoduodenectomy.Method The clinical data of 154 patients who underwent pancreatieoduodeneetomy from Jan.2009 to Jun.2012 were retrospectively analyzed.Results The incidence of postoperative hemorrhage was 10.4％ (16/154).The mortality caused by this complication was 12.5％ (2/16).Among these patients,intra-abdominal hemorrhage occurred in seven patients,and gastrointestinal hemorrhage occurred in nine patients.One patient suffered from both these complications.There were five and two patients presenting with early or delayed intra-abdominal hemorrhage,respectively.Early and delayed gastrointestinal hemorrhage occurred in three and six patients,respec tively.Statistical analysis showed that infection (P=0.002,P＜ 0.01) and pancreatic fistula (P=0.048,P＜0.05) are significantly associated with postoperative hemorrhage.Conclusions Postoperative hemorrhage after pancreaticoduodenectomy is a severe complication.Adequate hemostasis and prevention of pancreatic fistula and infection are the key points in reducing postoperative hemorrhage.Proper treatments should be used according to the site,type of onset and severity of hemorrhage.

Objective To investigate the effect of lean management on emergency biochemistry test turnaround time(TAT) in clinical laboratories.Methods Based on the approaches of standardized operations,5S on-site management,the efficiency evaluation of batch processing and one piece flow,and visual management,the median time of each workflow,the qualified rate of emergency biochemistry test TAT,the unqualified rate in a relatively concentrated period of TAT timeout and the unqualified rate of collected samples were compared before and after optimization.Results The median times (interquartile ranges) of each workflow including sample receipt and storage,result audit and sample storage-result report before and after lean management were 30 (35) min,7 (13) min,17 (8) min and 16(19) min,5(9) min,16(7) min,respectively,and there were significant differences in the former two(all P ＜0.01) but not the third (P ＞ 0.05).The median times (interquartile ranges) of TAT before and after lean management were 63 (51) min and 46 (33) min,respectively(P ＜ 0.05).The qualified rate of TAT increased from 86.00％ to 95.37％ after lean management(P ＜ 0.01).The unqualified rates in a relatively concentrated period of TAT timeout and collected samples decreased from 3.42％ to 1.00％ (P ＜0.01) and from 0.24％ to 0.17％ (P ＜ 0.01),respectively.Conclusion Lean management may improve process efficiency,reduce errors,and shorten emergency biochemistry test TAT in clinical laboratories.

Objective:To investigate the changes and significances of serum cystatin C and transforming growth factor-β1 levels for the neonatal asphyxia.Methods:Forty-six asphyxia newborns were chosen as the asphyxia group,and thirty healthy newborns were selected as the control group.The TGF-β1,CysC,BUN,Scr,and GFR levels of both groups were detected on the 1st,3rd,7th day after hospitalization.According to the renal injury,the 46 newborns were divided into normal group and asphyxia group,and the serum indexes were detected and analyzed.Results:On the 1st,3rd,7th day after hospitalization,the TGF-β1,GFR of asphyxia group was obviously increased and was lower than those of the control group (P＜0.05);the level of CysC,BUN,Scr in both groups were decreased,and the change degree in asphyxia group were higher than that of the control group (P＜0.05);the CysC,BUN,Scr in renal injured group were higher than those of normal group,and TGF-β1,GFR were much lower (P＜0.05).Additionally,TGF-β1 level of renal injured group was negatively correlated to the BUN and Scr,and positively correlated with the GFR (P＜0.05).The level of serum CysC in renal injured group was positively correlated to BUN and Scr and negatively correlated to GFR (P＜0.05).Conclusion:The serum TGF-β1,CysC in asphyxia newborns had significant changes compared with the healthy newborns and was correlated to the renal injured indexes,which had clinical directive significance on the early diagnosis,condition judgment,and prognosis of neonatal asphyxia with renal injury.

Objective To study the influencing elements in x-Gal staining method and optimize the reactive conditions so that nonspecific background can be eliminated and grafted exogenous cells carrying LacZ gene can be discerned correctly. Methods C17 2 cells (carrying lzcZ gene) were injected into the right lateral ventricle both in the adult and newborn animals. After one week they were perfused using two methods, then the slices were stained at different pH and incubating time respectively. The X-gal positive cells in hippocampus were counted under light microscope. Results Background staining in this method has close correlation with the species and age of the host animals and it decreases when pH is higher or incubating time is shorter. The results are the best when pH 9 5 and the incubating time is 1*!h.Conclusion The reliability of X-gal staining method depends on optimization of several parameters, including pH, incubating time, perfusion etc. It is necessary to establish the correspondent controls.;
