ObjectiveTo investigate the value of cavity isolation method on left colorectal obstruction in the anastomosis isolation. Methods60 patients with left colorectal obstruction were randomly divided into two groups:ileostomy group and cavity isolation method group,30 patients for each. After left colon resection was completed, ileostomy anastomosis group used the traditional method for colorectal anastomosis, and protected the anastomosis by ileostomy. Cavity isolation method group protected the anastomosis by cavity isolation method. Then the indexes in the two groups,such as anastomotic height, operation time, anal exhaust time,incidence of anastomotic leakage and its complications,hospitalization time, medical cost and so on were analyzed. Results Longer postoperative hospital stay (9.3 + 4.2) d were observed in ileostomy group than those ( 15.6 + 3.3 ) d ( P ＜ 0.05 ). Earlier time of the first flatusand oral intake(87.2 ± 6.3 ) h, ( 91.2 ± 7.2 ) h were observed in ileostomy group than those ( 101.8 + 7.5 ) h,( 117.3 ± 8.6) h in cavity isolation method group ( all P ＜ 0.05 ). ConclusionThe anastomosis isolation was a safe and feasible new technology that could reduce the complications caused by anastomotic leakage, and it had the advantages of short hospital stay, low cost,less suffering ect.

Objective To investigate the test-retest reliability of Muscle Evaluation and Treatment System on healthy adults. Methods 30 healthy adults participated in this study and were tested by Muscle Evaluation and Treatment System, designed by University of Shang-hai for Science and Thechnology and Rehabilitation Department of Huashan Hospital, on muscle strength of both sides' flexor carpi mus-cles, musculus flexor digitorum sublimis, flexor digitorum profundus, extensor digitorum muscle, extensor carpi muscles. Peak torque, peak torque per weight, largest single work, largest single work per weight, average torque, average power were the main parameters. Each partici-pant was tested 2 times, and the interval was 7 days. Results Almost perfect test-retest reliability of peak torque was performed on flexor car-pi muscles, musculus flexor digitorum sublimis, flexor digitorum profundus, and extensor carpi muscles. Moderate to excellent test-retest re-liability of average power were performed on extensor digitorum muscle. Conclusion Good test-retest reliability of Muscle Evaluation and Treatment System is proved in the study.

Purpose:To compare the survival rates of hyperf ractionated radiotherapy plus concurrent chemotherapy with hyperfractionated rad iotherapy alone in the treatment of stage Ⅲ/Ⅳ nasopharyngeal carcinoma (NPC) a nd analyze the prognostic factors. Methods:Between December 1992 and December 1995, 144 NPC patien ts were randomized into hyperfractionated radiotherapy plus concurrent chemother apy (R +C) and hyperfractionated radiotherapy alone (R alone).Radiotherapy were similar in the two groups: 1.2 Gy/f, twice a day. Chemotherapy was given to R + C patients before and during the course of radiotherapy. Results:The 5-year overall survival rates of the R + C and R alone groups were 63.3% and 50.7%,repectively . The factors influencing the resu lts were N stage,chemotherapy and the peripheral blood hemoglobin concentration . Conclusions:Hyperfractionated radiotherapy plus concurrent chem otherapy can improve the survival rate, especially for the patients with N2-N3 stage.The negative prognostic factors for Ⅲ/Ⅳ NPC are N2-N3 stage, radiothera py alone and the reduction of hemoglobin during treatment.

The technical solution-oriented patent analysis method was retrieved from patent texts according to the corresponding data mining rules by analyzing the structure and descriptive model characteristics of key techniques in drug patents with HBV drug patent data as the empirical study object .The coincidence of effective information mined using this method and recognized by the experts was good, indicating that this method can be used as an auxiliary tool in mining the key techniques in drug patents.

[Objective] To summarize the therapeutic and nursing care of vacuum sealing drainage to treat skin avulsion injury. [Methods]We used the method of vacuum sealing drainage combined with split thickness skin graft and pre-and post-operation nursing care to treatment of 21 patients suffering with skin avulsion injury, and compared therapeutic effect with routine therapy group. [Result]Skin graft survival rate in VSD group was higher than in routine therapy group. The dressing change, wound healing time, hospitalization time in VSD group were lower in routine therapy group. [Conclusion] The method of vacuum sealing drainage is good in treatment of intervention skin avulsion injury.

Objective To establish a RP-HPLC method for determination of the concentrations of dextromethorphan and its metabolites dextrorphan in human urine.Methods Phenacetine was used as internal standard,and the urine sample was hydrolyzed by enzyme,alkalified and extracted with hexane-butanol(91).The separation was carried out on DiamonsilTM C18 column(250 mm?4.6 mm,5 ?m) with mobile phase of acetonitrile-1% triethylamine buffer solution(pH adjusted to 2.2 with H3PO4).Gradient elution was done for 0-15 min(20%-35% A).The flow rate was 1.0 ml/min.The detection wavelength was set at 280 nm and the column temperature was 40℃.Results The linear ranges of dextromethorphan and dextrorphan were 0.05-2.0 ?g/ml(r=0.999 9,n=5) and 0.5-20.0 ?g/ml(r=0.999 9,n=5),respectively,and their lowest detecting concentrations were 0.04 ?g/ml and 0.4 ?g/ml,respectively.The intra-day and inter-day precision were both less than 10%.The low,middle and high extraction recoveries were between 94%-108%.Conclusion Our method is accurate and sensitive,and is suitable for the CYP2D6 phenotype analysis and pharmacokinetic studies of dextromethorphan and its metabolites in human.

Object To compare the contents of alkaloids of callus at different period with tissue culture of fresh bulbs of Fritillaria mellea S. Y. Tang et S. C. Yueh.Methods To study the best condition of induction frequency of callus about some phytohormones, temperature and light, and then to determine the contents of alkaloids of callus in F. mellea. Results The best condition of induction frequency of callus above was NAA 1 mg/L+ 6BA 3 mg/L; temperature at (22?1) ℃ and scattered light; the contents of alkaloids were kept highest in about 20th day ofter the callus appeared.Conclusion The contents of alkaloids of callus are kept higher level than fresh bulbs of F. mellea.

Objective To examine clinical significance and relativity of heart-type fatty acid binding protein (H-FABP) and high-sensitivity C-reactive protein (hs-CRP) in patients with chronic heart failure. Methods Ser-um concentrations of H-FABP and hs-CRP were measured in 60 patients with chronic heart failure and 30 control subjects. Left ventricular ejection fraction (LVEF) was examined by Doppler echocardio graphic in all subjects. Re-sults Serum concentrations of H-FABP and hs-CRP were higher in patients with chronic heart failure than in con-trol subjects[(6.11±1.49)μg/L vs (4.24±1.40)μg/L,and (12.77±3.65)mg/L vs(4.85±1.35) mg/L,t=5.746 and 7.543,P<0.01] but LVEF was lower in patients with chronic heart failure than in control subjects [(42.13±6.55) % vs (61.50±3.89) %,t=-14.902,P<0.01]. In CHF subgroups,H-FABP and hs-CRP lev-el increased with advancing NYHA class (F=26.288 and 351.784,P<0.01) but LVEF decreased (F=252.834,P<0.01). The serum H-FABP concentrations had a positive correlation with serum hs-CRP concentrations (r=0.801,P<0.01),and a negative correlation with LVEF (r=-0.718,P<0.01) ;serum hs-CRP concentrations had a negative correlation with LVEF(r=-0.881,P<0.01). Conclusion Serum H-FABP and hs-CRP levels are in-creased with the worsening of CHF. H-FABP and hs-CRP level are pnsitiviely related. The quantitative determination of serum concentrations of H-FABP and hs-CRP is valuable for risk stratification in patients with chronic heart fail-ure.
