Objective To explore the methods in repairing the thenar wounds by microsurgical technique Methods Since 1989, thenar wounds were restored with transfer of superficial or deep palmar arch, recombine of thenar muscle flap Patch of nerve and transplantation of flap on 21 cases Results The thumb and flap were survived The two point discrimination was 5 to 10 mm The thenar muscle streugth reached MRC 4 with satisfactory oppones fuction Conclusion The thenal wounds cna be obtained good effect being repaired by microsurgical technique

Objective To evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with hypofractionated 3 dimensional conformal radiotherapy for hepatocellular carcinoma (HCC). Methods During May 1998 and Dec. 1999, 81 unresectable HCC patients were divided into two groups. Forty one patients in group A were treated with TACE and hypofractionated 3 dimensional conformal radiotherapy and 40 patients in group B were treated with TACE alone. Acute effects were analyzed and survival rates were assessed from the date of the beginning of treatment using the Kaplan Meier method. The survival rates of two groups were compared using Log rank. The Cox proportional hazards model was used to analyze the prognostic factors in group A. Results The objective response rate in group A was higher than that in group B (85.4% vs. 65.0% , P

Objective To investigate the molecular epidemiology as well as the subtypes of HIV in intravenous drug abusers, which can help pursue the source of infection in Zhejiang province and predict the epidemic strain in the future. Methods Such as ELISA, Western blot, nest PCR, DNA and sequencing technologies were used to analyze HIV subtypes of 15 strains isolated from intravenous drug abusers(IVDU) from Xinjiang autonomous region. Results All of the 15 IVDUs were infected with HIV 1, 2 of which were infected by subtype E and the others were infected by subtype C. Conclusions Subtype C is main HIV subtype infecting IVDUs. The epidemic subtype may have changed in China.

Objective To investigate the expressions of nitric oxide synthase (NOS) protein and mRNA in the lung of rats with hepatopulmonary syndrome. Methods Male Sprague-Dawley rats were divided into four groups: sham operation (SO), intrahepatic portal hypertension (IHPH), prehepatic portal hypertension (PHPH) and portasymstimic shunt (PCS). Two weeks after preparation of rat models, the following measurements were performed: arterial blood gas analysis; the concentrations of NO in lungs; in situ hybridization of ecNOS and iNOS mRNA expressions in lung tissue sections with digoxin-labeled ecNOS and iNOS oligonucleotide probes; expressions of ecNOS and iNOS proteins by immunohistochemisty; image and semiquantitative analysis of the expressions of ecNOS, iNOS and their mRNA. Results PaO_ 2 was (73.85?6.51) mmHg in IHPH rats, significantly lower than that in PHPH, PCS and SO rats97.39? 1.33, 95.23?2.22 and (99.05?0.75)mmHg, respectively.The level of lung NO of IHPH was(19.78?5.33)?mol per gram of protein,much higher than that of PHPH, PCS and SO 13.21?3.99,13.89?3.16 and (8.71?1.68)?mol per gram of protein,respectively. In capillary endothelia, positive expressions of ecNOS mRNA and ecNOS protein in IHPH(4.96?0.82,4.11?0.28) were significantly higher than those of PHPH (1.81? 0.39, 1.63?0.18), PCS (1.88?0.53,1.83?0.16)and SO(1.19?0.32,0.98?0.20). Conclusion The expressions of NOS protein and mRNA in the lung of rats with hepatopulmonary syndrome were increased, and the level of lung NO was elevated, which seems to play an important role in the pathogenesis of hepatopulmonary syndrome.

By the breeding model of physics mutagenests (60Co,UV light) and re-strong in the body of insects, We obtained a Bt strain Bt99985 with high insecticidal activity. The shake flask and 40t tank fermentation tests showed that, this strain showed special activity against Spodoptera exjgua, Comparing with original Bt strain: 93005, CK strain: HD-1-580 and GC-91, the value of potency increased respectively by 429%, 655% and 114% in shake flask test. Comparing with GC-91, the value of potency increased by 180% in 40t tank fermentation test.
