strains of fast-growing rhizobia isolated from Chinas western (mainly from Qinghai province),and 4 representative strains were compared by performing numerical taxonomy. 132 phenotypic characteristics were analyzed. The results of numerical taxonomy constructed a dendrogram. It shows that all the strains examined clustered into five phena at a similarity level of 79%. 16S rDNA PCR-RFLP were applied to 57 rhizobial strains (among the 61 strains) and 10 reference strains. The 16S rDNA-RFLP analysis described 20 different genotypic characteristics and form one dendrogram. For some large groups, the results of 16S rDNA-RFLP were agreement with that of numerical analysis of phenotypic characteristics.

Objective To observe the therapeutic efficacy and safety of recombinant tissue plasminogen activator (rt-PA) for treatment of patients with acute cerebral infarction and investigate the prognostic factors of thrombolysis. Methods The clinical data of 60 patients with acute cerebral infarction from January 2009 to November 2013 in Department of Emergency, Hangzhou Traditional Chinese Medicine Hospital were retrospectively analyzed;of them, 30 cases received intravenous rt-PA thrombolytic treatment, being in the thrombolytic group, 0.9 mg/kg rt-PA was given to the patient within 4.5 hours after the disease onset, the total dosage could not exceed 90 mg, in which 10%was intravenously injected and the rest 90%was intravenously dripped slowly within 60 minutes. That another 30 cases did not undergo thrombolytic therapy was assigned as the control group, and they took aspirin, etc anti-platelet aggregation routine treatment. Before and after thrombolytic treatment for 1 hour, 24 hours and 14 days, the National Institutes of Health Stroke Scale (NIHSS) score was evaluated in the two groups;before and after thrombolytic therapy for 0.5, 1.0, and 1.5 hours, the patient's scores of Barthel index (BI) were observed in the two groups. In thrombolytic group, the situations of hemorrhage transformation, symptomatic hemorrhage and modified Rankin scale (mRS) score in 3 months of the patients with different ages, complications and NIHSS scores were observed. Results Before treatment, no statistically significant differences were found in the NIHSS score (15.2±3.6 vs. 15.5±3.3) and BI score (45.0±8.8 vs. 44.1±7.6) between the control group and thrombolytic group (both P>0.05);after treatment with the extension of time, the NIHSS score was gradually reduced, reaching the lowest level on the 14th day after thrombolytic treatment, while the BI score was gradually increased, reaching its peak at 1.5 hours after thrombolytic treatment, the changes being more prominent in thrombolytic group (NIHSS score:9.7±2.6 vs. 12.8±4.2, BI score:82.6±7.8 vs. 69.6±9.8, both P<0.05). In thrombolytic group, there were cerebral hemorrhage transformation 2 cases, gum bleeding 3 cases, skin bleeding 1 case, urethral bleeding 1 case, gastrointestinal bleeding and black stool 1 case. In control group, cerebral hemorrhage transformation was seen in 1 case. There was no obvious systemic hemorrhage in the two groups. In the 30 cases in thrombolytic group, the baseline NIHSS score of patients>80 years old was higher than that in cases≤80 years old (15 vs. 12); the age (years: 71.0±4.1 vs. 61.5±2.6), baseline NIHSS score (14 vs. 11) and bleeding conversion rate [37.50% (3/8) vs. 18.18% (4/22)] of cases with atrial fibrillation were higher than those not complicated with atrial fibrillation; the NIHSS score of cases with elevated international normalized ratio (INR) was lower than those without elevated INR (11 vs. 14);The bleeding conversion rate [16.67%(1/6) vs. 29.17%(7/24)] with NIHSS score≤4 were lower than those with NIHSS score>4;the mRS score in 3 months (4 vs. 2), and percentage of 3-month mRS score≤2 [11.1%(1/9) vs. 52.38%(11/21)] in cases with NIHSS score≥20 was higher than that in cases with NIHSS score<20 (all P<0.05). The fatality rate of two groups was 3.33%. Conclusions The intravenous rt-PA thrombolytic treatment can significantly promote the early recovery of neurologic impairment for patients with acute cerebral infarction. The therapy can improve the prognosis and its safety is relatively good. Meanwhile it is similarly effective for cases over 80, with complications such as atrial fibrillation, raised INR, and with different degrees of severity.

Objective To evaluate the inhibitory effects of sustained-release 5-fluorouracil(5-FU)micmparticles on the growth of HepG2 eels.Methods The inhibitory effects of sustained-releage 5-FU micropartides,5-FU microparticles and poly L-lactic acid on HepG2 cells were detected by MTT assay.The HepG2 cell apoptosis was demonstrated by flow cytomerry after Hoehest staining.Results The survival rate of HepG2 cells in sustained-release 5-FU microparticles group decreased as time passed by.The survival rate of HepG2 cells in 5-FU microparticles group wag the lowest on the first day,and then it increased gradually.The survival rates of HepG2 ceHs in 5-FU microparticles group on day 21 and 28 were hJigher than those in sustained-release 5-FU microparticles group.The survival rate of HepG2 cells in poly L-lactic acid group WSB higher than that in the other two groups.The difference upon survival rate among the 3 groups had statistical significance(F=3163.52,128.47.P＜0.01).Conclusions The sustained-release 5-FU micropartieles could keep on inhibiting tlle growth and inducing apoptosis of HepG2 cells in time-dependant manner.The inhibitory effect of sustained-release 5-FU is better than that of 5-FU microparticles.

Objective To investigate the risk factors of extrahepatie recurrences after curative resection of primary hepatocellular carcinoma (HCC). Methods Clinicopathologic data of 238 curative resected cases of primary HCC were retrospectively reviewed for parameters affecting postoperative extrahepatic recurrences. Results During a median follow-up of 34 months (7 - 78 months), extrahepatic recurrences were observed in 32 out of 238 patients (13.4%). According to univariate analysis, the risk factors for extrahepatic recurrences were preoperative serum a-fetoprotein (AFP) level of > 1000 ng/ml,aspartate aminotransferase level of > 50 IU/L, presence of hepatic vein invasion, neighboring organ invasion, tumor satellites, and lack of tumor capsule formation. Preoperative serum AFP levels of > 1000 ng/ml, hepatic vein invasion, neighboring organ invasion proved to be independent risk factors by multivariate analysis. Conclusions Extrahepatic recurrences after curative resection of HCC was found to be related to preoperative serum AFP level of > 1000 ng/ml, hepatic vein invasion, and neighboring organ invasion.

Objective To explore the clinical value of total hemihepatic vascular exclusion (THHVE) in right hepatectomy for hepatocellular carcinoma (HCC). Methods One hundred and twenty-three consecutive patients who underwent right hepatectomy for HCC between February 2006 and December 2008 were studied retrospectively. THHVE was used in 58 patients (group A) and Pringle maneuver in 65 patients (group B). The patient's demographics,surgical procedure and outcome were collected and compared between the two groups.ResultsThe tumor size was significantly bigger in group A than group B (7.69±3.70 cm vs.6.08±4.07 cm,P＜0.05).The vascular occlusion time in group A was significantly longer than groupB (28.55±8.67 min vs.19.85±6.71 min,P＜0.05). However, intraoperative blood loss in group A was significantly less than group B (304.31±270.36 ml vs.542.62±876.84 ml,P＜0.05),and the elevation of serum alanine aminotransferase (ALT) on day- 1,-3 and- 7 after operation in group A were significantly lower than group B (P＜0.05).The postoperative complication rate in group A was lower than group B (18.97％ vs.38.46％,P＜0.05).ConclusionTHHVE was a safe and efficacious technique in right hepatectomy for HCC.It significantly decreased blood loss,alleviated liver injury and reduced postoperative morbidity and mortality.

OBJECTIVETo analyze and summarize the characteristics and treatment of acute spinal cord decompression sickness. To explore the factors that influence the treatment effect.

METHODS77 cases of acute spinal cord decompression sickness patients should be divided into 4 groups according to the pressurized treatment and drug treatment options. They were group I, group II, group III and group IV. At the same time they were get hyperbaric oxygen therapy and other treatment. The evaluation index, were Frankel function classification and paraplegia index. There were 17 factors that affected the treatment effect.

RESULTSThe rate of early cure was 57.14% (44/77). The rate of late cure was 74.03% (57/77). Their difference was statistically significant (P<0.05). In 3 months and 1 year the cure rate of group IV and group B were the highest. But there was no difference between them(P>0.05). They were higher than group ii and group I (P<0.05). The Frankel function classification in 3months and 1 year in each group was higher than before treatment (P<0.05). The paraplegia index in 3 months and 1 year in each group was lower than before treatment (P<0.05). In 3 months and 1 year the Frankel function classification was increased gradually and the paraplegia index was decreased gradually in group I , group II, group III (P<0.05). In group IV and group III the Frankel function and the paraplegia index had not significant difference (P>0.05). Among the 17 factors that affect the treatment effect there are 9 factors that affect the proportion of the large.

CONCLUSIONSThe first choice of treatment method for the patients with acute spinal cord decompression sickness would be group III. Drug therapy was also imporpant. At the same time the hyperbaric oxygen therapy and other treatments were taken. Although the cure rate was not high in this article. But most of the cure is within 3 months. Within 1 year.the cure rate still could be improved. 9 factors that affect the efficacy of acute spinal cord decompression sickness was more noteworthy.
