A fragment sized 400bp of White spot syndrome virus（WS SV，formerly de signated NOSV），recovered from recombinant plasmid pAFD, was labeled with Digox igenin as a probe to detect dynamic distribution of WSSV within 120h and 72h in crawfishes（Cambarus proclarkii） inoculated WSSV by oral taking and injecti on r espectively. Stomach epithelium, intestine epithelium, heart, gill, haemolymph, muscle, hepatopancreas, hypoderm, connective tissue and ovary of infected crawfi shes were examined for WSSV. In both groups, WSSV was first detected in heamoly mph at 12h p.i. and then disappeared. Again it was detected at 96h p.i. only in oral infection group and maintained till 120h p.i., but it didn't appear at 72h p.i. in injection group. WSSV in heart, muscle was detected at 36h p.i. in oral infection group and 24h p.i. in injection group respectively, and then increased generally. In addition, WSSV in intestine epithelium, connective tissue, ovary of oral infection group and intestine epithelium, hypoderm, ovary of injection g roup could also be detected. In dead crawfishes after 120h and 72h p.i. in two groups, WSSV could be detected in all the examined tissues and it demonstrated t hat systemic infection occurred in the animales. The tissue containing more amo unts of WSSV was hypoderm in oral infection group, while intestine epithelium, g ill, hypoderm, ovary in injection infection group. It deduced that WSSV first a ppears in haemolymph and then goes into heart, muscle and other tissues and prol iferates in them. Once again, WSSV is released into heamolymph resulting in syst emic infection till crawfishes' death.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.

METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.

RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).

CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.

ObjectiveTo discusse the relationship between static balance in laboratory approaches and dynamic balance in clinical assessment and identify the value of static and dynamic balance at functional outcome in hemiparetic stroke patients. MethodsNineteen stroke subjects were assessed in this study. The static balance was measured by postural sway test, the dynamic balance was measured by Berg balance scale(BBS)and Time up to go test(TUGT),the outcome was measured by FIM and 10m maximum walking speed(MWS). The level of association between the parameters of postural sway test and clinical variables were examined with Pearson's correlation coefficients. ResultsThe parameters of postural sway test was significantly negative related to BBS(r=-0.705--0.475,P<0.05);The parameters of postural sway close-eye test was significantly positive related to TUGT(r=0.508-0.583,P<0.05);The parameters of postural sway test was no related to FIM and MWS (r=-0.048--0.296;r=-0.404--0.01,P>0.05);BBS was significantly positive related to FIM and MWS(r=0.752;r=0.700,P<0.001). TUGT was significantly negative related to FIM and MWS(r=-0.600,P<0.01;r=-0.817,P<0.001).ConclusionClinical and laboratory balance assessments are related and that dynamic rather than static balance measures are valid indicators of functional outcome performance in hemiparetic stroke patients.

Objective To evaluate the outcome of the laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy. Then define the characteristics of the learning curve of this procedure. Methods A prospectively collected database comprising all medical records of the first 79 consecutive patients underwent laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy performed by one surgeon was studied. The patients were divided into seven groups (13 cases in last group) by operative sequence. Data on patients' demographics, clinical and outcome variables including operative duration, conversion to open surgery, complications, and length of hospital stay were analyzed. The learning curve for the laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy was established through the moving average and ANOVA methods. Results Comparing the early with the late experiences (33 v. 46 cases), the surgeon-specific outcomes significantly improved in terms of operating times [(292.7 ± 29.8) vs (215.3 ± 10.2) min, P < 0.05], There was four patients converted to open surgery in the early of experiences.the late experiences was five case, it was no statistical significance. significant differences were not shown in the hospitalization period and infectivity complications. Conclusion Operative duration can be reduced with increasing experience of laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy, In this study, the learning curve for a laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy was about thirty-three cases.

Objective To investigate the effect of Jiawei Naotaifang on neuronal apoptosis and the mechanism in ovariectomized rats with cerebral ischemia. Methods Female Sprague-Dawley rats(n=40)were randomly divided into sham group(n=10),model group(n=10),es-trogen group(n=10)and Jiawei Naotaifang group(n=10).The model group,estrogen group and Jiawei Naotai-fang group were ovariectomized.Eleven days after ovariectomy,the estrogen group and Jiawei Naotaifang group were given estrogen and Jiawei Naotaifang respectively intragastrically for three days.14 days after ovariecto-my,the model group,estrogen group and Jiawei Naotaifang group were modeled cerebral ischemia with Langa's method.24 hours after modeling,the apoptosis rate of neurons was detected with TUNEL,and the activation of extracellular signal-regulated kinase 1/2(ERK1/2)and c-Jun N-terminal kinase(p-JNK)in hippocampus were de-tected with Western blotting. Results Compared with the model group, the apoptosis rates decreased in Jiawei Naotaifang group and the estrogen group(P<0.001),with more activation of ERK1/2(P<0.01)and less activation of JNK(P<0.01). Conclusion Jiawei Naotaifang can protect neuron from apoptosis by promoting the activation of ERK1/2 and inhibiting the activation of p-JNK.

Objective To investigate the safety of preoperative hepatic and regional arterial infusion chemotherapy in the prevention of liver metastasis and improving survival after curative colorectal cancer resection.Methods Patients admitted from 2001 to 2007 with Stage Ⅱ or Stage Ⅲ colorectal cancer were randomly assigned to receive preoperative hepatic and regional arterial infusion chemotherapy (PHRAIC group,n=256)or surgery alone(control group,n=253).Toxity of liver,hematology,immunology and post-operative complication of PHRAIC and the control were evaluated.Results Grade Ⅲ hepatic toxity,leukemia,anemia and platelet decrease in PHRAIC group was 3.1%(8/256),5.5% (14/256),7.4%(19/256)and 6.6%(17/256).There were no grade Ⅳ toxities,and all the patients in PHRAIC group received surgery.Morbidity rate in PHRAIC and the control group was 9.8%(25/256)vs 8.3%(21/253)(X2=1.86,P＞0.05).All patients were followed up,with mean follow up of 42±14 months until Oct 30.2007.For stage Ⅲ patients,5-year overall survival and liver metastasis rate were 81.0% in PHRAIc group vs.60.4% in control group(X2=5.15,P＜0.05)and 18.9%(28/148)vs 27.3%(41/150)(X2=5.41,P＜0.05),respectively.Conclusion Preoperative hepatic and regional arterial infusion chemotherapy 7 days before surgery was safe and could reduce liver metastasis and improve survival rate in patients with Stage Ⅲ colorectal cancer.
