Objective: To study the effect of Baihuzhuifeng Pills (BHZFP) on interleukin 1?(IL 1?) secreted by synoviocytes in adjuvant arthritis (AA) rats. Methods: Synovium of knee joints from AA rats were digested by collagenase and tripsin to prepare DSSC(digested synovial single cells). The content of the supernatant fluid was assayed by the radioimmunoassay. Results: BHZFP down regulated IL 1? productions of DSSC.Conclusion: It is suggested that BHZFP be probably inhibit the over proliferation of synoviocyte in AA rats by diminishing IL 1? secretion.

Objective To summarize the surgical skills of the pancreaticoduodenectomy via mesenteric approach for the treatment of duodenal gastrointestinal stromal tumors (GISTs).Methods The clinical data of 1 patient with huge duodenal GIST combined with gastrointestinal hemorrhage and liver metastasis who was admitted to the Second Affiliated Hospital of Harbin Medical University in June 2014 were retrospectively analyzed.The patient had continuous bleeding before the operation.The results of computed tomography (CT) showed that there was a solid tumor below the liver and in front of the right kidney,with the size of 12.2 cm × 8.1 cm,inferior vena cava was squeezed by the tumor,a solid tumor was detected in the right lobe of liver,and the colon was suspiciously invaded by the tumor.The patient received pancreaticoduodenectomy,right hemicolectomy and right lobectomy of liver metastases.The patient was followed up by out patient examination and telephone interview up to August 2014.Results The operation time,volume of blood loss and volume of red blood cell (RBC) transfusion were 420 minutes,800 mL and 2 U,respectively,with a full recovery of patients.The duodenal GIST with metastasis tumor and necrosis located at the colon,pancreatis,liver and renal hilum was confirmed by pathological diagnosis.The life quality of the patient was good by follow-up at postoperative month 3.Conclusion In the pancreaticoduodenectomy via mesenteric approach,surgeons perform vigorously the method of mesenteric approach at the first stage of operation,it could maximally reduce the risk of operation and the volume of blood loss.

Objective To optimize the soaking treatment method for increasing the germination of Amomum villosum Lour.(AVL) seeds.Methods Nine groups were set up: the control group(without soaking treatment),treatment group 1(soaking AVL seeds with naphthylacetic acid 15 mg/mL for 8 hours),treatment group 2(soaking with gibberellin 100 mg/L for 30 hours) and treatment groups 3~8(soaking with clean water for 8,20,30,40,45 and 50 hours respectively).The sowing amount was 100 grains in each group for each time,and the seeds were planted in the outdoor pot at a planting space of 4cm?4cm.Results Naphthylacetic acid had an obvious inhibition on the germination of AVL seeds and delayed the shooting.Gibberellin promoted the germination and shooting of the seeds.Soaking with clean water for 8 hours had no obvious effect on the seed germination,but soaking for 20~50 hours increased the seed germination to various degrees,in particular soaking for 30~50 hours.Conclusion Soaking with gibberellin or clean water can increase the germination of AVL seeds.This method is simple and practical and economic,and is worth of extensively applying in the sowing and breeding of AVL seeds.

~3H-Clonidine, a potent and selective alpha2-adrenergic agonist was used to label alpha2-a-drenoceptors in intact lymphocytes isolated from rat spleen. Binding of ~3H-Clo-nidine was rapid(t1/2: 2min)and readily reversed by 10umol?L~(-1) clonidine(t1/2: 3-4min). ~3H-Clonidine saturationexperiments indicated a single c1ass of site with a K_D of 6.57?1.63nM and Bmax of 72.4?13.4 fmol/10~7 lymphocytes. Adrenergic agonists competed for ~3H-clonidine binding site with anorder of potency:epinephrine)norepinephrine)isoproterenol. These results show the presence ofalpha2-adrenoceptors in splenic lymphocytes. Computer analysis of competition experiments withadrenergic agonists revealed three classes of sites: high affinity site, medium affinity site and lowaffinity site. The affinity of high affinity site is 2-3 orders of magnitude higher than the one ofmedium affinity site, whereas the latter is the same orders higher than low affinity site Using im-proved Mishell-Dutton method, 10umol?L~(-1) clonidine suppressed the Ig M synthesis and thesuppression was blocked by 10 umol?L~(-1) phentolamine. These results indicate the suppression ofIg M antibody response to SRBC in vitro by clonidine is mediated by the alpha-adrenoceptors.

Objective To evaluate prognostic significance of early lactate clearance rate for cardiogenic shock patients on extracorporeal membrane oxygenation(ECMO).Methods Forty-seven patients with cardiogenic shock supported by venoarterial ECMO were prospectively enrolled from May 2010 to May 2013.Arterial blood lactate at pre-ECMO support(0 h),at post-ECMO 6 hours(6 h) were measured and then 6 h lactate clearance rate was calculated.90 days after admission was the endpoint of research.Patients were divided into the survival group(n =25) and the death group(n =22).6 h lactate clearance rate was compared between groups.The 6 h lactate clearance rate for predicting death was evaluated by receiver operating characteristic(ROC) curves.The surviving curve was drawn using the Kaplan-Meier method,and the survival of the patients was analyzed by the Log-rank test.Factors influencing the prognosis were analyzed by applying the multiplelogistic regression analysis.Results The 6 h lactate clearance rate was higher in survivors than in nonsurvivors [(38.6 ± 15.1) % vs.(14.4 ± 13.8) %,P < 0.05].The area under the ROC curve of 6 h lactate clearance rate for predicting death was 0.869 ± 0.075 (95% CI:0.753-0.991).The best cutoff point was 20.0% with a sensitivity of 92.0% and specificity of 85.0%.KaplanMeier survival analysis showed that 90 days survival rate of high lactate clearance rate group and low lactate clearance rate group were 66.7% and 35.0%,with significant difference between the two groups(Log-rank test,P < 0.05).Multivariate logistic regression analysis showed that 6 h lactate clearance rate (OR =3.156,95 % CI:2.326-7.253,P < 0.05) was one of the independent risk factors associated with mortality of patients on ECMO.Conclusion Early lactate clearance rate could be used as an important maker for evaluating the prognosis of cardiogenic shock patients on ECMO.

Objective To analyze Klebsiella pneumoniae by DiversiLab system, providing scientific evidence for the control of nosocomial infection. Methods Eight strains of non-duplicated clinical Klebsiella pneumoniae isolated from the surgical ward in a hospital in 2010 were typed by rep-PCR-based DiversiLab system. The results were compared with those of pulsed-field gel electrophoresis (PFGE). Results Antimicrobial susceptibility test showed that 7 clinical strains were the same sensitivity to 11 antimicrobial agents, except the strain K8-02. And these 7 clinical strains were all multi-drug re-sistant. The result of PFGE showed that 7 strains were the same pattern. The result of DiversiLab also showed that 7 strains were the same pattern, and the strain K8-02 was another pattern. Conclusion DiversiLab system is simple, quick, good re-peatability and accurate, which is a kind of standardization and automation system. DiversiLab system and PFGE method could get the same result.
