Objective: To observe the effect of Weixikang apozema on growth factor of acetic acid gastric ulcer rats.Methods: The rats were divided into blank control group(abbreviated as blank group),model group,ranitidine group,Weixikang low dosage group(abbreviated as low dosage group) and Weixikang high dosage group(abbreviated as high dosage group) at random,each group has 8 rats.The content of epidermal growth factor(EGF) and transforming growth factor-?(TGF-?) were measured with radioimmunoassay.The protein expression of EGF,TGF? and EGFR were measured with immunohistochemical method.Results: The content of EGF and TGF-? and the protein expression of EGF,TGF-? and EGFR in low dosage group and high dosage group have increased(P

Objective To evaluate the outcomes of thoracoscopy-assisted mini-incision procedure in patients with lung cancer.Methods From January 2003 to June 2003,66 patients with non-small cell lung cancer were treated in our hospital by lobectomy combined with mediastinal lymph node resection using thoracoscopy-assisted mini-incision(36 patients,VATS Group)or traditional surgery(30 patients,traditional group).The clinical and follow-up data of the two groups were compared after the operation.Results No significant difference was found in the operation time between the VATS and traditional groups(114.6?47.4)min vs(123.3?43.9)min,t=-0.768,P=0.449],while the postoperative hospital stay of the VATS group was significantly shorter than that in the traditional group (9.2?1.4)d vs(10.5?1.7)d,t=-3.408,P=0.001].Log-rank test showed that the survival curve in the two groups was comparable(?2=0.270,P=0.605).Cox regression model indicated that the pathological characteristics(risk ratio:3.912,P=0.000),TNM stage(risk ratio:3.737,P=0.000),and lymph node metastasis(risk ratio:15.495,P=0.000)were independent,unfavorable prognostic factors for the disease;whereas,no relation was detected between the thoracotomy incision and prognosis(P=0.414).Conclusions Thoracoscopy-assisted mini-incision procedure is a safe and reliable approach for patients with lung cancer with satisfying outcomes.

Objective To introduce the aim,design principles,function and characteristic of LIS. Methods Through functionalized design of module,this net management system is created by composed application,sampling,check,count,verify,auditing,issuance,quality control,query,consume control as an entirety. Results The accurate test data,the timeliness report and the query convenience were increased. Conclusion The LIS can provide exact and quick medical service for patients.

Objective To evaluate the efficacy of video-assisted thoracoscopic surgery for loop ligation in patients with spontaneous pneumothorax.Methods From April 2004 to December 2006,90 consecutive cases of spontaneous pneumothorax were subjected to video-assisted thoracoscopic surgeries for loop ligation in our department.The pulmonary bullae of the patients(

[Objective]Postoperative analgesia with the use of parenteral opoids or epidural analgesia can be associated with troublesome side effects.Good perioperative analgesia facilitates rehabilitation,improves patient satisfaction,and may reduce the hospital stay.We investigated the analgesic effect of locally injected drugs around a total knee prosthesis.[Method]Thirty-eight patients undergoing total knee arthroplasty were randomized either to reveive a periarticuiar intraoperative injection containing bupicaine,morphine,epinephrine,hydrocordisone or to reveive no injection.We compared the PCA consumption at the some time point after tatal knee arthroplasty.Visual analog scores for pain,preoperation and postoperation,6 weeks after operation were collected.[Result]The patients who had received the injection used significantly less patient-controlled analgesia over the first 24 hours after the surgery.They had lower visual analog scores for pain 24 hours and 48 hours after operation.No cardiac or central nervous system toxicity was observed.[Conclusion]The perioperative analgesia protocol improved patient satisfaction,pain control and minimizes side effects after total kneearthroplasty.

Objective To realize the inter-network connectivity problem through one information-point. Methods According to the characteristics of twisted -pair connections, following the work principles and standards of Ethernet, the transformation of twisted-pair was rebuilt by tri-pass connecting twin-network. Results Each pair of thread groups was taken full advantage by achieving twin-network. Conclusion By comparing the two types of transformation methods, a set of practical solution is explored of handy, mobility, non-destructive and reversible.

Scleroglucan produced by Sclerotium spp. is a non-ionic polysacchari de biopolymer which has excellent viscosifying power in a wide variety of reservoi r brines snows high shear resistance and possesses good thermal stability. This article reviews the production of Scleroglucan , the influence of the conditions to the fermentation, and the application in the oil field.

The main pollution of coastal sea is heavy metal and eutrophication,which resulted in degeneration of its eco-function.Pollution of heavy metal is accompanied with eutrophication in sea water.This article studied on copper absorption capacity of several bacteria strains which were isolated from the surface of macroalga Gracilaria lemaneaformis that was cultivated in copper polluted sea.We got 6 strains of epiphytic bacteria from the seaweed,Ochrobactrum anthropi,Aeromonas salmonicida,Micrococcus lylae,Corynebacterium ulcerans,Pseudoalteromonas spp,Vibrio fluvialis.Attained from the experiment of copper biosorption,A.salmonicida had a maximal biosorption capacity among them,and Vibrio minimal.Based on this trail,A.salmonicida,C.ulcerans and Vibrio were selected for next trails included optimal biosorption time,optimal pH value and effect of pre-disposal by several chemical reagents on biosorption capacity.The results showed:optimal biosorption time was between 40 minutes and 60 minutes,and optical pH value 4～5.Pre-disposal by HCl leaded to lost the absorption capacity of A.salmonicida,but was opposite by NaOH and ethanol.For C.ulcerans and Vibrio,the copper absorption capacities were increased by them.
