Objective: To study the influence of the Ewi-anticarcinogen Prescription on associated gene protein in process of rat hepatocarcinoma induced by diethylnitrosamine (DEN). Methods: Rats hepatocarcinoma model was induced by DEN, while the Eqi-anticarcinogen Prescription was used during the stage. At the end of 12th week and 16th week, the influence of the Eqi-anticarcinogen Prescription on positive expression of PCNA and p53 protein were examined by immuneohistochemical method. Results: The positive expression of p53 protein was occurred in precancerous hyperp lastic nodules; The Eqi-anticarcinogen Prescription can significantly inhibit the overexpression of p53 (P

Objective To understand the influence of personal feature on nurses' professional identity.Methods Nurses of 6 military hospitals were assessed and analyzed by general data questionnaire,Nursing Professional Identity Scale.Results Nurses' professional identity in military hospital was on the moderate level.Nursing age,department,monthly income,position,gender entered into the regression equation of nurses' occupation,which affected positively nursing professional identity.Conclusions The military nursing managers should raise the income of nurses appropriately,especially pay attention to training of professional identity of seniority nurses and local recruitment nurses,and enhance master concept in order to increase their understanding and recognition of their occupation.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.

Objective:To observe influence of qingzhifugan pellet on mixed-type animal model of fatty liver with chronic hyperlipemia and alcoholized hepatic damage. Methods:The mixed-type animal model of fatty liver was established by administering with high lipids and alcohol feeds. Therapeutic experiments were conducted with a self-made new drug the qingzhifugan pellet. The efficacy of the tested drug was evaluated comprehensively by such measures as sero-level of lipids and ferments,as well as the histological pathology of liver. Results:It was shown that the tested drug can decrease the sero-level of lipids,promote the metabolism of lipids in liver,recover the alcoholized hepatic damage,and relieve the liver fat denaturation. Conclusion:It suggested that the tested drug possessed certain effect for treating or improving chronic hyperlipemia and alcoholized hepatic damage in the animal model.

Objective:To evaluate the potential mutagenicity of Echinacea Herb P.E via salmonella typhimurium Ames test. Methods:To test the Echinacea Herb P.E diffusion through Ames test. In the plate incorporation test of Salmonella Typhimurium,the average number of spontaneous revertants of TA97,TA98,TAl00,and TA102 at four concentrations was calculated after incubation at 37 ℃ for 48 hours. Results:Whether added S 9 or not,the number of induced revertants when compared to that of spontaneous revertants did not increase statistically significant. The result of Ames test was negative. Conclusion:Echinacea Herb P.E will not cause the increase of the back mutation in murine typhoid salmonella which shows that Echinacea Herb P.E will not cause gene mutation.

Objective To study the effects of several enhancers on transdermal permeation of berberine hydrochloride. Methods The penetration rate of berberine hydrochloride through rat skin in 30% ethanol-water was measured using the penetration experiment apparatus. Samples were withdrawn from the receptor solution at certain time intervals and assayed by HPLC method. Results The penetration rate of berberine hydrochloride by the enhancers was increased in the following order: azone

Objective To explore effect of different withdrawal time of dexmedetomidine (DEX) on the quality of general anesthesia recovery.Methods Eighty patients of ASA Ⅰ or Ⅱ undergoing lymph surgery were randomly assigned to four groups (n =20).Groups D1,D2 and D3 received DEX 0.5 μg/kg as bolus before induction,continued with 0.5 μg/(kg · h) by infusion until one hour,30 min before the end of operation and the end of operation,respectively.Group C received equal volume of normal saline.Mean artery pressure (MAP),heart rate (HR) and pulse oxygen saturation (SpO2) were observed during and after operation.Spontaneous respiration recovery time,eyes open time,extubation time,orientation recovery time,observer's assessment of alertness/sedation score (OAA/S),restlessness score (RS),and visual analogue scales (VAS) were observed after operation.Results For MAP and HR in Groups D2 and D3,there were no statistically significant difference during extubation compared to those at preoperation,but at the same time point,they were lower than those in group C (P ＜ 0.05).For groups C and D1,MAP and HR at extubation and 5 min after extubation were higher than those at preoperation (P ＜0.05).Spontaneous respiration recovery time,eyes open time,extubation time,orientation recovery time in group D3 were significantly longer than those in Group C (P ＜ 0.05),while there were no statistically significantly difference between groups D1,D2,and group C.OAA/S in group D3 was significantly lower than that in group C (P ＜ 0.05) at extubation.Incidence of restlessness,VAS,and cases given analgesic 2 hours after operation in groups D2 and D3 were significantly lower than those in groups C and D1.Compared to those in group C,dosages of propofol and remifentanil in groups D2 and D3 were significantly lower.Conclusions Dexmedetomidine administered of 0.5 μg/kg before induction,continued with infusion of 0.5 μg/(kg · h) until 30 min before the end of operation,may improve emergence,without influencing the awakening time of patients,and prolong the duration time of analgesia which comfort the patients.

Arg-Gly-Asp (RGD) is a unique minimal integrin-binding sequence found within several glycoprotein ligands and also in snake-venom disintegrins. Adinbitor, a protein with 73 amino acid residues including 12 cysteins and an RGD motif, was cloned from Gloydius blomhoffi brevicaudus in my laboratory. As a new member of disintegrin family, adinbitor can inhibit both human platelet aggregation induced by ADP and angiogenensis in vivo and in vitro, the typical characters of disintegrin family. To separate the effect of inhibiting platelet aggregation from that of inhibiting angiogenensis, the motif KGD was introduced into adinbitor cDNA to replace RGD by site-directed and PCR-based mutagenesis. The recombinant protein (recombinant adinbitor (KGD)) was expressed in E. coli BL21 and purified through the His· Bind affinity chromatography. Recombinant adinbitor (KGD) could inhibit ADP-induced platelet aggregation with IC50 value of 85 nmol/L. Considerably, it was a more effective inhibitor on platelet aggregation than recombinant adinbitor (RGD), which has an IC50 of 150 nmol/L. Interestingly, recombinant adinbitor (KGD) has no potency in inhibiting angiogenesis in vivo compared with recombinant adinbitor (RGD). These findings showed that KGD containing adinbitor was more suitable for inhibiting ADP-induced human platelet aggregation as a potential and specific inhibitor of human platelet aggregation, which might have promising therapeutic potential as an antithrombotic agent.
