Objective To study the effect of apironolactone on the left ventricular remodeling(LVRM) in patients with acute myocardial infarction (AMI). Methods 90 patients with AMI were randomly divided into spironolactone group( n = 45 ) and control group( n = 45 ). Spironolactone 40mg/d was administered in addition to the routine treatment for spironolactone group; the control group was received the routine treatment. All patients with AMI were examined left ventficular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD) and LVEF on 7 days and 90 days by ultrasonic cardiogram(UCG). Results Two groups patients with AMI in each UCG parameter had no significant difference on 7 days(P > 0.05); LVEDD, LVESD of spironolactone group on 90 days were significantly lower than that in control group(P < 0.05) and LVEF of spironolaetone groupwas significantly higher than that in control group(P < 0.05). Conclusion Those findings indicate that in patients with AMI, spironolactone may prevent LVRM.

Objective To investigate the bacteriostatic effect of starch-based alkyl poly glycoside(APG).Methods The nutrient broth dilution method was used to investigate the inhibiting effect of C8-10,C12 and pilot product C12 APG to the E.coli and Staphylococcus aureus.Results Determination of antibacterial fluid absorption was performed after 24 h-reaction.The MIC of C12,pilot product C12 and C8-10 were 0.03125,0.25 and 0.0156 g/ml for the E.coli;and were 0.062 5,0.25 and 0.062 5 g/ml for Staphylococcus aureus.Based on bacterial culture counts,at the APG concentration of MIC or higher than the MIC,the inhibitory rate of bacteria was more than 99%,the bacteriostatic effect was accorded with the absorbance.Conclusion Starch-based APG may have some antibacterial effects.

Objective To investigate whether or not the pulmonary artery participates in the blood supply of lung cancer and its change of morphology and blood flow in lung cancer. Methods Two different colors of silicone were injected separately into the bronchial and pulmonary arteries of 33 rat models with squamous cell carcinoma of lung. The origin of blood supply of lung cancer and the morphologic change of pulmonary artery were observed under a stereomicroscope. The DSA of bronchial and pulmonary artery were performed simultaneously in 28 patients with lung cancer. Results The pulmonary branch of rat and patients were reduced, thinned and occluded in the affected lung. The pulmonary artery did not form tumor vessel, and pulmonary blood flow and perfusion were reduced or absent in the affected area. Conclusion The pulmonary artery didn′t participate in the blood supply of lung cancer. It is unreasonable to perform transcatheter chemo embolization for lung cancer via pulmonary arteriay.

ObjectiveTo explore the effect of percutaneous locking compression plate(LCP) internal fixation for distal tibial comminuted fracture.Methods35 patients of distal tibial Comminuted fracture were treated with percutaneous locking compression plate(LCP) internal fixation.ResultsAll patients were followed up for average 1.8 years(ranging from 1 to 2.5 years).All of cases have healed well,and the average bone healing was 14.6 weeks (ranging from 8 to 28 weeks ).All of them have no infection and no loosening or breakage of internal fixation.According to Mazur criterion,excellent effect 17 cases,good effect 16 cases,fair effect 1 case poor effect 1 case,94.3％ was excellent or good.ConclusionThe LCP internal fixation for distal tibial comminuted fracture have the advantage of less invasive,good internal fixation and bone union fastly and little complications.

Objective To explore the clinical value of the interventional and comprehensive treatment of iliac-femoral venous thrombus(I-FVT).Methods 32 patients with I-FVT were underwent interventional therapy.First the filter was implanted into the inferior vena caval via opposite side of femoral vein,then the catheteres were implanted into the pathologic regions within the vena to process the emboluses,and balloon-directed extend when necessary.Results The procedure of treatment was successful in all patients.The iliac-femoral veins were patent,swollen and pain symptom of lower limb disappeared gradually after operation.The followed-up study the longest period for 30 months showed no severe complications and recurrence.Conclusion The interventional and comprehensive therapy is of ideal effect on treating I-FVT,occuring interventional and comprehensive treatment has ideally effect to cure the patients with I-FVT.

Objective To evaluate effects of human papilloma virus(HPV)16E7 on expressions of six tumor suppressor genes(including MT1G, NMES1, RRAD, SFRP1, SPARC and TFPI2)in a cell line SiHa, as well as on its proliferation and apoptosis. Methods SiHa cells were divided into two groups to be transfected with a small interfering RNA targeting HPV16E7(E7SiRNA, experimental group)and an empty vehicle(negative control group) respectively, with SiHa cells receiving no treatment serving as the blank control group. After 48 hours, qPCR was performed to measure the mRNA expressions of E7 and six tumor suppressor genes, CCK?8 assay to evaluate cellular proliferative activity, and flow cytometry to assess apoptosis of SiHa cells. Results At 48 hours after the transfection, the experimental group showed significantly decreased E7 mRNA expression(0.25 ± 0.036, P<0.05), but increased mRNA expressions of the six genes(MT1G 1.403 ± 0.190, NMES1 1.720 ± 0.060, RRAD 1.390 ± 0.160, SFRP1 1.493 ± 0.120, SPARC 2.157 ± 0.144, TFPI2 2.060 ± 0.122, all P < 0.05). The proliferative activity of SiHa cells was significantly decreased(0.554 ± 0.130 vs. 1.028 ± 0.236 and 1.220 ± 0.126, both P<0.05), but the apoptosis rate was significantly increased(9.222%vs. 0.246%and 0.123%, both P<0.05)in the experimental group compared with the negative control group and blank control group. No significant differences were observed between the negative control group and blank control group in proliferative activity or apoptosis rate of SiHa cells(both P>0.05). Conclusion E7 may participate in HPV16?induced cellular malignant transformation by suppressing the mRNA expressions of 6 tumor suppressor genes, including MT1G, NMES1, RRAD, SFRP1, SPAR and TFPI2.

Objective To get the basic data of nasal figure of the Han nationality individuals in Xi'an area and provide for junsprudence and the reconstruction of skull. Methods Nasal height, length, depth and breadth of 313cases in Xi'an area, which had different age and sex, were measured by magnetic resonance imaging (MRI). Results Image of MRI could clearly show the figure of nose and the position we selected were correct and accuracy. The specific data were: Nasal length (male:34. 47±4.29 ～52.20±3.47, female:33. 11±3.33～46. 94±3.83); Nasal height(male: 39.22±3.68～59.49±2.30, female: 33.89±3.95～51.75±3.68); Nasal depth(male: 11.89±1.76～16.68±2.48, female: 10.69±1. 81～16.46±2.04);Nasal breadth(male: 33. 09±3. 83～42. 49±2.72,female:32.00±1.94～38. 86±2.61). So the results were credible. Conclusion The nasal figure of individuals in Xi'an area is different as their different age and sex. It promotes that the influence factors of age and sex must be considered in the facial reconstruction and medico legally reconstructing skull.

Objective To evaluate the therapeutic efficacy of transcather arterial chemoembolization for hepatic carcinoma and its influence on hepatic function. Methods Patients with HCC were divided into three groups according to repeated TACE times. The therapeutic efficacy was assessed with survival rate, car-cionma size and biologic response (AFP). Hepatic function was evaluated according to some hepatic param-eters(ALT,AST,ALB,DB,TB,PT). Results All three groups responses rates were 4.3%, 23.1% and 31.6% ;srespectively,liver function in group 1 and group 2 returned to its pretreatment level(P <0.05) ,but in group 3, liver function did not return to its pretreatment level associated with more repeated TACE times. The 1-,2-and 3-year survival rates of group 1 were 27.0%, 10.8%, 5.4% ; respectively, while those of group 2 were 57.1%, 33.3%, 19.0% ; respectively, which were not significantly different from those of Team 3 ,which was 62.5%, 37.5%, 18.8%, respectively. Conclusions (1) three to four repeated times TACE was an effective palliative treatment that prolongs survival of patients with HCC,while 1 to 2 re-peated times had a limited benefit; (2) Irreversible hepatic impairment induced by TAEC could affect its therapeutic efficacy.

The effects of cyclosporine A (CsA) on glucose metabolism and betancell functions in vivo in rats were investigated. CsA (20mg/kg, 2/d) was given to Spraguer-Dawley rats for 14d. After a 1.5g/kg body weight glucose load by gavage the plasma glucose at 1 h and the area under curve (AUC) of plasma glucose were higher in the CsA-treated group than in the control (P
