0.05).Conclusion Levofloxacin treating community-acquired pneumonia than gatifloxacin have more medicine economics advantage and it is in the prior choice.

0.05).Conclusion Gatifloxation is safe and efficient in the treatment of community acquired pneomonia.

Objective To explore the relationships between erythropoietin( EPO), endothelin - 1 (ET - 1) and perinatal anoxia. Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

Objective To assess the value of serum N terminal pro-brain natriuretic peptide(NT-Pro-BNP) in the diagnosis of congestive heart failure(CHF) and evaluation of cardiac function in children with ventricular septal defect (VSD).Methods Fifty one children were enrolled from March 2004 to March 2005.NT-Pro-BNP was measured by enzyme immunoassay technique.At the same time,left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were detected with echocardiography.Results The data of NT-Pro-BNP were showed but the logarithms of which were normal distribution.The values of NT-Pro-BNP were developed successively along with the severity of cardiac function.But there was no difference between the group of no heart failure and mild heart failure.But the values of LVEF and LVFS had no differences in the control,the mild and the moderate heart failure and the same time all of which beyond the standard of diagnosing heart failure.NT-Pro-BNP could reflect the degree of heart failure or cardiac function (r=0.826).But LVEF and LVFS can not reflect the degree of the cardiac function.Conclusions NT-Pro-BNP can reflect the degree of the cardiac function in VSD,and the degree of the heart failure can be classed by the levels of serum NT-Pro-BNP.But the value of LVEF and LVFS can not reflect the degree of the heart failure in the same disease.

Objective:To clone the RC-RNase gene and prepare its recombinant prokaryotic construct, and then to express RC-RNase protein using Escherichia coli system. Methods: RC-RNase cDNA was obtained by RT-PCR from liver of Rana catesbeiana, and cloned into pUCm-T plasmid for nucleotide sequencing. Its expression construct was prepared using the 6?His vector pRSET-A, and induced to express by IPTG in Escherichia coli BL21(DE3). Western blotting identified the expression product. Results: A 380 bp long cDNA was obtained from liver of Rana catesbeiana, restriction sites and sequence being consistent to those reported for RC-RNase. After introducing the gene into Escherichia coli and through the induction by IPTG, it was observed a new peptide at the expected position (Mr 16000) on SDS-PAGE gel. This product was proved to be the target protein via Western blotting. It existed in a form of inclusion body and its efficiency reached 12.5% of total bacterial proteins. Conclusion: RC-RNase gene was cloned and expressed in Escherichia coli. The protein could be used for characterizing the biological activities and function of RC-RNase.

With the approaches of lifecycle, structurizing and prototype applied, the dynamic management subsystem for medical equipment is developed, and thus the management level and economic benefit can be improved.

OBJECTIVE:To select a technique for preparation of fluconazole for injection and to establish a method for determination of its content.METHODS:The formula was selected on the basis of pH value and species of solution adjuvant.The content was determined by HPLC.RESULTS:The preparation was stable when pH value was between6.5～8.5,and its clarity could be increased by propylene glycol.The detectable concentration of fluconazole showed a good linear correlation in the range of40～200?g/ml.The average recovery was100.37%,RSD=1.37%(n=3).CONCLUSION:The fluconazole for injection prepared by the present technique is stable in quality and the method for content determination is accurate and practicable.

Objective To review the effects of preventive management during the operation for post-operative chylothorax in patients with lung cancer of state Ⅲ. Methods Total 425 patients underwent pulmonary resection (at least lobectomy) and systematic mediastinal lymph node dissection for lung cancer of state Ⅲ from January 1998 to June 2005. Took some especial management during the operation to prevent post-operative chylothorax in 132 patients after March 2004. According to the surgical procedure,all patients were divided into preventive group and non-preventive group. Results There were 14 patients (4.8%) with post-operative chylothorax in the group of inchoate 293 patients before March 2004. Only 1 patient (0.07%) among 132 patients who underwent treatment for chylothorax during the operation after March 2004 had post-operative chylothorax (P

Objective To evaluate the technique of selective portal vein embolization before hepatectomy and its value in the preparation of major hepatic resection for those with insufficient future remnant liver.Methods From Jan 2008 to July 2012,6 patients who suffered from hepatic tumors underwent selective ipsilateral portal vein embolization (PVE) due to insufficient future remnant liver volume (FRLV) before second-stage major hepatic resection.Results Technically,all six PVE were completed successfully with only minor liver function damages.The average FRLV increased from (474.33 ± 89.19)cm3 to (722.67 ± 151.51) cm3 (t =-5.587,P =0.003).The average tumor burden (total tumor volume)increased from (134 ± 181) cm3 to (270 ± 346) cm3 (t =-1.64,P =0.16).Five cases underwent secondstage major hepatectomy 6 weeks after PVE,while in 1 case a resection attempt was abandoned because of uncontrolled tumor growth during the period.During the follow-up period (median 37 months),1 died,4 survived,2 were tumor-free.Conclusions Selective portal vein embolization is a safe and effective method to induce hepatic hypertrophy in the appropriate clinical setting.Before PVE,hepatic tumor should be controlled beforehand with chemotherapy or TACE to ensure the scheduled second-stage hepatectomy.
