Hamilton Rating Scale for Depression was taken to evaluate efficacy score. Results At the end of six weeks,compared with the total scores of HAMD before and after treatment, escitalopram (17.5±7.8) and paroxetine (16.0±7.9) group both showed the significant difference, while the difference compared between two groups ,the efficacy (87.0% and 81.7%) for depression and side effects were no significance. Conclusion Escitalopram is an efficient and safety antidepressant.

OBJECTIVE:To observe clinical efficacy and safety of linezolid,teicoplanin and vancomycin in the treatment of hospital-acquired pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA). METHODS:120 patients diagnosed as hospital-acquired MRSA pneumonia were divided into linezolid group,teicoplanin group and vancomycin group according to therapeutic regimen,with 40 cases in each group. Linezolid group received Linezolid injection 600 mg,ivgtt,bid;teicoplanin group received Teicoplanin injection 0.4 g,ivgtt,bid;vancomycin group received Vancomycin injection 1 000 mg,bid,ivgtt. 3 groups received 2 weeks of treatment. Clinical efficacy and bacterial clearance effective rate of 3 groups were observed as well as serum levels of inflammatory factors before and after treatment. ADR of 3 groups were compared. RESULTS:The clinical effective rates of linezolid group,teicoplanin group and vancomycin group were 90.0%,72.5% and 67.5%;the effective bacterial clearance rates were 85.0%,60.0% and 57.5%,respectively. The clinical effective rate and the effective bacterial clearance rate in linezolid group were significantly higher than those in teicoplanin group and vancomycin group,with statistical significance (P<0.05). There was no statistical significance in above indexes between teicoplanin group and vancomycin group (P>0.05). There was no statistical significance serum inflammatory factors among 3 groups before treatment (P>0.05). CRP and PCT of 3 groups de-creased significantly after treatment,and those of linezolid group were lower than teicoplanin group and vancomycin group,with statistical significance(P<0.05). There was no statistical significance in serum inflammatory factors between teicoplanin group and vancomycin group before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR among 3 groups (P>0.05). CONCLUSIONS:For hospital-acquired MRSA pneumonia,linezolid is better than teicoplanin and vancomycin in pneumonia control with good safety.

Objective To study the effect of Sirtuin1 (Sirt1) on the pathological process through its activity of deacetylation to improve the clinical outcome of acute sepsis. After searching data base, microRNA-211 (miR-211) was found to have action potentially targeting at Sirt1.The present study aimed to find the interaction between miR-211 and Sirt1 in the pathogenesis of hypoxic injury to cardiomyocytes in the presence of lipopolysaccharide ( LPS ) . Methods Primary neonatal rat cardiomyocytes ( NRC ) isolated from neonatal SD rats and H9c2 ( cardiomyocytes after culture with 10% fetal serum of cattle and DMEM under 37 ℃ and 5% CO2 ) cell line were used in the experiments.The miR-211 expression was quantified by qRT-PCR after LPS exposure for 4 hours, and the changes in Sirt1 protein level were also detected in both NRC and H9c2 by western blot.At the same time, CCK-8 assay and TUNEL staining were also performed to measure cell proliferation and apoptosis activation when either treated with LPS alone or followed by exposure to hypoxia.Results Compared to the control group, the doses of 20μg/mL, 40μg/mL LPS treatment for 4 hours had no significant effects on H9c2 cell proliferation at 24 h, 48 h, 72 h, but it could significantly induce the cell apoptosis of neonatal rat cardiomyocytes and H9c2 cells after hypoxia, and the apoptosis rate increased all over 100% in both NRC and H9c2.At the same time, LPS treatment could significant up-regulate miR-211 expression which was closely associated with decrease in Sirt1 protein levels.Conclusions LPS enhanced cardiomyocytes injury after exposure to hypoxia which was closely associated with up-regulating miR-211 expression and in turn to suppress Sirt1 expression.

Objective To observe the therapeutic effect of ai-weizhi on anterior ischmic optic neuropathy (AION). Methods In 58 patients (60 eyes) who were diagnosed as with AION, 29 patients (30 eyes) underwent intravenous drip with ai-weizhi (1 200 mg/d) (treatment group), and the other 29 patients (30 eyes) underwent intravenous drip with 1-2 kinds of thrombolytic coagulant or vasodilator (once per day) (control group) with the period of treatment of 15 days. In the control group, ocular local injection, including gluco-corticosteroid and 654-2 behind or beside the eyeball injected once per day or every 2 days for 3-5 times, was perfomed on 20 eyes simultaneously. The changes of visual acuity and ocular fundus of the patients after injection were recorded, and the visual field was counterchecked in the patients who had underwent the examination before the treatment. Results The visual acuity was better in treatment group than which in control group with a significant difference (t=2.74, ?0.05). At the 5th、 10th and 15th day after treatment, the visual acuity was better in treatment group than which in control group with a significant difference(t=2.01, P

OBJECTIVETo compare the effectiveness and safety of transurethral resection of the prostate (TURP) and transurethral enucleative resection of the prostate (TUERP) in the treatment of benign prostate hyperplasia (BPH).

METHODSA total of 630 BPH patients with indication of surgery were randomly assigned to receive TURP (n = 305) and TUERP (n = 325), respectively. There were no significant differences preoperatively in age, prostate volume, International Prostate Symptom Score (IPSS), and Qmax between the two groups (P > 0.05). The prostate resection rate, operation time, postoperative complications, and quality of life (QOL) of the patients were recorded and statistically analyzed.

RESULTSCompared with TURP, TUERP showed a significantly higher rate of prostate resection ([47.0 +/- 13.3] vs [60.1 +/- 12.3]%, P < 0.05), shorter operation time ([57.9 +/- 15.9] vs [40.4 +/- 14.2] min, P < 0.05), and shorter bladder irrigation time ([2.7 +/- 0.6] vs [2.2 + 1.1] d, P < 0.05). Significant differences were found between the pre- and post-operative levels of serum sodium and hemoglobin in the TURP group ([141.2 +/- 3.5 ] vs [136.9 +/- 4.7] mmol/L, P < 0.01; [137.6 +/- 8.8] vs [124.8 +/- 9.6] g/L, P < 0.01), but not in the TUERP group. Three months after operation, IPSS, QOL, and Qmax were all markedly improved in both groups (P < 0.01), but with no significant differences between the two groups (P >0.05).

CONCLUSIONTUERP is better than TURP in the treatment of BPH for its advantages of higher resection rate of the prostate, shorter operation time and bladder irrigation time, less intraoperative blood loss, fewer postoperative complications, and faster recovery.

Objective To investigate the relationship between myeloperoxidase(MPO) and ankle brachial index(ABI) in patients with htypehypertension.Methods A total of 133 patients were enrolled in this study,and divided in to htypehypertention group(n=72),non-htypehypertension group(n=30) and normotension group(n=31).Their Hcy,ABI and MPO levels were measured and compared.Results The ABI in htypehypertention group and non-htypehypertension was significantly lower than that in normotension group (P<0.05),ABI in non-htypehypertension group was lower than that of htypehypertonsion group(P<0.05).MPO and CRP in the htypehypertension group was significant higher that those of normotension group(P<0.05).The ABI was negatively related with the serum MPO and CRP levels in htypehypertention group (r=-0.712,-0.722,P<0.05).Conclusion ABI is closely related with MPO,and play an important role in diagnosis of artery function impairment and high risk of htypehypertension patients.

Objective: To evaluate the protective effect of epidermal growth factor (EGF) on intestinal barrier functionin rats with acute pancreatitis. Methods: Thirty-two male SD rats received injection of sodium taurocholate solution(3. 5 mg?L-1) into the pancreatic duct were randomly divided into control group (n=16) and treatment group (n=16). Animals incontrol group received total parenteral nutrition (TPN), animals in treatment group were fed on the same TPN formula ascontrol group and injections of EGF at a dose of 0. 2 mg' kg l' day--'. Rats were sacrificed on d 1 and d 5 of TPN. Concen-tration of xylose and fluorescein isothiocyanate (FITC)-dextran in superior mesenteric vein (SMV), protein and DNA contentin je junal mucosa were determined. Samples from SMV, mesenteric lymph nodes, pancreas, liver, spleen were harvested forcultures. Results: FITC-dextran concentration in treatment group was significantly lower than in control group [(3. 4?0. 7)vs (7. 5?0. 9) mg. L-1, P＜0. 0l]. Protein and DNA content in je junal mucosa in treatment group were significantly higherthan in control group [(2. 65?0. 23) vs (1. 12?0. 18) mg? cm-1, (0. 25?0. 07) vs (0. 12?0. 04) mg?cm-1, P
