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.

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 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

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 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 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

Objective To carry out the current status of internal quality control by statistical analysis of the Internal Quality Control (IQC)data of homocysteine in 2014 March.Methods Web-based External Quality Assessment (EQA)system was used to collect IQC data of homocysteine from 292 EQA participant laboratories nationwide.The data include thecoefficient of variation (CV)of IQC data under control in March 2014 and long-term cumulative data.Acceptable rates of CVs of two-lot internal quality controls in homocysteine were calculated according to 5 criteria,that were 1/3TEa,1/4TEa and the speci-fications based on biological variation including the minimal,appropriate and optimal allowable imprecision.The instrument the participant laboratories used were sorted into 6 groups and the passing rate of each group were calculated by the 5 crite-ria.Results 292 laboratories reported the data of level 1 IQC for homocysteine,106 of which reported the data of level 2 IQC.The passing rate was different according to different criteria.The passing rate had few difference by the criteria of 1/3TEa and the minimal allowable imprecision based on biological variation,which were from 63.36% to 76.42%.It was also true for 1/4TEa and the appropriate allowable imprecision based on biological variation,which were from 34.25% to 57.55. The passing rate was only 10.62%~16.98% by the criteria of appropriate allowable imprecision based on biological varia-tion.Statistical results showed that instruments the participant mainly used were HITACHI (77/292),Olympus (61/292), Roche (19/292),Beckman (14/292),Abbott (10/292)and Simens (10/292).The passing rates of all the instrument group had few difference except Simens group.Conclusion Most of the laboratories could meet the criteria of 1/3TEa and the min-imal allowable imprecision based on biological variation.But less than half of the laboratories could meet the criteria of 1/4TEa and the appropriate and optimal allowable imprecision based on biological variation.The precision performance of ho-mocysteine among laboratories needs further improvement.
