OBJECTIVETo investigate the feasibility and effect of early removal of the urethral catheter after transurethral plasma kinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe equally randomized 128 BPH patients treated by PKRP to an experimental group and a control group, urethral catheters removed at 1 -2 days for the former and at 5 -7 days for the latter. We compared the relevant indexes and clinical effects between the two groups.

RESULTSThe baseline data were not significantly different between the two groups. Compared with the controls, the experimental group showed a significantly shorter postoperative hospital stay ([6.8 +/- 1.9] d vs [3.7 +/- 1.5] d, P < 0.05) and lower infection rate (25.0% vs 10.9%, P < 0.05). All the patients were followed up for 3 -6 months postoperatively. At 3 months after surgery, both the experimental and the control groups showed remarkable improvement in the International Prostatic Symptoms Scores (4. 9 +/- 2. 2 vs 5. 3 +/- 2. 3), maximum urine flow rate ([21.5+/- 5.6 ] ml/s vs [19.1 +/-4.9 ] ml/s) , and residual urine ( [ 16.8+/- 10.3 ] ml vs [18.9 +/- 12.3 ] ml), but with no significant differences between the two (P > 0.05) , and no significant differences were observed in postoperative complications (P >0.05).

CONCLUSIONEarly removal of the urethral catheter after PKRP, with its advantages of shorter postoperative hospital stay, lower infection rate, and no influence on the long-term effect, deserves to be recommended as a routine method in the treatment of BPH.

The conception of evidence-based medicine (EMB) has a strong influence on the medical world since it built up.This concept has been widely used in all sorts of clinic and basic medical research,however,it is little reported to be practised in our fundamental medical education.As for it,this article will briefly analyze the importance of introducing the idea into fundamental medical education,and for one thing,suggest some more reform measures for medical teaching staff.

Objective To observe the effect of sitagliptin combined with insulin aspart 30 in the treatment of secondary failure of sulphonylurea in type 2 diabetes mellitus. Methods Fifty-six cases were divided into group A and group B in random block design, with 28 cases of each group. The patients in group A was treated with sitagliptin combined with insulin aspart 30, while the patients in group B was given subcutaneous injection of insulin aspart 30R. All patients were treated for 12 weeks. Fasting plasma glucose(FPG), 2-hour postprandial plasma glucose(2 hPG), glycosylated hemeglobin(HbA1c), insulin secretion index (HOMA-β), body mass index (BMI), and incidence of low blood glucose before and after treatment were compared. Results Compared with that in group B, FPG [(5.61 ± 1.14) mmol/L vs. (7.8 ± 1.22) mmol/L], 2 hPG [(7.62 ± 1.35) mmol/L vs(9.72 ± 1.41) mmol/L] and HbA1c [(7.11 ± 0.83)%vs.(8.32 ± 1.04)%] in group A had a significant decrease;HOMA-β[(50.31 ± 5.12) vs. (41.86 ± 4.53)] of group A was higher than that of group B (P

An acidic xylanase gene,named xyl3,was cloned from the genomic library of enviromental microbes constructed by using shotgun cloning strategy,and submitted to GeneBank with accession number of gb:AY300805.BLAST analysis indicated that the gene xyl3 has low similarity with other xylanase genes and the encoded xylanase,sorted as Glycosyl hydrolases family 10,has 77% similarity with the intra-cellular xylanase from Geobacillus stearothermophilus at amino acid level.Treated with T4 DNA polymerase,the gene xyl3 was ligated with the linearized Pichia pastoris expression vector pHBM905 produced by digestion of restriction endonuclease CpoI and NotI to generate the recombinant plasmid pHBM706.Then the plasmid pHBM706,digested by restriction endonuclease SalI,was transformed into P.pastoris GS115 to obtain the recombinant P.pastoris GS115(pHBM706),which was induced to produce the recombinant xylanase with 0.5% methanol at 28℃.At the 36th hours of induction,the porduced crude enzyme was detected to reach the higest enzyme activity of 0.177 IU/mL.The optimal pH and temperature of the enzyme activity is 5.5 and 50℃ respectively.

Objective To observe the clinical efficacy of improved Gudaofang at different concentrations for the treatment of soft tissue damage so as to determine its optimal concentration.Methods 150 patients with open soft tissue damage treated in our hospital from June 2014 to June 2016 were randomly divided into treatment Group A (n=40) and Group B (n=40), Group C(n=30)and control Group D (n=40).Group A, Group B and Group C were treated with 10%, 20%, 30% of improved Gudaofang respectively, while the control Group D was treated with 75% of alcohol.Its clinical efficacy was evaluated by tenderness score and swelling degree.Results Compared with post-treatment, different concentrations of improved Gudaofang significantly reduced the tenderness score and swelling degree (P<0.05).The total effective rate of Group A, Group B, Group C were 92.5%, 97.5% and 97.5%, respectively, were significantly better than the control Group D with 77.5% (P<0.05).Conclusion Different concentrations of improved Gudaofang has a certain clinical efficacy on treating open soft tissue damage.20% concentration of improved Gudaofang has the best cost-effective and is optimal drug concentration.

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.
