Objective To investigate the surgical managements and effects of congenital islated penile curvature. Methods The degloving of penile shaft,penile dorsal tunical plication,urethral division and urethroplasty were performed in 23 patients with this entity including 2 cases of type Ⅰ,11 cases of type Ⅱ,6 cases of type Ⅲ,4 cases of type Ⅳ,mean age 7 years (age 1 to 21 years). Results Of all 23 patients 17 cases of type Ⅱ and Ⅲ were succesfully repaired by degloving of penile shaft;1 case of type Ⅰ,by degloving of penile shaft and dorsal tunical plication;1 case of type Ⅰ and 2 cases of type Ⅳ,by degloving of penile shaft,dorsal tunical plication and urethral division;2 case of type Ⅰ and Ⅳ,by urethroplasty.One case was complicated with urethrocutaneous fistula after urethroplasty,which was succesfully repaired 8 month later;16 cases were followed up average 24 months (range 7 months to 57 months),15 cases showed complete straight penis beside one case with mild curvature less than 15 degree. Conclusions The abnormalities of skin,dartos and Buck's fasciae are main causes of congenital islated penile curvature.Penile degloving,dorsal plication are main surgical methods with minimal complications.

ObjectiveTo evaluate the effect of increasing doses of tamsulosin in lower urinary tract symptom (LUTS) of benign prostatic hyperplasia (BPH).MethodsA prospective self-controlled clinical trail was performed.Two hundred and sixty-one patients who had LUTS of BPH were enrolled in this prospective 4 weeks study of tamsulosin.The patients were randomly divided into 2 groups:took tamsulosin 0.2 mg QN (n =126,group A) and 0.4 mg QN (n =135,group B) respectively.The IPSS score and maximum flow rate before and after treatment were compared between the 2 groups.ResultsThe IPSS score of group A decreased from 17.72 ± 2.50 to 10.21± 1.95,average decreased 7.59 ± 2.74 ； maximum flow rate was elevated from (8.78 ± 3.70) ml/s to ( 12.74 ± 2.99 ) ml/s,average increased (4.31 ± 3.01 )ml/s.The IPSS score of group B decreased from 19.24 ± 3.22 to 11.21 ± 3.02,average decreased 8.49 ±3.73； maximum flow rate was elevated from (7.74 ± 1.97) ml/s to ( 12.04 ± 2.46) ml/s,average increased (4.73 ± 2.97) ml/s.There was no significant difference of the changes of IPSS score between the 2 groups ( P ＞ 0.05 ),but there was a significant difference of the changes of maximum flow rate between the 2 groups ( P ＜ 0.05 ).The results was further analyzed by sub grouped ( by patient body weight,divided into ≤55.0 kg,55.1 -65.0 kg,65.1 -75.0 kg,＞75.0 kg group).There were significant differences of the changes of IPSS score and maximum flow rate between the 2 groups in 65.1 - 75.0 kg and ＞ 75.0 kg subgroups ( P ＜ 0.05 ).The incidence of side effects between the 2 groups was not significantly different (P ＞ 0.05).ConclusionsFor most patients,the use of high-dose tamsulosin in improving LUTS caused by BPH can not bring significant benefits.But if the patient's weight is more than 65.0 kg,increasing the dose of tamsulosin is suggested for consideration.

Objective To assess the clinical characteristics of primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL) and its treatment and prognosis. Methods Twenty patients diagnosed with PGI-DLBCL were admitted to hospital between 2003 and 2007. The clinical characteristics and tumor molecular model of PGI-DLBCL as well as therapeutic methods were retrospectively studied. The factors that related to survival and prognosis were statistically analysed.Results The overall survival (OS) time of the patients were from 42 months to 52 months,while the progression-free survival (PFS) time were from 37months to 47 months. The International Prognostic Index (IPI) score (0～2 or ＞2) played a reminding role in prognosis of the disease. Tumor molecular model was no effect on prognosis [that was no significant difference between germinal center B-cell-like (GCB) type and non-GCB type]. The efficacy of Rituximab in combination with CHOP chemotherapy (R-CHOP) in treatment of PGI-DLBCL was similar to CHOP chemotherapy alone, whereas surgical intervention might prolong survival period. Conclusions The biological characteristics of PGI-DLBCL is so particular that the most therapeutic method, which need to be further studied, would be different from DLBCL in other position.

Objective: Purpose to investigate the different in vitro function of targetable non-viral vector containing poly-L-lysine or protamine. Methods: Using GV1 and GV2 targetable non-viral vectors, the influences of the poly-L-lysine and protamine on in vitro gene transfer efficiency and the course of gene expression were observed. Results: ?-galactosidase was expressed at intermediate level (50% ) in A375 cells using a complex containing either protamine or poly-L-lysine. Howerver, in case of ABAE cells, ?－galactosidase expression level was low (20% ) transferred with a comPlex containing protamine. On the contrary, ?－ galactosidase expression was at high level (70% ) provided that protamine was replaced with poly-L-lysine. In addition, ?-galac- tosidase activity reached the peak at the 6th day after transfection with the complex containing protamine. The expression was not altered with subsequent subcultures, at least for 3 passages. Using poly-L-lysine, the expression peak in A375 reached the peak at the 7th day after transfection, but the level declined along with subsequent passages of cells. Conclusion: The apllication of protamine in VEGF receptor mediated gene delivery system was limited.

Objective To systematically evaluate the efficacy and safety of injected hemocoagulase Agkistrodon for intraoperative bleeding.Methods We electronically searched several Chinese database till May 2014 to identify randomized controlled trials (RCTs) about injected hemocoagulase Agkistrodon for operative hemorrhage.The methodological quality of included RCTs was assessed,and the data were extracted by two reviewers independently according to the Cochrane Handbook.The homogeneous RCTs were pooled using RevMan software (Version 5.1.0).Results 2 358 articles were searched initially,and 12 RCTs involving 1 031 patients met the inclusion criteria.The results of Meta-analyses showed that:in the study groups,the average haemostatic time of the wound is shorter [OR =-40.29,95％ CI(-71.13,-9.44),P =0.01],the hemorrhagic volume of the wound [OR =-1.38,95％ CI(-1.90,-0.87),P ＜ 0.000 01],hemorrhagic volume per unit area of the wound [OR =-0.05,95％ CI(-0.06,-0.03),P ＜ 0.00001],introperative hemorrhagic volume and drainage volume on POD1 [OR =-18.52,95％ CI (-25.50,-11.53),P ＜ 0.000 01] are lower than the placebo groups.In all studies,no difference was found in the variation of hemostatic function,liver and renal function and drug-induced adverse events.Conclusions The injection of hemocoagulase Agkistrodon can significantly reduce the average haemostatic time of the wound,the hemorrhagic volume of the wound,overall introperative hemorrhagic volume and drainage volume on POD1,and does not affect the hemostatic function,liver and renal function and not increase the incidence of adverse effects or postoperative complications.

Methods 80 cases of radical mastectomy for breast cancer treated in our hospital from January 2015 to January 2017 were treated with docetaxel combined with capecitabine chemotherapy. According to different nursing methods, the patients were divided into 2 groups. The observation group was treated with psychological nursing, while the control group received routine nursing care. The anxiety and depression scores in two groups before and after nursing were observed and compared. Results There were no significant difference in the scores of anxiety and depression between the two groups before and after treatment. After the intervention group, patients in observation group were significantly improved, and better than the control group patients; The nursing satisfaction rate in the observation group was 97.5%,which was significantly higher than that in the control group (72.5%) (P<0.05). Conclusion After radical mastectomy of breast cancer with docetaxel combined with capecitabine chemotherapy and psychological clinical observation of dry pre found in breast cancer resection and chemotherapy as the basis, to patients with psychological intervention can improve the clinical situation of patients, promote their mental status improved, improve nursing satisfaction rate of patients, so it is worthy of reference.

Objective To evaluate the effects of hypocaloric parenteral nutrition on metabolism and prognosis of aged post-traumatic patients. Methods The prospective randomized controlled study was designed. Twenty-four aged post-operative patients were divided into 2 groups: hypocaloric parenteral nutrition group (Caloric 15 kcal?kg -1?d -1/Nitrogen 0.1 g?kg -1?d -1 ) and traditional parenteral nutrition (Caloric 28 kcal?kg -1?d -1/Nitrogen 0. 2 g?kg -1?d -1), respectively. Serum glucose, protein, and lipid levels, infection-related complications, nutrition therapy hospital expenses, hospitalization duration after operation were analysed. Results During nutritious fluid transfusion at 1-5 days after operation, nutrition therapies, serum glucose level of hypocaloric group was obviously lower than that of the traditional group 〔(6.8?0.3) mmol L -1 vs (8.3?0.4) mmol?L -1 , P

Objective To evaluate the surgical treatment of carotid artery stenosis. MethodAccording to the level and degree of the stenosis, different operations were performed on 120 patients who suffered from the extracranial carotid stenosis. Treatment result was retrospectively reviewed. ResultSurgery was successful in all the patients. We performed carotid endarterectomy on 111 cases and other operations on 9 cases. The incidence of postoperative complications was low, especially for carotid endarterectomy. ConclusionCarotid endarterectomy is still the main therapy for the treatment of carotid artery stenosis with a satisfactory result.

Aim To investigate apoptosis induced by 3,3'-diethyl-9-methylthia-carbocyanine iodide(DMTCCI) , an inhibitor of DNA primase found in our previous study, and the mechanism of DMTCCI in human myelogenous leukemia HL-60 cells. Methods HL-60 cells were cultured in RPMI-1640 medium and treated with different concentrations of DMTCCI. MTT assay was used to detect growth inhibition.Flow cytometry and DNA ladders were used to detect apoptosis. Western blotting was used to observe the expression of survivin, Bcl-xL, Bad, Bax, Bcl-2, caspase-9, caspase-3, caspase-6, PARP, DFF45 and lamin B protein. Caspase-3 activity was measured by ApoAlert Caspase-3 Assay Kit. Results DMTCCI inhibited proliferation of human leukemia HL-60 cells with IC50 value of 0. 24 μmol · L-1. The results of flow cytometry and DNA ladders showed that DMTCCI could induce apoptosis of HL-60 cells. The expression levels of protein survivin and Bcl-xL were down-regulated, Bad and Bax were up-regulated,while Bcl-2 protein had no change in response to DMTCCI treatment in HL-60 cells. Treatment of HL-60cells with DMTCCI induced the proteolytic cleavage of caspase-9, caspase-3, caspase-6, PARP, DFF45and lamin B protein. Caspase-3 activity apparently increased at 3 h and reached a peak at 12 h after exposure to 1 μmol · L-1 of DMTCCI in HL-60 cells. Conclusion DMTCCI inhibited proliferation and induced apoptosis of human leukemia HL-60 cells. Bcl-2 family proteins, survivin and caspases family proteins might playa role in the apoptosis process induced by DMTCCI.
