Lower urinary tract symptoms (LUTS) resulting from benign prostatic hyperplasia (BPH) obviously impair the quality of life of middle-aged and elderly men. Current management of BPH includes wait-and-watch, medical therapy, and conventional surgery. As a new approach, minimally invasive surgery has been playing an increasingly important role in the management of BPH, with potential advantages of less operative trauma, quicker recovery, lower risk of postoperative complications and higher quality of life. This review mainly discusses prostatic urethral lift (Urolift® System), transurethral water vapor therapy (Rezūm® System) and robot-guided high-energy water ablation (PROCEPT Aquablation™ System).

OBJECTIVE:To investigate the effect of rapid rehabilitation surgery assisted to fluorouracil,oxaliplatin,leucovo-rin(FOLFOX)on postoperative recovery,complications and quality of life in patients with colorectal cancer. METHODS:60 pa-tients with colorectal cancer were randomly divided into control group(30 cases)and observation group(30 cases). After resection of colorectal cancer,control group received 85 mg/m2 Oxaliplatin for injection,2 h intravenous infusion,d1+200 mg/m2 Calcium le-vofolinate for injection,intravenous infusion,once a day,d1-2+400 mg/m2 Fluorouracil injection,intravenous infusion,once a day, d1-5 then 600 mg/m2 for 22 h intravenous infusion,d1-2. Observation was additionally given rapid rehabilitation surgery. 2-week was regarded as 1 course,it lasted 12 courses. Urinary retention time,anal exhaust time,first defecation time,postoperative hospital-ization time,scores of life quality (overall health,emotional function,mental health,physiological functions,physical function,so-matic pain,vitality,social function)in 2 groups were observed,and the incidence of postoperative complications was recorded. RE-SULTS:The urinary retention time,anal exhaust time,first defecation time,postoperative hospitalization time in observation group were significantly shorter than control group,the incidence of postoperative complications in observation group was signifi-cantly lower than control group,overall health,emotional function and mental health score were significantly higher than control group,the differences were statistically significant(P<0.05),but there were no significant differences in physiological functions, physical function,somatic pain,vitality,social function score in 2 groups (P>0.05). CONCLUSIONS:Rapid rehabilitation sur-gery assisted to FOLFOX chemotherapy can reduce the incidence of postoperative complications in patients with colorectal cancer, improve quality of life,shorten hospitalization time and promote postoperative recovery.

Objective To package the recombinant lentivirus containing HIV-1 Vpr gene and detect the effect of Vpr protein expression on the latent infection and lyric replication of KSHV.Methods The fragment of Vpr gene from expression plasmid pCI-neo-Vpr was cloned into the lentivirus vector pHAGE-CMV-MCS-IzsGreen,then the recombinant plasmid pHAGE-Vpr,package vector psPAX2 and envelope vector pMD2.G were cotransfected into 293T cells.GFP expression was observed by fluorescent microscopy.Culture media of 293T cells were harvested and filtered through 0.45 μm filter.After 293T cells were infected by a series of diluted lentivirus,the virus titer was checked by observing GFP expression.Vpr mRNA transcripts in 293T cells were detected by RT-PCR.Then BCBL-1 cells were infected by the recombinant lentivirus with 1 MOI,GFP expression was observed by fluorescent microscopy,and the mRNA transcripts and protein expression of Vpr in BCBL-1 cells were detected by RT-PCR and Western blot.Meanwhile,the mRNA transcripts and protein expression of KSHV lytic cycle gene Rta were detected by RT-PCR and Western blot,respectively.Results The recombinant lentivirus carrying HIV-1 Vpr was packaged successfully with the virus titer of 4 × 107 TU/ml.After infected with lentivirus,BCBL-1 cells could express GFP,and the exact band of Vpr was detectable by RT-PCR and Western blot.Moreover,the expression of KSHV Rta mRNA and protein were downregulated by Vpr protein.Conclusion Overexpression of HIV-1 Vpr mediated by the recombinant lentivirus could inhibit KSHV lytic replication and enhance KSHV latent infection.

Objective To explore the clinical characteristics of nosocomial infection in children with acute leukemia and the strategy of prevention and treatment.Methods One hundred and thirty-three cases of nosocomial infection in children with acute leukemia were analyzed by retrospective study.The relationship between nosocomial infection and stage of leukemia,hospitalization duration,and the rate of infection were investigated.Results Nosocomial infection rate was 53.4%(71/133 cases),significant difference of infection rate between acute lymphoblastic leukemia and nonlymphoblastic leukemia group was found(P0.05).The main pathogens of septicaemia were gram negative bacilli,and they were generally sensitive to Amicacin and Pi-peracillin/tazobactam.Conclusions Children with acute leukemia have high nosocomial infection rate.The occurrence of nosocomial infection was related to the type and stage of leukemia and hospitalization duration but not to the prognosis.The main pathogens of septicaemia were gram negative bacilli.

A vernier optometer, based on the Scheiner principle, that makes use of polarized light, is designed and developed. It is specialized in measurement of tonic accommodation, accommodation and accommodation response. The vernier optometer has been proved by chinical testing results, to be a reliable and effective instrument with fine stabilily, good repeatability and sensitivity for short sight study relating to oculogyral parameters.

Objective To analyze the influence of age on the diagnosis of acute heart failure (AHF) with amino terminal brain natriuretic peptide (NT‐proBNP) ,and to explore the best cut‐off value of NT‐proBNP in the diagnosis of AHF .Methods Totally 457 inpatients suspected with AHF obtained a blood NT‐proBNP measurement within 24 hours when in charged ,including 194 patients with AHF .Patients were divided into three groups according to their age :≤50 years ,>50-70 years and >70 years . The relationship between NT‐proBNPand AHF was analyzed .The diagnostic value of NT‐proBNP was evaluated for AHF in differ‐ent age groups .Results The median NT‐proBNP levels of AHF in all age groups were significantly higher than those without (P<0 .01) .AUC of NT‐proBNP for AHF in ≤50 years ,>50-70 years and >70 years groups were 0 .95 ,0 .91 ,0 .88 ,the best diagnos‐tic cut‐off points were 1 100 ,1 800 ,3 000 pg/mL ,respectively .The diagnostic specificity was 88% ,76% and 73% ,respectively .O‐verall ,the specificity of NT‐proBNP cut‐off values for age group was higher than non‐age groups .Conclusion NT‐proBNP has a good value in the diagnosis of AHF in patients with different ages .According to the age group ,the different NT‐proBNP cut‐off values can be used to improve the specificity of diagnosis .

Objective To evaluate short-term curative effect of endovascular abdominal aortic aneurysm repair. Methods Twelve cases of infra-renal abdominal aortic aneurysms were checked. Results The av-erage bleeding in the operation was 245 millimeter, the avenage hospitalization time was 8.6 days, and the average abrosia time was 1.5 days. White blood cell, hemoglobin, thrombocyte, hepatic function, and renal function were in the normal limits. Prothrombin time and activated partial thromboplastin time were post-poned after operation, and recovered normally within one week. Complications of operations were as follows:1 case of pulmonary infection, 2 cases of abdominal distention, and 1 case of intraoperafive endoleak. The former two kinds of complications alleviated after conventional treatment, and the latter disappeared naturally after 3 months. Conclusion Endovascular abdominal aortic aneurysm repair is safe, mini-invasive, and has little disturbance for body internal environment.
