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).

A)at nt.41 of the only one repeat in 15 individuals with the A205 allele were detected.No special molecular background was found in the two samples which were phenotyped as A2,but genotyped as A102/B101.Conclusion CBF/NF-Y enhancer region of the A2 alleles occurs with minisatellite fragments length polymorphisms.Allele-specific variations in CBF/NF-Y enhancer region of A2 blood group gene were elucidated in Chinese population.

Objective To investigate the differences of low frequency fluctuation (ALFF)in the resting state between short-term heroin and methamphetamine abusers after withdrawal.Methods Sixteen male short-term heroin abusers and fourteen male short-term methamphetamine abusers were performed the functional magnetic resonance imaging (fMRI).The differences of ALFF be-tween the two groups were performed with preprocessing softwares.Threshold was set to 0.05.Results Compared with metham-phetamine-dependent patients,heroin-dependent patients showed increased ALFF in the left side of the lingual gyrus and the left ton-sil of cerebellum and decreased ALFF in the left side of the brain stem,midbrain and the left side of the cerebellar vermis.Conclusion There are differences between the short-term heroin and methamphetamine abusers in the function of the brain,mainly involving the brain regions associating with cognition and affection.

Objective To investigate the calcium signal transduction pathway in hippocampal neurons of mice with vascular dementia (VaD) and the intervention effect of dihydroergocriptine (DHE). Methods The mice were subjected for ischemia-reperfusion repeatedly on bilateral common carotid arteries by knots to establish the VaD models. Animals with sham-operation were taken as control group. The treating group was administered with DHE after the establishment of VaD model. The behavior changes were observed through the step-down avoidance test and water maze test on the 29th and 30th days after operation. The resting 〔Ca 2+〕 i level of hippocampal neurons was evaluated by laser scanning confocal microscopy. RT-PCR technique was used to measure mRNA expression of CaM an CaMPKⅡ in hippocampal neurons. Results The resting 〔Ca 2+〕 i level in model group(43.50?3.00) was significantly higher than those in the sham-operation group (25.50?3.50) (P

Objective To investigate the efficacy of autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis. Methods A 21-year-old patient with dermatomyositis received autologous peripheral hematopoietic stem cell transplantation and was followed up for 6 years. Autologous peripheral hematopoietic stem cells were mobilized by recombinant human granulocyte colony stimulating factor (rhG-CSF) before the transplantation, and the conditioning regimens consisted of cyclophosphamide,methylprednisolone and cyclosporin. Rabbit anti-human T lymphocyte immunoglobulin began to be applied on day 3 after retransfer of stem cells. The improvement in symptoms, physical signs and biochemical indicators was observed, and hematopoietic restructuration and immunity resurrection were evaluated after the transplantation. Results After the transplantation, skin eruption greatly improved and gradually subsided. The muscle force of extremities restored from level Ⅳ before transplantation to level Ⅴ. The level of creatine kinase declined sharply after transplantation, but gradually returned to previous level. Leucocyte count began to decrease on the day of retransfer, and returned to the normal level on day 8. Immune function remained normal before and after the transplantation. Conclusion Autologous peripheral hematopoietic stem cell transplantation is an alternative treatment for severe and refractory dermatomyositis.

Objective To study the CT findings of small thyroid carcinoma. Methods The CT findings of 40 patients with histology-proven small thyroid carcinoma (diameter, 1.0 to 2. 0 cm) were retrospectively reviewed. Results (1)The single lesion was detected in 38 cases and two lesions in bilateral thyroid in 2 cases. Two cases were combined with contralateral nodular goiter and I case with contralateral thyroid adenoma. ( 2 ) Eight lesions showed smooth edge and complete envelope. Thirty-four lesions demonstrated foggy edge and incomplete envelope,but they didn't invade the surrounding soft tissues and important organs. ( 3 ) The density of all lesions were homogeneous or comparatively homogeneous without obvious hemorrhage or necrosis area on non-enhanced CT. Thirty lesions showed varied shape calcifications,with granular calcifications in 20 lesions being the most common. Irregular nodular,eggshell-like or mulberrylike calcifications were also detected. (4)Forty-one lesions showed marked enhancement on post-contrast CT and the amplitude of enhanced CT value was greater than 40 HU(range,90 to 140 HU). Thirty-eight lesions exhibited homogeneous enhancement, and other 3 lesions showed marked enhancement center with a ring-like low density edge and manifested as a characteristic damascene-like appearance. (5)Enlarged cervical lymph nodes were found in 24 cases ( 60. 0% ), which displayed solid, cystic-solid or cystic appearances on nonenhanced CT. They showed markedly homogeneous,irregular ring or wall-node enhancement on post-contrast CT. In 8 cases there were granular, nodular or eggshell-like calcifications within the enlarged lymph nodes.Conclusion A solid thyroid nodule with granular calcification, incomplete envelope and marked enhancement, companied with enlarged lymph nodes with calcification, cystic degeneration and obviously enhanced solid part are the relatively characteristic CT features of small thyroid carcinoma.

Objective To explore the management of benign prostatic hyperplasia(BPH)by photoselective vaporization of prostate(PVP)and curative effect in the near future. Methods Clinical data of 60 BPH patients underwent PVP were retrospctively aralyzed.The changes of IPSS and QOL and the max urine flow rate and residual urine volume(RUV)perioperatively were compared through observations of the operation time and complication. Results The therapeutic efficacy was favourable.No transurethral resection of prostate(TURP)syndrome and uroclepsia happens.IPSS(t=2.471,P <0.05)and QOL(t=2.392,P <0.05)and the max urine flow rate(t=2.287,P ＜0.05)and residual urine volume(t=2.513,P＜0.05)obviously improved(P ＜0.05). Conclusion PVP had many advantages such as operated simply and no serious complications.It was a good operation method to treat BPH.

Objective To compare clinical effects of appendicectomy and conservative treatment of uncomplicated acute appendicitis.Methods Searched The Cochrane library,Medline,Pubmed,Embase,CBM,CNKI,VIP and Wan Fang database in any language.RCTs that compared conservative treatment with appendicectomy in patients with uncomplicated acute appendicitis were included from January 1983 to May 2013 and qualities of the trials were evaluated.Statistic analyses were carried out using RevMan 5.1 soft-ware.Results Four randomized trials met our inclusion criteria (821partiCI:pants).Antibiotics compared with appendicectomy resulted in similar outcomes with regards to the incidence of complicated appendicitis (RR:0.89,95％ CI:0.29-2.68) and intra-abdominal infection(RR:0.54,95％ CI:0.13-2.35).Antibiotics carries a lower risk of complications (RR 0.46,95％ CI:0.32-0.67),but requires more length of hospital stay (Mean Difference 0.52,95％ CI:0.16-0.88).Conclusions The effect of conservative treatment is safe and effective.But the recurrent uncomplicated appendicitis recommends operation.

Objective To compare the pros and cons of endoscopic papillary balloon dilation (EPBD) with those of endoscopic sphincterotomy (EST) in the treatment of common bile duct stones.Methods We searched The Cochrane library,Medline,Pubmed,Embase,CBM,CNKI,VIP and Wan Fang database in any language.RCTs that compared EPBD with EST for the removal of common bile duct stones were included from January 1983 to September 2012 and qualities of the trials were evaluated.Statistic analyses were carried out using RevMan 5.1 software.Results A total of 18 randomized trials with 2385 participants met our inclusion criteria.EPBD compared with EST resulted in similar outcomes with regards to stone removal on 1 st attempt,overall stone removal,perforation,total short-term complication,long-term cholangitis or mortality.EPBD carries a higher risk of pancreatitis (RR =1.99,95％ CI:1.41-2.81) and severe pancreatitis (RR =4.68,95 ％ CI:1.36-16.11),and requires higher rates of mechanical lithotripsy (RR =1.31,95％ CI:1.14-1.50).Conversely,EPBD not only has statistically significant lower rates of bleeding (RR =0.14,95％ CI:0.06-0.34),but also leads to significantly less long-term cholecystitis (RR =0.38,95％ CI:0.19-0.76),long-term stone recurrence (RR =0.67,95％ CI:0.47-0.96) and total longterm complications (RR =0.52,95 ％ CI:0.40-0.67).Conclusion On the basis of lower rates of bleeding or long-term complications,EPBD should be the preferred strategy over EST for endoscopic management of common bile duct stones,however,the rate of pancreatitis,especially the severe pancreatitis is higher with EPBD.
