Prostate cancer is a common malignancy that affects men's health in the Western countries. Single nucleotide polymorphisms (SNPs), as the third generation of genetic markers, can influence the development, progression, and prognosis of prostate cancer. The same SNP may be related differently with prostate cancer among different races. This paper describes the relationship between SNPs and prostate cancer according to their related genes. SNPs can predict the risk of prostate cancer as well as the possible adverse reactions in its treatment, but at present they do have some limitations.

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.

Background The retina microglia play a eliminating effect on apoptotie cells in the neural retinal layer of normal rats during postnatal development.Milk fat globule epidermal growth factor 8(MFG.E8)can combine specifically with phosphatidylinositol serine of the surface of apoptotie cells and enhance macrophage phagoeytosis of apoptotic cells.Objective Present study was to evaluate the localization and expression of MFG-E8 and its relevant cytokines in the neural retinal layer of normal rats during postnatal development Methods Normal royal college of surgeon(RCS)rats were divided into P0,P3,P7,Pi4,P30,P45 groups according to their postnatal days,and the 30-day-old RCS rats(2 rats)served as controls.Double stain of M FG.E8 and microglial cells marker(CD11b)was performed by immunofluorescence.Expressions of MFG-E8,integrin β5,CD11b and interleukin-6(IL-6)mRNA in the neural retina were analyzed by real-time quantitative reverse transcription polymerase chain reaction(RT-PCR).The utilization of animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State and Science and Technology Commission.Results MFG-E8 and CD11b were positively co-expressed in retinal ganglion cell layer and external plexiform layer with the green fluorescence for FITC-labeled IgG and red fluorescence for cy3-labeled lgG respectively in normal adult rats.RT-PCR showed that the mRNA of MFG-E8,integrin 85,CD11b and IL-6 was detectable at P0 rats.The expression level of these eytokines began to rise fterward and reached peak value at P14 rats and then declined gradually,showing significant differences among different ages groups in various cytokines mRNA expression(all P<0.05).Conclusion MFG-E8 can be specifically expressed in the neural layer of retina microglia in RCS rat.

Objective To observe the influence of local-anaesthetic combined with dezocine on brachial plexus block and postoperative analgesia.Methods 60 patients scheduled for unilateral upper limb operation were randomly divided into two groups of C group and D group with 30 cases in each group.The brachial plexus block was performed under ultrasound guiding.Two groups received a bolus injection of local anesthetic 30ml,but the local bolus injection of D group consisted of Dezocine 10mg.The tine of sensory blocked producing effect,anesthesia effect,sensory blocked duration were observed.Two hours after sensory nerve recovered,the scores of VAS pain and Ramsay Sedation were recorded.Adverse reactions of perioperation were also observed(nausea,vomiting,dizzy,respiratory,urine retention,pruritus).Results The sensory blocked duration in D group was(7.1±1.1)h,which was significantly longer than that of C group[(4.5±0.8)h](t=10.47,P＜0.01);Two hours after sensory nerve recovered,the score of VAS pain in D group was(1.7±0.7)points,and significantly lower than that of C group[(3.9±1.0)points](t=9.87,P＜0.01).Both two groups had no adverse reactions.Conclusion Addition dezocine 10mg to local anesthetic solutions for interscalene brachial plexus block,it could prolong the sensory block duration,provide satisfactory postoperative analgesia,have no adverse reactions.

Objective To investigate the useful parameters of transthoracic echocardiography (TTE) for the diagnosis of stroke subtypes in patients with acute cerebral infarction.Methods One hundred and one acute ischemic stroke patients met all of the following criteria including ≥50 years of age,normal sinus rhythm on admission,and transesophageal echocardiography (TEE) within 7 days from the onset.The clinical significance of the TEE parameters on admission was examined for identifying intracardiac thrombus formation as follows; left atrial dimension,left ventricular end-diastolic dimension,percentage fractional shortening,left ventricular mass index,ratio of the transmitral inflow velocities (E/A),and the deceleration time of the E wave.Results There were 28 patients with E/A ≥ 1.0 (70 ± 12) years old and 73 with E/A ＜ 1.0 (73 ± 10) years old.No patients showed pulmonary congestion on chest radiography.There were no significant differences in age,TTE parameters,and plasma levels of brain natriuretic peptide between the two groups.Patients with E/A≥ 1.0 had higher incidence of left atrial appendage (LAA)thrombus formation and/or spontaneous echograhic contrast than those with ＜ 1.0 (25.0％ vs 5.5％,x2 =7.95,P ＜0.01).A significant relationship was found between E/A and emptying flow velocity of the LAA (r =-0.569,P ＜0.01).Multivariate logistic regression analysis showed E/A was an independent predictor for LAA thrombus (risk ratio 1.531 per0.1 increase,95％ confidence interval 1.129-2.076,P =0.0002).Conclusions Increased level of E/A on admission was associated with the occurrence of left atrial appendage thrombus formation in patients with acute ischemic stroke.

AIM:To observe the expression of connective tissue growth factor(CTGF)in unilateral ureteral obstruction(UUO)rats,and to explore its pathogenic role in renal tubulointerstitial fibrosis.METHODS:48 Wistar rats were randomly divided into sham-operated and UUO group.The rats were sacrificed at day 1,3,7,and 14.The degree of tubulointerstitial damage was scored according to the Masson staining.The mRNA and protein levels of CTGF,transforming growth factor-?1(TGF-?1),collagen Ⅰ(Col Ⅰ),and plasminogen activator inhibitor-1(PAI-1)were detected by reverse transcriptional-polymerase chain reaction(RT-PCR)and immunohistochemistry,respectively.Expression of CTGF protein in the kidney was also assessed using Western blotting.RESULTS:TGF-?1 mRNA level began to increase as early as 1 day after UUO.This increase was followed by the elevation of CTGF mRNA level,which began to increase at third days after UUO(P
