Objective To evaluate the treatment and p re vention of urethral stricture complicated by transurethral vapo-resection of pr ostate (TVP). Methods Retrospective analysis was conduct ed by reviewing medical records and following up the patients under study.Among 3012 patients with benign prostatic hyperplasia treated with TVP, urethral stric ture occurred 4 weeks to 22 months following surgery in 95 cases (3.15 %), inclu ding anterior in 47 (49.5%),posterior in 31 (32.6 %) and bladder neck contractur e or occlusion in 17 (17.9%).Their mean age was 68.7 years (range, 55 to 85 year s). Results The 95 patients were followed up for 4~36 m o nths (mean,14 months).Of them,65 cases underwent conventional dilation, in them 59 (90.8%) were cured and 6 had failure,then turning to internal urethrotomy;19 cases underwent internal urethrotomy plus dilation,in them,13 (68.4%) were cured and 6 had failure,then turning to urethroplasty;17 cases of bladder neck contra cture or occlusion underwent transurethral resection of bladder neck scar tissue ,with a cure rate of 88.2% (15 were cured and 2 experienced failure). Conclusions Urethral stricture is a common complication after TVP. The key points of managing the strictures are patients’ alert,close follow-up and early effective treatment.

Objective To investigate the dynamic changes of endothelial progenitor cells (EPCs) in peripheral blood of patients with hypertensive cerebral hemorrhage.Methods Flow cytometry was used to detect the dynamic changes of EPCs in 79 cases of hypertensive cerebral hemorrhages as the experimental group and 70 cases of normal healthy people as the control group.Results In the acute phase after hemorrhage (3 days),EPCs in experimental group [(51.3 ±9.3) × 103/ml,(52.0 ±6.3) × 103/ml,(53.1 ±9.3) × 103/ml] were significantly lower than the control group [(75.4 ± 15.6) × 103/ml] (P <0.05).However,after that the level of EPCs in experimental group [(110.9 ± 12.0) × 103/ml,(132.8 ± 11.8)× 103/ml,(115.3 ±9.9) × 103/ml] increased rapidly and was significantly higher than the control group (P <0.05),and approximately two weeks later it reduced to normal levels [(83.1 ±7.9) × 103/ml].Conclusions In patients with hypertensive cerebral hemorrhage,the levels of EPCs in peripheral blood were closely related with the disease and might become a prognostic marker.

PET and PET/CT are the methods of displaying the functional and metabolic changes in tissues. With its high sensitivity and specificity, it can be used as a noninvasive systemic functional examination. There are significant values in its diagnosing, staging, treatment directing and prognosis assessing in the malignant lymphoma.

Objective To compare the efficiency of compressive bandage dressing and drainage on the blood loss after total knee arthroplasty (TKA). Methods Patients (n=120) who visited Tianjin General Hospital Bin Hai Branch and Tianjin People's Hospital due to varus knee osteoarthritis and underwent TKA were retrospectively analyzed.There are 20 males and 100 females with, mean age was 65.18±6.88 years. Depending on whether placement of drainage, patients were divided into drainage group (60 cases) and pressure bandage dressing group (60 cases). Blood loss, blood transfusion and full blood count (FBC) were all analyzed after TKA in both groups. Results Blood loss after TKA in drainage and pressure dressing group were (1 026.85±274.44),(789.52±251.58) mL respectively. Blood loss was less severe in pressure dressing group than that in drainage group (t=4.938, P<0.01). Allogeneic transfusions were needed in 14 cases of drainage group and five cases of pres?sure bandage dressing group. The circumstances that requires blood transfusion was significantly lower in pressure bandage group than that in drainage group (χ2=5.065, P<0.05). The postoperative limb swelling and postoperative joint mobility did not show statistical significance (P>0.05). Conclusion Application of compressive bandage dressing in TKA surgery is easy to be operate and can reduce perioperative blood loss and allogeneic transfusion incidence.

Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50% on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective To evaluate the relationship between the anesthesia factor and myocardial injury in the patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).Methods Eightyeight patients of both sexes,aged 42-71 yr,weighing 59-83 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association Ⅱ or Ⅲ),scheduled for elective coronary artery bypass grafting with CPB,were divided into 4 groups (n =22 each) using a random number table:routine anesthesia control group (group C),dexmedetomidine-based anesthesia group (group D),sevofluranebased anesthesia group (group S) and dexmedetomidine combined with sevoflurane anesthesia group (group DS).After tracheal intubation,0.2%-2.1% sevoflurane was inhaled until the beginning of CPB in S and DS groups.In D and DS groups,dexmedetomidine was intravenously infused as a loading dose of 1 μg/kg over 10 min before induction of anesthesia,followed by an infusion of 0.4 μg · kg-1 · h-1 until the end of surgery.Before induction of anesthesia,before CPB,after the end of CPB,immediately after the end of surgery and at 24 h after surgery,venous blood samples were collected for determination of plasma creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) concentrations by immunofluorescence.The restoration of spontaneous heart beat and adverse events such as hypotension,malignant arrhythmia,cardiac arrest and respiratory depression during surgery and within 24 h after surgery were recorded.Results Compared with group C,the plasma concentrations of CK-MB and cTnI were significantly decreased in the other three groups (P<0.05).The plasma eoncentrations of CK-MB and eTnl were significantly lower in group DS than in S and D groups (P<0.05).There were no significant differences in the rate of restoration of spontaneous heart beat among the four groups (P> 0.05).No adverse events were found during surgery and within 24 h after surgery in the four groups.Conclusion Dexmedetomidine combined with sevoflurane anesthesia is helpful in reducing myocardial injury and provides better efficacy than either alone in the patients undergoing cardiac surgery with CPB and is more suitable for cardiac surgery with CPB.
