Objective To investigate the therapeutic effects of orthotopic urinary diversion in women. Methods From September 1995 to December 2003,34 female patients (mean age,58 years;range,53-64 years) with bladder cancer were included.Of them,30 cases were of primary tumors and 4,of recurrent ones.Pathology showed transitional cell carcinoma in 30 cases,bladder adenocarcinoma in 3 and squamous cell carcinoma in 1.Radical cystectomy was performed in all the 34 cases;and the technique of cystectomy with nerve-sparing was performed in 24 of them. Intraoperative frozen section of the distal urethra surgical margin showed no evidence of tumor,and ileal neobladder was formed in all.The clinical therapeutic effects were analyzed retrospectively. Results The mean operative time was 360 min(range,280-420 min),and mean blood transfusion was 600 ml(range,300-1000 ml).Thirty cases were followed up for a mean of 61 months(range,6-108 months).At 6 months after surgery the continence rate was 90%(27/30) during the day and 86%(26/30) at night.Twenty-three cases could empty the neobladder one time and 2 needed intermittent catheterization due to hyper-continence; the other 5 needed pushing the abdomen to empty the neobladder. Twenty-three patients had good urodynamic findings;the vesical capacity ranged 300-520 ml and maximum intravesical pressure were

0.05).The operation was failed in 2 cases due to the displacement of the renal tube(re-puncture was performed) or massive hemorrhage from torn renal calices(the procedure was terminated,and the bleeding was controlled by compression and hemostat).One patient developed acute pulmonary edema after the operation and was cured by diuretic;4 cases showed postoperative fever;no serious complications occurred in this series.The stone-free rate in one session was 89.1%(49/55).The residual calculi were all cleared by a second operation combined with extracorporeal shock-wave lithotripsy.The patients were followed up for 3 to 12 months(mean,6 months),during which no recurrent case was found.ConclusionUreteroscopy is safe and effective for establishing renal channel in minimally invasive percutaneous nephrolithotomy.

Objective To investigate the construction and implementation of the concept of precise sequential therapy for primary liver cancer.Methods The clinical data of 207 patients with resectable liver cancer who were admitted to the Air Force General Hospital from May 2005 to June 2010 were retrospectively analyzed.Of all the patients,81 received conventional therapy (conventional therapy group),and the other 126 patients received precise sequential therapy (precise sequential therapy group).The conditions of the patients in perioperative phase,during postoperative sequential treatment and the period of follow-up between the 2 groups were compared.All data were analyzed by using the covariance analysis,analysis of variance,chi-square test or rank sum test.Results The detection rates of lesions with a diameter less than 1 cm,operation time,liver resection volume,intraoperative blood loss,rate of perioperative blood transfusion,duration of postoperative hospital stay,incidences of postoperative complications were 81％ (22/27),( 186 ± 36) minutes,(75 ± 29) ml,( 189 ± 60) ml,24％(30/126),(21 ± 12)days and 13％ (17/126) in the precise sequential therapy group,and 18％ (2/11),(222 ± 30)minutes,(133 ±88)ml,(327 ±46)ml,51％ (41/81),(26 ± 17)days and 20％ (16/81) in the conventional therapy group,respectively,with significant differences between the 2 groups (F =10.876,7.390,46.996,31.025,14.556,6.315,4.017,P ＜ 0.05).No significant difference was observed on the levels of alanine transaminase,albumin and the Child-Pugh score before and after the intervention in the precise sequential therapy group,but significant differences were observed in the conventional therapy group.The 1-,2-,3-year tumor recurrence rates and the 1-,2-,3-year survival rates were 17％ (21/126),22％ (17/76),26％ (8/31) and 87％ (110/126),87％ (66/76),84％ (26/31) in the precise sequential therapy group,and 31％ (25/81),38％ (27/71),48％(31/65 ) and 77％ (62/81),75％ (53/71 ) and 60％ (39/65) in the conventional therapy group,respectively.There were significant differences in the prognosis of the patients in the 2 groups ( x2 =4.958,4.292,4.168,4.062,3.640,5.470,P ＜ 0.05 ).Conclusion Through accurate assessment of the patients' condition before surgery,precise hepatectomy and precise postoperative intervention,the goal of effective control of tumor recurrence,maximum protection of the liver function and improvement of the survival rate can be achieved.

Objective: To investigate the cinlical features and therapeutic methods of unex-pected gallbladder carcinoma. Methods: A retrospective analysis was performed in 19 cases of unexpected gallbladder carcinoma treated in our hospital from April 2002 to April 2008. Results: Ten cases in early stage were perfomed gallbaldder resection and local lymph node removal, and the average survival time was 18.7 months; 4 cases were perfomed extend radical resection, and the average survival time was 12.3 months; 5 cases were performed palliative resection, and the survival time was less than 6 months. Conclusions: Frozen section examination during opera-tion is key to diagnose unexpected gallbladder carcinoma. Radical resection is the first option once the diagnosis is confirmed, and the method can be decided according to Nevin classification and B ultrosound scaning during opreation.

OBJECTIVE:To explore the role of clinical pharmacists participating in drug therapy for patients with severe infec-tions. METHODS:Clinical pharmacists participated in drug treatment for a patient with tropical candidemia and assisted physicians to adjust anti-infective treatment plan. According to the results of blood culture,clinical pharmacists suggested Piperacillin sodium and tazobactam sodium for injection 3.75 g,ivgtt,q8 h+Caspofungin acetate for injection 50 mg (initial dose of 70 mg),ivgtt, qd,for symptomatic treatment;increased the daily dose of Caspofungin acetate for injection to 50 mg,ivgtt,bid due to plasma ex-change;Caspofungin acetate for injection 50 mg,ivgtt,qd+Amphotericin B for injection 0.1 mg/kg,ivgtt,qd for anti-infective plan due to the possible“contradiction”of echinocandins;closely monitored ADR,such as allergy,erythra,renal function injury. RE-SULTS:Physicians adopted the suggestions of clinical pharmacists,vital sign of patient kept stable,and tropical candidemia was not detected in the blood culture;the patient was transferred to general ward for further treatment. CONCLUSIONS:Based on the results of blood calture,clinical symptoms and the characteristics of drug effects,clinical pharmacists participated in the treatment for the patient with severe infection,retrieved related treatment guideline,assisted physicians to adjust anti-infective plan and close-ly monitored possible ADR so as to guarantee the effectiveness and safety of anti-infective treatment.

This histochemical binding of horseradish peroxidase labeled peanut agglutinin (HRP?PNA) to paraffin sections of 18 cases of pancreatic cancer was investigated with 5 case of normal pancreas and 8 pancreatitis as the control. The PAN receptor was not found in the normal pancreas, but it appeared in 15 cases of pancreatic cancer (82%). Three cases of pancreatitis presented positive stainings of PNA binding (37%). There were 3 kinds of PNA binding forms: (1) linear distribution along the gland of carcinoma cells; (2) round staining with the ductal epithelium; and (3) diffuse scattering with an increased dot staining. There was a good relationship between the staining degree and cell differentiation. The positive staining increased when the cell was transformed from inflammation to carcinogenesis, and decreased from well differentiation to poorly differentiation.

Aim To investigate the vasodilatory effect and the mechanisms of urocortin(Ucn) on the thoracic aorta of spontaneously hypertensive rats(SHR).Methods Rings cut from SHR thoracic aorta were used in vitro.The endothelium dependent and independent vasorelaxing effects of Ucn were measured.Furthermore,it was also explored whether the relaxing effects of Ucn were affected by N~((?)) nitro-L-arginine methyl ester(L-NAME), methylene blue(MB) and glybenclamide.Results Ucn(1 nmol?L~(-1)～1 ?mol?L~(-1)) caused concentration dependent relaxation in SHR thoracic aorta with endothelium and without endothelium(P

Objective To observe the protective effect of total flavonoids from hawthorn leaf on ligation-induced acute myocardial ischemia in anesthetized dogs. Methods The coronary arteries of anesthetized dogs were ligated to induce the model of acute myocardial ischemia. The indexes including the changes of ST segment in electrocardiogram (∑-ST and N-ST) and the release of LDH and CK were measured after treatment. Meanwhile,the size of myocardial ischemia was observed by TTC staining method. Result Total flavonoids from hawthorn leaf depressed the increase of ∑-ST and N-ST,decreased the release of LDH and CK,and reduced the myocardial ischemic size. Conclusion Total flavonoids from hawthorn leaf has an effect on relieving myocardial ischemia.

0.05).Conclusion: The method of constructing a highly invasive subline of bladder neoplasm is reliable,and EGFP transfection does not change the biological behavior of the cells.The obtained sublines may provide a valuable experimental platform for further study on the molecular mechanisms of bladder neoplasm metastasis.

Objective To investigate the molecular mechanism of the effect of CYP2C19 polymorphism on the efficacy of clopidogrel in patients with stable coronary artery disease (SCAD).Methods A total of 208 patients with coronary artery disease undergoing percutaneous coronary intervention (PCI) were included.The CYP2C19 variant alleles were detected by gene sequencing.Platelet reactivity was assessed by thrombelastograph at 24 h after 300 mg clopidogrel loading.P2Y12-Gi signaling was measured by flow cytometric analysis of vasodilator-stimulated phosphorylation-platelet reactivity index (VASP-PRI) and Akt phosphorylation (P-Akt) index.Results Among 208 patients,40.9％ were classified as CYP2C19 * 1/* 1 (non-carriers) with no loss-of-function (LOF),44.7％ as CYP2C19 * 1/* 2 or CYP2C19 * 1/* 3 (one LOF carriers) and 14.4％ as CYP2C19 * 2/*2 or CYP2C19 * 2/* 3 (two LOF carriers).Both postclopidogrel platelet aggregation and VASP-PRI increased by the presence of one LOF allele,and were even more pronounced with the presence of two LOF alleles.In contrast,P-Akt index only increased in two LOF carriers.VASP-PRI was positively associated with postclopidogrel platelet aggregation (r =0.661,P＜0.001),but not with P-Akt index.Conclusions The two CYP2C19 LOF carriage was associated with more active state of P2Y12-Gi signaling in postclopidogrel platelet in Chinese patients with SCAD.
