Objective To evaluate the clinical significance of orthotopic continent detenial sigmoid neobladder.Methods 12 patients with bladder cancer were admitted and underwent radical cystectomy and detenial sigmoid neobladder.Results All the 12 patients were followed up for a mean of 18.6 months(range from 6 to 29 months).The blood Cr and BUN levels were both in the normal range without acidosis in all the cases.Only 1 had unilateral ureteral urine reflux during cystography.Of the 12 patients,11 cases(91.7%) achieved continence during daytime;2 cases(16.7%)were incontinent at night,but 1 case could control uri- nation by being woken up at night.The capacity of the neobladder was 220 to 550ml with a mean of 350ml and the maximal pressure of the neobladder during filling was 15 to 55cm H_2O(1cm H_2O=0.098kPa)with a mean of 35cm H_2O.Conclusion As a simple operation the detenial sigmoid neobladder can be performed easily with less complications and more reliable results.This operation may be generally applied in clinical practice.

Objective:To evaluate the anti-tumor immune responses of nureplicable recombinant vaccinia virus-based vaccine expressing HPV16 L1 and L2E7 proteins.Methods:The anti-tumor effects of the vaccine were observed using mouse models of prophylactic,therapeutic and tumor excision.The cell-mediated immunity induced by the vaccine was assessed by enzyme-linked immunospot (ELISPOT) and cytotoxic T lymphocyte (CTL) assay.Results:The vaccine could protect 60% and 50% mice from the challenge of HPV16-positive tumor cells in prophylactic and therapeutic mouse model,respectively.It could protect from recurrence of the tumor in 70% mice of the excision model.The differences among the groups were significant.Strongly specific cell-mediated immunity was found using ELISPOT and CTL assay.Conclusion:The ideal anti-tumor immune responses can be induced by NTVJL1/L2E7 vaccine in mice and it can be considered to be one candidate vaccine of cervical cancer.

Objective To investigate the streptomycin(SM)-resistance of Mycobacterium tuberculosis (MTB) in urine and to examine their relationships with the mutation of rspL gene. Methods 47 strains of MTB were isolated from the urine of patients with renal tuberculosis.The mutation of rspL gene were analyzed by PCR-SSCP with silver-staining,and the strains were tested for the sensitivity to streptomycin. Results All the 47 strains had positive expression of rspL gene of MTB,with 28 SM-resistant and 19 SM-sensitive.Among the 28 SM-resistence strains 19(68%) had rspL gene mutation by SSCP testing.The 19 strains of SM-sensitive had no mutation. Conclusions Detecting mutation of MTB rspL gene in urine by PCR-SSCP can rapidly and exactly identify the MTB's sensitivity to streptomycin,which is significantly important in clinical treatment of anti-tuberculosis.

Objective To quickly pinpoint and correct errors in the application level in No.1 Military Medical Project. Methods LogMiner, a powerful tool provided by Oracle was used to mine and analyze the redo log files produced by oracle database in No.1 Military Medical Project. The basic concept, configuration and usage of LogMiner were described through an example of the Register Program in No.1 Military Medical Project. Results The errors made by Register Program was quickly pinpointed and then corrected by SQL statements provided by UNDO_VALUE field. Conclusion The method using LogMiner to pinpoint and correct the errors in the application level in No.1 Military Medical Project is simple, accurate and convenient. It should be a basic technique for maintenance personnel of hospital information system.

Object To study the chemical constituents of Schizonepeta tenuifolia (Benth.) Briq.. Methods The monoterpenoid constituents of S. tenuifolia were separated on silica gel column and their structures were elucidated by spectral. Results Two new compounds and three known compounds were obtained. Conclusion The new compounds were identified as 3-hydroxy-4(8)-ene-p-menthane-3(9)-lactone and 1, 2-dihydroxy-8(9)-ene-p-menthane.

Tetrahydrobiopterin (BH4) is an essential cofactor for all three nitric oxide synthase (NOS isoforms), which plays an important role in vascular diseases. GTP cyclohydrolase 1 (GCH 1) is the first-step and rate-limiting enzyme for BH4 biosynthesis in its de novo pathway. Common GCH1 gene variant C+243T in the 3'-untranslated region predicts NO excretion. The present study examined the predictive role of GCH 1 gene 3'-UTR C+243T variant in the long-term outcome of ischemic stroke. A total of 142 patients with first-onset ischemic stroke were recruited and detected for genotype of GCH1 3'-UTR C+243T by a TaqMan SNP Genotyping assay. Subsequent vascular events and death were determined over a 5-year follow-up period. The frequency of GCH1 3'-UTR +243 C/T or T/T genotype was significantly increased in patients with endpoint events as compared with those without events (74% vs 57.8%, P=0.06). Cox regression survival analysis indicated that an increased probability of death or new vascular events was found in patients with GCH1 3'-UTR +243 C/T or T/T genotype compared with those with GCH1 3'-UTR C/C genotype (40.6% vs 25.5%), GCH1 3'-UTR +243 C/T or T/T genotype relative to GCH1 3'-UTR C/C genotype was associated with the increased risk of death or vascular events even after adjustment for other risk factors (OR=2.171, 95% CI: 1.066-4.424, P=0.033). It was concluded that GCH1 3'-UTR C+243T variant was an independent predictor of worsening long-term outcomes in patients with first-onset ischemic stroke.

Objective To study the expression of KISS-1 in normal endometrium and in ectopic endometri-um patients with endometriosis. Methods The expression of KISS-1 in 55 cases of normal endometrium as well in 46 cases of ectopie endometriurn with endometriosis were detected by immunohistochemicai EliVision plus method. Results The positive expression rates of KISS-1 in ectopic endometriotic tissues and in normal endometri-urn were 30.43 % and 63.64 % respectively ,and the positive expression rates in ectopic endometriotic tissues signifi-cantly lower than those in the normal endometrium( P< 0.01, P < 0.05). Conclusion The decreased expression of KISS-1 may be related to the mechanism of endometriosis.

Objective To explore the preparation of liposomal clodronate and investigate its inducing effects on the apoptosis of peritoneal macrophages in rats after severe acute pancreatitis (SAP).Methods Liposomal clodronate was prepared by means of thin film. SAP rat model was established by retrograde injection of 5% sodium taurocholate into the pancreatic duct. The peritoneal macrophages were obtained from SAP rats. After exposure to different doses of liposomal clodronate (50, 100,150 μl), the PM proliferation was determined by MTT colourimetry. The apoptosis of PM was measured by flow cytometry and agarose gel electrophoresis, respectively. Results The prepared liposomal clodronate had a suitable encapsulation efficiency of clodronate (5.8%) with an average size of 200 nm. The spherical shape of liposome was confirmed by transmission electron microscope. Exposed to liposomal clodronate of different doses resulted in a obvious growth depression (P＜0.01). The apoptotic rate of the PM was (10.32±0.34) %, (18.16±0.49)% and (29.87±0.35)% in three different dose groups and the difference was marked (P＜0.01). 1.2% of agarose gel electrophoresis of DNA extracted from apoptotic macrophages induced by liposomal clodronate showed clearer and characteristic ladder following the liposomal clodronate concentration. Conclusion Liposomal clodronate has a definite effect on peritoneal macrophages in SAP rats.
