Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

Objective To evaluate the value of using a linear stapler device for the cloure of the pharynx during total laryngectomy.Methods Sixteen total laryngectomies were performed between August 2010 and December 2011,during the operation,the TA 60 linear stapler was used for pharyngeal closure.Among these patients,two patients had the history of pre-operative radiotherapy,four patients recurred after radiotherapy,ten patients were treated for the first time.100 ml methylene blue was injected into the newly closed laryngopharyngeal cavity through the nasopharyngeal breather pipe for checking up whether it was watertight or not.Results Amnong the sixteen patients,methylene blue leakage from the mucosal joint of the gular cavity closed by the stapler were not found in fifteen patients,it was only found in one patient.The transudatory places were sutured with absorbable Vicryl sutures. This patient healed well without pharyngocutaneous fistula.Negative surgical margins were achieved in all patients.No patient needed to be tranfered to open surgery.Using a linear stapler device in total laryngectomy,45 minutes could be saved as compaired to manual suture. One patient developed a light pharyngocutaneous fistula.The incidence of pharyngocutaneous fistula was 6.25% (1/16). Conclusions This stapled closed technique for pharyngoplasty is efficient,eliminates the risk of wound contamination,saves operation time and decreases the incidence of pharyngocutaneous fistula.This technique can be recommended as alternative for repairing the pharynx in patients undergoing total laryngectomy.

Objective: To evaluate the clinical efficacy of the Governor Vessel-unblocking and mind-regulating acupuncture method plus repetitive transcranial magnetic stimulation (rTMS) in the treatment of post-stroke insomnia. Methods: A total of 72 patients with post-stroke insomnia were randomly divided into 2 groups, with 36 cases in each group. The control group received rTMS treatment with a frequency of 1 Hz and a motion threshold value of 90%. The observation group received acupuncture with Governor Vessel-unblocking and mind-regulating method based on the rTMS treatment of the control group. The points were Baihui (GV 20), Shenting (GV 24), Yintang (GV 29), Fengfu (GV 16), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6), Shenmai (BL 62) and Zhaohai (KI 6). The treatment was performed once a day for 5 d a week followed by 2 d of rest for 4 weeks. The improvements of Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were observed after treatment, and the clinical efficacy was compared between the two groups. Results: After 4 weeks of treatment, the PSQI, SAS, and SDS scores of the two groups were all reduced, and the intra-group differences were statistically significant (all P<0.001). After treatment, the three scores in the observation group were all lower than those in the control group, and the differences between the two groups were statistically significant (P<0.05, P<0.05, P<0.001). There was a statistically significant difference between the observation group and the control group comparing the clinical efficacy (P<0.05). Conclusion: The therapeutic effect of the Governor Vessel-unblocking and mind-regulating acupuncture method plus rTMS in treating post-stroke insomnia is better than rTMS alone, and it can better improve the anxiety and depression of patients.

OBJECTIVETo investigate the relationship between the resuscitation promoting role of resuscitation promoting factor and the initial bacteria amount of dormant Mycobacterium tuberculosis.
METHODSMycobacterium tuberculosis (dormant bacteria) was cultured for 100 days, then diluted into 1 mg/ml concentration with 7H9, and further diluted into 0.5, 0.25, 0.125, 0.0625, and 0.03125 mg/ml. Twelve new tubes added with 5 ml 7H9 and divided into two groups: the first group was added with the resuscitation-promoting factor protein, and the second group as control was added with 7H9. In each group the above diluted solutions were added. The tubes were located at 37 degrees C for culture. Optical density (OD) was detected on day 15, 25, 30, and 35. From each tube 1 microl culture solution was plated on 7H11 medium for colony counting.
RESULTSOD detection showed that bacteria proliferation in each group had positive linear correlation (P < 0.05, P < 0.01), indicating that the resuscitation-promoting factor played a similiar role in solutions with different dilution concentrations. 7H11 results and the OD results show that these two detection methods in each group had linear correlation (P < 0.05, P < 0.01), indicating that these two methods showed consistent test results.
CONCLUSIONThe resuscitation-promoting factor has no effect on the resuscitation of dormant Mycobacterium tuberculosis and its initial bacteria amount.

OBJECTIVETo evaluate the application of nephron-sparing surgery (NSS) in the treatment of renal cell carcinoma (RCC).
METHODSThe clinical data of 221 RCC patients who received nephron-sparing surgery were retrospectively reviewed. Open surgery was performed for 203 cases and laparoscopic surgery for 18 cases. The renal arteries were blocked and ice fragments were used for 115 patients. Biopsy was performed on renal tissue adjacent the tumor for 136 patients. After operation 156 patients were treated with interferon and interleukin II. Among these 221 patients, 132 patients (59.7%) were followed for 3-56 months (mean: 28 months).
RESULTSThe mean distance from the edge of normal tissue to the tumor was 0.4 cm (0.2-1.0 cm). The mean volume of blood loss was 180 ml (50-1 000 ml). Pathological examination showed clear cell carcinoma (n = 195), chromophobe renal carcinoma (n = 12), papillary renal carcinoma (n = 7), cystic renal carcinoma (n = 6), and sarcomatoid clear cell carcinoma (n = 1). Biopsies in 136 patients showed negative results. Post-operative complications included leakage of urine (n = 1), hemorrhage or hematuria (n = 5), and infarction of blood vessel of lower limbs (n = 2). During the follow-up, no patients died for this reason, although tumor recurrence (n = 4, 1.8%) and metastasis (n = 3, 1.4%) were noted.
CONCLUSIONNSS is a safe and effective method to treat carefully selected RCC patients.
