OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.

METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.

RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).

CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.

OBJECTIVETo explore the detection rate of myocardial bridge (MB) in coronary angiography and its clinical significance.

METHODThe clinical data of 2 165 cases who had received selective coronary angiography were studied retrospectively.

RESULTSMB was detected in 66 patients (3. 0% ) , among whom 62 were found in left anterior descending artery. Among the 58 cases with isolated myocardial bridge, 24 had no remarkable symptoms, whereas 34 showed clinical symptoms such as angina. The arterial stenosis beneath MB was significantly correlated with clinical symptoms (P < 0. 05 ).

CONCLUSIONThe improvement of the detection rate of MB can effectively decrease misdiagnosis and benefit the treatment.

Objective To examine whether androgen deprivation therapy (ADT) is associated with increased risk of diabetes in men with prostate cancer (Pca).Methods The study data were systematically searched from Medline,Embase,and Cochrane Library Central Register.Studies comparing ADT vs control aimed at treating Pca,reporting diabetes as outcome were included.Results Eight studies met inclusion criteria with a total of 65 695 ADT users and 91 893 non-ADT users investigating the relationship between ADT and diabetes.The incidence of diabetes was 39％ higher in ADT groups,and significant association was observed in overall analysis [RR =1.39,95％CI(1.27-1.53),P ＜ 0.01].In subgroup-analyses stratified by ADT types,diabetes was found to be significantly associated with gonadotropin-releasing hormone (GnRH) alone [RR =1.45,95％CI(1.36-1.54),P ＜ 0.01),GnRH plus oral anti-androgen (AA) [RR =1.40,95％CI(1.01-1.93),P ＜ 0.01] and Orchiectomy [RR =1.34,95％CI(1.20-1.50),P ＜ 0.01],but not with AA alone [RR =1.33,95％CI(0.75-2.36),P =0.33].Conclusions ADT,especially GnRH alone,GnRH plus AA and orchiectomy can increase the incidence of diabetes in patients with Pca.

Objective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.

OBJECTIVETo study the roles of macrophage apoptosis, IL-1, and IL-8 in the pathogenesis of rat pulmonary fibrosis induced by silica.

METHODSForty eight male Wistar rats were divided into the 4 control groups (24 rats) and 4 experimental groups (24 rats). Rats in the control groups were treated with 1 ml normal saline by trachea instillation, whereas the rats in experimental groups were exposed 1 ml silica suspension (100 mg/ml) by trachea instillation for 1, 7, 14 and 28 days, respectively. Six rats of each group were sacrificed, then the bronchoalveolar lavage fluid and lung tissues were collected, respectively. Pulmonary inflammation, fibrosis and other pathological changes were detected with H.E. staining. Morphological changes of the early stage apoptosis in macrophages were detected with transmission electron microscope (TEM). The early apoptosis rates of macrophages in BALF were also assessed using Annexin V-FITC/PI kit. The IL-1 and IL-8 levels of serum were measured with the ELISA.

RESULTSThe apoptotic rates (11.48% +/- 0.24%, 16.03% +/- 0.68%, 15.53% +/- 1.07%, 18.92% +/- 2.70%, respectively) of macrophage in the experimental groups increased obviously with time, as compared to the controls (5.47% +/- 2.06%, 6.39% +/- 0.215, 9.07% +/- 0.61% and 8.54% +/- 0.16%, Respectively) (P < 0.05). The IL-1 levels of serum in the experimental groups were 23.64 +/- 0.84, 23.38 +/- 1.10, 22.21 +/- 0.86 and 24.29 +/- 1.31 pg/ml, respectively, which were significantly higher than those (18.52 +/- 1.23, 18.40 +/- 1.6, 17.92 +/- 2.21 and 18.53 +/- 2.64 pg/ml, respectively) in the control groups (P < 0.05) without time-effect relationship. The serum IL-8 levels on the 1st, 7th and 14th days in the experimental groups were 21.32 +/- 1.44, 21.90 +/- 2.08 and 22.00 +/- 2.80 pg/ml, respectively, which were significantly higher than those (17.69 +/- 1.09, 16.98 +/- 2.09 and 17.54 +/- 1.62 pg/ml, respectively) in the control groups (P < 0.05).

CONCLUSIONThe early macrophage apoptosis and changes of IL-1 and IL-8 may in lungs may play an important role in the development of pulmonary fibrosis induced by silica.

Searching for new antidiabetic lead compound, 4-(1-aryl-3-oxo-5-phenylpentylamino) benzenesulfonamides were designed and synthesized directly by three component one-pot condensation of 4-phenyl-2-butanone and sulfanilamide with some aromatic aldehydes at an yield of 23%-97%. The chemical structures of the twelve new Mannich bases were confirmed by 1H NMR, 13C NMR, FTIR, ESI-MS and HR-MS. The screening results of antidiabetic activity indicated that most of these title compounds possess alpha-glucosidase inhibitory activity, among which compound le is the strongest one. And compound 11 possesses good peroxisome proliferator-activated receptor response element (PPRE) agonist activity. The structure-activity relationship of these new beta-amino ketones containing benzenesulfonamide unit was also discussed preliminarily.

OBJECTIVEObserving the long-term results of reconstructed urethra to reduce the postop infection rate of hypospadias. To explore the standard of selecting tissue for urethra reconstruction by comparing the different inherent liability to infection in use of different kinds of tissue for urethra reconstruction.

METHODSNeo-urethra inner wall and normal urethra were observed through urography and urethroscope. The tissue section of neo-urethra, normal urethra and tissue for urethra reconstruction were observed through light microscope, scanning electron microscope and transmission electron microscope.

RESULTSThe structure and liability to infection of neo-urethra made of bladder mucosa, buccal mucosa or skin never changed after long time. Metaplasia never took place in neo-urethra.

CONCLUSIONSThe structure and liability to infection of neo-urethra were the same as those of the congeneric tissue. Bladder or buccal mucosa is the best tissue for urethra reconstruction considering urethra microenvironment. Neo-urethra made of skin is more liable to infection by nature. The best opportunity of hypospadias operation should be before puberty.

OBJECTIVEThis clinical study was to explore why the neo-urethra is liable to be infected after hypospadias operation, find the source and the common floras of infection, and accordingly, improve the peroperation procedures so as to reduce postoperative infection rate.

METHODSThe pathogenic floras were examined and analyzed by germiculture and karyotype analysis.

RESULTSThe bacteria in the neo-urethra mostly came from the orifice and the reconstruction material of the urethra. The most common floras that caused infection were gram-positive coccus. The most sensitive antibiotics for hypospadias infection were demethylvancomycin.

CONCLUSIONThe postoperative infection of hypospadias is incisional, not the urinary system infection. Because the microenvironment of the neo-urethra is more suitable for infection than that of the skin or mucosa, the reconstructed urethra is likely to be infected.
