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.

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 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.

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.

OBJECTIVETo evaluate the safety and effectiveness of endourological techniques in the treatment of benign prostate hyperplasia (BPH) in aged high-risk patients.

METHODSWe used endourological techniques in the treatment of 283 BPH patients aged over 70 years and complicated with hydronephrosis, renal failure, heart failure, cerebral infarction, respiratory dysfunction, anemia, diabetes, bladder tumor, or prostate weight over 80 g, TURP (transurethral resection of the prostate) for 112 cases and PKRP (transurethral plasmakinetic resection of the prostate) for the other 171. All the patients were followed up for 1-30 months.

RESULTSIn the TURP group, the scores on IPSS and QOL were decreased from 27.5 +/- 2.8, 5.5 +/- 1.0 to 5.8 +/- 1.2, 1.0 +/- 0.5, and the residual urine volume (RUV) from (75.0 +/- 20.0) ml to (8.0 +/- 3.0) ml, but the maximal flow rate (Qmax) increased from (6.5 +/- 2.0) ml/s to (18.5 +/- 1.5) ml/s (P < 0.05), while in the PKRP group, the scores on IPSS and QOL were decreased from 28.2 +/- 2.2, 5.5 +/- 1.0 to 5.4 +/- 1.6, 1.0 +/- 0.5, and RUV from (80.0 +/- 20.0) ml to (7.0 +/- 3.0) ml, and Qmax increased from (6.8 +/- 2.1) ml/s to (20.0 +/- 1.5) ml/s (P < 0.05). There were no statistically significant differences in IPSS, QOL, Qmax and RUV after treatment between the two groups (P > 0.05), but significantly less complications were found in the PKRP than in the TURP group (P < 0.05).

CONCLUSIONEndourological treatment, especially PKRP, with comprehensive perioperative preparations, unerring operative skills, well-controlled operation time, and intensive postoperative monitoring and nursing, has the advantages of high safety, less bleeding, fewer complications and definite effectiveness for aged high-risk BPH patients.

OBJECTIVETo search for a new method for urethra reconstruction using autologous buccal mucosal graft while lacking of local skin.

METHODSSince 1998, a total of 25 patients with complex hypospadias have been treated using buccal mucosal grafts for urethral reconstruction. The reconstructed urethra was anastomosed with the meatus half year later.

RESULTSAll the reconstructed urethra survived without contracture or stricture except one infection, which healed with no adverse consequence.

CONCLUSIONThe key points for operation success is rich capillary network, thick epidermis and thin lamina propria of the buccal mucosa. Buccal mucosa is an excellent tissue for urethral reconstruction.
