Objective To investigate the old patients with vagina inflammation Candida and Trichomonas infection situation,provide the basis for clinical diagnosis and treatment.Methods 6 738 patients with vagina inflammation in the vaginal were retrospectively analyzed.Candida and Trichomonas detection results were compared, and focused on elderly patients with three different age groups (group 55 -65years old,>65 -75years old group and the group >75years)of two kinds of pathogenic microorganism infection status.Results 125 cases of detection in elderly patients with vagina inflammation,accounted for 1 .8%,including detection Candida 37 cases,infection rate was 29.6%;Trichomonas detection 12 cases,infection rate was 9.6%;The dual infection in 2 cases,infection rate was 1.6%.55 -65years old group,>65 -75years old group and >5 -year-old group infection rates were 52.2%(chi-square=6.33),30.4%(chi-square=6.21),10.0%(chi-square=6.13).55 -65years old group of two kinds of pathogenic microorganism infection rates were higher than that of >65 -75 years old group and >75 years old group,>65 -75 years old group is higher than that of >75 -year-old,differences were statistically significant (P<0.05 ).Conclusion In elderly patients with vagina inflammation has certain Candida and Trichomonas infection rate,the main pathogen of bacterial infection of Candida,and younger people has higher infection rate than older peo-ple.

Objective To evaluate the efficacy of treating female conyloma acuminatum with the CO2 laser under colposcopy guidance and traditional Chinese medicine sticking therapy.Methods Female patients with conyloma acuminatum whose diagnosis were confirmed by pathologic examination,were randomly assigned to two groups:a treatment group of 100 cases and a control group of 80 cases,with no statistical differences of the age and the duration.The treatment group was treated by CO2 laser to remove conyloma acuminatum and subclinical damage,and then by TCM wart-washing decoction sticking after operation; The control group was treated by CO2 laser to remove the wart,and then by TCM wart-washing Decotion for fumigating after operation.Results The curative rate of the treatment group and the control group was 79.00％and 60.00％ respectively.There was significant difference between the two groups (x2=7.723,P＜0.01).Conclusion The treatment of CO2 laser under colposcopy guidance combined with Chinese medicine sticking therapy is effective for female conyloma acuminatum.

Problem-based learning(PBL) teaching mode was applied in Urology practice of the medical students.The externs were organized to analyze and discuss a real case,having grasped enough knowledge of relative diseases,and to provide their advice about the diagnosis and treatment,changing question mark into a full stop.And then their conclusions were verified by post-operational follow-up.PBL teaching mode can increase the students'study motivations and interests and the ability to resolve practical problems,master medical knowledge,train their clinical thinking and enhance the quality of teaching and thus it is an effective teaching mode.

Objective To evaluate the efficacy of retroperitoneoscopic radical nephrectomy.Methods From October 2001 to September 2006,a total of 108 patients underwent retroperitoneoscopic radical nephrectomy in our department.The tumors sized 1.0-8.0 cm in diameter with a mean of(4.3?2.9)cm.Before the operation,42 patients were in stage T1N0M0,54 in stage T2M0N0,and 12 in stage T3aN0M0.Results The operation time was 35-180 min with a mean of(63.5?30.3)min,and the blood loss was 20-1500 ml [mean,(75?23)ml].Totally 3 patients were converted to open surgery.The intra-and postoperative complications included hemorrhage caused by the injury of the inferior vena cava or renal artery(4 cases),wound infection(3 cases),and hypercapnia(8 cases).The patients were followed up for 6-36 months(over 12 months in 61 cases),during which 2 patients died of pulmonary metastasis one year after the surgery,1 patent died of liver metastasis 7 months after postoperation,the other 105 patients survived without tumor.The 1-year survival rate was 98.4%(60/61);and 3-year survival rate was 85.7%(18/21).Conclusions Retroperitoneoscopic radical nephrectomy is mini-invasive and effective for renal carcinoma.The patients recover quickly after the surgery.The procedure is worth being wildly used.

Objective: To study the effects of genistein on the proliferation and cell cycle progression of human gastric carcinoma cells. Methods: 3H TdR incorporation test was used to investigate the cell proliferation. Flow cytometry was used to analyze the cell cycle arrest. Immunocytochemistry technique and Western blotting were used to observe the cyclin B and P21 waf1/cip1 protein expression. Results: Genistein inhibited the proliferation of tumor cells significantly, arrested cell cycle progression at G 2/M phase, and enhanced cyclin B and P21 waf1/cip1 protein expression in dose dependent manner. Conclusion:Proliferatory inhibition and G 2/M arrest of human gastric carcinoma cells after treated with genistein may be due to increased stability of cyclin B protein and the expression of P21 waf1/cip1 .

Background and purpose: Primary signet ring cell carcinoma(SRCC) of the bladder is rarely diagnosed in the clinic. Few cases have been reported in the literature, so there was lack of understanding of the primary bladder SRCC in terms of diagnosis and treatment. Our study was to investigate the clinical features and treatment strategy for primary SRCC of the bladder and review the status of the disease along with the literature. Methods: 3 cases of primary bladder SRCC were studied, including clinical features, treatment, follow-up and their prognosis.The literature was reviewed. Results: All cases received ultrasound, computerized tomography, cystoscopy, biopsy and other related lab tests for diagnosis and differential diagnosis. Laparoscopic radical cystectomy and orthotopic ileal neobladders were performed in 2 cases, while the other case received laparoscopic radical cystectomy and ileal conduit diversion, Chemotherapy (cisplatin and 5-fluorouracil) was delivered in one case after surgery. One patient died at 6 months postoperatively because of multiple metastasis. The other 2 cases have been followed-up only for 8 and 12 months postoperatively, and no recurrence or metastasis have been observed. Conclusion: Primary SRCC of the bladder lacks distinctive clinical and imaging manifestations. The tumor grows very invasively. Radical cystcctomy is one of the optimal approaches for treatment of SRCC of bladder.

Background and purpose: The prognostic factors on survival for the patients with prostate carcinoma are still underdeterrnined. This study was to analyze the survival of three common treatment methods for prostate carcinoma and the prognostic factors on survival. Methods: 494 male patients who were diagnosed as prostate cancer were enrolled into the retrospective study. All of the data like age, stage, grade, PSA level, ALP, Hb and treatments were collected. Overall survival and disease specific survival rates for patients were analyzed by Kaplan-Meier method. Prognostic factors on disease specific survival were also analyzed by Log-rank test and Cox proportional hazards model. Results: Disease specific survival rates at 1, 3 and 5 year were 96.0%, 89.0% and 80.0% for all 494 patients, respectively. Disease specific survival rate at 3-year was 92.4% for brachytherapy, 100.0% for radical prostatectomy and 80.6% for hormonal therapy (P=0.008). Multivariate analysis by Cox model showed that stage, PSA level and age significantly impacted on disease specific survival. Conclusion: Brachytherapy and radical prostatectomy provides longer survival time than hormonal therapy for patients with prostate cancer. Clinical stage and PSA level and age of prostate cancer are independent factors impacting on survival significantly.

Objective To evaluate the clinical efficacy and safety of laparoscopic nephron sparing surgery in the treatment of T1 renal cell carcinoma. Methods Thirty-two patients (24 males and 8 females) were diagnosed with T1 N0 M0 renal cell carcinoma by ultrasound, CT or MRI and un derwent laparoscopic nephron sparing surgery. The mean age was (49±2)years old (from 31 to 72 years old). The mean tumor diameter was (2.8±0.8)cm. There were 21 tumors in left kidney, 11 in right kidney. Of them, 10 tumors were in upper pole, 13 in lower pole, 5 in kidney center, 4 close to renal hilum, 18 in dorsal side and 14 in ventral side of the kidney. Tumor masses were resected with the surgical margin of 0. 5 cm. Twenty-five cases were done through retroperitoneal approach and 7 cases was done through transperitoneal approach. The pathological results showed that there were clear cell renal carcinoma in 28 cases, granule cell renal carcinoma in 3 cases and oncocytoma in 1 case. Renal function was examined by ECT before and after the surgery. Results Thirty-one cases under went laparoscopic nephron sparing surgery successfully and only one case converted to open surgery due to excessive intra-operative bleeding. The mean renal pedicle blocking time was (24±4)min (from 19 to 52 min). There were 3 cases having blocking time longer than 30 min (38 min, 45 min and 52 min) and accepted secondary blockage during the procedure. The mean operative time was (105 ± 15) rain. The mean estimated blood loss was (120±22)ml. Only 6 cases accepted 400 ml blood transfusion. D-J stents were placed in 5 eases with the tumor in kidney center before operation. In 3 cases with intra-operative exposure of renal calyx, D-J stems were placed after operation. Urine leakage in 2 eases were noted at 2 and 3 days and recovered at 15 and 21 days after operation. The mean hospital stay was (9±2)days. There was no recurrence in a mean follow-up time of (23±5)months. There were 3 cases with local hematoma (1 case of 4 cm × 3 cm, 2 cases of 2 cm×3 cm) in the surgical site confirmed by ultrasound or CT scan 1 month after surgery and they disappeared 3 months after the operation. Serum creatinine and urea nitrogen were all in normal range after operation. Compared with renal blood flow of the operated kidney before operation, there were 9 cases decreased by 10 %- 15 and 3 cases decreased by 20% at 15 days, 7 cases decreased by 10%-15% at 1 month and 3 cases decreased by 10%- 15% at (23 ± 5) months after operation. Conclusion Laparoscopic nephron sparing surgery is one of feasible and safe options for the treatment of T1 renal cell carcinoma.

BACKGROUND:It is notable to treat cervical spondylosis using the anterior cervical discectomy and fusion, but there are such complications as cervical instability and low fusion rate. Titanium plate with cage can solve those defects, while anterior unfamiliar matter and dysphagia appear. A new anterior cervical interbody fusionZero-Pwith support and fixation function has been widely used in clinic.
OBJECTIVE:To analyze early stability in repairing cervical spondylosis using a newZero-Pinterbody fixation and fusion system, and compare with a titanium plate with cage interbody fixation andfusion system.
METHODS:We retrospectively analyzed the clinical date of 31 patients with cervical spondylosis who underwent the anterior cervical discectomy and fusion in the Department of Orthopedics, Affiliated Hospital of Jiangsu University between August 2010 and August 2014. Fifteen patients were treated with aZero-P implant (Zero-Pgroup) and sixteen patients with a titanium plate with cage (cage group). We recorded operation time, intraoperative blood loss, preoperative and postoperative Visual Analogue Scale scores and Japanese Orthopedic Association scores, postoperative incidence of dysphagia and degeneration rate of adjacent joint.
RESULTS AND CONCLUSION:(1) Postoperative symptoms were apparently improved, without severe complications in both groups. (2) Operation time and intraoperative blood loss were better in theZero-P group than in the cage group (P< 0.05). (3) Postoperative Visual Analogue Scale scores and Japanese Orthopedic Association scores were significantly improved in both groups (P< 0.05). The recovery rate of Japanese Orthopedic Association scores was similar between the two groups (81%, 81%;P> 0.05). (4) Mild dysphagia was experienced by one case (7%) in theZero-Pgroup, but nine cases (44%) in the cage group. Significant difference in the incidence of dysphagia was detected between the two groups after treatment (P=0.037). However, no significant difference in degeneration rate was detectable between the two groups (P=0.48). (5) These findings verify that in the anteriorcervical discectomy and fusion, the new Zero-Pand titanium plate with cage interbody fixation and fusion system are effective choices for cervical spondylosis. However, theZero-Pinterbody fixation and fusion system showed a low incidence of postoperative dysphagia and better stability.
