Background There is no effective preventing way for the posterior capsular opacification(PCO) after cataract surgery.Objective The aim of this study was to investigate the preventing effect of adenovirus-mediated herpes simplex virus thymidine kinase/ganciclovir(HSV-tk/GCV) system on PCO.Methods Twelve New Zealand white rabbits were divided into BSS+BSS group,BSS+GCV group,HSV-tk+BSS group and HSV-tk+GCV group at random.Phacoemulsification was performed in bilateral eyes of rabbits,and 0.1ml of BSS or adenovirus vector with HSV-tk gene were injected into lens capsular bag during the operation based on the grouping.In 12 hours after operation,0.1ml BSS was injected into the anterior chamber daily for 3 times in BSS+BSS group and HSV-tk+BSS group,and 0.1ml GCV was used in the same way in BSS+GCV group and HSV-tk+GCV group.The situations of the anterior segment and the posterior capsule were examined under the slit lamp postoperatively.All the wet weight of capsular bags was assessed using electronic balance.The capsular membrane was histopathologically examined in the 4th week after injection.PCO was graded according to the method of Couderc.Results Mild corneal edema and aqueous humor opacity were observed in all the eyes within 3 days and returned to normal level gradually within 2 weeks postoperatively.PCO scores were higher in BSS+BSS group,BSS+GCV group,HSV-tk+BSS group than the HSV-tk+GCV group,showing the significant differences between them(H=2.647,P=0.008;H=2.939,P=0.003;H=2.884,P=0.004).No obvious difference was seen in PCO score among BSS+BSS group,BSS+GCV group,HSV-tk+BSS group(P＞0.05).The wet weight of the capsular bags in HSV-tk+GCV group was reduced in comparison with BSS+BSS group,BSS+GCV group,HSV-tk+BSS group with the statistically significant difference between them(q=9.93,q=10.15,q=10.07,P＜0.05).Histopathological examination revealed that mild proliferation of lens epithelial cells(LECs) at the capsular equator and migration toward the posterior capsule to form a thin soemmering ring in the periphery of the capsular bags and thin fibromembrane at the center of the capsular bags without cells or cortices in HSV-tk+GCV group.However,in BSS+BSS group,BSS+GCV group and HSV-tk+BSS group,the proliferation and migration of LECs were more obvious to form a dense soemmering ring in the periphery of the capsular bags and thick fibromembrane in the center of capsular bags.Conclusion Adenovirus-mediated HSV-tk/GCV system can effectively prevent PCO.

Objective To investigate the relationship between metabolic syndrome(MS) and severity of coronary atherosclerosis. Methods Sixty-four hospitalized patients diagnosed as coronary heart disease were divided into MS group(n=26)and non-MS group(n=38).All the patients underwent 16-row multi-slice CT coronary angiography,and cardiovascular risk factors were evaluated. Results The prevalence of MS increased with the number of stenosed coronary arteries(P

OBJECTIVETo explore the genotypes of human papilloma virus (HPV) in male patients with condyloma acuminate in Lishui area of Zhejiang Province, China.

METHODSUsing HybriMax, we identified the genotypes of HPV of the verruca samples from 110 male condyloma acuminate patients aged 16 - 65 years in Lishui area.

RESULTSHPV infection was detected in 107 (97.27%) of the condyloma acuminate patients, including 76 cases (71.02%) of simple infection and 31 cases (28.97%) of multiple infection. The peak age of infection was 21 - 40 years old. Totally, 14 genotypes of HPV were identified, including the high-risk genotypes as HPV16, 53, 52, 33, CP8304, 58, 51, 45, 66, 68, and 59, which accounted for 44.85% of the cases, and the low-risk ones as HPV6, 11, and 19 (43), with an infection rate of 93.45%.

CONCLUSIONThe low-risk genotype is a dominant type of HPV infection and the rates of high-risk genotype and multiple infection are high among the male condyloma acuminate patients in Lishui area.

This study was to investigate the diagnosis value of simplified uredynsmic test in stress urinary incontinence. Fifty patients with stress test-confirmed urine incontinence underwent simplified urodynamic test before routine urodynamic test. Detrusor instability, max bladder volume, average flow rate, and residual urine of simple urodynamic test were compared. Simplified urodynamic test showed a sensitivity of 87%, specificity of 9/12, positive predictive value of 92%, and negative predictive value of 9/14. There was no significant difference in max bladder volume, average flow rate, and residual urine between the two tests. Simplified urodynamic test might be a reliable method for diagnosis of stress urinary incontinence, and could be used for detrnsor instability screening.

Objective To investigate the clinical efficacy and improvement of patients' quality of life in tension-free vaginal tape(TVT)and tension-free vaginal tape obturator(TVT-O)for surgical treatment of severe female stress urinary incontinence.Methods This study was a randomized,singleblinded,controlled trial.Patients were randomized by a computer-generated randomization schedule with allocation to either TVT or TVT-O procedure.TVT procedure was performed in 35 cases and TVT-O in 34 cases.None had received surgery for urinary incontinence or was in pregnancy.Transvaginal hysterectomy and prolapse reparation were done simultaneously in some of the patients.All patients were requested to complete the Urinary Distress Inventory(UDI-6)and Incontinence Impact Questionnaire(ⅡQ-7)as part of their pre-and postoperative assessment.Results All patients were evaluable and the mean follow-up was 14.5 months.The mean operative time was(18±5)min in the TVT-O group,Significantly shorter than in the TVT group(27±5)min(P＜0.01).The two groups did not differ significantly in perioperative blood loss,postoperative complications(including tape erosion,pain in thigh or behind pubis),postvoid residual volume,hospital stays or expenses(all P＞ 0.05).Sixty patients were successfully treated for stress urinary incontinence(88.6%and 85.3%for TVT and TVT-O groups,respectively).There were significant improvements in postoperative scores for both the ⅡQ-7 and the UDI-6(P＜0.01),except in subscale measuring symptoms of voiding dysfunction(P＞0.05).Conclusions Both techniques appear to be equally effective in the surgical treatment of severe stress urinary incontinence in a short term review.Significant improvements could also be seen in patients' quality of life.However.TVT-O has a shorter operative time.No evidence of increasing risk of urethral obstruction after the operation could be found.Long term followups axe necessary to evaluate outcomes of different types of surgery for stress urinary incontinence.

This study is to develop a sensitive method by using reversed-phase high performance liquid chromatography coupled with UV detector (HPLC-UV) to simultaneously determine four bioactive compounds, iriflophenone 3-C-beta-D-glucoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside in the leaves of Aquilaria sinensis. An Agilent Zorbax SB-C, column (4, 6 mm x 250 mm, 5 microm) was used, and the gradient elution was performed with mobile phase of 0.1% aqueous phosphoric acid and acetonitrile at a flow rate of 1 mL x min(-1). The detection wavelength was 280 nm, and the column temperature was 25 degrees C. The four marker compounds were well separated with good linearity (R2 > 0.9990), precision, stability and repeatabili y. The-recovery rates were in the range of 98.80%-101.39%. For 15 branch of the leaves, the contents of iriflophenone 3-C-beta-D-gluoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside were between 0.41-14.48, 0.72-3.85, 4.30-29.07, 0.24-5.06 mg, respectivley. This method is precise, accurate and reliable, which provides an efficient way for the quality control of the leaves of A. sinensis. This will promote the comprehensive usage of this plant.
