?AIM:To evaluate the clinical outcomes of Nd:YAG laser capsulotomy in the treatment of early stage capsular block syndrome ( CBS) .?METHODS:Eighteen patients (21 eyes) with early stage capsular block syndrome were treated using Nd:YAG laser by anterior capsulotomy only or combined with posterior capsulotomy from January 2010 to July 2015 in Anyang Eye Hospital. Uncorrected distance visual acuity, intraocular pressure, spherical equivalent, depth of anterior chamber were observed preoperatively and 2wk postoperatively.?RESULTS:Seventeen eyes simply underwent peripheral anterior capsulotomy with Nd:YAG laser. Four eyes were combined with posterior capsulotomy. Compared with preoperative, uncorrected distance visual acuity improved, intraocular pressure returned to normal, degree of myopia reduced, depth of anterior chamber had deepened.? CONCLUSION: Nd: YAG laser capsulotomy is an effective treatment for early stage capsular block syndrome.

Objective To investigate the situation of prevalence,treatment and control of hypertension in patients with chronic kidney disease(CKD)by CROSS-sectional study. Methods Nine hundred out-patients with CKD in our department from November 2006 to March 2007 were enrolled in the study,including 480 male and 420 female.Among 900 CKD cases,354 patients underwent maintenance dialysis,including 228 on hemodialysis and 126 on peritoneal dialysis.Results The prevalence of hypertension in CKD patients was 80.2%(nude 83.5%vs female 76.4%,P<0.01).The prevalence of hypertension in patients on dialysis was significantly higher than that in non-dialysis patients(90.1%vs 73.8%,P<0.01),but there was no significant difference between hemodialysis and peritoneal dialysis cases.Antihypertensive treatment rate was 92.4%in CKD patients with hypertension.and was significantly higher in patients on dialysis than that in non-dialysis patients(95.6%vs 89.8%.P<0.01).The control rate according to current recommendations for CKD patients (BP<130/80 mm Hg) was very low. Control of both SBP and DBP was only achieved in 20.4% of non- dialysis patients. The control rate of hypertension (BP< 125/75 mm Hg) in patients with proteinuria >1 g/24 h was 8.4%. The proportion of dialysis patients with BP<140/90 mm Hg was significantly lower than that of non-dialysis patients (45.2% vs 55.5%, P<0.01). The percentage of hemodialysis patients with BP < 140/90 mm Hg was significantly higher than that of peritoneal dialysis patients (49.8% vs 36.5%, P<0.05). The prevalence of hypertension was associated with the decrease of renal function and the increase of age. The prevalence of hypertension in diabetic nephropathy was higher than that in primary glomerular diseases. Patients received 1, 2, 3 and 4 or more kinds of antihypertensive drugs accounted for 37.2%, 37.5%, 19.3% and 5.9% respectively. The combination of calcium channel blocker (CCB) and renin-angiotensin-aldosterone system (RAAS) inhibitors was more frequently used in CKD patients. The CCB was the most frequently prescribed drug (74.1% ), followed by angiotensin Ⅱ receptor blockers (ARB) (48.4%), angiotensin-converting enzyme inhibitors (ACEI) (25.6%) and alpha, beta-blockers (24.7%). Conclusions The prevalence of hypertension in CKD patients is quite high, which is associated with the progression of renal function, increase of age, the type of underlying kidney disease, obesity and diabetes mellitus. The control of hypertension is unsatisfied in CKD patients, especially in dialysis patients and those with overt proteinuria.

ObjectiveTo compare the efficacy and safety of intermittent patient-initiated single-dose antibiotic prophylaxis and continuous antibiotic prophylaxis for the prevention of recurrent urinary tract infection (UTI) in postmenopausal women. MethodsA randomized controlled clinical trial was conducted for the prevention of recurrent urinary tract infection. Single dose of antibiotic was given every night in continuous antibiotic prophylaxis group and every time after exposure to conditions predisposed to UTI in intermittent antibiotic prophylaxis group. The duration of prevention was 12 months in both groups. ResultsThe effective rates of intermittent antibiotic prophylaxis and continuous antibiotic prophylaxis were 71.0% and 81.8% respectively (P＞0.05). The incidence of gastrointestinal adverse reaction in intermittent antibiotic prophylaxis group was significantly lower than that in continuous antibiotic prophylaxis group (7.7% vs 28.6%,P＜0.05). ConclusionsCompared with continuous antibiotic prophylaxis, intermittent patient-initiated single-dose antibiotic prophylaxis is a better prophylaxis with less gastrointestinal adverse reactions for the prevention of recurrent urinary tract infection in postmenopausal women.

Different factors including hybridization solution components, hybridization temperature, and the concentration and proportion of the labelled primer, which affected the sensitivity and specificity of single mutation identification, were exploited. Asymmetric PCR increased the hybridization sensitivity, and the asymmetric multi-PCR did not affect the specificity, while the sensitivity was improved a little. Among 30 lung cancer samples detected with the oligonucleotide microarray, 12 was found P53 gene mutations and 5 had K-ras gene mutations. The P53 gene mutations identified by the oligonucleotide microarray was proved 80% same as the sequencing results. The obvious statistical relations of K-ras and P53 gene mutations with tumor type, tumor stage and smoking were not obtained because of less samples and mutation sites.

Objective To clarify the relationship between clinical manifestation and pathological features of IgA nephropathy (IgAN) patients with mild proteinuria and/or hematuria.Methods Clinicopathological data from 316 biopsy-proven IgAN cases (proteinuria＜1 g/24 h and/or hematuria, and Scr＜133 μmol/L) from our hospital between January 1993 and October 2009 were studied retrospectively. The renal histopathology was quantified according to Lee's grading and Katafuchi's semi-quantitative standard, and the risk factors for renal pathological lesions were evaluated using multifactor logistic regression analysis. Results Among these 316 patients, 123 were male and 193 patients were female. The mean age at the time of renal biopsy was (33.10±10.69) years old. Clinical features were found as follows: hematuria with proteinuria was found in 267 patients (84.5%), isolated hematuria in 24 patients (7.6%), and isolated proteinuria in 25 patients (7.9%). 16.5% of patients had hypertension. The percentages of CKD stage Ⅰ, Ⅱ, Ⅲ were 76.9%, 20.9% and 2.2%, respectively. 31.3% of patients presented Lee's grade Ⅲ or more severe.52.8% of patients had various degrees of glomerulosclerosis. Crescent formation was observed in 20.3% of patients. 22.5% of patients showed tubular atrophy;16.8% showed interstitial fibrosis and 24.7% also had renal vascular lesions. The extent of glomerulosclerosis was negatively correlated with eGFR levels, but positively correlated with the amount of proteinuria and mean arterial pressure (MAP) level (P＜0.05). The score of tubulointerstitial lesion was positively correlated with the amount of proteinuria and negatively correlated with eGFR and hemoglobin (Hb)level (P＜0.05). The degree of renal vascular lesion was also correlated to MAP level positively and eGFR level negatively (P＜0.05). Multifactor logistic regression analysis revealed that proteinuria, Scr and Hb at the time of renal biopsy were independent risk factors for severe renal pathological lesions (Lee's grade Ⅲ or more severe) with odds ratio of 8.564, 1.031 and 0.975 respectively (all P＜0.01). Conclusions Severe renal histological lesions and decrease of renal function may be seen in some IgAN patients with mild proteinuria and/or hematuria. The levels of proteinuria,Scr and Hb are the independent risk factors for severe renal pathological lesions. Renal biopsy is important in these patients in order to make diagnosis and individual treatment.
