· AlM:To compare the therapeutic effects of different surgical methods in treating pterygium patients and to observe tear film stability.
· METHODS: A total of 120 pterygium patients ( 120 eyes) were divided into three groups, each 40 cases (40 eyes).Data including SchirmerⅠtest (SⅠt), tear break-up time ( BUT) , corneal fluorescein staining ( CFS) were recorded preoperatively and postoperatively to evaluate the clinical efficacy of surgery and the effects of tear function changes.
·RESULTS:There were no significant differences in BUT in group A before the operation and one month after operation.Groups B and C showed significant difference before and after operation, but differences were not statistically significant ( all P<0.05 ); One month after operation, there was significant difference in CFS among group A, B and C (P<0.05), but the difference was not satistically significant between groups B and C; After 3mo, BUT in group A was not significant difference compared with the preoperative; but there was significant difference in groups B and C (P<0.05).When
compared it between groups B and C, there showed no significant difference; Group A showed no significant difference in SⅠt compared with preoperative, SⅠt of groups B and C were significant differences compared with preoperative (P<0.05), but no significant difference between the two groups;After 3mo, CFS of preoperative group A and group B and group C had no significant difference. After 10mo follow - up, there was axsignificant difference ( P<0.05 ) in recurrence rate in group A comparing with groups B and C, there were differences between groups B and C, but no statistically significant.Surgery is more likely to relapse in summer than in winter.
·CONCLUSlON: Pterygium excision combined with self-corneal limbal stem cell transplantation and Tenon capsule closed is an ideal surgical to reduce the recurrence and improve tear film function to some extent.

RhoA, a small GTPase, is involved in a wide array of cellular functions in the central nervous system, such as cell motility, cytoskeleton rearrangement, transcriptional regulation, phagocytosis and cell growth. It is not known how spinal cord injury (SCI) affects the expression of RhoA in different nerve cells. In the present study, we investigated the changes of RhoA expression in remote areas of the injury at the 3rd, 7th and 30th day after SCI, which was established by T10 contusion method. Moreover, we examine its expression profile in neurons, astrocytes and microglia. RhoA was found to be weakly expressed in these nerve cells in normal spinal cord. Western blotting showed that, after SCI, the total RhoA expression was up-regulated, and the RhoA expression was increased and peaked at the 7th day. Double immunostaining revealed specific and temporal expression patterns of RhoA in different nerve cells. The expression of RhoA in neurons started to increase at day 3, peaked at day 7 and then decreased slightly at day 30. Expression of RhoA in astrocytes increased moderately after SCI and peaked at day 7. There was no obvious change in RhoA expression in microglia after SCI in remote areas. This study demonstrated that, after SCI, RhoA expression exhibited different patterns with different nerve cells of spinal cord. RhoA expression patterns also changed with time after SCI, and among different nerve cells in the injured spinal cord. These findings can help us better understand the roles of RhoA in SCI.

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.

Objective To observe the efficacy of the treatment of mycophenolate mofetil (MMF) combined with prednisone on steroid-resistant idiopathic membranoproliferative glomerulonephrifis (IMPGN) patients with moderate to severe proteinufia. Methods Thirteen cases were diagnosed as IMPGN by renal biopsy after excluding secondary factors. Among 13 patients, 9 had severe proteinuria and another 4 had moderate proteinuria, 9 with hypertension and 11 with decreased renal function. Before MMF therapy, all of the cases were resistant to the treatment of glucocorticoid (prednisone 1 mg·kg-1·d-1) for 8 weeks or more. The dose of MMF was 1.5 g/d. Patients were followed up every month for blood pressure, urinary protein excretion, liver and kidney function, complete blood count, and adverse effects. Results At the initiation, the 24 h urinary protein excretion was (4.1±1.4) g, Scr (131.0±44.9) μmol/L, and estimated glomerular filtration rate (eGFR) (63.3±26.8) ml·min-1·(1.73 m2)-1. After prednisene therapy for at least 2 months, the 24 h urinary protein excretion (4.2±1.5) g, Ser (133.2±52.8)μmol/L and eGYR (63.3±27.1) ml·min-1·(1.73 m2)-1did not change significantly. After 3 months of the addition of MMF, 24 h urinary protein excretion declined slightly [(3.8±1.2) g, P>0.05]. After 6 months, 24 h urinary protein excretion declined significantly [(2.5±0.9) g, P<0.05], with decrease in Set and eGFR[(97.2±27.3) μmol/L and (81.3±24.2) ml·min-1·(1.73 m2)-1, P<0.05)]. At the end of 1 year, 24 h urinary protein excretion was only (1.5±0.6) g(P<0.01 ), Ser and eGFR were (95.9±22.5)μmol/L and (81.2±23.8) ml·min-1·(1.73 m2)-1(P<0.01). All the patients experienced a partial remission of proteinuria (urinary protein excretion decreased by 50% or more). Adverse event including stomach upset was found in 1 patient. Conclusion MMF combined with glucosteroids can effectively decrease proteinuria and improve renal function without obvious side effect in steroid-resistant IMPGN.

Objective To study the efficacy of low-dose daytime ambulatory peritoneal dialysis (DAPD) and low-dose CAPD in diabetic end-stage renal disease (ESRD) patients with better residual renal function (RRF). Methods Forty stable diabetic ESRD patients with better RRF (rGFR ≥ 5 ml/min and urine volume ≥ 750 ml/d) were enrolled. They were randomly divided into two groups: low-dose DAPD group (n=20) and low-dose CAPD group (n=20). DAPD group received three 1.5 L to 2 L daily exchanges with a nocturnal empty belly, dwelling for 3 to 4 hours. CAPD group received three 1.5 L to 2 L daily exchange or four 1.5 L daily exchange regimens and dwelled during the night. At the beginning of the study and 6 months later, total weekly Kt/V and Ccr (peritoneal+renal), rGFR were calculated. Meanwhile 24-hour urinary protein,serum albumin (Alb), hemoglobin (Hb), fasting plasma glucose, glycosylated hemoglobin and insulin dosage were measured. Nutritional status was assessed by SGA. Results Thirty-five patients fulfilled the study. There were no significant differences between two groups in age, gender, BMI,PD time, D/Pcr, etc. At the end of the 6th month, the insulin dose[(33.6±10.9) U/d] and 24-hour dialysate protein [(11.13t4.95) g] in CAPD group were significantly higher as compared to DAPD group [(20.6±6.2) U/d, P<0.05 and (5.66±2.88) g, P<0.01 respectively]. Alb in CAPD group [(29.7±4.2) g/L] was significantly lower than that in DAPD group [(36.5 ±3.9) g/L, P<0.05].While the net ultrafiltration [(554±187) ml vs (309±177) ml], 24-hour urine volume [(1090±361)ml vs (750±258) ml] and rGFR [(8.21±2.40) ml/min vs (4.88±2.11) ml/min] in DAPD group were all significantly higher than those in CAPD group (all P<0.05). Conclusion For the diabetic ESRD patients with better RRF, the low-dose DAPD regimen is more effective to control plasma glucose, improve nutritional status and protect RRF than the low-dose CAPD.
