Objective To observe the effectiveness of probucol for non-proliferative diabetic retinopathy (NPDR) with hyperlipidemia.Methods Fifty-two patients (104 eyes) of NPDR with hyperlipidemia were enrolled in this study.The patients were randomly divided into treatment group and control group,26 patients (52 eyes) in each group.Both groups received diet and exercise guidance,oral hypoglycemic agents and (or) intensive insulin therapy.After blood sugar and blood pressure were controlled,the treatment group received probucol 0.5 g,two times per day; and the control group received atorvastatin of 10 mg,one time per day.The total course was 12 months.Before and after one,three,six and 12 months,all patients underwent vision,ophthalmoscope,fundus fluorescein angiography,blood and urine tested.Variations of visual acuity,fundus condition,macular edema,triglyceride (TG),total cholesterol (TC),low-density lipoprotein cholesterol (LDLC),high-density lipoprotein cholesterol (HDLC) and 8-0HdG were observed before and after treatment.Results The total effective rate of visual prognosis were 44.23％ and 40.38％ in the treatment group and the control group,the difference had no statistical significacy (Z＝-0.335,P＞0.05).Retinal hemorrhages and microaneurysms alleviated after treatment in both groups.The total efficiency of fundus prognosis was 65.38％ in the treatment group and 36.54％ in the control group,and the difference was statistically significant (Z=-2.973,P＜0.05).Macular edema was in six and five eyes in the treatment group and the control group respectively,which were lower than before treatment,the difference was statisticaly significant (x2=4.833,4.300; P＜0.05).Between the two groups,the difference was not statistically significant (x2 =0.102,P＞ 0.05).Twelve months after treatment,TG,TC and LDLC were decreased in the treatment group (t=15.653,7.634,14.871) and control group (t=13.275,7.415,13.632),and the difference was statistically significant (P＜0.05).HDLC showed no significant difference than before in the two groups (t=0.584,0.275; P＞0.05).TG,TC,LDLC and HDLC showed no difference between the two groups (t＝1.857,0.133,1.671,0.875; P＞0.05).8-0HdG decreased gradually during the one,three,six and 12 months in the treatment group (t=7.352,15.581,27.324,28.143) and control group (t =6.877,8.672,14.671,14.855) after treatment,and the difference was statistically significant (P＜0.05).In the first month aftertreatment,8 0HdG showed no difference between the two groups (t=0.513,P＞0.05).In the 3,6,and 12 months after treatment,the 8 0HdG was lower in the treatment group than that in the control group,and the difference was statistically significant (t =3.434,5.917,5.226; P＜0.05).Conclusion In the treatment of NPDR with hyperlipidemia,probucol can reduce blood lipid,stable visual function and relieve macular edema.

Objective To investigate the timing of cholecystectomy in patients with mild biliary acute pancreatitis.Methods 80 patients with mild acute biliary pancreatitis were prospectively collected.According to the principle of random digital table, the patients were randomly divided into the study group and control group,40 cases in each group.The study group underwent early cholecystectomy, while the control group received delayed cholecystectomy.Main indicators included biliary tract complications, perioperative complications, conversion to open surgery, operation time and total hospital stay were observed.Results Compared with the control group, the total hospitalization time of the study group was significantly shorter[(9.39±2.48)d vs.(11.48±3.28)d,t=3.582,P=0.000].There were no statistically significant differences in the rate of conversion to open surgery, operation time, perioperative complications and mortality between the two groups (P>0.05).The incidence rates of acute cholecystitis, biliary colic and total biliary complications of the study group were 0.00%,0.00% and 0.00%, which were significantly lower than those in the control group (15.00%,22.50% and 47.50%) (x2=4.505,8.013 and 22.364,P=0.034,0.005 and 0.000).Conclusion Early laparoscopic cholecystectomy is helpful to reduce the incidence of adverse events in the biliary system.

The preclinical safety assessment of hepatotoxicity drugs has a low sensitivity and low specificity. Related tests often generate false negative results and unexpected toxicity,which is one of the major reasons for the cessation of development and withdrawal from the market. Proteomics enjoys advantages of rapidness,high sensitivity and high throughout,and therefore can be used in the search for new biomarkers of hepatotoxicity in preclinical studies,leading to the development of safer drugs and a more efficient drug discovery process. In this review,the current preclinical biomark?ers of liver toxicity and development of proteomic technologies in the discovery and validation of bio?markers of drug-induced liver injury are described,in general the application of proteomics to Chinese medicine-induced liver toxicity in particular. Compared with traditional methods,proteomic technologies show promising results for the discovery of novel hepatotoxic markers. Proteomics,in conjugation with other omics techniques,will play a major role in the early stage of hepatotoxicity screening and will prove to be a good bridge in clinics in the future.

Spontaneous rhythmic activity of pacemaker neurons in the central nervous system underlies fundamental neurological processes such as locomotion, cognition and circadian rhythm. Among the wide range of ion channels required for its generation, the Ca2+-activated K+(KCa) channels play a prominent role in maintaining physiologically-relevant frequency and pattern of pacemaker activity. Much of our understanding of the functions of KCa channels in pacemaker neurons have been derived from pharmacological studies using channel modulators, such as iberiotoxin and apamin. Despite the significant advances made, recent studies have painted an increasingly complex picture of the effects of widely used KCa channel modulators on unintended targets that may confound our under?standing of their functions. In this review, we discussed the utility and shortcomings of the KCa channel modulators, and highlighted the significance of these findings, because the KCa channel modulators have been used in early clinical trials to treat disorders ranging from Parkinson disease to alcoholism.

Objective To investigate the correlation between plasma fibronectin (Fn) level and the hemorrhagic transformation (HT) in patients with acute ischemic stroke.Methods Patients with acute ischemic stroke,symptom onset within 72 hours,no bleeding at baseline MRI (including gradient echo sequences) and without thrombolytic therapy were recruited prospectively.At 7 - 10 days after symptom onset reexamined MRI.The patients were divided into HT and non-HT groups according to whether they had a hemorrhage or not.The plasma Fn levels in both groups were compared.Logistic regression analysis was used to investigate the predictors of HT.Results A total of 78 patients were included,and among them 11 patients (14.10％ ) showed HT.The proportions of atrial fibrillation (36.4％ vs.9.0％,P =0.012) and cardioembolism (36.4％ vs.6.0％,P =0.021) in the HT group were significantly higher than those in the non-HT group.The baseline mean systolic blood pressure (182.09 ±20.73 mm Hg [ 1 mm Hg=0.133 kPa]vs.161.25 ±26.40)mm Hg,P =0.015),mean diastolic blood pressure (98.00 ± 11.26 mm Hg vs.86.60 ± 15.21 rnm Hg,P =0.020),and plasma Fn level (4 835.04 ± 756.30 μg/L vs.3 849.44 ± 1 289.18 μg/L,P =0.016) were all significantly higher than those in the non-HT group.Multivariate logistic regression analysis showed that plasma Fn level (odds ratio [ OR],1.001,95％ confidence interval [ CI] 1.000 - 1.001,P =0.017) and atrial fibrillation (OR,13.408,95％ CI 1.963 -91.592,P =0.008) were the independent predictors of HT in patients with acute ischemic stroke.Conclusions The plasma Fn level in patients with HT increased significantly.The plasma Fn level can be used as an independent predictor of non-thrombolytic HT after the onset of acute ischemic stroke.

ObjectiveTo explore the clinical effects of laparoscopic common bile duct exploration and primary suture combined with choledochoscopy (LBEPS) and laparoscopic common bile and duct exploration T-tube drainage(LCHTD) on cholelithiasis.Methods101 cholelithiasis patients were selected and,grouped by the operation methods.56 cases were treated with LCHTD,while 45 cases were treated with LBEPS.The operation time,blood lose,and postoperative digest function recovery time were ampared betreen two groups.ResultsThe operation time betreen the two groups has no significant difference(P ＞ 0.05 ),while the blood lose,postoperative digest function recovery time in LBEPS group were better than the LCHTD group( all P ＜ 0.05 ),the differences were statistically significant.Meanwhile the LBEPS group had a less complication and re-treatment rate than those of the LCHTD group ( P＜0.05).ConclusionCompared with LCHTD,LBEPS had smaller trauma,less operation complications and faster postoperative digest recovery time,worthy of clinical promotion.

ObjectiveTo observe the effect of probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis.MethodsEighty-six patients with stenosis carotid atherosclerosis were separated into two groups with 43 cases each by random digits table.The patients were treated with probucol combined with atorvastatin in observation group and atorvastatin only in control group.The changes of arteriosclerotic plaque and blood fat pre- and poet-treatment were observed.Results There was no significant difference in the levels of lumen area (LN) and intima-media thickness (IMT) pre-treatment between two groups (P＞ 0.05).Compared with pre-treatment,the levels of LN and IMT post-treatment were significantly decreased in observation group(P ＜ 0.05 ),while no significant difference in control group (P ＞0.05).There was significant difference in the levels of LN and IMT post-treatment between two groups [(0.59 ±0.19) cm2 vs.(0.72 ±0.28) cm2,(2.76 ±0.41 ) mm vs.(3.27 ±0.57) mm](P＜ 0.05).There was no significant difference in the levels of total cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) pre-treatment between two groups (P ＞0.05).Compared with pre-treatment,the levels of TC,TG,LDL-C post-treatment were decreased,HDL-C was increased,there were significant differences (P ＜ 0.05 ).Post-treatment,the levels of TC,TG,LDL-C in observation group were lower and HDL-C was higher than those in control group (P ＜ 0.05).Conclusion Probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis can improve arteriosclerotic plaque and low blood fat,which can be applied in clinic.
