The 80 eyes of A group were treated by conventional phacoemulsification; the patients (60 eyes) of B group were given huoxuehuayu decoction orally for two courses after phacoemulsification. Best-corrected visual acuity(BCVA), corneal and aqueous conditions ,thickness of macular central fovea and changes of macular retinal tissue in A, B groups were observed before surgery, 1 day; 1 week,2,4,6,8 weeks and 3 months after surgery. Was significantly higher than that of group A. One week after surgery the ratio of mild aqueous flare in group B was significantly lower than that of group A. The thickness of central fixation was significantly increased in both groups 1 week, 2, 4, 6, 8 weeks and 3 months after phacoemulsification; the difference between 2 to 8 weeks after surgery and pre-operation showed statistical significance in both groups. 11 eyes in A group had macular edema during 2 to 6 weeks after surgery, including 9 eyes with fovea thickened and 2 eyes with cystoid macular edema, and seven eyes' edema disappeared in 3 months. 2 eyes in B group had macular edema, including 1 eye fovea thickened and 1 eye cystoid macular edema, during 4 to 6 weeks after surgery, and the two eyes' edema disappeared 3 months after surgery. The fovea thickness in group B during 2 to 8 weeks after surgery was statistically lower than group A. Phacoemulsification.

OBJECTIVETo evaluate the value of high mobility group box 1(HMGB1) in the diagnosis of pediatric acute appendicitis.

METHODSThe children with acute abdomen who had a diagnosis of suspected acute appendicitis between January and July 2013 and 25 healthy children were enrolled in this study. Serum HMGB1 levels were measured using ELISA on admission. The patients were classified into 2 groups according to surgery confirmation or pathological results: appendicitis (n=28) and non-appendicitis (n=35).

RESULTSSerum HMGB1 levels and WBC in the appendicitis and non-appendicitis groups were significantly higher than in the healthy children group (P<0.01). The appendicitis group showed more increased serum HMGB1 levels compared with the non-appendicitis group (median: 32.9 ng/mL vs 22.0 ng/mL; P<0.01). For a diagnosis of acute appendicitis, the sensitivity and specificity of serum HMGB1 was 71.4% and 82.9% respectively at the best cutoff of 28.0 ng/mL, with the accuracy of 77.8% and the area under the curve of 0.765 (95%CI 0.638-0.893).

CONCLUSIONSHMGB1 may play a role in the diagnosis of pediatric acute appendicitis.

AIMTo study the relativity of the renocortical lipid peroxidation with renal tubules structure damage in renal injury induced by cisplatin in rats.

METHODSFemale Wistar rats were randomly divided into NS group, CDDP(I) group, CDDP(II) group and CDDP(III) group. All rats were injected via the tail vein with NS or cisplatin and NS qd in five days. The changes in content of Scr, BUN and MDA, the activity of SOD and GSH-Px of the renal cortex were measured. Alkaline phosphatase of renal tubular epithelia was stained by histochemistry and the slices of renal cortex were observed.

RESULTSThe contents of Scr and BUN of CDDP groups were significantly higher than those of NS group (P < 0.01). The content of renocortical MDA was significantly higher than that of NS group (P < 0.05). The activities of renoconical SOD and GSH-Px were lower than those of NS group (P < 0.05). The content of MDA, activities of renocortical SOD and GSH-Px with the content of Scr and BUN were significantly correlative. Alkaline phosphatase of renal tubular epithelia cells was losed largely and renal tubular epithelia cells were denaturative and necrotic partly in sections.

CONCLUSIONThe damage of renal cortex was correlative with its lipid peroxidation. The injury of renal cortex became heavier with cisplatin dose increased.

Background Macular edema following phacoemulsification with intraocular lens (IOL) implantation is a main factor to influent visual function.The administration of traditional medicine can relieve tissue edema,but its preventive and treatment efficacy on macular edema after phacoemulsification with IOL implantation remaines unclear.Objective This study was to investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification with IOL implantation.Methods A case-controlled observational study was designed.One hundred and eighty eyes of 150 patients with age-related cataract were randomized into operation group and operation + medicine group.Phacoemulsification with IOL implantation was performed in both groups,but huoxuehuayu decoction was orally administered for 14 days in operation+medicine group.The best corrected visual acuity,inflammatory reaction of the ocular anterior segment,and macular edema were recorded before operation and 1 week,2,4,6,8 and 12 weeks,and the central macular thickness was measured using optical coherence tomography.Results Twelve weeks after surgery,the ratio of visual acuity ≥ 1.0 was in significantly higher in operation+medition group than that of in operation group (x2 =1.066,P＞0.05).One week after surgery,the eyes of the aqueous flare were much nore in the operation group than that of operation+medicine group(x2 =9.341,P＜0.05).The thickness of the central fovea was significantly increased in both groups at 1 week,2,4,6,8 and 12 weeks after surgery,showing significant differences in comparison with preoperation (operation group:P ＜ 0.01 ; operation + medicine group:P ＜0.05).Macular edema occurred in 13 eyes in operation group during the following-up duration,including 11 eyes with thickened fovea and 2 eyes with cystoid macular edema.Maeular edema disappeared in 10 eyes 12 weeks later.In the operation+medition group,3 eyes happened macular edema,including thickened fovea in 2 eye and cystoid macular edema in 1 eye.Four to six weeks after surgery,macular edema disappeared in 3 eyes 12 weeks later.The fovea thickness in the operation+medicine group was statistically significantly lower from 2 through 8 weeks after surgery than that in the operation group(t=2.315,2.323,3.104,2.470,P＜0.05).Conclusions Oral administration of huoxuehuayu decoction is helpful for the restoration of the anterior ocular segment.Huoxuehuayu decoction can protect macula from the edema induced by phacoemulsification.

OBJECTIVE Diabetic nephropathy (DN) has been one of the most common complications of diabetes and the leading cause of end-stage renal disease. Glomerular hyperfiltrationis central in earlystage of DN and leads to the progression of renal architectonic and functional abnormalities. Salvi?anolic acid A (SalA) has been proved to protect diabetic complications such as hepatic fibrosis and neuropathy. The present study was designed to investigate the effects of SalAon glomerular endothelial dysfunctionand diabetic nephropathy. METHODS Primary glomerular endothelial cells were subjected to assess permeability under injury of advanced glycation end-products (AGEs). AGEs-induced changes of RhoA/ROCK pathway and cytoskeleton rearrangement were assessed bywestern blotandimmunoflu?orescence. The beneficial effects of SalA on diabetic nephropathy were investigated in a rat model induced by high-fat and high-glucose diet combined with low dose of streptozocin (35 mg·kg- 1, ip). Renal function and architectonic changes were evaluated by biochemical assay and PAS staining. RESULTS SalA 3μMameliorated AGEs- induced glomerular endothelial permeability (P<0.05) and suppressed rearrangement of cytoskeleton through inhibiting AGE-RAGE-RhoA/ROCK pathway. SalA 1 mg · kg- 1 markedly reduced endothelium loss (P<0.01) and glomerular hyperfiltration (P<0.05) in diabetic kidney. Subsequently,SalA 1 mg·kg-1 suppressed glomerular hypertrophy and mesangial matrix expansion, eventually reduced 24 h-urinary albumin and ameliorated renal function by decreasing blood urine nitrogen (BUN), serum creatinine (Scr) and serum n-acetyl-β-d-glucosaminidase (NAG). AGEs-RAGE-Nox4-induced oxidative stress was suppressed by the treatment of SalA 1 mg·kg-1. CONCLUSION SalA ameliorated AGEs-induced glomerular endothelial hyperpermeability, and effec?tively protected against early-stage diabetic nephropathy by reducing hyperfiltration and alleviating renal structural deterioration through inhibiting AGEs and its downstream pathway. Thus, SalA might be a promising therapeutic agent for the treatment of diabetic nephropathy.

Coronary artery disease (CAD) remains a leading cause of morbidity and mortality in the world. Although the comprehensive control of cardiovascular disease risk factors has achieved remarkable progress in recent years, the incidence of cardiovascular events is still high after the control of traditional risk factors such as low density lipoprotein cholesterol, blood pressure and blood glucose, collectively referred to as cardiovascular residual risk. Inflammation is a central driver of atherosclerosis and the ultimate rupture of plaque, as well as an important cause of residual cardiovascular risk. Therefore, this article reviews the formation, assessment and treatment of residual inflammatory cardiovascular risk.

Objective To evaluate the protective efficacy of influenza vaccine in the elderly in China. Methods The Chinese databases (CNKI, Wan Fang, VIP) and English databases (Pubmed, Embase) were searched, then studies related to the protective efficacy of influenza vaccine in the elderly according to pre-designed criteria were included and the vaccine efficacy(VE) was selected as an evaluation index. Rev Man 5.3 and Stata 12.0 were used in this meta analysis. Results A total of 26 studies (2000-2016) including 6 kinds of outcomes were eligible, of which, 22 articles related to influenza like illness (ILI) , 5 articles related to common cold (CC) , 11 articles related to the attendance rate due to ILI and CC, 7 articles about chronic diseases (including Hypertension, Diabetes, Coronary Heart Disease (CHD) , Stroke, Cancer, Chronic bronchitis and others) , 6 articles about chronic disease treatment and 3 articles about all-cause mortality. The VE of influenza vaccine was 58.00% (95%CI: 48.00%-66.00%), 40.00%(95% CI: 30.00%-50.00%), 42.00% (95% CI: 34.00%-49.00%), 17.00% (95% CI: 11.00%-23.00%), 28.00%(95% CI: 14 .00 % -40.00 %) and 28 .00 % (95% CI: 15 .00 % -39 .00 %) , respectively. Conclusion Influenza vaccination can effectively prevent the occurrence of influenza like disease and other symptoms in the elderly in China.

The aim of this study is to investigate the effects of the metformin on the formation of hepatic fibrosis in type 2 diabetic rats and discuss its mechanism of liver-protecting activity. After SD rats were fed with high-fat and high-sucrose diet for four weeks, low-dose streptozotocin (STZ) was injected intraperitoneally to make the animal mode of type 2 diabetes. Then, all diabetic rats was fed with the high-fat diet and metformin (ig, 100 mg x kg(-1)) was given orally to metformin group for four months. After the last administration, fasting blood glucose was determined. The livers were removed to calculate the hepatic coefficient and to make HE and Picro acid-Sirius red staining, immunohistochemistry (alpha-SMA and TGFbeta1) and TUNEL staining in order to evaluate the effect of metformin on the hepatic fibrosis. The animal model of type 2 diabetes with hepatic fibrosis was successfully made. Metformin can significantly alleviate the lesions of hepatic steatosis and fibrosis, markedly reduce the expressions of alpha-SMA and TGFbeta1 in liver tissue of type 2 diabetic rats. However, TUNEL staining result suggested that metformin could not reduce apoptosis of hepatocytes. The results suggest that metformin can inhibit the formation of hepatic fibrosis in type 2 diabetes.

OBJECTIVETo investigate the effects of valsartan on expression of angiotensin II receptors in different regions of heart after myocardial infarction (MI).

METHODSCanines were divided into sham-operated control group (n=7), infarction group (n=7) and Valsartan group (10 mg x kg(-1) x day(-1) for 4 weeks after MI operation, n=7). Four weeks after operation, Doppler tissue imaging (DTI) was used to evaluate regional ventricular function in the noninfarcted myocardium (apical and basal near to the infarction region). The mRNA and protein expressions of angiotensin II type 1 receptor (AT1-R) and angiotensin II type 2 receptor (AT2-R) on the corresponding regions were detected by competitive reverse-transcriptase polymerase chain reaction technique and immunohistochemical technique respectively. Results The protein and mRNA expressions of AT1-R were significantly increased in both apical and basal regions near to the infarction in dogs with MI compared with those in control group (P < 0.05) which could be downregulated by valsartan (P < 0.05). AT2-R expressions were significantly upregulated in infarction group in both apical and basal regions compared with those in control group and valsartan further increased AT2-R expressions in both areas (P < 0.05). Myocardial peak systolic velocity (Sm), myocardial peak early diastolic velocity (Em) and myocardial peak late diastolic velocity (Am) at both apical and basal regions near to the infarction regions were significantly lower in MI group than those in the control group which could be significantly improved by valsartan.

CONCLUSIONBoth mRNA and protein expressions of AT1-R and AT2-R are upregulated in noninfarcted regions near MI, valsartan improved myocardial function via inhibiting AT1-R upregulation and enhancing AT2-R upregulation.
