Abstract?AIM: To discuss clinical efficacy and safety of 10g/L atropine with short covering for children with amblyopia.?METHODS: Eighty -eight children ( 88 eyes ) with amblyopia, staying in hospital from February 2011 to February 2014 for treatment, were divided into control group ( n =44 ) and observation group ( n =44 ) . The control group only given short covering therapy was observed.Observation group was given 10g/L atropine treatment besides covering.Clinical efficacy, treatment compliance, visual acuity, corrected spherical degree of amblyopia eye and adverse events were observed and compared.?RESULTS:1) After treatment, total effective rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group ( 80%, 35/44, P<0.05 ); 2 ) excellent compliance rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group (82%, 36/44, P<0.05);3) visual acuity of the two groups when the disease was first diagnosed was not significantly different (P>0.05), but increased number of lines of vision and corrected spherical degree of amblyopia eye in the observation group were significantly higher (P<0.05);4) in the observation group total rate of adverse events was 9% ( 4/44 ) , significantly lower than that in the control group (23%, 10/44, P<0.05).?CONCLUSION: The combined therapy, 1% atropine with short covering, is effective and safe for amblyopia in children.

Objective To investigate the inhibitory effect of paclitaxel on rat graft arteriosclero- sis and the mechanism.Methods The rat abdominal aortic allograft model was used.All rats were divided into three groups:isograft control group (Wistar to Wistar),allograft group (Wistar to SD) and allograft paclitaxel-treated group (Wistar to SD).Rats in allograft paclitaxel-treated group re- ceived paclitaxel (2 mg?kg~(-1)?d~(-1)) from the operation day to post-operative day 14 and others received same dosage of vehicle (0.9% normal saline).Animals were sacrificed and the grafts were harvested at 30th day after operation.Intimal proliferation was studied by light microscopy.The apoptosis of vascular smooth muscle cells (VSMCs) was detected by transmission electronic microscopy and termi- nal deoxynucleotidyl transferase biotin nick end-labeling (TUNEL) method.Results Morphological analysis showed that grafts had no change after operation in isograft control group,but in allograft group intimal proliferation,inflammatory cells infiltration in neointima and adventitia and stenosis of allografts were obvious.After treatment with paclitaxel,there was a significant decrease in intimal proliferation,inflammatory cells infiltration and stenosis.Apoptosis index of VSMCs was higher in the allograft paclitaxel-treated group than other groups.Conclusion Paclitaxel can inhibit intimal pro- liferation in aortic allografts and prevent the graft from arteriosclerosis possibly by inducing the apoptosis of VSMCs.

Objective To investigate the influence of thiamine deficiency(TD)at early pre- pathological lesion stage on cognitive function and the correlation between cognitive dysfunction and hippocampal neurogenesis.Methods TD mouse model was prepared by feeding a thiamine-depleted diet. Learning and memory functions of TD mice were tested with Y-maze.Hippoeampal neurogenesis was studied with bromodeoxyuridine(BrdU),proliferative cell nuclear antigen(PCNA),and Doublecortin(Dcx) immunohistochemical staining on the 7th(TD7),9th,14th and TD25th day.Results TD9 mice without pathological impairment and cholinergic nerve degeneration needed more times of training(22.3?2.2)in the learning test of Y maze compared with the controls(13.5?3.5).Correspondingly,the numbers of BrdU-positive ceils and the immunoreactivity of Dcx decreased significantly in the TD9 mice(19.8?0.4, 1537.2?50.2 vs 23.9?0.3,2688.9?127.9 pixels/mm~2).Thiamine re-administration reversed the declined hippocampal neurogenesis:the number of BrdU-positive cells was 23.6?1.9 and Dcx immunoreactivity was 2052.3?269.6 pixels/mm~2:the impaired learning ability was simultaneously restored,with the number of total training trial being 16.8?0.5.Conclusion The decreased hippocampal neurogenesis contributes to retarded learning ability at early pre-pathological lesion stage of TD.

This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

OBJECTIVETo observe the changes of electrocardiogram (ECG) and pregnancy outcome of the late pregnancy women.

METHODSLate pregnancy women were divided into two groups by age: over 35 group and under 35 group. The incidence of abnormal electrocardiogram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there's low birth weight newborn were recorded later.

RESULTSThe incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group (P < 0.05). And the incidence of ST segment changes, arrhythmia in the group of former was higher than that in the group of latter (P < 0.05). Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter (P < 0.05). But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group (P < 0.05). The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups (P < 0.05). The incidence of premature birth in over 35 with abnormal ECG group was significantly higher than that in over 35 with normal ECG group (P < 0.05). The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group (P < 0.05).

CONCLUSIONThe late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.

The study on the Rauvolfia verticillata (Lour.) Baill., which belongs to Apocynaceae, was carried out to look for its chemical constituents and pharmacological activity. The isolation and purification were performed by chromatography on silica gel, Sephadex LH-20 and ODS (octadecyl silane) open column. The structures of obtained compounds were elucidated on the basis of physicochemical properties and spectral analysis. Three indole alkaloids and one acridone alkaloid were isolated from chloroform layer extract and identified as ajmalicine B (1), sandwicine (2), raunescine (3) and 7-hydroxynoracronycine (4) separately. Ajmalicine B (1) is a new compound belonging to indole alkaloid. Compound 4 as an acridone alkaloid was a new type compound isolated from Rauvolfia genus for the first time. We also did some biological activity research on the new type compound (4) to explore other pharmacological activities in addition to antihypertensive activity.

It was long believed that platelets are prematurely destroyed in the reticuloendothelial system by platelet autoantibodies in idiopathic thrombocytopenic purpura. However, humoral mechanisms cannot account for all observations made in this disorder, and it is increasingly evident that cellular mechanisms contribute to platelet destruction. In this review the tolerance of T cell, abnormality of T cell apoptosis, abnormal activation of T cells, T cell subtype and its function changes, and T cell-mediated cytotoxicity were summarized.
