Objective To explore the patterns of cognitive performance across different clinical states of bipolar disorder(BPD).Methods 8 neuropsychological tests (17 items) which examine attention,verbal learning and memory,visual memory and executive function were given to 30 depressed BPD ,30 manic BPD ,30 remitted BPD and 34 normal controls.The difference of cognitive functions between the four groups were compared using multivariate analysis of variance (MANOVA).Results Acute patients with BPD showed dysfunction in almost all neuropsychological tests compared with controls [ the score of WCST categories of manic BPD,depressed BPD,remired BPD and normal controls was( 1.58 ±0.90),( 1.89± 1.56),(2.44 ± 1.42),(4.90 ± 1.73 ) respective-ly.The score of immediately logical memory was (10.68±3.92),(10.00±3.80) ,(12.11±3.72),(15.80±4.21) respectively] (P<0.05,P<0.01).The remitted patients showed deficits in attention,verbal learning and memory,executive function tasks in relation to controls (P<0.05,P<0.01).Conclusion There were general cognitive deficits in acute patients with BPD,and some of these deficits may persists in remission state.

BACKGROUND:Whether a long-term use of acid-suppressive medication for over 3 years can increase the risk of fractures, remains controversial.
OBJECTIVE:To systematical y review the effect of acid-suppressive medication on fracture risk.
METHODS:Clinical trials about the relationship of acid-suppressive medication use and risk of osteoporosis-related fractures were searched in MEDLINE, Cochrane Library, EMbase, and CNKI database. We also manual y searched some published and unpublished references. Study selection and assessment, data col ection and analyses were undertaken by two reviewers independently. The Cochrane Col aboration’s RevMan 5.0 software was used for data analyses.
RESULTS AND CONCLUSION:After a comprehensive search, 11 original clinical trials were included in this meta-analysis, including 3 nested case-control studies, 5 case-control studies, and 3 cohort studies. Patients with fractures were more likely than controls to have previously received supply of proton pump inhibitors [odds ratio (OR)=1.29, 95%confidence interval (CI) (1.18-1.41), P<0.001]. The meta-analysis did not find a significant difference in the patients who received H2 receptor antagonists [OR=1.10, 95%CI (0.99-1.23), P=0.34]. A long-term use of proton pump inhibitors is associated with an increased risk of fracture in elderly persons already at a risk for osteoporosis.

Objective:To explore the therapeutic effect of procaine plus compound salvia miltiorrhiza injection in the treatment of Henoch-Schonlein Purpura (HSP) associated with stomachache.Method:35 cases of Pedo-HSP were ran- domly divided into two groups.The experimental group was treated with the compound salvia mihiorrhiza injection in addi- tion to the routine treatment and the controlled group received the routine treatment only.Result:The time of relief and dis- appearance of stomachache and average days were much shorter in the experimental group than in the controlled group (p

Objective To explore the effect and its mechism of osteoprotegerin (OPG) on human umbilical vein endothelial cells(HUVECs) induced by high glucose.Methods (1) The cultured HUVECs were treated with normal glucose(5.5 mmol/L),high glucose(33 mmol/L),high glucose + OPG(0.5,1,and 2 μg/ml)as well as mannitol(5.5 mmol/L glucose+27.5 mmol/L mannitol) for 48 h,respectively.Flow cytometry assay and Hoechst 33258 staining were used to detect the cell apoptosis.The expression levels of Bcl-2 and Bax protein were measured by western blot analysis.(2) The cultured HUVECs were treated with normal glucose,high glucose,high glucose + OPG (2 μg/ml OPG),high glucose + rapamycin(10 ng/ml rapamycin) as well as high glucose + rapamycin + OPG for 24h,respectively.The expression levels of S6K,p-S6K,4EBP1 and p-4EBP1 protein were measured by western blot analysis.(3)The cultured HUVECs were treated with normal glucose,high glucose,high glucose + OPG(2 μg/ml)for 24 h,respectively.The expression levels of tuberin and p-tuberin protein were measured by western blot analysis.Results (1) Compared with normal glucose group,the apoptosis of HUVECs and the expression level of Bax was dramatically increased,and the expression of Bcl-2 was decreased significantly in high glucose group (P＜0.05).The apoptosis of HUVECs and the expression level of Bax in high glucose + OPG group was significantly lower than that in high glucose group,which was still higher than that in normal glucose group (P＜ 0.05).and the expression of Bcl-2 in high glucose + OPG group was significantly higher than that in high glucose group,which was still lower than that in normal glucose group (P＜0.05).There was no statistically difference between hyperosmolar control group and normal glucose group.(2) Compared with normal glucose group,the expression levels of p-S6K and p-4EBP1 were increased markedly in high glucose group(P＜0.05).The expression levels of p-S6K and p-4EBP1 in high glucose + OPG group were significantly lower than that in high glucose group,which were still higher than that in normal glucose group(P＜0.05).No significant difference was found between high glucose + OPG group and high glucose + rapamycin group.(3) Compared with normal glucose group,the expression level of p-tuberin was increased markedly in high glucose group (P ＜ 0.05).The expression level of p-tuberin in high glucose + OPG group was significantly lower than that in high glucose group,which was still higher than that in normal glucose group (P ＜0.05).Conclusions It suggests that the protective effect and mechanism of OPG on HUVECs cultured with high glucose may be association with tuberin/mTORC1 pathway.

Four-week-old male Sprague-Dawley rats were rendered diabetic by intraperitoneal injection of streptozotocin (STZ) after feeding high-fat-diet for 8 weeks,and divided into diabetes group and tumor necrosis factorrelated apoptosis ligand(TRAIL) group.Normal rats severed as a control group.Treatment with TRAIL lasted for 3 months.Total cholesterol,triglycerides,low-density lipoprotein-cholesterol,blood glucose,and insulin levels were decreased in TRAIL group,as compared with diabetes group.Area of atherosclerotic lesion in TRAIL group [(23.8 ± 5.7) ％] was significantly smaller than that in diabetes group [(47.6 ± 7.8) ％].It suggested that TRAIL may reduce the area of atherosclerotic lesion in diabetic rats.

A thiosulfate-oxidizing bacterium TX was isolated from polysulfide wastewater treatment system.It was preliminarily identified as Halothiobacillus sp.according to its morphological,physiological proper-ties and similarity analysis of 16S rRNA gene sequence(GenBank accession No.EU871645).This bacte-rium was an obligate chemolithoautotrophic sulfur-oxidizing bacterium since it could utilize thiosulfate,elemental sulfur,tetrathionate,sulfide or sulfite as sole energy source but did not show growth on the me-dium with glucose,sucrose,fructose,lactose,mannose or yeast extract as sole carbon source.The optimal growth condition for thiosulfate oxidation was 30?C~35?C and pH 3.0~5.0 respectively.Significant reduc-tion in medium pH from 4.0 to 1.2 was observed due to oxidation of thiosulfate to sulfate during the batch culture incubation period.During the course of thiosulfate oxidation accumulation of tetrathionate was ob-served either in synthetic medium or in the mixed liquor from aeration tank of the polysulfide wastewater treatment system.This indicates that the "S4 intermediate(S4I)" pathway was responsible for thiosulfate oxidation in this bacterium.

There is a variety of gut microbiota in human body, which is closely associated with the health and disease. Normal gut microbiota can produce colonization resistance to pathogens. Antibiotics can affect the composition of gut microbiota and change the intestinal microenvironment, resulting in intestinal microecological disorders, which in turn cause intestinal pathogenic infections and other diseases. In this paper, the concept of intestinal microecology, the mechanism of intestinal colonization resistance, the effect of antibiotics on intestinal microecology, and the treatment methods were reviewed, aiming to provide the information for the rational use of antibiotics and the development of more effective treatment methods to maintain the stability of intestinal microecology.
