ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

Objective To evaluate the methodological quality of clinical trials on Chinese medicine interventional chemothera-py induced gastrointestinal toxic reactions from 2000 to 2014.Methods The randomized controlled trials(RCT)and semi-RCT on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions were retrieved from the China National Knowledge Infrastructure (CNKI),Wanfang databases,VIP,China Biology Medicine Database (CBM)and Traditional Chinese Medicine (TCM)database by computer and supplemented by the manual retrieval (January 2000 to December 2014).The methodo-logical quality assessment on the included RCT and semi-RCT was conducted by using the Cochrane risk assessment table of bias. Results 291 articles were finally screened out,only 76 of RCT and semi-RCT were conformed to the at least one of low risk stand-ards of Cochrane risk assessment table of bias.Therefore the total methodological quality was not good enough.Conclusion The publishing of clinical trials on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions shows the in-creasing trend year by year during the past 14 years.However,the different defects exist in the overall trial design.

AIM:To explore the role of α7 nicotinic acetylcholine receptor (α7nAChR) in anti-inflammation of glucocorticoids (GCs) at physiological concentrations .METHODS: MTT assay was used to measure the viability of BV-2 cells, which were processed by hydrocortisone at different concentrations .On the basis of inflammatory model induced by LPS in BV-2 cells, experimental groups were divided as follows:(1) control;(2) LPS;(3) GCs+LPS;(4) methyl-lycaconitine ( MLA)+GCs+LPS.The levels of TNF-αand IL-1βin the cell supernatants were detected by ELISA .RE-SULTS:Hydrocortisone at concentrations of 2 000 and 1 000 nmol/L decreased the cell viability to (76.9 ±5.5)% and (90.8 ±7.3)%, respectively, indicating the cellular injury by GCs at over-physiological doses.LPS significantly induced the releases of TNF-αand IL-1βin a time-and dose-dependent manner in BV-2 cells.Hydrocortisone at physiological con-centrations (500 and 250 nmol/L) reduced the releases of TNF-αand IL-1βin BV-2 cells stimulated by LPS, and MLA at concentration of 10 nmol/L antagonized the anti-inflammatory effect of GCs .CONCLUSION:α7nAChR is involved in the anti-inflammatory effect of the physiological concentrations of GCs .

Proteome is defined as all proteins expressed in a cell, a tissue or an organism. Proteomics, a science of understanding the life activity law at the whole protein level, takes proteome as a research object; it is also a scientific method for quantitative detection of one or more protein populations or proteomes in a cell or tissue. Cerebral ischemic preconditioning has been one of the research hotspots in the field of neuroscience for decades. Its neuroprotec-five mechanism is associated with the changes of protein expression levels after cerebral ischemia, Therefore, proteomics has become more and more important in its mechanism study. This article mainly presents the major techniques of proteomics and their application in the studies of cerebral ischemic preconditioning.

Bovine Lactoferricin is a fragment of polypeptide which derives from N-terminal of bovine lactoferrin when it is digested by pepsin in acid condition. It has many biological functions. This study was designed to research the antibiosis spectrum of LfcinB and the key functional active site of the LfcinB by amino acid substitution and peptide sequence modification. Antimicrobial spectrum of the artificial synthesized LfcinB was determined by agar-well diffusion method. The antibacterial active sites were confirmed by minimal inhibitory concentration assays. After the Cysteine at the third site and the tryptophan at the eighth site of LfcinB were substituted by alanine, or two cysteine of LfcinB were respectively, the minimal inhibitory concentration of the three artificially modified LfcinBs was assayed. Results showed that LfcinB had a broad-spectrum of antibiosis, it could restrain various bacterials, such as Gram-positive bacteria, Gram-negative bacteria, fungus and mycetes. LfcinB was stable to heat and pH, it could not be inactivated by many protease. The tryptophan at the eighth site and the intramolecular disulfide bond formed between two cysteins played a key role for antibiosis, as the functional active sites of LfcinB.

Objective To investigate the state of glucocorticoid(GC) - induced osteoporosis (GIOP) and the current prevention of GIOP in patients with primary glomerulonephritis. Methods Primary glomerulonephritis patients receiving GC therapy were observed and bone mineral density (BMD) in the lumbar spine and the femoral neck were measured. Age, sex, body - mass - index, smoking history, the time and accumulative dose of GC treatment, and the state of osteoporosis prevention were investigated, the factors that influence the BMD were analyzed. Results A total of one hundred and twenty- three patients were included in this study. Among them, osteoporosis and os-teopenia were found in 82 patients (66.7%). Lumbar spine BMD decrease gradually with the increase of the accumulative dose of GC. There were statistical differences in the BMD of lumbar spine in patients with receving GC at the period of less than 1 month compared with other groups( 1-12 months) (P

OBJECTIVE:To study the incidence,types,constitution ratio of adverse drug reactions(ADR)induced by antibiotics and the correlation factors of the ADR so as to promote rational drug use in our hospital.METHODS:The literature about antibiotics-induced ADR from Jan.1980 to May 2008 retrieved from CNKI,Wanfang Data and VIP full-text data base was analyzed quantitatively by dividing the literature into different categories:case study or typical case reports,clinical trial or observational reports,and regional ADR monitoring data base or hospital ADR analytical reports.RESULTS:There were 2 310 case studies or typical case reports and in which 3 794 ADR cases were reported,which manifested chiefly as allergic reaction(35.58%),nervous system reaction(17.82%)and disulfiram-like reaction(in 546 cases).928 papers were literature about clinical trial or observational reports and in which 9 434 ADR cases were reported and the average ADR incidence was 9.14%,with anti-tuberculosis drugs showing the highest proportion(25.57%),followed by nitromidazole(24.29%)and carbapenem antibiotics(23.52%);and the ADR manifested chiefly as gastrointestinal tract reaction and allergic reaction,and there were ADR cases manifested as pathoglycemia induced by quinolones.There were 300 papers were literature about regional ADR monitoring data base or hospital ADR analytical reports,in which almost all the major variety of antibiotics were involved,leading the list in terms of ADR cases were quinolones,penicillins and cephalosporins.CONCLUSION:Great importance should be attached to the rational use of antibiotics so as to avoid or reduce ADR incidence and ensure safe and effective use of antibiotics in patients.

Objective To explore the clinical characteristics and diagnosis of primary small intestinal tumor(PSIT). Methods Retrospective analysis of the clinical and pathological data of the 31 PSIT cases was made. Results Duodenum was the most common site 67.74% for PSIT. The confirmed diagnosis rate was 54.84%(17/31)(duodenum was 66.67%,14/21; ileum and jejunum was 30%, 3/10, respectively ). 3 cases were benign tumors and 28 were malignant tumors.The adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and often in duodenal. The features of the small intestinal tumor could be abdominal pain,abdominal mass,hemorrhage,obstruction,jaundice and fever.The chief method for diagnose was barium meal X-ray examination, especially with the hypotonic contrast X-ray examination and endoscopy.Superior mesenteric arteriography sometimes helped in determing site of gastrointestinal haemorrhage. CT scan could be helpful in diagnosis. Conclusion Duodenal adenocarcinoma is most common PSIT,followed by malignant lymphoma.Endoscopy is the best way to find out the tumor located in duodenum and hypotonic contrast X-ray examination is effective in diagnosis and locating of small bowl tumors.Superior mesenteric arteriography is a good way to find out angioma and leiomyoma. CT scanning are also helpful.
