Objective To investigate the clinic characteristics,therapeutical approaches and outcome of food-borne infection caused by Group C,Type? hemolytic streptococcus.Methods We retrospectively analyzed 51 patients infected by Group C,Type? hemolytic streptococcus who were hospitalized in the First Hospital of Hebei Medical University from May to June 2003.Results All the patients had eaten the same food which was infected by Group C,Type ? hemolytic streptococcus.The clinical manifestations were 51 pharyngal hyperaemia(100%),44 fever(86%),39 tonsillitis(76.5%),31 headache(60.8%)and 23 ache from head to foot(45.1%).There was no obvious digestive symptom.Seventeen cultivated pharyngal swab samples had all positive results,and 23(52.3%)of 44 cultivated collutory samples were positive.The cultivated bacteria were all Group C,Type? hemolytic streptococcus equisimilies.All the patients were cured after antimicrobial therapy,and hadn't get any complication.Conclusion Infection caused by Group C,Type? hemolytic streptococcus should be considered if the patients have the same food and have such symptoms as fever,headache,ache from head to foot,pharyngal hyperaemia and tonsillitis.Diagnosis can be confirmed with the positive cultivated result of pharyngal swab and collutory.The patients without serious basic disease will have good prognosis after effective and timely therapy.

Objective This study aimed to evaluate the potential predictive factors for carcinomatous transformation of gastric low-grade intraepithelial neoplasia (LGIEN) on the basis of endoscopic features.Methods The study involved 312 gastric LGIENs that were histologically confirmed by endoscopic forceps biopsy (EFB) between May 2004 and September 2010,and then removed by endoscopic mucosal resection or endoscopic submucosal dissection were enrolled in this study.According to EMR/ESD postoperative pathological findings,they were divided into LGIEN group and the HGIEN group,and compared their endoscopic characteristics.Results There were not significant different between the two group,as the mean age、gender the diameter of the lesions、lesion sites and surface nodularity.The diameter of the lesions was 14.6 ± 8.2 mm in the LGIEN group and 22.0 ± 0.55 mm in the HGIEN group (P ＜ 0.05).42 of 69 gastric adenomas (60.9％)larger than 20 mm in diameter showed HGIEN (P ＜ 0.05).Hyperemia and mucosal ulceration were significant differences in the two groups.Conclusion The LGIEN lesions with these endoscopic characteristics,such as size (＞ 2 cm),surface hyperemia,ulceration should be considered for EMR/ESD.

The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.
