The socioeconomic status of the patients is the important factor for post-exposure prophylaxis (PEP). However, few investigations were designed to study the correlation between the socioeconomic status and PEP. This study set out to determine the importance of socioeconomic status for PEP. All of the 11,670 at-risk populations of rabies in the public health centre of San Sheng County in Chengdu from January 2002 to December 2009 were reviewed retrospectively. We identified 11,350 patients on vaccination and 550 patients with rabies immunoglobulin. RIG was administered to 4.85% bite victims attending the rabies prevention clinics, while 61.36% had a category III exposure. The incidence of receiving RIG in the population of the high level of income (49.38%) was much higher than the groups of the medium level (8.08%) and the low level of income (1.46%) (P<0.05). The incidence of receiving RIG with above high school (23.08%) was much higher than the groups of the primary school (3.01%), the junior school (12.56%) and the illiteracy (2.08%) (P<0.05). In the logistic regression analysis by stepwise approach, the socioeconomic status was the most important factor for PEP (95% CI 1.20-2.04). Vaccination and immunoglobulin proved to be the most prominent two factors for PEP but whether receiving Vaccination and immunoglobulin treatment or not is determined by the socioeconomic status. So, the socioeconomic status was the most important factor for PEP. © 2010 Elsevier Ltd.

Background and Aims: We targeted to investigate the efficacy and the mechanisms of two gastric bypass surgeries, Roux-en-y Gastric Bypass (RYGB) and Billroth II gastrojejunostomy on managing obese patients with T2DM and nonobese T2DM patients, respectively. Methods: Seven nonobese T2DM patients with gastric cancer submitted to Billroth II gastrojejunostomy were compared with nine obese T2DM patients undergoing RYGB about their baseline characteristics, weight loss and glycemic control, 3 months and 2 years after surgery. Meanwhile, β-cell function, glucagon-like peptide 1 (GLP-1), peptide YY (PYY) and gastric inhibitory polypeptide (GIP) levels were also investigated. Results: Significant weight loss and improvement of glycemic control were observed in both groups and in the two follow-up periods. Reduction of body mass index was greater in obese patients with T2DM. The efficacy of Billroth II gastrojejunostomy on controlling blood glucose of nonobese T2DM was similar to that of RYGB on managing obese T2DM. Insulin levels and HOMA-IR were decreased in obese T2DM patients, whereas they remained unchanged in nonobese T2DM patients. Generally, levels of GLP-1 and PYY were increased, whereas GIP levels were decreased in both groups. Conclusions: Glycemic control efficacy of Billroth II gastrojejunostomy on managing nonobese T2DM is similar to that of RYGB on treating obese T2DM in the short- and mid-term. The underlying mechanisms of both surgeries may be related to weight loss and gut hormone modulations. © 2015 IMSS.

A large outbreak of novel influenza A (H1N1) virus (swine origin influenza virus) infection in Milwaukee, Wisconsin, USA, occurred in late April 2009. There were a few reports of patients with neurologic complications associated with H1N1 virus infection. We report a patient in China with neurologic complications associated with novel influenza A (H1N1) virus infection to alert clinicians to it. © 2010 Taiwan Medical University.

Background and Aims: Roux-en-Y gastric bypass (RYGB) is effective in controlling blood glucose in obese patients with type 2 diabetes (T2DM). The alterations of gut hormones involving in glucose metabolism may play an important role. Our aim was to explore the short-term effects of Billroth II gastrojejunostomy (a similar type of RYGB) on glucose metabolism and gut hormone modulations in nonobese patients with different levels of blood glucose tolerance. Methods: Twenty one nonobese gastric cancer patients with different levels of blood glucose tolerance were submitted to Billroth II gastrojejunostomy. Among them, seven had T2DM, seven with impaired glucose tolerance (IGT) and the other seven had normal glucose tolerance (NGT). Body weight, glucose parameters, responses of plasma glucagon-like peptide-1 (GLP-1), peptide YY (PYY) and gastric inhibitory polypeptide (GIP) to 75 g glucose were measured at baseline and 3 months after surgery. Results: Similar weight losses were observed in all groups. Blood glucose was reduced in T2DM and IGT patients. Fasting and 30-min plasma glucose were increased significantly in NGT. GLP-1 showed insignificant alterations in all groups. PYY was evaluated in T2DM and IGT but remained unchanged in the NGT group. Decreased fasting and AUC GIP were observed in patients with T2DM; however, fasting and 30-min GIP were increased in NGT patients. Conclusions: Billroth II gastrojejunostomy is effective in reducing blood glucose in nonobese patients with T2DM and IGT but could deteriorate early blood glucose in nonobese NGT in a 3-month time period. Variations of glucose and gut hormone changes in the three groups suggest a role of proximal intestine in the pathophysiology of T2DM. © 2013 IMSS.

Background: Although Helicobacter pylori infection is necessary for development of gastric adenocarcinoma (GAC), the underlying mechanism remains poorly defined. This study aimed to explore how miR-221 and miR-222 are dysregulated after H. pylori infection and how these 2 miRNAs are involved in pathological development of gastric cancer. Material/Methods: qRT-PCR analysis was performed to quantify miR-221 and miR-222 expression in patients with H. pylori – induced chronic gastritis, H. pylori-negative healthy controls, and in gastric cancer tissues and the corresponding adjacent normal tissues. Cell models were used to verify the expression profile. Dual luciferase assay was performed to verify putative binding between miR-221 or miR-222 and RECK. A loss-and-gain function study was performed to assess the miR-221/miR-222-RECK axis in gastric cancer cells. Results: H. pylori infection leads to significantly higher miR-221 and miR-222 expression. MiR-221 and miR-222 can bind the same sequence of RECK 3’UTR, thereby modulating its expression. Through simultaneous regulation over RECK, miR-221 and miR-222 can promote gastric cancer cell growth and invasion. Conclusions: The miR-221/miR-222-RECK axis might be an important path modulating H. pylori infection-related gastric cancer development. © Med Sci Monit, 2015.
