The purpose of this study was to investigate the existence and extent of cognitive impairment in adult diabetes mellitus (DM) patients with episodes of recurrent severe hypoglycemia,by using meta-analysis to synthesize data across studies.PubMed,EMBASE and Cochrane library search engines were used to identify studies on cognitive performance in DM patients with recurrent severe hypoglycemia.Random-effects meta-analysis was performed on seven eligible studies using an inverse-variance method.Effect sizes,which are the standardized differences between the experimental group and the control group,were calculated.Of the 853 studies,7 studies met the inclusion criteria.Compared with control subjects,the adult DM patients with episodes of recurrent severe hypoglycemia demonstrated a significantly lowered performance on memory in both types of DM patients,and poor performance of processing speed in type 2 DM patients.There was no significant difference between adult DM patients with and those without severe hypoglycemia in other cognitive domains such as general intelligence,executive function,processing speed and psychomotor efficiency.Our results seem to confirm the hypothesis that cognitive dysfunction is characterized by worse memory and processing speed in adult DM patients with a history of recurrent severe hypoglycemia,whereas general intelligence,executive function,and psychomotor efficiency are spared.

OBJECTIVETo investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).
METHODSA retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.
RESULTSCompared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.
CONCLUSIONCompared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.

The aim of study was to set up a suitable method of isolation, culture and identification of endothelial progenitor cells (EPC) derived from rabbit bone marrow. Density gradient centrifugation was used to isolate mononuclear cells from bone marrow, the isolated mononuclear cells were cultured with specific culture medium for EPCs. EPCs were identified by cellular morphologic observation, immunohistochemistry testing, flow cytometry and the function test of taking up Dil-ac-LDL and FITC-UEA-1. The results indicated that the newly isolated bone marrow-derived mononuclear cells exhibited a round appearance, following culture for 48 hours, adherent cells grew in colony cluster, presenting with round or irregular appearance, and nuclear division was obvious. On day 7, flaky cell colonies mutually connected together, presenting with spindle-shaped cells. Immunohistochemistry testing in the EPCs showed CD133(+), CD34(+), VIII factor(++), KDR(++); flow cytometry testing showed that the positive rate of CD133 was (18.23+/-7.12)%, the positive rate of CD34 was 47.71+/-14.85%, the positive rate of CD31 was (71.61+/-13.51)%, the positive rate of KDR was (87.24+/-11.40)%. And more than 80% EPC could take up both Dil-acLDL and FITC-UEA-1. It is concluded that the mononuclear cells isolated from bone marrow by density gradient centrifugation can differentiate into EPCs under special culture situation.

OBJECTIVETo investigate the application of titanium mesh and free forearm flap for reconstruction of maxillary defect resulted from tumor resection.
METHODSFrom 2004 to 2008, 19 cases with maxillary tumor underwent tumor resection. The defects were reconstructed immediately with titanium mesh for bony defects and free forearm flap for oral mucosa defects.
RESULTS16 cases achieved satisfactory functional and cosmetic results. The speech assessment was good without oronasal reflux. The titanium mesh was exposed and infected in 3 cases. Then the meshes were taken out and the defects were covered with the forearm flap to close the oronasal fistula. The midface was slightly depressed with no functional morbidity.
CONCLUSIONSIt is simple and practical to reconstruct maxillary defect with titanium mesh and free forearm flap. Both the functional and cosmetic results are satisfactory.

Driven by demand and policy guidance, the construction of Internet hospitals is on a fast track mode in China. To address such a situation, the state requires that before Internet hospitals are admitted, the provincial health authorities should establish an Internet medical service supervision platform to interconnect with the Internet hospital information platform for real-time supervision. This study discussed and introduced the Internet medical service supervision platform in Henan province, covering its system architecture, functions, regulatory indicators and operation mode. The platform is officially in operation and has completed docking with 7 medical institutions. It can implement entire process supervision with a total of 186 indicators in five categories in Henan, providing a reference for the construction of Internet medical service supervision platforms in other provinces.

The present pandemic prevention and control of 2019 novel coronavirus diseases(COVID-19) is still severe in China and abroad, which is however witnessing a dimensional application and success of the information technology.For example, the remote consultation system of epidemic prevention and control had played a key role in Henan province in its fight against COVID-19. The architecture of the system was composed of software and hardware architecture, data exchange technology, security system design, and data collection specifications. By the end of September 2021, the audio and video systems of 147 designated hospitals for patients of COVID-19 had been constructed, and 98 of which had achieved clinical data sharing and interaction. The remote consultation system effectively guaranteed the real-time sharing of case data, saved diagnosis costs and treatment time, laying a solid foundation for the pandemic prevention and control of COVID-19.

OBJECTIVETo investigate the human immunodeficiency virus (HIV) and syphilis incidence rates as well as the retention rate in a cohort with 6-month follow-up study among female sex workers (FSWs).
METHODSFrom December, 2004, to January, 2005, a community-based baseline survey was conducted to recruit 343 FSWs for a prospective cohort study in Xichang county of Sichuan province, China. Follow-up visits were conducted at 6 months to analyze risk factors associated with cohort retention for subjects' baseline sociodemographic and sexual behavioral characteristics. Blood specimens were also collected to test antibodies against HIV and syphilis.
RESULTSDuring the 6-month follow-up period, HIV and syphilis incidence appeared to be 1.00 per 100 person-years and 6.23 per 100 person-years, respectively. The rate of retention in the cohort was 53.6% (184/343). Results from multivariate logistic regression model showed that factors were significantly associated with cohort retention including people with minority ethnic background (OR = 0.36; 95% CI: 0.18-0.74), people having participated in AIDS prevention program (OR = 1.83; 95% CI: 1.17-2.86) or being clients in the last 6 months > or = 50 (OR = 1.75; 95% CI: 1.11-2.77) and having changed living/working place (OR = 0.56; 95% CI: 0.33-0.94).
CONCLUSIONThe results of this study showed that the syphilis incidence and unprotected sex behavior were high among local FSWs. People belonged to Han nationality, having participated in AIDS prevention program and having a steady living/working place were associated with cohort retention at 6-month follow-up study among FSWs, respectively.
