OBJECTIVETo explore the clustering character of overweight and obesity with multiple cardiovascular disease risk factors such as blood pressure, serum lipids and glucose, and to provide evidence for intervention in childhood.

METHODSA cross-sectional study was conducted on 913 children aged 7-13 years in urban area of Shijiazhuang. Measurements included height, weight, systolic blood pressure (SBP), diastolic blood pressure (DBP) and fasting serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and serum glucose (GLU).

RESULTSOverall prevalence rate of overweight and obesity was 29.24% (boys: 34.98% vs. girls: 24.23%). When compared with normal children, children with overweight or obesity had significantly higher levels of SBP, DBP, TC, TG but low HDL-C. The prevalence rates of high SBP, DBP, TC, TG, GLU and low HDL-C in overweight and obese children were higher than in normal children. After adjusted for gender and age, the odds ratios of overweight and obese children for high SBP, DBP, TC, TG, GLU and low HDL-C were 6.77, 3.22, 2.55, 6.42, 3.85 and 2.94 (95% CI: 4.15-11.04, 1.38-7.49, 1.59-4.11, 3.46-11.92, 1.69-8.78 and 1.83-4.73), respectively. Odds ratios of overweight and obese children holding any one, two or three of the selected six risk factors appeared to be 2.74, 13.15 and 15.33 (95% CI : 1.92-3.92, 6.69-25.87 and 4.17-56.39), respectively.

CONCLUSIONChildhood overweight and obesity increased the clustering of children's risk factors on cardiovascular diseases, as well as increasing the risk of children acquiring multiple cardiovascular disease risk factors. Controlling overweight and obesity would help early prevention on children from getting cardiovascular diseases.

OBJECTIVELyme disease and Human granulocytic anaplasmosis are tick-borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum.

METHODSForest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA).

RESULTSSeroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks.

CONCLUSIONWe conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces.

·Rodents have been used widely in the research of eye diseases to study visual function in animal models. Two methods of visual acuity testing in animals have been internationally recognized:the electrophysiological visual acuity test and the behavioral visual acuity test. Both of these methods have their advantages and limitations. The electrophysiology test (visual evoked potential) is invasive, and animals need recovery time after being implanted with electrodes. Also,the electrophysiological visual acuity test only reflects the electrical activity of a single cell or nuclei, it does not reflect the overall visual function of the animal. The widely used behavioral visual acuity test is able to compensate for these limitations. This paper gives a brief overview of the methods of the behavioral visual acuity test for rodents (rats, mice, guinea pigs,etc.).

Objective To understand the infection status and risk factors of Entamoeba histolytica in inpatients in Tengchong City, Yunnan Province. Methods A cross-sectional study was conducted in the inpatients in Tengchong People’s Hospital, Yunnan Province. After obtaining the informed consent from the subjects, the stool samples were collected from 2016-07-01 to 2017-03-31, and nested polymerase chain reaction (PCR) was used to detect E. histolytica in the stool samples. Meanwhile, a structured questionnaire was used to record the demographic information and clinical symptoms for the patients. Results Totally 507 cases were recruited, and the detection rate of E. histolytica was 1.97% (10/507, 95% CI: 1.07%-3.59%) in all subjects. There were no significant differences between the inpatients with and without E. histolytica infection in the height (Z = -0.40, P = 0.69), weight (Z = -0.34, P = 0.73), body mass index (Z = -0.40, P = 0.69) and age (Z = -1.48, P = 0.14). Chronic diarrhea (OR = 21.43, 95% CI: 5.04-91.23) and daily drinking water (OR = 11.28, 95% CI: 2.79-45.56) were relevant to E. histolytica infection. No significant association was observed between E. histolytica infection and the clinical symptoms, such as abdominal distension (OR = 0.70, 95% CI: 0.09-5.56), inappetence (OR = 0.50, 95% CI: 0.06-4.02), itchy skin (OR = 0.79, 95% CI: 0.10-6.38), perianal pruritus (OR = 1.74, 95% CI: 0.21-14.07), and constipation (OR = 0.91, 95% CI: 0.13-7.33). Conclusion E. histolytica infection is high in inpatients in Tengchong City, Yunnan Province, and chronic diarrhea and drinking unboiled water were highly correlated with E. histolytica infection.

5-Hydroxymethylfurfural (5-HMF), a water-soluble compound extracted from wine-processed Fructus corni, is a novel hepatic protectant for treating acute liver injury. The present study was designed to investigate the protective effect of 5-HMF in human L02 hepatocytes injured by D-galactosamine (GalN) and tumor necrosis factor-α (TNF-α) in vitro and to explore the underlying mechanisms of action. Our results showed that 5-HMF caused significant increase in the viability of L02 cells injured by GalN/TNF-α, in accordance with a dose-dependent decrease in apoptotic cell death confirmed by morphological and flow cytometric analyses. Based on immunofluorescence and Western blot assays, we found that GalN/TNF-α induced ER stress in the cells, as indicated by the disturbance of intracellular Ca(2+) concentration, the activation of protein kinase RNA (PKR)-like ER kinase (PERK), phosphorylation of eukaryotic initiation factor 2 alpha (eIF2α), and expression of ATF4 and CHOP proteins, which was reversed by 5-HMF pre-treatment in a dose-dependent manner. The anti-apoptotic effect of 5-HMF was further evidenced by balancing the expression of Bcl-2 family members. In addition, the knockdown of PERK suppressed the expression of phospho-PERK, phospho-eIF2α, ATF4, and CHOP, resulting in a significant decrease in cell apoptosis after the treatment with GalN/TNF-α. 5-HMF could enhance the effects of PERK knockdown, protecting the cells against the GalN/TNF-α insult. In conclusion, these findings demonstrate that 5-HMF can effectively protect GalN/TNF-α-injured L02 hepatocytes against ER stress-induced apoptosis through the regulation of the PERK-eIF2α signaling pathway, suggesting that it is a possible candidate for liver disease therapy.
