Severe tick infestation was found in a hare in a suburban area of Nanchang, Jiangxi Province, China. We sampled ticks and identified them based on their morphologic characteristics. Three species, Ixodes sinensis, which is commonly found in China and can experimentally transmit Borrelia burgdorferi, Rhipicephalus haemaphysaloides, and Haemaphysalis longicornis which can transmit Lyme disease were detected with an optical microscope and a stereomicroscope. Risk of spreading ticks from suburban to urban areas exists due to human transportation and travel between the infested and non-infested areas around Nanchang.

OBJECTIVETo evaluate the occupational safety climate in different types of enterprises and its relationship with occupational accidental injury.

METHODSA cross-sectional survey based on self-report questionnaires was performed among 3311 front-line workers from 54 medium and small-sized manufacturing enterprises of different types in Zhongshan, China to investigate the socio-demographic characteristics, safety climate experience in workplace, and incidence of occupational accidental injury in the past year.

RESULTSAnalysis of the data revealed that employees in different types of companies perceived different levels of safety climate, according to the scores on four subscales; the European and American enterprises had significantly better safety climate than the Hong Kong and Chinese private enterprises (P < 0.01). The self-reported rates of occupational injury were 3.38%, 4.76%, and 6.72%, respectively, for European and American, Hong Kong, and Chinese private enterprises (χ(2) = 6.78, P < 0.05). After control of such factors as age, sex, income, education level, and marriage, the logistic regression analysis showed that the risk of occupational accidental injury in the European and American enterprises was significantly lower than that in the Chinese private enterprises (OR = 0.57, 95%CI = 0.35-0.91).

CONCLUSIONThe type of enterprise influences the occupational safety climate and incidence of occupational injury among workers.

OBJECTIVETo evaluate the association between occupational stress, social support, and occupational unintentional injuries.

METHODSA 1:1 matched case-control study was conducted in 151 cases of occupational unintentional injuries who were admitted to 6 occupational injury-admitted hospitals in Zhongshan City from October 2013 to December 2013 and 151 matched controls without unintentional injuries in the last year who had matched age, sex, and occupation. Their demographic characteristics, occupational stress (by the effort-reward imbalance questionnaire), and social support were investigated with a structured questionnaire.

RESULTSAnalysis of the data showed that there were significant differences in the score of each dimension of occupational stress, the ratio of effort to reward, and the score of superior support between the case group and the control group (P < 0.05). The Cox regression analysis results showed that more extrinsic efforts (OR = 1.47, 95%CI = 1.20∼1.80) and over commitment (OR = 1.30, 95%CI = 1.08∼1.55) were the risk factors for occupational unintentional injuries, while more superior supports (OR = 0.64, 95%CI = 0.48∼0.84) and higher earnings (>3 000 yuan each month) (OR = 0.67, 95%CI = 0.54∼0.84) were protective factors.

CONCLUSIONOccupational stress and social support have an influence on the occurrence of occupational injuries.

This study measured the in vitro inhibitory effects of α-amylase(AM), α-glycosidase(AG)and aldose reductase(AR)extraction from Potentilla fruticosa in three solvents: water extract(WE)and 95% methanol extraction of petroleum ether part(MEP), 95% methanol extraction of ethyl acetate part(MEE)and 95% methanol extraction of water part(MEW)through α-amylase inhibitors(AMI), α-glycosidase inhibitors(AGI)and aldose reductase inhibitors(ARI)activity screening models. In vivo effects of different solvents from Potentilla fruticosa on impaired glucose tolerance of mice were also measured. Among them, WE, MEP and MEE exhibited against AMI activity with IC50 values of 0. 432, 1. 193 and 0. 507 mg/mL, respectively. Three solvents against AGI activity with IC50 values of 0. 164, 0. 768 and 0. 466 mg/mL, respectively. Three solvents against ARI activity with IC50 values of 0. 742, 2. 158 and 1. 098 mg/mL, respectively. The study suggests that Potentilla fruticosa in water extract and 95% methanol extraction of ethyl acetate part demonstrated a stronger inhibitory effect on AM, AG and AR. Meanwhile, Potentilla fruticosa in water extract and 95% methanol extraction of ethyl acetate part can be significantly decreased the postprandial blood glucose in mice.

Objective To analyze the serotypes and antimicrobial susceptibility profile of Group B Streptococcus (GBS) in perinatal pregnant women.Methods The vaginal and rectal specimens were collected from pregnant women at 35 to 37 weeks of pregnancy for culture and identification.The serotypes were analyzed using agglutination assay.Antimicrobial susceptibility testing was conducted by using Kirby-Bauer method,and interpreted according to 2009 CLSI breakpoints.The data were analyzed via WHONET 5.6 software.Results The prevalence of GBS was 10.4％ (264/2 533) in the 2 533 perinatal pregnant women.Serotype Ⅲ,Ⅰa and Ⅰb was identified in 54.9％ (84/153),17.6％ (27/153) and 13.1％ (20/153) of the GBS,respectively.All the GBS isolates were susceptible to penicillin,cefiriaxone and vancomycin.But 32.9％,68.1％ and 62.1％ of the isolates were resistant to levofloxacin,erythromycin and clindamycin,respectively.The antibiotic resistance rate of serotype Ⅲ isolates to the above three antibiotics was significantly higher than the other serotypes.Conclusions GBS may colonize both vagina and rectum of pregnant women.Vaginal and rectal secretions should be sampled simultaneously for better screening GBS.GBS serotype Ⅲ was the predominant serotype.Penicillin can be used as the first-choice treatment for GBS infections in pregnant women and newborns.GBS-positive pregnant women should be given the intervention treatment immediately to ensure the health of perinatal infants.
