Complex genetic variation has been known to occur during the transmission of human enterovirus (HEV), and the HEV virulence and pathogenicity enhanced by genetic recombination also pose a serious threat to human health. In recent years, the interest in recombination mechanism of genetic plasticity has been renewed with the emergence of pathogenic recombinant circulating vaccine-derived polioviruses, which were implicated in poliomyelitis outbreaks in several regions of the world with insufficient vaccination coverage. This paper reviews recent research progress in HEV genome, including evolutionary characteristics, recombination types, and in vitro recombinant construction.

A HPLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to establish a determination method for drug concentrations of costunolide (Co) and dehydrocostuslactone (De) in blood samples in the positive ion mode, with diazepam as the internal standard substance, in order to study the pharmacokinetic process of sesquiterpene lactones costunolide and dehydrocostuslactone after the oral administration of Weichang'an pills, and provide an theoretical basis for further studies on the substance basis for the anti-diarrhea effect of Weichang'an pills. In the blood samples, Co and De showed a good linearity within concentration ranges 0.700 0-769.7, 2.510-956.0 μg x L(-1), respectively. The results of precision, stability and recovery experiences proved the stability and reliability of the plasma concentration determination method. After the oral administration, the concentrations of Co and De in plasma increased with the increase in dose, with T(max) between 10.65-12.98 h, indicating a long time to reach peak plasma concentrations; C(max) of costunolide and dehydrocostuslactone ranged between 3.750-5.450,15.34-44.52 μg x L(-1), respectively. The in vivo adsorption of Co and De conformed to the one-compartment model, with a longer time to attain the peak plasma concentrations. These results provided an experimental basis for revealing the active substance basis and clinical medication of Weichang'an pills.

Abstract: - （ ） ， Work related musculoskeletal disorders WMSDs are common occupational diseases in construction workers which have a high prevalence rate and involve a large number of construction workers. WMSDs affect daily work and quality of life of ， patients leading to absenteeism and burden. The main body parts of construction workers suffering from WMSDs are lower back/ ， ， ， ， ， waist neck shoulder knee elbow and hand/wrist and most of the patients are complicated in multiple sites. The prevalence ， of WMSDs varies by site with the lower back/waist being the most common sites. The influencing factors of WMSDs in （ ， ， ， ， ， construction workers mainly include individual factors age years of work gender smoking status sleep habits physical ， ）， （ ， ， ， fitness and physical exercise etc. occupational factors work load job type working posture work organization and ， ） management working environment and social psychological factors. The incidence of WMSDs is the result of multiple factors. ， ， Therefore tertiary prevention is the key to the prevention and control of WMSDs especially the etiological prevention. Chinese ， construction industry is in the period of rapid development and the demand of construction workers is large. It is urgent to carry out epidemiological and intervention studies on WMSDs for construction workers to guide the formulation of relevant guidelines and measures for prevention and control of WMSDs.
