The total protein of Toxoplasma gondii RH strain tachyzoites was separated by two-dimensional electrophoresis (2-DE), and Western blotting was performed to find out distinct antigens. 209 spots were detected through Coomassie brilliant blue-stained small gels (7?8 cm, pH 3-10). Western blotting showed 17 specific antigen spots with sera of the experimental group and two nonspecific spots with the control sera.

By means of a comprehensive coverage of the numbers,distribution,makeup and efficiency of health human resources in China,a comparative study was made as to the deployment for the present stage.It reveals the following findings:sufficient human resources in general,with its growth lagging behind economic development; out-of-balance deployment; irrational makeup as shown in the inverse ratio between doctors and nurses; good efficiency of the health professionals.Based on these findings,the researchers put forward the feasible policy suggestions as to optimizing the mechanisms of the introduction,training,evaluation and incentives for these professionals.

Objective To investigate effects of high fat-salt diet on change of growth and development,body fat distribution insulin sensitivity and associated metabolic indexes for juvenile rats. Methods 50 grams of male,female SD juvenile rats (3 weeks,just weaned) were randomly divided into 3 groups,12-14 animals in each group,were given routine diet (NC) and high fat diet (FC) and high fat-salt diet (FSC) .Then the body weight,,body length,abdominal circumference,blood pressure,visceral fat weight,plasma lipids were measured 4 weeks later,at the same time oral glucose tolerance test and insulin release test were performed. Results In the FSC group,body weight,abdominal circumference,blood pressure,visceral fat,plasma glucose and insulin level significantly increased than the NC group,plasma lipid disorders increased and significant insulin resistance occurred. Conclusion High fat and high salt could successfully induced obesity,hypertension,dyslipidemia and impaired glucose tolerance.

Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.
