Objective To investigate the effects of joint function screening and correction on intervention efficacy of prevention and assessment score of training injuries in new recruits.Methods A randomized controlled study was conducted on 265 new recruits subjected from two organizational units of an army unit with cluster sampling.Based on entire organizational unit,the participants were randomly divided into a control group(n=132)and an experimental group(n=133).The experimental group received joint function screening and corrective movement training,which was subsequently applied in the new recruit training,while the control group underwent training according to conventional methods.Joint function were collected before and after training.The demographic data,assessment score of training,and incidence of training injuries were collected through the participant's own organizational unit.Receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of joint function screening in predicting training injuries,and binary logistic regression and general linear regression analyses were applied to verify the correlation of joint function screening score with training injuries and assessment score of training.Results After new training,the score of joint function screening was significantly higher in the experimental group than the control group(16.62±1.87 vs 14.92±2.58,P<0.001).And the score was obviously increased in the experimental group(16.62±1.87 vs 12.82±1.98,P<0.001)and the control group(14.92±2.58 vs 12.95±1.81,P<0.001)when compared with the corresponding score before training.The area under the ROC curve(AUC)of joint function screening in predicting training injuries was 0.762(95%CI:0.694～0.830),indicating good predictive efficacy.During the new training process,the incidence of training injuries in the experimental group(13.53%)was significantly lower than that in the control group(24.24%,Chi-square=4.963,P=0.026).Binary logistic regression analysis showed that the pre-training assessment score of joint function screening was an important influencing factor for training injuries in new recruits(OR=0.552,95%CI:0.413～0.660,P<0.001).The experimental group obtained notably higher mean assessment score than the control group[733.00(716.00,752.75)vs 728.79(710.46,744.28),P=0.027].Linear regression analysis revealed a correlation between post-training score of joint function screening and the assessment score of newly trained personnel(P<0.001).Conclusion Joint function screening and correction for newly trained personnel can effectively prevent training-related injuries during the new training period,and correcting joint function through training can effectively improve the assessment score of newly trained personnel.

Military vocational education has become one of the strategies to strengthen the military in the new era. The army urgently needs to build a number of featured online courses of military vocational education. Therefore, taking the course "Knowledge and Skills of Health Education for the Army" as an example, this paper discusses the overall construction objectives, construction ideas, teaching content, curriculum and test question bank construction of the course. In addition, this paper analyzes and summarizes the problems existing in the teaching organization, implementation, and preliminary application, so as to provide ideas and construction strategies for the construction of online open courses in other military vocational education.

Objective: To estimate the blood concentration of isoflurane with the inspired andexpired concentrations during laparoscopic surgery. Methods: 2 sections were divided in this experiment: section 1:23 adult patients (ASA I～II)were received abdominal surgeries,of whom,12 patients for non-laparoscopic surgeries and the others for laparoscopic surgeries. Central venous blood samples were collected for gas chromatography determination 20, 40, 60, 80 min after inhalating isoflurane . We could receive two different F value (the fraction of uptake of isoflurane)through the formula. Section 2: 27 patients were recruited for abdominal surgeries, 13 for laparoscopic surgeries and the others for non-laparoscopic surgeries. All of the processes were the same as the former. Then we confirm the results obtained from section1. Results: The F was 0.52 in the laparoscopic surgeries and 0.44 in the nonlaparoscopic surgeries. In the laparoscopic surgeries, the bias (MDPE) was 17% , accuracy (MDAPE)was 22.88% and the wobble was 11.7% .The correlation coefficient (r)was 0.83. In the nonlaparoscopic surgeries, the MDPE was 5.37% , the MDAPE was 16.02% , the wobble was 15.86% .The correlation coefficient was 0.90. Conclusion: The formula could be used in abdominal surgeries to evaluate the concentration of isoflurane according to the clinical standard of MDPE
