Objective To investigate the reliability and validity of a novel hand-held dynamometer, OE-210, for muscles strength of low-er extremities. Methods From March 1st to August 30th, 2016, 38 young adults were tested the muscle strength of quadriceps and ham-strings with OE-210 dynamometer by 2 rators, and were retested by one of the raters three days later. The isokinetic test was also conducted on all the subjects one day afterwards. The intraclass correlation coefficient (ICC) of OE-210 test results and the Pearson's correlation coeffi-cient between results of OE-210 and isokinetic test were calculated. Results The ICC of test-retest were 0.718 to 0.924, and the ICC of in-ter-rater were 0.784 to 0.870. The correlation between muscle performance measured with 2 tools were significant (P<0.001), that was light to medium on quadriceps (r=0.270-0.413), and strong on hamstrings (r=0.582-0.668). Conclusion OE-210 dynamometer was reliable for muscle strength measurement on quadriceps and hamstrings, and the conditions for valid application need further research.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.

This study is to establish an UPLC fingerprint of Resina Draconis from different manufacturers, which can provide a comprehensive evaluation for its quality control. The analysis was performed on a Phenomenex Kinetex 2.6 μ C18 100A column by agradientelution program with acetonitrile-water as mobile phase at a flow rate of 1.7 mL x min(-1). The column temperature was 40 degrees C and the detection wavelengthwas 280 nm. The fingerprints of 18 batches of Draconis Resina were further evaluated by chemometrics methods including similarity analysis (SA), hierarchical clustering analysis (HCA) and principal component analysis (PCA). As a result, there were 15 common peaks, 13 of which had been identified by LC-Q-TOF MS, and the similarity degrees of 15 batches of the samples was more than 0.9, and the samples were divided into 4 clusters by their quality difference. The method is reproducible, simple and reliablethat it can be used for quality control and evaluation of Resina Draconis from different manufacturers.

The effects of application of in-process quality control in Guizhi Fuling capsule production were evaluated by 192 batches data analysis. Using a statistical analysis method, each batch of data were to be counted to research for the difference between 96 samples adopting the technologies of in-process control or not. According to quality standards of Guizhi Fuling capsule, all measurements of the 192 batches of the drugs before and after the application of process control technology were analyzed, and they were within the rules. There was a significant difference between adopting the technologies of process control or not. Application of in-process control technology can improve the uniformity of lot-to-lot for Guizhi Fuling capsule.

Objective To evaluate the impact of breathing motion on target volume and the factors influencing the set-up errors during tangential whole breast irradiation.Methods From Jan 2003 to Dec 2003,patients with early-stage breast cancer after breast conserving surgery,were selected to be eligible for the study.All patients were immobilized in treatment position by breast beard of Med-Tec 250.The motion of the breast treatment volume was observed on a fluoroscope in different directions under free breathing in 16 patients.The set-up errors in different dimensions during irradiation were measured by weekly portal films (PF) in comparison with digital reconstructed radiographs (DRR) in 11 patients.Results The central lung distance (CLD) variation during free breathing was (2.1?1.2) mm which is greater than the motion to- wards the other directions.By comparing the PF and DRR,the systemic error,random error and overall er- ror in the outer,inner and cranio-caudal directions was 1.9,1.6,2.5 and 2.4,1.7,3.1 and 2.6,2.3, 3.5 mm,respectively.In addition,the discrepancy of the treatment position in cranio-caudal direction and breast volume was most obvious at the beginning 2 weeks with the peak of breast volume at the second week. It decreased gradually during the following 3 weeks.Conclusions This study suggests that the mean value of the motion of the breast target volume during one breathing cycle is less than 2 mm.The set-up errors dur- ing irradiation is the greatest in cranio-caudal direction,suggesting that the fixing precision of the breast board should be further improved.The set-up error during irradiation are most obvious at the beginning two weeks,with the peak of the breast volume in the second week.

Objective: In order to describe the employment status of the first group of targeted admission medical graduates, evaluate the effects of targeted admission medical education program, find out the existing problems and provide relevant policy recommendations.Methods: This study conducted follow-up survey among 305 medical graduates and 315 clinical medical graduates in four medical colleges of the central and western regions.Data analyses of the contract fulfillment, their employment status, and their participation in the standardized residency training are carried out.Results: The contract fulfillment rate of rural-oriented medical graduates is 99.3%, while the percentages of rural-oriented medical graduates and clinical medical graduates are 90.7% and 2.8%, respectively.Their average monthly incomes are respectively 2,011 and 2,774 yuan, and their proportions of participating in standardized residency training are 77.8% and 43.3% respectively.From the findings it can be seen that the employment situation of the first group of targeted admission medical graduates in four medical colleges and universities is quite good, but the policy implementation process in terms of permanent post and income is less satisfactory.However, the way how medical graduates should participate in the standardized residency training is not yet clearly regulated.This paper recommends that medical colleges and universities should well coordinate with local health administrative departments and human resources and social security departments to systematically deploy medical graduates.At the same time, full consultations should be conducted to make appropriate arrangement for medical graduates to participate in standardized residency training.
