Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.

OBJECTIVE: To develop an automated chimeric analysis and reporting platform based on short tandem repeat (STR) and capillary electrophoresis methods for allogeneic hematopoietic stem cell transplantation (allo-HSCT) so as to improve work efficiency. METHODS: Apache, MySQL, PHP and HTML5 were used to build the database and interface. The STR locus geno typing and chimeric analysis logic and flow were set up on the basis of STR rules and capillary electrophoresis. STR genotyping and 194 times of chimeric testing data of 100 patients after allo-HSCT were used to test the platform for automatic STR locus genotyping, chimeric calculation and report generation. RESULTS: The established platform could realize the functions of STR locus customization, STR genotype determination, automatic chimeric analysis, and detection information database management, which can automatically generate an integrated report including multiple sequential chimeric results and trend graphs for the same patient and can be accessed and used simultaneously by different users through different browser interfaces. The results of automated analysis by the platform are completely consistent with that of manual analysis by experienced technicians, and the possibility of manual analysis error is reduced through automation. The time required for automatic analysis using this platform is approximately 1/6-1/5 of manual analysis. CONCLUSION The automatic analysis platform built in this study is operation stable and reliable in analysis results, which can improve work efficiency and report connotation, thus worthing popularized and applicable.

OBJECTIVETo explore the therapeutic effect of Yishen Qufeng Shengshi Recipe (, YQSR) in patients with glomerular proteinuria METHODS: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group (108 cases) and the control group (37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR (200 mL, twice per day, orally) and losartan (50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment.

RESULTSAt the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6% (84/103), 87.4% (90/103), and 92.2% (95/103), respectively, in the treatment group and 47.2% (17/36), 55.6% (20/36), and 61.1% (22/36), respectively, in the control group, with significant difference between the two groups (P<0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months (P<0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group (P<0.05 or P<0.01, respectively) CONCLUSION: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.

Objective To observe the current status of secondary prevention medication usage and their relation with on-treatment platelet reactivity in patients with Acute Coronary Syndrome(ACS) treated with aspirin and clopidogrel. Methods A total of 176 patients hospitalized from 2014 to 2015 due to ACS in the Department of Cardiology, Peking University People's Hospital were enrolled and on-treatment platelet reactivity was tested by thromboelastography(TEG)and CYP2C19*2,*3 and*17 alleles were analysed. Details of secondary prevention medication and patients' clinical characteristics were recorded. The relation of secondary prevention medication and on-treatment platelet reactivity was analyzed by multi-logistic regression after adjusting for CYP2C19 alleles and clinical characteristics covariates.Results A 94.89% of patients was treated with statins while 80.68% with beta blocker. The platelet inhibition rate were (45.33±28.78)% and the high on-treatment platelet reactivity (HTPR) rate tested by TEG was 37.50%. In the multivariate logistic regression analysis, usage of β-blockers during hospitalization as well as phenotypes of CYP2C19*2,*3 and *17,clinical presentation with ST-segment elevation myocardial infarction and the length of stents were associated with HTPR defi ned by TEG. The percentage of HTPR rate was signifi cantly lower in patients treated with than those without β-blockers (72.73% vs. 85.45%,OR 0.18,95%CI 0.06-0.53,P=0.002)after adjusting genetic factors and other covariates.Conclusions There was a signifi cant correlation between beta blockers usage and high clopidogrel on-treatment platelet reactivity.

OBJECTIVE: To observe the rehabilitation effect of non-invasive positive pressure ventilation( NPPV) in treating pneumoconiosis patients with pulmonary dyspnea. METHODS: A retrospective analysis was used to analyze the treatment compliance,treatment time,treatment effect and adverse reactions of 295 pneumoconiosis patients who had undergone inpatient NPPV treatment. RESULTS: The median of NPPV treatment time of 295 pneumoconiosis patients was 14( 1-281)days. The treatment compliance rate was 79. 66 %( 235 /295). The dyspnea improvement rate was 73. 22 %( 216 /295).The Chi-square test results showed that the dyspnea improvement rate increased with the prolonged treatment time( P <0. 01).

BACKGROUNDAccurate assessment of intra- as well as extra-cardiac malformations and radiation dosage concerns are especially crucial to infants and children with interrupted aortic arch (IAA). The purpose of this study is to investigate the value of prospective electrocardiogram (ECG)-triggered dual-source computed tomography (DSCT) angiography with low-dosage techniques in the diagnosis of IAA.

METHODSThirteen patients with suspected IAA underwent prospective ECG-triggered DSCT scan and transthoracic echocardiography (TTE). Surgery was performed on all the patients. A five-point scale was used to assess image quality. The diagnostic accuracy of DSCT angiography and TTE was compared with the surgical findings as the reference standard. A nonparametric Chi-square test was used for comparative analysis. P <0.05 was considered as a significant difference. The mean effective radiation dose (ED) was calculated.

RESULTSDiagnostic DSCT images were obtained for all the patients. Thirteen IAA cases with 60 separate cardiovascular anomalies were confirmed by surgical findings. The diagnostic accuracy of TTE and DSCT for total cardiovascular malformations was 93.7% and 97.9% (P > 0.05), and that for extra-cardiac vascular malformations was 92.3% and 99.0% (P < 0.05), respectively. The mean score of image quality was 3.77 ± 0.83. The mean ED was 0.30 ± 0.04 mSv (range from 0.23 mSv to 0.39 mSv).

CONCLUSIONSIn infants and children with IAA, prospective ECG-triggered DSCT with low radiation exposure and high diagnostic efficiency has higher accuracy compared to TTE in detection of extra-cardiac vascular anomalies.

OBJECTIVETo observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS).

METHODSTotally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups.

RESULTSCompared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01).

CONCLUSIONYQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.

Abstract： Objective To study the influence from different placement angles of acetabular component on inner and outer stress distributions of periacetabulum in acetabular reconstruction of total hip arthroplasty (THA), so as to explore proper orientation for improving stability of acetabular component after THA. Methods Based on model with inhomogeneous material property assignment, nine THA models with acetabular component at different anteversion angles(15°, 20°, 25°) and abduction angles(40°, 45°, 50°) as well as one normal hip model were constructed. The maximal hip contact force in phase of single leg stance during normal gait cycle was chosen as the loading condition. In addition, according to the qualitative and quantitative principle, inner and outer stress distributions on 9 THA models were analyzed and compared with the normal hip model as control. Results When abduction angle of acetabular component was the nearest to anatomic angle (19° anteversion, 46° abduction) of acetabulum, the phenomenon of stress shielding on periacetabulum was the most obvious. When abduction angle of acetabular component was placed at 45° and anteversion angle changed from 15° to 25°, no significant influence was exerted on the whole stress distributions of THA models. Meanwhile, when anteversion angle of acetabular component was 15°, the THA model had good stability in stress distributions, and the phenomenon of stress shielding on cortical and cancellous bone was obviously improved. Conclusions For patients who have normal anatomic acetabulum and need to be treated with THA, the abduction angle of acetabular component should be placed at 45°, as that of normal acetabulum; the anteversion angle should be 5° smaller than that of normal acetabulum and between 15° and 20°.
