Objective:This paper aims to analyze the related effects of the low price medicine policy, and prob-lems in the implementation process. Methods:To retrieve an official website of the state food and medicine supervi-sion and administration, collect the package supplements of the low-price medicines and analyze their varieties according to their situations, and calculate he highest and lowest average daily use indicators for the medicine, etc. from January 2009 to August 2014. Results:(1) The low-price medicine list contains 533 kinds of standard medi-cines, and the coincidence rate with the essential medicines list is 51. 59%. Results also show that 96. 82% of the low-price medicines are incorporated into the national medical insurance directory. ( 2 ) The daily medicine cost difference of the maximum and minimum bidder price to the same medicine produced by different manufacturers ran-ges from 0. 01 to 30. 96 Yuan with 94. 76% of the western medicine dosage constituting the existing price rise space. (3) The daily medicine cost difference ranges from 0. 01 to 19. 35 Yuan with 92. 13% of the proprietary Chinese medicine varieties constituting the existing price rise space. Discussions:The low-price medicine varieties lack in the strict proof, the fact of low pricing the medicine has a two-way effect, and the connection between the low-price medi-cine administration policy and other policies is unclear.

Objective Wnt signaling plays an important role in the development and progression of renal cell carcinoma (RCC).This study aimed to evaluate the effects of the Wnt signaling inhibitor 15-oxospiramilactone on the proliferation , migration, cell apoptosis, and cycles of the human RCC cell line 786-0, and to investigate the possible mechanisms of this small molecule acting on RCC in ivtro. Methods We treated 786-0 cells with DMSO ( blank control group ) and 15-oxospiramilactone at the concentrations of1.25μmol/L (low 15 -OSL), 2.5μmol/L (medium 15-OSL), and 5μmol/L (high 15-OSL), respectively, for 72 hours.Then we observed the changes in the proliferation and migration of the 786-0 cells by MTT and scratch-wound assay and determined their apopto-sis and cycles by Annexin V-FITC/PI assay and flow cytometry . Results 15-oxospiramilactone significantly inhibited the growth of the 7860-cells, with the IC 50of 1.088 μmol/L at 72 hours, and decreased their migration distance (P<0.05).After 36 hours of treatment, the apoptosis rates of the 786-0 cells in the low, medium, and high 15-OSL groups were (12.17 ±0.56), (18.54 ± 1.07), and (50.74 ±1.28) %, respectively, significantly increased as compared with (7.85 ±0.42) %in the blank control group (P<0.05), and in an obviously concentration-dependent manner.15-oxospiramilactone remarkably reduced the number of cells in the G0/G1 phase and increased that in the G 2/M phase (P<0.05). Conclusion 15-oxospiramilactone can significantly inhibit the pro -liferation and migration and induce the apoptosis of 786-0cells in vitro.It may be a potential anti-RCC agent.

Objective A three-dimensional (3D) printing precise pressure device was designed specifically targeted at cambered limbs according to the requirement of postoperative rehabilitation of total knee replacement(TKR), and its effectiveness and safety was verified by finite element analysis. Methods Based on gastrocnemius muscle of lower limbs as the pressurized objects, the precise pressure device was designed, which contained an air pressure generating module, an inflatable airbag and a 3D printing brace. Through the closed loop control algorithm, the device stably supplied different pressures in the airbag. Distributed pressure data of the airbag-skin within contact surface were collected under different experimental conditions and imported into biomechanical simulation software which combined CT images to reconstruct 3D model of the lower limb mechanics. Finally, the effective compression area fraction and the joint micro-motion angle under each condition were obtained, to verify the effectiveness and safety of the system. Results Using generally preferred 4 cm-size offset and 4-barrel airbag configurations, under different intracapsular pressure of 5.32,6.65,7.98,9.31,10.64 kPa, the simulated knee joint micro-motion angles were 5.3°, 6.1°, 7.2°, 9.5°, 10.6°, respectively, and the effective compression area fraction could be up to 90-8%-95-2%. Conclusions For the optimized scheme, the dynamic range of joint micro-motion angle and the effective compression area fraction caused by different airbag pressure values were the best and met the design requirements of effectiveness and safety. The research findings can contribute to analyzing the influence of compression system on limb biomechanics, which are of great significance for effective and safe rehabilitation training after TKR.

OBJECTIVE To provide a reference for the definition of the legal attributes of the provincial Chinese herbal pieces processing norms and the improvement of legal expression for the drug standards in Drug Administration Law. METHODS Based on the legal evolution of local drug standards in China, the composition of national drug standards for Chinese herbal pieces and the composition of current provincial Chinese herbal pieces processing norms were analyzed; at the same time, based on the method of legal interpretation, the legal connotation of the provincial Chinese herbal medicine processing norms in Drug Administration Law was investigated. RESULTS & CONCLUSIONS In the practice of drug supervision, the provincial Chinese herbal pieces processing norms are essentially local drug standards. The newly revised Drug Administration Law defines the drug standards specifically, but does not stipulate the legal attribute of drug standards for the provincial Chinese herbal pieces processing norms, and there are certain legislative technical defects. It is suggested that when amending the Drug Administration Law, the legal attributes of the drug standards of the provincial Chinese herbal medicine processing norms should be clarified.
