1.The effects of Metacycloprodigiosin on tumor metastasis-associated cell behavior in vitro
Chinese Pharmacological Bulletin 2010;26(4):501-505
Aim To investigate the effects of Metacycloprodigiosin(MP) on tumor metastasis-associated cell behavior in vitro.Methods The effects of MP on the proliferation of HUVEC and 4TO7 cells were observed by MTT assay.Migration abilities of HUVEC and 4TO7 cells were measured by wound healing assay.Tube formation of HUVEC in the presence of MP for 10 hours was evaluated on matrigel basement membrane matrix.The abilities of adhesion and invasion of 4TO7 with MP for 24 hours were measured quantitatively by cell adhesion and transwell assay.Results MP did not affect proliferation of HUVEC and 4TO7 cells in concentration less than 10 μmol·L-1.MP inhibited HUVEC cells migration and formation of the tube in the concentrations of 0.01 to 1 μmol·L-1.In these concentrations MP could also inhibit 4TO7 cells migration,adhesion and invasion.Conclusion sThese results demonstrate that MP effectively inhibits tumor metastasis in vitro.All these findings suggest its potential as an anti-tumor metastasis compound in vivo.
2.Challenges from the drug zero price margin policy and recommendations
Chinese Journal of Hospital Administration 2013;(1):1-6
Investigations and interviews on six county (city)-level public hospitals practicing the drug zero price margin policy discovered increases on average outpatient expense per visit,average outpatient drug expense per visit,ratio of outpatient drug expense,average drug expense per hospital discharge,and ratio of drug expense upon discharge as well as the total ratio of drug expenses.An analysis of the poor performance of the policy results in the following recommendations.A better performance of this policy calls for support of such reforms as drug supply manner,drug price control,doctors' incentives for over-prescription and payment manner at public hospitals.Only with these support can this policy reach its expected outcomes of alleviating the drug expense burden of the people.
3.Optimization of Processing Technology for Atractylodes lancea Stir-baking with Bran by Box-behnken Re-sponse Surface Methodology
China Pharmacy 2015;(34):4844-4846
OBJECTIVE:To optimize the processing technology for Atractylodes lancea stir-baking with bran. METHODS:Us-ing the content of atractylodin,yield of water-soluble extract and ethanol-soluble extract,appearance score as comprehensive in-dex,the effects of excipient amount,stir-baking time and temperature on the quality of A. lancea stir-baking with bran were investi-gated by Box-behnken design-response surface method,so as to optimize the processing technology parameters of A. lancea stir-bak-ing with bran,and verification test were conducted. RESULTS:The optimized parameters were that the excipients amount was 10% medicinal material,stir-baking at 140 ℃ for 3 min;average comprehensive score of verification test was 0.39 (RSD=2.88%,n=3),which was close to predicted value 0.38. CONCLUSIONS:Box-behnken response surface method is reasonable and feasible for the optimization of the processing technology for A. lancea stir-baking with bran.
4.Changes of serum thyroid hormone levels in patients with polycystic ovary syndrome induced by ovulation disorder
Clinical Medicine of China 2015;31(6):514-516
Objective To analyze the relationship and significance between plasma level of thyroid hormone and ovulation disorder of (polycystic ovary syndrome)PCOS.Methods Eighty-nine cases with PCOS were induced ovulation by CC+HCG.During menstrual cycle of induced ovulation,PCOS patients were divided into two groups according to Ovulation (No ovulation 40,ovulation 49).The level of thyroid hormone at different follicular development period and ovulatory time were detected.Result Levels of thyroid hormone at two groups were no difference at 5 mm,10 mm,15 mm size follicular phase(P>0.05).But there was significant at follicular 20mm size(F inner groups=4.38,50.34,48.65;P<0.05).The level of T3 an T4 at No ovulation group was lower than those in ovulation group(T3:(2.69±0.15) nmol/L vs.(1.97±0.17) nmol/L;T4:(124.38±0.29) nmol/L vs.(97.43±0.16) nmol/L).The level of TSH at No ovulation group was (3.43±0.10) mU/L,higher than that in ovulation group ((1.38 ± 0.18) mU/L;P < 0.05).Conclusion The level of thyroid hormone in patients of ovulation group is at a normal level when the follicle is mature,and the level of thyroid hormone can affect the normal ovulation of patients with PCOS.
5.Therapeutic effect of heat-sensitive moxibustion plus medications for senile osteoporosis and its effect on serum BMP-2 and OPG levels
Journal of Acupuncture and Tuina Science 2020;18(3):213-218
Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus medications on senile osteoporosis (SOP), and to explore the related mechanisms. Methods: A total of 70 elderly participants with osteoporosis were randomly divided into an observation group and control group, with 35 cases in each group. The control group was treated with conventional drugs, and the observation group was treated with heat-sensitive moxibustion on the basis of the conventional drugs. Both groups were treated for 3 months. Before and after treatment, assessed the visual analog scale (VAS) and Oswestry disability index (ODI) scores, determined the bone mineral density of the participants' lumbar spine (L2-L4) and left femoral neck, and detected the participants' serum bone morphogenetic protein-2 (BMP-2) and osteoprotegerin (OPG) levels. Results: After treatment, the VAS scores of both groups were lower than before treatment (both P<0.05), and the VAS score of the observation group was significantly lower than that of the control group (P<0.05). After treatment, the bone mineral density values of the lumbar spine and left femoral neck in both groups were significantly higher than before treatment (both P<0.05), and the bone mineral density values of the observation group were higher than those of the control group (P<0.05). After treatment, the ODI scores of the two groups were lower than those before treatment (both P<0.05), and the ODI score of the observation group was lower than that of the control group (P<0.05). After treatment, the serum BMP-2 and OPG levels in the observation group were significantly higher than those in the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus medications for SOP can significantly relieve patients' pain, improve dysfunction, and increase bone density, which may be related to the improvement of the serum BMP-2 and OPG levels.
