ABSTRACT
Objective To analyze the effect of Yaotongning capsule in the treatment of lumbar osteoarthritis patients.Methods From March 2013 to March 2015 in our hospital, 80 cases of lumbar osteoarthritis patients according to the digital table method were divided into two groups: the control group and the experimental group.The patients of the control group were given Bitongning, and the patients of the experimental group were given Yaotongning capsule, and the therapeutic effect, serum indexes and Japanese Orthopaedic Association ( JOA ) of two groups were compared. Results The curative effect of the experimental group was higher than control group(95.00%vs.67.50%) , the JOA score of the experimental group was higher than control group [(27.46 ±1.07)points vs.(21.06 ±1.89)points] (P<0.05).After treatment, the MMP-3(65.28 ±4.37) ng/L and IL-1β(12.43 ±1.01) ng/L of the experimental group were significantly lower than MMP-3(79.56 ±5.36) ng/L, IL-1β(16.44 ±1.03) ng/L of the control group, and the difference was significant (P<0.05).Conclusion The lumbar osteoarthritis patients with Yaotongning capsule has obvious effect, and the function of lumbar intervertebral joint improves obviously, and the serum index is normal, safe and reliable.
ABSTRACT
Objective To optimize the prescription matrix proportion of Bitongning Patch and observe its percutaneous absorption in vitro. Methods U6(66) Uniform design was performed to investigate the influence of scopolamine and aconitine in the proportion for 24 h cumulative permeation in vitro. The drug permeation behavior through excised mouse skin was studied with improved Franz diffusion cell. Results With the matrix ratio for PVA: 11.02%, PVP: 29.93%, glyceroh 7.42%, azone: 4.95%, and propanediol: 11.06%, respectively, the Patch had the maximal cumulative permeation amount and cumulative permeation curve coincided with the Higuchi Equation. Conclusion The prescription composition optimized by uniform design meets the requirement of skeleton-controlled transdermal delivery system.
ABSTRACT
AIM: To prepare Bitongning Patch(Flos Daturae, Moschus and Camphora, etc.) and study its in vitro release characteristics. METHODS: Bitongning Patch was prepared with high polymer hydrophilic material as matrix. The determination method of scopolamine was established by HPCE. The in vitro release was studied according to the requirement of Chinese Pharmacopoeia(2000) and the percutaneous absorption of Bitongning Patch was evaluated in use of the Franz diffusion cell. RESULTS: The release mechanism of Bitongning Patch in vitro coincided with Higuchi Equation. The release rate was 0.4698mg?cm -2?h -1/2. Scopolamine in Patch permeated in vitro at the speed of 0.067mg?cm -2?h -1 by zero-order kinetics. CONCLUSIONS: Bitongning Patch is a skeleton controlled TDDS whose permeation speed is limited by skin.
