OBJECTIVETo study the synergistic effects of electroacupuncture on the treatment of knee osteoarthritis after arthroscopic debridement.

METHODSFrom May 2008 to July 2010, 78 patients with knee osteoarthritis were randomly divided into two groups. There were 42 patients in the experimental group, including 16 males and 26 females, ranging in age from 41 to 63 years, with an average of (53.62 +/- 6.53) years; the disease course ranged from 8 to 24 months, with an average of (10.35 +/- 6.42) months. The patients were treated with arthroscopic debridement combined with electroacupuncture after operation. There were 36 patients in the control group, including 14 males and 22 females, ranging in age from 40 to 62 years, with an average of (54.34 +/- 7.67) years; the disease course ranged from 6 to 25 months, with an average of (11.94 +/- 5.13) months. Those patients were treated only with arthroscopic debridment. All the patients performed isometric quadriceps femoris contraction exercise and knee flexion and extension activities after operation. The visual analog scale(VAS) score and Lysholm knee score were used to evaluate the therapeutic effects.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 30 months, with an average of 15.6 months. At the final follow-up, VAS score was significantly decreased, and the Lysholm score, except for the item demanding for support, significantly increased, compared with those before surgery respectively in both groups. There was significant difference in VAS score between two groups after treatment. As to Lysholm score, there were significant differences in limp, pain, swelling, stair activity and squat, but there were no significant differences in items of interlocking and instability between two groups after treatment.

CONCLUSIONElectroacupuncture can effectively improve the clinical symptoms and knee joint's motor function of knee joints in patients with knee osteoarthritis, as well as the synergistic effects on the treatment of knee osteoarthritis after arthroscopic debridement, leading to a much better long-term therapeutic effect with respect of improving the function of knee joint. This therapy, combined with traditional Chinese medicine and Western Medicine,is worth of clinical application in the treatment of knee osteoarthritis.

OBJECTIVE:To explore effective pharmaceutical administration measures for the rational adjunctive drugs. METH-ODS:The effective pharmaceutical administration of adjunctive drugs in medical institutions of Sichuan province was introduced, including establishing key monitoring management system of adjunctive drugs (establishing and implementing prescription review system,rational drug use training,strict supervision and examination) and playing promotion effect of provincial pharmaceutical quality management control center on medical institutions,etc. The effects of pharmaceutical administration in 18 third-grade class-A medical institutions were evaluated through statistically analyzing rational utilization ratio,drug ratio,consumption sum of ad-junctive drugs. RESULTS:Up to May 2016,key monitoring management system of hospital adjunctive drugs had been established and improved in medical institutions over Sichuan province. The rational utilization ratio of adjunctive drugs in 18 medical institu-tions increased from 69.41% in Jan. 2016 to 79.05% in May 2016;drug ratio decreased from 29.22% to 27.93%. The monthly consumption sum of adjunctive drugs decreased from 22 970 000 yuan in Apr. 2015 to 17 380 000 yuan in Apr. 2016(decreasing by 20.49%). CONCLUSIONS:Medical institutions of Sichuan province conduct effective pharmaceutical administration of adjunc-tive drugs through establishing the key monitoring management system for medical institutions and playing the role of the provincial pharmaceutical quality management control center for the supervision.

AIM: To investigate whether carnosine can inhibit cataract formation and protect Na+-K+ATPase against inactivation induced by a glucocorticoid.METHODS: Two hundred and twenty clear lenses cultured in vitro were randomly divided into five groups: control group (DMEM), steroid group (DMEM+Dexamethason 10μmol/L),lower concentration carnosine-treated group (DMEM+Dexamethason 10μ mol/L+Carnosine 2mmol/L), higher concentration carnosine-treated group (DMEM+Dexamethason 10μmol /L+Carnosine 5mmol/L) and carnosine group (DMEM + Carnosine 5mmol/L). Progression of cataract formation was evaluated daily using a dissecting microscope. On 1, 3, 5 and 7d, 10lenses of every group were homogenized and the activity of Na+-K+ATPase was measured by using spectrophotometer.RESULTS: During the incubation, mistlike opacity was observed in the lenses of the control group and carnosine group,but in the steroid group appeared dense nuclear opacity, while both two carnosine-treated groups came out visible demarcation between nuclear and cortical regions on 7d. A decrease in the activity of Na+-K+ATPase was found in the lens of the steroid group. On 3, 5, 7d, Na+-K+ATPase activity decreased 22.34% (P=0.002),47.98% (P＜0.001),75.37% (P＜0.001) compared with that at 1d, respectively. In the carnosine group,the activity of Na+-K+ATPase remained at the level of the control throughout the 7-d incubation, indicating that carnosine itself did not interfere with the original lens enzyme activity. In the lower concentration carnosine-treated group, on 3, 5, 7d,the activity of Na+-K+ATPase increased 10.8% (P＜0.05),44.6% (P＜0.01), 57.4% (P＜0.01) of control activity, respectively. In the higher concentration carnosine-treated group, on 3, 5, 7d, the activity of Na+-K+ATPase increased 11.3% (P＜0.05), 45.7% (P＜0.01), 57.6% (P＜0.01) of control activity,respectively. The activity of Na+-K+ATPase in both two carnosine-treated groups were only 6.7% and 6.5% lower than that of the control group after 7-d incubation. After the 7-d incubation, the Na+-K+ATPase activity of the lenses in the steroid group decreased significantly compared with carnosine-treated groups (P＜0.01).CONCLUSION: Carnosine prevents the cataract formation induced by a glucocorticoid, and significantly inhibits the inactivation of Na+-K+ATPase induced by a glucocorticoid.
