Objective To research the correlation on high performance liquid chromatography (HPLC) and antidepressant effect of different elution fractions of acorus tatarinowii schott macroporous resin .Methods Prepared different fractions by using AB‐8 macroporous resin .Establish HPLC characteristic chromatograms of crude drugs and different elution fractions from AB‐8 acorus tatarinowii schott macroporous resin by using gradient elusion .Confirm characteristic peaks in chromatograms .despair mod‐els of male mice ,including tails suspension test (TST ) ,forced swimming test (FST ) were used to evaluate antidepressant effects by taking orally .Results HPLC chromatograms of crude drugs and different fraction of acorus tatarinowii schott showed that they had same characteristic peaks .Elution of 90% and 70% alcohol solution from AB‐8 macroporous resin can obviously reduce TST and FST time .The anti‐depressant effect were associated with characteristic peaks on chromatogram .Conclusion Acorus tatarinowii schott has anti‐depressant effect ,and mainly from 70% and 90% alcohol solution eluted from AB‐8 macroporous resin .HPLC char‐acteristic chromatography and data relationship between relative peaks can be used to judge the antidepressant effects of acorus ta‐tarinowii schott ,and give reference to research and product development .

Objective:To describe the treatment of the first carpometacarpal arthritis in Eaton Ⅱ, Ⅲ combining the hemi excision of trapezium with tendon ball and evaluate its clinical efficacy.Methods:Data of patients with the first carpometacarpal arthritis who were treated by hemi excision of trapezium and tamponade of the tendon ball from March 2013 to October 2018 were retrospectively analyzed. Twelve patients were all females with an average age of 55±2.8 years (range, 48-61 years). There were 3 cases of left thumbs and 9 cases of right. The study was only researched with primary osteoarthritis patients, preoperative imaging Eaton stages, including 8 cases inⅡstage, 4 cases in Ⅲ stage. Postoperative X-ray examination was performed, and the subsidence rate of the first metacarpal bone was evaluated according to height of arthroplasty. Preoperative and postoperative pain was evaluated according to visual analogue scales (VAS) score and DASH score. Preoperative and postoperative finger movement was evaluated according to the changes in preoperative and postoperative grip and pinch force.Results:The average follow-up period was 12±4.8 months (range, 6-17 months). The mean score of VAS after operation was 1.2±1.0 which was lower than 6.3±1.5 before operation ( t=13.4, P=0.0001); DASH score after operation was 26.2±9.6 which was lower than 48.9±13.0 before operation ( t=5.7, P=0.0001); Grip force after operation was 25.5±6.8 kg which was higher than 15.0±2.9 kg before operation ( t=7.3, P=0.0001); Pinch force after operation was 3.2±0.8 kg which was higher than 2.1±0.4 kg before operation ( t=3.6, P=0.0045), and all of these four above data has statistic difference. At the latest postoperative follow-up, the height index of arthroplasty was 0.299±0.022, and there was no significant change ( F=1.337, P=0.276) when compared with 0.306±0.021 before surgery and 0.313±0.024 after surgery. After the operation, 2 patients presented with incision redness and swelling and exudation. It was considered that local hematoma in the intra-articular operation could not be completely absorbed. After several dressing changes, the redness and swelling subsided and the exudation was controlled. Conclusion:Preserving the proximal joint surface of trapezium and tamponading tendon ball, could reduce the subsidence rate of the first metacarpal bone and alleviate the pain of the first carpometacarpal joint, thus may effectively improve the joint function. It has a significant effect on the treatment of Eaton Ⅱ,Ⅲ stage of the first carpometacarpal arthritis.
