Objective To design and synthesize derivatives of oleanolic acid and ursolic acid, and investigate their anti-hepatitis C virus （HCV） activity along with that of common triterpenoid acids. To explore the structure-activity relationship and provide a reference for the research of anti-HCV drugs derived from natural products through obtaining compounds with higher activity. Methods Oleanolic acid and ursolic acid were directly reacted with corresponding amines using PyBOP as a condensing agent in the presence of DIEA. Alternatively, the target compounds were prepared through PCC oxidation followed by the Baeyer-Villiger reaction catalyzed by m-CPBA. In vitro anti-HCV activity was tested using the HCVcc infection model. Molecular docking was performed by Autodock software to investigate the interaction between the active compounds and HCV NS5B. Results Oleanolic acid, glycyrrhetinic acid, ursolic acid, and asiatic acid all exhibited certain anti-HCV effects. Specifically, oleanolic acid derivatives OA2-OA4, OA6, and OA7, as well as ursolic acid derivatives UA1 and UA2, demonstrated superior anti-HCV activity compared to their parent compounds. Preliminary structure-activity relationship analysis revealed that introducing a bulky group to 28-COOH of oleanolic acid and ursolic acid enhanced their activity. Molecular docking results demonstrated that the active compounds could stably bind to HCV NS5B, thereby exhibiting antiviral activity. Conclusion Pentacyclic triterpenoids possessed anti-HCV effects, and their derivatives coud be synthesized to obtain more active compounds. The anti-HCV mechanism of these compounds may be associated with their inhibition of NS5B.

Objective:To analyze the clinic effects of arthroscopic partial trapeziectomy and suture button suspensionplasty in the treatment of first carpometacarpal joint (CMCJ) Eaton stage II/III arthrosis.Methods:A retrospective study was conducted on a total of 15 cases (16 hands) of patients including 5 males (1 bilateral) and 10 females with CMCJ stage II/III arthrosis who underwent surgical treatment at the first affiliated hospital of Shenzhen university from January 2020 to June 2022, with mean age of 56.7±6.4 years (range, 46-75 years). The duration from pain to treatment was 7.8±3.2 months (range, 4-14 months). X-ray showed narrowing of CMCJ with osteophytes and distal radial subluxation. All the patients were treated with arthroscopic partial trapeziectomy and suture button suspensionplasty. The preoperative and last postoperative follow-up radiographs, visual analogue scale (VAS), thumb's Kapandji scores, disabilies of the arm, shoulder, and hand (DASH) scores, grip and pinch strength and time to return to work were compared.Results:All cases were followed up for 19.6±6.3 months (range, 11-36 months). The postoperative X-ray showed all the CMCJs were reduced with a normal height of first metacarpal. The mean time for patients to return to their daily activities was 18.69±3.70 d and the mean time to return to work was 24.63±4.91 d. The average VAS score decreased from 6.56±1.15 preoperatively to 1.00 (0.75, 1.25). The preoperative Kapandji's score was 8.00±0.82 and the postoperative Kapandji's score was 8.00 (7.25, 9.00). The average DASH values improved from 24.06±3.19 to 4.00 (3.00, 5.00). The were significant differences except for Kapandji score ( Z=-4.905, P<0.001; Z=-0.121, P=0.905; Z=-4.846, P<0.001). The mean grip and pinch strength showed improvement from an average of 16.4 (14.13, 18.68) kg and 1.70±0.35 kg to 26.14±3.27 kg and 3.58±0.91 kg with significant difference ( Z=-4.617, P<0.001; t=-7.669, P<0.001). Conclusion:Arthroscopic partial trapeziectomy and suture button suspensionplasty is a minimally invasive surgery for the treatment of first CMCJ Eaton stage II/III arthrosis. By this technique, the patients' existing instability and pain problems can be solved.

Objective:It sorts out the relevant policies of China's public hospital salary system reform,summarizes the short-comings of public hospital salary policy in the process of formulation,and provides references for the subsequent adjustment and opti-mization of salary system.Methods:Based on Policy Modeling Consistency(PMC)index model,public hospital salary policies were collected and preprocessed,high-frequency words were extracted by text mining method,and an evaluation index system of sal-ary policies of public hospitals was constructed.By calculating the score of PMC index and first-level variables,the common prob-lems of various policies are analyzed,and specific suggestions were put forward.Results:The average PMC index of 12 public hos-pital compensation policies was 6.00,the overall quality of the policies was good,but there was still much room for improvement.The main common problems are the lack of internal and external linkage,the neglect of the incentive function of non-economic com-pensation and the unreasonable compensation structure.Conclusion:From the perspective of policy,the reform of public hospital salary system is a systematic project.It is suggested to take holistic thinking as the guide in the follow-up policy making process,en-hance the internal and extemal coordination of the policy,attach importance to the incentive role of non-economic compensation and optimize the salary structure,so as to promote the steady operation of the salary system reform of public hospitals.
