Objective:To analyze the efficacy and safety of curcumin in the treatment of knee osteoarthritis.Methods:The randomized controlled trials of curcumin in the treatment of knee osteoarthritis published from January 2011 to August 2021 were retrieved. The bias risk of the included literatures was evaluated by Revman 5.3 software, and the efficacy related indexes and the incidence of adverse events were analyzed by Stata 16.0 software. The weighted mean difference ( WMD) was calculated for the difference of efficacy indexes, the odds ratio ( OR) was calculated for the difference of safety indexes, the difference was compared by t test. Results:① A total of 9 relevant literatures were included, all of which were in English. ② A total of 724 patients were included in the study, of which 383 were treated with curcumin capsules and 341 were treated with placebo. ③ The visual analogue scale/score (VAS) of patients treated with oral curcumin at 3-4, 6 and 8 weeks were significantly lower than those of patients treated with oral placebo, the differences were statistically significant [weighted mean difference ( WMD)=-1.09, 95% CI (-1.44, -0.73), P<0.001; WMD=-1.52, 95% CI (-2.35, -0.69), P<0.001; WMD=-1.20, 95% CI(-1.71, -0.69), P<0.001]. ④ The western Ontario and McMaster universities osteoarthritis index (WOMAC) scores of patients treated with oral curcumin for 3-4 and 6-8 weeks were significantly lower than those of patients treated with oral placebo, and the differences were statistically significant [ WMD=-7.96, 95% CI(-14.89, -1.04), P=0.020; WMD=-15.34, 95% CI(-20.51, -10.18), P<0.001]. Specifically, the WOMAC pain and stiffness scores of patients treated with oral curcumin for 6-8 weeks were significantly lower than those of patients treated with oral placebo, and the differences were statistically significant [ WMD=-2.16, 95% CI(-3.69, -0.63), P=0.010; WMD=-1.00, 95% CI (-1.54, -0.46), P<0.001]. The WOMAC joint function scores of patients treated with oral curcumin for 3-4 and 6-8 weeks were significantly lower than those of patients treated with oral placebo, the difference was statistically significant [ WMD=-3.21, 95% CI(-4.51, -1.92), P<0.001; WMD=-7.07, 95% CI(-11.19, -2.94), P<0.001]. ⑤ There was no significant difference in the incidence of adverse events between oral curcumin and placebo [ OR=1.19, 95% P(0.74, 1.90), P=0.478]. Conclusion:Compared with placebo, oral curcumin can significantly alleviate the pain, stiffness and joint function of patients with knee osteoarthritis, and its safety is similar to placebo.

A simple and rapid immunochromatographic test strip incorporating a colloidal gold-labeled recombinant Nsp7 antigen probe was successfully developed for the detection of anti-porcine reproductive and respiratory syndrome virus (PRRSV) antibodies in swine. Recombinant Nsp7 protein of PRRSV labeled with colloidal gold was dispensed on a conjugate pad for use as the detector. Staphylococcal protein A and purified porcine anti-Nsp7 antibodies were blotted on a nitrocellulose membrane to form test and control lines, respectively. A comparison of the strip with standard diagnostic tests, enzyme-linked immunosorbent assays and immunoperoxidase monolayer assay, was also performed. The immunochromatographic test strip was shown to be of high specificity and sensitivity. Furthermore, the strip assay is rapid and easy to perform with no requirement for professional-level skills or equipment. It is suggested that the immunochromatographic test strip can be used to quickly and accurately detect PRRSV antibody and to be suitable for diagnostic purposes in the field.

Objective:
To explore the therapeutic value of interventional methods for hemorrhage caused by mandibular arteriovenous malformations.
Methods:
The clinical data of 7 patients (3 males and 4 females) with mandibular arteriovenous malformations treated by interventional therapy from January 2012 to January 2018 in the First Affiliated Hospital, Zhengzhou University were retrospectively analyzed. Of all patients, 4 patients suffered from sudden massive hemorrhage and 3 patients suffered from spontaneous repeated bleeding. The age ranged from 8.0 to 13.0 (10.6±1.7) years. Of the 7 patients, 3 underwent interventional embolization via arteries and veins, and 4 underwent embolization only via arteries. The embolic materials were polyvinyl alcohol granules and coils. The follow-up period was 9—18 months and the curative effect was observed.
Results:
Among the 7 patients, 4 cases of acute massive hemorrhage were effectively controlled after interventional operation, 3 cases of chronic bleeding disappeared after interventional operation. No recurrence of bleeding occurred during the follow-up period, only 1 patient presented with oral infection and gingival swelling and hyperplasia. The symptoms were effectively controlled after anti-infection and debridement. No severe complications occurred in all patients.
Conclusion
Interventional therapy for ateriovenous malformation with hemorrhage is effective, safe and feasible, which is worthy of clinical application.

Objective To investigate the safety and feasibility of the interventional therapy on hemobilia induced by hepatic artery pseudoaneurysm(PsAn).Methods The clinical data of 28 patients with hemobilia in our department was analyzed retrospectively.All the patients were firstly treated with internal medicine,and then treated by interventional therapy.The angiography clearly displayed the shape,size and location of the PsAn,and superselective embolism was performed during the operation.The symptomatic treatment and the bile duct drainage were performed after operation.Postoperative follow-up time was 1-3 6 months,and the follow-up endpoint was the death of patient.Results 28 patients were diagnosed as hepatic artery PsAn.The interventional embolization therapy on hemobilia was completely effective.A total of 110 spring coils were applicated in the study,there was no complication related to interventional therapy.One patient with hilar cholangiocarcinoma was dead due to infection and liver failure after four weeks of operation.Two patients with choledochal carcinoma died of tumor progression after 11.5 and 14.2 months of interventional therapy,respectively.In addition,2 patients with gastric carcinoma died of tumor progression after 4 and 6.5 months of operation,respectively,and 1 patient with common bile duct stones who underwent laparoscopic surgery died of complications of coronary heart disease after 5 months of interventional therapy. The other patients all had satisfactory therapeutic effect and recovered well.Conclusion The interventional therapy has definite therapeutic effect on hemobilia induced by hepatic artery PsAn.The technique is worthy of popularized clinically due to its features of simplicity,safety and reliablity.
