ABSTRACT
OBJECTIVE：To systematically e valuate the efficacy and safety of duloxetine in the improvement of pain symptoms of knee osteoarthritis （KOA），and to provide evidence-based reference for clinical treatment of KOA. METHODS ：Retrieved from PubMed，Embase，Medline，Cochrane Library ，CNKI，VIP and Wanfang database ，during the establishment of the database to Sept. 2019，RCTs about duloxetine （trial group ）vs. placebo （control group ）in the improvement of pain symptoms of KOA were collected. After data extraction and quality evaluation using Cochrane system evaluator ’s manual 5.1.0，Meta-analysis was performed by using Stata 14.0 software for WOMAC total score ，WOMAC pain score ，WOMAC stiffness score ，WOMAC function score and BPI-S score ，as well as the incidence of adverse reaction such as dry mouth ，somnolence and nausea. RESULTS：A total of 6 RCTs were included ，involving 2 059 patients. Meta-analysis results showed that WOMAC total score [MD＝－0.34，95％CI（－0.48，－0.20），P＜0.05]，WOMAC pain score [MD ＝－0.41，95％CI（－0.54，－0.29），P＜0.05]， WOMAC stiffness score [MD ＝－0.24，95％ CI（－0.37，－0.12），P＜0.05]，WOMAC function score [MD ＝－0.43，95％CI （－0.55，－0.31），P＜0.05]，BPI-S score [MD ＝－0.38，95％CI（－0.48，－0.28），P＜0.05] of trial group were significantly lower than those of control group ；the incidence of dry mouth [RR ＝3.55，95％CI（2.00，6.29），P＜0.05]，somnolence [RR ＝3.23， 95％CI（1.88，5.54），P＜0.05] and nausea [RR ＝6.95，95％CI（2.99，16.15），P＜0.05] in trial group were significantly higher than control group ，with significant difference. CONCLUSIONS ：Duloxetine can relieve the pain and improve knee function in patients with KOA ，but it is necessary to pay attention to its adverse reactions.
ABSTRACT
OBJECTIVE:To observe clinical efficacy and safety of minocycline for acute retrograde pulpitis (ARP) and its ef fects on pain.METHODS:One hundred (100 teeth) ARP patients in Hospital of Qingdao Agriculture University and the Affiliated Hospital of Medical College during Jan.-Oct.in 2015 were divided into observation group and control group according to random number table,with 50 cases in each group (50 teeth).Control group was given root canal therapy of Formaldehyde cresol formocresol solution;observation group was given was given root canal therapy of Minocycline hydrochloride cream.Both groups were re checked 3 days later,and therapeutic efficacy was evaluated after 5 month follow-up;pain score,IL-2 and TNF-α levels were ob served before and 3 d after treatment,and the occurrence of ADR was recorded in 2 groups.RESULTS:The total response rate of observation group was 98.00％,which was significantly higher than 86.00％ of control group,with statistical significance (P＜ 0.05).There was no statistical significance in percussion pain score,mobility score,IL-2 and TNF-αt levels between 2 groups before treatment (P＞0.05).Three days after treatment,percussion pain score,mobility score,IL-2 and TNF-α levels of 2 groups were significantly decreased;the observation group was significantly lower than the control group,with statistical significance (P＜ 0.05).There was no statistical significance in the incidence of ADR between 2 groups (P＞ 0.05).CONCLUSIONS:Minocycline shows significantly therapeutic efficacy for ARP,and can effectively improve pain symptoms with good safety.
