A large number of existing and newly published studies have demonstrated the analgesic effect of electroacupuncture(EA) in complete Freund's adjuvant(CFA) rat model, necessitating a new and comprehensive review. To evaluate the curative effect of EA on thermal hyperalgesia in CFA rats, and to explore parameters that influence treatment effects, studies of EA treatment on thermal hyperalgesia of CFA rat model were identified from nine databases up to June 17, 2017. Outcome measure was heat pain threshold. All the data were analyzed using Stata 14.0/MP software. 26 studies identified included 801 rats. The quality score of the studies ranged from 3 to 6, with a mean of 4.08. The effect of EA group was improvement in outcome compared with CFA group. In subgroup analyses, frequency 2, 100, 2/100 or 20-100 Hz. acupoint Huántiào(环跳GB30),Kūnlún(昆仑 BL60) +Xuánzhōng(悬钟 GB39), Zúsānlī(足三里 ST36) +BL60 or ST36+Sānyīnjiāo(三阴交SP6), retention time 20 or 30 min, treatment time for post-CFA injection immediately, the same day as CFA injection, post-CFA injection 24 or 48 h and interval 24 or 48 h all can improve the effect on CFA rat heat pain threshold. These results show that there is positive effective of EA in CFA-induced pain,different parameters have different effects on EA treatment of CFA heat hyperalgesia, however, because of the number of eligible researches and the high risk of bias, the evidence supporting this conclusion is limited.展开更多

The aim of the study was to evaluate therapeutic efficacy of QS using FCA in Trypanosorna congolense infection. GrouPs treated with QS and FCA had parasite disappeared in peripheral circulation 2 days pi, relapse was observed one week later. Effect of treatment on rectal temperature shows no significance (p 〈 0.05), normalization of rectal temperature occurred in QS and FCA treated groups (34.1℃) than untreated (42.8 ℃), QS (37.4 ℃) and FCA (35.92 ℃) treated groups. Mean body weight was significant (p 〈 0.001) in QS and FCA, QS, and FCA groups. Packed cell volume and hemoglobin concentration for untreated groups were lower, but increased in QS, FCA, QS and FCA treated groups, indicating anemia amelioration. White blood cell counted in untreated, QS and FCA treated groups showed no significance (p 〈 0.05), however, there was leukocytosis due to lymphocytosis in QS and FCA treated group (6.79 × 10^3/μl) compared with untreated and other groups. There was comparative decrease in serum liver enzymes in QS and FCA treated group than other groups. Therefore, QS at lower recommended dose with FCA may enhance efficacy of QS in trypanosomiasis.展开更多
