OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.

Objective To systematically assess the effectiveness and safety of acupuncture and moxibustion for treatment of rheumatoid arthritis. Methods Articles were searched from databases, i.e., CNKI, VIP, WanFang Data, CBM, Embase, and PubMed. Articles about RCT on acupuncture and moxibustion for rheumatoid arthritis and traditional medicine therapy were under meta-analysis. Results Totally 24 articles involving 2006 patients were included. The results of meta-analysis indicated that the overall effective rate of treatment in the group receiving acupuncture and moxibustion was higher than that in the drug group, with statistical significance [OR=2.73, 95%CI (2.18, 3.41), Z=8.78, P<0.000 01]. Sub-group analysis showed that:acupuncture and moxibustion showed statistical significance in decreasing serum RF levels compared with drug therapy [MD=-2.92, 95%CI (-5.60, -0.25), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum ESR levels compared with drug therapy [MD=-2.99, 95%CI (-4.78, -1.21), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum CPR levels compared with drug therapy [MD=-1.44, 95%CI (-2.44, -0.44), P <0.05]. Conclusion The overall effective rates of acupuncture and moxibustion for rheumatoid arthritis and the decreasing levels of RF, ESR, CRP are superior to drug therapy, but it still needs larger samples, multi-center, and high quality RCT to verify.

Objective To investigate the impact ofα?lipoic acid(ALA)treatment on sepsis?induced acute kidney injury in rats and explore the mechanisms. Methods A total of 32 male SD rats were randomized into 4 groups:normal control group(group A),ALA?treated control group (group B),sepsis group(group C)and sepsis with ALA treated group(group D). Group A and B underwent sham operation,while CLP operations were conducted in group C and D. Rats in both group B and group D were then administered with 200 mg/kg ALA by oral gavage immediately after the surgical procedure. Twenty?four hours after the surgical procedure blood samples were obtained for the evaluation of creatinine,BUN,TNF?α,IL?6 and IL?1β. Rat kidneys were rapidly removed for PAS stain. Western blot was employed to determine the expression of NF?κB. Results Pathologi?cal changes of kidney were induced by sepsis and the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly increased by 178%,66%, 55%,114%and 110%(P<0.01). respectively;simultaneously the phosphorylation and nuclear expression of NF?κB p65 in kidney tissues were significantly increased by 144%and 102%(P<0.01). Sepsis?induced acute kidney injury also significantly reduced the expression of IκBαby 61%(P<0.01). These changes were significantly suppressed by early ALA treatment. Compared with C group,the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly decreased by 48%,26%,25%,37%and 40%(P<0.05),respectively,and the relative expression of IκBαwas increased by 103%(P<0.05). Conclusion The present study demonstrated that ALA can suppress the activation of NF?κB,thus ameliorat?ing sepsis?related acute kidney injury.
