Re-evaluation of systematic reviews of acupuncture and moxibustion for children with cerebral palsy / 中国针灸

OBJECTIVE@#To assess the methodological quality, report quality and evidence quality of the Meta-analysis and systematic reviews of acupuncture and moxibustion for children with cerebral palsy, aiming to provide decision-making basis for clinical treatment.@*METHODS@#The systematic reviews and Meta-analysis of acupuncture and moxibustion for children with cerebral palsy were searched in CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed and EMbase. The retrieval time was from the database establishment to June 30th, 2022. AMSTAR 2 (a measurement tool to assess systematic reviews) was used to evaluate the methodological quality， and PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and GRADE was used to evaluate the quality of evidence.@*RESULTS@#A total of 14 systematic reviews were included, including 37 primary outcome indexes. According to AMSTAR 2 evaluation results, there were 4 low quality studies, 10 very low quality studies, and low scores on items 2, 4, 7, 10 and 16. PRISMA scores ranged from 15 to 25, and the main reporting problems reflected in structured abstracts, program and registration, retrieval, and funding sources, etc. According to the GRADE classification results, there were 3 high quality evidences, 7 medium quality evidences, 10 low quality evidences and 17 very low quality evidences. The main downgrading factors were limitations, imprecision and publication bias.@*CONCLUSION@#Acupuncture and moxibustion has a certain effect for cerebral palsy in children, but the quality of methodology, reporting and evidence in the included literature is poor, and the comparison of curative effect between different acupuncture and moxibustion methods is unclear.

Postoperative rehabilitation effect and influence factors of adult prelingual deafness with cochlear implant / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate whether pre-lingual deafness adult caused by inadequate auditory compensation in childhood can benefit from cochlear implants and the related influencing factors. Methods: A total of 26 prelingual deafness as experimental group [11 males and 15 females, the age of operation was (24.5±5.7) years] and 13 postlingual deafness as control group [5 males and 8 females, the age at the time of operation was (42.2±11.4) years] were recruited. Objective assessment included hearing threshold and speech recognition rate tests while wearing cochlear implants. Subjective assessment used Nijmegen Cochlear Implant Questionnaire to assess hearing-related quality of life of subjects. The changes of hearing ability in the prelingual deafness group before and after operation and the differences with the postlingual deafness group were compared, and the correlation between speech recognition ability and the age diagnosed as severe or profound deafness, the age of hearing aid invalid, and duration of wearing cochlear implant were analyzed as factor indicators. All statistical results were analyzed by SAS 9.4 software. Results: In terms of objective indicators, the speech recognition rate of pre-lingual deafness was significantly lower than that of post-lingual deafness [(35.4±28.0)% vs (80.9±8.0)%,t=7.67, P<0.001], while there was no statistical difference in hearing threshold between the two groups [(34.8±4.0) dB HL vs (33.1±3.7) dB HL, t=1.30, P>0.05]. The indicators in the subjective questionnaire showed that the prelingual deafness group was only weaker in advanced sound perception, confidence and total mean score than the post-lingual deafness group (P<0.05), and there was no significant difference in other aspects(P>0.05), meanwhile, all indicators of the prelingual deafness group were significantly improved compared with the preoperative level (P<0.001). There was a moderate positive correlation between the hearing quality and the speech recognition rate in the prelingual deafness group(r=0.51, P=0.008). The regression analysis showed that the invalid age of hearing aid was the exact influencing factor of speech recognition rate. Conclusions: Certain prelingual deaf adults can adapt to cochlear implants and obtain different degrees of auditory assistance. Compared with the improvement of objective auditory ability assessment, the patient who received cochlear implantation gain more improvement in auditory related quality of life subjectively. The ineffective age of preoperative hearing aid is an important factor, which needs to be aroused sufficient preoperative attention.

Protective effect of astragaloside on renal injury induced by radiation through toll-like receptor 4/nuclear factor kappa B pathway / 解剖学报

Objective To explore whether astragaloside IV (AS-IV) can protect radiation-induced kidney injury through toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB)-mediated signaling pathway. Methods The mice were randomly divided into normal control group, DMSO solvent group, irradiation group (IR), IR + AS-IV 20 mg/kg group and IR + AS-IV 40 mg/kg group. One month after intraperitoneal injection of AS-IV, the mice were irradiated with 8 Gy 60Coγ and to the content of serum creatinine (Cr) and uric acid (BUA) in serum were determined, HE and immunohistochemical staining, and expression of TLR4/NF-κB signaling pathway related protein in kidney were performed. Results Compared with the control group, the levels of Cr and BUA in the serum of the radiation group increased significantly (P<0.001), glomerular atrophy and tubular expansion, TLR4 and myeloid differentiation factor 88(MyD88) positive expression increased significantly (P< 0.001), and the expression of TLR4/NF-κB signaling pathway-related proteins[ TLR4, MyD88, NF-κB, interleukin-1 β (IL-Iβ), tumor necrosis factor α (TNF-α)] increased significantly (P< 0.01); AS-IV pretreatment can reduce the content of Cr and BUA in serum (P<0.05, P<0.01 or P<0.001), significantly improve the pathological response caused by radiation, and reduce the expression of TLR4/NF-κB signaling pathway-related proteins (P<0.05 or P<0.01). Conclusion AS-IV may down-regulate the release of inflammatory factors through the TLR4/NF-κB signaling pathway, thereby improving radiation-induced kidney injury in mice and playing a protective role.
