Humanin(HN,its analogue [Gly14]-Humanin,HNG)was originally identified as an endogenous peptide that protects neuronal cells from apoptosis induced by various types of Alzheimer's disease-related insults.But the relative low content of this peptide in its natural sources limits its further characterization.An expression vector pET32a/HNG was corstructed and transformed it into E.coli BL21 trxB(DE3).HNG was expressed as a fusion protein in the soluble fraction and was purified by nickel affinity chromatography.Subsequently,the purified fusion protein was cleaved by enterokinase and was further purified by reverse-phase HPLC.A 23 mg recombinant HNG(rHNG)from 1 L bacterial culture was purified.The molecular weight of rHNG determined by ESI-MS was 2876.5 Da which was the expected size for correctly processed peptide.The N-terminal amino acid sequence of rHNG determined by Edman degradation method is identical to the theoretical sequence.Neuroprotective bioassay studies of rHNG exhibited its potential neuroprotective effect comparable to that of the natural HNG peptide.

Objective: To systematically evaluate the impact of acupuncture on exercise-induced fatigue (EIF). Methods: Scopus, Springer Link, Web of Science, PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), and China Biology Medicine Disc (CBM) were systematically searched to identify randomized controlled trials (RCTs) studying acupuncture treatment of EIF from the inception till August 2020. The risk of bias in the included studies was assessed using the Cochrane handbook. RevMan 5.3 was used to conduct statistical analysis on the extracted data. Results: A total of 11 RCTs were included for meta-analysis, involving 531 patients. It was revealed that acupuncture produced more significant effects in alleviating subjective fatigue [standardized mean difference (SMD)=-3.08, 95％ confidence interval (CI) (-4.35, -1.81), P<0.001], increasing the hemoglobin content [weighted mean difference (WMD)=3.89, 95％CI (1.37, 6.42), P=0.003], reducing the lactate dehydrogenase content [WMD=-10.63, 95％CI (-17.67, -3.59), P=0.003], reducing the blood lactic acid content [SMD=-2.65, 95％CI (-4.47, -0.83), P=0.004], and down-regulating the levels of serum creatine kinase [SMD=-0.79, 95％CI (-1.10, -0.48), P<0.001] and blood urea nitrogen [WMD=-1.47, 95％CI (-1.84, -1.11), P<0.001] than the control groups. Conclusion: Based on the existing evidence, acupuncture can be recognized as effective in improving EIF and is worthy of promotion in clinical settings.
