OBJECTIVE: To observe the clinical efficacy of acupuncture on mild cognitive impairment (MCI) and its effect on gut microbiota. METHODS: A total of 62 MCI patients were randomly divided into an experimental group (31 cases, 2 cases dropped out) and a control group (31 cases). Both groups received exercise and cognitive training. In addition, the experimental group underwent acupuncture treatment at acupoints including Baihui (GV20), Sishencong (EX-HN1), and bilateral Fengchi (GB20), Xuanzhong (GB39), Zusanli (ST36), Yanglao (SI6), Xinshu (BL15), and etc., once every other day, three times per week, for a total of 12 weeks. Before and after treatment, the Montreal cognitive assessment (MoCA) and mini-mental state examination (MMSE) scores were evaluated in the two groups, changes in gut microbiota were detected using 16S rDNA sequencing technology. The clinical efficacy was assessed after treatment. RESULTS: Compared before treatment, MoCA and MMSE scores were increased in both groups after treatment (P<0.001), with higher scores in the experimental group than those in the control group (P<0.001, P<0.05). After treatment, the relative abundance of Faecalibacterium, Clostridia, and Ruminococcaceae was increased in the experimental group compared with that before treatment (P<0.05). Moreover, the relative abundance of Faecalibacterium in the experimental group was higher than that in the control group (P<0.05). The total effective rate was 82.8% (24/29) in the experimental group, which was higher than 61.3% (19/31) in the control group (P<0.05). CONCLUSION Acupuncture could improve cognitive dysfunction in patients with MCI, and its mechanism may be related to increasing the relative abundance of butyrate-producing bacteria such as Faecalibacterium, Clostridia, and Ruminococcaceae, maintaining the intestinal barrier, and inhibiting related inflammatory responses.

Objective:To investigate the interventional and protective effect of low-dose L-carnitine(LC)against reproductive system damage in male Wistar rats during acute exposure to simulated high-altitude environment.Methods:A total of 24 specific pathogen-free male Wistar rats,aged 12 weeks,were randomly divided into control group,high-altitude model group,and LC intervention group[intraperitoneal injection of LC at a dose of 50 mg/(kg·d)],with 8 rats in each group.The rats in the control group were fed under normal conditions(at an altitude of approximately 1 500 m),those in the high-altitude model group,and those in the LC intervention group were fed in a hypobaric oxygen chamber(at a simulated alti-tude of 6 000 m).The rats were sacrificed after 3 days.The testis was collected to calculate testicular index;the semen was collected from the epididymis,and the Weili sperm quality analysis system was used to assess sperm quality;blood samples were collected from the abdominal aorta,and ELISA kits were used to measure the serum levels of testosterone(T),luteinizing hormone(LH),and follicle-stimulating hormone(FSH);testicular tissue samples were collected,and biochemical kits were used to measure the activity of reactive oxygen species(ROS),malondialdehyde(MDA),and superoxide dismutase(SOD);testicular tissue was collected to prepare HE and electron microscopy sections,and a light microscope and a transmission electron microscope were used for observation.Results:Com-pared with the blank control group,the high-altitude model group had significant increases in the levels of T,LH,and FSH(P<0.01),testicular tissue damage under the light microscope,and changes in the morphology of spermatogenic cells,including mitochondrial al-terations,membrane edema,loss of cristae,swelling of the matrix,and local dissolution,as well as significant increases in the levels of ROS and MDA(P<0.01)and a significant reduction in SOD activity(P<0.01).Compared with the high-altitude model group,the LC intervention group had a significant increase in the level of T(P<0.01),significant reductions in the levels of FSH and LH(P<0.01),and significant improvements in the pathological changes of testicular tissue,with no marked mitochondrial injury,and there were sig-nificant reductions in the levels of ROS and MDA(P<0.01)and a significant increase in SOD activity(P<0.01).There was no signifi-cant difference in testicular index between groups(P>0.05).The high-altitude model group had a significantly lower sperm count than the blank control group(P<0.05),while there was no significant difference in sperm count between the LC intervention group and the blank control group(P>0.05);there was no significant difference in sperm motility between groups(P>0.05).Conclusion:Low-dose LC can improve reproductive system damage in rats during acute exposure to simulated high-altitude environment,possibly by alleviat-ing oxidative stress response.

Solid-phase extraction(SPE)combined with surface-enhanced Raman spectroscopy(SERS)has emerged as a promising analytical technique for detection and analysis of trace components in complex sample matrices.SPE enriches analytes through selective adsorption and solvent elution,effectively increasing the concentration and signal intensity.SERS enables ultra-sensitive and highly selective molecular analysis through the use of SERS-active substrates engineered to amplify Raman signals.The integration of these two techniques overcomes the limitations of conventional Raman spectroscopy in low-concentration detection field,while significantly improving sample preparation efficiency and analytical accuracy.This review provided a comprehensive overview of the characteristics of three SPE-SERS coupling modes,including two-step,one-step,and online integration.Special emphasis was placed on recent advancements in one-step SPE-SERS approaches based on novel functional adsorbent materials such as graphene,metal-organic frameworks,covalent organic frameworks,and molecularly imprinted polymers.Furthermore,future directions and development prospects of SPE-SERS technology were discussed.
