RESUMEN
OBJECTIVE: To systematically evaluate the efficacy and safety of acupuncture in the treatment of the vascular cognitive impairment (VCI) associated with cerebral small vessel disease (CSVD-VCI) and to provide a theoretical basis for clinical acupuncture treatment for CSVD-VCI. METHOD: Various databases, including China National Knowledge Infrastructure, Wanfang Data, Chinese Science and Technology Journal Database, Chinese BioMedical Literature Service System, PubMed, the Cochrane Library, and EBSCOhost, were searched for randomized controlled trials (RCTs) related to acupuncture treatment for CSVD-VCI. The quality of the included trials was evaluated, and a meta-analysis was conducted using the Review Manager 5.4 software. RESULTS: Ten articles on RCTs were included, involving 761 patients, i.e., 381 in the acupuncture group and 380 in the control group. The meta-analysis results indicated that the use of acupuncture alone and acupuncture alongside other therapies for CSVD-VCI could improve the overall clinical response rate [odds ratio = 3.51, 95% confidence interval (CI) = (2.05, 6.00), P < 0.00001], increase the patients' Montreal Cognitive Assessment scores [mean difference (MD) = 3.33, 95%CI (2.98, 3.68), P < 0.00001], Mini-Mental State Examination scores [MD = 2.78, 95%CI (2.51, 3.06), P < 0.00001], and activities of daily living scores [MD = 6.30, 95%CI (4.22, 8.37), P < 0.00001], and shorten the latency of auditory evoked potential P300 [MD = -14.67, 95%CI (-19.54, -9.80), P < 0.00001]. CONCLUSION: Acupuncture alone and acupuncture alongside other therapies are superior to non-acupuncture-based therapies in the treatment of CSVD-VCI. However, due to the small number of relevant available articles and their general low quality, this conclusion may be biased. More clinical RCTs with a larger sample size and higher quality are needed to support this theory.

Objective: Neonatal hyperbilirubinemia is caused by the excessive production of bilirubin and decreased excretion ability in the neonatal period. It leads to a concentration of blood bilirubin that exceeds a certain threshold. Yinzhihuang oral liquid (YZH) is a traditional Chinese medicine mixture used in the treatment of neonatal hyperbilirubinemia in China. This article systematically explores the pharmacological mechanisms by which YZH acts in the treatment of neonatal hyperbilirubinemia through network pharmacology at the molecular level. Methods: We adopted the method of network pharmacology, which includes active component prescreening, target gene prediction, gene enrichment analysis, and network analysis. Results: According to the network pharmacological analysis, 8 genes (STAT3, AKT1, MAPK14, JUN, TP53, MAPK3, ESR1, and RELA) may be targets of YZH in the treatment of neonatal hyperbilirubinemia. In addition, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses showed that YZH may regulate antioxidation, modulate lipid metabolism, and have anti-infective properties. Conclusion: In this study, the pharmacological action and molecular mechanisms of YZH were predicted as a whole. It was found that YZH is a promising drug for treating oxidative stress due to bilirubin, as it reduces immunosuppression and helps to eliminate virus infection.
RESUMEN
Huangqi, the dried root of Radix Astragali, is an essential herb in Traditional Chinese Medicine and has been used to promote hematopoiesis for centuries. Astragalus polysaccharide (ASPS), the bioactive compound of Huangqi, serves a crucial role in hematopoiesis. The aim of the present study was to investigate the hematopoietic effects, in particular the thrombopoietic effects, and the molecular mechanisms of ASPS using an irradiationinduced myelosuppressive mouse model. Colonyforming unit assays, flow cytometric analysis of apoptosis, ELISAs, Giemsa staining and western blotting were performed to determine the hematopoietic and antiapoptotic effects of ASPS. The results demonstrated that ASPS enhanced the recovery of red blood cells at day 21 following treatment, as well as platelets and white blood cells at day 14. In addition, ASPS promoted colony formation in all lineages (megakaryocytes, granulocyte monocytes, erythroid cells and fibroblasts). The morphological study of the bone marrow demonstrated that trilineage hematopoiesis was preserved in the ASPS and thrombopoietin (TPO)treated groups compared with the control group. The overall cellularity (mean total cell count/area) of the ASPStreated group was similar to that of the TPOtreated group. Additionally, in vitro experiments indicated that treatment with 100 µg/ml ASPS exhibited the maximum effect on colony formation. ASPS attenuated cell apoptosis in megakaryocytic cells via inhibiting the mitochondrial caspase3 signaling pathway. In conclusion, ASPS promoted hematopoiesis in irradiated myelosuppressive mice possibly via enhancing hematopoietic stem/progenitor cell proliferation and inhibiting megakaryocytes apoptosis.

AIM: To investigate the effect of electroacupuncture on corticotropin-releasing hormone (CRH) in the colon, spinal cord, and hypothalamus of rats with chronic visceral hypersensitivity. METHODS: A rat model of chronic visceral hypersensitivity was generated according to the internationally accepted method of colorectal balloon dilatation. In the 7(th) week after the procedure, rats were randomly divided into a model group (MG), electroacupuncture group (EA), and sham electroacupuncture group (S-EA). After treatment, the abdominal withdrawal reflex (AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry (EnVision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and mRNA in the colon, spinal cord, and hypothalamus. RESULTS: The sensitivity of the rats to the colorectal distension stimulus applied at different strengths (20-80 mmHg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased (P < 0.01). After conducting EA, the AWR scores of the rats were decreased compared with MG rats. The relative expression of CRH mRNA in the colon, spinal cord, and hypothalamus of MG rats was significantly increased compared with NG rats (P < 0.01). CRH mRNA in the colon and spinal cord of EA and S-EA rats was decreased to varying degrees (P > 0.05) compared with normal rats (NG). However, the decrease in EA compared with MG rats was statistically significant (P < 0.01). The average optical density of CRH expression in the colon of the MG rats was significantly enhanced compared with NG (P < 0.05), while the average optical density of CRH expression in the EA and S-EA rats was significantly decreased compared with MG rats (P < 0.01, P < 0.05, respectively). Compared with MG rats, the CRH concentration in the spinal cord of EA rats was significantly reduced (P < 0.01), but there was no significant change in S-EA rats (P > 0.05). CONCLUSION: Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and mRNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.
