Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

Aim To study the regulatory effect of acupuncture pretreatment on ferroptosis of nerve cells in rats with ischemic stroke.Methods Sixty SD rats were randomly divided into sham middle cerebral artery occlusion(MCAO)group,MCAO group,and acupuncture+MCAO group.In the acupuncture+MCAO group,the acupuncture points of DU26,PC6,and SP6,were selected for acupuncture pretreatment,once a day for a total of 5 days.After pre-treatment,MCAO or sham MCAO models were prepared.The Zausinger sextintegral method was used to score the neuro-logical function of rats,and the infarct volume of brain tissue was calculated by TTC staining.Electron microscopy was used to observe the pathomorphological changes of brain tissue.The iron content was detected by colorimetric method,the content of malondialdehyde(MDA)and glutathione(GSH)was determined by ELISA,and the expression of glutathione peroxidase 4(GPX4)was detected by immunofluorescence.Results Compared with the sham MCAO group,the MCAO group had a decrease in neurological function scores,a significant increase in infarct volume,a decrease in the number of mitochondria under electron microscopy,a rupture and vacuolization of the inner mitochondrial cristae,an in-crease in the contents of iron and MDA in brain tissue,and a decrease in GSH content and GPX4 expression.Compared with the MCAO group,the acupuncture+MCAO group had an increase in neurological function scores,a decrease in infarct volume,a large number of mitochondria under electron microscopy,a clear structure,a decrease or disordered arrangement of some mitochondrial crest structures,a decrease in the contents of iron and MDA in brain tissue,and an increase in GSH content and GPX4 expression.Conclusion Acupuncture pretreatment can alleviate neurological damage in rats,and its mechanism may be related to regulating iron,GSH and MDA contents in brain tissue,and GPX4 expression,improving cell antioxidant capacity and inhibiting nerve cell ferroptosis.

Cell is the most basic unit of life,and normal metabolism is the key to cell growth and development.Reactive oxygen species(ROS)are important regulators of cell function,and hypoxi-a-inducible factor-1 alpha(HIF-1α)is a ROS receptor,which can activate transient receptor poten-tial vanilloid(TRPV)channel.TRPV is a sensor for temperature,pain,and osmotic pressure.Changes in the environment can induce changes in the activity of TRPV channel,which regulates various physiological and pathological processes of cells through its downstream signaling path-ways.Low temperature plasma can regulate cellular TRPV channel activity through HIF-1α.This article mainly reviews the effect of HIF-1α on cell function through TRPV channel,which has ref-erence significance for future research on various diseases related to TRPV channel and their pre-vention and treatment,as well as provides a new idea for using low temperature plasma technology to treat diseases through regulating TRPV channel.

Objective To analyze the relationship between expression levels of long non-coding RNA(LncRNA)LINC00342 and microRNA-203a-3p(miR-203a-3p)in colorectal cancer tissue and the prognosis of patients within 5 years after surgery.Methods Samples of colorectal cancer tissue and paracancer tissue of 133 patients with colorectal cancer were collected.Expression levels of LncRNA LINC00342 and miR-203a-3p were detected by fluorescence quantitative PCR.Survival and death were recorded after 5 years of follow-up.The LncRNA LINC00342 and miR-203a-3p expressions and clinicopathological parameters in patients under different conditions were compared.The correlation between expressions of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue was analyzed,and their predictive value for the prognosis was also analyzed.Results The expression level of LncRNA LINC00342 was higher in colorectal cancer tissue than that in paracancer tissue,and the expression level of miR-203a-3p was lower in colorectal cancer tissue than that in paracancer tissue(P＜0.05).The expression levels of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue were negatively correlated(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ and lymph node metastasis were higher in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group than those in the LncRNA LINC00342 low expression group and the miR-203a-3p high expression group,respectively(P＜0.05).The 5-year overall survival rate after operation was lower in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,and higher expression level of LncRNA LINC00342 were higher in colorectal cancer tissue of the death group than those in the survival group,and the expression level of miR-203a-3p was lower than that in the survival group(P＜0.05).Low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,high expression of LncRNA LINC00342 and low expression of miR-203a-3p were independent risk factors for death within 5 years after colorectal cancer surgery(P＜0.05).The combined predictive value of LncRNA LINC00342 and miR-203a-3p for prognosis was greater than that of individual prediction.Conclusion LncRNA LINC00342 is higher expressed and miR-203a-3p is lower expressed in colorectal cancer tissue,and the combined detection of the two is expected to become a clinical evaluation indicator for predicting postoperative survival.

Cognitive dysfunction is one of the common central nervous systems (CNS) complications of diabetes mellitus, which seriously affects the quality of life of patients and results in a huge economic burden. The glymphatic system dysfunction mediated by aquaporin-4 (AQP4) loss or redistribution in perivascular astrocyte endfeet plays a crucial role in diabetes-induced cognitive impairment (DCI). However, the mechanism of AQP4 loss or redistribution in the diabetic states remains unclear. Accumulating evidence suggests that peripheral insulin resistance target tissues and CNS communication affect brain homeostasis and that exosomal miRNAs are key mediators. Glucose and lipid metabolism disorder is an important pathological feature of diabetes mellitus, and skeletal muscle, liver and adipose tissue are the key target insulin resistance organs. In this review, the changes in exosomal miRNAs induced by peripheral metabolism disorders in diabetes mellitus were systematically reviewed. We focused on exosomal miRNAs that could induce low AQP4 expression and redistribution in perivascular astrocyte endfeet, which could provide an interorgan communication pathway to illustrate the pathogenesis of DCI. Furthermore, the mechanisms of exosome secretion from peripheral insulin resistance target tissue and absorption to the CNS were summarized, which will be beneficial for proposing novel and feasible strategies to optimize DCI prevention and/or treatment in diabetic patients.

Ischemic stroke (IS) is a severe cerebrovascular disease with a high incidence, mortality, and disability rate. The first-line treatment for IS is the use of recombinant tissue plasminogen activator (r-tPA). Regrettably, numerous patients encounter delays in treatment due to the narrow therapeutic window and the associated risk of hemorrhage. Traditional Chinese medicine (TCM) has exhibited distinct advantages in preventing and treating IS. TCM enhances cerebral microcirculation, alleviates neurological disorders, regulates energy metabolism, mitigates inflammation, reduces oxidative stress injuries, and inhibits apoptosis, thereby mitigating brain damage and preventing IS recurrence. This article summarizes the etiology, pathogenesis, therapeutic strategies, and relationship with modern biology of IS from the perspective of TCM, describes the advantages of TCM in the treatment of IS, and further reviews the pharmacodynamic characteristics and advantages of TCM in the acute and recovery phases of IS as well as in post-stroke complications. Additionally, it offers valuable insights and references for the clinical application of TCM in IS prevention and treatment, as well as for the development of novel drugs.

Objective To analyze the microflora structure and abundance of ileum and colon of SPF male SD rats by high-throughput sequencing technique. MethodsThe ileal and colonic lumen contents of 30 SPF male SD rats were collected, the total bacterial DNA in the contents was extracted and amplified by PCR. The V3-V4 region of bacterial 16S rRNA in the samples was sequenced using Illumina NovaSeq sequencing platform. Then the species structure and abundance of the intestinal flora were analyzed at the phylum and genus level based on validated data. The diversity and differences between ileal and colonic flora were analyzed using the QIIME software (amplicon) analysis tool. The Tax4Fun program was applied to predict the dominant gene enrichment pathways of ileal and colonic flora. ResultsAt the phylum level, the dominant microflora in the ileum of male SD rats were Firmicutes and Actinobacteria, accounting for more than 98%. The dominant colonic microbial community were mainly Firmicutes and Bacteroidetes, accounting for more than 95%. At the genus level, Lactobacillus and Alistipes were the predominant bacteria in the ileum. The colon was dominated by Lactobacillus and Romboutsia. In terms of flora diversity, the alpha diversity of colonic flora including richness index (Chao1 index) and diversity index (Shannon index) were significantly higher than those of ileum (P < 0.01), and the structural variability of the composition of its flora species was smaller than that of ileum; the ileal flora with significant structural variability were mainly of the phylum Firmicutes, Romboutsia, Peptostreptococcaceae, while the colonic flora had significant structural differences in Bacteroidales. In terms of flora function, the ileal flora dominant genes were significantly enriched in lipid-like metabolism, polyketide metabolism, membrane transport, biodegradation and other pathways, while the colonic flora dominant genes were significantly enriched in glycan biosynthesis metabolism, energy metabolism, biosynthesis of cofactor and vitamins and other products, and other pathways. ConclusionThere are significant differences in structure and abundance between the ileal and colonic flora of SPF male SD rats, and the abundance and diversity of colonic flora are higher than those of ileal flora.

Objective To evaluate the quality of the clinical trial literatures published on the treatment of COVID-19 with TCM, find out the shortcomings and put forward corresponding suggestions, in order to promote TCM against COVID-19. Methods "COVID-19", "New Coronavirus Pneumonia", "TCM", "Chinese Medicine", "Clinical Trial", "Lianhua Qingwen", "Huoxiang Zhengqi", "Jinhua Qinggan", and other keywords were used to search relevant literatures in CNKI and PubMed database. Among the all the screened relevant literatures on the treatment of COVID-19 with TCM, the literature quality was assessed according to evaluation criteria of clinical trial literatures. Results A total of 463 papers related to the treatment of COVID-19 with TCM were obtained. 440 papers on theoretical research on the network pharmacology mechanism of Chinese medicine treatment of COVID-19 were excluded. Among the 23 articles included in the quality analysis, there are 3 randomized controlled studies, 1 multi-center prospective randomized controlled trial, 2 disease case report trials, and 5 uncontrolled single arm studies, 5 controlled trials and 7 retrospective studies. In the period of more than half a year, although many clinical trial documents of TCM for the treatment of COVID-19 have been published, the clinical trial design reflected in most TCM clinical trials were not standardized. There are problems in "randomness and rationality", such as no control group, no randomization design, only case studies, no blinding method in controlling bias, and insufficient objectivity in the evaluation criteria of efficacy. All of these need to be improved. Conclusion The treatment of new coronavirus pneumonia with TCM still requires more and standardized clinical trial verifications and publications to generate strong evidence-based results, such as adding control groups, increasing sample size, and using blinding methods to increase the credibility of clinical trials.
