Objective:To investigate the changes of artemin protein expression in diabetic peripheral neuropathy (DPN) and to explore the regulatory effect of human adipose-derived stem cell (ADSC) exosomes on the change of artemin protein expression.Methods:This research was a prospective observational clinical research combined with experimental research. Thirteen DPN patients (9 males and 4 females, aged 32 to 68 years) who were admitted to the First Affiliated Hospital of Air Force Medical University (hereinafter referred to as our hospital) from May 2022 to October 2023 and met the inclusion criteria were selected as DPN group, and 5 non-diabetes patients (4 males and 1 female, aged 29 to 61 years) who were admitted to our hospital in the same period of time and met the inclusion criteria were selected as control group. The toe nerve or sural nerve tissue in the abandoned tissue after debridement or amputation of patients in the two groups was collected. The pathological changes of nerve tissue were observed after hematoxylin-eosin staining; the protein expressions of S100β and artemin in nerve tissue were observed after immunofluorescence staining, and the artemin protein expression was quantified; the protein and mRNA expressions of artemin were detected by Western blotting and real-time fluorescent quantitative reverse transcription polymerase chain reaction, respectively (the sample number in DPN group and control group was 13 and 5, respectively). Twelve male C57BL/6 mice aged 3 to 5 days were collected to isolate Schwann cells, and the cells were divided into conventional culture group cultured routinely, high glucose alone group (cultured with high concentration of glucose solution only), and high glucose+exosome group (cultured with high concentration of glucose solution and extracted human ADSC exosomes). After 24 hours of culture, the cell proliferation activity was detected by cell counting kit 8 ( n=6). After 48 hours of culture, the protein expression of artemin was detected by Western blotting ( n=3). Results:Compared with those in control group, the neural supporting cells decreased and the inflammatory cells increased in the nerve tissue of patients in DPN group, showing typical manifestations of nerve injury. Immunofluorescence staining showed that compared with those in control group, the nuclei was more, and the protein expression of S100β was lower in nerve tissue of patients in DPN group. The protein expression of artemin in nerve tissue of patients in DPN group was 71±31, which was significantly lower than 1 729±62 in control group ( t=76.92, P<0.05). Western blotting detection showed that the protein expression of artemin in nerve tissue of patients in DPN group was 0.74±0.08, which was significantly lower than 0.97±0.06 in control group ( t=5.49, P<0.05). The artemin mRNA expression in nerve tissue of patients in DPN group was significantly lower than that in control group ( t=7.65, P<0.05). After 24 hours of culture, compared with that in conventional culture group, the proliferation activities of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the proliferation activity of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). After 48 hours of culture, compared with those in conventional culture group, the protein expressions of artemin of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the protein expression of artemin of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). Conclusions:The protein expression of artemin in nerve tissue of DPN patients is lower than that in normal nerve tissue, which may be related to the reduction of proliferation activity of Schwann cells by high glucose. Human ADSC exosomes may improve the proliferation activity of Schwann cells by increasing artemin protein expression, thereby delaying the progression of DPN.

Objective:To explore the influence and its mechanism of allogeneic dermal papilla cells (DPCs) on the wound healing of full-thickness skin defects in mice.Methods:This study was an experimental study. DPCs were isolated from the whisker follicles of five 6-week-old male C57BL/6J mice by combining microdissection with collagenase digestion and were successfully identified. Eighteen 8-week-old male C57BL/6J mice were divided into phosphate buffer solution (PBS) group and DPC group according to the random number table, with 9 mice in each group, and the full-thickness skin defect wound model was created on the back of all mice. On day 2, 4, and 6 after injury, the mice in DPC group were administered 100 μL of cell suspension containing 1×10 6 DPCs of the 4 th passage by subcutaneous injection around the wound, and the mice in PBS group was administered an equal volume of PBS. On day 3, 7, 10, and 14 after injury, the wound healing and hair growth of mice in two groups were observed, and the residual wound area was measured, and the hair coverage area on the wound of mice in two groups was measured on day 14 after injury. On day 14 after injury, the wound tissue samples of mice in two groups were collected. Hematoxylin-eosin staining was performed to observe the condition of newborn hair follicles and the number was counted, Masson staining was performed to observe the collagen deposition in the dermis and the collagen deposition area was measured, the immunofluorescence method was used to detect the protein expressions of Wnt/β-catenin signaling pathway related molecules β-catenin and lymphoid enhancer binding factor 1 (Lef1), and Western blotting and real-time fluorescence quantitative reverse transcription polymerase chain reaction were used to detect the protein and mRNA expressions of β-catenin and Lef1, respectively. The number of samples in each experiment was 3. Results:Compared with those in PBS group, the mice in DPC group had accelerated wound re-epithelialization at each time point after injury, and more hair growth on day 10 and 14 after injury. On day 7, 10, and 14 after injury, the residual wound areas of mice in DPC group were (13.92±2.90), (3.69±1.78), and (1.09±0.14) mm 2, respectively, which were significantly smaller than (26.19±2.06), (10.84±3.59), and (6.75±2.11) mm 2 in PBS group, respectively (with t values of 5.85, 3.09, and 4.63, respectively, P values all <0.05). On day 14 after injury, the hair coverage area on the wound of mice in DPC group was (62±7) mm 2, which was significantly larger than (35±6) mm 2 in PBS group ( t=2.89, P<0.05). On day 14 after injury, compared with those in PBS group, the number of newborn hair follicles in the wound tissue of mice in DPC group was significantly increased ( t=5.43, P<0.05), and the dermal collagen deposition area was significantly reduced ( t=3.56, P<0.05). On day 14 after injury, both the immunofluorescence method and the Western blotting detection showed that the protein expressions of β-catenin (with t values of 5.49 and 4.25, respectively, P values all <0.05) and Lef1 (with t values of 7.50 and 11.54, respectively, P values all <0.05) in the wound tissue of mice in DPC group were significantly higher than those in PBS group; the mRNA expressions of β-catenin and Lef1 in the wound tissue of mice in DPC group were significantly higher than those in PBS group (with t values of 7.68 and 9.67, respectively, P<0.05). Conclusions:DPCs can accelerate the re-epithelialization of full-thickness skin defect wounds in mice by activating Wnt/β-catenin signaling pathway and promote hair follicle regeneration during the process of wound healing.

ObjectiveTo observe the efficacy and safety of Tongguan Capsule(通冠胶囊)on ventricular remodeling in patients after acute myocardial infarction (AMI), and to explore the possible mechanism. MethodsA total of 53 ST-segment elevation myocardial infarction (STEMI) patients were collected and randomly divided into 26 cases in the treatment group and 27 cases in the control group. The control group was given conventional therapy after percutaneous coronary intervention (PCI) for AMI, and the treatment group was given Tongguan Capsules (4.5 g each time, 3 times a day) on the basis of the control group. The course of treatment was 12 weeks. Echocardiographic data and stool samples were collected from subjects before and after the intervention, and left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVi), left ventricular end-systolic volume index (LVESVi), left ventricular mass index (LVMi) were measured and calculated, so as to compare the number of cases of left ventricular remodeling in the two groups. At the same time, 16S rDNA sequencing was performed on the stool samples to analyze the diversity of gut microbiota (GM), the composition of the GM, the GM difference between the groups; recording the incidence of major adverse cardiovascular events (MACEs) and adverse reactions of patients in the two groups during the study period; and performing Spearman's correlation analyses of the post-treatment flora data with LVEF, LVEDVi, LVESVi, LVM, and LVMi in the two groups. ResultsOne case fail to follow up in the treatment group and 2 cases fail to follow up in the control group, and 25 cases in each of the two groups were finally included in the analysis. LVEDVi, LVESVi, and LVMi of the control group after treatment were higher than those before treatment (P<0.05); after treatment, LVEDVi, LVESVi and LVMi in the treatment group were lower than those in the control group (P<0.05). Left ventricular remodeling occurred in 5 cases (20.00%) in the treatment group and 13 cases (52.00%) in the control group, and the incidence of left ventricular remodeling in the treatment group was lower than that in the control group (P=0.03). After treatment, the ACE estimation and Chao estimation of bacterial abundance in the treatment group were higher than that before treatment and that in the control group (P<0.05). The treatment group showed an increase in Mycobacterium anisopliae phylum and a decrease in Mycobacterium thickum, Mycobacterium anisopliae phylum, and Mycobacterium patella phylum after treatment (P<0.05). When comparing between groups after treatment, the relative abundance of Prevotella, Agathobacter, Dialister, Eubacterium coprostanoligenes group was up-reuglated and the relative abundance of Enterococcus was down-regulated in the treatment group(P<0.05 or P<0.01). There was no statistically significant difference in the incidence of MACEs and the occurrence of adverse reactions between groups during treatment (P>0.05). The results of correlation analysis showed that Prevotella were positively correlated with LVEF and negatively correlated with LVEDVi, LVESVi, LVM, and LVMi (P<0.01). Agathobacter group were negatively correlated with LVEDVi, LVESVi (P<0.01); Enterococcus group were positively correlated with LVESVi (P<0.05). ConclusionTongguan Capsules can improve ventricular remodeling in patients with acute ST-segment elevation myocardial infarction with better safety; its mechanism may be related to adjusting the enrichment of related bacteria such as Prevotella, Dialister and Enterococcus and other related bacterial genera, increasing the colonization and diversity of beneficial bacteria, and adjusting the structure of GM.

The paper reports a case of coenzyme Q10 deficiency nephrotic syndrome associated with coenzyme Q2 gene mutation and reviews the literature on this topic. The patient presented with hematuria, proteinuria, and a diminution of vision as clinical manifestations. But the proteinuria was not relieved after sufficient doses of glucocorticoids for over 2 months. The patient′s birth history was unremarkable, and his parents were both healthy and not consanguineous. Whole exome sequencing revealed that the patient had a mutation of coenzyme Q2 gene at c.973A>G(p.T325A) and c.517C>T(p.R173C). Combined with renal biopsy pathology, the patient was diagnosed with hereditary nephropathy and started the supplements of coenzyme Q10 after stopping glucocorticoid treatments immediately. After 5 weeks of therapy, the patient′s 24-h urine protein quantification decreased from 6.01 g to 1.53 g.

Metabolic-associated fatty liver disease (MAFLD), which is previously known as non-alcoholic fatty liver disease (NAFLD), represents a major health concern worldwide with limited therapy. Here, we provide evidence that ferroptosis, a novel form of regulated cell death characterized by iron-driven lipid peroxidation, was comprehensively activated in liver tissues from MAFLD patients. The canonical-GPX4 (cGPX4), which is the most important negative controller of ferroptosis, is downregulated at protein but not mRNA level. Interestingly, a non-canonical GPX4 transcript-variant is induced (inducible-GPX4, iGPX4) in MAFLD condition. The high fat-fructose/sucrose diet (HFFD) and methionine/choline-deficient diet (MCD)-induced MAFLD pathologies, including hepatocellular ballooning, steatohepatitis and fibrosis, were attenuated and aggravated, respectively, in cGPX4-and iGPX4-knockin mice. cGPX4 and iGPX4 isoforms also displayed opposing effects on oxidative stress and ferroptosis in hepatocytes. Knockdown of iGPX4 by siRNA alleviated lipid stress, ferroptosis and cell injury. Mechanistically, the triggered iGPX4 interacts with cGPX4 to facilitate the transformation of cGPX4 from enzymatic-active monomer to enzymatic-inactive oligomers upon lipid stress, and thus promotes ferroptosis. Co-immunoprecipitation and nano LC-MS/MS analyses confirmed the interaction between iGPX4 and cGPX4. Our results reveal a detrimental role of non-canonical GPX4 isoform in ferroptosis, and indicate selectively targeting iGPX4 may be a promising therapeutic strategy for MAFLD.

Tongue diagnosis is one of the diagnostic methods of Traditional Chinese Medicine (TCM), but its development has always been restricted by the lack of objective quantitative indicators. With the rapid development of computer technology and the advent of the algorithm era, the modernization of TCM tongue diagnosis has gradually become a hot research spot. This paper annalyses the literature and related patents of the modernization of tongue diagnosis and summarizes the R&D progress and application of tongue diagnosis as well as related instruments. It is found that domestic and foreign scholars focus on tongue diagnosis related research and attach importance to the formulation of relevant international standards. Tongue collection and analysis technology continues to develop; tongue diagnostic instruments are also gradually enriched. At present, their applications are extended to family self-use, but they are still mainly used in teaching, scientific research and other fields, involving the clinical efficacy evaluation of TCM, clinical case classification and health management, and there is still much room for development. In the future, we should strengthen the communication between multi-regional research centers, promote the communication among talents in different fields, constantly make up for the deficiencies and promote the development of tongue diagnosis research.
