ObjectiveTo investigate the effect and mechanism of Banxia Shumitang plus Zhizichi Tang （BZ） on PTEN-induced kinase 1 （PINK1）/Parkin signaling pathway in regulating mitochondrial autophagy in preventing insomnia with depression. MethodsSeventy-two 6-week-old male Kunming mice were randomized into a normal group， a model group， low-dose， medium-dose， and high-dose BZ groups （BZ-L， BZ-M， BZ-H， 2.92， 5.85， 11.7 g·kg^-1）， and an estazolam （0.21 mg·kg^-1） group. Insomnia model was established on days 1 to 3. p-Chlorophenylalanine （PCPA） was injected intraperitoneally at a dose of 400 mg·kg^-1 into mice of the model group and administration groups for 3 consecutive days. Then， the classic depression model was established with chronic unpredictable mild stress （CUMS） for 28 consecutive days. Administration and modeling were performed simultaneously. After gavage， 24 h spontaneous activity test was performed to test sleep state， and sugar preference test and open field test were performed to evaluate anxiety-like state. The morphological changes of the hypothalamus were observed by hematoxylin-eosin （HE） staining， and the number of Nissl bodies was observed by Nissl staining. The ultrastructure of mitochondria was observed by transmission electron microscopy. The mitochondrial membrane potential assay kit （JC-1） was used to examine the mitochondrial function， and a biochemical assay kit was used to measure the ATP content in the hypothalamus. The level of reactive oxygen species （ROS） was determined by the immunofluorescence assay， and the serum levels of 5-hydroxytryptamine （5-HT）， noradrenalin （NE）， and cortisol （CORT） were determined by enzyme-linked immunosorbent assay （ELISA）. Western blot and Real-time quantitative polymerase chain reaction （Real-time PCR） were employed to determine the expression of PINK1， Parkin， microtubule-associated protein 1 light chain 3 （LC3）， and isolator protein 1 （p62） at protein and mRNA levels， respectively. ResultsThe 24 h spontaneous activity test showed that compared with the normal group， the model group did not exhibit circadian rhythm characteristics in their spontaneous activity time， while the circadian rhythm characteristics were restored in each treatment group （P<0.05）. The sucrose preference test indicated that compared with that in the normal group， the sucrose preference rate in the model group reduced （P<0.01）， and compared with that in the model group， the sucrose preference rate in each treatment group increased （P<0.01）. The open field test revealed that compared with the normal group， the model group exhibited decreased movement distance， average speed， frequency of visits to the central area， and time spent in the central area （P<0.01）， and compared with those in the model group， these parameters in each treatment group increased （P<0.05， P<0.01）. HE staining showed that compared with the normal group， the model group exhibited disarrangement of neurons in the hypothalamus， enlarged intercellular space， and severe nuclear condensation， while the degree of hypothalamic neuronal damage in each treatment group was alleviated. Nissl staining indicated that compared with the normal group， the model group demonstrated aggravated neuronal damage and increased damaged cells （P<0.01）. Compared with that in the model group， the number of damaged cells in each treatment group decreased （P<0.01）. Transmission electron microscopy showed that compared with the normal group， the model group exhibited mitochondrial swelling and rupture in the hypothalamus， with visible autophagic lysosomes in the cytoplasm. Compared with those in the model group， only a few autophagic lysosomes were observed in the BZ-L group， and the degree of mitochondrial swelling and rupture was alleviated in the other treatment groups. ROS immunofluorescence assay showed that compared with the normal group， the model group displayed enhanced red fluorescence intensity of mitochondrial ROS （P<0.01）， which was attenuated in each treatment group （P<0.01）. Mitochondrial membrane potential assay showed that compared with the normal group， the model group had declined mitochondrial membrane potential （P<0.01）， which was recovered in each treatment group （P<0.05， P<0.01）. The biochemical assay of ATP levels indicated that compared with the normal group， the model group exhibited decreased ATP content （P<0.01）， which rebound in each treatment group （P<0.05， P<0.01）. ELISA showed that compared with the normal group， the model group exhibited decreased 5-HT content and increased NE and CORT content （P<0.01）. Compared with the model group， each treatment group showed increased 5-HT content （P<0.01） and reduced NE content （P<0.01） and CORT content （P<0.05， P<0.01）. Western blot of the hypothalamus showed that compared with the normal group， the model group exhibited downregulated protein levels of PINK1， Parkin， and LC3 （P<0.01） and upregulated protein level of p62 （P<0.01）. Compared with the model group， each treatment group showed upregulated protein levels of PINK1， Parkin， and LC3 （P<0.05， P<0.01） and downregulated protein level of p62 （P<0.05， P<0.01）. Real-time PCR showed that compared with the normal group， the model group exhibited downregulated mRNA levels of PINK1， Parkin， and LC3 （P<0.01） and upregulated mRNA level of p62 （P<0.01）. Compared with the model group， each treatment group showed upregulated mRNA levels of PINK1， Parkin， and LC3 （P<0.01） and downregulated mRNA level of p62 （P<0.01）. ConclusionBZ can ameliorate the insomnia and anxiety state of mice by regulating PINK1/Parkin signaling pathway to improve the mitochondrial function， enhance mitochondrial autophagy， protect neurons， and repair damaged nerve cells.

SoxR, one of bacterial transcriptional regulators, plays a crucial role in bacterial responses to oxidative stress induced by unfavorable environmental conditions. So far, the understanding of bacterial responses to oxidative stress mainly stems from a handful model bacteria such as Escherichia coli and the studies on non-model bacterial responses to oxidative stress are limited. In this study, Citrobacter braakii JPG1, a commonly occurring strain of enterobacteria, was used as a model for the first time to explore the role of SoxR in the responses to aerobic/anaerobic-menadione stress. First, we analyzed the phylogenetic relationship of SoxR based on the whole genome and constructed the soxR-deleted strain (ΔsoxR). Then, the cell counts of the wild type (WT) and ΔsoxR were compared under aerobic/anaerobic-menadione stress. The results showed that the cell count of WT exposed to the aerobic-low concentration menadione (0.1 mmol/L) stress for 24 h increased by 4.2 times compared with that at the time point of 0 h, while that of ΔsoxR only increased by 1.3 times. The vast majority of WT and ΔsoxR cells died after exposure to the aerobic-high concentration menadione (0.3 mmol/L) stress for 24 h, with the cell counts only 29% and 0.2% of those at the time point of 0 h, respectively. Interestingly, the cell counts of WT showed no significant difference between the anaerobic-menadione stress and the control (P > 0.05), and the same was true for ΔsoxR. All these results indicated that SoxR of C. braakii JPG1 only has a regulatory effect on the redox cycling compound menadione under aerobic conditions and enhance the antioxidant capacity. Under anaerobic conditions, menadione failed to activate SoxR. The findings from this study provide new insights into understanding both the physiological responses to menadione stress and the regulatory role of SoxR under different oxygen conditions.

Objective To investigate the effect and mechanism of miR-155-5p targeting suppressor of cytokine signaling 1(SOCS1)in regulating the Janus kinase 2(JAK2)/signal transducer and activator of transcrip-tion 3(STAT3)signaling pathway in renal injury associated with lupus nephritis(LN).Methods Thirty female MRL-faslpr lupus model mice were randomly divided into five groups(n=6 per group):the model group,the antagomir NC group,the miR-155-5p antagomir group,the miR-155-5p antagomir+shRNA control group,and the miR-155-5p antagomir+SOCS1 shRNA group.The mice were treated with adeno-associated virus vectors carrying miR-155-5p antagomir,antagomir NC,SOCS1 shRNA,or shRNA control.Additionally,six age-matched C57BL/6 mice served as a control group and received an equivalent volume of saline.Serum blood urea nitrogen(BUN)and creatinine(Scr)levels,renal histopathological changes,and the expression levels of miR-155-5p,SOCS1,phosphorylated JAK2(p-JAK2),and phosphorylated STAT3(p-STAT3)in renal tissues were evaluated.Results Compared with the normal group,the model group exhibited significantly elevated levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins in the kidneys(P<0.01),while the expression level of SOCS1 was markedly reduced(P<0.01).Compared with both the model group and the antagomir NC group,the miR-155-5p antagomir group showed decreased levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins(P<0.01),along with a significant increase in SOCS1 expression(P<0.01).Similarly,compared with the miR-155-5p antagomir group and the miR-155-5p antagomir+shRNA control group,the miR-155-5p antagomir+SOCS1 shRNA group demon-strated significantly higher levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins(P<0.01),while SOCS1 expression was notably decreased(P<0.01).Renal pathology analysis revealed that,compared to the normal group,the model group exhibited glomerular atrophy,extensive infiltration of inflammatory cells in the renal tubulointerstitial region,and partial renal tubular necrosis.In contrast,the miR-155-5p antagomir group showed marked improvements in glomerular atrophy,tubular necrosis,and inflammatory cell infiltration compared with the model group and antagomir NC group.Furthermore,compared with the miR-155-5p antagomir group and the miR-155-5p antagomir+shRNA control group,the miR-155-5p antagomir+SOCS1 shRNA group exhibited more severe glomerular atrophy,tubular necrosis,and inflammatory cell infiltration.Conclusion MiR-155-5p exacerbates renal damage in MRL-faslpr lupus model mice by targeting SOCS1,potentially through the activation of the JAK2/STAT3 signaling pathway.

BACKGROUND: Heavy metals are significant risk factors for kidney function. Numerous studies have shown that exposure to heavy metals negatively correlates with kidney function through oxidative stress pathways, and serum α-klotho is linked to oxidative stress. However, the role of α-klotho in the relationship between blood lead, mercury, and kidney function remains unclear. METHOD: This study evaluated the mediating role of alpha-klotho in the relationship between lead, mercury and renal function, using data from the 2007-2016 National Health and Nutrition Examination Survey (NHANES) in U.S. adults aged 40-79. The sample included 11,032 participants, with blood lead, mercury, α-klotho, and other relevant covariates measured. Inductively coupled plasma mass spectrometry was used to assess blood lead and mercury levels, and enzyme-linked immunosorbent assay (ELISA) was employed to measure serum α-klotho. Kidney function was evaluated using estimated glomerular filtration rate (eGFR) based on creatinine levels. Multivariable linear regression was conducted to analyze the relationships between blood lead, mercury, α-klotho, and eGFR. A mediation analysis model was used to assess whether α-klotho influenced these associations. RESULTS: We observed a significant association between blood lead and eGFR. Mediation analysis revealed that α-klotho accounted for 12.76% of the relationship between serum lead and eGFR in the NHANES population. Subgroup analysis showed that α-klotho mediated 12.43%, 6.87%, 21.50% and 5.44% of the relationship between blood lead and eGFR in women, middle-aged adults (40-59 years old), without cardiovascular disease and hypertension, respectively. However, α-klotho did not mediate the relationship between blood mercury and eGFR in terms of gender or age. This newly identified pathway may provide valuable insights for the prevention and treatment mechanisms related to kidney function impairment. CONCLUSION We found that blood lead was associated with renal function. According to the results of subgroup analysis, for blood lead, serum α-klotho mediated the association in females, middle aged 60-79 years. The relationship between blood mercury and renal function was not clinically significant, and serum α-Klotho mediated the relationship between blood mercury and renal function without significant clinical significance.

Objective: To observe and compare the clinical effects of different electroacupuncture waveforms on primary dysmenorrhea. Methods: This was a prospective, randomized, three-group, parallel-controlled trial. Participants with primary dysmenorrhea were randomly divided into dense-sparse wave, continuous wave, and discontinuous wave groups in a 1:1:1 ratio. Two lateral Ciliao (BL 32) points were used. All three groups started treatment 3–5 days before menstruation, once a day for six sessions per course of treatment, one course of treatment per menstrual cycle, and three menstrual cycles. The primary outcome measure was the proportion with an average visual analog scale (VAS) score reduction of ≥50% from baseline for dysmenorrhea in the third menstrual cycle during treatment. The secondary outcome measures included changes in dysmenorrhea VAS scores, Cox Menstrual Symptom Scale scores and the proportion of patients taking analgesic drugs. Results: The proportion of cases where the average VAS score for dysmenorrhea decreased by ≥50% from baseline in the third menstrual cycle was not statistically significant (P > .05). Precisely 30 min after acupuncture and regarding immediate analgesia on the most severe day of dysmenorrhea, there was a statistically significant difference in the dense-sparse wave group compared with the other two groups during the third menstrual cycle (P < .05). Additionally, there was a statistically significant difference between the dense-sparse wave and discontinuous wave groups 24 h after acupuncture (P < .05). Conclusions Waveform electroacupuncture can alleviate primary dysmenorrhea and its related symptoms in patients. The three groups showed similar results in terms of short- and long-term analgesic efficacy and a reduction in the number of patients taking analgesic drugs. Regarding achieving immediate analgesia, the dense-sparse wave group was slightly better than the other two groups.

[Objective]To explore the medication rule of TCM compound patent in the treatment of gout,and analyze the mechanism of action of the core herbs based on the national patent database.[Methods]The Chinese herbal compound patent database for gout treatment was retrieved and entered into the Website of China Patent Announcement of The State Intellectual Property Office.The characteristics of medications were analyzed by frequency statistics,Apriori algorithm,factor analysis and systematic clustering method.The Chinese herbs targets of the core herbs combinations were obtained through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and the gout disease targets were obtained from Human Gene database(GeneCards)and Online Mendelian Inheritance in Man(OMIM)database.The intersection of the two targets was imported into Cytoscape 3.9.1 software,and the Cluego plug-in was used to complete the Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis of the herb combinations.The intersection targets were imported into STRING database to obtain protein-protein interaction(PPI)network,and some key targets were selected for molecular docking with corresponding active compounds of Chinese herbs.[Results]A total of 508 Chinese herbal compound patents were included in the treatment of gout,involving 401 Chinese herbs,and the frequency of herbs was 6 082 times.Chinese herbs for diuresis-inducing and dampness-draining were mainly used,followed by herbs for tonifying deficiency,clearing heat,promoting blood circulation and removing blood stasis.The analysis of association rules obtained 3 binomial association rules and 5 trinomial association rules.Eight common factors were extracted by factor analysis.Three groups of herbs combinations were obtained by systematic clustering analysis,and 56 common biological pathways of herbs combination enrichment were found.Molecular docking results showed that the combination of Quercetin and tumor necrosis factor(TNF)was the best,followed by Baicalein and interleukin-6(IL-6),and the combination of Quercetin and adenosine triphosphate binding cassette super family G member 2(ABCG2)was good.[Conclusion]The national patent prescriptions for gout treatment based on the core pathogenesis of"turbid dampness and blood stasis"are mainly from three aspects of dampness,blood stasis and deficiency.The core herbs combinations are often supplemented or subtracted based on Simiao Powder,Fuling Zexie Decoction and Siwu Decoction.Chinese herbs mainly exert their effects through multiple signaling pathways such as TNF,hypoxia inducible factor-1(HIF-1),Toll-like receptors(TLRs)and IL-17 and promote excretion of uric acid.

Objective Taking Sortilin as the entry point,this study aims to explore the mechanism of vascular calcification in chronic renal failure(CRF)and explore the influence of Sanqi on Sortilin,TLRs and vascular calcification,and to provide an effective method for clinical reduction of cardiovascular events in CRF.Methods Thirty-six male SD rats were randomly divided into normal group,model group,low-,medium-and high-dose Sanqi group and calcitriol group,with 6 rats in each.The replicative CRF vascular calcification rat model was fed with adenine combined with high phosphorus diet.Aortic calcium salt deposition,serum creatinine(Scr),urea nitrogen(BUN),blood calcium(Ca),blood phosphorus(P),total cholesterol(TC),triglyceride(TG),TLRs and Sortilin protein in aorta and inflammatory factors were detected.Results In the model group,renal fibrosis was obvious and many adenine crystals were found in renal interstitium.Large deposits of calcium salts were found.Renal fibrosis and calcium salt deposition were alleviated in different degrees in all treatment groups.Compared with those in the normal group,the level of BUN,Cr,P,TG,TC,IFN-γ,IL-6,IL-10 and IL-17A in the serum of the model group was ascended(P<0.01),while the level of Ca was descended(P<0.01).Compared with those in the model group,the level of BUN,Cr,P,TG,TC,IFN-γ,IL-6,IL-10 and IL-17A in the serum of rats in the Sanqi medium and high dose group and calcitriol group was significantly decreased(P<0.01),and the contents of Ca were significantly increased(P<0.05 or P<0.01).Compared with those in the normal group,the protein expression of BMP2,RUNX2,Sortilin,TLR7 and TLR9 in aortic tissue of rats in the model group was elevated(P<0.01),while the protein expression of SM22α was declined(P<0.01).Compared with those in the model group,the protein expression of BMP2,RUNX2,Sortilin,TLR7,and TLR9 in the low-,medium-,and high-dose Sanqi group and calcitriol group was decreased significantly(P<0.01);the protein expression of SM22α was increased significantly(P<0.05 or P<0.01),and the high-dose Sanqi group and calcitriol group had more significant effects.Conclusion Sanqi can improve renal fibrosis and vascular calcification in CRF model rats,and its mechanism may be related to the regulation of biological functions of Sortilin and TLRs.
