Zishen Huoxue decoction (ZSHX) enhances cardiomyocyte viability following hypoxic stress; however, its upstream therapeutic targets remain unclear. Network pharmacology and RNA sequencing analyses revealed that ZSHX target genes were closely associated with mitophagy and apoptosis in the mitochondrial pathway. In vitro, ZSHX inhibited pathological mitochondrial fission following hypoxic stress, regulated FUN14 domain-containing protein 1 (FUNDC1)-related mitophagy, and increased the levels of mitophagy lysosomes and microtubule-associated protein 1 light chain 3 beta II (LC3II)/translocase of outer mitochondrial membrane 20 (TOM20) expression while inhibiting the over-activated mitochondrial unfolded protein response. Additionally, ZSHX regulated the stability of beta-tubulin through Sirtuin 5 (SIRT5) and could modulate FUNDC1-related synergistic mechanisms of mitophagy and unfolded protein response in the mitochondria (UPR^mt) via the SIRT5 and -β-tubulin axis. This targeting pathway may be crucial for cardiomyocytes to resist hypoxia. Collectively, these findings suggest that ZSHX can protect against cardiomyocyte injury via the SIRT5-β-tubulin axis, which may be associated with the synergistic protective mechanism of SIRT5-β-tubulin axis-related mitophagy and UPR^mt on cardiomyocytes.

Objective:To investigate the characteristics of hand dysfunction and its associated factors in patients with rheumatoid arthritis (RA).Methods:A cross-sectional study. Patients with RA were recruited from January 2019 to April 2024 at the Department of Rheumatology and Immunology, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. Demographic and clinical data were collected, including age, gender, active smoking, disease duration, time of morning stiffness, rheumatoid factor and anti-cyclic citrullinated peptide antibody, disease activity, radiographic indicators, and hand function assessment. Hand function was assessed by grip strength measures and self-reported items related to hand function in the Stanford Health Assessment Questionnaire. Factors related to hand function were analyzed by logistic regression analyses.Results:A total of 1 079 RA patients were recruited [mean age: (53.0±12.6) years]. Overall, 72.6% (783/1 079) patients experienced a decrease in grip strength, 57.2% (617/1 079) patients experienced a decreased grip strength in both hands, with the average grip strength of the left and right hands decreasing by 16.3% and 14.1%, respectively, compared to normal values; 39.9% (430/1 079) patients had self-reported hand dysfunction. There were 185 (17.1%) older RA patients (age ≥65 years). The proportion of older RA patients with decreased grip strength [89.7% (166/185) vs. 69.0% (617/894)] and degree of decrease in grip strength compared to normal values (left hand:-35.3%±30.6% vs. -12.3%±38.6%; right hand:-32.6%±32.3% vs. -10.3%±42.1%) were significantly higher than that in young patients, and the proportion of older patients with self-reported hand dysfunction was also significantly higher [53.0% (98/185) vs. 37.1% (332/894), all P<0.001]. Multivariate logistic regression analysis showed that pain visual analogue scale ( OR=1.375, 95% CI 1.020-1.854) was independently associated with grip strength decrease in older RA patients, while the 28-joint tender joint count ( OR=1.151, 95% CI 1.063-1.246) and provider global assessment of disease activity ( OR=1.381, 95% CI 1.171-1.628) were associated with self-reported hand dysfunction. Conclusions:Hand dysfunction is common in RA patients, especially among older RA patients, which is related to pain, joint tenderness and provider global assessment of disease activity. This result implies the importance of pain management in RA patients.

Background and Aims:Papillary thyroid carcinoma(PTC),the most common type of thyroid cancer,has been rapidly increasing in incidence worldwide,posing a serious threat to individual health and public healthcare systems.Exposure to low-to-moderate doses of ionizing radiation is more relevant to the daily lives of the general population and,therefore,raises greater public health concerns.It has also been widely recognized as a potential factor in immune system remodeling.This study was conducted to investigate the impact of low-to-moderate dose ionizing radiation on the tumor immune microenvironment of PTC,aiming to reveal the potential hazards of such radiation exposure in PTC patients.Methods:Two datasets(GSE29265 and GSE35570)containing RNA-seq data and corresponding clinical information were retrieved and downloaded from the GEO database.These datasets included thyroid cancer samples from patients exposed to ionizing radiation due to the Chernobyl disaster,as well as sporadic thyroid cancer cases.After data cleaning,merging,batch effect correction,differential gene expression analysis,functional enrichment analysis,immune cell infiltration analysis,and tumor microenvironment analysis were performed using R language.Results:In tumor samples,the radiation-exposed group exhibited significant differential gene expression compared to the sporadic group,with three genes upregulated and 27 genes downregulated.These differentially expressed genes were primarily enriched in biological functions closely related to immune responses,including chemokine activity,immune cell chemotaxis,and tumor immunity.Immune cell infiltration analysis indicated that radiation exposure had a limited impact on immune cell infiltration in normal samples.However,in tumor samples,the immune and ESTIMATE scores were significantly lower in the radiation-exposed group than in the sporadic group.Further analysis revealed that total T cells,CD4+T cells,CD8+T cells,B cells,and cytotoxic lymphocytes exhibited significantly lower infiltration levels in the tumor microenvironment of the radiation-exposed group than the sporadic group.Conclusion:Although low-to-moderate dose ionizing radiation has a relatively minor impact on normal thyroid tissue,it significantly reduces the infiltration of various immune cell subtypes in the PTC tumor microenvironment.This reduction in immune infiltration may have important implications for disease progression.

Objective To explore the nephrotoxic effects of exposure to perfluorobutanoic acid (PFBA) and its mechanism in mice, with a particular focus on analyzing the changes in kidney metabolism and their potential implications. Methods The specific pathogen free C57BL/6 mice were randomly divided into control group, low-dose group, and high-dose group, with 10 mice in each group. Mice in the three groups received intragastric administration of PFBA solution at doses of 0, 35 and 350 mg/kg body weight, once per day for seven consecutive days. The histopathological changes of kidneys of mice in these three groups were evaluated. Metabolomic profiling of mouse kidneys was performed using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Differentially accumulated metabolites (DAMs) were identified based on the Human Metabolome Database, and related metabolic pathways were analyzed through MetaboAnalyst 6.0 and Kyoto Encyclopedia of Genes and Genomes (KEGG). Results Histopathological analysis of kidneys showed that the renal pelvis mucosa of mice in the low-dose group presented focal mild inflammatory changes without marked structural damage, whereas mice in the high-dose group showed severe inflammation and partial destruction of renal structure. The kidney coefficient of mice in both low-dose group and the high-dose group decreased (both P<0.05), and the Paller scores of renal tissues increased (both P<0.05) compared with that in the control group. The Paller score of mouse renal tissue in the high-dose group was higher than that in the low-dose group (P<0.05). Metabolomic profiling identified 46 DAMs (26 upregulated, 20 downregulated) in the low-dose group and 104 DAMs (54 upregulated, 50 downregulated) in the high-dose group, with 26 shared DAMs between the two dose groups. KEGG pathway analysis revealed that DAMs were mainly involved in metabolic pathways such as glycerophospholipid metabolism, glycerolipid metabolism, sphingolipid and steroid hormone synthesis. Conclusion Acute exposure to PFBA can cause kidney injury in mice. Lipid metabolism pathways such as glycerophospholipid and sphingolipid metabolism is involved in the development of acute renal toxicity of PFBA.

OBJECTIVE To explore the relationship between white matter damage and sleepiness,decreased sleep quality,and cognitive decline in patients with OSA.METHODS There were 55 confirmed cases of OSA diagnosed by polysomnography(PSG)from January 2018 to May 2023 were selected,with 29 non-OSA controls also diagnosed by PSG.DKI scanning and Epworth sleepiness scale(ESS),Pittsburgh sleep quality index(PSQI),and Montreal cognitive assessment(MoCA)scores were performed for all subjects.Differences in kurtosis fractional anisotropy(KFA)of various brain regions were compared between the two groups to identify differential brain regions,and pairwise correlations were analyzed between KFA reduction and apnea-hypopnea index(AHI),lowest oxygen saturation(LSaO2)and various scale scores in OSA patients.RESULTS The KFA values in right external capsule,bilateral corona radiata,bilateral superior longitudinal fasciculus,corpus callosum,posterior cingulate gyrus of OSA group were lower than control group(P<0.05).For the OSA group:The correlation between ESS scores and KFA values of right posterior corona radiata,left superior longitudinal fasciculus,body of corpus callosum,splenium of corpus callosum are all negative(r=-0.287,-0.286,-0.276,-0.449,P<0.05).The correlation between PSQI scores and KFA values of right posterior corona radiata,left posterior corona radiata,splenium of corpus callosum are all negative(r=-0.390,-0.274,-0.348,P<0.05).The correlation between MoCA scores and KFA values of right posterior corona radiata,right superior longitudinal fasciculus,left anterior corona radiata,left posterior corona radiata,left superior corona radiata,left superior longitudinal fasciculus,genu of corpus callosum,body of corpus callosum,are all positive(r=0.290,0.389,0.298,0.278,0.340,0.473,0.344,0.344,P<0.05).The correlation between visuospatial and executive function scores and AHI,LSaO2,ESS scores and KFA values of right posterior corona radiata,left superior corona radiata,left superior longitudinal fasciculus and splenium of corpus callosum are all significant(r=-0.350,0.470,-0.343,0.401,0.284,0.387,0.274,P<0.05).CONCLUSION Patients with OSA exhibit damage to the white matter in certain brain regions.The damage to the corpus callosum,posterior corona radiata,and superior longitudinal fasciculus has the greatest impact on patients'sleepiness,reduced sleep quality,and cognitive impairment.In particular,the impairment in visuospatial and executive function is closely associated with white matter damage in the corona radiata and superior longitudinal fasciculus.

Objective To explore the distribution of circuit-qi indicators at birth in the patients with chronic atrophic gastritis(CAG)based on five-circuit and six-qitheory,and to summarize their congenital circuit-qi endowment features,so as to explore treatment strategies for CAG accordingly.Methods From January 2018 to December 2023,a total of 2 046 cases of patients with CAG admitted to Shenzhen Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(i.e.,Shenzhen Bao'an Traditional Chinese Medicine Hospital)were selected,and the distribution of the five-circuit and six-qiindicators at birth in the patients was analyzed by using the SPSS 24.0 statistical software.The features of the congenital circuit-qi endowment were summarized,and then the corresponding treatment strategies were put forward.Results The CAG patients had the highest proportions of circuit-qiendowment features at birth,showing as the yearly circuit being deficiency fire circuit,the dominant circuit being metal circuit,the dominant qibeing yangmingdryness-gold,the guest qibeing taiyangcold-water,and sitianbeing shaoyangminister fire and zaiquanbeing j ueyinwind-wood,and the differences in the distribution of the dominant circuit,dominant qi,and guest qiwere statistically significant(P<0.05 or P<0.01),but differences in the distribution of the yearly circuit and sitian/zaiquanwere not statistically significant(P>0.05).The analysis of the combined circuit-qifeatures at birth showed that the proportion of patients with CAG born in the year of celestial restriction,mildly-rebellious year and disharmony year was the highest,and the proportion of those born in the convergent year and iso-convergent year was the lowest,with statistically significant differences(P<0.05).Conclusion The congenital circuit-qiendowment of patients with CAG is characterized by liver depression and qistagnation,dryness and coldness.Therefore,the treatment for CAG should be from the perspective of the liver,with the method of soothing liver and harmonizing stomach,supplemented by nourishing yin to moisten dryness,and protecting yang qiof the spleen and stomach.The combined use of acup-moxibustion and Chinese medicines is recommended.

Objective To conduct preliminary evaluation of the reliability and safety of pancreatic duct-to-jejunum stent-bridging internal drainage as a supplementary approach to pancreaticojejunostomy in central pancreatectomy.Methods The clinical data of 28 patients who underwent robotic central pancreatectomy performed by our team between January 2021 and November 2024 were retrospectively collected,and and follow-up of postoperative endocrine and exocrine functions was performed.Based on the methods of digestive tract reconstruction adopted,the patients were divided into a conventional pancreaticojejunostomy group and a pancreatic duct-to-jejunum stent-bridging internal drainage group(PancreaticoJejunal-Stent bridge group).The operative time,digestive tract reconstruction time,and short-term complications were compared between the two groups.Results Among patients undergoing robotic central pancreatectomy,the digestive tract reconstruction time was shorter(t=5.168,P<0.001)in the PancreaticoJejunal-Stent bridge group([31.1±6.3]min)than that in the conventional pancreaticojejunostomy group([49.7±8.9]min)(t=5.168,P<0.001).The total operative time was(172.7±64.6)min in the PancreaticoJejunal-Stent bridge group and(200.1±52.7)min in the conventional pancreaticojejunostomy group,showing no statistically significant difference(t=1.215,P=0.235).In the PancreaticoJejunal-Stent bridge group,one patient developed a postoperative biochemical fistula,and 14 patients developed grade B pancreatic fistulas.Among the 14 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 13 cases had drainage tube retention time of more than 21 days.In the conventional pancreaticojejunostomy group,2 patients developed postoperative biochemical fistulas,and 11 patients developed grade B pancreatic fistulas.Among the 11 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 1 case was complicated by fistula-related intra-abdominal bleeding and infection.No postoperative gastroparesis,pancreatitis,or grade C pancreatic fistulas occurred in either group.There were no statistically significant differences between the two groups in overall postoperative complication rate(P=0.522),postoperative pancreatic fistula rate(P=0.583),intra-abdominal infection rate(P=0.583),or bleeding rate(P=0.464).Conclusion Pancreatic duct-to-jejunum stent-bridging internal drainage optimizes the anastomosis between the distal end of the pancreas and the jejunum during central pancreatectomy,shortens digestive tract reconstruction time,and reduces surgical complexity without increasing the risk of short-term severe postoperative complications.This approach is safe and feasible.
