BackgroundAlcohol dependence patients are prone to relapse after their attempts to quit drinking， which poses a considerable threat to their physical and mental health and creates a heavy burden on their families. Currently， empowerment education is increasingly being utilized in the rehabilitation management of chronic diseases， but there remains a striking lack of empirical research on the application of "Internet +" empowerment education based on timing it right in alcohol dependence patients. ObjectiveTo explore the impact of "Internet +" empowerment education based on timing it right on patients with alcohol dependence， in order to maximize the reduction in relapse rates， craving for alcohol and severity of anxiety symptoms. MethodsA total of 120 patients who were hospitalized in the Department of Addiction Medicine， Hebei Provincial Mental Health Center from May 2022 to April 2023 and met the diagnostic criteria for alcohol dependence in the International Classification of Diseases， tenth edition （ICD-10） were enrolled， and they were classified into study group （n=62） and control group （n=58） using random number table methods. Both groups received standard medication and routine care. Additionally， study group underwent a 6-month "Internet +" empowerment education based on timing it right. At baseline， all subjects were assessed using Penn Alcohol Craving Scale （PACS） and Self-rating Anxiety Scale （SAS）. Three months and six months after intervention， assessments were conducted using PACS， SAS and Michigan Alcoholism Screening Test （MAST）. ResultsThe relapse rates after three and six months of intervention were both lower in study group than those in control group， with statistically significant differences （χ²=8.575， 8.828， P<0.01）. ANOVA with repeated measures on PACS total score and scores of each item revealed a significant time effect， group effect and time×group interaction effect （F=159.714~837.751， 84.645~393.606， 24.302~137.896， P<0.01）. And significant time effect， group effect and time×group interaction effect were also reported on SAS scores （F=166.237， 65.325， 24.724， P<0.01）. Conclusion"Internet +" empowerment education based on timing it right may help reduce relapse rates， alcohol cravings and severity of anxiety symptoms among patients with alcohol dependence. ［Funded by 2023 Annual Hebei Provincial Medical Scientific Research Project Plan （number， 20231537）］

Panvascular disease， with vascular diseases as the common pathological feature， is mainly manifested as atherosclerosis. Panvascular disease mainly affects the important organs of the heart， brain， kidney， and limbs. It is one of the leading causes of death for Chinese residents at present. Previously， due to the narrow branches of disciplines， too much attention was paid to local lesions， resulting in the neglect of panvascular disease as a systemic one. The fact that panvascular disease has overall pathology and comprehensive and individualized treatment strategies， makes the disease highly compatible with the principles of holism concept and syndrome differentiation and treatment in traditional Chinese medicine （TCM）. It is believed that blood stasis is the core pathogenesis of atherosclerosis and is involved in the whole process of atherosclerosis. The theories of ''blood vessel''， ''meridians''， ''visceral manifestation''， and ''organs-meridians'' in TCM are helpful to comprehensively understand the complexity of panvascular diseases. Moreover， those theories can provide systematic treatment strategies. The TCM syndromes of panvascular diseases evolve from ''phlegm， stasis， stagnation， and deficiency''. Panvascular arteriosclerosis is related to the syndrome of ''stasis and phlegm''， and the treatment mainly promotes blood circulation and removes phlegm. There are different specific drugs and mechanisms of action for coronary atherosclerosis， cerebral atherosclerosis， and renal artery atherosclerotic stenosis. Panvascular venous lesions are related to the syndrome of ''deficiency and stasis'' in TCM， and the TCM treatment mainly invigorates Qi and promotes blood circulation， which can inhibit venous thrombosis， improve venous ulcers， and resist venous endothelial damage. Panvascular microcirculatory lesions are inseparable from the ''stagnation and stasis'' in TCM， and the treatment mainly promotes Qi and dredges collaterals， which has a good effect on coronary microvascular lesions， diabetic microvascular lesions， pulmonary microvascular lesions， and pancreatic microvascular lesions. Panvascular lymphatic lesions are related to the syndrome of ''water and stasis'' in TCM. The treatment method focuses on promoting blood circulation and water excretion， which can promote lymphangiogenesis and enhance lymphatic reflux. In addition， the combination of TCM and modern technology， especially the application of artificial intelligence， can improve the efficiency of early identification and personalized treatment， resulting in early screening and comprehensive management of panvascular diseases. Therefore， TCM will play a vital role in the prevention and treatment of panvascular diseases.

Background Metals and metalloids in fine particulate matter (PM_2.5) may cause damage to the respiratory and circulatory systems of the human body, and long-term exposure is prone to causing chronic poisoning, cancer, and other adverse effects. Objective To assess the distribution characteristics of metals and metalloids in outdoor PM_2.5 in a southern city of China, conduct source apportionment, and evaluate the associated health risks, thereby providing theoretical support for further pollution control measures. Methods PM_2.5 samples were collected in districts A, B, and C of a southern China city, and the concentrations of 17 metals and metalloids were detected by inductively coupled plasma-mass spectrometry (ICP-MS). Pollution sources were assessed through enrichment factor and principal components analysis, and the main pollution sources were quantified using absolute principal component scores-multivariate linear regression (APCS-MLR). Health risks were evaluated based on the Technical guide for environmental health risk assessment of chemical exposure (WS/T777—2021). Results The ambient air PM_2.5 concentrations in the city were higher in winter and spring, and lower in summer and autumn. The annual average concentrations of ambient PM_2.5 in districts A, B, and C were 36.7, 31.9, and 24.4 μg·m⁻³, respectively. The ambient PM_2.5 levels in districts B and C were below the second-grade limit set by the Ambient air quality standards (GB 3095—2012). The enrichment factors of cadmium (Cd), aluminum (Al), and antimony (Sb) were greater than 10, those of copper (Cu), lead (Pb), arsenic (As), nickel (Ni), mercury (Hg), and molybdenum (Mo) fell between 1 and 10, and those of manganese (Mn), vanadium (V), chromium (Cr), cobalt (Co), barium (Ba), beryllium (Be), and uranium (U) were below or equal to 1. The comprehensive evaluation of source analysis showed that the main pollution sources in districts A and C and the whole city were coal-burning. In district B, the main pollution source was also coal combustion, followed by industrial process sources and dust sources. The carcinogenic risks of As and Cr were between 1×10⁻⁶ and 1×10⁻⁴. However, the hazard quotients for 15 metals and metalloids in terms of non-carcinogenic risk were below 1. Conclusion Cr and As in the atmospheric PM_2.5 of the city present a certain risk of cancer and should be paid attention to. In addition, preventive control measures should be taken against relevant pollution sources such as industrial emission, dust, and coal burning.

[Objective] To study on the genotyping of a sample with inconsistent forward and reverse serological tests, and to conduct a pedigree investigation and molecular biological mechanism study. [Methods] The ABO blood group of the proband and his family members were identified using blood group serological method. The ABO gene exon 1-7 of samples of the proband and his family were sequenced by Sanger and single molecule real-time sequencing (SMRT). DeepTMHMM was used to predict and analyze the transmembrane region of proteins before and after mutation. [Results] The proband and his mother have the Bw phenotype, while his maternal grandfather has ABw phenotype. The blood group results of forward and reverse typing of other family members were consistent. ABO gene sequencing results showed that there was B new mutation of c.3 G>C in exon 1 of ABO gene in the proband, his mother and grandfather, leading to a shift in translation start site. DeepTMHMM analysis indicated that the shift in the translation start site altered the protein topology. [Conclusion] The c.3G>C mutation in the first exon of the ABO gene leads to a shift in the translation start site, altering the protein topology from an α-transmembrane region to a spherical signaling peptide, reducing enzyme activity and resulting in the Bw serological phenotype.

Zhishi Shaoyaosan is the 34^th prescription in the Catalogue of Ancient Classic Formulas （Second Batch） published by the National Administration of Traditional Chinese Medicine in 2023. It is widely used in clinical practice and has a definite curative effect. However， there is currently a lack of its ancient literature analysis and textual research， and there is no corresponding Chinese patent medicine preparation. By consulting and combing the relevant ancient books of traditional Chinese medicine， this paper analyzes and conducts textual research of the origin， composition， measurement， administration， and efficacy of Zhishi Shaoyaosan. The results show that Zhishi Shaoyaosan is derived from Essentials from the Golden Cabinet written by Zhang Zhongjing in the Eastern Han Dynasty. It is mainly recorded in the name of Zhishi Shaoyaosan in the literature of the past dynasties. The prescription is composed of Aurantii Fructus Immaturus and Paeoniae Radix Alba. The processing method is stir-frying Aurantii Fructus Immaturus to scorch and using raw Paeoniae Radix Alba. The dose of the prescription recorded in the ancient books is mainly an equal amount of Aurantii Fructus Immaturus and Paeoniae Radix Alba in one square-cun spoon， taken three times a day， which is converted into a modern dose of 1.5 g each time （0.75 g Aurantii Fructus Immaturus and 0.75 g Paeoniae Radix Alba each time）. The components of the prescription are ground into powder and taken with barley porridge， three times a day. The efficacy is to break stagnated Qi， harmonize blood， and relieve restlessness and pain. It is mainly used to treat postpartum abdominal pain， acute pelvic inflammatory disease， acute cholecystitis and intestinal diseases， stroke sequelae， and other diseases. This study combs and analyzes the ancient literature recording Zhishi Shaoyaosan and clarifies the key information of the prescription， which provides a basis for promoting the research and development of its patent medicine.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

ObjectiveINF2 is a member of the formins family. Abnormal expression and regulation of INF2 have been associated with the progression of various tumors, but the expression and role of INF2 in hepatocellular carcinoma (HCC) remain unclear. HCC is a highly lethal malignant tumor. Given the limitations of traditional treatments, this study explored the expression level, clinical value and potential mechanism of INF2 in HCC in order to seek new therapeutic targets. MethodsIn this study, we used public databases to analyze the expression of INF2 in pan-cancer and HCC, as well as the impact of INF2 expression levels on HCC prognosis. Quantitative real time polymerase chain reaction (RT-qPCR), Western blot, and immunohistochemistry were used to detect the expression level of INF2 in liver cancer cells and human HCC tissues. The correlation between INF2 expression and clinical pathological features was analyzed using public databases and clinical data of human HCC samples. Subsequently, the effects of INF2 expression on the biological function and Drp1 phosphorylation of liver cancer cells were elucidated through in vitro and in vivo experiments. Finally, the predictive value and potential mechanism of INF2 in HCC were further analyzed through database and immunohistochemical experiments. ResultsINF2 is aberrantly high expression in HCC samples and the high expression of INF2 is correlated with overall survival, liver cirrhosis and pathological differentiation of HCC patients. The expression level of INF2 has certain diagnostic value in predicting the prognosis and pathological differentiation of HCC. In vivo and in vitro HCC models, upregulated expression of INF2 triggers the proliferation and migration of the HCC cell, while knockdown of INF2 could counteract this effect. INF2 in liver cancer cells may affect mitochondrial division by inducing Drp1 phosphorylation and mediate immune escape by up-regulating PD-L1 expression, thus promoting tumor progression. ConclusionINF2 is highly expressed in HCC and is associated with poor prognosis. High expression of INF2 may promote HCC progression by inducing Drp1 phosphorylation and up-regulation of PD-L1 expression, and targeting INF2 may be beneficial for HCC patients with high expression of INF2.

OBJECTIVE To investigate the effects and mechanism of asperuloside （Asp） on the pyroptosis of intestinal epithelial cells in rats with ulcerative colitis （UC）. METHODS The male SD rats were randomly divided into Control group， model group （UC group）， ASP low-dose and high-dose groups [Asp-L， Asp-H groups， Asp 35， 70 mg/（kg·d）]， ASP high-dose group+AMPK inhibitor Compound C group [Asp-H+Compound C group， Asp 70 mg/（kg·d）+Compound C 0.2 mg/（kg·d）]， with 12 rats in each group. Except for Control group， the other groups were injected with 50% ethanol （0.25 mL）+5% 2，4， 6- trinitrobenzene sulfonic acid solution （2 mL/kg） into the intestinal cavity to construct UC model. After modeling， the rats in each drug group were given corresponding drug solution by gavage or （and） tail vein injection， once a day， for 14 consecutive days. After the last administration， the weight of rats in each group was measured， and the length of their colons was measured； disease activity index （DAI） score and colonic mucosal damage index （CMDI） score were performed， and the serum levels of inflammatory factors （interleukin-18， -1β， -6） were detected. The pathological changes of the colon tissue were observed. The expressions of pyroptosis-related proteins [caspase-1， gasdermin D （GSDMD）] in colon tissue， and pathway-related proteins such as adenosine monophosphate-activated protein kinase （AMPK）， thioredoxin-interacting protein （TXNIP）， NOD-like receptor protein 3 （NLRP3） and apoptosis-associated speck-like protein containing a CARD （ASC） were all detected. RESULTS Compared with Control group， the colon tissue structure of rats in UC group was damaged， with obvious infiltration of inflammatory cells and edema. Their body weight， colon length and phosphorylation level of AMPK protein were significantly reduced or shortened； DAI and CMDI scores， serum levels of inflammatory factors， and the protein expressions of caspase-1， GSDMD， TXNIP， NLRP3 and ASC in colon tissue were increased or upregulated significantly （P＜0.05）. Compared with UC group， the pathological damage of colon tissue in rats was relieved in Asp-L and Asp-H groups， and all quantitative indicators were significantly improved （P＜0.05）； the improvement effect of Asp-H group was more significant （P＜0.05）. Compound C could significantly reverse the improvement effect of high-dose of Asp on the above indicators in UC rats （P＜0.05）. CONCLUSIONS Asp can improve inflammatory damage in colon tissue and inhibit pyroptosis of intestinal epithelial cells in UC rats， which is associated with the activation of AMPK and inhibition of TXNIP/NLRP3 signaling pathway.

[Objective] To investigate the factors influencing the detection of HLA-C expression by flow cytometry. [Methods] A total of 12 hematopoietic stem cell suspension samples from peripheral hematopoietic stem cell volunteer donors were randomly collected after CD34⁺ cell counting detection. The influence of detecting different number of nucleated cell (500 000, 50 000 and 5 000), sequential order of red blood cell lysis and antibody incubation, and the HLA-C antibody with varied remaining time from the expiration date on the detection results of HLA-C expression by flow cytometry were investigated, respectively. The significance of differences between different groups was analyzed through Student t test. [Results] There was no significant difference in the proportion of HLA-C positive cells and mean fluorescence intensity (MFI) among the three groups with different nucleated cell numbers detected (500 000, 50 000 and 5 000) (P>0.05). The sequential order of red blood cell lysis and antibody incubation had no influence on the proportion of HLA-C positive cells (P>0.05), but HLA-C MFI value was significantly lower when antibody incubation was performed after red blood cell lysis than that when antibody incubation was performed before red blood cell lysis (P<0.05). The proportion of HLA-C positive cells and MFI value detected by HLA-C antibody remaining 24 months from the expiration date were significantly higher than those detected by HLA-C antibody remaining only 5 months from the expiration date (P<0.05). [Conclusion] The present study has investigated the factors of influencing HLA-C expression level by flow cytometry, the results have important reference and application value for standardizing the experimental operation of HLA-C expression and improving the accuracy and comparability of detection results.
