ObjectiveTo investigate the intervention effects of Suanzaoren Tang on depression model rats induced by isolation combined with chronic unpredictable mild stress (CUMS), and to examine its influence on the c-Jun N-terminal kinase (JNK)/proto-oncogene protein (c-Myc)/tumor suppressor protein 53 (p53) signaling pathway, thereby revealing its potential functional mechanism. MethodsA total of 72 male SD rats were randomly divided into six groups using a strict random number table: blank group, model group, fluoxetine group (3.6 mg·kg-1), and high-, medium-, and low-dose Suanzaoren Tang groups (10, 5, 2.5 g·kg-1),with 12 rats in each group. A depression model was established using isolation combined with CUMS. Fluoxetine and different doses of Suanzaoren Tang were administered continuously for 28 days. Behavioral indicators such as sucrose water consumption and open field test scores were recorded. Western blot and immunohistochemistry (IHC) were employed to analyze the expression of key proteins in the JNK/c-Myc/p53 signaling pathway, and the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to evaluate the number of apoptotic cells in the hippocampus. ResultsCompared with the blank group, the model group exhibited a significantly reduced sucrose preference index (P<0.01), a lower total score of horizontal and vertical movements in the open field test (P<0.01), significantly increased expression of JNK, c-Myc, and p53 proteins in the hippocampus (P<0.01), and a higher number of TUNEL-positive cells in the hippocampus (P<0.01). Compared with the model group, the sucrose preference index and the total score of horizontal and vertical movements in the open field test significantly increased in the high- and medium-dose Suanzaoren Tang groups and the fluoxetine group (P<0.05, P<0.01). The expression of JNK, c-Myc, and p53 proteins significantly decreased in all Suanzaoren Tang groups (high, medium, and low doses) and the fluoxetine group (P<0.05, P<0.01). The number of TUNEL-positive cells in the hippocampus also significantly decreased in these groups (P<0.01). ConclusionSuanzaoren Tang can regulate the expression of JNK/c-Myc/p53 proteins in the hippocampus of depression model rats, and its antidepressant mechanism may be related to its protective effect on hippocampal neurons.

Objective: To investigate the influencing factors of overactive bladder (OAB) in college freshmen and the impacts of OAB on their mental health, quality of life and social interaction. Methods: An epidemiological questionnaire survey was conducted in an anonymous manner on the prevalence of OAB among 5300 freshmen aged 17 to 22 years enrolled in the 2023—2024 academic year in Xinxiang Medical University and Sanquan College of Xinxiang Medical University.The questionnaire included questions on basic information, history of urinary tract infection, constipation, smoking, history of alcohol consumption, history of coffee/strong tea drinking, history of carbonated beverage drinking, redundant prepuce, phimosis, holding urine, chronic insomnia, self-rating anxiety scale (SAS), quality of life score (QoL), and social avoidance and distress scale (SADS).The influencing factors of OAB were analyzed with multivariate logistic regression analysis.The subjects were grouped according to whether they had OAB, and the differences in SAS, QoL and SADS between the OAB group and non-OAB group were compared.The impacts of OAB on the anxiety level, quality of life, and social interaction were analyzed with multiple linear regression analysis. Results: The overall prevalence rate of OAB was 4.9% (244/5018).Multivariate logistic regression analysis showed that the history of urinary tract infection (OR=0.177), constipation (OR=0.636), smoking (OR=0.582), alcohol consumption (OR=0.685), coffee/strong tea drinking (OR=0.387), carbonated beverage drinking (OR=0.631), redundant prepuce (OR=0.673), phimosis (OR=0.311), urine holding (OR=0.593), and chronic insomnia (OR=0.256) were influencing factors for the occurrence of OAB (P<0.05).The OAB group had higher SAS score [(41.18±6.54) vs. (38.61±6.36)], QoL score [(3.65±1.20) vs. (2.79±0.95)], social avoidance score [(6.25±1.86) vs. (5.86±1.51)], social distress score [(6.27±1.59) vs. (5.97±1.32)], and total SADS score [(12.51±2.35) vs. (11.84±2.01)] than the non-OAB group (P<0.05).The results of multiple linear regression analysis showed that OAB could independently affect the scores of QoL, SAS, and SADS.The OAB group had higher scores of QoL, SAS, and SADS compared with the non-OAB group (P<0.001). Conclusion: History of urinary tract infection, constipation, smoking, alcohol consumption, coffee/strong tea drinking, carbonated beverage drinking, redundant prepuce, phimosis, urine holding, and chronic insomnia are influencing factors for the occurrence of OAB in male college students.Moreover, OAB has negative impacts on their mental health, quality of life, and social interaction.

ObjectiveTo explore the effects of Renshentang on atherosclerosis (AS) in mice based on the role of transient receptor potential vanilloid1 (TRPV1) in regulating cholesterol metabolism in foam cells. MethodsNine SPF-grade 8-week-old C57BL/6J mice were set as a normal group, and 60 ApoE-/- mice were randomized into model, positive drug (simvastatin, 0.02 g·kg-1·d-1), and low-, medium-, and high-dose (1.77, 3.54, 7.08 g·kg-1·d-1, respectively) Renshentang groups (n=12) according to body weight. The normal group was fed with a normal diet, and the other groups were fed with a high-fat diet and given corresponding drugs by oral gavage for the modeling of AS. The mice were administrated with corresponding drugs once a day for 12 weeks. After the last administration and fasting for 12 h, the aorta was collected. Plaque conditions, pathological changes, levels of total cholesterol (TC), triglcerides (TG), low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C), and the expression of TRPV1, liver X receptor (LXR), inducible degrader of the low-density lipoprotein receptor (IDOL), and low-density lipoprotein receptor (LDLR) in the aortic tissue were observed and detected by gross oil red O staining, HE staining, Western blot, immunohistochemistry, and real-time PCR. ResultsCompared with the normal group, the model group presented obvious plaque deposition in the aorta, raised levels of TC, TG, and LDL-C in the serum (P<0.01), up-regulated expression level of LDLR in the aorta (P<0.01), lowered level of HDL-C in the serum, and down-regulated expression levels of TRPV1, LXR, and IDOL in the aorta (P<0.05, P<0.01). Compared with the model group, the positive drug and Renshentang at different doses alleviated AS, elevated the levels of HDL-C, TRPV1, LXR, and IDOL (P<0.05, P<0.01), while lowering the levels of TC, TG, LDL-C, and LDLR (P<0.05, P<0.01). ConclusionRenshentang has a lipid-lowering effect on AS mice. It can effectively reduce lipid deposition, lipid levels, and plaque area of AS mice by activating TRPV1 expression and regulating the LXR/IDOL/LDLR pathway.

This paper explored the specific mechanism of ginsenoside Rg_1 in regulating mitochondrial fusion through the neurogenic gene Notch homologous protein 1(Notch1) pathway to alleviate hypoxia/reoxygenation(H/R) injury in HL-1 cells. The relative viability of HL-1 cells after six hours of hypoxia and two hours of reoxygenation was detected by cell counting kit-8(CCK-8). The lactate dehydrogenase(LDH) activity in the cell supernatant was detected by the lactate substrate method. The content of adenosine triphosphate(ATP) was detected by the luciferin method. Fluorescence probes were used to detect intracellular reactive oxygen species(Cyto-ROS) levels and mitochondrial membrane potential(ΔΨ_m). Mito-Tracker and Actin were co-imaged to detect the number of mitochondria in cells. Fluorescence quantitative polymerase chain reaction and Western blot were used to detect the mRNA and protein expression levels of Notch1, mitochondrial fusion protein 2(Mfn2), and mitochondrial fusion protein 1(Mfn1). The results showed that compared with that of the control group, the cell activity of the model group decreased, and the LDH released into the cell culture supernatant increased. The level of Cyto-ROS increased, and the content of ATP decreased. Compared with that of the model group, the cell activity of the ginsenoside Rg_1 group increased, and the LDH released into the cell culture supernatant decreased. The level of Cyto-ROS decreased, and the ATP content increased. Ginsenoside Rg_1 elevated ΔΨ_m and increased mitochondrial quantity in HL-1 cells with H/R injury and had good protection for mitochondria. After H/R injury, the mRNA and protein expression levels of Notch1 and Mfn1 decreased, while the mRNA and protein expression levels of Mfn2 increased. Ginsenoside Rg_1 increased the mRNA and protein levels of Notch1 and Mfn1, and decreased the mRNA and protein levels of Mfn2. Silencing Notch1 inhibited the action of ginsenoside Rg_1, decreased the mRNA and protein levels of Notch1 and Mfn1, and increased the mRNA and protein levels of Mfn2. In summary, ginsenoside Rg_1 regulated mitochondrial fusion through the Notch1 pathway to alleviate H/R injury in HL-1 cells.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

ObjectiveTo explore the effect and mechanism of Zhishi Xiebai Guizhitang on the progression of atherosclerosis (AS) mice based on the regulation of cholesterol metabolism in foam cells by transient receptor potential channel ankyrin 1 (TRPA1). MethodThe AS model was established on apolipoprotein E knockout (ApoE-/-) mice with a high-fat diet. The mice were randomly divided into low-dose, middle-dose, and high-dose groups of Zhishi Xiebai Guizhitang (2.97, 5.94, 11.88 g·kg-1) and simvastatin group (0.002 g·kg-1), and the drug was administered along with a high-fat diet. C57BL/6J mice were fed an ordinary diet as a normal group. After the above process, the aorta and serum of mice were taken. The pathological changes of the aortic root were observed by hematoxylin-eosin (HE) staining. The lipid plaques in the aorta were observed by gross oil redness. Serum levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were detected, and the levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were detected by enzyme-linked immunosorbent assay (ELISA). Western blot and immunohistochemical method were used to analyze the expression of TRPA1, ATP-binding cassette transporter A1 (ABCA1), ATP-binding cassette transporter G1 (ABCG1), and mannose receptor (CD206). ResultFrom the perspective of drug efficacy, compared with the normal group, pathological changes such as plaque, a large number of foam cells, and cholesterol crystals appeared in the aorta of the model group, and the serum levels of TC, LDL-C, IL-1β, and IL-18 were significantly increased (P<0.01). The HDL-C level was significantly decreased (P<0.01), and the CD206 level in aortic tissue was significantly decreased (P<0.01). Compared with the model group, the lipid deposition in the aorta was alleviated in all drug administration groups. In addition, except for the high-dose group of Zhishi Xiebai Guizhitang, all drug administration groups could significantly decrease the levels of TC and LDL-C (P<0.01). In terms of inflammation, except for the middle-dose group of Zhishi Xiebai Guizhitang, the levels of IL-1β and IL-18 were significantly decreased in all drug administration groups (P<0.05). Moreover, Zhishi Xiebai Guizhitang could also up-regulate the levels of CD206, and the difference was significant in the middle-dose and high-dose groups (P<0.05). From the perspective of mechanism, the expression levels of TRPA1, ABCA1, and ABCG1 in the aorta in the model group were lower than those in the normal group (P<0.05). Compared with the model group, all drug administration groups significantly increased the expression of TRPA1 in the aorta (P<0.05), and the expressions of ABCA1 and ABCG1 were increased. The differences in the middle-dose and high-dose groups and the simvastatin group were significant (P<0.05), which was basically consistent with the trend of immunohistochemical results. ConclusionZhishi Xiebai Guizhitang can effectively reduce blood lipid and inflammation levels and inhibit the formation of aortic plaque. The mechanism may be explained as follows: the expressions of ABCA1 and ABCG1 downstream are increased through TRPA1, which promotes cholesterol outflow in foam cells, thereby regulating cholesterol metabolism, intervening in inflammation level to a certain extent, and finally treating AS.

ObjectiveTo observe and compare the electrocardiogram index, myocardial morphology, and connexin 43 (Cx43) expression of two rat models of acute cerebral infarction (ACI) due to stasis combined with toxin complicated with cerebral-cardiac syndrome (CCS), and to provide experimental evidence for the research on the occurrence mechanism of cardiac diseases induced by ACI and the clinical diagnosis and treatment of CCS. MethodSixty SPF-grade male SD rats were randomized into six groups (n=10): normal , syndrome of stasis combined with toxin induced by carrageenin combined with dry yeast (CA/Y), multi-infarct induced by micro-embolism (ME), middle cerebral artery occlusion (MCAO), CA/Y+ME, and CA/Y+MCAO groups. The model of syndrome of stasis combined with toxin was established by intraperitoneal injection with carrageenan (CA) at 10 mg·kg-1 on the first day and subcutaneous injection with dry yeast (Y) suspension (2 mg·kg-1) on the second day of modeling. Twenty-four hours after the modeling of ACI, the electrocardiograms (ECGs) of rats in each group were collected and the number/percentage (%) of abnormal ECG was calculated. The infarct area of the brain was evaluated by 2,3,5-triphenyltetrazolium chloride (TTC) staining, and myocardial injury was assessed by hematoxylin-eosin (HE) staining. Immumohistochemical staining and Western blot were employed to determine the expression of Cx43 in the myocardium. ResultA certain number of rats in each model group presented abnormal ECG. Compared with the normal group and CA/Y group, CA/Y+MCAO group had the highest rate of abnormal ECG (P<0.01). Compared with the normal, CA/Y, ME, and CA/Y+ME groups, the CA/Y+ME and CA/Y+MCAO groups showed decreased amplitudes of P-wave and T-wave, shortened P-R interval, and extended Q-T interval, which were particularly obvious in the CA/Y+MCAO group (P<0.05, P<0.01) and in accordance with the cerebral infarction area and pathological changes. The expression of Cx43 was up-regulated in both CA/Y+ME and CA/Y+MCAO groups, especially in the CA/Y+MCAO group (P<0.01). ConclusionThe two rat models of ACI due to stasis combined with toxin complicated with CCS can be used to study the mechanism of heart diseases caused by cerebrovascular diseases and the therapeutic effects of Chinese medicines with the functions of resolving stasis and detoxifying. Moreover, the CA/Y+MCAO method has higher abnormal electrocardiogram rate, severer myocardial pathological injury, and higher expression of Cx43 protein. The models can be chosen according to specific experimental purpose.
