Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

Myocardial fibrosis （MF）， characterized by decreased cardiac function and myocardial compliance， is a pathological process and a progression factor in various cardiovascular diseases. The nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） inflammasome is closely related to the development of MF. Recent studies have shown that traditional Chinese medicine （TCM） can regulate the NLRP3 inflammasome to alleviate MF. Based on this， this article systematically summarizes the research progress on the mechanisms by which TCM regulates the NLRP3 inflammasome to improve MF. It is found that active ingredients of TCM， such as alkaloids （lycorine，vincristine，bufalin）， saponins （astragaloside Ⅳ， diosgenin，ginsenoside Rg3）， terpenoids （celastrol，oridonin）， and phenols （polydatin，curcumin，phloridzin） as well as TCM formulas （Zhachong shisanwei pills，Zhilong huoxue tongyu capsules， Luqi formula） can inhibit the activation of the NLRP3 inflammasome， thereby suppressing the release of inflammatory factors such as interleukin-1β and IL-18， reducing inflammatory damage to myocardial tissue， alleviating excessive deposition of the extracellular matrix， and thus exerting the effect of improving MF.

Diabetic cardiomyopathy （DCM）， a cardiovascular complication caused by diabetes mellitus， is a major cause of heart failure and even sudden cardiac death in diabetic patients. Traditional Chinese medicine （TCM） posits that the core pathogenesis of DCM lies in internal deficiency and superficial excess， characterized by deficiency of both Qi and Yin combined with phlegm and blood stasis. Modern medical treatments for DCM primarily focus on blood glucose control and symptom alleviation yet lack targeted therapeutic strategies. In contrast， TCM offers a wealth of practical experience and a complete theoretical system， demonstrating definite clinical efficacy and high medication safety in DCM management. As a classic formula for tonifying Qi and nourishing Yin， Shengmaisan comprises Ginseng Radix et Rhizoma， Ophiopogonis Radix， and Schisandrae Chinensis Fructus. It contains multiple bioactive components， including ginsenosides， ophiopogonin， schisandrins， and homoisoflavonoids， which exhibit cardioprotective properties. The therapeutic mechanisms of Shengmaisan-like formulae for DCM involve enhancing myocardial contractility， attenuating myocardial fibrosis， modulating mitochondrial quality control， regulating glucose metabolism， mitigating oxidative stress， and suppressing inflammatory responses. Clinically， Shengmaisan-like formulae not only manage hyperglycemic status but also ameliorate cardiac structural and functional impairments and enhance exercise tolerance in DCM patients， playing a vital role in the prevention， treatment， and rehabilitation of DCM. This paper analyzes the feasibility of Shengmaisan-like formulae in DCM management and synthesizes current research achievements regarding their chemical components， mechanisms of action， and clinical applications， aiming to provide a scientific foundation for the use of such formulae in the treatment of DCM.

Aim To explore the role of Takeda G pro-tein-coupled receptor 5(TGR5)in the proliferation and migration of vascular smooth muscle cells(VSMCs)within the intimal layer of mice.Methods Mouse VSMCs were stimulated for proliferation and migration with PDGF-BB,followed by administration of INT-777 for activation of TGR5.CCK-8 assay and Ki-67 immunofluorescence staining were employed to eval-uate cell proliferation.The scratch assay was utilized to assess migration.Western blot analysis was conducted to monitor TGR5 protein expression.To further investi-gate the role of TGR5 in intimal hyperplasia in vivo,20 male wild-type C57BL/6J mice were randomly divided into four groups:sham group,carotid artery endothelial injury group,sham+UDCA(ursodeoxy-cholic acid,a TGR5 agonist)group,and carotid artery endothelial injury+UDCA group(n=5 in each group).After the establishment of endothelial injury model,mice were orally fed with regular maintenance feed containing 0.5％UDCA for 21 days.Subsequent-ly,samples were collected for Hematoxylin and Eosin(HE)staining to assess the neointimal hyperplasia.Immunofluorescence(IF)staining was used to exam-ine the proliferation of VSMCs within the carotid inti-ma.Results The specific activation of TGR5 marked-ly diminished cell viability,the proportion of Ki-67-positive cells,and slowed down the rate of wound-heal-ing.Notably,the specific activation of TGR5 increases the expression of UCP2 in cells and reduces the levels of reactive oxygen species(ROS).The inhibitory effect of TGR5 on VSMC proliferation and migration was neutralized upon the restoration of intracellular ROS level with H2O2.Activation of TGR5 was found to mitigate intimal thickening following carotid artery inju-ry.Conclusion TGR5 may inhibit the proliferation and migration of mouse VSMCs by attenuating intracel-lular oxidative stress.

Objective To investigate the preliminary clinical effect of closed reduction and cannulated nail internal fixa-tion for femoral neck fracture assisted by robot navigation and positioning system.Methods From July 2019 to January 2020,16 cases of femoral neck fracture(navigation group)were treated with closed reduction and internal fixation guided by robot system,including 7 males and 9 females,aged 25 to 72 years old with an average of(53.61±5.45)years old;Garden classification of fracture:3 cases of type Ⅰ,3 cases of type Ⅱ,8 cases of type Ⅲ,2 cases of type Ⅳ.Non navigation group(control group):20 cases of femoral neck fracture were treated with closed reduction and hollow nail internal fixation,8 males and 12 females,aged 46 to 70 years old with an average of(55.23±4.64)years old;Garden type Ⅰ in 2 cases,type Ⅱ in 4 cases,type Ⅲ in 11 cases,type Ⅳ in 3 cases.The operation time,fluoroscopy times,guide needle drilling times,screw adjustment times,intraoperative bleeding volume and other indicators of two groups were evaluated.Results Both groups were followed up for 12 to 18 months with an average of(15.6±2.8)months.The fractures of both groups were healed without delayed union and nonunion.There was no significant difference in healing time between two groups(P=0.782).There was no significant differ-ence in Harris scores between two groups at the last follow-up(P=0.813).There was no significant difference in operation time between two groups(P＞0.05).There were significant differences between two groups in fluoroscopy times,guide needle drilling times,hollow screw replacement times,and intraoperative bleeding volume(P＜0.05).Conclusion Closed reduction and hollow screw internal fixation assisted by robot navigation system for femoral neck fracture has the advantages of minimally invasive operation,precise screw placement,and reduction of X-ray radiation damage during operation.

Objective:To analyze the activity of lithium chloride (LiCl) against influenza virus A (H3N2) in human non-small cell lung cancer cells (A549).Methods:Different concentrations of LiCl were incubated with A549 cells, and the cytopathic effect (CPE) was observed after 24 hours, and the effect of LiCl on cell activity was determined by CCK-8 method. After H3N2 (MOI=1) infected A549 cells, different concentrations of LiCl were added and incubated for 24 hours, and the viral load was measured by real time/reverse transcription quantitative polymerase chain reaction (RT-qPCR), and the CPE was observed, and the viral titer was determined. Different concentrations of LiCl were incubated with A549 at 37 ℃ and 5% CO 2 for 2 hours, virus was added and incubated for 24 hours, and the viral load was determined by RT-qPCR. LiCl, H3N2 and A549 were incubated at 4 ℃ for 1 hour, 35 ℃, 5% CO 2 for 24 hours, and viral load was determined by RT-qPCR. H3N2 and A549 were incubated at 4 ℃for 1 hour, then different concentrations of LiCl were added, incubated at 35 ℃ with 5% CO 2 for 24 hours, and the viral load was determined by RT-qPCR. After H3N2 infected A549 cells, different concentrations of LiCl were added and incubated for 24 hours, and the viral RNA load and viral titer of the supernatant and cells were measured, respectively, and then the corresponding ratios of the supernatant and the cells were calculated. After H3N2 (MOI=10) and BV (MOI=1) infected A549 cells, different concentrations of LiCl were added for 24 h, and the viral load was determined by RT-qPCR. Results:When the concentration of LiCl was<50 mmol/L, the cell viability of A549>90%. Different concentrations of LiCl could significantly reduce the viral load of H3N2 ( P<0.000 1), and the CPE of the LiCl treatment group was more dose-dependent than that of the control group. LiCl did not inhibit viral replication by affecting the cell itself; Different concentrations of LiCl significantly inhibited the entry of H3N2 into A549 ( P<0.000 1), and also had a certain inhibitory effect on the adsorption of A549 cells ( P<0.1). LiCl did not affect the assembly and release of H3N2 ( P>0.05), and it was also found that LiCl had a broad spectrum of antiviral effects against multiple influenza virus strains ( P<0.000 1). Conclusions:LiCl may exert antiviral effect by inhibiting the adsorption and entry of H3N2 into A549 cells and the replication of H3N2 in A549 cells, which provides a data reference for the prevention and treatment of viral infection by LiCl.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

Objective To construct models of viral transfection and hypoxia/reoxygenation induced cellular injury in adult mouse cardiomyocytes(AMCMs)isolated using a non-Langendorff method.Methods AMCMs were isolated,extracted,sedimented,and plated using a non-Langendorff method.The morphology and survival rate of the isolated cells were evaluated 2,24,48 and 72 h after plating,and their integrity was observed by immunofluorescence staining for α-actinin.The isolated AMCMs were infected with adenoviruses carrying an RFP-expressing vector and fluorescence images were obtained at 36 and 48 h post-infection and used to calculate transfection efficiency.The cells were cultured under hypoxic conditions for 45 min,reoxygenated for 24 h,and then stained with propidium iodide(PI)to verify establishment of the hypoxia/reoxygenation injury model.Results The survival rates of AMCMs at 2,24 and 48 h after plating were comparable,but survival was significantly reduced at 72 h.The integrity of the AMCMs was good and＞80%of the cells were transfected with adenovirus at 48 h.After hypoxia/reoxygenation treatment,42%of cells were stained by PI,suggesting successful establishment of the AMCM injury model.Conclusions In this study,we developed a non-Langendorff method for the fast and easy isolation of AMCMs with high cell viability.The isolated cells can be efficiently infected with adenovirus and respond to hypoxia/reoxygenation injury.These findings provide a systematic method for isolating AMCMs and for applying gene modification and hypoxia/reoxygenation injury in these cells.

Objective:To investigate the mechanism of benzyl isothiocyanate(BITC) in the treatment of anaplastic thyroid cancer(ATC).Methods:Using network pharmacological analysis, key targets of BITC and ATC were screened, followed by GO and KEGG enrichment analysis. In order to validate the findings, AutoDock software was used to dock BITC and ATC key targets. BITC was applied to two ATC cell lines(8505C and CAL-62). Flow cytometry was used to analyze cell apoptosis. Autophagy inhibitors hydroxychloroquine sulfate(HCQ) and 3-methyladenine(3MA) were used in combination with BITC. Real-time quantitative PCR was conducted to detect the gene level of LC3B, while Western blotting was utilized to examine the expression of NF-κB, LC3B Ⅱ, Beclin-1, and Bcl-2. In animal experiments, a mouse tumor model was constructed using CAL-62 cells, treated with intraperitoneal injections of BITC(100 mg/kg) and normal saline respectively, administered every other day for a total of 21 days. Immunoblotting of tumor tissue was performed to detect the expression of LC3B Ⅱ, Bcl-2, Beclin-1, and NF-κB.Results:A total of 10 key targets with binding energies≤-4.0 kcal/mol were identified. KEGG analysis showed that these genes are mainly involved in NF-κB signaling pathway and apoptosis. BITC inhibited ATC cells with IC50 values of 27.56 μmol/L for 8505C and 28.30 μmol/L for CAL-62. The expression levels of NF-κB, Beclin-1, and Bcl-2 decreased, while LC3B Ⅱ and LC3B gene expression increased. Combining 3MA with BITC enhanced cell inhibition LC3B Ⅱ expression. HCQ increased LC3B Ⅱ expression without enhancing cell and viability inhibition. In the mouse tumor model, compared to the control group, the treatment group had higher LC3B Ⅱ and lower Bcl-2, Beclin-1, and NF-κB levels.Conclusion:BITC could inhibit the growth of ATC cells in vitro and in vivo, disrupt the autophagy degradation, and inhibit the NF-κB pathway.

Objective:To compare thulium laser enucleation of the prostate(ThuLEP)with plasma kinetic resection of the prostate(PKRP)in the treatment of BPH.Methods:We retrospectively analyzed the medical records of 160 cases of BPH treated by ThuLEP(the observation group,n=80)or PKRP(the control group,n=80)in our hospital from January 2021 to December 2023.We recorded the operation time,bladder irrigation time,catheter retention time,hospitalization time,postoperative complica-tions,and pre-and postoperative maximum urinary flow rate(Qmax),residual urine volume(PVR),prostate-specific antigen(PSA)and prostate volume,followed by comparison of the data obtained between the two groups of patients.Results:Compared with the controls,the patients of the observation group showed significantly shorter operation time([67.25±7.24]vs[60.10±5.15]min,P<0.05),bladder irrigation time([46.90±10.77]vs[43.24±6.65]h,P<0.05),catheterization time([5.60±1.31]vs[5.03±1.24]d,P<0.05)and hospitalization time([7.31±2.00]vs[6.55±1.67]d,P<0.05),higher Qmax([18.50±1.24]vs[20.68±1.45]ml/s,P<0.05),lower PVR([12.10±3.53]vs[10.82±3.10]ml,P<0.05),PSA([4.60±0.78]vs[3.38±0.40]μg/L,P<0.05)and prostate volume([25.35±6.46]vs[20.12±5.13]ml,P<0.05)at 3 months after surgery,but no statistically significant difference in the total incidence of postoperative complications(7.50%[6/80]vs 5.00%[4/80],P>0.05).Conclusion:ThuLEP,with its advantages of notable effect,short operation and hospitaliza-tion time,significant improvement of urinary flow dynamics and prostate function,deserves clinical promotion for the treatment of BPH.
