Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

OBJECTIVE To compare the effect on umbilical care of the neonates between the natural dying method and the traditional ethanol disinfection method so as to provide a better method of umbilical nursing for the neo-nates.METHODS A total of 212 healthy neonates who were given birth in the First Medical Center of Chinese PLA General Hospital from Aug.2024 to Nov.2024 were recruited as the research subjects and were randomly divided into the natural drying method with 103 cases and the traditional ethanol disinfection method with 109 cases ac-cording to the method of umbilical care.The time of umbilical cord separation,rate of umbilical bleeding and inci-dence of umbilical secretions were observed and compared between the two groups of neonates.RESULTS There were 16 neonates with the healing time of umbilical cord separation no more than 7 days under the treatment of natural drying method,with 5 cases more than the neonates under the treatment of traditional ethanol disinfection method.The average healing time of umbilical cord separation was 11.69 days under the natural drying method,1.43 days shorter than 13.12 days under the traditional ethanol disinfection method,and there was significant difference(P＜0.05).The rate of umbilical bleeding was 5.82％under the natural drying method,a reduction of 0.60％as compared with 6.42％under the traditional ethanol disinfection method;the incidence of umbilical se-cretions was 0.97％under the national drying method,a reduction of 1.78％as compared with 2.75％under the traditional ethanol disinfection method,but there were no significant differences.CONCLUSIONS As compared with the traditional ethanol disinfection method,the natural drying method can shorten the time of umbilical cord separation,reduce the risk of umbilical infection,and reduce the stress from the neonatal nursing.It is worthy to be promoted.

Objective:To investigate the efficacy of drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE)combined with Apatinib Mesylate and Camrelizumab in the treatment of older patients with hepatocellular carcinoma and portal vein tumor thrombus(PVTT).Methods:A total of 80 older patients with hepatocellular carcinoma and PVTT, admitted to the Second People's Hospital of Pinghu City from January 2020 to December 2023, were selected as the study subjects.Among them, 40 patients receiving DEB-TACE combined with Apatinib Mesylate and Camrelizumab constituted the experimental group, while the other 40 patients receiving Apatinib Mesylate combined with Camrelizumab formed the control group.The response evaluation criteria in solid tumors(RECIST)were employed to assess the clinical efficacy of both groups.Overall survival(OS)and progression-free survival(PFS)were compared, and univariate and multivariate Cox regression analyses were used to analyze the influencing factors of OS in patients.Results:The objective response rate(ORR)and disease control rate(DCR)of the experimental group were significantly higher than those of the control group[60.0%(24/40) vs.32.5%(13/40), 80.0%(32/40) vs.50.0%(20/40), χ2=6.085, 0.013, P=0.013, 0.004]. The median OS and PFS of the experimental group were significantly greater than those of the control group(18.3 months vs.12.2 months, Log-rank χ2=6.470, P=0.011; 8.2 months vs.5.7 months, Log-rank χ2=11.106, P=0.001). Multivariate Cox proportional regression analysis indicated that ALBI grade( HR=1.356, 95% CI: 1.159-1.588, P=0.006), extrhepatic metastasis( HR=1.133, 95% CI: 1.015-1.265, P=0.009), and DEB-TACE( HR=1.921, 95% CI: 1.293-2.854, P=0.001)were independent prognostic factors in older patients with hepatocellular carcinoma and PVTT. Conclusions:The combination of DEB-TACE, Apatinib Mesylate, and Camrelizumab in the treatment of older patients with hepatocellular carcinoma and PVTT can significantly enhance clinical efficacy and extend patient survival.

BACKGROUND:Previous studies found that the proliferative scar-specific long non-coding RNA lncRNA HSFAS is a novel biomarker that can be used in the diagnosis of hypertrophic scar,but how it functions in hypertrophic scar is not clear. OBJECTIVE:To investigate the role and mechanism of lncRNA HSFAS in hypertrophic scar.METHODS:Fresh scar tissue and surrounding normal skin tissue samples from three patients with hypertrophic scar were collected,and tissue immunofluorescence was used to detect the expression of lncRNA HSFAS in frozen sections of two skin tissues. Primary fibroblasts were isolated from proliferative scarred skin tissue and normal skin tissue and cultured by enzyme digestion method. Quantitative real-time PCR was used to detect the mRNA expression of lncRNA HSFAS in cells. The proteins bound to lncRNA HSFAS were detected by RNA pull-down combined mass spectrometry. GO and KEGG were used to analyze the main functions and pathways of lncRNA HSFAS involved in hypertrophic scar progression. The targeted binding of lncRNA HSFAS to proteins was determined by catRAPID and RPISeq website analysis. RESULTS AND CONCLUSION:Compared with normal skin tissue and fibroblasts from normal skin tissue,the expression of lncRNA HSFAS in human hypertrophic scar tissue and primary fibroblasts from hypertrophic scar tissue was significantly increased (P<0.05). There were 510 proteins clearly bound to lncRNA HSFAS by RNA pull-down combined mass spectrometry. The results of GO and KEGG analyses showed that these proteins were mainly involved in RNA splicing and processing,chromosome synthesis and separation,and cell cycle. Among them,the proteins involved in RNA splicing and processing included scaffold attachment factor B2 and DICER1,and the binding fraction with lncRNA HSFAS was higher. The results of bioinformatics analysis showed that lncRNA HSFAS was bound to scaffold attachment factor B2 and DICER1 proteins. To conclude,lncRNA HSFAS may affect gene expression by interacting with scaffold attachment factor B2 and DICER1 proteins to regulate RNA splicing and processing modification,thus promoting the occurrence and development of hypertrophic scar.

Tumor treating fields (TTF) therapy is an innovative tumor treatment modality. Currently, the TTF devices predominantly employ insulated ceramic electrodes as the electric field transmission medium, resulting in low energy transfer efficiency of the electric field and poor portability of the devices. This study proposed an innovative TTF transmission mode and independently designed a conducted-electrode TTF cell culture dish utilizing inert titanium materials. The electric field conduction characteristics were verified through finite element simulations and experimental tests. Finally, based on the self-manufactured conducted-electrode TTF cell culture dish, experiments on the proliferation inhibition of U87 tumor cells by TTF were conducted. The results demonstrated that under an applied TTF voltage of 10 V and frequency of 200 kHz, the electric field intensities within the medium for conducted and insulated electrodes are approximately 2.5 V/cm and 0.7 V/cm, respectively. Compared to conventional insulated TTF systems, the conducted-electrode TTF configuration exhibited a lower electrode voltage drop and a higher electric field intensity in the culture medium, indicating superior electric field transmission efficiency. Following 36 hours of treatment with conducted-electrode TTF on U87 cells, the proliferation inhibition rate reached approximately 50%, demonstrating effective suppression of tumor cell growth. This approach presents a potential direction for optimizing TTF treatment modality and device design.
