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 differences in clinical characteristics between persistent atrial fibrillation(PsAF)combined with heart failure with preserved ejection fraction(HFpEF)and heart failure with reduced ejection fraction(HFrEF),and to clarify the influencing factors and predictive efficacy of PsAF combined with heart failure(HF).Methods A total of 117 inpatients with PsAF admitted to Laiyang Hospital of Traditional Chinese Medicine from February 2023 to February 2025 were selected and divided into PsAF+HFpEF group(n=42),PsAF+HFrEF group(n=34),and PsAF group(n=41)according to the type of HF.The baseline data,serum uric acid(UA)levels and echocardiographic parameters[left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),left atrium diameter(LAD),right ventricular diameter(RVD),left ventricular end diastolic volume(LVEDV),left ventricular end systolic volume(LVESV),stroke volume(SV)and pulmonary artery systolic pressure(PASP)]of three groups of patients were compared.Multivariate Logistic regression analysis was used to identify the independent influencing factors of PsAF combined with HF,and the receiver operating characteristic(ROC)curve was drawn to evaluate the predictive efficacy.Results The proportions of New York Heart Association(NYHA)cardiac function grade Ⅲ-Ⅳ and hyperuricemia,and heart rate,N-terminal pro-brain natriuretic peptide(NT-proBNP),UA in patients of PsAF+HFpEF group and PsAF+HFrEF group were significantly higher than those in PsAF group(P＜0.05).The serum creatinine level of patients in PsAF+HFrEF group was significantly higher than that in PsAF+HFpEF group and PsAF group(P＜0.05).The levels of LVESD,LVEDD,LAD,RVD,PASP,LVEDV and LVESV in PsAF+HFrEF group were significantly higher than those in PsAF group(P＜0.05).The LVESD,LVEDD,LAD,LVEDV and LVESV of patients in PsAF+HFpEF group were significantly lower than those in PsAF+HFrEF group(P＜0.05),LAD and PASP were significantly higher than those in PsAF group(P＜0.05).There was a statistically significant difference in LVEF among three groups of patients(P＜0.05),in sequence:PsAF group＞PsAF+HFpEF group＞PsAF+HFrEF group.Multivariate Logistic regression analysis showed that NT-proBNP,UA,and NYHA cardiac function grade Ⅲ-Ⅳ were all independent risk factors for PsAF complicated with HF,and LVEF was an independent protective factor(P＜0.05).The area under the curve for combined prediction of PsAF combined with HF by NT-proBNP+UA+LVEF was 0.967.Conclusion NT-proBNP,UA and LVEF are all independent predictors of PsAF complicated with HF.The combination of three has highly efficient predictive value and provides an efficient tool for clinical risk stratification.

Objective:To explore the sequential chemotherapy efficacy of different chemotherapeutic regimens in ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma.Methods:A retrospective analysis was conducted on clinical and pathological data of 100 patients with platinum-sensitive ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma treated at Peking University Peopel′s Hospital from January 1992 to January 2019. All patients underwent staging surgery or cytoreductive surgery followed by adjuvant chemotherapy. Based on different postoperative adjuvant chemotherapy regimens, patients were divided into the sequential chemotherapy group (70 cases) and the conventional chemotherapy group (30 cases). Clinical and pathological characteristics, chemotherapy efficacy, adverse reactions, and prognosis were compared between the two groups.Results:(1) Clinical and pathological characteristics: the age, tumor types (including ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma), pathological types, International Federation of Gynecology and Obstetrics (FIGO) stage, postoperative residual disease size, presence of neoadjuvant chemotherapy, and total number of chemotherapy cycles were compared between the sequential chemotherapy group and the conventional chemotherapy group. There were no statistically significant differences observed in these characteristics between the two groups (all P>0.05). (2) Chemotherapy efficacy: the median sum of complete response (CR)+partial response (PR) duration in the sequential chemotherapy group was 80.0 months (range: 39 to 369 months), whereas in the conventional chemotherapy group, it was 28.0 months (range: 13 to 52 months). A statistically significant difference was observed between the two groups ( Z=-7.82, P<0.001). (3) Chemotherapy adverse reactions: in the sequential chemotherapy group, 55 cases (79%, 55/70) experienced bone marrow suppression and 20 cases (29%, 20/70) had neurological symptoms. In the conventional chemotherapy group, these adverse reactions occurred in 11 cases (37%, 11/30) and 2 cases (7%, 2/30), respectively. Statistically significant differences were observed between the two groups for both bone marrow suppression and neurological symptoms (all P<0.05). For the other chemotherapy adverse reactions compared between the two groups, no statistically significant differences were observed (all P>0.05). (4) Prognosis: during the follow-up period, the recurrence rate in the sequential chemotherapy group was 73% (51/70) and in the conventional chemotherapy group was 100% (30/30). The median sum of recurrence-free interval was 70.5 months (range: 19 to 330 months) in the sequential chemotherapy group and 15.0 months (range: 6 to 40 months) in the conventional chemotherapy group. Statistically significant differences were observed between the two groups for both recurrence rate and median recurrence-free interval (all P<0.01).In the sequential chemotherapy group, the median progression-free survival (PFS) time was 84.0 months (range: 34 to 373 months), and the median overall survival (OS) time was 87.0 months (range: 45 to 377 months). In contrast, in the conventional chemotherapy group, the median PFS time was 30.5 months (range: 14 to 60 months), and the median OS time was 37.5 months (range: 18 to 67 months). Statistically significant differences were observed between the two groups for both PFS and OS (all P<0.001). In the sequential chemotherapy group, the 3-year, 5-year, and 10-year OS rates were 100% (70/70), 93% (65/70), and 21% (15/70), respectively. In contrast, in the conventional chemotherapy group, the OS rates were 50% (15/30) at 3 years, 3% (1/30) at 5 years, and 0 at 10 years, respectively. The two groups were compared respectively, and the differences were statistically significant (all P<0.05). Conclusions:Sequential chemotherapy significantly prolongs PFS and OS in patients with ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma. The efficacy is superior to that of the conventional chemotherapy, with manageable adverse reactions. The use of sequential chemotherapy as first-line treatment for patients with ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma is recommended.

Objective To investigate the expression of ALKBH3-AS1 in peripheral blood CD4+T cells of patients with systemic lupus erythematosus(SLE)and its correlation with T helper cell 17/regulatory T cells(Th17/Treg)and disease activity.Methods A total of 60 patients diagnosed with SLE in Leshan Hospital of Traditional Chinese Medicine from July 2020 to March 2024 were retrospectively collected.According to SLEDAI score,they were divided into active group(n=33,SLEDAI ≥ 10 score)and stable group(n=27,SLEDAI＜10 score).At the same time,52 healthy subjects were selected as control group.The general data of three groups were collected and peripheral blood mononuclear cell(PBMC)was obtained by centrifugation in peripheral blood.CD4+T cells were isolated by immunomagnetic beads,and Th17/Treg ratio was detected by flow cytometry.The relative expression levels of ALKBH3-AS1 and retinoid-related orphan receptor γ t(ROR γ t)in CD4+T cells were detected by fluorescence quantitative PCR.The contents of transforming growth factor(TGF)-β and interleukin(IL)-17 in serum were determined by enzyme-linked immunosorbent assay(ELISA).The levels of C3 and C4 were determined by rate scattering immunoturbidimetry.Pearson analyzed the correlation between ALKBH3-AS1,Th17 and various clinical indicators in SLE patients.Logistic regression analysis of the influencing factors in patients with severe SLE showed that the difference was statistically significant.Results Hb,ALB,ALKBH3-AS1 mRNA,CD4+T,complement C3 and C4 in the control group were significantly higher than those in SLE group(t/Z=3.245,-11.169,-12.675,-17.829,-15.240,-19.212),RDW,TGF-β,RORγ t,Th17/Treg,IL-17,and CRP in the control group were lower than that in SLE group(t/Z=4.206,10.054,19.869,37.942,50.463,3.115),and the differences were statistically significant(all P＜0.05).ALB,ALKBH3-AS1 mRNA,CD4+T in the active group were significantly lower than those in the stable group(t/Z=-8.918,-2.483,-11.694),CRP,TGF-β,RORγt,Th17/Treg,and IL-17 were significantly higher than those in the stable group(t/Z=3.121,5.671,1.787,14.720,12.044),and the differences were statistically significant(all P＜0.05).Pearson analysis showed that ALKBH3-AS1 was positively correlated with CD4+T(r=0.663),and negatively correlated with Th17/Treg,IL-17,TGF-β,ROR γ t,SLED AIindex(r=-0.687,-0.715,-0.705,-0.678,-0.671),Th17/Treg was negatively correlated with CD4+T(r=-0.817),and positively correlated with IL-17,TGF-β,ROR γ t,SLED AI index with statistical significance(r=0.687,0.767,0.598,0.704).Logistics regression analysis,showed that increased CD4+T[OR(95％CI):0.715(0.304～0.904)]proportion and up-regulated ALKBH3-AS1[OR(95％CI):0.654(0.320～0.987)]expression were protective factors affecting disease activity in SLE patients.The contents of TGF-β[OR(95％CI):1.487(1.120～1.814)]and IL-17[OR(95％CI):1.294(1.217～1.887)]were up-regulated,the proportion of Th17/Treg[OR(95％)CI:1.674(1.361～1.679)]was up-regulated,and the relative expression of ROR γ t[OR(95％)CI:1.547(1.252～1.941)]was increased as risk factors affecting disease activity in SLE patients.Conclusion The down-regulated expression of ALKBH3-AS1 and up-regulated expression of TGF-β,ROR γ t and IL-17 in CD4+T cells of SLE patients are all correlated with disease activity,and can be potential biomarkers for diagnosis,disease activity and efficacy evaluation in SLE patients.

ObjectiveTo investigate the possible mechanism of modified Gegen Qinlian Decoction （葛根芩连汤） in treatment of ulcerative colitis （UC） from the view of intestinal mucosal epithelial barrier damage and epithelial mesenchymal transition. MethodsSixty male C57BL/6J mice were divided into blank group， model group， western medicine control group， and low-， medium-， and high-dose modified Gegen Qinlian Decoction groups， with 10 mice in each group. Except for the blank group， 3% dextran sodium sulfate （DSS） was used to induce colitis model by free drinking for 7 days， and on the first day of modelling， 6， 12， and 24 g/（kg·d） of modified Gegen Qinlian Decoction were given to the low-， medium-， and high-dose groups respectively， 5-aminosalicylic acid （5-ASA） 100 mg/（kg·d） given by gavage to western medicine control group， and 10 ml/kg distilled water were given to blank and model group by gavage， once a day for 7 days. Body mass of mice was recorded and disease activity index （DAI） scores were performed daily. The mice were anesthetized after 24h of the last administration and the colon was taken to observe the length of colon， HE staining was applied to observe the damage of colonic mucosa and score pathological states， Masson staining to detect the deposition of colonic collagen fibers， immunofluorescence to observe the distribution of F-actin in colonic mucosal epithelium， and immunohistochemistry to detect the expression of tight junction protein ZO-1， Occludin， E-cadherin and Vimentin.

Objective:To summarize the situation of dead newborns and their parents after parents gave up treatment, and analyze the reasons and emotional needs of parents who gave up treatment, so as to provide reference for reducing neonatal mortality and negative emotions of parents.Methods:A retrospective study was conducted to collect the data of neonates and mothers who died after giving up treatment reported in Hunan Children′s Hospital from January 2019 to December 2021. The general information, perinatal risk factors, and the incidence of in-hospital diseases were analyzed. Then, semi-structured interviews were conducted with parents of newborns who died after giving up treatment from February to December 2021. Understand why parents give up treatment and their emotional needs.Results:A total of 172 newborns died after giving up were included in the analysis, including 103 males (59.88%) and 74 premature infants (43.02%); Umbilical cord, placenta and amniotic fluid abnormalities were 21 cases (12.21%), 39 cases (22.67%) and 25 cases (14.53%), respectively. Birth asphyxia was 31 cases (18.02%), including severe asphyxia in 18 cases (10.46%); There were 21 (12.21%), 35 (20.35%) and 30 (17.44%) cases of maternal infection in the third trimester, hypertension in pregnancy and diabetes in pregnancy, respectively. The top three causes of death were septicemia (18.02%), congenital malformation (16.86%) and severe pneumonia (10.47%). The main reason why parents give up treatment was that the child′s disease was critical and irreversible, and parents had strong emotional needs for hospice care in their hearts.Conclusions:There are many high risk factors of perinatal death of newborns after giving up treatment. Sepsis is the primary cause of death, and strengthening perinatal health care is fundamental. Parents have a strong demand for hospice care, so it is of practical significance to implement family-centered hospice care model for such special newborns.
