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 explore the mechanism of Qiangxin decoction in the treatment of chronic heart failure （CHF） by regulating the inhibitor of nuclear factor-κB alpha/nuclear factor-κB p65 subunit （IκBα/NF-κB p65） signaling pathway-mediated M1 macrophage polarization. METHODS In animal experiments， mice were used as research subjects， and the CHF model was established via coronary artery ligation. Model mice were treated with Qiangxin decoction （21.69 g/kg） for 28 days. After intervention， pathological morphological changes of myocardial tissues and cardiomyocyte apoptosis were observed. Serum levels of inflammatory factors including tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）， myocardial injury marker troponin I3 （TNNI3）， and macrophage-related markers F4/80 and cluster of differentiation 80 （CD80） were detected. In cell experiments， monocyte-macrophage leukemia RAW264.7 cells were induced to undergo M1 polarization by 10 ng/mL lipopolysaccharide combined with 10 ng/mL interferon-γ， followed by 48 h intervention with 10% drug-containing serum of Qiangxin decoction. After intervention， the nuclear translocation of NF-κB p65 and NF-κB p50 was observed. The positive rate of CD80 in cells was measured. The mRNA expression of inflammatory factors including IL-1β， IL-6， IL-8， IL-18， TNF-α， inducible nitric oxide synthase （iNOS）， cyclooxygenase-2 （COX2）， C-C motif chemokine receptor 7 isoform 2 （CCR7-2）， as well as the expression levels of proteins related to the IκBα/NF-κB p65 signaling pathway were detected. RESULTS Animal experimental results showed that Qiangxin decoction alleviated myocardial fibrosis in mice， and significantly reduced the cardiomyocyte apoptosis rate， serum levels of TNF-α and IL-6， as well as the protein expression of TNNI3， F4/80 and CD80 in myocardial tissues （P＜0.05）. Cell experimental results indicated that Qiangxin decoction significantly suppressed the nuclear translocation of NF-κB p65 and NF-κB p50 （P＜0.05）. It significantly decreased the CD80 positive rate， mRNA levels of IL-1β， IL-6， IL-8， IL-18， TNF-α， iNOS， COX2 and CCR7-2， total and nuclear expression of NF-κB p65， total， nuclear and cytoplasmic expression of phosphorylated NF-κB p65， total expression of phosphorylated IκBα （P＜0.05）. Meanwhile， it significantly elevated the total expression of IκBα and cytoplasmic expression of NF-κB p65 （P＜0.05）. CONCLUSIONS Qiangxin decoction can inhibit the activity of the IκBα/NF-κB p65 signaling pathway， reduce the release of pro-inflammatory factors， thereby restraining M1 macrophage polarization， mitigating myocardial fibrosis， and ultimately exerting therapeutic effects against CHF.

OBJECTIVE To explore the expression levels of microribonucleic acid-21(miR-21)and helper T cell(Th)1/Th2 cytokines in peripheral blood of the asthma children complicated with respiratory tract infections of vi-ruses and analyze the significance.METHODS A total of 90 asthma children with respiratory tract infections of vi-ruses(the infection group)and 43 asthma children without respiratory tract infections of viruses(the no infection group)who were treated in the 904th Hospital of the Joint Logistics Support Force of The People's Liberation Ar-my of China were enrolled in the study,and the clinical data were collected from the enrolled patients.The distri-bution of viruses from the children of the infection group was analyzed.The levels of peripheral blood miR-21,Th1 cytokines[interferon-γ(IFN-γ),interleukin(IL)-2]and Th2 cytokines[IL-4,IL-5]were compared between the two groups.The children of the infection group were divided into the mild group,the moderate group and the severe group according to the severity of disease.The levels of the above indexes were compared among the chil-dren with the various degree of illness condition.The association of the illness condition with miR-21,IFN-γ,IL-2,IL-4 and IL-5 was analyzed.RESULTS Respiratory syncytial virus was dominant among the respiratory tract vi-ruses in the infection group,accounting for 32.22％.The levels of IFN-γ and IL-2 of the infection group were low-er than those of the no infection group(P＜0.05),the levels of miR-21,IL-4 and IL-5 of the infection group were higher than those of the no infection group(P＜0.05).The levels of IFN-γ and IL-2 of the severe group were lower than those of the mild group and the moderate group(P＜0.05),while the levels of miR-21,IL-4 and IL-5 of the severe group were higher than those of the mild group and the moderate group(P＜0.05);the levels of IFN-γ and IL-2 of the moderate group were lower than those of the mild group(P＜0.05),and the levels of miR-21,IL-4 andIL-5 of the moderate group were higher than those of the mild group(P＜0.05).Spearman correlation analysis showed that the illness condition of the children was positively correlated with miR-21,IL-4 and IL-5(P＜0.05),which was negatively correlated with IFN-γ and IL-2(P＜0.05).CONCLUSIONS The respiratory tract infections of viruses may aggravate the abnormal rise of peripheral blood miR-21 and the imbalance of Th1/Th2.The above indexes are closely associated with the illness condition of the children.

Objective To enhance the qualified rate of preoperative bladder filling and improve the experience of embryo transfer by implementing a nursing intervention based on the root cause analysis and plan-do-check-act(RCA-PDCA)cycle.Methods A before-after comparative study was conducted among the patients who received embryo transfer at a Tire-ⅢA specialist hospital between January and April 2024.The patient who received embryo transfer between January and February 2024(n=130)were assigned to the control group with routine nursing.Those who received embryo transfer between March and April 2024 were assigned to the trial group(n=136)with nursing intervention based on RCA-PDCA.The two groups were compared in terms of the qualified rate of bladder filling,endometrial visualisation rate,instrument-assisted transfer rate and level of comfort.Results A total of 126 women in the control group and 131 in the trial group completed the study.The patient in the trial group demonstrated significantly higher qualified rate of bladder filling and endometrial visualisation rate in comparison with those in the control group(70.2％vs.38.1％,81.7％vs.51.6％,respectively).The trial group also had lower rates in both of the instrument-assisted transfer and the incidence of mild pain than those in the control group(2.3％vs.7.9％,32.1％vs.53.2％,respectively;P<0.05).Conclusion RCA-PDCA is effective in improving preoperative bladder filling and endometrial visualisation,reducing instrument-assisted transfer and enhancing preoperative bladder comfort in the women receiving embryo transfer.

OBJECTIVE To investigate the effects and potential mechanism of Qiangxin decoction on mitochondrion of rats with chronic heart failure(CHF).METHODS The CHF model was established by ligating the left anterior descending branch of the coronary artery.Modeled rats were divided into model group,Qiangxin decoction low-dose and high-dose groups(12.25,24.50 g/kg,calculated by crude drug),and chemical medicine group(Sacubitril valsartan sodium tablets,10.42 mg/kg),with 10 rats in each group;control group was set up without treatment.Each group of rats was orally administered with the corresponding medication or normal saline twice a day for 28 consecutive days.After the last medication,the contents of N-terminal pro-brain natriuretic peptide(NT-proBNP)and adenosine triphosphate(ATP)in serum and phosphatidic acid(PA)and cardiolipin(CL)in myocardial tissue were all detected;the pathological damage and collagen fibrosis of rat myocardial tissue were observed;the apoptosis of myocardial cells was determined;the ultrastructure of myocardial tissue was observed;the protein expressions of mitofusin 1(Mfn1),Mfn2,optic atrophy protein 1(OPA1)and dynamin-related protein 1(Drp1)were all detected in myocardial tissue.RESULTS Compared with control group,the serum content of NT-proBNP,apoptotic rate of myocardial cells,and relative expressions of S-OPA1 and Drp1 proteins were all increased significantly;serum content of ATP,contents of PA and CL,and relative expressions of Mfn1,Mfn2 and L-OPA1 proteins were all significantly reduced(P＜0.05).There were abnormal membrane tissue structure in various layers of myocardial tissue,degeneration and necrosis of myocardial cells,and severe fibrosis;the mitochondria were swollen,with reduced or absent cristae,and uneven matrix density.After intervention with Qiangxin decoction,the levels of the aforementioned quantitative indicators in serum and myocardial tissue of rats(excluding CL content in the Qiangxin decoction low-dose group)were significantly reversed(P＜0.05);the pathological damage of myocardial tissue had significantly improved,fibrosis had significantly reduced,mitochondrial morphology tended to be normal,cristae had increased,and matrix density was uniform.CONCLUSIONS Qiangxin decoction can regulate myocardial mitochondrial function and structural integrity of CHF rats,thereby improving myocardial energy metabolism and antagonizing myocardial fibrosis,the mechanism of which may be associated with activating PA/Mfn/CL signaling pathway.

Objective To investigate the effectsof adipocyte-specific Structural maintenance of chromosomes 5(Smc5)knockouton glucose and lipid metabolism in mice.Methods Adipocyte-specific Smc5 knockout mice(AKO mice)were constructed based onclustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9(CRISPR/Cas9)systems,and Smc5flox/flox mice(Flox mice)were used as controls.The Smc5 knockout efficiency of adipose tissue in mice was verified by qRT-PCR and Western blot.The body fat content was detected by dual energy X-ray absorptiometry(DEXA).The morphology of adipose tissue was observed by hematoxylin-eosin staining and the area distribution of adipocytes was calculated.TG,HDL-C,LDL-C,free fatty acid(FFA),intraperitoneal glucose tolerance test(IPGTT)and intraperitoneal insulin tolerance test(IPITT)were compared.Results The AKO mouse model of fat specific knockout of Smc5 gene was successfully constructed.Smc5 mRNA in groin fat(iWAT),epididymal fat(eWAT)and brown adipocyte(BAT)of AKO mice,body weight after 15 weeks,organ weight of iWAT at 31 weeks,organ weight of eWAT,organ weight of BAT,body weight,fat mass,fat mass/weight,LDL-C,and percentage of 15-minute blood glucose in IPITT were lower than those of Flox mice(P<0.05 or P<0.01).Conclusions Adipocyte-specific Smc5 gene knockout improves glucose and lipid metabolism by affecting adipose tissue production.

Objective:To investigate the effects of dietary management during labor process on pregnancy outcome of pregnant women with gestational diabetes mellitus.Methods:A retrospective analysis was conducted on the clinical data of 122 pregnant women with gestational diabetes mellitus who delivered at the Wenzhou People's Hospital between January and December 2022. Based on their dietary management methods, these patients were divided into an observation group and a control group, with 61 cases in each group. The control group underwent routine dietary management, whereas the observation group received dietary management during labor process. The labor process indicators and delivery outcomes between the two groups were compared.Results:The energy intake in the observation group was (75.36 ± 9.54) kcal/h, which was significantly higher than (57.23 ± 8.12) kcal/h in the control group ( t = -11.30, P < 0.05). Furthermore, the highest blood glucose levels, hyperglycemia ratios, and proportions of insulin usage in the observation group were (6.74±0.99) mmol/L, 4.92% (3/61), and 3.28% (2/61), respectively, which were significantly lower than those in the control group [(7.72 ± 1.05) mmol/L, 40.98% (25/61), 21.31% (13/61), t = 5.30, χ2 = 22.43, 9.20, all P < 0.05]. Additionally, the observation group had significantly shorter first stage labor time [(418.66 ± 114.26) minutes], active stage time [(281.37 ± 129.65) minutes], and second stage labor time [38.14 ± 17.25) minutes] compared with the control group [(519.93 ± 132.45) minutes, (358.69 ± 153.26) minutes, (51.37 ± 18.62) minutes, t = 4.52, 3.00, 4.07, all P < 0.05]. The incidence of neonatal hypoglycemia in the observation group was 1.64% (1/61), which was significantly lower than 16.39% (10/61) in the control group ( χ2 = 6.39, P < 0.05). Conclusion:Dietary management during the labor process can effectively improve the blood sugar level of pregnant women with gestational diabetes mellitus, as well as enhance the maternal and fetal outcomes.

A 29-year-old man visited Zhongshan Hospital, Fudan University in December 2021. The patient presented with recurrent coughing, sputum, and wheezing, high level of serum total IgE, positive aspergillus fumigatus-specific IgE and extremely severe mixed ventilatory dysfunction. These features and thoracic CT results scan showed bronchiectasis and allergic bronchopulmonary aspergillosis. In consideration of his clinical characteristics, including low levels of fractional exhaled nitric oxide (FeNO), and nasal nitric oxide (nNO), persistent cough after birth, consanguineous marriage of his parents, etc. we ratiocinated a possibility of hereditary diseases, especially primary ciliary dyskinesia (PCD). From this perspective, whole exome sequencing (WES) was performed and the diagnosis of PCD was ultimately confirmed.
