Diarrhea-irritable bowel syndrome (IBS-D) is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated, effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine (TCM) and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D, we discovered that rats were the preferred animals for modeling, and the models were mainly induced by single factors, double factors, or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition, the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency, and few models were established for the syndromes of spleen-kidney Yang deficiency, spleen-stomach dampness-heat, spleen deficiency and dampness excess, and cold and heat in complexity. Therefore, it is essential to improve the existing or develop new animal models of IBS-D in the future, so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Syndrome of dampness-heat of spleen and stomach is one of the complex syndromes of the spleen and stomach,which is difficult to differentiate and treat in TCM.According to the theoretical connotation of"attacking it according to its combination",it is suggested that the syndrome of dampness-heat of spleen and stomach should be comprehensively differentiated and treated from five aspects,including"attacking the visible pathogens combined with the invisible ones"(removing dampness and warming yang),"treating the fu-organs sharing interior-exterior relationship with zang-organs"(clearing away damp-heat pathogens of stomach with drugs of bitter taste and cold property),"formulating the treatment according to the likes and dislikes of the five internal organs"(developing a life adjustment plan favored by the spleen and stomach),"administrating drug according to the five organs"(medications according to the spleen and stomach),"weighing the severity and applying the treatment"(pay attention to the details,and treating according to syndrome differentiation).A clinical case is exampled,with the purpose to provide reference for the prevention and treatment of syndrome of dampness-heat of spleen and stomach.

OBJECTIVE:
To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD).
METHODS:
We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count.
RESULTS:
The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD.
CONCLUSION
Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Objective:
To study the effects of Porphyromonas gingivalis (P. g) infection with I, II and IV fimA genotypes on the expression of IL-1beta, IL-6 and TNF-alpha in human umbilical vein endothelial cells (HUVECs).
Methods :
HUVECs infected with different fimA genotypes were divided into the fimA type I stimulation group, fimA type II stimulation group, fimA type IV stimulation group. In addition, a positive control group (E. coli LPS stimulation) and negative control group (cell culture medium only) were included. Cell proliferation was detected by MTT assay, and cell apoptosis was detected by flow cytometry. IL-1β, IL-6, TNF-α levels in the supernatant of HUVECs after P. g stimulation were assessed by ELISA at 2 h, 6 h and 24 h.
Results :
HUVECs were infected by P. g with fimA type I,fimA type II and LPS for 24 h. Cell proliferation was inhibited compared with the negative control group (P < 0.05), but there was no significant difference in the apoptosis rate between P. g infection and the negative control group. IL-1β levels in cell culture supernatants were higher at 2th than 6 and 24 h after stimulation of HUVECs with different fimA genotypes, while the IL-6 levels were higher at 24 h than the other time, while the TNF-α levels were no significant difference at every time. After fimA type II and IV P. g infection, IL-1β, IL-6, and TNF-α levels were increased compared with fimA type I P. g (P < 0.05).
Conclusion
Different P. g fimA genotypes have different effects on stimulating HUVECs to induce dysfunction. Here, fimA type II and IV P. g exhibit a strong ability to upregulate the secretion of IL-1β, IL-6 and TNF-alpha.

Stroke has become the leading cause of death in Chinese residents. As the cornerstone of the primary and secondary prevention of ischemic stroke, aspirin can prevent the occurrence and recurrence of ischemic stroke in a certain extent. However, some patients stil have vascular events after taking aspirin regularly or higher platelet aggregation rate. This phenomenon is caled aspirin resistance or aspirin low reactivity. This article reviews the occurrence, detection methods, and treatment measures of aspirin resistance in patients with ischemic stroke.

Objective No consensus has yet been achieved on the relationship of serum albumin with the functional out-come of acute ischemic stroke.The aim of our study was to determine whether the serum albumin level was associated with the short-term functional outcome of acute ischemic stroke in well-nourished patients. Methods Totally, 113 patients with first-ever acute ischemic stroke were recruited from Nanjing Stroke Registration Program between January and June 2015.Baseline data including de-mographic and body parameters, vascular risk factors, and laboratory results were collected.The NIH Stroke Scale ( NIHSS) was used to evaluate the severity of neurological deficits and the modified Rankin Scale ( mRS ) employed to assess the short-term functional outcome.According to the mRS at discharge, the patients were divided into a good outcome group ( mRS<3 ) and a poor out-come group ( mRS≥3 ) .The independent predictors of the short-term functional outcome were evaluated by multivariate logistic regression analysis. Results Of the 113 acute ischemic stroke patients included, 52 (46.0%) were in the good outcome group, and 61 (54.0%) in the poor outcome group.Those in the former group had a significantly higher BMI, lower serum LDL-C, lower WBC count, and lower NIHSS at admission than those in the latter .Multivariate logistic regression analysis showed that low serum albumin, NIHSS at admission, and arteriole occlusion were independent predictors of the poor short-term functional outcome ( OR=0.684, 95% CI:0.490-0.956, P=0.026). Conclusion Low serum albumin is an independent predictor of poor short-term functional outcome in acute ischemic stroke patients in well-nourished status.

AIM:To evaluate the ability of dendritic cells (DCs) loaded with tumor lysate to initiate cell mediated immune responses by stimulating naive T cells, and the efficiency of activated T cells to kill autologous tumor cells in vitro. METHODS: The peripheral blood lymphocytes and monocytes were obtained from the advanced renal cell carcinoma patient by eonglutination method. The immature dendritic cells were generated in the presence of interleukin -4(IL-4) and granulocyte/macrophage colony-stimulating factor (GM-CSF) from monocytes of healthy individuals.These cells were pulsed with tumor lysate or not. Induction of tumor-specific cytotoxic T lymphocytes(CTLs) response by mature dendritic cells (mDCs) was evaluated by the CD95(Fas) expression assay through FCM and the cytotoxic assay a gninst autolognns human tumor cells. RESULTS: Human immature dendritic cells and T cells obtained from healthy donors were stimulated with tumor- pulsed dendritic cells. The immature dendritic cells were applied to the cytotoxicity assay a gainst target autologons tumor cells. The CD95 (Fas) expression, IFN-γ, and TNF -α secreted by the CTLs in tumor lysate-plused DC group were higher than those of other groups. The capacity of the CTLs to kill autolognns tumor cells was significantly different(P<0. 05). Antigen-specific DCs vaccine can induce T cells activation and proliferation, thus we can obtain higher proportion of tumor specific cytotoxic T cells(CTLs), and enhance the CTLs to secret IFN-γ and TNF-α. CONCLUSION: Our results indicate that monocyte-derived human dendritic cells pulsed with tumor lysate could in duce the specific antitumor effect against autologons tumors. This in vitro model offers a new and simple approach to the development of DC + CTL - based immunotherapy.
