Organoid technology， a rapidly advancing three-dimensional （3D） cell culture platform， can closely mimic the microarchitecture and functions of human digestive organs， effectively overcoming the limitations of conventional two-dimensional cell models and animal experiments. By systematically summarizing the distinctive strengths of organoid technology in simulating digestive physiological and pathological states， constructing digestive system disease models， enabling high-throughput drug screening， and facilitating personalized treatment， this review explored the potential applications of organoids in identifying active components of traditional Chinese medicine （TCM） formulas， evaluating in vitro pharmacokinetics and toxicological parameters， and investigating multi-target synergistic mechanisms. By integrating cutting-edge engineering technologies， organoids are expected to provide a more scientific research platform for TCM， accelerate the modernization of its mechanistic studies， and enhance its scientific value and global impact.

This study investigated the functions and regulatory mechanism of Portulacae Herba and its chemical components on the Toll-like receptor 4(TLR4)/myeloid differentiation primary response 88(MyD88)/nuclear factor kappa B(NF-κB) inflammatory signaling pathway in the colon tissue of mice with dextran sodium sulfate(DSS)-induced ulcerative colitis(UC). A total of 35 mice were randomly divided into groups, including a blank group, a model group, a mesalazine group(0. 5 g·kg~(-1)), and low, medium,and high dose alkaloids from Portulacae Herba groups(9, 18, 36 mg·kg~(-1)), and a combination treatment group, with 5 mice in each group. The blank group was given purified water, while the other groups were continuously given a 3% DSS solution for 7 days to induce the UC model. From day 8 onwards, the treatment group received oral gavage according to the prescribed doses for 14 days. The overall condition, body weight, stool characteristics, and presence of blood in the stool were recorded daily. After the experiment, the disease activity index(DAI) was assessed for each group, and colon length was measured. Histopathological changes in colon tissue were examined using hematoxylin-eosin(HE) staining. The levels of pro-inflammatory cytokines, tumor necrosis factor-α(TNF-α),and interleukin-1β( IL-1β) in serum were measured by enzyme-linked immunosorbent assay( ELISA). The protein and m RNA expression of TLR4, MyD88, and NF-κB in colon tissue were measured using Western blot and quantitative real-time PCR(qPCR).Compared to the blank group, the model group showed a significant decrease in body weight, a notable increase in DAI scores, a significant shortening of colon length, and evident histopathological damage. The levels of inflammatory cytokines TNF-α and IL-1β in the serum were significantly elevated, and the protein and m RNA expression of TLR4, MyD88, and NF-κB in colon tissue were significantly up-regulated. In contrast, the alkaloids from Portulacae Herba treatment groups significantly improved symptoms and reduced body weight loss in mice, decreased DAI scores, alleviated colon shortening, lowered serum levels of TNF-α and IL-1β,significantly down-regulated the expression levels of TLR4, MyD88, and NF-κB proteins and genes in colon tissue, as well as reduced histopathological damage. Therefore, the study suggests that alkaloids from Portulacae Herba can alleviate intestinal inflammation damage in DSS-induced UC mice, with its mechanism involving the TLR4/MyD88/NF-κB signaling pathway.

Objective To analyze the TCM syndrome and treatment rule for the treatment of chronic atrophic gastritis based on data mining;To provide reference for its clinical treatment.Methods With the help of the big data platform of evidence-based literature of TCM covering several dominant diseases in the field of digestion,literature on the experience of famous doctors,theoretical discussion and case reports in the treatment of chronic atrophic gastritis published from 1 January 2000 to 31 July 2022 was retrieved.Medical records were screened according to the inclusion and exclusion criteria.The data of TCM disease names,clinical symptoms,tongue manifestation,pulse manifestation,TCM syndrome,TCM treatment method and other terms in medical records were standardized and statistically analyzed.Results Totally 169 articles were included,including 228 medical cases,involving 228 patients,with a cumulative number of 361 visits,with an average age of(53.17±11.11)years old,with the largest number of 50-60 years old.Chronic atrophic gastritis mostly belonged to the categories of"stomach pain"and"epigastric puffiness"in TCM,and its main symptoms were stomach pain,epigastric puffiness and belching.The common tongue manifestation include dark red tongue,white moss,thin or greasy moss.The common pulse manifestation included wiry slippery pulse,wiry thready pulse and wiry pulse.The high-frequency syndromes included liver-stomach qi stagnation syndrome,spleen-stomach dampness-heat syndrome,liver-qi stagnation and spleen-qi deficiency syndrome.The disease locations were mainly in the stomach,spleen and liver,and the syndrome elements were mainly qi deficiency,qi stagnation,blood stasis,dampness and heat,etc.The complex syndrome elements were more than the single syndrome elements,and the two syndrome elements of qi deficiency + qi stagnation was the most common.The most commonly used treatment methods were supplementing,regulating qi and regulating blood.Conclusion The treatment of chronic atrophic gastritis with TCM mostly focuses on the stomach,spleen and liver.The core syndrome elements are qi deficiency,qi stagnation,and blood stasis.The methods of nourishing qi and strengthening the spleen,soothing the liver and stomach,regulating qi and blood are often used.

Spleen deficiency is an important part of the theoretical system of Traditional Chinese Medicine,which has experienced the process of origin,standardization,maturity,perfection and development in different historical periods.The physiological function of the spleen in Traditional Chinese Medicine involves"the spleen governs transportation and transformation,promotes blood circulation";The study of"spleen governing transportation and transformation"divided into"spleen governing transportation"and"spleen governing transformation"from the function of spleen,which is more conducive to explaining the scientific connotation of spleen governing transportation and transformation.Spleen governing transport and transformation is the basis of spleen governing clearing,and spleen governing clearing is the purpose of spleen governing transport and transformation.Spleen governing blood circulation is the outcome of spleen governing clearing,and there is a progressive logical hierarchy relationship between them.With the rise of proteomics,metabonomics and intestinal flora research,it provides technical support for the study of spleen deficiency syndrome;In addition,based on the correlation between spleen of Traditional Chinese Medicine and the functions of endoplasmic reticulum,the material basis of essence of spleen deficiency is discussed from the perspective of endoplasmic reticulum stress,which provides a new direction for the study of spleen deficiency.

The overlapping symptoms of functional gastrointestinal disorders(FGIDs)are complicated,which makes the diagnosis and treatment of FGIDs more difficult,at the same time aggravates the patients'psychological and economic burden and results in the consumption of medical resources.Functional dyspepsia(FD)and gastroesophageal reflux disease(GERD)may have a potential Pathophysiology relationship,which is mainly related to gastrointestinal motility disorders caused by lower esophageal sphincter relaxation and delayed gastric emptying.The spleen is the foundation of nurture,the source of Qi and blood biochemistry,disperses the fine in the whole body,contains the energy and the material which the organism needs.Mitochondria are known as"Power factories",producing heme as well as ATP from tricarboxylic acid cycle and oxidative phosphorylation to fuel life.The functions of spleen and mitochondria embody the same life activity in two different ways.It has been found that the dysfunction of interstitial cells of cajal(ICC)caused by energy metabolism disorder of mitochondria is closely related to gastrointestinal motility disorder.Therefore,based on the"Correlation between spleen and mitochondria",this paper discusses the relationship between ICC dysfunction and overlapping FD and GERD.It is suggested that the dysfunction of ICC caused by spleen deficiency and mitochondrial energy metabolism disorder is the important pathogenesis of overlapping FD and GERD.In addition,starting from the theory of Tong Jiang,it can provide higher clinical practical value for the diagnosis and treatment of overlapping FD and GERD.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

OBJECTIVE To study the immunomodulatory effect of Guipi pills on D-galactose（D-gal）-induced aging mice. METHODS The immune-related targets and related pathways for Guipi pills to exert immune effects were screened by network pharmacology and verified through pharmacodynamic experiments. Totally 105 male ICR mice were randomly divided into blank control （CON） group， model control （MOD） group， positive control （POS） group， Guipi pills low-dose （GD） group and Guipi pills high-dose （GG） group. Except for the CON group， other groups were subcutaneously injected with 400 mg/kg D-gal to induce the aging model； CON group and MOD group were given distilled water， POS group was given 300 mg/kg pidotimod oral solution intragastrically， GD group and GG group were given Guipi pills 300， 600 mg/kg intragastrically， once a day， for 8 weeks. After medication， the serum and spleen were collected， and the contents of interleukin 2 （IL-2）， IL-4， IL-6 and tumor necrosis factor α （TNF-α）， and the contents of immunoglobulin G （IgG）， IgM and IgA were detected. The spleen index was calculated and the histopathological changes in the spleen were observed. The activities of superoxide dismutase （SOD）， glutathione peroxidase （GSH- Px） and malondialdehyde （MDA）， and the content of 8-hydroxy-2 deoxyguanosine （8-OHdG） in spleen were detected； the expression of TNF/phosphoinositide-3-kinase-threonine protein kinase （PI3k-Akt）-related proteins in spleen was detected except for POS group. RESULTS The results of network pharmacology showed that TNF， IL-6 and Akt1 were core targets. The results of pharmacodynamic study showed that compared with MOD group， the contents of IL-2， IL-4， IgG， IgM and IgA were increased significantly in Guipi pills groups， while the contents of TNF-α and IL-6 were decreased significantly； the spleen index was increased significantly （P＜0.05 or P＜0.01）. The phenomenon of diffuse proliferation of lymphocytes was improved， the spleen cells were closely arranged， and the line between the white pulp and red pulp was clear. The activities of SOD and GSH-Px in spleen were increased significantly， while the activity of MDA， the content of 8-OHdG， and the protein expressions of TNF-α， PI3K and p-Akt were decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Guipi pills can regulate the immune function of D-gal-induced aging mice， which is related to regulating the TNF/PI3k-Akt pathway， thereby reducing oxidative stress damage in spleen tissue of mice， and regulating protein expressions of TNF-α， PI3K and p-Akt.

Objective: To evaluate the impact of bleomycin/etoposide/cisplatin (BEP) and paclitaxel/carboplatin (PC) chemotherapy regimens on the fertility and prognostic outcomes in malignant ovarian germ cell tumor (MOGCT) patients who underwent fertility-sparing surgery (FSS). Methods: A propensity score matching algorithm was performed between the BEP and PC groups. The χ2 test and the Kaplan-Meier method were used to compare the fertility outcome, disease-free survival (DFS) and overall survival (OS). The Cox proportional hazards regression analysis was used to identify risk factor of DFS. Results: We included 213 patients, 185 (86.9%) underwent BEP chemotherapy, and 28 (13.1%) underwent PC chemotherapy. The median age was 22 years (range, 8–44 years), and the median follow-up period was 63 months (range, 2–191 months). Fifty-one (29.3%) patients had a pregnancy plan, and 35 (85.4%) delivered successfully. In the before and after propensity score matching cohorts, there were no significant differences in spontaneous abortion, selective termination of pregnancy, during-pregnancy status, and live birth between the BEP and PC groups (p>0.05). Fourteen (6.6%) patients experienced recurrence, including 11 (5.9%) in the BEP group and 3 (10.7%) in the PC group. Four (1.9%) patients in the BEP group died. Kaplan-Meier analysis revealed no significant differences in DFS (p=0.328) and OS (p=0.446) between the BEP and PC groups, and the same survival results were observed in the after matching cohort. Conclusion The PC regimen is as safe as the BEP regimen for MOGCT patients with fertility preservation treatment, and no differences were observed in fertility and clinical prognosis.
