BACKGROUND: Endoscopic sphincterotomy (EST) is widely used to treat common bile duct stones (CBDS); however, long-term studies have revealed the increasing incidence of recurrent CBDS after EST. Loss of sphincter of Oddi function after EST was the main cause of recurrent CBDS. Reparation of the sphincter of Oddi is therefore crucial. This study aims to investigate the effectiveness and safety of endoclip papilloplasty (ECPP) for repairing the sphincter of Oddi and elucidate its mechanism. METHODS: Eight healthy Bama minipigs were randomly divided into the EST group and the ECPP group at a 1:1 ratio, and bile samples were collected before endoscopy and 6 months later. All minipigs underwent transabdominal biliary ultrasonography for the diagnosis of cholelithiasis 6 months after endoscopy. The biliary microbiota composition and alpha and beta diversity were analyzed by 16S ribosomal RNA gene sequencing. Differential metabolites were analyzed by bile acid metabolomics to explore the predictive indicators of cholelithiasis. RESULTS: Three minipigs were diagnosed with cholelithiasis in the EST group, while none in the ECPP group showed cholelithiasis. The biliary Firmicutes/Bacteroidota (F/B) ratio was increased after EST and decreased after ECPP. The Chao1 and observed species index significantly decreased 6 months after EST ( P  = 0.017 and 0.018, respectively); however, the biliary α-diversity was similar before and 6 months after ECPP. The β-diversity significantly differed in the EST group before and 6 months after EST, as well as in the ECPP group before and 6 months after ECPP (analysis of similarities [ANOSIM]: R  = 0.917, P  = 0.040; R  = 0.740, P  = 0.035; respectively). Glycolithocholic acid (GLCA) and taurolithocholic acid (TLCA) accumulated in bile 6 months after EST. CONCLUSIONS ECPP has less impact on the biliary microenvironment than EST and prevents duodenobiliary reflux by repairing the sphincter of Oddi. The bile levels of GLCA and TLCA may be used to predict the risk of cholelithiasis.

Intestinal fibrosis is a major complication of inflammatory bowel disease (IBD), leading to a high incidence of surgical interventions and significant disability. Despite its clinical relevance, no targeted pharmacological therapies are currently available. This review aims to explore the underlying mechanisms driving intestinal fibrosis and address unresolved scientific questions, offering insights into potential future therapeutic strategies. We conducted a literature review using data from PubMed up to October 2024, focusing on studies related to IBD and fibrosis. Intestinal fibrosis results from a complex network involving stromal cells, immune cells, epithelial cells, and the gut microbiota. Chronic inflammation, driven by factors such as dysbiosis, epithelial injury, and immune activation, leads to the production of cytokines like interleukin (IL)-1β, IL-17, and transforming growth factor (TGF)-β. These mediators activate various stromal cell populations, including fibroblasts, pericytes, and smooth muscle cells. The activated stromal cells secrete excessive extracellular matrix components, thereby promoting fibrosis. Additionally, stromal cells influence the immune microenvironment through cytokine production. Future research would focus on elucidating the temporal and spatial relationships between immune cell-driven inflammation and stromal cell-mediated fibrosis. Additionally, investigations are needed to clarify the differentiation origins of excessive extracellular matrix-producing cells, particularly fibroblast activation protein (FAP) + fibroblasts, in the context of intestinal fibrosis. In conclusion, aberrant stromal cell activation, triggered by upstream immune signals, is a key mechanism underlying intestinal fibrosis. Further investigations into immune-stromal cell interactions and stromal cell activation are essential for the development of therapeutic strategies to prevent, alleviate, and potentially reverse fibrosis.

The small intestine is essential for digestion, nutrient absorption, immune regulation, and microbial balance. Its epithelial lining, containing specialized cells like Paneth cells and tuft cells, is crucial for maintaining intestinal homeostasis. Paneth cells produce antimicrobial peptides and growth factors that support microbial regulation and intestinal stem cells, while tuft cells act as chemosensors, detecting environmental changes and modulating immune responses. Along with immune cells such as intraepithelial lymphocytes, innate lymphoid cells, T cells, and macrophages, they form a strong defense system that protects the epithelial barrier. Disruptions in this balance contribute to chronic inflammation, microbial dysbiosis, and compromised barrier function-key features of inflammatory bowel disease, celiac disease, and metabolic syndromes. Furthermore, dysfunctions in the small intestine and immune cells are linked to systemic diseases like obesity, diabetes, and autoimmune disorders. Recent research highlights promising therapeutic strategies, including modulation of epithelial and immune cell functions, probiotics, and gene editing to restore gut health and address systemic effects. This review emphasizes the pivotal roles of small intestinal epithelia and immune cells in maintaining intestinal homeostasis, their involvement in disease development, and emerging treatments for intestinal and systemic disorders.

Juvenile idiopathic arthritis (JIA) is the most common condition of chronic rheumatic disease in children. JIA is an autoimmune or autoinflammatory disease, with unclear mechanism and limited treatment efficacy. Recent studies have found a number of alterations in gut microbiota and its metabolites in children with JIA, which are related to the development and progression of JIA. This review focuses on the influence of the gut microbiota and its metabolites on immune function and the intestinal mucosal barrier and discuss the key role of the gut-joint axis in the pathogenesis of JIA and emerging treatment methods based on gut microbiota and its metabolites. This review could help elucidate the pathogenesis of JIA and identify the potential therapeutic targets for the prevention and treatment of JIA.

Amyand’s hernia is a hernia where the appendix is within the inguinal hernial sac. It is often diagnosed by chance due its indeterminate clinical presentation. This case reports a 50-year-old Filipino male who presented with direct and rebound tenderness on the lower abdomen in the presence of a right inguinal bulge. CT scan showed an appendix coursing inferiorly into the pelvis, herniating through a 2 cm defect of the anterior abdominal muscle into the right inguinal region along with mesenteric fat. Laparoscopy confirmed acute appendicitis within an inguinal hernia (Amyand’s hernia Type 2). Diagnostic laparoscopy, appendectomy and primary repair of the right inguinal ring were performed. The patient had an unremarkable post-operative course and was discharged after 2 days. He was advised to undergo IPOM to prevent hernia recurrence. Laparoscopic management can be a safe option for cases of Amyand’s hernia.

OBJECTIVE: To observe the clinical efficacy of thread-embedding at the combined lower he-sea and front-mu points for functional constipation with intestinal excess heat. METHODS: A total of 80 patients with functional constipation of intestinal excess heat were randomly divided into a thread-embedding group (40 cases, 2 cases dropped out) and a Chinese patent medication group (40 cases, 1 case dropped out). Based on the theory of combined lower he-sea and front-mu points for diseases of fu organs, Zhongwan (CV12), Guanyuan (CV4) and bilateral Zusanli (ST36), Shangjuxu (ST37), Tianshu (ST25), Xiajuxu (ST39) were selected and thread-embedding therapy was delivered in the thread-embedding group, once a week. Maren Runchang pill was given orally in the Chinese patent medication group, 6-12 g each time, twice a day. Both groups were treated for 4 weeks. Before and after treatment, the scores of constipation assessment scale (CAS), Bristol stool form scale (BSFS), patient-assessment of constipation quality of life (PAC-QOL) and TCM syndrome were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the CAS scores and the TCM syndrome scores were decreased compared with those before treatment (P<0.05), while the BSFS scores were increased compared with those before treatment (P<0.05) in the two groups; the total scores, as well as the physical discomfort and psychosocial discomfort scores of PAC-QOL were decreased compared with those before treatment (P<0.05) in the two groups, the worry and anxiety, and the satisfaction scores of PAC-QOL were decreased compared with those before treatment (P<0.05) in the thread-embedding group. After treatment, the CAS score, the total score and item-scores of PAC-QOL, as well as the TCM syndrome score in the thread-embedding group were lower than those in the Chinese patent medication group (P<0.05). The total effective rate was 78.9% (30/38) in the thread-embedding group, which was higher than 56.4% (22/39) in the Chinese patent medication group (P<0.05). CONCLUSION Thread-embedding at the combined lower he-sea and front-mu points can effectively treat functional constipation with intestinal excess heat and improve quality of life.

OBJECTIVE: To observe the effects of thumbtack-needle embedding therapy of auricular acupuncture on gastrointestinal function and intestinal microflora in the patients with gastric cancer after operation, and to explore its mechanism. METHODS: A total of 80 patients with gastric cancer after radical operation were randomly divided into an observation group (40 cases, 3 cases discontinued) and a control group (40 cases, 3 cases discontinued). The patients of both groups received the perioperative care for accelerating recovery. Additionally, in the observation group, the thumbtack-needle embedding therapy of auricular acupuncture was delivered at the auricular points of unilateral side, including Wei (CO₄), Pi (CO₁₃), Dachang (CO₇), Xiaochang (CO₆), Yuanzhong (AT_2,3,4i), Erzhong (HX₁), Sanjiao (CO₁₇) and Jiaowozhong (TF₃), and the needles were embedded and retained for 72 h. The postoperative recovery time of gastrointestinal function (the postoperative bowel sound recovery time, the first exhaust time, the first defecation time), the postoperative hospital stay and pain visual analogue scale (VAS) score were observed in the two groups. Before operation and on day 5 after operation, the serum gastrin level was detected in the two groups. The third-generation 16S rRNA sequencing technology was used to detect the composition and relative abundance of intestinal flora in the two groups before and after operation. RESULTS: Compared with the control group, the postoperative bowel sound recovery time, the first exhaust time and the first defecation time were shortened in the observation group (P<0.05). In the observation group, the VAS scores at 24 h, 48 h, and 72 h after surgery were lower than those of the control group, respectively (P<0.05). There was no significant differences in postoperative hospital stay and serum gastrin level between the two groups (P>0.05). The alpha diversity analysis showed that the differences in Shannon index, Simpson index, Pielou_J index and Pd_fath index were not significant statistically after intervention between the two groups (P>0.05). After intervention, the community structure of the fecal sample was similar at each taxonomic level between the two groups, and although the proportion between species was various, the difference was not significant (P>0.05). After intervention, there were 55 species with the differences between the two groups, 17 species of them presented significant difference in relative abundance in the observation group and 38 species in the control group. Regarding the level of genus, the levels of Klebsiell and Enterobacter increased (P<0.05) and the level of Streptococcus decreased (P<0.05) in the observation group. The main microbial groups that played an important role were Coprobacillaceae, Sutterellaceae and Yersiniaceae in the observation group. KEGG function prediction indicated that the function of intestinal microflora was mainly associated with the cofactor and vitamin metabolism, carbohydrate metabolism, and amino acid metabolism. CONCLUSION The thumbtack-needle embedding therapy of auricular acupuncture improves the postoperative gastrointestinal function of the patients with gastric cancer probably through regulating the structure and relative abundance of intestinal microflora and affecting the energy metabolism.

OBJECTIVE: To observe the distribution characteristics of sensitization areas on the body surface in the rat models with functional constipation and diarrhea, explore the regulatory patterns of electroacupuncture (EA) of different intensities at "Tianshu" (ST25) on distal colon motility, and clarify the roles of the neurons of different subtypes in the enteric nervous system (ENS) displayed in the regulatory effect. METHODS: Of 90 SD male rats of SPF grade, 15 rats were randomized into a normal group, a constipation group and a diarrhea group, 5 rats in each one. The stool form and fecal water content, as well as the distribution of the Evans blue (EB) extravasation on the body surface after the intravenous injection with EB on the tails were observed. Eighteen rats were randomized into a normal +2 mA group, a normal +4 mA group and a normal + 6 mA group, 6 rats in each one. Using physiological signal acquisition system, the area under the curve and the average amplitude of colon peristalsis were recorded and analyzed, and the immediate effect on distal colon peristalsis observed after EA with different intensities at "Tianshu" (ST25). Thirty rats were randomized into a normal group, a constipation group, a diarrhea group, a constipation +2 mA group, and a diarrhea +6 mA group, 6 rats in each one, so as to observe the cumulative effect on colon motility disorder in the rat models of constipation and diarrhea after EA at "Tianshu" (ST25). Twelve rats were randomized into a constipation +2 mA group and a diarrhea +6 mA group, 6 rats in each one, to observe the immediate effect on colon motility disorder in the rat models of constipation and diarrhea after EA at "Tianshu" (ST25). Fifteen rats were randomly divided into a normal group, a constipation group, a diarrhea group, a constipation +2 mA group, and a diarrhea + 6 mA group, 3 rats in each one. Using the whole-mount staining technique, the expression of vesicular acetylcholine transporter (VAChT)-positive neurons and nitric oxide synthase (nNOS)-positive neurons in ENS was detected. According to the group divisions, the functional constipation models were established by intragastric administration of loperamide hydrochloride (10 mg/kg, once daily, for consecutive 7 days), and the functional diarrhea models were prepared by intragastric administration of folium sennae decoction (10 mL/kg, once daily, for consecutive 2 days). The interventions were delivered with EA of different intensities (the electric current of 2, 4 or 6 mA) at bilateral "Tianshu" (ST25), separately, with the continuous wave and the frequency of 10 Hz used. RESULTS: Compared with the normal group, the fecal amount was decreased, and the fecal water content was reduced in the rats of the constipation group (P<0.001); and loose stool was presented and the fecal water content increased in rats of the diarrhea group (P<0.001). EB extravasation on the body surface happened in the region from T₆ to S₂ of the rats in the constipation and diarrhea groups, and it was more concentrated in the lower abdominal and the lower back regions from T₁₀ to L₃. Compared with the indexes before EA, in the normal +2 mA group and the normal +4 mA group, the areas under the curve and the average amplitude of the distal colon peristalsis were higher during EA delivery (P<0.01, P<0.05), showing a stimulatory immediate effect; and the post-effect was obtained after EA at 2 mA. Whereas, these two indexes were declined during EA in the rats of the normal +6 mA group (P<0.001), showing an inhibitory immediate effect. After many interventions with EA, when compared with those before EA, the above two indexes rose in the constipation +2 mA group (P<0.05, P<0.01), and they were dropped in the diarrhea +6 mA group (P<0.01, P<0.05). The area under the curve of the colon peristalsis in the constipation +2 mA group was higher than that of the constipation group (P<0.001), and that in the diarrhea +6 mA group was lower compared with that in the diarrhea group (P<0.001). The stimulatory effect of EA on colon motility in the constipation +2 mA group was stronger than that of the normal + 2 mA group (P<0.05), and its inhibitory effect was not different statistically in comparison between the normal +6 mA group and the diarrhea +6 mA group (P>0.05). In ENS of the distal colon, after EA at 2 mA, the proportion of VAChT-positive neurons was higher than that of the activated nNOS-positive neurons (P<0.001); and after EA at 6 mA, the activated nNOS-positive neurons were dominant (P<0.001). CONCLUSION In the functional constipation and diarrhea rat models, the sensitization areas on the body surface are centralized in the lower abdominal and the lower back regions of T₁₀ to L₃. Electroacupuncture at "Tianshu" (ST25) has a bidirectional regulatory effect on distal colon motility, and this effect is coordinated with the intensity of electroacupuncture, and may be mediated by ENS neurons of different subtypes.

OBJECTIVE: To observe the effects of electroacupuncture (EA) at changbing fang (prescription for intestinal disease) on autophagy of colonic cells and gut microbiota in rats with ulcerative colitis (UC), and to explore the mechanism of EA in the treatment of UC. METHODS: Thirty-two SD male rats were randomly divided into a control group, a model group, an EA group and a sham-EA group, with 8 rats in each group. Except the control group, the UC rat model was established by free drinking of 5% dextran sulfate sodium solution for 7 days in the other groups. In the EA group, changbing fang was adopted, in which, EA was applied at "Tianshu" (ST25) and "Shangjuxu" (ST37), at disperse-dense wave and frequency of 10 Hz/50 Hz, for 20 min in each intervention. In the sham-EA group, shallow transcutaneous puncture was performed at the sites, 5 mm away from the points as the EA group, with the same parameters as the EA group. The intervention was delivered once daily for 3 consecutive days. The body weight was measured daily and the disease activity index (DAI) score was calculated before and after intervention. After intervention completion, the colon length was measured. Using HE staining, the colon morphology was observed and the score of colonic pathology was assessed. With ELISA adopted, the contents of tumor necrosis factor (TNF-α), interleukin (IL)-1β, IL-2 and IL-10 in the serum of the rats were detected. The ultrastructure of the colon tissue was observed under electron microscopy. Using Western blotting, the protein expression was detected for microtubule-associated protein 1 light chain 3 (LC3)Ⅱ, LC3Ⅰ, autophagy-related genes (ATG) 5, ATG12, sequestosome 1 (p62), phosphatidylinositol 3-kinase (PI3K), phosphorylated protein kinase B (p-AKT), protein kinase B (AKT), and phosphorylated mammalian target of rapamycin (p-mTOR), mammalian target of rapamycin (mTOR) in the colon tissue. The mRNA expression of PI3K, AKT and m-TOR in the colon tissue was detected by real-time fluorescence quantitative PCR. The 16S rRNA gene sequencing was used to analyze the structure of gut flora in the feces of rats. RESULTS: From day 1 to day 7, compared with the control group, the body weight decreased in the model group, EA group, and SEA group (P<0.05, P<0.01). From day 9 to day 10, the EA group showed an increase in body weight compared with the model group and SEA group (P<0.05, P<0.01). Before intervention, the DAI score in the model group, EA group, and SEA group was higher than the score of the control group, respectively (P<0.01). After intervention, the DAI score in the EA group was reduced compared with the model group and SEA group (P<0.01). Compared with the control group, in the model group, the colon length of rats was shorter (P<0.01); it showed the distorted crypts, thinner mucosal layer, reduced goblet cells, inflammatory cell infiltration and the disarranged histological structure; and the pathological score of the colon tissue increased (P<0.01); the serum contents of TNF-α and IL-1β increased (P<0.01), and those of IL-2 and IL-10 decreased (P<0.01). The structure of colon epithelial cells was disarranged, with cilia pelt off, and a large number of vacuoles in the cytoplasm; the mitochondria were swollen, with unclear structure and cristae partially disappeared; and few autophagosomes were observed. The value of LC3Ⅱ/LC3Ⅰand the protein expression of ATG5 and ATG12 in the colon tissues were reduced (P<0.01), the protein expression of p62 and PI3K, and the values of p-AKT/AKT, and p-mTOR/mTOR increased (P<0.01), and mRNA expression of PI3K, AKT and mTOR was elevated (P<0.01). The indexes of Chao1, Ace and Shannon decreased (P<0.01). At the phylum level, the relative abundance of Firmicutes decreased (P<0.05), that of Bacteroidetes and Proteobacteria increased (P<0.05, P<0.01). At the genus level, the relevant abundance of Lactobacillus decreased (P<0.05), while that of Lachnospiraceae_NK4A136_group and Phascolarctobacterium increased (P<0.01, P<0.05 ). Compared with the model group and SEA group, in the EA group, the colon length increased (P<0.01), the infiltration of inflammatory cells was reduced, the arrangement of intestinal epithelial cells was arranged regularly, with a small amount of shedding, and the pathological score of the colon tissue decreased (P<0.01). The serum contents of TNF-α and IL-1β decreased (P<0.01), and those of IL-2 and IL-10 increased (P<0.01). The colonic epithelial cells were arranged relatively, the morphology of organelles was basically normal, and autophagosomes were visible. The value of LC3Ⅱ/LC3Ⅰand the protein expression of ATG5 and ATG12 in colon tissue increased (P<0.01, P<0.05), the protein expression of p62 and PI3K, and the values of p-AKT/AKT, and p-mTOR/mTOR decreased (P<0.01); and mRNA expression of PI3K, AKT, m-TOR was reduced (P<0.01). The indexes of Chao1, Ace and Shannon increased (P<0.01). At the phylum level, the relative abundance of Firmicutes increased (P<0.01), while that of Bacteroidetes decreased (P<0.01). At the genus level, the relative abundance of Lactobacillus increased (P<0.05), whereas that of Lachnospiraceae_NK4A136_group decreased (P<0.01). When compared with the model group, the relative abundance of Proteobacteria decreased (P<0.05), and that of Phascolarctobacterium was reduced (P<0.05) in the EA group. CONCLUSION EA at changbingfang alleviates UC symptoms probably through inhibiting the PI3K/AKT/mTOR signaling pathway to regulate colonic autophagy and improve the intestinal flora.

OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.
