Intestinal fibrosis is a significant clinical challenge in inflammatory bowel diseases, but no effective anti-fibrotic therapy is currently available. Glucagon receptor (GCGR) and glucagon-like peptide 1 receptor (GLP1R) are both peptide hormone receptors involved in energy metabolism of epithelial cells. However, their role in intestinal fibrosis and the underlying mechanisms remain largely unexplored. Herein GCGR and GLP1R were found to be reduced in the stenotic ileum of patients with Crohn's disease as well as in the fibrotic colon of mice with chronic colitis. The downregulation of GCGR and GLP1R led to the accumulation of the metabolic byproduct lactate, resulting in histone H3K9 lactylation and exacerbated intestinal fibrosis through epithelial-to-mesenchymal transition (EMT). Dual activating GCGR and GLP1R by peptide 1907B reduced the H3K9 lactylation in epithelial cells and ameliorated intestinal fibrosis in vivo. We uncovered the role of GCGR/GLP1R in regulating EMT involved in intestinal fibrosis via histone lactylation. Simultaneously activating GCGR/GLP1R with the novel dual agonist peptide 1907B holds promise as a treatment strategy for alleviating intestinal fibrosis.

Amyloidosis is a rare disease.This paper reports a case of localized secondary hypopharyngeal amyloidosis presenting with pulmonary tuberculosis as the initial symptom.The patient lacked specific clinical manifestations and primarily exhibited symptoms such as cough,sputum production,acid reflux,belching,and abdominal pain.Chest CT indicated bronchiectasis with infection and pulmonary tuberculosis.Digestive endoscopy revealed a white mucosal elevation at the right pyriform sinus of the hypopharynx.Pathological diagnosis confirmed amyloid deposits in the hypopharyngeal mucosal tissue.The patient tested positive for anti-amyloid A antibodies,Congo red staining(+),and periodate Schiff staining(+).Amyloidosis commonly affects the digestive system and may have various etiologies,often presenting with symptoms that overlap with other digestive system diseases,leading to frequent misdiagnosis and missed optimal treatment opportunities.The hypopharynx,a highly folded and narrow chamber that serves as a common passage for the digestive and respiratory tracts,can be effectively evaluated for amyloidosis using digestive endoscopy.

Objective:To investigate the incidence and risk factors of deep vein thrombosis(DVT)in patients with rheumatoid arthritis(RA).Methods:The clinical data of RA patients who were hospi-talized in the Department of Rheumatology and Immunology of Aerospace Center Hospital from May 2015 to September 2021 was retrospectively analyzed,including demographic characteristics,concomitant diseases,laboratory examinations(blood routine,biochemistry,coagulation,inflammatory markers,rheumatoid factor,antiphospholipid antibodies and lupus anticoagulant,etc.)and treatment regimens.The patients were compared according to the presence or absence of DVT,and the t test,Mann-Whitney U test or Chi-square test were applied to screen for relevant factors for DVT,followed by Logistic regres-sion analysis to determine risk factors for DVT in patients with RA.Results:The incidence of DVT in the RA patients was 9.6％(31/322);the median age of RA in DVT group was significantly older than that in non-DVT group[64(54,71)years vs.50(25,75)years,P＜0.001];the level of disease activity score using 28 joints(DAS28)-erythrocyte sedimentation rate(ESR)in DVT group was higher than that in non-DVT group[5.2(4.5,6.7)vs.4.5(4.5,5.0),P＜0.001];the incidence of hypertension,chronic kidney disease,fracture or surgery history within 3 months,and varicose veins of the lower ex-tremities in DVT group was higher than that in non-DVT group(P＜0.001).The levels of hemoglobin and albumin in DVT group were significantly lower than that in non-DVT group(P=0.009,P=0.004),while the D-dimer level and rheumatoid factor positive rate in DVT group were significantly higher than that in non-DVT group(P＜0.001).The use rate of glucocorticoid in DVT group was higher than that in non-DVT group(P=0.009).Logistic regression analysis showed that the age(OR=1.093,P＜0.001),chronic kidney disease(OR=7.955,P=0.005),fracture or surgery history with-in 3 months(OR=34.658,P=0.002),DAS28-ESR(OR=1.475,P=0.009),and the use of glu-cocorticoid(OR=5.916,P=0.003)were independent risk factors for DVT in RA patients.Conclu-sion:The incidence of DVT in hospitalized RA patients was significantly increased,in addition to tradi-tional factors,such as age and chronic kidney disease,increased DAS28-ESR level and the use of glu-cocorticoid were also independent risk factors for DVT.

Objective:To evaluate the therapeutic effect of glycyrrhetinic acid on cough variant asthma (CVA) mice based on molecular docking technique; To explore the possibility of its treatment for cough variant asthma.Methods:The software of Autodock Vina was used for molecular docking. The mice were divided into control group, model group, prednisone acetate group, glycyrrhetinic acid high-, medium-, and low-dosage groups according to the random number table method, with 8 mice in each group. Except for the blank control group, all other groups were induced by egg protein to establish cough variant asthma models. Glycyrrhetinic acid high-, medium-, and low-dosage groups were orally administered glycyrrhetinic acid suspension at 20, 10, and 5 mg/kg, while the prednisone acetate group was orally administered prednisone acetate at 5 mg/kg. The blank control group and model group were orally administered equal volumes of physiological saline, once per day for 14 consecutive days. The animal asthma behavior was observed after drug administration. The secretion of bronchial mucus in lung tissue were observed by AB-PAS staining and the index of spleen were recorded. The protein expressions of Gata3, IL-4 and IL-13 in the spleen tissue were determined by Western blot.Results:Molecular docking results showed that glycyrrhetinic acid had good binding ability to Th2-related factors Gata3, IL-4 and IL-13. Results of animal experiment showed that compared with the model group, the mucus secretion decreased in glycyrrhetinic acid groups, the index of the spleen of mice obviously decreased, protein expression levels of IL-4 and IL-13 in the spleen tissue of mice in glycyrrhetinic acid high-, medium-, and low-dosage groups decreased ( P<0.05), and Gata3 in glycyrrhetinic acid medium- and low-dosage groups decreased ( P<0.05). Conclusion:Glycyrrhetinic acid can correct the shift of Th2 in the immune system of cough variant asthma mice and has a certain therapeutic effect.

Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE. Of 5 271 non-surgical patients, the incidence of VTE was 2.201%(116/5 271), including an incidence of 0.114%(6/5 271) of PE. PE accounted for 5.172%(6/116) of non-surgical patients with VTE. There was no significant difference in the incidence of VTE or PE between surgical patients and non-surgical patients ( χ2=1.20, 0.05, P>0.05). (2) Treatment and outcomes of patients with VTE. Among 175 EC patients with VTE, 163 cases underwent drug treatment, and 12 cases did not receive treatment. Among 163 cases with drug therapy, 158 cases underwent anticoagulant therapy, 5 cases were treated with thrombolysis. All the 163 patients were improved and discharged from hospital. Conclusions:The incidence of VTE in patients with EC is relatively low, as 2.069%. There is no significant difference in the incidence of VTE or thrombus type between surgical EC patients and non-surgical EC patients.

The efficacy and safety of venetoclax combined with reduced dose HAD regimen in the treatment of newly diagnosed acute myeloid leukemia (AML) was investigated. From May 2022 to January 2023, a total of 25 patients with newly diagnosed AML were treated with venetoclax combined with reduced-dose HAD regimen as induction therapy. Accoding to the 2017 ELN recommendations, 13 (52.0%) in favoable, 3 (12.0%) in intemediate, and 9 (36.0%) in adverse. The ORR (CR rate+PR rate) was 88.0%, and the CR rate was 84.0%. By May 30, 2023, with a median follow-up of 9 months, 1 year overall survival, event-free survival, and relapse-free survival were 100%, 94.7%, and 94.7%, respectively. All patients received 1-5 cycles of consolidation therapy and two median cycles. Treatment with venetoclax and reduced dose of HAD regimen in the treatment of patients with newly diagnosed AML was high effective and safe.

Objective To compare the safety and efficacy of SpyGlass DS system laser lithotripsy and conventional fractional treatment under endoscopic retrograde cholangiopancreatography(ERCP)in treatment of large calculus of common bile duct.Method 38 patients with large calculus of common bile duct(>2 cm)during ERCP from November 2021 to October 2023 were selected and divided into experimental group(n=18)and control group(n=20).The experimental group was treated with SpyGlass DS system combined with laser lithotripsy.The patients in the control group were treated with split treatment(the first biliary stent was placed,and the calculus of common bile duct were removed under conventional ERCP again 3 months later).The success rate of stone clearance and the incidence of complications after ERCP were compared between the two groups.Magnetic resonance cholangiopancreatography(MRCP)was performed 3 months after surgery to determine whether there were residual calculus of common bile duct.Results The surgical time of the experimental group was longer than that of the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the stone clearance rate and the incidence of short-term complications between the two groups(P>0.05).The incidence of long-term complications in the experimental group was lower than that in the control group,but the difference was not statistically significant(P=0.090).Conclusion SpyGlass DS guided laser lithotripsy is effective and safe for the treatment of large calculus of common bile duct,with a low recurrence rate.

Objective:To analyze the application value of autophagy related molecular markers in placenta tissue in predicting fetal growth restriction in pregnant women with preeclampsia.Methods:A total of 46 pregnant women admitted to Changsha Hospital for Maternal and Child Health Care from January 2021 to August 2023 were collected. A cross-sectional study was conducted, and they were divided into a normal delivery group (control group, 23 cases) and an observation group with preeclampsia combined with fetal growth restriction (observation group, 23 cases) based on pregnancy outcomes. Transmission electron microscopy was used to observe the occurrence of autophagic vesicles in trophoblast cells in the placental tissue of both groups; The expression of Beclin-1, LC3, and P62 in placental tissues of two groups was detected by immunohistochemistry, real-time fluorescence quantitative polymerase chain reaction (qRT-PCR), and Western blot.Results:The transmission electron microscopy results showed that the presence of autophagic vesicles could be observed in the placental trophoblast cells of both the control group and the observation group, but the number of autophagic vesicles in the trophoblast cells of the observation group was higher than that in the control group ( P<0.05). The immunohistochemical results showed that the colorimetric values of Beclin-1 and LC3 in the placental tissue sections of the observation group were higher than those of the control group (all P<0.001), while the colorimetric values of p62 were lower than those of the control group ( P<0.001). The qRT-PCR and Western blot results showed that the mRNA and protein expression levels of Beclin-1 and LC3 in the observation group were significantly higher than those in the control group (all P<0.001), while the expression levels of p62 mRNA and protein were lower than those in the control group (all P<0.001). Conclusions:The autophagy activity of placental tissue trophoblasts in patients with preeclampsia combined with fetal growth restriction is enhanced, indicating a close correlation between elevated autophagy levels and the occurrence of preeclampsia combined with fetal growth restriction. Excessive autophagy may be involved in the occurrence of preeclampsia combined with fetal growth restriction.
