Objective:To explore the clinical characteristics and identification of the independent risk factors for disease progression in patients with anti-gp210 antibody-positive primary biliary cholangitis (PBC).Methods:A retrospective cohort study was performed. A total of 323 cases with PBC diagnosed in Tianjin Medical University General Hospital from January 2013 to June 2023 (125 patients with anti-gp210 antibody-positive and 198 patients with anti-gp210 antibody-negative) were included. Baseline and follow-up data were collected. The independent sample t-test and Mann-Whitney U rank sum test were used for comparison between groups of continuous data. The χ2 test was used to compare the data between groups for the count data. The Pearson test was used for correlation analysis between continuous variables. The Kaplan-Meier method was used to analyze the disease progression-free survival rate. The Cox regression model was used to analyze the risk factors for disease progression. Results:The male proportion (11.2% vs. 5.1%, P=0.040) and IgM level [3.29(1.88, 4.80) g/L vs. 2.56(1.44, 3.87) g/L, P=0.019] were significantly higher in patients with PBC with positive anti-gp210 antibodies than those of the negative group. Histopathological analysis showed that the Scheuer score [1(0,3) vs. 0(0,2)], bile duct inflammation [(2(1,3) vs. 1(1,2)] and bile duct reaction score [(2(1,3) vs. 1(1,2)] were higher in the positive group than those of the negative group ( P<0.05), and the maturity of the tertiary lymphoid structure was higher ( P=0.011). Kaplan-Meier analysis showed that the 5-year disease-free survival rate was significantly lower in patients with positive anti-gp210 antibodies than that of the negative group (55.8% vs. 79.7%, P=0.006) at a median follow-up of 3(2,6) years. Multivariate Cox regression analysis showed that γ-glutamyl transferase [ HR=1.002 (95% CI: 1.000～1.003)] and platelet count [ HR=0.993 (95% CI: 0.988～0.999)] were the independent influencing factors for disease progression in patients with anti-gp210 antibody-positive PBC ( P=0.002, 0.017). Conclusion:Patients with anti-gp210 antibody-positive PBC have more severe clinical pathological manifestations and a higher risk of disease progression. Higher levels of γ-glutamyl transferase and lower platelet counts during the first visit are independent risk factors for disease progression in patients with anti-gp210 antibody-positive PBC, which can be used as dynamic monitoring indicators for this population, suggesting the need for early intensive intervention.

Objective:To analyze the clinical characteristics，laboratory tests，endoscopic features，treatment，and follow-up of peptic ulcers caused by eosinophilic gastrointestinal disorders（EGIDs）in children，with the aim of improving the level of understanding，diagnosis and treatment of EGIDs in children with the onset of peptic ulcers.Methods:A retrospective analysis was conducted on children admitted to the Department of Gastroenterology，Capital Center for Children's Health，Capital Medical University from January 1st，2019 to October 31st，2023，who underwent complete endoscopic examination. The first examination showed the presence of peptic ulcers（gastric or duodenal ulcers）under the endoscope，and were ultimately diagnosed with peptic ulcers caused by EGIDs through examination and follow-up. The clinical characteristics，laboratory tests，endoscopic results，and treatment follow-up were analyzed.Results:Thirty-five children were EGIDs，22 males and 13 females.Twenty-two cases（62.9%）had abdominal pain as the main symptom.Laboratory tests：17 cases（48.6%）showed a decrease in hemoglobin，15 cases（42.9%）showed an increase in eosinophil count，20 cases（57.1%）tested gastro positive for food allergen specific IgE，and 17 cases（48.6%）showed thickening of the intestinal wall on gastrointestinal ultrasound. Endoscopic features：8 cases（22.9%）showed gastric antral ulcers，including 7 cases（20.0%）with multiple gastric antral ulcers，and 25 cases（71.4%）showed duodenal bulb ulcers.There were 15 cases（42.9%）showed huge ulcers，and 14 cases（40.0%）were located in the duodenal bulb. Comparison of clinical characteristics between children with EGIDs（EGIDs group）and those with peptic ulcers caused by Helicobacter pylori infection（Hp group）：the first clinical symptom in both groups was mainly abdominal pain，but the incidence rate in the EGIDs group was lower（62.9% vs 93.5%），and the weigth for length Z score in the EGIDs group was lower［0（-1.6，0.8）vs 1.1（0，1.9）］，with statistical significance（all P<0.05）. Comparison of laboratory tests：the EGIDs group showed a statistically significant difference in hemoglobin levels［120（101，124）g/L vs 130（100，138）g/L］，eosinophil count［0.28（0.13，0.71）× 10 9/L vs 0.16（0.08，0.22）×10 9/L］，a positive rate of food allergen specific IgE detection（57.1% vs 32.3%），and a positive rate of intestinal wall thickening detected by gastrointestinal ultrasound（48.6% vs 16.1%）compared with the Hp group（all P<0.05）. Comparison of endoscopic examinations：multiple ulcers in the gastric antrum were more common in the EGIDs group than in the Hp group（20.0% vs 0），and the difference was statistically significant（ P<0.05）. Conclusion:For children with peptic ulcers with onset of abdominal pain，with anemia or malnutrition，or multiple ulcers in the gastric antrum and huge ulcers in the duodenal bulb detected by endoscopy，it is recommended to perform multi site biopsies to help diagnose EGIDs early.

OBJECTIVE: The study aim was to investigate the effects of exposure to multiple environmental organic pollutants on cardiopulmonary health with a focus on the potential mediating role of oxidative stress. METHODS: A repeated-measures randomized crossover study involving healthy college students in Beijing was conducted. Biological samples, including morning urine and venous blood, were collected to measure concentrations of 29 typical organic pollutants, including hydroxy polycyclic aromatic hydrocarbons (OH-PAHs), bisphenol A and its substitutes, phthalates and their metabolites, parabens, and five biomarkers of oxidative stress. Health assessments included blood pressure measurements and lung function indicators. RESULTS: Urinary concentrations of 2-hydroxyphenanthrene (2-OH-PHE) ( β = 4.35% [95% confidence interval ( CI): 0.85%, 7.97%]), 3-hydroxyphenanthrene ( β = 3.44% [95% CI: 0.19%, 6.79%]), and 4-hydroxyphenanthrene (4-OH-PHE) ( β = 5.78% [95% CI: 1.27%, 10.5%]) were significantly and positively associated with systolic blood pressure. Exposures to 1-hydroxypyrene (1-OH-PYR) ( β = 3.05% [95% CI: -4.66%, -1.41%]), 2-OH-PHE ( β = 2.68% [95% CI: -4%, -1.34%]), and 4-OH-PHE ( β = 3% [95% CI: -4.68%, -1.29%]) were negatively associated with the ratio of forced expiratory volume in the first second to forced vital capacity. These findings highlight the adverse effects of exposure to multiple pollutants on cardiopulmonary health. Biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine and extracellular superoxide dismutase, mediated the effects of multiple OH-PAHs on blood pressure and lung function. CONCLUSION Exposure to multiple organic pollutants can adversely affect cardiopulmonary health. Oxidative stress is a key mediator of the effects of OH-PAHs on blood pressure and lung function.

Objective:To explore the clinical and genetic characteristics and follow-up status of pediatric patients with hepatic glycogen storage disease in order to further improve the prognosis.Methods:The clinical data of hospitalized children diagnosed with hepatic glycogen storage disease in the Department of Gastroenterology at the Children's Hospital of Capital Institute of Pediatrics from January 2010 to April 2023 were collected and retrospectively analyzed. The results of laboratory examination and gene sequencing were analyzed, and the number of cases that exceeded three (n) were grouped according to the genetic results: Group 1 was type Ⅰ ( n=8), Group 2 was type Ⅲ ( n=5), and Group 3 was type Ⅸa ( n=8).The growth, development and prognosis of the children were followed up. The related clinical characteristics of pediatric hepatic glycogen storage disease were summarized. Results:Twenty-five pediatric patients with hepatic glycogen storage disease were enrolled in this study, with fifteen males and ten females. The mean age of diagnosis was (29.1±13.5) months. There were twelve cases (48%) accompanied with varying degrees of hypoglycemia, and two cases (8%) with severe hypoglycemia.There were nineteen cases with stature retardation (76%), four cases with anemia (16%), three cases with proteinuria (12%), and one case with cholestasis (4%).The genetic results showed that there were four cases of type Ⅰa (16%), four cases of type Ⅰb (16%), one case of type Ⅱ (4%), five cases of type Ⅲ (20%), two cases of type Ⅳ (8%), one case of type Ⅵ (4%), and eight cases of type Ⅸ (32%).The three subgroups analysis showed that there were significant statistical differences in uric acid and triglycerides among the three groups ( P<0.05), while there were no statistical significant differences in transaminase levels, fasting blood glucose, lactate, cholesterol, and low-density lipoprotein levels ( P>0.05). The height-for-age Z scores of the three groups were -2.86±1.62, -1.46±1.06, and -1.83±0.98, respectively. The growth and development of groups 2 and 3 were significantly improved compared with group 1 ( P<0.05), with Z scores of -2.28±1.07, 0.20±1.54, and 0.10±1.44 after at least one year of follow-up. All pediatric patients with type Ⅸa had discontinued using raw corn starch after more than one year of follow-up and their transaminases had returned to normal. Four pediatric patients with type Ia were orally administered raw corn starch on a regular basis, and the aminotransferases, uric acid, and lactate were normal, with hypoglycemia being monitored. Among the four cases with type Ⅰb, one had recurrent respiratory tract and intestinal infections, two were combined with Crohn's disease, and one was monitored for hypoglycemia. In four cases of type Ⅲ, raw corn starch was discontinued, and a high-protein, low-carbohydrate diet was adopted, with the exception of the presence of high creatine kinase and normal aminotransferase. Liver failure resulted in the death of one type Ⅵ case, while two were type Ⅳ cases; one died, and one case recently had slightly elevated aminotransferase. Conclusion:When pediatric patients exhibit manifestations such as hepatomegaly, elevated transaminases, fasting hypoglycemia, and delayed growth and development, it is necessary to be alert to hepatic glycogen storage disease. Clinical manifestations and biochemical indicators combined with genetic testing are helpful for the diagnosis of hepatic glycogen storage disease. Simultaneously, targeted nutritional management should be carried out according to the metabolic characteristics of different subtypes, with attention on growth and development status.

Objective To explore relationship between glucose metabolism and neonatal weight in high-risk gestational diabetes melli-tus(GDM).Method A retrospective study was conducted on 779 pregnant women who underwent prenatal examinations at Tongzhou Maternity and Child Health Care Hospital in Beijing from March to June 2022.The data on pre-pregnancy weight,mid-and late-preg-nancy glycated albumin(GA)and glycated hemoglobin(HbA1c),pre-delivery weight,gestational weight gain,and neonatal birth weight were collected.A GDM risk assessment model was established using multivariate logistic regression to classify pregnant women into high-risk and low-risk groups for GDM,followed by separate management strategies.Regression discontinuity(RD)analysis was applied to evaluate the relationship between gestational glucose metabolism status and neonatal birth weight.Results Among the 779 pregnant women,the overall incidence of macrosomia was 7.32％.The high-risk GDM group exhibited significantly higher pre-pregnan-cy weight,late-pregnancy HbA1c,and GA levels compared to the low-risk group(all P＜0.001).Neonatal birth weight in the high-risk group was significantly higher than that in the low-risk group(P＜0.05),with a significantly increased macrosomia incidence(13.55％vs 5.77％,P＜0.05).RD analysis revealed a jump reduction of 199.59 g(P=0.029)in neonatal birth weight at the risk score thresh-old.Conclusion Lifestyle glucose metabolism management in high-risk GDM pregnant women may effectively reduce neonatal birth weight,mitigated the trend of excessive gestational weight gain,and improved late-pregnancy HbA1c and GA levels,providing evi-dence-based support for maternal and child health services.

Objective:To explore the effect of ezetimibe combined with atorvastatin on the efficacy,blood lipids,ca-rotid ultrasound indicators in patients with coronary heart disease(CHD)and its safety.Methods:This randomized controlled study enrolled 98 CHD patients admitted to 945th Hospital of the PLA Joint Logistic Support Force be-tween June 2021 and June 2023.Patients were divided into intervention group and control group with 49 cases in each group.Patients in the control group was treated with atorvastatin-bascd routine medication comparing to those in intervention group receiving additional ezetimibe,both groups were treated for 90 d.Clinical efficacy,blood lipids,carotid ultrasound indicators,endothelial function indicators,and incidence of adverse reactions were compared between two groups.Results:Compared with patients in the control group,those in the intervention group had significant higher total effective rate(91.83％vs.73.47％,P=0.016).Compared with patients in the control group after treatment,those in intervention group had significant lower levels of low density lipoprotein cho-lesterol(LDL-C)[(2.74±0.61)mmol/L vs.(3.42±0.66)mmol/L],total cholesterol(TC)[(3.80±0.89)mmol/L vs.(4.69±1.02)mmol/L],triglyceride(TG)[(1.79±0.53)mmol/L vs.(2.35±0.62)mmol/L],re-sistance index(RI)[(52.02±6.32)％vs.(57.95±6.02)％],carotid intima-media thickness(IMT)[(0.91±0.17)mm vs.(1.08±0.24)mm],von Willebrand factor(vWF)[(19.03±3.76)mg/L vs.(23.41±4.42)mg/L],angiotensin Ⅱ(Ang Ⅱ)[(45.83±5.87)ng/L vs.(52.87±6.01)ng/L](P＜0.001 all);and significant high-er high density lipoprotein cholesterol(HDL-C)[(1.63±0.32)mmol/L vs.(1.35±0.27)mmol/L],peak systol-ic velocity(PSV)[(47.93±5.26)cm/s vs.(41.32±4.98)cm/s],end-diastolic velocity(EDV)[(36.14±5.10)cm/s vs.(30.73±4.48)cm/s],pulse index(PI)[(85.98±9.03)％vs.(78.42±8.82)％],vascular endothelial growth factor receptor 1(VEGFR1)[(289.14±32.98)ng/L vs.(258.34±29.32)ng/L](P＜0.001 all).There was no significant difference in the incidence of adverse reactions between the two groups(P=0.538).Conclusion:Ezetimibe combined with atorvastatin possesses significant therapeutic effect on CHD patients,which could signifi-cantly reduce blood lipids,improve the carotid blood flow velocity and vascular endothelial function with good safety.

Objective:To explore the perioperative safety and postoperative efficacy of prophylactic jejunal nutrition tube placement during early gastric body cancer pylorus-preserving gastrectomy (PPG).Methods:The clinical data of 29 gastric cancer patients treated by Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2024 were retrospectively analyzed. There were 17 males (58.6%) and 12 females (41.4%), aged from 43 to 74 years, with an average age of (58.9 ± 8.3) years, and an average body mass index (BMI) of (24.3 ± 3.0) kg/m 2. According to the type of catheterization, all cases were divided into jejunal nutrition tube group ( n=12) and gastric tube group( n=17). The main outcome was the incidence of delayed gastric emptying within one month after surgery in both groups. Statistical analysis was conducted using SPSS26.0 software. Results:Patients in the jejunal feeding tube group resumed oral liquid intake, soft diet and regular diet significantly earlier postoperatively compared to those in the gastric tube group, with statistically significant differences ( P<0.05). Conversely, the time to removal of the tube was significantly earlier in the gastric tube group than in the jejunal feeding tube group ( P<0.05). However, the proportion of patients requiring reinsertion of a gastric or jejunal feeding tube postoperatively was significantly higher in the gastric tube group (7 cases) compared to the jejunal feeding tube group (0 case) ( P<0.05). In the jejunal feeding tube group, there were 4 cases occurred DGE, in the gastric tube group, there were 8 cases occurred DGE. There were no statistically significant differences between the two groups in either the overall incidence of DGE or the distribution of DGE severity grades. On postoperative 7th day , the Gastric Outlet Obstruction Scoring System (GOOSS) grade was significantly better in the jejunal feeding tube group than in the gastric tube group ( P<0.05), and all patients in the jejunal feeding tube group had resumed liquid intake, compared to only 58.8% in the gastric tube group. Conclusions:Compared with gastric tube placement, intraoperative prophylactic jejunal feeding tube placement for PPG has significant advantages in perioperative safety and postoperative recovery, but large-sample prospective studies are still needed for further verification.

Objective To investigate the effect of simple carbohydrate given 2 h before operation on postoperative insulin resistance and gastrointestinal function in elderly patients with trauma undergoing spinal anesthesia.Methods This was a randomized controlled clinical study.A total of 90 elderly patients with intertrochanteric femoral fracture/femoral neck fracture admitted to the Traumatic Orthopedics Department of the Fourth Medical Center of Chinese PLA General Hospital from October 2023 to February 2024 were randomly divided equally into control group(fasting with water before surgery)and carbohydrate group(CHO group,drinking 200 ml of pulsatile water at 2 h before surgery).All the patients received spinal anesthesia.The control group excluded 2 patients who completed surgery and were admitted to the ICU,2 patients received epidural anesthesia,and finally included 41 patients;3 patients were excluded from the CHO group under epidural anesthesia,2 patients underwent surgery under general anesthesia,and finally 40 patients were included.Baseline data of patients were collected,including gender,age,Charlson comorbidity index(CCI),presence or absence of diabetes,body mass index(BMI),American Association of Anesthesiologists(ASA)classification,etc.The patient's surgical time,intraoperative blood loss,first postoperative exhaust time,type of surgery,length of hospital stay,mean arterial pressure(MAP)and heart rate(HR)at four time points during surgery[entry(T1),post-anesthesia(T2),mid-operation(T3),and exit(T4)],perioperative blood glucose,insulin levels,C-reactive protein(CRP),and intestinal barrier function indicators(diamine oxidase,D-lactate,and bacterial endotoxin),as well as self-rating anxiety scale(SAS),visual analogue scale of pain(VAS),and Ramsay scores were recorded.Preoperative and postoperative use of the delirium diagnostic scale(3D-CAM)assessed the presence of delirium in patients.Results Eighty-one patients aged(77.7±9.5)years were included.Compared with control group,the first exhaust time in CHO group was significantly shorter[4.59(3.25,7.39)h vs.10.23(7.97,14.76)h,P<0.001],postoperative insulin resistance index(HOMA-IR)was significantly decreased[5.13(2.38,10.30)vs.7.34(2.31,12.55),P<0.001].The change rate of HOMA-IR(ΔHOMA-IR)also decreased significantly(P<0.001);There were no significant differences in intestinal barrier function indexes between the two groups(P>0.05);The levels of D-lactic acid and bacterial endotoxin in control group were significantly increased after operation,and the differences were statistically significant(P=0.010,P=0.031),In CHO group,there was no significant difference in preoperative and postoperative indexes(P>0.05).There was no significant difference in the perioperative scale score,incidence of delirium and the length of hospital stay between the two groups(P>0.05).Conclusions Taking simple carbohydrates 2 h before surgery can significantly shorten the first exhaust time,reduce insulin resistance and the incidence of delirium,and improve gastrointestinal function in elderly trauma patients undergoing spinal anesthesia,thus providing clinical basis for accelerated postoperative rehabilitation in elderly patients.
