Gastrointestinal graft versus host disease is one of the most severe complications after hematopoietic stem cell transplantation, which can occur in patients of any age groups. Its clinical manifestations include nausea, vomit, abdominal pain, diarrhea and the like. Severe gastrointestinal graft versus host disease could directly influence the patients' clinical prognosis and therapeutic efficacy of transplantation. Here we had a review of the research progress on nutritional support and diet management strategies for gastrointestinal graft versus host disease. It is of great clinical significance to form a step-wise nutritional support model to reduce the risk of malnutrition in patients with gastrointestinal graft versus host disease, which would contribute to improving patients' general condition, relieving digestive tract symptoms, and reducing the risk of complications.

Objective To explore root cause of poor prognosis after successful endovascular treatment(EVT)in patients with acute ischemic stroke with large vascular occlusion(AIS-LVO)of anterior circulation.Methods Patients with AIS-LOV of anterior circulation who received successful EVT(postoperative modified thrombolysis incerebral infarction[mTICI]grade≥2b)were retrospectively and continuously collected in the Department of Neurology of Bozhou People's Hospital from January 2022 to March 2024.The baseline and clinical data of the patients were collected,including gender,age,vascular risk factors(hypertension,diabetes,coronary heart disease,hyperlipidemia,valvular heart disease,atrial fibrillation,smoking,and alcohol consumption),prior stroke or transient ischemic attack,baseline blood pressure,baseline National Institutes of Health Stroke scale(NIHSS)score,laboratory test indicators(pre-operative C-reactive protein and D-dimer,post-operative fasting blood glucose,lipid levels,homocysteine,etc).Meanwhile,the data of perioperative indicators was collected,including the time from onset to admission,the time from admission to puncture,the time from puncture to revascularization,the time from onset to puncture,the time from onset to revascularization,remedial measures(balloon dilation,stent placement,arterial thrombolysis)during the surgery or not,using tirofiban or not,postoperative complications(stroke-related pneumonia,stress ulcers,deep vein thrombosis,acute heart failure or renal failure,etc)or not.The patient's medical history and imaging data were collected,and these indicators were defined and collected,including Alberta stroke program early CT score(ASPECTS),location of occlusion(C1 segment of the internal carotid artery,C2 segment to C7 segment of the internal carotid artery,M1 segment of the middle cerebral artery),and the trial of org 10172 in acute stroke treatment(TOAST)classification and a postoperative transformation of cerebral infarction after ischemic stroke and symptomatic intracranial hemorrhage or not.According to the modified Rankin scale(mRS)score at 90 d after surgery,all patients were divided into poor prognosis group(mRS score≥ 3)and good prognosis group(mRS score≤2).The baseline and clinical data of two groups were compared using univariate analysis.Variables with P＜0.1 in the univariate analysis were selected as independent variables,and the poor prognosis was used as the dependent variable.Further,multivariate Logistic regression analysis was performed to identify the influencing factors of poor prognosis after EVT.Results Finally,a total of 192 patients with AIS-LVO of anterior circulation who received successful revascularization were included in this study.There were 101 male patients and 91 female patients.The poor prognosis group had 102 cases and the good prognosis group had 90 cases.Univariate analysis showed that the poor prognosis group had statistically significant differences with the good prognosis group in terms of age(Z=-3.088,P=0.002)and age distribution(x2=13.457,P=0.001),fasting blood glucose(Z=-3.347,P=0.001),baseline NIHSS score(Z=-4.469,P＜0.01),location of occlusion(x2=10.488,P=0.005),transformation of hemorrhage after ischemic stroke(x2=16.943,P＜0.01),and symptomatic intracranial hemorrhage(X2=25.449,P＜0.01),and the baseline ASPECTS of the poor prognosis group was significantly lower than that of the good prognosis group(Z=-4.547,P＜0.01).There were no significant differences in other baseline and clinical data(all P＞0.05).Further multivariate Logistic regression analysis showed that age＞80 years(OR,3.224,95％CI 1.033-10.058,P=0.044),baseline NIHSS score(OR,1.102,95％CI 1.013-1.199,P=0.023),baseline ASPECTS(OR,0.375,95％CI 0.212-0.665,P=0.001),and symptomatic intracranial hemorrhage(OR,7.127,95％CI 1.296-39.203,P=0.024)were independent influencing factors of poor prognosis.Conclusion The independent factors of 90 d poor prognosis after successful EVT in patients with AIS-LVO of anterior circulation are age＞80 years,baseline NIHSS score,baseline ASPECTS,and symptomatic intracranial hemorrhage.

Objective:To explore the correlation between defecation disorders and diet in patients undergoing sphincter-preserving surgery for rectal cancer.Methods:This study was a cross-sectional survey. From 2021 to 2023, convenience sampling was used to select 159 patients with rectal cancer who underwent sphincter-preserving surgery at Peking University Third Hospital as participants. The General Information Questionnaire, Food Frequency Questionnaire, and Defecation Questionnaire were used for the survey.Results:The incidence of defecation disorders in 159 patients with rectal cancer after sphincter-preserving surgery was 74.2% (118/159), and the types of defecation disorders with high to low incidence were "frequent defecation (96/159, 60.4%) " "constipation (37/159, 23.3%) " "diarrhea (33/159, 20.8%) " and "fecal incontinence" (24/159, 15.1%). Diets were clustered into 9 categories (vegetables and fruits, carbohydrate staple foods, red meat foods, gas producing foods, dairy products, white meat foods, dessert foods, high-fat foods, and spicy and stimulating foods). Binomial Logistic regression analysis showed that red meat foods and gas producing foods were the influencing factors of frequent defecation ( P<0.05), red meat foods was the influencing factor of diarrhea ( P<0.05), and carbohydrate staple foods was the influencing factor of fecal incontinence ( P<0.05) . Conclusions:The incidence of defecation disorders in patients with rectal cancer after sphincter-preserving surgery is relatively high, and the intake of red meat foods, gas producing foods, and carbohydrate staple foods should be appropriately controlled. Clinical medical and nursing staff should pay close attention to the diet of elderly patients.

The incidence of early-onset gastric cancer (EOGC) is consistently increasing, and its etiology is notably complex. This increase may be attributed to distinctive factors that differ from those associated with late-onset gastric cancer (LOGC), including genetic predispositions, dietary factors, gastric microbiota dysbiosis, and screening of high-risk cases. These factors collectively contribute to the onset of cancer. EOGC significantly differs from LOGC in terms of clinicopathological and molecular characteristics. Moreover, multiple differences in prognosis and clinical management also exist. This study aimed to systematically review the latest research advancements in the epidemiological characteristics, etiological factors, clinicopathological and molecular features, prognosis, and treatment modalities of EOGC.

Thyroid associated ophthalmopathy (TAO) is an organ-specific autoimmune disease. TAO is clinically classified into active and inactive stage, and the accurate judgment is the key point of treatment choice. Clinical activity score (CAS) is often used for the assessment of TAO activity, which is subjective to some extent. With the development of imaging techniques, ultrasonography, CT, MRI and radionuclide imaging have gradually been applied into the diagnosis and treatment of TAO. What′s more, the imaging is an important complement to CAS from the aspects of anatomical and functional metabolism, which can better assess the activity and the therapy response of TAO. The clinical value of medical imaging in activity and treatment efficacy evaluation of TAO is reviewed in this article.

Objective:To investigate the effects of improving the prenatal multidisciplinary consultation mode on the outcomes of fetuses with structural malformations.Methods:Clinical data of pregnant women attending the Prenatal Multidisciplinary Consultation Center, jointly established by the Obstetrics & Gynecology Hospital of Fudan University and the Children's Hospital of Fudan University from January 2004 to December 2019, were retrospectively collected and analyzed. In 2014, the center optimized the multidisciplinary consultation mode to achieve a more individualized approach to genetic testing based on more accurate imaging diagnosis and deeper cooperation between the obstetrics and pediatrics teams. Differences in the number of cases, structure of the diseases, genetic testing results, outcomes, and prognosis between the improved group (enrolled from January 2014 to December 2019) and the baseline group (enrolled from January 2004 to December 2013) were compared. The Chi-square test was used for statistical analysis. Results:(1) This study recruited 5 977 pregnant women, including 3 424 in the baseline group and 2 553 in the improved group. The main indications for consultation were fetal factors [97.2% (5 812/5 977)], among which congenital structural malformations accounted for 77.5% (4 503/5 812). There was a significant difference in the systematic distribution of congenital structural malformations between the two groups ( χ2=141.31, P<0.001). The proportion of malformations involving the central nervous, cardiovascular, and urinary systems ranked in the top three in both groups. (2) The percentage of women receiving genetic testing was higher in the improved group than in the baseline group [26.7% (682/2 553) vs. 15.9% (546/3 424), χ2=103.87, P<0.001] and the positive rate of genetic testing was also higher in the improved group [19.9% (136/682) vs. 9.9% (54/546). χ2=23.42, P<0.001]. (3) Among the 5 977 cases, 418 (7.0%) were lost to follow-up; 1 741 (29.1%) opted for pregnancy termination; 123 (2.2%) had intrauterine fetal death; and 3 695 (61.8%) were live births. The rate of pregnancy termination in the improved group was lower than that of the baseline group [27.7% (707/2 553) vs. 30.2% (1 034/3 424), χ2=4.45, P=0.035]. (4) In the 1 741 cases with pregnancy termination, fatal cardiovascular system malformations ( n=413, 23.7%), central nervous system malformations ( n=377, 21.7%), multiple malformations ( n=258, 14.8%), and chromosomal abnormalities ( n=162, 9.3%) were the main causes. The top five diseases leading to pregnancy termination were cleft lip and palate [59.0% (46/78)], meningocele (5/9), gastroschisis/omphalocele [49.3% (33/67)], diaphragmatic hernia [46.5% (33/71)], and skeletal malformations [40.9% (83/203)]. The rates of pregnancy termination due to gastroschisis/omphalocele, diaphragmatic hernia, and skeletal malformations in the improved group were all lower than those in the baseline group [57.4% (27/47) vs. 30.0% (6/20), χ2=4.23; 59.0% (23/39) vs. 31.3% (10/32), χ2=5.43; 51.8% (72/139) vs. 17.2% (11/64), χ2=21.72; all P<0.05]. (5) Among the 3 695 live births, 1 979 (53.6%) were delivered by cesarean section and 1 716 (46.4%) by vaginal delivery; 3 633 (98.3%) survived and 62 (1.7%) died in the neonatal period. The survival rate of newborns in the improved group was higher than that in the baseline group [98.8% (1 648/1 668) vs. 97.9% (1 985/2 027), χ2=4.23, P=0.040]. Among the 62 dead newborns, 51 (82.3%) had fatal structural or chromosomal abnormalities. (6) In the surviving neonates, 372 (10.2%) showed no abnormalities in a postnatal reexamination, and 468 (12.9%) received surgical treatment in the neonatal period. The other 2 793 cases received no treatment in the neonatal period but were followed up regularly. Conclusion:The optimized prenatal multidisciplinary consultation mode effectively reduces the rate of pregnancy termination due to non-fatal single structural malformations and increases the survival rate of newborns.

Purpose: The human epidermal growth factor receptor 2 (HER2) is an established therapeutic target for various kinds of solid tumors. HER2 amplification occurs in approximately 1% to 6% of colorectal cancer. In this study, we aimed to assess the efficacy and safety of trastuzumab in combination with chemotherapy in HER2-positive metastatic colorectal cancer (mCRC). Materials and Methods: An open-label, phase II trial (Clinicaltrials.gov: NCT03185988) was designed to evaluate the antitumor activity of trastuzumab and chemotherapy in HER2-positive digestive cancers excluding gastric cancer in 2017. Patients from this trial with HER2-positive, KRAS/BRAF wild-type, unresectable mCRC were analyzed in this manuscript. Eligible patients were treated with trastuzumab (8 mg/kg loading dose and then 6 mg/kg every 3 weeks) and irinotecan (120 mg/m2 days 1 and 8 every 3 weeks). The primary endpoint was the objective response rate. Results: Twenty-one HER2-positive mCRC patients were enrolled in this study. Seven patients (33.3%) achieved an objective res-ponse, and 11 patients (52.4%) had stable disease as their best response. The median progression-free survival (PFS) was 4.3 months (95% confidence interval, 2.7 to 5.9). Four of the 21 patients (19.0%) had grade 3 adverse events, including leukopenia, neutropenia, urinary tract infection, and diarrhea. No treatment-related death was reported. Exploratory analyses revealed that high tumor tissue HER2 copy number was associated with better therapeutic response and PFS. Alterations in the mitogen-activated protein kinase pathway, HER2 gene, phosphoinositide 3-kinase/AKT pathway, and cell cycle control genes were potential drivers of trastuzumab resistance in mCRC. Conclusion Trastuzumab combined with chemotherapy is a potentially effective and well-tolerated therapeutic regimen in mCRC with a high HER2 copy number.

Objective:To explore the clinical efficacy of adult donor dual kidney transplantation.Methods:Retrospective analysis of case data of 13 adult donor kidney dual kidney transplantation (DKT) performed in the The Second Xiangya Hospital of Central South University from September 2016 to December 2020. For 13 donors, the average age and BMI were (53.5±12.4)years and (24.3±2.8) kg/m 2, respectively. Their mean Serum creatinine (SCr) at admission and before procurement was (132.9±54.1)and (228.7±112.4)μmol/L, respectively. 3 of them had diabetes mellitus history, and 8 had hypertension history. 11 met the United Network for Organ Sharing (UNOS) DKT criteria and 6 met Remuzzi score DKT criteria. For 13 recipients, the average age and BMI were (39.3±8.9)years and (20.2±2.4)kg/m 2, respectively. All of them received ABO blood type-matched kidney transplants. 2 of them had their grafts transplanted in the bilateral iliac. In 12 cases, the grafts filled rapidly and urinated immediately when opening blood flow. In 1 case, the grafts were dark in color and vascular showed weak pulsation after opening blood flow. The time to recovery of perioperative graft function (from the day of surgery to the natural reduction of SCr to the normal range 44-133μmol/L), the occurrence of delayed graft function (DGF), acute rejection (AR), ureteral and surgical incision complications, as well as the recipients’ final follow-up SCr, eGFR, urinary protein, and grafts outcome were observed. Risk factors affecting outcomes were assessed by univariate logistic regression analysis. Results:The SCr dropped to the normal range at discharge in 10 recipients, and the average recovery time was (13.8±13.0) days. In other 3 cases SCr at discharge were 300.0, 149.0, 152.5μmol/L. 4 cases had DGF, 4 had AR, 1 experienced urinary fistula, and 1 experienced incisional dehiscence, which were treated with anti-rejection, J-tube implantation, continuous catheterization to maintain bladder void, secondary suturing, respectively. The follow-up time ranged from 4 to 54 months, with a median of 28(15.5, 31.0) months. At the final follow-up time, 10 cases had good graft function, 2 suffered impaired kidney function, and 1 experienced graft failure. The average SCr and eGFR except for graft failure patient were (144.2±101.3)μmol/L and (52.9±21.2)ml/min, respectively. 4 had positive urine protein. Univariate logistic regression analysis showed that donor age, BMI, history of diabetes mellitus and hypertension, and SCr were not significantly correlated with recipients’ DGF and graft impairment ( P>0.05), and due to the small sample size, multifactorial logistic regression analysis was not performed. Conclusion:The short to medium-term effects of adult donor DKT coule be safe and feasible.

Objective:To analyze the clinical characteristics of hospitalized premenopausal patients with hyperuricemia.Methods:The medical records of premenopausal women with hyperuricemia (serum uric acid ≥360 μmol/L during hospitalization) admitted in Peking Union Medical College Hospital from 2013 to 2018 were reviewed and the clinical data were analyzed.Results:A total of 2 099 patients were enrolled. Only 14.01% (294 cases) of the patients were concerned about hyperuricemia by physicians. Autoimmune diseases (32.11%, 674 cases), nephrotic disease (19.29%, 405 cases) and endocrine system diseases (9.72%, 204 cases) are the main reasons for hospitalization, while 6.34%(133 cases) of patients were in gestation. In terms of the etiology, renal diseases (49.35%, 1 035 cases), specific drug use (49.26%, 1 034 cases) were the main causes of secondary hyperuricemia in premenopausal women, followed by metabolic diseases (10.62%, 233 cases). There was no significant difference in serum uric acid level among premenopausal women of different ages ( H=4.47, P=0.107), but the etiology of hyperuricemia among patients of different ages had significant differences. The proportion of hyperuricemia in patients with cancer and metabolic syndrome,secondary to use of diuretics and anti-tuberculosis drugs had differences among different age groups ( χ2=90.96,52.89,19.26 and 6.41, P<0.05). Conclusion:Hyperuricemia is not uncommon in premenopausal women. There are many secondary factors leading to hyperuricemia in premenopausal women, among which drugs and renal lesions are the main causes. In addition, the secondary factors in women with hyperuricemia has differences among different age groups.
