Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.

Recent data suggest that vascular endothelial growth factor receptor inhibitor (VEGFRi) can enhance the anti-tumor activity of the anti-programmed cell death-1 (anti-PD-1) antibody in colorectal cancer (CRC) with microsatellite stability (MSS). However, the comparison between this combination and standard third-line VEGFRi treatment is not performed, and reliable biomarkers are still lacking. We retrospectively enrolled MSS CRC patients receiving anti-PD-1 antibody plus VEGFRi (combination group, n=54) or VEGFRi alone (VEGFRi group, n=32), and their efficacy and safety were evaluated. We additionally examined the immune characteristics of the MSS CRC tumor microenvironment (TME) through single-cell and spatial transcriptomic data, and an MSS CRC immune cell-related signature (MCICRS) that can be used to predict the clinical outcomes of MSS CRC patients receiving immunotherapy was developed and validated in our in-house cohort. Compared with VEGFRi alone, the combination of anti-PD-1 antibody and VEGFRi exhibited a prolonged survival benefit (median progression-free survival: 4.4 vs. 2.0 months, P=0.0024; median overall survival: 10.2 vs. 5.2 months, P=0.0038) and a similar adverse event incidence. Through single-cell and spatial transcriptomic analysis, we determined ten MSS CRC-enriched immune cell types and their spatial distribution, including naive CD4⁺ T, regulatory CD4⁺ T, CD4⁺ Th17, exhausted CD8⁺ T, cytotoxic CD8⁺ T, proliferated CD8⁺ T, natural killer (NK) cells, plasma, and classical and intermediate monocytes. Based on a systemic meta-analysis and ten machine learning algorithms, we obtained MCICRS, an independent risk factor for the prognosis of MSS CRC patients. Further analyses demonstrated that the low-MCICRS group presented a higher immune cell infiltration and immune-related pathway activation, and hence a significant relation with the superior efficacy of pan-cancer immunotherapy. More importantly, the predictive value of MCICRS in MSS CRC patients receiving immunotherapy was also validated with an in-house cohort. Anti-PD-1 antibody combined with VEGFRi presented an improved clinical benefit in MSS CRC with manageable toxicity. MCICRS could serve as a robust and promising tool to predict clinical outcomes for individual MSS CRC patients receiving immunotherapy.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes. If not intervened in time, NAFLD may develop into liver fibrosis or liver cancer, and ultimately threatening life. NAFLD has complicated etiology and pathogenesis, and there are no effective therapeutic means and specific drugs. Currently, insulin sensitizers, lipid-lowering agents and hepatoprotective agents are often used for clinical intervention, but these drugs have obvious side effects, and their effectiveness and safety need to be further confirmed. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis. Activated AMPK can enhance lipid degradation, alleviate insulin resistance (IR), suppress oxidative stress and inflammatory response, and regulate autophagy, thereby alleviating NAFLD. Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects. In this article, we reviewed the biologically active natural herbal medicines (such as natural herbal medicine formulas, extracts, polysaccharides, and monomers) that reported in recent years to treat NAFLD via regulating AMPK, which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Follicular lymphoma (FL) is highly heterogeneous with different histopathologic grades. Its biological characteristics and clinical management are different. This study retrospectively analyzed 18F-FDG PET-CT metabolic parameters, clinical features, and their relationship with prognosis in 161 FL patients with different histopathological grades (grade 1-2, grade 3A, grade 3B) at the Shanxi Cancer Hospital. There were 93 cases in the grade 1-2 group, 40 cases in the grade 3A group, and 28 cases in the grade 3B group. The expression of LDH, CD10, EZH2, c-Myc, and CD37 proteins was correlated with histological grade (grade 1-2, grade 3A, and grade 3B) (all P values<0.05) . The SUVmax, TLG, TBR, and TLR for the three groups were different (all P values<0.05) . The optimal thresholds of SUVmax, MTV, TLG, TBR, and TLR for predicting FL disease progression were 8.32, 201.31, 2 342.55, 6.56, and 3.52, respectively, and the rate of disease progression increased in patients with higher thresholds (all P value<0.05) . β 2-MG (>2.3 μg/L) , Follicular lymphoma international prognostic index-1 (FLIPI-1) score (3-5 points) , negative CD37 expression, positive c-Myc expression, and TLG (>2 342.55 g) were all independent risk factors for PFS in the FL patients ( HR=3.609, 2.509, 0.255, 3.506, 13.531, all P value<0.05) . 18F-FDG PET-CT is a powerful complement to FL histopathological grading and the combination of the two may better predict the prognosis of FL patients.

Objective To systematically evaluate the efficacy and safety of hydromorphone or morphine for cancer pain using intrathecal drug infusion system(IDDS).Methods Chinese and English literature databases,including CNKI,Wanfang,VIP,CBM,PubMed,Cochrane Library,and Ovid,were searched from inception to Aug.31,2023 to collect randomized controlled trials(RCTs)about intrathecal infusion of morphine or hydromorphone in treatment of cancer pain.Two reviewers independently screened literature and extracted data according to the inclusion and exclusion criteria,and evaluated the quality of RCTs using a Cochrane bias risk assessment tool.Then,meta-analysis was performed using RevMan 5.4.1 software.Results A total of 6 RCTs,involving 544 patients,were enrolled.Among them,there were 282 cases in the hydromorphone group and 262 cases in the morphine group.The meta-analysis results showed that there were no significant differences in pain score or number of breakthrough pain episodes between the 2 groups after treatment(all P＞0.05).Compared with the morphine group,the incidence rates of nausea and vomiting,constipation,and somnolence were significantly decreased in the hydromorphone group(P≤0.05),and the quality of life was significantly higher(P＜0.05).Conclusion The efficacy of hydromorphone administered by IDDS for cancer pain is comparable to morphine;hydromorphone has advantages in reducing adverse reactions and improving quality of life of patients.

Objective:To compare the prognostic values of different classification by using transpulmonary pressure gradient (TPG), diastolic pressure gradient (DPG) and pulmonary vascular resistance (PVR) in patients with pulmonary hypertension due to left heart disease (PH-LHD), and investigated hemodynamic and clinical factors associated with mortality in patients with PH-LHD.Methods:This was a single-center prospective cohort study. In-hospital patients diagnosed with PH-LHD via right heart catheterization at the Department of Cardiology, the First Affiliated Hospital of Nanjing Medical University, from September 2013 to December 2019 were enrolled. Patients were divided according to TPG (cutoff value 12 mmHg; 1 mmHg=0.133 kPa), DPG (cutoff value 7 mmHg), PVR (cutoff value 3 Wood Units), and the combination of TPG and PVR. Baseline characteristic was recorded. All patients were followed up until the occurrence of endpoint event, defined as all-cause death that occurred during the follow-up period, or until April 18, 2022. Receiver operating characteristic curves were used to compare the predictive value of 3 classification methods for all-cause death in PH-LHD patients. The optimal cutoff values were calculated using Jorden index. Survival analysis was performed using Kaplan-Meier analysis, and log-rank test was used to compare the predictive efficacy of classification methods based on optimal cutoff values or guidance-recommended thresholds for the survival of PH-LHD patients. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality.Results:A total of 243 patients were enrolled, aged (54.9±12.7) years old, including 169 (69.5%) males. During a median follow-up of 57 months, there were 101 (41.6%) deaths occurred. Grouping results were as follows: (1) TPG: TPG≤12 mmHg group 115 patients, TPG>12 mmHg group 128 patients; (2) DPG: DPG<7 mmHg group 193 patients, DPG≥7 mmHg group 50 patients; (3) PVR: PVR≤3 Wood Units group 108 patients, PVR>3 Wood Units group 135 patients; (4) TPG and PVR: TPG≤12 mmHg and PVR≤3 Wood Units group 89 patients, TPG>12 mmHg and PVR>3 Wood Units group 109 patients. PVR ( AUC=0. 698,95% CI:0.631-0.766) had better predictive value for all-cause mortality than TPG ( AUC=0.596, 95% CI: 0.523-0.669) and DPG ( AUC=0.526, 95% CI: 0.452-0.601) (all P<0.05). The optimal cutoff values for TPG, DPG, and PVR were13.9 mmHg, 2.8 mmHg, and 3.8 Wood Units, respectively. Kaplan-Meier analysis based on the optimal cutoff values or guidance-recommended thresholds showed that PVR and TPG were the predictors of survival ( P<0.05), while DPG did not showed significance ( P>0.05). Multivariate Cox regression analysis showed that age, PVR and log 2N-terminal pro-B-type natriuretic peptide were independent risk factors for all-cause mortality in PH-LHD patients (all P<0.05). Conclusion:Classification according to PVR was most valuable in predicting all-cause death in PH-LHD patients, while TPG showed moderate predictive ability and DPG had no predictive value.

Objective:To analyze and summarize the clinical, genotypic and pathological characteristics of children with PAX2 gene mutation in China, and to provide information for the monitoring, treatment and prognosis of the disease. Methods:It was a case series analysis study. The clinical data of children with PAX2 gene mutation in Pediatric Nephrology Department, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2022 were collected, and peripheral blood gene DNA was extracted and sequenced for whole exome sequencing. The clinical, pathological and genotypic characteristics of PAX2 gene variation of children in China were summarized by searching PubMed, Medline, China National Knowledge Infrastructure and Wanfang database and compared with the cases in this single center. Results:Among the 13 children with PAX2 gene mutation, there were 9 males and 4 females, 12 patients with abnormal urine tests, 7 patients with small kidney volume by imaging examination, and 5 patients with renal cysts. The clinical phenotypes were congenital renal and urinary tract malformations in 8 cases, renal coloboma syndrome in 1 case, and hematuria or proteinuria in 3 cases. Five patients underwent renal biopsies, showing focal segmental glomerulosclerosis and C3 glomerulopathy in 1 case, focal segmental glomerulosclerosis in 1 case, thin basement membrane lesion in 1 case, and IgA nephropathy in 2 cases. The genetic testing in 13 children showed 9 de novo mutations and 4 new mutations of c.321G>A, c.213-8C>G, c.63C>A and c.449C>T. There were 2 cases of 76dupG (p.V26Gfs*28) mutant. A total of 51 Chinese children with PAX2 gene mutation were found in the literature search. There were 32 males and 19 females, 8 cases with small kidney volume and 12 cases with renal cysts. The clinical phenotypes were congenital anomalies of kidney and urinary tract in 28 cases, renal coloboma syndrome in 17 cases, and hematuria or proteinuria in 6 cases. Seven patients underwent renal biopsies, including 2 cases with focal segmental glomerulosclerosis, 1 case with minimal lesion, 1 case with mesangial proliferative glomerulonephritis, 1 case with IgA nephropathy, 1 case with membranous nephropathy and a case with focal proliferative sclerosing purpura nephritis combined with glomerular hypertrophy. Thirty-four cases were de novo mutations, and 12 mutations were from the father or mother. The father or mother of 5 children had no clinical manifestations, with normal renal function. There were 11 cases of 76dupG (p.V26Gfs*28) mutant. Conclusions:The clinical phenotypes and genotypes of PAX2 gene variation in Chinese children are diverse. The most common clinical phenotype of PAX2 gene variation is congenital anomalies of kidney and urinary tract. c.76dupG (p.V26Gfs*28) is the most common of PAX2 gene variant.

Objective:To better evaluate the prevalence and epidemiological characteristics of metabolic-associated fatty liver disease (MAFLD) based on liver transient elastography.Methods:It was a cross-sectional study. A total of 6 961 patients without hepatitis, who underwent liver transient elastography examination at the Department of Hepatology, Zhongnan Hospital of Wuhan University from November, 2021 to April, 2022 were included. The patients were categorized into normal and mild, moderate, severe MAFLD groups according to FibroTouch controlled attenuation parameters (CAP). The CAP values among different body mass index (BMI) groups were compared using analysis of variance. The distribution characteristics and the incidence of MAFLD in different age, gender, body mass index(BMI), blood glucose and lipids groups using the chi-square test.Results:The total detection rate of MAFLD and severe MAFLD in the population with a BMI≥28.0 kg/m 2 was 99.6% and 71.8%, respectively. The detection rate of MAFLD in people with normal BMI was 28.4%. The detection rate of MAFLD in women of childbearing age or in the perimenopausal period were both significantly lower than that in men of the same age (40.3% vs 54.9%, χ 2=20.78, P<0.001; 43.1% vs 58.4%, χ 2=27.43, P<0.001), but there was no statistically significant difference in MAFLD detection rate between postmenopausal women and men of the same age. The detection rates of MAFLD in the group with abnormal blood glucose and lipids were both significantly higher than those in the group with normal blood glucose and lipids [69.7%(196/281) vs 35.2%(2 354/6 680), χ 2=138.36, P<0.001; 54.3%(1 696/3 124) vs 37.1%(1 420/3 837), χ 2=207.99, P<0.001]. Conclusion:Non-hepatitis patients had a higher prevalence of MAFLD. The BMI, gender, age, blood glucose, and lipids levels are all strongly associated with MAFLD.

Objective:To explore the impact of intradialytic hypotension (IDH) on brain component volume, as well as its relationship with depression and cognitive function changes in maintenance hemodialysis patients.Method:It was a cross-sectional observational study. Clinical data of 119 patients under maintenance hemodialysis in Peking Union Medical College Hospital from July 2013 to July 2014 were collected, retrospectively. Patients were divided into IDH group and non-IDH group. 3.0T Magnetic resonance imaging examination of the head for all patients was completed and the results of volume analysis of each component of the brain were extracted. Cognitive function was assessed by the Chinese version of the simplified mental state examination scale (C-MMSE) and the Chinese version of the Montreal cognitive assessment scale (C-MoCA). Depressive status was assessed by the Hamilton depression scale 17 (HAMD_17) and living ability was assessed by the Alzheimer's disease collaborative study-daily living ability assessment questionnaire. In addition, the Philadelphia word learning test was used to measure memory, the Boston naming test to measure language, the connection test A and B to measure executive ability, and the Stroup test C to measure attention. The differences in brain component volume, cognitive function, emotion, and life ability between two groups of patients were compared, and the correlation between IDH and brain component volume was explored by regression analysis.Result:A total of 119 patients were included in this study, of whom 22 (18.5%) had hypotension during dialysis. The volumes of amygdala, cuneiform lobe, and posterior cingulate gyrus in IDH group were significantly smaller than those in the non-hypotension group [ (1.6±0.2) mm 3vs. (1.7±0.2) mm 3, t=2.674, P=0.009; (6.9±0.8) mm 3vs. (7.4±1.0) mm 3, t=2.187, P=0.031; (6.9±0.8) mm 3vs. (7.4±0.9) mm 3, t=2.252, P=0.024]. The differences of gray matter, white matter volume between the two groups showed a similar trend but did not reach statistical significance. And lacunar infarction and cerebral microbleeds were more common in IDH group. The daily living ability scores of the two groups were similar (65.51±11.52 vs. 65.71±11.53, Z=-0.456, P=0.648). The proportion of patients with cognitive abnormalities was higher in the IDH group, without statistical significance. The proportion of depression was similar. Univariate linear regression analysis showed that IDH was significantly negatively correlated with the volume of amygdala, cuneiform cortex, and posterior cingulate gyrus, which control emotions in the brain ( B=-0.117, 95% CI -0.203--0.030, P=0.009; B=-0.484, 95% CI -0.923--0.046, P=0.031; B=-0.485, 95% CI -0.911--0.058, P=0.026). After multivariate adjustment, decreased amygdala volume was still correlated with IDH ( B=-0.111, 95% CI -0.198--0.025, P=0.026). Conclusion:Recurrent IDH may lead to atrophy of various brain components, which may be one of the reasons for cognitive and emotional changes in maintenance hemodialysis patients.

Objective:To determine a relationship between ultrasound shear wave elastography (SWE) and pathological lessions of renal tissues in children with chronic kidney disease (CKD).Methods:It was a cross-sectional observational study, involving children admitted to the Department of Pediatrics of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2021 with definite pathological diagnosis through kidney biopsy. The SWE was used to determine the Young's modulus (elastic modulus) of the cortex and medulla of the upper, middle, and lower poles of the kidney. The renal histopathology was classified or graded. The statistical method was used to analyze the relationship between Young's modulus of the inferior polar cortex (YM cor) and medulla (YM med) of the right kidney and renal pathology. Results:The study included 110 children with definite pathological diagnosis through renal biopsy, aged (10.1±3.4) years old (2-17 years old), with 55 males (50.0%). The body mass index was (20.6±2.4) kg/m 2, and mean arterial pressure was (95±24) mmHg. There were 94 patients (85.4%) with CKD stage 1, 8 patients (7.3%) with CKD stage 2, and 8 patients (7.3%) with CKD stage 3. There was no significant difference of YM cor and YM med in the upper and middle poles of the right kidneys, and YM med in the lower poles of right kidneys in CKD patients with different stages (all P>0.05). Both YM cor [(15.75±3.36) kPa] and YM med [(13.50±2.43) kPa] of CKD stage 3 patients were significantly higher than those of CKD stage 1 patients [(12.94±2.45) kPa, (11.88±2.23) kPa](both P<0.05). There was no significant difference of YM cor and YM med in the lower poles of right kidneys between stage 1 and stage 2 CKD patients (both P>0.05). YM cor[(17.93±3.23) kPa] and YM med [(15.50±1.48) kPa] in patients with crescentic glomerulonephritis were higher than those in patients with focal segmental glomerulosclerosis [(12.71±2.42) kPa, (11.57±2.63) kPa] and mesangial proliferative glomerulonephritis [(12.73±2.04) kPa, (11.48±2.10) kPa](all P<0.05). There was no significant difference of YM cor and YM med between focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis (both P>0.05). YM cor [(16.30±2.63) kPa] and YM med [(15.54±1.59) kPa] of Lee's Ⅳ grade of IgA nephropathy were higher than those of Lee's Ⅲ grade [(13.32±2.70) kPa, (12.57±2.50) kPa](both P<0.05), while the International Study of Kidney Disease in Children grade of purpura nephritis had no significant correlation with YM cor and YM med (both P>0.05). YM cor [(15.41±2.37) kPa] and YM med [(13.82±2.59) kPa] of interstitial fibrosis/tubular atrophy (T1/T2) group of IgA nephropathy mixed with purpura nephritis were significantly higher than those of T0 group's [(12.99±2.40) kPa, (11.79±2.05) kPa] (both P<0.05). Moreover, crescent formation (C1) group had a higher YM cor [(14.21±2.77) kPa] and YM med [(12.80±2.47) kPa] than those in C0 group [(12.73±2.15) kPa, (11.59±1.97) kPa] (both P<0.05), while YM cor and YM med were unrelated to the mesangial hypercellularity (M), endocapillary cellularity (E), segmental sclerosis or adhesion (S) indicators (all P>0.05). In lupus nephritis patients, YM cor ( r=0.744, P=0.035) and YM med ( r=0.728, P=0.009) were favorably linked with the chronic index, but not with the activity index (both P>0.05). Conclusions:Renal interstitial fibrosis/tubular atrophy and crescentic development are connected with YM cor and YM med at the lower pole of the kidney as measured by SWE. SWE can be used to assess the chronic renal lesions in children with CKD in the early and middle stages. It may develop into a new noninvasive way to assess renal pathology.
