Traditional Chinese medicine （TCM）， through its multi-target and systematic regulatory effects， has demonstrated unique advantages in the treatment of gastric precancerous lesions （GPL）. At present， TCM theoretical research on GPL is mainly reflected in three aspects， the integration of macroscopic syndrome differentiation， the inflammation-carcinoma transformation mechanism， as well as the systematization and scientization of theoretical inheritance from famous TCM practitioners. High-quality evidence-based research findings serve as the foundation for clinical practice guidelines on GPL， and TCM has gained international academic recognition in the field of GPL prevention and treatment. Research on TCM mechanisms has yielded a series of important outcomes in the aspects of signaling pathways， gene expression regulation， cellular epigenetics， histone modification， and intestinal microecology. It is proposed that future research on GPL should focus on four key directions， establishing multi-omics data， exploring targeted intervention strategies on key regulatory nodes， advancing the standardization process of integrated traditional Chinese and western medicine prevention and treatment technologies， and constructing stratified screening and intervention platforms. The in-depth integration of TCM microcosmic mechanism of action with its macroscopic syndrome differentiation and treatment system， coupled with interdisciplinary research， will provide valuable references for the clinical treatment and scientific research of GPL.

ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis （CAG） with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching， patients were divided into a training set （namely dev） and a validation set （namely vad） in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator （namely Lasso） regression algorithms. Subsequently， a model， named model 1se， was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods， including the receiver operating characteristic （ROC） curve， Hosmer-Lemeshow test （H-L）， calibration plot， and decision curve analysis （DCA）. ResultsAge， body mass index （BMI）， family history of cancer， job and life satisfaction， yellow and greasy fur with slippery pulse， and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration， which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

Recently， Gastroenterological Society of Australia convened a multidisciplinary group and applied a modified Delphi process to develop the first Australian consensus statement on the application of transjugular intrahepatic portosystemic shunt （TIPS） in portal hypertension. To address the current issues of insufficient application and a lack of standardized protocols for TIPS in Australia， this consensus provides evidence-based recommendations across the key domains of preoperative preparation and assessment for TIPS， surgical standards， postoperative care and follow-up， and specific clinical indications， in order to provide standardized guidance for the comprehensive management of TIPS in liver disease patients with portal hypertension. This article gives an excerpt of the key statements in the consensus.

ObjectiveTo investigate the patterns of chronic disease comorbidity among permanent elderly residents in Xuhui District of Shanghai, and to analyze the impact of different comorbidity patterns on the elderly’s ability to perform activities of daily living. MethodsBased on data from the 2015 and 2021 Surveys on Health Status and Health Service Utilization among Permanent Residents in Xuhui District of Shanghai, the study included permanent residents who fully participated in both surveys, were aged 60 years or older at the 2015 survey, self-reported having a chronic disease, and reported no significant changes in their chronic disease status between the two surveys. A prospective cohort study design was adopted, using the 2015 data as the baseline and the 2021 survey data as follow-up data. Physical examinations and questionnaire surveys were conducted by the Shanghai Xuhui District Center for Disease Control and Prevention in the subdistricts and towns within the jurisdiction from April to July in both 2015 and 2021. Latent class analysis (LCA) was used to classify comorbidity patterns across 11 types of chronic diseases. The smaller the values of the Akaike information criterion (AIC), the Bayesian information criterion (BIC), and the sample-corrected Bayesian information criterion (aBIC), the better the model fits. The Barthel index (BI) and the Lawton and Brody Instrumental Activities of Daily Living Scale (LB-IADL) were used to assess the participants’ activities of daily living (ADL) and instrumental activities of daily living (IADL). Multiple linear regression and multivariate logistic regression models were used to analyze the association between different comorbidity patterns and ADL and IADL. ResultsA total of 1 608 study participants were enrolled. Among them, 671 (41.73%) self-reported having no chronic diseases. The prevalence of 11 types of chronic diseases was as follows: hypertension in 743 participants (46.21%), heart disease in 148 participants (9.20%), cerebrovascular disease in 37 participants (2.30%), diabetes or abnormal blood glucose in 310 participants (19.28%), other endocrine system diseases (non-diabetic) in 39 participants (2.43%), malignant tumors in 37 participants (2.30%), chronic lung disease in 16 participants (1.00%), gout in 8 participants (0.50%), musculoskeletal disorders in 34 participants (2.11%), gastric or digestive system diseases in 27 participants (1.68%), and dyslipidemia in 15 participants (0.93%). LCA was used to classify comorbidity patterns of chronic diseases among older adults into 1 to 9 latent category combinations. Model 5 (i.e., 5 latent categories) had the lowest BIC (7 112.69) and aBIC (6 909.38), with a relatively low AIC (6 768.20), indicating the best model fit; thus, five latent categories represented the optimal combination in this study. The five latent categories (and their respective proportions of study participants) were the healthy control group (41.73%), the hypertension group (31.28%), the diabetes-hypertension group (19.28%), the severe illness group (5.29%), and the other metabolic diseases group (2.43%). According to multiple linear regression analyses, compared with the healthy control group, the diabetes-hypertension group had significantly lower BI-20 scores (b=-0.952, 95%CI: -1.317‒ -0.587, P<0.001) and lower IADL scores (b=-0.744, 95%CI: -0.999‒ -0.489, P<0.001); the severe illness group (b=-0.644, 95%CI: -1.072‒ -0.217, P=0.003) and the hypertension group (b=-0.344, 95%CI: -0.562‒ -0.125, P=0.002) had lower IADL scores. According to multivariate logistic regression analyses, compared with the healthy control group, older adults in the diabetes-hypertension group had a higher risk of disability (OR=2.835, 95%CI: 1.392‒5.774), impaired ADL function (OR=2.470, 95%CI: 1.637‒3.726), and impaired IADL function (OR=1.739, 95%CI: 1.264‒2.392); older adults in the severe illness group had a higher risk of impaired ADL function (OR=2.206, 95%CI: 1.171‒4.155). ConclusionAmong the elderly participating in the Survey on Health Status and Health Service Utilization of Permanent Residents in Xuhui District of Shanghai, diabetes-hypertension is one of the key chronic disease comorbidity combinations and has adverse effects on both ADL and IADL. Community health management should prioritize the elderly with diabetes-hypertension comorbidity, and strengthen early screening and comprehensive interventions to slow the decline in ADL and IADL.

ObjectiveTo investigate the mechanism by which Xianglian Huazhuo prescription （XLHZ） ameliorates chronic atrophic gastritis （CAG） through regulating glycolysis via the microRNA-34b-5p （miR-34b-5p）/6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 1 （PFKFB1） signaling pathway. MethodsBioinformatic screening was performed to identify the target genes of miR-34b-5p. In the animal experiments， a mouse model of CAG was established through a combination of N-methyl-N′-nitro-N-nitrosoguanidine （MNNG）， ranitidine， and irregular feeding. The mice were randomized into the following groups： normal， model， Morodan group （2 g·kg^-1）， and high-， medium-， and low-dose XLHZ groups（7.2，3.8，1.9 g·kg^-1）. In the cell experiments， GES-1 cells were treated with MNNG for the modeling of CAG and grouped as follows： GES-1， MNNG+GES-1， MNNG+GES-1+XLHZ（10%）， MNNG+GES-1+miR-34b-5p mimics， MNNG+GES-1+miR-34b-5p inhibitor， MNNG+GES-1+PFKFB1 inhibitor， and MNNG+GES-1+PFKFB1 mimics+XLHZ（10%）. The general conditions of mice were observed. Real-time PCR was adopted to measure the expression levels of miRNA-34b-5p and PFKFB1 mRNA in the gastric mucosa of mice in each group. Dual luciferase reporter gene was used to verify the targeting interaction between miR-34b-5p and PFKFB1 in GES-1 cells exposed to MNNG. The cell-counting kit-8 （CCK-8） was used to screen the drug-containing serum concentration. Real-time PCR was employed to verify the transfection efficiency. Fluorescent probes were used to detect the expression and nuclear translocation of hypoxia-inducible factor-1α （HIF-1α） in each group of cells. The protein levels of HIF-1α， hexokinase 2 （HK2）， PFKFB1， phosphofructokinase 1 （PFK1）， and lactate dehydrogenase （LDHA） in the gastric mucosa of mice were determined by Western blot. The levels of glucose consumption and lactate in the serum and cells were measured by biochemical methods. Enzyme-linked immunosorbent assay （ELISA） was adopted to measure the content of adenosine triphosphate （ATP） in the gastric mucosa tissue and cells. ResultsThe animal experiments showed that compared with the normal group， the model group exhibited symptoms including mental fatigue， lethargy， sparse and dull fur， a tendency to curl up， sluggish responses， reduced food and water intake， and slow body weight gain. In addition， the model group showed decreased expression of miRNA-34b-5p （P<0.01）， increased mRNA level of PFKFB1 （P<0.01）， upregulated protein levels of HIF-1α， HK2， PFKFB1， PFK1， and LDHA （P<0.01）， and increased glucose consumption， lactate content， and ATP content （P<0.01）. Compared with the model group， the XLHZ group and Morodan group showed improved mental state， gradually improved fur， increased activity， food and water intake， and body weight. HE showed that each treatment group exhibited well arranged and increased gastric mucosal glands， reduced inflammatory cells， and recovered gastric pits. Transmission electron microscopy showed that the size of mitochondria in each treatment group returned to normal， with no obvious irregular shape， complete and clear cristae， and uniform matrix. Furthermore， each treatment group showed increased expression of miRNA-34b-5p （P<0.05）， reduced mRNA level of PFKFB1 （P<0.05）， downregulated protein levels of HIF-1α， HK2， PFKFB1， PFK1， and LDHA （P<0.05）， and decreased glucose consumption， lactic acid， and ATP （P<0.05）. The cell experiments showed that the expression and nuclear translocation of HIF-1α were reduced in all groups after treatment （P<0.05）. The cell transfection efficiency was satisfactory （P<0.05）. miR-34b-5p exhibited an effect comparable to that of XLHZ， effectively inhibiting glycolysis， whereas PFKFB1 promoted glycolysis and reversed the protective effect of XLHZ in CAG mice （P<0.05）. ConclusionXLHZ could regulate the miR-34b-5p/PFKFB1 axis to inhibit glycolysis， thereby ameliorating MNNG-induced gastric mucosal atrophy.

Objective To study the death status of pancreatic cancer among residents in Xuhui district, Shanghai, from 1992 to 2021, and analyze its trends of change, so as to provide evidence for the prevention and treatment of pancreatic cancer. Methods Based on the database of Shanghai death registration system from 1992 to 2021, the crude mortality rate, standardized mortality rate, age-specific mortality rate and other indicators of pancreatic cancer among registered residents in Xuhui district were calculated. The Joinpoint software was used to analyze the trends of average annual percent change (AAPC) of pancreatic cancer mortality rate, and the age-period-cohort model was used to analyze the age effect, period effect and birth cohort effect pairs significant changes in pancreatic cancer mortality. Results In 2021, the mortality rate of pancreatic cancer in Xuhui district, Shanghai, ranked fourth among malignant tumors, and the winning rate and world standard rate of the whole population, males and females were 8.34/100 000 (8.81/100 000, 7.98/100 000) and 7.28/100 000 (7.69/100 000, 6.96/100 000), respectively, with males higher than females. AAPC of crude mortality rate and the standardized (6) mortality rate were higher in males than that in females. The age-specific mortality rate increased with the increase of age, and the highest mortality rate was found in 60-84 years old group. The age-period-cohort model showed that from 1992 to 2021, the annual net shift of pancreatic cancer mortality among the whole population, male and female residents in Xuhui district, Shanghai, was 1.22%, 1.58%, 1.15% (P=0.20, 0.19, 0.45) respectively, and the time trend was not significant. From the perspective of age effect, the risk of death from pancreatic cancer in the whole population and with age deviation in males had an obvious trend with increasing age (P<0.05), while the age effect in females had no obvious trend. From the perspective of period effect, no period deviation was significant in the whole population, males and females (P>0.05). In terms of cohort effects, there were significant differences in the whole population and the male cohort deviations(P<0.05). No significant cohort effect was observed in the female population. Conclusions The mortality rate of pancreatic cancer among registered residents in Xuhui district, Shanghai from 1992 to 2021, was on the rise, especially in the 60-84 years old group and male. The prevention and control of pancreatic cancer needs to develop effective epidemic prevention measures for corresponding populations.

Objective:To investigate the clinical characteristics and prognosis of T-lymphoblastic lymphoma (T-LBL).Methods:A retrospective case series study was conducted. Clinical data of patients diagnosed with T-LBL at the Affiliated Hospital of Jining Medical University from January 2013 to March 2023 were retrospectively analyzed, and their clinical characteristics and prognosis were statistically analyzed.Results:A total of 22 T-LBL patients were included. Among them, there were 19 males (86.4%) and 3 females (13.6%), and the median age at onset was 19.5 (15, 28) years old. Based on Ann Arbor staging, 3 cases (13.6%) were classified as stage Ⅰ-Ⅱ, while 19 cases (86.4%) were stage Ⅲ-Ⅳ; 10 cases (45.5%) presented with B symptoms, 12 cases (54.5%) without B symptoms; 16 cases (72.7%) showed elevated lactic dehydrogenase (LDH) level. At onset, 7 patients (31.8%) had mediastinal masses, 3 patients (13.6%) had central nervous system involvement, and 17 patients (77.3%) had bone marrow involvement. The overall response rate (ORR) and complete remission rate among the 22 patients were 81.82% (18/22) and 31.82% (7/22), respectively. The ORR was 84.21% (16/19) in 19 patients treated with ALL-like regimens. Among 3 patients treated with NHL-like regimens, 1 case achieved complete remission and 1 case achieved partial remission. Seven patients received allogeneic hematopoietic stem cell transplantation, with a median overall survival (OS) time of 22 months; the median OS time of patients without allogeneic hematopoietic stem cell transplantation was 14 months. The 3-year OS rates in the allogeneic hematopoietic stem cell transplantation group and group without allogeneic hematopoietic stem cell transplantation were 64.30% and 16.00%, and the difference in OS between the two groups was statistically significant ( P = 0.043). Two patients with disease progression prior to transplantation died of multidrug-resistant bacterial infections after transplantation. Conclusions:T-LBL is rare, and it is a highly aggressive tumor that predominantly occurs in adolescent males. Allogeneic hematopoietic stem cell transplantation can prolong OS, reduce relapse and improve the prognosis of patients.

Alzheimer's disease(AD)is a chronic neurodegenerative disease that severely affects the quality of life of the elderly.Its main pathological features include the deposition of β-amyloid protein to form senile plaques,neurofibrillary tangles caused by abnormal phosphorylation of tau pro-tein,as well as extensive neuronal loss and synaptic dysfunction.In recent years,mesenchymal stem cells(MSCs)and their exosomes(MSC-Exos)have attracted extensive attention due to their poten-tial in the treatment of neurodegenerative diseases.MSCs possess multidirectional differentiation po-tential,immunomodulatory capacity,and significant neuroprotective and repair effects.As an impor-tant signaling mediator of MSCs,MSC-Exos are a type of nanoscale double-layer membrane-structured vesicles secreted by MSCs,capable of carrying and delivering various bioactive substances.MSCs and their derived MSC-Exos have demonstrated good safety and efficacy in the treatment of AD.This arti-cle systematically reviewed the basic and translational research progress on MSCs and MSC-Exos in the treatment of AD in recent years.
