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.

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.

Objective:To explore the intervention effect of health nutrition model based on digital management on patients with gestational diabetes mellitus, and to provide reference for blood sugar control and pregnancy outcome improvement of gestational diabetes mellitus.Methods:Using a randomized controlled study method, totally 80 cases of gestational diabetes mellitus admitted to Langfang People's Hospital from October 2021 to March 2023 were prospectively selected and randomly divided into control group and experimental group according to the random number table method, with 40 cases in each group. The control group was given routine management, and the experimental group was combined with the health nutrition model based on digital management on this basis. Both groups began to intervene after the diagnosis of gestational diabetes mellitus, and the intervention lasted until one week before the patient's expected delivery. Follow-up to delivery. The delivery mode, weight gain during pregnancy, insulin use during pregnancy, pregnancy outcome and neonatal outcome of the two groups were statistically analyzed. The blood glucose level of the two groups before and after intervention were compared.Results:The age of the control group was 20-31 (26.25 ± 1.98) years old, while the age of the experimental group was 20-33 (25.93 ± 2.11) years old. The cesarean section rate in the experimental group was 32.50% (13/40), which was lower than that in the control group (57.50%, 23/40) ( χ2=5.05, P<0.05). The weight gain during pregnancy in the experimental group was (6.03 ± 0.89) kg, which was lower than (7.93 ± 1.36) kg in the control group ( t=7.39, P<0.05). After intervention, the levels of serum glycosylated hemoglobin, fasting blood glucose and 2 h postprandial blood glucose in the two groups were lower than those before intervention, and those in the experimental group were (5.19 ± 0.54) %, (4.98 ± 0.49) mmol/L, (6.04 ± 1.15) mmol/L, which were lower than (5.67 ± 0.75) %, (5.37 ± 0.54) mmol/L, (7.16 ± 1.36) mmol/L in the control group ( t=3.28, 3.42, 3.96, all P<0.05). The proportion of macrosomia in the experimental group was 2.50% (1/40), which was lower than 20.00% (8/40) in the control group ( χ2=4.51, P<0.05). The experimental group had no abnormal pregnancy outcome and neonatal outcome respectively as 92.50% (37/40) and 92.50% (37/40), which were 70.00% (28/40) and 57.50% (23/40) in the control group, their difference was statistically significant ( χ2=6.65, 13.07, both P<0.05). Conclusions:The application of health nutrition model based on digital management to intervene in patients with gestational diabetes could effectively improve their blood glucose control effect, improve pregnancy outcome and neonatal outcome, and hada good intervention effect.

ObjectiveTo observe the clinical efficacy and possible mechanisms of Xianglian Huazhuo Granules （香连化浊颗粒， XHG） in the treatment of chronic atrophic gastritis with intestinal metaplasia. MethodsA total of 140 patients with chronic atrophic gastritis and intestinal metaplasia were randomly divided into a treatment group and a control group， with 70 cases in each group. The treatment group received 12.5 g of XHG orally， twice daily. The control group received 12.5 g of placebo orally， twice daily. Both groups were treated for 6 months. The traditional Chinese medicine （TCM） symptom scores， pathological types， serum tumor markers of the digestive system， and serum bile acids （TBA）， interleukin-23 （IL-23）， and Dickkopf-related protein 1 （DKK-1） levels were observed before and after treatment. Safety indicators and adverse events were recorded. After treatment， TCM syndrome efficacy and pathological types were evaluated， and patients were followed up for 18 months with gastric endoscopy and pathological results， which were compared with the results after treatment finished. ResultsTwo patients dropped out in the control group， and a total of 168 cases were included in the final analysis， 70 in the treatment group and 68 in the control group. The treatment group showed a significant reduction in TCM symptom scores， serum TBA， IL-23， and DKK-1 levels， and a significant increase in alpha-fetoprotein （AFP）， carbohydrate antigen 125 （CA125）， carbohydrate antigen 199 （CA199） levels； in the control group， carcinoembryonic antigen （CEA）， CA125， CA199 levels significantly increased （P＜0.05 or P＜0.01）； and carbohydrate antigen 242 （CA242） level in both the treatment group and the control group decreased significantly （P＜0.01）. The treatment group had lower TCM symptom scores and lower levels of serum TBA， IL-23， and DKK-1 compared to the control group （P＜0.05）. The effective rate for TCM syndrome efficacy in the treatment group was 80.00% （56/70）， significantly higher than the 20.59% （14/68） in the control group （P < 0.05）. The effective rate for pathological classification in the treatment group was 72.73% （8/11） for mixed intestinal metaplasia， significantly better than 46.15% （6/13） in the control group （P＜0.05）. No adverse events were reported in either group. Among 40 patients who had a follow-up endoscopy after one year， 21 were from the treatment group， of whom 11 showed reduced intestinal metaplasia， 9 showed no significant changes， and 1 had worsened； while 19 patients in the control group had 4 with reduced intestinal metaplasia， 13 with no significant changes， and 2 with worsened conditions. No cancer was detected in either group. The treatment group showed significantly better improvement in intestinal metaplasia on follow-up gastric endoscopy pathology than the control group （P＜0.05）. ConclusionXHG can significantly improve the clinical symptoms in patients with chronic atrophic gastritis and intestinal metaplasia and reduce the degree of mixed intestinal metaplasia. The mechanism may involve lowering serum TBA， DKK-1， and IL-23 levles， thus delaying the progression from inflammation to cancer.

Objective To analyze the practical value of spiral CT three-dimensional reconstruction techniquein evaluating triplane fractures of the distal tibia.Methods A retrospective analysis was conducted on183 patients with triplane fractures of the distal tibia admitted to Sichuan Orthopedic Hospital from January 2021 to March 2023.All patients underwent both X-ray and spiral CT examinations.Taking surgical reduction results as the gold standard for diagnosis,the diagnostic accuracies of X-ray examination and spiral CT three-dimensional reconstruction technique for triplane fractures of the distal tibia were analyzed.Results Fracture classification according to the number of fracture fragments showed that among the 183 patients with triplane fractures of the distal tibial,there were 44 cases of four-part fractures,62 cases of three-part fractures,and 77 cases of two-part fractures.The classification by the location of epiphyseal injury in the distal tibia showed 175 cases of lateral type and 8 cases of medial type.According to whether the fracture line involved the articular surface,they were categorized into 94 cases of type I,60 cases of type II,and 29 cases of type III.For the classification of the number of fracture fragments,X-ray misdiagnosed 9 cases of four-part fractures as three-part or two-part fractures,and 21 cases of three-part fractures as two-part fractures,resulting in a diagnostic accuracy of 83.60%.For theclassification of fracture line and articular surface position,X-ray led to misdiagnosis or inaccurate diagnosis in 39 cases,with a diagnostic accuracy of 78.69%.When spiral CT three-dimensional reconstruction technique was used to classify the number of fracture fragments,only 1 case of four-part fracture was misdiagnosed as three-part fracture,and 2 cases of three-part fractures were misdiagnosed as four-part fractures or two-part fractures,yielding a diagnostic accuracy of 98.36%.For the diagnosis of the positional relationship of the fracture line to the articular surface,spiral CT three-dimensional reconstruction technique had 8 misdiagnoses,with a corresponding diagnostic accuracy of 95.63%.Conclusion Spiral CT three-dimensional reconstruction technique can stereoscopically display the spatial information of the triplane fractures of the distal tibia,such as the location,shape,type,and articular surface,exhibiting high accuracy for classification diagnosis and significant application value in the reduction and treatment of triplane fractures of the distal tibia.

BACKGROUND:Mongolian medicine Echinops sphaerocephalus L.is a commonly used medicine for bone injury in Mongolian medicine.It is effective for tendon injury,fracture,bone nonunion,bone fever,tingling,sore and other diseases.Our previous studies have confirmed that Mongolian medicine Echinops sphaerocephalus L.can promote the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells,but its effect on angiogenesis in the process of bone defect repair is unknown.OBJECTIVE:To investigate the effect of Echinops sphaerocephalus L.on in vitro angiogenesis in human umbilical vein vascular endothelial cells and to explore the angiogenesis-promoting active ingredients and their mechanisms of action of Echinops sphaerocephalus L.using network pharmacology technology.METHODS:The ethanol extract of Echinops sphaerocephalus L.was prepared and preserved by freeze-drying.The proliferation,migration,chemotaxis and angiogenesis of human umbilical vein endothelial cells were observed after treatment with different concentrations(1 000,100,and 10 μg/mL)of Echinops sphaerocephalus L.The active components and possible signaling pathways that promoted angiogenesis were enriched and analyzed by network pharmacology.RESULTS AND CONCLUSION:(1)The effect of Echinops sphaerocephalus L.on angiogenesis was regulated by its mass concentration:at low mass concentration(10 μg/mL),Echinops sphaerocephalus L.could promote the proliferation,migration,chemotaxis and angiogenesis of human umbilical vein vascular endothelial cells;on the contrary,Echinops sphaerocephalus L.inhibited the proliferation,migration,and chemotaxis of human umbilical vein endothelial cells at high mass concentration(1 000 μg/mL).However,the inhibitory effect of Echinops sphaerocephalus L.on angiogenesis was not significant at high mass concentration due to the limitation of experimental time.10 μg/mL Echinops sphaerocephalus L.could up-regulate the mRNA expression of angiogenesis-associated factors,including kinase insert domain receptor,vascular endothelial growth factor A,and hypoxia-inducible factor α,and thereby influenced angiogenesis during bone repair.(2)Network pharmacological analyses indicated that Echinops sphaerocephalus L.may bind to eight core targets(TGFB1,TNF,IL-6,STAT3,CTNNB1,IL-1B,AKT1,and HIF-1A)through four core active components(apigenin,caffeic acid,quercetin,and chlorogenic acid)to exert an effect on angiogenesis,atherosclerosis,multiple viral infections,and tumor angiogenesis-related signaling pathways.
