Objective:To investigate the application value of a multi-dimensional digital moni-toring platform for perioperative period in gastric cancer patients.Methods:The retrospective cohort study was conducted. The clinical data of 50 patients who underwent laparoscopic radical gastrec-tomy in The Affiliated Hospital of Nanjing University of Chinese Medicine from July 2022 to January 2024 were collected. There were 35 males and 15 females, aged (64±12)years. All patients followed the concept of enhanced recovery after surgery, and the multi-dimensional digital monitoring platform based on wearable monitoring equipment was used to implement perioperative management measures. Observation indicators: (1) results of heart rate variability (HRV) monitoring; (2) results of blood glucose and blood oxygen monitoring; (3) results of exercise and sleep monitoring; (4) results of body composition monitoring. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(IQR). Repeated measurement data were analyzed using the repeated ANOVA. Measurement data with skewed distri-bution were transformed to normal distribution by SPSS transformation function before testing. For comparison between pre- and postoperation, paired sample t test was used for measurement data with normal distribution, and nonparametric Wilcoxon signed rank sum test was used for measure-ment data with skewed distribution. Results:(1) Results of HRV monitoring. From preoperation to the third day after surgery, the standard deviation normal to normal heart beat of 50 patients was changed from(103±26)ms to(101±36)ms, the mean of the standard deviations of normal to normal heart beat calculated per 5 min segment was changed from (45±16)ms to(33±12)ms, the number of pairs of adjacent NN intervals differing by more than 50 ms in the entire recording was changed from 6.02%(4.96%) to 5.79%(4.20%), the low frequency power was changed from 376.78(468.96)ms 2 to 742.79(525.20)ms 2, the high frequency power was changed from 273.61(273.58)ms 2 to 397.48(164.87)ms 2, the ratio of low frequency power to high frequency power was changed from 1.6±0.5 to 1.6±0.6, showing significant differences in above indicators before and after operation ( F=34.43, 26.15, 24.58, 5.51, 6.11, 6.02, P<0.05). (2) Results of blood glucose and blood oxygen monitoring. From preoperation to the third day after surgery, the blood glucose of 50 patients was changed from 6.75(2.05)mmol/L to 6.90(2.63)mmol/L, showng a significant difference before and after operation ( F=45.84, P<0.05). The blood oxygen was changed from 97.00%(5.00%) to 97.50%(3.00%), showing no significant difference before and after operation ( F=2.25, P>0.05). (3) Results of exercise and sleep monitoring. From preoperation to the third day after surgery, the number of steps fo 50 pati-ents was changed from 3 043(1 224) to 1 473(767), sleep duration was changed from(8.2±1.1)hours to(7.3±0.8)hours, sleep score was changed from 80±10 to 78±5,showing significant differences in above indicators before and after operation ( F=716.46, 29.02, 47.32, P<0.05).(4) Results of body composition monitoring. The body weight of 50 patients was changed from (63±8)kg to(61±8)kg before and after operation, body fat rate was changed from 24%±8% to 22%±9%, muscle mass was changed from 43 (12)kg to 41(17)kg, body mass index was changed from (23.0±2.6)kg/m 2 to(22.1±2.5)kg/m 2, showing significant differences in above indicators before and after operation ( t=8.19, 3.00, Z=-2.78, t=7.34, P<0.05), while there was no significant difference in basal metabolic indicators from (1 390±134)kcal to (1 379±139)kcal before and after operation ( t=1.02, P>0.05).

Background Chronic intermittent hypobaric hypoxia (CIHH) can effectively alleviate type 2 diabetes mellitus (T2DM). In this process, the underlying mechanism in its association with the epigenetic regulation of DNA methylation in the promoter regions of glucose metabolism key enzyme genes remains unclear yet. Objective To investigate the effects of CIHH on expression and promoter region methylation of key enzyme genes related to glucose metabolism in diabetes mice, and to explore the underlying mechanism by which CIHH regulates glucose metabolism. Methods Forty C57BL/6J male mice were divided randomly into a normobaric normoxic control (NN/CON) group, a chronic intermittent hypobaric hypoxia intervention control (CIHH/CON) group, a normobaric normoxic diabetic model (NN/DM) group, and a chronic intermittent hypobaric hypoxia intervention diabetic model (CIHH/DM) group. The mice in the NN/DM and the CIHH/DM groups were fed for 7 weeks with high-fat and high-sugar diet. Subsequently, these mice were intraperitoneally injected consecutively with 50 mmol·L⁻¹ streptozotocin (STZ) for 5 d at a dose of 40 mg·kg⁻¹ (body weight) per day to create T2DM model mice. The mice in the CIHH/DM and the CIHH/CON groups were intervened by simulating hypobaric hypoxia at 5000 m altitude for 6 h per day, while the mice in the NN/DM and the NN/CON groups were always placed in a normobaric normoxic environment. All mice were continuously treated for 4 weeks, and blood glucose were monitored during this period. After the CIHH intervention experiment, the glucose tolerance and insulin sensitivity of mice were evaluated. A set of indicators involved in key glycolytic enzymes glucokinase (GK) and pyruvate kinase (PK), as well as key gluconeogenic enzymes phosphoenolpyruvate carboxyl kinase (PEPCK) and glucose-6-phosphatase (G6P) were measured in the liver of mice, including enzyme activity, relative mRNA expression level, and DNA methylation level in the gene promoter regions. Results Compared with the mice in the NN/DM group, the blood glucose levels of the mice in the CIHH/DM group decreased after the 25^th day of the CIHH intervention (P<0.05). Regarding the diabetic glucose tolerance curves, the area under the curve (AUC) of the mice in the CIHH/DM group was lower than that of the NN/DM group (P<0.05). Compared with the mice in the NN/DM group, the mice in the CIHH/DM group showed that the serum insulin content and HOMA of insulin resistance index (HOMA-IRI) decreased (P<0.05), the enzyme activities of GK and PK increased and the relative mRNA expression levels of their genes were up-regulated (P<0.05), while the enzyme activities of PEPCK and G6P decreased and the relative mRNA expression levels of their genes were down-regulated (P<0.05) in liver. The average DNA methylation levels in the promoter regions of GK, PK, PEPCK, and G6P genes in liver of mice in each group were not significantly different (P>0.05), and their correlations with mRNA expression levels were also not statistically significant (P>0.05). Conclusion CIHH intervention may reduce blood glucose level, improve glucose tolerance, alleviate insulin resistance, and regulate the key enzyme activities of glucose metabolism and the relative mRNA expression of their corresponding genes in T2DM mice, but the above phenomena are not related to the DNA methylation levels in the promoter regions of these key enzymes.

Objective To investigate the effect of the sling massage exercise on postpartum pelvic girdle pain(PPGP). Methods From March,2022 to May,2023,56 patients with PPGP in Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were randomly divided into control group(n=28)and observation group(n=28).Both groups received routine physical therapy and healthy education,while the control group received exer-cise therapy and the observation group received sling massage exercise,for six weeks.They were assessed with Visual Analog Scale(VAS),Pelvic Girdle Questionnaire(PGQ)and active straight leg raise(ASLR)test before and after treatment,and measured resting and contraction thickness of transversus abdominis with ultrasound;and integrated electromyography(iEMG),root mean square(RMS),median frequency(MF)and mean power fre-quency(MPF)of pelvic floor muscles with surface electromyography. Results After treatment,the total effective rate was 96.43%in the observation group and 78.57%in the control group(Z=2.728,P<0.05).All the indexes improved in both groups(|t|>2.080,P<0.05)except resting thickness of transverse abdominis muscle,and improved more in the observation group than in the control group(|t|>2.161,P<0.05). Conclusion The sling massage exercise can alleviate pain,enhance the stability of the core muscle group,and improve load transfer and quality of life,better than exercise therapy.

Objective:To analyze the clinical features of patients with cardic involvement in eosinophilic granulomatosis with polyangiitis (EGPA), and to enhance the understanding.Methods:We retrospectively reviewed the clinical data of 16 patients with EGPA with cardiac involvement in Bethune hospital of Shan-xi from Jan 2012 to Jun 2019. T test, rank sum test and χ2 test were used for statistical analysis. Results:16 patients with cardiac involvement. There were 11 males and 9 female. The age of 16 patients with cardiac involvement ranged from 14 to 82 years old, and the average age of onset was (58±14) years. Compared with patients without cardiac invo-lvement was (41±15) years, the difference between the two groups was statistically significant ( t=3.230 , P<0.01). The analysis suggested that age was related to whether or not cardiac involvement. Cardiac related clinical symptoms occurred in 4 patients (25%). One patient presented with cardiac involvement as the initial symptom. The other 12 patients presented abnormal electrocardiogram (ECG), cardiac ultrasound or cardiac magnetic resonance imaging (MRI), including 10 patients (62%) with abnormal ECG, 13 patients (81%) with abnormal cardiac ultrasound examination, and1patient with cardiac MRI suggesting endocarditis. Among 16 patients with EGPA cardiac involvement, 14 presented with pulmonary involvement, 10 cases with nasal involvement, 9 cases with perip-heral neurological involvement, 9 cases with skin involvement, 6 cases with gastrointestinal involvement, 2 cases with kidney damage. Eosinophils (EO) were increased in all 16 patients, with a median value of 2.46 (1.49, 3.94) ×10 9/L, and EO was associated with cardiac involvement. Analysis of perinuclear anti-neutrophil cytoplasmic antibo-dies (pANCA) positive rate showed that only 2 of the 16 patients were positive. There was statistically significant difference ( P=0.017) compared with the group without cardiac involvement (8 patients were positive). All 16 patients were treated with glucocorticoid, 12 patients received immunosuppressive therapy, and 10 patients were treated with cyclophosphamide. During the ollow-up, 1 case died of heart failure, 1 case died of cerebral hemorrhage, 3 cases were lost to follow-up, and the other 11 cases were all stable after discharge. Conclusion:EGPA patients have a high incidence of cardiac involvement, and all cardiac stru-ctures can be involved, and most cardic involvement happens in ANCA negative patients. Cardiac involvement is one of the factors with poor prognosis.

Objective To analyze the clinical features and treatment of connective tissue disease (CTD) complicated with acquired hemophilia A (AHA).Methods A retrospective analysis of 8 cases of CTD [5 cases of systemic lupus erythematosus (SLE),2 cases of Sj(o)gren's syndrome (SS),1 case of rheumatoid arthritis (RA)] related to clinical manifestations,diagnostic methods,treatment options and outcomes.Results At the onset of AHA,active disease was shown in 7 patients with CTD,and 5 cases had bleeding symptoms in different parts.There were 3 cases of anti-phospholipid syndrome in 5 cases of SLE,2 of which had thrombosis.In 8 patients,the activated partial thromboplastin time (APTF) was prolonged by 1.7 to 3.times,FⅧ∶ C was 9.2％ to 21％ (50％ to 150％),and the factor Ⅷ inhibitor titer was increased by 7.6 to 56 BU/m1 (Bethesda method).Seven patients were treated with sufficient hormones,immunosuppressive agents,human immunoglobulin (IVIG),and blood products.Five patients had clinically improved bleeding tendency and APIT,and one patient was ineffective.Conclusion CTD is easy to combine with AHA.Glucocorticoid combined with immunosuppressive agent can effectively treat CTD-related AHA.For refractory patients,rituximab can be an alternative.

Tumor cells have genetic instability, which ultimately leads to the production of different tumor cells with different gene mutations and different subclone manifestations. The coexistence mechanism and biological consequences of different subclones are extremely complex. Tumor cell subclones can carry out linear or branching evolution under different selection pressures. Tumor microenvironment is one of important selection pressures, which not only affects the evolution of tumor subclones, but also affects the growth of subclones and their interaction more widely. Tumor metastasis is a major reason for the poor prognosis of tumor patients. The low-frequency subclones in original tumor cells play an important role in the process of tumor metastasis. What subtle changes in tumor cells can make the transition of low-frequency subclones? It has become the focus of current study. This review focuses on the evolutionary patterns and influencing factors of tumor cell subclones in order to understand the subclones for guiding the clinical individual treatment.

Objective To study the influence of total flavonoids of hemerocallis fulva(TFHF) on hepatocyte apoptosis and related protein expression in mice with alcoholic hepatic injury.Methods A total of 40 mice were randomly divided into four groups:blank control,model control andsmall and high dose TFHF groups,10 cases in each group.The mice were given the continuous gavage administration for 7 d.Then the model group was given once gavage by 50％ ethanol 12.0 mL/kg after 1 h of the last administration.The blank control group was given the equal volume of distilled water.The activity levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum as well as the superoxide dismutase(SOD) activity and malondialdehyde (MDA) content in liver tissue hemogenate were detected.Hematoxylin and Eosin(HE) staining was performed for observing the pathological changes of the liver tissue.The flow cytometer was used to test the apoptosis ratio in hepatocyte suspension.The expressions of caspase-3,Bcl-2 and Bax protein were detected by Western blot.Results The various TFHF groups could decrease the activities of ALT and AST in serum (P＜0.05),while could decrease the MDA content in liver tissue hemogenate (P＜0.01) and increased the SOD activity;the liver tissue pathological examination showed that the high dose TFHF group could make the liver cell degeneration,alleviated the necrosis degree and relieved the pathological change of hepatic tissue;compared with the model group,the hepatocyte apoptosis rate in each TFHF group was decreased significantly;Western blotting results showed that the caspase-3 protein level in each TFHF group was decreased,expression of Bcl-2 protein was increased,whereas which of Bax protein was decreased and Bax/Bcl-2 ratio was reduced.Conclnsion TFHF has obvious protective effect on mice acute hepatic injury induced by ethanol,and can inhibit the hepatocyte apptosis,its action mechanism may be related to its antioxidation and regulation of caspase-3,Bcl-2 and Bax expression.

Objective Endothelial microparticles (EMPs) are direct indicator of endothelial cell activation or apoptosis,and may also reflect endothelial inflammation,increased coagulation,and vascular tone.The aim of this study is to investigate whether EMPs would be able to evaluate systemic involvement and be a new indicator of disease activity in Beh(c)et's disease (BD).Methods Thirty-nine consecutive BD patients (who fulfilled the modified International Study Group on BD in 1990 or International Criteria for BD in 2006) and 67 age and sex-matched healthy controls were enrolled (Including 37 patients with hypertension and 30 healthy subjects).The plasma levels of EMPs were measured by flow cytometry utilizing specific labels for endothelial MPs (CD31+ and CD42b-).The measurement data of each group were expressed as-x±s,and the comparison data betwen groups were analyzed by independent sample t test and analysis of variance,Spearman/Pearson correlation analysis,P＜0.05 was statistically significant.Results The levels of circulating EMPs (CD31 + and CI42b-) were significantly elevated in the case group compared with the healthy control group and hypertension (F=6.845,P＜0.05).Moreover,BD patients plasma EMPs were positively correlated with active BD (r=0.802,P＜0.05).Vascular involvement in BD patients was higher than in patients without vascular EMPs,t=4.707,P＜0.05.Gastrointestinal involvement in BD patients was more frequent than that in patients without Gastrointestinal involvement,t=2.673,P＜0.05.Conclusion Levels of circulating EMPs are elevatedd in BD patients and correlated with disease activity in BD.Elevated EMPs may be a potential indicator to predict disease activity of BD.The plasma level of EMPs is increased,which indicats increased risk of vascular and digestive tract involvement in BD.
