ObjectiveTo explore the correlation between the occurrence of cardiovascular events in rheumatoid arthritis（RA） and traditional Chinese medicine（TCM） syndrome. MethodsThe cross-sectional study selected 6713 RA patients from 122 centres nationwide， in which general information such as name， gender， age， height， body weight， and course of disease were collected by completing a questionnaire； patients were classified into eight types of syndrome according to the information of their four examinations，i.e. wind-dampness obstruction syndrome， cold-dampness obstruction syndrome， dampness-heat obstruction syndrome， phlegm-stasis obstruction syndrome， stasis-blood obstructing collateral syndrome， qi-blood deficiency syndrome， liver-kidney insufficiency syndrome， and qi-yin deficiency syndrome. According to the occurrence of cardiovascular events， they were divided into the occurrence group and the non-occurrence group， and the condition assessment data and laboratory examination indexes were recorded. The test of difference between groups was used to analyse the possible risk factors for the occurrence of RA cardiovascular events， and binary logistic regression was used to analyse the correlation between TCM syndromes and RA cardiovascular events. ResultsA total of 6713 RA patients were included， including 256 cases in occurrence group and 6457 in non-occurrence group. There was no statistically significant difference between groups in terms of height， gender， insomnia， appetite， white blood cell（WBC）， hemoglobin（HGB）， platelets（PLT）， rheumatoid factor（RF）， anti-cyclic peptide containing citrulline（CCP）， alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， γ-glutamyl transpeptidase（GGT）， urea creatinine（CREA）， and glucose（GLU）（P＞0.05）. The TCM syndromes between groups showed significant statistic differences（P＜0.05）. Patients in occurrence group had longer disease duration， heavier body weight， and older age； more severe conditions such as disease activity（DAS-28）， number of painful joints（TJC）， number of swollen joints（SJC）， health questionnaire scores（HAQ）， visual analog scores（VAS）， restlessness， and fatigue； higher blood sedimentation rate（ESR）， low-density lipoprotein（LDL-C）， triglyceride（TG）， total cholesterol（TC）， D-Dimer， and lower high-density lipoprotein（HDL-C）（P＜0.05）. The distribution of syndrome types showed that dampness-heat obstruction syndrome accounted for the largest proportion of patients in both groups and was higher in RA cardiovascular events. Logistic regression analysis showed that the occurrence of RA cardiovascular events was strongly associated with dampness-heat obstruction syndrome［OR=5.937， 95%CI （4.434， 7.949）， P＜0.001］. ConclusionThe occurrence of RA cardiovascular events were associated with TCM syndromes， and the probability of cardiovascular events in the RA patients with dampness-heat obstruction syndrome was 5.937 times higher than patients with other TCM syndromes.

The Department of Thoracic Surgery of Shanghai Chest Hospital has performed esophageal function testing for over 30 years, being the only department of its kind in China with this capability. The pressure testing and 24-hour pH/impedance monitoring of the esophagus is of great help to assist in the diagnosis and treatment of benign and malignant esophageal diseases related to it. Thanks to the esophageal function test, in addition to the routine various endoscopic anti-reflux procedures, our hospital has taken the lead in China in recent years to carry out a series of clinical and research work for benign esophageal diseases, such as the development of magnetic ring, double nedoscopic combination and new anti-reflux endoscopic techniques. In recent years, we have carried out high-resolution esophageal manometry and 24-hour pH/impedance monitoring for patients with interstitial pneumonia and pulmonary fibrosis suspected to be caused by gastroesophageal acid reflux. We can better assess the correlation between gastroesophageal reflux and pulmonary fibrosis, and to provide the different clinical treatments and even surgical interventions. The Bravo capsule is used more often in the United States, and it has obvious advantages over traditional approach for acid measurement. We strongly call for the collaboration between industry and academic institutions in this field, and the development of our own related products with independent intellectual property rights.

Objective:To study the correlation of uridine diphosphate glucuronosyl transferase 1A1(UGT1A1) gene polymorphism and neonatal hyperbilirubinemia among Dai ethnic group in Yunnan province.Methods:From January 2020 to December 2022, Dai neonates with unexplained neonatal hyperbilirubinemia admitted to three hospitals in Yunnan Province were prospectively enrolled into the hyperbilirubinemia group. Neonates hospitalized during the same period without hyperbilirubinemia were selected as the control group. The serum total bilirubin levels were measured and UGT1A1 gene sequencing was performed in all neonates. The differences of genotype frequency and allele frequency of UGT1A1 gene in the two groups were analyzed. Logistic regression analysis was used to analyze the effects of each mutation on hyperbilirubinemia among Dai neonates.Results:A total of 92 neonates were in the hyperbilirubinemia group and 86 in the control group. No significant differences existed between the two groups on following items: gender, age at admission, gestational age (GA), birth weight (BW), feeding pattern, white blood cell count (WBC) and hemoglobin level ( P>0.05).Three mutation loci were detected in the hyperbilirubinemia group (c.211G>A, c.1091C>T and c.1456T>G), with frequencies 45.7%, 3.3% and 2.2%, respectively. Two mutation loci were detected in the control group (c.211G>A and c.1091C>T), with frequencies 17.4% and 1.2%. Correlation analysis showed that c.211G>A frequency (45.7%) and A allele frequency (23.9%) in the hyperbilirubinemia group were significantly higher than the control group ( P<0.05). No significant differences existed in the frequencies of c.1091C>T and c.1456T>G between the two groups ( P>0.05). Logistic regression analysis showed that c.211G>A was risk factor of unexplained neonatal hyperbilirubinemia in Dai neonates ( OR=3.976, 95% CI 1.991-7.941). Conclusions:The most common mutation of UGT1A1 gene in Chinese Dai neonates with unexplained neonatal hyperbilirubinemia in Yunnan Province is c.211G>A, which increases the risk of hyperbilirubinemia.

Pathology is the gold standard for diagnosis of neoplastic diseases.Whole slide imaging turns traditional slides into digital images,and artificial intelligence has shown great potential in pathological image analysis,especially deep learning models.The application of artificial intelligence in whole slide imaging of lung cancer involves many aspects such as histopathological classification,tumor microenvironment analysis,efficacy and survival prediction,etc.,which is expected to assist clinical decision-making of accurate treatment.Limitations in this field include the lack of precisely annotated data and slide quality varying among institutions.Here we summarized recent research in lung cancer pathology image analysis leveraging artificial intelligence and proposed several future directions.

Objective:To explore the the evaluation value of stress hyperglycemia ratio (SHR), C-reactive protein (CRP), and serum procalcitonin (PCT) for postoperative infection in patients with open tibiofibular fractures.Methods:This study was a prospective analysis. Patients with open tibiofibular fractures hospitalized in the Department of Orthopaedic Surgery of The Second Hospital of Tangshan and North China University of Science and Technology Affiliated Hospital from January 2018 to January 2023 were collected as the research objects, and a total of 839 cases were assessed for outcome, which were divided into infection group (103 cases) and non-infection group (736 cases) according to whether the selected subjects had postoperative infection. The clinical data of the two groups were analyzed by univariate analysis, and the risk factors of postoperative infection of open fracture of tibia and fibula were analyzed by multivariate Logistic regression, and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive efficacy of SHR, CRP, PCT, and their combined models on adverse outcomes.Results:Univariate analysis showed that the infection group had SHR (1.82±0.31), CRP (92.28±36.07) mg/L, PCT (6.35±1.79) μg/L, the non infection group had (1.05±0.12), (56.35±10.21) mg/L and (2.17±0.41) μg/L, respectively, and there were significant differences between the two groups ( t values were 46.90, 21.60, and 54.17, respectively; all P<0.001). The proportion of albumin (<30 g/L) in the infection group was higher than that in the non-infection group (63.11%(65/103), 37.64%(277/736) (χ 2=24.28, P<0.001), and the two groups had significant differences in the rate of time from injury to operation (the infection group ≥6 h was 71.84%(74/103), <6 h was 28.16%(29/103); the non-infection group ≥6 h was 43.07%(317/736), <6 h was 56.93%(419/736); χ 2=35.37, P<0.001), the rate of Gustilo-Anderson classification (the infection group Ⅰ、Ⅱ was 44.46%(46/103), ⅢA was 33.98%(35/103), ⅢB was 12.62%(13/103), ⅢC was 8.47%(9/103);the non-infection groupⅠ、Ⅱ was 59.10%(435/736), ⅢA was 32.47%(239/736), ⅢB was 5.98%(44/736), ⅢC was 2.45%(18/736); χ 2=20.34, P<0.001) and the rate of postoperative drainage volume (the infection group was 40.60%(48/103),the non-infection group was 58.02%(427/736); χ 2=4.79, P=0.029). Multivariate Logistic regression analysis showed that SHR ( OR=1.871,95% CI 1.621-2.160, P<0.001), CRP ( OR=1.060, 95% CI 1.015-1.107, P=0.009), PCT ( OR=1.497, 95% CI 1.420-1.577, P<0.001) were independent risk factors for postoperative infection in open tibiofibular fractures. Among them, SHR had the highest OR value, which was the strongest factor affecting the outcome of the study. Other independent factors were age ( OR=1.052, 95% CI 1.038-1.066, P<0.001) and Gustilo-Anderson type-ⅢC ( OR=1.875, 95% CI 1.038-2.015, P<0.001). By drawing the ROC curve of SHR, CRP, PCT and their combined model to predict the incidence of postoperative infection in open tibiofibular fractures, the results showed that the combined model had higher diagnostic predictive value than the single application, and its sensitivity and specificity were 86.4% and 70.4%, respectively, which were higher than the sensitivity (78.6%, 77.7%, 75.7%) and specificity (69.2%, 69.3%, 69.6%) of the single assessment. Conclusion:The combined model of SHR, CRP and PCT has a higher predictive value than the single detection, which can provide a better clinical basis for the early diagnosis of postoperative infection in patients with open tibiofibular fractures.

BACKGROUND:Trauma-induced coagulopathy(TIC)due to serious injuries significantly leads to increased mortality and morbidity among elderly patients.However,the risk factors of TIC are not well elucidated.This study aimed to explore the risk factors of TIC in elderly patients who have major trauma. METHODS:In this retrospective study,the risk factors for TIC in elderly trauma patients at a single trauma center were investigated between January 2015 and September 2020.The demographic information including gender,age,trauma parts,injury severity,use of blood products,use of vasopressors,need of emergency surgery,duration of mechanical ventilation,length of stay in the intensive care unit(ICU)and hospital,and clinical outcomes were extracted from electric medical records.Multivariate logistic regression analysis was performed to differentiate risk factors,and the performance of the model was evaluated using receiver operating characteristics(ROC)curves. RESULTS:Among the 371 elderly trauma patients,248(66.8%)were male,with the age of 72.5±6.8 years,median injury severity score(ISS)of 24(IQR:17-29),and Glasgow coma score(GCS)of 14(IQR:7-15).Of these patients,129(34.8%)were diagnosed with TIC,whereas 242(65.2%)were diagnosed with non-TIC.The severity scores such as ISS(25[20-34]vs.21[16-29],P<0.001)and shock index(SI),(0.90±0.66 vs.0.58±0.18,P<0.001)was significantly higher in the TIC group than in the non-TIC group.Serum calcium levels(1.97±0.19 mmol/L vs.2.15±0.16 mmol/L,P<0.001),fibrinogen levels(1.7±0.8 g/L vs.2.8±0.9 g/L,P<0.001),and base excess(BE,-4.9±4.6 mmol/L vs.-1.2±3.1 mmol/L,P<0.001)were significantly lower in the TIC group than in the non-TIC group.Multivariate logistic regression analysis revealed that ISS>16(OR:3.404,95%CI:1.471-7.880;P=0.004),SI>1(OR:5.641,95%CI:1.700-18.719;P=0.005),low BE(OR:0.868,95%CI:0.760-0.991;P=0.037),hypocalcemia(OR:0.060,95%CI:0.009-0.392;P=0.003),and hypofibrinogenemia(OR:0.266,95%CI:0.168-0.419;P<0.001)were independent risk factors for TIC in elderly trauma patients.The AUC of the prediction model included all these risk factors was 0.887(95%CI:0.851-0.923)with a sensitivity and specificity of 83.6%and 82.6%,respectively. CONCLUSION:Higher ISS(more than 16),higher SI(more than 1),acidosis,hypocalcemia,and hypofibrinogenemia emerged as independent risk factors for TIC in elderly trauma patients.

Objective:To investigate the predictive value of fluid-attenuated inversion recovery (FLAIR) signal strength ratio (SIR) in onset time≤4.5 h in patients with acute ischemic stroke.Methods:A retrospective analysis was performed; 180 acute ischemic stroke patients admitted to Department of Neurology, Nanjing Hospital Affiliated to Nanjing Medical University from January 2020 to June 2023 were chosen. Hypoperfusion intensity ratio (HIR) was used to evaluate the collateral circulation (poor collateral circulation: HIR≤0.4; good collateral circulation: HIR>0.4); clinical data and imaging indexes between poor collateral circulation and good collateral circulation groups were compared. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for onset time≤4.5 h in patients with acute ischemic stroke. Correlation between SIR and onset time was analyzed in patients with acute ischemic stroke. Role of HIR as agency between SIR and onset time was explored. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of SIR and diffusion weighted imaging (DWI)-FLAIR mismatch in onset time≤4.5 h in acute ischemic stroke patients.Results:Of the 180 patients, 100 were into the good collateral circulation group and 80 were into the poor collateral circulation group; compared with the good collateral circulation group, the poor collateral circulation group had significantly higher percentage of patients with hyperlipidemia, larger DWI infarction volume before treatment, larger perfusion weighted imaging (PWI)-DWI mismatch volume and higher SIR ( P<0.05). In these 180 patients, 76 had onset time≤4.5 h and 104 had onset time>4.5 h. Univariate Logistic regression analysis showed that hyperlipidemia, DWI infarct volume before treatment, DWI-FLAIR mismatch, HIR and SIR were influencing factors for onset time≤4.5 h in acute ischemic stroke patients ( P<0.05). Multivariate Logistic regression analysis showed that hyperlipidemia ( OR=6.654, 95% CI: 5.751-8.824, P<0.001), HIR ( OR=0.724, 95% CI: 0.521-1.321, P=0.041) and SIR ( OR=739.881, 95% CI: 383.296-14 258.065, P<0.001) were independent influencing factors for onset time≤4.5 h in acute ischemic stroke patients. Pearson correlation analysis showed that SIR was positively correlated to onset time in patients with acute ischemic stroke ( r=0.420, P<0.05), and SIR was positively correlated to onset time in patients from poor collateral circulation group ( r=0.781, P<0.05). ROC curve showed that AUC of SIR in predicting onset time≤4.5 h was 0.917 (95% CI: 0.814-1.000, P<0.001) and that of DWI-FLAIR mismatch in predicting onset time≤4.5 h was 0.530 (95% CI: 0.509-0.757, P=0.075) in poor collateral circulation group, enjoying significant difference in predictive efficacy. Conclusion:Acute ischemic stroke patients with low HIR and SIR have higher odds of onset time≤4.5 h; SIR can more accurately predict the onset time in these patients with poor collateral circulation.

ObjectiveTo evaluate the clinical efficacy and safety of Tripterygium wilfordii polyglycoside tablets （TWP） in the treatment of rheumatoid arthritis （RA） in the real world. MethodDiagnosis and treatment data of patients with RA in Chinese medicine rheumatology registration research information platform information database （CERTAIN） from January 1，2019 to January， 2024 were collected. According to the inclusion and exclusion criteria， data were screened. The included data were divided into an exposure group and a control group according to the use of TWP or not. Propensity score matching （PSM） was used in both groups to keep the baseline balanced and comparable. The disease activity score （DAS28-ESR） of 28 joints based on the erythrocyte sedimentation rate （ESR）before and after treatment was compared between the two groups， as well as health assessment questionnaire （HAQ），visual analogue scale （VAS），tender joint count （TJC），swollen joint count （SJC）， patient's global assessment （PGA），evaluator's global assessment （EGA），laboratory indexes， clinical curative effect， and adverse reactions. ResultA total of 3 978 patients were included，including 929 in the exposure group and 3 049 in the control group. Before PSM，there were significant differences in demographic information，DAS28-ESR score，PGA，EGA，HAQ，VAS scores，SJC， and TJC between the two groups （P<0.05）. After successful PSM matching，922 patients in the exposure group and 922 patients in the control group were included. There was no significant difference in demographic information and DAS28-ESR between the two groups before treatment，and the differences in other indexes between the two groups decreased to varying degrees. After treatment，the DAS28-ESR，PGA，EGA，HAQ，SJC，TJC，VAS scores， ESR，and IgG immune index of the two groups were significantly lower （P<0.01）. Compared with those in the control group after treatment，the DAS28-ESR，PGA，EGA，HAQ，VAS scores， and ESR in the exposure group after treatment decreased more significantly （P<0.05，P<0.01）. There was no significant difference in TJC in the exposure group after treatment. However， TJC in the exposure group was significantly higher than that in the control group before treatment （P<0.05）. In terms of TJC reduction，the exposure group performed better than the control group. There was no significant difference in SJC and IgG between the exposure group and the control group after treatment. After treatment，the clinical symptoms of poor appetite，insomnia and many dreams，upset，fatigue，and fear of wind and cold in the two groups were improved. Except that the proportion of women in the exposure group was higher than that in the control group （P<0.01），there was no significant difference in the incidence of other adverse reactions between the two groups after treatment. ConclusionTWP to treat RA can effectively reduce DAS28-ESR，PGA，EGA，HAQ，TJC，and VAS scores and improve the general symptoms. Except for the women at childbearing age with fertility requirements that TWP is not applicable，it shows good security.

Objective: To understand family food environment and its associated factors of primary and secondary school students in Tongzhou District, so as to provide reference for the improvement of family food environment of primary and secondary school students in Tongzhou District. Methods: From 2021 to 2023, a stratified cluster sampling method was used to conduct a questionnaire survey on 1 485 families of students from 11 schools in Tongzhou District. Single Factor Analysis of Variance (ANOVA) was used to compare the differences in family food environment across different demographic background, and the associated factors were analyzed by the multiple binary Logistic regression model. Results: The average score of family food environment of primary and secondary school students in Tongzhou District was 64.32(12.28) points, and the total compliance rate (≥60 points) was 67.41%. The score of family feeding pattern [58.33 (11.11) points] and the compliance rate (42.76%) ranked the bottom among the five dimensions of family food environment. Rural families (OR=1.78, 95%CI=1.41-2.25), junior high schools (OR=1.42, 95%CI=1.07-1.87), senior high schools (OR=2.28, 95%CI=1.73-3.00), singleparent families (OR=1.89, 95%CI=1.15-3.10) and obese parents (OR=1.81, 95%CI=1.23-2.65) had a higher risk of substandard family food environment (P<0.05). Conclusions Family food environment of primary and secondary school students in Tongzhou District is not optimistic, family feeding mode needs to be improved. Attention should be paid to the family food environment, so as to effectively promote healthy growth of children and adolescents.
