Objective: To analyze the association between alcohol consumption and lumbar disc herniation (LDH), so as to provide a reference for the development of prevention and treatment strategies for LDH. Methods: From May to July 2022, permanent residents aged ≥18 years from eight counties (cities/districts) in Gansu Province were selected using a multistage stratified random sampling method. Data on basic characteristics, alcohol consumption in the past 30 days, hypertension, and diabetes mellitus were collected through questionnaire surveys. LDH was determined based on imaging findings, combined with disease history or clinical symptoms. Multivariable logistic regression model was used to analyze the association between alcohol consumption and LDH, with subgroup analyses conducted by gender, age, ethnicity, and altitude of residence. Propensity score matching (PSM) was utilized for sensitivity analysis. Results: A total of 4 545 individuals were surveyed. There were 2 026 (44.58%) males and 2 519 (55.42%) females. The mean age was (44.82±15.33) years. The study participants were predominantly of Han ethnicity, with 2 598 persons accounting for 57.17%. The altitude of residence was mainly above 3 500 m, with 1 941 persons accounting for 42.71%. There were 574 alcohol drinkers, accounting for 12.63%. LDH was detected in 1 035 cases, with a detection rate of 22.77%. Multivariable logistic regression analysis showed that after adjusting for gender, age, physical activity, and hypertension, compared to non-drinking residents, alcohol-consuming residents exhibited a 27.6% reduction in the risk of LDH (OR=0.724, 95%CI: 0.544-0.963). No significant interaction effects on LDH risk were observed between alcohol consumption and gender, age, ethnicity, or altitude of residence (all Pfor interaction >0.05). The results of the sensitivity analysis indicated that compared to non-drinking residents, alcohol-consuming residents exhibited a 38.8% reduction in the risk of LDH (OR=0.612, 95%CI: 0.382-0.976). Conclusion Alcohol consumption was statistically associated with a lower risk of LDH.

Objective:To investigate the predictive value of systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), and CT perfusion imaging (CTP) parameters for early neurological deterioration (END) in patients with mild stroke duo to anterior circulation large vessel occlusion.Methods:Patients with minor stroke duo to anterior circulation large vessel occlusion admitted to the First People's Hospital of Suqian from November 2021 to December 2023 were included. Minor stroke was defined as a baseline National Institutes of Health Stroke Scale (NIHSS) score ≤ 5, and END was defined as an increase of ≥ 4 in NIHSS score within 24 hours of admission compared to the baseline. SIRI and SII were calculated based on the findings of blood routine examination. According to CTP at admission, the cerebral blood volume (CBV) index, infarct core volume, and early infarct growth rate (EIGR) were obtained. Multivariate logistic regression analysis was used to determine the independent risk factors for END. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of each predictor on END. Results:A total of 132 patients were included, with 85 males (64.4%) and a median age of 68 years (interquartile range, 58-77 years). Thirty-nine patients (29.5%) experienced END. The baseline NIHSS score, fasting blood glucose, neutrophil count, lymphocyte count, SIRI, SII, infarct core volume, and EIGR in the END group were significantly higher than those in the non-END group, while the CBV index was significantly lower than that in the non-END group (all P<0.05). Multivariate logistic regression analysis showed that SIRI (odds ratio [ OR] 3.672, 95% confidence interval[ CI] 1.838-6.326; P<0.001), SII ( OR 4.824, 95% CI 2.057-7.135; P<0.001), CBV index ( OR 0.968, 95% CI 0.947-0.986; P<0.001), and EIGR ( OR 2.527, 95% CI 1.918-3.589; P<0.001) were the independent predictive factors of END. ROC curve analysis showed that the area under the curves of SIRI, SII, CBV index, and EIGR for predicting END were 0.780 (95% CI 0.692-0.863), 0.798 (95% CI 0.709-0.888), 0.775 (95% CI 0.697-0.853), and 0.772 (95% CI 0.732-0.829), respectively. Conclusion:SIRI, SII, CBV index, and EIGR are the independent predictive factors of END in patients with minor stroke duo to anterior circulation large vessel occlusion, and have certain predictive value for END.

Objective:To explore the long-term efficacy of laparoscopic fundoplication for proton pump inhibitor dependent gastroesophageal reflux disease (GERD).Method:Clinical data of proton pump inhibitor dependent GERD patients who underwent fundoplication at the Rocket Force Characteristic Medical Center from Jan to Jun 2012 were analyzed, including GERD symptom score, subjective symptom relief rate, PPI discontinuation rate and surgical satisfaction, as well as recurrence and complications.Result:A total of 160 GERD patients were included in this study, with 64% of patients having respiratory symptoms. Nissen and Toupet fundoplication were performed in 43 and 117 cases, respectively, with a follow-up time of (127±3) months. The postoperative GERD symptom scores of the patients were significantly lower than before treatment (all P<0.001); The subjective relief of overall symptoms in the digestive tract and airway problem was 90% (80%, 100%) and 100%, respectively. The PPI discontinuation rate was 86%, and the overall satisfaction rate of the treatment was 92%, and the satisfaction rate of patients with respiratory symptoms was 89%. 7% of patients experienced varying degrees of symptomatic recurrence, 4% of patients re-underwent endoscopic treatment and/or laparoscopic fundoplication due to symptom recurrence. The incidence of long-term postoperative dysphagia, bloating, belching, increased exhaust, abdominal pain, diarrhea, and constipation were 11.3%, 16.9%, 0, 1.3%, 0, 2.5%, and 5.6%, respectively. Conclusions:Laparoscopic fundoplication has good long-term efficacy in the treatment of GERD. A small number of patients may experience postoperative recurrence, as well as complications such as dysphagia and gas-bloat syndrome. Most recurrent patients can achieve good therapeutic effect by redoing endoscopic treatment or redoing surgery.

It is recommended to accurately position and optimize the function of Internet hospital, establish the incentive mechanism for online consultation doctors, construct and improve the regulatory system of Internet hospital diagnosis and treatment, so as to improve the accessibility and quality of diagnosis and treatment of Internet hospitals.

Objective To investigate the effects of total flavonoids from Vine tea on the intestinal flora of high-fat diet(HFD)induced non-alcoholic fatty liver disease(NAFLD)mice.Methods Twenty-eight mice were randomly divided into four groups:blank control group,model control group(HFD group),low-dose TF group(TF-L group),and high-dose TF group(TF-H group),with 7 mice in each group.Mice in the HFD group,TF-L group,and TF-H group were fed with high-fat diet(HFD)for 12 weeks,while those in the blank control group were fed a normal diet.After 12 weeks of high-fat diet feeding,mice in the TF-L group and TF-H group were orally administered TF solution at doses of 125 and 250 mg·kg-1·d-1 by gavage administration for 6 weeks of intervention.Pathological changes in the liver and intestine of mice were observed using hematoxylin-eosin(H&E)staining,and the expression levels of tight junction proteins between the epithelial cells of the colonic mucosa was analyzed by immunohistochemistry.ELISA kit was used to detect the level of serum inflammatory factors in mice.Changes of intestinal flora in mice were analyzed by 16S rRNA sequencing technology.Results Total flavonoids from Vine tea could effectively improve the pathological changes of liver and intestinal tract in mice,reduce the levels of serum inflammatory factors IL-6 and TNF-α,and promote the expression of tight junction proteins Occludin,ZO-1 and Claudin 1 in the colon.There were significant differences in the intestinal flora of the three groups of mice.Total flavonoids from Vine tea significantly decreased the ratio of Firmicutes to Bacteroidota(P＜0.05),increased the abundance of Faecalibaculum,Ligilactobacillus and Lactobacillus,which resulted in the improvement of intestinal flora disorders.Conclusion Total flavonoids from Vine tea have certain ameliorative effects on high-fat diet-induced NAFLD,and the mechanism may be related to the promotion of intestinal barrier repair and the improvement of intestinal flora disorders.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the value of CT quantitative parameters of tumor and spleen in predicting the clinical stage of gastric cancer (Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage).Methods:This study was a case-control study. The data of 145 patients with gastric cancer confirmed by pathology in the First Affiliated Hospital of Zhengzhou University from February 2019 to June 2021 were retrospectively collected, including 70 cases of Ⅰ/Ⅱ stage and 75 cases of Ⅲ/Ⅳ stage. On the baseline CT images, the tumor related parameters, including tumor thickness, length of tumor, CT attenuation of tumor unenhanced phase, CT attenuation of tumor arterial phase, CT attenuation of tumor venous phase were measured. The spleen related parameters, including splenic thickness, CT attenuation of splenic unenhanced phase, CT attenuation of splenic arterial phase, CT attenuation of splenic venous phase, and standard deviation of CT attenuation (CTsd) in splenic unenhanced phase were also measured. The independent sample t test or Mann-Whitney U test was used to compare the parameters between the Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage patients. The multi-factor logistic regression analysis was used to find the independent predictors of gastric cancer clinical stage, and establish the combined parameters. The efficiency to the diagnosis of gastric cancer stage of single and combined parameters was evaluated using the operating characteristic curve, and the DeLong test was used to compare the differences of area under the curve (AUC). Results:There were significant differences in tumor thickness, length of tumor, CT attenuation of tumor venous phase, CT attenuation of splenic unenhanced phase, CT attenuation of splenic venous phase, CTsd in splenic unenhanced phase between the Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage of gastric cancer ( P<0.05). Multivariate analysis showed that tumor thickness ( OR=1.073, 95% CI 1.026-1.123, P=0.002), CT attenuation of splenic venous phase ( OR=1.040, 95% CI 1.011-1.070, P=0.006) and CTsd in splenic unenhanced phase ( OR=1.625, 95% CI 1.330-1.987, P<0.001) were independent risk factors for the clinical stage of gastric cancer and the combined parameters were established. The AUC values of tumor thickness, CT attenuation of splenic venous phase, CTsd in splenic unenhanced phase and combined parameters were 0.655, 0.614, 0.749 and 0.806, respectively. The AUC of combined parameters was higher than those of tumor thickness and CT attenuation of splenic venous phase, and the differences were statistically significant ( Z=3.37, 3.82, both P<0.001). Conclusion:Tumor thickness, CT attenuation of splenic venous phase and CTsd in splenic unenhanced phase are independent risk factors for the clinical stage of gastric cancer, and combined parameters can improve the diagnostic efficiency.

ObjectiveThe potential suitable area for ecological planting， key ecological factors， and suitable range of Polygonatum odoratum in China were analyzed to provide theoretical and scientific guidance for the artificial planting of P. odoratum. MethodA total of 454 geographical distribution records of P. odoratum in China and 118 ecological factors were used in this study. The maximum entropy model （MaxEnt） was adopted to predict the suitable areas of P. odoratum. The key ecological factors and their suitable ranges were analyzed by the jackknife method， contribution rates of ecological factors， and response curves. ResultThe suitable areas of P. odoratum were mainly located in the northwest， north， and northeast of China， the highly suitable areas of which were concentrated in Shaanxi， Shanxi， Gansu， etc. Solar radiation in November （Srad11）， precipitation in July （Prec7）， percentage of evergreen/deciduous needleleaf trees （Class1）， silt content （2-50 μm） mass fraction （SLTPPT）， and annual average temperature （Bio1） were found to be the key ecological factors affecting the suitable distribution of P. odoratum in China. The cumulative contribution rate of solar radiation factors （31.29%）>vegetation factors （25.61%）>soil factors （19.52%）>precipitation factors （11.38%）>temperature factors （8.57%）>topography factors （3.63%）. ConclusionIt is suggested to carry out ecological planting of P. odoratum mainly in Shaanxi （such as Baoji and Ankang Cities and Ningshan， Liuba， and Hua Counties）， Gansu （such as Tianshui City， Gannan Tibetan Autonomous Prefecture， and Liangdang and Huating Counties）， and Shanxi （such as Yangquan， Taiyuan， Fenyang， and Jinzhong Cities， as well as Xingxian County） of China. Solar radiation factors should be given priority in the planting process， followed by vegetation， soil， precipitation， temperature， and topography factors. The range of key ecological factors， namely Srad11， Prec7， Class1， SLTPPT， and Bio1 should be controlled within 8 095.21-10 334.98 （optimum 8 787.50） kJ·m^-2·d^-1， 109.99-223.60 （146.91） mm， 1.00%-9.45% （6.76%-10.68%）， 41.73%-50.35% （46.53%）， and 3.29-16.33 （13.57） °C， respectively.

Background Pesticide exposure may impact the reproductive health of women undergoing assisted reproductive technology (ART). However, data on pesticide exposure levels in women undergoing ART in China are scarce, and current research on influencing factors is limited. Objective To evaluate the preconceptional pesticide exposure levels and identify potential determinants among women undergoing ART. Methods This study was designed as a cross-sectional survey and recruited 508 women undergoing ART from July 2017 to December 2018 at the fertility clinic of the International Peace Maternity and Child Health Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Gas chromatography/liquid chromatography-tandem mass spectrometry was used to determine the metabolite concentrations of organophosphate pesticides (OPs), pyrethroid pesticides (PYRs), and neonicotinoid pesticides (NEOs) in urine. The sum of molar concentrations of the three pesticide classes (∑₂OPs, ∑₂PYRs, and ∑₂NEOs) were calculated. A questionnaire was used to collect demographic characteristics, dietary habits, and behavioral information. Multiple linear regression was employed to analyze the associations of demographic characteristics, dietary habits, and behavioral variables with the concentrations of pesticide metabolites in urine among the participants. Results The median creatinine-adjusted concentrations of ∑₂OPs, ∑₂PYRs, and ∑₂NEOs in this study were 419.77, 2.95, and 20.36 nmol·g⁻¹, respectively. The multiple linear regression results showed that the urinary concentration of ∑₂OPs was 42.88% higher in the participants with daily vegetable intake than in those who consumed vegetables ≤3 d per week (P<0.05), and the urinary concentration of ∑₂PYRs was 37.24% higher in the participants with daily fruit intake than in those who consumed fruits ≤3 d per week (P<0.01). Similarly, the urinary concentrations of ∑₂NEOs were 24.51% and 29.30% higher in the participants who consumed fruits daily and 4-6 d per week, respectively, than in those who consumed fruits ≤3 d per week (P<0.05). Besides, we also found that the urinary concentration of ∑₂PYRs was negatively correlated with body mass index (BMI) in the participants (P<0.05). Furthermore, the urinary concentration of ∑₂NEOs was not only positively correlated with age (P<0.05), but also significantly associated with pet ownership and infertility causes among the participants. Specifically, the participants who continued to own pets after conception had a 30.11% higher urinary concentration of ∑₂NEOs than those who never owned pets (P<0.05), and the participants with infertility due to female factors had a 24.10% lower urinary concentration of ∑₂NEOs than those who received ART treatment for infertility caused by male factors (P<0.05). Conclusion The women undergoing ART in Shanghai are widely exposed to pesticides. Age, BMI, frequency of vegetable and fruit intake, pet ownership, and infertility causes may be related to the pesticide exposure levels in this population. However, more human data are needed to confirm these findings.

Objective To observe the value of clinical and CT radiomics features for predicting microsatellite instability-high(MSI-H)status of gastric cancer.Methods Totally 150 gastric cancer patients including 30 cases of MSI-H positive and 120 cases of MSI-H negative were enrolled and divided into training set(n=105)or validation set(n=45)at the ratio of 7∶3.Based on abdominal vein phase enhanced CT images,lesions radiomics features were extracted and screened,and radiomics scores(Radscore)was calculated.Clinical data and Radscores were compared between MSI-H positive and negative patients in training set and validation set.Based on clinical factors and Radscores being significant different between MSI-H positive and negative ones,clinical model,CT radiomics model and clinical-CT radiomics combination model were constructed,and their predictive value for MSI-H status of gastric cancer were observed.Results Significant differences of tumor location and Radscore were found between MSI-H positive and negative patients in both training and validation sets(all P＜0.05).The area under the curve(AUC)of clinical model,CT radiomics model and combination model for evaluating MSI-H status of gastric cancer in training set was 0.760,0.799 and 0.864,respectively,of that in validation set was 0.735,0.812 and 0.849,respectively.AUC of clinical-CT radiomics combination model was greater than that of the other 2 single models(all P＜0.05).Conclusion Clinical-CT radiomics combination model based on tumor location and Radscore could effectively predict MSI-H status of gastric cancer.
