Organophosphorus pesticide(OP)is one of the most widely used pesticides in the world with the largest dosage.Acute organophosphorus pesticide poisoning(AOPP)is a common clinical disease,and AOPP accounts for 20%-50%of poisoning cases in China every year,with case fatality rate of 3%-40%.Bromophos(BDF)is a long-acting anticoagulant rodenticide,which inhibits vitamin K epoxide reductase and interferes with the synthesis of coagulation factorsⅡ,Ⅶ,Ⅸ and Ⅹ,leading to coagulation dysfunction.This article discusses the multidisciplinary diagnosis and treatment(MDT)process of a patient with combined poisoning of dichlorvos and bromadiolone.The article explores blood purification,management of coagulation abnormalities,secondary infection,atropinization and altered consciousnes in patients with organophosphorus poisoning and anticoagulant rodenticide compound poisoning,with the aim of providing clinicians with references for early diagnosis and treatment.

Objective : To characterize MMP12 as a pan-cancer marker and assess its screening value as a tumor serum marker. Methods : Bioinformatics tools such as GEPIA2,GSCA,cBioPortal,and GeneMANIA were used to analyze the pan-cancer features of MMP12 in TCGA datasets,including encompassing differential gene expression analysis,prognostic analysis,DNA methylation analysis,gene structural variation analysis and immune microenvironment analysis.Furthermore,serum samples we collected from patients with lung adenocarcinoma,breast invasive carcinoma,esophageal squamous cell carcinoma,stomach adenocarcinoma,liver hepatocellular carcinoma,and healthy individuals.ELISA was used to detect MMP12 expression in serum,and the screening performance was evaluated using the area under the ROC curve.Additionally,we followed up 28 ESCC patients and compared serum MMP12 levels between 19 patients with disease progression and 9 patients with stable disease. Results: The pancancer feature analysis revealed a significant negative correlation between MMP12 mRNA expression and its promoter DNA methylation(P<0.05),as well as a positive correlation with gene copy number variations(P<0.05).MMP12 mRNA expression was up-regulated in 14 cancer tissues compared to normal tissues next to cancer(P<0.05) and was associated with poor prognosis of cancer patients(P<0.05).Immunocorrelation analysis showed that MMP12 was significantly associated with immunity,infiltration of stromal cells,tumor mutational burden(TMB) and microsatellite instability(MSI)(P<0.05).ROC curve analysis indicated that MMP12 could serve as a potential biomarker for screening lung adenocarcinoma,breast invasive carcinoma,esophageal squamous cell carcinoma,stomach adenocarcinoma,and liver hepatocellular carcinoma.In a 30-month follow-up study of esophageal squamous cell carcinoma patients,the expression of MMP12 was higher in the disease progression group than that in the stable group. Conclusion MMP12 serves as a potential prognostic and screening marker of pan-cancer.

As a type of acute cerebrovascular disease,stroke is one of the most common fatal and disabling diseases in the world,which seriously threatens the quality of life of patients;however,there are still limited treatment methods for this disease in clinical practice.Traditional Chinese medicine(TCM)has a long history and good efficacy in the treatment of stroke,and the active components of TCM can alleviate nerve injury caused by stroke by improving the development and progression of various pathophysiological mechanisms such as nerve inflammation,oxidative stress,and blood-brain barrier damage.This article reviews the role of active components of TCM in the treatment of ischemic stroke,in order to provide more ideas and options for the clinical treatment of this disease in the future.

Objective To investigate the effect of field angle on the results of in vivo dose validation of electronic portal imaging device(EPID)in patients.Methods Design the mold test and analyze the influence of different mold thicknesses and different frame angles on the 2D γ pass rate.Twenty-three patients who un-derwent radiotherapy in the Department of Radiotherapy of Jinhua Municipal Central Hospital from January to June 2023 were selected as the research object.In vivo dose verification was carried out during treatment to obtain 2D γ pass rate using same-day sector beam CT(FBCT)of planned CT and executive image guided(IG-RT)as reference images,and the influence of field angle on pass rate was analyzed.Results When the frame angle was unchanged,the area of the shooting field was larger than 17 cm×17 cm,and the 2D γ passing rate decreased with the increase of the thickness.The frame angle had no effect on the 2D γ pass rate when the mold thickness was constant.In clinical treatment data,the passage rate of 2D γ near 0°/180° was higher than that near 90°/270°(P＜0.05),and the passage rate near 90°/270° in the FBCT group was higher than that in the IGRT group(P＜0.05).The median passing rate of 3 mm 2D γ was 97.97％in 3％of the 23 patients.The non-IGRT group was 96.81％,the IGRT group was 97.89％,the FBCT group was 98.94％.There was a statistically significant difference in 2D γ passing rate between the non-IGRT group and the IGRT group(Z=-5.083,P＜0.05),and there was a statistically significant difference in 2D γ passing rate between the IGRT group and the FBCT group(Z=-10.657,P＜0.05).Conclusion Clinically,the difference of pass rate in vi-vo dose verification at different rack angles is mainly due to the difference of images within and between ses-sions.Using same-day FBCT as the reference image for in-vivo dose verification can improve the accuracy of pass rate and eliminate the influence of image difference between sessions.

Objective To analyze the factors affecting patients with active tuberculosis(ATB)combined with acute pulmonary thromboembolism(APTE),in order to intervene the progression of the patients'disease early and improve the prognosis.Methods A total of 121 patients with ATB were studied.Forty-one cases with APTE diagnosed by CT pulmonary arteriography(CTPA)were in the ATB+APTE group,and 80 patients with ATB were in the ATB group.The general data of the two groups were collected and analyzed,including the differences in TB lesion sites and drug resistance,clinical manifestations and first laboratory indexes after admission.The influencing factors of ATB patients with concurrent APTE were analyzed by multifactorial Logistic regression,and continuous indexes with significant differences were selected,and the subjects'work characteristics(ROC)curves were plotted to assess the predictive value.Results Compared with the ATB group,patients in the ATB+APTE group were older,and Padua scores were higher,red blood cell distribution width(RDW),neutrophil-to-lymphocyte ratio(NLR),D-dimer were higher,the proportion of cough and expectoration increased and levels of partial pressure of carbon dioxide,hemoglobin(Hb),and albumin were lower(P＜0.05).Multifactorial Logistic regression analysis showed that higher Padua score,RDW and D-dimer were risk factors for patients with ATB combined with APTE,and the predicted area under the curve(AUC)for ATB combined with APTE were 0.657(95%CI:0.549-0.764)and 0.889(95%CI:0.827-0.951)for RDW and D-dimer,respectively.Conclusion In patients with ATB,the risk of combined APTE is increased with increased frequency of sputum and elevated Padua score,RDW and D-dimer,alerting to the development of APTE events.

Metabotropic glutamate receptor 5 (mGluR5) encephalitis is a rare type of anti-cell surface antigen antibody encephalitis mediated by autoimmune mechanisms. This article reported a case of anti-mGluR5 encephalitis. The patient was a 25-year-old young man with a history of Hodgkin′s lymphoma. Due to tumor recurrence, he developed encephalitis symptoms including fever, headache, mental and behavioral abnormalities, memory loss, consciousness disturbance, and seizures after checkpoint immunosuppressive therapy. He was finally diagnosed as anti-mGluR5 encephalitis by positive serum anti-mGluR5 antibodies. Finally, the symptoms alleviated after treatment with hormones and gamma globulin.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

Background::Joint dislocations significantly impact public health. However, a comprehensive study on the incidence, distribution, and risk factors for joint dislocations in China is lacking. We conducted the China National Joint Dislocation Study, which is a part of the China National Fracture Study conducted to obtain the national incidence and risk factors for traumatic fractures, and to investigate the incidence and risk factors for joint dislocations.Methods::For this national retrospective epidemiological study, 512,187 participants were recruited using stratified random sampling and probability-proportional-to-size method from January 19 to May 16, 2015. Participants who sustained joint dislocations of the trunk, arms, or legs (skull, sternum, and ribs being excluded) in 2014 were personally interviewed to obtain data on age, educational background, ethnic origin, occupation, geographic region, and urbanization degree. The joint-dislocation incidence was calculated based on age, sex, body site, and demographic factors. The risk factors for different groups were examined using multiple logistic regression.Results::One hundred and nineteen participants sustained 121 joint dislocations in 2014. The population-weighted incidence rate of joint dislocations of the trunk, arms, or legs was 0.22 (95% confidence interval [CI]: 0.16, 0.27) per 1000 population in 2014 (men, 0.27 [0.20, 0.34]; women, 0.16 [0.10, 0.23]). For all ages, previous dislocation history (male: OR 42.33, 95% confidence interval [CI]: 12.03–148.90; female: OR 54.43, 95% CI: 17.37–170.50) and alcohol consumption (male: OR 3.50, 95% CI: 1.49–8.22; female: OR 2.65, 95% CI: 1.08–6.50) were risk factors for joint dislocation. Sleeping less than 7 h/day was a risk factor for men. Compared with children, women aged ≥15 years (female 15–64 years: OR 0.16, 95% CI: 0.04–0.61; female ≥65 years: OR 0.06, 95% CI: 0.01–0.41) were less likely to sustain joint dislocations. Women with more than three children were at higher dislocation risk than women without children (OR 6.92, 95% CI: 1.18–40.78).Conclusions::The up-to-date data on joint dislocation incidence, distribution, and risk factors can be used as a reference for national healthcare, prevention, and management in China. Specific strategies for decreasing alcohol consumption and encouraging adequate sleeping hours should be developed to prevent or reduce dislocation incidents.Trial Registration::Chinese Clinical Trial Registry, ChiCTR-EPR-15005878.
