Objective:To explore the association of blood and urinary cadmium levels with lipid profile levels and dyslipidemia in Chinese adults aged 18 to 79 years.Methods:Based on the China National Human Biomonitoring (CNHBM) program, a cross-sectional survey was conducted from 2017 to 2018 using a multi-stage stratified random sampling method, including a total of 10 713 adults aged 18 to 79 years. Data was obtained through questionnaires, physical examinations, biological sample collection, and laboratory testing. Multiple linear mixed effect model (MLMM) and generalized linear mixed effect model (GLMM) were used to analyze the association of blood and creatinine-corrected urinary cadmium levels with lipid profile levels as well as dyslipidemia among adults.Results:The age of 10 713 participants was (47.23±0.24) years, with 5 372 males accounting for 61.3% of the national population. The weighted mean±standard error (SE) of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) was (5.21±0.03), (1.86±0.03), (2.96±0.03), and (1.43±0.01) mmol/L, respectively. The prevalence rate of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, low HDL-C, and high LDL-C was 16.0%, 21.6%, 6.6%, 13.5%, and 10.0%, respectively. MLMM showed that, after adjusting for relevant confounders, log-transformed blood cadmium levels were positively associated with increased levels of TC, TG and LDL-C ( P<0.05). When blood cadmium levels were categorized into quartiles, compared to the lowest exposure group ( Q1), participants in the highest blood cadmium exposure group ( Q4) had increases of 0.19 (95% CI: 0.06, 0.32) mmol/L in TC and 0.25 (95% CI: 0.08, 0.43) mmol/L in TG. GLMM indicated that, after adjusting for confounders, higher blood cadmium exposure levels were associated with increased risks of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and high LDL-C ( P<0.05). Further analysis by quartiles showed that, compared to the blood cadmium Q1 exposure group, the OR value (95% CI) for the Q4 group was 1.53 (1.12, 2.08) for hypercholesterolemia, 1.54 (1.09, 2.17) for hypertriglyceridemia, 2.24 (1.47, 3.40) for mixed hyperlipidemia, and 1.49 (1.07, 2.09) for high LDL-C. Conclusion:The cadmium internal exposure levels are associated with blood lipid profile levels as well as the incidence of dyslipidemia in Chinese adults aged 18 to 79.

[Objective]To investigate the effect of blue light on emmetropization in guinea pigs,explore the potential mechanisms and assess its application in myopia prevention and control.[Methods]Three-week-old male guinea pigs(n=20)were randomly assigned to the white light group and the blue light group.Refraction and ocular biological parameters were measured every 2 weeks until the experiment ended at week 8.And the 4D-data-independent acquisition(4D-DIA)proteomics technology was used to analyze retina from both the blue light and white light groups,exploring protein composition,expression differences,and biological functions.[Results]After 2 weeks,Guinea pigs exposed to white light gradually tended towards emmetropia,showing a statistically significant difference in refractive error compared to the blue light group(P<0.001).From week 4,the axial length of the blue light group was significantly shorter than that of the white light group(P<0.05).Meanwhile,the vitreous chamber length in the blue light group was significantly smaller than that of the white light group from week 2(P<0.05).A total of 161 differentially expressed proteins were identified by proteomics technology in the retina,with 98 proteins upregulated and 63 proteins downregulated.These proteins were primarily enriched in biosynthetic pathways such as vesicle transport,redox reaction,niacin and nicotinamide metabolism and NAD+metabolism.[Conclusions]Guinea pigs raised under blue light exhibit hyperopic drift and slowed axial elongation,which slows the procession of emmetropization.Based on the 4D-DIA technology,the differentially expressed proteins between the blue light and white light groups are primarily involved in NAD+metabolism,niacin and nicotinamide metabolism.Especially in NAD+salvage synthesis,nicotinamide phosphoribosyl transferase(NAMPT)is upregulated,while sirtuin 2(SIRT2)is downregulated.It provides new insights into the mechanism of blue light in emmetropization and a theoretical basis for myopia prevention and control.

To analyze a case of severe avian influenza A (H5N6) virus infection resulting in severe pneumonia and acute respiratory distress syndrome (ARDS) was admitted to Guilin Municipal Hospital of Traditional Chinese Medicine on July 6, 2023. The clinical data and treatment of this patient were analyzed retrospectively. The initial clinical manifestations of the patient were fever, cough, and expectoration, and the antigen test for influenza A virus was positive. Chest CT showed: double lung texture increased and thickened, and multiple patchy high-density shadows with air-containing bronchial shadows were found in the left lung, especially in the left upper lobe; a few patchy increased-density shadows were also seen in the lower lobe of the right lung, along with left-sided pleural effusion. Metagenomic next-generation metagenomic sequencing (mNGS) of bronchoalveolar lavage fluid was performed to identify the pathogen as influenza A virus H5N6. On the 4th day of admission, the patient's condition rapidly progressed to ARDS, which could not be improved by high-flow oxygen therapy, mechanical ventilation, and prone position ventilation. Subsequently, with the assistance of veno-venous extracorporeal membrane oxygenation (VV-ECMO), the patient's lung function gradually improved. Extracorporeal membrane oxygenation(ECMO) was withdrawn after 25 days, and the patient recovered and was discharged after a hospital stay of 41 days. Patients with severe avian influenza A (H5N6) usually have critical illness and rapid progression, often rapidly progressing to ARDS. When conventional mechanical ventilation cannot correct hypoxemia, VV-ECMO auxiliary treatment should be administered as early as possible. In addition, mNGS can help to quickly identify the diagnosis and differential diagnosis of avian influenza A (H5N6) in the early stage of the disease, particularly suitable for the diagnosis of severe and emergency infections.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.

Objective To evaluate the value of postoperative prophylactic radiotherapy for N0 e-sophageal squamous carcinoma. Methods From January 1993 to December 2006,859 patients with patho-logically staged N0 and M0 esophageal squamous cell carcinoma were included in this study. Among them, 760 received surgery alone, and 99 received surgery followed by postoperative radiotherapy. Radiotherapy started within 3 to 4 weeks after surgery. The median total dose was 50 Gy(2 Gy/F,5 F/w). Results In surgery alone group and postoperative radiotherapy group,the 5-yeur overall survival rotes were 72.2% vs 77.4% (X2 =0. 13,P >0.05) for all patients,34.6% vs67.1% (X2 =7.72,P <0.05) forpT4 disease,and 70.2% vs 81.3% (X2 =4.01 ,P <0.05) for tumor length >5 cm. Postoperative radiotherapy could lower the recurrence rate for pT4 patients. Conclusions For patients with NO esophageal squamous carcinoma, postoperative radiotherapy can significantly improve the survival for pT4 and tumor length > 5 cm,and also re-duce the recurrence for pT4 patients.

Objective To compare the accuracy of CT with other methods to measure the length of thoracic esophageal carcinoma. Methods 598 patients with thoracic esophageal squamous carcinoma were enrolled in this study.All the patients received three-field(cervical,thoracic:and abdominal)radical surgery without pre-operative radiotherapy or chemotherapy.The length of each Iesion was recorded and compared by measuring intraoperative specimen,formalin-fixed specimen,X-ray barium meal examination and CT,respectivelv. Results By the measurement of intraoperative specimen,formalin-fixed specimen,Xray barium meal examination and CT,the mean lengths of lesion were(5.22±1.94),(4.28±1.71),(5.12±1.92)and(6.71±2.52) cm,respectively.The measured length was significantly different between intraoperative specimen and formalin-fixed specimen or CT(t=16.01,P<0.01;t=-15.54,P<0.01),but not between intraoperative specimen and X-ray barium meal examination(t=1.62,P>0.05).The measured lengths gradually decreased in the order of CT,intraoperative specimen,X-ray bailam meal examination and formalin-fixed specimen.For different pathological type(except intracavitary type)and different T staging,there was significant difference in lesion length between intraoperative specimen and CT(P<0.05),but not between intraoperative specimen and X-ray barium meal examination(P>0.05). Conclusions The length of esophageal carcinoma measured by intraoperative specimen is shorter than by CT,but longer than by X-ray barium meal examination.Specimen could shrink after foriBalin fixation.X-ray barium meal and other examinations should be referred when using CT to delineate tumor target volume of esophageal carcinoma for radiotherapy.
