BACKGROUND: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China. METHODS: We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model. RESULTS: From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%). CONCLUSIONS CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.

OBJECTIVE: To investigate the predictive value of the prognostic nutritional index (PNI) and systemic inflammatory response index (SIRI) for short-term efficacy and prognosis in newly treated patients with peripheral T-cell lymphoma (PTCL). METHODS: The general data, laboratory indicators, disease stage and other clinical data of 91 newly treated PTCL patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2023 were retrospectively analyzed. The optimal cutoff values for PNI and SIRI were determined using receiver operating characteristic (ROC) curves, and the patients were stratified into groups based on these cutoffs to compare clinical features and short-term efficacy between the different groups. Kaplan-Meier method was used to plot survival curves, and univariate and multivariate analyses were performed to identify the factors affecting overall survival (OS). RESULTS: The optimal cutoff values for PNI and SIRI were 45.30 and 1.74×10⁹/L, respectively. Patients in different PNI groups showed statistically significant differences in age, Ann Arbor stage, lactate dehydrogenase (LDH) level, international prognostic index (IPI), prognostic index for PTCL-not otherwise specified (PIT), pathological subtypes, and complete response (CR) rate (P < 0.05). PTCL patients in different SIRI groups exhibited significant differences in Ann Arbor stage, LDH level, IPI score, PIT score, and CR rate (P < 0.05). Logistic regression analysis showed that age ≥60 years old (OR =2.750), Ann Arbor stage Ⅲ-Ⅳ (OR =5.200), IPI score ≥2 (OR =7.650), low PNI (OR =3.296), and high SIRI (OR =3.130) were independent risk factors affecting treatment efficacy in PTCL patients (P < 0.05). Cox proportional hazards regression model analysis showed that low PNI and elevated β₂-microglobulin (β₂-MG) levels were independent risk factors affecting OS (P < 0.05). CONCLUSION PNI and SIRI have certain application value in evaluating short-term efficacy and prognosis in patients with PTCL. Compared with SIRI, PNI demonstrates greater predictive value for patient prognosis.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective:To discuss the association between occupational acid fog exposure and accelerated biological aging of the workers,and to clarify its related risk factors.Methods:A total of 341 male workers exposed to occupational acid fog and 201 male workers without occupational exposure were selected as the study subjects,and they were divided into exposure group and control group,respectively.The general informations of the subjects in two groups were collected through questionnaires and physical examinations.The levels of red blood cell count(RBC),platelet count(PLT),albumin(ALB),urea(Urea),creatinine(CR),triglycerides(TG),total cholesterol(TC),glycated hemoglobin(HBA1c),and high-sensitivity C-reactive protein(Hs-CRP)in serum of the subjects in two groups were detected.The Klemera-Doubal method(KDM)was used to construct the composite aging measure,KDM-biological age(BA)(KDM-BA).The model parameters were trained using samples from the 2009 China Health and Nutrition Survey(CHNS)Database to calculate the BA acceleration of the subjects in two groups;stratified analysis based on the population characteristics was conducted to analyze the BA of the subjects in two groups with different population characteristics;generalized linear model was used to analyze the factors influencing BA acceleration due to acid fog exposure.Results:The model parameters were trained using samples from the 2009 CHNS Database,including 8 133 cases aged 20-79 years,of which 3 788 were male.The levels of Urea,CR,HBA1c,ALB,and TC,as well as systolic blood pressure(SBP),total working years,sleep duration,and body mass index(BMI)of the subjects between two groups had significant differences(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05).In entire population and exposure group,the BA acceleration in the smokers was significantly higher than that in the non-smokers(P<0.05).In entire population,control group,and exposure group,the BA accelerations of the subjects in different BMI groups were significantly decreased with the increase of BMI(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05),including those under 40 years old,with total working years of 4-7 years,Han nationality,unmarried,smokers,and sleep duration 6-7 h,and with overweight.Acid fog exposure,smoking,and BMI were associated with the BA acceleration(β=0.72,95%CI:0.24-1.21;β=0.59,95%CI:0.11-1.06;β=-0.29,95%CI:-0.35—-0.22).Conclusion:Occupational acid fog exposure may accelerate the biological aging in the workers,and acid fog is a risk factor to accelerate the biological aging of the body.

This study adopted the policy text analysis method,review the historical background of the enactment,aimed to comparatively analyze the international pharmaceutical trade policies of the BRICS countries.The main objectives of the BRICS countries'international pharmaceutical trade policies included ensuring stable and accessible drug supply,expanding exports of domestic products and creating a favorable political environment.For these purposes,Brazil,Russia,and South Africa all ensure drug supply through substantial imports.However,they have also taken measures such as compulsory patent licensing and promoting localization of production by foreign companies to reduce import dependence.India,on the other hand,protects its domestic industry by resisting drug imports to ensure drug supply while simultaneously promoting the export of pharmaceutical products.China continually optimizes approval and data monitoring procedures to align with international standards,creating a favorable trade environment and expanding exports.China should further refine its international pharmaceutical trade policies while ensuring the autonomy of domestic drug research and supply,fostering stronger collaboration within BRICS nations and promoting global access to public healthcare products.

A method for rapid,simultaneous determination of two metabolites of benzene,trans,trans-muconic acid (t,t-MA) and S-phenylmercapturic acid (S-PMA),in human urine by ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. Urine sample was acidified and protein was removed by acetonitrile precipitation. The supernatant was concentrated by nitrogen blowing and redissolved by solvent,and then analyzed by UPLC-MS/MS. The compounds were separated on a BEH C18 column with acidic ammonium formate solution and methanol solution as mobile phases for gradient elution and then quantified in multiple reaction monitoring (MRM) mode by internal standard method. Combined with the 96-well sample collection plate as a pre-treatment vessel,large quantities of samples could be rapidly analyzed. The linear ranges for detection of t,t-MA and S-PMA were 20-2000μg/L and 0.5-20μg/L,respectively,and the correlation coefficients were 0.9998. The limits of detection were 1.2 and 0.06μg/L,respectively. The recoveries were 90.6％-103.4％ and 87.3％-101.7％,and the relative standard deviations (RSDs) were in range of 1.5％-3.5％ and 1.8％-4.2％,respectively. The method was applied to detection of 41 urine samples of employees exposed to benzene. The detection rates of t,t-MA and S-PMA were 95％ and 78％,respectively. Compared with solid phase extraction method,this method showed many advantages such as simple operation,rapidity and high efficiency,high sensitivity and accuracy,which was suitable for rapid detection of t,t-MA and S-PMA in large quantities of urine samples.

AIM: To investigate the effect of orbital decompression on the central macular choroidal thickness(CMCT)in patients with thyroid-associated ophthalmopathy(TAO).METHOD: Prospective clinical studies. A total of 29 TAO patients(42 eyes)treated in our department from January 2021 to January 2022 were analyzed, and they were divided into 20 cases(30 eyes)in the moderate and severe group and 9 cases(12 eyes)in the extremely severe group. Both groups of patients received orbital decompression, and the changes of CMCT, visual acuity, intraocular pressure, exophthalmos, and clinical activity score(CAS)at 3 and 6mo before and after surgery were compared between the two groups.RESULTS: All patients completed follow-up. The CMCT, exophthalmos, intraocular pressure, and CAS of the extremely severe group at 3 and 6mo were 355.13±15.59 and 339.61±13.17μm, 19.33±2.23 and 17.83±1.70mm, 18.86±3.05 and 18.09±1.37mmHg, 3.75±0.87 and 2.42±1.00 points, respectively. The moderate and severe group was 325.00±10.48 and 321.04±11.34μm, 16.07±1.74 and 15.6±1.98mm, 16.65±2.04 and 16.03±2.3mmHg, 1.50±0.51 and 1.43±0.50 points, and there was differences with those before operation(extremely severe group: 396.46±17.61μm, 22.00±2.3mm, 21.85±2.82mmHg, 5.33±1.44 points; moderate and severe group: 335.77±11.60μm, 19.07±1.84mm, 18.89±3.06mmHg, 1.63±0.49 points; all P<0.001). The best corrected visual acuity(LogMAR)before surgery was 0.64±0.22 in the extremely severe group, and 0.43±0.20 and 0.34±0.15 at 3 and 6mo after operation, respectively, which were different from those before surgery(all P<0.001)CONCLUSION: Orbital decompression can effectively reduce CMCT, intraocular pressure and exophthalmos in TAO patients, relieve orbital vein stasis, and effectively improve vision and reduce mobility in patients with extremely severe disease.

OBJECTIVE: The study aimed to estimate the benchmark dose (BMD) of coke oven emissions (COEs) exposure based on mitochondrial damage with the mitochondrial DNA copy number (mtDNAcn) as a biomarker. METHODS: A total of 782 subjects were recruited, including 238 controls and 544 exposed workers. The mtDNAcn of peripheral leukocytes was detected through the real-time fluorescence-based quantitative polymerase chain reaction. Three BMD approaches were used to calculate the BMD of COEs exposure based on the mitochondrial damage and its 95% confidence lower limit (BMDL). RESULTS: The mtDNAcn of the exposure group was lower than that of the control group (0.60 ± 0.29 vs. 1.03 ± 0.31; P < 0.001). A dose-response relationship was shown between the mtDNAcn damage and COEs. Using the Benchmark Dose Software, the occupational exposure limits (OELs) for COEs exposure in males was 0.00190 mg/m ³. The OELs for COEs exposure using the BBMD were 0.00170 mg/m ³ for the total population, 0.00158 mg/m ³ for males, and 0.00174 mg/m ³ for females. In possible risk obtained from animal studies (PROAST), the OELs of the total population, males, and females were 0.00184, 0.00178, and 0.00192 mg/m ³, respectively. CONCLUSION Based on our conservative estimate, the BMDL of mitochondrial damage caused by COEs is 0.002 mg/m ³. This value will provide a benchmark for determining possible OELs.
