ABSTRACT
Objective:To analyze the clinical characteristics of long-term survival patients with advanced non-small cell lung cancer (NSCLC) treated with chemotherapy combined with primary tumor radiotherapy, and to establish a Nomogram prognostic model, aiming to provide a certain reference for making a decision about the treatment of advanced NSCLC.Methods:A retrospective analysis was made on the data of 260 NSCLC patients who participated in two prospective clinical studies from January 2003 to May 2012 and the data of 138 NSCLC patients admitted to the Affiliated Cancer Hospital of Guizhou Medical University from January 2014 to August 2020. The former 260 cases were used as a training set and the latter 138 cases were used as the validation set. The overall survival (OS) of ≥ 18 months was defined as long-term survival (LTS). The clinical characteristics of LTS patients were compared with those with OS less than 18 months. The clinical characteristics and treatment-related parameters between the two types of patients were compared using the χ2 test. A multivariate analysis was made using logistic regression, and a nomogram model was built using RStudio. Results:The median OS of the training set was 13.4 months (95% CI: 11.9-14.9), with 1-, 2-, and 3-year OS rates of 55.4%, 19.1%, and 11.9%, respectively. In the training set, 87 cases had LTS and were classified as the LTS group, while 173 cases had OS less than 18 months and were classified as the non-LTS group. The univariate analysis showed that the prognostic factors affecting LST included the KPS score, T status, the number of metastatic organs, the number of metastatic lesions, brain metastasis, bone metastasis, the number of chemotherapy cycles, the biologically effective dose (BED) to the primary tumor, hemoglobin level, platelet count, plasma D-dimer, fibrinogen level, lactate dehydrogenase, and lung immune prognostic index (LIPI; χ2=4.72-12.63, P < 0.05). The multivariable analysis showed that the independent prognostic factors of LTS included a number of chemotherapy cycles ≥ 4, BED ≥ 70 Gy, platelets ≤ 220×10 9/L, D-dimer ≤ 0.5 mg/L, and a good LIPI score ( P= 0.002, 0.036, 0.005, 0.008, and 0.002). A nomogram model was established using the meaningful parameters obtained in the multivariable analysis, determining that the training and validation sets had a consistency index (C-index) of 0.750 and 0.727, respectively. As shown by the analytical result of the corrected curves, for the advanced NSCLC patients treated with thoracic radiotherapy, their LTS probability predicted using the nomogram prognostic model was highly consistent with their actual LTS probability. Both the analytical result of the receiver operating characteristic (ROC) curves and the decision curve analysis (DCA) result showed that the composite prediction model was more beneficial than a single prediction model. Conclusions:For patients with advanced NSCLC treated with thoracic radiotherapy, the independent prognostic factors of LTS included the number of chemotherapy cycles, BED, platelet count, pre-chemotherapy D-dimer, and LIPI score. The Nomogram prognostic model built based on these prognostic factors is a convenient, intuitive, and personalized prediction model used to screen patients who can benefit from thoracic radiotherapy.
ABSTRACT
Objective:To analyze the frequency and characteristics of polymyositis (PM) in idiopathic inflammatory myopathy (IIM), and to investigate whether PM is over-diagnosed.Methods:Patients diagnosed as IIM according to the Bohan & Peter criteria of IIM hospitalized in the Department of Rheumatology of China-Japan Friendship Hospital from 2008 to 2019 were involved in the study. Definite PM (dPM) was defined as typical clinical and pathological features including elevated creatine kinase (CK) level, muscle weakness and muscle biopsy findings with endomysial CD8 + T cell infiltration and expression of MHC-1 on sarcolemma. Meanwhile, dermatomyositis (DM), anti-synthase syndrome(ASS), immune-mediated necrotic myopathy(IMNM), sporadic inclusion body myositis(sIBM) and other myopathies were excluded according to the new classification criteria of IIM subtypes respectively. Statistical analysis was performed using SPSS software 24.0. The Kruskal-Wallis test and χ2 test were used to compare the clinical characteristics between the dPM group and other IIM subtypes. Results:A total of 1 259 patients with IIM including 1 015 (80.6%) DM and 244(19.4%) PM were enrolled in this study. According to the strict definition of PM criteria, only 0.5% of patients (6/1 259) in IIM could be diagnosed as dPM. Most PM patients were IMNM and ASS according to the new IIM subtypes criteria, of which 48.0% (117/244) were IMNM and 32.0% (78/244) were ASS. 66.7%(4/6) of dPM patients were women. One complicated with RA, and one was dPM overlaped with systemic sclerosis. All of them had muscle weakness, mild elevation of CK level [611(391,1 451) U/L], and were myositis-specific autoantibodies negative. Except one dPM patients who did not receive immunoregulatory therapy due to chronic obstructive pulmonary disease, the others were administrated with low or medium dose prednisone combined with or without immunosuppressive agents. After a median follow-up of (38±26) months, the muscle strength of dPM patients were improved.Conclusion:dPM is a very rare clinical subtype of IIM. PM is an over-diagnosed entity in clinical practice. Patients with dPM have mild symptoms and good outcome.
ABSTRACT
Objective:To investigate the value of the ultrasonography in the diagnosis of the white matter injury of premature infants based on gray-scale ultrasonography radiomics.Methods:A total of 256 premature infants in Huazhong University of Science and Technology Union Shenzhen Hospital and Shenzhen Hospital of Southern Medical University from August 2018 to April 2022 were analyzed retrospectively. The computer-generated random numbers were assigned to the training set and the verification set according to 6∶4 ratio. On the basis of standardized collection of craniocerebral ultrasound images, the radiomics features were extracted from imaging by Pyradiomics 3.0.1 software package, the Mann-Whitney U test and the least absolute shrinkage and selection operator (LASSO) and stepwise regression were used to select the optimal features. Then the Logistic regression was used to build radiomics model. According to MRI, ROC curve was utilized to evaluate the performance of the model. The craniocerebral ultrasound images in the validation set were independently diagnosed by a senior physician and a junior physician, and then the above two physicians diagnosed again with the help of the radiomics, and the diagnostic abilities of this model were compared with those of the junior and senior physicians with and without radiomics assist. Results:A total of 5 optimal features were selected to develop radiomics model. The sensitivity, specificity, accuracy and the area under the ROC curve (AUC) in the training and validation sets were 0.861, 0.775, 0.799, 0.818; 0.929, 0.824, 0.853, 0.876, respectively. The sensitivity, specificity, accuracy and AUC in the senior sonographer, the junior sonographer, and both of them with radiomics assist for the dagnosis in the validation set were 0.929, 0.892, 0.902, 0.910; 0.714, 0.743, 0.735, 0.729; 0.929, 0.919, 0.922, 0.924; 0.857, 0.824, 0.833, 0.841, respectively. Performance of radiomics model reached the level of the senior sonographer (AUC: 0.876 vs 0.910, P=0.284), which was significantly better than the performance of the junior sonographer(AUC: 0.876 vs 0.729, P=0.001). Performance of the junior sonographer with radiomics assist was significantly better than the performance of the junior sonographer(AUC: 0.841 vs 0.729, P=0.003). Performance of the senior sonographer with radiomics assist was comparable to that of the senior sonographer(AUC: 0.924 vs 0.910, P=0.156). Conclusions:The ultrasound diagnosis method based on radiomics technology shows good diagnostic performance for the white matter injury of premature infants. It is helpful to improve the diagnostic ability of junior sonographer. It is expected to assist the sonographers in diagnosis and provide objective, consistent and accurate results for clinical practice.
ABSTRACT
During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
ABSTRACT
Objective:To observe the efficacy of self-help cognitive behavioral therapy for insomnia (CBTI), trazodone hydrochloride and their combination in the treatment of depression and insomnia comorbidity in the elderly.Methods:90 elderly patients with insomnia and depression admitted to the 901th Hospital of the Joint Logistic Support Force from October 2019 to October 2021 were selected as the study subjects. They were divided into trazodone group, CBTI group and trazodone combined with CBTI group(combination group), with 30 cases in each group. Trazodone group was treated with oral trazodone hydrochloride, CBTI group was treated with self-help CBTI, and the combination group was treated with oral trazodone hydrochloride combined with self-help CBTI. All three groups were treated for 4 weeks. The sleep latency, total sleep time and sleep efficiency of each group were compared at the time of admission and after 4 weeks of treatment. Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used for sleep assessment before and after treatment, and Self-Rating Depression Scale (SDS) was used for depression assessment.Results:Before treatment, there was no significant difference among the three groups in terms of sleep latency, total sleep time, sleep efficiency, PSQI, ESS and SDS (all P>0.05). After treatment, the sleep latency of the three groups was shorter than that before treatment, and the total sleep time was longer than that before treatment (all P<0.05). The sleep efficiency of the trazodone group and the combination group was higher than that before treatment, with statistically significant difference (both P<0.05). The indexes of the combined group were better than those of the trazodone group and the CBTI group (all P<0.05). The sleep latency of the trazodone group was shorter than that of the CBTI group, and the total sleep time was longer than that of the CBTI group (all P<0.05), with statistically significant difference (all P<0.05). After treatment, the PSQI, except for the SDS of CBTI group, the ESS and SDS of the three groups were lower than those before treatment (all P<0.05). The PSQI, ESS and SDS of the combined group were lower than those of the trazodone group and the CBTI group, and the ESS and SDS of the trazodone group were lower than those of the CBTI group, with statistically significant difference (all P<0.05). Conclusions:For the elderly patients with depression and insomnia, the combination of self-help CBTI and trazodone can not only improve insomnia but also relieve depression symptoms, and the effect is better than that of trazodone and self -help CBTI alone.
ABSTRACT
Objective To investigate the epidemic situation of measles in Yichang from 2009 to 2021, and to provide scientific evidence for the control and elimination of measles. Methods Descriptive epidemiological methods were used to analyze the case data of measles cases reported by the notifiable infectious disease reporting system and measles surveillance system in Yichang from 2009 to 2021. Results A total of 364 cases of confirmed measles were reported in Yichang from 2009 to 2021, with an average annual incidence rate of 0.68/100 000. During these years, the incidence rates fluctuated from 0.5 to 28.87/100 000. The epidemic peak of measles was from January to July. Most cases were concentrated in five regions including Xiling, Wujiagang, Yiling, Dangyang and Yidu, accounting for 66.48% of all cases. More male cases were reported. The age of these patients ranged from < 1 month to 68 years, in which a great majority were infants (32.14%) and adults between 20 and 49 years old (48.08%). The five most common occupations of measles patients were scattered children, farmers, housekeeping or unemployed, workers and students, with the scattered children being the highest proportion accounting for 42.58%. There were 72 cases (19.78%) with the history of measles vaccine immunization, 113 cases (31.04%) without the immunization history, and 179 cases (49.18%) with unknown immunization history. Conclusion Incidence rates of measles in Yichang remains at a low level from 2009 to 2021. Young age groups and adults are the key groups for measles prevention and control. Strategies and measures such as immune strengthening for key areas and key populations will help improve the effect of measles prevention and control.

Conclusions:The long time of catheter use, palliative treatment, hematological tumor, neutropenia and chemotherapy were the risk factors of implantable venous access port-related bloodstream infection in patients with tumor, Medical personnel should make a good assessment and strengthen health education to minimize the chances of infection and effectively reduce the incidence of infection related to the infusion port.
ABSTRACT
Cancer-associated fibroblasts (CAFs) is considered as a key factor for the severely limited efficacy in tumor radiotherapy. CAFs, as the primary stromal cells in the tumor microenvironment, can lead to tumor radiotherapy resistance by secreting a series of pro-tumor cytokines and nutrients, inhibiting anti-tumor immune response and remodeling extracellular matrix. Some progress has been made in the study of targeted CAFs sensitization radiotherapy, but the relevant study system is still imperfect. Therefore, a systematic exploration of the role of CAFs in tumor radiotherapy resistance and CAFs targeted therapy strategies can provide a basis for improving the current status of tumor radiotherapy resistance.
ABSTRACT
Gastroesophageal reflux disease (GERD) is one of the most common digestive diseases with high incidence, complicated clinical symptoms, difficulties in standard treatment, and heavy medical burden. At present, some GERD-relevant clinical practice guidelines (CPGs) have been issued by different countries and academic organizations, but some recommendations were inconsistent, which has caused some problems for the current clinical whole-course management of GERD. To summarize the relevant evidence among the CPGs on GERD and formulate the whole- course management strategies, we included GERD-relevant CPGs published or updated after 2010 by searching websites of guidelines, relevant professional societies, and electronic databases. We extracted the recommendations and summarized the evidence from the aspects of symptoms, epidemiology, diagnosis and treatment, which was presented in the form of evidence mapping. We included 24 CPGs, including three in Chinese and 21 in English. The clinical practice management strategies of GERD were formulated based on the evidence from the aspects of clinical symptoms, diagnostic methods, medical treatment, anti-reflux surgery and endoscopic treatment, psychological treatment, and traditional Chinese medicine treatment.

BackgroundGender and age differences in the clinical manifestations of patients with bipolar disorder can affect the clinical diagnosis and treatment process. The current treatment effect of bipolar disorder in adolescents is not ideal， which has become the main reason for disability during the learning period. ObjectiveTo analyze the clinical features and medication therapy status of bipolar disorder in adolescents， and to provide references to support for personalized diagnosis and treatment. MethodsOn January 16， 2023， 1 169 patients with bipolar disorder who were hospitalized at Beijing Anding Hospital Affiliated Capital Medical University from January 1， 2014 to December 31， 2017 were retrospectively enrolled. Medical records were collected and analyzed to compare the clinical features among patients of different gender and age groups， and to explore the differences in medication use among patients of different genders in different types of seizures. ResultsMale patients reported a larger proportion of manic episodes， and a smaller proportion of depressive episodes than female patients （P<0.05）.Female patients reported a larger proportion of non-suicidal self-harm behaviors than male patients （χ2=7.761， P<0.01）.And patients in low-age group featured a larger proportion of mixed seizures， impulsive behaviors and family history of bipolar disorders along with a smaller proportion of manic episodes than those in high-age group （P<0.05 or 0.01）. High-age group had a longer average length of hospital stay than low-age group （t=-2.930， P<0.01）. In manic episode patients， males were found to have a larger proportion of valproate and atypical antipsychotic drug administration than females （P<0.01）. Among atypical antipsychotic drugs， males accounted for a larger proportion of administration of risperidone and olanzapine （χ2=26.957） than females （P<0.05 or 0.01）， while females constituted a larger proportion of administration of quetiapine （χ2=14.865） and aripiprazole than males （P<0.01）. In depressive episode patients， females had a larger proportion of administration of olanzapine than males （P<0.01）. In patients with mixed seizures， females occupied a larger proportion of administration of lithium carbonate than males （χ2=9.253， P<0.01）， and males exhibited a larger proportion of administration of valproate than females （P<0.05）. ConclusionDifferences have been shown in diagnostic classification and concomitant symptoms among adolescent bipolar disorder of different genders and ages. Furthermore， medications of lithium carbonate， valproate， atypical antipsychotic and other drugs differ by gender among adolescents of different subtypes of bipolar disorder. ［Funded by Key Special Project of the National Key R&D Program of the Ministry of Science and Technology for "Major Chronic Non communicable Disease Prevention and Control Research" （number， 2017YFC1311101）］
ABSTRACT
Objective: To evaluate the right ventricular function using two-dimensional speckle tracking echocardiography (2-D STE) and analyze the associated risk factors of right ventricular dysfunction in patients with silicosis. Methods: All 104 patients with silicosis treated in the Department of Occupational Medicine and Toxicology in Beijing Chao-Yang Hospital, Capital Medical University from May 2021 to September 2022 were enrolled in this study in October 2022. The clinical information of patients such as general data, arterial blood gas analysis and pulmonary function test were collected. The right ventricular function of patients was evaluated by 2-D STE-derived right ventricular free wall longitudinal strain (RVFWLS) and conventional echocardiographic-derived parameters, including right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE) and doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'), respectively. Based on their RVFWLS, the patients were divided into right ventricular dysfunction group and normal right ventricular function group. Risk factors for right ventricular dysfunction in patients with silicosis were analyzed using binary logistic regression analysis. Results: A total of 104 silicosis patients were enrolled, with aneverage age (65.52±11.18) years old, among whom including 57 cases diagnosed with stage Ⅰ/Ⅱ silicosis and 47 cases diagnosed with stage Ⅲ silicosis. 26 (25.00%) patients concurrent right ventricular dysfunction. The abnormal rates of RVFAC, TAPSE and S' in patients were 16.35% (17 cases), 21.15% (22 cases) and 6.73% (7 cases), respectively. The RVFAC and TAPSE in right ventricular dysfunction group were lower than those in normal right ventricular function group, and the incidence of pulmonary arterial systolic pressure ≥36 mmHg was higher than that in normal right ventricular function group (P<0.05). Logistic regression analysis showed that arterial partial pressure of oxygen (OR=0.932, 95%CI: 0.885-0.981, P=0.007) was the protective factor, and the forced expiratory volume in 1 second (FEV(1)) /forced vital capacity (FVC) ratio<70% (OR=5.484, 95%CI: 1.049-28.662, P=0.044) and stage Ⅲ silicosis (OR=6.343, 95%CI: 1.698-23.697, P=0.007) were the risk factors for silicosis patients concurrent right ventricular dysfunction. Conclusion: The incidence of right ventricular dysfunction is higher in patients with stage Ⅲ silicosis than that in patients with stage Ⅰ/Ⅱ silicosis. Using 2-D STE can help the early detection of silicosis with right ventricular dysfunction. Hypoxemia, airflow limitation and the stage Ⅲ silicosis are the risk factors for silicosis patients concurrent right ventricular dysfunction.

Objective: To understand the late reporting and the under-reporting of occupational disease from 2018 to 2020 in China and analyze the causes, so as to provide scientific evidence for improving the quality of occupational disease reports in China, timely acquiring the incidence of occupational disease, and assessing the occupational hazards. Methods: From May to December 2021, A total of 320 occupational disease diagnostic institutions were selected for investigation. The original documents of occupational disease diagnosis cases from 2018 to 2020 were compared with the online reported cases, and late reported and under-reported cases of occupational disease were analyzed. Results: A total of 32207 diagnosed cases from 2018 to 2020 were investigated, including 28934 confirmed cases and 3273 cases without occupational disease. The overall late reported rate and under-reported rate of confirmed cases were 20.2% and 2.1%, respectively. There were significant differences in the rate of late reporting and under-reporting of occupational diseases in different regions and different types of diagnostic institutions (P<0.001). The southwest region had the highest rates of late reporting and under-reporting, 61.6% and 7.9% respectively. The late reported rate of all kinds of occupational diseases was about 15.0%, and the under-reported rate was from 1.5.0% to 5.0%. Conclusion: At present, the phenomenon of late reporting and under-reporting occupational diseases is still obvious. It is necessary to strengthen the inspection of occupational disease reporting, improve the quality of occupational disease reporting, and provide scientific basis for the formulation of occupational disease prevention and control policies.

Objective: To understand the exposure level of dust and noise in the mining industry and provide data support for revising policy for the prevention and control of occupational diseases. Methods: In May 2022, Data was collected through the National Surveillance Program for Occupational Hazards in the Workplace. Descriptive analysis was conducted for dust and noise levels by industry type and enterprise size from 7, 679 enterprises in the mining industry among 29 provincial regions nationwide. Results: The enterprises in the mining industry included in the National Surveillance Program for Occupational Hazards in the Workplace are mainly small and micro, accounting for 47.97% (3684/7679) and 30.00% (230/7679) respectively. The industry is mainly compred of employers in the non-metallic ming and beneficiation industry, accounting for 50.25% (3859/7679). Among the enterprises with silica dust, coal dust, and noise hazards, the proportion of enterprises where total dust concentration and noise intensity exceed the standard is higher than 50%. 30% of the posts are with an exposure level of silica dust, coal dust, and noise that exceeds the standard. The exceedance rate and the median of the time-weighted average concentration of total coal dust among large and medium-sized enterprises are higher than those among small and micro-sized enterprises (P<0.05) . Conclusion: The dust and noise hazards in the mining industry are lower than in the past in China, but more than 25% of workers are still at a high risk of occupational pneumoconiosis and noise deafness. Therefore, intervention and surveillance strategies should be strengthened in the future.

To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

Objective: To understand the core knowledge level and influencing factors of chronic disease prevention and control in Adults in China, and to provide a scientific basis for formulating chronic disease prevention and control measures. Methods: In this study, cross-sectional survey and quota sampling were used to recruit 173 819 permanent residents aged 18 and above from 302 counties of adult chronic diseases and nutrition surveillance in China to conduct an online questionnaire survey, including basic information and core knowledge of chronic diseases. The scores of the core knowledge of chronic disease prevention and control were described by median and interquartile range, the Wilcoxon rank sum test or the Kruskal Wallis test was used for the inter-group comparison, and the correlation factors of the total score were analyzed by the multilinear regression model. Results: A total of 172 808 participants were surveyed in 302 counties and districts, of which 42.60%(73 623) were male and 57.40%(99 185) were female; The proportion of respondents aged 18-44, 45-59, and 60 years old and above was 54.74% (94 594), 30.91% (53 423) and 14.35% (24 791), respectively. The total score of the core knowledge of chronic prevention and control in the total population was 66(13), and the scores of different characteristic groups were different, and the differences were statistically significant: the eastern region had the highest score at 67(11) (H=840.66, P<0.01), the urban 66(12) was higher than the rural 65(14) (Z=-31.35, P<0.01), and the male 66(14) was lower than female 66(12) (Z=-11.66, P<0.01), 18-24 years old 64(13) was lower than other age groups(H=115.80, P<0.01), and undergraduate degree and above had the highest score compared to other academic qualifications, with 68(9) points(H=2 547.25, P<0.01). Multivariate analysis showed that eastern (t=27.42, P<0.01), central (t=17.33, P<0.01), urban (t=5.69, P<0.01), female (t=17.81, P<0.01), high age (t=46.04, P<0.01) and high education (t=57.77, P<0.01) had higher scores of core knowledge of chronic disease prevention and control than other groups, the scores of core knowledge of chronic disease prevention and control of professional and technical personnel (t=8.63, P<0.01), state enterprises and institutions (t=38.67, P<0.01), agriculture, forestry, animal husbandry, fishery and water conservancy production (t=5.30, P<0.01), production, transportation and commercial personnel (t=24.87, P<0.01), and other workers (t=8.89, P<0.01) were higher than those of non-employed people. Conclusion: There are differences in the total scores of the core knowledge of chronic disease prevention and control in different characteristics of people in China, and in the future, health education on the prevention and treatment of chronic diseases should be strengthened for specific groups to improve the knowledge level of residents.
