Anti-Sj?gren's syndrome type A（SSA) and anti-Sj?gren's syndrome type B（SSB) antibodies both belong to the antinuclear antibody spectrum and are common in patients with systemic lupus erythematosus, Sj?gren's syndrome and undifferentiated connective tissue disease as well as asymptomatic patients. Approximately 1% of pregnant women are positive for anti-SSA and anti-SSB antibodies and only 1%-3% of the fetuses carried by primiparae with anti-SSA and anti-SSB antibodies show immune-mediated cardiac conduction and structural abnormalities. Due to its low incidence and insidious onset, some pregnant women were diagnosed positive for antibodies against SSA and SSB for the first time only due to fetal heart block or structural abnormalities during pregnancy. Domestic and international research on the effects of anti-SSA and anti-SSB antibodies on fetal heart and the prenatal monitoring, diagnosis, intrauterine treatment and prognosis of fetal cardiac abnormalities related to anti-SSA and anti-SSB exposure are reviewed to guide the clinical work of obstetrics.

Objective:To investigate the clinical features of IgD multiple myeloma (MM) and the effect and prognosis of daratumumab-based combination therapy.Methods:The clinicopathological data of a IgD MM patient with disease progression and extramedullary infiltration treated with daratumumab in the Affiliated Hospital of Qingdao University in December 2019 were retrospectively analyzed.Results:The 74-year-old woman was diagnosed as IgD MM by bone marrow aspiration and immunofixation electrophoresis. The patient was given VD (bortezomib, dexamethasone), RD (lenalidomide, dexamethasone) and ID (ixazomib, dexamethasone) regimens. In June 2020, the patient developed multiple subcutaneous nodules, and she was assessed as progressive disease with extensive extramedullary infiltration. After treated with daratumumab-PAD (liposomal doxorubicin, bortezomib, dexamethasone) regimen, the patient's subcutaneous nodules were significantly reduced and partially disappeared, and the general condition was significantly improved. But the patient was in a cachexia state and finally died of the irregular treatment and disease progression.Conclusions:IgD MM has a low incidence and a short survival period, and there is no uniform standard treatment. The early application of daratumumab combined with proteasome inhibitors, immunomodulators, cytotoxic drugs and hematopoietic stem cell transplantation may improve the overall survival of patients.

Objective: This study aims to investigate the willingness and influencing factors of COVID-19 vaccination among Chinese middle school students, and to provide a reference for promoting the implementation of COVID-19 vaccination among middle school students. Methods: An online survey was conducted among middle school students in Beijing, Anqing of Anhui Province, Xi an of Shaanxi Province and Shenzhen of Guangdong Province, and 9 153 participants were enrolled in the present study. Single factor analysis and multinomial Logistic regression was used to determine the related factors of COVID-19 vaccination willingness. Results: The prevalence of vaccine acceptance, vaccine hesitancy and vaccine refusal among middle school students were 60.05%, 31.59% and 8.36%, respectively. The results of Chi square analysis showed there were significant difference of COVID-19 vaccination willingness among sex, school residence, grade, region, vaccination willingness of surrounding classmates, vaccination willingness of others, fear of SARS-CoV-2 and risk of SARS-CoV-2 infection( χ 2=8.43-1 059.43, P <0.05). Multinomial Logistic regression analysis presented that, compared to "vaccine acceptance" group, those girls, non resident in school, living in Beijing or Anqing, disagree or uncertain with influenced by peers, disagree or uncertain with influenced by others, uncertain with fear of SARS-CoV-2, disagree or uncertain with having risk of SARS-CoV-2 infection were more likely to show vaccine hesitancy( OR =1.22,1.21,1.49,1.69,1.75,2.54,1.41,2.32,3.32,1.99,2.38, P <0.05). And those non boarding in school, living in Beijing or Xi an, disagree or uncertainty influenced by peers, disagree or uncertainty influenced by others, disagree with fear of SARS- CoV- 2, disagree or uncertainty in having risk of SARS-CoV-2 infection were more likely to show vaccine refusal ( OR =1.27, 2.29 ,1.46,3.88,2.37,2.31,1.47,2.14,4.24,1.47, P <0.05). Conclusion The willingness of COVID-19 vaccination among middle school students in four cities is low, and targeted interventions should be advocated to form herd immunity.

Objective: To explore the longitudinal association between organophosphate esters (OPEs) exposure and blood pressure in children, so as to provide a reference for identifying the effects of OPEs exposure on child health. Methods: A total of 404 children from the Beijing Child Growth and Health Cohort (PROC) were enrolled using a case cohort study design, baseline physical examination, urine collection, questionnaires survey were administered in 2018 and follow up surveys in 2019-2020 and 2023. Participants were divided into case group ( n =140) and control group ( n =264) according to the observation of new onset of high blood pressure during the follow up period. High performance liquid chromatography tandem mass spectrometry was used to detect diethyl phosphate (DEP)，bis (2-chloroethyl) phosphate (BCEP)，bis (1-chloro-2-propyl) phosphate, (BCIPP), diphenyl phosphate(DPHP), dibutyl phosphate (DnBP), bis (1,3-dichloro-2-propyl) phosphate(BDCIPP), bis(2-butoxyethyl) phosphate(BBOEP), bis (2-butoxyethyl) 2-hydroxyethyl phosphate (BBOEHEP), 4-hydroxyphenyl diphenyl phosphate (4-OH-TPHP). Generalized linear mixed models and Quantile g computation models were developed to analyze the longitudinal associations between OPEs individual/mixed exposure and blood pressure in children. Results: The detection range of 9 OPEs metabolites,including DEP, BCEP, BCIPP, DPHP, DnBP, BDCIPP, BBOEP, BBOEHEP and 4-OH-TPHP at three time points (baseline, first follow up and second follow up) were 27.7%-92.1%, 24.0%-99.3% and 39.2%-90.9% respectively. Without adjustment for covariates such as gender, age, body mass index, Tanner stage, parental education, and monthly household income, and family history of hypertension, the increase of BDCIPP concentration and mixed exposure of OPEs may reduce children s systolic blood pressure( β= -0.85，-2.40，95%CI=-1.69--0.01，-3.30--1.50，P <0.05). After adjusting for the covariates, the longitudinal association of individual OPEs or mixed exposure with pediatric BP was not statistically significant ( P >0.05). Conclusion Children are commonly exposed to OPEs, and although no significant longitudinal associations are observed between exposure to OPEs and blood pressure among school aged children in Beijing, it is recommended that child exposure should be minimized whenever possible.

Objective: To explore sex difference in the cardiovascular health (CVH) status of 6-8 year old children in Beijing, so as to inform the early intervention of CVH related lifestyles. Methods: Based on the Beijing Children s Growth and Health Cohort (PROC), baseline physical examination, sequential questionnaire survey, and laboratory tests were conducted among 1 914 grade 1 students. Children s CVH and its subscales (health behaviors and health factors) scores were calculated according to the Life s Essential 8 (LE 8) index and categorized into high, moderate, and low CVH. CVH scores were reported as medians and interquartile ranges; sex differences were compared using the Chi square test and Wilcoxon test. Results: Among the 1 914 participants, the percentages of high, moderate, and low CVH were 35.7%, 63.5%, and 0.8%, respectively, and the percentages of high, moderate, and low health behavior scores were 25.9%, 67.5%, and 6.6%, respectively, with no statistically significant differences between sex ( χ 2=2.30, 0.07, P >0.05). The rates of high, moderate, and low health factor scores for boys and girls were 61.1%, 36.0%, 2.9% and 71.1%, 28.4%, 0.5%, respectively, with a statistically significant sex difference ( χ 2=31.88, P < 0.01). The overall CVH score was 76.0(70.0, 83.0), 76.0(69.0, 82.0) for boys, and 77.0(71.0, 83.0) for girls. Among the health behavior metrics, sleep scores were the best and physical activity scores were the worst[100.0(90.0,100.0), 40.0(20.0, 80.0 )]; among the health factor metrics, blood glucose scores were the best and lipid scores were the worst[100.0(100.0,100.0), 60.0(40.0,100.0)]. In respect to health factors, there were significant gender differences in body mass index, blood lipids, blood sugar, and blood pressure scores ( Z =-6.92, 3.01, -6.60, -2.30, <0.05), but there were no significant gender differences in diet, physical activity, nicotine exposure, or sleep scores with regards to health behaviors ( Z =0.99, 0.88, -0.13, 0.36, P > 0.05 ). Compared to boys, girls in the low and moderate CVH groups had high health factor scores despite low health behavior scores. Conclusion Most 6 to 8-year-old children in Beijing were found to have relatively good CVH, and optimization of children s CVH status can be achieved by promoting healthier lifestyles and monitoring health factors, especially among boys.

As the guiding theory for the diagnosis and treatment of encephalopathy in traditional Chinese medicine （TCM）， The marrow sea theory has important theoretical connotation and clinical value. This paper summarized the clinical research literature on the differentiation and treatment of common encephalopathy based on the marrow sea theory published in recent years， analyzed the treatment method and effects from eight aspects in terms of stroke， dizziness， insomnia， headache， constraint syndrome， dementia， tremor syndrome， and atrophy syndrome， and discussed the possible mechanism based on the relevant basic research. It is believed that marrow sea depletion is the common pathogenesis of encephalopathy in TCM. Guided by the method of supplementing essence and boosting marrow， the corresponding formulas and medicinals are recommended in accordance with differentiated syndromes， which can effectively improve the symptoms of the disease， delay the progression， increase the daily life ability of the patients， and improve the quality of life. Based on the marrow sea theory， the method of supplementing essence and boosting marrow， rectifying healthy qi and dispelling pathogen can be used to highlight the advantages of TCM and provide ideas for the diagnosis and treatment of encephalopathy in TCM.

ObjectiveTo summarize the thinking of treatment of headache based on syndrome differentiation by reviewing the literature of materia medica in the past dynasties， so as to guide the clinical practice. MethodAll the literature of materia medica in the Chinese Medical Dictionary， involving 76 works from Han to Qing Dynasties， were searched， and the information of the herbs for treating headache was extracted. According to Chinese Materia Medica （11th Edition） and Pharmacopoeia of the People's Republic of China （2020 Edition）， the nature， taste， and meridian tropism of the selected herbs were statistically analyzed， and the syndrome elements of headache were classified and counted. In addition， the contents of syndrome differentiation and treatment of headache by different herbs were extracted. ResultFrom the 76 monographs of materia medica in the past dynasties， 114 herbs for treating headache were selected. The herbs mainly had cold or warm nature， pungent or bitter taste， and tropism to the lung and live meridians. The syndrome elements of headache treated by the herbs mainly included wind attack， fire disturbance， turbid obstruction， stagnation， cold coagulation， and healthy Qi deficiency. ConclusionHeadache is mainly treated with the herbs with the effects of dispelling pathogenic wind， clearing heat and purging fire， eliminating phlegm and resolving dampness， regulating Qi movement and activating blood， warming Yang and dispelling cold， and tonifying deficiency and reinforcing healthy Qi， and the herbs are often used in combinations. Headache is treated following the principles of dispelling wind and pathogen， regulating Qi and blood， and tonifying deficiency and purging excess， which is in line with the laws of obstruction and nutrient deficiency causing pain.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

OBJECTIVE: To analyze the effect of occupational stress on abnormity of serum total cholesterol and triglyceride in male steel workers. METHODS: A total of 3 957 male steel workers from an iron and steel group company were selected as study objects by judgment sampling method. Occupational stress was measured by the Chinese version of Job Content Questionnaire. The serum total cholesterol and triglyceride levels were measured using fasting venous blood. RESULTS: Among the 3 957 workers,the detection rate of occupational stress was 56. 8%,and 55. 0% of them showed high social support. The abnormal rates of total cholesterol and triglyceride were 21. 8% and 40. 9%,respectively. The multivariate logistic regression analysis showed that workers with high social support had high risk of abnormal total cholesterol and abnormal triglyceride than workers with low social support( P < 0. 05) after adjusting for confounding factors such as age,education level,marital status,body mass index,smoking and drinking alcohol,tea. The odds ratio of abnormal total cholesterol in occupational stress workers was 1. 17 times of that of non-occupational stress workers. No association was found between occupational stress and abnormal triglyceride( P > 0. 05). CONCLUSION: Occupational stress may be associated with abnormity of total cholesterol in male steel workers. Social support is an important influences factor to the abnormity of total cholesterol and triglyceride in male steel workers.
