The survey on the hesitant status of rubella-containing vaccine (RCV) vaccination was conducted among 2 141 women of childbearing age in four provinces, Liaoning, Jiangsu, Zhejiang, and Anhui, from May 2017 to March 2018. Among the 2 141 study participants, a total of 38.21% (818) of women of childbearing age were aware of rubella and 21.25% (455) of women of childbearing age knew about RCV. Among the 455 women of childbearing age who were aware of RCV, 262 (57.58%) were willing to be vaccinated with RCV; 304 women of childbearing age (66.81%) tended to be vaccinated with RCV free of charge. Among the 193 women of childbearing age who did not want to be vaccinated or did not decide whether they preferred to be vaccinated with RCV, no one around them was vaccinated (89, 46.11%) and fear of vaccine safety (70, 36.27%) were the main reasons for hesitation to receive RCV.

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95％CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95％CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95％CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95％CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95％CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95％CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95％CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Platelet-derived growth factor receptor beta (PDGFRB) rearrangements play an important role in the pathogenesis of eosinophilia-associated myeloid/lymphoid neoplasms. Up to now, more than 70 PDGFRB fusions have been identified. Here, a novel PDGFRB fusion gene CSNK2A1-PDGFRB has been identified in myeloproliferative neoplasm (MPN) with eosinophilia by RNA-sequencing, which has been verified by reverse transcription polymerase chain reaction and Sanger sequencing. The new PDGFRB fusion partner gene CSNK2A1 encoded one of the two catalytic subunit of casein kinase II (CK2). To our knowledge, this is the first report on the involvement of CSNK2A1 in fusion genes, especially fusion with another kinase PDGFRB in MPN. In addition, the CSNK2A1-PDGFRB fusion retained the entire kinase domain of PDGFRB and response to imatinib at low concentration. The patient with CSNK2A1-PDGFRB was sensitive to imatinib treatment and acquired sustained complete remission.

Objective To investigate the clinical manifestations and imaging features of isolated cortical vein thrombosis (ICoVT).Methods The data of patients with ICoVT admitted and treated in Shengjing Hospital of China Medical University from 2005 to 2015 were collected.Their clinical manifestations and imaging features were analyzed.Results A total of 104 patients with cerebral venous sinus thrombosis were enrolled.Seven (6.7％) of them with ICoVT were enrolled in the analysis.There were 6 women (85.7％).Their average age was 35 years (range 25-46 years).Headache (n =6;85.7％),seizures (n=5;71.4％),and limb paralysis and numbness (n =4;57.1％) were the most common clinical manifestations.All patients underwent head CT,MRI,and magnetic resonance venography (MRV).Focal cerebral tissue edema (n =5;71.4％) and hemorrhagic infarction (n =3;42.9％) were the most common imaging features.Susceptibility weighted imaging of 3 cases revealed cord-like hypointensity,indicating the formation of venous thrombosis.The clinical symptoms of all patients were relieved after anticoagulant therapy.They were followed up for 1.5 years and no recurrence was observed.Conclusion Headache and seizures are the most common clinical symptoms of IcoVT.Imaging is mostly manifested as focal cerebral edema or hemorrhagic infarction.

Objective To investigate the evaluation index of melasma staging by clinical manifestations and non-invasive skin detection technology.Methods A total of 195 patients with a clinical diagnosis of melasma were enrolled from the First Affiliated Hospital of Kunming Medical University.The skin with lesion enlarged,color darker,erythema,red occured after scratching or lesion faded after compressing with glass belonged to the active stage;on the contrary,it was in the stable stage.Reflectance confocal microscopy (RCM),dermoscopy,Mexameter 18 and LAB were used to observe skin lesions of different stage of melasma.Results There were 115 patients (59.0 ％) in the active stage of melasma and 80 patients (41.0 ％) in the stable stage.DMA score in active stage 35.08± 10.59 were significantly higher than that of the stable stage 15.06-4-9.20 (P＜0.05).There were statistically significant difference in the quantity of inflammatory cell and blood vessels between two stages of melasma (P＜0.05).Erythema index (EI) in active stage of melasma 376.35±61.39 were high-er than that of the stable stage 320.364± 62.40 (P＜0.05).A-value in active stage of melasma 13.28± 1.75 were higher than that of the stable stage 12.34± 1.78 (P＜0.05).However,there were no siginificant differences in the quantity of melenin,melanin index (MI),L-value and B-value.Conclusions Melasma could be divided into active stage or stable stage,respectively,according to its clinical manifestations.DMA score,quantity of inflammatory cells and blood vessels,EI and A-value could be used as the reference index of melasma staging.

OBJECTIVE:To conduct the quality assessment of artificial Aquilaria sinensis by"cutting inducing technique", and provide reference for its scientific planting and harvest. METHODS:GC-MC and HPLC were adopted to detect the volatile in-gredients,characteristic spectrum,incense tetraol and alcohol-soluble extract contents in 3 batches of artificial A. sinensis(Num. 1, 2,3,respectively for 5,10,20 years)by"cutting inducing technique". RESULTS:The volatile ingredients of 3 batches of artifi-cial A. sinensis mainly consisted of aromatic compounds,sesquiterpene compounds,fatty acid compounds and chromone com-pounds. The characteristic spectrums of samples 2,3 were basically the same with the reference substance of A. sinensis. The in-cense tetraol contents of 3 batches of samples were 0.078%-0.254%,and alcohol-soluble extract contents were 12.4%-20.8%. The characteristic spectrum and the incense tetraol content of sample 1 were not conformed to the standards in Chinese Pharmacopoeia (2015 edition,part 1). CONCLUSIONS:Artificial A. sinensis by"cutting inducing technique"shows similar volatile ingredients to natural A. sinensis. The quality of artificial A. sinensis for more than 10 years is conformed to the standards in Chinese Pharmaco-poeia(2015 edition,part 1),which can be used as medicine,replacing the natural A. sinensis.

Objective To investigate whether autophagy can be induced by 1,4-benzoquinone (1,4BQ) in HL60 cells,as well as the role of reactive oxygen species (ROS)in induced autophagy.Methods In order to determine a suitable 1,4-BQ treatment concentration for autophagy detection in HL60 cells,the cell vitality were examined by CCK8 assay.Logarithmic-growth-phased cells were divided into control group,1,4-BQgroup(10μmol/L 1,4-BQ,24 h),NAC group (antioxidant n-acetyl cysteine,5mmol/L,24 h) and the 1,4-BQ+NAC group (5 mmol/L NAC were preincubated for 1h prior to the treatment with 10 μmol/L 1,4-BQ for 24 h).The autophagic acidic vesicle were inspected by acridine orange staining,LC3 were detected by immunofluorescence staining,and expressions of LC3 and Beclin1 were quantitatively detected by Western blot.Results The results from cell viability test indicated that 1,4-BQ exhibited a dose-dependent toxicity to HL60cells.Compared with control group.the cell viability in 20.0、40.0μmol/L concentration were decreased obviously,and the differences had statistical significance (P＜0.05).Compare with contrd group acidic vesicle,LC3II,LC3II/LC3I and Beclin1 protein expressions were increased in 1,4-BQ group,after both respectively 12.4％ and 27％,the differences had statistital significance.While 1,4-BQ+NAC group was observed that acidic vesicle,LC3 and Beclin1 protein level were markedly lower than 1,4-BQ group,after both decreased 12.6％ and 22.6％ respectively,both the difference were statistically significant (P＜0.05).Conclusion 1,4-BQ can induce autophagy in HL60 cells,the induction of autophagy is at least partly resulted from ROS.Antioxidant can effectively suppress the occurrence of induced autophagy.
