Objective To investigate characteristic skin lesions and typical histopathological changes of adult-onset Still's disease(AOSD) for its early diagnosis and treatment.Methods Clinical data were collected from 8 patients with AOSD,and analyzed retrospectively.Results All the patients had transient rashes and persistent papules/plaques during the course of disease.Of the 8 patients,1 had urticaria-like rashes,3 had dermatomyositis-like rashes,and 1 had prurigo pigmentosa-like rashes.Biopsies were carried out at the sites where transient rashes or persistent papules/plaques occurred.Histopathological findings showed necrotic keratinocytes in the upper prickle cell layer,and perivascular infiltration of neutrophils and lymphocytes in the upper dermis.Conclusion The skin lesions and histopathological changes of AOSD are characteristic,which can provide clues to the early diagnosis of AOSD.

Aim To evaluate the mechanism of apopto-sis induced by the isoliquiritigenin in A375 human ma-lignant melanoma cells. Methods Sulforhodamine B ( SRB) method was used to determine the A375 cell viability;acridine orange/ethidium bromide ( AO/EB) and Hoechst 33258 staining were used to observe the morphological changes of apoptotic cells; flow cytome-try was used to detect A375 cell apoptotic rate;DCFH-DA was applied to determine the changes of total intra-cellular ROS in A375 cells;JC-1 method was used to measure the changes of mitochondrial membrane poten-tial;the kits methods were used to determine the con-tent of ATP, lactic acid and glucose in A375 cell which was treated with different concentrations of isoliquiritigenin. Results Isoliquiritigenin could in-hibit A375 cell proliferation in a concentration-depend-ent manner; A375 cells showed obvious apoptosis charateristics after treatment by isoliquiritigenin, and the apoptosis rate increased with increasing concentra-tion of isoliquiritigenin. The level of total intracellular ROS in A375 cells increased obviously after dealing with different concentrations of isoliquiritigenin;in ad-dition, the mitochondrial membrane potential, the lev-els of intracellular ATP,lactic acid and the level of glu-cose uptake all declined. Conclusions These find-ings demonstrate that isoliquiritigenin can induce apop-tosis of A375 cells. The mechanism may be related to elevation of ROS level and reduction of aerobic glycoly-sis level.

Aim To investigate the mechanism of the melanoma B16 F10 cells proliferation induced by Lico-chalcone A in vitro. Methods The proliferation of B16 F10 cells induced by Licochalcone A was deter-mined by SRB method. The morphological changes were observed using Giemsa staining under the phase contrast microscope equipped with a digital camera. The melanin level was assessed by colorimetric meth-od. The apoptotic rate was determined by Annexin V-FITC/PI assay. Cell cycle distribution was determined by flow cytometry. The mRNA expression levels of B cell lymphoma/lewkmia-2 ( Bcl-2 ) , Bcl-2 associated X protein ( Bax) , the cell cycle protein CyclinE2 and cyclin-dependent kinase-2 ( CDK2 ) CDK2 were detec-ted using Q-PCR analysis. Results The proliferation of B16 F10 cells treated with Licochalcone A was effec-tively inhibited in a concentration and time-dependent manner. A clear morphological change was observed with the increasing concentration of Licochalcone A in B16F10 cells, the dendrite-like projections changed to the narrowing ball shape, which was associated with the increasing melanin level. The low concentration of Licochalcone A could induce B16F10 differentiation, and the high concentration of Licochalcone A could in-duce B16F10 apoptosis, which was accompanied with the increasing G1 phase in cell cycle. The mRNA ex-pression levels of Bcl-2 /Bax, CyclinE2 and CDK2 were markedly reduced. Conclusion Licochalcone A can effectively inhibit the proliferation of B16 F10 cells, induced cell cycle arrest at G1 phase, and fur-ther induced differentiation and apoptosis.

Andrographolide total ester sulfonate (ATES) injection is one of the products of traditional Chinese medicine (TCM) currently used against viral infection in China.ATES injection was approved for manufacturing and marketing in January 2002.It is indicated for acute respiratory infections,tonsillitis,chronic obstructive pulmonary disease,influenza,foot and mouth disease,bronchiolitis,herpangina,mumps,infectious mononucleosis and psychosis.However,its usage also carries risk.We investigated the use of ATES at the Wuhan Union Hospital from January 2014 to December 2014 and evaluated its real-word clinical application using the hospital centralized monitoring method.A total of 848 cases were enrolled in this study.In these cases,it was mainly used for postoperative anti-inflammation and treating upper respiratory infection,pneumonia and bronchitis.Among them,39.86％ were contraindicated.Irregular medication of adults and children accounted for 1.91％ and 23.38％,respectively.Improper choice of solvent accounted for 3.18％.The choice of intravenous drip versus aerosol inhalation was reasonable.A case of adverse events (AEs) was observed in the monitoring period,and the incidence of adverse drug reaction (ADR) of ATES injection was 0.12％.ATES injection in our hospital is relatively safe with a low incidence of adverse reactions.The study assesses the clinical usage and adverse reactions of ATES injection,and provides suggestions for rational use in clinical practice.

OBJECTIVE: To compare the vertigo controlling situation between the endolymphatic sac decompression(ELSD) and semicircular canal occlusion (SCO) in stage 4 Ménière disease. METHOD: Fourteen patients who underwent endolymphatic sac decompression and 9 patients who underwent semicircular canal occlusion from 2009 to 2013 were followed. All patients has complete preoperative examination and postoperative follow-up. RESULT: The vetigo control of the patients underwent endolymphatic sac decompression: completely control 35.7%; basic control 28.6%; partly control 14.3%; the vetigo control of the patients underwent semicircular canal occlusion: completely control 88.9%; basic control 11.1%. CONCLUSION ELSD and SCO are alternative methods for the patients of stage 4. SCO has a much highter complete vertigo control rate. For the patients without practical listening, SCO is a better choice.

Objective: To understand the incidence of school bullying and its influencing factors among adolescents in low-income and middle-income countries, and to explore the association between school bullying and mental health of adolescent students, so as to provide reference for prevention and control of school bullying and mental health intervention. Methods: Data was obtained from the 2009-2015 Global School Student Health Survey from 19 low-income and middle-income countries (n=22 963). Binary Logistic regression was used to analyze the influencing factors of school bullying, and multiple linear regression was used to analyze the relationship between school bullying and mental health. Results: The average score of students mental health was(5.75±2.09), and approximately 35.1% of adolescent students reported suffering from school bullying. The rates of school bullying among students in low-income and middle-income countries were 39.4% amd 34.3%, respectively. Students with lower grades, overweight, poor family economic status, low family learning and psychological support, poor perceived family relationship, more truancy, and poor relationship with classmates were more likely to suffer from school bullying(P<0.05). Exposure to school bullying was positively associated with adverse mental health outcomes for women(B=1.27, P<0.01). Conclusion Not only were school bullying more common in low-income countries, but also school bullying had a greater negative impact on the mental health of girls. We need to pay more attention to school bullying among adolescent students, especially in low-income countries and girls, with cost-effective interventions to reduce or mitigate the consequences of bullying.

OBJECTIVETo investigate the expression of long non-coding RNA HOTAIR in the plasma of breast cancer patients and its value in the diagnosis of breast cancer.

METHODSHOTAIR levels were measured in 24 tumor tissues and 70 plasma samples from breast cancer patients using quantitative real-time PCR. The correlations of plasma HOTAIR level with the clinicopathological features of the patients were analyzed. A multivariate logistic regression model was established to analyze the value of plasma HOTAIR in comparison with plasma CA153 and CEA levels for breast cancer diagnosis. We further detected HOTAIR levels in the plasma and breast cancer tissues of 24 patients before and after operation and investigated their correlation.

RESULTSBreast cancer patients had increased expressions of HOTAIR in the tumor tissues and plasma, and plasma HOTAIR level was significantly correlated with estrogen receptor (ER) level (P=0.004) and lymph node metastasis (P=0.010). Receiver operating characteristic (ROC) curve and the multivariable logistic regression model showed that the area under ROC curve (AUC) of plasma HOTAIR was 0.82 (P<0.001) for breast cancer diagnosis with a diagnostic sensitivity and a specificity of 73.3% and 93.3%, respectively. The diagnostic power and specificity of plasma HOTAIR was much higher than those of CA153 (AUC=0.66, P=0.030) and CEA (AUC=0.52, P=0.001), and the combination of the 3 markers further enhanced the diagnostic power (AUC=0.84) and specificity (96.7%). Plasma HOTAIR level was significantly reduced in the patients after the operation (P<0.0001) and showed a moderate correlation with its expression in tumor tissues (r=0.62, P<0.0001).

CONCLUSIONPlasma HOTAIR may serve as a potential biomarker for breast cancer diagnosis.
