Objective To explore the relationship between the ET-1 and the oncogenesis, development of human esophageal cancer. Methods RT-PCR and Western blotting were employed to detect the expression of ET-1 and ETAR in the tissues of esophageal cancer and normal esophageal mucous membrane from 76 esophageal cancer patients admitted by our hospital from March to December in 2002. Results There was positive ET-1 mRNA expression in 82.7% (62/75) of the specimens of esophageal cancer and in 60% (45/75) of normal tissue and the ET-1 mRNA expression had a relation with histological grade, lymph node metastasis and clinical staging of esophageal cancer (P

The clinical and laboratory data of a patient with chronic refractory immune thrombocytopenia (ITP) who had a significant increase in the proportion of inhibitory T cells in the hematological oncology center of Beijing Children′s Hospital Affiliated to Capital Medical University in February 2018 and regularly followed up in the outpatient department received a retrospective analysis.This 8-year-old patient′s clinical features were 6 years of skin and mucous membrane bleeding spots and petechiae recurring, with occasionally nasal epistaxis.Physical examination: cardiopulmonary abdomen and nervous system examinations are normal, and no superficial lymphadenopathy is touched.Blood routine indicated that the platelets were 2.00×10 9/L, and white blood cell count and hemoglobin level were normal.Bone marrow suggested that hyperplasia was significantly active, with more than 300 megakaryocytes.The patient was diagnosed with ITP, and he was treated with first-line treatment with gamma globulin and oral Corticosteroids.The first-line treatment with high-dose Dexamethasone therapy was repeated, and the second-line treatment was low-dose Rituximab combined with high-dose Dexamethasone.Evaluations had been conducted with every relapsed course, and Cyclosporine was administered orally on the basis of the highly suppressive T cells.After half a month, the child achieved partial remission and continued for 3 months, and then reached a complete remission of 6 months (till this paper). It is suggested that, with ITP as an immunological disease with high heterogeneity, the immune abnormality index is expected to become a breakthrough in the development of precise treatment.

Objective To understand the current situation and relevant factors on sexual violence in 18-34 year-olds men in Chengdu,in order to provide data for setting up prevention and reduction programs on sexual violence and other related problems.Methods By multi-stage random sampling,young men who were 18-34 years old in Chengdu were interviewed and screened.Questionnaire and multivariate logistic regression models were used to assess risk factors on sexual violence.Results The overall prevalence of sexual violence was 17.8%,with factors as child exposure to parent violence/family conflict (P<0.01),child physical abuse (P<0.01),alcohol abuse (P<0.01),anxiety (P<0.01),disharmony marriage (divorce/ widowed/separation) (P<0.01),marriage status (P<0.05),depression (P<0.05) as risk factors of sexual violence.Conclusion The status on sexual violence among young men in Chengdu should not be overlooked and interventions for high-risk populations should be taken urqently.

Objective:
To study the expression and distribution of filaggrin (FLG) in oral submucous fibrosis (OSF) and to explore the significance of FLG in the occurrence and development of OSF.
Methods :
Ten cases with a normal oral mucosa (normal buccal mucosa group) and 30 cases of tissues with OSF lesions, including 10 cases each in the early (early OSF group), moderate (middle OSF group) and advanced stages (late OSF group), were selected. FLG was analyzed by immunohistochemistry. The FLG-positive cells were counted to calculate the percentages of cells with FLG-positive expression in each group.
Results:
FLG expression was negative in most of the normal buccal mucosa group specimens and was positive in the OSF buccal mucosal epithelial specimens. With aggravation of the OSF lesion, the number of FLG-positive cells increased. In the early OSF group, FLG-positive expression was mainly concentrated in the granular and keratinized epithelial layers. In the middle OSF group, the number of FLG-positive epithelial cells increased gradually. In the late OSF group, almost all epithelial cells were FLG-positive in the cytoplasmic nucleus. The percentages of FLG-positive cells in the early, middle and late OSF groups were (24.63 ± 9.06)%, (54.23 ± 10.63)% and (83.97 ± 8.72)%, respectively. The percentage of FLG-positive cells was significantly higher in the OSF group than in the normal mucosa group (P < 0.05).
Conclusion
FLG was expressed at a higher level in the OSF epithelium than in the normal oral mucosal epithelium and was upregulated in the OSF epithelium with aggravation of the OSF lesions. Abnormal FLG expression may be related to the terminal differentiation disorder of OSF epithelial keratinocytes.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.
