Objective: To explore the prevalence and co-morbidity in depression disorder among children and adolescents in Chengdu City. Methods: Using a one-phase design, 4S8S children and adolescents in grades 1～10 were assessed with the Strength and Difficulty questionnaire (SDQ) and Development and Well-Being Assessment (DAWBA) . A structured interview with verbatim reports was reviewed by clinicians so that information from parents, teachers, and children were combined in a manner that emulated the clinical process. Results: (1) The rate of depressive disorder was 1.2% , and that in girls was much higher than that in boys after 12 years old (2.56% vs. 1.42%) . (2) The rate of depressive disorder increased with age from 0.10% (6～8 years) to 2.59% (≥ 15 years) . (3) The co-morbidity was 40% . The most common comorbidity diagnosis was anxiety disorders (29.1%) and behavior disorders (25.5%) . Conclusion: The prevalence of depressive disorder among children and adolescents in Chengdu is 1.2%. Gender and age may be the related factors. The co-morbidity is common in children and adolescents with depression disorder.

Objective To analyze the differences with the expression of glucocorticoids receptor isoforms ( GRα, GRβ, GRγand GR-P ) and cytokines [ IL-6, macrophage migration inhibitory factor (MIF), IFN-γand IL-10] between patients with systemic lupus erythematosus (SLE) and rheumatoid ar-thritis ( RA) , and to further understand their correlations with disease activities.Methods Fifty-five pa-tients with SLE, forty-nine patients with RA and thirty-eight healthy subjects were recruited in this study. All patients were steroid-naive.The expression of GRα, GRβ, GRγ, and GR-P in peripheral blood mononu-clear cells at transcript levels were determined by real-time PCR.Enzyme-linked immunosorbent assay was used to detect the expression of IL-6, MIF, IFN-γand IL-10 in serum samples.Results The percentages of GRαin all subjects were the highest among four isoforms of GR, followed by GR-P, GRγand GRβ.Com-pared with healthy subjects, patients with SLE or RA showed significantly decreased expression of GRα( P<0.05), but increased expression of GR-P (P<0.05).The percentages of GR-P in patients with RA were higher than those in patients with SLE (P<0.05).The expression of GRαwas negatively correlated with SLE disease activity index (SLEDAI) and disease activity score 28 (DAS28).SLE or RA patients with high disease activity showed lower expression of GRαthan those with low disease activity.The levels of IL-6, IFN-γand MIF in patients with SLE or RA were significantly higher than those in healthy subjects ( P<0.05).A negative correlation was observed between the expression of IL-6 and GRαin patients with SLE (P<0.05).The expression of IFN-γwas negatively correlated with GRαin patients with RA (P<0.05). Conclusion There were significant differences with the expression of GR isoforms among patients with SLE, patients with RA and healthy subjects, indicating the change of internal environment in patients might be in-volved in GR alternative splicing.GRαwas the predominant isoform and was negatively correlated with dis-ease activities.Oversecretion of cytokines resulted in a decreased expression of GRα.This study would be useful for the diagnosis of the disease status and for monitoring clinical treatment.

Objective To investigate the expression and significance of syntaxin 8 (STX8) in non-small cell lung cancer (NSCLC),and analyze the relationship between STX8 expression and clinicopathological features of NSCLC.Methods Seventy samples of NSCLC and 70 samples of pericancerous tissues were collected for immunohistochemistry staining,and another 10 samples of NSCLC and pericancerous tissues were used for RNA and protein extraction,qRT-PCR was performed to detect the expression of STX8 mRNA,and Western blot assay was adopted to detect the expression of STX8 protein.The relationship between STX8 expression and clinicopathological features of NSCLC was analyzed.Results Results of qRT-PCR showed that the expression of STX8 mRNA was significantly higher in NSCLC tissues than that in the pericancerous tissues (3.962 5±0.487 3 vs.0.538 2±0.097 5,t=21.797,P＜0.01).Immunohistochemistry results showed that the high expression rate of STX8 was significantly higher in NSCLC tissues than that in the pericancerous tissues [71.43％ (50/70) vs.38.57％ (27/70),x2=15.267,P＜0.01].Western blot results showed that the expression of STX8 protein was significantly higher in NSCLC tissues than that in the pericancerous tissues (2.496 1±0.362 5 vs.0.340 2±0.119 1,t=17.876,P＜0.01).The high expression rate of STX8 was significantly different in different histological types of NSCLC (P ＜0.05).The high expression rate of STX8 was higher in squamous cell carcinoma and adenocarcinoma than that in adenosquamous carcinoma,and the high expression rate of STX8 was not observed in large cell carcinoma.There were no significant differences in expressions of STX8 in NSCLC patients with different gender,ages,tumor diameters,TNM stages and with or without lymph node metastasis (P＞0.05).Conclusion A high expression of STX8 in NSCLC tissues may be correlated with the occurrence and development of NSCLC.

OBJECTIVE:To investigate the situation of pharmacoeconomic researches about lipid-lowering drugs in China, and to seek the regimen with good cost-effectiveness in order to provide reference for rational drug use in the clinic. METHODS:Retrieved from CNKI and Wanfang database,pharmacoeconomic literatures about lipid-lowering drugs,published in domestic jour-nals during 2011-2015,were included to discuss the problems of pharmacoeconomic researches about lipid-lowering drugs and put forward related suggestions. RESULTS:Rosuvastatin and other medicines showed good cost-effectiveness,while there were many problems of domestic published pharmacoeconomic researches about lipid-lowering drugs,such as different research methods,dif-ferent treatment courses,different methods of cost calculation,single effect index and absence of ADR. On the whole,the research-es were low in quality,which led the difficulty of accurately obtaining the drugs with best cost-effectiveness. CONCLUSIONS:In the future,related researches should confirm research duration and health output index,effect index and evaluation method accord-ing to disease types and research objectives;enhance the unity of research and design methods;pay attention to cost discount;in addition,strengthen pharmacoeconomic researches about lipid-lowering TCM and compare it with chemical drugs.

PurposeAdrenal schwannoma is rare and quite difficult to diagnose before operation. This paper aims to analyze the CT findings of adrenal schwannoma to improve the recognition and diagnosis of this disease.Materials and Methods The CT findings of 6 patients with adrenal schwannomas proved by operation and pathology were retrospectively analyzed.Results Four schwannomas were located in the right adrenal and 2 in the left adrenal. The tumors, with diameters ranging from 3.0 cm to 6.4 cm, mean (4.5±1.3) cm, had well-defined margin. The densities of all the masses were close to or slightly lower than those of kidneys on plain scan images, with mean CT attenuation value of (32±7) HU. Three masses showed homogeneous density and the other 3 were mildly heterogeneous with patches of lower density. All the 6 schwannomas were enhanced mildly or moderately after intravenous administration of contrast material and showed gradual enhancement mode. They showed mild homogeneous or flocculent enhancement on arterial phase and had gradual progress on venous and delayed phases. The mean increase of CT attenuation value was (13±2) HU on arterial phase, (18±4) HU on venous phase and (23±4) HU on delayed phase. Only 1 mass showed some patches of cystic degeneration without enhancement inside.Conclusion Adrenal schwannoma should be included in the differential diagnosis of solid nonfunctioning adrenal tumors. Features such as relatively homogeneous mass, mild to moderate enhancement and gradual enhancement mode after contrast enhancement are possibly the unique CT manifestations of adrenal schwannoma.

Objective To study the roles of apoptosis and expression of the related genes in minor labial salivary gland of patients with primary Sjogren′s syndrome (pSS). Methods Biopsies of minor submucosal labial salivary gland (SG) were obtained from 30 patients with pSS and 10 control individuals. The in situ end labeling and immunohistochemical staining were used to detect the apoptotic cells and the expression of Fas, FasL and Bcl-2. Results The percentage of apoptotic acinar and ductal epithelial cells (AEC and DEC) in labial salivary glands of patients with pSS was significantly higher than that of control respectively, but the percentage of apoptotic infiltrating mononuclear cells (IMC) showed no significant difference compared with that of control, pSS AEC and DEC showed increased expression of Fas/FasL and decreased expression of Bcl-2, whereas pSS IMC showed increased expression of Fas, Fas/FasL and Bcl-2. There was significant positive correlation between the percentage of apoptotic cells and the cells expressing Fas and FasL in pSS AEC DEC and IMC, respectively, and there was significant negative correlation between the percentage of the apoptotic cells and that of cells expressing Bcl-2 in pSS DEC and IMC, but there wasn′t correlation between the percentage of the apoptotic cells and that of cells expressing Bcl-2 in pSS AEC. Conclusions The apoptotic cells increased in the epithelial cells and decreased in IMC of the labial salivary glands may be one of the mechanisms leading to the glandular destruction found in pSS. In pSS labial salivary glands, the expression of Fas and FasL may promote apoptosis, while the expression of Bcl-2 may inhibit apoptosis. The increased expression of Bcl-2 in pSS IMC indicates that IMC may be able to escape apoptosis, resulting in inflammatory cell foci.
