Glucocorticoids (GC) exert a broad effect on the body and have been extensively used clinically.It is well known now that GC can act via both genomic and nongenomic mechanisms.Genomic effects of GC have been well reviewed elsewhere.Here we focus on the current understanding of nongenomic effects and discuss their biologic significance as well as the remaining problems in this field.

OBJECTIVETo investigate the clinicopathologic and immunohistochemical features as well as the differential diagnoses of the solid variant of mammary adenoid cystic carcinoma with basaloid features.
METHODSClinical and pathological data were collected in four cases of the solid variant of mammary adenoid cystic carcinoma with basaloid features, and microscopic pathological examination and immunohistochemistry EnVision method were performed. The relevant literature was also reviewed.
RESULTSThe four patients were female, with age ranged from 46 - 65 years old (average 56 years) and the maximum tumor diameter ranged from 1.5 to 2.5 cm. Microscopically, the tumors exhibited a predominantly solid architecture with a myxoid or hyalinized stroma. The tumor cells showed moderate to marked nuclear atypia, and a basaloid appearance with scanty cytoplasm and inconspicuous nucleoli, and ≥ 5 mitotic figures per 10 high power fields. Glandular space embedded within tumor islands could be noticed. These spaces were genuine glandular structures and the cells lining these true glandular lumens had more abundant and eosinophilic cytoplasm. Pseudoglandular spaces of cribriform pattern or variable shape were also occasionally seen, and these cysts contained homogenous eosinophilic material. Focal necrosis was found. All cases were negative for ER, PR and HER2. Immunohistochemical staining for CK5/6, CK7 and CK14 was positive in the genuine glandular structures. All cases were positive for CD10, but also positive with varying intensity from weak to strong for vimentin and CD117. Staining for Ki-67 in three patients showed 10% - 50% positive.
CONCLUSIONSThe solid variant of mammary adenoid cystic carcinoma with basaloid features is a histologically distinctive and also a rare subset of the mammary adenoid cystic carcinoma. Awareness of its pathological features can help with the diagnosis as well as differential diagnosis. More cases are still needed for accurately assessing the prognosis of this particular tumor.

The investigation on the chemical constituents of Anabasis aphylla L. was carried out by using various chromatographies, such as silica gel, Sephadex LH-20 and RP-C18 column chromatography. Further detailed investigation on the fraction of the ethanol extract of Anabasis aphylla L. yielded one new compound p-acetyl-phenol 1-O-beta-D-xylopyranosyl-(1-->2)-beta-D-glucopyranoside (1), together with five known compounds: piceine (2), isorhamnetin (3), quercetin (4), rutin (5) and isorhamnetin-3-rutinoside (6). Their structures were elucidated by spectral analysis such as NMR and MS. Among these compounds, compounds 2-6 were isolated from this plant for the first time.

OBJECTIVETo construct differential expression profiles of adenoid cystic carcinoma cell lines for screening candidate genes related to metastasis and to verify some candidate genes in adenoid cystic carcinoma.
METHODSRestriction fragments differential display PCR (RFDD-PCR) was used to set up gene expression profiles of adenoid cystic carcinoma cell lines-ACC-M and ACC-2, with high and low metastasis potential respectively. Candidate genes were screened through bioinformatics analysis. Then, a gene family of these candidate genes was checked using semi-quantitative reverse transcription-PCR(RT-PCR).
RESULTSTwo gene expression profiles including 5420 gene fragments were constructed, 12 genes of a family called matrix metalloproteinase genes (MMPs) were observed obvious differentially expressed between two cell lines. Results of semi-quantitative RT-PCR also identified this different expression of MMP2,MMP7,MMP9,MMP14,MMP15 and MMP24.
CONCLUSIONThe construction of gene expression profiles of ACC-M and ACC-2 cell lines makes the foundation for seeking the target genes of adenoid cystic carcinoma. MMP2,MMP7,MMP9 and MMP15 may be relevant with carcinogenesis, development and metastasis of adenoid cystic carcinoma, and different metastasis potential may result from different subtype of MMPs gene family.

Objective·To analyze the basic medical insurance policies for children in Shanghai in 2011 and 2017, and compare with those of the other three municipalities to understand the basic medical security status of children in four municipalities in China and analyze the existing problems. Methods?·?The current effective children's basic medical insurance policies and child critical illness insurance policies and related insurance systems in four municipalities were collected systematically. The types of basic medical insurance for children in various municipalities and their funding standards, their own expenses and the proportion of government subsidies, the proportion of outpatient emergency payoff lines and reimbursement at all levels of medical institutions, and the coverage and coverage of major illness insurance reimbursement were collected and compared mainly. Results?·?The basic medical insurance for children in Shanghai is a "double insurance" system, which contained children's hospitalization fund and basic medical insurance for urban and rural residents. The basic medical insurance for children in other municipalities mainly consisted of basic medical insurance for urban (rural) residents. Compared with 2011, the level of financing and the reimbursement of the basic medical insurance for urban and rural residents and of the children's hospitalization fund in Shanghai in 2017 was increased. In 2017, the level of financing of basic medical insurance for urban and rural residents in Shanghai was 1?100 yuan, which was slightly lower than that of Beijing medical insurance for urban residents and new rural cooperative medical insurance and was higher than that of basic medical insurance for urban and rural residents in Tianjin and Chongqing, and the individual payment level of Shanghai was the lowest. The hospitalization payoff lines in Shanghai were lower than those of other municipalities. Shanghai's outpatient and inpatient reimbursement levels were higher those of than other municipalities. There wasn't a capping line in Shanghai. There were capping lines in other municipalities. There was a great difference in the insurance policy of the major diseases in four municipalities. Conclusion?·?According to their own actual conditions, models for children's medical care systems that suited each municipalities’ social and economic development have been established. Shanghai children's basic medical insurance basically meets the needs of children's growth but needs improvement in terms of the type and level of medical security for major illnesses.

OBJECTIVETo investigate the association between birth defects and dietary nutrient intake in a high risk area of China.
METHODSA dietary survey was performed and serum folic acid was measured in women whose pregnancy was affected by neural tube defects (NTDs) or unaffected by any birth defects (BDs) in Zhongyang and Jiaokou Counties in Shanxi Province of China.
RESULTSThe local average consumption of foods including dark green vegetables, fruits, fat and meat, and nutrient intake (e.g., energy, protein, retinol, riboflavin, vitamin E, and selenium) were lower than the national average level. In women of childbearing age, these regions, the intake of nutrients was much lower than the recommended nutrient intake (9%-77%). The case-control dietary nutrition study of women whose pregnancy was affected by BDs (including NTDs and congenital heart defects) demonstrated that, in early pregnancy, adequate nutrition (i.e., eating meat, fresh vegetables, fruit more than once a week) was a protective factor, while eating germinated potatoes was a risk factor. The geometrical mean (p5-p95) of serum folic acid in women with NTD birth defects was 9.6 nmol/L (3.6, 23.03), which was significantly lower than that in normal women (14.03 nmol/L).
CONCLUSIONWomen of childbearing age in the two counties of Shanxi Province, China, have a marked insufficient intake of some nutrients, especially folic acid, zinc, vitamins A and B12. This nutrient deficiency may be an important risk factor for the high prevalence of birth defects in these regions. Therefore, adequate dietary nutrition in early pregnancy can prevent BDs.
