1.Application of bonding appliance combined with protracting mask to treat early primary crossbite
Journal of Practical Stomatology 2001;0(03):-
Objective: To evaluate the effect of a new method to treat early primary crossbite . Methods: 20 cases (2.8~6.5 years old ) with anterior crossbite were treated by bonding appliance combined with protracting mask. Cephalometric radiographs were taken and analyzed before and after treatment. Results: On average,in all the 20 cases the maxilla were moved 2.06 mm forward ,mandibular were turned 2.45?downward and backward ,the anterior crossbite was corrected and the face profile was improved satisfactorily.The treatment was conducted for 1.7 months on average. Conclusion: Using bonding appliance combined with protracting mask to treat early primary crossbite can achieve good effects for young children .
2.Diterpenoid Alkaloids in the Roots of Aconitum Bulleyanum Diels
China Pharmacist 2017;20(9):1525-1528
Objective: To study the chemical constituents in the roots of Aconitum bulleyanum Diels. Methods: The air-dried roots of A. bulleyanum were powdered and extracted by methanol with percolation. After removing the solvent under reduced pressure, the crude extract was dissolved in 1. 5% HCl solution, and then basified to pH 9 by NaOH (5%) and extracted by ethyl acetate to ob-tain crude alkaloidal extract after ethyl acetate removal. The alkaloidal extract was isolated and purified by column chromatography, and their structures were identified based on spectral analysis ( 1 H-NMR, 13 C-NMR, MS) . Results:Totally 12 diterpenoid alkaloids were isolated from A. bulleyanum and characterized as foresaconitine (1), crassicauline A (2), chasmanine (3), talatisamine (4), 14-debenzoyl-franchetine (5), pengshenine A (6), crassicautine (7), yunaconitine (8), franchetine (9), liljestrandisine (10), transconitine B (11) and pseudoaconine (12). Conclusion:Compounds 3-7, 10-12 are isolated from this plant for the first time.

GRP78/Bip,which was first identified by scientists in 1977,is a major endoplasmic reticulum (ER)chaperone that has a variety of function.In tumor tissue,GRP78 is high expression and ectopic expression;participate in the development of tumor,ER-stress state and ectopic distribution on the cell surface,in the form of receptors involved in signal transduction. Therefore,GRP78 as an tumor therapeutic targets,biomarkers of tumor and prognosis of tumor biological markers,plays an important role in the tumor research.In recent years,domestic and foreign scholars have found that in the non-cancer disease (viral infectious disease cardiovascular disease diabetes neurodegenerative disease etc),GRP78 is high expression,indicate its application prospect.This article makes a brief overview on the molecular biological characteristics of GRP78,role in tumor pathogenesis and therapeutic significance and application prospect in non-tumor disease.

Objective To investigate the identification of MiR-221 regulates apoptosis by targeting PUMA in lung cancer. Methods The express levels of miRNAs that collected from lung cancer tissue and lung benign lesion were tested by the particular kid they made,analyzed the correlation between individual miRNA.Results 9 6 possible regulated PUMA related miRNAs had been screened through the bioinformatics database,then customized it into the special kit to test the expression with real time fluorescent PCR.The results showed that 10 types miRNAs were up expression in lung cancer tissue,miR-NA221 were selected for deep analyze.Results with rank sum test showed statistical significance (P<0.05)in lung cancer and para cancer tissue.There were statistically significant differences in the expression between metastasis and nonmetastasis (P<0.05),but had nothing to do with the pathological types.Conclusion Real time fluorescent PCR test showed several types of PUMA related miRNAs up-expressed in tissue lung,which indicate miRNA have relationship with PUMA in gene express regulation and cancer generation and development.Pression situation and clinic pathological parameters.Expression of miRNA-221 in lung cancer was associated with tumor metastasis.

Diabetes mellitus has became a growing public health problem,its acute and chronic complications threaten the patient's dramatically.HbA1c is recognized as the gold standard for blood glucose evaluation in patients with diabetes It has reported that the incideut rafe of diabetes related will decline remarkably when HbA1c decline by 1%,so the detection accuracy of the HbA1c is very important in the diabetes patient's management.Uncertainty of measurement can reflect the detation accuracy,which will benifite the value of HbA1c.

Objective To observe the effect of Yixin Jiangya Capsule (YXJYC) on serum insulin-like growth factor-1 (IGF-1) level in patients of left ventricular hypertrophy (LVH) of primary hypertension at stageⅡ with Yinxu Yangkang and blood stasis syndrome (YXYKBSS). Methods 93 patients were randomly divided into the treated group (62 patients) and the control group (31 patients). The two groups were both treated with enalapril, and the treated group was treated with YXJYC simultaneously. Treatment course of the two groups was 6 months. Radioimmunoassay was used to examine the level of serum IGF-1 before and after treatment in the two groups, compared with that of 30 healthy persons. Results Before treatment, serum IGF-1 level was significantly higher in both groups than that in the healthy persons (P

9.The detection of hemoglobin A1c in clinical application
Chinese Journal of Laboratory Medicine 2012;35(6):501-504
The hemoglobin A1c(HbA1c) results can reflect the average level of blood glucose over the past 2-3 months,its clinical application value is transforming from evaluation indicator to diagnosis indicator.The application of HbA1c as a diagnostic indicator of diabetes is limited by many factors,such as multi-factor influence on measurement and its late start on standardization process in our country,optimal cut-point and the defect of HbA1c existing in the molecular level,etc.Therefore,clarifying the limitations of HbA1c in the practical application is of great significance for its clinical application.
