Acta Anatomica Sinica 1957;0(04):-
Objective To obtain stable-expressing cell lines which could constantly express tropic1808 gene and investigate the effect of tropic1808 by detecting the expression level of NF-H in PC12 cells. Methods The recombinant tropic1808 plasmid was constructed and transfected into PC12 cells.PC12 cells stable-expressing tropic1808 were established by G418 selection and confirmed by Western blot.The expression of NF-H in the PC12 stable-expressing tropic1808 was observed by RT-PCR,real time PCR,Western blot analysis and cytohistochemistry methods. Results Western blot confirmed that tropic1808 gene could express stably in PC12 cells.The data of RT-PCR,real time PCR,Western blot and cytohistochemistry all demonstrated that the expression of NF-H was increased in PC12 cells stable-expressing tropic1808.Conclusion PC12 cell lines stable-expressing tropic1808 were obtained and the expression of NF-H up-regulated in the PC12 cells stable-expressing tropic1808 gene.

China Pharmacy 2017;28(11):1510-1513
OBJECTIVE:To observe long-term efficacy of intensive rosuvastatin therapy in the treatment of acute coronary syn-drome (ACS) and explore its possible mechanism,so as to provide reference for clinical diagnosis and treatment. METHODS:ACS patients receiving rosuvastatin after cured in our hospital during Jan. 2013-Jan. 2015 were divided into observation group(55 cases)and control group(47 cases)according to the dose of rosuvastatin. Under same guidance of physicans,2 groups were addi-tionally given Rosuvastatin calcium tablets(20 mg for observation group,10 mg for control group,qd,po)orally on the basis of routine treatment. Both groups were treated for 1 year. The incidence of 1-year accumulative main adverse cardiac event (MACE) were compared between 2 groups as well as the levels of blood lipid and serum cytokines,the occurrence of ADR before treat-ment,after 3 months of treatment. RESULTS:The incidence of accumulative MACE in observation group was significantly lower than control group,with statistical significance (P<0.05). After treatment,the levels of TC and LDL-C in 2 groups were de-creased significantly;the level of LDL-C was inCreased significantly compared to before treatment,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The levels of IL-1β and TNF-α in 2 groups were decreased significantly (P<0.05);the observation group was significantly lower than the control group,with statistical signifi-cance (P<0.05). The peripheral blood LDL-C was positively correlated with IL-1β and TNF-α in observation group after treat-ment,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Intensive rosuvastatin therapy can significantly improve the long-term prognosis for ACS patients,which may associate with lipid metabolic regulation and anti-inflammatory effect.
5.Determination of Trace Cadmium (Ⅱ) in Water by Spectrophotometry in Cadmium (Ⅱ)-Potassium Iodide-Malachite Green-Gelatine
Journal of Environment and Health 2007;0(09):-
Objective To establish a high sensitive spectrophotometry for determination of trace cadmium in the water. Methods A complicated ion-association complex of Cd(Ⅱ)-potassium iodide-malachite green was formed in the phosphate acid, and the addition of gelatine could enhance the sensitivity of the reaction.The maximum absorption of the ion-association complex was at 680 nm,the effect of experimental conditions such as the reagents concentration,the temperature and the influence of foreign matters were considered.Results In the optimum condition(6.0 ml of 40% potassium iodide-aseorbic acid solution,0.5 ml of 5.0 mol/L phosphate acid solution,0.5 ml of 0.5% gelatine solution,1.5 ml of 1.0?10~(-3)mol/L malachite green solution in a 25ml volumetric flask,diluted with water and mixed well and determined immediately),the linear regression equation was △A=0.011+ 0.957 c,r=0.998 5.Beer's law was obeyed in the range of 0.02 ?g/ml to 0.80 ?g/ml for Cd(Ⅱ)and the limit detection was 0.02 ?g/ ml.The composing ratio of the complex was MG:Cd:I=2:1:4,and its apparent molar absorptivity coefficient was 1.08?10~5 L/(mol? cm).The recovery rates of Cd(Ⅱ)were 97.0%-101.5%,RSDs were 1.36%-3.58%.Conclusion This method is sensitive,simple, rapid and is applicable to the determination of the trace Cd(Ⅱ)in water.
6.Retrospective Analysis of Zhu Yun Pill in Treating 133 Cases of Infertility due to LPD
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
Objective: To investigate the effects of Zhu Yun Pill(ZYP) in the treatment of infertility due to luteal phase defect(LPD).Methods: 163 infertility patients due to LPD were randomly divided into three groups in terms of ZYP group,progesterone group and combination group(ZYP and progesterone).Then the therapeutic efficacy was judged by the pregnancy rate(PR),endometrial biopsy,the level of serum hormone and basal body temperature before and after the treatment.Result: 40 women were pregnant in ZYP group(cure rate,33.33%),8 in the progesterone group(cure rate,26.67%) and 9 in the combination group(cure rate, 69.23%).The symptomatic amelioration and total effective rate of ZYP group were obviously higher than single exogenous progesterone group(P
7.Application of proteomics in the studies of cerebral ischemic preconditioning
International Journal of Cerebrovascular Diseases 2009;17(1):63-66
Proteome is defined as all proteins expressed in a cell, a tissue or an organism. Proteomics, a science of understanding the life activity law at the whole protein level, takes proteome as a research object; it is also a scientific method for quantitative detection of one or more protein populations or proteomes in a cell or tissue. Cerebral ischemic preconditioning has been one of the research hotspots in the field of neuroscience for decades. Its neuroprotec-five mechanism is associated with the changes of protein expression levels after cerebral ischemia, Therefore, proteomics has become more and more important in its mechanism study. This article mainly presents the major techniques of proteomics and their application in the studies of cerebral ischemic preconditioning.

Chinese Journal of Radiology 2008;42(10):1050-1052
Objective To estimate the effective dose during 64-slice CT examination on head,chest and abdomen and determine the conversion coefficient of effective dose and dose length product(DLP).Methods The plain CT scan wag performed in 48 cases on head,50 cases on chest and 45 cages on abdomen using GE Lightspeed 64-slice spiral CT.1The Kv,Ma,scan time,CTDIvol,and DLP were recorded in each examination.Effective dose on patients Was estimated using the SR 250 software.Results The effective dose on head,chest and abdomen was(3.1±0.1),(6.9±0.1)and(8.0±0.1)mSv,and the conversion Coeffieient was 0.0025,0.0191 and 0.0166 mSv·mGy-1·cm-1 respectively.Conclusion CTDIvol、DLP and effective dose were recommended for patient dose control during CT examination.The conversion factor of effective dose and DLP were recommended for radiation risk evaluation during different X-ray examinations.
9.Research progress on correlation between subclinical hypothyroidism and cardiovascular diseases
Tianjin Medical Journal 2016;44(4):509-512
Subclinical hypothyroidism is a metabolic disease, defined by increased thyroid-stimulating hormone (TSH) and accompanied by normal thyroid hormone levels. Recent years, many domestic and foreign studies have showed that sub?clinical hypothyroidism may be related with atherosclerosis and left ventricular diastolic dysfunction, which increasing the risk and mortality of cardiovascular diseases. Subclinical hypothyroidism may be associated with lipid metabolic disorders, hypertension, coagulation dysfunction, endothelial dysfunction, abnormal glucose metabolism, homocysteine, C-reactive pro?tein and lipoprotein. At present, controversy persists on the subclinical hypothyroidism. The aim of this study is to review the correlation between cardiovascular diseases and subclinical hypothyroidism.
