1.Using brain natriuretic peptide to quantitatively analyse the therapeutic effect of congestive heart failure
Chinese Journal of Primary Medicine and Pharmacy 2010;17(11):1488-1490
Objective To explore the sensitivity and constancy of BNP in evaluating the therapeutic effect of congestive heart failure.Methods 80 patients made a definite diagnosis of congestive heart failure were selected and whose cardiac functional grading of NYHA,BNP and left ventricular ejection fraction (LVEF) were determined respectively pre-treatment,one week,one month and three months after-treatment.Statistical analysis on the difference of therapeutic effect was performed for each case.Results No statistical difference was found between the amplitude of BNP and LVEF in one week and on one month, three months pro-treatment by the scheme of captopril combining with metoprolol (P>0.05 ).But between the BNP and the cardiac functional grading,statistica difference was found in the fitst week pro-treament(P<0.05),when on one month and three months after treatment the statistical difference still not found(P>0.05).Conclusion BNP dynamic measuring had the hige sensitivity and constancy in quantitatively analysing the therapeutic effect of congestive heart failure which could be used as a reliable tool for evaluating the therapeutic effect of congestive heart failure.
2.Research on Regional Differences of Technical Efficiency under Medical and Health System in China
Chinese Health Economics 2014;(3):30-32
Objective:To study on regional differences of technical efficiency under medical and health system in China, and analyze on the influence factors of technical efficiency. Methods: Based on the provincial panel data from 2002 to 2011, the stochastic frontier production function of healthcare system was established for empirical analysis. Results and Conclusion: Overall, the average technical efficiency of medical and health system in China presented an increasing tendency, however, a significant difference was found in regional efficiency. The non-efficiency of medical and health system in different areas could be reduced by the proportion of tertiary hospitals in all medical institutions, the ratio of profit-making medical institutions in all medical institutions and the population density;while the influences of highway density and per capital education year on technical efficiency in different areas are different.

The occurrence and development of tumor depends not only on the tumor itself,but also depends on the soil survival of tumor cells,that is the tumor microenvironment.Studies confirm that the changes of blood vessels and hypoxic of tumor microenvironment maintain the stemness of cancer stem cell,and further strengthen the ability of tumor invasion and metastasis.Studying the molecular mechanism of tumor development from angiogenesis and lack of oxygen can provide new ideas for the clinical targeted therapy.
4.Study on effect of various extract of Sini Decoction on reproductive organ and sexual hormone of hypothyroidism rats with syndrome of yang deficiency
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(01):-
Objective:To study the effect of various extract of Sini Decoction on hypothalamus-pituitary-sexual glands axle of hypothyroidism rats with syndrome of yang deficiency, and discuss the mechanism of Sini Decoction in reinforcing yang. Methods: The model of deficiency of both the spleen-yang and the kidney-yang were induced by PTU solution. After the model were confirmed, the rats in Sini Decoction group were administered with Sini Decoction . At the end of the experiment, all the rats were sacrificed and the blood were sampled to check the level of Sex hormones , the reproductive organs were weighed, the testicle were sliced to check their pathological change. Results:Various extract of Sini Decoction can reduce the increase of weight of orchis and prostate of model rats, reduce their pathologic damage, and increase the level of testosterone. The alcohol extract of Sini Decoction has obvious therapetic effects. Conclusion: Sini Decoction can improve the sexual hormone level and weight index of reproductive organs of hypothyroidism rats with syndrome of yang defi ciency.
5.Relationship between inflammation and macroangiopathy in type 2 diabetes mellitus and the protective role of pioglitazone in macroangiopathy
Chinese Journal of Diabetes 2008;16(8):491-492
The changes of the levels of C-reactive protein,endothelin and nitric oxide before and after pioglitazone treatment in type 2 diabetic patients suggested that inflammation participated in the pathogenesis of diabetic macroangiopathy and pioglitazone can protect vessels

The growth associated protein(GAP 43) and neural cell adhesion molecule (NCAM) play an important role both in promoting neurite outgrowth and synaptic plasticity. GAP 43 is a neuron specific phosphoprotein that is highly expressed during the development of the central nervous system, nerve regeneration and the modulation of synaptic function, and it is frequently used as a marker for sprouting. GAP 43 may be involved in G protein interaction, membrane binding, calmodulin binding and protein kinase C phosphorylation. The various interactions, specified by the structural domains, are thought to underlie the role of GAP 43 in synaptic plasticity, participating in membrane extension during neuritogenesis, in neurotransmitter release and long term potentiation. NCAMs involve in the intracellular signaling cascades and stimulate the axonal growth, GAP 43 function is essential for NCAM stimulated neurite outgrowth and that much of this appears because of the phosphorylation of GAP 43 via the FGF receptor dependent stimulation of arachidonic acid. NCAM can accelerate the phosphorylation of GAP 43.
7.Diagnosis and differential diagnosis of ectopic pregnancy by magnetic resonance imaging
Journal of Practical Radiology 2016;32(3):388-391
Objective To analyze retrospectively MRI features of ectopic pregnancy correlated with pathology.Methods Eleven patients with pathologically proved ectopic pregnancy were enrolled in this study:one with cornual pregnancy,six with interstitial pregnancy,two with tubal isthmus pregnancy,one with ampullary pregnancy,and one with primary abdominal pregnancy.Six under-went MRI plain scan,and five underwent MRI both plain scan and enhancement scan.We evaluated the location,the size,the signal intensity of the gestational sac (GS),vessels around the GS,dilatation tubal,hematosalpinx and hemoperitoneum.Changes of the thickness of the endometrium,functional ovarian cysts and ovarian corpus luteum were also evaluated.Results Among these eleven patients,GSs were detected in ten patients.The locations of the GSs on MRI were corresponding with the results of surgical explora-tion.GS was not detected in only one patient with tubal pregnancy,but hematosalpinx and pelvic hematocele could be seen in MRI. Conclusion MRI is an effective modality for evaluating GS and its adjacent organs.The imaging features of GS and other indirect signs can be helpful to the diagnosis and differential diagnosis of ectopic pregnancy on MRI.
8.Recent advance in osteoclast regulation and osteoporosis
Chinese Journal of Pathophysiology 2000;0(08):-
Osteoclast (OC) are bone resorbing cells whose development and activity are under the influence of osteoblast (OB). The potential association between those two cell lineages is an area of significant interest. It was not until 1998 that osteoclast differentiation factor (ODF) and osteoprotegerin (OPG) was cloned. The two novel TNF superfamily members have been recently demonstrate to be the key extracellular regulators of osteoclasteogenesis and bone resorption both in vivo and in vitro, and they play important roles in osteoporosis development, diagnosis and treatment.
