Hypoxia- inducible factor-1 ( HIF-1) promotes tumor deterioration, invasion and metasta-sis. Treatment targeting the HIF-1 signal pathway is becoming a hot research. In addition to uniquely selective inhibition of topoisomerase Ⅰ(Topo Ⅰ) ,the recent studies show that camptothecin compounds can regulate the activity of HIF-1 through decreasing HIF-1 protein translation and have been classified as a non-selective chemical inhibitor of HIF-1.

Sphingosine analogue FTY720 exerts good immune suppressive effect by inducing lymphocytes apoptosis and homing, which can be used for organ transplant rejection as well as anti-autoimmune disease treatment. Recent studies have found that FTY720 plays anti-tumor potential by inducing growth arrest and apoptosis as well as inhibiting tumor metastasis.

[Objective] Sorting and summing up Professor ZHANG 's clinical experience in the diagnosis and treatment of atlanto-axial joint subluxation, to develop the thought of clinical diagnosis and treatment of the disease. [Methods]Via studying with professor ZHANG, and collectting some cases,consulting the related literature and data.Finally, discuss and summarize it. [Results] Diagnosis found and appliedFour tenderness(Below the foramen magnum, trapezius muscle and at the junction of the skull,fengchi point,wangu point).Method combined with primary symptom and signs, X-ray. Treatment, application of error correction manipulation, light effect;And with local acupuncture point injection, menstruation invigorates the circulation of reinforcement. [Conclusion] Professor ZHANG's method of diagnosis and treatment of atlanto-axial joint subluxation is unique,clear, simple, has obvious curative effect, worth clinical application and promotion.

AIM:To establish a method for determining notoginsenoside R_1,ginsenoside Rg_1 and ginsenoside Rb_1 in Jingkang Capsules(Radix Rehmanniae praeparata,Radix Polygoni multiflori,Radix et Rhizoma Notoginseng,etc.). METHODS: A Diamonsil C_(18) column(250 mm?4.6 mm,5 ?m) with acetonitrile-water as the mobile phase was used for gradient elution,the flow rate was 1.0 mL/min and the UV detection wavelength was at 203 mn. RESULTS: There was a good linear relationship at a range of 0.327-2.180 ?g for notoginsenoside R_1(r=(0.999 4))(the average recovery was 98.23% with RSD of 1.53%(n=6)),0.909-6.060 ?g for ginsenoside Rg_1(r=1.0)(the average recovery was 99.04% with RSD of 1.00%(n=6)),0.672-4.480 ?g for ginsenoside Rb_1(r=0.999 8)(the average recovery was 98.17% with RSD of 1.31%(n=6)).CONCLUSION: The method is simple,quick and accurate.It can be used for the quality control of Jingkang Capsules.

Objective To determine the content of two original constituents of Liuwei Dihuang Wan migrating to blood. Methods HPLC- fingerprint of the preparation and drug- containing serum fingerprint were established by RP- HPLC. Based on the fingerprints, the original constituents migrating to blood were identified and determined by comparing with the standard. Results Loganin and paeonol were identified as the original constituents migrating to blood; the loganin content was 0.93? 0.01 mg/g and the paeonol was 0.37? 0.01 mg/g. Conclusion Using the constituent content migrating to blood as the parameter, this method will provide scientific evidence for improving the quality control of Liuwei Dihuang Wan. 

OBJECTIVE:To provide experience and reference for the reform ofintegration of medicine and nursingunder the strategy ofHealth China 2030. METHODS:By literature analysis,the demand characteristics and supply situation ofinte-gration of medicine and nursingservice model in China were analyzed. The development bottleneck ofintegration of medicine and nursingservice model in China was discussed to put forward countermeasures and suggestions. RESULTS&CONCLUSIONS:Integration of medicine and nursingis a new model of the development of pension services in China. Throughout whole country, it is still in the stage of exploration and practice. There are some problems,such as serious inadequate beds,low participation of private pension institutions,pension service quality ofintegration of medicine and nursinghaving to be improved,weak market competition of pension institutions,social forces participation having to be improved,big demand gap of medical and nursing staff,inadequate high-quality medical and nursing talent. A clear positioning ofintegration of medicine and nursingservice model in China should be put forward andintegration of medicine and nursingmonitoring system should be improved. It is suggested to establish service complaint mechanism of pension institutions,encourage the active participation of diverse social forces,broaden the financing channels ofintegration of medicine and nursing,build service information sharing platform ofintegration of medi-cine and nursing,establish electronic health records for the elderly and set up maintenance personnel training mechanism so as to promote the rapid development of the reform ofintegration of medicine and nursing.

Diabetic retinopathy (DR) is one of the most significant microvascular complications of diabetes,and its incidence increases with the prolongation of DM;meanwhile,it can lead to severe vision loss.Recently,the pathogenesis of DR has been one of the focuses both at home and abroad,but the basic mechanisms are not fully elucidated.More and more scholars believe that DR may be a chronic and low degree of inflammatory response.Moreover,it is well established that microglia is a monocyte-macrophage,with antigen-presenting function.Especially in the retina,as microglia is activated,followed by the release of a large number of inflammatory factors,microglia involves in DR inflammatory response.Understanding the activation mechanism of microglia can provide a new perspective for the prevention and treatment of DR.Therefore,recent advances in activation of microglia in diabetic retinopathy and its intervention mechanism will be reviewed in the article.

A dynamic electrocardiogram record system based on MSP430 SCM is developed in this paper. MSP430 SCM has ultra-low power consumption and a high integration level. The gathered ECG data are stored on a CF card. With low power consumption and being portable, the system is especially suitable for the occasion with the battery as power supply.

Objective To study the effect of chitosan/tricalcium phosphate(CTCP)on the attachment and proliferation of bone marrow stromal cells(BMSCs)cultivated in vitro and explore their biocompatibilities.Methods The CTCP was prepared by freeze-drying.BMSCs were cultivated in vitro,collected and seeded onto the surface of CTCP.Cell attachment and proliferation were obesrved using inverted light microscope and scanning electron microscopy(SEM).The cell proliferation was tracked by MTT method 2,4,6,8 d after seeding.Results BMSCs were fibroblast-like 2 d after seeding.The mean number of cells was(360?20) and(76?18),respectively,in the experimental and control group per 100 eyesight field,the difference was significant(P

group A)(P0.05).In all the 3 groups,the BIS decreased to the lowest level at T2,and then increased at T3 and T4,and the BISs at T2,T3,and T4 were significantly different from that at T1(P
