Social capital has become an important service provider of medical and health undertakings in China.Its active participation in health management industry services promotes the overall development of China's health industry.The paper discusses the four important roles of social capital in health management industry,and puts forward four development strategies,including the transformation to the high-end health management services,and undertaking basic health management services and public and private health management of the joint venture and the development of specialized health management service.

As an important basic industry group of health industry,health management provided beneficial development environment for health management industry,which had important significance on improving the development of the whole health industry.It analyzed the development trend of domestic and foreign health management industry and the current problems of the health management industry development in China.The development strategies of health management industry in China were discussed from guarantee mechanism,system construction,new mood development,improving the elements,health and culture training,payment mechanism innovation and exploring the characteristics.

AIM To investigate the possible role of the mitochondrial transmembrane potential (??m) and caspase 3 in arsenic trioxide(As 2O 3)-induced apoptosis of cancer cells. METHOD Namalwa, SGC7901 and Bcap37 cell lines were used as in vitro models. Apoptosis was confirmed by sub-G 1 cells content as well as phosphatidylserine(PS) externalization. The ??m was detected on flow cytometry through double staining of Rhodamine 123(Rh123) and popidium iodide(PI). In addition, the effect of DEVD-CHO, a selective inhibitor of Caspase 3, on As 2O 3-induced apoptosis was studied. RESULT The As 2O 3-induced apoptosis closely associated with the externalization of the ??m and the activation of Caspase 3. As 2O 3 induced cells necrosis when Caspase 3 was inhibited. CONCLUSION As 2O 3 may selectively activates Caspase 3 after it induces externalization of ??m, which causes cancer cells apoptosis.

OBJECTIVE:To prepare ganciclovir hydrochloride chitosan eye drops and establish its quality control method.METHODS:The eye drops was prepared using chitosan as thickening agent and synergist with ganciclovir as principal agent.The content of ganciiclovir was determined by HPLC.The stability of the preparation was investigated as well.RESULTS:The prepared eye drops was colorless transparent glutinous limpid liquid with its identification items all up to the related standards stipulated in Chinese Pharmacopoeia(2005 edition).The linear range of ganciclovir was 5～80 mg?L-1(r=0.999 9) with average recovery of 99.02%(RSD=0.71%).The preparation was stable under light with all its indexes showed no obvious change in the accelerated test at 6 month.CONCLUSION:The preparation technology is simple and feasible and the quality of preparation is stable and controllable with a validity duration tentatively set at 2 years.

OBJECTIVE: To compare the pharmacokinetics and relative bioavailability between ganciclovir-chitosan eye drops and ganciclovir eye drops in rabbit eyes. METHODS: Japan big-eared rabbits were randomly assigned to the receive 50 ?L ganciclovir-chitosan eye drops (experiment group) or ganciclovir eye drops (control group) in both eyes. The rabbit tears,corneas and aqueous humor were collected at different time for the determination of drug concentration by RP-HPLC. The pharmacokinetics parameters were calculated as well. RESULTS: In the experimenal group,the half-life(t1/2) in tears,corneas and aqueous humor were 15.41,45.21,59.43 minutes,respectively versus 16.22,32.55,and 48.53 minutes in the control group. The Cmax were 2.03 ?g?mL-1 and 1.22 ?g?mL-1,respectively. In the experimental group,the AUC0→240 in tears,corneas and aqueous humor were 1.66,1.89,and 2.77 times those in control group. CONCLUSION: The bioavailability of ganciclovir-chitosan eye drops was significantly higher than that of ganciclovir eye drops.

Objective Our study is to observe the effects of conjugated equine estrogen (CEE) combined with medroxyprogesterone acetate (MPA) on hemorheology in postmenopausal women in order to evaluate mechanism responsible for the increase in the incidence of cardiovascular disease after menopause and also to provide proper instruction and advice of hormone replacement therapy (HRT) for postmenopausal women Methods 60 healthy postmenopausal women were assigned to 3 groups randomly, 20 cases in each group Group A: CEE 0 625 mg/d+MPA 2 mg/d+calcium carbonate co. (Ca D) 600 mg/d Group B: CEE 0 3 mg/d+MPA 2 mg/d+Ca D 600 mg/d Group C: Ca D 600 mg/d only served as control Measurements of hemorheological parameters were performed before and 6 months after treatment Results After 6 months of HRT, group A: blood viscosity under the shear rate of 94 5 s -1 dropped from (5 23? 0 37) mPa?s to (5 03? 0 43) mPa?s ( P 0 05) Conclusion Both different dosages of CEE have favor effects on blood viscosity and erythrocyte deformabillity, which could play the role in preventing cardiovascular disease in postmenopausal women

Age-related macular degeneration ( AMD ) is a kind of age-related blinding degenerative fundus lesions, totally about 30 million patients suffering from AMD all over the world, with about 500 000 people blind for it yearly. As the development of economy and the aging of the population intensified, incidence of AMD indicates a trend of rising year by year, being the third major cause of blindness in our country. At present, the pathogenesis of AMD is not fully clear, as reported it may be related to oxidative stress, inflammatory immune response, VEGF and genetic manipulation. Clinical treatments mainly include photodynamic therapy, drug therapy, radiation therapy, laser photocoagulaory operation, the pupil warm treatments, Chinese medicine and intravitreous injection VEGF antagonists such as Ranibizumab, Conbercept and so on. ln this issue, we mainly expound on the progress in the epidemiological studies of AMD, especially elaborate the progress made on genetic manipulation in recent years.

All twenty seven patients suffered from Ⅱ grade spondilolisthesis were treated by posterior decompression, fixation with RF system and interbody fusion with TFC. One to three yearsafter operation, pain relief rate was 95%, lumbar fusion ratewas 95%,slip correction was 93.8%, and disc space was increased by 34%. It is concluded that this kind of operation can achieve satisfactory clinical results.

The kinase domain of receptor tyrosine kinase(RTK) ErbB2 was expressed fused with GFP in Pichia pastoris. Recombinant expression vector pPIC3.5K was constructed in Escherichia coli TOP10. The right P. pastoris transformants were screened on his-deficient plates and YPD-G418 plates by turns after electroporation of recombinant vector, and then induced by methanol in baffled shake bottles. The strain with highest protein yield was scaled up in a 5 L fermentor. Recombinant protein was analyzed with tyrosine kinase assay after Ni2+ affinity chromatograph. Results showed that the 100 kD recombinant protein with tyrosine kinase activity was successfully expressed in P. pastoris.

Marine actinomyces LYG-1 was isolated from marine mud flats in Lianyungang,China.Strain LYG-1 was identified using the methods of morphology,physiological and ehemotaxonomic characterization and 16S rRNA gene sequence analysis.The results showed that strain LYG-1 was a marine variable species of Streptomyces roseosporus.The fermentation broth of strain LYG-1 exhibited conspicuous antitumor activity against HepG2,MCF-7,HCT116 and MDA-MB-231 cell lines,and the IC50 values were defined by MTT method respectively.
