By analyzing different cooperation modes in the pharmaceutical R&D and innovation between Hong Kong and Guangdong province, traditional cooperation mode and R&D outsourcing mode cannot adapt to the glob-al competition in modern pharmaceutical R&D and innovation field. The perfect cooperation mode is mainly through the mergers and acquisitions of large-scale enterprise groups, and joint ventures with research institutions, scientific research agency, and other corporate; through establishment of large pharmaceutical enterprise group be-tween the two regions; and through establishment of front shop-back factory mode. To effectively achieve this goal, Guangdong government should remove compartmentalization and multi-sectors management system in the pharmaceutical R&D and innovation system, promote mergers and acquisitions between pharmaceutical companies through capital market, and set up a pricing mechanism of pharmaceutical R&D and innovation for different prod-ucts and different development stage.

Matrix metalloproteinase-8 (MMP-8) is a collagen which belongs to matrix metalloproteinase.Its function is that degrades collagen and be involved in inflammation.In breast cancer,the level of expression of MMP-8 is related to the invasion and metastasis of breast cancer as well as the clinical and pathological stage of breast cancer,but it is unclear on the molecular mechanism of MMP-8 in the malignant tumor.The research of expression in breast cancer prognosis of breast cancer will provide a reliable assessment of molecular marker.

ObjectiveTo evaluate the clinical effect of artificial femoral head replacement in treatment of unstable intertrochanteric femoral fractures.MethodsThe clinical data of 52 unstable intertrochanteric femoral fractures patients with artificial femoral head replacement were retrospectivly analyzed.Postoperative complications and postoperative weight-bearing time were recorded.The function of joints was evaluated with Harris score.ResultsAll patients were followed up for 6 to 24 months ,an average of 13.2 months.1 case was a lung infection after surgery,and 3 cases were deep vein thrombosis.Weight-bearing walking time averaged 28 days.According to Harris score:25 cases were rated as excellent, 18 good,7 fair,2 poor.A total of 82.7％ of patients had their joint function returned to normal or near normal.ConclusionIt was an effective mothod to treat the unstable intertrochanteric fractures in elderly patients with hemiarthroplasty.

LI-cadherins are a new member of cadherin superfamily,which transmembrane glycoproteins mediate Ca2 + dependent cell-cell adhesion independent of cytoplasmic interactions.They play an pivotal role during tissue development and are critical for the maintenance of junctional complexes between cells and tissues,LI-cadherin high expression in hepatocellular carcinoma results in the decrease of intercellular adhesion effect,cause hepatocellular carcinoma metastasis.

Cyclophilin A（CyPA） is a cytoplasmic protein which binds to immunosuppressive drug—cyclosporin A and possesses peptidyl-prolyl cis-trans isomerase activity. CyPA incorporated into virions through interactions with the Gag polyprotein in the life cycle of human immunodeficiency virus type 1(HIV-1) and its incorporation is essential for viral infectivity. This review discussed the function of CyPA in replication of HIV-1 virion and the usefulness of these studies for anti-HIV therapies.

Objective To discuss clinical effect and clinical application value of lianqi capsules treated with the middle-late stage primary liver cancer. Method We choosed 168 cases of middle-late stage primary liver cancer patients in Guang'an District Hospital,Sichuan province,Guang'an treatment, and they were randomly divided into observation group and control group. Both two groups were treated with the same chemotherapy regimens. Pingxiaopian were auxiliarily used in control group, and lianqi capsules in observation group. Clinical curative effect and security of two groups were observed. Result There was no statistically significant difference between the total effective rate of clinical treatment group and control group. There were statistically significant differences between two groups on the quality of life period (P<0.05) and adverse reactions (P<0.05). Conclusion Lianqi capsules combined with chemotherapy was used in treatment of patients with locally advanced primary liver cancer, and it can effectively improve the patients’quality of life in the whole process, control the growth of the tumor, and increased synergistic effect of chemotherapy for patients. So Lianqi capsules was worthy in clinical application and popularization.

It is well known that adolescent varicocele is one reason to induce the testicular hypotrophy and potential infertility.Its indication and methods of treatment are controversial.This review provides the recent progress in diagnosis and treatment of adolescent varicocele including the indications and methods of surgical treatment,as well as new information of future researcher in the areas.

The myocardial cell respiration and the activity of pyruvic acid dehydrogenase system and glutathione peroxidase (GSH-px) in blood weredetermined in rats fed by deficient selenium (Se) diet, supplement Se dietand Xian diet. The absorbed oxygen value of myocardial cell respirationwas 52. 5 ? 3. 78, 69. 75 ? 5. 34, 77. 63 ? 4. 38 O ?l/40min/100mg myocardium(mean ? SE ) in deficient Se group, supplement group, and xian group, re-spectively. The difference between deficient Se group and supplement Segroup or Xian group was significant (P

OBJECTIVE:To establish a method for the determination of serum indapamide concentration.METHOD:10healthy male volunteers were assigned to receive7.5mg indapamide capsule on empty stomach with time-concentration de?termined by HPLC,and the pharmacokinetics parameters were accounted.RESULTS:C max was(0.212?0.167)mg/L,t max was(2.14?0.59)h,t 1/2 was(19.69?0.75)h,AUC 0～72 was(3.636?0.503)(mg?L)/h and AUC 0～∝ was(3.937?0.518)(mg?L)/h.CONCLUSION:The established method can be used for the clinical analysis on the use of indapamide and its pharmacokinetics study.

Objective To establish a method for content determination of hyodeoxycholic acid in Qingkailing Injection. Methods An UltimateXB-C18 column (5 ?m, 250 mm?4.6 mm) was used with a mobile phase of acetonitril-water-phosphoric acid (35∶65∶0.1). The flow rate was 1 mL/min. The temperature of the column was 40 ℃. The detection wavelength was 192 nm. Results There was a good linear relationship between the concentration of hyodeoxycholic acid and absorption area value in range of 0.201 35～1.006 75 mg/mL, r=0.999 6. The average recovery was 98.25% with RSD=1.26%. Conclusion This method was accurate, credible and repeatable which can be used to control the quality of Qingkailing Injection.
