Objetive: To study the effect of soybean isoflavone(SI) on the growth of gastric cancer cell SGC-7901 during hypoxia and its mechanisms. Method: The environment of hypoxia was established by GasPaK method. The effect of SI was determined by MTT and FCM which was used for studying apoptosis and cell cycle of SGC-7901. Electron microscopy was used to study the effects of SI on apoptosis and necrosis of SGC-7901. Cell-immunochemistry was used to observe the change of hypoxia-inducible factor HIF-1? and FAS expression. Results: SI could inhibit significantly the growth of SGC-7901, and arrest the cell in G2/M phases during normal and hypoxia environment. The inhibitory effect was elevated significantly during hypoxia. Electron microscopy showed the cell apoptosis and necrosis. FAS expression was elevated by SI during normal and hypoxia environment, and HIF-1? expression was downregulated during hypoxia. Conclusion: SI can inhibit SGC-7901 cell growth via arrest of cell cycle, elevated expression of FAS, apoptosis and necrosis induction and other pathways. The inhibition of the increased HIF-1? expression is probably the mechanism of the inhibitory effects of SI during hypoxia.

Objetive: To study the effect of genistein on the invasion and metastasis of human gastric cancer cells SGC-7901 in vitro. Method: MTT was used to study the effects of adhesion by genistein on SGC-7901. The Boyden Chamber membrane invasion culture system was used to study invasion and metastasis. Cell-immunochemistry was used to observe the change of TGF- 1. Results: In the membrane invasion culture system, the numbers of invading and migrating SGC-7901 cells were significantly lower in genistein treated groups than those in the control groups (P

In an uncertain and dynamic environment,medical research institutions must often balance between the usual medical research and emergent medical research.We interpreted this as a balance between exploitation-oriented innovation and exploration-oriented innovation.We pointed out that a flexible organization can coordinate the competition of scientific research resources between the two kinds of innovation; then we built an organizational flexibility model based on resource flexibility and coordination flexibility,and extended the model to medical research institution.And finally,we discussed the strategies for increasing organizational flexibility.

The technology role in diagnosing and treating gastroenterological of digestive endoscopy plays a significant diseases at present.The trainees for advance study are required to get familiar with the appliance,to learn about the indication,the contraindication,and the complication of using digestive endoscopy,to understand the advanced diagnosing and treating technology of digestive endoscopy in the world and they are also instructed without reservation the gist of endoscopic technique in accordance with their aptitude.

Military medicine has to restructure itself to meet military needs and e-Science patterns of the information age.This restructuration is known asinformationization of military medicine ( IMM).IMM is a process of vision refresh-ing into information thinking, mission expansion to the information field and paradigm shift to normal forms of information. The result is the emergence of military med-information technologies, military med-information research fields, and military med-informatics disciplines.

Objective To analyze the causes for the thigh pain after treatment of femoral trochanteric fractures by proximal femoral nail antirotation Ⅱ( PFNA Ⅱ) . Methods Included in this ret-rospective study were 236 patients who had been treated by us for femoral trochanteric fracture from October 2011 to December 2015. They were 103 men and 133 women, aged from 42 to 86 years (average, 50. 3 years) . According to AO classification, 13 cases belonged to type 31-A1. 2, 32 to type 31-A1. 3, 35 to type 31-A2. 1, 27 to type 31-A2. 2, 33 to type 31-A2. 3, 38 to type 31-A3. 1, 39 to type 31-A3. 2 and 19 to type 31-A3. 3. All the fractures were single, fresh and closed and treated with PFNAⅡinternal fixation. Results This cohort was followed up for 8 to 26 months (average, 13. 2 months). Nonunion occurred in one case who had to accept artificial hip replacement. The remaining 235 cases obtained bony union after 22 to 39 weeks (average, 29. 3 weeks). By the Harris evaluation at final follow-ups, the affected hips scored from 81 to 93 points (average, 85. 1 points) . Post-operative thigh pain was reported in 19 cases (8. 05％) . The causes included varied anatomic morphology of the proximal femur in 6 cases, distal defects of the intramadullary nails in 4, insufficient stability of internal fixation or uneven biomecanical distribution in 3, unskillful operation in 2, and severe oesteoporosis in 4. Avascular necrosis of femoral head was not observed during follow-ups. Conclusions Postoperative thigh pain is worthy of serious atention from orthopaedists following PFNA Ⅱtreatment of femoral trochanteric fractures. PFNA Ⅱshould be modified according to the specific Chinese features of the proximal femur, especially in the respects of anterior arch and distal structure of the main nail and lateral declination as well.

Objective To explore the role of the preoperative DSA examination and selected embolization in surgical treatment of intracranial huge meningiomas .Methods The clinical materials of 13 patients was collected and analyzed .Preoperative DSA was carried out in all cases ,10 of 13 underwent selected preoperative embolization ,the meningiomas were totally excised by surgery 4 to 7 days after the embolization .Results After the embolization ,DSA showed that the blood fed to the tumors was completely blocked in 8 cases ,and in great part in 2 cases .All tumors were totally removed ,the bleeding during operation was significantly decreased in patients who underwent preoperative embolization compared to the patients without embolization (P<0 .05) .Necrosis in different degree of meningiomas was found in postoperative pathological examination .There were no severe complications occurred during and after operations in all patients .Conclusion Preoperative selective embolization could significantly decrease the bleeding during operations .

Taking Science Citation Index Expanded (SCI-Expanded) as information source,and using methods of bibliometric analysis,Chinese Medicine international co-authored articles which published from 1998 to 2010 were statistically analyzed on publish year,document growth,active fields,etc.,aiming to look for status and trends in International Collaboration of the Traditional Chinese Medicine,and to be a reference for researchers.

This study was aimed to search and analyze patents of Chinese herb published both at home and abroad in 2010. The Derwent World Patents Index (DWPI) was used as database source. A total of 8 704 Chinese herb patent records were retrieved. And the geographical distribution was concentrated in China. The technological field was mainly on hepatitis, liver cirrhosis, lower back pain, cough and other diseases. Innovations on formulation and preparation method also required special attention. In addition, through the analysis on patent attribution agency, some well-known Chinese enterprises, who aim to gain the initiative in specific technical areas, have actively applied a number of patents in specific areas.

This survey included 59 secondary researches of traditional pharmaceutical patent literatures. The analysis was made on statistical indicator of the amount of annual papers, authors, institutions, published journals and re-search contents. The survey revealed that in the field of traditional Chinese medicine (TCM), the number of sec-ondary research of patent literature was on the increase, and the degree of concern of TCM patent was far more than others. This survey not only assisted the understanding of current condition of TCM patent literatures, but also held its development trend in order to apply it in the studies.
