Objective To evaluate the effect and mechanism of ginseng polysaccharides injective solu-tion on invasive ability of human breast cancer MCF-7 cells.Methods Human breast cancer MCF-7 cells were treated with different concentrations of ginseng polysaccharides injections(12.5μL/mL,25μL/mL,50μL/mL or 100μL/mL),and phosphate buffer saline was served as control.The invasive ability,transfer ability and protein expression of matrix metalloproteinases-2 ( MMP-2 ) and matrix metalloproteinases-9 ( MMP-9 ) were determined via transwell matrigel invasive test,scratch test and Western Blot,respectively.Results Ginseng pol-ysaccharide injection on invasive ability and transfer ability in vitro of MCF-7 cell had significant role in inhibi-ting effect,and showed dose and time dependent.After ginseng polysaccharides injection treatment,the MMP-2 and MMP-9 protein expression significantly reduced,and showed dose and time dependent manner.Conclusion Ginseng polysaccharides injection is able to inhibit the invasion and transfer in MCF -7 cells.Moreover,theregulation of MMP -2 and MMP -9 expression may be involved in this effect.

Conotruncal defects(CTD) is a kind of severe cardiovascular abnormality, which is the major cause of death in rinatal pelriod. Some researches suggest that CTD and 22q11 microdeletion had close relationship. In addition, HIRA gene is located in 22q11, which was speculated as a candidate gene in CTD.

High intensity focused ultrasound(HIFU) is a technique that ultrasound energy is focused on tumor target to function the treatment through the biological effects including heating effect, cavitation effect and mechanical effect of body to caused cell coagulation necrosis in vivo. Ultrasound contrast agent is one of the most important applicational agent for the treatment of hepatocellular carcinoma(HCC). We discussed in this paper the application of ultrasound contrast agent in the diagnose and focusing of target before the treatment and the assesement of treatment of HCC. Considering the enhancement of cavitation effect, better acoustic environment that enhance biological efficacy of HIFU during the treatment of HCC, ultrasound contrast agent is drawing more attention as an HIFU enhancement agent.

Objective To improve the understanding of medical literature databases in order to correctly select and use them. Methods The use of 4 common medical literature databases in China was comparatively analyzed. Re-sults Repetitive and incomplete literature coverage, imperfect key retrieval techniques, insufficient retrieval func-tions, loose design, and unscientific retrieval systems were the major problems of the 4 commonly used Chinese medical literature databases. Conclusion The user should know the weak points of different databases and selectively use them. Standardization and quality control of medical literature databases should be further improved.

Objective To discuss clinical results of self-made anatomical dynamic hip lock plate (ADHLP) in treatment of intertrochanteric fractures. Methods ADHLP was applied in 73 patients in-eluding 52 males and 21 females at age range of 19-92 years ( mean 54.7 years). Fractures were caused by traffic accidents in 32 patients, sllp in 21, fall from height in nine and other factors in 11. According to the Evans' s classification system, there were 42 patients with type Ⅰ fractures, 17 with type Ⅱ, nine with type Ⅲ and five with type Ⅳ. Self-made ADHLP was applied to manage various fractures with differ-ent operation strategies. The curative effect of ADHLP was observed for evaluation of ADHLP. Results The operation lasted for mean 60 minutes (40-90 minutes). The volume of blood loss was mean 200 ml (100-400 ml). All patients were followed up for 6-48 months (average 36 months), which showed that the function of hips was satisfactory, with excellence rate of 99%. There were no complications like coxa yam, femoral head eoncis, rotation displacement, iatrogenic fracture, infection or internal fixation break and loosening. Conclusions ADHLP takes advantages of reasonable vitodynamics, wide operation in-dicatioas, convenient operation, minor trauma, fast recovery, stable fixation and few complications for in-tertrochantefie fractures, especial]y osteoporotie and gemntal patients.

AIM: To compare the difference of A-scan and lOL Master in intraocular lens power measurement.
●METHODS:Two hundred and twenty-six patients (230 eyes) with age-related cataract were included in the study. Before surgery, axial length was measured by A-scan and lOL Master respectively and corneal curvature was measured by auto refractometer. lntraocular lens power was calculated according to the SRK-T formula. Corneal curvature was measured by auto refractometer and the refractive outcome was performed by phoropter three months after cataract surgery.
●RESULTS:The mean axial length was (23. 48 ± 1. 94) mm measured by A-scan and (23. 75±1. 96) mm measured by lOL Master. There was significant difference between them ( P < 0. 05 ). After random grouping, the preoperative and postoperative mean corneal curvature in A-scan group was (43. 94±1. 81) D and (43. 98±1. 87) D respectively. There was no statistically significant difference between them (P>0. 05). And the results were (44. 10 ± 1. 57 ) D and ( 44. 11 ± 1. 58 ) D in lOL Master group. There was no significant difference between them (P>0. 05); The mean absolute refractive error (MAE) in A-scan group was ( 0. 47 ± 0. 27 ) D and in lOL Master group (0. 41±0. 19) D. The difference was significant (P<0. 05).
●CONCLUSION: lOL Master is proved to be slightly more accurate than A-scan for lOL power calculation.

Objective To discovery the difference about TCM constitution between urban and rural area from the survey results performed in 2 communities of Beijing. Methods 9 standard survey scales of Chinese Medicine Constitution and four diagnostic methods of TCM were performed to identify body constitution of 161 people whose age are almost 64 years; The distribution of total constitution and the constitution distribution of same sex were further analyzed. Results The distribution of 9 TCM body constitution were different between town and country, the gentleness type distribution in country was lower than city (24.68%, 51.19%) ; Qi-depression type distribution was significant higher in country than city (44.16%,5.95%) . Conclusion Most of people in the country were yang-deficiency type and qi-depression type body constitution, the distribution of which affected by gender and age, etc.
