OBJECTIVE:To provide reference for the development of online drugstores in China based on mobile port. METH-ODS:The development of online drugstores in China based on mobile port was analyzed by SWOT(strengths,weaknesses,oppor-tunities,threats)analysis to put forward suggestions. RESULTS & CONCLUSIONS:Online drugstores based mobile port included vertical management in which pharmaceutical E-commerce manager directly participate,non-vertical management which mainly pro-vide information inquiry and price comparison. It has advantage in breaking through time and space obstacle,optimizing informa-tion display,integrating consumer’s information accurately,improving human efficiency,etc. They are weak in timeliness,busi-ness scope and sale function,the quality of pharmaceutical care,user activity,etc. They have the opportunities as annual increase of mobile E-commerce market scale and huge market development potential;they also face various threats,such as the inconformi-ty between main users of mobile port and main purchasers,consumer low-trust,health-care polity barrier breakthrough failure,the lack of legal regulations for medical and pharmaceutical software,etc. It is suggested that companies operate further accurately and the government speed up the formulation and implementation of laws and regulations.

BACKGROUND:The studies about biomechanics of total knee arthroplasty were more, but the research on finite element analysis of the effect of total knee arthroplasty on proximal tibial reconstruction was not much.
OBJECTIVE:To study the effect of total knee arthroplasty on proximal tibial reconstruction using finite element analysis.
METHODS:We designed knee models of two materials:one was functional y graded material models of col agen and titanium composite materials;another was titanium al oy material model. We created two prosthesis material tibia-knee prosthesis model, and analyzed bone density distribution of proximal tibia, the maximum stress value of the medial tibia and the lateral tibia, and the maximum stress value of medial tibia and prosthesis junction, as wel as lateral tibia and prosthesis junction after knee arthroplasty.
RESULTS AND CONCLUSION:(1) Bone density of proximal tibia after total knee arthroplasty:The bone density of the knee prosthesis handle with medial and lateral tibia at the junction of tibial plateau was decreased than that of the initial state. Stress shielding effect was lower in col agen and titanium composite materials of functional y graded material models than that of titanium al oy material model. The bone density of shank end of the tibial prosthesis was obviously increased compared with the medial and lateral tibia, showing stress concentration. (2) The maximum stress value of the medial and the lateral tibia:The maximum stress value of the medial and the lateral tibia in col agen and titanium composite models was lower than that of titanium al oy material model. The maximum stress values of the lateral tibia of col agen and titanium composite models and titanium al oy material model were lower than that of medial tibia. (3) The maximum stress of medial tibia, lateral tibia and prosthesis junction:The stress distribution of col agen and titanium composite models was relatively uniform. The stress distribution of titanium al oy material model showed fluctuation. Stress concentration appeared in pal ets and prosthesis junction and the shank end of the prosthesis. The maximum stress values of lateral tibia and prosthesis junction of col agen and titanium composite models and titanium al oy material model were lower than that of medial tibia and prosthesis junction. (4) These findings showed that knee prosthesis has a certain stress shielding effect on tibia after total knee arthroplasty. The stress shielding effect of col agen and titanium composite material prosthesis was lower than titanium al oy material prosthesis, and could improve tibial incurred stress.

Objective: To investigate the inhibition of luteoloside on the proliferation of human esophageal carcinoma cell line Eca109 and its mechanism. Methods: MTT assay was used for detecting the influence of luteoloside at different concentration on the proliferation of Eca109. The morphological changes of cells were observed under inverted microscope. The cell cycle and apoptosis were detected by flow cytometry. RT-PCR was used to detect the mRNA expression of cyclin D1, survivin, and c-myc genes. Results: The results of MTT assay showed different doses (80, 120, 160, 200, and 240 μmol/L) of luteoloside could inhibit the cell proliferation of Eca109 cells in a dose-response manner. Luteoloside could also change the morphological characteristics of cells, reduce the cell size, and separate from peripheral cells. Treated with 240 μmol/L luteoloside, the cells were sprouting and some of them developed multiple pseudopodia-like protrusions. Treated with luteoloside (160 and 240 μmol/L), the cell cycle of Eca109 cells was blocked in G2/M phase and apoptosis was induced (P < 0.05). Compared with the control group, the gene expression of cyclin D1, survivin, and c-myc was decreased after treated with 240 μmol/L luteoloside for 48 h (P < 0.05). Conclusion: Luteoloside could significantly inhibit the proliferation of Eca109 cells by changing the cell cycle and inducing the apoptosis. Moreover, it could decrease the mRNA expression of relative genes.

Objective To observe the recovery efficiency of sufentanil and oxycodone hydrochloride in neurosurgical operation.Methods Total of 120 patients scheduled for microvascular decompression under general anesthesia were randomly divided into 4 groups to receive 0.03 mg·kg-1 oxycodone (group H1), 0.05 mg·kg-1 oxycodone (group H2), 0.08 mg·kg-1 oxycodone (group H3), and 0.08 μg·kg-1 sufentanil (group S).Each patient accepted 4 ng·mL-1 of remifentanil and 5-6 mg·kg-1·h-1 of propofol after induction to maintain bispectral index (BIS) value at 40-60.On starting to suture dura mater, oxycodone or sufentanil was given in various doses through intravenous route.The BIS value, the amount consumption of propofol, anesthesia and operation duration, and the drug delivery time of each group were recorded.The time of spontaneous breath recovery, awaking and extubation, verbal rating score (VRS) and sedation score (SS) at 10 min, 20 min, 30 min after operation as well as side-effects were also recorded.Results The VRS scores had no statistic difference among the groups at 10 min after operation, while the average scores of H1 were higher than those of H2 and H3 at 20, 30 min after operation.No statistic difference of the SS scores was showed among 4 groups at 10 min after operation, but it was lower in group H1 than those in group H3, and lower in group S than those in H2 at 20 min after operation;group H3 had a significantly higher SS scores than H1, H2 and S at 30 min after operation.Conclusion Oycodone hydrochloride 0.05 mg·kg-1 or sufentanil 0.08 μg·kg-1 can both provide satisfactory recovery quality in neurosurgical operation.

Ten novel conjugates with ursolic acid core and different chalcone ligands were synthesized via esteri-fication using the natural ursolic acid as starting material. The structures of these conjugates were confirmed by 1 H NMR, 13 C NMR and HRMS. The preliminary biological results showed that these compounds displayed signifi-cant antiproliferative effect on CNE2, KB, MCF-7, A549 and HepG2 cells. These compounds were more effective than ursolic acid and tamoxifen against MCF-7 cells. Especifically, compound 11e ( IC50 =4. 7 μmol/L) showed the greatest potency against MCF-7, which was about 3-times more potent than tamosifen ( IC50 =15. 2 μmol/L) . Additionally, all conjugates were nontoxic to health MCF-10A and VERO cells, and had higher security than tamoxifen.
