Objective To explore the possible effect of combined treatment of zoledronic acid and doxorubicin on proliferation,invasion and adhesion of SGC7901 cell line,and potential underlying mechanisms. Methods MTT and Transwell experiments were used respectively to investigate the effect of different concentrations of zoledronic acid and doxorubicin on the proliferation,adhesion and invasion of SGC7901. The mRNA levels of MMP2, TIMP2, MMP9, ICAM1 and CD44 were quantified by real time PCR. Results Gastric cell line SGC-7901 were incubated with zoledronic acid for 48 h in different concentration of 10-6,10-5,10-4,10-3 mol/L,their inhibition rates were 4.98%,12.19%,27.34% and 73.13% separately,which were higher than control group (P<0.01),and enhanced along with the dose increasing and the time extension (P<0.05).Gastric cell line SGC-7901 was incubated with zoledronic acid 10-4 mol /L and doxorubicin 0.5 mg/L,respectively,or in combination for 2 h,4 h,6 h,and thereafter,the detected adhesion rates were 5.03%,24.38% and 59.65% in control group,4.40%,19.77% and 51.22% in zoledronic acid group,4.28%, 18.62% and 51.02% in doxorubicin group,4.02 %,15.02% and 46.95% in combination group. The adhesion rates were reduced after incubation with different medicament concentration (P<0.05).In the study of cell invasion,the cell numbers per high power field were:105.11 ± 10.43,98.37 ± 15.75,96.19 ± 9.24,83.02 ± 19.72 after treatment with zoledronic acid,doxorubicin or their combination at different concentrations. Compared with control, signal medicament had weak effectiveness in invasiveness in SGC-7901 (P> 0.05),whereas in combination group it was significantly decreased (P<0.05).Both zoledronic acid and doxorubicin decreased the mRNA expressions of CD44,MMP2,MMP9,ICAM1 while increased TIMP2 mRNA level (P<0.05or P<0.01) versus control.The effect was more evident with combination treatment(P<0.05 or P<0.01),compared with doxorubicin group. Conclusions Both zoledronic acid and doxorubicin can inhibit the proliferation,adhesion and invasion of SGC7901. Combination treatment has additive effect.It may be related to the down-regulation of mRNA of ICAM1,MMP2,MMP9,CD44 and up-regulation of mRNA of TIMP2.

BACKGROUND:Currently, the morphologic changes of the discoid lateral meniscus (DLM) remain unclear, and morphological indexes used to evaluate the injuries of DLM stil need to be explored. OBJECTIVE:To compare the MR imaging difference between symptomatic and asymptomatic DLM in adults, and to select reliablemorphologicalparametersfor assessing DLM. METHODS:A total of 36 patients (36 knees) with a symptomatic DLM (study group)and 34 patients (34 knees) with an asymptomatic DLM (control group) were included in this study. GE Healthcare Centricity RIS/PACKS System was used to measure the primary morphological parameters of two patients with DLM on coronal MR imaging. Intergroup comparison was performed with the Wilcoxon test. RESULTS AND CONCLUSION:On the coronal MR imaging, the width of the body portion and height of the free edge of the DLM was significantly increased in the study group compared with the control group (P< 0.001), while the height of the peripheral portion which connects with the capsule of the DLM was significantly decreased in the study group compared with the control group (P= 0.002). The heightof the middle of the DLM and the width of the lateral femoral condyle showed no significant differences between the both groups (P> 0.05). The width ratio of the body of the DLM to the lateral femoral condyle and the height ratio of height of the free edge to the middle of the DLM were significantly increased in thestudy group compared with the control group (P< 0.001), while the height ratio of the peripheral portion to the middle for the DLM was significantly decreased compared with the control group (P< 0.001). These findings suggest that compared with asymptomatic discoid lateral meniscus, the width of the body portion and the height of the free edge for the DLM are increased;however,the height of the peripheral portion which connects with the capsule of the DLM is decreased. The width ratio of the body portion of the DLM to the lateral femoral condyle and the height ratio of the free edge to the middle for the DLM may be reliable morphological parameters for the assessment of the DLM in adults.

OBJECTIVETo explore rest, cold compress and elevate (RICE) with rest, compress and elevate (RCE) without cold for the treatment of acute ankle sprain, in order to clear mid-term clinical effects.
METHODSEighty-nine patients with acute ankle sprains were collected from January 2013 to March 2014,including 30 males and 59 females aged from 18 to 60 years old with an average of 36 years old; the time from injury to hospital ranged from 3 to 24 h with an average of 9 h. All patients were divided into two groups according to visiting sequence. There were 45 patients in RICE group, and 45 patients in RCE groups. The main therapeutic effect index was evaluated by Karlsson scoring, and secondary therapeutic effect index was pain and satisfactory VAS scores. Safety index evaluated by adverse event.
RESULTSOn the 2nd weeks after injury, Karlsson score in RICE group was 44.66 ± 11.58, and 46.67 ± 8.52 in RCE group, while there was no statistical significance between two groups in Karlsson scores (P > 0.05). Karlsson score of two groups after treatment were higher than before treatment. There was no significantly meaning in pain and satisfactory VAS scores between two groups (P > 0.05). No adverse reaction were occurred between two groups.
CONCLUSIONCold compress did not receive much more final gains, and no evidence showed cold compress could affect recovery of joint function.
