BACKGROUND:In vitro and in vivo studies of cel response to a variety of mechanical loadings have demonstrated the stimulation of bone formation by loads. However, the effects of different mechanical strains on the same cel s have never been adequately studied by far.
OBJECTIVE:To investigate the effects of different mechanical strains on rat bone marrow mesenchymal stem cel s.
METHODS:Rat bone marrow mesenchymal stem cel s were isolated and cultured in vitro. Bone marrow mesenchymal stem cel s were subjected to different stimulations including dynamic stretch, static stretch and hybrid stretch through the use of custom-made mechanical stretch device. Cel ular proliferation, alkaline phosphatase activity and mRNA expression of Runx2 of bone marrow mesenchymal stem cel s were detected and the secretion of osteocalcin was evaluated under three different stretch modes respectively.
RESULTS AND CONCLUSION:Compared to the control group, cel proliferation increased by 18.67%, however, alkaline phosphatase activity, Runx2 expression and osteocalcin secretion were not changed obviously in the static stretchgroup. Compared to the control group, alkaline phosphatase activity, Runx2 expression and osteocalcin secretion increased by 60.33%, 49.67%and 48%respectively;however, cel proliferation was inhibited, in the dynamic stretch group. Compared to the control group, cel proliferation was slightly, but not significantly, increased in the hybrid stretch group, and the alkaline phosphatase activity, Runx2 expression and osteocalcin secretion increased although the increases were not as apparent as those in the dynamic stretch group. These findings suggest that static mechanical strain can significantly promote cel proliferation, the dynamic mechanical strain more greatly promotes osteogenic differentiation of bone marrow mesenchymal stem cel s, and the hybrid mechanical strain promotes the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cel s.

Objective To investigate paclitaxel and ezrin-siRNA therapy for metastatic liver cancer.Methods Human metastatic liver cancer cells MHCC97-H were divided into four groups in vitro and in vivo,including control cells,exposure to paclitaxel alone,ezrin-siRNA alone,and the combination of paclitaxel and ezrin-siRNA.Nude mice lung lesions were formed by tail vein injection of tumor cells.The tumor cells'apoptosis rate,wound healing ability,the ability to cross an artificial membrane,and the numbers of metastatic lung lesions were measured.Results The apoptosis rate in normally cultured MHCC97-H tumor cells was 2.52％,compared to the other three groups at 11.66％,2.35％,7.38％ respectively.The wound healing ability was best in the negative control and weakest in cells treated with combination paclitaxel and ezrin-siRNA.The numbers of cells which could cross the artificial membrane in the negative,paclitaxel,ezrin-siRNA,and combination paclitaxel and ezrin-siRNA group were 52.5 ± 3.9,32.2 ± 3.2,26.6 ± 2.4,and 19.4 ± 1.1 respectively.The numbers of metastatic lung lesions in the nude mice (n =40) were 12.5 ±2.4,8.2 ± 1.5,7.0 ± 1.3,and 3.8 ± 0.3 respectively.Conclusions The ezrin-siRNA combined with paclitaxel therapy demonstrated a greater efficacy over single agent therapy for depressing liver cancer growth,motility,aggression,and metastasis in vitro and in vivo.

Objective To find out whether the benefits entitled to peasants have increased since NRCM is in place in Beijing, and to analyze the extent of such benefit increase if any. Methods The first is to calculate changes to the reimbursement ratio of hospitalization charges for the peasants covered by NRCM; the second is to calculate the role played by NRCM for alleviating the catastrophic health expenditure of peasants. Results The reimbursement ratio of hospitalization charges for peasants covered by NRCM rose from 32.4% in 2004 to 45.4% in 2007. Survey data from districts and counties in the sampling test indicate that NRCM has gained an ever growing power in alleviating the catastrophic expenditure of peasants. Conclusion Recent years have witnessed a marked growth in medical charges, peasants' income, and peasants' demand for medical services. Against such a background, NRCM can still sharply downsize their catastrophic health expenditure, and its role keeps intensifying. This proves that the fund raising speed of NRCM has greatly outpaced the growth of medical charges and peasants' demand for medical services, and NRCM is playing a more effective role in alleviating the peasants from poverty caused by diseases.

Objective Via targeted inhibition of oncogene Bmi-1 expression by RNAi interfering technology in vitro, to observe its effect on the proliferation and cell cycle of gallbladder cancer cells. Methods Four miRNABmi-1 recombinant plasmids were constructed according to different Bmi-1 sites. RT-PCR and Western blot were used to mRNA and protein expression of Bmi-1 in gallbladder cancer cells were measured by RT-PCR and Western blot. mRNA and protein expression of Bmi-1 in gallbladder cancer cells. The most effective interfering plasmids in the miRNABmi-1 groups were transfected into GBC-SD cells. Cell proliferation and cell cycle were analyzed 48 h after transfection by BrdU and flow cytometry. Results Bmi-1mRNA expression in miRNAbmi1-1,-3 and-4 was significantly lower than the control group (P<0.05);and Bmi-1 protein expression in miRNAbmi1-2,-3 and-4 was significantly lower than the control group (P<0.05). The recombinant plasmid in miRNAbmi1-4, with the strongest inhibitive effect of Bmi-1mRNA and protein expression, was transfected into GBC-SD cells,then the cell proliferation rate (46.63 ± 5.31) was significantly lower in mRNABmi1-4 group than the control groups (P<0.05);G0/G1 phase cells increased (72.20 ± 1.71) and G2/M and S phase cells decreased (18.30 ± 7.21, 9.50 ± 6.01) in miRNABmi1-4 group. Both were significantly different from the control groups (P<0.05). Conclusions Targeting and silencing Bmi-1 expression can effectively inhibit the proliferation of GBC-SD cells and restrain the cell cycle atin G0/G1 phase. Bmi-1 gene may be a novel target for geneic therapy of gallbladder carcinoma.

Objective To investigate the diagnosis and surgical treatment of chronic acalculous cholecystitis characterized by absence of gallbladder wall contractability. Methods The clinical data of 42 patients with chronic acalculous cholecystitis in our hospital from January 2006 to December 2008were analysed. The patients were grouped into two groups: laparoscopic cholecystectomy (LC) group in 20 and non-surgical group in 22. The patients' symptoms on follow-up in the two groups were compared. Results The 42 patients with chronic acalculous cholecystitis were diagnosed by symptoms,ultrasound, fatty meal gallbladder contractability studies under ultrasound, fiber optic gastroscopy and magnetic resonance cholangiopancreatography (MRCP). In all patients, there was a complete absence of gallbladder wall contractability. In the LC groups, 20 patients received LC. 18 patients were followed up, and there were no symptoms. Two patients were lost to follow up. In the non-surgical group, 22 patients received non-surgical treatment. In 21 patients who were followed up, 19 patients had symptoms. One patient was lost to follow up. There was a significant difference between the LC group and the non-surgical group (P＜0.05). Conclusions Chronic acalculous cholecystitis characterized by absence of gallbladder wall contractability could be diagnosed by symptoms, ultrasound, fatty meal gallbladder contractability studies under untrasound, and MRCP. The optimal treatment of chronic acalculous cholecystitis characterized by absence of gallbladder wall contractability is LC.
