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 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 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.

Objective To explore the effect and mechanism of fragile site WWOX gene on regulating proliferation of gallbladder cancer cells in vitro. Methods The pcDNA3.0 - WWOX recombinant plasmid which was previous successfully built was transfected to GBC-SD cells and empty carrier by liposome medium. Liposome and GBC-SD were served as the negative control and the blank control,respectively. After 48 hours transfection, inverted microscope was used to observe the changes of gallbladder cancer cells' morphology,MTT and BrdU were used to detect the proliferation level of gallbladder cancer cells,and flow cytometry instrument was used to detect the change of the cell proliferation cycle. Results The results of inverted microscope shown: the number of GBC-SD cells in pcDNA3.0-WWOX group decreased significantly,the suspension cells and cell debris increased,while cells in the vector control,NC and Mock groups were in normal proliferation state. MTT test showed the proliferation levels of GBC-SD cells in pcDNA3.0-WWOX group was lower than those in the control group in 24 h,48 h,72 h,96 h and 120 h,and the differences were statistically significant(P < 0.05). The cell proliferation activity in the pcDNA3.0-WWOX group was obviously inhibited over time. BrdU detection results showed the cell proliferation rate of pcDNA3.0 - WWOX group was(0.44±0.03),while that in the three control groups was(0.78±0.02), (0.81±0.01)and(0.85±0.01),respectively. It showed that cell proliferation activity in pcDNA3.0-WWOX group was lower than the control groups,and the difference was statistically significant(P < 0.05). Cell cycle detection showed the cells increased in G0/G1 phase and decreased in G2/M and S phases of pcDNA3.0-WWOX group. The cell apoptosis rate was significantly higher and the proliferation index was significantly lower than those of the control groups(P < 0.05). However,there were no significant differences among the three control groups(P > 0.05). Conclusion The overexpression of WWOX gene in vitro could effectively inhibit the proliferation activity of gallbladder cancer cells. WWOX might participate in the development of the malignant biological behavior of gallbladder cancer cells. It is expected to become a new potential target for the gene therapy to gallbladder cancer.
