Objective By analysis oflateralepicondylitis patients MRI features to explore the lateralepicondylitis namedrationality and authorized its opinions for the ninth edition surgery textbook. Methods Cochrane's systematic review methods were used to retrieve the literature about lateralepi-condylitis patients MRI features fromCochrane Library, Medline, OVID, EMBASE, Chinese biomedical literature database (CBM), VIP, CNKI, Wan fang digital journals, and totally 31 articles were reviewed. 13 articles met the inclusion criteria for the lateral epicondyle of humerus elbow in patients with MRI findings. In accordance with the case-control data RevMan 5.0 software was used for Meta analysis withodds ratio (OR) as count data statistics. Interval estimation wasmade of 95% confidence interval (CI). When the datacannot be performed Meta analysis, only qualitative analysis was made. Results 13 studies met the inclusion criteria, including 315 ipsilateralelbows (5 patients with bilateral disease, 305 patients with unilateral disease) and 169 asymptomatic side of the elbow (98 cases of patients with the contralateral elbow, 71 cases of healthy volunteers). The results of Meta analysis suggested that pa-tients and healthy volunteers of elbow MRI showed statistically significance [OR=88.55, 95%CI=(29.20, 268.57)]. Between ipsilateral elbow and contra lateral of elbow MRI showed statistically significance [OR=80.17, 95%CI=(21.53, 298.59)]. MRI analysis showed that in addition to signs of extensor tendon injury, the elbow was also widely associated with other changes, such as radial collateral ligament in-jury, bone marrow edema, joint effusion, tendon tear, and elbows muscle edema. Conclusion Through MRI findings,the maln pathological changes of the so-called lateralepicondyliti-saremalnly for total ex-tensor tendon and adjacent tissue of chronic injury, Naming the current external humeral epicondylitis is unreasonable. Therefore, periarthritis of lateral epicondyle of humerus seems to be the best appropri-ate term to be usedwhenthe ninth edition surgery textbooksisauthorized.

Purpose:In order to improve the survival rate of recurrent ovarian carcinoma, influencing factors and the effects of combined therapy of recurrent epithelial ovarian carcinoma were investigated. Methods:From January 1998 to December 2000,60 patients with recurrent epithelial ovarian carcinoma were enrolled in the present study as research arm. The procedures of the combined treatment were as follows: After second cytoreductive surgery, platinum sensitive patients were treated with TP regimen (taxol+DDP) or CC regimen (CBP+CTX) and platinum resistant patients used TM regimen(taxol+MMC) or VM regimen(VP 16+MMC). Chemotherapy with 2/3 doses was continued after disease remission. Pelvic radiotherapy was performed for those with pelvic residual disease. IFN and/or IL 2 were administrated during chemotherapy and radiotherapy. 167 patients with recurrent epithelial ovarian carcinoma from January 1986 to December 1997, were retrospectively classified as control arm in this study. The patients were mainly treated with combined chemotherapy (CAP regimen) and traditional Chinese medicine applied as adjuvant therapy. Results:The rates of CR and PR in the research arm differed significantly from that in the control arm (43.33%, 45.00% vs. 2.99%, 7.78% P = 0.000). The 1 , 2 and 3 year survival rates of the research arm and control arm were 89.38%, 79.69%, 71.25% vs. 64.58%, 40.39%, 31.20% respectively ( P

Objective To investigate the effect of sodium fluoride(NaF) on proliferation, differentiation and the mRNA expression of osteoprotegerin (OPG) and receptor activator of nuclear factor κβ ligand (RAN KL) of mouse osteoblasts. Methods Osteoblasts were isolated from calvarias of Kunming mice born in 1 - 2 d and cultured. Various concentrations of NaF(0, 10-8, 10-7, 10-6, 10-5, 10-4, 10-3mol/L) were added to the culture medium, the proliferation and activity of alkaline phosphatase(ALP) was determined after 72 h or 120 h. The expression of OPG mRNA and RANKL mRNA was analyzed by semi-quantification RT-PCR. Difference among groups was analyzed by One-Way AN0VA. Difference between two groups was analyzed by LSD-t test. Results There was significant difference in cell proliferation among groups after 72 h(F = 13.806, P < 0.05). Compared with control group(0.434 ± 0.010) , the proliferation was significantly induced in 10-7 - 10-4 mol/L groups treated osteoblasts (0.448 ± 0.010, 0.453 ± 0.013, 0.454 ± 0.016, 0.449 ± 0.018, all P< 0.05), and was significantly suppressed in 10-3 mol/L group(0.401 ± 0.009, P < 0.05). There was statistic difference in the activity of ALP among groups(F = 9.021, P < 0.05). Compared with control group (1.677 ± 0.682), the activity of ALP significantly increased in 10-7 - 10-5 mol/L groups[ (2.447 ± 0.756) × 106, (2603 ± 0.183) × 106, (2.687 ± 0.886) × 106 U/L, P < 0.05 or P < 0.01 ] and significantly decreased in 10-4 mol/L group[ (1.479 ± 0.366) × 106 U/L, P < 0.05 ]. There was significant difference in the expression of OPG mRNA among groups(F = 11.299, P< 0.05). Compared with control group (1.000 ± 0.000), the expression of OPG mRNA was significantly increased in 10-7 - 10-4 mol/L groups( 1.058 ± 0.027, 1.053 ± 0.026, 1.088 ± 0.055, 1.069 ± 0.008, P < 0.05 or P < 0.01) , while significantly decreased in 10-3 mol/L group (0.941 ± 0.029, P< 0.05). There was no difference in RANKL mRNA expression among groups (F= 1.311, P> 0.05). The ratio of RANKL/OPG decreased with increasing doses of fluoride and increased in 10-4, 10-3 mol/L groups, but there was no difference between groups(F = 1.376, P> 0.05). Conclusions A biphasic pattern of proliferation and differentiation has been induced in mouse osteoblasts, which manifests stimulation effect in low doses and suppression in higher doses. Low doses of sodium fluoride suppress differentiation and maturation of osteoblasts by increasing expression of OPG mRNA, while high doses of sodium fluoride enhance differentiation and maturation of osteoblasts by decreasing expression of OPG mRNA.
