Purpose:In order to deterimine the role of CK7 and other monoclonal antibodies in identification of primary and metastatic malignant ascites due to ovarian carcinoma.Methods:We used immunocytochemical ABC assay to detect the experssions of CK7、MG7、CEA、AB、CK、CK8、EMA、HBME、LCA、VIM monoclonal antibodies in 43 ascitic samples and 22 specimens. Chi square was used for statistic assay with SPSS 8.0 software. Results:One way ANOV assay showed that: (1) Cytokeratin 7 monoclonal antibody can be a very useful mark of primary ovarian carcinoma. (2) MG7 expression in peritoneal cells was significantly different in primary ovarian cancer and metastatic ovarian carcinoma of gastric origin. (3) CEA can be helpful in suggesting the origin of intestine carcinoma or not. (4) Immunohistochemical study of the peritoneal fluids showed results, similar to those in specimens. Conclusions: Immunocytochemical assay in the peritoneal fluids is a helpful diagnostic modality in differentiating between primary and metastatic ascites due to ovarian carcinoma.

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 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.

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.

OBJECTIVETo observe the intervention of Shenkangling Decoction (SD) on the renal injury of primary nephrotic syndrome (PNS) children patients of Shen deficiency blood stasis syndrome (SDBSS) and to explore its mechanism.
METHODSTotally 65 PNS children patients were randomly assigned to the combined group (33 cases, treated by SD +Western medicine) and the Western medicine group (32 cases, treated by Western medicine). Meanwhile, 30 healthy children were recruited as the healthy control group from the medical examination center. Those in the Western medicine group were treated with prednisone (5 mg per tablet) at the daily dose of 1.5 -2.0 mg/kg till two weeks after their urine protein turned to negative. Then the dosage was reduced once daily per every other day. The therapeutic course lasted for more than 1 year. For those with no effect of prednisone or partial effect, cyclophosphamide intravenous pulse therapy was additionally applied for 2 successive days per week, a total of 6 times, or they took cyclosporine A. Patients in the combined group additionally took SD while starting treatment of prednisone. SD was decocted in water for oral dose, once daily, taken in two portions until 2 months after prednisone was discontinued. Efficacy was evaluated based on serum levels of chemotactic factor CXCL16, disintegrin metalloproteinase 10 ( ADAM10 ), disintegrin metalloproteinase 17 (ADAM17), albumin (ALB), total cholesterol (TC), and 24-h urine protein excretion (UPE) detected by ELISA before and after treatment.
RESULTSCompared with before treatment in the same group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE were significantly lower in the two treatment groups (P <0. 01). Compared with the control group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly increased, and the serum ALB level decreased in the two treatment groups (P <0.01). Compared with the Western medicine group at the same time point, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly decreased in the combined group. The 1 -year recurrence rate and the recurrence times decreased in the combined group (P <0.01). The complete remission rate increased in the combined group (P <0.01).
CONCLUSIONSD could effectively improve the clinical prognosis of PNS children patients possibly by reducing the release of inflammatory mediators such as CXCL16, ADAM10, and ADAM17, decreasing UPE and the TC level, and elevating the serum ALB level.

The study is aimed to understand the resource and the current situation of the use of Cibotii Rhizoma and provide the basis for protecting and utilization. The method of literature survey, field survey and quality assessment were applied in the study. The results showed that all the Cibotii Rhizoma came from wild resource and was mainly founded in Fujian, Guangxi, Guizhou, Yunnan, Guangdong, Hunan, Jiangxi, Sichuan, Chongqing, Zhejiang, etc. It contains over 5 000 000 kg in the area which total is about 7 000 hm2. The annual output is over 850 000 kg. At present, there is no cultivated resources. Based on the investigation and market sampling analysis from various regions, the results showed that the quality of the collected crude drugs conformed with the regulations of the Chinese pharmacopoeia. However the qualification rate of decoction pieces of Cibotii Rhizoma in market was only 56.4%. At present, the resource of Cibotii Rhizoma could meet the needs of medinal uses. It is important to protect the wild resource which is less and less because of the environmental factors. It also need to make a standard of processing method to ensure the safety, and solve quality problem of the decoction pieces.

OBJECTIVE:
To investigate the position change of the fibular bone after maxillary reconstruction by free fibular flap and to analyze the factors affecting the position change.
METHODS:
Patients who underwent maxillary reconstruction by free fibular flap in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from November 2012 to November 2016 were enrolled in this study. CT scans 1 week and 1 year postoperatively were collected and stored in DICOM format. The ProPlan CMF software was used to reconstruct the CT scans and separate the maxilla and each segment of the fibular flap. The Geomagic Control software was used to measure the long axis direction vector of each fibular segment. And the position change direction was recorded. The patients were divided into groups according to the use of the fibula or titanium plate to reconstruct the zygomaticmaxillary buttress.
RESULTS:
A total of 32 patients were enrolled. Among them, 21 were in the titanium plate group and 11 in the fibula bone group. The angle between the long axis of the fibular segment and the X axis in the X-Y plane was 95.65°±53.49° and 95.53°±52.77°, 1 week and 1 year postoperatively, and there was no statistical difference (P>0.05). The angle between the long axis of the fibular segment and the X axis in the X-Z plane was 96.88°±69.76° and 95.33°±67.42°, respectively, with statistical difference (P=0.0497). The angular changes of the long axis of the fibular segment in the titanium plate group and the fibular bone group were 3.23°±3.93° and 1.94°±1.78°, respectively, and the angular changes in the X-Z plane were 6.02°±9.89° and 3.27°±2.31°, respectively. There was no significant difference between the groups (P>0.05). The long axis changes of the fibular segment in the X-Y plane for reconstruction of the anterior alveolar, posterior alveolar, and buttress were 3.13°±3.78°, 2.56°±3.17°, and 5.51°±4.39°, respectively. There was a statistical difference (P = 0.023) between the posterior and buttress. In the X-Z plane, theses were 4.94°±4.75°, 5.26°±10.25°, 6.69°±6.52°, respectively. There was no statistical difference among the three groups (P>0.05). The main positional deviation directions of the titanium plate group and the fibular bone group were interior and superior sides, and there was no statistical difference between the two groups (P>0.05).
CONCLUSION
One year postoperatively, the position of the free fibular flap was changed compared with 1 week postoperatively. The position of the free fibular flap was mainly changed to the interior and superior sides.
