Purpose To explore the clinicopathologic characteristics, pathologic diagnosis and differential diagnosis of extraskeletal myxiod chondrosarcoma. Methods The clinical and pathological features were studied with HE and immunohistochemical staining in 5 cases of extraskeletal myxoid chondrosarcoma, and the related literatures were also reviewed. Results Extraskeletal myxoid chondro-sarcoma was male predominance (4 males: 1 female), and the age ranged from 32 to 62 years with an average of 52 years. Four tumors occurred in thigh and another in chest. Histologically, the neophlasm were composed of round and oval cells. Immunohisto-chemically, the tumor cells were positive for vimentin in five cases, synaptophysin expressed in one case, S-100 showed focal positivity in two cases, but negative for CK, p63, EMA, CD34, SMA in all cases. Molecular genetics detection shows chromosome exchange be-tween number 9 and 22. Conclusion Extraskeletal myxoid chondrosarcoma is a rare tumor which has no special characteristics in clinical and iconography, and its diagnosis mainly depends on the histopathologic features, immunohistochemistry and molecular genet-ics. Extraskeletal myxoid chondrosarcoma grows slowly, but have a high tendency for local recurrence and metastases.

Objective To evaluate the effects of combined treatment for advanced epithelial ovarian carcinoma and to analyze its prognostic factors Methods Fifty three patients treated with a three step combined therapeutic regimen were defined as research arm The procedures of the three step combined treatment were as follows: induction of tumor remission, sequential chemotherapy and adjuvant immunotherapy Three hundred and eighteen patients with advanced epithelial ovarian carcinoma treated with cytoreductive surgery and systemic chemotherapy were retrospectively classified into control arm Results The rates of complete response and partial response in the research arm were significantly differed from those in the control arm (90 6%, 5 7% Vs 70 1%, 5 3%, P

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

The present study aimed to investigate the clinical value of serum anti-mullerian hormone (AMH) and inhibin B (INHB) in predicting the ovarian response of patients with polyeystic ovary syndrome (PCOS).A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response:a low-response group (n=36),a normal-response group (n=44),and a high-response group (n=40).The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay (ELISA).The follicle stimulating hormone （FSH),luteinizing hormone (LH),and estradiol (E2) levels were determined by chemiluminescence microparticle immunoassay.The correlation of the serum AMH and INHB levels with other indicators was analyzed.A receiver operating characteristic (ROC) curve was established to analyze the prediction of ovarian response by AMH and INHB.The results showed that there were significant differences in age,body mass index (BMI),FSH,total gonadotropin-releasing hormone (GnRH),LH,E2,and antral follicle counts (AFCs) between the groups (P＜0.05).The serum AMH and INHB levels were increased significantly with the ovarian response of PCOS patients increasing (P＜0.05).The serum AMH and INHB levels were negatively correlated with the age,BMI,FSH level,Gn,and E2 levels (P＜0.05).They were positively correlated with the LH levels and AFCs (P＜0.05).ROC curve analysis of serum AMH and INHB in prediction of a low ovarian response showed that the area under the ROC curve (AUC) value of the serum AMH level was 0.817,with a cut-off value of 1.29 ng/mL.The sensitivity and specificity were 71.2％ and 79.6％,respectively.The AUC value of serum INHB was 0.674,with a cut-off value of 38.65 ng/mL,and the sensitivity and specificity were 50.7％ and 74.5％,respectively.ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response,the AUC value of the serum AMH level was 0.742,with a cut-off value of 2.84 ng/mL,and the sensitivity and specificity were 72.7％ and 65.9％,respectively;the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/mL,and the sensitivity and specificity were 76.3％ and 40.2％,respectively.It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS patients.

Background Currently,the recommendation when treating acute biliary or pancreatic disease during pregnancy is to perform endoscopic retrograde cholangiopancreatography (ERCP) without radiation exposure,either empirically (with no radiographic guidance) or with ultrasound guidance.However,few published studies compared these two ways.This study aimed to compare ultrasound-guided ERCP with the procedure without radiographic guidance in the treatment of acute pancreaticobiliary disease in pregnant patients.Methods The clinical data of 68 pregnant patients with acute pancreaticobiliary disease admitted to our hospital between January 2004 and May 2010 were reviewed retrospectively.ERCP was performed without radiographic guidance in 36 cases (group A) and with ultrasound guidance in 32 cases (group B).Data on the following variables were compared between the two groups:surgical success rate,rate of complete stone removal,time to resolution of clinical manifestations and laboratory indicators,length of hospital stay,complications,outcome and differences in efficacy of ERCP during different stages of pregnancy.Results In group A,the rates of surgical success and complete removal of stones were 69％ and 60％,respectively; the corresponding values were 91％ and 89％ in group B (P ＜0.05).Postoperatively,clinical manifestations improved rapidly in all patients; there was no statistically significant difference between the groups (P ＞0.05).Leukocyte counts and liver function had improved significantly after one week in all patients; they recovered more quickly in group B ((8.64±1.83)days vs.(14.57±3.74) days,(14.29±4.64) days vs.(20.00±5.40) days,P ＜0.01).The hospital stay was shorter in group B ((16.28±7.25) days vs.(28.00±6.83) days,P＜0.001).The complication rate was 14％ in group A and 3％ in group B (P ＜0.05).There were no significant differences between the two groups in the procedure's efficacy during different stages of pregnancy.Conclusions In the treatment of acute pancreaticobiliary disease during pregnancy,ultrasound-guided ERCP is safer and more effective than performing the procedure empirically without radiographic guidance when performed by experienced practitioners.Its more widespread use is recommended.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.
