Objective To explore the clinical value of combined detection of serum human epididymal secretory protein E4 (HF4) and CA125 in the diagnosis of endometrial carcinoma.Methods From Jan 2010 to Apr 2011,the serum specimens were collected from124 cases of endometrial carcinoma,97 cases of benign disease of uterus and 109 cases of healthy women.HE4 levels in the serum were detected by ELISA,and CA125 levels in the serum were detected by the electro- ehemiluminescent immunoassay.Those results were shown with median level.Accuracy of the diagnosis was evaluated by the area under the receiver operating characteristic curve ( ROC-AUC ).ResultsThe median levels of HE4 and CA125 were 78.09 pmol/L and 33.43 kU/L in serum of endometrial carcinoma group.The median levels of HE4 and CA125 were 46.37 pmol/L and 18.26 kU/L in serum of benign disease of uterus group.The median levels of HE4 and CA125 were 31.75 pmol/L and 12.64 kU/L in serum of healthy women group.The HE4 and CA125 levels in serum of endometrial carcinoma group were significantly higher than those of benign disease of uterus group or healthy women group ( all P ＜ 0.05 ).Compared with that benign disease of uterus group,the ROC-AUC of HE4 and CA125 in endometrial carcinoma group were 0.913 and 0.801,respectively.When the specificity was 95.0％,the sensitivities of HE4,CA125,and combined detection of HF4 and CA125 in endometrial carcinoma group were 41.1％,22.6％ and 46.0％,respectively.The positive rates of HE4 and CA125 were 31％ (27/86) and 12％ (10/86) in stage Ⅰ - Ⅱ of endometrial carcinoma,while the positive rates were 63％ (24/38) and 47％ (18/38) in stage Ⅲ -Ⅳ of endometrial carcinoma,in which there were significant difference between patients in stage Ⅲ - Ⅳ and stage Ⅰ - Ⅱ (P ＜ 0.01 ).ConclusionsThe combined detection of serum HE4 and CA125 is helpful to the diagnosis of endometrial carcinoma.The sensitivity,specificity and early diagnosis of HE4 are better than that of CA125.The positive rates of HF4 and CA125 in endometrial carcinoma are related to the clinical staging.

The serum specimens were collected from ovarian cancer (n =100),benign ovarian disease (n =69) and healthy women (n =95).The serum levels of HE4 and CA125 were detected.Risk of ovarian maliqnancy algorithm (ROMA) was calculated.Accuracy of prediction was evaluated by the area under receiver operating characteristic curve (ROC-AUC).And validity of prediction was evaluated by sensitivity and specificity.The results showed that the median level of ROMA algorithm was 83.0％,8.9％ and 8.7％ in ovarian cancer,benign ovarian disease and healthy women groups respectively.The difference were statistically significant (all P ＜ 0.01).Compared with benign ovarian disease group,the ROC-AUC of ROMA algorithm was 0.900 in ovarian cancer group.The sensitivity and specificity were 81.0％ and 92.8％ in ovarian cancer group respectively.Thus ROMA algorithm is a useful parameter in risk stratification for ovarian cancer.The diagnostic accuracy of ROMA algorithm is better than that of HE4 and CA125 in ovarian cancer.

Objective To study the relationship between the microvessel damage and the death rate of tumor cells and determine role of microvessel damage in the tumoricidal effect of hyperthermia.Methods H22 hepatoma cells were inoculated in the right hind legs of KM mice with immunosuppression.Local hyperthermia was administered to these mice which were divided randomly into 10 groups (8 in each group),which included groups of 3,6,12,24,48,72 and 96 h after hyperthermia for 30 min and groups of hyperthermia for 15,30 and 45 min.The tumor tissues were analyzed by flow cytometry(FCM)and immunohistochemistry.The cultured H22 cells were also given hyperthermia for 15,30,45 min and analyzed by FCM.Results The apoptotic rate(0.115±0.008)was higher in the initiation phase of hyperthermia in vitro,then the necrotic rates rose gradually.The difference between in vivo and in vitro was significant in hyperthermia of the same time about death rate(P＜0.05).A strong positive linear correlation(r=0.844)was observed between the death rate of tumor cells and MVD.Conclusion Microvessel damage plays the cardinal role in tumoricidal effect of hyperthermia.

Objective: To discuss the value of preserving ICBN during modified radical mastectomy for breast neoplasms. Methods: Sixty-three cases of breast carcinoma who underwent modified radical mastecto-my were studied. Of them, ICBN was completely preserved in 33 cases and was dissected in 30 cases. Sen-sory function of the medial upper arm of all patients was followed up after surgery. Results: No local recur-rence or metastasis was found among the 63 patients during the first, sixth, and twelveth month of follow-up period. Among the 33 cases with ICBN reserved, 29 cases (87.88%) had normal sensation of the skin in up-per medial arm and axilla, while 4 cases (12.12%) had paresthesia. Conclsion: Preserving ICBN can en-hance the quality of life of breast cancer patients after surgery.

AIM: There are many active components of tonifying kidney to strengthen the bone in Kanggu Zengsheng capsule, but there are few reports about its effect in treating bone fracture. CR molybdenum target X-ray is often used in mammary gland examination and disease diagnosis. This study detected the callus density during fracture healing in rats by CR molybdenum target X-ray to explore the promoting effects of Kanggu Zengsheng capsule on fracture healing. METHODS: The experiment was performed at the Laboratory Centre of Second Hospital of Hebei Medical University from July 2005 to March 2006. Sixty Wistar rats with an equal amount of males and females, 170-200 g, aged 9-10 months were randomly divided into experimental group and control group (n =30). After the tibial fracture model was made, the rats in the experimental group were given 1 mL Kanggu Zengsheng capsule suspension, 14.00-15.75 mg for each, once daily, while the rats in the control group orally took matching normal saline (9 g/L) once daily. All animals were executed under anesthesia by batch on the 3rd, 10th, 17th, 24th, and 33rd days after the operation, separately. The diameter of callus was measured with vernier caliper. The values of callus density were calculated by image analysis system in the CR molybdenum target X-ray. RESULTS: Sixty rats were all included in the final analysis. The photo of CR molybdenum target X-ray showed clear bone lines, and bone and soft tissue were evident. During the process of fracture union, there were significant differences in callus density between the two groups (P
