Chinese Journal of Postgraduates of Medicine 2008;31(21):20-22
Objective To investigate the role of various CA125 value in serum in instructing the treatment of endometrial cancer. Method The preoperative CA125 serum level of 147 cases of endometrisl cancer was examined by radioimmunoassay. Results Among patients with endometrial cancer, the CA125 level was higher in stages Ⅲ and Ⅳ than that in stages Ⅰ and Ⅱ (P<0.01). The sensitivity and specificity of CA125 > 20 kU/L in diagnosis of the endometrial cancer were 70.7% and 98.0%, and CA125 > 35 kU/L were 58.2% and 100.0%, respectively. The CA125 value of eases with cytological positive in abdomen was higher than that of cases with cytological negative. Conclusion The examination of CA125 serum level is valuable in the judgement of operative stages and lymph node metastasis in endometrial cancer.
2.Expression of angiopoietin-2 in esophageal squamous cell carcinoma and its significance
Cancer Research and Clinic 2014;26(3):172-174
Objective To analyze expression of angiopoietin-2 (Ang-2) protein in human esophageal squamous cell carcinoma (ESCC),and to investigate the relationship between Ang-2 protein and clinicopathologic factors.Methods 60 cases of ESCC,5 cases of latero-carcinoma tissues and 30 cases of normal tissue were immunohistochemically stained using Ang-2 monoclonal antibodies with PV-9000 non-biotin detection system.The positive expression rate and expression level of Ang-2 were evaluated.Results Ang-2 was mainly expressed in cytoplasm.The positive expression rates in normal epithelium,latero-carcinoma tissues and ESCC were respectively 3.33 % (1/30),40.00 % (2/5),53.33 % (32/60).Compared ESCC with normal epithelium and latero-carcinoma tissues,Ang-2 positive expression rate was significantly higher (P < 0.05).Among ESCC,expression of Ang-2 was positively correlated with the tumor infiltration depth (rs =0.621,P =0.002),and inversely correlated with tumor differentiation status (rs =-0.309,P =0.018).Conclusions Ang-2 may play an important role in the carcinogenesis and development of ESCC.Tumor differentiation degree,infiltration depth and TNM staging are the independent prognostic indicators for ESCC patients.Combinative detecting the expression of Ang-2 may provide more accurate information in early diagnosis and predicting the prognosis of ESCC.

Objective To evaluate the feasibility and effectiveness of percutaneous intraductal radiofrequency ablation (RFA) in treating biliary stent stenosis. Methods A total of 43 cases with biliary obstruction caused by biliary stent stenosis were enrolled in this study. Through percutaneous transhepatic pucturing of biliary duct, an EndoHPB catheter was placed in the stenotic site of the biliary stent, which was followed by RFA treatment. After RFA, biliary drainage catheter was reserved. The drainage catheter was removed when angiography confirmed that the stent was patent. Results Cholangiography showed that the biliary stent became patency after RFA in all patients. No procedure-related complications occurred. After RFA, the median patency time of the stenotic biliary stent in survival patients was 107 days (12-180 days). Conclusion The results of this preliminary clinical study indicate that percutaneous intraductal radiofrequency ablation has excellent effect and safety for the treatment of biliary stent stenosis, although more reliable and randomized controlled trials are needed before its effect and safety can be further proved.

Objective To evaluate the clinical and X-ray features of bone lesion in early congenital syphilis. Methods Between 1997 and 2005, 48 cases of early congenital syphilis were diagnosed. Among those 48 cases, there were 16 cases with bone lesions detected. The clinical and radiographic features of these 16 cases of bone lesion in early congenital syphilis were retrospectively analyzed. There were 10 males and 6 females with an age between 25-57 d. All patients were confirmed with serology and radiographs of limbs. They were given Penicilin G of 15-20 WU?kg-1?d-1, 3 times a day in a total of 14 days for one course of treatment. Results Rapid plasma reagent test(RPR) of all the cases was positive and they were 3 cases with 1∶128, 2 cases with 1∶64, 6 cases with 1∶32, 3 cases with 1∶16 and 2 cases with 1∶8. All the cases were positive for TPPA. 30 parents of 16 cases were tested for RPR and TPPA. The results showed that 16 mothers were positive for RPR, 13 fathers were positive for RPR. All the parents were positive for TPPA, and negative for HIV test. The main clinical features included active disorder, swelling of involved limbs, malnutrition, light body weight and multi-organ functional lesion. The main X-ray features were metaphysitis, periostitis and osteomyelitis involving all of the long bones of the extremities. Widen of the junction between epiphysis and diaphysis was the characteristic features of early congenital syphilis. After treatment, RPR became negative and sclerotic lesion was recovered and only remain periosteum proliferation. Hutchinson teeth were seen in some patients. Conclusion Bone lesions in early congenital syphilis has its characteristic clinical and radiographic features. The bone lesion could be cured after effective treatment.
