October 2011
Objective: To explore the clinical value of ultrasonic surface localization in internal jugular vein catheterization.
Methods: Totally 150 patients with American Society of Anesthesiologists physical status I -III who were planning to receive elective surgeries were randomized into anatomical landmark group, ultrasonic surface positioning group, and ultrasound-guided group using computed random table, with 50 cases in each group. The right internal jugular vein catheterization was performed after tracheal intubation.
Objective: To investigate the local cellular immune response after injection of superantigen, the highly agglutinative staphylococin (HAS), into the tumor bed after ultrasound-guided percutaneous microwave coagulation therapy (PMCT) in the liver cancer patients.
Methods: Ninety-two patients with pathologically proven primary liver cancer were divided into two groups: 45 in group A were treated by PMCT alone and 47 in the group B by combined with ultrasound-guided percutaneous injection of highly agglutinative staphylococin (HAS). Before and after PMCT and HAS treatment, the patients underwent ultrasound-guided percutaneous biopsy from the tumor bed and the samples were examined by pathology and immunohistochemistry.
Purpose: This study aims to analyze the long-term therapeutic results of small HCC less than 5 cm in diameter after microwave ablation (MA) or hepatic resection (HR) and choose factors that could predict metastasis and recurrence of small HCC.
Materials And Methods: The metastasis and recurrence of 194 patients with one HCC less than 5 cm in diameter who underwent curative HR or MA between January 1995 and December 2004 were reviewed retrospectively; immunohistochemistry was used to analyze the expressions of VEGF, bFGF, and c-Met in HCC tissues. Posttreatment prognostic factors were evaluated by multivariate analysis using Cox's proportional hazards model.
Article Synopsis
- The study aimed to compare the effects of percutaneous microwave ablation (PMA) and surgical resection on the dissemination of tumor cells in patients with small primary hepatocellular carcinoma (PHC) using AFP mRNA as a biomarker.
- Forty patients were involved, with blood samples taken before and after treatment to analyze liver function and immune response, revealing an increase in liver enzymes (ALT, AST) especially in the surgical group.
- Both treatments led to tumor cell dissemination into the blood, but no significant difference was found between PMA and surgical resection, with immune function showing a drop after surgery but staying stable in the PMA group.
Objective: To explore therapeutic results of local microwave ablation for hepatic metastasis and the factors influencing the survival after percutaneous microwave ablation therapy.
Methods: From July 1995 to June 2005 128 patients with 282 hepatic metastases nodules with the primary diseases of upper gastrointestinal tumor (n = 26), colorectal tumor (n = 44), breast carcinoma (n = 19), pulmonary carcinoma (n = 15), and malignant tumor in other part of the body (n = 24), underwent percutaneous microwave ablation therapy and were followed up for 29.7 +/- 19.
Objective: To evaluate the long-term results of percutaneous microwave coagulation therapy in the treatment of early hepatocellular carcinoma.
Methods: From May 1994 to June 2004, a total of 216 patients with 275 nodules of hepatocellular carcinoma whose diameter
Aim: The aims of this study were to explore individualized treatment method for hepatocellular carcinoma (HCC) patients whose maximum tumor size was less than 5 cm to improve prognosis and survival quality.
Methods: Thirty cases of primary HCC patients undergoing tumor resection were retrospectively analyzed (resection group). All the tumors were proved as primary HCC with pathologic examination.

November 2004
Objectives: To explore the effect of c-Myc, Ki-67, MMP-2 and VEGF expression on prognosis of hepatocellular carcinoma (HCC) patients who had tumor resection.
Methods: Primary HCC patients who underwent tumor resection were retrospectively analyzed. The maximum size of their mononodular tumors was less than 5 cm, and no intrahepatic arterial chemotherapy was performed before the resections.
[Ultrasound-guided percutaneous microwave coagulation therapy for hepatic metastases].

May 2004
Objective: To analyze the therapeutic results and prognostic factors of hepatic metastases treated by ultrasound-guided percutaneous microwave coagulation.
Methods: Seventy-four patients with 149 nodules of hepatic metastases were given percutaneous microwave coagulation therapy. The longest diameter of the metastatic nodule ranged from 0.
Aim: To explore the effect of c-myc, Ki-67, MMP-2 and VEGF expression on prognosis of hepatocellular carcinoma (HCC) patients undergoing tumor resection.
Methods: Primary HCC patients underwent tumor resection were retrospectively analysed. The maximum size of the tumor was less than 5 cm, there was only one nodule in each patient.
[Pathologic diagnoses of core needle biopsies of the mediastinum].
Zhonghua Bing Li Xue Za Zhi
April 2004
Objectives: To assess the diagnostic accuracy and to study the histologic typing of mediastinal lesions using core needle biopsies.
Methods: The histopathology and immunophenotype of 65 mediastinal core needle biopsy specimens were studied retrospectively by light microscopy and immunohistochemical staining (ABC method). Gene rearrangement studies were performed in some of the non-Hodgkin's lymphomas cases using PCR.
