Prenatal Diagnosis and Classification of Type I Persistent Left Superior Vena Cava.

Objective: This study aimed to assess the utility of two-dimensional (2D) ultrasonography in diagnosing and classifying fetal type I persistent left superior vena cava (PLSVC).

Methods: The diameter (D) of the coronary sinus (CS) was measured in the four-chamber view and the diameter (D) of the PLSVC was measured in the three-vessel trachea view; the ratio of the diameter of CS to PLSVC (D/D) and the ratio of gestational week (GA)/D and GA/D were calculated to analyze the correlation between measurement and classification of type I PLSVC.

Results: Compared the parameter of Ia and Ib Group, the differences in D, D, GA/D, and GA/D were statistically significant (P < .

Atmospheric transport and accumulation of organochlorine compounds on the southern slopes of the Himalayas, Nepal.

Studies have been devoted to the transport and accumulation of persistent organic pollutants (POPs) in mountain environments. The Himalayas have the widest altitude gradient of any mountain range, but few studies examining the environmental behavior of POPs have been performed in the Himalayas. In this study, air, soil, and leaf samples were collected along a transect on the southern slope of the Himalayas, Nepal (altitude: 135-5100 m).

[Expression and prognostic value of proliferating cell nuclear antigen in hepatocellular carcinoma patients received preoperative transcatheter arterial chemoembolization].

Background & Objective: Proliferating cell nuclear antigen (PCNA) could indicate cell proliferation of hepatocellular carcinoma (HCC), while the impact of preoperative transcatheter arterial chemoembolization (TACE) on cell proliferation of HCC is still uncertain. This study was to investigate the expression and prognostic value of PCNA in HCC patients underwent preoperative TACE.

Methods: The expression of PCNA in 91 specimens of HCC with preoperative TACE (TACE group) and 50 specimens of HCC without preoperative TACE (non-TACE group) was detected by immunohistochemistry.

[The value of TissueLink hemostatic sealer in hepatectomy for hepatocellular carcinoma].

Background & Objective: Managing the liver stumps reliably is an important guarantee for the accomplishment of hepatectomy. This study was to explore the value of TissueLink hemostatic sealer in hepatectomy for hepatocellular carcinoma (HCC), and evaluate its effects in extending incisal edge and reducing recurrence rate.

Methods: TissueLink hemostatic sealer was used on the liver stumps during hepatectomy for 20 patients (study group); whereas, conventional suturing of the vessels and bile ducts was performed in 28 patients (control group).

[Expression and clinical significance of VEGF and MMP-9 in hepatocellular carcinoma].

Background & Objective: Vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) are related to invasiveness, angiogenesis, and prognosis of malignancies. However, the reports on the results of VEGF and MMP-9 in estimating the prognosis of hepatocellular carcinoma (HCC) patients are different. This study was to investigate the expression and clinical value of VEGF and MMP-9 in HCC patients.
