[Impact of Light Polarization on the Measurement of Water Particulate Backscattering Coefficient].

Particulate backscattering coefficient is a main inherent optical properties (IOPs) of water, which is also a determining factor of ocean color and a basic parameter for inversion of satellite ocean color remote sensing. In-situ measurement with optical instruments is currently the main method for obtaining the particulate backscattering coefficient of water. Due to reflection and refraction by the mirrors in the instrument optical path, the emergent light source from the instrument may be partly polarized, thus to impact the measurement accuracy of water backscattering coefficient.

High-Frequency Observation of Water Spectrum and Its Application in Monitoring of Dynamic Variation of Suspended Materials in the Hangzhou Bay.

In situ measurement of water spectrum is the basis of the validation of the ocean color remote sensing. The traditional method to obtain the water spectrum is based on the shipboard measurement at limited stations, which is difficult to meet the requirement of validation of ocean color remote sensing in the highly dynamic coastal waters. To overcome this shortage, continuously observing systems of water spectrum have been developed in the world.

[Effect of Intestinal Ischemia-reperfusion Injury on the Expression of Chemerin in Mice].

Objective: To investigate the effect of intestinal ischemia-reperfusion on the protein expression of chemerin in C57BL/6J mice.

Methods: A total of 16 mice (C57BL/6J, specific pathogen free level) were randomly assigned into two groups (n=8 each): the intestinal ischemia-reperfusion group and the sham group. The intestinal ischemia-reperfusion state was achieved by blocking the super-mesenteric artery.

Serum thymidine kinase 1 levels correlate with clinical characteristics of esophageal squamous cell carcinoma.

Patients with esophageal cancer are often diagnosed at advanced stages, leading to poor prognosis. Biomarkers are needed to enable earlier detection as well as to aid in the prediction of prognosis, but to date these tools remain scarce. Thymidine kinase (TK1) has been shown to exhibit altered expression levels in esophageal tumor cells, therefore this study sought to determine whether serum TK1 levels are also altered and, if so, to assess the utility of TK1 as a biomarker in esophageal squamous cell carcinoma.

TLR4-HMGB1-, MyD88- and TRIF-dependent signaling in mouse intestinal ischemia/reperfusion injury.

Aim: To characterize high-mobility group protein 1-toll-like receptor 4 (HMGB1-TLR4) and downstream signaling pathways in intestinal ischemia/reperfusion (I/R) injury.

Methods: Forty specific-pathogen-free male C57BL/6 mice were randomly divided into five groups (n = 8 per group): sham, control, anti-HMGB1, anti-myeloid differentiation gene 88 (MyD88), and anti-translocating-chain-associating membrane protein (TRIF) antibody groups. Vehicle with the control IgG antibody, anti-HMGB1, anti-MyD88, or anti-TRIF antibodies (all 1 mg/kg, 0.

[The operative technique selection of lung transplantation for end-stage emphysema].

Objective: To investigate the operation of lung transplantation for end-stage emphysema.

Methods: From September 2002 to February 2005, 9 patients with chronic obstructive pulmonary disease (COPD) underwent lung transplantation. The types of surgery included single lung transplantation in 2 patients, lung transplantation with asynchronous contralateral lung volume reduction (one week later) in 1, single lung transplantation with synchronized contralateral lung volume reduction in 4, and bilateral sequential lung transplantation without cardiopulmonary bypass in 2.

[Single-lung transplantation and contralateral lung volume reduction for emphysema].

Objective: To report the operation technique, patient selection and curative effect of single-lung transplantation with contralateral lung volume reduction for a patient with end-stage emphysema.

Methods: A 47-year-old male patient who was dependent on mechanical ventilation because of end-stage emphysema received left-lung transplantation on 20 June, 2003. The surgical technique used was similar to that mentioned in the literature.

[Video-assisted thoracoscopic surgery for spontaneous pneumothorax].

Objective: To explore the operational procedures, indications, and the long-term results of video-assisted thoracoscopic surgery (VATS) in the treatment of spontaneous pneumothorax.

Methods: One hundred seventy three cases of spontaneous pneumothorax treated with VATS in our hospital between 1995 and 2001 were analyzed. Primary spontaneous pneumothorax (PSP) was found in 157 cases and secondary spontaneous pneumothorax (SSP) in 16 cases.

[Single-lung transplantation for end-stage emphysema].

Objective: To evaluate operative technique, patient selection and perioperative management of single-lung transplantation for a patients with end-stage emphysema.

Methods: A 56-year-old patient with end-stage emphysema underwent left-lung transplantation on September 28, 2002. The surgical technique used was similar to that mentioned in the literature.
