Post-traumatic stress disorder after typhoon disaster and its correlation with platelet 5-HT concentrations.

Objective: To investigate residents' psychological stress factors and research the correlation between post-traumatic stress disorder (PTSD) and platelet 5-HT concentrations so as to provide scientific bases for diagnosis and treatment of PTSD and psychological intervention for people in the disaster area.

Methods: A questionnaire survey of 5500 residents who have accepted psychological help was conducted by the emphatic investigation method. While high performance liquid chromatography was used to detect the platelet serotonin concentration of 100 PTSD patients and 100 healthy people.

Nicorandil protects against ischaemia-reperfusion injury in newborn rat kidney.

Ischaemia-reperfusion injury (IRI) is the predominant cause of acute kidney injury. Nevertheless, the underlying molecular mechanisms are still unclear. The current study investigated the effects of nicorandil on ATP-sensitive potassium (KATP) channels and the potential signal transduction pathway(s) in a rat kidney IRI model and in cultured tubular HK-2 cells subjected to oxygen and glucose deprivation/reoxygenation (OGD/R) injury.

Activation of integrin β1-focal adhesion kinase-RasGTP pathway plays a critical role in TGF beta1-induced podocyte injury.

The depletion of glomerular podocytes is the key mechanism of glomerulosclerosis and progressive renal failure. Transforming growth factor-β (TGFβ) is a central mediator of signaling networks that control a diverse set of cellular processes, such as cell proliferation, differentiation, and apoptosis. Though many key events in TGFβ1 signaling have been documented at cellular and molecular level in podocytes, the complete effects of TGFβ1 on podocyte integrity are still elusive.

Multislice spiral computed tomography imaging in congenital inner ear malformations.

Objective: The purpose of this study is to evaluate the usefulness of multislice spiral computed tomography (CT) in the diagnosis of congenital inner ear malformations.

Methods: Forty-four patients with sensorineural hearing loss were examined on a Somatom Sensation 16 (Siemens) CT scanner. The 3-dimensional reconstructions and multiplanar reformation (MPR) were performed using the volume-rendering technique (VRT) on the workstation.

Findings of chest radiograph and spiral computed tomography in Swyer-James syndrome.

Objective: To evaluate the value of X-ray and spiral computed tomography (SCT) in the diagnosis of Swyer-James syndrome (SJS).

Methods: A total of 28 patients, 12 males and 16 females, were studied retrospectively. Ages ranged from 11 to 57 years, the mean age was 32 years.

[Multi-slice spiral CT imaging in the post-operative assessment of cochlear implanted electrode].

Objective: To evaluate the usefulness of multi-slice spiral CT (MSCT) in the post-operative assessment of cochlear implanted electrode.

Methods: Twenty-three cochlear implant recipients were enrolled in this study. All patients were examined with a SOMATOM Sensation 16-slice CT scanner (Siemens) using the following parameters: 120 kV, 100 mAs, 0.

[Diagnostic significance of multi-slice computed tomography imaging in congenital inner ear malformations].

Objective: To evaluate the feasibility and usability of multi-slice computed tomography (MSCT) in congenital inner ear malformations.

Methods: Fourty-four patients with sensorineural hearing loss (SNHL) were examined by a Somatom Sensation 16 (siemens, Germany) CT scanner with following parameters: 120 kV, 100 mAs, 0.75 mm collimation, 1 mm reconstruction increment, a pitch factor of 1 and a field of view of 100 mm.

Using quantitative CT to predict postoperative pulmonary function in patients with lung cancer.

Background: At present, the therapy for patients with lung cancer that achieves a high rate of cure is surgical resection at an early stage of the disease. The aim of this study is to evaluate quantitative computed tomography (QCT) for predicting postoperative pulmonary function in patients with lung cancer.

Methods: The data of thirty-one patients with lung cancer who underwent both pulmonary functional tests and QCT scan before operations were collected.
