Difference analysis of Doppler ultrasound blood flow of Cunkou (radial artery) pulse, Renying (carotid artery) pulse, and Fuyang (anterior tibial artery) pulse.

Objective: To analyze the Doppler ultrasound blood flow of Renying (carotid artery) pulse, Cunkou (radial artery) pulse, and Fuyang (anterior tibial artery) pulse in the normal group and the functional constipation with gastrointestinal heat (FCGH) group, and to compare and explore the differences of Renying, Cunkou and Fuyang pulses.

Methods: Sixty normal subjects and 60 patients with gastrointestinal heat constipation were collected in the department of ultrasound, Beijing Anzhen Hospital, Capital Medical University. Doppler ultrasound was used to observe the blood flow indexes including maximum systolic velocity (Vp), maximum diastolic velocity (Vd), mean velocity (Vm), pulse index (PI), resistance index (RI), vascular diameter (D), and circulation blood flow cycle (ET) of Renying pulse, Cunkou pulse and Fuyang pulse in the normal group and patients with gastrointestinal heat constipation.

Variation of ATM protein expression in response to irradiation of lymphocytes in lung cancer patients and controls.

The aim of this research work was to study the cellular response to ionizing radiation (IR) and its relationship with the ATM protein expression levels in lung cancer patients. Heparinized blood samples were collected from 22 controls and 22 lung cancer patients. Each sample was divided into two parts: non-irradiated sample and irradiated sample, which was exposed to 3 Gy X-ray.
