[Controlled observation of clinical efficacy on cervical spondylosis of neck type treated with scraping and acupuncture].

Objective: To observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

Methods: Eighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group.

[Changes of mean platelet volume, fibrinogen content and blood rheology in peripheral blood of youth patients with cerebral infarction].

This study was aimed to explore the correlation of mean platelet volume (MPV), fibrinogen (FIB) and blood rheology with the youth patients with cerebral infarction, so as to provide the basis for the clinical early diagnosis and treatment. The 109 patients with cerebral infarction aged between 18 - 45 were divided into three group: the large (> 10 cm(3)), middle (4 - 10 cm(3)) and small (< 4 cm(3)) area infarction; 30 healthy persons were served as control group. All the four groups were subjected to 16 examinations, such as MPV, FIB, and rheology (Lηb, Mηb, Hηb, ηp, Lηr, Mηr, Hηr, KVE, EAI, ERI, EDI, EEI, HCT, ESR).

[Determination of gold in copper matte and sintered copper material].

Ore sample, pretreated at 650 degrees C, was decomposed with aqua regia. Gold in the sample solution was then pre-concentrated by adsorbing with polyurethane foam plastic, released with thiourea solution, and determined by inductively coupled plasma-atomic emission spectrometry and flame atomic absorption spectrometry. Based on the characteristic of the copper matte and sinter containing copper, the effects of sample dissolving condition, matrix effect and interference of coexisting elements were investigated.
