Low intensity millimeter(6mm,50GHz,100mW) wave was used to irradiate to 15 blood samples. The radiation time respectively were 15min、30min and 60min.Series rheological and biophysical parameters about the erythrocyte were systemically tested. There included viscosity of blood 、deformability and congregating ability of erythrocyte、hemolysical fragility 、anion transport in erythrocyte membranes and configuration of erythrocyte etc. From the point of biophysics, the biological effects of low intensity MMW to cells were investigated.

1. The central retinular cells R_7 in the compound eye of male housefly can be divided into two types which are called here R_(7a) and R_(7b) respectively. R_(7a) approximate many features of R_(1-6) cells, which have a larger, cell body, rhabdomere and axon, terminate in the first optic neuropil (lamina). R_(7b) approximate many features of R_8 cell and project directly to the second optic neuropil (medulla). 2. The central retinular cell R_(7a) in the compound eye of male housefly distribute mainly the dorsal region of the eye, there are a few of R_(7a) in the ventral region of the eye, which only distribute in the first and second row ommatidia under equatorial line, but not found in the compound eye of female housefly.

Objective To investigate the status of diabetes and its risk factors in Karamay.Methods A sampling survey was carried out in Baijiantan district of Karamay from March,2003 to Dec.,2003,all subjects aged 20 to 75 and lived 5 years and above were selected with stratified sampling method according to the age structure of the inhabitants in Karamay.Results Diabetes prevalence was positively correlated with age(OR=1.047),male(OR=1.922),obesity(OR=1.641),hypertension(OR=1.624) and hyperlipidemia(OR=2.131)(P

Objective To evaluate the use of keyhole dynamic magnetic resonance (MR) imaging in evaluation of pituitary microadenomas. Methods Fifty three patients with pituitary microadenomas proved by operation or clinical findings such as headache, amenorrhea, lactating, fat or acromegaly were retrospectively studied on dynamic MR, conventional contrast enhanced MR, and unenhanced MR. Then the image data were analyzed by two experienced doctors who didn′t know the details and three degrees were made as follows: grade 0, no evidence of the tumor; gradeⅠ, asymmetry signals in the pituitary; and gradeⅡ, nodulated or sheets signals in the pituitary. The grading data were compared with statistical methods. Results In dynamic MR grading system: grade 0 was revealed in 1 patient, gradeⅠ in 29 patients and gradeⅡ in 23 patients. In conventional enhanced MR: grade 0 in 26 patients, grade Ⅰ in 17 patients and gradeⅡin 10 patients. In conventional unenhanced MR: grade 0 in 39 patients, grade Ⅰin 10 patients and grade Ⅱ in 4 patients. The diagnostic rate of dynamic MR, conventional enhanced MR, and unenhanced MR was 98.1%, 51.9%, and 26.4%, respectively. ( P

目的：对完全性失语的患者经言语治疗后的结果进行分析。研究方法：对10 例完全性失语患者进行筛查，采用中国康复研究中心失语症检查及头颅CT、MRI确诊为完全性失语，并对患者进行语言治疗。结果：10 例患者中5 例有改善，并且在发病后7－12个月比发病后的前6 个月恢复得快。结论：完全性失语的患者经言语治疗后可在一定范围内得到恢复，但要达到日常生活交流必须借助辅助交流。本文同时就完全性失语的定义、言语特征及预后进行讨论。

Micro-and ultrastructure of the photoreceptors and first visual ganglion in the different regions of the compound eye of the wild male and female housefly, and the projections of the photoreceptor cells within the subsequent visual centers have been studied. The morphology of the retina and lamina ganglia in the front dorsal and the equatorial regions of the male compound eye and the front ventral region of the female one, and the projections of the retina within the lamina show the sexspecific characteristics underlying the function of chasing behavior in the housefly.

The changes of the ultrastructure of the photoreceptors in the compound eye of horsefly (Tabanus mandarinus) were observed electromicroscopically at both the mid-day and mid-night. We found that there were various structural changes in cones, pigment cells, retinula cells, rhabdomeres at the two different times.The functional significance of the day and night changes of the photoreceptors and their relations to natural light illumination were discussed.

Objective To evaluate the effect and safety of anticoagulant citrate dextrose solution A (ACD-A ) in continuous blood purification (CBP) for patients at high risk of bleeding with ARF. Methods Twelve patients at high risk of bleeding, treated with continuous venovenous hemofiltration(CVVH), were divided into regional citrate anticoagulant (RCA) group and control group. In the former, ACD-A solution was delivered, pre-filter , with the rate adjusted to maintain a postfilter ionized calcium (iCa2+) level between 0.30-0.40 mmol/L. Before the extracorporeal blood returned to the patient, 10% calcium gluconate was infused to maintain a systemic iCa2+ level between 0.90-1.20 mmol/L. In control group, CVVH were performed either with low dose of heparin LMW sodium (1700-2500 IU/12 h-24 h)or without anticoagulant. The life span of each hemofilter was recorded. In RCA group, prothrombin time (PT), activated partial thromboplastin time (APTT) , acid-base changes, serum sodium and iCa2+ were monitored pre- and during CVVH. Result In the whole duration 1192.5 hours of CVVH in RCA group and 596 hours in control group, 62 and 42 hemofilters were used, respectively. Filter survival was 65.3% at 24 h and 24.5% at 48 h in RCA group,while 14.5% and 0 in control group. The mean life span of filter in RCA group was significantly longer than that in control group[(29.4?21.0) (1.5-71.5)h vs( 14.2?8.2) (4.5-40)h, P

Objective: To explore the value of CYP2C19 genotype polymorphisms for guiding the strategy of anti-platelet therapy in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) with clinical prognosis.
Methods: A total of 326 CAD patients with PCI treatment received CYP2C19 genotype examination. According to CYP2C19 polymorphisms, the patients were divided into 3 groups. The patients with CYP2C19*1/*1, fast metabolism were defined as Routine group, who received clopidogrel 75 mg/day,n=128. The patients with CYP2C19*1/*2, CYP2C19*1/*3, CYP2C19*2/*3, CYP2C19*2/*2, CYP2C19*3/*3, medium and slow metabolism were further divided into 2 groups as High clopidogrel group, who received clopidogrel 150 mg/day,n=99 and Ticagrelor group, who received ticagrelor 90 mg/bid,n=99. The changes of platelet aggregation rate (PAgT) at before and 1, 3, 6 months after PCI were observed, the major adverse cardiac events (MACE) and bleeding condition were compared among different groups at 6 months after PCI.
Results: The PAgT was similar between High clopidogrel group and Routine group at 1, 3, 6 months after PCI, P>0.05;while compared with High clopidogrel group and Routine group, the PAgT decreased in Ticagrelor group at 1, 3, 6 months after PCI,P<0.05. The occurrence of MACE was similar between High clopidogrel group and Routine group at 6 months after PCI,P>0.05; while compared with High clopidogrel group and Routine group, Ticagrelor group had much less MACE occurrence,P<0.05. Ticagrelor group had no more major bleeding events than the other 2 groups,P>0.05.
Conclusion: High dose clopidogrel does not increase MACE occurrence in CAD patients with CYP2C19 medium and slow metabolism after PCI. Ticagrelor may decrease PAgT and MACE occurrence without elevating the major bleeding events.
