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 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

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

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 summarize and learn the biological properties and clinical features of interdigitating dendritic cell sarcomas (IDCS).Methods The first IDCS patient concurrent with acute myelomonocytic leukemia (AML-M4) described herein,to our knowledge,was studied and 62 IDCS cases reported previously in the literature were reviewed.Results The patient had a history of breast cancer as well as radiotherapy and chemotherapy of it,and the patient showed poor response to 4 cycles of sequential chemocherapy regimens.Based on the laboratory results,IDCS and AML-M4 in this patient were both of myelogenous origination.Furthermore,review of the 62 IDCS patients reported previously showed that as high as 17 ％ of the patients had malignant disease and received radiotherapy or chemotherapy before they got IDCS,and patients of this group had worse prognosis compared with counterpart.Conclusion IDCS has poor prognosis,and therapy-related type worse.Prophylactic measures and stringent screening of the second cancer in those who received chemoterapy or radiotherapy are appropriated and necessary.

Objective To summarize the diagnostic and therapeutic experience of a patient with chronic graft versus host disease (cGVHD) related polymyositis (PM) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods A patient with acute lymphocytic leukemia in com- plete remission received sibling allo-HSCT,and cyclosporine and methotrexate were adopted to pre- vent GVHD.Results Eleven days after HSCT,WBC＞0.5?10~9/L,13 days after HSCT,PLT＞20?10~9/L;27 days after HSCT,chromosome analysis of bone marrow cells showed 99% donor type. Seventeen days after HSCT,Ⅰ~0 acute GVHD of skin occurred,and it was cured by intravenous injec- tion of dexamethasone and methotrexate.Eight months after HSCT,cGVHD of liver happened.Al- though treated by tacrolimus and azathioprine,enzymes of liver were still elevated.At last,tacrolimus combined with sirolimus were used,and enzymes of liver subsided gradually.However,the serum creatine phosphokinase (CK) began to rise from 9 U/L to 3010 U/L,and fatigue all over the patient occurred.Finally,the symptom relapsed,and disability involved with the origin of limbs appeared. The electromyogram and magnetic resonance imaging of concerned muscles confirmed the PM diagno- sis.Although treated with methylprednisolone and plasma exchange,the patient died due to asphyxia, while the CK as high as 21 010 U/L.Conclusion PM is a rare kind of manifestations of cGVHD. When the key muscle tissue was involved,the prognosis is poor.
