The results of the determination of SACE activity in recent four years were reported. It was found that the levels were 33.5?5.1, 41.6?8.6, 33.4?8.6, 37.2?4.5, 53.6?7.3 and 31.4?13.0 in the healthy persons (37 cases), silicosis (40 cases), lung cancer (30 cases), pulmonary tuberculosis (18 cases), active sarcoidosis (4 cases) and inactive sarcoidosis (3 cases), respectively. The clinical value of the SACE measurement in sarcoidosis was discussed. The results showed that the SACE measurement is helpful to the diagnosis and monitoring of sarcoidosis, because the SACE activity was significantly elevated in most cases of active sarcoidosis, decreased during the stage of remission and elevated again during exacerbation. However, sarcoidosis can not be ruled out even though a normal SACE activity is measured. In addition, the SACE activity can also be elevated in the other pulmonary or systemic diseases, but the differentiation of these diseases from sarcoidosis is not difficult clinically. The SACE measurement can not be taken as a predictor of the prognosis of sarcoidosis.

To effectively implement "Technical manual of clinical blood transfusion ",ensure the safety of clinical blood transfusion,and decrease nursing human resources cost,a nursing station for blood delivery hospital was established. This paper introduces the environment and facility,basic setup of information-based management,organizational structure,operation and management mode of nursing station for blood delivery. With flexible work mode,standard distribution process,safe and timely distribution,and effective quality control of blood transfusion process,the nursing station for blood delivery ensured the safety and effectiveness of clinical blood utilization,strictly implemented "Technical manual of clinical blood transfusion ",made full use of human resources,relieved the stress of laboratory technicians of blood transfusion department,and improved the satisfaction rate of medical staff towards blood transfusion department.

0.05), respectively, the antidiarrheal rates of which on the first 3 days were 94% and 71%(P

Objective To investigate the fluorescence quantitative PCR (FQ-PCR) based on TaqMan-MGB( Minor Groove Binder) technique for quantification of fetal DNA in maternal plasma and its variation during pregnancy. Methods Maternal DNA extracted from 237 plasma samples obtained from 30 pregnant women (5-40 gestational weeks and post delivery). The TaqMan-MGB probe and SRY primers were designed to amplify the SRY gene sequence of Y chromosome in maternal plasma by FQ-PCR. Results This system was sensitive enough to detect a male DNA among 20 000 female DNA. Fetal DNA can be detected in maternal plasma as early as 6+6 weeks of gestation and increased with the pregnant progress with the peak level at the third trimester. Between 24- 48 h after delivery, the SRY gene was negative in maternal plasma. The percentage of fetal DNA concentration in maternal total plasma DNA was 4. 88% in the first trimester, 6. 10% in the second and 4. 77% in the third trimester. The SRY positive signal was obtained from samples of 13 women bearing male fetuses and no signal was detected for all of the 17 women bearing female fetuses. Conclusions The FQ-PCR for quantification of fetal DNA in maternal plasma is highly sensitive, specific and reliable. Fetal DNA does present in maternal plasma at a higher concentraton. FQ-PCR may be useful in nonin-vasive prenatal diagnosis.

Cyanoacrylate adhesive (CA) is a common clinical medical adhesive. In recent years, CA has been used as a securement device for vascular access devices. This paper reviews the development and properties of CA, the effect of CA on catheter failure rate, skin damages, the number and interval time of dressing change, the satisfaction of nurses and patients as well as economic benefits, which provides references for the clinical practice and scientific research.

With the public hospitals expanding,the nurses at age of marriage or bearing are enrolled and account for large part of all health care workers in China.A significant percentage of nurses in the period of pregnancy or lactation,especially abortion and sterility,deteriorate the shortage of nursing human resources and the nurses' health.It is essential to cope with the matter in order to maintain the nurses and contribute to the professional development.In this paper,we review the human resource management of the nurses during the periods at home and abroad from the human resources,occupational protection and management approaches,which is contributed to supplement the human resource.

Objective To improve recognition of the processus articularis arthropathy.Methods CT findings of the processus articularis arthropathy was analysed.Results According to the CT findings of the 94 cases processus articularis arthropathy,CT signs and the syndrome of this disease were summarized five types:①zygapophyseal hypertrophy and osteophyte formation;②stricture or asymmetry of articular space ;③vacuum phenomenon of articular space ;④pachynsis or calcification of articular capsule ;⑤articular instability.Conclusion The processus articularis arthropathy is a very high incidence of a disease.The CT scanning is very important significance to the disease.

Objective To evaluate the significance of selective salpingography(SSG)and fallopian tube recanalization(FTR)in diagnosis and treatment for obstructive infertility.Methods Totally, 268women with infertility caused by obstruction of the fallopian tube were divided randomly into two groups, one (Group A)with a non-operative hysterosalpingeal system by insertion of co-axial cannula and guiding filament made by COOK Corporation in the US and another(Group B)with a self-prepared hysterosalpingeal system modified based on the apparatus of COOK Corporation, for SSG and FTR.Then, efficacy of SSG and FTR for the infertile women was evaluated by one-year cumulative pregnancy rate and reeanalization rate of the fallopian tube.Resnits One hundred and seventy of 198 fallopian tubes were recanalized in Group A, with a recanalization rate of 85.8%, and 290 of 320 tubes in Group B were recanalized.with a recanalization rate of 90.6%.reaching statistically significant difference.Furthermore, recanalization rate varied with different sites of occlusion of the fallopian tube.Pregnancy rate was 35.3%(36/102)in Group A, significantly higher than that in Group B(47.6%, 79/166).As the same, pregnancy rate varied with different sites of occlusion of the fallopian tube.Conclusion Selective salpingography and fallopian tube recanalization with self-prepared hysterosalpingeal system have dual effects on diagnosis and treatment for tubal infertility of women, which are simpler, safer and more reliable, worth to be clinically applied.

Objective To discuss the diagnostic value of the lumbar intervertebral disc degeneration by CT scanning.Methods The clinical representation and CT view of 809 cases with degenerative lumbar intervertebral disc were retrospectively analyzed.Results According to the different CT representation character,the degenerative lumbar intervertebral disc may be divided into the lumbar intervertebral disc denaturation bulge in 96 cases and the lumbar intervertebral disc herniation in 713 cases.Conclusion CT scanning is a value method to diagnosing degenerative lumbar intervertebral disc.
