The acticle describes a time—resolved fluoroimmunoassay for serum progesterone,based ona competitive solid—phase antigen technique。Progesterone—BSA conjugates are coated onto thewhite opaque microtitration wells。Anti—progesterone antibody is biotinylated.Eu~(3+) are labelledto streptavidin as the tracer.The assay standard curve covers a range of 0.1—100ng/ml.Thelowest detecting limit is 0.05ng/ml。The intra and inter C?V s are 6.45% and 8.93% respec-tively.The average recovery is 89.5%.40woman samples are measured with RIA and presentTRFIA and the results are satisfactory,giving a correlation coefficient of 0.9619.The perfor-mance charicter—istics of the assay are discussed and compared with other known immunoas-says.

Objective To explore the effective communication between therapists and inpatients during rehabilitation treatment. Methods The communication needs were evaluated among 150 inpatients, including stroke and spinal cord injury, following physical dysfunction in 7 aspects to determine the patient's psychological and demand conditions. Then, targeted and effective communication plans were developed and adjusted according to the individual changes of the patients at all stages of the pathogenesis and the patients' feedback information. Finally, the patients' satisfaction surveys were issued when the patients discharged. Results After effective communication was used, 98.5% patients felt satisfied with shortened hospital stay and satisfactory limb function. Compared with the previous patients, effective communication can significantly improve the outcomes and reduce the incidence of doctor-patient disputes. Conclusion Effective communication is helpful for the patients to understand the disease, which can enhance the rehabilitation of compliance and improve rehabilitation outcome.

目的探讨以主动运动为主的社区康复训练对脑卒中恢复后期患者日常生活活动能力的影响。方法将85例社区脑卒中恢复后期患者分为对照组42例和康复组43例。出院后，康复组继续在社区接受以主动运动为主的康复训练，对照组不再进行任何康复训练。结果经过90 d左右，康复组Barthel指数明显提高（P<0.01）。结论以主动运动为主的社区康复训练可提高偏瘫患者的日常生活活动能力。

In Japan, acupuncture and massage does not belong to medical treatment, but a behavior similar to it.Acupuncture and massage along with Chinese medical science suffered tremendous impact since Japan's Meij Restoration.This paper made a summary on the history, development, academy, and current educational situation of Japanese acupuncture and massage industry.

Microwave ablation(MA)has been one of the most quickly developed minimally invasive techniques for trearing hepatocellular carcinoma(HCC)in the last decade.Under accurate imaging guidance,MA shares the common advantages of thermal ablation such as flexible treatment approaches,good tolerability and the ability to consistently create reproducible and predictable necrotic areas.It also exhibits several particular advantages compared with other thermal ablation methods,including higher thermal efficiency,higher capability of coagulating blood vessels,faster ablation time,and an improved convention profile.Over the years,MA equipments,especially the antenna,have been refined for safety and to increase the coagulation zone.With the development of internally-cooled antenna and using the frequency of 915 MHz nficrowave,the technique is becoming safer and the coagulation zone increased significantly.Initially,MA was limited to the treatment of small HCC,but with the improvement of antenna and treatment strategV,large HCC(＞5 cm)can also be ablated effectively.For the"curative"treatment of HCC.the following eriteria need to be met:single HCC with the lesion of 6 am or smaller;three or fewer HCC lesions with a maximum diameter of 4 cm,and absence of portal vein thrombosis or extrahepatic metastases.A five-year cumulative survival rate has exceeded 50%,which is comparable with resection.Moreover,the local immune function is enhanced after MA.A change in immunocyte infiltration takes place in number,configuration and location after patients with HCC are treated with MA.Further research for MA may be focused on the improvement of the maneuverability of the equipment,increase of the accuracy of antenna puncture and consummate the clinical therapeutic standardization.

Tumor metastasis, the main characteristic and important indication of malignant tumor, is also the primary cause of death for most cancer patients. The tumor metastasis is a multistep process involving various factors, multiple interactions of many genes as well as the microenvironment. To investigate the mechanism of tumor metastasis will help us understand the essences of metastasis process, therefore exploring molecular targets for clinical diagnosis and treatment of cancer.

Antisense oligonucleotides is appplicated abroadly in cardiovascular disease.It aims at the target genes involved in molecule mechanisms of disease pathogenesis.This technology reveals good foreground as a kind of clinical drug because of its researchful and therapeutic function in hypertension、coronary disease,complications of heart transplantation and failure.

Background and purpose:Small cell lung cancer(SCLC) is a highly aggressive malignancy with a 5-year survival rate of less than 10%.These features suggest the enrichment in cancer stem cells.Our study was aimed to establish a small cell lung cancer cell line from primary cultured from lung cancer tissue,and to identify and isolate cancer stem cells from the early generations of the established cell line.Methods:By using a serum-free medium,lung cancer primary cells were cultured from a small fresh lung cancer cell sample,and a small cell lung cancer cell line was established after passaging the cultured cells.Lung cancer stem cell markers were searched by using flow cytometry analysis to sort through the third or forth generation cells of the established cell line.Biological characteristics of lung cancer stem cells were studied by using the single cell clone formation test,plat colony formation test and cell sphere formation test.Results:A small cell lung cancer cell line was established by primarily culturing a fresh lung cancer sample.The cell line could easily passaged more than 25 generations.When the third or fourth generation cells of the established cell line were checked by flow cytometry,there was a small population of cells that were obviously with CD44 stronger positive(CD44++ cells,5.1%) than the main population cells,which were CD44 weak positive(CD44+ cells).CD44++ cells showed stronger colony formation ability than the CD44+ cells.Furthermore,only the CD44++ cells could form stem cells when a single cell was seeded in a well of 96 well plates.Most importantly,only the CD44++ cells could form cell spheres in ultra low attachment 96 well plates.These results indicated that the CD44++ cells enriched more cancer stem cells in the small cell lung cancer cell line.When CD44 and CD90 antibodies were co-stained,the cells of the established cell line could be separated into 4 populations,i.e.CD44+CD90-,CD44+ CD90+,CD44++ CD90+ and CD44++ CD90-cells.CD44+ CD90+ cells were the smallest population cells in the cell line,with a ratio of about 1.9%.When cultured in ultra low attachment 96 well plates,CD44++ CD90+ cells had the strongest cell sphere formation ability when compared with other population cells,indicating that CD90 might also be a small cell lung cancer stem cell marker.Conclusion:There were cancer stem-like cells in primary cultured small cell lung cancer cell lines,CD44 and CD90,which might mean that they could be lung cancer stem cell markers.
