作者： hong hua XIAOhong liu

AFTER a year of preparation, China is finally ready to host 42 seminars sponsored by 45 Chinese non-governmental organizations during the ’95 NGO Forum to be held at the same time of the UN Fourth World Conference on Women. The wide range of topics concerning women include employment, health, education, politics, legislation, culture, childhood, adulthood and aging, ethnic nationalities, the disabled, human rights, domestic violence, peace, etc. Papers scheduled to be read during the forum are currently being reviewed.

Background CD4^＋CD25^＋ regulatory T cells （Tregs） mediate immune suppression through cell-cell contact with surface molecules, particularly cytotoxic T lymphocyte-associated antigen 4 （CTLA-4）, glucocorticoid-induced tumor necrosis factor receptor family-related protein （GITR）, and transforming growth factor β （TGF-β）, but little is known about the exact role of Tregs in the pathogenesis of asthma. This study sought to characterize the expression of surface markers on peripheral blood mononuclear cells-derived Tregs in patients with atopic asthma and healthy subjects, and to investigate the effect of inhaled corticosteroid on them. Methods The expression of surface molecules on CD4^＋CD25^high Tregs was detected by flow cytometry. The effect of inhaled corticosteroid on expression of the surface molecules on Tregs was determined in vivo and in vitro. Total serum immunoglobulin E （IgE） and high-sensitivity C-reactive protein were measured by enzyme linked immunosorbent assay and latex enhanced immunoturbidimetric assay, respectively. Results Equivalent numbers of peripheral Tregs were found in patients with atopic asthma （stable and acute） and healthy subjects. Tregs preferentially expressed CTLA-4, GITR, toll-like receptor 4 （TLR4）, latency-associated peptide （LAP/FGF-β1）, and forkhead box P3 （FOXP3）. Patients with acute asthma had decreased numbers of CD4^＋CD25^highLAP^＋ T cells compared to healthy subjects and stable asthmatics. Inhaled corticosteroid enhanced the percentage of Tregs expressing LAP in vivo and in vitro dose-dependently. Furthermore, the percentages of Tregs expressing LAP were negatively correlated with total serum IgE levels and severity of asthma, but positively correlated with forced expiratory volume in one second percentage of the predicted value in patients with asthma. Conclusions The results suggest that membrane-bound TGF-β1 is a potential candidate for predicting the severity of asthma, and may contribute to the sustained remission of

With the aim of providing effective periodontal disease therapeutic method, multilayer membranes which were loaded with drug for guided tissue regeneration were prepared using an immerseprecipitation phase inversion technique. Single layer, bi-layer and tri-layer membranes were fabricated with chitosan used as cartier and tinidazole as medicine model which was loaded on the membrane. The influence of layer on structure and properties of membrane were studied by SEM, UV spectrophotometer and mechanical test. Drug release properties of three types of layer membranes were also investigated. The results showed that release rate could be slown down in both bi-layer and tri-layer membranes （to 11 days and 14 days respectively） and tri-layer membrane lasted the longest. After a process of rapid release, the concentration of tinidazole which was released by the membrane was maintained at an efficient dosage level. Compared with single layer and bi- layer membranes, we found tri-layer membrane could play a role in controlling low-rate drug release especially at the early stage of release, and keep an efficient dosage at affected part for a long period of time. The loss of drug which loaded on membrane decreased from 84.6% for single layer to 13.04% for tri-layer. The mechanical strength of three types of membrane were detected and showed that it could meet the requiremens of clinical practice. The membranes especially with tri-layer could be more valuable in application.

A network plan model of ship erection was established based on the network planning technology and the work-package breakdown system. The load-oriented production control method was introduced to build up a throughput diagram model thus it is possible to describe the ship erection process numerically. Based on the digitalized models some cases of production balance of ship erection were studied and three balance indexes were put forward, they are the load balance rate, the input manpower balance rate and the maximum gantry crane operating times. Such an analytic method based on the balance evaluation is the important foundation for digitization and intelligentization of shipyard production management.

Background Thrombosis following plaque rupture is the main cause of acute coronary syndrome, but not all plaque ruptures lead to thrombosis. There are limited in vivo data on the relationship between the morphology of ruptured plaque and thrombosis. Methods We used optical coherence tomography （OCT） to investigate the morphology of plaque rupture and its relation to coronary artery thrombosis in patients with coronary heart disease. Forty-two patients with coronary artery plaque rupture detected by OCT were divided into two groups （with or without thrombus） and the morphological characteristics of ruptured plaque, including fibrous cap thickness and broken cap site, were recorded. Results The fibrous cap of ruptured plaque with thrombus was significantly thinner compared to caps without thrombus （（57.00＋17.00） Bm vs. （96.00＋48.00） Bm; P=0.0076）. Conclusions Plaque rupture associated with thrombosis occurs primarily in plaque covered by a thin fibrous cap. Thick fibrous caps are associated with greater stability of ruptured plaque.

Yield-Increasing-Bacteria (YIB) increased crop yields by two ways: 1) Ecological effect. The YIB produced the effect for rapid reproduction and resistance to extreme environmental conditions and the function of regulating the microflora on plant surfaces(including rhizosphere and phyllosphere).The improved microflora promoted plant growth and inhibited the plant pathogens and deleterioui rhizobzcteria(***) physiological *** produced growth rogulating substances,such as gibberellin and zeatin which increased the growth and yield of crops Based on related research in the past 20 years and current expleration of YIB,the concept of Plant Ecological Engineering was elucidated,*** the microflora artificially in and on plants so as to promote the exprossion of fine characteristies of plants and the prduction potantial, restraning the activity of plant pathogens and DRB,thus making the crop healthy.
