ObjectiveTo study the diagnosis of thyroid cancer concurrent with multiple thyroid nodules.Methods The clinical data of 23 patients of multiple thyroid nodules with thyroid cancer undergoing exploration from May 1988 to December 2000 were analyzed retrospectively.ResultsThe diagnosis of concurrent carcinoma was made preoperatively in 6 cases. 13 out of the 23 patients underwent second operation for the postoperative pathology being malignant. Thyroid cancer was identified concurrent with benign nodules in 20 cases. Conclusion Thyroid cancer when found on the background of multiple thyroid nodules is often coexistant with benign thyroid disease, hence the diagnosis is difficult to make clinically. Second operation is sometimes inevitable when the pathology identified a cancer in preoperatively diagnosed benign nodules.

With the establishment and perfection of the system of the socialist market economy, ideological work in hospitals is confronted with quite a few new challenges: ①influence of the complicated circumstances both at home and abroad; ②discord between the managerial mechanisms of ideological and political work and the development of the system of the market economy; ③means and methods of ideological work lagging behind the times. Thus, the authors, in light of their own experience in this aspect, put forward the "three threes" mode, viz. three buildings, three close combinations and three innovations, referring respectively to buildings of ideology, organization and the style of work for the leading group, the contingent of party members and cadres, and the team of cadres engaged in political work; close combinations with the basic requirements of the developmental goals of hospital reform, the difficulties and problems confronted by cadres and the masses in their practical work, and dynamic ideological trends; and innovations in the mechanisms, contents and methods and means of ideological and political work. The authors also point out that attention ought to be paid to the demonstrative, concrete, mass, complicated and advanced nature of ideological work.

Objective To investigate the role of induced sputum in monitoring airway inflammation of chronic obstructive pulmonary disease (COPD). Methods Induced sputum was taken from 26 patients with stable COPD. IL-8 level in the sputum was detected, and the lung function of the patients was determined. 15 healthy volunteers served as control group. Results The total cell count and the number of AM and PMN in sputum were significantly higher in the patients than those in the control group (P

Objective To study the effect of milrinone(Mil) and prostaglandin E1(PGE1) on postoperative right ventricular failure(RVF). Methods 28 patients with congenital heart diseases and pulmonary hypertension undergoing cardiopulmonary bypass (CPB) were randomly divided into four groups: control group (group I), receiving Mil (Group II), receiving PGE1 (Group III), and receiving both Mil and PGE1(group IV). The hemodynamic indexes of all the patients, including mean pulmonary artery pressure (PAP), mean arterial blood pressure (MAP), cardiac index(CI), systemic vascular resistance (SVR) and pulmonary vascular resistance(PVR), were measured and compared. Intubation time and side effects were observed. Results Compared with the other three groups, postoperative PAP、PVR and SVR in group IV deceased and CI increased significantly. The intubation time was also shorter in group IV. Conclusion Postoperative RVF can be treated efficiently by using Mil and PGE1.

Objective:To investigate the effects of IL-2 on the proliferation activity and HCG secretion of first trimester human trophoblastic cells in vitro. Methods:Growing -well 4th generation trophoblastic cells were selected,cultured for 48 h with IL-2 of different concentration. The MTT colorimetric assay was used to analyze the proliferation activity, and radioimmunoassay was used to analyze the secretion of HCG. Results:①Low concentration (100 U/ml,400 U/ml) IL-2 promoted proliferation activity and HCG secretion (P

Ecological charactcristics and biological specific feature of Helleborus thibetanus Fran ch. were briefly described and cultivation technique to transform the wild plant into itscultivated variety was studied to provide a basis for the protection and expliotation ofthe wild resource of H. thibetanus.

After the necessity of research on bio-entities was pointed out, the advances and status quo in research on the relation between bio-entities were analyzed with concrete ideas and project put forward for the research on bio-entities using scientometric methods according to thecitationrelation in bio-entities similar to that in litera-ture.This kind of research will promote and perfect the research on scientometric theory and practice, and open a new visual angle for the research on knowledge management .

Objective:To observe the effect of nape acupuncture on vertebral-artery type cervical spondylosis.Methods:Eighty patients with vertebral-artery type cervical spondylosis were randomly divided into nape acupuncture group and Jiaji acupuncture group,with 40 cases in each group.The patients in the nape acupuncture group were treated with the nape acupuncture plus Jiaji acupuncture,while the patients in the Jiaji group were treated with Jiaji acupuncture only,to observe the functional scale before and after treatment.Results:The total effective rate in the nape acupuncture group was 95.0%,while the total effective rate in the Jiaji acupuncture group was 82.5%.By Ridit analysis,u=5.186,P＜0.01.It indicated that the therapeutic effect in the nape acupuncture group was better than that in the Jiaji acupuncture group.Compared with Jiaji acupuncture group,the difference value of pre- and post-treatment about functional scale of vertebral-artery type cervical spondylosis and the post-treatment score have statistic differences (P＜0.01).It indicated that the therapeutic effect of nape acupuncture group was more obvious in treating vertigo than that in the Jiaji acupuncture group.Conclusion:The treatment of vertebral-artery type cervical spondylosis by Jiaji acupuncture plus the nape acupuncture may enhance the therapeutic effect significantly.

Objective To investigate the level of self-care behaviors and self-efficacy among adult type 2 diabetes patients in community and discuss current problems.Methods A convenient sample of 85 patients with type 2 diabetes in Haiyuncang community was interviewed,using diabetes self-care scale and diabetes self-efficacy scale.Totally 85 questionnaires were got and underwent analysis.Results The index score of self-care behaviors and self-efficacy among adult type 2 diabetes patients in community were 66.98% and 69.02%.There were no significant difference in self-care behaviors of patients whether they attended diabetes lectures or not.Self-efficacy correlated significantly with self-care behaviors.Conclusions The self-care behaviors and self-efficacy of diabetes patients need to be improved,and diabetes education in community should be emphasized and carried out effectively.

Objective To assess quantitatively the association between smoking and the risk of disease and death from pulmonary tuberculosis(TB) by a meta-analysis. Methods Both Chinese and English literatures published from Jan. 1999 to Jun. 2010 about the case-control study of the association between smoking and pulmonary TB were retrieved by searching the electronic resource databases. A meta-analysis was then performed on the comparison and synthesis of findings from included studies. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a software RevMan 4.2. Finally,possible publication bias was tested and a sensitivity analysis was conducted. Results The meta-analysis for total 22 high-quality case-control studies found a pooled OR of 2.56 (95% CI 1. 80 ～3.64) with a random-effects model. Sensitivity analysis showed that pooled OR was 2.56 (95% 1.76 ～3.71 ) by removing two papers of nested case-control study. The OR were 2.13 (95% CI1.76～2.58) and 4.60 (95% CI 1.81～11.69) for disease and death from TB,respectively. After confounding factors,including age and gender,had been controlled the OR was 2.53 (95% CI 1.27 ～5.03 ) whereas 1. 99(95% CI 1.54 ～ 2.56 ) without control of them. Conclusion Smoking can increase the risk of incidence and death of TB. TB control programs and treatment of patients might benefit from interventions aimed at reducing tobacco exposure.
