A study the quantitative measurement of DNA content in 3 normal lacrimal glands, 18 pleo-morphie adcnomas and 21 lacrimal gland carcinomas was carried out by flow eytometry. The results showed that pleomorphie adenomas still had the characteristics of DNA content of the normal diploid lacrimal gland cells. The significant increase of DNA index (DI) in pleomorphie adenomas might mean malignant transformation. DNA content of malignant tumor increased evidently and its aneuploid ratio was higher than in pleomorphic adenomas (76.2% VS 16.8%) (P

Objective To study the pharmacodynamics features of cisatracurium besylate in differ-ent age patients. Methods One hundred and eighty patients were randomized to group Ⅰ (50-60 years old),group Ⅱ (61-70 years old)and group Ⅲ (above 70 years old).Each group was subdivided according to the dose of cisatracurium besylate, 0.10 mg/kg (2ED95)or 0.15 mg/kg (3ED95) into group Ⅰ2, Ⅰ3, Ⅱ2, Ⅱ3,Ⅲ2, Ⅲ3(n = 30).ECG, SpO2, PETCO2, HR and neuromuscular blockade were monitored. Intubation conditions were assessed when T1 was zero after cisatracurium besylate administer ration using a 4-part scale.The onset time, TOF no reaction time, duration time, recovery lime and hemodynamic response time were recorded. Re-sults The onset times of group Ⅰ3, Ⅱ3 and Ⅲ3 were significantly shorter than those of group Ⅰ2, Ⅱ2 and Ⅲ2 (P < 0.05).The percentages of patients with excellent intubation condition in group Ⅰ3, Ⅱ3 and Ⅲ3 were 93%, 90%, and 80%, which were markedly higher than those in group Ⅰ2, Ⅱ2 and Ⅲ2 (67%, 60%, 60%). TOF no reaction time and duration time were longer in group Ⅰ3, Ⅱ3 and Ⅲ3 than those in group Ⅰ2, Ⅱ2 and Ⅲ2. There was no significant difference in muscle chalasis among the six groups. Conclusions Cisatracuri-um besylate 0.15 mg/kg produces quicker onset time and acceptable intubation conditions in the different age patients than 0.10 mg/kg. Recovery time is independent on the dosage and age. Aging has no influence on the phannacodynamics of single injection of cisatracurium besylate.

Objective To hy out a course of nursing intervention programmes for patients undergoing coronary intenrentional therapy on the basis of the health belief model(HBM),and estimate its clinical effectbv measuring the change ofquality of life(QOL).Methods 64 patients were randomly selected and divided into 2 groups,the experimental group was treated with the nursing intervetnion on the basis of the HBM,and the control group was treated with routine nursing measures.The quality of life wes compared between the two groups after intervention.Results The total score of QOL,the restricted ability of activity,the therapy satis-faction and the subiective feelings of patients to disease of the two groups had significant difference after inter- vention,P<0.01,but no difference in angina stabilization and occurrence was seen,P>0.05. Conclusions Nursing programmes on the basis of the HBM make the QOL of patients to improve evidently.

Small cell lung cancer ( SCLC ) is one common type of lung cancer in China. No remarkable progress has been made in systemic therapy for SCLC since the 90’ s. However, there are some advances in radiotherapy ( RT) for SCLC, which make it possible to improve treatment outcomes of SCLC. Those advances are mainly made in thoracic RT and prophylactic cranial irradiation for extensive?stage SCLC, radiation dose and technology of thoracic RT for limited?stage SCLC, and significance of prophylactic cranial irradiation for early?stage SCLC. The paper reviews the research advances in the East and West to provide some help and references for readers.

Glaucoma is a progressive optic nerve disease, it can cause structural changes of the optic nerve, resulting in irreversible damage of visual function. Early diagnosis is the key to treat the disease at an early stage to stop or delay the progression of visual functional defects. New technologies, including optic nerve and nerve fiber layer structural tests and visual functional tests, increased the diagnosis rate of primary open angle glaucoma (POAG) at an early stage.
