HLA (human leukocyte antigen) is critical molecule relevant to immunoresponse, which is always involved in antigen presentation and determining killing activity of immune cells against tumor. The abnormal expression of HLA in lung cancer is believed to be a common phenomena of tumor biology. It has been demonstrated that HLA expression varies in various types of lung cancer, even in differential stages of one type of lung cancer. HLA expression is highly associated with genre, progression and prognosis of lung cancer. The thorough investigations of the relationship between HLA and lung cancer and of mechanism of HLA abnormality will provide useful information for studying of development of lung cancer and tumor immunotherapy.

Objective To explore the changes of plasma somatostatin(SST) in children with septic shock.Methods The level of plasma SST in children with septic shock (test group,n=21) on an empty stomach at shock stage,blood pressure and heart rate recovery stage,recovery stage(at that time clinical symptoms and signs disappeared,infection indicators such as blood routine and CRP returned to normal,about 6-12 days after admission) were detected by competive radioimmunassay,the level of SST in healthy children(healthy control group,n=25) on an empty stomach on morning was detected,too.The levels of plasma SST between septic shock concbined with paralytic ileus group and without paralytic ileus group were compared.Results 1.Level of plasma SST of test group at shock stage[(44.60?16.83) ng/L]was significantly lower than that of control group[(123.15?6.57) ng/L](t=-12.16 P0.05).The level of plasma SST of children with paralytic ileus [(28.10?7.0) ng/L] was significantly lower than that of children without paralytic ileus [(56.98?9.44) ng/L](t=-7.70 P

0.05). Conclusions With intravenous injection of low-dose combination, droperidol and fentanyl can produce effective, painless and safe sedation for TEE examination.

The experiences of surgical treatment of valvular heart diseases in children were reported. Cardiac valve operations were performed in 87 children including 58 males and 29 females between the age of 4 to 14 years ( mean 10 2 years) . Of the 87 patients, 36 underwent mitral valve replacement, 13 aortic valves replacement, 6 mitral and aortic valves replacement, 13 aortic valvuloplasty, and 29 mitral valvuloplasty. Associated cardiac lesions were simultaneously managed. Postoperative complications included low cardiac output syndromes in 7 patients, respiratory failure in 3, and arrhythmia in 5 patients. The operative mortality was 4 60% (4 patients). Follow up was 0 5 to 14 5 years (mean 6 51 years). Late mortality was 3 61% (3 patients). The valvuloplasty operations were first choice for cardiac valve operations in children. It was advisable to use cardiac valve prosthesis of larger size(adult) for valve replacement in children.Anticoagulation with Warfarin was routinely used and the treatment of rheumatic fever should be emphasized postoperatively.

Objective To observe the effect of Sijunzi Decoction (SD) on the mitochondrial DNA deletion of the aging model mice, and to explore its anti-aging biomolecular mechanism. Methods Kunming mice were divided into 6 groups according to the body weight: normal control group, .model control group, high-, middle-and low-dose SD groups (at the dose of 20, 10, 5 g·kg-1 respectively), and vitamin E group (250 mg·kg-1), 20 mice in each group.The mice models of aging were induced by D-galactose. Water maze test was used to evaluate the learning and memory ability of the aging model mice. The effect of SD on the mitochondrial DNA deletion of the aging model mice was ob-served. Results In the hippocampal mtDNA of model control group and low-dose SD group, there were about 3.87 kb fragment missing. But there was no missing pieces in high-and middle-dose SD groups. Conclusion The anti-aging biomolecular mechanism of SD is probably related to the preventive effect on the mutation and deletion of the mitochondrial DNA in the aging model mice.

Objective Investigate the effect of applying clinical pathway on the patients undergoing leiomyoma of uterus. Methods As an experimental group of patients, 50 cases of uterine leiomyoma are treated with clinical pathway. By contrast, another 100 cases are treated with the traditional medical care as control group. Results Waiting time for surgery and hospital stay of the experimental group are less than the control group; and the average hospitalization cost of experimental group is lower than the control group (P< 0.01). Conclusions Application of clinical pathway management will regulate the activities of medical treatment, ensure the quality of health care, improve the feeling of patients, increase efficiency of hospital services, reduce the financial burden of patients, increase the hospital social benefits.

OBJECTIVE:To study the implementation of scoring diseases payment under the control of total budget in some ar-eas of China,and provide reference for the further improvement of the payment. METHODS:Based on the operation process of scoring disease payment in the control of toal budget,the specific practices of Huaian,Nanchang,Zhongshan and Taiwan area, were compared. RESULTS:It showed differences in the control and allocation of total budget,the establishment of scoring diseas-es,the setup of adjustment coefficient,the development of balance methods,the complementary mechanism and the monitor exami-nation setting. CONCLUSIONS:Whether to classify the diseases according to diagnosis and treatment methods,how to setup ad-justment coefficient appropriately,how to reimburse the patients in stages and how to strengthen supervision are worthy of further thinking and exploring.
