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.

To observe the clinical efficacy of diclofenac sodium eye drops for postoperative recurrence of pterygium, and to provide safer drug regimens to prevent the recurrence of pterygium.
● METHODS: From November 2011 to September 2013, 124 patients 134 eyes who underwent surgery because of pterygium in our hospital were randomly divided into trial group ( diclofenac sodium eye drops and sodium hyaluronate eye drops) and control group ( tobramycin dexamethasone eye drops and sodium hyaluronate eye drops), all patients were followed up for 3mo ( once a week ) and the cornea, intraocular pressure and recurrence of pterygium were observed and compared between the two groups.
●RESULTS: Followed up for 3mo, 43 cases (45 eyes) in the trial group and 38 cases (39 eyes) in the control group had done the follow up as planned, in which 14 cases (15 eyes) showed the signs of recurrence, 2 cases (3 eyes) recurred eventually in the trial group, and in the meantime there were 12 cases (13 eyes) with signs of recurrence and 2 cases ( 2 eyes ) with a recurrence eventually in the control group, but no statistical difference was found between the two groups (P>0. 05);there were 6 cases (9 eyes) dropped out of the study with a higher intraocular pressure in the control group, compared to trial group (0 cases of 0 eye), the difference was statistically significant ( P < 0. 05); cornea conditions between the two groups had no statistical significance (P>0. 05).
●CONCLUSlON:Diclofenac sodium eye drops is effective and safe in preventing the recurrence of pterygium.

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: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.

AIM: To investigate the effect of platelet-derived growth factor (PDGF) on ?_3 integrin gene expression and the role of ?_3 integrin on adhesion, migration and proliferation of vascular smooth muscle cells (VSMC) induced by PDGF. METHODS: ?_3 integrin gene expression was detected by RT-PCR. After ?_3 integrin extracellular domain was blocked, VSMC adhesion, migration and proliferation were measured by adhesion assay, a wound-culture model and [~3H]-TdR incorporation, respectively. RESULTS: After the interaction between ?_3 integrin and extracellular matrix was blocked, VSMC proliferation was inhibited in some degree and the rate of [~3H]-TdR incorporation into VSMC decreased 39%. The cell adhesion and migration were significantly inhibited when 10 mg/L anti-?_3 integrin antibody was added (P

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.
