Lung cancer is characterized by high malignancy and the majority of patients are diagnosed at the advanced or late stage.Chemoradiotherapy has insufficient effect on this malignant tumor.At present the immune therapy has become a new choice for lung cancer treatment.Ipilimumab,antibody to programmed death-1 ,immune cells,cytokines,melanoma-associated antigen A3 vaccine,liposomal BLP25,belagen-pumatucel-L and polypeptide vaccine have been proved effective for lung cancer through various clinical trials. Futhermore,most of them have been moved forward to phase Ⅲ clinical trials in order to get more strong evidence to support the immunotherapy incorporated into the multidisciplinary treatment of lung cancer.

Background and purpose:Lung cancer is the leading cause of morbidity and cancer-related mortality worldwide. A variety of driver genes were detected in lung cancer. Studies have shown that different gene mutations of lung cancer were found between different races. Most of Uyghurs live in Xinjiang, accompanied by a high morbidity of lung cancer. This study aimed to investigate the expression of driver genes in Uyghur patients with lung cancer in Xinjiang, China.Methods:This study collected the tissue specimens of 43 Uyghur patients with lung cancer, with a very different method to detectEGFR gene expression. real-time fluorescent quantitative polymerase chain reaction(RTFQ-PCR) was used to detectK-ras,ALK,ROS1, mutatedBRAF andPIK3CA gene expression. Analysis of the correlation between lung cancer gene mutations in Uyghur and clinical features of patients with lung cancer were performed.Results:Among 43 cases of specimens,EGFR mutation rate was 11.63%, while theEGFR gene mutation rates in adenocarcinoma and squamous cell carcinoma were 26.67% and 4.76%, respectively.EGFR gene mutation was not detected in large cell carcinoma, adenosquamous carcinoma and small cell lung cancer.EGFR gene mutation rate in patients with adenocarcinoma (26.67%) was signiifcantly higher than that in other types of lung cancer (3.57%). The difference was statistically signiifcant (P=0.024). There were 6 patients withK-ras12/13 heterozygous mutation, and the mutation detection rate was 16.28% (6/43). There were 2 patients withPIK3CA heterozygous mutation, and the mu-tation detection rate was 4.65% (2/43).EGFR andK-ras mutations occurred simultaneously in 1 case. No relationship was found betweenEGFR mutations and age, gender, smoking status, TNM staging, ECOG score among Uyghur lung cancer patients. This study did not ifnd mutation inALK,ROS1 fusion gene andBRAF gene among the 43 specimens. Conclusion:Compared with Asian populations, Xinjiang Uyghur patients with lung cancer have a lower rate ofEGFR mutations and a higher rate ofK-ras mutations, which is similar to the characteristics of European Caucasians.

ObjectiveTo explore the effect of patients with acute cerebral infarction (ACI) at different ages receiving intravenous injection of alteplase for thrombolysis on their prognosis.Methods Ninety-eight ACI patients admitted to Jinghai Hospital of Tianjin from January 2014 to December 2015 were conducted in this study, and they were divided into elderly group (over 75 years old) and younger age group (under 50 years old). The patients in two groups of were given intravenous thrombolytic therapy with alteplase (0.9 mg/kg), 10% of the dose was intravenously injected, and continuously the remaining dose was pumped into the vein for 1 hour. Before the thrombolysis and 1 day and 21 days after thrombolysis, the score of United States National Institutes of Health Stroke Scale (NIHSS) was used to evaluate neurological deficits, the incidence of bleeding adverse event and mortality were recorded.Results Compared to the before thrombolysis, the NIHSS scores after thrombolysis on the 1st day and 21st day were significantly decreased in the two groups (the younger age group 1 day: 6±4 vs. 10±5, 21 days 2±2 vs. 10±5, the elderly group 1 day: 7±5 vs. 10±7, 21 days: 6±4 vs. 10±7, allP < 0.05), and NIHSS score in the younger age group was significantly lower than that in the elderly group on the 21st day after thrombolysis (2±2 vs. 6±4,P < 0.05). After thrombolysis, the incidence of minor mucocutaneous bleeding in elderly group was obviously higher than that in younger age group, the difference being statistically significant [7.69% (4/52) vs. 2.17% (1/46),P < 0.05]; the elderly group had higher symptomatic intracerebral hemorrhage and death events than those in younger age group [1 (1.92%) vs. 0].Conclusion Different ages of patients with ACI can benefit from intravenous thrombolysis with alteplase, showing the younger the age of the patients, the better the benefit they can get and have relatively better prognosis.

Objective To analyze the prevalence and epidemiological characteristics of chronic diseases in Liaoning Province. Methods 16 370 residents from 3 cities and 3 counties in Liaoning province were se1ected by multistage cluster sampling.A household survey with questionnaire was carried out.Chronic diseases were self-reported. Results The total prevalence rate of chronic diseases was 34.48%,and it was higher in the urban(41.85%) than that in the rural(28.65%),higher in women(39.45%)than in men(29.38%).The prevalence rate significantly increased with rising of age above 25 years old.The first five of the most prevalent chronic diseases were those of circulation system(13.18%),movement system(7.84%),digestion system(3.92%),endocrine system(2.19%) and respiration system(2.15%),and they occupied 84.87% of all the cases. Conclusion Cardiovascular diseases,hypertension and cerebrovascular diseases were the first three kinds of the most prevalent chronic diseases,and they would be the main diseases need to control and prevent.Meanwhile chronic gastritis,peptic ulcer and intervertebral disk diseases in the young people should be also concerned

To investigate the role of NADH in preventing apoptotic damage of human hepatic cells induced by chemotherapy drug cisplatin, the ultrastructural changes in hepatic cells were examined with transmission and scanning electron microscopy, propidium iodide (PI) staining was used to measure the apoptotic rate with flow cytometry, the expressions of p53 and bcl 2 gene were detected with RT PCR, the change in caspase 3 and caspase 8 of apoptotic molecules was examined with colorimetric assay. The results showed that, compared with the group of cisplatin, morphological apoptotic changes were not obvious, the apoptosis rate was significantly decreased, p53 mRNA expression was decreased, bcl 2 mRNA expression was increased, caspase 3 and caspase 8 activity levels were kept in a low level in the group of NADH /DDP. The study indicates that NADH can prevent apoptosis of human hepatic cells, and increase the possibility of using NADH to reduce side effects of chemotherapy.

Laminopathies are genetic diseases that encompass a wide spectrum of phenotypes with diverse tissue pathologies and result mainly from mutations in the LMNA gene encoding nuclear lamin A/C. To date, at least 9 different human diseases, which superficially seem to share little with one another, result from LMNA mutations. The position of the mutation within LMNA appears to be associated with the phenotypes. This review gives an overview of genotype-phenotype relationship and describes recent advances in animal models and pathogenic mechanisms.

Objective To study the effect of continuous drainage of subglottic secretion on ventilator associated pneumonia (VAP).Method One hundred and thirty two patients undergoing continuous drainage of subglottic secretion were divided into the control group(n=70)and the experiment group(n=62):the former group underwent sputum suction in case of bucking,wheezy phlegm or decreased oxygen saturation and the latter continuous drainage of subglottic secretion.The incidence of VAP was compared between the two groups.Result The incidences of VAP in the experiment and control groups were 17.7%and 32.9%,respectively, with significant difference between the groups(χ2=3.928,P﹤0.05).Conclusion The continuous drainage of subglottic secretion can effectively reduce the incidence of VAP.

Objective To evaluate the effects of different dosage of aspirin and clopidogrel on the platelet inhibition rate by thromboelastography (TEG)before stent-assisted embolization of aneurysms. Methods The clinical data of 57 patients with unruptured aneurysms treated by stent-assisted coil embolization in General Hospital of Nanjing Military Command were analyzed retrospectively. The patients were divided into a low dose group (aspirin 100 mg + clopidogrel 75 mg,26 cases)and a high dose group (aspirin 300 mg +clopidogrel 75 mg,31 cases). All the patients were treated with aspirin and clopidogrel before surgery. The blood samples were collected on day 3 after oral administration with anti-platelet aggregation drugs. TEG was used to detect the arachidonic acid (AA )-induced inhibition rate of platelet aggregation and adenosine diphosphate (ADP)-induced inhibition rate of platelet aggregation. The platelet inhibition and drug resistance,as well as ischemic complications in the perioperative period between the two groups were compared. Results (1 )The platelet inhibition rates:there was no significant difference in the inhibition rates of platelet aggregation of AA and ADP between low dose group and high dose group at day 3 after oral antiplatelet drugs [AA inhibition rate:(76 ± 21)% vs. (80 ± 21)%;ADP inhibition rate:(72 ± 26)% vs. (73 ± 29 )%;all P >0. 05 ]. (2 )Drug resistance:in the low dose group,the patients of aspirin and clopidogrel resistant were 2 cases(7. 7%)and 1 case(3. 8%),and the patients in high dose group were 3 cases (9. 7%)and 4 cases(12. 9%). No statistical significant difference in the aspirin and clopidogrel resistant was detected in the two groups (all P>0. 05). (3)The ischemic complications in the perioperative period:there was 1 case (3. 8%)with ischemic complications in the low dose group,and 2 cases (6. 5%)in the high dose group. There was no significance difference in the incidence of ischemic complications between the two groups(P >0. 05). Conclusion For patients treated with stent-assisted embolization of aneurysms,no difference could be detected in the inhibitory effect of platelet aggregation between low and high dose groups of aspirin.
