Objective To investigate the expression and correlation of NKG2D and sMICA in lung cancer patients. Methods By collecting 30 lung cancer patients as the test group,and taking 30 healthy volunteers as the contrast group, the expression of NKG2D and sMICA in the two groups were examined separately by FACS and ELISA method. Results The expressions of NKG2D in the two groups were (81.56±8.78) %, (85.63±6.62) %. The lung cancer patients were high remarkable. There was a significant difference between the two groups (P <0.05). The expression of sMICA in the two groups were (354.13 ±80.575) pg/ml,(216.53±48.175) pg/ml. The lung cancer patients were low remarkable. There was a significant difference between the two groups (P <0.01). There was a significant relation between the two groups (r =-0.349, P =0.006). Conclusion The expression of NKG2D and sMICA may provid one of the immune targets for diagnosing that can forecast the immune state and malignant metastasis of the lung cancer patients. The significant relation between NKG2D and sMICA may take on main role in the immune escaping of tumor. It may provide the suitable target of the patients for tumor organisms and immune treatment.

Objective To analyze the epidemiological characteristics of imported cases of dengue fever in Guangdong province (GD) and in I-long Kong (HK) during 2004-2006 to provide evidence for further cooperation in the prevention and control programs on dengue fever in the two places.Methods Descriptive statistical analysis was performed on data obtained from dengue fever surveillance and reporting network in GD and from Centre for Health Protection,Department of Health,HK.Results Both from GD and HK 44 and 93 imported cases of Dengue fever were reported during 2004-2006.Most patients from GD acquired their infection from Singapore (13 cases),Indonesia (9 cases) or Cambodia (6 cases) while patients in HK mainly were imported from Indonesia (31 cases),the Philippines (16 cases) and Thailand (15 cases).The peak seasons of the two places were both from July to September.During the non-peak season period,the number of cases in Hong Kong was higher than that in Guangdong.Male/ female ratio was 1.2 : 1 in GD and 1.1 : 1 in HK.Age of patients in GD appeared to range from 6-80 years,with 63.6% (28/44) of them aged 20-39 years.40.9% (18/44) of the cases were engaged in business,services,housework or unemployed.Those cases in HK were between 10-72 years of age,with 63.6%(28/44) of them aged 20-39 years while 47.3%(44/93) of the patients were with the occupation of business,services and industry.More cases in GD had a onset of disease before entering the border (27 : 17) than the cases in HK (35 : 57).The average time interval between onset and diagnosis were 7 and 9 days for GD and HK respectively.Conclusion Frequent travel between Southeast Asia in summer among the working class appeared to be the main factor,causing imported cases of dengue fever in GDand HK.It is crucial to provide health education targeted at these high risk groups in order to prevent importation of dengue fever in the two areas.

Objective: To investigate the current status and changes of disease burden of cardio-cerebrovascular diseases in 1990 and 2016 for Beijing people. Methods: Using the results of the Global Burden of Diseases Study 2016 (GBD 2016) to describe deaths status and disease burden of cardio-cerebrovascular diseases in Beijing. The measurement index included the total deaths, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted years (DALY). Using the average world population from 2000 to 2025 as standard population to calculate the age-standardized mortality rate, DALY rate, YLL rate and YLD rate. Results: The age-standardized mortality rate of cardio-cerebrovascular diseases was 209.24 per 100 000. In 2016, DALY, YLL and YLD of cardio-cerebrovascular was 875.6, 733.6 and 142.0 thousand person-years, respectively, which has increased by 58.05%, 44.24% and 213.47%, respectively, than that in 1990. The age-standardized DALY rate and age-standardized YLL rate of cardio-cerebrovascular diseases in 2016 was 3 552.24 and 2 988.01 per 100 000 which has decreased by 47.90% and 52.43%, respectively, than that in 1990. The age-standardized YLD rate of cardio-cerebrovascular diseases in 2016 was 564.23 per 100 000 which increased by 5.10% than that in 1990. In 2016, the total death of cerebrovascular disease and ischemic heart disease was 17.6 thousand and 23.7 thousand, respectively. DALY was 396.3 and 393.6 thousand person-years in 2016, while 330.2 and 162.7 thousand person-years in 1990, which has increased by 20.02% and 141.92%, respectively. Conclusions: The disease burden of cardio-cerebrovascular disease is serious, especially the burden of cerebrovascular disease and ischemic heart disease. The disability burden of cerebrovascular disease is serious. The disease burden of ischemic heart disease has multiplied.

Objective To study the single nucleotide polymorphisms (SNPs)that predict a patient's risk of grade 2-3 paclitaxel-induced peripheral sensory neuropathy (PSN) in Chinese Han populations.Methods Totally 216 patients received paclitaxel in Peking Union Medical College Hospital from May 2014 to December 2016 were enrolled.DNA was isolated from peripheral blood.Genotyping for eight candidate SNPs was performed on Sequenom-MassARRARYiPLEX platform.Patients were followed up and PSN was assessed by trained physicians according to National Cancer Institute-Common Terminology Criteria for Adverse Events v4.03.Results A total of 209 patients entered the final analysis.Among the candidate SNPs,only rs4141404:A>C(LIMK2) was significantly associated with grade 2/3 PSN (OR:4.32,95%CI:2.37-7.89,P<0.0001).In multivariate logistic regression analysis,both rs4141404:A>C(LIMK2) and history of receiving platinum compound (OR:2.70,95%CI:1.32-5.51,P=0.007) were associated with grade 2/3 PSN.Conclusion rs4141404:A>C(LIMK2) may be the markers of risk of grade 2/3 PSN.
