Objective To determine pathogens and epidemiological characteristics of adults with acute respiratory infection (ARI) in Beijing area.Methods During 2015,a total of 2 700 cases of ARI were sampled and detected for 9 respiratory pathogens including Legionella pneumophila type1 (LP1),mycoplasma pneumoniae (MP),qrickettsia (COX),chlamydia pneumoniae (CP),adenovirus (ADV),respiratory syncytial virus (RSV),influenza virus type A and B (INFA,IFVB) and parainfluenza viruses type1,2 and 3 (PIVs) using indirect fluorescence immunoassay.Results A total of 620 cases of ARI were tested positive with positive rate of 22.97％ (620/2 700).MP had the highest prevalence followed by LP1,INFB,COX,CP,PIVs,INFA,ADV and RSV in turn.There were 109 cases found mixed infection with the proportion of 17.58％ (109/620).Mixed infection of LP1 along with MP was the most common pattern.The highest detection rate of pathogens was observed in November,whereas the lowest in April in terms of months (x2 =31.288,P＜ 0.01).Different pathogens had distinct prevalent features.The prevalence of male was significant higher than that of female (x2 =6.402,P =0.011).As for stratificated by age,the middle-aged people had the highest infection rate (x2 =9.094,P=0.059).There was no significant difference between the out-and in-patient in terms of infection rate (x2 =0.114,P=0.736).Conclusion MP,LP1 and INFB accounted for ARI of adults in Beijing area during 2015.

Objective To investigate the effects of 4.1N expression in lung cancer A549 cell line on cell proliferation, invasion and migration. Methods A549 cells were cultured in vitro and transfected with lipofectamine 2000 mediation. Three groups were employed: transfection with pEGFP-4.1N plasmid, pEGFP vector plasmid, and blank control, respectively. The mRNA and protein expression differences of 4.1N was examined by semi-quantitative RT-PCR and Western blot in every group after 48 h. The proliferation capability was determined by MTT assay. Invasion capability was evaluated by scratches, adhesion experiments and Transwell chamber model. Results After the transfection, the expression of 4.1N mRNA and protein in pEGFP-4.1N plasmid transfection group was significantly enhanced (P<0.05). The proliferation capability of A549 cells descended extremely (P<0.05). The migration and invasion capability of A549 cells in vitro decreased substantially (P<0.05). Conclusions Transfected with 4.1N gene can significantly increases the expression levels of 4.1N mRNA and protein in A549 cells which are highly metastatic in human. Cell behavior in vitro studies showed that 4.1N gene can inhibit the proliferation, adhesion, invasion and migration of A549 cells, which plays an important role in the metastasis of lung cancer and it may become a molecular marker for metastasis of lung cancer.

Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.

Objective To investigate the correlation between microalbuminuria (MAU) and obesity and its indexes, including BMI, waist circumference(WC), and waist-to-hip ratio(WHR) , among partial community population in Beijing. Methods A total of 2080 subjects who took physical examination in Beijing, including 810 men and 1270 women with a mean age of(50. 9 ± 13. 1 )years, were enrolled. The informed consent has been achieved from each patients. BMI and WHR were calculated based on collected data of height, weight, WC, and hipline. Urine albumin-creatinine ratio(ACR) within the range of 30-300mg/g was classified as MAU. The subjects were divided into normal albuminuria ( NAU ) group and MAU group. The correlations between MAU and different obesity indexes including BMI, WC and WHR, were analyzed. Results Among the 2080 subjects, there was a positive correlation between BMI (r = 0. 1276,P＜0.01) and ACR, and WC (r = 0.0840, P ＜0.01) and ACR. WHR and ACR was irrelevant ( P ＞ 0. 05 ). In univariate analysis, there was significant difference in BMI ≥ 28 kg/m2 ( OR = 2. 02 ) and WC ≥85 cm (male) or≥80 cm (female) (OR = 1.69 ) between NAU group and MAU group (P ＜ 0. 05 ).There was no significant difference in BMI 24-＜ 28 kg/m2, and WHR ≥0. 90 (male) or ≥0. 85 (female)between NAU group and MAU group( P≥0. 05 ). Multivariate logistic regression analysis revealed that BMI ( OR = 1.06) was an isolated independent risk factor of MAU from age ( OR = 1.01 ), female ( OR = 1.42),systolic blood pressure (OR=1.01), TC (OR=1.93) and HDL-C (OR=0.54). Conclusions Obesity is an independent risk factor of MAU among partial community population in Beijing. The correlation between different obesity indexes and MAU also differs.

AIM: To investigate the effects of advanced glycation end products (AGEs) on protein and mRNA expression of macrophage inflammatory protein-1? (MIP-1?) in cultured human umbilical vein endothelial cells(HUVECs). METHODS: HUVECs were cultured with AGEs at different concentrations for 24 h and at a concentration of 400 mg/L for different time.The levels of mRNA and protein expression of MIP-1? in cultured HUVEC were detected by in situ hybridization and Western blot, respectively. RESULTS: In situ hybridization showed that after exposure of HUVECs to AGEs at different concentrations (100 mg/L, 200 mg/L, 400 mg/L) for 24 h, the average integrated optical density values (18.76?3.17, 26.58?1.61, 34.23?2.25) of MIP-1? mRNA expression in HUVECs were higher than that in control group (13.83?1.24, P

Objective: To study relationship among ambulatory pulse pressure (PP), pulse pressure index (PPI) and carotid intima-media thickness (IMT) in aged patients with hypertension. Methods: The 24h ambulatory blood pressures of 159 subjects were measured, and their ambulatory PP [(mean systolic blood pressure (SBP) - mean diastolic blood pressure (DBP)] and ambulatory PPI (ambulatory PP/mean SBP) were calculated. Color Doppler ultrasonography was used to measure carotid IMT. Relationship between ambulatory PPI and carotid IMT was analyzed. Results: Pearson correlation analysis indicated that carotid IMT was correlated with age (r=0.353), mean SBP (r=0.594), mean DBP (r=-0.355), ambulatory PP (r=0.855) and ambulatory PPI (r=0.883), P<0.001 all. Multivariant gradual regressive analysis indicated that carotid IMT possessed significant linear correlation with ambulatory PP and ambulatory PPI (R2=0.789), and standardized regression coefficient β of ambulatory PPI (β=0.621) was higher than that of ambulatory PP (β=0.284). Conclusion: Ambulatory pulse pressure index and ambulatory pulse pressure are good indicators for evaluation of carotid arteriosclerosis, and value of ambulatory pulse pressure index is more than.

The incidence rate of biliary tract cancer is increasing year by year. Systemic therapy is the most important treatment for patients with advanced or unresectable biliary tract cancer. Gemcitabine combined with cisplatin is still the standard first-line chemotherapy, while gemcitabine combined with TS-1 and gemcitabine combined with nab-paclitaxel are also the first-line treatment options. Studies have confirmed that immunotherapy as a back-line treatment has a significant advantage in survival, and the disease control rate of nivolumab is 61% and the median overall survival is more than 1 year. In addition, targeted drugs targeting FGFR2, IDH1/2, HER-2 and other major driving genes of biliary tract cancer also show good antitumor activity, and become research hotspots in the treatment of advanced biliary tract cancer. Summarizing the research progress of systematic chemotherapy, immunotherapy and molecular targeted therapy for advanced biliary tract cancer can provide help for clinical practice.
