As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

Objective To discuss the impact of repeated contrast media exposure on renal function in patients who received coronary angiography ( CAG) or percutaneous coronary intervention ( PCI) within 1 week after CTA of coronary ateries. Methods A total of 258 patients who received CAG or PCI after coronary CTA were divided into the study group ( n=132, patients had CAG/PCI within 1 week after CTA) and the control group ( n=126, patients had CAG/PCI 1-2 weeks after CTA). Serum creatinine, cystatin C and estimated GFR were tested before and on day 1, 2 and 3 after procedures. The occurance of contrast-induced nephropathy ( CIN ) was recorded. Resu1ts The baseline clinical characteristics of the patients between the two groups had no significant difference. Preoperative and postoperative serum creatinine, cystatin C and eGFR values on day 1, 2 and 3 had no significant difference between the two groups (all P﹥0. 05). There was no significant difference in the incidence of CIN between two groups (5. 3% in the study group vs. 4. 8% in the control group, P﹥0. 05 ) . Conc1usions It is safe and feasible for patients with eGFR≥60 ml/( min?1. 73 m2 ) to undergo CAG or PCI within 1 week after coronary CTA.

Objective To explore the effect of chromosomal abnormality and polygenic inheritance factor in female children with short stature.Methods 1.Chromosome analysis:peripheral blood was drawn for 1 mL and cultured 72 h to analyze chromosome karyotype (Giemsa Banding ) of peripheral lymphocytes.2.Polygenic factor analysis:the children′s final height were estimated based on their parents average height,and analyzed the distribution characteristics of children′s final height and compared the estimate final height with the actual height.Results Eighty-three cases out of the 364 female children with short stature were chromosomal abnormality(22.80%).Among the 83 cases,the 45,XO and 46,X,i(Xq) occupied 70%.The distribution of children target height shifted left,and the target height of 76 cases was lower than 2 standard deviation (-2 s)and the consistency of target height and actual height reached 20.88%.The target height of 7 cases was lower than 2 standard deviation in those whose chromosome turned out to be abnormal,and the consistency of target height and actual height was 8.43%.Conclusions Chromosomal abnormality is one of the most important etiologic agents causing short stature in female children, and polygenic inheritance is another important etiologic agent.

BACKGROUND: Earthquakes, floods, droughts, storms, mudslides, landslides, and forest wild fires are serious threats to human lives and properties. The present study aimed to study the environmental characteristics and pathogenic traits, recapitulate experiences, and augment applications of medical reliefs in tropical regions. METHODS: Analysis was made on work and projects of emergency medical rescue, based on information and data collected from 3 emergency medical rescue missions of China International Search and Rescue Team to overseas earthquakes and tsunamis aftermaths in tropical disaster regions Indonesia-Aceh, Indonesia-Yogyakarta, and Haiti-Port au Prince. RESULTS: Shock, infection and heat stroke were frequently encountered in addition to outbreaks of infectious diseases, skin diseases, and diarrhea during post-disaster emergency medical rescue in tropical regions. CONCLUSIONS: High temperature, high humidity, and proliferation of microorganisms and parasites are the characteristics of tropical climate that impose strict requirements on the preparation of rescue work including selective team members suitable for a particular rescue mission and the provisioning of medical equipment and life support materials. The overseas rescue mission itself needs a scientific, efficient, simple workflow for providing efficient emergency medical assistance. Since shock and infection are major tasks in post-disaster treatment of severely injured victims in tropical regions, the prevention and diagnosis of hyperthermia, insect-borne infectious diseases, tropic skin diseases, infectious diarrhea, and pest harms of disaster victims and rescue team staff should be emphasized during the rescue operations.

Objective To investigate the effects and mechanisms of carbon monoxide-releasing molecule-2 (CORM-2) on LPS induced barrier injure of Caco-2 cells.Methods The model of Caco-2 monolayer cells damage induced by LPS was established by using 50 μg/ml LPS for 24 hours.After preconditioning with different concentrations (10 μmol/L,50 μmol/L,and 100 μ mol/L) of CORM-2 for 1 hour,the cultured well-grown Caco-2 monolayer cells were stimulated with 50 μ g/ml lipopolysaccharides (LPS) for 24 hour.The 100 μmol/L CORM-2 was put into 37℃ and 5％ CO2 incubator for 18 hours until the CO has been fully released,and it became an inactive CORM-2(iCORM-2).The cultured Caco-2 monolayer cells were divided into six groups:the control group,the LPS group,the LC1(10 μmol /L CORM-2 preconditioning) group,the LC2(50 μmol/L CORM-2 preconditioning) group,the LC3(100 μmol/L CORM-2 preconditioning) group,and the LC4 (iCORM-2 preconditioning) group.The apoptosis rates of different groups of Caco-2 monolayer cells were detected using flow cytometry.Cytokines (TNF-α,IL-1β and HMGB-1) levels of different groups were detected using ELISA kits.The levels of tight junction proteins (occludin ZO-1,claudin-1 and claudin-4) of every group were detected using Western blotting with specific antibodies.The structural changes of tight junction proteins were visualized by immunofluorescence technique.Results Compared with control group,cell apoptosis rate and release of inflammatory cytokines such as TNF-α,IL-1β and HMGB-1 in LPS group were significantly higher,and the levels of tight junction proteins were apparently decreased (P＜0.05) in LPS group.Compared with LPS group,cell apoptosis rate and release of inflammatory cytokines such as TNF-α,IL-1β and HMGB-1 decreased,and the levels of tight junction proteins were attenuated obviously,P＜0.05,in CORM-2 preconditioning groups.And the higher the concentration of CORM-2,the more obvious the protective effects.Conclusions This study demonstrates that CORM-2,as one of exogenous CO-releasing molecules,has the capacity to protect the barrier damage of LPS-stimulated Caco-2 monolayer cells in a concentration dependent manner.The higher the concentration of CORM-2 was,the stronger the protective effects were.The protective effects of CORM-2 include reducing Caco-2 monolayer cells apoptosis rate,inhibiting inflammatory cytokines production and release,and restoring distribution and levels of tight junction proteins.

Objective To predict the incidence of birth defects in Xi'an using the auto-regressive integrated moving average product seasonal model.Methods In Xi'an,the trend of the incidence of birth defects was analyzed and tested from October 2009 to August 2015.Using the data from September to December 2015,the actual birth defects were compared with the model fitting data to evaluate the predictive performance of the model.Multiple seasonal ARIMA model was then fitted under time series to predict the incidence of birth defects in 2016.Results Seasonal effect was seen in the incidence of birth defects in Xi'an.A multiple seasonal ARIMA(0,0,1) (0,1,1)12 was established.The mean of absolute error and the relative error were 9.5 and 0.084,respectively,when compared to the simulated number of patients from September to December in 2015,suggesting that ARIMA (0,0,1) (0,1,1)12 has a better predictive ability.Results under the prediction of multiple seasonal ARIMA model showed that the number of patients in 2016 was similar to that of 2015 in Xi'an,with a slight increase and a decrease in the peak value.Conclusion Multiple seasonal ARIMA(0,0,1)(0,1,1)12 model could be used to successfully predict the incidence of birth defects in Xi'an.

Objective To investigate the dynamic epidemiological characteristics of perinatal birth defects in Xi'an so as to provide scientific evidence for the priority of future birth defect prevention.Methods We made a statistical description of the data of perinatal birth defects from 2010 to 2015 reported by all the maternity hospitals in Xi'an.Results The incidence of birth defects in Xi'an from 2010 to 2015 was 89.62/104 (87.60/104,91.74/ 104) and had an annual ascending tendency (x2-157.13,P＜0.01).The top five main birth defects in a descending order were congenital heart disease (26.53/104),polydactyly (13.10/104),total cleft lip (11.42/104),neural tube defects (6.06 /104),and congenital hydrocephalus (5.08/104),accounting for 69.39％ of the total number of birth defects.And the incidence of congenital heart diseases showed a year-by-year ascending trend (x2=837.65,P＜ 0.01).The incidence of birth defects was higher in urban areas than in rural areas (OR 1.108,95％ CI:1.056-1.162).The birth defects were more frequently seen in males than in females (OB=1.151,95％ CI:1.097-1.208).Mother's age ＜20 (OR=1.764,95％ CI..1.532-2.032) and mother'sage≥35 (OR=1.283,95％ CI:1.179-1.395) also were risk factors for birth defects.Up to 72.54％ of the defects were live births.There were 52.83％ cases diagnosed by ultrasound and 46.24％ ones by clinical examination.The prenatal diagnosis rate was 33.20％.Conclusion The incidence of perinatal birth defects in Xi'an from 2010 to 2015 showed an annual ascending trend.We should improve the prenatal diagnosis level of all monitored hospitals in order to reduce incidence of birth defects and increase the quality of population.
