Respiratory viral infections are the most common cause of infantile wheezing, as well as one of the major inducents of acute exacebarbations of chronic childhood asthma. Recent studies focus on the mechanism of virus-induced airway inflammatory response which is still not completely clear. Many new pathophysiologic mechanisms such as epigenetics are advanced to explain the association between viral respiratory infections and asthma attack. In the present reports, recent data on the role of early-life viral infections in the development and progression of childhood asthma are reviewed.

Chronic kidney disease(CKD)is increasingly recognized as a global public health problem.Uncontrolled complications of CKD,especially cardiovascular diseases,contribute greatly to the premature death and unfavorable prognosis.Recent evidence shows that CKD complications may occur earlier than previously thought.CKD complications deserve early detection and active treatment.Periodical follow-up and regular check should be done to adjust the therapeutic condition.Clinical practice guideline or recommendation based on evidence-based medicine is essential for management of CKD complications.Personalized treatment should be considered to improve survival and quality of life,and to make patient return to society.

OBJECTIVE:To provide reference for rational application of TCM injection. METHODS:The utilization of TCM injection in our hospital during 2011-2014 was analyzed in terms of species,consumption sum,DDDs and DDC,etc. RESULTS:The type and consumption sum of TCM injection kept stable in our hospital during 2011-2014. TCM injection for activating blood circulation to dissipate blood stasis as Shuxuetong(Heilougjiang),Danhong,Shuxuening took up the front of consumption sum in 4 years. Top 3 TCM injections in the list of DDDs were Shuxuetong,Shuxuening(Heilougjiang), Danhong/Xueshuangtong corre-sponded to consumption sum. DDC of TCM injection were kept around 100 yuan. DUI ratio of TCM injection were almost equal to 1 or close to 1. CONCLUSIONS:The amount and DDDs of TCM injection are synchronous in our hospital,and the utilization of TCM injection is stable and rational basically in our hospital. TCM injection with suitable price and definite efficacy take up a large share,and the amount of TCM injection for clearing away heat and toxic material with anti-inflammatory effect increase rapidly.

Objective To study the mechanism of toxicity of methylmercury on primary cultured SD rat astrocyte.Methods Treat primary cultured SD rat astrocyte with methylmercury.Determine the level of cyto-oxidation redoxin with High Performance Liquid Chromatography(HPLC).Western-blot was applied to examine the protein expression of nuclear factor erythroid 2 related factor 2(Nrf2).Results With the increase of the concentration of methylmercury,the redoxin level of astrocyte was apparently decreasing.When the concentration of methylmercury was at a low level,the expression of Nrf2 was increasing with the increase of the methylmercury concentration.When the concentration of methylmercury was at a high level,the expression of Nrf2 was decreasing with the increase of the methylmercury concentration.Conclusion The toxicity of methylmercury on primary cultured SD rat astrocyte can be realized through altering the function of GSH and Nrf2.

Population pharmacokinetics(PPK),which is based on the principle of statistics,can be used to estimate various inter- and intra-individual factors which affect pharmacokinetics.By using Bayesian estimator,PPK can predict individual pharmacokinetic parameters accurately.PPK is widely used in the immunosuppressive therapy with cyclosporine,tacrolimus,mycophenolic acid and sirolimus.

Objective To summarize the clinical effects of retrograde intramedullary nail in treating distal femora| fracture. Methods Retrospectively analysed 52 cases of intereondyiar and supracondylar fracture of femur treated with retrograde intrameduUary nail. Results All cases were followed up for 6 to 24 months. All fracture were union except 2 reoperations cases had delay union. Conclusion Retrograde intrameduUary nail has supreme biological stability and allowed early exercise. It also can shorten operation time, reduce damage of periosteum and reduce delay union rate.

Objective To observe the influence of self-management on health care behavior through health education for patients with hypertension after a self-management model was brought to the communities. Methods There are 252 cases chosen randomly from 546 hypertensive patients in 19 communities to participate in the standard management of hypertension in communities voluntarily. They improve their self-management skills through attending lectures, the guidance of healthy lifestyle and self-management manuals. A scientific self-management methods was established and the support of the society and family was improved. The self-control method was used to analyze this study. Results There are significantly differents (P<0.05 ) in basic health knowledge understanding, self-management skills, and blood pressure control after health education compared with before. Conclusions Patients with health education can improve the self-management level. There are obvious effects on changing the bad lifestyle,improving blood pressure control rate, and decreasing the complication of patients with hypertension.

Gastric cancer(GC) is deeply threatening the health of our people, the mortality rate of GC is the second death cause of carcinoma i n our country. Since the lack of special clinical symptom at the early state of GC, detecting GC at the molecular biological level is expected to diagnose early gastric cancer. This article discusses some markers such as PCNA, p53, telomera se, ras protein and so on to assess the possibility of diagnosing the early gas tric cancer with these molecular biological markers. According to analyzing rela ted papers published, PCNA and p53 were found to be the molecular biological mar kers which should be firstly taken into account in diagnosing gastric cancer. Bo th of them can be easily detected by using immunohistochemical method. Telomeras e is also a good marker, but because of its difficult technology and high cost, it is not so practicable as the former two as the diagnostic marker of early gas tric cancer. Besides, ras potein can also be taken into account as the early det ecting auxiliary marker for GC.

With continued ozone deletion and increased ultraviolet application,ultraviolet (UV) induced eye injury receives more attention,especially for astronauts,residents on high elevation plateaus and other people exposed to intense beams of UV.Continuous exposure to UV can lead to damage of conjunctiva,cornea,crystalline lens and retina,which are correlated with conjunctivitis,keratitis,ocular tumor,climatic droplet keratopathy,and pterygium.This paper focuses on the effect of UV on eyes,with a systematic elaboration of UV-induced eye injury.
