Japanese encephalitis virus (JEV) is a pathogenic mosquito-borne flavivirus which is responsible for outbreaks of severe viral encephalitis. The cellular entry of JEV is a prerequisite for Japanese encephalitis, so the understanding of its underlying mechanisms will provide more approaches for treating such disease. In recent years, increasing research has been conducted to investigate the mechanisms of cellular entry of JEV, and the results of research on other flavivirus have expanded the research directions for JEV. More methods will be used to suppress JEV infection because of the development of E protein antibodies and the discovery of several inhibitors of the cellular entry process. This review will summarize the recent advances in the mechanisms of JEV cellular entry and membrane fusion.

AIM: To investigate the effects of fenofibrate on angiotensin Ⅱ ( AngⅡ)-induced cardiomyocyte hypertrophy .METHODS:Primary neonatal cardiomyocytes were pretreated with fenofibrate (10μmol/L) for 1 h followed by stimulation with AngⅡ(100 nmol/L).The mRNA levels of ANF, BNP andβ-MHC were measured by real-time PCR. Western blotting was employed to determine the nuclear translocations of NFATc 4 and p65-NFκB.Co-immunoprecipitation was used to investigate the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes .In addition, the DNA binding activity of NFATc4 on the BNP promoter was determined by EMSA .RESULTS:Fenofibrate significantly inhibited AngⅡ-induced cardiomyocyte hypertrophy .Fenofibrate treatment inhibited the nuclear translocations of NFATc 4 and p65-NFκB, as well as the interactions of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes induced by AngⅡ.Fenofi-brate inhibited the binding activity of NFATc 4 with the BNP promoter , which was strengthened by AngⅡ.CONCLU-SION:Fenofibrate enhances the interaction of NFATc 4 with PPARα, decreases the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes , and inhibits the DNA binding activity of NFATc 4 induced by AngⅡ, which may be the important mechanisms of fenofibrate on inhibiting cardiac hypertrophy .

0.05). There was only 2/109 cases (5.8%) need a second course of antibiotics because of likely infection and 102/109 cases (93.5%)need not any moor antibiotics. The mean period of antibiotic treatment in group Ⅰ, group Ⅱa and group Ⅱb were (1.2?0.5) days,(4.8?0.8) days and (9.3?1.8) days,respectively.There were significant differences(all P

Objective To establish and test the reliability and validity of the disease related psychological pressure scale of pregnant women with chronic HBV infection,so as to provide mental stress assessment tool for the pregnant women.Methods Item pool was developed after the interview and comprehensively retrieved literatures,then after expert review and rebuilt,the scale items were fixed.Totals of 368 pregnant women with chronic HBV infection disease were investigated and the reliability and validity of scale were test.Results The scale had 5 factors and 24 items,and the correlation coefficient between each factor score and total score was 0.712 - 0.894.The correlation coefficient among each factor was 0.409 - 0.631 which was significantly lower than that between each factor score and total score ( P < 0.01 ).The cumulative contribution rate of 5 factors was 64.055%,and tes-retest reliability of 5 factors was 0.856,0.887,0.828,0.813.The Cronbach' s α of internal consistency of 5 factors was 0.788 - 0.865,and the Cronbach' s α of scale was 0.932.Conclusions The scale has good reliability and validity,and can be used for measuring the disease related pregnancy psychological pressure for chronic HBV infection pregnant women.

Objective To analyze the treatment effects of cervical disc herniation treated by ozone combined with radiofrequency ther-mocoagulation. Methods Ninety cases of cervical intervertebral disc herniation were collected from our hospital in July 2009 to December 2013,who were treated by ozone combined with radiofrequency thermocoagulation. The patients were followed up for at least 3~6 months and the improvement rate was calculated according to the Macnab improved standard. Results All the patients were followed up for at least 3~6 months,according to the Macnab standard improved,50 cases were excellent,good in 25 cases,in 10 cases and poor in 5 cases,the improve-ment rate was 94. 4%. Conclusion The treatment of cervical disc herniation by ozone combined with radiofrequency thermocoagulation is one of the interventional therapy methods,which is minimally invasive and relatively safe. The treatment method has the following advantages, such as,satisfactory effect,accurate operation safety,less complications and without destroying the stability of the spinal structure.

Objective To analyze the manifestation,reason,the processing method of the steel wire implantation with the sereotactic mammography to improve the accuracy of the preoperative positioning.Methods Seventy-nine cases which got the stereotactic steel wire implantation.In 96 lesions, 13 had steel wire displacement.Among them,5 cases got steel wire displacement during the sereotactic process,5 cases got steel wire displacement after the stereotactic process,2 cases got steel wire displacement during the operation,one case did not show the calcification on the postoperative radiography.Results The steel wire displacement occurred in 5 cases during the stereotactic process came from the patients and doctors respectively and the repositioning was needed.The steel wire displacement after the stereoscopic positioning was attributed to the overdose injection of local anesthesia,which led to the mismatch between the depth of Z axis of the mammary gland and the actual depth the computer given,the incorrect method for needle placement,and,neglecting whether the steel wire have got the lesion anchored when pulling out the needle set of steel wire hood,besides,these three kinds of instances above were all exaggerated by the accordion effect.For the displacement within 2 cm,the lesion can be excised toward the pathological change direction according to the position that steel wire prompted and re-place the second steel wire,putting the J-shaped steel wire into the needle hood and taking it out of the body.After repositioning,2 cases had the steel wire prolapse during operation,which resulted from the over-lifting of the steel wire.After placing the steel wire, the radiologist should give an accurate description on the depth and direction to the surgeon and the notch should be taken for incision from the steel wire head end which is proximate to skin.The postoperative specimen from one case had no calcification,which might be related to the condition that the calcification was located in the gland body,which got destruction from the surgical electrical electrotome.The excisionscope should be extended and the short term reexamination is recommended to make sure the complete excision of the calcification.Conclusion It is the gold standard method that implanting the steel wire with the stereotactic mammography to guide the surgical dissecting technique to diagnose non-palpable breast lesion(NPBL).Thorough understanding of the displacement manifestation of implanting steel wire with stereotactic technique and the treatment methods will be helpful in the surgical dissecting guidance.
