Enterovirus 71 (EV71) is a major causative agent of hand, foot and mouth disease (HFMD). belongs to family Picornaviridae, genus Enterovirus, species A. EV71 infection usually affects subjects aged <5 years. HFMD caused by EV71 infection is usually mild in children. However, in some cases EV71 infection can lead to severe neurogenic disease and even death. EV71 infection has caused epidemic worldwide (especially in the Asia Pacific). HFMD caused by EV71 has become a major public-health prol lem across the Asia Pacific. In EV71 infection, the pathogenesis is determined by viral and host factor, Here, we review research on host susceptibility and how EV71 suppresses immune and intracellular ri

Objective To explore the dosimetric difference between different radiotherapy technologies in the treatment of early peripheral stage non?small ?cell lung cancer ( NSCLC ) . Methods Four?dimensional computed tomography scans and delineation of target volumes and organs at risk ( OARs) were performed in 5 patients pathologically diagnosed with stage T1/T2 peripheral NSCLC who were admitted from 2014 to 2015. Target volumes contained gross tumor volume (GTV), internal target volume (ITV), and planning target volume (PTV). ITV was contoured on the maximum intensity projection images. PTV was defined as ITV plus a 5 mm margin. OARs contained the heart, lung, esophagus, and spinal cord. The Monaco 5. 0 treatment planning system was used to design three plans. The three?dimensional conformal radiotherapy (3DCRT) plan had 11 fields in the diseased lung covering the PTV plus a 0. 2 cm margin. The sliding window intensity?modulated radiotherapy ( SW?IMRT ) plan had 9 fields in the same areas as the 3DCRT plan. The volumetric modulated arc therapy ( VMAT) plan had the gantry rotating 180° around the diseased lung. The evaluation criteria referred to the RTOG 0618 trial. Comparison was made by paired t test. Results The SW?IMRT plan had a significantly better homogeneity index than the 3DCRT plan ( 1. 03 vs. 1. 24,P= 0. 017 ) . Compared with the VMAT plan, the mean monitor units in the 3DCRT plan was significantly reduced by 24. 5%( P=0. 022) . The V30 and V40 of the 3DCRT plan were significantly reduced by 29. 4% and 28. 4%, respectively, compared with the SW?IMRT plan ( P=0. 003,0. 006) and 56. 7%and 59. 7%, respectively, compared with the VMAT plan ( P=0. 041,0. 019) . Conclusions 3DCRT may be an appropriate radiotherapy method for early stage NSCLC.

Objective To detect de novo development of anti-HLA antibodies after renal transplantation, and to investigate their influence on graft function. Methods 384 kidney recipients,who were negative for anti-HLA antibody before transplantation, were monitored for anti-HLA antibodies over a period of 3-96 months, and a sensitive enzyme-linked immunosorbent assay (ELISA) was used to detect anti-HLA antibodies. HLA antibody >10 % was defined as positive levels. Results Among 384 recipients tested, 318 recipients (82. 8 %) were negative for anti-HLA antibody after transplantation; 66 recipients (17. 2 %) developed de novo HLA antibodies, 3 recipients with HLA class Ⅰ, 61 with HLA class Ⅱ, 2 with both HLA class Ⅰ and Ⅱ. According to amino acid residue matching, 7 cases developed de novo antibodies among 92 recipients with 0 HLA-DR mismatches,compared with 59 cases among 292 recipients with 1-2 mismatches, which showed significant difference between two groups (P<0. 01 ). 87. 4 % (278/318) recipients negative for HLA antibodies after transplantation achieved good graft function, in comparison with 65. 2 % (43/66) recipients positive for HLA antibodies (P<0. 05). Conclusion De novo production of HLA antibodies posttransplantation may be closely associated with HLA-DR mismatch. De novo HLA antibodies posttransplantation might damage graft function and reduce graft survival rate. The detection of de novo development of anti-HLA antibodies after renal transplantation has clinical significance for assessing renal allograft function.

Objective To investigate the mechanism of restenosis after carotid stent and balloon angioplasty for the Guangxi swines by intravascular ultrasound(IVUS). Methods Twelve Guangxi swines fed by a high cholesterol diet were randomly divided into two groups. Seven stents were implanted in the left carotid artery of six swines in the first group, and balloon angioplasty was performed in the left carotid artery of swines in the other group. Digital subtraction angiography(DSA) and IVUS were conducted respectively before and after the intervention and in the 13th week. Results IVUS found that the percentage of area stenosis in stent group was (18.31±7.79) % and in balloon group (37.28±7.89) % in the 13th week. The percentage of area restenosis in stent was obviously related to neointimal hyperplasia (r = 0.897, P<0.05), the percentage of area restenosis due to balloon angioplasty was markedly related to area decrease of external elastic lamina (r = 0.856, P<0.05). Conclusions The restenosis in stent was related to intimal hyperplasia of blood vessel,and restenosis after balloon angioplasty had some connection with area decrease of external elastic lamina.

ObjectiveTo summarize the prevention and treatment of complications of carotid angioplasty and stenting (CAS) in the elderly. Methods88 cases (≥60 years) who underwent carotid angioplasty and stenting were collected from our hospital. The prevention and treatment of complications were analyzed retrospectively. ResultsNinety-two self-expanding stents were placed in the 88 cases and the technical success rate was 100%. The degree of stenosis was significantly improved from 82.6% to 13.2%. All patients were followed up for 3-12 months. Carotid sinus reaction was observed in 23 cases (26.1%) and it was more often in ≥70 years group than in 60~69 years group (P<0.05). Meanwhile, compared with the distance >10 mm, Carotid sinus reaition was more often in the distance ≤ 10 mm between carotid bifurcation and maximum stenotic lesion (P< 0.05). Hypertension occurred in 6 cases, cerebral hyperperfusion syndrome in 4 cases including 1 case of cerebral hemorrhage. There were cases with cerebral ischemia in 1 case, cerebralvaseular spasm in 4 cases, acute renal insufficiency in 3 cases and ecchymosis and hematoma at the puncture site in 7 cases. There were 3 cases of transient ischemic attack, 1 case of myocardial infarction, 1 case of cerebral hemorrhage, 2 cases of mild neurological deficits and no death occurred during the period of follow-up. ConclusionsThere is higher risk for elderly patients undergoing CAS, but careful preoperative preparation and properly treatment may avoid the occurrence of complications.

How to identify active constituents of traditional Chinese medicines (TCMs) and study their interactions are key problems in the development of TCMs. The inhibitory effect of six alkaloids from Rhizoma Coptidis (RC) on Shigella dysenteriae (S. dysenteria) growth had been investigated by microcalorimetry in this study. Main active constituents of RC were confirmed by comparing their contributions to the bacteriostatic effect, and the interactions among active constituents were further researched. According to the result, in 0.8 mg-mL-1 extract of RC, the contributions of six active alkaloids including berberine, coptisine, epiberberine, palmatine and the combination of jatrorrhizine and columbamine were 52.83%, 36.31%, 2.49%, 4.27% and 3.21%, respectively. Therefore, berberine and coptisine were the main active constituents of RC that inhibited the growth of S. dysenteria. The study of interactions among the six alkaloids indicated that, 1 there were some contstituents antagonizing the inhibitory effect of RC, 2 there was a synergy effect between berberine and coptisine, 3 there were additive effects between other four alkaloids and the main active constituents. These results may provide some useful references for the establishment of the quality standard for RC and the development of multi-component TCMs.
