Grass carp reovirus (GCRV), a disaster agent to aquatic animals, belongs to Genus Aquareovirus of family Reoviridea. Sequence analysis revealed GCRV genome segment 8 (s8) was 1296 bp nucleotides in length encoding an inner capsid protein VP6 of about 43kDa. To obtain in vitro non-fusion expression of a GCRV VP6 protein containing a molecular of fluorescence reporter, the recombinant baculovirus, which contained the GCRVs8 and eGFP (enhanced green fluorescence protein)genes, was constructed by using the Bac-to-Bac insect expression system. In this study, the whole GCRVs8 and eGFP genes, amplified by PCR, were constructed into a pFastBacDual vector under polyhedron (PH) and p10 promoters, respectively. The constructed dual recombinant plasmid (pFbDGCRVs8/eGFP) was transformed into DH10Bac cells to obtain recombinant Bacmid (AcGCRVs8/eGFP) by transposition. Finally, the recombinant bacluovirus (vAcGCRVs8/eGFP) was obtained from transfected Sf9 insect cells. The green fluorescence that was expressed by transfected Sf9 cells was initially observed 3 days post transfection, and gradually enhanced and extended around 5days culture in P1(Passage1) stock. The stable high level expression of recombinant protein was observed in P2 and subsequent passage budding virus (BV) stock. Additionally, PCR amplification from P1 and amplified P2 BV stock further confirmed the validity of the dual-recombinant baculovirus. Our results provide a foundation for expression and assembly of the GCRV structural protein in vitro.

AIM:To explore the differences between unilateral recess-resection (R & R) and bilateral lateral rectus recession (BLR-rec) in the treatment of basic intermittent exotropia.METHODS: A retrospective analysis of treatment of basic intermittent exotropia in 89 patients,in which 49 cases underwent unilateral recess-resection,40 cases underwent bilateral lateral rectus recession of external rectus retroperitoneal surgery January 2013 to January 2015 in our hospital.The stereopsis and strabismus were observed in 1d,1,6mo,1 and 2a after operation.RESULTS: There was no significant difference in the success rate and oblique degree between the two groups after 1d,1,6mo,1 and 2a (all P>0.05),but the success rate of the operation was reducing as time passed.After 2d of the operation,the drift of the R & R group was 12.10±5.74PD and the drift of the BLR-rec group was 7.78±4.21PD,the difference was statistically significant (P=0.021).The R & R group was more likely to cause lateral slanting than BLR-rec group.Two groups of patients with nearly stereopsis were both significantly improved,there was no significant difference between the two groups in the two groups (x2=4.530,P=0.210).CONCLUSION: The long-term stability of BLR-rec is superior to R & R.

Objective To assess left ventricular (LV) global systolic function in patients with essential hypertension with normal geometric LV by 3-dimensional ultrasound speckle tracking imaging(3D-STI). Methods Fifty patients with essential hypertension were enrolled in this study, 29 normal subjects matched with age and sex were selected as control groups. LV global longitudinal peak systolic strain (GLS), radial peak systolic strain (GRS), circumferential peak systolic strain (GCS), LV global 3-dimentional radial peak systolic strain (3DGRS) were measured in all subjects by 3D-STI from the apical full-volume image and compared between groups. LV ejection fraction (LVEF) was acquired from 3D-STI.Results Compared with controls, LV GLS, GRS, GCS and 3DGRS were significantly reduced in patients with hypertension ( P ＜ 0.05 for all). A Pearson correlate revealed that LV GCS, GLS and GRS corresponded with LVEF( r1 =0.930, P1 ＜0.001; r2 = 0.705, P2 ＜0.001; r3 =0.474, P3 =0.001,respectively) in patients with hypertension, and LV GCS, GLS correlated with LVEF( r1 = 0. 838, P1 ＜0. 001; r2 = 0. 697, P2 ＜ 0. 001, respectively) in normal subjects. Conclusions LV global 3D strain decreases in patients with hypertension in the early period,3D-STI could evaluate the early change of heart function in patients with hypertension. LV circumferential movement plays a major role in the LV 3D movement and impacts on LVEF.

AIM:To investigate the expression of angiotensin-converting enzyme 2 (ACE2) in nephritic epithelium of primates. METHODS:The expression of ACE2 in Vero E6 cells was detected by the techniques of RT-PCR and immunocytochemistry (ICC) techniques. The distribution of ACE2 protein in kidney tissues of two Rhesus monkeys and two normal human cases was observed by immunohistochemistry (IHC) techniques. RESULTS:Vero E6 cells were found to express both ACE2 mRNA and protein. ACE2 protein was mainly located in epithelium of proximal tubules of Rhesus monkey and human kidney. CONCLUSION:The expression of ACE2 in epithelium of primate kidney may provide the condition for SARS-CoV entry,which may be one of the reasons for inducing renal damage in SARS patients.

OBJECTIVETo investigate the effect of hydrogen sulfide (H2S) on mitochondrial function in acute myocardial ischemia in rats.

METHODSAcute myocardial ischemia models were established by ligating the left anterior descending coronary artery (LADC) of rats. Fourty-eight male SD rats were randomly divided into 6 groups (n = 8): sham operation group, ischemia group, ischemia + sodium hydrosulfide (NaHS) low, middle and high dose groups and ischemia + DL-proparglycine(PPG) group. The ultrastructures of myocardial mitochondria were observed with electron microscope. The content of H2S in plasma and the activity of cystathionine-gamma-lyase (CSE) in myocardial tissue of rats were respectively detected. The swelling and activity of myocardial mitochondria were determined. The activities of ATPase, GSH-Px, SOD and the content of malondial-dehyde (MDA) in myocardial mitochondria of rats were also measured.

RESULTSCompared with those of the sham operation group, the content of H2S in plasma, the activity of CSE in myocardial tissue and the activity of myocardium mitochondria were significantly decreased. The activities of ATPase, SOD, GSH-Px in myocardial mitochondria were significantly decreased, The content of malondial dehyde(MDA) in myocardial mitochondria and the swelling of mitochondria were distinctly increased in the ischemia group (P < 0.01). Compared with those of the ischemia group, the content of H2S in plasma and the activity of CSE in myocardial tissue were increased, and the activities of mitochondria, ATPase, SOD, and GSH-Px in myocardial mitochondria were significantly increased in ischemia + NaHS low, middle and high-dose groups; the swelling of mitochondria and the content of MDA in myocardial mitochondria were significantly decreased in ischemia + NaHS middle and high-dose groups (P < 0.05 or P < 0.01). The administration of PPG could partially reduce the myocardial protection of hydrogen sulfide (P < 0.05 or P < 0.01).

CONCLUSIONIt could be concluded that the administration of hydrogen sulfide could enhance the activities of mitochondrial ATPase, SOD, GSH-Px, decrease the level of mitochondrial lipid peroxidation, and play a protective effect against acute myocardial ischemia.

Objective To explore the association of interleukin (IL)-1 genotypes with Alzheimer′s disease (AD). Methods Using polymerase chain reaction and restriction fragment length polymorphism, the IL-1A (-889) and IL-1B (+3953) genotypes in 84 cases of AD and 139 controls were detected and analyzed. Results The frequencies of IL-1A(- 889) C/C, C/T and T/T genotypes were 72.6% and 84.2%, 23.8% and 14.4%, 3.6% and 1.4% in AD cases and controls respectively. The genotypes frequencies of IL-1A (-889) C/C, C/T and T/T in AD cases were similar to that of controls (χ2=4.53, P＞0.05), but the frequencies of IL-1A (-889) T allele were significantly higher in AD cases than in controls (15.5% vs. 8.6%, χ2=4.93, P＜0.05). The frequencies of IL-1B (+3953) C/T genotypes and T allele were also significantly higher in AD cases than in controls (16.7% vs. 6.5%, 8.3% vs. 3.2%, χ2=5.88,5.56, both P＜0.05). Conclusions IL-1 genotypes are associated with AD. IL-1 genotypes may play an important role in the development of AD.
