Abstract
Interferon (IFN) is a vital antiviral factor in host in the early stages after the viral invasion. Meanwhile, viruses have to survive by taking advantage of the cellular machinery and complete their replication. As a result, viruses evolved several immune escape mechanisms to inhibit host IFN expression. However, the mechanisms used to escape the host's IFN system are still unclear for infectious hematopoietic necrosis virus (IHNV). In this study, we report that the N protein of IHNV inhibits IFN1 production in rainbow trout by degrading the MITA. Firstly, the upregulation of IFN1 promoter activity stimulated by poly I:C was suppressed by IHNV infection. Consistent with this result, the overexpression of the N protein of IHNV blocked the IFN1 transcription that was activated by poly I:C and MITA. Secondly, MITA was remarkably decreased by the overexpression of N protein at the protein level. Further analysis demonstrated that the N protein targeted MITA and promoted the ubiquitination of MITA. Taken together, these data suggested that the production of rainbow trout IFN1 could be suppressed by the N protein of IHNV via degrading MITA.

Abstract
BACKGROUND Due to its anatomical features, the vertebrobasilar artery complex (VBA) seldom contributes to the neurovascular conflict in patient with trigeminal neuralgia (TN). However, once it offends the trigeminal root, this large artery is really difficult to manipulate during microvascular decompression (MVD) surgery. Therefore, the surgical strategy for such cases needs to be detailed in order to obtain a satisfactory outcome. METHODS From 2009 through 2011, 475 consecutive TN patients underwent MVDs in our department. Among them, ten were found in which an ipsilateral deviating ectatic vertebrobasilar artery complex (VBA) offended the trigeminal nerve. Those cases were focused on in this study and each operation was analyzed retrospectively. RESULTS During the operation, the vertebral artery was regarded as the direct culprit in six (60 %) patients, while the basilar artery in four (40 %). As companions, some smaller vessels were also observed to be close to the nerve, including the superior cerebellar artery (SCA) in five, veins in two and anterior inferior cerebellar artery (AICA) in two. The neurovascular conflict was discovered in the cisternal segment of the trigeminal root in eight, while in the root entry zone (REZ) in two. In six out of the ten cases, the affected nerves were demonstrated to be squeezed towards the tentorium by the ectatic VBA. Postoperatively, the symptom of pain totally disappeared immediately in eight (80 %) patients, while it was relieved apparently in two (20 %). During the follow-up period of 3-30 months, no recurrence or complication was found, except for one patient who had numbness of the face. CONCLUSION With a proper strategy, MVD is probably the most effective therapy for the TN cases caused by ectatic vertebrobasilar artery complex. The substance of the surgery is to withdraw the proximal vertebral artery caudally via a lateroinferior cerebellar approach.

Abstract
Abstract
BACKGROUND:
Although microvascular decompression (MVD) is widely accepted as the effective therapy for hemifacial spasm (HFS) or trigeminal neuralgia (TN), the surgical treatment of coexistent HFS and TN in an individual is seldom addressed.
OBJECTIVE:
To discuss the operative strategy of MVD for both the hemifacial and trigeminal nerves.
METHODS:
Nine consecutive cases of coexistent HFS and TN caused by neurovascular confliction in the same side were studied. Except for one, the patients suffered from HFS followed by ipsilateral TN. All patients underwent MVD and were followed up for 3 to 30 months. Each surgery was analyzed retrospectively.
RESULTS:
Intraoperatively, a looped vertebral artery (VA) shifted to the suffered side was found in 8 patients. The VA was regarded as the direct or indirect offending artery. After MVDs, the spasm ceased immediately in 6 patients; the other 3 patients had delayed relief within 3 months. The pain disappeared immediately in 7 of 9 patients. One patient felt relief after a week, and 1 had pain but improved slightly. No recurrence or complication was found.
CONCLUSION:
A shifted VA loop may account for this tic convulsif syndrome. MVD is a reasonable and effective therapy with a high cure rate for the disease. The key to the surgery is to move the VA proximally. The dissection should be performed rostrally starting from the caudal cranial nerves.

Abstract
OBJECTIVE The root exit zone (REZ) of the seventh cranial nerve has been the target of microvascular decompression surgery (MVD) while searching the neurovascular conflict for treatment of hemifacial spasm for long time. Recently, increasing cases regarding the offending vessel beyond the REZ have been reported. To verify whether a thorough dissection of the nerve may give rise to a better postoperative result without enhancing complications, we conducted a parallel investigation. PATIENTS AND METHODS 112 Connective entire-nerve-exposed MVDs were performed and compared to 186 REZ-exposed MVDs performed by the same group of surgeons in 2009. The surgical findings, postoperative outcomes and complications as well as microscopic operating time were examined. RESULTS Immediately after the surgery, the outcomes were excellent in 98.2%, good in 1.8% and poor in 0% in the entire-nerve-exposed group, compared to excellent in 92.5%, good in 1.6% and poor in 5.9% in the REZ-exposed group. The difference of outcomes between the two groups were statistically significant (χ(2)=4.6845, P=0.0304), but not the complications and microscopic operating time. Nine of the 11 poor-outcome patients from the REZ-exposed group were then reoperated on within a few days, and their symptoms disappeared in eight patients. The main reason for the failed surgeries was that the offending vessels beyond REZ were missed. CONCLUSIONS These findings suggested that the entire-root-decompression technique is recommended while performing MVDs in patients with hemifacial spasm.

Abstract
Pb3 (po4)2-precipitation was used to study the ATPase activities both in fertile and sterile anthers of rice (Oryza sativa L. cv. Marxie). At big-vacuole pollen stage, tapetum of the fertile anthers showed high ATPase activity in their nuclei. In fertile pollen, ATPase was localized on the outside surface of the exine and in the nucleus both at big-vacuole and at bi-nucleate pollen stage. At late bi-nucleate pollen stage, a large amount of Pb3 (PO4)2 precipitated in endintine of the fertile pollen. In sterile anthers, tapetum was fully degenerated at big-vacuole pollen stage. In sterile pollen, ATPase was localized both on the plasmamembrane and in intine. These phenomena lasted to the bi-nucleate pollen stage. In addition, most of the sterile pollen did not show well-developed endintine. Based on the above results, we suggested that abortive tapetum could not provide enough nutrition for pollen development, and the high ATPase activity both on plasma membrane and in intine would likely result in ATP shortage in sterile anthers.

Abstract
A CMS line specific mtDNA band TA1 was isolated by comparing the mtDNAs of CMS line and maintainer line using AFLP technique. The Northern blot analysis of the TA1 mtDNA fragment show that it transcripts only one RNA molecular each in CMS line, maintain line and the first filial generation, but the RNA moleculars are different among each other. By sequencing, the fragment is found to be 202 base pairs in length. It contains code ATG, ATT, AGA and AGG, two small repeated sequences 5'TGTAC3' and 5'ATTATTTT3' and one small inverted-repeated sequence 5'GGGAAACA3'. The results imply that the mtDNA fragment may be a coding region and may be relative to CMS of Hong Lian type rice.
