In this paper, the function of the iel gene from baculovirus Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV), belonging to group Ⅱ nucleopolyhedrovirus, was studied in mammalian cells.We amplified the SeMNPV ie1 gene and expressed it by fusing to the C terminal of enhanced GFP protein in HEK 293 cells. Confocal microscopy revealed that the IE1-GFP fusion protein was localized in the nucleus of the mammalian cells. The promoter sequences of AcMNPV gp64, SeMNPV F protein and Drosophila hsp70 were also analyzed, to further study the function of SeMNPV IE1. The results showed that, in the absence of the hr sequence, IE1 improved the expression of the F promoter but didn't influence the gp64 promoter significantly, but IE1 moderately stimulated the hsp70 promoter.

Objective To observe the effects of hyperbaric oxygen therapy(HBOT) on Glasgow coma scale(GCS) in patients with traumatic brain injury(TBI) and the influences of course and initiating time of HBOT on the therapeutic effects.Methods 105 cases of TBI patients,which performed HBOT more than 30 days in HBOT Center of Southwest Hospital,were analyzed retrospectively.The GCS improvements were compared with 29 cases of TBI patients without HBOT during the same period.They were also compared between patients with different severity,initiating times and courses of HBOT.Results The GCS improvement of patients with HBOT was 3.97?2.65,especially in severe TBI patients(5.22?2.49),Both were higher than that without HBOT(2.38?2.16)(P

AlM: To analyze, summarize and describe ophthalmic imaging features of posterior scleritis.
METHODS: Clinical data of 16 patients ( 21 eyes ) with posterior scleritis diagnosed in our hospital from October 2008 to June 2013 were retrospectively analyzed. The results of type-B ultrasonic, fundus chromophotograph, fundus fluorescein angiography, CT were recorded for comprehensive evaluation and analysis of ophthalmic imaging features of posterior scleritis.
RESULTS: All patients underwent type-B ultrasonic examination and manifested as diffuse and nodular types. The diffuse type showed diffusely thickened sclera and a dark hypoechoic area that connected with the optic nerve to form a typical “T”-shaped sign. The nodular type showed scleral echogenic nodules and relatively regular internal structure. FFA showed that relatively weak mottled fluorescences were visible in the arterial early phase and strong multiple needle-like fluorescences were visible in the arteriovenous phase, which were then progressively larger and fused; fluorescein was leaked to the subretinal tissue in the late phase;varying degrees of strong fluorescences with less clear or unclear boundaries were visible in the optic disk. CT results showed thickened eyeball wall.
CONCLUSlON: Posterior scleritis is common in young female patients, whose ophthalmic imaging features are varied and more specific in type-B ultrasonic. Selection of rational ophthalmic imaging examination method, combined with clinical manifestations, can accurately diagnose posterior scleritis and avoid the incidence of missed and delayed diagnosis.
4.Clinical value of tunnel endoscopy for the treatment of esophagogastric diseases.
Chinese Journal of Gastrointestinal Surgery 2012;15(7):659-661
Tunnel endoscopy is a new therapeutic technique developed from natural orifice endoscopic transluminal surgery and endoscopic submucosal dissection. With the quick development in the passing 5 years, tunnel endoscopy has been applied in the treatment of clinical diseases. In this article, our aim was to clarify the indication and method, evaluate the efficacy and safety of tunnel endoscopy for the treatment of esophagogastric diseases, including esophageal achalasia and submucosal tumors originating from the muscularis propria layer.

AIM: To investigate the relationship between the protective effect of sodium oxybate on neuronal damage induced by hypoxia reoxygenation and GABA A receptor in primary cultured rat cortical neurons. METHODS: The primary cultured rat cortical neurons were used to make the hypoxia reoxygenation damage model. The morphology of cell was observed. The lactate dehydrogenase (LDH) effluxed into the media as an indicator of neuronal injury was detected after 6 h of the reoxygenation injuries. The malonyldialdehyde (MDA) contents, superoxide dismutase (SOD) and glutathione peroxidase (GPX) activities were determined at the same time. RESULTS: The hypoxia reoxygenation caused neuronal swelling and widespread neuronal degeneration, increased LDH efflux and MDA contents, and decreased SOD and GPX activities. Sodium oxybate assuaged neuron damage, decreased LDH efflux and MDA contents (P

Objective To study the role of CT in the evaluation after patellar dislocation triple surgeries.Methods Retrospectively analysed the CT measurements of 60 recurrent patellar dislocation patients (61 knees),who had undergone patellar dislocation triple surgeries,within one month before and after procedures.The measurements included patellar tilt angle,lateral patellar displacement,trochlear con-gruence angle,Tibial Tuberosity-Trochlear Groove distance,Insall-Salvati Ratio and Caton-Deschamps Index.Moreover,the troch-lear dysplasia classifications of all patients were evaluated.In addtion,an analysis has also been completed for 40 (41 knees)of 60 patients who had second postoperative CT examinations as follow-up assessment 3 to 6 months after surgeries.Results All one-month postoperative measurements decreased obviously with statistical significance(P <0.05 ).Furthermore,one case of subluxa-tion,1 1 cases of abnormal Tibial Tuberosity-Trochlear Groove distance,13 cases of abnormal Insall-Salvati Ratio and 14 cases of Ca-ton-Deschamps Index abnormities were also observed.Besides that,it was also found that all patients had trochlear dysplasia and 5 cases were diagnosed with patellar subluxation or dislocation at the second postoperative follow-up assessment.Conclusion The patients with redislocation or risks for patellar instability can be detectecd by CT which provides objective evidence for postoperative evaluation and further treatments.

AIMTo study the protective effect of sodium oxybate (SO) against focal cerebral ischemia-reperfusion injury in rats, and the relationship between the effects of SO and ?-aminobutyric acid (GABA). METHODSThe reversible middle cerebral artery occlusion (MCAO)model in rats was established to investigate the role of SO. The scores of neurological deficits was detected by Longa EZ method in MCAO rats. The extracellular levels of glutamate (Glu) and GABA in CSF were measured by high performance liquid chromatography-fluorometer (HPLC-FR) method, and the weight of cerebral infraction was detected. RESULTSThe scores of neurological deficits and the weight of cerebral infraction markedly decreased by SO while the ratio of GABA/Glu obviously increased administered SO in MCAO rats. CONCLUSIONSSO could prevent MCAO rats from ischemia-reperfusion injury, the protective effect is related to SO keeping dynamic balance of excition-inhibition, and persisting inhibition-depended effect.
