Objecive To evaluate and compare the efficacy of injecting tissue glue and lauromacrogol in modified sandwich method combined with synchronous ligation for patients with esophageal and gastric variceal.Methods 42 cases of patients with esophageal and gastric variceal were randomly divided into synchronous treatment group (22 cases) and sequential treatment group (20 cases). Both group received modiifed sandwich method for gastric varices (lauromacrogol-tissue adhesive-lauromacrogol). Synchronous treatment group meanwhile received synchronization ligation for esophageal varices, but sequential treatment group received sequential ligation after one week. The hemostasis rate, effective rate of varices, rebleeding and complications rate were analyzed.Results There were no signiifcant difference in hemostasis rate, effective rate and rebleeding rate between two groups. The incidence of complications, such as chest and abdominal pain, fever, transient bacteremia were equal between these two groups. No patients had ectopic embolism. The number of ligation device in synchronous treatment group was more than sequential treatment group (8.19 ± 2.01 vs 7.81 ± 1.78,P > 0.05), and the rate of esophageal varices disappearance was inferior to sequential treatment group (59.09% vs 70.00%), however, there were no statistical difference (P > 0.05).Conclusion Endoscopic injection of tissue glue and lauromacrogol synchronization ligation is safe and effective for esophageal and gastric variceal with low complication rates. This method could reduce gastroscopy times and medical expenses, and is worthy of further investigating.

Objective To explore the clinical effect of posterior indirect reduction and internal fixation and laminectomy in the treatment of thoracolumbar vertebrae burst fracture complicated with spinal cord injury.Methods Eighty patients with thoracolumbar vertebrae burst fracture and spinal cord injury treated in our hospital from March 2014 to March 2015 were selected as the objects,and they were divided into reset group and laminectomy group with forty cases in each group according to surgical method.All the patients were followed up for 1 year,the lumbar function of two groups at 1 week and 1 year after operation were observed respectively,and the pain degree was observed in 1month,3 months and 6 months after operation.The amount of bleeding,operation time,hospitalization time and fracture healing time were observed.Neurological function was assessed by classification criteria of the American Spinal Cord Injury Association(ASIA),and incidence of complications was figured in the two groups.Results The anterior heights of the injured vertebra were higher than those before the operation,and the Cobb's angles were lower than those before the operation,the differences were significant(P < 0.05);while there was no significant differences in the anterior heights of the injured vertebra between the two groups at 1 week and 1 year after operation(P > 0.05).VAS scores of the two groups after 1 month,3 months and 6 months decreased significantly when compared with the preoperative scores(P < 0.05),and VAS scores of each time in the reset group were significantly lower than those in the laminectomy group(P < 0.05).The amount of bleeding,operation time,hospitalization time and fracture healing time in the reset group were less than those in the laminectomy group (P < 0.05).The neurological function recovery of the two groups were significantly improved when compared with that before the operation(P <0.05).There was no significant difference in recovery of neurological function between the two groups(P > 0.05).The complication rate was 7.50% in the reset group,lower than 12.50% of the laminectomy group,the difference was significant (P < 0.05).Conclusion Posterior indirect reduction and internal fixation of lamina both have a certain effect in the treatment of thoracolumbar vertebrae burst fracture complicated with spinal cord injury.But posterior indirect reduction has less complications and less amount of bleeding,which is beneficial to postoperative recovery.

· AIM: To explore the effects of C3F8 tamponade on hypotony on or after primary operation and the prognosis of severe ocular trauma.· METHODS: Twenty-six cases (26 eyes) of severe ocular trauma were treated with pure C3F8 tamponade on or after primary operation. IOP was observed, and the curative effect of C3F8 tamponade was observed on secondary operation with prognosis evaluated.· RESULTS: Hypotony improved in 23 eyes postoperatively,in which 18 eyes with edematous and cloudy cornea, 15 eyes had clear cornea after gas tamponade. Retina was reattached under the gas action in 21 eyes during the secondary operation. Visual acuity improved in 22 eyes, remained unchanged in 3 eyes and decreased in 1 eye during the follow-up of 3-12months.· CONCLUSION: Application of pure C3F8 tamponade on or after primary operation can effectively improve hypotony after severe ocular trauma and benefit a better prognosis.

To study the effect of miR-490 on Coxsackievirus B3 (CVB3) replication, HeLa cells were trans- fected with miR-490 in vitro, and infected with a Renilla luciferase (RLuc)-expressing CVB3 variant (RLuc-CVB3). The activities of RLuc in these cells were measured at 8h intervals from 0 to 40 h post-infection (p.i.), and the effects of miR-490 on RLuc-CVB3 replication were observed. In a further study, HeLa cells were transfected with either miR-490 or antisense miR-490 (AMO-miR-490), and were then infected with an enhanced green fluorescence protein (EGFP)-expressing CVB3 variant (EGFP-CVB3). The replication of EGFP-CVB3 was then determined by detecting the expression of EGFP. We observed that miR-490 could significantly inhibit the expression of RLuc in infected cells at 32 h p. i. Furthermore, in HeLa cells infected with EGFP-CVB3 at 32 h p.i., EGFP expression was also significantly inhibited by the presence of mniR-490. The inhibitory effect of miR-490 on EGFP expression in EGFP-CVB3-infected cells could be reversed by tranfection with AMQ-miR-490. These results indicated that miR-490 significantly inhibits the replication and expression of QVB3.

To investigate the biological role of snake venom cystatin(sv-cystatin) in tumor progression, the cDNA of sv-cystatin amplified by PCR from pUC18-cystatin plasmid was cloned into methanol-inducible expression vector pPICZ?A. The linearized recombinant plasmid pPICZ?A-cystatin was transfered into Pichia pastoris, strain GS115 by electrophoration. Transfermants with phenotype Mut+ selected were identified by PCR analysis and induced in 1.0% methanol. The reombinant sv-cystatin protein was examined by SDS-PAGE, Western blot analysis. The molecular mass of expression product was about 14 kDa and approximately 16 mg/L of recombinant sv-cystatin was produced from one of GS115-cystatin transformants. The chromatography purified protein could reduce the activity of papain. The ability of B16F1 cells treated with recombinant sv-cystatin to invade the reconstituted basement membrane decreased significantly (P

MAIN OUTCOME MEASURES: Free running EMG and stimulus triggered EMG, including time, frequency, amplitude, muscle group were observed and recorded simultaneously. Never root functional injury and restoration after surgery were detected.RESULTS: 378 pedicle screws in 74 patients were monitored intraoperatively, and only 3 pedicle screw malposition (2 of L_4, 1 of L_5) was detected and then replaced with the help of C-arm fluoroscopic examination. Myoelectricity appeared when the current intensity was less than 10 mA. The correct rate of implantation was 99.2%. Nerve root impingement was found in two cases during laminectomy for L_5 and S_1 decompression and never root solution, which alerted the surgical team of critical neural structures. Nerve symptoms of the lower limb were aggravated after surgery and restored following 2-4 weeks of conventional treatment. The error injury rate of nerve root was 2.7%. In all reported cases, no irreversible neurological deficit was observed 2-4 weeks after operation.CONCLUSION: Intraoperative EMG monitoring can find improperly placed screws and detect impending nerve root injury promptly. Combined EMG and 3-D imaging modality monitoring is a reliable and practicable method that can be used to protect neural structures during complex lumbosacral surgery.
