Objective:To summarize the experience of reconstruction of mandibular defects with vascularized fibular osteocutaneous flap.Methods:Segmental mandibular resection and immediate reconstruction with vascularized fibular osteocutaneous flap were performed in 8 patients with tumor.The fibula flaps were cut into 2-4 segments and bent to the contour of the mandibles,and they were fixed precisely by the titanium plate.The skin flaps were used for reconstruction of soft tissue defects or as observation windows of the blood circulation.Results:In all 8 patients,transplanted vascularized fibular osteocutaneous flaps survived well,and restoration of mandibular contour and function was satisfactory. Conclusion:The fibular osteocutaneous flap can be cut into segments and shaped according to location and contour of mandibular defect.Vascularized fibular osteocutaneous flap may be an ideal selection for the reconstruction of mandibular defect.

Objective To evaluate the effect of neuromuscular electrical stimulation (NMES) on swallowing function in brain injury patients with dysphagia.Methods Sixty-four patients with dysphagia were divided into A group (n=21,stimulated with T =700 ms,R =2 s,frequency =0.19 Hz),B group (n =22,T =700 ms,R =1 s,frequency =0.29 Hz),and C group (n =21,T =340 ms,R =400 ms,frequency =0.68 Hz).One pair of electrodes was placed at the midline under the chin over the submental muscle group.The intensity of stimulation ranged from 5 to 11 mA.The treatments were once a day,5 times a week,with 20 times as one course.The results were assessed with Kubota's water swallowing test before and 4 weeks after treatment.Results The water swallowing test scores were significantly reduced after treatment in all 3 groups,with significantly greater reductions in A group compared with B and C group.The effectiveness rate was 81％ in A group,73％ in B group and 67％ in C group,all statistically significant differences.Conclusion NMES can be an effective and safe treatment for dysphagia after brain injury.NMES appears to be most effective with T =700 ms,R =2 s,and a frequency of 0.19 Hz.

BACKGROUND:Extradural cortical stimulation combines the advantages of repetitive transcranial magnetic stimulation, transcranial direct current stimulation, subdural cortical stimulation and deep brain stimulation, which can significantly improve motor and language function after stroke. OBJECTIVE:To review the theoretical research and clinical application of extradural cortical stimulation for stroke recovery. METHODS:An online retrieval of PubMed database and CNKI database between January 1995 and April 2014 was performed for articles on theoretical research and clinical application of extradural cortical stimulation for stroke recovery, with the key words of“cortical stimulation, extradural motor cortex stimulation, extradural cortical implants, extradural cortical stimulation, stroke, rehabilitation”in English and Chinese. RESULTS AND CONCLUSION:Because of implantable cortical stimulation, the advantage of extradural cortical stimulation is its minimal invasiveness, high accuracy and transdural contact with the brain. For lack of effective treatment for the chronic phase of stroke patients with motor and language dysfunction, extradural cortical stimulation may be a new therapeutic method. Motor and language functional improvement must derive from reactivation of plasticity, local enhancement of perilesional areas, enhancement of network function and inter-hemispheric balance function, and amplification of sensory input.

Objective To evaluate the effect of sufentanil postconditioning on acetylated histon H3 (Ac-H3) expression during myocardial ischemia-reperfusion (I/R) in rats.Methods Thirty-six adult male Sprague-Dawley rats,weighing 250-300 g,were randomly divided into 3 groups (n =12 each) using a random number table:sham operation group (S group),I/R group,and sufentanil postconditioning group (SP group).Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of the coronary artery followed by 120 min reperfusion in anesthetized rats.Sufentanil 1 μg/kg was injected through the femoral vein at 5 min before reperfusion in group SP,while the equal volume of normal saline was given in S and I/R groups.The rats were sacrificed at 120 min of reperfusion,and the myocardial specimens were obtained from the anterior wall of the left ventricle for determination of myocardial infarct size and cell apoptosis (by TUNEL),and myocardial specimens were obtained from the apex for detection of Ac-H3 expression (using Western blot).Apoptotic index was calculated.Results Compared with S group,the myocardial infarct size and apoptotic index were significantly increased,and Ac-H3 expression was down-regulated in I/R and SP groups (P＜0.05).Compared with I/R group,the myocardial infarct size and apoptotic index were significantly decreased,and Ac-H3 expression was up-regulated in SP group (P＜ 0.05).Conclusion Sufentanil postconditioning attenuates myocardial I/R injury through up-regulating AcH3 expression and restoring histone acetylation in rats.

Hepatic encephalopathy (HE) is caused by severe liver disease or portal shunt. Metabolic disorders and central nervous system dysfunctions are the main symptoms of this syndrome. Ammonia is considered to play a central role in the pathogenesis of HE. Helicobacter pylori (H. pylori) have been suggested as a possible source of ammonia production because of its high urease content. However, the relationship between H.pylori and blood ammonia and HE, as well as the therapeutic effect of H.pylori eradication on HE, is inconclusive, and the results are full of contradictions. The aim of this review is to summarize current knowledge on the association of H. pylori with HE and to address the question of whether H. pylori eradication may be beneficial in the management of HE.

Objective To investigate the effect of suberoylanilide hydroxamic acid (SAHA) on sufentanil postconditioning-induced cardioprotection in rats with type 2 diabetes mellitus (T2DM).Methods Male SPF Sprague-Dawley rats,weighing 250-300 g,aged 5-6 weeks,were used in the study.T2DM was induced by high-fat diet (4 weeks) and intraperitoneal 1％ streptozotocin 35 mg/kg,and confirmed by fasting blood glucose level≥ 16.7 mmol/L.Forty rats with T2DM were divided into 5 groups (n=8 each) using a random number table:sham operation group (grou T2DM-S);ischemia-reperfusion group (group T2DM-I/R);sufentanil postconditioning group (group T2DM-SP);SAHA group (group T2DM-SA);SAHA plus sufentanil postconditioning group (group T2DM-SASP).In T2DM-SA and T2DM-SASP groups,SAHA 25 mg/kg was injected intraperitoneally once a day for 5 consecutive days before operation.Their hearts were excised and retrogradely perfused in a Langendorff apparatus.The hearts were subjected to 30 min of global ischemia followed by 120 min of reperfusion to establish the model of ischemia/reperfusion injury.At 30 min of equilibration and 30,60 and 120 min of reperfusion,the left ventricular systolic pressure (LVSP),heart rate (HR),and the maximum rate of increase and decrease of ventricular pressure (±dp/dtmax) were recorded.At 120 min of reperfusion,the left ventricular mass (LVM) and infarct size (IS) were measured,and IS/LVM ratio was calculated.The expression of glycogen synthesis kinase 3β (GSK-3β) and phosphorylated GSK-3β (p-GSK-3β) in the myocardium was detected by Western blot.Results Compared with group T2DM-S,the LVSP,HR and ±dp/dtmax were significantly decreased,the IS and IS/LVM ratio were significantly increased,and the expression of myocardial p-GSK-3β was significantly down-regulated in group T2DM-I/R (P＜0.05).Compared with group T2DM-I/R,the ±dp/dtmax was significantly increased,the IS and IS/LVM ratio were significantly decreased,and the expression of myocardial p-GSK-3β was significantly up-regulated in group T2DM-SASP (P＜0.05),and no significant change was found in the parameters mentioned above in T2DM-SA and T2DM-SP groups (P＞0.05).Compared with group T2DM-SP,the ±dp/dt was significantly increased,the 1S and IS/LVM ratio were significantly decreased,and the expression of myocardial p-GSK-3β was significantly upregulated in group T2DM-SASP (P＜0.05).Conclusion SAHA can improve cardioprotection induced by sufentanil postconditioning to some extent in the rats with T2DM.

Objective To explore the expression of V-ATPase in colon cancer and its clinical significance. Methods Detecting the expression of V-ATPase mRNA in 20 paired of colon tumor tissues and normal tissues by using reverse transcription-polymerase chain reaction ( RT-PCR) and real-time quantitative polymerase chain reaction( Real-time PCR) , and testing the expression of V-ATPase protein by immu-nohistochemistry of EnVinsion. Results The expression of V-ATPase mRNA in tumor tissues and its paired normal tissues were (5. 37 ± 0. 44) and (2. 03 ± 0. 35)(P<0. 01). The positive immunohistochemistry of V-ATPase in tumor tissues and its paired normal tissues were 69. 1%(47/68) and 5. 8%(4/68) respectively, and the positive expression were primarily in cytoplasm and cytomembrane. Overexpression of V-ATPase was associated with tumor stage (P<0. 05), lymph node metastasis (P=0. 044), distant metastasis (P=0. 049), vessel in-vasion (P=0. 044) and differentiation (P<0. 001). Conclusion Overexpression of V-ATPase plays a significant role in the carcinogene-sis and the progression of colon cancer, which might be an important postoperative therapeutic target.

Objective: To investigate the efficacy and safety of lobaplatin (LBP) plus S-1 for advanced gastric cancer (AGC) and determine the potential role of circulating tumor cells (CTC) for predicting the therapeutic response and prognosis. Methods: From January 2014 to February 2015, 64 consecutive patients with AGC received lobaplatin plus S-1 chemotherapy in Liaocheng People′s Hospital. The clinical features, clinical response, adverse effects, prognosis and CTC pre- and post-treatment were retrospectively analyzed. The correlation between CTC and patients′ disease control rate (DCR), objective response rate (ORR), progression free survival (PFS) as well as overall survival (OS) were investigated. Results: All 64 patients completed 2 cycles of chemotherapy.The number of patients who achieved complete regression, partial regression, stable and progression were 0, 24 (37.5%), 18 (28.1%) and 22 (34.4%), respectively. ORR was 37.5% and DCR was 65.6%. The median PFS was 10.8 months(95%CI 7.1-12.0) and the median OS was 16.1 months(95%CI 12.4-18.8). The ORR and PFS were not significantly different between patients with baseline CTC≥2 and CTC<2 (25.0% vs 53.6%, P=0.150; 6.2 months vs 7.5 months, P=0.780), while the DCR and OS were significantly different (45.9% vs 90.0%, P=0.008; 10.5 months vs 17.2 months, P<0.001). After 2 cycles of chemotherapy, the ORR and DCR in patients with CTC≥2 were 16.7% and 45.9%, respectively, which were significantly lower than those observed in patients with CTC<2 (50.0% and 90.0%, respectively). The former also had shorter median PFS and OS (6.6 months vs 8.9 months, 8.4 months vs 15.0 months, respectively). Patients with persistently CTC<2 or those exhibiting an conversion to CTC<2 following chemotherapy had an improved PFS and OS, while patients with persistently CTC≥2 or those exhibiting an conversion to CTC≥2 following therapy had shorter PFS and OS.The most frequent adverse effects were grade 1 or 2 gastrointestinal discomfort and myelosuppression. No patients discontinued chemotherapy because of adverse events. Conclusions Lobaplatin plus S-1 had manageable safety profile and promising antitumor activity in patients with AGC. CTC could be used as a biomarker in evaluating therapeutic response and predicting their prognosis.
