BACKGROUND:Posterior cervical open-door expansive laminoplasty is one of the simple and effective methods to treat cervical spinal diseases, has satisfactory results but low complications. However, the imbalance of sagittal plan, loss of lordosis or axial pain is often reported recently. OBJECTVE:To analyze the correlation between cervical sagittal alignment and clinical outcomes after laminoplasty. METHODS:Between January 2011 and June 2015, 122 cases of cervical spinal disease, who were treated with open-door expansive laminoplasty with mini-titanium plate, were retrospectively analyzed. Clinical outcomes were evaluated by Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale. Radiographic results were assessed by C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope. The correlation between sagittal alignment and clinical outcomes were analyzed. RESULTS AND CONCLUSION:(1) Al patients were fol owed up for 7-32 months. (2) Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale scores were improved in the final fol ow-up (al P<0.001). No significant difference in upper limb Visual Analogue Scale scores was determined (P=0.142). In the final fol ow-up, C2-7 sagittal vertical axis increased (P=0.036), but neither the C2-7 Cobb angle nor the C7 slope significantly changed (P=0.092, P=0.184). (3) There were no correlations between sagittal alignment parameters (C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope) and clinical outcomes (Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale) (al P>0.05). (4) These findings indicated that posterior cervical open-door expansive laminoplasty with mini-titanium plate can significantly improve the neurological function of patients. However, there is no correlation between cervical sagittal alignment and clinical outcomes.

Objective To observe the effect of low dosage of uhrashortwave(USW) on infarction volume, B cell lymphocytoma-xl (Bcl-xl) and tumor necrosis factor alpha (TNF-?) after cerebral ischemia-reperfusion in rats and discuss its acting mechanisms. Methods Focal ischemia-reperfusion model was established in 25 rats by re- versible right middle cerebral artery occlusion with filament. The right side cerebral ischemia was lasted for 2 hours and then followed with 24 hours of reperfusion. The content of neurological deficits were evaluated by the Zea-Longa 5-degree scoring system to select rats. After surgery, the rats were divided into 3 groups: blank control group, control group and USW treatment group. The brain of all rats was taken at 24 hours after reperfusion. The cerebral infarction volume, the expression of Bcl-xl and TNF-?were measured and analyzed. Results Twenty-five rats were used in the analysis of results. When compared with the control group, the infarction volume and rate in total cerebral volume of USW group significantly decreased (t = 2.54, 2.33, P

BACKGROUNDIt is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.

METHODSWe reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2 ± 12.5) years and the mean left ventricular ejection fraction was (57.4 ± 11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1 ± 11.2) months).

RESULTSFifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n = 7), aortic valve replacement (n = 3), mitral valve replacement (n = 3), mitral valve replacement with coronary artery bypass grafting (n = 1) and left atrial myxoma resection (n = 1). Neoplastic resection consisted of lung cancer resection (n = 5), colonic cancer resection (n = 3), gallbladder resection (n = 1), colonic cancer resection with gallbladder resection (n = 1), hysterectomy (n = 2), hysterectomy with bilateral salpingo-oophorectomy (n = 2) and left ovariectomy (n = 1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).

CONCLUSIONSSimultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality. Cardiopulmonary bypass does not appear to adversely affect survival in patients with malignant disease. The long-term survival was determined by tumor stage.

OBJECTIVETo investigate the feasibility of using cartilage link protein of hyaluronic acid (HA-CLP) for defining the tumor boundary in a mouse model of lung carcinoma.

METHODSLung carcinoma was induced in KM mice by chemical carcinogenesis. HA-CLP separated from bovine cartilage and purified by affinity chromatography was labeled with (125)I for autoradiography. Immunohistochemical analysis and Western blotting were used to examine the efficiency of HA-CLP in defining the boundaries of the lung tumors.

RESULTSWith autoradiography, the clearest image of lung cancer was obtained at 2 h. With immunohistochemical method, the tumor boundary was the most clearly displayed at 2 h when the strongest signals of HA-CLP was detected; Western blotting also showed the clearest bands of HA-CLP at 2 h.

CONCLUSIONHA-CLP has the immunogenicity of HABP, and can efficiently indicate lung tumor boundary in autoradiography and immunohistochemistry.

OBJECTIVETo study the effect of progesterone on matrix metalloproteinase-3 (MMP-3) expression in neonatal rat brain after hypoxic-ischemia.

METHODSFollowed the hypoxic-ischemia of neonatal rat brain, Evans blue (EB) staining and transmission electron microscopy were used to detect the blood-brain barrier pathological changes on permeability. MMP-3 protein expression in cerebral cortex was measured with Western blot.

RESULTSTransmission electron microscopy results showed that the blood brain barrier in hypoxic-ischemic group changed significantly compare to progesterone group. EB staining results suggested that the blood-brain barrier permeability of hypoxic-ischemic group was significantly increased compared to sham-operated group (P < 0.01). The blood-brain barrier permeability in progesterone group was also decreased in comparison to that of hypoxic-ischemic group (P < 0.05). Western blot image analysis results indicated that MMP-3 protein expression in the hypoxic-ischemic group increased significantly than that in sham-operated group (P < 0.01), and the progesterone group was decreased significantly than that in hypoxic-ischemic group (P < 0.05).

CONCLUSIONProgesterone may reduce the blood-brain barrier damage by reducing MMP-3 expression. This might be one of the protective mechanisms in the hypoxic-ischemic brain injury.

Purpose: This study was aimed to evaluate the clinical significance and prognostic value of CRP/albumin ratio (CAR) in patients with gastric cancer. Methods: The data of 205 gastric cancer patients who underwent surgery was analyzed retrospectively. The association of CAR with the clinical features and prognostic value in gastric cancer was analyzed. The data of this study was combined with previous studies to further determine the prognostic value of CAR in patients with gastric cancer using a metaanalysis method. Results: Cox analysis revealed that preoperative CAR was an independent prognosis indicator in patients with gastric cancer. High expression of CAR indicated a shorter survival time than in those with lower expression. CAR has a higher prognostic value in the 1-, 3-, and 5-year overall survival in patients with gastric cancer. CAR showed significant difference regarding the gastric cancer patients’ age, M stage, and clinical stage. The discriminate value of CAR in M stage of gastric cancer was high (area under the curve, 0.809). A meta-analysis combining previous data and our data showed that preoperative CAR demonstrated a significant association with the overall survival of patients with gastric cancer. Conclusion This study demonstrated that preoperative CAR could serve as an important prognostic indicator in patients with gastric cancer.
