Osteogenesis and expression of bone morphogenetic protein 2 after bone marrow mesenchymal stem cells combined with calf cortical bone with partial cancellous bone implanted into rabbits / 中国组织工程研究

BACKGROUND: Previous studies have confirmed that rabbit bone marrow mesenchymal stem cells (BMSCs) can differentiate into osteoblasts under osteogenic induction in vitro, stably express the specific phenotype of osteoblasts and have osteogenic ability. Calf cortical bone scaffold with partial cancellous bone has good biocompatibility and degradability, which can be used as a carrier material of bone marrow mesenchymal stem cells. OBJECTIVE: To combine rabbit BMSCs with calf bone composite according to the basic principles of bone tissue engineering and to observe the osteogenesis in the New Zealand white rabbits after implantation of BMSCs/calf bone composite into the ilium, thereby providing a direct evidence for preliminary clinical application of tissue-engineered bone products.METHODS: BMSCs/calf cortical bone scaffold with partial cancellous bone (tissue-engineered bone group), simple calf heterogeneous bone (heterogeneous bone group) or autologous iliac bone (autologous iliac bone group) was randomly implanted into the rabbit ilium. The changes of implant surface and tissue reactions around the implant were observed.X-ray examination was performed to observe osteogenic changes at 4, 8, 12, 24 weeks after implantation. Immunohistochemistry staining was used to observe the expression of bone morphogenetic protein 2.RESULTS AND CONCLUSION: After heterogeneous bone implantation, the wound healed well, and there were no systemic or local inflammation and toxicity reactions in all groups. The X-ray results showed that at postoperative 24 weeks, the implant was basically fused with the host bone in the tissue-engineered bone group, but the fusion was unsatisfactory in the heterogeneous bone group. The process of ossifications from cartilages was observed in all groups by hematoxylin-eosin staining, and bone morphogenetic protein 2 was positive for immunohistochemical staining. Findings from in vivo experiments indicate that rabbit BMSCs seeded onto the calf cortical bone scaffold with partial cancellous bone could construct tissue-engineered bone by osteoinductation in vitro in the rabbits.

Strengthen perioperative multimodality treatment in order to improve long-term outcomes of esophageal cancer / 中华胃肠外科杂志

Esophageal squamous cell carcinoma (ESCC) is one of the commonest malignancies in China. Surgery is the main treatment for ESCC. However, the long-term survival is very poor by surgery alone. Perioperative multimodality treatment, including locally and systemically administrated, preoperatively and postoperatively, has been and will be the standard treatment in terms of improving long-term survival. Base on decades of practice and clinical trials, it is believed that preoperative treatment is better than postoperative treatment, and that chemotherapy plus radiotherapy preoperatively is better than either chemotherapy or radiotherapy alone. Therefore, preoperative radiochemotherapy followed by surgery is the standard treatment and future direction for locally advanced ESCC.

Risk factors analysis of nonalcoholic fatty liver disease in Chinese men / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To explore risk factors of nonalcoholic fatty liver disease (NAFLD) in men in order to provide a theoretical basis for developing more effective NAFLD prevention and control strategies.</p><p><b>METHODS</b>One-hundred-and-two male patients (37.3+/-11.4 years old) hospitalized with NAFLD at the Dongnan Affiliated Hospital of Xiamen University between January 2009 and December 2010 were enrolled in the study, along with 23 age-matched healthy men (34.4+/-16.7 years old) to serve as the control group. The correlation(s) of body mass index (BMI; overweight defined as more than or equal to 22.717 kg/m2), waist circumference (WC), waist-to-hip ratio (WHR; central obesity defined as more than or equal to 0.866), fasting plasma glucose (FPG), triglyceride (TG), and total cholesterol (TC) with NAFLD was analyzed by univariate and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curves were used to select proper thresholds for classification.</p><p><b>RESULTS</b>BMI, WC, WHR, FPG, TG, and TC were significantly different between the cases and controls (P less than 0.01). BMI, WC, WHR, TG and TC were identified as risk factors of NAFLD in these male cases (P less than 0.01). Relative to WC, TG and TC, both BMI and WHR had significant predictive value for NAFLD (odds ratio (OR) = 10.819 and 10.588, respectively). In addition, BMI had the highest diagnostic value for the prediction of NAFLD (area under the curve (AUC) = 0.931) followed by WHR (AUC = 0.879).</p><p><b>CONCLUSION</b>BMI, WC, WHR, TG, and TC are risk factors of NAFLD in Chinese men. BMI and WHR are effective anthroposomatology indices of NAFLD and may be useful factors on which to base future prevention and early diagnosis strategies for NAFLD in males.</p>

Research progress of prognostic protein biomarkers associated with esophagus squamous cell carcinoma / 中华胃肠外科杂志

Esophageal cancer (EC) is one of the common malignant tumors in China. Esophagectomy based on multi-disciplinary principle improves the quality of life and survival of esophageal cancer patients, but a lot of patients will suffer recurrence or metastasis after surgery. TNM stage is the most important factor which affects the prognosis of patients with esophageal cancer. Besides, there are other prognostic factors, such as abnormal expression of the proteins. Exploration of these proteins may provide new clues to improve prognosis in esophageal squamous cell cancer (ESCC). We reviewed the literatures related to abnormal protein expression in ESCC, and tried to elucidate the prognostic value and potential clinical application of these proteins in ESCC.

One hundred years of evolution of esophageal surgical approach and clinical significance / 中华胃肠外科杂志

Esophageal surgery has developed for almost 100 years. Esophagectomy can be performed via left, right thoracotomy, even via hiatus without thoracotomy due to its unique anatomic characteristics. Left thoracotomy was the initial approach in the world, and has still been performed by Chinese colleagues, but Ivor Lewis (right side thoracotomy) procedure is popular in western countries. Currently, esophagectomy by right thoracotomy has been accepted worldwide since its radical dissection for tumor. Therefore, video-assisted thoracoscopic esophagectomy based on right thoracotomy will be the mainstream surgery for esophageal cancer in the future since its minimal invasion and tumor dissection.

Protection on intestinal mucosa barrier during perioperative period of esophageal cancer / 中华胃肠外科杂志

Intestinal mucosa plays important roles in digestion, absorption and substance exchange between organism and external environment. Meanwhile, it is the largest immune organ and mucosal barrier, including mechanical, biological and immune barrier. A variety of diseases, especially postoperative complications, are associated with the damage of mucosal barrier. Esophageal cancer surgery is complex and many perioperative factors, especially hypoperfusion and fasting, may affect the integrity of intestinal barrier. Understanding of the mechanism of intestinal barrier (mechanical, biological and immune barrier), the physiological function of probiotics, and the benefit of early enteral nutrition to intestinal barrier are important components to achieve fast recovery after surgery for esophageal cancer.
