Background and purpose:The morbidity and mortality of lung cancer are currently the highest malignant tumor in China and the world. Most onset age of the illness is after 60 years old. Therefore, surgical resection of lung cancer in the elderly is very worthy of concern. This study aimed to investigate the clinical features, epidemic characteristics and conditions in perioperative period between the elderly and middle-aged patients with lung cancer, and provide the reference for clinical treatment.Methods:Totally 1 019 patients with lung cancer who were admitted to the hospital and accepted the operations in department of thoracic surgery in Shanghai Pulmonary Hospital from Jan. 2007 to Dec. 2012 were analysed retrospectively. The clinical data including gender, pathological type, TNM stage, intraoperative amount of bleeding and post-operative length of hospitalization were compared.Results:There was a signiifcant difference in sexual factors between these two groups (P?0.05), and compared with the middle-aged group, the proportion of male was more higher in the elderly group (76.91%vs 52.81%). Adenocarcinoma was the most common and squamous carcinoma was the next in both two groups. The constituent ratio of the pathlogical type between the elderly group and the middle-aged group was statistically signiifcant (P?0.05). The squamous carcinoma in the elderly group was higher than that in the middle-aged group (37.5%vs 15.6%). On the contrary, adenocarcinoma was more common in the middle-aged group (72.8%vs 50.7%). StagesⅡa,Ⅱb, andⅢa were more common in the elderly group and stagesⅠa, andⅠb were the most clinical stage in the middle-aged group. The clinical stage between two groups was statistically significant (P?0.05).The intraoperative amount of bleeding was higher and the post-operative length of hospitalization was longer in the elderly group, with a signiifcant difference as compared with that in the middle-aged group(P?0.05). And there was a signiifcant difference in incidence of accompanying diseases between the two groups, compared with the middle-aged group, the proportion of accompanying diseases was more higher in the elderly group(58.6%vs42.3%).Conclusion:Elderly patients with lung cancer are more common in males, with adenocarcinoma being the most common. The cancer mostly belongs to a medium or advanced stage. Elderly patients have the trend with more amount of bleeding in operation and lengh of stay.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.

Objective To explore the expression and regulatory mechanism of hypoxia inducible factor-1?(HIF-1?)during fracture healing. Methods Mouse models of tibia fracture healing were established,and callus samples were collected 1,3,7,14,21 and 28 days after fracture.The development of callus and new bone formation were evaluated with roentgenology,Micro-CT and tetracycline double labeling method,and the expression of HIF-1?,vascular endothelial growth factor(VEGF),Runx2 and ALP in callus were detected with RT-PCR,Western blotting and immunohistochemistry.The relationship between HIF-1? and fracture healing was analysed. Results The expression of HIF-1? was detected in cells in the fracture sites as well as in evolved osteoblasts,chondrocytes and osteocytes in early callus under hypoxia.The highest expression rate of HIF-1? achieved on the 7th day after fracture,lasted for about 7 days,then decreased gradually,and returned to intact level on the 28th day after fracture.The expression tendency of VEGF resembled that of HIF-1?.Bone formation activity was more active in early callus,and the callus volume peaked on the 14th day after fracture and decreased gradually.The mineralization of callus mainly took place in the late healing period(14th to 28th day after fracture).Conclusion Cells involved in fracture healing are hypoxia-responsive cells,which express HIF-1?.HIF-1? can regulate cell state and function,and can promote angiogenesis so as to play a crucial role in fracture healing.

BACKGROUND:Anterior cruciate ligament (ACL) injury is a commonly sport-induced knee joint injury that does serious harm to the knee stability. ACL reconstruction is a commonly used treatment method, but researches on 1/2 peroneus longus tendon (PLT) graft are rarely reported. OBJECTIVE: To investigate the clinical outcomes of removing the autologous ipsilateral 1/2 PLT under arthroscopy for ACL reconstruction. METHODS:106 patients with complete ACL rupture in the Affiliated Hospital of Traditional Chinese Medicine, Southwest Medical University from December 2010 to December 2014 were enrolled, and autologous ipsilateral 1/2 PLT was removed under arthroscopy for ACL reconstruction. At baseline, 3, 6 and 12 months postoperatively, the knee stability was evaluated manually through the anterior drawer test, Lachman test, and pivot-shift test, and the knee function was evaluated by Tegner activity scale, Lysholm and International Knee Documentation Committee scores. RESULTS AND CONCLUSION: Postoperative anterior drawer test, Lachman test, and pivot-shift test tests were negative in all patients. In terms of Tegner activity scale, Lysholm and International Knee Documentation Committee scores, there were significant differences at baseline and postoperative 3 months as compared with postoperative 6 months (P < 0.05); the scores at baseline and postoperative 3 months showed significant differences compared with 12 months postoperatively (P < 0.05); the scores showed no significant difference between 6 and 12 months postoperatively (P > 0.05). These results indicate that autologous ipsilateral 1/2 PLT is a good choice for ACL reconstruction under arthroscopy, achieving rapid and satisfactory functional recovery of the knee joint, which is not only minimally invasive and easy to operate, but also exhibits good therapeutic efficacy.

Objectiye To observe the prevalence of prolonged seizures and the changes of biochemical markers of myocardial injury in patients with prolonged seizures after modified electroconvulsive therapy(MECT).Methods Patients treated with MECT or simulated ECT were divided into three groups.Group Ⅰ , 26 patients,experienced at least one prolonged seizure after MECT;group Ⅱ,41 selected patients, had not prolonged seizures at all during a course of MECT treatments and group Ⅲ, 31 patients, received simulated ECT.Biochemical markers of myocardial injury, including phosphocreatine kinase (CK), MR isoenzyme of phosphocreatine kinase (CK-MB), lactate dehydrogenase ( LDH ), α-hydroxybutyrate dehydrogenase ( α-HBDH ) and cardiac troponin (cTnT) ,were measured immediately, 3 hours later and on the following day after the first prolonged seizure for group Ⅰ ,the same time points as group Ⅰ after the first treatment of MECT for group Ⅱ , immediately after simulated ECT for group Ⅲ.These indexes were compared between the patients of three groups.Results The positive rate ofcTnT was 30.8%(8/26) and 17.1% (7/41)in group Ⅰ and Ⅱ respectively, but no difference was found(P＞0.05 ).CK measured immediately after MECT in patients of group Ⅰ was significantly higher than that of group Ⅲ(P ＜ 0.05 ).CK-MB (immediately), LDH ( immediately and 3 hours later) and α-HBDH ( immediately, 3 hours later and on the following day) in patients of group Ⅰ were significantly higher than those of group Ⅱ and Ⅲ measured after MECT or simulated ECT(P＜0.05 ).Conclusion More attention should be paid that absolute or relative hypoxemia may lead to minor myocardial injury.

Objective To investigate the feasibility and safety*with the low dose fentanyl for valve replacement fast track cardiac anesthesia. Methods 40 cases with cardiac valve replacement were divided into two groups,group Ⅰ :20 cases with fast track anesthesia,group Ⅱ :20 cases with large dose fentanyl anesthesia. The blood presure, HR, SpO2, CVP,Temperature, airway pressure were observed at different time points. The postoperative extubation time,ICU stay,hospital stay,postoperative pulmonary complications were recorded. Results The fentanyl(μg/kg) of group Ⅰ (23. 25 ± 1.32) was less than that of group Ⅱ ( 35.75 ± 6. 84) ( P < 0. 05 ); Extubation time (hours), ICU stay ( hours),length of stay (days) were ( 7.92 ± 3. 16), (25. 12 ± 7.50), ( 28.50 ± 8. 94 ) in group Ⅰ , and that were (13.70±5.63) ,(37.53 ±13. 19) ,(38.00 ± 12. 90) in group Ⅱ. The group Ⅰ were shorter than the group Ⅱ ,P<0. 05; There were four cases of lung infection in group Ⅱ, no one in group Ⅰ ( P < 0. 05 ); There were significant differences between the two groups. There were no significant differences in the remaining observations. Conclusion The low dose fentanyl anesthesia for fast track anesthesia in heart valve replacement surgery was reliable and safe;It could help to reduce postoperative extubation time, ICU stay time and hospital stay time and reduce postoperative pulmonary complications and hospital costs.

BACKGROUND:Smal intestinal submucosa is characterized as antimicrobial activity, good biocompatibility, bio-mechanical properties, and rapid degradation in vivo, similar to the extracellular matrix of meniscal
fibrochondrocytes.
OBJECTIVE:To observe whether there exists a good histocompatibility between smal intestinal submucosa and synovial mesenchymal stem cells.
METHODS:Smal intestinal submucosa was treated with physical and chemical treatment. And hematoxylin-eosin staining and scanning electron microscopy observation were performed. Then, smal intestinal submucosa extracts were prepared for the fol owing experiments. (1) Pyrogenic test:smal intestinal submucosa extracts were injected into the ear vein of New Zealand white rabbits. (2) Skin sensitization test:smal intestinal submucosa extracts, paraformaldehyde solution and normal saline were respectively injected intradermal y into New Zealand white rabbits. (3) General toxicity test:smal intestinal submucosa extracts and normal saline were respectively injected into the ear vein of New Zealand white rabbits. Smal intestinal submucosa was co-cultured with osteogenic rabbit synovial mesenchymal stem cells, and smal intestinal submucosa cultured alone served as control. RESULTS AND CONCLUSION:There were some intestinal mucosal epithelial cells, fat cells and other cells adhered onto the surface of smal intestinal submucosa after physical treatment. While, the amount of residual cells decreased sharply after chemical treatment. But the main structure and the component had not been changed. The surface of smal intestinal submucosa was smooth and no cells remained, and there was a three-dimension network spatial structure. The porosity was 80%. Smal intestinal submucosa is a non-toxic, nonirritating, non-immunogenic biomaterial with very good biocompatibility, which has a good histocompatibility with rabbit synovial mesenchymal stem cells.
