Objective Video-assisted thoracoscopic surgery is widely used in clinical practice,due to the characteristics of minimal invasion,quick recovery,low incidence of postoperative chest pain and the same effect of lobectomy as thoracotomy.However,the surgical itself has a certain degree of difficulty,and due to the effect of lymph node,intraoperative blood loss,pleural adhesions,conversion to thoracotomy surgery is needed in some cases. Understanding the risk factors of conversion to thoracotomy can help thoracic surgeons figure out the right time to operate the surgery.

Objective To summarize the experience of pituitary adenoma resection by single-nostril transsphenoidal approach and analyze the indications,intraoperative and postoperative common problems in order to improve the technique and quality of life.Methods Summarize the clinical data of 611 pituitary adenoma resections by single-nostril transsphenoidal approach from January 2005 to June 2010 retrospectively,reanalyze the choice of operative indications,analyze the bleeding during the operation and sums up the relevant pro cessing suggestions,and summarize the reasons and countermeasures of postoperative visual impairment.Results The tumors were totally removed in 538 cases,sub-resections in 59 cases,sub-totally removed in 14 cases,and no deaths.Eleven cases were poor gasification or concha sphenoid sinus in 11 totally removed patients.The bleeding came from diploe,emissarium,mucosa of sphenoid sinus,diploe,epidural space,dura matter of the sella turcica region,intercavernous sinuses,tumor or the tumor bed.The bleeding was controlled effectively with different approaches.There were 3 patients who underwent visual impairment,and the impairment was improved after treatment.Conclusion Following the correct operation principle,we can improve the rate of total resection; the single-nostril transsphenoidal approach is also suitable for the poor gasification; The prognosis can improve after deal with the intraoperative and postoperative common problems.

Objective To investigate the characteristics of cognitive changes in type 2 diabetes mellitus pa-tients complicated with stroke. Methods One hundred and one stroke patients were recruited and allocated to thetype 2 diabetes mellitus group (34 patients) and sixty-seven patients in the control group (67 patients) according tobeing with or without type 2 diabetes mellitus. All the patients were evaluated, after 3 weeks, 6 months and 12months of onset of stroke, with regard to their cognitive functions by using the Mini-mental State Examination(MMSE) and Montreal Cognitive Assessment (MOCA). Results Average scores obtained in MMSE and MOCAtests were significantly lower at 3 weeks and 6 months after onset in the type 2 diabetes mellitus group when comparingwith control group. In the type 2 diabetes mellitus group, no significant difference was observed between 3 weeks and6 months after onset of stroke with regard to scores of MMSE and MOCA ( P > 0.05 ), however, the score at 6 monthswas significantly lower than that at 12 months after onset (P <0.05). On the other hand, scores of MMSE (P >0.05 ) and MOCA (P > 0.05 ) in the control group were not any statistically different among various time points ofobservation. Conclusion Type 2 diabetes mellitus will aggravate cognitive dysfunctions of stroke patients, whichstarted to recover in 6 months of onset of the stroke.

Objective: To establish the method of fingerprint analysis on volatile oil of Pogostemon cablin (Blanco) Benth. cultivated in Shipai country by GC MS, and to study the main characteristic components. Methods: The main components of the volatile oil of Pogostemon cablin (Blanco) Benth. from different colletion time in Shipai country were determined by GC MS, and compared with the volatile oil of “Gaoyao huoxiang” and “Hainan huoxiang” cultivated in the same GAP plots. Results: RSD of precision and reproducibility and stability is in the range of 5%, and the main components of the volatile oil of “Shipai huoxiang” from different collection time are nearly similar, and the content of Pogostone increases along with cultivation time, and the content of Pogostone and Patchoulic alcohol are significantly differences compared with the “Gaoyao huoxiang” and “Hainan huoxiang”. Conclusion: The method is reliable, accurate and can be used for quality control of volatile oil of Pogostemon cablin (Blanco) Benth.

4 ng/ml and/or with prostate nodule found on DRE or TRUS . Methods 197 patients suspected of prostate carcinoma underwent ultrasound guided sextant biopsy and 2～4 more cores in the nodule. Four patients whose initial biopsy was negative but subsequent PSA levels were continuously abnormal underwent repeated biopsies. Results Of the 107 cases with prostate nodules,in 34(31.8%) of them prostate cancer was detected,while in 90 cases without a prostate nodule, only 11(12.2%) were positive. Stratified analysis on PSA found that the higher the PSA, the higher the positive biopsy rate of prostate carcinoma. In the 4 cases with repeated biopsies, 1 prostate cancer was detected. Conclusions For patients with prostate nodule and/or PSA over 4 ng/ml,systematic biopsy should be taken, with 2 or more cores toward the nodule.In the patients with continuous high PSA levels,if the first biopsy is negative, rebiopsy should be taken.

Objective To evaluate the mental health status of train conductors in order to ensure the safety of railway transportation.Methods The mental health status of train conductors was measured using the Chinese version of the SIMH mental health self-evaluating table(SCL-90).Results Compared with the national norm,there was a significant higher mean in nine factors of mental health for the train conductors(t test,P

Objective To develop a new method, the bone marrow stromal cells (BMSCs)-mediated tissue engineering technique combined with mosaicplasty, for repair of osteochondral defects and integration of gaps. Methods BMSCs from 12 Chinese goats were cultured and proliferated in vitro. Prior to the BMSCs harvest, osteochondral defects, 5 mm in diameter and 3 mm in depth, were created in the femoral medial condyles of both the goat's hind limbs. When the mosaicplasty (osteochondral autograft transplantation) was performed, the BMSCs, which had been harvested and compounded with hyaluronic acid, were injected into the gaps between the osteochondral autografts in the left hind limb. The right hind limb which only received osteochondral autograft transplantation without BMSCs served as a control. At four, eight and 16 weeks post-operatively, samples of the repaired defects were harvested and assessed by histological evaluation, immunohistochemical analysis and glycosaminoglycan (GAG) quantification. In both groups 16 weeks post-operatively, the GAG quantification was analyzed by one-way ANOVA and least significant difference (LSD) method. Results At all the time points, the cartilage autografts in both groups survived as hyaline cartilage and presented no significant difference from the surrounding native cartilage. In the group filled with BMSCs compound, the gaps were replaced by regenerated hyaline cartilage and disappeared; however, in the control group, the osteochondral autografts were still distinct from the surrounding normal cartilage, though the gaps were replaced by fibrous tissue or fibrous cartilage. Immunohistochemical analysis of typeⅡcollagen showed positive staining in the matrix of transplanted and regenerated cartilage. The Alcian blue method also confirmed a significantly less GAG content in the regenerated tissue in gaps in the control group than in the treatment group and in the normal cartilage. Conclusion Since tissue engineering combined with mosaicplasty can promote gap integration and cartilage healing, the method can be an ideal way for osteochondral defect repair.
