Objective To evaluate the adhesion, proliferation and osteogenic differentiation of rabbits' mesenchymal stem cells (MSCs) cultured in demineralized bone matrix coated with OB-Cadherin. Method The second generation of MSC s were seeded onto the OB-Cadherin cover over allogenic frozen-dried demineralized bone matrix(FDBM) and the FDBM without OB-Cadhefin as control, and then both were cultured separably in vitro. The densities of seeded cells, the adhesion rate were measured, and their ALP activity was assayed in order to take it as an index of cell adhesion, proliferation and osteogenic differentiation. The growth and adhension of MSCs on the FDBM was observed and evaluated microscopically and electronic scanning microscopically. Data were ex-pressed as means and standard deviation (x±s), and were analyzed with SPSS 12.0. Independent-Sanples T-test and Paired t test was used, and P<0.05 indicated statistically significant. Results There was no significant dif-ference in cell proliferation between modified FDBM and unmodified FDBM cultured fot 7, 14, 21 d. ays. After culture for 20 hours, the adhesion rate in the control group was (35.56±1.75)%, the densities of seeded cells were less than 2.7×104. The adhesion rate of cells in the modified group was consistent at 80%, whereas the densities of seeded cells were as high as 5.0×105 compared with control group (P<0.01). After cultured for 20 hours, the efficiency of cell adhesion in the modified FDBM was higher than that in the unmodified FDBM. After cultured for 7 days, the cultured MSC on modified FDBM expressed higher AIP activity, and after cultured for 14 days, the ALP activity on modified FDBM was much higher than that on unmodified FDBM (p<0.01). After cultured for 14 days, osteocalcin immunohistochemical positive rate of modified group was (71±11)%, while that of the control group was(49±8)% with significant difference Conclusion OB-Cadherin enhances cell adhesion to FDBM and promotes MSC to differentiate to osteoblast, but no obvious effects d OB-Cadherin on cell proliferation were observed.

The levels of IFN-? and IL-2 in the salivary juice of the three groups were determined and compared before and after the treatments. Results The levels of IFN-? and IL-2 in the group A and B before the treatments were higher than the normal control group (P

Chronic insomnia is a severe disease that seriously influence the human health,and about 10%-15% of the adults suffer from it.No definite conclusion has been made about its etiology up to now,possibly associated with heredity,hormone secretion and living habits.Insomnia not only decreases the patients' quality of life,but also adds burden to society,families and individuals.The diagnosis of chronic insomnia should be based on the patients' sleep history,medication history,psychiatric history and necessary examinations.International diagnosis criteria should be combined if possible.Presently the treatments for chronic insomnia mainly include the OTC medicine,prescription drugs,self-medication with alcoholic beverage,cognitive behavior therapy,melatonin and some traditional herbal therapies.Limited information is available presently about insomnia and a large amount of laboratory and clinical research need to be done to further understand and solve this public problem.

Objective To report the microsurgical separation of the protruded cerebral tissue in the case of complex craniopagus twins and evaluate the role of the neuronavigation system in this operation Methods After the multiple bone flap were made,register again and then separate the cerebral tissue along the arachnoid plane under the guiding of the neuronavigation system(SNN) until the straight sinus was exposed Results The protruded cerebral hemisphere and cerebellar hemisphere of the twins were successfully separated Unfortunately,part of the occipital lobe of twin B(right) had to be removed because of the brain swelling Conclusion In the case of complicated craniopagus,the neuronavigation system is valuable in positioning the deep common sinus To separate the cerebral tissue along the arachnoid plane under surgical microscope can reduce the cerebral injury

Objective To investigate the influence of the radical resection and the optic canal unroofing on the postoperative vision in the patients with tuberculm region meningeal tumors.Matheods A retrospective analysis was made in 44 patients with tuberculm region meningeal tumors,from January 2010 to October 2012.The clinical data including the Simpson grades,adhesion between tumor and the surrounding structures,optic canal decompression,and postoperative vision were studied,and followed-up.Results In all 44 cases,there were 31 patients with Simpson grade Ⅰ resection,their postoperative vision of 17 patients were improved,eleven unchanged,and 3 worse.Out of them,tumors showed more adhesive in 9 cases,unroofed the optic canal in 17 cases.There were 13 cases in the other group including 8 cases with Simpson grade Ⅱ and 5 cases with Simpson grade Ⅲ,their postoperative vision of 8 patients were improved,four unchanged,and 1 worse.Out of them,tumors showed more adhesive to the surroundings in 10 cases,unroofed the optic canal in 3 cases.There were no different postoperative vision among the Simpson grades by the Chi-Square test (P ＞ 0.05).The less adhesive of the meningeal tumors,the better resection grade would be (P ＜ 0.05).And unroofed the optic canal group showed better postoperative vision than the not unroofed ones (P ＜ 0.05).Conclusion In the tuberculum region meningeal tumors,the Simpson resection grade was related to adhesion between the meningeal tumors and the surroundings,not to postoperative vision.The optic canal decompression can improve their visual outcome in some cases.

Objective To explore the influencing factor of duration of untreated psychosis(DUP) and the relationship between duration of untreated psychosis and treatment outcome in epidemiological first-episode schizophrenia. Methods 912 medical records of the first episode schizophrenia patients were recruited in the study for epidemiological survey . The general medical data, clinical diagnosis, and treatment outcome were collected. DUP was determined refer to symptom onset for schizophrenia (SOS) scale. Patients were divided into short DUP and long DUP groups according to the median values of DUP values. Results Between short DUP and long DUP groups, the difference in marriage was significant ( P < 0. 05). The unmarried patients in the short DUP group (63.7% ) was higher than the long DUP group (52.6% ), the variance was significant (λ2 =5.990, P<0.05). The divorce in the short DUP group (0.6% ) was lower than the long DUP group (4.4% ) , the variance was significant (λ2 =5.079, P<0.01).The simple schizophrenia in the short DUP group (1.5%) was lower than the long DUP group (4. 1% ) , the variance was significant (λ2 =5.868, P<0.05). The treatment outcomes between the two groups had a significant variance ( λ2 =36.093, P < 0.01) , and the Ridit analysis of treatment outcomes between the two groups showed significant difference ( u = 5.183, P<0.01). The marriage,age of onset and clinical diagnosis were significantly correlated with DUP in multiple factor Logistic regression analysis. Conclusion The marriage,age of onset and clinical diagnosis are significantly correlated with DUP in the first episode schizophrenia patients,the longer of DUP and the worse of treatment outcome.

Objective To investigate the clinical values of Gemstone Spectral Imaging coronary angiography with analysis of the relationship between plaque character and angina pectoris types.Methods Two hundred cases of hospitalized patients were collected from January 2015 to December 2016 in the Department of Cardiovascular Disease,Chenzhou City First People's Hospital,who were diagnosed as coronary heart disease.According to the clinical data,stable angina pectoris (SA) and unstable angina pectoris (UA),coronary CT scan was performed for each patient to evaluate the relationship between the nature of atherosclerotic plaques and the classification of angina pectoris.SPSS 19.0 software was used for statistical analysis.Results By analyzing the correlation between SA and UA,SA calcification plaque was accounted for 63.2％,soft plaque 17.4％,mixed plaque 19.4％;UA calcification plaque was accounted for 37.5％;Soft plaque was accounted for 42.3％;and mixed plate was accounted for 20.2％.The difference was statistically significant (P ＜ 0.05).In the SA group,all of the stenotic lesions were mainly calcified plaques.There was no significant difference in the degree of severe stenosis between the different plaques in the SA group (P ＞ 0.05).In UA group,soft plaques were the main lesion of mild and moderate stenosis of coronary artery,and calcified plaques were the main stenosis in severe stenosis.There were significant differences in the degree of coronary artery stenosis between different plaques in UA group (P ＜ O.05).Conclusions The 128-slice spiral CT can accurately evaluated the relationship between the nature of coronary plaque and the type of angina pectoris,which is of great value in the early warning and angina pectoris classification of high-risk patients with coronary heart disease.
