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.

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

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 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.

ObjectiveTo observe the curative effect of Xiangshaliujunzi decoction on critically ill patients with gastrointestinal dysfunction accompanied by spleen deficiency syndrome of traditional Chinese medicine (TCM) and its influence on tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6).Methods Forty-eight critically ill patients admitted to Department of Emergency Intensive Care Unit (EICU) in Zhejiang Provincal Hospital of Traditional Chinese Medicine Xiasha Campus from February to December 2015 were enrolled, and they were randomly divided into observation group (26 cases) and control group (22 cases) by random number table method. The patients in both groups were given routine emergency western therapy, and in the observation group, additionally, Xiangshaliujunzi decoction (ingredients: codonopsis pilosula 20 g, atractylodes macrocephala koidz 12 g, poria cocos 12 g, radix glycyrrhizae preparata 4 g, rhizoma pinelliae preparatum 6 g, pericarpium citri reticulatae 5 g, fructus amomi villosi 5 g, radix aucklandiae 4 g, rhizoma zingiberis recens 3 pieces) 80 mL was prepared and divided into two parts for nasal feeding, once 40 mL, twice a day, while the patients in the control group received the nasal feeding with the same amount of warm boiled water. Before treatment and 3 days and 5 days after treatment, the gastrointestinal function scores were assessed, and the changes of the levels of plasma TNF-α, IL-6 were recorded.Results There were no statistical significant differences in gastrointestinal function scores, the levels of TNF-α and IL-6 between the two groups before treatment and 3 days after treatment (allP ﹥ 0.05). But 5 days after the treatment, the gastrointestinal function scores, the levels of TNF-α and IL-6 were obviously decreased in two groups, and the degree of decrease in observation group was more significant [gastrointestinal function score: 0.92±0.85 vs. 2.27±0.77, TNF-α (ng/L): 17.7±2.4 vs. 25.0±4.2, IL-6 (ng/L): 16.9±2.4 vs. 25.0±3.4, allP < 0.01].Conclusion Xiangshaliujunzi decoction has therapeutic effect on critically ill patients with gastrointestinal dysfunction and accompanied by spleen deficiency in TCM, the mechanism may be related to decreasing the levels of TNF-α and IL-6, thereby depressing the inflammation.

AIM: To observe the curative effect of titanium wiring in treatment of the fractures of Neer Ⅱ type distal clavicle and dislocation of Tossy Ⅲ type acromioclavicular joint. METHODS: From March 2004 to December 2006, 37 cases with Neer Ⅱ type distal clavicle fractures or Tossy Ⅲ type acromioclavicular joint dislocation were treated with titanium wiring in Changzheng Hospital, Second Military Medical University of Chinese PLA. Titanium wiring (produced by Sofamor-Danek Company in USA) had good histocompatibility, intensity of tension and flexibility. The broken coracoclavicular ligament was repaired directly by titanium wiring in all cases. The outcomes were evaluated according to Herscovici's criteria. RESULTS: All the cases were followed up for 6 to 24 months. All the dislocated acromioclavicular joints returned to normal 2 weeks after operation. Excellent and good rate of shoulder function was 100% according to Herscovici standard. X-ray imaging showed all clavicle fractures united, acromioclavicular joint had no redislocation or titanium wiring breaking. The incisions of all cases had no obvious swelling and exudation. CONCLUSION: When Neer Ⅱ type distal clavicular fracture and Tossy Ⅲ type acromioclavicular joint dislocation are treated with titanium wiring, the acromioclavicular joint can exercise earlier and recover quickly.
