Objective To compare the effect and safety between lightwand and general-laryngo-scope application of trachea cannula in cervical spine fracture patients undergoing general anesthesia. Methods Forty cervical spine fracture patients with tracheal intubation anesthesia were selected,including twenty-eight males and twelve females,aged 18-65 years,ASA physical statusⅡor Ⅲ.These patients were randomly divided into two groups,twenty cases in each group.After anesthesia induction,group L was giv-en general laryngoscope intubation,whereas group C was taken lightwand guided tracheal intubation.The success case of intubation at first,intubation time,adverse reaction of intubation,changes of MAP and HR at intubation and 5 minutes after intubation were observed.Results Compared with group L,success rate of intubation at first was higher (90% vs.60%),intubation time was shorter [(31.3±11.1)s vs.(46.6 ±15.2)s]in group C (P <0.05).The changes of MAP and HR were more stable during intubation in group C compared with group L.Four cases of arrhythmia (20%)occurred in group C,while none in group L.Conclusion Compared with intubation by general laryngoscope,application of tracheal intubation led by lightwand in cervical fracture patients is more effective and safer.

AIM: To observe the effect of cannabinoid receptor (CB1R) agonist WIN55-212-2 on the expression of brain-derived neurotrophic factor (BDNF), c-Fos and protein kinase A beta-catalytic subunit (PKAC-β) in cerebrum cortex after intracerebral hemorrhage (ICH) in rats. METHODS: The intracerebral hemorrhage model of rat was made by the injection of collagenase Ⅶ, and WIN55-212-2 was intraperitoneally (ip) injected 30 min later. The rats were killed for sampling the brain tissues as specimens 24 h after ICH. The methods of immunohistochemical analysis and Western blotting were adopted to detect the expression of PKAC-β and BDNF. The mRNA expression of PKAC-β, c-Fos and BDNF was determined by RT-PCR. RESULTS: WIN55-212-2 obviously improved some nervous deficit symptoms and increased the expression of BDNF at mRNA and protein levels with upregulating the mRNA expression of c-Fos and downregulating the expression of PKA at mRNA and protein levels in the ipsilateral cerebral cortex. The proteins of PKAC-β, c-Fos and BDNF were expressed on the membrane or nucleus of the neuron or in the cytoplasm of glial cells, respectively. CONCLUSION: The expression of BDNF is induced not only by upregulation of c-Fos, but also by downregulation of PKA in WIN55-212-2 treated rats.

Objective To investigate the clinical curative effect of“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine for acute soft tissue sprain of the ankle.Method A total of 90 patients with acute soft tissue sprain of the ankle from emergency department of WangJing Hospital, CACMS were recruited from July 2013 to April 2014 and randomly divided into two groups with 45 patients in each. The patients in the treatment group were treated with the court manipulation, plaster and Chinese herbs washing, and those in the control group were only treated with cast immobilization. The clinical curative effect was evaluated using Baird-Jackson score system(excellent: 96-100; good: 91-95; fair: 81-90; poor: 0-80).Result At the second, third week after treatment, the excellent/good rates in the treatment group were significantly higher than those in the control group(at week 2: 73.3%vs. 44.4%;χ2=11.468,P<0.01; at week 3: 86.7%vs.60.0%;χ2=6.875,P<0.05). At week 2 and 3, Baird-Jackson scores in the treatment group(87.41±14.12, 93.16±9.51)and in the control group(76.32±11.41, 82.54±9.22)were significantly higher than those before treatment(treatment group: 72.11±12.61; control group: 71.67±13.12, allP<0.05); at week 3, Baird-Jackson score in the treatment group were significantly higher than that in the control group(P<0.05).Conclusion“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine can increase Baird-Jackson score and aid recovery of the ankle function in patients with acute soft tissue sprain of the ankle.

Objective To investigate the relationship between circulating tumor cells(CTCs) in peripher-al blood and the prognosis of pancreatic cancer patients. Method From Mar 2010 to Mar 2015, patients with pancreatic cancer in guangzhou first people′s hospital were enrolled in this study. Immunomagetic negative en-richhment together with immunofluorescence were used to identify CTCs. The clinical data of all patients were analyzed. Result No CTCs were found in peripheral blood of healthy control cases. The detection date of CTCs was 60.0%. The positive rate of CTCs was closely correlated with cell differentiation and the clinical stage. Con clusion CTCs count in old patients with pancreatic cancer can reflect the status of the patients and is help-ful for the diagnosis of micrometastasis , re-determination of the clinical stage and the guidance of patients′s treatment. CTCs count can predict the survival time of elderly patients with pancreatic cancer.

Aim To explore the effects of cannabinoid (WIN55,212-2) on mRNA and protein expressions of PKAC-β,c-fos and BDNF in cerebral cortex after intracerebral hemorrhage(ICH)in rats.Methods ICH model of rats were made by Ⅶ Collagenase,which were injected by the intraperitoneal route,thirty minutes after the operations.The rats were killed for brain tissue as specimens with 24 hours.The localizations of PKAC-β,c-fos and BDNF were assessed by immunohistochemistry;The expressions of PKAC-β,c-fos and BDNF mRNA were detected by RT-PCR;The expressions of PKAC-β and BDNF protein were revealed by Western blot.Results WIN55,212-2 increased not only the levels of BDNF mRNA and protein,but also c-fos mRNA in ipsilateral cerebral cortex.However,it decreased the levels of PKAC-β mRNA and protein.PKAC-β,c-fos,and BDNF proteins were expressed on membrane of neurons,nucleus of neurons or the cytoplasm of glial cells respectively.Conclusion WIN55,212-2 induces the expression of BDNF in the cerebral cortex,which provides a theoretical basis for the treatment of cerebrovascular disease.
