At present,thyroid surgery is widely carried out during clinical practice.Because of preoperative or intraoperative misdiagnosis,nonstandard scope of operation,tumor recurrence and other factors,resulting in some cases needed to treat again.Due to the previous surgical scar adhesion and disordering of anatomical structure,the risk of injury of recurrent laryngeal nerve(RLN)increased manyfold.Intraoperative neuromointoring(IONM)is a technology for monitoring the functional integrity of the nervous system in state of dangerous by neural electrophysiological means.Better than the naked eye to identify and prompt the recurrent laryngeal nerve injury,to find the site of injury,IONM can significantly reduce the chance of transient RLN injury during thyroid reoperation as a sharp weapon to protect RLN.

Objective To compare the effect of hepatic oval cells and bone marrow mesenchymal stem cells to treat liver fibrosis in mice. Methods The C57BL/6 mice were fed with 3,5-diethoxycarbonyl-1, 4-dihydro-collidine (DDC) in a standard food at a concentra-tion of 0.1% to activate the oval cells proliferation, then the nonparenchymal cells were separated by in situ perfusion and density gradient centrifugation, and finally Sca-1 antibody was used in conjunction with magnetic activated cell sorting (MACS) to separate the Sca-1 +cells. Other mice were injected subcutaneously with CCl4 to establish experimental liver fibrosis model. Finally, the fibrosis mice were trans-planted with HOC or MSC or saline by spleen injection according to the group they belonged to. Four weeks later, the liver function index, the hydroxyproline and the histopathological change among the groups were used to evaluate the effect of the treatment. Result The liver function index was improved after transplantation. HOC and MSE treatment could reduce both the hydroxyproline level and alleviate the fibro-sis, but HOC seems more effective in the group with continuing CCl4 injection(P < 0.05). When stopping injecting CCl4, the change of fi-brosis was not visible(P >0.05). Conclusion Both hepatic oval cells and bone marrow mesenchymal stem cells can improve the liver function, and alleviate the fibrosis level by transpleen transplantation, but hepatic oval cells were more effective.

especially in the group of ceasing CCl4 injection. Conclusion After transplanted into the liver by spleen injection, hepatic oval cells could plant in the portal area, which improve liver function and alleviate the cirrhosis level.

Objective To compare the effects of small dose remifentanil and fentanyl on hemodynamic responses to orotracheal intubation in children.Methods Ninety ASAⅠorⅡchildren (57 males, 33 females) aged 3-9 yrs weighing 17-34 kg scheduled for elective plastic surgery under general anesthesia were randomly allocated to one of 3 groups (n = 30 each): groupⅠcontrol (C); groupⅡfentanyl (F) and groupⅢremifentanil (R) . The children were premedicated with intramuscular scopolamine 0.01 mg?kg-1(the maximum dose 0.3 mg) and midazolam 0.1 mg?kg-1.Anesthesia was induced with propofol 2.5 mg?kg-1 and vecuronium 0.1 mg?kg-1. In group F fentanyl 2?g?kg-1 was injectedⅣ5 min before intubation while in group R remifentanil 1?g?kg-1 was injectedⅣover 30 seconds immediately after vecuronium. Tracheal intubation was performed at 2 min after vecuronium injection. Noninvasive BP and HR were recorded and RPP (SBP?HR) was calculated before (baseline) and immediately after induction (T1),during intubation (T2) and at 1,2,3,4, 5 min after intubation.Results BP was significantly decreased after induction of anesthesia (T1) as compared to the baseline values in all 3 groups (P

To study the changes in median frequency (MF) from a surface electromyogram of skeletal muscles and functional assessment of chronic illness therapy (FACIT) figure scale scores for patients with chronic fatigue syndrome (CFS) before and after Tuina treatment.

Objective:To study the tuina effect on sleep disorder and emotional problems of chronic fatigue syndrome (CFS) cases.Method:Thirty CFS cases were treated in the treatment group,by applying one-thumb pushing,rolling and pressing-kneading manipulations along the Governor Vessel,Bladder and Yangming Meridians.The intended major points include Fengfu (GV 16),Yaoyangguan (GV 3),Xinshu (BL 15),Pishu (BL 20),Ganshu (BL 18),Hegu (LI 4) and Taixi (KI 3).The treatment was done once every other day;10 times constitute a course of treatment.Another 30 healthy cases were selected in the control group,without any intervention.The sleep quality and mental state in the two groups were evaluated by PSQI,HAMA and HAMD.In addition,the pre-treatment and post-treatment score changes were observed.Results:Before treatment,the total score of PSQI,sleep quality,time of falling asleep,sleep efficiency,sleep disorder,daytime functional impairment,and scores of HAMD and HAMA in treatment group were all substantially higher than the control group (P＜0.01).After 10 tuina treatments,the total score of PSQI,time of falling asleep,sleep disorder and daytime functional impairment as well as scores of HAMD and HAMA in treatment group were significantly changed,compared with before treatment,P＜0.05.Conclusion:Those with CFS may present with sleep disorder and mental or psychological abnormality,tuina can improve their sleep quality and adjust their mental conditions.

Objective To explore the experiment condition and method for the application of in vitro in vasive Transwell chamber and to observe muscarinicreceptor stimulant and muscarinicreceptor antagonist's influence to cholangiocarcinoma's invasiveness.Methods Two hundred microliter cell suspension of various concentrations(0.5×105/mL,1.0×105/mL,1.5×105/mL and 2.0×105/mL)was added into the upper chamber of the Transwell chamber,and the cells were allowed to penetrate the matrigel for 12,18,24and 48 hours respectively.The numbers was gotten as the invasive cells on the under surface of the membrane.After optimal cell concentration and time were gotten,pilocarpine of various concentrations(0 mmol/L,0.1 mmol/L,0.3 mmol/L and 0.5 mmoL/L)was added into the upper chamber of the Transwell chamber,then the cells on the matrigel were stained and counted.So did the cells when atropine of various concentrations(0.01 mmol/L,0.01 mmol/L,0.05 mmoVL and 0.1 mmol/L)were added into the upper chamher of the Transwell chamber in according to pilocarpine of various concentrations(0 mmol/L,0.3 mmol/L,0.3 mmol/L and 0.3mmol/L).Results With the increase of the time and cell concentrations，the cells couts that penetrated the matrigel increased，while the increase tended to he stable when the culture time exceeded 36 hous and the cell concentration Was over 1.0×105/mL.By adding pilocarpine,there were significant differences between the control and experimental groups(P＜0.05)，but there were no significant differences in experimental groups with various concentrations.There were no significant differences in blank group and experimental groups with atropine added(P＞0.05).When added pilocarpine and atropine,there were significant differences between blank and experimental groups(P＜0.05)，but there were no significant differences in experimental groups with various concentrations.Conclusions Thirty-six hours as invasive time,and one cell concentration 1.0 × 105/mL were optimal to test invasion abilities of cholangiocarcingma cells to different medicines or reagents.There is the possibility that museariniereceptor exists in cholangiocarcinoma cells，and may play an important role in cholangiocarcinoma's invasiveness and metastasis.

Objective To investigate the effects of adiponectin (APN) on proliferation,migration and tube formation of RF/6A cells,and explore the effects of APN on choroidal and retinal angiogenesis.Methods Well cultured RF/6A cells were randomly divided into the control group and three groups with different concentrations of recombinant adiponectin (5 pg · mL-1,50 pg · mL-1,500 pg · mL-1) for 1 hour.After 24 hours,cell proliferation,migration and tube formation were detected by MTT assay,wound scratch assay and seeding cells in matrigel,respectively.Results The cell proliferation in all APN groups was weaker than that of control group (P ＜ 0.05),the cell migration area (pixels) of all APN groups was significantly smaller than that of the control group (P ＜ 0.05),and the number of tube formation of all APN groups was significantly less than the control group (P ＜ 0.05).Cell proliferation,migration and tube formation decreased along with the increase of APN concentration.Conclusion APN can obviously inhibit the angiogenesis process of RF/6A cells.This inhibitive effect indicates the protective role of APN in choroidal and retinal angiogenesis.
