Objective:To observe the dexmedetomidine by nasal drip on perioperative spinal surgery patients sedation and the effect of hemodynamic changes.Methods:90 ASA grade Ⅰ ～ Ⅲ,years 18 to 65,and in general anesthesia spinal surgery,and postoperative patients have to extube the endotracheal,were randomly divided into three groups:control group (group C),the dexmedetomidine 0.1 μg/kggroup (D1) and dexmedetomidine 1.5 μg/kggroup (D2),(n=30).Record into the OR (T0),before the induction (T1),1 min before intubation (T2),1 min after intubation (T3),start surgy (T4),began to stop general anesthetics (T5),1 min before extubation (T6),3 min after extubation (T7),and into the PACU (T8).The patient's heart rate (HR),mean arterial pressure (MAP),oxygen saturation (SPO2),finish operation from the general anesthetics toextube the endotracheal tube,stay time,patients in the postoperative recovery room Ramsay sedation scores.Results:Three groups of patients when T0 HR,MAP,SPO2,Ramsay sedation scores had no statistical difference (P≥ 0.05);Compared with group C,D1 and D2 group significantly lower each time point of HR,MAP,Ramsay sedation scores increase (P≤ 0.05),SPO2 no significant change (P≥ 0.05);Each time point compared with group D1,D2 group HR,MAP,significantly decreased,Ramsay sedation scores increase (P≤ 0.05),SPO2 no significant change (P≥ 0.05);D1 group HR,MAP,SPO2 at each time point,Ramsay sedation scores have no obvious difference (P≥ 0.05);D2 group HR,MAP,SPO2,Ramsay sedation scores significantly difference (P≥ 0.05).Group C T3,T4,T5,T6,T7 has each time point,T8 HR,MAP,up from T1,T2,Ramsay sedation scores were significantly improved (P≤ 0.05),SPO2 no significant change (P≥ 0.05).Conclusions:40 min before anesthesia induction dexmedetomidine by nasal drip can effectively inhibit intubation and extubation reaction,make the hemodynamic changes is more stable,and significantly reduce the incidence of patients with postoperative agitation.

Objective To observe the effect of acupuncture at neck Jiaji acupoints combined with moxibustion to cervical vertigo.MethodsIn Wuhan Chinese and Western Union Hospital from August 2015 to November 2016, 80 patients with cervical vertigo were randomly divided into two groups, the treatment group was treated by needling cervical Jiaji points, at the same time with moxibustion on neck Jiaji acupoints, the control group was given drug treatment.ResultsThe total effective rate in the treatment group was 95%, but the control group total effectiveness was 72.5%, the effect of the two groups had significant difference(P<0.05).ConclusionAcupuncture at Neck Jiaji points combined with moxibustion treatment had the functions of relieving rigidity of muscles and activating collaterals,dispelling cold and dredging channel blockage, relieveing local muscle spasm,improveing blood circulationand improve the function of the blood supply to the brain to vertigo.

Objective To evaluate the role of nuclear factor kappa B (NF-κB) in sevofluraneinduced release of inflammatory factors in mouse microglias.Methods Microglial cells obtained from newborn C57BL/6 mice (aged 2-3 days) were seeded in 24-well plates (density 1 × 105 cells/ml, 1 ml/well) , a total of 80 wells.The cells were randomly divided into 4 groups using a random number table (n =20 each) : control group (group C);sevoflurane group (group S);NF-κB selective inhibitor pyrrolidine dithiocarbamate (PDTC) group (group P);PDTC + sevoflurane group (group P +S).In S and P+S groups, 4.1％ sevoflurane was inhaled for 6 h.In P+S group, 10 μmol/L PDTC was added at 1 h before sevoflurane inhalation.At 6 h of incubation with sevoflurane, NF-κB activity and expression and levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were determined.Results Compared with group C, the NF-κB activity and levels of IL-6 and TNF-α were significantly increased in group S, and no significant change in the above parameters was found in the other two groups.Compared with group S, the NF-κB activity and levels of IL-6 and TNF-α were significantly decreased in group P+S.There was no significant difference in NF-κB expression between the four groups.Conclusion NF-κB mediates sevoflurane-induced release of inflammatory factors in mouse microglias.

ObjectiveTo explore the clinical therapeutic effect and safety of treating the vertebral artery type cervical spondylosis with rotational manipulation.Methods180 patients with vertebral artery type cervical spondylosis were treated by rotational manipulation.ResultsBy follow-up, 89 patients were evaluated as excellent, 73 as good and 18 as fair. The total rate of excellent and good results was 81%.ConclusionRotational manipulation is an effective method. The correct diagnosis and indication are keys to take good treatment results and safety.

Objective: To investigate the killing activity of cytokine-induced killer (CIK) cells after incubation with autologous tumor cell lysate-pulsed dendritic cells (Ag-DC) and to evaluate the immune functions of patients, the clinical efficacy and side effect of Ag-DC in combination with CIK on hepatocellular carcinoma. Methods: Peripheral blood mononuclear cells were isolated from 24 patients with hepatocellular carcinoma, and cultured with granulocyte-macrophage colony-stimulating factor and interleukin-4 to produce dendritic cells (DCs). The DCs were pulsed with autologous tumor cell lysate. T lymphocytes from PBMC were cultured with interferon-Y (IFN-γ), IL-2, CD3-moAb, and IL-1α to prepare CIK. The killing effect of CIK on SMMC-7721 was investigated after CIK was incubated with Ag-DC. After immunotherapy with Ag-DC and CIK, immunolog-ic and clinical responses of the 24 patients were evaluated. Results: The killing effect of CIK was remarkably improved after CIK was incubated with Ag-DC. The immunotherapy with DC and CIK alleviated symptoms and improved the immune functions of the patients. Except for transient fever and chill, no remarkable adverse events were observed. Conclusion: Ag-DC in combination with CIK shows short-term efficacy on hepatocellular carcinoma through inducing specific anti-tumor immunity and can be an effective adjuvant therapy for hepatocellular carcinoma.

Objective By using quantum dots-based double-color imaging method to simultaneously label human epidermal growth factor 2 (HER2) on breast cancer cell membrane and the type Ⅳ collagen in the extracellular matrix.To monitor the degree of malignancy of breast cancer and the invasive and metastatic potential.Methods The co-expressions of HER2 and the type Ⅳ collagen in breast cancer of 54 cases were detected and quantified by quantum dots-based double-labeling immunofluorescent histochemistry,and its correlation with clinical pathology parameters and prognosis were analyzed.Results With the increasing HER2 expression level,a progressive decrease in collagen Ⅳ around the cancer nest,the expression of HER2 and the type Ⅳ collagen value was negatively correlated (r =-0.980,P ＜ 0.05) ; the expression of HER2 and collagen Ⅳ was associated with lymph note metastasis,pathological stage (TNM) and disease-free survival(P ＜ 0.05).The expression of HER2 and the type Ⅳ collagen between different age groups,menopause and estrogen receptor (ER) and progesterone receptor (PR) were not significantly different (P ＞ 0.05).Conclusions Quantum dots-based double-color imaging method provides direct observable evidence to support the degradation of HER2 and the type Ⅳ collagen expression,which may help in determining the degree of malignancy and evaluating prognosis.

Withanolide A is a biologically active secondary metabolite occuring in roots and leaves of Withania somnifera. In the present study, adventitious roots from leaf explants of W. somnifera were induced for the production of withanolide-A by Agrobacterium tumefaciens strain C58C1 to obtain hair roots. Hair roots induction rate reached 30%. The withanolide A was determined by HPLC in different hair roots lines and different parts of W. somnifera. The average content of withanolide A in all hair roots lines were 1.96 times as high as that in wild-plant, the concentration of withanolide A in hair roots (1.783 mg x g(-1) dry weight) were 1.51 times as high as the roots of wild W. somnifera (1.180 mg x g(-1) dry weight), respectively. It is possible to obtain withanolide A from hair roots culture of W. somnifera.
