Objective To evaluate the effects of a single IV lidocaine bolus dose on the minimal alveolar concentration (MAC)of sevoflurane. Methods Patients (n=90), aged 25-65 years whose Anesthesiologists (ASA) classification wasⅠorⅡand underwent elective surgery on trunk under general anesthesia, were randomly divided into 3 groups with 30 cases in each group:high-dose lidocaine group (group H), low-dose lidocaine group (group L) and control group (group C). They were induced by sevoflurane inhalation, and ventilated by LMA (laryngeal mask airway). After a 15 minutes equilibration period with the above sevoflurane concentration , the medication to be studied (2%lidocaine 1.5 mg/kg for group H , 2%lidocaine 0.75 mg/kg for group L, 0.9%saline 5mL for group C) was administered for 3 minutes before the skin incision. The response to skin incision (movement versus no movement) was recorded in the first minute after skin incision. The MAC for sevoflu?rane was determined using the Dixon′s up and down method. Values of mean arterial pressure (MAP), heart rate (HR), and BIS were recorded at 1 minute and 5 minutes after being monitored (average values were noted as T0), immediately before the administration of medication (T1), immediately before the skin incision (T2) and 1 minute after the skin incision(T3). Results MAC in group H (2.00%± 0.17%) was lower than that in group C (2.22%± 0.18%) by approximately 0.22%,and which was lower than that of group L ( 2.21%± 0.14%) by approximately 0.21%(F=7.054,P<0.05). No significant differ?ence in the MAC of sevoflurane was noted between group L and group C. The values of HR, MAP and BIS all decreased at T 2 and increased at T3 in all 3 groups (all P<0.05). No significant difference in HR, MAP or BIS was observed between T0 and T1 in all three groups. The values of HR and BIS were lower in group H than those in group C and group L at T2 and T3. The values of MAP were lower in group L and group H than those in group C at T2 and T3. The value of MAP were lower in group H than that in group L at T2(all P<0.05). Conclusion A singleⅣ1.5 mg/kg lidocaine decreases MAC of sevoflurane, but the decreased amplitude (11%) does not reach expectation.

[Objective]To explore the professor Yu Tugen’s experience, in order to provide reference for clinical medication and the study of atopic der-matitis. [Methods] Treatment based on syndrome differentiation. First, through the analysis of etiology and pathogenesis and clinical manifestations of atopic dermatitis, it is divided into types, respectively analyze each type, discuss the experience in the treatment of various types; then give examples of the treat-ment experience of dampness heat syndromes, analysis of diagnosis and treatment system.[Result]Atopic dermatitis is divided into the types of damp-heat accumulation, spleen deficient aggregates the skin wet, wind formation from blood deficiency. After dialectical treatment, symptom is relieved.[Conclusion] This topic comprehensively summarizes the famous expert Yu Tugen ’s academic thought and clinical experience of atopic dermatitis of the types of damp-heat accumulation, provides a more complete treatment concept based on syndrome differentiation of TCM of atopic dermatitis, to relieve pain and improve the quality of life.

Objective To investigate the clinical characteristics and prognosis of acute myocardial infarction (AMI) combined with ventrical septal perforation (VSP).Methods Fifty-seven AMI + VSP patients were retrospectively analyzed their clinical characteristics and outcomes who were treated in the Fourth People' s Hospital of Shenyang and the First Hospital Affiliated to China Medical University from June 2000 to May 2014.Results Of all patients,43 (75.4％) VSP occurred anterior wall AMI,and 14 (24.6％) were not.Echocardiogram show the end diastolic diameter of left ventricle was (53.7 ± 9.5) mm,left ventricle ejection fraction was (48.5 ± 11.8)％,VSP diameter was (9.8 ±7.9) mm,and 37(64.9％) were with near apex.The level of cardiactroponin I,C-reactive protein,and N terminal of B type natriuretic peptide of patients were (16.7 ± 12.9) μg/L,(99.7 ± 31.40 mg/L,(3 051.2 ± 879.7) μg/L.Total mortality was 71.9％ (41/57) in 30 days and 78.9％ (45/57) in 1 year.The mortality of operation group was 73.9％ (17/23) in 30 days and 91.3％ (21/23) in 1 year.The mortality of consecutive therapy was 64.7％ (22/34) in 30 days and 76.5％ (26/34) in 1 year.Conclusion The mortality of AMI + VSP is higher and operation is the most effective therapeutic method.

[Objective] The aim of this study is to investigate the mechanism and curative effect of cataplasma of Artemisia Argyi by supercritical CO 2 fluid extraction to rat weight, foot swel ing, interleukin-1β, interleukin-17 and tumor necrosis factor-αin the adjuvant arthritis rat models;and afford theoreti-cal evidence for clinical work.[Methods]50 healthy male SD rats were randomly divided into 5 groups:Control group, Model group, Low-dose treatment group, Medium-dose treatment group, High-dose treatment group. Model and al treatment goups took CFA for model ing. After establishing animal models of AA rats, the first group and second group used cataplasm without active drug ingredients. Other groups were given treatment according to dif-ferent drug doses. Assess the joint swel ing degree at different times. Measure the arthritic index and rat weight in two weeks. After 21 days ,detect the cy-tokines level of IL-lβ,IL-17 and TNF-α from the rat's serum and examine the pathological changes of joint observed by HE . [Results]Cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction can significantly reduce rat foot swel ing of the ankle joint pathology ,reduce arthritis score and slow down the weight loss,meanwhile,effectively improve the general daily behavior of rats. The standard of IL-1β,IL-17,TNF-α in serum can be decreased by cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction. The pathological result showed: in the treatment group,the rats synovial hyperplasia the vesselwing reduced, the inflammatory cel infiltration was more decreased than the model group. [Conclusion]The result showed that the cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction had an obvious effect in treating RA. The mechanism was probably that it regulated the immune dis-order of RA.

To a certain extent, itemized government subsidies to public hospitals, primarily used for hospital infra-structure and large equipment investments, can alleviate the financial pressure of development expenditures and thus re-duce the medical expenditure burden on patients. To test the hypothesis, the panel data method has been adopted based on the data of 23 tertiary hospitals. Empirical results find that:(1) increases in itemized subsidies will reduce the burden of medical expenses on patients;(2) conversely, the impact of itemized subsidies on outpatient medical expenses is more sig-nificant. By sharing a portion of public hospital expenses and impacting hospital service providing behavior, itemized sub-sidies help to reduce the burden of medical expenses on patients.
