Many researches proved that inflammation plays a decisive role in occurrence, development and prognosis of acute coronary syndrome (ACS).Atorvastatin possesses many other effects besides lipid regulation, and anti-inflammatory effect is the most significant one.Some studies indicated that atorvastatin can reduce levels of high sensitive C reactive protein (hsCRP), interleukin (IL)-6 and tumor necrosis factor (TNF)-α in ACS patients, then inhibit postoperative inflammation, improve postoperative blood flow perfusion and reduce occurrence of acute coronary events.The present article made a review on influence of atorvastatin on levels of hsCRP, IL-6 and TNF-α in ACS patients.

Objective To investigate the physiological responses of healthy youth to doing chest compression as a feedback of quality of CPR after their rapid ascent to high altitude and to evaluate the feedback in the intervention effects of CPR.Methods Prospective,single sample,before-after comparison method was used in this study.Fifteen young adults from plains natives were enrolled as trial subjects in this study.All of them received basic life support training course in advance.In Chongqing (259 m above sea level),subjects performed empiric chest compressions on the model body for 4 minutes followed by feedback compressions for 4 minutes after at least 30 minutes rest.Compression depth,rate and other compression quality parameters were measured and recorded at each turn of compressions with an AED PLUS device.Subjects performed empiric compressions based on their knowledge and experiences,and practiced feedback compressions according to the audiovisual guidance of AED PLUS device.Blood pressure,heart rate and SpO2 were taken before and after each turn of compressions.One week after arrival to Lhasa (3658 m above sea level) by flight,all subjects were asked to do the same procedure as did in Chongqing to see their physiological response to.Paired t tests or Wilcoxon matched pair rank test were used for comparisons of measurements before and after trials.Results Systolic pressures,diastolic pressures,heart rates at baseline in Lhasa were significant different from those in Chongqing,including systolic pressure (125.9 ±9.5) mmHg vs.(112.7 ±13.4) mmHg,diastolic pressure (75.3 ±7.7) mmHg vs.(64.2 ±7.3) mmHg,heart rate (86.3 ± 13.0) beat/min vs.(72.7 ± 11.6) beat/min,SpO2 (90.4 ± 1.7)％ vs.(97.8 ±0.9)％,all P ＜ 0.01.In Lhasa,empiric compressions only caused an increase in heart rate (91.1 ± 14.9) beat/min vs.(86.3 ± 13.0) beat/min,P ＜ 0.01.However,feedback compressions resulted in a significant decrease in SpO2 [(88.3 ± 3.4) ％ vs.(90.6 ± 1.9) ％,P ＜ 0.01] as well as change of systolic pressure [(130.9 ± 11.7) mmHg vs.(120.1 ± 11.9) mmHg,P ＜0.05] and heart rate [(87.9 ± 17.5) beat/min vs.(80.9 ± 11.7) beat/min,P ＜0.05].In Lhasa,the compression quality during feedback compressions was closer to guideline recommendation than that during empiric compressions.The median (interquartile range) of composite qualification rate was 43.6％ (55.9％) vs.0.6％ (5.3％) during feedback compressions and empiric compressions respectively,P ＜ 0.01.Conclusions Compression quality decreased significantly among youth after rapid ascent to high altitude.Feedback techniques for CPR could effectively guide the rescuer to improve their CPR quality,but it may be at the expense of more physical consumption.

Objective To investigate the expression of Interleukin 6 ( IL-6 ) and interleukin 10 (IL-10) in cerebrospinal fluid(CSF) in patients with primary central nervous system lymphoma.Methods Forty cases of primary central nervous system lymphoma ( PCNSL) , 11 cases of secondary central nervous system lymphomas( SCNS) , 20 cases of brain metastase, 20 cases of central nervous system infection and 16 cases of other nervous system disease( ONSD) were collected during the period from July 2013 to December 2015 in Fudan University Hua Shan Hospital North.Enzyme linked immunosorbent assay was used to detect the levels of IL-6 and IL-10 in serum and cerebrospinal fluid.The overall level of each group was compared using Kruskal-Wallis test.Two independent samples were compared by U Mann-Whitney test.The diagnostic value of IL-6 and IL-10 levels for PCNSL was evaluated by ROC curve.Results In PCNSL group, BM group, SCNSL group, CNSI group and ONSD group, the serum levels of IL-6 and IL-10 were not statistically significant ( H values were 4.165 and 5.368, respectively, P>0.05).IL-6 levels in CSF were significantly higher in CNSI[623.73 (1018.77-184.37) pg/ml] than those in other groups ( ZPCNSL =51.36, ZSCNSL =28.18, ZBM =51.50, ZCNSI =85.45, ZONSD =42.16, P<0.05 ) .The levels of IL-10 in CSF were significantly higher in CNSI and PCNSL than those in other groups ( ZPCNSL =74.50, ZSCNSL =34.68, ZBM =35.35, ZCNSI =72.95, ZONSD =15.66, P<0.05).The levels of IL-10 in CSF in PCNSL group[64.88(20.03-206.14)pg/ml]was significantly higher than in SCNSL group[6.28(2.78-18.87)pg/ml, Z=-3.753,P<0.05], BM group[7.30(3.72 -14.49) pg/ml, Z=-5.034,P<0.05] and ONSD group [3.14(2.931-4.20)pg/ml, Z=-5.786,P<0.05].The area under the ROC curve of IL-6 and IL-10 levels in CSF was 0.461 and 0.806 respectively for the diagnosis of PCNSL.When IL-10 was 19.62 pg/ml, the sensitivity was 77.5% ( 31/40 ) and the specificity was 70.1% ( 47/67 ) .The area under the ROC curve of CSF IL-6 and IL-10 levels was 0.861 and 0.718 respectively for the diagnosis of CNSI.When IL-6 was 155.12 pg/ml, the sensitivity was 80.0% (16/20) and the specificity was 90.8% (79/87).When IL-10 was 26.76 pg/ml, the sensitivity was 80.0% ( 16/20 ) and the specificity was 66.7% ( 58/87 ) . Conclusion The expression levels of IL-6 and IL-10 in CSF can be used as an indicator for the differential diagnosis of primary central nervous system lymphoma.

Objective To observe the neural protective subsidiary effect of Wenyang Yiqi method on patients with severe traumatic brain injury under mild hypothermia therapy.Methods A prospective study was conducted in which 53 patients with severe traumatic brain injury treated by mild hypothermia were randomly divided into control group (26 cases) and observation group (27 cases). All the patients in the two groups received conventional western treatment combined with mild hypothermia therapy. In the observation group, additionally was given the representative drug of Wenyang Yiqi method, Shenfu injection 100 mL mixed into 5% glucose 500 mL intravenous drip once a day. At the end of mild hypothermia, the Shenfu injection was stopped. After treatment, the changes of intracranial pressure (ICP) on 1 (the day the treatment began), 2, 3, 4, 5, 6 and 7 days and the indexes levels, including S-100B, lactate dehydrogenase (LDH) and creatinkinase (CK) in the cranial spinal fluid (CSF) before treatment and 2, 4, 6 days after treament (CSF) were observed. The Glasgow coma score (GCS) before treament and 3, 5, 7, 14, 28 days after treament, and Glasgow outcome scale (GOS) on 28 days and 3 months after treatment were recorded, and the incidences of complications were calculated at the end of therapy.Results After treatment with the prolongation of therapeutic time, the levels of ICP were gradually increased in two groups and reached the peak values on the 4th day, then beganto fall, and on the 5th day it was significantly lower in observation group than that in control group [ICP (mmHg, 1 mmHg = 0.133 kPa): 16.11±1.23 vs. 18.73±1.42], persisting the same situation to the 7th day (14.17±0.80 vs. 16.94±1.00,P < 0.05). The levels of S-100 B in the two groups were progressively decreased after the treatment, on the 2nd day it was significantly lower in observation group than that in control group (μg/L: 1.21±0.43 vs. 1.86±0.57, P < 0.05), also persisting to the 6th day (0.40±0.09 vs. 0.94±0.15,P < 0.05); the levels of LDH and CK reached the peak values on the 2nd day, then began to fall, they were significantly lower in the observation group than those in the control group on the 4th day [LDH (U/L): 63.43±12.21 vs. 80.11±14.34, CK (U/L): 52.41±14.14 vs. 88.37±12.21, bothP < 0.05], and on the 6th day still there were statistically significant differences between the two groups. The GCS before treatment showed no statistically significant difference between the two groups (P > 0.05); after treatment, the GCS score of the two groups was progressively improved, and on the 14th day the score in the observation group began significantly higher than that in the control group (11.74±1.24 vs. 9.41±2.11,P < 0.05), persisting the same situation to the 28th day (12.68±2.51 vs. 10.67±1.99,P < 0.05). On the 28th day after treatment, the GOS showed no statistically significant difference between the two groups (2.35±0.16 vs. 2.43±0.22,P > 0.05), but the score in the observation group was significantly higher than that in the control group after treatment for 3 months (4.11±0.38 vs. 3.72±0.41, P < 0.05). The incidences of complications in the observation group were significantly lower than those in the control group [respiratory failure: 25.9% (7/27) vs. 50.0% (13/26), shock: 18.5% (5/27) vs. 53.8% (14/26), acute pulmonary edema: 14.8% (4/27) vs. 30.8% (8/26), stress ulcer: 22.2% (6/27) vs. 57.7% (15/26), hypoproteinemia: 40.7% (11/27) vs. 73.1% (19/26), allP < 0.05].Conclusion Wenyang Yiqi method has the subsidiary neural protective effect on patients with severe traumatic brain injury treated by mild hypothermia, and can improve their outcome.
