Objective: To observe the effect of edaravone combining ulinastatin on brain protection in patients of type A aortic dissection (AAD) after total arch replacement. Methods: A total of 60 AAD patients with total arch replacement in our hospital from 2014-09 to 2016-01 were prospectively studied. Based on peri-operative application of edaravone and ulinastatin, the patients were divided into 2 groups: EU group: 1) the patients received ulinastatin 300000 U/8h and edaravone 0.5mg/Kg/12h from administration to 3 days post-operation, 2) during cardiopulmonary bypass, the patients received ulinastatin 300000 U/2h and edaravone 0.5mg/Kg; Control group, the patients had no such treatment.n=30 in each group. The following items were observed:①operative condition;②blood levels of speciifc brain injury markers as S-100 and neuron speciifc enolase (NSE) at different time points: beginning of surgery (T0), opening aorta clamp (T1), right after cardiopulmonary bypass (T2), entering ICU (T3), 24h post-operation (T4) and 3 days post-operation (T5); ③post-operative condition. Results:①Durations of operation, cardiopulmonary bypass, cardiac arrest and bilateral antegrade selective cerebral perfusion (BACP), the frequency of BACP and UACP (unilateral antegrade selective cerebral perfusion), the lowest rectal temperature and blood levels of S-100, NSE at T0 were similar between 2 groups.②Compared with Control group, EU group had decreased S-100 and NSE from T1 to T5,P<0.05.③The in-hospital and ventilation time, frequency of PND and TND, the patients with CSS score≥16 before discharge and the in-hospital death rate were similar between 2 groups,P>0.05. Conclusion: Edaravone combining ulinastatin had brain protective effect in AAD patients after total arch replacement;it may reduce blood speciifc brain injury markers while the clinical signiifcance should be further investigated.

OBJECTIVETo observe the curative effect of Shenyanning (SYN) on non-nephrotic syndrome IgA nephropathy (IgAN).

METHODSSeventy primary IgAN patients were equally randomized into two groups, the treatment group and the control group, they were orally treated with SYN Decoction (one dose per day) and Losartan (50 mg per day) respectively for 1 year. Efficacy of treatment, Chinese medicine syndrome scores, end-point events occurrence as well as changes of related laboratory indices were observed.

RESULTSThe total effective rate in the treatment group was obviously higher than that in the control group (77.1% vs. 54.3%, P < 0.05). After treatment, the Chinese medicine syndrome scores, urinary protein and urinary red-cell count reduced significantly in the treatment group (P < 0.05 or P < 0.01) and showed significant difference as compared with those in the control group (P < 0.05 or P < 0.01); while the endogenous creatinine clearance was changed insignificantly in both groups. Beside, the occurrence of end-point events in the treatment group was slightly lower than that in the control group, though showed no statistical difference between them.

OBJECTIVETo observe the effect of Wenyang Huazhuo Tongluo Recipe (WYHZTLR) on the proportion of T helper 17 cells (Thl7)/regulatory T cells (Treg), and serum levels of IL-17 and IL-10 in peripheral blood of systemic sclerosis (SSc) patients with yang qi insufficiency and turbidity induced collaterals blockage syndrome (YQITICBS).

METHODSTotally 82 SSc patients were randomly assigned to the Western medicine group (as the control group) and the integrated Chinese and Western medicine group (as the treatment group), 41 cases in each group. All patients took methotrexate (MTX) tablet and prednisone tablet. Patients in the treatment group additionally took WYHZTLR. The treatment course for all was six consecutive months. Besides, another 70 healthy volunteers were recruited as a healthy control group (as the healthy group). Percentages of Th17 and Treg in peripheral blood were detected by flow cytometry. Serum levels of IL-17, IL-10, von Willebrand factor (vWF), aminoterminal propeptide of type l procollagen (PIIINP), and cross-linked carboxyterminal telopeptide of type I collagen ( I CTP) were measured by double antibody sandwich ELISA. The correlations between Th17/Treg and levels of vWF, PIIINP, I CTP, skin score, and disease activity index were observed by Pearson correlation analysis.

RESULTSThe percentage of Th17 in peripheral blood, ratios of Th17/Treg, and the serum level of IL-17 were significantly higher, but the percentage of Treg and the serum level of IL-10 were significantly lower in SSc patients, when compared with those of the healthy group (P <0. 05, P <0. 01). Compared with the same group before treatment, the percentage of Thl7, ratios of Thl7/Treg, and levels of IL-17, vWF, and PIIINP all decreased in the two groups after treatment (P <0.05, P <0.01), but the percentage of Treg and the IL-10 level increased (P <0. 05, P <0. 01). Meanwhile,the level of I CTP was higher in the treatment group after treatment (P <0. 05). The improvement of all indices except the percentage of Th17 was more obvious in the treatment group than in the control group (P <0. 05, P <0. 01). The ratio of Th17/Treg was positively correlated with levels of vWF, PIIINP, skin score, and disease activity index before and after treatment respectively (P <0. 01), but with no obvious correlation with the level of I CTP (P >0. 05).

CONCLUSIONWYHZTLR could achieve its therapeutic effect on SSc patients by regulating Th17/Treg imbalance, lowering levels of vWF and PIIINP, and elevating the level of I CTP.

Objective To explore the biological exposure limit of liver dysfunction induced by arsenic-coal burning, and screen sensitive biornarkers for its' liver dysfunction monitoring. Methods One hundred and eighteen subjects from the exposed area and 50 control from non-pollution area were studied. Their urinary and hair contents of arsenic were tested as exposure biomarkers by Ag-DDC assay. Total bile acid(TBA, detected by enzymatic cycling method), glutathione S-transferase (GSTs, detected by chemical colorimetry) and γ-glutamyl transpeptidase (γ-GT, detected by colorimetry of diazotization reagent) were used as biomarkers indicating liver cell damage. were used as liver fibrosis biomarkers. The benchmark dose (BMD) and the lower confidence limit of benchmark dose(BMDL) of urinary and hair arsenic were calculated. Sensitivity of each biomarker was estimated according to the BMD and BMDL value. Results The geometric mean of urinary and hair arsenic(98.50 mg/kg Cr, 7.42 mg/kg) μg/L) in the exposed group were significantly higher than urinary and hair arsenic (22.98 mg/kg Cr, 1.28 mg/kg) and each biomarker in the control group(4.63 μmol/L, 13.76 U/L,36.45 U/L,54.62 μg/L,74.45 μg/L,54.81 μg/L, P<0.01). Significant dose-effect relationship existed between urinary and hair arsenic contents and each biomarker. BMD and BMDL value of urinary arsenic was 49.53-101.96 mg/kg Cr and 39.02-70.15 mg/kg Cr, respectively. Those of hair arsenic were 3.04-5.02 mg/kg and 2.36-3.25 mg/kg, respectively. According to BMD and BMDL value of urinary and hair arsenic, the sensitivity of biomarkers decreased in the order of GSTs, TBA and Conclusions According to the lowest BMD and BMDL of urinary and hair arsenic, averaged reference value of urinary and hair arsenic in the local normal population, we suggest urinary 35.0 mg/kg Cr and hair 2.5 mg/kg as their biological exposure limits for those with liver dysfunction induced by arsenic-coal burning. GSTs, TBA, γ-GT and HA, Ⅳ. C, PC-Ⅲ can respectively reflect liver cell damage and liver fibrosis caused by arsenic-coal burning in different degrees, among which, GSTs and HA are the most sensitive biomarkers respectively for liver cell damage and liver fibrosis.
