Objective To investigate the efficacy of integrated traditional Chinese medicine (TCM) with Western medicine in treatment of diarrhea type irritable bowel syndrome (IBS-D) and its effect on serum inflammatory cytokine levels.Methods One hundred and sixty four IBS-D patients treated in Guangfu Hospital from July 2013 to August 2015 were randomly divided into study group and control group with 82 cases in each group.All patients received oral Saccharomyces boulardii 1.0 b.i.d, while patients in study group received additional Shuganjianpi decoction b.i.d for 4 weeks.The clinical efficacy was observed, serum IL-10, IFN-γ and TNF-α levels were measured in 2 groups.Results After treatment, the total score of clinical symptoms in study group was lower than that of control group [(5.71±1.41) vs.(11.70±2.88) points,t=16.707, P<0.01].Serum levels of IFN-γ, TNF-α in study group decreased significantly after treatment [IFN-γ (2.88±1.38) ng/L vs.(1.00±0.44) ng/L, t=11.609, P<0.01;TNF-α (41.26±5.29) ng/L vs.(24.13±3.27) ng/L,t=24.636, P<0.01], IL-10 significantly increased [(142.23±21.58) ng/L vs.(170.23±33.45) ng/L,t=6.291,P<0.01].The overall effective rate of study group was higher than that of control group, [87.50% (70/80) vs.68.75% (55/80), x2=8.228, P<0.01].After treatment, the quality of life scores in both groups were improved;but the improvement of diet, spirit, mood and sleep scores in study group were better than those in control group [(240±69) vs.(193±60), t=4.579, (316±74) vs.(230 ± 69), t=7.603, (297±62) vs.(228±59), t=7.211;(284±62) vs.(230±54), t=5.874, all P<0.01].Conclusion The efficacy of integrated traditional Chinese medicine with Western medicine in treatment of IBS-D is significantly better than that of Western medicine alone, which may be associated with its regulatory effect on the serum inflammatory cytokine levels.

ObjectiveTo investigate the diagnostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) and MB isoenzyme of creatine kinase (CK-MB) for heart failure (HF) in pneumonia children.MethodsThe NT-proBNP and CK-MB were assayed in 132 pneumonia children with HF, 138 pneumonia children without HF and 62 healthy children were recruited into this study. A receiver operating characteristics (ROC) curve and a logistic regression model were employed to assess the diagnostic accuracy of NT-proBNP and CK-MB for HF in pneumonia children.ResultsPneumonia children with HF had higher blood NT-proBNP and CK-MB than those in pneumonia children without HF and healthy controls (P<0.01 for both). Pneumonia children with HF had higher blood NT-proBNP and CK-MB than the pneumonia children without HF. The area under curves (AUCs) of NT-proBNP and CK-MB for HF were 0.85 and 0.72, respectively. The AUC for their combinational usage was 0.87.ConclusionBoth NT-proBNP and CK-MB are effective markers as diagnostic adjuncts for HF in pneumonia children. Combination of NT-proBNP and CK-MB can improve the diagnostic accuracy for HF in pneumonia children.

To express feruloyl esterase A from Aspergillus oryzae in Pichia pastoris expression system and study its hydrolysis function, explore the conditions and effects of purification for ferulic acid extracts by macroporos resin. Using the total RNA from A. oryzae CICC 40186 as the template, we amplified coding sequence AorfaeA encoding a mature feruloyl esterase A (AorFaeA) by RT-PCR technique. Then, the coding sequence AorfaeA was successfully expressed in Pichia pastoris GS115 mediated by an expression plasmid pPIC9K. The purified recombinant AorFaeA (reAorFaeA) showed one single band on SDS-PAGE with an apparent molecular weight of 39.0 kDa. The maximum activity of reAorFaeA to methyl ferulate, measured by high-performance liquid chromatography (HPLC), was 58.35 U/mg. Then, reAorFaeA was used to release ferulic acid from de-starched wheat bran in the presence of xylanase. The purification tests for ferulic acid from the enzymatic hydrolysate were carried out with preselected macroporous resins. The results showed that macroporous resin HPD-300 had much higher adsorption and desorption capacities. Ferulic acid could be quantitatively recovered by 50% of the eluent concentration at a flow speed of 1 mL/min. Under the purification condition, the recovery ratio of ferulic acid was 92%, and the content of ferulic acid was increased from 0.13% in the raw material to 10.55%. This work exploits the breakdown of ferulic acid by recombinant enzymeand provids a good strategy to its "green production".
