By using the method of philology, 65 Hui prescriptions for treating cough were been collected to compare Arabic and Chinese names of pennisetum, anemarrhenae, honey, pease, white mustard, perilla and towel gourd stem. The Countif function in Microsoft Excel 2007 was used to count frequency of drugs in the prescriptions and summarize eight common Hui medicine for treating cough, namely sugar, honey, almond, fritillaria, liquorice, orange peel, white mulberry root-bark and lily. According to the commonly used drugs, philological studies and theories of Hui medicines, pathology and therapy of Hui medicines for treating cough were preliminarily inferred. In this study, 35 practical prescriptions and 30 simple and convenient Halal dietary prescriptions were summarized from collected prescriptions according to relevant literatures. On the basis of the long-lasting unique dietary therapy culture developed for Hui people, the simple and practical dietary prescriptions were defined according indications, therapy, prescription name and composition, and eight types of drug-admixed foods were summarized to relieve pains and improve health awareness and quality of life. Meanwhile, this study could also enrich and perfect the prescriptions, provide new ideas for improving health of patients, and lay a certain realistic foundation for further study of Hui medicines.

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

Objective To analyze the impac factors of serum N?terminal pro?brain natriuretic peptide (NT?proBNP) in patients with renal failure in non?dialysis phase, and to determine the cut?off point of as a diagnostic values in these patients with heart failure (HF). Methods Cross?sectional study was applied. Clinical data of 145 patients (37 cases of CKD4, 89 cases of CKD5, and 19 cases of acute renal injury (AKI) with renal failure in non?dialysis phase were collected. Comparison between groups and lineal regression analysis were utilized to investigate the impact factors of NT?proBNP, and the receiver operating characteristic curve (ROC curve) to select a better cut?off point of diagnosis in these patients with HF. Results (1) Compared with patients without HF, patients with HF had significantly higher edema, cardiac troponin I, serum phosphorus concentration, and left atrial diameter (LA), while ALB and left ventricular ejection fraction (LVEF) were decreased (P<0.05). (2) The NT?proBNP was divided into 4 groups with four points: First groups of 36 cases, NT?proBNP 1 ?862 ng/L, second groups 37 cases, 866?2670 ng/L, third groups 37 cases, 2790?20 000 ng/L, fourth groups 35 cases, 20 900?35 000 ng/L. With the increase of NT?proBNP levels, the occurrence of AKI and CKD4 decreased gradually while the occurrence of CKD and edema were significantly increased (P<0.01). Systolic blood pressure, troponin I, uric acid, serum phosphorus, parathyroid hormone, 24 hours urine protein, LA, interventricular septum thickness (IVS), left ventricular posterior wall thickness (LVPW) level gradually increased. Hb, ALB, calcium, CO2, eGFR, LVEF significantly decreased (P<0.01). The serum NT?proBNP of patients with HF was significantly higher than that of patients without HF (19 150 ng/L vs 1530 ng/L, P<0.01). The serum NT?proBNP of patients with edema was significantly higher than that in patients without edema (5460 ng/L vs 1630 ng/L, P<0.01). (3) Single factor linear regression analysis indicated that higher NT?proBNP was positive correlated with HF, edema, cardiac troponin I, uric acid, serum phosphorus, LA, IVS and LVPW (P<0.05), while negative correlated with Hb, eGFR, ALB, serum calcium, CO2, LVEF (P<0.05), and not correlated with eGFR, uric acid, serum calcium (P>0.05). (4) The best cut?off point of NT?proBNP predicting HF in patients with renal failure in non?dialysis phase was 3805 ng/L, AUC=0.848, 95%CI 0.786?0.910. Sensitivity was 82.4%, specificity 74.5%, positive predictive value 62.1%, negative predictive value 87.3%, positive likelihood ratio 3.2, negative likelihood ratio 0.24. Conclusions The level of NT?proBNP>20 000 ng/L is mainly found in end?stage renal disease patients with HF. HF is a main factor for the increase of NT?proBNP in patients with renal failure in non?dialysis phase. High phosphorus viremia, anemia, and hypoalbuminemia are closely related to NT?proBNP. Therefore NT?proBNP predicting HF should take into account the effects of these confounding factors in these patients.
