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.

Objective To evaluate the diagnostic value of ~(99)Tc~m-methoxyisobutylisonitrile (MIBI) SPECT scintigraphy combined Iocalizable CT in the localization of ectopic parathyroid glands in hyperparathyroidism.Methods Retrospective data of surgery,pathology and imaging were collected from 28 patients with hyperfunctioning ectopic parathyroid glands.All cases underwent CT studies.Twenty-five patients had ~(99)Tc~m-MIBI planar imaging first:SPECT scintigraphy combined localizable CT was performed for the patients with abnormal radionuclide foci immediately.The fusion images obtained after reconstruction showed the exact location of the ectopic foci.Operative histopathologic results were regarded as "gold standards".Presuming 4 parathyroid glands as normal findings,findings confirmed by operation and pathology were regarded as positive,otherwise negative.The results of CT and radionuclide imaging were compared by X~2-test of four-foId table.Results Twenty-eight ectopic parathyroid glands were found in 28 patients,all pathologically confirmed as adenomss.CT found 22 foci,of which 17 were true positive,5 false positive,11 false negative,and 79 true negative.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT found 23 foci,no false positive,2 false negative,and 75 true negative.The results showed that the sensitivities were 61% (17/28),92%(23/25),specificities 94%(79/84),100%(75/75),accuracies 86%(96/112),98% (98/100),positive predictive values 77%(17/22),100%(23/23),and negative predictive values 88% (79190),97%(75/77),respectively,for CT and radionuclide imaging.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT was therefore significantly higher than CT in sensitivity(X~2=6.98,P＜0.01),specificity (X~2=4.61,P＜0.05),accuracy (X~2=10.30,P＜0.01),positive predictive value(X~2=5.88,P＜0.05) and negative predictive value (X~2=5.36,P＜0.05).Conclusion ~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT is superior to CT alone in the localization of ectopic parathyroid glands in hyperparathyroidism,but false negative can be found in some patients.

BACKGROUND:Current research on mesenchymal stem cels (MSCs) is mostly focused on its immune regulatory function, while little is reported on the antioxidant capacity of the cels and culture supernatant.OBJECTIVE: To investigate the anti-oxidative capacity of the supernatant harvested from human fetal placenta MSCs (fPMSCs) under a condition of serum free culture. METHODS:fPMSCs were cultured with serum free media, and the supernatants of cels at passages 2-6 were colected at 48 hours after culture. Vitamin C was added into the culture medium, as a positive control, and its concentration was 100 μmol/L. The total antioxidant capacity, scavenging capacity of free radicals and antioxidant enzymatic activities of supernatants were measured. RESULTS AND CONCLUSION: By comparing anti-oxidative activities of vitamin C and na?ve culture medium, supernatants colected from fPMSCs cultures exhibited obvious antioxidant capacities at different extents between passages of cel cultures. The total antioxidant capacity of the culture supernatant was comparable to 40-80 μmol/L vitamin C. In addition, al supernatants derived from cels with different passages displayed capacities to scavenge free radicals, including 2,2-diphenyl-1-picrylhydrazyl radical (DPPH?), hydroxyl radical (?OH), superoxide anion radical (O2-). Even more, activities of antioxidant enzymes, including superoxide dismutase and glutathione peroxidase, were also detected in supernatants colected from different passages of fPMSCs. Under the serum-free condition, the culture supernatants of fPMSCs have antioxidant capacities at certain extent. However, the antioxidant components and underlying mechanisms need to be further studied.
