Objective To explore the effect of recombined Human epidermal growth factor (rhEG) combined with alprostadilon Wnt/β-Catenin signal pathway in rats with diabetic ulcer. Methods Rats with diabetic ulcer were randomly divided into four groups :control group ,rhEG group ,epidermal group and combined treatment group. Ulcer skin was smeared by normalsaline in control group ,and by rhEG in rhEG group. Epidermal was administered from caudal vein in epidermal group.Combined treatment group was treated by rhEG and epidermal at the same time. The healing status were observed. The proteinand mRNA expression of Wnt-1 ,β-Catenin and GSK-3β were measured 14 days after treatment. Results The healing rates in combined treatment group were (9.76 ± 2.37 )% ,(35.74 ± 3.65 )% ,(51.37 ± 4.16)% and (84.42 ± 5.35 )% respectivelyin 6th , 10th and 14th day after treatment , which were significantly higher than in rhEG group and epidermal group (P<0.05). The mRNA levels of Wnt-1 ,β-Catenin and GSK-3βin combined treatment group were (1.42 ± 0.19) ,(1.56 ± 0.21) and (0.95 ± 0.15) after treatment for 14 days ,which were significantly higher than in rhEG group and epidermal group (P<0.05). Protein levels of Wnt-1 ,β-Catenin and GSK-3βin combined treatment group were (1.17 ± 0.16) , (1.38 ± 0.18 ) and (0.81 ± 0.13 ) after treatment for 14 days ,which were significantly higher than in rhEG group and epidermal group ( P < 0.05 ). Conclusion rhEG combined with epidermal can significantly accelerate the healing of diabetic ulcer ,and can regulatethe Wnt/β-Catenin signal pathway by increasing the expression of Wnt-1 ,β-Catenin and GSK-3β.

Objective To explore the characteristics of the interactions between traditional laxative medicine Cannabis Fructus and human gut microflora. Methods HPLC method was used to determine the content of the main unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction. At the same time, solid culture and liquid culture in vitro anaerobic culture method were combined with 16 S rRNA technology to analyze the interactions between Cannabis Fructus Decotion and human gut microflora. Moreover, the metabolits of linoleic acid and linolenic acid in Cannabis Fructus Decoction by human intestinal microflora were determined using HPLC method. At the same time, the possible conjugated linolenic acid and linoleic acid were determined. Results Cannabis Fructus Decoction promoted the growth of Proteobacteria significantly, which showed that Escherichia-shigella was significantly increased (P < 0.01), but the growth of Bacteroidetes was decreased (P < 0.01), and the content of unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction were reduced after being incubated with human intestinal bacteria, and the metabolites were conjugated linoleic acid and conjugated linolenic acid. Conclusion The interactions between Cannabis Fructus Decoction and human intestinal microflora are obvious. The Chinese medicine can change the structure of the gut microflora, and the gut microflora can metabolize the drug components. This analysis method partially restores the pharmacokinetics process of the oral administration drug in the human intestinal tract. It could provide a new insight of the mechanism research of Cannabis Fructus.

Amyotrophic lateral sclerosis(ALS)is a rare progressive motor neuron disease.Sialorrhoea is one of the common symptoms which influenced the patient's quality of life.This paper reviewed the treatments for sialorrhoea in ALS patients.

Objective To explore the effects of fibroblast transdifferentiation for myofibroblast (MFB) in the pathogenesis of systemic sclerosis (SSc) and to explore the antifibrotic mechanism of interferon γ (IFN-γ) in SSc.Methods The fibroblasts derived from the skin lesions of SSc patients and healthy adult controls were cultured in vitro and the MFB proportion in fibroblasts was examined by qualitative and quantitative α-smooth muscle actin (α-SMA) detection.By adding IFN-γ to the culture system with several doses,the influence on fibroblast proliferation and transdifferentiation for MFB in SSc was observed with MTT and enzyme linked immunosorbent assay (ELISA) respectively.Differences in the means of two independent samples were tested by Student' t-test.The means among multiple independent samples were com-pared by ANOVA.Results The means of positive α-SMA in SSc fibroblasts were higher than those in the controls (P＜0.01).With extended culture time,α-SMA levels of the two groups all increased gradually (P＜ 0.01 all),but there were higher α-SMA levels in SSc fibroblasts (24 h:130±19,48 h:183±21,72 h:249± 22) than those in controls (24 h:98±21,48 h:143±16,72 h:174±19) (P＜0.05 all).Although fibroblast proliferation and α-SMA levels were not influenced after adding of IFN-γ 10 U/ml (P＞0.05 all),but IFN-γ at concentration of 100 U/ml and 1000 U/ml could obviously repress fibroblast proliferation and α-SMA levels (P＜0.05 all),and 1000 U/ml had the strongest inhibiting effect at 24,48,72 h.Conclusion The fibroblasts in the skin of SSc patients have a strong potency to transdifferentiate to MFB.Early appropviate dose of IFN-γ could repress fibroblast proliferation and transdifferentiation in SSc.

Objective To perform the comparative analysis on the use situation of 3 kinds of dry chemical analyzers according to the industrial standards YY/T0655-2008.Methods With the Roche Cobas P800 automatic biochemical analyzers as the reference instrument,the accuracy,intra-assay precision,linearity,etc.in 3 kinds of dry chemical analyzers were evaluated.Results 3 kinds of dry chemical analyzers met the requirements of the industrial standards YY/T0655-2008,but the precision of imported instrument was significantly better than that of the domestic instrument.Conclusion In order to ensure the comparability and consistency of the detection results among instruments,the instruments should be regularly calibrated and performed the comparative experi-ments,the premise of calibration and comparison should be using 1/4 of the precision level in the CLIA′88 indicators as the indica-tor,not satisfying with the precision requirements in YY/T0655-2008,only in this way can the waste of blood and donors going a-way be avoided.
