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.

Along with the development of computer technologies and digitization of human body's information, the digital human entered into a new stage of modelling physical features from the stage of reconstructing anatomical structures. By summarizing domestic and abroad relevant documents, we in this paper present the general scheme of digital human and the location of physical human as well as its conception and applied value. We especially analyze the modeling process of physical human, core technologies and its research and applications in four main fields: electromagnetic radiation, ultrasound propagation, bioimpedance measurements and biomechanical analysis. We also analyze and summarize existing problems of present physical human model and point out the future development trends of physical human.

Aims To establish several behavioral paradigms to characterize the psychotropic effects of hallucinogens which ze-brafish was utilized as a model animal, and then to investigate the effects of potent hallucinogenic drugs on these models. Methods With the video record and track system, the behavior was recorded and quantified automatically. In the experiments, the bottom dwelling test, social behavior and mirror test were performed to test the hallucinogenic effects of drugs. Metham-phetamine (METH, 2 mg·L-1) and ketamine (20 mg·L-1) were selected as experimental challenges. The 30 min pre-treat-ment time was chosen based on our prior experience in zebrafish models. Results Compared to the normal group, in dwelling test, acute exposure of zebrafish to METH and ketamine de-creased transitions significantly, and in mirror reflection test, the drug-treated fish changed the preference for mirror zone, and ex-hibited aggressive for their mirror images. The pretreatment of METH and ketamine significantly reduced the contact durations, and the ketamine inhibited the contact frequency each other, the results indicated that the social interaction of zebrafish was im-paired. Conclusion The results confirm high sensitivity of ze-brafish models to hallucinogenic compounds with complex behav-ioral and physiological effects.

Objective To evaluate the curative effect of hysteromyoma uterine treated by uterine artery embolization (UAE) with color Doppler ultrasound.Methods Seventeen patients with hysteromyoma uterine were examined by color Doppler ultrasound before and after uterine artery embolization wthin half year monthly,observing the size, morphology,internal echotexture and Doppler signal of the uter and its myoma,measuring their Doppler indices of uterine artery,peripheral and internal vascular in myoma.Results There was significant difference of the average volume of the uterus and its myoma between pre-operation and post-operation( 435.18 cm 3 vs 222.51 cm 3, 102.47 cm 3 vs 52.10 cm 3,respectively, P

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.
