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 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.

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 utility of the diagnosis and typing to the ureterocysts using ultrasonography.Methods Based on the difference of anatomical location and appearance of cysts.the ureterocysts were divided into 4 types as fllowing:⑴Type of inside bladder:ureterocysts completely location in the inside of bladder.⑵Type of outside bladder:ureterocysts completely location in the outside of bladder.⑶Type of mixture:a part of cysts location in the inside of balader and other part localed in the outsider.⑷Type of ectopia:rare,cysts location in the neck of bladder or urethra usually complicated whith double kidney and abnormal location in the end of the ureter.Results UItrasonographic manifestations of 15 cases for ureterocele were reported.There were 3 cases of bilateral ureterocele and 18 cysts with a diameter 0 4cm～6 0cm. In which ,Type of inside bladder had 8 cases with 9cysts altogether .Type of outside bladdder had 2cases with 2 cysts only,Type of mixture had 5cases with 7 cysts;Type of ectopia had no one in this report .All cases were confirmed by ureteropyelography,in which,6 cases confirmed by surgical pathological examinations.Conclusion Ultrasonography has a high clinical value in the diagnosis and typing of ureterocele.

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.
