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.

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 investigate the application value of plasma D-dimer and coagulation indicators in the patients with o-varian cancer by detecting the routine coagulation indicators and plasma D-dimer level.Methods The plasma D-dimer and coagula-tion indicators levels were measured in 84 patients with ovarian cancer and 25 patients with benign ovarian tumor.The application value of preoperative plasma D-dimer level in monitoring the disease course of ovarian cancer was evaluated.Results The plasma levels of D-dimer and FBG in the ovarian cancer group were significantly higher than those in the ovarian benign tumor control group(P <0.01);moreover the plasma levels of D-dimer and FBG in the patients with the stage Ⅲ~Ⅳ ovarian cancer were signifi-cantly higher than those in the patients with the stageⅠ~Ⅱ ovarian cancer,the differences had statistical significance(P <0.05), which prompting that the coagulation and fibrinolysis dysfunction in the patients with ovarian cancer exhibited the aggravating trend with the disease condition progression.Conclusion D-dimer may reflect the excessive activation of fibrinolysis function in ovarian tumor,which prompting the survival period and prognosis in the patients with advanced ovarian cancer.The plasma D-dimer level has the important significance to early prevention,early diagnosis,early treatment and improve the prognosis in the thrombosis oc-currence in ovarian cancer.

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.
