OBJECTIVETo bring forward a method to improve the prominence of the forehead contour.

METHODS16 patients(age 29-53 years, female 11, male 5) were treated through a bicoronal incision. Following the incision, the forehead soft tissues are reflected down to the level of the superior orbital rims with the protection to the supraorbital neurovascular bundles. To adjust the forehead contour, both superior orbital rims and frontal bossing was reduced by burring down the excess bone or removing the anterior wall of the forehead.

RESULTSThe operative effect were satisfactory during 3-12 months of follow-up. No recurrence or osteogenesis were found in the cases. Nasofrontal angle and forehead angle were normal. The prominence of the supraorbital ridges disappeared and forehead became nature.

CONCLUSIONCranioplasty via an osteomy or burring of the outer line of forehead bone are safe, compact and effective way to improve the prominence of the superior orbital rims or frontal bossing.

Objective To compare the different effects of 1% diatrizoate meglumine,2.5% mannitol and water as oral contrasts in PET/CT scan in gastrointestinal tract delineation and 18F-fluorodeoxyglucose (FDG) uptake. Methods Sixty-one patients referred for PET/CT scan without gastrointestinal diseases were divided into three groups randomly ( random number method). One liter of 1% diatrizoate meglumine,2.5% mannitol,or water was orally taken by groups 1 (25 cases),2 (20 cases) and 3 ( 16 cases),respectively before scan. The scan was performed with GE Discovery LS PET/CT scanner in two-dimensional (2D) mode 50 min after 18F-FDG (5.55 MBq/kg) injection. Patients with abdominal lesions were excluded from this study. The degree of gastrointestinal filling and 18F-FDG uptake was evaluated by 3 nuclear medicine physicians using visual analysis according to a 4-grade classification method:none,mild,moderate,and high. Statistically analysis was performed by Kruskal-Wallis,Mann-Whitney and paired t tests.Results Both the differences of serum glucose and insulin levels were not significant before and after contrast taken in group 2. Group 2 had better gastrointestinal filling than that of group 1 and also better than group 3 except in rectum. The stomach,jejunum,ascending,and transverse colon were better filled in group 1 than in group 3. The degree of 18F-FDG uptake of group 3 was significantly higher than that of group 2 in stomach,jejunum and ileum (z= -3. 192,-3.290,-3.290,all P＜0.05),and was also significantly higher than that of group 1 (z = - 3. 603,P ＜ 0.05) in jejunum. The degree of 18 F-FDG uptake of group 3 was significantly lower than that of group 1 in ascending colon (z = - 2. 706,P ＜ 0. 05 ) and was significantly lower than that of group 1 and 2 in transverse and descending colon (z= - 3. 503,- 2.403,- 4.225,-4. 027,all P ＜0.05),and was also significantly lower than that of group 2 in rectum (z = -4. 128,P ＜0. 01 ). The maximum CT values in stomach,jejunum,ileum and ascending colon in group 1 were ( 132 ±23),(191 ±31),(313 ±47) and (374±53) HU,respectively,whose difference was significant (t = -7.088--1.781,all P ＜0. 01 ). Conclusion Oral iso-osmotic mannitol intake has better gastrointestinal filling and less physiological 18F-FDG uptake compared to diatrizoate meglumine and water.

To investigate the function of ALK3 gene, the gene regulation and the signaling pathway related to ventricular septum defect during heart development. The model mice with ALK3 gene knock-out via alpha-MHC-Cre/lox P system were bred. The mRNA expression level of control group was compared with that of experiment group and ALK3 downstream genes were screened using PCR-select cDNA subtraction microarray. The mRNA of control group was extracted from E11.5 normal mouse hearts, and that of experiment group, from E11.5 hearts of mice with alpha-MHC Cre(+/-) ALK3(F/+) genotype. It was found that the mice with ALK3 gene knock-out produced heart defects involving the interventricular septum. The platelet-activating factors acetylhydrolase and the transcription factor Pax-8 and so on, were down-regulated. However, the Protein Tyrosine Kinase (PTK) of Focal Adhesion Kinase (FAK) subfamily and beta subtype protein 14-3-3 were up-regulated in the alpha-MHC Cre(+/-) ALK3(F/-) mice. These data provide support that ALK3 gene played an important role during heart development. The platelet-activating factors acetylhydrolase and Pax-8 genes could be important ALK3 downstream genes in the BMP signaling pathway during interventricular septum development. PTK and beta subtype protein 14-3-3 might be regulatory factors in this pathway.

OBJECTIVETo explore the effects of Di (2-ethylhexyl) phthalate (DEHP) on the testis and testicular gubernaculum of fetal KM mice in vivo and to investigate the mechanism of DEHP-induced cryptorchidism.

METHODSThirty healthy pregnant KM mice were randomly and equally divided into a blank control group, a corn oil control group and a DEHP group. The pregnant mice in the latter group were exposed to DEHP by gavage at the dose of 500 mg/kg body weight per day from gestation day 12 (GD12) through gestation day 19 (GD19). The effects of DEHP were observed on the number of fetuses per pregnancy, the ratio of male to female pups, the weight of the testis, the morphology and location of the testis and gubernaculum, the relative testis-bladder neck distance (TBD) and cranial suspensory ligament (CSL) residual. The expressions of the androgen receptor (AR), estrogen receptor (ER) and actin and proliferating cell nuclear antigen (PCNA) in the gubernaculum were detected by immunohistochemistry.

RESULTSDEHP reduced the testis weight and TBD, induced different degrees of testis maldescent, but produced no obvious effect on the body weight, the number of fetuses per pregnancy, the sex ratio and the testis gubernacular morphology. Under the light microscope, hypotrophy was seen in all the testis seminiferous tubules, spermatogenic cells and Sertoli cells, marked Leydig cell hyperplasia was noted, and the positive expression of AR in the gubernaculum was decreased in the DEHP group (P < 0.01).

CONCLUSIONDEHP could cause dysfunction of the testis gubernaculum via its anti-androgen effect, induce cryptorchidism, and cause dysplasia and dysfunction of Sertoli cells, Leydig cells and spermatogenic cells in fetal mice.
