OBJECTIVETo investigate the morphology change of stomatognathic muscles after zygomatic plasty combined with mandibular angel plasty.

METHODS3D-CT facial soft tissue measurement was performed pre-operative and at 10 days,3 months post-operatively in 59 cases with prominent malar-complex and mandibular angle. The q test (Newman-Keuls method) was used to analyze the variance.

RESULTSThe cross sectional area of masseter muscle and medial pterygoid muscle were both increased at 10 days, reduced at 3 months post-operatively (P < 0.05). The masseter muscle and medial pterygoid muscle cross sectional areas were (4.73 +/- 0.21) cm2 and (3.24 +/- 0.21) cm2 at anterior nasal spine plane, respectively; the pterygoid muscle cross-sectional area was (1.37 +/- 0.35 ) cm2 at the root of coronoid process plane, showing significant difference, when comparing with those before operation (P < 0.05). Lateral pterygoid muscle and temporal muscle had no statistical difference between the pre-and 10 days post-operatively(P > 0.05), however, the temporal muscle was reduced while the lateral pterygoid muscle was increased at 3 months post-operatively. The temporal muscle cross-sectional area was(2.35 + 0.25) cm2 at coronoid process plane; the temporal muscle and lateral pterygoid muscle cross-sectional areas were (1.00 +/- 0.16) cm2 and (3.54 +/- 0.61) cm2 at the root of coronoid process plane, which were significantly different from those before operation (P < 0.05 ).

CONCLUSIONSBecause of osteotomy, muscles attached position are changed in the short term after zygomatic plasty combined with mandibular angel plasty. Masseter muscle and medial pterygoid muscle are inevitably injuried during the operation. With the postoperative recovery, muscles have adaptive changes which reduced compared with those before operation after their reattachment. Zygomatic plasty can cause temporal muscle atrophy;while the lateral pterygoid muscle is rarely involved, the cross sectional area had no statistical difference between the pre- and 10 days post-operative, and the cross sectional area increase at 3 months post-operatively may be due to a compensational enlargement.

Objective To investigate the function of SD rats Schwann cells on the growth and differentiation of adipose-derived stem cells(ADSCs) when they are co-cultured in Transwell culture system. Methods The ADSCs harvested from SD rats were divided into 3 groups. Group A: ADSCs and Schwann cells were cultured in Transwell indirect co-culture system. Group B: ADSCs were induced by β-BME and BHA. Group C: a contrast group. The morphology of ADSCs was observed and immunohistology was pedormed. Results ADSCs of group A and group B were partly differentiated to the cells which had long neurite,and had a positive result in the NF staining, but negative in the GFAP staining. Group A shows no great difference in neurite length compared with group B(P < 0.05), and no great difference in cell quantity compared with group C (P < 0.05). Conclusion Schwann cells of SD rat have a growth supportive and neuronal differentiation inducing effect on ADSCs.

Objective:To evaluate the precision of quantitative CT (QCT) in measuring fat content of goose liver and to explore the influence of tube voltage on liver fat measurement.Methods:From January to March 2017, 22 Landes geese were selected to establish fatty liver models with overfeeding. The QCT was performed under 2 different tube voltages, 80 and 120 kV. In addition to the voltage, the other scanning parameters were the same. Three ROI were placed in the centre part of the left lobe, upper and lower half of the right lobe on the 3D reconstructed images. The volume percentage of goose liver fat (Fat% QCT) was calculated according to the formula provided by Mindways. Immediately after the QCT examinations, each goose was dissected, and the whole liver was removed. Then samples were taken in the corresponding areas of the ROI by QCT. The fat (triglyceride) content of the samples was measured by the biochemical extraction method. The Spearman correlation tests were used to determine the correlation between the QCT measurements of 80 kV and 120 kV groups and the results of biochemical extraction method. The Wilcoxon signed-rank test was performed to compare Fat% QCT between 80 kV and 120 kV groups. Bland-Altman plots were used to assess agreement between the two groups′ measurements. Results:The Fat% QCT of both 80 kV and 120 kV group positively correlated highly with biochemical extraction ( r s=0.936, P<0.001, r s=0.927, P<0.001) respectively. No statistically significant difference of Fat% QCT was detected between 80 kV and 120 kV group ( Z=-0.141, P=0.888). Bland-Altman analysis showed a small difference of Fat% QCT between the 80 kV and 120 kV group, in which mean values were 0.20%. Conclusions:Using biochemical extracted triglyceride as the reference, under the conditions of low-dose 80 kV and standard 120 kV tube voltages, QCT measurement of fat content is accurate and reliable in goose liver.

Objective To compare the effectiveness and side-effect of different bowel preparations. Methods Three hundreds and twelve patients preparing for colonoscopy were randomly divided into four groups; oral mannitol group ( group A) , oral senna leaf group ( group B) , colon cleaning device group (group C) and combination of group B and C (group D). Under the colonoscopy, the endoscopist blindly scored the cleaning of each bowel segment as class 0 to 4 (0, fecal mass at rectosigmoid; 1, cleaning up to sigmoid; 2, cleaning up to descending colon; 3, cleaning up to transverse colon; 4, cleaning of entire colon ) and the degree of cleaning as optimal (Ⅰ) , acceptable ( Ⅱ ) or dissatisfied (Ⅲ). Results The cleaning rate (88. 6% ) of pan colon in group D was higher than that of group A ( 15. 4% , P

Objective To investigate the imaging findings with pathologic correlation in patients with acquired immune deficiency syndrome(AIDS).Methods Imaging findings,autopsy and pathological data were retrospectively analyzed in eight patients with AIDS.Routine CT scanning of different body parts was performed during their hospitalization.CT scanning was performed from the skull to the pelvis immediately following their death.After routine formalin fixing,7 cardevers were cross sectioned for autopsy in freezing state and 1 for gross autopsy.Tissues were obtained from each sections and organs for pathological examinations.Results The autopsy data showed parasitic infections(5 cases),bacterial infections (3 cases),fungal infections(2 cases),virus infections(2 cases),lymphoma(1 case)and cerebrovascular diseases(1 case)in eight patients with AIDS.The CT scanning demonstrated symmetrical ground glass liked shadows with pulmonary hilus as the center in 5 cases of pulmonary PCP infection; pulmonary patchy shadows,scattering distribution of nodular shadows,extensive military nodular shadows with even distribution and tuberculous pleurisy; cloudy shadows for 2 cases of fungi infection with multiple foci of chronic inflammation;pulmonary net-like parenchymal changes for 2 cases of pulmonary CMV infection;thickened intestinal wall and narrowed intestinal lumen for 1 case of intestinal tumor; low density shadows of brain tissue for 1 case of CMV encephalitis and MRI findings of high T_1 and high T_2 signals as well as MRA findings of broken vascular channels in liquefied areas of brain tissues; patchy low density areas inside a cyst of brain for one case of brain toxoplasmosis infection:multiple small patchy low density areas in cerebral basal ganglia for one case of brain cryptococcus infection.Conclusions In AIDS patients,infection and tumor may occur in various organs resulting in complex symptoms,which makes it more complicated and difficult to make accurate diagnosis.A correlative study of imaging findings and pathological manifestation of AIDS patients at autopsy could be helpful for clinical diagnosis.

[Objective]To assess the protective effects of Xianlinggubao on articular cartilage and subchondral bone in experimental osteoarthritis induced by anterior cruciate ligament transaction (ACLT)in rabbits. [Methods]Thirty healthy Japanese white rabbits were divided randomly into three groups:sham group,ACLT+XLGB group and ACLT+ NS group. Rabbits in ACLT+XLGB group and ACLT+NS group received anterior cruciate ligament transection(ACLT)on the right knee. Rabbits in sham group received untreatment as control. ACLT+XLGB group received a daily administration of XLGB at a dose of 125 mg/kg of body weight for 6 weeks.In contrast,ACLT+NS group received saline at the same dose. All rabbits were sacrificed at 6 weeks after operation. The right femora were removed,measured for bone mineral density (BMD),and then were observed for the macro-pathologic changes with HE staining and graded by Mankin's scale. Expression levels of BMP-2 and MMP-13 were detected by immunostaining. The subchondral bone of right tibial plateau was cut and stained for the measurement of bone histomorphometry.[Results](1)The Mankin's score in ACLT+ XLGB group was significantly lower than that in ACLT+ NS group (P

Objective:To explore the relationship among procrastination behavior,meta -cognitive and emotion of university students.Methods:A total of 468 undergraduates from 4 universities were surveyed by GPS,PANAS and MCQ-30.Results:①The undergraduates from liberal arts colleges reported more procrastination behavior than those from science colleges.② Cognitive confidence,positive beliefs,uncontrollability/danger,tendency to control thoughts,and negative emotion positively correlated to procrastination behavior;cognitive self-consciousness and positively emotion negatively correlated to procrastination behavior.③ Cognitive confidence,uncontrollability/danger and negative emotion could positively predict procrastination behavior.④Negative emotion mediated the relationship between uncontrollability/danger and procrastination behavior.Conclusion:Uncontrollability and danger are a significant predicator of procrastination behavior,and negative emotion has a significant mediation effect on the relationship between uncontrollability/danger and procrastination behavior.
