Objective To explore the spatio-temporal regularity of cerebral edema in the early stage of severe burn (50% TBSA Grade Ⅲ) with four-dimensional (4D) mathematic model. Methods Twenty-six dogs were randomly divided into control group and 6, 12, 18 and 24 hours post-burn groups. The dogs in the postburn groups suffered severe burn of 50% TBSA GradeⅢ. Six hours after burn, 50 g/L glucose was injected according to Parkland formula. MRI manifestation, histopathological changes, brain water content and intracranial pressure were observed in each group. A 4D mathematic model was established based on the results of MRI scanning. Results Two turning points ( 6 and 18 hours postburn) and three phases of pathologic changes were displayed by 4D mathematic model of cerebral edema in the early stage of severe burn. The first phase (6 hours postburn) was in the subclinical period,when an effective treatment should be taken as quickly as possible so as to prevent deterioration of postburn cerebral edema. The second phase ( 6-18 hours postburn) was in the apostatic period with pathologic characteristic of vasogenic and cytotoxic brain edema. The third stage (18-24 hours postburn) was the critical period of cerebral edema. Intracerebral pressure (ICP) increased rapidly due to limitation of cranial cavity, when cerebral hernia easily happened. Conclusions The 4D model indicates that there is a feature of type S curve in the pathologic process of cerebral edema in the early stage after severe burn.

Objective To observe the growth and differentiation of the cultured mouse bone marrow stromal cells in vitro into neural like cells. Methods Bone marrow stromal cells (BMSCs) isolated from mice were cultured according to the routine method, and induced to differentiate by basic fibroblast growth factor b (bFGF), retinoic acid (RA), nerve growth factor (NGF), and dimethylsulfoxide (DMSO). Expressions of neural microfilament protein (NF 200), glial fibrillary acidic protein (GFAP), and fibronectin at 72 h after inductin were determined by immunoflurenscence and immunocytochemicalmethod. Results At 72 h after inductin, neural like changes were found in BMSCs. Immunohistochemical stain showed that 60% BMSCs differentiated into NF 200 positive cells, and about 50% BMSCs into GFAP positive cells. Fibronectin expression was significantly lower as compared with that in the control group. Conclusion Combined action of RA, bFGF, NGF, and DMSO can induce BMSCs to differentiate into neural like cells in vitro .

ObjectiveTo examine the relationship between belief in a just world of college students and prosocial tendencies.Methods400 college students were examined by using the belief in a just of Chinese versions ( BJW ) and the prosocial tendencies scales.Results①There was a marginally significant difference on college student's general belief in a just world and personal belief in a just world among different grades ( F=3.90,F=3.05,P ＜ 0.05 ).②The personal belief in a just world and general belief in a just world was significantly posilively correlated with the prosocial tendencies of college students ( r =0.25,r =0.24,P ＜ 0.01 ).③Significant differences existed between the high-scoriug,the middle group and the low-scoring BJW group in prosocial tendencies and its sub-dimensions ( F =3.36 ～ 12.87,P ＜ 0.05,P ＜ 0.01 ),expect the openness dimension of prosocial tendencies( F =1.71,P ＞ 0.05 ).The scores of those three groups on prosocial tendencies ( (3.74 ± 0.43 ),( 3.57 ± 0.42),( 3.44 ± 0.43 ) ) and its sub-dimensions shows a decreasing trend from high to low.④Layer multivariate linear regression analysis showed that general belief in a just world were significant predictors of the prosocial tendencies( β =0.18,P＜ 0.01 ).ConclusionsThe intensity of belief in a just world has a certain impact on the prosocial tendencies of college students.

Phased national medical licensing examination requires clinical students to have the ability to apply basic medical knowledge to solve comprehensive clinical problems. But the traditional teaching patterns of Medical Microbiology experiments can no longer meet requirements of actual education effect. In order to accommodate new situation, we have integrated medical licensing examination with microbiology experimental teaching syllabus and contents. We have also comprehensively applied a variety of teaching methods and curriculum formative assessment in class. These reforming methods have efficiently improved classroom teaching effect and greatly inspired the enthusiasm of students, and effectively improved early clinical thinking ability and innovation ability of students.

BACKGROUND: Foreign and domestic scholars have made some studies on local anatomy and imageology of osseous pterygopalatine fossa, but studies on anatomy of section of osseous pterygopalatine fossa are few.OBJECTIVE: To measure hole-hole distance and aperture of pterygopalatine fossa from adult cranial bone at coronary and horizontal planes, and to observe the morphology of pterygopalatine fossa at corresponding sections.DESIGN: Repeated measurement design.SETTING: Scientific Research Office, Chengdu Medical College.MATERIALS: This experiment was carried out in the Laboratory for Local Anatomy, Department of Human Anatomy,Chengdu Medical College from March to November 2006. Sixty sides of complete dry cranial bone samples from 30 Chinese adult cases, who were of either gender and regardless of age, were involved in this study.METHODS: Bilateral pterygopalatine fossa of 30 dry cranial bone samples (60 sides) were sliced, 15 for slicing at coronary plane, and 15 for slicing at horizontal plane. Morphology of pterygopalatine fossa at the corresponding layers was observed, and related hole-hole distance and aperture were measured. Outcome was performed statistical analysis.MAIN OUTCOME MEASURES: Measurement at coronary plane: [1]orbit-rotundum distance (distance from the lowest point of inferior orbotal fissure to the center of rotundum); ② rotundum- pterygoid canal distance Ⅰ (vertical distance from the center of rotundum to the center of pterygoid canal); ③ rotundum- pterygoid canal distance Ⅱ (Distance from the area where rotundum appeared to the area where pterygoid canal appeared). Measurement at horizontal plane: [1]anterior-posterior dimension ( the largest distance between anterior and posterior walls which paralleled to perpendicular plate of palatine bone in each layer); ② lateral dimension (distance from midpoint of perpendicular plate of palatine bone to midpoint of line, which was between outermost sphenoidal process in the anterior wall of pterygopalatine fossa and foremost evagination in the posterior wall of pterygopalatine fossa). Morphology of pterygopalatine fossa in each layer was observed at coronary and horizontal planes, separately.RESULTS: ①At the coronary plane, the 1st to 6th layers of bilateral pterygopalatine fossa presented with inclined inverted trapezoid (70%, 21 sides), and inclined quadrilateral (30%, 9 sides), and the 7th to 10th layers of bilateral pterygopalatine fossa presented with canal-shape (100%). Themean value of right orbit-rotundum distance was (5.0±2.7) mm, andthat of left orbit-rotundum distance was (5.3±2.1) mm; The mean value of right rotundum- pterygoid canal distance Ⅰ was (6.4±3.9) mm, and that of left rotundum- pterygoid canal distance Ⅰ was (6.1±4.3) mm; The mean value of right rotundum- pterygoid canal distance Ⅱ was (7.3±2.6) mm, and that of left rotundum- pterygoid canal distance Ⅱ was (7.5±2.1) mm. ② At horizontal plane: The anterior and posterior walls of the 1st and 2nd layers of bilateral pterygopalatine fossa mainly presented with double curves with palinal convex surfaces (80%, 24 sides); the 3rd and 4th layers mainly presented with opposing convex surfaces (66.7%, 20 sides); The 5th to 6th layers mainly presented with canal shape (60%, 18 sides);And the 7th to 10th layers presented with canal shape (100%). At horizontal plane, for the pterygopalatine fossa in the 1st to 6th layers, its lateral dimension was larger than its anteroposterior dimension, and for the pterygopalatine fossa in the 7th to 10th layers, its lateral dimension was equal to its anteroposterior dimension. There were no significant differences of aperture in each layer of pterygopalatine fossa between bilateral samples (P＞ 0.05).CONCLUSION: Anatomical studies on the section of osseous pterygopalatine fossa retrieve the limitation in local anatomy,and provide reliable anatomical evidence for imageology of pterygopalatine fossa and related surgical operation.

Objective To evalute effects of low calcium concentration dialysate on blood pressure,ionized calcium and serum endothelin-1 of uremic patient with hypertension during hemodialysis.Methods 60 uremic patients with hypertension during hemodialysis in the Shengjing Hospital of China Medical University were dialysated with different calcium concentration(1.75 mmol/L followed by 1.25 mmol/L).TO measurearterial blood pressure,ionized calcium and serum endothelin-1 before and after each dialysis session.Results The post-dialysis blood pressure,ionized calcium and serum endothelin-1 level of uremic patients using DCa1.75 with hypertension during hemodialysis were increased significantly than those of pre-dialysis and post-dialysis with DCa1.25(P

Objective To investigate the effects of zinc gluconate combined with Danshen injection on the plasma lipid level following exposure to noise in rats. Methods Fifty female SD rats were randomly divided into a control group, a noise exposure group (model group), a zinc gluconate + noise exposure group (zinc gluconate group), a Danshen injection+noise exposure group (Danshen injection group) and a zinc gluconate+Danshen injection+noise exposure group (combination group), 10 rats in each group. The zinc gluconate group received intragastric administration of zinc gluconate 8-10 mg/(kg?d), the Danshen injection group received intraperitoneal injection of Danshen injection 6 mg/(kg?d), the combination group received intragastric administration of zinc gluconate 8-10 mg/(kg?d) and intraperitoneal injection of Danshen injection 6 mg/(kg?d). On the day 10, except in the control group, the rats in the rest of the groups were continuously exposed to high frequency steady noise for 7 days (4 000 Hz, 95 dB, 3 h/d). The serum levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. Results The serum levels of TC (1.88 ± 0.17 mmol/L vs. 1.55 ±0.09 mmol/L), TG (1.45 ± 0.38 mmol/L vs. 1.01 ± 0.27 mmol/L), LDL-C (0.29 ± 0.04 mmol/L vs. 0.23 ± 0.03 mmol/L) in the model group were significantly lower than those in the control group (P<0.01 or P<0.05), while the serum HDL-C level in the model group were significantly lower than that in the control group (0.55 ± 0.08 mmol/L vs. 0.62 ±0.06 mmol/L;P<0.01). The serum TC level in the zinc gluconate group was significantly lower than that in the model group (1.71 ± 0.11 mmol/L vs.1.88 ± 0.17 mmol/L;P<0.05). The serum levels of TC (1.73 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L) and LDL-C (0.25 ± 0.03 mmol/L vs. 0.29 ± 0.04 mmol/L) in the Danshen injection group were significantly lower than those in the model group(all P<0.05). The serum levels of TC (1.57 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L), TG (0.84 ±0.40 mmol/L vs. 1.45 ± 0.38 mmol/L) and LDL-C (0.24 ± 0.05 mmol/L vs. 0.29 ± 0.04 mmol/L) in the combination group were significantly lower than those in the model group (P<0.01 or P<0.05), and the serum HDL-C level (0.61 ± 0.07 mmol/L vs. 0.55 ± 0.08 mmol/L) in the combination group was significantly higher than that in the model group (P<0.05). Conclusions Noise exposure may induce dyslipidemias in rats. Zinc gluconate and Danshen injection can regulate the plasma lipid level following exposure to noise in rats, and combination of zinc gluconate and Danshen injection may be superior to zinc gluconate or Danshen injection alone.
