The concept of humanistic education is based on the concern of human beings and their abilities of development. Thus,it is an educational concept to optimize the teaching modules.It stresses the point that education must regard the develop- ment of human beings as the main line and human beings should be emphasized in education from the very beginning to the end. Case-Teaching Method which takes the students as the main part fully manifests the concept of humanistic education,in which all teaching activities and the processes closely revolve the students in order to train them to carry on their studies and to solve the problems independently.

OBJECTIVETo explore the effect of Shenxiong Huayu Capsule (SHC) on the cerebral ischemia-reperfusion (IR) injury and the expression of growth associated protein 43 (GAP43) after total cerebral IR in the hippocampal CA1 region of rats.
METHODSTotally 100 male adult SD rats were randomly divided into five groups, i.e., the control group, the model group, the group A (by taking SHC once daily), the group B (by taking SHC twice daily), and the group C (by taking SHC thrice daily), 20 in each group. The total IR model was prepared by improved Pulsinelli's 4-vessel occlusion method. Morphological changes of the hippocampal CA1 region were observed by HE staining at day 1, 3, 7, and 14. The expression of GAP43 in the hippocampal CA1 region was detected using immunohistochemical assay at day 1, 3, 7, and 14. Meanwhile, the behavioral score was determined. The expression of GAP43 in the hippocampal CA1 region was detected using Western blot at day 14.
RESULTSCompared with the control group, the expression of GAP43 increased in the model group, the behavioral score was elevated, degenerated neurons increased, and survival neurons decreased in the model group (all P < 0.05). Compared with the model group, the expression of GAP-43 increased (with the most significant difference seen in the group C, P < 0.01), the behavioral score significantly decreased, degenerated neurons decreased, and survival neurons increased in each HSC group (all P < 0.05). Survival neurons obviously increased at day 14, of which, most number of survival neurons and highest contents of GAP43 protein could be seen in the group C, showing statistical difference when compared with those of the group A and the group B (P < 0.01).
CONCLUSIONSHC had protective effect on total cerebral IR in the hippocampal CA1, which might be associated with increased expression of GAP43.

7. Medical protection patterns in preventing heat stroke during 5-km armed field examination in summer
Academic Journal of Second Military Medical University 2017;38(12):1577-1580
Objective To discuss the role of medical protection patterns in preventing exertional heat stroke during 5-km armed field examination in summer. Methods We analyzed the original data collected from 501 soldiers who completed the 5-km armed field examination in the summer of 2016. The soldiers received medical protection during examination and were divided into fully-equipped group (loading 9-12 kg, n=270) and non-equipped group (n=231). The temperatures of the soldiers were detected before and after examination, and the temperature changes and the number of soldiers with hyperthermia after examination were compared between the two groups. Results A total of 501 soldiers took part in the 5-km armed field examination, and 51 (10.18%) soldiers were found with fever (temperature > 37 °C), with a highest temperature of 40.9 °C. Nine were put on a temporary stay in the field medical facility. Among them, four were observed because of the temperature maintaining at 38 °C for 15 min, and their temperatures dropped to below 37 C after cooling fluid infusion for 50-120 min; four were observed because of chest tightness, suffocation, and abdominal pain; one was observed because of faint; the latter five cases were improved without other treatments. No case was evacuated to the hospital. There was no significant difference in temperature between the fully-equipped and non-equipped groups before the examination, while the temperature in the fully-equipped group was significantly higher than that in the non-equipped group after the examination ([36.64±0.67] °C vs [36.48±0.38] °C, P<0.05). The number of soldiers with hyperthermia in the fully-equipped group was significantly more than that in the non-equipped group after the examination (16.67%[45/270] vs 2.60% [6/231], P<0.05). Conclusion The 5-km armed field examination in summer can elevate temperatures of the soldiers and has risk of inducing heat stroke. Establishing a targeted medical protection pattern during the examination may help to timely detect fever in the soldiers and give prompt treatment, so as to effectively prevent heat stroke.

Objective To investigate the effect of long-term high-fat diet on insulin resistance and the morphology and function of islets in rats and the relationship between them.Methods Thirty normal male Wistar rats (8 weeks old) were divided into two groups and fed either with normal chow (NC,n=15),or high-caloric and high-fat diet (HF,n=15).Insulin resistance was assessed by euglycemic hyperinsulinemic clamp technique. The insulin secretory function of islets was evaluated by intravenous insulin releasing test.Morphological and quantitative analysis of pancreatic tissues was performed by double-label insulin and glucagon immunohistochemistry.Proinsulin mRNA was detected by RT-PCR.Results The glucose infusion rate (GIR) in HF rats was significandy lower than that in NC rats [(5.83?0.79)mg?kg~(-1)?min~(-1) vs (7.60?1.29)mg?kg~(-1)?min~(-1),P<0.05].Immunohistochemistry showed that HF rats had larger islet size [(15168?1327)?m~2 vs (6264?1840)?m~2,P<0.01] and significantly reduced insulin relative concentration of?cells[(-5.15?0.03) vs (-4.81?0.17),P<0.01],as compared with NC rats.The islet relative?cell volume was decreased signifieandy (P<0.01),whereas the relative?cell volume was increased (P<0.01).So the ratio of?to?were lower in HF [(4.68?1.01) vs (11.84?3.82),P<0.05].The peak of insulin secretion in intravenous insulin releasing test in HF was at 10 min,whereas that in NC rats was at 5 min.AUC (area under curve) 10-60 rain of insulin in HF was higher than that in NC rats [(152.51?34.53)mIU?L~(-1)?min~(-1) vs (86.40?21.21) mIU?L~(-1)?min~(-1),P<0.01].There was no difference in proinsulin mRNA levels between two groups. Conclusion Long-term high-caloric and high-fat diet results in early impairment of islet morphology and function, as well as significant insulin resistance,suggesting that the compensation ability of islets has already been impaired in the early course of type 2 diabetes mellitus.

Objective To study the expression and clinical significance of ezrin in breast carcinoma. Methods Immunohistuchemieal staining(S-P) was used to detect the expression of ezrin in 63 cases of breast car-cinoma samples. Results Among these 63 samples,the total expression rates of ezrin were 55.56% (35/63). With the increasing of axillary lymph nodes metastasis and clinical staging,the rates of expressing of ezrin elevated (P<0.05),which was remarkably lower in patients whose disease-free survival(DFS) was > 5 years,or those whose DFS≤5 years or died within five years(P<0.05) ,but the expression of ezrin was not correlated with tumor size,age and menopausal status (P>0.05). Conclusion The expression of ezrin may contribute to prognostic e-valuation for breast carcinoma.

To study the influence of stir-baked with sand on active ingredients, diarrhea and hepatoprotection of Herpetospermum caudigerum, the contents of herperione and herpetin in H. caudigerum before and after stir-baking with sand were analyzed by HPLC. The effect of stir-baked with sand on diarrhea of H. caudigerum TL was evaluated using the mean stool rate (MSR) and mean diarrheal index ( MDI) and the influence of stir-baked with sand on hepatoprotective effect of H. caudigerum TL was examined using a mouse model of CCl4-induced liver injury based on the analysis of serum ALT and AST activities. The results of HPLC analysis showed the content of herperione in H. caudigerum after stir-baking with sand decreased by 40.9% (P < 0.01) and the content of herpetin had no change. Pharmacodynamic results showed that the MSR and MDI of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were significantly lower than that of high-dose and middle-dose group of H. caudigerum TL without stir-baking with sand; The high-dose and middle-dose of H. caudigerum TL with/without stir-baking with sand significantly alleviated liver injury as indicated by the decreased levels of serum ALT and AST, but the ALT and AST levels of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were higher than that of H. caudigerum TL without stir-baking with sand. The results revealed that the stir-baking with sand could effectively relieve diarrhea effect of H. caudigerum TL, while it also reduces the hepatoprotection of H. caudigerum TL.
