Objective: To find out the features of family ecosystems of high school students at different levels of tolerance of perceived learning stress. Methods:Using several questionnaires such as CBCL, EMBU etc to collect data on three main family sub-ecosystems: parental subsystem, family social environmental subsystem and children's subsystem. Results: Of 170 subjects, there were 130 who reported they could perceive learning stress. Of the 130 students, there were 30 with mental or behavioral problems (low tolerance group), while the other 100, a large portion, functioning very well without mental or behavioral problems (high tolerance group). Compared with low tolerance group, high tolerance group had lower scores in father's punishment (17.9?5.1/20.5?4.6, t=-2.51, P

Objective To investigate the imaging diagnostic value of the early avascular necrosis of the femoral head(ANFH) in adult.Methods There were 25 cases (34 hips) with early ANFH diagnosed by imaging and clinical data.Radiography,CT and MRI findings of ANFH were analysed comparatively.Results In the 34 ANFH included stage Ⅰ 13 hips,stage Ⅱ 21 hips.The diagnostic accurary was 32.4% for X-ray,61.8% for CT and 100% for MRI.Conclusion MRI is better than the other technique in early finding the lesions of ANFH,and the diagnostic sensitivity and accuracy of MRI are higher than that of CT and X-ray.

Objective To explore a new surgical method for the treatment of refractory fistula after breast augmentation and to improve patients healing efficiently.Methods This paper had collected two groups,a total of 178 cases of injected breast augmentation,who had shown the polyacrylamide hydrogel(PAAG)mixture shift,and caused abdominal fistula.Among them,89 cases further adopt new design in the treatment of fistula by using breast muscle membrane tissue flap and improve the effect of fistula treatment after the removal of fistula.And the other 89 cases were token the pure clean the cavity away caused by the abnormal material shift into the chest and abdominal wall.Results It was observed that PAAG widely distributed in the chest and abdominal wall and formatted the fistula connected mammary gland,axillary,chest abdominal wall.The area of lesions lacuna shrink by 80％ for the group used tissue flap after 2 weeks,but those not with tissue flap shrink by 45％(P＜0.01).At 4th week,all the patients of flap group achieved tissue healed,while the completely heal ratio of control group was only 73％.Compared two groups of healing rate,the group with tissue flap was obviously better than ones only with surgical method.Conclusion It suggests that main reasons for the liquidity bag and huge cavity are PAAG mixture shift into thoracic and abdominal wall and formed chronic fistula and connected the chest and abdominal wall.Local muscle membrane tissue flap can obviously promote the chest and abdominal wall fistula healing.

AIM: To evaluate the effects of compound salivia miltorrhiza injection on an experimental model of kidney thrombus induced by lipopolysaccharide(LPS).METHODS: The model of microvascular thrombosis in the rabbits' kidney was performed by the method of Hermida,which was induced by infusing LPS.Treatments were begun simultaneously with LPS infusion,through the contralateral marginal ear vein.Six different groups were established: NS 10(ml?h~(-1)) was infused as the negative control group,compound salivia miltorrhiza injection was infused with the dosage of(0.1)(Low-dose),(0.2)(medium-dose),and 0.4(high-dose)(ml?kg~(-1)?h~(-1)),heparin 600,000(IU?kg~(-1)?h~(-1)) as positive control group.The further rabbits, which were given neither LPS nor compound salivia miltorrhiza injection,were infused with saline solution through both marginal ear veins.The measurement of fibrinogen concentrations and platelet counts were used to assess the degradation of microvascular thrombosis.Kinney sections were examined for the presence of fibrin microthrombi.RESULTS: Compound salivia miltorrhiza injection was infused with the dosage of(0.1)(Low-dose),(0.2)(medium-dose),and(0.4)(high-dose)(ml?kg~(-1)?h~(-1)),and the fibrinogen concentrations and blood platelet counts were improved,and the fibrin deposition was degraded.CONCLUSION: Compound salivia miltorrhiza injection can inhibit effectively LPS-induced renal microvascular thrombosis.

Objective To explore the difference of the risk factors among the rural residents with hypertension with different social economic levels.Methods Risk factors survey were conducted in 469 new cases with hypertension(aged over 35) with different economic-social levels in Jizhou city,Hebei province using self-made questionnaire,2799 people(aged over 35) as the controls.The results were analyzed with Logistic regression analysis.Results OR of the risk factors in higher economic level group were:family history of hypertension(2.863),body mass index(BMI,1.286),preserved foods(1.263),the amount of eggs taken daily(1.200) and the ages of the patients(1.052).The OR of risk factors in lower economic levels' group were:family history of hypertension(3.990),smoking(1.767),the amount of eggs taken daily(1.753),drinking(1.728),education background(1.532),sex(1.448),daily amount of meat intake(1.276),BMI(1.205) and the age of the patients(1.068).The higher annual income of the family and the amount of fresh fruits intake daily were the protective factors of hypertension with the OR were 0.708 and 0.788 respectively.Conclusion The results show that the patients at different economic levels have different risk factors of hypertension.

Objective To report the clinical effects of microsurgery in treatment of infected extremities after blood vessel prosthesis were transplanted.Methods From Jan.1998 to Dec.2008,8 cases of major vascular injuries in extremities were blood-supplied by cross bridge vascular anastomosis from uninjured extremities,including 4 cases of femoral artery and vein,2 cases of popliteal artery and vein,and 2 cases of brachial artery and vein. Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

Objective To investigate the interventional effect of sulforaphane (SFN) on brain Aβ deposition and oxidative stress in Alzheimer's disease model mice.Methods Eight-week old C57BL/6J mice were randomly divided into three groups (n =10,each).Mice in two groups (intervention and model)were administered by drinking water containing 0.4g aluminum /100ml water and subcutaneous injection with 200mg/kg D-galactose every other day,added with 25mg/kg SFN to the intervention group or with equivalent double-distilled water to model group by a single oral gavage daily.And equivalent vehicle were given to the control mice.After 90 days,the aluminum levels in blood,brain Aβ depositions,and indices of oxidative stress in cerebral cortex were investigated.Results Blood aluminum level was higher in the AD model and SFN intervention groups than in controls(P＜0.01),and was lower in SFN intervention group than in AD model(P＜0.01).As compared to controls,the AD model showed that brain Aβ deposition was significantly increased,GPX activity was decreased and carbonyl level was remarkable increased(P＜0.05).There were no significant differences between intervention and control group in brain Aβ deposition,GPX activity and carbonyl contents (P＞0.05).Brain Aβ deposition was lower in intervention than in model group(P＜0.05).There was no significantly differences in brain SOD activity and total hydrosulfuryl content among three groups(P＞0.05).Conclusions Sulforaphane can reduce the aluminum level in blood,attenuate Aβ deposition,and regulate the oxidative stress in cerebral cortex in AD model mice.
