Objective To discuss effective methods for treating hypertensive intracerebral hemorrhage at the different sites. Methods Different operative methods were adopted in 85 cases of hypertensive intracerebral hemorrhage at the different sites from January 2001 to August 2003 in this hospital. Small fenestration and hematoma clearance under local intensify anesthesia was conducted in 40 cases of hemorrhage under the cortex or in the lateral area of the basal ganglia and without brain hernia; small incision trepanation with suction and drainage of hemorrhage under local intensify anesthesia was used in 26 cases of hemorrhage in the medial area of the basal ganglia without brain hernia; craniotomy and hematoma clearance under general anesthesia was adopted in 11 cases of preoperative brain hernia and 6 cases of cerebellar hemispheric hemorrhage; lateral ventricle external drainage was adopted in 2 cases of brain stem hemorrhage involving into the fourth ventricle and also in these cases with ventricle involved. Results The overall mortality rate was 12 9% (11/85). There were no deaths in cases of hemorrhage without brain hernia,under the cortex, in the cerebellum, in the brain stem or in the lateral area of the basal ganglia.The mortality was 29 0% (9/31) in cases of hemorrhage in the medial area of the basal ganglia and 45 5% (5/11) in cases of preoperative brain hernia, respectively. Conclusions Small fenestration and hematoma clearance under local anesthesia is effective for hemorrhage under the cortex or in the lateral area of the basal ganglia and without brain hernia. Provided surgical treatment is early and adequate, the prognosis of cerebellar hemorrhage is excellent. Small incision trepanation with suction and drainage under local anesthesia exerts no appreciable effect on hemorrhage in the medial area of the basal ganglia.

Objective To evaluate the performance of virtual touch tissue quantification imaging (VTQ) for differential diagnosing in uterine hysteromyoma and adenomyoma. Methods Blood flow parameters and SWV (shear wave velocities) from 42 regular hysteromyomas,14 abnormal hysteromyomas and 25 uterine adenomyomas were compared and analyzed through color Doppler. Results The SWV of regular hysteromyomas was on average of (2.72 ± 0.31) m/s;that of abnormal hysteromyomas (1.88 ± 0.25) m/s;while the SWV of uterine adenomyomas was on average of 1.91 ± 0.27 m/s. The mean SWV in regular hysteromyomas group was significantly higher than that in abnormal hysteromyomas group and uterine adenomyomas group (P < 0.05). There was no significant difference of SWV between abnormal hysteromyomas group and uterine adenomyomas group (P > 0.05).The resistance index and SWV of uterine hysteromyomas and adenomyomas had positive correlation (r = 0.753,0.544,0.506,P < 0.05). Conclusion VTQ can quantify the stiffiness of uterine hysteromyoma and adenomyoma.

Objective To observe and classify the structure of the circle of Willis by using magnetic resonance angiographic(MRA)method. Methods A total of 2104 MRA head images from October 2013 to May 2015 in Shenyang Weikang Hospital was retrospective analyzed ,and the structure was classified by anterior circle or posterior circle according to the actual situation of the cerebral basilar artery. Results According to the origin of anterior cerebral artery and whether there was anterior communicating artery or not ,anterior circle was classified into three types:type Ⅰ,type Ⅱ and type Ⅲ. Type Ⅱ was classified into two subtypes,namely,type ⅡR and type ⅡL. Posterior circle,on the basis of whether there was posterior communicating artery or not,was classified into three types,which were type Ⅰ,type Ⅱ and type Ⅲ. According to the origin of posterior cerebral artery,type Ⅰ was classified into four subtypes,including type ⅠB,type ⅠC,type ⅠRC and type ⅠLC;type Ⅱ was classified into eight subtypes,including type ⅡBR,type ⅡBL,type ⅡCR,type ⅡCL,type ⅡRCR,type ⅡRCL,type ⅡLCR and type ⅡLCL;type Ⅲ was classified into four subtypes,including type ⅢB,type ⅢC,type ⅢRC,type ⅢLC. Conclusion There is a correlation among the different types of cerebral basi-lar artery,and each type of artery has their own sources of blood supply and the traits of communication compensation. When the anterior circle and posterior circle were both type Ⅲ,the complete ring structure of cerebral basilar artery,namely the circle of Willis,was formed. The existing rate of the circle of Willis was about 10.7%. Understanding of the differences among the individual types of arteries has great significance to the prevention and treatment of the cerebrovascular disease.

Objective to analyze the basic situation of university and college teachers′psychological empowerment,and investigate the effect of perceived organizational support,organizational identification,supervisory commitment on psychological empowerment. Methods the instruments which were used include perceived organizational support questionnaire(POS),organizational identification questionnaire(OIQ),supervisory com-mitment scale(SCS)and psychological empowerment scale(PES). A total number of 1 500 teachers were recruited conveniently from 6 university and colleges. Results the average score of psychological empowerment was 60.09±14.21. Positive correlation was found among perceived organiza-tional support,organizational identification,supervisory commitment and psychological empowerment(P < 0.05). Perceived organizational support, organizational identification and supervisory commitment explained 86.5% of variance of psychological empowerment. Conclusion Overall level of university and college teachers′psychological empowerment is in moderate or above degree. Perceived organizational support,organizational identifi-cation,and supervisory commitment can predict a deep level of psychological empowerment.

Objective To study the protective effect of fluvastatin on cardiac remodeling and cardiac function, and to investigate its effect on Von Willebrand factor (VWF). Methods The rat model of cardiac heart failure (CHF) was in-duced by isoproterenol injection (170 mg/kg) via subcutaneous. Eighteen model rats were randomly divided into fluvastatin (20 mg ·kg-1·d-1) group, placebo group and control group. Rats were treated with normal saline in placebo group and control group. After 6-week treatment, the structure and function of hearts were measured by echocardiography in three groups. The ventricular weight index, the serum levels of VWF and B-type natriuretic peptide (BNP) were measured by ELISA assay. The levels of VWF mRNA in cardiac muscle were measured by RT-PCR. Results Compared with control group, the val-ues of left ventricular end-diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were significantly increased in placebo group and fluvastatin group, while values of left ventricular ejection fraction (LVEF) and left ventricular ejection fraction shortening (LVFS) were significantly decreased (P＜0.05). The values of left ventricular wet weight/body weight (LVRW) and right ventricular wet weight/body weight (RVRW) were increased in placebo group and fluvastatin group. The expression of VWF mRNA in cardiac tissues was enhanced significantly (P＜0.01). Compared with placebo group, the values of LVEDD, LVRW and RVRW were significantly decreased in fluvastatin group. The expression of VWF mRNA in cardiac tissues was significantly decreased (P＜0.01), and the values of LVEF and LVFS were significant increased in fluvas-tatin group (P＜0.05). The level of VWF was positively corrected with BNP(r=0.996). Conclusion Fluvastatin could im-prove the cardiac function and cardiac remodeling, which may be by reducing the level of VWF and improving endothelial function.
