Objective To evaluate the clinical efficacy of 3D DCE MRA(three dimensional dynamic contrast-enhanced MR angiography)in patients of preoperation of liver transplantion.Methods 8 cases of potential liver transplant recipients suffering from severe liver disease underwent MRI and 3D DCE MRA, accessed the images synthetically. All of them had DUS examination, 4 cases received liver transplantation successfully.Results Satisfactory angiography images were obtained in all cases, the grade Ⅱ～Ⅲ branches of the hepatic artery, the grade Ⅱ～Ⅴ branches of the portal vein and gradeⅡ branches of the hepatic vein could clearly be visualized. Gastric-oesophageal varices were found in 3 cases of cirrhosis, compression and displacment of hepatic artery and portal vein were shown in one case of polycystic liver.Conclusion 3D DCE MRA is an efficiency, noninvasive technique, it offers great help in evaluating pre-operative vasculature of liver transplantation.

Objective To study the effect of preoperative blood pressure control on postoperative cardiovascular events in patients with hypertension and gastrointestinal surgery. Methods A total of 238 hypertensive patients who underwent gastrointestinal surgery were selected and divided into control group (n =118)and non-control group (n =120)according to thehypotensor treatment.During the operation,the same anesthetic regimen was used.The use of vasoactive drugs was recorded during anesthesia.Bladder chalone C (Cys C)and cardiac troponin T (cTnT)were de-tected in blood before and after the operation,and so were N-terminal B type natriuretic peptide (NT-proBNP)level on the 1st and 5th day after the operation.The postoperative hospitalization time,fol-low-up of cardiovascular events 28 and 90 days after discharge were recorded.Results Compared with the non-control group,the total dosage of ephedrine in the control group was significantly re-duced [(3.41±1.04)mg vs (7.46 ± 3.29)mg,P <0.05 ],total dose of phenylephrinewas signifi-cantly reduced [(0.17±0.10)mg vs (0.46 ±0.16)mg,P <0.05],postoperative hospital stay was significantly shorter [(5.92±1.15)d vs (9.65±1.61)d,P <0.05],NT-proBNP level in the control group on the 1st day after the operation [(108.00 ± 47.11 )pg/L vs (250.38 ± 62.92 )pg/L,P <0.01]and 5 days after the operation [(62.07 ±25.31)pg/L vs (199.02 ± 60.32)pg/L,P <0.01 ] was obviously reduced.There was no statistical difference in Cys C andcTnT between the two group-safter operation.The incidence of cardiovascular adverse events in the control group was significantly lower than that in the non-control group (28 d:13.6% vs 62.7%,90 d:23.3% vs 23.3%,P <0.05).Conclusion Strict control of preoperative blood pressure control in patients with hypertension can significantly reduce the incidence of cardiovascular events.

Objective To investigate quality of life and its influencing factors among elderly women with urinary incontinence(UI) living at nursing homes in Beijing. Method A randomized method was used to select six districts in Beijing. All the nursing homes in these 6 districts were included in our study,642 eligible elderly women participated in the survey. Quality of life of 244 women who were identified with different type UI were assessed. Bivariate analysis and multiple analysis were performed. Results The average score of quality of life was 8.5 ± 6.6. Scores of social embarrassment, activity & limiting behavior, psychosocial impacts were 1.8 ± 1.4,4.0 ± 3.5 and 3.3 ± 2.7 respectively. In bivariate analysis, significant differences were found by type of UI, severity of UI,course of UI, health condition, income level and self-care ability. In multiple analysis after adjustment of other variables, UI course≥5 years and inability to take care of herself were risk factors of quality of life.Conclusion Quality of life of elderly women with UI is poor, specific nursing and treatment should be conducted.

Objective To evaluate prevalence and risk factors of urinary incontinence(UI)among aged women living at nursing homes in Beijing,and provide references of relative health strategy.Methods Totally 642 women aged 60 years and over were randomly selected at nursing homes from 6 districts in Beijing.A questionnaire survey was conducted using International Consultationon Incontinence Questionnaire Female Lower Urinary Tract Symptoms Module (ICIQFLUTS) recommended by International Consultation on Incontinence (ICI).Results The prevalence rate of UI was 38.0％ (244/642) among whom 38.5％ (94/244) of participants knew their health conditions,7.8％ (19/244) visited hospital and 6.6％ (16/244) received medical or operational treatment.The proportions of respiratory disease ( 27.0 ％ vs.14.6％),digestive disease (23.4％vs.15.3％),urological disease(24.6％vs.8.5％),cardio-cerebralvascular disease(74.2％ vs.53.5％),neurological disease ( 9.4 ％ vs.5.0％),obstetric disease ( 27.5％ vs.10.1％),menstrual disorder (21.4％vs.14.4％),getting married before aged 21 years (51.5％vs.40.8％),being pregnant more than 4 times(50.2％vs.40.9％),the experience of both cesarean and natural birth (4.0％vs.0.8％),constipation(40.2％ vs.29.4％),fecal incontinence ( 13.1％ vs.4.0％),uneasy movement ( 22.5％vs.10.6％) and drinking (8.6％vs.3.5％) were higher in women with UI than in women without UI (P＜0.05 or P＜0.01).Eight risk factors that were entered into logistic regression model included getting married before 21 years old (OR =1.5,95 ％ CI:1.0-2.3,P＜0.05),being pregnant more than 4 times(OR=1.7,95％CI:1.1-2.4,P＜0.05),menstrual disorder(OR=1.7,95％CI:1.0-2.7,P＜0.05),respiratory disease(OR=1.6,95 ％CI:1.0-2.6,P＜0.05),urological disease(OR=2.4,95 ％CI:1.4-4.1,P＜ 0.01 ),cardio-cerebralvascular disease ( OR =2.0,95 ％ CI:1.3-3.0,P ＜ 0.01 ),obstetric disease(OR=3.4,95％CI:2.0-5.6,P＜0.01),moving uneasily(OR=2.5,95％CI:1.5-4.0,P＜0.01).Conclusions UI is a common disease among women residing at nursing homes.Specific measures including intervention and clinical treatment targeting risk factors should be conducted.

Objective:To investigate the clinical manifestations and imaging features of spastic paraplegia caused by spinal cord Wallerian degeneration after pontine infarction, and to analyze its occurrence process and mechanism.Methods:The clinical manifestations and imaging features of two patients with spastic paraplegia caused by spinal cord Wallerian degeneration after pontine infarction were reported for the first time in China. Combined with anatomy and review of the literature, the mechanism, imaging manifestations and clinical features of Wallerian degeneration of lateral funiculus of spinal cord after pontine infarction were analyzed systematically.Results:Case 1 was a 65 years old female, and case 2 was a 58 years old male, who were treated in Qilu Hospital of Shandong University on December 7, 2018 and June 23, 2019 respectively. All the two patients presented with strength weakness of both limbs, hypertonia, symmetric hyperreflexia, and bilateral extensor plantar responses, which suggested spastic paraplegia secondary to upper motor neuron involvement. Spastic paraplegia appeared eight months after pontine infarction in case 1 and appeared six months after pontine infarction in case 2. Magnetic resonance imaging revealed continuous iso-T 1 and high-T 2 signals of bilateral pyramidal tracts below the pontine foci. Case 1 showed lesions of lateral cord of medulla oblongata, cervical spinal cord and thoracic spinal cord, and case 2 showed lesions of lateral cord of medulla oblongata and cervical spinal cord. At the same time, motor neuron disease and metabolic disease were excluded by electromyography and laboratory examination, inflammatory demyelinating disease was excluded by cerebrospinal fluid examination in one case. The syndromes, in combination with a continuous strip of abnormal signal revealed by magnetic resonance imaging which was consistent with the pyramidal tract and connected with the primary lesion suggested wallerian degeneration of spinal cord secondary to pontine infarction. The clinical symptoms of two cases were gradually aggravated in follow-up. Conclusions:Spinal cord Wallerian degeneration is a sequel after pontine infarction, which is related to the prognosis of the disease. A full understanding of its clinical manifestations and imaging features can avoid clinical misdiagnosis as other diseases.
