Objective To evaluate the risk factors for healthcare-associated infection(HAI)in senile dementia pa-tients,so as to adopt effective nursing measures to reduce the incidence of HAI.Methods Clinical data of 82 senile dementia patients aged≥60 years and hospitalized between January 2011 and June 2013 were analyzed retrospective-ly.Results Of 82 patients,28 (34.15%)developed HAI.The main infection site was lower respiratory tract(n=15,53.57%),followed by urinary tract(n=6,21 .43%).Univariate analysis revealed that risk factors for HAI in senile dementia patients were bedridden,long length of hospital stay ,dysphagia,indwelling urinary catheter,irra-tional use of antimicrobial agents,combined with tumor,and hypoproteinemia (all P <0.05 ).The main isolated bacteria were gram-negative bacilli(n=40,62.50%),the top three pathogens were Klebsiella pneumoniae (n=12, 18.75%),Escherichia coli (n =10,15.63%),and Pseudomonas aeruginosa (n =8,12.50%).Conclusion Reali-zing the risk factors and common pathogens of HAI in senile dementia patients is helpful for taking effective meas-ures to prevent and control the incidence of HAI .

Objective:The protein of missing in metastasis (MIM), a novel discovered actin-binding scaffold protein, is involved in actin cytoskeleton rearrangements, signal transduction and transcriptional activation, and has close association with tumor growth, invasion, and metastasis. Recently, much focus has been placed on the role of MIM performed in tumor progression. In recent years, more and more attention is focused on its action mechanism in various kinds of tumors, which has a wide foreground of investigation. In this paper, we make a comprehensive review of the association of MIM with cancer development, in order to provide the theoretical basis and new strategies for application of MIM proteins in cancer diagnosis and treatment.

AIM: To investigate the application of phrenic nerve conduction time(PNCT) in the recovery of general anaesthesia. METHODS: Pdi (t) and PNCT were measured by cervical magnetic stimulation of phrenic nerves in 8 patients before and after the administration of muscle relaxant. RESULTS: Pdi (t) was reduced from (23.7?2.4) cmH 2O to (11.5?3.4) cmH 2O (reduction rate: 51.5%, P

Objective To analyze the clinical characteristics and risk factors of nosocomial infection (NI) in elder patients with cerebral infarction Methods A retrospective study was performed.Three hundred and two patients over 60 years old with cerebral infarction were selected as our subjects,who were in a cadre ward from Jan.2011 to Jun.2013.The incidence rate of NI and the predisposing factors of NI were investigated.Results Of 302 patients with cerebral infarction,46 cases developed NI and the incidence was 15.23％.The most common site of NI was lower respiratory tract infection,counting for 60.87％ (28/46),followed by urinary tract infection(21.74％ (10/46)).The risk factors of NI included age,prolonged hospitalization,disturbance of consciousness,invasive operation and the use of antibiotics (x2 =5.720,11.517,5.185,4.218,11.931 ; P ＜ 0.05).Conclusion The clinical staff should pay close attention to the risk factors of NI in elder patients with cerebral infarction.The methods include controlling the disease as soon as possible,shortening hospital stays,reducing invasive operation and the rational use of antibiotics can reduce the incidence of NI.

Objective To discuss MRI and pathological features of intracranial hemangioblastoma.Methods MRIdata of 26 cases of hemangioblastoma confirmed with operation and pathology were analyzed retrospectively.Results There were 22 cases with single lesion and multiple lesions in 4 eases.And a total of 31 lesions located in the posterior cranial fossa,including 14 lesions in right cerebellar hemispheres,9 lesions in left cerebellar hemispheres,2 lesions in cerebellar inferior vermis,4 lesions in medulla oblongata,and 2 lesions in fourth ventricle.Ninteen lesions showed cystic nodular type,1 lesion was cystic type,11 lesions showed parenchymal type or partial parenchyma type.Cystic lesions showed long T1 and long T2 signal,T1WI of solid area showed slightly long T1 and slightly long T2 signal,of which 12 lesions were slightly shorter T1 signal.Solid areas significantly enhanced,cystic area had no enhancement,but cystic wall of 3 cystic nodular lesions were slightly enhanced.DWI of solid areas showed low signal.MRS showed the peak of Cho obviously increased,and the peaks of Cr and NAA obviously decreased or nearly disappeared,and the high peak of lipids and lactate were observed.Conclusion The conventional and functional MRI of intracranial hemangioblastoma have some characteristics,MRI has a great value in the diagnosis and localization of intracranial hemangioblastoma.

Objective:To explore the clinical risk factors of post-transplantation diabetes mellitus (PTDM) and establish a risk prediction model in kidney recipients.Methods:The clinical data and postoperative bedside measurements of blood glucose (BG) were retrospectively reviewed for 305 renal transplant recipients at First Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to August 2019.According to whether or not PTDM occurred, they were assigned into two groups of PTDM (n=34) and non-PTDM (n=271). Risk factors were screened through single/multi-factor Logistic regression and PTDM prediction model was established.Results:The incidence rate of PTDM was 11.15%(34/305). Logistic regression analysis indicated that deceased donor, age ≥40 years, female, pre-hemoglobin A1c (Pre-HbA1c) and postoperative bedside BG value ≥11.1 mmol/L were the correlated factors for the occurrence of PTDM.Among them, female ( OR=3.13, 95% CI: 1.28-7.61), Pre-HbA1c ( OR=2.05, 95% CI: 1.12-3.74) and BG ≥11.1 mmol/L at 4pm Day 2/3 post-operation ( OR=19.08, 95% CI: 4.34-83.87) were risk factors for the occurrence of PTDM, The area under the model curve was 0.86 (95% CI: 0.79-0.93) with a Jordan index of 0.65, a sensitivity of 82.8% and a specificity of 82.3%. Conclusions:Female, Pre-HbA1c and fasting BG at 4 pm Day 2/3 post-operation ≥ 11.1 mmol/L are risk factors for the occurrence of PTDM.The prediction model has a decent predictive value.It is conducive to early clinical interventions and lowering the incidence rate of PTDM.

Objective:To describe demographic,clinical and physiological characteristics,treatment between first-episode major depressive disorder(MDD)and relapse MDD,and to explore characteristics of relapse MDD.Methods:Totally 858 patients who met the diagnostic criteria for depression of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),were included by using the Mini International Neuropsychiatric Interview(MINI),Clinician-Rated Dimensions of Psychosis Symptom Severity,and Hamilton Depression Scale etc.Among them,529(58.6％)were first-episode depression and 329(36.0％)were relapsed.The differences of demographic characteristics,clinical and physiological characteristics,treatment were compared byx2test and Kruskal-Wallis rank sum test.Multivariate logistic regression was used to explore the characteristics of MDD recur-rence.Results:Compared to first-episode MDD,relapse MDD had more comorbidity(OR=2.11,95％CI:1.00-4.44),more days out of role(OR=1.26,95％CI:1.01-1.56),more history of using psychiatric drug more than one month(OR=1.41,95％CI:1.02-1.97)and electroconvulsive therapy(OR=3.23,95％CI:1.42-7.36),and higher waist-hip ratio(OR=33.88,95％CI:2.88-399.32).Conclusion:Relapse MDD has positive as-sociation with comorbidity of mental disorders,out of role,and higher waist-hip ratio.
