Objective To investigate the effect of clinical nursing pathway on patients with cerebral infarction. Methods Two hundred patients with cerebral infarction were randomized by random digit table into the clinical pathway group and the conventional nursing group.The former was managed with the clinical nursing pathway and the latter received conventional nursing. The neurologic impairment and the activities of daily life were assessed respectively by national institute of health stroke scale(NIHSS) and Barthel index(BI).The two groups were compared in terms of hospital stay,medical expense,patient’s satisfaction and curative effect. Results Compared to the conventional nursing group,the clinical pathway group was shorter at hospital stay,lower at lower hospitalization cost,higher at patient’s satisfaction and higher in the score by Barthel index,compared to the conventional nursing group(all P<0.05). Conclusion The application of clinical nursing pathway in patients with cerebral infarction can improve the activities of daily living and the quality of care,shorten length of stay,reduce medical cost and increase patients’satisfaction drgree.

Objective:To evaluate the curative efficacy of tacrolimus (FK506)combined with corticosteroids in the treatment of idiopathic membranous nephropathy (IMN ), and to analyze the response of anti-M-type phospholipase A2 receptor (PLA2R)antibody to the treatment.Methods:Sixty-one adult IMN patients were divided into FK506 group (FK506 combined with corticosteroids,n = 24)and CTX group (cyclophosphomide combined with corticosteroids,n=37)according to their willing to the acceptance of different immunosuppressives. The remission rates of the patients at 4,8,12 and 24 weeks after treatment in two groups were analyzed.The ELISA method was used for the detection of serum anti-PLA2R antibodies of the patients before and after treatment.The antibody level changes were observed and the difference of remission rates was compared between the antibody positive patients and the negative patients in FK506 group.Results:The total remission rates of the patients in FK506 and CTX groups 24 weeks after treatment were 91.7% and 64.9% respectively and the total remission rate of the patients in FK506 group was significantly higher than that in CTX group (P < 0.05).The total remission rates at 8,12,24 week after treatment and the partial remission rates at 12 and 24 weeks in FK506 group were significantly higher than those in CTX group (P <0.05).The anti-PLA2R antibody positive rates in FK506 group and CTX group were 75.0% and 70.3%,respectively;the negative conversion rate of anti-PLA2R antibody at 24 weeks after treatment in two groups were 61.6% and 57.7%,respectively;there were no significant differences between two groups (P >0.05).The total remission rates of the antibody positive patients and negative patients at baseline in FK506 group 24 weeks after treatment were 88.9% and 100.0%,respectively;there was no significant difference (P > 0.05).Except the characteristic side effects of corticosteroids,the patients in FK506 group presented no hyperglycemia,tubulointerstitial damage,hepatic lesion or neurotoxicity. But the patients in CTX group showed mild hepatic lesion or gastrointestinal symptoms.Conclusion:The remission rate of FK506 combined with corticosteroids is higher than that of CTX combined with corticosteroids in the treatment of IMN patients.FK506 treatment has relatively rapid effect and less side effects as well.The negative conversion of serum anti-PLA2R antibody follows the remission after treatment;however,the negative conversion rate has no significant difference between FK506 group and CTX group.The remission rate of IMN patients treated with FK56 combined with hormone has no relationship with the baseline anti-PLA2R antibody.

Aim To investigate the effects of predni-sone on trabecular microstructure and biomechanical properties of femur in a rat model of type II collagen-induced arthritis (CIA ) using micro-CT and biome-chanics.Methods Forty 8-week-old male Lewis rats were randomly divided into 2 groups:control (CON ) group with 6 rats,and the remaining 34 rats were used to establish the CIA model.3 weeks after immunization screening CIA rats were randomly divided into CIA group,CIA plus prednisone 4.5 mg · kg-1 · d -1 group and CIA plus prednisone 9 mg · kg-1 · d -1 group.Rats in CON group were given vehicle as well as in CIA group.Rats in the other two groups were treated with prednisone at 4.5 mg·kg-1 ·d -1 or 9 mg ·kg-1 · d -1 .After 90 days treatment,all rats were euthanized,and the left femur was collected for biome-chanics,micro-CT scanning and three-dimensional re-construction.Results Micro-CT data showed that tra-becular thickness,trabecular number,bone volume/total volume,bone mineral density in CIA group were significantly lower than those in CON group.While tra-becular separation,structure model index were signifi-cantly higher than those in CON group.Compared with CON group,biomechanical properties (elastic load, maximum load,break load and stiffness)were signifi-cantly decreased in CIA group.Compared with CIA group,bone volume/total volume and trabecular num-ber were increased,while trabecular separation was significantly decreased in two prednisone groups.Com-pared with CIA group,there was no significant change in biomechanical properties in two prednisone groups. Conclusions Treatment with prednisone for 3 months can ameliorate the damage of trabecular microstructure of the femur in CIA rats,but it has no effect on biome-chanical properties and bone mineral density.

Objective To understand the clinical epidemiology of nosocomial candidemia in Huashan Hospital during a 10-year period. Methods One hundred and nine cases of nosocomial candidemia in Huashan Hospital affiliated Fudan University during the period of 1998- 2007 were retrospectively reviewed. The underlying conditions, risk factors, clinical manifestations, treatment and outcome were described. The prognostic factors were analyzed by chi square test or Fisher exact probability test. Multivariate analysis was done by multiple Logistic regression. Results The average annual incidence of nosocomial candidemia during the study period was 0.28/10 000 patients per day.The most common pathogen was C. albicans (59/109,54.1%), followed by C. tropicalis (20/109,18.3%), then C. parapsilosis (11/109, 10. 1%), C. glabrata (11/109, 10.1%), and other Candida spp. (8/109, 7.3% ). Underlying diseases frequently identified included diabetes (50,45.9%), solid malignancy (32, 29.4%), head trauma (13, 11. 9%) and stroke (12, 11.0%).There were 37 cases who died or deteriorated. The overall mortality was 34.0% and the attributable mortality was 22. 0% (24/109). In multivariate prognostic analysis, retention of central venous catheters (OR: 5.42, 95% CI: 1.68-17.41, P＝0.005), corticosteroid medication (OR: 3.69,95% CI: 1.10-12.34, P=0. 034), and severe sepsis on the day of candidemia (OR: 2.94, 95% CI:1.72-15. 21, P = 0. 003) were factors independently correlated to increased mortality. Furthermore,adequate antifungal therapy was the only independent predictor of decreased overall mortality (OR: 0. 27,95% CI: 0. 09-0. 78,P=0.015). Conclusions The incidence of nosocomial candidemia in our hospital has been increasing during the past decade. Timely diagnosis and treatment plays a key role in the management of nosocomial candidemia,

Objective To investigate the polymorphism profile of cytochrome P_(450)2C19 (CYP2C19) in Chinese patients with invasive fungal infections. Methods Two major single nucleotide polymorphism loci of the CYP2C19 gene (CYP2C19 * 2 and CYP2C19 * 3) were genotyped with PCR and restriction fragment length polymorphism (PCR-RFLP) in 134 patients with invasive fungal infections and 134 healthy volunteers. Allele frequencies and the proportions of metabolizer phenotypes were compared. Results In patients with invasive fungal infections, CYP2C19 * 1, CYP2C19 * 2 and CYP2C19 * 3 alleles showed frequencies of 58.2%, 36.6% and 5.2%. In healthy volunteers, the frequencies of CYP2C19 * 1, CYP2C19 * 2 and CYP2C19 * 3 were 63.4% , 34. 3% and 2. 2%. There was no significant difference in allele frequencies between the two groups. Of the patients with invasive fungal infections, 33. 6% were homozygous extensive metabolizers, 50.0% heterozygous extensive metabolizers and 16.4% poor metabolizers. Of the healthy volunteers, 40.3% were homozygous extensive metabolizers, 48.5% heterozygous extensive metabolizers and 11. 2% poor metabolizers. The proportions of metabolizer phenotypes were similar between the two groups. Conclusions Significant CYP2C19 polymorphism was detected in both groups. Approximately two thirds of the Chinese patients were either heterozygous extensive metabolizers or poor metabolizers. The genetic polymorphism may have important effect on drug metabolism in these patients

Objective To find out the association between the indicators(pulse concussion lung function test index) of bronchial hyperresponsiveness (BHR) with fractional concentration of exhaled nitric oxide (FeNO) at different control periods among preschool asthmatic children.Methods Totally 74 asthmatic children in the pediatric department of our hospital from April 2015 to February 2017 were enrolled in this study,and 25 children undergoing the lung function and FeNO examination served as the controls,aged 3-5 years old.The cases were divided into three groups according to the standard in 2016 version of the Prevention and Treament Guide of Children Bronchial Asthma:asthma control group(n =26),asthma non-control;group(n =48) and control group (n=25).All data of FeNO,resistance of the respiratory system at 5 Hz(R5),resistance of the respiratory system at 5 Hz (R20),difference of R5 and R20(R5-20),reactance area (AX),reactance of the respiratory system at 5 Hz (X5) and resonant frequency of reactance (Fres) were collected.The FeNO,pulse concussion lung function test value and their association were analyzed.Results (1) The FeNO value of asthma the non-control group was significantly higher than that of the asthma control group and the control group,which were 34.00 ± 18.17,20.23± 11.07 and 28.00± 17.30 respectively.The AX detection value of the asthma non-control group was significantly higher than that of the control group(37.29 ± 15.27 vs.30.17 ± 9.50,P＜0.05).(2)R20 had weak correlation with FeNO in the control group(P＜0.05),while R20 had no correlation with FeNO in the non-control group and control group (P＞0.05).FeNO had no obvious correlation with R5,R520,AX,X5 and Fres in the asthma non-control group,asthma control group and control group(P＞0.05).Conclusion In preschool children with asthma,FeNO can reflect the airway eosinophilic inflammation control,and does not reflect the airway hyperresponsiveness.Thereforeit ie needed to combined with FeNO and IOS indicators (airway hyperresponsiveness index AX,etc.),which can more precisely judge whether asthma being controlled.

Objective To analyze the clinical features of patients with uncommon fungal infections in central nervous system (CNS).Methods Thirty-five patients with uncommon CNS fungal infections who were admitted to Huashan Hospital from 1997 to 2010 were retrospectively reviewed.The pathogens,symptoms and signs.treatments of patients were evaluated.The data were analyzed by rank sum test and Fisher'S exact test.Results Twenty-nine of the 35 patients met the definition criteria of prover CNS fungal infections,while the other 6 had probable diagnosis.Predisposing factors were found in 86% of all patients.The most common pathogens were Aspergillus and Candida species.The symptoms and signs commonly occurred including fever(22 cases),headache(19 cases), cranial neuropathy(12 cases),and meningeal irritation sign(12 cases).High white blood cell count,high protein level,and low glucose level were the main findings of cerebrospinal fluid (CSF) analysis.Patients with cerebral aspergillosis were more frequently accompanied with immunocompromised conditions, and they often got CNS aspergillosis from hematogenous dissemination or direct extension of paranasal sinus infection.Cerebral granuloma and abscess were the common clinical characteristics of CNS aspergillosis.Cerebral candidiasis often arose from neurosurgical surgery or traumatic brain injury,and these patients were usually presented with meningitis.All patients were treated with antifungal drugs and (or) surgical intervention and 77%(27/35) of the patients achieved complete or partial responses. Antifungal agents combined with surgical resection might improve outcome of patients with CNS aspergillosis; while removal or replacement of drainage tubes in combination with antifungal treatment showed satisfactory efficacy in patients with cerebral candidiasis who usually had shunt manipulation. Conclusions The incidence of CNS fungal infection, such as cerebral aspergillosis and candidiasis, is increasing. Early diagnose and therapeutic intervention are crucial for improving outcome.

Objective To describe the distribution of mannose binding lectin (MBL) genetic polymorphisms in non-acquired immunodeficiency syndrome (AIDS) patients with cryptococcosis in China and to verify the association of MBL polymorphisms with susceptibility to cryptococcosis.Methods The case-controlled genetic association study was conducted and 167 non-AIDS patients with cryptococcosis and 208 healthy controls were recruited. Genome DNA was extracted from the peripheral blood and MBL gene was amplified by polymerase chain reaction (PCR). Six singlenucleotide polymorphisms ( SNP) of MBL gene were sequenced. The association of MBL polymorphisms with susceptibility to cryptococcosis were analyzed. The comparison between patients and controls was performed by chi square test or Fisher's exact test. The differences of MBL plasma concentrations between groups with different MBL genotypes were compared by single factor variance analysis. Results There were no differences between patients and controls in terms of MBL genotype frequencies, haplotypes and genotypes (all P>0. 05). Compared with healthy control, the deficient MBL-producing genotypes were strongly associated with cryptococcal meningitis (16. 5% vs 8. 7%,χ2=4.25, P=0.0392, OR = 2.09), particularly in patients without underlying immunocompromised conditions (21. 4% vs 8. 7%, χ2 =7. 15, P = 0. 0075, OR = 2. 88). Individuals with MBL deficiency genotypes showed significantly higher rates of central nervous system (CNS) cryptococcal infection rather than non-CNS cryptococcosis (16. 5% vs 3. 1%, Fisher's exact test, P = 0. 010, OR = 6. 13).The difference was even more significant in the immunocompetent patients (21. 4% vs 4. 0%, P =0.009, OR= 6. 55). Conclusion MBL deficiency is associated with cryptococcal meningitis and may play a role in CNS Cryptococcus infection.
