Objective:To investigate the curative effect of early enteral nutrition support in patients with COPD complicated with respiratory failure.Methods: When mechanical ventilation began,63 patients in the acute phase of COPD complicated with respiratory failure were divided into two groups: the early enteral nutrition group(EEN group,n=32) or the delayed enteral nutrition group(DEN group,n=31).After two weeks,the nutritional indexes,the times of mechanical ventilation,the incidence of complication and the mortality were observed.Results: Two weeks later,there was significant difference between EEN group and DEN group in total protein,albumin,prealbumin and hemoglobin(P

To have a better understandings of the clinical features and pathology of the central nervous system of thrombotic thromocytopenic purpura(TTP) in order to avoid its misdiagnosis and improper treatment, we reported here the clinical features of the central nervous system of 2 cases with TTP and pathologic changes in the brain of one case of them.The result showed that in 2 young women presented with atypical clinical features and laboratory findings of TTP, the main presentations of the central nervous system included language disturbances, hemiplegia, delirium, scream, confusion, unconsciousness.Both of them had an acute progresive course. One case died after steroids therapy alone and the other got complete remissions after conbined treatment with plasmapheresis and steroids. Pathological examination of the brain of the died case showed widespread hyaline thrombosis in small vessels and ischaemic changes of the neurons in the hippocampus and the cerebral cortex. Our conclusion is there are various patterns of clinical presentations of the CNS in TTP and the disturbances are due to widespread thrombotic microangiopathy and failure of cerebral perfusion.

As the basis of the health management of the elderly, weight management should receive attention from medical practitioners.However, there is an ongoing debate on the ideal range of body mass index for elderly in China.This article aimed to find the suitable body mass index for Chinese old people by reviewing the literature regarding the body mass and obesity of the elderly.Lots of evidence show that overweight and mild obesity appear to be the optimal weight status for the elderly.

Objective:To investigate the efficiency of maternal serum triple screening for the genetic abnormality in second-trimester and the morbidity of adverse pregnancy outcome in false positive results of the test. Methods: A total of 4 680 pregnant women with singleton pregnancies assigned in Obs & Gyn Hospital, Fudan University, underwent triple screening test (alpha fetoprotein, AFP; human chorionic gonadotropin, HCG and unconjugated estriol, uE3) by fluorescence enzyme immunoassay between 2003 and 2005. The valid MoM (Multiples of Median) value of mid-trimester serum AFP, uE3, and hCG and risk assessments was provided by Beckman Coulter Co. When applied in the prenatal Down syndrome screening service. The study compares the incidence of chromosomal abnormalities with Down syndrome in screen positive women and compares to the MoM value established in the literature. The risks of having a fetus with congenital abnormalities or of developing obstetric complications in the screen positive women with their matched controls.Results:The MoM values for the triple tests of our study are similar to established values of literature. Only 51.01% women with pregnancies agree to receive screening. Amniocentesis utilization rate was 55.12% in the screen-positive pregnancies. The false positive rate was 6.89% and the median of maternal age of the women was 28.13 (range 19 to 49) years old. Chromosomal abnormalities were identified in 21 pregnancies, including 9 cases of trisomy 21.The detection rate was 77.77%. Pregnancies with positive screening results had a significantly higher risk of adverse outcomes than those with negative results (P< 0.05). Whereas there was no difference in the incidences of fetal congenital appearance or skeleton abnormality. Conclusion: Adjusting MoM values of local unaffected populations is limited to increasing the detection rate. Because chromosomal defects have variable exhibitions, amniocentesis utilization is still a choice for screen-positive pregnancies. Screen-positive pregnancies had increased risk of chromosomal abnormalities.

Objective To analyze the incidence,risk factors and pathogens of stroke associated pneumonia (SAP) in patients with acute stroke in the intensive care unit (ICU).Methods One hundred and forty-two patients with acute stroke admitted in ICU from January 2012 to December 2013 were retrospectively studied.The data of medical history of patients,treatment,prognosis,and pathogens of SAP were collected.Data were analyzed by t test,Mann-Whitney U test,Pearson x2 test and muhivariable logistic regression.Results Of 142 patients,94 (66.2％) were contracted SAP of which 54.3％ were early-onset pneumonia (EOP≤72 h) and 45.7％ were late-onset pneumonia (LOP ＞72 h).The most common pathogens isolated from EOP were Staphylococcus aureus and Klebsiella pneumonia,while the most common pathogens isolated from LOP were Acinetobacter baumanii,Staphylococcus aureus and Pseudomonas aeruginosa.Multivariate logistic regression analysis demonstrated that hemorrhagic apoplexy,history of stroke,higher APACHE score,dysphagia,prolonged use of mechanical ventilation,prolonged stay in ICU,and hyperglycemia were the independent risk factors of SAP,and the odds ratios (OR) with 95％ confidence intervals (CI) were 10.917 (1.834-60.959),15.223 (1.947-96.969),1.607 (1.253-2.062),5.321 (1.225-26.519),1.809 (1.208-2.709),1.391 (1.085-1.783),1.534 (1.l01-2.138),respectively.While plasma albumin level was negatively associated with SAP (OR =0.809,95％ CI:0.674-0.971).The common risk factors of EOP and LOP were higher APACHE score and prolonged use of of mechanical ventilation.The independent risk factors of EOP were dysphagia (OR =4.331,95％ CI:1.330-14.098),history of stroke (OR =13.690,95％ CI:2.198-85.277) and chronic bronchitis (OR =12.907,95％ CI:1.203-138.542),While those of LOP were prolonged stay in ICU (OR =1.687,95 ％ CI:1.131-2.517),hemorrhagic apoplexy (OR =21.657,95％ CI:1.559-106.752) and low plasma albumin level (OR =0.782,95％ CI:0.637-0.961).There was no significant difference in mortality between EOP (49％) and LOP (44.2％) (P ＞ 0.05),but the mortality of SAP was significantly higher than that of non-SAP group.Conclusions The incidence rate and mortality of SAP are quite high in ICU.The pathogens and risk factors are different between EOP and LOP.This observation results suggest it is important to identify high-risk stroke patients,and to develop a novel treatment strategy and prophylactic measures facilitating limiting the complications of stroke.

Objective To determine whether stroke volume variation (SVV) in relation to volume loading in mechanically ventilated patients with septic shock.Methods Data of thirty-two mechanically ventilated patients with septic shock admitted from Dec 2009 to May 2012 were prospectively analyzed.Cardiac index (CI),stroke volume (SV),systemic vascular resistance index (SVRI) and stroke volume variation (SVV) were measured by FloTrac/Vigileo before and after fluid resuscitation (250 mL saline in 10 min).Patients with an increase in SV (△SV) ≥ 10％ and ＜ 10％ after fluid volume loading were classified as responders and non-responders,respectively.The comparisons between these two sorts of patients were assessed by using two sample Student' s t-test,and comparisons between changes before and after fluid challenge were assessed by using a paired Student' s t-test.A Pearson' s correlation analysis was employed for evaluate the correlation between △SV and other haemodynamic variables.The roles of SVV,central venous pressure (CVP),mean artery pressure (MAP) and the changes of CVP (△CVP),MAP (△MAP) after fluid administration in predicting volume responsiveness were evaluated by receiver operating characteristic (ROC) curve.Results Thirty-two patients with septic shock were included in this study.There were 54 instances of fluid challenge performed,among which 35 instances were defined as response group.Significantly increased SV induced by fluid challenge was assigned into response group (83.6 ± 15.6) mL vs.(68.5 ± 14.2) mL,P ＜0.01,while in non-response group,there were no significant change in SV (P ＞0.05).SVV was significantly correlated with SV before fluid loading (r =0.522,P ＜ 0.01).The area under the ROC curve (AUC) for stroke volume variation (SVV) was 0.898 (95％ CI:0.796-1.000).Using SVV ≥ 11.5％ as the threshold to predict fluid responsiveness,the sensitivity was 94％ and specificity was 84％.Conclusions SVV can be used to predict fluid responsiveness in patients with septic shock.

Objective To evaluate hepatic segment vascular occlusion technology in precise resection of liver segment.Methods Sixty-seven cases of liver cancer patients who underwent precision liver segment resection from August 2007 to May 2012 in Qilu Hospital were analyszed retrospectively.There were 51 male patients and 16 female patients,age ranging from 45 to 66 yrs.Results All operations were performed successfully.All cases were with single tumor,the diameter ranged from 2 cm to 6 cm.Resection of segment Ⅲ was performed in 22 cases,segment Ⅳ in 10 cases and segment Ⅵ in 35 cases.Operation time was 50-120 minutes,and the average time was 73 minutes.Blood loss was 50-200 ml,averaging 86 ml.No patient needed blood transfusion.Postoperative incisional liquefaction was found in 6 cases which were cured with interference in time.There was no bile leakage,hemorrhage,celiac infection and complications such as liver failure.The average hospital stay was 7.8 days.No rccurrence was found during 3 months follow-up.Conclusions Hepatic segment vascular occlusion technology was safe and feasible in precise resection of liver segment in liver cancer patients.It effectively controlled blood loss and reduced liver damage.

Objective To evaluate the efficacy of accelerated partial breast irradiation ( APBI ) and whole breast irradiation ( WBI ) with simultaneous integrated boost ( SIB ) from the perspective of economics, and provide a reference for postoperative adjuvant therapy mode selection for early-stage breast cancer after breast-conserving surgery. Methods A total of 355 early-stage breast cancer patients who underwent APBI or WBI-SIB after breast-conserving surgery were evaluated on efficacy and cost-effectiveness, of which 177 patients received APBI, and 178 patients received WBI-SIB. Survival analysis was done according to treatment received. NCI-CTC 3.0 was used to score the toxicities. Breast aesthetic outcome were evaluated with Harris standards. Results Median follow-up was 42 months ( 5.8 -92.7 months) . The 3-year locoregional recurrence free survival( LRFS) rates in APBI group and WBI-SIB group were 98.2％ and 97.6％, distant metastasis free survival( DMFS) were 94.3％ and 93.7％, disease-free survival ( DFS) were 93.1％ and 91.6％, and overall survival 95.5％ and 94.3％, respectively, without statistically significant differences(P>0.05). Compared with WBI-SIB group, the acute reaction rates in APBI group decreased from 5. 6％ to 3.4％(χ2 =6.044, P <0. 05), and late reactions from 5.6％ to 2.3％ (χ2 =6.149, P<0. 05), while the cosmetic outcome improved from 88.8％ to 93.8％(χ2 =5.22, P<0. 05). Moreover, the processing average time was shortened by 26.5 d (χ2 =40.76, P<0. 05). Conclusions After breast-conserving surgery, the efficacy of APBI showed no difference from WBI-SIB with respect to 3-year local control, disease-free survival, and overall survival, but displayed a significantly better toxicity profile and cost-effectiveness ratio for early breast cancer patients. It can be used as a good radiotherapy model after breast-conserving surgery in early-stage breast cancer.
