Objective To investigate the cognition and care needs of the patients with acute stage fracture thus providing reference for the construction of intermediate care model. Methods The data of 504 patients with acute stage fracture from December 2014 to April 2015 were investigated through questionnaire, and analyzed. The issues included gender, age, marital status, cultural level, degree of understanding of intermediate care, care needs, etc. Results 63.29%(319/504) of the patients didn′t know intermediate care before they filled in the questionnaire,only 3.97%(20/504) of the patients understood the conception of intermediate care; different stage of age had different cognition towards intermediate care, the differences were statistically significant( χ2=148.771, P<0.01); different stage of age, sex, marital status, cultural level had different care needs, the differences were statistically significant (H/u=9.692-129.097, P<0.05). Conclusions At present, the majority of patients have no conception about intermediate care, so it is necessary to build the model of intermediate care. As nursing staff we should provide different help according to different type people, thus we can promote patients' physical and mental health, improve patient satisfaction to the greatest extent.

Objective To compare the different characteristics of adaptive support ventilation (ASV) and synchronized intermittent mandatory ventilation-pressure support ventilation (SIMV-PSV) mode in weaning patients after general anesthesia.Methods One hundred and twenty-eight patients received general anesthesia,ending in odd and even numbers by hospital number divided into ASV group (single number,62 cases) and SIMV-PSV group (double number,66 cases).The propofol dosage,duration of mechanical ventilation,duration of intubation,ventilator alarms,ventilator settings manipulations and each stage of the blood gas analysis,hemodynamic,respiratory mechanics were recorded.Results One hundred and twenty-eight patients completed the extubation.The propofol dosage,duration of mechanical ventilation,duration of intubation in ASV group were significantly shorter than those in SIMV-PSV group [(1.13 ± 0.33)mg/kg vs.(1.28 ±0.49) mg/kg,(169.8±36.5) min vs.(201.9 ±37.3) min,(197.2 ±38.9) min vs.(239.5 ± 42.3) min,P ＜ 0.05].There was no statistically significant difference in various stages of heart rate,mean arterial pressure,central venous pressure,pH,arterial carbon dioxide partial pressure,oxygenation index between two groups (P ＞0.05).In the first and second stages,tidal volume in ASV group was significantly higher than that in SIMV-PSV group [(543.6 ± 72.3) ml vs.(489.5 ± 68.7) ml,(513.9 ± 65.7)ml vs.(462.8 ± 61.7) ml,P＜ 0.05],respiratory rate in ASV group was significantly lower than that in SIMV-PSV group [(13.2 ± 3.6) times/min vs.(17.2 ±4.1) times/min,(15.1 ± 3.1) times/min vs.(16.8 ± 3.7)times/min,P ＜ 0.05].In the first stage,the mean airway pressure and peak airway pressure in ASV group were significantly lower than those in SIMV-PSV group [(8.2 ± 1.7) cm H2O (1 cm H2O =0.098 kPa) vs.(12.3 ± 3.1) cm H2O,(16.2 ± 2.9) cm H2O vs.(21.2 ± 4.3) cm H2O,P ＜ 0.05].The pulmonary dynamic compliance in ASV group was better than that in SIMV-PSV group [(64.8 ± 12.3) ml/cm H2O vs.(52.6 ±13.5) ml/cm H2O,P ＜ 0.05].The ventilator alarms,ventilator settings manipulations in ASV group were significantly shorter than those in SIMV-PSV group [(2.3 ± 1.6) times vs.(5.1 ± 1.9) times,(0.8 ± 0.5) times vs.(1.6 ± 0.8) times,P ＜ 0.05].Conclusion ASV weaning mode is safe and effective,which could accelerate the extubation and simplify the manipulation.

Objective To study the concentration of anti-cyclic citrullinated peptide antibody (CCP),rheumatoid factor (RF),immunoglobulin (Ig) in synovial fluid and serum of patients with rheumatoid arthritis (RA),and the positive rate of anti-keratin antibodies (AKA) and anti-perinuclear factor (APF) were also measured.The aim was to explore the diagnostic value of these antibodies in synovial fluid for RA.Methods Thirty RA patients were collected,synovial fluid were withdrawn from the inflamed joints and peripheral blood were collected at the same time.Anti-CCP antibody,AKA,APF and RF were measured.The cut-off value of CCP in synovial fluid was determined through operating characteristic curve (ROC curves) analysis.The antibody levels in serum and synovial fluid were compared.Statistical analyses were performed using t test,and Pearson's correlation test.Results The cutoff value of CCP in RA synovial was higher,which was 29.00 U/ml,with the sensitivity of 87.00％ and specificity of 94.10％.There were significant differences in the concentration among anti-CCP antibody [(326±313) U/ml,(496±454) U/ml,t=-2.399,P＜0.05],IgG [(57±39) mg/L,(173±86) mg/L,t=-7.4792,P＜0.05),RF [(53±36) U/ml,(149±104) U/ml,t=-2.402,P＜0.05] in synovial and blood serum respectively in RA patients.Conchsion The diagnosis of RA is enhanced if anti-CCP antibodies,RF and IgG in synovial fluid are examined.They are supplementary to RA diagnosis and are helpful for clinical practice,especially for patient with very recent-onset RA.

Objective To study the feasibility,safety,indications and possible advantages of minimally invasive surgery over traditional open surgery in treating pancreatic body or tail lesions.Methods From December 2009 to December 2014,the clinical data of 71 patients with lesions in pancreatic body or tail who underwent minimally invasive distal pancreatectomy (MIDP) or open distal pancreatectomy (ODP) at the General Surgery of Huadong Hospital were retrospectively analyzed.There were 22 patients in the MIDP group and 49 patients in the ODP group.The operations in 15 patients in the MIDP group were performed by the Da Vinci robot-assisted surgical system and 7 patients by laparoscopic distal pancreatectomy.Results The MIDP group had a shorter time to pass first flatus [(MIDP (2.5 ± 1.0) d vs ODP (3.5 ±1.0)d,P ＜ 0.05],and shorter postoperative hospital stay [(MIDP (15.2 ± 7.9) d vs ODP (23.4 ±21.2) d,P ＜ 0.05] than the ODP group.There were no significant differences on total pancreatic fistula rate [MIDP 45.5％ (10/22) vs ODP 55.1％ (27/49),P ＞ 0.05] and symptomatic postoperative pancreatic fistula rate [MIDP 18.2％ (4/22) vs ODP 18.4％ (9/49),P ＞ 0.05] between the two groups.The MIDP group had a significant longer operative time [MIDP (246.3 ±75.3)min vs ODP (168.1 ±33.7)min,P＜0.05] than the ODP group.Conclusions Minimally invasive surgery is safe and feasible in treatment of lesions in pancreatic body or tail with less trauma and faster recovery.The application of robotic surgery has expanded the treatment options for lesions in pancreatic body or tail.

Objective To compare the pressor responses to ephedrine during general anesthesia with different drugs.Methods Sixty ASA physical status Ⅰ or Ⅱ patients,scheduled for elective gastrointestinal tumor resection under general anesthesia,aged 20-64 yr,weighing 45-90 kg,were included in this study.The patients were randomized to receive dexmedetomidine + remifentanil + sevoflurane (group Ⅰ,n =20),propofol + remifentanil + sevoflurane (group Ⅱ,n =20),or dexmedetomidine + propofol + remifentanil + sevoflurane (group Ⅲ,n =20) to maintain the depth of anesthesia.Ephedrine 0.1 mg/kg was injected intravenously when the systolic blood pressure (SBP) was decreased to about 90 mm Hg during anesthesia.Blood pressure was monitored and recorded at 1-min intervals for 10 min after the injection.The onset time (TSBP,TDBP,TMAP) for ephedrine to raise the SBP,diastolic blood pressure (DBP) and mean arterial pressure (MAP) and the maximal amplitude (△SBP,△DBP,△MAP) were also recorded.Results Compared with Ⅱ group,TSBP,TDBP and TMAP were significantly shortened,and △SBP,△DBP and △MAP were increased in Ⅰ and Ⅲ groups (P ＜ 0.05).Conclusion Compared with propofol + remifentanil + sevoflurane combined anesthesia,dexmedetomidine + remifentanil + sevoflurane combined anesthesia and dexmedetomidine + propofol + remifentanil + sevoflurane combined anesthesia augment the pressor responses to ephedrine in patients.

Objective To investigate the relationship between EphA2, EphrinAl and E-cadherin expressions and tumor stage and prognosis in pancreatic cancer. Method EphA2, EphrinAl and Ecadherin expressions were detected by immunohistochemistry in the tumor tissue and normal tissue specimens from 48 patients with primary pancreatic cancer. Results The expressions of EphA2 and EphrinAl were higher in the pancreatic carcinoma tissues than in the normal pancreatic tissues (P<0. 05). The E-cadherin expression was lower in the pancreatic cancer tissues than in the normal pancreatic tissues (P<0. 05). With decreasing histological differentiation, the expressions of EphA2 and EphrinAl in carcinoma tissues increased significantly (P<0. 05), while the E-cadherin expression decreased significantly (P<0. 05). The positive expressions of EphA2 and EphrinAl in the primary tumor significantly increased in stageⅢ and Ⅳ than in stage Ⅰ and Ⅱ (47. 9%vs 6. 25% , P<0. 05;47. 9% vs 8. 3%, P<0. 05), while the negative expression of E-cadherin was reversely correlated with these tumor stages (14. 6% vs 64. 6%, P<0. 05). Cox multivariate analysis showed that the clinical stage, EphA2 positive expression and E-cadherin negative expression were significantly associated with survival. Conclusion Abnormal expressions of EphA2, EphrinAl and E-cadherin were involved in the progression of pancreatic cancer and they were useful in predicting prognosis.

Objective To investigate the prognostic value of vascular endothelial growth factor C (VEGF-C) and clinicopathologic indexes in predicting recurrence following curative resection of pancreatic cancer. Methods The expressions of VEGF-C of 47 patients who underwent curative resection for curative pancreatic cancer resection were detected by Envision immunohistochemical methods. The effects of VEGF-C and clinicopathologic indexes on recurrence were assessed by the Kaplan-Meier and Cox proportional hazards model. Results The positive rates of VEGF-C were 61. 7% in = 29) and 14. 9%(n = 7), respectively, in pancreatic cancer and normal pancreatic tissues. The positive expression of VEGF-C in pancreatic carcinoma was obviously higher than the normal pancreatic tissues (P = 0. 018). The median disease-free survival time was 11. 9 months, the average disease-free survival time was 18. 4 + 2. 4 months, and the cumulative 1-year, 2-year and 3-year actuarial recurrence free survival rates were 46. 8%, 23. 4%, 14. 4%, respectively. There was a significant correlation between the VEGF-C expression and lymph node metastasis in pancreatic cancer (P = 0. 036). On Kaplan-Meier analysis, VEGF-C (P = 0. 020), tumor diameter (P = 0. 013), age (P = 0. 057) and adjuvant chemotherapy (P=0. 017) were associated with disease-free survival time. Multivariate analysis showed VEGF-C (P = 0. 009), tumor diameter (P = 0. 010) and adjuvant chemotherapy (P = 0. 017)were independent prognostic factors of disease-free survival after surgery for pancreatic cancer.Conclusion The expression of VEGF-C was higher in pancreatic cancer, and VEGF-C was correlated with lymph node metastasis. VEGF-C was the biomarker that independently predicted disease-free survival after surgery for pancreatic cancer.

ObjectiveTo investigate the change of gene polymorphorism of surfactant protein-B (SP-B) intron 4 in infants with bronchopulmonary dysplasia (BPD).MethodsForty-five infants with BPD (BPD group) and ninety-nine infants without lung diseases (control group) who admitted into Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from July 2008 to July 2011 were selected into this study.Genotyping for fragment length polymorphism of SP-B intron 4 was performed by polymerase chain reaction (PCR),agarose gel electrophoresis,cloning and sequencing methods in both groups.Differences of allele frequencies (invariant allele and variant allele) and genotype frequencies (invariant genotype and variant genotype) between BPD group and control group were analyzed.The differences of gestational age and birth weight between the two groups were compared with Independent-Samples t test.The gender composition and differences of allele or genotype frequencies between the two groups were compared with Chi-square test.Results Invariant allele frequencies in BPD group and control group were 83.3％ (75/90) and 92.0％ (182/198),and variant allele frequencies were 16.7％ (15/90,including eight insertion alleles and seven deletion alleles) and 8.1％ (16/198,including eight insertion alleles and eight deletion alleles).There were significant differences between the two groups (x2 =4.75,P =0.029).In BPD group,there were 32 cases (71.1 ％,32/45) invariant genotypes and 13 cases (28.9 ％,13/45,including seven cases insertions and six cases deletions) variant genotypes; in the control group,there were 85 cases invariant genotypes (85.8％,85/99) and 14 cases (14.1％,14/99,six insertions and eight deletions) variant genotypes.Significant difference was found between the two groups (x2=4.42,P＜0.036). ConclusionsVariations of SP-B intron 4 were more in BPD infants,and the variation of SP-B intron 4 might be associated with BPD.
