ObjectiveTo analyze the risk factors of pulmonary infection for critically ill ICU patients with tracheotomy,and investigate the methods to prevent nosocomial lung infection. Methods94 patients in ICU with pulmonary infection after tracheotomy from March 2008 to March 2010 were analyzed retrospectively,they were set as the observation group.100 patients in synchronization without pulmonary infection after tracheotomy were set as the control group.The general condition,diagnosis and treatment methods and care,the environment,etc.were studied,the risk factors for nosocomial pulmonary infections after tracheotomy were analyzed.The care methods and points to prevent lung infections for critically ill ICU patients after tracheotomy were summarized. ResultsThe study showed that the respiratory system diseases in critically ill patients,smoking history,low seniority of nursing staff,long-term use of large dose of antibiotics,application of H2 blockers and antacids,and many patients in the same ward were risk factors for critically ill patients with pulmonary infection. ConclusionsLung infection after tracheotomy in critically ill ICU patients was affected by many factors.In the actual operation,we should targeted to avoid infection led by treatment and care factors,environmental factors,control and prevention measures should especially be strengthened for patients with respiratory diseases to prevent lung infection.

In this study we performed Tissue Doppler Imaging (TDI), two-dimensional speckle tracking imaging (2D- STI) and three-dimensional speckle tracking imaging (3D-STI) on enrolled healthy, overweight and obese groups (34 subjects in each group), respectively, to analyze cardiac structure and its function. Compared with healthy group, global longitudinal strain (GLS), global circumferential strain (GCS), global area strain(GAS) and global radial strain (GRS) decreased progressively (P < 0.05). The ratio of early diastolic mitral inflow velocity to global early diastolic strain rate of left ventricle (E/e'sr) (r = 0.466, P < 0.001), GLS (r = 0.502, P < 0. 001), GCS (r = 0.426, P < 0.001), GAS (r = 0.535, P < 0.001) and GRS (r = -0.554, P < 0.001) were correlated with body mass index (BMI). E/e'sr (r = 0.37, P = 0.003), GLS (r = 0.455, P < 0.001), GCS (r = 0.282, P = 0.02), GAS (r = 0.412, P < 0.001) and GRS (r = -0.471, P < 0.001) were correlated with free fatty acid (FFA). Stepwise multiple linear regression revealed that BMI was independently correlated with E/e'sr, GLS, GCS, GAS and GRS. Waist to hip ratio (WHR) was independently correlated with GLS, GCS, GAS and GRS. FFA was independently correlated with E/e'sr (P < 0.05). The study showed that cardiac structure changed and impaired left ventricular global systolic and diastolic function in overweight and obes population. Moreover, BMI, WHR and FFA may be independent influence factors of cardiac function in overweight and obese population.

An electrolyte cathode atmospheric glow discharge atomic emission spectroscopy(ELCAD-AES) has been developed to determine the hardness of water. By the standard curves of Mg and Ca, the concentration curves of Mg and Ca measurement were obtained. The limits of detection of Mg and Ca were 0.2 and 0.8 mg/L, respectively. The precision and recovery were experimentally elucidated, which indicated that the homemade ELCAD-AES system has a good performance. Finally, practical water samples such as tap water, boiled tap water, ground water, boiled ground water and lake water were analyzed by the method. The results were in agreement with those by the EDTA titration. This demonstrates that ELCAD-AES has the capacity for on-line determination of water hardness.

Objective To observe the effects of interleukin-1β (IL-1β) and pentylenetetrazol (PTZ) induced acute epilepsy and the dynamic expression of aquaporin-4 (AQP4) in hippocampus. To explore the role of IL-1β in the pathogenesis of epilepsy by regulating AQP4. Methods All rats were randomly divided into control group, IL-1β group, PTZ group, IL-1ra + PTZ group and dexamethasone + PTZ group. Observe the behavior of the rats within 60 minutes after injection and record seizure score in each group. Then immunohistochemistry and RT-qPCR were used to detect the expression of AQP4 at at 6 , 12, 24 and 36 h. Results Almost of rats in IL-1β group and PTZ group showed severe degree seizure. The rats in control group and dexamethasone + PTZ group showed no obvious seizure. The seizure of rats were more remarkable serious in PTZ group than that in the IL-1ra + pentylenetetrazole group (P < 0.05). Immunohistochemistry and RT-qPCR Show: the expression of AQP4 in hippocampus in PTZ group increased gradually after 12 h (P < 0.05), then reached in the peak after 24 h (P < 0.001). The expression of AQP4 in IL-1ra + PTZ group was lower compare with PTZ group in each time (P < 0.05). Although the expression of AQP4 in dexamethasone + PTZ group higher than the control group, it was not significantly different (P < 0.05). Conclusion The proinflammatory cytokine IL-1β break the balance of water in brain and increasing the concentration of extracellular excitatory amino acids or ions by upregulate the expression of AQP4 in order to promote the excitatory of neurons.

Objective The purpose of this study was to discuss the clinical significance of serum levels of Pro-gastrin-releasing peptide (ProGRP) in diagnosis,therapy monitoring and prognosis in patients with small cell lung cancer (SCLC).Methods Clinical diagnostic trial.Serum levels of ProGRP were measured by ELISA assays in 413 SCLC patients,418 NSCLC,120 with benign pulmonary diseases patients and 200 healthy subjects.Patients were recuited by the Shanxi Cancer Hospital from Dec.2005 to Oct.2008.Three hundreds and sixty-eight patients with SCLC were followed up from Dec.2005 to Oct.2011.The receiver operating characteristic curves (ROC) was used to set the cut-off value of ProGRP and the area under ROC (ROC-AUC).The sensitivity and specificity of ProGRP were analyzed for diagnosing SCLC.The survival analysis was performed by the Kaplan-Meier method and Cox's proportional hazards model for multivariate analysis of prognosis.Results Using healthy subjects group as control,the largest Youden index point of ROC was used to set the cut-off values of ProGRP and NSE (45.3 ng/L and 12.4 ng/L).The ROC-AUC of ProGRP was 0.798 (95％ CI:0.746-0.850)the sensitivity and specificity were 79.2％,98.1％ respectively.The AUC of NSE was 0.786(95％ CI:0.726-0.746),the sensitivity and specificity were 71.9％,96.7％ respectively; Combing detection of ProGRP and NSE,the sensitivity and specificity were 88.1％,95.8％ respectively.Serum levels of ProGRP in healthy subjects,benign pulmonary diseases,NSCLC and SCLC groups were 6.9 (5.3-8.6),36.8 (26.3-43.4),21.3 (18.6-35.2) and 1758.7 (368.4-2967.3) μg/L respectively.The serum levels of ProGRP in SCLC groups were significantly higher than those in the healthy group,benign pulmonary diseases group and NSCLC group (H =103.66,P =0.000).Serum levels of ProGRP in SCLC at stage Ⅰ-],stage m,stage Ⅳ were 543.3 (256.8-843.2),1440.6 (1042.4-2543.3) and 1897.6 (1586.5-3958.7) μg/L,respectively (H =25.974,P =0.000).Serum levels of ProGRP in 165 SCLC patients with complete remission(CR) were significantly declined after treatment (U =11.65,P ＜ 0.01).The levels of ProGRP in 146 SCLC patients with partial remission(PR) slowly decreased (U =9.17,P ＜ 0.01).Thirty-nine cases with progressive disease (PD)and 63 cases with stable disease(SD) presented elevated ProGRP levels (U =3.314,P ＜ 0.001 ; U =2.54,P ＜ 0.01,respectively).By the end of October 31st 2011,a total of 368 cases with SCLC were followedup.Ratio of follow-up was 89.1％.There were 56 deaths in 119 SCLC patients with ProGRP ＜ 1000 μg/L (median time =16.0 months,4-23 months) ; 159 deaths in 249 with ProGRP ＞ 1000 μg/L (median survival time =12.0 months,2-18 months).Median survival time of the two groups showed significant differences(x2 =11.04,P =0.001).Multivariate analysis by Cox's proportional hazards model revealed that ProGRP was independent prognostic factor related to the overall survival (OS) of SCLC patients.Conclusions The serum ProGRP is valuable tumor marker for diagnosis,treat monitoring and prognosis of SCLC.It's important to predict relapses and recurrence of diseases earlier,instruct therapy and prognosis assessment.
