It is still controversial whether or not the severe pneumonia is associated with heart failure in children.Currently,we pay more attention to the pathophysiological procedure of heart failure,such as pneumonia complicated with respiratory failure,shock and myocardial injury.Pay attention to the cardiopulmonary interaction mechanism and systemic inflammatory response.According to different pathophysiological mechanisms,guide the treatment by monitoring the hemodynamic status.

[Summary]_ Severe hypertriglyceridemia is the third common cause of acute pancreatitis following after alcohol abuse and cholelithiasis. Moreover, it is also an important risk factor of cardiovascular events. However, the cases of severe hypertriglyceridemia caused by autoimmune disease were rare in clinical, which would bring the difficulty for diagnosis and treatment. A better understanding of the clinical characteristics, possible pathogenesis, and corresponding therapy of the disease would be helpful, which would reduce the risk of complications, and finally improve both the survival rate as well as quality of life of these patients.

BACKGROUND: Biomechanical mechanisms are complex, and previous studiers focus on the stress conduction in the carpus. However, the stress distribution and characteristics of trabecula in the carpus are rarely reported.OBJECTIVE: To investigate the stress distribution and deformation characteristics of the normal lunate through a two-dimensional sagittal finite element model.METHODS: A normal cadaveric lunate sample was scanned with Micro-CT and the central sagittal image was chosen for further finite element analysis (FEA). The chosen image was processed and imported into the finite element analysis software (Ansys 14.0). A two-dimensional sagittal finite element model of the lunate bone was established. Axial pressure was applied to the model with the wrist held in different positions, and nine regions of interests (ROIs) were identified, for which stress and displacement nephograms were created. These included the first principal stress (S1, the maximum stress in a principal plane), the third principal stress (S3, the minimal stress in a principal plane), shear stress (SXY, the component of stress coplanar with a material cross section), von Mises stress (SEQV, yielding begins when the elastic energy of distortion reaches a critical value)and displacement of each ROI (UY, displacement on the vertical plane of the lunate) which were calculated and compared.RESULTS AND CONCLUSION: (1) The stresses on ROIs located in the proximal and volar cortices of the lunate bone were much higher than those in the distal and dorsal cortices. At the proximal lunate, S1 was less than S3; however at the distal lunate, S1 was greater than S3. The ROIs of the distal and proximal ends of the lunate bone received much higher stress than the ROIs of the middle part. As for axial trabecular displacement,both distal and proximal ROIs were compressed by axial pressure. However, the dorsal and the volar parts of the proximal lunate moved in different directions at different wrist postures. Besides, the stress values and magnitudes of displacement were elevated in wrist flexion and extension compared to neutral position.Furthermore, the stress concentration zones (the proximal volar ROI, the proximal dorsal ROI, the distal volar ROI, and the distal dorsal ROI) had different directions of shear stress and displacement in different wrist postures. (2) These results suggest that when stress is loaded on a normal lunate model, four stress concentration zones, the proximal volar ROI, the proximal dorsal ROI, the distal volar ROI, and the distal dorsal ROI are found. The wrist postures can significantly affect the value and distribution of axial stress on the sagittal lunate.

Objective Hermaphroditic planarians possess a very important position in the systematic evolutionary history of animal, as they are capacity of complete regeneration. Hence, the research on histological structure of autofluorescence has been carried out to provide a crucial insight into the developmental and regenerative biology. Methods Part of histological structure of planarian (Dugesia japonica) was revealed with HE method, Masson method and Van Gieson method. Their autofluorescence was observed with ultraviolet. There were six planarians in each stained group and the autofluorescence group. Results Epidermis, outer epidermis of pharynx, protonephridium, intestine, the photoreceptor cells and longitudinal nerve cords, all radiated blue autofluorescence. The epithelial dissociation side of copulatory bursa radiated yellow autofluorescence, its middle part radiated blue autofluorescence, its fundus side radiated weakly blue autofluorescence. Testis could hardly give off autofluorescence. Pigment cells of eyepot could not give off autofluorescence. Conclusion The research on configuration and autofluorescence of planarian eye may offer help for the study of origin and evolutionary law on eye of invertebrate.

Objective To evaluate the value of real-time three-dimensional echocardiography（RT3DE）to predict the long-term response to cardiac resynchronization therapy（CRT）.Methods Twenty-six patients with heart failure were scheduled for CRT.RT3DE was performed before and one year after the pacemaker implantation,and left ventricular（LV）dyssynchrony was defined as the maximum difference（Tmsv 16-Dif）and standard deviation（Tmsv 16-SD）when the minimum systolic volume of 16 segments was reached.Patients were divided into re-sponders and non-responders according to a reduction ≥15 % in LV end-systolic volume（LVESV）after CRT.Results Seventeen patients（65.4 %）were classified as responders.Compared with non-responders,the responders demonstrated a significant increase in LV ejection fraction,and reduction in Tmsv 16-SD.Tmsv 16-SD was a determinant factor for Δ LVESV ≥15%.Tmsv 16-SD 〉3.5% could be employed to evaluate the short-term response to CRT with 80 % sensitivity and 77 % specificity.Conclusions CRT can increase the LV systolic function and synchrony.RT3DE is highly predictive for long-term response to CRT

[Summary] In newly diagnosed diabetic patients, fasting plasma glucose, HbA1C , and plasma lipid profiles were measured to analyze the association between HbA1C and plasma lipid profiles. HbA1C might affect plasma lipid profiles in newly diagnosed diabetic patients. Higher HbA1C was associated with the worse plasma lipid profiles and more severe insulin resistance.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.

Objective To assess the value of two-dimensional speckle tracking echocardiography (2D-STE) of predicting the acute response to cardiac resynchronization therapy (CRT) in patients with congestive heart failure. Methods Twenty-four patients with congestive heart failure scheduled for CRT were included. 2D-STE was performed within 7 days of implantation with device ON and OFF. Left ventricular (LV) dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (T_(AS-POST)) with 2D-STE. Acute hemodynamic response was measured as LVdp/dt, and percentage change in LVdp/dt was used to classify responders (Δdp/dt%＞25%) and nonresponders (Δdp/dt%≤25%). Results Fifteen patients (62.50%) were classified as acute responders. Compared with nonresponders, the responders demonstrated significant increase of LV ejection fraction and reduction of TAS-POST after CRT-ON. T_(AS-POST)was the only determinants of Δdp/dt%＞25%. T_(AS-POST)≥130 ms prognosticated acute response to CRT with sensitivity of 86.24% and specificity of 70.38%. Conclusion CRT can immediately increase the LV systolic function and synchrony. 2D-STE is highly predictive for acute response to CRT.
