Objective To investigate the relationship between thyroid hormone levels and the attack of arrhythmia after thoracic surgery.Methods Information of 44 patients after thoracic surgery form September 2012 to February 2015 in General Hospital of Tianjin Medical University was collected, and divided in to the arrhythmia group and non-arrhythmia group.A retrospective analysis was carried on their ECG, thyroid hormone levels, and physical health, and the parameters were then compared between the two groups.The correlation of triiodothyronine (T3) level and Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) was analyzed.Results The arrhymia patients' serum T3 and free triiodothyronine (FT3) levels were below normal levels, while the serum T3 and FT3 levels of the non-arrhythmia patients were within normal range, and the differences between the two groups were significant (P<0.05).No notable change of other thyroid hormones levels and correlation of T3, FT3 and APACHE Ⅱ score were found.Conclusions There is a significant difference between the arrhythmia and non-arrhythmia groups in serum T3 and FT3 levels.Perioperative thyroid hormone replacement therapy is worthy of consideration and trial in the clinical prevention and treatment of arrhythmia and prognostic improvement of patients.

Objective Evaluation of left ventricular ( LV) function has great clinical significance in patients with early chro-nic kidney disease (CKD).The study was to evaluate whether two-dimensional speckle tracking imaging (2D-STI) technique can offer additional information of cardiac dysfunction in early CKD patients . Methods Conventional echocardiography and 2D-STI echocar-diography were performed in CKD group of 20 patients at stage Ⅱ-Ⅲ and control group of 20 healthy volunteers .LV structure and function were evaluated by conventional echocardiography .Multidirectional strain , strain rate and LV twist parameters were analyzed by 2D-STI technique. Results There was no statistical difference in conventional echocardiographic parameters such as left atrial diam -eter, end-diastolic LV diameter and ejection fraction between CKD group and control group .By applying 2D-STI technique, CKD group had significantly decreased value of global longitudinal strain (-19.8 ±2.4)%and strain rate(-1.1 ±0.3)S-1 in comparison to control group(-22.6 ±2.1)%、( -1.8 ±0.2)S-1, along with significant increase in the values of maximum LV rotation (11.6 ± 4.4)°and LV twist(19.6 ±3.8)°in comparison to control group(8.2 ±3.7)°、(13.5 ±3.6)°(P<0.05).There was no differences in both global circumferential and radial deformation parameters as well as maximum rotation value of LV assist device between two groups(P>0.05). Conclusion 2D-STI can detect subclinical LV dysfunction sensitively in early CKD patients .

Objective To evaluate the utility of flow cytometry (FCM) in diagnosis and subclassification of non-Hodgkin lymphoma (NHL). Methods The samples of lymph nodes biopsy from 59 cases clinically suspected of NHL were detected by flow cytometry; and clonal lymphocytes and their immunophenotypes were identified analyzed. The concordance between the results of flow cytometry and histopathology was analyzed. Results Among the 59 cases, flow cytometry was able to identify aberrant clonal lymphocytes in 24 of 28 NHL cases identified by histopathology, the neoplastic lymphocytes ranged from 4.28 % to 89.10 %; 23 cases were diagnosed as B-NHL and 1 case was diagnosed as T-NHL. Compared with histopathology, the accuracy of FCM was 85.71% in diagnosis of NHL. The specificity and sensitivity of FCM was 100 % and 92% in diagnosis of B-NHL. The accuracy of flow cytometry immunophenotyping in classification of 24 cases of NHL was consistent with that of histopathology. Conclusion Flow cytometry could be an ancillary technique in diagnosis of NHL by identifying aberrant clonal lymphocytes, and enable identification of B-NHL subtype.

Objective To explore the role and their relationship of Ki-67, VEGF and p27 expressed in adult patients with acute leukemia. Methods The expression of Ki-67, VEGF and p27 in bone marrow mononuclear cells (BMMNC) were analyzed by immunocytochemical staining, and their correlations of Ki-67, VEGF and p27 were statistically analyzed. Results The expression of Ki-67(42.48±25.78)% or VEGF (44.89±24.01)% on BMMNC from acute leukemia cells was significantly higher than that in the control (11.40±9.94)% or (16.90±12.54)% (P<0.01). But the expression of p27 (23.65±13.30)% was significantly lower than that in the control (50.23±22.68)% (P<0.01). The expressions of Ki-67 were positively correlated with and VEGF in patients with acute leukemia were positively correlated(r=-0.666, P<0.01), and the expressions of Ki-67 and p27 were negatively correlated with p27 in patients with acute leukemia (r=-0.316, P<0.05).Conclusion The evaluation of expression of Ki-67, VEGF and p27 on acute leukemic cells provides new insights to the pathogenesis is helpful in mechanism and is helpful in the diagnosis of acute leukemia.

Objective To study the effects of semiconductor laser irradiation and high voltage static electric fields on small vessel damage in diabetic rats.Methods Fifty healthy male Wistar rats were randomly divided into two groups:8 rats in a normal group and 42 in a diabetic model group.The diabetic models were created by intrape- ritoneal injection of streptozocin.The diabetic model rats were randomly divided into four subgroups:a diabetes group,a semiconductor laser treatment group,a high voltage static electric field treatment group and a comprehensive treatment group receiving combined semiconductor laser and high voltage static electric field exposure.The rats in each treatment group were subjected to the corresponding intervention.After 20 days of treatment,the venous blood, kidney tissue and myocardium tissue of the rats were collected,and the concentrations of blood glucose,insulin,en- dothelin and tissue were detected.Results Compared with the normal group,a significant increase in blood glu- cose and endothelin was observed in the diabetic model group,along with significantly decreased blood insulin and significant small vessel endothelium proliferation in the kidney tissue.Compared with the diabetes group,endothelin levels were significantly lower in all 3 treatment groups,and blood insulin was also higher in the comprehensive treat- ment group.Conclusion There were severe abnormalities in blood glucose,insulin and endothelin as well as mild impairment of small vessel endothelium proliferation in the diabetic rats.Semiconductor laser and high voltage static electric field exposure have a role in treating and preventing these conditions in diabetic rats.

Objective To observe the effect of ultrashort wave diathermy on collagen type I expression in early stage of hormon-induced avascular necrosis of the femoral head (ANFH) in rabbit.Methods A total of 40 New Zealand white rabbits were randomly divided into two groups:a control group (n=10) and a treatment group (n =30).All the animals in the treatment group were injected with horse serum and methylprednisolone to establish the ANFH model,and then divided into 2 subgroups:a model group and a ultrashort wave diathermy group,which were treated accordingly.After 12 weeks of treatment,all the animals were sacrificed and collagen type I expression in the femoral head was observed.Results It was shown that the expression of the collagen type I was significantly lower in the model animals than that in the controls as indicated by the stronger immunohistochemistry staining for rabbit collagen type,while that of the ultrashort wave diathermy group was significant higher than the control group ( P

Objective To investigate the source of the blood flow through ventricular septum in normal subject caused by slice-thickness artifact in echocardiography. Methods Echocardiography was performed in 50 normal subjects without ventricular septum defect by two models of echocardiography unit equipped with two models of transducer, observing the conditions and sections in which the blood flow through ventricular septum could be detected. Results The blood flow through ventricular septum was detected in 8 normal subjects using the certain model of echocardiography unit,especially in parasternal four chambers section and parasternal irregular sections, while the blood flow through ventricular septum wasn't detected in the other 42 subjects by any echocardiography unit. The blood flow through ventricular septum was caused by coronary vessel in atrioventrieular groove proved by combining dynamic observation with anatomy analysis. Conclusions The blood flow through ventricular septum in normal subjects, a kind of slice-thickness artifact in echocardiography,is caused by coronary vessel in atrioventricular groove mapped into intact ventricular septum.
