Aim To establish a simple, rapid and accurate electroanalytical method for water soluble porphyrin meso-tetrakis-(4-sulfonatophenyl) porphyrin (TPPS4);to clarify the reaction between water soluble porphyrins and bovine serum albumin (BSA);and to determine the interaction of TPPS4 with BSA in the absence of presence of cyclodextrins (CDs) , separately. Methods Three methods including LSV,UV spectroscopy and fluorescence spectroscopy bad been employed to the relevant experiments. The way of employing three methods at the same time could make the experiment results more reliable. Results In the supporting electrolyte of NaH2 PO4-Na2 HPO4 ( pH 7. 18 ), a sensitive reduction peak of TPPS4 was found by linear sweep voltammetry (LSV), the peak potential (Ep) was-0. 70 V (vs SCE). The relationship between the second derivative peak of LSV (ip") and the concentration of TPPS4 was linear from 1.0 × 10-7mol·L-1 to 1.0 × 10-5mol· L-1,the square of correlation coefficients (r2) were 0. 998 3 and 0. 999 3, respectively. The relative standard deviation (RSD) was 0. 56% ( n = 5 ). The mean recovery of TPPS4 was 99.59%. In NH4C1-NH3· H2O buffers (pH 9.05), it was proved that BSA and TPPS4 could interact with each other and form 1:1 TPPS4-BSA supramolecular system. Moreover, the interaction between TPPS4 and BSA had been investigated by adding cyclodextrins (CDs). The interaction of TPPS4 with BSA was facilitated both by hydroxypropyl-β-CD (HP-3-CD) and sulforbutylether-β-CD (SBE-3-CD). Conclusion An electroanalytical method for TPPS4 has been established by LSV. The porphyrin drugs included by CDs could react with protein existing inside the human body easier. The consequences of this article also show that CDs will play important role in controlling and releasing the porphyrin drugs.

Objective: To summarize the major post-operative complication of modiifed extended Morrow procedure in patients with hypertrophic obstructive cardiomyopathy (HOCM) and to explore the major factors affecting its prognosis. Methods: We retrospectively analyzed 139 consecutive HOCM patients who received the procedure by same surgeon in our hospital from 2012-06 to 2014-07. There were 87 male and 52 female patients with the age of (10-67) years, body weightof (26-105) kg and pre-operative left ventricular outlfow tract peak gradient (LVOTPG) of (84.48 ± 44.75) mmHg. Concomitant operations were performed with known cardiac disease as necessary. Pre- and post-operative echocardiography, ECG and chest X-ray were examined to assess the adequacy of resection and mitral valve structure and function. Results: There was no peri-operative death. 73/139 (53%) patients received simple modiifed expanded Morrow procedure, the other 66 (47%) patients received concomitant surgery including 21 patients with coronary artery bypass grafting, 15 mitral valve plasty, 7 mitral valve replacement, 10 tricuspid valve plasty, 2 aortic valve replacement, 3 modiifed Maze procedure, 2 unblock of right ventricular outlfow tract, 2 sub aortic membrane resection, 1 ventricular aneurysm resection. The mechanical ventilation time was (24.05±36.74) hours, post-operative ICU and in-hospital stays were (2.85±3.18) days and (10.11±4.57) days; the complications included arrhythmia in 108 cases, pleural effusion in 25 cases, secondary intubation in 1 case, tracheotomy in 1 case, hemoifltration in 1 case, intra-aortic balloon pump in 1 case, back into ICU in 3 cases; no pneumothorax, secondary thoracotomy/operation. The post-operative left atrial diameter, LVOTPG, inter-ventricular septal thickness and LVEF were all decreased; mitral valve closed well or with mild regurgitation, systolic anterior motion (SAM) basically disappeared. The major factors for delayed ICU stay included age≥55 years, female, CPB time≥120 min, AOC time≥90 min, the patients combining with arrhythmia and right ventricular dysfunction. Late follow-up presented that the patients were almost without the symptoms, NYHA classiifcation at (I-II), no late death, complication or re-operation. Conclusion: Modified expand Morrow procedure has good surgical and short/late post-operative effects, concomitant operation does not increase the complication and mortality; correction of arrhythmia and improving right ventricular function at peri-operative period are important for treating the relevant patients.

This study described the radiological features on echocardiography and MRI specific to cardiac amyloidosis confirmed on biopsy. Eleven cases of biopsy-proven cardiac amyloidosis were retrospectively reviewed in this study. All patients underwent biopsy, cardiac MRI and echocardiography. The main echocardiography and MRI findings were as follows: diffuse ventricular and septum wall thickening, atrial enlargement, pericardial effusion, restricted left ventricular (LV) systolic and diastolic function, characteristic granular sparkling of myocardium. MRI revealed a characteristic pattern of global subendocardial late enhancement, extending in varying degrees into the neighboring myocardium. The findings agreed with the infiltration distribution of amyloid protein. Typical abnormalities seen on echocardiography and MRI should have important diagnostic and prognostic value of cardiac amyloidosis. MRI should be considered in the diagnosis of cardiac amyloidosis if echocardiographic features are suspicious.

Objective To investigate the value of bedside lung ultrasound B-line score in the diagnosis of acute heart failure (AHF). Methods A retrospectively analysis was conducted. The adult patients presenting with acute dyspnea in intensive care unit (ICU) of Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from January 2016 to June 2017 were enrolled. An 8-zone lung ultrasound was performed and plasma B-type natriuretic peptide (BNP) level was tested in all patients. AHF was determined as the final diagnosis by two experienced ICU doctors according to the diagnostic criteria of AHF. Patients were divided into two groups: AHF group and non-AHF group. The levels of BNP and B-line score were compared between the two groups, and the diagnostic value of BNP and B-line score in AHF was evaluated. Results Fifty-six patients were included in this study, with 32 of men and 24 of women,and with an average age of 77.3±8.8. Thirty-six patients were diagnosed as AHF. The level of BNP and lung ultrasound B-line score in AHF group were higher than those in non-AHF group [BNP (ng/L): 1 640.4±1 078.4 vs. 236.9±124.9,B line score: 12.8±5.3 vs. 5.4±1.8, both 1 < 0.01]. There was a strong correlation between elevated BNP levels and an increased B-lines score (R2 = 0.712, 1 = 0.000). The receiver operating characteristic curve (ROC) showed that when the cut-off of lung ultrasound B-line score was 8.5, AHF could be discriminated from dyspnea caused by other diseases (sensitivity was 77.8%, specificity was 95%, positive likelihood ratio was 15.56, negative likelihood ratio was 0.23).The area under the ROC curve (AUC) of lung ultrasound B-line score was 0.917 [95% confidence interval (95%CI) =0.847-0.987, 1 = 0.000], slightly lower than that of plasma BNP [0.979 (95%CI = 0.951-1.008)]. Conclusion Lung ultrasound B-line score was highly specific, but moderately sensitive for identifying patients with AHF.

Objective:To investigate the significance of changes of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in neoadjuvant therapy for rectal cancer.Methods:The data of 86 patients with rectal cancer who received neoadjuvant therapy from November 2013 to January 2015 in Shanxi Provincial Cancer Hospital were retrospectively analyzed, and the correlations of NLR and PLR changes with the patients' clinicopathological characteristics and therapeutic effects were also analyzed.Results:There were 43 cases of increased NLR and 43 cases of increased PLR after treatment. NLR and PLR changes before and after neoadjuvant therapy in patients with rectal cancer were not associated with age, gender, TNM stage, lymph node metastasis, number of cancer nodules, and tumor diameter (all P > 0.05). The increasing proportion of NLR and PLR after treatment in patients with the distance from the tumor to anus < 6 cm was higher than that in those with the distance≥6 cm [60.00% (30/50) vs. 36. 11% (13/36), χ2 = 4.778, P = 0.029; 64.00% (32/50) vs. 30.56% (11/36), χ2 = 9.364, P = 0.002]. The increasing proportion of NLR and PLR after treatment in patients with the body mass index (BMI) ≥28 kg/m 2 was higher than that in those with BMI < 28 kg/m 2 [81.82% (9/11) vs. 45.33% (34/75), χ2 = 5.108, P = 0.024; 90.91% (10/11) vs. 44.00% (33/75), χ2 = 8.444, P = 0.004]. The remission rate of patients in NLR reduction group after treatment was higher than that in NLR increase group [72.09% (31/43) vs. 51.16% (31/43), χ2 = 3.983, P = 0.046]. PLR changes were not associated with the therapeutic effects of neoadjuvant therapy before and after treatment ( P > 0.05).

Hepatocellular carcinoma (HCC) is the most common pathological type of primary liver cancer, with high fatality rate. The pathogenesis of HCC is complex, and the specific occurrence and development mechanism is still in the exploratory stage. CircRNA is a special endogenous noncoding RNA and mainly participates in the regulation of gene expression at the transcriptional and posttranscriptional levels. By regulating gene transcription, it acts as a molecular sponge of miRNA, participates in protein translation, and interacts with RNA binding protein (RBP). CircRNA is involved in the occurrence and development of HCC. Its abnormal expression in HCC cells is related to the pathological characteristics of HCC tissue, regulates the expression of downstream target genes, miRNA and proteins, participates in the proliferation, migration, invasion and apoptosis of HCC cells, and regulates tumor microenvironment and signal pathways, suggesting that circRNA may be a potential novel biomarker and therapeutic target for the diagnosis and prognosis of HCC. This paper reviews the biological mechanism of circRNA, its role in HCC, and research progress in diagnosis and treatment.
