N-terminal pro-B-type natriuretic peptide as a marker of blunt cardiac contusion in trauma.
Cardiac contusion is usually caused by blunt chest trauma and, although it is potentially a life-threatening condition, the diagnosis of a myocardial contusion is difficult because of non-specific symptoms and the lack of an ideal test to detect myocardial damage. Cardiac enzymes, such as creatine kinase (CK), creatine kinase MB fraction (CK-MB), cardiac troponin I (cTn-I), and cardiac troponin T (cTn-T) were used in previous studies to demonstrate the blunt cardiac contusion (BCC). Each of these diagnostic tests alone is not effective for diagnosis of BCC. ⋯ A relation between NT-Pro BNP and BCC was shown in this study. Serum NT-proBNP levels significantly increased with BCC after 5 hours of the blunt chest trauma. The use of NT-proBNP as an adjunct to other diagnostic tests, such as troponins, electrocardiography (ECG), chest x-ray and echocardiogram may be beneficial for diagnosis of BCC.

Morphological changes in the sciatic nerve, skeletal muscle, heart and brain of rabbits receiving continuous sciatic nerve block with 0.2% ropivacaine.
To investigate the morphological changes in various tissues of rabbits receiving sciatic nerve block with 0.2% ropivacaine for 48 h. ⋯ Pyknotic degeneration of sciatic nerve increased after an infusion of 0.2% ropivacaine hydrochloride for 48 h, suggesting the neurotoxicity of ropivacaine. An infusion of 0.2% ropivacaine hydrochloride for 48 h may cause necrosis of skeletal muscle cells. The sciatic nerve edema would greatly affect the hindlimb motor while both pyknotic degeneration of sciatic nerve and skeletal muscle have little influence on the hindlimb movement. After an infusion of 0.2% ropivacaine hydrochloride for 48 h, the morphology of right atrium and brain tissues around the ventriculus tertius and medulla oblongata remained unchanged.

Papillary renal cell carcinoma: a clinicopathological and whole-genome exon sequencing study.
Papillary renal cell carcinoma (PRCC) represents the second most common histological subtype of RCC, and comprises 2 subtypes. Prognosis for type 1 PRCC is relatively good, whereas type 2 PRCC is associated with poor clinical outcomes. The aim of the present study was to evaluate the clinicopathological and mutations characteristics of PRCC. ⋯ Associated pathways included the ATP-binding cassette transporter, extracellular matrix-receptor interaction, lysosome, complement and coagulation cascades, and glyoxylate and dicarboxylate metabolism pathways. The missense mutation status of 19 genes differed significantly between the groups (P < 0.05), and alterations in the EEF1D, RFNG, GPR142, and RAB37 genes were located in different chromosomal regions in type 1 and 2 PRCC. These mutations may contribute to future studies on pathogenic mechanisms and targeted therapy of PRCC.

Matrine inhibited proliferation and increased apoptosis in human breast cancer MCF-7 cells via upregulation of Bax and downregulation of Bcl-2.
The aim of the present study was to investigate the effects of matrine on proliferation and apoptosis in human breast cancer MCF-7 cells and its relevant molecular mechanisms. ⋯ Matrine significantly inhibited the growth and induced apoptosis in breast carcinoma MCF-7 cells, which is related to Bax, Bcl-2 signaling and MMP.

Prognostic significance of preoperative C-reactive protein: albumin ratio in patients with clear cell renal cell carcinoma.
We undertook a retrospective analysis to evaluate the C-reactive protein/albumin (CRP/Alb) ratio for its prognostic value in patients with clear cell renal cell carcinoma (CCRCC). The study comprised 406 CCRCC patients undergoing nephrectomy between 2003 and 2012 in our hospital. The correlations among the pretreatment CRP/Alb ratio, clinicopathological parameters, and overall survival (OS) were evaluated. ⋯ At last, we evaluated the prognostic value of the CRP/Alb ratio compared with the similar inflammation-based prognostic scores GPS and mGPS using the area under the curve (AUC). Although the differences were not statistically significant, the AUC value of the CRP/Alb ratio (continuous, categorical) was higher compared with the GPS and mGPS, except that the AUC value for the CRP/Alb ratio (categorical) at 3 years was lower than that for the GPS. The CRP/Alb ratio could take the place of the GPS and mGPS in terms of predicting prognosis in CCRCC.
