Novel ratio-expressions of genes enables estimation of wound age in contused skeletal muscle.

Given that combination with multiple biomarkers may well raise the predictive value of wound age, it appears critically essential to identify new features under the limited cost. For this purpose, the present study explored whether the gene expression ratios provide unique time information as an additional indicator for wound age estimation not requiring the detection of new biomarkers and allowing full use of the available data. The expression levels of four wound-healing genes (Arid5a, Ier3, Stom, and Lcp1) were detected by real-time polymerase chain reaction, and a total of six expression ratios were calculated among these four genes.

Derivation and elimination of uremic toxins from kidney-gut axis.

Uremic toxins are chemicals, organic or inorganic, that accumulate in the body fluids of individuals with acute or chronic kidney disease and impaired renal function. More than 130 uremic solutions are included in the most comprehensive reviews to date by the European Uremic Toxins Work Group, and novel investigations are ongoing to increase this number. Although approaches to remove uremic toxins have emerged, recalcitrant toxins that injure the human body remain a difficult problem.

Exploring postmortem succession of rat intestinal microbiome for PMI based on machine learning algorithms and potential use for humans.

The microbial communities may undergo a meaningful successional change during the progress of decay and decomposition that could aid in determining the post-mortem interval (PMI). However, there are still challenges to applying microbiome-based evidence in law enforcement practice. In this study, we attempted to investigate the principles governing microbial community succession during decomposition of rat and human corpse, and explore their potential use for PMI of human cadavers.

Postmortem Interval Estimation Using Protein Chip Technology Combined with Multivariate Analysis Methods.

Objectives: To estimate postmortem interval (PMI) by analyzing the protein changes in skeletal muscle tissues with the protein chip technology combined with multivariate analysis methods.

Methods: Rats were sacrificed for cervical dislocation and placed at 16 ℃. Water-soluble proteins in skeletal muscles were extracted at 10 time points (0 d, 1 d, 2 d, 3 d, 4 d, 5 d, 6 d, 7 d, 8 d and 9 d) after death.

Effect of Iron-Erythrocyte Metabolism-Related Indexes on Posttraumatic Growth in Patients on Maintenance Hemodialysis (MHD).

Purpose: To investigate the effect of iron-erythrocyte metabolism-related indexes on posttraumatic growth in MHD patients and their caregivers.

Patients And Methods: A total of 170 pairs of MHD patients and their caregivers in Shanghai Changhai Hospital were enrolled in this research, which used sociodemographic characteristics, the Posttraumatic Growth Inventory (PTGI), the Perceived Social Support Scale (PSSS), and the Medical Coping Modes Questionnaire (MCMQ). The test data of 141 patients were retrieved from the hospital database.

[Analysis of correlation between breast cancer molecular subtypes and prognosis of patients receiving breast-conserving therapy].

Objective: To evaluate the effects of molecular subtypes on the prognosis of breast cancer patients after BCT (breast-conserving therapy).

Methods: From January 1999 to December 2007, a total of 699 female patients on BCT were analyzed retrospectively. They were grouped according to the results of immunohistochemistry, they were grouped as Luminal A (ER+/PR+/HER2-, Ki-67 < 14%), Luminal B (ER+/PR+/HER2 ± , Ki-67 > 14%), HER2 (ER-/PR-/HER2+) and triple negative breast cancer (TNBC) (ER-/PR-/HER2-).
