MCU inhibition protects against intestinal ischemia‒reperfusion by inhibiting Drp1-dependent mitochondrial fission.

Intestinal ischemia‒reperfusion (IIR) injury is a common complication of surgery, but clear molecular insights and valuable therapeutic targets are lacking. Mitochondrial calcium overload is an early sign of various diseases and is considered a vital factor in ischemia‒reperfusion injury. The mitochondrial calcium uniporter (MCU), which is located on the inner mitochondrial membrane, is the primary mediator of calcium ion entry into the mitochondria.

[The correlation of synuclein-γ and matrix metalloproteinase 9 in breast cancer].

Objectives: To evaluate the expression of synuclein-γ (SNCG) and metalloproteinase 9 (MMP-9) both in the invasive ductal breast cancer samples and T47D and T47D(SNCG)- cell lines, to investigate the correlation between SNCG and MMP-9.

Methods: Totally 96 invasive ductal breast cancer samples (female, mean age of (56 ± 8) years) were collected between June 2009 and June 2012. The expressions of SNCG and MMP-9 were investigated by immunohistochemistry.

[Biofeedback therapy for fecal incontinence in patients with mid or low rectal cancer after restorative resection].

Objective: To investigate the efficacy of biofeedback therapy for fecal incontinence in patients with mid or low rectal cancer.

Methods: Twenty-four patients with mid or low rectal cancer received biofeedback treatments after restorative resection and therapeutic efficacy was evaluated using anorectal manometry and Vaizey and Wexner scoring systems. Eighteen inpatients without defecating difficulties were selected as control group.

[The effect of breast cancer specific gene 1 in the prognosis of breast cancer].

Objective: To detect breast cancer specific gene 1 (BCSG1) expression in different breast tissue, analysis its correlation with clinical parameters and evaluate the prognosis of breast cancer.

Methods: The expression of BCSG1 was detected by reverse transcription-polymerase chain reaction (RT-PCR) in surgical specimens from 84 cases of breast disease patients selected randomly at XinHua Hospital affiliated with Shanghai Second Medical University from September 1999 to December 2002. Of 84 cases, 72 case were breast cancer.
