[Characteristics and Source Apportionment of Ambient Volatile Organic Compounds in Shijiazhuang High-tech Industrial Development Zone in Autumn].

Utilizing the online monitoring data of volatile organic compounds （VOCs） and ozone （O） in the Shijiazhuang high-tech industrial development zone during October 2020, the pollution characteristics of VOCs were analyzed. Subsequently, ·OH estimation, secondary organic aerosol formation potential （SOAP）, and ozone formation potential （OFP） were applied to assess the chemical reactivity of VOCs. Additionally, the source apportionment was identified using the positive matrix factorization （PMF） model.

[Clinical Efficiency and Safety of the First-line CHOP Regimen Containing PLD Applied to Treat Aged Patients with Advanced DLBCL].

Objective: To explore the clinical efficiency and safety of CHOP regimen containing pegylated liposomal doxorubicin (PLD) for the aged patients with advanced diffuse large B-cell lymphoma (DLBCL).

Methods: Fifty aged patients with advanced DLBCL treated in our hospital from February 2010 to February 2014 were selected and divided into two groups. Out of 50 cases, 25 cases received standard CHOP regimen (sCHOP group), other 25 cases received CHOP regimen containing PLD at dose of 30 mg/m2 (PLD+CHOP).

Dispersion of ventricular mRNA of RyR2 and SERCA2 associated with arrhythmogenesis in rats.

Aim: To investigate the effect of CPU86017 on the changes of mRNA abundance of different calcium handling system in infarcted heart.

Methods: Rats were subjected to left coronary ligation to induce myocardial infarction (MI). The treatment with either propranolol (Pro) 5 mg/kg ip or CPU86017 1, 2, and 4 mg/kg ip was initiated on the next day of operation and continued for 20 d.
