Sperm Parameters, ASAs and Apoptosis After Processing by the Double Tube and Swim up Methods.

The aim of this study was to improve the quality of semen samples by using a novel double-tube (DT) method. The DT method was developed to select sperm and compared with traditional swim-up (SU) technique for 31 semen samples. Sperm DNA integrity were tested with TUNEL and SCSA.

Effect of scrotal heating on sperm quality, seminal biochemical substances, and reproductive hormones in human fertile men.

At present, male contraceptive methods are only vasectomy and condoms, so it is necessary to research on male contraceptive techniques. The aim of this study is to observe the effects of scrotal heating (SH) on semen parameters, seminal l-carnitine (LC), epidermal growth factor (EGF), macrophage migration inhibitory factor (MIF), reproductive hormones and sperm chromosome numbers of adult healthy men, and to provide the experimental data for male contraception. The scrotums of 30 healthy male volunteers were exposed to the condition of 40 to 43°C SH belt warming 40 minutes each day for successive 2 days per week.

[Older age is not related to hemorrhagic transformation and favorable outcomes in patients with wake-up ischemic stroke undergoing intravenous thrombolytic therapy].

Objective: To investigate factors related to hemorrhagic transformation and favorable outcomes in wake-up ischemic stroke (WUIS) patients undergoing intravenous thrombolytic therapy.

Methods: Clinical data of 600 patients undergoing multimodal image-guided intravenous recombinant tissue plasminogen activator (rt-PA) therapy in Department of Neurology, the Second Affiliated Hospital, Zhejiang University School of Medicine center from May 2009 to May 2015 were retrospectively analyzed. Among 600 patients, 68 were diagnosed as WUIS including 17 cases aged 80 or older.

Octarepeat peptides of prion are essential for multidrug resistance in gastric cancer cells.

Objective: In previous studies cellular prion protein (PrPc) is confirmed to be involved in multidrug resistance (MDR) of gastric cancer. Although octarepeat peptides are important functional domains of PrPc and are closely related to the transport of Cu2+/Zn2+ and antioxidative function, the significance in MDR remains unknown. We aimed to investigate the role of octarepeat peptides in gastric cancer MDR.

[Study on the present status of the areas with high iodine concentration in drinking water and edible salt at household levels in Ohio of Yellow River].

Objective: To understand the present condition of iodine excess areas and edible salt at household levels in Ohio of Yellow River,which will provide the evidence to control it.

Methods: A cross section in one time was adopted for the epidemiological survey based on the east, west, south, north and central in all of townships from 8 counties. 2 samples of drinking water from each village were tested their water iodine content as well as the data regarding to their recourses and the depth of wells.
