Prevalence and Associated Factors of Tooth Wear in Shanghai.

Objective: To estimate the prevalence and distribution of tooth wear among groups of adolescents and adults in Shanghai, China through an epidemiological survey, and explore the associated factors.

Methods: Multistage, stratified, constant volume and cluster sampling methods were used in an epidemiological survey conducted in Shanghai in 2014. The basic erosive wear examination (BEWE) index was used to screen for tooth wear in different age groups: 12 years, 15 years, 18 to 35 years, 36 to 49 years and 50 to 74 years.

Relationship between periodontal disease and male infertility: A case-control study.

Objectives: To compare the prevalence of chronic periodontitis between men who had semen abnormalities and those who had normozoospermia through a case-control study.

Materials And Methods: Male patients who visited the assisted reproduction clinic of a large general hospital and were diagnosed with semen abnormalities were included in the case group. The control group was composed of patients of the same clinic with normozoospermia.

BAG-1L Protects SH-SY5Y Neuroblastoma Cells Against Hypoxia/Re-oxygenation Through Up-Regulating HSP70 and Activating PI3K/AKT Signaling Pathway.

BCL-2-associated athanogene-1(BAG-1) is a multifunctional and anti-apoptotic protein that was first identified as a binding partner of BCL-2. But the effects and mechanisms for BAG-1 against hypoxic damage is unclear up to now. Whether BAG-1 could protect the human brain against hypoxic damage through up-regulating 70 kDa heat shock proteins (HSP70) and PI3K/AKT pathway activation? In present study, we examined the changes of HSP70 and AKT and p-AKT protein level in SH-SY5Y cells with BAG-1L gene over-expression subjected to hypoxia/re-oxygenation injury.

[Investigation of sexual function in 623 patients with chronic prostatitis].

Objective: To investigate the influence of chronic prostatitis on premature ejaculation (PE) and erectile dysfunction (ED) and the correlation of chronic prostatitis with PE and ED.

Methods: We adopted NIH-CPSI, CISFPE and IIEF-5, interviewed 623 patients with chronic prostatitis, and recorded their scores on the above systems.

Results: The incidence of PE was 39.
