ABSTRACT
Type 2 diabetes mellitus (T2DM) is the leading threat to human health in China, and severe cognitive impairment often occurs in most T2DM patients. Although Sagacious Confucius' Pillow Elixir is a type of classical traditional Chinese medicine for cognitive impairment in clinic, the mechanism has not yet been completely defined. In this study, an experimental model of type 2 diabetes mellitus (T2DM) was established by injecting Sprague Dawley (SD) rats with streptozocin (STZ), so as to compare the learning and memory ability, hippocampal neurons pathological changes, beta amyloid protein (A beta) content, degree of Tau protein phosphorylation, blood glucose and insulin level. The results showed that the Sagacious Confucius' Pillow Elixir could improve the learning and memory ability of STZ injected rats, reduce the level of A beta content both in hippocampus and serum, effectively reduce Tau protein phosphorylation degree, and also significantly alleviate hippocampal pathological injury, blood glucose, insulin and other basic indicators. The results showed that Sagacious Confucius' Pillow Elixir can alleviate the hippocampal pathological damage caused by STZ, and is expected to provide a theoretical basis for human T2DM patients in clinical adjuvant therapy.

This study was aimed to screen human papillomavirus (HPV) types associated with esophageal squamous cell carcinoma of Kazakh in Xinjiang using the gene chip technique and study the clinical significance of this application. The DNAs were collected from esophageal squamous cell carcinoma tissues and healthy esophageal mucosa of Kazakh adults in Xinjiang, and amplified firstly using HPV MY09/11 and then using HPV G5+/6+ to screen positive HPV specimens. These positive specimens were further detected by the gene chip technique to screen highly pathogenic HPV types. After determination with nested PCR amplification with HPV MY09/11 and G5+/6+, the infection rate of HPV was 66.67% in the esophageal squamous cell carcinoma group and 12.12% in the healthy control group. By testing the positive HPV specimens from the esophageal squamous cell carcinoma group, the infection rate of HPV16 was 97.72% and the co-infection rate of HPV16 and HPV18 was 2.27%. HPV16 infection may be involved in the development of esophageal squamous cell carcinoma in Xinjiang Hazakh adults.
