Spa therapy (balneotherapy) relieves mental stress, sleep disorder, and general health problems in sub-healthy people.

To investigate the relieving effects of hot spring balneotherapy on mental stress, sleep disorder, general health problems, and women's health problems in sub-healthy people, we recruited 500 volunteers in sub-health in Chongqing, and 362 volunteers completed the project, including 223 in the intervention group and 139 in the control group. The intervention group underwent hot spring balneotherapy for 5 months, while the control group did not. The two groups took questionnaire investigation (general data, mental stress, emotional status, sleep quality, general health problems, as well as some women's health problems) and physical examination (height, weight, waist circumference, blood pressure, blood lipid, blood sugar) 5 months before and after the intervention, respectively.

[Health Qigong Wuqinxi improves hydrogen proton magnetic resonance spectra in prefrontal cortex and hippocampus in college students with mild depression].

Objective: To investigate the effects of health Qigong Wuqinxi exercise on mild depression in college students and analyze the changes in hydrogen proton magnetic resonance spectra (H-MRS) in the prefrontal cortex and hippocampus after the exercise.

Methods: Fifty-eight volunteer college students, including 30 with mild depression and 28 healthy students, were randomized into the intervention group and non-intervention group. The students in the intervention group were asked to practice health Qigong Wuqinxi training for 12 weeks and those in the non-intervention group did not engage in such training.

[Effect of Benzo [α]pryene and Butylated Hydroxylanisole on Learning and Memory in Rats].

Objective: To investigate the neurotoxic effect of benzo[α]pryene (B[α]P) and protective effect of butylated hydroxyl anisole (BHA) on learning and memory in hippocampus of rats.

Methods: Ninety male, SD rats were randomly divided into blank control group, solvent control group, B[α]P exposed group [(2 mg/(kg x d)], BRA group [50 mg/(kg x d)] and B[α]P + BHA combined group. Rats were given the appropriate dose oral treatment according to body mass and group (the same volume of saline and peanut oil were given to blank and solvent control group, respectively) for 90 d.

[Rutin protects against trimethyltin-induced learning and memory impairment in BALB/c mice by antagonizing down-regulated synaptophysin expression].

Objective: To explore the protective effects of rutin against learning and memory impairment induced by trimethyltin (TMT) and investigate the possible mechanism.

Methods: Forty 6- to 9-week-old male BALB/c mice were randomized equally into saline group (control), TMT group, TMT+rutin group, and rutin group. Mouse models of learning and memory impairment were establish by acute TMT (2.

Synaptophysin and the dopaminergic system in hippocampus are involved in the protective effect of rutin against trimethyltin-induced learning and memory impairment.

Objectives: This study aimed to investigate the protective effect of rutin against trimethyltin-induced spatial learning and memory impairment in mice. This study focused on the role of synaptophysin, growth-associated protein 43 and the action of the dopaminergic system in mechanisms associated with rutin protection and trimethyltin-induced spatial learning and memory impairment.

Methods: Cognitive learning and memory was measured by Morris Water Maze.

The monitoring results of electromagnetic radiation of 110-kV high-voltage lines in one urban location in Chongqing P.R. China.

To understand electromagnetic radiation field strength and its influencing factors of certain 110-kV high-voltage lines in one urban area of Chongqing by measuring 110-kV high-voltage line's electromagnetic radiation level. According to the methodology as determined by the National Hygienic Standards, we selected certain adjacent residential buildings, high-voltage lines along a specific street and selected different distances around its vertical projection point as monitoring points. The levels of electromagnetic radiations were measured respectively.
