Objective To observe the effects of mind-regulating brain-developing acupoint magnetic therapy in patients with mild cogni-tive impairment (MCI). Methods From May to October, 2015, 60 patients with MCI were randomly divided into control group (n=30) and observation group (n=30). The control group received magnetic therapy on Yangming meridians, and the observation group received magnet-ic therapy on mind-regulating brain-developing acupoints, for two months. They were assessed with Montreal Cognitive Assessment (Mo-CA), digit-span and digit symbol of Wechsler Adult Intelligence Scale (WAIS). Results After treatment, the scores of MoCA, digit-span and digit symbol of WAIS significantly increased in the observation group (t>4.858, P<0.001), and were higher than that in the control group (t>2.188, P<0.05), however, only the scores of MoCA and digit symbol of WAIS significantly increased in the control group (t>5.527, P<0.001). The scores of visual space and execution, and delayed recall of MoCA increased in the observation group (t>2.324, P<0.05), and were higher than that in the control group (t>2.262, P<0.05) after treatment, and no significant difference was found in other domains (P>0.05). Conclusion Magnetic therapy on acupoints related with cognition could improve the cognitive function in patients with MCI.

The osmotic pressure of ammonium sulfate solutions has been measured by the well-established freezing point osmometry in dilute solutions and we recently reported air humidity osmometry in a much wider range of concentration. Air humidity osmometry cross-validated the theoretical calculations of osmotic pressure based on the Pitzer model at high concentrations by two one-sided test (TOST) of equivalence with multiple testing corrections, where no other experimental method could serve as a reference for comparison. Although more strict equivalence criteria were established between the measurements of freezing point osmometry and the calculations based on the Pitzer model at low concentration, air humidity osmometry is the only currently available osmometry applicable to high concentration, serves as an economic addition to standard osmometry.

Objective To explore the relationship of different body mass index, waist circumference and serum lipid levels with essential hypertension among residents of Ningbo. And to explore the predictive value of BMI and WC (Waist Cir-cumference) for hypertension. Methods Adopting cluster sampling, 2 303 people (1 081 cases of hypertension and 1 222 people with normal blood pressure) were collected in the four townships of Ningbo City. We conducted questionnaires, physi-cal examination and blood lipid testing for all of subjects. WC group:WC≥85 cm in male or WC≥80 cm in female is central obesity, and the others are normal. BMI groups:BMI≥24 kg/m2 is overweight, and BMI<24 kg/m2 is normal. The relationship of BMI, WC and serum lipid levels with hypertension was analyzed by multivariate unconditional logistic regression model. The predictive value of BMI and WC for hypertension was analyzed by receiver operating characteristic (ROC) curve. Results WC, BMI, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in hypertension group were higher than those in control group (P<0.01). And WC, BMI, TG, LDL-C is the impact factor for hypertension. The overweight rate and central obesity rate in hypertension group were higher than control group (P<0.01). TG and LDL-C level abnormality, overweight and central obesity were the risk factors of hypertension. As a risk factor of hypertension, over-weight with central obesity group is higher than overweight with normal waistline group, simple central obesity group and nor-mal group. In the area under the ROC curve, BMI is higher than WC in both male and female population. Conclusion WC, BMI, TG and LDL-C abnormalities were risk factors for hypertension, and BMI was a better predictive factor for hyper-tension than WC.
