Objective To observe the serum adiponectin, leptin level, and adiponectin/leptin ratio (A/L ratio) in elderly male patients with normal BMI and visceral adipose deposit but without metabolic syndrome. Methods A total of 109 elderly males (≥60 years old) were enrolled whose BMI were all less than 25 kg m and without metabolic syndrome. They were divided into non visceral adipose deposit group (n = 67) and visceral adipose deposit group (n = 42 ). Serum levels of adiponectin and leptin were measured by radiological immunological assay (RIA) and the A/L ratio was calculated. Visceral adipose deposit was defined as visceral adipose area more than 100 cm2.Metabolic syndrome diagnosis was according to the definition provided by China Diabetes Society (CDS) in 2004. Results (1)The visceral adipose area [(135.56±31.72)cm2 vs. (68. 65±22.64)cm2 , P< 0. 001] and BMI [(22.94 ± 1.35 ) kg/m2 vs. ( 21.38 ± 2.55 ) kg/m2 , P < 0.001] were significantly higher in visceral adipose deposit group than in non visceral adipose deposit group. The A/L ratio was significantly lower in visceral adipose deposit group than in non visceral adipose deposit group ( 2. 17 ± 1.77 vs. 4.54 ± 7.00, P = 0. 034 ) while there was no difference in serum adiponectin or leptin level between those two groups. (2)The A/L ratio was negatively correlated with BMI (r=-0.552, P<0.001), waist circumstances (r=-0.390, P<0.001) and abdominal visceral fat area (r=-0.341, P<0. 001 ). Conclusions The A/L ratio decreases in elderly men with normal BMI and visceral adipose deposit. A/L ratio could be useful in scanning those patients with visceral adipose deposit whose BMI is normal among elderly men.

Objective:To clarify the application value of direct cortical electrical stimulation (DES) in locating vestibular functional cortices and the distribution of vestibular functional cortices.Methods:Implantation of stereo-electroencephalography (SEEG) electrodes was performed in 17 drug-resistant epilepsy patients in our hospital from January 2016 to December 2019. The clinical data of these patients were retrospectively analyzed. DES was performed on these patients and stimulation sites eliciting vestibular symptoms were selected to evaluate accurately anatomic locations of stimulation sites eliciting vestibular symptoms in standard Montreal Neurological Institute (MNI) space, and acquired accurate vestibular functional maps in groups.Results:There were 33 stimulation sites eliciting vestibular symptoms, including 9 sites (28%) located in the supramarginal gyrus, 6 sites (18%) located in the precuneus, 6 sites (18%) located in the posterior insular cortex, 1 site (3%) located in the anterior insular cortex, 4 sites (12%) located in the superior temporal gyrus, 2 sites (6%) located in the middle temporal gyrus, 4 sites (12%) located in the precentral gyrus, and 1 site located in cingulate cortex (3%). Stimulation sites eliciting vestibular symptoms induced by lowest intensity located in the insular cortex (average intensity was 2.43 mA), and the average intensity of 6 stimulation sites located in the posterior insular cortex was 2.17 mA.Conclusion:The functional cortex associated with vestibular symptoms defined by DES sites including the insular cortex, superior temporal gyrus, middle temporal gyrus, superior marginal gyrus, precuneus, precentral gyrus, and cingulate cortex.

Background: Chronic functional constipation is a common functional gastrointestinal disorder, and the effects of traditional therapeutic drugs are suboptimal. Prucalopride is a novel 5-HT
