Objective To study the combined effect of extremely low frequency electromagnetic fields ( ELF-EMF ) exposure (50 Hz and 3 mT) and high temperature exposure on hsp22 and hsp26 expression in Drosophila melanogaster. Methods Under the conditions of 50 Hz and 3 mT ELF-EMF,the male and female D.melanogaster was separately exposed for 2 h at 25℃, 27.5℃, 30℃, 32.5℃,and 35℃, respectively.The death rate, exercise capacity and the hsp22 and hsp26 expression levels of D.melanogaster were detected after exposure;or at 25℃and 35℃at 2 h, 4 h, 8 h, and 24 h, respectively.The hsp22 and hsp26 expression levels of D.melanogaster were tested after exposure .Results After exposure for 2 h at 25℃, 27.5℃, 30℃, 32.5℃, and 35℃, temperature had a significant effect (P<0.01) on the death rate, exercise capacity and the hsp22 and hsp26 expression levels of D.melanogaster, but ELF-EMF had no significant effect (P>0.05).After exposure for 2 h at 25℃, 27.5℃, 30℃, 32.5℃, and 35℃, the hsp22 and hsp26 expression levels of D.melanogaster were significantly impacted(P<0.01) by gender, temperature, ELF-EMF and exposure time, and tem-perature was the most important factor .Gender, temperature, ELF-EMF and exposure time had some interaction with the results.Conclusion ELF-EMF can influence the expression levels of hsp22 and hsp26.ELF-EMF exposure contributes to heat tolerance in D.melanogaster through accelerated expression of hsp22 and hsp26.

Objective To evaluate the nutrition status of the elderly patients with type 2 diabetes. Methods The nutrition status of 100 elderly patients〔male 52, female 48, aged 60-83 yrs, with average of (69.2?0.7)yrs〕 with type 2 diabetes was investigated by analyzing nutrient content in daily diet, body measurement and laboratory examinations. Results Compared with the ideal body weight, total calorie intake was suitable for the elderly patients〔male: (1592?216) kCal, female: (1320?172) kCal〕, fat intake 〔male:(67?12) g, female:(65?13)g〕 was higher than the standard for diabetics(P

Objective To analyze the CT contrast enhanced features of the extra-organic primary tumors in pelvis and to evaluate anatomic bases of these imaging characteristics.Methods CT findings in 14 patients with pathologically proved extra-organic primary tumors in pelvis were reviewed retrospectively for tumor size,density,margins,contrast enhanced characteristics,location and relationship of the lesions with surrounding organs and tissues.Results There were benign tumors (n=3) and malignant tumors(n=11) in this study.There were 6 lesions in peritoneal cavity and 6 in retroperitoneal space of pelvis respectively,and two other masses were in both peritoneal cavity and retroperitoneal space of pelvis.CT scan revealed that there were 6 solid masses and 8 cystic-solid masses.The enhanced characteristics of lesions were homogeneous and heterogeneous in 3 and 11 patients respectively.The fatty space surrounding the lesion was invasive in 7 cases and all of them were malignant tumor.The fatty space surrounding lesion was clear in other 7 cases including 3 benign tumors and 4 malignant tumors.CT revealed calcification in 4 lesions including benign teratoma (n=2) , malignant teratoma (n=1), and carcinoid (n=1).Conclusion In the diagnosis of extra-organic primary tumors in pelvis,CT enhancement scan can reveal the anatomic location and relationships of the lesions with surrounding organs and tissues and can differentiate benign and malignant tumor to some degree.

Background & Objective: Sleep quality in neuromyelitis optica spectrum disorders (NMOSD) were investigated in two recent studies. However, factors affecting sleep quality have not been studied in NMOSD. This study aimed to investigate the prevalence of sleep disorders in Chinese outpatient clinics with NMOSD and its clinical correlates. Methods: We administered Chinese validated self-questionnaires on HRQOL (MSQOL-54), sleep (PSQI), pain (SF-MPQ-2), anxiety (HARS) and depression (HDRS) to 42 patients followed up in our outpatient department. We assessed the relationships between sleep quality with pain, anxiety, depression, gender, age, disability, disease duration, NMO-antibody status and explored the determinants of poor sleep quality. Results: Sixty four percent of NMOSD patients were poor sleepers. Significant correlations were found between duration, disability, pain, anxiety, depression and sleep quality. Disability, depression and the domain of affective descriptors of pain were the three main predictors of poor sleep in NMOSD. Conclusion: This study reveals that poor sleep in NMOSD is common and it decreases physical function of quality of life. It is worthwhile considering exploring adjuvant strategies aimed at controlling pain associated affect, and treatment of depression may help to improve sleep quality in NMOSD.

Objective:To analyze influencing factors for sarcopenia in people of advanced age, in order to provide insight and evidence for the prevention and treatment of sarcopenia in people belonging to this age group.Methods:Data from 167 people of advanced age seeking care at our department from December 2014 to July 2017 were retrospectively analyzed.According to the diagnostic criteria for sarcopenia of the Asian Working Group for Sarcopenia, subjects were divided into the sarcopenia group( n=46, 27.5%)and the non-sarcopenia group( n=121). Differences in body composition, energy intake, quantities and proportions of three major nutrients were analyzed between males and females.Related influencing factors for sarcopenia were analyzed by using multiple linear regression. Results:Compared with the non-sarcopenia group, the sarcopenia group had lower body mass index, waist-hip ratio, fat mass, total energy intake and protein( P<0.05)but higher age and fat intake( P<0.05). Values for grip strength, muscle mass, index of skeletal muscle, adjusted muscle mass by body mass index, total energy intake, carbohydrates, fat and protein were lower and the percentage of body fat was higher in females than in males( P<0.05). Multiple Logistic regression analysis showed that insufficient intake of protein( β=-0.290, OR=0.748, 95% CI: 0.569-0.984, P<0.05), reduction of body fat mass( β=-2.673, OR=0.069, 95% CI: 0.010-0.488, P<0.05)and excessive visceral fat accumulation( β=0.739, OR=2.094, 95% CI: 1.219-3.597, P<0.01)were correlated with sarcopenia in people of advanced age. Conclusions:The occurrence of sarcopenia is higher in people of advanced age and is related to insufficient intake of protein, reduction of body fat mass and excessive visceral fat accumulation.Individualized nutrition evaluation and support should be carried out as early as possible for people in this age group.

Objective:To investigate the muscular quality and its related influencing factors in elderly with sarcopenic obesity.Methods:The internalized 696 elderly subjects meeting inclusion and exclusion criteria were divided into four groups including the sarcopenic obesity(n=55), sarcopenia(n=8), simple obesity(n=481)and normal control(n=152)groups.The intergroup difference was retrospectively analyzed in the parameters of body composition, dietary intake of total energy and three major nutrients and their proportions.Multiple linear regression analysis was used to analyze the influencing factors related to the occurrence of sarcopenic obesity in the elderly.Results:The sarcopenic obesity group versus normal control group showed a higher level or value in age, body mass index, waist-hip ratio, fat mass, percentage of body fat, visceral fat area, fasting blood glucose, estimated glomerular filtration rate( P<0.01 or 0.05), and showed a lower level or value in grip strength, skeletal muscle, skeletal muscle index, muscle quality(grip strength/limb skeletal muscle), intake of energy, carbohydrate, fat and protein, body weight-adjusted intake of energy and protein, as well as ideal body weight-adjusted intake of energy and protein( P<0.01). The detection rate of sarcopenic obesity was 7.90%(n=55), including 7.60% in males(n=48)and 11.48% in females(n=7 cases). The detection rate of sarcopenic obesity was increased along with increasing age with 0.07%(2/287)in 60-69 years old group, 4.94%(12/243)in 70-79 years old group, and 24.70%(41/166)in ≥80 years old group( χ2=87.76, P<0.01). Taking the median point of grip strength/limb skeletal muscle volume as the cutoff point, the decrease rate of muscle quality was 12.36%(86/696)in total elderly subjects, 2.63%(4/152)in the control group, 11.64%(86/635)in the obesity group, 37.5%(3/8)in the sarcopenia group and 41.82%(23/55)in the sarcopenic obesity group, with an increasing trend of the decrease of muscle quality, which had significant differences( χ2=62.25, P<0.01). Multiple logistic regression analysis showed that aging, excessive visceral fat area, insufficient protein intake and decreased basal metabolism were the independent risk factors for sarcopenic obesity in elderly people( P<0.01 or P<0.05). Conclusions:The incidence of decrease of muscle quality is higher in the elderly with sarcopenic obesity than other elderly groups.Sarcopenic obesity is correlated with aging, insufficient intake of protein, decreased basal metabolism and excessive visceral fat accumulation.Individual evaluation and support is necessary in elderly people with sarcopenic obesity.

Objective To investigate the reproductive endocrine status of women with epilepsy at childbearing age and to systematically analyze the clinical features of reproductive endocrine disorders,especially polycystic ovarian syndrome (PCOS),to facilitate early detection and timely intervention.Methods In this study,scoring of anthropometry and physical signs,menstrul assessment,examination of sex hormone and pelvic ultrasound in women with epilepsy at childbearing age were performed,and the data such as overweight,central obesity,oligo/amenorrhea,luteinizing hormone (LH)/follicule-stimulating hormone (FSH),hyperandrogenism and polycystic ovary (PCO) were collected. The characteristics of their reproductive endocrine hormone disorders were analyzed statistically. Results The age of these patients was (22. 5 ± 7.0 ) years,and women younger than 30 years old and at their peak fertility accounted for 84. 89%. The prevalence rate of PCOS in women with epilepsy at childbearing age (12. 75% ) was significantly higher than that of ordinary women at childbearing age (7.2%) in China.Highly specific indicators for PCOS were hyperandrogenism (100%),LH/FSH ＞ 2 (93%) and oligo/amenorrhea (90%),whilst the highly sensitive indicators for PCOS were PCO (92%), oligo/amenorrhea (85%) and hyperandrogenism (54%). This study revealed statistically significant difference in LH,LH/FSH and testosterone (T) between PCOS group (LH: (10.24 ± 6.92) IU/L; LH/FSH;(2.20 ± 1.16);T: ( 1.07 ± 0. 35) ng/ml) and non-PCOS group ( LH: (4. 16 ± 2.62 ) IU/L; LH/FSH:( 0. 87 ± 0. 56 );T: (0. 46 ±0. 25) ng/ml,t = -3. 899,-4. 240 and -4. 918 respectively,all P ＜0. 01 ). Conclusions Hormone indices are objective indicators for the diagnosis of PCOS. In clinical practice,attention should be paid to height,weight,abodominal circumference,menstrul history and ultrasound examination of the ovary in women with epilepsy.When reproductive endocrine hormone disorders are suspected from clinical features,the sex hormones (T,LH,and FSH ) should be checked to allow timely detection and early interventions.
