Objective To explore the changes of weight,body mass index(MBI),serum glucose,serum insulin in sodium valproate(VPA)-treated children with epilepsy.Methods The study was carried out in 30 epileptic children treated with VPA for 3 months.Weight,height,serum glucose and insulin levels were conducted before and after VPA treatment.Serum insulin levels were detected by radioimmunoassay.Results After 3 months' treatment,body weight [(15.68?3.82)kg vs(19.64?4.75)kg,t=3.56 P0.05].Conclusions VPA therapy can make insuline weight,BMI,serum insulin increased and may lead to insulin resistance.Insulin resistance may be one of the reasons for weight gain in VPA-treated patients.

Objective To investigate the influence of sedentary behavior on chronic diseases of different occupational groups in Jiading District. Methods We studied the sedentary time and the morbidity of chronic illnesses among different occupational groups aged between 20 and 74 in Anting town, Huating town and Huangdu town. Results The overall prevalence of hypertension (37.88%) was greater than that of diabetes (8.64%), and the prevalence of both chronic diseases in men was greater than that in women.There was a difference in prevalence between the two types of chronic diseases in different occupational groups.The length of time the subjects sat or leaned on each day was consistent with the occupational distribution of the two chronic diseases. Conclusion The prevalence of chronic diseases among different occupational groups may be related to sedentary behavior.CDC and community should promote education and encourage sports among these occupations.

OBJECTIVETo investigate the feasibility of dynamic magnetic resonance diffusion tensor imaging (DTI) in rabbit models with implanted VX2 hepatic tumor grafts.

METHODSMRI and DTI images were obtained from 16 rabbit models with implanted VX2 hepatic tumor grafts (14, 18, 22, and 26 days after tumor implantation, respectively) and 4 normal rabbits. The average diffusion coefficient (ADC) and exponential ADC (eADC) were estimated and compared against pathological findings.

RESULTSThe ADC values increased after tumor implantation but then decreased in the rabbit models, whereas eADC exhibited a pattern of reverse changes. These changes significantly differed from those in the control group. Coagulation necrosis and fibrous hyperplasia showed obvious increase as found by pathological examination.

CONCLUSIONDynamic MR DTI quantitative analysis of rabbit models of implanted VX2 hepatic tumor can partially describe the growth behaviors of implanted liver cancer.

With the development of treatment, the survival rate of premature infants has significantly increased, especially extremely premature infants and very low birth weight infants. This has led to an increase in incidence of bronchopulmonary dysplasia (BPD) year by year. BPD has been one of the most common respiratory system diseases in premature infants, especially the small premature infants. Arrested alveolar development is an important cause of BPD. Therefore, the mechanism of arrested alveolar development and the intervention measures for promoting alveolar development are the focuses of research on BPD. Selecting the appropriate animal model of BPD is the key to obtaining meaningful results in the basic research on BPD. Based on above, several common methods for establishing an animal model of BPD and the corresponding changes in pathophysiology are summarized and evaluated in order to provide a reference for selecting the appropriate animal model in studies on the pathogenesis, pathophysiology, and prevention and control strategies of BPD.

This paper reported a case of congenital hyperinsulinism and reviewed the relevant literatures regarding to the etiology, pathogenesis, clinical and pathological features, diagnosis and treatment of this disorder. The baby (male), with gestational age of 36 weeks and birth weight 4,200 g, was delivered by caesarean section. It presented with hypoglycemia immediately after birth (0.8 mmol/L). Through the course of the disease, the baby's blood sugar manifested with 1.2-2.8 mmol/L although glucocorticoid was administered. 10% glucose solutions were intravenously infused at a speed of 10-17 mg/(kg x min) for this patient to retain a stable blood sugar level. The plasma insulin level was 24.13 U/L and blood sugar level was 1.5 mmol/L on day 30 of his life. The ratio of plasma insulin (U/L) and plasma glucose (mg/dL) was 0.89. These results suggest an inappropriate insulin secretion resulting in persistent hypoglycemia in this baby and so it was definitely diagnosed with congenital hyperinsulinism.
