Objective To study the etiologies of long duration fever in neonates and to provide clinical evidence for early diagnosis and intervention. Methods From January 1st, 2004 to December 31st, 2013, data from neonates admitted to the Department of Neonatology, Childrenˊ s Hospital of Chongqing Medical University were retrospectively analyzed. Results Among 238 neonates with long duration fever, 165 cases were male and 73 female. Pneumonia(n = 196), skin / mucosa infection (n =67), sepsis (n = 46), meningitis/ encephalitis (n = 25) and neonatal necrotizing enterocolitis (n = 24) were the most common etiologies. Diabetes insipidus was the only noninfectious cause of fever in this study. The incidence of high fever in cases diagnosed with meningitis/ encephalitis, sepsis, diabetes insipidus, immunodeficiency or urinary tract infection were significantly higher than other causes (P <0. 05) . Continuous fever or other special fever types were more common in cases diagnosed with pneumonia ( χ2 = 4. 581, P = 0. 032 ) . Incidences of sepsis, infectious diarrhea or meningitis/encephalitis in late neonates were significantly higher than early neonates ( P < 0. 05 ) . Conclusions Long duration fever in neonates is most likely caused by infectious diseases and diabetes insipidus is the only noninfectious cause of neonatal fever in our study.

The authors describe the methods of processing and preservation of human amniotic membrane, and the histological study and clinical application experiences as well.

Objective To investigate the energy intakes and energy consumption in continuous ambulatory peritoneal dialysis (CAPD) patients,and to identify the possible influence factors for overweight and obesity of CAPD patients.Methods A total of 115 CAPD patients were enrolled from May to December 2011 in Peking University Third Hospital.Based on body mass index (BMI),they were divided into normal group (18.5 kg/m2 ≤ BMI < 24 kg/m2,n =61) and obese group (BMI ≥ 24 kg/m2,n =54).Three-day dietary intakes including dietary energy,protein,fat,and carbohydrates intakes were collected.Glucose absorption from dialysate was measured.Three-day activities were recorded for the calculation of resting energy expenditure (REE) and total energy expenditure (TEE).Body composition of the patients was analyzed.Results There were no significant differences in age,height,dietary energy intake,protein intake,carbohydrate intakes,lean tissue mass,and hydration status between the two groups.Glucose absorption from dialysate and dietary fat intake were significantly higher in the obese group than in the normal group [(1 920.5 ± 506.3) kJ/d vs.(1 673.6 ±535.6) kJ/d,x2 =2.536,P=0.013; (62.5 ±19.8) g/dvs.(53.1 ±18.7) g/d,x2=2.575,P =0.011].Although REE was higher in the obese group as compared with the normal group [(5 066.8 ±1 029.3) kJ/d vs.(4 556.4 ± 799.1) kJ/d,x2 =2.979,P =0.004],there was no significant difference in TEE between the two groups [(7 819.9 ±728.0) kJ/d vs.(7 803.2 ± 1 092.0) kJ/d,x2 =0.770,P =0.939].Logistic regression showed that glucose absorption from dialysate and dietary fat intakes were risk factors for obesity in the study population (OR =1.003,95％ CI =1.000-1.007,P =0.029 ; OR =1.024,95％ CI =1.003-1.046,P =0.027).Conclusions Obese CAPD patients may absorb more glucose from peritoneal dialysate and consume more fat than non-obese CAPD patients,but TEE is not significantly different.It indicates that obese CAPD patients are at positive energy balance.Less use of high glucose dialysate and more physical exercises are recommended for these patients.

Objective To investigate the CT manifestations in mesenteric injury.Methods CT imaging data were analyzed retrospectively in 28 patients with mesenteric injury caused by abdominal trauma,of which 26 patients were confirmed by surgery and 2 patients received conservative treatment.Results CT showed simple mesenteric injury in 5 cases,and multiple organ injury in other 23 cases.Only 18 cases were dignosed by preoperative abdominal CT,and the rate of missed diagnosis was 36%.Conclusion Multi-slice CT is an important evaluation method for the detection of acute mesenteric injury.

OBJECTIVE:To prepare Venlafaxine hydrochloride sustained-release tablets,and to investigate the characteristics of drug release. METHODS:Using glyceryl behenate as lipidic matrix material and HPMC as hydrophilic matrix material,the kind and dosage of excipients were screened by single factor experiment. Using 4,8,24 h accumulative release rate and the deviation summation of ideal values as index,the viscosity of HPMC,the amounts of HPMC K15M and glyceryl behenate were optimized by orthogonal test. The dissolution curves were fitted by different equations. RESULTS:The optimal formulation was as follows as venlafaxine hydrochloride 8.5 kg,HPMC K15M 15 kg,glyceryl behenate 26 kg,magnesium stearate 0.5 kg. 4,8,24 h accumula-tive release rates of prepared matrix sustained-release tablets were 34.3%,63.9% and 99.2%,respectively. The releases profiles of hydrophilic and lipidic matrix sustained release tablets followed first-order equation in vitro mainly through matrix erosion. CON-CLUSIONS:Venlafaxine hydrochloride hydrophilic and lipidic matrix sustained-release tablets with good sustained-release effect have been prepared successfully.
