Objective To study the long-term neurodevelopment in term neonates with hyperbilirubinemia and explore the predictive value of cerebrospinal fluid neuron specific enolase (CSF-NSE) on long-term neurodevelopment outcome.Methods A mental and psychomotor scale for 0-4 years old was performed to evaluate the intelligence development of 39 neonates with hyperbilirubinemia and 39 randomly selected healthy controls when they were at 3 to 24 months old. The former were tested for the level of CSF-NSE in jaundice climax.Results There was significant difference between 2 groups in total development quotient (DQ) tested at 3 month and 24 month old (P=0, 0.047). It was shown that the DQ scores for fine activity and social behavior were significantly lower in the study group than those in the control group (Pa=0). Furthermore, within the hyperbilirubinemia group, CSF-NSE was significantly associated with DQ of 3 month and 24 month old, while there was not association with TSB. The correlation coefficients were -0.46(P=0.04) and -0.32(P=0.047),respectively.Conclusions Hyperbilirubinemia may influence long-term neurodevelopment of term infants and CSF-NSE can predict this outcome.

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.

Objective To explore the relationship between IL-1?-511C/T and IL-1?+3953C/T site polymorphisms and the susceptibility of pediatric epilepsy.Methods Under the case-control study,IL-1?-511C/T and IL-1?+3953C/T site polymorphisms in 117 patients with pediatric epilepsy and 95 healthy individuals controls(healthy control group) were analyzed with polymerase chain reaction restriction and fragment length polymorphism(PCR-RFLP),the relationship between IL-1?-511C/T,IL-1?+3953 C/T site polymorphisms and the risk of pediatric epilepsy were analyzed.SAS 8.0 software was used to analyze the data.Results Multiple variate logistic regression analysis revealed that compared with healthy control group,there was no relationship between the IL-1?-511C/T site polymorphisms and the susceptibility of pediatric epilepsy individuals,carrying at least one +3953T variant allele(CT and TT genotypes) had a significantly increased risk for pediatric epilepsy(adjusted OR=2.46,95%CI 1.03-5.87),compared with the wild-type genotype(+3953CC).Furthermore,individuals with epilepsy or febrile seizures family history had a significantly higher risk(adjusted OR=4.12,95%CI 1.28-29.34),compared with those with both CC genotypes.Conclusions These findings support the hypothesis that IL-1?-511C/T site polymorphisms have no relationship with epilepsy,but the IL-1?+3953C/T polymorphism may contribute to the risk of developing pediatric epilepsy.

Objective To evaluate the diagnostic value of EUS in patients with chronic abdominal pain of suspected pancreatic origin.Methods The EUS findings and related clinical data of 106 patients with chronic abdominal pain of suspected pancreatic origin(excluding the patients with suspected pancreatic malignancies)from 1991 to 2004 in PUMCH were retrospectively analyzed.Results(1)The principal dis- ease interpreting the chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignan- cies)was chronic pancreatitis(CP)(57.5%),the following contributions were other pancreatic diseases (18.9%)and unknown diseases(11.3%).(2)The sensitivity and specificity of EUS for diagnosing CP was 95.1% and 64.4% respectively,the positive predictive value(PPV)and negative predictive value (NPV)was 78.4% and 90.6% respectively.(3)Abhormalities of pancreatic parenchyma structure based on EUS were the main findings(90.2%)in patients with CP and non-homogeneous echo pattern combined with hyper echoic dots or calcification was the predominant feature(52.5%).The value of isolated inhomo- geneity and focal enhanced eehogenicity for diagnosing CP were limited(P>0.05).Abnormalities of pan- ereatic ductal system were presented in 63.9% of patients with CP and dilation of pancreatic duct was the major feature(34.4%).CP with focal mass(inflammatory pseudotumor)was usually presented as hypo e- choic mass in the pancreatic head based on EUS(90%),which was similar to the EUS feature of pancreatic cancer.(4)The general accordant rate based on EUS with ERCP or BT-PABA were 77.8% and 70.4% re- spectively,and the correct rate based on combine diagnosis were 100% and 95.2%.Conclusion CP is the main source of chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignancies). EUS has good sensitivity but inadequate specificity for diagnosing CP,while ERCP may be more sensitive than EUS for detecting pancreatic ductal lesions.Pancreatic parenchymal abnormalities contribute the major EUS features of CP but the value of isolated inhomogeneity and focal enhanced echogenicity for diagnosing CP are limited.
