Neonatal jaundice or hyperbilirubinemia is a common occurrence in newborns.Most cases of neonatal jaundice have a benign course.Hyperbilirubinemia can be best understood as a balance between the production and elimination of bilirubin,with a multitude of factors and conditions affecting each of these processes.When an imbalance results because of an increase in circulating bilirubin ( or the bilirubin load)to significantly high levels( severe hyperbilirubinemia),it may cause permanent neurologic sequelae( kernicterus),which is preventable if the hyperbilirubinemia is identified early and treated appropriately.Phototherapy for jaundice is a common treatment in neonatal medicine and is used to prevent the neurotoxic effects of bilirubin.Phototherapy for hyperbilirubinemia should be based primarily on total serum bilirubin levels of the infant's age in hours and other factors that affect the risk of bilirubin encephalopathy.

Objective To investigate MSCT findings of cystic masses of the neck.Methods The clinical and CT imaging data of 36 cases with cystic neck lesions including 1ymphsdenopathy 9 cases,abscesses 3 cases,salivary lesions 2 cases,thyroid lesions 2 cases,thyroglossal duet cysts 9 cases,branchial cleft cysts 5 cases,cystic hygromas 3 cases,deimoidcyst 1 case laryngeal mucocele 1 case and nerve sheath tumors 1 case comfired by operation-pathology were analyzed.Results The cystic features of lesions could be showed on contrast-enhaced CT,cystic alteration in lymphadenopathy were due to necrosis and presented as the cystic wall enhanced and thickened salivary cystic lesions were variable congenital cystic masses usually appeared as a smooth,well-circum scribed mass,the cystis wall Was thin and nonenhanced unless inflammation was present and most of them localized at the specific anatommic compartments thyroglossal duct cysts were mainly in the anterior midline portion of the neck at the level of the hyoid bone.Second branchial cleft was commonly in the posteriormargin of the subm and ibular gland and lateral to the carotid space.Dermoid cyst presented in the floor of the mouth.Conclusion CT can provide essential infonnatiom in evaluating the nature and location of the cystic mass of neck.which is of significance for diagnosis and preoperative planning.

Adherence to public welfare and mobilizing incentives are key to promoting the health reform,and making it a success as well.It is imperative to comprehensively and correctly comprehend the importance of mobilizing medical workers in ensuring the reform a success,based on the present practice of the health reform and by views of philosophy,economics,and management.These principles should be followed in the design and perfection of the reform mechanism.

Gangliosides are sialic acid-containing glycosphingolipids and abundant in the brain. Some studies showed that glycosphingolipids not only could improve the differentiation of neurons, neurite outgrowth and synaptogenesis, but also could modulate neuronal plasticity and improve neurological function after cerebral damage. GM1 was so far most widely studied glycosphingolipids. It is believed that the regulatory functions for calcium homeostasis and the interaction between GM1 and neurotrophins are essential in the mechanisms underlying its neuroprotection. In addition, GM1 has also anti-excitotoxicity, anti-oxidation and vasodilation properties. Various forms of chronic neurodegenerative diseases and hypoxia/ischemic encepha-lopathy are characterized by progressive loss and apoptosis of neurons, the neuroprotective and neruotrophic effects of GM1 could play pivotal role in the treatment of these diseases. Nowadays, GM1 was widely used for the treatment of Parkinson's disease, stroke, hypoxia-ischemic encephalopathy, craniocerebral trauma, spinal cord injury and peripheral neuropathy. Further researches for the mechanisms of GM1 will provide new strategies for the treatment of central nervous system diseases.

Objective To investigate the influence of patients suffered from acute lower wall cardiac infarct appeared Ⅲ atrio-ventricular block tneatment with thrombolytic recanalization for the early recovery of sinus rhythm.Methods From October 01 till October 06, a total of 25 hospitalized patients in our hospital with acute lower cardiac infarct, chest pain persist over thirty minutes, but less than one hour, immediately treatment with urokinase thrombolytic therapy after hospitalization, among them 17 cases reinfusion therapy success ful and 8 cases failed. Divided into reinfusion therapy success group and failed group, observate thromholytic therapy 6 hours recanalization success and fail group the situation of sinus rhythm recovore. Results Among 17 cases recanalization success patients and 14 cases recover sinus rhythm within 6 hours ,and 8 case fail in recanalization 2 cases recover sinus rhythm in 6 hours(25%)compared these two groups statistical are meaningful ( P＜0. 01 ). Conclusion Acute lower cardiac infarct patients with Ⅲ atrio-ventricular block must use thrombolytic therapy as soon as possible in order to let oclusive coronary artery recanalize, help to recover sinus rhythm as soon as possible and decrease mortality rate.

Calcium metabolism and the transepithelial Ca2+ active transport play important roles in many basic physiological processes,such as neurotransmission,excitation-contraction coupling, vesicular secretion. Placenta is a link between maternal and fetal,transiting all the nutritions from maternal to the fetus.The syncytionbophoblast express many sorts of calcium channels/transporters and exchangers, such as voltage-dependant Ca2+ channels, transient receptor potential channels, store-operated Ca2+ channels, calcium-binding proteins, plasma membrane Ca2+ -ATPases, Na + / Ca2+ exchanger, which exhibit specific distribution and physiological properties. Therefore, this review focuses on the tissue expression and functional properties of channels, transporters,and exchangers in syncytionboph-oblasts.
