Objective To study hemodynamics of cerebral blood flow in newborns with asphyxia.Method Bilateral cerebral electrical admittance plethysmogram(BCEAP) was used to explore characteristics of cerebral blood flow in 20 healthy newborns and 20 newborns with asphyxia respectively from first to fourth day after birth.Results Both the ratio of Hs to b-S(Hs/ b-S) and index of admittance differential loop(ADL) Ⅰ+Ⅱ decreased significantly in newborns with asphyxia compared to normal control from first to fourth day after birth(P

OBJECTIVETo evaluate the efficacy of water knife needle release combined with bone peptide injection in the management of heel pain.
METHODSThirty-five patients with unilateral heel pain were treated with water knife needle release and bone peptide injection under local anesthesia. The deep tissue with the tenderness was released in the operation, and the result was evaluated 1 week after the surgery to decide whether to conduct another surgery. No more than 3 treatment sessions were administered. The efficacy was evaluated according to nimodipine method by the principles of Chinese clinical drug guidance, and the complications of the surgery were observed.
RESULTSSix months after the surgery, 28 cases had excellent results, 3 had good outcomes, 2 showed improvement, and 2 failed to respond favorably, with a rate of good and excellent result of 94.2%. No adverse side effect was recorded in the follow up of the patients.
CONCLUSIONWater needle knife release combined with bone peptide injection can produce a good result in the treatment of heel pain.

7.Sample size requirements for association studies on gene-gene interaction in case-control study.
Chinese Journal of Epidemiology 2004;25(7):623-626
OBJECTIVESample size requirements for association studies on gene-gene interaction in case-control study.
METHODSSelecting different parameters (such as inheritance mode, susceptibility frequency, frequency of allele for disease, OR of gene main effect) and infilling them into QUANTO software based on conditional logistic regression mode.
RESULTS(1) The main parameters influencing the sample size requirements were the levels of interaction between genes and the susceptibility frequency. The numbers of sample were the same between recessive and dominant when susceptibility frequency were the same. (2) Sample size for testing of gene-gene interaction was different from that for testing of genetic effects.
CONCLUSIONIt was convenient to use the numbers of sample size from the results for gene-gene interaction in case-control study.

Objective To explore the therapeutic effect of patients with intractable by microsurgical operation.Methods All patients assisted by a 3-dimensional precise localization system of epileptic foei for epilepsy diagnosis and the epileptogenic focus and comprehensive surgical measures were taken for the treat- ment of isolated epileptic foci and their network.The outcomes of 50 patients in the following up 1~2 years were defined.A retrospective review was conducted.Results In this group,Excellent 53 cases (31.90%);good 83 cases(50.93%);moderate 10 cases(6.13%)and poor 18 cases(11.04%).The ef- fective rate was 80%.Conclusion The microsurgical management is an effective approach for treatment of refractory epilepsy.

Objective To investigate the antiproliferation and induction differentiation of human gas- tric carcinoma which human gastric lower-differentiation mucinous carcinoma MGC-803 cells transplanted in- to nude mice by using rosiglitazone(ROS),and to preliminarily explore the mechanism of differentiation. Methods The mice were randomly divided into five groups:model,ATRA,ROS 25 mg?kg~(-1),ROS 50 mg/kg, ROS 100 mg/kg.After that the volumes were measured and inhibition rates were calculated.The cell cycle was detected by FCM.The protein expression level of Mucin SAC was detected by immunohistochemistry. Results The volume of tumor decreased significantly in ROS treatment groups,the differences had statistical significance compared with model group(P0.05).The xenograft tumors of ROS groups demonstrated the characteristics of differentiation.Xenograft tumor cells were arrested in G_0/G_1 phase,and the cells in S phase decreased significantly,and up-regulated Mucin SAC gene expression.Conclusion ROS could inhibit the growth of tumor,and the effect were dose-dependent with ROS.ROS could induce the differentiation of Xenograft tumor cells of gastric cancer.Its mechanism might be related to the inhibit of transition from G_1 to S phase,degrade the activity of proliferation,regulate the expres- sion of Mucin 5AC.

Objective To investigate the influence of angelica sinenisis injection on bone marrow histology and ultrastructure in immune-induced aplastic anemia(AA) mice.Methods Female Balb/c mice were divided into normal group,model group,therapy group and contrast group.All mice were killed by cutting neck on the 12 th day, ulnas and femur were taken out. The bone marrow histology section and ultrastructure of mice ulnas were observed. The quantities of hematopoietic cells were counted. The number of femur bone marrow mononucleate cells (MNC) were measured.Results The quantities of hematopoietic cells in model group were lower than those in normal group (P
