OBJECTIVE:To study the antioxidant effects of Scutellaria baicalensis(SBE)on the model mice with Alzheimer’s disease. METHODS:All mice were treated by D-gal (150 mg/kg) and NaNO2 (100 mg/kg) for 60 d to reproduce the AD model mice,ip,once a day. Totally 60 mice were randomly divided into normal control group(isovolumetric sodium chloride injection), model group (isovolumetric sodium chloride injection),estradiol (0.4 mg/kg) group,and SBE high,medium and low doses (500,250 and 125 mg/kg). The mice were intragastrically administrated while modeling except normal control group,once a day, for continuous 60 d. The superoxide dismutase(SOD),catalase(CAT)activities and malondialdehyde(MDA)content in brain tis-sue ,and glutathione peroxidase (GSH-Px) activity in serum of mice were determined. RESULTS:Compared with normal control group,the SOD,CAT activities in brain tissue,and GSH-Px activity in serum of mice in model group were decreased,MDA con-tent in brain tissue were increased,with significant difference(P<0.01 or P<0.05);compared with model group,the SOD,CAT activities in brain tissue and GSH-Px activity in serum of mice in SBE high and medium dose groups were increased,MDA content was decrease,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:SBE can enhance the antioxidant capacity in AD model mice by a mechanism that may be related to the improvement of related oxidation indicators’levels.

Objective: To assess the potential significance of proliferating cell nuclear antigen (PCNA) labelling indexes (PCNA-LI) and AgNORs number in evaluation of proliferative activity of Wilms′ tumor. Methods: A silver staining for AgNORs and an immunohistochemical method PCNA staining were performed on the biopsy specimens taken from 34 children with Wilms′ tumor. Results: No significant differences were observed between PCNA-LI and the pathological types and clinical stages, whereas fraction of S-phase and PI and the number of AgNORs were significantly higher in patients with PCNA-LI≥25% than that in patients with PCNA-LI<25%. The number of AgNORs/cell correlated well with both pathological types and clinical stages. The combination of PCNA-LI and AgNORs can accurately reflect the proliferative activity of cancer cells in Wilms′ tumor. Conclusion: The current pathological types and clinical stages may reflect the aggressive activity in Wilms′ tumor, but insufficient. The simultaneous determination of PCNA-LI and AgNORs count could be used as the essential complementarity of conventional pathological types and stages for accurate evaluation of biologic behaviour of Wilms′ tumor.

Objective To investigate the accuracy of functional magnetic resonance imaging(fMRI) and contrast-enhanced ultrasound on evaluation of the breast cancer patients after neoadjuvant chemotherapy.Methods Forty-eight patients with breast cancer who were confirmed by biopsy,undergoing 4 cycles weekly dose-concentrated programs (wPC) neoadjuvant chemotherapy,evaluated the efficacy by fMRI and contrastenhanced ultrasound.Results In pathology,complete remission was 12 cases (25.0％,12/48),non remission was 13 cases (27.1％,13/48).In contrast-enhanced ultrasound,complete remission was 20 cases (41.7％,20/48),non remission was 10 cases (20.8％,10/48).In fMRI,complete remission was 17 cases (35.4％,17/48),non remission was 11 cases (22.9％,11/48).The P values more than 0.05 showed no statistically significant among three methods,the Kappa test showed that fMRI were superior to contrastenhanced ultrasound on evaluating the efficacy of neoadjuvant chemotherapy.Conclusions fMRI and contrast-enhanced ultrasound can be used in evaluating the efficacy of neoadjuvant chemotherapy,however,the data shows fMRI is superior to contrast-enhanced ultrasound.Contrast-enhanced ultrasound must be as the supplementary method.

Objective To compare the outcomes in pregnancy between the patients with poor ovarian reservation receiving ultra-long-term down-regulation protocol and modified long-term protocol who were undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI),aiming at screening an optimal ovulation induction scheme.Methods Retrospectively analyzed the clinical data of 78 patients with poor ovarian reservation who underwent IVF or ICSI from October 2010 to July 2012.Forty-three patients received modified long-term protocol treatment (group A),with 0.375 mg long-acting triptorelin during the midluteal phase as well as superovulation start date plus alarelin (0.15 mg/d) to intramuscular injection of human chorionic gonadotropin (HCG) day.Thirty-five patients received ultra-long-term down-regulation protocol (group B).Triptorelin was injected intramuscularly in mid-luteal phase twice followed by triptorelin at a dose of 1.2-1.3 mg after 28 days of long-acting triptorehn treatment (1.5 mg).Gonadotropin was started 16 days after the second GnRHa injection.The dose of Gn,number of oocytes retrieved,number of embryos available,implantation rate,pregnancy rate,and miscarriage rate were recorded and compared between the two groups.Results There was no significant difference between the two groups in the mean age of participants,basal follicular number,FSH,the dose of Gn used,number of oocytes retrieved,number of embryos available,number of implanted embryos,Pregnancy rate(32.56％ vs.34.29％),implantation rate(18.75％ vs.20.97％) and miscarriage rate (0 vs.8.33％)(P ＞ 0.05).Conclusion No significant difference was found between the two groups in clinical pregnancy rate and abortion rate.But modified long-term protocol needs a shorter treatment period than the ultra-long-term protocol.Moreover,it reduces the risk of excessive suppression of pituitary function.Therefore,it takes advantages over the other in the clinical application.
