Objective: To select the optimum prepartion procedure for Sanhuangweixueping, Capsules. Methods: The optimum conditions were selected with the contents of active components: emodin, berberine, and baicalin as markers. Results: The optimum preparation procedure was: berberine was extracted with 95% alcohol. Rhizoma Bletillae was immersed with water, then precipitated with 70% alcohol. Radix et Rhizoma Rhei, Radix Scutellariae and Radix Glycyrrhizae were decocted, then precipitaed with 60% alcohol. Sanhuangweixueping Capsules prepared with the optimum preparation procedure possessed stronger pharmacological effect. Conclusion: The optimum prepartion procedure is reliable and the extraction ratio of active compoents is high.

Applying mitochondrial replacement technique to human assisted reproduction could benefit the fam-ilies with mitochondrial diseases and improve clinical outcomes of assisted reproduction in elderly patients. But it may also lead to a series of medical ethics issues such as the standardization and security of this technology, the conflict with the traditional ethical concepts, the determination of informed consent and confidentiality principles, the health development issues of the offspring, and commercial donation of eggs and so on. As for this, the relevant institutions should strictly control the indications when apply this technology, the government should formulate rele-vant laws and regulations. Simultaneously, it is important to strengthen supervision and management of social eth-ics, improve professional ethics of assisted reproductive personnel, and emphasize the correct guiding role of public opinion.

Objective To observe the effect of total glucosides of peony on hypergammaglobulinemia of undifferentiated connective tissue disease(UCTD). Methods Fifty patients with UCTD were randomly divided into the treat-ment group (total glucosides of peony and hydroxychloroquine and thymosin) (n=30) and the control group (hydroxychloroquine and thymosin) (n=20). The changes between the two groups on hypergammaglobulinemia after treated for 3 months were compared. Results The two groups all had the IgG and IgA decreased, but the treatment group decreased more significantly. In addition, the treatment group had decreased RF. Conclusion Total glucosides of peony can improve the hypergammaglobulinemia of UCTD.

Objective:To investigate the influence of different routes of administration on vaccine efficiency of peptide-pulsed dendritic cells(DC).Methods:Immunization of syngeneic C57BL/6 mice with bone marrow-derived murine DC pulsed with SIINFEKL, a MHC class Ⅰ-restricted peptide from chicken ovalbumin(OVA) sited at 257-264 amino acid residuals were performed via subcutaneous(s.c.), intramuscular(i.m.), intravenous(i.v.), and intraperitoneal(i.p.) administration, respectively. Seven days later the mice were sacrificed and the splenocytes were prepared to analyze antigen-specific CTL lysis for target cells and IFN-?-producting CD8+T lymphocytes using in vivo CTL assay and intracellular cytokine staining(ICS), respectively.Results:The results from in vivo CTL assay showed that the CTL lysis activities were 37.3%?7.3%, 10.8%?2.3%, 56.9%?3.6% and 61.0%?4.2% via s.c., i.m., i.v., and i.p. administration, respectively. Similarly, ICS showed that IFN-?-producting cells in total CD8+T lymphocytes were 0.43%?0.09%, 0.85%?0.12%, 0.76%?0.14% and 0.15%?0.04%, respectively.Conclusion:Different routes of administration has an obvious influence on vaccine efficiency of peptide-pulsed DC. The i.p. immunization with DC elicites the strongest CTL lysis activity, i.v. immunization is next, and s.c., in particular i.m. is the worst, suggesting that i.p. administration may be a safe and effective route for immunization with peptide-pulsed DC against cancers in a mice model.

Objective To evaluate the influence of granulocyte colony-stimulating factor (G-CSF) on the quantity and ratio of type 1 dendritic cells (DC1) and type 2 dendritic cells (DC2) in normal allogeneic hematopoietic stem cell graft donor peripheral blood (PB) and bone marrow (BM). Methods G-CSF treatment with 10 μg/kg per day for 5 days, the quantity, ratio of DC1 and DC2 in G-CSF primed allogeneic peripheral blood stem cell graft (G-PBSC) were detected in 11 donors, 20 donors in G-CSF primed allogeneic bone marrow stem cell graft (G-BMSC), 8 donors in unprimed PB, and 10 normal individuals in unprimed BM,respectively. by flow cytometry method. Results After treated by G-CSF, the mean BMDC2 was increased from 14.37×106/L to 29.68×106/L ( t = 2.433, P = 0.022) in control group, whereas BMDC1 count did not change (13.77×106/L vs 18.88×106L, t = 1.169, P = 0.251). The ratio of DC2 to DC1 was significantly higher in G-CSF treated donor BM (1.83±0.81 vs 1.12±0.32, t = 2.658, P =0.013). After G-CSF treatment of normal donor, the number of PBDC2 (14.92×106/L vs 26.76×106/L, t = 2.390, P = 0.029), and the ratio of DC2 to DC1 was increased (1.00±0.37 vs 2.02±1.43, t = 2.158, P = 0.044), but the number of PBDC1 was similar (14.21×106/L vs 18.02×106/L, t = 0.625, P=0.541). Conclusion G-CSF treatment of normal allogeneic HSC donor selectively increase the number of PBDC2 and BMDC2, but do not change PBDC1 and BMDC1.

Prospective studies have indicated that the incidence of recurrent stroke in patients with symptomatic intracranial arterial stenosis is approximately 15-20％ per year,and the mortality rate is significantly higher.Although the strict control of the risk factors for atherosclerosis and antithrombotic drugs,especially the use of anti-platelet drugs,is the main basis treatment for these patients,some patients may have drug resistance.These high-riskpatients showed severe stenosis ( ＞ 70％ ) of the recent clinical symptoms of ischemia and theclinical and imaging evidence of distal hemodynamic irnpairment accompanying arterial stenosis.The advances in balloon and stenting have made people begun to consider the possibility ofusing angioplasty and stenting for the treatment of these high-risk patients.However,becausethe relative efficacy of these invasive therapy and drug therapy is not very clear,furtherrandomized clinical trial is still needed.This article reviews the available drug treatment optionsfor symptomatic intracranial arteriosclerotic disease and the current status of endovascudartreatment.
