2.Management of symptomatic intracranial atherosclerotic disease
International Journal of Cerebrovascular Diseases 2011;19(9):708-713
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.
3.Possible Ethical Problems about the Application of Mitochondrial Replacement Technique on Human Reproduction
Chinese Medical Ethics 2016;29(2):268-270
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.

5.Influence of granulocyte colony-stimulating factor on dendritic cells in donor of allogeneic hematopoietic stem cell grafts
Journal of Leukemia & Lymphoma 2011;20(7):415-417
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.

China Pharmacy 2016;27(23):3181-3183,3184
OBJECTIVE:To provide reference for rational use of TCM injection in the clinic. METHODS:The utilization of TCM injections in 34 hospitals from Nanjing area during 2012-2014 was analyzed statistically in respects of consumption sum, DDDs,DDC. The occurrence of ADR induced by TCM injections was also analyzed statistically in the First Affiliated Hospital of Nanjing Medical University. RESULTS:The consumption sum of TCM injections in 34 hospitals from Nanjing area during 2012-2014 increased year by year;top 10 kinds of TCM injections mainly were anti-tumor drugs and cardio-cerebrovascular drugs in 2014,and each of them involved 4 categories and their consumption sum accounted for 46.08% and 32.59%,respectively. Total consumption sum of anti-tumor TCM injections increased slowly,while those of cardio-cerebrovascular drugs,antibiosis and anti-phlogosis increased rapidly. Lentinan injection steadily took up the top in the list of consumption sum and DDDs of single type,its DDC was the lowest and B/A=1.00. In the First Affiliated Hospital of Nanjing Medical University,most of ADR was induced by Xiyanping injection (27 cases,45.00%). CONCLUSIONS:The type of TCM injections keep stable in 34 hospitals from Nanjing area during 2012-2014,mainly involving anti-tumor drugs and cardio-cerebrovascular drugs which were used widely. Clinic should strengthen dialectial therapy close monitoring and attch improtance to the rational use of TCM injections.

China Pharmacy 1991;0(05):-
OBJECTIVE:To determine serum concentrations of phenbarbital(PB),phenytoin sodium(PHT),carbamazepine(CBZ)by micellar electrokinetic capillary chromatograph(MEKC).METHODS:The determination was performed on elastic quartz column(37 cm?50 ?m)with barbital as internal standard.The buffer solution consisted of 10 mmol?L-1 phosphate sodium buffer-30 mmol?L-1 SDS sodium(micellar phase)-15% methanol at a constant voltage of 18 kV.The detection wavelength was set at 210 nm.RESULTS:The linear concentration ranges of PB and PHT were 2.5~80 ?g?mL-1,with detective concentration of 0.1 ?g?mL-1;the linear range and detective concentration of CBZ were 1~32 ?g?mL-1 and 0.2 ?g?mL-1,respectively.The average recoveries of the PB,PHT,and CBZ were 99.90%,99.91%,and 99.42%,respectively.CONCLUSION:The method is rapid,simple,accurate,sensitive and reproducible,and suitable for clinical monitoring of drug level and pharmaceutical study.
9.Influence of different routes of administration on vaccine efficiency of peptide-pulsed dendritic cells
Chinese Journal of Immunology 2000;0(11):-
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.
