OBJECTIVE: To investigate the optimizing conditions in isolation of the side population in laryngeal carcinoma cell line Hep-2. METHOD: Single-cell suspension cells were detached from the culture flask with trypsin EDTA, at a concentration of 1 x 10(6) cells/ml. (1) The trail Samples were incubated with Hoechst33342 at a concentration of 5 microg/ml, 9 microg/ml, 10 microg/ml, 11 microg/ml for 90 minutes. (2) They were incubated with Hoechst for 50, 70, 90, 110, 130 min in water bath individually. (3) The single-cell suspension were incubated Hoechst in water bath and in thermostat each. (4) The two different density of cells were harvested, which were 100% and 70%, and then di gest into single-cell suspension. Once incubation finished, suspended in phosphate buffered saline (PBS), then test SP% by flow cytometry. Among all groups,Verapamil hydrochloride was added to the control samples, incubated at 37 degrees C for 30 minutes, the other condition were keep the same with their trial groups. RESULT: (1) The percentage of Hoechst-negative cells in trial group was (39.96 +/- 0.24)%, (26.23 +/- 0.39)%. (18.79 +/- 0.02)%, (19.01 +/- 0.14)% at the concentration of 5 microg/ml, 9 microg/ml, 10 microg/ml, 11 microg/ml respectively, when the PI-positive cells were (30.45 +/- 0.63)%, (49.9 +/- 0.42)%, (50.12 +/- 0.68)%, (64.16 +/- 0.39)% separately. (2) Varying the duration of staining incubation showed that there was a typical FACS pattern and SP% was constant when the incubation was at least 90 min. (3) Compare to water bath, SP% was more than in thermostat, the SP% was (18.67 +/- 0.45)%, (22.6 +/- 0.50)% respectively; (4) Cell density is also responsible for SP%. The low density the cell is, the less in SP%. SPSS13.0 was used in statistical analysis, the groups were compared using t-Test. P < 0.05 was considered statistically significant. CONCLUSION The optimum concentration and duration of incubation of Hoechst33342 in isolation of the side population cells in laryngeal carcinoma cell line Hep-2 is 10 microg/ml and 90 min. Incubated in water bath is better than in thermostat. The best staining cell density is around 80%-90%.

OBJECTIVETo observe the difference in clinical efficacy on focal vitiligo treated with heat-sensitive moxibustion in comparison with medication, and discuss its effect mechanism.

METHODSSixty-eight cases were randomized into a moxibustion group (38 cases) and a medication group (30 cases). Additionally, 20 healthy persons were selected randomly as a normal group. In the moxibustion group, the heat-sensitive moxibustion was applied to Hegu(LI 4), Quchi(LI 11), Yanglingquan(GB 34), Zusanli(ST 36), Xuehai(SP 10) and the others, once a day. In the medication group, triamcinolone acetonide cream was used externally and locally, twice a day. In the two groups, the treatment of 15 days made one session. The efficacy was observed after continuous treatment for 3 sessions. The hemorheology test was done in all of the subjects. The radioimmunoassay was adopted to determine the levels of Interleukin 2 (IL-2), Interleukin 6 (IL-6), Interleukin 10 (IL-10) and tumor necrosis factor (TNF-alpha) before and after treatment.

RESULTSThe levels of IL-6, IL-10 and TNF-alpha in vitiligo patients were higher significantly than those in the normal group (P<0. 01, P<0. 05), the level of IL-2 was lower significantly than that in the normal group (P<0. 01) before treatment. After 3 sessions treatment, IL-2 level was increased significantly in the moxibustion group and the levels of IL-6, IL-10 and TNF-alpha were reduced, without significant differences as compared with the normal group (all P>0. 05). But the differences were significant as compared with those in the medication group (all P<0. 05). The curative and remarkably effective rate was 76. 3% (29/38) after treatment in the moxibustion group, which was higher significantly than 13. 3% (4/30, P<0. 05) in the medication group.

CONCLUSIONHeat-sensitive moxibustion achieves very good clinical efficacy on focal vitiligo, which is probably via promoting blood circulation and regulating the levels of IL-6, IL-10 and TNF-alpha.

This paper investigate the methods to detect engraftment rate of the four patients with hematological disorders who accepted nonmyeloablative allogeneic peripheral blood stem cell transplantation(NAPBSCT). To find out the best method, their engraftment rates were detected serially at different time after NAPBSCT by means of either FISH, or conventional chromosome analysis combined with R-banding analysis concurrently.The results were carefully compared with one another. All these four sex-mismatched cases were engrafted partially,and two of them changed to full engrafment. The results show no statistically significant difference in 3 groups (conventional method, FISH for hypermetaphase, FISH for interphase nuclei). But the results strongly indicate that FISH is a rapid, precise, objective,and reliable menthod for detection of the engraftment rate,and it is suitable for sex-mismatched NAPBSCT.

Reviewing the literatures about adverse reactions induced by traditional Chinese medicine injections (TCMI) reported on CNKI from 1983 to 2013. Analyzing the causes of adverse reactions induced by TCMI from its quality standards. Provide ideas for improving security of TCMI and completing its quality standards. This review indicates that TCMI-induced adverse reactions have little relationship with the number of compositions, but have tight connection with chemical ingredients and solvents. Adverse reactions can be decreased by perfecting the quality standards of TCMI.
