OBJECTIVETo explore the relationship between the temperature and time in moxa cone moxibustion with different purities of moxa.

METHODSAccording to the purities, the moxa were divided into a 10 : 1 group, a 20 : 1 group, a 30 : 1 group and a 40 : 1 group, 30 moxa cones in each group. With the VICTOR DM6902 electronic thermometer, the temperature of the undersurface center at different time points during the moxa cone moxibustion with different purities of moxa was measured. Once the moxa cone was ignited, the results were recorded at the end of each second. Also the temperature peak of the undersurface center and the time when the peak occurred were recorded.

RESULTThe undersurface temperature was increased in all the groups; the time of moxa cone reaching the lowest peak temperature was significantly different in all the groups (all P<0. 05), which was the 10 : 1 group, 20 : 1 group, 30 : 1 group and 40 : 1 group from slow to fast. 50 s, 60 s, 70 s, 80 s and 90 s after moxa cone was ignited, the temperature of moxa cone at the same time point was significantly different in all the groups (all P<0. 05), which was the 10 : 1 group, 20 : 1 group, 30 : 1 group and 40 : 1 group from slow to fast. Conclusion Among the moxa with purity of 10 : 1, 20 : 1, 30 : 1, and 40 : 1, the temperature change rate of the low-purity moxa cone is smaller than that of higher purity, and the stimulating duration of the former is longer than the latter. It is believed that the moxa with purity of 40 : 1 is suitable for scarring moxibustion; the moxa with purity of 30 : 1 and 20 : 1 is suitable for the non-scarring moxibustion; the moxa with purity of 10 : 1 is suitable for gentle moxibustion therapy. The high-purity moxa can also be applied to the field of the low-purity moxa.

Objective To study the expressions of survivin and caspase-9 in human primary hepatocellular carcinoma(HCC) tissues and their relationship with apoptosis.Methods Immunohistochemical staining was uesed to detect the expressions of survivin and caspase-9 in paraffin sections of 96 cases including 42 HCC tissues,42 paired adjacent noncancerous tissues and 12 normal liver tissues. Apoptosis was detected by TUNEL.Results No immunoreactivity of survivin was seen in normal liver tissues.The positive rates of survivin in HCC and paired adjacent noncancerous tissues were 73.81% and 4.76%,respectively,there was significant difference between two groups(P0.05).The expressions of survivin and caspase-9 in HCC tissues were not associated with age,sex and the size of tumor,but they were directly associated with tumor histological grade and metastasis.Conclusion High expression of survivin in HCC may inhibit apoptosis through depressing the expression of caspase-9,and it is an indicator of independent poor prognosis.

Objective To create new tetraploid resource of Dioscorea zingiberensis in the hope of potential breeding materials with high yield and high level of diosgenin. Methods Callus with tiny green buds were directly soaked in colchicine solution or cultured in medium plus with colchicine to prohibit the isolation of chromosomes and induce tetraploid mutants. Results Tetraploids were achieved successfully. The most efficient treatment for inducing tetraploid was soaking the tiny buds in 1?103 mg/L colchicine solution for 24 h, the inducing rate could be up to 35. 2%. The induced tetraploids exhibited notable difference with common wild type (diploids) in morphology, physiology, and microscopic structure. ConclusionThe tetraploid plants show the advantages of gigantic size and vigorous growth. Thus, the established technique system to induce tetraploid from tissue cultured callus would provide an efficient alternative pathway for medicinal plants of Dioscorea L. breeding.
