Methods Eighty cases with primary dysmenorrhea due to damp-cold retention were randomly divided into a moxibustion group （40 cases） and a medication group （40 cases）. Moxibustion at Guonyudn （关元 CV 4） and Shiqizhui （十七椎 EX-B 8） was adopted for treatment of the moxibustion group a week before the period, which lasted for 10 days as a treatment course. Fenbid was used as oral administration for three continue menstrual periods for the medication group. The treatment lasted for 3 menstrual periods in two groups. The Cox Menstrual Symptom Scale （CMSS） was adopted to grade the menstrual symptoms, and differences between the two groups were compared. Results The total effective rate of the moxibustion group was 97.5% （39/40）, and the total effective rate of the medication group was 72.5% （29/40）. The effect of the moxibustion group was obviously better than the medication group （P〈0.05）. Before and after treatment the menstrual symptom scores of the moxibustion group were 9.78±1.86 and 2.25±3.33, while the medication group were 9.71±1.64 and 5.31±4.26. The scores of both groups decreased obviously after treatments. And the decreased amplitude of the moxibustion group was much more obvious than that of the medication group （P〈0.05）. Conclusion The effect of moxibustion on primary dysmenorrhea due to damp-cold retention is obvious, which is better than Fenbid.展开更多

The date of the snowfall was about one month earlier than the average. The National Centers for Environmental Prediction (NCEP) reanalysis data, conventional data, and Automatic Weather Station (AWS) data are utilized to explore the reasons for the snowfall and the influencing systems. The main conclusions are as follows: (1) It is revealed from the average geopotential height and average temperature fields at 500 hPa that the large scale circulation in November 2009 was favorable to snowfall. The cold-dry air from West Siberia and the warm-moist air from the Bay of Bengal converged in North China. In addition, it was found from the average moisture flux field at 700 hPa that the main water vapor source was in the Bay of Bengal. (2) Not only the "return current", as usually accepted, but also the inverted trough on the current had an important contribution to the snowfall. The inverted trough could produce the obvious upward motion that is an important environmental condition of snowfalls. (3) More attention should be paid to mesoscale systems such as mesolows during the cold season because of their importance, though they do not occur as frequently as in the warm season. It should be pointed out that AWS data are very useful in mesoscale system analysis during both warm and cold seasons.展开更多

Cold-damp coagulation and stagnation type dysmenorrhea models were established. In group C,mild moxibustion on ＂Shenque（神阙 CV 8） ＂ and＂Guanyuan（关元 CV 4）＂ was carried out from the time after modeling on the 8 th day for 3 consecutive days. In group D, mild moxibustion was given as the same methods with group C after injection with oxytocin on the 11 th day. In group E, mild moxibustion was given as the same methods from the time after modeling on the 8 th day to that after injection with oxytocin on the 11 th day for 4 consecutive days. The writhing behavior and the changes in levels of ET-1 and NO in uterine tissues of rats with dysmenorrhea in each group were observed.Results： Comparison of the latent period： compared with（4.38 ± 1.06） min in group B,the latent period of rats in group C（9.67 ± 1.32） min,group D（11.78 ± 1.30） min and group E（15.00 ± 1.22） min obviously prolonged（all p 0.01）. Compared with group C, the latent period of group E obviously prolonged（p 0.01）. Compared with group D, the latent period of group E obviously prolonged（p 0.01）.Comparison of the writhing times： compared with（4.38 ± 1.06） in group B,the writhing times of rats in group C（9.67 ± 1.32）,group D（11.78 ± 1.30） and group E（15.00 ± 1.22） reduced（all p 0.01）. Compared with group C,the writhing times of rats in group D and group E reduced（both p 0.01）. Compared with group D, the writhing times in group E reduced（p 0.05）.
