This article summarizes and analysis the rules of acupoint selection in the treatment of dysmenorrhea.Method:Computer retrieval and manual search were combined to look for domestic literature on dysmenorrhea treated by acupuncture and moxibustion in year 2003 to 2011.There were altogether 20 qualified articles,concerning 28 acupoints.The above results showed that in the treatment of dysmenorrhea,the commonly used points are distributed in Ren,spleen meridian of foot-Taiyin,foot Yangming meridian and foot Taiyang meridian.Specific acupoints was the main type for selecting points.

The "opening-closing-pivoting" theory on the six meridians is one of the difficult points in the study of Shang Han Lun (Treatise on Cold Diseases). The authors give an explanation on the space and time differentiation of three-yin and three-yang as well as the "opening-closing-pivoting" theory based on the predecessor's experience, and then analyze the physiological and pathological characteristics of the six-meridian disorders.

Objective To investigate p16 promoter methylation in premature rats with chronic lung disease induced by hyperoxia. Methods Eighty premature Wistar rats were randomly divided into two groups: hyperoxia group (fraction of inspiratory oxygen) 0. 90 and control group (fraction of inspiratory oxygen 0. 21), 40 rats for each group. Semi-nested methylation specific polymerase chain reaction and methylation specific polymerase chain reaction were applied respectively to detect p16 promoter methylation in lung tissues. Additionally, p16 mRNA and protein expressions in lung tissue were detected by reverse transcription- polymerase chain reaction, Western blot and immunohistochemistry method. Results The methylation was not found in control group by seminested methylation specific polymerase chain reaction and methylation specific polymerase chain reaction, while was found in different aged rats of the hyperoxia group. The methylation detection rate was higher by using the semi-nested methylation-specific polymerase chain reaction (52.5%, 21/40) than that by methylation specific polymerase chain reaction (42.5%, 17/40) in the hyperoxia group,but there was no statistically significant difference between the two methods. The p16 mRNA in the hyperoxia group were significantly lower than in the control group at day 7, 14 and 21(1.73 ± 0.40 vs 2.11±0. 37,1.29±0. 19 vs 1.60±0. 27,0. 95±0.25 vs 1.72±0. 34, t=2.19, 2.95 and 10. 43,P＜0. 05). The p16 protein expressions by western blot in the hyperoxia group were significantly lower than in the control group at day 7, 14 and 21 also (88. 1±8. 7 vs 95.0±4.1,65.7±4.5 vs 83. 5±13.6 and 50.4±4.9 vs 86.7±11.9, t=2.27,3.95 and 13.40,P＜0.05). The expression of p16 mRNA (1.06±0.61) and protein (62.32±25.65) in lung tissues of rats with methylation was lower than that without methylation (1.63±0.62 and 94.93±22.21, respectively) (t=2.95, OR=0. 86;t=4.28, OR=0. 85,P＜0.01, respectively). Conclusions Exposure to hyperoxia might induce p16 promoter methylation in lung tissues in premature rats. Methylation risk increases as exposure time extends. p16 promoter methylation induced by hyperoxia might participate in the mechanism of lowering p16 mRNA and protein expression, but might not result in p16 gene silence.

The time of six meridians diseases tending to be cured in Shang Han Lun (Treatise on Cold Diseases) is always one of the key points for study, but up till now no satisfied explanations are made. The authors try to study it on the basis of the theory of "three-yin and three-yang" according to the relationship between human body and the environment.

To explore the laws in syndrome differentiation of Taiyang disease and the prescriptions and herbs used in its treatment in Shanghan Lun (Treatise on Febrile Diseases).

In order to explore the dose-response patterns of Gancao (Radix Glycyrrhizae) in Shanghan Lun (Treatise on Febrile Diseases), all prescriptions containing Gancao in Shanghan Lun were analyzed by frequency and hierarchical clustering analysis. The doses of Gancao used in Shanghan Lun ranged from six zhu (Chinese unit, and one zhu is equal to 0.65 g) to four liang (Chinese unit, and one liang is equal to 15.625 g). Doses of one, two, three or four liang were commonly used. One liang Gancao as juvantia was usually matched with Mahuang (Herba Ephedrae), Xingren (Semen Armeniacae) and Guizhi (Ramulus Cinnamomi) for restricting the excessive diaphoresis of Mahuang. Two liang Gancao was often matched with some couple drugs, such as Guizhi and Shaoyao (Radix Paeoniae), Shigao (Gypsum Fibrosum) and Zhimu (Rhizoma Anemarrhenae), Fuzi (Radix Aconiti Lateralis) and Ganjiang (Rhizoma Zingiberis), for warming yang to supplement qi, nourishing yin, detoxifying Fuzi, and preventing qi impairment from heat evil. Three liang Gancao was mainly matched with Banxia (Rhizoma Pinelliae) or Renshen (Radix Ginseng) for treating middle energizer emesis. Four liang Gancao was matched with Ganjiang or tonifying herbs for invigorating vital qi and relieving spasm in deficiency syndromes with contraction, palpitation or diarrhea. Gancao is used for treating many syndromes in Shanghan Lun. It is frequently used to treat excess or heat syndromes with one or two liang in a dose and deficiency or cold syndromes with three or four liang in a dose.
