1.The rules of acupoint selection in the treatment of dysmenorrhea
International Journal of Traditional Chinese Medicine 2012;34(7):633-635
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.

Journal of Integrative Medicine 2008;6(12):1294-6
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.

Objective To investigate how to optimize the protocol of embryo cryopreservation to improve the success of frozen-thawed embryo transfer (FET), reduce multiple pregnancy rate and increase the cumulative pregnancy rate from one oocyte retrieval process. Methods The clinical data of 1 166 FET cycles were retrospectively analyzed and separated into different groups:445 for vitrification and 721 for slow-freezing. The vitrification group was divided into single embryo (28 cy?cles), double embryos (71 cycles) and triple embryos (346 cycles). 0-1 optimal embryo was called O0-1 group (235 cycles), 2 optimal embryos were called O2 group (80 cycles), 3 optimal embryos were called O3 group (130 cycles). The difference preg?nancy outcomes (implantation rate, clinical pregnancy, abortion rate and live-birth rate) were compared between groups. Results (1) There were significantly higher embryo survival rate(98.3%vs 73.1%), embryo recovery rate without damaging (83.3%vs 62.1%), implantation rate(36.8%vs 29.9%), clinical pregnancy(57.1%vs 44.0%) and live-birth rate(47.9%vs 34.5%) in vitrification group than those of slow freezing group(P<0.05). (2) There were significantly higher clinical pregnan?cy rate(62.7%vs 39.4%vs 32.1%), multiple pregnancy rate(37.6%vs 10.7%vs 0%)and live-birth rate(52.6%vs 31.0%vs 21.4%)in triple embryos group than those of the single and double embryos groups (P<0.05). (3) There were significantly higher implantation rate(33.0%vs 27.1%), clinical pregnancy(65.2%vs 48.1%), multiple pregnancy rate(38.0%vs 20.4%) and live-birth rate(56.2%vs 39.2%) in O2-3 group than those of O0-1 group(P<0.05). (4) There were significantly higher im?plantation rate(36.8%vs 26.3%) and multiple pregnancy rate (46.7%vs 21.3%) in O3 group than those of O2 group (P<0.05). There were no significant differences in clinical pregnancy(69.2%vs 58.8%), abortion rate(15.6%vs 10.6%), ectopic preg?nancy rate(0 vs 0), live-birth rate(58.5%vs 52.5%) and preterm birth rate(26.3%vs 14.3%) between two groups (P>0.05). Conclusion Vitrification technology can improve the clinical pregnancy and live-birth rate, and decrease multiple preg?nancy rate. Two optimal embryos in one tube are supposed to be the preferred method for embryo cryopreservation.
9.Study on the effects of electrolyzed oxidizing water in root canal treatment
Journal of Practical Stomatology 2000;0(06):-
Objective: To clinically evaluate the efficacy of electrolyzed oxidizing water (EOW) as a root canal irrigation solution on disinfecting bacteria and removing the smear-layer to keep the non-bacterium state in the root canal. Methods: In the first experiment, 108 single-rooted teeth that needed root canal treatment were randomly divided into two groups. EOW was used as the root canal irrigation solution in the experimental group while 30 ml/L H2O2, saline solution, and 75 g/L EDTA solution were used as controls. Bacteriological examinations were conducted from each tooth before and after treatment with the root canal irrigation solutions. In the second experiment, the 20 fresh human extracted teeth were divided into two groups and treated as same as the first experiment in root canal preparation and irrigation. After irrigation, the apical canal wall was observed using SEM. Results: There was no significant difference in bacterial growth and removing the smear layer between the group using EOW and that using saline solution, 30 ml/L H2O2 and 75 g/L EDTA solution. Conclusion:The results indicate EOW is useful as a clinical root canal irrigation solution.
