??Objective    To investigate the influence of Bushen Zhuanggu Decoction on the bone healing after teeth extraction in osteoporotic dogs. Methods    Totally 9 female adult dogs whose bilateral ovaries were surgically removed to establish osteoporosis models were randomly divided into 3 groups ??control group??Western medicine group and traditional Chinese medicine group??. Bilateral mandibular premolars were extracted 3 months after castration. Osteoporosis treatment was started the third day after tooth extraction. The dogs in the traditional Chinese medicine group??the Western medicine group and the control group were respectively fed with Bushen Zhuanggu Decoction??Estradiol Valerate Tablets and nothing. The bone mineral density??BMD?? value of dog′s lumbar spine and mandible of each group were detected before and after 3 months of castration and 3 months after teeth extraction. The tissue morphology of the mandible was observed at 1??2 and 3 months after teeth extraction. Results    Three months after teeth extraction??the BMD values of the lumbar spine and mandible in the traditional Chinese medicine group and the Western medicine group were significantly increased compared with those before the osteoporosis treatment??and there was no significant difference compared with the preoperative ones. One month after teeth extraction?? the new bone and the trabecular bone were observed in irregular patterns in the control group and the Westen medicine group??and those were arranged in a mesh pattern in the Chinese medicine group. Two months after teeh extraction??the trabecular bone structure was sparse in the control group??the Western medicine group was more than that of the new bone??and the number of trabecular bone in the Chinese medicine group was more robust. Three months after teeth extraction??the bone trabecular structure was relatively compact in the control group and the gap is small??the new bone tissue and the original bone tissue roughly fused together in the Western medicine group??the new bone tissue of the traditional Chinese medicine group was more similar to the structure of the original bone. Conclusion      Bushen Zhuanggu Decoction can make cancellous bone around the teeth extraction of the osteoporosis canine and significantly increase the amount of bone tissue??so as to promote bone reconstruction and bone healing after teeth extraction.     

Dietary exposures and allergy prevention in high-risk infants: A joint statement with the Canadian Society of Allergy and Clinical Immunology

Allergic conditions in children are a prevalent health concern in Canada. The burden of disease and the societal costs of proper diagnosis and management are considerable, making the primary prevention of allergic conditions a desirable health care objective. This position statement reviews current evidence on dietary exposures and allergy prevention in infants at high risk for developing allergic conditions. It revisits previous dietary recommendations for pregnancy, breastfeeding and formula feeding, and provides an approach for introducing solid foods to high-risk infants. While there is no evidence that delaying the introduction of any specific food beyond six months of age helps to prevent allergy, the protective effect of early introduction of potentially allergenic foods (at four to six months of age) remains under investigation. Recent research appears to suggest that regularly ingesting a new, potentially allergenic food may be as important as when that food is first introduced.

林洁从“阳化气,阴成形”论治多囊卵巢综合征

多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者的卵泡发育异常与"阳化气,阴成形"功能失衡密切相关。在PCOS患者的月经周期变化中,"阳化气"与"阴成形"的功能失调常见两种阴阳失衡表现。其一是"阴成形"不足,"阳化气"相对过盛;其二是"阴成形"太过,"阳化气"乏力。林洁教授将PCOS患者从胖、瘦两种体型辨证施治,瘦型PCOS患者的发病之本为"阳化气"太过,其标为"阴成形"不足,多辨为心肝火旺证,采用以丹栀逍遥散为基础方化裁的多囊Ⅰ号方治疗;胖型PCOS患者发病之本为"阳化气"乏力,其标为"阴成形"太过,采用以导痰汤为基础化裁的多囊Ⅱ号方治疗。另外,属患者养成健康的饮食习惯和良好的生活习惯,选择适合的运动方式,病情严重者进行必要的心理疏导。
