丹参酮生物合成相关SmERF108转录因子的鉴定及其靶基因分析＊

目的 鉴定与丹参酮合成相关转录因子AP2/ERF家族中SmERF108转录因子，并分析转录因子SmERF108的靶基因。方法 利用生物信息学在线分析平台如NCBI、PFAM等分析SmERF108的序列特征；MEGA-X软件用于构建SmERF108与不同功能转录因子的系统进化树；拟南芥原生质体转化法鉴定SmERF108蛋白的亚细胞定位；通过实时荧光定量PCR（Real-time qPCR）对SmERF108基因在丹参不同器官和组织差异表达进行检测；利用酵母体系对SmERF108的转录激活活性进行探究并用酵母单杂技术确定其靶基因。结果 SmERF108具有典型的AP2/ERF保守结构域，属于ERF-B3亚组，系统进化树和保守基序分析显示SmERF108与丹参中SmERF128、青蒿中AaERF2亲缘关系较近且保守基序分布一致；亚细胞定位显示SmERF108蛋白定位于细胞核；SmERF108基因在周皮中表达最高，且呈现周皮（R1）>韧皮部（R2）>木质部（R3）的规律；酵母自激活验证SmERF108具有转录激活活性，同时酵母单杂交确认其能与关键酶基因SmCPS1启动子结合。结论 鉴定到丹参中一个新转录因子SmERF108，生物信息学分析及差异表达分析预测与丹参酮合成相关，分子互作初步证实靶基因为SmCPS1二萜环化酶。

白藜芦醇对酒精诱导雄性大鼠骨量减少和骨强度降低的保护作用

目的探索白藜芦醇对酒精诱导雄性大鼠骨量减少和骨强度降低的影响。方法 30只12周雄性大鼠随机分为对照组、模型组和治疗组3组,每组10只。模型组和治疗组大鼠给予0.4 mL/100 g的20%乙醇溶液,每周3次。治疗组接受白藜芦醇40 mg/kg治疗,每日一次,治疗为期12周。治疗结束时收集血清和股骨对治疗结果进行评价。结果治疗12周后,治疗组的股骨骨密度较模型组显著升高,差异有统计学意义(P0.05);Mircro-CT显示治疗组大鼠股骨干骺端较模型组具有更多骨小梁以及更佳的骨微观参数,差异有统计学意义(P0.05);生物力学结果显示治疗组股骨的极限载荷和峰值负荷较模型组显著升高,差异有统计学意义(P0.05);而血清检测结果表明治疗组的碱性磷酸酶和骨钙素较模型组明显降低,差异有统计学意义(P0.05)。结论白藜芦醇对酒精诱导雄性大鼠骨量减少和骨强度降低有一定的保护作用。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.     

乳腺癌诊治现状

乳腺癌是妇女中最常见的恶性肿瘤，发病率正逐步上升。美国的发病率已达120／10万，每8位妇女中有1位患乳腺癌。目前我国尚无发病率的确切报告，一些沿海大城市的报告已达40／10万左右，随着经济水平提高、生活方式的改变，发病率还会逐步上升，故该病已得到普遍重视。另一方面，根据美国SEER报告，近30年来乳腺癌的死亡率在美国已呈下降趋势，主要归功于肿瘤的早期发现及综合治疗的改进。

舶来的"四泉利润"

“做个加盟店很不划算，交加盟费、风险金，还要给特许商管理费……”，许多意向加盟商都有这种说法。有些特许商也常说：“开上几十家店，加盟费都赚不过来，自已还可以直营，还有管理费、促销费、培训费……”这正应了“羊毛出在羊身上”这句古话。
