RESUMEN
In this paper， the name， classification， origin and other aspects of Schizonepetae Herba in the famous classical formulas were researched by referring to the related herbal literature， medical books and prescription books in the past dynasties. The results showed that Schizonepetae Herba first appeared in Shennong Bencaojing （《神农本草经》） as Jiasu， while Jingjie first appeared in Wupu Bencao （《吴普本草》）， and the name of Jingjie was mainly used as the rectification of name in later generations. The name of Jiasu is mostly derived from its smell， and the name of Jingjie is mostly derived from its pronunciation. Schizonepeta tenuifolia has been highly praised in the past as a original material， and its genuine producing area is Jiangsu， Hebei and other places， medicinal part is whole herb with spike. In modern times， the quality of Schizonepetae Herba is best described as having thin stems， green spike， and aroma. In clinical application， the raw products of Schizonepetae Herba is mainly used， and the carbonisata is mainly used for hemostasis. Famous classical formulas of Huaihuasan and Danggui Yinzi are all made of Schizonepetae Spica， so it is recommended to use the dried panicle of S. tenuifolia. In Liangxue Dihuangtang， Schizonepetae Herba Carbonisata is used， therefore， it is suggested to adopt the processing method of Schizonepetae Herba Carbonisata in the 2020 edition of Chinese Pharmacopoeia.
RESUMEN
Ephedrae Herba is a commonly used medicine for dispersing wind and cold， which has a long medicinal history. By referring to the herbal literature， medical books and prescription books， this paper intends to carry out herbal textual research on the name， origin， medicinal part， producing area， harvesting and processing methods of Ephedrae Herba in famous classical formulas， in order to provide the basis for the development of relevant famous classical formulas. According to textual research， the main base of ancient Ephedrae Herba was Ephedra sinica. The medicinal part is the herbaceous stems of Ephedrae Herba. Before the Northern and Southern dynasties， the origin of the records was Jindi and Hedong， which is now Shanxi province. In the Northern and Southern dynasties and later generations， the producing area expanded， and now it is mainly distributed in Hebei， Shanxi， Shaanxi， Inner Mongolia， Gansu， Liaoning and other places， among which Inner Mongolia is the main producing area. The harvesting and processing methods in the past dynasties are to harvest the stems in autumn， dry them in the shade or air to 70%-80% dry， and then dry them in the sun. The processing methods in the past dynasties mainly include removing the knots， wine-fried， honey-fried， processing with vinegar and so on， at present， only honey-fried is still in use. Based on the research results， it is suggested that Ephedrae Herba in famous classical formulas should be selected the dry herbaceous stems of E. sinica. If the processing requirements are not indicated， it is suggested to use raw products of Ephedrae Herba.
RESUMEN
[Objective]To determine the relationship between maternal serum IL-1, IL-6, IL-8, TNF-a and CRH levels and preterm labor in asymptomatic women at 24 to 28 weeks' gestation. [Methods] We performed a prospective cohort study from January 2015 to December 2017 for asymptomatic women at 24 to28 weeks' gestation and maternal serum. According to the pregnancy outcome, 100 cases of preterm labor were selected as experimental group and another 100 cases of term labor as control group. The levels of serum IL-1, IL-6, IL-8, TNF-a and CRH were measured by ELISA. The partial membranes of all cases were examined pathologically after labor. [Results] The levels of serum IL-1, IL-6 and IL-8 in preterm labor group were significantly higher than those in the control group (P <0.05). The levels of serum IL-6and IL-8 in preterm labor with chorioamnionitis were significantly higher than those without chorioamnionitis and term labor (P < 0.05). The level of IL-1 in preterm labor without chorioamnionitis was significantly higher than that of term labor (P<0.05). The levels of serum TNF-a and CRH had no difference between the groups (P>0.05). Receiver-operating characteristic curves demonstrated that serum IL-1, IL-6 and IL-8 predicted preterm labor. The area under the curve (AUC) of IL-1 was 0.843. The AUC of IL-6 was0.675 and IL-8 was 0.55. [Conclusion] Maternal serum IL-1, IL-6 and IL-8 in asymptomatic women at24 to 28 weeks' gestation are useful markers for prediction of preterm labor.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the distribution of tetracycline-arginine-glycine-aspartate-tyrosine (T-RGDY) in mice and its effect on bone.</p><p><b>METHODS</b>125-labeled T-RGDY was studied for its distribution in mice and for its effects on bone by histomorphometry in ovariectomized rats.</p><p><b>RESULTS</b>The 125I-labeled T-RGDY was more concentrated in the osteoporotic bone than in the normal bone. Compared with ovariectomy group, the morphologic index such as trabecular bone volume/total tissue volume (TBV/TTV), TBV/sponge bone volume (SBV), and mean trabecular plate thickness (MTPT) in T-RGDY group significantly increased (P < 0.05). As compared with sham operation group, MTPT significantly increased in T-RGDY group (P < 0.05), while TBV/SBV and mean trabecular plate density significantly decreased (P < 0.05), and TBV/TYV and mean trabecular plate spacing were almost the same as those in sham operation group (P > 0.05).</p><p><b>CONCLUSION</b>T-RGDY may concentrate in bone tissue to a certain degree, which is closely related with the status of bone remodeling. T-RGDY may inhibit the bone loss caused by ovariectomy.</p>
