[Objective (The objective of this study is to elucidate the allopathic effects of walnut leaves aqueous extracts on 4 medicinal plants! =citis tinDoria L. ，Atractylodes macrocephal Koi(dz. ，Poly^^ala tenuifolia Willd. and Sa;— 2;—a Bge. )，and provide a theoret¬ical basis for the intercropping between the Chinese herbs and forest. ' Method】 By using bio-assay method ， the allopathic effects of walnut (Juglans repif L. . leaves aqueous extracts were investigated on the seed germination， seedling growth and fresh weight of 4 medicinal plants. ' Result】 The results showed that the aqueous extracts of walnut leaves existed different allopathic cffects on different test medicinal plants. All aqueous extracts significantly inhibited the germination capacity of = tincDria. ，but for A. macrocephala，there existed inhibito¬ry/ stimulatory effects on the germination rate，and P. Willd. had good adaptability during the seed germination process under the aqueous extracts of walnut leaves. The root length were more sensitive than shoot length to the water-soluble allelochemicals of walnut leaf aqueous ex- tracts，the inhibitory effect of root lengtli of S. miltiorrhiza. was more enhanced with the concentrations increasing of walnut leaves aqueous extracts. 'Conclusion】The studies suggested that there existed different effects with concentration of walnut leaf extracts and receptor plant species，so allelopathic effects exhibited different selectivity and specificity. We preliminarily suggest tliat Polygala tenuifolid Will(d could be used as a suitable medicinal material for walnut intercropping [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to understand the influence of planting years on the soil fertility characteristics of wine vine-yards at the eastern foot of Ilelan mountain in Ningxia, and to provide a basis for the sustainable development of wine industry. [Method] vineyard rhizosphere soil and non-rhizosphere soil of 3 years,8 years and 20 years were collected from Ganchengzi district of Qingtongxia city at the eastern foot of Helan mountain in Ningxia, and soil fertility variation characteristics were measured. [Result] The pH value and electrical conductivity of grape rhizosphere soil were higher than that of non-rhizosphere soil regardless of the planting years. The total N, total K, organic carbon and available K in grape soil were increasing first and then decreasing under different planting years. The average content of total N, total K, organic; carbon and available K were the highest at 8 years. The content of alkaline N, available F and total P in grape soil increased with the planting years. There was no significant difference in microbial biomass C, N and P in grape rhizosphere soil and non-rhizosphere soil between 3 years and 20 years. [Conclusion] With the increase of planting years, nutrient enrichment rate in root zone was weaker and weaker, but the soil fertility was accumulated in the vineyard with the planting years.

Objective: To study the expression of ubiquitin-like with PHD and ring finger domains 1(UHRF1) protein in ovarian cancer tissue and the effect of UHRF1 on the proliferation and invasion of ovarian cancer cells. Methods: Ovarian cancer tissue and adjacent normal tissue were collected, the expresion of UHRF1 protein were detected by Westerrn blot. Ovarian cancer SKOV-3 cell was cultured in vitro, UHRF1 si RNA and negative control si RNA were transfected. Then the cell viability was assayed by CCK-8 kit, cell invasion capability was assayed by Transwell. Expressions of Cyclin D1, CDK6, MMP2 and MMP9 m RNA were assayed by FQ-PCR.Re sults: The expression of UHRF1 protein in ovarian cancer tissue was higher than that in adjacent normal tissue. The cell viability of SKOV-3 cells and number of migrated cells transfected by UHRF1 si RNA was significantly lower than that of SKOV-3 cell transfected by negative control si RNA, the expressions of Cyclin D1, CDK6, MMP2 and MMP9 m RNA were significantly decreased. Conclusions:The expression of UHRF1 protein was significantly increased in ovarian cancer; UHRF1 could promote the proliferation and invasion of ovarian cancer cell. [ABSTRACT FROM AUTHOR]

Septate uterus is the most common type of the congenital female genital tract malformation．However, clinicians are often confused by questions about its diagnosis and treatment. For example, what is the gold standard for the diagnosis? Is it possible that the outer shape of fundus of the uterus is abnormal? What are the indications for surgery of septate uterus (especially for those with shallow septa)? Which is the best way to monitor during the surgery of transcervical resection of septum (TCRS)? Is L-hook electrode or loop-shaped electrode used during TCRS? When can you make a correct judgment that the whole septum has been resected? During TCRS, if the lateral wall of the uterus convex to the uterine cavity, does it need simultaneous metroplasty? Whether or not an intrauterine device is needed to prevent postoperative intrauterine adhesion or the estrogen therapy is needed postoperatively to promote endometrial growth? What is the common cause of massive vaginal bleeding postoperatively? Different answers to those questions may directly affect the clinical decision-making of clinicians, and may also lead to misunderstanding of gynecologists. In the present article, we dedicate to reach a consensus related to the above questions. [ABSTRACT FROM AUTHOR]
