Intraoperative frozen section pathology of vaginal margin in radical hysterectomy on the prognosis and quality of life for patients with IB2-IIA2 cervical cancer: study protocol for a multicenter randomized controlled trial.

Background: Several risk factors have been identified that compromise the treatment outcome in patients with early-to-mid-stage cervical cancer (CC) who are primarily treated with radical surgery. However, there is no report on the impact of intraoperative frozen pathology examination of vaginal margins on the prognosis of patients with CC. This study aimed to conduct a randomized controlled trial (RCT) to determine whether selective vaginal resection can reduce the incidence of operative complications and the risk of postoperative radiotherapy.

[Application of video endoscopic inguinal lymphadenectomy in radical vulvectomy for carcinoma].

Objective: To evaluate the feasibility and safety of applying video endoscopic inguinal lymphadenectomy via hypogastric subcutaneous approach (VEIL-H) in the treatment of vulvar carcinoma.

Methods: From September 2009 to December 2012, 15 patients with vulvar carcinoma underwent VEIL-H plus radical vulvectomy at many participating hospitals.

Results: All were treated surgically.

[Effects of cultivation technique on yield and favonoid content of Chrysanthemum flower (Qiju) grown in Hebei].

Objective: To study the effect of cultivation techniques on the flower yield flavonoid content in Chrysanthemum flower grown in Hebei.

Method: Studied on flowers yield and three factors (transplanting date and plant density and fertilizer quantity) were examined in field experiment at 4 treatments levels.

Result And Conclusion: The best results were obtained at following conditions: diammonium phosphate 300 kg x hm(-2) and potassium sulfate 150 kg x hm(-2) fertilized before transplanting, transplanting at the first ten days of May and the spacing 40 cm x 40 cm.
