Guizhi Fuling capsule is a traditional Chinese medicine composed of five kinds of medicinal plants, Cinnamomi Ramulus, Poria, Moutan Cortex, Persicae Semen, and Paeoniae Radix Alba. Pharmacology studies have shown that Guizhi Fuling capsule has many activities: anti-inflammatory, analgesic, anti-tumor, regulating smooth muscle, endocrine regulation and enhancing immunity. It achieved obvious effects in the treatment of uterine fibroids, pelvic inflammatory disease, dysmenorrheal, endometriosis, ovarian cysts, breast hyperplasia and other gynecological diseases. This paper reviewed the main progress on studies of pharmacological activities and clinical applications of Guizhi Fuling capsule in recent years.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

The aim of this study was to investigate the anti-inflammatory effect of Guizhi Fuling capsule and its active complex (consistent of 15 active compounds) on LPS-induced RAW264. 7 cells. The effect of Guizhi Fuling capsule and its active complex on cell viability in RAW264. 7 cells were determined by MTT assay. The inhibitory effect of Guizhi Fuling capsule and active complex on the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells was detected by ELISA assay. The expression of IL-1β and mPGES-1 in Guizhi Fuling capsule or active complex treated RAW264. 7 cells was examined by Western blot assay. Guizhi Fuling capsule and active complex showed no significant effect on the cell viability in RAW264. 7 cells at doses range from 12.5 to 400 mg x L(-1). Compared with LPS treated group, Guizhi Fuling capsule and active complex dose dependently reduced the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells. Moreover, the expression of IL-1β and mPGES-1 was decreased after Guizhi Fuling capsule and active complex treatment, which might contribute to the inhibitory effect of Guizhi Fuling capsule in the releasing of IL-1β, TNF-α and PGE2. This study provided the evidence that Guizhi Fuling capsule and active complex remarkably inhibited the releasing of IL-1β, TNF-α and PGE2induced by LPS in RAW264. 7 cells by reducing the expression IL-1β and mPGES-1. This study provided an experimental basis of Guizhi Fuling capsule for the treatment of inflammation and a theoretical basis for the development of effective compounds of Guizhi Fuling capsule.

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

Objective To compare the clinical effect of total laparoscopic and open liver resection for tumors in segments Ⅶ and Ⅷ.Methods The clinical data of patients with tumors in segments Ⅶ and Ⅷ of the liver who met the inclusion criteria and received operation at Affiliated Hospital of Nantong University from January 2011 to January 2015 were retrospectively analyzed.Among these patients, there were 17 cases who received total laparoscopic liver resection (LLR group), and 25 cases who received open liver resection (OLR group).Results LLR group has obvious advantages in aspects of the level of serum alanine transaminase (ALT) on 1st and 3rd day postoperation, the time anal exsufflation, the drainage volume of abdominal cavity in 3 days after operation and the postoperative hospital stay than those in OLR group (respectively t =-3.075,-3.175,-2.499,-2.088,-2.419, all P < 0.05).There were no significant differences in blood transfusion rate, the resection margin to the tumor, the postoperative morbidity and the total medical cost between the two groups (x2 =1.437, t =-1.244, x2 =0.209, t =1.079, all P > 0.05).Though the mean operative time and intraoperative blood loss of LLR group compared with OLR group increased obviously (respectively t =3.360, 2.189, all P < 0.05).During the postoperative follow-up, there were no significant differences in the postoperative recurrence rate and the long-term survival rate in patients with malignant tumors (respectively x2 =0.240, 0.000, all P > 0.05).Conclusion The therapeutic effect of total laparoscopic and open liver resection are equal in segments Ⅷ and Ⅷ hepatectomy, while, LLR has advantages of less trauma.
