[Literature research and status analysis on clinical application of Guizhi Fuling Formula].

Guizhi Fuling Formula was first seen in Synopsis of Golden Chamber by ZHANG Zhongjing. It is composed of Cinnamomi Ramulus, Poria, Moutan Cortex, Persicae Semen, Peony and other drugs, commonly used in the treatment of gynecological diseases such as hysteromyoma, ovarian cyst, endometriosis, pelvic inflammation, dysmenorrhea, etc. In addition, it is also used in internal medicine and urology. This reflects the modern doctors' recognition of the famous prescriptions in ancient books. However, whether Guizhi Fuling Formula is really suitable for these diseases still needs further study for verification. The author systematically searched CNKI, Wanfang, SinoMed, PubMed, EMbase, Cochrane Library database: 2 304 papers on clinical research of Guizhi Fuling, covering 13 systems and 128 diseases. Combined with the questionnaire of experts, we investigated the knowledge of experts of traditional Chinese medicine, Western medicine and combination of Chinese and Western medicine on the applicable indications of Guizhi Fuling Formula in this paper, systematically elaborated the clinical applications of Guizhi Fuling Formula, and summarized the applicable indications of Guizhi Fuling Formula, in order to provide a reference for the clinical rational application of Guizhi Fuling Formula, and provide a reference also for clinical medication.

[Application of BeWo cell model in studies on placental transport mechanism].

As placenta barrier controls material exchanges between mother and fetus during pregnancy, studies on the placental transport mechanism of drugs is of great importance to analyze the efficacy, safety and toxicity of drugs. BeWo cells are derived from human choriocarcinomas, which can form monolayer trophoblast cells to offers an efficient placenta barrier in vitro for estimating nutrient and drug intake, efflux and transport. This essay focuses on the establishment and characteristics of BeWo cell model, and the advance on studies on nutrient and drug intake, efflux and transport mechanism by applying the model.

Chinese medicine improves postoperative quality of life in endometriosis patients: a randomized controlled trial.

OBJECTIVE: To investigate the effect of Chinese medicine (CM) and Western medicine (WM) on quality of life (QOL) after conservative surgery for endometriosis. METHODS: A total of 320 patients with endometriosis were randomized into two groups by using random block design, CM group (160 cases, activating blood circulation and removing blood stasis treatment based on syndrome differentiation) and WM group (160 cases, gonadotropin-releasing hormone agonist or gestrinone treatment) after conservative surgery. Treatment was given for 3-6 months (according to the revised American Fertility Society scoring system stage), and the World Health Organization QOL-BREF (WHOQOL-BREF) was applied to patients before and after treatment to assess QOL. RESULTS: There were 136 cases in the CM group and 141 cases in the WM group completing therapy. In the CM group, the use of the WHOQOL-BREF showed that the physical, psychological and environmental scores posttreatment were significantly higher than those at pre-treatment (P < 0.05), and for 12 items (pain and discomfort, energy and fatigue, sleep and rest, mobility, activities of daily living, work capacity, negative feelings, health and social care: accessibility and quality, participation in and opportunities for recreation/leisure activities, appetite, QOL score, overall health status and QOL), the difference in scores was significant (P < 0.05). In the WM group, 4 items (pain and discomfort, opportunities for acquiring new information and skills, QOL score, overall health status and QOL) had significantly different scores post-treatment compared with those at pre-treatment (P < 0.05). Before treatment, the QOL in the two groups of patients showed no significant difference (P > 0.05). After treatment, the scores for physical health in the CM group were significantly higher than those of the WM group (P < 0.05) and the scores of 4 items (mobility, activities of daily living, sexual activity, QOL score) in the CM group were significantly higher than those in the WM group (P < 0.05). CONCLUSIONS: CM and WM treatment could improve the QOL of patients with endometriosis after conservative surgery. CM treatment is more effective than WM.

Controlling the recurrence of pelvic endometriosis after a conservative operation: comparison between Chinese herbal medicine and western medicine.

OBJECTIVE: To compare the clinical effect of Chinese medicine (CM) and Western medicine (WM) for controlling the recurrence of pelvic endometriosis after a conservative operation. METHODS: The study was a multi-center, randomized, parallel controlled and prospective clinical trial. Patients were randomly divided into two groups: CM group (106 cases) and WM group (102 cases). Drugs were given to patients during 1-5 days of the first menstruation after a conservative operation in both groups. Patients with stages I and II (revised American Fertility Society) were treated for 3 months, while the patients with stages III and IV were treated for 6 months. The patients in the CM group were treated using three types of Chinese herbal medicine based on syndrome differentiation. Patients in the WM group were treated using gonadotropin releasing hormone agonist (GnRH-a) or gestrinone. Patients treated with GnRH-a received add-back therapy of Tibolone Tablets once a day after 4 months of treatment. Any cases of dysmenorrheal chronic pelvic pain, menstruation and any adverse reactions of patients were recorded once a month during the preoperative and postoperative periods and once every 3 months during the follow-up period. During the preoperative, postoperative and the follow-up periods, patients underwent type B ultrasonography of the pelvis and measurements of serum CA125 levels, gynecologic examination, routine evaluations of blood, urine, hepatic function (glutamate pyruvate transaminase), renal function (blood urea nitrogen) and electrocardiograms. During the follow-up period they underwent type B pelvic ultrasonography, measurement of serum CA125 levels and further gynecologic examinations. The two treatments were compared for clinical recurrence rates, pregnancy rates and the incidence of adverse reactions. RESULTS: The incidence and timing of recurrence of endometriosis were not significantly different between the two groups. The first pregnancy achieved by the patient in the CM group was significantly earlier than that in the WM group (P <0.05). Moreover, the incidence of adverse reactions in the WM group was significantly higher than in the CM group (P <0.01). CONCLUSIONS: Treatment with Chinese herbal medicines prevented the recurrence of endometriosis after a conservative operation, improved the conception rate and showed fewer and lighter adverse reactions than did treatment with WM therapy. Treatment with Chinese herbal medicine meets the need of patients wishing to have a child following endometriosis and is an appropriate form of clinical treatment.
