Objective To probe into the kinetics of gallstone formation.Methods Fifty seven rabbits were divided into five groups: (1) normal control with standard fodder, (2)1 2% cholesterol was added into the fodder,(3)1 2% cholesterol plus indomethacin in the fodder,(4)1 2% cholesterol plus erythromycin,(5) 1 2% cholesterol plus Dong Li San, a Chinese herb compound. All animals were feed four weeks before measurement.Results Gallstone developed in 0 out of 13 in group 1, in 12 out of 14 rabbits in group 2, in 4 out of 10 rabbits in group 3, in 0 out of 10 in group 4, and in 2 out of 10 in group 5. Compared with that in group 1 rabbits in group 2 had higher level of cholesterol and mucin in bile,much higher common bile duct pressure and cystic duct resistance,much lower gallbladder emptying rate ( P

Bile collected from 28 cases with various hepatic or biliary diseases during operation was assayed for the ?-glucuronidase level. In Group I consisting of 14 patients with primary intrahepatic stone, the ?-glucuronidase level averaged 2250.67 u/dl, while in Group II consisting of 14 patieats with other hepatic diseases, it averaged only 463.99 u/dl(P = 0.01).The patients of both groups showed a declination of the enzyme level gostoperatively, but in Group I, the enzyme level raised with other hepatic diseases, he T-tube. The AMPS and MP contents of the bile .remarkable inhibitory effect on two substances exert their function in positive remarkable inhibitory effect on at pH4,6. It is believed that. ?-glucuronidase, Group 11 consisting the results of thisles in the reformation of biliary stones reformation biliaryWhen ?-glucuronidase level is lower than 200u/dl.Chinese traditional prescriptions with glycynrhizae liquid extract shows a remarkable inhibitory effect on this enzyme. In Chinese traditonal prescriptions, the drugs which can promote circulation and clear deposit are usually added. According to the results of this study, the authors suggest that the therapeutic effect of glycyrrhizae be emphasized.

OBJECTIVE: To analyze the relationship between chronic pain and painprone meutal disorders and investigate the effect of psychological intervention and medication.DATA SOURCES: Related literatures about the relationship between chronic pain and pain-prone mental disorders were searched on computer in Medline and Embase from January 1989 to May 2004 with the retrieval word of "Chronic pain, emotional disorder, treatment", the language was limited to English. The subjects were patients who suffered from chronic pain for above 6 months.STUDY SELECTION: Related literatures about the relationship between chronic pain and pain-prone mental disorders and its therapeutic interventions were carried on primary trial to delete those obsolete and repetitive literatures, and the others were used to search in the full text. The quality was appraised mainly on the basis of the data authenticity, preciseness of the designation, strictness of the implementation and reasonability of the statistical analysis.DATA EXTRACTION: Altogether 20 literatures were obtained and 11literatures were proved accordant with the inclusion standard. 9 literatures were excluded because 7 were repetitive experiments and two were Meta analyses.DATA SYNTHESIS: 11 literatures include experimental group and control group, patients in the experimental group were treated with analgetic combined with psychological intervention and antidepressant while those in the control group were only given analgetic; the outcomes of the two groups were compared.CONCLUSION: Chronic pain may co-exist with emotional disorders. It can be remarkably alleviated by the administration of analgetic combined with psychological intervention and antidepressant, which proves better than single analgetic medication.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation, endangering human health and life. Currently, there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix, generating vascular factors, affecting epithelial-mesenchymal transformation, or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance (MDR) are the regulation of membrane proteins, apoptosis-regulated gene expression, enzyme-mediated multidrug resistance, DNA damage repair, and epithelial-stromal transformation, resulting in ineffective treatment of tumors. Therefore, the search for natural, safe, and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment, researchers have conducted more extensive studies on its monomers and compounds. In addition, the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion, metastasis, and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore, they can also improve the tolerance of patients to chemotherapy drugs, relieve side effects of chemotherapy, reduce the chance of recurrence, and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis, reversing drug resistance, prolonging the prognosis of cancer patients, improving their quality of life, and prolonging their survival time. Currently, various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis, and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion, anti-metastasis, and anti-tumor resistance therapy in recent years, in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.

This study was performed to evaluate the oncological and reproductive outcomes of childbearing-age women treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred and forty eight non-epithelial ovarian tumor women treated with FSS between January 1, 2000 and August 31, 2015 from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overall survival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P = 0.023), whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associated with PFS and OS (P < 0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), none developed amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestations including 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis after FSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followed by ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase the PFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
