A high-throughput three-dimensional (3D) hepatocyte culture model is constructed in this study. It is capable of replicating the 3D in vivo environment and offers the advantages of high throughput, enhanced reproducibility, low cost, and simplified operation, rendering a valuable tool for hepatotoxicity screening of traditional Chinese medicine (TCM). First, we constructed the 3D high throughput liver chip model using collagen hydrogel. The precision and its difference with traditional cell culture plates were assessed using acetaminophen, Tripterygium hypoglaucum, and Qili San as the references. The feasibility of this model was also investigated by comparing the hepatotoxicity among four batches of T. hypoglaucum and Qili San. The methodology verification shows that the 3D hepatocyte model is better than traditional two-dimensional (2D) cell culture model in precision and feasibility. Subsequently, we compared the hepatotoxicity of different samples over a period of three or seven days and found that the hepatotoxicity of TCM extracts increased over time. Finally, we compared the hepatotoxicity of T. hypoglaucum and its compound formula Kunxian capsule under equivalent concentration. The results showed that the compound Kunxian capsule could significantly reduce hepatotoxicity of T. hypoglaucum. Generally, we constructed a high-throughput, robust 3D liver-on-a-chip model with the potential of rapid assessing TCM-induced liver toxicity.

Background Glaucoma is one of the leading causes of blindness worldwide;while the different types of glaucoma is vary from different region. Objective Present study was to survey the prevalence and types of glaucoma among peasants of Uigur adults in Kuche county and offer the basis for the prevent and treatment of glaucoma in Uigur nationanlity. Methods 4191 Uigur peasants aged 40 years or above were collected in Kuche county for the survey of prevalence and types of glaucoma by randomized cluster sampling in March and April of 2009. The subjects were grouped into 40-,50-,60- and ≥70 years groups according to the distribution of age. The disease history of glaucoma, regular eye examination, funds examination and measurement of the anterior chamber depth, gonioscope were performed in the all subjects. Darkroom prone test and mydriasis test were carried out in suspicious glaucomous patients. The depth of periphery anterior chamber was assessed based on van Herick' s criteria, and the width of chamber angle was graded based on Scheie' s method. The standardized training was performed. This survey approved by Xinjiang Medical Ethics Committee, all subjects signed the informed consent before the examination. Results 4191 of 4873 subjects finished all the examinations with the response rate 86%. All the subjects showed a good compliance. The prevalence of glaucoma was 3. 79% , and the prevalence of primary angle-closed glaucoma(PACG) .primary angle-open glaucoma (PAOG) and secondary glaucoma was 2.22% ,0.26% and 1. 31% respectively, showing a significant difference among the different types of glaucoma( P<0. 05). The prevalence of glaucoma was elevated with aging (χ2 - 116. 69 ,P<0. 05) and presented a high rate in male subjects compared with female ones(χ2 = 7. 34, P<0. 05 ). Bilateral blindness was found in 19.75% glaucoma peasants, in which 25.3% glaucoma peasants received anti-glaucoma surgery. The distribution of visual acuity of patients was of significant difference among different age groups(χ2 = 37. 69 ,P<0. 05 ) . Conclusions The prevalence of the glaucoma among Uigur peasants in Kuche county was higher than most area no matter inland or overseas. PACG still is the common type in those people.

OBJECTIVETo investigate the impact of treatment modality and clinicopathologic profile on prognosis in primary fallopian tube carcinoma.

METHODSThe data of 64 cases with primary fallopian tube carcinoma treated between January 1991 and June 2006 were analyzed. The clinicopathological data were retrospectively analyzed.

RESULTSThe overall 5-year survival rate of this series was 56.3%. The overall 3- and 5-year survival rate was 84.6% and 65.4% in surgical staging group versus 58.3% and 33.3% in no surgical staging group with a significant difference between two groups (P = 0.0429; P = 0.043), which was 89.5% and 68.4% in optimal cytoreduction group versus 66.7% and 41.7% in suboptimal cytoreduction group (P = 0.0466; P = 0.0444). However, there was no significant difference in 3-year and 5-year survival rate between the group with pelvic lymphadenectomy and the group without (84.2% vs. 69.2%, P = 0.4667; 63.1% vs. 53.8%, P = 0.459), and also between the group treated using CAP/CP regimen and the group by TP regimen for chemotherapy (81.8% vs. 80.0%, P = 0.8946; 59.1% vs. 60.0% P = 0.9582). It was found that the 5-year survival was correlated with FIGO stage (III-IV vs. I - II, P = 0.0197), differentiation grade (G3 vs. G1 + G2, P = 0.003), pathologic type (other type vs. serous, P = 0.0494), lymph nodes status (positive vs. negative, P = 0.0295).

CONCLUSIONSurgical staging, optimal cytoreduction, differentiation grade, pathologic type, lymph node status are important factors influencing the 5-year survival in primary fallopian tube carcinoma. Pelvic lymphadenectomy is necessary and feasible to perform during the procedure of surgical staging and cytoreduction. CAP/CP and TP regiment are similarly effective in adjuvant chemotherapy for primary fallopian tube carcinoma.
