Objective To evaluate the changes of thyroid function during pregnancy in the second and third trimester in the regions with or without iodine deficiency. Methods The serum TSH, FT 3, FT 4 and TT 4 levels of 90 pregnant women (30 from iodine deficient area as study group, 60 from iodine sufficient area as control group) and 30 non pregnant women were assayed by high sensitive immunoradiometric assay (IRMA) or radioimmunoassay (RIA), and urine iodine level of pregnant women before delivery was also examined. Results (1) The serum TSH level in pregnant women in the second and third trimester was significantly higher than that of non pregnant women. The serum free thyroid hormone levels of pregnant women were significantly lower than that of non pregnant women, especially in the third trimester. (2) The serum TSH level of pregnant women from iodine deficient area in the second trimester and before delivery was significantly higher than that of pregnant women from iodine sufficient area (P

Objective To identify clinicopathologic characteristics and prognostic factors through a retrospective analysis of 404 colon cancer patients.Methods A total of 404 patients(209 of them were followed up with inquisition) with colon cancer were surgically treated from 1993 to 2003 and studied by univariate and multivariate analysis.Results Using univariate analysis age of patients,it was found that differentiation degree of the tumors,lymphatic invasion,abdominal and distant metastases,TNM stage and adjuvant radiotherapy were associated with outcome.(2)Multivariate analysis showed that only abdominal and distant metastases and TNM stage were associated with prognosis.Conclusion Multivariate analysis proved following list are independent prognostic factors: abdominal,distant metastases and TNM stage.

To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.

A laboratory animal expert consultation system provides an interactive platform for industry experts and users. Based on intelligent mobile terminal used as the application supporter, the platform combines the internet with laboratory animal to share the experts' knowledge, breaks through temporal and spatial restrictions, and resolves other problems such as poor timeliness of inquire service, knowledge data staticization, and irrational exploitation of internet to gain prompt inquire service. The platform would meet the needs of industry users for real-time aids and bridge the gap between industry experts and users. Thus, the transfer of expert' knowledge is realized in pace with the increasing knowledge resource of this platform to accelerate the transformation of theoretical knowledge into the industry. Our study focuses on the system characteristics, the main frame structure, the design of function module and the system implementation.

Objective:To investigate the effects of anemoside B4 on proliferation, apoptosis and migration of ovarian cancer SKOV3 cells through a variety of biological methods, and further to explore its mechanism.Methods:Ovarian cancer SKOV3 cells were cultured in vitro. CCK-8 method was used to detect the proliferation of SKOV3 cells treated with different concentrations of anemoside B4, and IC50 value was calculated. Flow cytometry was employed to detect the apoptosis of cells treated with IC50 concentration of anemoside B4 for different time length; Transwell method was used to detect the migration and invasion of cells treated with IC50 concentration of anemoside B4 for different time length. Western blot was used to detect changes in the expression of related proteins.Results:Anemoside B4 can effectively inhibit the proliferation of SKOV3 cells, showing a concentration-dependent IC50 value of 6.08±0.56 μM, and the inhibitory effect is stronger than the positive control drug cisplatin, with statistically significant difference (P<0.05) . Flow cytometry showed that anemoside B4 could induce SKOV3 cells apoptosis, reduce Bcl-xl expression, and up-regulate the expression of Bax, cleaved-caspase-3 and PARP. Compared with the group of 0 h, the difference was statistically significant (P<0.05) . Crocetin could down-regulate the expression of N-cadherin and up-regulate the expression of E-cadherin, thereby inhibiting the migration of SKOV3 cells. Anemoside B4 could inhibit the expression of JAK/STAT3 signaling pathway proteins.Conclusion:Anemoside B4 can effectively inhibit the proliferation of cervical cancer cells, and induce SKOV3 cell apoptosis by regulating the JAK/STAT3 signaling pathway to inhibit their migration. Crocetin has great potential in the research and development of ovarian cancer therapy.

Objective To verify the safety and efficacy of IONTRIS particle therapy system ( IONTRIS) in clinical implementation. Methods Between 6.2014 and 8.2014, a total of 35 patients were enrolled into this trial:31 males and 4 females with a median age of 69 yrs ( range 39?80) . Ten patients had locally recurrent head and neck tumors after surgery, 4 cases with thoracic malignancies, 1 case with hepatocellular carcinoma, 1 case with retroperitoneal sarcoma, and 19 cases with non?metastatic prostate carcinomas. Phantom dose verification was mandatory for each field before the start of radiation. Results Twenty?two patients received carbon ion and 13 had proton irradiation. With a median follow?up time of 1 year, all patients were alive. Among the 16 patients with head and neck, thoracic, and abdominal/pelvic tumors, 2, 1, 12, and 1 cases developed complete response, partial response, stable disease, or disease progression, respectively. Progression?free survival rate was 93.8％ (15/16). Among the 19 patients with prostate cancer, biological?recurrence free survival was 100％. Particle therapy was well tolerated in all 35 patients. Twenty?five patients (71.4％) experienced 33 grade 1 acute adverse effects, which subsided at 1 year follow?up. Six ( 17.1％) patients developed grade 1 late adverse effects. No significant change in ECOG or body weight was observed. Conclusions IONTRIS is safe and effective for clinical use. However, long term follow?up is needed to observe the late toxicity and long term result.
