The effect of astaxanthin on N(Ω)-nitro-L-arginine methyl ester (L-NAME) induced preeclampsia disease rats was investigated. Thirty pregnant Spraque-Dawley rats were randomly divided into three groups (n = 10): blank group, L-NAME group and astaxanthin group. From day 5 to 20, astaxanthin group rats were treated with astaxanthin (25 mg x kg(-1) x d(-1) x bw(-1)) from pregnancy (day 5). To establish the preeclamptic rat model, L-NAME group and astaxanthin group rats were injected with L-NAME (125 mg x kg(-1) x d(-1) x bw(-1)) from days 10-20 of pregnancy. The blood pressure and urine protein were recorded. Serum of each group was collected and malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide synthase (NOS) activities were analyzed. Pathological changes were observed with HE stain. The expression of NF-κB (nuclear factor kappa B), ROCK II (Rho-associated protein kinase II), HO-1 (heme oxygenase-1) and Caspase 3 were analyzed with immunohistochemistry. L-NAME induced typical preeclampsia symptoms, such as the increased blood pressure, urinary protein, the content of MDA, etc. Astaxanthin significantly reduced the blood pressure (P < 0.01), the content of MDA (P < 0.05), and increased the activity of SOD (P < 0.05) of preeclampsia rats. The urinary protein, NO, and NOS were also decreased. HE stain revealed that after treated with astaxanthin, the thickness of basilal membrane was improved and the content of trophoblast cells and spiral arteries was reduced. Immunohistochemistry results revealed that the expressions of NF-κB, ROCK II and Caspase 3 in placenta tissue were effectively decreased, and HO-1 was increased. Results indicated that astaxanthin can improve the preeclampsia symptoms by effectively reducing the oxidative stress and inflammatory damages of preeclampsia. It revealed that astaxanthin may be benefit for prevention and treatment of preeclampsia disease.

Background and purpose: The effects of tumor after radiotherapy and chemotherapy with tumor cell apoptosis have positive correlation. Survivin is an apoptosis suppressor gene, which is overexpressed in lung cancer. The reduction of its expression can increase lung cancer cell apoptosis. RNA interference can speciifcally and effectively blocked the expression of this gene. After accepting a dose of radiation, tumor tissues can raise the rate of gene transduction. The purpose of this study was to investigate the effects of the expression of Survivin gene suppressed by intratumor injection siRNA and radiation in lung cancer. Methods:Mouse subcutaneous transplanted with tumors were randomly divided into four groups:untreated group (group A), group with intratumor injection siRNA (group B), group with radiation (group C), group 4 Gy pre-irradiation combination with intratumor injection siRNA (group D). Two days later, mouse with different treatments were executed by cervical dislocation and stripped the subcutaneous tumors. mRNA and protein levels of Survivin gene were detected by quantitative real-time PCR (qRT-PCR) and Western blot; Cell cycle and cell apoptosis were assayed by lfow cytometry (FCM). Results:The expression of Survivin gene in mRNA and protein levels in group B, C, and D were signiifcantly reduced compared with group A. The differences of Survivin expression in mRNA level between group A and group D were statistically signiifcant. Compared with the other 3 groups, the expression of Survivin gene in group D was signiifcantly reduced, the differences were statistically signiifcant (P=0.036);The proportion of cells in S-phase of group D was (2.70±0.34)%, compared with group B [(8.93±0.75)%] and group C [(6.71±0.51)%], that was significantly reduced. The differences of the proportion of S-phase cells in group A and group D were statistically signiifcant (P=0.034);The rate of cell apoptosis in group D was (25.67 ± 0.65)%, which was signiifcantly increased compared with the rate of cell apoptosis in the other 3 groups, the differences were statistically signiifcant (F=78.82, P<0.05). Conclusion:Pre-irradiation can enhance the transduction rate of siRNA, reduce the expression of Survivin gene in lung cancer, promote cell apoptosis, and increase the sensitivity of the radiotherapy.

The modernization of Traditional Chinese Medicine (TCM) is urgent need of the modern theory of TCM, is a consensus. But, How to establish and what kind of modern TCM theory, is far from a consensus. Based on the summarization of the common law in the construction of scientific theory, we are trying to give a answer that are expected to form a consensus. Firstly, we have illustrated the trend that the development of TCM theory should learn from the life and medical sciences theory function and value; Secondly, we have proven that TCM and TCM theory belongs to the traditional medicine and theory and pointed out the limitation of the traditional medicine, TCM and its theory. And then we have revealed the inevitable trend of traditional medicine, TCM and its theory development at home and abroad, logically obtained the inevitable choice of constructing the modern TCM basic theory; Lastly, we have analyzed the different discipline new theory construction process and method at home and abroad and discovered the common five steps rule, put forward three principles and five steps of constructing modern TCM basic theory, demonstrated its important role during the theoretical revolution promoting Chinese Medicine theory from phenomenon description to mechanism clarification and the scientific value of Chinese Medicine theory in the domestic and foreign development trend.

Objective To retrospectively analyze the treatment outcomes and failure patterns in patients with head?and?neck cancer of unknown primary head?and?neck cancer of unknown primary, and to compare the efficacy between elective mucosal irradiation and ipsilateral neck treatment. Methods The clinical data of patients with head?and?neck cancer of unknown primary who were admitted from January 2007 to December 2013 were retrospectively collected. Thirty?one patients received elective pharyngeal mucosal irradiation and 61 patients only received ipsilateral neck treatment. The SPSS 19. 0 software was used for comparison of the survival and local control between the two groups. Results In the 92 patients, the median age was 57 years;79. 3% had metastasis to level Ⅱ lymph nodes;the median follow?up time was 36. 5 months;the 3?year overall survival, mucosal control, and neck control rates were 89. 0%, 86. 6%, and 82. 4%, respectively. Primary sites were found in 15 patients, containing nasopharynx in 4 patients, oropharynx in 3 patients, oral cavity in 3 patients, throat and hypopharyngeal part in 3 patients, maxillary sinus in 1 patient, and esophagus in 1 patient. The patients undergoing elective pharyngeal mucosal irradiation had significantly higher 3?year mucosal control and neck control rates than those undergoing ipsilateral neck treatment ( 100% vs. 74. 9%, P= 0. 040;87. 5% vs. 62. 2%, P= 0. 037 ) . There was no difference in the 3?year overall survival rate between the two groups ( 83. 5% vs. 88. 7%, P= 0. 910 ) . Conclusions For patients with head?and?neck cancer of unknown primary, elective pharyngeal mucosal irradiation can reduce the incidence of primary site and increase the neck control rate. A new standard for target volume delineation should be established as soon as possible for elective prophylactic pharyngeal mucosal irradiation.
