The aim of this study is to investigate the protection effect of tanshinone IIA (Tan) against triptolide (TP)-induced liver injury and the mechanisms involved. Acute liver injury was induced by intraperitoneal injection of TP (1 mg x kg(-1)) in mice. The activities of AST, ALT and LDH in serum and the levels of GSH, GST, GSH-PX, SOD, CAT and MDA in liver tissue were detected. The histopathological changes of liver tissues were observed after HE staining. Nrf2 translocation in liver tissue was detected by Western blotting, and real-time PCR was used to measure the expression levels of GCLC, NQO1 and HO-1 mRNA. The results showed that pretreatment with Tan significantly prevented the TP induced liver injury as indicated by reducing the activities of AST, ALT and LDH (P < 0.01). Tan pretreatment also prevented TP-induced oxidative stress in the mice liver by inhibiting MDA and restoring the levels of GSH, GST, SOD and CAT (P < 0.05). Parallel to these changes, pretreatment with Tan could attenuate histopathologic changes induced by TP. Furthermore, the results indicated that Tan pretreatment caused nuclear accumulation of Nrf2 as well as induction of mRNA expression of antioxidant response element (ARE)-driven genes such as GCLC, NQO1 and HO-1. These results indicated that Tan could protect against TP-induced acute liver injury via the activation of Nrf2/ARE pathway.

Objective To study a scoring method for assessing function status of cardiovascular system quantitatively. Methods First, exercise heart rate variability (EHRV) was obtained from the primary dynamic electrocardiogram (ECG) recorded during exercise testing. Then appropriate entropy, relative complexity, and other three parameters extracted from poincare dispersed-dot plot were extracted from the EHRV. Discriminant analysis was used to classify two extreme groups.Results Based on the values of two groups from the discriminant formula, a scoring formula was proposed and four ranks were divided according to different score domains. A novel scoring method was established. To validate the proposed scoring method, 60 middle-aged hypertensives, 50 elder subjects and 110 young healthy subjects were examined and scored. Conclusion Scores of 220 subjects are consistent with their real health status. The proposed scoring method reflects the status of the subject's cardiovascular system effectively.

BACKGROUND: Autologous bone, bone substitute materials and guided bone regeneration (GBR) technique can repair jaw defects, but the absorption speed of bone substitute materials and GBR membrane are faster than the formation speed of new bone, therefore, it affects the volume and shape of new bone.OBJECTIVE: To investigate the role of personalized prefabricated titanium template, autologous bone and nano-hydroxyapatite on restoration of maxillary defect in rabbit.METHODS: A total of 18 rabbits were randomly divided into two groups, and maxillary alveolar defect with 10 mm length and 5 mm high was created. The template was implanted in both two groups, and fastened with titanium screws. Autologous and nano-hydroxyapatite were placed into the defect in experimental group; neither autologous bone nor bone substitute materials were implanted into the defect in control group. New bone formation, X-ray findings, and histological changes with HE stain were carded out 4, 8 and 12 weeks postoperatively.RESULTS AND CONCLUSION: The quality of new bone in experimental group was batter than that in control group 4 weeks postoperatively, but the quality of new bone was almost the same 8 and 12 weeks postoperatively. By paired t-test, there was significant difference in new bone density between the experimental group and the control group 4 .weeks after operation (P<0.01), but there was no significant difference in new bone density between the experimental group and the control group 8 and 12 weeks after operation (P > 0.05). Autologous bone and nano-hydroxyapatite can restore the defect of maxillary alveola.Personalized prefabricated titanium template can play an important role of screen membrane and external scaffold in new bone formation, and remain shape of new bone.

This study is to investigate the protection effect of schisandrin B (Sch B) against oxidation stress of HK-2 cells induced by cisplatin and the mechanisms involved. HK-2 cells were cultured and divided into different groups: solvent control group, cisplatin exposure group, positive group, Sch B treatment group. Cell viability and toxicity were evaluated by MTT and LDH assay. GSH level and SOD enzymes activities were also measured. DCFH-DA as fluorescence probe was used to detect ROS level by fluorescence microplate reader. Nrf2 translocation was detected by Western blotting. Real time Q-PCR was used to detect expressions of NQO1, HO-1 and GCLC mRNA level. The results showed that Sch B could significantly inhibit the decline of cell viability induced by cisplatin treatment (P < 0.05) and the protective effect was in a dose dependent manner. Furthermore, Sch B treatment significantly inhibited the increase of ROS level induced by cisplatin and reversed the decrease of GSH level (P < 0.05). When Sch B concentration was up to 5 micromol x L(-1), SOD enzyme activities were also enhanced significantly compared with that of the cisplatin group (P < 0.05). It was shown that Sch B could cause nuclear accumulation of Nrf2 in association with downstream activation of Nrf2 mediated oxidative response genes such as GCLC, NQO1 and HO-1. These results suggested Sch B could protect against the oxidative damage of HK-2 cells induced by cisplatin via the activation of Nrf2/ARE signal pathway.

[Objective] Expressions of human epidermal growth factor receptor 2(HER-2),p53,estrogen receptor (ER),and progesterone receptor (PR) in tissues of breast invasive ductal carcinoma are not only applied to determine the therapeutic regimen,but they may also be related to the prognosis.We investigated the levels of these proteins among different clinical stages and the correlations.[Method] One hundred and thirty-eight tissues from cases with breast invasive ductal carcinoma were tested with immunohistochemistry.New scoring standards and rank test were applied.The indices were digitalized and semi-quantified.[Results] In the tissues from high clinical stage,the expression of HER2 was significantly increased,while expression of PR was markedly decreased.[Conclusion] Expression of HER2 and PR might be better markers for predicting clinical stages and prognosis.
