The effects of oxygen partial pressure on cryopreservation of the cells with organ preservation solution were explored. Hypoxic UW solution was made by purging the UW solution with argon. The pig proximal tubule epithelial cells (LLC-PK1 cells) were cryopreserved in hypoxic UW solution (Ar-UW group) or standard UW solution (UW group) at 4 degrees C for 48 h. Trypan blue staining and LDH detection were performed to evaluate the injury of the cells. The results showed that the oxygen partial pressure in Ar-UW group was significantly declined from 242+/-6 mmHg to 83+/-10 mmHg. After cryopreservation at 4 degrees C for 48 h, LDH leakage rate and Trypan blue-stained rate in Ar-UW group were (11.3+/-3.4)% and (10.5+/-4.7)%, respectively, which were significantly lower than in UW group [(49.5+/-6.9)% and (47.6+/-9.3)% respectively, both P<0.01]. It was concluded that lower oxygen partial pressure of UW solution was more beneficial to the cryopreservation of LLC.

In order to explore the method to prepare hypoxia UW solution and the stability and preservation of hypoxia UW solution, UW solution was purged by argon or air for 15 min or 60 at a flow rate of 0.8 or 2 L/min, and the oxygen partial pressure of UW solution was detected. The hypoxia UW solution was exposed to the air or sealed up to preserve by using different methods, and the changes of oxygen partial pressure was tested. The results showed that oxygen partial presure of 50 mL UW solution, purged by argon for 15 min at a flow rate of 2 L/min, was declined from 242+/-6 mmHg to 83+/-10 mmHg. After exposure to the air, oxygen partial pressure of hypoxia UW solution was gradually increased to 160+/-7 mmHg at 48 h. After sealed up by the centrifuge tube and plastic bad filled with argon, oxygen partial pressure of hypoxia UW solution was stable, about 88+/-13 mmHg at 72 h. It was concluded that oxygen of UW solution could be purged by argon efficiently. Sealed up by the centrifuge tube and plastic bag filled with argon, oxygen partial pressure of UW solution could be stabilized.

This paper analysed the rhinoscope's clinical value in microsurgical treatment of intracranial aneurysms. Application of the rhinoscope in 87 patients, only 2 patients had ruptured during operation. However, 11 cases had ruptured in 94 cases without using rhinoscope, P < 0.05, they had a significant difference. By DSA follow-up review, 82 cases of used rhinoscope only 2 cases had remained the aneurysm neck, but 9 cases had the aneurysm neck in 77 cases which had not used the rhinoscope in the microsurgical treatment, P < 0.05, they also had significant difference. The application of rhinoscope in microsurgical treatment of intracranial aneurysms intraoperative, can reduce the risk of the intraoperative aneurysm rupture. It can achieve better clinical effect.

Background: Tumor markers are widely used in clinical practice and have become important indicators in assessing cancer progress. There is increasing concern that chemotherapy combined with traditional Chinese medicine has effects in decreasing the level of tumor markers. Objective: To investigate the effects of chemotherapy combined with Kangliu Zengxiao Decoction (KLZX), a compound Chinese herbal drug, on tumor markers carbohydrate antigen 50 (CA 50), cytokeratin 19 fragment (CYFRA21-1) and carcinoembryonic antigen (CEA) in patients with advanced non-small-cell lung cancer (NSCLC) and to explore the relationships between clinical efficacy and tumor markers. Design, setting, participants and interventions: Patients were included from Punan Hospital of Shanghai Pudong New District and Longhua Hospital between October 2008 and December 2009. Seventy-four subjects with advanced NSCLC were randomly assigned into treatment group (n=37) and control group (n=37). Patients in the control group were treated with chemotherapy alone while patients in the treatment group were treated with chemotherapy combined with KLZX. Chemotherapy of NP (vinorelbine + cisplatin) was given for two cycles and patients in the treatment group were administered with KLZX during chemotherapy. Main outcome measures: Levels of CA50, CYFRA21-1 and CEA before and after treatment were evaluated and the relationship between changes in levels of tumor makers and tumor size, clinical symptoms and living condition score (Karnofsky score) was analyzed. Results: No patients achieved a complete remission. The disease control rates (complete remission (CR)+partial remission (PR)+no change (NC)) were 89.20% (33/37) and 70.30% (26/37) in the treatment and control group respectively (P<0.05). The levels of CA50, CYFRA21-1 and CEA were clearly decreased in the treatment group after treatment (P<0.05) while also decreased in the patients without progression of disease. There were no obvious changes of CA50, CYFRA21-1 and CEA in the control group, and there was even a trend of increase. Furthermore, the improvement rates of clinical syndrome were 51% (19/37) vs 11% (4/37) (P<0.05) in the treatment group and control group respectively. The total response rates of quality of life were 91.89% (34/37) vs 56.76% (21/37) (P<0.01) in the treatment and control group respectively. Conclusion: Combined chemotherapy with KLZX in treating advanced NSCLC can acquire better stabilizing tumor foci, decrease levels of tumor markers and improve the clinical symptoms and Karnofsky score.

Objective To research the protective effects of totalPanax Japonicus extract on learning memory, antioxidation, and anti-apoptosis of aging mice,and explore the mechanism. Methods Male mice were randomly divided into normal group, model group, Vitamin E (VE) group, Panax Japonicus extract low and high dose group. Except for the normal group, the other groups were injected withD-gal on the back of the neck subcutaneously to establish aging model. Normal group and model group were given a gavage with saline and each treatment group was given a gavage with totalPanax Japonicus extract and VE once a day for 7 weeks after the aging model established. All mice were be measured their learning and memory ability in the eighth week. After the test, the morphological changes of CA1 neurons were observed by HE stain. SOD, GSH-Px, MDA levels in brain tissue were measured by biochemical method, the expressions of Bcl-2 and Bax mRNA were evaluated by RT-PCR.Results Mice inPanax Japonicus extract low and high dose group could spend less time in searching for the platform, improve the learning and memory ability. TotalPanax Japonicus extract increased the activity of SOD and GSH-Px, while decreased the content of MDA. In addition, it could increase the expression level of Bcl-2 mRNA and reduce the expression level of Bax mRNA as well.Conclusion TotalPanax Japonicus extract has anti-aging effect.
