To our knowledge, there has been no clinical report of artesunate in the treatment of lung cancer. This study was designed to compare the efficacy and toxicity of artesunate combined with NP (a chemotherapy regimen of vinorelbine and cisplatin) and NP alone in the treatment of advanced non-small cell lung cancer (NSCLC).

Objective To investigate the effects of Xuebijing injection on the transcription factors GATA-3 and T-bet of rats after cardiopulmonary resuscitation (CPR). Method The rat models of CPR was made by using asphyxia method. Thirty SD rats were randomly (random number) divided into three groups at random: sham operation rats (B group), conventional CPR rats (C group) and Xuebijing (4 mL/kg) treated rats (D group). The levels of serum IL-12, IL-4, TNF-α and IFN-γ were measured by using ELISA. The expressions of T-bet and GATA-3 mRNA in serum were detected by RT-PCR. The analysis of variance was used to compare the means of different groups including t-test and Wilcoxon test. Results Compared with group B, the levels of serum IL-12, TNF-α and IFN-γ in group C and group D were significantly elevated after CPR for 6 hours (P<0.01). In group C, the expression of GATA-3 mRNA and GATA-3/T-bet decreased (both P < 0.05), while the expression of T-bet mRNA increased (P<0.01) after CPR for 6 hours. In group D, the expressions of GATA-3 mRNA and T-bet mRNA as well as GATA-3/T-bet increased after CPR for 6 hours. The levels of IL-12, IFN-γ and TNF-α in group D were lower than those in groupC (P<0.01). Compared with group C, the expression of GATA-3 mRNA and GATA-3/T-bet were significantly elevated and the expression of T-bet mRNA decreased in group D. ConclusionsThe transcription factors GATA-3 and T-bet may fail to get balance after CPR. The Xiebijing injectio can modulate the balance between GATA-3 and T-bet, and the levels of IL-12,IFN-γ and TNF-α.

Aim To observe the production of anti-idiotypic antibodies directed against AK auto Ab in the rabbit sera after long-term, high dose allogenic AK auto Ab injection. Methods Allogenic AK auto Ab (5mg/kg)was injected intramuscularly to rabbit once every other day for 90 days. Anti-idiotypic antibodies in rabbit sera were detected by ELISA. Results Rabbits injected with AK auto Ab generated anti-idiotypic antibodies that could react to F(ab′ )2 of AK auto Ab. The titers of anti-idiotypic antibodies reached the highest levels at 4 weeks after the administration of AK auto Ab and then gradually decreased. Conclusion Rabbits could be induced to form immune tolerance when high-does allogenic AK auto Ab is administrated for long-term.

The role of arginine vasopressin ( AVP) played in proliferation and differentiation of mouse primary osteoblast and its mechanism was investigated. 100 nmol/ L AVP was added into the medium containing primary mouse osteoblast: (1) After being cultured for 72 h, the proliferation of the cells was counted with a cell counter. (2) The media of cultured cells on 2,4,6,8,10 days were harvested and tested for the secreted ALP concentration by osteoblasts, and the cells were lysed in order to test the ALP concentration in cytosol. (3) The alizarin red staining was employed to detect the effect of AVP on calcium nodules formation on 8 th and 20 th days. (4) The osteoblast cells were incubated with AVP for 20 min, and then were lysed. Radioimmune assay was applied to test the change of cAMP in cytosol. These results showed that, compared to negative group, 100 nmol/ L AVP significantly promoted the proliferation of primary mouse osteoblast ( P<0. 01). ALP secretion was increased remarkably ( P <0. 01), and the number and area of calcium nodules were increased considerably(P<0. 01). The intracellular cAMP was increased after incubating cells with AVP for 20min ( P<0. 01). These results suggest that AVP may promote proliferation and differentiation of mouse primary osteoblasts by cAMP signal pathway.

OBJECTIVE: To report the prospective efficacy of 45 patients intracranial germinoma treated by radiotherapy and discuss its treatment. METHODS: From February 1998 to October 2007, a total of 45 intracranial germinoma patients were performed radiotherapy, including 15 combined chemotherapy in the Department of Oncology. Of them 23 were pathologically diagnosed while 22 cases were clinical diagnosed. Life table method showed the 5-year and 10-year survival rate. RESULTS: Forty patients were followed-up. Most symptoms of the patients were significantly reduced or disappeared completely. The 5-year and 10-year survival rate of all patients were 84% and 74%. CONCLUSION Radiotherapy is the main treatment for intracranial germinoma. Craniospinal irradiation, whole brain irradiation and partial brain irradiation are the main treatments. Radiotherapy combined with chemotherapy, which can reduce the radiation range and dose will be the trend.

Objective:To investigate the effect of ginkgo biloba extract (GBE) on oxidative stress in medial prefrontal cortex and excitatory/inhibitory balance of pyramidal neurons in chronic unpredictable mild stress (CUMS)-induced depressive model mice.Methods:Totally 48 SPF grade 7-week-old male C57BL/6J mice were divided into 4 groups according to random number table method: control+ saline group (CTRL+ Veh), control+ GBE group (CTRL+ GBE), model+ saline group (CUMS+ Veh), model+ GBE group (CUMS+ GBE), with 12 mice in each group.Mice in CUMS+ Veh group and CUMS+ GBE group were established by CUMS method, and mice in CTRL+ GBE group and CUMS+ GBE group were intraperitoneally injected with GBE (70 mg/kg) once a day, and mice in CTRL+ Veh group and CUMS+ Veh group were injected intraperitoneally with 0.9% sodium chloride solution.Then, the sucrose preference test, forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and open field test (OFT) was performed to evaluate the autonomous locomotion and exploration ability and anxiety-like behavior.The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in mPFC were determined by ELISA.Spontaneous excitatory postsynaptic currents (sEPSC) and spontaneous inhibitory postsynaptic currents (sIPSC) were detected by whole-cell recording.SPSS 23.0 was used for data analysis and two-factor analysis of variance(whether to get GBE, whether to mold, show as GBE×CUMS) was used for statistical analysis.Results:(1) Behavioral results: the the time spent in center and total distance of OFT and sugar preference rate of the four groups of mice were compared, and the interaction of GBE×CUMS was significant( F=24.90, 4.82, 3.91, all P<0.05). The results of simple effect analysis showed that the time spent in center ((47.15±3.58) s), the total distance((19.33±0.86) m) and the sugar preference rate((59.11±8.79)%) of the mice in CUMS+ Veh group were lower than those in the CTRL+ Veh group((61.55±2.49) s, (23.24±1.21) m, (84.02±7.45) %) (all P<0.01), and the above indexes in CUMS+ GBE group ((56.51±3.53) s, (20.75±1.31) m, (70.80±11.79)%) were higher than those in CUMS+ Veh group (all P<0.05). In the immobility time of FST and TST of mice in the 4 groups, the interaction of GBE×CUMS were significant( F=85.53, 83.39, both P<0.01). The immobility time of FST and TST in CUMS+ Veh group were higher than those in CTRL+ Veh group (both P<0.01 ), and the above indexes in CUMS+ GBE group were lower than CUMS+ Veh group(both P<0.05). (2)The results of ELISA showed that the interaction of GBE×CUMS of SOD level of mice in the 4 groups was not significant ( F=3.52, P=0.07), but the main effects of GBE factor and CUMS factor were both significant ( F=4.69, 46.93, both P<0.05). The interaction of GBE×CUMS of MDA level was significant( F=16.61, P<0.01). The level of SOD in the CUMS+ Veh group was lower than that in the CTRL+ Veh group ( P<0.01), and the level of SOD in the CUMS+ GBE group was higher than that in the CUMS+ Veh group ( P<0.05). The level of MDA in the CUMS+ Veh group was higher than that of the CTRL+ Veh group ( P<0.01), and the level of MDA in CUMS+ GBE group was lower than that of the CUMS+ Veh group ( P<0.01). (3) The results of whole-cell recording showed that the interaction of GBE×CUMS of frequency and quantification of sEPSC in the four groups were significant ( F=5.45, 6.94, both P<0.05). The sEPSC frequency and quantification in the CUMS+ Veh group were lower than those in the CTRL+ Veh group (both P<0.01), and the sEPSC frequency and quantification in CUMS+ GBE group were higher than those of CUMS+ Veh group (both P<0.05). The interaction of GBE×CUMS of frequency and quantification of sIPSC in the four groups were significant ( F=7.78, 8.96, both P<0.01). The sIPSC frequency and quantification of the CUMS+ Veh group were higher than those of CTRL+ Veh group (both P<0.01), and the above indexes of CUMS+ GBE group were lower than those of CUMS+ Veh group (both P<0.01). As for the sEPSC/sIPSC ratio, GBE×CUMS interaction was significant ( F=5.45, P=0.02). The sEPSC/sIPSC ratio of CUMS+ Veh group (0.09±0.01) was lower than that of CTRL+ Veh group (0.28±0.04) ( P<0.01), and the sEPSC/sIPSC ratio of CUMS+ GBE group (0.14±0.03) was higher than that of CUMS+ Veh group ( P<0.05). Conclusion:Ginkgo biloba extract can improve the depression-like behavior of mice induced by CUMS, reduce the oxidative stress of mPFC and improve the excitation/inhibition balance of pyramidal neurons in depressive model mice.
