Carotenoids play an important role in regulating the hydrogen production of hydrogen-producing Rhodobacter sp. The carotenoids of hydrogen-producing Rhodobacter sp. grown in acetate medium were extracted by using acetone-methanol (7∶2,V/V) solvent and were separated by using thin-layer chromatography on silica-gel plate. The qualitative and quantitative of the carotenoids were analyzed by spectrometry. The results showed that the carotenoids were completely extracted three times with acetone-methanol (7∶2,V/V) in two hours. The ultrasonication had little effect on yield of carotenoids. The yield of carotenoids was 2.81mg/g wet cell. There were 4 spots on the silica-gel plate in the order of yellow, red, light red and light yellow. Yellow spot and red spot were the dominant composition of carotenoid in Rhodobacter sp. The spectrometry data showed that the yellow and red component might be the spheroidene and spirilloanthin respectively.

Mutagenesis and screening of hydrogen-producing photosynthetic bacteria,Rhodobacter sp.R7 strain,was investigated by using the combination mutation of ultraviolet ray and LiCl and layer plating methods.A carotenoid mutant named R726 strain was obtained.The plate phenotype properties in carotenoid mutant were different from that of parent strains.Living cells spectra showed that absorption peak of 550 nm was appeared in carotenoid mutant,but not in parent strain.The absorption spectra of extraction of pigment further confirmed the difference of carotenoid composition between the mutant and parent strains.The result of TLC on silica gel plate showed that mutant has a lack of yellow carotenoid composition which occurs in parent strain.H_2 productivity and biomass in carotenoid mutant was higher than that of parent strain.These results revealed that mutant has a modified carotenoid biosynthesis pathway.

Chronic viral hepatitis B (CHB) is a major infectious disease greatly harmful to the health of Chinese people. Chinese medicine has its speciality and advantages in treating it depending syndrome-differentiation. The objectified researches regarding Chinese medical syndromes in CHB heretofore were reviewed in this article. Moreover, aiming at existing problems and taking the angle of "disease-syndrome combining" study, authors put forward research approach, and approaches for studying systemic biology based biological basis of Chinese medical syndrome in hepatitis B with reductionism and holism, cybernetics and system theories in combination.

To provide accurate information on geographic distribution of crude drug Sailonggu in the plateau, we identified zokor species (Eospalax spp.) in Qinghai-Tibet Plateau using molecular methods. Based on the mitochondrial cytochrome B (cytb) gene sequences, we then extracted haplotypes from these sequences and reconstructed phylogenetic trees for the haplotypes using both maximum likelihood (ML) and Bayesian inference (BI) methods. Based on the trees, the species of each sample were determined. Five hundred and three samples from 35 populations were sequenced and their whole cytb sequences (1140 bp) were obtained. From these sequences 150 haplotypes were detected, in which, 126 were Eospalax baileyi, 20 were E. cansus, and 4 were E. smithi of the 35 populations, 28 were E. baileyi type, 5 were E. cansus type, and the remaining 2 were mixed of E. baileyi + E. cansus (DT2) and E. baileyi + E. smithi (ZN3). The results showed that, the regions around the Qinghai lake and near the upper stream of Yellow River started at Guide could be viewed as the producing area of authentic Sailonggu, and also, the cytb gene is a powerful molecular marker to determine the species of zokors as well as for the authentication of geographic distribution of Sailonggu.

Objective To explore the clinical value of expression levels of serum COX-2 in patients with advanced NSCLC before and after EGFR-TKI treatment. Methods The serum was collected from 58 cases. Before and after targeted therapy , the serum COX-2 level was examined by ELISA. Meanwhile , CT scan was exercised to evaluate the treatment. Follow-up interview was done. The relationship among the change in expression level of serum COX-2 , efficacy and PFS was analyzed. Results The serum COX-2 level significantly decreased in the response group (t = 11.258, P = 0.000) and increased in the PD group (t = -7.759, P =0.000) after EGFR-TKI treatment, and not significantly changed in the SD group (t = 1.424, P = 0.170). Before treatment, the baseline serum COX-2 level in the response group was significantly higher than that in the SD group and the PD group (F = 20.852, P = 0.000 ). Before the targeted therapy, the higher the level of serum COX-2 was, the longer PFS patients would enjoy. Conclusion Detection of the serum COX-2 contributes to the judgment of therapeutic effect of EGFR-TKI and can be used as a prediction of EGFR-TKI drugs outcomes for patients with advanced NSCLC.

BACKGROUND: Interleukin-1 (IL-1β) and intercellular adhesion molecule-1 (ICAM-1 ) can mediate neutrophilic infiltration, which is closely relevant to cerebral ischemia-reperfusion injury.OBJECTIVE: To investigate the effect of physcion on cerebral inflammatory reaction after ischemia-reperfusion injury.DESIGN: A completely randomized study based on animals.SETTING: Neurological department in a university hospital.MATERIALS: From September to December 2003, the study was conducted in the Animal Laboratory, Hebei Staff and Workers Medical College. Totally 91 healthy male SD rats, supplied by Laboratory Animal Center of Hebei Medical University, were used in the experiments. They were divided into sham operation (SO) group, ischemia-reperfusion group, normal control group, 20 mg/kg physcion group and 40 mg/kg physcion group.Each of the former two groups would be divided into 4 subgroups named as the 6th-hour-after-reperfusion group, the 12th-hour-after-reperfusion group, the 24th-hour-after-reperfusion group and the 48th-hour-after-reperfusion group. Each of the latter two groups were divided into 2 subgroups named as the 12thhour-after-reperfusion group and the 24th-hour-after-reperfusion group. Each subgroup contained 7 rats.INTERVENTIONS: Middle cerebral artery occlusion model (MCAO model) was applied, and IL-1β was measured by radioimmunoassay and ICAM-1 was detected by immunohistochemical staining.MAIN OUTCOME MEASUREMENTS: The IL-1 β level and the positive expression of ICAM-1 in the rats' cerebella were observed.RESULTS: Cerebral ischemia-reperfusion injury in the rats reached its peak 6 hours after reperfusion, and then it decreased gradually. In the 12-hour-after-reperfusion subgroup amd the 24-hour-after-reperfusion subgroup of the 40 mg/kg physcion group, and the 12-hour-after-reperfusion subgroup of the 20 mg/kg physcion group, IL-1β in the injured parts of the cerebella decreased dramatically, compared with MCAO model controls ( P＜ 0.01 ). In the normal control group and SO group, a small quantity of ICAM-1 was detected in rat' s cerebral cortex, and some fulvous staining substance was observed in the plasma and membrane of cerebral vascular endothelium cells. In the cerebral ischemia-reperfusion injury group, positive staining substance could be observed 24 hours after the reperfusion, then darkened gradually (integral absorbency value: 31.89 ± 4.38, area density value: 0. 018 5 ± 0. 003 1). In the 12-hour-after-reperfusion subgroup of the 40 mg/kg physcion group (integral absorbency value: 13.33 ±6. 12, area density value: 0. 007 6 ± 0. 002 2) and the 24-hour-after-reperfusion subgroup of the 40 mg/kg physcion group (integral absorbency value: 20.04 ±4.65,area density value: 0. 012 9 ±0. 003 6), and in the 24-hour-after-reperfusion subgroup of the 20 mg/kg physcion group (integral absorbency value:23.73 ±4.51 area density value: 0. 014 1 ±0. 003 8), expressions of ICAM-1 around the infarctions significantly decreased as compared with those in the MCAO model controls respectively ( P ＜ 0.01 or P ＜ 0.05).CONCLUSION: Physcion tends to decrease the expressing of IL-1β and ICAM-1 in a cerebellum after ischemia-reperfusion injury, thus, it may help alleviate the ischemia-reperfusion injury.
