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.

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.

Objective To investigate the prognostic significance of postoperative radiotherapy (PORT) for locally advanced pulmonary adenocarcinoma with micropapillary pattern(MPPAC).Methods A total of 45 completely resected pN2-3 cases that occured from January 2012 to December 2014 at Tianjin Medical University Cancer Hospital were retrospectively analyzed.All of them were diagnosed with MPPAC by pathological diagnosis.Based on whether receiving PORT, patients were divided into radiotherapy and non-radiotherapy groups.General characteristics, overall survival and disease-free survival characteristics of the two groups were compared, respectively.Results The median overall survival (OS) of patients was 19.8 months, 1-year and 2-year overall survival rate was 79.4％ and 30.3％ , respectively.The median disease free survival (DFS) of patients was 13 months, 1-year and 2-year, and the disease free survival rate was 59.3％ and 28.9％ , respectively.The radiotherapy and non-radiotherapy groups exhibited median OS of 22.3 and 11.4 months,respectively (x2=13.329, P＜ 0.05) , and corresponding D FS of 16.2 and 10.4 months(x2 =7.972 ,P ＜0.05).The epidermal growth factor receptor gene (EGFR) mutation rate of patients was 57.14％ (20/35), In the subgroup analysis, for patients with EGFR mutation, the radiotherapy and non-radiotherapy groups showed median OS of 25.6 and 18.4 months, respectively(x2 =9.268,P ＜ 0.05) , and corresponding DFS of 21.6 and 12.6 months (P ＞ 0.05).For patients with wildtype EGFR, the radiotherapy and non-radiotherapy groups showed median OS of 21.8 and 10.6 months,respectively(x2 =9.595,P ＜ 0.05) , and corresponding DFS of 15.2 and 6.6 months(x2 =4.538,P ＜0.05).Conclusions PORT could improve survival of patients with pN2.3 MPPAC.For patients with locally advanced MPPAC after curative resection, PORT is still an integral part of treatment.

BACKGROUND:There are several routes for stem cel transplantation;however, it is stil unable to determine which one is the best. As for the different individuals with brain injury, the type of transplanted cel s, transplantation route and time wil affect the therapeutic effects.
OBJECTIVE:To investigate the effect of bone marrow mononuclear cel s transplanted via different approaches on neurological function of rats with traumatic brain injury.
METHODS:Bone marrow mononuclear cel s of rats were administered gradient centrifugation with Ficol lymphocyte separation medium, and were labeled with CFDA-SE in vitro as standby. Rat models of traumatic brain injury were established by the method of freefal . After successful establishment of rat models, bone marrow mononuclear cel s labeled with CFDA-SE were immediately transplanted into rats via injured area, lateral ventricle and internal carotid artery. One control group was designated for each transplantation route (bone marrow mononuclear cel s were replaced with the same volume of DMEM). The degree of neurological deficits was evaluated using mNSS scores at different time points after treatment. The brain tissue was harvested after the last neurobehavioral evaluation. The survival and migration of bone marrow mononuclear cel s in the injured area were observed under an inverted fluorescent microscope.
RESULTS AND CONCLUSION:At 7, 10, and 14 days after treatment, the mNSS scores of rats in al groups were al lower than those at 1 and 3 days (P<0.05). At 7 and 10 days, the mNSS scores of rats in the internal carotid artery transplantation group were significantly lower than those in the control group (P<0.05). At 14 days after treatment, the number of fluorescence-labeled cel s of rats in the internal carotid artery transplantation group was greater than that in the other groups (P<0.05) and these labeled cel s were widely distributed. The results demonstrate that the neurological function of rats can be improved by transplanting bone marrow mononuclear cel s via the internal carotid artery, and a large number of transplanted cel s can survive and migrate in the injured area.

AIM: To explore the effect of physcion (P) on the level of IL-1? and expression of ICAM-1 and caspase-3 during cerebral ischemia-reperfusion injury. METHODS: The 91 healthy adult SD rats were selected, and were randomly divided into normal group, sham-operated group, cerebral ischemia-reperfusion group (model), low-dose physcion (PLD) and high-dose physcion (PHD) treatment group. The level of IL-1? was detected by radioimmunoassay. The expression of ICAM-1 and caspase-3 was detected by immunohistochemistry. The changes of tissue pathology were also investigated. RESULTS: The level of IL-1? reached the peak at 6 h after ischemia-reperfusion (IR). The protein expression of ICAM-1 and caspase-3 reached the peak at 24 h after IR. The level of IL-1? and the protein expression of ICAM-1 and caspase-3 in PHD group decreased obviously compared with those in model group (P

Objective To analyze the factors affecting the efficacy of postoperative radiotherapy (PORT) in node-positive non-small cell lung cancer (NSCLC). Methods 480 patients with stage N_1-N_2 NSCLC after radical surgery were retrospectively reviewed. Of them, 267 patients received adjuvant chemotherapy and 121 received PORT. All patients were grouped based on the N stage, tumor size and lymph node positive ratio (the percentage of positive lymph nodes from the detected lymph nodes, LNPR). Group 1 included patients with tumor size ≤3 cm and LNPR ≤33%, group 2 was tumor size > 3 cm or LNPR > 33%, and group 3 was tumor size > 3 cm and LNPR > 33%. The endpoints were the local recurrence free survival (LRFS) and overall survival (OS). Kaplan-Meier method and Cox's proportional hazards regression model were used for the statistic analyses. Results PORT improved the overall survival only in patients with N_2 disease. Both tumor size and LNPR significantly influenced the efficacy of PORT. The 5-year LRFS for patients with vs. without PORT in the group 1, 2 and 3 were 55% vs. 60% (χ~2 = 0.03,P-0.869), 42% vs. 50% (χ~2 =0.31,P=0.547),and 62% vs. 52% (χ~2=4.25,P=0.036), respectively;and the corresponding OS were 22% vs. 50% (χ~2 = 1.65 ,P =0. 199), 26% vs. 22% (χ~2= 0. 13,P=0.786) and 42% vs. 16% (χ~2= 15.33,P=0.000), respectively. Conclusions Tumor size and LNPR significantly impact the efficacy of PORT . For patients with stage N_2 NSCLC , PORT could improve local recurrence free survival and overall survival when tumor size > 3 cm and LNPR >33%.
