Endophytic fungi Penicillium dangeardii, isolated from Lysidice rhodostegia Hance root, was fermented and the secondary metabolites were studied. By means of Sephadex LH-20 column chromatography, ODS column chromatography and PHPLC over the fermented culture, 5 compounds were isolated. By using ESI-MS and NMR, the structures of the compounds were determined as N-[9-(β- D-ribofuranosyl)-9H-purin-6-yl]-L-aspartic acid (1), 3-caffeoylquinic acid (2), 4-caffeoylquinic acid (3), and 5-caffeoylquinic acid (4), 3-hydroxy-benzoic acid-4-O-β-D-glucopyranoside (5).

5.The different roles of the spinal protein nNOS and iNOS in morphine naloxone-precipitated withdrawal response.
Chinese Journal of Applied Physiology 2012;28(3):249-253
OBJECTIVETo explore the effects of intrathecal injection of neuronal nitric oxide synthase (nNOS) inhibitors 7-Nitroindazole (7-Ni) and inducible nitric oxide synthase(iNOS) inhibitors aminoguanidine (AG) on the behavioral changes of morphine-induced dependent and withdrawal rats; the expression of Fos, nNOS and iNOS in spinal cord.
METHODSTo set up morphine dependence model, rats were subcutaneously injected with morphine (twice a day, for 5 d). The dose of morphine was 10 mg/kg in the first day and was increased by 10 mg/ kg every day. On day 6, 4 h after the injection of morphine (50 mg/kg), morphine withdrawal syndrome was precipitated by an injection of naloxone (4 mg/kg ip). 7-Ni, an nNOS inhibitor or iNOS inhibitors AG were intrathecally injected 30 min before the administration of naloxone respectively. The scores of morphine withdrawal symptom and morphine withdrawal-induced allodynia were observed. One hour after naloxone-precipitated withdrawal, Fos protein expression was assessed by immunohistochemical analysis and Western blot was used to detect the expression of nNOS and iNOS in the rat spinal cord.
RESULTSIntrathecal administration of nNOS inhibitor 7-Ni and iNOS inhibitors AG decreased the scores of morphine withdrawal, attenuated morphine withdrawal-induced allodynia and also inhibited the increase of Fos protein expression in the spinal cord of morphine withdrawal rats. nNOS and iNOS positive neurons in dorsal horn in nNOS group and iNOS group were significantly lower than that in withdrawal group. Compared with withdrawal group, level of nNOS and iNOS protein in spinal cord in nNOS group and iNOS group were significantly lower.
CONCLUSIONIt is suggested that nNOS and iNOS in the spinal cord may contribute to naloxone-precipitated withdrawal in rats and may play different roles in the above-mentioned effect.

Objective To investigate the feasibility of using low Kv,low iodine contrast Agent concentration (dual low)CT scan techniques in Coronary CTA (CCTA).Methods Seventy-six patients undergoing CCTA were divided into Group A and Group B , randomly.Group A (38 patients)was the dual-low group,which was scanned with tube voltage of 100 kVp,and injected with iso-osmolarity contrast agent visipaque 270 (270 mg I/mL),with iterative reconstruction technique (ASIR 40%).Group B (38 pa-tients)was scanned with 120 kVp,and low osmolarity contrast agent omnipaque 350 (350 mg I/mL)and FBP reconstruction,The images are assessed double-blindly by two experienced radiologists.Five ROIs were placed onto the ascending root of aorta (AO), left main artery(LM),left anterior descending (LAD),left circumflex artery(LCX),right coronary artery (RCA),and the image qualities are evaluated objectively using CT values,noise,signal noise ratio (SNR),contrast noise ratio (CNR),and compared sta-tistically using Paired t-test.The radiation dosages,such as CTDIvol,DLP and ED were also recorded and compared with Paired t-test.Results CTDIvol,DLP and ED of Group A (dual low)decreased 35.7%,38.6% and 38.6% respectively compared with Group B,the iodine intake decreased 22.9%.While the image qualities of the two groups were not significantly different,all images are good enough for diagnosis,with Group A slightly better than Group B in radiologists’scores.Conclusion Voltage 100 kVp, combined with low contrast agent concentration of 270 mg I/mL can fully satisfy the diagnostics need in CCTA,and significantly lower both the radiation dosage and iodine intake.

Objective To explore the effect of Okam on airway inflammation in asthmatic mouse.Methods Thirty-two SPF grade Kunming Strain mice were randomly divided into positive control group,glucocorticoid inhalation group,Okam group and negative control group with 8 mice in each group.The mice were sensitized and repeatedly challenged with ovalbumin(OVA) to establish the models of chronic asthma.The glucocorticoid group were given Budesonide(200 ?g) and saline everyday by inhalation,the Okam group were given 50 mg/kg Okam by gavage,and the positive group had saline at the same time,the negative control group received saline at all stages.The inflammation of the lung tissue were scored underwent HE staining.Bronchoalveolar lavage fluid(BALF) cell count and differential were studied,and interferon-?(IFN-?),interleukin-4(IL-4) in BALF were determined by enzyme-linked immunosorbent assay(ELISA).Results There were no inflammatory cell infiltrate of bronchiole in the negative control group.Inflammatory infiltration of lung tissue were obvious in the positive control group.Inflammatory infiltration of lung tissue lightened obviously in the Budesonide and Okam groups.The total cell number,Eosinophils(EOS) and IL-4 level in BALF,and the score of the lung tissue in Okam group were all markedly lower than those in positive control group(t=5.942,7.089,7.078 Pa0.05),IFN-? lower(t=4.275 P

OBJECTIVE:
To study DNA quantification and STR typing of samples pre-treated with pyramidon.
METHODS:
The blood samples of ten unrelated individuals were anticoagulated in EDTA. The blood stains were made on the filter paper. The experimental groups were divided into six groups in accordance with the storage time, 30 min, 1 h, 3 h, 6 h, 12 h and 24h after pre-treated with pyramidon. DNA was extracted by three methods: magnetic bead-based extraction, QIAcube DNA purification method and Chelex-100 method. The quantification of DNA was made by fluorescent quantitative PCR. STR typing was detected by PCR-STR fluorescent technology.
RESULTS:
In the same DNA extraction method, the sample DNA decreased gradually with times after pre-treatment with pyramidon. In the same storage time, the DNA quantification in different extraction methods had significant differences. Sixteen loci DNA typing were detected in 90.56% of samples.
CONCLUSION
Pyramidon pre-treatment could cause DNA degradation, but effective STR typing can be achieved within 24 h. The magnetic bead-based extraction is the best method for STR profiling and DNA extraction.

OBJECTIVETo study the clinical efficacy and adverse reaction of comprehensive therapy mainly with Chinese anti-cancer medicinal perfusion/embolization and assisted with Chinese drug-therapy based on TCM Syndrome Differentiation in treating primary liver cancer.
METHODSForty-one patients with liver cancer were divided into the treated group and the control group. To the treated group turmeric oil microballoon, cinobufotalin, Aidi injection and iodized oil were given via hepatic artery perfusion/embolization, and to the control group chemotherapeutic agents and iodized oil were given for instead. Besides, both groups were given Chinese herbs according to TCM Syndrome Differentiation additionally.
RESULTSThe tumor inhibitory rate in the treated group and the control group was 77.78% and 69.57% respectively, with insignificant difference between them. The improvement of fatigue and anorexia in the treated group was better than that in the control group (P < 0. 05). The 6-month, 12-month and 24-month survival rate in the treated group and control group was 61.11% vs 56.62%, 27.78% vs 30.43% and 22.22% vs 26.09%, respectively, the difference between the two groups was insignificant. The occurrence of adverse reactions such as decreasing of white blood cells, platelet and hemoglobin, nausea and vomiting were obviously lower in the treated group than those in the control group (P < 0.05).
CONCLUSIONChinese anti-cancer medicinal perfusion/embolization has affirmative short-term clinical effect in treating primary liver cancer with few adverse reactions, which was tolerable to patients, but its long-term clinical efficacy needs further observation.
