To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

AIM:To evaluate the effect of curcumin on impaired learning-memory ability and the expression of high mobility group box protein 1 ( HMGB1 ) and c-Jun N-terminal kinase ( JNK ) in a rat model of Alzheimer disease (AD).METHODS:Male Sprague-Dawley rats, weighing 250~270 g, were randomly divided into 4 groups (n=9):blank control group (group A), model group (group B), curcumin treatment group (group C, curcumin injected intraper-itoneally at 100 mg· kg-1· d-1 for 6 consecutive days) and solvent control group (group D).The rats of AD model were induced by injection of ibotenic acid into the nucleus basalis of Meynert ( NBM) bilaterally.All rats were trained in Morris maze to assess the ability of learning and memory .The expression of HMGB1 and JNK in the hippocampus was detected by the methods of immunohistochemistry and Western blotting .RESULTS:Compared with group A , the average escape laten-cy (AEL) in groups B and D were obviously longer (P<0.05), while AEL in group C in the 5th and 6th days were signif-icantly shorter (P<0.05).The releases of HMGB1 in the CA1 and CA3 areas in groups B and D from the nucleus were a-bundant.Compared with groups B and D , HMGB1 in hippocampal CA1 and CA3 areas in group C secreted out of the nu-cleus decreased obviously (P<0.05).No significant difference of the release of HMGB1 between group A and group C was observed (P>0.05).No significant difference in the expression of HMGB1 in the hippocampus among the 4 groups was found (P>0.05).However, compared with groups B and D , the expression of JNK in group C was decreased obvi-ously (P<0.05).CONCLUSION: Curcumin significantly improves the learning and memory ability of AD rats .The probable mechanisms may be related to inhibiting the release of HMGB 1 from the nucleus of hippocampal neurons and de-creasing the expression of JNK in the hippocampus .

Objective To investigate the effect of progressive neurological deterioration ( PND) of cerebral watershed infarction on early prognosis. Methods The consecutive patients with cerebral watershed infarction admitted in the Department of Neurology,Jinling Hospital,Nanjing University School of Medicine and their cerebral watershed infarctions confirmed by the imaging examination from March 2009 to March 2014 were enrolled. The clinical features, laboratory indicators and imaging features of internal watershed infarction,cortical-type watershed infarction,and mixed watershed infarction were identified and analyzed. The National Institutes of Health Stroke Scale was used to score neurological deficit. The modified Rankin scale ( mRS) was used to score the prognosis of patients. Single factor analysis was used to compare the differences between the groups. At the same time,the correlation between PND and poor prognosis of cerebral watershed infarction at day 90 was analyzed by multivariable Logistic regression analysis. Results A total of 89 patients with cerebral watershed infarction were enrolled,including 43 cortical-type watershed infarctions,36 internal watershed infarctions, and 10 mixed watershed infarctions. Single factor analysis indicated that the incidences of PND of internal watershed infarction and mixed watershed infarction were significantly higher than the cortical-type watershed infarction (36. 1% [n=13],50. 0% [n=5], and 16. 3% [n=7],respectively;P=0. 018). At day 90,28 patients had poor prognosis,and mRS was (3.4±1. 0) scores at day 90. There was significant difference in the types of infarction between the patients with poor prognosis and patients with good prognosis (P<0. 05). In patients with poor prognosis, most of them were internal watershed infarctions,accounting for 50. 0% (14/28),while in patients with good prognosis,most of them were cortical-type watershed infarctions(57. 4% [35/61]). The incidence of PND in patients with poor prognosis was significantly higher than that in patients with good prognosis (57.1% [16/28] vs. 14. 8% [9/61];P<0. 05). The result of multivariate Logistic regression analysis showed that after adjustment for confounding factor, PND was independently associated with the poor prognosis of cerebral watershed infarction at day 90 (OR 6. 969,95%CI 2. 451-19. 869;P<0. 01). Conclusion Compared with the cortical-type watershed infarction, the patients with internal watershed infarction is more prone to have PND, and PND is independently correlate with the poor prognosis at day 90.

Objective To investigate the effects of different doses of ulinastatin on severe thermal injuryinduced myocardial damage in rats. Methods One hundred and eighty female SD rats weighing 180-220 g were usedin this study. Thirty percent of the total body surface (TBS) was shaved chemically with 20% sodium sulphate and then exposed to 92 ℃ water for 18 s. The animals with third degree thermal injury involving 30% of the TBS were randomly divided into 3 groups (n = 60 each): group Ⅰ thermal injury (group TI); group Ⅱ and Ⅲ received intraperitoneal ulinastatin 40 000 and 80 000 U/kg respectively immediately after thermal injury (group U1 , U2). The TI group received equal volume of normal saline IP instead of ulinastatin. Blood samples were taken from abdominal aorta before (baseline) and at 1, 3, 6, 12 h after thermal injury for determination of serum concentrations of cTnI, IL-1β, IL-6, IL-10 and TNF-α (10 samples at each time points). Ten animals were sacrificed at each time point after blood sampling. The myocardial specimens were obtained for microscopic examination and measurement of MDA content and SOD activity. Results Compared with group TI, the serum concentrations of cTnI, IL-1β, IL-6 and TNF-α and MDA content in myocardium were significantly decreased and the myocardial SOD activity was significantly increased in group U1 , while in group U2 the senum concentrations of cTnI, IL-Iβ, IL-6 and TNF-α and myocardial MDA content were significantly increased and the myocardial SOD activity was significantly decreased. There was no siginificant difference in the serum concentrations of IL-10 among the three groups. Microscopic examination showed that myocardial damage was accentuated in group U2 as compared with group U1. Conclusion Ulinastatin 40 000 U/kg can ameliorate severe thermal injury-induced myocardial injury through inhibition of inflammatory response and lipid peroxidation response, whereas ulinastatin 80 000 U/kg accentuates myocardial damage.
