Objective To increase the ultimate yield of periplocin in Periploca sepium adventitious root cultures by a two-stage culture based on nitrogen source.Methods Firstly,the effects of nitrogen source(NH<'+><,4>-NO<'-><,3>-)at different ratios and different total initial nitrogen amounts on the accumulation of biomass and secondary metabolites in adventitious root cultures of P sepium were investigated,and growth and production media for the two-stage culture based on the above results were established.Results The highest biomass and periplocin content were obtained in the culture medium of 15 mmol/L total nitrogen amount with NH<'+><,4>-NO<,3>(1:2)and 30 mmol/L total nitrogen amount with nitrate as the sole nitrogen source.By adopting a fed-batch cultivation strategy,the dry weight adventitious root,periplocin content and yield were increased by 136%,108%,and 389%,respectively when compared with those of the control,reaching up to 8.13 g/L,157.15 μg/g,and 1277.63 μg/L,respectively.Furthermore,it was found that in the process of two-stage culture,the adventitious roots grew thicker significantly after they were transferred into production medium directly.Conclusion The ultimate yield of periplocin in P.sepium adventitious root cultures could be significantly increased by a two-stage culture based on nitrogen source.

Objective To explore the characteristics of chromosome karyotypes in patients with chronic myeloid leukemia (CML),and to provide help to individualized treatment.Methods The date of chromosome karyotypes of 313 patients and FISH of 45 of these patients with CML excluding Ph chromosome negative (Ph-) after treatment were collected from January 2014 to June 2015.Karyotypes were detected by R-banding.Results In the 313 cases,307 cases (98.08 ％) were Ph chromosome positive (Ph+) and 6 cases (1.92 ％) were Ph-.In the Ph+ patients,288 cases (93.81％) were classical Ph+,and 19 cases (6.19 ％) were variant rearrangements.There were 48 cases (15.34 ％) with additional chromosome changes in all patients,including 41 cases (13.10 ％) with classical Ph+ and 7 cases (2.24 ％) with variant rearrangements.The most common additional chromosome changes were in the following order:+der(22) Ph (35.42 ％),+8 (33.33 ％) and +21 (12.50 ％).The most frequent pattern of combination was +der(22) combined with +8 (16.67 ％),followed by +8 combined with +21 (10.42 ％).The proportion of pure Ph+ patients in chronic phase was higher than that of advanced phase,but proportion of classical Ph+ patients with additional chromosome changes in chronic phase was lower than that in advanced phase (x2 =1 11.55,P ＜ 0.01).The proportions of chronic phase and advanced phase patients with simple variant rearrangements were not different from those with complex variant rearrangements (P =0.582).The results of FISH in 45 cases were all positive,including 5 cases with 2 GIR1Y.Conclusion Karyotype analysis can reveal the instability of genetic and the characteristics of disease progression by identifying the evolution of Ph,which provides the basis for clinical doctors to choose suitable treatment.

BACKGROUND: Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index ( EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS: Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS: The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS: RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

Objective To observe the relationship between serum level of H-FABP before percutaneous coronary intervention (PCI) and prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Methods A total of 104 cases were recruited in this study. PCI was performed 12 h after onset. The concentration of H-FABP was detected before operation. Gensini score system was used to calculate the integral of all patients after coronary angiography. According to Gensini score, patients were divided into three groups, 34 cases in group A (8≤Gensini scores<41), 34 cases in group B (41≤Gensini scores<64) and 36 cases in group C (Gensini scores≥64). Indicators were analyzed statistically including systolic blood pressure (SBP), diastolic blood pressure (DBP), smoking history, H-FABP, left ventricular ejection fraction (LVEF), total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), fasting blood sugar, diabetes (DM) and hypertension. The patients were followed up for 12 months after operation. According to the occurrence of major adverse cardiovascular events (MACE), patients were divided into MACE group and non-MACE group. The related factors of two groups were statistically analyzed. The multivariate Logistic regression analysis was used to screen the risk factors of MACE for patients with STEMI after emergency PCI. Results There is a gradually increasing tendency in total cholesterol levels among three A, B and C groups (P<0.05). LVEF values were lower in B group and C group than that of A group (P<0.05). There were no significant differences in levels of SBP, DBP, H-FABP, TG, HDL-C, LDL-C, fasting plasma glucose and smoking history, DM, and hypertension between three groups (P>0.05). In 12-month follow-up, the proportion of STEM combined with DM, the time from onset to PCI, the level of TC, the level of H-FABP before operation and Gensini score were significantly higher in MACE group than those of non-MACE group (P<0.05). Logistic regression analysis showed that STEM combined with DM, higher serum level of H-FABP before operation were risk factors of MACE in 12-month after operation (P<0.05). Conclusion For patients with acute STEM combined with diabetes and elevated preoperative serum level of H-FABP, be alert to the occurrence of MACE in 12-month after PCI.

Objective:To compare the effects of 3 different crystalloid fluids at different osmotic concentrations on blood-brain barrier(BBB) and brain edema in severe hemorrhagic shock rats.Methods: A total of 150 male SD rats were equally randomized into a lactated Ringers(LR) group,a 7.2% hypertonic saline(HS) group and a plasmalyte A(PA) group.LR,PA and HS were administered after an hour of severe hemorrhagic shock induced by drawing out about 40% of total blood and maintaining MAP at 35-45 mmHg.Serum S100B,cerebra1 Evans Blue(EB) and water content were determined before(T_0) and 1 h after bleeding(T_1) and immediately(T_2),1 h(T_3) and 2 h(T_4) after administration.The changes of BBB in the hippocampus CA1 area were observed by electron microscopy.Results: The serum S100B level was obviously higher at T_1,T_2,T_3 and T_4than at T_0 in all groups(P0.05).The cerebra1 water content was significantly increased at T_1,T_2,T_3 and T_4in the LR group,at T_1in the HS and at T_1,T_2 and T_3 in the PA as compared with T_0(P
