AIM To investigate the neuroprotective effects and possible mechanisms of saponins from Anemarrhena asphodeloides Bge. (SAaB) on neuronal damage induced by amyloid β-protein fragments 25-35 (Aβ25-35). METHODS Cultured mouse peritoneal macrophages were stimulated with Aβ25-35 (20 μmol·L-1) for 0.5, 1, 2 and 6 h or preincubated with SAaB (10, 30 and 100 μmol·L-1)for 10 min or mitogen-activated protein kinase (MAPK) specific inhibitors (p38 MAPK inhibitor SB 203580 and MEK specific inhibitor PD98059) for 30 min prior to the addition of Aβ25-35(20 μmol·L-1). After stimulation with Aβ25-35 for the indicated times, total cellular extracts were prepared for Western blotting of extracellular signal-regulated kinase (ERK) and p38 MAPK. After stimulation with Aβ25-35 for 48 h, the supernatants of cultured macrophages were collected for quantification of tumor necrosis factor-α (TNF-α) and nitric oxide (NO) and protein expression of inducible nitric oxide synthase (iNOS) in macrophages was determined by immunocytochemical staining. To determine whether SAaB has protective effect against neuronal apoptosis mediated by Aβ25-35-induced macrophages activation, macrophages were stimulated with Aβ25-35 in the presence or absence of SAaB (10, 30 and 100 μmol·L-1) for 48 h and then the cell-free supernatant of Aβ25-35-stimulated macrophages was transferred to the culture of cerebellar granule neurons for 72 h. Neuronal apoptosis was quantitated by scoring the percentage of cells with apoptotic nuclear morphology after Hoechst 33258 staining. RESULTS Aβ25-35(20 μmol·L-1) significantly induced increase in phospho-ERK1/2 and phospho-p38 MAPK protein expression without affecting total protein levels and in the production of TNF-α and NO in cultured macrophages. Aβ25-35-induced increase of TNF-α production in macrophages involved activation of ERK1/2 signal pathway. Importantly, TNF-α and NO generated by cultured macrophages after Aβ25-35 stimulation may be responsible for the majority of the neuronal apoptosis. SAaB (30 and 100 μmol·L-1) significantly suppressed Aβ25-35-induced increase in phospho-ERK1/2 and phospho-p38 MAPK protein. In addition, SAaB (10, 30 and 100 μmol·L-1) also decreased the level of TNF-α and NO in supernatants of cultured macrophage and inhibited Aβ25-35-induced increase in iNOS protein expression of macrophages. Neuronal apoptosis mediated by Aβ25-35-induced macrophage activation was also significantly attenuated by treatment with SAaB (10, 30 and 100 μmol·L-1). CONCLUSION SAaB protects neurons against the neuronal cell death induced by Aβ25-35. The beneficial effects of SAaB may be related to the reduction of TNF-α and NO from activated macrophage induced by Aβ25-35.

Objective To explore the clinical significance of the serum brain?derived neurotrophic factor( BDNF) level in severe neonatal hyperbilirubinemia. Methods One hundred and twenty term and birth weight>2500 g infants admitted to the Neonatal Intensive Care Unit of Bethune nternational Peace Hospital of People Liberation Army were divided into severe hyperbilirubinemia group and control group according to their total bilirubin concentration. Total bilirubin( TBIL) concentration,BDNF and albumin in serum were determined in two groups. In addition, craniocerebral MRI was performed in severe neonatal hyperbilirubinemia before discharge. The correlation of the BDNF, TBIL, B/A, MRI results between severe hyperbilirubinemia group and control group were compared. Results The serum BDNF levels in severe hyperbilirubinemia group was ( 8. 84 ±3. 26) μg/L,significantly higher than that in control group((6. 24±1. 71) μg/L,t=3. 88,P<0. 05). In severe hyperbilirubinemia group,BDNF level was positively correlated with B/A level(r=0. 429,P<0. 05),but there was no correlation between BDNF and total bilirubin level(r=0. 278,P>0. 05). The serum BDNF level with craniocerebral MRI abnormal was ( 9. 53 ± 2. 77 ) μg/L, higher than that with craniocerebral MRI abnormal ((7. 81±3. 76) μg/L),but there was no statistical difference between them(t=1. 439,P>0. 05). Conclusion In severe neonatal hyperbilirubinemia, the body can secrete BDNF increasely. BDNF level is positivelycorrelated with B/ A level. As a marker of brain damage,BDNF is sensitive than craniocerebral MRI.

Objective Both decreased glomerular filtration rate (GFR) and arterial stiffness were considered as risk factors for atherosclerosis. Previous studies have suggested the association between central arterial stiffness and the degree of GFR loss. Whether decreased GFR contributes to peripheral artery stiffness remains controversial. Moreover, data analyzed from a cohort of Chinese women are rare. Our aim was to explore the relationship between GFR and regional arterial stiffness in Chinese women. Methods In this cross-sectional study, we randomly recruited 1131 adult women residents with GFR ≥ 60 mL/min per 1.73 m2 estimated by the Chinese Modification of Diet in Renal Disease equation from three large communities. Central and peripheral arterial stiffness were estimated simultaneously by measuring carotid-femoral pulse wave velocity (PWVcf) and carotid-radial PWV (PWVcr) using a validated automatic device. Augmentation Index at heart rate 75 beats/minutes (AIx-75) was measured by pulse wave analysis as a composite parameter reflecting both large and distal arterial properties. Results The mean estimated GFR (eGFR) of the study group was 100.05 ± 23.26 mL/minute per 1.73 m2. Subjects were grouped by tertiles of eGFR level. PWVcf and AIx-75 increased ongoing from the top to the bottom eGFR tertile, while the values of PWVcr were comparable. Both univariate Pearson correlations and multiple stepwise regression analyses showed that eGFR significantly correlated to PWVcf, but not to PWVcr and AIx-75. Conclusions In Chinese women with normal to mildly impaired renal function, decreased eGFR affected carotid-to-femoral rather than carotid-to-radial stiffening. This provides rational to conduct future prospective studies to investigate predictors of atherosclerosis in this population.

Objective:To investigate the correlation between Helicobacter Pylori (HP) infection and abdominal obesity. Methods:A total of 1728 subjects who underwent routine health check-up and 13C or 14C urea breath test at the Health Management Center of Beijing Hospital from January 2018 to December 2018 were enrolled. The correlation between HP infection and metabolic syndrome (MS) components was analyzed. Results:There was no significant difference in HP infection rate between MS group and non-MS group [73.3%(360/491) vs. 68.7%(850/1 237), χ2=3.55, P=0.060]. The prevalence of abdominal obesity and elevated fasting blood glucose in HP positive subjects was significantly higher than that in HP negative subjects [71.7%(352/491) vs. 65.4%(809/1 237),χ2=6.36, P=0.042;80.7%(396/491) vs. 75.9%(939/1 237),χ2=4.50, P=0.034]. The non-obesity rate of HP positive subjects [28.1%(138/491)] was lower than that of HP negative subjects [34.3%(424/1 237), χ2=6.36, P=0.042). There were no significant differences in rates of hypertension, high triglyceride and low HDL-C, increased total cholesterol, increased LDL-C between HP-positive and HP-negative subjects (all P>0.05).There was no significant difference in HP positive rate between MS and non-MS groups [29.8%(360/1 210) vs. 25.3%(131/518), χ2=3.55, P=0.060]. The HP positive rate in subjects with abdominal obesity was higher than that with normal abdominal circumference [30.3%(352/1 161) vs. 24.5%(139/567), χ2=6.31, P=0.012], and the HP positive rate in subjects with elevated fasting blood glucose (FBG) was higher than that with normal FBG [29.7%(396/1 335) vs. 24.2%(95/393), χ2=4.50, P=0.034]. The HP infection rate was not associated with hypertension, hypertriglyceridemia and low HDL-C. Logistic regression analysis showed that abdominal obesity ( OR=1.327, P=0.016) was the risk factor of HP infection; and HP infection was the risk factor of abdominal obesity ( OR=1.277, P=0.043). Conclusion:HP infection is positively correlated with abdominal obesity and may be correlated with elevated fasting blood glucose, but not with other components of metabolic syndrome in health check-up population.

Methods Sixty male Sprague Dawley (SD) rats were divided into sham operation group, model group and fecal microbiota transplantation (FMT) group by random number table, each group 20 rats. The rat model of sepsis was established by injection of lipopolysaccharide (LPS) 10 mg/kg in tail vein. FMT group received nasogastric infusion of feces from healthy donor. Fecal samples were collected on the 6th day after the modeling to detect the levels of intestinal microbiota composition; the brain function was also evaluated by electroencephalogram (EEG), and the proportion of each waveform in EEG was calculated. After sacrifice of rats in different groups, the brain tissues were taken, the levels of protein expression and positive cells of Iba-1 in brain tissue were detected by Western Blot and immunohistochemistry method. Results ① Intestinal flora analysis showed that: the diversity index and Chaol index of the intestinal microbiota in model group were significantly lower than that in sham operation group (observed species:282±40 vs. 473±37, Chao1 index: 730±21 vs. 837±27, both P < 0.05); compared with the model group, the diversity index and Chaol index in FMT group were obviously higher (observed species: 461±20 vs. 282±40, Chao1 index:840±16 vs. 730±21, both P < 0.05).
