ObjectiveTo observe effects of ginkgo bilobate extract injection on the hemorheology,blood lipid and c-reactive protein in serum of patients with cerebral infarction. Methods62 cases patients with cerebral infarction were randomly divided into two groups by means of random number table. Two groups were both given routine treatment. The control group was treated with 20ml compound salvia injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days, and the treatment group was treated with 20ml ginkgo bilobate extract injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days. The clinical symptoms were observed, hemorheology related index, level of blood lipid and c-reactive protein were detected before and after the treatment. ResultsCompared with the control group,hemorheology related index decreased significantly in the treatment group, especially whole blood viscosity ( 1.57±0.28) mpa ·s (P＜0.01). Blood reduced viscosity (13.95 ± 2.07) mpa ·s, erythrocyte aggregation index (1.37±0.12) , hematocrit (42.36±8.16) were also decreased significantly (P＜0.05) .Triglyceride (TG)(1.23±0.12) mmol/L、 cholesterol (TC) (4.29±1.17) mmtmol/L、 low density lipoprotein cholesterol (LDIL-C)(2.31± 0.39) mmol/L and c-reactive protein ( 10.48 ±- 3.82) mg/L in serum in the treatment group were lower than those of the control group (P＜0.01 orP＜0.05) , high density lipoprotein cholesterol (HDL-C) ( 1.78±0.76) mmol/L in serum was higher than that of the control group (P＜0.01) .The total effective rate of the treatment group and the control group was 87.1％ and 67.7％ respectively, there was a significant difference (x2=3.553, P＜0.05). Conclusion The ginkgo bilobate extract injection can protect cerebral infarction from injury,which may be related with its action on regulating the blood viscosity and level of blood lipid.

Objective To investigate the gender differences of glucose metabolic network in brains of healthy adults at resting state by 18F-FDG PET.Methods A total of 204 dextromanual,healthy individuals (104 males,average age:(53.45±11.51) years;100 females,average age:(54.11±12.09) years) were enrolled from June 2011 to June 2016 to construct brain metabolic networks.The nodal and global parameters,including clustering coefficient (Cp),characteristic path length (Lp) and betweenness centrality (Cb),were analyzed by graph theory.Permutation test with 1 000 repetitions was used.Results The brain metabolic networks derived from 18F-FDG PET data were with small-world properties in both male group and female group.Compared with Cb in females,Cb in males was significantly reduced in left postcentral gyrus,right angular gyrus and left temporal pole/middle temporal gyrus (permutation test,all P<0.05);and it was increased in left amygdala,left precuneus,right temporal pole/middle temporal gyrus and left inferior temporal gyrus (permutation test,all P<0.05).Comparing with the females,the male group had higher Cp and longer absolute Lp but without significant difference (permutation test,all P>0.05).Conclusions There are gender-related differences of topological structure in whole-brain metabolic networks.Gender should be considered as a covariate while designing experiments,accounting for cerebral metabolic data from normal control and experimental patients as well as making clinical decisions.

Objective:To observe the effects of alprostadil at different doses on C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in patients with angina pectoris.Methods:From August 2017 to April 2018, 120 patients with angina pectoris admitted to China Coast Guard Hospital of the People's Armed Police Force were selected and divided into control group (60 cases) and observation group (60 cases) by random number table method.Both two groups received routine anti-angina treatment, while the control group received 10 μg alprostadil, the observation group received 20 μg alprostadil for 2 weeks.The changes of CRP, TNF-α, IL-6 and hemorheological indicators before and after treatment were compared between the two groups.Results:Before treatment, there were no statistically significant differences in the CRP, TNF-α and IL-6 between the two groups (all P>0.05). After treatment, the CRP, TNF-α and IL-6 levels in the observation group were (4.63±0.62)mg/L, (0.46±0.08)μg/L, (46.59±4.72)ng/L, respectively, which were significantly lower than those in the control group [(6.18±0.74)mg/L, (1.19±0.28)μg/L, (58.62±5.07)ng/L]( t=12.437, 19.418, 13.452, all P<0.05). The high shear viscosity, low shear viscosity, plasma viscosity and platelet aggregation rates in the observation group were (4.27±0.46)mPa/s, (8.07±0.18)mPa/s, (1.03±0.25)mPa/s, (37.42±1.05)%, respectively, which were lower than those in the control group [(5.14±0.588)mPa/s, (10.43±0.42)mPa/s, (2.01±0.46)mPa/s, (40.19±1.86)%] ( t=9.103, 40.006, 14.499, 10.046, all P<0.05). Conclusion:The conventional dose of alprostadil (20 μg) is effective in the treatment of angina pectoris.It can improve CRP, TNF-α, IL-6 and hemorheological parameters of patients.

Objective:To observe the efficacy of meglumine adenosine cyclophosphate (MAC) in the adjuvant treatment of chronic congestive heart failure(CHF) in the elderly, and its effects on cystatin C(Cys-C) and plasma B-type natriuretic peptide(BNP).Methods:From August 2017 to August 2018, 110 elderly patients with chronic CHF admitted to Zhejiang Provincial Armed Police Corps Hospital were selected and randomly divided into control group(55 cases) and observation group(55 cases) by random number table method.The control group was treated with routine treatment, while the observation group was treated with MAC on the basis of routine treatment.Both two groups were treated for 2 weeks.The clinical efficacy, left ventricular ejection fraction (LVEF), cardiac output, Cys-C and plasma BNP were compared between the two groups.Results:The total improvement rate of the observation group was 94.55%(52/55), which was higher than 78.18%(43/55) of the control group, the difference was statistically significant(χ 2=6.253, P<0.05). Before treatment, there were no statistically significant differences in LVEF, cardiac output, BNP and Cys-C between the two groups(all P>0.05). After treatment, the LVEF[(44.16±6.82)%], cardiac output[(8.07±1.45)L/min] of the observation group were significantly higher than those of the control group[(40.71±5.38)%, (6.44±1.37)L/min], and BNP[(1.65±0.24)mg/L], Cys-C[(552.79±10.46)mg/L] of the observation group were significantly lower than those of the control group[(2.31±0.48)mg/L, (681.73±12.71)mg/L], the differences were statistically significant( t=2.945, 6.060, 9.121, 0.551, all P<0.05).

Objective To evaluate the efficacy and safety of selective brain hypothermia (SBH) in the treatment of neonates with moderate or severe neonatal hypoxic-ischemic encephalopathy (HIE), and the effect of SBH treatment on serum levels of neuron-specific enolase (NSE) and central nervous specific protein S100. Methods A prospective randomized controlled trial was conducted. From January 2015 to June 2017, 42 children with moderate to severe HIE in the neonatal intensive care unit (NICU) of the First Affiliated Hospital of Bengbu Medical College were enrolled, and they were randomly divided into SBH treatment group and routine treatment group after obtaining the consent of the guardian of the children. The children in routine treatment group were given the traditional symptomatic supportive treatment, supplemented by drugs to promote nerve cell growth. On the basis of traditional treatment, the children in the SBH treatment group were given SBH treatment within 6 hours after birth. The nasopharyngeal temperature was maintained at 33.0-34.5 ℃ and the rectal temperature was maintained at 34.5-35.0 ℃. The general clinical data of the two groups including gender, gestational age, birth weight, age, 5-minute neonatal asphyxia score (Apgar score), score for neonatal acute physiology perinatal extension version Ⅱ (SNAPPEⅡ) were collected. The primary outcomes were hospitalized death, severe disability at 15 months of age, neonatal behavioral neurological assessment (NBNA) score at 28 days of age, and Bayley scales of infant development (BSID) score [including mental development index (MDI) score and psychomotor development index (PDI) score] at 15 months of age at follow-up. The secondary outcomes were serum levels of NSE and S100 protein. The occurrences of adverse events in the two groups were recorded. Results Among 42 HIE children, 1 child of severe congenital malformation and 1 child of platelet count (PLT)﹤50×109/L were excluded, and 40 children were enrolled in the study group. During the follow-up period, 2 children of SBH treatment group and 2 children of routine treatment group were lost or the outcome was unknown. Finally, 18 children of each group were enrolled in the analysis. There was no significant difference in the baseline data of gender, gestational age, birth weight, age, 5-minure Apgar score or SNAPPEⅡ score between the two groups, indicating that the baseline data of the two groups were balanced and comparable. The incidence of severe disability in the SBH treatment group was significantly lower than that in the routine treatment group [5.6% (1/18) vs. 44.4% (8/18), P﹤0.05]. There was 1 child death in the routine treatment group and no death in the SBH treatment group. Compared with the routine treatment group, the 28-day NBNA score of the SBH treatment group was increased by 2.9 [95% confidence interval (95%CI) = 1.0-4.8], BSID score at 15 months of age was improved significantly, MDI score was increased by 11.8 (95%CI = 4.3-19.3), and PDI score was increased by 12.4 (95%CI = 2.5-22.3), with significant differences between the two groups (all P﹤0.05). After 3 days of treatment, the serum NSE and S100 protein levels in both groups were significantly decreased as compared with those before treatment [NSE (μg/L): 30.15±15.18 vs. 31.32±14.75, S100 (ng/L): 387.5 (273.3, 573.0) vs. 890.0 (590.5, 1 162.5) in routine treatment group; NSE (μg/L): 29.09±16.22 vs. 32.25±15.43, S100 (ng/L): 402.5 (302.2, 580.5) vs. 842.0 (462.3, 1 200.5) in SBH treatment group, all P﹤0.05]. There was no significant difference in serum NSE or S100 protein level between the two groups (all P﹥0.05). There was no serious adverse event such as arrhythmia, large vein thrombosis or irreducible hypotension in both groups, and there was no significant difference in the incidence of general adverse events such as sinus bradycardia, scleredema, blood glucose disorder, or systemic infection between the two groups [16.7% (3/18) vs. 11.1% (2/18), 5.6% (1/18) vs. 5.6% (1/18), 22.2% (4/18) vs. 11.1% (2/18), 5.6% (1/18) vs. 5.6% (1/18), all P﹥0.05]. Conclusions SBH treatment could significantly increase the NBNA score at 28 days of birth and BSID score at 15 months of age, reduce the incidence of severe disability in moderate and severe HIE children, but it was not be proved that SBH could reduce the mortality. Compared with routine treatment, SBH treatment had no significant superiority on improving the levels of serum NSE and S100 protein, suggesting that SBH could not protect the brain by inhibiting the apoptosis of nerve cells and promoting the repair of nerve cells.

The quality of Paeoniae Radix Alba and Paeoniae Radix Rubra is evaluated by root thickness, and paeoniflorin serves as a common quality indicator of them. However, the correlation between the content of bioactive compounds and the root size is still unclear. Therefore, this study characterized the distribution patterns and content of seven bioactive compounds including paeoniflorin in different tissues of Paeonia lactiflora roots, analyzed the correlation between the root size and the content of bioactive compounds based on the xylem-to-bark ratio, and further determined the index components for quality assessment. Nine samples of fresh P. lactiflora roots were collected from the genuine cultivation area. The distribution of bioactive compounds in different tissues on the cross-section of the root was firstly analyzed by desorption electrospray ionization-mass spectrometry imaging(DESI-MSI). Subsequently, the content of bioactive compounds was determined in the xylems and barks of the roots by UPLC. The compounds with the largest difference between the xylem and the bark were selected by orthogonal partial least squares discriminant analysis(OPLS-DA). The results indicated that paeoniflorin, benzoylpaeoniflorin, oxypaeoniflorin, gallic acid, and 1,2,3,4,6-pentagalloylglucose were significantly accumulated in the xylems, while albiflorin and catechin were mainly distributed in the barks. Paeoniflorin and albiflorin, with the largest differences in the xylem and the bark, had the highest content in the two tissues. The root diameter was positively correlated with paeoniflorin content and negatively correlated with albiflorin content. As isomers with different efficacies, paeoniflorin or albiflorin can be chosen as the quality marker corresponding to specific clinical application to launch quality classification evaluation of multi-functional Chinese medicines.
