Relevant factors of type 2 diabetic patients with cerebral infarction / 中华临床营养杂志

Objective To investigate the relevant factors of type 2 diabetes mellitus (T2DM) with cerebral infarction (CI).Methods A total of 323 patients with T2DM from February 2012 to March 2017 in Inner Mongolia medical university affiliated hospital were included in this study.150 patients with T2DM and CI were considered as experiment group,173 cases of T2DM without CI were considered as control group.The clinical data of two groups were analyzed.Results The history of diabetes,smoking and hypertension were longer in experiment group than in control group (P＜ 0.05).The patients in experiment group had higher fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total triglycerides (TG),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),non-HDL-C,homocysteine (Hcy),fibrinogen (FIB),retinol binding protein 4 (RBP4) and lower HDL-C,apolipoprotein A1 (ApoA1) than the patients in control group (P＜ 0.05).Multiple-factor logistic regression analysis showed that long-term smoking,long history of hypertension,high TG,high LDL-C,high non-HDL-C,high Hcy,high RBP4,low HDL-C and low ApoA1 were risk factors for CI in patients with T2DM (P＜0.05).After adjusting common variables (diabetes history,hypertension history,smoking history,HbA1c,TG,TC),multiple-factor logistic regression analysis showed that LDL-C,non-HDL-C,Hcy,RBP4 were risk factors for CI in T2DM (P＜0.05).HDL-C and ApoA1 were protective factors for CI in T2DM (P＜0.05).Conclusion The risk factors for CI in patients with T2DM include long-term smoking,long hypertension history,high HbA1c,high TG,high LDL-C,high non-HDL-C,high Hcy,high RBP4,low HDL-C and low ApoA1.Patients should be advised to quit smoking,control blood glucose and blood pressure,and regulate blood lipid levels.

Effects of Ringer's solution with different concentrations of alcohol on biphasic compound action potentials of frog sciatic nerve trunk / 中国应用生理学杂志

OBJECTIVE@#To quantitatively investigate the effects of Ringer's solution with different concentrations of alcohol (1%～80%) on biphasic compound action potentials (AP) from frog sciatic nerve trunk, and their recoveries from alcohol effects.@*METHODS@#Individual segments of frog sciatic nerve trunk with a length of 6 to 8 cm were prepared. Ringer's solution with different concentrations of alcohol (0%, 1%, 2%, 4%, 8%, 16%, 32%, 48%, 64% and 80%) was applied onto the segment of the trunk between the stimulus and ground electrodes via an agent reservoir which was newly armed in a nerve trunk shielded chamber for 5 minutes. The nerve trunk was respectively electro-stimulated to generate the biphasic compound AP which was recorded using the experimental system of BL-420F. This was followed by 5 times washout plus 5 min administration with Ringer's solution before recovery recording of AP.@*RESULTS@#Compared to normal Ringer's solution, Ringer's solution with alcohol at ≤4% did not have dramatic impacts on the AP amplitude and conduction velocity, while Ringer's solution with alcohol at ≥8% there was significant decrease in these two parameters. Ringer's solution with alcohol at the conentrations of 16%, 32% and ≥48% could prevent a small proportion (30%), a large proportion (90%) and all (100%) of sciatic nerve trunks, respectively, from generating AP. Washout with normal Ringer's solution after alcohol application at the concentration of ≤32%, AP could totally recover to normal status. While alcohol at the concentration of 48%, 64% and 80%, the probabilities to regenerate APs were 90%, 40% and 0%, and the AP amplitudes were decreased to 60%, 36% and 0%, respectively. After washout, AP conduction velocity showed no difference with alcohol at the concentration of ≤8% when compared with that before washout, while it could not be recovered to normal under alcohol at ≥16%.@*CONCLUSION@#Ringer's solution with different concentrations of alcohol exerts different effects on biphasic compound AP amplitude and conduction velocity. Hopefully, our findings could be helpful for the alcoholic usage and its recovery from alcoholic damage.

Changes of Cytokines Measurement in Serum and Cerebrospinal Fluid in Asphyxia Ne onates and Its Relationship with Prognostic / 实用儿科临床杂志

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.

Study on Mechanism of Hyperoxia Through Mechanical Ventilation Induced Lung Injury in Newborn Rabbit / 实用儿科临床杂志

Objective To explore the effect of hyperoxia through mechanical ventilation induced lung injury(VILI) in newborn rabbit.Methods One hundred newborn rabbits aged 1-5 days were randomly divided into 4 groups: with 900 mL/L O2 and mechanical ventilation(MV),group A received high peak inspiratory pressure(HPIP),group B received moderate peak inspiratory pressure(MPIP),group C received low peak inspiratory pressure(LPIP),and group D with no mechanical ventilation with room air.There were 30 rabbits in group A,B,C,10 rabbits in D group.All rabbits were killed at 1,3,6 h after trial respectively.Wet-to-dry weight ratio(W/D) of left lung,and white blood cell(WBC)counts in broncho alveolar lavage fluid(BALF) were measured.The changes of lung histopathology were assessed by hematoxylin-eosin(HE) staining and observed under light microscope.Results Compared with group B and C,the group A demonstrated more pulmonary hemorrhage and pulmonary bullae formation,and the WBC and neutrophils counts in BALF increased and the W/D was higher compared with group B and group C.Meanwhile,alveolar epithelial cellⅡ(AECⅡ) hyperplasy transformed to AECⅠ.In group C,AECⅡswelled and lung tissue edema showed obviously,after 6 hours collagen fibers hyperplasia appeared.Part pulmonary atelectasis was obvious in group C.Conclusions HPIP ventilation can increase lung injury induced by hyperoxia in newborn rabbits,but has minimal effects on MPIP and LPIP ventilation.Pulmonary histopathologic changes participate in the newborn rabbit machine ventilation induced lung injury.
