RESUMO
Objective@#To investigate the clinical characteristics of diabetic patients combined with acute myocardial infarction (AMI) and to compare the prognosis between diabetic and non- diabetic patients in 4-5 years after the onset of AMI.@*Methods@#Followed the certain inclusive and exclusive criteria, a total of 420 patients with acute myocardial infarction were included and divided into diabetes group (group D) and non-diabetes group (group N) with numbers as 161 people and 259 respectively. Baseline data, clinical information, short-term outcome and long-term prognosis of the two groups were compared and analyzed.@*Results@#Among the patients with diabetes, the average age was older (65.65±11.33 vs. 63.30±15.34), with fewer males (64.59% vs. 79.92%); and more likely to have other complications as hypertension (64.60% vs. 53.28%) or hyperlipidemia (42.24% vs. 26.25%). 59.29% of the patients in group D showed pathological changes in 3 major coronary arteries, which were significantly more than its counterpart (40.83%). The proportion of patients that had undergone the coronary artery bypass, grafting (11.11% vs. 5.31%) appeared also higher. There was no significant difference seen in the short-term outcomes between the two groups, but results from the long-term follow-up program showed that both the incidence of Major Adverse Cardiovascular Events (MACE) (50.67% vs. 27.72%) and the all-cause mortality (20.00% vs. 9.90%) in group D were higher than those appeared in group N (27.72%).@*Conclusions@#Patients suffered from the combination of both diabetes and acute myocardial infarction appeared older in age, more in females, with more complications and the coronary artery lesions were more severe and wider. During hospitalization, no significant difference was seen regarding the short-term outcomes between the two groups but the results from long-term follow-up process showing that the risk of MACE events was significantly higher in patients with type2 diabetes.
RESUMO
To explore the magnetic resonance imaging (MRI) characteristics of glioma with Brg/Brm-associated factor 53a (BAF53a) expression. Methods: A total of 121 patients with glioma was divided into a BAF53a high expression group (n=79) and a low expression group (n=42) according to the results of immunohistochemistry. Then the MRI characteristics, including lesion location, number, boundary, maximum diameter, peripheral edema, midline structure shift, homogeneity, cystic necrosis, hemorrhage, strengthening degree, ependymal strengthening, pia mater enhancement, deep white matter invasion and lesion across the midline (total 14 items), were analyzed. Results: The results showed that there were significance difference in lesion border, lesion edema, enhancement of the lesion, and deep white matter invasion between the 2 groups (all P<0.05). Conclusion: The MRI characteristics, such as lesion border, lesion edema degree, enhancement degree of the lesion and deep white matter invasion, might be associated with BAF53a expression in gliomas.

Objective:To investigate the value of proton magnetic resonance spectroscopy (1H-MRS) on the diagnosis of SCA3/MJD,and to calculate the correlation between 1H-MRS ratio and the clinical score.Methods:Sixteen patients with SCA3/MJD and 19 healthy volunteers were scanned with 1H-MRS.The data of N-acetyl aspartate,creatine,choline-containing compounds,myoinositol,NAA/Cr,Cho/Cr,and mI/Cr ratio were collected,which were grouped for comparative study.The onset patients with SCA3/MJD were evaluated with the International Cooperative Ataxia Rating Scale and Scale for the Assessment and Rating of Ataxia,the correlation between NAA/Cr,Cho/Cr or mI/Cr ratio and the clinical score was calculated.Results:The NAA/Cr in the pons and cerebellar dentate nucleus from the onset patients with SCA3/MJD was significantly reduced compared to that in the normal control group.The NAA/Cr in the cerebellar dentate nucleus of onset patients with SCA3/MJD was obviously correlated with ICARS.Conclusion:SCA3/MJD lesions are mainly located in the cerebellum and brainstem,where gray and white mater are also involved.The cerebellar dentate nucleus may be the earliest involved area.There is a correlation between the ICARS and the cerebellar lesion degree.The ICARS reflects the severity of clinical manifestations.1H-MRS is useful in the diagnosis of SCA3/MJD.
RESUMO
Objective To explore the effect of lidocaine, the sodium channel blocker, on electrical physiological changes in the circumstances of hypoxia. Methods The effects of different doses of lidocaine (10~ -5 mol/L, 10~ -4 mol/L and 5?10~ -4 mol/L) on the changes in voltage-dependent sodium currents in hippocampal neurons of the rat induced by 10~ -5 mol/L DNP (2,4-dinitrophenol) were recorded by whole-cell configuration of the patch clamp. Results DNP could increase the spike amplitude of sodium currents significantly. With the application of 10~ -5 mol/L and 10~ -4 mol/L lidocaine in advance, the spike values of each group were not significantly different from that of the contral after the administration of DNP, but the spike values after 5?10~ -4 mol/L lidocaine were lower than that of the control after the administration of DNP. Conclusion With the use of DNP, lidocaine can achieve the effect of brain protection through inhibiting the voltage-dependent sodium channel.

Objective To investigate the influence of balanced anesthesia(BA)versus total intravenous anesthesia(TIVA)on the hemodynamics and respiratory function of patients undergoing laparoscopic hysterectomy.Methods Two groups of patients undergoing elected laparoscopic hysterectomy received balanced anesthesia(BA group,20 cases)or total intravenous anesthesia(TIVA group,20 cases)respectively.Data of hemodynamics and respiratory system were recorded and the compliance of respiratory system was calculated.Results The MAP at 10 minutes after pneumoperitoneum(PP)was elevated significantly than that before-induction in BA group(P
RESUMO
Objective To investigate the effectiveness and safety of applying compound lidocaine cream on tracheal mucosa as topical anesthesia to reduce the stress reaction during extubation of tracheal tube. Methods Sixty patients (aged 18-65yr,body weight 40-80kg,ASA Ⅰ-Ⅱ) scheduled for elective surgery under general anesthesia were selected,and they were randomly divided into compound lidocaine cream group (group L,n=30) and control group (group C,n=30). Orotracheal intubation was performed in all the patients. Compound lidocaine cream was uniformly smeared on the foremost third of endotracheal tubes before intubation in group L,and no drug was coated on endotracheal tubes in group C. The changes in blood pressure and heart rates during extubation,the use of hypotensive drugs,cough reflex,breath holding,sore throat and pharyngeal discomfort after extubation were compared between the two groups. Results The operation and intubation time of the two groups showed no significant difference. The blood pressure and heart rate during extubation,the rate of using hypotensive drugs,and the incidence of cough reflex and breath holding were lower in group L than in group C,while the foreign body sensation in pharynx were after extubation was more frequent in group L than in group C. The incidence of pharyngodynia was similar in the two groups,and the pharyngodynia and foreign body sensation in pharynx markedly improved one day after operation in both groups. Conclusion Topical anesthesia of tracheal mucosa using compound lidocaine cream may reduce the cough reflex and breath holding during extubation,and inhibit the stress reaction.
