RESUMEN
@#Objective To describe the neuroelectrophysiological findings and genetic alteration of a patient with hereditary neuropathy with liability to pressure palsies (HNPP) who first presented with posterior interosseous nerve damage,and to improve clinicians'understanding of this disease. Methods We analyzed the clinical data of the patient and his families,and conducted a literature review on this disease. Results The 15-year-old male patient presented to the clinic complaining of weakness in the right forearm and inability to lift his fingers for more than one month. Electrophysiological examination demonstrated multiple peripheral nerve damage. Gene testing revealed large-fragment loss of heterozygosity in the exon region of the PMP22 gene. Conclusion HNPP is clinically heterogeneous,which should be considered when mild pressure can trigger nerve paralysis and electrophysiology indicates multiple peripheral nerve damage. Early diagnosis and symptomatic treatment can improve the quality of life and prognosis of the patients.
RESUMEN
Objective To observe the effect of CO2 pneumoperitoneum combined with position changes on the stability of cardiac electrophysiology in gynecological laparoscopy. Methods The gynecological laparoscopy was performed for 30 patients to undergo elective gynecological laparoscopy under general anesthesia ,with the pneumoperitoneum pressure of 12 mmHg and the Trendelenburg positionat 15° . The observations and analyses were done over the basic monitoring index and the QT interval (QT),T peak tend interval (Tp-e),heart rate corrected QT interval(QTc),QT dispersion(QTd),Tp-e/QT before anesthesia(T0),after anesthesia(T1),1 min after pneumoperitoneum (T2),30 min after pneumoperitoneum and head-down tilt (T3),30 min after deflation and supine position(T4). Results Compared with the time point of T0,QTd increased significantly at T1(P<0.05) and so it was with QT,QTc,QTd,Tp-e,Tp-e/QT at T2,T3,and T4(P<0.05). Compared with the time point of T2,QTc,QTd,Tp-e,Tp-e/QT significantly increased at T3(P < 0.05). Conclusions CO2 pneumoperitoneum combined with Trendelenburg position can prolong ventricular repolarization duration and destroy the stability of cardiac electrophysiology so it may increase the incidence of cardiovascular events.
RESUMEN
Objective:To investigate the effects of ginkgo biloba tablets plus relevant mechanism on HPA axis in patients with steroid-dependent asthma.Methods:80 patients with steroid-dependent asthma were divided into control group and experimental group at random,40 cases in every group.The control group were treated with pulmicort respules(1 mg/d) ,patients in the experiment group were given ginkgo biloba tablets in addition to routine treatment(120 mg/d).The therapeutic courses were both 12 weeks.The effective rate of reducing hormone,lung function,the plasma concentrations of ACTH and COR and the levels of PBMC GCR were deter mined before and after treatment.Results:The effective rate of reducing hormone was 89.47%in experimental group,which was 66.67%in control group.There were significant difference at the tows groups(P0.05).After treatment,the lung function, the levels of plasma concentrations of COR and the levels of PBMC GCR were increased significantly than control group( P<0.01,P<0.05),the levels of plasma concentrations of ACTH was decreased significantly than control group(P<0.01).There was a significant positive correlation between the value of FEV1/FVC and the plasma concentrations of COR,the levels of PBMC GCR( r=0.724,0.632, P<0.01).There was a significant negaitive correlation between the value of FEV1/FVC and the plasma concentrations of ACTH( r=-0.668,P<0.01).Conclusion:Ginkgo biloba tablets combined with routine treatment therapy can increase the effective rate of reducing hormone in patients with steroid-dependent asthma,which can improve the lung function maybe by regulate the HPA axis and upgrade the levels of GCR.
