OBJECTIVETo explore the alterations of after depolarization and triggered activity in myocardiac muscle during progression of mouse aortic stenosis.

METHODSAfter the establishment of mouse aortic stenosis model, the heart was collected and intracellular potential was recorded using standard glass microelectrode. After the recording, the action potential (AP), early after depolarization (EAD), delayed after depolarization (DAD) in papillary muscles were analysed.

RESULTS(1) Compared with that of time-matched control mice, there were no changes of the action potoutial duration at 90% repolarization(APD90) in model mice at 2 and 5 weeks, whereas the APD90 was progressively prolonged at 9 and 13 weeks. (2) During the 30 minites of the experiment, spontaneous EADs and DADs were frequently present in medel mice at 9 and 13 weeks, were not in control and model mice at 2 and 5 weeks. (3) Compared with those of control group, EADs and DADs triggered by hypokalaemia or isoproterenol were increased significantly. The incidence rate of triggering EADs and DADs was progressively increased over time.

CONCLUSIONEAD, DAD and trigger activities increase gradually during the process of aortic stenosis, and it suggests that the myocardium electrical-instability is markedly increased in the insult hearts.

OBJECTIVETo find the characteristic parameters from electrocardiogram (ECG) which is most related to pathological progress, surface ECG was performed in mice at 2, 5, 9 and 13 week post surgery.

METHODSElectrocardiogram recordings: The mice were anaesthetized with tribromoethanol (250 mg/kg, i.p.). Lead II surface ECG were acquired by using the Biopac System MP150 at a rate of 5 kHz.

RESULTS(1) No arrhythmia was observed in Sham and 2-week Band mice. Spontaneous arrhythmias were observed in ECG recordings, with an incidence of 15%, 28% and 63% in 5-, 9- and 13-week Band mice, respectively. Tachyarrhythmias, such as frequent premature ventricular extrasystole, bigeminy, trigeminy, and paroxysmal tachycardia were found. (2) Analysis of ECG recordings revealed a significant prolongation of QT and QTc intervals. Compared with age-matched Sham mice, the increment in QT and QTc intervals was 20.4%, 32.7%, 49.7%, 61.0% and 27.1%, 32.1%, 43.9%, 59.1% at 2, 5, 9 and 13 week, respectively (P < 0.01). (3) The characteristic change in electrocardiogram was on the J wave. The amplitude of J wave was upward in Sham mice, and it was significantly flattened or inverted in Band mice. (4) Except that RR interval at 2 week showed a slight decrease, there was no significant change in PR interval and RR interval in Band mice.

CONCLUSIONIn the present study, we found that the increase incidence of spontaneous arrhythmias, prologation of QT interval and changes in the amplitude of the J wave in the surface ECG during progression of mouse cardiac hypertrophy and failure, and the progressive pattern indicated that a gradual aggravation of the ventricular repolarization delay in this mouse model.

OBJECTIVETo observe the effect of electroacupuncture (EA) combined with ultraviolet therapy on herpes zoster at the acute stage and the impacts on serum interleukin 2 (IL-2), interleukin 6 (IL-6) and interleukin 10 (IL-10) in the patients.

METHODSThirty-four patients of herpes zoster were randomized into a medicine group and a combined therapy group, 17 cases in each one. In the medicine group, the intravenous drops with acyclovir injection, muscular injection with cobamamide and the topical with acyclovir ointment were applied. Additionally, TDP was radiated locally. In the combined therapy group, on the basis of the treatment as the medicine group, EA and ultraviolet therapy were supplemented. The duration of treatment was 10 days in the two groups. Before and after treatment, blister relief, incrustation time and the visible analogue scale (VAS) were recorded in the two groups. The clinical efficacy was assessed in the two groups and the levels of serum IL-2, IL-6 and IL-10 were determined in the two groups.

RESULTSIn the combined therapy group, the time of blister relief and incrustation was earlier apparently than that in the medicine group (both P<0.05). VAS score after treatment were reduced as compared with that before treatment in the two groups (both P<0.01), and the reducing amplitude in the combined therapy group was larger than that in the medicine group (P<0.01). The total effective rate was 94. 1% (16/17) in the combined therapy group, higher than 76.4% (13/17) in the medicine group (P<0.05). After treatment, IL-2 levels were increased as compared with those before treatment in the two groups (both P<0.05), the levels of IL-6 and IL-10 were reduced obviously as compared with those before treatment in the two groups (all P<0.01). After treatment, the levels of IL-6, IL-10 were reduced much more apparently in the combined therapy group as compared with those in the medicine group (both P<0.05).

CONCLUSIONEA combined with ultraviolet irradiation more rapidly and effectively relief the symptoms of herpes zoster, significantly relief pain, shorten the duration of sickness, improve the body immunity and reduce nerve injury.

OBJECTIVE:To evaluate evidence foundation of phamracogenetics personalized medication,and to provide refer-ence for clinical application. METHODS:Using“phamracogenetics”“pharmacogenomics”and“gene polymorphism”as key words,related literatures and clinical guideline were retrieved from PubMed,CNKI,Wanfang database,and analyzed in respects of involved gene,site and drug types,etc. Evidences of package inserts of phamracogenetics biomarker were evaluated by using phamracogenetics practice and prevention evaluation guideline. RESULTS:8 276 papers,25 guidelines and 166 drug package in-serts are available for analysis. The phamracogenetics literatures mostly focus on the relationship between some one gene and differ-ent drugs. In guidelines,some one specific gene can guide clinical application of multiple drugs in different fields. In drug package inserts,general level of clinical evidence is not high;detectable biomarkers is inadequate in category,and detection rate is only 38.06% besides targeting preparation. CONCLUSIONS:Under the condition of low clinical evidence level the detection of pharma-cogenetics biomarker should be conducted carefully,and basic study should be further strengthened.

OBJECTIVE: To analyze the general and forensic pathological characteristics of death due to fat embolism syndrome (FES) and to provide reference data for forensic identification. METHODS: Twenty autopsy cases due to FES were selected from the forensic center of a medical college from 1999 to 2012. The general and forensic pathological characteristics such as the ways and types of injuries, clinical manifestation and the pathological changes were summarized. RESULTS: Fat embolism mainly occurred after long bone fracture or a large area of soft tissue injury with the majority of cases being fat embolism of lung and occasional cases being combined embolisms of lung and brain as well. The onset of symptoms appeared shortly after the injury or surgery. Lipid droplets could be observed within small pulmonary vessels and verified by special staining. CONCLUSION There are particular characteristics in death due to FES in concern with types of injuries, onset of symptoms and pathological findings. In order to find out the direct evidence of FES, special staining (oil red O staining) can be used in the forensic identification.
