Objective To investigate the value of detecting HEART score and HEARTS3 score in risk stratification and prognosis of acute coronary syndrome (ACS) in patients with non-ST segment elevation chest pain in emergency department (ED).Methods Clinical data of case-control retrospective study of 775 patients with non-ST segment elevation chest pain in ED were collected from July 2011 to March 2015.The patients were estimated and risk stratification was made with HEART score and HEARTS3 score.After follow-up visiting by telephone for 30 days,outcomes were found to be ACS and myocardial infarction (MI).And the patients were categorized with score into low,intermediate and high risk groups.The correlation between the ACS and risk score in three groups was analyzed.Comparison of capability of performance in predicting 30-day ACS between the HEART score and HEARTS3 risk score.Statistical analyses were performed using SPSS13.0.Enumeration variables were expressed as percentage.For comparison of predictive value of the two sets of scores,area under the receiver operating curve (auROC) was calculated and compared by Z test.Results There were 92 cases with 30-day ACS.The rate of ACS had a trend of increase with increase in HEART score and HEARTS3 score.The patients with higher scores of HEART and HEARTS3,higher incidence of ACS in 30 days.Especially,the high-risk patients with score≥7 of HEART score and≥8 of HEARTS3 score had higher rate of ACS.And there was significant difference in predicting high-risk patients between two sets of scoring (P ＜ 0.05).The HEARTS3 score outperformed the HEART score as determined by comparison of areas under the ROC curve for MI (0.952 vs 0.813;P =0.028),30-day ACS (0.913 vs.0.815;P =0.034).Conclusions HEART score and HEARTS3 score both can be used to evaluate and perform risk stratification for non-ST segment elevation chest pain patients in ED.But HEARTS3 score can more precisely stratify high-risk patients with chest pain for 30-day ACS.

Objective Neonatal lupus erythematosus (NLE) is an uncommon" passive autoimmune disease, which is associated with transplacental passage of maternal antibodies. It is often misdiagnosed as intrauterine infection or sepsis. The main purpose of this retrospective study was to summarize its clinical manifestations related with pathogenesis.Methods Data of all the NLE neonates, including clinical manifestations, immunochemical evidence of serum antinuclear antibodies (ANA), antibody to Ro/Sjogren's syndrome A ( anti-Ro/SSA), antibody to La/Sjogren' s syndrome B (anti-La/SSB) and anti-dsDNA antibodies in both infants and mothers, and images from head ultrasound and CT scans were analyzed. Follow-up was performed until one and half years of age or when all the clinical abnormalities had been resolved.Results Totally 8 cases (3 males and 5 females ) seen between September 2003 and February 2006 met the diagnostic criteria of NLE, in whom 4 were small for gestational age and one was born prematurely. Mean gestational age was (38.1 ± 1.9 ) weeks, mean birth weight (2605 ± 420) g, mean admission age (22.4 ± 27.7 ) days (2 hours-72 days) and mean age of onset (9.4 ± 12. 1)days (0-28 days). The common clinical manifestations included cutaneous lupus lesions (8 infants ), neural system abnormalities (2 infants ) and congenital heart block (2 infants). Annular, erythematous or desquamative lesions were seen in skin and all disappeared before 6 months of age. One patient presented with third degree atrio-ventricular block and was delivered by cesarean section because of " fetal distress" He did not recover by the end of one and half years follow-up. One infant was hypotonic with delayed neuro-motor development initially and during follow-up with both abnormal neonatal behavioral neurological assessment (NBNA) and imaging findings. Brain CT scan showed generalized low density involving periventricular and deep white matter at one week of age. At the age of one and a half years, he presented with normal mental development index determined by Child Development Center of China (CDCC) infant intelligence mensuration. Other abnormal clinical findings such as hepatosplenomegaly, anemia, thrombocytopenia, cholestasis and elevated liver enzyme activities were all resolved before 6 months of age. Only 3 mothers of the NLE infants were diagnosed as systemic lupus erythematosus (SLE) before parturition and only one received partial therapy. At least anti-Ro/SSA antibody or anti-La/SSB antibody or ANA was found in the affected patients. Seven cases had circulating anti-Ro and/or anti-La antibodies in the mothers and in the newborns, while ANA was positive in seven newborns and in all mothers. All the clinical symptoms disappeared before 18 months ot age except for congenital heart block. No special intervention was applied.Conclusions Serum auto-antibodies should be investigated to rule out NLE when a newborn infant has congenital heart block or rashes or thrombocytopenia, although there is no maternal history of SLE. Central nervous system abnormalities in NLE are likely to be a transient phenomenon and whether it will cause long-term sequelae is uncertain.

Objective To measure the in vitro antibacterial activity of tigecycline against carbapenems-resistant Acinetobacter calcoacetcus-Acinetobacter baumannii complex.Methods The isolated strains of carbapenems-resistant Acinetobacter calcoacetcus-Acinetobacter baumannii complex were collected in our hospital from December 2013 to February 2014.The MIC test strip was a-dopted to measure the MIC value of tigecycline.The break point adopted the judgment criteria published by FDA.Results All 61 strains of carbapenems-resistant Acinetobacter calcoacetcus-Acinetobacter baumannii complex had extremely high drug resistant rate to the commonly used antimicrobial agents.The sensitive rate of tigecycline was 80.3%,intermediation was 19.7% and no re-sistant strain was found in this study.MIC50 and MIC90 were 2 μg/mL and 3 μg/mL respectively.Conclusion Tigecycline has bet-ter in vitro antibacterial activity to the carbapenems-resistant Acinetobacter calcoacetcus-Acinetobacter baumannii complex isolated in our hospital.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.

Objective To discuss the experiences in successful treatment of hyperacute traumatic intracranial hematoma with percutaneous puncture and craniotomy.Methods Pereutaneous puncture and craniotomy was performed in 12 patients with hyperacute traumatic intracranial hematomas including seven with subdural hematoma,three with epidural hematoma and two with episubdural hematoma.Before operation,there found enlargement of bilateral pupil in six patients,enlargement of unilateral pupil in six and changed breathing rhythmicity in eight.Glasgow Coma Scale(GCS)was 3 points in four patients,4 points in six and 7 points in two.Results After pereutaneous puncture,enlarged pupil was retracted at different degrees in nine patients and spontaneous breathing conditions improved in seven.After crani otomy,two patients died within 24 hours,four died after 24 hours but six patients survived.The follow-up for 0.5-2 years showed four patients with sound Glasgow Outcome Score,two at vegetative state and six deaths.Conclusion Percutaneous puncture combined with craniotomy is an effective way for hyperacute intracranial hematoma.

In order to identify Peucedani Radix, Peucedani Decursivi Radix and their adulterants, the internal transcribed spacer 2 (ITS2) regions of Peucedani Radix, Peucedani Decursivi Radix and their adulterants were amplified and bidirectionally sequenced based on the Principles for Molecular Identification of Traditional Chinese Materia Medica Using DNA Barcoding, which has been promulgated by Chinese Pharmacopoeia Commission. Sequences were analyzed and assembled by Codon Code Aligner V3. 7.1. The relevant data were analyzed by MEGA 5. 0. Species identification analyses were performed by using the nearest distance methods and neighbor-joining (NJ) methods. The result showed that the ITS2 sequence lengths of Peucedani Radix were 229-230 bp and the average intra-specific genetic distances were 0.005. The ITS2 sequence lengths of Peucedani Decursivi Radix were 227 bp and the sequences contained no variation site. The average inter-specific K2P genetic distance of Peucedani Radix, Peucedani Decursivi Radix and their adulterants species were 0.044 and 0.065 respectively. The minimum inter-specific divergence is larger than the maximum intra-specific divergence of Peucedani Decursivi Radix. The nearest distance methods and NJ trees results indicated that Peucedani Radix, Peucedani Decursivi Radix and their adulterants species could be identification clearly. The ITS2 regions can stably and accurately distinguish Peucedani Radix, Peucedani Decursivi Radix and their adulterants.
