BACKGROUND: Fatal aortic rupture caused by esophageal foreign body (EFB), is associated with a high mortality, but can be prevented by thoracic endovascular aorta repair (TEVAR) that performed increasingly as technology improves. This study aims to investigate the cause, management and prognosis of suspected penetrating aortoesophageal foreign body injury. METHODS: Twelve cases who met the criteria were enrolled in this study. The demographic and clinical data were reviewed for evaluating the characteristics of EFB. RESULTS: Among 12 cases enrolled, 7 were males and 5 were females, with an age 27–86 years. The distance of EFB from aorta (DFA) of 7 cases were less than or equal to 0 mm, 5 cases were 0–2 mm. Eleven cases were managed with TEVAR, only one case was with open surgery standby but fi nally treated by fl exible endoscopy (FE) successfully, without TEVAR. In group with TEVAR, EFB of 7 cases were successfully removed by rigid endoscopy (RE), and one of them was failed at the first RE treatment. EFB of 2 cases were successfully removed by open surgery with TEVAR, and other 9 cases were managed by endoscopies with TEVAR. The mean length of stay of hospitalization (LOS) and length of ICU stay of patients treated by open surgery with TEVAR (18.50±2.12 days and 5.50±0.71 days) was signifi cantly longer than those of patients treated by endoscopy with TEVAR (7.00±2.74 days and 1.33±1.12 days, P<0.001 and P=0.001, respectively). Five cases had severe complications. CONCLUSION: Rational application of TEVAR can be a life-saving management for aortoesophageal foreign body injury, and jointed with endoscopy is safe and effective with a shorter length of ICU or total hospital stay.

Objective To simulate the process of hypoxic?ischemic brain injury at high altitude in a simulated cabin with plateau low pressure environment, and to prepare a rat model of cerebral injuries at different high altitudes. Method Thirty?two 0?day?old neonatal SD rats were divided into four groups, namely group A ( control group) and three test groups:group B (2000 m group), group C (4000 m group), and group D (6000 m group). The rats of control group were reared in a barrier environment. The rats of test groups were placed in a simulated cabin with plateau low pressure environment, and to prepare neonatal cerebral ischemia?hypoxia model by sport activities. The sport movements were carried out in the cabin in a swimming groove 60 min/d, and not less than 20 hours a day at high altitude low pressure environment. Zea Longa 5 point scale standard was used to determine the behavioral scores at the 3 th 7 th 11 th 15 th days, and samples were collected on the 15th day to observe red blood cell morphology using HE and 2, 3, 5?triphenyltetrazolium chloride ( TTC ) staining and ultrastructure by scanning electron microscopy. Result ( 1 ) The neurological scores of the test groups A, B, C were significantly different from that of the control group (P<0?05), and the scores of test group D and control group were very significantly different ( P <0?01 ) . ( 2 ) The histopathological examination using HE staining showed inflammatory cell infiltration in all rats of the test groups, and the extent of inflammatory cell infiltration was positively correlated with the increase of altitude. ( 3 ) The histopathology with TTC staining revealed prominent ischemia in the cerebral cortex of rats in the plateau hypoxic environment. ( 4 ) Scanning electron microscopy showed that the rat erythrocytes were cap?like in the group B, irregular in the group C, and zigzag shape in the group D. Conclusions In this study, a rat model of neonatal hypoxic?ischemic encephalopathy ( HIE) is successfully established by hypoxic cabin combined with sport activity. This model is stable, reliable, more closely mimicking the pathogenesis and clinical manifestation of neonatal HIE than models prepared with other methods, therefore, may be used in related research.

BACKGROUND:Titanium mesh is a new type of bone graft supports used for the treatment of spine, especial y the cervical spine disorders at home and abroad in recent years. But, at present, how to improve the cervical lordosis curvature during anterior surgery is the difficulty for the treatment of cervical spondylotic myelopathy.
OBJECTIVE:To observe the effect of straight titanium mesh and individual designed titanium mesh used in the bone graft fusion and internal fixation on the recovery of cervical curvature and Japanese Orthopaedic Association score during anterior cervical subtotal vertebrectomy in the patients with cervical spondylotic myelopathy.
METHODS:Forty-three patients with cervical spondylotic myelopathy treated with surgical indications of subtotal vertebrectomy and decompression internal fixation were included, and the patients were divided into two groups according to different internal fixation methods. There were 15 cases in the individual designed titanium mesh group and 28 cases in the straight titanium mesh group. The preoperative anteroposterior X-ray films of the cervical spine of al the patients were as the blank control group. The clinical data of the patients in two groups were retrospectively analyzed, and the postoperative Japanese Orthopaedic Association score, cervical curvature, intervertebral angles and intervertebral height were compared.
RESULTS AND CONCLUSION:The cervical lordosis angle and the intervertebral angle of surgery segment in the individual designed titanium mesh group were improved when compared with those in the straight titanium mesh group and the blank control group (P<0.01), and the straight titanium mesh group was better than the blank control group (P<0.05). The intervertebral height of surgery segment in the individual designed titanium mesh group and the straight titanium mesh group was increased for 3.69 mm and 3.22 mm respectively when compared with that in the blank control group, and there was significant difference between individual designed titanium mesh group and the straight titanium mesh group (P>0.05). There was no significant difference in Japanese Orthopaedic Association score between individual designed titanium mesh group and the straight titanium mesh group (P>0.05). During subtotal vertebrectomy for the treatment of cervical spondylotic myelopathy, cutting titanium mesh into trapezoidal shape to simulate the normal disc shape of former high to low can effectively restore the physiological curvature of cervical spine and the intervertebral height of surgery segment.

Percutaneous coronary intervention(PCI) can effectively restore reperfusion of ischemic myocardium in patients with coronary artery disease.But currently PCI treatment is just available for a small proportion of the patients with coronary artery disease,so there was an insufficiency of PCI in patients with coronary artery disease.From the perspective of ethics,the reasons for the phenomenon and some feasible strategies for the problem are also analyzed in this paper.

Objectives To study the correlations between stroke-preventive knowledge,health belief and health behaviors in community hypertensive patients.Methods The questionnaire of SPKQ,CHBMS and HPLPⅡwere used to take the investigation among 94 hypertensive patients from a community hospital in Guangzhou.Results The total score on SPKQ was 62.70±18.39 and the average scores on CHBMS and HPLPⅡwere 3.51±0.24 and 2.48±0.37,respectively.The stroke-preventive knowledge was positively correlated with health belief,health motivation and self-efficacy(r=0.289,P<0.01;r=0.246,P<0.05;r=0.350 (P<0.01,respectively).The health motivation was positively correlated with health behaviors(r=0.304,P<0.01)and the seriousness negatively correlated with health behaviors(r=-0.279,P<0.01).Conclusion Medical staff should provide much more stroke education with community hypertensive patients and promote patients’health motivation and self-efficacy of health belief in stroke prevention,help patients understand stroke seriousness,establish and sustain healthy lifestyles.

Objective:To investigate the effects of pre-existing antibody on seroconversion rate after influenza vaccination.Methods:This study recruited 1 900 healthy volunteers to receive influenza split vaccines in Xinjiang Uygur Autonomous region and Yunnan Province from September 2009 to October 2018. Hemagglutinin agglutination inhibition assay was used to detect the titers of specific antibodies in blood samples collected before vaccination and 28 d after vaccination and the effects of pre-existing antibody on the seroconversion to different influenza vaccine components were analyzed.Results:Trend analysis showed that with the increasing titer of pre-existing antibody, the seroconversion rates to A/H1N1, A/H3N2, B/Victoria and B/Yamagata vaccine components were gradually decreased (χ 2=121.76, P<0.001; χ 2=67.58, P<0.001; χ 2=45.25, P<0.001; χ 2=54.55, P<0.001). After adjusting for factors such as region, gender and age, multivariate logistic regression showed that pre-existing antibody titer equal to or higher than 40 was an independent factor that affected the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, and the adjusted OR (95%CI) values were 2.50(2.00-3.13)、1.64(1.35-2.00) and 2.50(1.79-3.45), respectively. Conclusions:The seroconversion rate to each vaccine component was negatively correlated with the pre-existing antibody titer. The factor that pre-existing antibody titer equal to or higher than 40 was detrimental to the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, but had no significant influence on B/Yamagata seroconversion.

OBJECTIVETo introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.

METHODSWe retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.

RESULTSThe time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.

CONCLUSIONSVaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.

Objective To study the predictive validity of fidgety general movement assessment in pre-term twins and multiplets for motor development outcomes.Methods A total of 53 pre-term twins or multiplets delivered between July 2011 and February 2016 participated in this study.They were assessed using a general movements (GM) assessment and participated in the follow-up program until one year old.The motor development outcomes of the infants at one year old were determined according to clinical diagnoses and the Peabody developmental motor scale number two (PDMS-2) evaluation.The predictive validity of fidgety general movement assessment for motor development outcomes was calculated against the standard motor development of infants at one year old.Results There were 53 twins or multiplets who accepted the GM assessment of fidgety movement period.Of these,43 were assessed as normal (NF) and ten (19％) as lacking a normal level of fidgety movement (F-).All 53 cases were followed-up for the motor development outcome.Forty-three cases (81.1％) were assessed as normal at one year old,while ten (18.9％) were assessed as abnormal.All ten had cerebral palsy,and no motor development retardation was found.The predictive value of F-for cerebral palsy was 90.0％ in terms of sensitivity,97.7％ in terms of specificity,90.0％ in positive predictive value,and 97.7％ in terms of negative predictive value.Conclusions Among pre-term twins or multiplets,the fidgety general movement assessment can be a useful early indicator of motor development difficulties.

Purpose To explore the value of Doppler ultrasound in the diagnosis of congenital hypertrophic pyloric stenosis (CHPS) by observing pylorus. Materials and Methods Sixyt-five children with CHPS diagnosed by ultrasound in Neonatology Department of Guangzhou First People's Hospital from 2006 to 2015 were retrospectively analyzed. CHPS group and 50 infants in control group were examined by Doppler ultrasound to observe the features of blood flow distribution and blood flow grading, and Doppler spectrum analysis was performed to observe contrast agent passing through pyloric canal. Results The difference of the thickness of muscular layer and mucous layer, and that of the long diameter and inner diameter of pyloric canal in CHPS group and control group all suggested marked statistical significance (P<0.01); the blood flow grading in muscular layer and mucous layer between the two groups showed statistical significance (t=13.33 and 18.77, all P<0.01). The blood flow velocity in muscular layer of CHPS group was (16.96±0.91) cm/s, resistance index (RI) 0.68±0.33, inner diameter of pyloric canal (1.98±0.33) mm. Conclusion Doppler ultrasound enables us to grasp the distribution and grading of blood flow of pylorus as well as the condition of contrast agent passing through pyloric canal, in which way the degree of pyloric stenosis can be evaluated by combining indexes such as Vmax and RI, and an objective basis for clinical choice of treatment can be provided, possessing high application value.
