ObjectiveTo investigate the clinical features of intramedullary spinal cord tumors(IMSCT) in children.MethodsThe clinical data including sex,age,pathohistology,clinical manifestations and medical check-up collected from 16 children diagnosed as IMSCT in Shengjing Hospital Affiliated to China Medical University,were retrospectively reviewed and analyzed.ResultsThe study subjects inclu-ded 11 male and 5 female,with an average age of(8.55?4.28) years old,ranged from 15 months to 14 years old.The interval lasted 1 day to 9 years from onset of the syndrome to confirmed diagnosis of IMSCT.The first clinical manifestation was mostly pain.The main clinical mani-festations included limb dyskinesia in 14 cases,pain in 12 cases,urine and stool disturbance in 9 cases,gait irregularity in 8 cases,extremity atrophy in 3 cases.Medical check-up included abnormal tendon reflex in 14 cases,abnormal superficial reflex in 9 cases,sphincter dilatation in 6 cases,positive Babinski's signs in 5 cases,spinal deformity in 4 cases,region masses in 3 cases,paraesthesia in 2 cases,inequality of lower limb in 1 case,dermai sinus in 1 case,pigmentation in 1 case.The cases were evaluated by magnetic resonance imaging,which presented thickened spinal cord and intramedullary abnormal signals in all the cases.Pathological types: teratoma in 5 cases,dermoid cysts in 2 cases,epidermoid cyst in 2 cases.Misdiagnoses included urinary tract infections in 2 cases,rheumatoid arthritis in 1 case,and lumbar disc protrusion in 1 case.ConclusionsThe main pathohistology of pediatric IMSCT is congenital tumor.First clinical manifestation is pain.MRI can show a reliable evidence for the diagnosis.It is important to improve the outcomes of pediatric IMSCT by establishing the diagnosis and administering proper management as early as possible.

Excimer laser was found in 1975, and has been used in corneal refractive surgery, which made a great progress and become rapidly developed. ArF laser of 193 nm has high accuracy because it can gasify corneal tissue molecule. Moreover, it does not produce heat effect on tissues surrounding irradiated sites, so not produce adverse effect on corneal structure. At present, excimer laser has been successfully used in corneal radial incision, excimer laser corneal refractive surgery, laser in situ keratomileusis, laser epithelial keratomileusis and laser subepithelial keratomileusis. With increasing understanding of excimer laser and accumulating clinical experience, novel, accurate and predictive excimer laser corneal refractive surgery will be developed.

Point-of-care testing technology has been widely used in clinical practice, especially in the emergency department of intensive care unit, operating room, and so on.Clinicians should correctly select patients, standardize specimen collection and strict operation according to the indications of different POCT items, and correctly interpret the results of POCT based on the clinical characteristics of children and other auxiliary examination results, so as to guide clinical diagnosis and treatment.From the perspective of pediatric emergency, this review analyzed the application of POCT technology in infection-related indicators, etiology, coagulation indicators, myocardial injury, and so on.

Objective To compare the shapes of posterior corneal surface after laser subepitheliar keratomileusis(LASEK)and laser in situ keratomileusis(LASIK).Methods The 268 eyes of 134 cases were divided into two groups:The first group had 158 eyes of 79 cases,which were accepted the LASEK and whose average diopter was(-5.67?0.59)D.The second group had 110 eyes of 55 cases,which were accepted the LASIK and whose average diopter was(-5.97?0.83)D.Orbscan corneal topography system was used to follow up for 6 month postoperatively.Results In the sixth month after operation,we observed the posterior corneal power within 3mm of corneal center and the changes of the diff value between two groups.There were significantly statistical difference(P

目的观察急性心肌梗死患者早期康复护理的远期效果。方法40例老年急性心肌梗死患者随机分为实验组20例(早期康复组)和对照组20例(常规治疗组),前者接受2周的康复护理,后者接受3周的康复护理。对两组患者进行为期18个月的随访,观察其心功能、活动情况,及心绞痛和再梗死的发生率。结果两组患者的心功能无明显差异,但实验组患者心绞痛的次数和再梗死的发生率低于对照组(P<0.05)。结论对急性心肌梗死患者进行早期康复是安全、可行的,可改善心功能和降低再梗死的发生率,减少并发症的发生。

Objective The residency training questionnaires survey made at the hospital identified major residency training requirements.Methods Literature review and expert consultation were used in questionnaire design, to survey the residents of 2014 and 2015 and discover matters of their concern, and assess the policy outcomes.Results Matters of their concern were found to be professional strength, teaching and management level, and income respectively.Compared to residents of other hospitals, these residents regard the rationality of the merit pay and subsidies as higher(27.45％ vs.3.70％)in 2014.As to the new policies introduced in 2015, the gap between residents of the hospital and those from other hospitals in seeing the rationality of merit pay and subsidies tends to narrow.Conclusion The new policies have increased the residents' satisfaction on their income.

To study the therapeutic effectiveness of “Gongxuening Capsule” in the treatment of prolonged lochia. The therapeutic effectiveness of “Gongxuening Capsule” was observed in the treatment of prolonged lochia to compare with the use of antibiotic combined with Yimucao electuary. Out of 42 cases treated, significant therapeutic effectiveness was observed in the treatment of prolonged lochia by using “Gongxuening Capsule”, with the total effective rate of 95 2%. The result was better than the group of patients in whom antibiotic combined with Yimucao electuary was used ( P

There were no data concerning restenosis rate after percutaneous transluminal coronary angio-plasty available in China so far. Our study was focused on clinical and angiographic follow-up and tried to reveal the predictive value for angiographic restenosis using noninvasive tests among 592 patients whose 841 coronary arteries were dilated in our department from Dec. 1987 to Dec. 1994.This patient group consisted of 503 males and 89 females had average age of 58. 4 ? 9. 1. The overall success rate was 93. 3% and acute vessel complications was 4. 1%. After successful procedures of PTCA,the patients were followed up with recurrence of angina, Holler ECG, submaximal excercise ECG and 99mTc-MIBI exercise scintigraphy regularly. 62 of these patients underwent coronary angiographic follow-up from 4-24 months (average time: 10. 4 ? 7. 6 months) after PTCA. We found 35 patients with angiographic restenosis and 27 patients without. Thus, we divided the patients into restenosis group and non-restenosis group according to the angiographic results. Subsequently, we oberserved whether the symptom and noninvasive tests were valuable in prediction of restenosis. The result showed that recurrence of angina, Holter ECG, submaximal exercise ECG and 99mTc-MIBI scintigraphy were useful in detecting restenosis with their specificity and sensitivity 75.7% and 72.0%, 71. 4% and 86. 7%, 66. 7% and 73. 1% ,76. 5% and 83. 3 %, respectively. Moreover, If any two of above four ischemic indexes were combined together to detect restenosis,the specificity and sensitivity were significantly enhanced (85. 2% and 92. 9%). It is concluded that recurrence of angina and the noninvasive tests were valuable in predicting restenosis. The combination of these ischemic indexes would greatly improve their predictive value.

Objective To explore oligodendrocyte selective vulnerability in gray matter area and the effect of subhypothermia after transient forebrain ischemia in gerbils.Methods The gerbils model of forebrain ischemia was induced by 15 min bilateral carotid occlusion.All gerbils were divided randomly into sham operation group,ischemic reperfusion group and subhypothermia treatment group (32.5?0.5℃).Immunohistochemistry for cell specific antigens (transferrin,TF) was used to identify oligodendrocyte.Results The density of TF positive oligodendrocyte in the cortex at 1～2 days reperfusion following ischemia decreased remarkably (P

Objective To explore the relationship between reactive astrogliosis and delayed neuronal ischemic tolerance by preconditioning ischemia in gerbil hippocampal CA 1 region.Methods All gerbils were divided randomly into sham operation group,cerebral ischemia group and preconditioning ischemia group and preconditioning ischemia plus subsequent ischemia group. Transient forebrain ischemia model was induced by bilateral carotid occlution in gerbils. Immunohistochemistry for cell specific markers (glial fibrillary acidic protein(GFAP)was used to identify astrocyte.Results The numbers of GFAP positive astrocyte in hippocampal CA 1 region increased slightly at 1~7days following preconditioning ischemia, but increased significantly at 28 days after preconditioning ischemia ( P
