Objective To study the relationship between velocity of middle cerebral artery(MCA),severity of disease and watershed infarction(WSI) in patients with extracranial internal carotid artery(EICA) stenosis or occlusion.Methods Transcranial Doppler(TCD) was used to detect the mean velocity(MV) of MCA in 120 patients with EICA stenosis or occlusion.The National Institutes of Health Stroke Scale(NIHSS) was used to evaluated the patients′ condition.And CT or MRI was used to diagnosised the WSI.Results MV of MCA was severe reduced in 10 cases,middle reduced in 38 cases,and mild reduced in 42 cases,while there were 30 cases with normal MV.The scores of NIHSS in the four groups(12.5?4.7,3.9?4.8,3.2?4.7,2.4?4.9 respectively) had significant different(P

Surgical treatment is the only cure treatment for patients with inferior vena cava tumor thrombus in hepatic segment and upper hepatic segment.The accurate diagnosis of tumor thrombus is very important.In preoperative imaging examination,the abdominal enhanced CT scan and the inferior vena cava MRI scan were the best methods for the diagnosis and evaluation of the tumor thrombus in hepatic segment and upper hepatic segment.Compared with the tumor thrombus below the liver,the tumor thrombus in hepatic segment or above hepatic segment extend widely,and the operation are more difficult.For simple inferior vena cava tumor thrombus (the top of the thrombus has reached the level of hepatic vein),Retroperitoneal approach combined with transperitoneal approach should be used.Open surgery is the standard procedure for other tumor thrombus in hepatic segment and upper hepatic segment.In addition to exposure of inferior vena cava below the hepatic vein,the liver and the first hepatic hilum should be exposed.For tumor thrombus in the atrium,after the longitudinal incision of diaphragm,we use Milking technology to squeeze thrombus into inferior vena cava.Then we use catheterization technology to remove thrombus.For difficult atrial tumor thrombus,an extracorporeal circulation should be performed.The median incision in the chest should be performed to open the chest and open the pericardium and remove the tumor thrombus.Patients with tumor thrombus in hepatic segment or upper hepatic segment should be diagnosed as early as possible and they need actively treated by operation.

"Treatment based on diseases identification and formulas corresponding to diseases" is one of important therapy modes of Chinese medicine. Although it originates from Huangdi Neijing, it is seldom systematically discussed. Modern Chinese medicine (CM) now faces diseases mostly with comparatively confirmed Western medical diagnoses. Most of them have specific pathophysiological changes. How to interpret these specific pathophysiological changes, play CM's advantages, and improve clinical efficacies has become an inevitable problem for modern CM in clinic. Authors expounded historic development and clinical application of "formulas corresponding to diseases", and its difference from "formulas corresponding to syndromes", put forward that we should combine "formulas corresponding to diseases" and "formulas corresponding to syndromes" in CM clinics. We should focus on the disease and summarize treatment rules, thereby improving targeted CM formulas.

Objective To discuss the value of vertebral hemangiomas treated with the CT-guided pereutaneous vertebroplasty (PVP).Methods Forty-two patients with 49 vertebral lesions were guided by CT and injected with bone cement percutaneous into the vertebral.The effectiveness was valued by preoperative and postoperative visual analogue scale (VAS),locomotor activity scores,pain medication scores and comprehensive evaluation of long-term efficacy of WHO criteria,and undertook statistical analysis.Results The success rate in all patients was 100.0％(42/42),no serious complications.All the patients were followed up for 6 - 18 ( 12.50 ± 1.15 ) months,all lesions of the vertebral body imaging showed no tumor recurrence and vertebral collapse.The VAS scores decreased from preoperative (7.64 ± 1.29 ) scores to postoperative 1-3 days (4.82 ± 1.21 ) scores and to postoperative 3 -6 months (0.22 ±0.19) scores (P＜0.05).The locomotor activity scores decreased from preoperative (3.4 ± 0.9) scores to postoperative 1-3 days (2.1 ±0.6) scores and to postoperative 3-6 months (1.0 ±0.3) scores (P＜0.05).The pain medication scores decreased from preoperative ( 1.9 ± 0.6) scores to postoperative 1 - 3 days months ( 1.1 ± 0.2 ) scores and topostoperative 3-6 months (0.2 ± 0.1 ) scores (P ＜ 0.05 ).Comprehensive evaluation of long-term efficacy of WHO criteria:efficiency rate was 97.6％(41/42).Conclusions CT-guided percutaneous vertebroplasty for vertebral hemangioma can effectively relieve the pain caused by vertebral body to increase stability,improve motor function,which is a method with safe,minimally invasion,effect,and is superior than C-arm fluoroscopy.

Gastrointestinal stromal tumor is one kind of the most common gastrointestinal tumors derived from the mesenchymal tissue.In most cases,it occurs in adults,while rarely occurs in adolescents.The clinical diagnosis of pediatric GIST can refer to the diagnosis standard of adults GIST,but it pays more attention to genetic diagnosis.The main treatment for pediatric GIST is surgery,but for advanced or unresectable patients,we can adopt imatinib or sutent for targeted therapy according to the results of genetic testing.

Objective To explore the psychological experience and the needs of parents who had children with leukemia in order to provide the theoretical and practice reference for clinical nursing work.Methods A qualitative phenomenological methodology was used in this study.10 parents of children with leukemia were interviewed with semi-open-ended questions.The NVivo10.0 software was used to supervise,excavate and seek data.The Colaizzi phenomenological methodology was used to analyze the data.Results Through careful analysis,four themes were identified:leukemia news was like crowning calamity; psychological changes generally varied in different stages; pressure had pluralism as well as the diversity of coping.The demand had multipolarity.Conclusions Attention should be paid closely to parents with leukemia children.The individualized measures should be taken by medical workers in order to provide them with mental nursing and holistic nursing and make them stay in a best health state,so that they can supply better social support for these children.

Recent studies show that epileptic seizures result in mass free radical production and induce oxidative damage because of relative deficiency in anti-oxygen system.Mitochondrium is crucial to sustaining energy metabolism,regulating cell death,synthesising neurotransmitter and oxidating fatty acid.Mitochondrium is not only the place for free radical production,but also the target of oxidative damage.Mitochondrial oxidative stress and resultant dysfunction enhance epileptic susceptibility.Seizure-induced free radical can influence energy metabolism,destroy DNA construction and induce apoptosis in neurontoxic consequences in epilepsy.
