Objective To observe the operation process implementation and the therapeutic effect of interventional therapy for the superior mesenteric artery thrombosis.Methods 21 cases with superior mesenteric arterial thrombosis who had the diagnosis and clinical treatment in our hospital from January 2005 to December 2013 were retrospectively analyzed.Results Among 21 cases,19 cases had obvious risk factors,and their early symptoms and signs were not consistent.The artery angiography showed that 17 cases had superior mesenteric artery thrombosis,2 cases had ileum arterial thrombosis,2 cases had inferior mesenteric arterial thrombosis.All surgeries were performed successfully.The length of hospital stay was 10 14 days with an average of 11 days.After interventional treatment,the symptom of abdominal pain had obvious remission.The follow-up period was 12 to 36 months and no recurrence was found.Conclusions The diagnosis of mesenteric arterial thrombosis is difficult.Mesenteric arterial thrombosis needs the early diagnosis and timely interventional treatment.

Objective To explore the clinical and radiographic outcomes of minimally invasive transforarninal lumbar interbody fusion (MIS-TLIF) with unilateral pedicle screw fixation in treatment of one-level lumbar degenerative disease.Methods A total of 65 patients suffered from one-level lumbar degenerative disease between October 2009 and December 2011.They were divided into 2 groups according to different fixation ways.31 patients were given MIS-TLIF with unilateral pedicle screw fixation.The other 34 patients were given MIS-TLIF with bilateral pedicle screw fixation.Microscopic tubular retractor system (METRxMD) and Sextant system were used in all the procedures of treatment.The whole lumbar lordosis (WL),the segmnental lordosis (SL),fusion level disc space angle,lumbar scoliosis angle,and segmental scoliosis angle were measured pre and post operation according to standarded X-rays.The disc height index (DI) and the lumber curvature index (LI) were also evaluated.The Oswestry disability index (ODI) score and visual analog scale (VAS) pain score data were obtained from all the patients pre-operation and during each following-up procedure.Results All the patients were well followed up 18 months to 36 months(average 26.6 months).All the 65 patients were proved to achieve bone fusion in 12 months post-operation.The ODI and VAS scores post-operation improved significantly in each group,but showed no significant difference between the 2 groups.Likewise,there were no significant differences between the 2 groups in datas of WL,SL,fusion level disc space angle,lumbar scoliosis angle,segmental scoliosis angle,DI,and LI.But there was a positive linear correlation between the LI and WL in the 2 groups.Conclusion MIS-TLIF with unilateral pedicle screw fixation is as good as MIS-TLIF with bilateral pedicle screw fixation in patients of one-level lumbar degenerative disease.

Objective To observe the clinical effects of ultra-sound guided lumbar plexus and sciatic plexus nerve block combined with general anesthesia on elderly patients undergoing hip replace-ment surgery.Methods Eighty elderly patients scheduled for unilateral hip replacement surgery were randomly divided to lumbar plexus and sciatic plexus nerve block combined with general anesthesia group (group N)and general anesthesia group (group G).The airways of all the patients were con-trolled by laryngeal mask airway (LMA)in both groups.The bispectral index (BIS)of patients in both groups was maintained in the range of 45-55.The dosage of sulfentanyl,visual analogue scale (VAS)at 2,4,8 and 24 h after surgery,and the dosage of patient controlled analgesia (PCA)drugs were recorded.The period from end of surgery to extubation,off-bed activity and discharged from hospital,mortality in 30 days after surgery were recorded.Meanwhile,postoperative delirium (POD) and postoperative cognitive dysfunction (POCD),and severe cardiovascular and pulmonary complica-tions were evaluated.Results No patient died in 30 days after surgery in both two groups.One patient suffered from severe pulmonary infection in group G.The dosage of sulfentanyl of group N was less than the value of group G (P <0.05),the periods from end of surgery to extubation,off-bed activity and discharged from hospital of group N were shorter than those in group G (P <0.05 ).The VAS scores and incidence of POD and POCD in group N were lower than those in group G (P < 0.01 ). Conclusion In elderly patients undergoing hip replacement surgery,ultrasound-guided lumbar plexus and sciatic plexus nerve block combined with general anesthesia could help reduce usage of opioids during operation,offer better analgesia effect,shorten the period of off-bed activity and discharged from hospital and reduce incidence of POD and POCD in elderly patients.

Objective To explore the success rate and the risk of establishment of the acute myocardial infarction model between the beagle dogs and the mini-pigs by interventional technique ,further to provid theoretical basis for choose a more suitable animal model .Methods 6 dogs and 6 mini-pigs were anaesthetized ,then underwent the coronary arteriography via femoral artery .After is-chemic preconditioning the coronary balloon was inflated to occlude the middle left anterior descending coronary for 180 minutes . The electrocardiogram was examined throughout the operation and the pathological sections were examined until the animals were executed one week later .Results All beagle dogs survived ,while 1 case of mini-pigs dead(1/6) .There was 1 cases(1/6) of beagle dogs had acute myocardial infarction ,while 5(5/6)cases in mini-pigs .All mini-pigs had malignant arrhythmia(6/6) but never seen in beagle dogs .The time needed for building a model was similar between the two groups ,the difference had no statistical signifi-cance(P>0 .05) .Conclusion The risk of establish myocardial infarction model in mini-pigs is higher than beagle dogs ,but the suc-cess rate is still high ,it might be the better choice .

To investigate the effect of NVP-DPP728, a DPP-Ⅳ inhibitor on new-onset diabetes and the autoimmune response in non-obese diabetic ( NOD ) mice. Diabetes could be reversed in 75% of NVP-DPP728 treated 20 NOD mice. In these 15 mice with remission, insulitis scores were significantly lower than those of the control group. The percentage of Tregs was increased in the thymus and celiac lymph nodes, plasma TGF-β1 and GLP-1 were also significantly increased ( P＜0. 01 ). NVP-DPP728 treatment may reverse new-onset diabetes in NOD mice by reducing insulitis and increasing Tregs.

Objective To analyze the clinical data and TUBB4A mutation of hypomyelination with atrophy of the basal ganglia and cerebellum (HABC)in a family,thus to provide accurate genetic counseling and prenatal diagno-sis for this family with HABC,and also to provide clinical experience for the diagnosis of HABC in China.Methods The clinical data of the proband and her family members were collected at the Department of Pediatrics,Peking Univer-sity First Hospital,December 201 4,including medical history,physical signs,and brain MRI,biochemical tests and metabolic disease screening.The associated gene of hereditary leukoencephalopathy was screened for the proband and her family members were screened by targeting -high -throughput sequencing technology,and then the genetic varia-tions were verified by Sanger sequencing.With those detection methods,the gene mutation was confirmed,and then ge-netic features were analyzed.Results Clinical features were as follows:nystagmus as the first symptom,and motor and mental retardation,dystonia and ataxia followed.Brain MRI indicated hypomyelination of white matter and atrophy of the basal ganglia and cerebellum.The clinical diagnosis of HABC was established based on the clinical features and brain MRI features above.Genetics features showed that one novel TUBB4A c.974G >T heterozygous missense muta-tion was found from the proband,which caused an amino acid change from the Trp into Leu (p.Trp325Leu).Both of her parents with normal phenotype were of wild -type in this site.Conclusions The proband from this family was diagnosed clinically based on her clinical data.One novel TUBB4Ac.974G > T (p.Trp325Leu)was founded in this study.Therefore,the spectrum of TUBB4A mutation will be expanded.In addition,this study elucidated clinical and genetic characteristics in this family with HABC,which may lay a solid foundation for the accurate genetic counseling and prenatal diagnosis.This study reported the first case of HABC caused by TUBB4A mutation in China.

The infection by Limnodrilus hoffmeisteri Claparède, 1862 (Oligochaeta: Tubificinae) in humans is relatively uncommon. The present report is to describe an incidental human infection with oligochaetes in the nasal cavity of a Chinese man, a 25-year-old man residing in Zhangjiakou city, Hebei province, China presenting with nose bleed, severe itching, continuous sneezing, and rhinorrhea. A lot of oligochaete worms were found in the nasal discharge of the patient. The detected worms were identified as Limnodrilus hoffmeisteri (Annelida: Oligochaeta) based on morphological and molecular characteristics. This incidental L. hoffmeisteri nasal infection is the first case in China and indicates that oligochaete worms can be encountered in humans.
