Objective To analyze the clinical manifestation, diagnosis and treatment of acute mesenteric vascular obliteration (AMVO). Methods 112 cases of AMVO were analyzed, including 20 cases admitted to our hospital from 1992 to 2004 and 92 cases reported by other hospitals. Results Abdominal pain, abdominal distension, nausea and vomiting, decrease or disappearance of bowel sound, elevation of white blood cell count were more frequent manifestations.Cardiovascular disease, portal vein stasis or hypercoagulation state were common findings in patients' history. The average misdiagnosis rate of AMVO in these 112 patients was 61.5%, with a misdiagnosis rate of 45.0% in 20 cases of our hospital. The average mortality rate of all these patients was 41.9%, with a mortality rate of 30.0% for 20 cases of our hospital. Conclusion The early clinical manifestation of AMVO lacks specificity, the misdiagnosis ratio and mortality rate are very high. Angiography should be done early to confirm the diagnosis and improve the therapeutic effect in the patients suspicions of having this ailment.

Twenty-eight moderately halophilic bacteria isolated from salt lakes in Xinjiang Regions were analyzed by 16S rDNA PCR-RFLP in comparison with nine reference strains of related species. The 16S rRNA PCR products of the tested stains were digested by four restriction enzymes (AluI, HinfI, RsaI and HaeⅢ). The results showed that all tested strains were clustered into three groups at 74% similarity level. Group I included 2 reference strains Chromohalobacter marismortui, Nesterenkonia halobia and new isolate CI. Group Ⅱ included seven type strains belonging to Halomonas and eight new isolates. Group Ⅲ included ninteen new isolates.

A bacterial cell surface display technique based on an ice nucleation protein has been employed for the development of live vaccine against viral infection.Due to its ubiquitous ability to invade host cells,Salmonella typhimurium might be a good candidate for displaying viral antigens.We demonstrated the surface display of domain III of Japanese encephalitis virus E protein and the enhanced green fluorescent protein on S.typhimurium BRD509 using the ice nucleation protein.The effects of the motif in the ice nucleation protein on the effective display of integral protein were also investigated.The results showed that display motifs in the protein can target integral foreign protein on the surface of S.typhimurium BRD509.Moreover,recombinant strains with surface displayed viral proteins retained their invasiveness,suggesting that the recombinant S.typhimurium can be used as live vaccine vector for eliciting complete immunogenicity.The data may yield better understanding of the mechanism by which ice nucleation protein displays foreign proteins in the Salmonella strain.

AIM:To evaluate the availability and our experience of intraoperative image-guidance in endoscopic nasocular operation.METHODS:Seven cases of endoscopic nasal surgery with intraoperative image-guidance were retropectively reviewed,including 3 cases of optic nerve injury;3 cases of foreign object of optic behind the eyeball;1 case of retrobulbar tumor(angeioma).RESULTS:The preoperative preparatory time would take 15 minutes,including coordination,head holder localization,conventional instrument registration.In our cases,the localization accuracy between 3-D image landmarks of navigation system and actual anatomical landmarks was less than 1.3mm.The optic nerve and other anatomical points could be orientated accurately in intraoperative procedures.No complication occurred.CONCLUSION:Nasal endoscope combined with imageguidance systems provides accurate anatomical localization of anterior skull base with enlarged operation field.It is possible for surgeons to observe important anatomical structures during endoscopic surgery.It could increase the effectiveness and decrease surgical complications,especially in complicated cases.

Objective To observe the effect of comprehensive nursing of traditional Chinese medicine and Western Medicine on children′s supracondylar humerus fracture of ulnar deviation on postoperative recovery. Methods From November 2015 to February 2016, 52 inpatients were divided into 2 groups by random digits table method after the external fixation removal surgery with 26 cases each. The observation group was intervened by integrated nursing and was given TCM rehabilitation guidance, while the control group was intervened by regular nursing and was given regular rehabilitation guidance. After 4 weeks, the therapeutic effect was evaluated according to Chinese Medicine Orthopedic Syndrome Diagnosis and their elbow joint function was evaluated by Flynn score. In 8 weeks of follow up, all the patients were valued by their quality of life. Results In the process of intervention, with 1 case fell off in the observation group, 3 cases fell off in the control group, so finally the observation group with 25 cases, the control group with 23 cases. Fifteen cases were cured, 7 cases were improved, 3 cases were not cured at 4 weeks after surgery in the observation group, 8, 6, 9 cases in the control group, and the difference was statistically significant (Z=-2.120, P=0.034). At 4 weeks after surgery, 10, 6, 6, 3 cases were excellent, good, medium and poor evaluated by Flynn score in the observation group, 5, 4, 5, 9 cases in the control group, and the difference was statistically significant (Z=-2.051, P=0.040). Incidence of postoperative complications was 8.0% (2/25) in the observation group, 30.4% (7/23) in the control group, and the difference was statistically significant (χ2=2.622, P=0.047). Physical, psychological, social and environmental fields of quality of life were 77.84 ± 12.15, 81.13 ± 15.72, 79.95 ± 20.68, 79.44 ± 11.57 in the observation group, 63.31 ± 15.86, 63.07 ± 12.63, 65.65 ± 18.51, 61.32 ± 17.24 in the control group, and the difference was statistically significant (t=2.516- 4.363, P<0.05). Conclusions Integrated nursing intervention with TCM rehabilitation guidance is a method which can effectively help in improving the elbow movement function and the life quality of children with supracondylar humerus fractures of ulnar deviation.

Objective To investigate the lateralizing value of head deviation(HD) during complex partial seizures (CPS) in patients with refractory mesial temporal lobe epilepsy (mTLE).Methods Presurgical videotypes of 43 patients who were seizure-free for at least one year after temporal lobectomy were retrospectively reviewed.Attention was paid to the relationship between time and type of HD and the side of epileptogenic zone.Results HD was seen in 88 CPS from 43 patients who had total 206 CPS with or without secondary generalization.Both versive and non-versive HD displayed high positive predictive value (83％ (33/40) and 88％ (22/25)) for localization of an ipsilateral and contralateral seizure onset,respectively.Conclusion Both non-versive HD and versive HID during CPS in patients with mTLE are reliable lateralizing signs that can complement other diagnostic modalities in presurgical evaluation.
