To investigate the features of CT, ultrasonography and fundus fluorescein angiography (FFA) of morning glory syndrome, the data on CT, A/B-scan ultrasonography and fundus fluorescein angiography (FFA) were retrospectively analyzed in 8 cases of morning glory syndrome (MGS). Among those cases, 6 were examined with CT, 4 with FFA and 8 with A/B-scan ultrasonography. Results showed that the characteristics of CT, A/B-scan ultrasonography and FFA in MGS included: (1) The attachment spot of optic nerve became thin and vitreous body protruded to the posterior wall of eyeball with a spherical shape on CT image; (2) in the early period of FFA, hypofluorescence appeared on the optic, the abnormal arteriae and veins around the optic papilla were displayed clearly and in the late period, optic disc was stained with fluorescein; (3) on B-scan ultrasonogram, the vitreous cavity extended to the posterior pole and optic papilla, and projected to the basal part of muscle cones and thus the posterior part of vitreous cavity looked like an upside-down bottleneck. Sometimes the echogenic band of retinal detachment could also be seen. On A-scan ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echoes and presented a base line without any evident wave crest. It is concluded that CT, A /B-scan ultrasonography and FFA could show the imageological features of MGS from different aspects, which helps clinicians to differentiate it from other diseases such as optic disc coloboma. CT and A /B-scan ultrasonography, in particular, are considered to be reliable imageological methods for the accurate diagnosis of MGS and are superior to the traditional techniques.

Objective To explore the pathologic changes of the opening blood-brain barrier(BBB) in the early stages of 50% TBSA scalded rabbits.Methods Ten male rabbits inflicted with 50% TBSA of Ⅲ degree were randomized into five groups: control,postburn 1 h,2 h,3 h,4 h.Brain tissues were isolated at different phases and observed in gross,by microscope and transmission electron microscope.Results Endothelial cells swelled and BBB began to open in 2 h after scald.The tight junction of endothelial cells became vague and the opening of BBB increased as lesion time prolonged.Conclusion As the lesion time prolonged,the injury of endothelial cells became more serious and the opening of BBB progressed,which resulted in the formation of brain edema.

In recent years, there is increasing evidence that the pathogenesis of Parkinson's disease (PD) may involve the more generation of reactive oxygen species, and investigations on patients have shown that PD is under a status of oxidative stress. The defense against the toxic effects of reactive oxygen species is an essential task within the brain. An important component of the cellular detoxification of reactive oxygen species is the antioxidant glutathione. Consequently, it seems reasonable to propose that increase of brain concentrations of glutathione including glutathione analogs or precursors could be very effective in diminishing the cumulative effects of oxidative damage, and have been investigated as potential therapeutic targets in the treatment and prevention of PD or other neurodegenerative disease.

Many countries have developed standard strategy under the tendency of the economic globalization.TCM international standardization faces more and more competitions.This article analyzes the competitors and competitive status of TCM international standardization by the research methods of competitive intelligence,competitor analysis and SWOT analysis,and puts forward corresponding strategic measures in details.

Objective To investigate the role of temporary placement of fully covered self-expandable metal stent (cSEMS) for treatment of uncontrolled bleeding after endoscopic sphincterotomy (EST).Methods From January 2000 to present,a total of 3460 cases of EST were performed,and bleeding after the procedure was complicated in 29 (0.84％) of them,in which 4 could not to be stopped by conventional managements.Covered SEMSs were placed across the major papilla in these 4 patients.Results The stents were successfully placed and hemostasis was achieved in all patients.The stent was removed in 1 patient 1 week later,and spontaneous stent dislodgment occurred in 1 patient within 4 weeks.The other 2 patients rejected to remove the stents,and the patency maintained for more than 6 and 12 months respectively.No complication was observed in procedures of placing and removing stents.Conclusion Covered SEMS placement is a safe,effective and simple method for patients with uncontrolled bleeding after EST.

Aerobic glycolysis,which is also termed as Warburg effect,is one of the most common and profound biochemical phenotypes of tumor ceils.Several oncogenes and tumor suppressors genes have been implicated in aerobic glycolysis.MicroRNAs can control this metabolic switch by regulating oncogenes and tumor suppressors genes in a post-transcriptional way.A deeper understanding of the mechanisms and pathways by which miRNAs regulate the aerobic glycolysis will hopefully lead to a new therapeutic strategy for malignant cancer.

[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

Growth arrest special 5 (GAS5) is a common long non-coding RNA (lncRNA).Recent studies find that lncRNA GAS5 is down-regulated in various tumors,such as breast cancer,cervical cancer,lung cancer,gastrointestinal cancers and urologic cancers.GAS5 is closely related to the development,metastasis and prognosis of cancers,which becomes a new hotspot in cancer research.

Objective To investigate the risk factors for postoperative anastomotic leakage in geriatric patients with esophageal carcinoma and provide new insights into clinical prevention and treatment.Method The fifty-six patients with anastomotic fistula were chosen from 636 esophageal carcinoma patients who underwent esophagectomy in Department of Thoracic Surgery from January 2011 to January 2016.In the 56 patients,the ratio of male (39 cases) to female (17 cases) was 2.3 ∶ 1.0,with the age range of 60-81 years,average of (66.4±8.6) years.The retrospective analysis was performed for obtaining the risk factors for anastomotic leakage.Results Fifty six cases who suffered from anastomotic fistula showed 10 cases (17.9％)with hormone administration,17 cases (30.4％) with preoperative chemo-radiotherapy,32 cases (57.1％) with the basic diseases,27 (48.2％) with preoperative dystrophia.In addition to the old age and tumor,the other risk factors for anastomotic leakage included the hormone use,preoperative malnutrition,and preoperative chemoradiotherapy.Conclusion High attentions have to be paid to the prevention and treatment of anastomotic fistula patients with chronic diseases,hormone use,preoperative malnutrition and preoperative chemo-radiotherapy.
