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.

Objective Discussing the rationality of psychological intervening therapy in the treatment of early breast neoplasm. Methods By summarizing and reviewing 84 patients suffering from the early breast cancer between January of 2003 and December of 2005, we procured some information of their clinical manifes-tations, clinical therapy and statistic results of psychological assessment. Results By intervening the psycho-logical therapy, the patients' self-efficiency and living quality can be bettered. Conclusion Patients with early breast neoplasm need to have a comprehensive treatment with general or local therapy and individual psychologi-cal intervention. Nevertheless, it is rather practical to enhance the general level of prevention and therapy of breast neoplasm through the research of psychological problems after the operation.

Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P＜0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P＜0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P＞0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.

Recently, stem cell like side population (SP) cells have been found in many normal organizations and malig?nant tumors, which have the proficiency of differentiation and self-renewal. These cells play an important role in cancer stem cell research, though they occupy a low proportion in total cells. Here, we reviewed the foundation of SP cells, and their rela?tionship with stem cells, and the clinical application in the future.

Objective To investigate the pulmonary imaging findings and the clinical characteristics of ANCA-associated vasculitis.Methods 16 patients with ANCA-associated vasculitis confirmed by pathology in our hospital were analyzed retrospectively,all patients underwent 1 6-sclice high resolution chest CT scans.The clinical manifestations and lung CT findings of the patients were analyzed.Results The mean age of 1 6 patients (7 male and 9 female)was 62.7 (ranged from 56 to 83).The onset time of the disease was ranged for 1 weeks to 2 years,and it was characterized as multiple organs involvement accompanied by kidney damage with different degrees.The clinical respiratory symptoms inluded fever and cough.The lung HRCT features of ANCA-associated vasculitis were as follows:patchy shadow in 14 cases (87.5%),streak one in 12 (75%),nodular one in 3 (18.8%),cavities in 4 (25%),emphysema and pulmonary bullae in 6 (37.5%),tree-in-bud in 6 (37.5%),pleural effusion in 4 (25%),mediastinal lymph nodes enlargement in 3 (18.8%), pleural thickening in 6 (37.5%),cellular-like in 5 (31.3%),bronchiectasis in 6 (37.5%),round-glass opacity in 10 (62.5%)and reticulate changes in 8 (50%).Some patients were treated by the glucocorticoid (a hormone steroid)or by it in combination with immunosuppressant, and the clinical symptoms were improved and some lesions on X-ray images were significantly reduced or disappeared.Conclusion ANCA-associated vasculitis usually occurs in the majority of middle or old age without gender difference.Multiple organs are easily involved and the lesions in lung may be misdiagnosed as infection.Early CT diagnosis and timely treatment may improve the prognosis.

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.
