The CT images of 42 pathologically confirmed cases of gastrointestinal stromal tumors were reviewed, and compared with pathological results. In 20 cases, the lesions were located in stomach, 21 in small intestine, 1 in mesentery. In 18 cases pathologically confirmed as benign tumors, 16 were positive on CT scan, which presented round solid mass with homogeneous density, mean diameter of 3.8 cm (2 -6 cm), homogeneous enhancement on post-contrast scan. In 21 malignant cases all were on CT scan, which presented irregular or lobulated solid mass with heterogeneous density and cystic change inside, mean diameter of 10. 1 cm (4 - 30 cm) , heterogeneous enhancement with no enhancement in cystic part. In 3 potentially malignant cases, CT images showed irregular solid mass with homogeneous density, diameter of 4 - 8 cm, homogeneous enhancement in post-contrast scan. CT scan can accurately show the location and size of gastrointestinal stromal tumors, and is of important diagnostic value.

Objective To explore target organ damage in the youth with pre-hypertension. Methods 77 consecutive youth visiting our institution form 2008 to 2010 were divided into pre-hypertension group (n=32) and control group (n=45). The relevance of left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVDd), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), carotid plaque intima-media thickness (IMT) and glomerular filtration rate (GFR) were compared. Results The blood pressure of pre-hypertension group was higher than that of control group, and the pre-hypertension group followed higher family hypertension history (P<0.05). There was no difference in LVDd, IVST, LVPWT, carotid plaque IMT and GFR between 2 groups (P>0.05). Compared with the control group, LVMI increased (P<0.05) and the E/A ratio decreased (P<0.05). Conclusion Target organ damage in pre-hypertension youth is salient compared with changes in renal function and damage of arteriosclerosis, and heart damage is more often occurred in the obese youth with pre-hypertension.

Objective Despite regular treatment,antineutrophil eytoplasmie antibodies(ANCA)asso- ciated systemic vasculitis(AASV),in which the role of Fc?Rs has been established,are still associated with significant long-term mortality and remain an important cause of end-stage renal failure.ANCA plays an im- portant role in the pathogenisis of primary systemic small vessel vasculitis(PSV)by their potential to activate neutrophils.Because the interaction between ANCA and its receptors on the Fc portion of immunoglobulins (Fc?R)on neutrophils is essential in the activation process,we investigate the inhibitory,effect of tg19320 on ANCA induced activation of neutrophils,which is a tetrameric tripeptide that interferes with IgG/Fe?Rs in- teraction.Methods We prepared tg19320 by solid-phase peptide syntbesis.The binding between tg19320 and human IgG was assessed by enzyme-linked immunosorbent assay.The biological activity of tg19320 to intefere with FcF?receptor recognition was identified by rosette formation assay.ANCA IgG was prepared from the sera of active Wegener's granulomatosis(WG)and microscopic polyangiitis(MPA)patients.Neu- trophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml)and then incubated with ANCA IgG(200?g/ml),or pretreated with tg19320(2.5 mg/ml)and then added with ANCA IgG.Su- peroxide burst of neutrophils was determined by Ferri-cytochrome reduction assay.Results We found that tg19320 bound tightly to human IgG in a dose dependent manner and the inhibition of the rosette formation between SRBC-IgG and U937 cells was statistically significant(20.3% vs 53.2%,P

OBJECTIVETo provide a theoretical basis for designing of lumbar intervertebral disc prosthesis by collecting the data of the lumbar endplate morphology.

METHODSA total of 100 healthy adults were measured about the following parameters: lumbar lordosis, the Cobb angle of each segment, the concavity depth (ECD) of the endplate, the location of concavity apex (ECA) of the endplate. And a correlation analysis on lumbar lordosis and ECD, ECA was made, respectively.

RESULTSIn total, 100 volunteers were measured. The mean age of the volunteer was 40 years (range 20 - 50 years); the average depth of ECD was (2. 37 ± 1. 42) mm, the average location of ECA was (52. 21 ± 9. 70) %; the average depth of ECD of inferior endplate (IEP) was (2. 81 ± 1. 52) mm (0. 54 - 7. 60 mm), and the parameter of the superior endplate (SEP) was (1. 94 ± 1. 16)mm(0. 39 - 6. 10 mm). The average depth of ECD of the IEP was bigger than of the SEP for each lumbar vertebral body. Most of the location of ECA was at the back of the intervertebral body, the average location of ECA of IEP was (49. 60 ± 8. 78) % (22. 57% - 75. 58%), and the parameter of the SEP was (55. 03 ± 9. 90) % (16. 03% -75. 58%); the mean angle of lumbar lordosis was 39. 760 11. 25°(13. 8° - 72. 00°). There was no obvious correlation between the lumbar lordosis and the ECD (r -0. 193, P =0. 195), neither was the location of ECA(r =0. 080, P =0. 592).

CONCLUSIONMost of the location of ECA is at the back of the intervertebral body, the average depth of ECD is 2. 37 mm, the average location of ECA is 52. 21%.

Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P＜0.05). The nasal symptom score dropped in both groups after treatment (both P＜0.05), and the score in the observation group was lower than that in the control group (P＜0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P＜0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P＜0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P＜0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P＜0.05) and the level of IL-4 dropped significantly (both P＜0.05); the observation group had a higher IFN-γ level (P＜0.05) and a lower IL-4 level (P＜0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P＜0.05), and the scores in the observation group were significantly lower than those in the control group (all P＜0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

BACKGROUND: According to the current most prevailed posterior pedicle screw reduction and Cage fusion for spondylolisthesis, the previous focus is to restore the vertebral sagittal displacement, and whether restoring disc height is needed and the degree of recovery remain unclear. Moreover, there is still a lack of better quantitative indicators to restore the disc height.OBEJCTIVE: By comparing the surgery of lifting reduction, to study the clinical effect of distraction and lifting reduction combined with posterior intervertebral fusion in the treatment of lumbar spondylolisthesis. METHODS: Sixty patients with L5 spondylolisthesis located in L5/S1 were selected, and were divided into two groups based on the surgery methods (n=30 per group): group A (single lifting reduction group) and group B (lifting and distracting reduction group). The patients in the group B were given distracting reduction amid insertion of 12 mm-height Cage; while the patients in the group A were subjected to lifting reduction, and intervertebral fusion with 8 mm-height Cage. The general information and the Visual Analogue Scale, Japanese Orthopaedic Association and Oswestry Disability Index scores at baseline, postoperative 1 month and last follow-up, as well as the postoperative correction and bone fusion were recorded. Additionally, the clinical effectiveness was assessed by Macnab score. RESULTS AND CONCLUSION: (1) At postoperative 1 month and last follow-up, the disc height, disc height/vertebral height, neuroforamen height and clinical effectiveness in the group B were superior to those in the group A (P < 0.05). (2) To conclude, the pedicle screw system combined with posterior intervertebral cage fusion for spondylolisthesis, can rapidly restore the disc height, contribute to restructure better biomechanics of spine. Furthermore, it significantly improves clinical systems, is easy to operate, and achieves better efficacy; therefore, it is recommended firstly.
