Objective To investigate the expressions of β1, 3-N-acetyl glucosaminyl transfrases ( Fringe) ( RFNG, LFNG and MFNG) in lung tissues and lung T cells isolated from asthmatic mice, and to explore the role of Fringe in pathogenesis of asthma. Methods Asthmatic BALB/ c mouse model was established by inhalation of ovalbumin after intraperitoneal injection. Meanwhile, the control groups were established by normal saline. Lung tissues were sampled after 24 hours since the last stimulation. T cells were isolated from the lung tissues using percol and NylonFiber. The mRNA expressions of three kinds of Fringe in the lung tissues and lung T cells were examined by reverse transcription-PCR ( RT-PCR) . The protein expressions of Fringe in the lung tissues were detected by Western blot. Results The mRNA expressions of RFNG, LFNG and MFNG were detectable in the lung tissues and lung T cells. The mRNA expressions of RFNG increased in the asthmatic group compared with the control group( lung tissues: 0. 92 ±0. 35 vs 0. 51 ±0. 13, P lt; 0. 01; lung T cells: 0. 33 ±0. 06 vs 0. 18 ±0. 07, P lt; 0. 01) . LFNG mRNA had lower expression level in the asthmatic group( lung tissue: 0. 77 ±0. 32 vs 1. 61 ±0. 31, P lt; 0. 01; lung T cells: 0. 49 ±0. 19 vs 0. 71 ±0. 03, P lt;0. 01) . No difference on the mRNA expression of MFNG was found in the lung tissues( 1. 44 ±0. 29 vs 1. 70 ±0. 44, P gt; 0. 05) . MFNG mRNA expression decreased in the asthmatic group compared with the control group in the T cells( 1. 17 ±0. 04 vs 0. 68 ±0. 07, P lt;0. 05) . The results of western blot were consistent with RT-PCR results of the lung tissues. The expressions of RFNG increased in the asthmatic group( 1. 17 ±0. 04 vs 0. 68 ±0. 07, P lt;0. 05) . The expression of MFNG has no difference between two groups( 8. 10 ±0. 60 vs 9. 12 ±0. 07, P gt;0. 05) . LFNG had a lower expression in the asthmatic group( 4. 11 ±0. 38 vs 6. 41 ±0. 11, P lt; 0. 05) . Conclusion The abnormal expressions of three kinds of Fringe may be involved in the pathogenesis of asthma.

Objective To investigate the iron regulated locus in Klebsiella pneumoniae isolates from blood culture of liver abscess patients in Sichuan Provincial People’s Hospital. Methods From January to December of 2015, a total of 10 isolates of Klebsiella pneumoniae were collected from blood culture of liver abscess patients from Sichuan Provincial People’s Hospital. The genomic DNA was extracted to identify the genes of iroB, iroC, and iroD by PCR, and data was further analyzed by Graphpad Prism 5 software. Results Among the 10 Klebsiella pneumoniae clinical strains, 9 strains were iroB positive strains, 9 strains were iroC positive strains, and 10 strains were iroD positive strains, 9 strains were iroB/C/D triple positive. Conclusion The current study suggests that the frequency of triple positive of iroB/C/D in Klebsiella pneumoniae is high in isolates from liver abscess patients, the triple positive of iroB/C/D may contribute to liver abscess.
ObjectiveTo summarize strategy of diagnosis and treatment of thrombotic iliac vein stenosis in recent years.MethodThe relevant literatures in recent 5 years on the current status and trend of diagnosis and treatment of the thrombotic iliac vein stenosis were reviewed.ResultsAt present, the diagnostic methods of thrombotic iliac vein stenosis mainly included that the multi-slice spiral CT, venography, intracavitary ultrasound, magnetic resonance imaging, color Doppler ultrasound and other imaging examinations, each of which had its advantages and disadvantages. There were still no uniform criteria whether a filter should be placed, whether the stents should and how to be placed, and when to intervene in the patients with acute thrombotic iliac vein stenosis. There was no definite conclusion when and how to effectively intervene in the patients with chronic thrombotic iliac vein stenosis.ConclusionsIncidence of thrombotic iliac vein stenosis is high and sequela is severe. Early diagnosis and reasonable treatment are very important. Only strictly grasping indications, combining medical technology and patient’s condition, and adopting appropriate treatment strategy, can make patients’ maximal benefit.
Objective To explore a scientific disease cost accounting. Method Disease cost accounting = disease cost accounting of clinic pathway + disease basis cost accounting. Conclusions It is the tendency with the medical reform for the social security department to pay by disease for the hospitals, as a result, both social security department and hospitals have to resort to the scientific way in terms of cost accounting of disease. And it is practical and effective by means of cost accounting for clinic pathway.

Methods A total of 184 patients with HFMD from May 2008 to May 2010 were randomly divided into two groups: 92 patients in the treatment group underwent medication for the external use topical with berberine tablet blending in calamine lotion for, and another 92 patients in the control group didn’t undergone the medication for the external use. Results The total cure rate within 5 days in treatment group was 94% and the total effective rate was 100%, which was significantly different from that in the control group (Plt;0.01). Conclusion Berberine tablet blending in calamine lotion application is safe and effective on patients with HFMD with infection.
Objective To review the research progress of the skin flap, fascial flap, muscle flap, and myocutaneous flap for repairing soft tissue defects around the knee so as to provide information for clinical application. Methods Domestic and abroad literature concerning the methods of soft tissue repair around the knee in recent years was reviewed extensively and analyzed. Results Fascial flaps meet the requirements of thin, pliable, and tough skin in the soft tissue repair around the knee. Myocutaneous flaps and muscle flaps have more abundant blood supply and anti-infection function. Free skin flaps are the only option when defects are extensive and local flaps are unavailable. Conclusion Suitable flaps should be chosen for soft tissue repair around the knee according to defect position, depth, and extent. Fascial flaps may be selected as the first flaps for defects repair because of excellent aesthetic results and less injury at the donor site.
Objective To establish dog model of testicular autotransplantation with a modified technique.Methods Testicular autotransplantations were performed on the right side of 30 male dogs, whose ages ranged from 1.5 to 2.0 years old and weights ranged from 14 to 17 kg. After the spermatic artery with a cuff of abdominal aorta and spermatic vein and with a cuff of inferior vena cava were detached, the testis was perfused and kept at icing temperature. An end-to-side anastomosis of the spermatic vessels to the external iliac vessels was conducted subsequently. The survival conditions of the auografts were assessed by digital subtraction arteriography (DSA). Histological examination and detection on the serum levels of follicle stimulating hormone (FSH), luteotrophic hormone (LH), and testosterone (T) were made at two weeks intervals. Results Of the 30 testicular autotransplantations performed, 27 cases were successful. The success rate was 90%. The time of heat ischemia, cold ischemia, anastomosis of spermatic vessels, and total operation was 4.5±0.9 minutes, 50.0±10.0 minutes, 35.5±5.5 minutes, and 3.5±0.5 hours respectively. DSA proved that the testis survived well. No morphological abnormality was found at different stages of the spermatogenic cells. The LH level was higherthan that before operation, being statistically different (Plt;0.05);however, the levels of FSH and T did not changed significantly (Pgt;0.05). Conclusion A stable and feasible model of testicular autotransplantation is established and it provides a reliable experimental platform for human testicular transplantation.
Objective To compare and research the process of woundhealing in occlusive moist environment and dry environment on the skin donor site. Methods The wound healing of adult skin donor site was studied by clinical observation, histological and electromicroscopical examinations on the operative day and the 1st, 2nd, 3rd, 4th, 7th days postoperatively, each skin donor site was divided into two parts: occlusive environment and dry environment. Results The wounds of occlusive moist environment healed faster than those of dry environment; thefibroblasts were more active and activated earlier, revascularization and re-epithelialization happened earlier and more quickly. Conclusion In occlusive environment, more active fibroblasts can accelerate granulation growth; quicker regenerative capillaries bring more nourishment; quicker re-epithelialization accelerates the wound healing.
