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 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.
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 systematically review the prevalence of depression and anxiety among health care workers in designated hospitals during the COVID-19 pandemic. Methods The Cochrane Library, PubMed, EMbase, Web of Science, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect cross-sectional studies on the prevalence of depression and anxiety among health care workers from December 2019 to April 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 14.0 software. Results A total of 21 cross-sectional studies were included, involving 38 372 participants. Meta-analysis results showed that during the COVID-19 epidemic, the prevalence of depression and anxiety among health care workers in designated hospitals were 31.00% (95%CI 0.25 to 0.37) and 44.00% (95%CI 0.34 to 0.53). The results of subgroup analysis showed that individuals of female, married, bachelor degree or above, nurses, junior professional titles, and non-first-line medical staff had higher prevalence of depression and anxiety. Conclusions During the COVID-19 pandemic, the incidence of depression and anxiety among health care workers in designated hospitals remain high. Therefore, more attention should be paid to the mental health of health care workers in designated hospitals. Due to the limited quantity and quality of included studies, more high-quality studies are needed to verify the above conclusions.
Objective To investigate the value of thyroid stimulating hormone (TSH) inhibition therapy in postoperative patients with differentiated thyroid carcinoma. Methods One hundred and six patients with differentiated thyroid carcinoma after total or near-total thyroidectomy were divided into two groups: TSH inhibition therapy group and thyroid hormone replacement therapy group. The non-recurrence and (or) non-metastasis rate in two groups was analyzed retrospectively by Wilcoxon statistical analysis. Results The non-recurrence and (or) non-metastasis rate of 3-， 5- and 10-year in TSH inhibition therapy group were 98.31%， 92.41% and 75.45% respectively， and were higher than those (93.57%， 84.18% and 52.06% respectively) in thyroid hormone replacement therapy group （P=0.046 5）. Conclusion TSH inhibition therapy after total or near-total thyroidectomy may be an essential treatment for differentiated thyroid carcinoma patients.
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 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.
ObjectiveTo evaluate the relationship between the genes involved in regulating iron uptake and maintaining iron homeostasis in Klebsiella pneumoniae from different sources and pathogenicity.MethodsThe genomic DNA sequences of two strains of Klebsiella pneumoniae from different sources were sequenced, stitched together, annotated and analyzed by second generation sequencing technique. The transversal comparison between different types of Klebsiella pneumoniae in NCBI database of iron carrier gene cluster iroB/C/D.ResultsIn these two Klebsiella pneumoniae clinical strains, the strain isolated from liver abscess patient carried 11 different iron acquisition and transportation system specific genes, which were not found in the non-liver abscess patient strain. Combined with the analysis of this sequence, in the NCBI database, six different strains of Klebsiella pneumoniae showed iroB/C/D triple positive.ConclusionIron acquisition and transportation system in Klebsiella pneumoniae may be an important pathogenic factor, which is closely related to hepatic abscess.
