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 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.
Objectives To analyze the labeling of drug items for patients with renal insufficiency in our hospital so as to provide reference for rational use of drugs. Methods The drug instructions used in No.1 Hospital of Jilin University in 2017 were collected. According to the classification of pharmacology, the instructions of the top 9 drugs system were selected. The annotation of drug items for patients with renal insufficiency in these pharmaceutical instructions was analyzed. Results A total of 812 drug instructions were included, in which 72.17% did not mark drug instruction for renal insufficiency patients. According to the administration system, the highest unlabeled rate were digestive system drugs; according to the method of administration, the highest unlabeled rate was external preparation of drugs, accounting for 83.33%; according to production enterprises, the highest unlabeled rate were domestic drugs, accounting for 75.55%. There were only 23.40% of the tagging items having guidance of medication, and some with a certain degree of confusion in the annotation. Conclusion The unlabelling situation of drug instructions for renal insufficiency patients is very serious. It should arouse the attention of pharmaceutical manufacturers and the pharmaceutical supervisory department is suggested to strengthen the supervision of drug instructions and regulate the contents of drug labeling in drug instructions, so as to guide the rational use of drugs in clinical practice.
ObjectiveTo investigate the effectiveness of percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation in the treatment of paracentral cervical disc herniation.MethodsBetween December 2015 and October 2018, 29 cases of paracentral cervical disc herniation were treated with percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation. There were 16 males and 13 females, with an average age of 49.7 years (range, 39-78 years). The disease duration was 3.5-15.0 months (mean, 6.2 months). The herniated disc located at C3, 4 in 2 cases, C4, 5 in 5 cases, C5, 6 in 9 cases, C6, 7 in 12 cases, and C7, T1 in 1 case. The main symptoms were radiculopathy symptom. The operation time, intraoperative blood loss, hospital stay, and complications were observed and recorded. Visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, cervical range of motion (ROM), Macnab standard, and cervical segment stability were used to evaluate the efficacy and safety of the operation.ResultsAll patients were followed up 11-43 months, with an average of 19.4 months. The operation time was 67-89 minutes (mean, 73.3 minutes); the intraoperative blood loss was 18-30 mL (mean, 22.9 mL); the hospital stay was 5-10 days (mean, 7.3 days). All the incisions healed by first intention. There was 1 case of hypodynia and hyperalgesia in the affected limb after operation,1 case of decreased limb muscle strength. The VAS scores and JOA scores at each time point after operation were superior to those before operation (P<0.05). There was no significant difference between the time points after operation (P>0.05). At last follow-up, the effectiveness was rated according to the Macnab standard as excellent in 11 cases, good in 15 cases, fair in 2 cases, and bad in 1 case, with an excellent and good rate of 89.7%. The CT and MRI showed the decompression of spinal canal and nerve canal. There was no significant difference in cervical ROM between pre- and post-operation (t=1.427, P=0.165), and no surgical segment instability occurred by X-ray films of flexion and extension of cervical vertebrae.ConclusionFor the paracentral cervical disc herniation with simultaneous compression of nerve roots and spinal cord, percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation has the advantages of small trauma, quick recovery, and satisfactory effectiveness, and can be used as a safe and effective minimally invasive procedure.
ObjectiveTo systematically review the influence of childhood psychosocial stress on pubertal emotional and behavioral problems. MethodsThe PubMed, OVID, EBSCO, Web of Science, CBM, VIP, WanFang Data and CNKI databases were electronically searched to collect studies on the relationships between childhood psychosocial stress and pubertal emotional and behavioral problems from inception to February 29, 2024. Two reviewers independently screened the literature, extracted data and assessed the risk of bias in the included studies. Qualitative methods were then used to analyze the data. ResultsA total of 41 cohort studies were included. The outcomes of 19 studies involved pubertal emotional problems, 26 studies involved behavioral problems, and 7 studies involved overall problems. The results showed that depression (14/19) and anxiety (8/19) were the most commonly reported emotional behaviors. Most studies (17/19) showed that childhood psychological stress had a positive predictive effect on pubertal emotional problems. Behavioral problems involved many outcomes, including smoking, drinking, illegal substance use, self-injurious behavior, suicide, externalizing behavior, criminal behavior, bullying behavior, sexual behavior, mobile phone dependence, etc. However, few studies were on the same behaviors, and the relationship between childhood psychosocial stress and behavioral problems was unclear. ConclusionChildhood psychosocial stress may have a positive predictive effect on depression and anxiety. The associations between childhood psychosocial stress and pubertal behavioral problems and other emotional problems remain to be determined by more studies.
Speech imagery is an emerging brain-computer interface (BCI) paradigm with potential to provide effective communication for individuals with speech impairments. This study designed a Chinese speech imagery paradigm using three clinically relevant words—“Help me”, “Sit up” and “Turn over”—and collected electroencephalography (EEG) data from 15 healthy subjects. Based on the data, a Channel Attention Multi-Scale Convolutional Neural Network (CAM-Net) decoding algorithm was proposed, which combined multi-scale temporal convolutions with asymmetric spatial convolutions to extract multidimensional EEG features, and incorporated a channel attention mechanism along with a bidirectional long short-term memory network to perform channel weighting and capture temporal dependencies. Experimental results showed that CAM-Net achieved a classification accuracy of 48.54% in the three-class task, outperforming baseline models such as EEGNet and Deep ConvNet, and reached a highest accuracy of 64.17% in the binary classification between “Sit up” and “Turn over”. This work provides a promising approach for future Chinese speech imagery BCI research and applications.
