Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Objective:To investigate the value of neutrophil lymphocyte ratio (NLR) and systemic immune inflammatory index (SII) for the diagnosis of coronary artery lesions in patients with acute phase of Kawasaki disease (KD).Methods:It was a cross-sectional study. Children with acute Kawasaki disease admitted to Linyi Central Hospital from January 2018 to December 2021 were enrolled and divided into the Kawasaki disease complicated with coronary artery disease group (KD-CAL group) and the Kawasaki disease without coronary artery disease group (KD-NCAL group). The demographic data, blood routine and C-reactive protein (CRP) test results before intravenous injection of γ globulin were collected, and NLR and SII were calculated. Multivariate logistic regression model was used to analyze the risk factors of coronary artery disease in children with Kawasaki disease. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of NLR and SII for coronary artery lesions in children with Kawasaki disease.Results:A total of 109 children with acute phase of KD aged 1 month to 9 years were enrolled, including 66 boys (60.6%). There were no significant differences in age and gender composition between the KD-CAL group ( n=17) and the KD-NCAL group ( n=92) (all P>0.05). Compared with the KD-NCAL group, the NLR, SII and CRP levels in the KD-CAL group were higher (all P<0.05). Multivariate logistic regression analysis showed that NLR and SII were independent risk factors of coronary artery disease in children with Kawasaki disease (NLR, OR=1.265, 95% CI:1.066-1.502, P=0.007; SII, OR=1.001, 95% CI:1.000-1.002, P=0.015). ROC curve results showed that thearea under the curve ( AUC) of NLR in diagnosis of coronary artery lesions was 0.812 (95% CI:0.703-0.921, P<0.05), taking 5.4 as cutoff value, the sensitivity was 73.9% and specificity was 76.5%; the AUC of SII in diagnosis of coronary artery lesions was 0.830 (95% CI:0.741-0.919, P<0.05), taking 1 623 as the cut-off value, the sensitivity was 66.3% and specificity was 88.2%; the AUC of the combination of NLR and SII was 0.875(95% CI:0.790-0.959, P<0.05), the sensitivity and specificity were 85.9% and 76.5%, respectively. Conclusion:NLR and SII have certain diagnostic value for coronary artery disease in children with acute Kawasaki disease, and the combination of NLR and SII has better value than single index.

OBJECTIVE: To investigate the clinical characteristics and treatment of pneumocystis carinii pneumonia (PCP) in children with acute lymphoblastic leukemia (ALL), in order to improve the early diagnosis and effective treatment. METHODS: Clinical data of five children with ALL developing PCP in the post-chemotherapy granulocyte deficiency phase were analyzed retrospectively. The clinical manifestations, laboratory tests, imaging findings, treatment methods and effect were summarized. RESULTS: The male-to-female ratio of the five children was 1∶4, and the median age was 5.5 (2.9-8) years old. All patients developed PCP during granulocyte deficiency phase after induction remission chemotherapy. The clinical manifestations were generally non-specific, including high fever, tachypnea, dyspnea, non-severe cough, and rare rales in two lungs (wet rales in two patients). Laboratory tests showed elevated C-reactive protein (CRP), serum procalcitonin (PCT), (1,3)-β-D-glucan (BDG), lactate dehydrogenase (LDH) and inflammatory factors including IL-2R, IL-6 and IL-8. Chest CT showed diffuse bilateral infiltrates with patchy hyperdense shadows. Pneumocystis carinii(PC) was detected in bronchoalveolar lavage fluid (BALF) or induced sputum by high-throughput sequencing in all patients. When PCP was suspected, chemotherapy was discontinued immediately, treatment of trimethoprim-sulfame thoxazole (TMP-SMX) combined with caspofungin against PC was started, and adjunctive methylprednisolone was used. Meanwhile, granulocyte-stimulating factor and gammaglobulin were given as the supportive treatment. All patients were transferred to PICU receiving mechanical ventilation due to respiratory distress during treatment. Four children were cured and one died. CONCLUSION PCP should be highly suspected in ALL children with high fever, dyspnea, increased LDH and BDG, and diffuse patchy hyperdense shadow or solid changes in lung CT. The pathogen detection of respiratory specimens should be improved as soon as possible. TMP/SMZ is the first-line drug against PCP, and the combination of Caspofungin and TMP/SMZ treatment for NH-PCP may have a better efficacy. Patients with moderate and severe NH-PCP may benefit from glucocorticoid.

OBJECTIVE: To retrospectively analyze the identification results of irregular antibodies, to clarify the distribution features and to explore the relation of alloantibodies and autoantibodies with the immunized history of patients and disease kinds. METHODS: 49 820 patients who applied for red blood transfusion during Sep 1st 2017 to Sep 1st 2018 were selected. All the specimens were screened for the antibody by microcolumn gel antiglobulin technique, which then were identified for irregular antibody. RESULTS: Antibodies were found in 861 (1.73%) of all 49 820 transfused samples. The alloimmunization history of the patients with antibodies was significantly different between male and female (χ=18.54，P＜0.01). The alloantibody was the most common, accounting for 59.50% in all of the antibodies. Warm autoantibody, anti-E, anti-M, anti-cE and anti-Ce accounted for 68.5% of the antibodies. The blood group of Rh, MNS and Lewis were responsible for 92.40% of alloantibody, especially anti-E accounted for the largest percentage(38.60%) of alloantibody. Patients with alloantiboies experienced much more the alloimmunization and transfusion history (χ=20.13，P＜0.01；χ=5.40，P＜0.05) . The distribution of auto and alloantibody was very significantly different among the ddifferent isease (χ=51.8，P＜0.01), Hematopathy, solid tumor and osteoarthropathy were often associated with alloantibody, otherwise, autoantibodies often occurred in hematopathy and autoimmune disease. CONCLUSION The most important factor that results in antibody-screening positive is alloantibody, in which anti-E antibody from Rh blood group system in most common.

Objective    To compare the efficacy of percutaneous closure guided by transthoracic echocardiography or angiography in the treatment of patent ductus arteriosus (PDA). Methods    Literature databases such as CNKI, VIP, Wanfang Database, PubMed, Cochrane Library were searched for collecting published literatures on percutaneous closure for PDA guided by transthoracic echocardiography and angiography, retrieval time limit was up to April 2019. Two evaluators independently screened the literature, extracted the data and evaluated the quality according to inclusion and exclusion criteria. The collected data were analyzed by RevMan 5.3 software. Results    Eight studies were included finally, with a total sample size of 681 cases. Meta-analysis showed that there was no statistical difference in the operative success rate between the echocardiography group and the angiography group (RR=0.99, 95%CI 0.97- 1.01, P=0.40). Postoperative complications were less in the echocardiography group than those in the angiography group (RR=0.26, 95%CI 0.11-0.59, P=0.001).The operation time (P<0.000 01), amount of intraoperative radiation (P< 0.000 01), exposure time (P<0.000 01), hospitalization days (P<0.000 01) and hospitalization costs (P<0.000 01) in the echocardiography group were less or shorter than those in the angiography group, and the difference was statistically different. Conclusion    Compared with angiography-guided, transthoracic echocardiography-guided percutaneous closure for PDA is a safe and effective method with less trauma, lower cost, and can replace angiography as one of the guiding methods for PDA.

OBJECTIVETo assess the value of Prostate Imaging and Reporting and Data System: Version 2 (PI-RADS v2) combined with prostate specific antigen (PSA) in the diagnosis of peripheral zone (PZ) prostate cancer (PCa).

METHODSThe preoperative magnetic resonance imaging and PSA data were ananlyzed for 69 patients with pathologically confirmed PCa and 109 non-PCa patients. PI-RADS v2 scores (1-5) was used to evaluate the risk of PZ PCa. The total PSA (tPSA) level, free to total PSA ratio (f/t PSA), PSA density (PSAD), PZ-PSAD and PI-RADS v2 scores were compared between the PCa and non-PCa patients. Logistic regression models were established with parameters that differed significantly the two groups. The receiver opearting characteristics (ROC) curve was constructed based on the P values derived from the logical regression models and PI-RADS scores to assess the diagnostic efficiency.

RESULTSPI-RADS v2 score, tPSA, f/t PSA, PSAD and PZ-PSAD differed significantly between the two groups (P<0.01). Four predictive multivariate models were established: Logit P=-6.825+1.024PI-RADS v2+ 0.223tPSA (A), Logit P=-4.354+1.586PI-RADS v2-12.7841f/tPSA (B), Logit P=-8.993+1.630PI-RADS v2+17.091PSAD (C), and Logit P=-9.434+1.596PI-RADS v2+10.494PZ-PSAD (D), whose area under the ROC curves was 0.908, 0.891, 0.944, and 0.961, respectively, all significantly greater than that of PI-RADS v2 score (P<0.05).

CONCLUSIONCompared with PI-RADS v2 score alone, the combination of PI-RADS v2 score and PSA in the logistic regression model can improve the diagnostic efficiency of PZ PCa and offers better confidence in the decision of biopsy in suspected cases.

OBJECTIVETo evaluate the clinical value of modified Bethesda assay, modified Nijmegen assay and blank assay for detection of coagulation factor VIII (FVIII) inhibitors in patients with hemophilia A and analyze the factors that affect FVIII inhibitor detection.

METHODSThe levels of FVIII inhibitors in 257 patients with hemophilia A were detected using modified Bethesda assay, modified Nijmegen assay and blank assay (in which the buffer or FVIII-deficient plasma in the control mixture was replaced by deionized water). The 3 methods were compared for positivity rates and FVIII inhibitor titers based on the positive cut-off value of FVIII inhibitors ≥0.60 BU/mL.

RESULTSThe positive rates of modified Bethesda assay, modified Nijmegen assay and blank assay were 79.38%, 85.21% and 72.37%, respectively. A strong correlation was found between the results by modified Bethesda assay and modified Nijmegen assay (r=0.996, P<0.001), and FVIII inhibitor titers (P<0.001) but not the positive rates (P=0.105) detected by the two methods differed significantly. The correlation coefficients between modified Nijmegen assay and blank assay was 0.994 (P<0.001), and a significant difference was found in FVIII inhibitor titers (P<0.001) but not the positivity rates (P=0.079) detected by the two methods. The correlation coefficient between modified Nijmegen assay and blank assay was 0.994 (r=0.994), and the two methods yielded significantly different FVIII inhibitor titers and positivity rates (P=0.001).

CONCLUSIONThe modified Bethesda assay has a lower sensitivity than modified Nijmegen assay but has a higher sensitivity than blank assay. The consistency level of coagulation factors in the reaction system and stable buffer system are important factors that affect FVIII-inhibitor detection.

Objective To investigate the job satisfaction of nurses from one level three class A stomatology hospital and explore its influencing factors. Methods A questionnaire-based survey was used to examine job satisfaction of 791 nurses from the stomatology hospital in Beijing and analyze its influencing factors. Results A total of 656 effective questionnaire were collected with effective collective rate 82. 9%. The total average score of job satisfaction was (3. 24 ± 0. 92), which was at or above intermediate-level; dissatisfaction dimensions contained extrinsic rewards, family/work balance and professional opportunities. The correlation analysis showed job satisfaction was negatively correlated with age, working years and years serving in this hospital (P<0. 01). Single-factor analysis showed nurses working in different department, with different levels of formal educations, professional titles and turnover intention varied significantly in job satisfaction (P<0. 05); multiple regression analysis showed that turnover intention and age might be influencing factors of job satisfaction. Conclusions The overall job satisfaction of dental nurses is at upper level. Efficient way to increase job satisfaction may be reducing turnover intention, improving extrinsic rewards and professional opportunities.

OBJECTIVETo evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS).

METHODSSixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0. 33 g/capsule, 3 times per day) and Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day) , while those in the control group only took Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day). The therapeutic course for all was 6 weeks. IBS symptom score questionnaire, IBS-Quality of Life (IBS-QOL) , Self-Rating Depression Scale (SDS) , and Self-Rating Anxiety Scale (SAS) were assessed before and after treatment. Adverse reactions were also observed.

RESULTSThe improvement of abdominal pain, stool frequency, and stool properties, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of dysphoria, body image, concerns for health, and dietary restriction of IBS-QOL, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of SDS and SAS, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). No severe adverse reaction occurred in either group.

CONCLUSIONCombination therapy of wuling Capsule and Pinaverium Bromide could improve abdominal pain and defecation, attenuate depression and anxiety of IBS patients with higher safety.
