Objective To analyze the current situation of healthcare-associated infection (HCAI) management of fever clinics among different levels of medical institutions in Wuhan, and to provide a scientific basis for improving hospital infection management. Methods In January 2023, a network questionnaire survey was conducted on medical institutions with fever clinics in Wuhan. Results A total of 72 medical institutions were investigated, of which 58.33% had CT, and 48.61% had fever clinics for children. The total qualified rate of HCAI management was 78.28%. The qualified rates of four primary indicators, including hospital management, diagnosis and treatment environment protection, training and education, and implementation of infection control measures, were 82.27%, 71.49%, 75.93%, and 81.31%, respectively. There were statistical differences among different levels of medical institutions (all P<0.01). Among the 13 secondary indicators, the qualified rates of 7 indicators were more than 80%, with the highest being medical item management (93.06%), medical waste disposal (89.72%), and personnel management (83.33%), and the lowest being facilities and equipment (66.32%), and patients and accompanying personnel education (66.67%). Among the 65 tertiary indicators, 30 had a pass rate great than 80%. Conclusion Wuhan actively promotes the construction of fever clinics in medical institutions, and the overall situation of HCAI management is good. However, there are still some problems to varying degrees, especially in the layout procedures, hand hygiene, and staff training of fever clinics in secondary and lower medical institutions, which should be further strengthened.

Objective: To assess the feasibility of nuclear score combined with cyclin D1 immunocytochemistry in classifying indeterminate thyroid nodules with fine-needle aspiration (FNA) cytological diagnosis of Bethesda category Ⅲ-Ⅴ. Methods: A consecutive cohort of 118 thyroid FNA specimens with indeterminate diagnosis (TBSRTC category Ⅲ-Ⅴ) and available histopathologic follow-up data were collected between December 2018 and April 2022 at the Department of Pathology, Beijing Hospital, China. These cases were subjected to cytological evaluation and cyclin D1 immunocytochemistry. The optimal cut-off points of a simplified nuclear score and the percentage of cyclin D1-positive cells for the diagnosis of malignancy or low-risk neoplasm were determined using the receiver operating characteristic (ROC) curves and area under the ROC curve (AUC). The specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) of nuclear score and cyclin D1 immunostaining were evaluated from the crosstabs based on cut-off points. The diagnostic accuracy of simplified nuclear score combined with cyclin D1 immunostaining was estimated using ROC curve analysis. Results: Nuclear grooves, intra-nuclear inclusions and chromatin clearing were more commonly found in malignancy/low-risk neoplasms than benign lesions (P=0.001, P=0.012 and P=0.001 respectively). A cut-off point of≥2 for the simplified nuclear score was sensitive for defining malignancy/low-risk neoplasm, and its PPV, NPV, sensitivity and specificity were 93.6%, 87.5%, 99.0% and 50.0% respectively. A positive cut-off point of 10% positive thyroid cells in cyclin D1 immunostaining demonstrated sensitivity of 88.5%, specificity of 100%, PPV of 100% and NPV of 53.8% for correctly detecting thyroid malignancy or low-risk neoplasm. The sensitivity and PPV of simplified nuclear score combined with cyclin D1 immunostaining were 93.3% and 100%, respectively. Both specificity and NPV were maintained at high levels (100% and 66.7%, respectively). The diagnostic accuracy of simplified nuclear score combined with cyclin D1 immunostaining in detecting thyroid malignancy/low-risk neoplasm was increased to 94.1% compared to using either of them alone. Conclusions: Combing simplified nuclear score and cyclin D1 immunostaining on FNA cytology specimens can increase the diagnostic accuracy in classifying thyroid nodules of indeterminate cytological categories. Thus, this supplementary approach provides a simple, accurate, and convenient diagnostic method for cytopathologists so that may reduce unnecessary thyroidectomies.

Objective:To study the value of sound touch elastography (STE) linear combined with ultrasound score (US) in the diagnosis of chronic hepatitis B (CHB) liver fibrosis, and to investigate whether their combination can improve the diagnostic efficiency of subdividing the degree of CHB liver fibrosis. Furthermore, a comparison with STE linear combined with the serological model was performed to seek the optimal linear combination model.Methods:A total of 313 subjects were enrolled from September 2018 to December 2021 in Shenzhen Third People′s Hospital Affiliated to Guangdong Medical University, including 259 patients with CHB who had completed liver biopsy and 54 healthy volunteers. CHB patients were divided into liver fibrosis group (F1-F4 group) according to METAVIR classification standard, and healthy volunteers were used as the control group. All subjects underwent liver ultrasound examination, STE and blood biochemical indexes of liver function. The US was performed according to the liver ultrasound examination, and the liver stiffness measurement (LSM) was measured by STE, aspartate aminotransferase and platelet ratio index (APRI) was calculated by blood biochemical index. Fisher discriminant analysis was used to establish the linear combination (LC) diagnostic marker of US and LSM, and the linear combination (LC2) diagnostic marker of LSM and APRI, successively. Spearman rank correlation coefficient was used to analyze the correlations between US, LSM, APRI, LC2, LC and pathological results. The ROC curves of US, LSM, APRI, LC2 and LC for diagnosing CHB liver fibrosis were plotted, and the diagnostic efficiency of above diagnostic markers was evaluated according to the accuracy, sensitivity, specificity and area under the ROC curve (AUC).Results:The formula for the linear combination of US and LSM was LC=0.986 0×US+ 0.166 7×LSM, and LC was highly positively correlated with pathological findings ( rs=0.851, P<0.001), higher than US, LSM, LC2 and APRI ( rs=0.825, 0.775, 0.802, 0.586, all P<0.001). LC showed the best diagnostic efficiency. The AUCs for diagnosing ≥F1, ≥F2, ≥F3 liver fibrosis and =F4 cirrhosis were 0.945, 0.911, 0.954, 0.955, respectively, which superior to the AUCs of US (0.913, 0.879, 0.934 and 0.916, respectively), the AUCs of LSM (0.860, 0.871, 0.934 and 0.952, respectively) and the AUCs of LC2(0.899, 0.883, 0.941, 0.946, respectively). Compared with US, the AUC of LC diagnosis of ≥F1, ≥F2, ≥F3 liver fibrosis and =F4 cirrhosis increased by 3.2%, 3.2%, 2.0% and 3.9%, respectively, with all significant differences ( P<0.05). Compared with LSM, the AUC of LC increased by 8.5%, 4.0%, 2.0% and 0.3%, respectively, with significant difference ( P<0.05) except for stage =F4 cirrhosis.Compared with LC2, the AUC of LC increased by 4.6%, 2.8%, 1.3% and 0.9%, respectively, and there were significant differences in the diagnosis of ≥F1 and ≥F2 liver fibrosis ( P<0.05). Moreover, the overall efficiency of LC2 was not significantly improved than LSM, the difference was not significant ( P>0.05). Conclusions:US, LSM, LC2 and LC can be used to diagnose the degree of CHB liver fibrosis, but LC is better than US or LSM and LC2 alone, especially in the subdivision of mild liver fibrosis, which is a promising new diagnostic marker to subdivide the degree of CHB liver fibrosis.

Objective:To explore the value in differentiating Borrmann Ⅳ type gastric cancer (BT4-GC) from gastric diffuse large B-cell lymphoma (DLBCL) using a nomogram based on CT texture analysis (CTTA) and morphological characteristics.Methods:From June 2011 to December 2020, a total of 60 patients with BT4-GC and 24 patients with DLBCL were retrospectively collected in Nanjing Drum Tower Hospital Clinical College of Nanjing Medical University. Morphological characteristics were evaluated, including major location, long axis range, circumferential range, mucosal line status, and perigastric enlarged lymph nodes. CTTA parameters were calculated using venous CT images with a manual region of interest. The morphological characteristics and CTTA parameters between BT4-GC and DLBCL were compared by χ 2 test, Fisher exact test or Mann-Whitney U test. The multivariate binary logistic regression analysis was used to filter factors into the diagnostic model and construct a nomogram. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of CTTA parameters and the diagnostic model in differentiating BT4-GC from DLBCL. Results:For morphological characteristics, mucosal line status showed a significant difference between BT4-GC and DLBCL (χ 2=12.99, P<0.001). For CTTA parameters, 16 parameters showed significant differences between BT4-GC and DLBCL (all P<0.05). The area under the ROC curve (AUC) of 16 CTTA parameters in differentiating BT4-GC from DLBCL was 0.662-0.833. Percentile 90 showed the highest AUC of 0.833 (95%CI 0.736-0.906). The mucosal line status (OR 4.82, 95%CI 1.21-19.25, P=0.026) and percentile 90 (OR 1.09, 95%CI 1.04-1.15, P=0.001) were brought into the diagnostic model and constructed a nomogram. The AUC of the model in differentiating BT4-GC from DLBCL was 0.898 (95%CI 0.813-0.953), sensitivity was 0.833, and specificity was 0.817. Conclusions:The nomogram based on CTTA percentile 90 and morphological characteristics mucosal line status can effectively distinguish BT4-GC from DLBCL and shows high diagnostic efficacy.

In order to evaluate the efficacy of peroral endoscopic myotomy (POEM) for achalasia, data of 63 patients with achalasia who were treated with POEM in China-Japan Union Hospital of Jilin University from 2017 to 2021 were collected. Postoperative Eckardt score, high-resolution manometry and upper gastrointestinal radiography were compared with preoperative data. The mean age of the 63 patients was 49.0 years, and there were 31 famales. The preoperative Eckardt score was 9 (3), and the postoperative Eckardt score was 2 (2), with significant difference ( V=1 953, P<0.001). The lower esophageal sphincter pressure decreased significantly after operation compared with that before operation [9.90 (3.35) mmHg VS 26.80（13.85）mmHg， V=2 016, P<0.001]. Fifty-three patients (84.1%) had satisfactory curative effects. The incidence of adverse events was 3.2% (2/63). POEM is safe, effective and minimally invasive for the treatment of achalasia.

Objective: To assess the value of cyclin D1 immunocytochemistry combined with a small panel molecular analysis in indeterminate cytological diagnosis of Bethesda category Ⅲ-Ⅴ. Methods: A consecutive cohort of 96 thyroid FNA specimens with indeterminate diagnosis (TBSRTC category Ⅲ-Ⅴ) and available histopathologic follow-up data were collected between December 2018 and December 2021 in Department of Pathology, Beijing Hospital. The cases were evaluated by cyclin D1 immunocytochemistry and molecular testing of BRAF^V600E or a small panel of markers (BRAF, N-RAS, H-RAS, K-RAS and TERT) in the FNA specimens. The identification of the optimal cut-off point of cyclin D1 for the diagnosis of malignancy was evaluated using the receiver operating characteristic (ROC) curves and the assessment of the area under the ROC curve (AUC). The specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) of all these markers were evaluated with the crosstabs and significance was calculated. Results: Ninty-six patients with 96 thyroid nodules were enrolled, including 42 cases of TBSRTC-III, 10 cases of TBSRTC-IV and 44 cases of TBSRTC-V. There were 79 females and 17 males with a median age of 47 years (range, 25 to 75 years). A 7.5% cut-off value for positive cyclin D1 nuclear immunostaining in thyroid cells demonstrated 100% PPV, 57.1% NPV, 81.0% sensitivity and 100% specificity for thyroid malignancy diagnosis. The sensitivity of the BRAF^V600E mutation test or combined with a small panel test alone for thyroid malignancy diagnosis were 65.5% and 69.0% respectively. The sensitivity for thyroid malignancy diagnosis increased to 94.0% and 95.2% respectively when combining the cyclin D1 immunocytochemistry with the molecular test, and the specificities remained 100% and 91.7% respectively.The accuracy of cyclin D1 immunocytochemistry combined with a small panel of molecular test in detecting thyroid malignancy increased to 94.8% compared to using these markers alone. Conclusions: The addition of cyclin D1 immunocytochemistry and a small panel of molecular testing to FNA cytology can increase the sensitivity and NPV of cytology in indeterminate categories, and this supplementary approach provides a simple, accurate and convenient diagnostic method for reducing unnecessary thyroidectomies.

Objective:To explore the effect of MicroRNA 424-5p/Kinesin family member 23(miR-424-5p/KIF23)axis on the malignant phenotype of hepatoma cells and its sensitivity of sorafenib.Methods:Real-time quantitative reverse PCR(qRT-PCR) and/or Western blot were used to detect the expression of miR-424-5p and KIF23 in liver cancer tissues and paracancerous tissues, human hepatocellular carcinoma(HCC) cells HepG2 and normal hepatocyte LO2. HepG2 cells transfected with miR-424-5p mimic and miR-424-5p mimic NC were respectively defined as miR-424-5p mimic group and mimic NC group, HepG2 cells transfected with KIF23 overexpression vector pcDNA3.1-KIF23 or empty vector pcDNA3.1 respectively were defined as OE-KIF23 group and Vector group, and HepG2 cells co-transfected with miR-424-5p mimic and overexpression vector pcDNA3.1-KIF23 were defined as mimic+OE-KIF23 group: The KIF23-3'UTR wild-type vector (KIF23-WT) and the mutant vector (KIF23-MT) were co-transfected with miR-424-5p micic and mimic NC, respectively, and the targeting relationship between miR-424-5p and KIF23 was verified by dual-luciferase reporting experiments. The cell counting Kit-8 (CCK-8) was used to detect HepG2 cell proliferation and sensitivity to sorafenib. Flow cytometry was used to assess apoptosis in HepG2 cells. Transwell and scratch experiments were used to detect HepG2 cell migration and invasion capabilities. Intergroup data were compared using t-tests or analysis of variance. Results:Compared with the paracancerous tissue and normal hepatocytes, miR-424-5p in the HCC tissue and hepatocellular cells was significantly down-regulated (the relative expression was 0.604±0.121, 0.585±0.064), and KIF23 was significantly up-regulated (the relative expression was 5.451±1.834, 2.482±0.545), P<0.05. miR-424-5p mimic can inhibit the proliferation, migration and invasion of HCC cells and promote apoptosis of HCC cells ( P<0.05). Overexpression of KIF23 can promote the proliferation, migration and invasion of HCC cells and inhibit apoptosis of HCC cells ( P<0.05). The luciferase activity of HepG2 cells in the mimic and KIF23-WT co-transfection groups was significantly reduced compared with HepG2 cells in the mimic NC and KIF23-WT co-transfection groups (the relative fluorescence intensities were 3.668±0.091 and 2.629±0.056, respectively, P<0.05),however, there was no significant comparison between the luciferase activity of cells in the mimic and KIF23-MT co-transfection groups compared with those in the mimic NC and KIF23-MT co-transfection groups. miR-424-5p mimic can reverse the role of overexpression of KIF23 in promoting the ability of HCC cells to proliferate, migrate and invade ( P<0.05). The inhibition rates of sorafenib on HepG2 cells in the mimic+OE-KIF23 group and the OE-KIF23 group were 47.491%±3.863% and 36.246%±6.063% ( t=3.027, P<0.05). Conclusion:miR-424-5p can inhibit the proliferation, migration and invasion of HCC cells and can increase the sensitivity of HCC cells to sorafenib by targeting the expression level of KIF23.

Objective:To investigate the clinical efficacy of plasma exchange combined with dual plasma molecular adsorption system (PE+ DPMAS) in treating patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 114 HBV-ACLF patients admitted to The Affiliated Hospital of Southwest Medical University in Luzhou City and treated with PE+ DPMAS from June 2014 to January 2018 were included. According to different basis of liver diseases, there were type A, type B and type C. The laboratory data and model for end-stage liver disease (MELD) of patients before PE+ DPMAS and 48 h after treatment, and the prognosis of patients at 90 d were retrospectively analyzed. Independent sample t test, paired sample t test, nonparametric test, variance analysis and chi-square test were used for statistical analysis. Results:The clinical stages among patients with type A (22 cases), type B (39 cases) and type C (53 cases) were mainly early (seven, 17, 22 cases) and mid-stages (eight, 14, 20 cases). Before PE+ DPMAS, alanine aminotransferase (ALT), prealbumin (pAlb), albumin (Alb), creatinine (Cr), total bilirubin (TBil), prothrombin time (PT), international normalized ratio (INR), prothrombin activity (PTA), and MELD were all not statistically different among the patients in the three groups (all P>0.05). After PE+ DPMAS treatment, ALT, TBil, PT, INR, MELD, pAlb, Alb, and PTA in patients with type A were statistically different compared with those before treatment ( Z=5.104, t=5.555, 4.974, 4.481, 7.984, -5.396, -2.784 and -6.752, respectively, all P<0.05). ALT, TBil, PT, INR and MELD in patients with type B were significantly decreased, while pAlb and PTA were significantly increased after treatment ( Z=-5.428, t=4.867, 4.405, 4.179, 6.186, -6.290 and -4.533, respectively, all P<0.01). ALT, pAlb and TBil in patients with type C after PE+ DPMAS treatment were significantly different from those before treatment ( Z=-5.723, t=-2.525 and 2.462, respectively, all P<0.05). There was no statistically significant difference in Cr of the three groups before and after treatment (all P>0.05). The patients with type A had the shortest hospital stay ((17.95±5.92) d), while the patients with type C had the longest stay ((25.77±7.02) d). The hospital stay of patients with type B was (21.79±6.72) d. The difference was statistically significant ( F=11.317, P<0.01). After 90 d follow-up, four patients (18.18%) with type A died, nine patients (23.08%) with type B died, and 25 patients (47.17%)with type C died. The difference was statistically significant ( χ2=8.615, P=0.013). Conclusion:HBV-ACLF patients with type A and type B have better prognosis after PE+ DPMAS treatment compared to patients with type C who are in the decompensated stage of liver cirrhosis.

【Objective】 To investigate the distribution characteristics of Rh blood group antigen phenotypes, haplotypes and irregular antibodies between patients in our hospital and local blood donors, so as to ensure safe and effective blood transfusion and improve the rationality and scientificity of clinical blood transfusion. 【Methods】 A total of 113 326 blood samples, from hospitalized patients in our hospital and local blood donors from October 2015 to March 2020, were subjected to Rh antigen typing and irregular antibody detection. The frequency of Rh phenotypes, haplotypes, and irregular antibodies were retrospectively analyzed and calculated. Chi square test was used to compare the data among different population groups. Rh antigen typing and irregular antibody detection were completed using the automatic blood group analyzer. 【Results】 The prevalence of negative RhD was 0.36% (408/113 326). The most prevalent Rh phenotype was DCCee [40.69%(46 112/ 113 326)] followed by DCcEe [36.82%(41 727/ 113 326)]. Anti-E was the most common irregular antibody, accounting for [0.26%(295/ 113 326)], and DCe [62.51%(70 840/ 113 326)] was the most common haplotype. The most common Rh phenotypes and haplotypes in Caucasians in Germany, North Indian and North African were DCcee, DCCee and Dccee, while DCe, DCe and Dce, respectively. 【Conclusion】 The distribution characteristics of Rh phenotypes, haplotypes and irregular antibodies of patients in our hospital and local blood donors were in line with the distribution characteristics of the population in northern China. Corresponding plans concerning blood storage and collection, as well as the establishment of Rh blood type registry should be carried to effectively ensure the safety, rationality and accuracy of clinical blood transfusion.
