Objective To investigate the value of the hepatocellular carcinoma (HCC) risk model REAL-B score in predicting the risk of HCC in chronic hepatitis B (CHB) patients receiving antiviral therapy in comparison with mPAGE-B, aMAP and PAGE-B scores. Methods A retrospective analysis was performed for the clinical data of 1160 CHB patients who received entecavir or tenofovir treatment for more than 1 year from January 2013 to December 2015 in Tianjin Second Peolple's Hospital, and the events of HCC were recorded. The area under the ROC curve (AUC) was used to evaluate the value of REAL-B, mPAGE-B, aMAP, and PAGE-B scores in predicting HCC. The Kaplan-Meier method was used to evaluate the cumulative incidence rate of HCC at different time points, and the log-rank test was used to compare the incidence rate of HCC between the groups with different scores. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. Results Among the 1160 CHB patients, 108 (9.8%) progressed to HCC within a median follow-up time of 5.3 (5.0-6.3) years. REAL-B score had an AUC of 0.848 (95% confidence interval [ CI ]: 0.816-0.880) in predicting the onset of HCC within 5 years, followed by aMAP score (AUC=0.823, 95% CI : 0.786-0.860), mPAGE-B score (AUC=0.822, 95% CI : 0.788-0.857), and PAGE-B scores (AUC=0.780, 95% CI : 0.736-0.824). The 5-year cumulative incidence rate of HCC was 0.8% in the low-risk group (with a REAL-B score of 0-3 points), which was significantly lower than the incidence rate of 11.8% in the medium-risk group (with a REAL-B score of 4-7 points) and 35.6% with the high-risk group (with a REAL-B score of 8-13 points) ( P < 0.05). In the low-risk group, REAL-B score had a negative predictive value of 100% and 99.67%, respectively, in predicting HCC within 3 and 5 years. Conclusion REAL-B score accurately predicts the risk of HCC in CHB patients receiving antiviral therapy, with a better predictive value than the other risk models within 3 years of antiviral therapy.

Objective To investigate the value of neutrophil-to-lymphocyte ratio (NLR), red blood cell distribution width-to-lymphocyte ratio (RLR), and lymphocyte-to-monocyte ratio (LMR) in predicting the prognosis of early small hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA). Methods A retrospective analysis was performed for 132 patients newly diagnosed with early HCC who underwent RFA in Tianjin Second People's Hospital from September 2011 to December 2020. Preoperative data were collected and the patients were followed up to observe recurrence and overall survival (OS). The X-tile tool was used to determine the optimal cut-off values of NLR, RLR, and LMR based on 5-year survival rate and recurrence-free survival (RFS) rate, and then the patients were divided into N-R-L 0 group with 92 patients, N-R-L 1 group with 29 patients, and N-R-L 2 group with 11 patients. The chi-square test was used for comparison of categorical data between the three groups. The Kaplan-Meier method was used to plot the survival curve, and the log-rank test was used to compare RFS and OS rates between groups. The factors with statistical significance in the log-rank test were included in the multivariate Cox regression analysis to determine the risk factors for RFS and OS rates. Results There were significant differences in Child-Pugh class and albumin between the N-R-L 0, N-R-L 1, and N-R-L 2 groups ( χ 2 2=10.992 and 5.699, both P < 0.05). The 1-, 3-, and 5-year OS rates of the three groups were 100%/96.3%/90.7%, 96.6%/60.4%/41.3%, and 81.8%/46.8%/15.6%, respectively ( χ 2 =38.46, P < 0.000 1), and the 1-, 3-, and 5-year RFS rates of the three groups were 76.9%/52.5%/33.3%, 42.9%/13.1%/0, and 11.1%/0/0, respectively ( χ 2 =35.345, P < 0.000 1). The multivariate Cox regression analysis showed that tumor diameter ≥ 2 cm (hazard ratio[ HR ]=2.10, 95% confidence interval[ CI ]: 1.28-3.43, P =0.003; HR =3.67, 95% CI : 1.58-8.52, P =0.002), N-R-L score of 1 point ( HR =3.14, 95% CI : 1.81-5.46, P < 0.000 1; HR =8.27, 95% CI : 3.15-21.71, P < 0.000 1), and N-R-L score of 2 points ( HR =2.61, 95% CI : 1.06-6.42, P =0.037; HR =14.59, 95% CI : 3.96-53.78, P < 0.000 1) were independent predictive factors for RFS and OS. Conclusion N-R-L, a systemic inflammatory response marker composed of NLR, RLR, and LMR, is an independent risk factor for recurrence and survival of early small HCC after RFA, and it can be used as a useful noninvasive biomarker in combination with tumor features to predict the recurrence and survival of early HCC after RFA.

Objective:To investigate the clinical, skeletal muscle pathological, and genetic characteristics of fatal infantile hypertonic myofibrillar myopathy (FIHMM).Methods:The clinical manifestations, laboratory assessments data and gene sequencing results of 10 patients diagnosed with FIHMM in Shenzhen Children′s Hospital from February 2017 to April 2021 were retrospectively analyzed.Magnetic resonance imaging (MRI) of both musculoskeletal system and the brain, and electromyogram (EMG) were performed in 3 cases, while muscle biopsy was performed in 2 cases.Results:Among these 10 cases, 1 case was from Northeast China and 1 case from East China, while the rest 8 cases were from South China.Eight of the 10 patients were male, and the other 2 cases were female.They were all born normal and not related to each other.The age of onset varied from 2 to 12 months.The main clinical manifestations for all the patients were progressive rigidity of the rectus abdominis (8 cases), neck muscles (7 cases), rectus abdominis (2 cases) and intercostal muscles (1 case), resulting in respiratory failure.Mildly to moderately elevated serum creatine kinase level was detected (436-5 804 IU/L) (reference range: 24-229 IU/L). Complex repetitive discharges can be seen in the EMG, without any myotonic potential.Muscle fiber degeneration, necrosis, and vacuolar degeneration were noted in the histopathological examination of the vastus lateralis and rectus abdominis.An abnormal red granular deposit was observed in a portion of the field of the modified Gomory Trichrome staining.Immunohistochemistry showed substantial deposition of desmin.Under the electron microscopy, the sarcomere structure of the muscle fibers was seriously disordered, with the destruction of Z-bands and the presence of granular deposits.The whole-exome sequencing identified the same homozygous variation c. 3G>A, p.Met1? of CRYAB gene in all the patients, but heterozygous variation in their parents. Conclusions:Axial muscles involvement, such as rectus abdominis rigidity, is the main clinical characteristic of FIHMM.c.3G>A, p.Met1? mutation in the CRYAB gene is a hotspot mutation in Chinese children.

Objective:To explore the clinical features of decompensated liver cirrhosis patients with acute kidney injury (AKI) progressing to chronic kidney disease (CKD) and its impact on prognosis.Methods:From January 2015 to July 2019, at Tianjin Second People′s Hospital, the general data and laboratory test results of 346 hospitalized patients with decompensated liver cirrhosis were retrospectively analyzed. The patients were followed up for 12 months. Univariate analysis and multivariate logistic regression analysis were used to analyze the risk factors of AKI and CKD. Kaplan-Meier method was used for survival analysis. The independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:A total of 128 patients with decompensated liver cirrhosis developed AKI, and 25 of them developed into CKD. Univariate analysis showed that age, hypertension, complications of liver cirrhosis infection, ascites and hepatic encephalopathy, acute-on-chronic liver failure, Child-Turcotte-Pugh score of liver function, baseline serum creatinine, post-admission serum creatinine, serum sodium, white blood cell count, total cholesterol, triglyceride, high-density lipoprotein, total bilirubin, albumin, international normalized ratio (INR) and prothrombin time activity were risk factors of AKI in patients with decompensated liver cirrhosis ( t=3.822, χ2=12.534, 26.761, 5.035, 3.894 and 26.101, U=7 004.500, 9 132.500, 5 925.000, 10 144.000, 10 717.500, 10 827.000, 10 912.000, 5 741.500, 10 017.000, 10 187.500, 11 680.500 and 11 321.500, all P<0.05). The risk factors of AKI progressing to CKD in decompensated liver cirrhosis included the etiology of liver cirrhosis, hypertension, baseline serum creatinine, serum creatinine at the time of diagnosis of AKI, total cholesterol, INR, AKI etiology and AKI classification ( χ2=13.153 and 9.144, U=353.000, 337.000, 576.500 and 481.000, χ2=9.501 and 17.801, all P<0.05). The results of multivariate logistic regression analysis showed that the independent risk factors of AKI progressing to CKD in decompensated liver cirrhosis included baseline serum creatinine (odds ratio ( OR)=1.066, 95% confidence interval ( CI) 1.020 to 1.114, P=0.005) and AKI classification ( OR=6.086, 95% CI 1.828 to 20.260, P=0.003). The Kaplan-Meier survival curve showing that after following up for 12 months, the survival rate of patients with decompensated liver cirrhosis patients who progressed to CKD from AKI was lower than that of patients who did not developed into CKD (52.0%, 13/25 vs. 86.4%, 51/59), and the difference was statistically significant ( χ2=11.482, P=0.001). Conclusion:The transition from AKI into CKD is common in patients with liver cirrhosis, which affects the clinical prognosis and reduces the survival rate.

Objective:To investigate the factors affecting the application of systemic glucocorticoids in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with carbon dioxide (CO 2) retention, and to guide the formulation of a strategy to reduce systemic glucocorticoid exposure. Methods:The AECOPD patients with CO 2 retention admitted to the Ningde Municipal Hospital of Fujian Medical University from January 2017 to December 2019 were enrolled. The general information, past history, times of acute exacerbations within 1 year, pneumonia on admission, causes of COPD, heart failure, blood gas analysis, eosinophil count (EOS), albumin (Alb) and apolipoprotein E (ApoE) levels, exhaled nitric oxide (FeNO) level, inhaled glucocorticoid and non-invasive mechanical ventilation treatment at acute exacerbation were collected. The patients were divided into recommended dosage group (exposure levels in the recommended dosage range, cumulative prednisone dosage ≤ 200 mg) and exceeded group (exposure levels exceeded the recommended dose, cumulative prednisone dosage > 200 mg) according to cumulative systemic glucocorticoid exposure dosage of the patients during hospitalization. The clinical data of patients between the two groups were compared, and possible factors with P < 0.1 in univariate analysis were included in multivariate Logistic regression analysis to screen the related factors of systemic glucocorticoid exposure level in AECOPD patients with CO 2 retention. Results:According to the order of hospitalization, 151 AECOPD patients with CO 2 retention were enrolled, 8 patients were excluded, and 143 patients were enrolled in the analysis. Of the 143 patients, 68 received the recommended dose of systemic glucocorticoid, and 75 received excessive systemic glucocorticoid. Age, percentage of forced expiratory volume in 1 second (FEV1%) at stable phase, frequency of acute exacerbation within 1 year, heart failure ratio, oxygen index (PaO 2/FiO 2), arterial partial pressure of carbon dioxide (PaCO 2), serum EOS and ApoE levels at admission, the ratio of aerosolized inhaled glucocorticoids and non-invasive mechanical ventilation showed statistical differences between the two groups. Multivariate Logistic regression analysis showed that related factors affecting systemic glucocorticoid exposure levels of AECOPD patients with CO 2 retention were FEV1% at stable phase [odds ratio ( OR) = 0.957, 95% confidence interval (95% CI) was 0.921-0.994, P = 0.023], acute exacerbation frequency within 1 year ( OR = 1.530, 95% CI was 1.121-2.088, P = 0.007), heart failure ( OR = 3.022, 95% CI was 1.263-7.231, P = 0.013), PaCO 2 ( OR = 1.062, 95% CI was 1.010-1.115, P = 0.018) and EOS at admission ( OR = 0.103, 95% CI was 0.016-0.684, P = 0.019), aerosolized inhaled glucocorticoids ( OR = 0.337, 95% CI was 0.145-0.783, P = 0.011) and non-invasive mechanical ventilation at acute exacerbation ( OR = 0.422, 95% CI was 0.188-0.948, P = 0.037), of which high FEV1% at stable phase, high EOS at admission, aerosolized inhaled glucocorticoid and non-invasive mechanical ventilation at acute exacerbation were protective factors, while high frequency of acute exacerbation within 1 year, heart failure and high PaCO 2 were risk factors. Conclusions:For AECOPD patients with CO 2 retention, high FEV1% at stable phase, high EOS level at admission, aerosolized inhaled glucocorticoid and non-invasive mechanical ventilation at acute exacerbation can reduce systemic glucocorticoid exposure. In addition, high frequency of acute exacerbation within 1 year, heart failure, and high PaCO 2 can increase systemic glucocorticoid exposure.

Objective:This study compares the magnetic resonance imaging (MRI) appearance of two types of breast tissue markers to investigate the appropriate clinical application of the markers.Methods:Breast MRI of 69 patients (78 masses) with breast tissue markers had been placed were analyzed retrospectively from November 2015 to August 2018 in our hospital. The sizes and shapes of breast tissue markers were assessed in axial fat-suppressed T2-weighted images, T1-weighted images and contrast-enhanced T1-weighed images.Results:The length of the coil nickel-free stainless steel markers were greater than ribbon titanium markers, with statistical difference in fat-suppressed T2-weighted images ( P=0.039). In contrast-enhanced T1-weighted images, all coil nickel-free stainless steel markers showed >6 mm diameter and round shape, and ribbon titanium markers showed >6 mm diameter ( n=20) or ≤6 mm diameter ( n=8), and round ( n=20), dot ( n=7) or band ( n=1) shapes. The categories of sizes and shapes in two types of breast tissue markers both had statistical significance ( P<0.001, P<0.001). Conclusions:Small breast lesions with breast tissue markers are not suitable for MRI evaluation. The artifact of ribbon titanium markers is smaller than coil nickel-free stainless steel markers, so they have less impact for lesions. The choice of the breast tissue markers and image evaluation methods should depend on the different clinical conditions.

Objective To study the predictive value of magnetic resonance imaging (MRI),positron emission computed tomography (PET)and PET/MRI coregistration in intractable epilepsy of children.Methods A retrospec-tively analysis was performed based on the surgery data at the Department of Children Epilepsy Center of Peking Univer-sity First Hospital from September 2015 to March 2016.The clinical data,surgery and follow－up study data,interictal and ictal electroencephalogram,MRI,PET and PET/MRI coregistration data were collected.By comparison with the epi-leptogenic zone designed by pre－surgical workup,the accuracy of MRI,PET and PET/MRI coregistration in detecting lesion was assessed.In the patients who had no seizure during≥1 year follow－up,their sensitivity,specificity,positive predictive value,negative predictive value of MRI,PET and PET/MRI coregistration were calculated.Results (1)A total of 62 patients underwent surgery,30 boys and 32 girls. The average age on epilepsy onset was 2. 50 years (2 days－11.70 years),and average age on surgery was 5.10 years old(0.75－15.60 years old).(2)Surgical treat-ment of 62 cases included the resection of the focal or lobar (32 cases,51.6%),and the multilobar (16 cases, 25. 8%).Hemispherotomy was done in 14 cases (22.6%).During ≥1 year follow－up,seizure outcome was Engel class Ⅰ in 57 cases (91.9%)out of the 62 patients,Engel classⅡto Engel classⅣin 1 case,3 cases,and 1 case, respectively.(3)Referred to epileptogenic zone designed by presurgical workup,MRI represented 64.5%(40/62 ca-ses)results with accordance,PET and PET/MRI coregistration was 72.5%(45/62 cases)and 85.5%(53/62 cases), respectively,and the difference was significant(χ2＝7.25,P＝0.03).(4)Based on the patients of Engel class Ⅰ, their sensitivity and specificity were 66.7%,60.0% in MRI,75.4%,60.0% in PET %,and 85.9%,80.0% in PET/MRI coregistration,respectively.(5)There were 11 ＂non－lesion＂ cases of all focal cortical dysplasia in patholo-gy,and subtle structural abnormalities were de tected in 9 cases by reviewing MRI.Conclusions PET/MRI coregistra-tion can improve lesion detection of intractable epilepsy in children.

Objective To discuss the influence of microRNA(miR)-155/miR-21 on toll-like receptor 4 (TLR4) in children with sepsis.Methods Fifty children with sepsis who were hospita-lized in Pediatric Intensive Care Unit,Shenzhen Children's Hospital,were enrolled in the study,and 15 healthy children at the same age were selected as healthy control group.Expression levels of TLR4 protein and human leukocyte antigen(HLA)-DR in CD14 + monocytes (MC) were detected by using flow cytometry,and sepsis patients were divided into 2 groups according to whether they exceeded the value of HLA-DR by 30％ or not.Expression level of programmed cell death factor 4 (PDCDM) and inositol phosphatases 1 containing SH2 (SHIP1) were detected at the same time.MC were separated by CD14 + immune magnetic bead,and expression level of miR-155,miR-21 and tumor necrosis factor-α (TNF-α),interleukin-10 (IL-10) mRNA in CD14 + MC were detected by using real-time fluorescent quantitative PCR.Results Sepsis group consisted of 27 male and 23 female,and their ages were (2.34 ± 0.79) years old,among whom 9 patients died.There were 36 patients in the HLA-DR increase group and 14 patients in the HLA-DR decrease group.Expressions ofTLR4(2.33±0.90),miR-155[(7.19±3.75) ×10 3] and TNF-α[(21.98±14.15) ×10-2 pg/L] in CD14 + MC were higher in the HLA-DR increase group than those in the HLA-DR decrease group [1.24±0.60,(4.83 ±1.17) × 10-3,(14.18±5.45) ×10-2 μg/L] and healthy control group[1.57±0.55,(3.99 ± 1.29) × 10-3,(1.61 ± 0.84) × 10 2 pg/L],and the differences were statistically significant(F =11.943,7.583,18.538,all P ＜0.05),while the expressions of miR-21 (12.10 ±5.66),IL-10[(29.74 ± 12.55) × 10-4 μg/L] in CD14 + MC were lower in the HLA-DR increase group than those in the HLA-DR decrease group[4.68 ± 2.07,(12.50 ± 5.73) × 10-4 μg/L] and healthy control group [2.39 ± 0.86,(2.04 ± 0.92) × 10-4 μg/L],and the differences were statistically significant(F =41.673,54.991,all P ＜ 0.05).The levels of SH1P1 and PDCD4 decreased in sepsis compared with healthy control group[0.70 ±0.36)vs.(1.59 ±0.48);(1.55 ±0.56) vs.(3.01 ±0.70)],and the differences were statistically significant (t =7.682,8.339,all P ＜ 0.05),but SHIP1 decreased more significantly in the HLA-DR increase group than that in the HLA-DR decrease group [(0.60 ± 0.34) vs.(0.97 ± 0.26)],and the difference was statistically significant (F =39.214,P ＜ 0.05).PDCD4 decreased more significantly in the HLA-DR decrease group than that in the HLA-DR increase group (0.94 ±0.19 vs.1.79 ±0.47),the difference was statistically significant(F =65.367,P ＜ 0.05).Conclusions Regulation imbalance of miR-155/miR-21 may be one of the reasons for abnormal expression of TLR4 in children with sepsis,and it plays a role in enlarged or inhibited expression of TLR4 in the sepsis process which results in different immune status in sepsis patients.
