ObjectiveTo investigate the influencing factors for hepatic hydrothorax (HH) before intervention for primary hepatic carcinoma (PHC), and to construct and assess the nomogram risk prediction model. MethodsA retrospective analysis was performed for the clinical data of 353 hospitalized patients who attended the Third People’s Hospital of Kunming for the first time from October 2012 to October 2021 and there diagnosed with PHC, and according to the presence or absence of HH, they were divided into HH group with 153 patients and non-HH group with 200 patients. General data and the data of initial clinical testing after admission were collected from all PHC patients. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. After the multicollinearity test was performed for the variables with statistical significance determined by the univariate analysis, the multivariate Logistic regression analysis was used to identify independent influencing factors. The “rms” software package was used to construct a nomogram risk prediction model, and the Hosmer-Lemeshow test and the receiver operating characteristic (ROC) curve were used to assess the risk prediction model; the “Calibration Curves” software package was used to plot the calibration curve, and the “rmda” software package was used to plot the clinical decision curve and the clinical impact curve. ResultsAmong the 353 patients with PHC, there were 153 patients with HH, with a prevalence rate of 43.34%. Child-Pugh class B (odds ratio [OR]=2.652, 95% confidence interval [CI]: 1.050 — 6.698, P=0.039), Child-Pugh class C (OR=7.963, 95%CI: 1.046 — 60.632, P=0.045), total protein (OR=0.947, 95%CI: 0.914 — 0.981, P=0.003), high-sensitivity C-reactive protein (OR=1.007, 95%CI: 1.001 — 1.014, P=0.025), and interleukin-2 (OR=0.801, 95%CI: 0.653 — 0.981, P=0.032) were independent influencing factors for HH before PHC intervention, and a nomogram risk prediction model was established based on these factors. The Hosmer-Lemeshow test showed that the model had a good degree of fitting (χ2=5.006, P=0.757), with an area under the ROC curve of 0.752 (95%CI: 0.701 — 0.803), a sensitivity of 78.40%, and a specificity of 63.50%. The calibration curve showed that the model had good consistency in predicting HH before PHC intervention, and the clinical decision curve and the clinical impact curve showed that the model had good clinical practicability within a certain threshold range. ConclusionChild-Pugh class, total protein, interleukin-2, and high-sensitivity C-reactive protein are independent influencing factors for developing HH before PHC intervention, and the nomogram model established based on these factors can effectively predict the risk of developing HH.

ObjectiveTo investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis, and to establish a predictive model. MethodsA total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January, 2019 to December, 2022 were enrolled, among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group, and 154 patients without recompensation were enrolled as control group. Related clinical data were collected, and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis, and the receiver operating characteristic (ROC) curve was used to assess the predictive performance of the model. ResultsAmong the 217 patients with decompensated hepatitis C cirrhosis, 63 (29.03%) had recompensation. There were significant differences between the recompensation group and the control group in HIV history (χ2=4.566, P=0.034), history of partial splenic embolism (χ2=6.687, P=0.014), Child-Pugh classification (χ2=11.978, P=0.003), grade of ascites (χ2=14.229, P<0.001), albumin (t=4.063, P<0.001), prealbumin (Z=-3.077, P=0.002), high-density lipoprotein (t=2.854, P=0.011), high-sensitivity C-reactive protein (Z=-2.447, P=0.014), prothrombin time (Z=-2.441, P=0.015), carcinoembryonic antigen (Z=-2.113, P=0.035), alpha-fetoprotein (AFP) (Z=-2.063, P=0.039), CA125 (Z=-2.270, P=0.023), TT3 (Z=-3.304, P<0.001), TT4 (Z=-2.221, P=0.026), CD45+ (Z=-2.278, P=0.023), interleukin-5 (Z=-2.845, P=0.004), tumor necrosis factor-α (Z=-2.176, P=0.030), and portal vein width (Z=-5.283, P=0.005). The multivariate analysis showed that history of partial splenic embolism (odds ratio [OR]=3.064, P=0.049), HIV history (OR=0.195, P=0.027), a small amount of ascites (OR=3.390, P=0.017), AFP (OR=1.003, P=0.004), and portal vein width (OR=0.600, P<0.001) were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history, grade of ascites, history of partial splenic embolism, AFP, portal vein width, and the combined predictive model of these indices had an area under the ROC curve of 0.556, 0.641, 0.560, 0.589, 0.745, and 0.817, respectively. ConclusionFor patients with decompensated hepatitis C cirrhosis, those with a history of partial splenic embolism, a small amount of ascites, and an increase in AFP level are more likely to experience recompensation, while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation.

ObjectiveTo investigate the value of noninvasive imaging detection (FibroScan), two serological models of gamma-glutamyl transpeptidase-to-platelet ratio (GPR) score and S index, and two inflammatory factors of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in predicting liver fibrosis in patients with HBeAg-positive chronic hepatitis B (CHB), as well as the consistency of liver biopsy in pathological staging, and to provide early warning for early intervention of CHB. MethodsA retrospective analysis was performed for 131 HBeAg-positive CHB patients who underwent liver biopsy in The Third People’s Hospital of Kunming from January 2019 to December 2023. The results of liver biopsy were collected from all patients, and related examinations were performed before liver biopsy, including total bilirubin, alanine aminotransferase, platelet count, gamma-glutamyl transpeptidase, albumin, IL-6, TNF-α, liver stiffness measurement (LSM), and abdominal ultrasound. An analysis of variance was used for comparison of normally distributed continuous data between groups, and the Kruskal-Wallis H 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. A Kappa analysis was used to investigate the consistency between LSM noninvasive histological staging and pathological staging based on liver biopsy, and the Spearman analysis was used to investigate the correlation between each variable and FibroScan in the diagnosis of liver fibrosis stage. The Logistic regression analysis was used to construct joint predictive factors. The receiver operating characteristic (ROC) curve was used to evaluate the value of each indicator alone and the joint predictive model in the diagnosis of liver fibrosis, and the Delong test was used for comparison of the area under the ROC curve (AUC). ResultsIn the consistency check, inflammation degree based on liver biopsy had a Kappa value of 0.807 (P<0.001), and liver fibrosis degree based on liver biopsy had a Kappa value of 0.827 (P<0.001), suggesting that FibroScan noninvasive histological staging and liver biopsy showed good consistency in assessing inflammation degree and liver fibrosis stage. Age was positively correlated with LSM, GPR score, S index, IL-6, and TNF-α (all P<0.05), and GPR score, S index, IL-6, and TNF-α were positively correlated with LSM (all P<0.05). GPR score, S index, IL-6, and TNF-α were all independent risk factors for diagnosing significant liver fibrosis (≥S2) and progressive liver fibrosis (≥S3) (all P<0.05). As for each indicator alone, GPR score had the highest value in the diagnosis of significant liver fibrosis (≥S2), followed by S index, IL-6, and TNF-α, while S index had the highest value in the diagnosis of progressive liver fibrosis (≥S3), followed by GPR score, TNF-α, and IL-6. The joint model had a higher predictive value than each indicator alone (all P<0.05). ConclusionThere is a good consistency between FibroScan noninvasive histological staging and pathological staging based on liver biopsy. GPR score, S index, IL-6, and TNF-α are independent risk factors for evaluating different degree of liver fibrosis in CHB, and the combined prediction model established by them can better diagnose liver fibrosis.

ObjectiveTo investigate the therapeutic efficacy, influencing factors, and safety of a treatment regimen based on coblopasvir hydrochloride capsules/sofosbuvir tablets in patients with chronic hepatitis C virus (HCV) infection in a real-world setting. MethodsA total of 253 patients who attended The Third People’s Hospital of Kunming from September 1, 2021 to May 31, 2024 were enrolled, among whom there were 86 patients with compensated liver cirrhosis (CLC group) and 167 patients with chronic hepatitis C (CHC group). The patients were treated with coblopasvir hydrochloride capsules (60 mg)/sofosbuvir tablets (400 mg) with or without ribavirin tablets for 12 weeks, and they were followed up for 12 weeks after drug withdrawal. The primary outcome measures were the rate of sustained virologic response at week 12 after treatment (SVR12) and safety, and the secondary outcome measures were the changes in liver function, renal function, blood routine, and liver stiffness measurements (LSM) after 4 weeks of treatment, after 12 weeks of treatment, and at 12 weeks after drug withdrawal. The independent-samples t test and the Mann-Whitney U test were used for comparison of continuous data between two groups, and the Friedman test was used for comparison between multiple groups, while the Bonferroni method was used for paired comparison within each group; the chi-square test was used for comparison of categorical data between two groups. The Logistic analysis was used to investigate related influencing factors. ResultsThe 253 patients with chronic HCV infection had a mean age of 49.38±8.65 years, and there were 151 male patients (59.7%). Of all patients, 33.99% (86/253) had liver cirrhosis, 25.69% (65/253) had hypertension, 10.67% (27/253) had HIV infection, 8.70% (22/253) had diabetes, 3.95% (10/253) had liver cancer, 1.98% (5/253) had chronic hepatitis B, and 7.91% (20/253) were treatment-experienced patients. As for genotype distribution, 2.77% (7/253) had genotype 1, 12.65% (32/253) had genotype 2, 66.01% (167/253) had genotype 3, 16.60% (42/253) had genotype 6, and 1.98% (5/253) had unknown genotype. The patients had an overall SVR12 rate of 92.09%, with an SVR12 rate of 93.02% in the CLC group and 91.02% in the CHC group. The multivariate logistic regression analysis showed that age (odds ratio [OR]=1.086, 95% confidence interval [CI]: 1.007 — 1.170, P=0.032) and HCC (OR=9.178, 95%CI: 1.722 — 48.912, P=0.009) were independent influencing factors for sustained virologic response. Compared with baseline data, the CLC group had significant reductions in alanine aminotransferase (ALT) (χ2=107.103, P0.05), aspartate aminotransferase (AST) (χ2=90.602, P0.05), and LSM (χ2=42.235, P0.05) after 12 weeks of treatment, while the CHC group had significant reductions in total bilirubin (χ2=15.113, P0.05), ALT (χ2=202.237, P0.05), AST (χ2=161.193, P0.05), and LSM (χ2=37.606, P0.05). The incidence rate of serious adverse events was 1.58%, and none of the patients withdrew from drug therapy; the patients with such events were relieved after active symptomatic treatment. The incidence rate of all adverse events was 23.72%, among which fatigue (17.39%) and nausea (2.37%) were the most common adverse events, and these events often disappeared within 2 weeks or were gradually relieved after symptomatic treatment. ConclusionCoblopasvir hydrochloride capsules/sofosbuvir tablets with or without ribavirin tablets has good efficacy and safety in the treatment of chronic HCV infection.

Objective To understand the basic information of the number, classification, and distribution of radiation work units in non-medical institutions in Shanxi Province, China, and to analyze the status quo of health management and radiation protection measures for radiation workers, so as to provide a scientific basis for occupational exposure protection in non-medical radiation work units and better protect the occupational health rights and interests of radiation workers. Methods A questionnaire survey was conducted to investigate some non-medical institutions in Shanxi Province. On-site testing was carried out to determine the risk factors for radioactive occupational diseases in the selected non-medical institutions. Results In 220 non-medical institutions, there were 340 radiation devices and 2284 radioactive sources. The rate of individual dose monitoring was 92.7% and the rate of occupational health examination was 87.2%. These devices were equipped with 325 detection instruments for radiation protection, 1316 personal protective equipment, and 730 personal dose alarms. Radiation occupational disease risk factors were investigated in 101 institutions. Conclusion The occupational health management of radiation workers in non-medical institutions in Shanxi Province is generally in line with the national standards. However, there is still a big gap with the level of occupational health management in medical institutions. The health administration departments should clarify the management measures for non-medical institutions and strengthen their supervision and management functions.
