Objective o evaluate the association between IL-28B ( rs12979860 ) polymorphism andantiviraltherapeutic effectbydetecting the genotype of interleukin-28B( IL-28 B) in patients with hepatitis C ( HCV ) .Methods Of total 1153 HCV patients, 303 diagnosed with CHC had been treated with pegylated interferon plus ribavirin for 24-48 weeks.IL-28B ( rs12979860 ) was genotyped by two-color fluorescent TaqMan assay.Results Among 1153 patients, CC, CT and TT genotype frequencies of IL-28B rs12979860 are 83.26%, 16.22%and 0.52%respectively.The results of HCV genotypingof 580 in 1153 cases, the frequencies of 1b, 2a and their non-1b/2a type are 63.45%, 35.00%and 1.55%respectively;In 303 CHC patients with clear medical history, the proportion of SVR was71.98% in patients with CC genotype and 16.90%in those with either the CT or TT genotypes.Logistic regression model was adopted to analyze the association of rs12979860 with SVR while adjusting for age, gender, viral load and HCV GT factors.Populations carrying combined genotype ( CT +TT) are making it harder to get SVR compared with those with CC genotype (OR, 95%CI:11.10,5.35-23.04;P<0.000 1).The percentages of SVR in HVC patients with 1b and 2a genotypeare 48.02% and 81.19% respectively.there is a statistically significant difference between these subgroups (χ2 =30.639,P<0.000 1).Conclusion IL-28B rs12979860 genotype is closely related to SVR in CHCpatients.Patients with CC genotype have a higher virus sustained response rate than those carrying CT or TT genotype.The SNP , rs12979860, might be applied as a predictor of clinical antiviral efficacy in the furture.

Objective:To construct and validate a risk prediction model for immune checkpoint inhibitor-associated pneumonia (CIP) using machine learning algorithms and the nomogram, aiming to provide an accurate and intuitive method to assist nurses in screening people at high risk of developing CIP.Methods:This was a retrospective case -control study. A total of 230 oncology patients treated with immune checkpoint inhibitors attending Zhujiang Hospital of Southern Medical University from January 2019 to February 2022 were collected using the hospital's electronic medical record system. The prediction models were built using five machine learning algorithms and nomogram. The models were then validated on a separate test set, and their differentiation and stability were assessed using evaluation indices like AUC and accuracy rate.Results:Underlying lung disease, smoking history, serum albumin≤35 g/L and radiotherapy history were identified as important influencing factors of CIP in all six models. The AUC of K nearest neighbor, support vetor machines (SVM), naive Bayesian, decision tree and random forest models predicted CIP were 0.647, 0.696, 0.930, 0.870, and 0.934, respectively. The AUC of the model created by the nomogram was 0.813, which was lower than the best random forest model in the machine learning algorithm, but with good predictive performance (AUC=0.934).Conclusions:The nomogram model can assess the patient′s risk more intuitively, but the risk prediction model of CIP based on a machine learning algorithm has a higher diagnostic value. It is suggested that the accuracy and usefulness of the prediction model can be increased by combining the nomogram's foundation with the machine learning algorithm.

Objective:To explore the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer and analyze the influencing factors, so as to provide theoretical basis for implementing precise interventions of occupational rehabilitation.Methods:This was a cross-sectional study. A convenient sampling method was used to select 257 postoperative patients with thyroid cancer in Zhujiang Hospital of Southern Medical University from May 2022 to July 2023. The General Information Questionnaire, Return-To-Work Self-Efficacy Questionnaire and Cancer Fatigue Scale were used for investigation. Latent profile analysis was used to explore the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer. Logistic regression and decision tree were used to analyze the influencing factors of different potential categories.Results:Finally, 250 postoperative patients with thyroid cancer were included. There were 76 males and 174 females, aged (37.91 ± 8.04) years old. The return-to-work self-efficacy of postoperative patients with thyroid cancer was divided into 2 potential categories: low return-to-work self-efficacy group (72.0%, 180/250) and high return-to-work self-efficacy group (28.0%, 70/250). Logistic regression showed education, thyrotropin suppressive therapy, cancer-related fatigue and age were factors influencing the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer ( OR values were 0.951 - 19.820, all P<0.05). Decision tree model showed education level and cancer-related fatigue were the most important factors ( χ2 = 31.40, 16.95, both P<0.05). Conclusions:There were two potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer. Most of them had low levels of return-to-work self-efficacy. Health care professionals should focus on patients who are less educated and having cancer-related fatigue, meanwhile, should not ignore patients who are substandard thyrotropin suppressive therapy, and older. Implement precise interventions of occupational rehabilitation to improve the return-to-work self-efficacy of postoperative patients with thyroid cancer so as to help them reintegrate into society.

A DNA fragment encoding recombinant human interleukin 11 (hrIL-11) was obtained by PCR from previously constructed pET24a-hrIL-11 plasmid. Then pET21a-hrIL-11 expression vector was constructed routinely and transformed into BL-21(DE3). By the induction of Isopropyl-1-thio-beta-D-galactoside (IPTG), hrIL-11 protein was highly expressed at about 20% of the total bacterial proteins and was identified by Western blot. After purification with Ni-NTA affinity chromatography and refolding with renaturation buffer, the purity of the target hrIL-11 protein reached 95% and its biology activity was 1 x 10(6) IU/mg, determined by stimulating the proliferation of T1165, which facilitates further researches into effects of IL-11 on platelet proliferation and other function.

Objective:To evaluate the effect of peer education on improving compliance of cardiac rehabilitation in patients with coronary heart disease.Methods:Totally 64 patients were randomly divided into two groups, namely, the experimental group and the control group with 32 cases in each group. Patients in the experimental group received routine education, nursing, and rehabilitation, plus the peer education treatment, whereas the control group only received routine treatment. The time lasts for 6 months. The compliance of cardiac rehabilitation and the score of China Questionnaire of Quality of Life in Patients with Cardiovascular Diseases (CQQC) were measured after 1 month, 3month and 6 month.Results:After 1, 3, and 6 months of intervention, the compliance of cardiac rehabilitation in the intervention group increased by 18.75%, 21.37%, and 21.88%, respectively, compared with the control group. After the first and third months of intervention, there was a statistically significant difference in the compliance rate of rehabilitation exercise between the intervention group and the control group ( χ2 values were 18.050, 16.946, respectively, P <0.05), and at the sixth month after intervention, the compliance of the two groups of patients with cardiac rehabilitation was not statistically significant ( χ2 value was 6.489, P> 0.05). After 1, 3, and 6 months of intervention, the quality of life scores of the intervention group were (88.68 ± 6.65), (81.90 ± 6.78), and (76.33 ± 5.90) points, and the quality of life scores of the control group were (84.75 ± 4.72), (75.67 ± 5.88), and (74.71 ± 9.47) points. There was significant difference in the scores of the two groups in the first and third months after the intervention ( t values were 2.235, 2.520, respectively, P<0.05); and in the sixth month after the intervention, the difference in the scores of the two groups wasn`t statistically significant ( t value was 1.049, P >0.05). Conclusion:Peer education can improve the compliance of cardiac rehabilitation and the score of CQQC in patients with coronary heart disease in 3 month, but further research is needed to confirm the long-term effect of peer education.

Objective:To evaluate the measurement agreement of Roche 25(OH)D immunoassay(evaluation method) with LC-MS/MS (reference method).Methods:A total of 909 residual serum samples from routine health check participants were collected from May to June in 2019. 25(OH)D concentrations were measured by evaluation method and LC-MS/MS, respectively. Passing-bablok regression, intraclass correlation coefficient (ICC), Bland Altman plots and Kappa test were used to analyze the consistency and bias on the results derived from the two measurement methods.Results:The 25(OH)D concentration derived from evaluation method was significantly different from those from LC-MS/MS method ( P<0.001). Slope of regression for evaluation method and LC-MS/MS was 0.962(95% CI 0.919-1.007), while intercept was -0.185 (95% CI -1.191-0.745). The ICC was 0.765 (95% CI 0.735-0.792). Altman plot showed that the average deviation between evaluation method and LC-MS/MS was -0.902 ng/ml (0.300%). The coincidence rate of evaluation method′s judgment of vitamin D sufficiency, insufficiency and deficiency with LC-MS/MS was 83.39%, and the weighted Kappa values was 0.790. Conclusion:Roche automatic 25(OH)D immunoassay shows acceptable correlation and agreement with LC-MS/MS, however, it is to note that the deviation between immunoassay and LC-MS/MS may lead to wrong judgment of vitamin D nutritional status. It is recommended that each laboratory should establish own corresponding reference values for 25(OH)D concentrations derived from these two methods.
