Objective To investigate the effects of 16-channel dedicated craniocerebral coil on brain magnetic resonance imaging(MRI)image quality in infants aged 0-6 months.Methods Thirty-two infants aged 0-6 months receiving craniocerebral MRI examination with 16-channel dedicated craniocerebral coil were enrolled as observation group,while 32 infant aged 0-6 months receiving craniocerebral MRI examination with conventional head and neck combined coil in the same period were enrolled as control group.The scanning sequences included transverse T1 weighted imaging(T1WI),T2 weighted imaging(T2WI),T2 fluid-attenuated inversion recovery(FLAIR)and diffusion-weighted imaging(DWI)sequences.The scanned images were evaluated subjectively and objectively.Results In the subjective evaluation,T1WI,T2WI and FLAIR sequences scored higher than 4,and DWI sequence scored higher than 3.There were high consistency between two raters for T1WI,T2WI and FLAIR sequences(Kappa value=0.717,0.652,and 0.784,respectively;P<0.05),and moderate consistency for DWI sequence(Kappa value=0.321;P<0.05).In the objective evaluation,the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of each sequence in the dedicated coil group were highly consistent in the left and right lobes of the brain,and the differences in the SNR and CNR between the left and right lobes of the brain were trivial(P>0.05).The SNR and CNR of each sequence in the dedicated coil group increased as compared with the conventional coil group,and the differences in the SNR and CNR of T1WI sequence and the SNR of DWI sequence were statistically significant(P<0.05).Conclusion The brain images of infants aged 0-6 months obtained with a dedicated craniocerebral coil can better meet the clinical needs,and the image quality of the dedicated coil group is superior to that of the conventional coil group in both subjective and objective evaluations.

Objective:To evaluate the safety of ensartinib in the treatment of anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) in the real-world clinical setting.Methods:Clinical data of 2 221 patients with ALK-positive locally advanced or metastatic NSCLC who received ensartinib treatment (225 mg/d) from December 16, 2020 to December 16, 2021 were collected and analyzed to assess drug adverse reactions in all population including elderly patients (≥ 65 years old) .Results:Among the total 2 221 patients, 511 patients (23.01%) experienced adverse events, including 8 patients (0.36%) who experienced serious adverse events. Adverse events led to dose modification in 67 patients (3.02%) and discontinuation in 18 patients (0.81%). The common adverse events were rash (407/2 221, 18.33%), pruritus (41/2 221, 1.85%), constipation (41/2 221, 1.85%), and facial edema (31/2 221, 1.40%). Thirty-six patients (1.62%) experienced ≥grade 3 adverse events. After symptomatic treatment of 511 patients with adverse reactions, 50 patients (9.78%) were healed, 271 patients (53.03%) were improved, 120 patients (23.48%) were persisted, and 70 patients (13.71%) were unknown due to loss of follow-up or other reasons. Forty-three patients (1.94%) reported 57 unintended adverse reactions. Among the 599 elderly patients, 116 patients (19.37%) experienced adverse events, including 1 patient (0.17%) who experienced serious adverse events. Adverse events led to dose modification in 25 patients (4.17%) and discontinuation in 5 patients (0.83%). The common adverse events of elderly patients were rash (88/599, 14.69%), constipation (14/599, 2.34%), facial edema (12/599, 2.00%), and pruritus (10/599, 1.67%). Twelve patients (2.00%) experienced ≥grade 3 adverse events. Among the 116 elderly patients with adverse reactions following the symptomatic treatment, 11 patients (9.48%) were healed, 58 patients (50.00%) were improved, 28 patients (24.13%) were persisted, and 19 patients (16.39%) were unknown due to loss of follow-up or other reasons. During the treatment, 1 patient (0.05%) experienced grade 2 interstitial lung disease, and no patient died due to adverse events.Conclusion:Ensartinib has a favorable safety profile in the real-world populations, with the most frequent adverse events being rash, mostly mild, and low incidence of ≥grade 3 adverse events. Overall, adverse reactions were tolerable and manageable.

Objective:To analyze the status of first viral load (VL) suppression for newly diagnosed HIV/AIDS on antiretroviral therapy (ART) from 2014 to 2016 in Shandong province, to provide theoretical evidence for improvement of ART effectiveness.Methods:Based on a retrospective cohort study, logistic regression model was used to identify influencing factors about VL suppression.Results:There were 4 833 newly diagnosed HIV/AIDS cases who received ART from 2014 to 2016 in Shandong province, and 3 449 cases achieved VL suppression at the first VL testing. The rate of first VL suppression was 71.36%. The possibilities of first VL suppression among patients on ART with education at junior high school, junior college and above were higher than those with education at primary school and below, with OR values at 1.75 and 2.00, separately. The possibilities of first VL suppression for patients treated at medical institutions was higher than those by CDC, with OR value 1.29. The possibilities of first VL suppression among patients whose CD4 count level at 201-350, 351-500 and ≥501 cells/μl were higher than that of the patients whose CD4 count level at ≤200 cells/μl, with OR values at 2.36, 2.11 and 2.66, respectively. The possibilities of first VL suppression among patients who missed doses was lower than those who did not miss doses, with OR value at 0.55. All the Pvalues for the above comparisons was <0.05. Conclusions:The suppression of viral load for HIV/AIDS on ART was influenced by culture level, CD4 count level at the entry of ART, treatment institutions and adherence to the therapy. Earlier diagnosis, treatment services provided by medical institutions and improvement of drug adherence can enhance ART effectiveness.

Objective To investigate the value of cytokines in bile combined with clinical indices in predicting the degree of liver injury after liver transplantation. MethodsA total of 16 patients undergoing liver transplantation who were hospitalized in Center of Organ Transplantation, The Affiliated Hospital of Qingdao University, from January to December 2018 were enrolled, and according to the level of alanine aminotransferase (ALT) on day 1 after surgery, the patients were divided into mild liver injury (ALT ＜500 U/L) group with 10 patients and severe liver injury (ALT ＞500 U/L) group with 6 patients. Bile samples were collected on days 1, 3, 5, and 7 after surgery, and MILLIPLEX assay was used to measure the levels of 17 cytokines. R software was used to perform principal component analysis (PCA) of bile cytokines and clinical indices and gene ontology (GO) enrichment analysis of bile cytokines. The two-independent-samples t-test was used for comparison of normally distributed continuous data between two groups; The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. A Spearman correlation analysis was performed to evaluate the correlation between clinical indices and bile cytokines. ROC curve analysis was used to evaluate the predictive value of cytokines in bile and clinical indices for liver injury after liver transplantation. ResultsCompared with the mild liver injury group, the severe liver injury group had significantly higher expression levels of bile Fractalkine (Z=-2.828, P=0.003), soluble CD40 ligand (sCD40L) (Z=-2.850, P=0.008), interleukin-4 (Z=-2.398, P=0.017), CXCL10 (Z=-2.475, P=0.023), and macrophage inflammatory protein-1α (Z=-1844, P=0.043). The correlation analysis showed that on day 1 after liver transplantation, aspartate aminotransferase, ALT, and lactate dehydrogenase were positively correlated with the levels of several cytokines in bile (all P＜0.05). The area under the ROC curve of Fractalkine, sCD40L and AST were 0.933 (0.812-1.000), 0.833 (0.589-1.000) and 0.917 (0.779-1.000), respectively, suggesting that AST and Fractalkine and sCD40L in bile on the first day after liver transplantation have significant predictive value for liver injury. The results of PCA showed that bile cytokines combined with clinical indices on day 1 after liver transplantation could better distinguish the patients with mild liver injury from those with severe liver injury. GO analysis showed that bile cytokines were associated with positive feedback regulation of external stimulus, cell chemotaxis, receptor ligand activity, cytokine activity, and cytokine-cytokine receptor interaction. ConclusionFractalkine and sCD40L in bile can predict the degree of liver injury after liver transplantation.

Objective: To analyze the epidemiological characteristics of HIV/AIDS infected students in Shandong Province, to provide a basis for the prevention and control of AIDS transmission in the student population. Methods: All 863 HIV/AIDS students cases during 2010-2019 were collected in Shandong Province. Epidemiological characteristics was described and the trends in the 10 years since 2010 was analyzed. Results: These 863 HIV/AIDS students were mainly transmitted through homosexual sex (763 cases, 88.41%), and the samples were mainly from voluntary consultation testing (433 cases, 50.17%). From 2010 to 2019, the proportion of student cases in the total number of cases showed an increasing trend ( χ 2 trend =30.21, P <0.01). Among them, the proportion of homosexual transmission cases increased year by year ( χ 2 trend =6.35, P =0.01), the proportion of cases aged 18-22 years increased year by year ( χ 2 trend =6.10, P =0.01), the proportion of cases with college degree or above increased year by year ( χ 2 trend =4.26, P =0.04). At present, voluntary consultation testing were the main source.There was no significant difference between the years of sample sources ( χ 2 trend =2.97, P =0.09). Conclusion The report number of students in Shandong Province are on the rise in recent years, especially those infected by same sex transmission, mainly with high education background, which calls for targeted strategies and intervention measures.

Objective:To analyze the timeliness and influencing factors of antiretroviral treatment (ART) among HIV/AIDS patients from 2017 to 2019 in Shandong province.Methods:Data were collected from the Chinese HIV/AIDS Comprehensive Response Information Management System, HIV/AIDS cases enrolled in antiretroviral therapy, from January 1, 2017 to December 31, 2019, ≥15 years of age and from the mainland of China were the subjects of the study. The general demographic characteristics (gender, age, ethnicity, education level, marital status, etc), infection routes, sample sources, date of diagnosis, baseline CD4+ T cell level, and clinical stage and other information were collected from the database. Univariate analysis was conducted for the timeliness of ART of the subjects by Chi square test, and the influencing factors associated with timeliness of ART were analyzed by binary non-conditional Logistic regression.Results:Among the 7 425 cases of HIV/AIDS, 6 813(91.8%) were male, 5 236(70.5%) had homosexual transmission, the age at the ART initiation was(36.05±12.51)years. The proportion of timeliness of ART within 30 d increased from 55.9% (1145/2050) in 2017 to 65.3% (1821/2789) in 2019. The possibility of timeliness of ART among HIV/AIDS who were married or cohabiting, education of high school and above were higher, with OR values at 1.136, 1.299. The possibility of timeliness of ART among HIV/AIDS cases whose domicile place is outside Shandong province were lower, with OR values at 0.664. The possibility of timeliness of ART in group of HIV/AIDS aging≥55, 45~54 and 35~44 years old were higher than that in 15~24 years old, with OR values at 1.530, 1.505 and 1.394. The possibility of timeliness of ART among the heterosexuals were lower than that of homosexuals, with OR values at 0.803. The possibility of timeliness of ART is lower for cases in places of detention centers than cases from volunteer testing and counseling, with OR values at 0.204. The possibility of timeliness of ART among HIV/AIDS cases whose CD4+ T lymphocyte at >500 cells/μL were lower than that of the cases whose CD4+ T lymphocyte at≤500 cells/μl, with OR values at 0.545. Patients without symptoms at baseline were less likely to receive prompt treatment than those with clinical symptoms, with OR values at 0.727. Patients with baseline clinical staging of stage Ⅳ, period of HIV/AIDS treatment with timeliness was longer than the cases with baseline clinical stages ofⅠ, Ⅱ, Ⅲ, with OR values at 1.307. Conclusions:The proportion of timeliness of ART increased from 2017 to 2019. Marital status, educational level, age, sample source, infection routes, baseline clinical stage, and CD4+ T lymphocyte levels were associated with the timeliness of ART.

Objective:To explore the clinical value of serum des-γ-carboxy prothrombin (DCP) in predicting hepatocellular carcinoma recurrence after liver transplantation.Methods:A total of 115 cases with hepatocellular carcinoma who underwent liver transplantation in Zhongshan Hospital Affiliated to Fudan University from October 2016 to December 2018 were retrospectively analyzed. Receiver operating characteristic curve analysis, Mann-Whitney U test, Kaplan-Meier method, Log-Rank test, χ2 test, univariate and multivariate Cox regression analysis and other statistical methods were used to explore the value of DCP in predicting tumor recurrence after liver transplantation and its correlation with clinicopathological characteristics.Results:The preoperative serum DCP level in recurrent population after liver transplantation was significantly higher than that in non-recurrent population ( P < 0.001). The optimal cut-off value of preoperative DCP for predicting recurrence was 200mAU/ml with the use of receiver operating characteristic curve. The sensitivity, specificity, Youden’s index and the receiver operating characteristic curve was 87.90%, 57.30%, 0.452, and 0.726, respectively. Survival analysis results grouped by this cut-off value showed that patients with preoperative DCP ≥200mAU/ml had a higher probability of recurrence ( P < 0.001). Further, subgroup survival analysis showed that patients with preoperative DCP≥200 mAU/ ml had a higher probability of recurrence than other cases of alpha-fetoprotein negative subgroup, cumulative tumor diameter ≤ 9 cm subgroup and Milan criteria subgroup ( P < 0.05). Cox regression analysis showed that preoperative DCP≥200 mAU/ ml ( P = 0.017) and cumulative tumor diameter > 9 cm ( P = 0.014) was an independent risk factor for recurrence after liver transplantation. χ2 test results showed that preoperative serum DCP level was correlated with gender, serum gamma glutamyltransferase level, serum alpha fetoprotein level, cumulative tumor diameter, vascular invasion, tumor differentiation and liver cancer transplant criteria ( P < 0.05). Conclusion:Preoperative serum DCP can be used as a supplement to the existing liver cancer transplant criteria to predict hepatocellular carcinoma recurrence after liver transplantation. In addition, the accurate screening of patients with low risk of HCC recurrence after liver transplantation can improve the prognosis and efficacy of liver transplant patients.
