Objective:To investigate the accuracy of risk perception for atherosclerotic cardiovascular disease (ASCVD) among community residents in Jining and analyze its influencing factors.Methods:Using a multistage cluster random sampling method, community residents from eight communities in Jining were selected between September 2022 and December 2023. Data were collected using a general demographic questionnaire, objective ASCVD risk assessment, the Chinese version of the Attitudes and Beliefs about Cardiovascular Disease Risk Questionnaire-Chinese Version (ABCD-C), the 2018 National Health Literacy Monitoring Survey, and a Self-reported Health Status Questionnaire.Results:Among 955 residents, 325 accurately estimated their ASCVD risk, 173 underestimated it, and 457 overestimated it. Education level and health literacy were influencing factors for overestimating ASCVD risk ( P<0.05), while education level, health literacy, family history of ASCVD, and self-reported health status were influencing factors for underestimating ASCVD risk ( P<0.05) . Conclusions:A significant proportion of Jining community residents underestimated their ASCVD risk. Nurses conducting ASCVD primary prevention education should provide tailored health education based on the local characteristics and cultural background of Jining. Special attention should be given to residents with lower education levels and health literacy, as well as those without a family history of ASCVD or with self-perceived good health, to prevent underestimation of their ASCVD risk.

Objective:To evaluate the feasibility of low radiation dose and low contrast dosage in coronary CT angiography (CCTA) of class I obese patients.Methods:This prospective study enrolled 57 patients (male/female, 50/7, age, 25-77 years) with body mass index (BMI) of 30-38 kg/m 2 and body weight of 85-119 kg scheduled for CCTA from August 2022 to March 2023 in our hospital. The patients were divided into two groups: control group (group A, n = 20) and low-dose group (group B, n = 37). Group A employed a standard-dose protocol: tube voltage 120 kVp and IDR 2.2 g I/s, while group B were scanned using the low-dose protocol: tube voltage 100 kVp and IDR 1.5 g I/s. Images in Group A and Group B were reconstructed with hybrid iterative reconstruction (HIR) at strength 4 and 8, respectively. Other scanning and reconstruction parameters were the same in two groups. Methods:The image quality was assessed by measuring the CT values and noise in the aortic root, left anterior descending artery and right coronary artery, and the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. Subjective image quality was evaluated for vessels according to the 18-segment classification system using a 4-point scale (1. poor, 4. excellent). The effective dose E and contrast dosage were compared. Statistical analysis was performed using independent samples t-test, Mann-Whitney U test or χ 2 test. Results:The BMI of groups A and B were 31.89 (30.77, 33.81) and 31.22 (30.46, 32.83) kg/m 2, respectively ( P>0.05). No statistically significant differences in CT values, noise, SNR, CNR were noticed between the two groups (all P>0.05). The mean subjective score of all coronary artery segments in the two groups were not less than 3, meeting the requirement of clinical diagnosis. There was no statistically significant difference in the overall subjective image quality between the two groups ( P>0.05). The radiation dose E in groups A and B were 7.58 and 4.49 mSv, respectively ( Z=-5.46, P<0.05). The contrast dosage in groups A and B were 66 and 45 ml, respectively. The radiation dose E and contrast dosage in group B were 41% and 32% lower than that in group A, respectively. Conclusions:For class I obese patients, it was feasible to use a low tube voltage (100 kVp) and low IDR (1.5 gI/s) protocol in CCTA. Radiation dose and contrast dosage can be reduced reasonably without compromising the CCTA image quality.

AIM:To evaluate the effectiveness of heparin-binding protein(HBP)in combination with organ function indicators for early diagnosis and prognosis prediction in patients with severe trauma complicated with sepsis.METHODS:A retrospective analysis was conducted on 184 patients with multiple injuries who were admitted to the Emergency Medicine Department of the Second Affiliated Hospital of Zhejiang University Medical College between January 2019 and September 2020 and underwent HBP testing.Patients were classified according to the SEPSIS 3.0 diagnostic cri-teria into a sepsis group(n=89)and a non-sepsis group(n=95).Clinical outcomes were tracked,dividing patients into a deceased group(n=43)and a survival group(n=141).HBP levels were continuously measured,and the peak values of the two groups were compared to assess the efficacy of diagnosing sepsis.Further analysis on the correlation of HBP peak value median with clinical prognosis was conducted.The effectiveness of HBP alone and in combination with total biliru-bin(TBil)and white blood cell(WBC)count in prognosis assessment was evaluated.RESULTS:(1)No significant dif-ference was found in the peak level of HBP between the sepsis group(n=89)and the non-sepsis group(n=95)(71.7±68.6 vs 52.5±56.1,P=0.051).(2)Among the 184 patients,the peak level of HBP was positively correlated with WBC count(r=0.244,P<0.01)and TBil levels(r=0.241,P<0.01).(3)The area under curve(AUC)for independent diag-nosis of sepsis using TBil levels,WBC count,and PCT levels were 0.618,0.631,and 0.718,respectively,and the com-bined AUC was 0.684,with a diagnostic sensitivity of 60.7%and specificity of 71.6%(P<0.05).(4)Prognostic analy-sis of mortality showed that patients in the high HBP level group had a significantly higher mortality rate than those in the low-level group(30.4%vs 16.3%,P<0.05).The WBC count was also significantly higher in the deceased group than in the survival group(17.5±6.9 vs 12.8±4.7,P<0.01),especially in those with sepsis(P<0.01).The AUCs for predict-ing sepsis mortality prognosis using HBP peak level,TBil levels,WBC count,SOFA score,and APACHE-II score were 0.618,0.603,0.719,0.823,and 0.811,respectively.The combined AUC of HBP with TBil and WBC for assessing sepsis prognosis was 0.750,with a sensitivity of 74.4%and specificity of 74.5%,showing statistically significant differ-ences(P<0.05).(5)The combined assessment of these three indicators showed no statistically significant difference from artificial scoring systems in predicting sepsis prognosis(P>0.05).CONCLUSION:The combination of HBP,TBil,and WBC is highly effective in predicting the risk of sepsis in patients with multiple injuries and has significant clinical value in predicting the mortality risk of trauma patients with sepsis.

Chimeric antigen receptor T cell (CAR-T) therapy, an emerging immunotherapy, has achieved remarkable results in the treatment of hematologic tumors. However, it's limited in the treatment of solid tumors such as esophageal squamous cell carcinoma due to various factors. Clarifying the reasons for the limitation of CAR-T therapy and exploring the corresponding solutions can provide new ideas and insights for the treatment of esophageal squamous cell carcinoma.

Proteins and peptides have become a significant therapeutic modality for various diseases because of their high potency and specificity. However, the inherent properties of these drugs, such as large molecular weight, poor stability, and conformational flexibility, make them difficult to be formulated and delivered. Injection is the primary route for clinical administration of protein and peptide drugs, which usually leads to poor patient's compliance. As a portable, minimally invasive device, microneedles (MNs) can overcome the skin barrier and generate reversible microchannels for effective macromolecule permeation. In this review, we highlighted the recent advances in MNs-mediated transdermal delivery of protein and peptide drugs. Emphasis was given to the latest development in representative MNs design and fabrication. We also summarize the current application status of MNs-mediated transdermal protein and peptide delivery, especially in the field of infectious disease, diabetes, cancer, and other disease therapy. Finally, the current status of clinical translation and a perspective on future development are also provided.

Objective To compare the efficacy and safety of the long-term intermittent maintenance treatment with tacrolimus 0.03％ ointment versus traditional treatment in reducing relapses and prolonging the recurrence interval in children with moderate to severe atopic dermatitis (AD).Methods A two-phase randomized,open-labelled,controlled clinical trial was conducted from September 2012 to November 2013.In the first phase,a total of 171 children aged 2-15 years with moderate to severe AD were enrolled from 7 hospitals in China,and received conventional treatment with tacrolimus 0.03％ ointment twice a day for 2-6 weeks.At the end of the treatment,the patients who achieved an investigator's global assessment (IGA) score ≤ 2 (n =125) were randomly classified into 2 groups to receive the second-phase treatment:test group (n =62) receiving intermittent maintenance treatment with tacrolimus 0.03％ ointment twice a week (Monday and Thursday),and control group (n =63) receiving no treatment.If the patients in the 2 groups experienced relapse,they received conventional treatment with tacrolimus 0.03％ ointment twice a day.The overall observation period was 6 months.The primary endpoint was the time to the first relapse,which was defined as the number of days from the end of the first-phase treatment to the first relapse.The secondary endpoints included the number of relapses at the second-phase trial,the disease severity at the time of relapse,the duration of relapse,the pruritus score at the time of relapse,the total amount of tacrolimus ointment used,the total response rate at the second-phase trial,and the incidence of adverse events.Results A total of 125 children with AD were enrolled into the second-phase trial,and 121 of them completed the follow-up.Among the 121 patients,the recurrence rate was significantly lower in the test group (25/60,41.7％) than in the control group (46/61,75.4％;x2 =14.20,P ＜ 0.001).The time to the first relapse was significantly longer in the test group (46.9 ± 37.7 d) than in the control group (28.8 ± 32.3 d;Z =1 093.50,P =0.020).The total number of recurrence was 31 and 86 in the test group and control group respectively,and the mean number of recurrence in each patient was significantly lower in the test group (0.52 ± 0.68) than in the control group (1.41 ± 1.23,t =4.96,P ＜ 0.001).There were no significant differences between the two groups regarding disease severity during relapse (eczema area and severity index:Z =971.50,P =0.39),duration of relapse (Z =747.00,P =0.07),and pruritus score during relapse (Z =894.00,P =0.95).The therapeutic drug was tolerated well in all the children,and no tacrolimus-related serious adverse events occurred.Conclusion The intermittent maintenance treatment with tacrolimus 0.03％ ointment twice a week for 6 months can effectively and safely prevent and reduce relapses,and prolong the recurrence interval in children with moderate to severe AD.

Objective To explore the value of diffusion kurtosis imaging (DKI) histogram analysis for differential diagnosis of prostate cancer and noncancerous foci and the correlation between histogram parameters and Gleason score. Methods Twenty?one patients were retrospectively enrolled in Beijing Hospital from May 2017 to May 2018. All subjects underwent Philips 3.0 T MR scanning. The pathologies were confirmed by in?bore MR?guided biopsy. Finally, 31 lesions were collected (two lesions each from 10 patients), including 15 prostate cancer and 16 noncancerous foci (benign prostatic hyperplasia and prostatitis). ROI was drawn manually by two experienced radiologists. All the lesions were measured mean apparent diffusion coefficient (Dapp), mean apparent kurtosis coefficient (Kapp) and their histogram parameters, the averages of two measurements were used to be calculated. The values of these parameters in cancer and noncancerous foci were compared using independent?samples t test. The Spearman test was used to evaluate the correlation of these parameters and Gleason scores of prostate cancer. Results Mean Dapp, 10th Dapp, 25th Dapp, 50th Dapp, 75th Dapp, 90th Dapp, minimum Dapp, maximum Dapp, mean Kapp, 50th Kapp, 75th Kapp, 90th Kapp, maximum Kapp between prostate cancer and noncancerous foci were statistically significant (P<0.05). 90th Kapp (r=0.630, P<0.05) and maximum Kapp (r=0.565, P<0.05) increased with the Gleason scores increasing. Conclusion Histogram analysis of DKI model is valuable for diagnosing and assessing aggressiveness of prostate cancer.
