Objective To explore the impact factors of volume reduction rate(VRR)of benign thyroid nodules after thermal ablation based on conventional ultrasound and contrast-enhanced ultrasound(CEUS)manifestations.Methods Totally 238 patients with benign thyroid nodules who underwent thermal ablation were retrospectively enrolled and divided into VRR＜75%group(n=93)and VRR≥75%group(n=145)according to VRR of lesions 12 months after treatment.Multivariate logistic regression analysis was used to screen the independent impact factors of VRR of lesions 12 months after thermal ablation based on conventional ultrasound and CEUS manifestations.Receiver operating characteristic curve was plotted,the area under the curve(AUC)was calculated to evaluate the efficacy of the combination of the above factors for predicting VRR of lesions.Results High echo,calcification,cystic and solid components,high enhancement,enhancement loss and high ablation energy were all independent risk factors,while circular enhancement was the independent protective factor of VRR of benign thyroid nodules 12 months after thermal ablation(all P＜0.05).The AUC of combination of the above factors for predicting VRR of benign thyroid nodules 12 months after thermal ablation was 0.926.Conclusion High echo,calcification,cystic and solid components,high enhancement,enhancement loss and high ablation energy were all independent risk factors,while circular enhancement was the independent protective factor of VRR of benign thyroid nodules 12 months after thermal ablation.

Objective To explore the effect of different post-processing methods of total spinal CT angiography(CTA)for displaying spinal dural arteriovenous fistula(SDAVF).Methods Total spinal CTA data of 55 patients with SDAVF were retrospectively analyzed.Traditional post-processing of original CTA images(modified tissue growth boneless volume rendering[VR]and full-range axial maximum intensity projection[MIP])were performed,while the axial,sagittal and coronal MIP reconstructions,axial,sagittal and coronal VR reconstructions,as well as axial,sagittal and coronal MIP+VR reconstructions of original CTA images on lesion layers were completed,respectively.Taken digital subtraction angiography(DSA)as the gold standards,a 5-point scale was used to subjectively evaluate the effect of displaying the location,the range and feeding artery of fistula shown on CTA images based on different post-processing methods.Results No significant difference of subjective score of location nor feeding artery of fistula was found among axial MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images reconstructed using other post-processing methods(all P＜0.05).Meanwhile,no significant difference of subjective scores of the range of SDAVF was detected among sagittal MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images obtained using other post-processing methods(all P＜0.05).Conclusion The location and feeding artery of SDAVF could be observed based on axial MIP,VR and MIP+VR reconstructions of the total spinal CTA,while sagittal MIP,VR and MIP+VR reconstructions were conducive to display the range of SDAVF.Combination of multiple post-processing methods was helpful for comprehensive understanding the composition and range of SDAVF.

Objective:To assess the real-world patient satisfaction with the outcomes in Chinese patients who received HYC-24/HYC-24+ for the treatment of moderate to severe nasolabial folds (NLF).Methods:This study was a prospective, observational, multicenter, real-world cohort study in which patients accepted treatment with HYC-24/HYC-24+ in China during a period from August 2018 to August 2020 at Beijing Lidu Medical Beauty Hospital, Hangzhou Yanshu Yuerong Medical Aesthetic Clinic, and Guangzhou Yuexiu Plastic Surgery Hospital and were followed up for up to 1 year. Patients were adults aged 18 to 65 years with moderate to severe NLF who had not received cosmetic treatment for NLF within 6 months prior to study enrollment. Post-treatment study visits were conducted at Months 1, 6, 9, and 12, but only Months 6 and 9 were required visits. The primary patient-reported outcomes endpoints included the FACE-Q satisfaction with outcome total score (a score from 0 to 100: a higher score indicates better outcomes and higher patient satisfaction), FACE-Q appraisal of lines - NLFs total questionnaire score mean change from baseline (a score from 0 to 100: a higher score indicates the patient was less troubled by NLF in the past week), and proportion of patients who reported that they looked younger than the actual age on the FACE-Q patient perceived age visual analog scale (VAS). Investigator-assessed endpoints included the proportion of patients with a global aesthetic improvement scale (GAIS) score of ≥ 1 point and the proportion of patients with an improvement in NLF severity of ≥ 1 point using the nasolabial fold severity scale (NLFSS). Statistical analyses were performed with SAS software, version 9.4. Measurement data were expressed as Mean±SD, and count data were expressed using cases(%). For both measurement and count data, P values were calculated on the difference between score values at different time points versus baseline using the Wilcoxon signed rank test. Results:A total of 52 subjects were enrolled and treated. Among these subjects, 7 were not included in the 6-month effectiveness analysis data set because the visit time exceeded the visit assessment window, and only 9 patients completed the 12-month visit. All patients were Chinese women, aged 26 to 62 years old, with a mean age of 40.7 years. The FACE-Q satisfaction with outcome total score was (68.76 ± 21.03) points (38-100) at Month 6, and (65.44±18.24) points (24-100) at Month 9, indicating high patient satisfaction with the treatment. The FACE-Q appraisal of lines-NLFs total score was (42.4±15.1) points (10-69) at baseline, (76.9±20.6) points (36-100) at Month 6, and (74.2±16.7) points (36-100) at Month 9, both significantly higher than the baseline scores (both P<0.01). The mean change from baseline in the FACE-Q appraisal of lines-NLFs total scores at Month 6 and Month 9 were 34.9 and 31.8 points, respectively, indicating the disturbance caused by NLF was relatively mild after treatment. The proportion of patients who believed they looked younger than their actual age on the FACE-Q patient perceived age VAS increased from 28.9% (15/52) at baseline to 77.8% (35/45) at Month 6, and 73.1% (38/52 ) at Month 9. The differences were all statistically significant compared to baseline ( P <0.01). At each post-baseline visit, all patients had ≥ 1-point improvement on the GAIS scale, indicating an improvement in patient NLF appearance in the investigators’ opinion. In terms of the NLFSS assessment, 97.8% (44/45) and 82.7% (43/52) of patients achieved a ≥ 1-point improvement on the NLFSS at Months 6 and 9, respectively. No adverse events were reported during the study. Conclusion:In a real-world setting, after the administration of HYC-24/HYC-24+ to Chinese patients, the patients were satisfied with the outcomes based on validated questionnaires. The patients also reported looking younger than their actual age and being less disturbed by NLF. Clinician-reported outcomes were consistent with patient-reported outcomes, indicating improvement in NLF.

ObjectiveTo determine the influence of COVID-19 prevention and control on the epidemic characteristics and dynamics of notifiable infectious diseases in the first quarters， Zhejiang Province， and to explore more effective countermeasures against infectious diseases. MethodsDescriptive epidemiology was conducted to determine the change in notifiable infectious diseases during the prevention and control of COVID-19 in Zhejiang Province by retrieving the data of notifiable infectious diseases from 2017 to 2022 in the Chinese information system for disease control and prevention. Cumulative reported new cases of notifiable infectious diseases in the first quarters of 2017‒2019 were compared with that of 2020‒2022. ResultsA total of 546 753 cases of notifiable infectious diseases were newly reported in the first quarters of 2017‒2019， with an average incidence of 321.92/10⁵. In contrast， a total of 509 908 cases of notifiable infectious diseases were newly reported in the first quarters of 2020‒2022， during which the COVID-19 epidemic occurred， with an average incidence of 270.39/10⁵. The incidence in 2020‒2022 significantly declined by 51.53/10⁵， compared with that in 2017‒2019 （χ²=8 072.06， P<0.001）. In the first quarters of 2020‒2022， the average incidence of zoonotic diseases and vector-borne diseases decreased by more than 50%. In addition， the incidence of respiratory， enteric， blood-borne， and sexually transmitted diseases declined to certain degree. ConclusionThe decline in the newly reported cases of non-COVID-19 notifiable infectious diseases in the first quarters of 2020‒2022 indicates that the countermeasures against COVID-19 epidemic， such as multi-disease co-prevention， multi-sectoral collaboration， societal mobilization and personal hygiene and protection， may also decrease the incidence of multiple infectious diseases. It suggests the countermeasures are effective， which would provide evidence for routine prevention and control of infectious diseases in future.

Hepatocellular carcinoma (HCC) is a kind of primary liver cancer with a high mortality rate. In China, the incidence ratio in males to females with HCC is 2:1–5:1. The difference in sex hormone pathways between males and females and the interaction between androgen/androgen receptors and HBV can lead to an incidence difference between males and females with HCC. Hence, the androgen/androgen receptor oncogenic pathway in hepatocellular carcinoma has received considerable attention. This review mainly summarizes the recent research progress on the androgen/androgen receptor oncogenic pathway in hepatocellular carcinoma.

Malignant tumors can be classified into three categories， rapidly progressing tumors， slowly progressing tumors， and "indolent" tumors. Rapidly progressing tumors （such as liver cancer， pancreatic cancer， and cholangiocarcinoma） have acute onset， shorter time duration from onset to death， and poorer treatment effects， which warrants primary prevention. Slowly progressing tumors （such as lung cancer， colorectal cancer， breast cancer， and gastric cancer） have slow onset， clear precancerous lesions， longer time duration from onset to death， and better therapeutic effects， which is accordingly suitable for secondary prevention. “Indolent” tumors （such as prostate and thyroid cancer） do not affect the life expectancy and are suitable for tertiary prevention. Early screening of “indolent” tumors may lead to overtreatment. Furthermore， early screening of rapidly progressing tumors is difficult to identify early cancers， which results in low cost-effectiveness. In contrast， for slowly progressing tumors suitable for secondary prevention， early screening may have cost-effectiveness， though there might be over-diagnosis. It is crucial to adopt appropriate prevention and treatment strategies for diverse types of tumors. Currently， large-scale cohort studies and randomized controlled clinical trials with complete follow-up may accurately evaluate the effect of cancer prevention strategies. This review discusses the significance of screening in precision prevention of tumors based on the characteristics of tumor progression and patients’ prognosis.

ObjectiveTo investigate the related factors of hypertension and comorbid hypertension-diabetes mellitus （HT-DM） among rural residents in Shanghai， China. MethodsA total of 2 159 residents over 35 years old were randomly selected from a rural community in the suburbs of Shanghai through cluster random sampling. Their basic sociological characteristics and blood lipid levels were investigated. Chi-square test was used to analyze the relationship between hypertension （or HT-DM） and gender， age， education levels， marital status， original household registration and current household registration. The relationship between hypertension （or HT-DM） and blood lipid level was analyzed by a conditional logistic regression model. ResultsThe prevalence of hypertension was 26.35% and that of HT-DM was 4.68% in the study population. Chi-square test analysis showed that hypertension was significantly associated with age， marital status， educational level， and rural household registration， while HT-DM was significantly associated with age， educational level， and rural household registration. Chi-square trend analysis indicated that the prevalence of hypertension and HT-DM increased with age in both male and female populations （χ²=129.82， 193.04，both P<0.001， and χ²=9.29， 40.57， both P<0.01）. The unconditional logistic regression analysis indicated that the lower level of high-density lipoprotein cholesterol （HDL-C） and higher level of triglyceride （TG） were associated with an increased the risk of hypertension by 2.79 times and 2.06 times， respectively. The lower level of HDL-C increased risk of HT-DM by 4.21 times. ConclusionThe prevalence of hypertension in the rural population in Shanghai is relatively high. Age， education level， rural household registration and HDL-C are common related factors of hypertension and HT-DM.
