Objective:To explore the feasibility of using Double FLASH coronary CTA (CCTA) to evaluate myocardial blood perfusion based on the original Patlak Plots.Methods:A total of 50 subjects with non-ischemic heart disease were prospectively included in the study who received dynamic myocardial CT perfusion (CTP) and Double FLASH CTA scans in General Hospital of Tianjin Medical University from January 2018 to January 2020 due to coronary heart disease or suspected coronary heart disease. The age of the enrolled patients was at least 18 years old and there was no moderate or above stenosis on CTA. The dynamic CTP images were analyzed by using CTP analysis software on FRONTIER platform to calculate the CTP derived MBF (MBF CTP). While the CTA derived MBF (MBF CTA) was calculated from the CT attenuation values of both aorta and myocardium segments on two scanning time set of Double FLASH CTA which were measured by two independent radiologists. Pearson correlation and Bland-Altman analysis were used to compare the results of MBF CTP and MBF CTA. Results:There was a strong linear correlation between MBF CTP and MBF CTA measurements. In the mid anteroseptal level: MBF CTA=0.936MBF CTP-11.999, r2=0.600, P<0.01. In the mid anterolateral level: MBF CTA=1.010MBF CTP-9.206, r2=0.448, P<0.01. In the apex: MBF CTA=0.822MBF CTP+16.904, r2=0.375, P<0.01. Bland-Altman analysis also showed there were no significant differences between MBF CTP and MBF CTA measurements. Compared with dynamic CTP scan, Double FLASH CTA mode significantly reduced the radiation dose [(4.33±1.89) mSv vs. (1.38±0.19) mSv, t=4.378, P=0.030]. Conclusions:This study validated the feasibility and accuracy of the MBF CTA measurement based on the theory of Patlak Plots only using Double FLASH CTA images. This method might have the potential to expand the clinical application of one-stop CTP examination for simultaneously evaluating coronary artery and myocardial ischemia in the clinic.

Objective:To deliver understanding of the latest research progress on clinical trials and approval of dermatological drugs in China in 2020.Methods:A registration and information disclosure platform for drug clinical studies and a query system for domestic and imported drugs in the National Medical Products Administration of China were searched for registered clinical trials and approved dermatological drugs, respectively. The number and stages of clinical trials, indications and classification of involved products, and listed dermatological drugs in 2020 were summarized and depicted.Results:There were 157 dermatological drug trials registered in China in 2020, accounting for 6.16% of all the 2 548 clinical drug trials, including 127 (80.9%) initiated by Chinese pharmaceutical enterprises and 25 (15.9%) international multicenter trials. Among the 127 drug trials initiated by Chinese pharmaceutical enterprises, bioequivalence trials were mostly common, accounting for 55.9% (71/127) . Compared with global pharmaceutical enterprises, domestic pharmaceutical companies initiated significantly decreased proportions of international multicenter trials (1.9% [3/157] vs. 14.0% [22/157], P < 0.001) , but significantly increased proportions of phaseⅠclinical trials and bioequivalence trials (24.4% [31/127] vs. 10.0% [3/30], 55.9% [71/127] vs. 0, respectively, both P < 0.001) . Totally, 90 kinds of dermatological drug were involved in all the trials, psoriasis, atopic dermatitis and melanoma were the most common indications, and innovative drugs accounted for 53.3% (48/90) ; the proportion of innovative drugs was significantly lower in domestic pharmaceutical companies than in global pharmaceutical companies (43.2% [32/74] vs. 16/16, P < 0.001) . In addition, 28 dermatological drugs developed by 22 pharmaceutical companies were approved in China in 2020, of which 21 drugs were developed by domestic pharmaceutical companies. Conclusion:Clinical drug trials carried out by domestic pharmaceutical companies mostly focus on generic drugs, and it is still necessary for domestic pharmaceutical companies to further improve the innovation ability.

Objective To understand the incidence and mortality of colorectal cancer in China. Methods The data from GLOBOCAN 2012,Chinese Cancer Registry Annual Report 2012, Cancer Incidence in Five Continents(CI5),the Three National Death Cause Surveys in China and WHO Mortality Database were used to learn about the incidence and mortality of colorectal cancer and related trends in China. Results It was estimated by GLOBOCAN 2012 that in 2012 the age-standardized incidence of colorectal cancer in China was 16.9 per 100 000 in males and 11.6 per 100 000 in females,and the age-standardized mortality was 9.0 per 100 000 in males and 6.1 per 100 000 in females. GLOBOCAN 2012 estimated that colorectal cancer incidence and mortality would increase with the level of human development index. China’s human development level was high, suggesting that the burden of colorectal cancer would be more serious in China with the development of social economy. The data from CI5 VolumeⅣand GLOBOCAN 2012 indicated that the incidence of colorectal cancer began to increase obviously at age of 50 years in China. Chinese Cancer Registry Annual Report 2012 showed that the incidence and mortality of colorectal cancer in urban population were two times higher than those in rural population in 2009,the proportions of colon cancer among colorectal and anus cancers,which was 49.0% in males and 54.2% in females,53.4% in urban population and 41.7%in rural population. CI5 VolumesⅣ-Ⅹshowed that colon cancer and rectum and anus cancer incidence in Shanghai for both males and females were increasing during the period 1973-2007. The percentage change in colon cancer and rectum and anus cancer incidence between 1973-1977 and 2003-2007 increased by 138.8%and 31.1%in males,146.7%and 49.1%in females, respectively. The data from the Three National Death Cause Surveys showed that the crude mortality of colorectal cancer increased by 77.9%form mid 1970’s(1973-1975)to mid 2000’s(2004-2005). WHO Mortality Database showed that average annual percentage change(AAPC)of age-standardized colorectal cancer mortality increased by 0.7%(P<0.05) from 1987 to 2000. Conclusion More attention should be paid to the prevention and control of colorectal cancer in urban area and in male population in China. Similar to the western countries,the burden of colorectal cancer in China would continue to become serious if no population based prevention and control programs are conducted.

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (≥ 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and ≥60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.
