[Purpose]To analyze the survival rate of prostate cancer patients hospitalized in Nan-tong Tumor Hospital from 2007 to 2017.[Methods]A total of 478 prostate cancer patients were admitted in Nantong Tumor Hospital from 2007 to 2017 and 476 cases(99.58％)were followed up till December 31,2020.The survival rate of patients was analyzed with Kaplan-Meier method;Soft-ware SPSS 25.0 and the Log-rank test were employed for statistical analysis.[Results]The aver-age age of prostate cancer patients at admission was(71.74±8.02)years old,and 79.08％were aged 60～79 years.The median survival time was 43 months,and the observed 1-,3-,5-and 10-year survival rates were 77.20％,56.07％,43.01％and 24.53％,respectively.The 5-year survival rates for the age groups of 35～59,60～79 and ≥80 years old were 31.73％,46.64％and 29.65％,respectively(P＜0.05).The 5-year survival rates for patients with stage Ⅰ～Ⅱ,stage Ⅲ,stage IV,and unknown stage were 88.10％,71.66％,33.35％and 37.55％,respectively(P＜0.001).The 5-year survival rates for the periods 2007-2012 and 2013-2017 were 32.85％and 47.79％,re-spectively(P＜0.05).Furthermore survival rates differed significantly across different regions within the jurisdiction(P＜0.05).[Conclusion]Over the past decade,the survival rate of hospital-based prostate cancer patients has significantly improved.Early-stage cases can achieve better survival rates,but the survival rate of elderly patients remains a challenge.Efforts should be made to reduce the proportion of patients with unknown staging Comprehensive measures for prostate cancer prevention and control should be strengthened to reduce incidence,improve prognosis and enhance quality of life of patients.

Objective To evaluate the accuracy of multiparametric imaging on the dual-source CT through acceptance and commissioning testing, and to provide a reference for standardized clinical application. Methods Both the adult and pediatric dual-source CT scanning modes were used to scan the electron density phantom, and identical multiparametric image reconstruction tasks were performed, including the conventional CT images, the mixed CT images, the virtual monoenergetic images, the iodine images, the electron density images, and the effective atomic number images. Results In the adult scanning mode, the virtual monoenergetic CT numbers showed the greatest difference for the cortical bone (1722 HU at 40 keV vs. 30 HU at 80 keV), with smaller differences observed for other materials as their atomic numbers decreased. The pediatric scanning mode exhibited a similar trend, with the largest difference occurring at 40 keV (1393 HU). In the adult scanning mode, the deviations between the theoretical and measured iodine concentration values were all within 5%, whereas in the pediatric scanning mode, the largest deviation was 15% for an iodine concentration of 2.0 mg/mL. For the electron density, the largest deviation between the theoretical and measured values occurred in the LN450 lung (9.18% in the adult scanning mode and 8.96% in the pediatric scanning mode); the deviations for the LN300 lung were all below 7.2%, for aluminum below 6.3%, and for other tissues within 3%. For the effective atomic number, the deviations between the theoretical and measured values were all within 5% in both scanning modes. Conclusion To ensure the accuracy and reproducibility of the dual-source CT applications, a comprehensive acceptance testing protocol should be established to guarantee the safety and precision of the CT localization process.

As the core force in medical services,healthcare professionals are key stakeholders in implementing the Healthy China strategy,strengthening public health awareness,and improving national health literacy.They must actively shoul-der the social responsibility of science communication.In the face of the rising mortality rate of coronary heart disease(CHD),they are obligated to scientifically disseminate relevant health knowledge to the public.This article takes the Fifth Internal Medi-cine Party Branch of the Second Clinical General Party Branch at Guangdong Provincial Hospital of Traditional Chinese Medicine(Dade Road Main Campus)as a typical case to explore how Party building can create the"Heart-Shaping"science popularization brand for CHD.The Party branch plays a leading and exemplary role by organizing resources and uniting Party members.Through cross-media integration,innovative content formats,and other methods,it fosters a strong atmosphere of science popularization under Party leadership,encouraging medical staff to break away from tradition and pioneer a diversified model of CHD science communication,successfully establishing the"Heart-Shaping"brand.Additionally,it meticulously cultivates a professional sci-ence communication team,achieving synergistic progress in both Party building and CHD science popularization.This provides replicable and practical innovative experience for Party building-driven CHD science communication,highlighting the unique ad-vantages of Party building in enhancing the effectiveness of CHD science popularization and promoting the integration of Party work and professional services.

Objective:To explore the inhibitory effect of protocatechuic acid (PCA) on the growth of ovarian cancer cell line A2780 and its mechanism.Methods:A2780 cells were cultured in vitro and randomly divided into a control group and protocatechuic acid-treated groups with concentrations of 5 μM and 10 μM. Cell proliferation was detected using the MTT assay; Cell migration ability was assessed through wound healing experiments; Cell cycle and apoptosis were analyzed using flow cytometry; Protein expression of apoptosis-related proteins was examined using Western blot.Results:Compared with the control group, the absorbance of the protocatechuic acid groups (5 μM, 10 μM) decreased after 48 hours, and protocatechuic acid significantly inhibited cell proliferation ( P<0.05) . In the 5 μM protocatechuic acid treatment group, the proportion of cells in the G2/M phase increased to 25.26%, and in the 10 μM treatment group, the proportion of cells in the G2/M phase increased to 24.99%. Protocatechuic acid groups could arrest the cell cycle of the human ovarian cancer cell line A2780 at the G2/M phase. Protocatechuic acid groups could also promote the increase of early and late apoptosis rates of A2780 cells, leading to the upregulation of the expression levels of related apoptotic proteins CASPASE-3 and Bax, while the expression level of the anti-apoptotic protein Bcl2 was downregulated. Conclusions:Protocatechuic acid can inhibit proliferation and migration of A2780 ovarian cancer cells, arrest the cell cycle of A2780 cells, and promote apoptosis. The mechanism of action may be related to the upregulation of apoptosis-related proteins BAX and caspase3.

Objective To analyze the survival status of inpatients with cervical cancer registered in Nantong admitted in Nantong Cancer Hospital from 2002 to 2017. Methods Inpatients with cervical cancer in Nantong Cancer Hospital were followed up from 2017 until December 31, 2020 using active and passive methods to determine their survival outcome. The rate of follow-up loss was statistically analyzed by Chi-square test, the observed survival rate for each year was calculated using the life table, the survival curve was drawn with R language, and the survival rates of patients in different age groups and from different regions were compared with log-rank test (Mantel-Cox). Results A total of 5645 cervical cancer cases were registered. Among them, the survival outcome was recorded for 5512 cases. The success rate of follow-up was 97.64%, and the loss of follow-up rate was 2.36%. The average age of onset was 56.67±12.78 years. The median survival time was 6.54 years, and the 1-, 3-, 5-, and 10-year observed survival rates were 91.50%, 76.95%, 60.99%, and 28.51%, respectively. Among the age groups, significant differences in survival rate were observed between the 15- and 60-year-old groups (χ²=7.469, P=0.006) and between the 15- and 80-year-old groups (χ²=36.317, P < 0.001). No significant difference in survival rate was found between patients from Haimen and Qidong (χ²=2.779, P=0.095) and between patients from Qidong and Tongzhou (χ²=0.515, P=0.473). Significant difference in survival rate was observed among other regions (P < 0.05). Conclusion In this study group, the survival rates of hospital-based patients with cervical cancer significantly differ among the age groups and regions of origin and significantly decreased with age. The high follow-up rate fully reflects the comprehensive effect of the treatment in Nantong Cancer Hospital for registered patients with cervical cancer in Nantong.
