It is believed that retention due to deficient qi is an important pathogenesis of endometriosis （EMs）. Deficient qi is the root of the disease， mainly manifested as spleen deficiency， while retention is the branch pathogenesis of the disease， mainly with blood stasis， complicated with constraint， phlegm， heat， toxin and other pathological factors. Therefore， it is proposed to follow the treatment principle of supplementing deficiency and unblocking stagnation， and take the methods of replenishing qi and fortifying the spleen， removing stasis and eliminating concretions. Self-made Fuzheng Huayu Formula （扶正化瘀方） is taken as the basic formula， and can be modified with the symptoms in menstrual and non-menstrual periods. Additionally， the methods of moving qi， dispelling phlegm， clearing heat， relieving toxin and others can be combined， and it is recommended to treat the root and the branch simultaneously.

Objective To establish a quality indicator system of interventional nursing.Methods Taking Donabedian quality structure model as the theoretical basis and through literature analysis,expert meeting and summarizing the clinical problems,the first draft about interventional nursing care quality indicators was composed,which included 3 first-level indicators,12 second-level indicators and 55 third-level indicators.A total of 27 experts on interventional nursing and nursing administration were selected from 25 grade-3A level hospitals in 13 provinces and cities of China.The Delphi method was used to conduct two rounds of expert correspondence consultation,and the quality indicator system of interventional nursing was established.Results Finally,a quality indicator system of interventional nursing,which included 3 first-level indicators,7 second-level indicators and 29 third-level indicators,was formulated.In both the two rounds of expert letter inquiry,the positive coefficient and authority coefficient were 100％and 0.95 respectively.The coefficient of variation of each index in the first and the second round of expert letter inquiry was 0-0.25 and 0-0.21 respectively.In the first round of expert letter inquiry,the Kendall harmony coefficients of the first-level,second-level and third-level indexes were 0.672,0.271 and 0.341 respectively,while in the second round of expert letter inquiry,the Kendall harmony coefficients of the first-level,second-level and third-level indexes were 0.462,0.475 and 0.330 respectively,the differences were statistically significant(all P＜0.01).Conclusion The quality indicator system of interventional nursing established in this study carries a relatively high reliability and scientific nature,and it can provide reference for evaluating and monitoring the safety and quality control in interventional nursing.

Objective To explore the effect of virtual reality(VR)technology on relieving intraoperative pain in patients receiving transcatheter hepatic artery chemoembolization(TACE).Methods A total of 76 patients,who received TACE from June 2023 to January 2024,were enrolled in this study.Using random number table method,the patients were divided into control group(n=38)and study group(n=38).Intraoperative routine nursing was carried out for the patients of the control group,while on the basis of routine nursing additional VR technology was adopted to relieve the intraoperative pain for the patients of the study group.The degree of intraoperative pain,anxiety symptoms,incidence of intraoperative adverse reactions and patient satisfaction with nursing were compared between the two groups.Results The degree of intraoperative pain in the study group was lower than that in the control group,but the difference between the two groups was not statistically significant(P＞0.05).The analgesic effect of VR was much obvious in patients aged≤55 years and in patients with vascular invasion of liver cancer(P＜0.05).The anxiety score in the study group was lower than that in the control group,the patient satisfaction score in the study group was higher than that in the control group,and the differences between the two groups were statistically significant(both P＜0.05).No statistically significant difference in the incidence of adverse reactions existed between the two groups(P＞0.05).Conclusion Immersive VR technology can effectively reduce the degree of intraoperative pain in patients receiving TACE,especially in patients aged ≤55 years.Besides,VR technology can also reduce the anxiety degree of patients,and improve the degree of intraoperative patient satisfaction with nursing.

China has made remarkable advances in the field of organ donation and transplantation. However, with surging demands for organ transplantation services, there is still a large gap. Thus the Chinese development of organ donation and transplantation has a lot of catch-ups. The new Regulations on Human Organ Donation and Transplantation accorded with domestic conditions, culture and ethics. It specified that organ donation and transplantation should adhere to the general principle of "People Foremost & Life Primary" and strengthen the top-level designs of five operating systems of organ donation, acquisition & distribution, transplant clinical services, transplant quality control and supervising & optimizing. Upholding the protection of the rights and interests of both donors and recipients, it strengthened the supervision of the whole process of organ donation & transplantation, emphasized the importance of publicity & education of organ donation, provided a more solid legal guarantees for standardizing and promoting organ donation & transplantation and ushered in new opportunities for further developments of human organ donation & transplantation.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To evaluate the residual risk (RR) of transfusion transmitted HIV (TT-HIV) after the implementation of nucleic acid amplification test (NAT) in blood screening test among blood centers in China.Methods:The data of blood donors and HIV infection markers from 2017 to 2020 were collected from 28 blood centers via the Platform of Comparison of blood establishments Practice in Chinese Mainland. The new infection rate/window period mathematical model was used for two types of blood screening strategies, namely, two rounds ELISA plus individual NAT take turn with pooling NAT (2ELISA+ ID-NAT/MP-NAT) and two ELISA plus one round pooling NAT (2ELISA+ MP-NAT), and the RR of HIV infection was estimated also based on first donors (FDs) and repeated donors (RDs) in different blood donation years. T-test analyses were conducted for comparing TT HIV RR among FDs and RDs in different blood donation years with two blood screening strategies, and the variation trend of RR in HIV test was observed.Results:From 2017 to 2020, the RR of FDs in 2ELISA+ ID-NAT/MP-NAT blood screening strategy was 2.869/10 6 person-year, 3.795/10 6 persons-year, 3.879/10 6 person-year, and 2.890/10 6 person-year respectively. The RR of RDs was 1.797/10 6 person-year, 1.502/10 6 person-year, 1.857/10 6 person-year, and 1.483/10 6 person-year respectively. Significant difference exists between RR of FDs and RDs, with F=9.898 and p<0.05. In 2ELISA+ MP-NAT strategy, the RR of FDs was 3.508/10 6 person-year, 1.868/10 6 person-year, 2.204/10 6 person-year, and 1.765/10 6 person-year respectively. The RR of RDs was 0.948/10 6 person-year, 0.926/10 6 person-year, 0.748/10 6 person-year, and 0.682/10 6 person-year respectively. Statistical difference existed between RR of FDs and RDs, with F=17.126 and P<0.05. There was no significant difference between the RR of FDs in these two strategies with F=3.493 and P>0.05, while there was a difference between the RR of RDs in these two strategies with F=24.516 and P<0.05, and a difference between the RR of total donors (TDs) in these two strategies F=20.216 and P<0.05. Conclusions:The RR of TT HIV significantly decreased after the introduction of NAT into blood test among blood centers in China. There were some differences in the RR of HIV testing among different blood screening strategies. There could be significant differences in the RR of HIV testing among different groups of blood donors. Compared with FDs, RDs is the low risk group for HIV.

Objective:To investigate the unqualified hepatitis C virus (HCV) detection result of blood donors from the served area of blood institutions.Methods:The data related to HCV markers detected of the first and repeat blood donors were collected from the system of practice comparison for the Chinese mainland blood institutions from 2017 to 2021. The anti-HCV reactive rate and the rates of anti-HCV negative but HCV-RNA reaction and all the relationship between rates and the annual, regional and different blood donors were statistically analyzed.Results:During 2017-2021, the number of anti-HCV reactive per 100 000 blood donors decreased from 444.3 to 250.44 in the served area of 22 blood institutions ( χ2=49.677, P<0.05). The number of HCV RNA detected positive per 100 000 anti-HCV negative increased from 0.69 to 2.05 year by year, but there was no statistical significance ( χ2=0.643, P>0.05). The anti-HCV unqualified rate was significantly different among regions ( χ2=3 260.283, P<0.05). The anti-HCV unqualified rate of the first blood donors was significantly higher than that of the repeated blood donors ( F=130.993, P < 0.05). The annual number of HCV RNA detected positive per 100 000 anti-HCV negative blood samples from donors ranged from 0 to 17.28. Conclusions:The anti-HCV unqualified rate of blood donors in the served area of 22 blood institutions decreased year by year. Compared with repeated blood donors, HCV infection should be emphasized in first-time blood donors. The implementation of HCV RNA test can detect out much more HCV infections and reduce the risk of transfusion transmitted infectious HCV.
