This article summarizes the current research status of health-related quality of life (HRQOL) in sepsis patients after discharge, including the current states of short-term and long-term HRQOL, influencing factors, and interventions. Recent studies have shown that both short-term and long-term HRQOL of sepsis patients after discharge are suboptimal. Given the numerous and long-lasting factors that affect HRQOL, it is recommended that individualized nursing interventions targeting these factors be implemented in clinical practice. Further research should explore effective methods to improve the HRQOL of sepsis patients.

Objective:This article analyzed the current situation, similarities and differences and main problems of the registration and management systems of innovative medical devices in China and the United States.Methods:This article summarized the requirements and policies for the registration management of innovative medical devices in China and the United States, as well as the development and differences of the registration of innovative medical devices in China and the United States, and the main problems in the registration management of innovative medical devices in China.Results:At present, the development level of medical device industry in China and the United States was different, facing different development problems, and there were differences in the access standards and management methods of innovative medical devices. The registration management system established for innovative medical devices in China was gradually improving, and to a certain extent, it had promoted the enthusiasm of innovative product research and development and registration applications, but there were also problems such as unclear innovation evaluation scales, insufficient early intervention of review resources, and insufficient utilization of post-marketing data.Conclusions:Drawing on the beneficial experience of breakthrough device registration management in the United States, we will improve the registration management system for innovative products and shorten the review and approval cycle by clarifying the identification criteria for innovative medical devices, promoting the placement of review resources in the R&D stage, and further strengthening the use of post-marketing data and regulatory scientific research.

Purpose: The interval between neoadjuvant chemotherapy (NAC) and surgery for locally advanced breast cancer (LABC) remains controversial. At the same time, the prognostic effect of delayed surgery in patients with poor responses is currently unclear. Methods: Data was collected from patients who had poor responses to NAC and underwent modified radical surgery from January 2013 to December 2018. The interval from completion of NAC to surgery was divided into two groups: a longer (greater than four weeks) or shorter (four weeks or less) interval. The associations of these interval groups with overall survival (OS) and recurrence-free survival (RFS) were evaluated by multivariable Cox models adjusting for the existing prognostic factors. Propensity score matching (PSM) was used to minimize election bias. Results: A total of 1,229 patients (mean age, 47.2 ± 8.9 years; median follow-up duration, 32.67 [6.57–52.63] months) were included. The 5-year OS rates were 73.2% and 60.8% in the shorter (n = 171) and longer interval group (n = 1,058), respectively, while the 3-year RFS rates were 80.8% and 71.7%, respectively. In multivariate Cox analysis, the longer interval was associated with an increased risk of mortality (hazard ratio [HR], 1.43; 95% confidence interval [CI], 1.01–2.02; p = 0.046) and recurrence (HR, 1.50; 95% CI, 1.12–1.99; p = 0.006).There was an interaction between the molecular subtype and the surgery interval for OS (pinteraction = 0.014) and RFS (pinteraction = 0.027). After PSM, no significant difference in OS (p = 0.180) and RFS (p = 0.069) was observed between the two groups. Conclusion Among LABC patients with a poor response, those with a longer interval between NAC and surgery had worse OS and RFS. The results indicate that these patients should receive modified radical surgery timely, which may in turn improve their prognosis.

This paper reported a case of severe COVID-19 in the recovery stage with acute lymphoblastic leukemia treated by integrated traditional Chinese and western medicine， with the intention of shedding light on the clinical diagnosis and treatment of similar conditions. The patient， who had acute lymphoblastic leukemia， developed COVID-19 infection during the bone marrow suppression period after chemotherapy. Treatment with western medicine was mainly anti-infection， symptomatic management， and supportive care. During the recovery stage， considering the patient's chemotherapy history and disease progression， the overall syndrome was identified as deficiency of both qi and yin and binding of phlegm and blood. Based on the “state-target” combined treatment strategy， herbal prescriptions were selected and modified to address the “deficiency state”， “disease target”， and “symptom target”. In addition to western medicine， the patient was administered with Shengmai Powder （生脉散） and Compound Zhebei Granules （复方浙贝颗粒） in its modifications to boost qi， nourish yin， and reinforce healthy qi， nourish and cool the blood， ultimately achieving satisfactory therapeutic effects.

Objective:To evaluate the accuracy of the domestic "Skywalker" surgical robot in implementing personalized lower limb alignment reconstruction scheme in total knee arthroplasty (TKA) and the short-term clinical outcome of robotic assisted TKA.Methods:From September 2020 to January 2021, the data of patients who received surgical robot assisted TKA in 5 clinical centers in China (Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Southwest Hospital affiliated to Third Military Medical University, The Affiliated Hospital of Qingdao University, The First Affiliated Hospital of Chongqing Medical University and Yantai Yuhuangding Hospital, and Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine was the group leader) were prospectively collected and retrospectively analyzed. There were 24 males and 82 females with an average age of 67.6±7.3 years, (range 45-80 years); Average body mass index 26.42±4.31 kg/m 2, all the operation were performed by "Skywalker" surgical robot system according to preoperative design based on CT. The operation time, intraoperative blood loss, hospitalization days and postoperative complications were recorded, and the imaging indexes including hip-knee-ankle (HKA), lateral distal angle of femur (LDFA) and medial proximal angle of tibia (MPTA) measured before and after the operation, implant model indexes (preoperative planning implant model and postoperative implant model) and short-term clinical efficacy indexes [Western Ontario and McMaster Universities (WOMAC) osteoarthritis index] pain score, stiffness score, joint function score, total score and SF-12 score before and 3 months after the operation) were compared. Results:The average follow-up period was 109.60±9.80 d, (range 95-143 d). The average operation time of 106 patients was 105.30±23.22 min; The average intraoperative blood loss was 141.70±58.33 ml; The average length of hospitalization was 5.82±2.80 d. One patient had ischemic stroke after operation, and one patient had abnormal liver function after operation. According to the judgment of the investigator, all of them were not related to the operation. The actual angle error is the difference between the preoperative planning angle and the postoperative measurement angle. The absolute error of 99.1% (105/106) of the HKA angle was within 3°, 90.8% (69/76) of LDFA, 98.7% (75/76) of the MPTA. In 45 patients in one center where data were available, the actual implant models used in all patients were consistent with the preoperative planning size, and there were only differences in version selection such as Asian condyle. WOMAC pain score, joint function score, total score was improved from 7.34±2.85, 25.10±9.85, 34.75±13.02 to 3.34±2.66, 14.68±9.64, 18.66±13.49 before and after operation, respectively, which were statistically significant ( P<0.001) and SF-12 physiological score and psychological score were improved form 27.24±6.42, 30.68±8.26 to 38.83±5.74, 39.36±7.85 before and after operation, respectively, which were statistically significant ( t=7.33, P<0.001; t=4.53, P=0.043). Conclusion:Domestic surgical robot system "Skywalker" can assist the surgeon to achieve accurate and personalized reconstruction of lower limb alignment and achieve satisfactory short-term clinical outcomes. The long-term clinical outcomes of personalized reconstruction and survival rate of implant still need to be further studied.
