RESUMO

Background And Objectives: Chronic active Epstein-Barr virus disease (CAEBV) is a proliferative disease of EBV+ T or natural killer (NK) cells with an unclear pathogenesis. This study aimed to examine the frequency and exhaustion levels of lymphocyte subsets in patients with CAEBV to further investigate the pathogenesis. Methods: Using flow cytometry, we detected the frequency, expression levels of programmed cell death 1 (PD-1) and programmed death ligand 1 (PD-L1), and EBV infection status of peripheral T subsets and NK cells in patients with CAEBV and healthy individuals. Results: 24 patients and 15 healthy individuals were enrolled in this study. Patients showed notably higher expression levels of PD-1 and PD-L1 in peripheral T subsets and NK cells compared to healthy individuals (P < 0.05). EBV+ lymphocytes exhibited significantly higher PD-L1 expression levels than EBV- lymphocytes. Additionally, the frequency of effector memory T (Tem) cells was significantly increased in patients, and the PD-L1 expression level was positively correlated with the EBV load. Besides, helper T cell 2 (Th2) immune bias, also favoring EBV amplification, was found in patients, including increased Th2 cell frequency, enhanced response capacity, and elevated serum levels of associated cytokines. The distribution and PD-1 expression levels of peripheral T subsets returned to normal in patients who responded to PD-1 blockade therapy. Conclusions: The up-regulation of the PD-1/PD-L1 pathway of peripheral T and NK cells and Th2 immune predominance jointly promoted EBV replication and the development of CAEBV. PD-1 blockade therapy reduced the PD-1 expression level of lymphocytes and helped normalize the distribution of the T subsets.

RESUMO

The discovery of structurally distinct leads is imperative in modern agrochemical science. Inspired by eudistomins Y and the framework-related pharmaceuticals, aryl heteroaryl ketone was drawn as a common model intriguing the design and divergent synthesis of 14 kinds of heteroaryl ketones aligned with their oxime derivatives. Antifungal function-oriented phenotypical screen protruded benzothiazolyl-phenyl oxime 5a as a promising model, and the concomitant modification led to benzothiazolyl oxime 5am (EC50 = 5.17 µM) as a superior lead than fluoxastrobin (EC50 = 7.54 µM) against Sclerotinia sclerotiorum. Scaffold hopping of the phenyl subunit identified benzothiazolyl-pyridyl oxime as a novel antifungal scaffold accompanied by acquiring oxime 5bm with remarkable activity (EC50 = 3.57 µM) against Pyricularia oryzae. Molecular docking showed that candidate 5am could form more hydrogen bonds with the amino acid residues of actin than metrafenone. This compound also demonstrated better curative efficacy than that of fluoxastrobin and metrafenone in controlling the plant disease caused by S. sclerotiorum. These results rationalize the discovery of antifungal candidates based on aryl heteroaryl ketone.

RESUMO

As an important bioactive molecular backbone, drimane meroterpenoids have drawn a great deal of attention from both pharmacologists and chemists. Inspired by the prevalidated success of conformational restriction in the discovery of novel pharmaceutical leads, two distinct tetracyclic drimane meroterpenoids, (-)-pelorol and (+)-aureol, were synthesized from the inexpensive starting material (-)-sclareol through 10 and 8 steps with 5.6% and 5.4% overall yield, respectively. The mild conditions, operational facility, and scalability enabled the expedient synthesis and biological exploration of not only natural products themselves but also their mimics. The first agrochemical exploration showed (-)-pelorol and (+)-aureol possessed good antifungal activity against Rhizoctonia solani, with EC50 values of 7.7 and 6.9 µM, respectively. This revealed that tetracyclic drimane meroterpenoids are valuable models for antifungal lead discovery.

RESUMO

Intermittent fasting (IF), which involves prolonged fasting intervals accompanied by caloric restriction (CR), is an effective dietary treatment for obesity and diabetes. Although IF offers many benefits, it is difficult to determine whether these benefits are the consequences of CR. Every-other-day feeding (EODF) is a commonly used IF research model. This study was designed to identify factors, in addition to CR, responsible for the effects of EODF and the possible underlying mechanisms. Diabetic db/db mice were divided into three groups: ad libitum (AL), meal feeding (MF), and EODF. The MF model was used to attain a level of CR comparable to that of EODF, with food distribution evenly divided between 10:00 a.m. and 6:00 p.m., thereby minimizing the fasting interval. EODF yielded greater improvements in glucose homeostasis than MF in db/db mice by reducing fasting glucose levels and enhancing glucose tolerance. However, these effects on glucose metabolism were less pronounced in lean mice. Furthermore, ubiquitination of the liver-specific glucocorticoid (GC) receptor (GR) facilitated its degradation and downregulation of Kruppel-like factor 9 (KLF9), which ultimately suppressed liver gluconeogenesis in diabetic EODF mice. Although GR and KLF9 might mediate the metabolic benefits of EODF, the potential benefits of EODF might be limited by elevated serum GC levels in diabetic EODF mice. Overall, this study suggests that the metabolic benefits of EODF in improving glucose homeostasis are independent of CR, possibly because of the downstream effects of liver-specific GR degradation.

RESUMO

Gynecological malignancy remains a prevalent cause of mortality among women. Chronic cancer pain, as a severe complication of malignancy and its therapies, accounts for a substantial burden of physical and psychological distress in affected patients. Accordingly, early identification, assessment, and standardized management of such pain are crucial in the prevention or delay of its progression. In the present review, we provide a comprehensive overview of the pathological factors that contribute to pain in patients with gynecological malignancy while highlighting the underlying mechanisms of pain in this population. In addition, we summarize several treatment modalities targeting pain management in gynecologic cancer patients, including surgery, radiotherapy, and chemotherapy. These interventions are crucial for tumor elimination and patient survival. Chronic cancer pain exerts a significant impact on wellbeing and quality of life for patients with gynecologic cancer. Therefore, our review emphasizes the importance of addressing this pain and its psychological sequelae and advocates for a multidisciplinary approach that encompasses nursing and psychological support. In summary, this review offers valuable insights into the pathological factors underlying pain, reviews pain management modalities, and stresses the critical role of early intervention and comprehensive care in enhancing the quality of life of these patients.

RESUMO

Osteogenic sarcoma (OS), one of the mesenchymal tumors with a high degree of malignancy, mainly occurs in the metaphysis of the long bones and around the knee joints in children and adolescents. The poor diagnosis in patients with OS can be attributed to the lack of early clinical symptoms, although the growth of tumor mass gradually results in severe pain and systemic symptoms. The mechanisms underlying the pathogenesis of OS are not fully understood. Thus, identifying early diagnostic biomarkers and novel targets involved in the progression of OS is of critical significance in the management of OS. CircRNA is a class of non-coding RNAs characterized by the close-loop structure and increased stability, which are implicated in the regulation of cell proliferation, differentiation, migration, and apoptosis. Moreover, circRNAs also play significant roles in aging and chronic disorders, such as cancer and cardiovascular diseases. Accordingly, we reported the upregulation of circRNA-CIRH1A in OS tissues and cell lines. Silencing circRNA-CIRH1A in OS cell lines (U2OS, HOS, Saos-2, and MG-63) could inhibit the cell proliferation, invasion, migration, and apoptosis, which was also validated in xenograft tumorigenesis mouse model. We further demonstrated that circRNA-CIRH1A sponged miR-1276, which subsequently disrupted the effect of miR-1276 on PI3K/AKT and JAK2/STAT3 signaling pathways. Together, our study revealed the oncogenic role of circRNA-CIRH1A in OS, and identified miR-1276/ PI3K-AKT and JAK2-STAT3 signaling axis as the key downstream mediators of circRNA-CIRH1A.

RESUMO

Lung cancer is a common clinical malignant tumor, and the number of new lung cancer patients is increasing year by year. With the advancement of thoracoscopy technology and equipment, the scope of application of minimally invasive surgery has expanded to almost all types of lung cancer resection, making it the mainstream lung cancer resection surgery. Single-port thoracoscopic surgery provides evident advantages in terms of postoperative incision pain since only a single incision is required, and the surgical effect is similar to those of multi-hole thoracoscopic surgery and traditional thoracotomy. Although thoracoscopic surgery can effectively remove tumors, it nevertheless induces variable degrees of stress in lung cancer patients, which eventually limit lung function recovery. Rapid rehabilitation surgery can actively improve the prognosis of patients with different types of cancer and promote early recovery. This article reviews the research progress on rapid rehabilitation nursing in single-port thoracoscopic lung cancer surgery.

RESUMO

OBJECTIVES: Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of EBV-associated T-or NK-cell lymphoproliferative diseases. It is a disease with poor outcome. Almost all current therapies are ineffective except of allogeneic hematopoietic stem cell transplantation. METHODS: We investigated the efficacy and safety of programmed death 1 (PD-1) blockade (Sintilimab), combined with lenalidomide, which is an immunomodulatory drug, in an open-label, single-center, prospective study involving CAEBV patients. PD1 blockade 2mg/kg was given every two weeks by intravenous infusion on day 1, and lenalidomide 5mg (age<18 years)/10mg (age ≥ 18 years) was given orally once a day on day 1-14. RESULTS: As of Nov 15, 2020, 34 patients were enrolled. As of the Feb 1, 2021 analysis cut-off date, 24 cases completed at least 3 courses and were assessed for efficacy. The overall response rate is 54.2% (13/24, 45.8% complete response; 8.3% partial response). EBV-DNA copies in PBMC decreased significantly (p = 0.002). The proportion of CD8+T cells in lymphocytes increased (p = 0.007). The comparative analysis between response group and non-response group showed the proportion of Effector Memory CD8+ T cells and cytokines of CTLs activation (IFN-γ, CD27, CD30, MIG, IP-10) increased significantly in Response-group after treatment. Whole-exome sequencing generated from peripheral blood and saliva samples reveal that Non-Response group had a higher somatic mutational load of copy number variation in background. With a median follow-up time of 17.8 months, 22 of 24 patients were alive with an estimated survival probability of 91.3% at 1 year. All 34 patients were assessed for safety evaluation. The possible drug-related adverse events were reported in 17 (50%) patients. CONCLUSIONS: PD-1 blockade combined with lenalidomide was an effective and safe therapy for CAEBV patients. The significant therapeutic effect and the different characteristics between response and non-response group, provides a possible predictive value for CAEBV treatment option.

RESUMO

With triethylamine as a vinylene source, a convenient protocol for the regioselective synthesis of ß,γ-nonsubstituted 2-arylquinolines from aldehydes and arylamines has been accomplished. The deaminative cyclization is also extended to long-chain tertiary alkylamines, enabling diverse alkyl groups to be concurrently installed into the pyridine rings. This process demonstrates a new conversion pathway for the simultaneous dual C(sp3)-H bond functionalization of tertiary amines, wherein the transient acyclic enamines generated in situ undergo the Povarov reaction.

RESUMO

Objectives: To investigate the benefits of Sufu medical chitosan hydrogel dressing(Sufu) in the prevention and control of radiation skin damage during radiotherapy for cervical cancer as a combined modality. Methods: Ninety-seven cervical cancer patients who underwent radiotherapy at the Cancer Hospital of China Medical University between May 2017 and November 2018 were recruited according to given inclusion and exclusion criteria. The patients were assigned to a control group (n=48, washing the perineal area with normal saline) and an observation group (n=49, application of Sufu onto the site of radiotherapy in addition to washing the perineal area with normal saline). The treatment regimens for the two groups continued until the end of radiotherapy. A comparison of the RTOG (Radiation Therapy Oncology Group) grading of acute radiation-induced skin reactions (ARISRs), pain intensity (measured by the verbal rating scale (VRS)) and post-treatment wound healing was drawn between the two groups. Results: In the observation group, 81.6% (40/49) of the patients had radiation dermatitis, which was significantly lower than the incidence rate (95.8%, 46/48) in the control group (P <0.05). The observation group was at higher risk of radiation dermatitis when given a high radiation dose, while the control group was more likely to have radiation dermatitis when administered with a moderate radiation dose (P <0.05). The median time of occurrence of pain and the median time of onset of skin reactions were significantly later in the observation group as compared with the control group (P <0.05, respectively). In the observation group, the pain relief rate was 92.50% at Day-3, and the wound healing rate was 95.0% at Day-7, significantly higher than in the control group (73.9% and 80.4%) (P <0.05, respectively). Conclusions: During radiotherapy for cervical cancer, Sufu can effectively prevent and control radiation-induced skin and mucous membrane damage, delay the onset of radiation dermatitis and substantially reduce the incidence rate, relieve radiation dermatitis and pain and promote wound healing.

RESUMO

OBJECTIVE: To explore the etiology of wound infections in patients with open tibia and fibula fractures and the treatment effects. METHODS: In this retrospective study, a total of 76 patients with open tibia and fibula fractures were included in this research. These patients were divided into the control group (n=38) and the observation group (n=38) according to the treatment methods for wound infection. The distribution and drug resistance of pathogenic bacteria in wound infections were analyzed. Clinical effects, time for body temperature returning to normal, time for disappearance of exudates, time for clearance of pathogenic bacteria, recovery effects and patients' satisfaction rate were also compared between two groups. RESULTS: A total of 152 strains of pathogenic bacteria were separated. The main pathogenic bacterium was Acinetobacter baumannii, accounting for 30.92% (47/152). Pathogenic bacteria were demonstrated to be highly sensitive to vancomycin and imipenem. The proportion of wound healing by first intention and the Johner-Wruhs scores in observation group were significantly higher than those in control group, while recurrent infection rate, the time to restore normal body temperature, the time for exudates to disappear, the time to remove pathogenic bacteria, hospital stays and VAS scores in observation group were obviously shorter or lower than those in control group (all P<0.05). Moreover, the satisfaction rate of patients in the observation group was significantly higher than that in the control group (P<0.05). CONCLUSION: Understanding pathogenic characteristics and drug resistance of wound infection in patients with open tibia and fibula fractures is helpful to subsequent treatment. Comprehensive control measures should be taken to decrease incidence of wound infection.

RESUMO

Background: Numerous genetic studies have shown that genes are related to the pathogenesis of coronary heart disease (CHD). The main aim of this study was to confirm whether fibronectin type III domain containing 1 (FNDC1) polymorphisms correlate with the risk of CHD. Methods: In this study, in order to assess the association between three FNDC1 single nucleotide polymorphisms (SNPs) and the risk of CHD, we conducted a case-control study involving 630 patients with CHD and 568 healthy controls using Agena MassARRAY (Agena Bioscience, San Diego, CA, USA). Genotype distribution in case and control groups was analyzed by Chi square test. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression models adjusted for age, sex, smoking, and alcohol consumption to assess the correlation between SNPs and CHD risk. Results: Our results indicated that FNDC1-rs420137, -rs386360, and -rs7763726 played important roles in enhancing the risk of CHD. Subgroup analysis revealed that rs420137 increased the susceptibility to CHD in males, smokers, and patients aged ≤62 years. Rs360 had an increased risk of CHD in males, patients at aged ≤62 years, smokers, and non-drinkers. Furthermore, the association of rs7763726 with increased CHD risk was also observed in males, patients aged ≤62 years, smokers, and drinkers. Last but not least, these three SNPs we selected were protective factors against hypertension in CHD individuals. Conclusion: Our research suggest that FNDC1-rs420137, -rs386360, and -rs7763726 variants may be regarded as novel biomarkers for predicting CHD risk and other specific mechanisms of action of CHD need to be further studied.

RESUMO

OBJECTIVE: The red blood cell distribution width to platelet ratio (RPR) is known to reflect systemic inflammation. This study aimed to explore the predictive value of RPR for disease activity and adverse pregnancy outcomes (APOs) in pregnant women with systemic lupus erythematosus (SLE). METHODS: We retrospectively evaluated case data of all pregnant women with SLE managed at the First Affiliated Hospital of Zhengzhou University from January 2014 to March 2017. Correlations between RPR and SLE clinical disease activity, organ involvement, and maternal complications were analysed. Changes in the RPR and erythrocyte sedimentation rate (ESR) were observed before and after treatment. A receiver operating characteristic (ROC) curve was used to predict disease activity and APOs based on RPR. RESULTS: A total of 118 patients were enrolled, including 77 in the disease-active group and 41 in the disease-inactive group. The live birth rate was significantly higher in the disease-inactive group than in the disease-active group (P < 0.001). Compared to the disease-inactive group, the number of patients with elevated RPR, anti-dsDNA antibody level, and ESR was significantly higher in the disease-active group, whereas their platelet-lymphocyte ratios and complement 3 and 4 levels were significantly lower. The disease-active group was more likely to experience APOs (P < 0.001), mainly due to premature birth, low birth weight, and pregnancy loss. The ROC curve indicated that RPR had an effect on disease activity and APOs. CONCLUSION: RPR can be used as a predictor of disease severity and APOs in pregnant women with SLE. Key Points • RPR positively correlated with SLEDAI; patients with elevated RPR have higher disease activity, more organ, and more maternal complications. • Monitoring RPR could better predict disease activity in pregnant patients with SLE and reduce the incidence of maternal complications and APOs.

RESUMO

OBJECTIVE: To evaluate the prognostic value of circulating tumor cells (CTCs) in ovarian cancer. METHODS: Chinese databases (Wanfang, Cqvip, CNKI) and English databases (PubMed, Web of Science, Embase, SinoMed, Cochrane Library) were retrieved to collect relevant studies on CTCs evaluation of ovarian cancer prognosis. Data were extracted to analyze the effect of CTCs on the overall survival (OS) and progression-free survival (PFS) of patients, and a meta-analysis was performed using Stata 15 software. RESULTS: Nineteen studies were included in this meta-analysis. The results showed that ovarian cancer patients with positive CTCs had a shorter OS and higher death rate, (HR=1.57, 95% CI: 1.30, 1.84), a shorter PFS and an increased risk of disease progression (HR=1.29, 95% CI: 1.04, 1.54) compared with patients with negative CTCs. Subgroup analysis showed that the HRs for death and disease progression were higher in CTCs-positive patients after treatment than those patients with negative CTCs (P<0.05). CONCLUSION: CTCs detection has a high application value in the prognosis assessment of ovarian cancer.

RESUMO

Alzheimer's disease (AD) is characterized by progressive cognitive decline, which is considered as the most common form of dementia in the elderly. Recently, it is suggested that impaired cerebrovascular function may precede the onset of AD. Claudin-5, which is the most enriched tight junction protein, has been reported to prevent the passage of damaging material at the blood-brain barrier. However, whether claudin-5 impacts AD has no direct evidence. We found a decrease level of claudin-5 in the hippocampus of AD and elder mice. And intravenous injection of claudin-5 improved learning and memory ability in these mice, while knockout of the protein led to impaired learning and memory and long-term potentiation in adult control mice. Furthermore, the effects of claudin-5 are mediated by suppressing inhibitory GABAergic neurotransmission. Our results suggest benefit effects of claudin-5 on learning and memory, which may provide a new treatment strategy for AD.

RESUMO

Forensic science is crucial for the administration of justice and case investigation. In China, political-legal organizations, including the courts, public security, procuratorate, and judicial administration, developed their own forensic practices before 2004. As a result, the frequent and repeated appraisals undermined judicial authority and credibility. Thus, a law was published in 2005 to improve the uniform forensic management system by the Standing Committee of the National People's Congress, leading to the establishment of the Forensic Administration of the Ministry of Justice in 2006. During this process, the increased accreditation and interflow highlighted the role of consensus in forensic standards for forensic service providers to avoid uncertainty regarding the methods used and interpretation of results. In 2017, a policy document was promulgated again to strengthen the importance of the uniform standards, which also proposed to establish a new national technical committee for the standardization of forensic science by the General Office of the State Council. In 2018, despite the continuing problems concerning uniformity, the Forensic Administration of the Ministry of Justice was merged into the Public Legal Services Administration. Yet, there is still a long way to go for the national technical committee for the standardization of forensic science. This paper analyses the evolution of forensic standards internationally and nationally, discusses the existing problems, and proposes relative solutions. Moreover, it discusses the future of standards development with the deepening of the reformation of both the national standardization and judicial system.

RESUMO

BACKGROUND: Chronic active Epstein-Barr virus infection (CAEBV) disease is sometimes associated with an aggressive clinical course, such as hemophagocytic lymphohistiocytosis (HLH). To explore the risk factors and predict the risk of CAEBV infection progressing to HLH, a retrospective research study was conducted. METHODS: We retrospectively reviewed the medical records of 187 CAEBV-infected patients who were admitted to our center between January 2015 and December 2020. The patients were followed up until May 2021. The patients were divided into a progression-to-HLH group and a no-progression-to-HLH group. Demographic, clinical and laboratory data were collected for each patient. RESULTS: Among the 121 CAEBV-infected patients who fulfilled the study's inclusion criteria, 48 (30.7%) patients did not progress to HLH, and 73 (60.3%) patients progressed to HLH. The median time from CAEBV infection to progression to HLH was 14 months, and the cumulative incidence rate of HLH increased as the duration of follow up increased (24.9, 47.3, 55.1, and 85.2% at 1, 3, 5, and 10 years, respectively). Multivariate analyses showed that the independent risk factors for CAEBV progression to HLH were plasma EBV-DNA load (OR = 3.239, 95% CI 1.219-8.603, P = 0.018), Platelet count (OR=0.991, 95%CI 0.985-0.998, P = 0.010), elevated alanine aminotransferase (OR=1.019, 95%CI 1.005-1.034, P = 0.009) and ≥2 of 3 lineages of cytopenia (OR=8.364, 95%CI 1.062-65.839, P = 0.044). The regression coefficients (ß) from the multivariate logistic model were used to construct a model for estimating the risk of CAEBV infection progressing to HLH. The discriminatory ability of the model was good, and the area under the receiver operating characteristic (ROC) curve (AUC) was 0.925. CONCLUSION: plasma EBV-DNA load, platelet count, elevated alanine aminotransferase and ≥ 2 of 3 lineages of cytopenia increase the risk of CAEBV infection progressing to HLH. A nomogram can be used to estimate the risk of CAEBV-infected patients progressing to HLH.

RESUMO

BACKGROUND: Pegylated liposomal doxorubicin (PLD) uses the hydrophilic layer of liposomes to reach the sweat on the skin surface or accumulate in the sweat glands, producing toxic free radicals and oxidative damage, resulting in hand-foot syndrome (HFS). Regional cooling can induce vasoconstriction to reduce the release of drugs in the limbs and reduce the accumulation of drugs in sweat glands; thus, decreasing the incidence and severity of HFS. AIM: To study the efficacy of cooling patches to prevent HFS caused by PLD in the short-term. METHODS: This is a retrospective cohort study. Female breast cancer patients (n = 101) who were treated with PLD in two breast wards at our department from February 2020 to February 2021 were enrolled in the study and were randomly divided into the cooling group (51 patients) and the control group (50 patients). Patients in the control group only received routine care, while the patients in the cooling group applied cooling patches, based on routine care, to the palm and back of the hands 15 min before chemotherapy infusion for 10 h. All patients took a corresponding dose of dexamethasone orally one day before chemotherapy, on the day of chemotherapy, and one day after chemotherapy. SPSS23.0 version was used to analyze the data in this study. The occurrence and severity of HFS was analyzed by the Mann-Whitney U test, and scores were analyzed by the Student's t test or Wilcoxon rank-sum test. A P value < 0.05 was regarded as statistically significant. RESULTS: In this study, neither group of patients developed Grade 3 HFS. In the control group, the incidence of Grade 1 HFS and Grade 2 HFS was 38% and 2%, respectively. However, in the cooling group, only one person developed Grade 1 HFS (2%), and none of the patients developed Grade 2 HFS. These findings showed that cooling patches can effectively reduce the frequency and severity of HFS (P < 0.0001) in the short-term. Before the fourth chemotherapy cycle, although general self-efficacy scale scores in the cooling group were low, they were still significantly higher than those in the control group (17.22 ± 5.16 vs 19.63 ± 6.42, P = 0.041). Compared with the control group, the mean Hand-Foot Skin Reaction and Quality of Life Questionnaire score in the cooling group was significantly lower (18.08 ± 7.01 vs 14.20 ± 7.39, P = 0.008). CONCLUSION: Cooling patches can effectively reduce the frequency and severity of HFS caused by PLD in the short-term. In addition, it may help delay the decline in patients' self-efficacy.

RESUMO

In order to evaluate the postoperative nursing effect of artificial intelligence robot-assisted thoracic surgery, this study proposed the Da Vinci robot-assisted pulmonary lobotomy, from January to December 2014; 42 patients (15 males and 27 females, aged 33-69 years old) underwent lobectomy with the Da Vinci robot system in the chest hospital. A series of postoperative nursing was carried out. The surgical results showed that 42 patients with Da Vinci robot-assisted lobectomy had operation time of 62-225 min and blood loss of 70-300 mL. There was no intraoperative blood transfusion, the intraoperative central rate was maintained at 60-100 times/min, and the blood pressure was maintained at 90-140/60-90 mmHg. No patient was transferred to thoracotomy, and 2 patients were performed robotic wedge resection first, and then, robotic lobectomy was performed after malignant tumor was confirmed by freezing results, with relatively light postoperative pain, no infection, beautiful wound, and smooth recovery and discharge. Robot-assisted lobectomy is a new technique with advantages of less trauma, less pain, faster recovery, and safer and more thorough lymph node dissection.

RESUMO

OBJECTIVE: To evaluate the influence of high-quality care on the psychological well-being, the postoperative complications, and patient satisfaction following a radical mastectomy. METHODS: One hundred and eighteen breast cancer patients who underwent radical mastectomies from February, 2017 to May, 2019 in the Cancer Hospital of China Medical University were enrolled. Among them, 56 patients treated with regular care were included in the regular group, while the other 62 patients who underwent high-quality care were included in the high-quality group. The postoperative recoveries and complications were compared between the two groups. The visual analogue scale (VAS), the disabilities of the arm, shoulder and hand (DASH) questionnaire, the self-rating anxiety scale (SAS), the self-rating depression scale (SDS), the quality of life (QOL) assessment scale, and a patient satisfaction questionnaire were used to evaluate the degrees of pain, the upper limb recovery, the negative emotions, the QOL, the patient satisfaction and the two-year survival rate, respectively. RESULTS: The ambulation times, the regression times of upper limb swelling, and the hospital stays in the high-quality group were remarkably shorter than they were in the regular group (P<0.05). The postoperative complications were less frequent in the high-quality group (P<0.05). The VAS scores in the high-quality group were lower than they were in the regular group at 1, 3, and 5 days after surgery, and the DASH scores in the high-quality group were lower at 1 month after discharge (P<0.05). The high-quality group showed lower SAS and SDS scores and higher QOL and patient satisfaction than the regular group (all P<0.05). There was no difference in the two-year survival rates between the two groups after the intervention (P>0.05). CONCLUSION: High-quality care following a radical mastectomy contributes to postoperative recovery, the relief of negative emotions, the reduction of complications, as well as the enhancement of QOL and patient satisfaction, so it is worthy of clinical promotion.
