Antibody-drug conjugates （ADCs） are a novel class of anti-tumor agents composed of a targeted monoclonal antibody， a cytotoxic drug， and a linker connecting the two. They combine the high specificity of antibodies with the potent cytotoxicity of chemotherapeutic agents. Triple-negative breast cancer （TNBC） is characterized by high aggressiveness， elevated risks of recurrence and metastasis， and poor prognosis， largely due to the lack of effective therapeutic targets. This review summarizes the research progress of ADCs in the treatment of TNBC. It has been found that ADCs targeting human epidermal growth factor receptor 2 （such as trastuzumab deruxtecan）， trophoblast cell surface antigen 2 （such as sacituzumab govitecan and datopotamab deruxtecan）， zinc transporter LIV-1 （such as ladiratuzumab vedotin）， HER-3 （such as patritumab deruxtecan）， epidermal growth factor receptor （such as AVID100）， and glycoprotein non-metastatic melanoma protein B （such as glembatumumab vedotin） have all demonstrated promising therapeutic effects against TNBC. Despite challenges including acquired resistance and treatment-related toxicities， ADCs are undoubtedly reshaping the therapeutic landscape for TNBC and are expected to occupy a more central position in TNBC treatment in the future.

Objective:To systematically integrate qualitative researches on the financial toxicity experience of cancer patients, so as to provide reference for formulating intervention strategies for financial toxicity in cancer patients.Methods:Qualitative studies on financial toxicity experience of cancer patients were searched in Web of Science, PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, Wanfang data, and China Biology Medicine disc, with a search period from database establishment to August 31, 2023. The quality of the included literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence Based Health Care Center in Australia. The aggregation integration method was used to integrate the results.Results:A total of 12 articles were included, and 68 research results were extracted and categorized into 15 new categories. Four integrated results were obtained, including anxiety and stress under financial difficulties, relying on family members to start a new in adversity, and dancing together with treatment and life to write a new article, and great expectations for the future.Conclusions:Pay attention to the financial toxicity of cancer patients, actively seek response strategies, and bring benefits to cancer patients.

Objective:To investigate the differences of clinical data and pathological changes in patients with primary IgA nephropathy (IgAN) with different blood types.Methods:The clinical and pathological data of patients with primary IgAN diagnosed by renal biopsy in the People's Hospital of Ningxia Hui Autonomous Region from May 2016 to May 2021 were collected. They were divided into groups A, O, B and AB according to blood group. The clinical manifestations and pathological changes of the four groups during renal biopsy were analyzed.Results:A total of 258 patients with primary IgAN were included, including 87 cases of type A, 74 cases of type O, 72 cases of type B and 25 cases of type AB. The male to female ratio was 1.34∶1, and the median age was 36 (29, 47) years old. There was no significant difference in age, sex, blood pressure, hemoglobin and renal function among the four groups (all P>0.05). Neutrophil gelatinase-associated lipocalin (NGAL) in patients with type A and B was higher than other groups (all P<0.05). There were no significant differences in mesangial cell hyperplasia (M), capillary cell hyperplasia (E), glomerular segmental sclerosis (S), renal tubule atrophy/interstitial fibrosis (T), crescent body (C) lesions and proportion of sclerosed glomeruli among the four groups (all P>0.05). Subgroup analysis by gender showed that the hemoglobin, uric acid and creatinine of male patients were higher than those of female patients (all P<0.05), but the estimated glomerular filtration rate (eGFR) and urinary protein had no statistical significance (all P>0.05). Women with blood type A and O were heavier than men under microscope. The pathological manifestations of M, E, S and C lesions in women with type A blood were heavier than those in men, and S and T lesions in men with type B blood were heavier than those in women. There was no significant difference in the general baseline data, inflammation and kidney indexes between the four groups of men and women (all P>0.05). Pathologically, the M lesions of men with B blood group were more severe than those of other blood groups, while the S and T lesions of women with B blood group were less severe than those of other blood groups. Conclusions:The clinical and pathological manifestations of IgAN women with type A are heavier, the pathological manifestations of IgAN women with type B are lighter, but the pathological lesions of IgAN men with type B are heavier.

Objective:To understand the incidence of sleep disorder in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients before antiviral therapy, and to explore its risk factors.Methods:200 newly treated HIV/AIDS patients who visited the Eighth Affiliated City Hospital of Guangzhou Medical University from January to June 2016 were randomly selected. According to the Pittsburgh Sleep Quality Index (PSQI), they were divided into a good sleep group and a Sleep disorder group; The influencing factors of sleep disorder in HIV/AIDS patients were analyzed by univariate analysis and multivariate logistic regression.Results:The incidence of Sleep disorder in 200 HIV/AIDS patients before antiviral therapy was 22.5%(45/200); CD4 + T cell count was (414.13±202.16)/μl; 29%(58/200) of patients had CD4 + T cell counts<200/μl. There were significant differences in CD4 + T cell count and the proportion of patients with syphilis infection, comorbidity anxiety and comorbidity depression between the good sleep group and the Sleep disorder group (all P<0.05). Multivariate logistic regression analysis showed that syphilis infection ( OR=4.606; 95% CI: 1.973-10.752; P<0.001), comorbidity anxiety ( OR=2.496; 95% CI: 1.086-5.737; P=0.031) and comorbidity depression ( OR=2.087; 95% CI: 0.915-4.760; P=0.040) were risk factors for sleep disorder in HIV/AIDS patients before antiviral treatment. Conclusions:The incidence of Sleep disorder in HIV/AIDS patients before antiviral therapy in Guangzhou is high, especially in patients with syphilis infection, comorbidity anxiety and comorbidity depression. The sleep disorder of HIV/AIDS patients should be assessed and detected early, and multiple interventions should be taken to improve sleep quality.

Objective:To investigate the risk factors and prognoses of cerebral venous sinus thrombosis (CVST) caused by pegasparaginase (PEG-Asp).Methods:A total of 252 children with acute lymphoblastic leukemia (ALL) were treated with PEG-Asp chemotherapy in our hospital from December 2016 to July 2021, including 8 children with CVST. The clinical manifestations, laboratory and imaging features, treatments and prognoses of these children with CVST caused by PEG-Asp were analyzed retrospectively.Results:(1) CVST occurred during induction chemotherapy in 4 children, during re-induction chemotherapy in 3 children, and during consolidation stage in one child. CVST occurred in two children who received PEG-ASP chemotherapy once, in one child who received PEG-Asp chemotherapy twice, and 5 children who received PEG-Asp chemotherapy more than twice. The median time between CVST occurrence and last treatment of PEG-Asp was 20.5 d. (2) The clinical manifestations included paroxysmal headache ( n=4), nausea or vomiting ( n=3), convulsions ( n=2) and persistent blurred vision ( n=1). (3) CVST appeared at the sigmoid sinus ( n=6), transverse sinus ( n=4) and superior sagittal sinus ( n=4), of which one child was complicated with hemorrhage in left frontal parietal and right parietal cortex, and one with reversible posterior encephalopathy syndrome; 8 children were not complicated with thrombus in other parts. (4) Some of the children were complicated with abnormal blood coagulation. When CVST occurred, fibrinogen level decreased in 3 children, anti-thrombin III level decreased in 2 children, and D-dimer level increased in 3 children. (5) Six children were treated with low molecular weight heparin (LMWH), of which, 4 were treated with rivasaban and one with warfarin sequentially. The total course of anticoagulation was 56 d. (6) The symptoms of 6 children disappeared after anticoagulation; Magnetic resonance venography (MRV) showed disappeared thrombus in 4 children and reduced thrombus range in 2 children. One child with intracranial hemorrhage did not use PEG-Asp anymore; 7 accepted PEG-Asp further during follow-up chemotherapy, of which one had CVST recurrence and the range of thrombus was reduced after anticoagulant therapy. Conclusions:When children with ALL develop unexplained neurological symptoms during PEG-Asp chemotherapy, CVST should be highly vigilant. Enhanced MRI and MRV should be performed for early diagnosis. Some children are complicated with abnormal blood coagulation, and LMWH, warfarin and rivasaban are effective. The prognosis is good and there are no sequelae. Most children accepted PEG-Asp again will not have CVST again.

OBJECTIVE To explore the influence of surgical history on chemotherapy -induced nausea and vomiting （CINV）. METHODS A retrospective case -control study was adopted ，with 824 patients undergoing chemotherapy as the object . A total of 27 items were collected ，including demographic data ，medical history data ，pre-chemotherapy data ，and chemotherapy treatment status. Logistic regression model was used to analyze the relationship between the history of surgery and the risk of CINV . The multiple models were constructed to correct potential confounding factors ，and subgroup analysis was performed on patients with surgical history . RESULTS The incidence of CINV was higher in patients with surgical history . The statistical result before adjustment was [OR＝1.72，95%CI（1.31，2.28），P＜0.001]；after adjusting potential confounding factors ，the statistical result was [OR＝1.78，95% CI（1.28，2.48），P＝0.001]. In the subgroup analysis ，the time between surgery and chemotherapy was different ， and the impact of surgical history on CINV was different ，and the results were statistically significant （P＝0.027）. The risk of CINV showed decreasing trend with the time ，and the results were statistically significant （P for trend ≤0.050）. Compared with patients who had not undergone surgery ，patients who had undergone surgery within one year had a higher risk of CINV [OR＝ 2.33，95%CI（1.52，3.59），P＜0.001]. CONCLUSIONS Patients with surgical history are more prone to CINV ，and the risk of CINV shows a downward trend in the length of time from surgery .

CONCLUSIONS ：Patients with the following conditions are more likely to experience CINV prevention ineffectiveness ，ie. single long-term chemotherapy ，application of chemotherapy plan with a higher risk of emesis ，history of chemotherapy-induced vomiting ，history of gastrointestinal diseases ， nausea and vomiting 24 hours prior to chemotherapy ，history of surgery ，within 1 year of diagnosis ，chemotherapy for the first time，use of opioids ，use of 5-HT3 reuptake inhibitors ，malnutrition and electrolyte disorders.

Objective To investigate the relation between the characteristics of CD8+T lymphocyte infiltration and the prognosis of triple-negative breast cancer patients. Methods We retrospectively analyzed the clinicopathological data of 126 patients with triple-negative breast cancer undergoing preoperative neoadjuvant chemotherapy. Immunohistochemical staining was used to analyze the relation between CD8+T lymphocyte infiltration and clinicopathological characteristics. Kaplan-Meier method was used to draw the survival curve, and Cox risk ratio regression model was used to analyze the prognostic factors affecting disease-free survival time (DFS). Results High-density CD8+Tils was associated with age < 60 years old, high pathological grade and high clinical stage (P < 0.05). The pCR rate of high-density CD8+Tils group was higher than that of the low-density group (66.7% vs. 19.8%, P=0.000). The median DFS of the high-density group was significantly longer than that of the low-density group (49 vs. 25 months, P < 0.05). Multivariate analysis showed that high pathological grade, tumor diameter > 2 cm, lymph node metastasis, vascular invasion and CD8+Tils low-density infiltration were factors for poor prognosis (P < 0.05), and CD8+Tils was an independent prognostic factor. Conclusion CD8+Tils may be an independent prognostic indicator for triple-negative breast cancer. The patients with high-density infiltration have high postoperative pCR rate, long DFS and better long-term efficacy.

Objective:To translate the Spirituality and Spiritual Care Rating Scale (SSCRS) into Chinese and test its reliability and validity.Methods:After obtaining authorization from the original author, we carried out translation, back translation and cross-cultural adaptation based on the Brislin principle, and formed the Chinese version of the SSCRS. From April to June 2019, we conducted the questionnaire survey among 189 nurses at a Class Ⅲ Grade A hospital in Shiyan by convenience sampling to evaluate the reliability and validity of the Chinese version of SSCRS.Results:The Chinese version of SSCRS had 17 items. Exploratory factor analysis extracted a total of 4 common factors, with a cumulative contribution rate of 62.83%. The Cronbach's α coefficient of the entire scale was 0.840, the split-half reliability was 0.842, and the test-retest reliability was 0.860. The scale-level content validity index of all items was 0.91, and the item-level content validity index of each item ranged from 0.81 to 1.00.Conclusions:The Chinese version of SSCRS has a good reliability and validity, which can be used as an effective tool to evaluate nurses' cognition of spirituality and spiritual care in China.
