[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

Objective:To systematically evaluate the psychological experience of financial toxicity in breast cancer patients.Methods:A computer search was conducted in Web of Science, PubMed, Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang, and VIP for qualitative studies on the psychological experience of financial toxicity among breast cancer patients up to April 15, 2023. The Joanna Briggs Institute's quality assessment criteria for qualitative research were used for literature quality evaluation, and an aggregative integration method was applied for data analysis.Results:Ten studies were included, from which 56 distinct themes were extracted. These themes were consolidated into 11 new categories, forming three integrated results: multidimensional negative experiences in coping with financial toxicity, needs and expectations in dealing with financial toxicity, and strategies for dealing with financial toxicity.Conclusions:Breast cancer patients face varying degrees of financial toxicity, negatively impacting their physical and mental health. Healthcare professionals should pay close attention to the characteristics and needs of patients coping with financial toxicity. Continuous assessment of their financial status and implementation of comprehensive intervention strategies and measures through multiple channels and approaches are needed to help reduce the issues of financial toxicity.

Objective:To investigate the therapeutic effect and safety of low-dose dexitabine combined with DA/HA chemotherapy regimen in acute myeloid leukemia (AML) patients with moderate or poor prognosis.Methods:The clinical data of 25 initially diagnosed AML patients (non-acute promyelocytic leukemia) in Affiliated Hospital of Southwest Medical University from April 2013 to May 2020 were retrospectively analyzed. According to the National Comprehensive Cancer Network (NCCN) guideline, all patients were divided into moderate prognosis group (5 cases) and poor prognosis group (20 cases), and they were given low-dose decitabine combined with DA/HA regimen (decitabine 10 mg, day 1-10; daunorubicin 60 mg/m 2, day 1-3; homoharringtonine 2.5 mg/m 2, day 1-7; cytarabine 100-200 mg/m 2, day 1-7). The clinical efficacy and adverse reactions of both groups were observed. Results:Among 25 patients, 1 patient gave up during the treatment; 14 patients received 1 cycle of treatment and the complete response (CR) rate was 71.4% (10/14); 10 patients received ≥2 cycles of treatment and the CR rate was 70.0% (7/10); the difference of CR rate in patients with different treatment cycles was not statistically significant ( χ2 = 0.01, P > 0.05). In the moderate prognosis group, 4 cases achieved CR and 1 case had no response (NR), the CR rate was 80.0% (4/5), and the total effective rate was 80.0% (4/5). In poor prognosis group, 13 cases achieved CR, 4 cases achieved partial response (PR), 2 cases had NR, 1 case gave up the treatment, the CR rate was 68.4% (13/20), and the total effective rate was 89.5% (17/20). There were no statistical differences in the CR rate and the total effective rate between the two groups (both P > 0.05). The adverse reactions of all patients were mild and all patients could tolerate. Conclusions:Low-dose dexitabine combined with DA/HA regimen has a high remission rate in treatment of AML patients with moderate or poor prognosis, and the adverse reactions can be tolerated.

【Objective】 To explore the safety of RhD-positive red blood cells (RBCs) immunization schedules in RhD-negative volunteers, so as to facilitate the development of domestic anti-D immunoglobulin. 【Methods】 From January 2018 to April 2020, 23 RhD negative volunteers with informed consent were enrolled and divided into initial immunization group and booster immunization group. The initial immunization included first immunization, second immunization and third immunization. Four groups, i. e. 3 cases of 20 mL, 8 of 30 mL, 6 of 40 mL, and 6 of 50 mL, were involved in initial immunization. After the initial immunization response, booster immunizations were performed every 3 months. According to the anti-D titer before each immunization, the booster immunization doses were set to 0.5, 1 and 2 mL. Whole blood samples of 5mL/ person (time) were collected 24 h and 1 week after each infusion, and the blood routine, liver, kidney and blood coagulation function and anti-D titer were detected. The differences of detection (index) values at 24 h and 1 week after the first immunization and booster immunization in each (dose) group were compared. 【Results】 No statistically significant differences were observed in hemolysis index values (all within the range of medical reference values) 24 h or 1 week after initial immunization among RhD positive RBCs of 20, 30, 40 and 50mL(P>0.05). The differences between the hemolysis index values and the basic values before the immune response (all within the range of medical reference values) after 0.5 or 1 mL booster immunizations were also not statistically different (P>0.05). However, the differences (μmol/L)between total bilirubin levels and the basic values before the immune response (1.55±1.87, 6.29±2.66) were significantly different after 2 mL booster immunization (P<0.05). 【Conclusion】 No risks affecting the safety of RhD negative volunteers was found in the immunization schedule proposed in this study.

During the COVID-19 epidemic, our national guidelines have suggested that surgical patients should wear a mask to decrease the potential transmission of COVID-19 in the operating room, as long as the condition allows. However, so far, there is no study to discuss the influence of wearing a mask on the ventilation and blood oxygenation status in patients of spontaneous breathing with supplementary oxygen through an anesthetic facemask. This is a before-after study in the same patient, and 10 healthy volunteers were recruited, by testing the arterial blood gas parameters at key time points before and after oxygen inhalation to evaluate the effects of two different supplementary oxygen methods ('disposable medical mask + anesthetic facemask' and 'anesthetic facemask only') on the oxygenation of subjects. Our data demonstrated whether wearing a disposable medical mask or not could effectively increase the oxygen supply of the subjects compared with the basic value before oxygen inhalation; however, compared with the group without mask, the arterial oxygen partial (PaO

Objective: To evaluate the diagnostic value and feasibility of narrow-band imaging in detection of recurrent nasopharyngeal carcinoma (NPC). Methods: One thousand three hundred and sixty-four NPC patients who had completed NPC treatment were enrolled. All patients were followed-up with imaging, serological examination of EB virus and nasopharyngeal endoscopy(WL and NBI mode), in which (1) both white light (WL) and NBI modes were done; (2) positive endoscopic patients were given nasopharyngeal biopsy; (3) using histologic finding as criterion standard, the sensitivity, specificity, accuracy and Yonden′s index of two modes were compared. Kappa index was used to evaluate the consistency between the two modes and pathological results respectively; (4) the positive rates of WL and NBI in patients with early recurrent (stage Ⅰ+ Ⅱ) were compared. Results: A total of 265 cases were suspected as having recurrent lesions by endoscopy in WL mode and 68 cases of them were pathologically diagnosed as having NPC; and 82 cases were suspected as having recurrent lesions by endoscopy in NBI mode and 74 cases of them were pathologically diagnosed as having NPC. The sensitivity, specificity, accuracy and Yonden′s index of WL mode were 91.89%, 0, 25.09% and -0.0811, respectively, with a kappa of -0.045; the sensitivity, specificity, accuracy and Yonden′s index of NBI mode were 100.00%, 95.94%, 97.05% and 0.9594, respectively. Conclusion NBI has higher sensitivity, specificity, early diagnosis rate and Yonden′s index than WL.

OBJECTIVETo evaluate the efficacies of different treatments for recurrent cervical lymph nodes and the factors contributing to prognosis in patients with nasopharyngeal carcinoma after radiotherapy.

METHODSClinical data of 79 patients with nasopharyngeal carcinoma after radiotherapy were retrospectively analyzed, and all cases were diagnosed as having recurrent cervical lymph nodes by pathological examination. The factors including sex, age, the interval between completion of radiotherapy and recurrence, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor in the neck were analyzed for prognosis. Kaplan-Meier curves, Log-rank test and Cox's proportional hazards regression mode were used in the statistical analysis.

RESULTSThe median recurrence time was 26 months, and the 1- , 3- and 5-year overall survival rates were 77.9%, 53.4% and 39.7%. Cox's proportional hazards regression mode analysis indicated that age, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor were significantly prognostic factors.

CONCLUSIONSNeck dissection is superior to re-radiotherapy in treatment of recurrent cervical lymph nodes in nasopharyngeal carcinoma after radiotherapy. The patients younger than 45 years old, in early rN stage and for recurrence in the center region of primary tumor have a better prognosis.
