OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii （CRAB） pulmonary infection. METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024. Information such as age， gender， admitting department， infection status， underlying medical conditions， mechanical ventilation time， combination anti-infective treatment regimens， and the Acute Physiology and Chronic Health Evaluation Ⅱ （APACHE-Ⅱ） score 24 h before medication was compiled. Based on the effectiveness of the treatment， patients were divided into treatment-effective group and treatment-ineffective group. Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy. RESULTS A total of 156 patients were included， and 108 patients were treated effectively， with an effective rate of 69.23%. The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time， APACHE-Ⅱ score 24 h before medication， the number of complication types， the proportion of abnormal coagulation function， anti-infective treatment course， and hospital stay before medication （P＜0.05）. The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication [OR＝2.965， 95%CI （1.284， 6.845）， P＝0.020]， mechanical 20251606） ventilation time≥10 d [OR＝3.577， 95%CI （1.185， 10.793）， P＝0.037] and hospital stay≥14 d before medication [OR＝2.422， 95%CI （1.036， 5.654）， P＝0.041] were independent 15120420253@139.com risk factors， and anti-infective treatment course＞7 d was a protective factor [OR＝0.445， 95%CI （0.221， 0.895）， P＝0.043]. CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%. The mechanical ventilation time≥10 d， APACHE-Ⅱ score≥15 points 24 h before medication， and hospital stay≥14 d before medication may lead to treatment failure， whereas anti-infective treatment course＞7 d may be associated with treatment success.

Objective:To study and analyze the status quo and influencing factors of breast cancer patients′ concern about the upbringing of their minor children, and to provide a reference for clinical improvement of the level of breast cancer patients′ concern about parenting.Methods:A total of 247 breast cancer patients in the daytime ward of Tianjin Medical University Cancer Hospital from March to May 2023 were selected by convenience sampling. The General Information Questionnaire, Parenting Concerns Questionnaire, Parenting Sense of Competence Scale were selected for cross-sectional investigation. The multiple linear regression model was used to analyze the influencing factors of breast cancer patients′ worries about the upbringing of their minor children.Results:Finally, 240 valid questionnaires were ultimately collected. There were 12 patients with breast cancer aged 20-29 years old, 76 patients aged 30-39 years old, 117 patients aged 40-49 years old, and 35 patients aged ≥50 years old. The total score of breast cancer patients′anxiety about minor children′s rearing was (37.34 ± 2.56) points. The scores of each dimension were in order of (15.14 ± 1.02) worry about the actual impact on children, (11.15 ± 0.83) worry about the emotional impact on children, and (11.05 ± 0.71) worry about the parents of children. The total score of parenting competence (66.54 ± 11.68) points. Multiple linear regression analysis showed that parenting competence, educational level, number of underage children, per capita monthly income of families, and TNM stage (T: tumor primary lesion; N: regional lymphnode involvement; M: remote metastasis situation) affected parenting anxiety ( t values were -15.24-8.56, all P<0.05), which could explain 81.2% of the total variation in parenting anxiety level. Conclusions:Breast cancer patients′ concern about the upbringing of minor children is at a medium level, so medical staff should give relevant intervention measures to breast cancer patients with different characteristics, in order to provide reference for reducing the level of concern about the upbringing of minor children.

Objective To analyze the clinical manifestations of delayed serological transfusion reactions(DSTR)after platelet transfusion in tumor patients,and to explore the transfusion strategy.Methods Clinical data and laboratory test re-sults of patients with positive antibody screening were analyzed after platelet transfusion in our hospital from January 1,2015 to June 30,2023,and the incidence rate,clinical characteristics and transfusion strategy of patients with DSTR were ana-lyzed.Results A total of 2 553 patients with 6 057 platelet transfusions were reviewed.Eight patients developed DSTR and received a total of 21 therapeutic amounts of platelets,and 5 patients were subsequently transfused with red blood cells.Rh system antibodies were detected in 7 cases(4 anti-E,1 anti-c/E,1 anti-C and 1 anti-c)and Kell system antibodies in 1 case.Conclusion Tumor patients may also develop DSTR after platelet transfusion.It is necessary to pay close attention to the antibody situation and perform matched transfusion when transfusing blood again.

Objective To establish the drug use evaluation(DUE)standard of bivalirudin for injection,and to evaluate the use of the drug by weighted TOPSIS method,so as to provide a reference for rational use of bivalirudin.Methods Based on the package insert,clinical guidelines and consensus of experts of bivalirudin,the DUE standards were developed,and the weighted TOPSIS method was used to evaluate the rationality of the discharge medical records of Shanxi Bethune Hospital from January 1st to June 30th in 2022.Results Incorporating 108 medical records involving the use of bivalirudin for injection,88 cases(81.48％)exhibited a high degree of adherence(Ci≥0.8)between the prescribed drug regimens and the optimal recommendations,which is considered reasonable.Additionally,19 cases(17.59％)fell within the range of 0.6＜Ci＜0.8,indicating a generally reasonable adherence.Only one case(0.93％)had a Ci＜0.6,suggesting an unreasonable level of adherence.The irrational situations about various evaluation indicators in the DUE were mainly manifested in the inappropriate dosages of administration(12.04％),inappropriate disposal of adverse reactions(11.11％),using medicine with contraindications(3.70％),using medicine without indication(1.85％),inappropriate monitoring of adverse reactions(0.93％),etc.Conclusion The established DUE standards for bivalirudin are intuitive and comprehensive,and the evaluation results show that there are some unreasonable situations in the use of bivalirudin in the hospital,and it is necessary to standardize the use of bivalirudin in terms of dosages,disposal of adverse reactions,indication and contraindication.

Objective:To understand the dilemma of active management in young and middle-aged postoperative patients with lumbar disc herniation, in order to provide reference for the formulation of active intervention program of self-health management meeting the needs of patients.Methods:Using the phenomenological research method, a total of 16 middle-aged and young patients with lumbar disc herniation were selected for semi-structured in-depth interviews, and the themes were analyzed and extracted by Colaizzi 7-step analysis method.Results:Three themes and nine sub-themes were extracted namely, inadequate disease response capacity and response resources (lack of disease symptom management capacity, limited access to disease management information, difficult use of disease management information, difficulty in maintaining positive self-management for a long time (forced to stop behavior change due to stress, lack of motivation to achieve good behavior change, doubts about the effectiveness of self-management) and multi-dimensional negative emotions (contrast between maintaining independence and dependence on others, fear of being misunderstood, fear of relapse) .Conclusions:Medical staff should provide comprehensive health information services for young and middle-aged postoperative patients with lumbar disc herniation, improve the out-of-hospital follow-up mechanism with the help of information technology, further improve family and social support strategies, reduce the difficulties faced in the process of active management and achieve long-term active disease management.

Objective:To analyze the phenotype and genotype of congenital myasthenic syndrome type 10 (CMS10) caused by DOK7 gene mutation, and to conduct a literature review and summary of this disease. Methods:A retrospective analysis of the clinical characteristics and genetic test results of a patient with CMS10 in Affiliated Nanjing Brain Hospital, Nanjing Medical University in January 2020 was conducted. Whole exon sequencing was applied to high-throughput screen the pathogenic gene in this patient. After finding candidate variants, pathogenic classification was done according to the American College of Medical Genetics and Genomics and the Association for Molecular Pathology guideline. Sanger sequencing was applied to verify the mutation. Then all patients with DOK7 gene mutations were summarized by searching the literatures through PubMed, CNKI and Wanfang database. Results:The patient was a 51-year-old man who clinically presented with fluctuating quadriparesis and respiratory distress. He was diagnosed as CMS10 with compound mutations in DOK7 (c.1296_1311del16/c.332-1G>A) by clinical information and whole exon and Sanger sequencing. And c.332-1G>A was found to be a novel mutation. Literature review showed that patients with CMS10 with DOK7 gene mutations presented dominant weakness in proximal limbs and axial muscles. Patients with CMS10 would show periodic exacerbation in disease duration with slow progression. Among 71 mutations, frameshift mutation was the most frequent type (38.0%, 27/71), followed by missense mutation (32.4%, 23/71). Exon 7 (35.2%, 25/71) and exon 4 (26.8%, 19/71) were the hotspot regions. c.1124_1127dupTGCC was the most frequent mutation (43.2%, 140/324). The age of onset in patients with homozygous c.1124_1127dupTGCC was older than that in patients with compound heterozygous c.1124_1127dupTGCC [7.5(3.6, 19.8) years vs 1.3(0, 3.8) years, U=350.000, P<0.001]. Conclusions:CMS10 is a slowly progressive autosomal recessive genetic disease characterized by fluctuating muscle weakness, with muscle weakness distribution similar to limb-girdle muscular dystrophy. Frameshift mutation is the most common type in DOK7 gene associated CMS10. c.1124_1127dupTGCC in C-terminal is the most frequent mutation. Early identification of DOK7 gene associated CMS10 is crucial for the treatment and prognosis of this disease.

Objective:To investigate the effect of mindfulness-based cognitive therapy (MBCT) on mindfulness attention awareness, experiential avoidance, and cognitive fusion in individuals with general anxiety disorder(GAD).Methods:A total of 53 patients aged 18-60 years who met the GAD diagnostic criteria of DSM-5 were selected from the Seventh People's Hospital of Hangzhou from May 2021 to September 2022.After receiving routine treatment, patients were randomly assigned to two groups: MBCT group( n=26) for an 8-week mindfulness cognitive therapy and health education group( n=27) for an 8-week health education program. Participants were evaluated using the generalized anxiety disorder scale(GAD-7), acceptance and action questionnaire-2nd edition(AAQ-Ⅱ), cognitive fusion questionnaire(CFQ), and mindful attention awareness scale (MAAS) before and after the intervention.Data were analyzed using SPSS 26.0 software, with the chi-square test, independent sample t-test, and paired sample t-test. Results:(1)There was no significant difference in MAAS score between the two groups before the intervention (42.63±10.18, 47.67±9.52, t=-1.55, P=0.13). However, after the intervention, the MAAS score in MBCT group was significantly higher than that in the health education group(54.42±9.87, 47.83±7.59, t=-2.27, P=0.03). (2) No significant difference was observed in CFQ score between the two groups before the intervention (57.11±15.97, 53.50±12.01, t=-0.77, P=0.45). However, after the intervention, the CFQ score in the MBCT group was significantly lower than that in the health education group(38.32±10.31, 47.11±10.66, t=-2.51, P<0.01). (3) There was no significant difference in AAQ-Ⅱ scores between the two groups before the intervention(33.79±7.90, 30.00±7.23, t=1.52, P=0.14). After the intervention, the AAQ-Ⅱ score in the MBCT group was significantly lower than that in the health education group(21.89±8.69, 30.22±8.68, t=-3.51, P<0.01) . Conclusion:MBCT has a positive effect on enhancing mindfulness attention awareness, reducing cognitive fusion, and mitigating experiential avoidance in GAD patients.

Objective:To explore the clinical characteristics of paroxysmal kinesigenic dyskinesia (PKD) secondary to pseudohypoparathyroidism (PHP), so as to improve the clinicians′ understanding of the disease.Methods:The clinical data of 2 cases of PKD secondary to PHP in Beijing Tiantan Hospital, Capital Medical University from June 2022 to October 2022 were summarized, and the related literature was reviewed to analyze the pathogenesis, clinical manifestations, laboratory examination and imaging characteristics of the disease, as well as its treatment and prognosis.Results:Ten cases of PKD secondary to PHP were previously reported. A total of 12 cases (including these 2 cases) were included in the study, of which 7 were males (7/12) and 5 were females (5/12). The onset age was 8-23 years. The clinical manifestations of the disease included paroxysmal limb torsion, limb stiffness, limb tremor, throwing movements, and dance like movements. There were 3 cases (3/12) who had seizure at the same time. Ten cases (10/12) were induced by exercise, while 2 cases (2/12) were not mentioned the inducing factor. Eleven cases (11/12) with paroxysmal symptoms lasting less than 2 minutes can be relieved automatically. Only 1 case had a family history. Laboratory examination of all patients showed low calcium, high phosphorus and significant elevation of parathyroid hormone. The head CT scans of 10 cases (10/12) showed multiple intracranial calcifications. There were 9 cases (9/12) alone received the supplementation of calcium and active vitamin D, while 3 cases (3/12) were additionally treated with antiepileptic drugs. All cases had good prognosis.Conclusions:PHP is a rare cause of secondary PKD. A small number of patients can have seizures at the same time. Most patients have a good prognosis after receiving calcium and active vitamin D supplementation.

【Objective】 To evaluate and analyze the impact of COVID-19 epidemic on inventory of red blood cells (RBCs)in local and municipal blood stations in China, and to provide reference for the management of public health emergencies. 【Methods】 Relevant data from 2018 to 2021 were collected, and the differences in the volume of qualified RBCs, the usage efficiency of inventory RBCs, the average daily distribution of RBCs,the blood distribution rate of RBCs prepared by 400 mL whole blood, the difference in the average storage days of RBCs at the time of distribution, the average daily inventory of RBCs and the time of the average daily inventory of RBCs to maintain the distribution in 24 local and municipal blood stations in China during the COVID-19 epidemic and non-epidemic periods were retrospectively analyzed. 【Results】 Compared with non-epidemic periods, the volume of qualified RBCs [(117 525.979 ±52 203.175)U] and the average daily distribution of RBCs [( 156. 468 ± 70. 186) U ] increased significantly, but the usage efficiency of inventory RBCs decreased(97.24%±0.51%) significantly (P<0.05).There was no significant difference in the blood distribution rate of RBCs prepared by 400 mL whole blood(73.88%±20.30%), the average storage days of RBCs distribution(13.040 ±3.486), the average daily stock quantity of RBCs[(2 280.542 ±1 446.538) U ] and the time of the average daily inventory of RBCs to maintain the distribution[(15.062 ±7.453) d] (P>0.5). 【Conclusion】 During the COVID-19 epidemic, the inventory management of RBCs operated well, the overall inventory remained relatively stable, the stock composition and storage period showed no significant change.

【Objective】 To evaluate the detection and distribution characteristics of anti-P1 in tumor patients, so as to aid in blood screening and transfusion safety. 【Methods】 The clinical data of 112 658 tumor patients who underwent blood preparation and transfusion in our hospital from January 2014 to December 2021 were retrospectively analyzed, and column agglutination technique was used to perform transfusion compatibility test. 【Results】 A total of 1 079 (0.96%, 1 079/112 658) cases were detected with unexpected antibodies, of which 71 (6.58%, 71/1 079) were identified as anti-P1. In anti-P1 cases, 59.15% (42/71) were males; 60.56% had no pregnancy history (P<0.01); 29.58% (21/71), 52.11%(37/71), 12.68%(9/71) and 5.63%(4/71) of anti-P1 patients were with type A, B, O and AB, respectively. 57 cases of anti-P1 patients (80.28%) had difficulty in ABO blood group identification. The incidence of interfering in patients with type B was higher than that of other blood types (P<0.05), as the frequency of w+ in reverse blood typing was higher than other reactive patterns (P<0.05). The incidence of gastric tumor and brain space-occupying lesion in patients with anti-P1 was higher than that in patients with other alloantibodies, while the incidence of gynecological tumors was lower (P<0.05). 【Conclusion】 Anti-P1 affects the ABO blood group identification of tumor patients, and most of them had difficulty in ABO blood group identification. Compared with patients with other alloantibodies, patients with anti-P1 are more likely to be male and suffer from gastric and brain tumors, but less likely from gynecological tumors.
