Objective:To explore the classification and influencing factors of family resilience and post-traumatic growth in patients with spinal tumor.Methods:A cross-sectional investigation was conducted among 219 inpatients with spinal tumor admitted from July 2021 to July 2022. The General Demographic Information questionnaire, Chinese-Family Resilience Assessment Scale, Posttraumatic Growth Inventory, Family Crisis-Oriented Personal Evaluation Scales (F-COPES), and Social Support Rating Scale (SSRS) were used in the study. The ordinal and multivariate logistic regression analyses was applied to identify the factors associated with the classification of family resilience and post-traumatic growth.Results:Of the 219 patients, there were 62 cases of primary spinal tumors (28.3%). According to the results of latent profile analysis, the respondents were classified into three categories by family resilience and post-traumatic growth, namely family difficulty-resistant type ( n=38, 17.4%), general resilience-struggle type ( n=99, 45.2%) and family adaptation-growth type ( n=82, 37.4%). There were significant differences in occupational status, commitment to housework, family atmosphere( χ2=10.75, P=0.025; χ2=6.95, P=0.031; χ2=11.37, P=0.017), and total score of F-COPES and SSRS ( F=25.95, P<0.001; F=19.06, P<0.001)among three groups. Ordinal and multivariate logisitc regression analyses showed that retirement ( OR=2.928, 95% CI:1.098-7.808, P<0.05), family coping ( OR=1.113, 95% CI:1.063-1.165, P<0.05), and social support ( OR=1.226, 95% CI:1.103-1.362, P<0.05) were independently associated with family resilience and post-traumatic growth in patients with spinal tumor. Conclusion:Patients with spinal tumor have significant differences in characteristics by family resilience and post-traumatic growth. As a result, more targeted interventions should be provided for different categories of spinal tumor patients in the future.

Background In the Global Burden of Disease research, it has been found that atmospheric fine particulate matter (PM_2.5) pollution significantly harms human health. Currently, there is limited research on polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) that exhibit high toxicity effects in PM_2.5 . Objective By studying the spatiotemporal distribution and variation characteristics of PCDD/Fs in PM_2.5 in Pudong area of Shanghai, to assess the associated population health risk. Methods This study set up 28 sampling points in Pudong area. One sample of PM_2.5 was collected during winter (February 2022) and summer (July 2022) at each site, with a sampling period lasting 24 h. The concentration of PM_2.5 was measured by membrane filter method, and the content of 17 kinds of 2,3,7,8-substituted chlorinated PCDD/Fs in the samples was analyzed using isotope dilution. Seasonal variations (winter and summer) in the concentrations of PM_2.5 and PCDD/Fs were evaluated, sources of PCDD/Fs pollution were tracing by principal component analysis, and health risks to the population from respiratory exposure to PCDD/Fs were estimated by VLIER-HUMAAN model. Results The PM_2.5 concentrations in the 28 samples ranged from 10 to 126 μg·m⁻³, while the concentrations of PCDD/Fs in PM_2.5 ranged from 58 to 2625 fg·m⁻³. The concentration of PM_2.5 during winter (11-126 μg·m⁻³) was higher than that during summer (10-60 μg·m⁻³). The concentration range of PCDD/Fs in winter was from 58 to 2625 fg·m⁻³, which corresponded to a range of toxic equivalent quantity (WHO-TEQ) concentration from 2.99 to 40.97 fg·m⁻³ when taking World Health Organization's toxic equivalency factor (WHO-TEQ); the concentration range of PCDD/Fs in summer was from 72 to 446 fg·m⁻³, which corresponded to a range of WHO-TEQ concentration from 2.66 to 16.61 fg·m⁻³. This range in summer was significantly lower than that observed in winter. The results of principal component analysis revealed that waste incineration was the primary source of PCDD/Fs in winter PM_2.5 in the area, whereas traffic emissions emerged as the main source in summer. The assessment of Pudong residents' respiratory exposure to PCDD/Fs in PM_2.5 showed significantly higher exposure of children in summer and winter than that of adults, indicating higher susceptibility of children to air pollutants. Both the hazard ratios (HR) for children and adults were below 1, while the cancer risks (CR) ranged from 8.41×10⁻⁸ to 2.35×10⁻⁶. Notably, during winter, the CR at 4 locations slightly exceeds 1×10⁻⁶, indicating a potential carcinogenic risk. Conclusion The overall pollution level of PCDD/Fs in PM_2.5 in Pudong area is relatively low, but it shows clear seasonal patterns. Waste incineration and traffic are the main sources of PCDD/Fs in PM_2.5 in the area. Although the cancer risk of exposure to PCDD/Fs in PM_2.5 for children or adults is relatively low, there is a certain risk at some locations in winter, necessitating additional monitoring and control.

Objective:To summarize the clinical characteristics and prognosis of severe infant botulism and evaluate the therapeutic effect of botulinum antitoxin in the pediatric intensive care unit (PICU).Methods:The clinical data of 8 cases diagnosed with infantile botulism were retrospectively analyzed in the PICU of Beijing Children′s Hospital from October 2019 to August 2023. Data of basic demographic information, clinical manifestations, laboratory tests, treatment and prognosis of each child were collected and analyzed using descriptive statistical methods.Results:Eight laboratory-confirmed cases of infant botulism were included in this study, all of which were male infants with an age of 6.0 (3.3,6.8) months. Three of the children were from Inner Mongolia Autonomous Region, 2 of them were from Hebei, and the other 3 were from Beijing, Shandong and Xinjiang Uyghur Autonomous Region, respectively. All the patients were previously healthy. In 4 of these cases, the possible cause was the ingestion of either honey and its products or sealed pickled food by the mother or child before the onset of the disease. The first symptom was poor milk intake (4 cases), followed by shallow shortness of breath (7 cases), limb weakness (7 cases) and so on. The typical signs were bilateral dilated pupils (8 cases) and decreased limb muscle strength (8 cases). The main subtype was type B (7 cases), and only 1 case was classified as type A. Six of the children were treated with antitoxin therapy for a duration of 24 (19, 49) d. Seven of them had invasive mechanical ventilation. All the patients survived upon discharge with a follow-up period of 29 d to 3 years and 8 months. Six patients had fully recovered, and 2 recently discharged patients were gradually recovering.Conclusions:For infants with suspected contact or ingestion of botulinum and presented with bilateral pupillary paralysis, muscle weakness and clear consciousness, the stool should be collected for diagnostic testing using a mouse bioassay as soon as possible. Type B was the most common type. The antitoxin treatment was effectiveness and the prognosis was well.

Objective:To investigate the clinical efficacy and safety of ferric derisomaltose injection versus iron sucrose injection in the treatment of iron deficiency anemia (IDA) .Methods:A total of 120 patients with iron deficiency anemia admitted from June 2021 to March 2023 were given intravenous iron supplementation with ferric derisomaltose to assess the efficacy and safety of hemoglobin (HGB) elevation before and after treatment. Simultaneously, the clinical effects of iron supplementation with iron sucrose were compared to those of inpatient patients during the same period.Results:Baseline values were comparable in both groups. Within 12 weeks of treatment, the elevated HGB level in the ferric derisomaltose group was higher than that of the iron sucrose group, with a statistical difference at all time points, and the proportion of HGB increased over 20 g/L in the patients treated for 4 weeks was higher (98.7%, 75.9% ). During the treatment with ferric derisomaltose and iron sucrose, the proportion of mild adverse reactions in the ferric derisomaltose group was slightly lower than that of the iron sucrose group, and neither group experienced any serious adverse reactions. The patients responded well to the infusion treatment, with no reports of pain or pigmentation at the injection site.Conclusion:The treatment of IDA patients with ferric derisomaltose has a satisfactory curative effect, with the advantages of rapidity, accuracy, and safety. Therefore, it is worthy of widespread clinical use.

Objective:This study aimed at investigating the efficacy and safety of eltrombopag in the treatment of adult primary immune thrombocytopenia (ITP) and evaluated the factors influencing its efficacy and side effects.Methods:A total of 198 patients with adult ITP who were admitted to Tianjin Medical University General Hospital between January 2018 and March 2022 were retrospectively analyzed. The efficacy of each starting dose of eltrombopag was evaluated, and adverse events were analyzed. The factors influencing efficacy were investigated, including sex, age, adult ITP type, platelet antibodies, and combined drug treatments.Results:Of the 198 patients, 70 males and 128 females with a median age of 45 years (18-88 years) were included; 130 (65.7%) had newly diagnosed adult ITP, 25 (12.6%) had persistent adult ITP, and 43 (21.7%) had chronic adult ITP. The bleeding event scores at baseline were assessed; 84.3% had scores of<4 and 15.7% had scores of ≥4. The eltrombopag response rate (initial response) at 6 weeks was 78.8% (complete response [CR]: 49.0%; CR1: 14.6%; CR2: 15.2%). The median response time to eltrombopag was 7 (7, 14) days. The initial response rates to 25, 50, and 75 mg eltrombopag were 74.1%, 85.9%, and 60.0%, respectively ( P=0.031). The initial response rate to the 50 mg dose was significantly higher than that of the 25-mg and 75-mg doses. Two patients received 100 mg as the starting dose, and their initial response was 0. Regarding dose adjustment, 70.7% of the patients remained on the starting dose, 8.6% underwent dose adjustment to 50 mg, and 6.1% underwent dose adjustment to 75 mg. Another two patients underwent dose adjustment to 100 mg. After dose adjustment, the persistent response rates were 83.6%, 85.3%, and 85.7% for the 25-, 50-, and 75-mg doses, respectively, with no significant difference. After dose adjustment, the sustained efficacy rate for the 100-mg dose (4 patients) was 100.0%. After 6 weeks of treatment with eltrombopag, the overall bleeding score of patients with ITP decreased. The number of patients with a score of ≥4 decreased to 0, the number of patients with a score of<4 decreased, and there was no significant change in the number of patients with a score of 1-2. The most common adverse event associated with eltrombopag was impaired liver function (7.7%). No thrombosis events or other adverse events were observed. ITP type and number of megakaryocytes significantly affected the initial response to eltrombopag. The initial response rates to eltrombopag for newly diagnosed adult ITP, persistent adult ITP, and chronic adult ITP were 85.3%, 56.0%, and 76.2%, respectively ( P=0.003). For megakaryocytes, the initial response rates were 61.8%, 87.1%, and 84.3% ( P=0.009) for the decreased, normal, and increased megakaryocyte groups, respectively. Conclusion:Eltrombopag, as a second-line or higher treatment for adult ITP, has a rapid onset of action and good safety. The initial response rate is significantly higher with a dose of 50 mg than with a dose of 25 mg. Patients with newly diagnosed ITP and those with normal or increased megakaryocyte numbers have a higher initial response rate to eltrombopag.

Objective:To analyze the distribution and drug resistance of pathogens of bacterial bloodstream infection in patients with hematological diseases in the Department of Hematology of Tianjin Medical University General Hospital, and to provide etiological data for clinical empirical anti-infection treatment.Methods:A retrospective analysis was conducted on the general clinical information, pathogenic bacteria and drug susceptibility test results of patients with hematological diseases diagnosed with bacterial bloodstream infection by menstrual blood culture in our center from January 2016 to December 2022.Results:Patients included 498 inpatients, with a total of 639 bacterial strains. Among the patients, 86.9% patients had malignancies, and 76.7% had agranulocytosis. Symptoms of concurrent infections, including those of the respiratory tract, oral mucosa, skin and soft tissues, and abdominal sources were observed in 68.3% patients. Gram-negative bacteria (G -) accounted for 79.0% of the isolated bacteria, and gram-positive bacteria (G +) accounted for 21.0%. The top five isolated pathogens were Klebsiella pneumoniae (22.5%), Escherichia coli (20.8%), Pseudomonas aeruginosa (15.0%), Enterococcus faecium (5.5%), and Stenotrophomonas maltophilum (5.0%). Escherichia coli exhibited a decreasing trend of resistance to quinolones, cephalosporins, and carbapenems. Klebsiella pneumoniae exhibited increasing rates of resistance to quinolones and cephalosporins between 2016 and 2018, but the rated decreased after 2019. The resistance rate to carbapenems exhibited by Pseudomonas aeruginosa was approximately 20%. Carbapenem-resistant strains of Pseudomonas aeruginosa strains were first detected in 2017, with a peak resistance rate of 35.7%, detected in 2019. A 60.0% resistance rate to methicillin was observed in methicillin-resistant coagulase-negative staphylococci (MRCNS), and one case of linezolid-resistant MRCNS was detected. Conclusions:Pathogenic bacteria of bacterial bloodstream infections were widely distributed in our center, and precautions are warranted against carbapenem resistant P. aeruginosa and Klebsiella pneumoniae.

Objective:To explore the clinical manifestations and genetic basis for a Chinese pedigree affected with atypical Charcot-Marie-Tooth disease type 1 A (CMT1A).Methods:A patient admitted to the Department of Neurology, Xijing Hospital Affiliated to Air Force Medical University in June 2022 was selected as the study subject. Clinical data of the patient was collected, and 17 family members from four generations of this pedigree were traced based on pes arcuatus and atypical clinical symptoms. Neuroultrasound and genetic testing were carried out on available family members. Whole exome sequencing and multiple ligation-dependent probe amplification assay were carried out for the proband and some of the affected members of the pedigree.Results:The proband, a 15-year-old male, had presented with paroxystic limb pain with weakness, accompanied by pes cavus and hypertrophy of gastrocnemius muscles, without stork leg sign caused by muscles atrophy in the distal lower extremities. MRI has revealed no sign of fat infiltration in the muscles of both legs. Nerve conduction examination had indicated damages of the sensory and motor nerves of the limbs, mainly with demyelinating changes. Seven members of the pedigree had pes arcuatus, including 5 presenting with paroxysmal neuropathic pain and myasthenia in the limbs, whilst 2 were without any clinical symptoms. Neurosonography of the proband, his brother, father and aunt showed thickened peripheral nerves of the extremities with unclear bundle structure. Genetic analysis revealed a large repeat encompassing exons 1 to 5 of the PMP22 gene and flanking regions (chr17: 15133768_15502298) in some of the affected members, which was predicted to be pathogenic. Conclusion:The duplication of PMP22 gene was considered to be pathogenic for this CMT1A pedigree.

Objective:To investigate the correlation between the variability of blood uric acid level and the progression of type 2 diabetic nephropathy and retinopathy.Methods:A total of 240 patients with type 2 diabetic nephropathy were selected from a cohort established in Pinggu District Hospital of Beijing in 2015 for retrospective analysis. The blood uric acid level of the patients was measured, the variability of uric acid level was calculated, and the patients were divided into group A, group B, group C and group D according to the quartile of uric acid variability, with 60 cases in each group. The subjects were followed up, and their general information, biochemical indicators, diabetic nephropathy and diabetic retinopathy were collected. According to the diabetic nephropathy and retinopathy during follow-up, the subjects were divided into progressive group and non-progressive group, so as to further clarify the correlation between the variability of blood uric acid level and the progression of diabetic nephropathy and retinopathy.Results:Up to the last follow-up date in July 2022, a total of 24 cases were lost to follow-up in group A, 27 cases in group B, 20 cases in group C, and 22 cases in group D. Finally, 36 cases were included in group A, 33 cases in group B, 40 cases in group C, and 38 cases in group D. There was no significant difference in age, gender, body mass index, systolic blood pressure, diastolic blood pressure, cholesterol, triglyceride, low density lipoprotein cholesterol, fasting blood glucose, glycated hemoglobin and serum creatinine among four groups ( P>0.05). Univariate analysis showed that the incidence of diabetic nephropathy and retinopathy progression increased with the increase of the quartile of uric acid variability in patients with type 2 diabetes (the incidences of progression in A, B, C and D groups were 16%, 49%, 63% and 79%, F = 0.95, P<0.05). Pearson correlation analysis showed that blood uric acid variability was positively correlated with the progression of diabetic nephropathy and retinopathy ( r = 0.482 and 0.501, P<0.05). Logistics regression analysis showed that with the increase of the quartile of uric acid variability, the progression risk of diabetic nephropathy ( OR = 3.521, 5.226 and 6.548; P<0.05) and retinopathy ( OR = 3.733, 4.844 and 5.872; P<0.05) in type 2 diabetes patients increased gradually. Conclusions:The variability of blood uric acid level is positively correlated with the progression of type 2 diabetic nephropathy and retinopathy. The higher the risk of progression of diabetic nephropathy and retinopathy with the increase of quartile of blood uric acid level variability, the more important it is to regularly monitor the blood uric acid level of type 2 diabetic patients.

Objective:To study the biological role and related mechanism of autophagy in acute lung injury (ALI) of hemorrhagic shock mice.Methods:According to random number table method, wild-type male C57BL/6 mice were divided into control group, ALI group, rapamycin group and 3-methyladenine (3-MA) group, with 8 mice in each group. Light chain 3 (LC3) gene knockout mice with C57BL/6 background were divided into LC3 knockout group and LC3 knockout+ALI group, with 8 mice in each group. Control group, ALI group, LC3 knockout group, LC3 knockout+ALI group were intraperitoneally injected with 2 mL/kg normal saline, rapamycin group was intraperitoneally injected with 3 mg/kg autophagy activator rapamycin, 3-MA group was intraperitoneally injected with 15 mg/kg autophagy inhibitor 3-MA, all of which were given for 3 consecutive days. 2 hours after the last administration, the hemorrhagic shock induced ALI model was established. 24 hours after modeling, the lung index was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissue and lung injury score was performed. The expressions of autophagy genes LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue were detected by Western blotting. The contents of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and malondialdehyde (MDA) in lung tissue were detected according to the steps of the kit.Results:Compared with the control group, the lung tissue structure was destroyed and exudation increased, lung index, lung injury score, the expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1, and the contents of TNF-α, IL-6 and MDA in lung tissue significantly increased in the ALI group. Compared with the ALI group, the structural damage and exudation of lung tissue were reduced in the rapamycin group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue decreased, while the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue increased [lung index: (7.56±0.39)% vs. (9.12±0.59)%, lung injury score: 3.04±0.58 vs. 9.32±2.14, TNF-α (ng/mg): 1.85±0.32 vs. 3.51±0.62, IL-6 (ng/mg): 1.61±0.32 vs. 2.52±0.44, MDA (nmol/mg): 1.03±0.16 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 1.21±0.12 vs. 0.39±0.05, Beclin-1/β-actin: 1.10±0.12 vs. 0.58±0.06, all P < 0.05], while lung tissue structure damage was aggravated and exudation was further increased in the 3-MA group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue increased, the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue decreased [lung index: (10.44±0.62)% vs. (9.12±0.59)%, lung injury score: 11.59±2.28 vs. 9.32±2.14, TNF-α (ng/mg): 4.77±0.71 vs. 3.51±0.62, IL-6 (ng/mg): 3.44±0.52 vs. 2.52±0.44, MDA (nmol/mg): 2.71±0.42 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 0.25±0.04 vs. 0.39±0.05, Beclin-1/β-actin: 0.21±0.03 vs. 0.58±0.06, all P < 0.05]. Lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue of LC3 knockout ALI mice were higher than those of wild-type ALI mice [lung index: (10.44±0.75)% vs. (9.12±0.59)%, lung injury score: 12.41±2.86 vs. 9.32±2.14, TNF-α (ng/mg): 4.85±0.72 vs. 3.51±0.62, IL-6 (ng/mg): 3.28±0.51 vs. 2.52±0.44, MDA (nmol/mg): 2.75±0.41 vs. 1.88±0.24, all P < 0.05]. Conclusion:Autophagy plays a protective role in ALI of hemorrhagic shock mice, and the related molecular mechanism is the inhibition of inflammatory response and oxidative stress response.
