Objective:This study implemented a pulmonary rehabilitation integrated care management model based on an Internet of things platform for patients with chronic obstructive pulmonary disease (COPD) and evaluated its effectiveness to provide evidence for clinical respiratory rehabilitation practices.Methods:A quasi-experimental design was adopted. Patients from the Department of Respiratory and Critical Care Medicine at Changsha Central Hospital Affiliated to University of South China between May and December 2023 were selected via purposive sampling. Sixty COPD patients from May to August 2023 were assigned to the control group, while 60 patients from September to December 2023 were assigned to the comprehensive management group. The control group adopted routine respiratory rehabilitation management, the comprehensive management group adopted a pulmonary rehabilitation integarted care management mode based on Internet of things platform respiratory rehabilitation. Before and after 6 months of intervention, patients were assessed for respiratory rehabilitation compliance, lung function (including the percentage of forced expiratory volume in the first second to the expected value (FEV 1% pred) and the ratio of forced expiratory volume in the first second to forced vital capacity (FEV 1/FVC), 6-minute walk test (6MWT) and COPD Assessment Test (CAT). Results:Finally, 55 cases were included in the control group and 59 cases were included in the comprehensive management group. The control group included 32 males and 23 females, aged (67.31 ± 7.14) years. The comprehensive management group included 39 males and 20 females, aged (68.15 ± 6.34) years. The respiratory rehabilitation compliance score, FEV 1% pred, FEV 1/FVC, 6MWT, and CAT score of the full management group after intervention were as follows: (26.45 ± 1.51) points, (59.21 ± 6.68)%, (78.35 ± 8.01)%, (479.63 ± 54.70) m, and (12.35 ± 4.01) points, which were all better than the control group′s (15.68 ± 1.56) points, (44.09 ± 6.31)%, (68.38 ± 6.43)%, (429.82 ± 60.50) m, and (17.03 ± 4.23) points. The difference between two groups were significant ( t values were 1.83-5.24, all P<0.05). Conclusions:The pulmonary rehabilitation integarted care management model based on Internet of things platform improves patient compliance, enhances pulmonary function, enhance their activity endurance, and improve their quality of life. It is worth promoting and using in clinical practice.

Compared to traditional suturing, lung stapling using automatic staplers offers advantages such as smaller trauma, faster wound healing, ease of operation, and lower complication rates, making it widely used in clinical practice. However, there are significant differences in bronchial tissue thickness at different anatomical locations, and the market is flooded with various types of staplers. Currently, there is a lack of recommended stapling schemes for bronchial staplers at different anatomical locations. This article reviews the development and application of automatic staplers and summarizes some types of staplers that are currently used in clinical practice, with the aim of promoting the formation of individualized stapler selection protocols for minimally invasive thoracic surgery based on the Chinese population.

Objective:To investigate the potential value of cerebral glucose metabolism characteristics in anti-leucine-rich glioma-inactivated protein 1 (LGI1) antibody-related encephalitic patients during acute phase as the clinical indicator of disease outcomes.Methods:From October 2019 to December 2023, 28 patients (18 males, 10 females; age (56.6±11.9) year) with anti-LGI1 antibody-related encephalitis diagnosed at Huashan Hospital, Fudan University were prospectively enrolled. All patients received baseline brain 18F-FDG PET imaging and were divided into different subgroups according to the prognosis (good prognosis and poor prognosis groups) and recurrence (recurrence and non-recurrence groups) after follow-up. The difference of Montreal Cognitive Assessment (MoCA) score between the two groups was compared by Mann-Whitney U test. Statistical parametric mapping (SPM) analysis was used to analyze the PET images of different groups by independent-sample t test, and the characteristics of cerebral glucose metabolism of patients with different outcomes were obtained. Results:MoCA scores between the recurrence group ( n=6) and the non-recurrence group ( n=22; 14.0(9.8, 20.5) vs 22.0(18.0, 24.0); Z=2.17, P=0.030), and between the poor prognosis group ( n=13) and the good prognosis group ( n=15; 14.0(10.0, 22.0) vs 22.0(19.8, 25.3); Z=2.47, P=0.013) were significantly different. Compared with the good prognosis group, the cerebral glucose metabolism in the poor prognosis group was decreased in the bilateral frontal lobe, lateral temporal lobe, inferior parietal lobule and cingulate gyrus, but increased in the brainstem, bilateral lentiform nucleus and bilateral paracentral lobule/postcentral gyrus (all t=1.71, all P<0.05). Compared with the non-recurrence group, the metabolism of bilateral medial frontal gyrus, anterior cingulate gyrus, bilateral insula, superior temporal gyrus and thalamus decreased in the recurrence group, while the metabolism of bilateral precentral gyrus, inferior frontal gyrus and bilateral lentiform nucleus increased (all t=1.71, all P<0.05). Conclusion:18F-FDG PET imaging reveals the differences in brain metabolism of anti-LGI1 antibody-related encephalitic patients at baseline with different outcomes (prognosis, recurrence or not), which can provide a new perspective for the clinical evaluation of the disease at baseline.

Objective To summarize the clinical characteristics of children with drug-induced hypersensitivity syndrome(DIHS)complicated with herpesvirus reactivation,and to promote the early and accurate identification,diagnosis,and treatment of DIHS in children.Methods The medication history,clinical manifestations,treatment,and prognosis of 12 children confirmed DIHS complicated with herpesvirus reactivation in Guangzhou Women and Children's Medical Center between January 2018 and March 2023 were retrospectively analyzed.The changes in hematological parameters,inflammatory indexes,and hepatic and renal function within 5 d before the eruption,5 d,and 6-10 d after eruption were compared.Results Of the 12 patients,the male-to-female ratio was 5∶1,with a median age of 27(interquartile range 20.50-34.75)months.Two or more antibiotics were used at least two to six weeks before onset,with a combination of 3 or more antibiotics in 7 children,and a combined or sequential application of 2 antibiotics in 5 children.The antibiotics included cephalosporins(n=12),semisynthetic penicillins(n=5),vancomycin(n=4)and azithromycins(n=7).All 12 patients presented fever,rashes,and multiple organ involvement.The rashes were red maculopapules in the early stage and then gradually developed into massive fusion exceeding 50%of the whole body.Among them,seven children were accompanied by facial edema,and two had purplish-red facial rashes.11 children suffered from exfoliative dermatitis in the later stage.12 children presented obviously enlarged lymph nodes.Liver involvement was the most common(100%,simple increase of transaminase in four children,cholestasis in six children,and hepatic failure in two children),and lung involvement was found in nine children.Laboratory examination showed no significant increase in leukocytes or eosinophils within 5 d before the eruption,but low levels of atypical lymphocytes.After the eruption,leukocytes,eosinophils,and atypical lymphocytes increased progressively.Inflammatory indexes of hypersensitive C-reactive protein(CRP),procalcitonin(PCT)increased dramatically before and after the eruption.All the children received intravenous immunoglobulin(IVIG)and methylprednisolone,two children were given antiviral therapy,and nine children were treated with multiple plasma exchanges.After treatment,nine children were cured,one developed immune reconstitution syndrome,and two died of hepatic failure.Conclusions Antibiotics are common allergenic drugs for DIHS in children.Its clinical manifestations include fever and rashes,accompanied by multiple organ involvement,such as the liver and lung.When leukocytes,eosinophils,and atypical lymphocytes are progressively elevated after the eruption,DIHS should be highly suspected,herpesvirus activation should be monitored,medication history should be traced,and early active immunotherapy and antiviral therapy should be conducted if necessary.

Purpose To investigate the characteristics of 18F-Florbetaben(18F-FBB)β-amyloid(Aβ)PET imaging in different brain regions of Alzheimer's disease(AD)patients with different degrees of cognitive impairment,and to explore the correlation between Aβ deposition and cognitive dysfunction.Materials and Methods A total of eighteen patients with a clinical diagnosis of probable AD from August 2022 to October 2023 were retrospectively included in Huashan Hospital.All patients had Aβ abnormal deposition in the brain as confirmed by 18F-FBB PET imaging.According to the severity of symptoms,they were divided into the AD-induced mild cognitive impairment(MCI)group(8 cases)and the dementia group(10 cases).In addition,12 healthy controls were included.First,the standardized uptake value ratio of abnormal Aβ deposition in the frontal lobe,lateral parietal lobe,lateral temporal lobe,anterior and posterior cingulate gyrus,and compound cortex was semi-quantitatively calculated and compared among the three groups based on the subjects'brain MRI and automated anatomical labeling template.The correlation between the degree of Aβ deposition in the brains of AD patients and cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)was then further analyzed.Results The standardized uptake value ratio values of Aβabnormal deposition in the frontal lobe,lateral temporal lobe,lateral parietal lobe,anterior and posterior cingulate cortex and compound cortex in the AD-induced MCI and dementia groups were significantly higher than those in the healthy controls(t=7.442-9.151,all P＜0.05).However,there was no significant difference in the standardized uptake value ratio values of Aβ abnormal deposition in the above brain regions between the MCI and dementia groups(t=0.312-0.996,all P＞0.05).In addition,there was no significant correlation between the degree of Aβ deposition in the brain and the cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)in the AD-induced MCI and dementia groups(r=-0.049-0.050,all P＞0.05).Conclusion Aβ deposition in the brains of AD-induced MCI and dementia is significantly higher than in the healthy controls.However,Aβ deposition cannot identify AD patients with different degrees of cognitive impairment,reflecting that Aβ deposition has certain limitations in assessing the severity of clinical symptoms of AD.

Objective:To explore the effect of continuous nursing on the psychology and quality of life of patients with mild traumatic brain injury.Methods:A review of 120 patients with mild traumatic brain injury who were hospitalized in the Second Affiliated Hospital of Wenzhou Medical University from January 2016 to December 2019 were selected. According to the order of admission, sample numbers were drawn from the random number list and entered into groups. There were 60 cases in the control group and the intervention group. The control group received routine general nursing, and the intervention group received continuous nursing. The Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and Quality of Life Scale (SF-36) were used to evaluate the psychology and quality of life of patients on the day of discharge and one week, one month, and three months after discharge.Results:There was no significant difference in the scores of HAMA, HAMD and SF-36 between the two groups on the day of discharge ( P>0.05). The HAMA scores at 1 week, 1 month and 3 months after the intervention of the intervention group were (18.2±8.6), (13.7±5.8) and (5.6±2.3), which were significantly lower than those of the control group (24.2±11.2), (20.4±8.2), (8.9±3.6), the differences were statistically significant ( t values were 2.32, 3.67, 4.13, P<0.05). The HAMD scores at 1 week, 1 month and 3 months after the intervention of the intervention group were (24.3±7.1), (10.9±4.2), (6.8±2.9), which were significantly lower than those of the control group (28.6±8.5), (15.3±8.3), (14.8±4.6), the differences were statistically significant ( t values were 2.11, 2.57, 7.99, P<0.05). The SF-36 scores at 1 week, 1 month and 3 months after the intervention of the intervention group were (77.2±8.9), (85.2±9.7), (87.8±12.9), which were significantly higher than those of the control group (72.3±8.2), (79.4±10.9), (81.0±11.5), the differences were statistically significant ( t values were -2.23, -2.14, -2.13, P<0.05). Conclusions:Continuing care can be extended to the patient's family, so that the health problems faced by the patient after discharge from the hospital can be effectively solved, relieve psychological pressure and improve the quality of life, and it is worthy of clinical application.
