Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Objective:To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China.Methods:A multicenter retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results:A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality ( OR=1.04, 1.09, 0.67, 95% CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions:Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.

Objective To investigate the application effect of a bedside ultrasound-guided intestinal cleaning program in patients with severe acute pancreatitis.Methods A total of 51 patients with severe acute pancreatitis admitted to the ICU of a tertiary A hospital in Shandong from March to September 2023 were selected by convenience sampling method,and they were divided into an experimental group and a control group according to random number table method.The experimental group was given the bedside ultrasound-guided intestinal cleaning program,and the control group was given the routine intestinal cleaning program.Acute gastrointestinal injury ultrasonography score,the incidence of grade Ⅲ acute gastrointestinal injury and intra-abdominal pressure were compared between the 2 groups before intervention,on the 3rd and 5th day.Results There was an interaction effect between time and group in the comparison of acute gastrointestinal injury ultrasonography scores in the 2 groups(F=7.478,P<0.001);simple effect analysis showed that acute gastrointestinal injury ultrasonography scores in the experimental group were lower than those in control group on the 3rd and 5th day,with statistically significant differences(P<0.05).The incidence of grade Ⅲ acute gastrointestinal injury in the experimental group(23%)was lower than that in the control group(60%),with statistically significant differences(P<0.05).The intra-abdominal pressure had an interaction effect between the 2 groups(F=47.128,P<0.001);simple effect analysis showed that the intra-abdominal pressure in the experimental group was lower than that in the control group on the 3rd and 5th day,with statistically significant differences(P<0.05).Conclusion The bedside ultrasound-guided intestinal cleaning program can improve acute gastrointestinal injury and reduce intra-abdominal hypertension in patients with severe acute pancreatitis.

Objective:To summarize the clinical features, electroencephalogram (EEG) and magnetoencephalogram (MEG) of patients with pure paroxysmal kinesigenic dyskinesia (PKD) and PKD with epilepsy, so as to better distinguish them and guide the treatments.Methods:The clinical data of 200 patients diagnosed with PKD in the Outpatient Department of Xuanwu Hospital, Capital Medical University from 2000 to 2023 were analyzed retrospectively. The patients were divided into 2 groups: pure PKD (174 cases) and PKD with epilepsy (26 cases) according to whether accompanied by epilepsy. The differences in clinical features, drug therapy, EEG and MEG were compared between the 2 groups.Results:The clinical features of the 2 groups were essentially similar, and the proportion of PKD dyskinesia induced by emotional stress in the pure PKD group (54/174, 31.03%) was higher than that in the PKD with epilepsy group (2/26, 7.69%; χ 2=5.010, P=0.025). In terms of pharmacological response, carbamazepine was the most commonly used medication in both groups, but patients with PKD with epilepsy may need a higher therapeutic dosages (0.2-0.4 g/d, and gradually increased to 0.8 g/d) to effectively manage both dyskinesia and seizures. Regarding the EEG and MEG, the proportion of EEG abnormalities was higher in PKD patients with epilepsy, mainly manifested as focal spikes [1/70(1.43%) vs 9/21(42.86%), χ 2=24.268, P<0.001], together with aberrant MEG discharge (4/18 vs 3/5, χ 2=1.155, P=0.282). The MEG dipoles were mainly distributed in the brain regions close to the frontal lobe and central region. Conclusions:The clinical manifestations of motor symptoms of pure PKD and PKD with epilepsy are similar, and carbamazepine remains the most effective treatment. PKD patients with epilepsy have a higher proportion of abnormal EEG, mainly manifested as focal spikes, and are more likely to show abnormal discharge of MEG, which could be used to distinguish them.

Objective To investigate the correlation between neuropeptide S receptor(NPSR)single nucleotide polymorphism(SNP)(rs323917,rs323920,rs323922,rs2530547,rs324957)and primary insomnia(PI).Methods A total of 157 patients diagnosed with PI in the outpatient department of Center of Sleep Medicine,Gansu Provincial People's Hospital from December 2016 to May 2019 were selected as PI group,and 133 healthy physical examination subjects during the same period were selected as control group.Venous blood samples were collected and DNA,polymerase chain reaction(PCR)amplification and agarose gel electrophoresis were extracted.rs323917,rs323920,rs323922,rs2530547,rs324957 single nucleotide loci were genotypized by target site sequencing.Meanwhile,standard polysomnosis monitoring was performed to analyze the correlation between gene polymorphism and PI.Results There were no significant differences in the genotype distribution of NPSR SNP sites(rs323917,rs323920,rs323922,rs2530547)and allele frequency and rs324957 allele frequency between two groups(P＞0.05).There was significant difference in genotype distribution of rs324957(P=0.034).There was no significant difference in the frequency of different haplotypes between two groups(P＞0.05).Conclusion The expression of rs324957 SNP genotypes in NPSR may be related to PI,and AG genotype is dominant.

ObjectiveTo investigate the effect and mechanism of Yiqi Wenyang Huwei decoction （YWHD） on airway inflammation in bronchial asthma （BA） rats based on transforming growth factor-β₁ （TGF-β₁）/SMAD family member 3 （Smad3） signaling pathway. MethodSixty male SD rats were randomly divided into a normal group， a model group， a dexamethasone （DEX） group， and low-， medium-， and high-dose YWHD groups， with 10 rats in each group. The BA model was induced by intraperitoneal injection of 1 mL of ovalbumin （OVA）-aluminum hydroxide suspension for sensitization， followed by nebulization with 2% OVA. One hour before daily OVA nebulization， the control group was treated with saline， the DEX group with DEX solution at 0.2 g·L^-1， and the low-， medium-， and high-dose YWHD groups with YWHD at 1， 2， 4 g·mL^-1， respectively. General conditions and lung function were observed. Bronchoalveolar lavage fluid （BALF） and serum were collected to count inflammatory cells in BALF and measure immunoglobulin E （IgE） levels in serum and inflammatory cytokines in BALF using enzyme-linked immunosorbent assay （ELISA）. Pathological changes in lung tissues， collagen deposition， and airway mucus secretion were observed by hematoxylin-eosin （HE）， Masson， and periodic acid-Schiff （PAS） staining. TGF-β₁/Smad3-related mRNA and protein levels in lung tissues were determined by Real-time fluorescent quantitative polymerase chain translation （Real-time PCR） and Western blot analysis. ResultCompared with the normal group， the model group showed increased total airway resistance （RL） and decreased dynamic compliance （Cdyn） （P<0.05， P<0.01）， elevated serum IgE levels， increased inflammatory cell counts， and higher inflammatory cytokine levels in BALF （P<0.01）. Additionally， there was significant inflammatory cell infiltration， collagen deposition， and mucus secretion in lung tissues. The levels of TGF-β₁， α-smooth muscle actin （α-SMA）， and Smad3 phosphorylation in lung tissues were significantly increased （P<0.01）. Compared with the model group， the DEX group and high-dose YWHD group exhibited significantly reduced RL （P<0.01）， improved lung dynamic compliance （P<0.05）， and lower serum IgE levels， inflammatory cell counts， and inflammatory cytokine levels in BALF （P<0.05）. Moreover， these treatments alleviated pathological damage in lung tissues and reduced the levels of TGF-β₁， α-SMA， and Smad3 phosphorylation （P<0.01）. ConclusionYWHD reduces airway inflammation， improves pathological damage， and mitigates airway remodeling in bronchial asthma rats， possibly by downregulating TGF-β₁， α-SMA protein levels， and Smad3 phosphorylation.

At present, all countries and regions providing palliative care service regard living wills and similar documents expressing personal wishes as the legal premise for carrying out this medical service. Defining the population receiving palliative care involves not only ethics or professional skills, but also constant revisions and changes with the development of economy and civilization. Meanwhile, the concept and promotion methods of living wills have also undergone rounds of updates. The nature of hospice and palliative care is respect for individuals, and it is the product of re-understanding the nature of life in the era of technological expansion. As a social organization promoting the concept of living will and death with dignity, we earnestly and confidently expect that hospice and palliative care become a basic right enjoyed by everyone in the near future.
