Objective To study the effect of high mobility group box B1(HMGB1)gene knockout on alleviating a-cute lung injury and inhibiting toll-like receptor 4(TLR4)/nuclear factor-KB(NF-κB)pathway of sepsis mice.Methods Wild-type(WT)mice were divided into WT-Sham group and WT-model group,and HMGB1 knockout(KO)mice were divided into KO-sham group and KO-model group.Sepsis ALI model was established by cecal ligation and perforation in WT-model group and KO-model group.Sham operation was performed in WT-Sham group and KO-Sham group.24 h after modeling,the partial pressure of arterial oxygen(PaO2)was detected,oxy-genation index(OI)was calculated,pathological changes of lung tissue were detected and lung injury score was calculated,the concentrations of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1 β),interleukin-6(IL-6),reactive oxygen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD),in serum and lung tissues and the expression of HMGB1,TLR4 and nuclear NF-κB in lung tissues were detected.Results The PaO2,OI and the concentration of SOD in serum and lung tissue of WT-model group were lower than those of WT-Sham group,the lung injury scores,the concentrations of TNF-α,IL-1 β,IL-6,ROS and MDA in serum and lung tissue,and the expression levels of HMGB1,TLR4 and nuclear NF-κB in lung tissue were higher than those in WT-Sham group(P＜0.05).HMGB1 was not expressed in lung tissue of KO-model group,and the concentrations of PaO2,OI and the concentration of SOD in serum and lung tissue of KO-model group were higher than those of WT-model group,the lung injury scores,the concentrations of TNF-α,IL-1β,IL-6,ROS and MDA in serum and lung tissue,and the expression levels of TLR4 and nuclear NF-κB in lung tissue were lower than those of the WT-model group(P＜0.05).Conclusion HMGB1 gene knockout alleviates acute lung injury of sepsis mice,the re-lated molecular mechanism may be the inhibition of TLR4/NF-κB pathway mediated inflammation and oxidative stress.

Objective:To investigate the effects of bunched cognitive behavior intervention on disease fear and psychological security in patients with glioma.Methods:A total of 92 patients with glioma who underwent surgical treatment from January 2022 to June 2023 were selected.According to the order of enrollment, all subjects were divided into research group( n=44)and control group( n=48). The patients in control group received routine medical and nursing intervention, and patients the research group adopted glioma bunched cognitive behavior intervention on the basis of routine medical and nursing intervention, including 4 intervention cycles.At enrollment, 2 weeks after intervention, and 4 weeks after intervention, all subjects were evaluated by the fear of progression questionnaire-short form (FoP-Q-SF), safety questionnaire (SQ), self-rating anxiety scale (SAS) and self-rating depression scale (SDS). All the data in this study were processed by SPSS 26.0 statistical software.The scores of FoP-Q-SF, SQ, SAS and SDS before and after intervention were compared by repeated measures ANOVA between the two groups. Results:(1)The total FoP-Q-SF score, physiological health dimension scores, and social family dimension scores of the two groups showed significant interaction effects before and after intervention ( F=254.839, 52.738, 12.237, all P<0.05). Further simple effect analysis showed that after 2 and 4 weeks of intervention, the FoP-Q-SF scores of the research group (2 weeks after intervention: 33.80±4.94, 36.48±4.04; 4 weeks after intervention: 31.25±4.55, 35.94±4.47) and social family dimensions (2 weeks after intervention: 15.32±2.56 points, 17.06±2.14; 4 weeks after intervention: 14.05±2.59, 16.96±1.99) were lower than those of the control group (all P<0.05). The physiological health dimension score of the research group was lower than that of the control group after 4 weeks of intervention (4 weeks after intervention: 17.30±2.92, 19.06±2.38) ( P<0.05). After 4 weeks of intervention, the FoP-Q-SF score, physiological health dimension score, and social family dimension score of the research group were all lower than those at 2 weeks after intervention and before intervention (all P<0.05). (2)The total SQ score, interpersonal security dimension score and the determined control score of the two groups showed significant interaction effects before and after intervention( F=193.129, 54.706, 44.015, all P<0.05). Further simple effect testing showed that after 2 and 4 weeks of intervention, the total SQ score and interpersonal security score of the research group were higher than those of the control group (all P<0.05). The determined control score of the research group was higher than that of the control group after 4 weeks of intervention ( P<0.05). After 2 and 4 weeks of intervention, the total SQ score, interpersonal security score, and determination control score of the research group were higher than before intervention (all P<0.05), and the total SQ score and interpersonal security score of the research group were higher than 2 weeks after intervention (both P<0.05). (3)The SAS score and SDS score of the two groups showed significant interaction effects before and after intervention( F=237.867, 282.882, both P<0.05). Further simple effect analysis showed that after 2 and 4 weeks intervention, the SAS and SDS scores of the research group were lower than those of the control group (all P<0.05). The SAS and SDS scores of the research group were lower after 2 weeks and 4 weeks intervention than before intervention (all P<0.05). The SAS and SDS scores of the research group at 4 weeks after intervention were lower than those at 2 weeks after intervention (both P<0.05). Conclusion:Bundled cognitive behavioral intervention can improve disease fear and negative emotions in patients with glioma, and enhance psychological security.

Objective To explore the relevant relationship and specificity between the implicit and explicit loyalty of military cadets in order to provide a theoretical basis and objective indicators for a more comprehensive and objective assessment for individual loyalty.Methods E-Prime 2.0,a classic implicit association paradigm was employed to construct an implicit association loyalty test for 64 military cadets.Simultaneously,an explicit loyalty measurement was conducted using the Chinese Military Personnel Loyalty Scale.Results ① Significant implicit effect was observed in the loyalty assessment of military cadets,indicating a general tendency to perceive higher levels of personal loyalty and lower levels of loyalty to external entities.② Explicit loyalty assessment revealed that the participants had the highest loyalty score towards the Party,the Nation,and the People(4.79±0.34),followed by the loyalty score to their profession(4.38±0.53),and the relatively lower loyalty score towards the unit and leaders(4.03±0.83).Among the 3 dimensions of loyalty,the normative loyalty score ranked highest,while continuance loyalty score took lower.③ There were no correlations among the scores of loyalty to the Party,the Nation,and the People(r=-0.030,P=0.823),to the profession(r=-0.047,P=0.728),to the unit(r=0.050,P=0.710),or to the leaders(r=0.043,P=0.749).Conclusion The implicit effect in the loyalty assessment is significant in military cadets,and there is no significant correlation between explicit and implicit loyalty measurements.Thus,we cannot rely solely on explicit measurements to assess their loyalty attitudes.

Objective:To explore the effectiveness of bundled cognitive-behavior intervention in postoperative patients with glioma.Methods:From January 2022 to June 2023, convenience sampling was used to select 95 patients with glioma who underwent surgical treatment at the Neurosurgery Department of Affiliated Hospital of Jining Medical University as subjects. The patients were divided into an observation group and a control group based on the order of enrollment. The control group received routine medical nursing intervention, while the observation group received bundled cognitive-behavior intervention on the basis of control group. The scores of the Chinese-Strategies Used by People to Promote Health (C-SUPPH), Short Form Health Survey (SF-36), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) were compared between two groups of patients at different time points before and after intervention.Results:Repeated measures analysis of variance showed that there were intergroup, time, and interaction effects between the C-SUPPH, SF-36, SAS, and SDS scores of the two groups, and the differences were statistically significant (all P<0.05). At 1, 3, and 6 months after discharge, the C-SUPPH and SF-36 scores in observation group were lower than those in control group, and the differences were statistically significant (all P<0.05). At 3 and 6 months after discharge, the SAS and SDS scores of the observation group were lower than those of the control group, and the differences were statistically significant (all P<0.05) . Conclusions:Bundled cognitive-behavior intervention can increase the self-management efficacy of postoperative glioma patients, improve their quality of life, and alleviate their anxiety and depression.

The serum creatinine declined and acidosis recovered after active fluid therapy and acidosis correction. The paper summarized the characteristics of this GSD patient with renal insufficiency and the relevant literature contents, to improve the understanding of clinicians on the disease and treatment effect.

BACKGROUND: Vaccination has been shown effective in controlling the global coronavirus disease 2019 (COVID-19) pandemic and reducing severe cases. This study was to assess the flare and change in disease activity after COVID-19 vaccination in patients with stable rheumatoid arthritis (RA). METHODS: A prospective cohort of RA patients in remission or with low disease activity was divided into a vaccination group and a non-vaccination group based on their COVID-19 vaccination status. Each of them was examined every 3 to 6 months. In the vaccination group, disease activity was compared before and after vaccination. The rates of flare defined as disease activity scores based on 28-joint count (DAS28) >3.2 with ΔDAS28 ≥0.6 were compared between vaccination and non-vaccination groups. RESULTS: A total of 202 eligible RA patients were enrolled. Of these, 98 patients received no vaccine shot (non-vaccination group), and 104 patients received two doses of vaccine (vaccination group). The median time interval from pre-vaccination visit to the first immunization and from the second dose of vaccine to post-vaccination visit was 67 days and 83 days, respectively. The disease activity scores at pre-vaccination and post-vaccination visits in the vaccination group patients were similar. At enrollment, gender, RA disease course, seropositivity, and disease activity were comparable across the two groups. Flare was observed in five (4.8%) of the vaccination group patients and nine (9.2%) of the non-vaccination group patients at post-vaccination assessment ( P  = 0.221). In terms of safety, 29 (27.9%) patients experienced adverse events (AEs) after vaccination. No serious AEs occurred. CONCLUSIONS COVID-19 vaccinations had no significant effect on disease activity or risk of flare in RA patients in remission or with low disease activity. Patients with stable RA should be encouraged to receive the COVID-19 vaccination.

Objective:To analyze the distributions of ABO and RhD blood groups by analyzing the basic data of blood group detection among voluntary blood donors in Huainan in 2021, to provide data support for blood recruitment, clinical use of blood, and emergency guarantee of rare groups of blood.Methods:ABO and RhD blood groups of 24 484 voluntary blood donors eligible for blood donation in 2021 were detected using the Metis150-8 automatic blood group analyzer, manual saline method, antihuman globulin method, and manual polybrene test. The blood group results were statistically analyzed.Results:Among 24 484 voluntary blood donors in Huainan in 2021, A blood group accounted for the highest proportion (7 463 cases, 30.48%), followed by O blood group (7 444 cases, 30.40%) and B blood group (7 056 cases, 28.82%), and the last was AB blood group (2 521 cases, 10.30%). A total of 143 cases of RhD-negative blood were detected, and the negative frequency of RhD was 0.58% (143/24 484). Among the RhD-negative blood samples, 43 cases of type A, 41 cases of type B, 46 cases of type O, and 13 cases of type AB were RhD-negative, accounting for 30.07%, 28.67%, 32.17%, and 9.09%, respectively. There was no statistical difference in the detection rate of Rh-negative blood among different ABO blood groups in Huainan ( χ2 = 0.36, P = 0.948). The ABO blood group distribution of voluntary blood donors in Huainan in 2021 was not identical to those of voluntary blood donors in Guangzhou, Yueyang, Xinjiang Bozhou, Zhangzhou, and Liuzhou. The proportion of type A blood donors in Yueyang was higher than those in other regions. The proportions of type B blood donors in Huainan, Xinjiang Bozhou, and Zhangzhou were higher than those in other regions. The proportion of type O blood donors in Liuzhou was higher than those in other regions. The proportions of type AB blood donors in Huainan and Xinjiang Bozhou were higher than those in other regions. Conclusion:The distributions of ABO and RhD blood groups among voluntary blood donors in Huainan region have certain regional characteristics. Central blood banks and medical institutions should reasonably store and supply blood according to the blood collection from voluntary blood donations and the needs of clinical transfusion, to prevent the occurrence of situations such as blood expiration and waste.

Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboo-feeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism.

Objective: To explore the level of secreted phosphoprotein 24(SPP24) and its association with cardiac valve calcification(CVC), cardiovascular events(CVE) in patients with hemodialysis patients. Methods: Eighty-eight maintenance hemodialysis patients were enrolled in the study. All patients were assessed for cardiac valve calcification by echocardiography. According to the results of echocardiography, patients were divided into two groups: cardiac valve calcification group and the group without cardiac valve calcification. The levels of SPP24 were measured by enzyme-linked immunosorbent assay. Serum SPP24 levels were compared between CVC group and the group without cardiac valve calcification. Binary logistic regression was used to evaluate the association between SPP24 and cardiac valve calcification. The factors for calcification of the mitral and aortic valves were explored. The cases were followed up and cardiovascular events were recorded. COX regression model was used to analyze the factors for cardiovascular events. Results: There were 47 patients in CVC group, the levels of SPP24 in CVC group were lower than those in the group without cardiac valve calcification(P=0.040). Twenty-two patients had calcification of the mitral and aortic valves. Logistic regression analysis showed that older age(OR=1.055), hyperphosphatemia(OR=8.234) were risk factors for CVC, higher SPP24(OR=0.997) was a protective factor. Older age(OR=1.086) and hyperphosphatemia(OR=7.393) were risk factors for calcification of the mitral and aortic valves, higher SPP24(OR=0.964) level was a protective factor. Patients were followed up, the follow-up intervals were from 2 to 14 months, and it was found that CVC(HR=4.156) increased the risk of cardiovascular events in hemodialysis patients, high SPP24 level(HR=0.976) reduced the risk of cardiovascular events. Calcification of the mitral and aortic valves increased the risk for cardiovascular events(HR=3.071). Conclusion The incidence of cardiac valve calcification in maintenance hemodialysis patients is as high as 53.41%. Older age and hyperphosphatemia are risk factors for CVC, while high SPP24 level is a protective factor for CVC. CVC is an independent risk factor for cardiovascular events, and high SPP24 level is a protective factor for cardiovascular events.

Objective:To investigate the frequency of metabolic syndrome (MS) in patients with psoriatic arthritis (PsA) and further analyze the correlation of MS and its components with clinical features of PsA.Methods:Data including demographics, clinical manifestations, laboratory tests, MS-associated features (height, weight, waist circumference, blood pressure, serum lipid spectrum, and so on) and history of complications (hypertension, diabetes mellitus, atherosclerosis, coronary heart disease, and cerebral vascular disease) were collected from PsA patients in our hospital from Jan 2017 to Sep 2019. The frequency of MS in PsA patients was calculated and the association between PsA clinical manifestations and MS as well as its components was investigated.Results:One hundred and sixty-two PsA patients who fulfilled the Classification Criteria for Psoriatic Arthritis (CASPAR) were recruited. Hypertension was identified in 36 (22.2%) patients, diabetes mellitus in 28(17.2%) patients, coronary heart disease in 11(6.7%) patients, and cerebral vascular disease in 7 (4.3%) patients. Based on the criteria of the International Diabetes Federation (IDF), 58(35.8%) patients were diagnosed as MS. Compared with MS-free patients, patients with MS, hypertension or diabetes mellitus were older [(54±10 vs 44±13; 56±11 vs 45±12; 54±11 vs 44±13, respectively, t=5.058 , 4.450, 5.150, P<0.01 for all], with higher disease activity [DAPSA scores 16.75(11.25, 26.7) vs 8.8(4.8, 16.4), 16.3(9.6, 27.8) vs 10.0 (5.1, 18.0), 14.4 (9, 25.7) vs 9.5 (5, 17.7), Z=4.539 , 3.046, 3.063, P<0.01]. There was a positive correlation between the sum of components of MS and DAPSA score ( r=0.27 , P<0.01), but multiple linear regression showed no correlation between each component with DAPSA score ( P>0.05) except for hypertension ( P<0.01, standard coefficient=0.334) and elevated fasting blood glucose ( P=0.023, standard coefficient=0.247). PsA patients with hypertension had higher ESR [16.5 (9.5, 34.25) mm/1 h vs 10 (5, 24.5) mm/1 h, Z=2.127, P=0.012]. CRP level was higher in patients with dyslipidemia [5.6(2.1, 17.8) mg/L vs 3.7(1.5, 6.5) mg/L, Z=2.543, P<0.01]. Prevalence of inflammatory back pain was also higher in dyslipidemia patients (41.3% vs 22.4%, χ2=5.901, P=0.016). DAPSA score was higher in dyslipidemia patients (14.1 vs9.9, P=0.031). Conclusion:MS and its components are not rare comorbidities in PsA patients. PsA patients with MS tend to be older with higher disease activity, which calls for more attention.
