Objective:To observe the clinical efficacy of against-lateral correction Tuina(Chinese therapeutic massage)in treating atlanto-axial joint disorder(AAJD)and imaging changes.Methods:A total of 142 patients with AAJD were recruited.They were randomly allocated to a trial group and a control group using the random number table method,with 71 participants in each group.The trial group was treated with against-lateral correction Tuina 3 times weekly.The control group was offered conventional physical traction therapy once daily.The interventions lasted 2 weeks in both groups.The two groups of participants were observed before and after treatment for their changes in the global pain scale(GPS)score,visual analog scale(VAS)score for dizziness assessment,cervical range of motion(ROM)in rotation,and the extent of atlanto-dental displacement.Results:The GPS and VAS scores dropped after treatment in both groups(P<0.05)and were lower in the trial group than in the control group after treatment and at the follow-up(P<0.05).Participants in the trial group achieved a significant increase in the cervical ROM in rotation after treatment and at the follow-up compared to the pre-treatment value(P<0.05)and surpassed the control group(P<0.05);the control group only showed an increase in the left-side rotation(P<0.05).After the intervention,neither the intra-group nor the between-group comparison revealed significant differences in the extent of atlanto-dental displacement(P>0.05),though the trial group presented an improving tendency.Conclusion:Compared to physical traction,the against-lateral correction Tuina method works more significantly in improving pain,dizziness,and ROM in AAJD patients.

Objective To analyze the correlations between the thoracic electrical impedance tomography(EIT)-derived parameters global inhomogeneity(GI),center of ventilation(COV),regional ventilation delay(RVD),and atelectasis in hospitalized patients,and to explore their effectiveness in evaluating atelectasis.Methods The clinical data of 140 hospitalized patients monitored by thoracic EIT between Sep.2024 and Jan.2025 were retrospectively analyzed.Patients were assigned to 2 groups based on chest computed tomography confirmation of atelectasis within the preceding short-term period during EIT monitoring:non-atelectasis group or atelectasis group.The algorithm software designed with MATLAB was used to acquire GI and COV.RVD was obtained through analysis with the Dr?ger EIT Data Analysis Tool 6.3 software,and patients'general data were concurrently documented.Comparative analysis of EIT-derived parameters between groups was conducted.Multivariate logistic regression analysis was employed to investigate the correlations of GI,COV,and RVD with atelectasis,while receiver operating characteristic curve analysis was performed to assess the efficacy of EIT-derived parameters in evaluating atelectasis.Results A total of 140 patients were enrolled,with 19(13.6%)cases presenting atelectasis.Compared to the non-atelectasis group,the atelectasis group demonstrated significantly higher proportions of male patients and cardiovascular disease and thoracic surgery(non-pulmonary)histories,lower body mass index(BMI),and alongside elevated GI and RVD values with reduced COV(all P＜0.05).Multivariate logistic regression analysis revealed that GI,COV,and RVD maintained independent associations with atelectasis after adjusting for age,gender,BMI,pleural effusion,and emphysema(odds ratio[OR]=1.39,95%confidence interval[CI]1.20-1.67;OR=0.85,95%CI 0.75-0.96;OR=1.22,95%CI 1.09-1.39;all P＜0.05).The area under curve(AUC)values of GI,COV,and RVD for evaluating atelectasis in hospitalized patients were 0.82,0.80,and 0.82,respectively(while RVD demonstrated a higher AUC,its clinical applicability was influenced by respiratory patterns).Conclusion Thoracic EIT-derived parameters GI and COV demonstrate significant correlations with atelectasis and may serve as valuable indicators for evaluating atelectasis in hospitalized patients.

Objective:To explore the diagnostic key points, treatment strategies, and prognosis of graft-versus-host disease (GVHD) after liver transplantation.Methods:The clinical data of 5 recipients diagnosed with GVHD after liver transplantation at the Liver Transplantation Center of the First Affiliated Hospital of Army Medical University from May 1999 to October 2024 were retrospectively analyzed. The causes, onset, diagnosis, treatment, and prognosis of GVHD after liver transplantation were summarized and analyzed. Literature was searched in CNKI, Wanfang, VIP, Chinese Medical Journal Full-text Database, PubMed, Web of Science, and Google Scholar using the Chinese keywords "移植物抗宿主病+肝移植", and the English keywords "graft versus host disease + liver transplantation". The search time ranged from January 1988 to January 2025. Inclusion criteria for the literature: (1) meeting the clinical or pathological diagnostic criteria of GVHD after liver transplantation; (2) recipient age >18 years; (3) case number ≥2. Exclusion criteria: incomplete clinical data such as incidence, mortality, and clinical manifestations of GVHD after liver transplantation. The retrieved literature was reviewed.Results:All 5 recipients were male. Among them, 4 cases underwent liver transplantation at this center. The incidence of GVHD after liver transplantation in this center was 0.46% (4/872). All 5 cases developed symptoms such as fever, rash, diarrhea, oral ulcers, and pancytopenia on the 19th (5-21) day after liver transplantation. One case had gastrointestinal bleeding. Two cases were diagnosed by skin pathological biopsy, and three cases were diagnosed based on clinical manifestations such as fever, rash, diarrhea, and bone marrow suppression. One case discontinued immunosuppressants, and four cases reduced the dosage of immunosuppressants. Four cases were treated with high-dose glucocorticoids, four with intravenous immunoglobulin (IVIG), three with ruxolitinib, and three with hematopoietic factors. All five cases received protective isolation, anti-infection, and symptomatic supportive treatment. Among the three recipients treated with ruxolitinib, body temperature returned to normal, rash gradually faded, oral ulcers gradually healed, blood cells returned to normal, and they were eventually discharged after recovery. The remaining two cases showed no symptom improvement and died of severe lung infection and multiple organ failure. Literature review A total of 34 articles were included. The incidence of GVHD after liver transplantation was 1.03% (279/27 018), and the onset time ranged from 7 to 1,865 days post-transplantation; 272 cases (97.49%) occurred within 1-8 weeks. The main clinical manifestations included fever (195 cases, 69.89%), rash (267 cases, 95.70%), diarrhea (173 cases, 62.01%), and bone marrow suppression (214 cases, 76.70%). Treatment mainly involved adjustment of immunosuppressants (201 cases, 72.04%), high-dose corticosteroids (215 cases, 77.06%), and IVIG pulse therapy (146 cases, 52.33%). In the end, 83 cases (29.75%) recovered and were discharged, while the mortality rate was 70.25% (196/279), with causes of death including infection, gastrointestinal bleeding, and multiple organ failure.Conclusions:GVHD after liver transplantation has a low incidence, high mortality, and poor prognosis. Diagnosis mainly relies on typical clinical manifestations and pathological results of tissue biopsy. Early administration of high-dose corticosteroids combined with IVIG pulse therapy, timely reduction or discontinuation of immunosuppressants, use of ruxolitinib, active infection management, and enhanced symptomatic and supportive care are effective strategies for treating GVHD after liver transplantation.

Objective To explore the beneficial effects and mechanisms of neutrophil elastase (NE) and myeloperoxidase (MPO) on lead-induced hepatic inflammation in mice. Methods The specific pathogen free male C57BL/6 mice were randomly divided into four groups： control group, lead-exposed group, NE inhibitor group, and MPO inhibitor group, with three mice in each group. The mice in lead-exposed group, NE inhibitor group, and MPO inhibitor group were intraperitoneally injected with a dose of 10 mg/kg body mass of lead acetate solution, while the mice of control group received an equal volume of 0.9% saline three times per week for four weeks. In the last seven days, mice in both inhibitor groups were intraperitoneally injected with a dose of 40 mg/kg NE inhibitor sivelestat sodium or MPO inhibitor 4-aminobenzoic acid hydrazide (4-ABAH) once per day. Mouse body weight and liver histopathological changes were observed. The mRNA expression of genes associated with inflammation, such as tumor necrosis factor-α (Tnfa), interleukin-1β (Il1b), interleukin-6 (Il6), and nucleotide-binding oligomerization domain-like receptor protein 3(Nlrp3), apoptosis-associated speck-like protein (Asc) and cysteinyl aspartate specific proteinase (Caspase1) in the mouse liver tissues was detected by real-time quantitative polymerase chain reaction. The protein expression of NLRP3, ASC, and CASPASE-1 was detected using Western blotting. Results The activities of mice in all four groups were generally normal, and there was no significant difference in body weight (P>0.05). The results of hematoxylin-eosin staining showed that the cell size of hepatocytes varied in the lead-exposed mice, with indistinct cell boundaries, indicating early inflammatory responses in liver tissues. After intervention with NE or MPO inhibitors, the early inflammatory responses improved in the liver tissues of the mice in both inhibitor groups, with a better improvement observed in MPO inhibitor group compared with the NE inhibitor group. The mRNA expression of Tnfa, Il1b, Il6, Nlrp3, Asc, and Caspase1, as well as the protein expression of ASC, and CASPASE-1 in the livers of mice in the lead-exposed group was higher compared with those in the control group (all P<0.05). Compared with the lead-exposed group, the relative mRNA expression of Tnfa, Il1b, Il6, Nlrp3 and Asc was decreased in the liver tissues of mice in the NE inhibitor group (all P<0.05), while the relative expression of mRNA of Tnfa, Il1b, Il6, Caspase1 and the protein expression of ASC and CASPASE-1 were decreased in the liver tissues of mice in the MPO inhibitor group (all P<0.05). Conclusion Lead induce hepatic inflammation in mice by activating NLRP3 inflammasome. The inhibition of NE or MPO improve the lead-induced hepatic inflammatory responses in mice by alleviating NLRP3 inflammasome activation.

Objective:To evaluate the quality of life (QoL) of Chinese chronic pancreatitis (CP) patients based on the Chinese version of the pancreatitis quality of life Instrument (PANQOLI) and explore its impact factors.Methods:404 patients with CP admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between September 2021 and January 2022 were enrolled. The Chinese version of PANQOLI was used for questionnaire survey on QoL of CP patients. Univariate analysis and multiple linear regression analysis were used to explore the impact factors for QoL of CP patients.Results:The total score of QoL of 404 Chinese CP patients was 28-94(72.47±13.61), which declined by 29.64% compared to the highest total score (103) in the Chinese version of PANQOLI. Score of physical function, role function, emotional function, and self-worth domain was 25.63±4.84, 13.86±2.78, 16.98±6.21 and 16.00±4.65, respectively. Compared to the highest scores (30, 25, 24 and 24), the scores of aforementioned four domains declined by 14.57%, 44.56%, 29.25% and 33.33%, respectively. Univariate analysis showed that sex, age, employment status, smoking, alcohol consumption, and frequency of pancreatitis recurrence were significantly associated with QoL of CP patients. Multiple linear regression analysis indicated that older age (coefficient=-0.127), unemployment status (coefficient=-0.106), smoking (coefficient=-0.176), and high frequency of pancreatitis recurrence (coefficient=-0.123) were independent factors for QoL of CP patients (all P value <0.05). Conclusions:The Chinese version of PANQOLI could be effectively applied to Chinese CP patients. Older age, unemployment, smoking, and pancreatitis attacks were risk factors for QoL of CP patients, indicating that the formulation of personalized intervention measures may help to improve QoL of CP patients.

Objective:To investigate the prevalence and risk factors of functional gastrointestinal disorders（FGIDs）among officers and sailors on a long oceangoing voyage.Methods:A total of 307 officers and sailors on a hospital ship undertaking a long oceangoing mission were selected as study subjects and surveyed by the Rome IV Diagnostic Questionnaire for Functional Gastrointestinal Disorders in Adults. The multivariate logistic regression was used to analyze risk factors of FGIDs.Results:A total of 300 valid questionnaires were collected，and the valid rate was 97.7%（300 / 307）. The total prevalence of FGIDs in officers and sailors on the long oceangoing mission was 11.00%（ n=33），among which the prevalence of unspecified functional bowel disorder was the highest（3.33%），followed by functional dyspepsia（2.00%），functional constipation（1.67%），functional diarrhea（1.33%），nausea and vomiting（1.33%），etc. According to the univariate analysis，gender，body mass index（BMI），type of work，times of undertaking oceangoing mission，location of berthing cabin，seasickness，and eating instant noodles were associated with the occurrence of FGIDs（ P<0.05）. The multivariate logistic regression analysis of the occurrence of FGIDs showed that the gender of male was a protective factor，while the decline of BMI and frequently eating mustard tuber were risk factors. Conclusion:The prevalence of FGIDs in officers and sailors on long oceangoing missions is relatively high，and the occurrence of FGIDs is related to gender，BMI，and eating mustard tuber.
