Objective To conduct a comprehensive review of the risk factors for post-transplant pulmonary infection in kidney transplant recipients. Methods Following the methodology guidelines for systematic reviews, the research question was clearly defined. Systematic searches were conducted in both Chinese and English literature databases, with the search period ranging from the establishment of the database to May 1, 2025. Two researchers independently screened and extracted the risk factors related to post-transplant pulmonary infection in kidney transplant recipients, and the research results were qualitatively described. Results A total of 45 articles were finally included, involving 30 risk factors for post-transplant pulmonary infection in kidney transplant recipients, including five aspects as donor factors, recipient factors, disease factors, treatment factors and laboratory test result factors. Conclusions The occurrence of post-transplant pulmonary infection in kidney transplant recipients is related to donor factors, recipient factors, disease factors, treatment factors and laboratory test result factors, providing a reference for clinical prevention, screening, and intervention.

Objective To explore the relationship between serum long non-coding RNA X-inactive specific transcript(LncRNA XIST)and microRNA-122-5p(miR-122-5p)expression and the severity of brain injury and prognosis in patients with sepsis-associated encephalopathy(SAE).Methods A total of 108 SAE patients(SAE group)and 52 patients with sepsis only(non-SAE group)admitted to the Ankang Hospital of Tradi-tional Chinese Medicine from January 2019 to December 2023 were selected as the study subjects.According to the degree of brain injury,the SAE patients were categorized into mild brain injury group[Glasgow Coma Scale(GCS)score 13-14,27 cases],moderate brain injury group(GCS score 9-12,36 cases),and severe brain injury group(GCS score 3-8,45 cases).Based on the 28-day prognosis,they were divided into death group(51 cases)and survival group(57 cases).Serum LncRNA XIST and miR-122-5p expression levels were measured using real-time quantitative PCR.The binding site of LncRNA XIST and miR-122-5p was predicted using the StarBase database,and Pearson correlation analysis was performed to evaluate the relationship be-tween serum LncRNA XIST and miR-122-5p expression in SAE patients.Multivariate unconditional Logistic regression was used to determine the association between serum LncRNA XIST,miR-122-5p expression,and prognosis in SAE patients.Receiver operating characteristic curves were used to assess the predictive efficacy of LncRNA XIST and miR-122-5p expression for SAE prognosis.Results Compared with non-SAE group,se-rum LncRNA XIST expression was increased and miR-122-5p expression was decreased in SAE group,with statistical significance(P＜0.05).There were binding sites between LncRNA XIST and miR-122-5p,and the expression of LncRNA XIST in serum of SAE patients was negatively correlated with that of miR-122-5p(P＜0.05).Serum LncRNA XIST expression in mild brain injury group,middle brain injury group and severe brain injury group was increased successively,while miR-122-5p expression was decreased successively,with statistical significance(P＜0.05).The 28-day mortality rate of SAE patients after admission was 47.22％(51/108).Compared with the survival group,the expression of serum LncRNA XIST was higher in the death group,and the expression of miR-122-5p was lower,with statistical significance(P＜0.05).High sequential organ failure assessment(SOFA)score and high expression of LncRNA XIST were independent risk factors for death in SAE patients,while high GCS scores and high miR-122-5p expression of were independent protec-tive factors(P＜0.05).The combined expression of serum LncRNA XIST and miR-122-5p predicted the death of SAE patients with greater area under the curve than that of serum LncRNA XIST and miR-122-5p a-lone(P＜0.05).Conclusion Elevated serum LncRNA XIST and decreased miR-122-5p expression levels are associated with the severity of brain injury and poor prognosis in SAE patients.The combined detection of Ln-cRNA XIST and miR-122-5p has a high predictive value for SAE prognosis.

BACKGROUND:Currently,research both domestically and internationally on patellofemoral pain syndrome has explored the kinematics and dynamics during daily activities such as stair ascent and descent,and walking. However,there is a lack of studies examining the lower limb biomechanical characteristics of young female patients with patellofemoral pain syndrome in different squatting conditions.OBJECTIVE:To investigate the lower limb biomechanical characteristics among young female patients with patellofemoral pain syndrome in different functional states of the subtalar joint,providing theoretical support for the clinical treatment of various types of patellofemoral pain syndrome.METHODS:A total of 33 participants were included in this study. There were 10 subjects in the healthy control group (group C). The other 27 subjects with patellofemoral pain syndrome were divided into two groups according to the foot posture index:14 subjects in the normal subtalar joint group (group A,foot posture index 0-6 points) and 13 subjects in the abnormal subtalar joint group (group B,foot posture index 7-12 points). The biomechanical indices of thesubjects in each group were collected and compared when they walked on stairs at normal speed. The kinematic indices included the three-dimensional joint angles of the hip and knee and the sagittal plane joint angles of the ankle at the initial contact moment and the moment of maximum knee flexion angle during the stance period. The dynamic indices included the three-dimensional joint torques of the hip and knee and the sagittal plane joint torques of the ankle at the moment of maximum knee flexion angle during the stance period. The surface electromyography indices included the root mean square amplitudes of the vastus medialis,vastus lateralis,rectus femoris,semitendinosus and semimembranosus,biceps femoris,and gluteus medius in the pre-activation stage and the buffering stage.RESULTS AND CONCLUSION:(1) At the initial ground contact moment,group A exhibited a greater knee flexion angle (P<0.05),greater hip external rotation angle (P<0.01),and smaller knee external rotation angle (P<0.01) compared to group B. Compared to group C,group A showed a greater knee flexion angle and smaller hip flexion angle (both P<0.01). Group B demonstrated a greater knee external rotation angle and smaller hip external rotation angle and hip flexion angle (all P<0.01) compared to group C. (2) At the moment of maximum knee flexion,group A had a smaller knee valgus angle (P<0.05),smaller knee external rotation angle (P<0.05),and greater knee flexion angle (P<0.01) compared to group B. Compared to group C,group A showed a smaller knee valgus angle (P<0.05),smaller hip flexion angle (P<0.01),and smaller hip external rotation angle (P<0.05). Group B had a smaller knee flexion angle,hip flexion angle,hip external rotation angle,and greater knee external rotation angle (all P<0.01) compared to group C. Additionally,group A exhibited a greater hip internal rotation moment (P<0.05) and plantarflexion moment (P<0.01) compared to group C. (3) At normal speed during the staircase buffering phase,group C showed higher activation levels than group A in the vastus lateralis (P<0.05),vastus medialis (P<0.01),gluteus medius (P<0.01),and biceps femoris (P<0.05). Group C also had higher activation levels than group B in the vastus medialis (P<0.01),gluteus medius (P<0.01),and biceps femoris (P<0.05). Additionally,group A showed higher activation in the semitendinosus and semimembranosus muscles compared to group B (P<0.05). (4) These findings indicate that young female patients with patellofemoral pain syndrome have stiffer hip and knee joint buffering while descending stairs,potentially compensated by the ankle joint. Low muscle activation levels contribute to patellofemoral pain,with those having normal subtalar joints but experiencing pain showing the lowest and most abnormal activation. ③ Abnormal biomechanics in the normal subtalar joint group are mainly due to insufficient hip and knee flexion. Abnormal biomechanics in the abnormal subtalar joint group are mainly due to excessive subtalar joint pronation.

Objective To explore the circRNA expression level in the urine of patients with lupus nephritis(LN),to construct a diagnostic model for LN,and to evaluate and verify its diagnostic efficacy.Methods A total of 120 patients with LN admitted from January 2022 to January 2024 were selected as the observation group and divided into the training group(n=84)and the validation group(n=36)at a ratio of 7:3.Another 100 healthy individuals who underwent physical examination were selected as the control group.The expression levels of circRNA-0001445,circRNA-002059,hsa-circ-0007385 and hsa-circ-0000006 in urine specimens of patients in the training group and the control group were detected by gene sequencing.Multivariate Logistic regression analysis was used to construct a diagnostic model for LN based on the urinary circRNA expression level.The diagnostic value of individual indicators and combined predictive models were evaluated by receiver operating characteristic(ROC)curve analysis,and then the predictive efficacy of the model was verified by the validation group.Results The expression levels of circRNA-0001445,circRNA-002059,hsa-circ-0007385 and hsa-circ-0000006 in the urine of patients in the training group were all higher than those of the control group(P<0.01).Multivariate Logistic regression analysis found that The expression levels of circRNA-0001445(OR=1.094),circRNA-002059(OR=1.040),hsa-circ-0007385(OR=1.033),and hsa-circ-0000006(OR=1.130)in theurine were independent factor for the diagnosis of LN(P<0.01).ROC curve analysis showed that the areas under the curve of combined model constructed based on the circRNA expression level in the urine were 0.985 and 0.911 in the training group and the validation group,respectively,with sensitivities of 95.00%and 91.67%,and specificities of 99.00%and 89.00%,all of which were higher than the diagnostic efficacy of a single urinary circRNA expression level.Conclusion The diagnostic model of LN constructed based on the expression level of circRNA in the urine has a high diagnostic efficacy,which has been confirmed by internal tests and may provide strong support for clinicians in the early diagnosis of LN.

OBJECTIVE To compare the efficacy of Eustachian tube pressure nebulization and insuffiation system and conventional drugs on acute otitis media of effusion in adults. METHODS Sixty ears of acute otitis media of effusion in our hospital were selected as the research objects. All patients were divided into two groups according to the treatment,which received drug therapy alone and received drug therapy and nebulizer therapy. The course lasted for 7 days. ETS,ETDQ-7,related hearing tests(acoustic immitance and pure tone threshold),and the therapeutic effect were compared among the three groups. RESULTS In drug therapy alone group,6 ears were cured,10 ears were improved,and the total effective rate was 53.3％. In drug therapy and nebulizer therapy group,17 ears were cured,9 ears were improved,and the total effective rate was 86.7％. There were no complications or adverse reactions in all patients. CONCLUSION The effective rate of the patients treated with Eustachian tube pressure nebulization and insuffiation system combined drug therapy was significantly higher than that of drug therapy alone. On the basis of conventional drug therapy combined with eustachian tube pressure nebulization and insuffiation system might can be a new effective choice for acute otitis media of effusion in adults.

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 explore the mediating effect of self-management efficacy between social support and self-management behavior in cancer patients treated with proton-heavy ions.Methods:From April 2020 to April 2021, convenience sampling was used to select 674 cancer patients in Shanghai Proton and Heavy Ion Center as the research subject. The patients were investigated with the General Information Questionnaire, Chronic Disease Self-Management Study Measures (CDSMS) , Chinese-version Strategies Used by People to Promote Health (C-SUPPH) , and Medical Outcome Study Social Support Survey (MOS-SSS) . Statistical analysis was performed using SPSS 24.0 and AMOS 24.0 software. Pearson correlation was used to calculate the correlation between variables, and a structural equation model was constructed to test the relationship between variables. A total of 674 questionnaires were distributed, 610 valid questionnaires were recovered, and the valid recovery rate was 90.5% (610/674) .Results:The total scores of self-management behavior, self-management efficacy, and social support in 610 cancer patients treated with proton heavy ions were (18.38±7.64) , (94.30±22.72) and (73.97±13.94) , respectively. Pearson correlation analysis showed that except for the dimension of life support with dimension of exercise, all the other dimension scores and the total score of patients' social support were positively correlated with all the dimension scores and the total score of self-management behaviors ( P<0.05) ; the dimension scores and the total score of patients' social support were positively correlated with the dimension scores and the total score of self-management efficacy ( P<0.05) ; the dimension scores and the total score of patients' self-management efficacy were positively correlated with the dimension scores and the total score of self-management behavior ( P<0.05) . Self-management efficacy had a partial mediating effect between social support and medical staff communication behavior, with an effect value of 23.4% ( P<0.05) . Conclusions:Cancer patients treated with proton-heavy ions have poor levels of self-management behavior. Nurses can improve the patients' self-efficacy and enhance the impact of social support on the patients' self-management behavior, so as to promote the precise realization and timely completion of proton heavy ion therapy.
