Objective To analyze the main causes and risk factors of unplanned reoperation after liver transplantation. Methods The clinical data of 242 liver transplant recipients in the First Affiliated Hospital of Anhui Medical University from January 2015 to December 2024 were retrospectively analyzed. According to whether unplanned reoperation was performed during the same hospitalization after surgery, the recipients were divided into the reoperation group (n=36) and the non-reoperation group (n=206). The preoperative, intraoperative and postoperative data of the two groups, as well as donor and graft-related data, were compared to analyze the risk factors of unplanned reoperation after liver transplantation and the survival status of the two groups. Results Among the 242 liver transplant recipients, 36 underwent unplanned reoperations, with a total of 54 procedures including various laparotomies, endoscopic and interventional surgeries, among which there were 20 laparotomies, 18 endoscopic surgeries and 16 interventional surgeries. The most common cause of unplanned reoperation was biliary complications (20 times), followed by vascular complications (17 times). Compared with the non-reoperation group, the reoperation group had longer graft cold ischemia time, higher postoperative fatality rate of recipients, longer length of stay in the intensive care unit and postoperative hospital stay, and higher total hospitalization costs (all P<0.05). The incidence of unplanned reoperation was higher in recipients who underwent split liver transplantation (P<0.05). Multivariate analysis showed that intraoperative blood loss ≥1 000 mL, positive culture of graft perfusate and split liver transplantation were independent risk factors for unplanned reoperation (all P<0.05). The postoperative 7-day, 1-month, 3-month and 6-month survival rates of recipients in the reoperation group and the non-reoperation group were 100% vs. 98.1%, 88.9% vs. 94.2%, 69.4% vs. 90.8% and 66.7% vs. 90.8%, respectively, and the postoperative survival rate of recipients in the reoperation group was lower than that in the non-reoperation group (P<0.05). Conclusions The main causes of unplanned reoperation after liver transplantation are biliary complications, vascular complications, abdominal incision infection and intra-abdominal hemorrhage. Intraoperative massive blood loss, positive culture of graft perfusate and split liver transplantation are the risk factors associated with unplanned reoperation after liver transplantation.

OBJECTIVE To explore the clinical characteristics of the nontuberculous Mycobacteria pulmonary dis-ease(NTMPD)patients with previous pulmonary tuberculosis(PPTB)and analyze the clinical difference from the recurrence of pulmonary tuberculosis.METHODS By means of retrospective survey,the patients who were diag-nosed with NTMPD and recurrent pulmonary tuberculosis in Wuhan Pulmonary Hospital from Mar.2021 to Oct.2023 were recruited as the research subjects,a total of 395 patients with NTMPD were enrolled in the study and were divided into the PPTB-NTMPD group with 92 cases and the NPPTB-NTMPD group with 303 cases according to the history of PPTB.The baseline data,clinical symptoms,imaging findings,underlying diseases,pulmonary diseases,and species of nontuberculous Mycobacteria(NTM)were observed and compared.Totally 92 patients with recurrent pulmonary tuberculosis were randomly screened and assigned as the recurrent pulmonary tuberculo-sis group in a 1:1 ratio by matching the PPTB-NTMPD group with the gender and age.The major clinical charac-teristics were compared between the two groups.The 92 patients with PPTB-NTMPD were divided into the 1-10 years group with 40 cases,the 10-30 years group with 37 cases,and the more than 30 years group with 15 cases according to the interval between the initial diagnosis of pulmonary tuberculosis and the diagnosis of NTMPD.The major clinical characteristics were compared among the groups.RESULTS The age was(64.21±10.71)years old in the PPTB-NTMPD group,(60.26±11.83)years old in the NPPTB-NTMPD group(t=3.020,P=0.003).The proportion of patients with body mass index less than 18.5 kg/m2 was 59.78％in the PPTB-NTMPD group,41.25％in the NPPTB-NTMPD group(x2=6.155,P=0.013);the proportion of patients with cough was 77.17％in the PPTB-NTMPD group,65.68％in the NPPTB-NTMPD group(x2=4.313,P=0.038);the inci-dence of cavitary shadow was 50.00％in the PPTB-NTMPD group,35.31％in the NPPTB-NTMPD group(x2=6.414,P=0.011);the incidence of emphysema and pulmonary bullae was 29.35％in the PPTB-NTMPD group,12.87％in the NPPTB-NTMPD group(x2=13.766,P＜0.001);the incidence of chronic obstructive pulmonary disease(COPD)was 22.83％in the PPTB-NTMPD group,14.19％in the NPPTB-NTMPD group(x2=3.875,P=0.049);the incidence of damaged lung was 9.78％in the PPTB-NTMPD group,2.97％in the NPPTB-NT-MPD group(x2=7.530,P=0.014);there were significant differences.Mycobacterium intracellulare and Myco-bacterium abscessus were the predominant species of NTM in both the PPTB-NTMPD group and the NPPTB-NT-MPD group,there was no significant difference in the distribution of NTM species between the two groups of pa-tients.The incidence of patch shadow of the PPTB-NTMPD group was lower than that of the recurrent pulmonary tuberculosis group(P＜0.05),the incidence of bronchiectatic shadow of the PPTB-NTMPD group was higher than that of the recurrent pulmonary tuberculosis group(P＜0.05).There were significant differences in the age,incidence of pleural thickening and incidence of COPD among the patients with different time intervals between ini-tial diagnosis of pulmonary tuberculosis and the diagnosis of NTMPD in the PPTB-NTMPD group(P＜0.05).CONCLUSIONS The previous pulmonary tuberculosis mainly affect the body mass index less than 18.5 kg/m2 and the post-tuberculosis pulmonary diseases such as cough,pulmonary cavity,emphysema,pulmonary bullae,COPD and damaged lung of the NTMPD patients.The NTMPD patients with previous pulmonary tuberculosis are more likely to have bronchiectasia than the patients with recurrent tuberculosis.It is necessary for the clinicians to attach great importance.

Objective To investigate the value of serum long noncoding RNA small nucleolar RNA host gene 7(lncRNA SNHG7)and microRNA(miR)-34a-5p expression in the diagnosis and prognostic evaluation of bloodstream infection(BSI).Methods A total of 193 suspected BSI patients admitted to the emergency department of Guangxi Wuzhou Red Cross Hospital from March 2022 to March 2023 were collected as the study subjects.After diagnosis,BSI patients were included as the infection group(n=100),and non BSI patients were included as the non infection group(n=93).After 28 days of treatment,BSI patients were separated into a death group(n=32)and a survival group(n=68)based on their prognosis.The real time fluorgenic quantitative PCR(qRT-PCR)method was applied to detect the expression levels of serum lncRNA SNHG7 and miR-34a-5p.The Target Scan Human website was applied to predict the targeting relationship between miR-34a-5p and lncRNA SNHG7.Pearson method was applied to analyze the correlation between serum lncRNA SNHG7 level and miR-34a-5p level.Multivariate Logistic regression was applied to analyze the influencing factors of prognosis in patients with BSI.Receiver operating characteristic(ROC)curve was applied to analyze the prognostic value of serum lncRNA SNHG7 and miR-34a-5p.Results The serum lncRNA SNHG7 level(1.47±0.35)in the infection group was obviously higher than that in the non infection group(1.03±0.15),and the miR-34a-5p level(0.85±0.21)was obviously lower than that in the non infection group(1.02±0.13),and the differences were statistically significant(t=11.203,6.703,all P<0.05).Compared with survival group,the serum lncRNA SNHG(1.68±0.21 vs 1.37±0.19),C-reactive protein(CRP)(85.74±9.16mg/L vs 63.18±7.68mg/L),procalcitonin(PCT)levels(56.37±8.72ng/ml vs 34.69±5.54ng/ml),albumin(92.51±10.18g/L vs 65.27±7.24g/L),Acute Physiological and Chronic Health Evaluation(APACHE II)scores(28.15±5.12scores vs 16.35±4.31scores)of the death group were obviously higher,and serum miR-34a-5p level(0.67±0.14 vs 0.93±0.16)was obviously lower,the differences were statistically significant.(t=7.357～15.340,all P<0.05).LncRNA SNHG7 had a targeted binding site with miR-34a-5p,and lncRNA SNHG7 was negatively correlated with miR-34a-5p(r=-0.568,P<0.05).Serum lncRNA SNHG7 and miR-34a-5p were prognostic factors for BSI patients(all P<0.05).The area under the curve(AUC)of serum lncRNA SNHG7,miR-34a-5p,and their combined evaluation of prognosis in BSI patients was better than that of serum lncRNA SNHG7 and miR-34a-5p detected sepatately(Z=0.001,2.304,all P<0.05),with sensitivity and specificity of 78.12%and 97.06%,respectively.Conclusion The serum lncRNA SNHG7 level in BSI patients is obviously elevated,while the serum miR-34a-5p level is obviously reduced.The two are closely related to the prognosis of BSI patients,and the combination of the two has good evaluation value for the prognosis of BSI patients.

Objective:To evaluate the efficacy of 3D printing technology combined with computer navigation-assisted screw implantation in the treatment of atlantoaxial instability (AAI) complicated by vertebral artery anomalies.Methods:A retrospective case series study was conducted to analyze the clinical data of 23 patients with AAI complicated by vertebral artery anomalies who were admitted to Honghui Hospital of Xi′an Jiaotong University between January 2019 and January 2023, including 10 males and 13 females, aged 19-70 years [(51.0±13.3)years]. Vertebral artery anomalies were categorized into unilateral high-riding vertebral artery with unilateral dominance ( n=14), bilateral high-riding vertebral arteries with unilateral dominance ( n=6), and ponticulus posticus ( n=3). All the patients underwent preoperative planning using a 3D-printed model of the atlantoaxial complex with the vertebral artery, followed by posterior atlantoaxial pedicle screw fixation with computer-assisted navigation. Operative duration and intraoperative blood loss were recorded. The accuracy of pedicle screw placement was assessed at 3 days postoperatively using the Gertzbein-Robbins classification. Visual analogue scale (VAS) scores and Japanese Orthopedic Association (JOA) scores were evaluated preoperatively, at 3 days, 3 months postoperatively, and at the last follow-up. Bony fusion was assessed using cervical CT with 3D reconstruction at the last follow-up. Complications were also observed. Results:All the patients were followed up for 12-19 months [(15.1±1.9)months]. The operative duration was 125-167 minutes [(140.6±10.9)minutes] and intraoperative blood loss was 200-600 ml [(295.7±77.8)ml]. At 3 days postoperatively, all the 66 pedicle screws were safely placed, with 60 screws (91%) rated as Gertzbein-Robbins Grade 0 and 6 screws (9%) as Grade 1. At 3 days and 3 months postoperatively, and at the last follow-up, the VAS scores were (4.0±1.0)points, (2.0±0.6)points, and (1.3±0.5)points, and the JOA scores were (14.2±1.2)points, (16.0±0.8)points, and (16.6±0.5)points, both of which were not only significantly improved compared with preoperative (5.6±1.3)points and (12.8±1.5)points, but also further improved over time ( P<0.05). At the last follow-up, 22 patients (96%) achieved satisfactory atlantoaxial bony fusion. No vertebral artery injury, spinal cord or nerve injury, cerebrospinal fluid leakage, or screw loosening were observed in any patients. Conclusion:For patients with AAI complicated by vertebral artery anomalies, 3D printing combined with computer navigation-assisted navigation for atlantoaxial pedicle screw implantation offers multiple advantages, including minimal surgical trauma, high screw placement accuracy, pain relief, neurological function improvement, high fusion rate, and lowered incidence of complications.

Objective:To explore the effect of immobility on the quality of life in older adults.Methods:This cross-sectional study included 244 consecutive elderly patients aged 60 years and older who were admitted to the Department of Geriatrics at Xuanwu Hospital of Capital Medical University from May 2022 to March 2023.Among the participants, 52.5%(128/244)were male and 47.5%(116/244)were female, with a mean age of 69.2±7.4 years.All participants underwent a series of assessments, including the Short Physical Performance Battery(SPPB), grip strength measurement, gait speed evaluation, and the Timed Up and Go test(TUG).The Barthel Index was employed to assess activities of daily living, while the Medical Outcomes Study 36-Item Short Form Health Survey(SF-36)was used to evaluate quality of life.A score of SPPB ≤ 9 was used to diagnose immobility.Results:A total of 60 older adults met the criteria for immobility.Compared to the non-immobility group, the quality-of-life scores for older adults in the immobility group were significantly lower across various dimensions, including physical functioning, role-physical, bodily pain, general health, vitality, social functioning, physical component summary, and the total SF-36 score(all P<0.05).Furthermore, a positive correlation was identified between the SPPB scores and the quality-of-life scores across the dimensions of physical functioning, bodily pain, general health, vitality, social functioning, mental health, reported health transition, physical component summary, and the total SF-36 score among patients in the immobility group(all P<0.05).Additionally, older adults in the immobility group exhibited lower grip strength, slower gait speed, and longer TUG times, as well as a higher incidence of emergencies and falls over the past year(all P<0.05). Conclusions:The poorer quality of life and physical function, along with higher rates of emergencies and falls among older adults with immobility, indicate the necessity of addressing the health consequences that immobility inflicts on this population.

Uric acid is the end product of purine metabolism in the human body. In recent years, the role of uric acid in female fertility and assisted reproductive technology (ART) has gained increasing attention. Dysregulation of uric acid metabolism can lead to hyperuricemia (HUA). HUA is not only closely related to metabolic syndrome and cardiovascular diseases but may also adversely affect female fertility by influencing ovarian function and embryos development. In this review, we explored the role of uric acid in female fertility, including its association with female subfertility, infertility, adverse pregnancy outcomes and metabolic syndrome, as well as its potential impact on ART like in vitro fertilization-embryo transfer and intracytoplasmic sperm injection. Further studies are needed to clarify the threshold and clinical intervention value of uric acid levels in women of childbearing age, providing a basis for reproductive health counseling and personalized pregnancy assistance for HUA patients of childbearing age.
