Objective:To explore the risk factors for recurrence of intussusception in children after successful ultrasound-guided saline enema reduction.Methods:The clinical and follow up data of 355 hospitalized children with intussusception at the First Affiliated Hospital of Zhengzhou University from Feb 2018 to Feb 2023 were reviewed.Patients were divided into two groups by recurrence develped and the differences were compared, Data with significant differences were incorporated into multi-factor logistic analysis.Results:The overall recurrence rate was 15.8% (56/355). By univariate variable analysis model, there were statistically significant differences between the two groups in age, previous intussusception history, vomiting, maximum diameter of concentric circles shown by ultrasound, and concurrent bowel organic diseases (lead points) (all P<0.05). In multivariate Logistic regression model, age, previous intussusception history, maximum diameter of concentric circles, and lead points were independent risk factors for recurrent intussusception after saline enema.The optimal cut-off values for age and maximum diameter of concentric circles were 2 years and 33.5 mm, respectively, according to ROC curve analysis. Conclusion:Age older than 2 years, previous intussusception history, maximum diameter of concentric circles longer than 33.5 mm, and lead points are independent risk factors for recurrence after saline enema.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective This study was performed to explore the use of intramuscular low-dose Zoletil(1.5 mg/kg)combined with isoflurane inhalation for tracheal intubation in miniature pigs while preserving spontaneous respiration by determining the 50％and 95％minimum alveolar concentrations effective inhaled(MAC EI50 and MAC EI95).The goal was to establish a safe anesthetic method for tracheal intubation in miniature pigs in which intubation is difficult.Methods Forty-four Bama miniature pigs underwent general anesthesia.Following sedation with an intramuscular injection of sufentanil,anesthetic induction was performed using mask inhalation of isoflurane with monitoring of the heart rate,blood pressure,respiration,body temperature,oxygen saturation,end-tidal carbon dioxide concentration,and end-tidal isoflurane concentration.The initial end-tidal isoflurane concentration was set at 2.0％.The tracheal intubation conditions and outcomes were evaluated using Cooper's scoring system,and the dose-response relationship was calculated using Dixon's up-and-down method.Probit regression was employed to calculate the MAC EI50 and MAC EI95 along with their 95％confidence intervals(CI).Results In tracheal intubation using direct laryngoscopy with induction by low-dose sufentanil combined with isoflurane inhalation in miniature pigs,the MAC EI50 was 3.10％(95％CI,2.79％～3.56％)and the MAC EI95 was 3.77％(95％CI,3.41％～6.42％).With proper monitoring and airway management planning in place,alveolar isoflurane concentrations ranging from 3.10％to 3.75％were able to maintain stable vital signs in the miniature pigs.Conclusions The use of Zoletil combined with isoflurane inhalation for tracheal intubation in miniature pigs,aimed at preserving spontaneous breathing,is a preferable and safe anesthetic method for oral airway management in miniature pigs with significant potential for widespread application.

Objective:To explore the relationship between periprosthetic infection and preoperative serum levels of human β-defensin 3 (HBd-3) and interleukin-12 (IL-12) in patients with femoral neck fracture after hip replacement surgery.Methods:A prospective study was conducted to 268 patients with femoral neck fracture who underwent hip replacement surgery at Chengde Central Hospital from April 2020 to April 2022. They were divided into an infected group and an uninfected group based on whether they had periprosthetic infection within 2 weeks after surgery. The baseline data and preoperative laboratory indicators of the two groups were compared, and the relationship between preoperative serum HBd-3 and IL-12 levels and postoperative periprosthetic infection in patients was mainly analyzed.Results:Seventeen out of 268 patients with femoral neck fractures experienced periprosthetic infections after hip replacement surgery, with an infection rate of 6.34%(17/268). The body mass index, operation time, postoperative drainage time and IL-12 in the infected group were higher than those in the uninfected group: (23.75 ± 2.18) kg/m 2 vs. (21.86 ± 1.95) kg/m 2, (124.82 ± 15.93) min vs. (116.92 ± 14.75) min, (57.41±7.81) min vs. (49.65 ± 5.73) min, (64.82 ± 11.59) ng/L vs. (54.23 ± 9.55) ng/L, the preoperative albumin and HBd-3 were lower than those in the uninfected group: (32.56±4.63) g/L vs. (37.25 ± 5.81) g/L, (38.03 ± 6.74) μg/L vs. (46.84 ± 8.93) μg/L, and the differences were statistically significant ( P<0.05). The results of Logistic regression analysis showed that high body mass index, long surgical and postoperative drainage time, and high preoperative IL-12 levels were risk factors for periprosthetic infection after hip replacement surgery in patients with femoral neck fractures ( OR>1, P<0.05), while preoperative serum albumin and HBd-3 levels were protective factors ( OR<1, P<0.05). Receiver operating characteristic curve results showed that preoperative serum HBd-3 and IL-12 alone and in combination predict AUC>0.70 for periprosthetic infection in patients with femoral neck fracture after hip replacement surgery, which had certain predictive value. The restricted cubic spline method combining spline function and Logistic regression was used for analysis, and the results showed a linear dose-response relationship between the levels of HBd-3 and IL-12 and the strength of the association with periprosthetic infection after hip replacement surgery in patients with femoral neck fracture ( P<0.05). Conclusions:Preoperative serum HBd-3 and IL-12 levels are associated with periprosthetic infection in patients with femoral neck fracture after hip replacement surgery, and can serve as predictive indicators for infection occurrence.

Objective:To explore the association between postoperative radiotherapy for bladder cancer and the risk of second primary rectal cancer.Methods:Eligible 75 120 patients with bladder cancer from the Surveillance, Epidemiology, and End Result database (SEER) of the National Cancer Institute (NCI) (1975-2017) were enrolled in this study. The second primary cancers referred to rectal cancers patients suffered after more than five years post-treatment for bladder cancer, and the cumulative incidence was estimated using Fine-Gray competing risk regression. The relative risk (RR) of rectal cancer in patients treated with or without radiotherapy (the RT group or the NRT group) was evaluated using Poisson regression.Results:Among the 75 120 patients, 70 045 (92.4%) were Caucasian, with a median age of 65.8 years (54-74 years). A total of 2 236 (3%) received postoperative radiotherapy, while 72 884 (97%) received surgery alone. The 30-year follow-up revealed a cumulative incidence of rectal cancer of 0.93% in the RT group and 0.43% in the NRT group ( P = 0.004). The competing risk regression analysis identified a significant association between radiotherapy and rectal cancer ( HR: 1.86; 95% CI 1.26-2.74, P < 0.009). Furthermore, the RR of radiotherapy-associated rectal cancer significantly increased as the diagnosis occurred earlier (1975-1985 vs. 1985-1994: RR 2.59; 95% CI 1.20-4.86, P < 0.001), and a lower age at the time of radiotherapy was associated with a higher probability of second primary tumors (≤50-year old vs. > 50 year old : RR 7.89, 95% CI 2.97-21.30, P < 0.001). As calculated using the Poisson distribution, the RR of second rectal tumors was higher in the RT group ( RR: 2.20, 95% CI 1.45-3.18, P < 0.001), even after adjusting the date of diagnosis ( RR: 1.77, 95% CI 1.17-2.57, P = 0.009). Conclusions:An increased risk of rectal cancer following bladder cancer radiotherapy necessitates aggressive follow-ups for the purpose of early detecting second primary rectal cancer associated with bladder cancer radiotherapy.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

OBJECTIVE: To detect the serum level of chemokine CXC motif chemokine 10 (CXCL-10) and Krebs von den lungen-6 (KL-6) in patients with rheumatoid arthritis associated interstitial lung disease (RA-ILD), and to analyze their correlation with RA-ILD, as well as the significance in RA-ILD. METHODS: A total of 169 RA patients were enrolled in the study. According to imaging findings of with and without ILD in high-resolution computed tomography scans of chest, the subjects were divided into RA-ILD group and RA-non-ILD group. According to the inclusion and exclusion criteria, 80 patients in each of the two groups were finally selected. Two groups were matched according to the 1 ∶ 1 ratio using propensity score matching (PSM). The serum CXCL-10 and KL-6 levels were detected by enzyme-linked immunosorbent assay. The clinical features, laboratory data and medications between the two groups were compared after PSM and the correlation between serum levels and clinical parameters were analyzed. Binary Logistic regression was used to analyze the risk factors of ILD in the RA patients, and the predictive value of CXCL-10 and KL-6 in RA-ILD was evaluated. RESULTS: In this study, 49 patients with RA-ILD and 49 patients with RA-non-ILD were selected by PSM. The levels of CXCL-10 and KL-6 in the RA-ILD group [64.36 (34.01, 110.18) ng/L, 360.70 (236.35, 715.05) U/mL] were significantly higher than those in the RA-non-ILD group [29.80 (16.89, 40.55) ng/L, 210.69 (159.98, 255.50) U/mL] (all P < 0.001). The results of correlation analysis showed that the level of serum CXCL-10 was positively correlated with the Warrick score on chest CT (r=0.378, P=0.007) and negatively correlated with the percentage of forced vital capacity to the predicted value (FVC%, r=-0.338, P=0.018). And the level of KL-6 was positively correlated with rheumatoid factor (RF, r=0.296, P=0.039) and negatively correlated with FVC% (r=-0.436, P=0.002) and the percentage of diffusion capacity for carbon monoxide to the predicted value (DLCO%, r=-0.426, P=0.002). Both univariate and multivariate Logistic regression analysis showed that CXCL-10 and KL-6 were positively correlated with ILD, the values of OR were 1.035 and 1.023 in CXCL-10 and those were 1.004 and 1.005 in KL-6 respectively (P < 0.05). The ROC curves were plotted with CXCL-10 and KL-6. The area under the curve (AUC) was 0.770 and 0.752 respectively. The AUC of combined detection increased to 0.800. CONCLUSION Serum levels of CXCL-10 and KL-6 are significantly elevated in patients with RA-ILD and correlated with the severity of ILD. The combined estimate of them helps to improve the effectiveness of diagnosis.

Systemic lupus erythematosus (SLE) is a diffuse, systemic autoimmune disorder that can impact multiple organs and systems, with patients exhibiting abnormal levels of various autoantibodies and immune markers in their serum. It is currently understood that dysregulation of B cells activation plays a pivotal role in the pathogenesis of SLE, as aberrantly activated B cells produce autoantibodies that inflict damage on multiple organs through complement activation and antibody-dependent cell-mediated cyto-toxicity. Traditional therapies for SLE may prove ineffective for certain patients or lead to adverse reactions. In most instances, conventional treatment merely alleviates symptoms and necessitates lifelong immunotherapy. A limited number of clinical cases have explored chimeric antigen receptor T cells (CAR-T) therapy as a potential treatment for autoimmune diseases such as SLE. Research indicates that CAR-T can specifically target CD19 expressed on the surface of B cells and plasma cells, achieving profound depletion while minimizing drug-related side effects. This report details a female patient diagnosed with SLE and lupus nephritis who was successfully treated using dual-targeting B cells maturation antigen CAR-T by our research team; following treatment, she ceased steroid and immunomodulator use, attaining sustained remission without these medications. The patient was a 23-year-old female. Multiple examinations in other hospitals and in our hospital showed positive anti-double-stranded DNA (dsDNA) antibody and low complement C3. Renal biopsy in our hospital showed lupus nephritis Ⅳ-G (A/C), and National Institutes of Health (NIH) activity index (AI) score=4. She was diagnosed with "SLE, lupus nephritis (LN)". She was treated with hormones, immunosuppressants and Chinese medicine, but the effect was not good. After the CAR-T treatment, She stopped using hormones and immune agents and achieved continuous remission with zero hormones and zero immune agents. She became pregnant six months after CAR-T infusion, and gave birth to a healthy full-term, full-weight baby successfully. She is the first patient in China who successfully discontinued hormone, immune preparations and gave birth after CAR-T therapy. During the follow-up of the patient, we found that the immune indexes had basically returned to normal, and the safety was good. It indicates that CAR-T therapy may represent a promising and innovative therapeutic approach for the management of SLE. This offers hope and establishes a precedent for SLE women of childbearing age.
