Objective To explore the effect of the ratio of high-density lipoprotein cholesterol(HDL-C)/total cholesterol(TC)on no-reflow after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS)complicated with diabetes mellitus(DM).Methods A retrospective analysis was conducted on 206 elderly ACS patients complicated with DM undergoing PCI in our hospital from January 2018 to August 2024.The HDL-C and TC levels were detected by cholesterol oxidase test,and the HDL-C/TC ratio was calculated.Coronary angi-ography(CAG)was applied to evaluate no-reflow phenomenon after PCI,and according to the re-sults,the patients were divided into a non-reflow group(41 cases)and a normal reflow group(165 cases).ROC curve was plotted to evaluate the predictive performance of HDL-C/TC ratio for no-reflow after PCI in patients with ACS complicated DM.Results The no-reflow group had signifi-cantly higher TC and glycated hemoglobin A1c(HbA1c)levels and more balloon dilatations,but lower HDL-C level and HDL-C/TC ratio than the normal flow group(P＜0.01).Multivariate lo-gistic regression analysis showed that HbA1c(OR=3.196,95％CI:1.619-6.310,P=0.001),number of balloon dilatations(OR=3.504,95％CI:1.807-6.797,P=0.000),and HDL-C/TC ra-tio(OR=3.927,95％CI:2.0 73-7.441,P=0.000)were influencing factors of no-reflow after PCI in patients with ACS and DM.The AUC value of HDLC,TC,and HDL-C/TC ratio in predicting no-reflow after PCI was 0.842,0.726,and 0.922,respectively.Conclusion HDL-C/TC ratio is an influencing factor for no-reflow in patients with ACS and DM after PCI.The ratio at a cut-off val-ue of ≤0.21 has a certain predictive value for no-reflow after PCI in these elderly patients.

BackgroundPostpartum depression （PPD） is a prevalent postpartum complications that significantly compromises women's psychological and physical well-being. Repetitive transcranial magnetic stimulation （rTMS）， a conventional neuromodulation technique， has been increasingly used in the treatment of PPD. However， high-quality evidence regarding its efficacy and safety remains limited. ObjectiveTo evaluate the efficacy and safety of rTMS in the treatment of PPD， thereby providing references for clinical treatment. MethodsDatabases including Cochrane Library， PubMed， Embase， CNKI， Wanfang， VIP and China Biology Medicine disc （CBM） were electronically searched for randomized controlled trials （RCTs） on rTMS for PPD， with the search spanning from database inception to February 8， 2025. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1， and the certainty of evidence was graded according to the Grading of Recommendations Assessment， Development and Evaluation （GRADE） approach. Meta-analysis was conducted using RevMan 5.3 and Stata 12.0. The outcomes of the Meta-analysis included the total effective rate， Edinburgh Postnatal Depression Scale （EPDS） score， Hamilton Depression Rating Scale （HAMD） score， and adverse reactions （dizziness， headache， nausea， diarrhea， and the overall incidence of adverse reactions）. ResultsA total of 11 studies involving 729 patients with PPD were included. Meta-analysis results showed that the total effective rate in the study group was significantly higher than that in the control group （OR=5.54， 95% CI： 3.07–10.01， P<0.01）. Both EPDS score （SMD=-2.38， 95% CI： -3.39–-1.37， P<0.01） and HAMD score （SMD=2.53， 95% CI： 1.21–3.85， P<0.01） in the study group were significantly lower than those in the control group， with statistically significant differences. Comparisons between the study group and control group reveal no significant differences in the incidence of dizziness and headache （RR=1.47， 95% CI： 0.63–3.43， P>0.05）， nausea （RR=1.46， 95% CI： 0.55–3.86， P>0.05）， diarrhea （RR=0.71， 95% CI： 0.23–2.20， P>0.05）， and overall adverse reactions （RR=1.30， 95% CI： 0.79–2.15， P>0.05）. GRADE assessment rated the four indicators of dizziness and headache， diarrhea， overall incidence of adverse reactions， and EPDS score as "moderate-certainty evidence"， and rated the total effective rate， nausea， and the HAMD score as "low-certainty evidence". ConclusionrTMS demonstrates certain therapeutic efficacy for PPD， with a safety profile comparable to conventional treatment. ［Funded by Sichuan Psychological Society Research Planning Project （number， SCSXLXH202403099）； Guiding Science and Technology Plan Project of Guangyuan （number， 23ZDYF0095）］

To summarize the diagnosis and management of a highly sensitized renal transplant recipient who developed Legionella pneumophila infection during the perioperative period. A 48-year-old male recipient presented early after transplantation with both acute allograft rejection and pulmonary infection. The acute rejection episode was successfully reversed with appropriate treatment, whereas the pulmonary infection continued to progress. Initial microbiological tests were negative, and empirical antimicrobial therapy was ineffective. Legionella pneumophila was subsequently detected by metagenomic next-generation sequencing of bronchoalveolar lavage fluid obtained via bronchoscopy. Following combined therapy with moxifloxacin and tigecycline, along with withdrawal of immunosuppressive agents, the pulmonary lesions completely resolved.

This report described one human leukocyte antigen pre-sensitized recipient undergoing preoperative plasmapheresis (PP), intravenous immunoglobulins (IVIG) desensitization and immune induction therapy before kidney transplantation with a donor kidney. Early postoperative clinical diagnosis was acute antibody-mediated rejection (AMR). A marked elevation of donor-specific antibodies (DSA) was accompanied by a decline of renal function. PP/IVIG dosing failed to lower the level of DSA. After low-dose splenic irradiation, DSA level dropped steadily and transplanted kidney function normalized. Thus adjuvant low-dose splenic irradiation may eliminate DSA immediately without a rebound.

Objective:To explore the efficacy and safety of daratumumab in late antibody-mediated rejection (late AMR) after kidney transplantation (KT).Methods:From December 2020 to December 2021, the relevant clinical data were reviewed for 8 patients with late AMR after receiving daratumumab at Affiliated Tongji Hospital. In intensive phase, the combination of plasma exchange (PP)/intravenous immunoglobulin (IVIG) and daratumumab were dosed once a week; in maintenance phase, once every 2 to 4 weeks. The levels of donor-specific antibody (DSA) and renal function were compared pre-treatment and Month 3/12 post-treatment. The treatment-related toxicities were observed. Independent sample T test was utilized for inter-group comparison.Results:The median treatment course during intensive period was 9(4-17) sessions. Maintenance treatment lasted for 5 to 19 months and 2 cases withdrew after 5 to 6 treatments for achieving antibody clearance. A total of 11 DSAs were detected in 8 recipients. At Month 3/12, mean fluorescent intensity (MFI) of DSA was 6 016±4 775 and 6 438±3 668. Both were significantly lower than 11 944±5 237 pre-treatment and the difference was statistically significant ( P=0.012, 0.004). Seven recipients achieved stable renal function during treatment and one recipient resumed hemodialysis at Month 18 due to acute rejection. Glomerular filtration rate of 7 recipients was (40.6±20.1), (53.6±20.9) and (49.0±17.2) ml·min -1· (1.73 m 2) -1 pre-treatment and Month 3/12 and no significant differences existed among different timepoints. During follow-ups, 2 cases developed mild nasal congestion during an early stage of daratumumab infusion while the remainders had no obvious discomfort during infusion and tolerance was decent. Conclusion:Early combination of daratumumab with PP/IVIG, followed by a course of daratumumab has demonstrated an excellent antibody reduction effect on late AMR. During treatment, renal function remains generally stable.

Objective To analyze the sensitivity of ARHGAP8 in predicting the efficacy of neoadjuvant chemotherapy in the patients with locally advanced mid-low colorectal cancer and provide accurate evidence for the treatment of advanced colorectal cancer.Methods The differentially expressed gene ARHGAP8 was screened out by bioinformatics analysis.Cancer tissue and rectal tissue of 68 patients with primary rectal cancer were select-ed.The rectal cancer tissue samples and the rectal tissue samples were collected for clinical validation of ARH-GAP8 expression by quantitative real-time PCR,Western blotting,and immunohistochemistry.The clinical and pathological features such as gender,age,tumor stage,differentiation degree,and pathological type of the pa-tients were collected for functional validation.Forty-four patients with locally advanced mid-low rectal cancer who received neoadjuvant chemotherapy were selected for immunohistochemical examination of ARHGAP8 expres-sion.The expression level of ARHGAP8 was compared between before and after chemotherapy and among different efficacy groups.Results The bioinformatics analysis revealed differences in the expression level of ARHGAP8 between the cancer tissue and rectal tissue(P＜0.001).The expression level of ARHGAP8 was correlated with tumor stage(P=0.024),lymph node metastasis(P=0.007),and age(P=0.005).Quantitative real-time PCR results showed that the mRNA level of ARHGAP8 in the cancer tissue was higher than that in the rectal tis-sue(P＜0.001).Western blotting and immunohistochemistry results demonstrated that the protein level of ARH-GAP8 in the cancer tissue was higher than that in the rectal tissue(P=0.011).The expression of ARHGAP8 was correlated with tumor size(P=0.010)and pathological stage(P=0.005),while it showed no significant association with tumor differentiation degree,lymph node metastasis,liver metastasis,Ki-67,or microsatellite instability expression level.The 44 patients receiving neoadjuvant chemotherapy included 13,8,8,and 15 pa-tients of tumor regression grades 0,1,2,and 3,respectively.Among them,65.91％(29/44)patients showed responses to the treatment.After neoadjuvant chemotherapy,the expression of ARHGAP8 in the cancer tissue was down-regulated in the patients who responded to the chemotherapy(P＜0.001).The response rate in the patients with low protein level of ARHGAP8 was 92.86％,which was higher than that(53.33％)in the patients with high pro-tein level of ARHGAP8(P=0.033).Conclusions ARHGAP8 is highly expressed in the rectal cancer tissue.The pa-tients with locally advanced mid-low rectal cancer and low ARHGAP8 expression are more sensitive to neoadjuvant chemotherapy with the XELOX protocol.ARHGAP8 can serve as a potential biomarker for the occurrence and develop-ment of rectal cancer and an important index for evaluating the efficacy of neoadjuvant chemotherapy with the XELOX protocol in the patients with locally advanced mid-low rectal cancer.

Objective To investigate the therapeutic effectiveness of ozone combined with low-temperature plasma coagulation therapy on patients with cervical spondylotic radiculopathy and its influence on inflammatory responses.Methods Ozone in combination with low-temperature plasma radio-frequency coagulation was applied to 75 patients with cervical spondylotic radiculopathy in Pain Medicine Department of Capital Medical University Affiliated Beijing Anzhen Hospital from May 2022 to May 2023.Pain scores were assessed using Visual Analog Scale(VAS)and Neck Disability Index(NDI)before and two weeks after treatment.Enzyme-linked immunosor-bent assay(ELISA)was used to analyze the level of tumor necrosis factor-alpha(TNF-α),interleukin-6(IL-6)and interferon-gamma(IFN-γ)before and two weeks after treatment.Results After treatment with ozone plus low-temperature plasma radiofrequency,VAS and NDI scores showed a significant decrease[VAS:5.36(4,7)vs.1.32(1,2),P＜0.000 1;NDI:32.72(24,70)vs.7.62(3.55,8.9),P＜0.000 1].Two weeks after surgical intervention,there was an effective reduction in the level of IL-6,TNF-αand IFN-γ alleviating the inflammatory re-sponse[IL-6:4.33(2.51,5.04)vs.3.49(2.08,4.43),P＜0.05;TNF-α:1.95(1.41,2.21)vs.1.61(1.02,2.03),P＜0.05;IFN-γ:1.84(1.18,2.47)vs.1.55(0.76,2.09),P＜0.05].Conclusions This Ozone combined with low-temperature plasma radiofrequency ablation is an effective technology for treatment of cer-vical spondylotic radiculopathy.
