BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Bio-mineralization has emerged as a promising strategy to enhance vaccine immunogenicity. This study optimized the calcium phosphate (CaP) mineralization process of foot-and-mouth disease virus-like particles (FMD VLPs) to achieve high mineralization efficiency and scalability. Key parameters, including concentrations of Ca²⁺, HPO₄^2-, NaCl, and VLPs, as well as stirring speed, were systematically optimized. Stability of the scaled-up reaction system and immunogenicity of the mineralized vaccine were evaluated. Optimal conditions [25.50 mmol/L Ca(NO₃)₂, 15 mmol/L Na₂HPO₄, 300 mmol/L NaCl, 0.75 mg/mL VLPs, and 1 500 r/min] yielded CaP-mineralized VLPs (VLPs-CaP) with high mineralization efficiency, uniform morphology, and a favorable particle size. Scaling up the reaction by 25 folds maintained consistent mineralization efficiency and particle characteristics. Immunization in mice demonstrated that VLPs-CaP induced higher titers of specific antibodies and neutralizing antibodies than unmineralized VLPs (P < 0.05). Higher IgG2a/IgG1 ratio and enhanced IFN-γ secretion (P < 0.05) further indicated robust cellular immune responses. We establish a stable and scalable protocol for VLPs-CaP, providing a theoretical and technical foundation for developing high-efficacy VLPs-CaP vaccines.

Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ²=9.719, P=0.008), marital status (χ²=8.496, P=0.014), occupations (χ²=19.462, P<0.001), frequencies of dining out (χ²=5.457, P=0.019), previous Hp test results (χ² =4.131, P=0.042) and test results after treatment (χ²=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.

Objective:To access the therapeutic efficacy of newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage for severe acute cholangitis caused by choledocholithiasis.Methods:Data of 26 patients were retrospectively analyzed, who were admitted into the intensive care unit (ICU), Zhongda Hospital, Southeast University, due to choledocholithiasis induced by severe acute cholangitis and underwent cholangioscope-assisted bedside one-stage lithotomy and biliary drainage from June 2020 to February 2022. Clinical outcomes were analyzed.Results:The time interval from disease onset to endoscopic intervention was 36.2±15.5 hours, with 7.2±4.9 hours from ICU admission to endoscopic intervention. Technical success rate was 100.0% in one-stage stone removal and biliary drainage. Except for one mild pancreatitis, no other complication occurred. Acute physiology and chronic health evaluation (APACHE)Ⅱ and sequential organ failure assessment (SOFA) scores prior to endoscopic intervention were 25.2±6.6 and 11.9±3.5, respectively. APACHE Ⅱ scores at day 1, 3, and 7 after endoscopic intervention were 21.7±6.5, 17.2±6.8 and 12.7±7.7, respectively, and SOFA scores were 10.6±2.9, 8.4±3.0 and 5.4±3.7, respectively, all of them were lower than those before operation ( P<0.001). The lengths of ICU stay and total hospitalization were 9.7±5.0 days and 12.8±4.5 days, respectively. In-hospital mortality occurred in 3 (11.5%) patients. According to a 6-month follow-up, one patient died of pneumonia, and another died of acute myocardial infarction. No acute cholangitis re-occurred in those survivors. Conclusion:Newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage demonstrate significant improvements in prognosis, highlighting its safety in managing severe acute cholangitis.

Actinomycosis is a rare chronic granulomatous disease characterized by granuloma formation and tissue fibrosis with sinus tracts,often misdiagnosed due to its similarity to many infectious and non-infectious diseases.This report presents a case of a 60-year-old female with more than 10 years history of rheumatoid arthritis who developed actinomycosis infection after long-term treatment with immunosuppressants and biologics,including methotrexate,leflunomide,and infliximab,leading to recurrent joint pain,poorly controlled rheumatoid arthritis activity,and persistent elevation of white blood cell counts.Abdominal CT revealed a pelvic mass and right ureteral dilation.Pathological examination of cervical tissue showed significant neutrophil infiltration and sulfur granules,indicating actinomycosis.The patient received 18 months of doxycycline treatment for the infection and continued rheumatoid arthritis therapy with leflunomide,hydroxychloroquine sulfate,and tofacitinib,resulting in improved joint symptoms and normalized white blood cell counts.After 2 years of follow-up,the patient remained stable with no recurrence.This case highlights the importance of clinicians being vigilant for infections,particularly chronic,occult infections from rare pathogens,in rheumatoid arthritis patients on potent immunosuppressants and biologics,advocating for early screening and diagnosis.

Objective:To compare the effects of different multisensory stimulation on the oral feeding time of premature infants in the Neonatal Intensive Care Unit (NICU), so as to provide a theoretical basis for further implementing multisensory stimulation in clinical practice.Methods:The randomized controlled trial on the effect of multisensory stimulation on the oral feeding in NICU premature infants was systematically searched in both Chinese and English databases. The search period was from database establishment to October 24, 2023. After literature screening and data extraction, the quality of the included literature was evaluated using the Cochrane risk of bias tool for randomized controlled trials, and Bayesian network Meta-analysis was performed using Stata 18.0 software.Results:A total of 39 randomized controlled trials were included, involving 8 different combinations of multisensory stimulation, namely tactile auditory combined stimulation, olfactory taste combined stimulation, tactile taste combined stimulation, auditory taste combined stimulation, tactile kinesthetic combined stimulation, tactile taste olfactory combined stimulation, tactile auditory visual vestibular combined stimulation, and tactile auditory visual vestibular olfactory taste combined stimulation. The network Meta-analysis showed that the taste auditory combined stimulation had the best effect on shortening the transition time of oral feeding in NICU premature infants ( P<0.05), while the tactile taste combined stimulation had the best effect on shortening the complete oral feeding time in NICU premature infants ( P<0.05) . Conclusions:Multisensory stimulation can shorten the oral feeding time of NICU premature infants to varying degrees, among which taste intervention is important, and the effects of tactile sensation and auditory sensation are differentiated. Attention should be paid to the effect of the taste tactile auditory combined stimulation on the oral feeding time of NICU premature infants, and further exploration should be conducted on the impact of the duration and frequency of multisensory stimulation on the intervention effect.

ObjectiveTo establish the identification method of Dalbergiae Odoriferae Lignum（DOL） and its counterfeits by nuclear magnetic resonance hydrogen spectrum（¹H-NMR） combined with multivariate statistical analysis. Method¹H-NMR spectra of DOL and its counterfeits were obtained by NMR， and the full composition information was established and transformed into a data matrix， and the detection conditions were as follows：taking dimethyl sulfoxide-d₆（DMSO-d₆） containing 0.03% tetramethylsilane（TMS） as the solvent， the constant temperature at 298 K（1 K=-272.15 ℃）， pulse interval of 1.00 s， spectrum width of 12 019.23 Hz， the scanning number of 16 times， and the sampling time of 1.08 s. Similarity examination and hierarchical cluster analysis（HCA） were performed on the data matrix of DOL and its counterfeits， and orthogonal partial least squares-discriminant analysis（OPLS-DA） was used to analyze the data matrix and identify the differential components between them. In the established OPLS-DA category variable value model， the category variable value of DOL was set as 1， and the category variable value of the counterfeits was set as 0， and the threshold was set as ±0.3， in order to identify the commercially available DOL. The OPLS-DA score plot was used to determine the types of counterfeits in commercially available DOL， and it was verified by thin layer chromatography（TLC）. ResultThe results of similarity analysis and HCA showed that there was a significant difference between DOL and its counterfeits. OPLS-DA found that the differential component between DOL and its counterfeits was trans-nerolidol. The established category variable value model could successfully identify the authenticity of the commercially available DOL. The results of the OPLS-DA score plot showed that there were heartwood of Dalbergia pinnata and D. cochinchinensis in the commercially available DOL， and were consistent with the TLC verification results. ConclusionThere is a phenomenon that heartwood of D. pinnata and D. cochinchinensis are sold as DOL in the market. ¹H-NMR combined with multivariate statistical analysis can effectively distinguish DOL and its counterfeits， which can provide a reference for the identification of them.
