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.

A complete plant body consists of elements on different scales, including microscopic molecules, mesoscopic multicellular structures, and macroscopic tissues and organs, which are interconnected to form complex biological networks. The growth and development of plants involve the regulation of elements on different scales and their biological networks, which requires the coordinated operation of multiple molecules, cells, tissues, and organs. It is difficult to reveal the essence of multi-level life activities by a single method or technology. In recent years, the development of various novel imaging technologies has provided new approaches for revealing the complex life activities in plants. Using multi-modal imaging technologies to study the cross-scale network connections of plants from the microscopic, mesoscopic, and macroscopic levels is crucial for understanding the complex internal connections behind biological functions. This paper first summarizes multi-modal cross-scale imaging technologies, three-dimensional reconstruction, and image processing methods, outlines the basic framework of cross-scale network connection properties, and then summarizes the applications of multi-modal imaging technologies in elucidating plant multi-scale networks. Finally, this review systematically integrates the combined analysis of cross-scale 3D spatial structural data and single-cell omics, laying a theoretical foundation for the innovation of novel plant imaging technologies. Furthermore, it provides a new research paradigm for in-depth exploration of the interaction mechanisms among cross-scale elements and the principles of biological network connectivity in plant life activities.

Objective:To summarize the experience of designing transplanted hair based on the orbital morphology and tissue characteristics for the treatment of eyebrow defects after burns.Methods:A retrospective analysis was conducted on clinical data of the patients with eyebrow defects after burns who treated at Hair Transplantation Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences between January 2011 and September 2023. The location and appearance of eyebrow were designed according to the orbital morphology and tissue characteristics. The follicles were extracted by incision of scalps strips and follicle unit excision (FUE) on the donor area of the occipital region near the posterior hairline or the posterior ear hairline. Scalps with scars that needed to be removed or had "dog ear" deformities following scalp expansion surgery that needed to be repaired were also be used as donor sites. The follicles were divided as follicle units (FUs) including single hair. The recipient area was punched with syringe needle of 22 or 22 G to subcutaneous superficial layer. Then the hair shaft was clamped with microforceps and the hairs were transplanted to the defective area to restore the appearance of eyebrow. The density, morphology, direction and scars of the donor sites were observed by following-ups.Results:A total of 197 patients with 282 eyebrows were recruited. There were 133 males and 64 females. The average age was 33.7 (9 to 62) years. There were 17 patients with skin graft transplantation in the eyebrow arch, 33 with flap and expanded flap repair, 36 with eyelid skin grafting, 111 with burn scar healing. A total of 51 patients had complete eyebrow defects on both sides, and 34 had partial defects. Sixty-five patients had complete eyebrow defects on single side, and 47 had partial defects. The amount of hair transplantation was from 53 to 600 FUs on 282 eyebrows. Seventy-five patients extracted follicles with incision of scalps strips and 122 with FUE. The patients were followed up for 9 months to 10 years. Folliculitis were found in 17 patients and completely cured by 75% alcohol disinfection. Nine patients with insufficient density underwent hair transplantation for a second time to increase the density of hairs one year later. And the implanted hairs grew well, which were similar to the shape and direction of normal eyebrows. Transplanted hairs of the rest patients grew well. The direction and appearance were satisfied. The scar in the donor site was not obvious.Conclusion:The transplanted hair should be designed primarily based on the orbital morphology and tissue characteristics for the treatment of eyebrow defects after burns. Then the position of the eyebrow and the bilateral symmetry should be considered. The ideal effect of eyebrow reconstruction would depend on the full consideration of the receipt site.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

The aim of this study is to establish a simple and accurate method for vaccine immune e-valuation of porcine pseudorabies virus.In this research,PRV-gD recombinant protein was ex-pressed from mammalian cell HEK-293F as coating antigen,and then the reaction conditions of gD-iELISA were optimized according to checkerboard titration method.The gD-iELISA was used to detect the antibody levels of 211 clinical pig serum samples and the consistency with the neu-tralizing antibody levels wasanalyzed.The results showed that the antigen coating concentration was 0.90 mg/L;the serum to be detected was diluted 1∶100 and incubated at 37 ℃ for 30 min;goat anti-pig IgG-HRP antibody was diluted 1∶55 000 and incubated at 37 ℃ for 30 min;TMB sub-strate was developed at 37 ℃ for 20 min.The method could detect 1∶6 400 diluted PRV positive serum.The results of CSFV,PRRSV,PCV-2,PEDV and FMDV positive sera were all negative by gD-iELISA,and there was no cross-reaction between the method and the above positive sera.The coincidence rate of gD-iELISA and commercial kits was 95.26％,and the intra-and inter-batch co-efficients of variation were both less than 10％.Correlation analysis showed that the correlation coefficient(r)between gD antibody level and neutralizing antibody level was significantly greater than that of gB antibody level,and the gD antibody level had a good linear relationship with the neutralizing antibody level.The results indicated that gD-iELISA was more suitable for vaccine im-mune evaluation of PRV than gB-iELISA.Therefore,the method will have a good prospect of ap-plication in the immunization control of the PRV.

Objective: Cardiac magnetic resonance (CMR) is a diagnostic tool that provides precise and reproducible information about cardiac structure, function, and tissue characterization, aiding in the monitoring of chemotherapy response in patients with lightchain cardiac amyloidosis (AL-CA). This study aimed to evaluate the feasibility of CMR in monitoring responses to chemotherapy in patients with AL-CA. Materials and Methods: In this prospective study, we enrolled 111 patients with AL-CA (50.5% male; median age, 54 [interquartile range, 49–63] years). Patients underwent longitudinal monitoring using biomarkers and CMR imaging. At followup after chemotherapy, patients were categorized into superior and inferior response groups based on their hematological and cardiac laboratory responses to chemotherapy. Changes in CMR findings across therapies and differences between response groups were analyzed. Results: Following chemotherapy (before vs. after), there were significant increases in myocardial T2 (43.6 ± 3.5 ms vs. 44.6 ± 4.1 ms; P = 0.008), recovery in right ventricular (RV) longitudinal strain (median of -9.6% vs. -11.7%; P = 0.031), and decrease in RV extracellular volume fraction (ECV) (median of 53.9% vs. 51.6%; P = 0.048). These changes were more pronounced in the superior-response group. Patients with superior cardiac laboratory response showed significantly greater reductions in RV ECV (-2.9% [interquartile range, -8.7%–1.1%] vs. 1.7% [-5.5%–7.1%]; P = 0.017) and left ventricular ECV (-2.0% [-6.0%–1.3%] vs. 2.0% [-3.0%–5.0%]; P = 0.01) compared with those with inferior response. Conclusion Cardiac amyloid deposition can regress following chemotherapy in patients with AL-CA, particularly showing more prominent regression, possibly earlier, in the RV. CMR emerges as an effective tool for monitoring associated tissue characteristics and ventricular functional recovery in patients with AL-CA undergoing chemotherapy, thereby supporting its utility in treatment response assessment.

Objective:To observe any effect of combining extracorporeal shock wave stimulation with proprioceptive neuromuscular facilitation (PNF) on the lower limb motor function of stroke survivors with foot drop.Methods:Thirty-six stroke survivors with foot drop were randomly divided into an extracorporeal shock wave group, a PNF group and a combination group, each of 12. The extracorporeal shock wave group and PNF group were given those therapies alone, while the combination group was provided with both. The extracorporeal shock wave therapy protocol was 2000 times on each muscle at an intensity of 2.5 bar and a frequency of 10Hz, twice a week for 4 weeks, while the PNF was provided at least 3 times per week for 4 weeks. Before and after the intervention, all of the participants were evaluated using the modified Ashworth scale (MAS), the 10-metre walk test (10 MWT) and the Fugl-Meyer lower limb motor function scale (FMA). Active range of the ankle joint and toe out angle were also observed.Results:After the intervention the lower limb muscle tone had decreased significantly in 8 of the PNF group members and in 9 of those in the extracorporeal shock wave group, but it has decreased significantly in all 12 members of the combination group. And the average magnitude of the improvement was also significantly greater in the combination group than in the other two groups. Moreover, significant differences were observed in the active range of the ankle joint after the treatment in the combination group, but not in the other two groups. After the intervention the average 10 MWT times and FMA scores of the PNF and combination groups had improved significantly, but not those of the extracorporeal shock wave group, but significant improvement in toe out angles was observed in all three groups, though the average improvement in the combination group was significantly greater than in the other 2 groups.Conclusion:Combining extracorporeal shock waves with PNF can effectively improve the lower limb motor function of stroke survivors with foot drop.

Periodontitis is a chronic inflammatory disease that destroys the integrity of tooth-supporting tissue. Periodontitis is listed as a major oral disease by the World Health Organization and is a public-health problem affecting global oral and systemic health. The fourth national oral health epidemiological survey has revealed that periodontitis is one of the most common oral problems in China. With the development of science and medicine, increased attention is being paid to the importance of oral health and its influence on general health. Accordingly, stomatologists are required to master more relevant information on clinical diagnosis and treatment, as well as to pay more attention to the diagnosis and treatment methods of patients with different systemic diseases. This article expounds the diagnosis and treatment strategy of patients with systemic disease periodontitis. We aimed to help stomatologists make more reasonable diagnosis and treatment decisions.
