Critically ill patients are at high risk for hospital acquired infections, which can significantly increase the mortality rate and treatment costs for these patients. Therefore, in the process of treating the primary disease, strict prevention and control of new hospital infections is an essential component of the treatment for critically ill patients. The treatment of critically ill patients involves multiple steps and requires a concerted effort from various aspects such as theory, management, education, standards, and supervision to achieve effective prevention and control of hospital infections. However, there is currently a lack of unified understanding and standards for hospital infection prevention and control. To address this, in March 2024, a group of experts in critical care medicine, infectious diseases, and hospital infection from China discussed the current situation and issues of hospital infection control in the intensive care unit together. Based on a review of the latest evidence-based medical evidence from both domestic and international sources, 2024 Expert Consensus on Hospital Acquired Infection Control Principles in the Department of Critical Care Medicine was formed, aiming to provide a basis for the development of hospital infection prevention and control strategies in the field of critical care medicine.

Objective:To explore the psychological experience and demand of parents of children with delayed recovery after congenital heart disease surgery.Methods:This study adopted phenomenological research methods from qualitative research. Using the purposive sampling method, parents of postoperative delayed recovery children with congenital heart disease who met the inclusion criteria were selected as the research objects from October to November 2019 at Fuwai Hospital, Chinese Academy of Medical Sciences. Semi-structured interviews were conducted with the parents of the children, and the data were analyzed by Colaizzi 7-step analysis method.Results:Finally, 13 parents of children with delayed recovery after congenital heart disease surgery were included. According to the interview results, four themes were extracted, which were negative psychological experience of parents of children with delayed recovery, positive psychological experience and expectation change of parents, heavy economic burden of parents and diversified needs of parents.Conclusions:During the delayed recovery period, psychological experience of parents is complex and their needs are diverse. The nursing staff should identify and pay attention to the causes of the negative psychological experience of the parents of the children, timely channel their negative emotions and strengthen the positive psychological experience in many aspects. They can assist parents to seek social help to reduce physical and mental pressure and meet the diverse needs of parents by providing high-quality nursing services and multi-channel information support.

Objective:To construct an analytic method aimed at the characteristics of the commonly method of supplementing and pouring of acupuncture based on the analysis and modeling of ultrasound images around acupoint region in the process of acupuncture.Methods:A total of 7 healthy subjects who underwent physical examination in Beijing Zhongguancun Hospital from June,2022 to June,2023 were selected,and their Kongzui acupoints were acupunctured by 10 acupuncturists with associate senior title as 4 kinds of acupuncture manipulations included reinforcing by twisting and rotating(RFTR),reducing by twisting and rotating(RDTR),reinforcing by lifting and thrusting(RFLT),and reducing by lifting and thrusting(RDLT).The B-ultrasound diagnostic device was used to collect the images of muscle and fascial tissue below the acupoint,so as to construct the model of images.The definition of virtual acupuncture point was adopted to study the regulation of perturbation of subcutaneous tissue that was caused after the skin was acupunctured by needle.The change regulation of the virtual acupuncture point of muscle bundle below skin at Zuikong acupoint of subjects was analyzed.Results:The difference value of average absolution value between peak and trough of the trajectory of virtual acupuncture point of twisting and rotating was 0.066±0.045,and the average value of amplitude of this method was less than that(0.428±0.276)of lifting and thrusting method,and the twisting and rotating method was uniform and symmetrical,and there was difference between two kinds of acupuncture methods.The characteristics of computer graphics was used to qualify the work effect of lifting and thrusting,and reinforcing and reducing,which showed the heavy insertion and light lifting of RFLT,and showed heavy lifting and light insertion of RDLT,thus distinguished the two methods[(RFLT)and(RDLT)].Conclusions:The ultrasound imaging and computer graphics can be used to analyze the regularity of the common"reinforcing and reducing"method of acupuncture and moxibustion.

Objective To investigate the impact of overweight on the prognosis of patients with acute mild ischemic stroke or moderate-high risk transient ischemic attack (TIA). Methods A total of 366 patients with acute mild ischemic stroke or moderate-high risk TIA who carried CYP2C19 loss-of-function alleles were included in the study. Baseline data were collected at admission, and clinical outcomes were collected within 3 months post-onset (primary outcomes: stroke recurrences within 3 months post-onset; secondary outcomes: composite outcome of stroke recurrence or death within 3 months post-onset, vascular events, and quality of life within 3 months). Kaplan-Meier method was used to plot the cumulative incidence curve of outcomes. Multivariate Cox proportional hazards model and multivariate Logistic regression model were used to evaluate the relationship between overweight and clinical outcomes within 3 months post-onset in patientswith ischemic stroke or TIA. The integrated discrimination improvement index (IDI) and net reclassification improvement index (NRI) were calculated to assess the predictive value of adding body mass index (BMI, whether overweight or not) based on traditional models for predicting the prognosis of acute ischemic stroke or TIA. Results After 3 months of follow-up, 28 patients had stroke recurrence, 1 patient died, and 31 patients had vascular events. The Kaplan-Meier cumulative incidence curve showed that the cumulative incidences of stroke recurrence, stroke recurrence or death, and vascular events after 3 months of onset were lower in overweight patients compared with non-overweight patients (Log-rank P < 0.05). Multivariate analysis showed that compared with non-overweight patients, overweight patients had significantly reduced risks of stroke recurrence within 3 months (HR=0.24; 95%CI, 0.08 to 0.71), composite outcome of stroke recurrence or death (HR=0.24; 95%CI, 0.08 to 0.69), and vascular events (HR=0.22; 95%CI, 0.07 to 0.63), and significantly improved quality of life within 3 months (OR=0.39; 95%CI, 0.20 to 0.76). The IDI and NRI calculations showed that compared with traditional models, the new model adding BMI (whether overweight) had significantly improved predictive ability for the prognosis of acute ischemic stroke or TIA. Conclusion Overweight may be a protective factor for the prognosis of TIA patients with acute mild ischemic stroke or moderate-high risk who carry CYP2C19 loss-of-function alleles. Compared with non-overweight patients, overweight patients have reduced risks of stroke recurrence, composite outcome of stroke recurrence or death, and vascular events within 3 months post-onset, and improved quality of life within 3 months post-onset.

Objective:To investigate whether endoplasmic reticulum aminopeptidase 1 ( ERAP1) is a susceptible gene for pre-eclampsia (PE) and the possible mechanism in the pathogenesis. Methods:This retrospective study included 990 PE patients (case group) and 1 240 healthy pregnant women (control group) in six prefecture-level tertiary hospitals in Shandong Province, including the Affiliated Hospital of Qingdao University and Zaozhuang Maternal and Child Health Hospital, from September 2018 to April 2021. Peripheral blood were collected for DNA extraction. Single-nucleotide polymorphisms in the ERAP1 gene (rs30187, rs27044, and rs469783 loci) were analyzed by Taqman probe polymerase chain reaction (PCR). Two missense mutant plasmids, rs30187(c.1583A>G) and rs27044(c.2188C>G), were constructed by point mutation induction based on wild-type plasmids. Six groups (knock-down control, knock-down, over-expression control, over-expression, variant 1 and 2 groups) were set up in this study. After transfecting Htr8 cells with different transfection molecules, the expression of ERAP1 at mRNA and protein levels were detected. Besides, the effects of different transfections on cell function were detected using Transwell migration assay, Transwell invasion assay, cell scratch assay, and CCK-8 assay. Statistical analysis was performed using two independent samples t-test, rank sum test, and Chi-square test. Results:(1) There were significant differences in the genetic distribution of rs30187 (Genotype: χ2=29.25, Allele: χ2=4.68) and rs469783 (Genotype: χ2=7.01, Allele: χ2=6.45) as well as the genotype distribution of rs27044 ( χ2=28.95) between the case group and the control group (all P<0.05). Statistical analysis of the genetic model revealed that rs30187 and rs27044, both recessive models, were statistically different between the two groups with a higher frequency of CC genotypes in the case group ( χ2=20.82 and 19.97, both P<0.05), but a lower frequency in CC dominant gene pattern for rs469783 ( χ2=5.82, P=0.016). (2) Compared with the knock-down control group, the knock-down group showed significantly inhibited expression of ERAP1 (mRNA: 0.5±0.1 vs 1.0±0.0, t=7.49; protein: 0.4±0.1 vs 0.7±0.1, t=2.81; both P<0.05), reduced cell migration rate after 48 h of scratching [(16.5%±1.8%) vs (23.8%±2.4%), t=3.33, P=0.031] and decreased number of cells crossing Transwell chambers after 24 h of culture (423.7±21.3 vs 499.0±24.6, t=3.29, P=0.031). Compared with the over-expression group, variant 1 group and variant 2 group showed significantly inhibited expression of ERAP1 at mRNA (both P<0.001) and protein ( P=0.003 and 0.006) levels after transfection, decreased number of cells crossing Transwell chambers ( P=0.001 and 0.032) and down-regulated cell migration rate after 48 h of scratching [variant 1: P=0.004; variant 2: (21.1±4.6)% vs (28.3±1.1)%, t=2.10, P=0.099]. ERAP1 expression at both mRNA ( P<0.001) and protein ( P=0.008) levels, as well as cell proliferation ( P<0.001) and invasion ability ( P<0.001), were all enhanced in the over-expression group than those in the over-expression control group. Moreover, the migration rate of cells after 48 h of scratching ( P=0.002) and the number of cells crossing Transwell chambers after 24 h of culture ( P=0.001) were also increased. Conclusions:The rs30187, rs27044, and rs46978 on ERAP1 gene were all associated with PE susceptibility, with more carriers of the CC genotype in PE patients at rs30187 and rs27044 loci and more carriers of the CC genotype in healthy gravida at rs469783 locus. ERAP1 may be involved in the pathogenesis of PE by affecting the migratory and invasive ability of trophoblast cells.

Objective:To examine the survival and influential factors of an integrated approach of novel agents, autologous hematopoietic stem cell (auto-HSCT) , and maintenance therapy in patients with multiple myeloma (MM) patients from a single center over the past 15 years.Methods:In our center, 300 MM patients who received an integrated strategy of new agents, auto-HSCT, and maintenance therapy over 15 years were retrospectively and prospectively analyzed.Results:The complete remission rates (CR) and ≥very good partial remission rates (VGPR) following induction therapy, transplantation, and maintenance therapy were respectively 35.3% and 55.2% , 72.4% and 80.0% , 89.2% , and 93.4% . When compared to patients receiving double-drug induction, the ≥VGPR and ORR of patients receiving triple-drug induction were improved. No difference existed in CR, ≥VGPR, and ORR between the PAD (bortezomib + liposome doxorubicin+ dexamethasone) and RAD (lenalidomide + liposome doxorubicin + dexamethasone) regimens, but the benefits speed differed. The negative rate of flow minimal residual disease following induction, transplantation, and maintenance was 18.8% (54 cases) , 41.4% (109 cases) , and 58.7% (142 cases) , respectively. The median time to progress (TTP) was 78.7 months and the median overall survival (OS) was 109 months. The median TTP for RISS-Ⅰ-Ⅲ patients were 111.8 months, 77.4 months, and 30.6 months, and the median OS was 118.8 months, 91.4 months, and 48.5 months, respectively. At various points during treatment, the TTP and OS of patients obtaining CR and MRD negative were longer than those of patients who did not obtain CR and MRD negative. TTP was noticeably shorter in high-risk cytogenetic patients compared to standard-risk patients even when CR was acquired during induction. There was no difference in TTP between patients with high-risk cytogenetics and those with standard-risk cytogenetics if MRD negative was acquired during induction. According to a multivariate analysis, the R-ISS stage was a poor predictor of TTP and OS at various treatment intervals. Therapeutic effectiveness was a newly independent prognostic factor following treatment.Conclusion:A median survival of almost 10 years is possible for MM patients who receive an integrated strategy of induction regimens followed by auto-HSCT and maintenance therapy, which significantly improves prognosis. However, this approach did not significantly benefit high-risk cytogenetic MM patients.
