OBJECTIVE: To explore the role of antibiotic-eluting absorbable calcium sulfate in treating periprosthetic infection after one-stage revision of knee arthroplasty. METHODS: A retrospective analysis was performed on 36 patients(36 knees)who underwent phaseⅠrevision for periprosthesis infection after total knee arthroplasty from January 2018 to March 2022. All patients were underwent knee cavity puncture before operation and had positive results of aseptic body fluid culture, 21 patients received revision combined with antibiotic loaded calcium sulfate at stageⅠ(calcium sulfate group) during operation, and 15 patients underwent renovation at stageⅠ(revision group). There were 9 males and 12 females in calcium sulfate group, aged from 54 to 76 years old with an average of(67.6±6.2) years old. There were 15 patients in revision group, including 4 males and 11 females, aged from 60 to 75 years old with average of (69.6±4.1) years old. The levels of serum C-reactive protein (CRP), interleukin-6 (IL-6) at 7, 14, 30 and 90 days after operation were compared between two groups, and the rate of end-infection control at follow-up were compared. The systemic antibiotic application time, hospital stay and postoperative complications were observed between two groups. RESULTS: Calcium sulfate group were followed up for 12 to 29 months with an average of(18.9±4.2) months, and the infection control rate was 90.5%;while revision group were followed up 18 to 29 months with average of (21.6±3.7) months, and the infection control rate was 86.7% (13/15). There were no significant differences in follow-up time and infection control rate between two groups(P>0.05). Postoperative levels of CRP and IL-6 at 7, 14 and 30 days in calcium sulfate group were (32.79±11.48), (15.50±6.52), (9.36±3.32) mg·L^-1 and (17.31±6.15) pg·ml^-1, respectively;which were lower than those in revision group (40.65±11.32), (30.15±10.57), (18.97±5.86) mg·L^-1 and (25.54±6.73) pg·ml^-1, had statistical differences(P<0.05). There were no significant differences in IL-6 levels at 7 and 14 days after operation and CRP levels at 90 days after operation between two groups (P>0.05). The hospitalization time and systemic antibiotic application time in calcium sulfate group were (18.4±2.2) and (63.5±21.4) d, respectively;which were better than those in revision group (20.5±2.4) and (82.7±16.9) d, and had statistical differences(P<0.05). No significant wound complications and hypercalcemia were observed in calcium sulfate group. CONCLUSION Antibiotic eluted absorbable calcium sulfate could be used to treat periprosthetic knee infection, significantly reducing CRP levels in the early postoperative period, shortening hospital stay and systemic antibiotic application time, but it does not significantly improve the control rate of revision infection at stageⅠ.

Objective:To evaluate the effect of nursing specialist nurses′ assistance on the ability of nursing home nurses to maintain venous catheter under the vision of combination of medical care and nursing care, providing reference for carrying out specialized nursing assistance work in grassroots hospitals.Methods:This study was an experimental study. According to Miller′s pyramid theory, a model of specialist nurse assistance was established with specialized technology as the core. From January to December 2021, three nursing hospitals in Suzhou were assisted. Convenience sampling method was used to investigate the ability of intravenous catheter maintenance, the incidence of central venous catheter maintenance defects, the incidence of central venous catheter complications and unplanned extubation, and the satisfaction of doctors and patients before and after help.Results:Totally 86 nurses were included, aged (33.17 ± 2.31) years old. After the help, the theoretical and operational skill scores of nurses in the nursing home were (89.77 ± 2.11) and (92.75 ± 1.62) points, respectively, which were significantly higher than those before the help (60.84 ± 2.71) and (79.81 ± 1.68) points, and the differences were statistically significant ( t=-84.96, -52.12, both P<0.05). Among the maintenance defects of central venous catheter in nursing homes, incomplete labeling, film wrapping, blood seepage, catheter discounting, non-standard film fixing, and incomplete information of extended care were 9.95% (21/211), 8.53% (18/211), 2.84% (6/211), 6.16% (13/211), 4.74% (10/211), 2.37% (5/211) after help, all lower than 50.57% (89/176), 43.18% (76/176), 14.20% (25/176), 25.57% (45/176), 18.18% (32/176), 11.93% (21/176) before help. The differences were statistically significant ( χ2 values were 14.00 to 77.81, all P<0.05). The incidence of medical adhesive related skin injury, catheter obstruction complications and unplanned extubation were 4.44% (4/90), 3.33% (3/90) and 2.22% (2/90), respectively, which were lower than 20.51% (16/78), 15.38% (12/78) and 11.54% (9/78) before help. The differences were statistically significant ( χ2=8.81, 6.06, 4.50, all P<0.05). Doctors′ satisfaction with nurses and patients′ satisfaction with nursing work were 96.43%(27/28) and 93.75%(45/48), respectively, both higher than 71.43%(20/28) and 72.73%(32/44) before help, and the differences were statistically significant respectively ( χ2=4.77, 5.97, both P<0.05). Conclusions:From the perspective of combination of medical care and nursing care, the maintenance and assistance of intravenous catheters by the team of intravenous therapy nurses in nursing hospitals can effectively reduce the incidence of central venous catheter complications and unplanned extubation, improve the maintenance ability of intravenous catheters of nurses in nursing hospitals, and help to improve the quality of nursing care in nursing hospitals.

This paper applied gas chromatography-mass spectrometry (GC-MS), network pharmacology and nuclear magnetic resonance hydrogen spectroscopy (¹H NMR) metabolomics techniques to study the material basis and mechanism of action of Ning Shen Essential Oil in anti-insomnia. The main volatile components of Ning Shen Essential Oil were analyzed by gas chromatography-mass spectrometry (GC-MS), and the insomnia-related targets were predicted using the Traditional Chinese Medicine Systematic Pharmacology Database and Analytical Platform (TCMSP) and the databases of GeneCards, OMIM and Drugbank. The insomnia model of rats was replicated by intraperitoneal injection of 4-chloro-DL-phenylalanine (PCPA). Animal experiments were approved by the Animal Ethics Committee of Shandong University of Traditional Chinese Medicine (Ethics No.: SDUTCM20221025010). The modulating effect of Compound Ning Shen Essential Oil on anxiety behavior of rats was evaluated by behavioral related indexes. The serum levels of corticotropin-releasing hormone (CRH), adrenotropic corticotropic hormone (ACTH) and melatonin (MT) were measured by enzyme-linked immunoassay (ELISA). Rat serum and hippocampus were taken for nuclear magnetic resonance (¹H NMR) metabolomics to detect the changes of endogenous metabolites in rat serum hippocampus, to designate the differential metabolites and to construct metabolic pathways. The results showed that the exercise distance in the open field experiment and the number of times and time to enter the open arm in the elevated cross maze experiment of the rats in the model group were significantly reduced (P < 0.05, P < 0.01). The behavioral indexes of rats improved to different degrees after the administration of Ning Shen Essential Oil. The serum CRH and ACTH levels of rats in the model group increased significantly (P < 0.05, P < 0.01), and the MT level decreased significantly (P < 0.01); After the intervention, serum CRH and ACTH levels were reduced to different degrees, and MT levels could be regressed. ¹H NMR metabolomics screened 10 potential biomarkers related to insomnia, which involved in 6 potential metabolic pathways. A total of 35 components of Ning Shen Essential Oil were detected by GC-MS, the main component targets of Ning Shen Essential Oil and insomnia disease targets were intersected, a total of 172 intersecting genes were screened, and 26 core targets were identified. The study demonstrated that Ning Shen Essential Oil had protective effects against PCPA-induced insomnia in rats, which was probably correlated with regulation of the hypothalamic-pituitary-adrenal axis (HPA) related hormones and metabolism of amino acids, lipids and choline.

Catheter related blood stream infection (CRBSI), a common complication in the department of critical care medicine, may result in longer stay in the department of critical care medicine, increased hospitalization costs, even sepsis that leads to increased mortality in severe patients. The infection control of CRBSI has become the focus of the department of critical care medicine and even hospital management as well as the core of quality control. At present, the prevention program of CRBSI in the department of critical care medicine has been basically in place, and the national standards for infection prevention during central venous catheter placement and maintenance have been established. The establishment and implementation of these norms can effectively reduce the incidence of CRBSI, but CRBSI in the department of critical care medicine is still common and serious, indicating that there are defects in the aseptic operation during central vein catheterization and use. The corre- sponding operation process should be investigated and improved, and efforts should be made from the aspects of theory, management, education, norms, and supervision to avoid or reduce the occurrence of CRBSI and even achieve zero infection by improving and implementing various sensory control requirements in clinical operation.

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.
