Objective:To establish the "1+3" management module of high-value consumables in Operation Room and verify its application, so as to provide new ideas for cost management of consumables in Operation Room.Methods:The Operating Room team of Shenzhen Hospital of Southern Medical University designed a "1+3" management module in 2022, where "1" referred to the management process of high-value consumables in Operation Room, and "3" referred to the precise management of consumables in Operation Room warehouse, the management of closed-loop use of Operation Room consumables and adverse event management of consumables. Surgeries using high-value consumables in the Thoracic Surgery Department, Gastrointestinal Surgery Department, and Urology Department of the hospital were selected as the research objects. The surgeries using conventional consumables from January to June 2022 were set as the control group, and the surgeries implementing the "1+3" management module from July to December 2022 were set as the observation group. The number of consumables received by the itinerant nurses before the operation and the number of high-value consumables returned after the operation were compared between the two groups. And the number of missed and error charges for high-value consumables in the two groups were counted and compared.Results:The number of consumables received before operation in the control group was higher than that in the observation group, and the difference was statistically significant ( P<0.05). The number of high-value consumables returned in the observation group was less than that in the control group, and the difference was statistically significant ( P<0.01). The proportion of missed charges for consumables in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.01), but there was no statistically significant difference in the proportion of incorrect charges between the two groups ( P>0.05) . Conclusions:The "1+3" management module for high-value consumables in Operation Room makes the process of receiving, returning, and charging high-value consumables clear, with traceable data, achieving refined management of high-value consumables in Operation Room, reducing the number of high-value consumables returned to the warehouse and reducing the proportion of missed consumables, which is conducive to effective cost control in Operation Room.

Purpose: This study identified risk factors for neurogenic lower urinary tract dysfunction (NLUTD) in patients with acute ischemic stroke (AIS) through multidimensional analysis of the medical records of patients, aiming to reduce the incidence of NLUTD, improve prognosis, and facilitate rehabilitation. Materials and Methods: In this case-control study, patients with AIS were recruited from two tertiary general hospitals in Shenzhen, China, from March 2021 to October 2023. Patients were divided into NLUTD and non-NLUTD groups based on the presence and absence of NLUTD, respectively. Comparative analysis was performed using the Mann–Whitney U and chi-square tests, with significant variables being included in logistic regression analysis. Results: Of the 652 participants enrolled in this study, 119 participants (18.3%) developed NLUTD. Bivariate analysis showed that 39 of 54 screened factors exhibited a significant correlation (p<0.05) with the incidence of NLUTD after AIS. Significant variables identified through logistic regression analysis included Glasgow coma scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) scores, anemia, aphasia, pneumonia, brainstem involvement, multiple lesions, urine clarity (CLA), random venous blood glucose (GLU) and hemoglobin (HGB) levels, and white blood cell (WBC) count. Conclusions A total of 11 risk factors for NLUTD were identified in this study. This finding provides valuable guidance for reducing the incidence of NLUTD after AIS and improving the quality of life of patients.

Objective:To investigate the clinical efficacy of liver transplantation for intra-hepatic cholangiocarcinoma.Methods:The retrospective cohort study was conducted. The clinico-pathological data of 22 patients with intrahepatic cholangiocarcinoma who underwent liver trans-plantation in the 5 medical centers, including First Hospital of Jilin University, et al, from September 2005 to December 2021 were collected. There were 18 males and 4 females, aged 57(range, 38?71)years. Observing indicators: (1) clinicopathological characteristics of patients with intrahepatic cholangiocarcinoma; (2) follow-up; (3) prognosis. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages. The Kaplan-Meier method was used to draw survival curves. The Log-Rank test was used for survival analysis. Results:(1) Clinicopathological characteristics of patients with intrahepatic cholangio-carcinoma. Of the 22 patients, 20 cases were diagnosed as intrahepatic cholangiocarcinoma before liver transplantation, 7 cases had viral hepatitis type B, 1 case had primary sclerosing cholangitis, 7 cases had tumor treatment before liver transplantation, 7 cases, 6 cases and 9 cases were classified as grade A, grade B and grade C of the Child-Pugh classification, 16 cases had preoperative CA19-9 >40 U/mL, 14 cases had single tumor, 11 cases with tumor located at right lobe of liver, 6 cases with tumor located at both left and right lobe of liver, 5 cases with tumor located at left lobe of liver, 9 cases with tumor vascular invasion. All 22 patients were diagnosed as moderate-poor differentiated tumor. There were 9 cases with liver cirrhosis, 4 cases with tumor lymph node metastasis, 10 cases with tumor burden within Milan criteria. The tumor diameter of 22 patients was 4.5(range, 1.5?8.0)cm. (2) Follow-up. All 22 patients were followed up for 15(range, 3?207)months. Of the 22 patients, 9 cases had tumor recurrence and 8 cases died. (3) Prognosis. The 1-year overall survival rate and 1-year disease-free survival rate of the 22 patients was 72.73% and 68.18%, respectively. Results of subgroup analysis showed there were significant differences in overall survival and disease-free survival between the 10 patients with tumor burden within Milan criteria and the 12 patients with tumor burden beyond Milan criteria who underwent liver transplantation ( hazard ratio=0.13, 0.26, 95% confidence interval as 0.03?0.53, 0.08?0.82, P<0.05). Results of further analysis of the 12 patients with tumor burden beyond Milan criteria showed there were significant differences in overall survival and disease-free survival between the 5 patients with preoperative tumor down-staging treatment and the 7 patients without preoperative tumor down-staging treatment ( hazard ratio=0.18, 0.14, 95% confidence interval as 0.04?0.76, 0.04?0.58, P<0.05). Conclusions:Intrahepatic cholangiocarcinoma patients with tumor burden within Milan criteria have a better prognosis than patients with tumor burden beyond Milan criteria after liver transplantation. For patients with tumor burden beyond Milan criteria, active tumor down-staging treatment before liver transplantation can improve the prognosis.

Objective:To screen plasma exosomal protein molecular markers in patients with spinal cord injury (SCI) by applying Label-Free quantification and bioinformatics analysis.Methods:Fifty plasma specimens from the First Affiliated Hospital of Nanjing Medical University (from January 2021 to June 2022) were collected from SCI patients and healthy people, respectively. Plasma exosomes were isolated using ultracentrifugation and identified by transmission electron microscopy, nanoparticle tracking analysis and western blot. Plasma exosomal differentially expressed proteins (DEPs) were analyzed using Label-Free quantitative proteomics, and DEPs were characterized, annotated, and enriched based on Gene Ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) databases. The screened DEPs were validated by western blot and enzyme linked immunosorbent assay (ELISA) using plasma exosomal specimens.Results:According to the spinal cord injury classification of the American Spinal Injury Association, 14 cases were grade A, 19 cases were grade B, 12 cases were grade C, and 5 cases were grade D. Plasma exosomes of SCI patients and control groups showed typical cup-like morphology, with diameters mainly ranging from 30-200 nm. A total of 493 exosomal proteins were identified by Label-Free quantification, and 126 proteins were screened for differential expression, of which 38 were up-regulated and 88 were down-regulated. GO annotation revealed that DEPs were mainly involved in functions such as protein activation cascade, complement activation and immune response. KEGG pathway analysis revealed that DEPs were involved in biological pathways such as complement and coagulation cascade reactions, proteasome and neurodegenerative disease pathways. Two candidate proteins, APOB and S100A9, were initially screened based on quantitative results from proteomics and bioinformatics analyses. Western blot results showed that the relative expression of S100A9 protein in plasma exosomes of 30 SCI patients (1.62±0.19) was elevated compared with that of 30 control groups (0.86±0.24), and the difference was statistically significant ( t=8.55, P<0.001), while the relative expression of APOB protein (1.06±0.13 and 1.02±0.23) were not statistically significant ( t=0.46, P=0.653). The results of ELISA analysis showed that the expression of S100A9 in plasma exosomes of patients with different degrees of SCI (grade A 197.7±11.7 pg/ml, grade B 151.7±15.2 pg/ml, grade C 136.3±14.7 pg/ml) had statistical significance ( F=69.94, P<0.001), the higher the severity of SCI, the higher the expression of S100A9 in plasma exosomes (A vs. B, q=13.11, P<0.001; A vs. C, q=15.66, P<0.001; B vs. C, q=4.19, P=0.005). Conclusion:S100A9 is a potentially valid plasma exosomal molecular marker for assessing the severity of SCI.

Objective:To construct a combined diet and exercise program for puerperal women with Yin-deficiency constitution based on traditional Chinese medicine (TCM) constitution identification, and evaluate the effect of this program.Methods:This study was guided by the complex intervention development framework of the UK Research Council, and based on the TCM constitution identification, and determined the combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification through literature review, case analysis, group discussion, and Delphi method. From October to December 2022, convenience sampling was used to select 76 delivery women with Yin-deficiency constitution who delivered at Shenzhen Hospital of Southern Medical University as the research subject. According to the delivery time, the delivery women were divided into a control group ( n=37) and an experimental group ( n=39). The control group adopted routine postpartum nursing. On this basis, the experimental group implemented the combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification. We compared the Yin-deficiency constitution score, duration of lochia, and incidence of puerperium complications between two groups of delivery women before and after intervention. Results:The final constructed program included 6 primary indicators, 20 secondary indicators, and 50 tertiary indicators. In the two rounds of consultation, the positivity coefficients of experts were all 100%, the authority coefficients of experts were 0.827 and 0.843, and the Kendall harmony coefficients were 0.419 and 0.502, respectively with a statistical difference ( P<0.01). After intervention, the score of Yin-deficiency constitution, duration of lochia, and incidence of puerperium complications in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification is scientific, comprehensive, and feasible, which can provide reference for future development of TCM constitution management during the puerperium.

Objective:To understand the attitude, practice status and influencing factors of obstetric medical staff on sexual health care during pregnancy, and to provide reference for carrying out sexual education and training during pregnancy.Methods:A self-designed questionnaire on attitude and practice of obstetric medical staff towards sexual health care during pregnancy was used to investigate 462 obstetric medical staff in Guangdong Province from July to August, 2021,and the influencing factors were analyzed.Results:The attitude score of sexual health care during pregnancy among obstetric medical staff was (29.87 ± 5.96) points, and the practice score was (13.61 ± 1.23) points. Profession and hospital level affected obstetric medical staff′s attitude towards sexual health care during pregnancy ( P<0.05); profession, title and hospital level affected obstetric medical staff′s practice in providing pregnancy sexual health care ( P<0.05). Conclusions:Obstetric medical staff have a negative attitude towards sexual health care during pregnancy, and their active sexual health care behaviors need to be improved. Medical schools and work units need to strengthen the training and management of obstetric-related and reproductive health knowledge and skills to promote the effectiveness of pregnancy sexual education implementation and promotion.

Objective:To investigate the regulatory effects of nuclear factor-κB (NF-κB) on dendritic cell (DC) maturation and function through solute carrier family 1 member 2 (Slc1a2).Methods:Mouse bone marrow-derived DCs were transfected with Slc1a2-specific siRNA and an overexpression Slc1a2 eukaryotic expression vector. The real-time fluorescence quantitation (RT-PCR) and Western Blot methods were used to detect knockdown and overexpression efficiency. The expression of surface molecules (CD40, CD80) and major histocompatibility complex Ⅱ (MHCⅡ) of DCs was detected by flow cytometry. ELISA was used to detect the secretion of the cytokines interleukin (IL)-12, IL-6, and transforming growth factor-β (TGF-β). The effects of knockdown of Slc1a2 on DC maturation and function and the effects of overexpression of Slc1a2 on DC maturation and function were reflected by the above assay results. A mixed lymphocyte culture assay was used to investigate the effect of Slc1a2 on T cell proliferation, and an ELISA was used to detect the lavel of IL-17A. Changes in the relative fluorescence intensity of FITC in DCs were analyzed by flow cytometry to investigate the ability of Slc1a2 overexpression on antigen phagocytosis. Finally, DCs were pretreated with an NF-κB inhibitor, toluoylphenylalanine chloromethyl ketone (TPCK), and the effect of TPCK on the expression of Slc1a2 in DCs and DC maturation was examined.Results:Slc1a2 expression was found to be high in DC treated with lipopolysaccharides (LPS) ( P<0.001). The knockdown of Slc1a2 decreased DC maturation and ability to stimulate the proliferation of CD4 + T cells ( P<0.001) and inhibited IL-17 secretion ( P<0.01). Overexpression of Slc1a2 promoted DC maturation and ability to stimulate the proliferation of CD4 + T cells(all P<0.01) Pretreatment of DC with the NF-κB inhibitor TPCK inhibited the expression of Slc1a2 at mRNA and protein levels induced by LPS. Conclusions:NF-κB regulates Slc1a2 expression, which affects the maturation and function of DC.

The goal of the study was to investigate the protective effect and mechanism of Artemisia argyi ethanol extract on chemotherapeutic vancomycin (VAN)-induced acute kidney injury (AKI).The acute kidney injury model of male ICR mice was induced by intraperitoneal injection (ip) of VAN.Thirty mice were divided into the blank group, model group, high dose group, middle dose group and low dose group, which were given medicine by gastric perfusion (ig).Serum levels of cystain C (Cys C), blood urea nitrogen (BUN) and serum creatinine (Scr) were measured, which could reflect renal function of mice.Serum oxidative stress and inflammation indices were also determined, including muscular dystrophy association (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), tumor necrosis factor-alpha (TNF-α), Interleukin-1β (IL-1β), and high-sensitive c-reactive protein (hs-CRP).In addition, hematoxylin-eosin staining (HE) was employed for measuring the damage of renal tissues and the content of apoptosis b-cell lymphoma-2 (Bcl-2), Bcl-2 assaciated X protein (Bax) and caspase-3 were measured too.All results showed that Artemisia argyi extract exhibits protective effect on chemotherapeutic VAN-induced AKI, whose mechanism could be related to the oxidative stress, inflammatory reaction and apoptosis.
