Objective: To investigate the effects of "liver-smoothing and spirit-regulating" acupuncture on the intestinal flora, lipopolysaccharide (LPS) and the hippocampal toll-like receptor 4 (TLR4)/ transcription factor (NF)-κB signaling pathway in depressive disorder mouse model, and to explore its underlying mechanisms. Methods: Eighteen male SPF-grade C57BL/6J mice were randomly assigned to the control, model, and acupuncture groups using a random number method, with six mice in each group. The depression disorder model was induced in mice from both the acupuncture and model groups using CUMS. The mice in the acupuncture group were treated with acupuncture at the acupoints of "Baihui" (DU20), "Yintang" (DU29), "Hegu" (LI4), and "Taichong" (LR3) on the 15th day of modeling, with a duration of 20 min per session, once per day, for 2 consecutive weeks. Behavioral differences were assessed using the sucrose preference test, open field test, and forced swim test. Hematoxylin-eosin staining was used to observe pathological changes in the hippocampus and colon. The levels of the inflammatory factors interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and LPS in the hippocampus and colon were measured using Enzyme-linked Immunosorbent Assay. Western blotting was used to detect the expression of TLR4 and NF-κB protein in the hippocampus. Changes in gut microbiota structure and abundance were analyzed by 16 S rDNA sequencing. Results: Compared to the control group, the model group showed reduced sucrose preference rate, time in the center area, and total distance, with an increase in immobility time (P<0.01). Inflammatory pathological changes were observed in the hippocampal CA1 region and colon. The contents of IL-1β, IL-6, TNF-α, and LPS in the hippocampus and colon increased (P<0.01). The protein expression levels of hippocampal TLR4 and NF-κB were increased (P<0.01). The Chao1 index was increased (P<0.01). The relative abundances of Pseudomonadales, Acinetobacter, Moraxellaceae, Solibacillus, Escherichia_shigella, Enterobacteriaceae, Enterobacterales, Dubosiella, and Erysipelottichales were decreased, while the relative abundances of Alloprevotella and gram_negative_bacteriurh_cTPY_13 were increased (P<0.05). The pathways of lipopolysaccharide biosynthesis and pathogenic Escherichia coli infection were upregulated, and the pathway of terpenoid backbone biosynthesis was downregulated (P<0.01). Compared to the model group, the acupuncture group showed increased sucrose preference, time in the center area, and total distance, with a decrease in immobility time (P<0.01). The inflammatory pathological changes in the hippocampal CA1 region and colon were alleviated. The contents of IL-1β, IL-6, TNF-α, and LPS in the hippocampus and colon were reduced(P<0.01). The protein expression levels of hippocampal TLR4 and NF-κB were reduced (P<0.01). The Chao1 index was decreased (P<0.05), and the relative abundances of Dubosiella and Erysipelotrichaceae were increased, while the relative abundance of Rikenellaceae, Alloprevotella, and gram_negative_bacteriuch_cTPY_13 were decreased(P<0.05). The pathways of lipopolysaccharide biosynthesis and pathogenic Escherichia coli infection were significantly downregulated, and the pathway of terpenoid backbone biosynthesis was upregulated (P<0.01). Conclusion " Liver-smoothing and spirit-regulating" acupuncture can improve depressive symptoms in depressive disorder mice, potentially through regulating the LPS and TLR4/NF-κB signaling pathway mediated by intestinal flora, reducing the inflammatory response of the hippocampus, and improving the pathological injury of the hippocampus.

Objective:To explore the effects of metformin on levels of peripheral blood regulatory T cells (Treg)/Th17 cells and related cytokines in patients with type 2 diabetes mellitus (T2DM) and influenza A.Methods:A total of 108 patients with T2DM and influenza A treated in Zhejiang Veteran Hospital were prospectively enrolled between April 2021 to April 2022. According to different medication methods, they were divided into observation group (54 cases, oseltamivir + metformin) and control group (54 cases, oseltamivir + gliclazide). The average usage time and dosage of oseltamivir, concentration of blood lactate and blood gas level, counts of Th17 and Treg cells, and levels of related cytokines in the two groups were compared before and after treatment.Results:The average usage time and dosage of oseltamivir, and concentration of blood lactate were higher in observation group than control group: (8.94 ± 0.88) d vs. (7.23 ± 0.79) d, (1.32 ± 0.15) g vs. (1.08 ± 0.11) g, (1.83 ± 0.43) mmol/L vs. (1.61 ± 0.32) mmol/L, P<0.05. The differences in pH, partial pressure of arterial oxygen (PaO 2) and partial pressure of arterial carbon dioxide (PaCO 2) between the two groups had no statistically significant before and after treatment ( P>0.05). After treatment, the differences in count of Treg cells, interleukin-10 (IL-10), interleukin-4 (IL-4), CD 3+, CD 4+ and CD 4+/CD 8+ between the observation group and the control group were statistically significant: (35.48 ± 5.64)% vs. (42.53 ± 6.17)%, (30.49 ± 4.72) ng/L vs. (35.64 ± 5.08) ng/L, (32.15 ± 3.06) ng/L vs. (35.33 ± 3.12) ng/L, (61.39 ± 3.28) % vs. (66.27 ± 3.05)%, (34.12 ± 1.93)% vs. (36.59 ± 2.61)%, 1.26 ± 0.34 vs. 1.52 ± 0.41, P<0.05. After treatment, the count of Th17 cells, Th17/Treg, interleukin-17 (IL-17) and γ-interferon (IFN-γ) in the observation group were higher than those in the control group:(8.69 ± 1.42)% vs. (7.94 ± 2.03)%, 0.24 ± 0.06 vs. 0.19 ± 0.05, (17.67 ± 3.11) ng/L vs. (12.18 ± 3.42) ng/L, (287.48 ± 45.12) ng/L vs. (254.27 ± 41.09) ng/L, P<0.05. During treatment, the difference in incidences of adverse reactions between the two groups had no statistically significant ( P>0.05). Conclusions:Oseltamivir combined with metformin can recover the balance of Th17/Treg cells in patients with T2DM and influenza A to a certain extent. Clinically, level of blood lactate should be monitored.

【Objective】 To investigate the detection of pathogenic microorganisms in umbilical cord blood and maternal blood from 2012 to 2021, so as to improve the collection of umbilical cord blood and guarantee the safety of umbilical cord blood hematopoietic stem cells (HSC) . 【Methods】 Detection results of pathogenic microorganisms of umbilical cord blood and maternal blood among 64 077 cases from Tianjin Cord Blood Bank from 2012 to 2021 were retrospectively analyzed. 【Results】 A total of, 2 072 cases (3.23%) were detected positive, among which, 184 cases (0.29%) were positive for aerobic bacteria culture, 1 504 cases (2.34%) were positive for anaerobic bacteria culture, and 384 cases (0.60%) were positive for both aerobic and anaerobic bacteria culture. From 2012 to 2021,the overall positive rate showed a downward trend, with a difference in the positive rate between each year (P<0.05). The positive rate of anaerobic bacteria was higher than that of aerobic bacteria and that of anaerobic and aerobic bacteria (P<0.05). After Gram staining, the microscopic detection rate of bacterial positive samples was highest in G^- bacilli, followed by G⁺ bacilli, G⁺ cocci, G^- cocci and others. Among the 64 077 cases, 169 cases (0.26%) showed reactivity in cord blood tests and 1 231 cases (1.92%) showed reactivity in maternal blood tests. Umbilical cord blood and maternal blood HIV-Ag/Ab tests showed reactivity after initial screening. After confirmation by Western blotting, there was 1 case of uncertain maternal blood, while the rest were negative. The reactive rates of anti-TP (0.12%) and anti- HCV (0.11%) in umbilical cord blood were higher than those of HBsAg (0.03%) and CMV-IgM (1/64 077).There was a difference in the reactive rate of anti-TP detection in umbilical cord blood between different years (P<0.05),while there was no statistically significant difference in that of HBsAg, anti-HCV and CMV-IgM (P> 0.05).The reactive rate of HBsAg in maternal blood (1.38%) was higher than that of CMV-IgM(0.29%) , anti-TP(0.13%) and anti-HCV (0.12%) . There were differences in the reactive rates of HBsAg, anti-HCV ,and anti-TP in maternal blood among different years (P<0.05),and that of HBsAg showed a decreasing trend, while the reactive rate of CMV-IgM was not statistically significant (P>0.05). The reactive rates of HBsAg and CMV-IgM detected in maternal blood were significantly higher than those in umbilical cord blood (P<0.05) . The reactive rates of anti-HCV and anti-TP in maternal blood were consistent with those in umbilical cord blood (P>0.05). 【Conclusion】 The reactive rates of anti-HIV and CMV-IgM in cord blood, and that of anti-HIV in maternal blood are low, but those of anti-TP and anti-HCV in cord blood are relatively high. The reactive rate of HBsAg is high in maternal blood,but with a downward trend,but low in umbilical cord blood due to maternal-infantile transmission blocking. The detection of transfusion transmitted pathogens and bacteria plays a critical role on the safety of umbilical cord blood HSCs. Effective detection of transfusion transmitted pathogens and culture of bacteria are the key to ensure the quality of umbilical cord blood, which can improve the safety of umbilical cord blood HSCs transplantation.

Background::High-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori ( H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI–amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment. Methods::This was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance. Results::A total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (–9.19% in the ITT analysis, –9.21% in the MITT analysis, and –9.73% in the PP analysis) was greater than the predefined non-inferiority margin of –10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients’ compliance were similar between the two groups. Conclusions::Fourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region. Trial registration::Clinicaltrials.gov, NCT04678492.

Objective To explore the effects of application and management of the standardized training system for newly graduated registered nurses. Methods A total of 238 newly graduated nurses in Peking University First Hospital were selected by purposive sampling method. The 138 nurses who were enrolled in August 2015 were assigned into control group, adopting the traditional training program for new nurses. The 100 newly enrolled nurses in August 2016 were assigned into observation group, adopting the new standardized training program for new nurses. After training, the nurses of both groups were evaluated with the Transition Shock of Newly Graduated Nurses Scale (TSNGNS), the New Nurse Standardized Training Satisfaction Questionnaire, and the comprehensive examination paper. Results The total scores of TSNGNS, physical dimension, psychological dimension, social culture and development of nurses in the observation group were lower than those in the control group after training, and the differences were statistically significant (P＜0.01). After training, the total score and each dimension score of nurse satisfaction questionnaire in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). After the training, the comprehensive examination score of the nurses in the observation group was higher than that in the control group, and the difference was statistically significant (P＜ 0.01). Conclusions The implementation of the new training scheme can effectively relieve the new nurses' transition shock and improve their satisfaction and comprehensive evaluation score during training.
