OBJECTIVE: To preliminarily investigate the effect of buccal acupuncture therapy on ameliorating postoperative pain and enhancing recovery quality among patients undergoing radical resection of gastrointestinal cancers. METHODS: Fifty-two participants were randomized at a 1:1 ratio to either the buccal acupuncture or the control group. The acupuncture protocol entailed targeting 5 predetermined acupoints [CA-2 (Upper jiao), CA-3 (Middle jiao), CA-4 (Lower jiao), CA-6 (back), and CA-7 (waist) and two adjustable acupoints [CA-1 (head) and CA-8 (sacrum)] on each side of the face. The outcomes included the Numeric Rating Scale (NRS) scores for each day within 7 days postoperatively, 15-Item Quality of Recovery Scale (QoR-15) scores, analgesics consumption during and after surgery, incidences of postoperative nausea and vomiting, and perioperative levels of interleukin-6 and glucose. Adverse events related to acupuncture were recorded. RESULTS: Of the initial 52 participants, 46 completed the study and were included in the analysis. Findings indicated that the buccal acupuncture group experienced significantly reduced resting NRS scores in post-anesthesia care unit and throughout the postoperative phase (P=0.001 and P=0.003, respectively), along with enhanced QoR-15 scores on the 3rd postoperative day (P=0.008), compared to the control group. No notable differences were identified in the remaining indicators (P>0.05). CONCLUSION Buccal acupuncture therapy demonstrated significant effectiveness in reducing postoperative pain and improving recovery quality for patients undergoing radical resection of gastrointestinal cancers, presenting a viable intervention without associated adverse outcomes.

Objective To investigate the benefits of using a stapler tractor in the treatment of segmental bronchus during lung segmentectomy through detailed video replay analysis of surgical procedures. Methods We collected data from patients who underwent segmentectomy performed by the same surgical team in the Department of Thoracic Surgery, the First Affiliated Hospital of Nanjing Medical University, from November 2020 to August 2023. After excluding data that lacked analysis parameters, the remaining patients were divided into four groups based on the methods used for dissociating segmental bronchus: a stapler tractor group (group A), a stapler with bronchial stretching group (group B), a stapler only group (group C), and a silk ligature group (group D). Then, we compared baseline data and videotaped surgical details across all groups. Surgical details included the success rate of one-time segmental bronchus dissociation and severance, the time taken for successful one-time dissociation and severance of the segmental bronchus, the incidence of bleeding during bronchus dissociation, the conversion rate to thoracotomy during surgery, and surgical outcomes such as total operative time, postoperative hospitalization days, postoperative thoracic drainage volume, and pulmonary air leakage rate. Results The study included 325 patients (203 in the group A, 62 in the group B, 29 in the group C, and 31 in the group D). There was no statistically significant difference in baseline data among the four groups. However, significant differences were found in terms of total operation time, postoperative hospitalization days, intraoperative blood loss, segmental bronchial stump length, postoperative air leakage rate, hemorrhage rate during segmental bronchial dissociation, and conversion to thoracotomy rate among the four groups (P<0.05). Conclusion Using a stapler tractor for dissociating segmental bronchus in lung segmentectomy results in shorter operative time, less risk of intraoperative bleeding, and less surgical complications. This study provides valuable evaluation methodologies through the analysis of video replay surgical details, contributing to the improvement of lung segmentectomy quality.

Targeted radiation therapy using radionuclides is a favored approach for treating tumors.This procedure involves the delivery of drugs to the lesion site via carriers or interventional methods,followed by the emission of radiation energy that selectively irradiates the lesion tissue.This approach minimizes damage to normal tissue and achieves the desired therapeutic effect.Factors such as the type of therapeutic radionuclide,radiation energy,physical half-life,method of preparation,and toxicity determine their clinical application.In this paper,the characteristics and clinical application of therapeutic radionuclides were reviewed to providing reference for the clinical application of targeted therapeutic radionuclides.

Radiopharmaceuticals play an important role in the medical field,but they also carry certion risks and potential safety concerns.Medical institutions implement pharmacovigilance to ensure the safety of patients'drug use,including the safety of Radiopharmaceuticals.The operation and management of the pharmacovigilance system in the United States and the European Union are relatively mature.China can learn from their advanced concepts and establish our own radiopharmaciligence system.

Abstract: Objective To investigate the clinical distribution characteristics, drug resistance trends and the carrying of antiseptic resistance gene of Pseudomonas aeruginosa infection in children in Suzhou, in order to provide theoretical basis for the prevention and treatment of Pseudomonas aeruginosa infection in children. Methods The clinical distribution characteristics and drug resistance trends of Pseudomonas aeruginosa isolated from Children's Hospital of Soochow University from 2016 to 2021 were retrospectively analyzed. Forthermore, 101 strains of Pseudomonas aeruginosa were randomly selected to detect the expression of 9 antiseptic resistance genes (qacEΔ1-sul1, qacE, qacEΔ1, qacG, sugE(p), sugE©, emrE, ydgE, ydgF) by polymerase chain reaction. Results Pseudomonas aeruginosa in Soochow University Children's Hospital was mainly isolated from respiratory specimen (47.83%), pus (28.60%) and urine (11.72%); the main departments were intensive care unit(21.45%), general surgery department (15.71%) and respiratory department (12.31%). Patients were mainly aged from 1 month to 1 year old and older than 6 years old (34.31% and 25.38%). The top three drug resistance rates of Pseudomonas aeruginosa were imipenem (11.25%), aztreonam (9.26%) and meropenem (8.02%). Among the 853 strains of Pseudomonas aeruginosa, the drug-resistant strains were mainly from the intensive care unit (58/183), hematology department (33/91), neonatology department (31/96), and there were 57 strains of multi-drug-resistant strains with the detection rate of 6.68%. There were 98 strains (11.49%) of Carbapenem resistant Pseudomonas aeruginosa, and the annual detection rates were 22.06%, 8.40%, 3.60%, 5.67%, 9.85% and 17.20%, respectively. Among the 9 antiseptic resistance genes, the carrying rate of ydgF, sugE© and qacE was 98.02%, 94.06% and 0 respectively. Conclusion Pseudomonas aeruginosa has high resistance to some drugs, so attention should be paid to rational drug use. The carriage rates of of two antiseptic resistance genes exceeded 90%, indicating the need to strengthen research on the mechanism of antiseptic resistance research and rational use of disinfectants

Background and Objectives: Chronic obstructive pulmonary disease (COPD) is a common, frequently-occurring disease and poses a major health concern. Unfortunately, there is current no effective treatment for COPD, particularly emphysema. Recently, experimental treatment of COPD using mesenchymal stem cells (MSCs) mainly focused on bone marrow-derived MSCs (BM-MSCs). Human umbilical cord-derived MSCs (hUC-MSCs) have more advantages compared to BM-MSCs. However, studies on the role of hUC-MSCs in management of COPD are limited. This study sought to explore the role of hUC-MSCs and its action mechanisms in a rat model of VEGF receptor blocker SU5416-injured emphysema. Methods: and Results: hUC-MSCs were characterized by immunophenotype and differentiation analysis. Rats were div-ided into four groups: Control, Control＋MSC, SU5416 and SU5416＋MSC. Rats in model group were administered with SU5416 for three weeks. At the end of the second week after SU5416 administration, model group were infused with 3×106 hUC-MSCs through tail vein. After 14 days from hUC-MSCs transplantation, rats were euthanized and data were analyzed. HE staining and mean linear intercepts showed that SU5416-treated rats exhibited typical emphysema while emphysematous changes in model rats after hUC-MSCs transplantation disappeared completely and were restored to normal phenotype. Furthermore, hUC-MSCs inhibited apoptosis as shown by TUNEL and Western blotting.ELISA and Western blotting showed hUC-MSCs rescued VEGF-VEGFR2-AKT pathway in emphysematous lungs. Conclusions The findings show that hUC-MSCs effectively repair the emphysema injury. This study provides the first evidence that hUC-MSCs inhibit apoptosis via rescuing VEGF- VEGFR2-AKT pathway in a rat model of emphysema.

OBJECTIVE: To investigate the expression level and prognostic value of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes in patients with multiple myeloma (MM). METHODS: Serum exosomes were extracted from 57 MM patients and 20 healthy persons using ExoQuick exosome precipitation solution kit, and the relative expression level of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes was measured by RT-qPCR. Correlations of the expression levels of all miRNAs mentioned above with routine laboratory parameters were analyzed by Spearman correlation analysis. The relationship between the expression level of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes and overall survival of patients with MM was analyzed using the Kaplan-Meier survival curve. RESULTS: The expression levels of miR-21, miR-18a, and Let-7b derived from serum exosomes in patients with MM were significantly lower than those in the normal control group (P<0.001), while the expression level of miR-146a between the two groups was not significantly different (P>0.05). The expression level of miR-21 was strongly negatively correlated with serum β₂-microglobulin concentration (r=-0.830), and weakly negatively correlated with serum creatinine, corrected serum calcium, and cystatin C (r=-0.488, -0.282, -0.627). The expression levels of Let-7b and miR-18a were also weakly negatively correlated with the corrected serum calcium, β₂-microglobulin, and cystatin C concentration (r=-0.305, -0.362, -0.461; -0.317, -0.542, -0.434). However, there was no significant correlation between the expression level of miR-146a and routine laboratory parameters in MM patients. The overall survival rate of MM patients with low expression level of miR-21, miR-18a, and Let-7b significantly decreased compared with high expression level group (P<0.05), however, the expression level of miR-146a was not related to the overall survival rate. CONCLUSION Aberrant low expression levels of miR-21, miR-18a, and Let-7b derived from serum exosomes exist in patients with MM, which are associated with a worse overall survival rate.

BACKGROUND: Numerous studies have concentrated on high-dose radiation exposed accidentally or through therapy, and few involve low-dose occupational exposure, to investigate the correlation between low-dose ionizing radiation and changing hematological parameters among medical workers. METHODS: Using a prospective cohort study design, we collected health examination reports and personal dose monitoring data from medical workers and used Poisson regression and restricted cubic spline models to assess the correlation between changing hematological parameters and cumulative radiation dose and determine the dose-response relationship. RESULTS: We observed that changing platelet of 1265 medical workers followed up was statistically different among the cumulative dose groups (P = 0.010). Although the linear trend tested was not statistically significant (P CONCLUSION We concluded that although the exposure dose was below the limit, medical workers exposed to low-dose ionizing radiation for a short period of time might have increased first and then decreased platelets, and there was a dose-response relationship between the cumulative radiation dose and platelets changing.
