ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group， with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain， short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group， administered once every other day， with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity， measured using the numerical rating scale （NRS） before and after treatment， and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate， the Eastern Cooperative Oncology Group （ECOG） Performance Status （PS） score， the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire （EORTC QLQ-C30） score， and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests， including routine blood， urine， stool， liver function， and kidney function， were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial， and both groups showed a decrease in average NRS scores and PS scores after treatment， with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group （P＜0.05 or P＜0.01）. After treatment， the NRS change rate in the Qihuang acupuncture group was （0.42±0.17）， significantly higher than that in the control group （0.14±0.27， P＜0.01）. The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group （P＜0.01）. The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30， and a decrease in symptom scores for fatigue， nausea and vomiting， pain， dyspnea， insomnia， appetite loss， constipation， and financial difficulties. In contrast， overall health status and constipation scores in the control group increased， while scores of fatigue， nausea and vomiting， pain， and appetite loss decreased （P＜0.05 or P＜0.01）. After treatment， the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group （P＞0.05）， while the control group showed a significant increase in the 24-hour dose （P＜0.01）. No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study， the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% （1/33）， while the incidence in the control group was 27.27% （9/33） and 36.36% （12/33）， respectively， with the Qihuang acupuncture group showing significantly lower incidence （P＜0.01）. No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life， reduce the dose of opioid analgesics， and has good safety.

Objective To preliminarily investigate the association between changes in intestinal microbiota and oral microbiota of allogeneic hematopoietic stem cell transplantation(allo-HSCT)patients and early gastrointestinal acute graft versus host disease(aGVHD),and try to explore potentially effective biomarkers and provide theoretical basis for early prediction and intervention of gastrointestinal aGVHD.Methods Ten acute leukemia patients who developed gastrointestinal aGVHD within 1 month after receiving allo-HSCT in Department of Hematology of Sichuan Provincial People's Hospital from September 2021 to June 2023 were enrolled,and their fecal samples and saliva samples before and after the aGVHD were collected.16S rRNA sequencing analysis was applied for the differential changes in intestinal and oral microbiota before and after the development of early gastrointestinal aGVHD.Results ① A decrease in Bacteroides spp.and an increase in Enterococcus spp.and Enterobacteriaceae spp.in the intestinal microbiota were positively correlated with the occurrence of early upper gastrointestinal aGVHD(P＜0.05),whereas no significant difference was observed in the overall microbial diversity of the oral microbiota(P＞0.05).② LEfSe analysis of the intestinal microbiota before and after gastrointestinal aGVHD revealed an increase in Klebsiella spp.and Enterococcus spp.and a decrease in Escherichia coli;In the oral microbiota,LEfSe analysis revealed 10 microbial markers with significant difference,of which Gamma proteobacteria was the most significant.③ The difference in β-diversity of the intestinal microbiota was significant(P=0.03),whereas there was no significant difference in the α-and β-diversity of the oral microbiota.Conclusion Significant differences are found in intestinal microbiota before and after the occurrence of early gastrointestinal aGVHD in patients after Allo-HSCT,and the occurrence may have a correlation with the chang in oral microbiota.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Objective:To explore the efficacy and safety of cryopreservation-free integrated autologous hematopoietic stem cell transplantation (HSCT) model for patients with multiple myeloma.Methods:A total of 96 patients with newly diagnosed multiple myeloma (NDMM) between July 31, 2020, and December 31, 2022, were retrospectively analyzed, of which 41 patients in the observation group received integrated non-cryopreserved transplantation mode. After hematopoietic stem cells were mobilized and collected, melphalan was started immediately for pre-transplant conditioning, and non-cryopreserved grafts from the medical blood transfusion refrigerator were directly injected intravenously into the patient within 24-48 h after the melphalan conditioning. The control group consisted of 55 patients who received traditional transplantation mode. After hematopoietic stem cells were collected, stem cell cryopreservation was performed in liquid nitrogen, and then the transplant plans were started at the right time. All patients received mobilization of autologous hematopoietic stem cells using the G-CSF combined with the plerixafor.Results:① A total of 34 patients (82.9% ) with VGPR plus CR in the observation group were significantly higher than 33 patients (60.0% ) in the control group ( P=0.016). ②Compared with the control group, the incidence of grade 1 oral mucosal inflammation was higher in the observation group ( P<0.001) ; however, the incidence of grades 2 and 3 oral mucosal inflammation was lower ( P=0.004, P=0.048), and neither group experienced grade 4 or above oral mucosal inflammation. The incidence of grade 1 diarrhea was higher in the observation group ( P=0.002), whereas the incidence of grade 3 diarrhea was lower ( P=0.007). No statistically significant difference was observed in the incidence of grade 4 diarrhea ( P=0.506), and neither group experienced grade 5 diarrhea. ③ The incidence of bacterial infection in the observation group was lower than that in the control group (34.1% vs 65.5%, P=0.002), whereas no statistically significant difference was observed in the incidence of fungal infection (29.3% vs 31.4%, P=0.863) and viral infection (4.88% vs 3.64%, P=0.831). ④No statistically significant difference was observed in the implantation time of granulocytes and platelets between the observation and control groups [10 (8-20) days vs 11 (8-17) days, P=0.501; 13 (10-21) days vs 15 (10-20) days, P=0.245]. ⑤ All patients did not receive lenalidomide treatment 100 days post-transplantation. At 30 days post-transplantation, the CTL, NK, and Th cell counts in the observation group were lower than those in the control group ( P<0.001, P=0.002, P=0.049), and the NKT cell counts were higher than those in the control group ( P=0.024). At 100 days post-transplantation, the CTL, NKT, and Th cell counts in the observation group were higher than those in the control group ( P=0.025, P=0.011, P=0.007), and no statistically significant difference in NK cell counts was observed between the two groups ( P=0.396). ⑥ The median follow-up was 18 (4-33) months. The overall 2-year survival rates of the observation and control groups post-transplantation were 91.5% and 78.2%, respectively ( P=0.337). The recurrence-free survival rates were 85.3% and 77.6%, respectively ( P=0.386), and the cumulative recurrence rates were 9.8% and 16.9%, respectively ( P=0.373) . Conclusion:In NDMM, the cryopreservation-free integrated autologous HSCT model can achieve similar therapeutic effects as traditional transplantation models, with lower rates of severe mucosal inflammation and infection compared with traditional transplantation models.

Chest wall tumor(CWT) is a heterogeneous tumor involving multiple systems, including primary and secondary tumors. Chest wall tumors should first be classified according to their histological origin before distinguishing between benign and malignant. Except for a very few malignant tumors, surgical resection is the first choice for the treatment of chest wall tumors. However, chest wall tumors are different from other tumors in that resection of these tumors will compromise the integrity and stability of the chest wall, which makes it necessary before surgery to evaluate not only whether the tumor can be resected, but also the necessity and feasibility of postoperative chest wall reconstruction. With the progress of medical technology, the styles and methods of surgical treatment of chest wall tumors have also made marked advancements. This article aims to briefly review the changes and developments of surgical treatment of chest wall tumors in recent years, so as to provide a reference for clinical work.

Objective To explore the key active ingredients and action characteristics of Wenxing Jingjintong Gel Patch in the treatment of rheumatoid arthritis(RA)based on the systematic pharmacology and LC-MS/MS technology.Methods The information of active ingredient from Wenxing Jingjintong Gel Patch was established through LC-MS/MS analysis and literature retrieval.The targets of the active ingredients were predicted using Swiss Target Prediction platform and then mapped with the RA-related targets obtained from GeneCards,DrugBank,and OMIM databases to identify the intersecting targets.The"active ingredients-effective targets"network was constructed through the Cytoscape software.The shared targets were imported into STRING database to construct a protein-protein interaction network.GO function and KEGG pathway enrichment analysis were performed using the Metascape database.Molecular docking studies were conducted using AutoDock software to investigate the interactions between key ingredients and target proteins.Results A total of 142 active ingredients were identified in Wenxing Jingjintong Gel Patch by wsing LC-MS/MS,which were further supplemented to 174 through literature retrieval.There were 175 shared targets between the active ingredients and RA.It was anticipated that Wenxing Jingjintong Gel Patch exerted immune regulation and anti-inflammatory and analgesic effects through the interaction between key active ingredients such as berberine,neobavaisoflavone,and palmatine chloride with key targets,including TNF,IL6,and AKT1 to regulate PI3K/Akt1,JAK/STAT,and MAPK signaling pathways.In 1 152 molecular docking validation,94%of them had binding energies less than-5.0 kcal·mol-1,while 51%of them had binding energies less than-7.0 kcal·mol-1.It was indicated that there was a good binding affinity between the potential active ingredients and core targets.Conclusion This study predicted the active ingredients and action characteristics of Wenxing Jingjintong Gel Patch in the treatment of RA,which provided a theoretical basis for further clinical application and quality control.

Interleukin-17(IL-17)is an important pro-inflammatory cytokine that bridges innate and adaptive immunity,promoting protective immunity against pathogens,but also driving inflamma-tory pathology during infection and autoimmunity.IL-17 has important protective roles in a variety of bacterial zoonoses,but also promotes the development of inflammatory diseases in various organ tissues and is associated with autoimmune diseases induced by bacterial infections.Recent studies have shown that IL-17-secreting CD4+tissue-resident T memory cells play a key role in sustaining adaptive immunity to bacterial infections,and vaccine design strategies targeting IL-17 responses exhibit apparent advantages in improving vaccine efficacy.In this regard,this paper reviews the bio-logical functions of IL-17 and its roles in major bacterial zoonoses and related mechanisms,with the aim of providing a reference for the development of safe and effective IL-17-based immunother-apies.

Innate immunity is the front line of the antiviral immune response and the bridge to a-daptive immunity.Porcine reproductive and respiratory syndrome virus(PRRSV)has evolved mul-tiple strategies to evade the host's innate immunity and thus establish persistent infections,which is one of the biggest obstacles to control PRRSV infection.In antiviral innate immunity,type Ⅰ in-terferons,interferon-stimulated genes(ISGs),and other antiviral proteins are the main perform-ers,cellular autophagy and programmed cell death are important components,noncoding RNAs are key regulators.Studies on evasion mechanisms of innate immune by PRRSV have emerged in re-cent years,greatly expanding our understandings of the PRRSV-host interaction network.In this paper,we outline the latest researches on PRRSV inhibition of type Ⅰ interferon production and its signaling transduction as well as antagonism of ISGs and other antiviral proteins,and focus on summarizing the researches on PRRSV evade the innate immunity through the modulation of cel-lular autophagy,programmed cell death,and non-coding RNAs,with a view to providing ideas for subsequent research and anti-PRRSV vaccine and drug development.

Objective:To explore the incidence and risk factors of severe bleeding after percutaneous renal biopsy (PRB) in patients with advanced chronic kidney disease (CKD).Methods:The study was a retrospective cohort analysis. The data were collected from patients with advanced CKD who were hospitalized in the Department of Nephrology, Nanfang Hospital, Southern Medical University and underwent PRB between January 2010 and December 2020. Severe bleeding after PRB was defined by any of the following criteria: a postoperative hemoglobin decrease of ≥20 g/L within 48 hours, a maximum diameter of perirenal hematoma ≥5 cm postoperatively, or the need for posterior pituitary hormone, blood transfusion, or renal vascular intervention post-surgery. The occurrence of severe bleeding following PRB served as the primary endpoint for this study. Logistic regression model was used to analyze the risk factors associated with severe bleeding in patients with advanced CKD undergoing PRB.Results:A total of 895 patients aged (46.1±14.1) years were encompassed in the study. Among them, 60.1%(538/895) were male, 15.9%(142/895) were afflicted with diabetes, and 57.9%(518/895) suffered from hypertension. The estimated glomerular filtration rate (eGFR) was (40.1±13.2) ml?min -1?(1.73 m 2) -1, and the 24-hour urine protein excretion was 2.5(1.1, 4.9) g. After PRB, 22.9%(205/895) of the patients encountered severe bleeding, including 30 patients (14.6%) who received postoperative somatostatin, 10 patients (4.9%) who underwent postoperative blood transfusion, 1 patient (0.5%) who underwent postoperative renal vascular intervention for hemostasis, and no fatalities occurred. Compared to the non-severe bleeding group, patients in the severe bleeding group after PRB exhibited a higher proportion of hypertension [64.4%(132/205) vs. 55.9%(386/690), χ2=4.627, P=0.031]. Additionally, preoperative serum creatinine levels and mean arterial pressure were significantly elevated [(193.9±106.6) μmol/L vs. (180.8±102.6) μmol/L, t=-2.559, P=0.011; (95.8±10.9) mmHg vs. (93.9±11.0) mmHg, t=-2.134, P=0.033]. Furthermore, platelet counts were lower in the severe bleeding group [(227.5±70.3) ×10 9/L vs. (247.5±74.8) ×10 9/L, t=-3.788, P<0.001]. No statistically significant differences were observed between the two groups regarding age, gender distribution, prevalence of diabetes mellitus, as well as preoperative serum albumin level, hemoglobin concentration, other coagulation function indicators and pathological histological type (all P>0.05). Multivariate logistic regression analysis indicated that body mass index ( OR=0.936, 95% CI 0.891–0.984, P=0.010), eGFR ( OR=0.985, 95% CI 0.971–0.999, P=0.034), serum albumin level ( OR=1.041, 95% CI 1.011–1.072, P=0.007), 24 hours urinary protein excretion ( OR=1.092, 95% CI 1.030–1.158, P=0.003), and platelet count ( OR=0.996, 95% CI 0.994–0.999, P=0.002) were independently associated with the severe bleeding following PRB in patients with advanced CKD. In the PRB cohort analyzed, the six most prevalent renal histological types were as follows: IgA nephropathy (46.3%, 414/895), membranous nephropathy (11.1%, 99/895), focal segmental glomerulosclerosis (8.5%, 76/895), diabetic nephropathy (7.6%, 68/895), sclerotic kidney disease (6.9%, 62/895), and vascular sclerosis of the kidneys (4.9%, 44/895). Conclusions:Patients with advanced CKD exhibit a heightened risk of severe bleeding following PRB, estimated at approximately 22.9%. Independent risk factors for the occurrence of severe bleeding complications in these patients include low body mass index, reduced eGFR, decreased platelet count, elevated serum albumin, and increased urinary protein level.
