As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

Objective:To explore the impact of self-disclosure on demoralization syndrome in patients with permanent enterostomy for colorectal cancer, so as to provide reference for clinical nursing interventions for those patients.Methods:From January to May 2023, convenience sampling was used to select 207 patients with permanent enterostomy for colocrctal cancer of the Wound Ostomy Clinic of Laoshan Campus of the Affiliated Hospital of Qingdao University as the research subjects. A survey was conducted on patients using the General Information Questionnaire, Distress Disclosure Index, Social Support Rating Scale, and the Demoralization Scale Mandarin Version.Results:Among 207 patients with permanent enterostomy for colorectal cancer, the scores of self-disclosure, social support, and demoralization syndrome were 35.00 (26.00, 47.00) , 32.00 (26.00, 39.00) , and 35.00 (23.00, 47.00) , respectively. A total of 128 patients (61.8%) were in moderate demoralization, and 37 patients (17.9%) were in severe demoralization. Multiple linear regression analysis showed that place of residence, self-care of stoma, self-disclosure, and social support were the influencing factors for demoralization syndrome in patients with permanent enterostomy for colorectal cancer ( P<0.05) . Conclusions:Patients with permanent enterostomy for colorectal cancer have a high overall score of demoralization syndrome, and a high proportion of patients with moderate to severe demoralization. Medical and nursing staff should focus on patients in remote rural areas and those with poor self-care abilities to stomas, develop targeted intervention measures to improve patients' negative emotions, enhance their self-disclosure, and pay attention to strengthening social support to relieve their demoralization syndrome, thereby improving their quality of life.

Objective To create a mouse model of colorectal polyps with Apc-Kras-Cre gene mutations using the tamoxifen induction method.Methods Mice with Apc-Kras-Cre mutations were divided into four groups and injected intraperitoneally with different concentrations and dosages of tamoxifen for different durations,with group 1 injected with low dosage tamoxifen(5 mg/kg)for 1 day,group 2 injected with low dosage tamoxifen(5 mg/kg)for 3 days,group 3 injected with high dosage tamoxifen(50 mg/kg)for 1 day,group 4 injected with high dosage tamoxifen(50 mg/kg)for 3 days.C57BL/6J mice were used as a healthy control group and survival and changes in body weight were observed.All mice were euthanized 4 weeks post-tamoxifen induction and the colon length and number and size of intestinal polyps were observed.Histological changes in the intestinal tissue and polyps were detected by hematoxylin and eosin staining.Results The survival rate of male mice was higher(P＜0.001)and the morbidity rate of male mice was lower compared with female mice(P＜0.05).The survival rate differed significantly among the four groups(P＜0.01).All groups showed significant changes in body weight compared with the healthy control group(P＜0.001).There were also significant differences in weight changes between tamoxifen-induced groups 1 and 2,between groups 2 and 3,and between groups 1 and 4(P＜0.001,P＜0.01,P＜0.05,respectively).There were no significant differences in colon length between any treated group and the healthy control group(P＞0.05),but colon length did differ between tamoxifen-induced groups 1 and 3(P＜0.05).Polyp size varied in each group of tamoxifen-treated mice,with most polyps occuring at the distal end of the colon,while mice in groups 3 and 4 had more and larger polyps.Histopathological examination showed intestinal polyps with uneven and misaligned glandular and epithelial arrangements,a loosely-packed intestinal mucosal barrier,and irregularly-distributed crypts in tamoxifen-induced mice compared with the healthy control group,while mice in tamoxifen-induced groups 3 and 4 showed signs of inflammation and mice in group 4 showed necrosis of cells in some regions.Conclusions Tamoxifen-induced Apc-Kras-Cre model mice were successfully established,with the group 3 induction method being the most suitable.

Objective:To observe the effects of warming triple needling plus Chinese medication on inflammatory responses and daily functioning ability in patients with knee osteoarthritis(KOA)due to wind-cold-dampness Bi-impediment. Methods:A total of 101 patients with KOA due to wind-cold-dampness Bi-impediment were divided into an acupuncture-medication group and a Chinese medication group using the random number table method.Fifty cases in the Chinese medication group took oral Fang Feng Xi Bi Tang for treatment,and 51 cases in the acupuncture-medication group received additional warming triple needling therapy.The symptom score of traditional Chinese medicine(TCM),inflammatory factor levels,and motor function of the knee joint were compared before and after treatment.The clinical efficacy was also compared between the two groups after treatment. Results:Three cases in the acupuncture-medication group and 2 cases in the Chinese medication group dropped out during the study,and the two groups each had 48 cases being included in statistical analysis ultimately.The total effective rate was 95.8%in the acupuncture-medication group,higher than 79.2%in the Chinese medication group,and the between-group difference was statistically significant(P<0.05).After treatment,the TCM symptom score dropped in both groups(P<0.05)and was lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The levels of interleukin(IL)-6,tumor necrosis factor(TNF)-α,and IL-1β dropped after the intervention in both groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The scores of knee pain intensity,knee joint stiffness,and diurnal functioning decreased after treatment in the two groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05). Conclusion:Warming triple needling plus Fang Feng Xi Bi Tang can reduce inflammatory responses,improve daily functioning ability,and enhance the quality of life in patients with KOA due to wind-cold-dampness Bi-impediment.

"Tendency of disease" is an important concept in the theory of traditional Chinese medicine （TCM）. It was born out of and rooted in the thinking of "conducting by tendency" of ancient Chinese philosophy， meaning that the development and change of humans and nature have their own inevitable laws and dynamic tendencies. Based on the concept of holism and constant motion， the basic definition of "tendency"， the origin of the idea， the influence factors and related concepts were analysed， to grasp the overall connection in the dynamic changes in space and time， and to find a scientific and comprehensive objective law of development. The "tendency" was regarded as dynamic forces in the complex system， when yin and yang harmonized， called normal tendency； when fail to keep normal， called disease tendency； the season have sequential tendency， the earth has geographical tendency， people have body tendency， medications have medical tendency， and pulse has pulse tendency. Then the "eight methods of treating tendency" were summed up as observing tendency， evaluating tendency， waiting for tendency， accumulating tendency， favoring tendency， counteracting tendency， preventing tendency， and borrowing tendency， and condenses the methodo-logical thinking of "treatment according to disease tendency"， with a view to re-understanding the internal logic of TCM diagnosis and treatment， and providing metaphysical contemplation and exploration for the construction of a new paradigm of TCM syndrome differentiation and treatment.

OBJECTIVE: To investigate the correlation between postoperative driving pressure (DP) and the prognosis of lung transplantation, and to further evaluate the value of early DP monitoring in lung transplantation. METHODS: A observational study was conducted. The patients after lung transplantation who admitted to the intensive care unit (ICU) of Wuxi People's Hospital from February 1, 2022 to February 1, 2023 were collected. They were divided into low DP group (DP≤15 cmH₂O, 1 cmH₂O ≈ 0.098 kPa) and high DP group (DP > 15 cmH₂O) according to DP within 2 hours after operation. The clinical data including general information, primary disease, chronic diseases, cardiopulmonary function, laboratory indicators, intraoperative condition, postoperative lactic acid (Lac) and ventilator parameters were collected. Primary outcomes included 28-day and 90-day survival, and secondary outcomes included occurrence of primary graft dysfunction (PGD), duration of extracorporeal membrane oxygenation (ECMO), duration of mechanical ventilation, weaning of mechanical ventilation, and length of ICU stay. The general data and observations between the two groups were compared. Kaplan-Meier curve analysis was conducted to analyze the situation of mechanical ventilation and 90-day survival. Receiver operator characteristic curve (ROC curve) was used to evaluate the predictive ability of DP for failed weaning of mechanical ventilation and 90-day death. The dose-response relationship between DP and 90-day death risk was determined by restricted cubic spline model. Univariate analysis was performed using Cox proportional hazards model. RESULTS: A total of 101 patients were enrolled, with 68 patients (67.3%) in the low DP group and 33 patients (32.7%) in the high DP group. No statistically significant difference in general information, chronic diseases, primary diseases, cardiopulmonary function, laboratory indicators, intraoperative conditions, and postoperative Lac between the two groups was found. Compared with the low DP group, the patients in the high DP group had higher inspiratory pressure (Pinsp) and incidence of PGD with grade 3 at 24 hours after operation [Pinsp (cmH₂O): 21.0±0.6 vs. 20.0±0.7, PGD with grade 3 at 24 hours: 60.6% (20/33) vs. 39.7% (27/68), both P < 0.05], longer duration of ECMO, duration of mechanical ventilation, and the length of ICU stay [duration of ECMO (hours): 37 (21, 109) vs. 22 (14, 43), duration of mechanical ventilation (days): 3.1 (1.8, 10.7) vs. 1.9 (1.1, 3.2), length of ICU stay (days): 6 (3, 13) vs. 4 (3, 5), all P < 0.05], and lower successful weaning rate of mechanical ventilation [81.8% (27/33) vs. 95.6% (65/68), P < 0.05). The 28-day and 90-day survival rates in the high DP group were significantly higher than those in the low DP group [28-day: 69.7% (23/33) vs. 86.8% (59/68), 90-day: 63.6% (21/33) vs. 83.8% (57/68), both P < 0.05]. Kaplan-Meier curve showed that the patients in the low DP group were weaned and extubated earlier than high DP group, and the cumulative situation of weaning was better (Log-Rank test: χ ² = 14.054, P < 0.001), and the 90-day cumulative survival rate in the low DP group was significantly higher than that in the high DP group (Log-Rank test: χ ² = 4.791, P = 0.029). ROC curve analysis showed that the area under ROC curve (AUC) of DP for predicting 90-day death was 0.664 [95% confidence internal (95%CI) was 0.540-0.787, P = 0.017], and the AUC for predicting failed weaning of mechanical ventilation was 0.794 (95%CI was 0.667-0.921, P = 0.004). Results of restricted cubic spline model analysis showed that the 90-day death risk continued to increase with the DP < 18 cmH₂O; when DP≥18 cmH₂O, elevated DP did not continue to increase the 90-day death risk, showing a plateau effect. Univariate analysis showed that DP was independent risk factors of 90-day death, and the death risk increased by 9.3% for every 1 cmH₂O increase in DP [hazard ratio (HR) = 1.093, 95%CI was 1.007-1.186, P = 0.033]. CONCLUSIONS DP is an independent risk factor of death after lung transplantation, and early postoperative DP may be used as a predictor of failed weaning of mechanical ventilation and 90-day death after lung transplantation.

OBJECTIVE To mine the adverse drug reaction （ADR） signals of melphalan， so as to provide reference for clinically safe drug use. METHODS Using OpenVigil 2.1 data platform， relative ADR reports of melphalan from the first quarter of 2004 to the second quarter of 2022 in FAERS database were collected； data mining was conducted using the reported odds ratio （ROR） method and Medicines and Healthcare Products Regulatory Agency （MHRA） method of disproportional method. ADR reports were described and classified according to the system organ class （SOC） and preferred term （PT） in Medical Dictionary for Regulatory Activities （24.0 edition）. RESULTS A total of 17 046 ADR reports related to the target drug melphalan were retrieved， and the number of ADR reports showed a fluctuating upward trend； the majority of patients were male （43.28%）， and were concentrated between the ages of 50-＜75 （35.09%）， with the main reporting country being the United States （23.97%）； ADR report involved a total of 22 842 severe outcomes， mainly including hospitalization or extended hospitalization （24.45%）. Totally 403 ADR signals were detected， involving 23 SOC， mainly including blood and lymphatic system diseases （801 cases， 13.77%）， followed by eye organ diseases （755 cases， 12.97%） and infectious and invasive diseases （716 cases， 12.30%）. The ADR signals ranked high in the number of reported cases included febrile neutropenia， diarrhea， fever and mucositis and other PT； PT such as pneumonia， sepsis， vitreous hemorrhage， chorioretinal atrophy， myelodysplastic syndrome were not recorded in drug instructions. The ADR signals with high signal strength ranking included choroidal dystrophy， chorioretinal atrophy， eyeball atrophy and other PT， and above three types of PT were not included in the drug instructions. CONCLUSIONS ADRs caused by melphalan mainly include blood and lymphatic system diseases， eye organ diseases， and infectious and invasive diseases； before using melphalan， it is necessary to evaluate the drug use of patients， and pay close attention to the patient’s blood indicators and eye toxicity reaction， so as to guarantee the safety of treatment.
