ObjectiveTo investigate the effect of video-based educational intervention combined with maternal presence on perioperative adverse outcomes in preschool children undergoing general anesthesia， including cooperation in anesthesia induction， perioperative anxiety， pain and agitation during recovery. MethodsA total of 300 preschool children scheduled for general anesthesia in our hospital from June to December 2023 were randomly assigned to control group （n=150） and intervention group （n=150）. The control group received routine recovery care. For the intervention group， in addition to routine recovery care， a preoperative visit was scheduled one day before surgery. During this visit， mothers were guided to watch anesthesia videos with their children. During the waiting period in the operating room and 30 minutes after awakening， the mothers were guided to accompany the children for more than 30 minutes. Recovery conditions were recorded using the surgical anesthesia information system， and the children’s anesthetic induction compliance， perioperative anxiety， pain， and agitation were evaluated and recorded using the modified Yale Preoperative Anxiety Scale （m-YPAS）， the Induction Compliance Scale （ICC）， the Children’s Pain Behavior Scale （FLACC）， and the Pediatric Agitation and Emergence Delirium Scale （PAED）. ResultsOn the preoperative visit day， there were no statistically significant differences in baseline data between the two groups （P > 0.05）. For perioperative anxiety， the m-YPAS scores of the intervention group were significantly lower than those of the control group， both when entering the operating room waiting area （35.27±6.48 vs. 41.79±6.68， P < 0.05） and 30 minutes after postoperative recovery （20.13±7.05 vs. 35.75±9.51， P < 0.05）. In terms of anesthesia induction cooperation， the ICC scores of the intervention group were significantly lower than those of the control group （1.84±0.95 vs. 3.17±0.62， P < 0.05）， and the proportion of good induction cooperation was significantly higher than that of the control group （24.00% vs. 12.67%， P < 0.05）. There was no significant difference in awakening duration between the two groups， but the intervention group had a significantly shorter length of stay in the post-anesthesia care unit than the control group （0.90±0.29 hours vs. 1.29±0.42 hours， P < 0.001）. For perioperative agitation， the PAED scores of the intervention group were significantly lower than those of the control group （entering in the operating room waiting area： 8.5 vs. 9.2， P < 0.05； 30 minutes after postoperative recovery： 4.2 vs. 7.8， P < 0.05）. In terms of pain scores， the FLACC scores of the intervention group were also significantly lower than those of the control group， both when entering the operating room waiting area （ 5.3 vs. 6.7， P < 0.05； 30 minutes after postoperative recovery： 2.1 vs. 4.9， P < 0.05）. ConclusionsVideo-based educational intervention combined with maternal presence reduces the perioperative anxiety， pain and agitation of preschool children undergoing general anesthesia， and improved the compliance of anesthesia induction. It is recommended to promote this intervention measure in clinical practice.

Objective:To explore the effect of comprehensive moxibustion with Huolong cupping in patients with lung-spleen qi deficiency type allergic rhinitis.Methods:This study was a randomized controlled trial. From October 2022 to April 2023, convenience sampling was used to select 66 patients with lung-spleen qi deficiency type allergic rhinitis who visited the Otolaryngology Head and Neck Clinic of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine as the research subject. The patients were randomly divided into an experimental group ( n=33) and a control group ( n=33). Both groups received routine oral Chinese medicine treatment. On the basis of routine treatment, the experimental group performed comprehensive moxibustion with Huolong cupping on the meridians of the Du meridian and bladder meridian. This study compared the scores of Nasal Airway Resistance (NAR), Total Nasal Symptom Score (TNSS), Visual Analogue Scale (VAS), and Chinese version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) between two groups of patients before and after intervention. Results:Eventually 30 patients in each of the experimental group and control group completed the study. After intervention, the NAR score of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05). Repeated measures analysis of variance showed that with the increase of treatment time, the TNSS, VAS, and RQLQ scores of the experimental group were lower than those of the control group with statistical differences ( P<0.05), and the time effect, inter group effect, and interaction effect were statistically significant ( P<0.05) . Conclusions:Huolong cupping comprehensive moxibustion can reduce nasal resistance, meliorate nasal symptoms and accompanying nasal symptoms, and improve the quality of life of patients.

Skeletal muscle dysfunction is a common extrapulmonary disease in patients with chronic obstructive pulmonary disease (COPD) , and about 92% of COPD patients have skeletal muscle dysfunction. In order to effectively deal with and control the skeletal muscle dysfunction in COPD patients, it is particularly important to choose a scientific and effective evaluation method to accurately and reliably assess the skeletal muscle function. This article reviews the common evaluation methods of skeletal muscle function in COPD patients from the aspects of muscle strength, muscle mass, muscle endurance, and exercise ability, and discusses the application status, advantages and disadvantages of different evaluation methods, so as to provide references for follow-up research and targeted intervention.

Objective:To explore the application of Bloom target teaching theory combined with PBL teaching mode in standardized residency training of respiratory.Methods:A total of 44 residents of Batch 2019 who had been in respiratory department of our hospital for 2 months on rotation were selected as the control group, and traditional teaching training was adopted in the group. In addition, 41 residents of Batch 2020 who were enrolled in the respiratory department of our hospital for a 2-month residency training rotation were selected as the research group, and Bloom target teaching theory combined with PBL teaching mode was applied in the group. After the residency training, the teaching effect of the two groups of training residents was evaluated by theoretical examination, practical skill operation examination and questionnaire survey. SPSS 22.0 was used to conduct t test. Results:The results of theoretical assessment and practical skills operation assessment of students in the study group were better than those in the control group, and the difference was statistically significant ( P<0.05). The subjective satisfaction of the training residents and the tutors were scored respectively. The results showed that the scores of residents in the study group were higher than those in the control group, the difference was statistically significant ( P<0.05). The subjective satisfaction score of residents on the assessment results of this stage showed that residents in the study group had higher scores than the control group, with statistical significance ( P<0.05). The tutor's subjective satisfaction score of the assessment results at this stage showed that the scores of the residents in the study group were higher than those in the control group, and the difference was statistically significant ( P<0.05). Conclusion:The combination of Bloom target teaching theory and PBL teaching mode can improve the theoretical and practical operation ability of students in respiratory department, improve their learning initiative, enthusiasm and teaching satisfaction, and then improve the teaching quality.

Objective: To evaluate the efficacies of lopinavir/ritonavir and abidol in the treatment of NCP. Methods: The clinical data of 134 patients with NCP receiving treatment at Shanghai Public Health Clinical Center during Jan 20 to Feb 6, 2020 were retrospectively collected. All the patients received interferon-α2b spray and symptomatic supportive treatment, and 52 cases received oral lopinavir/ritonavir treatment, 34 cases received oral abidol treatment, the remaining 48 cases did not take any antiviral drugs. The efficacies at median day 7 among the three groups were compared by using Kruskal-Wallis or chi-square tests. Results: The 134 patients included 69 males (51.5%) and 65 females, aged 35-62 years with the average of 48 years. The median time to temperature normalization in patients receiving abidol or lopinavir/ritonavir treatment was both 6 days after admission, and that was 4 days in the control group, with no significant difference (χ²=2.37, P=0.31). The median time to PCR negative in the respiratory specimens in the three groups was all 7 days after admission, and the PCR negative rates at day 7 after admission in lopinavir/ritonavir, abidol and control groups were 71.8% (28/39), 82.6% (19/23) and 77.1% (27/35), respectively, which were not significantly different (χ²=0.46, P=0.79). Radiological worsening at day 7 was observed in comparable proportions of patients in the three groups, which were 42.3% (n=22), 35.3% (n=12) and 52.1% (n=25), respectively (χ²=2.38, P=0.30) . Adverse reactions occurred in 17.3% (n=9), 8.8% (n=3) and 8.3% (n=4) patients, respectively in the three groups (χ²=2.33, P=0.33). Conclusions This study did not find any effects of lopinavir/ritonavir and abidol on relieving symptoms or accelerating virus clearance.

BACKGROUNDAdvances in transplantation immunology show that the balance between dendritic cells (DCs) and their subsets can maintain stable immune status in the induction of tolerance after transplantation. The aim of this study was to investigate if DCs and DC subpopulations in recipient peripheral blood are effective diagnostic indicators of acute rejection following kidney transplantation.

METHODSImmunofluorescent flow cytometry was used to classify white blood cells (WBCs), the levels of mononuclear cells and DCs (including the dominant subpopulations, plasmacytoid DC (pDC) and myeloid DC (mDC)) in peripheral blood at 0, 1, 7, and 28 days and 1 year after kidney transplantation in 33 patients. In addition, the blood levels of interleukin-10 (IL-10) and IL-12 were monitored before and after surgery. Fifteen healthy volunteers served as normal controls. Patients were undertaking hemodialysis owing to uremia before surgery.

RESULTSThe total number of DCs, pDC, and mDC in peripheral blood and the pDC/mDC ratio were significantly lower in patients than controls (P < 0.05). Peripheral DCs suddenly decreased at the end of day 1, then gradually increased through day 28 but remained below normal levels. After 1 year, levels were higher than before surgery but lower than normal. The mDC levels were higher in patients with acute rejection before and 1 day after surgery (P < 0.005). There was no significant difference in IL-10 and IL-12 levels between patients with and without acute rejection.

CONCLUSIONThe changes in DCs and DC subpopulations during the acute rejection period may serve as effective markers and referral indices for monitoring the immune state, and predicting rejection and reasonably adjusting immunosuppressants.
