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.

Diannan Su's bone-setting school is one of the orthopedic schools of traditional Chinese medicine(TCM),and Su Caichen,a famous bone-setting physician in Diannan,is the key figure of Diannan Su's bone-setting school.This paper systematically summarized Su Caichen's bone-setting academic thoughts of"adaptation","harmonization"and"recovery",presented his core bone-setting concepts of"original traumatic chamber","bone-setting prior to activating blood and vessles,bone-setting together with soothing tendons and then fracture healing naturally after the removal of stasis",and introduced his five kinds of bone-setting manipulations for treating the common upper limb fractures in detail,namely shaking and pushing manipulations for distal radius fracture,floating manipulations for fracture of both ulna and radius,five-step manipulations for supracondylar fractures of humerus,staging manipulations for humeral shaft fracture,and degloving manipulations for proximal humeral fractures complicated with shoulder dislocation.Su Caichen's bone-setting academic thoughts,bone-setting concepts and his specific TCM bone-setting manipulations have constructed the academic and theoretical system of Diannan Su's bone-setting school,which will provide an approach for TCM treatment of orthopedic diseases,and will promote the inheritance and development of the specific TCM orthopedic schools.

BACKGROUND:With the increase of the incidence of cervical spondylosis,it is particularly important to control the postoperative bleeding and related inflammatory reaction of cervical vertebra. OBJECTIVE:A prospective study was conducted to investigate the combined effect of intravenous and topical tranexamic acid of different concentrations on postoperative blood loss and inflammatory response during posterior cervical decompressive laminectomy combined with lateral mass screw internal fixation and bone graft fusion. METHODS:From January 2020 to December 2022,150 patients who were scheduled to undergo posterior cervical decompressive laminectomy combined with lateral mass screw internal fixation and bone graft fusion for cervical spondylotic myelopathy in Tianjin People's Hospital were enrolled in the study.Patients were divided into A,B,and C groups(n=50)by randomized double-blind lottery.The patients in the A,B,and C groups were treated with 1%,3%,and 5%intravenous and topical tranexamic acid solution,respectively.Postoperative blood loss and inflammation-related indicators were compared among three groups.The occurrence of venous thromboembolism and hematoma was observed after operation. RESULTS AND CONCLUSION:(1)There were significant differences in blood loss-related indexes,such as intraoperative blood loss,overall blood loss,and occult blood loss among the three groups(P<0.01).The above indexes were significantly lower in groups B and C than that in group A.There was no significant difference between groups B and C(P>0.05).(2)On days 1 and 3 after surgery,the levels of inflammatory indicators including serum C-reactive protein and interleukin-6 were increased to varying degrees in the three groups compared to before surgery(P<0.05).As the drug concentration increased,its expression decreased,and there was a significant difference among the three groups(P<0.001).(3)Two cases of intramuscular venous thrombosis appeared in each of the three groups after surgery.No hematoma or pulmonary embolism occurred in all three groups.(4)It is concluded that in posterior cervical decompressive laminectomy combined with lateral mass screw internal fixation and bone graft fusion,intravenous combined with topical application of different concentrations of tranexamic acid is effective in reducing perioperative blood loss and inflammatory response.3%tranexamic acid achieves the same effect without significantly increasing the risk of postoperative venous thromboembolism.

Objective The objective of this study was to establish a mouse model of allergic rhinoconjunctivitis and investigate the role of the NLRP3 signaling pathway in allergic rhinoconjunctivitis.Methods Thirty-three female C57 mice(SPF)were randomLy divided into 3 groups:the control group,the experimental group,and the NLRP3-/-group.On days 0,4,7,14,and 21,the experimental group and NLRP3-/-group received a 0.2 mL intraperitoneal injection of medicine containing OVA(100 μg)and adjuvant Al(OH)3(4 mg),respectively.After an interval of 3 days,each eye and nose were dosed with 10 μL of 5%OVA for five consecutive days a week to induce allergic symptoms.During sensitization and excitation stages,the control group was replaced with an equiva-lent amount of PBS.Ocular and nasal symptoms were observed and scored.The levels of OVA-specific IgE,IL-4,IL-17,and IL-18 in serum were measured using ELISA,while changes in palpebral conjunctiva and nasal mucosa were assessed by hematoxylin-eosin staining.The expression of NLRP3 mRNA in conjunctival tissue and nasal mucosa was determined using real-time PCR analysis.Statistical analysis was performed using SPSS17.0 software with P<0.05 considered as statistically significant difference.Results The experimental group and NLRP3-/-group exhibited induced nasal and ocular allergic symptoms.In the experimental group,the duration of nasal allergy symptoms was(10.500±1.080)days,while the duration of eye allergy symptoms was(20.300±2.058)days.In the NLRP3-/-group,the duration of nasal allergy symptoms was(13.400±1.955)days,and for eye allergy symp-toms it was(20.900±2.132)days.The duration of nasal allergies in the NLRP3-/-group significantly exceeded that in the experimental group(P<0.05),whereas there were no significant differences observed in eye allergy durations between these two groups(P>0.05).Levels of OVA-specific IgE,IL-4,and IL-17 were significantly higher in both the experimental and NLRP3-/-groups compared to those in the control group(P<0.05).Additionally,serum IL-18 content increased significantly in the experimental group when compared with both control and NLRP3-/-groups(P<0.05).Conjunctival tissue lesions as well as nasal mucosa damage were evident in both experimental and NLRP3-/-groups.mRNA expression levels of NLRP3 within conjunctival tissue and nasal mucosa from the experimental group showed a significant increase when compared to those from both control and NLRP3-/-groups(P<0.05).Conclusion Allergic rhinoconjunctivitis pathogenesis is influenced by various factors;however,the involvement of NLPR3 signaling pathway promotes its development.

The stem and branch extract of Tripterygium wilfordii (Celastraceae) afforded seven new dihydroagarofuran sesquiterpene polyesters [tripterysines A-G (1-7)] and eight known ones (8-15). The chemical structures of these new compounds were established based on combinational analysis of HR-ESI-MS and NMR techniques. The absolute configurations of tripterysines A-C (1-3) and E-G (5-7) were determined by X-ray crystallographic analysis and circular dichroism spectra. All the compounds were screened for their inhibitory effect on inflammation through determining their inhibitory effect on nitric oxide production in LPS-induced RAW 264.7 cells and the secretion of inflammatory cytokines TNF-α and IL-6 in LPS-induced BV2 macrophages. Compound 9 exhibited significant inhibitory activity on NO production with an IC₅₀ value of 8.77 μmol·L^-1. Moreover, compound 7 showed the strongest inhibitory effect with the secretion of IL-6 at 27.36%.

OBJECTIVEThe aim of this study was to analyze the initial displacement of the maxillary first molar by tip back bend in Tip-Edge force system and to explore the relationships between the displacement and the degree or position of tip back bend.

METHODSThe Tip-Edge three-dimensional finite element model was constructed by CT scan of a dry skull with all teeth. The conditions of five types of degree (20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees) and four types of position (2, 4, 6, 8 mm) of tip back bend were added to the three-dimensional finite element model and the initial displacements of the maxillary first molar were calculated.

RESULTSUnder the effect of tip back bend, distal and extrusive displacement of the maxillary first molar occurred. The distal and extrusive movement increased as the degree of tip back bend increased or the position of tip back bend moved distally.

CONCLUSIONThe initial displacement of the maxillary first molar could be controlled by the precise control of the degree and position of tip back bend.
