Objective: To explore the network structure characteristics and core items of rural middle school students suffering from campus bullying and anxiety symptoms, so as to provide a reference basis for the precise prevention and intervention of the comorbidity of campus bullying and anxiety symptoms. Methods: From September 2021 to March 2022, a multi stage random cluster sampling method was used to select 1 920 rural middle school students from Xuzhou. The Chinese version of the Olweus Bully/Victim Questionnaire was used to investigate the situation of campus bullying, and the Chinese version of the Generalized Anxiety Disorder (GAD-7) was used to assess anxiety symptoms. The network analysis method was used to construct the network between suffering from campus bullying and anxiety symptoms of rural middle school students to evaluate the centrality, bridge strength, stability and accuracy of each item. Results: The total score of suffering from campus bullying symptoms of rural middle school students was (10.42±3.26) points, and the total score of anxiety symptoms was (11.47±4.93) points. The symptom with the highest strength and expected influence was "unable to stop or control one s worry emotions", and the node strength and expected influence value was 1.041 7. The nodes "feel nervous, anxious or irritable" and "unable to stop or control one s worry emotions" were most closely related. The symptoms with the highest bridge strength were "others give me ugly nicknames to scold me or make fun of and satirize me" and "unable to stop or control one s worry emotions". Conclusions Rural middle school students suffering from campus bullying is related to anxiety symptoms. Accurate intervention according to the intervention targets may minimize the negative impact of suffering from campus bullying and anxiety symptoms on rural middle school students.

Objective To compare the application effects of different anesthesia methods under preoper-ative optimization measures in elderly patients with hip fracture surgery.Methods A total of 120 elderly pa-tients (≥75 years old) with hip fracture surgery in this hospital from May 2022 to December 2023 were se-lected as the study subjects and divided into group A and group B,60 cases in each group.The two groups a-dopted the preoperative optimization measures.The group A performed "two single three low" (unilateral,once,low position,low concentration and low dose) lumbar anesthesia,while group B conducted the laryngeal mask artificial airway anesthesia.The hemodynamic changes at skin incision in operation beginning (T1),at 30 min after operation (T2),suture at operation end (T3),at the end of operation (T4) and at 30 min after opera-tion end (T5),postoperative recovery time and occurrence situation of complications such as nausea and vomi-ting,agitation,postoperative delirium (POD) were compared between the two groups.Results The systolic blood pressure and the heart rate at T1 in group B were lower than those in group A,and the differences were statistically significant (P<0.05).The systolic blood pressure and heart rate at T4 in group B were higher than those in group A,and the difference was statistically significant (P<0.05).The recovery time,agitation,nausea and vomiting and incidence rate of adverse reactions such as POD had no statistical difference between the two groups (P<0.05).Conclusion On the basis of preoperative optimization measures,selecting the "two single three low" lumbar anesthesia method in elderly patients with hip fracture surgery anesthesia has more stable hemodynamics,less complications and faster postoperative recovery.

Objective To investigate the effects of dexmedetomidine injection at the Neiguan acupoint before general anaesthesia on neurocognitive disorder and sleep quality after non-cardiac major surgery in eld-erly people.Methods Elderly patients undergoing elective thoracic and laparoscopic surgery in this hospital from February 2023 to March 2024 were selected and divided into the dexmedetomidine Neiguan acupoint in-jection group(A),saline Neiguan acupoint injection group(B)and dexmedetomidine intravenous injection group(C)by the randomised numerical table method,40 cases in each group.The postoperative neurocognitive function and sleep-related condition in the three groups were observed.Results The incidence rate of postop-erative delirium(POD)on postoperative 1 d in the group A and C was significantly decreased compared with the group B,and the difference was statistically significant(P＜0.05);the incidence rate of POD on postoper-ative 2 d in the group A was significantly decreased compared with the group B(P＜0.05);the incidence rate of postoperative cognitive dysfunction(POCD)on postoperative 1 d in the group A and C was significantly de-creased compared with the group B,moreover which in the group A was lower than that in the group C,and the differences were statistically significant(P＜0.05);the incidence rate of POCD on postoperative 3,5 d in the group A was lower than that in the group B(P＜0.05).The MMSE score on postoperative 1,3,5 d in the group B and C was significantly decreased compared with preoperative 1 d(P＜0.05).The MMSE score on postoperative 1,3,5 d in the group A and C was higher than that in the group B.and the difference was statis-tically significant(P＜0.05).The PSQI score on postoperative 1,3,5 d in the group A and C was increased compared with preoperative 1 d(P＜0.05);compared with the group B,the PSQI score on postoperative 1,3,5 d in the group A and C was decreased,moreover the group A was lower the group C,and the differences were statistically significant(P＜0.05).The incidence rate of bradycardia in the group A and C was signifi-cantly higher than that in the group B(P＜0.05).The incidence rate of postoperative nausea and vomiting(PONV)in the group A was significantly lower than that in the group B and C(P＜0.05),and the difference between the group B and C had no statistical significance(P＞0.05).Conclusion Dexmedetomidine injection at the Neiguan acupoint before anaesthesia for minimally invasive surgery can significantly reduce periopera-tive neurocognitive dysfunction(PND)and improve the quality of sleep in elderly patients,moreover simulta-neously has the effect for preventing PONV.

AIM: To investigate the mechanism of the involvement of SUMO-ylated Androgen receptor (AR) in tamoxifen resistance and the role of SUMO inhibitor ginkgolic acid in resistance. METHODS: Real-Time PCR was used to detect AR mRNA levels in parental cells MCF-7W and drug-resistant cells MCF-7R, AR protein levels and SUMO levels in MCF-7W and MCF-7R cells was performed by western blot, and CB/IP was applied to detect AR interacts with SUMOE3 ligase PIAS1 and HSP27 in MCF-7R cell chromatin, the transcriptional activity of SUMO AR was also evaluated by the fluorescent reporter gene experiment, the CCK-8 method and the trypan blue exclusion method were used to detect cell viability and cell viability respectively. RESULTS: The mRNA and protein expression levels of AR in MCF-7R cells were significantly higher than those in MCF-7W cells (P<0.05), and there was highly SUMOylated AR in MCF-7R cells. Further research found that there had an obvious interaction between AR and SUMO E3 ligase PIAS1 and HSP27, that was, the SUMOylated AR was modified by E3 ligase. Moreover, androgen R1881 could enhance the transcriptional activity of the SUMOylated AR in a concentration-dependent manner. Compared with ginkgo acid alone, 10 μmol/L of ginkgolic acid combined with 10 μmol/L of enzalutamide treated MCF-7R cells for 3 days, the cell number was significantly reduced, and the number of cell death increased significantly (P<0.05). CONCLUSION: The resistance mechanism of tamoxifen may be due to the enhanced AR transcription and activity increased by the hyperactive SUMOylated AR, SUMO inhibitor ginkgolic acid combined with AR antagonist enzalutamide can be a new strategy for the treatment of tamoxifen resistance.
