Atrial fibrillation is the most common type of chronic cardiac arrhythmia. Catheter ablation and left atrial appendage occlusion are effective treatment methods for atrial fibrillation， but these procedures require anesthesia support. However， anesthetic drugs often cause side effects such as nausea， vomiting， involuntary movements， and respiratory depression. This paper presents a case of a successful one-stop procedure for cryoballoon ablation and left atrial appendage occlusion of atrial fibrillation performed entirely under acupuncture anesthesia. Thirty minutes before the procedure， acupuncture needles were inserted perpendicularly at bilateral Neiguan （PC 6）， Lieque （LU 7）， Ximen （PC 4） and （LU 6）. After obtaining the deqi （得气） sensation， an electroacupuncture device was connected， and electroacupuncture anesthesia was used for pain control throughout the procedure. The patient exhibited good tolerance and cooperation， with electroacupuncture anesthesia completely replacing intravenous anesthetics， ensuring the smooth completion of the surgery. Postoperative follow-up showed favorable outcomes.

Objective To analyze the clinical significance of subjective visual vertical (SVV) tests at different head deflection angles in assessing utricle function in patients with benign paroxysmal positional vertigo (BPPV). Methods A total of 61 BPPV patients who were treated at the Hearing Impairment and Vertigo Diagnosis and Treatment Center of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from August 2022 to May 2023 were retrospectively included, and 29 healthy adults were selected as controls. SVV tests were performed on all research subjects at different head deflection angles: upright head (0°), left head 45° (L45°), right head 45° (R45°). The test results between the two groups were compared. Results SVV absolute value at R45° in BPPV group was lower than that in the control group (P＝0.003); there was no significant difference in SVV values at 0° and L45° between the two groups. There was no statistical difference in SVV values at different head deflection angles between the control group and the left BPPV group. SVV absolute value at R45° in right BPPV group was lower than that in the control group (P＜0.001); there was no statistical difference in SVV values at 0° and L45° between the two groups. Conclusions SVV test can provide subjective information about the utricle, and SVV tests at different head deflection angles can fine-tune evaluate the function of the utricle in BPPV patients.

Objective:To understand the current status of the level of chronic disease prevention and treatment literacy and health anxiety among chronic disease residents, as well as the urban-rural differences, in order to provide a basis for improving the level of chronic disease prevention and treatment literacy among chronic disease residents.Methods:This was a cross-sectional study. From July to August 2022, a multi-stage random sampling method was adopted to select 201 rural residents with chronic diseases in one rural health center and 242 urban residents with chronic diseases in two community health service centers. General demographic characteristics questionnaire, Chronic Disease Prevention and Control Literacy Questionnaire and Short version of Health Anxiety Scale were used for questionnaire survey.Results:There were 93 males and 108 females with chronic diseases in 201 rural chronic disease residents, and the age range was 19-69 years. There were 116 males and 126 females with chronic diseases in 242 urban chronic disease residents, and the age range was 18-69 years old. The score of chronic disease prevention and control literacy of rural chronic disease residents (7.86 ± 2.25) was lower than that of urban chronic disease residents (8.55 ± 2.03). The score of health anxiety of rural chronic disease residents (13.69 ± 5.26) was higher than that of urban chronic disease residents (11.67 ± 5.95). Both differences were statistically significant ( t=-3.43, 3.79, both P<0.05). After controlling the general demographic data, the layered linear regression analysis of rural chronic disease residents and urban chronic disease residents showed that health anxiety can negatively affect rural chronic disease residents and urban chronic disease residents of chronic disease prevention and treatment literacy level ( β=-0.185, -0.129, both P<0.05). Conclusions:There are urban-rural differences in chronic disease prevention and treatment literacy and health anxiety of chronic disease residents in community. It is necessary to strengthen psychological construction among rural chronic disease residents in order to improve their chronic disease prevention and treatment literacy.

The comprehensive detection and identification of active ingredients in complex matrices is a crucial challenge.Liquid chromatography coupled with high-resolution mass spectrometry(LC-HRMS)is the most prominent analytical platform for the exploration of novel active compounds from complex matrices.However,the LC-HRMS-based analysis workflow suffers from several bottleneck issues,such as trace content of target compounds,limited acquisition for fragment information,and uncertainty in interpreting relevant MS2 spectra.Lycibarbarspermidines are vital antioxidant active ingredients in Lycii Fructus,while the reported structures are merely focused on dicaffeoylspermidines due to their low content.To comprehensively detect the new structures of lycibarbarspermidine derivatives,a"depict"strategy was developed in this study.First,potential new lycibarbarspermidine derivatives were designed according to the biosynthetic pathway,and a comprehensive database was established,which enlarged the coverage of lycibarbarspermidine derivatives.Second,the polarity-oriented sample prep-aration of potential new compounds increased the concentration of the target compounds.Third,the construction of the molecular network based on the fragmentation pathway of lycibarbarspermidine derivatives broadened the comprehensiveness of identification.Finally,the weak response signals were captured by data-dependent scanning(DDA)followed by parallel reaction monitoring(PRM),and the efficiency of acquiring MS2 fragment ions of target compounds was significantly improved.Based on the integrated strategy above,210 lycibarbarspermidine derivatives were detected and identified from Lycii Fructus,and in particular,170 potential new compounds were structurally characterized.The integrated strategy improved the sensitivity of detection and the coverage of low-response components,and it is expected to be a promising pipeline for discovering new compounds.

Objective:To investigate the expression of the novel immune checkpoint SIGLEC9 and SIGLEC9+T cells in cervical cancer and its clinical correlation.Methods:A total of 132 paraffin-embedded specimens of cervical tissue from patients with cervical cancer who under-went surgical treatment or pathological biopsy at The First Affiliated Hospital of Xinjiang Medical University from May 2022 to October 2023 were included for study.In addition,58 paraffin-embedded specimens of normal cervical tissue from patients with benign uterine leiomyomas who underwent total uterine excision during the same period were selected as normal controls.Furthermore,108 peripheral blood samples from patients with cervical cancer who underwent surgical treatment or pathological biopsy were collected for study,and 86 peripheral blood samples from healthy individuals during the same time period were selected as controls.Bioinformatics technology,im-munohistochemical(IHC)staining,flow cytometry,and double immunofluorescence(IF)staining were used to assess the expression of SIGLEC9 and SIGLEC9+T cells in cervical cancer,followed by correlation analysis with clinical indicators.Results:The bioinformatics,IHC,and double IF staining results showed that SIGLEC9 and SIGLEC9+T cells were highly expressed in cervical cancer tissues(P<0.05).The flow cyto-metry results showed that SIGLEC9+CD4+T and SIGLEC9+CD8+T cells were increased in the peripheral blood of patients with cervical cancer(P<0.05).SIGLEC9 expression correlated with tumor size,FIGO stage,lymph node metastasis,and human papillomavirus(HPV)infection(P<0.05).Conclusions:The novel immune checkpoint SIGLEC9 was highly expressed in cervical cancer tissues,and SIGLEC9+T cells infiltrated cervical cancer tissues.In vitro cell experiments showed that SIGLEC9 affects T cell function.In summary,SIGLEC9 provides a novel research direction for understanding the immune escape mechanism of cervical cancer and a novel therapeutic target for cervical cancer immuno-therapy.
