Bow hunter's syndrome,also referred to as rotational vertebral artery occlusion syndrome,is a rare etiological factor of posterior circulation infarction.This article reported a case of a young male patient who experienced recurrent posterior circulation infarctions caused by bilateral bow hunter's syndrome.Carotid ultrasonography confirmed a marked reduction in blood flow velocity in both vertebral arteries during neck rotation.High-resolution MR angiography and CT angiography of the head and neck revealed dissection involving the V3 segment of the left vertebral artery.The findings suggested that bow hunter's syndrome may be associated with thrombus formation secondary to repetitive mechanical compression of the vertebral artery intima,which could potentially lead to arterial embolism and subsequent cerebral infarction.This paper presents the patient's diagnostic and therapeutic course and includes a review of relevant literature aimed to enhance clinical awareness and understanding of this uncommon condition.

Objective To analyze the risk factors associated with intraoperative parathyroid injury during thyroid cancer surgery and develop a predictive model to evaluate its predictive efficacy.Methods A retrospective study was conducted involving 76 patients who experienced intraoperative parathyroid injury during thyroid cancer surgery between May 2021 and February 2024.These patients were included in the parathyroid injury group.For the control group,76 patients who underwent thyroid cancer surgery without intraoperative parathyroid injury during the same period were selected.Clinical data,complete blood count parameters,and other relevant variables were collected.Univariate analysis was performed to screen for potential risk factors,and Logistic regression analysis was used to identify independent risk factors.A regression predictive model was established,and the model's goodness-of-fit and predictive power were evaluated.Results Among the 76 patients,75 had temporary parathyroid function impairment and 1 had permanent parathyroid function impairment.Univariate and multivariate Logistic regression analyses showed that bilateral lymph node dissection,bilateral total lobectomy,capsule invasion,and combined hashimoto's thyroiditis were independent risk factors(P＜0.05).A predictive regression model was developed based on these factors.The Hosmer-Lemeshow test showed a x2=2.064,P=0.356,indicating good model fit.The receiver operating characteristic(ROC)curve revealed that the model had an area under the curve(AUC)of 0.713,with a 95％confidence interval(CI)of 0.639 to 0.787,suggesting good predictive efficacy.Conclusion Hashimoto's thyroiditis,capsular invasion,bilateral lymph node dissection,and bilateral total lobectomy are significant risk factors for intraoperative parathyroid injury during thyroid cancer surgery.The predictive model constructed based on these factors has good predictive efficacy.

Objective:To retrospectively analyze the clinical characteristics of 193 Chinese patients with McCune-Albright syndrome (MAS).Methods:By using keywords " McCune-Albright syndrome", " Albright syndrome", or " fibrous dysplasia " as the search terms, 193 cases of MAS reported in China from January 1990 to November 2022 from the Wanfang data, CNKI, VIP, PubMed, and Embase databases were obtained, and their clinical data was retrospectively analyzed. Intergroup comparisons were carried out by using t test, Mann-Whitney U test, and χ2 test. Results:The 193 MAS patients had included 42 males and 151 females, with the median first-visit age of females being younger than males. The typical triad group had accounted for 46.1% of patients, and the middle first-visit and diagnosis age was younger than the atypical group. The primary reason for first-visit in males of MAS was fibrous dysplasia (FD), whilst that in females of MAS was peripheral precocious puberty (PPP). FD has occurred in 84.5% of the patients, with an average age of onset age being 6.1 years old, and 90% was ≤ 16 years of age. Endocrine hyperfunction was found in 79.3% of the patients, with a higher proportion in females compared with males ( P<0.05). Pituitary involvement was seen in 21.8% of the patients, and the incidence of craniofacial FD and cranial nerve compression was significantly higher in those with elevated growth hormone (GH) than without ( P<0.05). Café-au-Lait Spots were noted in 86.5% of the patients, and 28.3% (28/99) had located on the different side of FD. Conclusion:Most MAS patients had atypical manifestations and multi-systemic involvement. It is more common and occurs earlier in females. The most common reasons for initial diagnosis in male and female patients were FD and PPP, respectively. Patients with elevated GH should be examined for cranial nerve compression.

The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Objective:To analyze the current status of anesthesiology research in the world and China in 2023 and to identify the anesthesiology research hotspots using bibliometrics.Methods:The literature related to anesthesiology published in PubMed in 2023 was searched, and the country and author of the literature, as well as the key words of the literature were visually analyzed by using the software CiteSpace6.2. R4.Results:A total of 22 473 articles were included, the country with the largest number of publications was the United States, and China ranked second. The author with the highest number of publications in the field of anesthesiology in the worldwide in 2023 was Kaye Alan D from the United States. Chronic pain, general anesthesia and pain management were the research hotspots in the field of anesthesiology worldwide in 2023. The research hotspots in the field of anesthesiology in China focused on general anesthesia, oxidative stress and neuropathic pain.Conclusions:The United States is the leader in the research in the field of anesthesiology, with China following behind. The keywords of the literature in the field of anesthesiology between China and the world are roughly the same, reflecting the convergence of Chinese scientific research with global scientific research. Domestic anaesthesia practitioners can refer to or learn from the research hotspots of related countries and strengthen communication and cooperation between teams while conducting academic research.

Objective:To establish the first Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale in China and evaluate its preliminary application value in the standardized training for radiation oncology resident physicians.Methods:Based on the educational curriculum and examination requirements for the standardized training for radiation oncology resident physicians, as well as the standardized Mini-Clinical Evaluation Exercise (Mini-CEX) scale commonly used in clinical practice, the Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale was developed to facilitate the standardized training for resident physicians in the field of radiation oncology. In this prospective study, a randomization method using a random number table was employed to select a cohort of 26 resident physicians who completed their rotations in Department of Radiation Oncology at the Cancer Hospital, Chinese Academy of Medical Sciences from March 1, 2021 to December 31, 2021. The Mini-FERO scale was administered in the initial, middle, and final stages during the rotation period. The differences in evaluation scores before and after the assessments were analyzed by paired t-test. Furthermore, participating resident physicians and supervising teachers provided satisfaction ratings, and a comprehensive evaluation of the Mini-FERO scale was conducted. Results:The average scores of the three examinations of 26 resident physicians demonstrated a successive improvement, with individual performance in each assessed category also showing progressive enhancement. The second evaluation exhibited a more pronounced score increase compared to the first evaluation, with a mean improvement of (1.43±1.02) points ( t=7.13, P<0.001); while the third evaluation had a mean improvement of (0.41±0.50) points ( t=4.07, P<0.001) compaired to the second evaluation, with a mean difference of (1.02±1.15) points between the two ( t=4.53, P<0.001). The average time required for the assessments was (34.31±24.46) min. Overall satisfaction ratings from the evaluated resident physicians for the Mini-FERO scale were (8.42±0.85) points, and supervising teachers reported an overall satisfaction rating of (8.45±0.85) points. The satisfaction rate was 96% (25/26). Conclusions:In this study, the Mini-FERO scale was successfully developed and validated in the context of clinical teaching practice for radiation oncology resident physicians. The Mini-FERO scale is proven to be a feasible tool for assessing the gradual improvement of resident physicians throughout their learning process in the field of radiation oncology. Importantly, it offers the advantages of short assessment time, thereby avoiding additional burden on supervising teachers. The adoption of the Mini-FERO scale addresses current limitations of lacking of formative evaluation in the standardized training for radiation oncology resident physicians.

Objective:To investigate the changes of inflammation and immune function in children with chronic tonsillitis after tonsillotomy. Methods:Prospectively collected 60 children with obstructive sleep apnea （OSA） diagnosed as chronic tonsillitis with adenoids and tonsillar hypertrophy from January to June 2021. Two groups were divided, the experimental group （n=30） underwent bilateral partial tonsillectomy + adenoidectomy by hypothermia plasma ablation, and the control group （n=30） underwent adenoidectomy by using the same hypothermia plasma ablation method. The number of tonsillitis attacks before surgery and within one year after surgery was recorded, and the serum immunoglobulin IgM, IgG, IgA, complement C3 and complement C4 levels before operation, one month and three months after operation were measured. Results:The number of tonsillitis attacks in the experimental group and the control group at one year after surgery was lower than that before surgery（P<0.05）; The number of inflammatory attacks in the experimental group was （0.50±0.63） times/year, which was lower than that of （1.33±0.80） times/year in the control group. There was no significant difference in the five immunization results of the two groups at one month and three months after operation compared with before operation, and there was also no significant difference between the experimental and the control groups. Conclusion:Partial tonsillectomy can be applied to children with chronic tonsillitis, which can effectively reduce the number of tonsillitis attacks and has no effect on the immune function of children.

Objective:To investigate the risk factors and clinical significance of lymph nodes metastasis between sternocleidomastoid and sternohyoid muscle lymph node (LNSS) metastasis in thyroid cancer patients, so as to guide the reasonable dissection of LNSS region and lateral cervical lymph node in patients with papillary thyroid carcinoma (PTC) .Methods:We selected 111 PTC patients with lateral cervical lymph node metastasis who underwent radical thyroidectomy and lateral cervical lymph node dissection from Nov. 2018 to Dec. 2021 in China-Japan Union Hospital of jilin university. All patients were treated with low collar arc incision. Radical thyroidectomy and lateral cervical lymph node dissection were performed according to the guidelines, and lymph nodes in each district were grouped for pathological examination. According to whether LNSS metastasis occurred, they were divided into two groups: LNSS positive group (LNSS metastasis occurred) and LNSS negative group (LNSS metastasis did not happen). We collected the basic information of all 111 PTC patients with lateral lymph node metastasis (LLNM), preoperative color Doppler ultrasound examination and paraffin-embedded pathology and other related clinical case data. Then we described the clinicopathological features of cervical lymph node metastasis. Independent sample t test and Mann-Whitney U test were used for continuous variables, and Fisher exact test was used for data analysis for classified variables. Correlation analysis adopted binary logistics regression model, and analyzed the regularity and risk factors of LNSS metastasis. Results:In this study, the detection rate of LNSS was 64.9% (72/111), the overall LNSS metastasis rate was 7.2% (8/111), and the number of lymph node metastasis was 0-5. Univariate analysis showed that the location of LNSS metastasis was related with the cancer focus ( P<0.001), the preoperative serum thyroglobulin (Tg) level ( P=0.002), the number of lymph node metastasis in lateral cervical level Ⅳ ( P=0.001), the longest diameter of the cancer focus ( P=0.003) and the longest diameter of metastatic lymph nodes ( P=0.001) However, age, sex, whether there is lymph node metastasis in the central region (central lymph node metastasis ,CLNM), and whether there is multifocal cancer were not related to LNSS metastasis ( P≥0.05). Further multivariate analysis and work curve analysis of subjects showed that the tumor located in the lower pole ( P=0.014) and the number of lymph node metastasis in level Ⅳ more than 3 ( P=0.027) were independent risk factors for LNSS metastasis. It was found that the risk of LNSS metastasis increased when the cancer focus was located at the lower pole relative to the upper pole or middle part of the cancer focus ( OR=74.508, 95% CI: 2.373-2339.544). The number of lymph node metastasis in level Ⅳ had a positive effect on LNSS metastasis. The more lymph node metastasis in level Ⅳ, the higher the risk of LNSS metastasis ( OR=1.556; 95% CI=1.051-2.303) . Conclusions:In PTC patients with LLNM, the LNSS metastasis rate was 7.2%, and the advantages of LNSS cleaning outweigh the disadvantages. When the cancer focus is located at the lower pole and the number of lymph node metastasis in region Ⅳ is more than 3, it is necessary to pay attention to the dissection of this group of lymph nodes.
