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.

To explore the correlation between the level of serum interleukin-6 (IL-6) and the severity of infection in patients with diabetic foot (DF) and the auxiliary value of IL-6 in DF diagnosis, and aim to provide reference for clinical treatment. Based on the hospital medical record system and the laboratory system, a retrospective analysis with case-control study was conducted on the data of patients in Liyuan Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 2020 to September 2024. A total of 377 patients′ information was collected, including 31 cases in control group with 17 males and 14 females from 31 to 91 years old and a median age of 71, 63 cases in NDF group with 43 males and 20 females from 37 to 96 years old, with a median age of 71, and 283 patients in DF group with 197 males and 86 females from 36 to 96 years, with a median age of 67. According to classification of infection severity, paints in the group of diabetes with DF were divided into mild infection subgroup (72 cases), moderate infection subgroup (143 cases) and severe infection subgroup (68 cases). The results showed that there were no statistically significant differences in age and gender among the three groups in the study ( F=1.795/ χ 2=2.81, P>0.05). The non parametric test results showed that there were statistically significant differences in IL-6, C-reactive protein (CRP), procalcitonin (PCT), white blood cell (WBC) and glucose (GLU) among the three groups of patients ( H=12.480, 36.277, 12.432, 12.838, 18.334, P<0.05). The pairwise comparison results showed that compared with the control group, the NDF group had higher levels of CRP, PCT and GLU ( H=20.259, 20.118, 20.056, P<0.05), and the levels of IL-6, CRP, PCT and WBC( H=14.934,14.933,14.829,14.934, P<0.05) were higher in the DF group. Both of the differences were statistically significant. But the difference of IL-6, CRP, PCT, WBC and GLU between the NDF and DF group was not statistically significant( H=1.202,0.622,0.737,1.036,1.899, P>0.05). In DF group, there were statistically significant differences in IL-6, CRP, PCT, WBC, and GLU levels among patients in the three infection subgroups ( H=11.174, 15.136, 8.657, 8.348, 3.698, P<0.05).Compared to the mild subgroup, the levels of IL-6, CRP, PCT, WBC and GLU were higher in the severe subgroup were higher( H=111.789,237.066,74.683,83.203,15.328, P<0.05) and the levels of IL-6, CRP, PCT in the moderate subgroup were higher ( H=6.877, 8.846, 5.183, P<0.05). And both of the differences were statistically significant. But there was no statistically significant difference in WBC and GLU level between the mild and the moderate subgroup( H=1.684, 1.039, P>0.05). The severity of infection in diabetic foot patients was positively correlated with the IL-6 level ( OR=1.033, 95% CI: 0.024-0.043, P<0.05). ROC curve showed that AUC of IL-6 for diagnosis in diabetic foots were 0.635. And joint testing showed that the AUC of IL-6+CRP, IL-6+PCT and IL-6+WBC were 0.718, 0.621, and 0.638 respectively. In conclusion,the level of serum IL-6 may be positively correlated with the severity of infection in diabetic foot patients, which may have auxiliary diagnostic value in predicting diabetic foot infection. And it may provide a reference for the grading of infection severity in diabetic foot patients to gauging serum IL-6 level.

BACKGROUND: Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths. METHODS: This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate. RESULTS: From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management. CONCLUSIONS The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

Objective To evaluate the clinical effects of the treatment of recurrent anterior dislocation of shoulder in soldiers with bipolar lesions by arthroscopic Bankart repair and Remplissage surgery.Methods From February 2019 to March 2022,15 patients with recurrent anterior dislocation of shoulder in our hospital were selected,all of whom were male;The age ranged from 18～33(23.07±4.39)years,Beighton score was(4.40±1.89).4 cases of left shoulder and 11 cases of right shoulder.Preoperative CT evaluation of Hill-Sachs injury was(16.93±2.17)%.The range of motion was recorded,and the function and stability of the shoulder was evaluated by the American Shoulder and Elbow Surgeons(ASES)score and Constant-Murley score.Results All patients were followed up for 10～28(18.47±6.46)months.No patient had clinical complications such as infections,neurovascular injuries and redislocation.Shoulder flexion and lifting increased from(152.41±14.28)° pre-operatively to(167.48±10.23)° at the latest follow-up,and internal rotation,preoperative spinous process levels were T5 1 cases,T6 2 cases,T7 6 cases,T8 3 cases,T9 2 cases,T10 1 cases,postoperative spinous process levels were T5 1 cases,T6 1 cases,T7 3 cases,T8 6 cases,T9 4 cases,the average lateral external rotation and abduction 90° external rotation decreased from(60.31±13.43)°and(97.41±13.17)° pre-operatively to(51.23±14.27)° and(89.47±14.15)° at the latest follow-up,respectively.The ASES score and Constant-Murley score were significantly improved.Conclusion The clinical effect of rehabilitation of Bankart repair combined with Remplissage under arthroscopy in the treatment of recurrent dislocation of shoulder in soldiers with Bipolar lesions is satisfactory.Although the external rotation angle of shoulder is slightly decreased after operation,it can significantly reduce the recurrence rate of shoulder dislocations and return to the training.

In the field of dental aesthetics,digital aesthetic design plays a crucial role in helping dentists to predict treatment outcomes vis-ually,as well as in enhancing the consistency of knowledge and understanding of aesthetic goals between dentists and patients.It serves as the foundation for achieving ideal aesthetic effects.However,there is no clear standard for this digital process currently in China and abroad.Many dentists lack of systematic understanding of how to carry out digital aesthetic design for treatment.To establish standardized processes for dental aesthetic design and to improve the homogeneity of treatment outcomes,Chinese Society of Digital Dental Industry(CSD-DI)convened domestic experts in related field to compile this consensus.This article elaborates on the key aspects of digital aesthetic data collection,integration steps,and the digital aesthetic design process.It also formulates a decision tree for dental aesthetics at macro level and outlines corresponding workflows for various clinical scenarios,serving as a reference for clinicians.

BACKGROUND:Atlantoaxial dislocation is often facilitated by interlaminar bone grafting.However,there are relatively few reports on the treatment of complex atlantoaxial dislocation with posterior atlantoaxial lateral mass interarticular release and fusion. OBJECTIVE:To explore the safety and effectiveness of atlantoaxial dislocation treated by simple posterior atlantoaxial lateral block interarticular release and fusion. METHODS:We retrospectively analyzed the clinical data of 30 patients with atlantoaxial dislocation who were treated from January 2017 to July 2021,all of whom suffered from reducible atlantoaxial dislocation.Posterior atlantoaxial lateral mass interarticular release and fusion were performed in all patients.During the surgery,patented instruments were used to release the atlantoaxial lateral mass joint,and posterior screw reduction and fixation were used with bone grafting in the lateral mass joint space.The postoperative follow-up period was 6 to 24 months,mean(13.0±5.4)months.During the follow-up period,cervical MRI was reviewed to observe the decompression of the upper cervical spine.X-ray films and CT scans were reviewed to observe the reduction of the upper cervical spine,as well as the internal fixation for looseness and breakage.CT scans were reviewed to assess interlateral block implant fusion.The Japanese Orthopaedic Association score was used to evaluate the improvement of spinal cord function.The neck disability index and the quality of life scale were used to assess the improvement of daily life function.The atlanto-anterior interspace and atlanto-planar spinal effective space were used to evaluate atlantoaxial repositioning and decompression. RESULTS AND CONCLUSION:(1)The surgery of 30 patients went smoothly,and no serious complications such as spinal nerve and vertebral artery injuries occurred during the operation.Postoperative review of cervical MRI showed that the spinal cord compression was lifted.X-ray film and CT showed that the atlanto-anterior gap was significantly reduced;the effective space of atlantoaxial spinal cord was significantly increased,and neurological dysfunctional symptoms were significantly reduced.(2)During the follow-up period,X-ray film and CT showed that the internal fixation was solid;no broken nails or rods occurred,and there was no recurrence of atlantoaxial dislocation.(3)The Japanese Orthopaedic Association scores,neck disability index,and quality of life scores were significantly improved at the last follow-up compared with the preoperative period(P<0.05).The average improvement rate of Japanese Orthopaedic Association scores at the last follow-up was 73.1%.The average neck disability index was 8.80%.All of the patients had a continuous bone-scalp connection between atlantoaxial lateral block joints to achieve osseous fusion.(4)These findings indicate that the use of simple posterior atlantoaxial lateral block interarticular release and fusion for the treatment of atlantoaxial dislocation can significantly increase the fusion rate and shorten the fusion time.

Objective:To explore the effect of transcutaneous electrical nerve stimulation (TENS) on interleukin-33 (IL-33)/growth stimulation expressed gene 2 (ST2) signaling pathway in the dorsal root ganglia (DRGs) of rats modeling hyperalgesia (HP).Methods:This study consisted of two experiments. In the first, 30 Sprague-Dawley (SD) rats were randomly divided into a blank group, a Sham-HP group, an HP group, an antibody group and an inhibitor group, each of 6. HP was induced in all except the rats of the blank and Sham-HP groups by injecting carrageenan (Car) and prostaglandin E2 subcutaneously at the bottom of the left hind feet. The antibody and inhibitor groups were then given intrathecal injections of anti-ST2 antibody and a tumor necrosis factor α (TNF-α)-specific inhibitor, respectively. In the second experiment, 42 SD rats were randomly divided into a Sham-HP group, an HP group, a TENSⅠgroup, a TENS II group, a TENS I inhibitor group, a TENS II inhibitor group, and a Sham-TENS group, each of 6. All of the groups had HP induced as in experiment one. All of the rats except those in the Sham-HP, HP and Sham-TENS groups were then given TENS, and the TENS I and II inhibitor groups were offered intrathecal injection of TNF-α-specific inhibitors. Mechanical pain thresholds (MPTs) were documented 4h, 24h, 48h, 72h, 6d, 7d 4h, 7d 1h, and 7d after the Car injections. Western blotting was used to measure the protein expressions of IL-33, ST2 and TNF-α 6d after the Car injection in both experiments.Results:In experiment one, the average MPTs of the HP, antibody and inhibitor groups had decreased significantly 4 hours after the Car injection compared with the blank and Sham-HP groups. However, 7d 1h after the Car injection the value had increased significantly in the Sham-HP, antibody and inhibitor groups compared with the HP group, while the expressions of IL-33, ST2 and TNF-α had decreased significantly. In experiment two, by 4 hours after the Car injection, the average MPT of all the other groups had decreased significantly compared with the Sham-HP group. Moreover, by 7d 1h after the Car injection, the average MPTs of the groups receiving TENS had increased significantly, with significantly lower MPT in the TENS Ⅱ group than in group Ⅰ, on average. There was also significantly higher expression of IL-33, ST2 and TNF-α in group II. Compared with the TENS Ⅰ and Ⅱ groups, the average MPT was significantly higher in the TENS I and Ⅱ inhibitor groups, but IL-33, ST2 and TNF-α expression was lower.Conclusions:TENS can inhibit TNF-α expression, which influences the signals of the DRG IL-33/ST2 signaling pathway to reverse hyperalgesia. TENS combined with anti-TNF-α treatment is superior to TENS alone in treating hyperalgesia.

Objective:To investigate the status of nursing practice and organizational management for reperfusion therapy in ischemic stroke across medical institutions in Beijing.Methods:In June 2023, a survey was conducted among nursing managers from 62 medical institutions under the jurisdiction of the Beijing Stroke Treatment Quality Control and Improvement Center. The survey aimed to assess the current nursing practices and organizational management for reperfusion therapy in ischemic stroke.Results:Among the 62 medical institutions, 16.13% (10/62) had dedicated reperfusion therapy nurses for stroke, and 87.10% (54/62) had established specific nursing protocols and procedures for stroke reperfusion therapy within their departments. However, 27.42% (17/62) of these institutions based the development and updates of their protocols on experiential summaries rather than standardized guidelines. In terms of nursing practice, there was room for improvement in emergency identification and triage of suspected stroke patients, assistance with intravenous thrombolysis, patient condition monitoring, early rehabilitation, and related health education. Regarding nursing quality control, significant differences were observed between institutions that regularly conducted quality control of stroke reperfusion therapy nursing and those that organized regular training sessions for nurses in this area ( P<0.05) . Conclusions:While nursing practices and quality for stroke reperfusion therapy in Beijing are progressing, there are disparities in regional development. There is a high demand for specialized stroke nursing and targeted technical training.
