Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective: To analyze the trends in disease burden of tuberculosis among children under 5 years of age in China from 1990 to 2021, so as to provide insights for future tuberculosis control measures among children in China. Methods: Based on the Global Burden of Disease (GBD) 2021 datasets, the incidence, prevalence, mortality and disability adjusted life year(DALY) of tuberculosis of children under 5 years of age in China and globally were collected from 1990 to 2021. The incidence, prevalence, mortality and DALY rate of tuberculosis were compared by genders and types. In addition,the annual percent change(APC) and the average annual percent change(AAPC) of children s tuberculosis burden in China and globally from 1990 to 2021 were calculated by using the Joinpoint regression model, and the changing trends were analyzed. Results: The numbers of incident, prevalent and dead tuberculosis cases were 9 700, 8 477 800 and 200 among children under 5 years of age in China in 2021, and the DALY due to tuberculosis were 27 100 person years. There were significant reductions in incidence, prevalence, mortality and DALY rate of tuberculosis among children under 5 years of age in China ( AAPC =-5.45%, -1.14%, -12.37%, -11.34 %) and globally( AAPC =-2.38%, -1.41%, -4.66%, -4.56%), and the reductions in the incidence, mortality and DALY rate were more significant in China than globally ( P <0.05).In 1992 and later, the numbers of incident, prevalent and dead tuberculosis cases and the DALY of tuberculosis were higher among male than among female. In addition, the disease burden of drug susceptible tuberculosis appeared a tendency of downward in China from 1990 to 2021, while the incidence and prevalence of extensively drug resistant tuberculosis rose since 2015. Conclusions The disease burden of tuberculosis remarkably reduced among children under 5 years of age in China from 1990 to 2021. However, the burden of disease due to multidrug resistant tuberculosis appeared an upward trend recently. Increased attention is required to be paid to the prevention and control of tuberculosis among children and improved diagnosis and treatment of drug resistant tuberculosis are recommended.

Objective:To build a systematic and standardized nutrition management plan for patients with chronic kidney disease.Methods:Based on the nutrition care procedure and model, a preliminary draft of a nutrition management plan for chronic kidney disease patients was developed through a literature search, quality evaluation, and group discussions. After two rounds of expert consultation and revision of the preliminary draft of the nutrition management plan, the final plan was formed.Results:A total of 32 experts were invited to complete two rounds of consultation. In two rounds of expert consultation, 32 questionnaires were distributed, and 32 and 31 valid questionnaires were collected, with valid response rates of 100.0% and 96.9%, respectively. The expert authority coefficients were 0.853 and 0.871, respectively. The final nutrition management plan for chronic kidney disease patients included six first-level items of nutrition management personnel: nutrition risk screening, nutrition assessment, nutrition treatment, nutrition monitoring, and nutrition health education, with 23 second-level and 52 third-level items.Conclusions:The constructed nutrition management plan for chronic kidney disease patients is scientific and can provide a reference for nutrition guidance.

Objective:To test and evaluate the reliability and clinical effectiveness of osteoporotic thoracolumbar fracture (OTLF) scoring and classification system.Methods:A multicenter retrospective case series study was conducted to analyze the clinical data of 530 OTLF patients admitted to 8 hospitals including Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to June 2022. There were 212 males and 318 females, aged 55-90 years [(72.6±10.8)years]. There were 4 patients with grade C and 18 with grade D according to American Spinal Injury Association (ASIA) classification. According to the osteoporotic thoracolumbar injury classification and severity (OTLICS) score, all patients had an OTLICS score over 4 points and required surgical treatment. Among them, 410 patients had acute symptomatic OTLF (ASOTLF), including 24 patients with type I, 159 type IIA, 47 type IIB, 31 type IIC, 136 type IIIA, 8 type IIIB, 2 type IV (absence of neurological symptoms) and 3 type IV (presence of neurological symptoms), and 120 patients had chronic symptomatic OTLF (CSOTLF), including 62 patients with type I, 21 type II, 17 type III, 3 type IV (reducible under general anesthesia), 9 type IV (not reducible under general anesthesia), 1 type V (reducible under general anesthesia), 5 type V (presence of neurological symptoms), and 2 type V (not reducible under general anesthesia). Surgical procedures included percutaneous vertebroplasty (PVP), positional repositioning plus PVP, percutaneous kyphoplasty (PKP), posterior open reduction combined with bone graft fusion and bone cement augmented screw internal fixation, posterior open reduction combined with decompression, bone graft fusion and bone cement augmented screw internal fixation, and posterior open reduction combined with osteotomy and orthopedics, bone graft fusion and bone cement augmented screw internal fixation. A weighted Kappa was used to test the interobserver and intraobserver reliability of the OTLICS score, the ASOTLF classification, and the CSOTLF classification. The visual analog scale (VAS), Oswestry disability index (ODI), ASIA classification were compared before, at 1 month after surgery and at the last follow-up. Incidence of postoperative complications was observed.Results:The percentage of mean interobserver agreement for OTLICS staging was 93.4%, with a mean confidence Kappa value of 0.86, and the percentage of mean intraobserver agreement was 93.0%, with a mean confidence kappa value of 0.86. The percentage of mean interobserver agreement for ASOTLF staging was 94.2%, with a mean confidence Kappa value of 0.84, and the percentage of mean intraobserver agreement was 92.5%, with a mean confidence Kappa value of 0.83. The percentage of mean interobserver agreement for CSOTLF subtyping was 91.9%, with a mean confidence Kappa value of 0.80, and the percentage of mean intraobserver agreement was 91.3%, with a mean confidence Kappa value of 0.81. All the patients were followed up for 6-12 months [(9.0±2.1)months]. The VAS and ODI scores were significantly lower in patients with ASOTLF and CSOTLF classifications at 1 month after surgery and at the last follow-up than those before surgery (all P<0.05). The VAS scores in patients with ASOTLF types IIA, IIB, IIC, IIIA, and IV were significantly lower at the last follow-up than that at 1 month after surgery; the ODI scores in patients with ASOTLF types I, IIA, IIB, IIIA, IIIB and IV were significantly lower at the last follow-up than those at 1 month after surgery. The VAS scores in patients with CSOTLF types II, III, IV, and V were significantly lower at the last follow-up than those at 1 month after surgery, and the ODI scores in patients with all CSOTLF types were significantly lower at the last follow-up than those at 1 month after surgery (all P<0.05). Two patients with ASIA grade C recovered to grade D, and the rest recovered to grade E at the last follow-up ( P<0.01). No major vessel or nerve injury or internal fixation failure was found during follow-up. There were 18 patients with cement leakage, none of whom showed relevant clinical symptoms. There were 35 patients with new vertebral fractures, all of whom recovered well after symptomatic treatment. Conclusions:The OTLICS score, ASOTLF classification and CSOTLF classification have a high degree of reliability. Application of stepwise treatment for patients with different levels of injury according to the scoring and classification system can reduce pain, promote recovery of the spinal function, and reduce complications, which is of some significance in guiding the selection of clinical treatment.

Objective:To compare the efficacy of cervical decompression performed at different times in the treatment of incomplete cervical spinal cord injury.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 96 patients with incomplete cervical spinal cord injury admitted to six hospitals including Honghui Hospital affiliated to Xi'an Jiaotong University, etc, from May 2018 to May 2021. There were 36 females and 60 males, aged 28-42 years [(35.2±6.7)years]. The injured segments were at C 3 in 7 patients, C 4 in 15, C 5 in 20, C 6 in 23 and C 7 in 31. According to the American Spinal Injury Association (ASIA) scale, there were 59 patients with grade B, 27 grade C, and 10 grade D. A total of 36 patients underwent cervical decompression within 24 hours after injury (early group), 33 patients within 24-72 hours after injury (late group), and 27 patients within 4-14 days after injury (delayed group). The operation time, intraoperative blood loss, postoperative drainage, length of hospital stay, Cobb angle, height of intervertebral space and space occupation of the spinal canal before surgery and at postoperative 3 days, and ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, visual analog scale (VAS) score, Japanese Orthopedic Association (JOA) score, neck dysfunction index (NDI) before surgery and at postoperative 3 months, 1 year and at the last follow-up and incidence of complications were compared among the three groups. Results:All the patients were followed up for 12-21 months [(16.4±4.2)months]. There was no significant difference in the operation time among the three groups (all P>0.05). The intraoperative blood loss and postoperative drainage volume in the early group were (312.5±5.2)ml and (165.3±45.8)ml, which were higher than those in the late group [(253.5±40.0)ml, (120.4±60.6)ml] and the delayed group [(267.3±36.8)ml and (130.4±38.6)ml] (all P<0.01). There was no significant difference between the late group and the delayed group (all P>0.05). The length of hospital stay in the early group was (5.2±1.6)days, which was shorter than that in the late group [(7.6±2.3)days] and the delayed group [(8.0±1.3)days] (all P<0.05), but there was no significant difference between the late group and the delayed group ( P>0.05). There was no significant difference in the Cobb angle, height of intervertebral space and space occupation of the spinal canal among the three groups before and at postoperative 3 days (all P>0.05). There was no significant difference in the ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, VAS score, JOA score and NDI among the three groups before surgery (all P>0.05). At postoperative 3 months, 1 year and at the last follow-up, the ASIA grading of the early group was better than that of the late group and the delayed group ( P<0.05 or 0.01), but there was no statistically significant difference between the late group and the delayed group (all P>0.05). The ASIA motor scores of the early group were (56.4±4.5)points, (76.3±3.6)points and (85.4±6.5)points at postoperative 3 months, postoperative 1 year and the last follow-up, respectively, which were higher than those in the late group [(52.3±2.4)points, (60.3±8.6)points and (72.3±2.4)points] and the delayed group [(51.9±2.3)points, (62.8±4.6)points and (71.9±1.3)points]; the ASIA light tactile scores of the early group were (70.2±2.9)points, (72.6±4.3)points and (78.3±2.3)points, which were higher than those in the late group [(66.2±3.7)points, (68.3±1.6)points and (73.3±1.6)points] and the delayed group [(65.2±2.1)points, (67.8±1.9)points and (72.3±2.5)points]; acupuncture sensation scores of the early group were (71.9±3.1)points, (80.1±3.8)points and (89.1±7.6)points, which were higher than those in the late group [(67.4±2.7)points, (72.6±3.7)points and (77.9±1.8)points] and the delayed group [(68.3±2.2)points, (72.6±3.1)points and (77.2±1.9)points] (all P<0.05). VAS scores of the early group at postoperative 3 months, 1 year and at the last follow-up were (4.3±0.6)points, (2.4±0.3)points and (1.6±0.2)points, which were lower than those in the late group [(5.1±1.3)points, (4.1±0.6)points and (3.0±0.6)points] and the delayed group [(5.0±1.7)points, (4.0±0.8)points and (3.1±0.2)points]; JOA scores of the early group were (12.8±1.6)points, (14.4±2.6)points and (17.9±3.3)points, which were higher than those in the late group [(11.9±1.9)points, (13.3±1.6)points and (8.9±1.3)points] and the delayed group [(11.6±1.8)points, (13.2±1.4)points and (9.3±2.1)points]; NDI scores of the early group were 12.1±3.3, 10.1±2.1 and 7.3±1.4, which were lower than those in the late group (14.4±3.1, 12.3±1.6 and 8.9±1.3) and the delayed group (14.1±2.3, 12.9±1.9 and 9.5±2.1) (all P<0.05). There was no significant difference in all the above-mentioned scores at postoperative 3 months, 1 year and at the last follow-up between the late group and the delayed group (all P>0.05). The incidence of complications was 25.0% (9/36) in the early group, 27.3% (9/33) in the late group and 37.0% (10/27) in the delayed group (all P>0.05). Conclusion:Compared with within 24-72 hours and 4-14 days after injury, cervical decompression performed within 24 hours after injury for patients with incomplete cervical spinal cord injury can shorten the length of hospital stay, improve the function of the spinal cord nerves and relieve pain, with no increase of the incidence of complications.

Objective:To compare the application effect of whole-process seamless nursing and conventional nursing in the perioperative period of ankylosing spondylitis (AS) with kyphosis complicated by cervical spine fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 64 patients with AS with kyphosis complicated by cervical spine fracture admitted to Henan Provincial People′s Hospital from April 2017 to December 2022, including 37 males and 27 females, aged 27-73 years [(49.8±14.6)years]. There were 43 patients with vertebral fractures and 21 with intervertebral space fractures. All patients underwent reduction and fixation or correction and fixation. Thirty-two patients admitted from April 2017 to August 2019 received conventional care (conventional nursing group), and 32 patients admitted from September 2019 to December 2022 received whole-process seamless care (seamless nursing group). The two groups were compared concerning the visual analog scale (VAS) before, at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, the American Spinal Injury Association (ASIA) score before surgery, at 1 and 3 months after surgery and at the last follow-up, the health survey questionnaire (SF-36) score and patient satisfaction score before surgery and at the last follow-up, as well as the incidence of postoperative complications.Results:All patients were followed up for 6-12 months [(9.8±3.2)months]. There was no statistical difference in preoperative VAS between the two groups ( P>0.05). The values of VAS in the seamless nursing group were (3.9±1.9)points, (4.2±0.7)points, (2.7±0.9)points, (2.6±0.6)points, and (1.7±0.8)points at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, respectively, lower than those of the conventional nursing group [(5.7±1.2)points, (5.8±1.1)points, (3.6±1.2)points, (3.2±1.1)points, and (2.4±1.0)points] ( P<0.05 or 0.01). The VAS of the seamless nursing group at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up was lower than that before surgery (all P<0.05). The VAS at 1 and 3 months after surgery and at the last follow-up was lower than those before and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). The differences among VAS of the conventional nursing group before and at 12, 24 hours after surgery were statistically insignificant (all P>0.05). The VAS of the conventional nursing group at 1 and 3 months after surgery and at the last follow-up was lower than those before surgery and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). There was no statistically significant difference in VAS of the two groups between 12 hours and 24 hours after surgery, and between 1 month and 3 months after surgery (all P>0.05). There was no significant difference in the ASIA scores before surgery between the two groups ( P>0.05). There were significant improvements in ASIA scores in the seamless nursing group at 1, 3 months after surgery and at the last follow-up compared with those of the conventional nursing group ( P<0.05). There were no statistically significant differences in preoperative SF-36 score and patient satisfaction score between the two groups (all P>0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were (47.4±6.2)points and (99.5±1.2)points, respectively, which were higher than those of the conventional nursing group [(42.2±7.3)points and (98.1±1.6)points] (all P<0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were higher than those before surgery (all P<0.01). The SF-36 score of the conventional nursing group was higher than that before surgery ( P<0.01), but there was no significant difference in patient satisfaction score ( P>0.05). The incidence of postoperative complications in the seamless nursing group was 6.3% (2/32), lower than that of the conventional nursing group [25.0% (8/32)] ( P<0.05). Conclusion:For AS with kyphosis complicated by cervical spine fracture, whole-process seamless nursing is associated with alleviated postoperative pain, improved spinal nervous function, quality of life and degree of satisfaction, and reduced incidence of complications compared with the conventional nursing.

Objective    To summarize the clinical experience of thoracoscopic combined subsegmentectomy (CSS). Methods    The clinical data of 76 patients who underwent thoracoscopic CSS in Anqing Municipal Hospital from May 2018 to July 2022 were retrospectively analyzed, including 22 males and 54 females, aged 27.0-76.0 (54.3±10.5) years. All patients underwent preoperative three-dimensional computed tomography bronchography and angiography using dual source CT. The modified inflation-deflation technique or indocyanine green was used to identify the intersubsegmental border. Results    A total of 86 pulmonary nodules were resected in 76 patients. One patient of left upper lobe S1+2c+S4a, 1 patient of right upper lobe S2b+S3a and 1 patient of right upper lobe S1b+S3b were further performed lobectomy due to insufficient margin. One patient of left upper lobe S1+2+S3a was further performed left upper division segmentectomy due to residual atelectasis. One patient of left upper lobe S1+2c+S3a was further performed left upper division segmentectomy due to B3b+c injury, and the rest completed planned surgeries successfully. The operative time was 90.0-350.0 (174.9±53.2) min. The operative hemorrhage volume was 50.0 (20.0, 50.0) mL. The postoperative hospital stay time was 6.0 (5.0, 7.0) d. Postoperative complications included pulmonary infection in 9 patients, hemoptysis in 3 patients, persistent pulmonary leakage>3 d in 4 patients, pneumothorax in 1 patient, pleural effusion in 1 patient, and myocardial infarction in 1 patient. All of the patients were cured and discharged without perioperative death. Conclusion    Thoracoscopic CSS is relatively complex. Preoperative planning under three-dimensional reconstruction and intraoperative fine operation are helpful for safe completion.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To analyze the mortality of accidental falls among the elderly in China from 2004 to 2019 and predict the standardized mortality from 2020 to 2024, so as to provide scientific evidence for formulating strategies to prevent accidental falls among the elderly.Methods:The death data of accidental falls of the elderly in China from 2004 to 2019 were collected from the China Death Cause Monitoring Data Set, and the total number of deaths, mortality rate and standardized mortality rate in the elderly from 2004 to 2019 and those data among them of different genders, residences and age groups were calculated. Joinpoint 4.8.0.1 statistical software was used to calculate the annual percent change (APC) and average annual percent change (AAPC) of standardized mortality. The Autoregressive Integrated Moving Average Model (ARIMA) was used to predict the standardized mortality rate of accidental falls among the elderly in China from 2020 to 2024. Results:The number of deaths related to accidental falls among the elderly in China was increased from 2 908 in 2004 to 23 709 in 2019. The mortality rate was increased from 51.89/100 000 in 2004 to 67.74/100 000 in 2019. The standardized mortality rate of accidental falls showed an overall upward trend from 2004 to 2019 (AAPC=1.65, P>0.05), including an upward trend from 2004 to 2010 (APC=1.66, P>0.05), a downward trend from 2010 to 2013 (APC=-9.67, P>0.05), and another upward trend from 2013 to 2019 (APC=7.83, P<0.01). The number of death and mortality rate related to accidental falls in Chinese elderly males and females both showed upward trends from 2004 to 2019, and the standardized mortality rate also showed upward trends from 2004 to 2019 (AAPC males=2.19, AAPC females=0.29, all P>0.05). The standardized mortality rate in males was generally higher than that in females, with that of males showing an upward trend from 2013 to 2019 (APC=7.36, P<0.05) and that of female showing an upward trend from 2014 to2019 (APC=6.92, P>0.05). The number of deaths and mortality rate among the elderly living in rural and urban areas both showed upward trends from 2004 to 2019, and the standardized mortality rate also showed an upward trend from 2004 to 2019 (AAPC rural = 1.71, AAPC urban =1.00, all P>0.05). The standardized mortality rate among the elderly living in rural areas was generally higher than that in urban areas. The rural and urban elderly both showed upward trends from 2013 to 2019 (APC rural = 8.24, APC urban =6.11, all P<0.05). The number of death and mortality rate of different age groups all showed upward trends from 2004 to 2019. The standardized mortality rates of the elderly aged 65-74 years and ≥85 years also showed upward trends from 2004 to 2019 (AAPC 65-74 years=0.38, AAPC ≥ 85 years=4.09, all P>0.05). The standardized mortality rate of the elderly aged 75-84 years showed a downward trend from 2004 to 2019 (AAPC=-0.10, P>0.05), and that of the elderly aged 65-74 years showed an upward trend from 2010 to 2019 (APC=5.35, P<0.05). The standardized mortality rate of the elderly aged 75-84 years and ≥85 years showed upward trends from 2013 to 2019 (APC 75-84 years=6.49, APC ≥ 85 years=10.47, all P<0.05). The ARIMA prediction results showed that the overall standardized mortality rates of accidental falls in the elderly in China from 2020 to 2024 were 69.11/100 000, 72.33/100 000, 74.41/100 000, 76.34/100 000, and 76.48/100 000, respectively, showing a slow upward trend. Conclusions:The accidental fall-related mortality among the elderly in China showed an overall upward trend from 2004 to 2019, and the standardized mortality rate from 2020 to 2024 also shows an upward trend. The elderly who are male in gender, live in rural areas, or at age of ≥85 years are the key population for prevention and control of accidental fall. Active and effective measures should be taken to reduce accidental falls in the elderly so as to contribute to active and healthy aging.
