ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group， with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain， short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group， administered once every other day， with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity， measured using the numerical rating scale （NRS） before and after treatment， and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate， the Eastern Cooperative Oncology Group （ECOG） Performance Status （PS） score， the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire （EORTC QLQ-C30） score， and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests， including routine blood， urine， stool， liver function， and kidney function， were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial， and both groups showed a decrease in average NRS scores and PS scores after treatment， with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group （P＜0.05 or P＜0.01）. After treatment， the NRS change rate in the Qihuang acupuncture group was （0.42±0.17）， significantly higher than that in the control group （0.14±0.27， P＜0.01）. The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group （P＜0.01）. The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30， and a decrease in symptom scores for fatigue， nausea and vomiting， pain， dyspnea， insomnia， appetite loss， constipation， and financial difficulties. In contrast， overall health status and constipation scores in the control group increased， while scores of fatigue， nausea and vomiting， pain， and appetite loss decreased （P＜0.05 or P＜0.01）. After treatment， the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group （P＞0.05）， while the control group showed a significant increase in the 24-hour dose （P＜0.01）. No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study， the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% （1/33）， while the incidence in the control group was 27.27% （9/33） and 36.36% （12/33）， respectively， with the Qihuang acupuncture group showing significantly lower incidence （P＜0.01）. No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life， reduce the dose of opioid analgesics， and has good safety.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To compare the efficacy of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic lumbar compression fracture (OLCF) via the approach through midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach.Methods:A prospective cohort study was conducted to analyze the clinical data of 794 patients with OLCF treated in Honghui Hospital affiliated to Xi′an Jiaotong University School of Medicine from January 2017 to December 2019. The patients were divided into transitional-zone puncture group (400 patients, 400 vertebrae) and pedicle puncture group (394 patients, 394 vertebrae) according to the envelope method. The transitional-zone puncture group was treated with PVP via the approach through midpoint transverse process-transition zone of articular process, and the pedicle puncture group was treated with PVP via the unilateral transpedicular approach. The operation time and radiation dose were documented. The visual analogue score (VAS) and Oswestry dysfunction index (ODI) were evaluated before operation and at 1 day, 3 months, 1 year after operation. The cement distribution and the incidence of complications such as cement leakage, re-fracture of the injured vertebra, spinal cord nerve injury and facet joint injury were detected.Results:The patients were composed of 270 males and 524 females, at the age of 68.9-78.5 years [(73.7±4.8)years]. All patients were followed up for 12-14 months [(13.4±0.8)months]. The operation time and radiation dose in transitional-zone puncture group were reduced compared with pedicle puncture group ( P<0.01). There was no significant difference in VAS and ODI between the two groups before operation (all P>0.05). The VAS between transitional-zone puncture group [(2.1±0.9)points, (2.3±1.1)points, (2.7±1.3)points] and pedicle puncture group [(2.3±0.7)points, (2.5±0.9)points, (2.9±1.1)points] was obviously reduced from that before operation (all P<0.01), significantly different at 1 day, 3 months, 1 year after operation ( P<0.05 or 0.01). The ODI between transitional-zone puncture group (14.3±1.8, 13.6±3.4, 11.3±4.4) and pedicle puncture group (25.5±5.7, 20.7±6.3, 20.6±6.9) was significantly different at 1 day, 3 months, 1 year after operation (all P<0.01), and all were obviously reduced from that before operation (all P<0.01). With regard to the cement distribution, the number of bilaterally cemented vertebrae in transitional-zone puncture group (324) was more than that in pedicle puncture group (94) ( P<0.01). The incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury was 8.25%(22/400), 0.00%(0/400) and 3.25%(13/400) in transitional-zone puncture group, significantly different from 20.81%(82/394), 2.03%(8/394) and 9.90%(39/394) in pedicle puncture group ( P<0.05 or 0.01). There was no significant difference in spinal cord nerve injury between the two groups ( P>0.05). Conclusion:For OLCF, PVP via the approach through the midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach are both effective, but the former has advantages of shorter operation time, smaller radiation dose, greater dispersion of bone cement and lower incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury.

Objective:To compare the clinical efficacies of O-arm combined with CT three-dimensional navigation system assisted screw placement versus manual screw placement in treating lower cervical fracture and dislocation.Methods:A retrospective cohort study was used to analyze the clinical data of 41 patients with lower cervical fracture and dislocation, who were treated in Honghui Hospital, Xi′an Jiaotong University from May 2021 to February 2022. The patients included 26 males and 15 females, aged 31.5-48.6 years [(41.5±15.0)years]. The injured segments were C 3 in 3 patients, C 4 in 12, C 5 in 13, C 6 in 10 and C 7 in 3. Nineteen patients were treated with cervical pedicle screws by O-shaped arm combined with CT three-dimensional navigation system (navigation group, 76 screws) and 22 by bare hands (traditional group, 88 screws). The total operation time, effective operation time, single nail placement time, single screw correction times, screw distance from anterior cortex, intraoperative blood loss, intraoperative fluoroscopic radiation dose, incision length and length of hospital stay were compared between the two groups, and the height of intervertebral space, Cobb angle, interbody slip distance and American Spinal injury Association (ASIA) grade were compared before operation and at 3 days after operation. Visual analogue score (VAS), Japanese Orthopedic Association (JOA) score, and neck dysfunction index (NDI) were evaluated before operation, at 3 days, 3 months after operation and at the last follow-up. Accuracy of screw placement and incidence of complications (adjacent facet joint invasion, infection, screw loosening) were detected as well. Results:All the patients were followed up for 11.1-13.9 months [(12.5±1.4)months]. The total operation time, intraoperative blood loss, intraoperative fluoroscopic radiation dose and incision length in the navigation group were more or longer than those in the traditional group (all P<0.05). The effective operation time, single nail placement time, single nail correction times and screw distance from anterior cortex in the navigation group were markedly less or smaller than those in the traditional group (all P<0.05). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). There were significant improvements in the height of intervertebral space, Cobb angle and interbody slip distance between the two groups at 3 days after operation (all P<0.05). There was no significant difference in the height of intervertebral space, Cobb angle, interbody slip distance or ASIA grade between the two groups before operation or at 3 days after operation (all P>0.05). Compared with pre-operation, the VAS, JOA score and NDI were significantly improved in both groups at 3 days, 3 months after operation and at the last follow-up (all P<0.05), with further improvement with time. There was no significant difference in VAS between the two groups before operation or at 3 months after operation (all P>0.05), but it was markedly lower in the navigation group compared with the traditional group at 3 days after operation and at the last follow-up (all P<0.05). There were no significant differences in JOA score or NDI between the two groups before operation or at 3 days and 3 months after operation (all P>0.05), but both were lower in the navigation group compared with the traditional group at the last follow-up (all P<0.05). The accuracies of placement of grade 0 and grade 0+1 screws were 92.0% (70/76) and 96.6% (73/76) in the navigation group, respectively, which were markedly higher than 88.7% (78/88) and 93.5% (82/88) in the traditional group (all P<0.05). The rates of adjacent facet joint invasion of A, B, and C degrees were 71.2% (54/76), 28.8% (22/76) and 0% (0/76) in the navigation group, respectively, while the invasion rates were 60.5% (53/88), 32.3% (28/88) and 7.3% (7/88) in the traditional group ( P<0.05). No screw loosening was noted in the navigation group, but the screw loosening rate was 9.1% (8/88) in the traditional group ( P<0.01). Conclusion:Compared with manual screw placement, O-arm combined with CT three-dimensional navigation system assisted screw placement for lower cervical fracture and dislocation has the advantages of shorter effective operation time, quicker screw placement, stronger screw holding force, better cervical stability, slighter postoperative pain, higher screw placement accuracy, and lower facet joint invasion and screw loosening rates.

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 investigate the age related changes in cervical range of motion (CROM) and its relationship with cervical spondylosis in school students aged 12-18 in Nanyang City, to provide reference for prevention, early diagnosis and treatment evaluation of cervical spondylosis. Methods: Stratified sampling was adopted in 13 counties and districts of Nanyang City and 890 students aged 12-18 were assessed for CROM using the Coda Motion Analyzer. SPSS 19.0 was used to data analyze. Results: A decreasing trend was observed in CROM among boys and girls aged 12-18 years in Nanyang. For boys aged 15 and 18 years old, higher anterior flexion ( t =2.02, 2.70), posterior extension ( t =2.01, 2.81), left flexion ( t =3.51, 2.99), right flexion ( t =5.07, 2.66), sinistral ( t =2.28, 2.92) and dextral ( t =2.91,3.60) were found compared with younger age groups ( P <0.05). Similar findings were found in girls aged 15 and 18-years old [anterior flexion ( t =2.38, 2.20), posterior extension ( t =2.09,2.02), left flexion ( t =2.33, 2.55), right flexion ( t =7.34, 4.60), sinistral ( t =3.73, 2.35) and dextral ( t =2.31, 3.99, P <0.05). Except for the right flexion, the CROM of boys in was higher than that of girls at the same age group. The prevalence of cervical spondylosis showed an increasing trend (boys: χ 2 trend =13.93, girls: χ 2 trend =12.87, P <0.05). Except for 14-year-old group, the prevalence of cervical spondylosis in girls was higher than that in boys, with significant differences observed in 15 and 17-year-old groups ( χ 2=10.35, 9.64, P <0.05). Conclusion With the increase of age, the CROM of male and female students shows a downward trend in general. The prevalence of cervical spondylosis increases with the decrease of CROM. CROM measurement is conducive to the prevention, early diagnosis and treatment of juvenile cervical spondylosis.

【Objective】 To explore the clinical effect of unilateral double-channel endoscope-assisted bone graft fusion and internal fixation (ULIF) in the treatment of recurrent lumbar disc herniation. 【Methods】 The clinical data of 22 patients with recurrent lumbar disc herniation treated by ULIF in our hospital from August 2020 to October 2020 were analyzed retrospectively. The study indicators included intraoperative blood loss, operation time, bed rest time, and hospital stay. The follow-up data included visual analogue score (VAS) of low back pain, Japanese Orthopaedic Association score (JOA), OSwestry disability index (ODI) score, as well as 36 concise health status survey (SF-36) scores before operation, and 1 week and 6 months after operation. 【Results】 The average operation time was (179.15±42.06) minutes, the average intraoperative blood loss was (132.67±41.92) mL, the average bed rest time was (1.51±0.42) days, and the average hospital stay was (4.82±1.13) days. The VAS score of low back pain at 1 week after operation was lower than that before operation (all P<0.000 1), and further decreased during the follow-up. The ODI score, JOA score and SF-36 score of postoperative follow-up were significantly different from those before operation (P<0.05). The satisfaction rate was 86.4% at 1 week after operation and 95.4% at 6 months after operation. The proportion of significant clinical efficacy at 1 week after operation and postoperative 6 months was 18.2% and 63.6%, respectively. 【Conclusion】 ULIF has the advantages of short-term recovery, less intraoperative blood loss, short bed rest and hospital stay, and good medium-term clinical effect. It is a safe and reliable minimally invasive technique for spinal surgeons in the treatment of recurrent lumbar disc herniation.

Objective:To analyze the incidence and epidemiological characteristics of traumatic spinal cord injury in China in 2018.Methods:Multi-stage stratified cluster sampling was used to randomly select hospitals capable of treating patients with spinal cord injury from 3 regions，9 provinces and 27 cities in China to retrospectively investigate eligible patients with traumatic spinal cord injury admitted in 2018. National and regional incidence rates were calculated. The data of cause of injury，injury level，severity of injury，segment and type of fracture，complications，death and other data were collected by medical record questionnaire，and analyzed according to geographical region，age and gender.Results:Medical records of 4，134 patients were included in this study，with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million （95% CI 50.122-50.846）. The highest incidence in the Eastern region was 53.791 / 1 million （95% CI 53.217-54.365）. In the whole country，the main causes of injury were high falls （29.58%），as well as in the Western region （40.68%），while the main causes of injury in the Eastern and Central regions were traffic injuries （31.22%，30.10%）. The main injury level was cervical spinal cord in the whole country （64.49%），and the proportion of cervical spinal cord injury in the Central region was the highest （74.68%），and the proportion of lumbosacral spinal cord injury in the Western region was the highest （32.30%）. The highest proportion of degree of injury was incomplete quadriplegia （55.20%），and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation，77.95% in the Western region and only 54.77% in the Central region. In the whole country，the head was the main combined injury （37.87%），as well as in the Eastern and Central regions，while the proportion of chest combined injury in the Western region was the highest （38.57%）. A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients （0.56%） died in hospital，of which 17（73.91%） died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury. Other epidemiological features include high fall as the main cause of injury cervical spinal cord injury as the main injury level，incomplete quadriplegia as the main degree of injury，head as the main combined injury，and respiratory complications as the main complication.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
