OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective:To explore the surgical intervention strategy for metastatic cervical lymph nodes surrounding the carotid artery in head and neck squamous cell carcinoma.Methods:A total of 62 patients with advanced head and neck tumors and carotid wrap by disease treated in Department of Otorhinolaryngology and Head and Neck Surgery, the Affiliated BenQ Hospital of Nanjing Medical University between June 2019 and December 2023 were reviewed, of whom 9 patients presented with metastatic squamous cell carcinoma in cervical lymph nodes of unknown primary or with no recurrence of primary lesion and all the 9 patients were males, aged from 48 to 79 years old, with≤level 2 of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS). Radiographically common carotid artery (CCA) and/or internal carotid artery (ICA) were surrounded by≥270° with tumor. All the 9 patients received implantation of covered stent in carotid artery and radical resection of metastatic cervical lymph nodes. The success rate, complications, surgery-related complications, local recurrence rate, quality of life (QOL) and overall survival (OS) were analyzed. The QOL of patients was compared by paired rank sum test, and P<0.05 indicated statistically significant difference. The OS was analyzed by Kaplan-Meier. Results:The success rate of stent implantation was 100%, with no implantation-related complications. R0 resection was performed in 8 cases and R1 resection in 1 case. The QOL of patients after surgery was improved, and the improvements in "pain", "mood" and "anxiety" were statistically significant( Z values were -2.236, -2.460 and -2.200, respectively, and all P values were<0.05). Follow-up was 1-18 months, with a median of 7 months, and 1 case was lost to follow-up. Local recurrence occurred in 3 patients with an incidence of 37.5% (3/8). OS was 59.9% at 12 months after surgery. Conclusion:Implantation of covered stent in carotid artery combined with radical resection is an effective method for the treatment of cervical lymph node metastasis.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

Background Improper settings of outdoor smoking points in public places may increase the risk of secondhand smoke exposure among the population. Conducting research on air pollution in and around smoking spots and related influencing factors can provide valuable insights for optimizing the setting of outdoor smoking points. Objective To investigate the influence of the number of smokers at outdoor smoking points and the distance on the diffusion characteristics of surrounding air pollutants, in order to optimize the setting of outdoor smoking points. Methods Surrounding the exhibition halls in the China International Import Expo (CIIE), two outdoor smoking points were randomly selected, one on the first floor (ground level) and the other on the second floor (16 m above ground), respectively. At 0, 3, 6, and 9 m from the smoking points in the same direction, validated portable air pollutant monitors were used to measure the real-time fine particulate matter (PM_2.5) and carbon dioxide (CO₂) concentrations for consecutive 5 d during the exhibition, as well as the environmental meteorological factors at 0 m with weather meters including wind speed, wind direction, and air pressure. An open outdoor atmospheric background sampling point was selected on each of the two floors to carry out parallel sampling. Simultaneously, the number of smokers at each smoking point were double recorded per minute. The relationships between the number of smokers, distance from the smoking points, and ambient PM_2.5 and CO₂ concentrations were evaluated by generalized additive regression models for time-series data after adjustment of confounders such as temperature, relative humidity, and wind speed. Results The median numbers of smokers at smoking points on the first and second floors were 6 [interquartile range (IQR): 3, 9] and 9 (IQR: 6, 13), respectively. Windless (wind speed <0.6 m·s⁻¹) occupied most of the time (85.9%) at both locations. The average concentration of ambient PM_2.5 at the smoking points (0 m) [mean ± standard deviation, (106±114) μg·m⁻³] was 4.2 times higher than that of the atmospheric background [(25±7) μg·m⁻³], the PM_2.5 concentration showed a gradient decline with the increase of distance from the smoking points, and the average PM_2.5 concentration at 9 m points [(35±22) μg·m⁻³] was close to the background level (1.4 times higher). The maximum concentration of CO₂ [(628±23) μmol·mol⁻¹] was observed at 0 m, and its average value was 1.3 times higher than that of the atmospheric background [(481±40) μmol·mol⁻¹], and there was no gradient decrease in CO₂ concentration with increasing distance at 0, 3, 6, and 9 m points. The regression analyses showed that, taking smoking point as the reference, every 3 m increase in distance was associated with a decrease of ambient PM_2.5 by 24.6 [95% confidence interval (95%CI): 23.5, 25.8] μg·m⁻³ (23.2%) and CO₂ by 54.1 (95%CI: 53.1, 55.1) μmol·mol⁻¹ (8.6%). Every one extra smoker at the smoking point was associated with an average increase of PM_2.5 and CO₂ by 2.0 (95%CI: 1.7, 2.8) μg·m⁻³ and 1.0 (95%CI: 0.7，1.2) μmol·mol⁻¹, respectively. The sensitivity analysis indicated that, under windless conditions, the concentrations of PM_2.5 and CO₂ at the smoking points were even higher but the decreasing and dispersion characteristics remained consistent. Conclusion Outdoor smoking points could significantly increase the PM_2.5 concentrations in the surrounding air and the risks of secondhand smoke exposure, despite of the noticeable decreasing trend with increasing distance. Considering the inevitable poor dispersion conditions such as windless and light wind, outdoor smoking points are recommended to be set at least 9 m or farther away from non-smoking areas.

Objective:To explore the clinical value of a trinity strategy for the treatment of multiple orthopedic trauma.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 267 patients with multiple orthopedic trauma admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the First Affiliated Hospital of Navy Medical University from June 2013 to May 2023, including 862 males and 405 females, aged 18-93 years [(55.2±19.8)years]. Associated injuries included hemorrhagic shock in 632 patients, traumatic wet lung in 274, cranial injuries in 135, abdominal and pelvic bleeding in 116, pneumothorax in 89, urinary injury in 13, and vesical rupture in 8. All the patients were treated with the trinity strategy and the treatment process was divided into the phases of first aid, remodeling, and rehabilitation. The first aid phase focused on stabilizing symptoms and saving lives; the remodeling phase centered on restoring the anatomical structure and alignment; the rehabilitation phase aimed for functional recovery through the integration of both Western and traditional Chinese medicine. The all-cause mortality within 30 days after surgery and fracture healing time were calculated; the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, Hospital for Special Surgery (HSS) knee score and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at the last follow-up and the overall excellent and good rate of all joint function scores were measured. The short form health survey (SF-36) scores were collected preoperatively and at 6 months postoperatively, including 8 aspects such as physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The incidence of postoperative complications was recorded.Results:All the patients were followed up for 6-18 months [(10.2±4.2)months]. The mortality rate during the acute phase (within 30 days after surgery) was 2.37% with 12 deaths due to hemorrhagic shock, 10 due to traumatic brain injury, 6 due to multiple organ dysfunction syndrome (MODS), and 2 due to pulmonary infection. The average fracture healing time averaged 3.8-18 months [(11.5±4.2)months], with 89.49% of the patients having bone union within 12 months after surgery, 8.93% having bone union within 18 months after surgery, and 1.58% undergoing reoperation. For the patients with internal fixation failure and nonunion, the average healing time was extended to (10.2±2.2)months and (13.7±3.3)months respectively. At the last follow-up, the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, HSS knee score, and AOFAS ankle-hindfoot score were 83.93%, 90.24%, 94.12%, 85.57%, 88.46%, and 92.31% respectively, with an overall excellent and good rate of 89.11%. At 6 months after surgery, the SF-36 scores of all the patients in the eight dimensions,including the physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health were (74.4±8.6)points, (44.7±14.4)points, (77.4±10.9)points, (68.4±18.2)points, (72.5±16.0)points, (76.8±8.7)points, (49.9±17.6)points, and (72.8±17.9)points, significantly improved compared with those before operation [(63.4±12.7)points, (30.9±17.4)points, (56.4±18.0)points, (55.4±24.7)points, (53.5±21.0)points, (55.8±24.3)points, (36.9±24.0)points, (58.8±21.6)points] ( P<0.01). Complications of different degrees occurred in 214 patients (16.89%), including lung infections in 118 patients (9.31%), lower extremity deep vein thrombosis in 50(3.95%), pressure injuries in 26(2.05%), internal fixation failure in 12(0.95%), and nonunion in 8(0.63%). Conclusions:The trinity strategy provides whole-process management, personalized treatment, and overall rehabilitation for multiple orthopedic trauma. It can decrease mortality, shorten fracture healing time, improve joint function and quality of life, and reduce the incidence of complications.

Streptococcus parasuis(S.parasuis)is a close relative of S.suis and can cause meningi-tis,pneumonia or systemic symptoms in affected animals.In this paper,the dominant strain was i-solated from diseased pigs with pneumonia in Jilin,China,and the isolated strain was identified as S.parasuis by 16S rRNA,it was named WYF-8B.Resistance was tested by the susceptibility tablet diffusion method,and WYF-8B was resistant to bacitracin,sulfamethoxoprim,lincomycin,erythro-mycin,fosfamycin,azithromycin,penicillin,doxycycline,cotrimotrixazole,sulfamisoxazole,cipro-floxacin,enrofloxacin,tetracycline,benzoxacillin,gentamicin,efazolin,and ampicillin.It was highly sensitive to florfenicol,chloramphenicol.Iochemical identification revealed that WYF-8B could fer-ment salicylic acid,maltose,lactose,sucrose,oxaesin,and glucose;nonfermentable mannitol,urea,raffinose,xylose,arabinose,and sorbitol.Using the second-generation whole-genome sequencing technology to study the WYF-8B resistant genotype,it was found that it carried the macrolide anti-biotic resistance genes Mef(E)and ErmB;resistance genes pbp2b,pbp1a,and pbp2x to β-lactam antibiotics;resistance genes gyrA,parC,and grlB to fluoroquinolones;resistance genes ANT(6)-Ia,AAC(6')-Ie-APH(2')-Ia,ANT(9)-Ia,APH(3')-Ⅲa to aminoglycoside antibiotics;re-sistance groups lnuB,lmrC,lmrD against lincomide antibiotics;resistance gene tetM to tetracy-cline antibiotics;the resistance gene of bacitracin,bcrA.The results found that the resistance phe-notype matches the resistance genotype of the sequencing results.The study of WYF-8B virulence factors found that WYF-8B carried 13 virulence factors(pavA,fbp 54,clpP,cps 4,cps 4 I,wbtB,cps,sI,tufA,galE,hasC,groEL,wrbtL,wbbtF),which mainly acted to promote bacterial diffu-sion,transfer,settlement,antiphagocytosis and immune evasion.The results of drug sensitivity test provide a reference for the study of clinical medication of S.parasuis,and drug resistance pheno-type and virulence factors lay the foundation for the research and development of new drugs and vaccines.

【Objective】 To evaluate and analyze the impact of COVID-19 epidemic on inventory of red blood cells (RBCs)in local and municipal blood stations in China, and to provide reference for the management of public health emergencies. 【Methods】 Relevant data from 2018 to 2021 were collected, and the differences in the volume of qualified RBCs, the usage efficiency of inventory RBCs, the average daily distribution of RBCs,the blood distribution rate of RBCs prepared by 400 mL whole blood, the difference in the average storage days of RBCs at the time of distribution, the average daily inventory of RBCs and the time of the average daily inventory of RBCs to maintain the distribution in 24 local and municipal blood stations in China during the COVID-19 epidemic and non-epidemic periods were retrospectively analyzed. 【Results】 Compared with non-epidemic periods, the volume of qualified RBCs [(117 525.979 ±52 203.175)U] and the average daily distribution of RBCs [( 156. 468 ± 70. 186) U ] increased significantly, but the usage efficiency of inventory RBCs decreased(97.24%±0.51%) significantly (P<0.05).There was no significant difference in the blood distribution rate of RBCs prepared by 400 mL whole blood(73.88%±20.30%), the average storage days of RBCs distribution(13.040 ±3.486), the average daily stock quantity of RBCs[(2 280.542 ±1 446.538) U ] and the time of the average daily inventory of RBCs to maintain the distribution[(15.062 ±7.453) d] (P>0.5). 【Conclusion】 During the COVID-19 epidemic, the inventory management of RBCs operated well, the overall inventory remained relatively stable, the stock composition and storage period showed no significant change.

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 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.
