OBJECTIVE: To compare the efficacy of percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar fractures. METHODS: A retrospective case-control study was used to analyze the clinical data of 78 patients with osteoporotic thoracic and lumbar fractures admitted from October 2017 to May 2019. According to the surgical method, it was divided into percutaneous pedicle screw combined with unilateral nail placement combined with unilateral bone cement strengthening group(bone cement group) and percutaneous pedicle screw combined with bilateral nail placement(screw group). In the bone cement group, 40 patients included 16 males and 24 females, with a mean age of (62.1±8.1) years old. In the screw group, 38 patients included 18 males and 20 females with a mean age of (65.1±9.3) years old. The operation time, intraoperative blood loss, length of hospital stay and postoperative complications were compared between two groups. The kyphosis Cobb angle, anterior edge height ratio, central height ratio and pain visual analogue score(VAS) were compared. RESULTS: All patients were followed up for 25 to 36 months. The operation time (70.1±17.3) min of the cement group was shorter than that of the screw group (78.6±18.2) min(P<0.05). There were no significant differences in intraoperative blood loss and length of hospital stay(P>0.05). The VAS in the cement group 1 year 1.5±0.5 and the latest follow-up 0.5±0.3 after operation were lower than 1 year 1.8±0.3 and the latest follow-up 0.8±0.4 in the screw group(P<0.05). The kyphosis Cobb angle, anterior edge height ratio, central height ratio in bone cement group, 1 year (6.2±1.2)°, (86.6±3.5)%, (91.1±2.5)%, the last follow-up (6.4±0.7)°, (85.5±3.3)%, (90.5±6.3)% were better than that of the screw group 1 year (6.8±1.4)°, (83.1±2.4)%, (89.9±3.4)% and the latest follow-up (7.1±1.1)°, (82.6±4.1)%, (87.6±5.9)%(P<0.05). There were 3 cases of bone cement leakage in the cement group, all of which had no clinical symptoms;and 2 cases of pedicle screws were extracted in the screw group, and the screws were removed at the last follow-up. CONCLUSION Percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar compression fractures in the elderly can achieve satisfactory efficacy and effectively relieve the pain of patients, but the former internal fixation system is more stable, and the long-term follow-up can effectively maintain the height of the anterior middle column and the correction of kyphosis deformity, and the incidence of chronic low back pain is lower.

OBJECTIVE: To explore early clinical efficacy and advantages of Huoxue Fang's directional dialysis combined with extracorporeal shock wave in treating rotator cuff injury. METHODS: A retrospective analysis was performed for 42 patients with rotator cuff injury admitted from September 2020 to December 2022, and they were divided into shock wave group and directed dialysis group according to different treatment methods. There were 20 patients in shock wave group, including 12 males and 8 females; aged from 47 to 68 years old with an average of (63.2±3.3) years old;the course of disease ranged from 2 to 6 weeks with an average of (3.1±1.4) weeks;10 patients with gradeⅠand 10 patients with gradeⅡaccording to Ellman classification;non-steroidal drugs and extracorporeal shock wave therapy were performed. There were 22 patients in directed dialysis group, including 16 males and 6 females;aged from 44 to 67 years old with an average of (61.0±2.3) years old;the course of disease ranged from 2 to 8 weeks with average of (3.3±1.3) weeks;12 patients with gradeⅠand 10 patients with gradeⅡaccording to Ellman classification;with Huoxue prescription directed transdrug therapy based on shock wave group. Visual analogue scale (VAS), University of California at Los Angeles (UCLA) and range of motion (ROM) were compared between two groups before treatment, 1 and 6 months after treatment;changes of tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1) and interleukin-6 (IL-6) between two groups were detected and compared. The complications between two groups were compared. RESULTS: All patients were followed up, shockwave group followed up for 6 to 8 months with an average of (7.1±1.9) months, 6 to 8 months with an average of (7.2±1.8) months in directed dialysis group, with no statistical significance between two groups (P>0.05). At 1 and 6 months after treatment, VAS in directed dialysis group were (3.85±0.99), (1.24±0.75), which were lower than that in shock wave group (4.91±0.89), (1.81±0.84) (P<0.05). UCLA scores in directed dialysis group (25.25±2.34), (32.71±2.33) were higher than those in shock wave group (21.67±3.38) °, (29.11±3.01) °(P<0.05). Forward bending (139.15±20.39) °, (150.14±20.55) °, external rotation (63.46±16.62) °, (73.35±13.82) °, internal rotation (46.99±2.93) °, (58.24±2.10) ° in directed dialysis group were better than those in shock wave group (130.61±22.27) °, (141.28±19.47) °, external rotation (57.36±17.53) °, (68.12±13.64) °, internal rotation (41.21±3.10) °, (49.16±3.21) ° (P<0.05). At 1 and 6 months after treatment, TNF-α, IL-1 and IL-6 in directed dialysis group were (2.12±0.49), (2.06±0.55), (0.69±0.26) μg·L-1;(1.27±0.25), (1.14±0.23), (0.37±0.11) μg·L-1, which were lower than those in shock wave group (2.87±0. 51), (2.67±0.48), (0.92±0.21) μg·L-1, (1.88 ± 0.26), (1.36±0.27), (0.45±0.09) μg·L-1(P<0.05). At the latest follow-up, 8 patients got excellent result, 10 good and 2 poor in shock wave group;10 patients excellent, 10 good, and 2 poor in directed dialysis group;there was no significant difference between two groups (P>0.05). There were no complications such as skin allergy, subcutaneous hemorrhage, ecchymosis, vascular and nerve injury occurred in both groups. CONCLUSION For the treatment of rotator cuff injury, Huoxue prescription combined with extracorporeal shock wave is effective, which could not only release the local adhesion tissue, improve local blood circulation, accelerate absorption of inflammatory exudate of the local soft tissue, and promote recovery of the diseased muscle bond and ligament. It could also effectively relieve shoulder pain, improve shoulder motion, restore shoulder function, improve patients' quality of life.

OBJECTIVE: To investigate the early clinical efficacy of single-position O-arm navigation-assisted oblique lateral interbody fusion(OLIF) combined with minimally invasive percutaneous pedicle screw fixation(PPS) in the treatment of lumbar spondylolisthesis. METHODS: A retrospective analysis was conducted on 22 patients with lumbar spondylolisthesis who underwent OLIF-PPS surgery including 11 males and 11 females with a mean age of (64.6±1.5) years old ranging from 49 to 80 years old between April 2021 and June 2023. All patients presented with lumbosacral pain, lower limb radiating pain, numbness, and had poor responses to conservative treatment. Surgical time, intraoperative blood loss, hospital stay, and postoperative complications were recorded. Clinical outcomes were evaluated using the visual analogue scale(VAS) and Oswestry disability index(ODI) preoperatively at 3 days after operation and the final follow-up. Standing lumbar anteroposterior and lateral X-rays were performed to measure disc height(DH), slippage degree, vertebral reduction rate, pedicle screw accuracy, and cage subsidence. RESULTS: All surgeries were successfully completed with a mean follow-up of (27.1±2.2) months (range 18 to 36 months). The mean surgical time was (76.1±12.2) min (range 60 to 93 min), intraoperative blood loss was (86.3±32.2) ml (range 40 to 113 ml), and hospital stay was (7.1±1.2) days. Postoperative VAS significantly improved from (7.2±0.7) preoperatively to (2.3±0.5) at 3 days after operation and (1.7±0.2) at the final follow-up (P<0.05). ODI decreased from (68.5±7.2)% preoperatively to (30.3±3.1)% at 3 days after operation and (16.6±1.6)% at the final follow-up (P<0.05). DH increased from (8.5±1.7) mm preoperatively to (18.1±1.4) mm at 3 days after operation and (17.2±1.1) mm at the final follow-up (P<0.05). Slippage degree improved from (24.1±4.6)% preoperatively to (10.3±4.2)% at 3 days after operation and (10.1±3.2)% at the final follow-up (P<0.05). A total of 88 pedicle screws were implanted with an excellent rate of 98% (86/88). Complications included transient left hip flexion weakness (2 cases) and left anteromedial thigh pain (1 case), all resolved during follow-up. No incision hematoma, infection, screw loosening, or cage subsidence occurred. CONCLUSION Single-position O-arm navigation-assisted OLIF combined with PPS demonstrates satisfactory early clinical efficacy for lumbar spondylolisthesis, with advantages including minimal invasiveness, significant pain relief, effective vertebral reduction, and low complication rates.

OBJECTIVE: To explore the efficacy and safety of human epidermal growth factor gel in the treatment of pin tract infections after surgery in patients with severe spinal deformity. METHODS: A retrospective case-control study was conducted to analyze the clinical data of 26 patients with pin tract infections after skull-pelvic ring traction for severe spinal deformity admitted from February 2019 to May 2022. Among them, 11 were male and 15 were female;the age ranged from 18 to 31 years, with an average of (24.1±4.3) years;the Cobb angle ranged 80.3° to 120.7°, with an average of (88.6±10.2)°;there were 52 iliac traction pins, 104 pin tract openings, and 38 pin tract infections. According to the Checketts-Otterbum classification, there were 11 infections of gradeⅠ, 13 infections of gradeⅡ, 10 infections of grade Ⅲ, and 4 infections of grade Ⅳ. The patients were divided into the conventional dressing change group (13 cases) and the growth factor group (13 cases) by coin flipping. Clinical efficacy was evaluated by recording the visual analogue scale(VAS) score during dressing change, duration of dressing change, cost of dressing change, positive rate of bacterial culture, wound improvement rate, and wound improvement time. RESULTS: There were no statistically significant differences in VAS or duration of dressing change between the two groups (P>0.05). The cost of dressing change was (800.0±59.5) yuan in the conventional dressing change group and (1 179.5±80.9) yuan in the growth factor group, with a statistically significant difference (P<0.05). There was no statistically significant difference in the positive rate of bacterial culture between the two groups (P>0.05). In the conventional dressing change group, within 20 pin tract infections, 2 infections achieved wound healing, 7 infections showed improvement, and 11 infections were ineffective;in the growth factor group, within 18 pin tract infections 5 infections achieved wound healing, 8 infections showed improvement, and 5 infections were ineffective, with a statistically significant difference between the two groups (P<0.05). The wound healing time was (22.8±4.9) days in the conventional dressing change group and (14.2±2.5) days in the growth factor group, with a statistically significant difference (P<0.05). No complications occurred in either group. CONCLUSION The application of human epidermal growth factor gel in the treatment of pin tract infections after skull-pelvic ring surgery in patients with severe spinal deformity is easy to operate, does not increase patient pain, and has significant efficacy. It shortens wound healing time, effectively promotes wound healing, and has good safety and high cost-effectiveness.

OBJECTIVE: To evaluate the association between erectile dysfunction (ED) and myocardial infarction (MI) using two sample Mendelian randomization. METHODS: A Mendelian randomization study was conducted using comprehensive data on ED and MI from extensive genome-wide association data. Using inverse variance weighted analysis for causal relationships, and correct for confounding factors using multivariate Mendelian randomization, the potential mediating effects were evaluated as well. Based on Genecard data, the genes related to ED and MI were identified. Molecular docking was used to reveal spontaneously bound drug molecules. RESULTS: Our study found that exposure to ED was a risk factor for MI (OR: 1.001 0, 95% CI: 1.000 2－1.001 8, P=0.017 7), which also held true in the validation dataset (OR: 1.028 5, 95% CI: 1.005 0－1.052 6, P=0.017 2). No statistically significant heterogeneity or horizontal pleiotropy was found. The results of reverse Mendelian randomization analysis showed any reverse causal relationship between ED and MI. In multivariate Mendelian randomization analysis, after excluding confounding factors (excluding triglycerides and high-density lipoprotein), the P-value remained less than 0.05, and the OR ranged from 1.000 1 to 1.000 7, indicating that ED was still a risk factor for MI. In the mediation analysis, it was found that the current mediation ratio of smoking to MI was 13.06%. In summary-data-based mendelian randomization analysis, it was found that the gene PTPN11 was a common target gene for MI and ED (OR=0.990, P<0.001). Subsequent molecular docking with sildenafil, clopidogrel, and dapoxetine could spontaneously bind to the PTPN11 gene receptor. CONCLUSION There is a causal relationship between ED and MI, with smoking as a potential mediating factor, and the gene PTPN11 being a co-target gene.

ObjectiveTo study the relationship between qi stagnation constitution and suboptimal health status (SHS) or lifestyle.MethodsFrom 2012 to 2013, we conducted a cross-sectional survey of 24 159 Chinese individuals aged 12–80 years. The qi stagnation constitution was assessed using the Constitution in Chinese Medicine Questionnaire. Health status was evaluated through medical records and the Subhealth Measurement Scale V1.0 (SHMS V1.0). Health-promoting lifestyles were measured using the Health-Promoting Lifestyle Profile II (HPLP-II).ResultsOf the 24 159 participants, 16.1% and 15.2% were classified as “always” and “sometimes” having the qi stagnation constitution, respectively. Those classified as “rarely” having the qi stagnation constitution scored higher on both the HPLP-II and SHMS V1.0. The participants classified as “always” having the qi stagnation constitution showed a significant association with SHS or disease compared to other imbalanced constitutions. Those in the “always” category were approximately 21 times more likely to be classified as having SHS (odds ratio [OR]: 21.17, 95% confidence interval [CI]: 15.74–28.45), whereas those in the “sometimes” category were approximately six times more likely (OR: 5.89, 95% CI: 5.04–6.90). Accordingly, the qi stagnation constitution score was significantly associated with the diagnosis of SHS, with an area under the curve of 0.77 (P .001). A score of 18.75 yielded the highest Youden Index (0.407), with a sensitivity of 60.5% and a specificity of 80.3%. Significant associations were observed between health-promoting lifestyles and qi stagnation constitution severity in an ordinal regression analysis (P .001). Protective factors included stress management (OR: 1.59), self-actualization (OR: 1.57), and exercise (OR: 1.36). In contrast, poorer interpersonal relationships (OR: 0.79), greater health responsibilities (OR: 0.86), and poorer nutrition (OR: 0.91) were associated with increased severity.ConclusionModulating the qi stagnation constitution through lifestyle interventions may help prevent the progression of SHS to disease, which aligns with core preventive principles in traditional Chinese medicine.

OBJECTIVE To investigate the relationship between the course of antibiotics during perioperative period and postoperative infection in pregnant women with human immunodeficiency virus/acquired immune deficiency syndrome(HIV/AIDS) undergoing cesarean section, and to guide the rational use of antibiotics in clinical practice. METHODS A total of 53 cesarean section women in the hospital from January 2014 to September 2022 were chosen as research objects. According to the course of antibiotics, the puerperae were divided into two groups. The treatment course of antibiotics in the study group(n=31) was >24 h and ≤48 h, and the control group(n=22) was ≤24 h. The postoperative wound healing, inflammatory indexes, postoperative infection rate, and postoperative hospital stay were observed. RESULTS There was no significant difference in postoperative body temperature, white blood cell count, neutrophil ratio, C-reactive protein, postoperative hospital stay, wound healing grade and postoperative infection rate between the study group and the control group. CONCLUSION Antibiotics for HIV/AIDS patients during perioperative period of cesarean section for <24 h may play a better role in preventing postoperative infection.

OBJECTIVE: To observe the early clinical efficacy of the zero-remember cervical Solis fusion device in the treatment of adjacent segment degeneration(ASD) revision after anterior cervical discectomy and fusion(ACDF). METHODS: A retrospective analysis was performed for 13 patients with adjacent spondylosis after anterior cervical discectomy bone graft fusion with Solis fusion device, including 5 males and 8 females, aging from 56 to 78 years old. The patients had intractable neck pain or superficial paresthesia of upper extremities before operation, and the effect of conservative treatment was not good. The operation time, intraoperative blood loss and postoperative complications were recorded. Before operation, 1 week postoperative and final follow-up, the visual analogue scale(VAS) and Japanese Orthopaedic Association(JOA) scores were used to assess clinical efficacy. X-ray and CT of the cervical spine were performed to measure and evaluate the height of the intervertebral space and intervertebral fusion. RESULTS: All patients were followed up from 18 to 36 months. All 13 patients successfully completed revision surgery with single gaps. The operation time was 63 to 93 min, the intraoperative blood loss was 15 to 83 ml. The pain VAS was reduced from 4 to 7 points before surgery to 1 to 3 points at 1 week and 1 to 2 points at the final follow-up. The height of the intervertebral space was increased from 5.2 to 7.2 mm before surgery to 6.4 to 8.0 mm at 1 week after surgery and 6.4 to 7.9 mm at the final follow-up. The JOA score was increased from 11 to 17 points before surgery to 13 to 17 points at 1 week after surgery and 16 to 17 points at the final follow-up visit. At the final follow-up, AP and lateral X-ray films of cervical spine showed homogeneous bone fusion of the Solis fusion. One patient developed transient left upper limb weakness after surgery, which recovered at follow-up, and all patients had no dysphagia, incision hematoma or infection, and displacement. CONCLUSION The early clinical efficacy of Solis fusion device in the treatment of orthospondylosis after anterior cervical intervertebral fusion is satisfactory, and it has the advantages of less surgical trauma, adequate decompression, high osseointegration rate and fewer complications, which can provide a new option for minimally invasive treatment of orthospondylosis after cervical spine surgery.

Objective To evaluate the effect of donor age on short-term survival of patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 235 IPF donors and recipients of lung transplantation were retrospectively analyzed. Univariate and multivariate Cox proportional hazard regression models were employed to analyze the correlation between donor age and short-term mortality rate of IPF patients after lung transplantation. Kaplan-Meier was used to draw the survival curve. Results Univariate Cox regression analysis showed that donor age was correlated with the 1-year fatality of IPF patients after lung transplantation. The 1-year fatality of recipients after lung transplantation was increased by 0.020 times if donor age was increased by 1 year (P=0.009). Oxygenation index of the donors, preoperative oxygenation index, preoperative lung allocation score, preoperative N-terminal pro brain natriuretic peptide, pattern of transplantation, pattern of intraoperative extracorporeal membrane oxygenation and intraoperative blood transfusion volume of the recipients were correlated with 1-year fatality after lung transplantation (all P < 0.1). Multivariate Cox regression analysis demonstrated that there was no correlation between donor age and 30-, 90-, 180-d and 1-year fatality of IPF patients after lung transplantation (all P > 0.05). Sensitivity analysis showed that there was no significant difference in 30-, 90-, 180-d and 1-year fatality after lung transplantation among donors aged < 18, 18-33, 34-49 and ≥50 years (all P > 0.05). Conclusions Donor age exerts no effect upon short-term survival of IPF patients after lung transplantation. Considering the mechanical ventilation time, oxygenation index, infection and other factors of donors, the age range of lung transplant donors may be expanded.

OBJECTIVE: To explore risk factors for infections after arthroscopic rotator cuff repair, and improve the under standing for reducing infection. METHODS: Clinical data of 2 591 patients who underwent arthroscopic rotator cuff repair from January 2019 to January 2022 were retrospectively analyzed, including 1 265 males and 1 326 females, aged from 25 to 82 years old with an average age of (51.5±15.6) years old. They were divided into infection group(n=18) and uninfected group(n=2 573) according to whether or not patients had postoperative infection. Gender, age, smoking, diabetes, body mass index, local closure within 1 month before operation, operation time, preventive use of antibiotics, and internal fixation implantation between two groups were recorded. Univariate Logistic regression analysis screened factors associated with infections after arthroscopic rotator cuff repair. Theresultswere entered into the multivariate logistic regression analysis, screening the high risk factors for infections after arthroscopic rotator cuff repair. RESULTS: In 2 591 patients, 18 patients were infected after operation, infection rate was 0.69%. Univariate Logistic regression analysis showed that gender, age, operation time, antibiotic prophylaxis, internal fixation implantation were risk factors for infections after arthroscopic rotator cuff repair. Multivariate Logistic regression analysis showed male(OR=14.227), age≥65 years(OR=34.313), operation time≥2 h (OR=15.616), without antibiotic prophylaxis(OR=4.891), and internal fixation implantation(OR=5.103) were major risk factors for infection after arthroscopic rotator cuff repair(P<0.05). CONCLUSION Male, age≥65 years, operation time≥2 h, without antibiotic prophylaxis and internal fixation implantation were independent risk factors for infection after arthroscopic rotator cuff repair. Early diagnosis and timely treatment should be carried out to reduce the incidence of infection.
