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.

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 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.

Journal of Peking University(Health Sciences) 2023;55(2):262-269
OBJECTIVE:
To investigate the clinicopathological characteristics of anorectal mucosal melanoma (ARMM), and to evaluate the prognostic factors.
METHODS:
A total of 68 primary ARMM surgical specimens from 2010 to 2018 were retrospectively studied. Slides were reviewed to evaluate pathological features. Slingluff staging method was used for staging.
RESULTS:
(1) Clinical features: The median age at diagnosis in this group was 61.5 years, with a male-to-female ratio 1 ∶1.62. The most common complaint was blooding (49 cases). For anatomic site, anorectum was the prevalent (66.2%), followed by rectum (20.6%). At the time of diagnosis, 28 cases were stage Ⅰ (localized stage, 41.2%), 25 cases were stage Ⅱ (regional lymph node metastasis, 36.8%), and 15 cases were stage Ⅲ (distant metastasis, 22.1%). Five patients underwent wide local excision, the rest abdominoperineal resection, and 48 patients received adjuvant therapy after surgery. (2) Pathological features: Grossly 88.2% of the tumors were exophytic polypoid masses, with the median tumor size 3.5 cm and the median tumor thickness 1.25 cm. Depth of invasion below lamina muscularis mucosae ranged from 0-5.00 cm (median 1.00 cm). The deepest site of tumor invasion reached muscular layer in 27 cases, and perirectal tissue in 16 cases. Melanin pigmentation was absent or not obvious in 67.6% of the cases. The predominant cytology was epithelioid (45 cases, 66.2%). The rate for ulceration, necrosis, lymphovascular invasion, and perineural invasion was 89.7%, 35.3%, 55.9%, and 30.9%, respectively. The median mitotic count was 18/mm2. The positive rate of S100, HMB-45 and Melan-A were 92.0%, 92.6% and 98.0%, respectively. The median of Ki-67 was 50%. The incidences of mutations within CKIT, BRAF and NRAS genes were 17.0% (9 cases), 3.8% (2 cases) and 9.4% (5 cases), respectively. (3) Prognosis: Survival data were available in 66 patients, with a median follow-up of 17 months and a median survival time of 17.4 months. The 1-year, 2-year and 5-year overall survival rate was 76.8%, 36.8% and 17.2%, respectively. The rate of lymphatic metastasis at diagnosis was 56.3%. Forty-nine patients (84.5%) suffered from distant metastasis, and the most frequent metastatic site was liver. Univariate analysis revealed that tumor size (>3.5 cm), depth of invasion below lamina muscularis mucosae (>1.0 cm), necrosis, lymphovascular invasion, BRAF gene mutation, lack of adjuvant therapy after surgery, deep site of tumor invasion, and high stage at diagnosis were all poor prognostic factors for overall survival. Multivariate model showed that lymphovascular invasion and BRAF gene mutation were independent risk factors for lower overall survival, and high stage at diagnosis showed borderline negative correlation with overall survival.
CONCLUSION
The overall prognosis of ARMM is poor, and lymphovascular invasion and BRAF gene mutation are independent factors of poor prognosis. Slingluff staging suggests prognosis effectively, and detailed assessment of pathological features, clear staging and genetic testing should be carried out when possible. Depth of invasion below lamina muscularis mucosae of the tumor might be a better prognostic indicator than tumor thickness.

The metabolites of salvianolic acid A and salvianolic acid B in rats were analyzed and compared by ultra-high-perfor-mance liquid chromatography with linear ion trap-orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS). After the rats were administrated by gavage, plasma at different time points and urine within 24 hours were collected to be treated by solid phase extraction(SPE), then they were gradient eluted by Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) and 0.1% formic acid solution(A)-acetonitrile(B) mobile phase system, and finally all biological samples of rats were analyzed under negative ion scanning mode. By obtaining the accurate relative molecular mass and multi-level mass spectrometry information of metabolites, combined with the characteristic cleavage law of the reference standard and literature reports, a total of 30 metabolites, including salvianolic acid A and B, were identified. Among them, there were 24 metabolites derived from salvianolic acid A, with the main metabolic pathways including ester bond cleavage, dehydroxylation, decarboxylation, hydrogenation, methylation, hydroxylation, sulfonation, glucuronidation, and their multiple reactions. There were 15 metabolites of salvianolic acid B, and the main biotransformation pathways were five-membered ring cracking, ester bond cleavage, decarboxylation, dehydroxylation, hydrogenation, methylation, sulfonation, glucuronidation, and their compound reactions. In this study, the cross-metabolic profile of salvianolic acid A and B was elucidated completely, which would provide reference for further studies on the basis of pharmacodynamic substances and the exploration of pharmacological mechanism.
