Serum alkaline phosphatase (ALP) has long been used as a biomarker for the liver, kidney, and bone. Currently, increasing evidence suggests a correlation between serum ALP and cardiovascular disease (CVD). Research has shown that serum ALP affects endothelial cell function and induces changes in pyrophosphate through various mechanisms to accelerate vascular calcification and promote cardiac fibrosis. Therefore, this article reviews the potential value of serum ALP in CVD through relevant research, revealing the specific relationship between serum ALP and CVD, in order to provide new ideas for the prevention and treatment of CVD.
Objective To study the clinical effects of laparoscope combined with choledochoscope in patients with cholecystolithiasis and choledocholithiasis. Methods Clinical data of 74 patients with cholecystolithiasis and choledocholithiasis between Mar. 2009 and Feb. 2011 in our hospital were retrospectively analyzed. Among them， 37 cases underwent the laparoscope combined with choledochoscope operation （referred to as the double mirror operation group） and 37 cases underwent the conventional open operation （open operation group）. The intraoperative conditions， therapeutic effect， and complications of patients in 2 groups were compared. Results The stone clearance rates of the two groups were 100%. The recurrence rate of 2 groups in the follow-up process was no significantly difference （P＞0.05）. In the double mirror operation group， the operative time was significantly longer than that open operation group （P＜0.01）；the intraoperative bleeding was significantly less than that open operation group （P＜0.01）；the anal exhaust time after operation， get out of bed time after operation， and total duration of hospitalization were significantly shorter than that open operation group （P＜0.01）；and the incidence of postoperative complications was significantly lower than that open oper-ation group（P＜0.01）. Conclusion Laparoscope combined with choledochoscope in treatment of cholecystolithiasis and choledocholithiasis patients has exact effects， with minor trauma， quicker recovery， and fewer complications， and it’s worthy of promotion.
Objective To investigate the effectiveness of transplanting iliac bone flap with deep iliac circumflex vessels and cancellous bone for the treatment of adult avascular necrosis of the femoral head (ANFH). Methods A retrospective analysis was made on the clinical data of 685 patients (803 hips) with ANFH, who underwent iliac bone flap transplantation with deep iliac circumflex vessels and cancellous bone between March 2002 and January 2010. There were 489 males (580 hips) and 196 females (223 hips) with a mean age of 40.4 years (range, 18-63 years), including 567 unilateral cases (303 left hips and 264 right hips) and 118 bilateral cases. The causes of ANFH included alcohol-induced in 223 cases, steroid-induced in 179 cases, alcohol + steroid-induced in 21 cases, traumatic in 136 cases, acetabular dysplasia in 8 cases, bone cyst in 5 cases, septic arthritis in 2 cases, joint tuberculosis in 3 cases, rheumatoid arthritis in 5 cases, and idiopathic in 103 cases. According to Steinberg staging, 211 hips were rated as stage II, 513 hips as stage III, and 79 hips as stage IV. The preoperative Harris hip score was 60.30 ± 7.02. Results Fat necrosis occurred in 2 cases after operation, primary healing of incision was obtained in the other cases; delayed infection, lower extremity deep vein thrombosis, and pulmonary embolism occurred in 2 cases, respectively. All patients were followed up 36-60 months (mean, 49 months). Harris hip score at last follow-up (83.50 ± 7.31) was significantly higher than that at preoperation (t= — 2 266.980, P=0.000), and the scores were significantly higher than those at preoperation in different stages (P lt; 0.05). The results were excellent in 523 hips, good in 185 hips, fair in 65 hips, and poor in 30 hips, and the excellent and good rate was 88.2%. X-ray examination showed bone fusion of transplanted bone flap and bone graft with an average of 4.2 months (range, 3-6 months); according to Steinberg staging, imaging stable rate was 78.3% (629/803) at last follow-up. Conclusion Iliac bone flap transplantion with deep iliac circumflex vessels and cancellous bone has the advantages of complete decompression of the femoral head, exact flap blood supply, improved blood supply of the femoral head, new support for the femoral head, and participation of osteoinductive effect for the treatment of adult ANFH, so it is an effective treatment for the retention of the femoral head.
Objective To evaluate the functional and aesthetic evaluation of external fixator lengthening through plantar approach for fourth brachymetatarsia. Methods A retrospective analysis was conducted on 20 patients (23 feet) with fourth brachymetatarsia who met the selection criteria between January 2016 and January 2024, including 3 males and 17 females, with 8 left, 9 right, and 3 bilateral cases. The mean age was 24.7 years (range, 14-51 years). The preoperative metatarsal shortening length was (13.8±3.2) mm. The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score was 79.5±3.9, the visual analogue scale (VAS) score of appearance satisfaction was 1.7±0.8, and the appearance index (AI) score was 13.6±0.9. All patients underwent external fixator lengthening through plantar approach. The lengthening length of metatarsal bone, lengthening ratio, healing time, and healing index were recorded. Functional outcomes were assessed using the AOFAS forefoot score, VAS score of appearance satisfaction, and quality-of-life impact with AI questionnaire. Results All 20 patients were followed up 14-55 months with an average of 36.3 months. During the follow-up, complications occurred in 4 cases (17.4%), including 2 cases of metatarsophalangeal joint stiffness, which had no significant effect on the function and appearance. Delayed union of osteotomy occurred in 1 case (healed at 12 weeks after operation). Pin loosening occurred in 1 case and recovered after outpatient reinforcement. No complications related to plantar scar occurred. At last follow-up, the lengthening length of metatarsal bone was (13.9±3.1) mm, and the lengthening ratio was 25.8%±5.6%. All cases achieved bony union, with a mean healing time of (64.3±12.5) days and a healing index of (46.9±4.8) d/cm. At last follow-up, AOFAS score was 98.9±2.1, the VAS score of appearance satisfaction was 9.3±0.7, and the AI score was 0.6±0.8, which significantly improved when compared with those before operation (t=27.398, P<0.001; t=32.994, P<0.001; t=56.135, P<0.001). Conclusion External fixator lengthening through plantar approach is a safe and effective technique for fourth brachymetatarsia, achieving satisfactory functional and aesthetic outcomes.
ObjectiveTo evaluate the long-term efficacy and influencing factors of cervical artificial disc replacement (CADR) for patients with cervical spondylotic radiculopathy (CSR).MethodsThe data of 29 CSR patients who underwent Bryan artificial disc replacement between December 2003 and December 2007 and followed up more than 10 years were retrospectively analysed. There were 16 males and 13 females with an average age of 54.1 years (range, 40-70 years). The disease duration was 2-144 months (mean, 19.2 months). CT and MRI were performed before operation to identify the compression segments (C3, 4 in 2 cases, C4, 5 in 6 cases, C5, 6 in 18 cases, C6, 7 in 3 cases) and the compression factors. According to the compression factor, the patients were divided into 2 groups: 14 patients with cervical disc herniation were in the group A and 15 patients combined with osteophyte were in the group B. There was no significant difference in gender, age, disease duration, and compressed level between 2 groups (P>0.05). The radiographic and clinical evaluation indexes were recorded before operation and at last follow-up. The radiographic evaluation indexes included the global cervical and segmental range of motion (ROM), loss of ROM (ROM<3°) at last follow-up, Cobb angle and incidence of local kyphosis, paravertebral ossification (PO) grading. The clinical evaluation indexes included neck disability index (NDI) and overall efficacy (Odom’s score).ResultsAll patients were followed up 121-153 months (mean, 130 months). The results of radiographic evaluation indexes showed that within group comparison, except that the Cobb angle of the operated level was significantly decreased (P<0.05) in both 2 groups, there was no significant difference in global cervical ROM and segmental ROM between preoperation and last follow-up (P>0.05). Except that the loss of ROM (ROM<3°) at last follow-up and high-grade PO at last follow-up in group B were significantly higher than those in group A (P<0.05), there was no significant difference in other radiographic evaluation indexes between 2 groups (P>0.05). The results of clinical evaluation indexes showed that the NDI was significantly improved in both groups (P<0.05) at last follow-up. There was no significant difference in the NDI at preoperation and at last follow-up, the decline of NDI at last follow-up, and the overall efficacy evaluated by Odom’s score between 2 groups (P>0.05). The excellent and good rate of overall efficacy reached 100% in both groups.ConclusionCADR has satisfied long-term efficacy in treating CSR. The maintenance of segmental mobility was better in patients with disc herniation than in patients with disc herniation and osteophyte.
Objective To analyze the correlation between postoperative complications and combined deflection angle classification adduction type (CDAC-ADT) of femoral neck fractures after cannulated screw internal fixation. MethodsThe clinical data of 121 patients with CDAC-ADT femoral neck fracture admitted between January 2018 and December 2021 and met the selected criteria were retrospectively analyzed. There were 69 males and 52 females, the age ranged from 19 to 79 years (mean, 48.1 years). The causes of injury included 52 cases of traffic accident, 24 cases of falling from height, and 45 cases of fall. The time from injury to operation ranged from 2 to 12 days, with an average of 6.0 days. Among them, there were 18 cases of CDAC-ADT type Ⅰ, 46 cases of type Ⅱ, and 57 cases of type Ⅲ; 6 cases of Garden type Ⅱ, 103 cases of type Ⅲ, and 12 cases of type Ⅳ; and according to the location of the fracture line, there were 26 cases of subcapitate type, 88 cases of transcervical type, and 7 cases of basal type. All patients were treated with cannulated screw internal fixation. The occurrence of complications (including internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head) was recorded, and the correlation between complications and CDAC-ADT typing, Garden typing, and fracture line location were analyzed. Results The patients were followed up 8-44 months, with a mean of 24.9 months. There were 10 cases of internal fixation failure, 7 cases of fracture nonunion, and 30 cases of osteonecrosis of the femoral head after operation. Correlation analysis showed that patients’ CDAC-ADT typing was significantly correlated with the overall incidence of complication and the incidence of internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head (P<0.05), and the Pearson coefficient of contingency were 0.435, 0.251, 0.254, and 0.241, respectively. Garden typing did not correlate with the overall incidence of complication and the incidence of internal fixation failure and fracture nonunion (P>0.05), but correlated with the incidence of osteonecrosis of the femoral head (P<0.05), and the Pearson coefficient of contingency was 0.251. Fracture line position typing had no correlation with the overall incidence of complication and the incidence of internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head (P>0.05). Conclusion CDAC-ADT typing has obvious correlation with postoperative complications of femoral neck fracture and can be used to predict complications of femoral neck fracture.
ObjectiveTo evaluate the influence of the shell angle of cervical artificial disc on long-term effectiveness of cervical artificial disc replacement (CADR).MethodsThe clinical data of 71 patients who were treated with single-level CADR with Bryan prosthesis between December 2003 and December 2007 and followed up more than 10 years, were retrospectively analyzed. There were 44 males and 27 females with an age of 26-69 years (mean, 45.9 years). According to the shell angle of the cervical artificial disc which was measured on the postoperative lateral X-ray film, the patients were divided into kyphotic group (shell angle was negative) and non-kyphotic group. The following evaluation indexes before operation and at last follow-up were compared between 2 groups. Radiographic indexes included the range of motion (ROM) of cervical spine, the ROM of operated level, Cobb angle of operated level (the negative value indicated that the segmental kyphosis occurred at operated level), paravertebral ossification (PO) grades (grades 3 and 4 were high grade PO). Clinical indexes included Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), and overall effectiveness evaluation (Odom criteria).ResultsThere were 24 patients in kyphotic group and 47 patients in non-kyphotic group. There was no significant difference in baseline data including gender, age, and operated level between 2 groups (P>0.05). All the patients in 2 groups were followed up 121-165 months (mean, 128 months). There was no significant difference in preoperative ROM of cervical spine and ROM of operated level between 2 groups (P>0.05); but the preoperative Cobb angle of operated level in kyphosis group was significantly lower than that in non-kyphotic group (t=2.636, P=0.013). There was no significant difference in ROM of cervical spine at last follow-up between 2 groups (t=1.393, P=0.168), however, the ROM and the Cobb angle of operated level in kyphotic group were significantly lower than those in non-kyphotic group (P<0.05). According to the Cobb angle of operated level at last follow-up, there were 9 patients (37.5%) with segmental kyphosis in kyphotic group and 7 patients (14.9%) in non-kyphotic group, showing significant difference (χ2=4.651, P=0.031). There was a significant difference in PO grades between 2 groups (Z=2.894, P=0.004) at last follow-up. In kyphotic group, there were 10 patients (41.7%) with low grade PO and 14 patients (58.3%) with high grade PO; and in non-kyphosis group, there were 36 patients (76.6%) with low grade PO and 11 patients (23.4%) with high grade PO. There was no significant difference in JOA scores and NDI before operation and at last follow-up, and the JOA improvement rate, NDI decline, and Odom criteria score at last follow-up between 2 groups (P>0.05).ConclusionThe shell angle of cervical artificial disc may lead to a decrease in the postoperative segmental ROM, and an increased occurrence of segmental kyphosis and high incidence of PO.
Objective To systematically review the impact of cardiac shock waves on coronary artery disease. Methods The PubMed, Cochrane Library, Wed of Science, EMbase, ClinicalTrials.gov, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect randomized controlled trials and cohort studies related to the treatment of coronary artery disease with cardiac shock waves from inception to August 2022. After two evaluators independently screened the literature, extracted data, and evaluated the risk of bias of the included studies, a meta-analysis was conducted by using RevMan 5.4.1 and Stata 15.0 software. Results A total of 11 studies with 519 patients were included. The meta-analysis results revealed that compared with the control group, cardiac shock wave therapy could reduce hospitalization rates (RR=0.38, 95%CI 0.25 to 0.57, P<0.01), increase exercise time (SMD=0.93, 95%CI 0.17 to 1.70, P=0.02), and improve the Canadian Cardiovascular Society (CCS) angina grading (MD=−0.62, 95%CI −0.73 to −0.51, P<0.01), the New York Heart Association (NYHA) cardiac function grading (MD=−0.60, 95%CI −0.85 to −0.35, P<0.01), left ventricular ejection fraction (MD=4.81,95%CI 3.17 to 6.46, P<0.01), total score of the Seattle angina questionnaire (SAQ) (MD=10.87, 95%CI 4.63 to 17.12, P<0.01), and 6-min walking test (MD=85.06, 95%CI 31.02 to 139.09, P<0.01). Conclusion Cardiac shock wave therapy can improve cardiac function as well as the prognosis and exercise ability. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
