ABSTRACT

Objective:To investigate the effectiveness of the modified Bikini approach in the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate.Methods:A retrospective study was conducted to analyze the data of 54 patients with acetabular fracture who had been treated at Department of Trauma Orthopedics, Orthopedic Medical Center, The Third Hospital Affiliated to Southern Medical University from May 2017 to June 2021. The patients were divided into 2 groups based on different surgical approaches: an observation group [26 cases, 6 males, 20 females; aged 40.0 (29.8, 46.8) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the modified Bikini approach, and a control group [28 cases, 10 males, 18 females; aged 34.5 (24.0, 43.5) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the lateral-rectus approach. The incision length, operation time, intraoperative bleeding, length of hospital stay, quality of postoperative fracture reduction, visual analog scale (VAS) for pain, hip function, Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) were compared between the 2 groups.Results:The differences in the preoperative general data between the 2 groups were not statistically significant, indicating comparability ( P>0.05). There were no statistically significant differences between the 2 groups either in terms of incision length, operation time, intraoperative bleeding, or hospital stay ( P>0.05). The 2 groups were not significantly different in the excellent/good rate of fracture reduction [100.0% (26/26) versus 92.9% (26/28)], VAS at 1 month postoperation [2.0(1.0, 3.0) versus 2.0(1.0, 3.0)], or the modified Merle d'Aubigné and Postel hip score at 12 months postoperation [13.5(12.3, 14.8) versus. 14.0(13.0, 15.0)] ( P>0.05). However, the VSS [4.50(4.00, 6.00)] and POSAS (29.85±10.05) at 12 months postoperation in the observation group were significantly lower than those in the control group [6.50(5.00, 8.25) and 37.11±11.75] ( P<0.05). Conclusion:In the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate, the modified Bikini approach can not only achieve as fine early clinical efficacy as the lateral-rectus approach, but also demonstrate the aesthetic advantages of smaller incision scar and more hidden incision.

ABSTRACT

ObjectiveTo establish a rat model of diabetic wound by feeding on a high-fat and high-sugar diet combined with intraperitoneal injection of streptozotocin (STZ) and surgical preparation of full-thickness skin defects, observe the effect of cinnamaldehyde on the wound healing of diabetes rats, and explore the therapeutic mechanism of cinnamaldehyde in improving wound healing of diabetes rats based on the PTEN-induced putative kinase (PINK1)/Parkin pathway-mediated mitochondrial autophagy. MethodForty-eight male SD rats were randomly divided into blank group (n=12) and diabetes group (n=36). The diabetes group was further randomly divided into model group, cinnamaldehyde group, and Beifuxin group, with 12 rats in each group. The blank group and the model group received routine disinfection with physiological saline after creating the wounds, while the cinnamaldehyde group received topical application of polyethylene glycol 400 (PEG 400) gel containing 4 μmol·L-1 cinnamaldehyde, and the Beifuxin group received topical application of Beifuxin gel. Dressings were changed once daily. The wound healing rate of each group was observed. On the 7th and 14th days after intervention, the wound tissues of the rats were collected. Hematoxylin and eosin (HE) staining was performed to observe the pathological changes in the local tissues. Immunohistochemistry (IHC) was used to detect the expression of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), vascular endothelial growth factor (VEGF), and collagen fibers. Immunofluorescence (IF) and Real-time polymerase chain reaction (Real-time PCR) were used to detect the protein, and mRNA expression of PINK1, Parkin, microtubule-associated protein 1 light chain 3 Ⅱ (LC3 Ⅱ). ResultAfter intraperitoneal injection of STZ, compared with the blank group, the random blood glucose values of rats in the diabetic group increased significantly (P<0.01), all higher than 16.7 mmol·L-1, and persistently hyperglycemic for some time after modeling. Compared with the blank group, the model group showed poor growth and healing of granulation tissue in the wounds, and the wound healing rate decreased (P<0.01). On the 7th day after intervention, the blank group had squamous epithelial coverage on the wounds. Compared with the blank group, the model group only had a small amount of scab at the wound edges, with a large number of infiltrating inflammatory cells in the wounds. The protein expression levels of IL-6 and TNF-α in the tissues increased (P<0.01), and the protein and mRNA levels of PINK1, Parkin, and LC3Ⅱ decreased (P<0.01). On the 14th day after the intervention, the granulation tissue in the wounds of the blank group was mature and well-healed. Compared with the blank group, the model group still had infiltrating inflammatory cells and red blood cell exudation. The protein expression levels of VEGF and collagen fibers in the tissues decreased (P<0.01), and the protein and mRNA expression levels of PINK1, Parkin, and LC3Ⅱ increased (P<0.01). Compared with the model group, the cinnamaldehyde group and the Beifuxin group showed better wound healing, with increased wound healing rates (P<0.01). On the 7th day after intervention, the protein expression levels of IL-6 and TNF-α in the tissues decreased (P<0.01), and the protein and mRNA expression levels of PINK1, Parkin, and LC3Ⅱ increased (P<0.01). On the 14th day after intervention, the protein expression levels of VEGF and collagen fibers in the tissues increased (P<0.01), and the protein and mRNA expression levels of PINK1, Parkin, and LC3Ⅱ decreased (P<0.01). ConclusionCinnamaldehyde can promote the wound healing of diabetes rats by increasing the wound healing rate, reducing the levels of inflammatory factors IL-6 and TNF-α, and increasing the levels of VEGF and collagen fibers. Its mechanism may be related to the regulation of the PINK1/Parkin signaling pathway, activation of mitochondrial autophagy, inhibition of inflammatory responses, and promotion of angiogenesis and collagen synthesis, thereby promoting the wound healing of diabetes rats.

ABSTRACT

Objective:To explore the surgical methods and treatment effects of adult anterior dislocation of the sacroiliac joint (AADSJ).Methods:A multi-center retrospective case series study was conducted to analyze the clinical data of 25 cases admitted in 5 clinical centers (affiliations of authors in this article) from January 2016 to January 2021. There were 18 males and 7 females, aged 38.8±15.5 years (range, 18-83 years). The AADSJ clinical classification system was formulated based on the radiographic morphology of anterior dislocation of the sacroiliac joint, which includes two types. Type I: complete anterior dislocation of the sacroiliac joint, and displacement of the entire iliac auricular surface to the front of the sacrum. Type II: fracture of the sacroiliac joint combined with anterior dislocation, subdivided into 3 subtypes. Type IIa: iliac fracture involves the anterior 1/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIb: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIc: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anteromedial to the sacrum. The reliability and repeatability of the clinical classification, Tile classification and Young-Burgess classification were performed based on the results of two-phase assessments in four observers. The operations were performed by the lateral-rectus approach and the ilioinguinal approach. The operation time and intraoperative bleeding were recorded. Pelvic X-ray and CT scan were rechecked after the operation. The quality of fracture reduction was evaluated according to Matta score. The postoperative functional rehabilitation was evaluated according to the Majeed rehabilitation standard at one-year follow-up.Results:Among 25 cases in this study, there were 3 cases of Type I, 5 cases of Type IIa, 9 cases of Type IIb and 8 cases of Type IIc according to the clinical classification system. The Kappa values of reliability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.681, 0.328 and 0.383, respectively. The Kappa values of repeatability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.690, 0.221 and 0.395, respectively. The reliability and repeatability of the AADSJ clinical classification were significantly better than other classifications. There were 14 cases underwent lateral rectus abdominis approach and 11 cases underwent ilioinguinal approach. The operative time for managing anterior dislocation of the sacroiliac joint was 122.0±50.7 min (range, 65-148 min) through the lateral rectus abdominis approach, and through the ilioinguinal approach was 178.0±49.9 min (range, 110-270 min), with a significant difference ( t=2.76, P=0.011). The amount of intraoperative blood loss through the lateral rectus approach was 680±330 ml (range, 350-2,120 ml), which was significantly less than that through the ilioinguinal approach (1,660±968 ml, 680-3,300 ml), with a significant difference ( t=3.55, P=0.002). The follow-up period was 1-3 years. At one week after surgery, the quality of fracture reduction evaluated by Matta score showed that the excellent and good reduction rate of the lateral-rectus approach was 79% (11/14), and that of the ilioinguinal approach was 73% (11/14), with no statistically significant difference ( P=1.000). At a one-year follow-up, according to Majeed's criteria, the overall excellent and good rate of the lateral-rectus approach was 64% (9/14), which is similar to 64% (7/11) of that of the ilioinguinal approach. No fracture reduction loss or internal fixation loosening failure occurred. Conclusion:The AADSJ clinical classification system can accurately describe the imaging features and clinical manifestations of AADSJ, with high reliability and repeatability. The AADSJ can be treated by the lateral-rectus approach or the ilioinguinal approach, with similar therapeutic effects but the former having less trauma.

ABSTRACT

Objective:To investigate the surgical method of LC-II screws for fragility fractures of the pelvis (FFP) in the elderly and evaluate its clinical efficacy.Methods:A retrospective analysis was performed on 45 patients with FFPs operated in our department from January 2011 to January 2022. The clinical information was as follows. The FFP classification of pelvic fracture was IIIA in 26 cases and IIIB in 19 cases. Among them, 22 cases were fixed with closed reduction and modified LC-II screws (experimental group), and 23 cases were fixed with open reduction and reconstruction plates (control group). In the experimental group, there were 6 males and 16 females. The age range was 62-90 years, with an average of 73.2±9.2 years. The FFP classification of pelvic fracture was IIIA in 12 cases and IIIB in 10 cases. In the control group, there were 8 males and 15 females. The age range was 60-87 years, with an average of 72.8±6.6 years. FFP classification of pelvic fracture was IIIA in 14 cases and IIIB in 9 cases. After admission, pelvic X-ray and CT scan were performed, and the surgery was prepared. In the experimental group, after closed reduction of the posterior ring, the modified LC-II screw was inserted below the anterior inferior iliac spine (AIIS) toward the sacroiliac joint and penetrated the sacroiliac joint. For combined anterior ring fractures, the INFIX was used for anterior ring fixation. In the control group, the posterior ring was fixed with a reconstruction plate and/or sacroiliac screw after open reduction through the lateral rectus approach (LRA). The clinical efficacy was evaluated between the experimental group and the control group.Results:All 45 patients were successfully operated and followed up for 6 months to 3 years. All the pelvic fractures healed. In the experimental group of 22 cases, the time from injury to operation was 3-9 days, with an average of 5.8±1.9 days; the operation time was 25-70 min, with an average of 42.0±12.9 min. The intraoperative bleeding was 20-40 ml, with an average of 29.1±6.7 ml. According to the X-ray reduction evaluation criteria of Matta, 7 cases were excellent, 11 cases were good and 4 cases were medium, with an excellent and good rate of 81.8%. According to rehabilitation criteria of Majeed, 10 cases were excellent, 6 cases were good and 6 cases were fair, with a total excellent and good rate of 72.7%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 10 cases, <3 in 7 cases, and 4-6 in 5 cases. No internal fixation loosening occurred. In the control group, the time from injury to operation was 5-20 days, with an average of 9.9±3.8 days; the operation time was 50-150 min, with an average of 89.1±29.5 min; the intraoperative bleeding was 220-1 000 ml, with an average of 509.2±214.3 ml. According to the X-ray reduction evaluation criteria of Matta, 16 cases were excellent, 4 cases were good and 3 cases was medium, with an excellent and good rate of 87.0%. According to rehabilitation criteria of Majeed, 12 cases were excellent, 6 cases were good and 7 cases were fair, with a total excellent and good rate of 78.3%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 14 cases, <3 in 6 cases, and 4-6 in 3 cases. In the control group, posterior ring plate loosening was found in 2 cases and anterior ring pubic ramus plate and screw loosening was found in 4 cases, but there was no reduction loss.Conclusion:The modified LC-II screw is theoretically feasible in the treatment of FFP. Preliminary clinical results show good safety and efficacy, providing a new idea for minimally invasive treatment of FFP.

ABSTRACT

Objective:To investigate the efficacy of intelligent visualization system (HoloSight Intelligent Visualization System) assisted reduction and screw fixation in the treatment of elderly pelvic fragility fracture.Methods:From January 2016 to December 2022, clinical data of 18 elderly patients aged over 75 years with pelvic fragility fractures surgically treated by our team were retrospectively analyzed. Among them, 11 cases were treated with closed reduction and hand-inserted percutaneous screw fixation to fix the posterior pelvic ring (control group), and 7 cases were treated with the assistance of the HoloSight intelligent visualization system for reduction and minimally invasive fixation (experimental group). In the control group, there were 3 males and 8 females with an age range of 75-94 years (mean age, 82±12 years). The pelvic fractures were classified as FFP type IIIa in 5 cases, IIIb in 2 cases, IIIc in 3 cases, and IV in 1 case. In the experimental group, there were 1 male and 6 females with an age range of 76-100 years (mean age. 83±14 years). The pelvic fractures were classified as FFP type IIIa in 4 cases, IIIc in 2 cases, and IV in 1 case. The surgical time, blood loss, effective intraoperative fluoroscopy times, fracture reduction quality (according to Matta standards), visual analogue scale (VAS), limb function rehabilitation (Majeed score) and postoperative complications were recorded and evaluated in both groups.Results:All patients underwent surgery successfully and were followed up for 6 months to 3 years(12 months on average), all pelvic fractures healed. Among the 7 cases of experimental group, a total of 13 screws were placed, and the adjustment times of guide pin for each screw were 3±1 times (range, 1-5 times), while 18 screws of the control group with the adjustment times of 7±2 times (range, 4-10 times), statistical difference was present ( t=6.99, P<0.001). The surgical time in experimental group (63±12 min) was shorter than that in control group 88±23 min, while effective intraoperative fluoroscopy times in experimental group (9±3 times) was less than that in control group (35±7 times), the difference were both statistically significant ( t=2.69, P=0.016; t=9.22, P<0.001). The intraoperative blood loss was 38±12 ml in the experimental group and 55±26 ml in control group, with no significant difference ( t=1.61, P=0.127). According to Matta's reduction criteria after surgery, the results of experimental group were excellent in 4 cases, good in 2, and fair in 1, while the result of control group were excellent in 5 cases, good in 3, fair in 2, and poor in 1. At the last follow-up, among the patients in experimental group, the Majeed score was 84±11, excellent in 3 cases, good in 2, and fair in 2. In control group, the score was 79±17, with excellent in 5 cases, good in 3, fair in 3. No statistical difference was observed in two groups ( t=0.69, P=0.501). The VAS was 6.4±2.6 preoperatively and 2.4±0.8 postoperatively in the experimental group, while in the control group was 6.9±3.1 preoperatively and 2.7±1.3 postoperatively, the data suggested an improvement in both groups ( t=3.89, P=0.002; t=4.14, P<0.001), while no statistical significant was observed in two groups at last follow-up ( t=0.55, P=0.593). Two cases of experimental group had loosening or withdrawal of the fixation screws in 9 and 12 months, but the fractures healed. Four cases of control group loose fixation screws in 4, 6, 9, and 12 months, two cases underwent revision surgery and other two cases healed. Conclusion:Intelligent visualization system assisted reduction and screw fixation in the treatment of elderly pelvic fragility fractures have the advantages of good reduction, accurate nail placement, less bleeding, less effective fluoroscopy, which improves the safety of surgery.

ABSTRACT

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

ABSTRACT

Objective:To investigate the clinical efficacy of integrated acetabular wing-plate in the management of both column fractures with posterior wall involvement via the lateral-rectus approach.Methods:A retrospective case series analysis was performed on 43 patients with both column fractures involved with posterior wall admitted to Third Affiliated Hospital of Southern Medical University from March 2016 to June 2020. There were 35 males and 8 females, aged 19-78 years [(47.3±13.3)years]. The single lateral-rectus approach was used to expose, reduce and fix the fracture using the integrated acetabular wing-plate. Operation time, incision length, intraoperative blood loss and bone healing time were recorded. Quality of fracture reduction was assessed according to the Matta reduction criteria at postoperative 2 days, and hip function by the modified Merle d′Aubigné-Postel score at postoperative 3 months and 12 months. Postoperative complications were observed.Results:All patients were followed up for 12-48 months [(28.1±13.1)months]. Operation duration was 35-150 minutes [(84.6±26.3)minutes], with incision length of 8-12 cm [(9.4±1.0)cm] and intraoperative blood loss of 100-1 200 ml [(200(300, 500) ml]. Bone healing time was 3-6 months [(3.9±0.9)months]. According to Matta reduction criteria,the results were excellent in 32 patients, good in 7 and poor in 4 at postoperative 2 days, with the excellent and good rate of 91%. The modified Merle d′Aubigné-Postel score was 12-18 points [(16.1±1.5)points] at postoperative 3 months, and 13-18 points [(17.3±1.2)points] at postoperative 12 months ( P<0.01). According to modified Merle d′Aubigné-Postel score, the results were excellent in 3 patients, good in 34 and fair in 6 at postoperative 3 months, with the excellent and good rate of 86%; and the results were excellent in 32 patients, good in 9 and fair in 2 at postoperative 12 months, with the excellent and good rate of 95% ( P<0.01). Postoperative complications were incision fat liquefaction and infection in 1 patient, weakness of hip adduction in 5 and screw loosening with traumatic arthritis in 1. There was no sciatic nerve injury or heterotopic ossification. Conclusion:For both column fractures with posterior wall involvement, single lateral-rectus approach combined with integrated acetabular wing-plate has advantages of short operation time, minor trauma, low rate of bleeding and complications, and good hip function recovery, indicating satisfactory clinical effect.

ABSTRACT

Objective:To compare the clinical efficacy of lateral-rectus approach and ilioinguinal approach in the treatment of Torode-Zieg type IV pelvic fracture in toddlers.Methods:A retrospective cohort study was used to analyze the clinical data of 12 toddlers with Torode-Zieg type IV pelvic fracture admitted to Affiliated Hospital of Youjiang Medical College for Nationalities and Third Affiliated Hospital of Southern Medical University from June 2012 to June 2019. There were 6 males and 6 females, aged 13-36 months [(23.9±7.4)months]. Treatment via ilioinguinal approach was performed for 5 patients (ilioinguinal group), and via lateral-rectus approach for 7 patients (lateral-rectus group). Operation duration, intraoperative blood loss and postoperative complications were compared between the two groups. At the last follow-up, pelvic function was evaluated by Majeed function score, and fracture reduction was evaluated according to Mears-Velyvis radiological evaluation criterion.Results:All patients were followed for 24-72 months [(46.0±18.5)months]. In ilioinguinal group and lateral-rectus group, the operation time was (295.0±95.3)minutes and (165.1±52.2)minutes, respectively ( P<0.05), and the intraoperative blood loss was (190.0±65.2)ml and (225.7±92.0)ml, respectively ( P>0.05). In ilioinguinal group, the development of bilateral iliac wings was asymmetric in 3 patients. In lateral-rectus group, fracture-dislocation of epiphyseal plate together with abnormal development of iliac wing occurred in 1 patient, but had no effects on the function of lower limbs. According to Majeed function score at the last follow-up, the pelvic function in ilioinguinal approach group was rated as excellent in 1 patient, good in 2, fair in 1 and poor in 1, with the excellent and good rate of 60%, while the pelvic function in lateral-rectus group was excellent in 4 patients, good in 1, fair in 2 and poor in none, with the excellent and good rate of 71% ( P>0.05). According to Mears-Velyvis radiological evaluation criterion at the last follow-up, the fracture reduction in ilioinguinal group was rated as satisfied in 3 patients and dissatisfied in 2 patients, with the satisfaction rate of 60%, while the fracture reduction in lateral-rectus group was satisfied in 7 patients and dissatisfied in none, with the satisfaction rate of 100% ( P>0.05). Conclusions:For Torode-Zieg type IV pelvic fracture in toddles, both surgical approaches can complete the reduction and fixation. However, the lateral-rectus approach has shorter operation time and less damage to the epiphyseal structure around the pelvis than the ilioinguinal approach.

ABSTRACT

Objective:To explore the surgical techniques and clinical effects of minimally invasive adjustable plate (MIAP) together with distraction reduction by minimally invasive anterior pelvic ring internal fixator (INFIX) in the treatment of fresh Denis type ⅡB sacral fracture with sacral nerve injury.Methods:From June 2017 to June 2020, 12 fresh Denis type ⅡB sacral fractures were treated by anterior-posterior distraction reduction and fixation with MIAP and INFIX. There were 8 males and 4 females, with an average age of 30 years (from 16 to 44 years). Preoperatively, imaging found Denis ⅡB fracture of the sacrum and magnetic resonance neurography of the lumbosacral plexus showed injury to the sacral nerve root at the sacral foramen. All patients had symptoms of S 1 nerve root injury on the affected side after injury, with 9 cases of grade M0 and 3 cases of grade M1. The time from injury to operation averaged 11 days (from 5 to 19 days). INFIX combined with MIAP was used to distract and fixate the compressed sacral fracture. The quality of fracture reduction and recovery of sacral nerve function were evaluated postoperatively. Results:According to the criteria proposed by Lindahl et al., the quality of fracture reduction was excellent in 8 cases, good in 2 and fair in 2. The 12 cases were followed up for an average of 20 months (from 12 to 36 months). All sacral fractures got united after an average of 6 weeks (from 5 to 8 months). At one-year follow-up, according to the criteria proposed by the Nerve Injuries Committee of the British Medical Research Council, the postoperative muscle strength recovery was evaluated as complete recovery in 10 cases and as partial recovery in 2 cases.Conclusion:In the treatment of fresh Denis type ⅡB sacral fracture, MIAP combined with INFIX can obtain satisfactory clinical effects because the compressed sacrum can be effectively distracted, the sacral foramen be expanded and the sacral nerve be decompressed indirectly.

ABSTRACT

Objective:To investigate the clinical effect assistant with pelvic unlocking reduction frame for the treatment of old Denis I or II sacral fractures combined with sacral plexus nerve injury.Methods:From January 2013 to October 2020, 37 patients diagnosed with old sacral fractures with sacral plexus nerve injury which Gibbons classification was grade III were divided into the use group and the non-use group according to whether assisted with pelvic unlocking reduction frame. Eighteen patients (11 males, 7 females, mean age 38±6.4, range from 13-56) were selected into the use group and nineteen patients (14 males, 5 females, mean age 42±10.7, range 19-59) were selected into the non-use group. The three-dimensional (3D) pelvic model (1∶1) was printed before operation. The operation time, intraoperative bleeding, Matta score, visual analogue scale (VAS), Majeed score and gibbons sacral nerve injury grade of the two groups were compared. The healing time and complications of each group was recorded.Results:The average operation time of the use group and the non-use group was 121.0±16.2 min and 182.6±16.2 min, respectively, with significant difference ( t=11.54, P<0.001). The mean operative bleeding was 686±382 ml of the use group and 963±348 ml of the non-use group ( t=2.38, P=0.003). The quality of fracture reduction was evaluated according to Matta scoring standard: the excellent and good rate of the use group was 94% (17/18), and that of the non-use group was 68% (13/19) ( P=0.039). The curative effect was evaluated according to the Majeed score: the use group was 88.72±7.03 points, and that of the non-use group was 72.00±9.75 points ( t=5.96, P<0.001) at 1 year post-operative. One year after operation, the VAS scale of the use group was 0.83±0.71 points, and that of the non-use group was 1.00±0.82 points ( t=0.66, P=0.512). According to Gibbons classification, 15 patients were grade I, 1 patient was grade II and 2 patients were grade III in the use group and 11 patients were grade I, 3 patients were grade II and 5 patients were grade III in the non-use group one year after operation ( Z=-1.04, P=0.401). One patient in the use group presented rupture of plate without symptoms. In the non-use group, 1 case with internal iliac vein rupture which treated with gelatin sponge and no obvious bleeding after operation. 4 cases with unequal length of lower limbs, walking claudication. The complication rate of the use group was 6% (1/18), and that of the non-use group was 26% (5/19) ( P=0.042) . Conclusion:The lateral rectus abdominis approach combined with pelvic unlocking reduction frame can reduce the operation time and bleeding, improve the fracture reduction in the treatment of old Denis type I and II sacral fractures with sacral plexus injury.

ABSTRACT

Objective:To explore the surgical technique and clinical results of the lateral-rectus approach (LRA) for acetabular fractures combined with ipsilateral greater sciatic notch fractures.Methods:Nine cases of acetabular fractures combined with ipsilateral greater sciatic notch fractures treated by the LRA from January 2015 to January 2021 were involved in this study, including 7 males and 2 females with age of 39.8±15.4 years (range, 25-54 years). Six cases were injured by falling and the others by traffic accidents. There were 3 cases combined with pelvic fractures, 1 combined with craniocerebral injury, 3 combined with thoracic injury, 2 combined with closed abdominal injury, and 3 combined with other fractures of the extremities. Based on the Letournel-Judet classification, the cases were all classified as double-column acetabular fractures. The fractures of the greater sciatic notch are all fractures with obvious displacement from the lower part of the sacroiliac joint through the top of the greater sciatic notch to the posterior column of the acetabulum. Pelvic X-ray and CT examination were performed after operation. The reduction quality of the acetabulum and greater sciatic foramen was evaluated by Matta's criteria. The function of the hip joint was assessed by modified Merle D'Aubigné-Postel score.Results:All 9 patients were successfully completed the operation, and followed up. The operation time was 140.4±55.2 min (range, 110-190 min). The amount of intraoperative blood loss was 770.5±430.9 ml (range, 540-1,260 ml). All cases of fractures had healed in 7.7±3.4 weeks (range, 6-12 weeks) after operation. According to Matta's reduction quality criteria, the quality of fracture reduction after surgery was excellent in 7 cases and good in 2 cases. The follow-up period was 24.8±8.8 months (range, 6-12 months). Fractures of the acetabulum and greater sciatic foramen healed well, with the healing time of 6 to 12 weeks. There were no complications such as loss of fracture reduction, failure of internal fixation, traumatic arthritis or necrosis of femoral head. Matta's modified Merle d'Aubigne-Postel hip function score was 16.2±0.6 (range, 12-18) one year after surgery. There were excellent in 6 cases, good in 2 cases, fair in 1 case, with an excellent and good rate of 89%.Conclusion:Fractures of the acetabulum and ipsilateral greater sciatic notch are serious injuries with difficulty in surgical reduction and fixation. The LRA can better complete reduction and fixation of the above fractures, obtaining satisfactory clinical outcomes.

ABSTRACT

Objective:To investigate the safety and clinical efficacy of the lateral-rectus approach combined with the Pfannenstiel approach in the treatment of pelvic fractures complicated with urethral rupture.Methods:From January 2013 to June 2021, 20 patients with pelvic fracture complicated with urethral rupture were surgically managed through the lateral-rectus approach and the Pfannenstiel approach at Department of Traumatic Surgery, Center for Orthopaedic Surgery, the Third Hospital Affiliated to Southern Medical University. They were 15 males and 5 females, with an average age of 42 years (from 18 to 55 years). By the Tile classification, there were 11 cases of type B and 9 cases of type C. The first-stage urethral realignment was performed via the Pfannenstiel approach in the supine position after general anesthesia in conjunction with an urologist; at the second-stage, the lateral-rectus approach was used to reduce and fixate the acetabular or pelvic fractures. The operation time, intraoperative blood loss, fracture reduction quality, pelvic functional recovery and complications were documented.Results:In this cohort, the operation time ranged from 80 to 240 min, averaging 140.5 min; the time for simple urethral convergence ranged from 20 to 30 min; the intraoperative blood loss ranged from 400 mL to 2,000 mL, averaging 730 mL. According to the Mears andVelyvis evaluation for fracture reduction quality, anatomical reduction was achieved in 13 cases, satisfactory reduction in 6 cases, and unsatisfactory reduction in one. The 20 patients were followed up for 12 to 68 months (mean, 37 months) after surgery. One fracture got nonunited but the other fractures got united after 3.0 to 4.5 months (mean, 3.5 months). According to the Majeed scoring system, the pelvic function at 12 months after surgery was excellent in 12 cases, good in 6 and fair in 2, giving an excellent and good rate of 90% (18/20). Screw loosening was found in one patient, traction injury to the lumbosacral trunk nerve in another patient, varying degrees of dysuria which responded to periodic urethral dilation in 8 patients, urethral stricture in 3 patients and erectile dysfunction in 5 patients. No abdominal hernia or pelvic infection was observed.Conclusions:The lateral-rectus approach combined with the Pfannenstiel approach can be used effectively to reduce and fixate the pelvic and acetabular fractures, and to repair the urethral rupture in one stage as well. They are also safe due to a low incidence of such complications as abdominal wall hernia and pelvic infection.

ABSTRACT

Objective:To explore the effects of aerobic exercise combined with resistance exercise on patients with diabetic peripheral neuropathy (DPN).Methods:A total of 60 patients with DPN in Sixth Affiliated Hospital of Nantong University from June 2018 to October 2019 were selected, and randomly divided into control group (20 cases), aerobic exercise group (20 cases) and combined training group (20 cases). Three groups all received the routine medication management and dietary guide. The control group had no other intervention. The aerobic exercise group received moderate intensity cycle ergometer, 40 min/time, once a day, three times a week. In addition to the moderate intensity aerobic exercise, patients in the combined training group conducted resistance exercise with elastic belt, 40 min/time, once a day, three times a week. The curative effect was evaluated after 12 weeks, which included fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), nerve conduction velocity and static balance function of eye-opened and eye-closed condition in Pro-Kin 254 balance assessment equipment.Results:Before exercise intervention, there were no significant differences in any measurements among the three groups (all P>0.05). After exercise intervention, the FBG, HbA1c, motor nerve conduction velocity of common peroneal nerve, sensory nerve conduction velocity of common peroneal nerve, sway length and area in the eye closed test of Pro-Kin254 balance assessment in the aerobic exercise group were significantly better than those in the control group[(6.26±0.28) vs. (6.76±0.68) mmol/L, (5.75±0.42)% vs. (6.48±0.37)%, (45.36±8.78) vs. (42.16±6.78) m/s, (38.75±8.14) vs. (35.45±8.34) m/s, (513±39) vs. (613±71) mm, (678±58) vs. (1 024±98) mm 2] (all P<0.05); the above indexes of the combined training group [(6.03±0.36) mmol/L, (5.27±0.35)%, (49.51±9.76) m/s, (42.87±7.18) m/s, (425±38) mm, (535±47) mm 2] were significantly better than those in the other two groups, the sway length and area in the eye open test of Pro-Kin254 balance assessment were also significantly superior to those in the other two groups [(316±21) vs. (395±18), (436±28) mm and (689±33) vs. (782±30), (824±70) mm 2] (all P<0.05). Conclusion:Aerobic exercise combined with resistance exercise can better improve the levels of blood glucose and HbA1c, increase nerve conduction rate and improve static balance ability compared with simple aerobic exercise in patients with DPN.

ABSTRACT

To investigate the protective effect of the seed oil of Abelmoschus esculentus on gastric ulcer,two acute gastric ulcer mice models were established by intragastric administration of aspirin or absolute ethanol,respectively.Clinical index of ulcer area,ulcer index,gastric volume,gastric pH value,free acidity,total acidity,and histopathological assessment were measured to evaluate the injuries of gastric ulcer and the protective effect of okra seed oil In order to comprehensively uncover the possible underlying mechanism,a series of biochemical assays were also performed,including serum TNF-α,IL-6,IL-10 and Tbil,NO,MPO and SOD in the stomach included.Moreover,the ALT,AST and ALP in the liver of mice were also tested to evaluate the possible hepatic toxicity of the seed oil.The results indicated that the seed oil of A.esculentus exerted protective effect in ethanol-induced gastric ulcer mice by reducing the ulcer area and ulcer index,declining the free and total acidity,and increasing the pH value of gastric content.Histopathological observation showed the gastric mucosa of the acute gastric ulcer mice induced by alcohol was incomplete and severely damaged,with submucosal edema and nuclear pyknosis,as well as glandular structure disappearing,compared with that of normal mice.What's more,a number of inflammatory cell infiltration occured in the gastric mucosa of alcohol-model mice,with messes of neutrophils,lymphocytes,eosinophils and plasma cells.Okra seed oil could improve the damaged structure of the gastric mucosa and gland caused by ethanol,but could not ameliorate the condensation of nucleus and infiltration of inflammatory cells.Biochemical analysis revealed that the seed oil of A.esculentus could counteract the damage induced by ethanol via decreasing Tbil and TNF-α in serum,decreasing NO and myeloperoxidase,and increasing SOD in stomach.Meanwhile,okra seed oil exhibited protective effect in aspirin-induced gastric ulcer mice by increasing the gastric content pH,and reducing free and total acidity.Compared with the control group,the gastric mucosa of aspirin-model group showed multifocal coagulation necrosis,sheet edema and infiltration of inflammatory cells by histopathological assessment.Compared with the aspirin-model group,the soybean oil group and okra seed oil group could ameliorate the inflammatory cell infiltration.Biochemical analysis revealed that okra seed oil could counteract the injury induced by aspirin via decreasing TNF-α and IL-6,and increasing IL-1O in serum,decreasing NO and MPO and increasing SOD in stomach.In a word,the okra seed oil exerted protective effect on acute gastric ulcer by anti-inflammation,anti-oxidation and hepatocyte protection.The okra seed oil deserves further development and utilization.

ABSTRACT

BACKGROUND:Evaluation of vertical jumping ability is usual y only limited to height measurements. The measurements of parameters that describe kinetic factors may provide a better assessment of a patient’s jumping ability. OBJECTIVE:To determine the deficit in one-legged vertical jumping ability and to clarify the relationships between the maximum jumping height and the maximum power, force and velocity during one-legged vertical jumps after anterior cruciate ligament reconstruction. METHODS:Twenty-five healthy subjects (10 males and 15 females) and 25 anterior cruciate ligament reconstructed patients (10 males and 15 females) participated in this study. The isokinetic quadriceps femoris strength and one-legged vertical jumping ability were evaluated by the height, power, force and velocity in al subjects. RESULTS AND CONCLUSION:(1) The maximum height of the one-legged vertical jumps was only significantly correlated with the maximum force in the healthy subjects (P<0.05). (2) However, for the reconstructed and unreconstructed legs in anterior cruciate ligament reconstructed patients, the maximum jumping height was significantly correlated with the maximum power, force and velocity during one-legged vertical jumps (P<0.05). (3) These findings suggest the importance of a knee strategy during one-legged vertical jumps for rehabilitation after anterior cruciate ligament reconstruction. Assessment of the jumping ability after anterior cruciate ligament reconstruction may be determined by the maximum power instead of the maximum jumping height.

ABSTRACT

In order to evaluate the effect and mechanism of the mulberry leaf alkaloid, flavones, and polysaccharide intervention on diabetes, the overall metabolite profiling characteristics for the plasma of diabetic mouse was performed by using an ultra-performance liquid chromatography/electrospray-tandem mass spectrometry (UPLC-ESI-MS). The 8 potential biomarkers were found in diabetic mice plasma based on the data of MS/MS characteristics obtained from the UPLC-OrbitrapMS analysis, which mainly involved in sphingolipids, amino acid metabolic pathway. The principal component analysis showed that the normal group and model group were obviously distinguished and implied that metabolic disturbance was happened in diabetic mice plasma. The extracts of mulberry leaf flavonoids, polysaccharide, alkaloid had exhibited the effects of callback function for diabetic mice through regulating the amino acid metabolism and sphingolipid metabolism.
