Donor-derived cell-free DNA (dd-cfDNA) based liquid kidney biopsies have the potential to detect the chances of kidney transplant rejection. Several studies have found that dd-cfDNA can be used to determine the risk of kidney transplant rejection and may correlate with antibody-mediated rejection (ABMR), T cell-mediated rejection (TCMR), and estimated glomerular filtration rate (eGFR). A high concentration of dd-cfDNA in the body fluids may indicate possible transplant rejection since dd-cfDNA is released as a result of apoptotic and necrotic processes initiated by the recipient’s immune system. dd-cfDNA assays have advantages over conventional biopsies since they are noninvasive, and therefore, have the potential to provide a safe and reliable biomarker. Different dd-cfDNA levels have been reported above a number of cutoff thresholds: ABMR at 2.45% and TCMR at 1.3%, compared with 0.44% in healthy patients; and eGFR at 2.5%, a decrease of 25% compared with healthy patients. These results indicate the levels of dd-cfDNA that may be used to signal possible kidney rejection. dd-cfDNA assay is a rapid technique, making it particularly useful in emergencies, and further research into its use in the study of kidney rejection should prove beneficial.

Objective:To compare the mid-to long-term clinical outcomes between suture anchor and simple suture for acute injury to lateral ankle ligament (cauda equina tear near the insertion).Methods:This retrospective study included 146 patients (professional and semi-professional athletes) who had been treated for acute injury to lateral ankle ligament (cauda equina tear near the insertion) at Department of Sports Medicine, The Third Hospital Affiliated to Peking University from June 2007 to May 2017.They were 101 males and 45 females, with an age of (27.1±10.3) years (from 12 to 62 years). Depending on ligament repair techniques, the patients were divided into a suture anchor group of 81 cases subjected to reconstruction of the torn ligament with a 1.8 mm suture anchor, and a simple suture group of 65 cases subjected to direct suture of the torn ligament with a braided thread. The 2 groups were compared in terms of visual analog scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and Tegner scores at preoperation and the last follow-up, time and level of postoperative motion recovery, proportion of limited joint motion, incidence of re-sprain and patient satisfaction.Results:There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P>0.05). The mean follow-up duration was (46.1±14.1) months (from 36 to 132 months). The VAS pain score, AOFAS ankle-hindfoot score and Tegner score at the last follow-up were significantly improved than those before operation in all the patients ( P<0.05). Postoperatively, there was no significant difference between the 2 groups in VAS pain score, AOFAS ankle-hindfoot score, Tegner score, incidence of re-sprain or proportion of limited joint motion ( P> 0.05). The suture anchor group was significantly better than the simple suture group in the level of postoperative motion recovery (92%±13% versus 89%±13%) and time of postoperative motion recovery [(4.2±1.1) months versus (4.6±1.0) months] ( P<0.05). Conclusions:Ligament repair, either by suture anchor or by simple suture, is a reliable procedure for patients with high sports demands after severe acute injury to the lateral ankle ligament. Compared with simple suture, suture anchor may accelerate postoperative motion recovery to the pre-injury level.

Background: Granular cell tumor (GCT) is an uncommon tumor, and gastrointestinal tract GCT is even more rare. Aims: To investigate the clinicopathological characteristics, treatment and prognosis of gastrointestinal tract GCT. Methods: Nine cases of gastrointestinal tract GCT from January 2017 to June 2021 at the 903rd Hospital of Joint Logistics Support Force, PLA and Jinhua Municipal Central Hospital Medical Group were retrieved. The clinical data, histopathological characteristics, treatment, and prognosis were retrospectively analyzed. Results: In the 9 patients with gastrointestinal tract GCT, ratio of male to female was 2:1, age at diagnosis was 19-60 years, with a median age of 52 years. Six GCT were found in esophagus, 2 in colorectum and 1 in anus. Endoscopic results showed submucosal protrusion or sessile polyps ranging in size from 2-12 mm with a median of 5 mm. Histology results showed that tumors were located in mucosa and/or submucosa, arranged in solid sheets or nests, with an infiltrative margin and inflammatory infiltrates. Tumor cells were mainly plump and polygonal with abundant cytoplasm and eosinophilic granules. Nuclei were small, the nuclear-cytoplasmic ratio was very low. Mitotic figure was rare. Immunohistochemistry results showed that S100 and CD68 proteins were positive in all patients, SOX10, CD56, Calretinin and Syn were positive in some patients, and CKp, Desmin, SMA, CD117, CD34, Dog1, and α-inhibin were negative in all patients. Esophageal and colorectal GCT patients received endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD). The anal GCT patient underwent local resection. Recurrence or metastasis were not observed during 9-53 months of follow-up. Conclusions: Gastrointestinal tract GCT is rare with non-specific clinical symptoms and submucosal protrusion or sessile polyps under endoscopy. Gastrointestinal tract GCT has special pathomorphology and immunophenotype. EMR or ESD is recommended for small and superficial lesions. Long-term follow-up should be performed.

Objective: To investigate clinical outcomes of modified reattachment of superior peroneal retinaculum (SPR) for patients with recurrent peroneal tendon dislocation. Methods: A total of 24 cases with recurrent peroneal tendon dislocation from December 2012 to June 2017 were treated with modified reattachment of SPR. There were 20 males and 4 females. The average age was 24.9±9.3 years (14-48 years). The average BMI was 23.18±3.50 kg/m² (15.8-32.2 kg/m²). A 4-5 cm incision was made along the lateral margin of the fibula and curved distally around the fibular tip in line with the peroneal excursion. The superior peroneal retinaculum, peroneus longus and peroneus brevis were exposed. The periosteum and SPR were stripped from the fibula. The false pouch was formed. Two suture anchors were inserted into the postero-lateral ridge of the lateral malleolus without damaging the cartilaginous ridge, after which the SPR was reattached to the lateral malleolus with the anchored suture. The inner layer of the false pouch was incised, while the outer layer (periosteum) was sutured with the SPR in a pants-over-vest style. The following items, including American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), rate of return to previous sports level, time to return to sports activity, complication, and patients satisfaction were evaluated preoperatively and at the final follow-up. Results: The average operation duration was 36.1±8.8 min (20-51 min). The blood loss was 1-10 ml, average 4.1±2.7 ml. The follow-up was carried out in 22 cases for mean 33.9±15.7 months (13-61 months). AOFAS score was improved from 77.8±7.8 points to 95.5±4.3 points significantly (t=-11.89, P<0.001). VAS score was reduced from 4.2±2.4 to 0.3±0.8 significantly (t=7.69, P<0.001). Mean duration return to sports activity was 5.0±1.9 months (3-10 months). A total of 20 patients (91%) returned to their previous sports level. Only one patient (5%) was found with limitation of range of motion, while two patients (9%) reported pain at the scar site without recurrence. The satisfaction rate was 91%. Conclusion Clinical outcomes of modified reattachment of SPR for patients with recurrent peroneal tendon dislocation was safe and effective.
