ObjectiveTo investigate treatment of severe acute pancreatitis (SAP) concurrent peripancreatic walled-off necrosis.MethodsThe clinical data and treatment of a patient with SAP from the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The results of discussion of multidisciplinary team (MDT) were summarized.ResultsThe patient was admitted for the SAP with high fever, abdominal pain, and dyspnea for 2 weeks. The enhanced CT scan of the upper abdomen presented severe acute necrotizing pancreatitis with massive peripancreatic walled-off necrosis and pleural effusion. After the full discussion of SAP MDT, the percutaneous sinus tract necrosectomy (PSTN) was performed to relieved the symptom. After the two-stage PSTN treatment, the peripancreatic necrotic tissue was obviously reduced, the drainage was unobstructed, the clinical symptoms and biochemical indicators were obviously improved, and the patient was discharged on day 6 after the surgery.ConclusionsSAP is a critical situation with rapid progression and high mortality, and timing and approach of intervention for complications are very difficult to handle. PSTN could treat SAP with early appearance of infection or walled-off necrosis, which has advantages of less trauma, higher efficiency, and faster recovery as compared with traditional method and is of valuable in clinical practice.
Objective To investigate the load distribution on the more painful and less painful limbs in patients with mild-to-moderate and severe bilateral knee osteoarthritis (KOA) and explore the compensatory mechanisms in both limbs among bilateral KOA patients with different severity levels. Methods A total of 113 participants were enrolled between July 2022 and September 2023. This cohort comprised 43 patients with mild-to-moderate bilateral KOA (Kellgren-Lawrence grade 2-3), 43 patients with severe bilateral KOA (Kellgren-Lawrence grade 4), and 27 healthy volunteers (healthy control group). The visual analogue scale (VAS) score for pain, the Hospital for Special Surgery (HSS) score, passive knee range of motion (ROM), and hip-knee-ankle angle (HKA) were used to assess walking pain intensity, joint function, and lower limb alignment in KOA patients, respectively. Motion trajectories of reflective markers and ground reaction force data during walking were captured using a gait analysis system. Musculoskeletal modeling was then employed to calculate biomechanical parameters, including the peak knee adduction moment (KAM), KAM impulse, peak joint contact force (JCF), and peak medial/lateral contact forces (MCF/LCF). Statistical analyses were performed to compare differences in clinical and gait parameters between bilateral limbs. Additionally, one-dimensional statistical parametric mapping was utilized to analyze temporal gait data. Results Mild-to-moderate KOA patients showed the significantly higher HSS score (67.7±7.9) than severe KOA patients (51.9±8.9; t=8.747, P<0.001). The more painful limb in all KOA patients exhibited significantly greater HKA and higher VAS scores compared to the less painful limb (P<0.05). While bilateral knee ROM did not differ significantly in mild-to-moderate KOA patients (P>0.05), the severe KOA patients had significantly reduced ROM in the more painful limb versus the less painful limb (P<0.05). Healthy controls showed no significant bilateral difference in any biomechanical parameters (P>0.05). All KOA patients demonstrated longer stance time on the less painful limb (P<0.05). Critically, severe KOA patients exhibited significantly higher peak KAM, KAM impulse, and peak MCF in the more painful limb (P<0.05), while mild-to-moderate KOA patients showed the opposite pattern with lower peak KAM and KAM impulse in the more painful limb (P<0.05) and a similar trend for peak MCF. Conclusion Patients with mild-to-moderate KOA effectively reduce load on the more painful limb through compensatory mechanisms in the less painful limb. Conversely, severe bilateral varus deformities in advanced KOA patients nullify compensatory capacity in the less painful limb, paradoxically increasing load on the more painful limb. This dichotomy necessitates personalized management strategies tailored to disease severity.

Methods The clinical data of 11 patients with recurrent non-Hodgkin′s lymphoma after auto-HSCT from January 2000 to December 2010 were collected, including nine males and 2 females with the median age of 39 years (13-48 years old), and the median duration of the disease was 3 years (27 months-6.5 years). All patients were relapsed or refractory cases. After auto-HSCT, complete remission was found in 8 and partial remission was in 3. The recurrence median time after auto-HSCT was 15 months. The patients underwent allo-HSCT after the recurrence of the disease. In the 11 patients, human leukocyte antigen (HLA) full matched (6/6) in 6, 5/6 matched in 3, and 4/6 matched in 2; the same gender in 6 and different gender in 5. FBC conditioning regimen: fludarabine 30 mg/m2 for 1-5 days, BU 12-14 mg/kg in 4 days of oral, CY 120 mg/kg in 2 days. Grafts are peripheral blood stem cells plus bone marrow. Prevention of graft-versus-host disease (GVHD): HLA full-matched by CsA+short-term MTX+MMF and mismatched by ATG+CsA+short-term MTX+MMF. Results All of the 11 patients received hematopoietic reconstruction, acute GVHD occurred in 6 cases (54.55%), including degree Ⅰ plus Ⅱ in 4, degree Ⅲ in 1 and degree Ⅳ in 1. One patient died of infection due to degree Ⅳ GVHD, and the rest had been effectively controlled. Chronic GVHD occurred in 7 patients (63.64%); limited type was in 4 in and extensive type was in 3. During the follow-up period of 8 months-9 years, 4 patients relapsed 8, 15, 21, and 34 months after transplantation, and the other 6 patients was still alive. Conclusion Allo-HSCT is effective on relapsing non-Hodgkin′s lymphoma after auto-HSCT.
