Objective:To investigate the expression and clinical significance of Prohibitin 2(PHB2)in the kidney tissue of patients with Diabetic Kidney Disease(DKD).Methods:From March 2015 to May 2024,samples were collected from 16 patients diagnosed with diabetic nephropathy through renal biopsy,who met the inclusion criteria(referred to as the DKD group).Additionally,20 patients with renal tumors undergoing nephrectomy,who had partially normal kidney tissue,were selected to serve as the control group(NC group).The pathological changes of the two groups of samples were evaluated by HE and PAS staining.Immunohistochemistry was utilized to analyze the differences in PHB2 protein expression between the two groups.Pearson or Spearman correlation methods were applied for statistical analysis.Results:PHB2 was expressed in renal tubules,and its expression level in the diabetic kidney disease(DKD)group was significantly lower than that in the normal control(NC)group(P＜0.05).Additionally,the expression level of PHB2 in diabetic nephropathy was found to be negatively correlated with glycated hemoglobin,serum creatinine,cystatin C,and blood urea nitrogen(P＜0.05).In contrast,there was a positive correlation between PHB2 expression and the estimated glomerular filtration rate(eGFR)(P＜0.05).Therefore,PHB2 expression serves as a negative correlation factor for serum creatinine,cystatin C,and blood urea nitrogen,while being a positive correlation factor for eGFR.Conclusions:In patients with diabetic nephropathy,the expression of PHB2 in renal tissue significantly decreases.This reduction in PHB2 levels closely correlates with glucose metabolism and renal function.Low levels of PHB2 may worsen glucose metabolism disorders,renal function damage,and proteinuria.Therefore,PHB2 serves as a potential biomarker for assessing prognosis and offers new insights into the treatment of diabetic kidney disease.

PURPOSE: To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS: A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS: There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

OBJECTIVE: To explore the efficacy of a novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint. METHODS: Retrospective analysis of 13 cases of proximal clavicle fracture with dislocation of sternoclavicular joint treated with sternoclavicular hook-plate from June 2011 to January 2019 in our department. There were 9 males and 4 females, aged 26 to 78 years old, with an average age of (54.08±13.91) years old. All the patients had closed injuries without damage of blood vessels and nerves. The patient's operation time, intraoperative blood loss, hospital stay time, and postoperative complications were recorded. Fracture healing and reduction were evaluated according to X-ray and CT after operation. Constant-Murley score and Rockwood sternoclavicular joint score were used to evaluate limb function at 12 months after operation. RESULTS: All the patients were treated with sternoclavicular hook-plate. The operation time ranged from 50 to 76 min, with a mean of (54.08±13.91) min. The intraoperative blood loss ranged from 20 to 56 ml, with a mean of (46.08±11.15) ml. The hospital stay time ranged from 6 to 14 d, with a mean of (8.31±2.32) d. X-ray and CT examination on the second day after operation showed that all fractures and dislocations were anatomically reduced, and shoulder joint function exercise was performed early. All patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (16.77±4.63) months. The healing time ranged from 9 to 13 d, with a mean of (11.00±1.75) d;and the bone healing time ranged from 3 to 4 months, with a mean of (3.65±0.46) months. There were no complications such as infection, internal fixation failure and nerve injury. At 12 months follow-up, the constant Murley score ranged from 78 to 100, with a mean of 87.83± 11.26; and Rockwood score ranged from 9 to 15, with a mean of 13.70±1.85. Among them, 11 cases were excellent, 1 case was good, and 1 case was general. CONCLUSION The use of the novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint is an effectively internal fixation with high safety, allowing early functional exercise for patients.

OBJECTIVETo explore the impact of IFN-γ + 874 polymorphisms on the outcome in HLA matched sibling HSCT.

METHODSWe used PCR-sequence-specific primer analysis (PCR-SSP) to analyze the polymorphisms of IFN-γ + 874 T/A in 80 recipient and donor pairs from October 2005 to March 2008.

RESULTSRecipients having donors who possessed IFN-γ + 874 A/A genotype had significantly earlier neutrophil recovery compared with those having donors with non-A/A genotype (15 (11 - 27) days vs 18 (12 - 30) days, P = 0.029). And IFN-γ + 874 A/A in both recipients and donors further facilitated neutrophil recovery compared with others (13 (11 - 25) days and 19 (12 - 31) days, P = 0.019). Besides, IFN-γ + 874 A/A in recipients increased the probability of grade II-IV acute graft versus disease (aGVHD) and cytomegalovirus viraemia compared with IFN-γ + 874 T/A or T/T genotype (20% vs 4% P = 0.041, 43.6% vs 16.0% P = 0.032), which lead to increased 5-year transplant-related mortality (TRM) (33.7% ± 6.8% vs 12.0% ± 6.5%, P = 0.050) and decreased 5-year event free survival (EFS) \[(58.2 ± 6.7)% vs (84.0 ± 7.3)%, P = 0.032\] compared with the latter. IFN-γ + 874 A/A in both recipients and donors also significantly increased the probability of grade II-IV aGVHD and cytomegalovirus viraemia compared with the other (21.7% vs 5.9%, P = 0.050; 45.7% vs 20.6%, P = 0.020), which caused increased 5-year TRM \[(31.6 ± 7.5)% vs (13.6 ± 6.5)%, P = 0.048\] and decreased 5-year EFS \[(56.8 ± 7.3)% vs (79.4 ± 6.9)%, P = 0.037\] compared with the other.

CONCLUSIONIn HLA-matched sibling HSCT setting, the presence of IFN-γ + 874 T allele in recipients or in both recipients and donors significantly decreased the risk of grade II-IV aGVHD and CMV infection and increased EFS. While IFN-γ + 874 A/A in donors or in both recipients and donors was associated with shorter duration to neutrophil recovery.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.

METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.

RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).

CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.
