Objective:To explore the surgical treatment strategies for Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures.Methods:A retrospective analysis was performed on the clinical data of 25 adult patients with Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures, admitted to the Upper Extremity Orthopaedics Department of Zhengzhou Orthopaedic Hospital from June 2013 to June 2023. There were 15 males and 10 females, with an average age of 43.5±14.7 years (range: 20-67 years). Among them, 5 cases were complicated with humeroulnar joint dislocation. The patients were divided into two groups: 17 cases were treated with open reduction and internal fixation (ORIF) of radial head fractures combined with ORIF of proximal ulnar fractures (open reduction group), and 8 cases were treated with radial head replacement combined with ORIF of proximal ulnar fractures (radial head replacement group). At the last follow-up, elbow joint range of motion was recorded, and pain, elbow function, and subjective upper limb function were evaluated using the Visual Analogue Scale (VAS), Mayo Elbow Performance Score (MEPS), and Disabilities of the Arm, Shoulder and Hand (DASH) scale. The incidence of complications was also recorded.Results:All 25 patients were followed up for an average of 25.6±9.0 months (range: 12-45 months). At the last follow-up, the affected elbows in the open reduction group had a flexion of 124.47°±12.59° (range, 90°-140°), extension of 21.12°±10.07° (range, 10°-50°), pronation of 48.59°±11.62° (range, 20°-61°), and supination of 48.53°±8.43° (range, 30°-60°). In the radial head replacement group, the affected elbows showed flexion of 128.75°±13.17° (range, 100°-140°), extension of 14.00°±7.71° (range, 0°-25°), pronation of 61.25°±10.26° (range, 60°-80°), and supination of 71.88°±10.33° (range, 60°-80°). The MEPS score in the open reduction group was 82(75, 85) points (range, 55-90 points), the VAS pain score was 1(1, 2) points (range, 0-3 points), and the DASH score was 9(8, 14) points. In the radial head replacement group, the MEPS score was 90(85, 90) points (range, 85-90 points), the VAS pain score was 1(0, 1) points (range, 0-1 points), and the DASH score was 5(5, 6) points. Complications included 5 cases of heterotopic ossification, 1 case of incision infection, 1 case of nonunion, 1 case of ulnar nerve injury combined with traumatic arthritis, and 1 case of proximal radioulnar bone bridge formation.Conclusions:Both radial head replacement and open reduction internal fixation combined with proximal ulnar fracture fixation can effectively treat Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures. There was no significant difference in postoperative flexion and extension, but the radial head replacement group demonstrated better forearm rotation and DASH scores postoperatively.

Objective:To construct and validate a nomogram model for predicting sepsis-associated acute kidney injury (SA-AKI) risk in intensive care unit (ICU) patients.Methods:A retrospective cohort study was conducted. Adult sepsis patients admitted to the department of ICU of the 940th Hospital of Joint Logistic Support Force of PLA from January 2017 to December 2022 were enrolled. Demographic characteristics, clinical data within 24 hours after admission to ICU diagnosis, and clinical outcomes were collected. Patients were divided into training set and validation set according to a 7∶3 ratio. According to the consensus report of the 28th Acute Disease Quality Initiative Working Group (ADQI 28), the data were analyzed with serum creatinine as the parameter and AKI occurrence 7 days after sepsis diagnosis as the outcome. Lasso regression analysis and univariate and multivariate Logistic regression analysis were performed to construct the nomogram prediction model for SA-AKI. The discrimination and accuracy of the model were evaluated by the Hosmer-Lemeshow test, receiver operator characteristic curve (ROC curve), decision curve analysis (DCA), and clinical impact curve (CIC).Results:A total of 247 sepsis patients were enrolled, 184 patients developed SA-AKI (74.49%). The number of AKI patients in the training and validation sets were 130 (75.58%) and 54 (72.00%), respectively. After Lasso regression analysis and univariate and multivariate Logistic regression analysis, four independent predictive factors related to the occurrence of SA-AKI were selected, namely procalcitonin (PCT), prothrombin activity (PTA), platelet distribution width (PDW), and uric acid (UA) were significantly associated with the onset of SA-AKI, the odds ratio ( OR) and 95% confidence interval (95% CI) was 1.03 (1.01-1.05), 0.97 (0.55-0.99), 2.68 (1.21-5.96), 1.01 (1.00-1.01), all P < 0.05, respectively. A nomogram model was constructed using the above four variables. ROC curve analysis showed that the area under the curve (AUC) was 0.869 (95% CI was 0.870-0.930) in the training set and 0.710 (95% CI was 0.588-0.832) in the validation set. The P-values of the Hosmer-Lemeshow test were 0.384 and 0.294, respectively. In the training set, with an optimal cut-off value of 0.760, a sensitivity of 77.5% and specificity of 88.1% were achieved. Both DCA and CIC plots demonstrated the model's good clinical utility. Conclusion:A nomogram model based on clinical indicators of sepsis patients admitted to the ICU within 24 hours could be used to predict the risk of SA-AKI, which would be beneficial for early identification and treatment on SA-AKI.

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis-associated acute kidney injury (SA-AKI) is a common organ dysfunction of sepsis, and its incidence and mortality are increasing, which brings heavy economic burden to patients and society. Early diagnosis and effective intervention can block the occurrence and progression of SA-AKI effectively, improve prognosis, and reduce medical costs. Diagnosis on SA-AKI relies on urine volume and serum creatinine, which has the disadvantages of being easily disturbed and delaying. The identification of biomarkers in blood and urine can facilitate diagnosis and provide targeted therapy to enhance the management of SA-AKI. This article reviews the characteristics of a variety of SA-AKI biomarkers that have been found and validated, including pre-damage biomarkers, damage biomarkers and functional biomarkers, and explore the clinical value of newly discovered biomarkers related to the diagnosis and treatment of SA-AKI, such as blood uncoupling protein 2 (UCP2), Sestrin 2 protein and pannexin 1 (PANX1), to provide reference for the early diagnosis and effective treatment of SA-AKI.

Objective:To investigate the influencing factors for textbook outcome (TO) after hepatectomy for hepatolithiasis.Methods:The retrospective case-control study was conducted. The clinicopathological data of 216 patients with hepatolithiasis who were admitted to The First Affi-liated Hospital of Anhui Medical University from January 2015 to March 2023 were collected. There were 69 males and 147 females, aged 61(range, 22-85)years. Observation indicators: (1) treatment situations; (2) TO after hepatectomy; (3) Influencing factors for TO after hepatectomy. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Logistic regression models were used for univariate and multifactorial analyses. Results:(1) Treatment situations. All the 216 patients underwent hepatectomy, including 45 cases of laparoscopic hepatectomies and 171 cases of open hepatectomies, 161 cases of anatomical hepatectomies and 55 cases of non-anatomical hepatectomies. All the 216 patients underwent intraoperative choledochoscopy exploration and lithotripsy. There were 170 patients with normal Oddi sphincter function and 46 patients with Oddi sphincter dysfunction. All the 216 patients underwent biliary drainage, including 198 cases of external T-tube drainage and 18 cases of internal bile-intestinal drainage. The operation time was (226±75)minutes and volume of intraoperative blood loss was (106±82)mL. There were 29 patients with perioperative blood transfusion and 14 patients with intraoperative severe adverse events. There were 189 patients achieved immediate stone clearance. Of 183 patients with intraoperative bile cultures, 76 cases were positive for bacteria culture. (2) TO after hepatectomy. Of 216 patients, 93 cases had postoperative complications, all of which were successfully discharged after active treatment. One patient had surgery-related death within 90 days after surgery, and the cause of death was liver failure. Five patients were readmitted within 90 days after surgery, and 18 patients had postoperative stone residual. Of 216 patients, 164 cases achieved TO postoperatively and 52 cases did not achieve TO postoperatively. (3) Influencing factors for TO after hepatectomy. Results of multivariate analysis showed that cholangitis, stone distribution, surgical approaches, anatomical hepatectomy, immediate stone removal and postoperative review of choledochoscopy were independent influencing factors for TO after hepatectomy in patients with hepatolithiasis ( P<0.05). Conclusion:Cholangitis, stone distribution, surgical approaches, anatomical hepatectomy, imme-diate stone removal and postoperative review of choledochoscopy are independent influencing factors for TO after hepatectomy in patients with hepatolithiasis.

Objective:To compare proximal humerus internal locking system (PHILOS) and Multiloc intramedullary nail in the treatment of proximal humerus fracture-anterior dislocation.Methods:A retrospective study was performed to analyze the data of 33 patients with proximal humerus fracture-anterior dislocation who had been treated by open reduction and internal fixation from June 2015 to April 2021 at Department of Upper Limbs, Zhengzhou Orthopaedic Hospital. According to methods of internal fixation, the patients were divided into an extramedullary group and an intramedullary group. In the extramedullary group of 18 cases subjected to internal fixation with PHILOS, there were 8 males and 10 females with an age of (53.3 ± 10.6) years, and 1 2-part fracture, 15 3-part fractures and 2 4-part fractures by the Neer classification. In the intramedullary group of 15 cases subjected to internal fixation with Multiloc intramedullary nail, there were 8 males and 7 females with an age of (51.5 ± 11.2) years, and 14 3-part fractures and 1 4-part fracture by the Neer classification. The 2 groups were compared in terms of incision length, operation time, intraoperative blood loss, postoperative complications, and visual analog scale (VAS), range of shoulder motion, and Constant-Murley score at postoperative 12 months.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data ( P>0.05). All patients were followed up for (20.8 ± 4.7) months. The incision length in the intramedullary group [(11.6 ± 1.7) cm] was significantly shorter than that in the extramedullary group [(17.6 ± 2.0) cm], and the intraoperative blood loss in the former [(106.7 ± 34.4) mL] was significantly lower than that in the latter [(151.7 ± 45.7) mL] ( P<0.05). The VAS scores at 1 week and 1 month after surgery [2.0 (2.0, 3.0) and 0.0 (0.0, 1.0) respectively] in the intramedullary group were significantly lower than those in the extramedullary group [3.0 (3.0, 3.3) and 1.0 (0.0, 1.3) respectively] ( P<0.05). The external rotation of the shoulder at the last follow-up in the intramedullary group (65.3° ± 15.5°) was significantly larger than that in the extramedullary group (50.6° ± 13.9°) ( P<0.05). There were no significant differences in operation time, incidence of postoperative complications, VAS score at 12 months after operation, Constant-Murley score or range of shoulder motion at the last follow-up between the 2 groups ( P>0.05). Conclusions:In the treatment of proximal humerus fracture-anterior dislocation, open reduction and internal fixation with both PHILOS and Multiloc intramedullary nail can result in a favorable prognosis when the fracture-dislocation is well reduced and fixated. However, the Multiloc intramedullary nail may lead to better early pain relief, less surgical invasion, and better functional recovery of the external rotation of the shoulder.

Objective:To investigate the clinical efficacy of precise hepatectomy for the treatment of recurrent unilateral hepatolithiasis and prognostic factors.Methods:The retrospec-tive case-control study was conducted. The clinicopathological data of 166 patients with recurrent unilateral hepatolithiasis who were treated by precise hepatectomy in the First Affiliated Hospital of Anhui Medical University from January 2015 to January 2021 were collected. There were 51 males and 115 females, aged (58±12)years. Observation indicators: (1)diagnosis and classification; (2) surgical and intraoperative situations; (3) postoperative situations; (4) follow-up; (5) analysis of prognostic factors. Follow-up was conducted using the outpatient examination and telephone inter-view to detect final stone clearance or recurrence and survival of patients up to August 2021. Patients with T-tube were performed T-tube cholangiography or choledochoscopy to evaluate the final stone clearance rate at postoperative week 8. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages. Univariate and multi-variate analyses were conducted using the Logistic regression model. Results:(1) Diagnosis and classifica-tion: 166 patients were diagnosed as hepatolithiasis by preoperative imaging examination and intraoperative evaluation, including 134 cases with common bile duct stones. Of the 166 patients, 115 cases had stones located in the left lobe of liver and 51 cases had stones located in the right lobe of liver. There were 111 cases with bile pigment stones, 31 cases with cholesterol stones, 24 cases with mixed type of stones. There were 9 cases classified as Tsunoda type Ⅰ, 89 cases as Tsunoda type Ⅱ, 65 cases as Tsunoda type Ⅲ, 3 cases as Tsunoda type Ⅳ. There were 12 cases classified as type Ⅰ, 99 cases as type Ⅱ, 47 cases as type Ⅲ, 8 cases as type Ⅳ according to Japanese classification in 2001. All the 166 patients were classified as type Ⅰ based on Chinese classification. According to the classification of author team, 166 patients were classified as type Ⅱ. (2) Surgical and intra-operative situations: 119 of 166 patients had liver lobe or segment atrophy. All the 166 patients underwent precise hepatectomy combined with different methods of drainage, of which 28 cases underwent left hemihepatectomy, 11 cases underwent right hemihepatectomy, 1 case underwent liver resection of segment Ⅰ, 5 cases underwent liver resection of segment Ⅱ, 5 cases underwent liver resection of segment Ⅲ, 8 cases underwent liver resection of segment Ⅳ (left medial lobe), 3 cases underwent liver resection of segment Ⅴ, 2 cases underwent liver resection of segment Ⅵ, 2 cases underwent liver resection of segment Ⅷ, 68 cases underwent liver resection of segment Ⅱ and Ⅲ (left lateral lobe), 3 cases underwent liver resection of segment Ⅴ and Ⅵ, 6 cases underwent liver resection of segment Ⅴ and Ⅷ (right anterior lobe), 21 cases underwent liver resection of segment Ⅵ and Ⅶ (right posterior lobe), 1 case underwent liver resection of segment Ⅱ, Ⅲ and Ⅳa, 1 case underwent liver resection of segment Ⅴ, Ⅵ and Ⅶ, 1 case underwent liver resection of segment Ⅰ, Ⅱ, Ⅲ and Ⅳ. For biliary drainage methods of 166 patients, 120 patients received T-tube external drainage, 23 cases received choledochojejunostomy, 23 cases received choledochojejunostomy combined with T-tube external drainage. The original cholangiojejunal anastomotic stenosis was found and reconstructed in 10 patients. The operation time was (258±87)minutes and intraopera-tive blood transfusion rate was 16.87%(28/166) of 166 patients. All the 166 patients underwent fiber choledochoscopy, showing 77 cases with normal function of Oddi sphincter, 38 cases with disorder, 40 cases with dysfunction. There were 11 patients undergoing choledochojejunostomy who were not evaluate the function of Oddi sphincter. There were 21.69%(36/166)of patients with intra-hepatic biliary stricture. One hundred and forty-nine of 166 patients were conducted bile culture, showing the positive rate as 75.17%(112/149). There were 22 cases cultured multiple kinds of bacteria. The most common bacterium was Escherichia coli (43 cases), followed by Pseudomonas aeruginosa (12 cases), Klebsiella pneumoniae (9 cases), Klebsiella oxytoca (7 cases), Enterococcus faecium (7 cases). (3) Postoperative situations. The postoperative complication rate of 166 patients was 16.87%(28/166). In the 8 patients with serious complications of Clavien-Dindo grade Ⅲ, 6 cases were performed thoracocentesis or abdominocentesis for effusion, 1 case was stopped bleeding under gastroscopy for stress ulcerbleeding, 1 case was performed surgery for adhesive intestinal obstruction. Two patients with septic shock of Clavien-Dindo grade Ⅳ were converted to intensive care unit for treatment and discharged after recovery. There were 13 patients with biliary leakage, 10 patients with pulmonary infection, 6 cases with incision infection, which were improved after conservative treatments. There was no perioperative death. The instant stone clearance rate of 166 patients was 81.93%(136/166). The duration of postoperative hospital stay of 166 patients was (11±6)days. (4) Follow-up: 166 patients were followed up for (37±17)months. The final stone clearance rate and stone recurrence rate of 166 patients were 94.58%(157/166) and 16.87%(28/166), respectively. According to Terblanche classification of prognosis, there were 91, 36, 25, 14 cases of grade Ⅰ, Ⅱ, Ⅲ, Ⅳ in 166 patients, respectively. Five of the 166 patients underwent intrahepatic secondary malignancy in which 4 cases died. (5) Analysis of prognostic factors: results of univariate analysis showed that biliary culture, the number of previous surgeries, immediate stone clearance, final stone clearance were related factors affecting the prognosis of precise hepatectomy in patients with recurrent unilateral hepatolithiasis ( odds ratio=2.29, 7.48, 2.69, 4.52, 95% confidence interval as 1.09?4.85, 2.80?19.93, 1.16?6.25, 1.15?17.77, P<0.05). Results of multivariate analysis showed that the number of previous surgeries ≥3 was an independent risk factor affecting the prognosis of precise hepatectomy in patients with recurrent unilateral hepato-lithiasis ( odds ratio=6.05, 95% confidence interval as 2.20?16.62, P<0.05). Conclusions:Precise hepatectomy is safe and effective for the treatment of patients with recurrent unilateral hepato-lithiasis. The number of previous surgeries ≥3 is an independent risk factor affecting the prognosis of precise hepatectomy in patients with recurren t unilateral hepatolithiasis.

Objective:To evaluate the clinical efficacy of the axillary approach in the treatment of scapular glenoid fracture.Methods:A retrospective analysis was performed of the 12 patients who had been treated for scapular glenoid fracture from November 2019 to April 2021 at Department of Upper Limb Orthopaedics, Zhengzhou Orthopaedic Hospital. They were 4 males and 8 females, aged from 30 to 75 years (mean, 53.5 years). According to the Ideberg classification, there were 2 cases of type Ⅰa, 9 cases of type Ⅱ and one case of type Ⅴa. All cases were treated through the axillary approach. Two patients complicated with anterior shoulder dislocation were treated with manual reduction under anesthesia before operation and the other 10 cases with special plate fixation through the axillary approach. The 3 patients complicated with fracture of greater tuberosity were fixated with a special plate through the lateral shoulder split deltoid approach. Constant-Murley score, visual analogue scale (VAS) and Hawkins grading were used at the last follow-up to evaluate shoulder function, pain and stability after operation.Results:All patients were followed up for 9 to 20 months (mean, 14.4 months). The operation time ranged from 55 to 110 min (mean, 76.3 min), intraoperative bleeding from 60 to 160 mL (mean, 103.8 mL), and hospital stay from 8 to 14 d (mean, 11.1 d). All incisions healed primarily and all scapular glenoid fractures got united 6 months after operation. The last follow-up showed no shoulder instability, neurovascular injury or internal fixation failure. At the last follow-up, the range of motion of the shoulder was 159.2°±26.1° in forward bending, 156.7°±29.6° in abduction, 48.3°± 15.3° in external rotation (neutral position), and 73.3°±12.3° in internal rotation (neutral position), and the Constant-Murley score was (94.0±5.3) points. The range of motion of the shoulder and Constant-Murley score were significantly improved compared with those before operation (10.8°±11.6°, 7.5°±11.4°, 5.8°±10.0°, 42.5°±16.0° and 4.9±4.0, respectively) (all P<0.05). The VAS score was 0 in 11 patients and 2 in one patient at the last follow-up. Conclusion:The axillary approach is feasible for the treatment of scapular glenoid fracture, because it is hidden and less invasive, leading to good clinical outcomes.

Objective:To investigate the clinical characteristics of adult undifferentiated embryonal sarcoma of the liver (UESL).Methods:A retrospective analysis was performed on the clinical data of 5 patients with UESL who underwent surgical resection and were pathologically confirmed from January 2005 to December 2020 at the First and the Second Affiliated Hospital of Anhui Medical University. All the patients were female aged from 49 to 77 years old. Preoperative CT showed a solid cystic mass with low density and a slight density of cord like septum. Imaging findings were misdiagnosed as hepatocellular carcinoma or cystadenocarcinoma. CA125 was higher in 3 patients,and AFP in all patients was normal.Results:All patients were treated by surgery. The mean diameter of tumor was 20.2 cm (range:15.0 to 30.0 cm). All five patients had vimentin expression in immunohistochemistry. Three cases underwent complete resection of the tumor and achieved R0 resection,2 of them had tumor free survival until the end of the follow-up (89 and 55 months),the other 1 case died from renal cell carcinoma 158 months later. The remaining 2 cases were radically resected,but the tumors were ruptured during operation,and relapsed after 2 months and 19 months respectively. The overall survival was 3 and 26 months respectively.Conclusions:Radical hepatectomy is the first choice for treatment of UESL. Intraoperative tumor rupture should be avoided and implant metastasis is a major factor affecting the prognosis of UESL.
