Objective:To explore the clinical value of a trinity strategy for the treatment of multiple orthopedic trauma.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 267 patients with multiple orthopedic trauma admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the First Affiliated Hospital of Navy Medical University from June 2013 to May 2023, including 862 males and 405 females, aged 18-93 years [(55.2±19.8)years]. Associated injuries included hemorrhagic shock in 632 patients, traumatic wet lung in 274, cranial injuries in 135, abdominal and pelvic bleeding in 116, pneumothorax in 89, urinary injury in 13, and vesical rupture in 8. All the patients were treated with the trinity strategy and the treatment process was divided into the phases of first aid, remodeling, and rehabilitation. The first aid phase focused on stabilizing symptoms and saving lives; the remodeling phase centered on restoring the anatomical structure and alignment; the rehabilitation phase aimed for functional recovery through the integration of both Western and traditional Chinese medicine. The all-cause mortality within 30 days after surgery and fracture healing time were calculated; the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, Hospital for Special Surgery (HSS) knee score and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at the last follow-up and the overall excellent and good rate of all joint function scores were measured. The short form health survey (SF-36) scores were collected preoperatively and at 6 months postoperatively, including 8 aspects such as physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The incidence of postoperative complications was recorded.Results:All the patients were followed up for 6-18 months [(10.2±4.2)months]. The mortality rate during the acute phase (within 30 days after surgery) was 2.37% with 12 deaths due to hemorrhagic shock, 10 due to traumatic brain injury, 6 due to multiple organ dysfunction syndrome (MODS), and 2 due to pulmonary infection. The average fracture healing time averaged 3.8-18 months [(11.5±4.2)months], with 89.49% of the patients having bone union within 12 months after surgery, 8.93% having bone union within 18 months after surgery, and 1.58% undergoing reoperation. For the patients with internal fixation failure and nonunion, the average healing time was extended to (10.2±2.2)months and (13.7±3.3)months respectively. At the last follow-up, the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, HSS knee score, and AOFAS ankle-hindfoot score were 83.93%, 90.24%, 94.12%, 85.57%, 88.46%, and 92.31% respectively, with an overall excellent and good rate of 89.11%. At 6 months after surgery, the SF-36 scores of all the patients in the eight dimensions,including the physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health were (74.4±8.6)points, (44.7±14.4)points, (77.4±10.9)points, (68.4±18.2)points, (72.5±16.0)points, (76.8±8.7)points, (49.9±17.6)points, and (72.8±17.9)points, significantly improved compared with those before operation [(63.4±12.7)points, (30.9±17.4)points, (56.4±18.0)points, (55.4±24.7)points, (53.5±21.0)points, (55.8±24.3)points, (36.9±24.0)points, (58.8±21.6)points] ( P<0.01). Complications of different degrees occurred in 214 patients (16.89%), including lung infections in 118 patients (9.31%), lower extremity deep vein thrombosis in 50(3.95%), pressure injuries in 26(2.05%), internal fixation failure in 12(0.95%), and nonunion in 8(0.63%). Conclusions:The trinity strategy provides whole-process management, personalized treatment, and overall rehabilitation for multiple orthopedic trauma. It can decrease mortality, shorten fracture healing time, improve joint function and quality of life, and reduce the incidence of complications.

【Objective】 To explore the feasibility and efficacy of laparoscopic bladder muscle flap ureteroplasty in the treatment of long-segment injury in the middle and lower ureter and to summarize the clinical experience. 【Methods】 The clinical data of 6 patients treated in our hospital during Oct.2018 and Aug.2021 were retrospectively analyzed. Four of them had long-segment ureteral mucosal cuff-like avulsion during ureteroscopic lithotripsy and could not undergo end-to-end ureteral anastomosis or reimplantation, and then laparoscopic bladder muscle flap ureteroplasty plus lumbaris major fixation of the bladder was performed immediately. The other 2 patients had to undergo this procedure due to stricture. 【Results】 All operations were successful. The median ureteral avulsion or ureteral stricture length was 14.5(6, 16) cm, muscle flap length 16.5(8,18) cm, operation time 190 (160, 240) min, blood loss 175 (100, 250) mL, postoperative hospital stay 8 (7, 12) days, and postoperative creatinine (89.38±21.74) μmoI/L. No major complications occurred. One patient developed urinary leakage, which returned to normal after active glycemic control and nutritional therapy; one patient developed postoperative absorption fever, which recovered after physical cooling. During the follow-up of 6 to 45 months, CT showed mild hydronephrosis in some patients, but no ureteral stenosis, impaired renal function or other complications, and patients complained no subjective discomfort. 【Conclusion】 Laparoscopic bladder muscle flap ureteroplasty is safe and effective for patients with long-segment injury in the middle and lower ureter. It has the advantages of small trauma, few long-term complications, and rapid recovery and improvement of renal function. If necessary, it can be combined with lumbaris major fixation of the bladder to shorten the distance from the muscle flap to the broken end of the ureter and to reduce the tension of the anastomosis.

【Objective】 To compare the efficacy, safety and survival of partial nephrectomy (PN) and radical nephrectomy (RN) in the treatment of clinical T1b and T2a renal cell carcinoma (RCC). 【Methods】 A total of 115 patients with stage T1b and T2a RCC treated during Apr.2014 and Jul.2017 were retrospectively analyzed. According to the different surgical methods, the patients were divided into PN group (n=55) and RN group (n=60). The clinical data and prognosis of the two groups were compared. 【Results】 There were no significant differences in the general clinical data and perioperative related factors between the two groups (P>0.05). The incidence of complications was significantly higher in PN group than in RN group (P=0.024), but there was no significant difference in serious complications (Clavien grade ≥3) (P>0.05). In terms of renal function recovery, there was no significant difference in serum creatinine between the two groups before operation (P>0.05), but the serum creatinine was significantly lower in PN group than in RN group on the 1st day, 3rd, 6th and 12th months after operation (P<0.05). After more than 5 years of follow-up, there was no significant difference in 5-year survival rate, overall survival rate, recurrence and metastasis rate, and cancer specific survival rate between the two groups (P>0.05). 【Conclusion】 Both PN and RN are safe and effective in the treatment of stage T1b and T2a RCC, and can achieve good oncological control effects. Compared with RN, PN can fully and effectively protect the postoperative renal function, but it causes more surgical complications. However, there is no significant difference in severe complications (Clavien grade ≥3).

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To compare the clinical effect of "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children.Methods:A retrospective cohort analysis was made on 106 children with Gartland type III posterolaterally-displaced supracondylar humerus fracture treated in Anhui Provincial Children′s Hospital from March 2020 to June 2022, including 58 males and 48 females; aged 1-12 years [(8.7±2.3)years]. The patients were assigned to "de-sharpening" intramedullary elastic reduction with Kirschner wire (study group, n=50) and traditional three-dimensional manipulation (control group, n=56). The operation time, frequency of intraoperative fluoroscopy, fracture healing time, difference of Baumann angle between the normal and injured side at postoperative 3 and 6 months, elbow function Flynn score at last follow-up and complications were compared between the two groups. Results:All children were followed up for 6-12 months [(8.5±1.2)months]. The operation time and frequency of intraoperative fluoroscopy were (32.9±3.7)minutes and (20.6±5.4)times in study group, significantly different from (45.6±10.1)minutes and (32.5±8.2)times in control group (all P<0.05). The fracture healing time was (33.0±5.1)days in study group, similar with (33.8±4.7)days in control group ( P>0.05). At 3 and 6 months after operation, the difference of Baumann angle between the normal and injured side was (3.2±0.8)°and (2.3±0.6)°in study group compared to (6.0±2.1)°and (5.8±1.3)°in control group (all P<0.01). According to the elbow function Flynn score at the last follow-up, the results were excellent in 44 children, good in 5 and fair in 1, with the excellent and good rate of 98.0% (49/50) in study group, and were excellent in 47 children, good in 5 and fair in 4, with the excellent and good rate of 92.9% (52/56) in control group ( P>0.05). There were no following complications in both groups, such as osteomyelitis, poor fracture healing, compartment syndrome, iatrogenic neurovascular injury or myositis ossificans. Conclusions:Both "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children can achieve elbow joint function recovery, with low incidence of complications. However, the former avoids repeated manual reduction, with shorter operation time, less frequency of intraoperative fluoroscopy and better correction of the coronal plane deformity and rotation deformity.

Methods:Two thousand standard sections images werre collected from 2 000 clinical retrospective pediatric hip ultrasound videos from January 2019 to January 2021. All standard sections were annotated by the annotation team through the self-designed software based on Python 3.6 environment for image cross-media data annotation and manual review standardization process with unified standards. Among them, 1 753 were randomly selected for training the deep learning system, and the remaining 247 were used for testing the system. Further, 200 standard sections were randomly selected from the test set, and 8 clinicians independently completed the film reading annotation. The 8 independent results were then compared with the AI results.Results:The testing set consists of 247 patients. Compared with the clinician's measurements, the area under the receiver operating characteristic curve (AUC) of diagnosing hip joint maturity was 0.865, the sensitivity was 76.19%, and the specificity was 96.9%. The AUC of AI system interpretation under Graf detailed typing was 0.575, the sensitivity was 25.90%, the specificity was 89.10%. The 95% LoA of α-angle determined by Bland-Altman method, of -4.7051° to 6.5948° ( Bias -0.94, P<0.001), compared with clinicians' measurements. The 95% LoA of β-angle, of -7.7191 to 6.8777 ( Bias -0.42, P=0.077). Compared with those from 8 clinicians, the results of AI system interpretation were more stable, and the β-angle effect was more prominent. Conclusion:The AI system can quickly and accurately measure the Graf correlation index of standard DDH ultrasonic standard diagnosis plane.

Objective To assess the efficacy and safety of post operative adjuvant concurrent chemoradiotherapy for patients with high-risk salivary gland tumors (SGT).Methods Fifty-two patients with moderate or high malignant pathological stage complicated with locally advanced stage Ⅲ/ⅣA±positive margin/close margin admitted to Shanghai Ninth People's Hospital from 2016 to 2018 were enrolled in this study.Among them,35 patients were male and 17 female with a median age of 55.5 years old (range:21-73 years old).All 52 patients were treated with intensity-modulated radiotherapy and concurrent chemotherapy.Patients with adeno carcinoma of the salivary gland receives concurrent chemotherapy with TP regimen.Patients with lympho epithelial cancer and squamous cell carcinoma were treated with cisplatin regimen.Results Forty-seven patients (90％) completed two cycles of concurrent chemotherapy,and five patients (10％) completed one cycle of concurrent chemotherapy.The median follow-up time was 15.7 months (3.2-34.8 months).The 2-year disease-free survival (DFS) and overall survival (OS) rates were 74％ and 98％.Three patients experienced regional lymph recurrence and 6 cases had distant metastasis.Grade Ⅲ oral mucositis was observed in 30 patients.Grade Ⅲ dermatitis occurred in 5 cases.Only one patient experienced Grade Ⅳ neutropenia,and 2 patients developed Grade Ⅲ neutropenia.DFS was positively correlated with the cycle of postoperative adjuvant concurrent chemotherapy (P=0.006).Conclusions Patients with high-risk SGT can obtain higher 2-year DFS and OS rates and tolerable adverse events after postoperative concurrent chemoradiotherapy.Nevertheless,the long-term outcomes remain to be validated by randomized controlled clinical trials.

OBJECTIVE: To investigate the effects of serum from the obesity patients and obesity patients with Diabetic mellitus on toll-like receptor 4/Nuclear factor -κB p65 (TLR/NF-κB) pathway in human THP-1 monocytes and to explore the inflammatory immune response in obesity. METHODS: Peripheral serum was isolated from healthy volunteers (the control group), the obesity patients (Ob group) and the obesity patients with diabetic mellitus (the Ob with DM group), respectively, 20 in each group. THP-1 monocytes were incubated with the serum for 48 h. The monocytes and culture supernatant were collected. The phosphorylation level of NF-κB p65 protein in THP-1 monocytes was evaluated by Western blot as well as immunofluorescence assay. The TLR4 mRNA expression was evaluated by RT-PCR. ELISA was used to measure the monocyte chemotactic protein-1 (MCP-1) levels in the culture supernatant. RESULTS: In the presence of serum, the obesity group and the obesity with diabetic mellitus group showed the up-regulated phosphorylation level of NF-κB p65 protein and TLR4 mRNA expression in THP-1 monocytes compared with the healthy control group (both P<0.05), and the MCP-1 levels in the obesity patients were up-regulated significantly compared with the healthy control group [healthy control group (26.4 ± 3.9) pg/mL, Ob group (45.8 ± 10.0) pg/mL, Ob with DM group (58.0 ± 15.3) pg/mL; P<0.05]. These parameters were further up-regulated in the obesity patients with diabetic mellitus patients. CONCLUSION The serum from the obesity patients or the obesity patients with diabetes can induce monocyte dysfunction, which might be related to the activation of TLR4/NF-κB signaling pathway.
