ABSTRACT

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

ABSTRACT

BACKGROUND@#Bone defect difficult to manage clinically and it is a big challenge to repair it. Secondary metabolites source from herb has shown potential for the treatment of bone defect. @*METHODS@#Mesenchymal stem cells (MSCs) were isolated from mice and incubated with urolithin A (UA) (10, 25, and 50 lg/mL). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was performed to estimate apoptosis and mineralisation was evaluated by alkaline phosphatase assay and alizarin red S staining. A middle femoral defect was induced in mice and bone tissue was prepared for endochondral ossification by treating with UA. The effect of UA was estimated by determining markers of osteoblast proliferation in serum and micro-computed tomography to analyse bone defects. @*RESULTS@#UA enhanced mineralisation of MSCs and osteogenic gene markers in MSCs in vitro. Also, the bone defect score and bone mineral density were improved by UA. Moreover, UA ameliorated the altered Wnt3a protein and histopathological changes in bone defect mice. @*CONCLUSION@#Presented report conclude that UA enhances osteoblast proliferation in bone-defect mice by activating the Wnt pathway.

ABSTRACT

Severe trauma is almost caused by a high energy damage, with a high incidence rate of multiple injuries. Reasonable assessment and resuscitation in hospital at early stage is key to successful care. Trauma resuscitation bay(TRB)is the primary area for early assessment and resuscitation in hospital, which can ensure the rapid rescue to the greatest extent. At present, the early treatment for patients with severe trauma is mainly conducted in the emergency room, which presents many disadvantages that may lead to a decline in the quality of early treatment of trauma. For example, in the limited space, a resucue team is unable to carry out, and bedside radiographic examinations, life-saving operations and rescue for internal emergency patients are affected. With the development of trauma center construction, TRB specifically for early assessment, resuscitation and emergency management of severe trauma comes into being. According to the characters of China's trauma rescue system, the authors illustrate the characteristics, advantages, functions and operational requirements of TRB, the components of TRB at different levels of trauma centers, and the status of TRB construction in China, so as to provide a reference for the construction of TRB at various levels.

ABSTRACT

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

ABSTRACT

Objective:To evaluate the trauma center model in general hospitals for patients with severe trauma.Methods:The data of 1,248 patients with severe trauma (ISS≥16) were retrospectively analyzed who had been admitted to the trauma centers in 6 Chinese general hospitals from January 2019 through June 2020. They were 987 males and 261 females with an age of 50.4 years ± 15.4 years. Their injuries were caused by a traffic accident in 622 cases, falling from a height in 357 cases, a knife in 62 cases, and others (like a heavy object and fall) in 207 cases. Upon admission, their injury severity scores (ISS) were 24.9±8.5 and their Glasgow coma scores (GCS) 12.6±3.6. They were all treated in a scientific and standard manner by a multidisciplinary team at the trauma center of their specific general hospital. Recorded were deaths within 30 days after admission, 30-day mortality and causes of death.Results:All the patients were treated effectively. 101 deaths occurred within 30 days after admission, yielding a 30-day mortality of 8.1%. The main causes of death were severe craniocerebral injury in 56 cases, hemorrhagic shock in 26 cases, multi-organ failure in 11 cases and others in 8 cases.Conclusions:Establishment of trauma centers in China can make up for the disadvantage of over-division of clinical specialties in large general hospitals which has led to insufficient care for patients with severe trauma and multiple injuries. The trauma centers in general hospitals may be a feasible model to be popularized in treatment of patients with severe trauma and multiple injuries.

ABSTRACT

As China has not yet established a sound regional trauma treatment system and standardized trauma centers at all levels, the trauma treatment capability in China is poorer than that in the developed countries. At present, Shaanxi Province has not established a regional trauma treatment system and standardized trauma centers at all levels. Based on the analysis of the characteristics of geography, population and social environment in Shaanxi Province, the authors explore the concept of the trauma treatment system and the construction of trauma centers at all levels in Shaanxi Province on the platform of the trauma center of Shaanxi People's Hospital ( Grade I trauma center) . The authors clarify the respective hardware facilities, team structure, treatment process and quality control goals, training and management system of professional trauma teams in trauma centers at all levels, so as to provide reference for improving the overall level of trauma treatment in Shaanxi Province.
