ABSTRACT

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

ABSTRACT

As food preferences and eating habits form early in life, the development of healthy eating habits in early childhood is a way to prevent diet-related diseases. The dietary pattern approach examines the effect of an overall diet on health outcomes, instead of individual foods or nutrients, thereby presenting a comprehensive evaluation of children's dietary intake. This article reviews the current literature to summarize the main methods for assessing dietary patterns and explore relationships between children's dietary patterns and obesity, puberty onset, cardiovascular diseases, and neurodevelopment. The purpose of this review is to provide evidence-based support for reducing the risk of diet-related diseases in children and recommendations for future research directions.

ABSTRACT

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

ABSTRACT

BACKGROUND@#The past decade has witnessed an ever-increasing momentum of transcatheter aortic valve replacement (TAVR) and a subsequent paradigm shift in the contemporary management of severe aortic stenosis (AS). We conducted a multi-centric TAVR registry based on Chinese patients (the China Aortic valve tRanscatheter Replacement registrY [CARRY]) to delineate the clinical characteristics and outcomes of Chinese patients who underwent TAVR and compare the results between different valve types in different Chinese regions.@*METHODS@#CARRY is an all-comer registry of aortic valve disease patients undergoing TAVR across China and was designed as an observational study that retrospectively included all TAVR patients at each participating site. Seven hospitals in China participated in the CARRY, and 1204 patients from April 2012 to November 2020 were included. Categorical variables were compared using the chi-squared test, and continuous variables were analyzed using a t test or analysis of variance (ANOVA) test. The Kaplan-Meier curve was used to estimate the risk of adverse events during follow-up.@*RESULTS@#The mean age of the patients was 73.8 ± 6.5 years and 57.2% were male. The median Society of Thoracic Surgeon-Predicted Risk of Mortality score was 6.0 (3.7-8.9). Regarding the aortic valve, the proportion of bicuspid aortic valve (BAV) was 48.5%. During the hospital stay, the stroke rate was 0.7%, and the incidence of high-degree atrioventricular block indicating permanent pacemaker implantation was 11.0%. The in-hospital all-cause mortality rate was 2.2%. After 1 year, the overall mortality rate was 4.5%. Compared to patients with tricuspid aortic valve (TAV), those with BAV had similar in-hospital complication rates, but a lower incidence of in-hospital mortality (1.4% vs. 3.3%) and 1 year mortality (2.3% vs. 5.8%).@*CONCLUSIONS@#TAVR candidates in China were younger, higher proportion of BAV, and had lower rates of post-procedural complications and mortality than other international all-comer registries. Given the use of early generation valves in the majority of the population, patients with BAV had similar rates of complications, but lower mortality than those with TAV. These findings further propel the extension of TAVR in low-risk patients.@*TRIAL REGISTRATION@#https://www.chictr.org.cn/ (No. ChiCTR2000038526).

ABSTRACT

Objective: To investigate the efficiency and safety of domestic tyrosine kinase inhibitor (TKI) dasatinib (Yinishu) as second-line treatment for patients with chronic myeloid leukemia in chronic phase (CML-CP). Methods: A retrospective analysis of clinical data of CML-CP patients who received domestic dasatinib as second-line treatment in the CML collaborative group hospitals of Hubei province from March 2016 to July 2018 was performed. The optimal response rate, the cumulative complete cytogenetic response (CCyR), the cumulative major molecular responses (MMR), progression free survival (PFS), event free survival (EFS) and adverse effects (AEs) of the patients were assessed at 3, 6 and 12 months of treatment. Results: A total of 83 CML-CP patients were enrolled in this study. The median follow-up time was 23 months. The optimal response rates at 3, 6 and 12 months in 83 CML-CP patients treated with dasatinib were 77.5% (54/71), 72.6% (61/75) and 60.7% (51/69), respectively. By the end of follow-up, the cumulative CCyR and MMR rates were 65.5% (55/80) and 57.1% (48/73), respectively. The median time to achieving CCyR and MMR was 3 months. During follow-up time, the PFS rate was 94.0% (79/83) and the EFS rate was 77.4% (65/83). The most common non-hematological AEs of dasatinib were edema (32.5%), rash itching (18.1%) and fatigue (13.3%). The common hematological AEs of dasatinib were thrombocytopenia (31.3%), leukopenia (19.3%) and anemia (6.0%). Conclusion: Domestic dasatinib was effective and safe as the second-line treatment of CML-CP patients and it can be used as an option for CML-CP patients.

ABSTRACT

Objective: To detect the expression of CRLF2 in adult Ph negative acute B lymphocytic leukemia (B-ALL) in newly diagnosed cases, and to investigate the relationship between CRLF2 and the general clinical characteristics, efficacy and prognosis. Methods: 103 cases of newly diagnosed adult B-ALL patients were investigated from Apr 2016 to Dec 2017 in the Department of Hematology, Henan Cancer Hospital. Bone marrow samples was used to detect the expression of CRLF2 in leukemic cells. The expression of CRLF2 ≥20% was defined as CRLF2-high group and <20% was defined as CRLF2-low group. The clinical characteristics and prognosis of the two groups were compared. Results: The Median overall survival (OS) and disease free survial (DFS) in CRLF2-high group were 9.0 months and 4.25 months, respectively. CRLF2-low group were 15.5 months and 10.25 months, respectively. There was a statistically significant difference in median OS and DFS between the two groups (P=0.007, P=0.000) . The 18-month OS and DFS in CRLF2-high group were 38.6% and 25.1%, respectively. CRLF2-low group were 57.8% and 42.3%, respectively. Multivariate analysis showed high expression of CRLF2 was an independent risk factor for OS (HR=2.991, 95% CI 1.429-6.261, P=0.004) and DFS (HR=2.374, 95%CI 1.146-4.960, P=0.041) in patients. Conclusion: Patients with high expression of CRLF2 had poor prognosis.

ABSTRACT

Objective To investigate the reliability and validity of a novel hand-held dynamometer, OE-210, for muscles strength of low-er extremities. Methods From March 1st to August 30th, 2016, 38 young adults were tested the muscle strength of quadriceps and ham-strings with OE-210 dynamometer by 2 rators, and were retested by one of the raters three days later. The isokinetic test was also conducted on all the subjects one day afterwards. The intraclass correlation coefficient (ICC) of OE-210 test results and the Pearson's correlation coeffi-cient between results of OE-210 and isokinetic test were calculated. Results The ICC of test-retest were 0.718 to 0.924, and the ICC of in-ter-rater were 0.784 to 0.870. The correlation between muscle performance measured with 2 tools were significant (P<0.001), that was light to medium on quadriceps (r=0.270-0.413), and strong on hamstrings (r=0.582-0.668). Conclusion OE-210 dynamometer was reliable for muscle strength measurement on quadriceps and hamstrings, and the conditions for valid application need further research.

ABSTRACT

Objective To analyze the causes for the thigh pain after treatment of femoral trochanteric fractures by proximal femoral nail antirotation Ⅱ( PFNA Ⅱ) . Methods Included in this ret-rospective study were 236 patients who had been treated by us for femoral trochanteric fracture from October 2011 to December 2015. They were 103 men and 133 women, aged from 42 to 86 years (average, 50. 3 years) . According to AO classification, 13 cases belonged to type 31-A1. 2, 32 to type 31-A1. 3, 35 to type 31-A2. 1, 27 to type 31-A2. 2, 33 to type 31-A2. 3, 38 to type 31-A3. 1, 39 to type 31-A3. 2 and 19 to type 31-A3. 3. All the fractures were single, fresh and closed and treated with PFNAⅡinternal fixation. Results This cohort was followed up for 8 to 26 months (average, 13. 2 months). Nonunion occurred in one case who had to accept artificial hip replacement. The remaining 235 cases obtained bony union after 22 to 39 weeks (average, 29. 3 weeks). By the Harris evaluation at final follow-ups, the affected hips scored from 81 to 93 points (average, 85. 1 points) . Post-operative thigh pain was reported in 19 cases (8. 05%) . The causes included varied anatomic morphology of the proximal femur in 6 cases, distal defects of the intramadullary nails in 4, insufficient stability of internal fixation or uneven biomecanical distribution in 3, unskillful operation in 2, and severe oesteoporosis in 4. Avascular necrosis of femoral head was not observed during follow-ups. Conclusions Postoperative thigh pain is worthy of serious atention from orthopaedists following PFNA Ⅱtreatment of femoral trochanteric fractures. PFNA Ⅱshould be modified according to the specific Chinese features of the proximal femur, especially in the respects of anterior arch and distal structure of the main nail and lateral declination as well.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the value of serum soluble transferrin receptor (sTfR) concentration in predicting early response to immunosuppressive therapy (IST) in severe aplastic anemia (SAA).</p><p><b>METHODS</b>Clinical data and hematologic responses of 140 SAA patients treated with rabbit antithymocyte globulin (rATG) combination with cyclosporine in our hospital were retrospectively analyzed. Correlation of pre-IST baseline of sTfR and IST responses was statistically analyzed and receiver operating characteristic (ROC) curve was used to estimate the sensitivity and specificity of sTfR in prediction of early responses.</p><p><b>RESULTS</b>Serum concentration of sTfR in very SAA (VSAA) patients were significantly lower than SAA and transfusion dependent non-SAA cases (P=0.001). The responders, especially at 3 months, had significantly higher pre- IST baseline of sTfR [median, 0.89 (range, 0.21-2.42) mg/L] than that [median, 0.58 (range, 0.13-1.88) mg/L] of non-responders (P=0.005). The cutoff level of 0.91 mg/L and 0.88 mg/L for predicting responses at 3 and 6 months were established based on the ROC curve, with the degree of accuracy of 65.0% and 60.7% respectively. Multivariate analysis showed that pre-IST baseline of sTfR was the independent factor of predicting response at 3 months (P=0.007) and at 6 months (P=0.021).</p><p><b>CONCLUSION</b>As a indicator of bone marrow failure severity, sTfR could predict early response to IST therapy in aplastic anemia.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the changes of displacement and stress in the model of lumbar pelvic and proximal femur during lumbar rotatory manipulation.</p><p><b>METHODS</b>The date of lumbar pelvic and proximal femur CT scan by Mimics 10.01 software was established a lumbar pelvic and proximal femur geometric model, then the model was modified with Geomagic 9, at last the modified model was imported into hypermesh 10 and meshed with tetrahedron, at the same time,add disc and ligaments. According to the principle of lumbar rotatory manipulation,the lumbar rotatory manipulation were decomposed. The mechanical parameters assigned into the three-dimensional finite element model. The changes of displacement and stress in the model of lunbar pelvic and proximal femur under the four conditions were calculated with Abaqus model of Hypermesh 10.</p><p><b>RESULTS</b>1) Under the same condition,the displacement order of lumbar was L1>L2>L3>L5 L5, anterior column > middle column > posterior column. 2) Under the different conditions, the displacement order of lumbar,case 3>case 1>case 4>case 2. 3) Under the same conditions, the displacement order of lumbar inter-vertebral disc from L1,2 to L5S1 was L1,2>L2,3>L3,4>L4,5>L5S1, as for the same inter-vertebral disc, the order was: second quadrant>third quadrant>first quadrant>fourth quadrant. 4) Under the different conditions,the displacement order of the inter-vertebral disc was L1,2>L2,3>L3,4>L4,5>L5S1, but to same inter-vertebral disc: case 3>case 4>case 1 >case 2. 5) There were apparent displacement and stress concentration in pelvis and hip during the manipulation.</p><p><b>CONCLUSION</b>1) The principles of lumbar rotation manipulation closely related to the relative displacement caused by rotation of various parts of lumbar pelvic and proximal femur model; 2) During the process of lumbar rotatory manipulation, the angle of lateral bending and flexion can not be randomly increased; 3) During the process of lumbar rotatory manipulation, all the conditions of lumbar pelvic and proximal femur must be considered to determine indications and contraindications.</p>

ABSTRACT

<p><b>BACKGROUND</b>High microvascular permeability plays an essential role in pathological process of multiple diseases such as septic shock, acute lung injury and acute respiratory distress syndrome, and burns. Inhibiting hyperpermeability is significant for controlling these conditions. Cdc42, as a main member of the small Rho GTPase family, plays a critical role in controlling and regulating the endothelial junctional permeability. We aimed to generate and identify endothelial specific cdc42-deficient mice by the Cre/loxp recombination approach, for examination in an animal model of the contribution of the cdc42 gene in the microvascular barrier function.</p><p><b>METHODS</b>We crossed cdc42(Flox/Flox) mice with mice expressing endothelial cell-specific Cre recombinase, and the offspring with the genotype cdc42(Flox/+)Tie2Cre(+/-) were back-crossed with the cdc42(Flox/Flox) mice. The cdc42(Flox/Flox)Tie2Cre(+/-) mice in the F2 generation were the target mice. If the cdc42 deficient mice did not survive, we would observe the cdc42 deficient mice embryos, and compare them with wild-type mice embryos.</p><p><b>RESULTS</b>Cdc42(flox/+)Cre(+/-) mice were mated with the cdc42(Flox/Flox) mice and among the living offspring there were no cdc42(Flox/Flox)Cre(+/-) target mice. We found the endothelial special cdc42 deficient embryos at the E7.5-E16.5 stage. We observed that cdc42 deficient embryos were much smaller, had fewer vessels and were a little more swollen compared with the wild-type embryos.</p><p><b>CONCLUSIONS</b>Endothelial specific knockout of cdc42 caused embryonic lethality and the mice did not survive to birth. The target embryos were much smaller, had fewer vessels and were a little more swollen compared with the wild-type embryos. These results demonstrated that the cdc42 plays an important role in development of embryos and in development of microvessels as well as microvascular permeability.</p>
