ObjectiveTo summarize the new biomarkers of deep venous thrombosis (DVT) and their research progress, so as to provide new ideas for the prevention, diagnosis and treatment of DVT. MethodThe literature about biomarkers of DVT in recent 5 years was reviewed and summarized. ResultsAccording to the results of literature review, a variety of common DVT biomarkers such as serum microrna, fibrin monomer, neutrophil capture net, and E-selectin were sorted out, but most of them had not been used in clinical DVT management. At present, the clinical diagnosis of DVT required the combination of positive D-dimer test and positive imaging examination, and there was no single biomarker for the diagnosis of DVT. ConclusionsBiomarkers are valuable in the diagnosis and treatment of DVT, but their sensitivity and specificity need to be optimized. Therefore, finding biomarkers with more diagnostic value is one of the future directions. At the same time, we also can consider fully combined with a variety of existing biomarkers, to improve the efficiency to the diagnosis of DVT.
ObjectiveTo summarize the research progress of ultrasmall superparamagnetic iron oxide (USPIO) enhanced magnetic resonance imaging (MRI) in normal-sized lymph node metastasis of colorectal cancer.MethodThe relevant literatures published recently at domestic and abroad about USPIO enhanced MRI in normal-sized lymph node metastasis of colorectal cancer were collected and reviewed.ResultsUSPIO, a kind of lymph node targeted magnetic resonance contrast agent, could be used to evaluate lymph node metastasis of malignant tumors. USPIO enhanced MRI could detect normal-sized lymph node metastasis in colorectal cancer effectively compared with normal MRI. It provided a higher diagnostic performance than normal enhanced MRI. In addition, USPIO enhanced MRI could also distinguish inflammatory and metastatic lymph nodes better that were difficult to be distinguished by normal enhanced MRI.ConclusionUSPIO enhanced MRI shows a certain potential for clinical application in detecting normal-sized lymph node metastasis of colorectal cancer, but it has not been widely used in China.

Objective To review the research progress of Schöttle’s method in medial patellofemoral ligament reconstruction (MPFLR), and provide the latest knowledge and suggestions for surgical treatment. Methods The studies on Schöttle’s method at home and abroad in recent years were extensively collected, then summarized the problems affecting the accuracy of Schöttle’s method and the new ideas to improve the accuracy of localization. Results It’s vital to accurately locate the femoral tunnel during MPFLR. Malposition of the femoral tunnel is the main cause of postoperative complications and surgical failure. Schöttle’s method is the most well studied and most reproducible method for femoral tunnel localization, which is widely used as the “gold standard”. However, there are still problems that affect the accuracy of Schöttle’s method, including the impact of the internal/external rotation and varus/valgus of the knee on localization accuracy, unclear requirements for X-ray imaging and anatomical landmark reference line drawing standards, no suitable for patients with anatomical variations, and lack of further research on pediatric patients. In recent years, some new ideas are proposed to improve the Schöttle’s method to improve the localization accuracy. ConclusionFuture research should combine new technologies such as three-dimensional (3D) printing and intraoperative navigation to develop personalized and intelligent Schöttle’s method, further improving their localization accuracy.
Serum marker Golgi protein 73 (GP73) is a type Ⅱ integral membrane protein located in cellular Golgi apparatus. GP73 not only processes proteins, but also participates in cell differentiation, intercellular signaling, and apoptosis. With the development of proteomics technology, GP73 has been used as a novel serum marker for detecting liver diseases. This article reviews the research progress of GP73 in the clinical diagnosis value and prognosis prediction of chronic hepatitis B in recent years, in order to provide new ideas for the diagnosis and treatment of patients with chronic hepatitis B.
Postoperative delirium is one of the most common postoperative complications in elderly patients, affecting the outcome of approximately half of surgical patients. The pathogenesis of postoperative delirium is still unclear, but multivariate models of the etiology of postoperative delirium are well-validated and widely accepted, and 40% of postoperative delirium can be effectively prevented by targeting predisposing factors. Benzodiazepines have long been considered as predisposing factors for postoperative delirium. Although benzodiazepines are widely used in clinical practice, most relevant guidelines recommend avoiding the use of benzodiazepines in the perioperative period to reduce the incidence of postoperative delirium. Controversy exists regarding the association of benzodiazepine use with postoperative delirium. This article discusses the results of studies on perioperative benzodiazepines and postoperative delirium.
ObjectiveTo summarize current widely-used therapies for cutaneous neurofibroma (cNF) and related research progress. MethodsBased on extensive investigation of domestic and foreign research, the existing treatment of cNF, including the indications, effectiveness and trials of targeted drugs were reviewed. ResultscNF is a hallmark feature of neurofibromatosis type 1 and has a dramatic negative impact on patient appearance and quality of life. At present, there is no standard management of cNF. Invasive treatment is a commonly-used treatment. Surgical removal gives excellent cosmetic results, but it is difficult for multiple tumors; CO2 laser ablation, laser photocoagulation, electro-drying, and radiofrequency ablation are effective in treating lots of cNF at one time. Although fast and effective, these therapies can lead to depigmentation, hyperpigmentation, or extensive scarring. There is no targeted drug approval for cNF, and a series of studies have been carried out on the Ras-MEK pathway, Ras-mTOR pathway, receptor tyrosine kinase, et al. ConclusionThe treatment of cNF has developed rapidly in recent years and has broad prospects, but the individualization and precision of the treatment still needs further clinical research.
Objective To review the advances in double-bundle anterior cruciate ligament (ACL) reconstruction in adolescents at home and abroad. Methods Recent literature about double-bundle ACL reconstruction in adolescents at home and abroad was extensively consulted, and the relationship between bone canal and epiphyseal plate, clinical verification of surgical safety, and clinical effectiveness of double-bundle ACL reconstruction in adolescents were summarized and analyzed. Results Double-bundle ACL reconstruction has certain advantages in clinical stability and re-rupture rate when compared with single-bundle ACL reconstruction in adolescents, and there is no significant difference in safety between them. Conclusion Double-bundle ACL reconstruction in adolescents can achieve lower re-rupture rate and better stability when compared with single-bundle reconstruction. However, the sample size of clinical research is too small, and the follow-up time is too short, so the effectiveness needs to be continuously observed.
Knee osteoarthritis (KOA) is one of the common degenerative joint diseases, which is more common in the middle-aged and elderly population. It shows significant gender differences, with a significantly higher incidence rate in women than in men, seriously affecting the quality of life of patients. However, there are few research reports on the correlation between gender differences and the incidence of KOA both domestically and internationally. Therefore, this article will summarize and analyze the potential causes of gender differences related to the incidence of KOA from five aspects: hormone levels, anatomical biomechanical characteristics, genes, obesity, and exercise-muscle factors. Through a comprehensive review of research progress, the aim is to provide a theoretical basis for gender based personalized treatment of KOA in clinical practice.
Objective To summarize the research status and prospect of immunotherapy for biliary tract cancer (BTC). Method The literatures about immunotherapy of BTC at home and abroad in recent years were reviewed. Results Surgical resection was still the first choice and only radical treatment for BTC. However, the recurrence rate of BTC was high, and most of the patients were in the middle and late stage with metastasis and lose the opportunity of operation. Patients with local progression, metastasis or recurrence could only receive chemotherapy and other comprehensive treatment, but they could not get satisfactory results. The continuous update of targeted drugs brings new hope for drug therapy of BTC, and immunotherapy had become a new treatment of tumor targeted therapy following radiotherapy and chemotherapy. ConclusionImmunotherapy can be used as an option for the treatment of advanced BTC and its postoperative recurrence and metastasis, and has attracted more and more attention.
