How to accurately identify factors of cancer occurrence and to provide intervention early are the key issues that urgently need to be addressed in cancer prevention and treatment. Mendelian randomization (MR) analysis uses genetic variants as instrument variables for exposures of interest, which compensates the shortcomings of traditional observational studies and clinical trials. This review introduced the current application status of MR analysis in cancer etiology and treatment researches in details, including assessment of cancer risk factors, exploration of cancer treatment targets, and evaluation of drug efficiency and adverse reactions. The scopes and dimensions of cancer etiology and treatment researches are greatly expanded because of various MR designs and abundant high-level omics data. As well, it provides a practical and feasible method for constructing cancer etiology networks and drug targeted databases, which are promising for supporting the development of precision cancer prevention and treatment.
In 2022, there were 367.7 thousands new cases and 316.5 thousands deaths of primary liver cancer in China. Radiofrequency ablation (RFA) is one of the radical treatments for liver cancer. It has the characteristics of definite curative effect, minimal invasion and low cost. In patients with early liver cancer, the curative effect is similar to surgical resection. The concept and practice of precision surgery provide new ideas for improving the efficacy of RFA. Based on the RFA treatment experience of more than ten thousand cases, the author’s team has carried out research on the precise ablation treatment of primary liver cancer. Now, the author will combine the existing literature and our team’s experience to discuss the application and prospect of the precise surgery concept in RFA treatment.
Exercise intervention is an important non-pharmacological intervention for various diseases, and establishing precise exercise load assessment techniques can improve the quality of exercise intervention and the efficiency of disease prevention and control. Based on data collection from wearable devices, this study conducts nonlinear optimization and empirical verification of the original "Fitness-Fatigue Model". By constructing a time-varying attenuation function and specific coefficients, this study develops an optimized mathematical model that reflects the nonlinear characteristics of training responses. Thirteen participants underwent 12 weeks of moderate-intensity continuous cycling, three times per week. For each training session, external load (actual work done) and internal load (heart rate variability index) data were collected for each individual to conduct a performance comparison between the optimized model and the original model. The results show that the optimized model demonstrates a significantly improved overall goodness of fit and superior predictive ability. In summary, the findings of this study can support dynamic adjustments to participants' training programs and aid in the prevention and control of chronic diseases.
This study systematically explores the assessment tools for balance function in elderly patients after total hip arthroplasty and their clinical applications, while also envisioning future trends toward multidimensional integration and intelligent development. By summarizing the commonly used subjective and objective assessment in clinical practice and analyzing the application of these methods in preoperative prehabilitation and postoperative rehabilitation monitoring for elderly total hip arthroplasty patients, this article proposes that future efforts should focus on promoting the integration of subjective and objective assessment, developing intelligent predictive models, and establishing closed-loop rehabilitation systems to enhance the precision and effectiveness of assessment and rehabilitation.
Objective To explore the application value of time of flight magnetic resonance angiography (TOF-MRA) in target bypass surgery for moyamoya disease. Methods The data of patients with moyamoya disease in Affiliated Drum Tower Hospital, Medical College, Nanjing University between May 1 and August 30, 2020 were retrospectively analyzed. Patients were divided into navigation group and control group according to whether navigation technology was used during operation. All patients completed TOF-MRA evaluation before operation, and all patients completed surgical treatment. One week after operation, TOF-MRA was reviewed to evaluate the patency of anastomotic stoma. The intraoperative and postoperative conditions of the two groups were compared. Results Finally, 48 patients with moyamoya disease were included. 22 patients who used intraoperative navigation were included in the navigation group, and 26 patients with moyamoya disease who did not use intraoperative navigation in the same period were included in the control group. There was no significant difference between the two groups in gender, age, Suzuki stage before operation, proportion of posterior circulation involvement, proportion of bleeding type, proportion of hypertension and proportion of diabetes (P>0.05). The operation duration [(3.3±0.4) vs. (3.6±0.6) h] and postoperative hospital stay [(7.3±1.9) vs. (8.8±2.7) d] in the navigation group were shorter than those in the control group (P<0.05). There was no significant difference between the two groups in the proportion of patients who completed bypass surgery, the proportion of middle meningeal artery retained, the postoperative patency rate, the proportion of temporary dysfunction, and the proportion of serious complications (P>0.05). Conclusion TOF-MRA sequence combined with navigation technology can effectively guide the surgical scheme design and postoperative evaluation of moyamoya disease.
Liddle syndrome and Gordon syndrome are two rare single-gene inherited hypertension diseases. In patients≤40 years, the prevalence of Liddle syndrome is about 1% and Gordon syndrome is uncertain all over the word, for which is often misdiagnosed and mistreated. The therapies of those diseases are targeted at gene mutation sites, as well as combined with modified lifestyle, and can achieve satisfactory diseases control. This paper reports a patient who is diagnosed with Liddle syndrome and Gordon syndrome at the same time. We aimed to consolidate and improve the diagnosis and accurate treatment of those two diseases by sharing, studying and discussing together with clinical doctors.
The global incidence of benign biliary tract diseases is high. Not only its anatomical variations are complex and the disease heterogeneity is strong, but also its preoperative assessment methods, surgical techniques and diagnostic and treatment strategies need to be improved. Consequently, patients have many perioperative complications and a poor long-term prognosis. According to the anatomical characteristics of the biliary tract and the pathophysiological characteristics of benign biliary diseases, we propose the surgical treatment concept of benign biliary tract diseases with the removal of the diseased bile duct tree drainage as the core, which is different from the traditional biliary surgery that takes “patency and obstruction” as the focus of treatment, and “alleviates symptoms” as the treatment goal. Through a series of improvements such as preoperative evaluation, surgical planning, surgical operations, and postoperative management, we have designed a series of innovative diagnosis and treatment strategies and procedures with the goal of curing biliary diseases, with a view to changing the diagnosis and treatment status of biliary surgery. We hope that can change the current the diagnosis and treatment status of biliary surgery.
Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disease caused by the mutations in the NF1 gene, with an incidence of approximately 1/3 000. Affecting multiple organs and systems throughout the body, NF1 caused a wide variety of clinical symptoms. A comprehensive multidisciplinary diagnostic and treatment model is needed to meet the diverse needs of NF1 patients and improve their quality of life. In recent years, the emergence of targeted therapies has further benefited NF1 patients, and the number of clinical consultations has increased dramatically. However, due to the rarity of the disease itself and insufficient attention previously, the standardized, systematic, and precise diagnosis and treatment model of NF1 still needs to be further improved. In this paper, we reviewed the current status of comprehensive diagnosis and treatment of NF1 in China, combine with our long-term experiences in diagnosis and treatment of this disease. Meanwhile, we propose future directions and several suggestions for the comprehensive diagnosis and treatment model for Chinese NF1 patients.
