Comprehensive evaluation methods are generally used to assess the population data. When we need to estimate the sample data in special situations, the impacts brought by the sampling error should be considered. Due to lack of the accurate measurement for the sensitivity and stability in the comprehensive evaluation methods, sampling errors usually cannot be estimated in the sampling research. Monte Carlo simulation was used in this article to solve the probability of the ordering results, and the matlab programs were presented. Based on the simulated results, we change the conventional “absolute conclusion” of comprehensive evaluation methods to “probability results” for the sample data, and put forward a new sorting and ranking method for the results of comprehensive evaluation.

The quality of medical care shows characteristics of dynamic state with changes in time. However, many of appraisal and evaluation projects usually keep on the status of "past" or "present". Most of these models are static evaluation approach. In this study, besides the "past" and "present" status, we took one step further to unveil the future development trends of the medical therapeutical effects. Based on the index value and index increment, a dynamic TOPSIS method is presented. This method pays attention to both transverse and lengthwise information and can not only perform the evaluation on each time section but also can make the final dynamic evaluation. We applied this new method to the evaluation of quality of medical care, which was proved to be effective.

The TOPSIS method is a static comprehensive evaluation method for wide range applications. However, it encounters the reverse order problem in practical applications. Moreover, its evaluation value Ci only reflects the relative proximity of each evaluation object inside but not to the degree of closeness to the ideal optimal solution. The evaluation value is also limited to distinguish between the ranges of merit ranking. Since TOPSIS method has the wide range of applications, it is necessary to overcome the drawbacks of TOPSIS method. This article proposes a new improved TOPSIS method, which shows strict isotonicity and is more sensitive than the traditional TOPSIS method. The medical application based on this improved TOPSIS method is introduced.

OBJECTIVE: To compare the efficacy of proximal femoral nail anti-rotation (PFNA) versus dynamic hip screw (DHS) in the treatment of trochanteric fractures in adults. METHODS: Reports of studies using randomized controlled trials (RCT) to compare PFNA with DHS in the management of intertrochanteric fractures were retrieved (up to December 5, 2011) from the Cochrane Library, MEDLINE, Elsevier, the Chinese Biomedical Database, Wanfang Data,and manually. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software Revman? 5.0 was used for data-analysis. RESULTS: Thirteen RCTs involving 958 cases were included in the Meta-analysis. The results showed that, compared with DHS, PFNA significantly decreased the duration of surgery [WMD = -21.38, 95%CI (-33.05,-9.26), P<0.05], intra-operative blood loss [WMD = -176.36, 95%CI (-232.20, -120.52), P<0.05], the rate of post-operative complication [RR=0.46, 95%CI (0.31, 0.70), P<0.05], the rate of post-operative fixation failure[RR=0.27, 95%CI(0.11,0.62), P<0.05]. CONCLUSION PFNA for intertrochanteric fractures is superior to DHS in regards to the mean duration of surgery, mean intra-operative blood loss, the rate of post-operative complication, and the rate of post-operative fixation failure. But there is not enough evidence to show any difference between PFNA and DHS in regards to the mean duration of hospital, the mean duration of fracture healing, the rate of post-operative fracture, the rate of post-operative coxa vara, the rate of postoperative superficial wound infection, the rate of other post-operative complications or the Harris score after surgery.

BACKGROUND: Knee osteoarthritis (KOA) is a prevalent chronic joint disease caused by various factors. Mesenchymal stem cells (MSCs) therapy is an increasingly promising therapeutic option for osteoarthritis. However, the chronic inflammation of knee joint can severely impede the therapeutic effects of transplanted cells. Gelatin microspheres (GMs) are degradable biomaterial that have various porosities for cell adhesion and cell–cell interaction. Excellent elasticity and deformability of GMs make it an excellent injectable vehicle for cell delivery. METHODS: We created Wharton’s jelly derived mesenchymal stem cells (WJMSCs)-GMs complexes and assessed the effects of GMs on cell activity, proliferation and chondrogenesis. Then, WJMSCs loaded in GMs were transplanted in the joint of osteoarthritis mice. After four weeks, joint tissue was collected for histological analysis. Overexpressing-luciferase WJMSCs were performed to explore cell retention in mice. RESULTS: In vitro experiments demonstrated that WJMSCs loaded with GMs maintained cell viability and proliferative potential. Moreover, GMs enhanced the chondrogenesis differentiation of WJMSCs while alleviated cell hypertrophy. In KOA mice model, transplantation of WJMSCs-GMs complexes promoted cartilage regeneration and cartilage matrix formation, contributing to the treatment of KOA. Compared with other groups, in WJMSCs+GMs group, there were fewer cartilage defects and with a more integrated tibia structure. Tracking results of stable-overexpressing luciferase WJMSCs demonstrated that GMs significantly extended the retention time of WJMSCs in knee joint cavity. CONCLUSION Our results indicated that GMs facilitate WJMSCs mediated knee osteoarthritis healing in mice by promoting cartilage regeneration and prolonging cell retention. It might potentially provide an optimal strategy for the biomaterial-stem cell based therapy for knee osteoarthritis.

The European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) have recently updated and published the 2024 ESC guidelines for the management of atrial fibrillation. Based on the latest evidences, the guidelines have been updated in many aspects, such as diagnostic criteria for atrial fibrillation, AF-CARE treatment principles, comorbidities and risk factor management. In particular, there are significant changes in the recommendations for surgical management of atrial fibrillation in the guidelines. Therefore, this paper aims to interpret the content updates of the guidelines in AF-CARE treatment principles, diagnostic criteria and surgical treatment of atrial fibrillation, especially highlighting the updates and new suggestions about surgical treatment of atrial fibrillation.

Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
