Abstract: Intravenous leiomyomatosis (IVL) is a rare kind of uterine myoma. It is a benign smooth muscle tumor with invading growth pattern. The tumor extends into venous channels, but rarely invades tissues. It grows along the refluxing direction of the venous channels, uterine vein, ovarian vein, and beyond the uterus, extends into the inferior vena cava till the right atrium or pulmonary arteries, resulting in intracardiac leiomyomatosis (ICL). At present, the tumor can be detected by ultrasonic waves, computer tomography and magnetic resonance imaging. The main ICL therapy is surgery which is divided into onestage operation and twostage operation in which the key is the complete tumor excision. Most sufferers have a good prognosis, but there are possibilities of recurrence. Missed diagnosis and misdiagnosis are not uncommon, because the disease is rare with hided and diversified clinical manifestations. It is fatal without special characteristics. For a better understanding of ICL, the recent research and treatment of ICL are reviewed.
ObjectiveTo conclude the current status and research progress on the pathological mechanism, development and management of pancreatic cancer-associated diseases and provide evidence for intervention of such diseases.MethodThe relevant literatures were reviewed, and the research progress on pancreatic cancer-associated diseases were summarized.ResultsThere are many types of pancreatic cancer-associated diseases, and common diseases included pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, diabetes, and chronic pancreatitis. Although management and following-up about this kind of diseases remain controversial, the basic consensus has been reached.ConclusionAdequate follow-up is required for patients with pancreatic cancer-associated disease, individualized interventions should be taken if necessary.
Electroencephalography (EEG) signals are strongly correlated with human emotions. The importance of nodes in the emotional brain network provides an effective means to analyze the emotional brain mechanism. In this paper, a new ranking method of node importance, weighted K-order propagation number method, was used to design and implement a classification algorithm for emotional brain networks. Firstly, based on DEAP emotional EEG data, a cross-sample entropy brain network was constructed, and the importance of nodes in positive and negative emotional brain networks was sorted to obtain the feature matrix under multi-threshold scales. Secondly, feature extraction and support vector machine (SVM) were used to classify emotion. The classification accuracy was 83.6%. The results show that it is effective to use the weighted K-order propagation number method to extract the importance characteristics of brain network nodes for emotion classification, which provides a new means for feature extraction and analysis of complex networks.
In order to promote the effective development of hospital day surgery mode, a construction method of information management platform that meets the characteristics of day surgery mode is presented. By analyzing the business process of the day surgery mode, the system architecture of the information platform is given; according to the difficulty of the surgical scheduling, the two-stage surgical scheduling algorithm based on the ranking theory is given; by analyzing the day surgery data statistically, a multi-angle surgical index analysis module is provided. The information management of the day surgery mode has been realized, and the work efficiency has been improved. A reasonable day surgery information platform construction can help to optimize the daytime surgical procedure and promote the smooth development of day surgery.
ObjectiveTo compare clinical efficacy between transumbilical three-port laparoscopic surgery (TU-TPLS) and transumbilical single-incision laparoscopic surgery (TU-SILS) in repair of acute peptic ulcer perforation. MethodsThe patients with acute peptic ulcer perforation who underwent TU-TPLS or TU-SILS in Chengdu Second People’s Hospital Affiliated to Sichuan University from January 2022 to December 2024 were retrospectively collected, and then were divided into the TU-TPLS group and TU-SILS group. The operation time, postoperative 24 h incision pain score (visual analogue scale) , postoperative hospital stay, total hospitalization cost, incision scar score (Vancouver scar scale), comprehensive satisfaction, and postoperative complications were compared between the two groups. ResultsA total of 105 patients met the inclusion criteria were enrolled, comprising 50 patients in the TU-TPLS group and 55 patients in the TU-SILS. There were no statistically significant differences in baseline characteristics between the two groups, such as gender, age, body mass index, perforation site, perforation diameter, and Boey score (all P>0.05). Postoperatively, the TU-TPLS group demonstrated significantly lower visual analogue scale pain score at 24 h compared to the TU-SILS group [(2.34±0.63) score vs. (3.22±1.05) score, P<0.001] and significantly higher comprehensive satisfaction score [(7.60±0.86) score vs. (7.02±1.01) score, P=0.002]. However, no statistically significant differences were observed between the TU-TPLS group and TU-SILS group regarding operative time [(71.84±10.51) min vs. (69.78±7.98) min, P=0.257], postoperative hospital stay [(10.35±2.08) d vs. (9.96±1.75) d, P=0.310], or total hospitalization costs [(20 856.23±4 095.73) yuan vs. (19 988.83±2 933.43) yuan, P=0.212]. The incidence of umbilical wound infection was 1 case in the TU-TPLS group and 3 cases in the TU-SILS group (P=0.619). Postoperative residual intra-abdominal infection occurred in 2 cases in the TU-TPLS group and 1 case in the TU-SILS group (P=0.604). Incisional bleeding occurred in 0 case in the TU-TPLS group and 1 case in the TU-SILS group (P>0.999). Furthermore, there was no statistically significant difference in the scar assessment score between the TU-TPLS group and TU-SILS group [(3.11±1.13) score vs. (2.92±0.70) score, P=0.301] at the 2-month postoperative follow-up. ConclusionsBoth TU-TPLS and TU-SILS have achieved good therapeutic effects in treatment of acute peptic ulcer perforation. However, TU-TPLS has more advantages over TU-SILS. TU-TPLS causes milder incision pain, leads to higher patient satisfaction, and does not require special equipment.
