A Sport Monitoring System Based on the Optimized Adaptive Fuzzy PID Control Algorithm in OneNet Internet of Things and Cloud Platform.

Aiming at some problems existing in the existing sports monitoring system, based on the joint action of OneNet Internet of Things (IoT) and cloud platform, an optimized adaptive fuzzy PID control algorithm is adopted to monitor and analyze sports. Finally, the accuracy of the optimization model is verified through the comparison of different models, and the algorithm is used to predict and analyze sports. The research shows that (1) as the index calculation of cloud platform shows, with the increase of iteration time, the change curve of relevant indexes can be divided into four different stages, namely, rapid fluctuation stage, slow decline stage, slow fluctuation stage, and rapid decline stage. (2) The conventional calculation method (CPID) cannot well describe the change rule of the test data in the early stage of settlement. The fuzzy adaptive calculation method (NPID) also exposes some errors in the fitting and description of the test curve in the calculation process, while the improved adaptive calculation method (GPID) can describe the change characteristics and rules of the test curve well for different stages. (3) Compared with the original model, the optimization model can better describe the first and second stages of index change, indicating the accuracy of the optimization model. And the algorithm can be used to predict and analyze the changes of indicators and sports monitoring better, and the analysis results can provide relevant guidance for sports monitoring. This optimization scheme provides basis and theoretical support for the application of OneNet IoT and cloud platform.

Effects of Different Physical Exercises on Physical and Mental Health of Female College Students.

Objective: To explore the effects of different physical exercises on the physical and mental health of female college students. Methods: This study focuses on the influence of sports intervention on the physical and mental health of female college students in H University. With the methods of literature review, investigation, measurement, experiment, and mathematical statistics, this paper discusses the influence of different physical exercises on the physical and mental health of female college students in H University. Results: The average total score of female college students' health status is 10.25, which is between the average level of L 0.34-10.72 in some universities in China. Before and after the experiment, there were significant differences in five dimensions of self-respect, balance of personality structure, natural intimacy, belief value, and ideal transcendence among all female college students in the aerobics option group. Basketball exercises have significant effects on female college students' sense of unity of body and mind, self-structure coordination, interpersonal affinity, natural affinity, belief value, self-respect, and role adaptation. Compared with before and after taking part in table tennis exercise, the mental health level of girls has significant differences in four dimensions: self-respect, balance of personality structure, interpersonal affinity, and natural affinity. Conclusion: Different physical exercises have a significant impact on female college students' physical and mental health, can improve their physical health, and have no significant impact on their social adaptability.

Malignant mesothelioma of the greater omentum mimicking omental infarction: a case report.

Mesothelioma develops most commonly in the pleura, and less frequently in the peritoneum. Usually, it manifests as diffuse peritoneal thickening and multiple nodules, and rarely as a solitary mass. We report a rare case of primary malignant mesothelioma of the greater omentum, which mimicked omental infarct. A 54-year-old Korean man was admitted because of severe abdominal pain of sudden onset. A tender mass with indistinct margins was palpated in the upper abdomen. Abdominal ultrasound and computed tomography showed an ill-defined mass in the greater omentum and little ascites in the peri-hepatic space, and neutrophil-dominant exudates were documented on paracentesis. Intravenous antibiotics and analgesics were given for omental infarction with superimposed infection, which resulted in symptomatic improvement. The imaging studies after a week revealed a growing mass and ascites. Laparoscopic surgery was performed and an 8 cm x 3.3 cm greater omental mass was found, with multiple small nodules on the peritoneum, diaphragm, and pelvic cavity wall. Histological examination showed proliferating malignant epithelioid cells that stained strongly for calretinin, which was compatible with malignant mesothelioma. We recommend that primary omental mesothelioma should be included in the differential diagnosis of patients with omental infarction, despite its rarity.

Overexpression of metastasis-associated protein 2 is associated with hepatocellular carcinoma size and differentiation.

BACKGROUND AND AIM: Metastasis is a multistep event in which neoplastic cells detach from the tumor, migrate, disseminate, extravasate, and eventually proliferate at the secondary distant sites. Hepatocellular carcinoma (HCC) is characterized by hypervascularity and frequent metastasis. Recently, metastasis-associated proteins were identified and named metastatic tumor antigens (MTA) 1, 2, and 3. They have been found to be contained in the nucleosome remodeling and histone deacetylase complex. MTA2 has been reported to interact with p53 and inhibit p53-mediated cell growth arrest and apoptosis by deacetylation. Although it has been reported that the expression of MTA1 is related to tumor progression and metastasis, it is still unclear how MTA2 is involved in HCC. In this study, we found that the overexpression of MTA2 is associated with HCC size and differentiation after hepatectomy. METHODS: The expression of MTA2 was examined in 506 human HCC samples that underwent hepatic resection using tissue microarray. The expression of MTA2 was classified into 0, 1, 2, and 3, based on immunoreactivity. RESULTS: The expression of MTA2 was predominantly localized to the nucleus. MTA2 was detected in 487 (96.2%) of the 506 human HCC samples. Notably, the MTA2 expression level strongly increased depending on the size and differentiation of HCC. CONCLUSIONS: These findings indicate a tight correlation between the MTA2 expression level and HCC size and differentiation. Therefore, MTA2 might be a predictor of aggressive phenotypes and a possible target molecule for anticancer drug design in human HCC.

Metastatic tumor antigen 1 is closely associated with frequent postoperative recurrence and poor survival in patients with hepatocellular carcinoma.

Metastatic tumor antigen 1 (MTA1) is known to play a role in angiogenic processes as a stabilizer of hypoxia-inducible factor 1-alpha (HIF1-alpha). In this study, we examined whether overexpression of MTA1 affects the recurrence of hepatocellular carcinoma (HCC) after surgical resection and the survival of the patients. A total of 506 HCC patients who underwent hepatic resection were included in the study. They were followed up for a median of 43 months (range, 1-96 months) after hepatectomy. MTA1 expression levels were determined by the proportion of immunopositive cells (none, all negative; +, <50%; ++, >50%). The relationships between MTA1 expression and the HCC histological features, the appearance of recurrent HCC after surgical resection, and the survival of the patients were examined. Eighty-eight cases (17%) of the HCCs were positive for MTA1, although the surrounding liver tissues were all negative for MTA1; 62 cases were + and 26 cases were ++. Increased MTA1 expression levels in HCC were correlated with larger tumors (P = 0.04), perinodal extension (P = 0.03), and microvascular invasion (P = 0.008). Histological differentiation had marginal significance (P = 0.056). However, there was no association between MTA1 expression and age, sex, Child-Pugh class, and capsule invasion of HCC. Interestingly, MTA1 expression levels were significantly greater in hepatitis B virus (HBV)-associated HCC compared with hepatitis C virus (HCV)-associated HCC (P = 0.017). The cumulative recurrence rates of MTA1-positive HCCs were markedly greater than those of MTA1-negative HCCs (P < 0.0001). The cumulative survival rates of patients with MTA1-positive HCCs were significantly shorter than those of patients with MTA1-negative HCCs (P < 0.0001). In conclusion, our data indicate that MTA1 is closely associated with microvascular invasion, frequent postoperative recurrence, and poor survival of HCC patients, especially in those with HBV-associated HCC.
