Abstract
The pace of modern life is accelerating, the pressure of life is gradually increasing, and the long-term accumulation of mental fatigue poses a threat to health. By analyzing physiological signals and parameters, this paper proposes a method that can identify the state of mental fatigue, which helps to maintain a healthy life. The method proposed in this paper is a new recognition method of psychological fatigue state of electrocardiogram signals based on convolutional neural network and long short-term memory. Firstly, the convolution layer of one-dimensional convolutional neural network model is used to extract local features, the key information is extracted through pooling layer, and some redundant data is removed. Then, the extracted features are used as input to the long short-term memory model to further fuse the ECG features. Finally, by integrating the key information through the full connection layer, the accurate recognition of mental fatigue state is successfully realized. The results show that compared with traditional machine learning algorithms, the proposed method significantly improves the accuracy of mental fatigue recognition to 96.3%, which provides a reliable basis for the early warning and evaluation of mental fatigue.

Abstract
OBJECTIVE To evaluate the effects of Yifei Sanjie Pills (YFSJ) on weight, strength, pathology, glycogen and lipid contents and metabolism of skeletal muscles in tumor-bearing mice and explore the therapeutic mechanism of YFSJ for cancer-related skeletal muscle atrophy. METHODS Sixteen female ICR mice bearing intraperitoneal Lewis lung adenocarcinoma xenografts were randomized into model group and YFSJ treatment group (daily dose of 4 g/kg for 21 days, n=8), with another 8 normal mice as the normal control group. The changes in body weight and gastrocnemius muscle weight of the mice were recorded. Liquid chromatography-mass spectrometry (LC-MS) was used to analyze the drug components in YFSJ entering the blood. Enzyme-linked immunosorbent assay was used to detect serum blood glucose and insulin concentrations and inflammatory cytokine levels in the serum and gastrocnemius. RNA-seq was performed to analyze the signaling pathways involved in the pathologies of the gastrocnemius muscle, and lipid contents in the muscle were observed using Oil red O staining. Adenosine triphosphatase staining was used to assess the metabolic intensity of the gastrocnemius muscle, and inflammatory cell infiltration and P-AKT level were evaluated using immunohistochemical staining; the contents of creatine kinase, lactate dehydrogenase and myoglobin in the gastrocnemius muscle were also detected. RESULTS Treatment with YFSJ significantly increased skeletal muscle strength and gastrocnemius muscle weight (P < 0.001) and reduced the levels of gastrocnemius muscle injury markers in the tumor-bearing mice (P < 0.01). RNA-seq and LC-MS showed that YFSJ alleviated gastrocnemius muscle injury in the tumor-bearing mice possibly by improving inflammatory infiltration, insulin resistance and lipid metabolism (P < 0.05). YFSJ lowered inflammatory cytokine levels in both the serum and gastrocnemius muscle (P < 0.05), reduced pro-inflammatory cell infiltration, increased P-AKT level, and improved glycogen and lipid contents and metabolic levels in the gastrocnemius muscle. CONCLUSION YFSJ alleviates cancer-related skeletal muscle atrophy possibly by reducing inflammatory insulin resistance.

Abstract
Objective Tunneled-cuffed catheters (TCCs) are frequently used for establishing hemodialysis access for maintenance hemodialysis in older patients with exhausted resources of peripheral vessels. Fibrin sheath formation around the catheter is one of the most common complications of long-term use of indwelling catheter, which may cause the malfunction of the catheter. In this study, we intend to compare the prognosis of two catheter replacement methods, in situ replacement and replacement through a fibrin sheath crevice, with both being assisted by balloon dilation, and to explore the optimal catheter replacement process. Methods A retrospective study was conducted with 52 patients who underwent a replacement of their TCCs. Among them, 27 cases had their TCC replaced by the modified method of replacement through a fibrin sheath crevice and were referred to as the sheath crevice group, while 25 cases underwent in situ catheter replacement and were referred to as the in situ group. The primary outcome indicators included maximum blood flow in hemodialysis catheter and the urea clearance rate calculated by Kt/V values at the 1, 3, and 6-month follow-ups. The secondary outcomes included dialyzer alarms being set off and catheter-related infections during follow-up. Results There was no significant difference between the general data of the two groups. There was no massive blood loss during the replacement procedure. Neither were there cardiac tamponade, catheter-associated infections, or other complications. Follow-ups were made 1, 3, and 6 months after the replacement procedure. The sheath crevice group had higher catheter blood flow and Kt/V values at the 6-month follow-up than the in situ group did ([241.85±9.62] mL/min vs. [234.40±11.21] mL/min, P=0.014 and 1.31±0.55 vs. 1.27±0.49, P=0.005, respectively). During the follow-up process, access alarms were reported in 5 patients (three in the in situ group and two in the sheath crevice group) during dialysis. No catheter-associated infection occurred in either group. Conclusion The catheter replacement method of balloon dilation-assisted catheter insertion through a fibrin sheath crevice is safe and effective, resulting in better long-term catheter blood flow compared with that of in situ catheter replacement.

Abstract
OBJECTIVES To examine the serum level of free fatty acid (FFA) in children with primary hypertension and its value in the pathogenesis, prevention, and treatment of primary hypertension in children. METHODS In this retrospective study, 34 children with primary hypertension who were treated for the first time in Children's Hospital Affiliated to Capital Institute of Pediatrics from January to June, 2021, were enrolled as the hypertension group, and 32 children with normal blood pressure who underwent physical examination during the same period were enrolled as the control group. The two groups were compared in terms of the levels of fasting serum FFA, fasting serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C). The multivariate logistic regression model was used to analyze the influence of FFA on the development of primary hypertension. RESULTS Compared with the control group, the hypertension group had significantly higher body mass index (BMI), systolic blood pressure, and diastolic blood pressure (P<0.05), as well as significantly higher serum levels of FFA, TG, LDL-C, and non-HDL-C and a significantly lower serum level of HDL-C (P<0.05). Compared with the control group, the hypertension group had significantly higher rates of elevated serum FFA (>0.45 mmol/L for girls and >0.60 mmol/L for boys) (P<0.05) and abnormal blood lipid levels (abnormality in at least one index among serum TG, TC, LDL-C, HDL-C, and non-HDL-C) (P<0.05). A multivariate logistic regression equation was established based on age, sex, BMI, elevated serum FFA, and abnormal blood lipid levels, and the results showed that elevated serum FFA was an independent risk factor for primary hypertension in children (OR=17.560, 95%CI: 1.964-157.003, P<0.05). CONCLUSIONS There is a significant increase in serum FFA level in children with primary hypertension, and the increase in serum FFA can increase the risk of primary hypertension in children.

Abstract
OBJECTIVES To study the distribution characteristics of methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism in children with primary hypertension, and to explore the association between MTHFR C677T gene polymorphism and H-type hypertension in children. METHODS A total of 121 children with primary hypertension who were hospitalized in the department of cardiovascular medicine from January to July 2021, newly diagnosed, and untreated were retrospectively selected as the subjects. The children were divided into three groups: CC genotype (19 children), CT genotype (51 children), and TT genotype (51 children). According to the serum homocysteine (Hcy) level, they were divided two groups: H-type hypertension (47 children) and simple hypertension (74 children). The medical data were compared between the groups. The association between MTHFR C677T gene polymorphism and H-type hypertension was evaluated. RESULTS The mutation frequency of T allele in children with primary hypertension was significantly higher than that in healthy adults in Beijing and Chinese Han adults (P<0.001). The serum Hcy level in the TT genotype group was significantly higher than that in the CC and CT genotype groups (P<0.001). The serum Hcy level in the H-type hypertension group was significantly higher than that in the simple hypertension group (P<0.001), and MTHFR C677T was mostly TT genotype, which was associated with the risk of H-type hypertension (OR=12.71, P<0.001). There was no significant difference in the incidence rate of target organ damage between the H-type hypertension and simple hypertension groups (P>0.05). However, multiple organ involvement was observed in the H-type hypertension group at diagnosis, accounting for 11% (5/47). CONCLUSIONS The mutation rate of MTHFR C677T T allele in children with primary hypertension is high and associated with the serum Hcy level. TT genotype is an independent risk factor for H-type hypertension in children, and it may be related to the severity of early target organ damage.
