Objective To explore the changes in trace elements and amino acid profiles in serum of patients with hepatocellular carcinoma(HCC) providing a reference for clinical diagnosis and treatment.Methods A total of 104 patients with HCC who underwent surgical treatment in the Department of Hepatobiliary Surgery of our hospital from January 2024 to April 2024 were selected as the study group, and 139 patients with benign biliary diseases during the same period were selected as the control group. Atomic absorption spectrometry was used to detect the levels of six trace elements (copper, zinc, calcium, magnesium, iron, and lead) in the serum of both groups, and liquid chromatography-tandem mass spectrometry was used to measure the concentrations of 21 amino acids.Results Compared with the control group, the serum copper level in the HCC group was significantly increased (P<0.05), while the levels of zinc and iron were significantly decreased (P<0.05). Amino acid profile analysis revealed that, compared with the control group, the concentrations of tyrosine, methionine, and phenylalanine in the HCC group were increased (P<0.05), while the concentrations of valine, leucine, isoleucine, glutamine, and arginine were decreased (P<0.05). Further analysis of the correlation between trace elements and amino acids with statistical differences between the groups showed that copper was negatively correlated with valine and leucine (P<0.05), while zinc and iron were positively correlated with valine, leucine, and isoleucine (P<0.01).Conclusions Imbalances in trace elements and amino acid metabolism changes are common in patients with HCC, and there may be an intrinsic connection between the two.

The accumulation and spread of prion-like proteins is a key feature of neurodegenerative diseases (NDs) such as Alzheimer's disease, Parkinson's disease, or Amyotrophic Lateral Sclerosis. In a process known as 'seeding', prion-like proteins such as amyloid beta, microtubule-associated protein tau, α-synuclein, silence superoxide dismutase 1, or transactive response DNA-binding protein 43 kDa, propagate their misfolded conformations by transforming their respective soluble monomers into fibrils. Cellular and molecular evidence of prion-like propagation in NDs, the clinical relevance of their 'seeding' capacities, and their levels of contribution towards disease progression have been intensively studied over recent years. This review unpacks the cyclic prion-like propagation in cells including factors of aggregate internalization, endo-lysosomal leaking, aggregate degradation, and secretion. Debates on the importance of the role of prion-like protein aggregates in NDs, whether causal or consequent, are also discussed. Applications lead to a greater understanding of ND pathogenesis and increased potential for therapeutic strategies.

Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

Nutritional support is one of the comprehensive treatments for the patients with novel coronavirus infection, especially for critically ill patients. Nutritional therapy needs to follow the standard process, which includes nutritional risk screening, assessment, intervention and monitoring. Nutrition intervention is recommended to follow the principle of "five-step" of nutritional therapy. Appropriated diet and evidence-based nutritional support should be given to improve the nutritional status and immunologic function of the patients, and to get best of overall clinical outcomes.

The pathogenesis of endometriosis is not well understood at the moment, and the lack of effective biomarkers often leads to delayed diagnosis of the disease. Lipidomics provides a new approach for the diagnosis and prediction of endometriosis. Sphingomyelin, phosphatidylcholine and phosphatidylserine in peripheral blood, endometrial fluid, peritoneal fluid and follicular fluid have good diagnostic value for endometriosis and disease classification; the lipid metabolites in the eutopic endometrium tissue are expected to be biomarkers of early endometriosis; and the lipid metabolites in peripheral blood are also of great value for predicting endometriosis-related infertility. The development of lipidomics technique will further advance the progress on the pathogenesis, prediction, diagnosis and treatment of endometriosis.

Objective To explore the effects of stress and self-efficacy on the quality of life in patients with gallstones and the effect relationship of self-efficacy in the quality of life and stress, and provide guidance for the health intervention of patients with gallstones. Methods Totally 362 patients with gallstones after operative that already returned to the community for 12 months were investigated, and their stress condition, self-efficacy and quality status of life were measured by the life events scale ( LES ) , self-efficacy scale and gastrointestinal quality of life index (GIQLI). The effect relationship of self-efficacy in the quality of life and stress was analyzed.Results The self-efficacy played partial mediating effect between stress and quality of life. When the intermediary variables-self-efficacy sense was participated in, the regression coefficient between stress and quality of life was significantly reduced (β was reduced from -0. 695 to -0. 548 ) . Self efficacy played regulating effect between stress and quality of life, which means that self efficacy sense × stress partial regression coefficient in the regression which regard the quality of life as the dependent variable can reach to a significant level (β=-0.086, P<0.05) , and introduced interaction terms after new interpretation (△R2 ) also can reach to a significant level (△R2 = 0. 017, P<0. 05 ) . Conclusions Self efficacy played the mediating effect and regulating effect in the relationship between stress and quality of life. Nursing staff can reduce the negative effects of stress events in patients′quality of life through the interventions in patients′self-efficacy.

Objective To inverstigate the effects of follow-up management based on social goals model on social relation quality in hepatocellular carcinoma patients after transcatheter arterial chemoebolization (TACE).Methods By convenience sampling method, a total of 113 patients after TACE were divided into the control group ( n=56) and the intervention group ( n=57) according to the treatment time. In the control group, routine follow-up based on case-management was adopted, while in the intervention group, the follow-up based on social goals model was adopted. The intervention effect in two groups were tested by social relation quality scale.Results After intervention, the total score of social relation quality, score of family adaptability and score of family commitment were (53.60±8.86),(20.34±3.28) and (18.07±2.96), and they were all significantly higher than the scores in the control group [(49.25±9.75),(18.52±3.55),(16.22±3.21)](P<0.05). Conclusions The follow-up management based on social goals model can effectively improve the level of family adaptability and family commitment. The intervention could be one of the effective ways to implement social relational quality fin patients after TACE.

Objective To investigated the value of intraoperative ultrasonography in guiding the surgical approach,improving the total resection rate of the tumor,and the survival time of patients who underwent resection of cerebral gliomas.Methods One hundred and ninteen patients with cerebral gliomas (pathologically confirmed) comprised the study groups.Patients who underwent intraoperative ultrasoundguided surgery were followed up for 6-60 months.In addition,randomly selected low and high grade cerebral glioma patients (all 30 cases of which were without intraoperative ultrasonography guidance) served as the control groups.Follow up included survival time,and the differences in survival time between the study groups and control groups were statistically analyzed.Results Complete follow-up data were obtained for 101 of 119 cases (84.9％) for a follow-up time of 6 60 months.Total removal of the lesion was achieved in 68 cases (67.3％) and subtotal removal in 33 cases (32.7 ％).Sixty-five cases had partial recurrence (64.4％) and 60 patients died due to tumor recurrence.Survival in patients with low grade gliomas (LGG) was significantly higher than that in patients with high grade gliomas (HGG).Patients with total tumor resection had a longer survival time than patients who had subtotal tumor resection.In the control LGG group,6-month survival was 96.7％,1-year survival was 73.3％,2-year survival was 53.3％,4-year survival was 36.7％ and 5-year survival was 26.7％.In the control HGG group,survival at 6 months,1 year,2 years,4 year and 5 years was 83.3％,36.7％,13.3％,3％,0 respectively.When comparing survival between the control groups and study groups,there was no significant difference at 6 months (P ＞0.05),but survival at 1 year,2 years,4 year and 5 years was different (P ＜0.05).Conclusions Intraoperative ultrasonography-guided resection of cerebral gliomas helps the surgeon to understand the relationship between the lesion and the surrounding structures,helps to protect normal brain tissue and increase the safety of surgery.It is of value in improving the total resection rate of tumors and the patient's survival time.
