Objective:To analyze the correlation between mental health status and metabolic syndrome (MetS) in health checkup people.Methods:It was a cross-sectional study, 2 920 participants who received health checkup in the Health Examination Center of Peking University Third Hospital from January 2019 to December 2023 were selected using cluster sampling method. Their general information, physical examination, biochemical indicators, body composition, and self-evaluation scores on the Symptom Checklist-90 (SCL-90) were collected. According to the inclusion and exclusion criteria, a total of 2 813 study subjects were included, and divided into the MetS group and the non-MetS group based on whether they had MetS. The differences in general demographic information, body composition, blood biochemistry, and SCL-90 scores between the two groups were compared. Binary Logistic regression analysis was used to explore the correlation between mental health status and MetS.Results:Of the 2 813 subjects included, 1 576 were males (56.0%) and 1 237 were females (44.0%), with an average age of (41.7±11.0) years, the MetS group had 586 cases (20.8%) and the non-MetS group had 2 227 cases (79.2%). The MetS group had higher levels of age, body mass index, waist circumference, systolic blood pressure, diastolic blood pressure, total cholesterol, triglycerides, low density lipoprotein cholesterol (LDL-C), fasting blood glucose, glycosylated hemoglobin (HbA 1c), free thyroxine(FT4), total triiodothyronine (TT3), free triiodothyronine (FT3), waist-to-hip ratio, visceral fat area, body fat percentage, uric acid/creatinine, homocysteine (Hcy), aspartate aminotransferases (AST), and alanine transaminase (ALT) levels, as well as higher scores for somatization, hostility, paranoia, and other factor compared to the non-MetS group (all P<0.05), while high density lipoprotein cholesterol (HDL-C) and estimated glomerular filtration rate (eGFR) levels were lower than those in the non-MetS group (all P<0.05). The proportion of male, and the positive rates of SCL-90, somatization, interpersonal sensitivity, hostility, paranoia and other factor in the MetS group were higher than those in the non-MetS group (all P<0.05). Multifactorial analysis showed that individuals with a positive SCL-90 assessment had a 1.34 times higher risk of MetS than those with a negative assessment ( OR=1.34, 95% CI: 1.06-1.68; P=0.014). Among them, individuals with positive somatization ( OR=2.02, 95% CI: 1.25-3.28; P=0.004) and hostility ( OR=1.61, 95% CI: 1.02-2.56; P=0.042) had increased risk of MetS. Conclusion:Poor mental health status increases the risk of MetS.

Objective:To evaluate the value of CEA, CYFRA21-1 and CA125 tests in opportunistic screening of non-small cell lung cancer (NSCLC) based on meta-analysis.Methods:The original research literatures on the diagnostic value of CEA, CYFRA21-1 and CA125 in Chinese NSCLC patients were searched from databases of PubMed, Embase, The Cochrane Library, CNKI, VIP, Database and Wanfang database from establishment to June 2023. The literature screening, data extraction and quality evaluation were carried out independently by two researchers. The quality evaluation tool of diagnostic accuracy studies was used to evaluate the quality of the literature. A summary receiver operating characteristic (SROC) curve was used to assess the overall effectiveness of the tests. The outcome stability and publication bias were detected by using sensitivity analysis and Deeks′ test.Results:A total of 23 studies met the inclusion and exclusion criteria were included. The results of meta-analysis showed that the overall sensitivity of CEA, CYFRA21-1 and CA125 alone in the diagnosis of NSCLC was relatively low, it was 0.49(95% CI: 0.43-0.55), 0.56(95% CI: 0.49-0.63) and 0.41(95% CI: 0.33-0.49), respectively. The overall sensitivity of the combined detection of the three markers for the diagnosis of NSCLC increased to 0.83(95% CI: 0.69-0.91), but the overall specificity decreased to 0.76(95% CI: 0.69-0.83). Conclusions:The single detection of CEA, CYFRA21-1 and CA125 is not recommended for screening NSCLC in population receiving physical examination. Although the sensitivity of the combined detection of CEA, CYFRA21-1 and CA125 for screening NSCLC is improved, but the specificity is decreased, the misdiagnosis rate is increased, so the screening effect is limited.

Objective To investigate the therapeutic effect of segmental decompression combined with corrective short-segment fusion surgery for the treatment of degenerative lumbar scoliosis.Methods In total,124 patients with degenerative lumbar scoliosis were selected and divided into short-and long-segment fusion groups using the random number table method,with 62 patients in each group.Posterior short-segment decompression,fixation,and fusion were performed in the short-segment fusion group;the fusion segment was the adjacent lumbar vertebra.Posterior long-segment decompression,fixation,and fusion were performed in the long-segment fusion group;the fusion segments included multiple adjacent lumbar vertebrae.At the 6th month after surgery,the coronal Cobb angle of lumbar convexity,sagittal Cobb angle of lumbar lordosis,intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,spinal canal diameter,Japanese Orthopedic Association(JOA)score,Oswestry Disability Index(ODI),degree of pain in the lower back and lower limbs,and postoperative complications were compared between the groups.Results The Cobb angle of the coronal lumbar scoliosis in the short-and long-segment fusion groups was significantly higher than that before surgery(P<0.05).At the 6th month after surgery,the intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,and spinal canal diameter in both groups increased,and those in the short-segment fusion group were higher than those in the long-segment fusion group(P<0.05);at the 6th month after the operation,the JOA scores of the short-segment and long-segment fusion groups were higher than those before surgery,and the JOA score of the short-segment fusion group was higher than that of the long-segment fusion group(P<0.05).The ODI score was lower than that before surgery in the short-and long-segment fusion groups,and the ODI score in the short-segment fusion group was lower than that in the long-segment fusion group(P<0.05).At the 6th month after surgery,the pain scores of the lower back and lower limbs in the short-and long-segment fusion groups were significantly higher than those before surgery(P<0.05).There were two cases of dural tears during decompression caused by lamina dura adhesion in the long-segment fusion group,and no serious complications were observed in the short-segment fusion group.Conclusions Both short-and long-segment decompression fixation fusion using a posterior approach can achieve good therapeutic effects for treating degenerative lumbar scoliosis.However,compared to the long-segment fusion group,the short-segment fusion group undergoing short-segment decompression fixation fusion through a posterior approach had a shorter surgical period,lower intraoperative blood loss,better recovery of lumbar function,and a lower risk of postoperative complications.

Lipids have been found to modulate tumor biology, including proliferation, survival, and metastasis. With the new understanding of tumor immune escape that has developed in recent years, the influence of lipids on the cancer-immunity cycle has also been gradually discovered. First, regarding antigen presentation, cholesterol prevents tumor antigens from being identified by antigen presenting cells. Fatty acids reduce the expression of major histocompatibility complex class I and costimulatory factors in dendritic cells, impairing antigen presentation to T cells. Prostaglandin E2 (PGE2) reduce the accumulation of tumor-infiltrating dendritic cells. Regarding T-cell priming and activation, cholesterol destroys the structure of the T-cell receptor and reduces immunodetection. In contrast, cholesterol also promotes T-cell receptor clustering and relative signal transduction. PGE2 represses T-cell proliferation. Finally, regarding T-cell killing of cancer cells, PGE2 and cholesterol weaken granule-dependent cytotoxicity. Moreover, fatty acids, cholesterol, and PGE2 can improve the activity of immunosuppressive cells, increase the expression of immune checkpoints and promote the secretion of immunosuppressive cytokines. Given the regulatory role of lipids in the cancer-immunity cycle, drugs that modulate fatty acids, cholesterol and PGE2 have been envisioned as effective way in restoring antitumor immunity and synergizing with immunotherapy. These strategies have been studied in both preclinical and clinical studies.

Mevalonate metabolism plays an important role in regulating tumor growth and progression; however, its role in immune evasion and immune checkpoint modulation remains unclear. Here, we found that non-small cell lung cancer (NSCLC) patients with higher plasma mevalonate response better to anti-PD-(L)1 therapy, as indicated by prolonged progression-free survival and overall survival. Plasma mevalonate levels were positively correlated with programmed death ligand-1 (PD-L1) expression in tumor tissues. In NSCLC cell lines and patient-derived cells, supplementation of mevalonate significantly up-regulated the expression of PD-L1, whereas deprivation of mevalonate reduced PD-L1 expression. Mevalonate increased CD274 mRNA level but did not affect CD274 transcription. Further, we confirmed that mevalonate improved CD274 mRNA stability. Mevalonate promoted the affinity of the AU-rich element-binding protein HuR to the 3'-UTR regions of CD274 mRNA and thereby stabilized CD274 mRNA. By in vivo study, we further confirmed that mevalonate addition enhanced the anti-tumor effect of anti-PD-L1, increased the infiltration of CD8⁺ T cells, and improved cytotoxic function of T cells. Collectively, our findings discovered plasma mevalonate levels positively correlated with the therapeutic efficacy of anti-PD-(L)1 antibody, and provided the evidence that mevalonate supplementation could be an immunosensitizer in NSCLC.

Objective:To analyze the core elements′ index design of physical examination reports and pilot data.Methods:We searched and analyzed the core element indexes of the physical examination report in databases such as CNKI and Wanfang through the literature analysis method, forming the initial core element indicator set. Special working meetings were organized to discuss revisions and improvements. The core elements′ index set was formed using a mixed research method combined with the quantitative analysis results of pilot data and expert opinions. Six hundred and thirteen cases from five hospitals were included in this study, including Anzhen Hospital, Peking University Third Hospital, Beijing Physical Examination Center, Beijing Tongren Hospital, China-Japan friendship hospital.Results:The subjects were (49.5±17.6) years old, including 302 males (49.3%) and 311 females (50.7%). The physical examination conclusion indicates that the number of health problems is between five and eight, with no significant difference between men and women. The health history data analysis of different sexes showed that hypertension in men was significantly higher than in women (17.9% vs. 10.6%, P=0.010). The lifestyle and eating habits survey showed that men had significantly higher incidences of smoking and drinking than women (24.8% vs. 2.2%, P?0.001; 9.9% vs. 1.3%, P?0.001). The exercise habits and sleep survey showed that the proportion of men who did not exercise was lower than that of women (13.2% vs. 22.8%, P=0.022). There was no statistically significant difference in sleep duration between the sexes. Conclusions:The core elements of health examination reports can standardize the collection of physical examination data and improve its sharing and application. This can allow the reports to better assist the decisions based upon physical examination report data.

Objective:To analyze the correlation between the body composition and cardiorespiratory fitness (CRF) decline in physical examination population of different genders.Methods:Clinical data of the cardiopulmonary exercise testing (CPET) and body composition analysis of 439 people who received physical examination in the Medical Examination Center of Peking University Third Hospital from May 2021 to September 2021 were retrospectively analyzed. The general data, physical examination, biochemical parameters, body composition and CPET results were collected. The subjects were divided into normal group and decline group according to the percentage of peak oxygen uptake (VO 2peak) levels ≥ 85% or<85%. Multivariate logistic regression was applied to investigate the influencing factors of CRF decline in subjects of different genders. Results:Among men, total cholesterol and triglyceride in the decline group were significantly higher than those in the normal group [(5.097±0.890) vs (4.865±0.856) mmol/L, (1.778±1.200) vs (1.485±0.709) mmol/L], and the blood homocysteine (Hcy) and skeletal muscle index were significantly lower than those in the normal group [13.00 (11.30, 15.90) vs 13.80 (12.05, 17.10) μmol/L, (7.89±0.65) vs (8.08±0.64) kg/m 2] (all P<0.05). Among women, skeletal muscle index in the decline group was significantly lower than that in the normal group [(6.21±0.52) vs (6.53±0.56)kg/m 2], and percent body fat was significantly higher than that in the normal group [(32.83±4.92)% vs (31.21±4.55)%] (all P<0.05). The elevation of triglyceride level ( OR=1.487, 95% CI: 1.042-2.121) and visceral fat area ( OR=1.032, 95% CI: 1.014-1.051) were positively correlated with the decline of CRF in man, the decrease of skeletal muscle index ( OR=0.215, 95% CI: 0.106-0.435) and the increase of percent body fat ( OR=1.149, 95% CI: 1.060-1.245) were positively correlated with the decrease of CRF in women (all P<0.05). Conclusions:There is a correlation between body composition and CRF decline in physical examination population of different genders. Men should control visceral fat more effectively, and women should pay attention to increase muscle mass while reducing body fat, in order to improve CRF.

Objective:To analyze the clinical, imaging and pathological characteristics of pleomorphic xanthoastrocytoma (PXA), and to explore the effective treatment of PXA.Methods:A total of 25 patients with PXA admitted to our hospital from July 1, 2012 to December 1, 2019 were chosen in our study. Their clinical manifestations, imageology features, pathology features, treatments, and prognoses were retrospectively analyzed.Results:Headache ( n=12) and epilepsy ( n=8) were the most common first symptoms in 25 patients. The tumors in 8 patients were located in the parietal lobe, 6 were in the temporal lobe, and 6 were in the frontal lobe. Among the pathological results, the average positive rate of cell proliferation antigen Ki-67 and P53 in patients with WHO grading II was 6.4% and 21.2%, respectively; the average positive rate of Ki-67 and P53 in patients with WHO grading III was 22.2% and 48.3%, respectively. Synaptophysin protein was confirmed in 12 of the 15 patients. Twenty patients were followed up for 31 months after surgery; 19 survived; 9 had no tumor recurrence or residue, including 8 with WHO grading II and one with WHO grading III. Conclusion:Pathological result play an important role in PXA diagnosis; the prognosis of patients with WHO grading II is obviously better than that of patients with WHO grading III.
