Objective: To explore influence of coping style on sleep quality and blood pressure in community male population with high normal value blood pressure. Methods: The Pittsburgh sleep quality index (PSQI) and coping style questionnaire (CSQ) were used to assess 120 men with high normal blood pressure in community. With PSQI>7 scores as criterion for judging sleep quality disorders, the subjects were divided into sleep disorder group (n=51) and normal sleep group (n=69), and sleep disorder group received psychological intervention. Results: Sleep disorders existed in 42.5% male population with high normal blood pressure. Compared with normal sleep group, there was significant increase in PSQI [(6.43±2.59)scores vs. (8.33±3.14)scores] and diastolic blood pressure [(81.00±8.91) mmHg vs. (88.00±5.69) mmHg] and significant decrease in factor scores of “problem solving” [(0.76±0.21) scores vs. (0.61±0.18) scores] and “asking for help” [(0.52±0.26) scores vs. (0.41±0.11) scores] in sleep disorder group, P<0.05 all; Compared with before intervention there were significant increase in scores of “problem solving” [(0.61±0.18) scores vs. (0.71±0.12) scores]and “asking for help” [(0.41±0.11) scores vs. ( 0.51±0.13) scores]and significant decrease in PSQI score [(8.33±3.14) scores vs. (7.41±2.37) scores] and diastolic blood pressure [(88±5.69)mmHg vs. (80± 4.17)mmHg] after psychological intervention 12 weeks in sleep disorder group, P<0.05 all. Conclusion: Psychological intervention may improve sleep quality and reduce blood pressure in community male population with high normal value blood pressure.

Objective To investigate the auxiliary diagnostic value of combined detection serum lipoprotein-associated phospholipase A2 (LP-PLA2) and small and dense low-density lipoprotein (sd-LDL) in atherosclerosis.Methods The subjects were divided into experimental group and control group by random block design from May 2017 to January 2018,in the First Affiliated Yijishan Hospital of Anhui Wannan Medical College.The experimental group selected 125 AS patients with clinical diagnosis and confirmed by angiography,and 55 healthy subjects were chosen as the normal control group at the same time.Serum samples were collected within 24 hours after admission,and the level of LP-PLA2,sdLDL-C,low density lipoprotein cholesterol (LDL-C),triglyceride (TG),total cholesterol (TC) and high-sensitive C reactive protein (hs-CRP) were unified detection.The t test,single factor variance analysis and Mann-Whitney U and multivariate logistic regression analysis were used to analyze the data.Results LP-PLA2,sd-LDL,LDL,TC,TG and hs-CRP of the AS group were all higher than those of the healthy control group (Z=5.279,6.663,6.012,5.863,5.508 and 2.845,respectively,P<0.05).Logistic regression analysis showed that serum LP-PLA2,sd-LDL and hs-CRP level was an independent risk factor for predicting atherosclerosis (OR=1.008,P=0.003;OR=8.282,P=0.012;OR=1.158,P=0.009).The sensitivity of LP-PLA2,sd-LDL,LDL-C,TC,TG,hs-CRP to AS was detected separately (57.6%,73.6%,85.6%,83.2%,76.8%,80.0%),and the specificity was (89.1%,78.2%,67.3%,69.1%,74.5%,52.7%).The ROC curve showed that the diagnostic efficacy of LP-PLA2 and sd-LDL combined detection was 0.854,higher than sd-LDL,LDL-C,TC,TG,LP-PLA2 and hs-CRP (0.811,0.782,0.775,0.758,0.747 and 0.633,respectively).In addition,the levels of both increased with the aggravation of arteriosclerotic lesion(x2=7.954,P=0.019;x2=11.44,P=0.003).The levels of LP-PLA2 and sd-LDL in patients with AS were not significantly different between different lesions (x2=8.042,P=0.09;x2=5.952,P=0.203).There was no significant difference between serum LP-PLA2 and sd-LDL level and sex,age,smoking,hypertension and diabetes (Z1=0.398,0.719,0.619,0.098 and 1.338 respectively,Z2=0.942,0.027,0.894,0.375,0.783,respectively,both P1 and P2 were>0.05).Conclusions sd-LDL combined with LP-PLA2 has high sensitivity and specificity in the prediction of AS,which makes up for the deficiency of individual detection;sd-LDL and LP-PLA2 serum level has nothing to do with the lesion and has a positive correlation with the degree of lesions.It is not easily affected by other risk factors and can be used as a risk factor for predicting the occurrence of AS.
4.Research on the role of P2X receptor channel protein in the progression of solid tumors
Journal of Xi'an Jiaotong University(Medical Sciences) 2024;45(4):686-694
Adenosine triphosphate (ATP) is the most common energy supplier in living organisms and also an important signaling molecule. The expression level of ATP is significantly upregulated in the tumor microenvironment. The purinergic receptor ion channel P2X is widely distributed in various tissues. ATP can specifically activate the P2X receptor to induce the opening of gated ion channels in the microenvironment, thereby affecting the downstream signal transduction in regulating the physiological activities. Notably, abnormal purinergic signal plays an important role in tumor progression. This review focuses on the expression, structure, and function of the P2X receptor protein family. It also elucidates the mechanisms by which the P2X receptor family participates in the progression of various solid tumors, as well as research on targeted P2X family for tumor therapy. These studies will enrich the basic research theory related to purinergic signaling and provide the new targets and strategies for clinical therapy of solid tumors by targeting P2X family.

Objective:To investigate the correlation of intratumoral fibrosis with the prognosis of clear cell renal cell carcinoma (ccRCC).Methods:The correlation of the transcriptional expression of the primary collagen with the prognosis in ccRCC was evaluated using the Cancer Genome Atlas (TCGA) database, including 530 ccRCC patients with complete information. Of them, 344 cases were male, 186 cases were female. The age of 264 cases was ≤ 60 years, and the age of 266 cases was > 60 years. The pathology grade of 241 patients was G 1-2 grade, and the pathology of 281 cases were G 3-4 grade, 8 cases were undetermined grade. There were 322 cases with AJCC stage Ⅰ-Ⅱ and 205 cases with AJCC stage Ⅲ-Ⅳ, and 3 cases with undetermined stage. There were 420 cases in M 0 and 78 cases in M 1, and 32 cases without distant metastases information. Furthermore, the paraffin sections of 158 non-cystic ccRCC patients confirmed by pathology from November 2005 to November 2017 were further used to evaluate the level of collagen of ccRCC and the status of the pseudocapsule by the Masson staining, Sirius red staining and multicolor immunofluorescence staining of collagen Ⅰ and collagen Ⅲ. Of them, 112 cases were male, 46 cases were female. There were 100 cases with age ≤ 60 years, and 58 cases with age > 60 years. The pathology grade of 111 cases were G 1-2, and the pathology grade of 47 cases were G 3-4. There were 144 cases with AJCC stage Ⅰ-Ⅱ, 14 cases with AJCC stage Ⅲ-Ⅳ. Kaplan-Meier survival curve were used to analyze the relationship between tumor collagen parameters and the overall survival prognosis of patients with ccRCC. Results:The transcriptome results of the TCGA database indicated that the expression level of COL1A1 in ccRCC tissues was significantly higher than that in adjacent normal tissues ( P<0.001). The high expression of collagen suggested a worse overall survival prognosis ( HR=1.165, P=0.002). In addition, the high ratio of COL1A1/COL3A1 indicated a worse overall survival prognosis ( HR=1.901, P<0.001) compared with the low ratio. We further confirmed that the abundance of collagen in tumor was significantly increased compared with the normal adjacent tissues by the Masson staining [41.0 (14.0-75.0) vs.15.0 (3.0-57.0), P<0.001] and the Sirius red staining [42.5 (10.0-90.0) vs.10.0 (2.5-60.0), P<0.001] on 30 ccRCC tissues and adjacent normal tissues. Based on the Masson staining, we found that high collagen abundance in tumor tissue was associated with more G 3-4 grade of tumor compared with low collagen abundance (38.5% vs.21.3%, OR=2.316, 95% CI 1.146-4.681, P=0.023). Kaplan-Meier survival curve showed that higher collagen abundance was associated with a worse overall survival prognosis in ccRCC ( HR=2.630, P=0.007). However, incomplete fibrous pseudocapsule was associated with a worse overall survival prognosis ( HR=11.140, P<0.001). Conclusions:In ccRCC, intratumoral collagen fiber level was overexpressed. High intratumoral collagen level and incomplete fibrous pseudocapsule may indicate a poor overall survival prognosis.

Objective:To investigate the clinical and pathological characteristics and prognosis of upper tract urothelial carcinoma (UTUC) with concurrent other histological variants.Methods:The clinical data of 566 UTUC patients admitted to Peking University People's Hospital from January 2007 to April 2021 were retrospectively analyzed. Among them, 289 were males and 277 were females, with an average age of (67.3±10.0)years old. Among the patients, 97 had a history of smoking, 29 had undergone kidney transplantation, 120 had diabetes, 76 had coronary heart disease, 146 had hyperlipidemia, 271 had hypertension, and 50 had a history of chronic kidney disease. Among the UTUC cases, 366 had concurrent hydronephrosis, 55 had concurrent bladder cancer, and 43 had a history of previous bladder cancer. The distribution included 210 cases of renal pelvis carcinoma, 5 cases of carcinoma at the renal pelvis-ureter junction, 226 cases of ureteral carcinoma, and 125 cases of multifocal tumors. Patients were classified into the pure UTUC group and the UTUC with concurrent other histological variants group based on postoperative pathology, and their clinical and pathological features were compared. Logistic regression analysis was used to explore risk factors for the occurrence of histological variations in UTUC. The log-rank test was employed to compare the overall survival (OS) and cancer-specific survival (CSS) between the two groups, while Cox regression analysis was performed to investigate prognostic factors.Results:Among the 566 cases, 511 were pure UTUC and 55 were UTUC with concurrent other histological variants. Among the latter, 30 cases had squamous differentiation, 6 had glandular differentiation, 5 had mucinous differentiation, 5 had sarcomatoid carcinoma, 2 had micropapillary carcinoma, 2 had neuroendocrine carcinoma, 1 had giant cell carcinoma, and 4 had other mixed histological variations. The proportion of patients with a history of kidney transplantation was higher in the UTUC with concurrent histological variants group than that in the pure UTUC group [14.5% (8/55) vs. 4.1% (21/511)], with statistically significant difference ( P=0.003). In the UTUC with concurrent histological variants group, the proportion of postoperative high-grade tumors [98.2% (54/55) vs. 80.2% (410/511)], muscle-invasive tumors [89.1% (49/55) vs. 68.1% (348/511)], lymph node metastasis tumors [10.9% (6/55) vs. 2.3% (12/511)], and maximum tumor diameter [(3.60±2.64) cm vs. (2.96±1.98) cm] were higher than those in the pure UTUC group ( P<0.05). Multivariate logistic regression analysis showed that a history of kidney transplantation ( OR=4.991, 95% CI 1.749-13.615, P=0.002) was an independent predictive factor for the occurrence of histological variants. Follow-up was conducted for 1 to 174 months, with a median follow-up time of 32.8 months. UTUC with concurrent histological variants was significantly associated with worse OS and CSS ( P<0.05). Multivariate Cox regression analysis indicated that histological variants were an independent risk factor for OS ( HR=1.860, 95% CI 1.228-2.816, P=0.003) and CSS ( HR=2.146, 95% CI 1.349-3.412, P=0.001). Conclusions:UTUC with concurrent other histological variants exhibited higher postoperative tumor grade and stage compared to pure UTUC, and UTUC with concurrent other histological variants was an independent risk factor for worse prognosis.

【Objective】 To investigate the effects of emotions (subjective well-being, depressed effect, worry, and guilt) on cancer (colorectal cancer, hepatic cancer, thyroid cancer, lung cancer, and breast cancer). 【Methods】 Two-sample bi-directional Mendelian randomization (MR) method was adopted. All data were based on summary data from genome-wide association studies (GWAS). Inverse variance weighting (IVW) was used to generate the main results, and weighted median (WM) and MR-Egger methods were employed to calculate supplementary results. The outcome measure was odds ratio (OR), and sensitivity analysis was conducted. 【Results】 For depressed effect, a significant association with lung cancer (OR=1.005, 95% CI: 1.001-1.009, P=0.015) was found. For worry, a significant association with breast cancer (OR=1.199, 95% CI: 1.011-1.423, P=0.038) was observed. For guilt, a significant association with thyroid cancer (OR=2.083, 95% CI: 1.080-4.017, P=0.029) was identified. After removing all potentially pleiotropic SNPs detected by MR PRESSO, the association between worry and breast cancer showed no statistical difference (P=0.064), while the association between worry and colorectal cancer remained significant (OR=0.739, 95% CI: 0.571-0.956, P=0.021). No causal relationship was found between cancer and emotions. 【Conclusion】 There is a causal relationship between depression and increased lung cancer incidence, guilt and increased thyroid cancer incidence, as well as anxiety and decreased colorectal cancer incidence.
