Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Background The decline of physical activity in the elderly due to aging may increase the risk of sarcopenia. Currently, there is a lack of evidence from large natural populations on the relationship between PA and sarcopenia. Objective To explore the relationship between PA and sarcopenia in the elderly aged 60 years and above in 10 provinces (autonomous regions) of China. Methods Data were retrieved from the 2022—2023 round of the China Development and Nutrition Health Impact Cohort. Personal basic information and PA data were collected by questionnaire survey. Skeletal muscle mass was measured by bio-electrical impedance analysis, muscle strength was measured using a grip dynamometer, and physical performance was reflected by 6-meter walk speed. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used to diagnose sarcopenia. Light physical activity (LPA) duration, moderate-to-vigorous physical activity (MVPA) duration, and total physical activity volume were calculated. A total of 3326 residents aged ≥60 years with complete data were selected as the survey participants. Multiple logistic regression models and restricted cubic splines (RCS) were used to assess the association between PA duration/volume and sarcopenia. Results In 10 provinces (autonomous regions) of China, the prevalence of sarcopenia in the elderly aged 60 years and above was 5.5% (95%CI: 4.7%, 6.2%). The logistic regression analysis showed that compared with the elderly reporting 0-7.0 h·week⁻¹ in LPA duration, the risk of sarcopenia in the elderly with LPA duration of >14.0-21.0 h·week⁻¹ was reduced by 51% (OR=0.49, 95%CI: 0.26, 0.96). Compared with the elderly with total physical activity ≥15.0 metabolic equivalent of task (MET)-h·week⁻¹, those with <7.5 MET-h·week⁻¹ had a 2.24-fold increased risk of sarcopenia (OR=2.24, 95%CI: 1.17, 4.29). The RCS results found that LPA duration and total physical activity volume each showed a nonlinear dose-response relationship with the risk of sarcopenia (P_overall<0.05, P_non-linear<0.05). Compared with the elderly with an LPA duration of 0 h· week⁻¹, the risk of sarcopenia in the elderly with an LPA duration of 12.6 h· week⁻¹ was the lowest (OR=0.42, 95%CI: 0.21, 0.83). Compared with the elderly with a total physical activity volume of 15.0 MET-h· week⁻¹, the elderly with a total physical activity volume of 46.0 MET-h· week⁻¹ had the lowest risk of sarcopenia (OR=0.57, 95%CI: 0.38, 0.84). There was no statistically significant association between weekly MVPA duration and the risk of sarcopenia (P>0.05). Conclusion Increasing weekly LPA duration and total physical activity volume would help to reduce the risk of sarcopenia.

Objective: To compare the effectiveness of qualitative and quantitative fecal immunochemical tests (FIT) in identifying colorectal cancer, so as to provide insights into perfecting screening strategies for colorectal cancer. Methods: Participants in the Colorectal Cancer Screening Program for Key Populations in Zhejiang Province from May 2020 to December 2021 were recruited, and their demographic information, lifestyle and disease history were collected through a questionnaire survey. Qualitative or quantitative FIT along with a questionnaire-based risk assessment were employed as the initial screening tests. Individuals who were positive in any FIT or had high-risk assessment results were required to attend a subsequent colonoscopy examination. The positive rate, detection rate of colorectal cancer, positive predictive value and number of colonoscopies required were compared between qualitative and quantitative FITs, and stratified analyses by gender and age were conducted. Results: Totally 4 099 769 participants were included. The qualitative FIT group included 3 574 917 individuals, yielding a positive rate of 11.35%, a detection rate of 1.19%, a positive predictive value of 0.48% and 83.84 colonoscopies required to detect one cancer case. The quantitative FIT group involved 524 852 individuals, yielding a positive rate of 6.70%, a detection rate of 2.31%, a positive predictive value of 1.01% and 43.23 colonoscopies required to detect one cancer case. The quantitative FIT group showed significantly higher detection rate of colorectal cancer, higher positive predictive value and less number of colonoscopies required compared to the qualitative FIT group (all P<0.05). The same results were obtained after stratification by gender and age. Conclusion Compared to qualitative FIT, quantitative FIT improves the detection of colorectal cancer and reduces the workload of colonoscopy examinations, making it more suitable for colorectal cancer screening in large-scale populations.

Non-small cell lung cancer (NSCLC) is one of the most common types of cancer in the world and is an important cause for cancer death. Although the application of immunotherapy in recent years has greatly improved the prognosis of NSCLC, there are still huge challenges in the treatment of NSCLC. The immune microenvironment plays an important role in the process of NSCLC development, infiltration and metastasis, and they can interact and influence each other, forming a vicious circle. Notably, single-cell RNA sequencing enables high-resolution analysis of individual cells and is of great value in revealing cell types, cell evolution trajectories, molecular mechanisms of cell differentiation, and intercellular regulation within the immune microenvironment. Single-cell RNA sequencing is expected to uncover more promising immunotherapies. This article reviews the important researches and latest achievements of single-cell RNA sequencing in the immune microenvironment of NSCLC, and aims to explore the significance of applying single-cell RNA sequencing to analyze the immune microenvironment of NSCLC.

【Objective】 To explore the causal association between the onset of gastroesophageal reflux disease (GERD) and migraine and to provide genetic evidence, a two-sample bidirectional Mendelian randomization (MR) method was used in this study. 【Methods】 Single nucleotide polymorphism (SNP) information for both samples was obtained from publicly available genome-wide association study (GWAS) databases, in which the appropriate SNPs were selected as instrumental variables, and then bidirectional MR analysis used five MR analysis methods including inverse variance weighting (IVW), MR-Egger regression, weighted median, weighted mode and simple mode methods, followed by sensitivity analysis. 【Results】 IVW showed positive results of forward MR analysis with GERD as exposure [OR=1.398 7, 95%CI (1.181 7-1.655 6), P=9.59×10^-5] , while no positive significance of reverse MR analysis results with migraine as exposure (P>0.05). The same results were obtained in methods other than MR-Egger method. Meanwhile, none of the instrumental variables were found to be horizontally polytomous (P=0.92, P=0.64), and the results were robust after the leave-one-out method to exclude single SNPs. 【Conclusion】 There may be a unidirectional causal association between GERD and migraine, and GERD is a risk factor for migraine development.

Objective To compare the short-term clinical effects of Da Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of posterior mediastinal tumors, and to explore the advantages of RATS posterior mediastinal tumor resection. Methods The clinical data of patients who underwent posterior mediastinal tumors resection through the lateral chest approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between January 2019 to January 2023 were retrospectively analyzed. According to the different surgical methods, the patients were divided into a RATS group and a VATS group. The clinical data were compared between the two groups. Results A total of 85 patients were included in this study. There were 39 patients in the RATS group, including 25 females and 14 males, with an average age of 47.6±13.0 years, and 46 patients in the VATS group, including 14 males and 32 females, with an average age of 45.3±14.7 years. All patients completed the operation successfully. The hospitalization cost in the RATS group was significantly higher than that in the VATS group (P<0.001), and the white blood cell count and neutrophilic granulocyte percentage on the first day after operation in the RATS group were lower than those in the VATS group, and the differences were statistically significant (P<0.05). The operative time, intraoperative bleeding, postoperative hospital stay, white blood cell count and neutrophil percentage on the third postoperative day, visual analogue scale score on the first and third postoperative days, duration of analgesic pump use, postoperative 12 h oxygen saturation (no oxygen inhalation), postoperative down bed time, total thoracic drainage volume, duration of drainage tube retention, and postoperative complication rates were not statistically different between the two groups (P>0.05). There was no perioperative death, conversion to thoracotomy or serious perioperative complications in both groups. Conclusion RATS resection of posterior mediastinal tumor via lateral thoracic approach is safe and feasible, and its short-term effect is similar to that of VATS via lateral thoracic single-hole approach. It is worth further comparative study to explore its benefit and cost performance.

Objective:To explore the effect of humanistic care combined with Morita therapy on anxiety state of hemodialysis patients.Methods:A self-controlled study was conducted on 54 patients with end-stage renal disease and anxiety who received maintenance hemodialysis in China-Japan Friendship Hospital from August 2020 to August 2022. All patients were treated with humanistic care nursing and Morita therapy for one month. The Self Rating Anxiety Scale (SAS) scores of the patients before and after the intervention were compaired. The comparison of quantitative data was conducted by paired t-test, and the comparison of qualitative data was conducted by χ2 test. The correlation between different factors and anxiety was analyzed by Spearman correlation analysis. Results:Among the 54 patients, there were 26 males and 28 females, aged (61.8±16.3) years (ranging from 29 to 88 years). The SAS score after the intervention (44.0±11.1) was lower than that before the intervention (51.9±8.5) ( t=5.395, P<0.001). The anxiety of patients was related to their age ( r=0.305), employment status ( r=0.270) and marital status ( r=0.397) (all P<0.05). The satisfaction of patients with care measures and nursing before and after the intervention was 45.6% and 87.7%, respectively ( χ2=5.720, P<0.05). Conclusion:After receiving combined humanistic care nursing and Morita therapy, patients in a state of anxiety could experience significant psychological improvement, which is conducive to the successful completion of hemodialysis treatment and enhances the quality of life for patients.

Objective:To investigate the distribution of pathological types of unilateral primary aldosteronism, and to explore the clinical characteristics and prognosis of patients with different pathological types.Methods:A total of 241 patients with unilateral primary aldosteronism who underwent adrenal surgery were included in this study. The clinical data and postoperative follow-up data were collected, and the postoperative tissue sections were stained with HE and aldosterone synthase. According to the staining results, pathological types of 241 patients were classified, and the clinical characteristics and surgical prognosis of patients with unilateral primary aldosteronism were compared.Results:According to the international histopathology consensus for unilateral primary aldosteronism, among 241 patients with unilateral primary aldosteronism, 223 were classical(92.5%), 17 were non-classical(7.1%), and 1 was aldosterone producing carcinoma(0.4%). Among classical cases, 189 were aldosterone producing adenoma and 34 were aldosterone producing nodule. In the non-classical cases, 8 cases were multiple aldosterone producing nodule and 9 cases were multiple aldosterone producing nodule. Compared with the classical group, the non-classical group had a longer duration of hypertension(9.0 vs 5.0 years, P=0.062) and a lower baseline plasma aldosterone concentration(273 vs 305 pg/mL, P=0.147), but the difference was not significant. There was no significant difference between the two groups in the proportion of patients who achieved a complete biochemical response after surgery(98% vs 92.3%, P=0.281), but the proportion of patients who achieved a complete clinical response was significantly lower in the non-classical group(23.1% vs 52.9%, P=0.046). Conclusion:The pathological types of unilateral primary aldosteronism are predominantly classical, with aldosterone-producing adenoma being the most common. There were no significant differences in the clinical characteristics and postoperative biochemical remission rates between classical and non-classical patients, but the clinical prognosis of the latter was inferior to the former.

Objective:To evaluate postoperative biochemical and clinical remission rates in patients with unilateral primary aldosteronism and analyze related influencing factors.Methods:A total of 406 patients of primary aldosteronism with confirmed subtyping, who underwent adrenalectomy and completed follow-up in the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to March 2022 were retrospectively enrolled. Clinical and biochemical data were recorded. Postoperative clinical and biochemical outcomes were assessed according to Primary Aldosteronism Surgery Outcome(PASO) consensus.Results:Complete biochemical success was achieved in 391(96.31%) of 406 primary aldosteronism patients, while partial and absent biochemical success in only 4(0.99%) and 11(2.71%) primary aldosteronism patients; Complete clinical success was seen in 217(53.45%) patients, and partial clinical success in 189(46.55%) patients. Compared to the partial clinical success group, the complete clinical success group was younger, had a greater proportion of women, a smaller body mass index, a shorter duration of hypertension, a smaller daily defined dose value for antihypertensive medication, a higher estimated glomerular filtration rate(eGFR), and a lower proportion of family history of hypertension and diabetes mellitus. Multifactorial logistic regression analysis further showed that gender( OR=2.49, 95% CI 1.42-4.35, P=0.001), body mass index( OR=1.16, 95% CI 1.05-1.28, P=0.003), antihypertensive drug daily defined dose( OR=1.83, 95% CI 1.37-2.44, P<0.001), family history of hypertension( OR=2.16, 95% CI 1.22-3.83, P=0.008), history of diabetes( OR=2.47, 95% CI 1.15-5.29, P=0.021), and eGFR( OR=0.98, 95% CI 0.97-0.99, P=0.001) were independent factors influencing clinical prognosis of primary aldosteronism. Conclusion:The postoperative complete biochemical success is higher in patients with unilateral primary aldosteronism, but only about half of all patients achieve complete clinical success.

Objective:To investigate the appropriate cut-off for diagnosis of primary aldosteronism (PA) by seated saline suppression test (SSST) based on liquid chromatography with tandem mass spectrometry (LC-MS/MS).Methods:In this cross-sectional study, patients who underwent SSST for suspected PA in the First Affiliated Hospital of Chongqing Medical University from January 2018 to March 2022 were evaluated. Briefly, 300 patients with PA and 119 with essential hypertension (EH) were included. Plasma aldosterone concentration (PAC) after SSST was determined by LC-MS/MS. Primary aldosteronism confirmatory testing (PACT) score was used as the reference standard for diagnosis of PA, and receiver operating characteristic (ROC) curve was used to explore the cut-off value.Results:The average age of the PA group was (50.8±10.5) years, and males accounted for 53.00% ( n=159); the average age of the EH group was (49.4±11.2) years, and males accounted for 26.89% ( n=32). The area under the ROC curve of PAC post-SSST was 0.819 (95% CI 0.775-0.862). When 40 pg/ml (110.8 pmol/L) was selected as the appropriate cut-off for diagnosis of PA, the sensitivity was 83.67% (95% CI 78.88%-87.56%) and specificity was 60.50% (95% CI 51.10%-69.21%). Thus, 95.09% (155/163) of patients with unilateral PA could be identified. Conclusion:PAC after SSST determined by LC-MS/MS has high efficacy for diagnosis of PA, and 40 pg/ml is recommended as the appropriate cut-off value.
