Objective This study used The Cancer Genome Atlas (TCGA) database to investigate the methylation levels of PCDHGB7 in lung adenocarcinoma tissues and analyze its association with clinical pathological features of lung adenocarcinoma, and its prognostic predictive value. Methods Methylation data of PCDHGB7 from 473 lung adenocarcinoma tissues and 32 normal tissues in the TCGA database were derived and analyzed to assess between-group variance and determine the correlation of methylation levels with clinical pathological features and overall survival. Results PCDHGB7 exhibited significantly higher methylation levels in lung adenocarcinoma tissues than in normal tissues (P<0.001), demonstrating a strong discriminative ability for lung adenocarcinoma (AUC=0.926, P<0.001). The methylation level was strongly associated with gender (P=0.047) and T stage (P=0.013). The critical prognostic sites of PCDHGB7 were identified through univariate Cox regression analysis. We found significant differences in overall survival between patient groups with low or high methylation levels (P=0.0099). Conclusion PCDHGB7 shows significantly elevated methylation in lung adenocarcinoma, which correlates with tumor malignancy and possesses certain prognostic predictive potential.

Acute respiratory distress syndrome(ARDS)is a common respiratory emergency,but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures.Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS,but the application of hydrogen has flammable and explosive safety concerns.Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance,thus improving ARDS in patients and animal models.Coral calcium hydrogenation(CCH)is a new solid molecular hydrogen carrier prepared from coral calcium(CC).Whether and how CCH affects acute lung injury in ARDS re-mains unstudied.In this study,we observed the therapeutic effect of CCH on lipopolysaccharide(LPS)induced acute lung injury in ARDS mice.The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable,demonstrating a significant improvement compared to the untreated ARDS model group.CCH treatment significantly reduced pulmonary hemorrhage and edema,and improved pulmonary function and local microcirculation in ARDS mice.CCH promoted mitochon-drial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2(Trx2),improved lung mitochondrial dysfunction induced by LPS,and reduced oxidative stress damage.The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Objective To explore the differences between community-based population-wide early screening combined with two-way referral model and the traditional opportunistic screening model for early diagnosis of early-stage prostate cancer.Methods From August 2022 to April 2024,12815high-risk elderly males within the Fifth People's Hospital of Shanghai,Fudan University healthcare al-liance underwent population-wide prostate-specific antigen(PSA)screening across five community health centers.Among them,1005 cases with PSA＞4.0ng/ml were identified and referred via a two-way referral model to the Fifth People's Hospital of Shanghai,Fudan University for further evaluation.Prostate biopsies were performed on 445 eligible patients who consented(mean age was 65.6±6.8 years),and clinical data were collected as the community-based population-wide early screening combined with two-way referral mod-el group(Group A).During the same period,4600high-risk elderly males with lower urinary tract symptoms underwent opportunistic PSA screening at the Fifth People's Hospital of Shanghai,Fudan University identifying 700 cases with abnormal PSA levels.Biopsies were performed on 270 eligible patients who consented(mean age was 64.8±6.4 years),and clinical data were collected as the traditional op-portunistic screening model group(Group B).Baseline characteristics,positive rate of prostate cancer,clinical stages,and pathological grades were compared between the two groups.Results There were no statistically significant differences in age,PSA levels,family his-tory,body mass index(BMI),marital status and education level between the groups.There were 160 positive cases in Group A,the pos-itive rate was 35.9％,while there were 90 positive cases in Group B,the positive rate was 33.3％,with no significant statistical differ-ence(P=0.652).In Group A,100 cases(62.5％of diagnosed cases)were classified as clinical stage ≤T2N0M0,compared to 35 ca-ses(38.9％)in Group B,showing a significant statistical difference(P=0.023).Group A had 105 cases(65.6％of diagnosed cases)with International Society of Urological Pathology(ISUP)grade ≤3,while Group B had 30 cases(33.3％),showing a significant statis-tical difference(P=0.002).Conclusion Community-based population-wide early screening combined with two-way referral model showed no difference in the positive rate of prostate cancer compared to traditional opportunistic screening but exhibited advantages in diag-nosing early-stage prostate cancer.Wider adoption of this model may improve the current status of delayed staging and poor prognosis a-mong prostate cancer patients in China.

This paper analyzes the characteristics of highly cited papers published in Chinese Clinical Pharmacology and Therapeutics in the past ten years,in order to explore the influence and re-search value of these papers.Highly cited papers are an important index to evaluate the scientific re-search level of scholars and research institutions,so this study focuses on the characteristics of their number,citation frequency,number of co-authors and regional distribution.The paper uses bibliomet-rics to analyze the publication trend and citations of highly cited papers.The results show that during the observation period,the number of highly cited papers decreases year by year,and there is a signifi-cant correlation between cited frequency and publi-cation time.In addition,the number of co-authors presents a normal distribution,among which the number of co-authors is the largest,indicating that moderate cooperation has a positive effect on the influence of papers.From the perspective of geo-graphical distribution,the author group of the mag-azine is relatively dispersed,covering many regions of the country,among which Anhui,Hunan and Zhejiang have become the main sources of high-quality manuscripts.The finding reflects the maga-zine's wide reach across the country.The results of this study provide empirical support for under-standing the characteristics of highly cited papers and emphasize the importance of research collabo-ration and geographical factors in research publica-tion.Through the analysis of highly cited papers,this paper provides references for subsequent re-searchers in selecting research topics and coopera-tion methods,and also provides beneficial sugges-tions for improving the research level and influence of clinical pharmacology in China.

Through a comprehensive analysis of four cases involving repeated forensic clinical identification on the degree of human injury,disability grade,causal relationship of injury and disease,medical damage liability dispute,the reasons for the emergence of different appraisal opinions are explored.According to the reasons for the disputed conclusion,the deviation or error of the appraisal opinion can be classified in a variety of ways.Among them,the inherent limitations of theories and methods used as appraisal bases,the lack of operational skills or cognitive ability of appraisers,the unclear provisions of appraisal standards and the lack of adequacy and validity in the process of analysis and reasoning are the key reasons for the deviation or error of appraisal opinions.In light of these findings,it is necessary to strengthen the review of expert opinions in judicial practice and form a powerful error correction mechanism.

Objective To explore the mediating role of activities of daily living (ADL) in pain and depressive symptoms in the elderly in China. Methods Utilizing the data from 2020 China Health and Retirement Longitudinal Study, 4403 Chinese elderly individuals aged ≥ 60 years old were selected as the research subjects. Depression Scale (CES-D 10) of the Center for Epidemiological Survey and ADL scale were used in the study. The PROCESS4.1 macro was used to test the mediating effect of daily living activities between pain and depressive symptoms, and the Bootstrap method was applied for verification of the mediating variables. Results A total of 2368 cases of depressive symptoms were detected in the elderly in China, with a detection rate of 53.78%. Pain was positively correlated with depressive symptoms (r=0.27, P<0.01), and activities of daily living were negatively correlated with pain and depressive symptoms (r=-0.27, -0.337, P<0.01). The results showed that the total effect value of pain on depressive symptoms was 0.33, the direct effect value was 0.24, and the mediating effect value of daily living activities was 0.09, accounting for 27.27%. Conclusion Pain and activities of daily living are important factors influencing depressive symptoms in the elderly, and activities of daily living play a partial mediating role in the relationship between pain and depressive symptoms in the elderly.

Objective To measure radiation filed distribution in the treatment room of the Varian Halcyon medical linear accelerator, and to provide a basis for shielding design and potential exposure analysis of treatment rooms for this type of accelerator. Methods Under the 6 MV X-ray (FFF) mode at a maximum dose rate of 800 MU/min and a maximum irradiation field of 28.00 cm × 28.00 cm, a total of 540 MU was delivered during gantry rotation. Radiation field distribution was measured using thermoluminescence dosimeters located at multiple points in the room. The measured data were then applied to shielding calculations, and the results were compared with those obtained using empirical formulas. Results The overall radiation levels in the treatment room were in the range of 12.2 µGy/540 MU to 5.520 Gy/540 MU, with the highest dose (5.520 Gy/540 MU) observed at the isocenter, and the lowest dose (12.2 µGy/540 MU) recorded at approximately 6.5 m from the gantry head. The radiation levels at most points were within the range of 100-1000 µGy/540 MU. At heights of 0.5, 1.1, and 1.7 m, the radiation field exhibited a rapid attenuation from the beam center outward, with a faster decay along the treatment couch direction (Y-axis) than along the perpendicular direction (X-axis). Shielding calculations based on the measured radiation field yielded required wall thicknesses of 1219 mm (east wall), 949 mm (south wall), 1235 mm (west wall), and 1252 mm (north wall), all of which were smaller than those calculated using empirical formulas. Conclusion Thermoluminescence dosimeter is suitable for multi-point in situ measurement of radiation field distribution in Halcyon accelerator treatment rooms. The measurement results can be used to optimize the shielding design of Halcyon accelerator treatment rooms.

Vasculature injury occurs rarely in traumatic brain injury but increases lifetime risk of ischemic or hemorrhage stroke. The diverse and nonspecific clinical manifestations make the diagnosis and treatment of these injuries highly challenging. With advancements in device design, endovascular treatments have become widely adopted, playing an increasingly vital role in the management of vascular diseases. The purpose of this review is to introduce and summarize endovascular treatments of traumatic cerebrovascular injury and other related pathological states after traumatic brain injury. Given the innovations of neuroendovascular devices and improvements in the techniques over the past decade, this review will outline several recent advancements in endovascular treatment strategies for cerebrovascular pathologies. Popularizing more treatment options to clinicians will benefit in dealing with a variety of clinical scenarios and reduce the overall morbidity of traumatic cerebrovascular injury.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.
