BACKGROUND:To evaluate the psychological characteristics of the patients waiting for renal transplantation in order to analyze coping style, thus perform the corresponding personalized clinical psychological intervention which is conductive for patients to face reality and disease. OBJECTIVE:To investigate the psychological characteristics of the patients waiting for renal transplantation and to analyze the effect of different social factors on the coping style of patients and to explore the corresponding clinical mental intervention method METHODS:Fifty-eight patients waiting for renal transplantation and 60 patients without renal transplantation were randomly selected from Second Department of Urology, Organ transplantation Center, the 309th Hospital of PLA between February 2009 and August 2010, the patients were required to fil in a psychological questionnaire form using the currently general used medical response. The effect of social factors on the coping style and psychological stress status was analyzed with multi-factor Logistic regression analysis. RESULTS AND CONCLUSION:From the questionnaire survey, the evasive and yielding value scores of the patients waiting for renal transplantation were significantly higher than those of the patients without renal transplantation (P<0.05), but there was no significant difference of confrontation score between the patients (P>0.05). It indicated that the psychological pressure of the patients waiting for renal transplantation was bigger that of the patients with out renal transplantation, which may related with course of the disease, cost and the rejection after transplantation for the patients has to endured. Multi-factor Logistic regression analysis showed that sex, education, income, payment methods and age of the patients were al related with the confrontation, evasive and yielding scores, as those with technical secondary school education or better got the best confrontation score while those with annual income less than 60 000 yuan got the highest score in evasive and yielding styles. The results show that income and education level of patients are the main factors that affect the coping style and psychological stress status of the patients waiting for renal transplantation, treating the patients with reasonable renal clinical care interventions can help the patients face to the disease positively and can reduce the damage of transplantation to the psychology of the patients.

[Summary] The activities of 17α-hydroxylase and 17,20 lyase of cytochrome P450c17 were evaluated by ELISA in NCI-H295R cells after treatment with palmitate and oleate. The results showed that 0. 75 mmol/L plamitate did not influence the activity of 17α-hydroxylase, but increased the activity of 17, 20 lyase by 74. 3% ( P<0. 05). Oleate at the same concentration did not change the activity of 17,20 lyase. There were no significant changes in the protein expressions of P450c17, P450 oxidoreductase, and cytochrome b5 after treatment with palmitate and oleate. However,reactive oxygen species in cells were elevated by palmitate. The results suggest that exposure to palmitate may increase androgen production by inducing 17, 20 lyase activity of P450c17 in NCI-H295R cells, which is related with oxidative stress-mediated post-translational regulation of the enzyme.

OBJECTIVETo investigate infection-related mortality (IRM) after allogeneic hematopoietic stem cell transplantation in patients with refractory/relapse acute leukemia.

METHODSWe conducted a retrospective analysis of 127 patients with refractory/relapse acute leukemia and investigated the incidence, causes and risk factors of IRM.

RESULTSSixty-seven of the patients died after the transplantation. The 5-year overall survival and disease-free survival was (35.2∓5.3)% and (30.8∓5.6)% among these patients, respectively. IRM occurred in 28.3% (36/127) of the patients. Multivariate analysis showed that grade II-IV acute graft-versus-host diseases (aGVDH, P=0.049, OR=3.017) and post-transplant invasive fungal infection (P=0.032, OR=3.223) were independent risk factors of IRM.

CONCLUSIONAs a common cause of transplant-related mortality, IRM is more frequent in cases of refractory/relapse acute leukemia than in cases with a standard risk profile, and effective prophylaxis and treatment of severe GVHD remain currently the primary measures for reducing post-transplant IRM.

Objective:To assess respondents' understanding of the Physical Activity Questionnaire for Chronic Kidney Disease (CKD-PAQ) in Chinese and revise the items.Methods:The CKD-PAQ was sinicized according to the FACIT translation model to form a preliminary version. Using the purposive sampling method, 40 patients with chronic kidney disease from Shenzhen Traditional Chinese Medicine Hospital were selected as respondents for three rounds of cognitive interviews from July to August 2023. Targeted content analysis was used to understand the level of understanding of the initial version of the questionnaire. Based on the respondents' suggestions, the questionnaire's final version was obtained after discussing and negotiating the questionable items.Results:The CKD-PAQ contained four dimensions and 31 items. A total of 22 questions were identified in three rounds of interviews. The results of the first round of interviews show that 13 questions need to be revised in terms of understanding and expression, the results of the second round of interviews show that eight questions need to be revised in terms of understanding and expression, the results of the third round of interviews showed that the language understanding of the revised Chinese version was consistent with the original questionnaire.Conclusions:Cognitive interviews can improve respondents' understanding of the questionnaire and identify issues that are difficult to identify during the localization process, thus improving the accuracy of the questionnaire.

Objective : To explore the relationship between the methylation level of RABL6 in peripheral blood and early lung cancer (LC) with a case-control study in the Chinese population． Methods : The methylation levels of 7 CpG sites in RABL6 gene in peripheral blood of samples from 275 LC patients (81．5% at stage I) ，and age- and gender-matched 185 benign lung nodule cases and 267 matched healthy controls were measured by matrix-assisted laser desorption ionization time-of-flight mass spectrometry．Multinomial Logistic regression adjusted for covariates was used to analyze the association between the RABL6 methylation and LC．Mann-Whitney U test was applied for the comparisons of RABL6 methylation levels between clinical characteristics subgroups of LC. Results : Compared to the healthy controls，the methylation of RABL6 _CpG_ 17 was inversely associated with LC in females ( per - 10% methylation : OR = 2. 47，95% CI = 1. 19－5. 13，P = 0. 016) ，but positively associated with LC in males (per - 10% methylation : OR = 0. 52，95% CI = 0. 29－0. 94，P = 0. 030) ．In addition，hypermethylation of RABL6_CpG _2 and RABL6_CpG_5 was significantly associated with LC in the subjects older than 55 years (for RABL6_CpG_ 2 : per －10% methylation : OR = 0. 77，95% CI = 0. 60－0. 99，P = 0. 038 ; for RABL6_CpG_5 : OR = 0. 58，95% CI = 0. 34－0. 97，P = 0. 038) ． Conclusion The study reveals an association between peripheral blood-based RABL6 methylation levels and early LC，providing a new clue for developing peripheral blood-based DNA methylation as a potential marker for the evaluation of LC risk.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.
