Objective:To explore different types of psychological reactions of spouses of young and middle-aged breast cancer patients and their influencing factors based on potential profile analysis, so as to provide reference for targeted intervention in clinical practice.Methods:A cross-sectional investigation method was used to select the spouses of middle-aged and young patients with breast cancer who were hospitalized in the Second Affiliated Hospital of Guilin Medical University, Quanzhou County People's Hospital, and Bobai County People's Hospital from January 2023 to June 2024. General Data Questionnaire, Spousal Psychological Response Scale of Breast Cancer Patients, Perceived Partner Responsiveness Scale and Perceptive Social Support Scale were used to investigate. The potential profile analysis of spousal psychological reaction of young and middle-aged breast cancer patients was carried out, and the influencing factors of different categories were analyzed by ordered multiple Logistic regression.Results:A total of 232 questionnaires were distributed, and 211 valid questionnaires were collected, with an effective response rate of 91.0%.The spouses of 211 middle-aged and young patients with breast cancer were 30-59 (43.25 ± 2.58) years old. The total psychological response score was (69.96 ± 8.36). The low psychological response high coping group accounted for 24.6% (52/211), the moderate psychological response group accounted for 33.2% (70/211), and the high psychological response low coping group accounted for 42.2% (89/211). The results of ordered multiple Logistic regression analysis showed that cumulative care time, tumor stage of patients, perceived partner responsiveness, and perceived social support were the influencing factors of potential categories of psychological responses of spouses of young and middle-aged breast cancer patients ( OR values were 0.014-0.304, all P<0.05). Conclusions:There is heterogeneity in the psychological reactions of spouses of young and middle-aged breast cancer patients. According to the characteristics of the classification, the nursing staff should formulate targeted intervention strategies, focusing on improving the perceived partner responsiveness, establishing an effective social support system, and reducing the level of psychological response.

Objective To explore the mechanism of micro ribonucleic acid(miR)-3197 in diabetic retinopathy(DR)on the basis of the nuclear factor κB(NF-κB)signaling pathway.Methods A total of 47 DR patients admitted to Heng-shui People's Hospital from January 2021 to December 2021 were selected as the DR group,and 47 healthy individuals in the same period were collected as the control group.Their information in gender,age,fasting blood glucose(FBG),fast-ing insulin(FINS),triglycerides(TG),total cholesterol(TC)and miR-3197 were compared.The correlation between miR-3197 in DR patients and laboratory data was analyzed,and the receiver operating characteristic(ROC)curve of miR-3197 for DR diagnosis was drawn.The human retinal microvascular endothelial cells(hRMECs)were cultured in vitro and treated with 5.5 mmol·L-1 glucose[low glucose(NG)group]and 30 mmol·L-1 glucose[high glucose(HG)group],respectively.After transfecting with anti-miR-NC and anti-miR-3197,the cells were treated with 30 mmol·L-1 glucose(HG+anti-miR-NC group and HG+anti-miR-3197 group).Real-time fluorescence quantitative PCR was used to detect the relative expression level of miR-3197,flow cytometry was used to detect the apoptosis rate of hRMECs,enzyme-linked im-munosorbent assay was used for detecting tumor necrosis factor-a(TNF-a)and interleukin-6(IL-6),and Western blot was adopted to detect the expressions of aspartic protease 3 containing cysteine(cleaved caspase-3)protein,Bax protein and NF-κB signaling pathway-related proteins[phospho-NF-KB p65(p-p65),p65,phospho-NF-KB inhibited protein(p-IκBα),and NF-κB inhibited protein(IκBα)].Results The levels of FBG,FINS,TC and TG in the DR group were higher than those in the control group,and the differences were statistically significant(all P＜0.001).The relative expression level of miR-3197 in the peripheral blood of patients in the DR group(2.76±0.67)was higher than that of the control group(1.03±0.34),and the difference was statistically significant(P＜0.05).The miR-3197 level of patients in the DR group was positively correlated with FBG,FINS,TC and TG levels(r=0.672,0.587,0.511 and 0.423;all P＜0.05).The ROC curve graph showed that the area under the curve was 0.919,with sensitivity and specificity of 85.11％and 89.36％,respectively.Compared with the NG group,the HG group showed a significant increase in cell apoptosis rate and the pro-tein expressions of cleaved caspase-3,Bax,TNF-a,IL-6,p-IκBa and p-p65(all P＜0.05);compared with the HG+anti-miR-NC group,the HG+anti-miR-3197 group showed a significant decrease in cell apoptosis rate and the protein expres-sions of cleaved caspase-3,Bax,TNF-a,IL-6,p-IκBa and p-p65(allP＜0.05).Conclusion The miR-3197 is highly ex-pressed in the peripheral blood of DR patients and high glucose-induced hRMECs.Down-regulation of miR-3197 can allevi-ate high glucose-induced hRMEC apoptosis and inflammatory injury,and its mechanism of action may be related to the inhi-bition of the NF-κB signaling pathway.

Objective:The clinical features, laboratory indices, and imaging data of patients with Pneumocystis jirovecii pneumonia (PJP) were described and analyzed, aiming to provide helpful information for the diagnosis and treatment of PJP. Methods:A retrospective study were conducted with data from 154 PJP patients who visited China-Japan Friendship Hospital from May 2017 to August 2020. Their clinical characteristics, laboratory and imaging data, and clinical outcomes were collected for analysis. The patients were further divided into the death group (51 cases) and the survival group(103 cases). The differences between the groups were compared by using t-test, nonparametric test, and chi-square test. Results:Of the 154 PJP patients, there were 89 males and 65 females, with a mean age of (53.7±14.8) years. Among them, 85.7% (132/154) were on immunosuppressive/glucocorticoids agents within the past month. Besides, 27.9% (43/154) and 33.1% (51/154) had kidney diseases and connective tissue diseases, respectively. The major clinical manifestations in these patients involved fever 82.9% (126/154), cough 59.7% (92/154), and dyspnea 52.6% (81/154). For the laboratory data, the lactate dehydrogenase (LDH) was 561.0 (434.3, 749.0) IU/L and the value increased in 91.3% (95/104) of the patients. The CD4+T-cell lymphocytes in 88.0% (95/108) and 57.4% (62/108) of patients were lower than 400/μl and 200/μl, respectively. Furthermore, (1, 3)-β-D glucan (BG) increased in 74.4% (67/90) of PJP patients (≥100.0 ng/L). For the imaging results, chest computed tomography (CT) showed diffuse ground-glass shadows/grid shadows in 90% (117/130) patients. Compared with the survival group, higher LDH [690.5 (528.8, 932.3) IU/L vs 502.5 (381.8, 657.0) IU/L, Z=-3.375, P=0.001], white blood cell count (WBC) [9.8 (5.8, 12.6) ×10 9/L vs 7.3 (5.0, 10.1) ×10 9/L, Z=-2.392, P=0.017], and age [(69.8±14.5) years vs (50.6±14.0) years, t=-3.756, P=0.001] were found in the death group. Lower lymphocyte ratio [5.3 (3.2, 9.3) % vs 9.6 (5.6, 17.2) %, Z=?3.262, P=0.001] and oxygen partial pressure (PaO 2) levels [(73.2±20.5) mmHg vs (64.8±17.7) mmHg (1 mmHg=0.133 kPa), t=2.345, P=0.021] were also observed in the death group. Furthermore, in the death group, the bacterial and fungal infection rate was higher than the rates in the survival group [55.1% (27/51) vs 21.5% (22/103), χ 2=15.372, P=0.001]. Conclusions:Long-term use of immunosuppressive agents or glucocorticoids predispose to PJP. CD4+T-lymphocytes, LDH, and BG might be used as important auxiliary examinations for PJP patients. Age, LDH, WBC, lymphocyte ratio, PaO 2 and possible combinations with bacterial or fungal infections are more closely related to the prognostic of PJP patients.
