Objective To explore the prevalence of depressive symptoms in postoperative patients with ovarian cancer and to analyze its influencing factors from multiple dimensions, including clinical characteristics, psychological factors, and laboratory indicators. Methods A cross-sectional study was conducted, which enrolled 235 postoperative patients with ovarian cancer. Depressive status was assessed using the patient health questionnaire, and the demographic, pathological, and medical record data of the patients were collected using the generalized anxiety disorder scale, Pittsburgh sleep quality index, European organization for research and treatment of cancer quality of life questionnaire core 30, and ECOG performance status score. Peripheral blood tumor marker (CA125), routine blood test, lymphocyte subsets, and serum cytokine levels were measured. Univariate and multivariate binary logistic regression analysis were used for statistical analysis. Results The prevalence of depression in postoperative patients with ovarian cancer was 39.15% (92/235). Univariate analysis showed that ECOG score ≥ 2 points, pain, anxiety, poor sleep quality, low quality of life, low life satisfaction, tumor recurrence, six or more cycles of chemotherapy, as well as higher levels of CA125, NLR, and NAR, and lower hemoglobin levels were significantly associated with depression (all P<0.05). Multivariate binary Logistic regression analysis showed that anxiety (OR=1.975, 95%CI: 1.231-3.170), sleep efficiency (OR=4.181, 95%CI: 1.211-14.43), sleep latency (OR=34.806, 95%CI: 4.258-284.542), ECOG performance status score, cognitive function (OR=0.918, 95%CI: 0.868-0.97), and life satisfaction were independent risk factors for depression (all P<0.05). Laboratory indicators were not independent influencing factors in the multivariate Logistic regression model. Conclusion Depression in postoperative patients with ovarian cancer is influenced by physiological, psychological, and social factors. Clinical management should focus on patients with anxiety, sleep disorders, poor physical condition, and low life satisfaction, and a comprehensive prevention and treatment strategy centered on psychological intervention and taking into account symptom management and social support should be implemented.

Objective:To construct a management model of data mining for medical imaging equipment,so as to improve the quality of managing equipment.Methods:A management model of mining data was constructed to manage medical imaging equipment.A total of twenty imaging equipment that were using at Hainan Hospital of the General Hospital of the People's Liberation Army of China from April 2022 to March 2024 were selected.According to different management methods,the conventional management was adopted to manage them during April 2022 to March 2023,and the management model of mining data(model management)was adopted to manage them during April 2023 to March 2024.A self-developed questionnaire was used to conduct a satisfaction survey for imaging physicians,staffs of operating and maintaining equipment,and technicians who using and managing equipment,and patients who received diagnosis and treatment by using equipment.The failure rate and the imaging effect of equipment,the satisfaction scores of the relative staffs who used equipment,and the growth amplitude of operational benefits of equipment between two management methods were compared.Results:A total of 20 failures occurred in imaging equipment that adopted model management.In them,the failure rates of the self-equipment,improper operation and insufficient professional level were respectively 15%,5%and 5%,all of which were lower than those of the conventional management method.The predicted failure rate of model management was 75%,which was higher than that of the conventional management method,and the differences of the above indicators between two methods were statistically significant(x2=6.547,4.392,5.124,6.701,P<0.05).The scores of image clarity,qualification rate,excellent rate,qualification rate of body position,and the total score of imaging effect of adopting model management method were respectively(22.36±2.01),(23.21±1.54),(22.65±1.87),(23.21±1.52)and(91.43±6.77)points,all of which were higher than those of the conventional management method,and the differences were statistically significant(t=10.662,12.727,15.324,16.333,13.742,P<0.05).The satisfaction scores of imaging physicians,staffs of operation and maintenance,technicians and patients who uses management for adopting the model management method were all higher than those of the conventional management method,and the differences were statistically significant(t=13.586,14.249,17.021,11.006,P<0.05).The average values of growth amplitude of cost and benefit of equipment operation of adopting model management method were higher than those of the conventional management method,and the average value of the growth amplitude of the cost of the troubleshooting of model management method was lower than that of the conventional management method,and the differences of them were statistically significant(t=15.057,19.310,18.336,P<0.05).Conclusion:The application of the management model of data mining for medical imaging equipment can provide warning of equipment failures in advance,and reduce the failure rate of equipment,and improve the quality of management and operation of equipment,and enhance the service level of equipment.

Objective:To investigate the association between peripheral immune function status and lung cancer metastasis,and to identify peripheral blood immune biomarkers for'Deficiency of Vital Qi'assessment in lung cancer metastasis.Methods:A retrospective analysis was conducted on peripheral blood immune markers collected before treatment from lung cancer patients admitted into Shanghai Municipal Hospital of Traditional Chinese Medicine,affiliated to Shanghai University of Traditional Chinese Medicine,between March 2023 and April 2025.Patients were categorized into the non-metastatic and the metastatic groups based on the presence of distant metastasis,and the differences in the expressions of immune cells and cytokines between groups were compared.Peripheral blood immune markers with P<0.05 in univariate analysis were incorporated into a multivariate binary logistic regression model to identify independent predictors of lung cancer metastasis.Results:A total of 193 lung cancer patients were included(101 in the non-metastatic group and 92 in the metastatic group).There were no statistically significant differences between the two groups in terms of gender,age,smoking history,drinking history,or pathological type(all P>0.05).Univariate analysis revealed significant differences in multiple immune markers between the non-metastatic and metastatic groups(all P<0.05),including:lymphocyte count,CD3+,CD4+,and CD8+T,CD19+B cells,absolute counts of CD3-CD16+CD56+NK cells,percentages of Treg cells,CD8+CD28+Treg cells,G-MDSC,and CD3-CD16+CD56+dim NK cells,and levels of cytokine IL-1β,IL-6,and IL-10.Binary logistic regression analysis of differential indicators suggested that the percentage of Treg cells and CD8+CD28+Treg cells in peripheral blood were independent predictors of distant metastasis in lung cancer(OR=1.193,95%CI[1.047,1.36],P<0.01;OR=0.978,95%CI[0.957,0.999],P<0.05).Conclusion:Peripheral blood immune dysfunction is the biological basis for'qi deficiency'in lung cancer metastasis.This study quantitatively demonstrates the correlation between peripheral immune function status and lung cancer metastasis,providing empirical evidence for the theories of'qi deficiency and hidden toxicity'and'metastatic state of tumors'.

Objective To compare the efficacy of precut over a pancreatic duct stent(PPDS)and transpancreatic precut sphincterotomy(TPS)for difficult biliary cannulation in endoscopic retrograde cholangiopancreatography(ERCP).Methods A retrospective analysis was conducted on the clinical data of all consecutive patients underwent ERCP by the same doctor in our hospital between April 2019 and March 2023.According to the selected method during difficult biliary cannulation when guidewire entered pancreatic duct unintendedly,the patients were divided into two groups,1)PPDS group:placing a pancreatic duct stent first,then using a needle knife to cut bile duct sphincter on the surface of the pancreatic duct stent,preserving pancreatic duct sphincter,and then selectively cannulate bile duct;2)TPS group:precut through pancreatic duct sphincter first,then a pancreatic duct stent was placed,and bile duct was selectively cannulated.The success rate of biliary cannulation and ERCP-related complication between the two groups were compared.Results Among 762 ERCP patients,84 patients were enrolled in this study,44 patients in PPDS group,and 40 patients in TPS group.In PPDS group,42 patients(95.4%,42/44)had successful biliary cannulation.No post-ERCP pancreatitis(PEP),bleeding,perforation occurred in PPDS group.In TPS group,39 patients(97.5%,39/40)had successful biliary cannulation.Four patients(10.0%,4/40)had PEP in PPDS group,no bleeding or perforation occurred.All patients were cured.The success rate of biliary cannulation between two groups had no significant difference(P>0.05),while the rate of PEP had significant difference(P<0.05).Conclusions Both PPDS and TPS are good choice for difficult biliary cannulation with high success rate of biliary cannulation.PPDS is more suitable for patients with high-risk factors for PEP,while TPS is a simple technique.

Objective To assess the comparative efficacy of different methods for difficult biliary cannulation in endoscopic retrograde cholangio-pancreatography(ERCP)through a network meta-analysis.Methods Randomized controlled trials(RCTs)that compared the efficacy of different adjunctive methods(early or late needle-knife technique,pancreatic guidewire-assisted technique,pancreatic stent-assisted technique,transpancreatic sphincterotomy,persistent standard cannulation technique)for difficult biliary cannulation with each other were identified.The success rate of biliary cannulation and the incidence of post-ERCP pancreatitis(PEP)were the outcomes of interest.Pairwise and network meta-analysis and ranking according to surface under the cumulative ranking curve(SUCRA)for all methods were performed.Results Eighteen RCTs were identified according to selection criteria,and 2 033 patients were enrolled.The use of transpancreatic sphincterotomy over persistent standard cannulation technique(RR=1.34,95%CI:1.02-1.77)and over pancreatic guidewire-assisted technique(RR=1.26,95%CI:1.00-1.60)significantly increased the success rate of biliary cannulation.Based on SUCRA ranking,transpancreatic sphincterotomy followed by early needle-knife techniques were ranked highest in terms of increasing the success rate of biliary cannulation.Only early needle-knife technique significantly decreased PEP rate when compared with persistent standard cannulation technique(RR=0.53,95%CI:0.30-0.94),whereas both early needle-knife techniques and transpancreatic sphincterotomy led to lower PEP rates as compared with pancreatic guidewire-assisted technique(RR=0.41,95%CI:0.17-0.99;RR=0.49,95%CI:0.25-0.96;respectively).Based on SUCRA ranking,early needle-knife technique followed by transpancreatic sphincterotomy were ranked highest for decreasing the PEP rate of biliary cannulation.Conclusions Transpancreatic sphincterotomy increases the success rate of difficult biliary cannulation in ERCP;early needle-knife technique and transpancreatic sphincterotomy are superior to other interventions in decreasing PEP rates and should be considered as a choice of difficult biliary cannulation.

Photothermal therapy has been intensively investigated for treating cancer in recent years. However, the long-term therapeutic outcome remains unsatisfying due to the frequently occurred metastasis and recurrence. To address this challenge, immunotherapy has been combined with photothermal therapy to activate anti-tumor immunity and relieve the immunosuppressive microenvironment within tumor sites. Here, we engineered silica-based core‒shell nanoparticles (JQ-1@PSNs-R), in which silica cores were coated with the photothermal agent polydopamine, and a bromodomain-containing protein 4 (BRD4) inhibitor JQ-1 was loaded in the polydopamine layer to combine photothermal and immune therapy for tumor elimination. Importantly, to improve the therapeutic effect, we increased the surface roughness of the nanoparticles by hydrofluoric acid (HF) etching during the fabrication process, and found that the internalization of JQ-1@PSNs-R was significantly improved, leading to a strengthened photothermal killing effect as well as the increased intracellular delivery of JQ-1. In the animal studies, the multifunctional nanoparticles with rough surfaces effectively eradicated melanoma via photothermal therapy, successfully activated tumor-specific immune responses against residual tumor cells, and further prevented tumor metastasis and recurrence. Our results indicated that JQ-1@PSNs-R could serve as an innovative and effective strategy for combined cancer therapy.

Objective To investigate the availability and safety of pulmonary rehabilitation for hospitalized patients with acute exacerba-tion of chronic obstructive pulmonary disease (COPD). Methods Seventy-two hospitalized patients with acute exacerbation of COPD were randomly included into test group (n=36) and control group (n=36) from June, 2015 to June, 2016. All the patients accepted management of anti-infection, phlegm elimination, antiasthma, etc., as well as the guidance of expectoration and health education; while the test group ac-cepted pulmonary rehabilitation from the third day of admission to discharge. Their strength of hand grip, 1-minute sit-to-stand test (STST), the days of hospitalization, lung function parameters, modified Medical Research Council (mMRC) scores and COPD Assessment Test (CAT) scores were measured before and after treatment. Results Compared with the control group, the strength of hand grip (t=2.985, P<0.01) and number of STST (t=2.024, P<0.05) increased, while the scores of CAT (t=3.222, P<0.01) and mMRC (t=2.212, P<0.05) de-creased in the test group. The hospital stay seemed to be shorter in the test group than in the control group, but there was no significant dif-ference (t=1.433, P>0.05). There was no significant difference in lung function after treatment in both groups (Z<1.031, P>0.05). Conclu-sion Pulmonary rehabilitation is effective on hospitalized patients with acute exacerbation of COPD in muscle strength, capability of activi-ties, and relieve the symptoms.
