Pituitary stalk interruption syndrome(PSIS) typically manifests initially as short stature due to growth hormone deficiency(GHD). Untreated chronic GHD may induce metabolic disturbances, leading to non-alcoholic fatty liver disease with rapid progression to liver cirrhosis. Liver cirrhosis can subsequently cause hepatopulmonary syndrome, resulting in hypoxemia and dyspnea. This article reports a case of a young male presenting with short stature, dyspnea, liver cirrhosis, and hepatopulmonary syndrome, ultimately diagnosed with PSIS. Following recombinant human growth hormone(rhGH) and other hormonal replacement therapies, the patient exhibited improvement in hepatic steatosis and fibrosis, with alleviation of dyspnea. Through analysis of this case, we provide clinical insights for diagnosing and managing cirrhosis and hepatopulmonary syndrome in such patients, highlighting that early diagnosis and timely initiation of rhGH replacement therapy can improve prognosis and quality of life.

Objective:To evaluate the safety and effectiveness of fuzuloparib for the treatment of ovarian epithelial cancer patients in the real world setting.Methods:A retrospective analysis was conducted on the baseline data of 4 620 ovarian cancer patients who had received fuzuloparib monotherapy or combination therapy. Another 224 ovarian cancer patients who were willing to receive fuzuloparib monotherapy or combination therapy were prospectively enrolled, and their baseline characteristics, drug effectiveness, and safety data were analyzed.Results:(1) Among the 4 620 patients in the retrospective cohort, the median age of patients was 60 years; tumor types: 89.8% (4 149/4 620) had ovarian cancer. Among patients with clearly documented information, the vast majority had a histological type of serous carcinoma (82.9%, 3 770/4 546) and International Federation of Gynecology and Obstetrics (FIGO) staging of Ⅲ-Ⅳ (90.9%, 1 537/1 691). (2) Among the 224 patients in the prospective cohort, the median age of patients was 57 years; tumor types: 83.9% (188/224) had ovarian cancer. Among patients with clearly documented records, the predominant pathologic type was serous carcinoma (91.9%, 193/210), and FIGO stage was Ⅲ-Ⅳ in 79.9% (139/174). (3) Among the 224 prospective patients: 84 patients received first-line fluzoparib maintenance therapy, 92 patients received fluzoparib maintenance therapy after platinum-sensitive recurrence, 23 patients received direct fluzoparib treatment after platinum-sensitive recurrence, 19 patients received direct fluzoparib treatment after platinum-resistant recurrence. The median follow-up durations were 8.5, 8.7, 7.9, and 6.7 months, respectively. The median durations of fluzoparib treatment were 6.7, 4.8, 3.1, and 1.9 months, respectively. The median progression-free survival (PFS) times were not reached during follow-up, 12.6 months, not reached during follow-up, and 4.8 months, respectively. The 1-year PFS rates were 84.1%, 55.0%, 69.8%, and 45.5%, respectively. The remaining 6 patients received other fluzoparib regimens. (4) Among the 224 patients in the prospective dataset, 205 had safety data recorded. Of these, 127 patients (62.0%, 127/205) experienced treatment-related adverse events, with common events including anemia (24.4%, 50/205), thrombocytopenia (21.0%, 43/205), and leukopenia (19.5%, 40/205). Among the 205 patients, 43 (21.0%, 43/205) experienced grade 3 or higher treatment-related adverse events, with common events including anemia (8.3%, 17/205) and thrombocytopenia (8.3%, 17/205).Conclusions:The effectiveness of fuzuloparib in clinical application is generally consistent with other drugs in the same class, with good safety. This study provids new clinical evidence for the treatment of ovarian cancer with fuzuloparib.

BackgroundIn Sichuan Province， most healthcare institutions providing mental health services have adopted self-developed evaluation indicators for the quality of nursing care in psychiatric closed wards， lacking unified standards. This results in insufficient authority and homogeneity， which is unfavorable for the standardized assessment and continuous improvement of nursing quality. ObjectiveTo construct a standardized evaluation indicator system for nursing quality of psychiatric closed wards in Sichuan Province， so as to provide references for nursing quality management and assessment. MethodsBased on bio-psycho-social medical model and guided by "Structure-Process-Outcome" quality evaluation framework， preliminary evaluation indicators for nursing quality in psychiatric closed wards were developed through literature analysis， research team discussions and clinical experience. Through two rounds of Delphi expert consultation， the indicators were revised and finalized. ResultsThe response rates for two rounds of Delphi expert consultation questionnaire were 100%. The expert authority coefficients were 0.845 and 0.864， respectively， and the Kendall's coordination coefficients ranged from 0.119 to 0.210 （P<0.01）. Ultimately， a nursing quality evaluation index system for psychiatric closed wards was established， comprising 3 first-level indicators， 9 second-level indicators and 46 third-level indicators. ConclusionThe nursing quality evaluation indicators for psychiatric closed wards constructed based on the Delphi method can provide references for nursing quality management and evaluation in such wards. ［Funded by Research Project Fund of Sichuan Nursing Society （number， H20004）； Sichuan Hospital Association Hospital Management Research Special Fund （number， YG2323）］

BACKGROUND:Protein is one of the essential nutrients for the human body and is a key component of human cell tissue.Protein supplementation can promote the synthesis of myofibrillar protein and play a key role in strength training.However,the interaction mechanism and signaling pathway between protein and exercise are still unclear.OBJECTIVE:To explore the mechanism of interaction between exercise and protein,and to optimize the benefits of protein supplementation on exercise performance.METHODS:Using"sports,proteins,amino acids,polypeptide,interaction mechanisms,signaling pathway"as Chinese and English search terms,we searched WanFang Data,CNKI,VIP,and PubMed databases respectively.Articles were screened according to the inclusion criteria,and finally 73 articles were included in the review.RESULTS AND CONCLUSION:Current research on protein supplementation promoting exercise performance mainly focuses on promoting muscle growth,endurance improvement,and body recovery through protein supplementation,but there are differences in the existing experimental results.The interaction mechanism between protein molecules and proteins in the body is not yet clear.The research on the interaction mechanism between exercise and peptides is still in its infancy.Exercise can stimulate the full absorption of external protein intake,which can affect the mechanism of protein molecules in the body.Supplementing peptide nutrition can more accurately affect the body's state,thus better eliminating the phenomena of"sub-health"and"modern diseases."Therefore,studying the interaction mechanism between exercise and proteins is particularly important,delving into the specific mechanisms by which amino acids act on the body,and further exploring the interaction mechanism between exercise and peptides.

Ferroptosis is a form of iron-dependent cell death caused by a disorder of iron lipid metabolism.Its mechanism mainly includes lipid metabolism and iron metabolism,which are complicated and strictly regulated by various metabolic and signaling pathways.Current studies have shown that ferroptosis is associated with cancer,atherosclerosis,and neurological diseases.Traditional Chinese medicine(TCM)is characterized by various active ingredients,relatively high safety,and lower treatment costs,which possess unique advantages in clinical applications.It has been widely used in the treatment of various diseases.Taking the regulation of ferroptosis by traditional Chinese medicine as the entry point may be a new direction for the future prevention and treatment of various diseases.In this review,we discussed the mechanism of iron lipid metabolic disorders based on ferroptosis and the research progress of traditional Chinese medicine intervention to provide reference and treatment strategies for the prevention and treatment of related diseases.

Objective To investigate the removal of metal artifacts caused by different metal implants in different parts of the human body using dual-energy CT and to select the best method for metal artifacts reduction.Methods Forty-three patients with metal implants underwent dual-energy CT scans.Reconstructed images were obtained to produce eight sets of imaging data:conventional image(CI),120 keV,140 keV,160 keV,180 keV,200 keV,Orthopedic metal artifact reduction algorithm(O-MAR),200 keV+O-MAR.The optimal spectral monoenergetic images was selected based on the trend of changes in artifact index(AI)values with different keV monoenergetic images and subjective evaluation.One-way ANOVA was used to analyze and compare objective image evaluation indi-cators and subjective evaluations of image quality among different groups.The intraclass correlation coefficient(ICC)was used to evaluate the consistency and reliability of subjective evaluations of image quality among different observers.Results The AI values of differ-ent keV monoenergetic images showed a decreasing trend with increasing keV,and the virtual monoenergetic images at the 200 keV level had the smallest AI value.There were statistically significant differences in objective indicators for the removal of high-density artifacts and low-density artifacts among the groups(P＜0.05).Pairwise comparison showed statistical differences between CI and O-MAR,CI and O-MAR+200 keV,200 keV and O-MAR,200 keV and O-MAR+200 keV(P＜0.05),with O-MAR+200 keV demon-strating the best objective indicators.The ICC for subjective evaluation among different observers was 0.97％,and the ICC within observers was 0.91％.There were statistically significant differences in subjective image scores among the groups(P＜0.05),with the CI had the lowest score[(1.04±0.24)points]and the O-MAR+200 keV combination had the highest score[(4.57±0.78)points].Conclusion Dual-energy CT virtual monoenergetic 200 keV spectroscopy combined with O-MAR technique can be used as the best technique for removing metal implant artifacts and achieving better contrast in the surrounding soft tissue of prostheses.

Objective To develop and validate a nomogram model for predicting the risk of kinesiophobia in patients after lung cancer surgery.Methods A total of 164 lung cancer patients who underwent surgery in a Grade ⅢA hospital in Xiamen were recruited from October 2022 to May 2023 in this study.Logistic regression was conducted to identify independent risk factors of kinesiophobia in patients who recieved lung cancer surgery.A Nomogram model was developed using R software for predicting the risk of kinesiophobia.The predictive performance of the model was assessed by calculating the receiver-operating-characteristics curve(ROC)and the area under curve(AUC).Results The incidence of postoperative kinesiophobia in lung cancer patients was at 44.51％.Logistic regression analysis showed that pain and fatigue were the risk factors for the occurrence of postoperative kinesiophobia in the patients(P<0.05)and self-efficacy was a protective factor(P<0.05).Validation of the Nomogram model showed that the ROC curve indicated an AUC of 0.888(95％CI 0.836-0.940)for predicting kenesiophobia in patients after lung cancer surgery and the calibration curve presented as a line with a slope close to 1.The Hosmer-Lemeshow goodnee-of-fit test showed that the model could accurately predict the risk of postoperative kinesiophobia in lung cancer patients(χ 2=1.931,P=0.983).Conclusion Self-efficacy,pain and fatigue are the influencing factors for the occurrence of postoperative kinesiophobia in the patients who received lung cancer surgery.The nomogram prediction model has good accuracy and discrimination,and it may assist the healthcare professionals to predict the occurrence of postoperative kinesiophobia in the patients after lung cancer surgery and take pertinent measures to minimise the incidence.
