OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events （irCAEs） caused by durvalumab， and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history， and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile， the clinical pharmacists conducted a graded assessment of the adverse reaction， proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids， assisted physicians in restarting immunotherapy， and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion， and after symptomatic treatment， the patient’s skin symptoms improved， and discharged with medication. After the completion of glucocorticoid therapy for the patient， the physician restarted immunotherapy with tislelizumab， and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice， it is crucial to promptly identify and discontinue suspicious drugs， immediately implement effective symptomatic treatment measures， and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

Hepatocellular carcinoma （HCC） is a common malignant tumor with a high mortality rate， an insidious onset， and complex pathological mechanisms. In the tumor microenvironment， tumor-promoting immune cells protect tumor cells from immune attacks， while dysfunction of anti-tumor immune cells causes the inhibition of immune response， thereby leading to the continuous deterioration of cancer. In recent years， traditional Chinese medicine has shown good efficacy in the treatment of HCC， and it can inhibit the proliferation and metastasis of cancer cells by regulating immune cells. By analyzing related articles in China and globally， this article summarizes how immune cells affect the progression of HCC through the immunosuppressive pathway and how traditional Chinese medicine exerts an anti-HCC effect by regulating immune cells， in order to provide theoretical basis and reference for optimizing the treatment of HCC.

OBJECTIVE: To establish a three-dimensional finite element model of a digital wire loop space maintainer for the mandible and primary tooth loss, in order to investigate the stress, deformation, and shear force experienced by patients with the loss of the second primary molar when wearing the wire loop space maintainer. METHODS: Cone beam computed tomography (CBCT) scans were performed on the patients to create a digital model of the mandible with the absence of the second primary molar using Mimics 21.0 software. A digital model integrating the crown's retention and the wire loop structure of the full crown and ring wire loop space maintainer was constructed using pediatric space maintainer design software, utilizing three different materials: cobalt-chromium alloy, polyether ether ketone (PEEK), and titanium alloy. In ANSYS Work Beach 2023 R2 software, vertical loads of 70 N, tilted 45° along the long axis of the tooth loads of 70 N, and a 10 N load on the surface of the wire loop were applied to the occlusal surfaces of models 46 and 84, simulating centric and lateral occlusions during chewing with the wire loop space maintainer in place. The stress states of the wire loop space maintainer and supporting teeth were analyzed. RESULTS: Under various loading conditions, the maximum principal stress of the ring wire loop space maintainer was significantly lower than that of the full crown. Stress contour maps indicated that the peak of the maximum principal stress occurred at the junction of the wire loop and crown structure, indicating that this area was more susceptible to fracture. The ring wire loop space maintainer made from PEEK material exhibited the lowest maximum shear stress on the internal organizational surfaces, with equivalent stresses of 23.18 MPa and 36.35 MPa for models 46 and 84, respectively. Stress contour maps demonstrated that the maximum stress on tooth 46 was located at its mesial, while the maximum stress on tooth 84 was situated near the root area on its distal, in contact with the wire loop space maintainer. CONCLUSION In cases of second primary molar loss, wearing the digital ring wire loop space maintainer can effectively distribute stress, and the ring wire loop space maintainer made from PEEK material reduces the stress experienced by supporting teeth to some extent, demonstrating its superiority in clinical application.

The heating electrospray ionization was used for positive and negative ion mode scanning. The scanning range was m/z 50-1 500， and the spray voltage was 2 kV （positive ion mode） and 1.5 kV （negative ion mode）. The information of chemical constituents of modified Yupingfengsan formula was collected through literature review to establish a database； the structure of the constituent was identified based on the above database， relevant literature， and chromatography and mass spectrometry information of reference standards. RESULTS & CONCLUSIONS Totally 114 chemical constituents were identified from modified Yupingfengsan formula， including 31 flavonoids， 39 phenylpropanoids， 5 saponins， 8 terpenoids， 3 chromones， 3 curcuminoids， etc. Based on the comparison of reference standards， 8 constituents were ultimately determined， including magnoflorine， calycosin， calycosin glycoside， cimifugin， 5-O-methylvisammioside， sec-O- glucosylhamaudol， luteolin and mangiferin. These constituents mainly involved glycosylation cleavage， retro Diels-Alder fragmentation， glycosylation loss， neutral molecule loss and other fragmentation pathways.

Objective:To explore the role of serum cholinesterase (CHE) levels in the prognosis of patients with acute decompensated heart failure (ADHF).Methods:Total of 244 consecutive patients with ADHF who were admitted to the emergency department and were successfully discharged were prospectively enrolled from January 2018 to June 2020. Patients were divided into groups according to the first and third quartile of CHE level and the clinical data, laboratory tests and other nutritional indices were recorded after discharge, and then were followed up. The primary end points were the composites of cardiovascular death and hospitalization for worsening HF (composite end points). The secondary end points were all-cause mortality and cardiovascular death. Cox proportional risk analysis, time-dependent Cox regression model or stratified cox regression were used to identify the risk of primary and secondary endpoints. Clinical, biomarker and the compound models of clinical and biomarker were constructed. Kaplan-Meier method was used to plot the survival curves of different groups and compare their differences. Receiver Operating characteristics (ROC) curves were used to compare the area under the curve for CHE levels and other nutritional or prognostic indicators to identify composite end-point events.Results:During a follow-up period of 350(100,683) days, 158 patients reached the composite end points. In the multivariable Cox analysis, cholinesterase level was significantly associated with the composite end points after adjustment for major confounders. Cox proportional risk analysis or time-dependent Cox regression model showed that CHE level was significantly associated with the composite end points, all-cause mortality and cardiovascular mortality in both clinical, biomarker and composite models (all P< 0.05). A Kaplan–Meier analysis revealed that patients with low cholinesterase levels had significantly greater risk of reaching the composite end points than those with middle or high cholinesterase levels (78.1% vs 66.7% vs. 46.7%, P<0.001); Cholinesterase level showed the largest area under the receiver operating characteristic curve (AUROC) of 0.736 (95% CI, 0.664-0.888) for prediction of the composite end points among other nutritional indices. The AUROC of the Global Meta-Analysis Group Chronic Heart Failure (MAGGIC) Risk Score for prediction of the composite end points was increased from 0.704 to 0.762 ( P=0.038), when cholinesterase level was added. Conclusions:Cholinesterase may serve as a simple and effective prognostic marker for predicting adverse outcomes in ADHF patients.

Objective To evaluate the predictive value of functional liver imaging score(FLIS)based on preoperative gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI for post-hepatectomy liver failure(PHLF)in patients with hepatocellular carcinoma(HCC).Methods The data of HCC patients who underwent extensive hepatectomy and preoperative Gd-EOB-DTPA enhanced MRI were analyzed retrospectively.The FLIS was scored based on the three features including liver parenchyma enhancement,biliary excretion and portal vein signal enhancement in hepatobiliary phase images,and the consistency between different observers was evaluated.Logistic regression model and receiver operating characteristic(ROC)curve were used to analyze the ability of FLIS to predict the PHLF.Results PHLF occurred in 29 of 120 HCC patients(24.2%).The intraclass correlation coefficient(ICC)of FLIS evaluated by two observers was 0.944.Multivariate logistic regression analysis showed that FLIS was an independent predictor of PHLF of HCC patients[odds ratio(OR)0.520,95%confidence interval(CI)0.355-0.726;P<0.001].The area under the curve(AUC)of FLIS for predicting the PHLF was 0.709,the optimal diagnostic threshold was 4,and the corresponding sensitivity and specificity were 78.0%and 58.6%.Conclusion Preoperative FLIS can predict the PHLF of HCC patients,which may help to make more accurate treatment plans for HCC patients.

Objective:To evaluate the effects of different types of psychological interventions on the fear of cancer recurrence through a network Meta-analysis.Methods:Randomized controlled trials on the effects of different types of psychological interventions on the fear of cancer recurrence were retrieved from PubMed, PsycINFO, Web of Science, The Cochrane Library, Embase, EBSCO, China Biomedical Literature Database, CNKI, Wanfang Database and Vip Database. The retrieval period was from the establishment of the database to December, 31 2022. Two researchers conducted literature screening, extraction and quality evaluation, and used Stata14.0 software to conduct network Meta-analysis.Results:A total of 29 pieces of research involving 3 068 cancer patients and 11 psychological intervention measures. The results of network Meta-analysis showed that narrative therapy, PERMA(Positive, Engagement, Relationship, Meaning, Accomplishment) happiness theory model, acceptance and commitment therapy and cognitive behavior therapy had statistically significant differences in the intervention effect on the fear of cancer recurrence compared with conventional nursing ( SMD values were -1.93--0.83, all P<0.05); there was no significant difference among narrative therapy, PERMA happiness model, acceptance and commitment therapy and gratitude-expansion behavior theory (all P>0.05). The results of the cumulative probability map showed the best intervention was narrative therapy. Conclusions:The results of this study suggest that narrative therapy, acceptance and commitment therapy, and cognitive behavior therapy may be effective psychological intervention measures to improve the fear of cancer recurrence. However, more studies are still needed for further verification.

Objective:To understand the psychological experience of tumor radiotherapy patients after participating in acceptance and commitment therapy (ACT), and to provide reference and supplement for the development of ACT psychological intervention plans for tumor radiotherapy patients.Methods:This study was a qualitative study. Using the purposive sampling method, a total of 17 tumor radiotherapy patients treated at Shanghai Proton and Heavy Ion Center from January to March 2023 were selected as the research objects. Phenomenological research method was used to conduct semi-structured in-depth interviews with patients, and the interview data were analyzed by Colaizzi 7-step analysis method.Results:Three themes were extracted, namely, positive physical and mental experience (including improving physical symptoms, relieving negative emotions and cooperating with particle therapy), gaining personal growth (including learning flexible and varied psychological coping strategies, gaining mutual help and friendship, feeling valuable family affection and drawing a better future life) and recommendations for optimizing the ACT intervention program (including building teams according to the patients' conditions, increasing the frequency of activities, trying to experience relief exercises outdoors and increasing the continuity of the intervention program) .Conclusions:ACT can help cancer radiotherapy patients improve their physical and mental health, cope with psychological problems, so that patients can face the disease, treatment and life more positively.

Objective:To explore the effect of supportive-expressive group psychological intervention on the fear of recurrence in cancer patients receiving radiotherapy.Methods:From September 2022 to February 2023, convenience sampling was used to select 72 tumor inpatients from Shanghai Proton and Heavy Ion Center. According to the random number table method, patients were divided into an intervention group and a control group, with 36 cases in each group. The control group received routine nursing, while the intervention group carried out supportive-expressive group psychological intervention. The fear of recurrence, meaning in life, and perceived social support scores of two groups of patients before and after intervention were compared using the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Cancer-Meaning in Life Scale (C-MiLS), and Perceived Social Support Scale (PSSS) .Results:A total of 7 cases were lost, with 33 cases in the intervention group and 32 cases in the control group completing the study. Before intervention, there was no statistically significant difference in the general information, fear of recurrence, meaning in life, and perceived social support scores between the two groups of patients ( P>0.05). After supportive-expressive group psychological intervention, the total score of cancer recurrence fear, physical health dimension, and social family dimension scores of the intervention group were (30.42±8.31), (15.58±4.12), and (14.82±4.83), respectively, which were lower than the control group's (36.19±5.64), (18.84±3.48), and (17.09±3.27), and the differences were statistically significant ( t=-3.260, -3.446, and -2.216; P<0.05). After intervention, the total score of the intervention group's meaning in life was (63.42±6.37), which was higher than the control group's (54.91±6.53), and the difference was statistically significant ( t=5.325, P<0.05). After intervention, the perceived social support score of the intervention group was (67.64±7.93), which was higher than the control group's (62.38±10.25), and the difference was statistically significant ( t=2.318, P<0.05). After intervention, the level of fear of recurrence in the intervention group was lower than that before intervention, and the level of meaning in life and perceived social support were higher than those before intervention, with statistical differences ( P<0.05) . Conclusions:Support-expressive group psychological intervention can help cancer patients deal with survival, emotional, and interpersonal issues they face, reduce their fear of recurrence, improve their meaning in life, and perceived social support.

Objective:To investigate the efficacy and safety of combining venetoclax (VEN) with hypomethylated drugs (HMA) in the treatment of higher-risk (IPSS-R score >3.5) myelodysplastic syndromes (MDS) .Methods:From March 2021 to December 2022, forty-five MDS patients with intermediate and high risk were treated with VEN in combination with HMAs. Clinical data were collected and analyzed retrospectively, including gender, age, MDS subtype, IPSS-R score, treatment regimen, and efficacy, etc. Kaplan-Meier method and Cox regression model were used to analyze univariate and multivariate of survival prognosis.Results:①Forty-five patients with MDS, including ninety-one percent were classified as high or very high risk. According to the 2023 consensus proposal for revised International Working Group response criteria for higher-risk MDS, the overall response rate (ORR) was 62.2% (28/45), with the complete response rate (CR) was 33.3% (15/45). For twenty-five na?ve MDS, the ORR was 68% (17/25) and the CR rate was 32% (8/25). In nonfirst-line patients, the ORR and CR were 55% (11/20) and 35% (7/20) respectively. The median cycle to best response was 1 (1-4). ②With a median followup of 189 days, the median overall survival (OS) time was 499 (95% confidence interval, 287-711) days, and most patients died from disease progression. Responders had a significantly better median OS time than nonresponders (499 days vs 228 days, P<0.001). Multifactor analysis revealed that IPSS-R score and response to treatment were independent prognostic factors for OS; the presence of SETBP1 gene mutations was associated with a longer hospital stay (51.5 days vs 27 days, P=0.017) . Conclusions:There is clinical benefit of venetoclax in combination with hypomethylated agents in patients with higher-risk MDS, but adverse events such as severe hypocytopenia during treatment should be avoided.
