This article reports the diagnosis and treatment process of a 65-year-old male patient diagnosed with xanthoma dissseminatum. The patient sought medical attention due to reddish brown patchy rashes on the skin of the arms, knees and abdomen. The results of positron emission tomography and computed tomography (PET/CT) suggested that non-Langerhans cell histiocytosis might involve multiple blood vessels, the skin of the posterior neck and right forearm, multiple soft tissues, the descending duodenum and possibly the spine. Biopsy on skin of right arm showed non-Langerhans cell proliferative changes, with a pathological diagnosis of xanthoma dissseminatum. The rash improved after 6 cycles of monotherapy with cladribine. Follow-up PET/CT results indicated that multiple foci of abnormally increased glucose metabolism in the skin, joints, and soft tissues had decreased compared to previous examinations, suggesting disease remission. After stopping medication for 9 months, the patient underwent PET/CT reexamination, which showed new bone lesions. Bone marrow puncture was performed which suggested xanthoma dissseminatum involvement. Subsequently, the patient received chidamide combined with cladribine. By January 2025, the third cycle of chemotherapy had been completed. The patient is still under follow-up.

Objective To investigate the effects of dapagliflozin on inflammatory factors and prognosis in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI). Methods In a randomized, double-blind trial, 146 patients with T2DM and AMI (within 7 days of onset) were divided into dapagliflozin (dapagliflozin 10 mg/d combining AMI standard therapy) and control (AMI standard therapy) groups, and were followed up for 12 months. Serum levels of interleukin-1β (IL-1β), IL-6, high-sensitivity C reactive protein (hs-CRP) at baseline, 1, 3, 6, and 12 months, and left ventricular ejection fraction (LVEF), brain natriuretic peptide (BNP), and major adverse cardiovascular events (MACE) rate at 12 months were compared between the two groups. Kaplan-Meier curves were used to analyze the cumulative incidences of MACE in the two groups. Results Three patients were withdrawn or dropped out. At 12 months, IL-1β, IL-6, and hs-CRP levels were significantly lower in dapagliflozin group (n＝71) than those in control group (n＝72, P＜0.01), approaching normal levels. Compared with the control group, LVEF was higher (P＜0.01), BNP was lower (P＜0.01), MACE incidence was lower (P＝0.047) in dapagliflozin group at 12 months. Generalized linear mixed models showed significant group-time interactions in IL-1β, IL-6, and hs-CRP (P＜0.001), and these factors declined faster in the dapagliflozin group. Kaplan-Meier curve showed the cumulative incidences of MACE and heart failure were lower in dapagliflozin group than those in non-dapagliflozin group (P＜0.05). Conclusions For patients with T2DM patients and AMI, dapagliflozin has good anti-inflammatory and cardioprotective effects.

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.

Objective:To explore the prognosis after radical resection for stage Ⅰ gastric cancer and the application value of adjuvant chemotherapy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 3 353 patients with stage Ⅰ gastric cancer who were admitted to Fudan University Shanghai Cancer Center from January 2000 to December 2022 were collected. There were 2 369 males and 984 females, aged 60(range, 21-91) years. All patients underwent radical R 0 resection. Observation indicators: (1) clinicopathological characteristics of patients; (2) influencing factors for postoperative prognosis of patients; (3) prognostic analysis of patients; (4) construction and validation of a predictive model for the efficacy of postoperative adjuvant chemotherapy. Comparison of count data between groups was conducted using the chi-square test. Univariate and multivariate analyses were performed using the Cox proportional hazards regression model. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and the Log-rank test was used for survival analysis. Based on the multivariate analysis result, a nomogram prediction model was constructed to predict survival benefit. Results:(1) Clinicopatho-logical characteristics of patients. The highly, moderately, and poorly differentiated tumors were observed in 16, 234, 396 cases of 646 patients aged <50 years and 279, 1 617, 811 cases of 2 707 pati-ents aged ≥50 years, respectively, showing a significant difference in degree of tumor differentiation between them ( P<0.05). For 297 patients in stage T1N1M0, cases aged <50 years and ≥50 years were 71 and 226, cases of males and females were 184 and 113, cases with negative and positive vascular invasion were 37 and 260, cases with negative and positive nerve invasion were 275 and 22, cases without and with postoperative adjuvant chemotherapy were 222 and 75, respectively. The above indicators for 678 patients in stage T2N0M0 105, 573, 533, 145, 517, 161, 526, 152, 563, 115, respectively. There were significant differences in the above indicators between the two groups ( P<0.05). (2) Influencing factors for postoperative prognosis of patients. Results of multivariate analysis showed that age ≥50 years, stage T2, moderately differentiated tumor, the number of lymph nodes dissected <16, positive vascular invasion, carcinoembryonic antigen (CEA) ≥5 μg/L, and CA19-9 ≥37 U/mL were independent risk factors for disease-free survival (DFS) after surgery for stage Ⅰ gastric cancer ( hazard ratio=4.600, 1.555, 1.835, 1.362, 1.451, 1.571, 2.134, 95% confidence interval as 2.806-7.541, 1.205-2.006, 1.016-3.314, 1.059-1.753, 1.057-1.993, 1.100-2.243, 1.257-3.625, P<0.05). Age ≥50 years, stage T2, the number of lymph nodes dissected <16, positive vascular invasion, CEA ≥5 μg/L, and CA19-9 ≥37 U/mL were independent risk factors for overall survival (OS) after surgery for stage Ⅰ gastric cancer ( hazard ratio=5.208, 1.597, 1.373, 1.520, 1.464, 2.356, 95% confidence interval as 3.028-8.955, 1.231-2.072, 1.060-1.777, 1.099-2.104, 1.004-2.134, 1.385-4.009, P<0.05). Postoperative adjuvant chemotherapy was an independent protective factor for both DFS and OS after surgery for stage I gastric cancer ( hazard ratio=0.361 0.297, 95% confidence interval as 0.177-0.736, 0.131-0.674, P<0.05). (3) Prognostic analysis of patients. According to the results of multi-variate analysis, among 3 353 patients, there were significant differences in 5-year DFS rate and 10-year OS rate between patients aged <50 years and ≥50 years ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate among patients in TNM stage ⅠA and ⅠB ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate among patients in stage T1N0M0, T1N1M0, T2N0M0 ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate among patients with the highly, moderately, and poorly differentiated tumors ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate among patients with the number of lymph lodes dissected <16 and ≥16 ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate between patients with negative and positive vascular invasion ( P<0.05). There were significant differences in 5-year DFS rate and 10-year OS rate between patients with and without postoperative adjuvant chemotherapy ( P<0.05), among patients in stage T1N0M0, T1N1M0, T2N0M0 who received no postoperative adjuvant chemotherapy ( P<0.05). For patients in stage T1N1M0, there was no significant difference in 5-year DFS rate and 10-year OS rate between patients with and without postoperative adjuvant chemotherapy ( P>0.05).Results of stratified analysis showed that for patients aged ≥ 50 years, there were significant differences in 5-year DFS rate and 10-year OS rate between patients with and without postoperative adjuvant chemotherapy ( P<0.05). For patients in stage T2N0M0, there were significant differences in 5-year DFS rate and 10-year OS rate between patients with and without postoperative adjuvant chemotherapy ( P<0.05). For patients with positive vascular invasion, there were significant differences in 5-year DFS rate and 10-year OS rate between patients with and without postoperative adjuvant chemotherapy ( P<0.05). (4) Construction and validation of a predictive model for the efficacy of adjuvant chemotherapy. A nomogram predictive model was constructed based on the multivariate analysis results of OS and used for calculating net benefits and distribution. Among the 3 096 patients without postoperative adjuvant chemotherapy, 1 009 cases had a predicted net benefit of >5%-10%, and 250 patients had a predicted net benefit >10%. The predicted survival analysis further verified that the predicted benefit of adjuvant chemotherapy was consistent with the prognosis of patients. Conclusions:Patients with age ≥50 years, stage T2 tumors, moderately differentiated tumor, the number of lymph nodes dissected <16, positive vascular invasion have worse survival prognosis postoperative. Postoperative adjuvant chemotherapy provides better prognosis in high-risk patients. Patients in stage T1N1M0 have lower recurrence and survival risks, of whom with 1 metastatic lymph node is more suitable for follow-up rather than postoperative adjuvant chemotherapy.

Objective To propose a clinical typing method for lumbar degenerative disease(LDD),including the diagnostic criteria for each type and the corresponding surgical treatment strategies.Methods A total of 245 LDD patients who were admitted to Department of Orthopaedics,The Second Affiliated Hospital of Naval Medical University from Jun.2017 to May 2022 were enrolled and assigned to nerve root type(42 cases),disc herniation type(73 cases),spinal stenosis type(61 cases),spondylolisthesis type(29 cases),and local type(40 cases)according to our diagnostic criteria of clinical typing.Treatment outcomes of various groups were compared and the reliability of the typing method was assessed using consistency test.Results A total of 205 cases received surgical treatment and 40 cases received non-surgical treatment.The surgical approach was modified transforaminal lumbar interbody fusion.The patients were followed up for(20.37±6.13)months.According to Nakai's evaluation criteria,the clinical effect was excellent in 146(59.59％)cases,good in 89(36.33％)cases,fair in 8(3.27％)cases,and poor in 2(0.82％)cases,with an excellent and good rate of 95.92％.There were no significant differences in the treatment effects among different types of LDD(P＞0.05).The results of clinical consistency evaluation confirmed that the typing method had good consistency both within observers and between observers.Conclusion This clinical typing method can help to further understand the pathogenesis of LDD,improve the accuracy of diagnosis and optimize the treatment plan.

A 42-year-old male patient developed mild allergic symptoms after the use of cisatracurium besylate in laparoscopic left renal tumor resection,which was relieved by symptomatic treatment.When the drug was added again intraoperatively,the patient's blood pressure decreased sharply from 120/71 mmHg to 50/30 mmHg,and the airway resistance increased from 16 cmH2O to 38 cmH2O,and the patient developed typical signs of anaphylactic shock.After immediate intravenous injection of epinephrine,calcium chloride and other drugs,the patient's blood pressure rose to 95/57 mmHg,airway resistance decreased to 20 cmH2O,and vital signs tended to be stable.The Naranjo's Assessment Scale was used to evaluate and analyze the correlation of suspected drugs.The score was 9 points,indicating that the association between anaphylactic shock and cisatracurium besylate in this patient was judged to be"definitely related".This article suggests that cisatracurium besylate carries an allergic risk and should be used with caution,and the monitoring of vital signs and allergic reactions should be strengthened for early identification and timely treatment to ensure the safety of patients during the perioperative period.

This study aims to innovate a homogeneous outpatient service management system across multiple hospital campuses to enhance service quality.Based on the practical experience of a tertiary general hospital in Guangdong Province and in accordance with the"Interim Regulations on Outpatient Quality Management in Healthcare Institutions,"we constructed a"6+1"homogeneous outpatient service management system.This system includes:① a multi-stakeholder co-governance outpa-tient management system,②a vertical and cross-hierarchical management network,③ a democratic-centralized clinical coordina-tion strategy,④ a guidance-encouragement performance evaluation standard,⑤a collaborative dynamic supervision mechanism,⑥a spiral retrospective evaluation and improvement method,and ⑦ an integrated outpatient diagnosis and treatment system.Af-ter over two years of implementation,the hospital's outpatient volume has grown by an average of over 15％annually,patient waiting time after appointment has been reduced to 20 minutes,and patient satisfaction in the tertiary public hospital performance evaluation achieved full marks.The electronic medical record system functionality reached Level 6,significantly improving healthcare service efficiency and quality while enhancing homogeneous management across campuses.

Chronic heart failure(CHF)is a common end-stage manifestation of cardiovascular disease,and the"spleen-small intestine-heart"axis is its important mechanism.Current studies have shown that the"spleen"in TCM and mitochondria function are similar,and the physiological dysfunction of the"small intestine"is also closely related to intestinal bacterial dysbiosis,and the pathology of the spleen and the small intestine will be transmitted to the heart to accelerate the occurrence and development of CHF.Based on the relevant theory of spleen-small intestine-heart,this article described the correlation between abnormal mitochondrial energy metabolism and imbalance of intestinal flora and CHF from the aspects of the spleen,small intestine and heart,and believed that the essence of CHF is a pathological condition formed by mitochondrial energy metabolism crisis and intestinal microecological disorders,which could provide theoretical references for the TCM prevention and treatment of CHF.

Objective This study aims to conduct a comprehensive analysis of the domestic and international standards for prefilled syringes to advance the scientific and international alignment of China's PFS standard system.Methods A thorough review of the framework,scope,and quality control key points of the 2015 national pharmaceutical packaging material standards(abbreviated as YBB standards),the ISO 11040 international standard system and the United States Pharmacopeia standard system was conducted.Comparative analysis was employed to reveal the similarities and differences among the three,thereby uncovering the unique characteristics of each.Results The YBB standards emphasize quality control for prefilled syringes,offering clear and operational guidelines that provide companies with precise directives for production and testing.However,the scope of these standards is relatively limited.ISO standards apply to a wide range of products,featuring comprehensive coverage and a degree of flexibility.They emphasize the universality of products and compatibility with other international standards,which facilitates global production and trade.USP includes several chapters related to prefilled syringes but lacks a certain level of specificity and systematic approach.Conclusion By thoroughly studying and drawing upon the quality control philosophies,standard frameworks,and key control points of prefilled syringes from both domestic and international standards,we aim to provide valuable references for the development of a robust prefilled syringe standard system within the Chinese Pharmacopoeia.

Objective To explore the correlation between serum hypoxia-inducible factor-1α(HIF-1α)levels and cerebral microbleeds(CMBs)and cognitive impairment and to assess the predictive value of HIF-1α for CSVD-related cognitive impairment.Methods A total of 104 patients with CSVD who attended the Department of Neurology,First Affiliated Hospital of Xinxiang Medical University from June 2022 to November 2023 were enrolled.All enrolled patients were subjected to basic statistics,cranial nuclear magnetic resonance examination,cognitive function assessment,and serum HIF-1α test,and the number and location of CMBs were counted.Based on the above data the enrolled patients were grouped.The correlation between HIF-1α and cognitive function and CMBs was studied the influencing factors of CMBs and cognitive impairment were analyzed,and the predictive value of HIF-1α on the occurrence of cognitive impairment was evaluated.Results There were statistically significant differences in HIF-1α levels and cognitive function among different CMBs groups.Serum HIF-1α levels were significantly negatively correlated with overall cognitive function,visuospatial and executive function,attention,and delayed recall,and serum HIF-1α was positively correlated with the number of CMBs.HIF-1α may be a risk factor for CMBs and cognitive impairment associated with CSVD,and serum HIF-1α has potential in predict the cognitive impairment caused by CSVD.Conclusion Serum levels of HIF-1α were associated with the number of CMB and CSVD-related cognitive impairment,and serum levels of HIF-1α may have a predictive value for CSVD-related cognitive impairment.
