In this report,we described a case of a clinical practice,in which the clinical pharmacists was involved in the treatment of a soft tissue sarcoma patient,who was diagnosed with mental disorders induced by regorafenib.The patient was complicated with hypoproteinemia,hepatic insufficiency,leukoencephalopathy and other diseases.Before the treatment,the patient's mental was normal.After continuous administration of regorafenib(40 mg,po,qd)for 5 days,the patient has a sudden loss of consciousness.Clinical pharmacists excluded the possibility of mental disorders caused by tumor brain metastases,exacerbation of leucoencephalopathy or hepatic encephalopathy and the drugs used together.They determined that mental disorders were likely to be related to the use of regorafenib through the association evaluation of adverse reactions.It was considered to be an adverse reaction induced by regorafenib.Therefore,regorafenib treatment was temporarily suspended and symptomatic treatment was given.After 5 days,the patient's mental state improved.In addition,clinical pharmacists monitored the patient for symptomatic treatment,and provided appropriate antitumor drug treatment recommendations based on evidence-based evidence.This case suggests that the clinical use of regorafenib should be vigilant against mental disorders adverse reactions,do a good job of pharmaceutical care,and timely drug analysis and symptomatic treatment after adverse reactions.

Under the background of high-intensity fattening,probiotics have gradually become wide-ly used feed additives.It can inhibit the proliferation of pathogenic bacteria,maintain the microeco-logical balance in the digestive tract,and improve the host immune function.In order to screen lac-tic acid bacteria strains with potential probiotic effects,23 acid-producing strains were isolated from rumen fluid of healthy Duolang sheep by CaCO3-MRS solid medium.Safe strains were re-screened through primary screening and hemolysis tests.Acid tolerance tests and bile salt tests were used to screen the strains that were relatively adapted to the rumen environment.The survival rate of the strain M2 was 93.80％under pH3.0 and 59.72％under bile salt concentration of 0.30％and the survival rate is higher than other strains under high temperature conditions.Subsequently,morphological observation,molecular biological identification,testing of pathogen antagonism,antibiotic tolerance analysis,growth characteristics detection and other methods were used to fur-ther explore the characteristics of the strain.The results showed that the strain to be tested was Gram-positive bacillus.After 16S rRNA gene sequence comparison,the strain was identified as Lactobac illus salivus,which could be used as a candidate strain to develop probiotics.The research results laid a foundation for its application in Duolang sheep breeding.

Objective To investigate the correlation between thyroid function,neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR)and diabetic ketoacidosis(DKA).Methods A total of 272 diabetic patients admitted to the Department of Endocrinology,Anhui No.2 Provincial People's Hospital were enrolled in this study from January 2021 to March 2024 and divided into DKA group(n=74),diabetic ketosis group(DK group,n=100)and simple DM group(n=98)according to their disease conditions.Serum free triiodothyronine(FT3),free tetraiodothyronine(FT4),thyroid stimulating hormone(TSH),FPG,HbA1c,anion gap(AG),white blood cells(WBC),neutrophils(N),platelets(PLT)and lymphocytes(L)were detected in each group,and NLR and PLR were calculated.The influence factors of DKA were analyzed by logistic regression,and the diagnostic value of FT3,NLR and PLR in DKA was evaluated by receiver operating characteristic(ROC)curve.Results Hospitalization days,FPG,HbA1c,incidence of LT3S,AG,WBC,N,PLT,NLR,PLR were higher in DKA group than in DM and DK groups(P<0.05),Age,FT3,FT4,TSH,L were lower in DKA group than in DM and DK groups(P<0.05).Logistic regression analysis showed that FT3,AG,NLR and PLR were the influencing factors for DKA.ROC curve showed that the area under the curve of FT3,NLR,PLR and combined detection to predict DKA were 0.961,0.938,0.810 and 0.980,the sensitivity was 87.8%,90.5%,75.7%and 98.6%,the specificity was 95.5%,92.9%,76.3%,92.4%,and the combined detection was superior to the single detection.Conclusions FT3,NLR,PLR have a certain diagnostic value for DKA,and the combined detection of the three has a high diagnostic value,which can provide a reference for clinical diagnosis of DKA.

Objective:To identify the differentially expressed proteins that caused hippocampal damage after liver ischemia-reperfusion (I/R) in rats.Methods:Eighteen clean-grade healthy juvenile male Sprague-Dawley rats, aged 2 weeks, weighing 20-30 g, were divided into 2 groups ( n=9 each) using a random number table method: sham operation group (S group) and liver I/R group (IR group). A rat model of liver I/R injury was prepared by restoring perfusion after 1 h of liver ischemia. The rats were sacrificed after being anesthetized at day 3 of reperfusion, and the hippocampal tissue was isolated and analyzed to obtain gene expression profiles. Differentially expressed genes were identified using the R software, and further protein interaction networks were constructed through Cytoscape and Kyoto Encyclopedia Genes and Genomes pathway analysis to determine the differentially expressed proteins. Quantitative real-time polymerase chain reaction and Western blot were used for validation. Results:A total of 45 differentially expressed proteins were identified by the proteomic analysis of hippocampal tissues, including 36 significantly up-regulated proteins and 9 significantly down-regulated proteins. The proteins with significant expression related to injury were identified from the PPI network complex using the CytoHubBA plug-in cystscape: Ras-related C3 botulinum toxin substrate (RAC2), HRAS, phosphatidylinositol-3-kinase inhibitor phosphatase and tensin homologue (PTEN), and N-methyl-D-aspartate ionotropic glutamate receptor 2b (GRIN2b). The results of quantitative real-time polymerase chain reaction and Western blot showed that the expression of RAC2, HRAS, PTEN, and GRIN2b in the hippocampal tissue was significantly up-regulated in IR group compared with S group ( P<0.05). The results of Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that differentially expressed proteins were significantly enriched in the expression of PD-L1 and its checkpoint pathway, long-term potentiation, and regulation of the Wnt signaling pathway in cancer. Conclusions:The mechanism by which liver I/R induces hippocampal injury may be related to the up-regulation of the expression of RAC2, HRAS, PTEN and GRIN2b in rats.

Objective:To assess the association between diabetes mellitus and the risk of sudden cardiac death (SCD), and to identify potential contributing factors.Methods:This meta-analysis was an updated version of the original study Diabetes mellitus and the risk of sudden cardiac death： a systematic review and meta-analysis of prospective studies. The original review included all eligible case-control and cohort studies published in PubMed and Embase up to 2017 that investigated the association between diabetes and SCD risk. In this updated study, newly published studies were added, including those available in PubMed, Embase, China National Knowledge Infrastructure (CNKI), and WANFANG MED ONLINE up to December 3, 2023. Search terms included "diabetes""glucose""sudden cardiac death" "cardiac arrest" and their Chinese equivalent. The primary outcome was the risk of SCD, while factors such as country, ethnicity, skin color, follow-up duration, left ventricular ejection fraction (LVEF), baseline comorbidities, and other relevant variables were analyzed as potential influencing factors. Relative risk ( RR) was used as the summary measure. A random-effects model was used when significant heterogeneity was detected, otherwise a fixed-effects model was used. Cochran′s Q test was used for subgroup analysis to assess the influence of factors such as region, baseline diseases, LVEF, and ethnicity (based on skin color) on the outcomes. Results:A total of 32 cohort/case-control studies with a combined sample size of 3 252 954 individuals were included. The meta-analysis showed that the risk of SCD in patients with diabetes was double that of non-diabetics ( RR=2.00, 95% CI: 1.83-2.19, P<0.001). In Asian populations, the risk of SCD in diabetic patients was 1.78 times that of non-diabetic individuals ( RR=1.78, 95% CI: 1.51-2.10), 2.05 times that of in European populations ( RR=2.05, 95% CI: 1.79-2.34), and 2.12 times that of in American populations ( RR=2.12, 95% CI: 1.82-2.47), with no statistically significant heterogeneity between regions ( P=0.287). Among individuals without other baseline comorbidities, the risk of SCD was 2.12 times higher in diabetic patients than in those without diabetes ( RR=2.12, 95% CI: 1.89-2.38). In patients with baseline coronary heart disease, the risk was 1.75 times that of non-diabetics ( RR=1.75, 95% CI: 1.45-2.11). In those with baseline heart failure, the risk was 1.92 times that of non-diabetics ( RR=1.92, 95% CI: 1.51-2.43). In patients with baseline atrial fibrillation, the risk was 4.00 times that of non-diabetic individuals ( RR=4.00, 95% CI: 1.38-11.56). In patients undergoing hemodialysis due to renal failure, the risk was 1.76 times that of non-diabetic individuals ( RR=1.76, 95% CI: 1.25-2.48), with no statistically significant heterogeneity between groups ( P=0.262). In cardiac patients with LVEF>50%, the risk of SCD in diabetic patients was 2.08 times that of non-diabetic individuals ( RR=2.08, 95% CI: 1.57-2.75), and in those with LVEF<50%, the risk was 1.69 times that of non-diabetic individuals ( RR=1.69, 95% CI: 1.30-2.18), with no statistically significant heterogeneity between groups ( P=0.277). In yellow-skinned populations, the risk of SCD in diabetic patients was 1.80 times that of healthy individuals ( RR=1.80, 95% CI: 1.73-1.87), and in white-skinned populations, it was 2.18 times that of healthy individuals ( RR=2.18, 95% CI: 1.88-2.54), with statistically significant heterogeneity between groups ( P=0.014). Conclusions:Diabetes mellitus significantly increased the risk of SCD, and this effect may be more pronounced in white-skinned populations, while region, baseline comorbidities, and LVEF had no further effect.

Objective:To investigate the impact of body mass index (BMI) on delayed extubation of patients with acute Stanford type A aortic dissection (ATAAD).Methods:A total of 400 ATAAD patients who were admitted to our hospital from October 2021 to October 2023 and underwent surgical treatment were selected as the research objects. According to BMI, they were divided into obese group (BMI≥28 kg/m 2, 119 cases) and non-obese group (BMI<28 kg/m 2, 281 cases). The differences of preoperative clinical characteristics, intraoperative and postoperative data between the two groups were compared. Starting from transferring to the ICU and ending with the first successful extubation, The risk factors of postoperative invasive mechanical ventilation time ≥ 48 h in ATAAD patients were analyzed, and the predictive efficacy of related factors for postoperative invasive mechanical ventilation time ≥ 48 h in ATAAD patients was evaluated. Results:Compared with the non-obese group, the proportion of hypertension, diabetes, admission heart rate, admission systolic blood pressure, admission diastolic blood pressure and preoperative white blood cell count in the obese group were significantly increased, and the differences were statistically significant ( P<0.05). The cardiopulmonary bypass time, aortic cross-clamp time, operation time, red blood cell transfusion volume, invasive mechanical ventilation time, secondary operation rate and total hospitalization cost in the obese group were significantly higher than those in the non-obese group, and the differences were statistically significant ( P<0.05). Univariate logistic regression analysis showed that BMI, cardiopulmonary bypass time, ascending aortic cross-clamp time, operation time, age, hypertension, and red blood cell transfusion were related factors for postoperative invasive mechanical ventilation time ≥48 h in ATAAD patients ( P<0.05). Logistic multivariate regression analysis showed that increased BMI ( OR=1.213, P<0.05) and increased age ( OR=1.020, P<0.05) were independent risk predictors of postoperative invasive mechanical ventilation time≥48 h in ATAAD patients. Receiver operating characteristic curve ( ROC) analysis showed that the area under the ROC curve ( AUC) of BMI for predicting the duration of postoperative invasive mechanical ventilation in ATAAD patients≥48 h was 0.682 ( P<0.05), and the best predictive cut-off value was 25.64 kg/m 2. Conclusion:BMI≥28kg/m 2 increases the difficulty of surgery and the duration of invasive mechanical ventilation in ATAAD patients. BMI has a high predictive value for the duration of invasive mechanical ventilation in ATAAD patients after surgery ≥48 h, and effective intervention measures can be formulated to improve the treatment effect of patients.

Objective:To investigate the effect of low density lipoprotein cholesterol (LDL-C) on the progression of retinal arteriosclerosis by using a deep learning model.Methods:A cohort study was performed.Data of 1 928 individuals who underwent the medical examination at Beijing Yijiandian Clinic between January 2016 and August 2023 were reviewed, including baseline demographics, physical examination, serological test and fundus photography.Retinal arteriosclerosis was identified using a deep learning model.Five groups were divided according to LDL-C levels, including 389 subjects in group 1 (0.64-1.90 mmol/L), 387 subjects in group 2 (1.91-2.26 mmol/L), 384 subjects in group 3 (2.27-2.57 mmol/L), 385 subjects in group 4 (2.58-2.95 mmol/L), and 383 subjects in group 5 (2.96-6.06 mmol/L).The association between LDL-C levels and progression of retinal arteriosclerosis and the dose-response relationship were analyzed by logistic regression analysis and restricted cubic spline (RCS) regression model.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Peking University People's Hospital (No.2021PHB058-001).Written informed consent was obtained from each subject.Results:The incidence of retinal arteriosclerosis progression was 22.10% (426/1 928) during the mean follow-up (66.84±6.58) months.The proportions of fundus progression in groups 1, 2, 3, 4, and 5 were 15.68%(61/389), 21.71%(84/387), 21.35%(82/384), 25.71%(99/385), and 26.11%(100/383), respectively, with statistical significant differences among them ( χ2=15.97, P=0.003).Using group 1 as a reference, LDL-C 2.58-2.95 mmol/L was an independent risk factor for progression of retinal arteriosclerosis ( OR=1.52, 95% CI: 1.04-2.22), and RCS analysis showed an " L" shaped association.The effect of LDL-C on retinal arteriosclerosis showed a threshold effect, with the risk of retinal arteriosclerosis progression increasing with increasing LDL-C when LDL-C was <2.34 mmol/L ( OR=1.97, 95% CI: 1.10-3.62), and stabilizing when LDL-C was ≥2.34 mmol/L. Conclusions:LDL-C has a threshold effect on the impact of retinal arteriosclerosis progression, and the threshold is 2.34 mmol/L.

The restoration of right ventricle dysfunction is essential to the maintenance of systemic circulation in patients after cardiac surgery.It also plays a significant part in planning surgical repair following the last stage of surgical palliation.Nevertheless,the complex geometry and wall motion of the right ventricle make it difficult to evaluate the right ventricle function with the noninvasive tools.Cardiac magnetic resonance(CMR)is the gold standard of the most commonly used technology for cardiac imaging,which is necessary to be involved in regular surveillance for patients undergoing complicated cardiac surgery.The application of new CMR technology mainly includes 4D flow hemodynamic measurement,MR1 mapping and tracking technology to evaluate the right ventricular function by detecting the myocardial injury.Echocardiography is the first-line method of postoperative assessment and appropriate for all kinds of congenital heart disease.Speckle-tracking echocardiography has been further development in recent years.Cardiac computed tomography has prominent advantages in detecting the vessels and pulmonary lesions,which is often used as an alternative to MRI.The development of artificial intelligence in image processing technology has greatly improved the diagnostic and predictive value of imaging examination.By comparing the characteristics of CMR,echocardiography and cardiac computed tomography,this paper reviews the research progress of these three imaging methods in the evaluation of the postoperative right ventricle function in congenital heart disease.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Purpose To explore the expression,mechanism and clinical significance of MCM5 in ovarian cancer.Methods The expression of MCM5 mRNA in ovarian cancer and its correlation with patients'survival were analyzed using GEO and TCGA databases.The expression of MCM5 protein in ovarian cancer was detected by immunohistochemistry of SP two-step method,and its relationship with clinicopathological characteris-tics was analyzed.With inhibition of MCM5 by siRNA in ovarian cancer cells.The effects of MCM5 on cell proliferation,migra-tion,invasion,and apoptosis were detected by CCK-8 assay,EDU,plate cloning,Transwell chamber and flow cytometry.Re-sults Immunophenotype:MCM5 does not stain in the fallopian tube epithelium(0/6),with a positivity rate of 48.3％(57/118)in ovarian cancer.The expression of MCM5 in ovarian cancer is significantly higher than in fallopian tube epithelium,showing diffuse strong expression in high-grade serous carcino-ma.MCM5 expression is strongly correlated with ER-negative status and high Ki67 proliferation index.Knocking down MCM5 expression inhibits proliferation(P＜0.05),clonogenicity(P＜0.05),invasion and migration(P＜0.05)of ovarian cancer cells,and promotes apoptosis.Conclusion MCM5 is highly expressed in human ovarian cancer cells and tissues and is asso-ciated with poor prognosis.It is expected to become a new target for the treatment of ovarian cancer.
