OBJECTIVE To introduce the development of an intelligent prescription review decision-support system for anti-tumor drugs and assess its clinical application outcomes. METHODS Relevant data sources， including national and local pharmaceutical administration policies， clinical practice guidelines/consensus， hospital information systems data， and genetic testing results， were integrated. Adhering to the principles of structure， standardization and dynamic updating， a knowledge base covering chemotherapeutic， targeted and immunotherapeutic agents was constructed using a dual-dimensional modeling approach that combined “drug attributes” and “clinical contexts”. This knowledge base was then embedded into the hospital’s electronic medical order system to establish the prescription review decision-support system. The application and performance of the system were evaluated at Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. RESULTS A knowledge base containing 18 318 prescription review rules for anti-tumor drugs was constructed， and a closed-loop prescription review system was successfully established， encompassing pre-prescription real-time intervention， in-process interactive review， and post-prescription evaluation and analysis. From 2021 to 2024， the system generated a total of 57 879 alerts for prescriptions of five typical categories of anti-tumor drugs. For platinum-containing prescriptions， 22 577 alerts were generated， with Cisplatin for injection （lyophilized） being the most frequently alerted drug （13 445 alerts）， and “ototoxicity risk due to combined use” alerts remained high （7 682 alerts）. For methotrexate-containing prescriptions， 3 721 alerts were recorded， primarily related to “precaution-related issues” （76.4%， 2 843/3 721）. For doxorubicin-containing prescriptions， 17 301 alerts were triggered， primarily related to “dosage and administration” （14 315 alerts）. For human epidermal growth factor receptor 2-targeted agents-containing prescriptions， 1 007 alerts were issued， mostly related to “reimbursement restrictions” （956 alerts）. For programmed death-1/programmed death-ligand 1 inhibitors-containing prescriptions， the alerts increased year by year， totaling 13 273 alerts， primarily related to “inappropriate indication” （9 118 alerts）. Over the 4 years， the physician response rates to system alerts were 21.4%， 27.1%， 33.5% and 51.6%， respectively. CONCLUSIONS An intelligent decision-support system for anti-tumor drug prescription review， encompassing a closed-loop process of “real-time pre-event intervention， interactive in-event prescription review， post-event evaluation and analysis”， has been successfully constructed and implemented throughout the entire workflow. There is a discernible trend in this hospital， where the focus on monitoring anti-tumor drugs is shifting towards immunotherapy drugs. Additionally， the acceptance rate of physicians regarding prescription review opinions has been steadily increasing year by year.

Objective To explore the effectiveness of the cumulative sum (CUSUM) and the exponentially weighted moving average (EWMA) for early warning of influenza epidemic using two datasets of reported influenza cases and influenza-like illness (ILI) cases. Methods Using the reported cases of influenza and ILI in Daxing District, Beijing, from week 23 of 2018 to week 22 of 2024 as data sets, the CUSUM and EWMA models were established, respectively. The positive rate of influenza etiology was used as the ^“gold standard^”, and the Youden index was used as the evaluation index to compare the early warning effect of the two models under different data sets and different parameters. Results In CUSUM, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.751 and 0.635, respectively. In EWMA, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.544 and 0.464, respectively. The optimal EWMA and CUSUM models could both issue early warning signals in advance of the ^“gold standard^”. Conclusion In the influenza epidemic early warning in Daxing District, Beijing, the CUSUM model established with the reported cases of influenza can achieve good early warning effects, but the model parameters need to be dynamically adjusted according to the local epidemic characteristics.

Objective To analyze the direct economic burden caused by surgical site infection(SSI)in orthopedics and joint surgery,and provide evidence-based support for intervention measures.Methods 3 348 hospitalized pa-tients in the department of orthopedics and joint surgery of a hospital from July 2021 to July 2023 were selected.They were divided into an infection group and a control group based on whether they had SSI.The propensity score matching(PSM)method was adopted to match the two groups of patients in a 1∶1 ratio.The length of hospital stay and various hospitalization expenses between patients with different types of SSI and control group were compared.Results Among 3 348 hospitalized patients,259 had SSI,with an incidence of 7.74％.Superficial incisional wound infection had the highest number of patients(n=177,68.34％),followed by deep incisional wound infection(n=65,25.10％),organ/space infection had the lowest number of patients(n=17,6.56％).After PSM matching,257 pairs were successfully matched,with a matching rate of 99.23％.Infection group extended length of hospital stay by 18 days compared with the control group(P＜0.001).The total hospitalization expenses and individual hos-pitalization expenses of infection group were all higher than those of the control group(all P＜0.001).Among the various expenses,difference in drug expense was the largest,with an increase of 5 067.83 Yuan in Western medi-cine(P＜0.001)and 957.30 Yuan in antimicrobial agents(P＜0.001).Patients with different types of SSI all had longer hospital stay compared with the control group.Patients with deep incisional wound infection,superficial inci-sional wound infection,and organ/space infection had an extended hospital stay of 26,18,and 13 days,respectively(all P＜0.05).The total hospitalization expenses,Western medicine expenses,and antimicrobial agent expenses of patients with different types of SSI were all higher than those of the control group(all P＜0.05).Conclusion The occurrence of postoperative SSI in patients in the department of orthopedics and joint surgery can prolong the length of hospital stay,resulting in huge economic losses for the patient and the hospital.Effective control of healthcare-associated infection is of great significance for optimizing medical resources,improving medical quality,and ensuring patient safety.

Objective:To compare the short- and long-term outcomes of robotic versus laparoscopic gastrectomy in patients with locally advanced gastric cancer after neoadjuvant chemotherapy.Methods:Data from 321 patients with locally advanced gastric cancer undergoing neoadjuvant chemotherapy followed by robotic ( n=109) and laparoscopic ( n=212) radical gastrectomy at our center between May 2017 and Sep 2022 was collected. After 1∶1 propensity score matching, 106 patients from each group were included in the final analysis to compare short-term clinical outcomes and long-term prognostic indicators. Results:The robotic group had a significantly lower overall complication rate (13.2% vs. 28.3%, χ2=6.453, P=0.007) and surgery-related complication rate (8.5% vs. 17.9%, χ2=3.333, P=0.043) than the laparoscopic group. The robotic group also retrieved more total lymph nodes (35.3±4.9 vs. 31.4±6.3, t=4.863, P<0.001) and supra-pancreatic lymph nodes (13.1±3.4 vs. 10.1±2.1, t=5.258, P<0.001). Additionally, the robotic group had a shorter operative time [(218±47) min vs. (267±71) min, t=-6.001, P<0.001], less intraoperative blood loss [(47±12) ml vs. (71±17) ml, t=-5.424, P<0.001], and faster postoperative recovery. The 3-year recurrence-free survival rate was significantly higher in the robotic group compared to the laparoscopic group (75.5% vs. 62.3%, P=0.017). Conclusion:Compared with laparoscopic gastrectomy, robotic gastrectomy allows for a more lymph nodes harvest, significantly reduces intraoperative blood loss and complication rates and significantly improves recurrence-free survival.

Purpose: Postoperative delirium (POD) is a frequent acute cognitive disorder that occurs after surgery. Enhanced recovery after surgery (ERAS) has been suggested to decrease its incidence. Due to the lack of conclusive evidence on the topic, we conducted a meta-analysis to investigate the potential impact of ERAS on POD. Methods: We included randomized controlled trials involving adult patients undergoing elective surgery. The ERAS group received management based on ERAS principles during the perioperative period, while the control group implemented traditional management strategies. The major evaluation indicators included the incidence of POD, the timing of its first occurrence, and the duration of POD. The secondary evaluation indicators were the content of Mini-Mental State Examination (MMSE) scores, the time to first ambulation, total complication rates, and length of hospital stay. Results: The results indicated that ERAS significantly reduced the overall incidence of POD (relative risk [RR] = 0.38, P <0.00001) and the incidence of delirium on the first and second postoperative days (RR = 0.20, P = 0.03; RR = 0.21, P = 0.01).It also delayed the first occurrence of POD (mean difference [MD] = –1.5, P < 0.0001), reduced its duration (MD = –2.15, P = 0.005), improved MMSE scores (MD = 1.95, P < 0.00001), sped up ambulation (MD = –1.53, P < 0.00001), decreased total complication rates (RR = 0.21, P = 0.0003), and shortened hospital stays (MD = –4.61, P < 0.00001). Conclusion In conclusion, ERAS significantly reduces POD and related complications while facilitating rapid recovery in surgical patients.

This study aims to investigate the anti-inflammatory and anti-apoptotic effects of total flavonoids of hawthorn leaves(TFHL)on lipopolysaccharide(LPS)-induced inflammatory injury in rat intestinal epithelial(IEC-6)cells,as well as the underlying mechanisms.An in vitro inflam-mation model was first established by treating IEC-6 cells with lipopolysaccharide(LPS).IEC-6 cells were then incubated with three concentrations of TFHL for 24 h prior to a further 24 h LPS treatment.RT-qPCR was used to quantify mRNA levels of the inflammatory genes COX-2 and iN-OS,while Western blotting was used to assess protein levels of the apoptotic markers Bax,cleaved Caspase-3,Bcl-2,and the JNK/p-JNK signaling pathway.Finally,cells were pretreated with TFHL and/or the JNK inhibitor SP600125 for 24 h before LPS exposure for 24 h,in order to evaluate the combined effects of TFHL and SP600125 on LPS-induced inflammatory cytokine expression and apoptotic protein levels in IEC-6 cells.The results showed that,compared with the LPS group,the mRNA level of COX-2 and iNOS in the 2.5,5.0,10.0 mg/L TFHL group and the Bax and Caspase-3 protein levels decreased significantly(P＜0.01),and the Bcl-2 protein level was significantly higher(P＜0.01),p-JNK protein level and p-JNK/JNK ratio decreased significantly(P＜0.01);compared with the LPS group,the COX-2 and iNOS mRNA levels of the TFHL+LPS group de-creased significantly(P＜0.01),Bax,and Caspase-3 protein levels decreased significantly(P＜0.01),and the level of Bcl-2 protein increased significantly(P＜0.05);compared with the LPS group,the COX-2 and iNOS mRNA levels of the TFHL+SP600125 group decreased significantly(P＜0.01),Bax and Caspase-3 protein levels decreased significantly(P＜0.01),and Bcl-2 protein level increased significantly(P＜0.01).These findings indicate that TFHL exerts anti-inflammato-ry and anti-apoptotic effects in LPS-challenged IEC-6 cells by inhibiting the JNK signaling path-way.

Objective To investigate the therapeutic mechanism of Wendan Decoction for phlegm syndrome in rats with metabolic syndrome(MS).Methods Forty Wistar rats were randomly divided into normal control group(n=8)and 3 phlegm syndrome model groups(induced by high-fat,high-sugar,and high-salt feeding and a single-dose intraperitoneal STZ injection;n=24)treated with daily gavage of saline,Wendan Decoction(3.6 g/kg),or metformin(0.1 g/kg)for 4 weeks.General conditions and glucose and lipid metabolism parameters of the rats were monitored,and serum LPS,liver histopathology,hepatic expressions of FXR,CYP7A1 and FGFR4 and ileal expressions of FXR and FGF15 were examined.Gut microbiota structure was analyzed using 16S rDNA sequencing,and serum bile acids were quantified with UHPLC-MS/MS.Results The rat models of phlegm syndrome exhibited severe hepatic steatosis and necrosis,increased body weight,abdominal circumference,Lee's index,FBG,FINS,HOMA-IR,TG,TC,LDL and LPS,and decreased HDL level.The abundance of Bacteroidetes,Megamonas,and Bacteroides in gut microbiota increased while Firmicutes,Lachnospiraceae_NK4A136_group,isohyodeoxycholic acid,and glycohyodeoxycholic acid decreased significantly;hepatic FXR and FGFR4 expressions and ileal FXR and FGF15 expressions decreased while hepatic CYP7A1 expression increased significantly in the rat models.Treatment with Wendan Decoction effectively alleviated hepatic pathology,reduced body weight and abdominal circumference,improved glucose and lipid metabolic profiles and gut microbiota structure,and reversed the changes in hepatic and ileal protein expressions.Correlation analysis revealed that Firmicutes and Lachnospiraceae_NK4A136_group were positively correlated while Bacteroidetes,Megamonas and Bacteroides were negative correlated with the levels of isohyodeoxycholic acid and hyodeoxycholic acid.Conclusion Wendan Decoction can significantly improve metabolic profiles in rats with phlegm syndrome of MS possibly by regulating the intestinal flora-bile acid axis to modulate the intestinal flora structure and maintain bile acid homeostasis via the FXR signaling pathway.

Objective: To explore the effects of Cldn14 gene knockout on renal metabolism and stone formation in rats，so as to provide reference for research in the field of urinary calium metabolism and stone formation. Methods: Cldn14 gene knockout homozygous rats and wild-type rats of the same age were randomly divided into 4 groups：wild-type control (WC) group，wild-type ethylene glycol (WE) group，gene knockout control (KC) group and gene knockout ethylene glycol (KE) group，with 10 rats in each group.The WE and KE groups were induced with ethylene glycol + ammonium chloride to form kidney stones，while the WC and KC groups received normal saline gavage.After 4 weeks of standard maintenance feeding，the urine samples were collected to detect the venous blood.The kidneys were collected for HE，Pizzolatto's staining and transmission electron microscopy.The protein in renal tissues was extracted to detect the expressions of Claudin16 and Claudin19. Results: Crystal deposition was observed in the renal tubular lumen of the WE and the KE groups，and more crystals were detected in the KE group.The WE group had a large number of intracytoplasmic black crystalline inclusions observed in renal tubular epithelial cells under transmission electron microscope，followed by the KE and KC groups.Compared with WC and WE groups，KC and KE groups had significantly decreased serum calcium and magnesium levels but significantly increased urinary calcium level.In addition，the urinary calcium level was higher in the WE group than in the WC group and higher in the KE group than in the KC group.The KE group had lower level of Claudin16，but there was no significant difference in the level of Claudin19 among the 4 groups(P>0.05). Conclusion: Knockout of Cldn14 gene alone cannot effectively reduce urinary calcium excretion or reduce the risk of stone formation in rats，which may be related to the decrease of Claudin16 level.

Gallbladder-duodenal fistula,a severe complication of cholecystitis caused by gallstones,is clinically rare.Its clinical presentation lacks specificity,and conventional preoperative imaging often fails to establish a definitive diagnosis.This report describes a case where a gallbladder-duodenal fistula was diagnosed using oral microbubble ultrasound contrast agent for gastric-duodenal contrast-enhanced ultrasound,providing a novel approach for diagnosing this condition.

Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.
