OBJECTIVE To analyze the safety and efficacy of vonoprazan （VPZ） in the treatment of peptic ulcer （PU） and post-endoscopic submucosal dissection （ESD） ulcers， providing evidence-based pharmaceutical evidence for clinical practice and medical decision-making. METHODS Retrieved from CNKI， Wanfang， VIP， CBM， PubMed， Embase， Web of Science， and the Cochrane Library， meta-analyses/systematic reviews related to VPZ in the treatment of PU and post-ESD ulcers were collected. Two researchers independently performed literature screening， data extraction， quality assessment of included studies， and evaluation of literature overlap. By employing the umbrella review analysis， a fresh meta-analysis was conducted on all relevant raw research data when a high degree of overlap was identified among the included studies. RESULTS A total of 17 meta-analyses were included， with quality ranging from high to very low； all outcome measures involved showed a very high level of overlap in the included meta-analyses （corrected covered area： 22.22%-100%）. In the treatment of post-ESD ulcers， compared to proton pump inhibitor （PPI）， VPZ significantly improved the ulcer healing rate at 4 weeks post-ESD [RR＝1.27， 95%CI （1.03， 1.56）， Z＝2.21， P＝ 0.027] and the ulcer contraction rate post-ESD [MD＝0.08， 95%CI （0.00， 0.16）， Z＝2.09， P＝0.037]， while significantly reducing the ulcer recurrence rate in patients with a history of PU [RR＝0.49， 95%CI （0.32， 0.73）， Z＝3.49， P＝0.001]； the delayed bleeding rate in the VPZ group was significantly lower than that in the lansoprazole subgroup [RR＝0.47， 95%CI （0.25， 0.90）， Z＝2.28， P＝0.02]. In the treatment of PU， the incidence of adverse events with VPZ was significantly higher than that with PPI in the duodenal ulcer subgroup [RR＝1.13， 95%CI （1.02， 1.26）， Z＝2.38， P＝0.017]. CONCLUSIONS For post-ESD ulcers， VPZ demonstrates superior therapeutic efficacy compared to PPI and can reduce ulcer recurrence rates in patients with a history of PU. However， it does not offer advantages in terms of safety for duodenal ulcer treatment.

Objective To construct an evaluation index system for rational drug use management of key monitoring drugs,and to provide references for medical institutions.Methods The preliminary index framework was formed by researching the policies and regulations,management norms,and guiding principles related to key monitoring drugs.Two rounds of Delphi questionnaire survey were conducted with 26 experts to improve and optimize the index system.The weights of the indicators were obtained by constructing the judgment matrix by analytic hierarchy process(AHP).Results The recovery rates of the two rounds of questionnaire were both 100％,and the authority coefficient was 0.87.The key monitoring drug rational use management evaluation index system was finally constructed to include three primary indicators[ex-ante management(0.253 6),in-process management(0.503 1),and ex-post management(0.243 2)],15 secondary indicators[including prescription review(0.302 6),formulate rational drug use norms(0.133 1),supernormal early warning management(0.103 2)],and 62 tertiary indicators[inclu-ding formulate strict prescription review rules(0.152 5),pharmacists prescription intervention strength(0.085 7)and effective-ness management(0.052 5)].and the index judgment matrix passed the consistency test.Conclusion The evaluation index system for the rational drug use management of key monitoring drugs constructed can satisfy the closed loop of the supervision and management process,achieve the prior reminder,monitoring,and post-supervision,and provide references for medical institutions to ensure the refinement and standardization of the management process.

ObjectiveTo explore the target of Erzhiwan in reducing myocardial injury in ovariectomized mice through non-targeted myocardial metabolomics combined with experimental verification. MethodsOvariectomized mouse model was selected， 40 female C57BL/6 mice were randomly divided into sham operation group， model group， estrogen group（estradiol valerate， 1.3×10^-4 g·kg^-1）， Erzhiwan low and high dose groups（3.12， 9.36 g·kg^-1）， with 8 mice in each group. Each administration group was given the corresponding dose of Erzhiwan by gavage， and the sham operation group and model group were given equal volume of distilled water by gavage for 12 weeks. Echocardiography was used to detect cardiac function， hematoxylin-eosin（HE） staining was used to observe myocardial morphological changes， and enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of estrogen， N-terminal pro-brain natriuretic peptide（NT-proBNP）， hypersensitive troponin T（hs-TnT）， total cholesterol（TC）， triglyceride（TG）， low density lipoprotein cholesterol（LDL-C）， high density lipoprotein cholesterol（HDL-C）， interleukin（IL）-1β， IL-18 and tumor necrosis factor-α（TNF-α）. The non-targeted metabolomics of mouse myocardium were analyzed by ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， and the differential metabolites and corresponding metabolic pathways were obtained. The mRNA expression levels of phosphatidylinositol 3-kinase（PI3K） and protein kinase B（Akt） in mouse myocardial tissues were detected by real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the protein expression levels of PI3K， Akt， phosphorylated（p）-Akt were detected by Western blot. ResultsCompared with the sham operation group， the model group showed abnormal cardiac function， increased myocardial fiber space， cardiomyocyte atrophy， sarcoplasmic aggregation， and occasional dissolution or rupture of muscle fiber， the level of estrogen in the serum was decreased， the levels of NT-proBNP， hs-TnT， IL-1β， IL-18， TNF-α， TG， TC and LDL-C were increased， and the level of HDL-C was decreased（P<0.01）. Compared with the model group， Erzhiwan could increase the level of estrogen， improve the abnormal cardiac function， reduce the pathological injury of myocardial tissue， decrease the levels of myocardial injury markers（NT-proBNP， hs-TnT） and inflammatory factors（IL-1β， IL-18， TNF-α）， decrease the levels of TG， TC， LDL-C， and increased the level of HDL-C（P<0.01）. The results of non-targeted myocardial metabolomics showed that 31 of the 162 differential metabolites between the model group and sham operation group were significantly adjusted after administration of Erzhiwan， which were mainly glycerol phospholipid metabolites. Pathway enrichment results showed that Erzhiwan mainly affected glycerophospholipid metabolic pathway， PI3K-Akt pathway， cyclic guanosine monophosphate（cGMP）-protein kinase G（PKG） pathway and other metabolic pathways. Compared with the sham operation group， the levels of phosphatidylcholine（PC， 11 types） and phosphatidylethanolamine（PE， 5 types） in mouse myocardial tissue of the model group were increased（P<0.05， P<0.01）， and the mRNA and protein expressions of PI3K and p-Akt were decreased（P<0.05， P<0.01）. Compared with the model group， the levels of PC（11 types） and PE（5 types） were decreased（P<0.05， P<0.01） in myocardial tissue of Erzhiwan group， the mRNA and protein expressions of PI3K and p-Akt were elevated（P<0.01）. ConclusionErzhiwan can alleviate the pathological injury of myocardium in ovariectomized mice， improve the abnormal cardiac function， improve lipid metabolism disorder， and reduce the levels of myocardial injury markers and inflammatory factors， which involves a number of signaling and metabolic pathways in the heart， among which glycerophospholipid metabolism pathway and PI3K/Akt pathway may have key roles.

OBJECTIVE To explore the effect of superoxide dismutase （SOD） administration on the malignant behavior of PLC/PRF/5 liver cancer cells， and analyze the correlation between SOD and alpha-fetoprotein （AFP） expression， to provide new ideas for targeting AFP with SOD as a drug for hepatocellular carcinoma. METHODS Normal human liver cells L-02， AFP- negative human liver cancer cells HLE， and AFP-positive human liver cancer cells PLC/PRF/5 were used as experimental cells. Western blot assay and SOD activity detection kit were used to detect the expression of AFP， SOD and activity of SOD in cells before and after changing AFP expression； the effects of different concentrations of SOD [0 （control）， 0.188， 0.375， 0.75， 1.5， 3 U/mL] administration on the migration and proliferation of PLC/PRF/5 cells were detected using cell scratch assay and CCK-8 assay. The effects of SOD overexpression on the expression of malignant biological behavior-related proteins AFP and sarcoma virus protein （Src） in PLC/PRF/5 cells were detected using Western blot. RESULTS Compared with L-02 group and HLE group， the expression levels of SOD1 and SOD2， and SOD activity in PLC/PRF/5 cells were significantly reduced （P＜0.05）. After down-regulating AFP expression in PLC/PRF/ 5 cells， compared with PLC/PRF/5 group， the expression levels of SOD1 and SOD2， as well as SOD activity， were significantly increased in the PLC/PRF/5-shAFP group （low-expression） （P＜0.05）. After 48 hours of SOD treatment， compared with control group， the scratch healing rates of PLC/PRF/5 cells in the 0.375， 0.75， 1.5 and 3 U/mL SOD groups were significantly reduced （P＜0.05）； after 72 hours of SOD treatment， compared with control group， the scratch healing rates of PLC/PRF/5 cells in the 0.375， 0.75， and 1.5 U/mL SOD groups were significantly reduced （P＜0.05 or P＜0.01）. Compared with control group， proliferation rates of PLC/PRF/5 cells were significantly reduced in the 0.375， 0.75， 1.5 and 3 U/mL SOD groups （P＜0.05 or P＜0.01）. Compared with the PLC/PRF/5 group before up-regulating SOD1 and SOD2 expression， the expression levels of AFP and Src in the PLC/PRF/5-oeSOD1 and PLC/PRF/5-oeSOD2 groups （over-expression） after up-regulating SOD1 and SOD2 expression were significantly reduced （P＜0.05）. CONCLUSIONS A certain concentration of SOD can inhibit malignant behavior such as migration and proliferation of PLC/PRF/5 cells， and the expression level and activity of SOD are negatively correlated with AFP.

OBJECTIVE To study the effect and safety evaluation of percutaneous tracheotomy and traditional open tracheotomy in patients with severe pulmonary infection in ICU environment.METHODS A retrospective analysis was conducted on 80 patients with severe pulmonary infections admitted to the ICU of Shangqiu First People's Hospital from July 2019 to June 2022 as the subjects of the study.According to the tracheotomy approach,they were divided into the Percutaneous tracheotomy group(n=40)and the Conventional tracheotomy group(n=40).The Conventional tracheotomy group underwent traditional routine tracheotomy,while the Percutaneous tracheotomy group underwent percutaneous tracheotomy;all tracheotomies were performed by the same physician.The two groups were compared based on different tracheotomy techniques,and the surgical incision time,intraoperative blood loss,complete healing indicators were analyzed to evaluate the surgical outcomes and complication rates in each group.RESULTS Compared with the Conventional tracheotomy group,the Percutaneous tracheotomy group significantly reduced surgical time,intraoperative blood loss,and wound healing time after extubating(P<0.05),and the incidence of complications such as difficult cannulation,pneumothorax and subcutaneous emphysema decreased significantly,and the difference was statistically significant(P<0.05).In the BMI subgroup analysis of complications,it was found that in the BMI≥28.0 kg/m2 subgroup,the incidence of casing difficulty and pneumothorax complications in the Percutaneous tracheotomy group was lower than that in the Conventional tracheotomy group,and the difference was statistically significant(P<0.05).In the 22.0 kg/m2≤BMI<28.0 kg/m2 subgroup and BMI<22.0 kg/m2 subgroup,there was no significant difference in the difficulty of cannulation and pneumothorax complications between the two groups(P>0.05).CONCLUSION In ICU patients with severe pneumonia,early percutaneous tracheotomy can significantly reduce intraoperative bleeding blood volume,shorten the time of tracheotomy,especially in patients with BMI≥28.0 kg/m2,which has a lower incidence of complications.Percutaneous tracheotomy is worth promoting in ICU patients with severe lung infection who need tracheotomy.

Objective To investigate the risk factors of aspiration during early enteral nutrition(EEN)support treatment in patients in intensive care unit(ICU)and establish and validate the corresponding nomogram risk prediction model.Methods A total of 348 ICU patients who received EEN between June 2022 and May 2024 were enrolled and divided into the aspiration group(n=74)and the non-aspiration group(n=274)based on the occurrence of aspiration.Clinical data were collected included age,sex,body mass index(BMI),history of diabetes,endotracheal intubation/mechanical ventilation status,plasma albumin(ALB)levels within 24 h after admission to ICU,disease type(severe pneumonia/stroke/septic shock),consciousness level(Glasgow Coma Scale,GCS),APACHE Ⅱscore,nasogastric tube insertion depth,infusion volume,nutritional risk(NRS2002 score≥3 indicating high risk),and nutrition mode(nasogastric/nasointestinal tube).Logistic regression was used to identify risk factors of aspiration,and a nomogram prediction model was constructed using R software.External validation was performed on 72 EEN-treated ICU patients admitted between June 2024 and January 2025.Results Logistic regression identified age(OR=2.701,95%CI:1.633-4.467),APACHE Ⅱ score(OR=2.125,95%CI:1.133-3.987),consciousness level(OR=2.826,95%CI:1.617-4.940),nasogastric tube insertion depth(OR=1.101,95%CI:1.006-1.136)and nutritional risk(OR=8.996,95%CI:5.017-16.132)were independent risk factors for aspiration(all P＜0.05).A nomogram incorporating these factors was developed,converting cumulative scores into individualized aspiration risk probabilities.The model demonstrated strong predictive performance in internal validation(AUC=0.860,calibration curve slope=0.930)and external validation(AUC=0.831).Decision curve analysis(DCA)confirmed significant clinical net benefits across risk thresholds,supporting its practical utility.Conclusion The nomogram model exhibits good discrimination and accuracy,providing a valuable tool for individualized aspiration risk assessment in ICU patients receiving EEN.
