OBJECTIVE To investigate the actual construction and operation status of established and under-construction centralized （cloud） prescription review centers （shortened for “prescription review center”） of close-knit county-level medical consortium in a certain city， so as to provide reference for improving the construction quality of the prescription review center. METHODS An online questionnaire survey was conducted to collect the data from 51 established and under-construction prescription review center in the city， covering basic information， funding sources， talent management， system construction， review rule maintenance， prescription review practices， prescription evaluation， data utilization， and current challenges. The collected data were summarized and analyzed. RESULTS A total of 51 valid questionnaires were retrieved， covering 32 established and 19 under-construction prescription review center. Among the 32 established prescription review centers， the main funding sources for their construction came from government financial allocations， accounting for 56.25%. Only 25.00% of prescription review center had review pharmacists who fully met national qualification requirements， and just 55.00% updated more than 10 review rule entries per month on average. Outpatient prescription verification realized full coverage， but 37.50% of prescription review centers only supported rationality verification of single prescriptions， and 50.00% could not retrieve laboratory and examination results to assist in prescription review. Additionally， 40.62% of prescription review center had not regularly conducted prescription evaluations for primary care institutions. The data from prescription review center was mainly used to support medication monitoring. Among the 19 prescription review centers currently in the planning stage， 63.16% had no identified funding sources. CONCLUSIONS The operation and construction of prescription review center in the city face challenges， such as funding shortages， absence of collaborative incentive mechanisms， and insufficient manpower.It is suggested that the state should issue a unified standard for the construction of the prescription review center as soon as possible， and local health administrative departments should formulate supporting policies and clarify assessment indicators in combination with the actual situation of the region.

Objective: Randomized controlled trials (RCTs) of Chinese patent medicines and classic traditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023. A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments. This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence. Methods: RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evidence Database for Chinese Patent Medicine (AICED-CPM), with supplementary searches conducted in China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, PubMed, Embase, and Web of Science. The study characteristics and methodological quality of these RCTs were systematically analyzed and evaluated. Results: A total of 1 443 RCTs of Chinese patent medicines were included, comprising 1 399 Chinese articles and 44 English articles. Additionally, 334 RCTs of classic traditional Chinese medicine prescriptions were found, with 331 published in Chinese and 3 in English. 196 567 participants were included, covering 585 types of Chinese patent medicines (487 oral, 61 injectable, and 37 topical) and 179 classic traditional Chinese medicine prescriptions. The involved studies encompassed 22 types of diseases, with research primarily focusing on diseases of the circulatory system, the respiratory system, and the genitourinary system. The sample sizes ranged from 18 to 3 777 participants, and most studies were conducted at a single center. Methodologically, the implementation of allocation concealment and blinding remained insufficiently emphasized. Conclusion Overall, compared with 2022, both the number of RCT publications and their methodological quality have improved in 2023, with heightened attention to research on diseases of the genitourinary system. However, quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence.

Objective:To analyze the drug-resistance pattern and molecular epidemiological characteristics of Enterobacteriales carrying the blaNDM gene in Lishui, aiming to guide clinical anti-infection treatment. Methods:Non-duplicate blaNDM-carrying Enterobacteriales, isolated from Lishui Central Hospital, were collected and identified by VITEK MS. The minimal inhibitory concentrations (MICs) were detected by the broth microdilution method. The ST types of the strains were determined by multilocus sequence typing (MLST). Plasmid types were identified by transformation or conjugation experiments and replication initiator amplification experiments. The transposon structures were detected by PCR amplification. Finally, the epidemic regularity of blaNDM gene in Lishui was analyzed from three levels: clonal group, plasmid, and mobile genetic elements. Results:A total of 109 blaNDM-positive strains were collected. Among them, 60 strains carried the blaNDM-1 gene and 49 strains carried the blaNDM-5 gene. The 109 strains showed 100% resistance to ceftazidime and cefotaxime. The resistance rates to peracillin-tazobactam and imipenem were higher than 80%. Strains carrying the blaNDM-5 gene were more resistant to meropenem than those carrying blaNDM-1 gene( P<0.05). A total of 68 STs were detected from 109 strains, and IncX3, IncFⅡγ, IncA/C and IncT/R plasmids were detected, and 90.83% of the blaNDM genes were located in the IncX3 plasmid. Twelve types of blaNDM gene surrounding structures existed, and they all carried the highly conserved blaNDM- bleMBL- trpF gene sequence. Conclusions:The blaNDM gene has diverse transmission modes in Lishui. The IncX3 plasmid is the main factor mediating its transfer, and all strains carry highly conserved blaNDM- bleMBL- trpF gene sequence.

Objective To investigate the value of olfactomedin domain family 4(OLFM4),cathepsin C(CTSC),LL-37 and procalcitonin(PCT)combined detection in the early diagnosis of bacterial infection in pa-tients with trauma or surgery.Methods A total of 160 patients with trauma or surgery admitted to a hospital from January to July 2023 were selected for blood culture or secretion culture.According to the results of bac-terial culture,120 patients with positive bacterial culture were selected as positive group and 40 patients with negative bacterial culture were selected as negative group.The positive group was divided into 53 Gram-nega-tive bacteria infection group(G-bacteria group)and 67 Gram-positive bacteria infection group(G+bacteria group)according to the types of pathogens.Another 30 healthy subjects in a hospital during the same period were selected as the control group.The serum levels of OLFM4,CTSC,LL-37 and PCT,and the relative mR-NA expression levels of OLFM4,CTSC and LL-37 in neutrophils were compared among all groups and posi-tive groups.Results Serum levels of OLFM4,CTSC,LL-37 and PCT in negative and positive groups were significantly higher than those in control group,with statistical significance(P＜0.05).The relative expres-sion levels of OLFM4,CTSC and LL-37 mRNA in negative and positive groups were significantly higher than those in control group,with statistical significance(P＜0.05).The serum PCT level of G-bacteria group was significantly higher than that of G+bacteria group,and the differences was statistically significant(P＜0.05).The serum levels of CTSC and LL-37 in patients with sensitive bacteria were significantly higher than those in patients with drug-resistant bacteria,and the serum levels of OLFM4 in patients with drug-resistant bacteria were significantly higher than those in patients with sensitive bacteria,with statistical significance(P＜0.05).The relative expression levels of CTSC mRNA and LL-37 mRNA in neutrophils in patients with sensitive bacteria were significantly higher than those in patients with drug-resistant bacteria,and the differ-ences were statistically significant(P＜0.05).Conclusion PCT can be used as an early diagnosis and evalua-tion index of bacterial infection in patients with trauma or surgery.OLFM4 and LL-37 can better distinguish the infection of sensitive bacteria from drug-resistant bacteria and judge the curative effect and prognosis.

Objective To develop a novel drainage catheter based on the anatomical structure of the mammary duct and establish a non-invasive treatment protocol for patients with acute high-tension breast milk cyst during lactation.Methods Ten primiparous patients with acute high-tension breast milk cyst during lactation,admitted to the postpartum clinics of three hospitals,were enrolled as study subjects.A novel drainage catheter was prepared using an epidural anesthesia catheter,and intubation was performed to unblock the obstructed mammary ducts.For cases with intubation failure,puncture as-piration was employed.Local cold compresses were applied to the breasts after treatment.Results Out of 10 patients,6 were successfully unblocked(successful group),and 4 failed(failure group).The duration of illness in the successful group was(6.00±0.82)days,which was shorter than that in the failure group[(9.50±1.80)days](P＜0.05).The insertion depth of the catheter in the successful group was(6.42±0.67)cm,which was greater than that in the failure group[(4.00±0.71)cm](P＜0.05).There was no statistically significant difference in cyst diameter between the two groups(P＞0.05).For patients in whom unblocking failed,puncture aspiration was performed,and 3 of them experienced recurrence after the initial puncture.Ultrasound-guided re-puncture aspiration and weaning were performed.One patient with evident inflammatory symptoms was administered systemic antibiotic therapy.After treatment,7 patients resumed lactation,and follow-up results indicated that all 10 patients were cured.Conclusion Acute high-tension breast milk cyst during lactation is rela-tively rare in clinical practice.The novel drainage catheter can achieve non-invasive unblocking of distally obstructed mammary ducts in the lactiferous sinus.The comprehensive treatment protocol can improve the overall cure rate and result in a high rate of resumed lactation post-treatment.

Objective: To analyze the temporal changes in lipid levels in patients following acute pancreatitis(AP) and explore the factors associated with post-AP serum triglyceride( TG) level changes. Methods: Patients diag- nosed with AP were included in this study. Clinical data were collected retrospectively , and lipid profile data from follow-up visits after discharge were tracked. Kaplan-Meier(K-M) curves were used to stratify follow-up duration ,iodine content detection. Thyroid volume was measured using a fully digital ultrasound imaging system , and goiter prevalence was calculated. Results: A total of 141 patients with 306 follow⁃up visits were included. Spearman correlation analysis showed a mild increase in lipid levels over time post⁃discharge : TG( r = 0. 159 , P = 0. 005) , total cholesterol(TC)( r = 0. 231 , P < 0. 000 1) , high⁃density lipoprotein cholesterol( HDL⁃C) ( r = 0. 181 , P = 0. 002) , and apolipoproteinA1 ( ApoA1) ( r = 0. 371 , P <0. 000 1) . In the univariate linear mixed model , male gender(β = 0. 160 ,P = 0. 007) , body mass index(BMI) (β= 0. 017 , P = 0. 007) , diabetes history(β = 0. 138 , P = 0. 030) , smoking history(β = 0. 166 ,P = 0. 004) , and recurrent AP(β = 0. 119 , P = 0. 029) were significantly associated with Lg(TG) levels (P < 0. 05) . In the multivariate model , BMI( β = 0. 019 , P = 0. 042) , smoking history ( β = 0. 155 , P = 0. 049 ) , and recurrent AP( β =0. 148 , P = 0. 032) remained significantly positively correlated with changes in Lg(TG) levels after AP , albeit with a low correlation strength (r < 0. 200) . Conclusion Lipid levels , including TG , TC , HDL⁃C and ApoA1 , tend to increase over time in AP patients after discharge , with this trend being more pronounced in those with hypertriglyceridemic acute pancreatitis. Post⁃AP TG levels are significantly influenced by BMI at the time of onset , smoking history and recurrent AP.

AIM:To investigate the effect of intrinsic specific transforming growth factor-β(TGF-β)signaling on regeneration and repair of myofibers in acute skeletal myositismice model induced by cardiotoxin(CTX).METHODS:One hundred and eighty-six wild C57BL/6 mice and one hundred and thirty-eight mice with conditional knockout of TGF-β receptor 2(TGF-βr2)in myofibers(SM TGF-βr2-/-mice)were selected.CTX injection to anterior tibial muscle(TA)in-duced acute myoinjury in mice.Some SM TGF-βr2-/-mice were given Smad signaling agonist SRI-011381(SRI)intramus-cular injection.All mice were mainly divided into the following groups:control group,SM TGF-βr2-/-group and SM TGF-βr2-/-+SRI group.Twenty-four mice were selected in each group.RT-qPCR and immunofluorescence staining were used to detect the relative mRNA level,protein expression of inflammatory cytokines and low-density lipoprotein receptor-related protein 1(LRP1),respectively,while the relative protein expression of myosin heavy chain 3(MHY3)and embryonic myosine heavy chain(eMHC)in damaged muscle was detected by Western blot and immunofluorescence staining.In vi-tro,after being extracted from neonatal mice,myogenic precursor cells(MPCs)were cultured in an pro-inflammatory mi-lieu and treated with SRI,recombinant mouse extracellular matrix protein 1(rmECM1)alone or in combination.Hereby,they were divided into the following seven groups:control-MPCs group,control-MPCs+LPS group,TGF-βr2-/--MPCs group,TGF-βr2-/--MPCs+LPS group,TGF-βr2-/--MPCs+LPS+SRI group,TGF-βr2-/--MPCs+LPS+rmECM1 group,and TGF-βr2-/--MPCs+LPS+SRI+rmECM1 group.Six mice were selected in each group.RT-qPCR and Western blot were used to detect the relative mRNA level,protein expression of major histocompatibility complex class I molecules(MHC-I/H-2Kb),major histocompatibility complex class II molecules(MHC-II/H2-Eα),Toll-like receptor 3(TLR3),and LRP1.And the relative protein expression of MoyD and myogenin in myotubes was detected by immunofluorescence staining.RE-SULTS:In vivo,compared with control group,SM TGF-βr2-/-group showed the significant upregulation of pro-inflamma-tory cytokines(P<0.05),and the opposite trend of anti-inflammatory cytokines,LRP1,MHY3,eMHC in the injured muscle(P<0.05),with delayed regeneration and repair of myofibers.In vitro,compared with control-MPCs+LPS group,LRP1,MoyD and myogenin significantly downregulated in TGF-βr2-/--MPCs+LPS group,but the downregulation trend was corrected after giving SRI treatment(P<0.05).In addition,compared with the TGF-βr2-/--MPCs+LPS group,the combi-nation of rmECM1 and SRI significantly upregulated the protein expression of MyoD and myogenin(P<0.05).CONCLU-SION:In a mouse model of acute skeletal myositis,intrinsic TGF-β signaling specifically in myofibers regulates local im-mune behavior.It promotes the expression of LRP1 in damaged muscle via Smad2/3 signaling,and LRP1 can then fully bind to ECM1,thereby facilitating muscle regeneration and repair,and improving the prognosis of acute skeletal myositis.

Objectives:To investigate the prognostic difference of different revascularization strategies in AMI patients with multi-vessel disease and diabetes.Methods:AMI patients with multi-vessel disease and diabetes admitted to the Department of Cardiology of the First Hospital of Lanzhou University from January 2022 to June 2024 were retrospectively included.Patients were divided into non complete revascularization(NCR)group(n=166),staged complete revascularization(SCR)group(n=152)and immediate complete revascularization(ICR)group(n=120).Baseline clinical characteristics,coronary angiography data and postoperative medication were compared among the groups.Primary endpoint was the major adverse cardiovascular and cerebrovascular events(MACCE)during follow-up.MACCE includes all-cause mortality,cardiogenic mortality,non-fatal myocardial infarction,unplanned revascularization and stroke.The log-rank test was used to analyze the significance of the differences in the cumulative incidence of MACCE among the three groups.Cox regression was used to explore the influencing factors of poor prognosis in patients.Results:There were statistically significant differences among NCR group,SCR group and ICR group in terms of the history of previous percutaneous coronary intervention,the use of intraoperative coronary intravascular ultrasound(IVUS)and the dosage of contrast agent(all P<0.05).During a median follow-up of 21(11,25)months,MACCE events occurred in 59 cases(35.5%)in the NCR group,26 cases(17.1%)in the SCR group,and 30 cases(25.0%)in the ICR group.The Kaplan-Meier curve showed that the differences in the cumulative incidence of MACCE among the three groups were statistically significant(log-rank P<0.001).Using the Bonferroni correction(adjusted α′=0.05/3≈0.0167),pairwise comparisons revealed statistically significant differences between the NCR and SCR groups(log-rank P<0.001)and between the NCR and ICR groups(log-rank P=0.011).However,no statistically significant difference was observed between the SCR and ICR groups(log-rank P=0.228).Cox multivariate regression analysis demonstrated that history of hypertension was an independent risk factor for MACCE in AMI patients with multivessel coronary artery disease and diabetes(HR=1.71,95%CI:1.10-2.64,P<0.05).The difference in the incidence of MACCE between the SCR group and the NCR group was statistically significant(HR=0.45,95%CI:0.28-0.73,P=0.001).Conclusions:Staged complete revascularization serves as the preferred revascularization strategy for AMI patients with multivessel coronary disease and diabetes mellitus.Additionally,for patients with concomitant hypertension,blood pressure management should be intensified to reduce the risk of MACCE.

Objective:To identify risk factors for developing infected pancreatic necrosis (IPN) in female hypertriglyceridemia-induced acute pancreatitis (HTG-AP) patients with childbearing age.Methods:A retrospective analysis was conducted on clinical data from 460 female HTG-AP patients with childbearing age admitted to Eastern Theater General Hospital of the Chinese People's Liberation Army between December 2013 and December 2022. Patients were divided into the IPN group ( n=140) and non-IPN group ( n=320) based on the occurrence of IPN. General clinical data, laboratory test results and clinical outcomes were compared between the two groups. Univariate and multivariate logistic regression models were used to analyze the risk factors for IPN in reproductive-age HTG-AP patients. Results:Among the 460 patients, 140 (30.4%) developed IPN. Compared with the non-IPN group, the IPN group had a significantly higher proportion of pregnant patients (30.0% vs 10.9%, P<0.001) and a lower proportion with a history of acute pancreatitis (12.9% vs 31.3%, P<0.001). Laboratory findings showed that patients in the IPN group had lower levels of hemoglobin and albumin, but higher levels of blood urea nitrogen and serum creatinine. Clinical outcomes showed that the IPN group had significantly higher rates of severe acute pancreatitis and mortality compared to the non-IPN group. Additionally, the median length of ICU stay and total hospital stay in the IPN group were significantly longer, at 16.5 days and 32.0 days, respectively. Univariate logistic regression analyses showed that pregnancy, previous history of acute pancreatitis, and levels of hemoglobin, total bilirubin, albumin, blood urea nitrogen and creatinine were significantly associated with IPN. Multivariate logistic regression analysis revealed that pregnancy ( OR=2.617, 95% CI 1.494-4.210, P=0.001), a history of acute pancreatitis ( OR=0.339, 95% CI 0.189-0.711, P=0.002), hemoglobin level ( OR=0.945, 95% CI 0.939-0.987, P<0.001), and blood urea nitrogen level ( OR=1.173, 95% CI 1.056-1.198, P=0.004) were independently associated with the occurrence of IPN. Conclusions:Pregnancy, a first episode of acute pancreatitis, lower hemoglobin levels and higher blood urea nitrogen levels are independent risk factors for IPN in female HTG-AP patients with childbearing age.
