Traditional treatment for type 1 diabetes mellitus （T1DM） primarily involves insulin replacement， yet some patients encounter issues such as significant blood glucose fluctuations， high risk of hypoglycemia， and weight gain. In recent years， the adjuvant therapeutic role of non-insulin hypoglycemic drugs in T1DM has gradually gained attention. This article reviews the mechanisms of action and clinical research progress of five types of non-insulin hypoglycemic drugs in the treatment of T1DM： amylin analogues （pramlintide）， biguanides （metformin）， sodium-glucose co-transporter 2 inhibitor， dipeptidyl peptidase-4 inhibitor， and glucagon-like peptide-1 receptor agonist. It is found that these drugs can enhance clinical benefits for T1DM patients by improving insulin sensitivity， delaying gastric emptying， promoting urinary glucose excretion， and regulating incretin levels， thereby reducing glycated hemoglobin levels， decreasing insulin dosage， and managing body weight. Simultaneously， these drugs also present limitations such as low patient compliance due to complex dosing regimens， increased risk of diabetic ketoacidosis， and heterogeneity in glycemic control. Future research could focus on developing individualized treatment strategies， combining pharmacogenomics with novel biomarkers to precisely identify subpopulations of patients who may benefit， and delving into the potential value of these drugs in delaying diabetic vascular complications and improving patients’ quality of life.

OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

[Objective] To investigate the pathological characteristics of false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT based on the pathology of whole mount specimens, in order to more accurately assess the degree of malignancy within the prostate tissue and avoid overdiagnosis and unnecessary treatment. [Methods] A total of 77 patients who underwent ⁶⁸Ga-PSMA-11 PET/CT before radical prostatectomy in Nanjing Drum Tower Hospital during Jan.2018 and Dec.2022 were retrospectively analyzed.The pathology of whole mount specimens was detected.Two nuclear physicians examined all imaging plates without knowing the pathological results.Two pathological physicians completed all pathological diagnosis without knowing the imaging results.The pathological characteristics of false-positive lesions were determined by matching ⁶⁸Ga-PSMA-11 PET/CT and pathological specimens.To analyze the pathological features of false-positive lesions, true-negative lesions were randomly delineated and defined.The pathological features of false-positive and true-negative lesions were analyzed and compared using Fisher exact test. [Results] After the imaging and pathological sections were matched, 21(16.3%) false-positive lesions were identified.The pathological characteristics of the 21 false-positive lesions were as follows: 16 (76.2%) simple atrophy with cyst formation, 3(14.3%) prostatic nodular hyperplasia, and 2(9.5%) inflammation.The pathological characteristics of 21 true-negative lesions were: 13(61.9%) normal glands, 5(23.8%) prostatic nodular hyperplasia and 3(14.3%) simple atrophy with cyst formation.Fisher exact test showed that the proportion of simple atrophy with cyst formation in the pathological features of false-positive lesions and true-negative lesions was statistically significant (76.2% vs.14.3%, P<0.001). [Conclusion] Simple atrophy with cyst formation may be a characteristic pathological type of the false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT.

Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Ceftazidime-avibactam （CAZ/AVI）is a novel β-lactam antibiotic with broad-spectrum antibacterial activity and good tolerability. However， the physiological and pathological differences in special populations [e.g. augmented renal clearance （ARC） patients， undergoing continuous renal replacement therapy （CRRT） patients， neonates and children， obese patients， undergoing extracorporeal membrane oxygenation （ECMO） patients， elderly patients and liver dysfunction patients] may affect the pharmacokinetic （PK） properties of CAZ/AVI， leading to treatment failure. At present， there is currently a lack of corresponding guidelines or consensus on dose adjustment of CAZ/AVI in special populations. This article summarizes the research on PK/ pharmacodynamic （PD） characteristics and dose adjustment of CAZ/AVI in special populations and recommends the following dosing regimens： for ARC patients， the recommended dose is 2.5 g， q8 h； for undergoing CRRT patients with infections caused by sensitive strains （i.e. MIC＜4 mg/L） and infections at sites where hydrophilic antibiotics distribute well， a dose of 1.25 g， q8 h may be used； for undergoing CRRT patients with less sensitive strains or sites with poorer drug distribution， a dose of 2.5 g， q8 h or continuous infusion may be considered； for children aged 6 months to ＜18 years with normal or mildly impaired renal function， a dose of 62.5 mg/kg， q8 h is infused for 2 h （maximum dose not exceeding 2.5 g per dose）； for infants aged 3～6 months with normal or mildly impaired renal function， a dose of 50 mg/kg， q8 h is infused for 2 h； for obese patients， the recommended dose is 2.5 g， q8 h， with therapeutic drug monitoring recommended；undergoing ECMO patients， elderly patients， and those with impaired liver function may also use the recommended dose of 179368757@qq.com 2.5 g， q8 h.

Objective:To evaluate the diagnostic value of targeted biopsy of secondary lesion (SL) in systematic biopsy (SB) combined targeted biopsy for clinically significant prostate cancer (CsPCa).Methods:A retrospective analysis was conducted on the data of patients who underwent systematic biopsy combined target biopsy at Nanjing Drum Tower Hospital from January 2021 to February 2023, and they had at least two Prostate Imaging-Reporting and Data System (PI-RADS) score ≥3 lesions on prostate magnetic resonance imaging. The study included patients with a median age of 70 (65, 76) years old, median prostate specific antigen (PSA) was 9.1 (5.96, 13.62) ng/ml, median prostate volume was 39.1 (29.27, 53.25) ml, and median PSAD was 0.2 (0.15, 0.38) ng/ml 2.The index lesion (IL) was defined as the one with the highest PI-RADS score and SL was defined as the one with the second-highest PI-RADS score. If the two lesions had the same PI-RADS score, the one with larger maximum diameter was IL and the other one was SL. The median maximum diameter of IL and SL were 1.3 (1.06, 1.66) cm and 0.9 (0.69, 1.20) cm, respectively. The median maximum diameter ratio of IL and SL was 1.48 (1.10, 1.91), and the median maximum diameter difference of IL and SL was 0.9 (0.20, 1.89) cm. The IL in peripheral zone was found in 238 patients (62.63%) and SL in peripheral zone was found in 255 patients (67.10%). There were 204 patients (53.68%) having both IL and SL on the same side of prostate. According to the combination of PI-RADS scores of IL and SL, patients were categorized into various groups: 96 patients (25.26%) with IL3 and SL3, 79 (20.78%) with IL4 and SL3, 98 (25.78%) with IL4 and SL4, 21 (5.52%) with IL5 and SL3, 76 (20.0%) with IL5 and SL4, and 10 (2.63%) with IL5 and SL5. Targeted biopsy was performed on at least two of the most significant lesions. Comparison was performed in the detection rate of CsPCa between SB+ IL+ SL and SB+ IL (SL was omitted). To explore the factors influencing the detection rate of CsPCa, a multivariate logistic regression analysis was used. Results:The detection rate of CsPCa in this study was 78.95% (300/380) based on SB+ IL+ SL. After omitting SL target biopsy, the detection rate of CsPCa was 78.16% (297/380, P>0.05) under the condition of SB+ IL. No significant differences were noted between the two groups. The multivariate logistic regression analysis showed that PSA ( OR=1.11, 95% CI 1.05-1.20, P<0.01), prostate volume ( OR=0.98, 95% CI 0.96-0.99, P<0.01), SL maximum diameter ( OR=0.19, 95% CI 0.08-0.50, P<0.01), ratio of IL and SL maximum diameter ( OR=0.34, 95% CI 0.16-0.68, P<0.01), difference of IL and SL maximum diameter ( OR=1.50, 95% CI 1.10-2.29, P<0.05), and PI-RADS score group of IL and SL (IL3 vs. SL3 as the reference, IL4 vs. SL3 OR=4.79, 95% CI 2.21-10.91, P<0.01, IL4 vs. SL4 OR=23.11 95% CI 8.09-85.28, P<0.01, IL5 vs. SL3/4/5 OR=15.28 95% CI 5.21-48.55, P<0.01) were the influencing factors for detection rate of CsPCa. Conclusions:For patients with at least two PI-RADS score≥3 lesions on prostate magnetic resonance imaging, omitting SL can almost maintain the same detection efficacy.

Objective Gallstone disease(GSD)is one of the common digestive tract diseases with a high worldwide prevalence.The effects of GSD on patients include but are not limited to the symptoms of nausea,vomiting,and biliary colic directly caused by GSD.In addition,there is mounting evidence from cohort studies connecting GSD to other conditions,such as cardiovascular diseases,biliary tract cancer,and colorectal cancer.Early identification of patients at a high risk of GSD may help improve the prevention and control of the disease.A series of studies have attempted to establish prediction models for GSD,but these models could not be fully applied in the general population due to incomplete prediction factors,small sample sizes,and limitations in external validation.It is crucial to design a universally applicable GSD risk prediction model for the general population and to take individualized intervention measures to prevent the occurrence of GSD.This study aims to conduct a multicenter investigation involving more than 90 000 people to construct and validate a complete and simplified GSD risk prediction model.Methods A total of 123 634 participants were included in the study between January 2015 and December 2020,of whom 43 929 were from the First Affiliated Hospital of Chongqing Medical University(Chongqing,China),11 907 were from the First People's Hospital of Jining City(Shandong,China),1 538 were from the Tianjin Medical University Cancer Institute and Hospital(Tianjin,China),and 66 260 were from the People's Hospital of Kaizhou District(Chongqing,China).After excluding patients with incomplete clinical medical data,35 976 patients from the First Affiliated Hospital of Chongqing Medical University were divided into a training data set(n=28 781,80% )and a validation data set(n=7 195,20% ).Logistic regression analyses were performed to investigate the relevant risk factors of GSD,and a complete risk prediction model was constructed.Factors with high scores,mainly according to the nomograms of the complete model,were retained to simplify the model.In the validation data set,the diagnostic accuracy and clinical performance of these models were validated using the calibration curve,area under the curve(AUC)of the receiver operating characteristic curve,and decision curve analysis(DCA).Moreover,the diagnostic accuracy of these two models was validated in three other hospitals.Finally,we established an online website for using the prediction model(The complete model is accessible at https://wenqianyu.shinyapps.io/Completemodel/,while the simplified model is accessible at https://wenqianyu.shinyapps.io/Simplified/).Results After excluding patients with incomplete clinical medical data,a total of 96 426 participants were finally included in this study(35 876 from the First Affiliated Hospital of the Chongqing Medical University,9 289 from the First People's Hospital of Jining City,1 522 from the Tianjin Medical University Cancer Institute,and 49 639 from the People's Hospital of Kaizhou District).Female sex,advanced age,higher body mass index,fasting plasma glucose,uric acid,total bilirubin,gamma-glutamyl transpeptidase,and fatty liver disease were positively associated with risks for GSD.Furthermore,gallbladder polyps,total cholesterol,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,and aspartate aminotransferase were negatively correlated to risks for GSD.According to the nomograms of the complete model,a simplified model including sex,age,body mass index,gallbladder polyps,and fatty liver disease was constructed.All the calibration curves exhibited good consistency between the predicted and observed probabilities.In addition,DCA indicated that both the complete model and the simplified model showed better net benefits than treat-all and treat-none.Based on the calibration plots,DCA,and AUCs of the complete model(AUC in the internal validation data set=74.1%[95% CI:72.9%-75.3%],AUC in Shandong=71.7%[95% CI:70.6%-72.8%],AUC in Tianjin=75.3%[95% CI:72.7%-77.9%],and AUC in Kaizhou=72.9%[95% CI:72.5%-73.3%])and the simplified model(AUC in the internal validation data set=73.7%[95% CI:72.5%-75.0%],AUC in Shandong=71.5%[95% CI:70.4%-72.5%],AUC in Tianjin=75.4%[95% CI:72.9%-78.0%],and AUC in Kaizhou=72.4%[95% CI:72.0%-72.8%]),we concluded that the complete and simplified risk prediction models for GSD exhibited excellent performance.Moreover,we detected no significant differences between the performance of the two models(P>0.05).We also established two online websites based on the results of this study for GSD risk prediction.Conclusions This study innovatively used the data from 96 426 patients from four hospitals to establish a GSD risk prediction model and to perform risk prediction analyses of internal and external validation data sets in four cohorts.A simplified model of GSD risk prediction,which included the variables of sex,age,body mass index,gallbladder polyps,and fatty liver disease,also exhibited good discrimination and clinical performance.Nonetheless,further studies are needed to explore the role of low-density lipoprotein cholesterol and aspartate aminotransferase in gallstone formation.Although the validation results of the complete model were better than those of the simplified model to a certain extent,the difference was not significant even in large samples.Compared with the complete model,the simplified model uses fewer variables and yields similar prediction and clinical impact.Hence,we recommend the application of the simplified model to improve the efficiency of screening high-risk groups in practice.The use of the simplified model is conducive to enhancing the self-awareness of prevention and control in the general population and early intervention for GSD.

Volume loss caused by aging process, diseases, trauma and surgical treatments, could lead to facial depressions, profoundly affecting appearance. Injectable fillers could help to correct this type of disfigurements and are preferred by plastic surgeons and patients due to their quality of minimal invasiveness and better delicateness. Among these fillers, collagen stimulators such as poly-L-lactic acid(PLLA) and polycaprolactone(PCL) are biodegradable synthetic polymers that can stimulate collagen formation and thus gradually restore tissue volume. These polymers have been used worldwide to treat facial aging changes and human immunodeficiency virus-associated facial fat lipoatrophy, demonstrating ideal results in volume enhancement and facial rejuvenation. The progress and clinical applications of compound injectables based on biodegradable collagen stimulators are summarized.

OBJECTIVE To evalu ate relat ed researches about the cost- benefit of pharmaceutical care in medical institutions with cost- benefit analysis，in order to provide evidence-based basis for related policy decisions and provide methodological reference for the cost- benefit evaluation of pharmaceutical care in the future. METHODS Retrieved from PubMed ，Embase，the Cochrane Library ，CBM，Wanfang database ，VIP and CNKI ，cost-benefit analysis was used to evaluate the researches about the cost-benefit of pharmaceutical care in medical institutions. Two researchers independently screened the research and extracted data according to the “Consolidated Health Economic Evaluation Reporting Standards Checklist ”. The quality of included studies was scored and evaluated systematically. RESULTS A total of 46 studies from 17 countries were included. Most of them came from the United States （21.74％），China（19.57％）and France （8.70％）. Average score of 46 literature was 14.30，of which 1 literature was excellent ，5 literature were good ，25 literature were qualified and 14 literature were unqualified. There were 25 research protocols of prospective study type ；the type of pharmaceutical care involved mostly was pharmaceutical monitoring （60.87％）， followed by prescription review （23.91％），medication reconciliation （8.70％）and outpatient pharmacy （6.52％）were less. The median cost-benefit ratio of pharmaceutical care was 5.05 （3.08，11.28）. CONCLUSIONS Pharmaceutical care shows good economic value ，and pharmacists have played an important role in saving medical resources ，but the design level and report quality of the existing studies need to be improved.
