Objective:To overview the systematic reviews of prevention and management measures of medication errors, so as to provide evidence support for clinical decision-making for medical staff.Methods:Cochrane Library, Australia Joanna Briggs Institute Evidence-based Healthcare Center database, CINAHL, PubMed, Embase, CNKI, SinoMed, Wanfang database and VIP database were searched by computer to search for systematic reviews of prevention and management measures of medication errors, and the search period was from establishment of the databases to June 30, 2023. Two researchers with systematic evidence-based training applied A Measure Tool to Assess Systematic Reviews 2 (AMSTAR 2) to evaluate the literature quality, and Grades of Recommendations Assessment, Development and Evaluation (GRADE) was used to evaluate the quality of outcome indicators.Results:Finally, a total of 19 systematic reviews were included. The overall quality evaluation using AMSTAR 2 was relatively low, with one article rated as high-quality, one article rated as low-quality and 17 articles rated as extremely low-quality. According to the evidence quality evaluation results of GRADE system for 55 outcome indicators of 19 systematic reviews, 3 pieces of evidence were medium, 27 pieces of evidence were low and 25 pieces of evidence were extremely low, indicating an overall low quality of evidence.Conclusions:The related researches on prevention and management of medication errors have been carried out extensively, and the computer system is one of the effective measures to reduce medication errors. The effectiveness of measures such as administration process modification, doctor/nurse education and training, double check, pharmacist intervention, automated dispensing cabinet/ automated pump and drug display is still unclear and needs to be further confirmed by large sample size and high-quality studies.

Objective To investigate the effects of lncRNA SBF2-AS1 on the proliferation and invasion of hepatoma cells by regulating the miR-372-3p/CDK6 pathway. Methods Bel7402 and SK-hep1 cells were selected as research objects. The expression levels of SBF2-AS1, miR-372-3p, and CDK6 were up- or down-regulated according to different experimental stages, while the expression levels of miR-372-3p and CDK6 in cells were detected by real-time fluorescence quantitative PCR and Western blot. Dual luciferase reporter assay verified the targeting relationships between SBF2-AS1 and miR-372-3p as well as miR-372-3p and CDK6, respectively. CCK-8, colony formation assay, Transwell, cell cycle assay, and flow cytometry were used to analyze cell proliferation, colony formation, migration/invasion ability, cell cycle activity, and apoptosis. Results SBF2-AS1 was highly expressed in hepatocellular carcinoma cells (P<0.05). SBF2-AS1 knockdown resulted in decreased proliferation and invasion of Bel7402 and SK-hep1 cells (P<0.05). After miR-372-3p knockdown, the proliferation capacity and invasion number of Bel7402 cells were significantly increased. However, the above results were reversed after SBF2-AS1 knockdown (P<0.05). In addition, miR-372-3p targeted CDK6 and inhibited its expression, although over-expressing SFB2-AS1 could reverse the above results (P<0.05). Over-expressing CDK6 could reverse the inhibition of over-expressing miR-372-3p on the proliferation and invasion of Bel7402 cells. Conclusion LncRNA SBF2-AS1 can positively regulate the expression of CDK6 through miR-372-3p. It can also influence the distribution of cell cycle and affect the proliferation and invasion abilities of hepatocellular carcinoma cells.

Objective:To synthesize Gd labeled probe targeting transporter protein(TSPO) 2-(8-amino-2-(4-chlorophenyl)imidazo[1, 2-a]pyridine-3-yl)- N, N-dipropylacetamide (CB86)-diethylene triamine pentaacetic acid (DTPA), and investigate its MRI effect in rheumatoid arthritis (RA) model. Methods:CB86-DTPA was prepared by coupling a bifunctional chelating agent, and then chelated with Gd to obtain MRI targeted contrast agent CB86-DTPA-Gd. The cytotoxicity, MR relaxation rate and in vitro stability of CB86-DTPA-Gd were determined. RA model was established with Freund′s adjuvant and the biodistribution study and MRI was performed. The RA lesion and its surrounding normal tissue were used as regions of interest (ROI) to calculate the signal to noise ratio (SNR). Independent-sample t test was used to analyze the data. Results:CB86-DTPA-Gd had excellent biosafety and a good MR relaxation rate ( r1=11.05 mmol·L -1·s -1). The survival rate of RAW264.7 cells and 4T1 cells was still more than 90% at the maximum concentration (20 μmol/L) of Gd 3+. CB86-DTPA-Gd also exhibited good stability in human serum and phosphate buffer saline solution (PBS; pH=7.4). The in vivo biodistribution showed that CB86-DTPA-Gd had better inflammatory targeting efficiency, and the uptake of Gd in the inflamed site of the ankle joint was still (2.33±0.29) percent dose rate per gram of tissue (%ID/g) at 120 min after injection. MicroMRI showed that the inflammation of the right ankle joint displayed significant enhancement after the injection of CB86-DTPA-Gd and Gd-DTPA. The SNR of CB86-DTPA-Gd group was up to 23.21±1.44, and the maximum intensification time was 90 min after injection, and can be significantly inhibited by CB86-DTPA at all time points ( t values: 6.083-12.451, all P<0.05), while the Gd-DTPA group had a strengthening time of 30 min after injection with the SNR of 16.12±1.24. Conclusion:CB86-DTPA-Gd shows good macrophage targeting and good uptake in arthritic reaction sites, and is expected to be a novel MRI molecular probe for peripheral inflammation imaging.

ObjectiveTo investigate the expression and clinical significance of serum exosomal microRNA(miRNA)-221-3p in hepatocellular carcinoma (HCC). MethodsA total of 66 patients who underwent surgery in Nanjing Drum Tower Hospital, Nanjing University Medical School, from February 2010 to December 2014 and were diagnosed with HCC were enrolled as HCC group, and 25 individuals who underwent physical examination in our hospital during the same period of time were enrolled as control group. The exosome extraction kit was used to isolate the exosomes in serum; Western blotting was used to measure the expression of exosome markers; a transmission electron microscope was used to observe the morphology of serum exosomes; quantitative real-time PCR was used to measure the expression of serum exosomal miRNA-221-3p. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method and the log-rank test were used to analyze the association of the expression of serum exosomal miRNA-221-3p with prognosis, and the Cox proportional hazards regression model was used to analyze the influencing factors for prognosis. ResultsSerum exosomes were small membranous vesicles with a diameter of about 40-100 nm, and HSP70, Alix, and CD63 were expressed in the exosomes. The HCC group had significantly higher expression of serum exosomal miRNA-221-3p than the control group (U=354.00, P＜0.001). In the patients with HCC, the high expression of serum exosomal miRNA-221-3p was associated with tumor size (χ2=6.016, P=0.014), capsular invasion (χ2=7.580, P=0.006), and TNM stage (χ2=6.340, P=0012). In addition, the HCC patients with high expression of serum exosomal miRNA-221-3p had a significantly lower overall survival rate than those with low expression (χ2=17.105, P＜0.001). The multivariate analysis showed that the expression of serum exosomal miRNA-221-3p (hazard ratio ［HR］=2.434, 95% confidence interval ［CI］: 1.178-5.027, P=0.016) and tumor stage (HR=2.653, 95% CI: 1.222-5.760, P=0.014) were independent risk factors for the prognosis of patients with HCC. ConclusionThere is a significant increase in the expression of serum exosomal miRNA-221-3p in HCC patients, which provides a reference for the diagnosis and prognostic evaluation of HCC.

Objective To investigate the technical and therapeutic effects of laparoscopic surgery for adult patients with Dong Type C bile duct dilatation.Methods A retrospective cohort study approach was used.The clinical data of 47 patients with Dong Type C adult biliary dilatation who underwent surgery in Fujian Provincial Hospital from January 2014 to December 2017 were collected.There were 12 males and 35 females.The age ranged from 16 to 68 years,with a median age of 30 years.According to different surgical methods,the patients were divided into the laparoscopic group (treated with laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy,n =21) and the open group (treated with traditional open operation,n =26).The intraoperative blood loss,complication rate,operation time,postoperative intestinal function recovery time and postoperative hospital stay were observed.Measurement data with normal distribution were expressed as mean ± standard deviation (Mean ±SD) and analyzed by t test.Comparison of count data was done by the chi-square test.Results There was no perioperative deaths in either group.There was no significant difference in intraoperative blood loss and complication rate between the two groups (P ＞ 0.05).The operation time of the laparoscopic group was significantly longer than that of the open group[(333.7 ±61.1) min vs (235.9 ±64.3) min],with statistically significant difference between graps (P =0.000).The recovery time for the intestinal function of the laparoscopic group was significantly shorter than that of the open group [(2.2 ± 0.5) d vs (2.9 ± 0.6) d],with statistically significant difference between groups (P =0.000).The postoperative hospital stay in the laparoscopic group was significantly shorter than the open group [(7.1 ± 1.8) d vs (12.0 ± 5.9) d],with statistically significant difference between groups (P =0.001).Conclusion For adult biliary dilatation patiens with Dong Type C,laparoscopic surgery is safe and feasible with the advantages of mini-invasive and quick recovery.

Objective To synthesize a novel 18 F labeled probe targeting translocator protein ( TSPO) ligand 2-( 5, 7-diethyl-2-( 4-( 2-fluoroethoxy ) phenyl ) pyrazolo [ 1, 5-a ] pyrimidin-3-yl )-N, N-diethylacet-amide (VUIIS1008), and evaluate its biodistribution and imaging in rheumatoid arthritis (RA) model. Methods The tosylate substrate was labeled with 18 F using a tosyloxy for fluorine nucleophilic aliphatic substitution to obtain 18 F-VUIIS1008. The labeling efficiency, radiochemical purity, and stability in vitro were determined. In vitro cellular uptake and competitive binding assay were performed on RAW264.7 mac-rophage cells. Biodistribution and microPET/CT imaging were investigated on RA mice established by Com-plete Freund's Adjuvant. Two-sample t test was used to analyze the data. Results 18 F-VUIIS1008 was syn-thesized with the labeling yield up to (41.00±5.00)％, the radiochemical purity>98.00％, and the specific radioactivity >1. 52 × 108 MBq/mmol. 18 F-VUIIS1008 was highly stable with the radiochemical purity >98. 00％ at 4 h after incubation in mouse serum. In vitro, it also exhibited high specific TSPO binding in RAW264.7 macrophage cells. The uptake ratio was (14.00±0.30)％ at 1 h after incubation, and decreased significantly ((4.00±0.70)％;t=12.894, P<0.05) after adding excessive unlabeled VUIIS1008. The half maximal inhibitory concentration (IC50) of 18F-VUIIS1008 binding to TSPO was 0.05 nmol/L in RAW264.7 macrophage cells. In vivo distribution results showed that the uptake of 18 F-VUIIS1008 in the left arthritic ankles reached the peak value of (1.33±0.02) percentage activity of injection dose per gram of tissue (％ID/g) at 1 h after injection. The radioactivity ratio of left ankle arthritic tissue to blood ( A/B) and to normal muscle ( A/M) was 4.40±0.22 and 1.65±0.07 respectively. MicroPET/CT imaging demonstrated that 18F-VUIIS1008 could specifically target and retained in the inflammation site. Conclusion 18 F-VUIIS1008 can be easily synthe-sized with high radiochemical purity and can clearly visualized in RA imaging with low background, suggesting its potential as a novel promising molecular probe targeting TSPO for RA PET imaging.
