ABSTRACT

OBJECTIVE To explore the mechanism of Taohong siwu decoction (THD) improving peripheral nerve injury induced by paclitaxel (PTX) in rats. METHODS The effects of THD (1 g/mL drug-containing serum) and PTX (0.1 μmol/L) alone or in combination on the proliferation rate of Schwann cells line RSC96 as well as the expressions of lysosomal-associated membrane protein-2 (LAMP2), autophagy marker protein yeast Atg 6 homolog (Beclin1), phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt), and mammalian target of rapamycin (mTOR) were investigated, and then compared with autophagy promoter rapamycin and autophagy inhibitor 3-methyladenine (3-MA). The effects of high-dose and low-dose THD on the expressions of myelin basic protein (MBP) and myelin protein zero (MPZ), S100 calcium-binding protein (S100), LAMP2, Beclin1, PI3K, Akt and mTOR were tested at the end of the experiment. RESULTS After treatment of THD+PTX, the proliferation rate of RSC96 cells was significantly higher than those treated with PTX alone. After treatment of THD+PTX or THD+ 3-MA, the protein expressions of LAMP2 and Beclin1 in RSC96 cells were significantly higher than those treated with PTX or 3- MA alone, while the protein expressions of PI3K, Akt and mTOR were significantly lower than those treated with PTX or 3-MA alone (P<0.05). Compared with model group, the protein expressions of MBP, MPZ, S100, LAMP2 and Beclin1 in sciatic nerve of rats were increased significantly in THD high-dose and low-dose groups, while the protein expressions of PI3K, Akt and mTOR were significantly decreased (P<0.05). CONCLUSIONS THD may activate Schwann cell autophagy by inhibiting the PI3K/Akt/ mTOR signaling pathway, thereby improving peripheral nerve injury caused by PTX.

ABSTRACT

Objective@#Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. @*Methods@#The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. @*Results@#For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. @*Conclusion@#Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.

ABSTRACT

AIM: To investigate the relationship among the fasting plasma glucose coefficient of variation(FPG-CV)and macular morphology and microcirculation in patients with nonproliferative diabetic retinopathy(NPDR).METHODS: A retrospective analysis of 82 cases(82 eyes)with NPDR admitted to our hospital from February 2018 to June 2022 was the research object, and another 82 cases(82 eyes)of non-diabetic retinopathy(NDR)patients during the same period were selected as the control group, and the clinical data of the two groups of patients were analyzed. Multivariate Logistic regression was used to analyze the risk factors affecting the incidence of NPDR, and the back propagation(BP)neural network model was established and evaluated. Pearson correlation was used to analyze the correlation among FPG-CV and macular morphology and microcirculation in patients. RESULTS: The results of multivariate Logistic regression analysis showed that the disease duration ≥7.2a, glycated hemoglobin A1c(HbA1c)≥7.7%, triglyceride(TG)≥1.9 mmol/L, microalbuminuria(MALB)≥24.5 mg/L, FPG-CV ≥9.8%, superficial capillary plexus-vessel density(SCP-VD)<27.6%, deep capillary plexus-vessel density(DCP-VD)<47.7%, foveal avascular zone(FAZ)area ≥0.38 mm2, central retinal thickness(CRT)≥197.7 μm and subfoveal choroidal thickness(SFCT)<227.7 μm were risk factors for NPDR(P<0.05). The number of hidden layer nodes is 5, and the receiver operating characteristic(ROC)curve, calibration curve and clinical decision curve show that the prediction model has good discrimination, accuracy and validity. The results of Pearson correlation analysis showed that FPG-CV was negatively correlated with SCP-VD, DCP-VD and SFCT(P<0.05); FPG-CV was positively correlated with FAZ area and CRT(P<0.05).CONCLUSION: The course of disease, HbA1c, TG, MALB, FPG-CV, SCP-VD, DCP-VD, FAZ area, CRT and SFCT are all related to the pathogenesis of NPDR. With the increase of FPG-CV, the indexes of macular morphology and microcirculation changed. FPG-CV was negatively correlated with SCP-VD, DCP-VD and SFCT and positively correlated with FAZ area and CRT.

ABSTRACT

Methylation plays a vital role in biological systems. SAM (S-adenosyl-L-methionine), an abundant cofactor in life, acts as a methyl donor in most biological methylation reactions. SAM-dependent methyltransferases (MTase) transfer a methyl group from SAM to substrates, thereby altering their physicochemical properties or biological activities. In recent years, many SAM analogues with alternative methyl substituents have been synthesized and applied to methyltransferases that specifically transfer different groups to the substrates. These include functional groups for labeling experiments and novel alkyl modifications. This review summarizes the recent progress in the synthesis and application of SAM methyl analogues and prospects for future research directions in this field.

ABSTRACT

OBJECTIVE@#To investigate the effects of decitabine (DEC) combined with all-trans retinoic acid (ATRA) on the number of immune cells, efficacy and adverse reactions in the treatment of myeloid neoplasms patients.@*METHODS@#Eighty-four patients with myeloid tumors, including AML, MDS-EB-1 or MDS-EB-2 treated by the regimen containing decitabine in our hospital from January 2009 to October 2019 were enrolled and retrospectively analyzed, among the patients, 21 patients treated with DEC alone, 24 patients treated with DEC combined with ATRA (DEC/ATRA) and 39 patients treated with DEC combined with G-CSF priming regimen (DEC/priming). The changes of peripheral blood immune cell levels before and after treatment of the patients between the three groups were compared, and the differences in clinical efficacy and adverse reactions of the patients between the three groups were also compared.@*RESULTS@#There was no statistical differences in the number of immune cells among the patients in the three groups before treatment (P>0.05). NK cell levels decreased significantly in the patients in DEC and DEC/ATRA group after treatment (P<0.05); After treatment, the levels of CD8+ and CD3+T cells in the patients treated by DEC /priming regimen significantly increased (P<0.05), while the levels of CD3-HLA-DR+ B cells significantly decreased (P<0.05). The overall response rate (ORR) of the patients in DEC/ATRA group (75%) and DEC/priming group (74.36%) was significantly higher than 42.86% in DEC monotherapy group, and the differences showed statistically significant (P<0.05), while the ORR between the patients in DEC/ATRA and DEC/priming group showed no statistic differences (P>0.05). There were no statistical differences in overall survival (OS) and incidence of bleeding between the patients in the three groups (P>0.05). The incidences of grade 3 to 4 bone marrow suppression and the infection rate of the patients in DEC monotherapy and DEC/ATRA group were significantly lower than that in DEC/priming regimen group after treatment (all P<0.05), however, there was no statistical difference between DEC monotherapy and the DEC/ATRA group.@*CONCLUSION@#The efficacy of DEC/ATRA on myeloid neoplasms is comparable to that of DEC/priming regimen, and the anti-myeloid tumor effect of DEC/ATRA regimen may be related to the regulation of NK cells and T cells.

ABSTRACT

Objective:To establish a long-term mortality rate prediction model for patients aged 60 years and over with atrial fibrillation and coronary heart disease using the machine learning method, and identify the corresponding risk factors of mortality.Methods:In this retrospective cohort study, a total of 329(11 cases lost of follow-up)patients with 183 males(55.6%)and 146 females(44.4%), aged(77.8±7.3)years, and 142 patients aged 80 years or older(43.2%)were selected in our hospitals from January 2013 to March 2015.And their clinical data on atrial fibrillation and coronary heart disease were analyzed.They were divided into the death group(151 cases)and the survival group(167 cases)according to the survival outcome.In addition, 60 patients aged 60 years and over admitted to our hospitals from April to July 2015 with atrial fibrillation and coronary heart disease were selected as external data validation set.The clinical data included age, gender, body mass index, diagnosis, co-morbidity, laboratory indicators, electrocardiogram, echocardiogram, treatment data.These patients were followed up for at least 6 years, and the main adverse cardiovascular and cerebrovascular events(MACCE), including death, were recorded.Finally, the data of the enrolled patients were randomly divided into the training set and the test set according to the ratio of 9∶1, Different models were established to predict the long-term mortality of patients with atrial fibrillation and coronary heart disease by machine learning algorithm.The optimal model was established by substituting external data(60 cases)into the model for verification and comparison.The top 20 risk factors for mortality were determined by Shapley additive explanation(SHAP)algorithm.Results:A total of 329 hospitalized patients were included in this study, the overall median follow-up time was 77.0 months(95% CI: 54.0~84.0), 11 cases lost during follow-up(3.3%), and 151 cases died(45.9%). The analysis found that the areas under the ROC curve for a support vector machine(SVM)model, k-Nearest Neighbor(KNN)model, decision tree model, random forest model, ADABoost model, XGBoost model and logistic regression model were 0.76, 0.75, 0.75, 0.91, 0.86, 0.85 and 0.81, respectively.The random forest model had the highest prediction efficiency, with the accuracy of 0.789 and F1 value of 0.806, which was better than the logistic regression model[the Area Under Receiver Operating Characteristic Curve(AUC): 0.91 vs.0.81, P<0.05]. D-dimer, age, number of MACCE, left ventricular ejection fraction, serum albumin level, anemia, New York Heart Association(NYHA)grade, history of old myocardial infarction, estimated glomerular filtration rate(eGFR)and resting heart rate were important risk factors for predicting long-term mortality. Conclusions:The random forest model based on machine learning method can predict the long-term mortality of patients with atrial fibrillation and coronary heart disease aged 60 years and over, have a good identification ability.Its accuracy is higher than that of the traditional Logistic regression model.Reducing the long-term mortality and improving the long-term outcomes can be achieved by intervening on D-dimer levels, correcting hypoproteinemia and anemia, improving cardiac function and controlling resting ventricular rates.

ABSTRACT

@#Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

ABSTRACT

【Objective】 To analyze the expression and clinical significance of CD4+ CD69+ T cells in peripheral blood of patients with autoimmune hemolytic anemia. 【Methods】 A total of 206 cases of autoimmune hemolytic anemia admitted to our hospital from March 2018 to March 2021 were selected as the observation group, and 206 cases, who came for healthy physical examination during the same period, were selected as the control group. The levels of CD4+ CD69+ T cells in peripheral blood, CD69 mRNA in CD4+ T cells and CD69 in plasma were detected. The relationship between CD4+ CD69+ T cell level and Hb, reticulocyte ratio (Ret), total bilirubin (TBIL) and indirect bilirubin (IBIL) was analyzed by Pearson correlation analysis to observe the occurrence of venous thromboembolism. The AUC of receiver operating characteristic was used to evaluate the predictive efficacy of CD4+ CD69+ T cell expression in peripheral blood for venous thromboembolism. 【Results】 The levels of CD4+ CD69+ T cells in peripheral blood, CD69 mRNA in CD4+ T cells and CD69 in plasma of observation group were significantly higher than those of control group (P<0.05). Among 206 patients in the observation group, the levels of CD4+ CD69+ T cells in peripheral blood, CD69 mRNA in CD4+ T cells and plasma CD69 in hemolytic attack group were significantly higher than those in remission group, with statistical significance(P<0.05). The Hb in hemolytic attack group was significantly lower while Ret, TBIL and IBIL levels were significantly higher than those in remission group, with statistical significance(P<0.05). Pearson correlation analysis showed that the levels of CD4+ CD69+ T cells in peripheral blood of patients with autoimmune hemolytic anemia were negatively correlated with Hb(P<0.05) while positively correlated with Ret, TBIL and IBIL(P<0.05). According to ROC curve analysis, the expression level of CD4+ CD69+ T cells in peripheral blood predicted that the AUC of patients with autoimmune hemolytic anemia complicated with venous thromboembolism was 0.915(SE: 0.068, OR: 0.002, 95%CI: 0.000~1.000). 【Conclusion】 The up-regulated expression level of CD4+ CD69+ T cells in peripheral blood of patients with autoimmune hemolytic anemia is closely related to disease evolution, and it has good efficacy in predicting venous thromboembolism and deserves clinical attention.

ABSTRACT

Hepatocellular carcinoma (HCC) has a high recurrence rate after surgical resection. There is little chance for patients with recurrent HCC to receive surgery again, and the main therapy is systemic treatment. However, the efficacy of traditional systemic treatments such as targeted therapy and chemotherapy is limited and the prognosis of patients with advanced HCC is poor. The authors reported a HCC patient who relapsed after surgical resection achieved partial remission with first-line treatment of atelizumab and bevacizumab, according to the latest report of Imbrave150 study. The patient has maintained partial response for more than 1 year, with mild adverse reactions and good efficacy.

ABSTRACT

Hepatocellular carcinoma has a high morbidity and mortality, which has seriously harmed human health. Several targeted therapies have been approved for the first- and second-line treatment of advanced hepatocellular carcinoma. The emergence of immunotherapy has brought the treatment of hepatocellular carcinoma into a new era. Targeted and immunotherapeutic agents have synergistic effects in mechanism, also the combination of these two therapies has been clinically beneficial to patients with advanced hepatocellular carcinoma. At the same time, in addition to the systemic therapy of targeted combined immunological, applying appropriate local therapy can provide a longer survival period or even a chance of cure for that some patients. The authors introduce the diagnosis and treatment of a case of advanced hepatocellular carcinoma who achieved pathological complete remission by first-line immunotherapy combined with anti-angiogenesis targeted therapy.

ABSTRACT

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) catalyze the initial and rate limiting step in the catabolism of tryptophan, which is related to tumor immune tolerance and poor prognosis in patients. In this regard, two enzymes have become important therapeutic targets for tumor immunotherapy. So far, nine IDO1 inhibitors and three IDO1/TDO dual inhibitors have entered clinical trials. This review summarizes the research progress of IDO1 inhibitors, TDO inhibitors and IDO1/TDO dual inhibitors from the perspective of medicinal chemistry.

ABSTRACT

OBJECTIVE:To systematically evaluate the c linical efficacy and safety of misoprostol versus oxytocin in preventing postpartum hemorrhage ,and to provide evidence-based reference for clinical drug use. METHODS :Retrieved from CNKI,VIP,Wanfang database ,CBM,PubMed,Embase and the Cochrane Library ,randomized controlled trials (RCTs) published at home and abroad about clinical efficacy and safety of misoprostol and oxytocin in preventing postpartum hemorrhage were collected during the inception to Feb. 15th,2021. According to the inclusion and exclusion criteria ,the included studies were screened and evaluated. RevMan 5.3 software was used for Meta-analysis. RESULTS :A total of 14 RCTs involving 25 732 lying-in women were included. The results of Meta-analysis showed that compared with oxytocin group ,there was no difference in the mean blood loss (MD=14.96,95%CI(-2.62,32.54),P=0.10),the time of the third stage of labor (MD=-0.03,95%CI (-0.19,0.13),P=0.69),the incidence of blood transfusion (RR=0.91,95%CI(0.74,1.12),P=0.37)or the incidence of nausea(RR=1.06,95%CI(0.85,1.31),P=0.60)in misoprostol group ;but the incidence of shivering(RR=2.99,95%CI (2.22,4.04),P<0.000 01),the incidence of fever (RR=4.31,95%CI(2.79,6.67),P<0.000 01),the incidence of vomiting (RR=2.16,95%CI(1.63,2.88),P<0.000 01)and the incidence of diarrhea (RR=2.67,95%CI(1.79,3.98),P<0.000 01)in misoprostol group were higher. CONCLUSIONS :The effect of misoprostol in the prevention of postpartum hemorrhage is similar to oxytocin ,but the incidence of ADR is higher. It is necessary to pay close attention to the adverse reactions during use. Due to the limitation of included studies ,multi-center,large-scale and high-quality RCTs are needed for further validation.

ABSTRACT

Objective: “Same treatment for different diseases” is a unique treatment strategy in traditional Chinese medicine. Two kinds of malignant respiratory diseases endanger human health-chronic obstructive pulmonary disease (COPD) and lung cancer. Citrus Grandis Exocarpium (Huajuhong in Chinese, HJH), a famous herbal, is always applied by Chinese medicine practitioners to dispersion the lung to resolve phlegm based on “syndrome differentiation and treatment” theory. However, the common mechanism for HJH's treatment of COPD and lung cancer is not clear. Methods: In this study, based on network pharmacology and molecular docking technology, the common mechanism of HJH in the treatment of COPD and lung cancer was studied. The active ingredients and related targets of HJH were integrated from TCMSP, BATMAN-TAM, STP, and Pubchem databases. The standard names of these targets were united by UniProt database. Targets of COPD and lung cancer were enriched through GeneCards, NCBI (Gene), Therapeutic Target Database, and DisGeNET (v7.0) databases. Then the intersection targets of HJH and diseases were obtained. The STRING network and the Cytoscape 3.7.2 were used to construct PPI network, the DAVID database was used to perform GO and KEGG analysis. Then Cytoscape 3.6.1 was used to build “ingredient-target-signal pathway” network. Finally, AutoDock 1.5.6 software was used to perform molecular docking of key proteins and molecules. Results: Eleven active ingredients in HJH were obtained by searching the database, corresponding to 184 HJH-COPD-lung cancer targets intersection. The results of biological network analysis showed that naringenin, the active component in HJH, could mainly act on target proteins such as AKT1, EGFR. Then through positive regulation of vasoconstriction and other biological processes, naringenin could regulate estrogen signaling pathway, VEGF signaling pathway, HIF-1 signaling pathway, ErbB signaling pathway, PI3K-Akt signaling pathway to play an important role in the treatment of both COPD and lung cancer. Conclusion: Network pharmacology was employed to systematically investigate the active ingredients and targets of HJH in treatment of COPD and lung cancer. And then, the common pharmacodynamic network of HJH for the two malignant respiratory diseases was firstly described. Furthermore, naringenin was proved to strongly bind with AKT1 and EGFR. It may provide the scientific basis for understanding the “Same treatment for different diseases” strategy in traditional Chinese medicine and inspirit subsequent drug discovery for COPD, lung cancer and other malignant lung diseases.

ABSTRACT

OBJECTIVE@#To summarize the initial clinical experience and follow-up results of the treatment for ureteroileal anastomotic stricture after radical cystectomy with Allium coated metal ureteral stent.@*METHODS@#From September 2018 to September 2019, 8 patients with ureteroileal anastomotic stricture after radical cystectomy underwent Allium ureteral stent insertion in Peking University People's Hospital and People's Hospital of Daxing District. The preoperative renal pelvis width under ultrasound was collected to evaluate the postoperative hydronephrosis, creatinine and urea nitrogen (BUN) before and after surgery, perioperative infection, and stent-related complications. The serum creatinine and BUN, renal pelvis width under ultrasound, urography and abdominal plain film (KUB) were reviewed at the end of 1, 3, and 6 months and annually postoperatively to observe the stent position and morphology. The long-term stent patency rate, complication rate, renal function and hydronephrosis were followed up and analyzed. The t-test or rank-sum test was used to compare the measurement data of the matched sample from the preoperative to the last follow-up.@*RESULTS@#In the study, 6 cases (7 sides) were ureteral ileal conduit stricture, and 2 cases (3 sides) ureteral orthotopic neobladder stricture. Before surgery, 5 patients underwent long-term indwelling of a single J ureteral stent, with an average indwelling time of (20.6±8.8) months and an average replacement frequency of (3.6±1.3) months/time. The mean width of renal pelvis was (26.5±9.1) mm on preoperative renal ultrasonography. Among them, 6 patients were successfully indwelled with Allium coated metal ureteral stent by retrograde approach, and 2 patients by combination of double-endoscopy and ante-retrograde approach. No surgery-related complications during perioperative period were observed. The mean follow-up period was 9.8 months and Allium stent and ureter remained unobstructed in all the patients at the last follow-up without replacement or removal. Compared with preoperative data, the mean width of renal pelvis and mean blood urea nitrogen (BUN) in the last follow-up period were significantly reduced [(26.5±9.1) mm vs. (13.4±2.5) mm, P=0.008; (11.6±2.3) mmol/L vs. (10.2±2.2) mmol/L, P=0.017], however, there were no significant differences in the average serum creatinine or hemoglobin (P>0.05). Ureteroileal anastomotic re-stricture and other stent-related complications were not observed in all the patients by antegrade urography.@*CONCLUSION@#Allium coated metal ureteral stent could be used for the treatment for ureteroileal anastomotic stricture, which could maintain relatively long-term patency rate and protect renal function. The indwelling time was longer and it could improve quality of life of patients.

ABSTRACT

Objective:To build a medical service experience system based on role play of hospital staff, and explore its contribution to upgrading medical service, elevating medical service quality, and improving patients′ satisfaction.Methods:An indicator system for medical service experience was developed via literature review. 20 newly recruited hospital employees in 2019 were sampled randomly to form a service experience team, who were arranged to experience the full medical service process of outpatients and inpatients based on role play. The questionnaire for service quality based on patient perception and expectation was used to survey the expectation and perception values of those role players on their medical service experiences, and summarize the defects found on such six dimensions as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness. After due corrections of these defects, further experiences and patient satisfaction survey were made to assess the effects of such actions taken. Paired t test was used respectively in statistical analysis of service experience value and actual perception value, as well as the perception values before and after the actions taken, and χ2 test was used for a statistical analysis of patient satisfaction. Results:Role players experienced respectively at the emergency, outpatient and inpatient departments of the hospital for a week in August 2019. Statistics of their experiences indicated≥0.50 points difference between the mean expectation and perception values on doctor-patient communication, patient help responsiveness, outpatient process, examination report delivery duration, service attitude, patient trust on medical workers, medical environment and patient privacy protection.Following a 3-month reform, role players found improvements in such aspects as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness; patient satisfaction improved sizably in December 2019 over January of the same year( P<0.05). Conclusions:The construction and application of the medical service experience system based on role play of hospital staff prove highly useful in upgrading medical service actions, improving medical service quality, and improving patient satisfaction.
