Objective:To develop employer's satisfaction evaluation index system towards post competency of residents.Methods:Using Delphi method, the employer's satisfaction evaluation index system towards post competency of residents was formulated through a two-round expert consultation among 19 experts. SPSS 20.0 was used for statistical analysis to calculate the positive coefficient, authority coefficient and coordination degree of experts.Results:For the two rounds of the expert consultation, the questionnaire recovery rate was 95.0% and 100% respectively. The experts' authority coefficient was 0.92, and the system was ultimately determined, including 5 first-level indicators, and 32 secondary indicators. The coefficient of variation (CV) of first-level indicators was 0.00, and the Kendall's W of secondary indicators was 0.663. Conclusions:Employer's satisfaction evaluation index system towards post competency of residents is scientific and reliable, which could provide employer with systematic and objective tool to evaluate residents' post competency.

Objective:To investigate the efficacy of the plan-do-check-action (PDCA) quality circle in improving the ability for teaching rounds among clinical mentors, and to enhance the construction of teaching staff and the quality of teaching rounds.Methods:The hospital-level assessment scores of the ability for teaching rounds were collected from 34 clinical mentors in different clinical departments of Zhongnan Hospital of Wuhan University in 2021, and such data were used to investigate the influencing factors for the quality of teaching rounds. Then a PDCA plan was developed and executed to improve the quality of teaching rounds. After the implementation of this plan, hospital-level assessment of the ability for teaching rounds was performed for 34 clinical mentors who were randomly selected from different clinical departments in 2022. The 34 clinical mentors who received the hospital-level assessment of the ability for teaching rounds in 2021 were enrolled as control group, and the 34 clinical mentors who received such assessment in 2022 were enrolled as experimental group. The assessment scores were compared between the two groups to evaluate the implementation effect of PDCA, and SPSS 20.0 was used for data analysis. Categorical data were expressed as number of cases or percentage and were analyzed using the chi-square test, and continuous data were expressed as mean±standard deviation and were analyzed using the t-test. Results:Assessment indices included the preparation, execution, skills, and overall impression of teaching rounds. After the implementation of PDCA, there was a significant increase in the excellence rate of assessment scores (76.47% vs. 50.00%) and a significant reduction in the unqualified rate of assessment scores (2.94% vs. 20.59%), with a significant difference ( P=0.031). There was a tendency of increase in the scoring rates of ward round execution (83.44% vs. 88.26%), ward round skills (82.60% vs. 91.09%), and overall impression (90.20% vs. 93.63%), and there were also significant increases in the scores of ward round skills [(14.87±3.02) vs. (16.40±1.53), P=0.020], improvement of the clinical thinking abilities of trainees through diagnosis and differential diagnosis [(7.96±1.66) vs. (8.93±0.93), P=0.006], guidance for trainees to formulate reasonable diagnosis and treatment regimens [(4.18±1.11) vs. (4.82±0.47), P=0.005], and emphasis on key and challenging points in the teaching process [(3.01±0.76) vs. (3.97±0.17), P<0.001]. Conclusions:The application of PDCA can improve the performance of clinical mentors in the process of teaching rounds, enhance their ability for teaching rounds, fortify the team construction of clinical mentors, and help to improve the quality of teaching rounds.

Myositis antibodies are divided into myositis-specific autoantibodies(MSA)and myositis-associated autoantibodies(MAA).There are heterogeneity in the mechanism,clinical features and prognosis of interstitial lung disease(ILD)in the different myositis antibodies.In MSA,anti-melanoma differentiation-related gene 5(MDA5)antibody and anti-aminoacyl synthetase(ARS)antibody are highly correlated with the occurrence of ILD.Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis.The progress of ILD in ARS+DM patients was slow,and the response to treatment is good,but it is easy to relapse.In MAA,anti-Ro52 antibodies often coexist with MSA antibodies,and clinical manifestation is closely related to coexisting antibodies.This review has summarized roles of myositis antibodies in ILD.

OBJECTIVE To evaluate the mechanisms underlying the antidepressant effect of ZBH2012001,a novel serotonin and norepinephrine reuptake inhibitor(SNRI),in general and its ability to enhance monoaminergic transmission and suppress neuroinflammation in particular.METHODS① Male ICR mice were divided into vehicle(distilled water),duloxetine(DLX,10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following ig administration,the antidepressant effect of ZBH2012001 was evaluated using the tail suspension test(TST)and forced swimming test(FST).② Radioligand binding assay was conducted to evaluate the affinity of ZBH2012001 for human serotonin transporters(hSERTs)and human norepinephrine transporters(hNETs).③ Mice were divided into vehicle(distilled water),DLX(10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following drug administration,the 5-hydroxytryptophan(5-HTP)-induced head-twitch test or yohimbine-induced lethality test were performed to evaluate the effect of ZBH2012001 on the function of the 5-hydroxytryptamine(5-HT)and norepinephrine(NE)systems.④ Mice were divided into vehicle(distilled water+0.1%acetic acid),reserpine model(distilled water+reserpine 5 mg·kg-1),DLX(DLX 20 mg·kg-1+reserpine 5 mg·kg-1)and ZBH2012001(ZBH2012001 5,10 and 20 mg·kg-1+reserpine 5 mg·kg-1)groups.One hour following drug administration,reserpine was injected intraperitoneally to establish a monoamine-depletion model.The ptosis,akinesia,and hypothermia assays were performed to evaluate the effect of ZBH2012001 on the down-regulation of the reserpine-induced monoamine system.The TST in mice was used to evaluate the effect of ZBH2012001 on reserpine-induced depressive-like behavior while high-performance liquid chromatography with electrochemical detection(HPLC-ECD)was used to measure the levels of monoamines and their metabolites in the hippocampal tissue of reserpine-induced monoamine-depletion mice.ELISA was employed to detect the contents of tumor necrosis factor-alpha(TNF-α)and interleukin-6(IL-6)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.Western blotting was used to assess the expressions of ionized calcium-binding adapter molecule-1(Iba-1)and nuclear factor-kappa B(NF-κB)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.RESULTS ① Compared with the vehicle group,ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the immobility time both in the TST in mice(P<0.01,respectively),and ZBH2012001(20 mg·kg-1)and in the FST in mice(P<0.05).② ZBH2012001 competitively inhibited the binding of[3H]-imipramine to hSERTs and[3H]-nisoxetine to hNETs,with the half maximal inhibitory concentration(IC50)values of 84.95 and 712.90 nmol·L-1,respectively.③Com-pared with the vehicle group,ZBH2012001(10 and 20 mg·kg-1)significantly increased the head twitches induced by 5-HTP in mice(P<0.01,respectively)and increased the mortality rate in mice induced by yohimbine(P<0.05,P<0.01).④ In the reserpine-induced monoamine-depletion model in mice,compared with the vehicle group,mice in the reserpine model group exhibited ptosis,akinesia and hypothermia feature(P<0.01,respectively),significantly prolonged immobility time in the TST(P<0.01),significantly decreased the levels of NE,5-HT and dopamine(DA)(P<0.05,P<0.01),significantly increased the metabolic conversion rate of 5-HT and DA(P<0.01,respectively),significantly elevated levels of TNF-α and IL-6(P<0.05,respectively),and significantly increased expressions of Iba-1 and NF-κB(P<0.05,respectively)in the hippocampus.Compared with the model group,ZBH2012001(5,10 and 20 mg·kg-1)significantly antagonized ptosis and hypothermia behaviors induced by reserpine(P<0.01,respectively),ZBH2012001(10 and 20 mg·kg-1)significantly shortened the immobility time in reserpine-treated mice(P<0.05,P<0.01),ZBH2012001(20 mg·kg-1)significantly increased the levels of NE and 5-HT in the hippocampus of reserpine-treated mice(P<0.05,respectively),decreased the metabolic conversion rate of 5-HT(P<0.05),significantly reduced the contents of TNF-α and IL-6 in the hippocampus of reserpine-treated mice(P<0.05,respectively),ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the expression of Iba-1 protein in the hippocampus of reserpine-treated mice(P<0.01,respec-tively),and ZBH2012001(20 mg·kg-1)significantly reduced the expression of NF-κB protein in the hippocampus of reserpine-treated mice(P<0.05).CONCLUSION ZBH2012001 exerts its antidepres-sant effect through a dual mechanism involving monoamine enhancement and inflammation suppres-sion.

Objective:To explore the application of games combined with speech training in rehabilitation care for language development retardation in high-risk children aged 2 to 5 years.Methods:Totally 190 high-risk children aged 2 to 5 years with language development retardation admitted from January 2016 to December 2018 in Luzhou People's Hospital were selected by convenient sampling, and divided into observation group ( n=95) and control group ( n=95) according to the random number table. Children in the control group received conventional speech training, while children in the observation group received speech training combined with games for 6 months. The effects of rehabilitation training were observed in the two groups, and the speech development quotient of the children was evaluated using the Gesell Developmental Schedules (GDS) . The satisfaction rate to rehabilitation of parents of two groups were compared. Results:After 6 months of training, the effective rates of rehabilitation training were 86.32% (82/95) in the observation group and 73.68% (70/95) in the control group, and the difference was statistically significant ( P<0.05) . The GDS scores were (60.36±8.25) in the observation group and (56.67 ± 7.84) in the control group, and the difference was statistically significant ( P<0.05) . The satisfaction rate of parents of children in the observation group on rehabilitation effect, service attitude, professional skills, and humane care were higher than those in the control group, and the differences between the two groups were statistically significant ( P<0.05) . Conclusions:In high-risk children aged 2 to 5 years with language development retardation, speech training combined with games can improve children's speech development quotient and promote their rehabilitation.

Objective To summarize the first experience with ultrasound-guided percutaneous ab lation treatment (PAT) for recurrent hepatoblastoma (HB) after liver resection in children.Methods From August 2013 to April 2015,PAT was used to treat 6 children with a total of 9 recurrent HB,including 5 patients with 8 tumors in the liver and 1 patient with 1 tumor in the lung.The mean size of ablated tumors was (1.5 ± 0.8) cm,and the tumor size range was 0.7 cm to 3.1 cm.Results Four patients were performed percutaneous radiofrequency ablation (RFA) for recurrent HB;and 2 patients were performed percutaneous ethanol injection (PEI).Ablation success was achieved in all patients (6/6,100％).The complete ablation rate after the first ablation session was 88.9％ (8/9) on a tumor-by-tumor basis.Only 1 patient developed a fever with temperature ＞ 39 ℃;it was resolved by conservative therapy.During the follow-up period of 5-30 months,3 patients died to tumor progression.The 1-and 2-year overall survival rates after ablation were 83.3％ and 41.7％,respectively.Conclusions PAT is a safe and promising therapy for children with recurrent HB after liver resection,and further investigation in large-scale randomized clinical trials is required to determine its role in the treatment of this disease.

OBJECTIVETo study the mechanism that mediates the therapeutic effect of the bioactive fraction of Baqia (Smilax china) on chronic pelvic inflammatory disease (CPID).

METHODSSeventy rats were randomized into CPID model group, sham-operated group, normal control group, Jingangteng capsule group, and high-, medium-, and low-dose Baqia groups. Rat models of CPID were established by inducing chemical burns of the uterus and corresponding treatments were administered. After 14 days of treatment, the rat uterus was observed for swelling and inhibition rate, and the expressions of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) in the uterine tissues were determined using enzyme-linked immunosorbent assay.

RESULTSThe bioactive fraction of Baqia at the 3 doses obviously reduced the inflammatory cells in the endometrium, promoted epithelial cell proliferation, and ameliorated congestion and edema of the serosa. High and medium doses of Baqia bioactive fraction significantly decreased uterus swelling rate of the rats (P<0.01). All the 3 doses of the Baqia bioactive fraction obviously decreased uterine TNF-α content (P<0.01) and significantly increased uterine IL-4 expression level (P<0.05), and IL-4 up-regulation was especially obvious in high and medium dose groups (P<0.01).

CONCLUSIONBaqia bioactive fraction can ameliorate uterine swelling, lower uterine TNF-α and increase IL-4 expressions in rats with CPID, which may be a pharmacological mechanism underlying its therapeutic effect on CPID and cervical adhesion.
