DRG payment reform is an important means to control the unreasonable growth of medical expenses, improve the quality of medical services and achieve a win-win situation among three sides of hospitals, medical insurance and patients. This study adopted the Smith policy implementation process model to analyze the difficulties in the DRG policy implementation process from four aspects(idealized policies, policy implementation institutions, target groups, and policy environment), including the deviation between policy connotations and actual needs; the interest objectives of all parties were not completely aligned, the target group lacked a sense of identity, and the social impact and technological support needed to be improved. It was suggested that optimization should be carried out from four dimensions: policy supply coordination and precision, performance evaluation and personnel literacy, target group cognitive level and participation willingness, and policy implementation environment and atmosphere, in order to synergistically promote the effective implementation of DRG policies.

Background:
Long non-coding RNAs (lncRNAs) have been illustrated to contribute to the development of gestational diabetes mellitus (GDM). In the present study, we aimed to elucidate how lncRNA taurine upregulated gene 1 (TUG1) influences insulin resistance (IR) in a high-fat diet (HFD)-induced mouse model of GDM.
Methods:
We initially developed a mouse model of HFD-induced GDM, from which islet tissues were collected for RNA and protein extraction. Interactions among lncRNA TUG1/microRNA (miR)-328-3p/sterol regulatory element binding protein 2 (SREBP-2) were assessed by dual-luciferase reporter assay. Fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), HOMA pancreatic β-cell function (HOMA-β), insulin sensitivity index for oral glucose tolerance tests (ISOGTT) and insulinogenic index (IGI) levels in mouse serum were measured through conducting gain- and loss-of-function experiments.
Results:
Abundant expression of miR-328 and deficient expression of lncRNA TUG1 and SREBP-2 were characterized in the islet tissues of mice with HFD-induced GDM. LncRNA TUG1 competitively bound to miR-328-3p, which specifically targeted SREBP-2. Either depletion of miR-328-3p or restoration of lncRNA TUG1 and SREBP-2 reduced the FBG, FINS, HOMA-β, and HOMA-IR levels while increasing ISOGTT and IGI levels, promoting the expression of the extracellular signal-regulated kinase (ERK) signaling pathway-related genes, and inhibiting apoptosis of islet cells in GDM mice. Upregulation miR-328-3p reversed the alleviative effects of SREBP-2 and lncRNA TUG1 on IR.
Conclusion
Our study provides evidence that the lncRNA TUG1 may prevent IR following GDM through competitively binding to miR-328-3p and promoting the SREBP-2-mediated ERK signaling pathway inactivation.

Objective:To investigate the methylation status of SDC2, PPP2R5C and ADHFE1 genes in stool and their values in the screening of colorectal cancer and precancerous lesions.Methods:From August 2020 to March 2021, 64 patients with colorectal cancer, 72 patients with adenoma, 33 patients with hyperplastic polyps and 59 healthy people were recruited from Qingdao Central Hospital Affiliated to Qingdao University, and the morning stool samples were collected from the research subjects. The genomic DNA was extracted and modified with sulfite. The methylation status of SDC2, PPP2R5C and ADHFE1 genes were detected by methylation specific polymerase chain reaction (MSP), and the fecal occult blood test (FOBT) was performed. Taking the pathological results as the gold standard, receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to compare the effect of combined detection of methylation of three genes and FOBT in predicting colorectal cancer and precancerous lesions. R-Studio software was used to construct a nomogram for the prediction of colorectal cancer with combined detection of gene methylation in stool and other clinical features, and the calibration and validation were performed.Results:The positive rates of combined detection of methylation of SDC2, PPP2R5C and ADHFE1 genes in stool were higher than those of FOBT in colorectal cancer+adenoma [74.3% (101/136) vs. 47.1% (64/136), χ2 = 23.20, P = 0.001], colorectal cancer [90.6% (58/64) vs. 70.3% (45/64), χ2 = 8.91, P = 0.003] and adenoma [59.7% (43/72) vs. 26.4% (19/72), χ2 = 14.43, P = 0.002]. There was no significant difference in the positive rates in hyperplastic polyps [21.2% (7/33) vs. 6.1% (2/33), χ2 = 0.12, P = 0.125] and healthy controls [10.2% (6/59) vs. 8.5% (5/59), χ2 = 4.01, P = 1.000]. The combined detection of gene methylation was better than FOBT in the prediction of colorectal cancer + adenoma [AUC: 0.85 (95% CI 0.80-0.91) vs. 0.71 (95% CI 0.64-0.78), P < 0.05], especially in the prediction of adenoma [AUC: 0.82 (95% CI 0.74-0.89) vs 0.64 (95% CI 0.57-0.69), P < 0.001]. The sensitivity and specificity of ADHFE1 gene methylation status in predicting colorectal cancer were high (90.6% and 96.6%). In colorectal cancer patients over 50 years old, the positive rate of combined detection of gene methylation was higher than that of FOBT [90.2% (55/61) vs. 68.9% (42/61), P < 0.05]. The nomogram calibration curve for predicting colorectal cancer constructed based on the combined detection of gene methylation and each clinical feature showed a high degree of concordance between the predicted and observed diagnostic performance of colorectal cancer. Conclusions:The methylation levels of SDC2, PPP2R5C AND ADHFE1 genes in stool are increased in patients with colorectal cancer or adenoma. The combined detection of gene methylation is expected to be a non-invasive method for the screening of colorectal cancer and precancerous lesions.

Hederin is a natural active component of triterpenoid saponins extracted from many medicinal herbs, such as Lithospermum erythrorhizon, Pulsatilla chinensis, and Clematis florida. It has attracted much attention from doctors for its anti-inflammatory, anti-convulsive, anti-oxidation and anti-leishmaniasis activities. Hederin has significant anti-tumor bioactivity and is expected to be a potential drug for the treatment of malignant tumors. The available studies have demonstrated that hederin can promote the apoptosis, inhibit the proliferation, metastasis, and invasion, and induce the autophagy of tumor cells, exhibiting a promising prospect in the treatment of breast cancer, lung cancer, liver cancer, and pancreatic cancer. Specifically, hederin can regulate the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway, reactive oxygen species (ROS), and microRNA (miRNA) to trigger tumor cell apoptosis. Its anti-proliferation activity is mainly reflected in the regulation of cyclin and cyclin-dependent kinase (CDK). Hederin inhibits the metastasis and invasion of tumor cells by blocking epithelial-mesenchymal transformation (EMT). In addition, hederin can influence metabolic reprogramming to induce tumor cell autophagy. Hederin is involved in a variety of pathways to exert its anti-tumor activity and may become a novel anti-tumor drug in the future, which give new sights into the study of hederin in the anti-tumor field. There are few studies about hederin and no systematic review of its anti-tumor mechanisms. Therefore, this study reviewed the studies about the anti-tumor mechanism of hederin, aiming to provide reference and information for researchers and clinical staff.

Objective:To explore the effect of problem-based learning (PBL) combined with case teaching method in the three-year probationary teaching of clinical urology in three-year higher vocational colleges.Methods:A total of 45 students from Class 1, Grade 2015, and 37 students from Class 2, Grade 2016 of Ningxia Medical University were selected as study subjects. They were divided into experimental group and control group. Forty-two students in experimental group were taught with PBL combined with case teaching method. 40 students in control group were taught with traditional clinical probation teaching method. Besides, a questionnaire survey was conducted among two groups of students in the Department of urology.Results:There was no significant difference in the scores of theoretical examination between the experimental group and the control group ( P>0.05). The scores of medical history collection, physical examination, practical skills and total scores were much higher in the experimental group than in the control group. The results of the questionnaire survey showed that the teaching of the experimental group could significantly motivate students' enthusiasm and participation, as well as enhance ability of self-study, information acquisition, innovation, analysis and problem-solving and team consciousness ( P<0.05). Conclusion:The new model of PBL combined with case teaching is helpful in improving students' academic performance, probation effect and comprehensive practical ability in urology internship teaching, which is worth being popularized in clinical teaching.

OBJECTIVES:
To investigate the roles of cytoskeleton-associated protein 2 (CKAP2) in proliferation, apoptosis, and migration in liver cancer cells and the potential mechanisms.
METHODS:
Human normal hepatocyte L02 and liver cancer cell lines HepG2, Huh7, and SMMC-7721 were cultured. The CKAP2 expression was detected by real-time PCR and Western blotting. HepG2 cells were randomly divided into a control group, a negative control (NC) group, and a CKAP2 silencing (siCKAP2) group. CCK-8 and BrdU assays were used to evaluate cell viability and proliferation, respectively. Transwell assay was employed to determine cell migration and invasion. The protein levels of cleaved-caspase 3, Bax, E-cadherin, N-cadherin, Vimentin, phosphorylated Janus kinase 2 (p-JAK2), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) were determined by Western blotting.
RESULTS:
Compared with normal hepatocyte L02, CKAP2 was highly expressed in liver cancer cell lines HepG2, Huh7, and SMMC-7721 (all <0.05). Compared with the NC group, cell viability and proliferation rate of the siCKAP2 group were decreased (both <0.05). The apoptotic rate, protein expression of cleaved-caspase 3 and Bax in the siCKAP2 group were significantly higher than those in the NC group (all <0.05). Compared with the NC group, cell migration and invasion rates of the siCKAP2 group were significantly attenuated (both <0.05). Compared with the NC group, E-cadherin protein expression in siCKAP2 group was increased, while protein expression levels of Vimentin, N-cadherin, p-JAK2, and p-STAT3 were decreased (all <0.05).
CONCLUSIONS
CKAP2 gene silence inhibits proliferation, migration, and invasion, and promotes apoptosis in liver cancer cells, while JAK2/STAT3 signaling pathway may be involved in these processes.

OBJECTIVES: Although patients with grade I and II endometrioid endometrial adenocarcinoma (EEA) are considered with good prognosis, among them 15%–25% died in 5 years. It is still unknown whether integrating estrogen receptor (ER) and progesterone receptor (PR) into clinical risk stratification can help select high-risk patients with grade I–II EEA. This study was to investigate the prognostic value of ER and PR double negativity (ER/PR loss) in grade I–II EEA, and the association between ER/PR loss and The Cancer Genome Atlas (TCGA) classification. METHODS: ER and PR were assessed by immunohistochemistry on hysterectomy specimens of 903 patients with grade I–II EEA. ER and PR negativity were determined when < 1% tumor nuclei were stained. Gene expression data were obtained from the TCGA research network. RESULTS: Compared with ER or PR positive patients (n=868), patients with ER/PR loss (n=35) had deeper myometrial infiltration (p=0.012), severer FIGO stage (p=0.004), and higher rate of pelvic lymph node metastasis (p=0.020). In univariate analysis, ER/PR loss correlated with a shorter progression-free survival (PFS; hazard ratio [HR]=5.25; 95% confidence interval [CI]=2.21–12.52) and overall survival (OS; HR=7.59; 95% CI=2.55–22.60). In multivariate analysis, ER/PR loss independently predicted poor PFS (HR=3.77; 95% CI=1.60–10.14) and OS (HR=5.56; 95% CI=1.37–22.55) for all patients, and poor PFS for patients in stage IA (n=695; HR=5.54; 95% CI=1.28–23.89) and stage II–IV (n=129; HR=5.77; 95% CI=1.57–21.27). No association was found between ER/PR loss and TCGA classification. CONCLUSION: Integrating ER/PR evaluation into clinical risk stratification may improve prognosis for grade I–II EEA patients.

OBJECTIVE: To investigate the potential effective components and mechanism of Achyranthes bidentata in the treatment of osteoporosis (OP). METHODS: The effective components of A. bidentata were retrieved from the TCMSP database, and corresponding targets of them were collected. The targets related to OP were retrieved from DisGeNET database. TBtools 1.0 mapping software was used to draw the Wayne diagram, and screen the intersecting targets of effective components of A. bidentata and disease OP. Cytoscape 3.6.1 software and STRING database were used to construct and analyze the “drug-component- disease-target” network and protein-protein interaction (PPI) network; KEGG pathway enrichment analysis was conducted by using DAVID bioinformatics resource database. RESULTS: A total of 19 effective components were screened from A. bidentata, and there were 32 intersecting targets between effective components and disease OP. In “drug-component-disease-target” network, there were 45 nodes [1 for A. bidentata, 1 for OP, 11 for effective components (8 of the 19 effective components had no corresponding OP target), 32 for intersecting targets] and 119 edges between nodes; quercetin, kaempferol, wogonin, baicalein and palmatine were important effective components. In PPI network, there were 31 nodes (1 of 32 intersecting targets was not associated with other proteins) and 212 edges, among which IL6, ESR1, MAPK1, IL8 and MAPK14 were the core targets of the network. There were 67 KEGG enrichment pathways, including rheumatoid arthritis, hepatitis B, Toll-like receptor signaling pathway, PI3K/Akt signaling pathway, JAK/STAT signaling pathway, NF-κB signaling pathway and so on. CONCLUSIONS: The main potential effective components of A. bidentata in the treatment of OP are quercetin, kaempferol, wogonin, baicalein and palmatine, the mechanism of which may be associated with cell differentiation and apoptosis, metabolism, inflammation reaction, etc. It has multi-component, multi-target and multi-system chara- cteristics.

OBJECTIVE: Our previous study showed that insulin resistance (IR) was related to endometrial hyperplasia as well as endometrial cancer. But the exact impact of IR on fertility-sparing treatment in endometrial hyperplasic disease is unclear. This study investigated how IR affects fertility-sparing treatment in endometrial atypical hyperplasia (EAH) patients. METHODS: The 151 EAH patients received fertility-sparing treatment were retrospectively investigated. All patients received high-dose progestin combined with hysteroscopy. Therapeutic effects were evaluated by hysteroscopy every 3 months during the treatment. RESULTS: The median age was 33.0 years old (range, 21–54 years old). Sixty-one patients (40.4%) were insulin resistant. Three patients were excluded from the analysis because they chose hysterectomy within 3 months after initiation of progestin treatment. The 141 out of 148 (95.3%) patients achieved complete response (CR). No difference was found in cumulative CR rate between those with or without IR (90.2% vs. 95.6%, p=0.320). IR significantly affected therapeutic duration to achieve CR (8.1±0.5 months with IR vs. 6.1±0.4 months without IR, p=0.004). Overweight (body mass index [BMI]≥25 kg/m2) was associated with higher risk of treatment failure (odds ratio=5.61; 95% confidence interval=1.11–28.35; p=0.040) and longer therapeutic duration to achieve CR (7.6±0.5 months vs. 6.3±0.4 months, p=0.019). EAH patients with both IR and overweight (IR+BMI+) had the longest therapeutic time compared with other patients (8.8±0.6 months vs. 5.6±0.7, 6.3±0.4, and 6.4±0.8 months for IR−BMI+, IR−BMI−, and IR+BMI−, respectively, p=0.006). CONCLUSION: IR and overweight were associated with longer therapeutic duration in EAH patients receiving progestin-based fertility-sparing treatment.
