Objective To learn the present financial staffing at public hospitals in detail,for development of a staffing standard of financial workers at public hospitals.Methods The headcount of financial workers at all tertiary hospitals in China was counted.The correlation between the number of financial workers and the overall size of the hospital was analyzed using SPSS 19.0 software to develop a data model.Results Data analysis showed that the assets,revenue/expenditure,hospital beds,workload,and staff headcount of a hospital are in linear co-relation with the headcount of its financial workers (P ＜ 0.001),and presented a curve that the number of hospital financial workers will vary with the factor of the hospital's overall size.Conclusions The number of hospital financial workers is closely related to the size of the hospital,and the curve can help estimate the number of financial workers of the hospital.

Objective: To investigate the serum levels and clinical significances of microRNA-205 (miR-205) and microRNA-221 (miR-221) in patients with colon cancer. Methods: A total of 172 patients with colon cancer (colon cancer group), 130 patients with benign diseases of colon (benign lesion group) and 70 healthy persons (control group) admitted to Central Hospital of Western Hainan from January 2016 to December 2018 were selected. The serum levels of miR-205 and miR-221 in each group were detected, and their relationships with clinicopathological characteristics of patients with colon cancer were analyzed. The diagnostic values of the serum levels of miR-205 and miR-221 in colon cancer were analyzed by receiver operating characteristic (ROC) curve. Pearson correlation analysis was used to analyze the correlation between the serum levels of miR-205 and miR-221. Results: The serum levels of miR-205 in colon cancer group, benign lesion group and control group were 2.84±0.96, 1.16±0.27 and 1.05±0.23, with a statistically significant diffe-rence (F=10.113, P<0.001). The serum levels of miR-221 in the three groups were 1.95±0.74, 0.37±0.08 and 0.32±0.05, with a statistically significant difference (F=12.416, P<0.001). Further pairwise comparisons found that the serum levels of miR-205 and miR-221 in colon cancer group were significantly higher than those in benign lesion group and control group (all P<0.001). The serum levels of miR-205 and miR-221 in patients with colon cancer were related with TNM stage (t=5.412, P<0.001; t=6.103, P<0.001), degree of tumor differentiation (t=4.573, P=0.028; t=4.805, P=0.013) and with or without lymph node metastasis (t=5.837, P<0.001; t=7.410, P<0.001). ROC curve analysis showed that the optimal cut-off values of the serum levels of miR-205 and miR-221 for the diagnosis of colon cancer were 2.17 and 1.30, respectively. The area under the curve of the two combined diagnostic method for colon cancer was the largest (0.924, 95%CI: 0.865-0.983), with the sensitivity and specificity of 91.3% and 87.4%. The correlation analysis showed that the serum levels of miR-205 and miR-221 were positively correlated in patients with colon cancer (r=0.837, P<0.001). Conclusion The serum levels of miR-205 and miR-221 are significantly increased in patients with colon cancer, and the two combined detection has a high value for the diagnosis of colon cancer.

With the resource based relative value scale (RBRVS) application at a hospital cited as an example, the paper covered its use in performance appraisal for optimal performance-based distribution as follows. In view of hospital specifics, such appraisal indexes as the quantity, quality, technical difficulty and cost control are quantified as key indicators, to form its own RBRVS scores and weights. In combination of the case mixed index as well, such factors as specific appraisal, quality of care and research/teaching work are taken into account for the purpose of rational and optimal pay for performance.

Objective To learn the initial application of RBRVS related performance appraisal at public hospitals in China. Methods 12 tertiary public hospitals which took the lead to introduce RBRVS models, via third-party cooperation, in medical stuff performance assessment over one year were surveyed. The study summarized their design emphases of RBRVS performance appraisal, covering such aspects as appraisal level, accounting method, conceptual design, points setup and items charged as cost. Descriptive statistics was used to analyze the data so acquired. Results As shown in the performance appraisal level, most hospitals were found with defects in refining levels, as eight hospitals only appraise down to the department level, three to diagnostic group level, and only one hospital to individuals. Of these hospitals, over eight hospitals used RBRVS to elevate the efficiency and inventiveness of employees, while half of these hospitals reported the method can improve service, reduce cost and enhance quality of care. Conclusions Public hospitals enjoy advantages via third-party cooperation RVRBS method in RVRBS-related reforms. Introduction of this method calls for localization design based specifics and management goals of public hospitals.

Objective To observe the effects of different ligation sites and fasting method on a C57BL/6J mouse model of partial bile duct ligation(pBDL)-induced cholestasis,to establish a pBDL modeling method with a high modeling rate,typical symptoms,and good stability.Methods C57BL/6J mice were subjected to selective ligation of the left hepatic bile duct(L-pBDL)and left-to-median bile duct junction ligation(ML-pBDL)for modeling,and the effects of different pBDL ligation method on serum alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase(ALP),total bilirubin,total bile acid,and liver histopathology were observed.The effects of different fasting method on symptoms and liver injury in the ML-pBDL model were also observed after fasting for 12 and 16 h before surgery,and for 4 h after surgery.Results(1)The incidence of jaundice in the ML-pBDL group was 52.94%and the survival rate within 3 weeks after surgery was 64.71%,while the incidence of jaundice in the L-pBDL group was 11.76%and the survival rate within 3 weeks after surgery was 82.35%.Compared with those in the sham surgery group,serum liver function indicators were significantly increased in the L-pBDL and ML-pBDL groups(P＜0.01),and ALP activity was significantly higher in the ML-pBDL group than in the L-pBDL group(P＜0.05).Compared with mice in the L-pBDL group,mice in the ML-pBDL group had more severe liver fibrosis at 3 weeks post-surgery(P＜0.01).(2)In addition,the incidence of jaundice in the 16 h fasting group was 93.33%and the survival rate within 3 weeks after surgery was 73.77%,while the incidence of jaundice in the 12 h fasting group was 42.86%and the survival rate within 3 weeks after surgery was 71.42%.Compared with those in the normal group,ALP activity,alanine aminotransferase/aspartate aminotransferase ratio,total bile acid level,and proportion of collagen fiber area were all significantly increased in the 16 h and 12 h fasting groups(P＜0.05).Although the observed indicators were higher in the 16 h fasting group compared with those in the 12 h fasting group,the difference was not significant(P＞0.05).Mice in the 12 h and 16 h fasting groups both showed significant bile duct hyperplasia and liver fibrosis(P＜0.01),with more severe liver fibrosis in the 16 h fasting group(P＜0.01).Conclusions Both L-pBDL and ML-pBDL ligation method can be used to establish a mouse model of cholestasis;however,symptoms in the L-pBDL model only exhibit transient damage characteristics,while the liver lesions in the ML-pBDL model are typical and stable.Prolonging the preoperative fasting time can improve the modeling rate and stability of the ML-pBDL model and produce more-typical pathological symptoms.

N 6-methyladenosine (m 6A) modification can regulate gene expression by influencing RNA stability, nuclear transport, translation efficiency, alternative splicing and degradation. Current studies have shown that m 6A modification is associated with multiple biological behaviors of melanoma, such as proliferation, metastasis and resistance to immunotherapy, but specific mechanisms still need further study. This review summarizes the regulation of m 6A RNA methylation, and its related biological behaviors and mechanisms of action in melanoma.

Objective:To investigate whether long non-coding RNA(lncRNA) AW112010 can improve insulin resistance in aging adipocytes through the miR-204/POU2F2 signaling pathway.Methods:In vivo experiment: C57BL/6 mice were divided into young control group(4 months old) and aging model group(18 months old) based on body weight. The expression levels of AW112010, miR-204-5p, POU2F2, aging related indicators(p16, p21), and insulin signaling pathway genes [insulin receptor(INSR), insulin receptor substrate 1(IRS1), phosphatidylinositol kinase(PI3K), protein kinase B(AKT)] in epididymal adipose tissue were detected using real-time fluorescence quantitative PCR(RT-qPCR) and Western blotting. In vitro experiment: Using adriamycin(ADR) to induce 3T3-L1 aging adipocyte model, β-gal staining was used to observe cellular senescence, and miR-204 inhibitor and miR-204 mimic small interfering RNA were successfully constructed and transfected into 3T3-L1 adipocytes. Results:RT-qPCR and Western blot results showed that compared with the young group, the expression of AW112010 in the adipose tissue of aging mice was increased, while the expression of miR-204-5p was decreased. The expressions of POU2F2, p16, and p21 in the adipose tissue of aging mice were increased, while the expressions of INSR, IRS1, PI3K, GLUT4 mRNA and protein were decreased. The β-gal stainging results showed that the number of 3T3-L1 senescent adipocytes induced by ADR was significantly increased, and the expression levels of AW112010, POU2F2, p16, and p21 in ADR-induced senescent adipocytes were increased compared with the control group, while the expression levels of miR-204-5p, INSR, IRS1, PI3K, GLUT4 were decreased, and remaining glucose in the culture medium was increased. Compared with control, overexpression of miR-204 resulted in decreased expressions of aging indicators p16, p21, and target gene POU2F2 while the expressions of INSR and GLUT4 were increased.Conclusion:Upregulation of lncRNA AW112010 in adipocytes of aging mice may induce insulin resistance by targeting miR-204-5p/POU2F2/IRS1.

Uric acid (UA), the final product of human purine metabolism, can cause hyperuricemia (HUA) when excessively accumulated. HUA is closely linked to chronic kidney diseases (CKD) and is considered an independent risk factor. Hyperuricemic nephropathy, a form of CKD induced by HUA, has seen significant advances in understanding through research into the pathogenic roles of uric acid and the development of HUA animal models. Although progress has been made in understanding the pathophysiological mechanisms by which UA induces CKD, much remains to be learned about its pathological molecular mechanisms. New approaches in animal modeling or the selection of model animals may potentially lead to significant breakthroughs in research on hyperuricemia as well as related CKD. This paper reviews the research progress on the molecular mechanisms of hyperuricemic nephropathy, focusing on oxidative stress, inflammation, autophagy, fibrosis, and gut microbiota. Oxidative stress is induced by uric acid intracellularly through xanthine oxidase, NADPH oxidases, and mitochondria, leading to cellular damage. In terms of inflammation, uric acid crystals can activate the NLRP3 inflammasome, triggering an inflammatory cascade. The role of free uric acid as a pro-inflammatory agent, however, remains controversial. Depending on the study conducted, autophagy has been found to either alleviate or exacerbate inflammation induced by uric acid. Fibrosis, particularly through epithelial-mesenchymal transition (EMT), is a major mechanism by which uric acid causes glomerulosclerosis and tubulointerstitial fibrosis. Extensive research has explored various signaling pathways involved in uric acid-induced EMT. Beneficial gut microbiota protect the kidneys by synthesizing short-chain fatty acids, reducing urea’s enterohepatic circulation, and decreasing uric acid production. This paper aims to enhance understanding of the complex relationships between HUA and CKD, serving as a reference for further research and new drug development.

The formulation method of emergency health systems guidance （HSG） is crucial， directly impacting the efficiency and effectiveness of responses in emergencies. A scientifically sound， systematic， and easily executable guidance document can assist health institutions at all levels in quickly coordinating resources， standardizing emergency response processes， and safeguarding public health. This study employed the Appraisal of Guidelines for Research and Evaluation for Health Systems （AGREE-HS） to analyze the characteristics of participants in developing emergency HSGs represented by the COVID-19 emergency HSG. The results showed that in the 34 HSGs included in this study， the item participants received the lowest score. Within this item， criterion 1 （diversity of development group） scored the highest （3.13±1.55）， while criterion 5 （prevention of funding agency influence） scored the lowest （1.21±0.47）. There were differences （P<0.05） in measures taken to mitigate funding agency influence between the six standard HSGs developed by the World Health Organization （WHO） and the four emergency HSGs. Additionally， differences （P<0.05） existed in the development group members， background， conflicts of interest， and preventive measures between the six WHO standard HSGs and the 34 emergency HSGs， as well as between the HSGs developed by the WHO and those developed by countries. The participants in developing emergency HSGs were influenced by various factors， including limited time for guideline development， modes of participation， scarce evidence， and uncertainties in expected outcomes. There is a need to downplay extensive requirements concerning the composition of group members， institutional diversity， and conflicts of interest， emphasizing the roles of key participants like government officials and professionals who can provide rapid， practical guidance in emergency situations.

Recommendations， consensus-based syntheses of the best available evidence， constitute the core content of a guideline. This paper analyzes the characteristics of emergency health systems guidance documents （HSGs）， represented by the coronavirus disease-2019 （COVID-19） emergency HSG， regarding the item "recommendations" and its eight evaluation criteria in the Appraisal of Guidelines for Research and Evaluation for Health Systems （AGREE-HS）. The World Health Organization （WHO） standard HSGs were used as reference to explore the characteristics of emergency HSGs that are different from non-emergency HSGs. The results showed that the “recommendations” scored second after “topic” among the five items. Criterion 7 relating to operability scored higher than others among the eight criteria， and criterion 3 dealing with ethical principles scored lower than other criteria. Compared with the standard HSGs， the emergency HSGs showed decreased scores （P<0.05） of the item recommendations and the criteria of this item except criterion 4 concerning equity promotion. Among the HSGs with different developers， those developed by the WHO had higher （P<0.05） scores of recommendations than nationally developed HSGs， as evidenced by criterion 4， criterion 5 involving acceptability to and alignment with sociocultural and political interests， and criterion 8 for updating plans. The HSGs regarding global or country strategy scored higher （P<0.05） on criterion 2 relating to comprehensiveness than those involving specific guidance on clinical or material issues. Overall， the emergency HSGs， represented by the COVID-19 emergency HSGs， differ from the standard HSGs in a number of ways in terms of their recommendations. Emergency HSGs have more condensed content and weaker articulation of expected outcomes. They incline to put more emphasis on updating plans， rather than comprehensiveness or integrative requirements in terms of ethics， equity， and sociocultural and political interests.
