To synthesize salbutamol immunogen and develop an enzyme immunoassay (ELISA), a new salbutamol immunogen was synthesized using 4-aminobenzoic acid as a linker to connect hapten with carrier protein. An enzyme immunoassay based on the antibody prepared was developed and applied to detect salbutamol residue spiked in swine liver. An unusual coating antigen, clenbuterol-ovalbumin (OVA) conjugate instead of salbutamol-OVA conjugate, was used in the immunoassay and the results were discussed based on the structures of related compounds. The antibodies showed high sensitivity in the heterologous assay when using clenbuterol-OVA as a coating antigen, with an IC50 value of 8.97 ng mL(-1) toward salbutamol. The antibodies prepared showed high cross-reactivity with clenbuterol (107%) and were promising for the simultaneous determination of salbutamol and clenbuterol residues in food and food products. Recovery rates from the salbutamol-spiked swine liver samples were in the range of 70%-99%, while the intra-assay and inter-assay coefficients of variation were <13.3% and <14.3%, respectively. In summary, the antibodies of salbutamol have been successfully prepared. Sensitive and stable analysis for the detection of salbutamol residues in swine liver was obtained based on the competitive ELISA methods developed in this study.

Objective:To explore the molecular genetics of myeloid neoplasms in elderly patients.Methods:High-throughput DNA sequencing was performed to detect 49 target gene mutations in 26 patients with acute myeloid leukemia(AML)and 51 patients with myelodysplastic syndrome(MDS). Genomic DNA-PCR and Sanger sequencing were used to detect the mutations of CALR gene exon 9, NMP1 gene exon 12, FLT3-ITD and the two functional domains, TAD and BZIP, in CEBPA.Results:(1)Of the 77 patients enrolled, the overall incidence of gene mutations was 91.0%(71/77), with an average of 2 mutations per patient and an incidence of 42.9% for the coexistence of 3 or more gene mutations(33/77), and the most common genetic mutations were NPM1, U2AF1, RUNX1, TET2, ASXL1, TP53, DNMT3A, IDH2, BCOR, and FLT3-ITD, and the incidence of other genetic mutations was<10%.(2)The incidence of double gene mutations in the AML group was significantly higher than that in the MDS group, and the incidence of≥3 gene mutations in the MDS group was higher than that in the AML group( P<0.05). The AML group was associated with significantly higher incidences of NPM1, FLT3-ITD, and CEBPA double mutations and lower incidences of BCOR and ASXL1 mutations than those in the MDS group(all P<0.05). Functional classification showed that tyrosine kinase receptor gene mutations mainly occurred in the AML group( P=0.004), while chromatin modified gene mutations mainly occurred in the MDS group( P=0.007). (3)Fifty-one cases with MDS were followed up and 9 cases developed leukemia transformation with an average transformation time of 6.5 months during the period, and the conversion rate of patients with RUNX1 and U2AF1 mutations was 44.4%, which was higher than that of other gene mutations. Conclusions:Elderly patients with myeloid neoplasms have unique gene mutation profiles.The types and frequencies of common myeloid tumor gene mutations are different in AML and MDS, and some gene mutations in patients with MDS are related to leukemia transformation.

Testamentary capacity is one of the civil competences, it means that a natural person enjoys the capacity or qualification to establish testament and deal with his property. Recently, the cases of testamentary capacity assessment of the mentally disordered are increasing. This article firstly introduces the concepts of the testament as well as the testamentary capacity, and then summarizes the assessment standard of the testamentary capacity, by using the Banks v. Goodfellow case as a basis to make the standard criteria including: the understanding of the nature of a will and codicil, the knowledge of the general extent of one's assets, the knowledge of the natural object of one's bounty, the understanding of the impact of the distribution of the assets of the estate, and the absence of a delusion specifically affecting the distribution of the estate. The impact factors of the testamentary capacity, including dementia, mood disorder, schizophrenia, alcohol, drug, and undue influence, etc., are summarized. Lastly, the related assessment tools such as the Mini-Mental State Examination, the Clock-Drawing Test, and the Testament Definition Scale are introduced briefly.

PURPOSE:
The International Study Group on Pancreatic Fistula's definition of postoperative pancreatic fistula (POPF) has recently been updated. This study aimed to identify risk factors for POPF in patients having pancreaticoduodenectomy (PD) and to generate a nomogram to predict POPF.
METHODS:
Data on 298 patients who underwent PD from March 2012 to October 2017 was retrospectively reviewed and POPF statuses were redefined. A nomogram was constructed using data from 220 patients and validated using the remaining 78 patients. Independent risk factors for POPF were identified using univariate and multivariate analyses. A predictive nomogram was established based on the independent risk factors and was compared with existing models.
RESULTS:
Texture of the pancreas, size of the main pancreatic duct, portal vein invasion, and definitive pathology were the identified risk factors. The nomogram had a C-index of 0.793 and was internally validated. The nomogram performed better (C-index of 0.816) than the other most cited models (C-indexes of 0.728 and 0.735) in the validation cohort. In addition, the nomogram can assign patients into low- (less than 10%), intermediate- (10% to 30%), and high-risk (equal or higher than 30%) groups to facilitate personalized management.
CONCLUSION
The nomogram accurately predicted POPF in patients having PD.

OBJECTIVE:
To evaluate the comprehensive technical efficiency of the tertiary public hospitals in Beijing between 2006 and 2015 and explore its influencing factors, so as to propose corresponding policy suggestions.
METHODS:
The data envelopment analysis was employed to evaluate the comprehensive technical efficiency, pure technical efficiency and scale efficiency of the tertiary public hospitals in Beijing. Malmquist index model was used to analyze the changes of the above three dynamic efficiencies. Finally, randomeffect panel tobit model was utilized to analyze the influencing factors of the comprehensive technical efficiency.
RESULTS:
The average comprehensive technical efficiency and pure technical efficiency of the tertiary public hospitals in Beijing were relatively high, and they had respectively increased from 0.44 and 0.51 in 2006 to 0.62 and 0.68 in 2015, and the highest proportion of two kinds of efficiency values was between 0.5 and 0.8. Most of the scale efficiency values distributed between 0.8 and 1.0, and the majority of hospitals were in a state of decreasing returns to scale. The total factor productivity of hospitals had been increasing at an average rate of 5.78% per year due to the double progress of technical efficiency and technology at annual rates of 3.77% and 1.94% respectively, further decomposing technological efficiency change, and the pure technical efficiency change increased at the speed of 3.21% per year, and the annual average rate of progress in scale efficiency was only 0.53%. The comprehensive technical efficiency was positively correlated with the turnover rate of beds, annual visits per doctor, the ratio of doctors to nurses, and negatively correlated with the number of beds, the ratio of outpatients to inpatients, the proportion of medical technical personnel, and the proportion of drugs.
CONCLUSION
Future health policies should strictly control the scale of tertiary public hospitals, pay attention to the innovation and application of hospital technology, change the hospital internal management level and management model, promote refined management, and achieve sustainable development.

BACKGROUNDWarfarin is the most common oral anticoagulant to decrease the stroke risk associated with atrial fibrillation (AF). There are very few prospective studies that have explored whether warfarin has an association with damage on renal function in Chinese patients with nonvalvular AF (NVAF). The aim of this study was to evaluate the effects of warfarin on renal function and study the factors associated with kidney dysfunction in Chinese adult NVAF patients without dialysis therapy.
METHODSFrom January 2011 to December 2013, a total of 951 NVAF patients from 18 hospitals were enrolled. The estimated glomerular filtration rate (eGFR) was calculated from baseline and follow-up serum creatinine levels. Kaplan-Meier survival curves compared the survival of a ≥25% decline in eGFR (hereafter, endpoint), while Cox models estimated hazard ratios (HR s) and 95% confidence intervals for this event after adjustment for age, gender, and selected potential risk factors for renal dysfunction. Cox regression analysis of the various clinical potential variables was performed to identify the predictors of a ≥25% decline in eGFR.
RESULTSAfter a 58-month follow-up, 951 NVAF patients were divided by observation into warfarin (n = 655) and no anticoagulation groups (n = 296) and 120 (12.6%) patients experienced renal endpoint. Kaplan-Meier survival curves showed that the survival period was not different in the two groups (χ2 = 0.178, log-rank P= 0.67), but patients with systolic blood pressure (SBP) <140 mmHg have significant difference with patients with SBP ≥140 mmHg (χ2 = 4.903, log-rank P= 0.03). Multivariate Cox regression analysis revealed baseline eGFR and SBP as independent predictors of the endpoint, with HR s of 1.00, and 1.02, respectively.
CONCLUSIONIn patients with NVAF, eGFR and SBP are associated with the deterioration of kidney function while Warfarin is not the risk factor of the ≥25% decline in eGFR.
