With the reform of the medical and health system entering a critical period,public hospitals have also exposed new risks and challenges in economic operation.As an important means of hospital standardized management,internal control can better prevent and resolve the risk of hospital economic operation and ensure the sustainable operation of the hospital.By interpreting the requirements of current national policies on hospital internal control,it analyzes the functional positioning of financial and accounting supervision in hospital internal control,shares the internal control implementation path of sample hospitals from the perspective of financial and accounting supervision,and puts forward suggestions on strengthening internal control construction of public hospitals in the new era,in order to lay a good foundation for the high-quality development of hospitals.

<p><b>OBJECTIVE</b>To explore the relation between genetic polymorphisms of NQO1, GSTT1 and risks of chronic benzene poisoning (BP).</p><p><b>METHODS</b>A case-control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. Polymerase chain reaction (PCR), denaturing high-performance liquid chromatography(DHPLC) and sequencing were used to detect the single nucleotide polymorphisms(SNPs) of the promoter and complete coding-region of NQO1 gene. Multiple PCR was used to detect GSTT1 genotype.</p><p><b>RESULTS</b>In smoking population, there was 7.73-fold (95% CI: 1.71-34.97, P = 0.010) of risk in BP subjects carrying NQO1c. 609 T/T genotype, compared with those carrying C/C and C/T. genotype. In drinking population, the individuals carrying the 6th extron of NQO1c. 609 T/T homozygote genotype had a 11.00-fold(95% CI: 1.89-63.83, P = 0.005) risk of BP compared to those with NQO1c. 609 C/T and C/C genotypes.</p><p><b>CONCLUSION</b>The subjects carrying NQO1c. 609 T/T genotype and together with the habit of smoking or drinking may be more susceptible to BP.</p>
