ABSTRACT
Objective To discuss nursing service and charge in order to establish standard and perfect nursing cost accounting system. Methods Nursing charge was described through analyzing the nursing technology during treatment of long-term hospitalization patients and no charge of disposable items. Results Nursing work was nearly a no-reward technological service, the proportion and the standard of nursing charge was low, the charge of nursing items was incomplete, labor cost was neglected and nursing value could not be really embodied. Conclusions Nursing managers should strengthen the nursing cost management in order to establish perfect and standard nursing cost accounting system.

s:To resolve the problem of the accuracy and standardization of STR PCR typing in forensic science practice,we have designed a new method to produce standard D12S375 allelic ladder.Seven different PCR amplified D12S375 allelic fragments were isolated from the gel,eluted into the distilled water and reamplified by PCR.The purified allelic fragments were then blunt end subcloned individually into the pUC plasmid vectors and transfected into competent E.coli DH5? TM cells.The sequencing results confirmed that the size and the constructure of the inserts were correct.The recombinant plasmids DNA with 7 inserts were then used as templates for reamplification to generate D12S375 standard ladder, with which the genetic polymorphisms of D12S375 locus in Chinese Han population in Chengdu,Hui population in Gansu and Wei population in Xinjiang were studied.
ABSTRACT
For the purpose of detecting the polymorphism of the human eighth complement component(C8A),an allele specific amplification method were established for detecting two alleles of C8A based on a nucleotide exchange of the C8? cDNA sequence.100 DNA blood samples from unrelated individuals of Han population in Chengdu were typed by this method.The result of comparison with the data of protein typing of the same samples using SDS PAGE method proved that the described method is efficient,correct and reliable for C8A genotypes.This methtod is valuable for further application in population genetic study and forensic science practice.
