ABSTRACT
Objective:To improve the loading technology of precision micro instruments, so as to ensure not only the quality of cleaning and sterilization, but also the safe use of instruments.Methods:From January to March, 2021, 80 sets of precision micro instruments from Sterilization Supply Center, Shanghai Jiao Tong University School of Medicine Affiliated Ruijin Hospital were randomly divided into silica gel pad loading group (group A) and silica gel stent loading group (group B), 40 sets in each group. The cleaning effect, drying effect, loading effectiveness and sterilization wet bag of the instruments in the two groups were compared, and the staff of the disinfection supply center were satisfied with the operation of the loading technology of the instruments in the two groups.Results:The qualified cleaning numbers of the instruments in group A and B were 37 and 39 respectively, and there was no significant difference between the two groups ( χ2 = 1.05, P>0.05). The qualified drying numbers in the group A and B were 29 and 38 respectively, the difference between the two groups was significant ( χ2 = 7.44, P<0.05). The effective number of loading in the group A and B were 30 cases and 39 cases respectively, the difference was significant between the two groups ( χ2 = 8.54, P<0.05). The number of sterilized wet bags in the group A and B were 6 cases and 0 cases respectively, the difference was significant between the two groups ( χ2 = 6.49, P<0.05). The satisfaction of 44 personnel in the disinfection supply center with the operation of loading technology were 36 and 43 respectively, the difference was statistically significant between the two groups ( χ2 = 6.07, P<0.05). Conclusion:Loading precision micro instruments with silica gel stent can not only ensure the cleaning and sterilization quality of instruments, but also make the loading of instruments more safe and stable, greatly improve the working efficiency of instrument treatment and accelerate the turnover efficiency of instruments.
ABSTRACT
Objective To improve the cleaning and loading technology of nasal endoscope in order to ensure the cleaning effect, to improve the working efficiency, and to reduce the cleaning cost. Methods A total of 480 reusable contaminated nasal endoscopes were divided into two groups according to random number table: Clean and load the nasal endoscopes (group A) with the usage of metal parts to open up the leaf; Clean and load the nasal endoscope (group B) with the usage of screw driver to open up the leaf. Each group has 240 pieces. After mechanical cleaning, observe and analyze the cleaning effect, loading effectiveness, loading capacity, loading time and CSSD operators′ degree of satisfaction. Results The number of qualified cleaning joint parts of the two groups were 218 and 231 respectively, and the number of qualified cleaning leaf of the two groups were 214 and 227 respectively, and there were significant differences between the two groups (χ2= 5.828, 4.717, P < 0.05). The number of effective cleaning and loading 211 and 240 respectively, and there were significant differences between the two groups (χ2=30.865, P < 0.01). The time it takes for loading were(2.89 ± 0.22)s/piece and (1.80 ± 0.21)s/piece respectively, and there were significant differences between the two groups. There were significant differences between the two groups (t=55.535, P<0.01). Among 62 CSSD operators, there were 51 and 59 operators in the two groups are satisfied, and there were significant differences between the two groups (χ2=10.806, P<0.05). Conclusions Using the screw driver of the nasal endoscope helps to keep the leaf open during the process of mechanical cleaning, to ensure the cleaning effect, to shorten the loading time and increase the loading capacity. Thus improving the working efficiency and reducing the cleaning cost.

ABSTRACT
Objective To realize the status in the implementation of three industry standards of central sterile sup-ply department (CSSD),and provide a scientific basis for carrying out of the standards. Methods According to three standards,investigation forms were designed by specialists,written survey on 365 hospitals in 9 provinces and field investigation on 1 5 hospitals in 3 provinces were performed,the implementation of three standards were investi-gated.Results Of 365 hospitals,the number of provincial and ministerial level,municipal level,and county level hospitals were 90,87 and 188 respectively. More than 94% of hospitals established CSSD management system and regulations,>90% of hospitals met the requirements of CSSD layout;All hospitals were equipped with pressure steam sterilizer,all levels of hospitals basically equipped with the necessary equipments and facilities;CSSD respon-sible officers of 94.52% (345/365)of hospitals participated in training on standards;69.61% (252/362)of hospi-tals were using or developing CSSD information systems;>92% of the CSSD responsible officers considered that three standards played an important role in facilitating centralized management,and improving the quality of clean-ing,disinfection and sterilization.Conclusion Hospitals need to strengthen the management and training on stand-ards of CSSD,management of loaner instruments and development of information system need to be standardized.
ABSTRACT
ObjectiveTo detect the serum level of follistatin-like protein 1 (FSTL1) in patients with systemic lupus erythematosus (SLE) and its expression in renal biopsy tissues in lupus nephritis (LN) patients as well as its clinical significance were analyzed.MethodsThe serum concentration of FSTL1 in 54 SLE patients and 27 healthy controls was measured with enzyme-linked immunosorbent assay (ELISA).The distribution of FSTL1 in renal biopsy tissues was stained by immune-histochemical method.Mann-Whitney U test,t test,X2test and Pearson test were selected to compare the changes and data analysis.ResultsThe serum FSTLI level was significantly higher in SLE patients(26±21) μg/L than those of healthy controls ( 12± 14) μg/L (P＜0.01).The level of serum FSTL1 was significantly higher in SLE patients with hypertension than in patients without hypertension.The serum FSTL1 level had statistically significant changes between SLE patients with disease duration ≥ 5 years and ＜5 years.The level of serum FSTL1 correlated positively with SLEDAI score (r=0.319,P=0.022),age (r=0.700,P＜0.01),disease duration (r=0.513,P＜0.01),complement C4 level (r=0.443,P=0.004),and total serum cholesterol level (r=0.460,P=0.001 ).FSTL1 correlated inversely with platelet count (r=-0.422,P =0.001 ),anti-dsDNA antibody levels (r=-0.276,P=0.046).FSTL1 expression was evident in the cytoplasm of epithelial cells of kidney tubules.ConclusionThe level of serum FSTL1 is significantly increased in SLE patients.FSTL1 concentration correlats positively with disease activity.These data indicate that FSTL1 may play a role in the pathogenesis of SLE.
ABSTRACT
OBJECTIVE To control the quality of cleaning and sterilization of rent instruments and to secure medical safety of patients undergoing operations.METHODS We randomly chose 60 pieces of rent instruments and divided them into two groups,machinery wash group and hand wash group.Occult blood test was performed before and after washing and rinsing.RESULTS Positive rate of occult blood tests was 86.67% before either machinery or hand wash.While after machinery wash and hand wash it was 0% and 6.67%,respectively.Both wash methods had significant effect on depleting occult blood(P0.05).CONCLUSIONS Hospitals must enhance the management of rent instruments cleaning which is of poor quality at present by regulating the procedure and monitoring methods so as to ensure the quality of rent instruments cleaning and secure patients safety.
