ABSTRACT
Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.
ABSTRACT
Objective@#To investigate the relationship between the recurrence of benign paroxysmal positional vertigo(BPPV) and the levels of bone mineral density(BMD) and estrogen in postmenopausal women.@*Methods@#A total of 38 postmenopausal women with recurrent BPPV were recruited as study group, in the First Affiliated Hospital of Soochow University from December 2013 to June 2017. Meanwhile, 49 normal menopausal women were included as control. All patients were natural menopausal for over one year.The patients were diagnosed as BPPV based on results of Dix-Hallpike test and Roll-test, with at least two episodes of recurrent onset. In the subjects, BMD was measured by dual X-ray absorptiometry of lumbar vertebrae. Estrogen levels were obtained by testing serum estradiol (E2) levels in early morning fasting venous blood. In the present study, we compared the level of E2 and the value of BMD in two groups by SPSS 21.0. In the study group, patients with decreased BMD were divided into two groups: treatment and untreated group. The recurrence rate of BPPV was compared between the two groups within 12 months.@*Results@#①The averagel levels of E2 and BMD in the study group were (16.21±11.00)ng/L and -1.68±0.98) respectively, which were significantly lower than those in the control group (t value was 7.03 and 8.05 respectively, both P<0.05). The averagel levels of E2 and BMD incontrol group were(28.52±6.34)ng/L and -0.18±0.77 respectively. ②The number of patients with decreased BMD in the study group (30 cases) was more than that in control group (6 cases), and the difference was statistically significant (P<0.05). ③ The recurrence rate of BPPV in treatment group [17.6%(3/17)] was significantly lower than that of untreated group [61.5%(8/13)], and the difference was statistically significant (P<0.05).@*Conclusion@#Recurrent BPPV in postmenopausal women usually accompany with low levels of estrogen and BMD. Active treatment is helpful for their recurrence of BPPV.
ABSTRACT
Objective To identify highly sensitive and specific antigens in Aeromonas hydrophila strain ATCC7966 by using immunoproteomics.Methods Outer membrane proteins were extracted from the Aeromonas hydrophila strain by using two-dimension electrophoresis and identified by LC-LTQ-XL-MS ( liq-uid chromatography coupled with linear ion trap mass spectrometry).Western blot assay was performed to screen out the immunogenic proteins.Results A total of 43 peptides representing 39 proteins were identi-fied by LC-LTQ-XL-MS.Among the 39 proteins, 69% were outer membrane proteins and 12% were inner membrane proteins.They were involved in the process of transportation, cell motility, biosynthesis, etc. One candidate vaccine antigen was identified by using two-dimensional Western blot analysis .Conclusion The immunoproteomics approach could be used to identify immunogenic proteins of Aeromonas hydrophila. This study provided references for further investigation on candidate vaccine antigens.
ABSTRACT
The statistical data on Traditional Chinese Medicine (TCM) has not been fully exploited,resulting in the gap between the storage and usage of the TCM statistical data resources. The study on the retrospective collection, arrangement and application of Traditional Chinese Medicine Statistical Data aims to enhance the usage of TCM statistical data, basing on the collection and arrangement of the authoritative TCM statistical data, common analysis of the TCM statistical data from the founding of the People Republic of China.A pilot TCM Statistics Information Database and a TCM Health Statistics Data Query System have been established with the computer database technology, the object-oriented programming tool (C#) and the Internet Browser-based presentation programming tool (ASP. Net), providing the initial functions of the data retrieval and the graphical presentation of the search results on TCM statistics data. This paper explores "statistical data-oriented with attributes description" as the idea to establish the statistical database of complex statistical data, with the solution of the data problems such as numerous of data, diverse of data units, lack of regularity and hard to be classified. The study realizes the building of TCM Statistics Information Database and the retrieval finction of TCM statistical data, which lays a foundation on the building of Traditional Chinese Medicine Industry Statistics Database and the information services of TCM statistics data in the future.
ABSTRACT
Basing on the introductions to the three levels about the health statistics,including the concept of staffstics,the overview of the health statistics development and the current status of the Health Statistics on Traditional Chinese Medicine,we discuss the significance of Health Statistics on Traditional Chinese Medicine and analysis its existing problems,possible reasons and solutions.
