Journal of Applied Clinical Pediatrics 2004;0(09):-
Systemic lupus erythematosus(SLE) is an autoimmune connective-tissue disorder with a wide range of clinical features.Although the clinical symptoms and immunological findings of pediatric SLE are similar to those of adult SLE patients,the pediatric SLE has some special aspects.In the recent years,although there was no abrupt development in the diagnosis and treatment of SLE,there were some new findings,maybe not mature.On the basis of recent findings outsides,this study drew attention to the advances in the novel clinical manifestation,update treatment of pediatric SLE.

ObjectiveTo observe the discoloration of chemical indicator cards in different positions in pressure steam sterilization bags and stetilization effect.MethodsFrom January 2009 to January 2011,168 packages needing sterilization were divided into group A and group B randomiy with 84 packages in each.We put chemical indicator cards on different positions in the packages.Then discoloration of chemical indicator cards and the qualified rate of bacteriology detection were observed.ResultsThere were 9cases of uneven discoloration in group A,and the incidence rate was 10.71%,higher than group B.The unqualified rate of bacteriology detection in group A was 2.38%,higher than group B(1.19%),but the difference was not statistically significant.ConclusionsChemical indicator cards could reflect the effect of sterilization,but placing them in different positions can appear different results.The chemical indicator cards that placed between the two packing layer could provide powerful evidence for sterilization effects for clinicians,and avoid unnecessary economic waste in Sterilization and Supply Center,which is worthy of being widely used in Sterilization and Supply Center.

AIM: To study the visual quality, dry eye and biomechanical stability of patients with myopia and astigmatism after different corneal refractive surgeries. ·METHODS: A total of 986 patients with myopia and astigmatism were selected as the research object in our hospital from July 2015 to July 2016, according to the operation mode of the selection of the research object, the 986 patients were randomly divided into small incision lenticule extraction ( SMILE) group, femtosecond laser in situ keratomileusis ( FS-LASIK ) group, sub-bowman-keratomileusis ( SBK ) group and laser-assisted in situ keratomileusis ( LASIK ) group. The postoperative visual quality was determined by comparing the diopter, uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) and high-order image difference of 25d, 90d. The postoperative dry eye condition was determined by comparing the postoperative tear secretion test ( Schirmer Ⅰ test ) , tear film rupture time ( BUT ) and fluorescence staining ( FS) . The biomechanical stability of the patients was determined by comparing the corneal hysteresis ( CH ) and corneal resistance factor ( CRF ) values of the four groups. ·RESULTS: The diopter, UCVA, BCVA and high-order aberration comparison of FS-LASIK group, SBK group and LASIK group between before and after surgery, showed no significant difference ( P>0. 05 ); on diopter, BCVA, UCVA, there was no significant difference between before and after surgery in SMILE group (P>0. 05), but statistical significance difference on high order aberration (P<0. 05). The BUT and FS value of the four groups decreased obviously after operation, and the difference was statistically significant (P<0. 05). In LASIK group SIt after operation significantly decreased, with statistically significant compared with that before operation ( P <0. 05). After operation, CH and CRF of the four groups decreased with significant differences (P<0. 05). ·CONCLUSION: SMILE, FS-LASIK, SBK and LASIK are equally safe, effective and stable in the treatment of myopia and astigmatism.

Objective To evaluate the sensitivity and specificity of a rapid one-step test for the detection of Helicobacter pylori antigen in stool samples. Methods 13C-urea breath test (13C-UBT) and rapid urease being taken as “gold standard”, Helicobacter pylori stool antigen (HpSA) was detected with Atlas rapid one-step test among patients with syndromes in upper alimentary tract. These patients were divided into two groups. One was pretreatment group that included 62 cases and the other one was post-treatment group with 42 cases. Results In pretreat_ment group, there were 24 Hp positive cases and 38 negative ones according to the golden standard, 27 positive and 35 negative according to one-step HpSA assay, and the sensitivity and specificity was 100% and 92% respectively; In post-treatment group, 15 positive and 27 negative according to the golden standard, 19 positive and 23 negative according to one-step HpSA assay, and the sensitivity and specificity 93%and 81% respectively; the total sensitivity and specificity was 97% and 88% respectively. Conclusions HpSA rapid one-step test has good sensitivity and specificity in diagnosis of Hp infection and judgment of Hp eradication.

Chinese Journal of Applied Physiology 2015;31(2):166-169
OBJECTIVETo Study the effect of anti-aging and its mechanism of total saponins of Wu-He Dipsacus asper on skin of mice-aging model.
METHODSForty-eight mice were randomly divided into blank control group, model group, low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group and positive control group( n = 8) . The mouse model of skin aging was established by nape subcutaneous injection of 5% D-galactose (0.025 mL/(g · d)), the mouse of low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group were administered with total saponins of Wu-He Dipsacus asper (50 ml/(kg · d), 100 mL/(kg · d), 200 mL/(kg · d)), the mice of the positive control group were administered with vitamin E(50 mg/(kg · d)) for 42 d. The content of hydroxyproline (HYP) and lipofuscin (LF) were measured in skin of each group mice, the activity of catalase (CAT) glutathione peroxidase ( GSH-Px) superoxide dismutase (SOD) and the content of malondi- aldehyde (MDA) were determined in serum and skin of each group mice.
RESULTSCompared with blank control group, the content of HYP decreased significantly and the content of LF increased significantly in skin, the activities of CAT, GSH-Px and SOD decreased significantly and the content of MDA increased significantly in serum and skin of model group; Compared with model group, the content of HYP increased significantly and the content of LF decreased significantly in skin, the activities of CAT, GSH-Px and SOD enhanced significantly and the con- tent of MDA decreased significantly in serum and skin of low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group and positive control group; Compared with low-Dipsacus group, the content of HYP increased significantly and the content of LF decreased significantly in skin, the activities of CAT, GSH-Px and SOD enhanced significantly and the content of MDA decreased significantly in serum and skin of high-Dipsacus group and positive control group; The activity of SOD in serum and skin had a significant positive correlation with the content of HYP, and a significant negative correlation with LF in skin.
CONCLUSIONTotal saponins of Wu-He Dipsacus asper have obvious effect of anti-agng on skin of mouse-aging model , its mechanism is closely related to oxidative damage.
