Objective To explore the clinical significance of detection of IL-17 and peripheral blood eosinophil(EOS) count in whee-zing children under 5 years old.Methods Fifty-three children with recurrent wheezing under 5 years old had been randomly enrolled including 43 boys and 10 girls.They were divided into 2 groups :wheezing group Ⅰ,in which,the patients with atopic high risks(n=27);whee-zing group Ⅱ,in which,the patients without atopic high risks(n=26).Children without infectious diseases such as hernia and renal calculus had been enrolled randomly as control group(n=20),including 11 boys and 9 girls.After taking 3 mL venous blood and centrifuging of patients in 3 groups,the level of IL-17 in the serum was measured by double-antibody sandwich enzyme-linked immunosorbent assay,peripheral blood EOS count was performed in the meantime by means of eosine staining.Results The serum levels of IL-17 in wheezing groups [(1 469.315?978.300) ng?L-1,(263.340?131.800) ng?L-1]were significantly higher than that of control group[(36.478?2.000) ng?L-1](Pa0.05);serum IL-17 and peripheral blood EOS count had positive correlation(r=0.933,P

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

Background Researches demonstrated that dendritic cells(DCs) are uniformly immature in the central cornea but mature in the peripheral region of cornea.So an important question is which factor impact the maturation of DCs,especially in terms of corneal transplant rejection and the known roles of DCs in the development and persistence of some corneal diseases.Objective This study aimed to examine whether corneal stroma cells (CSCs) inhibit DCs maturation through secreting transforming growth factor beta 2 (TGF-β2) and prostaglandin E2 (PGE2).Methods DCs,T cells and CSCs were isolated and cultured from clean BALB/c and C57BL/6 mice.The level of PGE2 and TGF-β2in CSCs culture supernatant and the fresh RPMI 1640 medium were then analyzed by enzyme linked immunosorbent assay (ELISA).During the DCs maturation stage,the neutralizing TGF-β2 antibody and the EP2 receptor antagonist AH6809 were added in the CSCs culture supernatant respectively.According to the different treatment,cultured cells were assigned to different groups as follows:control group,CSCs culture supernatant group,AH6809 group,TGF-β2 antibody group,AH6809 +TGF-β2 antibody group.Subsequently,the cellular surface markers for DCs,including CD11c,CD80,CD86,and MHC- Ⅱ,were analyzed by flow cytometry.The capability of stimulating the proliferation of T lymphocytes was evaluated by allogeneic mixed lymphocyte reactions,and the function of endocytosis was assessed by fluorescein isothiocyanate-dextran(FITC) uptake.Results The data of ELISA showed a higher concentration of TGF-β2 and PGE2 in murine CSCs culture supernatant than in the fresh RPMI 1640 medium.Compared with the CSCs culture supernatant group,the expression of CD80,CD86,and MHC- Ⅱ was up-regulated ( P ＜ 0.05 ),the expression of dextran was down-regulated ( P ＜ 0.05 ),and the stimulate index was increased( P＜ 0.05 ) in the TGF-β2 antibody group; the expression of CD86,and MHC-Ⅱ was up-regulated (P＜0.05),the expression of dextran was down-regulated ( F =13.740,P =0.006 ),and the stimulate index was increased(P＜0.05) in the AH6809 group;the expression of MHC-Ⅱ was up-regulated and the stimulate index was increased with statistical difference in interaction(P＜0.05 ) in the AH6809+TGF-β2 antibody group.Compared with the control group,the expression of CD80 and CD86,and the stimulate index was still lower(P＜0.05 ).Conclusions TGF-β2 and PGE2 contribute to the inhibitory effects on DCs maturation mediated by murine CSCs in vitro and further have additive effect on the immunosuppression of DCs.

AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.

AlM:To evaluate the clinical efficacy of intravitreal injection of ranibizumab combined with macular grid photocoagulation for diabetic macular edema ( DME) .METHODS:Totally 60 eyes ( 60 patients ) with DME were randomly divided into 2 groups: 30 eyes of simple injection group underwent intravitreal injection of ranibizumab, and 30 eyes of combined treatment group underwent intravitreal injection of ranibizumab and macular grid photocoagulation 1wk later. The best corrected visual acuity ( BCVA ) , central macular thickness ( CMT ) measured by optical coherence tomography ( OCT ) and postoperative complications were observed.
RESULTS:ln simple injection group, the BCVA after operation were separately 0. 390 ± 0. 075 (4wk), 0. 367 ± 0. 088 (8wk) and 0. 319 ± 0. 064 (12wk), the CMT after operation were separately 221. 63 ± 112. 34μm (4wk), 337. 73±99. 56μm (8wk) and 432. 92 ± 100. 46μm (12wk), which were much better than pre-operation. But during follow-up, the BCVA presented down trend and the CMT was on the rise slowly. ln combined treatment group, the BCVA after operation were separately 0. 385 ± 0. 036 (4wk), 0.382±0.079 (8wk) and 0.377±0.097 (12wk),the CMT after operation were separately 249. 77 ± 106. 55μm (4wk), 270. 40 ± 92. 88μm (8wk) and 275. 84 ± 97. 34μm (12wk ), which were satisfactory and steady during follow-up, better than simple injection group (P<0. 05).CONCLUSlON:lntravitreal injection of ranibizumab can effectively improve visual acuity and decrease central foveal thickness for patients with DME, combining with macular grid photocoagulation can ensure therapeutic effects steady and permanent.

Objective: To learn the health literacy level and its influencing factors among junior high school students in Jiaxing, so as to provide basis for health promotion of adolescents. Methods: The junior high school students who had been studying and living in Jiaxing for more than six months were selected by multistage cluster random sampling method. A questionnaire survey was conducted to collect general information and health literacy level (including basic knowledge and concept, healthy lifestyle and behaviors, and basic skills) of these selected students. The multivariate logistic regression model was used to analyze the influencing factors for health literacy. Results : Of 1 773 questionnaires collected, 1 738 were valid, accounting for 98.03%. The level of health literacy in the junior high school students in Jiaxing was 22.84% ( 95%CI: 20.87%-24.82% ), The levels of basic knowledge and concept, healthy lifestyle and behaviors, and basic skills were 55.29% ( 95%CI: 52.95%-57.63% ), 21.75% ( 95%CI: 19.81%-23.69% ), 53.05% ( 95%CI: 50.70%-55.40%), respectively. Multivariate logistic regression analysis showed that the second grade and above ( OR: 1.609-1.835, 95%CI: 1.195-2.459 ), mother's educational level of technical secondary school/senior high school and above ( OR: 1.965-1.976, 95%CI: 1.276-3.357 ), and self-rated academic achievement of medium and above ( OR: 1.881-2.441, 95%CI: 1.359-3.335 ) were the promoting factors for health literacy level of junior high school students; self rated health status as unhealthy ( OR=0.254, 95%CI: 0.089-0.721 ) was an obstructive factor. Conclusions The health literacy level of the junior high school students in Jiaxing was 22.84%. The level of healthy lifestyle and behaviors was the lowest in three aspects. Grade, mother's educational level, self-rated academic performance and self-rated health status may have impacts on health literacy level of junior high school students.

To evaluate the visual performance of the patients with traumatic corneal astigmatism, after the treatment of topography guided off-flap epipolis laser in situ keratomileusi (off-flap Epi-LASlK).
●METHODS: This prospective clinical study was comprised of 21 eyes of 21 patients with irregular corneal astigmatism caused by trauma, they were treated by off-flap Epi - LASlK from July 2012 to December 2013. The data included uncorrected visual acuity ( UCVA), best spectacle - corrected visual acuity ( BSCVA ), contrast sensitivity 1, 6mo before and after surgery; the healing area percentage of corneal epithelia, the healing time of corneal epithelia and pain score at 3d after surgery.
●RESULTS: Postoperative 1mo both UCVA and BSCVA were improved significantly than that before surgery (t =15. 703, 4. 351, P< 0. 05); Compared with the 1mo after surgery, UCVA at 6mo after surgery raised significantly (t= 6. 867, P <0. 05). There was no statistical significance between 6 and 1mo after surgery about BSCVA (t= 1. 497, P = 0. 140 ). After surgery, mean spherical equivalent (SE) was reduced from -2. 43±3. 02D to -0. 23±0. 49D (P<0. 05), and the mean cylinder was reduced from -1. 86± 2. 23D to - 0. 46 ± 1. 03D (P< 0. 05). Postoperative 1mo,4 kinds of spatial frequency and contrast sensitivity had no significant difference compared with the preoperative (P>0. 05 ). Postoperative 6mo except the 3c/ d spatial frequency, the remaining 3 spatial frequency contrast sensitivity compared with those before operation were significantly improved ( P < 0. 05 ). The healing area percentage of corneal epithelia was 92. 46% ±8. 24% (80% -100%) at 3d after surgery; The healing time of corneal epithelia was 3. 50 ± 1. 56d; Pain scores at 3 and 7d after surgery was 1. 54±1. 32 and 0. 04±0. 64, respectively.
●CONCLUSlON: Topography-guided off-flap Epi-LASlK is safe and effective in treating the patients with traumatic corneal irregular astigmatism. The operation can improve both the contrast sensitivity and the visual performance.
