Objective To assess the effects of surgical treatment for patients with blepharochalasis and its associated abnormali- ties. Design Retrospective case series, Participants 35 cases (52 eyes) with blepharochalasis in stable phase. Methods The correction of the abnormalities in upper eyelids: after designing the lid crease incision, the redundant eyelid skin and prolapsed fat were excised, and prolapsed lacrimal glands were sutured back into position in 18 cases (36 eyes) and ptosis was treated in 10 cases (16 eyes). The correction of abnormalities in lower eyelids: lower eyelid retraction was corrected in 4 cases (6 eyes). The correction of lateral canthus malformation: lateral canthus rounding was treated in 7 cases (14 eyes), accompanied with or followed by correction of baggy eyelid or ptosis. Main Outcome Measures The shape, location and movement of bilateral eyelids, the location of lacrimal glands and the cir- cumstance of tear secretion. Results During the follow-up of 6～60 months, the appearance and location of bilateral eyelids and can- thuses were satisfying, the function of eyelids were normal, and no dry eye symptoms were found. Two cases (3 eyes) appeared recurrent lacrimal gland prolapse 29 and 36 months postoperation and received surgeries for correction again. There was no recurrence after the second prolapse correction surgery in the follow-up of 18 and 24 months respectively. Conclusions Surgical treatment for patients with blepharochalasis and its associated abnormalities is safe and effective. Its recurrence rate is low.

OBJECTIVETo study the inhibitory effect of Juhua Jueming powder (JJP) on high-risk corneal transplantation immune rejection in rats.

METHODSThe high-risk corneal transplantation immune rejection rat model was established by inducing corneal neoangiogenesis by suture method and the penetrating transplantation. Model rats were divided into two groups, the treated group and the control group, they were administered with JJP 0.1 g (dissolved in 2 mL water) and normal saline respectively via gastric infusion every day after transplantation. The survival status of the allograft, histopathology, local and systemic immune status in the recipients were observed using immunofluorescence histochemistry and flow cytometry.

RESULTSThe survival time of the allograft in the treated group (14.50 +/- 3.55 days) was significantly longer than that in the control group (8.25 +/- 0.71 days, P < 0.01). Levels of Fas, FasL expressions in iris were stronger, and the percentage of CD4 CD FOXP3 positive cells in peripheral blood was less (5.11 +/- 3. 92% vs. 14.81 +/- 2.58%) in the control group than those in the treated group respectively. The concentration of IL-2 was lower while that of IL-10 was higher in aqueous humor of the treated group than those of the control group, respectively.

CONCLUSIONJJP has certain effect for preventing high-risk corneal transplantation immune rejection in rat model.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.

Objective To study the changes of antigen-specific T helper type 1 (Th1) cells and Th2 cells in patients with pemphigus vulgaris (PV) at different stages,so as to better understand the roles of autoreactive T cells in PV.Methods The DG3 (96-112) peptide was synthesized.Twenty-four patients with PV and 10 health checkup examinees were included in this study.Peripheral blood mononuclear cells (PBMCs) were obtained from the health checkup examinees and all the patients before treatment and seven patients about one month after treatment,and stimulated with the DG3 peptide of 10 mg/L for different durations.Then,enzyme-linked immunospot (ELISPOT) assay was performed to count the number of DG3-specific IFN-γ+ Th1 cells,IL-4+ Th2 cells and memory B cells.One-way analysis of variance (ANOVA) and t test were done to compare the number of cells between different groups,and Pearson correlation coefficient was used to evaluate the correlation among Th cells,memory B cells and anti-desmoglein 3 (Dsg3) antibody titers.Results In these patients,the male to female ratio was 1.67 ∶ 1,and the average age was (56.59 ± 14.66) years.Compared with the health check-up examinees,the patients with PV showed a higher absolute number of DG3-specific IFN-γ+ Th1 cells (420.18 ± 350.29 vs.145.12 ± 86.56,t =3.25,P ＜ 0.05),but a similar absolute number of specific IL-4+ Th2 cells (366.76 ± 192.44 vs.335.88 ± 164.96,P＞ 0.05) per 5 × 105 PBMCs.The percentage of DG3-specific IL-4+ Th2 cells in Th2 cells was 37.03％ ± 23.44％,and the percentage of IFN-γ+ Th1 cells was 23.62％ ± 16.77％ in peripheral blood of patients with PV.The number of DG3-specific IL-4+ Th2 cells per 5 × 105 PBMCs significantly decreased from 452.82 ± 199.29 before treatment to 241.68 ± 160.60 after treatment in seven patients (t =2.48,P ＜ 0.05).There was no significant correlation between specific Th cells,memory B cells and anti-Dsg3 antibody titers (all P ＞ 0.05).Conclusions The peptide DG3 (96-112) has pathogenic epitopes which could be recognized by specific Th cells of patients with PV.Both antigen-specific IFN-γ+ Th1 cells and IL-4+ Th2 cells play certain roles in the pathogenesis of pemphigns vulgaris,and IL-4+ Th2 cells appear to be more important.

Objective To estimate the impact of universal salt iodization on child intelligence quotient (IQ) development in Hainan province. Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.
