Objective To investigate the clinical phenotype, genotype and ultrastructural features in a pedigree with autosomal recessive congenital ichthyosis. Methods Patients were examined for clinical manifestation. PCR was carried out to amplify all the 15 exons and adjacent splice sites of TGM1 gene followed by bidirectional sequencing. Skin samples were taken by biopsy from the back of the proband, fixed in 3% glu-taraldehyde for transmission electron microscopy. Results The proband presented an intermediate clinical phenotype between lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), while his brother manifested as a collodion baby. A C551T heterozygous mutation which located in the third exon of TGM1 gene and resulted in a substitution of arginine by cysteine at codon 143 (R143C), was detected in the proband, his brother and father. Meanwhile, another heterozygous C-to-T transition at position 759 causing a substitution of serine by phenylalanine at codon 212 (S212F), was noted in the proband, his brother and mother. Electron microscopy revealed not only features of ichthyosis congenital type Ⅲ but also those of ichthyosis congenital type Ⅱ in lesions of the proband. Conclusions The patients in this pedigree carry compound heterozygous mutations, i.e. R143C, a hot missense mutation, as well as a de novo mutation S212F. The proband, who harbors mutations in the TGM1 gene, shows electron microscopic features characteristic not only of ichthyosis congenital type Ⅱ but also of ichthyosis congenital type Ⅲ.

OBJECTIVETo observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs.

METHODSOne hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation.

RESULTSThe incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05).

CONCLUSIONThe general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

BackgroundEndostatin (ES) is currently the strongest endogenous angiognesis inhibitor,and it can inhibit the occurrence of neovascularization.Various studies demonstrated that the poly RGD sequence can enhance the function of the ES gene.ObjectiveThis study was to evaluate the use of gene therapy of modified ES for alkaline burn-induced corneal neovascularization (CNV).MethodsOne hundred and two clean SD rats were randomly divided into the normal control group,the pCI empty vector group,the pCI-ES group,and the pCI-RGDRGDES group.Corneal neovascularization models were established by placing a piece of 3 mm filter paper with 1 mol/L NaOH at the central cornea for 40 seconds.3 μg of the pCI blank vector,ES-tranfected pCI blank vector,or RGDRGD-ES-transfected pCI vector was injected into the superior bulbar conjunctiva after the alkali burn twice at 1-week intervals.Area of CNV and edema of the cornea in the various groups of rats were examined daily under the slit lamp biomicroscope.1,4,7 and 14 days after operation,the rats were sacrificed by the excessive anesthesia method and corneal tissues were obtained to evaluate pathological changes.The expression of CD34 in vascular endothelial cells was detected by immunochemistry to calculate the corneal neovascular density.The expressions of VEGF mRNA and Flk-1 protein in the corneas were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blot analysis.The use and maintenance of animals followed the Statement of ARVO.Results Seven to fourteen days after corneal alkali-burning,the corneal neovascular area was smaller in the pCI-ES group and pCI-RGDRGD-ES group compared with the normal control group and pCI blank vector group (P＜0.05,P＜0.01 ),and nevascular area in the pCI-RGDRGD-ES group was smaller than that in the pCI-ES group (P＜0.05).The expression level of CD34 was significantly lower in the pCI-ES group and pCI-RGDRGD-ES group than that in the normal control group and pCI blank vector group (P＜0.05,P＜0.01 ),and the expression level of CD34 was further declined in the pCI-RGDRGD-ES group compared with the pCI-ES group (P＜0.05 ).Compared with the normal control group and pCI vector group,the expressions of the Flk-1 protein and VEGF mRNA were decreased in the pCI-ES group and pCI-RGDRGD-ES group on the fourth day after corneal alkali-burning (P＜0.01,P＜0.05 ),and those in the pCI-RGDRGD-ES group were less than the pCI-ES group (P＜ 0.05,P＜ 0.05 ).Conclusions Subconjunctival injection of both ES and modified RGDRGD-ES genes result in significant suppression of CNV in vivo,and modified RGDRGD-ES appears to be more effective than native ES.The main mechanism of ES in inhibiting neovascularization is to downregulate the expression of VEGF and Flk-1.

Objective To explore a method for isolation and culture of human epidermal stem cells. Methods Epidermis was obtained by digesting human foreskin with Dispase Ⅱ and Trypsin-EDTA.After suspension on the epidermal stem cell medium (ESCM), these single epidermis cells were inoculated onto human collagen Ⅳ-coated flasks and cultured at 37 ℃ in a humidified atmosphere containing 5% CO_2 for 10 min. The nonadherent cells were rinsed off 10 min after inoculation, and the adherent cells continued to be cultured after enriching and abstraction by type Ⅳ collagen. The cell growth was observed through inverted microscope, and the cell cloning efficiency and time of clone sustain were also detected. Immunocytochemistry was used to observe the expression of ?_1-integrin and keratin 19(K19). Keratinocytes were served as controls. Results It was revealed by histological observation that colonies were formed 24 hours after inoculation. The isolated and cultured cell cloning efficiency was higher and the time of clone sustain was longer than that of the control group. Positive expression of ?_1-integrin and K19 of cultured cells was detected by immunocytochemistry. Conclusion Adult epidermal stem cells could be successfully isolated and cultured by adhension with type Ⅳ collagen and culture with ESCM.
