Background There have been an abundance of literature on the analysis of the mechanical characteristic of the sclera at the entire seleral level in high myopia.However,some recent studies on high myopia are focused on the mechanical changes of the sclera on a cellular level. Objective This experiment was purposed to study how transforming growth factor-β2(TGF-β2)affected sclerotic desmocytes and the mechanical behaviors of scleral fibroblasts in the posterior part of the eyes in guinea pigs with experimental myopia. Methods Induced myopic animal models were established by wearing-10.00 D concave lens for 30 days in lateral eyes of 2-week-old guinea pigs.The fellow eyes were used as control group.Another 5 matched animals served as normal controls.The scleral fibroblasts of each group were purified with the tissue explant method and passaged for 2 generations in vitro.Cultured cells were identified by immunochemistry with vimentin,desmin,keratin and S-100 antibodies.Different concentrations of TGF-β2(0,1,10,100mg/L)were added into serum-free DMEM for 24 hours,and the viscoelastic properties of scleral fibroblasts were measured by micropipette aspiration technique. Results Compared with the fellow,eyes and normal control eyes,the equilibrium modulus and apparent viscosity in model eyes were significantly higher(P＜0.05).After treatment of TGF-β2,the equilibrium modulus and apparent viscosity in the model group and fellow eyes were positively correlated with the concentrations of TGF-β2(r=0.743,r=0.533,r=0.654,r=0.576,P＜0.05).Following the addition of 1 mg/L TGF-β2 and 10 mg/L TGF-β2,the equilibrium modulus and apparent viscosity of scleral fibroblasts were significantly reduced in model eyes compared with fellow eyes(P＜0.05).No significant difference was found in the equilibrium modulus and apparent viscosity of scleral fibroblasts between model eyes and fellow eyes after treatment with 100 mg/L TGF-β2(P＞0.05). Conclusion TGF-β2 car increase the mechanic indexes in a concentration.dependent manner.1 mg/L,10 mg/L TGF-β2 can lower the equilibrium modulus and apparent viscosity of scleral fibroblasts of normal eye and thus cause more changes in the mechanical behavior of scleral fibroblasts.

OBJECTIVETo analyze the indication of reoperation of thyroid cancer and to explore the timing, surgical pattern of reoperation.

METHODSProtocols of 72 patients underwent reoperation of thyroid cancer from June 2003 to August 2006 were reviewed retrospectively. Causes for reoperation were as follows: residue of the tumor locally as the inappropriate initial operation; local recurrence and cervical lymph node metastasis; before (131)I ablation which differentiated thyroid cancer with distant place metastasis. The reoperation style included residual lobectomy plus isthmus with single tumor below 2 cm, total thyroidectomy in most the other conditions and selective lymph node dissection in finding or suspected cervical lymph node metastasis.

RESULTSThe rate of residual in thyroid confirmed by postoperative pathology was 47.1% (32/68). The rate of residual in cervical lymph node was 81.4% (35/43). The rates of temporary and permanent laryngeal recurrent nerve injury were 5.6% (4/72) and 1.4% (1/72) respectively. The rates of temporary and permanent hypocalcemia were 26.4% (19/72) and 1.4% (1/72) respectively.

CONCLUSIONSInadequate operation, local recurrence and cervical lymph node metastasis of thyroid cancer need revision surgery undoubtedly. The optimal treatment was total thyroidectomy and level VI, VII central compartment lymph node dissection plus intraoperative frozen-section evaluation.

ObjectiveTo evaluate the neurobiological characteristics of human histio-amniotic mesenchymal (hAMCs) and effect of hAMCs transplantation into the brain to treat Parkinson's disease(PD) modle mice.MethodsThe expressions of mesenchymal stem cells, neural stem cells, dopaminergic neurons and markers related to neurogenesis such as Vimentin, STRO-1, nestin, CD133, β-tubulin, TH, DAT, Ngn2 and mash-1 in hAMCs were evaluated through immunocytochemical stain; and the mRNA transcriptions of neural stem cell markers, Vimentin and nestin in hAMCs were detected by RT-PCR. The PD model was induced by MPTP(i.p.) in C57BL/6 mice transplanted with hAMCs into the right striatum. The therapeutical effect of hAMCs on PD mice was evaluated by spontaneous movement, rotating bar test and the immunohistochemistry of anti-human chondrosome and TH antibodies in striatum.ResultshAMCs induced by nerve cells culture medium, expressed mesenchymal stem cells, neural stem cells, dopaminergic neurons and other specific markers related to neurogenesis mentioned above. The frequency of spontaneous movement in PD mice was significantly increased(P<0-05), and the time of rotating bar was obviously prolonged(P<0-05) after transplantation with hAMCs.ConclusionhAMCs possess the characteristics of nerve cells after cultured in vitro and can significantly recover the damage of motor function induced by MPTP after transplantation into striatum in PD model mice.

To follow up until half a year after discharge and record growth indexes of premature.Results The growths of body weight, body length and head circumference of touch group in 42 days,4 months, 6 months were larger than those of control group ( P ＜ 0. 05 ). Conclusions Touch care can promote premature growth.

OBJECTIVETo investigate the distribution of γ-glutamyl hydrolase gene (GGH) 452C/T genotype and allele frequency in children with acute leukemia (AL) and healthy children.

METHODSBone marrow samples from 92 children with AL and peripheral blood samples from 124 healthy children were obtained to prepare complementary DNAs (cDNAs). The cDNAs were analyzed for a GGH 452C/T polymorphism by reverse transcriptase-polymerase chain reaction-denaturing gradient gel electrophoresis (RT-PCR-DGGE) and direct sequencing.

RESULTSThe frequencies of the AL patients with TT, CT and CC genotypes were 2.2%, 13.0% and 84.8%, and the frequencies of the control children were 1.6%, 16.9% and 81.5%, respectively. There was no significant difference in GGH genotype or T allele frequency between the two groups (P> 0.05). However, the T allele frequency in Han Chinese children was significantly different from those reported in Japanese, Mexican and African-American populations.

CONCLUSIONThe frequency of 452C/T polymorphism of GGH gene in Han Chinese children has been determined. The results suggested that an ethnic difference may exist.
