Objective To compare the efficacy and safety of vitrectomy combined with internal limiting membrane flap and vitrectomy combined with internal limiting membrane peeling for the treatment of idiopathic macular hole with different sizes.Methods A total of 127 consective patients (127 eyes)were divided into two groups according to the size of the hole diameter of the smallest split points by less than or equal to 500 μm (small diameter macular hole group) and more than 500 μm (huge diameter macular hole group).According to different surgical methods the patients were divided into non ILM flap coverage group (peeling 1 group and peeling 2 group) and ILM flap cover group (covering 1 group and covering 2 group).All the patients underwent vitrectomy combined with internal limiting membrane peeling or vitrectomy combined with limiting membrane flap.Preoperative and postoperative best correct visual acuity,closure ratio of macular hole and postoperative major complications were observed and followed up.Results The postoperative best correct visual acuity improved in all the groups,there was no significance difference between small diameter macular hole group and huge diameter macuiar hole group (t =0.112 2,0.750 8;all P >0.05).The closure ratio of peeling 1 group and covering 2 group at postoperative 6 months were all 100%,there was no statistical difference (P > 0.05),which in peeling 2 group and covering 2 group were 84.85% and 100.00%,there was statistical difference (x2 =13.292,P < 0.05).There was no statistical difference in preoperative defect diameter of the inner and outer junction between peeling 2 group and covering 2 groups (P >0.05),there was also no statistical difference between peeling 2 group and covering 2 groups at postoperative 1 months (P > 0.05),but there were statistical differences at postoperative 3 months,6 months and 12 months (all P < 0.05),the covering 2 group were less than the peeling 2 group.Conclusion ILM flap coverage helps to heal macular holes greater than 500 μm diameter,and has no extra effect on healing of diameter less than 500 μm.

Objective To investigate the effect of intermittent high glucose on proliferation, apoptosis, and cell cycle progression of INS-1 cells, and the possible intracellular pathways activated by intermittent high glucose. Methods Cell viability was evaluated by cell counting kit, the cell cycle was determined by flow cytometry,Annexin-V/PI double-labeled cell apoptosis detection kit was used to monitor cell apoptosis. Cell cycle related protein Skp2 and p27 expressions were detected by Western blot. Results ( 1 ) Both intermittent and constant high glucose significantly inhibited the growth of INS-1 cells, and the former effect was more significant. ( 2 ) Intermittent and constant high glucose levels significantly increased apoptosis in INS-1 cells, and the former effect was more significant. (3) Intermittent and constant high glucose levels significantly inhibited the cell process, the G0/G1 cell cycle arrest also was induced by intermittent high glucose, resulting in lowered proportion of the G2/M phase and S phase of INS-1 cells. (4) Intermittent and constant high glucose significantly decreased the level of protein Skp2 and increased the level of cell cycle related protein p27. Conclusion Intermittent high glucose levels affect INS-1 cell growth and proliferation, as well as induce cell apoptosis, probably by decreasing the level of protein Skp2 and increasing the level of p27 in the cells, resulting in arrest of progression through the G1 phase to the S phase of INS1 cells, and thus impairment of cell proliferation.

OBJECTIVETo observe the changes of mental stress life events (MSLE) in patients with cyclomastopathy of liver stagnation syndrome type (LSS).
METHODSClinical epidemiological research method was adopted, the changes of MSLE were observed in cyclomastopathy patients of LSS or non-LSS, classified by syndrome differentiation of TCM.
RESULTSNot only the mean age (33.38 +/- 6.76 years) of patients with LSS was obviously lower than that of patients with non-LSS (38.36 +/- 9.89 years, P < 0.01), but also the mean age of patients with moderate and serious symptoms of LSS (33.96 +/- 7.31 and 37.43 +/- 7.38 years) were higher than that of patients with mild symptoms of LSS (31.67 +/- 5.39 years, P < 0.05 and P < 0.01). MSLE score of patients with LSS (32 scores) was significantly higher than that of patients with non-LSS (22 scores, P < 0.01). MSLE score of patients with moderate and serious LSS was 34.69 +/- 17.78 scores and 51.65 +/- 20.75 scores respectively, both were significantly higher than that of patients with mild LSS (26.57 +/- 15.85 scores, P < 0.05 and P < 0.01).
CONCLUSIONThe high incidence age of cyclomastopathy is under 40 years, and most of cyclomastopathy patients are classsified to LSS by TCM syndrome differentiation. So age and life event scores may be the objective bases for syndrome typing and liver stagnation syndrome grading in patients with cyclomastopathy.

Objective To investigate the expression of survivin and bcl-2 in human squamous cell carcinoma (SCC) lesions and cell line SCL-1. Methods Tissue samples from 60 patients with SCC and 10 normal human controls were immunohistochemically stained to detect the expressions of survivin and bcl-2.Western blot was used to measure the expressions of bcl-2 and survivin proteins in HaCaT human keratinocytes and SCL-1 human squamous cell carcinoma cells. Results In normal control tissues, there was no expressions of survivin or bcl-2, while in SCC, the expression rates of bcl-2 and survivin were 70% and 60%, respectively,and there was no statistical correlation between the expressions of bcl-2 and survivin (P >0.05). Neither the expression of survivin nor that of bcl-2 was correlated to patients' age, gender or lesional site (all P >0.05). A statistical correlation was observed between the pathological stage in patients and expression of bcl-2 as well as between lymph node metastasis and expression of survivin (both P < 0.05). Western blot analysis revealed a significant increase in the expression of survivin and bcl-2 in SCL-1 cells compared with HaCaT cells. Con-clusion In SCC, survivin and bcl-2 seem to play their roles via different anti-apoptotic pathways.

Objective To detect mutations of the ADAR1 gene in three Chinese families with dyschromatosis symmetrica hereditaria (DSH).Methods DNA was extracted from the blood samples of seven patients with DSH and their 33 relatives in three families with DSH as well as from 50 unrelated healthy controls.PCR and direct sequencing were performed to detect mutations in the ADAR1 gene.Results All the patients carried mutations in the ADAR1 gene.Three mutations were identified,including one frameshift mutation c.2433-2434delAG in family 2 and two missense mutations,i.e.,c.1760A > G (p.Y587C) in family 1 and c.3620G > T (p.G1207V) in family 3.No mutations were found in the ADAR1 gene in unaffected individuals in these families or the healthy controls.Conclusion Two novel missense mutations are found in the ADAR1 gene of two Chinese families,which may represent a molecular mechanism underlying the development of DSH.

In this paper 3 different media (A,for yeast cultivation ; B, for laccase producing; D, for white rot fungi cultivation) were compared in enriching and screening decolorizing fungi culture using Reactive Black 5 (RB5) and Reactive Red (M-3BE) from the following three points: decolorization effects, abilities of producing enzymes and diversity of microbial community. 11 groups of fungi with obvious decolorization effects were obtained after enrichment for near one month. Among them, 6 groups came from medium D, the other two 3 groups from medium A and B, respectively. However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae (Monascus went), Erysiphaceae and Physodermataceae. Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae (Penicillium) were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.
