Abstract?AIM:To investigate the clinical effect of orthokeratology for 400 juvenile with myopia astigmatism and its effects on corneal endothelial cells.?METHODS:Four hundred patients(800 eyes), of whom the average age was 11.5 ±2.3 years old, 239 male, 161 female, were divided into two groups: orthokeratology group and spectacles group. Parameters including efficacy data ( uncorrected visual acuity, corneal curvature, axial length and diopter ) and corneal endothelial cell data ( count of endothelial cell, endothelial cell density, fluorescein staining and central corneal thickness) were observed at 1d, 1, 6, 12 and 24mo after wearing.? RESULTS: The visual acuity of spectacles group recovered to normal after wearing, that of orthokeratology group recovered to normal at 1mo after wearing.At 2a after wearing, the corneal curvature, diopter of orthokeratology group decreased significantly (40.09 ±0.31D, 0.23 ±0.06D respectively); while those of spectacles group increased, the differences between the two groups were significant (P<0.05).The axial length of the two groups increased slightly at 1mo after wearing ( P>0.05 ) compared to those before wearing. At 2a after wearing, the axial length of the two groups were 23.96 ± 0.38mm, 26.49±0.88mm respectively (P<0.05).At 2a after wearing, central corneal thickness was 527.33 ± 27.69mm, 526.98±26.89μm(P>0.05).The count of endothelial cell and endothelial cell density both decreased after wearing without significant differences (P>0.05).?CONCLUSION: Orthokeratology has less effect on the corneal endothelial cells, no obvious adverse reactions and can control the prognosis of myopia.

Purpose To observe the mutation of K-ras gene and expression of Fascin-1 protein in CRC tissues and their relationship with clinical pathological features, and then to analyze the correlation between mutation of K-ras and expression of Fascin-1. Methods In 86 cases of CRC tissues, K-ras mutation was detected by DNA sequencing analysis, and Fascin-1 expression was detected by im-munohistochemical method. Results In CRC tissues the mutation rate of K-ras was 34. 88%, the expression rate of Fascin-1 was 60. 47%. The mutation rate of K-ras in lymph node metastasis group was higher than that of without lymph node metastasis group, and that in distant metastasis group was higher than that of without distant metastasis group(P<0. 05). The expression rate of Fascin-1 in serosa invasion group was higher than that of without serosa invasion group, and that in lymph node metastasis group was higher than that of without lymph node metastasis group, and that in distant metastasis group was higher than that of without distant metastasis group (P<0. 01). There was a correlation between the mutation of K-ras gene and the expression of Fascin-1 in CRC tissues (rp =0. 236, P<0. 05). Conclusions The CRC tissues with mutation of K-ras are more likely to metastasize and the CRC tissues with expression of Fascin-1 are more likely to invade serosa and metastasize. The CRC tissues with mutation of K-ras are more likely to express Fascin-1.

Objective： The current study was designed to investigate the expression of glutathione s-transferase π ( GST-π ) and its clinical significance in human primary transitional cell carcinoma(TCCs) of bladder. Methods： A total of 107 human primary bladder TCCs of the previously untreated patients were analyzed for expression of GST-π and P-glycoprotein (Pgp) by SP immunohistochemistry (IHC). Results： The GST-π positive staining were divided into three groups： single cytoplastic staining, single nuclear staining, both cytoplastic and nuclear staining. GST-π were present in 72.9％ generally, GST-π cytoplastic staining (single cytoplastic, both cytoplastic and nuclear staining) were found in 58.9％ of the samples, 46.7％ of them were positive nuclear staining (single nuclear, both cytoplastic and nuclear staining). GST-π general positive staining and cytoplastic positive staining were significantly correlated with grade, stage and recurrence after post-operative intravesical chemotherapy. Both of them were also strongly related to the expression of Pgp. While GST-π nuclear positive staining was related to stage but not with grade and recurrence. Conclusions： Overexpression of GST-π can be used as a predictive marker of post-operative intravesical chemotherapy in TCCs. Furthermore increased cytoplastic staining is a better predictor of drug resistance while increased nuclear staining might be associated with progression in TCCs.

Objective In order to study the difference of depression-like behaviours among three widelyused stress models in rats.Methods The new-born Spragne-Dawley rats were randomly divided into maternal deprivation(MD) group(n=27),chronic mild stress(CMS) group (n=29),dual stress(DS) group ( n=31 ) and control (C) group ( n =30) on postnatal day 1.MD rats only received maternal deprivation.CMS rats only received chronic mild stress when 10 weeks old.DS rats received both maternal deprivation and chronic mild stress.Control rats received no experimental handling.Behavior tests including forced swimming test and sucrose consumption which were carried out to evaluate rats' depression-like behaviors in the thirteenth weeks.The extend time of floating and sucrose preference ratio should be recorded in the forced swimming test and sucrose consumption test respectively to reflect the behavior of helplessness and anhedonia of rats.Results In the forced swimming test,the extend floating time of MD group( 119.30 ± 65.56) s,CMS group ( 145.00 ± 80.24) s and DS group ( 170.03 ±61.75 )s were longer than the control group(81.14 ± 52.40)s (F =11.53,P ＜ 0.01 ).In the sucrose consumption test,the MD group(0.32 ± 0.22) had a low sucrose consumption.The comparison of the MD group and CMS group (0.43 ± 0.28 ) to the control group (0.54 ± 0.28 ) had significant differences (F =4.33,P ＜ 0.01 ).In these four groups,no sexual difference was found in the forced swimming test and sucrose consumption test ( all P ＞ 0.05 ).Conclusion The results suggest that MD,CMS and DS may induce some kind of depression-like behaviors in rodents such as anhedonia or the behavior of helplessness and the depression-like behaviors induced by different stresses are similar in male and female individuals.

Objective To investigate the value of nerve conduction studies (NCSs),F wave analysis,somatosensory evoked potential (SEP) and skin sympathetic response (SSR) in the early diagnosis of diabetic peripheral neuropathy (DPN).Methods A total of 110 patients with diabetes mellitus were recruited as the diabetic group and another 50 well-matched healthy volunteers as the normal controls.Sensory and motor NCSs of the median,ulnar,posterior tibial and common peroneal nerves were performed.F waves were recorded from the median and posterior tibial nerves.SEPs elicited by stimulation to nerves of both the upper and lower limbs as well as SSRs were measured,all in both the diabetic group and the normal controls.Results The total rate of nerve conduction abnormality was 74.5％ in the diabetic group,with sensory nerve conduction abnormalities more frequent and more severe among motor nerves in the extremities.The total rate of F wave abnormalities was 57.3％ in the diabetic group.The rate in patients with normal distal motor conduction in their median and posterior tibial nerves was 50.7％.The total SEP abnormality rate was 70.0％ with regard to the proximal peripheral nerve potentials in the diabetic group,but there was no obvious abnormality of the supraclavicular electrical potential in the upper limbs for those with normal sensory nerve conduction in the median nerve.The rate of occurrence of abnormality in the gluteus point potential in the lower limbs of those with normal posterior tibial sensory conduction was 62.5％.The total rate of SSR abnormalities was 80.0％ in the diabetic group but 72％ among those with normal nerve conduction in their extremities.Combining the NCS,SSR,SEP and F wave results,the total abnormality rate was 90.9％ in the diabetic group,which was much higher than with any single test used alone.Conclusion NCS is essential for diagnosing DPN.Early diagnosis of subclinical diabetic neuropathy will be significantly enhanced when nerve conduction,SSRs,SEPs and F waves are tested together.
