Objective To explore the relationship between retinal nerve fiber layer (RNFL) thickness and central corneal thickness (CCT) in myopia eyes.Methods 91 cases (91eyes) were selected from ophthalmological outpatients including 28cases with low myopia ( spherical equivalence [ SE ] ＞ -3.0D), 33 cases with moderate myopia (SE -0.3D ～ -6.0D) and 30 cases with high myopia (SE ＜ -6.0D).All patients received ocular standard examination including intraocular pressure, refraction, slitlamp biomicroscopy and fundus examination.Other ocular diseases except refractive error were excluded.RNFL thickness and CCT were measured by RTVue Fourior-OCT ( Optovue Inc, USA).Refraction diopter was shown as SE.Results The mean RNFL thickness and CCT was ( 108.5 ± 10.1 ) μm, (524.7 ±36.8)μm respectively.These were no significantly different among low, moderate and high myopia ( P ＞ 0.05 ).Temporal RNFL thickness( tl1 ,tu1 ) was significantly positive related with CCT( r =0.281,0.093 of tl1, r= 0.352,0.167 of tu1 respectively in single and multiple variable analysis; P ＜ 0.05 ), nasal ( nl2, nu2)and inferior nasal RNFL thickness( in2,in1 )was significantly positive related with SE( P ＜0.05), inferior temporal RNFL thickness( it2)was significantly negative related with SE( P ＜0.05), and RNFL thickness in other regions were not significant related with CCT and SE ( P ＞ 0.05 ) in single and multiple variable regressive analysis.Conclusion Relationship between RNFL thickness of local paradisc region and CCT in myopia eyes suggested that CCT should be correlative with some sensible structural parameters in glaucomatous neuropathy and might be important in the diagnosis and therapy of glaucoma.

Scatchard, pseudoscatchard and competitive analyses showed that there were two glucocorticoid (GC) binding sites in rat hepatic cytosol: high-affinity glucocorticoid binding sites (HAGS) and low-affinity glucocorticoid binding sites (LAGS). Pseudoscatchard analysis showed the dissociation constant (Kd) of LAGS was 4.1+1.4umol/L (n=4). The inactivation of LAGS in vitro was slower" than that of HAGS. LAGS and HAGS could not be separated by DEAE-cellulose chfomatography. HAGS were saturable and had steroid specificity for glucocorticoid just as the classic glucocorticoid receptor. Triamcinolone acetonide, RU486 and RU26988 competed equally well to LAGS while aldosterone, progesterone, estradiol and testosterone did not compete with LAGS. These results suggest that LAGS have steroid specificity for glucocorticoids. The biological actions of LAGS await fur ther study.

Purpose:To study the connection between the blocking of N-acetylglucosaminyltransferase V(GnT-V) and endoplasmic reticulum stress(ER stress). Methods:The recombinant plasmid expressing siRNA of GnT-V was constructed and transfected into SMMC-7721. The key molecules such as GRP78,XBP1 and PERK during ER stress was analyzed in mRNA and protein levels. Results:GRP78 mRNA and protein levels were upregulated, the spliced forms of XBP1 mRNA and protein appeared and ER eIF2? kinase PERK was activated. Conclusions:These results suggest the blocking of GnT-V in SMMC-7721 induces cellular ER stress.

Dysregulation of cell metabolism, especially glucose metabolism, is implicated in tumorigenesis and tumor progression.Cancer cells uptake a large amount of glucose and prefer to perform glycolysis in the cytosol even under normal oxygen condition, which fuels fast cell growth and proliferation.Dysregulation of glucose metabolism leads to tumorigenesis and promotes cancer development.Conversely, the initiation and development of cancer reprograms glucose metabolism to confer cancer cells the ability to survive and proliferate.Oncogenes, tumor suppressors or non-coding RNAs could regulate glucose metabolism.Meanwhile, the enzymes and metabolites involved in glucose metabolism could regulate the expression of factors related to cancer.Enzymes, the direct executor of cell metabolism, play a key role in dysregulation of glucose metabolism, tumorigenesis and tumor development.

Objective To observe the effect of salt-partitioned moxibustion at Zhongwan (CV12) in treating belching due to chemotherapy.Method Subjects with chemotherapy-induced belching were randomized into an observation group and a control group, 30 in each group. The control group was intervened by intramuscular injection with Ritalin 20 mg, while the observation group was by salt-partitioned moxibustion at Zhongwan for 30 min in addition to the intramuscular injection.Result The total effective rate was 93.3% in the observation group versus 76.7% in the control group, and the difference was statistically significant (P＜0.05); the action latency in the observation group was (1.7±1.8)min in the observation group versus (15.6±4.2)min, and the difference was statistically significant (P＜0.01).Conclusion Salt-partitioned moxibustion at Zhongwan is significantly effective in treating chemotherapy-induced belching, and it’s easy-to-operate, efficient, and safe.

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.
