Central serous chorioretinopathy (CSC)is a common eye disease characterized by macular serous retinal detachment.However,sometimes there are some atypical features,such as diffuse retinal pigment epitheliopathy,choroidal neovascularization (CNV),acute bullous retinal detachment,subretinal fibrosis,etc.Atypical CSC often is misdiagnosed because of its similar manifestations to polypoidal choroidal vasculopathy (PCV),inflammatory diseases such as Vogt-Koyanagi-Harada syndrome (VKH),et al.Furthermore,there are some other ophthalmic and systematic diseases which can cause serous retinal detachment and other atypical features.Nevertheless,the therapeutic regimens of these diseases are in great variation.In view of this,oculist should pay more attention to the differential diagnosis of CSC by fully understanding its clinical findings and concerning the general history including gluococorticoid administration.In this way,a precise diagnosis and correct management can be done.

The cure rate in acupuncture plus Tuina was 68.8%, which is higher than that in acupuncture group (27.8%) and that in Tuina group(28.6%), and the statistical management showed significant differences. Acupuncture combined with Tuina could enhance the therapeutic effect in the treatment of the subluxation of the small joints of the cervical vertebrae.

Objective RNA interference (RNAi) expression vector was constructed to inhibit the focal adhesion kinase(FAK)expression in colon carcinoma HT29 cells, and then the sensitivity of the cells to 5-fluorouracil (5-FU) was determined. Methods One specific pair of oligonucleotides with short hairpin and its negative control sequence were designed and synthesized based on FAK cDNA sequences, then they were inserted into pGenesil-l vector to generate the recombinant plasmids. After identification by the restriction endonuclease and DNA sequencing, the recombinant plasmids were transfected into HT29 cells by lipofectamine TM 2000. The stable transfected cells were selected in a medium containing geneticin G418. The change in FAK expression in HT29 cells before and after RNA interference was detected by reverse transcription and polymerase chain reaction (RT-PCR) analysis and SP immunocytochemistry technique. Sensitivity of HT29 cells to 5-FU was determined by MTT assay. Results The recombinant plasmids coincided completely with the designs in the restriction map and the sequence analysis. After FAK being targeted by RNA interference, immunocytochemistry showed the protein expression of FAK was reduced dramatically, and RT-PCR revealed FAK mRNA expression was down-regulated by 76.94% compared to that of untransfected cells. MTT assay also showed that the sensitivity of HT29 cells to 5-FU in transfected pGenesil-1-FAK vector cells was increased, while IC50 declined remarkably (P

Objective To investigate the antitumor activity of Gefitinib, a selected epidermal growth factor receptor-tyrosine kinase inhibitor, on human colorectal cancer cell lines in vitro, and to explore the relationship between the inhibitory effect of Gefitinib on cancer cells and the expression of epidermal growth factor receptor (EGFR). Methods The growth inhibitory effects of Gefitinib, which expressed as the half growth inhibition dose IC50, on colorectal cancer cells were assessed by MTT assay. EGFR mRNA expression was detected by reverse transcriptional PCR (RT-PCR). Western blot was used to determine the expression of EGFR protein as well as its phosphorylated forms (p-EGFR). Results Gefitinib inhibited growth of all the six colorectal cancer cell lines in vitro with an IC50 range from 6.5 to 172.7?mol/L. Lovo cell line, with an IC50 value less than 10?mol/L, was the most sensitive one to Gefitinib, HT29 and SW480 were moderate sensitive to 10?mol/L

Objective To study the NF-?B activity in colon carcinoma HT-29 and Lovo cells treated with different crude extracts of Abrotani herba obtained by column chromatography with macroporous resin.Methods The decoction of Abrotani herba absorbed by macroporous resin AB-8 was mounted into the column and then eluted with distilled water and 30%,50%,75% and 95% alcohol.To select appropriate concentrations for treatment,HT-29 cells were pretreated for 24 hours with each elution phase of the rude extracts in different concentrations(0,50,100,200,400 and 600?g/ml),and then their activity was detected by MTT.The HT-29 and Lovo cells were thereafter cultured in DMEM complete media respectively containing distilled water extract and 30%,50%,75% and 95% alcohol extracts in the concentrations as obtained by MTT assay,and the cells in control group were cultured in DMEM only.The cells were then harvested and the nucleic proteins were extracted for measurement with electrophoretic mobility shift assay(EMSA).Changes in NF-?B activity in HT-29 and Lovo cells treated with different concentrations of crude extracts were observed by EMSA.Results Viability of HT-29 cells treated with 400 and 600?g/ml crude extracts were significantly lower than those treated with 0-200?g/ml crude extracts(P0.05).Conclusion Crude extracts of Abrotani herba,extracted by column chromatography with macroporous resin and eluted with 30% alcohol,can inhibit NF-?B activity in colon carcinoma HT-29 and Lovo cells.

Objective To observe the inhibitory effect of Gefitinib,a selective oral epidermal growth factor receptor tyrosine kinase inhibitor,on the growth of human colon cancer cells,and investigate the relationship between the sensitivity of colon cancer cells to Gefitinib and PIEN expressions.Methods The inhibitory effects of Gefitinib on 6 kinds of colon cancer cells(Lovo,HCT116,HT29,Lsl74T,SW480 and SW620),the levels of PTEN mRNA in different colon cancer cells.and PTEN protein expressions in colon cancer cells were detected by MTT assay,RT-PCR and Westem blot,respectively.Results The inhibitory effects of Gefitinib on the 6 colon cancer cells in vitro varied a lot.When the concentration of Gefitinib was 1 μmol/L,LoVO cells had the most sensitivity to Gefitinib with an IC50＜10μmol/L;HT29 and SW480 had moderate sensitivity,and the IC50 ranged from 10 μnol/L to 100 μmol/L;HCT116,LS174T and SW620 were insensitive to Gefitinib,and their IC50＞100 μmol/L.All the colon cancer cell lines exhibited PTEN mRNA and protein expressions.Conclusions PTEN mRNA andprotein expressions might not be associated with the inhibitory effects of Gefitinib on the growth of colon cancer cells.The expression of PTEN can not be taken as the indication of the sensitivity of colon cancer cells to Gefitinib.

Objective To compare the effect of Buzhong Yiqi Decoction (BYD) containing different doses of Radix Astragali on fibulin-3 expression in the hemorrhoid tissues of stage Ⅲ internal hemorrhoids patients with spleen deficiency and sinking of qi, and to evaluate its therapeutic efficacy and possible mechanism. Methods Fifty-five qualified patients were randomly divided into control group(N = 15), Chinese medicine group 1(N =20), and Chinese medicine group 2(N=20). All of the 3 groups were treated with operation, and additionally, Chinese medicine group 1 was given BYD containing Radix Astragali 20 g, and Chinese medicine group 2 was given BYD containing Radix Astragali 50 g orally after operation. The scores of anal pendant expansion and anal prolapse were evaluated, and the expression level of fibulin-3 in the hemorrhoid tissues was detected by Western blot method. Results After treatment, the symptoms of anal pendant expansion and anal prolapse were improved in the 2 Chinese medicine groups (P < 0.05) , and the improvement of anal pendant expansion symptom in Chinese medicine group 2 was superior to that of Chinese medicine group 1(P<0.05). Compared with the control group, the expression level of fibulin-3 in the hemorrhoid tissues of the two Chinese medicine groups was increased (P < 0.05); the expression level of Chinese medicine group 2 showed an increasing trend as compared with that of Chinese medicine group 1, but the difference was statistically insignificant (P > 0.05). Conclusion BYD with large dose of Radix Astragali exerts stronger therapeutic efficacy for the treatment of prolapsed hemorrhoids than BYD with small dose of Radix Astragali, and its therapeutic mechanism has no obvious relation with promoting the increase of fibulin-3 expression.

The synchronous fluorescence spectra of myoglobin were studies for the first time. The fluorescence peaks observed in the spectra were assigned. When the wavelength interval (Δλ) is 80 nm, the main peak at 335 nm is originated from the tryptophan residues in the myoglobin molecule. When Δλis 20 mn, the peak at 308 nm is mainly due to the tyrosine residues in the myoglobin molecule and in a small part due to the tryptophan residues.Two peaks at 322 and 596 nm were observed in the spectrum of myoglobin for Δλ = 40 nm. The peak at 322 nm is due to both tyrosine and tryptophan residues. The peak at 596 nm is attributed to the heme group in the myoglobin molecule .
