Objective To study the effect of SDF1/CXCR4 and FN/?1 integrin modulated by curcumin on the adhesion and migration of B lymphoma Raji cell and to explore the mechanism of curcumin to inhibit the invasiveness of lymphoma.Methods The experiment consisted of eight groups: Control,FN,SDF,FN+anti-?1 integrin,SDF+anti-CXCR4,curcumin+FN,curcumin+SDF.Adhesion assay and migration assay were used to detect the difference of invasiveness among different groups.Results In vitro,SDF1 and FN can increase the adhesion and migration of Raji cells,which can be blocked by ?1 integrin antibody and CXCR4 antibody.Curcumin can inhibit the adhesion and migration of Raji to FN in a dose-dependant manner.Low dosage curcumin had minimal effect on the adhesion and migration of Raji induced by SDF except that 25?mol/L curcumin can inhibit the adhesion and migration of Raji.Conclusion FN/?1 integrin and SDF1/CXCR4 pathway play important roles in the adhesion and migration of Raji cells.Curcumin can decrease the invasiveness of Raji cells through inhibiting FN/?1 integrin.It has good prospect of clinical application.

AIM:To explore the application of 10g/L cyclopentolate chloride eye drops in children, and to compare the different effectiveness of cycloplegia between 10g/L cyclopentolate chloride and atropine in Chinese children.METHODS:A total of 236 eyes of 118 children aged 3~12 years old were enrolled in this study including 80 eyes of 40 children with myopia, 156 eyes of 78 children with hyperopia and 146 eyes of 73 children combined with astigmatism. 10g/L cyclopentolate chloride eye drops were used once per 5min for 3 times and refractive diopter was obtained 1h after the last drop of cyclopentolate. Three days after that, 10g/L atropine was then used 1 time per night for 1wk and optometry was performed again. The children were divided into 3 groups ( myopia, hyperopia and astigmatism group ) according to the refractive status, in which astigmatism was independent of the degree of separation of cylinder statistics. The results of retinoscope refraction were then compared between 10g/L cyclopentolate and 10g/L atropine.
RESULTS:The refractive diopter was -2. 25±1. 31D after 10g/L cyclopentolate eye drops and -2. 23±1. 32D after 10g/L atropine in myopic group. The refractive diopter was 1. 35±1. 19D and 1. 38±2. 00D in astigmastic group. No significant difference was found in myopic group and astigmastic group (P= 0. 109, P= 0. 374). While in the hyperopic group, the refractive diopter was 3. 76±2. 4D after 10g/L cyclopentolate eye drops, which was lower than that after 10g/L atropine 4. 39±2. 6D (P=0. 000).
CONCLUSION: The results of this study suggest that 10g/L cyclopentolate chloride eye drops can be used in myopia and astigmatism children, and 10g/L atropine should be used in hyperopia children.

OBJECTIVETo analyze the reversal effect of Buzhong Yiqi Decoction (BYD) on multidrug resistance of human adenocarcinoma of lung cell line A549/DDP, and to study its effect on the expression of survivin by using serum pharmacological methods in vitro. Methods Totally 24 SD rats were divided into the high, medium and low dose groups, and the blank control group by randomized controlled method. The high dose BYD containing serum (1. 134 g/mL, 2 mL), the middle dose BYD containing serum (0.576 g/mL, 2 mL), and the low dose BYD containing serum (0.284 g/mL, 2 mL) were prepared. The inhibitory effects of different dose and concentrations BYD on the proliferation of A549 and A549/DDP cells were detected by MTT assay, and the drug resistance reversal fold was calculated. The expression of Survivin in the two cell strains were detected respectively by immunohistochemical assay, Western blot, and immunofluorescence method.

RESULTSBYD containing serum showed obvious inhibitory effect on the growth of A549 and 549/DDP. The inhibition rates of 10% dose groups were higher than those of 5% dose groups. Besides, it gradually increased along with increased concentrations. Compared with 10% blank control group, the inhibition rate increased in 10% middle and low dose groups (P <0.05). After acted with 10% middle dose BYD containing serum, IC50, of A549 and A549/DDP were both reduced (P <0.05), reversal fold (RF) both increased. Its reversal ratio on A549/DDP cells was 2. 46, decreasing the resistance of A549/DDP to DDP. Compared with A549 in the same group, the expression of Survivin was detected to decrease by immunocytochemical assay, Western blot, and immunofluorescence method (P<0.05). Compared with 10% blank control group, the inhibition rate decreased in 10% middle dose group (P <0. 05).

CONCLUSIONS10% middle dose BYD containing serum could significantly inhibit the apoptosis of A549 and A549/DDP. Besides, it could moderately reverse the multidrug resistance of A549/DDP cells to DDP possibly through reducing the intracellular expression of Survivin and enhancing the sensitivity 549/DDP to chemotherapeutics.

OBJECTIVETo investigate the relationship of tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor beta1 (TGF-beta1) with the occurrence of ankylosing spondylitis (AS), and the effects of Bushen Tongdu Decoction (BTD) on serum TNF-alpha and TGF-beta1, levels in patients.

METHODSSeventy five AS patients were assigned to two groups, 30 in the group I treated with Azulfidine and35 in the group II treated with BTD. ELISA was adopted to detect the levels of TNF-alpha and TGF-beta1, in patients before and after 24-week treatment. Meantime, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured as well. Besides, the levels of TNF-alpha and TGF-beta1 in 30 healthy persons were also detected for normal control.

RESULTSBefore treatment, as compared with normal control, the TNF-alpha increased and TGF-beta1 decreased (P < 0.01) in the two treatment groups; the serum level of TNF-alpha was positively correlated with ESR and CRP (r = 0.296, r = 0.249; P < 0.05), but the serum level of TGF-beta1 showed no correlation with them (r = -0.222, r = -0.203; P > 0.05). After treatment, TGF-beta1 increased, while TNF-alpha, CRP and ESR decreased in group II (P < 0.01).

CONCLUSIONBTD can regulate TNF-alpha and TGF-beta1 levels to suppress the immune inflammatory reaction so as to treat AS.

β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.001). The results of the experiment proved that different β-AS genotypes at 94 bp site from different regions may be one of the important reasons to result in the genuineness of Glycyrrhiza uralensis.
