Objective To observe the effect ofTripterygium Wilfordii Hook. F. andTripterygium Hypoglaucum (Lévl.) Hutch on macrophage inflammatory factor, and to provide the oretical basis and experimental basis for the clinical application of these drugs.Methods Two batches ofTripterygium Wilfordii Hook. F. andTripterygium Hypoglaucum (Lévl.) Hutch were collected, and then the samples turned into alcohol extract by extraction and isolation. The IC50values of alcohol extracts were measured by MTT in BMDM cell. BMDM cell induced by the 4 batches of samples with IC50, then IL-6, IL-10, iNOS were detected by Elisa. Results The content of IL-6 (5.08 ± 0.96 pg/ml, 6.24 ± 0.20 pg/mlvs. 7.92 ± 0.84 pg/ml) and iNOS (0.14 ± 0.04 ng/ml, 0.36 ± 0.11 ng/mlvs. 0.86 ± 0.13 ng/ml) in Anhui and Guizhou groups were significantly lower than sulfasalazine (P<0.05), and the content of IL-10 (21.20 ± 4.24 pg/ml, 26.49 ± 4.44 pg/mlvs. 9.06 ± 0.40 pg/ml) in Anhui and Guizhou groups were significantly higher than sulfasalazine (P<0.05). The content of IL-6 (4.22 ± 0.38 pg/ml, 4.55 ± 0.44 pg/mlvs. 7.92 ± 0.84 pg/ml) and iNOS (0.07 ± 0.04 ng/ml, 0.28 ± 0.10 ng/mlvs. 0.86 ± 0.13 ng/ml) in Hunan and Zhejiang groups were significantly lower than sulfasalazine (P<0.05) .Conclusion The anti-inflammatory effect ofTripterygium WilfordiiHook. F. treat rheumatoid arthritis is better than sulfasalazine andTripterygium Hypoglaucum (Lévl.) Hutch.

Objective To compare the effects of selenium nanoparticles (Nano-Se) and sodium selenium (Na2SeO3) on apoptosis and reactive oxygen species (ROS) of articular chondrocytes from patients with Kashin-Beck Disease (KBD) in vitro,and provide a scientific basis for preventing KBD.Methods The subjects with KBD were diagnosed on National Clinical Diagnostic Criteria of KBD (WS/T207-2010),articular cartilage from 8 patients undertaken joint replacement operation were collected.In vitro,chondrocytes were treated with concentration of 0,25,50,100,200,300,400 and 500 μg/L of Nano-Se and Na2SeO3 for 5 d,respectively.Cell growth was detected by MTT assay,and the highest concentration and time corresponding to the highest survival rate of Nano-Se and Na2SeO3 were used in the following experiment.KBD chondrocytes were treated with Nano-Se and Na2SeO3,and divided into control group,Na2SeO3 group,Nano-Se group according to the randomized design.Each group had 8 cases.The cell apoptosis and ROS were detected by flow cytometry.Results The optimal intervention concentration of Nano-Se and Na2SeO3 was 100 and 400 μg/L,respectively.The optimal intervention time of NanoSe and Na2SeO3 both was 3 days.There was a significant decrease in the total and terminal apoptosis,ROS level of chondrocytes in Nano-Se group [(4.67 ± 0.89)％,(1.51 ± 0.48)％,(56.04 ± 4.81)％] and Na2SeO3 group [(7.07 ±0.25)％,(4.37 ± 0.37)％,(87.13 ± 6.60)％] compared with those of control group [(9.95 ± 0.38)％,(6.93 ± 0.42)％,(125.17 ± 16.60)％,all P ＜ 0.01].The difference of early apoptotic rate among control group,Na2SeO3 group,NanoSe group [(3.02 ± 0.41)％,(2.7 ± 0.46)％,(3.16 ± 0.56)％] was not statistically significant (F =2.11,P =0.35).Conclusion Appropriate concentration of Nano-Se can significantly decrease oxidative stress of KBD chondrocytes and inhibit apoptosis compared to Na2SeO3.

Objective To observe the effect of different regions of tripterygium hypoglaucum (Lévl.) hutch on macrophage inflammatory factor, and to providetheoretical basis and experimental basis for the clinical application of tripterygium hypoglaucum (Lévl.) hutch. Methods 5 batches of tripterygium hypoglaucum (Lévl.) hutch were collected, then the samples turned into alcohol extract by extraction and isolation. The IC50 values of alcohol extracts were measured by MTT in BMDM cell. B MDM cell were induced by the 5 batches of samples with IC50, then IL-6, IL-10, iNOS were detected by Elisa. The efficacy of different regions of tripterygium hypoglaucum (Lévl.) hutch on macrophage inflammatory factor was evaluated by comparison with sulfasalazine. Results The content of IL-6 (4.22 ± 0.38 pg/ml, 4.55 ± 0.44 pg/ml vs.7.92 ± 0.84 pg/ml) and iNOS (0.07 ± 0.04 ng/ml, 0.28 ± 0.10 ng/ml vs. 0.86 ± 0.13 ng/ml) in HuNan and ZheJiang groups were significantly lower than sulfasalazine (P<0.05), and the content of IL-10 (19.34 ± 6.06 pg/ml, 24.34 ± 3.03 pg/ml vs. 9.06 ± 0.40 pg/ml) in Guizhou and Fujian groups were higher than sulfasalazine (P<0.05). Conclusion The anti-inflammatory effect of HuNan and ZheJiang's tripterygium hypoglaucum (Lévl.) hutch treat rheumatoid arthritis is better than sulfasalazine, so theyaregenuine regional drug in the treatment of rheumatoid arthritis. Additional research will analyze associations between tripterygium hypoglaucum (Lévl.) hutch and rheumatoid arthritis.

?AIM:To compare the changes of the contrast sensitivity after LASIK with femtosecond laser and microkeratome and to explore the influence of different methods making corneal flap on visual quality.? METHODS: There were 212 eyes in 106 myopes underwent excimer operation . According to the different methods of operation, they were divided into two groups:microkeratome group ( SBK group ) and femtosecond laser group ( FS group) . FS group: a total of 112 eyes in 56 patients received LASIK with femtosecond laser. SBK group: a total of 100 eyes in 50 patients received LASIK with microkeratome. Contrast sensitivity was detected preoperatively, and 1wk, 3mo postoperatively and compared between the two groups.? RESULTS: At 1wk after operation, the contrast sensitivity under photopic environment decreased in the two groups, compared with those before operation ( P<0. 05). The differences of contrast sensitivity before and 3mo after operation were not significant (P>0. 05). No statistical significant difference was found in contrast sensitivity under photopic environment at 1wk, 3mo between the two groups ( P>0. 05 ). At 1wk after the operation, the contrast sensitivity under scotopic environment decreased in both groups compared with those before operation ( P< 0. 05 ). In SBK group, it decreased more than in FS group (P<0. 05). After 3mo, the decline of 14. 2c/d spatial frequency contrast sensitivity under scotopic environment in the SBK group was more than other frequency. No statistical significant difference was found in the rest frequency contrast sensitivity under scotopic environment before and after operation (P>0. 05). After 1wk, contrast sensitivity with glare stimulation in both groups decreased, compared with those before operation ( P< 0. 05 ), while in SBK group, it decreased more than in FS group (P<0. 05). After 3mo, except that the decline of 14. 2c/d spatial frequency contrast sensitivity with glare stimulation in the SBK group was significant compared with those before operation, the contrast sensitivity under glare stimulation in both groups had no significant differences compared with before operation(P>0. 05).?CONCLUSION:LASIK with femtosecond laser can get a better visual quality than LASIK with microkeratome.
