Toll-like receptor is a receptor to identify the pathogen associated molecular,which relates the natural immune with required immune.Toll-like receptor activates natural immune and induces several cytokines.As a result,it will influence the differentiation of initiated T-cell by identifying Pathogens.The main Tolllike including TLR2、3、4、7、8、9 are closely related with anti-rotavirus to identify the natural immune affection of rotavirus.This review to explain the pathogenesis of Toll-like in rotavirus infection,as well as the key role which Toll-like plays in preventing rotavirus infection and controlling the inflammation.

Objective To explore the difference of efficacy between LEEP and microwave treatment on chronic cervicitis.Methods According to the different treatment method,400 patients with chronic cervicitis were divided into LEEP group (LEEP treatment) and microwave group (microwave treatment),each group 200 cases.The treatment time,amount of bleeding and the healing effect between the two groups were compared and analyzed.Results The operative time,amount of bleeding before and after operation,vaginal fluid time after surgery of LEEP group were (6.94 ± 1.13) min,(2.13 ± 0.32) ml,(15.23 ± 3.40) mi,(7.06 ± 1.47) d,which were better than those of the microwave group[(16.13 ± 2.81) main,(5.94 ± 1.45) ml,(50.06 ± 7.86) ml,(17.58 ± 4.33) d] (t =42.91、36.29、57.52、32.54,all P ＜ 0.05).The number of recovery patients had no statistically significant differences in mild,moderate patients of the two groups(97 cases vs 104 cases and 54 cases vs 45 cases,χ2 =0.81,1.35,all P ＞0.05),and the number of recovery patients in the LEEP group was better than that in the microwave group(23 cases vsl4 cases,χ2=6.87,P ＜ 0.05).Conclusion The efficacy of LEEP knife on chronic cervicitis was significantly.It has a less operative time,less blood loss,better recovery.It is worthy of promotion.

BACKGROUND: The effect and mechanism of peroxisome proliferator-activated receptor gamma (PPARγ) agonists on transforming growth factor (TGF)-β1-induced fibrotic responses in lung fibroblasts remain unclear, and seldom reported.OBJECTIVE: To study the effects of PPARγ agonists on TGF-β1-induced fibrotic responses in lung fibroblasts, so as to investigate its effects in preventing pulmonary interstitial fibrosis of silicosis. METHODS: The pulmonary alveolar macrophage was prepared with 200 mg/L SiO2 and the supernatants were got. Chinese hamster lung fibroblasts were incubated with the prepared supernatants. Then a cellular model in vitro for studying pulmonary fibrosis induced by SiO2 was developed. Chinese hamster lung fibroblasts were cultured to observe the effects of the PPARγ ligand (15 d-PGJ2) and its agonists (troglitazone and ciglitazone) on the expression of TGF-β1-induced fibronectin. RT-PCR was used to detect the mRNA expression of fibronectin and Western blotting was used to detect the protein expression of fibronectin. RESULTS AND CONCLUSION: (1) The expression of TGF-β1 mRNA showed an effect in a dose- (0-5 μg/L) and time- (0-24 hours) dependent manner. (2) PPARγ ligands and agonists reduced the mRNA and protein expressions of fibronectin. Results suggested that PPARγ agonists can inhibit TGF-β1-induced fibronectin synthesis after stimulation by SiO2 and may play a potential role in preventing pulmonary interstitial fibrosis.

Objective To observe the clinical efficacy and adverse drug reactions of three dimensional-conformal radiotherapy combined with oral capecitabine in the treatment of stage Ⅱ , Ⅲ rectal cancer after operation. Methods Sixty-three patients of stage Ⅱ ,Ⅲ rectal eancer after operation with informed consent were divided into two groups by random digits table, 33 cases of observation group were treated by three dimensional-conformal radiotherapy combined with oral capecitabine, 30 cases of control group were treated by three dimensional-conformal radiotherapy only. Results The total effective rate in observation group was 84.8% (28/33), it was higher than that in control group [63.3% (19/30)], the difference between the two groups was statistically significant (P < 0.05). The occurrence rate of adverse reactions in two groups were compared, the difference was not statistically significant [57.6%(19/33) vs.50.0% (15/30)] (P>0.05). Conclusion Three dimensional-conformal radiotherapy combined with oral capecitabine in the treatment of stage Ⅱ,Ⅲrectal cancer after operation has satisfactory effect and acceptable adverse reaction, it is worth generalizing and applying.

BACKGROUND:Several studies have confirmed that bone marrow mesenchymal stem celltransplantation exerts a certain neuroprotective role in cerebral infarction. Edaravone is a novel potent smal-molecule hydroxyl radical scavenger, which play a protective role in the brain by eliminating free radicals and inhibiting nerve celldamage after cerebral infarction. OBJECTIVE:To explore the influence of bone marrow mesenchymal stem cells combined with edaravone on expressions of aquaporin-4, Bcl-2, and brain-derived neurotrophic factor after cerebral infarction in rats. METHODS:Eighty Wistar rats were selected to establish models of cerebral infarction by right middle cerebral artery occlusion, and then randomly divided into control group, bone marrow mesenchymal stem cells group, edaravone group and edaravone+bone marrow mesenchymal stem cells group (combination group). After 6 hours of modeling, rats from these four groups were respectively injected via the tail vein with PBS, bone marrow mesenchymal stem cells, edaravone and edaravone+bone marrow mesenchymal stem cells. After 72 hours, the rats were decapitated to take brain tissues. Consequently, expressions of aquaporin-4, Bcl-2, and brain-derived neurotrophic factor mRNA and protein were determined by RT-PCR and western blot methods. After 12, 24 and 36 hours, TUNEL method was used for the determination of cellapoptosis. RESULTS AND CONCLUSION:The expressions of Bcl-2 and brain-derived neurotrophic factor were higher in the combination group than the other three groups (P<0.05), but the expression of aquaporin-4 was lowest in the combination group (P<0.05). The number of apoptotic cells in the combination group was significantly lower than that in the other three groups. These findings suggest that the combination of bone marrow mesenchymal stem cells and edaravone can improve expressions of Bcl-2 and brain-derived neurotrophic factor in the injured site, and significantly inhibit neuronal apoptosis. Meanwhile, the combination therapy can decrease expression of aquaporin-4 and mitigate cerebral edema, which is superior to bone marrow mesenchymal stem celltransplantation and edaravone alone.
