Previous studies showed that three methods for regulating and invigorating lung and kidney (lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, and Qi supplementing and kidney nourishing) could regulate inflammatory signaling pathways of chronic obstructive pulmonary disease (COPD) in rats, so as to alleviate inflammation. In the present study, R-value comprehensive evaluation method was used to evaluate the comprehensive effect of three methods for regulating and invigorating lung and kidney on inflammatory signaling pathways. Rats were randomly divided into control, model, lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline groups. The COPD rat models were established by cigarette smoking combined with bacterial infection, and orally administered with drugs between the 9th and 20th week. Afterwards, efforts were made to observe the long-term effects between the drug withdrawal and the 32rd week and detect indicators in two batches in the 20th week and 32th week. Specifically, (1) Linking JAK/STAT signaling pathway: JAK2 mRNA, and protein expressions of STAT-1, STAT-3, STAT-5, JAK-2; (2) NF-kappaB signaling pathway: Smad2 mRNA and protein expressions of I-kappaB, NF-kappaB, TGF-beta1; (3) PPARgamma and antioxidant signaling pathway: SOD, PGE mRNA, PPARgamma protein. According to the results, 5 indicators in JAK/STAT pathway, 4 indicators in NF-kappaB pathway, and 3 indicators in PPARgamma pathway were significantly rectified by three methods for regulating and invigorating lung and kidney in between the 20th week and 32nd week. Between the 20th and 32nd week, the recipes for rectifying JAK/STAT pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, Qi supplementing and kidney nourishing, lung invigorating and kidney tonifying, aminophylline, particularly those for lung invigorating and spleen strengthening; The recipes for rectifying NF-kappaB pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline, particularly the first three types of drugs. The recipes for rectifying PPARgamma and antioxidant signaling pathway with intensity from high to low were recipes for lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing, lung invigorating and spleen strengthening and aminophylline. Therefore, three methods for regulating and invigorating lung and kidney showed better long-term effects in regulating COPD lung inflammation signaling pathways. Specifically, recipe for lung invigorating and spleen strengthening showed a better effect in JAK/STAT and NF-kappaB pathways, while recipe for lung invigorating and kidney tonifying and Qi supplementing and kidney nourishing showed better effects in PPARgamma and antioxidant signaling pathways. In conclusion, R-value comprehensive evaluation method can evaluate the comprehensive effect of medicines and define the ranking of multiple drugs and their main targets.

OBJECTIVETo evaluate the efficacy and safety of etanercept plus Tripterygium wilfordii polyglycoside (TWP) in elderly patients with active rheumatoid arthritis (RA).
METHODSTotally 46 elderly patients with active RA were randomly assigned to the treatment group (22 cases) and the control group (24 cases). All patients received subcutaneous injection of etanercept, 25 mg each time, twice per week. The dosage was reduced to once per week 3 months later. Patients in the treatment group took TWP Tablet (10 mg each time, three times per day), while those in the control group took methotrexate (MTX), 10 mg each time, once per week. The whole course lasted for 24 weeks. Patients' rest pain, tender joint number, swollen joint number, health assessment questionnaire (HAQ), patients' global assessment, physicians' global assessment, erythrocyte sediment rate (ESR), C reactive protein (CRP), rheumatic factor were assessed at week 0, 4, 8, 12, and 24. The curative effect was statistically evaluated by the United States Institute of Rheumatology ACR20, ACR50, and ACR70 improvement criteria. Meanwhile, any adverse event was recorded and evaluated.
RESULTSTotally 41 completed the trial, and 5 dropped off (3 in the treatment group and 2 in the control group). Compared with the control group, there was no statistical difference in ACR20, ACR50, or ACR70 in the treatment group (P > 0.05). Compared with before treatment in the same group, there was some improvement in tender joint number, swollen joint number, visual analogue scale (VAS) for patients' global assessment, VAS for physicians' global assessment, ESR, CRP, and HAQ between the two groups, showing statistical difference (P < 0.05). Compared with the control group in the same phase, there was no statistical difference in the treatment group (P > 0.05). There was no statistical difference in the occurrence of adverse events between the two groups.
CONCLUSIONSEtanercept plus TWP could achieve equivalent therapeutic effect to that of Etanercept plus MTX. The two regimens could improve clinical signs, symptoms, and QOL related to RA. They were well tolerated in the treatment of elderly patients with active RA.

BackgroundOur previous study showed that erythropoietin (EPO) protects the photoreceptor from apoptosis in retinal detachment(RD) rat,but its signal transduction pathway remains unknown.Objective The present study was to investigate the effects of EPO on signal transduction pathway in RD.MethodsTwentyfour albino clean Sprague-Dawley(SD) rats were randomly divided into 4 groups.5 μl PBS was injected into vitreous cavity of rats in RD+PBS group,and 400 ng EPO(5 μl) was used at the same way in RD+EPO group.Three days later,the rats were sacrificed and the retina was isolated in each group.The expression levels of Janus kinase 2 (JAK2),p-JAK2,Akt,p-Akt,extracellular regulated protein kinase-1/2 ( ERK-1/2 ),p-ERK-1/2,signal transducer and activator of transcription 5 ( STAT5 ),p-STAT5,nuclear factor-kB (NF-sB) and p-NF-kB were detected by Western blot assay.The administration of experimental animals followed the Standard of ARVO.ResultsThree days after RD,the expression levels of JAK2,Akt and ERK-1,ERK-2 in retinas among normal group,RD,RD+PBS,RD+EPO groups were statistically insignificant different ( F =0.298,P =0.826 ; F =0.681,P =0.588 ; F =0.978,P=0.450;F=1.115,P=0.399 ),but the levels of p-JAK2,p-Akt,p-Erk-1 and p-Erk-2 among these 4 groups were significant difference ( F=24.435,P =0.000; F=48.163,P =0.000;F =19.092,P =0.001; F =14.393,P=0.001 ),and those in RD+EPO group was significantly higher than that in RD and RD+PBS groups( P<0.05 ).The expression levels of STAT5 and NF-kB among the 4 groups were no significantly differences (F =1.136,P=0.391 ;F=0.696,P=0.580),but after the phosphorylation of STAT5 and NF-kB,the differences was significant ( F =14.189,P =0.001 ; F =40.103,P =0.000 ).Those in RD,RD + PBS,RD + EPO groups did not increase either (P>0.05).Although the levels of p-STAT5 and p-NF-kB in RD,RD+PBS,RD+EPO groups were significantly higher than those in normal control group( P<0.05 ),the level of p-STAT5 in RD+EPO group was not significantly higher than that in RD and RD + PBS groups (P > 0.05 ). Conclusions PI3K/Akt and MAPK/ERK-1/2 signal transduction pathways might participate in the protecting process of EPO to photoreceptor in RD rats.

OBJECTIVE:
To explore the change rules of peak area ratio of STR loci to Amelogenin (AMEL) locus (STR/AMEL), a sex-determining gene in DNA degradation, and to evaluate the application of STR/AMEL value in the estimation of DNA degradation degree.
METHODS:
DNA was extracted from iliopsoas, and the variations of STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) were analyzed after the artificial degradation was made by DNase I, and the changes of these three ratios of the iliopsoas naturally degraded in an outdoor environment were also analyzed. The regression curves were analyzed using the periods of DNA degradation and outside the body as the independent variable (x) and the STR/AMEL value as the dependent variable (y) and three curve equations under two conditions were established.
RESULTS:
Both under the conditions of artificial and natural degradation, STR/AMEL value had a negative relationship with the degradation time. The relationship between STR/AMEL and degradation time can be well simulated by the cubic function. R2 was over 0.99 under controlled degradation condition and over 0.86 under natural degradation condition.
CONCLUSION
The STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) is negatively related with the DNA degradation degree, which follows mathematical regression models strictly, and it might be applied to evaluate the DNA degradation degree.
