On the day before the rats were killed, those in TGP or colchicine groups received TGP or colchicine as above from the first day of tail vein injection of human albumin. The rats in normal and model groups were only administered with the same volume of vehicle. At the end of the 16th wk, rats in each group were killed. Blood and tissue specimens were taken. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), nitric oxide (NO), content of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px), were measured by biochemical methods. Serum procollagen type Ⅲ (PC Ⅲ) and laminin (LN) were determined by radioimmunoassay. Liver collagen level was determined by measuring hydroxyproline content in fresh liver samples. Hepatic tissue sections were stained with hematoxylin-eosin and examined under a light microscope.RESULTS: Histological results showed that TGP improved the human albumin-induced alterations in the liver structure, alleviated lobular necrosis and significantly lowered collagen content. The antifibrotic effect of TGP was also confirmed by decreased serum content of LN and PCⅢ in TGP-treated group. Moreover, the treatment with TGP effectively reduced the hydroxyproline contentin liver homogenates. However, the level of ALT and AST increased in fibrotic rat but had no significance compared with normal control, whereas the ratio of A/G decreased without significance. TGP had no effect on level of ALT, AST and the ratio of A/G. Furthermore, TGP treatment significantly blocked the increase in MDA and NO, associated with a partial elevation in liver total antioxidant capacity including SOD and GSH-px.CONCLUSION: TGP has beneficial effec展开更多

Methods： A total of 120 patients were assigned to two groups by lottery, 65 in the treated group and 55 in the control group. They all were orally treated with citirizine tablet 10 mg per day, but to the treated group, additional 0.2 g TGPC was given three times per day, the therapeutic course for both groups was 4 weeks. The effectiveness of treatment was observed, and the changes of total symptom score, serum levels of interleukin-4 （IL-4）, and immunoglobulin E （IgE） were measured before and after treatment. Moreover, a follow- up was carded out one month after ending the treatment. Results： The dropped cases were two in the treated group and seven in the control group; so, the study was accomplished on 63 patients in the treated group and 48 patients in the control group. The total effective rate was assessed at 73.02% （46/63） in the treated group, which was significantly higher than 47.92% （23/48） in the control group （P〈0.01）. After treatment, the total symptom score decreased in both groups, but the decrement in the treated group was more significant （P〈0.05）. Serum levels of IL-4 and IgE in the treated group lowered significantly, while the changes in the control group were insignificant, so statistical significant differences were shown between groups （P〈0.01）. A follow-up study showed that the relapse rate in the treated group was 30.00% （6/20）, while that in the control group was 90.00% （9/10）, and the former was lower than the latter （P〈0.01）. Adverse reactions, revealed as drowsiness, dizziness, and weakness, were seen in eight cases and seven cases in the two groups, respectively. Besides, mild diarrhea occurred in two cases of the treated group. Conclusions： The treatment of TGPC combining citirizine shows definite curative effect in treating chronic urticaria, with low relaps展开更多

Methods： A total of 86 outpatients were randomly allocated into two groups of TGPC （treatment, 44 cases） and compound glycyrrhizin tablet （control, 42 cases）. The treatment group was given oral TGPC, three times daily and 600 mg per time; the control group was given oral compound glycyrrhizin tablets, three times daily and 50 mg per time. In addition, both groups were given 10 mg of vitamin B2 and tapped the bold patches with massage. The treatment course was three months for both groups. Peripheral blood T-cell subsets （CD3^＋CD4^＋, CD3^＋CD8^＋, Th, Ts, Th/Ts） of 10 patients randomly selected from each group respectively were tested before and after three months of treatment. The effectiveness and adverse reaction of all cases were observed each month. The safety was evaluated according to the incidence rate of adverse reaction. Results： In the treatment group, the cured and markedly effective rate was 36.36% （16/44）, 50.00% （22/44） and 68.18% （30/44） at the end of first, second and third month of treatment, respectively, and the incidence rate of adverse reaction was 13.64% （6/44）. In the control group, the cured and markedly effective rate was 38.10% （16/42）, 57.14% （24/42） and 71.43% （30/42）, respectively, and the incidence rate of adverse reaction was 16.67% （7/42）. The cured and markedly effective rate and the incidence rate of adverse reaction were similar in both groups （P〉0.05）. TGPC and compound glycyrrhizin tablet can inhibit CD3^＋CD4^＋ and CD3^＋CD8^＋, and decrease the ratio of Th/Ts （P〈0.05）. Conclusion： TGPC is effective and safe in the treatment of alopecia areata.展开更多

Methods: SRs of randomized controlled trials(RCTs) on TG or TGP in treating RA were included, by searching 8 databases from their inception until December 2017. Two authors extracted data independently. We assessed the quality of SRs using AMSTAR and graded the quality of evidence according to the GRADE approach. Results: Eleven SRs containing an average of 7.6 RCTs, involving a total of 7,012 participants were included in this overview. On the basis of included SRs, TG and TGP could improve the following indexes for RA patients: American College of Rheumatology(ACR) 20 response rate, ACR50 response rate and ACR70 response rate, swollen joint count, tender joint count, erythrocyte sedimentation rate and C-reactive protein. Moreover, TGP could reduce incidence of hepatotoxicity. The most common adverse effects of TG were gastrointestinal discomfort and gonad toxicity, while for TGP was mild to moderate diarrhea. The overall quality of evidence for these findings ranged from "low" to "moderate". Conclusions: TG and TGP might be 2 potentially effective complementary and alternative drugs for patients with RA. Nevertheless, due to gonad toxicity, TG should only be considered in elderly patients or patients without reproductive needs. More evidence from high quality RCTs and SRs is warranted to support the use of TG and TGP for RA patients.展开更多

Methods RP-HPLC was developed for fingerprint analysis and determination of four ingredients in G. macrophylla roots from different sources. LC-ESI-TOF-MS was employed to identify the chromatographic peaks of the fingerprint. Results Five common peaks were identified by comparing their retention time with reference secoiridoid glucosides. Eight major peaks in chromatographic fingerprint were analyzed by on-line LC-ESI-TOF-MS. Four secoiridoid glucosides were identified based on their MS data. Conclusion The method is specific and could be served for the quality identification and comprehensive evaluation of G. macrophylla.展开更多

TGP(100, 50, 25 mg/kg) and celecoxib(2.8 mg/kg) were administered by intragastric administration for 21 d. Right hind paw swelling was assessed every 2 d. After 21 d, synovial changes of the ankle were detected by histopathology. CD4+and CD8+ T cell amounts in peripheral blood were measured by flow-cytometrically. Gene and protein levels of toll-like receptor(TLR)2, TRAF6, tumor necrosis factor ligand superfamily member 6(FASLG)in the spleen were assessed by RT-qPCR and Western Bolt, respectively. Nuclear expression of NF-κB p65 was detected by NF-κB p65 Assay Kit.RESULTS: Paw swelling and synovium lesions were obviously aggravated in AA rats. These symptoms were significantly relieved by TGP.The ratio of CD4+/CD8+ T cell was increased in AA rats, while TGP reduced this increased ratio.Gene and protein levels of splenic TLR2, TFAR6 and FASLG, and nuclear NF-κB p65 in AA rats were significantly increased, but overtly inhibited by TGP.CONCLUSION: These findings suggest that TGP’s anti-inflammatory effect onRA in rats with CFA may be related to the downregulation of TLR2/TRAF6/NF-κB pathway and the regulation of T cell subsets.展开更多
