Effect of acupoint thread-embedding on macrophage polarization of epididymis adipose tissue in obese mice / 中国针灸

OBJECTIVE@#To observe the effect of acupoint thread-embedding at "Zusanli" (ST 36) and "Fenglong" (ST 40) on the macrophage polarization of epididymis adipose tissue in obese mice, and to explore the action mechanism of acupoint thread-embedding on weight control.@*METHODS@#Among 30 male C57BL/6 mice, 10 mice were randomly selected and fed with normal diet, and the remaining 20 mice were fed with high-fat diet to establish the obesity model. Sixteen mice with successful obesity model were randomly divided into a model group and an acupoint thread-embedding group, 8 mice in each group. Eight mice were selected from mice which were fed with normal diet as the normal group. On the next day of successful modeling, acupoint thread-embedding was performed at "Zusanli" (ST 36) and "Fenglong" (ST 40) in the acupoint thread-embedding group, once every 10 days for 4 times. The body weight was recorded at 0, 8, 16, 24, 32, 40 days into intervention; the level of glucose metabolism was compared after intervention; the level of lipid metabolism and weight of epididymal adipose tissue were compared at the end of the intervention; the mRNA expression of M1 and M2 macrophage-related cytokines interleukin-10 (IL-6), monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) were detected by real-time PCR; the mRNA and protein expression of M1 macrophage labeled inducible nitric oxide synthase (iNOS) and M2 macrophage labeled arginase-1 (Arg-1) were detected by real-time PCR and Western blot.@*RESULTS@#Compared with the normal group, the body weight at 0, 8, 16, 24, 32, 40 days into intervention in the model group was increased (@*CONCLUSION@#Acupoint thread-embedding at "Zusanli" (ST 36) and "Fenglong" (ST 40) may play a role in weight control by regulating the polarization of macrophages.

The pharmacokinetic-pharmacodynamic study of novel antidiabetic drug saxagliptin in chinese schizophrenia patients complicated with T2DM / 中国药学杂志

OBJECTIVE: To investigate the pharmacokinetics and pharmacodynamics of saxagliptin tablets in Chinese schizophrenia patients complicated with T2DM. METHODS: Ten male schizophrenia patients complicated with T2DM were enrolled. The protocol was to afford multi-dose of 5 mg qd for 7 d. The blood samples were collected up to 12 h after the oral administration. The plasma concentrations of saxagliptin were determined by a validated HPLC-MS/MS method. The levels of blood glucose were also measured. The pharmacokinetic parameters were calculated by DAS 3.2.4 software. RESULTS: The main pharmacokinetic parameters of saxagliptin after multi-dose of 5 mg qd were as follows: ρmax was (16.27 ± 9.28) μg · L-1, tmax was (1.70 ± 0.48) h, t1/2 was (3.33 ± 0.59) h, AUC0-12 was (45.19 ± 18.67) μg · h · L-1, AUC0-∞ was (49.15 ± 19.71) μg · h · L-1, respectively. No significant correlation of plasma concentration and blood glucose was observed. CONCLUSION: The main pharmacokinetic parameters of saxagliptin are in the normal range among Chinese schizophrenia patients complicated with T2DM. The clinical use of the drug is generally safe, while the control of blood glucose was not effective enough for patients with great fluctuation.
