OBJECTIVE To provide a reference for optimizing and promoting the quality standards of Shechuan naolitong granules. METHODS Fifteen batches of Shechuan naolitong granules were used as samples to establish HPLC fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）. Similarity evaluation and common peak identification were performed， and orthogonal partial least squares discriminant analysis （OPLS-DA） was used to assess quality differences among different batches and to screen quality differential components. Using salvianolic acid B（SAB） as the internal reference， quantitative analysis of multi-components by single-marker （QAMS） was developed to simultaneously determine geniposidic acid （GA）， chlorogenic acid （CA）， vaccarin （VA）， ferulic acid （FA） and senkyunolide I （SI）. The results were compared with those obtained by the external standard method. RESULTS A total of 13 common peaks were identified in the HPLC fingerprints of 15 batches of samples， and the similarities of the spectra were all above 0.96. Seven chromatographic peaks were identified as GA （peak 3）， CA （peak 6）， VA （peak 8）， FA （peak 9）， SI （peak 11）， SAB（peak 12） and TA（peak 13）. OPLS-DA indicated that the differential quality markers among 15 batches were peaks 5， 11 （SI）， and 12 （SAB）.Using SAB as the internal reference， the relative correction factors for GA， CA， VA， FA and SI were calculated as 1.058 4， 0.594 3， 0.643 3， 0.342 7 and 0.262 8， respectively. The mean content of GA， CA， VA， FA， SI and SAB across the 15 batches of samples were 0.155 0， 0.085 4， 0.140 3， 0.071 8， 0.072 7， 1.276 3 mg/g， respectively， showing no significant difference compared with the ESM （P＞0.05）. CONCLUSIONS The established HPLC fingerprint and QAMS are simple， efficient and economical， providing a reference for the quality control and further development of Shechuan naolitong granules.

Aim To investigate the signaling pathways related to telmisartan-induced insulinotropic effect in rats.Methods(1)Islets and cells were isolated from Wistar rats.Islets were treated with different drugs,then supernatant liquid was collected for insulin secretion.The changes in intracellular Ca2+([Ca2+]i)concentrations of β-cells and the effects on ion channel were observed using calcium imaging tech-nology and patch-clamp technology respectively.(2)CHO-Kv2.1 cell line was constructed with lentivirus vector overexpressing Kv2.1 channel,then patch-clamp experiment was performed on CHO-Kv2.1 cells to observe the direct effect of telmisartan on Kv2.1 channel.Results Different from telmisartan,valsar-tan and irbesartan under high glucose condition did not exhibit insulinotropic effect,elevation of[Ca2+]i lev-els,and inhibition of Kv channels in[3 cells.GW9662,a peroxisome proliferator-activated receptorγ(PPARγ)blocker,did not influence the effects of telmisartan on insulin secretion,[Ca2+]i level and Kv channel.CHO cells had no endogenous outward potas-sium currents,while Kv2.1 channel current and its concentration dependent suppression by telmisartan were both detected on CHO-Kv2.1 cells.Conclusion Neither AT-1 receptors nor PPARγ is involved in telmisartan-induced insulinotropic effect,and the effect of telmisartan is partly due to the direct inhibition of kv2.1 channel.
