On the basis of the qualitative preparation quality markers of Zhibao Sanbian Wan (ZBSBW), we screened out the quantitative markers and evaluated the content consistency of ZBSBW. A method capable of simultaneously determining 34 compounds in ZBSBW was established based on HPLC-MS/MS, and 16 batches of ZBSBW were simultaneously analyzed by this method. Furthermore, we explored a general strategy for analyzing the component migration in preparation, plasma, brain tissue and cerebrospinal fluid. The methodological investigation was confirmed by linear range, recovery (85.10%-105.07%), precision (RSD: 1.37%-4.58%), stability, and repeatability (3.00%-12.45%), the established method was suitable for the detection and quantification of the compounds in ZBSBW. The contents of compounds in ZBSBW were all lower than 1 mg·g-1, and the contents and daily dose of nystose were the highest, followed by echinacoside, paeoniflorin, osthole and paeonol. The results of systematic clustering showed that the contents were consistent for ordinary preparations of ZBSBW. The principal component analysis showed that the components of berberine, ginsenoside Re, ginsenoside Rg1, pinoresinol diglucoside and tenuifolin had large variation, which contributed significantly to the grouping. The contents of echinacoside, verbascoside, polygalaxanthone Ⅲ,

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

ObjectiveTo study the in vitro kinetics of Jiaojiang cataplasms and evaluate its pharmacodynamics, so as to provide a feasible basis for the development of this preparation. MethodThe improved Franz diffusion cell was used for the in vitro release in semipermeable membrane and transdermal absorption in in vitro mouse skins. The contents of hydroxy-α-sanshool, 6-gingerol, ginsenoside Rb1 were determined by high performance liquid chromatography (HPLC), to evaluate the in vitro release and transdermal absorption of Jiaojiang cataplasms. The mobile phase of 6-gingerol and hydroxy-α-sanshool was water-acetonitrile-methanol (2∶1∶1) with the detection wavelength of 280 nm. The mobile phase of ginsenoside Rb1 was acetonitrile-0.1% phosphoric acid aqueous solution (31∶69) with the detection wavelength of 203 nm. A mouse intestinal paralysis model was established, and mice were randomly divided into five groups, namely sham operation group, model group, domperidone group (3.9 mg·kg-1) and high- and low-dose groups of Jiaojiang cataplasms (6.2, 3.1 g·kg-1, measured by crude drug dosage), to observe the effect of this preparation on gastrointestinal propulsion function. ResultAverage release rates of hydroxy-α-sanshool, 6-gingerol and ginsenoside Rb1 at 24 h were 16.41, 4.23, 4.15 μg∙cm-2∙h-1, the average transdermal rates of them at 24 h were 2.31, 0.64, 0.29 μg∙cm-2∙h-1, their skin retention values were 19.56, 3.59, 1.61 μg, respectively. According to the Ritger-Peppas equation, the release of hydroxy-α-sanshool, 6-gingerol, ginsenoside Rb1 was non-Fick diffusion. The high-dose group of Jiaojiang cataplasms could improve intestinal function of model mice after small intestinal friction injury, and promote intestinal peristalsis and small intestinal propulsion rate (P<0.05). ConclusionJiaojiang cataplasms has in vitro release and transdermal properties, the in vitro release conforms to Higuchi equation, and transdermal absorption behavior conforms to zero-order kinetic equation, which can improve the postoperative function of the small intestine and the propulsion function of small intestine. It preliminarily indicates that the preparation has certain clinical development value.
