There are few articles or reports collecting evidence about parenterally administered salvianolate from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about parenterally administered salvianolate. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data) and literature analysis. All the four aspects build an evidence body for Kudiezi Solution in order to inform its safety use in clinical practice and further study.

OBJECTIVETo observe the effects of Dachengqi Granule (DCG) in the recovery of gastrointestinal function and the condition of patients in the perioperative period of total laparoscopic hysterectomy.
METHODSTwo hundred and one patients received total laparoscopic hysterectomy were assigned to 2 groups, the treated group (103 cases) was orally administered DCG twice, 9 g at 4:00 pm, one day before operation and 6 g at 16 h after operation, while to the control group, enema with 400 mL of soap solution at 8:00 pm one day before operation and acupoint ST 36 injection with 1 mL neostigmine at 16 h after operation were given.
RESULTSTotal laparoscopic hysterectomy was accomplished successfully in all patients, no need to receive open abdominal operation, and with no post-operational complications. In the treated group, the operation time was (116.8 +/- 29.7) min, the operative blood loss was (141.6 +/- 25.1) mL, the post-operative temperature was (37.38 +/- 1.39) degrees C, while those in the control group were (119.6 +/- 28.4) min, (150.6 +/- 22.1) mL, and (37.55 +/- 0.43) degrees C, correspondingly, showing insignificant difference between the two groups (P > 0.05). The white blood cell count on the 1st day after operation was (11.18 +/- 2.93) x 10(9)/L in the treated group, and (12.57 +/- 3.55) x 10(9)/L in the control group (P < 0.01); time for post-operative aerofluxus in them was (35.66 +/- 5.72) h, and (41.77 +/- 6.06) h; time for post-operative defecation (48.47 +/- 18.97) h, and (54.81 +/- 21.30) h, respectively, all showed statistical difference between the two groups (P < 0.01 or P < 0.05).
CONCLUSIONAdministering DCG before and early after operation can effect better than pre-operational enema in ensuring the gynecological operation progression smoothly, and it could also promote the recovery of post-operational gastrointestinal function and improve patients' condition in the perioperative period.

This project is to study the metabolites of Laportea bulbifera extract in rat feces. After the SD rats were gavaged with the extract(136 g·kg~(-1), according to the crude drug dose), the metabolites in their feces were detected by UHPLC-Q-TOF-MS~E technique, and the obtained mass spectrometry data was combined with UNIFI software for prediction. The prototype components and metabolites in rat feces were identified with reference materials and related literature. A total of 43 metabolites were identified(including 8 prototype components and 35 metabolites). The metabolic pathways mainly include monocaffeoylquinic acid(hydrogenation reduction, ring-opening cracking, sulfation, hydroxylation, glucuronidation), quercetin(O-C2 bond ring-opening cleavage, C2-C3 double bond reduction, rutin carbonylation) and so on. The metabolites and metabolic process of L. bulbifera extract in rat feces were clarified, which provided a basis for the study of the active substances and its mechanism of action.

Previous studies on the genus Clusia have shown anti-inflammatory and antiproliferative effects of the leaf extracts, but its antinociceptive activity has never been characterized. In the present study, the antinociceptive activity of the hexane extract of the leaves of Clusia nemorosa G. Mey, called HECn, was examined. Antinociceptive activity was evaluated using acetic acid-induced writhing, formalin, and hot-plate tests. All experiments were carried out on male Swiss mice. The extract (1-400 mg·kg(-1)), given by intraperitoneal route (i.p.) 1 h prior to testing, produced a dose-dependent inhibition on the number of abdominal writhings, with an ID50 of 62 mg·kg(-1). In addition, HECn was able to prevent the visceral pain induced by acetic acid in mice for at least 2 h. In the formalin test, HECn had no effect in the first phase, but produced an analgesic effect on the second phase with the inhibition of licking time. The HECn did not show a significant analgesic effect in the hot plate test. Pretreatment with yohimbine attenuated the antinociceptive effect induced by HECn in the writhing test. However, naloxone, atropine, or haloperidol did not affect antinociception induced by HECn in the writhing test. Together, these results indicate that the extract from the leaves of Clusia nemorosa produces antinociception in models of chemical pain through mechanisms that suggest participation of the adrenergic systems pathway.

Reperfusion is the most effective treatment for acute myocardial infarction, markedly reducing mortality and morbidity. Reperfusion however induces necrotic and apoptotic damages to cardiomyocytes, that were viable prior to reperfusion, a process called myocardial ischemia/reperfusion injury(MI/RI). Over the past 30 years, hundreds of experimental interventions (both pharmacologic and nonpharmacologic) have been reported to protect the ischemic myocardium in experimental animals; however, with the exception of early reperfusion, none has been translated into clinical practice. The population-based survey assessed men have about twice the total incidence of morbidity and mortality of women, and the sex gap in morbidity tends to diminish after age 45 years. So hormone replacement therapy (HRT) is given to treat the MI/RI, and lots of studies shows that the side effect is greater for estrogen, compared with phyestrogen. In this article, we review the important pathogenesis of myocardial ischemia reperfusion injury, the prevention and limitations of HRT. And we highlight the mechanism of phyestrogens treatment the MI/RI in experiment. The aim is to provide the theoretically new way of develop the safe and effective products for the researchers.
