Rotundine (1 micromol L(-1)) was incubated with a panel of rCYP enzymes (1A2, 2C9, 2C19, 2D6 and 3A4) in vitro. The remained parent drug in incubates was quantitatively analyzed by an Agilent LC-MS. CYP2C19, 3A4 and 2D6 were identified to be the isoenzymes involved in the metabolism of rotundine. The individual contributions of CYP2C19, 3A4 and 2D6 to the rotundine metabolism were assessed using the method of total normalized rate to be 31.46%, 60.37% and 8.17%, respectively. The metabolites of rotundine in incubates were screened with ESI-MS at selected ion mode, and were further identified using MS2 spectra and precise molecular mass obtained from an Agilent LC/Q-TOF-MSMS, as well as MS(n) spectra of LC-iTrap-MS(n). The predominant metabolic pathway of rotundine in rCYP incubates was O-demethylation. A total 5 metabolites were identified including 4 isomerides of mono demethylated rotundine and one di-demethylated metabolite. The results also showed that CYP2C19, 2D6 and 3A4 mediated O-demethylation of methoxyl groups at different positions of rotundine. Furthermore, the ESI-MS cleavage patterns of rotundine and its metabolites were explored by using LC/Q-TOF-MSMS and LC/iTrap-MS(n) techniques.

Objective To evaluate the effect of awake tracheal intubation with intubating larynegeal mask airway (ILMA) on stress responses of hypertensive patients.Methods Sixty hypertensive patients,aged 45-64 yr,with body mass index of 20.3-27.5 kg/m2,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective abdominal surgery under general anesthesia,were divided into 2 groups (n=30 each) using a random number table:direct laryngoscope group (group D) and ILMA group (group I).At 3 min after topical anesthesia (T1),while epiglottis and glottis were exposed with direct laryngoscope in group D or during ILMA insertion in group I (T2),immediately after completion of intubation (T3),when the maximum change in hemodynamics after intubation appeared (at about 15 s after tracheal tubes were placed,T4),and at 5 min after completion of intubation (T5),mean arterial pressure (MAP) and heart rate (HR) were recorded,and blood samples were collected for determination of plasma epinephrine concentrations by radio-immunity method.Successful intubation at first attempt was recorded.Results Compared with the parameters at T1,the MAP,HR and plasma epinephrine concentrations were significantly increased at T2-4 in group D (P＜0.01),and no significant change was found in the parameters mentioned above at the other time point in group I (P＞0.05).Compared with group D,the MAP,HR and plasma epinephrine concentrations were significantly decreased at T2-4 (P＜0.01),and no significant change was found in the success rate of intubation at first attempt in group I (P＞0.05).Conclusion Awake tracheal intubation with ILMA does not induce strong stress responses and is helpful in avoiding the occurrence of cerebrovascular accidents,thus increasing the safty of awake tracheal intubation in hypertensive patients.

Shenfu injection is a common clinical medicine. To explore the common clinical medical combinations with Shenfu injection the real world, 25 704 patients who used Shenfu injection were selected from the hospital information system (HIS) database established by Clinical and Basic Research Institute for Traditional Chinese Medicine of China Academy of Chinese Medical Sciences. The association rules were applied in a correlation analysis on common medical combinations with Shenfu injection in the patients. According to the findings, when Shenfu injection was combined with a single medicine in clinic, the ratio of using Omeprazole, Lidocaine or Furosemide were respectively 22.19%, 20.32%, 19.61%; when Shenfu injection was combined with two medicines, the top three medical combinations were respectively midazolam + omeprazole (11.01%), lidocaine + omeprazole (10.8%) and propofol + midazolam (10.76%); when Shenfu injection was combined with three medicines, the top three medical combinations were respectively propofol + fentany + midazolam (8.83%), remifentanil + propofol + midazolam (8.77% ) and propofol + midazolam + omeprazole (8.77%). According to the further analysis, the combination of Shenfu injection and Propofol + Fentany + Midazolam may reduce the incidence of hypotension and bradycardia during anesthesia, accelerate recovery after anesthesia and relieve the synergistic effect after anesthesia. The combination of Shenfu injection and furosemide may show the synergistic effect in treating the acute left ventricular failure by reducing the returned blood volume and increasing the myocardial contractile force and vitality. The combination of Shenfu injection and Omeprazole may play the synergistic effect in shortening the digestive tract ulcer healing time, reducing the ulcer recurrence and preventing hemorrhagic shock and stress ulcer caused by shock in treating ulcer hemorrhage.

The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition patients, and it was more combined with dehydration medicine by critically admission condition patients. This research found that the dynamic characteristics for the combination of Chinese patent medicine and western medicine of acute phase of ischemic stroke patients by big data analytics and complex networks modeling, and provide basis for acute phase of ischemic stroke patients, it provide basis for ischemic stroke treatment strategy making.

To assess whether the Shuxuening injection influences liver function, this paper analyzes the hospital information system (HIS) data from 20 national hospitals. The patients were divided two groups: patients (5 353 cases) using Shuxuening injection acted as the exposed group, then the patients (4 863 cases) not using Shuxuening injection acted as the unexposed group. Take the abnormal changes of alanine aminotransferase and aspartate aminotransferase indexes as the result. Control confounding factors by stratification analysis, classic logistic regression analysis, before logistic regression based on propensity score weighting method and logistic regression based on generalized boosted models (GBM) of propensity score weighted combination of covariate adjustment. Then, the study analyzes the effects of Shuxuening injection on liver function by observing the changes of the indexes. Analysis of the impact of parenterally administered Shuxuening on ALT shows that, before logistic regression based on propensity score, then the regression is -0.232 (P value is 0.017). However, after logistic regression based on propensity score method the regression became -0.150 (P value is 0.370). Whereas, analysis of the impact of parenterally administered Shuxuening on AST shows that, before logistic regression based on propensity score, then the regression is -0.034 (P value is 0.767). However, after logistic regression based on propensity score method the regression became -0.091(P value is 0.538). Thus, propensity score method can control a large number of confounding factors, making the results more close to the clinic. Hence, based on existing electronic medical data, this study didn't find that parenterally administered Shuexuening influences ALT and AST.

The safety of drugs has been the important issue that has caught the mutual attention of clinicians and patients. Kidney is one of the important organs in drug metabolism. The study is based on hospital information system (HIS) data from 20 nationwide general hospitals, indicated by Scr and BUN. Generalized boosted models (GBM) based on propensity score method were used to balance confounding factors. The study contrasts changes on renal function between used Shuxuening injection patients and the unused to explore whether Shuxuening injection affects renal function in clinical. The results showed that Shuxuening injection is likely to affect Scr in logistic regression (P value is 0.035); after the logistic regression based on propensity score method (P value became 0.513, 0.590), no differences were found between the two groups; before and after the logistic regression based on propensity score method (P value was less than 0.05), Shuxuening injection possibly affects BUN. Nevertheless, this study is a retrospective analysis. Logistic regression based on propensity score method can control the known confounding factors very well, while there may be the unknown ones. Therefore, the further exploration is required to monitor whether Shuxuening injection affects really BUN, which will provide clinical guidance for Shuxuening injection safe application.
