Rhynchophylla is a Chinese herb commonly used in clinical practice. It's also the primary herb of some famous Chinese herbal compound such as Tianma Gouteng decoction, and Lingyang Gouteng decoction. According the record from many previous materia medica literatures, rhynchophylla should be added later during decoction. Pharmaceutical research showed that rhynchophylla alkaloids were not stable. Which has resulted in many problems in the research and its application. For example, there was not a quantitative determination method in "Chinese Pharmacopoeia" of past and present versions, which seriously impacted its quality control and product application. Firstly, records from previous materia medica literatures and "Chinese Pharmacopoeia" were systematically sorted based on the chemical stability of rhynchophylla. Secondly, pharmaceutical research including chemical compositions and their stability, pharmacological effects, extraction process and quality analysis, was reviewed after reference of literatures published at home and abroad in recent decades. Positive reference and evidence for further research and development of rhynchophylla will be provided in the article.

OBJECTIVE:
To eludicate the risk factors of mechanical ventilation and prolonged mechanical ventilation in patients with severe multiple injuries.
METHODS:
Consecutive patients with severe multiple injures who were treated in Peking University People's Hospital Trauma Medical Center between December 2016 and December 2019 were enrolled in this restropective chart-review study. According to mechanical ventilation and ventilatory time, the patients were divided into mechanical ventilation (MV) group and non-mechanical ventilation (NMV) groups, prolonged mechanical ventilation (PMV) group and shortened mechanical ventilation (SMV) groups. Clinical data such as gender, age, base excess, mechanism of injury, Glasgow Coma Scale (GCS), abbreviated injury scale (AIS) and injury severity score (ISS) were collected. To indentify the risk factors of mechanical ventilation and prolonged mecha-nical ventilation, univariate and multivariate Logistic analyses were carried out.
RESULTS:
In the present study, 112 patients (82 male, 30 female) with severe multiple injuries having a median age of 52 (range: 16-89 years) and a median ISS of 34 (range: 16-66) were enrolled. The primary mechanism of injury was traffic accident injury and falling injury. In the study, 62 and 50 patients were assigned to MV and NMV groups, respectively. Logistic analysis showed that GCS (OR=0.72, 95%CI: 0.53-0.92, P=0.03), base excess (OR=0.56, 95%CI: 0.37-0.88, P=0.002) and multiple rib fracture (OR=1.72, 95%CI: 1.60-2.80, P=0.012) were independent significant risk factors for mechanical ventilation after severe multiple injuries. Within the mechanical ventilation group, 38 and 24 patients were assigned to PMV and SMVgroups, respectively. Compared with the SMV group, the PMV group had a higher ISS and higher rate of severe head trauma. The length of hospital stay of PMV group was longer than that of SMV groups. Meanwhile, the incidence of tracheotomy in PMV group was high.
CONCLUSIONS
GCS, base excess and rib fracture might be independent risk factors for mechanical ventilation. Higher ISS and lower GCS might prolong the ventilatory time and the length of hospital stay. Meanwhile, the incidence of tracheotomy was high in PMV group because of the longer ventilatory time and poor consciousness.

Objective To explore the effect of evidence-based nursing during preoperative interview for abdominal surgery patients' recovery after general anesthesia. Methods 124 patients who accepted selective operation on abdominal region were randomly divided into evidence-based group and control group, 62 cases ineach group. On the base of routine method in the preoperative interview, the evidence-based group established evidence-based information supporting system, which aimed to dredge the psychological stress of the patients'response to surgery individually and intervene by demonstrating simulation of operation process. According to the traditional way, control group accepted routine preoperative interview. To compare patients' indexes of two groups before and after anesthesia. Results Patients' heart rate and the mean arterial pressure lower than control group before anesthesia in evidence-based group. The dosage of midazolam in evidence-based group was less than the control group (t =6. 73,7. 24,8. 17;P <0. 05). The difference of pre-anesthesia anxiety scores was statistically significant between evidence-based group and control group (t =7. 68 ,P <0. 01 ). But the difference of the anxiety scores after operation wasn' t statistically significant between two groups ( t = 0. 62, P > 0. 05 ). Patients in evidence-based group took shorter revival time than control group ( t = 9. 71,10. 45,11.32 ; P < 0. 01 ). Compared the different period pain score of two groups, patients of evidence-based group were lower than those of the control group, and the patients' satisfaction scores also were higher than those of control group, the differences were statistically significant (t =2. 38,5. 22,2. 63,7. 62;P <0. 05). Conclusions Application evidence-based nursing information support in preoperative interview effectively relieves the preoperative anxiety, can reduce the dosage of narcotic and sedative drugs, shorten the revival time, improve patient' s satisfaction and have reached the antieipant effects.

To develop a sensitive and specific high performance liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) method for the determination of mosapride in human plasma, mosapride and internal standard tamsulosin were extracted from plasma with liquid-liquid extraction, then separated on a Waters ACQUITY UPLC BEH C18 column (50 mm x 2.1 mm, 1.7 microm ID) with gradient elution at flow-rate of 0.25 mL x min(-1). The mobile phase was water (containing 0.3% formic acid) and acetonitrile under gradient conditions. Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 422 --> m/z 198 and m/z 409 --> m/z 228 were used to quantify mosapride and the internal standard, respectively. The linear calibration curve was obtained in the concentration range of 0.17 - 68.00 ng x mL(-1). The lower limit of quantification was 0.17 ng x mL(-1). The inter- and intra-day precision (RSD) was less than 13%, and the accuracy (RE) was within +/- 6.3% calculated from QC samples. The method was used to determine the concentration of mosapride in plasma after a single oral dose of 5 mg mosapride citrate to 20 healthy male Chinese volunteers. The method has been proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of mosapride.

OBJECTIVETo investigate the roles of signal transduction and activator of transcription 6 (STAT6) and orosomucoid 1-like 3 (ORMDL3) in airway remodeling among asthmatic mice and to observe the effects of budesonide (BUD) on their expression.
METHODSThirty BALB/c mice were randomly divided into control, asthma, and BUD intervention group. The mice were sensitized and challenged with ovalbumin (OVA) to establish a mouse model of asthma. The BUD intervention group received aerosol inhalation of BUD dissolved in normal saline 30 minutes before each OVA challenge, while normal saline was used instead of OVA solution in the control group. The pathological changes in the airway were observed by hematoxylin-eosin staining and Masson staining. The interleukin-13 (IL-13) level in lung homogenate was measured by enzyme-linked immunosorbent assay. The mRNA expression of STAT6 and ORMDL3 was measured by RT-PCR.
RESULTSThe asthma group showed more pathological changes in the airway than the control and BUD intervention groups, and the BUD intervention group had reduced pathological changes in the airway compared with the asthma group. The asthma and BUD intervention groups had significantly higher IL-13 levels and mRNA expression of STAT6 and ORMDL3 than the control group (P<0.05), and these indices were significantly higher in the asthma group than in the BUD intervention group (P<0.05). The Pearson correlation analysis showed that STAT6 mRNA expression was positively correlated with ORMDL3 mRNA expression (r=0.676, P=0.032).
CONCLUSIONSSTAT6 and ORMDL3 may be involved in the airway remodeling of mice, and BUD can reduce airway remodeling in asthmatic mice, possibly by down-regulating mRNA expression of STAT6 and ORMDL3.
