ABSTRACT
Objective:To investigate the effect of constant temperature blankets on intravascular hypothermia for severe traumatic brain injury (sTBI). Methods:A total of 112 inpatients with sTBI from January, 2013 to December, 2018 were reviewed. They were divided into control group (n = 58) and observation group (n = 54) according to whether a self-warming blanket was used. They were assessed with Bedside Shivering Assessment Scale (BSAS). Their dosages of anti-shivering medicine, coagulation and intracranial pressure were recorded. The scores of Glasgow Outcome Scale Extended (GOSE) and the mortality one, six and twelve months after discharge were observed. Results:The incidence and severity were less in the observation group than in the control group (χ2 = 16.212, P < 0.01). The dosage of anti-shivering medicine was less in the observation group than in the control group (t > 1.269, P < 0.05). The hypercoagulation relieved significantly six hours after hypothermia in the observation group, and it was stable twelve hours after hypothermia. For the control group, the hypercoagulation relieved significantly twelve hours after hypothermia, and it was stable 24 hours after hypothermia. The intracranial pressure decreased more in the observation group than in the control group. The GOSE score and the mortality were less in the observation group than in the control group (t > 1.168, P < 0.05) one, six and twelve months after discharge. Conclusion:Application of self-warming blankets in intravascular hypothermia for sTBI may relieve shivering, hypercoagulation and intracranial pressure, to improve the outcome of patients.
ABSTRACT
Objective To investigate the effect of early cognitive rehabilitation training on cognitive function of patients after carotid endarterectomy. Methods The clinical data of 32 patients with carotid stenosis undergoing carotid endarterectomy ( CEA) admitted to the neurosurgery department of Chongqing emergency medical center from January 2016 to June 2018 were retrospectively analyzed.Sixteen pa-tients with conventional CEA admitted from January 2016 to June 2017 were treated as the control group.Sixteen patients with early cognitive rehabilitation training admitted from July 2017 to June 2018 were treated as cognitive on the basis of routine treatment after CEA.In the train-ing group,the Montréal Cognitive Assessment Scale (MoCA) scores at 1 week and 3 months after surgery were analyzed. Results There was no significant difference in MoCA score between the two groups (P>0.05) at 1 week after surgery compared with those before surgery. The MoCA scores of the two groups were significantly higher than those before the operation 3 months after surgery(P<0.05).The change of the cognitive training group was more significant than that of the control group(P<0.05). Conclusion After carotid endarterectomy,early cognitive rehabilitation training can help reduce the incidence of postoperative cognitive dysfunction and improve cognitive function.
ABSTRACT
Coding rules for Chinese medicines and their codes (GB/T 31774-2015) was issued by General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) and Standardization Administration of the People's Republic of China (SAC) in 2015. Coding system for Chinese medicines (ISO 18668-1, 2, 3 and 4) series were issued one after another by International Organization for Standardization in 2016 and 2017. In this paper, the comparative study on the GB/T 31774 and ISO 18668-1, 2, 3 to 4 would be conducted to expound the similarities and differences among them. This essay aims at promoting the application of national and international standards of coding system in production and operation enterprises and the medical institutions of traditional Chinese medicine (TCM), reducing their repetitive investment to meet the Chinese medicine import and export trade requirement in future. Moreover, it provides the cornerstone and support for TCM standardization, and makes Chinese medicines standard gain dominance in field of international TCM standards, occupying the high ground of international market in the traditional medicine field of the world. It may promote the "Internet + TCM service" in our country, and let the Chinese medicine industry go out of the country and into the world to contribute to human health.
ABSTRACT
Neobavaisoflavone is one of flavonoids of traditional Chinese medicine Psoralea corylifolial. It has numerous biological properties such as antibacterial, anti-inflammatory, anti-cancer, and anti-osteoporosis effects. This paper aimed to investigate the absorption mechanism of neobavaisoflavone in Caco-2 cell monolayer model. The analyte and osalmide were separated on Thermo Syncronis C18 column with methanol-0.1% formic acid solution (90∶10) as the mobile phase, at a flow rate of 0.2 mL•min⁻¹. The concentration of neobavaisoflavone was determined in eletrospray ionization(ESI) positive ion mode with osalmide as an the internal standard. The effects of time, concentration, P-gp inhibitor verapamil, MRP-2 inhibitor MK-571 and BCRP inhibitor Ko143 on the absorption of neobavaisoflavone were investigated. According to the results, neobavaisoflavone showed a good linearity within the concentration of 10-2 000 μg•L⁻¹, and the results of its specificity, matrix effect, extraction recovery, precision, accuracy and stability all met the requirements. In the Caco-2 cell monolayer model, the transport volume of neobavaisoflavone was correlated positively with the time and concentration. The ER values of 15, 30, 50 μmol•L⁻¹ neobavaisoflavone were 1.64, 1.94,0.99, respectively. As compared with the control group, all of verapamil hyduochloride, MK-571 and Ko143 could promote the transportation of neobavaisoflavone, and the effect was more obvious in verapamil hyduochloride and Ko143. The absorption of neobavaisoflavone may be mainly of active transport in Caco-2 cell monolayer model, and also involve passive transport. Excretion mechanism of intestinal transport protein may be also involved.
ABSTRACT
<p><b>OBJECTIVE</b>An accurate and reliable analytical method for-simultaneous determination of six active components (scopolin, chlorogenic acid, scopoletin, isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C) in plants of Erycibe was developed.</p><p><b>METHOD</b>Scopolin, chlorogenic acid, scopoletin, isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C in the samples were well separated in analytical HPLC by gradual elution with methanol-0.1% formic acid solution.

<p><b>OBJECTIVE</b>To investigate the role of high-frequency ultrasound (HFUS) in evaluating in the effectiveness of conservative treatment for professional athletes with patellar tendon enthesiopathy.</p><p><b>METHODS</b>According to different treatment intensities, 24 professional athletes with patellar tendon enthesiopathy were randomly divided into painless group, slightly-painful group and extremely-painful group. Then changes of the HFUS findings [including ranges of two-dimensional diseases and blood conditions by Color Doppler Flow Imaging (CDFI)] of patellar tendon before and after the treatment were recorded. The results were also compared with conventional clinical treatment evaluations.</p><p><b>RESULTS</b>After two courses of treatment,the percentage of athletes whose pain was resolved or disappeared was 37.5% in painless group, 87.5% in slightly-painful group, and 62.5% in extremely-painful group. The pain score was 4.50 ± 2.07, 4.88 ± 1.13, and 6.13 ± 1.55 in painless group,slightly-painful group,and extremely-painful group, respectively,before treatment and 4.88 ± 2.17, 3.00 ± 1.77,and 5.13 ± 2.36 after treatment. The average pain score remarkably decreased in the slightly-painful group and extremely-painful group,and such difference was statistically significant in the slightly-pain group (P<0.05). The effective rate (defined as thinner patellar,decreased hypoecho area and fewer blood distribution in the lesion) was 38%, 50%, and 62% in the painless group, slightly-painful group,and extremely-painful group, and the rates in the slightly-painful group and extremely-painful group were significantly higher than that in painless group (both P<0.05).</p><p><b>CONCLUSIONS</b>HFUS can display the ultrasonographic changes of patellar tendon enthesiopathy after conservative treatments in an objective and quantitative manner. Compared with conventional clinical evaluations, it can more accurately reflect the disease recovery status.</p>
