RESUMO
Epilepsy is a long-term, chronic, recurrent, multi-factorial, multi-symptomatic nervous system disease, and was caused by abnormal discharge of brain neurons. Etiology can cause irreversible brain dysfunction and even death. There are about 6.5 million children with epilepsy in China, with incidence rate twice that of adult, presenting serious threaten to children's growth and development. Vitamin D has been well-known for crucial importance to development of nervous, skeletal, and immune system. Studies have found that pediatric epilepsy as well as other neurological diseases were closely related with vitamin D deficiency. First, a large number of studies have shown that vitamin D in children with epilepsy is affected by epilepsy itself; second, the use of anti-seizure medicines can alter metabolism of vitamin D by inducing cytochrome oxidases; third, the inducement was concerned to varieties, combination and duration of anti-seizure medicines; fourth, it was expected that supplement of vitamin D during antiepileptic treatment would guarantee an improvement of treating given that anti-seizure medicines may lead to deficiency of vitamin D. Large numbers of researches have reported on the correlation ship between pediatric epilepsy and vitamin D. However, there is still a lack of systematic review. This article aims to retrospect the research progress of relationship between pediatric epilepsy and vitamin D, and provide valuable feedbacks on further treatment of pediatric epilepsy.
RESUMO
In recent years, monoclonal antibodies (mAbs) have been developing rapidly and widely used in fields of tumor, immunity, blood and other systemic diseases. Global share of mAbs in prescription drug market had reached up to $ 140 billion, 15.3% by 2019. As macromolecule proteins, with special structures and physiological properties, mAbs have great differences in absorption, distribution, metabolism and excretion in vivo compared with small molecule drugs, including characteristics of relatively large molecular mass, high specificity and selectivity in target combination, non-linear pharmacokinetics, time dependence, long half-life and so on. Fully understanding of these special pharmacokinetic characteristics shall effectively guide analysis of mAbs. Meanwhile, the particularity and complexity of disposal mechanism in organisms greatly increase the difficulty of biological detection. As a result, it is necessary to establish exclusive, sensitive, accurate and repeatable quantification methods in biological samples. This article focuses on pharmacokinetic characteristics, main analytical methods, and methodology validation of quantification for mAbs in biological samples, expounding with comparisons of small molecular drugs, so as to prompt development of pharmacokinetic study of this kind of drugs.
RESUMO
OBJECTIVE： To systematically evaluate the efficacy and safety of Endostar combined with gemcitabine and cisplatin in the treatment of non-small cell lung cancer （NSCLC）， and to provide evidence-based reference for clinical drug use. METHODS： Retrieved from Cochrane Library， PubMed， Embase， ClinicalTrials， CNKI， Wanfang and VIP database， randomized controlled trials （RCT） about Endostar combined with gemcitabine and cisplatin（trial group） vs. gemcitabine combined with cisplatin （control group） for NSCLC were collected. After literature screening， data extraction and quality evaluation with Cochrane 5.1.0 bias risk evaluation tool and Jadad scale， Meta-analysis was performed by using Rev Man 5.3 software. RESULTS： A total of 27 RCTs were included， involving 1 646 patients. Results of Meta-analysis showed that response rate [RR＝1.67， 95％CI（1.48，1.89），P＜0.000 01] and clinical benefit rate [RR＝1.26， 95％CI （1.20， 1.33），P＜0.000 01] of trial group were significantly higher than those of control group. There was no statistical significance in the incidence of leucopenia [RR＝0.98，95％CI（0.88， 1.11），P＝0.79]， thrombocytopenia [RR＝1.07， 95％CI（0.91， 1.26），P＝0.39] and gastrointestinal reaction [RR＝1.01， 95％CI（0.90， 1.14），P＝0.85] between 2 groups. CONCLUSIONS： Endostar combined with gemcitabine and cisplatin can improve therapeutic efficacy of NSCLC patients， without increasing the incidence of ADR.
RESUMO
A simple,rapid and sensitive liquid chromatography-mass spectrometry（LC-MS）method was developed for the determination of salidroside in rat plasma and study of its pharmacokinetics after oral administration of suspension of Erzhi Wan and Fructus Ligustri lucidi into Wistar rats.Plasma sample of 200 μL was extracted with acetic ether-isopropanol（2∶1）and the extraction was performed on a Kromasil C18 column（150 mm×4.6 mm,5 μm）with the mobile phase of methanol-water（41∶59,v/v）within a run time of 6.0 min.The analyte was monitored with positive electrospray ionization（ESI）by selected ion monitoring（SIM）mode.The target ions were m/z 323.05 for salidroside and m/z 411.05 for internal standard（IS）geniposide.A good linear relationship was obtained over the range of 5.0-500.0 ng/mL and the lower limit of quantification was 5.0 ng/mL.The validated method was successfully applied to the pharmacokinetic study of salidroside in rat plasma after oral administration of suspension of Erzhi Wan and Fructus Ligustri lucidi.

RESUMO
Objective To explore the influence of health education on patients with dysphgia and related complications.Methods Different methods of health education were used with 87 patients with different dysphagia conditions and their earegivers.The health education was oriented to dysphgia evaluation and appropriate functional training to improve deglutition.The severity of dysphgia and related complications were observed before and after the health education. Results Health education combined with functional training could reduce the possibility of pul-monary infection,misaspiration and malnutrition for post-stroke dysphagic patients,and the difference was statistical-ly significant. Conclusions Health educmion combined with functional training is effective in reducing the possi-bility of pulmonary infection and malnutrition and preventing misaspiration in stroke patients with dysphgia.It can help such patients regain the independent deglutition ability in the short term.
