Objective To compare the contents of main compounds and the composition of volatile oil from the new hybrid of Amomum villosum Lour. Spring No.1-F4 with those in its female parent Longfruit No.2. Methods Steam distillation, gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) methods were used for analyzing the content differences of main compounds and compositions of volatile oil between Spring No.1-F4 and Longfruit No.2. Results The contents of volatile oil and bornyl acetate from Spring No.1-F4 and Longfruit No.2 met the standard required by Chinese Pharmacopoeia. The content of volatile oil from Spring No.1-F4 was higher than that of Longfruit No.2, and there were some differences between the two in the composition of volatile oil and their relative contents. Conclusion The effective constituents in Spring No.1-F4, a new hybrid species of Amomum villosum, has reached the standard required by Chinese Pharmacopoeia, which is expected for solving the problems of difficulty in pollination and for improving the yield and quality of Amomum villosum.

Comorbid depression and chronic pain are highly prevalent in individuals suffering from physical illness .Here, we critically examine that inflammation is the possible mechanism of comorbidity of pain and depression .These mechanisms include direct effects of cytokines on the neuronal environment or indirect effects via downregulation of G protein -coupled receptor kinase 2, activation of the tryptophan-degrading enzyme indoleamine 2,3-dioxygenase that generates toxic kynurenine metabolites .We review the role of in-flammation in the mechanism of the commorbidity of depression and pain .

Objective To determine ED50 and ED9 5 of etomidate for combined remifentanil used in elderly patients in gastroscope.Methods Twenty-three patients were scheduled to receive gastros-copy aged 65-78 years old including males 13 and females 10,weighting 45-76 kg and ASA Ⅰ-Ⅲ. They were slowly injected remifentanil 0.3 μg/kg,and then etomidate 0.20 mg/kg,gastroscopy was performed after their eyelash reflex disappeared.The dosage of etomidate were determined by modified up-and-down methods,0.20 mg/kg was initial dosage.During the gastroscope,restlessness, frowning,swallowing,choking cough could be seen.The adjacent experimental interval dosage was 0.05 mg/kg,the trial was ended when there was the seventh cross-sectional,and determined the ED50 and ED9 5 of etomidate and (95%confidence interval)of them for gastroscope with probability a-nalysis methods.Results The ED50 of etomidate was 0.1 7 mg/kg and 95%CI 0.14-0.21 mg/kg,and the ED9 5 was 0.23 mg/kg,95%CI 0.20-0.42 mg/kg respectively.Conclusion The ED50 and ED9 5 of etomidate combined with remifentanil used for elderly patients for gastroscope respectively are 0.1 7 mg/kg and 0.23 mg/kg.

Objective:To compare the effects of repetitive transcranial magnetic stimulation (TMS) at three different relatively high frequencies on neuropathic pain so as to find the best frequency.Methods:One hundred Sprague-Dawley rats were randomly divided into a sham operation group, a model group, a TMS group and a control stimulation group. The TMS group was further divided into a 5Hz group, a 10Hz group, and a 20Hz group. The rats in the model, control stimulation and TMS groups received constriction injury of the sciatic nerve, while the rats in the sham group were given a sham version of the operation. On the third day after the operation the rats in the TMS group and the control stimulation group began to receive TMS treatment. Neuropatic pain was evaluated on the day before the operation, and on the 3rd, 5th, 7th, 10th and 12th days after the operation. The evaluations included the paw withdrawal thermal latency (PWTL) and the paw withdrawal mechanical threshold (PWMT).Results:The average PWTLs and PWMTs in all of the TMS groups increased with the TMS treatment. Those of the 10Hz and 20Hz groups were significantly higher than the 5Hz group′s average, while there were no significant differences between the 10Hz group and 20Hz group.Conclusions:High-frequency TMS at different frequencies has different effects on neuropathic pain, at least in rats. The treatment efficacy at 10 and 20Hz is superior to that at 5Hz.

OBJECTIVE:To provide reference for strengthening the management of drug off-label dosage in hospital. METH-ODS:PDCA cycle management was conducted to investigate the current situation of off-label dosage of Alprostadil injection (Li-po-PGE1)in endocrinology department of our hospital before Jul. 2012 in the Plan stage,identify problems,find reasons and devel-op intervention objectives and measures;after intervention in Do stage,medical advices were checked periodically in Check stage, and the data in the same stage of 2013 were spot-checked in Astage stage,intervention effect was analyzed and interventional pro-cess was standardized. RESULTS:Totally 943 medical advices,including 126 cases/times were analyzed before PDCA intervention and according to the data of cases,medical advices and drug usage amount,the incidences of off-label dosage were 39.68%, 31.50% and 47.90%,respectively;after a cycle of PDCA intervention,totally 414 medical advices,including 73 cases were ana-lyzed and the incidences of off-label dosage were 0. The prescribed daily dose(PDD)was decreased from 13.15 μg to the predeter-mined range(10.00 μg)with decrease rate of 23.95%;the drug use density(DUD)was decreased from 59.82 to 20.07 with de-crease rate of 66.45%. There were significant differences in among the incidence of off-label dosage,PDD and DUD of Lipo-PGE1 (P<0.05). It reached the expected targets. CONCLUSIONS:Because of its well-organized ideas on work and continuous improve-ment methods of circulation,PDCA cycle management provides a workable avenue to manage drug off-label dosage uses in hospital.

Objective To evaluate of the glucose screening retest for gestational diabetes mellitus (GDM) during pregnancy. Methods A retrospective analysis of 714 pregnant women screened for GDM, between December 1,2001, and December 31,2002, was performed.The first glucose challenge test(GCT) was performed in 16～27 week and retested in 28～38 week.Diagnosis of GDM was based on the criteria of Dong.NDDG criteria was also discussed. Results (1) 1-hour glucose value of 50 g GCT ≥7.8 mmol/L was set as abnormal.The first 50 g GCT abnormal rate was 26.6%(190/714),and the retest abnormal rate was 35.2%(225/639).The mean age of pregnant women in 50 g GCT positive group was significantly higher than that in the negative group( P

Objective 4-Hydroxyisoleucine (4-HIL) is the active component isolated from the seeds of Trigonella foenum-graecum. It exerts broad pharmacological effects such as anti-hyperglycemia,blood lipid lowing,improvement of insulin resistance,etc. As the Chinese traditional medicine,it can be used clinically in treating many diseases such as type 2 diabetes mellitus,dyslipidemia,metabolic syndrome,fatty liver and other diseases. Here the current research status and application prospect on 4-Hydroxyisoleucine were summarized.

ObjectiveTo investigate the platelet inhibition ratio by thromboelastography (TEG) and its clinical impact in patients undergoing percutaneous coronary intervention (PCI). Methods118 PCI patients were divided into ischemic events group (22 cases) and nonischemic events group (96 cases) according to their clinical follow-up of 6 months. Platelet inhibition ratio was measured by TEG. ResultsADP-induced platelet inhibition ratio of ischemic events group decreased significantly compared with nonischemic events group (P<0.01). And there were no significant differences in AA-induced platelet inhibition ratio between two groups (P＞0.05). ConclusionThere may be some relationship between the ischemic events of PCI patients and their drug resistance to clopidogrel.
