Objective To observe the clinical efficacy of ginger-partitioned moxibustion in improving blood flow velocity in lower limbs of post-stroke patients.Methods Ninety post-stroke patients were randomized into a treatment group and a control group, 45 in each group. The treatment group was intervened by ginger-partitioned moxibustion, while the control group was by conventional acupuncture. Before and after intervention, the blood flow velocity in lower limbs, National Institute of Health Stroke Scale (NIHSS) and modified Barthel Index (MBI) were evaluated.Results After 4-week treatment, the maximum blood flow velocity (Vmax) was significantly changed in the treatment group (P<0.05), and there was a significant difference in comparing the Vmax between the two groups after intervention (P<0.05); the NIHSS and MBI scores were significantly changed after intervention in the treatment group (P<0.05), and there was a significant difference in comparing MBI score between the two groups after intervention (P<0.05).Conclusions Ginger-partitioned moxibustion can accelerate the blood flow velocity in lower limbs of the post-stroke patients, improve blood circulation and the activities of life.

Existing antidepressants exhibit delayed onset of action,which can decrease the compliance of the patients and enhance the risk of suicide.How to produce early-onset antidepressants with higher efficacy and lower adverse reactions has become a crucial point in the research of antidepressants.It has been demonstrated that selective 5-HT1Aantagonist,?2 antagonist and 5-HT2Aantagonist can accelerate the response of classic antidepressants.Furthermore,5-HT/NE dual reuptake inhibitor and 5-HT/NE/DA triple reuptake inhibitor can also produce early onset of action.Here,several reasons for the delayed onset of action and the progress in the development of early-onset antidepressants are reviewed.

Studying the essence of syndromes (Zheng) in traditional Chinese medicine (TCM) is a fundamental challenge in basic theoretical research of TCM. The relationship between any given syndrome and biochemical indicators is one of the important aspects of the study. As the indexes selected in each study are specific to a particular Western medical disease diagnosis, and the disease factor is inevitably introduced into the study, the effect of disease factor on the index changes cannot be assessed effectively by traditional data processing methods. This is known as "the same syndrome with different reasons", which has resulted in confusion in TCM research. This study aimed at providing a mathematical tool to address this issue. Based on information theory and the residual-split method, the syndrome information, which was covered in the index variation, was quantitatively calculated in this paper as an independent part of the disease factor. A mathematical model capable of objectively assessing and statistically testing the effect of the syndrome factor on the index changes was established. Applying this model to literature data of studies on the relationship between cyclic nucleotides and yang-deficiency syndrome showed following results. First, the values of yang-deficiency syndrome information were negative for cyclic adenosine monophosphate (cAMP) while positive for cyclic guanosine monophosphate (cGMP) in all included literature. This indicated that the group of yang-deficiency syndrome was correlated with an obvious trend of reduced cAMP levels and increased cGMP levels. Second, the statistical test results of yang-deficiency syndrome information of the two indexes were different among the literature included. The quality of original data was considered as a possible reason. Third, the significant differences between the yang-deficiency group of a specific disease and the normal group may, in some cases, be caused by a disease factor rather than a syndrome factor. The mathematical model provided a reasonable mathematical tool for the analysis of disease factor and syndrome factor in clinical research of TCM, suggesting that the mathematical model may give rise to innovative ideas and methods in the study of syndromes.

Objective To assess renal perfusion of chronic renal failure(CRF) at different stages in rabbits by contrast-enhanced ultrasound. Methods Fifteen rabbits were injected cationic bovine serum albumin(C-BSA) intravenously for 8 weeks to establish CRF models. Serum creatinine(Scr) and blood urea nitrogen(BUN) were determined before injection and 2,4,6,8 weeks after C-BSA injection respectively. The size of kidney was measured by two-dimensional ultrasound and contrast-enhanced ultrasound was performed on bilateral kidneys at the same time points. Renal perfusion was analyzed quantitatively with the time intensity curve. Results Renal cortical perfusion reduced started at 4weeks after injection,manifested as the peak signal intensity(PSI) of the time-intensity curve parameters decreased(P<0.05 or P <0.01). The speeds of perfusion and clearance of kidney were slower,showed as the time to peak intensity(PIT) and the time to half of peak intensity(HPT) delayed (P <0.05 or P <0.01). Compared with pre-injection, there were no differences in terms of the area under the curve(AUC) at 2,4 and 6 weeks after injection (all P> 0.05). And compared with pre-injection,2,4,6 weeks after injection, the AUC decreased at 8 weeks (P < 0.05 or P <0.01 ). The level of Scr and BUN of rabbits had increased since 6 weeks after injection (P< 0.05 or P <0.01). Two-dimensional ultrasound showed the renal volume was enlarged and the cortex was thickened from 2 weeks to 6 weeks after injection (P<0.05 or P <0.01). At 8 weeks after injection, the renal size had decreased as well (P < 0.05). These ultrasound changes were in accordance with its pathological changes. Conclusions Contrast-enhanced ultrasound in combination with time-intensity curve can quantitatively analyze the renal perfusion of CRF at different stages. The reduction of renal perfusion was earlier than the changes of routine laboratory indexes in rabbits with CRF. The haemodynamic changes of CRF rabbit were closely related with its pathological changes.

OBJECTIVE To explore the antidepressant effect and the underlying mechanisms of schisandrin (SCH), a component of the fruits of Schizandra chinesis. METHODS The forced swimming test (FST) and tail suspension test (TST) in mice were used to evaluate the antidepressant activity of SCH (5, 10, and 30 mg · kg-1) following single administration intragastrically, and the locomotor activity was investigated to exclude its neural excitatory effects. Effects of SCH on neural monoamine systems were studied in two pharmacological models, including reserpine induced monoamine depletion test and yohimbine toxicity potentiation test. RESULTS In behavioral despair models, SCH (30 mg·kg-1) signif?icantly decreased the immobility time in the TST and FST (P<0.05) compared with normal control group. Results of the locomotor activity experiment showed that SCH had no excitatory or inhibitory actions on the central nervous system. In the reserpine reversal experiment, SCH (30 mg · kg-1) antagonized thepalpebral ptosis and akinesia symptoms caused by reserpine(2.5 mg · kg-1) treatment (P<0.05) compared with model group, but had little effect on the drop of the anal temperature. Moreover, SCH did not increase the lethality caused by subcutaneous injection of yohimbine (30 mg · kg-1)at the threshold lethal dosage. CONCLUSION SCH exerts potential antidepressant-like effect in mice.

Objective To make a systematic evaluation of the efficacy and safety of Eszopiclon and Alprazolam in the treatment of insomnia.Methods By searching the PubMed,Cochrance Library,CNKI, WANFANG,and VIP database,we studied the literature published between 2005 to 2016 on the efficacy and safety of Eszopiclon and Alprazolam in the treatment of insomnia.We collected the randomized controlled trials (RCTs), evaluated the quality of methods and then analyzed the data using RevMan5.3 software.Results A total of 18 RCTs were included,involving 2088 patients.According to Meta-analysis,Eszopiclon group had a significantly higher total efficacy rate [RR=1.07,95% CI (1.02,1.11),P=0.003],lower severity of adverse reactions [MD=-0.43,95% CI(-0.75,-0.12),P=0.008]and incidence of adverse reactions [RR=0.46,95% CI(0.32, 0.66),P<0.0001]than Alprazolam group.However,the two groups did not significantly differ in sleep quality scores after 4-week teatment [MD=-0.05,95% CI(-0.22,0.12),P=0.54].Conclusion Eszopiclon is more effective on insomnia than Alprazolam,with better safety,and it deserves wide clinical use.

Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research.
