ABSTRACT
OBJECTIVE@#To dynamically observe the levels and activities of von Willebrand factor (vWF) and ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) in plasma of children with congenital ventricular septal defect (VSD) during perioperative period, and explore the value of plasma vWF antigen (vWF:Ag) and ADAMTS-13 activity (ADAMTS-13: AC) in evaluating vascular endothelial injury and prognosis in children with VSD.@*METHODS@#In this cross-sectional study, a total of 74 children with VSD who underwent surgical treatment in TEDA International Cardiovascular Hospital from September 2018 to March 2019 were enrolled in the observation group. Among them, there were 28 cases of pure VSD, 32 cases of VSD combined with pulmonary hypertension, and 14 cases of VSD combined with valvular heart disease. 31 healthy children who underwent physical examination in Tianjin Children's Hospital during the same period were collected as the control group. The biochemical indexes of the children at admission were recorded. Peripheral plasma was collected at admission, postsurgery day 0 and day 1, respectively, and the levels of vWF activity (vWF:AC), vWF:Ag, ADAMTS-13 antigen (ADAMTS-13:Ag) and ADAMTS-13:AC were detected.@*RESULTS@#The level of plasma vWF:Ag and vWF:AC in the observation group before surgery were significantly lower than those in the control group (P<0.001), and increased continuously, on postsurgery day 0 and day 1 (P<0.001). The level of ADAMTS-13:Ag in the observation group before surgery was significantly higher than that in the control group (P<0.001), which decreased significantly on postsurgery day 0 (P<0.001), and increased significantly on postsurgery day 1 compared with postsurgery day 0 (P=0.033). The level of ADAMTS-13:AC in the observation group before surgery was significantly lower than that in the control group (P=0.015), which decreased significantly on postsurgery day 0 (P=0.037), and increased on postsurgery day 1, but the difference was not statistically significant (P=0.051). The changes of vWF and ADAMTS-13 in the three subgroups were basically similar to the observation group. vWF: Ag/ADAMTS-13: AC ratio on postsurgery day 0 and day 1 had high diagnostic value in vascular endothelial injury (AUC=0.80, P<0.001; AUC=0.93, P<0.001). Preoperative vWF and ADAMTS-13 levels, and related baseline indicators were not correlated with postoperative infection, bleeding, thrombosis,etc.@*CONCLUSION@#Preoperative vWF: Ag, vWF: AC and ADAMTS-13: AC levels in children with VSD are low, while the level of ADAMTS-13: Ag is high. After surgery, the levels of vWF: Ag and vWF: AC are increased and the level of ADAMTS-13: Ag is decreased. The postoperative vWF: Ag/ADAMTS-13: AC ratio shows high diagnostic value in evaluating vascular endothelial injury. There is no correlation between preoperative vWF and ADAMTS-13 levels with perioperative clinical events.

Cionbufagin has anti-inflammatory and analgesic effects. It is of great value in the treatment of bone cancer pain, but its mechanism is still unclear. To generate a bone metastasis model of breast cancer, 4×105 Walker-256 cells were inoculated into the left hind limb of SD rats. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Medical College of China Three Gorges University. Rats were randomly divided into sham, model, cionbufagin, morphine, saline, minocycline, microglia inhibitor (RS102895) and co-treatment with cionbufagin and minocycline group. The cionbufagin (5 mL·kg-1, i.p.), morphine (8 mg·kg-1, i.p.) and co-treatment groups (included cionbufagin 5 mL·kg-1, i.p.) received continuous administration from day 9 to day 21. The saline, minocycline (2.5 μg·μL-1, 20 μL), RS102895 (1.5 μg·μL-1, 20 μL) and co-treatment groups (included minocycline 2.5 μg·μL-1, 20 μL) received continuous administration by intrathecal cannulation from day 12 to day 21. Bone destruction of the left hind limb of rats was detected by hematoxylin-eosin staining (H&E). The pain threshold before treatment and at day 2, 5, 7, 9, 12, 14, 17 and 20 was measured by behavioral indexes. Activation and expression of a microglia marker (Iba-1) was determined by immunofluorescence and Western blot. The level of tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6) in rat spinal cord was measured by enzyme-linked immunosorbent assay (ELISA). H&E results showed that cionbufagin effectively inhibited the destruction of bone marrow in rats with bone cancer pain; cionbufagin treatment significantly increased the mechanical and thermal pain threshold. Immunofluorescence showed that cionbufagin effectively inhibited the activation of microglia in the spinal dorsal horn. Western blot analysis confirmed that the activation of microglia in the spinal dorsal horn was inhibited by cionbufagin treatment. It was also found that the CCL2/CCR2 pathway may be involved in the analgesic effect of cionbufagin. These results suggest that cionbufagin can effectively alleviate bone cancer pain, possibly by inhibiting the release of inflammatory factors and the activation of spinal microglia cells through the CCL2/CCR2 pathway.
ABSTRACT
Objective:Metabolomics was used to analyze the brain tissue samples of model mice with chronic unpredictable mild stress (CUMS) depression, in order to find out the differential metabolites related to depression and to explore the possible antidepressant mechanism of iridoid part of Valerianae Jatamansi Rhizoma et Radix (IEFV). Method:Forty-two Kunming mice were randomly divided into 6 groups, including the normal group, the model group, the fluoxetine group (2.5 mg·kg-1) and the IEFV low, medium, and high dose groups (doses were 5.73, 11.47, 22.94 mg·kg-1, respectively). The behavioral and biochemical indicators of CUMS model mice were used for pharmacodynamic evaluation with IEFV and a positive drug (fluoxetine) as the intervention drugs. Then, the effect of IEFV on endogenous substances of the brain tissue in CUMS model mice were analyzed by nuclear magnetic resonance hydrogen spectrum (1H-NMR) metabolomics, and multivariate statistical analysis was used to identify the differential metabolites and to enrich the metabolic pathways involved in the differential metabolites. Result:After modeling, the immobility time of the model mice increased significantly, their sucrose preference rate and the excitatory neurotransmitters [5-hydroxytryptamine (5-HT) and norepinephrine (NE)] decreased significantly, indicating the success of modeling. The depression was relieved after IEFV administration, mainly manifested by the recovery of the immobility time, sucrose preference rate and the excitatory neurotransmitters (5-HT and NE). Principal component analysis (PCA) of endogenous metabolites in brain tissue showed that the model group could be significantly separated from the normal group, while the IEFV groups and fluoxetine group all showed a trend of deviating from the model group to the normal group, which was consistent with the behavioral results. The results of orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 16 different metabolites between the model group and the normal group, including 12 water-soluble metabolites and 4 liposoluble metabolites. Seven potential metabolism pathways were obtained through MetPA analysis, including metabolism of phenylalanine, metabolism of phenylalanine, tyrosine and tryptophan, metabolism of taurine and hypotaurine acid, metabolism of alanine, aspartic acid and glutamic acid, biosynthesis of valine, leucine and isoleucine, metabolism of D-glutamine and D-glutamate and tricarboxylic acid cycle (TCA). IEFV-high dose group could significantly recall 11 differential metabolites. Conclusion:IEFV may play an antidepressant role mainly by affecting energy metabolism, amino acid metabolism and neurotransmitter levels, which provides a reference for further study on the antidepressant mechanism of IEFV.
ABSTRACT
Psychiatric diseases represented by depression have gradually become one of the major health problems of people in the fast-paced, high-pressure society. Severe cases can cause suicides, huge harm or disaster to families and the society. Although modern medicine has made great progress in the field of anti-depressant drug therapy, depression still cannot be cured. At the same time, traditional Chinese medicines(TCM) with a definite curative effect, few adverse reactions, and mild efficacy have received increasing attention. TCM valerianae Jatanmansi Rhizoma et Radix has been widely used to alleviate sleep disorder, and its root extract is popularly known as valerian and used as a mild sedative for a long time in European. Tagara takes Valerianae Jatamansi Rhizoma et Radix as the key ingredient for treatment of depression-type insomnia, and is available abroad. It is reported that iridoid, sesquiterpenes, flavonoids or extract from Valerianae Jatamansi Rhizoma et Radix has a superior anti-depression activity in both animal and clinical trials, and the mechanism is mainly related to the regulation of neurotransmitters in the brain, the improvement of the function of the hypothalamic-pituitary-adrenal (HPA) axis, the resistance of free radicals and inflammation, and the neuroprotective effect. However, there is still lack of report on the anti-depression system and in-depth research of Valerianae Jatamansi Rhizoma et Radix. Therefore, it is urgently necessary to systematically collect and summarize the anti-depressant activity and explain the relevant mechanisms, so as to provide reference for the further development of Valerianae Jatamansi Rhizoma et Radix medicinal resources.
ABSTRACT

ABSTRACT
In recent years, a new type of organic cation transporter has been found to transport organic cation drugs like pyrilamine, diphenhydramine and oxycodone in brain capillary endothelial cells, Caco-2 cells and other cells. Its transport activity can not be inhibited by typical organic cation transporter substrates or inhibitors, and its transport characteristics are different from those reported for the organic cation transporters, such as organic cation transporters (OCTs), organic cation/carnitine transporters (OCTNs), multidrug and toxin extrusion transporters (MATE) and the plasma membrane monoamine transporter (PMAT). It is a novel organic cation transporter, called pyrilamine-sensitive H+/OC antiporter. This review will present a comprehensive summary to elaborate the transport characteristics, structure of the substrates, tissue expression and the differences with other organic cation transporters.

<p><b>OBJECTIVE</b>To assess the risk of local transmission of Dengue caused by introduced cases with semi-quantitative method in 2015 in Zhejiang Province.</p><p><b>METHODS</b>Risk indexes of local transmission of Dengue caused by introduced cases were reviewed. The weights of indexes were computed by analytic hierarchy process and further used to generate absolute risk values by multiplying indexes. Moreover, comprehensive indexes were computed to describe relative risk by combining analytic hierarchy process and TOPSIS methods.</p><p><b>RESULTS</b>Four primary indexes and 19 secondary indexes were identified for risk assessment of local transmission of Dengue. The indexes with maximum and minimum weight were the number of immigration from countries with Dengue patients (weight value: 0.0678) and density of population (weight value: 0.0371) respectively. All CR values, statistics for measuring consistency of score matrix, were less than 0.1 (minimum: 0.000, maximum: 0.0922, average: 0.0251). The absolute risk of Zhejiang Province was within the range of 0.397-0.504 (the full score was 1.0). The risk orders of 11 municipalities sorted by relative comprehensive indexes and absolute risk values methods were similar. The three highest municipalities were Hangzhou, Wenzhou and Ningbo and the ranges of absolute risk value were 0.387-0.494, 0.404-0.511 and 0.392-0.499 respectively.</p><p><b>CONCLUSION</b>The results provides scientific basis for preventing and controlling Dengue in Zhejiang Province. The indexes and weights may be used to assess risk of Dengue in future. In addition, the semi-quantitative method constructed in this study would be a significant reference for risk assessment of public health in emergencies.</p>

OBJECTIVE: To assess the feasibility of visualizing hand and foot tendon anatomy and disorders by Gemstone Spectral Imaging (GSI) high-definition CT (HDCT). MATERIALS AND METHODS: Thirty-five patients who suffered from hand or foot pain were scanned with GSI mode HDCT and MRI. Spectrum analysis was used to select the monochromatic images that provide the optimal contrast-to-noise ratio (CNR) for tendons. The image quality at the best selected monochromatic level and the conventional polychromatic images were compared. Tendon anatomy and disease were also analyzed at GSI and MRI. RESULTS: The monochromatic images at about 65 keV (mean 65.09 +/- 2.98) provided the optimal CNR for hand and foot tendons. The image quality at the optimal selected monochromatic level was superior to conventional polychromatic images (p = 0.005, p 0.05), compression (chi2 = 0.5, p > 0.05), absence (chi2 = 0, p > 0.05) and rupture (chi2 = 0, p > 0.05). GSI was significantly less sensitive than MRI in displaying tendon adhesion (chi2 = 4.17, p < 0.05), degeneration (chi2 = 4.17, p < 0.05), and tendinous sheath disease (chi2 = 10.08, p < 0.05). CONCLUSION: GSI with monochromatic images at 65 keV displays clearly the most hand and foot tendon anatomy and disorders with image quality improved, as compared with conventional polychromatic images. It may be used solely or combined with MRI in clinical work, depending on individual patient disease condition.

<p><b>BACKGROUND</b>As a treatment of depression, the efficacy of conventional repetitive transcranial magnetic stimulation (rTMS) is limited, and symptoms recurrence is easy to occur after the treatment. This study aimed to examine the efficacy and safety of sleep electroencephalogram modulated repetitive rTMS (SEM-rTMS) in the treatment of depression.</p><p><b>METHODS</b>After 7 days without psychoactive medication, 164 patients with clinically defined depression were randomly divided into 3 groups: SEM-rTMS group (n = 57), conventional rTMS (C-rTMS, n = 55) group and sham-rTMS group (n = 52). Every patient was treated with the corresponding method for 30 minutes everyday for 10 days. Before and after scores on the 24-item Hamilton rating scale for depression (HAMD-24) and the clinical outcome on the 10th day of therapy for all subjects were analyzed.</p><p><b>RESULTS</b>Twenty-two cases in the SEM-rTMS group obtained improved mood as compared to 6 in the C-rTMS group and 2 in the sham-rTMS group (χ(2) = 15.89, P = 0.0004). After completion of the rTMS phase of the protocol, a (51 ± 5)% reduction of HAMD-24 scores from the baseline in the SEM-rTMS group was found compared with a (34 ± 4)% in the C-rTMS group (q = 26.09, P = 0.001) and a (14 ± 3)% in sham-rTMS group (q = 57.53, P = 0.000). The 88% total effective rate in the SEM-rTMS group was significantly higher than 68% in the C-rTMS group and 20% in the sham-rTMS group (χ(2) = 12.01, P = 0.0025). No significant side effects were noted.</p><p><b>CONCLUSION</b>SEM-rTMS is an effective and safe way for treating depression with repetitive transcranial magnetic stimulation (ChiCTR-TRC-00000438).</p>
