Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

Objective To investigate the clinical role of central venous pressure(CVP) to evaluate fluid responsiveness in septic shock patients. Methods 66 septic shock patients were studied, every patient was administered a volume challenge, before and after it, CVP, intrathoracic blood volume index (ITBVI),global end-diastolic volume index(GEDVI), cardiac index(CI), stroke volume index(SVI) were measured by PiCCO method. All the obtained values were analyzed by statistics method. Results Initial CVP in responders is significantly different from that in nonresponders; △ITBVI, △GEDVI, △CI, △SVI, △HR (△:changes) before and after volume challenge in responders were significantly different from those in nonresponders; the significance of △ITBVI, AGEDVI to predict volume responsiveness was strong indicated by high values of areas under the receiver operating characteristic curves (0.674 and 0.700, respectively).If patients were regrouped by CVP≤11 mm Hg(1 mm Hg=0.133 kPa) and CVP > 11 mm Hg, initial ITBVI and GEDVI in responders were not significantly different from that in nonresponders; △ITBVI,△GEDVI, △CI, △SVI before and after volume challenge in responders were significantly different from those in nom'esponders. Conclusion In septic shock patients, CVP play a guidance role to predict and evaluate volume responsiveness and when CVP was > 11 nun Hg, a positive response will be less likely. Initial volumetric parameters(intrathoracic blood volume and global end-diastolic volume) play a questionable role in predicting and evaluating volume responsiveness, changes before and after volume challenge maybe helpful.

Objective:To determine if suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of botulinum neurotoxin serotype A (BoNT/A) DNA vaccines in mouse model. Methods:Vaccination of mice i.m. with plasmid DNA replicon vaccine pSCARSHc and conventional plasmid DNA vaccine pcDNASHc following electric pulses and with DNA and bupivacaine complexes. AHc-specific group antibody ELISA titers and lymphocyte proliferative responses of mice were detected and IgG1 and IgG2a isotype profiles were assayed. Results:Immune effects of DNA vaccines were enhanced following electric pulses and bupivacaine delivery. Effects of DNA vaccines following electric pulses were better than that of DNA vaccines formulated with bupivacaine,and the combined delivery technology of electric pulses and bupivacaine induced the highest level of specific antibodies and lymphocyte proliferative responses. Plasmid DNA replicon vaccine pSCARSHc induced relatively higher AHc-specific antibodies and lymphocyte proliferative responses in immunized Balb/c mice than conventional plasmid DNA vaccine pcDNASHc in these DNA delivery technologies. And vaccine pSCARSHc induced Th2/Th1-type immune responses with a general bias to Th2-type,and vaccine pcDNASHc induced Th2-type immune responses. Conclusion:Suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of BoNT/A DNA vaccines in mouse model. Therefore,the methods described here potentially provide suitable strategies in developing an efficacious vaccine against botulinum neurotoxin serotype A.

Objective: To observe the therapeutic effect of mild moxibustion on irritable bowel syndrome (IBS) visceral hyperalgesiamodel rats and its regulatory effect on P2X3 receptors in the spinal cord, anterior cingutate cortex (ACC) and thalamic ventral posterolateral nucleus (VPL). Methods: Thirty 8-day-old newborn rats were randomly divided into a normal group (n=6) and a modeling group (n=24) according to the completely random number table method. Rats in the normal group were bred routinely, and those in the modeling group were subjected to preparing IBS chronic visceral hyperalgesia model using colorectal distention (CRD) in stimulation method. Rats successfully modelled were re-divided into a model group, a mild moxibustion group, a P2X3 receptor antagonist group, and a normal saline group according to the completely random number table method with 6 rats in each group. Rats in each group received corresponding interventions from the 37-day old, once a day for 7 consecutive days. Immunohistochemistry and Western blot assays were used to detect P2X3 protein expressions in the spinal cord, ACC and VPL of rats. Results: Under different intensities of CRD stimulation, the abdominal withdrawal reflex (AWR) scores of the model group were significantly increased versus the normal group (all P<0.05); the AWR scores of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). The P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the model group were significantly increased versus the normal group (all P<0.01); the P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). Conclusion: Mild moxibustion can inhibit the P2X3 receptor expressions in the spinal cord, ACC, and VPL tissues of IBS visceral hyperalgesia model rats, which may be the mechanism of mild moxibustion in relieving the central sensitization of rats with IBS visceral hyperalgesia.

Purpose To explore the expression of CBX8 in gastric adenocarcinoma tissue and its clinical significance.Methods 119 cases of primary gastric adenocarcinoma treated by surgery and corresponding adjacent normal tissues were collected. The protein expression levels of CBX8 in gastric adenocarcinoma and their corresponding adjacent normal tissue was determined using tissue microarray and immunohistochemistry PV 6000 method staining. The relationship between CBX8 expression and clinicopathologic characters and survival prognosis was analyzed. Results The positive expression rate of CBX8 in gastric cancer and their corresponding adjacent normal tissue was 46.2% (55/119) and 13.4% (16/119) respectively. There was statistically significant difference between two groups (χ2=30.53, P < 0.01). The expression of CBX8 in gastric adenocarcinoma tissue was obviously correlated with the differentiation, clinical staging, and lymph node metastasis (P < 0.05). The high expression rate of CBX8 in the poorly differentiated gastric adenocarcinoma was lower than moderately differentiated and well differentiated group. The high expression rate of CBX8 in stage Ⅰ + Ⅱ gastric adenocarcinoma was higher than that in stage Ⅲ + Ⅳ. The gastric adenocarcinoma patients with high expression of CBX8 had low metastasis rate. Cox multivariate analysis showed CBX8, clinical staging, and lymphatic metastasis were independent predictors of overall survival and disease-free survival (P < 0.05). Kaplan-Meier analysis showed that the patients with higher expression of CBX8 had both longer overall survival time (P = 0.004) and disease-free survival time (P =0.004). Conclusion The expression of CBX8 may be involved in the tumorigenesis and progression of gastric adenocarcinoma. CBX8 is one of the independent predictor of prognosis, and the detecting of CBX8 expression may have important clinical value for the evaluation of gastric adenocarcinoma. CBX8 may became a new target for target therapy of gastric adenocarcinoma.
