RESUMO
Importance: Post-stroke sialorrhea (PSS) refers to excessive saliva flowing out the lip border after a stroke. PSS negatively affects patient self-image and social communication and may lead to depression. Limited evidence supports the link between excessive salivation and PSS. No large-scale, strictly controlled randomized controlled trials have shown the effectiveness of acupuncture in treating PSS patients. Objective: We aim to compare the effects of intraoral and sham acupuncture in PSS patients and explore relationships among salivation and drooling severity and frequency and swallowing function in stroke patients. Design: Clinical study protocol, SPIRIT compliant. Setting: Prospective, single-center, randomized, and sham-controlled trial. Population: We will recruit 106 PSS patients to receive 4-week intraoral or sham acupuncture. Additionally, 53 stroke patients without PSS will undergo a conventional 4-week treatment program to compare salivation between PSS and non-PSS patients. Exposures: Intraoral or sham acupuncture. Main Outcomes and Measures: The main evaluation index will be the 3-minute saliva weight (3MSW), comparing changes in 3MSW from baseline to weeks 4 and 8. Secondary assessment indices will include the "Drooling Severity and Frequency Scale" and "Functional Oral Intake Scale." Results: The results from this study will be published in peer-reviewed journals. Conclusion: Comparing effects of intraoral and sham acupuncture in PSS patients, this study may contribute important evidence for future PSS treatment and provide valuable insights into whether salivation issues in stroke patients are attributed to heightened salivary secretion or dysphagia.

BACKGROUND: Although isolated distal deep vein thrombosis (IDDVT) is a clinical complication for acute ischemic stroke (AIS) patients, very few clinicians value it and few methods can predict early IDDVT. This study aimed to establish and validate an individualized predictive nomogram for the risk of early IDDVT in AIS patients. METHODS: This study enrolled 647 consecutive AIS patients who were randomly divided into a training cohort (n = 431) and a validation cohort (n = 216). Based on logistic analyses in training cohort, a nomogram was constructed to predict early IDDVT. The nomogram was then validated using area under the receiver operating characteristic curve (AUROC) and calibration plots. RESULTS: The multivariate logistic regression analysis revealed that age, gender, lower limb paralysis, current pneumonia, atrial fibrillation and malignant tumor were independent risk factors of early IDDVT; these variables were integrated to construct the nomogram. Calibration plots revealed acceptable agreement between the predicted and actual IDDVT probabilities in both the training and validation cohorts. The nomogram had AUROC values of 0.767 (95% CI: 0.742-0.806) and 0.820 (95% CI: 0.762-0.869) in the training and validation cohorts, respectively. Additionally, in the validation cohort, the AUROC of the nomogram was higher than those of the other scores for predicting IDDVT. CONCLUSIONS: The present nomogram provides clinicians with a novel and easy-to-use tool for the prediction of the individualized risk of IDDVT in the early stages of AIS, which would be helpful to initiate imaging examination and interventions timely.

To research databases of Cochrane library, Web of Science, PubMed, FMJS, CBM, VIP, CNKI and Wanfang Data Konwledge Service Platform by computers as at July 5, 2012, which was supplemented with other search results. The findings were included into randomized controlled trials (RCTs) of elemene injection combined with cisplatin chemotherapeuties in treating small cell lung cancer (NSCLC). Data was separately collected by two researchers for literature quality evaluation, and a Meta analysis was made with RevMan 5. 2 software, in order to assess the efficacy and safety of elemene injection combined with cisplatin chemotherapeutics in treating NSCLC. Totally 11 RCTs or 844 cases were included. Meta analysis results suggested that compared with cisplatin chemotherapy alone, the combination of elemene injection and cisplatin chemotherapeutics showed a higher clinical benefit rate ( OR = 2. 03, 95% CI:1.43-2. 88, P <0. 000 1) and a better quality of life (OR = 3.23, 95% CI:2. 20-4. 74, P <0. 000 01). Besides,the combination could also reduce leucopenia (OR =0. 50, 95% CI:0. 33-0. 76, P <0. 001) , and thrombocytopenia (OR =0. 38, 95% CI:0. 16-0. 85, P <0. 02), increase CD4 (MD = 3.32, 95% C1:2. 94-3.70, P <0. 000 01), and CD4/CD8 (MD = 0. 36, 95% CI:0. 28-0. 44, P < 0. 000 01) , and relieve gastrointestinal reactions such as nausea and vomiting (OR = 0. 37, 95% CI: 0. 19-0. 71, P = 0. 003). The analysis indicates that elemene can enhance the chemotherapeutic effect on NSCLC, improve the quality of life, and reduce adverse effect of platinum-contained chemotherapeutics, thereby being worth promoting in clinic.

ETHNOPHARMACOLOGICAL RELEVANCE: Wuling Capsule is a single herbal formula from mycelia of precious Xylaria nigripes (Kl.) Sacc and its pharmacological function have a tranquilizing effect on the central nervous system. The aim of the study to evaluate the efficacy and safety of Wuling capsule in treatment of insomnia. MATERIALS AND METHODS: We performed a multicenter, randomized, double-blind, placebo-controlled study. The participants received either placebo (n=92) or Wuling capsule (n=94) for 4 weeks and a follow-up period for 2 weeks. RESULTS: Compared between pre-treatment and post-treatment, the global Pittsburgh sleep quality index (PSQI) scores in both Wuling capsule group and placebo group improved significantly (P<0.01). However, there was no significant difference between Wuling capsule group and placebo group (P>0.05). Scores of clinical global impressions scale (CGI-I) at each week in Wuling capsule group was similar to those in placebo group (P>0.05). Compared between pre-treatment and post-treatment, scores of the four components of world health organization on quality of life brief scale (WHOQOL-BREF) in both Wuling capsule group and placebo group improved significantly (P<0.01). However, there were no difference between the two groups (P>0.05). The rate of adverse events was 10.10% in Wuling group, and 6.73% in placebo group (P>0.05). CONCLUSIONS: Wuling capsule can improve insomnia when compared with pre-treatment for 4 weeks and be a well tolerated by all the patients at the 6 weeks of study period. However, there are no significant in the results of the variables tested when compared with placebo control. Further additional rigorous randomized clinical trials are still required.

OBJECTIVE: To assess the clinical efficacy, safety and compliance of tianwang buxin decoction (TWBXD) combined with dormancy hygiene education (DHE) and TWBXD alone in treatment of sub-healthy insomnia patients of yin deficiency fire excess syndrome. METHODS: The multi-centered, single blinded randomized clinical trial design was adopted. One hundred and one sub-healthy insomnia subjects of yin deficiency fire excess syndrome were randomly assigned to two groups. The 50 in the treatment group were treated by combined treatment with TWBXD and DHE, while the 51 in the control group were treated with TWBXD alone. The therapeutic efficacy, Pittsburgh sleep quality index (PSQI) score, clinical global impression-improvement (CGI) score, quality of life made by WHO (WHOQOL-BREF) score, and safety in the two groups were compared. RESULTS: The effective rate in the treatment group was 68.08%, lower than that in the control group (75.00%), but the difference between them was statistically insignificant. The PSQI score in the treatment group were reduced from 12.00 +/- 2.25 to 7.55 +/- 2.91 (P < 0.01). It was reduced from 11.68 +/- 2.21 to 7.16 +/- 3.13 in the control group (P < 0.01). The improvement of CGI score and WHOQOL-BREF score was also shown in the two groups after treatment (P < 0.01). No significant difference was shown in each index between the two groups. There was no significant difference in CGI between two weeks after drug withdrawal and by the end of the therapeutic course in the same group (P > 0.05). There was no statistical significance in inter-group comparison (P > 0.05). CONCLUSION: Significant effect was achieved by TWBXD combined with DHE and by TWBXD alone. Their efficacies were equivalent, with high compliance and safety.

OBJECTIVE: To study Chinese medicine syndrome features in sub-health insomnia patients, and to make clear the symptom compositions of each syndrome, thus providing references for main and minor symptoms selection, and establishing a syndrome differentiation system in clinical testing. METHODS: Chinese medicine syndrome information was collected by multi-centered large-sample clinical data. The information was statistically managed to get common syndrome types, symptoms compositions, and the Pittsburgh Sleep Quality Index (PSQI) scores of sub-health insomnia patients. RESULTS: The most common symptoms of sub-health insomnia patients of yin deficiency fire hyperactivity syndrome and Xin-Pi deficiency syndrome cover difficulties in falling asleep, early awakening, dreaminess, sometimes sleeping sometimes awake, failing in falling into sleep when wake up, failing in sleep all night. There was insignificant difference between the two syndrome types (P>0.05). Some unique symptoms occurred in the two syndrome types as minor symptoms. Fatigue, abdominal distension after eating occurred in patients of Xin-Pi deficiency syndrome. Burning sensation of five centers, irritability, etc. occurred in patients of yin deficiency fire hyperactivity syndrome. Significant difference was shown in minor symptoms (except irritability, vexation, frequent urine) (P<0.05, P<0.01). No significant difference was shown in PSQI score between the two syndrome types (P>0.05). But significant difference was shown in sleep disturbance factors (P<0.05). Patients of yin deficiency fire hyperactivity syndrome had severe sleep disturbance factors. CONCLUSION: There was no significant difference in main symptoms between the two syndrome types. Some unique symptoms occurred in the two syndrome types as minor symptoms. There was difference in sleep quality compositions.

OBJECTIVE: To establish an ischemia-reperfusion injury model of rat cerebral microvascular endothelial cells (MVECs) in vitro, and to explore the relationship between nuclear factor-kappa B (NF-kappaB) and the protective effects of Qingkailing effective components (hyocholic acid, taurocholic acid, baicalin, jasminoidin, Pinctada martensii) on MVECs. METHODS: Brain MVECs of male rats were digested with trypsin and subcultured, then the content of MVECs was adjusted to 1x10 (5)/mL and the MVECs were divided into normal control group, untreated group, hyocholic acid group, taurocholic acid group, baicalin group, jasminoidin group, Pinctada martensii group and nimodipine group, with six holes in each group. Except for the normal control group, the MVECs in the other groups were exposed in oxygen and glucose deprivation (OGD) circumstance in vitro to simulate ischemia-reperfusion injury. Immunocytochemical staining and image analysis system were used to observe the expression of NF-kappaB protein. RESULTS: Under a light microscope, the nuclei of MVECs in the normal control group were blank. Staining intensity of NF-kappaB protein in the nucleus in the untreated group was much deeper than that in the endochylema, with NF-kappaB shifted to nucleus after activation; a small quantity of NF-kappaB protein were expressed in the border of nucleus next to endochylema in groups of Qingkailing effective components, and the NF-kappaB protein expression was weaker than that in the untreated group. With the image analysis, we found that transmittance of nucleus and endochylema in the untreated group was significantly lower than that in the normal control group (P<0.01). Transmittance of nucleus and endochylema in the treated groups was higher than that in the untreated group (P<0.05, P<0.01). CONCLUSION: Qingkailing effective components have significant effect in inhibiting NF-kappaB protein transferring from endochylema to nucleus in vitro.

OBJECTIVE: To investigate the protective mechanism of geniposide, baicalin and berberine on hypoxia and reoxygenation injury in cultured rat cerebral microvascular endothelial cells. METHOD: To establish a model of hypoxia four hours and reoxygenation twelve hours injury in rat cerebral microvascular endothelial cells in vitro. The injured cells were treated with geniposide (0. 128, 0.064, 0.032 micromol mL(-1), baicalin (0.028, 0.014, 0.007 micromol mL(- 1)) and berberine (0.024, 0.012, 0.006 micromol mL(-1)). The expression of p65 subunit of NF-kappaB was detected by immunocytochemical assay and techniques of image quantitative analysis. The protein expression of NF-kappaB was calculated with the mean optical density and mean area. The nuclear translocation of NF-kappaB was calculated with the percentage of positive cells and ratios of light transmittance of cytoplasm and cell nucleus. RESULT: Compared with the normal group, both the protein expression and the nuclear translocation of NF-kappaB of model group were significant increased (P <0.01). Compared with the model group, the mean optical density of all treated groups was decreased ,but these was no significant difference between them. As compared with model group, the mean area of all treated groups was significant decreased (P < 0.01). The percentage of nuclear translocation of all treated groups is not only lower than that of the model group but higher than that of the normal group (P <0.01). Compared with the model group, the ratios of light transmittance of cytoplasm and cell nucleus of all treated groups was significantly elevated (P <0.01). CONCLUSION: The results suggesed that geniposide, baicalin and berberine could protect hypoxia/reoxygenation injuried rat cerebral microvascular endothelial cells injury. One of the mechanism may lie in inhibiting both the protein expression and the nuclear translocation of NF-kappaB.

OBJECTIVE: To investigate the protective mechanism of geniposide, baicalin and berberine on hypoxia and reoxygenation injury in cultured rat cerebral microvascular endothelial cells. METHOD: A model of four hours hypoxia and twelve hours reoxygenation injury in rat cerebral microvascular endothelial cells in vitro was established. The injured cells were treated with geniposide (0.128, 0.064, 0.032 mmol x L(-1)), baicalin (0.028, 0.014, 0.007 mmol L(-1)) and berberine (0.024, 0.012, 0.006 mmol L(-1)), respectively. The immunocytochemical method and techniques of image quantitative analysis were used to detect the mean optical density and mean area in order to match the protein expression of VCAM-1. The method of RT-PCR was adopted to observe and match the mRNA expression of VCAM-1. RESULT: As compared with the normal group, the mean optical density, the mean area and the mRNA expression of VCAM-1 of model group were significant increased (P < 0.01, P < 0.01, P < 0.01). As compared with the model group, both the mean optical density and the mean area of all treated groups were decreased, and there was significant difference between them (P < 0.01, P < 0.01). As compared with normal group, the mean optical density of baicalin (0.007 mmol x L(-1)) and berberine (0.012, 0.006 mmol x L(-1)) were significant decreased (P < 0.05, P < 0.01, P < 0.01), but there was no significant difference between the other groups and the normal group. As compared with normal group, the mean area of baicalin (0.0014 mmol x L(-1)) was significant decreased (P < 0.05), but there was significant difference between the other groups and the normal group. The mRNA expression of all treated groups was not only lower than that of the model group but also higher than that of the normal group (P < 0.05, P < 0.05). CONCLUSION: The results suggest that geniposide, baicalin and berberine, which are effective compositions of huanglian jiedu decoting, can protect hypoxia-reoxygenation injuried rat cerebral microvascular endothelial cells. One of the protected mechanisms is that they can inhibit the expression of VCAM-1.

OBJECTIVE: To establish an in vitro injury model of ischemia-reperfusion in cerebral microvascular endothelial cells of rats and observe the protective effect of cholic acid. METHOD: Cultured rat microvascular endothelial cells were subjected to the oxygen-glucose deprivation (OGD) (Krebs solution) and recovery of oxygen-glucose, which simulated in vitro ischemia and reperfusion injury, and treated with cholic acid. The A value was measured with MIT chromatometry. RESULT: Cultured cells were impaired after OGD for 4 hours and recovery of oxygen-glucose for 12 hours, the A value of the cells treated with cholic acid was significantly higher than that of the cells without treatment (P < 0.01). CONCLUSION: Cholic acid could obviously protect rat cerebral microvascular endothelial cells from injury induced by an in vitro ischemia-reperfusion.
