Meta analysis for insomnia Guizhi Gancao Longgu Muli decoction for insomnia A meta-analysis.

BACKGROUND: Guizhi Gancao Longgu Muli Decoction can make a good effect on the insomnia under the catalogue of traditional Chinese medicine. METHOD: To search the databases:Pubmed, Web of Science, EMBASE, the Cochrane Library, the China National Knowledge Infrastructure (CNKI), the China Biology Medicine disc (CBMdisc), the China Science and Technology Journal Database (VIP), the Wanfang. RESULTS: Fifteen randomized controlled trials were included, totally including 1164 participants. After summarizing the observational index revised according to the "Guiding Principles for Clinical Research of New Chinese Medicines", we found that the curative effect of the trial group is 2.29 times that of the control group in the fixed effect model which had a statistically significant difference [OR = 2.293681, 95%CI = 0.3266112-5.83]. And the Pittsburgh Sleep Quality Index (PSQI) which had 7 different dimensions, including subjective sleep quality[p = 0.001 < 0.05], sleep latency, sleep duration[p = 0.000 < 0.05], habitual SE[p = 0.000 < 0.05], sleep disorders[p = 0.002 < 0.05], use of sleep medications[p = 0.000 < 0.05], and daytime dysfunction[p = 0.000 < 0.05], showed a higher scores in the trial group than the one in the control group in every dimension. The final results of the total scores in PSQI also showed a higher scores in trial group with a p = 0.000 < 0.05 (Test of WMD), suggest a statistically significant difference. While the adverse effects showed a lower rate in the trial group than the one in the control group under a fixed-effect model, with a p = 0.000 < 0.05, indicate a statistically significant difference. CONCLUSION: The efficacy and safety of GGLMD in the trial groups are better than the modern western medicine in the control groups.

Diagnosis of Hirschsprung disease by hydrocolonic sonography in children.

OBJECTIVES: To compare hydrocolonic sonography with histopathology for diagnosing children with symptoms highly suggestive of Hirschsprung disease (HD). METHODS: In this prospective study, patients presenting refractory constipation highly suggestive of HD underwent hydrocolonic sonography with retrograde infusion of saline into the colon. The dilated segments, narrowed segments, luminal diameter ratio, transition zone (TZ), thickening, and blood perfusion of the upstream bowel were evaluated. The sensitivity and specificity of combined and single parameters were determined in comparison with biopsy. RESULTS: One hundred and three children were included in this study; 49 were confirmed to have HD. The luminal diameter ratio showed superiority over other parameters. An area under the curve (AUC) of 0.969 (95% confidence interval [CI]: 0.936-1.000) and a cutoff value of 1.51 were established by receiver operating characteristic (ROC) curve analysis of the luminal diameter ratio (sensitivity: 89.8%; specificity: 96.3%). By combining the luminal diameter ratio as the major criterion with two minor criteria, hydrocolonic sonography showed the same sensitivity (91.8%) and better specificity (96.3% vs 87%) than contrast enema, but this difference was not statistically significant (p = 0.063). Consistency analysis showed a kappa value of 0.825 (p < 0.001), indicating excellent agreement between hydrocolonic sonography and contrast enema. CONCLUSIONS: Hydrocolonic sonography is a valuable diagnostic tool with both high sensitivity and specificity for HD diagnosis, allowing morphological and vascular assessments of the colon, and correlates well with contrast enema. In the appropriate setting, hydrocolonic sonography may be an alternative screening method for HD in a large group of children with constipation. Key Points • Hydrocolonic sonography is a simple, well-tolerated diagnostic tool with both high sensitivity and specificity for HD diagnosis. • Hydrocolonic sonography allows morphological and vascular assessments of the colon, and correlates well with contrast enema. • Hydrocolonic sonography is a possible alternative modality for paediatric patients highly suggestive of HD.

Tripterygium and its plant extraction for systemic lupus erythematosus: A protocol for systematic review and meta analysis.

BACKGROUND: Systemic Lupus Erythematosus (SLE) is a diffuse connetive tissue disease, which is difficult to be conquered. However, the traditional Chinese medicine is significant in the treatment. And the Chinese medicine tripterygium and its plant extraction can help us to overcome this disease, to some extent. METHODS: The deadline should be from inception to February 2020 by computer from the databases: the Cochrane Library, Pubmed, Embase, Web of Science in English and the Chinese National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Literature Database and Chinese Science, Chinese Traditional Medicine Database, Chinese Science and Technology Periodical Database in Chinese. Included criteria are randomized controlled trials. The primary outcomes are the clinical symptoms, systemic lupus erythematosus disease activity index and quality of life questionnaire (the top 10 frequency). We will use RevMan 5.0 statistical software for data synthesis, sensitivity analysis, meta regression, subgroup analysis, and risk of bias assessment. The publish bias will be assessed by a funnel plot and the funnel plot symmetries will be evaluated by Begg and Egger tests. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence. RESULTS: This article will give a protocol for meta analysis which can make sure the efficacy and side effect of the tripterygium and its plant extraction for SLE. CONCLUSION: The efficacy and side effect of the tripterygium and its plant extraction for SLE will be evaluated. ETHICS AND DISSEMINATION: Without personal information involved, ethical approval and informed consent form is no need. The review will be submitted to a peer-reviewed journal prospectively to spread our findings. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42020176444.

Toxicology of tramadol following chronic exposure based on metabolomics of the cerebrum in mice.

Tramadol is an opioid used as an analgesic for treating moderate or severe pain. The long-term use of tramadol can induce several adverse effects. The toxicological mechanism of tramadol abuse is unclear. Metabolomics is a very useful method for investigating the toxicology of drug abuse. We investigated the impact of chronic tramadol administration on the cerebrum of mice, focusing on the metabolites after tramadol administration. The mice received 20 or 50 mg/kg body weight tramadol dissolved in physiological saline daily for 5 weeks via oral gavage. Compared with the control group, the low dose tramadol group showed seven potential biomarkers, including gamma-hydroxybutyric acid, succinate semialdehyde, and methylmalonic acid, which were either up- or down-regulated. Compared with the control group, the high dose tramadol group showed ten potential biomarkers, including gamma-hydroxybutyric acid, glutamine, and O-phosphorylethanolamine, which were either up- or down-regulated. The up-regulated gamma-hydroxybutyric acid and the down-regulated succinate semialdehyde revealed that the neurotransmitter system was disrupted after tramadol abuse. Compared with the low dose tramadol group, there were twenty-nine potential biomarkers in the high dose tramadol group, mainly related to the pentose phosphate pathway and glycerophospholipid metabolism. In conclusion, metabolomics in the tramadol abuse group demonstrated that long-term tramadol abuse can result in oxidative damage, inflammation, and disruption of the GABA neurotransmitter system, which will help to elucidate the toxicology of tramadol abuse.
