Tonghua Liyan granules in the treatment of Laryngopharyngeal reflux disease with stagnation of phlegm and qi syndrome: a randomized, double-blind, placebo-controlled study.

Background: Laryngopharyngeal reflux disease (LPRD) is an extraesophageal syndromic manifestation of gastroesophageal reflux disease (GERD). Despite the increasing incidence of and concern about LPRD, treatment with proton pump inhibitors (PPIs) is unsatisfactory. Here, LPRD was treated with Tonghua Liyan (THLY) granules in combination with PPIs to evaluate treatment efficacy and possible adverse reactions. Methods: Seventy-six LPRD patients with stagnation of phlegm and qi syndrome (SPQS) were randomly divided into an experimental group and a control group. The experimental group received THLY granules combined with rabeprazole capsules. The control group received THLY granule placebo combined with rabeprazole capsules. A parallel, randomized, double-blind, placebo-controlled clinical trial was conducted with these two groups. The treatment cycle was 8 weeks. The reflux symptom index (RSI), clinical symptom score, salivary pepsin content, reflux finding score (RFS) and gastroesophageal reflux disease questionnaire (GerdQ) were used to evaluate clinical efficacy. The final efficacy rate was evaluated according to the RSI and clinical symptom score. Results: Compared with those at baseline, all the indicators in the experimental group and control group significantly improved (p < 0.01). In terms of the RSI, clinical symptom score, and RFS, the experimental group had a higher degree of improvement (p < 0.05), and the overall efficacy rate was higher (p < 0.05). In terms of the salivary pepsin concentration and GerdQ, there was no significant difference between the test group and the control group (p > 0.05). Both groups of safety indicators showed no abnormalities and did not cause any allergic reactions in the body. Conclusion: Compared with PPIs alone, THLY granules combined with PPIs are more effective in the treatment of LPRD patients with SPQS in terms of symptoms and signs. This combination treatment, because of its higher clinical efficacy and lack of obvious adverse reactions, is worthy of clinical promotion and further in-depth study.

Da-Cheng-Qi decoction improves severe acute pancreatitis-associated acute lung injury by interfering with intestinal lymphatic pathway and reducing HMGB1-induced inflammatory response in rats.

CONTEXT: Da-Cheng-Qi Decoction (DCQD) has a significant effect on Severe Acute Pancreatitis-Associated Acute Lung Injury (SAP-ALI). OBJECTIVE: To explore the mechanism of DCQD in the treatment of SAP-ALI based on intestinal barrier function and intestinal lymphatic pathway. MATERIALS AND METHODS: Forty-five Sprague-Dawley rats were divided into three groups: sham operation, model, and DCQD. The SAP model was induced by a retrograde infusion of 5.0% sodium taurocholate solution (1 mg/kg) at a constant rate of 12 mL/h using an infusion pump into the bile-pancreatic duct. Sham operation and model group were given 0.9% normal saline, while DCQD group was given DCQD (5.99 g/kg/d) by gavage 1 h before operation and 1, 11 and 23 h after operation. The levels of HMGB1, RAGE, TNF-α, IL-6, ICAM-1, d-LA, DAO in blood and MPO in lung were detected using ELISA. The expression of HMGB1, RAGE, NF-κB p65 in mesenteric lymph nodes and lung were determined. RESULTS: Compared with SAP group, DCQD significantly reduced the histopathological scoring of pancreatic tissue (SAP, 2.80 ± 0.42; DCQD, 2.58 ± 0.52), intestine (SAP, 3.30 ± 0.68; DCQD, 2.50 ± 0.80) and lung (SAP, 3.30 ± 0.68; DCQD, 2.42 ± 0.52). DCQD reduced serum HMGB1 level (SAP, 134.09 ± 19.79; DCQD, 88.05 ± 9.19), RAGE level (SAP, 5.05 ± 1.44; DCQD, 2.13 ± 0.54). WB and RT-PCR showed HMGB1-RAGE pathway was inhibited by DCQD (p < 0.01). DISCUSSION AND CONCLUSIONS: DCQD improves SAP-ALI in rats by interfering with intestinal lymphatic pathway and reducing HMGB1-induced inflammatory response.

Compared with the standard treatment group, the levels of WBC, ALT, CA, hemodiastase, lipase, TG, and other factors in the TCM treatment group decreased, whereas the levels of DB, SCR, cholesterol, K+, and other factors increased. The differences were statistically significant (P < 0.05). Conclusion: Chaihu Shugan powder combined with Zu San Li acupoint stimulation can reduce the clinical manifestations of liver and qi stagnation syndromes of acute pancreatitis, protect the intestinal barrier function, prevent the tendency of severe illness and improve the prognosis.

Study on the medication rule of traditional Chinese medicine in the treatment of acute pancreatitis based on machine learning technology.

BACKGROUND: To analyze the rule of traditional Chinese medicine in the treatment of acute pancreatitis (AP). METHODS: Using machine learning technology and artificial intelligence, we collected 516 traditional Chinese medicine compounds for treating AP in the recent past 20 years, and analyzed the application of Chinese medicine in the field of AP. The data set was established by the ingredients of each prescription and its corresponding effectiveness. 90% of the data was divided into the training set, and the remaining 10% of the data was used as the test set. We employed random forest method to build a model to predict the efficacy of the prescriptions in the treatment of AP. The R-squared score and mean absolute error was used to evaluate the model's performance. RESULTS: The most frequently used drugs were rhubarb, Radix Bupleuri, Fructus Aurantii Immaturus, and Mirabilite. Rhubarb and Rhizoma Corydalis had the greatest curative effect. The random forest model that fit all data showed that its R-squared score reached 0.8021. And the results predicted on the test set showed that the R-squared score reached 0.7318. CONCLUSIONS: Soothing the liver, promoting qi, clearing heat, removing obstructions of organs, activating blood, and resolving stagnation are the treatment methods for AP.

Neolinulicin A and B from Inula japonica and their anti-inflammatory activities.

A phytochemical study performed on Inula japonica led to isolation of a new 1,10-seco-sesquiterpene dimer Neolinulicin A (1) and 1,10-seco-sesquiterpene Neolinulicin B (2), together with nine known sesquiterpenes (3-11). Among them, Neolinulicin A (1), which has a new carbon skeleton, was a Diels-Alder [4 + 2] adduct of two sesquiterpene moieties. Their structures were established by extensive spectroscopic analysis. All of the isolated compounds showed inhibition of NO production in RAW 264.7 macrophages. The findings might supply information for the future design of anti-inflammatory agents from I. japonica.

Effects of Shugan Hewei Granule on Depressive Behavior and Protein Expression Related to Visceral Sensitivity in a Rat Model of Nonerosive Reflux Disease.

OBJECTIVE: To explore the effect of Shugan Hewei Granule (SGHWG) and to provide the experimental basis for its clinical application. METHODS: 40 healthy male Wistar rats were divided into 5 groups, with 8 rats in each group, including control group, model group, normal saline (NS) group, SGHWG group, and Rabeprazole group. The control group was not treated. The model group was treated with fructose intake and mental stress to be the model of NERD. The other groups were treated as the model group and then gavaged with the corresponding drugs. The pH value of lower third of esophagus, immobile time in tail suspension test, CRF protein expression in both hypothalamus and anterior cingulate cortex (ACC), and SP protein in esophageal mucosa in lower third of esophagus detected by immunofluorescence and NMDAR1 protein expression in spinal cord detected by immunohistochemistry of each group were compared. RESULTS: The pH values of both the SGHWG group and the Rabeprazole group were higher than that of the model group (P<0.01), but the Rabeprazole group increased more obviously. The immobile time of the SGHWG group was shorter than that of the model group (P<0.01) and the Rabeprazole group (P<0.05). The expression of the CRF in the hypothalamus and ACC, NMDAR1 in the spinal cord, and SP in the esophageal mucosa in lower third of esophagus of the SGHWG group decreased significantly, compared with the model group (P<0.01), and was obviously lower than that in the Rabeprazole group (P<0.05). CONCLUSIONS: This study provided an evidence that SGHW formula was inferior to Rabeprazole in acid inhibition, but it might reduce the expression of CRF protein of hypothalamus and ACC, lower the levels of NMDAR1 in spinal dorsal horn and SP in esophageal mucosa in lower third of esophagus, and regulate depressive behavior simultaneously, related to the improvement of visceral hypersensitivity in rat model of NERD.

Is Huachansu Beneficial in Treating Advanced Non-Small-Cell Lung Cancer? Evidence from a Meta-Analysis of Its Efficacy Combined with Chemotherapy.

Background. Huachansu, the sterilized water extract of Bufo bufo gargarizans toad skin, is used in China to alleviate the side-effects and enhance the therapeutic effect of chemotherapy in advanced non-small-cell lung cancer (NSCLC). We conducted a meta-analysis to assess Huachansu's efficacy. Methods. We extensively searched electronic databases (CENTRAL, EMBASE, MEDLINE, CBM, Cochrane Library, CNKI, CEBM, WFDP, CSCD, CSTD, and IPA) for randomized controlled trials containing Huachansu plus chemotherapy as the test group and chemotherapy as the control group. Seventeen trials were selected based on the selection criteria. The pooled relative ratio (RR) of indicators with 95% confidence interval (95% CI) was calculated for efficacy evaluation. Results. The meta-analysis demonstrated a statistically significant improvement in objective tumor response, one-year survival, Karnofsky performance status, pain relief, and alleviation of severe side-effects (nausea and vomiting, leukocytopenia) in the test group as compared to the control group, but no significant difference in thrombocytopenia. Conclusions. This study demonstrated the efficacy of Huachansu combined with chemotherapy in the treatment of advanced NSCLC. However, limitations exist and high-quality trials are needed for further verification.

[Clinical characteristics of patients with reflux esophagitis exhibiting gallbladder heat attacking the stomach or stagnant heat of the liver and stomach syndrome].

OBJECTIVE: To compare the characteristics of the traditional Chinese medicine (TCM) syndromes of gallbladder heat attacking the stomach and stagnant heat of the liver and stomach in patients with reflux esophagitis (RE), in terms of clinical symptoms, combination of gallbladder conditions, esophageal mucosal inflammation, gastric bile reflux under endoscopy and helicobacter pylori (HP) infection. METHODS: Patients with RE were enrolled from Yueyang Hospital of Integrated Traditional Chinese and Western Medicine from June 2007 to December 2009 and patients exhibiting the syndrome of gallbladder heat attacking the stomach or stagnant heat of the liver and stomach were collected. The patients were requested to complete clinical questionnaires. The general data, characteristics of clinical symptoms, combination of gallbladder conditions, esophageal mucosal inflammation, gastric bile reflux under endoscopy and HP infection of the two patterns were compared. RESULTS: The average age of the selected patients with gallbladder heat attacking the stomach was older than that of the patients with stagnant heat of the liver and stomach (P<0.01) and the accompanying clinical signs and symptoms were more severe (P<0.01). The incidence of gallbladder diseases in patients with gallbladder heat attacking the stomach was higher than that of the patients with stagnant heat of the liver and stomach (P<0.01). The extent of the esophageal mucosal inflammation under endoscopy as well as the gastric bile reflux and the incidence of HP infection was also more severe (P<0.01). CONCLUSION: There are significant differences in several regards between the syndromes of gallbladder heat attacking the stomach and stagnant heat of the liver and stomach in patients with RE. These characteristics may provide sound evidence for differentiation of signs and symptoms for this disease.
