[Changes of inherent immune response and acquired immune response in the tung tissue and the intestinal tissue of ulcerative colitis rats and the intervention of Chinese compound: an experimental research].

OBJECTIVE: To explore Chinese medical theory of Fei and Dachang being interior-exteriorly correlated by observing changes of inherent immune response and acquired immune response in the lung tissue and the intestinal tissue of ulcerative colitis (UC) model rats and the intervention of Chinese compounds (CM). METHODS: Seventy rats were randomly divided into 5 groups, i.e., the normal control group (n = 10), the model group (n = 15), the treatment 1 group (n = 15, treated from Fei), the treatment 2 group (n = 15, treated from the intestine), and the Western medicine (WM) group [n = 15, treated with Sulfasalazine (SASP). Except those in the normal control group, the UC rat model was prepared by allergizing colon mucosa combined with TNBS-alcohol (50%) enema, and then intervened by medication (treated with CM complex prescription of treatment from lung, CM complex prescription of treatment from intestine, and SASP). After intragastric administration for 4 weeks, rats were sacrificed and samples taken. The expression of tumor necrosis factor α (TNF-α) and IL-8 contents in the lung tissue, the intestinal tissue, and the serum were detected by radioimmunoassay. Serum MedCAM-1 contents were detected using ELISA. Changes of the expression of Toll-like receptor 4 (TLR4), nuclear factor κB (NF-κB), neutrophil migration inhibition factor (MIF), mucosal addressin cell adhesion molecule-1 (MadCAM-1) mRNA in the lung tissue and the intestinal tissue were detected by real time PCR. RESULTS: Compared with the normal control group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mR- NA, and MadCAM-1 mRNA obviously increased in the model group (P < 0.01). Compared with the model group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mRNA, and MadCAM-1 mRNA obviously decreased in the treatment 1 and 2 groups (P < 0.01). The expression of MadCAM-1 mRNA in the intestinal tissue was obviously higher in the model group than in the normal control group (P < 0.01), while the expressions of TNF-α and NF-κB mRNA was obviously lower in the model group than in the normal control group (P < 0.05, P < 0.01). Compared with the model group, the expression of MadCAM-1 mRNA all significantly deceased in each treatment group (P < 0.05, P < 0.01). Serum TNF-α contents were higher in the model group than in the normal control group (P < 0.05). Compared with the model group, serum TNF-α contents could be lowered in the treatment 1 and 2 groups (P < 0.05, P < 0.01). CONCLUSIONS: The main mechanisms of the intestinal injury in this UC model might be related with activation of acquired immune response, accompanied with lowered functions of inherent immune response. The main mechanisms of the lung injury in this UC model might be related acquired immune response and inherent immune response. Treatment from Fei and treatment from Dachang both could obviously improve the immunodissonance of Fei and Dachang, indicating the special relation between the lung tissue and the intestinal tissue, thus providing experimental evidence for Chinese medical theory of Fei and Dachang being interior-exteriorly correlated.

[Effects of Chinese herbal medicines Shengmai injection and Xuesaitong injection on ventricular fibrillation threshold and connexin 43 expression in rats with myocardial infarction].

OBJECTIVE: To explore the effects of Shengmai injection and Xuesaitong injection, compound Chinese herbal medicines for replenishing qi and activating blood, on ventricular fibrillation threshold, heart structure and connexin 43 (Cx43) expression in rats with myocardial infarction (MI). METHODS: One hundred male SD rats were randomly divided into sham operation group, model group, Yiqi Huoxue (YQHX) group (Shengmai injection plus Xuesaitong injection) and captopril group. MI model of rats was established by ligating left anterior descending coronary artery, and rats in sham operation group were prepared in the same way except for the ligation of coronary artery. Rats were treated with corresponding drugs for 1 month from next day after modeling. After treatment ventricular fibrillation threshold was detected, and heart weight index, left ventricular internal diameter and percentage of myocardial infarction were measured. Expression of Cx43 mRNA in myocardium was detected by real-time fluorescent quantitative polymerase chain reaction, and expression of Cx43 protein was observed by immunohistochemical method. RESULTS: Compared with the sham operation group, ventricular fibrillation threshold decreased significantly, heart weight index and left ventricular internal diameter increased, while expressions of Cx43 mRNA and protein decreased remarkably in the model group (P<0.01). Compared with the model group, ventricular fibrillation threshold was increased significantly, heart weight index, left ventricular internal diameter and percentage of myocardial infarction were decreased significantly in the YQHX group and captopril group (P<0.05 or P<0.01). When it comes to expression of Cx43, both Cx43 mRNA and protein expressions were increased remarkably in the YQHX group compared with the model group (P<0.05 or P<0.01), while only density mean and integral optical density of Cx43 protein expression were increased significantly in the captopril group (P<0.05). The enhancements on Cx43 mRNA and positive area sum of Cx43 protein induced by YQHX drugs were stronger than those induced by captopril (P<0.05). CONCLUSION: Shengmai injection and Xuesaitong injection have beneficial effects on ventricular fibrillation threshold in rats with MI. The mechanism is related with improving heart structure and reducing Cx43 expression after MI.

Hypoglycaemic and hypolipidaemic effects of emodin and its effect on L-type calcium channels in dyslipidaemic-diabetic rats.

1. The aim of the present study was to evaluate the hypoglycaemic and hypolipidaemic effects of 20, 40 and 80 mg/kg per day emodin and its potential effects on L-type calcium channels in dyslipidaemic-diabetic rats. 2. Dyslipidaemic-diabetic rats were induced by a single intraperitoneal injection of streptozotocin (55 mg/kg) after intragastric administration of a high-fat diet for 2 weeks. 3. Daily administration of emodin for 2 weeks resulted in a significant dose-dependent reductions in blood glucose, serum total cholesterol, triglycerides, free fatty acids and malonaldehyde (P < 0.05) in dyslipidaemic-diabetic rats compared with vehicle-treated dyslipidaemic-diabetic rats. In addition, emodin caused dose-dependent increases in plasma superoxide dismutase activity in dyslipidaemic-diabetic rats (P < 0.05). Immunofluorescent staining and reverse transcription-polymerase chain reaction showed that the expression of L-type calcium channels in the pancreas and heart was restored, to different extents, by the three doses of emodin treatment. 4. The results of the present study suggest that emodin has antidiabetic and lipid-modulating effects that involve, in part, upregulation of L-type calcium channel expression in the pancreas and heart in dyslipidaemic-diabetic rats.

[Treatment of beta-thalassemia with Bushen Yisui therapy: a randomized controlled trial].

OBJECTIVE: To investigate the efficacy and safety of Yisui Shengxue Granule (YSSXG), a compound traditional Chinese herbal medicine, in treating beta-thalassemia. METHODS: A randomized single-blinded trial was designed. Sixty patients with beta-thalassemia were divided into two groups: 30 patients in YSSXG-treated group and 30 in placebo parallel-control group. The patients in the two groups were assigned to receive either YSSXG or placebo for three months. The patients' symptoms and their blood indexes such as hemoglobin (Hb), red blood cell (RBC), reticulocytes (Ret) and fetal hemoglobin (HBF) were examined before and after the treatment. Meanwhile, the liver and spleen were examined with B-mode ultrasound. RESULTS: In the YSSXG-treated group, the blood indexes (Hb, RBC, Ret and HBF) and the symptoms of the patients were improved after three-month treatment, with statistical significance compared to those before treatment (P<0.01); hepatauxe and splenomegaly were also relieved (P<0.05) and no adverse reactions were monitored. In the placebo parallel-control group, no significant improvement of the blood indexes and symptoms, as well as the hepatauxe and splenomegaly had been found (P>0.05). CONCLUSION: YSSXG demonstrates obvious clinical efficacy and no adverse reactions in treating beta-thalassemia.

Effects of Chinese herbal formula Erxian decoction for treating osteoporosis: a systematic review.

PURPOSE: The aim is to systematically assess the effectiveness and safety of Chinese herbal formula Erxian decoction (EXD) for treating osteoporosis. MATERIALS AND METHODS: Six databases were searched from inception through September 17, 2016, without language restriction. All randomized controlled trials of EXD for osteoporosis were included. One or more outcome measures including fracture, change in bone mineral density (BMD), pain symptom improvement, bone biochemical markers, quality of life, adverse event or adverse drug reaction were evaluated. Study selection, data extraction, quality assessment, and data analyses were conducted according to Cochrane standards. RESULTS: Eight trials including 644 patients investigated the effects of EXD in the treatment of osteoporosis. The methodological quality of the included trials was generally low. The meta-analysis from two trials showed favorable effects of EXD in improving BMD of lumbar spine (mean difference [MD]: 0.05 [0.03, 0.06]; I2=0%; P<0.00001) and BMD of femoral great trochanter (MD: 0.06 [0.02, 0.10]; I2=59%; P=0.005) compared with caltrate tablets. The other meta-analysis from two trials showed beneficial effects of EXD plus caltrate tablets and calcitriol in improving BMD of femoral neck (MD: 0.04 [0.00, 0.09]; I2=56%; P=0.04), the level of calcium (MD: 0.20 [0.15, 0.24]; I2=0%; P<0.00001), and phosphorus (MD: -0.28 [-0.39, -0.17]; I2=68%; P<0.00001) compared with caltrate tablets and calcitriol alone. The adverse drug reactions of EXD were mainly slight gastrointestinal symptoms. CONCLUSION: The study provides suggestive evidence of the superiority of EXD monotherapy or combination therapy over basic supplements for treating osteoporosis. However, the evidence remains weak. More rigorously designed and measured, randomized double-blind, placebo-controlled trials with larger sample size are needed to verify the current conclusions.

EFFECT OF YISHENJIANPI RECIPE ON SEMEN QUALITY AND SPERM MITOCHONDRIA IN MICE WITH OLIGOASTHENOZOOSPERMIA INDUCED BY TRIPTERYGIUM GLYCOSIDES.

BACKGROUND: Kidney tonifying - spleen strengthening method being one of the modalities for treatment of astheno-oligozoospermia is currently commonly used in the clinical setting. To investigate the mechanism of YiShenJianPi (YSJP) Recipe, used in Traditional Chinese Medicine to benefit "the kidney" and strengthen "the spleen". MATERIALS AND METHODS: Oligoasthenozoospermia, male BALB/c mice were randomly divided into normal control, disease model, positive control, low-dosage and high-dosage groups. Oligoasthenozoospermia was induced by tripterygium glucosides intragastric administration before treatment started. Through using computer-aided sperm analysis to test the changes in sperm quality, utilizing flow cytometry to test the percentage of sperm with normal mitochondrial transmembrane potential (JC-1 + %), utilizing X-ray microscopy to observe epididymal sperm ultra-microstructure placing special emphasis and photographing the differences in mitochondria of the flagellum region. RESULTS: Compared with DM, sperm quality of the treated mice was significantly better (P<0.05, respectively). Compared with PC, the LD group had significantly better quality sperms, while the parameters in the HD group were numerically better. Compared with NC, all other groups had significantly lower percentage of sperms with normal mitochondrial membrane potential. In PC, LD and HD groups, the percentage of sperms with normal mitochondrial membrane potential was significantly higher than that of D. The 9+9+2 mitochondrial sheath structure was complete in NC but damaged in DM. In the treatment groups, this structure was fairly clear. CONCLUSION: YSJP improved semen quality with oligoasthenozoospermia by improving sperm mitochondrial membrane potential and restoring sperm mitochondrial ultrastructure.

[Effects of yisui shengxue granules on expressions of alpha-hemoglobin stabilizing protein and erythroid transcription factor GATA-1 mRNAs in bone marrow of patients with beta-thalassemia].

OBJECTIVE: To evaluate the effects of Yisui Shengxue Granules on expressions of alpha-hemoglobin stabilizing protein (AHSP) and erythroid transcription factor GATA-1 mRNAs in bone marrow of patients with beta-thalassemia, and to explore its possible molecular mechanism. METHODS: Twelve patients with beta-thalassemia intermedia were treated with Yisui Shengxue Granules for three months. The blood indexes including hemoglobin (Hb), RBC, fetal hemoglobin (HbF) and reticulated corpuscles (Ret) were examined before and after treatment. Total RNA was extracted from bone marrow karyocyte in 8 patients selected from these 12 patients before and after treatment, and the expression levels of the AHSP and GATA-1 mRNAs were measured by real-time PCR. RESULTS: Yisui Shengxue Granules could not only obviously improve the clinical symptoms of patients with beta-thalassemia intermedia, but also obviously increased the contents of Hb, RBC, HbF and Ret (P<0.05, or P<0.01). The expression levels of AHSP and GATA-1 mRNAs also significantly increased after treatment as compared with those before treatment (P<0.05, or P<0.01). CONCLUSION: The results revealed that one of the possible molecular mechanism of the effects caused by Yisui Shengxue Granules is that it can up-regulate the expression levels of AHSP and erythroid transcription factor GATA-1 mRNAs, enhance the protein synthesis of AHSP which can bind the relative excess free alpha-globin, prevent the formation of alpha -globin-cytotoxic precipitates in red blood cells and decrease the hemolysis.

[Effect of yisui shengxue granule on gene expression in children with beta-thalassemia].

OBJECTIVE: To investigate the mechanism of yisui shengxue granule (YSG) in children with betathalassemia. METHODS: The changes of hemoglobin (Hb), red blood cells (RBC), reticulocyte (Ret) and fetal hemoglobin (HbF) of 20 children with beta-thalassemia were measured before and after treatment. The effect of YSG on gene expression in myelo-karyocytes in 3 selected children treated effectively by YSG was determined by using DDRT-PCR. RESULTS: The hematologic parameters were significantly enhanced and the ferritin gene expression declined after treatment respectively, as compared with those before treatment, the difference were significant (P < 0.01 or P < 0.05). CONCLUSION: YSG could improve the clinical symptoms of children with beta-thalassemia. One of its therapeutic mechanisms may be its action in decreasing ferritin gene expression so as to effectively relieve the accumulation of iron in body.
