Published：2021-08-27 - Abstract：To compare balance ability between elderly individuals who practiced Tai-Chi-Chuan (TCC) for average 9.64 years and elderly individuals who did not practice TCC and its relationship with lower extremity muscle strength and ankle proprioception. Twenty-five elderly volunteers were divided into two groups according to their TCC practcing experience. Sixteen were TCC group and the other nine were control population. Subjects completed a static balance test and ankle proprioception test using a custom-designed evaluation system, and concentric and eccentric knee extensor and flexor muscle strength tests. Subjects stood on the plate form to measure the proprioception in functional standing position which was differed from the previous studies. Multiple linear regressions were also used to predict the important factor affecting balance. TCC group performed better than the control group in balance, proprioception, and muscle strength of lower extremity. The proprioception was the most important factor related to balance ability and it can be accounted for explaining 44% of variance in medial-lateral sway direction, and 53% of variance in antero-posterior sway direction. The proprioception may be a more important factor which affecting the balance ability. TCC training is recommended to the elders; as it can improve balance ability through better proprioception.Keywords：elders;Tai-Chi-Chuan;ankle proprioception;muscle strength;balance;predicted factor affecting the balance ability

Published：2021-08-27 - Abstract：To determine whether the nodule and eminence on the frenulum labii superioris, location of Yinjiao (DU28) according to the meridian theory, could be used to prognosticate the recurrence of patients with colorectal cancer. The data of 101 patients with colorectal cancer in Tianjin Medical University Cancer Institute and Hospital from May 2011 to November 2011 was analyzed. The photos of all patients’ frenulum labii superioris were taken. Nodule and eminence on frenulum labii superioris were the positive standard. Biopsy and pathological testing for the nodule were carried out on one patient with large nodule on frenulum labii superioris. Patients with positive frenulum labii superioris had a higher risk of recurrence and/or metastasis than patients with negative frenulum labii superioris. There were no significant differences in diagnosis of recurrence and/or metastasis between the status of frenulum labii superioris and the traditional diagnostic criteria (P =0.238). The Kappa was 0.606 (P <0.001). The sensitivity was 76.0% and the specificity was 85.4%. The pathological report demonstrated that the nodule on frenulum labii superioris was mucosal excrescence with normal structure. Nodule and eminence on frenulum labii superioris are potential diagnostic markers for metastatic colorectal cancer.Keywords：colorectal cancer;metastasis;recurrence;frenulum labii superioris

Published：2021-08-27 - Abstract：To observe the relaxant effect of Aike Mixture (艾可合剂, AKM) on isolated bladder and prostatic urethral smooth muscle of rabbits. The isolated bladder and prostatic urethral smooth muscle from male rabbits were placed in a Magnus bath and smooth muscle contraction was measured using a biological signal acquisition and analysis system. The effects of AKM in combination with methoxyamine, carbachol and CaCl2 on the contractile tension of muscle strips were determined by cumulative dosing. AKM dose-dependently reduced contractile tension of bladder trigone smooth muscle (r=0.831, P<0.05), reduced contractile wave amplitude (r=0.837, P<0.05) and decreased contractile frequency (r=−0.917, P<0.01). AKM significantly inhibited the increases in smooth muscle contraction induced by methoxyamine, carbachol and CaCl2. AKM dose-dependently inhibited the contraction of rabbit isolated bladder and prostatic urethral smooth muscle by antagonizing α1-adrenergic receptors and M-cholinergic receptors.Keywords：Aike Mixture;bladder smooth muscle;urethral smooth muscle;α1-adrenergic receptor;M-cholinergic receptor;Ca2+ channel

Published：2021-08-27 - Abstract：To evaluate whether garlicin can prevent reperfusion no-reflow in a catheter-based porcine model of acute myocardial infarction (AMI). Twenty-two male Chinese mini swines were randomized into 3 groups: sham-operation group (n=6), control group (n=8), and garlicin group (n=8). The distal part of left anterior descending coronary artery (LAD) in swines of the latter two groups was completely occluded by dilated balloon for 2 h and a successful AMI model was confirmed by coronary angiography (CAG) and electrocardiograph (ECG), which was then reperfused for 3 h. In the sham-operation group, balloon was placed in LAD without dilatation. Garlicin at a dosage of 1.88 mg/kg was injected 10 min before LAD occlusion until reperfusion for 1 h in the garlicin group. To assess serial cardiac function, hemodynamic data were examined by catheter method before AMI, 2 h after occlusion and 1, 2, and 3 h after reperfusion. Myocardial contrast echocardiography (MCE) and double staining with Evans blue and thioflavin-S were performed to evaluate myocardial no-reflow area (NRA) and risk area (RA). Left ventricular systolic pressure and left ventricular end-diastolic pressure significantly improved in the garlicin group after reperfusion compared with the control group P<0.05) and 2 h after AMI (P<0.05). MCE showed garlicin decreased reperfusion NRA after AMI compared with the control group (P <0.05). In double staining, NRA/RA in the garlicin group was 18.78%, significantly lower than that of the control group (49.84%, P<0.01). Garlicin has a preventive effect on the porcine model of myocardial infarction reperfusion no-reflow by improving hemodynamics and decreasing NRA.Keywords：garlicin;reperfusion;no-reflow;myocardial infarction;prevention;Allium sativum

Published：2021-08-27 - Abstract：To evaluate the effects of the ethanol extract isolated from Weiqi Decoction (胃祺饮, WQD-EE) on AGS cell proliferation and apoptosis. By using high-performance liquid chromatography with ultraviolet detectors (HPLC-UV) assay and MTT method, the main compounds in WQD-EE and cell viability were detected. And cell cycle distributions were determined by flow cytometry with propidium iodine (PI) staining while apoptosis was detected by flow cytometry with annexin V/PI double staining. Finally, caspase-3 activities were measured by colorimetric method and protein expression was determined by Western blotting. HPLC analysis showed that naringin (35.92 μg/mg), nobiletin (21.98 μg/mg), neohesperidin (17.98 μg/mg) and tangeretin (0.756 μg/mg) may be the main compounds in WQD-EE. WQD-EE not only inhibited AGS and MCF 7 cell proliferation in a dose-dependent manner, but also blocked cell cycle progression at G2/M stage as well as inducing cell apoptosis at concentrations triggering significant inhibition of proliferation and cell cycle arrest in AGS cells. While at 0.5 mg/mL, WQD-EE significantly increased caspase-3 activity by 2.75 and 7.47 times at 24 h and 48 h, respectively. Moreover, WQD-EE in one hand reduced protein expressions of p53 and cyclin B1, and in other hand enhanced protein expressions of cytochrome c and Bax. Protein levels of Bcl-2, Fas L and Fas were not significantly affected by WQD-EE. WQD-EE inhibits AGS cell proliferation through G2/M arrest due to down-regulation of cyclin B1 protein expression, and promotes apoptosis by caspase-3 and mitochondria-dependent pathways, but not by p53-dependent pathway.Keywords：Weiqi Decoction;proliferation;apoptosis;AGS cells;Chinese Medicine

Published：2021-08-27 - Abstract：To investigate the effect of Ganfukang (肝复康, GFK) on connective tissue growth factor (CTGF) and focal adhesion kinase (FAK)/protein kinase B (PKB or Akt) signal pathway in a hepatic fibrosis rat model and to explore the underlying therapeutic molecular mechanisms of GFK. Fifty SD rats were randomly divided into five groups as follows: the control group, the model group (repeated subcutaneous injection of CCl4), and the three GFK treatment groups (31.25, 312.5, and 3125 mg/kg, intragastric administration). Reverse transcriptase-polymerase chain reaction (RT-PCR), Western blotting, and immunohistochemistry were used to examine the expression of CTGF, integrin α5, integrin β1, FAK/Akt signal pathway, cyclinD1, and collagen in the different-treated rats. GFK attenuated the up-regulation of CTGF, integrin α5, and integrin β1 in hepatic fibrosis rats and suppressed both the phosphorylation of FAK and the phosphorylation of Akt simultaneously (P<0.01). At the same time, the expression of cyclinD1, collagen I, and collagen III was decreased by GFK significantly (P<0.01). CTGF and FAK/Akt signal pathway were activated in the CCl4-induced hepatic fibrosis rats, which contribute to increased expression of cyclinD1 and collagen genes. The mechanisms of the anti-fibrosis activity of GFK may be due to its effects against CTGF and FAk/Akt signal pathway.Keywords：connective tissue growth factor;Ganfukang;Hepatic Fibrosis;FAK/Akt signal pathway

Published：2021-08-27 - Abstract：To observe the effects of different doses of Wenxiao Decoction (稳消方) on the expression of interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), and monocyte chemoattractant protein-1 (MCP-1) in experimental atherosclerotic rabbits and to explore the mechanism by which it alleviates atherosclerosis. Sixty New Zealand rabbits were randomly divided into six groups: a blank group, a model group, a Simvastatin group, and high-, medium-, and low-dosage Wenxiao Decoction groups. Except for those in the blank group, all rabbits were fed with a high-cholesterol diet. Carotid atherosclerosis was established by balloon-induced carotid artery endothelium injury in conjunction with the high-cholesterol diet. After 8 weeks, all animals were euthanized to evaluate levels of IL-6 and ICAM-1 expressions (by enzyme linked immunosorbent assay) and of MCP-1 (by immunohistochemistry staining). The expressions of IL-6, ICAM-1, and MCP-1 were significantly increased in all groups except the blank group (P<0.05). However, the rabbits in the Wenxiao Decoction groups and the Simvastatin group showed significantly lower levels of IL-6, ICAM-1, and MCP-1 expression than those in the model group (P<0.05). The expressions of IL-6, ICAM-1, and MCP-1 in the highdosage Wenxiao Decoction group and the Simvastatin group were lower than those in the low-dosage Wenxiao Decoction group (P<0.05). The expression of MCP-1 in medium-dosage Wenxiao Decoction group was lower than that in the low-dosage group (P<0.05). High, medium, and low doses of Wenxiao Decoction can inhibit the expressions of IL-6, ICAM-1, and MCP-1, which may prevent and stabilize atherosclerotic plaques. There may be a direct relationship between dosage and therapeutic efficacy of Wenxiao Decoction.Keywords：Wenxiao Decoction;atherosclerosis;interleukin-6;intercellular adhesion molecular-1;monocyte chemoattractant protein-1;Chinese Medicine

Published：2021-08-27 - Abstract：To investigate whether total triterpene acids (TTAs), isolated from Cornus Fructus, attenuates renal function by reducing oxidative stress and down-regulating the expression of transforming growth factor β1 (TGF-β1). Diabetes was induced by an injection of streptozotocin (40 mg/kg intravenously). Thirty rats were randomly divided into three groups: control group, diabetic model group and TTAs treatment group (50 mg/kg, intragastrically) administrated for 8 weeks from 5th to 12th week. All rats were anaesthetized and then were killed to remove kidneys. The renal function and redox enzyme system parameters were tested. Glomerular morphology was observed by a light microscopy. Immunohistochemistry and Western blot assays were employed to determine the protein levels of TGF-β1. TTAs attenuated the levels of urinary protein, serum creatinine and blood urea nitrogen, although it did not significantly reduce the level of glucose. In addition, TTAs decreased the malondialdehyde while increased superoxide dismutase, catalase and glutathione peroxide activities in diabetic rats. The renal pathological changes in TTAs treatment group were ameliorated. Furthermore, TTAs also ameliorated the expression of TGF-β1. TTAs improved renal function via reducing oxidative stress and down-regulation the expression of TGF-β1 in diabetic rats.Keywords：total triterpene acids;diabetic nephropathy;oxidative stress;transforming growth factor β1

Published：2021-08-27 - Abstract：To investigate the effect of Modified Zhuye Shigao Decoction (加味竹叶石膏汤, MZSD) and its components on preventing radiation esophagitis of rats. One hundred Wistar rats were randomly divided into 5 groups, including the control group, radiation model group, MZSD group, Zhuye Shigao Decoction (竹叶石膏汤, ZSD) group, and added ingredients group, 20 rats in each group. The model of radiation esophagitis of rat was established by once local radiation of 40 Gy (330 Mu/min) with a high energy linear accelerator. The administration of Chinese medicine was continued for 14 days from 7 days before radiation application in the three treatment groups. On the 7th and 14th day, the serum was isolated and the levels of inflammatory cytokines tumor necrosis factor (TNF-α), interleukin 1β (IL-1β) and IL-8 were tested. The pathological slices of esophagus were obtained, and the pathological changes were observed. During the whole process, weight and food intake were recorded each day. On the 7th day after radiation, the esophagus of rats in the MZSD group was almost intact, and the pathological injury score was significantly lower than that of the radiation model group, ZSD group and added ingredients group (P<0.01). Compared with the control group, the body weight and food intake of rats in the radiation model group were significantly decreased, and the levels of TNF-α, IL-1β and IL-8 were significantly increased (P<0.05 or P<0.01), while the MZSD group showed a significant increase in body weight and food intake, and a significant decrease in the levels of TNF-α, IL-1β and IL-8 compared with the radiation model group, ZSD group and added ingredients group (P <0.05 or P<0.01). MZSD prevents the development of radiation esophagitis probably by inhibiting the generation and release of the inflammatory cytokines TNF-α, IL-1β and IL-8.Keywords：Modified Zhuye Shigao Decoction;Chinese Medicine;radiation esophagitis;inflammatory cytokines

Published：2021-08-27 - Abstract：To explore natural herbs to maintain the bactericidal activity of hydrogen peroxide (H). Eighteen extracts of Chinese herbs were prepared complying with the standard protocol. Each of the solutions was then mixed with 1% H2O2. The mixtures were handled with two approaches: autoclaved daily for one, two or three times; stored at room temperature from one through five years. Then the bactericidal activity were evaluated by assaying the minimal bactericidal concentration (MBC) and minimal inhibitory concentration (MIC) against Gram positive (Staphylococcus aureus, ATCC25923) and Gram negative (Escherichia coli, ATCC12421) bacteria. While mixed with 1% H2O2, 10 out of 18 kinds of assessed Chinese herbs displayed MBC values at 1:12800 or higher after three times of autoclaving, and 8 of them preserved such level of MBC value after stored at room temperature for three years. Some Chinese herbs, i.e. R. Scutellariae, R. Coptidis, R. Bupleuri, H. Epimedii, C. Phelledendri and F. Chrysanthemi, can significantly maintain the bactericidal activity of diluted H2O2 Certain Chinese herbs can effectively stabilize the bactericidal activity of H2O2 undergoing autoclave or long-term storage. This paper reported a brandnew pharmaceutical function of Chinese herbs and provided experimental data for the potential enhancement of H2O2 usage while its stability level is promoted.Keywords：hydrogen peroxide;bactericidal activity;minimal bactericidal concentration;minimal inhibitory concentration;Chinese herbs
