Antitumor effect and mechanism of Gecko on human esophageal carcinoma cell lines in vitro and xenografted sarcoma 180 in Kunming mice

AIM: To investigate the anti-tumor effect of Chinese medicine Gecko on human esophageal carcinoma cell lines and xenografted sarcoma 180 in Kunming mice and its mechanism. METHODS: The serum pharmacological method was used in vitro . The growth rates of the human esophageal carcinoma cells (EC9706 or EC1) were measured by a modifi ed 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The transplanted tumor model of the mouse S180 sarcoma was established. Fifty mice were randomly divided into fi ve groups (n = 10). Three Gecko groups were treated respectively with oral administration of Gecko powder at a daily dose of 13.5 g/kg, 9 g/kg, and 4.5 g/kg. The negative group (NS group) was treated with oral administration of an equal volume of saline and the positive group (CTX group) was treated with 100 mg/kg Cytoxan by intraperitoneal injection at the fi rst day. After 2 wk of treatment, the anti-tumor activity was evaluated by tumor tissue weighing. The impact on immune organ was detected based on the thymus index, spleen index, phagocytic rate and phagocytic index. The protein expression of vascular endothelingrowth factor (VEGF) and basic fibroblast growth factor (bFGF) were detected by immunohistochemistry. The cell apoptotic rate was detected by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay. RESULTS: The A value in each group treated with Gecko after 72 h was reduced signif icantly in EC9706 and in EC1. The tumor weight in each group of Gecko was decreased signifi cantly (1.087 ± 0.249 vs 2.167 ± 0.592; 1.021 ± 0.288 vs 2.167 ± 0.592; 1.234 ± 0.331 vs 2.167 ± 0.592; P < 0.01, respectively). However, the thymus index and Spleen index of mice in Gecko groups had no significant difference compared with the NS group. The immunoreactive score of VEGF and bFGF protein expression of each Gecko group by immunohistochemical staining were lowered signifi cantly. The apoptosis index (AI) of each group was increased progressively with increase of dose of Gecko by TUNEL. CONCLUSION: Gecko has anti-tumor effects in vitro and in vivo; induction of tumor cell apoptosis and the down-regulation of protein expression of VEGF and bFGF may be contributed to anti-tumor effects of Gecko.

Acupuncture therapy for experimental stomach ulcer and c-Fos expression in rats

AIM: To determine the role of acupuncture therapy in treating experimental gastric ulcer in rats.METHODS: Twenty-eight adult male Sprague-Dawley rats were randomly divided into four groups (pre-acupuncture group; acupuncture group; paradistance-acupuncture group;and control group), and pre-acupuncture, paradistanceacupuncture, and control groups received 5 μL acetic acid (200 mL/L HAc) injection after a same course of electroacupuncture (EA) treatment (4 Hz, 0.6 mA, 0.45 ms,45 min for 4 d). The rats in these three groups recovered within 4 d. The acupuncture group received EA therapy for 4 d, after HAc injection. The stomach was dissected to compare the pathological structures of ulcer. Also c-Fos activation in the nuclei of solitary tract (NTS) was observed under microscope after regular immunohistochemistry staining of brain stem sections.RESULTS: The number of ulcers was different among the four groups, especially between control group and paradistance-acupuncture group or pre-acupuncture group. In the latter group, the number of ulcers was much less. The gastric ulcer area was consistent with the histopathological results, indicating that pre-acupuncture had an obvious therapeutic effect on gastric ulcers.Acupuncture had a very modest effect and paradistanceacupuncture had no effect on gastric ulcers. No therapeutic effect was found in the control group. Fos-Li neurons in NTS induced by noxious gastric ulcer showed a significant difference between pre-acupuncture and control groups.CONCLUSION: Acupuncture before ulceration can obviously alleviate ulcer. The production of c-Fos proves that the vagus nerve mediates the induction of c-Fos in nuclei of solitary tract following experimental ulceration,suggesting that parasympathetic afferents promote the process of noxious visceral stimulation.

Hepatic fibrosis in biliary-obstructed rats is prevented by Ginkgo biloba treatment

AIM： To assess the antioxidant and antifibrotic effects of long-term Ginkgo biloba administration on liver fibrosis induced by biliary obstruction in rats. METHODS： Liver fibrosis was induced in male Wistar albino rats by bile duct ligation and scission （BDL）. Ginkgo biloba extract （EGb 761, 50 mg/kg.per d） or saline was administered for 28 d. At the end of the treatment period, all rats were killed. Serum aspartate aminotransferase （AST）, alanine aminotransferase （ALT）, and lactate dehydrogenase （LDH） levels were determined to assess liver functions and tissue damage, respectively. Tumor necrosis factor-α （TNF-α） was also assayed in serum samples. Liver tissues were taken for determination of the hepatic malondialdehyde （MDA） and glutathione （GSH） levels, myeloperoxidase （MPO） activity and collagen content. Production of reactive oxidants was monitored by chemiluminescence （CL） assay. Serum AST, ALT, LDH, and TNF-α levels were elevated in the BDL group as compared to control group and were significantly decreased by EGb treatment. RESULTS： Hepatic GSH level, depressed by BDL, was elevated back to control level in EGb-treated BDL group. Increase in tissue MDA level, MPO activity and collagen content due to BDL were also attenuated by EGb treatment. Furthermore, luminol and lucigenin CL values in BDL group increased dramatically compared to control and reduced by EGb treatment. CONCLUSION： Our results suggest that Ginkgo biloba protects the liver from oxidative damage following BDL in rats. This effect possibly involves the inhibition of neutrophil infiltration and lipid peroxidation; thus, restoration of oxidant and antioxidant status in the tissue.

Efficacy of Chinese medicine Yi-gan-kang granule in prophylaxis and treatment of liver fibrosis in rats

AIM:To investigate the efficacy of a Chinese medicine, Yi-gan-kang granule (granules for benefiting the liver), in prophylaxis and treatment of liver fibrosis in rats and its possible mechanism. METHODS: One hundred and forty Sprague-Dawley rats were randomly divided into seven groups (20 each): group 1, blank control group without any interference during the study; group 2, CCI4-induced liver fibrosis group; group 3, pig serum-induced liver fibrosis group; group 4, prophylaxis group of CCl4-induced liver fibrosis by Yi-gan-kang; group 5, prophylaxis group of pig serum-induced liver fibrosis by Yi-gan-kang; group 6, treatment group of CCI4-induced liver fibrosis by Yi-gan-kang; group 7, treatment group of CCI4-induced liver fibrosis by Yi-gan-kang. At wk 6,10,14 and 20 (baseline for CCl4., or big serum induction), five rats in each group were anesthetized and their livers were removed for pathological studies including immunohistochemical studies for α-SMA, type I collagen and In situ hybridization of tissue inhibitor of metalloproteinase-1 (TTMP-1) mRNA of hepatic stellate cells (HSCs). Anti-lipid peroxidation in isolated mitochondria and 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) colorimetric assay for proliferation and terminal deoxynucleotidyl transferase-medicated dUTP-biotin nick end-labeling (TUNEL), flow cytometry and electron microscopy for apoptosis in isolated HSCs were also studied. RESULTS: The mean number of pseudolobuli at wk 10, 14 and 20 in the prophylaxis group was significantly less than that in the control group (P<0.05 or 0.01). The effect of prophylaxis at wk 14 in CCI4 rats and at wk 10 in pig serum-induced rats was much better than that of treatment group (P<0.01). The thickness (in μm) of fibers both in pig serum-induced prophylaxis and in treatment groups at wk 14 and. 20 was significantly less than that in control group (P<0.05). The number of fibers both in prophylaxis and in treatment groups from wk 10 or 14 to 20 was significantly less than that in control group (P<0.05 or P<0.01). The tissue HSC positive rates of type I collagen, α-SMA and TIMP-1 mRNA, which represented the active phenotype of HSCs in tissues, remained very high from wk 6 to the end of model making in control group. While in prophylaxis group, they were at a relatively low level. In treatment group, there was a gradual decreasing trend. Time- and dose-dependent effects of anti-lipid peroxidation on isolated mitochondria, cell proliferation and apoptosis in cultured HSCs were also observed during the study. CONCLUSION: Yi-gan-kang can effectively inhibit or inverse the course of liver fibrogenesis in CCI4- and pig serum-induced rat models.

Protective effect of Weikang decoction and partial ingredients on model rat with gastric mucosa ulcer

AIM: To investigate the protective mechanisms of Weikang (WK) decoction on gastric mucosae. METHODS: Ninety rats were randomly divided into nine groups of 10 each, namely group, model group, group with large WK dosage, group with medium WK dosage, group with small WK dosage, group with herbs of jianpiyiqi (strengthening the spleen and replenishing qi), group with herbs of yangxuehuoxue (invigorating the circulation of and nourishing the blood), group with herbs of qingrejiedu (clearing away the heat-evils and toxic materials), group with colloidal bismuth pectin (CBP) capsules. According to the method adopted by Yang Xuesong, except normal control group, chronic gastric ulcer was induced with 100% acetic acid. On the sixth day after moldmaking, WK decoction was administered, respectively at doses of 20, 10 and 5 g/kg to rats of the WK groups, or the groups with herbs of jianpiyiqi, yangxuehuoxue and qingrejiedu, 10 ml/kg was separately administered to each group every day. For the group with CBP capsules, medicine was dissolved with water and doses 15 times of human therapeutic dose were administered (10 mL/kg solution containing 0.35% CBP). Rats of other groups were fed with physiological saline (10 ml/kg every day). Administration lasted for 16 d. Rats were killed on d 22 after mold making to observe changes of gastric mucosa. The mucus thickness of gastric mucosa surface was measured. Levels of epidermal growth factor (EGF) in gastric juice, nitric oxide (NO) in gastric tissue, endothelin (ET) in plasma, superoxide dismutase (SOD) in plasma, malondialdehyde (MDA) in plasma and prostaglandin I2 (PGI2) were examined. RESULTS: Compared with control group, ulceration was found in gastric mucosa of model group rats. The mucus thickness of gastric mucosa surface, the levels of EGF, NO, 6-K-PGF1α and SOD decreased significantly in the model group (EGF: 0.818±0.18 vs 2.168±0.375, NO: 0.213±0.049 vs 0.601±0.081, 6-K-PGF1α 59.7±6.3 vs 96.6±8.30, SOD: 128.6±15.0 vs 196.6±35.3, P<0.01),the levels of ET (179.96±37.40 vs 46.64±21.20, P<0.01) and MDA (48.2±4.5 vs 15.7±4.8, P<0.01) increased. Compared with model group, the thickness of regenerative mucosa increased, glandular arrangement was in order, and cystic dilative glands decreased, while the mucus thickness of gastric mucosa surface increased (20 g/kg WK: 51.3±2.9 vs 23.2±8.4,10 g/kg WK: 43.3±2.9 vs23.2±8.4,, 5 g/kg WK: 36.1±7.2 vs 23.2±8.4, jianpiyiqi: 35.4±5.6 vs 23.2±8.4, yangxuehuoxue: 33.1±8.9 vs 23.2±8.4, qingrejiedu: 31.0±8.0 vs 23.2±8.4 and CBP: 38.2±3.5 vs23.2±8.4, P<0.05-0.01).

A COMPARATIVE STUDY ON HYPOTHALAMIC MECHANISMS OF ANALGESIA INDUCED BY FOUR KINDS OF ACUPUNCTURE THERAPIES IN ADJUVANT ARTHRITIS RATS

Objective.. To compare the mechanisms of analgesia induced by four kinds of acupunture therapies at the trypothalamic level in adjuvant arthritic rats. Methods： Forty-eight SD rats were randomized into normal, model, electroacupuncture （EA）, filiform needle （FN）, pricking blood-letting （BL） and point injection （PI） groups, with 8 cases in each. EA （20-100 Hz, 2-4 V and duration of 20 min）, FN, BL PI were respectively applied to “Kunlun” （昆仑 BL 60）. Arthritis model was established by injecting complete Freund＇s adjuvant （0.1 mL） into the rat＇s right foot pad. Behavioral reactions, pain threshold （latancy of tail flick to heat stimulation） and local swelling severity （foot volurne） were detected; the cordents of β-endorphin （β-EP） and α- drenocortiootropin （ACTH） were assayed with radioimmunoassay; and the expression of pro-opi-omelanocortin （POMC） mRNA in hypot were determined with hybridization method. Results： The pain threshold was significantly enhanced by all the four kinds of acupuncture therapies, and the effects of EA and PI were more obvious （P〈0.05, P〈0.01）. The severity of local swelling was markedly alleviated by all the four kinds of acupuncture therapies （ P〈 0.01 ） without significant differences among them （P 〉 0.05）. The content of β-EP in the hypothalamus was obviously elevated by EA and FN （P〈 0.05, P 〈 0.01 ）, and the effect of EA was more obvious, but no marked effect of BL or PI on β-EP was found （ P 〉0.05）. The content of ACTH in hypothalamus was considerably elevated by PI （P〈0.05）, but not by the other three therapies. The expression of PCMCmRNA in hypothalamus was significantly strengthened by EA and FN （P〈0. 01）, but not by the other two therapies. Conclusion：EA, flliform needle, blood-letting and point-injection all can produce analgesic effect in adjuvant arthritis rats, the effect of EA and filiform needie may be related to their resultant increase of hypothalamic β-EP, and that of point-injectiON related to the increase of hypothalamic ACTH level.

EFFECT OF ACUPUNCTURE ON HYPERLEPTINAEMIA AND HYPERINSULINEMIA IN OBESITY RATS

Objective: To observe the effect of acupuncture on hyperleptinaemia and hyperinsulinemia for studying its underlying mechanism about anti-obesity and reducing blood lipid in obesity rats. Methods: A total of 80 SD rats were randomized into normal control, model, acupuncture and medication groups, with 20 cases in each group. Hypothalamic obesity model was established by subcutaneous injection of 15% sodium glutamate (0.2 mL/10 g body weight), once daily and continuously for 5 days. “Zusanli” (足三里 ST 36), “Sanyinjiao”(三阴交 SP 6), “Guanyuan”(关元 CV 4) and “Zhongwan”(中脘 CV 12) were punctured and stimulated electrically (100 Hz, dense-sparse waves, and a suitable strength inducing local muscular tremor) for 15 min, once daily. In medication group, rats were fed with Sibutramine 4 mg/kg, once daily. After 4 weeks’ treatment, Lee’s index was detected, and serum leptin and insulin contents were determined by radioimmunoassay (RIA). Results: Compared with normal control group, Lee’s index, serum leptin and insulin contents of model group increased significantly (P<0.01). Comparison between acupuncture and model groups, Lee’s index and serum leptin of acupuncture group decreased significantly (P<0.01), and serum insulin level also lowered. In comparison with model group, Lee’s index, serum leptin and insulin levels of medication group also lowered. Comparison between acupuncture and medication groups showed that Lee’s index and serum leptin level of acupuncture group were significantly lower than those of the later group (P<0.01), displaying that the therapeutic effect of acupuncture is better than that of Sibutramine in lowering Lee’s index and serum leptin. No significant differences were found between acupuncture and medication groups in body weight and length and serum insulin(P>0.05). Conclusion: Acupuncture can effectively reduce Lee’s index, serum leptin and insulin contents in fasting obese rats, which may contribute to its effect in anti-obesity.

INFLUENCE OF ELECTROACUPUNCTURE OF “HUANTIAO” (GB 30) AT DIFFEREN TIME ON DUODENTAL ENDOCRINE CELLS IN RATS

Objective： To observe the influence of electroacupuncture （EA） at different time in a clay on the number of duodenal endocrine cells （argentaffin cells） in rats. Methods. Forty-eight male Wistar rats were evenly randomized into control and electroaoupuncfure （EA） groups which were further divided into 5：00, 11：00, 17：00 and 23：00 subgroups respectively. EA （4- 16 Hz in the frequency, 3 V in the strength, intermittent dense-sparse waves, and duration of 20 min） was applied to bilateral “Huan- tiao” （环跳 GB 30） at 5：00 o＇clock, 11：00 o＇clock, 17：00 o＇clock and 23：00 o＇clock separately for different subgroups. After EA, the animals were killed at once for sempling the middle part of cluodenum which was fixed in 10% formalin for 2 hours, then embed in paraffin. The tissue was cut into sections （ 10 μm）, mounted on glass slides and then processed according to Grimelius＇s methods. Results： The rumber of argentaffin cells in EA group was significantly fewer than that in control group at the same timewindow （23：00, P〈0.05）. No significant differences were found between control and EA groups in the number of cells at other time window （5：00, 11：00 and 17：00 o＇clock, P〉0.05）, suggesting that EA of “Huantiao”can markedly promote the secretion activity of endocrine cells at 11：00 o＇clock during night ferent time window in a day. Conclusion. The results suggest that the effects of EA are different at clifferent time window in a day.

Multi-central Clinical Research into Treating 80 Cases of Chronic Thrombocytopenia with Qi-supplementing and Yin-nourishing Therapy and Western Medicine

Objective: To probe the effects of qi-supplementing and yin-nourishing therapy (blood-increasing decoction and blood generating powder) on chronic thrombocytopenia. Methods: Two hundred patients with chronic thrombocytopenia were randomly divided into control (n=100) and test groups (n = 100) with Amino-polypeptide as a basic treatment for both. Test group patients consumed a blood-increasing decoction and blood-generating powder for 1-3 months. Improvements in platelet counts and TCM syndrome were observed. Results: One hundred and sixty-four (80 in the test group and 84 in the control group) of 189 total participants were treated for 3 months. The total effective rate in improving TCM syndrome was 95.00% in the test group and 79.76% in the control group (P<0.05). There was significant difference (P<0.05) in the accumulated score of TCM syndrome between the two groups treated at different time points. The total effective rate of platelet counts was 86.25% in the test group and 59.52% in the control group (P<0.05). There was a significant difference in platelet counts before and after treatment in the two groups (P<0.05). There was no significant differences in platelet count between the two groups treated for 1-2 months; however, a significant difference was found between the two groups after treatment for 3 months (P<0.05). Conclusions: After a 3-month treatment of chronic thrombocytopenia patients with qi-supplementing and yin-nourishing therapy, TCM syndrome was improved and platelet counts increased with no obvious side effects, and the quality of life of the participants was enhanced with noticeable long-term curative effects.

Comparison of the Network Structural Characteristics of Calcium Signaling Pathway in Cerebral Ischemia after Intervention by Different Components of Chinese Medicine

Objective:To explore the network control mechanism of the calcium signaling pathway in cerebral ischemic injury after intervention by the main components of Qingkailing(清开灵),i.e.Baicalin,Jasminoidin and their combination.Methods:Thirty mice were randomly divided into 5 groups,a baicalin group,a Jasminoidin group,a baicalin plus Jasminoidin group,a nimodipine group,and a model group(n=6).The global cerebral ischemia-reperfusion mouse model was established.The mice were administrated respectively by injection of baicalin,Jasminoidin,mixture of baicalin and Jasminoidin,and nimodipine into the caudal vein,with the model group given no any drug.Three hours after operation,the brain was removed and sectioned.After calculation of cerebral ischemic area by 2,3,5-triphenyltetrazolium staining,the percentage of infarct volume was calculated.The total RNA of the mouse brain tissue was extracted to obtain the whole genome expression profile,and the differentially expressed genes related to the calcium signaling pathway was analyzed with Bayesian network structures.Results:Compared with the model group,the ischemic area was significantly reduced in the baicalin group,the Jasminoidin group,the Baicalin plus Jasminoidin group(all P<0.05).The ischemic area in the baicalin plus Jasminoidin group was smaller than the other three groups(all P<0.01).In the gene regulatory network structures of calcium signaling pathway,the average length and equitability were the highest in the baicalin plus Jasminoidin group,followed by the nimodipine group.Conclusion:Compared with a single component,combination of Baicalin and Jasminoidin can more obviously intervene in the overall expression of calcium signaling pathway,and the mechanism is related with the aggregation characteristic of the gene expression network.

Integrated Chinese-western therapy versus western therapy alone on survival rate in patients with non-small-cell lung cancer at middlelate stage

OBJECTIVE: To compare the effects of integrated Chinese-Western therapy versus Western therapy alone on the survival rate of patients with non-small-cell lung cancer (NSCLC) at middle-late stage and to evaluate prognostic factors. METHODS: We selected 98 inpatients with middle-late stage NSCLC diagnosed from March 2009 to March 2011 and randomly divided them into two groups, with 49 cases in each group, and the clinical data were analyzed retrospectively.The control group was treated by the combined methods of Western Medicine, including chemotherapy, supportive treatment and symptomatic treatment. The observation group was treated by injection and prescriptions of Chinese medicine based on Traditional Chinese Medicine syndrome differentiation and by the same combined methods of western treatment used in the control group. After treatment, the survival rates of the patients were compared by the stage of cancer and evaluation of 24 prognostic factors analyzed by a Cox regressionmodel, and the clinical data were statistically analyzed. RESULTS: The survival rates of all patients were over 90.0% at 1 and 3 months after treatment with no significant differences between the two groups (P>0.05); In the observation group the survival rates at 6 months and 1 year were 93.4% and 42.8%, respectively, being superior to 85.6% and 18.3% in the control group (P<0.05). The median survival time in the observation group was superior to the control group (P<0.05); The effects of 24 prognostic factors were significantly better in the observation group than in the control group (P<0.05). CONCLUSION: Integrated Chinese-western therapy can significantly improve the survival rate in patients with middle-late stage NSCLC and improve prognostic factors compared with western therapy alone.

Platelet proteomics and its advanced application for research of blood stasis syndrome and activated blood circulation herbs of Chinese medicine

The development of novel and efficient antiplatelet agents that have few adverse effects and methods that improve antiplatelet resistance has long been the focus of international research on the prevention and treatment of cardiovascular and cerebrovascular diseases.Recent advances in platelet proteomics have provided a technology platform for high-quality research of platelet pathophysiology and the development of new antiplatelet drugs.The study of blood stasis syndrome(BSS)and activated blood circulation of traditional Chinese medicine(TCM)is one of the most active fields where the integration of TCM and western medicine in China has been successful.Activated blood circulation herbs(ABC herbs)of Chinese medicine are often used in the treatment of BSS.Most ABC herbs have antiplatelet and anti-atherosclerosis activity,but knowledge about their targets is lacking.Coronary heart disease(CHD),BSS,and platelet activation are closely related.By screening and identifying activated platelet proteins that are differentially expressed in BSS of CHD,platelet proteomics has helped researchers interpret the antiplatelet mechanism of action of ABC herbs and provided many potential biomarkers for BSS that could be used to evaluate the clinical curative effect of new antiplatelet drugs.In this article the progress of platelet proteomics and its advanced application for research of BSS and ABC herbs of Chinese medicine are reviewed.

Biomedical applications of shape-memory polymers:how practically useful are they?

Shape-memory effect(SME) is the ability of a material to change its dimension in a predefined way in response to an external stimulus. Polymers that exhibit SME are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to approved products is extremely low, with mostly nitinolbased devices being approved. In this review, the general aspects of the different types of stimuli that can be used to activate SME are reviewed and sterilization issues of shape-memory polymer(SMP)-based medical devices are addressed. In addition, the general usefulness as well as the limitations of the shape-memory effect for biomedical applications are described.
