[Study on medication regularity of chronic atrophic gastritis in Beijing-Tianjin-Hebei region based on latent structure model].

To explore the etiology, pathogenesis, distribution of syndromes and the rule of medication of chronic atrophic gastritis(CAG) in Beijing-Tianjin-Hebei region based on the latent structure model. Chronic atrophic gastritis of 279 cases in Beijing-Tianjin-Hebei region were extracted from the established database of spleen and stomach diseases of famous veteran Chinese medicine experts. The latent structure models of symptoms and drugs of chronic atrophic gastritis were constructed by using Lantern 3.1.2 software, and the latent structure models were interpreted. SAS 10.0 software was used to mine association rules of drugs and symptoms. The constitutional characteristics of patients with chronic atrophic gastritis in Beijing-Tianjin-Hebei region were "turbid toxin and damaging Yin". The common syndromes were turbid toxin, deficiency of stomach Yin, stagnation of liver and stomach, stagnation of liver and stomach Qi, obstruction of stomach collaterals and blood stasis, and weakness of spleen and stomach. Common medicines are Lobeliae Chinensis Herba, Scutellariae Barbatae Herba, Amomi Fructus Rotundus, Amomi Fructus, Poria, Isatidis Radix, Artemisiae Scopariae Herba, Scorpio, Coptidis Rhizoma, Lilii Bulbus, Linderae Radix, Phragmitis Rhizoma, Ophiopogonis Radix, Pogostemonis Herba, Eupatorii Herba, Magnoliae Officinalis Cortex, Aurantii Fructus Immaturus. Common prescriptions are Baihe Wuyao Powder, Danggui Shaoyao Powder, Xiaoyao Pills, Xiangsu Powder, Dachengqi Decoction, Zuojin Pills, Qingzhong Decoction, Zhishi Daozhi Pills, etc. The application of latent structure model and correlation analysis in the empirical study of famous and veteran Chinese medicine experts is in line with the research direction of modern Chinese medicine "traditional Chinese medicine + X". The conclusions obtained effectively tap the experience of famous and veteran TCM experts, and provide a data and visual clinical reference and prescription compatibility for young TCM physicians in the treatment of chronic atrophic gastritis based on syndrome differentiation.

[Medicine-syndrome research and analysis of professor Li Dian-gui in treating chronic atrophic gastritis with intestinal metaplasia].

In this article, medication characteristics of professor Li Dian-gui in treating chronic atrophic gastritis with intestinal metaplasia(CAGIM) were analyzed through traditional Chinese medicine inheritance support system(version 2.5). 276 cases and 625 prescriptions were collected to analyze five types of traditional Chinese medicine(TCM) syndromes and the medicine-syndrome correlation. The results showed that medication characteristics of professor Li Dian-gui in treating CAGIM included drug combination of aromatic medicine bitter-cold herbs, preferring to activating to invigorate the spleen and good at using the qi-regulating drugs. It demonstrated that we can adopt the therapy of Huazhuo Jiedu and Xingpi Xingqi therapies in treating CAGIM in addition to the traditional approach of nourishing Yin and activating blood circulation, opening up a novel approach for TCM in healing the pathema.

[Effect of huazhuo jiedu hewei recipe on the mechanism of angiogenesis in precancerous lesions of gastric cancer rats].

OBJECTIVE: To explore the possible angiogenesis mechanism of Huazhuo Jiedu Hewei Recipe (HJHR) in preventing and treating precancerous lesions of gastric cancer (PLGC). METHODS: Totally 66 Wistar rats were randomly divided into 6 groups, i.e., the normal control group, the model group, the retinoic acid (RA) group, the high dose HJHR group, the middle dose HJHR group, the low dose HJHR group, 11 in each group. PLGC model was duplicated by inserting a spring with Helicobacter. Corresponding medicines were administered to rats in each medicated group once daily by gastrogavage, 2 mL each time for 12 successive weeks. The effect of HJHR on hypoxia induced factor (HIF-1alpha) and vascular endothelial growth factor (VEGF) of PLGC in chronic atrophic gastritis (CAG) rats' gastric mucosa was observed by immunohistochemical assay and Western blot method. RESULTS: Compared with the normal control group, the expression of VEGF and HIF-1alpha increased in the model group (P < 0.05). Compared with the model group, the expression of VEGF and HIF-1alpha decreased in each medicated group (P < 0.05). Besides, they were lower in the high and middle dose HJHR groups than in the RA group and the low dose HJHR group (P < 0. 05). There was no statistical difference between the low dose HJHR group and the RA group (P > 0.05). CONCLUSION: HJHR could prevent and treat PLGC of CAG rats possibly through decreasing the expression of HIF-1alpha and VEGF in a dose-dependent manner.

[Effect of huazhuo jiedu recipe on gastric juice compositions and tumor markers in patients with chronic atrophic gastritic precancerosis].

OBJECTIVE: To observe clinical efficacy of Huazhuo Jiedu Recipe (HJR) on chronic atrophic gastritic precancerosis (CAGP), and its effect on contents of lactic acid, total acid, free acid, and nitrite in the gastric juice, as well as tumor markers in gastric juice and blood. METHODS: Two hundred and twenty-nine patients with CAGP were randomly assigned to two groups, the 119 patients in the treated group orally took HJR and the 110 patients in the control group orally took Weifuchun Tablet. The therapeutic course for all was three months, two courses in total. The therapeutic efficacy, changes of gastric acid contents before and after treatment were observed, and the tumor markers in the gastric juice and blood were detected using electrochemical luminescence immunoassay. RESULTS: The pathological effective rate was 83.2% (99/119) in the treated group and 60.9% (67/110) in the control group, showing significant difference between the two groups (P <0.05). The total acids and free acids in the gastric juice were significantly improved, contents of lactic acid and nitrite were significantly lowered in the two groups. Both contents of carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen72-4 (CA72-4), and carbohydrate antigen125 (CA125) in the gastric juice and serum were significantly lowered after treatment in the treated group (P<0.05). Compared with the normal control group, the therapeutic effect was more obvious in the treated group (P<0.05). CONCLUSIONS: HJR could stimulate the gastric membranous secretion, enhance contents of total acids and free acids. It could prevent the further progress of CAGP by decreasing contents of lactic acid and nitrite in the gastric juice, and lowering contents of CEA, CA19-9, CA72-4, and CA125 in the gastric juice and serum.

[Clinical curative effect of combination between medicine and acupoint flow on SOD, NO in patients with ulcerative colitis].

OBJECTIVE: To investigate the clinical curative effect of the combination between medicine and acupoint flow on SOD, NO in patients with ulcerative colitis. METHOD: Two hundred sixty two patients with ulcerative colitis were randomly divided into four groups: the patients in traditional Chinese medicine group were fed with changpikang, the patients in ear acupoint group were pasted and pressed spleen, large intestine, sympathesis, subcortex; the patients in medicine and acupoint group were taken with Changpikang and ear acupoint; the patients in treatment group were treated by taking sulfasalazine, with a treatment course of four weeks. The changes of SOD, NO before and after treatments were recored. RESULT: There was a significant difference between four groups before and after treatment (P < 0.05), medicine and acupoint group was superior to that others (P < 0.05). CONCLUSION: The method of combination between medicine and acupoint could increase the contents of SOD, decrease the level of NO, elevate the potential of organism to resist oxygen free radical and promote intestinal tract ulcer concrescence.

[Effects of Chinese herbs for cool-moistening and freeing collaterals on serum gastrin and surface electrogastrogram in patients of diabetes mellitus with gastroparesis].

OBJECTIVE: To explore the effect of Chinese herbs (CH) for cool-moistening and freeing collaterals on gastro-dynamic disturbance in patients of diabetes mellitus type 2 with gastroparesis (DM-GP). METHODS: Fifty-three patients of DM-GP were enrolled and treated with CH (n = 28) and Cisapride (n = 25) respectively for 4 weeks, the changes of gastrin and electro-gastrogram (EGG) before and after treatment were observed. RESULTS: After treatment, the EGG improved significantly, showing the rhythm significantly improved, and level of serum gastrin lowered significantly, as compared with those before treatment, the difference was significant (P<0.01), but insignificant difference was found between the two groups. Fifteen patients in each group were followed-up afar stopping medication for 3 months, recurrence occurred in 1 patient of CH treated group, and 2 patients of Cisapride treated group. No adverse reaction was found in the rest patients. CONCLUSION: CH could obviously improve the gastro-intestinal motility and hormones abnormality.

[An animal model of alcoholic fatty liver and the prevention and treatment with New Qinggan Decoction].

OBJECTIVE: To establish an animal model of alcoholic fatty liver (AFL) and to observe the prevention and treatment with New Qinggan Decoction (NQGD). METHODS: Female SD rats were exposed to the mixture of white spirit and corn oil continuously for up to 6 weeks via an intragastric feeding protocol. The pathologic alteration of the liver and the changes of serum lipid were observed, and the effect of NQGD for preventing and treating AFL was studied. RESULTS: Wide hepatic steatosis was induced in model group rats. Serum triglyceride (TG) and total cholesterol (TC) of the model group were higher than those of the normal group (P<0.01). Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of the model group were higher than those of the normal group (P<0.05). In NQGD group, hepatic steatosis was milder than that in the model group, and serum TG, TC, AST, ALT descended significantly as compared with the model group (P<0.01). CONCLUSION: AFL model of rats established by feeding the mixture of white spirit and corn oil is similar to the episode of the human AFL, and is easy to intervene with medicine. NQGD can prevent the occurrence of AFL in this model.
