RESUMEN
Shidan granule (SDG), a traditional Chinese medicine in-hospital preparation, has been demonstrated to exert good effects on chronic atrophic gastritis (CAG) in clinics. However, the underlying mechanism of SDG against CAG is still unclear. This study utilized an untargeted plasma metabolomics approach to explore the potential mechanism of SDG in CAG rats using LC-MS and pattern recognition analysis. The results indicated that SDG could effectively improve the biochemical indexes and pathology features of CAG rats. Nineteen potential biomarkers (variable importance in projection > 1 and P < 0.05) contributing to CAG progress were identified. After SDG intervention, 17 biomarkers were obviously restored to normal levels. Further metabolic pathway analysis showed that aspartate and glutamate metabolism, arachidonic acid metabolism, arginine and proline metabolism, and TCA cycle were the most related pathways for SDG treatment. Based on these findings, the main mechanisms of SDG against CAG might be attributed to the regulatory effects of energy balance, inflammatory suppression, and improvement in disturbed amino acid and lipid metabolism. This study provided information for the mechanism research of SDG against CAG and would promote its clinical application.

ETHNOPHARMACOLOGICAL RELEVANCE: Huangqi Jianzhong Tang (HQJZ), a celebrated traditional Chinese medicine (TCM), is commonly used for treatment of chronic atrophic gastritis (CAG) in China. AIM OF THE STUDY: We aimed to screen out the material basis of HQJZ against CAG. MATERIALS AND METHODS: CAG rat model was constructed by alternant administrations of ammonia solution and sodium deoxycholate, and the hunger disorder method. Body weight, biochemical indexes and histopathological exam were used to evaluate the efficacy of HQJZ. 1H NMR-based metabonomics was employed to analyze the urine metabolic features of HQJZ deviated from CAG rats. SystemsDock analysis was utilized to explore the active compounds involved into the efficacy of HQJZ against CAG based on the targeted metabolic biomarkers. RESULTS: The metabonomic results indicated that HQJZ could significantly improve 16 urinary perturbed metabolites in CAG rats, which were involved into the metabolism of energy and amino acids. And then 28 related proteins and genes were selected out to be the potential targets of HQJZ against CAG based on the six key metabolites closely correlating with biochemical indexes (α-ketoglutarate, valine, sarcosine, glycine, malonate and fumarate). 71 previous identified compounds were docked through systemsDock-aided molecular docking experiments. And the constructed herb-component-protein-metabolite interaction network (HCPMN) revealed the associations between the herbal formulae and CAG. At last, 51 compounds of them were screened as promising active constitutes for the inhibition of CAG, which could act on various targeted proteins. CONCLUSIONS: he results showed that the approach integrating of metabonomics and systemsDock is a powerful tool to obtain the material basis and regulatory mechanism of TCM formula.

AIM: To explore the correlation between serum vitamin B12 level and peripheral neuropathy in patients with chronic atrophic gastritis (CAG). METHODS: A total of 593 patients diagnosed with chronic gastritis by gastroscopy and pathological examination from September 2013 to September 2016 were selected for this study. The age of these patients ranged within 18- to 75-years-old. Blood pressure, height and weight were measured in each patient, and the body mass index value was calculated. Furthermore, gastric acid, serum gastrin, serum vitamin and serum creatinine tests were performed, and peripheral nerve conduction velocity and Helicobacter pylori (H. pylori) were detected. In addition, the type of gastritis was determined by gastroscopy. The above factors were used as independent variables to analyze chronic gastritis with peripheral neuropathy and vitamin B12 deficiency risk factors, and to analyze the relationship between vitamin B12 levels and peripheral nerve conduction velocity. In addition, in the treatment of CAG on the basis of vitamin B12, patients with peripheral neuropathy were observed. RESULTS: Age, H. pylori infection, CAG, vitamin B9 and vitamin B12 were risk factors for the occurrence of peripheral nerve degeneration. Furthermore, CAG and H. pylori infection were risk factors for chronic gastritis associated with vitamin B12 deficiency. Serum vitamin B12 level was positively correlated with sensory nerve conduction velocity in the tibial nerve (R = 0.463). After vitamin B12 supplementation, patients with peripheral neuropathy improved. CONCLUSION: Serum vitamin B12 levels in patients with chronic gastritis significantly decreased, and the occurrence of peripheral neuropathy had a certain correlation. CAG and H. pylori infection are risk factors for vitamin B12 deficiency and peripheral neuropathy. When treating CAG, vitamin B12 supplementation can significantly reduce peripheral nervous system lesions. Therefore, the occurrence of peripheral neuropathy associated with vitamin B12 deficiency may be considered in patients with CAG. Furthermore, the timely supplementation of vitamin B12 during the clinical treatment of CAG can reduce or prevent peripheral nervous system lesions.

We present a case of a 50-year-old female patient with a history of depressive disorder and anaemia (attributed to menorrhagias). She was admitted to the cardiology department with symptoms of fatigue on moderate exertion for several months, with worsening in the month before hospitalisation. Echocardiography revealed a severe mitral stenosis of rheumatic aetiology. Laboratory tests showed microcytic and hypochromic anaemia, reduced iron stores and vitamin B12 levels, and positive serum antiparietal cells autoantibodies. Endoscopy showed focal areas of erythema in the stomach, corresponding histologically to chronic atrophic gastritis. In this context, two distinct clinical entities were diagnosed in the same patient: severe rheumatic mitral stenosis and autoimmune gastritis. The patient was started on vitamin B12 and iron supplementation and underwent surgical correction of the valvular disease. There was symptomatic improvement in her signs of fatigue.

Evidence has shown that both C-reactive protein (CRP) and serum amyloid component A (SAA) are increased in individuals with gastritis and stomach cancer. Controlling the level of these biomarkers by inhibiting the gastric infection with high doses of ascorbic acid may reduce the risk of carcinogenesis. A population-based double-blind randomised controlled trial in a Japanese population with atrophic gastritis in an area of high stomach cancer incidence was conducted between 1995 and 2000. Daily doses of 50 or 500 mg vitamin C were given, and 120 and 124 participants completed the 5-year study, respectively. Although serum ascorbic acid was higher in the high-dosage group (1.73 (SD 0.46) µg/l) than in the low-dosage group (1.49 (SD 0.29) µg/l, P< 0.001), at the end of the study, no significant difference was observed for CRP between the low- and high-dosage groups (0.39 (95 % CI 0.04, 4.19) mg/l and 0.38 (95 % CI 0.03, 4.31) mg/l, respectively; P= 0.63) or for SAA between the low- and high-dosage groups (3.94 (95 % CI 1.04, 14.84) µg/ml and 3.85 (95 % CI 0.99, 14.92) µg/ml, respectively; P= 0.61). Vitamin C supplementation may not have a strong effect on reducing infections in individuals with atrophic gastritis.

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.

OBJECTIVES: The objective of this study was to test the efficacy of three different treatment modalities on the reduction of serum anti-gastric parietal cell autoantibody (GPCA) level in GPCA-positive oral lichen planus (OLP) patients. MATERIALS AND METHODS: Of 147 GPCA-positive OLP patients, 100 were treated with levamisole plus vitamin B12, 10 with vitamin B12 only and 37 with levamisole only. The serum GPCA levels in 147 OLP patients were measured at baseline and after treatment. RESULTS: Treatment with levamisole plus vitamin B12 for a period of 2-50 months and treatment with vitamin B12 only for a period of 4-44 months could effectively reduce the high serum GPCA level to undetectable level in 100 and 10 OLP patients, respectively. However, treatment with levamisole only for a period of 2-50 months could not modulate the high mean serum GPCA titer to a significantly lower level in 37 OLP patients. A 92% GPCA recurrence rate was found in 25 OLP patients receiving no further vitamin B12 treatment during the GPCA-negative remission period. CONCLUSION: For GPCA-positive OLP patients, treatment modality containing vitamin B12 can effectively reduce the high serum GPCA level to undetectable level. OLP patients with underlying autoimmune atrophic gastritis trait should receive a maintenance vitamin B12 treatment for life.

OBJECTIVE: The objective of this observational study was to estimate the prevalence of advanced atrophic corpus gastritis (ACG) among Finnish adult volunteers without specific complaints using a biomarker blood test. The objective also was to assess the feasibility and acceptance of the biomarker test among the volunteers. MATERIALS AND METHODS: GastroView biomarker test (Biohit Oyj, Helsinki, Finland) was performed on mostly fingerprick blood samples from 4,256 volunteers (average age 56 years, range 18-92 years), independent of symptoms. GastroView biomarker test was offered to citizens at public events during 2007-2009. The test consisted of the measurement of pepsinogen I and II levels (and ratio) and H. pylori IgG antibody level in plasma by ELISA. RESULTS: Altogether 3.5% (150 individuals) of all 4,256 volunteers had ACG. In the age group of 70 or over, the prevalence of ACG increased to 8% (62 individuals). Altogether 19% (819 individuals) of all volunteers and 37% (56 individuals) of those with ACG had an ongoing H. pylori infection. In volunteers with ACG, the diagnosis was new in 95% (142 individuals), 5% (7 individuals) had received vitamin B12 supplementation and 13% (20 individuals) had received PPI medication according to a self-administered questionnaire; and 26% (39 individuals) reported gastrointestinal reflux like symptoms. CONCLUSIONS: This study shows that advanced ACG is a common disease among Finnish adults, and remains to be undiagnosed in most under the current healthcare practice. The biomarker test shows high feasibility and acceptance among the general public, and is simple to perform even in "field" conditions.

BACKGROUND: Although a number of reports regarding the role of reactive oxygen species (ROS) as the first step in cancer induction exist, few studies have investigated how vitamin C influences ROS in human plasma. AIM OF THE STUDY: Using the ROS assay system, a method recently established by one of the authors, we aimed to evaluate the effect of vitamin C supplementation on serum ROS among subjects diagnosed with chronic gastritis. METHODS: A total of 244 Japanese subjects with atrophic gastritis were randomized to take 5-year supplementation of either 50 mg or 500 mg of vitamin C. RESULTS: The adjusted difference in the changes of total ROS between baseline and after 5-year supplementation was statistically significant between the intervention groups: 2.70 decrease (corresponds to 1.26% decrease) in the high-dose group and 4.16 increase (corresponds to 3.79% increase) in the low-dose group, p for difference = 0.01. CONCLUSION: Vitamin C was suggested to reduce oxidative stress among subjects with atrophic gastritis.

OBJECTIVE: To determine the serum vitamin B(12) status of older New Zealanders and to assess the impact of atrophic gastritis on vitamin B(12) status. DESIGN: A cross-sectional nationally representative population-based survey. METHOD: Serum vitamin B(12) concentrations were used to assess vitamin B(12) status. The presence and severity of atrophic gastritis was classified using serum pepsinogen I and II. SUBJECTS: A total of 466 noninstitutionalized urban and rural dwelling New Zealanders aged 65 y or older who participated in the 1997 National Nutrition Survey. RESULTS: The prevalence of deficient (<148 pmol/l) and marginal (148-221 pmol/l) serum vitamin B(12) concentrations was 12 and 28%, respectively. The prevalence of atrophic gastritis was 6.7% (severe 3.1%, mild-moderate 3.6%). While atrophic gastritis increased the relative risk (RR, 95% CI) of having a deficient or marginal serum vitamin B(12) concentration by 21-fold (6-67) and five-fold (1-17), respectively, those who had atrophic gastritis made up only 33 and 6% of the participants with deficient or marginal serum vitamin B(12) concentrations. An intake of vitamin B(12) from food that exceeded the recommended dietary allowance (2.4 mug/day) did not protect against deficient (RR 0.5; 95% CI: 0.2, 1.2) or marginal (RR 0.9; 95% CI: 0.5, 1.7) serum vitamin B(12) status. Vitamin B(12) supplement users had a reduced risk of having deficient and marginal vitamin B(12) status (RR 0.3; 95% CI: 0.1, 0.8). CONCLUSIONS: There is a relatively high prevalence of deficient and marginal serum vitamin B(12) concentrations among older New Zealanders. However, the prevalence of atrophic gastritis was low in the New Zealand elderly compared with other surveys. Although atrophic gastritis was a risk factor for low vitamin B(12) status, it did not fully explain the prevalence of low serum vitamin B(12).

BACKGROUND/AIMS: Recent reports support the possible association between Hp infection and iron deficiency anemia. In the present study, the effects of the eradication therapy on iron deficiency anemia were investigated. METHODOLOGY: Fourteen women with iron deficiency anemia were enrolled (mean age: 36.4 years; range: 20-52 years old). None of the patients received iron supplementation. Several examinations including upper and lower gastrointestinal endoscopy were performed to reveal any gastrointestinal bleeding sites in all patients. Gastric biopsies during endoscopy were taken from the subjects except one whose serum anti-Hp IgG was positive. After diagnosing the Hp infection by means of microbiology, histology and Gram stain, a combination therapy consisting of lansoprosol, clarithromycin and amoxicillin was administered to each patient. Hematologic examinations and the body iron status were evaluated periodically, following the eradication therapy. RESULTS: Endoscopic findings were as follows: Seven patients with antral gastritis, two patients with pangastritis, whereas five patients were found to be endoscopically normal. None of the subjects were found to have gastrointestinal bleeding of any type. Serum hemoglobin, iron and transferrin saturations of the patients were found to be increased at 20-24 weeks of follow-up after the eradication therapy. Serum ferritin levels were not found to be increased. CONCLUSIONS: Hp infection may be involved in cases of iron deficiency anemia of unknown origin, and the eradication of the infection may improve blood parameters other than serum ferritin levels.

OBJECTIVE: To study regulative action of mica monomer granule preparation on gastrin (GAS), somatostatin (SS) and G cells as well as D cells of gastric mucosa in experimental chronic atrophic gastritis (CAG) rat. METHOD: CAG rats were treated with mica monomer granule preparation with three different dosages--high, moderate and low level respectively. Changes of blood serum GAS, blood plasma SS and G cells as well as D cells of gastric mucosa in CAG rats were observed and detected with ELISA method, RIA method and immunocytochemistry method. RESULT: Mica monomer granule of three different dosages could increase the quantity of G cells as well as D cells of gastric mucosa and the concentration of blood serum GAS and decrease the content of blood plasma SS in CAG rat at different level respectively. It was more effective in high and moderate dosage groups. CONCLUSION: Mica has the pharmacological action of protecting gastric mucosa, promoting the palingenesis of gastric gland and enhancing blood stream of gastric mucosa consequently to abate the inflammation reaction of gastric mucosa. Its effective mechanism is associated with the neuroendocrine regulative mechanism of promoting the secretion of gastric acid and gastric pepsin by increasing the amount of G cells as well as D cells and the concentration of blood serum GAS, and reducing inhibiting action on GAS secretion and enhancing the secretion of GAS by decreasing the content of SS.

We conducted a population-based, double-blind, randomized controlled trial to examine the effect of vitamin C supplementation on serum pepsinogen (PG) level, Helicobacter pylori (H. pylori ) infection, and cytotoxin-associated gene A (Cag A) status. Subjects aged 40 to 69 years living in one village in Akita prefecture, a high-risk area for gastric cancer in Japan, were recruited through annual health check-up programs. Among 635 subjects diagnosed as having chronic gastritis on the basis of serum PG levels, after excluding ineligible cases, 439 subjects were assigned to one of four groups using a 2 x 2 factorial design (0 or 15 mg/day beta-carotene and 50 or 500 mg/day vitamin C). However, based on the results from two beta-carotene trials in the United States, we discontinued beta-carotene (vitamin C supplementation was continued). Finally, 120 subjects in the low-dose group (vitamin C 50 mg), and 124 subjects in the high-dose group (vitamin C 500 mg) completed the 5-year supplementation. The difference in the change of PGI/II ratio between baseline and after 5-year follow up was statistically significant between the intervention groups among those who completed the supplementation: - 0.25 for the low-dose group and - 0.13 for the high-dose group (P = 0.046). To conclude, vitamin C supplementation may protect against progression of gastric mucosal atrophy.

OBJECTIVE: To investigate the effect of various combinations of Spleen invigorating and Dampness removing recipes and western medicine on level of serum epidermal growth factor (sEGF) in patients of chronic atrophic gastritis (CAG). METHODS: By means of Syndrome Differentiation three groups were divided as (1) Spleen invigorating I group (SI-I); (2) Spleen invigorating II group (SI-II); (3) Dampness removing group (DR); (4) western medicine group (WM); (5) healthy volunteers served as normal control group. The changes of symptoms and sEGF level were determined and compared between groups as well as before and after treatment. RESULTS: The sEGF in various groups of CAG were higher than that in the normal control (P < 0.01). In patients of SI-I and II groups, symptoms and pathological manifestations were improved significantly (P < 0.01), and sEGF dropped markedly after treatment (P < 0.01 and P < 0.05). The level of sEGF in DR raised after treatment (P < 0.05), but the level of sEGF in WM group lowered insignificantly. CONCLUSION: Inflammation of gastric mucosa could cause responsive elevation of sEGF in CAG patients. After treated with Spleen invigorating and Dampness removing Chinese drugs, the symptoms of CAG improved, simultaneously with the restoration of sEGF. sEGF could be taken as a sensitive index of the prognosis of CAG.

BACKGROUND: Previous research has identified a high risk of gastric carcinoma as well as a high prevalence of cancer precursor lesions in rural populations living in the province of Nariño, Colombia, in the Andes Mountains. METHODS: A randomized, controlled chemoprevention trial was conducted in subjects with confirmed histologic diagnoses of multifocal nonmetaplastic atrophy and/or intestinal metaplasia, two precancerous lesions. Individuals were assigned to receive anti-Helicobacter pylori triple therapy and/or dietary supplementation with ascorbic acid, beta-carotene, or their corresponding placebos. Gastric biopsy specimens taken at baseline were compared with those taken at 72 months. Relative risks of progression, no change, and regression from multifocal nonmetaplastic atrophy and intestinal metaplasia were analyzed with multivariate polytomous logistic regression models to estimate treatment effects. All statistical tests were two-sided. RESULTS: All three basic interventions resulted in statistically significant increases in the rates of regression: Relative risks were 4.8 (95% confidence interval [CI] = 1.6-14.2) for anti-H. pylori treatment, 5. 1 (95% CI = 1.7-15.0) for beta-carotene treatment, and 5.0 (95% CI = 1.7-14.4) for ascorbic acid treatment in subjects with atrophy. Corresponding relative risks of regression in subjects with intestinal metaplasia were 3.1 (95% CI = 1.0-9.3), 3.4 (95% CI = 1.1-9.8), and 3.3 (95% CI = 1.1-9.5). Combinations of treatments did not statistically significantly increase the regression rates. Curing the H. pylori infection (which occurred in 74% of the treated subjects) produced a marked and statistically significant increase in the rate of regression of the precursor lesions (relative risks = 8.7 [95% CI = 2.7-28.2] for subjects with atrophy and 5.4 [95% CI = 1.7-17.6] for subjects with intestinal metaplasia). CONCLUSIONS: In the very high-risk population studied, effective anti-H. pylori treatment and dietary supplementation with antioxidant micronutrients may interfere with the precancerous process, mostly by increasing the rate of regression of cancer precursor lesions, and may be an effective strategy to prevent gastric carcinoma.

Prior to a randomized controlled trial to prevent gastric cancer by oral supplementation of beta-carotene and vitamin C in a high-risk Japanese population, we examined the serum response to three-month oral supplementation of beta-carotene (0, 3, 30 mg / day) and vitamin C (0, 50, 1000 mg / day) by a three-by-three factorial design using 54 subjects (age range = 40 - 69 years). Serum concentrations of carotenoids, alpha-tocopherol, and ascorbic acid were examined at baseline, and one, two, and three-month points. Both serum beta-carotene and ascorbic acid were significantly higher in high-dose groups than in each placebo group during the supplementation. The serum beta-carotene increased gradually (597 - 830% increase) during the study, whereas the serum ascorbic acid reached nearly a steady-state at the one-month point and remained stable thereafter (88 - 95% increase). No statistically significant interaction between beta-carotene and vitamin C supplementations was observed either for serum beta-carotene or for serum ascorbic acid. Among carotenoids and alpha-tocopherol examined, serum lycopene in the high-dose beta-carotene group was significantly higher than in the placebo group at all points. No unfavorable change in carotenoids and alpha-tocopherol was observed in any group.

OBJECTIVES: Since there is a significant overlap in serum cobalamin concentrations between healthy and cobalamin-deficient individuals, we wanted to compare two different principles for use as supplementary tests to serum cobalamin concentration in patients with suspected cobalamin malabsorption and deficiency. DESIGN: Clinical study of consecutive patients. SETTING: The catchment area of Sahlgrenska University Hospital, Göteborg. SUBJECTS: A total of 112 patients with suspected cobalamin deficiency who had not previously undergone gastrointestinal surgery. INTERVENTIONS: Gastroduodenoscopy with biopsies taken from the gastric body and the duodenum, Schilling test, and measurement of serum methylmalonic acid (MMA), total homocysteine (Hcy), pepsinogens A and C, and gastrin. MAIN OUTCOME MEASURES: Number of patients with gastric body atrophy identified with the combination of MMA and Hcy, and pepsinogen A combined with pepsinogen C or gastrin. RESULTS: About 95% of the patients with severe gastric body atrophy had abnormal concentrations of serum pepsinogen A and/or gastrin or pepsinogen A/C ratio, whereas 65% had abnormal metabolite concentrations. Serum pepsinogen A combined with pepsinogen C identified 100%, and combined with gastrin 88%, of the patients with gastric body atrophy and elevated metabolite tests, and 67 and 75%, respectively, of those who had not yet developed elevated metabolite tests. CONCLUSIONS: Pepsinogen A, combined with pepsinogen C or gastrin, should be the first option in evaluating patients with suspected cobalamin deficiency who have not previously undergone gastrointestinal surgery.

Monosodium glutamate (MSG) taken per os has been found to stimulate gastric secretion provoked by pentagastrin. MSG gave rise to a marked elevation of endogenic gastrin levels both in experimental animals and atrophic gastritis patients. Thirty-six patients with secretory gastric insufficiency received MSG as an additive to their food during combined therapy of their disease. The preparation proved to be well-tolerated, good stimulant of gastric secretion, efficient in digestion improvement. MSG is recommended as an adjuvant in combined therapy of atrophic gastritis.

The development of gastric enterochromaffin-like (ECL)-cell hyperplasia in humans may be associated with extreme hypergastrinaemia, as occurs in Zollinger-Ellison syndrome (ZES) and pernicious anaemia (type A gastritis). More recently, endocrine cell hyperplasia has been found in all forms of chronic atrophic gastritis and even in cases of focal atrophy. Serum gastrin levels, non-antral gastric endocrine (argyrophil) cell growth, and the severity and type of concomitant gastritis were monitored in 66 unoperated and 8 antrectomized patients with poorly responsive peptic ulcer or reflux oesophagitis during up to 5 years' treatment with high-dose omeprazole, 40 mg daily. A small subgroup of patients (23%) had serum gastrin concentrations of more than four times the normal upper limit. These patients also had hyperplasia of the gastric argyrophil cells. More importantly, the same subgroup of patients had high-grade (atrophic) gastritis. Micronodular hyperplasia of argyrophil cells was significantly more frequent in biopsies showing atrophic gastritis (48%) than in biopsies showing only superficial gastritis (3.6%). It is concluded that, as previously demonstrated in untreated patients with gastric ulcer, the argyrophil cell hyperplasia observed during high-dose omeprazole therapy is related to the progression of chronic atrophic gastritis rather than to serum gastrin levels.

161 cases of chronic gastritis (including 59 superficial gastritis, 86 atrophic gastritis, 16 superficial gastritis combined with atrophic gastritis) typed in deficiency syndrome (including 64 Spleen-deficiency syndrome, 97 Spleen-Kidney-deficiency syndrome) were studied clinically with modern medicinal multiple-index. The gastroscope image, pathologic changes of gastric mucosa, stomach barium meal examination, gastric acid, serum gastrin, urine pepsinogen, urine 17-ketosteroid, vegetative nerve function, peripheral blood picture, etc. were selected as observation indices. The preliminary findings showed that in Spleen-deficiency patients, the superficial gastritis constituted the majority, the asthenic stomach constituted the minority, the gastric secretion and the serum gastrin were on the high side, the urine pepsinogen, the adrenocortical function and the hemoglobin were on the low side, but the white blood cell was rather normal; otherwise, in Spleen-Kidney deficiency patients, the atrophic gastritis and the asthenic stomach constituted the majority, the gastric secretion decreased, the serum gastrin level was higher, while the urine pepsinogen, the adrenocortical function, white blood cell and the hemoglobin were on the low side. It was also found that in certain same inflammation changes, the gastric secretion of the Spleen-Kidney-deficiency syndrome was markedly than that of Spleen-deficiency syndrome. With the treatment method of invigorating the Spleen and reinforcing the Spleen-Kidney, each index was relatively improved. The degree of seriousness to inflammation changes of gastric mucosa and the disturbance or imbalance of gastric secretion function were reflected from the Spleen-deficiency and the Spleen-Kidney-deficiency syndromes of chronic gastritis. It is suggested that hemopoiesis and hypothalamo-adenohypophysial-adrenal cortical axis be influenced.
