Clinical observation of magnesium aluminum carbonate combined with rabeprazole-based triple therapy in the treatment of helicobacter pylori-positive gastric ulcer associated with hemorrhage.

Objectives: To evaluate the clinical effect of magnesium aluminum carbonate combined with rabeprazole-based triple therapy in the treatment of patients with Helicobacter pylori-positive gastric ulcer associated with hemorrhage. Methods: A total of 80 patients with Helicobacter pylori-positive gastric ulcer associated with hemorrhage admitted to the Baoding First Central Hospital from January 2019 to December 2020 were selected and randomly divided into two groups, with 40 cases in each group. The control group were given rabeprazole-based triple therapy, while the experimental group were treated with magnesium aluminum carbonate on the basis of the control group. The changes of symptoms and signs such as abdominal pain, abdominal distension, nausea, vomiting and hematochezia were compared between the two groups before and after treatment. Serological changes of the gastric mucosal microenvironment, such as the serum levels of extracellular regulatory protein kinase (ERK), superoxide dismutase (SOD) and epidermal growth factor receptor (EGFR), were compared between the two groups. Moreover, the differences in the results of gastroscopy between the two groups before and after treatment were compared and analyzed. Results: The scores of gastrointestinal symptoms in the experimental group after treatment were significantly improved compared with the control group (p=0.00). The levels of ERK and EGFR in the experimental group were significantly lower than those in the control group (ERK, p=0.01; EGRF, p=0.00), while the level of SOD was significantly increased (p=0.02). After treatment, the total effective rate of ulcer healing in the experimental group was 82.5%, which was significantly better than 60% in the control group (p=0.03). After treatment, moderate to severe gastric mucosal inflammation in the experimental group decreased to 10%, significantly better than that in the control group (decreased to 30%) (p=0.03). Conclusion: Magnesium aluminum carbonate combined with rabeprazole-based triple therapy is preferred for the treatment of patients with Helicobacter pylori-positive gastric ulcer associated with hemorrhage. With such a highly effective treatment regimen, the internal environment and blood supply of gastric mucosal cells can be significantly improved, gastric mucosal inflammation and gastrointestinal symptoms can be ameliorated, and the healing of ulcer surfaces can be accelerated.

Clinical effects of Apatinib combined with DOS neoadjuvant chemotherapy regimen in neoadjuvant chemotherapy for LAGC.

OBJECTIVE: To evaluate the clinical effects of apatinib combined with DOS regimen in the neoadjuvant chemotherapy for locally advanced gastric cancer (LAGC). METHODS: Eighty patients with LAGC admitted to Baoding first Central Hospital from January 2018 to October 2020 were randomly divided into two groups (n=40, respectively). The control group received DOS chemotherapy regimen alone. The experiment group additionally orally took apatinib mesylate tablets. The changes in CEA, CA19-9 and other tumor markers, RO resection rate, incidence of operative complications, adverse reactions, and other indicators were compared between the two groups. RESULTS: The overall response rate (ORR) of the experimental group was 72.5%, which was significantly better than that of the control group (50%) (p=0.03). After the treatment, the CEA and CA19-9 in the experiment group were significantly lower than those in the control group (p=0.00). The Ro resection rate was 77.5% in the experiment group and 57.5% in the control group (p=0.03). The operation time was shortened and amount of bleeding decreased in the experiment group, and the differences were statistically significant (p=0.00). The incidence of surgical complications in the experimental group was 17.5%, significantly lower than that in the control group (37.5%) (p=0.04). CONCLUSION: Apatinib combined with DOS regimen is effective for patients with LAGC without significantly increasing adverse reactions. Meanwhile, tumor markers are reduced significantly. Besides, the Ro resection rate and the incidence of operative complications are obviously superior to the DOS neoadjuvant chemotherapy regimen alone.

Analysis of clinical characteristics of 2243 with positive anti-gastric parietal cell antibody.

BACKGROUND: To facilitate the early detection of chronic diseases, we analyzed the clinical characteristics of anti-gastric parietal cell antibody (PCA)-positive population, revealed the early characteristics of the population. METHODS: According to the retrospective analysis, current situation investigation and comparative analysis of the clinical characteristics and medical history of the subjects, the comparison between the groups was performed. RESULT: (a) The positive rate of PCA detection in department of gastroenterology in our hospital was 35.80%. Among the individuals who underwent PCA, esophagogastroduodenoscopy (EGD) and pathological examination at the same time, 33.59% of the patients with PCA positive were diagnosed as atrophic gastritis by gastroscopy, which was much higher than 9.09% of the patients with PCA negative. (b) The incidence of gastroesophageal reflux, hypertension, ischemic heart disease (IHD) and cerebral ischemia in PCA-positive population were 65.45%, 81.63%, 15.43%, and 31.61%, respectively, which were significantly higher than those in the control group. (c) The incidence rates of decreased red blood cells (RBC) and increased homocysteine (HCY) in laboratory-related tests were 38.30% and 69.15%, respectively, which were much higher than those in control group. CONCLUSION: PCA has predictive value for a variety of chronic diseases and timely detection is of great significance.

[Cut-off value of white blood cell count in the diagnosis of early-onset sepsis in neonates].

OBJECTIVE: To study the clinical significance and cut-off value of white blood cell (WBC) count in the diagnosis of early-onset sepsis (EOS) in neonates. METHODS: A retrospective analysis was performed on 306 neonates with EOS who were admitted from January 2019 to March 2020. A total of 580 children without infection who were admitted during the same period of time were enrolled as the control group. General status and WBC count were compared between the two groups. The diagnostic value of WBC count was analyzed based on the diagnostic and therapeutic protocol of neonatal sepsis in 2003 (referred to as the 2003 diagnostic and therapeutic protocol) and the expert consensus on the diagnosis and treatment of neonatal sepsis (2019 edition) (referred to as the 2019 expert consensus). RESULTS: According to the two different diagnosis and treatment protocols, the statistical analysis showed that WBC count had a relatively positive rate (51.3% and 32.0% respectively) but a relatively high specificity (93.3% and 98.6% respectively). The receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve of WBC count in the 2003 diagnostic and therapeutic protocol was larger than that in the 2019 expert consensus (P<0.05). CONCLUSIONS: The cut-off value of WBC ≥25×109/L in the 2003 diagnostic and therapeutic protocol is more reasonable in the diagnosis of EOS.

Development and validation of a prediction rule for estimating gastric cancer risk in the Chinese high-risk population: a nationwide multicentre study.

OBJECTIVE: To develop a gastric cancer (GC) risk prediction rule as an initial prescreening tool to identify individuals with a high risk prior to gastroscopy. DESIGN: This was a nationwide multicentre cross-sectional study. Individuals aged 40-80 years who went to hospitals for a GC screening gastroscopy were recruited. Serum pepsinogen (PG) I, PG II, gastrin-17 (G-17) and anti-Helicobacter pylori IgG antibody concentrations were tested prior to endoscopy. Eligible participants (n=14 929) were randomly assigned into the derivation and validation cohorts, with a ratio of 2:1. Risk factors for GC were identified by univariate and multivariate analyses and an optimal prediction rule was then settled. RESULTS: The novel GC risk prediction rule comprised seven variables (age, sex, PG I/II ratio, G-17 level, H. pylori infection, pickled food and fried food), with scores ranging from 0 to 25. The observed prevalence rates of GC in the derivation cohort at low-risk (≤11), medium-risk (12-16) or high-risk (17-25) group were 1.2%, 4.4% and 12.3%, respectively (p<0.001).When gastroscopy was used for individuals with medium risk and high risk, 70.8% of total GC cases and 70.3% of early GC cases were detected. While endoscopy requirements could be reduced by 66.7% according to the low-risk proportion. The prediction rule owns a good discrimination, with an area under curve of 0.76, or calibration (p<0.001). CONCLUSIONS: The developed and validated prediction rule showed good performance on identifying individuals at a higher risk in a Chinese high-risk population. Future studies are needed to validate its efficacy in a larger population.
