Objective To study the expression of basic ifbroblast grouth factor (bFGF) and transforming growth factorβ1 (TGF-β1) in different stages of myocardial ifbrosis (CFs). Methods CFs of neonatal Sprague-Dawley rats were isolated with the method of trypsin digestion and differential anchoring velocity, then cultured in vitro. The generation 2-4 of CFs were used for the experiment and randomly divided into 2 groups:the control group were cultured without AngII , and the test group were cultured with AngII 10-6 mol/L. The test group were cultured for 12, 24, 48, and 72 h respectively, and then the synthesis of col agen were measured by ELISA, the bFGF, TGF-β1-mRNA expression was measured by RT-PCR, and the bFGF and TGF-β1 protein expression was measured by western blot analyses. Results Compared with those of control group, the expressions of bFGF and TGF-β1 both in gene and in protein in the test groups increased gradual y with the timing (P?0.01). Correlation analysis found that the expression of bFGF mRNA and protein were positively associated with TGF-β1 mRNA and protein (r?=?0.967, 0.947, P?<0?.05), and both bFGF and TGF-β1 were positively associated with the supernatant col agen. (r?=?0.932, 0.881, 0.930, 0.896, P?<0?.05). Conclusion bFGF and TGF-β1 may be involved in the occurrence and development of myocardial ifbrosis.

Objective To investigate the efficacy of different courses of saccharomyces boulardii powder combined with triple therapy in eradicating helicobacter pylori(Hp)in children.Methods A total of 135 children with Hp-related gastritis who received initial treatment in the Department of Pediatrics,Affiliated Hospital of Xuzhou Medical University from October 2021 to June 2022 were selected and divided into three groups according to random number table method:group A,group B and group C,with 45 cases in each group.Group A:triple therapy(omeprazole + clarithromycin + amoxicillin)for 14 days;group B and group C:on the basis of triple therapy,saccharomyces boulardii powder was added from the first day of treatment for 2 weeks and 4 weeks,respectively.The adverse reactions during treatment were recorded,the levels of serum pepsinogen Ⅰ(PGⅠ)and pepsinogen Ⅱ(PGⅡ),clinical efficacy and Hp eradica-tion rate were observed 4 weeks after the end of treatment.Results The levels of serum PGⅠ and PGⅡ in the three groups after treat-ment were significantly lower than those before treatment(P<0.05),the levels of serum PGⅠ and PGⅡ in group B and group C after treatment were lower than those in group A(P<0.05),and the levels of serum PGⅠ and PGⅡ in group B were lower than those in group C after treatment(P<0.05).The clinical effective rates of group B(93.0%)and group C(90.4%)were higher than those of group A(62.5%)(P<0.05).The clinical effective rate of group B was higher than that of group C(P>0.05).The Hp eradication rate of group B and group C was significantly higher than that of group A(P<0.05),and the Hp eradication rate of group B was higher than that of group C(P>0.05).The incidence of diarrhea and loss of appetite in group B and group C were lower than those in group A(P<0.05);the incidence of diarrhea and loss of appetite in group B was lower than that in group C(P<0.05).There was no signifi-cant difference in the incidence of abdominal pain,nausea and vomiting among the three groups(P>0.05).Conclusion Saccharomy-ces boulardii decoction combined with triple therapy for 2 or 4 weeks can effectively regulate PG level,improve the eradication rate of Hp,and reduce the incidence of adverse reactions.It is suggested that 2 weeks is the best course of treatment.

Objective:To explore the expression of the nucleotide-binding oligomerization domain-like receptor containing pyrin domain protein 6 (NLR family,pyrin domain containing 6,NLRP6) in the gastric tissue and gastric juice of children with chronic non-atrophic gastritis (CNG), and to analyze the influence of Helicobacter pylori (Hp) infection on the expression of NLRP6.Methods:A case-control study was conducted to select 120 CNG patients in pediatrics of Department of Pediatrics, The Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021. According to pathological diagnosis, endoscopic gastric mucosal damage and Hp infection, they were divided into 4 groups: mild CNG group Hp negative, Moderate to severe CNG group Hp negative, Mild CNG group Hp positive, Moderate to severe CNG group Hp positive. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of NLRP6 in the four groups of gastric tissue and gastric juice, and Western blot was used to detect the expression of NLRP6 in the gastric tissue of the 4 groups, and the significance of expression in CNG of children is analyzed. Independent sample t-test was used to compare the mean between the two groups. One way ANOVA was used to compare the mean of multiple groups of samples, and LSD t-test was used for pairwise comparison. Comparison between count data groups χ 2 inspection. Results:The positive rate of Hp in the moderate to severe chronic non-atrophic gastritis group was 62.96% (34/54) higher than that in the mild chronic non-atrophic gastritis group 37.04% (20/54), and the difference was statistically significant (χ 2=18.32, P<0.001). Under the same Hp conditions, the expression of NLRP6 in the mild chronic non-atrophic gastritis group (Hp negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp positive mild CNG: Gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L was higher than the moderate to severe chronic non-atrophic gastritis group (Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L; Hp positive Moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under Hp negative, mild compared with moderate to severe CNG: gastric tissue P=0.035; gastric juice P=0.046; Under Hp positive, mild compared with moderate to severe CNG: gastric tissue P=0.010;gastric juice P=0.002); in the same degree of gastric mucosal injury, NLRP6 expression in Hp-negative group (Hp-negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L higher than the positive group (Hp positive mild CNG: gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L; Hp positive moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under mild CNG, Hp negative is compared with positive: Gastric tissue P=0.005; gastric juice P=0.023; under moderate to severe CNG, negative versus positive: gastric tissue P=0.004; gastric juice P=0.003). Conclusion:Under the same Hp conditions, the more severe the gastric mucosal damage, the lower the NLRP6; under the same degree of mucosal damage, the expression level of NLRP6 in the Hp-negative group was significantly higher than that of the Hp-positive group. It is suggested that NLRP6 plays a role in inhibiting inflammation in chronic gastritis, maintaining the integrity of epithelial cells, and Hp can inhibit the expression of NLRP6.
