Background and purpose:Colorectal cancer (CRC) is a malignancy which is the third incidence and the fourth mortality in the worldwide. The main reason for the development of CRC is that the changes of genetic and epigenetic causes the tumor suppressor gene methylation silencing. This study aimed to investigate the plasma and stool GATA5 gene promoter methylation was detected in clinical diagnosis of CRC. Methods: To collect the paired plasma and stool specimens of 34 cases of healthy and 43 cases of patients with CRC. Methylation speciifc PCR (MSP) was respectively detected the GATA5 gene methylation levels of GATA5 gene in plasma and stool. And then separately analyzed their correlations with clinical and pathological parameters in gastric carcinoma. Results: The result of MSP showed that GATA5 gene promoter methylation rates in plasma and stool of CRC patients were 60.74%, 76.60%, respectively, were higher than those of healthy persons (6.47%, 32.35%). And the differences were statistically signiifcant (P=0.006 7, P=0.000 2, respectively). GATA5 gene methylation rates in plasma of CRC patients were closely related to clinical stage (P=0.000 5) and lymph node metastasis(P=0.020), while GATA5 gene methylation rates in stool of CRC patients had no signiifcant with clinical and pathological parameters. Conclusion:Detection of faecal GATA5 gene methylation level and supplemented plasma GATA5 gene methylation level can become a simple, non-invasive, sensitive and speciifc method for clinical diagnosis of CRC.

Objective:To investigate the diagnostic value of the promoter methylation of plasma RNF180 gene and its protein ex-pression for the detection of gastric cancer. Methods:Methylation-specific polymerase-chain reaction (MSP) and enzyme-linked immu-no-sorbent assay (ELISA) were performed to detect DNA methylation and protein expression of the RNF180 gene, respectively. The correlations of DNA methylation and protein expression of the RNF180 gene with the clinico-pathological parameters of gastric carcino-ma were then separately analyzed. Results:MSP showed that the methylation rates of the RNF180 gene were 62.75%and 21.88%in the plasma of patients with gastric carcinoma and healthy volunteers, respectively;this result indicated that the two groups significantly differed (P<0.01). The methylation of the RNF180 gene was associated with tumor size, clinical stage, tumor differentiation, lymph node metastasis, and distant metastasis (P<0.05). ELISA results showed that the protein expression of the RNF180 gene [(23.22 ± 1.36)μg/mL] was significantly lower (P<0.01) in the plasma of patients with gastric carcinoma than in the plasma of healthy volunteers [(34.25 ± 2.44)μg/mL]. However, the protein expression of the RNF180 gene was not associated with clinicopathological parameters (P>0.05). Conclusion:The RNF180 gene is expressed at a hypermethylation rate, and the corresponding protein expression level is de-creased in the plasma of individuals with gastric carcinoma. Therefore, RNF180 gene methylation in plasma could be applied to detect microinvasion for the clinical diagnosis of gastric cancer.

Objective To summarize the experience of multi-disciplinary team(MDT)in the pediatric department of Qujing Maternal and Child Health Hospital,and to evaluate the effectiveness of MDT on neonatal brain injury.Methods The clinical data of children with brain injury and treated in the pediatrics department of Qujing Maternal and Child Health Hospital from November 2019 to April 2023 were collected.The children with brain injury and treated from October 2019 to June 2020 were regarded as the non-MDT group,and the children with brain injury and treated from July 2020 to April 2023 were regarded as the MDT group for comparative analysis.Chi-square test/t-test was used to compare and analyze the clinical data of the two groups.Results Among the 890 cases of pediatric brain injury,there were 519 males and 371 females.The median and quartiles of the age distribution for the two groups were as follows:MDT group 2.00(0.82,5.00)years and non-MDT group 1.00(1.00,4.00)years.Craniocerebral injury was the main type of brain injury in both groups,in addition,among children with craniocerebral injury and intracranial hemorrhage,the cure rate of MDT group was higher than that of non-MDT group,and the difference was statistically significant(P<0.05).Among the 405 children in MDT group,154(38.0%)underwent the surgery,while among the 485 children in non-MDT group,121(24.9%)underwent the surgery.The difference was statistically significant(P<0.05).23.2% of children in MDT group were in critical condition during the hospitalization,which was significantly lower than that in non-MDT group(30.5%),and the difference was statistically significant(P<0.05).The unhealed rate of MDT group(2.0%)was also significantly lower than that of non-MDT group(5.6%),the cure rate of MDT group(40.5%)was significantly higher than that of non-MDT group(34.4%),and there was a statistically significant difference(P<0.05).The expense of treatment,medicine and sanitary materials in MDT group were lower than those in non-MDT group,and the differences were statistically significant(P<0.05).The multivariate Logistic regression model analysis of the cure rate of children with brain injury showed that the MDT model could effectively improve the cure rate of children with brain injury(RR = 1.513,95% CI = 1.134-2.020).The results of multiple linear regression model analysis showed that there was no statistical difference in the effect of MDT on the actual hospitalization days of children(P>0.05).Conclusion Using MDT model to diagnose and treat children with brain injury is helpful to improve the cure rate,reduce the risk of children's disease aggravation,and achieve the significant therapeutic effects in children with brain injury.MDT model is worth popularizing and applying in children with brain injury.

Objective:To investigate the clinical, endoscopic and pathological features, and treatment and prognosis of gastric adenocarcinoma of fundic gland type of chief cell predominant type (GA-FG-CCP).Methods:Data of 40 GA-FG-CCP patients with 41 lesions diagnosed by histopathology at Ningbo Medical Center Lihuili Hospital and Shanghai East Hospital from January 2018 to May 2023 were collected. Their clinical and endoscopic features, pathological features, immunohistochemical results, endoscopic treatment, and prognosis were analyzed.Results:Among the 40 GA-FG-CCP patients, there were 15 males and 25 females, and the mean age was 60.03 years. Most of them had no obvious clinical symptoms or family history of tumor. Except one case, others had no helicobacter pylori infection. The endoscopic features of white light observation were: ① the main location was the upper part of the gastric body (63.41%, 26/41); ② faded or whitish mucosal surface (56.10%, 23/41); ③ dilated vessels with branch architecture (78.05%, 32/41); ④ no background mucosal atrophy (100.00%, 41/41). The features of magnifying endoscopy with narrow band imaging (ME-NBI) were: ① no obvious demarcation line (85.37%, 35/41); ② enlargement of the crypt opening (87.80%, 36/41); ③ widening of the intervening part (92.68%, 38/41); ④ lack of irregular microvascular pattern (95.12%, 39/41). All patients were confirmed gastric adenocarcinoma of the fundic gland by biopsy. The glands showed a low degree of dysplasia, similar to the differentiation of chief cell predominant pattern, also with scattered parietal cells, forming irregular and anastomosing cords. In the 40 patients, 20 did not receive endoscopic therapy. Twelve out of 21 lesions in 20 cases treated with endoscopic resection infiltrated into the submucosa (20-520 μm), 9 cases were intramucosal carcinoma. There was no lymphatic or venous infiltration, and horizontal and vertical margins were negative. Immunohistochemical staining results showed that the tumor was postive for pepsinogen-Ⅰ and MUC 6, with scattered postive for H +-K +-ATPase, but negative for MUC5AC, MUC2 and CD10, and the Ki-67 labeling index was low. No patients had recurrence or metastasis during mean follow-up of 15.85 months. Conclusion:GA-FG-CCP is rare and very well differentiated. Its clinical symptoms are not obvious, but there is endoscopic characteristics. The detection rate of GA-FG-CCP can be improved by white light and ME-NBI, and the diagnosis can be confirmed by pathology and immunohistochemical staining.

Objective:To explore regulatory effects of short-chain fatty acids (SCFA) on hypoxia-induced oxidative stress and activation of pancreatic stellate cells (PSCs) .Methods:PSCs were cultured in normoxia or hypoxia conditions to establish normoxia or hypoxia group. PSCs were pre-treated with SCFA working solution (10 mmol/L sodium acetate, 0.5 mmol/L sodium propionate and 0.5 mmol/L sodium butyrate), and then cultured in hypoxia conditions to establish the hypoxia-SCFA group. PSCs pre-treated by normal saline was set as the hypoxia-control group. The relative growth viability of the cells was detected by the CCK-8 assay. Relative levels of reactive oxygen species (ROS) were detected by DCFH-DA fluorescence probe method. The mitochondrial membrane potential was detected by JC-1 fluorescence probe. Protein expression of cyclin-associated marker cyclin A and cyclin D, hypoxic marker HIF1α, activation marker α-SMA, and antioxidant marker NRF2 and HO-1 was detected by western blotting.Results:The relative viability of PSCs in hypoxia group was significantly higher than that in normoxia group at 48 h (1.23±0.05 vs 0.99±0.04), but the relative viability of hypoxia-SCFA group was significantly lower than that of the hypoxic-control group at both 36 h and 48 h (0.69±0.01 vs 0.86±0.03, 0.86±0.02 vs 1.25±0.05). The relative level of ROS was significantly higher in hypoxia group than normoxia group (1.74±0.11 vs 1.00±0.10). The relative level of ROS was significantly lower in the hypoxia-SCFA group than the hypoxia-control group (1.39±0.14 vs 1.66±0.11). The fluorescence signals of JC-1 polymer in hypoxia group were significantly higher than those in normoxia group (1.36±0.05 vs 1.00±0.11), whereas the fluorescence signals of JC-1 polymer were significantly lower in hypoxia-SCFA group than in hypoxia-control group (1.11±0.03 vs 1.32±0.06). The expression of cyclin A, cyclin D, HIF1α, α-SMA, NRF2, and HO-1 was significantly higher in hypoxia group than those in normoxia group (1.19±0.01 vs 0.63±0.02, 0.93±0.02 vs 0.83±0.03, 1.18±0.07 vs 0.41±0.02, 1.19±0.14 vs 0.66±0.04, 1.22±0.11 vs 0.61±0.04, 1.28±0.12 vs 0.68±0.02), but the expression of cyclin A, cyclin D, α-SMA, NRF2, and HO-1 in Hypoxia-SCFA group was significantly lower than those in hypoxia-control group (0.79±0.04 vs 1.15±0.03, 0.88±0.01 vs 0.95±0.03, 0.87±0.01 vs 1.18±0.05, 0.84±0.01 vs 1.22±0.04, and 0.92±0.02 vs 1.27±0.06). All these differences were statistically significant (all P values <0.05) . Conclusions:SCFA significantly improves the oxidative stress state of PSCs under hypoxic conditions, maintains the stability of mitochondrial membrane potential, and inhibites hypoxia-induced activation of PSCs.
