Objective To investigate and analyze the current status and challenges of infant and toddler nutritional services in urban and rural medical facilities in Sichuan Province.Methods In 2022,a questionnaire survey was conducted to collect data on infant and toddler nutritional services,including feeding guidance,physical growth assessment,and micronutrient deficiency screening,as well as information on personnel and tools in medical facilities throughout Sichuan Province.The provision of nutritional services was analyzed and the urban-rural disparities were assessed.Results A total of 2206 medical facilities(29.1%from urban areas and 70.9%from rural areas)were investigated.Only 35.8%of medical facilities provided all three types of nutritional services.Specifically,the overall service provision rates were high for feeding guidance(94.6%)and physical growth assessment(85.0%),but lower for micronutrient deficiency screening(37.4%).Rural facilities exhibited significantly lower rates than their urban counterparts for both physical growth assessment and micronutrient deficiency screening(P＜0.05).The provision rates of feeding guidance ranged from 70.6%to 93.2%,with responsive feeding guidance being the least implemented(70.6%),particularly in rural areas compared to urban areas(P＜0.05).Rates for physical growth assessment and micronutrient deficiency screening ranged from 75.3%to 81.8%and 23.6%to 30.8%,respectively,both showing lower rates in rural settings compared to urban ones(P＜0.05).Nutrition service providers were predominantly nurses(52.3%)and clinical practitioners(43.4%).The availability of dietary assessment tools ranged from 7.7%to 15.9%,significantly lower in rural areas compared to urban areas(P＜0.001),while physical measurement tools were widely available at rates of 94.6%to 98.5%.Conclusion At present,the infant and toddler nutritional service provisions of medical facilities in Sichuan Province are incomplete,particularly so in the implementation of feeding guidance,physical growth assessment,and micronutrient deficiency screening.There is a notable shortage of personnel and necessary tools,with rural areas facing more significant challenges.Enhancing the overall capacity of infant and toddler nutritional services in Sichuan Province is essential,with specific attention needed for rural healthcare settings.

Objective:To explore whether NSBB is suitable for the primary prevention of liver cirrhosis accompanied by CSPH with no or small esophageal varices.Methods:Relevant literatures were retrieved from Cochrane library, PubMed, EMBASE, SinoMed, CNKI and Wanfang databases until December 12, 2020. All randomized controlled trials (RCTs) on NSBB use for primary prevention of cirrhosis accompanied by CSPH with no or small esophageal varices were collected. The literature was strictly screened according to the established inclusion and exclusion criteria, odds ratio (OR), and 95% confidence interval (CI) combined effect size. The development of esophageal varices and the initial upper gastrointestinal bleeding were the primary outcome measures. Death (with a maximum average follow-up of about five years) and adverse events (adverse drug reactions, etc.) were the secondary outcome measures.Results:A total of 9 RCTs with 1396 cases were included. Meta-analysis results showed that, compared with placebo, NSBB significantly reduced the incidence of liver cirrhosis accompanied by CSPH with no or small esophageal varices to large esophageal varices progression ( OR=0.51, 95% CI: 0.29-0.89, P=0.02), and mortality (with maximum average follow-up of about five years) ( OR=0.64, 95% CI: 0.44-0.92, P=0.02); however, there was no statistically significant difference in the initial upper gastrointestinal bleeding rate between the two groups ( OR=0.82, 95% CI: 0.44-1.52, P=0.53). Adverse event incidence was greater in the NSBB than the placebo group ( OR=1.74, 95% CI: 1.27-2.37, P=0.0005). Conclusions:NSBB use cannot reduce the initial upper gastrointestinal bleeding rate or adverse event incidence in patients with liver cirrhosis accompanied by CSPH with no or small esophageal varices, but it can delay the progression of gastroesophageal varices and reduce patient mortality.

Background: Esophageal mucosal injury induced by gastroesophageal reflux is a key link to the development of Barrett's esophagus-associated adenocarcinoma. However, the molecular mechanism is still not elucidated. Aims: To investigate the role of differentially expressed genes (DEGs) after stimulating esophageal cells with acid and bile acid in the development of esophageal adenocarcinoma (EAC). Methods: The DEGs were obtained through bioinformatics methods after stimulating esophageal cells with low pH and deoxycholic acid, and GO, KEGG enrichment analysis were performed. Protein-protein interaction (PPI) network was performed to screen the hub genes, and their relationships with prognosis and tumor stage of EAC patients were analyzed. The role of co-expressed genes of GADD45B in EAC was also analyzed. Results: Thirty-one overlapping DEGs were obtained after stimulating esophageal cells with low pH and deoxycholic acid, which mainly enriched in the cytokine-cytokine receptor interaction, transcription factors activity, and regulation of cell proliferation and apoptotic process. High expression of GADD45B was correlated with the survival prognosis and tumor stage of EAC patients. GADD45B and its co-expressed genes were involved in the production of tumor necrosis factor. Conclusions: The high expression of GADD45B induced by acid and bile acid is correlated with the prognosis and tumor stage of EAC patients, and is a potential diagnosis and treatment target for Barrett's esophagus-associated adenocarcinoma.

Background: Aberrant Bcl-2 transcription is closely related with nodal diffuse large B-cell lymphoma (DLBCL), however, the relationship between Bcl-2 and primary gastrointestinal DLBCL (PGI-DLBCL) was not fully studied.Aims: To investigate the relationship between Bcl-2 gene amplification and protein expression and clinicopathological characteristics, immunophenotype and prognosis of PGI-DLBCL.Methods: Clinical data was collected from 136 PGI-DLBCL patients receiving surgical treatment, and a telephone interview was conducted for survival information.Bcl-2 gene amplification and protein expression in tumor tissue were determined by fluorescence in situ hybridization and immuno-histochemistry, respectively, and relationships between Bcl-2 and clinicopathological characteristics, immunophenotype and prognosis of PGI-DLBCL were analyzed.Results: Among 136 PGI-DLBCL patients, 33 (24.3%) showing gene amplification and 90 (66.2%) showing protein expression of Bcl-2;gene amplification was correlated with primary tumor location, Ann Arbor stage, serum lactate dehydrogenase level, B symptom and International Prognostic Index (IPI) score (P<0.05), while protein expression was correlated with primary tumor location and immunophenotype (P<0.05).5-year overall survival (OS) in patients positive for Bcl-2 gene amplification and patients with non-GCB immunophenotype and positive for Bcl-2 protein expression were inferior to those negative ones (41.5%vs.71.5%, P<0.05;54.6% vs.84.6%, P<0.05).In Bcl-2 gene amplification or protein expression positive patients, 5-year OS of CHOP chemotherapy was inferior to that of rituximab combined with CHOP chemotherapy (48.6%vs.80.3%, P<0.05;66.4%vs.83.4%, P<0.05).Conclusions: Detection of Bcl-2 gene amplification is useful for prediction of prognosis in PGI-DLBCL.Both patients with Bcl-2 gene amplification and non-GCB patients with Bcl-2 protein expression have a poorer prognosis.Rituximab may improve the prognosis in patients with Bcl-2 gene amplification or protein expression.

Objective To observe the clinical efficacy of abdominal acupuncture plus herbal medicine in treating chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases.Method Sixty patients with chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by abdominal acupuncture plus herbal medicine, while the control group was by herbal medicine alone. After 3 menstrual cycles, the Visual Analogue Scale (VAS) for abdominal pain and McCormack scale were observed.Result After intervention, the abdominal VAS score and McCormack score were changed significantly in both groups (P<0.01,P<0.05). After intervention, there were significant differences in comparing the VAS score and McCormack score between the two groups (P<0.01).Conclusion Abdominal acupuncture plus herbal medicine can reduce chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases.
