Mechanism of action of Xiaochaihu decoction in the treatment of hepatitis B based on network pharmacology / 临床肝胆病杂志

Objective To investigate the mechanism of action of Xiaochaihu decoction in the treatment of hepatitis B based on network pharmacology. Methods The TCMSP database was used to obtain the main chemical components and action targets of the seven traditional Chinese medicines in Xiaochaihu decoction; the GeneCards and OMIM databases were used to obtain the targets associated with hepatitis B; the STRING online platform was used to construct a PPI network of potential targets, and R language was used to perform gene ontology (GO) functional enrichment analysis and KEGG pathway analysis; Cytoscape 3.7.2 was used to construct an "active component-core target" network and perform a topology analysis of this network; AutoDock vina and related software were used to perform molecular docking and visualized analysis of the active components with high value and the core targets in the network. Results A total of 193 main chemical components (including quercetin, kaempferol, wogonin, and naringenin) and 247 related targets were screened out, among which the key targets included RELA, MAPK1, TP53, ESR1, EGFR, and AKT1. A total of 2612 enrichment items were obtained by GO functional enrichment analysis, which were mainly involved in regulating the biological processes such as cell response to chemical stress, response to drugs, oxidative stress response, and lipopolysaccharide response. A total of 174 pathways were obtained by the KEGG pathway analysis, mainly involving hepatitis B, PI3K-AKT signaling pathway, and MAPK signaling pathway. Molecular docking results showed that the main active components had strong binding force to core targets, and the protein crystal complex had a stable conformation. Conclusion This study preliminarily shows that Xiaochaihu decoction exerts a therapeutic effect on hepatitis B through multiple components, targets, and pathways.

Combined Detection of Serum MiR-221-3p and MiR-122-5p Expression in Diagnosis and Prognosis of Gastric Cancer

PURPOSE: To investigate the clinical value of serum miR-221-3p and miR-122-5p expression levels in the diagnosis and prognosis of gastric cancer. MATERIALS AND METHODS: Serum samples from 141 gastric cancer cases (gastric cancer group), 110 gastric polyps (gastric polyp group), and 75 healthy people (healthy control) were used to detect miR-221-3p and miR-122-5p expression using real-time reverse transcription polymerase chain reaction. RESULTS: Serum miR-221-3p expression was significantly higher in the gastric cancer group than in the gastric polyp group, and it was significantly lower than that before operation. The miR-221-3p expression was significantly higher in the death group than in the survival group. The proliferation and migration ability significantly increased and the apoptosis rate significantly decreased by miR-221-3p transfection in gastric cancer cells. In contrast, the function of miR-122-5p in gastric cancer cells was opposite of miR-221-3p. Serum miR-221-3p expression was negatively correlated with that of miR-122-5p in gastric cancer. Serum miR-221-3p and miR-122-5p expressions were significantly correlated with the degree of differentiation, tumor, node, metastasis stage, lymph node metastasis, and invasion depth. miR-221-3p and miR-122-5p expression levels were independent prognostic factors for postoperative gastric cancer. In the diagnosis and predicting prognosis of gastric cancer, receiver operating characteristic analysis revealed that the area under curve of combined detection of serum miR-221-3p and miR-122-5p expression had a greater diagnostic effect than either single maker. CONCLUSIONS: The miR-221-3p and miR-122-5p are involved in the development of gastric cancer, and they have important clinical values in gastric cancer diagnosis and prognosis.

The protective effect of early enteral nutrition on intestine mucosal function in acute pancreatitis / 中国基层医药

Objective To investigate the protective effect of early enteral nutrition (EN) on the function of intestinal barrier in acute pancreatitis (AP) patients.Methods From April 2014 to April 2016,a total of 81 AP patients admitted to our hospital were randomly divided into EN group (41 cases) and total parenteral nutrition (TPN) group (40 cases) by the method of opening envelop.The levels of serum albumin,inflammation cytokines and index of intestinal barrier function were compared between the two groups.Results No significant differences were found in the demographic characteristics between EN and TPN group at the 1st,3rd,7th day (all P＞0.05).Compared with TPN group,EN group showed significantly higher level of serum albumin since the 7th day (t=4.623,4.517,all P＜0.05) and significantly lower level of serum CRP since the 7th day (t=2.211,3.010,all P＜0.05) and significantly lower level of serum TNF-α since the 3rd day(t=2.095,3.364,3.249,all P＜0.05).In the aspect of intestinal barrier,compared with TPN group,the patients in EN group showed significantly lower level of serum D-lactic since the 7th day(t=3.940,2.626,all P＜0.05) and significantly lower level of serum DAO also since the 7th day(t=3.090,2.880,all P＜0.05).Conclusion EN can effectively maintain the level of serum albumin,decrease the level of serum inflammation cytokines and protect the function of intestinal mucosa barrier.

Characteristics and treatment of the complications of Crohn's disease / 中华消化外科杂志

Objective To investigate the characteristics and treatment of the complications of Crohn's disease. Methods The clinical data of 202 patients with Crohn's disease and relevant complications who were admitted to the Nanjing General Hospital of Nanjing Military Command from January 2000 to December 2007 were retrospectively analyzed. The main complications included intestinal obstruction, fistula, acute perforation,abscess, abdominal mass and et al. Results Of the 202 patients, 116 had more than two complications. Intestinal obstruction (72 patients) was the most common complication among the initial complications, and followed by fistula (31 patients), acute perforation (23 patients), abscess (22 patients), abdominal mass (22 patients),anal complications (21 patients) and gastrointestinal bleeding (11 patients). Fistula was mostly observed in patients with secondary complications during the early stage (≤three months), while obstruction (24 patients),fistula (22 patients) and obscess (11 patients) were prevalent during the mid-late stage (＞ three months). Of the 202 patients with primary complications, 170 received surgical treatment and 32 received non-surgical treatment. Of the 116 patients with secondary complications, 96 received surgical treatment and 20 received non-surgical treatment. A total of 127 patients were cured by surgical treatment, the condition of 33 patients was improved and six patients died. The condition of patients received non-surgical treatment was improved, and no patient died.Conclusions The incidence of complications of Crohn's disease is increasing steadily. Intestinal obstruction is the most common complication, and then followed by fistula. Surgery is important in the treatment of the complications of Crohn's disease.
