ObjectiveTo evaluate the value of omega-3 fish oil fat emulsion in parenteral nutrition support after radical resection of gastric cancer patients.MethodsThe clinical data of 80 patients in Tongling Peopl’s Hospital undergoing radical resection of gastric cancer from March 2018 to September 2019 were enrolled by retrospective method. Of them, 40 patients were treated with routine parenteral nutrition (control group) and 40 patients were treated with extra 100 mL omega-3 fish oil fat emulsion after operation (observation group). Nutritional and stress indicators included blood total albumin (TP), albumin (ALB), c-reactive protein (CRP), and procalcitonin (PCT) on one day before operation, and 1st, 3rd, and 7th day after operation were collected. The collected indexes of liver function included blood cholesterol (CHO), triglyceride (TG), total bilirubin (TBIL), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma glutamyl transpeptidase (γ-GT) on one day before operation, and 3rd and 7th days after operation.Results① Nutritional indicator. There was no significant differences in TP and ALB levels between the two groups on one day before operation, and on the 1st, 3rd, and 7th day after operation (P>0.05). In the same group compared with one day before operation, the average TP level of the control group and the observation group decreased on the 1st, 3rd, and 7th day after operation (P<0.05), and in the control group and the observation group, the ALB level decreased on the 1st day after operation (P<0.05), and increased on the 7th day after operation (P<0.05). ② Stress index. There was no significant difference in CRP and PCT levels between the two groups on one day before and one day after operation (P>0.05), and the CRP and PCT levels in the observation group were lower than those in the control group on the 3rd day and 7th day after operation (P<0.05). Compared with the CRP and PCT levels on the one day before operation, the average CRP and PCT levels in the observation group and the control group increased on the 1st, 3rd, and 7th day after operation (P<0.05). ③ Liver function index. There was no significant differences in CHO, TG, and γ-GT levels between the two groups on one day before operation and the 3rd day after operation (P>0.05), but the above indexes of observation group were lower on the 7th day after operation than those of the control group (P<0.05). There was no significant differences on TBIL, ALT, and ALP levels between the postoperative observation group and the control group (P>0.05). Compared with one day before operation in the same group, there was no significant difference on CHO and ALP levels on 3rd and 7th day after operation in both the observation group and control group (P>0.05). There was no significant differences in TG and TBIL levels in the observation group on 3rd and 7th day after operation (P>0.05), but the TG and TBIL levels in the control group were increased on 7th after operation (P<0.05), and the ALT and γ-GT levels in the observation group and the control group on 7th day after operation were increased in the same group compared with one day before operation (P<0.05).ConclusionParenteral nutrition with omega-3 fish oil fat emulsion do not improve the recent postoperative nutritional status, but reduce the inflammatory stress response and protecte liver function in patients with gastric cancer after operation.
ObjectiveTo study value of long noncoding RNA H19 and HOTTIP in plasma in predicting efficacy of neoadjuvant chemotherapy (NAC) for resectable locally advanced gastric cancer. MethodsForty patients with T3–4aN+M0 gastric cancer and 40 patients with benign gastric diseases treated in the Yantai Yuhuangding Hospital Affiliated to Qingdao University from August 2020 to May 2021 were prospectively included. The expressions of H19 and HOTTIP in the plasma of gastric cancer and benign gastric diseases patients without any treatment after admission were detected before treatment (CAPEOX regimen was used in the patients with gastric cancer), then which were detected after 2 NAC courses for patients with gastric cancer. Meanwhile, some clinical items were detected and the efficacy of NAC was evaluated. The complete remission (CR) and partial remission (PR) were classified as objective remission, CR, PR, and disease stability were classified as disease control. The expressions of H19 and HOTTIP between the different patients were compared and the receiver operating characteristic (ROC) curve was used to evaluate their values in the diagnosis of resectable locally advanced gastric cancer. ResultsThere were 13 cases of T downstaging and 27 cases of T non-downstaging and 25 cases of objective remission and 35 disease control after NAC. The median relative expression levels of H19 and HOTTIP before NAC in the patients with gastric cancer were higher than those in the patients with benign gastric diseases (H19: 1.42 versus 0.98, Z=–3.835, P<0.001; HOTTIP: 2.15 versus 1.04, Z=–5.062, P<0.001), and which were in the patients with T downstaging and disease control were lower than those in the patients with T non-downstaging and 5 cases of disease progression (For T staging, H19: 1.12 versus 1.54, Z=–2.960, P=0.002; HOTTIP: 1.49 versus 2.30, Z=–2.310, P=0.019. For efficacy of NAC, H19: 1.39 versus 2.48, Z=–3.211, P<0.001; HOTTIP: 1.96 versus 3.25, Z=–2.393, P=0.014). The median relative expressions of H19 and HOTTIP after NAC were lower than those before NAC in the patients with gastric cancer (H19: 1.12 versus 1.42, Z=–3.965, P<0.001; HOTTIP: 1.30 versus 2.15, Z=–4.839, P<0.001). There were no significant differences in the changes of H19 and HOTTIP before and after NAC between the patients with T downstaging and T non-downstaging, and between disease control and disease progression (P>0.05). The areas of ROC curve of H19, HOTTIP, and combination of H19 and HOTTIP in diagnosis of resectable locally advanced gastric cancer were higher than 0.7. ConclusionsLncRNA H19 and HOTTIP might be potential tumor markers in gastric cancer, and their diagnostic values for resectable locally advanced gastric cancer are higher. Gastric cancer patients with low expressions of H19 and HOTTIP in plasma might be more sensitive to NAC.
ObjectiveTo evaluate the therapeutic effect and adverse reaction of paclitaxel liposome combined with continuous infusion of large-dose 5-fluorouracil(5-fu) in treatment for advance gastric cancer(AGC). MethodsFrom May 2009 to August 2012, 63 consecutive patients with AGC in this hospital were enrolled in this study. All the patients were given chemotherapy including paclitaxel liposome and continuous infusion of large-dose(2.5 g/m2) 5-fu. The efficacy and toxicity of this regimen were observed. ResultsThere was no patient who could not tolerate adverse reaction related to such regimen. Five cases achieved complete response and 31 cases achieved partial response, the overall response rate was 57.1%(36/63). Hematologic toxicity included gradeⅢ/Ⅳleucopenia 8 cases(12.7%) and neutropenia 10 cases(15.9%), while there was no occurrence of gradeⅢ/Ⅳanemia or thrombopenia. Non-hematologic toxicity was fairly mild. ConclusionsPaclitaxel liposome is safe, well tolerated, highly targeted, and has long duration of effect. Paclitaxel liposome combined with continuous infusion of large-dose 5-fu is safe and effective in treatment for patients with AGC.
ObjectiveTo systematically review the role and potential clinical value of nicotinamide N-methyltransferase (NNMT) in gastric cancer, aiming to provide new insights for diagnosis, treatment, and prognosis of gastric cancer. MethodsRelevant literature from recent years on the involvement of NNMT in gastric cancer was thoroughly analyzed. The review focuses on the mechanisms by which NNMT influences cell proliferation, invasion, migration, and metabolic reprogramming in gastric cancer. Additionally, the study explores the potential of NNMT as a diagnostic and therapeutic target. ResultsNNMT was significantly overexpressed in gastric cancer tissues and was closely associated with tumor progression. It promoted malignant behaviors through various pathways, including metabolic regulation, enhancement of cancer cell proliferation and invasion, and alteration of the tumor microenvironment. Furthermore, NNMT played a crucial role in modulating host immune responses, which might impact the clinical prognosis of gastric cancer patients. ConclusionsNNMT exhibits significant biological functions in the development and progression of gastric cancer. As a potential biomarker and therapeutic target, it holds promising clinical value in the diagnosis and targeted treatment of gastric cancer, providing new strategies and evidence for precision therapy and prognosis assessment.
ObjectiveTo explore the influence of different radiation doses of 125Ⅰseed on human poorly differentiated gastric cancer cells (BGC823). MethodsSixty four male nude mice of BLAB nu/nu inoculated with human poorly differentiated gastric cancer cells (BGC823) were took as animal models. When tumors of nude mice grew to 0.7-1.2 cm, the nude mice were randomly divided into blank control group, low dose group, middle dose group, and high dose group (n=16). The tumors of nude mice in blank control group were implanted with blank seed, but tumors of nude mice in low dose group, middle dose group, and high dose group were implanted with 125Ⅰseed (the radiation doses of 3 groups were 1.48×10-7 Bq, 2.22×10-7 Bq, and 2.96×10-7 Bq respectively). Four nude mice of 4 groups were randomly collected to measure the tumor volume and weight before implantation, and on 7, 14, 21, and 28 days after implantation, but apoptosis rates and expression levels of cyclinE mRNA were measured on 14 days and 28 days after implantation, by using flow cytometer and semi quantitative RT-PCR method respectively. Results①Except for the blank control group, the tumor volume and weight decreased over time in low dose group, middle dose group, and high dose group. The tumor volume and weight in blank control group were higher than those of other 3 groups on 7, 14, 21, and 28 days after implantation (P < 0.05);in addition, on 28 days after implantation, tumor volume and weight in low dose group were lower than those of middle dose group and high dose group (P < 0.05).②On 14 days and 28 days after implantation, the apoptosis rates of blank control group were lower than those of other 3 groups (P < 0.05), but expression levels of cyclinE mRNA were all higher than those of other 3 groups (P < 0.05). In addition, on 28 days after implantation, apoptosis rate of low dose group was higher than both of middle dose group and high dose group (P < 0.05), but expression level of cyclinE mRNA was lower (P < 0.05). Compared with 14 days in the same group, except for the blank control group (P > 0.05), the apoptosis rates in other 3 groups on 28 days were higher (P < 0.05), with the lower expression levels of cyclinE mRNA (P < 0.05). Conclusions125Ⅰseed in organizational implantation can effectively inhibit the expression of cyclinE mRNA and the growth of human poorly differentiated gastric cancer tissue. Compared with doses of 2.22×10-7 Bq and 2.96×10-7 Bq of 125Ⅰ, low dose (1.48×10-7 Bq) contributes to the apoptosis of human poorly differentiated gastric cancer cells (BGC823).

Objective To investigate the correlation between nutrition related blood biochemical indexes levels and Patient-Generated Subjective Global Assessment (PG-SGA) in preoperative nutritional assessment of patients with gastric cancer. Methods One hundred and seventeen gastric cancer patients who underwent surgery were enrolled in this study by the Department of Gastrointestinal Surgery of West China Hospital. Nutritional status of each patient was evaluated by PG-SGA, in the meantime, nutrition related blood biochemical indexes levels such as transferrin (TRF), prealbumin (PA), albumin (Alb), and hemoglobin (HGB) were measured by analysis of fasting venous blood, then take correlation analysis on the result. Results Eighty cases (68.4%) were in malnutrition (PG-SGA score≥4). The TRF, PA, Alb, and HGB in malnutrition patients were lower than those in non-malnutrition patients (PG-SGA score<4, n=37, P<0.05). The TRF, PA, Alb, and HGB levels of gastric cancer patients had significant negtive correlation with PG-SGA score, the correlation coefficients was –0.629, –0.545, –0.418, and –0.235, respectively (P<0.05). When the PG-SGA score was greater than or equal to 4 points, the optimum cutoff value for TRF, PA, Alb, and HGB was 2.31 g/L, 190.50 mg/L, 38.65 g/L, and 100.50 g/L, respectively (P<0.05). Conclusions The incidence of malnutrition is high in gastric cancer patients preoperatively. The TRF, PA, Alb, and HGB are significantly decreased in the patients with malnutrition, and these indicators has significant negtive correlation with PG-SGA score. The current study indicated that a gastric cancer patient might be in malnutrition when the biochemical levels are less than or equal to TRF 2.31 g/L, PA 190.50 mg/L, Alb 38.65 g/L, HGB 100.50 g/L, and sufficient attention should be paid when any of these occasions appear clinically. The combination of PG-SGA score and nutrition related blood biochemical indexes levels could provide a more accurate assessment of preoperative nutritional status, and the evidence of nutritional intervention for patients with gastric cancer.
Objective To detect expression of miR-106a-5p in gastric cancer cells and gastric cancer tissue, and to analyze relationship between it’s expression with clinicopathologic characteristics, and in addition, to analyze its target genes and enriched pathway with bioinformatics method. Methods The expressions of miR-106a-5p in the different differentiation of gastric cancer cells AGS (well differentiation), MKN-28 (middle differentiation), HGC-27 (undifferentiation), MGC-803 (low differentiation), BGC-823 (low differentiation), MKN-45 (middle differentiation) and SGC-7901 (middle differentiation), the normal gastric mucosal epithelial cells GES-1, and the gastric cancer tissue and the corresponding adjacent tissue were detected by the real-time fluorescent quantitative PCR. Furthermore, the target genes of miR-106a-5p were predicted by using more than three softwares affiliated to mirWALK web database and the signal pathways of target genes were enriched by DAVID 6.7 software. Results The expressions of miR-106a-5p in the different differentiation degree of the gastric cancer cells (AGS, SGC-7901, MKN-45, MGC-803, BGC-823, and HGC-27) were up-regulated except the MKN-28 cell line as compared with the normal gastric mucosa cell line GES-1 (P<0.010 orP<0.001), and the expression of miR-106a-5p in the gastric cancer tissue was also up-regulated as compared with the corresponding adjacent tissue, the expression of miR-106a-5p in the gastric cancer tissue was associated with the lymph node metastasis or the invasion depth. The results of the bioinformatics analysis showed that the target genes of miR-106a-5p were enriched in the multiple signaling pathways associated with the cancer. Conclusion miR-106a-5p is a molecular marker of high expression in gastric cancer and a potential cancer gene associated with lymph node metastasis and invasion depth.
ObjectiveTo investigate the relationship between metastatic lymph node ratio (MLNR) and prognosis of patients after radical resection of distal gastric cancer.MethodsWe retrospectively analyzed the clinicopathological data of 408 patients undergoing radical resection of distal gastric cancer (D2 or D2+ lymph node dissection) in Department of Gastrointestinal Surgery in the Affiliated Hospital of Southwest Medical University, from January 2010 to January 2014. Then we explored the influence of MLNR on the prognosis after radical resection of distal gastric cancer.ResultsWithout distinguishing pTNM staging, the overall survival situation of patient with MLNR≥0.15 and patient with MLNR<0.15 was statistically significant (χ2=3.775, P=0.046); when patients with staging of pTNM Ⅰ, there was no statistically significant MLNR could be calculated; when patients with staging of pTNM Ⅱ, the overall survival situation of patient with MLNR≥0.14 and patient with MLNR<0.14 was statistically significant (χ2=3.110, P=0.029); when patients with staging of pTNM Ⅲ, the overall survival situation of patient with MLNR≥0.10 and patient with MLNR<0.10 was statistically significant (χ2=1.631, P=0.004). Multivariate analysis showed that depth of invasion (pT stage) and MLNR were independent prognostic factors for prognosis of patients after radical resection of distal gastric cancer (P<0.05).ConclusionMLNR is a good prognostic indicator for patients with distal gastric cancer after radical resection.
ObjectiveTo summarize the diagnosis and treatment of a primary gastric colon cancer, and to explore its safety and feasibility.MethodThe clinical data of a patient with gastric cancer and sigmoid colon cancer who admitted to The Affiliated Yantai Yuding Hospital of Qingdao University in October 2017 was analyzed.ResultsThe patient underwent laparoscopic radical gastrectomy plus π anastomosis and laparoscopic radical resection of colon cancer. The operation time was 330 min and the intraoperative blood loss was 120 mL. There were no complications such as stomach cramps and sputum after operation and he was successfully discharged on the 9th day after surgery. Postoperative pathological staging: gastric cancer (pT3N3M0, ⅢB) and sigmoid colon cancer (pT2N0M0, Ⅰ B).ConclusionsMultiple primary cancer of the simultaneous gastric colon should be diagnosed before operation. Laparoscopic minimally invasive treatment for gastric cancer with sigmoid colon cancer is safe and feasible, and can benefit patients.
