Objective To evaluate the current situation of randomized controlled trials/ clinical controlled trials (RCT/CCT) on chronic gastritis and whether it could offer reliable evidence for clinical practice in China. Method RCT/CCT on chronic gastritis from eight Chinese clinical journals were searched manually and assessed according to international standard. Results 823 issues containing 213 therapeutic articles were searched and 81 RCT/CCT were identified and assessed. Conclusions The quantity and quality of RCT/CCT on Chronic gastritis in China could not meet the need of clinical practice. RCT/CCT of western medical therapy are much better than those of traditional Chinese therapy and integrated traditional Chinese and western medical therapy ones.
Objective To observe the effects of peritoneal ventilation with pure oxygen in the rabbits with hypoxaemia and hypercapnia induced by mechanical controlled hypoventilation. Methods Sixteen rabbits were invasively ventilated after trachea incision. Hypoxaemia and hypercapnia were induced by hypoventilation which was implemented both by degrading ventilation parameters and respiratory depression induced by intravenous infusion of muscle relaxant. Then pure oxygen was insufflated into the peritoneal cavity and arterial blood gases were measured every 30 minutes for two hours. Results The PaO2 was ( 52. 50 ±3. 46) mmHg at baseline and increased to ( 76. 46 ±7. 79) mm Hg, ( 79. 62 ±9. 53) mm Hg,( 78. 54 ±7. 18) mmHg, and ( 81. 1 ±8. 3) mm Hg, respectively at 30, 60, 90, and 120 minutes after the peritoneal ventilation with pure oxgen( all P lt; 0. 05) . Meanwhile PaCO2 was ( 63. 84 ±9. 09) mm Hg at baseline and ( 59. 84 ±14. 22) mmHg, ( 59. 16 ±15. 5) mmHg, ( 60. 02 ±7. 07) mmHg, and ( 61. 38 ±6. 56) mm Hg, respectively at 30, 60, 90, and 120 minutes after the peritoneal ventilation with pure oxgen with no significant change( P gt;0. 05) . Conclusion Peritoneal ventilation can obviously improve hypoxaemia induced by mechanical controlled hypoventilation, whereas hypercapnia remains unchanged.
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.
Objective To explore the effects of heat-inactivated Lactobacillus gasseri TMC0356 on liver lipid metabolism in rats with metabolic syndrome (MS) and its possible mechanism. Methods Sixty male Sprague-Dawley rats were selected. Rats were randomly divided into 5 groups, including control group, MS model group and three TMC0356 test groups (low-, medium- and high-dose groups). The rats in each group were fed with different diets for 7 days, and the liver was dissected and removed after 15 weeks. The mRNA and protein expression levels of peroxisome hyperbioactive receptor-α (PPAR-α), sterol regulatory element binding protein-1c (REBP-1c), fatty acid synthase (FAS) and carnitine lipoacyltransferase-1 (CPT-1) genes in liver were detected. Results There was no significant difference in the mRNA expression of PPAR-α, SREBP-1c or CPT-1 among the five groups (P>0.05). The mRNA expression of FAS in low-dose TMC0356 test group was lower than that in MS model group (P=0.011), medium-dose TMC0356 test group (P=0.042) and high-dose TMC0356 test group (P=0.009). There was no significant difference in the expression of FAS mRNA between other groups (P>0.05). There was no significant difference in the protein expression of PPAR-α, SREBP-1c or FAS among the five groups (P>0.05). The protein expression of CPT-1 in low-dose TMC0356 test group was higher than that in control group (P=0.033) and high-dose TMC0356 test group (P=0.043). There was no significant difference in the protein expression of CPT-1 between the other groups (P>0.05). Conclusion Heat-inactivated Lactobacillus gasseri TMC0356 may improve the symptoms of metabolic disorder in rats by suppressing appetite, improving insulin resistance, and downregulating the expression of key fat metabolism genes such as FAS and SREBP-1c.
Motor function was investigated by constant perfusion manometry in the Roux limb of ten patients who had undergone total gastrectomy and Roux-en-Y anastomosis. Results showed that in the fasting state, the migrating motor complex (MMC) was comletely absent, retrograde in direction or bursts of nonphasic pressure activity. Reduced motor activity patterns occurred after the meal in some patients. Four patients failed to convert fasting state into the feeding state. Total gastrectomy with Roux-en-Y anastomoses provakes a relatively severe distubance in motor function, which could contribute to postoperative upper abdominal distress.
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 compare clinical outcome between single-incision laparoscopic subtotal gastrectomy (SILSG) versus laparoscopy-assisted subtotal gastrectomy (LASG) in treatment of benign gastric ulcer and duodenal ulcer. MethodsClinical data of 37 patients with benign gastric ulcer or duodenal ulcer who underwent laparoscopic subtotal gastrectomy between Jan. 2008 and Feb. 2015 at Shengjing Hospital of China Medical University was collected retrospectively. Among them, 15 patients underwent SILSG and 22 patients underwent LASG. Demographic, intraoperative, and postoperative data was analyzed and compared between the 2 groups. ResultsThe operative time of SILSG group was significantly longer than that of LASG group (P < 0.050). However, the postoperative hospital stay was significantly shorter (P < 0.050), and the total patient scar assesment scale (PSAS) score was significantly lower (P < 0.050) in the SILSG group than those of LASG group. There was no significant difference between the 2 groups with respect to other variables (P > 0.050), such as conversion rate, intraoperative blood loss, postoperative exhaust time, incidence of complication, and visual analog scale score of pain. All patients received postoperative follow up, and the period ranged from 6 months to 25 months, with a median of 11 months. During the follow up period, no one suffered from incision hernia and recurrence of ulcer. ConclusionCompared with LASG, SILSG is a technically feasible procedure with better cosmesis and equivalent curability.
ObjectiveTo investigate the diagnosis and treatment value of multi-disciplinary team (MDT) model in patient with gastric perforation combined with hyperthyroidism crisis.MethodWe summarized the experiences of MDT model in treating one case of gastric perforation with hyperthyroidism crisis in the Fuling Central Hospital of Chongqing City on February 2019.ResultsThis patient had a history of hyperthyroidism and didn’t receive systemic treatment, diagnosing as acute diffuse peritonitis and perforation of hollow organs. After MDT discussions and a series of treatments, including anti-infection, control of heart rate and hyperthyroidism, this patient underwent surgical treatment of gastric peptic ulcer perforation, during and after the surgery, this patient suffered from hyperthyroid crisis. The surgery was successful, with the operation time was about 110 min, and the blood loss was about 50 mL. There was no side injury occurred without blood transfusion, and the patient was cured and discharged on 20 days after operation. The patient was followed up for about 1 year, and the general condition and life returned to normal.ConclusionMDT discussion is a very helpful way in the treatment of gastric perforation combined with hyperthyroidism crisis and can give a better outcome.
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.
