ObjectiveTo observe effect and safety of interstitial chemotherapy with 5-fluorouracil sustained release agent in radical operation of colorectal cancer. MethodsOne hundred and sixty patients with colorectal cancer from October 2011 to December 2013 were randomly divided into observation group and control group according to an incomplete random method, 78 cases of them were in the observation group and 82 cases of them were in the control group. All the patients were performed radical resection of colorectal cancer. The abdominal cavity and pelvic cavity were washed after surgery. 5-fluorouracil sustained release agent was implanted in the observation group patients for interstitial chemotherapy, the implant site was at the tumor resection area and the mesenteric artery. Routine chemotherapy was performed in these two groups after operation. The postoperative complications were observed. The postoperative local recurrence rate, liver metastasis rate, and 24-month survival rate were recorded. ResultsThe rates of abdominal complications and toxic effects had no significant differences between these two groups (P > 0.05). The rates of 12-month and 24-month local recurrence and the rate of liver metastasis in the observation group were significant lower than those in the control group[1.3% (1/78) versus 8.5% (7/82), x2=8.934, P=0.023; 5.2% (4/78) versus 23.2% (19/82), x2=14.834, P=0.004; 10.3% (8/78) versus 18.3% (15/82), x2=12.034, P=0.016]. The rate of 24-month survival in the observation group was significant higher than that in the control group[94.9% (74/78) versus 84.1% (69/82), x2=11.465, P=0.010]. ConclusionThe good safety of interstitial chemotherapy with 5-fluorouracil sustained release agent could effectively decrease local recurrence rate and liver metastasis rate of colorectal cancer after radical operation and improve survival time of patients.
Objective To summarize the treatment of pancreatic pseudo cyst in recent years. Methods Through the retrieval of relevant literatures, the progress in the treatment of pancreatic pseudo cyst in recent years were reviewed. Results Pancreatic pseudo cyst is a common complication of pancreatitis or pancreatic injury. Severe symptoms are often caused by large cysts or complications, and it can cause serious consequences. The main treatment methods are conservative treatment, percutaneous drainage, surgical treatment, endoscopic drainage technology, combined with traditional Chinese and Western medicine treatment, and each method has its own indications and advantages and disadvantages. Conclusion The treatment of pancreatic pseudo cyst is varied, and it should be individualized treatment according to different indications, different patients and the development stage of the disease.
ObjectiveTo systematically evaluation the efficacy and safety of laparoscopic cholecystectomy(LC) and open cholecystectomy(OC) for chronic atrophic cholecystitis. MethodsStandard electronic database such as PubMed, Web of science, Cochrane library, CNKI, VIP, CBM, and Wanfang database were searched to retrieve relevant randomized controlled trials(RCTs) that comparing LC with OC, which were analyzed systematically using RevMan5.2. ResultsSeven RCTs including 758 patients were brought into this Meta analysis. There were significant differences between two groups regarding operative time(MD=-27.70, 95% CI:-44.25--11.16, P=0.001), amount of blood loss during operation(MD=-113.25, 95% CI:-141.68--84.81, P < 0.000 01), the recovery time of gastrointestinal function(MD=-28.49, 95% CI:-29.80--27.18, P < 0.000 01), and length of hospital stay(MD=-3.83, 95% CI:-6.01--1.65, P=0.000 6), There were statistically significant difference in utilization rate of anodynes after operation(MD=0.12, 95% CI:0.06-0.23, P < 0.000 1) and terrible postoperative complications(MD=0.24, 95% CI:0.12-0.47, P < 0.000 01) between LC and OC. ConclusionsIn both efficacy and safety, LC for chronic atrophic cholecystitis are significantly superior than the traditional OC. But now the clinical randomized controlled trials about LC is less and the quality is poor, so that its long-term safety evaluation still needs large sample quality RCTs to be further verified.
ObjectiveTo investigate the distribution and content of endogenous salusin-βin septic rats. MethodsThirty-six SPF male SD rats were randomly divided into sham operation group (n=9) and septic model group (n=27).Only the cecum was turn in the sham operation group and the septic model was made by the cecal ligation and puncture (CLP) in the septic model group.The rats were sacrificed at 6 h, 12 h, and 24 h after modeling in the septic model group.The contents of salusin-βin the tissues of spleen, stomach, small intestine, hypothalamus, and serum specimens were detected by enzyme-linked immunosorbent assay. Results①The salusin-βendogenously generated in the rat tissues including the spleen, stomach, small intestine, hypothalamus, and serum.The content of salusin-βin the spleen tissue was higher than that in the other tissues (P < 0.05).②The contents of salusin-βin the spleen, stomach, small intestine tissues together with the serum increased significantly at 6 h after CLP as compared with the sham operation group (P < 0.05).The contents of salusin-βin the spleen tissue and serum were peaked at 12 h, in the small intestine tissue reached the summit at 24 h.While, the content of salusin-βhad no significant fluctuation in the stomach tissue.The content of salusin-βbegan to increase at 6 h in the hypothalamus tissue, and significantly increased at 12 h after CLP (P < 0.05). ConclusionThe time-dependent change of salusin-βin sepsis rats suggests that salusin-βmight be involved with the pathogenesis of sepsis.
ObjectiveTo investigate the mechanism of lignans-1inhibiting the proliferation of human gastric cancer cell line SGC-7901. MethodsThe morphological changes of the cells were observed by the inverted phase contrast microscope. The cell surviving ratio was determined by methylthiazoly tetrazolium (MTT) assay after lignans-1 added to the cells at different concentrations on human gastric cancer SGC-7901 cell line in vitro, and half maximal (50%) inhibitory concentration (IC50) values were calculated. The cell cycle phase distribution and apoptosis were measured by flow cytometry. The expressions of apoptosis associated proteins of Caspase3, Bcl-2 and Bax were determined by Western blot. ResultsMorphological examination showed that lignans-1 could destroy the SGC-7901 cells with the increasing concentration of lignans-1. The inhibitory effect of lignans-1 on SGC-7901 cell was associated with time-and dose-dependent manner at the different concentration (2.5-20 μg/mL), P < 0.05. The IC50 of lignans-1 on the SGC-7901 cells was 4.19 μg/mL. The rate of the apoptosis cells and G2/M phase cells raised significantly after 48 hours' treatment with lignans-1, as same as the expression of Caspase3 and Bax (P < 0.05). G0/G1 phase cells and Bcl-2 decreased significantly with the increasing concentration of lignans-1 (P < 0.05). ConclusionsThe lignans-1 could inhibit the proliferation of SGC-7901 cells and induce apoptosis by arresting cells at G2/M phase in vitro. The mechanism is associated with activation of Caspase3 and Bax and inhibition of Bcl-2.
