ABSTRACT
A male patient, with diagnose of Madelung disease, was admitted in September 2009. He has been a heavy drinker for decades before onset of the disease. This patient was characterized by the large amount of symmetrical deposits of adipose tissue in the subcutaneous layer around neck, and without obesity on other sites. The excessive adipose tissue was surgically removed by three steps. Appearance almost returned to normal. No recurrence happened after 8 years of follow-up.
ABSTRACT
Objective@#To analyze the clinicopathological features of type 2 diabetes mellitus complicated with colorectal cancer (DCRC).@*Methods@#A case-control study was conducted. Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ2 test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment.@*Results@#Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5±1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m2 vs. (23.2±0.4) kg/m2, t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1±0.2) mmol/L vs. (1.5±0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti- thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×1012/L vs. (4.5±0.1)×1012L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD-1 and PD-L1 positive cells between two groups (all P>0.05).@*Conclusions@#The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.
ABSTRACT
Objective To investigate the effect of early enteral nutrition(EN) support after gastreetomy and evaluate its feasibility. Methods Early enteral feeding was used in 129 eases with gastreetomy in 20 hours after operation. Result One hundred and twenty-nine eases accepted early enteral nutrition support, 5 ea-ses appeared diarrhea. After adjusting the infusion speed and the temperature of nutrient fluid, symptoms of 4 eases vanished, 1 ease could not complete the early enteral feeding plan. Conclusions The early nutri-tion after gastreetomy is safe, reliable, simple and economical. The early nutrition can improve the nutrition state of postoperative patient effectively.
ABSTRACT
@#Objective To investigate the protective effect of the combination of glutamine (Gln) and ar-ginine (Arg) on intestinal barrier function in rats receiving fluorouracil (5-FU) chemotherapy.Methods Totally 40 male SD rats receiving 5-FU chemotherapy were equally randomized into four groups:enteral nutrition group,Gln group (enteral nutrition+Gln),Arg group (enteral nutrition+Arg),and Arg+Gln group (enteral nutri-tion+Arg+Gln).Observe the changes post chemotherapy such as the changes of body weight and urine lactulose/mannitol ratio before and after chemotherapy were recorded.On the 8 th post-therapy day,the blood endotoxin level in portal vein was measured,and lymph nodes and blood in portal vein were taken for bacterial culture;colon and jejunum specimens were also taken to measure the height of jejunum villus and the thickness of colon and jejunum.Results Body weights of Gln group,Arg group,and Arg+Gln group significantly increased after chemotherapy (P<0.05).The change of body weight was significantly lower in Arg+Gln group than in Gln group (P=0.002),while no such difference was found when compared with that in Arg group (P>0.05).Lactulose/manni-tol ratio in each group significantly increased after chemotherapy (P<0.05),and the change of lactulose/mannitol ratio was significantly higher in the enteral nutrition group than those in other groups (P=0.000);however,no such difference was found among other groups (P>0.05).The blood endotoxin level in portal vein was signifi-cantly higher in enteral nutrition group than in other groups (P=0.000);the endotoxin level was significantly lower in Gln group than in Arg group (P=O.035) and Arg+Gln group (P=0.000);however,no such differ-ence was found between Arg group and Arg+Gln group (P=0.109).The height of jejunum villus and the thick-ness of jejunum were significantly lower in enteral nutrition group than those in the other groups (P=O.000);the thickness of colon was significantly lower in enteral nutrition group than those in Arg group and Arg+Gln group (P=0.000);however,no such difference was found when compared with Gln group (P=0.058).The thickness of colon (P=0.040) and jejunum (P=0.010) was significantly higher in Gln group than that in Arg group;but there was no significant difference in term of the height of jejunum villus (P=0.286).Compared with Arg+Gln group,the thickness of jejunum in Gln group was significantly higher,but there was no significant difference in terms of the height of jejunum villus (P=0.286) or the thickness of jejunum (P=0.190).The thickness of co-lon was significantly lower in Arg group than in Arg+Gln group (P=0.010),while no such significant difference was found in terms of the height of jejunum villus (P=0.803) or the thickness of colon (P=0.059) when com-pared with Arg+Gln group.The bacterial culture results were not significantly different among all groups.Conclu-sions The combination of Arg and Gln has protective effects on intestinal barrier in rats receiving 5-FU chemother-apy.The protective effect of Gln is superior to that of Arg.No synergistic effect exists between Arg and Gln.
ABSTRACT
Objective To investigate and assess the effects of nutrison on rat gut barrier after 5-FU chemo-therapy. Methods Thirty male Sprague-Dawley rats were randomly assigned to three groups: EN group: nutrison intestinal nutrition; STD group: nutrison intestinal nutrition + chemotherapy; CHOW group: chow+ chemotherapy. The changies such as weight, lactulose / mannitol of urine samples before and after chem-otherapy were observed. At the 8th day, colon as well as jejunum tissue were also sampled for pathological examination to measure the height of jejunum villi, the thickness of colon and jejunum. Results Compared to EN group, the body weight the height of jejunum mucosa and the thickness of colon / jejunum loss of STD group was significantly decreased, as well as the L/M inceased. The data showed that CHOW group was bet-ter than EN group. Conclusions Intraperitoneal injection of 5-FU increased the intestinal permeability of rats and damaged the function of intestinal barrier. The intestinal mucosal protection effect of nutrison EN in post-chemotherapy rats was weaker than the effect of a free-eating group.
