Objective To study the effect of interleukin-6,10 (IL-6,10), C-reactive protein (CRP), and fibrinogen (FIB) on inflammatory response of lower limbs deep vein thrombosis (DVT). Methods Thirty patients with acute lower limb DVT (DVT group) and 30 volunteers (normal control group) were included in this study, and then the concentrations of serum IL-6, IL-10, CRP, and FIB were detected. Results The concentrations of serum IL-6, IL-10, CRP, and FIB of patients in DVT group before treatment were higher than those in normal control group (Plt;0.001). Compared with before treatment, the concentrations of serum IL-6, CRP, and FIB of patients after treatment were lower in DVT group (Plt;0.001), however, the concentration of serum IL-10 was higher (Plt;0.001). There was no difference of the concentrations of serum FIB between DVT group after treatment and normal control group (Pgt;0.05), but the concentrations of serum IL-6, IL-10, and CRP of patients in DVT group after treatment were higher than those in normal control group (Plt;0.05). Conclusion Inflammatory factors may involve in DVT. Therein IL-6, CRP, and FIB play important roles in acute stage of DVT, and IL-10 may have an anti-inflammatory effect.
ObjectiveTo investigate the relation between histology type and prognosis of gastric cancer.MethodsThe clinical database of 311 patients who underwent surgical resection for gastric cancer in our hospital, between 2000 and 2004, was retrospectively reviewed and analyzed with SPSS 13.0. ResultsLymph node metastasis, tumor invasion depth, and Borrman type of gastric cancer were related with histology type （χ2 test, Plt;0.05）. KaplanMeier survival analysis was used to compare the survival rate and showed that there was a significant difference between highly/moderately differentiated cancers and the poorly differentiated (Plt;0.05), while there was no statistical difference between those patients with same invasion depth （Pgt;0.05）. ConclusionThe prognosis of gastric cancers with same invasion depth is same regardless of their histology types.
【Abstract】ObjectiveTo study the effect of down-regulation of E-cadherin on the invasion ability of tumor cells. MethodsHuman pancreatic carcinoma cell line JHP-1 was treated with E-cadherin antisense oligodeoxynucleotied (ASODN). The immunocytochemistry, Western blot were used to detect the expression and the contents of E-cadherin in the tumor cells, and the invasive ability of tumor cells were evaluated by invasive-MTT assay. Results Treated with E-cadherin ASODN, the expression of E-cadherin on JHP-1 cells were reduced, and the protein contents were decreased as well compared with control groups and ODN group. The invasive ability of JHP-1 cells to the basement membrane was increased (P＜0.001) compared with ODN group and control group. ConclusionE-cadherin was related to the invasive ability of tumor cells.
Objective To investigate the risk factors for insulin resistance (IR) after selective operation in the department of general surgery. Methods Two hundred and sixty-three patients including 122 males and 141 females after selective operation between March 2009 and October 2009 in The First Affiliated Hospital of Xi’an Jiaotong University were studied. Sex, age, histories of smoking and drinking, hypertensive disease, history of operation, height, weight, waist circumference, anesthesia method, operation duration, operation method, and volumes of transfusion and liquid injection during operation were recorded. The fasting blood glucose (BG) and fasting plasma insulin (INS) were tested for selectively operative patients on day 1 before and after surgery. Insulin resistance index (HOMA-IR) and the index of insulin secretion (HOMA-β) were calculated with homeostasis model assessment (HOMA). Logarithms of HOMA-IR (lnHOMA-IR) was taken because that HOMA-IR was not normal distribution. Results The levels of fasting BG, fasting plasma INS, and lnHOMA-IR on day 1 after operation were higher than those on day 1 before operation (Plt;0.001). IR was correlated with patients’ sex (P=0.002), the history of smoking (P=0.033), waist circumference (P=0.000), operation method (P=0.007), and the volume of liquid injection during operation (P=0.001). A significant elevation of the change of lnHOMA-IR level was found between abdominal and nonabdominal surgery (Plt;0.001). Conclusions IR occurs in selectively operative patients in the department of general surgery. It is helpful for depressing IR to control the intensity of surgery.
Objective To investigate the risk factors of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer and its influence on recent clinical outcome. Methods Retrospective case-control study was carried out. Clinical data of 135 patients underwent laparoscopic assisted radical gastrectomy for gastric cancer admitted to the Department of General Surgery in the First Affiliated Hospital of Xi’an Jiaotong University Medical College from June 2016 to June 2021 were collected. Postoperative hypoproteinemia was defined as serum albumin <30 g/Lon postoperative day 1. Observation indications: ① the incidence of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer; ② analysis of risk factors for postoperative hypoproteinemia; ③ influence of postoperative hypoproteinemia on recent clinical outcome. Results ① Among 135 patients, 56 patients developed hypoproteinemia after operation (hypoproteinemia group) with an incidence of 41.5%, 79 patients without hypoproteinemia (non- hypoproteinemia group). ② Univariate analysis of risk factors for postoperative hypoproteinemia showed that age, preoperative albumin level, preoperative plasma volume, preoperative leukocyte, preoperative hemoglobin level, maximum tumor diameter, net intake on operative day and operative time were related to the occurrence of postoperative hypoproteinemia (P<0.05). The results of multivariate analysis showed that: age ≥65 years [OR=6.320, 95%CI (2.340, 17.068), P＜0.001], preoperative albumin level <35 g/L [OR=5.951, 95%CI (1.815, 19.507), P=0.003], operative time ≥5 h [OR=3.171, 95%CI (1.164, 8.640), P=0.024], and net intake on operative day ≥3 000 mL [OR=5.153, 95%CI (1.616, 16.432), P=0.006] were risk factors for postoperative hypoproteinemia. ③ Within 30 days after operation, the incidence of non surgery related complications in the hypoproteinemia group and the non-hypoproteinemia group were 30.4% (17/56) and 13.9% (11/79), respectively, and the incidence of surgery related complications were 10.7% (6/56) and 1.3% (1/79), respectively, with statistically significant differences (P<0.05). Conclusions Age ≥65 years, preoperative albumin level <35 g/L, operative time ≥5 h and net intake on operative day ≥3 000 mL are risk factors for hypoproteinemia after laparoscopic assisted radical gastrectomy. For patients suffered from hypoproteinemia (albumin <30 g/L) after surgery, the incidences of both surgery-related complications and non-surgery-related complications increase.
