OBJECTIVE: To observe the correlation between serum level of TXB2, 6-Keto-PGF1alpha and liver metastasis. METHODS: The metastatic model was made by injection of W256 carcinosarcoma. Rats were randomly divided into two groups: rats with blood stasis group and control group. Rats in control group were given normal saline via abdominal cavity once a day. Rats in blood stasis group were injected adrenalin in the fourteenth day. Tumor size and liver metastasis were observed. Serum TXB2 and 6-Keto-PGF1alpha were tested by radioimmunoassay. RESULTS: Tumor size in rats with blood stasis was significantly smaller than that of the control group (P<0.01). Occurrence of liver metastasis in rats with blood stasis was significantly lower than that of the control group (P<0.01). The values of 6-Keto-PGF1alpha, TXB2, and TXB2/6-Keto-PGF1alpha were higher in the group with blood stasis. CONCLUSION: In the status of blood stasis, W256 carcinosarcoma grows slowly, and liver metastasis increases insignificantly, with the elevations of 6-Keto-PGF1alpha, TXB2 and TXB2/6-Keto-PGF1alpha.

Abstract: Objective To explore the relationship between body mass index (BMI), waist-hip ratio (WHR) and the risk of gout in Urumqi. Methods A total of 516 male patients with gout in a third-class hospital in Urumqi from 2015 to 2019 were randomly selected as the gout group and 516 male healthy subjects in the same hospital as the control group. The relevant blood biochemical indexes were examined and analyzed. Blood pressure, waist circumference and hip circumference were measured. Body mass index and waist-to-hip ratio were calculated. Logistic regression model was used to analyze the relationship between overweight / obesity, waist-to-hip ratio and the risk of gout. The test level is α = 0.05. Results Uric acid, glucose, urea nitrogen, creatinine, triglyceride, low-density lipoprotein, systolic blood pressure, weight and waist circumference in gout group were higher than those in control group, and the differences were statistically significant (P<0.05); There were no significant differences in age, height and diastolic blood pressure between the two groups (P<0.05). There was a positive correlation between BMI and WHR and the occurrence of gout (r=0.272, 0.345, P<0.05). There were significant differences in BMI, WHR and waist circumference between the gout group and the control group(χ2= 55.338, 54.928, 54.153, P<0.05). After adjusting for age, aerobic exercise and other confounding factors, the results of multi-factor unconditional Logistic regression analysis showed that the odds ratio (OR) of gout in patients with BMI of 24.00-27.99 kg/m2 and ≥28.00 kg/m2 was 2.005 (1.337-3.006) and 2.677 (1.668-4.296) times higher than that of patients with normal BMI, respectively. The OR value of gout in patients with WHR≥0.90 was 1.668 times higher than that in patients with normal WHR, and the difference was statistically significant. The results of subgroup analysis according to age are generally similar. Conclusions The BMI and WHR of man with gout in Urumqi are higher than those of normal people, and BMI, waist circumference and WHR are all associated with the incidence of gout. The risk of gout increases with the increase of BMI and WHR.
