[Incidence and risk factors of metabolic syndrome in rural community population on islands in Zhejiang province].

Objective: To estimate the incidence of metabolic syndrome and explore possible risk factors for metabolic syndrome in adults of rural communities in Yuhuan county, Zhejiang province, China. Methods: During June-December, 2018, a follow-up survey was conducted in participants without metabolic syndrome at baseline survey in 2012 to obtain the information collected in questionnaire survey, anthropometric data and laboratory data. The incidence of metabolic syndrome in the participants was estimated, and Logistic regression model was used to explore the risk factors, adjusted risk ratio (aRR) and 95%CI. Results: Among 3 162 participants, 522 new metabolic syndrome cases were identified. The 6-year cumulative incidence rate of metabolic syndrome was 16.5%, and the cumulative incidence rate was higher in women (20.6%) than that in men (12.3%, P<0.001). Those incidence rates were higher in those in jobless, smoking or drinking groups. Being women (aRR=1.96, 95%CI: 1.50-2.58) and family history of hypertension (aRR=1.31, 95%CI: 1.04-1.63) were independent risk factors for metabolic syndrome. Conclusion: The follow up indicated that the incidence of metabolic syndrome was relatively high in rural adults on islands in Zhejiang, and women or those with family history of hypertension were more likely to have metabolic syndrome.

[Differential population screening and efficacy analysis of (125)I implantation after radiofrequency ablation of primary liver cancer].

Objective: To investigate the clinical efficacy radiofrequency ablation (RFA) combined with (125)I radioactive seed implantation in treatment of hepatocellular carcinoma HCC with the tumor diameter 3-5 cm. Methods: One hundred patients with HCC diagnosed clinically or pathologically with Barcelona staging of B or C in Lishui Central Hospital from February 2012 to September 2017 were retrospectively analyzed. Of the included 100 cases, 89 were males and 11 were females with the mean age of 18-80 (57±11) years old.According to the treatment modality, the subjects were divided into control group (RFA, n=67) and combined group (RFA+(125)I, n=33). Patients in control group were only received RFA and cases in combined group received RFA plus sequenced with (125)I implantation therapy. The prognosis of progression free survival (PFS) and overall survival (OS) between the two groups were compared through the Kaplan-Meier curve and Log-rank test. Results: The median follow-up time period was 6-55 months in the last follow-up time point of Dec 30, 2017. The median PFS were 4-55 (23.0±4.7) and 1-53 (12.0±1.6) months for combined and control groups respectively with significant statistical difference (P=0.015). The median OS were 6-55 (42.0±7.9) and 2-55 (38.0±2.8) months for combined and control groups with the trend of improvement in combined group, but without statistical difference (P=0.444). Subgroup analysis further indicated that the PFS was significant improved in patients with residual tumor lesions who received the combined treatment (PFS: 18 vs 9 months, P=0.025). However, there was no statistical difference for PFS between the control and combined treatment groups for cases without residual tumor lesions after RAF treatment(P=0.685). Conclusions: PFS was obviously increased in HCC patients(tumor diameter 3-5 cm) who received(125)I implantation after radiofrequency ablation, especially for cases with residual tumor lesions.

[Efficacy analysis of radiofrequency ablation combined with 125I seed for multiple nodular hepatocellular carcinoma].

OBJECTIVE: To investigate the clinical efficacy of radiofrequency ablation(RFA)combined with (125)I seed in patients with multiple nodular hepatocellular carcinoma(HCC). METHODS: The clinical data of 47 patients with multiple nodular HCC confirmed clinically or pathologically in the Fifth Affiliated Hospital of Wenzhou Medical University between January 2009 and September 2014 were retrospectively analyzed. All patients were divided into two groups depending on treatment: RFA group(n=29); RFA combined with (125)I seed group(n=18). Survival time was estimated with the Kaplan-Meier analysis. The survival curve was compared by Log-rank test. RESULTS: The clinical data and tumor situation of patients between two groups did not show significant differences. The follow-up time ranged from 2 to 55 months. At the end of the study, the median progression-free survival of two groups were 18 months and 11 months, and the differences were statistically significant(P=0.036). The overall survival rates in RFA combined with (125)I seed group at 1, 2, and 3 years (94.4%, 78.0%, 66.8%, respectively) were higher than those in RFA group (88.5%, 68.6%, 57.1%, respectively). However, the differences between the two groups were not statistically significant(P=0.554). CONCLUSIONS: For multiple nodular HCC, RFA combined with (125)I seed can prolong progression-free survival, have an advantage in local control rate, and is better than single RFA at short-term curative effect.However, its long-term outcomes should be further explored by a large-sample, multi-center and randomized trial.

Comparative study of several microinvasive treatments for large hepatocellular carcinoma.

OBJECTIVE: To study the prognosis of large hepatocellular carcinoma after interventional radiology and to compare the efficacy of different microinvasive treatments. PATIENTS AND METHODS: The clinical data of 46 large hepatocellular carcinoma patients confirmed by clinical treatment or pathological examination were retrospectively analyzed. Patients were divided into two groups (TACE+RFA n=23 cases, and Combination group n=23 cases), according to the treatments method. two groups were followed up for 5-48 months. Survival was estimated using the Kaplan-Meier method and the survival curve was compared by log-rank test. RESULTS: Median follow-up time was 33 months in both groups. The median survival time in Combination group (n=41 months) was significantly longer than TACE+RFA group (n=33 months) (p = 0.052). Median progress-free survival (PFS) is 10 months in Combination group and 8 months in TACE+RFA group. The difference was statistically significant (p = 0.023). The tumor inhibition rate was 82.6% and 52.2%, respectively and the difference was statistically significant (p = 0.028). The overall survival rate at l, 2 and 3 years was 100%, 95.7% and 55.8% respectively in Combination group was higher than TACE+RFA group at 91.3%, 55.8% and 38.3% respectively. The difference was not statistically significant. CONCLUSIONS: For large hepatocellular carcinoma, combined method was superior to TACE+RFA and comprehensive treatment can improve the local-control rate.
