ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of L-carnitine treatment on serum levels of brain natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) and cardiac function in children with heart dysfunction and severe hand-foot-mouth disease (HFMD).</p><p><b>METHODS</b>A total of 120 children with severe HFMD were enrolled and randomly and equally divided into routine treatment group and L-carnitine treatment group. Thirty healthy children served as the control group. HFMD patients were given anti-fever and antiviral treatment as the basic treatment, while the patients in the L-carnitine treatment group were given L-carnitine as an adjuvant treatment to the basic treatment. Treatment outcomes were observed in the two groups. For all the subjects, serum levels of BNP and NT-proBNP and cardiac function parameters including left ventricular ejection fraction (LVEF), fractional shortening (FS), and cardiac index (CI) were measured at different time points before and after treatment.</p><p><b>RESULTS</b>Before treatment, HFMD patients had significantly higher serum levels of BNP and NT-proBNP and heart rate but significantly lower LVEF, FS, and CI compared with the control group (P<0.05). After treatment, the L-carnitine treatment group had a significantly higher response rate than the routine treatment group (P<0.05). After 3 days of treatment, the serum levels of BNP and NT-proBNP, LVEF, FS, and CI were significantly reduced in the L-carnitine group (P<0.05); the L-carnitine group had significantly lower serum levels of BNP and NT-proBNP, LVEF, FS, and CI than the routine treatment group (P<0.05); there were no significant differences in the serum levels of BNP and NT-proBNP, LVEF, FS, or CI between the L-carnitine treatment and control groups (P>0.05). After 5 days of treatment, there were no significant differences in the serum levels of BNP and NT-proBNP, LVEF, FS, or CI between the L-carnitine treatment and routine treatment groups (P>0.05). Heart rate recovery was significantly slower in the routine treatment group than in the L-carnitine treatment group (P<0.05).</p><p><b>CONCLUSIONS</b>As an adjuvant therapy for severe HFMD, L-carnitine treatment has satisfactory short-term efficacy in reducing the serum levels of BNP and NT-proBNP and improving cardiac function, thus improving clinical outcomes.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of transarterial chemoembolization (TACE) using mixed emboli for hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>188 patients with HCC were divided into two groups according to the treatment modality: 103 patients in group A treated by routine iodine embolus agent; 85 patients in group B by mixed iodine embolus agent (ultra-liquified iodinized oil + gelatin sponge + chemotherapeutic agents). The pattern of the arrested iodine deposition in the tumor, response, resectability during follow-up, pathological changes, survival and complications in the two groups were analyzed and compared.</p><p><b>RESULTS</b>The pattern of full-and-dense iodine deposition in the tumor and the response rate (CR + PR) were 59.2% and 32.0% in group A, 89.4% and 56.5% in group B. Surgical resection after TACE was possible in 5.8% (6/103) of group A versus 15.3% (13/85) of group B. Complete tumor necrosis was observed in 1.0% and 4.7% in groups A and B, respectively. 1-, 2- and 3-year actual survival rates were 57.7%, 42.8% and 8.4% in group A, and 79.8%, 55.3%, 38.5% in group B. The difference in results between the two groups was statistically significant, however, the incidence of complication in the two groups was similar.</p><p><b>CONCLUSION</b>Transarterial chemoembolization with mixed iodine emboli is more effective than with the routine iodine emboli in the treatment of bulky or nodular hepatocellular carcinoma rich in blood supply. Mixed iodine emboli is tolerable without increase in severe complications.</p>
