[Relationship of glucose metabolic rate and plasma levels of adiponectin and leptin in patients with metabolic syndrome].

OBJECTIVE: To investigate the relationship of glucose metabolic rate (GMR) and plasma levels of adiponectin and leptin in patients with metabolic syndrome (MS). METHODS: A total of 30 MS subjects aged 36-60 years old were selected as MS group. And 20 normal adults were selected as control group. The GMR was evaluated by the technique of hyperinsulinemic euglycemia clamp. The plasma concentrations of adiponectin and leptin were detected by enzyme-linked immunosorbent assay (ELISA). Blood pressure, waist circumference (WC), body weight and body height were measured. RESULTS: (1) During the steady state (last 30 min), the GMR was significantly lower in MS group than that in control Group [(4.13 ± 1.34) mg×kg(-1)×min(-1) vs (8.33 ± 1.59) mg·kg(-1)×min(-1), P < 0.01]. (2) The plasma level of adiponectin was significantly lower in MS group than that in control group [(5.15 ± 2.54) µg/ml vs (10.28 ± 5.50) µg/ml, P < 0.01]. The plasma level of leptin were significantly higher in MS group than that in control group [(189.37 ± 90.48) ng/ml vs (126.55 ± 72.70) ng/ml, P < 0.01]. (3) In MS group, glucose metabolic rate was associated with WC, BMI, TG, HDL-C FINS, leptin, and adiponectin, (all P < 0.05). CONCLUSION: The technique of hyperinsulinemic euglycemic clamp shows that the BMR of MS patients significantly decreases. It may be associated with their lowered plasma levels of adiponectin and leptin.

[Cross-sectional study of current situation of glycemic control with type 1 diabetes in Guangdong Province].

OBJECTIVE: To investigate the glycemic control and the related factors of type 1 diabetic patients in Guangdong Province. METHODS: Medical records and blood samples of type 1 diabetic patients were collected in 89 tertiary and secondary hospitals from all of the 21 cities in Guangdong Province. The clinical data were analyzed to explore the correlates of glycemic control. HbA1c levels, measured in Guangdong Diabetes Center, were used to assess glycemic control. RESULTS: 851 patients were enrolled from August 6, 2010 to May 25, 2011. There were 408 males and 443 females. The median (interquartile range) age was 29.6 years (20.3 - 41.3 years). The onset age of diabetes was 25.3 years (15.7 - 35.5 years). The disease duration was 3.3 years (1.0 - 7.3 years). The BMI was 19.9 kg/m(2) (17.9 - 21.8 kg/m(2)). HbA1c levels were 8.6% (6.9% - 11.0%) and only 234 (27.50%) patients reached the age-specific target levels. Correlates with poorer glycemic control were 13 - 19 years old (vs 7 - 12 and ≥ 20 years old), lower household income, not on dietary intervention, never accepting diabetic education and shorter diabetic duration. CONCLUSION: The majority of Guangdong type 1 diabetic patients did not achieve target values for glycemic control, indicating an urgent need for comprehensive management to improve glycemic control.

Treatment of middle/late stage primary hepatic carcinoma by Chinese medicine comprehensive therapy: A prospective randomized controlled study.

OBJECTIVE: To observe the efficacy of Chinese medicine comprehensive therapeutic project in treating the middle/late stage primary hepatic carcinoma (PHC). METHODS: With prospective randomized controlled design, 97 patients with PHC were assigned to the test group (49 cases) treated with Chinese medicine comprehensive therapy using Oleum fructus bruceas intervention combining oral intake of Ganji Decoction and external application of Ailitong, and the control group (48 cases) treated with chemotherapeutic agents combining iodized oil chemo-embolization and analgesics. The immediate and long-term efficacy, adverse reaction, pain-relieving initial time (PRIT) and pain-relieving sustained time (PRST) of the treatment, as well as the change in relieving patients' quality of life (QOL) were observed. RESULTS: The difference between the two groups in illness control rate was statistically insignificant (P>0.05), but the adverse reaction occurrence rate in the test group was lesser than that in the control group (P<0.05). PRIT was insignificantly different in the two groups (P>0.05), but the PRST was significantly superior in the test group than that in the control group (10.37+/-2.18 h vs 7.78+/-1.95 h, P<0.01). After treatment, the increased Karnofsky scores in the test group indicated that the patients' somatic activity, symptoms and QOL were improved significantly, which were significantly superior to those in the control group (P<0.05). The survival rate in the two groups was similar at the 3rd month after treatment, but the test group did show superiority in terms of half- and 1-year survival rate (65.9% vs 42.5% and 38.6% vs 18.1%, respectively, P<0.05). The median survival time in the test group was 8.9 months and that in the control group was 5.3 months. CONCLUSION: Chinese medicine comprehensive therapy is an effective treatment for the middle/late stage patients of PHC, and it could extend the PRST, improve the patients' QOL and long-term survival with less adverse reaction.

[Clinical observation on effect of Yiqi Yangyin Huoxue Tongfu principle in treating diabetes mellitus type 2 of secondary failure to sulfonylurea agents].

OBJECTIVE: To observe the effect of Yiqi Yangyin Huoxue Tongfu (YYHT) principle in treating diabetes mellitus type 2 of secondary failure to sulfonylurea agents. METHODS: Forty patients were randomly divided into two groups, based on the unchanged previous treatment of sulfonylurea agents, Chinese decoction prescribed according to YYHT principle was given to the treated group and rosiglitazone was given to the control group. Changes of insulin sensitivity (SI), insulin response to glucose (IRG), insulin sensitive index (ISI), tumor necrosis factor-alpha (TNF-alpha), endothelin-1 (ET-1), 6-keto-prostaglandin F1alpha(6-keto-PGF1alpha) and thromboxane B2 (TXB2) were observed. RESULTS: The total effective rate in the treated group was 71.4%, that on improving peripheral insulin resistance was 76.2%, the two parameters were similar to those in the control group. In the treated group, SI, ISI were significantly improved, and TNF-alpha, ET-1 and TXB2 significantly lowered, but no change of IRR was found. CONCLUSION: Application of YYHT principle in treating patients with diabetes mellitus type 2 of secondary failure to sulfonylurea agents could alleviate the peripheral resistance to insulin, inhibit TNF-alpha, and protect the vascular endothelial cells.
