Vanadium (V) is one of the trace elements It exists in many oxidation states which exhibit different biological activities. Our results in alloxan diabetic mice suggest that NaVO3 and VOSO4 can decrease blood glucose level. The hy-poglycemic effest of VOSO4 was found to be weaker than that of NaVO3, the toxicity ofVOSO4 is also lower. However VOSO4; showed no effect in normal mice. The mechanism of the hypoglycemic effect of VOSO4 appears to be similar to that of insulin.

Background Reliable intraocular pressure (IOP) measurement is essential in glaucomatous study.TonoLab is a newly designed tonometer for small animals,however,its repeatability and reproducibility remains unknown.Objective This study aimed to evaluate the repeatability and reproducibility of TonoLab rebound tonometer in DBA/2J mice.Methods Intraocular pressure was measured in both eyes of 63 DBA/2J mice aged 7 months under systemic anesthesia with TonoLab rebound tonometer.IOP of each eye was measured for 3 times by two observers independently and consecutively using TonoLab rebound tonometer,and the data were obtained in single blind method.Within standard deviation (Sw),interclass correlation coefficient (ICC),within coefficient of variation (CVw) and corresponding 95% confidence interval (CI) were calculated to evaluate the repeatability of measuring result from single observer,and Bland-Altman method was used to assess the agreement between two observers.The abnormal data which affected repeatability was analyzed.Results Among the 126 eyes,105 eyes showed the normal IOP with mean value (12.98 ± 1.05) mmHg from observer 1 and (12.41 ±0.92) mmHg from observer 2.Ocular hypertension was found in 21 eyes with mean value (27.76 ± 1.95) mmHg and (27.49 ± 1.28) mmHg for observer 1 and observer 2 respectively.Sw,ICC and CVw for observer 1/observer 2 were 1.34/1.11 mmHg,0.90/0.92,8.24%/7.42% in normal eyes and 2.21/1.49 mmHg,0.89/0.95,6.97%/4.82% in hypertensive eyes.The average bias between two measuring values from different observers was 0.60 mmHg in the normal eyes (95% CI:-5.20-6.30 mmHg) and 0.30 mmHg in the hypertensive eyes (95% CI:-7.30-7.80 mmHg).Conclusions TonoLab rebound tonometer can offer a good intraobserver repeatability in both normal and hypertensive eyes in mice,but the agreement between two observers is outside an acceptable level.So we consider IOP in mice obtained by TonoLab rebound tonometer is reliable and accurate from a single observer.

The therapeutic effect of a natural foodstuffs--Wei-Luo powder (WLP)composed of high protein, various essential amino acids, vitamins (B1, B2 and E), and trace elements (Fe, Zn, etc), on both monosodium glutamate (MSG) induced obese mice and alloxan diabetic mice were tested. After 16 days of feeding with WLP diet, the body weight and accumulation of fat in liver and adipose tissue (Lee index) in MSG mice were decreased significantly, WLP diet also caused significant reduction in carbohydrate tolerance of mice as compared with wheat diet. In addition, improvement of hyperglycemia and diabetic symptoms (polydipsia, polyuria and hyperphagia) in alloxan diabetic mice were observed. These results suggest that WLP diet may be beneficial for obesity and diabetic patients.

OBJECTIVE: To evaluate the treatment effect, quality of life and side-effect of transcatheter arterial chemoembolization (TACE) and traditional Chinese medicine (TCM) in treating metastatic liver cancer. METHODS: Thirty-nine cases of colon metastatic liver cancer were randomly divided into two groups. Both TACE and TCM were used in the treatment group, while only TACE was used in the control group. The drug used in TACE included floxuridine, pirarubicin, cisplatin, and the herbs for strengthening the spleen and regulating Qi were used in TCM. RESULTS: The response rate in the treatment group was 30% (45% including minor remission patients), and the median survival time was 18.6 months. While in the control group the response rate was 15.8% (36.8% including minor remission patients), and the median survival time was 14.3 months. The 1-, 2-, 3- year survival rates of treatment group and the control group were 70.2%, 40.3%, 13.0% and 68.7%, 29.5%, 10.3% respectively. There were fewer other organ metastases in the treatment group. The score from the EORTC quality of life questionnaire QLQ-C30 in treatment group was higher than that in the control group. CONCLUSION: Integration of TACE and TCM in treating colon metastatic liver cancer has better results.
