Sixty SD rats of either sex, weighing 150-280g , were divided into control ( C ), vitamin E(Vit E)and SOD groups. An anesthetized open-chest preparation with LCA occlusion was perfromed for 5min, and followed by 60 min reperfusion . ECG , arterial pressure (AP), left ventricular pressure ( LVP ) , dP/dt and epicardial map-ping

OBJECTIVE: To isolate and identify the secondary metabolites of Cordyceps cardinalis for providing reference for the further exploration of the active substance of C. cardinalis and the natural product library of Cordyceps. METHODS: The compounds from C. cardinalis fermentation broth were isolated by silica gel column chromatography, C18 reverse phase silica gel chromatography, Sephadex LH-20 gel column chromatography, TLC and so on. The structures of isolated compound were identified by 1H-NMR, 13C-NMR and MS spectra. RESULTS: Six compounds were isolated from the ethyl acetate extract of C. cardinalis fermentation broth as 5-methyl-1, 3-benzenediol (compound 1), 4-hydroxy-17R-methylincisterol (compound 2), 5α, 8 α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol (compound 3),3β,5α,6β-trihydroxy-(22E,24R)-ergosta-7,22-dien (compound 4), uridine (compound 5), oosporein (compound 6). CONCLUSIONS: Six compounds are isolated from C. cardinalis strain, among which compound 1 and compound 2 are isolated from the genus Cordyceps for the first time.

Objective To explore the accuracy of ultrasound in thyroid cancer screening and the reasonable operation of thyroid carcinoma. Methods Clinical data of 158 cases of thyroid carcinoma in recent three years were analyzed ret-rospectively in Yidu Central Hospital. Results The accuracy of ultrasound examination for thyroid carcinoma was more than 90%,even 98.3% combined with ultrasound contrast. Individual surgical approaches were used in this group. Half gland and isthmic portion and majority opposite side excision plus central lymph node dissection had been performed in 131 cases of patients with thyroid microcarcinoma,and lymph node metastasis rate was 19.8%(26/131). Conclusion Ultrasound and ultrasound contrast can significantly improve the detection rate of thyroid carcinoma and with high ac-curacy. It is also useful to make some judgments lymph node metastasis. Central lymph node dissection should be per-formed combining with gland excision in thyroid microcarcinoma.
