The antifungal antibiotic produced by Streptomyces luteogriseus H-103 was purified by means of macroporous adsorbent resin, and the crystal of the antibiotic with high purity was got. In this paper, the methods of purification by adsorbing of microporous adsorbent resin and detection by reversed high performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) were established. The result appeared that resin X-5 is the best adsorbent, the eluant is 50% ethanol. The antibiotic was successfully separated on Agilent~(TM)20RBA?310SB C_(18 )column (150mm?4.6mm i.d,5?m) , using a mixture of acetonitrile (A)-H_(2)O (B) as a mobile phase under gradient elution at a flow of 0.8mL/min at 30℃.0~4.0 min, V(A)∶V(B)=20∶80, 4.0~9.5min, V(A)∶V(B)=45∶55, then V(A)∶V(B)=80∶20. The drift tube temperature and the air carrier gas flow rate of the ELSD were set at 115℃ and 2.3L/min.

Objective To observe the clinical efficacy of acupoint sticking with Chan Wu gel in managing cancer pain.Method A hundred patients were randomized into a treatment group of 50 cases and a control group of 50 cases. The treatment group was intervened by thethree-step analgesic ladder plus acupoint sticking with Chan Wu gel; the control group was by the three-step analgesic ladder alone. The decrease of the pain degree, action and lasting time of analgesia, and adverse reactions in the two groups were observed.Result The treatment group was superior to the control group in comparing the release of pain, action and lasting time of analgesia; the occurrence rate of adverse reactions in the treatment group was obviously lower than that in the control group(P<0.05).Conclusion The conventional three-step analgesic ladder plus acupoint sticking with Chan Wu gel is effective in mitigating cancer pain, and it can reduce the dose of the three-step analgesics and the adverse reactions.

Objective To observe and analyze the CT and MR imaging of the structures in the region of the jugular foramen (JF) on the base of thin-slice anatomic study. Methods Having been scanned by multislice CT and 1.5T MR scanner, two formalin-preserved adult cadavers were dissected into 1.0 mm thickness contiguous sections in transverse plane. Twenty cases without skull base and nasopharyngeal history received routine and post-contrast CT examinations with spiral and HQ mode. Twenty healthy volunteers received MR scanning, including SE T 1WI, FSE T 2WI, and 3D RF-FAST (3D Radio-Frequency Fourier Acquired Steady-State) sequences. Results JF region was divided into three levels, which included inner aperture, the jugular cavity, and the outer aperture. At the entrance of JF, there were glossopharyngeal canal and vagal canal, which wrapped the Ⅸ nerve and Ⅹ and Ⅺ nerves, respectively. CT images could display these canals in 20 cases (100%). Furthermore, the Ⅸ, Ⅹ, and Ⅺ nerves could be identified on different MR sequences. 17 cases (85%) were displayed on 3D RF-FAST, 14 cases (70%) on SE T 1WI, and 10 cases (50%) on FSE T 2WI, respectively. From the anterior to the posterior compartment within the JF cavity, the structures ranged as follows: the Ⅸ nerve, the inferior petrosal sinus, the Ⅹ and Ⅺ nerves, and the jugular bulb. These neuro-vessel structures could not be distinguished on CT, SE T 1WI, and FSE T 2WI images, except for 3D RF-FAST (16 cases, 80%). The outer aperture of JF was adjacent to the hypoglossal canal. The shape of JF outer aperture could be evaluated on CT images. On the oblique plane, which was parallel to the hypoglossal canal, the posterior cranial nerves could be detected to enter/exit the skull through the JF and hypoglossal canal separately. Conclusion The complement of CT and MR imaging would be helpful to distinguish the structures in the region of JF.
