CONCLUSION: The separation effect of peaks in fingerprints is better and the characteristic is also obvious.The RSD values of precision and reproducibility are less than 5%.This method can be used for the quality control of Salvia miltiorrhizae Bge.

Objective To investigate the feasibility and complications of the transcranial approach for resection of tumors that involve the anterior skull base, orbit and paranasal sinuses. Methods Nine cases of tumors involving the anterior skull base, orbit and paranasal sinuses, which were resected by transcranial approach alone in our hospital from July 2000 to April 2001, were retrospectively analyzed. All patients had the lesion of the anterior skull base and orbit, and 5 cases had additional paranasal sinuses involvement. Results The tumors in all patients were removed completely. Complications occurred in three cases, including one case of cerebrospinal fluid leaking and two cases of blepharoptosis. One died of tumor recurrence one year after operation. Eight were tumor-free survival during the follow-up period of 20～29 months. Conclusion The transcranial approach can completely remove the tumors widely invading the anterior skull base, orbit and paranasal sinuses. Separation of the periosteum of the orbital roof can cause blepharoptosis, which leads to failure of cosmetics. Extending approach must be avoided if it is possible. The reconstruction of the skull base with pedicle pericranial flap may be the key factor to reduce complications.

Objectives To investigate the T cell subsets changes in hemorrhagic fever with renal syndrome (HFRS) patients. Methods 22 HFRS patients who were diagnosed in Qin Huang Dao Third Hospital from April 2005 to July 2005 were enrolled in this study and divided into two groups according to clinical manifestations. T cell subsets of the 22 patients were monitored at week 1, 4 and 12. Another 56 subjects were enrolled as healthy controls. Results B cell count was normal during the 12 weeks in all the subjects. NK cell decreased significantly at week 1, and recovered at week 4 rapidly. CD4+ T cell count was normal throughout the course of the disease, but the percentage of memory phenotypy increased at week 1and4, reaching(64.1±17.5)% and (59.9±10.1)%, but recovered at week 12. CD4+CD28+T cells were normal throughout the entire study. CD8+ T cell count increased dramatically at week 1 and 4, but finally recovered at week 12. The count of CD8+ CD28-T cells increased significantly at week 1 in low-grade goup, but in median-grade group, this increase lagged to week 4 and was not as significant as in low-grade group. The percentage of CD38+ or HLA-DR+ subsets of CD8+ T cell increased at week 1, 4. Conclusion The results confirmed the relationship between HFRS progression and cellular immunity. It revealed that, at the early stage of HFRS, rapid and effective cytotoxicity T lymphocyte response my contribute to clear Hantavirus away and improve HFRS symptom.
