Objective:To establish two differential gene expression profiles of qi-deficiency and blood stasis syndrome before or after safflower injection treatment by using gene chip technology;compared and analyzed to ensure the effective genes that are responsible for the therapeutic effects of safflower injection against qi-deficiency and blood stasis syndrome in rats.Furthermore,speculated the effect mechanism of the therapeutic genes.Methods:Fifteen SD rats were randomly divided into 3 groups (n=5):control group,model group,and medication group.Qi-deficiency and blood stasis model was established by subjecting the rats to hunger and fatigue for two weeks.After a week of the modeling,safflower injection (100 mg/kg/d) was administered daily via the tail vein for 7 days in medication group,and the rats in model group were injected with saline of the same volume.Control group received normal feeding.At the end of the experiment,rats were killed and whole blood was collected to evaluate the blood stream change and extract mRNAs in blood samples.Qualified mRNAs were reverse transcribed into cDNA which was then used in gene chip hybridization.The genes regulated by safflower injection were determined by the fluorescence signal and the functional mechanisms of safflower injection were confirmed by further querying genealogy databases and reviewing literatures.Results:After two weeks of the modeling,the whole blood viscosity under various shear rates was significantly increased in the model rats which showed faint,blood stasis and weight loss,indicating that the model is made successfully.The increased whole blood viscosity and qi-deficiency and blood stasis syndrome were obviously reversed by safflower injection treatment.Compared with the control group,252 genes up-regulated while 54 genes down-regulated in model group;compared with the model group,196 genes up-regulated while 32 genes down-regulated.Among these,16 differentially expressed genes were involved in inflammation and immune response.Conclusions:Safflower injection was effective in treating qi deficiency and blood stasis syndrome,which was achieved by regulating inflammation related genes.

Objective To explore the efficacy of reserving thyroid cartilage combined with thyroid perichondrium flap to repair the defect of frontal-lateral window partial laryngectomy for T1b glottic cancinoma with anterior commissure involved.Methods From our hospital 22 cases diagnosed as T1b glottic cancer with anterior commissure invaded were treated with frontal-lateral window partial laryngectomy and were repaired by reserving thyroid cartilage combined with flap of thyroid perichondrium.All the patients were followed up for five years.The functions of respiratory and swallowing,voice rehabilitation,ratios of recurrence and survival were observed.Results All the patients succeeded in removing tracheal cannula.The decannulation rate was100％ and the aspiration rate was 0％.The voice functions in patients with postoperative classification (G) were higher than that of preoperative accounted for 86.4％ (19/22),and the same preoperative accounted for 13.6％ (3/22).There were 2 cases with tumor recurrence,one cases with recurrence in situ and one case with cervical lymph node metastasis.The recurrence rate was 9.1％ (2/22) and the 5 year survival rate was 95.5％ (21/22).Conclusion Frontal-lateral window partial laryngectomy reserving thyroid cartilage combined with thyroid perichondrium flap,is suitable for T1b glottic cancinoma invading anterior commissure.It can preserve the laryngeal framework and function relatively integrated with rare laryngeal stenosis and stabble repaired tissue.It also can effectively improve the sound quality and is worthy of clinical promotion.

OBJECTIVE To discuss the clinical features of primary lateral recess cysts of the sphenoid sinus,and to study the therapeutic effect of the endoscopic surgery.METHODS Nine patients with primary lateral recess cysts of the sphenoid sinus received endoscopic surgery from 2007 to 2015.Clinical data of the disease was analyzed retrospectively.Seven cases complained of cheek numbness as the chief complaint and 2 cases with progressive vision loss as the chief complaint.There were no obvious positive signs in head and facial regions.All cases were underwent marsupialization of the cysts via sphenoid sinus with nasal endoscope under general anesthesia.RESULTS All the cases had no intraoperative and postoperative complications,and the symptoms were disappeared after operation.No recurrence was found during follow-up of 6 to 24 months.The cavity of the cysts had permanent drainage to sphenoid sinus after operation in all the patients.CONCLUSION 1.Primary lateral recess cysts of the sphenoid sinus had unique symptoms and imaging characteristics.2.The marsupialization of the cysts via sphenoid sinus with nasal endoscope under general anesthesia was a safe,effective and minimally invasive method to management of the primary lateral recess cysts of the sphenoid sinus.
