Objective: To observe the effects of axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata on repairing defects after radical resection of scalp carcinoma in patients. Methods: From February 2006 to December 2015, twenty-one patients with scalp carcinoma were admitted to our hospital, and the carcinoma invaded external lamina or full-thickness of skull and dura mater. After perfect preoperative examination, carcinoma and scalp tissue in 3 to 5 cm from the edge of carcinoma, external lamina or full-thickness of skull and invaded dura mater were resected and sentinel lymph nodes around carcinoma were cleaned in 3 to 4 days after admission. The postoperative defects with size reached from 11 cm×8 cm to 22 cm×18 cm. The flap transplantation was performed at the same time when quick frozen pathological examination results of resected scalp carcinoma margin tissue, skull, dura mater margin and basal tissue, and sentinel lymph nodes showed completely negative. Defects in 3 elderly patients were repaired by single or multiple axial scalp vascular network flaps, with the resected flaps size ranged from 12 cm×7 cm to 19 cm×14 cm. Defects in the other 18 patients were repaired by anterolateral thigh perforator flaps with fascia lata, with the resected flaps size ranged from 13 cm×10 cm to 23 cm×19 cm and the resected fascia lata size ranged from 8 cm×7 cm to 10 cm×10 cm. The head donor site of flap was repaired by medium thickness skin of head and back; the thigh donor site of flap was repaired by medium thickness skin of thigh on the same side. All patients gave up postoperative radiotherapy, chemotherapy, and other follow-up treatments. Results: After operation, the flap and skin in all patients survived completely, with no vascular crisis or other condition. During the follow-up for 6 months to 9 years, all patients showed good appearance except for baldness in operation area of head, with no obvious malformation in head donor site of flap and skin, no swollen external hernia in the brain tissue, and no local recurrence or distant metastasis of carcinoma. The appearance of thigh donor site of flap and skin was good, with normal muscle strength and movement of lower limbs. Conclusions Patients with scalp carcinoma were performed with radical resection of carcinoma, and axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata were applied to repair the postoperative defects, with good appearance of head operation area and no local recurrence or distant metastasis of carcinoma.

Aim To study effects of loganin and morro-niside on aging astrocytes induced by D-galactose. Methods Cortex astrocytes of newly born rats were cultured in vivo and indentified by immunofluorescence method.Firstly,appropriate D-galactose concentration was selected and effects of loganin and morroniside on proliferation activity of aging astrocytes induced by D-galactose were determined by MTT test.Then SOD, MDA were taken as indicators to study the effects of loganin and morroniside on aging astrocytes induced by D-galactose.Thirdly,growth factors like gliar cell line-derived neurotrophic factor (GDNF),basic fibro-blast growth factor (bFGF)tested by ELISA method and expression of Bax,caspase-3,phospho-extracellu-lar signal-regulated kinese (p-ERK1 /2),phospho-mi-togen-actived protein kinase /extracellular signal-regu-lated kinase kinase (p-MEK1 /2)were taken as indi-cators to discuss the potential protection mechanism. Results Loganin and morroniside exerted certain effects on proliferation of aging astrocytes induced by D-galactose,improving SOD,GDNF,bFGF release and lowering MDA release significantly (P <0.05 ). The expressions of Bax and caspase-3 proteins had no difference between model group and loganin group, morroniside group.While the expressions of p-ERK1 /2,p-MEK1 /2 of loganin group,morroniside group were improved significantly compared with model group.Conclusion Loganin and morroniside have protective effects on aging astrocytes induced by D-ga-lactose,and increase the proliferation ability.Protec-ting their antioxidant systems and improving the expres-sion of p-ERK1 /2,p-MEK1 /2 proteins are possible mechanisms.

Objective To investigate the clinical effects of transurenthral resection of muscleinvasive bladder tumor (TURBT) in senile. Methods This study was clinical prospective random research.46 senile cases with muscle-invasive bladder cancer treated by TURBT was divided into 2 groups:control group and observed group.The observed group was treated with TURBT combined with intravesical instillation of pirarubi 30 mg immediately after TURBT,the bladder wall around tumor was resected thoroughly.The control group underwent radical cystectomy and pelvic lymph node dissection. Results The clinical improvement rate was higher in observed group than control group (85.7％ s.63.6％,X2 =5.3008,P=0.021).There was not difference in 3 years recurrence rate between observed group(25.0％) and control group(13.6％) (x2 =S.3008,P＞0.05).The 1 year survival rate were 95.8％,90.9％ and 3 years survival rate were 79.2％,72.7％ in observed group and control group,respectively,and there were no differences between the two groups(X2 =0.262,P=0.609). Conclusions TURBT combined with intravesical instillation of pirarubi can enhance clinical effect and reduce recurrence rate in the treatment of the elderly with muscle-invasive bladder cancer.

OBJECTIVE:To observe the effects of felodipine on blood vessel endothelial function in patients with benign prostatic hyperplasia(BPH) complicating essential hypertension(EH).METHODS:Fifty five patients with BPH complicating EH were assigned to receive 5mg felodipine orally qd for 6 weeks,with levels of endothelin-1(ET-1),nitrous oxide(NO) and von Wilebrand factor(vWF),brachial artery flow-mediated dilatation(FMD) function,the maximum urine flow rate,the average urine flow rate and International Prostate Symptom Score(I-PSS) determined before and after treatment.Meanwhile levels of ET-1,NO and vWF and FMD in 37 normal healthy males were determined.RESULTS:In the treatment group compared with normal control group there were significant differences in levels of ET-1,NO and vWF and FMD(P0.05).There were significant differences in ET-1,NO and vWF levels and FMD after treatment as compared with before treatment(P

Objective:To explore the influence ofDan Shou Tang to fetal loss induced by APA.Methods:One hundred of10-week pregnant SD rats were divided randomly into two groups, every group were divided randomly into nourishing kidney and promoting blood flow group A, nourishing kidney group B, promoting blood flow group C, group D-APS model group and group E--blank control group.From the first day ofpregnancy, the rats in group A were given Dan Shou Tang through intragastric administration;the rats in group B were given formula to nourish kidney and rats in group C were given formula to promote blood flow, while group D and group E, as the control were given the corresponding physiological brine through intragastric administration.Then on the eighth and the twelfth day ofpregnancy, all rats ofgroup A, B, C and D were given multi-site subcutaneous injecting ofpurified ACA-IgG or LA-IgG with a dosage of15mg/ml, fats ofgroup E were injected the corresponding physiological brine.On the 15th day ofpregnancy, the rats were killed for samples.Results:Compared with APS model group, fetal absorptivity, ACA and APTT level were dramatically decreased in group A, B and C(P
