Objective To compare and analysis two different surgical treatments for hypertensive basal ganglia hemorrhage.Methods 68 patients with hypertensive basal ganglia hemorrhage with no brain hernia received small window craniotomy microsurgery and aspiration. 24 patients received conservative treatment as the control group in the same time,who didn't accepted the surgery.Results Two groups of surgical treatments were better than the control group in aspect of effective rate,functional recover and mortality. And the rebleeding rate and complication incidence in acute-time had no difference.There were no difference in aspect of effective rate,average stay,functional recover and mortality between the two groups of surgical treatments. Conclusion Small window craniotomy microsurgery and aspiration had same effect on hypertensive basal ganglia hemorrhage. We can choice the method of operation according to the case.

To analyze the cause and therapy of hydrops in subcutaneous scalp after repairing skull defect by using silicon-polyester fiber network, a total of 91 patients who were treated with silicon-polyester fiber network to repair skull defect from June 1996 to October 2000 in the Department of Neurosurgery, Nanshan People's Hospital were analyzed retrospectively. And 56 cases of them had hydrops of subcutaneous scalp and treated with suction and pressure dressing, including 11 cases of less than 20 mL hydrop quantity, 27 cases of 20-50 mL, and 18 cases of more than 50 mL. They were observed for 6 weeks averagely after operation and were healed within 4 weeks by simple management. No recurrence of hydrops was found in subcutaneous scalp. It is indicated that silicon-polyester fiber network in repair of skull defect may complicate with hydrops of subcutaneous scalp usually. However, the prognosis will be good by means of drainage, so it can be used as a therapy for skull defect.

Objective To explore the effect of aspiration of hematoma on the serum neuron-specific enolase(NSE)concentration in patients with hypertensive intracerebral hemorrhage and its clinical meaning.Methods 45 cases of intracerebral hemorrhage with hematoma volumes of 30ml to 50ml were selected and divided into operative group(23 cases)and conservative group(22cases).The control group(18 cases)were healthy.Serum NSE was detected with ELISA method.Results ①The concentration of NSE in conservative group was obviously higher than that in control group within 21 days(P0.05).③The concentration of NSE in operative group was no significant difference than that in conservative group with in 7 days,but decreaced rapidly and was obviously lower than that in conservative group respectively in 14 days and 21 days(P

Objective:To screen the peptide binding to human bladder carcinoma cells specifically by using phage display technology in vivo.Methods: Nude mice were inoculated with bladder carcinoma cells BIU87 for establishing tumor-bearing mice model.The Ph.D.-C7CTM Peptide Library was injected intravenously via tail vein.Then we screened Phage containing exogenous peptides binding to bladder transitional carcinoma cells specifically.The phage peptide homed to the tumor tissues was obtained after 3 rounds screening in vivo.The phage clones affinity to BIU87 were identified by immunohistochemistry and ELISA.The positive peptide was synthetized by chemical methods after sequencing the positive monoclonal phage DNA.The tumor cell specificity of target peptide was identified by confocal laser scanning microscope and flow cytometry.Results:After 3 rounds screening in vivo,enrichment rate of phage was 4.334×102 times.Immunohistochemistry results showed that the dyeing of the tumor tissue had a rising trend following each round of phage screening,while liver had a lot of non-specific binding phage because the phages were metabolized through liver and kid-ney.The 30 phage clones were identified by ELISA and 10 clones had a strong affinity on BIU87 among 24 positive clones.Three amino acid sequences of positive phage clones were obtained.The highest rate of repeat sequences CSSPIGRHC(8/10) named NYZL1 and the FITC-C6-NYZL1 peptide was synthesized.Our results showed that it could bind to bladder carcinoma cells BIU87 specifically.Conclusion:We obtained the small molecular peptide NYZL1 binding to human bladder carcinoma specifically by means of phage display in vivo,which provide a theoretical basis for bladder carcinoma early diagnosis and targeted therapy.

Objective To evaluate the clinical outcomes of different flaps for repairing the soft tissue defects of heels.Methods A total of 26 patients with soft tissue defects around the heel treated modified propeller perforator flap,medialis pedis flap,or anterolateral thigh flap from March 2012 to June 2016 were analyzed retrospectively.There included 19 males and 7 females,aged 4-64 years (mean,38.1 years).There were 9 patients with posterior heel defect,3 with weight-bearing defect,6 with posterior medial defect and 8 with posterolateral defect.The wound areas were from 6.0 cm × 4.0 cm to 12.0 cm × 9.5 cm,while the flap areas were from 7.0 cm × 5.0 cm to 13.5 cm × 10.5 cm.According to the principle of flap selection,the pedicled skin flap instead of free skin flap was selected in order to minimize damage to the donor site area.Modified propeller perforator flap was applied in 13 patients,medialis pedis flap in 3 patients and anterolateral thigh flap in 14 patients.The flap donor site was directly sutured in 23 patients and a simultaneous skin graft was applied in 3 patients.The survival rate,appearance,texture and feeling recovery of flaps,complications,walking ability,and the status of donor sites were compared.Besides,postoperative functions of all cases were estimated according to foot scoring scale of American Orthopaedic Foot and Ankle Society (AOFAS).Results All flaps survived well in 26 patients.The wounds of flaps and flap donor sites were healed at Ⅰ stage.A total of 24 patients were followed up for 12-36 months (average 16 months).The appearance,color and texture of the flaps were good.There was no ulcer in flaps or flap donor sites.The protective feeling of flaps was recovered and the feeling of distinguishing two points was 6-13 mm.Modified propeller perforator flap donor site was directly sutured,the wound of which showed a linear healing.There was no fat deformity or obvious scar formation around ankle.The skin graft of the medialis pedis flap donor site was healed well,without scar hyperplasia,rupture,or deformity of arch.The anterolateral thigh flap was healed linearly without scar,and the anterolateral skin felt slightly depressed.The muscle strength of the four biceps femoris muscle was 4.According to AOFAS score,the feet's functions were evaluated as excellent in 5,good in 16,fair in 4,and poor in 1,with excellence rate of 81％.Conclusions For different soft tissue defects of the heels,propeller perforators flap,medial plantar flap or anterolateral thigh flap can not only attain appearance reconstruction of the defects and good functional recovery,but also minimize the injury of flap donor site.

Objective To investigate the characters and targeted ability of FITC-CSNRDARRC molecular probe in labeling orthotopic transplantation tumor of bladder cancer in vivo.Methods From July 2013 to June 2014,the stability and characters of FITC-CSNRDARRC molecular probe were detected by spectrophotometer and molecular imaging and the optimum concentration and imaging time window were determined.30 BALB-C nude mice were randomly divided into experimental group (n =20) and control group(n =10).In control group,5 of them (group A) were ligated bilateral ureter,others(group B) were not.We established orthotropic transplanted bladder tumor (BIU-87) model by operation.And 0.2 ml probes (220 μmol/L) was then injected intravenously in all mice after 2 weeks.We obtained images and analyzed average gray value of the heart,lung,liver,spleen,bilateral kidney and orthotropic transplantation bladder tumor by using optical probe molecule fluorescence imaging system after 30 min,1 h,2 h,4 h and 12 h,respectively.Results After injected the FITC-CSNRDARRC molecular probes intravenously at 220 μmol/L,the fluorescence signal of tumor tissue strengthened gradually.The optimal imaging time window was 4 hours after injection.The illumination and temperature had little effect on the fluorescence signal.With the time passing after injection,the intensity of florescence signal progressively increasing,which reached the peak at4 h.The average gray value of tumor tissue at 1 h,2 h,3 h,4 h,5 h,6 h,8 h,12 h were 74.22,76.2,80.11,89.38,83.29,85.1,81.22,83.01,respectively.The fluorescence signal of normal tissue weakened gradually with the passage of time.Only liver and gall bladder could notice the fluorescence signal 4 hours after injection in group A.However,the relatively strong fluorescence signal could be found in liver and gall bladder in group B.Conclusions The characters of fluorescence probe are affected by its concentration.Its optimal concentration of labeling tumor is 220 μmol/L.The optical imaging time window was about 4 h after intravenous injection.The FITC-CSNRDARRC molecular probe can specifically bound to orthotopic transplanted tumor of bladder cancer in vivo.
