Suspension array technology,a bead-based multiplex assay,allows a fast and automatic detection of multi-analytes and batch samples in limited sample volume,and it is great potential clinical application in the determination of autoimmune antibodies,muhitumor markers,the phenotype of Human Leukocyte Antigen and the genes of infectious pathogens.However,currently,there are various limitations which hinder the clinical application of this technology broadly.The globally accepted panel of multi analytes,performance criteria,and quality control programs should be established before we get benefit from this high throughput,sensitivity and repeatability platform,which will help to provide scientific and accurate laboratory data for the clinical diagnosis,treatment and prevention.

Objective To summarize the preliminary experience of coils, Onyx and covered stents for the treatment of carotid-cavernous sinus fistula (CCF). Methods Of the 25patients with CCF, 22 were traumatic CCF, and 3 were spontaneous CCF; the fistula orifices of 14 patients were located in the cavernous segment of right internal carotid artery (ICA), and 11were located in the cavernous segment of left ICA. According to the Barrow classification,Types A, C, and D were 22,2, and 1, respectively. Eighteen patients were treated with Guglielmi detachable coils alone, 1 was treated with Guglielmi detachable coils and Onyx, 2 were treated with Onyx alone, and 4 were treated with covered stents. Results Intracranial bruit disappeared immediately in all patients after the procedures. Postoperative angiography showed complete occlusion of the fistula orifices, the symptoms disappeared after 1 to 20 days, and there were no death and procedure-related complications. The recanalized ICAs were patent in patients (12/18) treated with coils, and the ICAs were patent in 4 patients treated with the covered stents.The ICAs were patent in 2 patients treated with Onyx, the ICA was patent in 1 patent treated with detachable coils and Onyx. One patient with traumatic CCF treated with coils had clinical recurrence, and was cured after re-embolization with coils. The remaining patients were followed-up for 6 to 24 months, and no recurrence of clinical symptoms was found. The followup cerebral angiography of 6 patients was obtained, and no CCF recurrence was observed.Conclusion Endovascular treatment with Guglielmi detachable coils, Onyx, and covered stents is a safe and useful method for closing CCFs.

Objective To investigate the feasibility and efficacy of tunica vaginalis flap cover in treatment of recurrent urethrocutaneous fistula (UCF).Methods We reviewed the clinical datas of 25 cases of UCF after urethroplasty of hypospadias from January 2011 to January 2015.The mean age of the patients was 6.2 years(range 1.6-14.0 years).All patients had undergone previous hypospadias repair and at least one previous failed attempt to close the urethrocutaneous fistulae.There were 5 cases of fistula in the coronary sulcus,6 cases of fistula in the penile body and 14 cases of fistula at the junction of penis and scrotum.The diameter of urethrocutaneous fistulae were 3-10 mm.Single fistula was present in all patients.16 cases had undergone UCF repair for two times, 9 cases had undergone UCF repair for more than two times.After closing the fistula with inverting running stitch, a tunica vaginalis flap was mobilized to cover the repair site through a subcutaneous tunnel and the skin closed.Results The mean follow-up time was 2.1 years(range 0.5-4 years).The overall success rate was 96％ (24/25).Penile cosmesis was excellent.There was no evidence of recurrent fistulas or urethral strictures.All parents reported a straight penis when erected, and one patient in whom there was leak from the fistula site because of local wound infection.No postoperative complication was encountered in the testis.The testis was of normal size and position, and the ultrasound findings were normal.Conclusions Repairment of recurrent urethrocutaneous fistulas with a tunica vaginalis flap could be effective regardless of fistula location.The technique is simple to improve the success rate of the repair of UCF effectively and reduce the occurrence of postoperative complications.

OBJECTIVE: To observe the changes of peristalsis of small intestine in guinea pigs after administration of traditional Chinese medicines activating blood to resolve stasis (Compound Danshen Decoction, CDSD) or/and medicines dredging intestines (Dachengqi Decoction, DCQD), and to explore the synergetic or intensive effect of CDSD on DCQD. METHODS: By means of BL-420 Biological Experimental System, peristalsis of small intestine was recorded and analyzed following administration of DCQD, CDSD or Huoxue Chengqi Decoction (HXCQD, compound of CDSD and DCQD) respectively in different experimental periods. RESULTS: The amplitude and frequency of intestinal peristaltic wave obviously increased following administration of the three decoctions, but HXCQD appeared to be most dominantly. CONCLUSION: The effect of DCQD can be further enhanced by combining use of CDSD, suggesting that the traditional Chinese medicines activating blood to resolve stasis have an intensive effect on medicines dredging intestines.

OBJECTIVE: To investigate the audiologic characteristics of the children with cleft lip and/or palate. METHOD: Sixty-two children with cleft lip/palate were enrolled in the study. Tympanometry, DPOAE, ABR were tested in all the chidren. RESULT: Regarding the ABR threshold as the diagnostic criteria, 51 (41.13%) ears had hearing loss, mainly moderate. Sixty-three (59.43%) ears had abnormal tympanometry, which meant the disorder function of the middle ear. Twenty-six (56.52%) ears didn't pass the DPOAE. CONCLUSION The proportion of the hearingloss in the children with cleft lip/palate was large. There was a good coherence among the three objective examinations when assess the children with cleft lip/palate.

OBJECTIVE To explore the best method of cleaning and sterilization of laparoscopic apparatus.METHODS Laparoscopic apparatus useed in the hospital was divided into four groups at random:with artificial cleaning and sterilization by ethylene oxide(EO),with machine-cleaning and sterilization by EO,with artificial cleaning by hydrogen peroxide plasma,and with machine-cleaning and sterilization by hydrogen peroxide plasma.And The sterilization effect of four groups was observed.RESULTS The positive cleaning result of manual with ultrasonic cleaning was 97.5%,but with autowash cleaner was 73.3%.The rate of qualification of artificial-groups was higher than machine groups obviously(P

Objective To evaluate the clinical application of selective renal artery embolization (SRAE) for the treatment of kidney diseases. Methods Seventy-four cases of renal carcinomas, 11 cases of renal angiomyolipomas (RAML) and 72 cases of traumatic renal haemorrhages were first demonstrated by renal arteriography under Seldinger technique to ensure a site, range and neighbouring relation of lesions and then followed by percutaneous catheterized selective renal arterial embolization with embolic agents. Results The edema around the carcinomas and abscesses became obvious, and bleeding were reduced, which were convenient for operation after SRAE for the preoperative adjuvant treatment of renal carcinomas. The clinical symptoms were improved obviously in 9 eases with advanced renal carcinoma after palliative treatment. The tumour volumes of 11 RAML were decreased evidently by 15 %-65 % with the average of 42 %. The bleeding in 68 cases of traumatic renal haemorrhage were ceased completely in 1-4 days after embolism, 2 cases with serious renal fragmented injury and huge perirenal hematoma combined with shock received successful operation after SRAE, 2 cases bleeding again after SRAE were cured by the second SRAE. No severe complications occurred after embolization in all the patients. Conclusions As a minimal invasive technique,selective renal artery embolization is a safe, effective method with less complications and an adjuvant pre-op-erative therapy for renal carcinoma or a palliative treatment for advanced carcinoma and an effective treatment for RAML and traumatic renal haemorrhage.

Objective To evaluate super-selective renal arterial embolization(SRAE)in treating severe renal hemorrhage when conservative treatment had failed. Methods SRAE was performed in 111 patients with severe renal hemorrhage who had failed to respond the conservative management.The clinical data,the way of embolization,the medication and the follow-up findings were retrospectively analyzed.Results Excellent results were obtained in all patients after SRAE and no serious complications occurred.The technical successful rate with single session was 95.5%(106/111).Gross hematuria disappeared within 1-4 days after the treatment.Two patients developed shock after renal embolization and had to receive surgery after the shock was controlled.Three patients had a recurrence of hematuria,the blood urine subsided after SRAE was employed again.A follow-up with a mean period of 37.4 months was carried out in 92 patients,and the follow-up checkups showed that the renal function was well preserved in all patients.Conclusion Super-selective renal artery catheterization and embolization is a safe and effective treatment for severe renal hemorrhage,it can maximally preserve the healthy renal parenchyma as well as the renal function.Therefore,this technique should be regarded as the treatment of first choice for patients with severe renal hemorrhage.

Objective To observe the changes of diffusion weighted imaging (DWI) after diffuse axonal injury (DAI) in rats. Methods Models of various degrees of DAI (mild, moderate and severe) were established in 135 SD rats by Marmarou method, and MRI examinations were performed 4, 8 and 24 h after injury. Another 8 rats were served as control group. The findings of MRI were analysed, and the apparent diffusion coefficient (ADC) values were compared among each group. Results No clear traumatic lesion was found from MRI in rats after injury. Four hours after injury, ADC values decreased in each DAI group, and there were significant differences between moderate DAI group and control group, and between severe DAI group and control group (P<0.05). Eight hours after injury, ADC values increased in each DAI group, and there was no significant difference between DAI groups and control group (P>0.05). There were significant differences in ADC values between 8 h after injury and 4 h after injury in severe DAI group (P<0.05), while there was no significant difference in moderate and mild DAI groups (P>0.05). Twenty-four hours after injury, ADC values continuously increased, especially in severe trauma group. Conclusion ADC values may reveal traumatic changes that can not be demonstrated by MRI. ADC values decrease in acute phase of DAI in rats, then increased, and the degree of variation may be related to the severity of DAI.

Objective To evaluate the embolic effect on rabbits arteries using self-made copper plated platinum coil.Methods 1 7 New Zealand Big Ear Rabbits were selected.Unilateral subclavian artery or carotid artery was embolized with self-made secondary level copper plated platinum micro-coils (experimental group)through 3F-catheter.Contralateral subclavian artery or carotid artery was also embolized using secondary level platinum micro-coils (control group)as a control.The level of serum copper ions and the liver and renal function were recorded during different intervals before and after embolization.The arteriography and the tissue his-tology were observed respectively during different intervals after the embolization.Results 1 5 of 1 7 rabbits were embolized success-fully.After embolization,the level of serum copper ions increased in 2 weeks(P <0.05).However,it returned to preoperative level after 4 weeks (P >0.05).The liver and renal function was similar to that of the preoperation after 2 weeks.After embolization,an-giography showed that vascular embolization effect between two groups was not significantly different at 10 min and 30 min;howev-er,the embolization effect of experimental group was superior to that of control one (P <0.01)at 3 days and 1 week,2 weeks,4 weeks,6 weeks and 12 weeks.Pathological results showed that there were a lot of thromboses inside,outside and around the copper coil.Few thromboses appeared around platinum coil in control group.The thrombosis situation in experiment group was better than that in control one (P <0.01).However,no significant difference in inflammatory cell infiltration between two groups was found. Conclusion Self-made secondary level copper plated platinum coil has good physical property,rememorability,flexibility and con-trollability.
