Objective To evaluate clinical significance of monitoring noninvasive intracranial pressure (NICP) and cerebral perfusion pressure (CPP) in treatment of patients with hypertensive intracerebral hemorrhage. Methods This clinical randomized controlled trial enrolled 120 patients with hypertensive intracerebral hemorrhage who had sought medical treatment in our department from June 2008 through May 2010. They were randomized equally into a monitoring group where NICP and CPP were continuously monitored before and after operation and a non-monitoring group where no monitoring of NICP and CPP was performed. Results In the monitoring group,increased NICP and decreased CPP were shown in 50 patients and only 10 patients were shown with normal NICP (＜26.6mmHg) and CPP (＞ 124.3 mm Hg). The abnormal NICP and CPP continuously monitored were treated with specific interventions like further operation or medication. In the non-monitoring group,patients received only conventional treatments.According to the Glasgow Outcome Scale (GOS), 31 patients (51.7％) had good recovery,20 (33.3％) were moderately disabled,5 (8.3％) severely disabled and 4 (6.7％) dead in the monitoring group while 23 (38.3％) patients had good recovery,18 (30.0％)were moderately disabled,10 (16.7％) severely disabled and 9 (15.0％) dead in the non-monitoring group.The outcomes of the monitoring group were significantly better than those of the non-monitoring group (P＜0.05). Conclusion Continuous monitoring of NICP and CPP before and after operation should be performed in the treatment of patients with hypertensive intracerebral hemorrhage because it is helpful for clinical medication and reducing complications and mortality as well.

OBJECTIVETo evaluate the methods of repairing urethral fistula resulting from hypospadias operation.

METHODSWe analyzed the clinical data of 46 cases of surgical repair of urethral fistula resulting from hypospadias operation. The patients ranged in age from 3 to 26 (mean 11.7) years. There were 52 fistulas in all, with the diameters of less than 5 mm, of which 25 were in the midshaft of the penis, 12 in the penoscrotum, and 9 in the scrotum. Of the 46 cases, 20 were repaired by continuous knock suture and 26 by tunica vaginalis of testis and spermatic fascia.

RESULTSThe one-stage success rate of continuous knock suture repair was 55% (11/20) and that of the combined use of continuous knock suture with tunica vaginalis of testis and spermatic fascia repair was 84.6% (22/26).

CONCLUSIONBased on continuous knock suture, the additional use of tunica vaginalis of testis and spermatic fascia yields a high success rate in repairing urethral fistula resulting from hypospadias operation.

To establish the high performance liquid chromatography (HPLC) fingerprint for Digeda-4 decoction (DGD-4D), determine the contents of aesculetin, geniposide, picroside Ⅰ, picroside Ⅱ and ellagicacid in DGD-4D, and provide the scientific foundation for quality control of DGD-4D. The analysis was performed on Diamonsil(2) C₁₈ (4.6 mm×250 mm,5 μm) column, with methanol-0.1% phosphoric acid aqueous solution as mobile phase for gradient elution. The flow rate was 1.0 mL·min⁻¹; injection size was 10 μL; temperature was maintained at 30 °C, and the detection wavelength was set at 254 nm. The common mode of DGD-4D HPLC fingerprint was established, and the hidden information was analyzed by Chemometrics. Chromatographic peaks for DGD-4D were identified by HPLC and quantitative analysis was conducted for characteristic peaks. There were 17 common peaks in the fingerprints and the similarity of the fingerprints was over 0.9 in all 15 batches. The samples were broadly divided into four kinds by principal component analysis and clustering analysis. Four marker compounds were verified by partial least squares discriminant analysis, and No. 9, 12 and 14 peaks were identified as geniposide, picroside Ⅱ, and picroside Ⅰ respectively. The average recoveries were in the range of 95.91%-97.31%. The HPLC fingerprint method for content determination is reliable, accurate, rapid, simple, and reproducible, and can be used as one of the effective methods to control the quality of DGD-4D.
