OBJECTIVETo sum up the experience in diagnosis and treatment of Fournier's gangrene and find an optimal evaluation tool for its prognosis by comparing currently used prognostic scoring systems.

METHODSWe retrospectively analyzed 16 cases of Fournier's gangrene diagnosed and surgically treated in our hospital between 2004 and 2012. Using Fournier's Gangrene Severity Index (FGSI), Uludag Fournier's Gangrene Severity Index (UFGSI), Age-Adjusted Charlson Comorbidity Index (ACCI), and Surgical Apgar Score (sAPGAR) , we obtained the prognostic scores of the patients and made comparisons among different scoring systems.

RESULTSFGSI, UFGSI, ACCI, and sAPGAR were all clinically used scoring systems. Statistically significant differences were found in the scores of ACCI and UFGSI but not in those of FGSI and sAPGAR between the death and survival groups, with the maximum area under the ROC curve and minimum standard error for the ACCI score.

CONCLUSIONBoth ACCI and UFGSI are useful for evaluating the prognosis of Fournier's gangrene. However, ACCI is even better for its higher sensitivity and specificity and easier clinical collection.

Objective To investigate the changes of expression of Fas-associated proteins named Fas-associated death domain protein(FADD)and death-associated protein(Daxx)in the ischemic penumbra following transient focal cerebra ischemia in rats.Methods ①Adult male Sprague-Dawley rats were randomly divided into the sham-operated group and the cerebral ischemia model group.Rats underwent right middle cerebral artery occlusion(MCAO)for 2 h and reperfusion for 1,3,6,12 and 24 h using an intraluminal suture technique.The expression of FADD and Daxx mRNA and protein were measured with methods of immunohistochemistry.Western blot and reverse transcription-polymerase chain reaction(RT- PCR)respectively were used in the ischemic penumbra of rats.②Double-label fluorescence confocal laser scanning microscopy(CLSM)was performed to monitor FADD and Daxx intracellular location before and after ischemia.Results RT-PCR,Immunohistochemistry,Western blot experiments indicated that a very low level of FADD mRNA and protein were detected in the cerebral cortex of sham rats.The expression level both of FADD mRNA and protein increased significantly at 3 h after reperfusion,peaked at 12 h,then declined markedly at 24 h in the ischemic penumbra of model rats.RT-PCR,Immunohistochemistry indicated that a relatively high level of Daxx mRNA was detected in the cerebral cotex of sham rats.The expression level of Daxx mRNA increased significantly at 3 h after reperfusion and persisted to 24 h at a high level,whose protein had a same change of expression level in the ischemic penumbra of model rats. Immunofluorescence double-staining laser scanning by CLSM showed that the immunoreactivity of FADD was located in cytoplasm,and the intracellular translocation of the immunoreactivity of Daxx from nucleus to cytoplasm was monitored by measuring the green fluorescence after ischemia.Conclusion The transient upregulation of FADD and the persistant high level of expression of Daxx may contribute to neuronal apoptosis following cerebral ischemia/reperfusion.

Objective To establish a method for rapidly detecting the G-protein ?3 subunit (GNB3) 825 site single nucleotide polymorphism (SNP) and to analyse the relationship between GNB3 825 site gene SNP and obesity. Methods The real-time fluorescent PCR was employed to analyse the GNB3 825 site gene SNP of 420 samples from 21 provinces and the the frequencies of genotypes were compared with those detected by gene sequencing. GNB3 825 site genotype, body weight, body mass index (BMI) and fat content were examined from 207 subjects and the correlation between GNB3 825 site gene SNP and obesity was analysed. Results The result by real-time fluorescent PCR showed that the frequencies of 825T and 825C haploid were 46.90% and 53.10%, respectively, and the frequencies of 825TT, 825TC and 825CC genotype were 22.38%, 51.42% and 28.10%, respectively, with no other genotype detected, which was consistent with the result by gene sequencing. BMI and fat content were significantly higher in subjects with GNB3 825TT than in subjects with other genotypes. Body weight was much higher in subjects with GNB3 825TT genotype than in subjects with 825CC genotype, but not significantly different with 825CT genotype. Conclusion A new rapid method for the detection of GNB3 825 site SNP has been successfully established. There existed significant correlation between GNB3 825TT genotype and obesity.

AIM: To observe the efficacy and safety of intravitreal injection of Conbercept for the treatment of wet age-related macular degeneration( AMD) .
METHODS:Retrospective analysis. A total of 20 patients involving 22 eyes were diagnosed of wet AMD and confirmed by routine ophthalmic examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography. All these affected eyes received intravitreal injection of 10 mg/ml of 0. 5mg Conbercept, once monthly, for 3 successive times during the initial treatment. The need for repeated treatment was determined according to patients'disease conditions. The patients were followed up once monthly for ≥6mo. The changes in best corrected visual acuity ( BCVA ) , central retinal thickness ( CRT ) and choroidal neovascularization ( CNV) lesion leakage of the affected eyes before and after treatment were compared and analyzed.
RESULTS:Within 1, 3 and 6mo after treatment, the mean BCVA ( logMAR ) of the affected eyes increased when compared with before treatment;the difference was statistically significant(P<0. 01). In 1, 3 and 6mo after treatment, the mean CRT of the affected eyes decreased when compared with before treatment;the difference was statistically significant(P<0. 01). During the last follow-up, FFA showed that macular CNV lesion leakage disappeared in 20 eyes(90%) while leakage mitigated in 2 eyes ( 9%) . During the follow - up, there were no treatment - related serious ocular complications and systemic serious adverse reactions.
CONCLUSION: Clinically, intravitreal injection of Conbercept for the treatment of wet AMD can increase visual acuity of the affected eyes. It also can decrease CRT of the affected eyes, and inhibit neovascular leakage. There are no treatment-related adverse reactions.
