Objective To evaluate the in vitro activity of seven imidazole antifungals against clinical isolates of common Candida species.Methods According to the Clinical and Laboratory Standards Institute (CLSI) microdilution method M27-A3,the in vitro activity of luliconazole,ketoconazole,miconazole,econazole,clotrimazole,sertaconazole and bifonazole was determined among 183 clinical isolates belonging to 5 species of Candida.Results The minimal inhibitory concentration range was 0.03-8 (geometric mean:0.067) mg/L for ketoconazole,0.03-16 (geometric mean:0.071 ) mg/L for miconazole,0.03-8 (geometric mean:0.207) mg/L for econazole,0.03-8 (geometric mean:0.061 ) mg/L for clotrimazole,0.03-16 (geometric mean:0.187) mg/L for sertaconazole and 0.03 -＞16 (geometric mean:1.050) mg/L for bifonazole. Luliconazole exhibited a superior activity against the 5 species of Candida in vitro,with the MIC range being 0.03-8 mg/L,geometric mean MIC 0.087 mg/L,MIC50 0.06 mg/L and MIC90 0.5 mg/L,respectively.However,some Candida isolates were identified to be relatively insensitive to these tested antifungals,including luliconazole.Conclusion All the tested imidazole antifungals,except for bifonazole,show an excellent activity against Candida species in vitro,but there exist a few Candida strains with relative insensitivity.

ObjectiveTo dynamically observe the paradoxical effect (inhibitory at low concentratin but promotive at high concentration) of caspofungin and micafungin across Candida species in vitro.MethodsA broth microdilution testing was performed following the Clinical and Laboratory Standards Institute(CLSI) M27-A2 document to observe the paradoxical effect of caspofungin and micafungin across 85 Candida strains.The growth of Candida was observed on a daily basis for 7 days.ResultsAt 48 hours,the prevalence of paradoxical growth in C.albicans,C.glabrata,C.parapsilosis,C.tropicalis,C.dubliniensis and other species of Candida was 90％,20％,41.7％,37.5％,33.3％ and 28.6％ respectively after caspofungin treatment,and 5％,0,0,25％,33.3％and 0 respectively after micafungin treatment.The concentration range of caspofungin required for the paradoxical growth of C.albicans,C.glabrata,C.parapsilosis,C.tropicalis,C.dubliniensis and other species of Candida was 4-16,8-32,8-32,2-8,2-8,8-32 μg/ml respectively,and that of micafungin for the paradoxical growth of C.albicans,C.tropicalis and C.dubliniensis was 4-16,4-32 and 1-8 μg/ml,respectively.After 48 hours,the prevalence of paradoxical growth still increased in C.parapsilosis,C.glabrata,and other species of Candida following caspofungin treatment,and in C.albicans and C.glabrata following micafungin treatment.ConclusionsThe occurrence,and time of occurrence,of paradoxical effect of echinocandins is Candida speciesand drug-specific.The prevalence of paradoxical effect is higher for caspofungin than for micafungin,which seems unrelated to their MICs against Candida species.

5 mm and ≤8 mm in 4 cases.The mean value was 4.2 mm. Four patients noticed reduction in their vision and two had diplopia.Those patients were examined by CT or MR.Direct venography was performed in each patient.After the diagnosis of OVM was confirmed, intralesional injection of BLE was performed.The efficacy of the treatment and complications were observed during the following 8 to 42 months(mean 23 months).Results The BLE were successfully injected in all the patients.All patients had resolution of proptosis and diplopia.Three patients gained improvement of visual acuity.The periorbital swelling occurred in all patients after operation and resolved within 1 week without special treatment.Other complications,such as orbital hemorrhage and periorbital scar,were not observed during following-up.Conclusion Intralesional injection with BLE is convenient,safe and efficient for the treatment of OVM.

OBJECTIVETo evaluate the results of the surgical treatment of patients with Budd-Chiari syndrome (BCS).

METHODSThe clinic data of 120 BCS patients who underwent various consecutive surgical treatments from July 2001 to October 2010 was analyzed. There were 82 male and 38 female patients, aging from 11 to 72 years with a mean age of (41 ± 13) years. All patients experienced various examinations to identify the pathological type of BCS. There were 5 cases of small hepatic veins type, 28 cases of large hepatic veins (LHV) type, 31 cases of inferior vena cava (IVC) type and 56 cases of combined obstruction of LHV and IVC. Totally, 25 patients experienced interventional treatment, include percutaneous transluminal angioplasty and/or stenting for stenosis of hepatic vein and/or IVC, 77 patients experienced open-thorax operation for BCS radical resection under protection of right atrium by-pass with extracorporeal circulation.

RESULTSTotally 97 cases were followed up from 1 to 120 months after various surgical treatment methods. Perioperative mortality was 6.2% (6/97). Follow-up period mortality was 8.2% (8/97). The restenosis of IVC and/or hepatic vein happened in 3 cases out of 25 cases in intervention treatment group in contrast with 15 cases out of 77 cases in radical resection group. The 5-year patency and survival rate of IVC/hepatic vein were 64.5% and 83.3%.

CONCLUSIONSThe surgical treatment of BCS need to get accurate diagnosis and pathological classification firstly, then, to choose appropriate therapeutic strategies based on individual pathological classification. The BCS radical resection can be an alternative method in some particular pathological classifications and the cases who failed in interventional treatment.

OBJECTIVETo evaluate the effect of the transverse preputial island flap technique (Duckett's procedure) for hypospadias repair.

METHODSA total of 356 patients with hypospadias were treated by Duckett's procedure from March 1995 to December 2010, of whom 324 (91.0%) were younger than 14 years. The length of urethra repair ranged from 1.5 to 10 cm.

RESULTSThe total success rate of Duckett's procedure was 91.0%. Urethra fistula occurred in 30 cases, external orifice stricture in 1, and urethral anastomosis stricture in another. There were no significant differences in the rate of complications among either different age groups or different surgical times (P > 0.05).

CONCLUSIONDuckett's procedure remains the first choice for the one-stage repair of hypospadias, especially applicable to hypospadias with chordee.

OBJECTIVETo evaluate the feasibility of no antibiotic administration to prevent infection during the perioperative period of percutaneous intradiscal ozone-injection for treatment of lumbar disc herniation.

METHODSSeventy-two patients with lumbar disc herniation but normal body temperature as well as normal results of three routine tests (blood, urine, stool) and C-reactive protein (CRP) level were randomly divided into two groups. The patients in prophylaxis group were given cephalothin V(2.0 g) intravenous 30 min before the operation, and the control group did not use any antibiotics. All the patients were injected with 6-10 ml ozone (40 microg/ml) for medical use into the discs with 21G needles under fluoroscopic guidance, followed by 10 ml ozone into the paravertebral space. Three days later the general examinations and CRP measurement were repeated.

RESULTSNo infection was found in these patients, nor were any significant differences noted in the results of the examinations between the two groups after controlling in patients with above-normal white blood cell count, neutrophil percentage and CRP level.

CONCLUSIONProphylaxis antibiotics is not necessary during the perioperative period of percutaneous intradiscal ozone injection for lumbar disc herniation.

OBJECTIVETo clone a novel human testis-specific gene TDRG1.

METHODSA new contig of expression sequence tags (ESTs) Hs.180197 was identified from the testis libraries using digital differential display (DDD) to screen the novel human testis-specific gene. To validate the use of bioinformatics approaches in gene discovery, the ESTs Hs.180197, which was predicted to be testis specific, was chosen for further study. Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed on different normal tissues to identify the expression of Hs.180197 in human testis. Using bioinformatics methods and IMAGE cloning of this contig, the full-length cDNA sequence of the noval human gene was cloned.

RESULTSThis novel gene was 1197 bp in length, located in chromosome 6p21.1-p21.2. The sequence of the open reading frame was 504-806 bp, as confirmed by RT-PCR and sequencing in human testis. The cDNA encodes a novel protein of 100 amino acids with a theoretical molecular weight of 10 000 and isoelectric point of 6.81. The sequence shares no significant homology with any known protein in the databases. Semi-quantitative RT-PCR analysis of multiple tissues further showed that the novel gene was expressed specifically in adult human testis. Considering a possible relation of this novel gene with the function of human testis, we named this new gene TDRG1 (testis development related gene 1, GenBank accession number: DQ168992).

CONCLUSIONDDD combined with laboratory validation is an efficient method for identifying new human functional genes.
