Objective To estimate the performance of Wood's lamp examination in the diagnosis of superficial cutaneous fungal infections. Methods Totally, 129 patients, who were diagnosed with superficial cutaneous fungal infections according to clinical medical history and signs, were enrolled in this study. Wood's lamp examination of lesions was carried out. Cutaneous samples were obtained from the patients and subjected to microscopic examination and fungal culture. Results Wood's lamp examination was positive in 84% and 85.7% of patients with tinea versicolor and malassezia folliculitis, respectively; among these patients positive for Wood's lamp examination, 92.9% were positive for fungal culture, and 87.5% for microscopic examination. In patients clinically diagnosed with tinea manus and pedis, tinea corporis or tinea cruris, 8.3% were positive for Wood's lamp examination, while 85.4% were positive for fungal examination. There was a high consistency between Wood's lamp examination and fungal examination in patients with tinea versicolor and malassezia folliculitis, but not in those with tinea manus and pedis, tinea corporis or tinea cruris. Conclusions Wood's lamp examination shows a high specificity and sensitivity and is useful in the diagnosis of tinea versicolor and malassezia folliculitis, but seems unapplicable for the diagnosis of tinea manus and pedis, tinea corporis or tinea cruris.

Objective Autologous hematopoietic stem cell transplantation (Auto-HSCT) has been widely used in hematological malignancies.To mobilize and harvest sufficient number of peripheral CD_(34)~+ cells is one of key issues for auto-HSCT. Peripheral CD_(34)~+ cell numeration has been used as an indicator for apheresis while we mostly rely on the peripheral WBC or MNC count. In this study, we try to evaluate the association of peripheral CD_(34)~+ count to the CD_(34)~+ cells number in the apheresis product and to find out a potential threshold. Methods From Jan 2007 to Dec 2009, a total of 57 apherosis for auto-HSCT were analysed. All patients were mobilized by cyclophophamide (CTX) plus G-CSF(5-10μg/kg) regimen. The apheresis were performed with COBE SPECTRA VERSION 6 and CD_(34)~+ count of both peripheral and apheresis products were analysed by flow cytometry. Results The median number of MNC in apheresis products was 4.6(0.3-10.5)×10~8/kg with median CD_(34)~+ cells at 2.4(0.16-34.9)×10~6/kg. The peripheral CD_(34)~+ count was the only parameter associated with the MNC and CD_(34)~+ cell numbers in the apheresis products while the WBC number was irrelevant to the results of apheresis. Our data showed that when the peripheral CD_(34)~+ count reach 15/μl, the efficacy of a single apheresis significantly improved with 81 % and 60 % reached 1 and 2×10~6 CD_(34)~+ cells/kg respectively and the total number of MNC and CD_(34)~+ cells were significantly superior to apheresis with peripheral CD_(34)~+ cells <15/μl, thus indicated that CD_(34)~+ ≥15 /μl can be used as the threshold for apheresis. Furthermore, the ROC analysis demonstrated that CD_(34)~+ cells ≥25(26.5-28.6) /μl is the best indicator level for a successful single apheresis. Conclusion Our study clearly showed that peripheral CD_(34)~+ cell count is a key indicator of apherosis. CD_(34)~+ cells at 15/μl can be used as the threshold to start apheresis in the clinical setting.

Objective:To evaluate the curative effect and safety of piperacillin/tazobactam in the treatment of children with con-genital gegacolon enteritis. Methods:122 cases of congenital intestinal enteritis were randomly divided into two groups. The 72 pa-tients in the treatment group were treated with piperacillin/tazobactam sodium, and the 50 patients in the control group were treated with cefoperazone/sulbactam. The course of treatment was 714 days. The differences in C-reactive proteins, bolld leukocytes count and neutrophilic granulocyte percentage before and after the treatment, and the average treatment time in both groups were compared, and the efficacy and bacterial clearance were evaluated. Results:Between the treatment group and the control group, the differences in C-reactive protein, blood leukocytes count and neutrophilic granulocyte precentage before and after the treatment had no statistical signifi-cance(P>0. 05). The effective rete of the treatment group was 86. 11%,and that of the control group was 88%(P>0. 05). The pos-itive detection rate of pathogenic bacteria was 75. 41%, in which Escherichia coli was the first pathogenic bacteria. The bacterial clear-ance in the treatment group was 85. 96%, which was higher than that (80%) in the control group(P>0. 05). Conclusion:The effi-cacy of piperacillin/tazobactam in the treatment of children with congenital megacolon enteritis is more obvious with promising safety.

Objective To compare the ultrasonic and mammographic appearances of breast chronic inflammation (BCI). Methods The ultrasonic and mammographic features of 20 pathologically conifrmed BCI cases were analyzed retrospectively. All cases were of single lesion. Fisher deifnite probability method was used to compare the differences between ultrasonic and mammographic appearances as well as the diagnostic coincidence rate. Results Under ultrasonography, the mean longitudinal diameter/transverse diameter (L/T) ratio of 20 lessions was calcultated as 0.47±0.15, 17 lesions were of irregular shape, unclear boundary and inhomogeneous hypoecho, 13 lesions were of posterior echo enhancement, the blood lfow of 10 lesions belonged to 0-Ⅰ, and the other 10 belonged toⅡ-Ⅲ. The lesion shape, boundary and homogeneity detected by mammography were coincident to those by ultrasonography (P=1.00, 1.00, 0.61, respectively). In 5 lesions, dotted high-echoes were detected by ultrasonography, however no calciifcation was found by mammography. Meanwhile, 1 lesion with sporadic calciifcation detected by mammography was missed by ultrasonography. Ultrasonography detected 5 cases with axillary lymphadenopathy, in which only 1 case was found by mammography. The diagnostic coincidence rate of ultrasonography was 40%(8/20), which was obviously higher than 6% (1/16) by mammography (P=0.03). Conclusion BCI possesses certain ultrasonographic characteristics, and ultrasonography combined with mammography will be helpful for the differential diagnosis of malignant and benign diseases.

Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2 years, PAI-1 4G/4G genotype may be a negative predictor for the progression of CCA-IMT in T2DM patients.
