Objective To report a case of cutaneous infection due to Trichosporon dermatis. Methods Lesional discharge and tissue were obtained and subjected to microscopic examination, fungal culture and histopathology, respectively. The fungal isolate was then identified with DNA sequence analysis, API 20C AUX system, gelatin liquefaction test, thermal tolerance test. Antifungal susceptibility test was also performed for the fungus. Results A 70-year-old male presented with a 9-month history of ulcerated swelling of the right medial malleolus after plant puncture. Direct microscopic examination of lesional discharge showed no fungal elements, but histopathological biopsy revealed hyphae and spores in the dermis. Yellowish white yeast-like colony grew on Sabouraud dextrose agar (SDA). Slide culture showed pseudohyphae, true hyphae, arthroconidia and blastoconidia. The isolate was identified as Candida humicola by API 20C AUX system, but as T. dermatis by DNA sequence analysis. The strain was unable to liquefy gelatin, could grow at 25 ℃ to 40 ℃, and was sensitive to amphotericin B, itraconazole, voriconazole and nystatin. The skin lesion completely subsided after 4-month treatment with oral itraconazole. Conclusions The isolate is identified as T. dermatis according to morphological features and DNA sequence, which is sensitive to itraconazole.

OBJECTIVETo explore the relationship between salivary proteome and dental caries and to promote the biomarker studies of dental caries susceptibility by comparing the salivary proteome of caries-active children and caries-free children with electrospray ionization ion-trap tandem mass spectrometry (ESI-MS/MS).

METHODSTen caries-active children and ten caries-free children were sampled. The salivary proteome of the two groups was studied, and the differential protein between the two groups was analyzed by ESI-MS/MS after sodium dodecyl sulfate polyacrylamide gel electrophoresis, filter-aided sample preparation, and liquid chromatography.

RESULTSThe concentration of salivary protein was higher in the caries-active group than in the caries-free group. The polypeptide counts of thecaries-active and caries-free groups were 602 and 481, which belonged to 286 and 227 proteins, respectively. The differential polypeptide count of the two groups was 361, and the differential protein count was 118. The detected proteins included matrix metalloproteinase-9 (MMP9), mucin-7 (MUC7), lactotransferrin (LTF), carbonic anhydrase 6 (CA6), azurocidin (AZU), and cold agglutinin.

CONCLUSIONThe total salivary protein was higher in the caries-active group than in the caries-free group. The preliminary detection of differential proteins (MMP9, MUC7, LTF, CA6, AZU, and cold agglutinin) may lay some foundation for biomarker research of dental caries susceptibility.

The magnetic molecularly imprinted polymers (MMIPs), based on the surface of magnetic nanoparticles being modified by surface grafting, have been successfully synthesized, with dibutyl phthalate (DBP) as template molecule, ethylene glycol dimethacrylate (EGDMA) as cross-linking agent and azobisisobutyronitrile (AIBN) as initiator. Scanning electron microscopy (SEM), transmission electron microscope (TEM), and elemental analysis were employed to characterize the MMIPs. The structure and magnetic properties of the MMIPs were investigated by means of X-ray diffraction and vibrating sample magnetometer. The BET surface area shows that MMIPs is 380 m2/g and MNIPs is 324 m2/g. A series of static adsorption experiments were conducted to analyze its adsorption performance, which followed pseudo-second-order model by the kinetic analysis with correlation coefficient (R2) 0.9797, and Sips equation with correlation coefficient (R2) 0.999 by the isothermal analysis. The imprinting factors of diallyl phthalate (DAP), DBP and di-2-ethylhexyl phthalate (DEHP) were 1.53, 2.21 and 1.39 respectively, showing that MMIPs had better recognition performance for DBP. The experiment of regeneration recycles with five times showed the regeneration ability of DBP was only reduced by 12.3％.

Objective To retrospectively analyze the outcomes and adverse effects of sequential therapy of BTD and MPT regimen for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation. Methods Thirty-six patients were involved in this study and the patients were treated with tandem therapy of BTD and MPT regimen. The patients were treated with BTD regimen as induced therapy no less than 2 cycles. When the patients got PR or above PR,they were treated with MPT regimen as consolidation therapy which was no less than 2 cycles. Then,the patients who achieved PR or partial PR were received MPT chemotherapy regimen as consequent treatment. After that,low dose thalidomide was used as maintenance therapy. The outcomes and adverse effects were retrospectively evaluated. Results Thirty-six patients were treated with BTD regimen as induced therapy. The results were that 7 patients (19.4 %) achieved CR,8 (22.2 %) VGPR,14 (38.9 %) PR and the OR rate was 80.6 %. The patients (n=29) who achieved no less than PR was treated with MPT regimen as consequent therapy. The results were that four patients were in progression and the others were stable. Twenty-five patients were treated with low dose thalidomide as maintenance therapy. The median progression-free survival (PFS) did not reached yet until last follow-up (median follow-up time was 16.5 months). One-year overall survival rate was expected 86.0 % and 3-year expected overall survival rate was 77.0 %. The main regimen-associated toxicities included thrombocytopenia,peripheral neuropathy (PN),Herpes Zoster,gastrointestinal symptoms,anemia,neutropenia,constipation,fatigue,rash and so on. The incidence of grade 3 and 4 adverse events was low. Conclusion Sequential therapy of BTD and MPT regimen can be used as the front-line therapy for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation.

Objective To evaluate the efficacy and safety of lenalidomide(Len)-based regimens in the treatment to patients with multiple myeloma (MM). Methods Twenty-five multiple myeloma patients who received Len-based regimens were enrolled in this study. There were 5 newly-diagnosed MM patients, 13 relapsed/refractory (rel/ref) MM and 7 MM patients at plateau after treatment. The newly-diagnosed patients received R-PAD regimen, rel/ref MM received R-MD and the patients at plateau(maintenance treatment group) due to more than 2 grade peripheral neuropathy (PN) received Len monotherapy. Results All of the five newly-diagnosed MM achieved complete remission (CR) (100 %) after 2 courses of theatment; of 13 rel/ref patients (76.92 %) achieved overall response, including 3 (23.08 %) achieving CR, 2 (15.38 %) very good partial response (VGPR), 5 (38.46 %) partial response (PR) and the overall response rate was 76.92 %. Two of the other three no response patients had stable disease(SD) and one had progress disease(PO). The seven patients in maintenant treatment group maintained remission in an average follow-up period of 38 weeks and their PN was relieved in various degrees. Conclusion R-PAD regimen is a highly active regimen for newlydiagnosed MM and R-MD regimen is a promising regimen for rel/ref MM, especially for the patients with serious PN; Len may be a good choice as maintenant chemotherapy for the patients with PN.
