Objective To summarize the clinical characteristics,diagnosis and treatment of chronic mucocutaneous candidiasis(CMC).Methods The case diagnosed as CMC in the Department of Nephrology and Immunology of Shenzhen Children's Hospital in February 24,2014 was analyzed in terms of symptoms,signs,laboratory findings,gene tests and treatment process,and related literature was reviewed.Results The patient was a 14-year-old boy.The patient started to develop recurrent oral candida infection shortly after birth,then candida infection of skins and nails,which could be alleviated by antifungal agents,but easily relapsed.Since 4 years ago,autoimmune reactions such as autoimmune anemia,thrombocytopenia,leucopenia,proteinuria,and hypothyroidism had successively appeared,and cytopenia began to palliate after administering Glucocorticoid and Cyclosporin,but easily relapsed when the dosage was reduced.The genetic test showed the case was of signal transducer and activator of transcription 1 (STAT1) gain-of-function mutation.During the hospitalization,hemophagocytic syndrome (HPS) and stagnation of hematopoietic function successively occurred.The cytopenia did not improve and the patient suffered severe infection in spite of washing red blood cells 13 times and blood palate 3 times via infusion,together with high dosage of Dexamethasone and Cyclosporine.The peripheral blood cells and bone marrow gradually returned to normal after being treated by human granulocyte colony-stimulating factor combined with Dexamethasone and Cyclosporin.Retrieving the database in PubMed database,824 articles were found which were about CMC,and 39 of them were about the STAT1 gain-of-function mutation,including 120 cases.But there was only 1 domestic case in 2012,who was a three-year-old child,manifesting recurrent fungal infection of the skin.Conclusions STAT1 gain-of-function acquired mutation is one of the reasons that can lead to CMC.Autoimmune reactions prominently represented by cytopenia occur in a few patients with CMC.It should be alert on those who are with CMC and simultaneously with autoimmtne reaction of blood system.And gene tests facilitate the early diagnosis.

Objective To isolate bacteriophages against extensively-drug resistant Acinetobacter baumannii from hospital sewage and analyze their biological characteristics.Methods Extensively-drug resistant Acinetobacter baumannii isolated from several hospitals in Shanghai during December, 2013 to July, 2014 were used as host bacteria, adopting double-layer agar method to isolate bacteriophages from raw sewage of these hospitals.The phage with broad host range was selected for further study, including observation of electron microscopic morphology, examination of thermal stability, pH stability and the optimal MOI, drawing of the adsorption, one-step-growth and infection curves, as well as sequencing of the phage genome DNA. Results An extensively-drug resistant Acinetobacter baumannii bacteriophage vB_AbaP_PD-AB9 ( PD-AB9 for short) with broad host range was isolated, and electron microscopy revealed it belonged to Podoviridae family.The optimal MOI of PD-AB9 was 0.001.PD-AB9 remained stable among 4 ℃to 50 ℃and pH 4 to 11.In the adsorption experiment, the adsorption rate of PD-AB9 reached above 95%within 5 min.PD-AB9 had a latent period of 4 min and a burst size of 213.PD-AB9 could obviously restrain the host growth, with faster effect at the higher MOIs (MOI=1, 0.1, 0.01) than at the lower ones (MOI=0.001, 0.000 1).Furthermore, genome of PD-AB9 proved to be a double-stranded linear DNA with size of 40 938 bp and GC content of 39.34%.Conclusions PD-AB9 exhibits good thermal stability, wide pH tolerance range, very fast adsorption, a short latent period, a large burst size and it could quickly cause effective host lysis after infection.Therefore, PD-AB9 is promised to act as a new antimicrobial agent to control drug-resistant Acinetobacter baumannii infections and its bio information remains to be further studied.

Regulated necrosis is a newly discovered new cell death pathway, including necroptosis, pyroptosis and ferroptosis. It has been reported to play a key role in acute kidney injury (AKI) induced by ischemia/reperfusion, cisplatin and other drugs, and rhabdomyolysis. Studying the role of regulated necrosis-related pathways in AKI is expected to provide a new direction for clarifying the pathogenesis and treatment of AKI, with potential therapy and application prospects. In this review, we summarize the related signaling pathways of necroptosis, pyroptosis and ferroptosis, and the related research progress in AKI, in order to provide potential targets for the prevention and treatment of AKI.

In order to express and purify the catalytic domain of SHP-1/SHP-2 (named as D1C and D2C respectively) and determine their kinetics, the constructed D1C and D2C plasmids were transformed into Escherichia coli BL21 and the expression was induced with IPTG. The harvested cells were suspended in extraction buffer. After sonication, the solution was applied to HPLC and the results were confirmed by SDS-PAGE. The purified peptides were further subjected to kinetic specificity study using synthetic phosphotyrosine (pY) as substrate by malachite green method and analyzed by Lineweaver-Burk plot calculation. From this study, we found D1C and D2C were expressed successfully in soluble state in Escherichia coli BL21 and purified efficiently with HPLC system. The molecular weight of D1C was 34.6 kD, and its Michaelis constant (K(m)) was 2.04 mmol catalytic constant (K(cat)) was 44.98 s(-1), specific constant (K(cat)/K(m)) was 22.05 L/(mmol x s); the molecular weigh of D2C was 35.3 kD, and its Michaelis constant (K(m)) was 2.47 mmol, catalytic constant (K(cat)) was 27.45 s(-1), specific constant (K(cat)/K(m)) was L/(mmol x s). The enzyme activity of D1C is stronger than that of D2C.

Objective To explore the relationships between advanced puberty timing and frequencies of problem behaviors using two different indexes of pubertal development as cut-off standards. Methods A total of 3003 primary school girls aged 6~11 in Beijing were recruited in the study. Parent-assessed Tanner staging according to the menarche and pubic hair development level and the Achenbach Child Behavior Checklist were applied. Results When timing of menarche and pubic hair development stage were used as reference, the detection rate of girls with advanced puberty timing was 11.2% (337/3003) and 3.4% (101/3003), respectively. The scores of withdrawal problem (Z=-2.23, P=0.03) and physical problem (Z=-2.64, P=0.01) were higher in the advanced menarche group than in the moderate group. The scores of withdrawal behavior problem were higher in the advanced pubic hair development group than in the moderate group (X2=2.53, P=0.03). Scores of social problem (X2=2.71, P=0.02), aggression problem (X2=2.50, P=0.04), total score of problem behavior (X2=2.64, P=0.03) were also higher in the advanced pubic hair development group than in the delayed group. The correlation between the pubertal timing results based on the two different cut-off standards was not significant (r=0.04, P=0.06). Conclusion T he detection rate of girls with advanced puberty timing are different using the two different cut-off standards. The prominent problem behaviors in the advanced group are also different. Compared with girls with advanced menarche, girls with advanced pubic hair development may have more prominent problem behaviors than those with moderate development.
