Objective To explore the diagnosis and treatment of Mycobacterium tuberculosis infection in a child with severe β Mediterranean anemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods The clinical data of a child with severe β mediterranean anemia who had Mycobacterium tuberculosis after allo-HSCT were retrospectively analyzed.The pertinent literatures were reviewed.Results Six-year-old girl with Mediterranean anemia was infected by Mycobacterium tuberculosis after allo-HSCT.After anti tuberculosis treatment by HRZE (isoniazid,rifampicin,pyrazinamide and ethambutol),the condition was improved.Conclusion It is rare of Mycobacterium tuberculosis infection after allo-HSCT,which needs timely diagnose and treatment.

【Objective】To observe the effect of electroacupuncture(EA) on sperm count and quality in oligoasthenozoospermic rats.【Methods】Twenty-four male SD rats were given adenine by intragastral administration to establish oligoasthenozoospermic models.After the modeling,the survival rats were randomized into EA group(N=8) and model group(N=8).EA group was treated with EA of Guanyuan(CV4),Shenshu(BL23) and Sanyinjiao(SP6) acupoints.Other 10 rats served as the normal controls.Sperm samples were analyzed by computer-aided semen analysis system(CASA) and the observed sperm parameters included sperm concentration,semen viability and percentage of forward progressive sperm.【Results】Compared with the normal group,sperm concentration,semen viability and percentage of forward progressive sperm were much decreased in the model group(P

0.05).The scales of subtests including arithmetic,digit span,picture completion,block design and coding of children in CAE group were significantly lower than those of control group(Pa

0.05). The absorbance value of Trichinella-infected muscle conserved at -20 ℃ for 10 wk decreased to 0.43, with significant difference from that conserved at -20 ℃ for 1 wk, but the positive rate was also 100%, and antibodies were detected in all muscle samples conserved at -20 ℃ for 20 weeks when the experiment was ended. Conclusion When animals died or were slaughtered and serum samples could not be collected, muscle juice can be collected from fresh, cool and frozen meat and used as a substitute sample for detecting anti-Trichinella antibodies.

Phosphoinositide 3-kinase/serine-threonine kinase (PI3K/AKT)has been found playing an important role in the pathogenesis of severe acute pancreatitis (SAP)in recent years,but the underlying mechanism has not been clarified.Aims:To investigate the role of PI3K/AKT in regulating the inflammatory response in SAP by evaluating the effect of insulin-like growth factor-Ⅰ (IGF-Ⅰ)and wortmannin,the agonist and inhibitor of PI3K/AKT on Toll-like receptor 4 (TLR4)signaling pathway in macrophage cell line RAW264.7.Methods:RAW264.7 cells were treated with different concentrations of lipopolysaccharide (LPS ), IGF-Ⅰ and wortmannin, respectively, and cell viability was determined by CCK-8 assay.RAW264.7 cells were divided into blank control group (no treatment),LPS group (LPS 1 μg/mL),IGF-Ⅰ group (IGF-Ⅰ 100 ng/mL +LPS 1 μg/mL),wortmannin group (wortmannin 100 nmol/L +LPS 1 μg/mL)and IGF-Ⅰ +wortmannin group (wortmannin 100 nmol/L +IGF-Ⅰ 100 ng/mL +LPS 1 μg/mL).Protein expressions of tumor necrosis factor-α(TNF-α)and interleukin-6 (IL-6)were detected by ELISA;mRNA expressions of TLR4,myeloid differentiation factor 88 (MyD88),AKT,PI3K,p38 mitogen-activated protein kinase (p38MAPK)and nuclear factor-κB (NF-κB)were determined by real-time PCR.Results:After treated with LPS,IGF-Ⅰand wortmannin, respectively,no differences in cell viability of RAW264.7 cells were found between different concentrations groups (P>0.05).Protein expressions of TNF-αand IL-6 in LPS,IGF-Ⅰ,wortmannin and IGF-Ⅰ +wortmannin groups were significantly higher than those in blank control group (P<0.05 ).Protein expressions of TNF-αand IL-6 in wortmannin group were significantly lower than those in LPS and IGF-Ⅰ groups (P<0.05),and those in IGF-Ⅰ+wortmannin group were significantly lower than those in IGF-Ⅰ group (P<0.05).In LPS group,mRNA expressions of AKT and PI3K as well as TLR4 and its downstream molecules MyD88,p38MAPK and NF-κB were significantly higher than those in blank control group (P <0.05 ).Expressions of all above-mentioned mRNAs in IGF-Ⅰ group were further increased and significantly higher than those in LPS group (P<0.05).Expressions of all above-mentioned mRNAs in wortmannin group were significantly lower than those in LPS and IGF-Ⅰ groups (P<0.05 ),and those in IGF-Ⅰ+wortmannin group were significantly higher than those in wortmannin group (P<0.05),but significantly lower than those in IGF-Ⅰ group (P<0.05).Conclusions:PI3K/AKT might regulate TLR4 signaling pathway and its downstream molecules in macrophages, thereby affects the expressions of inflammatory cytokines and being involved in the pathogenesis of inflammatory response in SAP.

Graduation project is key link in the cultivation of innovative talents for college teaching work,which is the need of the era.Thus,this paper introduced the current development of biomedical engineering at home and abroad,and the achievement of the graduation project of our university at present.Then,the necessity of the teaching reform and innovation of graduation project are analyzed.The methods for the teaching reform and innovation of graduation project are introduced including the choice of projects,the adjustment of the project schedule,reinforcing the practice of projects and improving the ability to apply knowledge,the assessment criteria of grades for the project,etc.

Objective:To investigate the role of clinical pharmacists in the anti-infective treatment of one patient with complexity urinary tract infection with septic shock induced by cellulitis. Methods:Clinical pharmacists participated in one case of complexity uri-nary tract infection with septic shock induced by cellulitis, and according to the clinical curative effect and the patient' s condition change, clinical pharmacists adjusted the medication nine times and provided individualized pharmaceutical care and service in the whole process. Results:Physician accepted the suggestions of clinical pharmacists, the infection was controlled after the 38-day treat-ment, and then the patient was discharged from the hospital. Conclusion:Clinical pharmacists should participate in the clinical treat-ment, provide whole process of pharmaceutical care for severe patients and assist physician in drug treatment decisions to promote safe, effective and economical drug use.

Objective To optimize the formula of konjac glucomannan-paeonol matrix tablets. Methods The formula of paeonol matrix tablets was optimized by the orthogonal design with the accumulative release rate in vitro as index, with the viscosity of konjac glucomannan ( KGM) , the amount of KGM and lactose as influence factors. Results The optimized formula was as follows:the viscosity of konjac glucomannan was 20 000 mPa·s, KGM 30%, lactose 20% and the release in vitro fit into the Higuchi equation. Conclusion The formula of the paeonol matrix tablets is reasonable and the tablets have well release effect in vitro.
