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.

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.

【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

Objective To establish a method of sperm DNA extraction in mixed stain by using DNase-Ⅰ purificationcombined with alkaline lysis method in forensic science.Methods 79 mixed stain samples of criminal cases were collected.Sperm DNA was extracted using the purification of DNase-Ⅰ binding alkaline lysis method.16 STR loci were genotyped with fluorescent multiplex amplification system.The typing results were compared with that of extracted using two-step differential extraction procedure.Results Of all 79 mixed stain samples,64 samples were genotyped successfully by using DNase-Ⅰ purification combined with alkaline lysis method while 57 samples were genotyped successfully with two-step differential extraction procedure.There was significant difference between two methods(P=0.039).The purification of DNase-Ⅰ binding alkaline lysis method had a higher success rate and lower cost than that of two-step differential extraction procedure.Conclusion Purification of DNase-Ⅰ binding alkaline lysis method can increase the typing success rate of the mixed stain samples.The method is simple,rapid and easy to be automated,and suitable for forensic identification test.

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.

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 analyze the characteristics and regularity of cross allergic reaction between carbopenems and penicillin.METHODS:2 cases about cross allergic reaction between ertapenem and penicillin were reported,716 cases of cross allergic reaction between carbopenems and penicillin in 9 literatures were collected from databases from Jan.1986 to Jan.2010 and analyzed statistically.RESULTS:The incidence of allergic reactions caused by carbopenems in patients with allergic history were higher than that in patients without allergic history.Allergic reaction mostly occurred within 15 min～49 d.Sound therapeutic efficacy can be achieved because of immediate withdrawal of drug and anti-allergy treatment,patients were with good prognosis.CONCLUSION:Great importance should be attached to monitoring of cross allergic reaction between carbopenems and penicillin and rational use of drugs.

4-fold elevation in renal cortex in plasma aldosterone as compared to those of the SHAM rats. The above pathologies were markedly improved in bi-ectomised rats with significantly lower aldosterone level. Being constantly infused exogenous aldosterone, bi-ectomized rats manifested greater proteinuria, hypertension, glomerulosclerosis and increased level of TGF-?1 compared to bi-ectomised rats. Indeed, these features were similar in exogenous aldosterone rats and 5/6 nephrectomized rats. Furthermore, the expression of mineralocorticoid receptor (MR) mRNA was remarkablely enhanced in SNX group and was decreased in ADX group. However, the mRNA expression of 11 ?-hydroxysteroid dehydrogenase II (11?-HSD2) in each group was opposite to that of MRmRNA. Ccr and kidney/body weight showed no differences among four experimental groups. Conclusion Aldosterone contributes to the progression of ablative nephropathy in the rat through mechanisms other than systolic blood pressure.
