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 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.

【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

With Minglou Community Children's Rehabilitation Base as a case,which was jointly founded by tertiary specialized hospital and community health service center,the paper introduced how to use SWOT model to systematically analyze the strengths and weaknesses of the internal environment,opportunities and threats of external condition.Based on the analysis,the solutions,suggestions and policy of children's rehabilitation were proposed,providing reference for decision making to promote the community children's rehabilitation.

Objective To learn about electrolytes imbalance and water intoxication in children treated with high-dose cyclophosphamide(HD-CTX)as well as the renal function and the relative clinical symptoms,and study the mechanisms of hyponatremia.Methods Patients' clinical manifestations during and after HD-CTX therapy were summarized.Serum electrolytes and creatinine(Cr)were detected before and 6 or 8 hours after therapy with HD-CTX,antidiuretic hormone(ADH) in some patients were measured.Results Of 108 therapeutic cases 24 accompanied with vomits and 22 with a decreased urine output,in which 4 developed eyelid or ankle edema.Seven cases had neural-sarcous symptoms and 5 cases had abdominal pain or diarrhea.Serum sodium decreased significantly after HD-CTX[(139.12?3.30) mmol/L vs(134.06?8.23) mmol/L] in whom rechecked after 6 h,(141.77?3.59) mmol/L vs(133.26?6.41) mmol/L in those rechecked after 8 h(Pa0.05].Serum Cr increased 8 h after therapy[(29.95?13.61) ?mol/L vs(43.33 ? 17.25) ?mol/L P

Objective To investigate the influence of benzopyrene on extracellular matrix(ECM) protein deposition of human airway smooth muscle cells(HASMC) and the related pathway mechanism.Methods HASMC were primarily cultured and the 2-6 generations cells were applied in this experiment.The expression amount of ECM gene and protein was detected by real time PCR and Western Blot the phosphorylation level was analyzed by using the Western Blot method.Results Benzopyrene could to increase the expression of HASMC collagen Ⅰ α1 protein (P＜0.01) and ECM protein (including collagen Ⅰ α1,versican,fibronectin,laminin α2) mRNA(P＜0.05).Benzopyrene could induce the rapid increase of ERK1/2 phosphorylation level (P＜0.01).Furthermore,the ERK pathway inhibitor PD98059 could significantly inhibit the increase of benzopyrene-induced collagen Ⅰ α1 (P＜0.01)and ECM protein(including collagen Ⅰ α1,versican,fibronectin,laminin α2) mRNA expression(P＜0.01).Conclusion Benzopyrene induces the ECM protein deposition of HASMC by activating the ERK1/2 pathway,blocking the ERK1/2 signal pathway can inhibit the benzopyrene-induced airway remodeling.
