ABSTRACT
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative method for various hematological diseases. With the optimization of transplantation technology, the clinical application of allo-HSCT is more and more mature. Post-transplant liver injury is one of the common postoperative complications, which seriously affects the quality of life and long-term survival of patients. The causes of liver injury after allo-HSCT can be divided into non-infectious and infectious factors, which show similar clinical manifestations and different treatment principles. Timely diagnosis of post-transplant liver injury and the identification of the disease cause will be beneficial for early prevention or targeted treatment, thereby improving patients' prognosis. This review focuses on the etiology, clinical features, and treatment options of liver injury after allo-HSCT, aiming to deepen the understanding of hematologists on liver injury after allo-HSCT.
ABSTRACT
OBJECTIVE: To observe the effect of integrated Chinese and Western medicine for the treatment of occupational noise-induced deafness( ONID). METHODS: A total of 80 ONID patients were selected and randomly divided into control group and treatment group by judgment sampling method,with 40 cases in each group. The control group received routine western medicine treatment using mecobalamin tablets,vitamin B complex,nerve growth factor and hyperbaric oxygen. The treatment group received routine western medicine as the control group,plus acupuncture,moxibustion and auricular point pressing. The patients in both groups were treated continuously for 30 days. The questionnaire of conscious,the selfconscious symptoms such as tinnitus,headache,dizziness and insomnia were recorded in these two groups before and after treatment. Pure tone audiometry was performed on the patients at the same time. RESULTS: After treatment,the binaural high frequency threshold average( BHFTA) and threshold of weighted value of the left and right ears in the treatment group were better than that in the same group before treatment( P < 0. 05). The difference of the BHFTA and threshold of weighted value of the right ear in the treatment group before and after treatment was higher than that in the control group( P < 0. 05). After treatment,the symptoms of tinnitus,headache,dizziness and insomnia in the two groups were better than those in the same group before treatment. The total improvement rate of tinnitus and dizziness symptoms in the treatment group was higher than that in the control group( P < 0. 05). CONCLUSION: The treatment with integrated traditional Chinese and Western medicine for ONID can improve the hearing level of patients,effectively alleviate the accompanying self-conscious symptoms,and is suitable for promotion in clinical use.
ABSTRACT
Objective To study the epidemiological features of Cryptococcus neoformans and Cryptococcus gattii isolated from clinical samples in Shenzhen and to elucidate the distribution of species,varieties,genotypes and mating types within the strains tested.Methods The strains involved in this study were 55 cryptococcal strains isolated from our clinical samples.The canavanine-glycine bromthymolblue (CGB) culture was performed to distinguish Cryptococcus neoformans from Cryptococcus gattii.The genotype was characterized by polymerase chain reaction (PCR) fingerprinting with primer M13.The Cryptococcus gattii species and varieties of grubii and neoformans together with two opposite mating type α and a were identified by PCR with variety-specific and mating type-specific primers.The GEF1-restriction fragment length polymorphism analysis was conducted to simultaneously determine the genotype and mating types of strains tested.The sequence type of IGS1 region was analyzed for the VG Ⅱ genotype.Results Of the 55 tested cryptococcal strains,52 were Cryptococcus neoformans,all of which were var.grubii,genotype VN Ⅰ and mating type α.The remaining 3 strains were Cryptococcus gattii,among which,one was genotype VG Ⅰ and mating type α,and two were genotype VG Ⅱ and mating type α.The two VGⅡ genotype strains belonged to the sequence type Ⅱ.Conclusions The strains belonging to the Cryptococcus neoformans var.grubii,genotype VN Ⅰ and mating type α predominate in causative pathogens of cryptococcosis in Shenzhen.Cryptococcus gattii accounts for minority of the cryptococcal isolates,and the highly pathogenic VG Ⅱ genotypes in foreign countries are also characterized.The sequence types of IGS1 region of the two VG Ⅱ strains are in accord with VG Ⅱb sub-genotype.
