Steroid-resistant nephrotic syndrome (SRNS) is a relatively difficult clinical type of treatment.The major therapy measures in present include steroid and immunosuppressant.Commonly used immunosuppressant include tacrolimus,cyclosporin,cyclophosphamide,mycophenolate mofetil,ect.Tacrolimus-induced clinical remission rate is superior to other immunosuppressive agents,has been the first-line agent of SRNS.Because of the individual difference in metabolism,the drug concentration of tacrolimus should be determined periodically.In order to obtain optimal efficacy of tacrolimus and reduce renal toxicity,the treatment protocols of small doses with long courses for children with SRNS were recommended.

Background and purpose: MORC2 (microrchidia family CW-type zinc finger 2, MORC2) is a newly identified chromatin remodeling protein that plays key roles in DNA-based biological processes including gene transcription and DNA damage repair. However, its functional role in breast cancer development and progression re-mains unknown. ALDH1A3 (aldehyde dehydrogenase 1 family member A3), a member of the aldehyde dehydrogenases (ALDH) superfamily, is a putative breast cancer stem cell marker, but its regulatory mechanism in breast cancer is poor-ly characterized. This study aimed to investigate the effects of knockdown of endogenous MORC2 on the expression levels of ALDH1A3 and the breast cancer stem-like phenotype in MCF-7 cells. Methods: Human breast cancer MCF-7 cells were infected with negative control short hairpin RNAs (shNC) and specific shRNAs targeting human MORC2 (shMORC2), followed by selection with puromycin to generate stable MORC2 gene knockdown cell lines. Western blot and real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) were used to examine the protein and mRNA levels of ALDH1A3 in MCF-7 cells stably expressing shNC and shMORC2. Microsphere formation and fluo-rescence-activated cell sorting (FACS) assays were used to analyze the effects of knockdown of MORC2 on the breast cancer stem-like phenotype. Results: Western blot and RTFQ-PCR analyses revealed that the protein and mRNA levels of ALDH1A3 were significantly down-regulated in shMORC2 expressing cells as compared with shNC -transfected control cells. Moreover, mammosphere formation assay showed that knockdown of endogenous MORC2 in MCF-7 cells significantly reduced the ability of cells to form microspheres. Consistently, FACS assays demonstrated that shMORC2-transfected cells had a lower proportion of ALDH-positive stem cells as compared with shNC expressing cells. In contrast, knockdown of MORC2 did not significantly affect the CD44+CD24- stem cell population. Conclusion:MORC2 promotes a breast cancer stem-like phenotype through, at least in part, regulating ALDH1A3 expression.

A strain of Prototheca species isolated from a case of meningitis was identified by routine morphologic and biochemical methods as well as amplification of the related genes, in which the 28S large-subunit (LSU) region of ribosomal RNA (rRNA) gene and intergenic space (ITS) were amplified with universal fungal primers. The small-subunit (SSU) rRNA gene was amplified with eukaryote-specific primers and Prototheca genus-specific primers. Then, compared the sequences with the ones posted on BLAST (www. ncbi. nlm. nih. gov/BLAST). The organism choice giving the closest match, up to 99%, was considered the most likely correct identification. It was found that this strain of fungus grew well at 25 ℃ or 37 ℃. Smooth,moist colonies with white color were observed on Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA). Microscopically, globular or ovoid cells, a number of round, ovoid shaped endospores could be observed. No hypha, ascus or blastic conidia was found upon cultivation on SDA. Based on the morphological characteristics, this isolate could be identified as Prototheca species. The identity with Prototheca wickerhamii was 2.9 % as demonstrated by the API 20C AUX system. Sequence analysis showed that the ITS gene was proved to be a complex structural region which was not suitable for the identification of Prototheca species, but the LSU and SSU rDNA regions showed 94% and 99.9% sequence identities with Prototheca zopfii var. hydrocarbonea (P. zopfii var. hydrocarbonea) respectively, indicating that the SSU rRNA gene sequence might be more reliable on than the LSU rRNA gene sequence for identification of Prototheca species.

ObjectiveTo investigate and analyze the health education needs of TCM rehabilitation after hepatobiliary surgery,and the application effect of health education. Methods105 cases of hepatobiliary surgery patients were chosen.Homemade questionnaires with TCM rehabilitation related knowledge needs were used in the investigation.And then the health education of TCM rehabilitation was given to the patients.After these patients accepted the education and were rehabilitated,these patients were again taken TCM and rehabilitation of health education needs for investigation.The changes of the needs of the patients before and after education for the rehabilitation of health education on TCM were compared.The evaluation of the recovery effect for patients with TCM rehabilitation of health education in the liver and gallbladder surgery were taken for investigation. Results105 cases of patients with TCM and rehabilitation health knowledge education before and after the survey results showed that,the urgent need on the knowledge of TCM health rehabilitation rate after hepatobiliary surgery in patients increased significantly compared with before education.In the evaluation of the recovery effect of patients for TCM rehabilitation of health education in theliver and gallbladder surgery,the rate of thinking it effective in promoting postoperative recovery was 91.43％. ConclusionsHepatobiliary surgery patients were lack of knowledge of postoperative recovery of health knowledge of TCM and rehabilitation.By education and practical application,the patients understand the importance of health education on their postoperative rehabilitation,so TCM rehabilitation of health education has an important clinical significance in hepatobiliary surgery patients.
