Our understanding of the immunological mechanisms of rejection has greatly improved over the past 10 years. The allografts have maintained long survival without immunosuppressive treatment in the several organ-transplant recipients combined with hematopoietic stem cell transplantation. The authors attributed the successful outcome to the cotransplantation of donor stem cells. The review will analyze firstly conditions of the recipients, and then review the theoretical basis and history regarding donor-specific tolerance of allograft, and it will also clarify that there is no direct link between the donor-specific transplantation tolerance and hematopoietic stem cell transplantation.

Four methods were compared to purify Fo from porcine h ear t mitochondria. The best results were obtained by the following method: after re moving F1-ATPase with NaBr incubation from submitochondrial FoF1-ATPase, Fo was solubilized with CHAPS and purified by sucrose density gradient centri fugation. SDS-PAGE with silver staining showed about 85% purity of the isolated Fo and 9 different subunits including b, OSCP, d, a, e, F6, IF1, A6L and c. The purified Fo was then incorporated into asolectin liposomes, the reconst ituted Fo showed higher H+ translocation activity and after Fo was reconst ituted with F1-ATPase, the resulted FoF1-ATPase complex exhibited high A TP hydrolysis activity and high sensitivity to oligomycin. The results provide e vidence for successful purification, reconstitution of Fo with high H+ trans location activity and its relationship with phospholipids.

Objective To explore the distribution of ABO blood group in Tibetans population and their genetic relationship. Methods Data of ABO blood group of 28 Titetan populations were collected from China and India. The gene frequencies were processed by Phylip3. 68 and MEGA4. 1 genetic analysis software pack, and the Nei's genetic distance was imported and the genetic relationship was analyzed. Results The distribution of ABO blood group among Gansu, Qianghai, Sichuan, Yunnan, Tibet, and India was 0 ＞ A ＞ B ＞ AB. The nation index and genetic distance were 0. 63 ～ 0.98 and 0 ～0. 0072, respectively. Conclusion There is probable historical relationship among the ancestors of these Tibetan populations, but the differentiation incident of Tibetan population living in different area in history was different, so that their distribution of gene frequencies is diversified.

Objective To research the value of using constant circling individual training program to improve surgery clinical skills of clinical medical specialty interns.Method 42 interns were divided into 3 groups:A(excellent),B(medium) and C(poor) according to their scores in entrance clinical skill test and each group would perform respective training program including conventional training,unified intensive training and intensive training in person.Their performance would be scored six times during the whole process of training.Results Compared with the final scores with beginning scores,the number of students scored A increased significantly meanwhile the number of students scored C decreased obviously.Conclusion The constant circling individual training program combined with effective unified test can benefit improving the surgery clinical skills of the interns of clinical medicine.

Objective: Schizophrenia (SCZ) is one of the most common and severe mental disorders. Modified electroconvulsive therapy (MECT) is the most effective therapy for all kinds of SCZ, and the underlying molecular mechanism remains unclear. This study is aim to detect the molecule mechanism by constructing the transcriptome dataset from SCZ patients treated with MECT and health controls (HCs). Methods: Transcriptome sequencing was performed on blood samples of 8 SCZ (BECT: before MECT; AECT: after MECT) and 8 HCs, weighted gene co-expression network analysis (WGCNA) was used to cluster the different expression genes, enrichment and protein-protein interaction (PPI) enrichment analysis were used to detect the related pathways. Results: Three gene modules (black, blue and turquoise) were significantly associated with MECT, enrichment analysis found that the long-term potentiation pathway was associated with MECT. PPI enrichment p-value of black, blue, turquoise module are 0.00127, <1×10-16 and 1.09×10-13, respectively. At the same time, EP300 is a key node in the PPI for genes in black module, which got from the transcriptome sequencing data. Conclusion It is suggested that the long-term potentiation pathways were associated with biological mechanism of MECT.

This paper reports a case of neonatal lupus syndrome manifested by metabolic disease. A male neonate was admitted to the Children's Hospital of Soochow University due to poor response and vomiting for 1 day. Based on the clinical symptoms, including the patterned skin and a full anterior fontanelle, and a result of leukocytosis, neonatal sepsis was considered. Lysinuric protein intolerance was not excluded from the genetic metabolic disorders screening. The patient was positive for lupus-related autoantibodies and antinuclear antibodies, which were also found in his mother and elder sister. He had no functional variant of the SCL7A7 gene, a gene related to lysinuric protein intolerance, thereby the diagnosis of neonatal lupus syndrome manifested by metabolic disorders was confirmed. After treatment with methylprednisolone, the patient recovered well with no specific change in blood genetic metabolism at re-examination. Monthly follow-up after discharge found decreased antibody titers.
