Reactive oxygen species(ROS)and immune response play critical roles in the progression of liver dis-eases.DJ-1,also known as Parkinson disease 7(Park7),is extensively expressed in cells and tissues,where it governs numerous biological functions including chaperone activity,protease function,tran-scriptional and mitochondrial regulation,and ROS modulation.Moreover,we have established that DJ-1 plays a critical role in initiating an inflammatory response by modulating ROS generation.Therefore,DJ-1 may play an important role in the progression of liver diseases by modulating ROS and the immune response.Recently,we have shown that DJ-1 deficiency negatively regulates proliferation of hepatic progenitor cells(HPCs)by impairing the formation of HPC-associated fibrosis and inflammatory niches.Deficiency of DJ-1 ameliorates liver fibrosis by inhibiting hepatic ROS production and inflammation;moreover,in a classic diethylnitrosamine(DEN)-mediated hepatocellular carcinoma(HCC)mouse model,deletion of DJ-1 ameliorates tumorigenesis and HCC cell proliferation by regulating hepatic inflammation and reducing the activity of the interleukin 6/signal transducer and activator of transcription 3(IL-6/STAT3)signaling pathway.Taken together,these data suggest a critical function for,and therapeutic value of,DJ-1 in treatment of liver diseases.The aim of this review is to summarize these functions and the underlying molecular mechanisms of DJ-1 in liver diseases,and to highlight the potential therapeutic value and future research direction of DJ-1 in liver diseases.

Objective To investigate the effect of KIR-HLA receptor-ligand model on the unrelated allo-hematopoietic stem cell transplantation (Allo-HSCT) of acute lymphoblastic leukemia (ALL). Methods The KIR genotype of 23 pairs of ALL patients and their HLA-matched unrelated donors obtained from the Database of China Marrow Donor Program. KIR genotype was determined using PCR-SSP. The expression of inhibitory KIR(iKIR) was determined by flow cytometry analysis on recipients after HSCT. Results Among all 23 donor/recipient pairs, 17 donors with KIR2DL2/L3 could find corresponding HLA-Cw1, 3, 7, 8, 12, 14 ligands in their recipients. Six donors with KIR2DL1 could match with HLA-Cw6, 15 in recipients. Sixteen donors with KIR3DL1 could recognize HLA-Bw4 and 12 donors with 3DL2 could find HLA-AI1 in their corresponding recipients, respectively. Ninteen patients were successfully transplanted, and the death rate of transplantation were 33.3% (2/6)and 40.0% (2/5) in KIR receptor-ligand matched model and the graft versus leukemia(HVG) KIR ligand-mismatching pattern. The frequency of acute graft versus host disease(GVHD) was 50.0% and death rate was 12.5% (1/8) in GVH KIR ligand-mismatching. The incidence rate of activated GVHD(aGVHD) was 20.0% in the HVG KIR ligand-mismatching. Five donor/recipient pairs of KIR gene typing were the KIR-haplotype A, 2 donor/recipient pairs with KIR2DS4 * 001/002 were died, 3 donor/recipient pairs with KIR2DS4 * 003-007 were obtained the disease free survival. The expression of CD158a/2DL1 was low when the patient had no aGVHD, but became much higher when aGVHD occurred. The percentage of NK cell of the patients was decreasing since transplantation, but still higher than normal after HSCT[ (23.4 ± 3.8 ) % vs (2.04 ± 0.58) %, P < 0.05 ]. Conclusion Analysis on KIR-HLA gene loci pattern may provide a useful parameter in predicting the clinical outcome of HLA-matched unrelated allogeneic hematopoietic stem cell transplantation for leukemia patients. Moreover, it may help to increase overall survival and disease free survival after HSCT by preventing the development of GVHD.

Objective To explore the impact of sense of coherence on coping style in patients with AIDS (acquired immune deficiency syndrome). Methods The general data, sense of coherence and coping style of 80 patients with AIDS were evaluated by the sense of coherence scale ( SOC-13 ) and medical coping modes questionnaire. The correlation between sense of coherence and coping style in patients with AIDS was analyzed. Results The average score of sense of coherence was (63. 6 ± 10. 3), the highest score of the 3 dimensions was comprehensibility (5. 0 ± 1. 1), followed by meaningfulness and manageability[ (4. 8 ± 0. 9) vs (4. 7 ± 1. 0)]. The score of confronce, avoidance and resignation in medical coping modes questionnaire was (2. 2 ± 0. 5), (2. 2 ± 0. 3) and (2. 0 ± 0. 6). The score of confronce in patients with AIDS was lower than the norm, and the score of avoidance and resignation were higher than the norm. The differences were statistically significant ( P < 0. 05 ). There was positive correlation between confronce and comprehensibility, meaningfulness, sense of coherence (P<0. 05). The avoidance and manageability showed a negative correlation (P < 0. 01 ). There was negative correlation between resignation and manageability, comprehensibility, meaningfulness, sense of coherence (P<0. 01). Conclusions The senses of coherence in patients with AIDS need to be improved, and nurses should provide personal interventions to make the patients take positive coping styles.

The research on human hepatobiliary development and disorders has been constrained by minimal access to human fetal tissue, and low accuracy of animal models. To overcome this problem, we have established a system for the differentiation of human pluripotent stem cells (hPSCs) into functional hepatobiliary organoids (HBOs). We have previously reported that our 45-d approach closely mimics key stages of hepatobiliary development, starting with the differentiation of hiPSC into endoderm and a small part of mesoderm, and subsequently into hepatoblast-like cells, followed by the parallel generation of hepatocyte-like cells and cholangiocyte-like cells, formation of immature HBO expressing early hepatic and biliary markers, and mature HBO displaying hepatobiliary functionality. In this study, we present an updated version of our previous protocol, which only needs 35 days to achieve maturation in vitro. Furthermore, a hepatobiliary culture medium is developed to functionally maintain the HBOs for more than 1.5 months. The capacity of this approach for producing large amounts of functional HBOs and enabling long-term culture in vitro holds promise for applications on developmental research, disease modeling, as well as screening of therapeutic agents.

Objectives To analyze the distribution and drug resistance of pathogenic bacteria in neonatal department,and to provide criteria for rational clinical use of antibiotics. Methods Totally 15,796 specimens ob-tained from neonates were cultured according to the operation specification. The isolated pure strains were identified and their drug susceptibility was tested by VITEK-2 automated microorganism identification system. Results A to-tal of 1,125 strains of bacteria were isolated and the total detection rate was 7.1%. Of the total,742(66.0%)were gram-negative bacteria ,355(31.6%)gram-positive bacteria and 28(2.4%)fungi. K pneumonia was the most fre-quently isolated pathogen in gram-negative bacteria ,and staphylococcus the most frequently isolated pathogen in gram-positive bacteria. G-bacteria were highly resistant to ampicillin ,1st and 2nd generation cephalosporin. The re-sistant rates of K pneumonia,P aeruginosa and A baumannii to imipenem were>24.0%.Among the staphylococ-cus,35.7%were MRSA and 73.3%MRSCN. The antibiotic sensitivities of staphylococcusto vancomycin,Rina thia-zole alkanes and Tigecycline were 100.0%,but those to penicillin,cephalosporin and erythromycin low. Conclu-sion The dominant bacteria isolated from specimens obtained from neonates are gram-negativebacteria ,and they present extensive antibiotic resistance.

Objective:To explore and analyze the online Q&A texts for hyperglycemia in pregnancy (HIP) users in online health communities, and to provide references for health information services for HIP patients.Methods:A total of 108 590 Q&A texts were collected from "Diabetes Forum" and "Mom Forum". Social network analysis was used to construct the co-occurrence network of feature words in text content and carry out visual analysis and display. On the basis of identifying content themes, the relationship between themes and the nodes within themes were further analyzed, and the attributes of content themes were differentiated with Wilson's information behavior model.Results:In this study, a question and answer text feature word network for pregnant hyperglycemia users with 321 nodes was constructed, among which the largest sub-net included 177 nodes. A total of 12 content themes were identified to seek motivation around two major categories of information, including blood sugar control and coping with disease stress. Among them, the themes with physiological, cognitive, and emotional attributes were 4, 7 and 6, respectively. The number of feature words contained in drug treatment, diet and nutrition was the most prominent, and there were feature words with high degree of centrality in each theme.Conclusions:The content that hyperglycemia in pregnancy (HIP) users pay attention to has multiple attributes and dimensions. Clinical and community healthcare workers and other health information providers can continuously improve the information service content for HIP patients to meet their health information needs.

OBJECTIVETo investigate the role of different immunoglobulin- like receptor (KIR)haplotypes in haplo- identical hematopoietic stem cell transplantation (HSCT).

METHODKiller cell KIR genotyping was performed on 468 individuals from 156 unrelated families by PCR-SSP. A total of 624 KIR haplotypes from the parents were used for haplotype analysis. Ninety-two patients received haplo-identical HSCT from one of the parents.

RESULTSThe family study showed segregation of one A haplotype and at least 20 unique B haplotypes. The frequency of haplotype A was 72.92% (455/624). The most commonly observed haplotypes in group B were B1, B2, and B3, present at a frequency of 10.26%, 5.77%, and 4.48%, respectively. Compared to KIR gene matched donors (n=17), grafts from KIR gene mismatched donors (n= 14) had a positive effect on survival after haplo- identical HSCT for AML/MDS patients (OS: 88.2%vs 42.9%,P=0.015; RFS: 88.2%vs 35.7%,P=0.007). No effect was observed for ALL/NHL patients (OS: 76.0%vs 75.0%,P=0.727; RFS: 68.0%vs 65.0%,P=0.866). A significantly lower survival rate was observed for transplants from AA (n=52) and AB1/AB2 donors (n=15), compared to other group Bx donors (n=25) (OS: 53.3%vs 96.0%,P=0.017; RFS: 53.3%vs 92.0%,P=0.019). Meanwhile, the risk of relapse was much higher in AA group (n=52) compared to Bx group (n=40) (25.0%vs 5.0%,P=0.009). A higher risk of TRM was observed in AB1/AB2 group (P=0.012). In addition, transplant from donors carried Cen-B was associated with an increased survival compared with Cen-A homozygous donors (OS: 94.7%vs 68.5%,P=0.036; RFS: 89.5%vs 64.4%,P=0.045).

CONCLUSIONOverall, KIR genotyping and haplotype analyses should be useful for selection of the most optimal donors with favorable KIR gene grafts. KIR gene mismatch donors should be preferred for AML/MDS patients. Selecting donors carried Cen- B and avoiding the selection of donors of KIR genotype AA/AB1/AB2 was strongly advisable for haplo-identical HSCT.

The traditional experimental teaching mode of forensic science and biological evidence is mostly confined to experimental operation, which is not capable of cultivating students' comprehensive quality and post competency. Therefore, it is urgent to seek an innovative teaching and training mode. At present, the experimental teaching of forensic science and biological evidence is dominated by teachers. There are some problems, such as insufficient training of students' scientific thinking and innovation ability, single teaching and evaluation model, and disconnection from the practical application. This paper proposes an experimental teaching design scheme of forensic science and biological evidence based on post competency training. The course is implanted in the framework of simulated cases, and the virtual simulation experiment platform and group discussion learning method are used to achieve a training model oriented by social needs and centered on students. In the preliminary study on the students who were trained in this mode of selected sections, we found that, compared with traditional teaching, the time for students to complete the prescribed experimental operation in this teaching mode was shortened by 4 minutes on average, and the average score of theoretical course test case analysis questions was increased by 1.5 points. In conclusion, the instructional design of the experiment teaching forensic science and biological evidence can effectively improve students' post-competency, and it deserves further exploration and application.
