Background： Tat-interacting protein 30 （TIP30） has been reported to be a tumor suppressor, with reduced or absent expression in various tumors. However, its role in bladder urothelial cancer （BUC） has not been investigated. Therefore, herein, we investigated the expression of T1P30 protein in BUC and normal bladder mucosa and the clinical significance of TIP30 expression in the prognosis of BUC. Methods： We reviewed data from 79 cases of BUC and 15 adjacent tissue samples from 79 patients treated at our institution between 2004 and 2007. TIP30 expression was examined by immunohistochemistry. The relationship between TIP30 expression and tumor stage, histological grade, and survival was analyzed. Differences between groups were evaluated using the t-test or matched-pairs test, and differences in the survival rates were analyzed with the log-rank test. Results： TIP30 protein expression was significantly reduced in BUC tissue （t = -6.91, P 〈 0.05） compared with normal tissue samples, and in invasive bladder cancer （t = 10.89, P 〈 0.05） compared with superficial bladder cancer. TIP30 protein expression differed significantly among different differentiated groups classified either according to the World Health Organization （2004, F = 17.48, P 〈 0.01） or World Health Organization （1973, F = 10.68, P 〈 0.01）. TIP30 protein expression was significantly reduced in high-grade papillary urothelial carcinoma compared with papillary urothelial neoplasm of low malignant potential （P 〈 0.05） and low-grade papillary urothelial carcinoma （P 〈 0.05）. Meanwhile, TIP30 protein expression was significantly reduced in Grade 111 BUC, compared with Grade I （P 〈 0.05） and Grade 11 （P 〈 0.05）. Patients with low T1P30 expression showed a higher incidence of disease progression than those with high TIP30 expression （t - 2.63, P 〈 0.05）. Kaplan-Meier survival analysis showed a strong positive relationship between TIP30 expression and overall survival （OS）（x^2 = 17.29, P 〈 0.05）. Conclusions： TIP30 expression was associated with clinical tum

BACKGROUND X-linked agammaglobulinemia is a primary immunodeficiency disease caused by gene mutations of Bruton’s tyrosine kinase(BTK).We found a new mutation point and summarized the correlation analysis and performed a literature review.CASE SUMMARY The proband was a 5-year-old boy.He was admitted to our hospital due to a recurrent cough and a fever that had persisted for a month.He had a history of multiple respiratory infections and sinusitis.There was no immunodeficiency or recurrent infection history among his family members.Agammaglobulinemia was characterized as follows:Immunoglobulin(Ig)A,90.0 mg/dL(90-450 mg/dL);IgG,20.0 mg/dL(800-1800 mg/dL);and IgM,18.0 mg/dL(60-280 mg/dL).Notably,the assessment of IgG subtypes revealed the following very low levels:Subtype 1,0.26 g/L(3.62-12.28 g/L);subtype 2,0.10 g/L(0.57-2.9 g/L);subtype 3,0.009 g/L(0.129-0.789 g/L);and subtype 4,0.003 g/L(0.013-1.446 g/L).Cellular immunological test results were as follows:CD3,74.6%(50%-84.0%);CD4,47.3%(27.0%-51.0%);and CD8,24.9%(15.0%-44.0%).A de novo hemizygous deletion in BTK was detected:c.902_c.904delAAG/p.E301del.Transcript levels of the mutant BTK were similar to those of the wild-type gene,though overexpression resulted in markedly reduced levels of mutant BTK(9.49%±1.58%),relative to the wildtype BTK(75.8%±2.98%,P<0.01).CONCLUSION This case of X-linked agammaglobulinemia was attributed to a de novo hemizygous deletion mutation in BTK(c.902_c.904delAAG/p.E301del).The mutation resulted in markedly reduced BTK protein stability in vitro.

Objective: To explore the expression of transferrin(Tf) and transferrin receptor(Tf R) in hematoma brain tissue at different stage after intracerebral hemorrhage(ICH) in rats. Methods: ICH rats model were established by collagenase method, and rats were sacrificed at 24 h, 72 h, 7 d and 14 d after operation. The levels of Tf and Tf R in different periods of rats were detected by immunohistochemical method, and correlation between two groups was analyzed. Results: Tf, Tf R-positive cells at each time after operation in observation group were significantly higher than that in control group(P<0.05). Tf, Tf R-positive cells began to increase from 24 h after the operation and reached the peak 72 h-7 d after surgery, but then gradually decreased. Tf was mainly expressed in nucleus and cytoplasm of neurons and glial cells around the hematoma, but Tf R was mainly expressed in nucleus and cytoplasm of neurons and choroid plexus endothelial cells. Correlation analysis showed that the Tf-positive cell was significantly positively correlated with Tf R-positive cell expression(r=0.447, P=0.022). Conclusions: Tf and Tf R were important transporters in brain tissue excessive load iron transport after ICH, and detecting the expression levels of the two indicators can provide a reference for prognosis treatmentin ICH.

AIM: To establish a cell model harboring replicative clinical hepatitis B virus (HBV) isolates and evaluate its application in individualized selection of anti-HBV agents for chronic hepatitis B (CHB) patients. METHODS: The full-length HBV genomic DNA from 8 CHB patients was amplified by polymerase chain reaction (PCR). All the patients were treated with lamivudine for at least seven months and finally became resistant to lamivudine. The amplified HBV DNA fragments were inserted into pHY106 vectors by Sap Ⅰ?digestion. The recombinant plasmids containing 1.1 copies of HBV genome were transiently transfected into Huh7 cell line, and the levels of HBsAg, HBeAg and intercellular HBV replicative intermediates were determined by ELISA and Southern blot analysis, respectively, with or without lamivudine and adefovir treatment. The antiviral treatment with adefovir was administered to the patients and analyzed in parallel. RESULTS: A total of 25 independent HBV isolateswere obtained from the sera of 8 patients, each patient had at least two isolates. One isolate from each individual was selected and subcloned into pHY106 vector, including 5 isolates with YVDD mutation and 3 isolates with YIDD mutation. All recombinant plasmids harboring HBV isolates were transfected into Huh7 cells. The results indicated that HBV genome carried in HBV replicons of clinical HBV isolates could effectively replicate and express in Huh7 cells. Adefovir, but not lamivudine, inhibited HBV replication both in vitro and in vivo, and in vitro inhibition was dose-dependent. CONCLUSION: The novel method described herein enables individualized selection of anti-HBV agents in clinic and is useful in future studies of antiviral therapy for CHB.

Unisexual reproduction is generally relevant to polyploidy, and unisexual vertebrates are often considered an evolutionary “dead end” due to the accumulation of deleterious mutations and absence of genetic diversity. However, some unisexual polyploids have developed strategies to avoid genomic decay, and thus provide ideal models to unveil unexplored evolutionary mechanisms, from the reproductive success to clonal diversity creation. This article reviews the evolutionary mechanisms for overcoming meiotic barrier and generating genetic diversity in unisexual vertebrates, and summarizes recent research advancements in the polyploid Carassius complex. Gynogenetic gibel carp(Carassius gibelio) is a unique amphitriploid that has undergone a recurrent autotriploidy and has overcome the bottleneck of triploid sterility via gynogenesis. Recently, an efficient strategy in which ploidy changes, including from amphitriploid to amphitetraploid, then from amphitetraploid to novel amphitriploid, drive unisexual-sexual-unisexual reproduction transition and clonal diversity has been revealed.Based on this new discovery, multigenomic reconstruction biotechnology has been used to breed a novel strain with superior growth and stronger disease resistance. Moreover, a unique reproduction mode that combines both abilities of ameiotic oogenesis and sperm-egg fusion,termed as ameio-fusiongensis, has been discovered, and it provides an efficient approach to synthesize sterile allopolyploids. In order to avoid ecological risks upon escape and protect the sustainable property rights of the aquaculture seed industry, a controllable fertility biotechnology approach for precise breeding is being developed by integrating sterile allopolyploid synthesis and gene-editing techniques.This review provides novel insights into the origin and evolution of unisexual vertebrates and into the attempts being made to exploit new breeding biotechnologies in aquaculture.

The short-range order and medium-range order of amorphous carbons demonstrated in experiments allow us to rethink whether there exist intrinsic properties hidden by atomic disordering. Here we presented six representative phases of amorphous carbons（0.1–3.4 g/cm3）, namely, disordered graphene network（DGN）, high-density amorphous carbon（HDAC）, amorphous diaphite（a-DG）, amorphous diamond（a-D）, paracrystalline diamond（p-D）, and nano-polycrystalline diamond（NPD）, respectively, classified by their topological features and microstructural characterizations that are comparable with experiments. To achieve a comprehensive physical landscape for amorphous carbons, a phase diagram was plotted in the sp3/sp2versus density plane, in which the counterintuitive discontinuity originates from the inherent difference in topological microstructures, further guiding us to discover a variety of phase transitions among different amorphous carbons. Intriguingly, the power law, log（sp3/sp2） ∝ ρn, hints at intrinsic topology and hidden order in amorphous carbons, providing an insightful perspective to reacquaint atomic disorder in non-crystalline carbons.
