ObjectiveTo explore the feasibility and safety of the spleen-preserving surgery in the treatment of traumatic rupture.Methods47 patients with traumatic rupture were treated with spleen-preserving surgery:the biological glue which local physical bleeding had 7 cases,suture repair had 13 cases,splenic artery ligation had 10 cases,splenic artery ligation and splenic repair had 9 cases,partial splenectomy had 8 cases.Results47 patients had four cases of infection,and cured after dressing,1 case had postoperative bleeding symptoms and used splenectomy surgery.46 patients with spleen-preserving operation is successful,the average length of stay was 15 days,there is no deaths.After 6 months,all patients used abdominal B-utrasoundor CT scans to confirm the survival of spleen is good and indicator of the examination is normal.Follow-up of these patients had no dangerous infections and complications.ConclusionSpleen-preserving surgery in the treatment of traumatic rupture was safe,feasible,could retain the greatest degree of function,and could be used in clinical practice.

Besides 36 (28 single-tablets and 8 fixed-dose combinations) used antiretroviral drugs clinically, there are a number of investigational antiretroviral agents currently in phase 2-3 clinical trial. Tenofoviralafenamidefumarate (TAF) is a novel nucleoside analogue reverse transcriptase inhibitor that is potent and less toxicity than tenofovir (TDF). Doravirine is a non-nucleoside analogue reverse transcriptase inhibitor that demonstrates activity against NNRTI-resistant viral strains. GSK744 is an integrase inhibitor with a long acting preparation. In addition, several drugs with new mechanisms are also noted, for example, BMS-663 068 is a small molecule CD4 attachment inhibitors and cenicriviroc is a novel CCR5/CCR2 antagonist with antiretroviral activity and anti-inflammatory effects. Several drug classes that target known pathways in HIV latency have being developed, and leading the list are histone deacetylase inhibitors. Other agents include protein kinase C activators, positive transcription elongation factor activators, DNA methyl-transferase inhibitors and histone methyl-transferase inhibitors and so on. This review is focused on the above-mentioned drug candidates that may be used in clinical in next couple of years and those compounds that can reverse latent HIV infections.

In the last decade, next-generation sequencing (NGS) technology, which is characterized by being high-throughput, rapid, sensitive, and accurate, has developed rapidly. Main components of NGS are platforms: 454 sequencing; illumina sequencing; ion torrent sequencing; SOLID sequencing. NGS is used widely for the human immunodeficiency virus (HIV)-1. In this review, we focus on applications of the dynamics of HIV-1 quasispecies.

The Auditory Apperception Measurement Model (AAMM) is often used to test the ability of people's auditory learning. Through learning auditory signals,the testees' apperception abilities are tested under different process of learning. In this paper,the AAMM is built,and the design and realization of the software is introduced.

The educational equity includes the educational rights equity and opportunity equality. Nowadays, real non-equality phenomena exist in our country including in the field of higher education because of many influential factors that affect the educational equity. In the article the author makes the philosophical thinking about the equity and efficiency in higher education through the analysis of these non-equality phenomena, and puts forward that we must hold the principle that efficiency is first, and equity should be stressed at the same time under the condition of insufficient education resource. Meanwhile the educational equity should be enhanced according to the system arrangement and policy adjustment.

The expression of c-met stimulated by high glucose in human renal tubular epithelial cells and the role of HGF/c-met system in diabetic nephropathy were examined. The proximal tubular epithelial cells were cultured in vitro under different conditions. MTT was used for the detection of cellular proliferation and RT-PCR was employed for measurement of c-met mRNA level. Our results showed that under different conditions, there were no significant differences in the proliferation of proximal tubular epithelial cells 12 h and 24 h after the culuture (P>0.05). The proliferation of proximal tubular epithelial cells showed a significant change 96 h after the culture and the cellular proliferation induced by hepatocyte growth factor (HGF) was very active (P<0.05). Moreover, no significant difference in the expression of c-met mRNA was found 12 h after the culture under different conditions (P>0.05), while 24 and 96 h after the culture, a persistent and significantly higher expression of c-met mRNA was found in HGF-induced proliferation. It is concluded that addition of exogenous HGF could inhibit the apoptosis induced by high-level glucose, promote the proliferation of proximal tubular epithelial cells, and induce the expression of c-met. Our study suggests that local up-regulation of HGF/c-met system plays an important role in the repair of renal damage in diabetic nephropathy.
