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.

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.

Objective To investigate the effects of electroacupuncture at Neiguan point (PC6) and Jianshi point (PC5) combined with granisetron on chemotherapy-induced nausea and vomiting. Methods Seventy-two tumor patients undergoing chemotherapy were randomly divided into an electroacupuncture group (38 patients) and a false electroacupuncture group (34 patients). The electroacupuncture group received electroacupuncture at PC6 and PC5 (1 h, bid) combined with granisetron (3 mg, i.v.) 30 min before chemotherapy, and repeat one time after 12 h. The false electroacupuncture group received electroacupunctur at false PC6 and false PC5, and other treatment same as the electroacupuncture group. Both groups were treated for 3 days. The nausea and vomiting frequencies and clinical effects were compared between the two groups. Results The vomiting frequency in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (0.37 ± 0.75 vs. 1.12 ± 2.13;t=2.034, P=0.046). The nausea degree in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (1.21 ± 0.93 vs. 1.88 ± 0.59;t=3.596, P=0.001) and day 3 (1.26 ± 0.92 vs. 1.68 ± 0.53; t=2.293, P=0.025). The total effective rate in the electroacupuncture group was significantly higher than those in the false electroacupuncture group on day 2 (76.3% vs. 64.7%; χ2=12.390, P=0.006) and day 3 (73.7%vs. 64.7%;χ2=12.313, P=0.006). Conclusions Electroacupuncture at PC6 and PC5 combined with granisetron can attenuate chemotherapy-induced nausea and vomiting.

Objective To study the biological effects of hirudin on the cell circle of fibroblasts in hypertrophic scar.Methods Fibroblasts were taken from normal skin and hypertrophic scar,and cultured in vitro with various concentrations of hirudin.Then,flow cytometry was used for observing cellcycles,and Western blot for some proteins (p27 and cyclin E) related with cell circle.Results With the increasing of the concentrations of hirudin,fibroblasts on G1 phase increased and on S phase decreased,and the expression of protein p27 increased,but that of protein cyclin E decreased.Conclusion Hirudin can influence the cell circle of fibroblasts derived from normal skin and hypertrophic scar by means of the expression of some proteins related with celI circle.Hirudin causes G1 phase arrest and inhibits the production of fibroblasts.Therefore,it seems that hypertrophic scar could be prevented and treated with hirudin.

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.

Objective:To explore the behavior and eye movement characteristics when processing different emotional faces in college students with different levels of social anxiety.Methods:According to the scores of Liebowitz social anxiety scale, 26 and 27 subjects with high and low social anxiety were selected.The response time and accuracy of the subjects under consistent and inconsistent conditions were measured by the dot probe task.Eye movement data of the subjects were recorded when they viewed angry, disgusting and neutral faces.SPSS 19.0 software was used for repeated measurement analysis of variance.Results:The accuracy rates of the high social anxiety group were (0.97±0.10) and (0.93±0.15) under consistent and inconsistent conditions, and the response time of the high social anxiety group were (660.97±125.38) ms and (687.81±150.90) ms under consistent and inconsistent conditions.High social anxiety subjects showed significant differences in the accuracy and response time under different consistency conditions ( F(1, 51)=15.25, P<0.01 for accuracy, F(1, 51)=7.85, P<0.01 for reaction time), while low social anxiety subjects showed no significant difference(both P>0.05). There were significant differences between the first fixation latency for emotional faces and neutral faces( F(2, 102)=15.01, P<0.01). The total fixation time of emotional face and neutral face was significantly different ( F(2, 102)=4.38, P<0.05). Conclusion:College students with different levels of social anxiety all showed early attentional alertness and attentional disengagement difficulty to emotional faces, but only those with high social anxiety showed attentional bias to emotional faces at the behavioral level.
