J6-1 cell line is the first leukemic cell line established in China. It is a multi-clone cell line infected with both EBV and HHV-6. Many cytokines, receptors and other genes were cloned from J6-1 cell line since its establishment 30 years ago. Valuable information on leukemic characteristics and functions were obtained from the studies on this cell line, which could be categorized into several research subjects. These achievements implied the unique research value of multi-clone cell lines. This comment focuses attention on research advance of the J6-1 leukemic cell line in 30 years, including heterogeneity and multi-cloning of J6-1 cells, survival mechanism of J6-1 cell populations, abnormal intercellalar communication of J6-1 cells with its significance and inspiration from J6-1 cell line.

Objective To evaluate the value of color Doppler flow imaging (CDFI) in the diagnosis of elderly femoral arterial pseudo aneurysm and treating with ultrasound-guided compression after percutaneous transluminal coronary angioplasty (PTCA). Methods Twenty-six elderly patients who were found a mass and/or vascular murmur in the puncture region were examined by CDFI, and the results of CDFI were proven by clinic and MRI. All pseudo aneurysms were repaired by CDFI guidance to compress simply and/or injecting directly batroxobin into the pseudo aneurysm lumen combined with compression.Results Pseudo aneurysms were diagnosed definitely by CDFI in 26 cases,and the accuracy rate was 100%. Twenty-two cases were repaired with CDFI guidance to compress simply and percutaneously injection of batroxobin into the pseudo aneurysm lumen combined with compression occurred in 3 cases. One case was cured by surgery after failing to be repaired with CDFI guidance. Conclusions CDFI has an important diagnosis value of pseudo aneurysm after PTCA. The method of CDFI guidance compression and batroxobin injection for repairing pseudo aneurysm is simple, safe and effective.

Nature is abundant in protein scaffolds.By selecting suitable protein scaffold,display and screening methods,the rational and constrained random peptide library(RPL)can be constructed.Compared with the non-constrained RPL,it offered more opportunities for obtaining novel protein structures and more higher affinity ligands against the target molecules.At present,the protein scaffold constrained RPLs have been shown great potential in applications such as target selection,basic research,clinical diagnosis,medical therapy and so on.It is systematically introduced the structure bases,classification and construction of constrained RPL based on scaffolds,as well the recent great advances of application in selection against target molecules with S-S constrained scaffolds,antibodies,Zinc finger protein,Z domain,FN3 domain as important examples.

This paper aimed to study the effect nitrogen supplying on biomass accumulation and root respiration dynamic change of Glycyrrhiza uralensis and reveal the metabolic pathway of root respiration impact the biomass accumulating of G. uralensis. Six groups of one-year-old G. uralensis were fertilized with total nutrition containing various nitrogen concentration (0, 0.5, 1, 2, 4, 8 mmol x L(-1)) every week. At the end of every month, from June to October, the volume respiration rate and biomass of different classes of root samples were determined, and the correlation between root respiration and biomass was analyzed. The results indicated a negative correlation between volume respiration rate and biomass, nitrogen supply significantly affected both root respiration and biomass of G. uralensis by reducing root respiration and increasing root biomass. Under 8 mmol x L(-1) nitrogen supplying, there existed the optimal inhibition of root respiration, which has increased biomass of G. uralensis.

Up to date, eight types of human herpes viruses have been identified, all of which are ubiquitous, and usually establish latent infection in the host after primary infection. Since most of the herpes viruses are maintained in an asymptomatic form, they are often neglected. However, under some circumstances, these herpes viruses can cause fatal or severe diseases. Furthermore, the association of herpes viruses with hematopoietic malignancies is attracting researchers' attention. With the extensive development of hematopoietic stem cell and organ transplantation, reports regarding transplantation failure and complication caused by infection of human herpes virus has been increasing. Cytokine storm was firstly suggested as the mechanism of graft-versus-host diseases. In recent years, which has also been applied in the pathogenesis research of inflammation, and is supposed to play an important role in severe virus infection. In this paper, through discussing the possible role of latent infection of human herpes virus in the failure or complication of bone marrow or hematopoietic stem cell transplantation, and in refractory leukemia, the function and significance of latent infection of human herpes virus and the cytokine storm it caused were investigated.

The prescriptions containing pericarpium citri reticulatae that built by Professor. Yan were collected to build a database based on traditional Chinese medicine (TCM) inheritance assist system. After analyzed by data mining, such as apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations can be get from the database. Through the analysis of 1 027 prescriptions with pericarpium citri reticulatae, these prescriptions were commonly used to treat stomach aches, cough and other syndromes. The most frequency drug combinations were "Citri Reticulatae Pericarpium-Poria", "Paeoniae Radix Rubra-Citri Reticulatae Pericarpium" and so on. The drug association rules that the confidence was 1 were "Glycyrrhizae Radix ex Rhizoma --> Citri Reticulatae Pericarpium", "Paeoniae Alba Radix-Cyperi Rhizoma --> Citri Reticulatae Pericarpium", "Poria --> Citri Reticulatae Pericarpium", and so on. The drugs in the prescriptions containing pericarpium citri reticulatae that built by Professor Yan mostly had the effects of regulating the flow of Qi and invigorate blood circulation, which reflected the clearly thought when making prescriptions.

OBJECTIVETo investigate the applications of percutaneous screw fixation for the treatment of pelvic fractures and its related surgical considerations.
METHODSFrom June 2010 to June 2012,19 patients with pelvic fractures were treated with percutaneous hollow screws. There were 13 males and 6 females, with an average age of 41 years (ranged from 22 to 58 years). Fractures were caused by traffic accidents in 11 cases, by falling down from high place in 8 cases. Based on the Tile classification, there were 15 cases of Tile C type and 4 case of Tile B type. The indexes such as screw inserting time, intraoperative blood loss, complications, functional recovery and reduction conditions were observed. Fixation methods included sacroiliac screws, cannulated screw fixation of the pubic ramus and cannulated screw fixation of the pubic symphysis separation.
RESULTSAnatomical reduction achieved in 7 cases, satisfactory reduction 11 cases, and unsatisfactory reduction 1 case. Union time of fracture union ranged from 8 to 12 weeks (mean 10 weeks). Wound infection,ununion of fracture and nerve injuries were not found. According to the Majeed standards, 12 patients obtained an excellent results, 6 good and 1 fair.
CONCLUSIONPercutaneous screw fixation for the treatment of pelvic fractures under fluoroscopy has several advantages such as less trauma, less blood loss, fewer rates of complications, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but it needs adequate preoperative preparation and high requirements for the surgeon.

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.
