Currently refractory and relapsed mantle cell lymphoma (MCL) continues to develope a poor prognosis, and the treatment remains a significant clinical challenge. The use of bortezomib in clinic provides a novel method for the treatment of refractory and relapsed MCL. This review summarizes the mechanism and efficiency of bortezomib in the treatment of MCL and the strategies for overcome of bortezomib resistance.

According to Traditional Chinese Medicine, the functional structure of human body is composed of five functional subsystems which are based on the five-organs concept, and the relationship between them could be expatiated with Wu-Xing (Five-Elements) theory. Wu-Xing system is taken as our research object. The dynamic model has the characteristic of self-organization. There is only one stable point with local stability in the five-dimensional space. There exists an instability domain in the five-dimensional space. The stability domain is unbounded; it contains some special subdomains, including rectilineal subdomains, ray subdomains and line subdomains. In some ray subdomains, there exists comeback summits, the peak value of the comeback summit is comeback threshold. The existence of the comeback threshold means that, if the human body wants to go back to the healthy state from a certain special state which corresponded to the initial conditions located in a domain with comeback summit, it has to get across the comeback threshold. The comeback threshold is the division of the healthy state and the sub-healthy state. Some research work is done to investigate the response of the Wu-Xing dynamic model to the impact stimulation, and results in the decrease of the system's comeback threshold. There are 3 manners to achieve this goal, and they tally with the principle of the Wu-Xing system and the experimental rules in clinic.

Primary lymphoma of bone (PLB) refers to non-Hodgkin lymphoma (NHL),which is an uncommon extranodal lymphoma,accounting for 1 % of all NHL,5 % of extranodal lymphoma and 7 % of primary bone tumor. Currently,the diagnostic criteria of PLB includes a primary focus in a single bone; positive histological diagnosis; and no evidence of distant soft tissue or distant lymph node involvement. The diversity,hereditery,and lower incidence of PLB make it difficult to diagnose. In order to decrease the rate of misdiagnosis and missed diagnosis,the clinical,pathological,and imaging characteristics of PLB in this study are analyzed.

Objective To investigate the effects and safety of mechanical continue heart chest compression ventilation (CCV) and interrupt pressure ventilation (30∶2) on cardiopulmonary resuscitation (CPR).Methods According to the mechanical pressure ventilation different way,90 patients with cardiopulmonary resuscitation (CPR) in our hospital emergency center were admitted into control group (30∶2 group) with 48 cases and observation group (CCV group) with 42 cases,with a before and after case-control study to compare the recovery effects [rate of spontaneous circulation restoration (ROCS),successful recovery rate,the ROCS time,withdraw machine time,and Glasgow coma scale(GCS) in successful recovery patients] and recovery of adveme events (fracture,skin lesions,hemopneumothorax,and visceral injury).Results With comparison between two groups,CCV group had shorter ROCS recovery time and withdraw machine time [(9.31±4.32) min vs (12.67±4.86) min,(32.07 t4.84) min vs (36.33 ± 3.37)min,P ＜0.05],higher rate of ROCS and successful recovery rate (42.9％ vs 22.9％,21.4％ vs 6.3％,P ＜ 0.05) than 30∶2 group;while both were no difference in Glasgow coma scale (GCS) in successful recovery patients (P ＞ 0.05).The incidence of adverse events were not different in both (11.9％ vs 8.3％,P ＞0.05).Conclusions Mechanical continue chest compression ventilation (CCV) compared to interrupt pressure ventilation (30∶ 2) can effectively shorten the ROCS recovery time and withdraw machine time,improve the ROSC recovery rate and success rate of recovery,but failed to improve nerve functions.Two groups have a lower incidence of adverse events,which is safe to use.

Objective To compare the influence of cardiopulmonary bypass(CPB) on brain injury in the infants with compli‐cated congenital heart disease(CHD) and simple CHD by analyzing and monitoring the perioperative cerebral electric impedance co‐efficient ,serum S‐100βprotein and neuron specific enolase (NSE) .Methods Forty infants with CHD were randomly selected and divided into two groups:the complicated group(n=20 ,13 cases of tertralogy of fallot ,7 cases of transposition of great arteries) and the simple group(n=20 ,8 cases of atrial septal defect ,12 cases of ventricular septal defect) .Blood samples were taken and the cere‐bral electric impedance coefficients before operation(T1 ) ,at 10 min after CPB(T2 ) ,immediately after aortic clamping(T3 ) ,aortic o‐pening(T4 ) ,end of CPB(T5 ) ,at 5 h(T6 ) and 24 h (T7 ) after CPB were measured by the BORN‐BE noninvasive brain edema moni‐tor .Serum levels of S‐100βprotein and NSE were detected by ELISA .Results There was no statistically significant difference in the cerebral electric impedance coefficient ,S‐100βprotein and NSE before surgery(P>0 .05) .The cerebral electric impedance coef‐ficient ,S‐100βprotein and NSE were significantly increased from the beginning to the end of CPB(P< 0 .05) ,and gradually de‐creased after CPB(P<0 .05) .The cerebral electric impedance coefficient ,S‐100βprotein and NSE were obviously higher in the com‐plicated group than those in the simple group at the same time points(P<0 .05) .The cerebral electric impedance coefficient was re‐spectively correlated with S‐100βprotein and NSE .Conclusion The influence of CPB on brain injury in complicating CHD infants is more serious than that in simple CHD infants .The BORN‐BE noninvasive brain edema monitor can be used during CPB periopera‐tive period in complicating CHD infants for conducting the real time monitoring in order to reduce brain damage .

Objective; To elucidate the mechanism of the role of ER-a in fat metabolism by regulating the expression of ER-a in SD rats marrow mesenchymal stem cells during differentiating into adipocytes in vitro. Methods ;SD rats marrow mesenchymal stem cells were separated and cultivated. The ER-a was transfected into the rBMSCs in group one. Tamoxifen Citrate was used to restrain the expression of ER-a in group two, the group without any treatment was used as control. Western blot was used to identify the difference of ER-a expression among different groups and Oil-Red-0 staining was employed to identify the adipocytes in vitro. Results; There was significant difference between the number of lipids and different groups (P <0. 01) ,the number of lipid droplet changed concomitantly with ER-a: Low-expression ER-a group > Control group > High-expression ER-a group. Conclusion; ER-a in SD rats marrow mesenchymal stem cells may restrain the adipocyte differentiation.

With advancements in the field of cancer stem cells,the hypothesis that colon cancer originates from stem cells has not only been introduced but also receives substantial supports by separating a subpopulation of colon cancer cells through primitive cells markers.Unlike most non-tumourigenasis colon cancer cells,these tumor-initiating cells have many specific characters both in vitro and in vivo.An improved understanding of drug resistance based on cancer stem cells and molecular pathways that regulate proliferation and differentiation of gastrointestinal cancer stem cells could doubtless translate into new therapeutic strategies.

Various hypotheses have been put forward to explain the pathogenesis of hemorrhoidal diseases. However, the etiology and mechanisms of hemorrhoids are far from clear, and as a consequence the present therapeutic objective is just to relieve or abolish the symptoms of hemorrhoids. In this review, the recent research advances on the pathophysiological characteristics that are closely associated with hemorrhoids are analyzed and discussed, which include constipation, high anal resting pressure, anal mucosa damage, aging of the anal cushion supporting tissue, blood and vessel alterations, obstruction of microcirculation and biochemical changes.

Objective To know about the status quo and influencing factors of undergraduate nurses' psychological empowerment at present,and provide a theoretical basis for nursing administrators so as to take measures to raise the level of psychological empowerment of undergraduate nurses.Methods General information questionnaire for nurses,Psychological Empowerment Scale were used to survey 207 undergraduate nurses in 3 first class teaching hospital of Dalian City.Results Undergraduate nurses' psychological empowerment score was (43.890±6.515) points,four dimensions whose scores from high to low were self-efficacy,job significance,autonomy and job impact.There was statistical difference in terms of ages,working length,working positions,professional titles,working purposes and training opportunities.Among them,working position and working purpose were the most important influencing factors of psychological empowerment.Conclusions Psychological empowerment of undergraduate nurses needs to be improved,managers should pay attention to the role of psychological empowerment,and actively cultivate and correctly guide undergraduate nurses in order to stimulate their potential in work,and finally,promote the sustainable development of a solid nursing career.

Acute myeloid leukemia (AML) originates from rare leukemia stem cells (LSC).Because these chemotherapy-resistant LSC are thought to underlie disease relapse,effective therapeutic strategies specifically targeting these cells may be beneficial.With the increasing knowledge regarding the LSC,several major directions in targeted therapies with regard to LSC are being investigated.These include targeting cell surface molecules,signal pathways,and microenvironment of LSC.Since eliminating LSC-should provide an efficient,potentially curative treatment option for leukemia patients,this article reviews the recent progress of LSC targeting in AML therapy.
