In recent years,targeted drug delivery system as one of the hottest areas in pharmaceutical research has received more and more attention.However,the targeted anti-tumor drug delivery system has many shortcomings including low targeted efficiency which limit its clinical application.Elevating tumor targeting efficiency has become the bottleneck of nano-drug development and clinical application.Therefore,it is urgent to design and develop novel targeted drug delivery vehicle.Recent studies showed that mesenchymal stem cells (MSCs) have characters of tumor tropism and migration,which make them as ideal targeted anti-tumor drug delivery carriers for the treatment of solid and metastatic tumors.This paper reviews the progress in using MSCs as targeted anti-tumor drug delivery carrier,recapitulates the problems and challenges of the system,and proposes a solution for these problems.

Aim To observe the expression of migration inhibitory factor (MIF) in the enteric neurons,and to explore the nervous regulation on MIF activity in experimental colitis.Methods Colitis was induced in sensitized rat and mouse by 2,4-dinitrochlorobenzene(DNCB)enema.MIF activity was measured both in the mesentery lymphocyte(by MTT)and in the enteric neurons(by immunofluorescence double staining).6-OHDA was intraperitonealy (ip) administered to mouse before DNCB treatment.Norepinephrine(NE) was added to lymphocyte culture in vitro during MIF preparation.Results The expression of MIF protein in enteric neuron was increased in DNCB-induced colitis in rat.ip 6-OHDA in colitis mouse(38～150 mg?kg-1) resulted in a further increase of MIF activity than ip vehicle in colitis mouse (P

Objective To investigate the status quo of transformational leadership,psychological empowerment,team psychological safety and team effectiveness,and test whether the supposed structural equation is tenable.Methods Totally 380 nurses completed the Transformational Leadership Questionnaire,Psychological Empowerment Questionnaire,Team Psychological Safety Questionnaire and Team Effectiveness Questionnaire,structural equation model was used to verify the relationship of the above,Bootstrapping confidential interval and product of coefficient were used to test the mediating effect.Results Significant correlations were found between transformational leadership,psychological empowerment,team psychological safety and team effectiveness (P ＜ 0.01),transformational leadership played indirect effect on team effectiveness (Z=6.195,P ＜ 0.05),psychological empowerment and psychological safety had a totally mediation effect.Conclusions Healthcare workers should make psychological empowerment and team psychological safety as the breakthrough point,fully play the advantages of transformational leadership on team effectiveness in order to increase the working ability of nurses and make them complete the clinical work effectively and with high quality.

Objective:To explore the pathologic mechanism of blood-stasis syndrome in cardiopathy(BSSC) and its different syndrome types from the activity of fi brinolytic system.Methods:72 cases with BSSC,20 cases with non-blood-stasis syndrome in cardiopathy(NBSSC) were observed at random,20 healthy cases as control.The levels of tissue-plasminogen activator(t-PA) and plasminogen activator inhibitor-1(PAI-1) in blood plasma were detected by ELISA.Results:①The level of t-PA in the group of BSSC was signifi cantly lower than that in the groups of healthy control and NBSSC(P

OBJECTIVE:To study the hemostatic,antipruritic,and anti-crissal ulcer effects of Zhishuxi lotion.METHODS:The experimental animals were randomized into four groups(normal control group,Mayinglong-branded musk hemorrhoid ointment,Zhishuxi lotion high-dose group and low-dose group).The time needed to stop bleeding in all groups were tested by cutting mouse tail;the itch-threshold in each group of guinea pigs was determined by inducing itch with histamine phosphate;and the ulceration was observed by causing crissal ulceration in mice with acetic acid.RESULTS:Zhishuxi lotion could shorten the bleeding time,increase the itch threshold in guinea pig,and had some curative effect on acetic acid-induced crissal ulcer in mouse,as compared with the control group.CONCLUSION:Zhishuxi lotion has re-markable effects of hemostasis,itch-relief and anti-crissal ulceration.

ObjectiveTo investigate the effects of Tai Chi exercise on somatic function of middle-aged females.Methods60 middle-aged females had a 16-week Taichi quan exercise and changes of blood pressure, resting heart rate and vital capacity were tested.ResultsAfter Tai Chi exercise, 60 women had results of resting heart rate and blood pressure decreased, and vital capacity increased obviously (P<0.05～0.01).ConclusionTai Chi exercise maybe an effect sport manner to improve the somatic function of middle-aged females.

OBJECTIVETo explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.

METHODSForty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.

RESULTSCompared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).

CONCLUSIONSEA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.
