1.Mesenchymal stem cells and tumor metastasis
Journal of International Oncology 2011;38(12):905-907
Mesenchymal stem cells (MSCs) have been found to home to tissues/organs with irflammation,the sites of growing tumors,as well as to participate in the formation of the tumor micro-environment,suggesting that MSCs play important roles in tumor growth and metastasis.To study the roles and mechanisms of MSCs in tumor growth and metastasis will provide new insights into tumorigenesis and tumor target therapy.
2.Research progress in parathyroid hormone-related protein and diabetic nephropathy
Chinese Journal of Endocrinology and Metabolism 2014;30(11):1009-1011
Parathyroid hormone-related protein (PTHrP) and its receptor type 1 (PTH1 R) are extensively expressed in the kidney,where they are able to modulate renal function.Animal and human studies have shown that PTHrP acts as an important mediator of diabetic renal cell hypertrophy by a meehanism which involves the modulation of cell cycle regulatory proteins and TGF-β1.Furthermore,angiotensin Ⅱ (Ang Ⅱ) appears to be responsible for PTHrP upregulation in these conditions.These findings provide novel insights into the well-known protective effects of Ang Ⅱ antagonists in renal diseases,paving the wav for new therapeutic approaches.
3.Incision choice of nipple-areola complex-sparing mastectomy
China Oncology 2016;26(5):367-371
With the development of surgical techniques, the use of nipple-areola complex (NAC)-sparing mastectomy (NSM) has been increasing. Except for oncologic safety, the aesthetic outcome of surgery is greatly concerned by clinicians and patients. So far, there has been no consensus on the incision of NSM. This article reviewed the literature so as to provide some evidence for the selection of NSM incision.

Objective To explore the influence of blocking B7/CD28 co-stimulatory pathway by RNA interference on the rejection response in mice heterogeneous heart transplantation and its mecha- nism.Methods siRNA of which sequence specified to CD80 and CD86mRNA was synthesized in vitro respectively and transfected into donor derived myeloid dendritic cells (DCs).The expression levels of CD80 and CD86 mRNA and surface antigen CD80,CD86 were assayed by semi-quantitative reverse transcription polymerase chain reaction and flow cytometry before and after CD80siRNA and CD86siRNA transfection.Seven days prior to heterogeneous heart transplantation in mice,DCs modi- fied by siRNA were transfused into recipients intraveneously (DC interference group).At the same time,group of allograft transplantation,cyclosporine A (CsA)-treated (CsA injected subcutaneously postoperatively,5 mg.kg~(-1)?d~(-1)) group,group of isograft transplantation,and non-interference DC group (transfusion of non-interfered DCs pre-transplanting) were assigned.The graft survivals were individually recorded and the graft rejection grading was pathologically evaluated.Interleukin 2 (IL- 2),interferon?(IFN-?),and IL-10 mRNA expression levels in grafts tissue were determined.Results After siRNA transfected into DC,the expression levels of CD80 and CD86 mRNA were down- regulated significantly and the the antigen CD80~+ and CD86~+ reduced from 84%,67% to 35% and 30% respectively.As compared with groups of allograft and non-interference DC,survival of the grafts was significantly longer in DC interference group (P<0.01),pathological grade of rejection significantly lower (P<0.01),IL-2 and IFN-?mRNA expression levels lower,and IL-10 mRNA ex- pression levels higher in grafts tissue (P<0.01).Conclusion Knocking down the molecule B7 expres- sion level in donor-derived myeloid DCs through RNAi,which could block B7/CD28 co-stimulatory pathway,could exhibit inhibitive effect on rejection response in mice heart transplantation.The mechanism might be due to induction of T lymphocyte anergy and Th cell differentiation deviating to T_H2.

Objective To summarize the nursing key points in nursing ovarian cancer patients with early postoperative inflammatory intestinal obstruction after non-surgical treatment value. Method The nursing data of 32 ovarian cancer patients with early postoperative inflammatory intestinal obstruction in our department in January 2010 to October 2016 were retrospectively analyzed. Results About 32 patients were treated with non-surgical treatment, cure time within 2~30d, averaged (7.80 ±5.98)d. No intestinal obstruction happened after resuming to normal exhaustion, defecation and dieting. Conclusion Such nursing measures as psychological nursing, gastrointestinal decompression nursing, nutrition support nursing and auxiliary therapy like promoting peristalsis recovery are key to the increase of cure rate of early postoperative inflammatory intestinal obstruction.

Objective To explore the antiepileptic effect and mechanism of glucocorticoid. Methods Animal behaviour observation and immunocytochemical staining. Results Major epilepsy was induced by pentylenetetrazole(PTZ).Dexamethasone or diphenylhydantoin(DPH) administered in rat 30?min before administration of PTZ could suppress or inhibit epileptiform.Immunocytochemistry demonstrated that there was a large number of hypertrophic astrocytes with GFAP immunoreaction in cerebral cortex,hippocampal gyrus and dentate gyrus of epileptic rats induced by PTZ.The immunoreaction of GFAP was obviously weakened,the number of positive cells was reduced,the processes were shorter and less in both groups of antiepilepsy by GC or DPH.The expression of Fos protein was in a great quantity in cerebral cortex 1 to 1\^5 hours after seizure induced by PTZ,whereas their expressions were remarkable suppressed in GC or DPH antiepileptic groups. Conclusion 1\^The antiepileptic effect of GC was further proved by comparing with the antiepileptic effects of DPH(a traditional antiepileptic drug). 2\^Inhibited activity of astrocytes might be involved in antiepileptic mechanism of GC. 3\^The change of expression of Fos protein might be closely related to epileptic actions.

Objective To investigate the distribution of interleukin\|2 receptor (IL\|2R) and glucocorticoid receptor(GR) and identify coexistence of IL\|2R and GR in the rat brain. Methods The double labeling immunocytochemical technique(PAP method combined with ABC method), DAB and BDHC were used in the double labeling immunocytochemical method as the chromogens respectively. The reactive products of former was brown or yellow and later was black blue. Results IL\|2R and GR positive neurons were widely distributed in the cerebral cortex, hippocampus, thalamus, many motor and sense nuclei in the brain stem. The immunoreactive products of IL\|2R were found to be located on cell membrane and GR in nucleus and cytoplasm. There were a lot of positive double labeling neurons in the rat brain. The rate of double labeled cells in the total number of positive cells varied in different regions of brain, such as, 50 percent in cerebral cortex and 30 percent in nucleus of abducent nerve. Conclusion Immunogical cytokines and hormone could regulate the neuronal function through their corresponding receptors which coexisted in the same brain neurons. The present study might provide morphological evidence in the level of receptor for the immuno\|neuro\|endocrine network.

Objective To evaluate the usage situation and the trend of traditional Chinese medicine injection for activating blood circulation in our hospital. Methods The sales amount and drug use frequency (DDDs) and drug utilization index (DUI) of traditional Chinese medicine injection for activating blood circulation were sorted and analyzed in our hospital from the fourth quarter of 2011 to the third quarter of 2012. Results The total sales amount of traditional Chinese medicine injection for activating blood circulation gradually increased in our hospital during that time. The proportion of varieties with the ratio DUI sum/DDDs sort of closed to 1 (0.75≤order ratio≤1.25) in the three quarters of 2012 accounted for 53.33%, 53.33%, and 66.67%, respectively. This indicated that the usage of traditional Chinese medicine injection for activating blood circulation was more unreasonable, but tended to be reasonable. Conclusion The usage of traditional Chinese medicine injection for activating blood circulation was basically rational in our hospital, and efficacy of clinical pharmacist intervention was obvious. Effective and safe evaluation of traditional Chinese medicine injection can be further strengthened, in order to improve the efficacy and reduce the adverse reaction.
