The non-coding miRNA is classified into different families according to their gene structure and function.It is involved in many cellular processes,such as proliferation,differentiation and apoptosis.Recently it has been proved that miRNA has played an important role in the pathogenesis of many cancers,acting as oncogenic miRNAs or tumor suppressor,including acute lymphoblastic leukemia (ALL).Because miRNA is highly connected with the pathogenesis,diagnosis,prognosis and drug-resistant of childhood ALL,it might be a new breakout for the diagnosis and treatment of ALL.This paper reviews current literatures on miRNA and childhood ALL.

Clinical treatment shows little significance for some terminal tumor in practice,in which case hospice care seems to be particularly important.During the application of modern nursing ethics to hospice care,some aspects should be bared in mind,including trying to meet the demand of patients and their family members,showing enough respect for their right to choose,and appropriately instructing death education.Meanwhile,communication and cooperation with other medical staff should also be stressed during hospice care.

There are a wide variety of spiders on the earth and most them can secrete venom,which contains a variety of chemi-cal compositions that have multiple influences on organism be-sides toxic effects.The pharmacological efficiency includes cardi-ovascular and cerebrovascular activities,analgesic activities,an-tibacterial and anticancer activities etc.Ion channels are one of the important targets of spider toxins.They act on different ion channels,such as potassium channel,calcium channel and differ-ent subtypes of sodium channels.Therefore the spider toxins pres-ent different pharmacological activities and potential medicinal value.The venoms of spiders are less well studied than those from other venomous taxa such as conotoxin,scorpions and snakes etc. However,in recent years,spider toxins are turning to a new hot subject in related research areas.This review summarizes the lat-est progress in biological activities of spider toxins as well as its application in medical practice and development.

Objective To discuss the intervention effect of four oral care model on compliance of atomizing inhalation and mouth and throat complications in outpatient infants and young children patients. Methods A total of 480 cases of children patients using budesonide inhalation for the treatment of respiratory tract infection were divided into the observation group(n=260)and the control group (n=220) according to the time sequence. The control group received conventional nursing, the observation group used quaternity oral care model in nursing care. The compliance and occurrence of complications in the mouth and throat were observed between the two groups. Results In the observation group with nebulae inhalation compliance was 79.2% (206/260), evidently higher than that in the control group the compliance of 58.6%(129/220) (χ2=23.97,P<0.01). The incidence of oral herpes and ulcers in the control group was 2.73%(6/220), and 0.77%(2/260) in the observation group, but no significant difference was seen (χ2=2.79, P>0.05). The incidence of thrushes was 3.64%(8/220) in the control group, and none occurred in the observation group, which showed significant difference (χ2=9.62, P<0.01). Conclusions Using quaternity oral care model in corticosteroid nebulae inhalation patientscan increase compliance and decreasecomplications of oral and throat of outpatient children.

Objective To explore the positive effects of dancing train to self-esteem and social function in chronic schizophrenia patients.Methods By random sampling,40 male and 40 female chronic schizophrenic inpatients with dancing train were enrolled as the research group in our study training.According to gender,age,education,diagnosis,hospital stays and other factors,80 inpatients without dancing train were enrolled as the control group by paired choice.Both groups were evaluated with Self-esteem Scales (SES) and Scales of Social Practice of Inpatients (SSPI) at pre-and post-training.Results Comparison between the research group and control group showed that it had no significant difference between every value of scales in male and female before training; after training the research group's every indicants was better than that of the control group,and there were significant differences.Compared between pre-and post-training,the research group had significant differences but the control group did not.Before training,no significant differences between male and female of the research group.Compared with male inpatients,females achieved significantly better scores in SES,SSPI and 2 items of daily living and positive social communication after dancing train for 8 weeks.There were significant differences between male and female inpatients in SES,SSPI and 3 items of SSPI at pre-and post-train.Conclusions Dancing train can be effective to the residue symptoms in schizophrenic patients and improve social function and self-esteem of male and female inpatients.

Type 2 innate lymphoid cells ( ILC2s) are recently identified members of the innate lymphoid cell ( ILC) family. These cells are capable of producing Th2-type cytokines such as IL-5 and IL-13 in response to epithelial cell-derived cytokines IL-25 and IL-33 and play critical roles in allergic diseases such as bronchial asthma. Further investigations on ILC2s will enhance the better understanding of type 2 immune responses and may provide new strategies for the treatment of allergic asthma. In this review, we fo-cus on the origin, location and biological function of ILC2s as well as their possible roles in the pathogenesis of bronchial asthma.

Objective To investigate the application effects of new-type glove constraint in intensive care unit. Methods A total of 113 eligible patients were randomly divided into two groups by random digits table method, of which 59 patients used the traditional restraint for body constraint in the control group while 54 patients applied the new-type glove constraint in the treatment group. The skin conditions of restraint position, tube coming off and the satisfaction of patients and relatives were compared between two groups. Results The incidence of skin abnormality at restraint position was 0 in the treatment group and 13.6%(8/59) in the control group. The difference had statistical significance (χ2=7.880, P<0.01). The satisfaction of patients and relatives was 33.3%(18/54) in the treatment group and 5.1%(3/59) in the control group, and the difference had statistical significance (χ2=16.619, P<0.01). Conclusions The use of new-type glove constraint may give a maximum activity space to patients;reduce patient′s psychological adverse impacts;and decrease the skin and body damages. It is worthy of clinical promotion and application.

Objective:The current study investigated the effects of nesfatin-1 in the hypothalamic paraventricular nucleus (PVN) on gastric motility and the regulation of the lateral hypothalamic area (LHA).Methods:The projection of nerve ?ber and expression of nesfatin-1 were observed by retrograde tracing and fluo-immunohistochemistry staining;The nuclei microinjection and nuclei electrical stimulation,extracellular discharges of single unit neuron were used to observe the effects of nesfatin-1 on the GD neurons;Gastric motility recording in vivo were used to monitor the effects of nesfatin-1 on the amplitude of constriction and frequency of gastric motility in conscious rats.Results:Nesfatin-1 inhibited the majority of the GD-E neurons(1.97± 0.12 Hz vs.1.15± 0.07 Hz) and excited GD-I neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) in the PVN,which were weakened by oxytocin receptor antagonist H4928 (GD-E:1.38± 0.08 Hz,P＜0.05 vs.nesfatin-1;GD-I:2.49± 0.15 Hz,P＜0.05 vs.nesfatin-1).Gastric motility experiments showed that administration ofnesfatin-1 in the PVN decreased gastric motility.Retrograde tracing and immunofluorescent staining showed that nucleobindin-2/nesfatin-1 and fluorogold double-labeled neurons were observed in the LHA.Electrical LHA stimulation excited the firing rate of GD-responsive neurons (GD-E:2.06± 0.12 Hz vs.4.23± 0.21 Hz,GD-I:1.61± 0.09 Hz vs.4.83± 0.25 Hz) in the PVN.Pre-administration of an antinucleobindin-2/nesfatin-1 antibody in the PVN strengthened gastric motility,decreased GD-E neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) and excited the discharging of the GD-I neurons(4.15± 0.18 Hz vs.4.83± 0.25) induced by electrical stimulation of the LHA.Conclusion:Nesfatin-1 in the PVN could serve as an inhibitory factor to inhibit gastric motility,which might be regulated by the LHA.

In order to improve the interfacial bonding strength of hydroxyapatite/polyurethane implanted material and dispersion of hydroxyapatite in the polyurethane matrix, we in the present study synthesized nano-hydroxyapatite/polyurethane composites by in situ polymerization. We then characterized and analyzed the fracture morphology, thermal stability, glass transition temperature and mechanical properties. We seeded MG63 cells on composites to evaluate the cytocompatibility of the composites. In situ polymerization could improve the interfacial bonding strength, ameliorate dispersion of hydroxyapatite in the properties of the composites. After adding 20 wt% hydroxyapatite into the polyurethane, the thermal stability was improved and the glass transition temperatures were increased. The tensile strength and maximum elongation were 6.83 MPa and 861.17%, respectively. Compared with those of pure polyurethane the tensile strength and maximum elongation increased by 236.45% and 143.30%, respectively. The composites were helpful for cell adhesion and proliferation in cultivation.
