1.Updates on type 2 innate lymphoid cells and allergic diseases
International Journal of Pediatrics 2017;44(3):193-195
Innate lymphoid cell is a type of immune cells that lineage-negative,but can be stimulated to produce inflammatory cytokines that people discovered in recent years.It can be classified into three classes (ILC1,ILC2,ILC3),according to its different functions.Type 2 innate lymphoid ceils(ILC2)have attracted much attention because it is closely related with parasites and asthma and other allergic diseases.This review focuses the ILC2 phenotypes and the discovery,distribution,relationships with disease.

To investigate the apoptotic effect of free fatty acids (FFAs) on human ovary granulosa cells, the granulosa cells were treated with FFAs in various concentrations for three days, and then the cell viability was determined by trypan blue exclusion method. DNA fragmentation was examined by DNA ladder formation and Annexin V GFP/PI staining of the cells. We also determined if the apoptotic effect of saturated FFAs was mediated by their acly CoA metabolites and measured the expression of apoptosis related genes, Bcl 2 and Bax by Western blot. The results indicated that saturated FFAs induced apoptosis of granulosa cell by their acly CoA metabolites in a dose dependent manner, and led to the down regulation of Bcl 2 and the up regulation of Bax. It is concluded that saturated FFAs can induce apoptosis of human ovary granulosa cells, suggesting that the sexual disorder of obese and insulin resistant women is related to it.

Objective To investigate the role of vascular endothelial growth factor (VEGF) and transforming growth factor-α (TGF-α) in the angiogenesis of condyloma acuminatum (CA). Methods Tissue specimens were obtained from the lesions of 30 patients with CA and foreskin of 15 normal human controls. Reverse transcription (RT)-PCR and immunohistochemical method were utilized to measure the protein and mRNA expressions of VEGF and TGF-α in the specimens. Microvessel density (MVD) was determined by staining with anti-CD34 polyclonal antibodies. Results A statistical elevation was observed in the expression of VEGF and TGF-α mRNA as well as MVD in CA specimens compared with the normal control specimens (P < 0.001, 0.001, 0.01). The expressions of VEGF and TGF-α protein were observed in 90% and 86.7% of the CA specimens, and in 40% and 26.7% of the control specimens (both P < 0.01). MVD was positively correlated with the expression of VEGF and TGF-α protein in CA tissues (both P < 0.01). Conclusion The overexpression of VEGF and TGF-α in CA tissue may accelerate angiogenesis in, and participate in the development and progression of, CA.

Objective To investigate the effects of antidepressant therapy on whole regulating function of OPG/RANKL/RANK system in ovariectomized (OVX) rat model with depressive disorder.Methods Forty sexually mature female SD rats were used as subjects.The rats were randomly divided into 8 groups as following:sham group(Sn),depression group(Dn),the OVX group (On),the OVX with depression group(ODn),OVX with depression +sertraline group (ODs),and OVX with depression + citalopram (ODx),OVX with depression + reboxetine group(ODr),OVX with depression + venlafaxine group (ODw).Bilateral oophorectomy was applied to establish the ovariectomized rats model.Chronic unpredictable mild stress(CUMS) was used to estalish depression model.Open-field test and sugar consumption experiment were applied before the experiment and the 28th day of the experiment.Immunohistochemistry and Quantitative Real-time PCR were used to observe the expression of OPG,RANKL and RANK.Results After chronic unpredictable mild stress the scores of horizontal motion,vertical motion and percentage of sugar consumption experiment in Dn group were decreased contrast to the in control Sn group (P<0.05)and the scores in ODn group were decreased in contrast to the On group (P<0.05).The protein and gene expression of RANK in Dn group and On group were increased in contrast to the Sn group (P<0.05).The protein and gene expression of RANKL in Dn group and On group were increased in contrast to the Sn group (P<0.05).The gene expression of OPG in ODs group(5.94±0.79),ODw group(5.99± 1.08) and ODr group(6.59±0.69) was decreased in contrast to the ODn group (4.96±0.51) (P<0.05).The gene expression of RANK in ODs group (2.82±0.23),ODx group(3.03±0.04) was increased in contrast to the ODn group(3.44±0.18) (P<0.05).The gene expression of RANKL in ODs group(4.82±0.94),ODx group(5.00±0.82) and ODw group(5.23±0.88)was decreased in contrast to the ODn group (3.69± 0.69) (P<0.05).Conclusion The expression of RANK and RANKL in femoral neck is increased both in depressive disorder model rats and ovariectomized model rats.The antidepressant can up-regulate the expression of RANK,and down-regulate the expression of OPG and RANKL in the OVX with depression group.Of the effect,sertraline is the strongest,however reboxetine mesylate is the poorest.

Objective To investigate the effect of nitric oxide (NO) on the scratching behavior evoked by substance P (SP) in mice. Methods Forty BALB/c mice were randomly divided into 5 groups to receive intradermal injection of different doses of SP (0, 20, 40, 80, 160 nmol/site) into the rostral part of the back to establish the acute itch model. Another 40 mice were randomly allocated to model, spantide, L-arginine,L-NAME and aminognanidine groups injected intracutaneously with normal saline (NS), spantide, L-arginine,L-NAME and aminoguanidine, respectively, 10 minutes before SP (80 nmol/site) injection. Subsequently,the scratching behavior was observed, iNOS expression and NO level in the injected skin were detected by immunohistochemical staining and nitrate reductase assay, respectively. Results The scratching bouts per hour induced by intradermal NS and SP of 20, 40, 80 and 160 nmol/site were 4.38±4.07, 5.38±3.78,12.75±6.52, 23.50±7.84 and 42.38±15.84, respectively, and only SP at higher doses (40 - 160 nmol/site)elicited a dose-dependent scratching response in mice (P < 0.01 or 0.05) compared with NS. The scratches over 1 hour in SP, L-arginine, spantide, L-NAME and aminognanidine group were 67.13±32.79, 70.75±34.80, 10.75±8.14, 29.00±21.19 and 35.38±22.83, respectively; of them, pretreatment with spantide,L-NAME and aminognanidine significantly inhibited SP-induced scratching (P < 0.01 or 0.05), but L-arginine showed no inhibitory effect (P > 0.05). Compared with SP, the pretreatment with spantide, L-NAME and aminoguanidine significantly downregulated the iNOS expression and NO content (P < 0.01 or 0.05) in the injected skin other than L-arginine (P > 0.05 ). Conclusion Intradermal SP could increase NO synthesis by neurokinin 1 receptor activation, resulting in the scratching behavior in BALB/c mice.

Purpose To study the status of EGFR mutations and the expression of excision repair cross-complementation group 1 ( ER-CC1) and Ki-67 protein in patients with non-small cell lung cancer (NSCLC) and to examine the relationship between their expression and clinicopathologic features. Methods EGFR mutations were analyzed with DNA sequencing, and the expression of ERCC1 and Ki-67 protein was examined by immunohistochemistry EnVision. The relationship of EGFR mutations with the expression of ERCC1and Ki-67 and the clinicopathological features were analyzed. Results EGFR mutations were detected in 143 (143/291, 49. 1%) of the 291 specimens. EGFR mutations were found more frequently in women, non-smokers and adenocarcinoma. The difference of EGFR muta-tion rate between the histological subtypes according to the IASLC/ATS/ERS classification of lung adenocarcinoma was significantly ( P=0. 008). The mean tumor diameter was smaller in patients with EGFR mutations than in those with wild-type EGFR (P=0. 020). EGFR mutations were not related to age, lymph node metastasis. However, EGFR mutations were not related to the expression of ER-CC1 and Ki-67 protein (P>0. 050). Conclusions EGFR mutation is closely linked to several clinicopathological factors, such as gender, differentiation, and histological subtype. There is heterogeneity of EGFR mutation in patients with NSCLC. EGFR mutations were not related to the expression of ERCC1 and Ki-67 protein.
