Objective To explore the anti-depression mechanism of Kai-Xin-San(KXS)via regulation of neurogenesis in hippocampus of depression-like mice.Methods The extracts of KXS were prepared and the anti-depression effects of KXS were evaluated by behavioral tests on chronic unpredictable mild stress(CUMS)induced depression-like mice.Evaluating depression-like behavior in CUMS mice through sucrose preference test,forced swimming test,tail suspension test,and other methods.Neurogenesis in hippocampus were determined by immunofluorescence assay.In addition,effects of KXS on regulating nestin expression and Wnt/b-catenin signaling pathway were explored by western blotting analysis.Amounts of cortisol,corticotropin-releasing factor(CRF),adrenocorticotropic hormone(ACTH),brain-derived neurotrophic factor(BDNF)and nerve growth factor(NGF)were determined by ELISA tests.Mouse primary neural stem cells(NSC)was used to evaluate the effect of KXS on promoting its proliferation by immunofluorescence assay.In addition,effects of KXS on regulating nestin and Wnt/β-catenin signaling pathway were also explored by Western blotting analysis.Results KXS significantly ameliorated the depression-like behaviors in presence of increased sucrose preference rate and decreased immobile time of tail suspension and forced swimming.KXS significantly promoted the neurogenesis in the hippocampus and expressions of nestin,reduced the expressions of cortisol,CRF,ACTH,increased the expressions of BDNF,NGF,and regulated Wnt/β-catenin signaling pathway.KXS also promoted the proliferation of NSCs and expressions of nestin,enhanced the translocation of b-catenin into nucleus,and regulated the expressions of proteins of Wnt/β-catenin signaling pathway.Conclusion KXS promoted neurogenesis in hippocampus and regulated Wnt/β-catenin pathway,which might contribute to its antidepressant effect.

Objective To investigate the beneficial effect of Kai-Xin-San combined with fluoxetine in improving depression-like behaviors on chronic unpredictable mild stress(CUMS)induced depression model mice.Methods The present study aimed to assess the potential of Kai-Xin-San in combination with fluoxetine to ameliorate depression-like behaviors in a CUMS induced mouse depression model.Behavioral tests,such as the sucrose preference test were employed to evaluate the efficacy of the treatment.Additionally,the levels of suppressed stress factors were measured using the ELISA method.The morphology of hippocampal tissue was evaluated using the HE staining method,Nissl Staining and TUNEL staining methods.Furthermore,western blotting analysis was utilized to determine the expression levels of proteins such as Caspase-3,and Caspase-9.Results The co-administration of Kai-Xin-San and fluoxetine resulted in a significant increase in sucrose preference rate in model mice.This effect was comparable to that of fluoxetine alone at the standard clinical dose.Furthermore,the combination treatment up-regulated the levels of suppressed stress factors,reduced the apoptosis of hippocampus induced by depression and regulated the apoptosis signaling pathway in hippocampus.Conclusion The combination of Kai-Xin-San and fluoxetine has been shown to be an effective treatment for depression-like behavior in animal models,resulting in a reduction in the required clinical dosage of fluoxetine.This effect may be attributed to the up-regulation of neurotransmitter expression,inhibition of stress axis activation,and central nervous inflammation.

With the development of our economy and the progress of science and technology,the comfort medicine of children in the perioperative period is gradually promoted.Comfort medicine not only eliminates the physical pain of children,but also avoids the permanent psychological trauma caused by oper-ation and anesthesia.The incidence of preoperative anxiety in children is higher than that in adults,which may have adverse effects on perioperative period and prognosis of children.The characteristics of parents of different children,such as parental anxiety level,parental education level,parental socioeconomic back-ground,family composition,ethnicity,language,and other factors will affect the preoperative anxiety level of children.Intervention measures such as parents'participation in guiding children's preparation for anesthe-sia,management of children's fasting and drinking,and presence at the induction of anesthesia can alleviate children's preoperative anxiety level.For children with disabilities,communication between parents and medical staff in the perioperative period and intervention management of children is important.Compared with the traditional preoperative preparation program,the internet-based family preoperative preparation plat-form provides a comprehensive,effective and personalized information guidance for the families of children,ensuring the comfortable perioperative medical treatment of children.

Objective To investigate artemin and its receptors GFRα3 expression in human pancreatic ductal adenocarcinoma and its significance. Methods Expression and distribution of artemin and GFRα3 in 100 cases of human pancreatic ductal adenocarcinoma(PDAC) and 40 cases of normal pancreatic tissue were detected by immunohistochemistry and RT-PCR, quantitative RT PCR. Relations of artemin and GFRα3 with clinicopathological characteristics, especially nerve invasion were analyzed. Results Nerve invasion was detected in 64 out of 100 cases of PDAC, and the rate of nerve invasion was 64%. The ratio of expression of Artemin, GFRα3 protein in PDAC/normal pancreatic tissue was 2.697 ± 0.231 and 2.599 ± 0.588; the ratio of expression of Artemin, GFRα3 mRNA was 7.01 and 4.63. Artemin and GFRα3 expression were associated with tumor location, differentiation degree, TNM staging, nerve invasion node metastasis, but it was not associated with age, sex and tumor size. Artemin and GFRα3 expression was more positively expressed in cancer cells close to nerve tissue than cells far from nerve tissue. Conclusions Artemin and GFRα3 were involved in the development of pancreatic cancer and their high expression was closely related to perineural invasion.

ObjectiveTo determine the peripheral serum expressions and clinical value of carcinoembryonic antigen (CEA) and carbohydrate antigen CA19-9,CA242,CA72-4 and a single sialic acid ganglioside (CA50) antigen in advanced pancreatic cancer patients treated by three-dimensional conformal radiotherapy (3D-CRT) combined with endogenous field hyperthermia.Methods60 patients inoperable,advanced pancreatic cancer were treated by 3D-CRT combined with endogenous field hyperthermia.Radiation dose (DT) was 46 ～ 66 GY/23 ～ 33 F.Hyperthermia temperature was 41 ～ 43 ℃ 2 times/week,lasted 60 min each time.The expressions of CEA,CA19-9,CA242,CA72-4 and CA50 in peripheral serum were detected by Electrochemiluminescence immunoassay (ECLIA) every 2 weeks during treatment,and correlation were analyzed with tumor diameter,clinical stage,lymph node metastasis.Results From the 8th week,with 3D-CRT combined with endogenous field hyperthermia ongoing,CEA,CA19-9,CA50 andCA242 expression levels showed a gradual decline.CEA,CA19-9,CA50 and CA242 expression levels were (6.22 ± 2.71 ) μg/L,(43.44 ± 12.93 ) μg/L,(23.21 ± 7.71 )g/L and (24.26 ± 8.92) μg/L in 6 weeks,respectively.The difference was statistically significant among week 6 and week 0,week2,week 4 ( P ＜0.05),however there was no significant difference between week 6 and week 8 ( P ＞ 0.05 ).The CA724 expression did not change significantly ( P ＞ 0.05 ).There were positively correlation between CEA,CA199,CA50 and CA242 with pancreatic cancer tumor size,clinical stage and lymph node metastasis( respectively r =0.877,0.725,0.826,all P ＜ 0.01 ),however CA72-4 had no correlations ( P ＞ 0.05).ConclusionsCEA,CA19-9,CA50 and CA242 expressions in peripheral serum of pancreatic cancer patients were closely related to the treatment.Their joint detection can be served as independent objective evaluation reference information for the treatment efficacy and prognosis.

Objective To investigate the effects of artemin and its receptor GFRα - 3 on the invasion and metastasis of pancreatic cancer cells. Methods Human pancreatic cancer cell line MIA PaCa -2 was used in this study. Transwell cell culture chamber assay in vitro was used to detect the ability of invasion and metastasis of MIA PaCa -2 cells. The influence of artemin and GFRα -3 on the protein expression of MMP-2 and E-cadherin was investigated by Western blot and quantitative real time polymerase chain reaction-analyses (Q-RT-PCR). Results As the increase of artemin and GFRα -3, the invasion and metastasis of MIA PaCa- 2 was markedly increased [ 150 ng / ml concentration: Artemin group: 107.4 ± 11.4;GFRα3 group:94. 4 ± 9. 3 ;control group:34. 6 ± 7. 3, P < 0. 01 ]. With 150 ng / ml artemin and GFR-3,the synthesis of MMP-2 in MIA PaCa 2 cells was significantly increased than that in control group[ Artemin grou: (2. 17 ± 0. 05 ) × 108; GFRα3 group: (2. 02 ± 0. 03 ) × 108; control group: ( 1.02 ± 0. 02 ) × 108, t =6. 35,7. 32 ], while E-cadherin significantly decreased [ Artemin group: ( 0. 65 ± 0. 04 ) × 108; GFRα3 group: (0. 74 ± 0. 01 ) × 108; control group: ( 1. 36 ± 0. 03 ) × 108, t = 4. 27,5.61 ], the difference was statistically significant ( P <0. 01 ). Conclusions Artemin and its receptor GFRα3 could promote pancreatic cancer cell invasion and metastasis. This effect may be related to the up-regulated expression of MMP-2 and down regulated expression of E-cadherin.
