Objective To investigate the relationship among the proliferation of CD4+T cells, the intracellular levels of interleukin-10 (IL-10) and transforming growth factor-?1(TGF-?1), and allergic bronchial asthma. Methods Dermatophagoides farinae antigen were prepared as allergen. Twenty-five patients with asthma and 15 healthy individuals were enrolled and divided into blank control group, allergen group and self control group, respectively, after venous blood sample collection. The proliferation of CD4+T cells and the distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 were measuredby flow cytometry (FCM). Results The distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 could hardly be detected in the peripheral blood samples of the blank controls of the patients with asthma and healthy ones. In the allergen group of the healthy individuals, the peripheral blood CD4+T cells were significantly proliferated, and the proportions of CD4+T cells andCD4+/IL-10+ cells were much higher than the self control group, while there was no significantly increase in the proportions of CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 subgroups. In the allergen group of those with asthma, the proportions of peripheral blood CD4+, CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 cells were not found significantly increased compared with those self controls. After being activated by allergen, the proportion of peripheral blood CD4+/IL-10+ cells was significantly lower in the patients with asthma than the healthy individuals(P

This study was aimed to observe effects of Albizia Julibrissin Flower Total Flavonoids (AJFTF) on the learning and memory abilities and plasma monoamine neurotransmitters 5-HT and NE content of depression model rats . A total of 90 SD rats were randomly divided into the normal group , model group , western medicine group ( Venlafaxine Hydrochloride 0 . 0125 g?kg-1 ) and high , middle and low dosage groups of AJFTF ( equivalent to the crude drug of 10 , 5 , 2 . 5 g?kg-1 ) . Depression model rats were induced by solitary cultiva-tion and chronic unpredictable stress . The learning and memory abilities of model rats were evaluated with the Morris water maze . And the plasma contents of 5-HT and NE were determined by enzyme-linked immunosor-bent assay ( ELISA ) . The results showed that AJFTF ( administered with high , middle and low dosage for 21 days ) significantly shortened the incubation period of the Morris water maze positioning and navigation ( P <0 . 05 or P < 0 . 01 ) , and increased the times of crossing the platform in space exploration ( P < 0 . 05 or P <0 . 01 ) . There was a certain dose-effect relationship . The AJFTF ( high , middle and low dosage ) increased the plasma contents of 5-HT and NE ( P < 0 . 05 ) . It was concluded that AJFTF can improve learning and memory abilities of depression model rats which indicates that AJFTF have potential antidepressant effects . Its action mechanism may be related to increase plasma monoamine neurotransmitter content of 5-HT and NE .

Objective:To investigate the regulatory effects of acupuncture and moxibustion on chromatin remodeling complex core catalytic subunit of Brahma-related gene 1(Brg1),histone deacetylase(HDAC)3,HDAC9,and males absent on the first(MOF)in the colon tissue of rats with Crohn disease(CD). Methods:Using the random number table method,60 male Sprague-Dawley rats were divided into 5 groups,including a normal group,a model group,an acupuncture group,a medicinal cake-insulated moxibustion group,and an acupuncture-moxibustion group,with 12 rats in each group.CD rat models were prepared using 2,4,6-trinitrobenzene sulfonic acid(TNBS)in all groups except the normal group.The normal and model groups received no interventions.In the acupuncture group,rats were intervened with acupuncture at bilateral Zusanli(ST36)and Shangjuxu(ST37),20 min/session,once a day.The medicinal cake-insulated moxibustion group received medicinal cake-insulated moxibustion at Qihai(CV6)and bilateral Tianshu(ST25)with 2 cones per point per session,once a day.The acupuncture-moxibustion group received both acupuncture and moxibustion interventions simultaneously.Each intervention was performed for 10 consecutive days.Observations included general condition,disease activity,macroscopic damage,and pathological changes in the rat's colon tissue.Real-time fluorescence quantitative polymerase chain reaction was used to measure the mRNA expression of chromatin remodeling-related enzymes Brg1,HDAC3,and HDAC9,while Western blotting detected the protein expression of Brg1,HDAC3,HDAC9,and MOF in rat's colon tissue. Results:The model group showed significantly increased diarrhea score,occult blood score,macroscopic damage score of colon tissue,and colon macroscopic damage index(CMDI)score,as well as elevated mRNA expression levels of HDAC3 and HDAC9,protein expression levels of HDAC3,HDAC9,and MOF,and decreased mRNA and protein expression levels of Brg1 compared to the normal group(P<0.01).In contrast,compared to the model group,the diarrhea score,occult blood score,macroscopic damage score,CMDI score,mRNA expression levels of HDAC3 and HDAC9,and protein expression levels of HDAC3,HDAC9,and MOF were significantly reduced(P<0.05 or P<0.01),while the mRNA and protein expression levels of Brg1 were significantly increased(P<0.01)in the acupuncture group,the medicinal cake-insulated moxibustion group,and the acupuncture-moxibustion group. Conclusion:Both medicinal cake-insulated moxibustion and acupuncture,either used alone or in combination,can regulate the abnormal expression of chromatin remodeling-related enzymes Brg1,HDAC3,HDAC9,and MOF in the colon tissue,thus reducing colon inflammation in CD rats.

OBJECTIVETo explore the effect of drug-containing serum of Chinese herbal compounds [Xiongshao Capsule (XS, for activating blood) and Huanglian Capsule (HL, for dispelling toxin)] on tumor necrosis factor-alpha (TNF-alpha)-induced adherence between human umbilical vein endothelial cells (HUVECs) and polymorphonuclear neutrophils (PMN), inflammatory reaction and expression of related proteins in mitogen-activated protein kinase (MAPK) pathway.
METHODSThirty-two rats were randomly divided into four groups (8 in each group) using random digit table: the blank control group treated with distilled water, the test group I treated with Chinese herbal compound of XS (0.135 g/kg), the test group II treated with Chinese herbal compound of HL (0.135 g/kg), and the test group Ill treated with Chinese herbal compound of XS (0.135 g/kg) and HL (0.135 g/kg). All medication was given by gastrogavage once a day for a week. Rats' blood serum was harvested 1 h after the last administration to prepare drug-containing serum. HUVECs were exposed to TNF-alpha (100 ng/mL) to induce cell injury model and incubated with corresponding drug-containing serum (10%) for 24 h. Normal rats' serum was given to cells in the blank control group and the model group, while XC + HL containing serum was given to cells in the rest 3 groups. The adherence of HUVECs and PMN cells was detected by using rose bengal strain. Levels of E-selectin, intercellular adhesion molecule-1 (ICAM-1), and interleukin-1beta (IL-1P) in the supernatant of cultured HU-VECs were determined by ELISA. Protein expressions of mitogen-activated protein kinases p38 (p38MAPK) and extracellular signal-regulated kinase 1/2 (ERK 12) were determined by Western blot.
RESULTSCompared with the blank control group, HUVECs were seriously injured; PMN adherence amount significantly increased; levels of E-selectin, ICAM-1, and IL-1beta increased; expression levels of p-p38MAPK and p-ERK 1/2 in the supernatant of HUVECs significantly increased in the model group (all P < 0.01). Compared with the model group, HUVECs-PMN adherence amount decreased (P < 0.05); levels of E-selectin, ICAM-1, and IL-1 beta in the supernatant of HUVECs decreased (P < 0.01, P < 0.05); expression levels of p-p38MAPK and p-ERK 1/2 of endothelial cells decreased in the test group I, II, and III (P < 0.01).
CONCLUSIONSDrug-containing serums of activating blood, activating blood and dispelling toxin could attenuate TNF-alpha induced injury of HUVECs, inhibit HUVECs-PMN adherence and the release of adhesion factors. Its mechanism might be involved with protein phosphorylation of p38MAPK and ERK 1/2 in the MAPK pathway.

OBJECTIVETo investigate the correlation between articulation, velopharyngeal function, and surgical age by comparing the changes in articulation after velopharyngeal closure is performed. This study is also conducted to investigate the influencing factors of omission change between pre- and post-operation.
METHODSA total of 48 patients, including 18 males and 30 females, mean age (13.3 ± 5.8) years, with non-syndromic cleft lips and palates were selected from January 2011 to December 2011. Their speech data and articulation between pre- and post-operation were retrospectively analyzed using non-parametric tests. Correlation study was performed to analyze the influencing factors of the changes in articulation. P < 0.05 was considered statistically significant.
RESULTSThe difference in articulation after velopharyngeal closure occurred was significant (Z = -3.796, P = 0.000). A negative correlation between the ratio of post-operative normal articulation and surgical age (R = -0.487, P = 0.000) was observed. The change in omission was positively correlated with surgical age (R = 0.589, P = 0.000) and gender (R = 0.404, P = 0.047). By comparison, the change in omission was negatively correlated with follow-up time (R = -0.235, P = 0.040).
CONCLUSIONArticulation and intelligibility are significantly improved after velopharyngeal closure is performed. These parameters are negatively correlated with surgical age to some extent. In addition, the change in omission is positively correlated with surgical age and gender, whereas the change in omission is negatively correlated with follow-up time.

Objective To study the therapeutic effect of recombinant adeno-associated virus carrying human endostatin gene therapy on endometriosis in mice model. Methods Recombinant adeno-associated virus vector carrying human endostatin gene and enhanced green fluorescent proteins gene (rAAV2-endostatin-EGFP) was constructed. Endometrium was from 12 patients with leiomyoma undergoing hysterectomy in Second Hospital, Tianjin Medical University between November and December 2008. Endometriosis models of nude mice were established by transplanting human endometrial fragments intooperitoneal surface. After 1 week, those 60 mice were divided into 3 groups: treatment group including 20 mice injected with rAAV2-endostatin-EGFP to ectopic lesion, control group including 20 mice injected with rAAV2-EGFP to ectopic lesion and blank control group including 20 mice injected with phosphate buffered saline (PBS) to the ectopic lesion. At 1, 2 and 3 weeks after treatment, those mice underwent laparotemy to observe the location and size of ectopic lesion in abdominal cavity. The expression of endostain protein, number of gland, microvessel density (MVD) and vascular endothelial growth factor (VEGF) were measured in ectopic lesions. The serum level of estradiol and progesterone were detected in nude mice among every groups. Results (1) All endometriosis of nude mice models were established successfully through peritoneum transplanting. After 1 week's treatment, flat lesion nodes, decreased gland number and narrow and atrophy glandular cavity were observed by light microscope. (2) The endostatin gene was transferred into nude mice successfully and expressed effectively. It was observed that endostatin protein expression was shown with enhanced green fluorescent proteins in ectopic lesion. (3) Glands number of ectopic lesion in rAAV2-endostatin-EGFP group(7.8±1.9,7.0±1.5 and 5.5±1.7) were significantly less than 10.1± 1.7, 10.2±2.0 and 9.8±2.4 in rAAV2-EGFP control group and 10.2±2.2,10.0±2.0 and 9.7±2.2 in PBS control group at 1,2 and 3 weeks after treatment(all P<0.05). Glands number of ectopic lesion in rAAV2-endostatin-EGFP group at 3 weeks was significantly less than those at 1 and 2 weeks after treatment (P<0.05). (4) MVD of ectopic lesion in rAAV2-endostatin-EGFP group (12.2±1.5,11.4±2.1 and 9.0±1.4) was significantly less than those at rAAV2-EGFP control group (16.5±1.7,16.5±1.9 and 16.9±1.9) and PBS control group (16.2±1.6,16.0±1.6 and 16.3±1.7) at 1,2 and 3 weeks after treatment (all P<0.05) . MVD of ectopic lesion in rAAV2-endostatin-EGFP group at 3 weeks was significantly less than those at 1 and 2 weeks after treatment(P<0.05). (5) The rate and density of VEGF expression at ectopic lesion in rAAV2-endostatin-EGFP group (35%, 30%, 25% and 1.60±0. 43,1.33± 0. 30,1.03±0.36) were significantly less than those at rAAV2-EGFP control group (80% ,75% ,85% and 2.43±0.53,2.43±0.29,2.66±0.45) and PBS control group (85% ,90% ,90% and 2.36±0.53,2.64± 0.57,2.53±0.52) at one 1, 2 and 3 ,weeks after treatment (all P<0.05). The expression of VEGF at ectopic lesion in rAAV2-endostatin-EGFP group at 3 weeks was significantly less than those at 1 and 2 weeks after treatment (P<0.05). (6) The level of estradial and progesterone in serum of nude mice of rAAV2-endostatin-EGFP group [ E_(2)> : (48±7 ) pmol/L, P: (61±8 ) nmol/L ] did not reach statistical difference when compared with those at rAAV2-EGFP control group [ E_(2): (50±9) pmol/L, P: (60±10) nmol/L] and PBS control group [E_(2):(48±7)pmol/L,P: (58±10)nmol/L,P>0.05]. Conclusions The recombinant adeno-asseciated virus carrying human endostatin gene therapy could inhibit angiogenesis at endometriotic lesions and not influence steroid level. The antiangiogenic gene therapy might become a novel option for endometriosis.
