Objective: To investigate the changes in common chemical signal molecules of neuroendocrine-immune (NEI) network and intervention of Tongxinluo (TXL, ultramicro-pulverization) of rats under hypoxia qi-asthenia condition. Methods: Forty-five male Wistar rats were randomly assigned to the following groups: control group, qi-asthenia model group and TXL group (n=15). The rats in the former 2 groups were gavaged with CMC-Na (10 ml/ kg) once daily; those in the TXL group were gavaged with TXL (ultramicrot-pulverization) suspended in CMC-Na (10 ml/kg) once daily; After gavage, animals in the qi-asthenia model group and TXL group were placed in a cabin with normal pressure hypoxia (7 h daily, 6 d weekly for 5 weeks). At the end of the experiment, the biological characters of rats were observed and arterial blood gas was analyzed. The serum contents of serotonin (5-HT), norepinephrine (NE), epinephrine (E), dopamine (DA) and IFN-γ and TRH level in the hypothalamus were examined by enzyme linked immunosorbent assay (ELISA); the serum contents of corticosterone (Cort), T3,T4,IL-1β,TNF-α, and corticotropin release hormone(CRH) in the hypothalamus, and adrenocorticotropic hormone/thyroid stimulating hormone(ACTH/TSH) in the hypophysis cerebri were examined using radio-immunity method. Results: Compared with control group, the biological character scores of rats in the qi-asthenia model group were significantly bigher(P

Objective:To study the radiation-sensitizing effects of nimotuzumab and X-ray radiotherapy on human esophageal carcino-ma KYSE450 cells. Methods:Human esophageal carcinoma cells KYSE450 were treated with nimotuzumab, irradiation, and the combi-nation of both. Cell growth inhibition was evaluated by MTT assay, and cell cycle distribution and apoptosis were analyzed by flow cy-tometry assay. Cell radiosensitivity was tested by clonogenic assay, and the survival curve was fitted using multi-target single-hit mod-el. The combination and accelerated radiation groups were tested by microarray technology, and the differentially expressed genes were screened among the two groups. Results:The growth of KYSE450 cells was inhibited in three groups, namely, the group treated with nimotuzumab, the group treated with irradiation, and the group treated with both. The group treated with both nimotuzumab and irradiation resulted in the highest inhibition rate (35.25%±5.62%) compared with that of the nimotuzumab (16.12%±8.73%) and ir-radiation groups (27.64%± 6.66%) (F=10.953, P<0.001). The highest rates of G2 phase arrest and cell apoptosis were observed in the group treated with the combination of nimotuzumab (29.37%±7.29%) (F=17.299, P<0.001) and irradiation (18.80%±2.03%) (F=85.691, P<0.001). Multi-target single-hit model showed that the values of SF2, Do, and Dq in the group with both treatments were smaller than those of the irradiation group with sensitization enhancement ratio of 1.63, which confirmed the radiosensitization effect of ni-motuzumab on KYSE450 cells. Microarray technology analysis found that nimotuzumab can enhance the radiosensitivity of esophageal squamous cell carcinoma by cutting the genes of EGF/PDGF signaling pathways. Conclusion:This experiment shows that nimotuzumab can effectively inhibit the growth of human esophageal cancer cell KYSE450. Nimotuzumab can also promote apoptosis and G2 phase arrest when combined with X-ray radiotherapy, thereby enhancing the radiosensitivity of KYSE450 cells. This effect is associated with cutting the genes of EGFR signaling pathways.

Objective To observe the temporomandibular joint spaces changes after the plastic surgery of combined zygoma with mandibular angel.Methods We randomly selected 59 patients with prominent zygoma and mandibular angle,screening periodontal disease,TMJ pain and partial jaw.Bilateral zygomatic arch coarctation,jaw edge of the mandibular angle ostectomy and the mandibular body outer panel split were used.All patients accepted CT scan and three-dimensional reconstruction before operation,10 days after operation and 6 months after operation,and then image analysis softwares were used to measure the line distance of corresponding angle (0°,60°,120°,and 180°)at the TMJ sagittal plane.The 0° (EE 'pitch) and 60° (AA'pitch) represented for pre-space,the 60° and 120° (PP'pitch) was upper-space,the 120° and 180° (SS'pitch) was posterior-space.Results 0° and 60° had the same change trend,which slightly increased at 10 days after operation.The difference before operation and 10 days,6 months after operation were not statistically significant (P ＞ 0.05);120° and 180° had the same change trend,which increased at 10 days after operation.The difference between before operation and 10 days after operation was statistically significant (P ＜ 0.05),but the difference between before operation and 6 months after operation was not statistically significant (P＞ 0.05).Conclusions In the short term after plastic surgery of zygoma combined with mandibular angel,the TMJ upper and posterior spaces are changed,and the interspace reduced.This may indicate that the TMJ has compensatory ability,and short-term changes can return to normal.

AIM: To observe the effect of exogenous androgen responsive element decoy on the promoter of prostate specific antigen (PSA) and the growth of LNCaP cells for searching the possibility of gene therapy for prostate cancer. METHODS: Firstly, pGL3 - PSA luciferase expression vector containing 640bp - promoter fragment of PSA gene was constructed. Then, a 23 -mer phosphorothioated ARE decoy based on the deduced ARE sequence at the promoter region of PSA gene was synthesized. pGL3 - PSA and ARE decoy DNA were cotransfected into PC3 - M cell by lipofectamineTM 2000. Through detecting the activity of luciferase, the effect of ARE decoy on the promoter of PSA was studied. Then the ARE decoy DNA was transfected into LNCaP cells. The effect of decoy DNA on the proliferation of LNCaP cells was examined by using MTT assay. The effects of apoptosis were detected by phase contrast microscopy, DNA agrose gel electrophoresis and flow cytometry. Meanwhile, the nuclear extract was prepared from LNCaP cells and DNA - protein interactions were examined by electrophoretic mobility shift assay (EMSA). RESULTS: The reporter assay showed that the aetivity of luciferase was significantly reduced in the ARE decoy - transfected cells, bnt not in the cells transfected with the control decoy. EMSA demonstrated specific binding of the ARE decoy to androgen receptor. The growth of LNCaP was remarkably inhibited and apoptotic morphological changes as well as DNA fragmentation were observed in the ARE decoy- transfected cells. The rate of apoptosis was 22.4% detected by FCM. CONCLUSION: The ARE decoy is capable of inhibiting the promoter of PSA gene and inducing the apoptosis in prostate cancer cells. It may become a potential therapeutic tool for prostate cancers.

Objective To study the effects of Cad-Ⅱgene on osteogenic differentiation of human mesenchymal stem cells in vitro. Methods The human marrow mesenchymal stem cells (hBMSCs) were isolated and cultured in vitro before they were divided into 2 groups. In the transfeetion group, the hBMSCs were transfeeted with Cad- Ⅱgene;in the simple osteogenic inducement group, they were cultured in the condition medium. Then the expressions of Cad- Ⅱ protein were determined and the alkaline phosphatase (ALP) activities and the expressions of ostcocalein were measured at 3, 7, 14 and 21 days for comparison between the 2 groups. Results The ALP activity and positive expression of osteoealcin were regulated significantly higher in the transfeetion group than in the simple osteogenic inducement group at different times (P <0.05). The mineralized nodes began to appear at 14 days in the 2 groups and increased with time. Conclusion Cad-Ⅱgene transfeetion can promote differentiation of hBMSCs into the osteoblasts.
