Objective:To investigate the regulation of proliferation and differentiation of bone marrow mesenchymal stem cells(BM-SCs)by CKIP-1 in vitro.Methods:BMSCs from CKIP-1 nock out(KO)and wild type(WT)C57 mice were isolated and cultured u-sing adherence method in vitro.BMSCs of the 3rd passage were induced to osteogenic and adipgenic differentiation.Cell proliferation was examined by MTT assay.Cell surface markers were tested by FCM.The osteogenic and adipogenic differentiation was studied by alkaline phosphatase (ALP)staining,alizarin red staining and oil red O staining.Results:The proliferation and cell marke expression of the 2 groups were similar.ALP staining of KO group was strong than that of WT group after osteogenic induction.Alizarin red stai-ning showed that there were more mineralized nodules in BMSCs of KO group than in those of WT group.Oil red O staining of KO mice BMSCs was stronger than that of WT.Conclusion:CKIP-1 deficiency can enhance the osteogenic and adipogenic differentiation without influence on the proliferation of BMSCs.

Objective:To evaluate the effects of maxillomandibular advancement and contrarotation in the treatment of severe com-plicated multilevel obstructive sleep apnea/hypopnea syndrome (OSAHS).Methods:1 2 patients (all males,aged 26 to 56 years) with severe complicated multilevel OSAHS were treated by orthognathic surgery methods of maxillomandibular advancement and cont-rarotation and followed up for 6 -1 2 months.Results:After surgery the symptoms of all patients,such as snoring,waking up be-cause of stoke and streaming with sweat,disappeared or were ameliorated remarkably.The AHI index declined from 51 -70 before operation to 0 -3 after operation.While sleeping,their blood oxygen saturation augmented from 30% -70.1 % presurgically to 93%-99% postsurgically,and their average blood oxygen saturation increased from 60% -72% presurgically to 95% -99% postsurgi-cally in all 1 2 patients.Conclusion:Orthognathic surgery method of maxillomandibular advancement and contrarotation is effective in the treatment of severe complicated multilevel OSAHS.

Background and purpose: Uveal melanoma (UM) is the most common primary intraocular malignancy in adult. Due to a high tendency for early metastasis the treatment of UM is very difficult. This study aimed to explore an effective approach for the treatment of patients with UM, we designed a strategy that combined HtrA2 gene therapy and radiation therapy. Methods:pIRES-Egr1-Omi/HtrA2 (pEgr1-HtrA2) recombinant plasmids were constructed and transfected into human UM cells (OCM-1) in vitro. The transfected cells were exposed to irradiation. HtrA2 mRNA and protein levels were detected by qRT-PCR and Western blot respectively. Assays that evaluated the apoptosis inducibility caused by HtrA2 gene therapy combined with radiation was performed by lfow cytometry. Followingly, the effects of HtrA2 overexpression on the in vitro radiosensitivity of uveal melanoma cells were investigated by clonogenic formation assay. The in vivo effects of HtrA2 gene therapy combined with radiation therapy were evaluated in different groups. Results:The recombinant plasmids could be successfully transferred into OCM-1 cells and transfection of pEgr1-HtrA2 plasmids combined with radiotherapy caused dramatically elevation of HtrA2 compared with non-irradiation cells in mRNA and protein levels, which was associated with increased apoptosis.Furthermore, we observed that the transfection of pEgr1-HtrA2 could significantly enhance radiosensitivity of OCM-1 cell in vitro. In mice bearing xenograft tumors, pEgr1-HtrA2 combined with radiation therapy signiifcantly inhibited tumor growth compared with the other treatment groups (P<0.05). Conclusion:Our ifndings indicate that radiation-inducible gene therapy may have potential to be a more effective and speciifc therapy for uveal melanoma because the therapeutic gene can be spatially or temporally controlled by exogenous radiation.

Objective To study the state and trends of Kesan disease in Henan province from 2004 to 2009. Methods Surveillance sites were selected: Guxian village of Luoning country from 2004 - 2007, Zuyang town of Lingbao city in 2008, and Shahe village of Lushi country in 2009. All residents of surveillance sites were examined by clinical and electrocardiogram, and suspected patients were inspected by chest X-ray to measure ardiothoracic ratio. Hair and wheat flour samples were collected and selenium levels were detected with hydride generation atomic fluorescence spectrometry. Results From 2004 to 2009, a total of 4034 people were examined.The numbers of chronic and latent KSD patients were 21 and 75 cases,respectively, and the incidence rates were 0.52%(21/4034) and 1.86%(75/4034), respectively . The number of abnormal electrocardiogram was 751 cases, and the incidence rate was 18.62%. The highest proportion of abnormal electrocardiogram was ST-T changes,accounting for 24.63%(185/751), followed by high-voltage, accounting for 18.11%(136/751), and left ventricular accounting for 13.85% (104/751). Sixty-one grain samples were collected and the wheat flour selenium level was averaged 0.034 mg/kg. Thirty hair samples were collected and the selenium median was 0.285 mg/kg. Conclusions The state of Keshan disease is in a steady state in Henna province, but higher rates of abnormal electrocardiogram is a serious problem and should be studied and prevented.

Objective To understand Kaschin-Beck disease(KBD) status in Henan Province and provide the basis for the further prevention and treatment of KBD. Methods Children aged 7 to 12 in 3 villages(Yaodian, Miaowa and Zhuyang) with the same environment such as topography, physiognomy,production mode and living habits in Shan County and Lingbao City were selected to undertake KBD clinical examination in 2008, X-ray examination of right hand and child hair samples and food samples were collected to determine the content of selenium. Selenium was determined using 2,3-Diaminonaphthalene method. Adults who were 16 years or older in 5 counties(Luoning, Lingbao, Mianchi, Shah and Lushi) were selected and examined for KBD. Results One hundred and ninty children aged 7 to 12 were clinically examined and clinical KBD were found, whereas 3 children were diagnosed as KBD by X-ray examination, the positive rate was 1.58% (3/190). All 20 521 adults were clinically examined and KBD prevelance rate was 6.10%(1251/20 521), including degree Ⅰ (3.97%,814/20 521), degree Ⅱ (1.77%, 364/20 521 ), degree Ⅲ (0.36%, 73/20 521). The average selenium contents in hair and food samples were (0.319±0.128)mg/kg and (0.031±0.009)mg/kg, respectively. Conclusions Child KBD in Henan Province is under control or almost under control, whereas the prevalence of adult KBD was relatively serious, which suggested that secondary prevention with the objective of clinically treating KBD patients should be strengthened.

OBJECTIVE: To systematically review the efficacy and safety of taxane, cisplatin, and fluorouracil (Tax-PF) as induction chemotherapy for advanced head and neck cancer. METHOD: Literature about the efficacy and safety of Taxane-cisplatin-fluorouracil as induction chemotherapy for advanced head and neck cancer was retrieved from digital databases of PubMed, Embase, SpringerLink, MEDLINE and the Cochrane Library before February 2015. Data extraction and quality assessment of included studies were conducted by two reviewers independently. Stata 13.0 was then used to perform Meta-analysis. RESULT: A total 7 randomized controlled trials involving 2,702 were included. The 3-year OS rate [HR = 1.14, 95% CI (1.03, 1.25), P < 0.01], 3-year PFS rate [HR = 1.24, 95% CI (1.08, 1.43), P < 0.01], 5-year OS rate [HR = 1.30, 95% CI (1.09, 1. 55), P < 0. 01], 5-year PFS rate [HR = 1.39, 95% CI (1.14, 1.70), P < 0.01] and ORR to chemotherapy [OR = 1.66, 95% CI (1.35, 2.05), P < 0.01] of the patients in the Tax-PF group were statistically superior to those in the PF group. In terms of toxicities, the incidence of febrile neutropenia [OR = 2.36, 95% CI (1.62, 3.46), P < 0.01], alopecia [OR = 8.22, 95% CI (3.99, 16.92), P < 0.01], diarrhea [OR = 1.57, 95% CI (1.05, 2.36), P< 0.05] and leucopenia [OR = 2.79, 95% CI (1.86, 4.21), P < 0.01] was higher in the Tax-PF group than that in the PF group. CONCLUSION The Tax-PF induction chemotherapy improved PFS and OS, and the ORR was better as compared to PF-based therapy regimens at the cost of a higher incidence of adverse events.
