2.Obstructive sleep apnea as an independent risk factor for stroke: possible mechanislms
International Journal of Cerebrovascular Diseases 2011;19(12):911-915
Obstructive sleep apnea (OSA),the most common type of sleep disordered breathing was closely associated with the occurrence of ischemic stroke.It has been demonstrated that OSA is an independent risk factor for ischemic stroke.Its pathogenic mechanism includes atherosclerosis,coagulation abnormalities and cerebral hemodynamic changes caused by long-term periodic hypoxia hypoxemia and hypercapnia.The prognosis of ischemic stroke patients with OSA is poor.Therefore,it needs to be treated early to avoid further damage to brain tissue and reduce the mortality.

Chinese Journal of AIDS & STD 2006;0(02):-
Objective To explore the effectiveness of short-term integrated intervention to reduce discrimination against people living with HIV/AIDS(PLWHA)among medical students.Methods A quasi-experimental survey was conducted.Two medical schools in Beijing,one as intervention group and the other as control group were selected by convenience sampling,from which 123 undergraduate students or interns of medical and nursing specialties were recruited,62 in the intervention group and 61 in the control group.The intervention group was provided with 13 hour long antidiscrimination intervention by increasing HIV/AIDS related knowledge,sympathy and skill in dealing with people living with HIV/AIDS,while the control group was deprived of any intervention.The attitude of the students in the 2 groups were assessed by questionnaire survey in 5 time points after the intervention.Results Compared with the control group,at 4 time points after the intervention students in the intervention group had less discrimination against PLWHA in general;and significantly less discrimination in dealing with them as patients(P
4.tRNA Nuclear-cytoplasmic Dynamics and Cell Fate
Progress in Biochemistry and Biophysics 2006;0(03):-
The robust nuclear-cytoplasmic transport is vital for eukaryotes'life cycle.Not only proteins and RNAs are transferred to their destination by this system, the important cellular activities such as mitosis are also regulated by the transport pathways via adjusting the local concentrations of some critical cargoes.tRNA is one of the most important biomacromolecules in the cell, synthesized in nucleus, and taking part in protein synthesis in cytoplasm.It is a long-held belief that tRNA functions only as a key player in protein synthesis, and tRNA nuclear-cytoplasmic transport is a unidirectional movement from nucleus to cytoplasm.However, the recent discoveries are overturning the traditional opinions.Nuclear-born tRNA can be exported out of nucleus, while cytoplasmic-residing tRNA can also be retrogradely transport into nucleus.The new concept tRNA nuclear-cytoplasmic dynamics was coined in 2008 to describe the tRNA communication between nucleus and cytoplasm, which was found able to regulate protein synthesis and cell cycle in S.cerevisiae.The latest results in this field are going to change the landscape of eukaryotic tRNA biology.

Objective To observe the effect of external fixator combined with limited internal fixation in the treatment of complex ankle fractures.Methods According to the digital table,65 patients with complex ankle fracture were randomly divided into treatment group(33 cases) and control group(32 cases).The treatment group was treated with external fixator combined with limited internal fixation,the control group was treated with internal fixation.All patients were followed up for 5 to 20 months.The curative effect and incidence rate of complication of the two groups were observed.Results The excellent rate of the treatment group was 84.85%,which was higher than 62.50% of the control group,the difference was statistically significant(x2=4.20,P<0.05).The incidence rate of complications in the treatment group was 3.03%,which was lower than 18.75% of the control group,the difference was statistically significant(x2=4.18,P<0.05).Conclusion External fixator combined with limited internal fixation can effectively treat complex ankle fractures,the method can not only make patients satisfied with the reduction effect,but also the internal fixation complications such as infection are minimized,the clinical value is extremely high,it is worthy of wide application.
6.The expression of focal adhesion kinase and Ki67 in invasive breast ductal carcinoma and their clinical significance
Chinese Journal of Immunology 1985;0(06):-
Objective:To investigate the expression of focal adhesion kinase(FAK) and Ki67 in the invasive breast ductal carcinoma tissues, seeking their relationship with tumor invasion and metastasis and to study the mechanisms for cell signaling transduction mediated by FAK in the carcinogenesis and progress of breast carcinoma.Methods:Tissues were obtained from 88 patients with invasive breast ductal carcinoma and 25 with breast ductal epithelial benign proliferative disease. The expression of FAK and Ki67 was examined by immunohistochemical technique(streptavidin peroxidase conjugate method, SP).Results:In 88 cases of invasive breast ductal carcinoma, the positive incidences of FAK was 68.2%(60/88), and the Ki67 proliferation index was 29.6%?22.9%, which distinguished apparently to those of the control group(P0.05). In breast carcinoma tissues, the expression of FAK was positively related to Ki67 proliferation index(P
7.Effects of Nitric Oxide on Growth and Metastasis of Tumor
Chinese Journal of Bases and Clinics in General Surgery 2003;0(06):-
Objective To study the effects of nitric oxide (NO) on the growth and metastasis of tumor.Methods The literatures of recent years were reviewed.Results NO had double effects on the growth and metastasis of tumor. NO promoted the growth and metastasis by regulating the expression of tumor proliferation gene and inducing tumor angiogenesis. On the other hand, NO had antitumor effects by interfering with the metabolism of tumor cells, inducing the damage of DNA, forming high toxic free radical, inducing apoptosis of tumor cells and mediating the antitumor action of endothelial cells and macrophages.Conclusion Selective blockage or induction of synthesis of NO may be a new way for tumor therapy.
8.Clinical study on intratympanic dexamethasone injection in treatment of sudden sensorineural hearing loss
Chinese Journal of Postgraduates of Medicine 2010;33(15):17-19
Objective To observe the clinical efficacy of intratympanic dexamethasone injection for patients with sudden sensorineural hearing loss (SSNHL). Methods Forty-four SSNHL cases (44 ears) which failed to respond to regular treatments were divided into two groups. The intratympanic injection group (24 eases) were injected dexamethasone 2.5 mg to the tympanic cavity every two days,4 times in all. The control group (20 eases) were treated with B1,B12 and triphosaden. Pure tone average (PTA) was tested before and 3 days after treatment. Results The total effective rate of intratympanic injection group was higher than that of control group [37.5%(9/24) vs 10.0%(2/20)] (P < 0.05). In intratympanic injection group, PTA of post-injection was significantly lower than the pre-injection[ (52.75±20.14) dB vs (70.26±20.76) dB ] (P < 0.05). PTA of post-injection in intratympanic injection group was significantly better than that in control group[(52.75±20.14) dB vs (63.55±19.36) dB](P< 0.05). Conclusion Intratympanic dexamethasone injection can be applied to SSNHL patients who failed to respond to systemic corticosteroid treatment and it can avoid the side effects brought on by high dose systemic corticosteroid treatment.

Objective:To observe the effectiveness and security of piperacillin sodium/sulbactam sodium in the treatment of bacte-rial infections and perform the pharmacoeconomics evaluation. Methods: Totally 126 patients with hand trauma bacterial infections were divided into the control group and the treatment group. The control group was given piperacillin sodium/tazobactam sodium 2. 5g, ivd, bid, while the treatment group was treated with piperacillin sodium/sulbactam sodium 1. 25g, ivd, bid. After 14-day treatment, the clinical therapeutic effect and adverse reactions of the two groups were observed, and the cost-minimization analysis was carried out. Results:The effective rate of the treatment group was 93. 65%while that of the control group was 92. 06%(P>0. 05). The bac-terial clearance rate of the treatment group was 96. 83%while that of the control group was 95. 24% (P>0. 05). The incidence of ad-verse reactions of the treatment group was 4. 76% (3/63) while that of the control group was 9. 52%(P>0. 05). The cost-effective-ness of piperacillin/sulbactam was significantly lower than that of the control group (P<0. 05). Conclusion: The effectiveness and safety of the two groups show no obvious differences in the treatment of hand trauma bacterial infections, and both have good antibacte-rial effect with low incidence of adverse reactions. For the better economic benefits, piperacillin /sulbactam is worthy of promoted ap-plication.
