The total rate had been dropped year by year.The major sites of the infection were the(upper)(respiratory) tract(34.82%),the gastrointestinal tract(20.45%) and the urinary system(18.53%).The(infection) rate in ladies patient area(3.83%) was significantly higher than that of gentlemen patient area(3.07%)(P

AIM: To investigate the changes of serum angiogenic factors including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor ( bFGF) in Mongolia patients with diabetic retinopathy ( DR) and to explore their roles in the progress of DR.
METHODS: Eighty - three patients with diabetes were divided into three groups according to the retinopathy, no DR group ( NDR, 25 cases), background DR ( NPDR, 31 cases) and proliferative DR group (PDR, 27 cases), and 36 age - matched healthy people ( control group) were selected. Serum concentrations of VEGF and bFGF were measured using ELISA method.
RESULTS: In Mongolia patients with diabetes, the serum concentrations of VEGF and bFGF were higher than those in control group; the serum concentrations of VEGF and bFGF in PDR group was higher than those of NDR and NPDR group (P< 0. 05); the concentrations of VEGF and bFGF in NPDR group was higher than that of NDR group (P<0. 05).
CONCLUSION: High level of VEGF and bFGF may be the important pathogenic factors for DR in Mongolia patients.

Dry eye is one of the most frequently ocular surface diseases. Recent researches found that many reasons caused decrease of ocular surface damage and the quality of tears , such as the change of ocular surface, immuno-inflammatory responses, apoptosis and the reduction of sex hormone. It is reported that the decline of ovarian function and hormone level in postmenopausal women which leads to abnormal structure and function of tear film is more likely to develop dry eye. In this paper, the ocular surface, pathogenesis and progresses of treatment on postmenopausal women with dry eye are reviewed.

Objective To understand the attitude of health workers towards people living with HIV and AIDS(PLWHA) and AIDS knowledge and desire for related training among them in selected hospitals in Beijing.Method Convenience sampling was used to select health workers from 32 hospitals of different levels in 4 districts within Beijing.Anonymous self-administrated questionnaires were used to collect the information regarding AIDS knowledge and desire for relevant training.Results A total of 1 292 health workers completed the questionnaire.They demonstrated a moderate level of general AIDS knowledge,but a low level of knowledge related to AIDS diagnosis and therapy.Of them 39.7% had received specialized AIDS training and 96% had strongly desire for such specialized training.Most health workers sympathized with PLWHA and understood their situation,while some of them were afraid of PLWHA and wanted to have minimal contact with PLWHA.91.3% of the health workers expressed that PLWHA should have the same rights to medical services.At the same time,49.2% of the health workers stated that they would not like to work in hospitals or departments which accepted PLWHA.80% of the health workers expressed concern over acquiring HIV infection in the workplace.52.7% of them thought that they had a risk of becoming infected in the workplace.Conclusion The level of AIDS knowledge among health workers in Beijing needs to be improved.Specialized training to enhance and develop health workers knowledge of prevention,diagnosis and treatment of AIDS is required.Most of the health workers do not discriminate against PLWHA,but they express concern over infection in the workplace.

Objective To study effects of hFRNK gene on phosphorylated p190RhoGAP expression and RhoA activation by mediated adenoviral vector in colorectal carcinoma cell Colo320WT stimulated with extrinsic gastrin17 in vitro.Methods AdEasyTMsystem was used to construct pAdhFRNK expressing human FRNK gene by recombination in E.coli.BJ5283.pCR3.1/GR plasmid expressing gastrin receptor CCK-2 was transfected into colonic carcinoma cell line Colo320 cells by LipofectamineTM2000 and expression stably CCK-2R clones was selected by G418(500 ?g/mL).The expression levels of gastrin receptor of Colo320 cells and the transfected cells Colo320WT were assayed by RT-PCR.Colo320WT cells were treated by 10～8 mol/L Gastrin17 for 0h and 12 h;and after Colo320WT cells were infected by pAdhFRNK(MOI:100)for 2 d,the cells were treated by Gastrin17 for 12 h again.The expression levels of phosphorylated p190RhoGAP of Colo320WT cells were assayed by immuniprecipation and western blot.RhoA activation was assayed by pull-down.using GST-Rhotekin-RBD followed by RhoA blotting.Results When 10～8 mol/L Gastrin17 stimulated Colo320WT cells for 12 h,the expression levels of phosphorylated p190RhoGAP increased apparently and RhoA activation diminished.When pAdhFRNK infected Colo320WT cells for 2 d and 10～8 mol/L Gastrin17 treated the cells for 12 h,the expression levels of phosphorylated p190RhoGAP decreased apparently and RhoA activity was elevated.Conclusion hFRNK can inhibit expression of phosphorylated p190RhoGAP and enhanced RhoA activity in the cells stimulated with Gastrin17,and its mechanism is probably that hFRNK can block FAK phosphorylation and FAK pathway.

To investigate the changes in CAP and CM recorded from the cochlear round window when glutamate solution in different concentrations(10mmol/L, 5mmol/L, 1mmol/L) was instilled into whole cochlea perilymph. The results demonstrated that there was a dependent correlation between CAP threshold shift and glutamate concentration. CAP threshold shift and amplitude could be markedly influenced by glutamate instillation. However, amplitude of CM was not obviously affected, and the I/O function of CM amplitude always maintained a nonlinear characteristic. The results suggest that glutamate has selective effects between inner hair cells and outer hair cells. High concentration glutamate might cause an increase in intracellular calcium, even as high as to induce toxicity. It could be induced by glutamate when it acts on IHC′s presynaptic autoreceptor in positive feedback manner, or on the afferent neurons, so that the synapsis is directly damaged by glutamate concentration overload in synaptic cleft.
