In this paper,we focus on how to planning and implementing CRM system in hospital,and address this topic in three main sections.Firstly, The comprehending and urgent need of hospital leaders and managers about CRM are the most important.Secondly,before implementing CRM,the status of information management in hospital and characteristic of relationship between customers(or patients) and hospital should be sufficiently understood.Thirdly,which kind of CRM,and how much investment what you need should be analyzed.A general principle is put forward,that is "clear aim,macro planning,(uniform) disposal and stepping into implementing".

Background The measurement of the extraocular muscle is critical for the diagnosis of extraocular muscle diseases,but conventional medical imaging techniques present some shortcomings because of the contact pattern.The anterior segment optical coherence tomography (OCT) is thought to be an in vivo noninvasive optical diagnostic imaging method.Objective This clinical study attempted to seek an available approach to the evaluation of the anatomic structure of human horizontal rectus insertion with Visante OCT.Methods One hundred and fourteen eyes of 58 subjects were included in this study and were divided into the low refractive power group (≤-3.00 D) with 43 eyes,moderate refractive power group(＞-3.00 D-≤-6.00 D) with 49 eyes and high refractive power group(＞-6.00 D) with 22 eyes.The horizontal rectus insertion distance to the scleral spur and its thickness were measured by Visante OCT.The correlation of the refractive power with the rectus insertion distance or thickness was analyzed.Written informed consent was obtained from each subject before medial assessment.Results The average distance from the scleral spur to the lateral and medial rectus insertion were (5.23±0.50)mm and (3.81±0.46)mm respectively.The average thickness of the lateral and medial rectus insertions were (0.39±0.06)mm and (0.39±0.06)mm respectively,showing no significant differences in comparison with those of ultrasound biomicroscopy (P=0.338,P=0.759).The lateral and medial rectus insertion distances were (5.25±0.45)mm and (3.74±0.53)mm in the low refractive power the group,(5.22±0.60)mm and (3.81±0.42)mm in the moderate group and (5.20±0.35)mm and (3.90±0.42)mm in the high refractive power group,presenting inconsiderable difference among these three groups(lateral rectus: χ2=0.054,P=0.974;medial rectus: F=0.508,P=0.604).The thickness of the lateral and medial rectus insertions were (0.41±0.06)mm and (0.40±0.06)mm in the low refractive power group,(0.40±0.07)mm and (0.37±0.07)mm in the moderate refractive power group,(0.36±0.05)mm and (0.39±0.05)mm in the high refractive power group with a significant difference among lateral rectus (F=4.922,P=0.009) but not medial rectus (F=2.152,P=0.125).The lateral rectus insertions thickness in the high refractive power group was thinner than that in low refractive power group (P＜0.05).A positive correlation was found between refractive power and the thickness of lateral or medial rectus insertions (r=0.284,P＜0.01).Conclusion Visante OCT is a uscful way in measuring the distance and thickness of the extraocular muscles.Lateral rectus insertions thickness tends to be thinner with the worsening of myopia,which is obvious in high myopia.

We examined diseases occurring farmed Whitmania pigra(L.) in Hebei province in the aspect of situation of disease,clinical symptoms and pathological changes.In addition,the molecular identification were conducted to representative strain,the 16S rRNA gene was sequenced and compared with that of related strains,molecular phylogenetic tree was constructed.The results showed that the disease was infected by Aeromonas hydrophila.Pure cultures of 10 strains have the same serotype.Selected representative strain was proved to be the corresponding primitive causal agent of the disease by artificial infection experiment to healthy Whitmania pigra(L.).Antibiotic sensitivity of the isolates to used thirty-seven antimicrobial agents showed that the tested strains were high sensitive to cefotaxime et al.,were sensitive to streptomycin et al.,were resistant to oxacillin et al.

Objective: To investigate the effect of carboxymethylchitosan on autocrine growth factor and morphology of fibroblasts cultured in vitro, so as to discuss the possible mechanism by which carboxymethylchitosan alleviates overheating and prevents adhesion in wound healing. Methods: Fibroblasts were cultured in vitro. Fibroblasts of passage 4-6 were treated with different concentrations of carboxymethylchitosan (0.01,0.1,1.0 and 10 mg/ml) for 4 days or with 0.1 mg/ml carboxymethylchitosan for 1, 2, 3, 4, 5, and 6 days. The levels of autocrine transforming growth factor-β1 (TGF-β 1) and epidermal growth factor (EGF) of fibroblasts were determined by ELISA and radioimmunoassay. The fibroblastic morphology was detected by transmission electron microscopy (TEM) and microscope after fibroblasts were treated with different strategies. Results: Carboxymethylchitosan (≥ 0.1 mg/ml) inhibited autocrine TGF-β1 of fibroblast in a time- and concentration dependent manner (P< 0.05). However, Carboxymethylchitosan had no obvious influence on the secretion of EGF(P>0.05). Carboxymethylchitosan (≥ 0.1 mg/ml) also inhibited the proliferation of fibroblasts and caused their ultrastructural changes. Conclusion: Carboxymethylchitosan (≥0.1 mg/ml) can inhibit fibroblasts proliferation and reduce tissue adhesion, possibly through altering fibroblast ultrastructure and selectively inhibiting secretion of TGF-β1.

Objective: To prepare and evaluate the effectiveness of chitosan-carboxymethylcellulose membrane in preventing postoperative intestinal adhesion. Methods: Chitosan-carboxymethylcellulose membrane was prepared with 1:1 ratio of chitosan and carboxymethylcellulose. Glutaraldehyde and ammonium aluminium sulfate were used for cross-linkage, glycerin for enhancing plasticity; and then the product was dried. The membrane was observed with scanning electron microscopy (SEM) and its tensile strength and breaking elongation were measured. Forty-eight SD rats with ileum injury were randomly divided into A, B and C groups (n=16). During operation, the injury in group A was treated with chitosan-carboxymethylcellulose membrane, in group B with chitosan membrane, and in group C without treatment (control group). The adhesion was observed on the 14th postoperative day. Results: The tensile strength of chitosan-carboxymethylcellulose membrane was 20 MPa and the breaking elongation was 65%. SEM showed that the morphology of the membrane had crossed fibroid structures and irregular pores. The severity of adhesion in group A and B was significantly lower than that in group C (P<0.01). Milder inflammatory changes and less fibrous proliferation were found in group A and B compared with those in group C. Epithelia rehabilitated better in group A than in group B, and the proliferation of fibroblast was not significant under electron microscope. In group C, epithelia rehabilitated slowly and fibroblasts excreted collagen actively. Conclusion: Chitosan-carboxymethylcellulose membrane is feasible for suturing during operation and is effective in reducing intestinal adhesion and it is superior to chitosan membrane.

The infrastructure of Liberia has been destroyed due to the prolonged civil war.In this situation,it's critical for the Medical Contingent to have a good self-communication to carry out medical support for the United Nations Mission in Liberia.The communication instruments,their management and maintenance are introduced in this paper.The communication support for large-scale movement is emphasized on.The methods for using effectively the restricted Internet connection are discussed in detail.To cope with the problems of poor communication between the Medical Contingent and homeland,an Internet connection system is put forward which is based on VSAT(very small aperture terminal)hardware platform and subscription of international Internet connection.The system is believed to be reliable,economical,flexible and convenient.

ATP-sensitive potassium channels (KATP channels) play important roles in various tissues under physiological and pathophysiological conditions by coupling cell metabolic status to electrical activity. The KATP channe l is a tetrameric complex of inwardly rectified potassium (Kir) and ATP binding protein (ABP). The Kir subunits form the channel pore, whereas ABP is required for activation and regulation. Both Kir and ABP are divided into different subu nits and the various Kir and ABP subunits “mix and match” to form KATP c hannels with different pharmacological and nucleotide sensitivities. This revie w focuses on the molecular structure, physiological roles, pathophysiological an d pharmacological properties of KATP channels in different tissues.

EPA exists wildly in artery vascular endothelium and could be activated by endogenously activated substances and regulate the vascular tone. The endothelium-dependent vascular relaxation mediated by EPA has been used for almost 20 years as an indicator of endothelium dysfunction. In many cardio-vascular diseases, EPA function was down-regulated. The pharmacological profiles of EPA could be characterized by muscarinic properties, as well as non-muscarinic properties in selectivity for agonists and antagonists and in binding characteristics. The endogenous ligand, receptor type and molecular pharmacological characteristics of EPA are waiting to be investigated.

A case of methamphetamine-related cerebral infarction was reported and the relevant databases of CBMdisc and Medline were searched.Among 14 cases of ischemic stroke , the ratio of male:female was 9∶5 and the age range 19-45 years.There were anterior circulation lesions ( n=13,92.8%) and 10 of them (71.3%) had cerebral vascular occlusion or stenosis.And the predominant manifestation was hemiplegia (85.7%);among 34 cases of hemorrhagic stroke ,the ratio of male: female was 12∶5 and the age range 16-60 years.And 28 cases (82%) were≤45 years.Cerebral hemorrhage was the most common (85%).The major manifestations were headache ( n =26, 76%) and disturbance of consciousness (n=21,62%).The methamphetamine-related stroke occurs frequently in young males.And ischemic stroke tends to involve anterior circulation and cause hemiplegia.Yet hemorrhagic stroke has extensive attack sites and headache and disturbance of consciousness are quite common.
