40 rabbits are used to study the effects of phaco-emulsification and extracap-sular lens removal or; corneal endothelial cells and corneal thickness.With the specular microscope, the preoperative cell morphology, cell density and thickness of cornea are revealed. The endothelial cell counts decrease 16% (at central) and 14% (at the periphery) after the surgery with phaco-emulsification and 25% (central) and 22% (periphery) with extracapsular lens removal. Corneal thickness increases in both groups. Scanning electron microscopy shows some alterations in morphology of endothelial cell injury significantly different in the 2 groups. According to these results the causes of corneal thickness increasing and mechanism of endothelial cell injury are approached and a new procedure preventing the cell injury and decreasing cornea edema in both groups is designed.

Referring to relative documents,it reviews the developments on the relation between IIS and gastro-intestinal hormones(gastrin,gallbladder bile-syst contractin,active vessel intestinal peptide and article P),and sums up the relativity study on the relativity between different TCM types of IIS and gastro-intestinal hormones secretion level.

Dendritic cells (DCs)can capture HIV from the mucosal site and carry it to the draining lymph nodes to promote CD4 + T cell infection.DC-SIGN(CD209)plays a vital role during this process. Heroin,methamphetamine and cocaine are the most abused drugs used by drug abusers,which can increase the opportunities of HIV infection.Drugs acting on the corresponding receptors activate the downstream signaling pathway and regulate the expression of DC-SIGN on the surface of DCs,weakening the inhibited effects of immune cells on HIV and promoting HIV infection in many aspects.Given the multiplex effects of drugs on immune function,this article reviews the relationship between abused drugs,DCs and HIV infection,particularly in the signal pathway on immune modulation.

Objective To observe the therapeutic effect of Shenqi Fuzheng injection combined with EP chemotherapy in the treatment of non small cell lung cancer (NSCLC),and to improve the quality of life and side effects.Methods 60 cases of NSCLC were randomly divided into observation group and control group,30 cases in each group.The two groups were treated with EP,the observation group was treated with Shenqi Fuzheng injection for two courses.The life quality and adverse effects were observed.Results The quality of life of the two groups after treatment was compared,the difference was statistically significant (93.3% vs 70.0%,χ2 =2.83,P <0.05),the quality of life in the observation group was significantly higher than that in the control group.The white blood cell reduction,anemia and liver and kidney function damage between the two groups had statistically significant differences (P =0.011,0.025,0.016),the adverse reaction of the observation group was less than the control group.Conclusion Shenqi Fuzheng injection combined with EP regimen in the treatment of NSCLC can protect bone marrow hematopoietic function and improve the quality of life of patients with NSCLC chemotherapy.It can be used as one mean of Chinese and western treatment for patients with NSCLC in clinical application.

With the development of communication techniques,the satcom telemedicine system is being applied more and more widely. Satellite communication is a means of communication of the broadest transmission scope and the largest coverage.The establishment of the satcom medicine system has effectively solved such bottleneck problems as date transmission block and network interrupt,The present article reviews the development of the satcom telecommunication system at home and abroad,the composition and characteristics of telecommunication,the composition and function of the PLA VSAT satcom telemedicine system,and the trend of development.

Objective To evaluate the clinical value of rotational digital subtraction angiography(DSA).Methods The rotational DSA was performed 48 cases in 30 patients with PHILIPS V5000 digital imaging system.Among them,cerebral(n=8),carotid(n=2),limbs(n=7),hepatic(n=2),pulmonary(n=1),iliac(n=2),aortic(n=1),renal(n=2)and uterine(n=5)arteries were included.Results The origins,running,distributions,numbers and contours of diseased segments of arteries and pseudoaneurysm were clearly displayed in 28 of 30 patients with the technique of RDSA.Conclusion The RDSA is very useful in the preoperative diagnosis and selection of treatment for the diseased arteries.

Objective To explore the effectiveness of transcranial magnetic stimulation (TMS) combined with hyperbaric oxygen (HBO) in treating cerebral infarction.Methods Totally 120 patients with cerebral infarction were randomly divided into a control group,a treatment group A and a treatment group B,40 cases in each group.The control group was given conventional treatment,the treatment group A was treated by HBO on the basis of conventional therapy,and the treatment group B was treated by HBO combined with TMS,10 d for a period of treatment.Before and after 2 courses of treatment,all patients' neurological defect was evaluated using National Institutes of Health Stroke Scale (NIHSS).Their central motor conduction time (CMCT) and the expression of brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF) were also assessed.Results After treatment,the average NIHSS score and effective rate of the treatment group B was (7.35 ± 1.98) and 92.5％ respectively,significantly better than the other two groups.Moreover,the average BDNF content [(4.96 ± 1.20) ng/ml] and NGF content [(152.36 ± 18.01)pg/ml] of the treatment group B after treatment were significantly better than before treatment,and those of the other two groups after treatment.Conclusion TMS combined with HBO is effective in treating cerebral infarction.This may relate to its strengthening the expression of neurotropic factors.

Objective To discuss the practice of nursing management model of stroke unit based upon the international standards implemented in the neurological unit.Methods The experiences of the stroke unit management were summarized and applied to instruct the clinical practice.Results After the implementation,the average hospitalization days,the proportion of drugs,medical cost,and mortality rate decreased.The satisfactory degree of patients with the stroke unit increased.Conclusions The nursing management model of stroke unit not only improved the quality of nursing service to stroke patients,but also decreases the mortality and disability rate,shortened the length of hospital stay,and enhanced the satisfaction degree of patients and their family members.
