With the development of modern medical detection technology,the requirement for ophthalmic diagnosis is raised,and many new measurement methods begin to apply in research and clinical,which makes the detection methods in the field of ophthalmology more accurate and comfortable.Optical coherence tomography angiography is a novel and noninvasive flow imaging technique,and it has the advantages of high resolution,fast scanning,as well as quantifying blood flow.Meanwhile,this technique can not only qualitatively analyze the shape of ocular blood vessels,but also be able to measure the ocular blood vessels and blood flow non-invasively,as well as to assess the depth of lesions.At present,with a wide clinical application in ophthalmology,optical coherence tomography angiography will be reviewed in this paper.

Cerebral infarction is a polygenic disease caused by genetic factors and environmental factors.The first discovery in the Icelanders is that the ALOX5AP and PDE4D gene polymorphism may be associated with cerebral infarction.So far,many conclusions of foreign studies are still controversial.This article will summarize the research status and the progress of these two genes.

Chlamydia pneumoniae(Cpn) is one of the most common pathogens causing human respiratory tract infection.They cause acute respiratory tract infection,atherosclerosis and many other diseases. Cpn infection often recur or remain persistent,which may induce Th1-type response.At the same time,antibody-mediated immune and Toll like receptor play an auxiliary role.In this review,the author summarized advances in the immune response to Chlamydia pneumoniae infection.

Atherosclerosis is a chronic inflammatory disease of the vascular walls. As the essential mediators of inflammation, cytokines play important roles in atherosclerosis. Through widespread and penetrating studies, many cytokines, such as TNF-, IL-1, IL-6 and IFN-, are found involved in the development of atherosclerosis, as well as the related signal transduction pathways such as the NF- B pathway, the JNK / AP-1 pathway, and the JAK / STAT pathway. This implies that cytokines have a favorable perspective of clinical application. A few cytokines are identified as biomarkers, which help the early diagnosis of the disease and estimation of the risk of the clinical vascular events. Meanwhile, great progress has been made on the cytokine-targeted treatment of atherosclerosis, providing a novel therapy in the treatment of the disease.

OBJECTIVE To explore the status of nosocomial infection,infection sites of patients and susceptible factors of infection in neuro-intensive care unit(NICU) in order to correspondently prevent and control the occurrence of nosocomial infection.METHODS The clinical data of 471 patients admitted to NICU from Mar 2005 to Feb 2006 were investigated retrospectively.RESULTS Out of 471 cases in one year,a total of 90 cases of nosocomial infection were found.The rate of nosocomial infection was 19.11%.Among the nosocomial infection sites,the respiratory tract was the most frequent one(46.67%).The second was urinary tract(44.17%).The patients aged of more than 60 years,or with urethral catheter,mechanical ventilation,vein intubations,or with long medical intubation suffered infection more susceptibly than other patients.The infection rate of nosocomial infection was significantly different from hospitalization group.Sex was not evidently related to nosocomial infection.CONCLUSIONS The rate of nosocomial infection in NICU is largely higher than the total rate of infection.The susceptible factors are age,long-term hospitalization,invasive operations and long medical intubation.

OBJECTIVETo assess the efficacy of Yishen Jiejing Decoction (YJD) in treating poststroke shoulder-hand syndrome (SHS) patients of yin deficiency yang hyperactivity with blood stasis stagnation collaterals syndrome.

METHODSTotally 60 SHS patients of yin deficiency yang hyperactivity with blood stasis stagnation collaterals syndrome were randomly assigned to two groups, the treatment group and the control group, 30 cases in each group. Conventional rehabilitation training and therapeutics were applied in all patients. Besides, patients in the treatment group took 50 mL YJD, twice a day. One month without interruption consisted of one course of treatment. The curative effects of each group were evaluated respectively before treatment and at one month after treatment. The neurologic impairment, TCM syndrome, and the improvement of upper limbs movement were assessed by the neurologic impairment integral, scoring for TCM syndrome diagnostics, Fugl-Meyer Assessment (U-FMA). Adverse reactions were observed at the same time.

RESULTSThe effective rate of stroke was 86.67% and the effective rate of SHS was 90.00% in the treatment group, higher than those of the control group (P < 0.05). Both groups got improvement in neurologic impairment, stroke induced blood stasis syndrome, yin deficiency yang hyperactivity syndrome, and the improvement of upper limbs movement after treatment (all P < 0.05). Besides, all the improvement was obviously superior in the treatment group (P < 0. 05). No adverse reaction occurred during the course of treatment.

CONCLUSIONThe curative effect of YJD combined with conventional rehabilitation training was confirmative and superior to the control group.

Newer retinal imaging technologies help us in understanding the pathogenesis of many retinal pathologies,such as diabetic retinopathy,age related macular degeneration,glaucoma and uveitis.Early detection of these retinal diseases can prevent the onset of progressive vision loss,and aid in the development of new treatment options.Retinal functional imager (RFI) is an unique and noninvasive functional imaging system.Unlike most of the available newer retinal imaging tools,the RFI not only shows retinal structural changes,but can directly monitor functional changes and measure hemodynamic parameters,such as retinal bloodflow velocity,oximetric state,etc.This article reviews the utility progress of RFI in various retinal diseases.
