Photography of slit-lamp biomicroscopy combined with retro-illumination photography is the gold standard in cataract evaluation. However the application is limited due to its complexity and low efficiency. We introduce digital non-mydriatic fundus photography as a new method for cataract screening in patients with visual impairment,which might play an important role in screening low vision and blindness caused by cataract. Two distinguished benefits are found in this method including compatibility for tele-diagnosis,and integration with screening of glaucoma and diabetic retinopathy. Cautions should be made on the photographs in which media opacity derived from other than cataract or low quality photos due to small pupils.

Age-related macular degeneration ( AMD ) is the main cause of blindness in the people older than 50 years old. In recent years, following the improvement of imaging techniques in ophthalmology, the pathogenesis of the disease, the level of diagnosis and efficacy evaluation ability greatly improved. In this paper, we reviewed and discussed the recent advancement on imaging research of age-relate d macular degeneration.

Private cloud is an internal cloud featuring multi-tenant,dynamic configuration and optimization infrastructure,which enables developers to achieve service self-deployment and self-hosting within security coverage of the enterprise data center.This paper introduced the concept of cloud computing.Then it went on to present the private cloud architecture of the hospital by analysis of problems in the hospital including information construction costs,management and maintenance,and information expansion.In the end,the authors analyzed the cloud computing service model,hospital private cloud architecture,along with outcome analysis for hospital private cloud implementations.

Pollution and control of microcystins released during the toxic bloom was reviewed in the present paper. As a risk factor in safety assessment, microcystins aroused broad attention. It was a topic of general interest that how to control microcystins reproduction and how to enhance the degradation of microcystins in the water treatment procedure. Based on the state of China, it was considered that a combined method of biological, physical and chemical treatment should be the best way to control microcystins pollution in drinking water.

Objective To observe the clinical efficacy of needle knife, Governor-Vessel moxibustion plus medication in treating ankylosing spondylitis (AS).Method Forty AS patients were randomized into a treatment group and a control group, 20 cases in each group. The control group was intervened by intravenous administration of Ossotide injection, while the treatment group was by needle knife and Governor-Vessel moxibustion in addition to Ossotide injection. Before and after the intervention, the symptoms and body signs, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Bath Ankylosing Spondylitis Functional Index (BASFI) were observed in the two groups, and the clinical efficacies were compared between the two groups.Result The total effective rate was 90.0% in the treatment group versus 75.0% in the control group, and the between-group difference was statistically significant (P<0.05). After the intervention, the symptoms and body signs (spinal pain score, Schober test, morning stiffness duration, chest expansion degree, and occiput-wall distance) were changed significantly in both groups (P<0.05). The BASDAI and BASFI scores were significantly changed after the intervention in both groups (P<0.05). The BASDAI and BASFI scores in the treatment group were significantly different from those in the control group after the intervention (P<0.05).Conclusion Needle knife plus Governor-Vessel moxibustion and medication is an effective approach in treating AS.

Objective To compare the influence of different end-tidal concentrations of sevoflurane on transcranial electrical four-limb muscle motor evoked potential (MEP) monitoring. Methods Twenty ASA Ⅰ-Ⅱpatients aged 23-62 years undergoing craniotomy were enrolled. Triangular muscle, biceps brachii muscle, triceps brachii muscle, brachioradialis muscle, extensor digitorum communis muscle, abductor pollicis brevis abductor digiti minimi muscle, rectus femoris muscle, tibialis anterior muscle, gastrocnemius muscle and abductor hallucis were selected for MEPs recording. Sevoflurane was introduced at 0.5, 0.75, 1.0 and then 1.3 MAC (15 min each), and the effects on MEPs were studied. Results ①Maximum MEP amplitude was observed at abductor pollicis brevis muscle in upper limb and abductor hallucis muscle in lower limb at baseline and 0.5 MAC. Up to 1.0 MAC, there was no significant difference in MEP amplitude among extensor digitorum communis muscle, abductor pollicis brevis and abductor digiti minimi muscle. ②The success rate of MEP recording from abductor pollicis brevis muscle and abductor hallucis muscle was 100% during the administration of 0.5-1.0 MAC sevoflurane. ③The MEP amplitude was decreased and the latency was increased in a sevoflurane dose-dependent manner. Conclusions Abductor pollicis brevis muscle and abductor hallucis muscle were suitable for MEP monitoring during the administration of 0.5-1.0 MAC sevoflurane.

According Ming dynasty,Qing dynasty established the imperial drug institution(IDI) and set up service offices or pharmacy in several temporary imperial palaces besides office in Forbidden City,which was IDI offices outside Forbidden City.Base on assorting historical information and literature,eld research about historical remains,this article preliminary clari ed the o ces' names and locations of IDI outside Forbidden City.

Through the questionnaire on bilingual teaching in medical students,some problems were presented. This paper is intended to discuss the necessity and the present condition of bilingual teaching and find out some measures to improve bilingual teaching quality.

Objective To investigate Hysterothylacium aduncum (Anisakidae) infection in marine fishes from Bohai Sea and Yellow Sea. Methods Nematodes were collected from the digestive tract of fishes, fixed with hot 4% formalin and preserved in 70% ethanol for study. The specimens were cleared in lactophenol for light microscopical examination, and properly treated for scanning electron microscopy (SEM). Results Among the fishes examined, 14 out of 93 species (15.1%) were found infected by H.aduncum, with a higher prevalence in the fish of Lophius litulon(66.7%), Scomber-omorus niphonius(47.5%), and Gadus macrocephalus(33.3%). H.aduncum infection was first recorded in elasmobranch-Raja smirnovi. Morphological differences of H.aduncum were observed, including the width of lateral alae and the length of intestinal caecum. Conclusion H.aduncum in fishes of Bohai Sea and Yellow Sea in China may be a complex species, and its high prevalence in some fishes reminds the risk of anisakiasis by eating raw fishes.
