Purpose] This paper discusses, in the information era, how to improve col ege English teachers ’ digital literacy. [Method] A questionnaire survey is carried out of the status of col ege English teachers ’ digital literacy in Zhejiang. [Results]Only 25% universities where the respondents work are wel equipped with adequate digital facilities.54% respondents haven ’t received any training in digital technologies and teaching methods. Most of respondents (90%) are interested in digital technologies;however, only 56%of them often use them in class. 90%respondents consider it necessary to receive training in digital teaching technologies. [Conclusion] Firstly, local universities should offer teachers better teaching facilities, more educational resources and training courses; secondly, education of digital literacy and teaching courses should be combined; final y, teachers should possess a correct judgment and improve their awareness of negative information in the virtual environment with self-protection consciousness.

Objective:To observe the clinical efficacy and safety of traditional Chinese medicine Xiaozuo decoction combined with 0. 025% vitamin A for external use in the treatment of acne vulgaris. Methods:Totally 86 patients with acne vulgaris were randomly di-vided into the treatment group and the control group with 43 ones in each. The treatment group was treated with Xiaocuo dcoction, 1 dose/day, and the control group was orally treated with erythromycin ethylsuccinate, 0. 25g per time, 3 times per day. The treatment course was 6 weeks, and both groups were treated with 0. 025% tretinoin cream once every night. The clinical efficacy and adverse drug reactions were compared between the two groups. Results:The obvious effective rate of the treatment group and the control group was 69. 77% and 41. 86%, respectively, and the total effective rate was 88. 37% and 69. 77%, respectively. There was significant difference in the obvious effective rate between the two groups (P<0. 01), while there was significant difference in the total effective rate between the two groups (P<0. 05). Recurrence rates of two groups were 10. 00%and 22. 22%,respectively,and there was no sig-nificant difference (P>0. 05). There were no serious adverse reactions in the two groups. Conclusion: Xiaocuo decoction combined with 0. 025% tretinoin in the treatment of acne vulgaris has promising clinical efficacy with high safety.

It has been shown that MR imaging of breast is superior to conventional mammography and ultrasonography on early diagnosis and cancer staging on breast cancer due to MRI’s high soft-tissue contrast and no radiation. The concept of multidisciplinary treatment of breast cancer has been increasingly accepted in clinical practice of breast cancer care. Investigation of breast MRI on cancer staging, selecting conservative therapy, detecting the primary malignant of patients presenting as axillary metastases, evaluating residual disease after neoadjuvant chemotherapy(NAC), predicting response in the early phase of treatment as well as monitoring recurrence during follow-up has been carried out along with its board clinical application. The advantages of breast MRI in mapping the disease accurately provide measures to select appropriate use of variable treatments.

Cerebral small vessel disease (CSVD) refers to a group of pathological processes caused by various causes that affect the microarteries,small arteries,venules and capillaries in brain tissue.Inflammation and endothelial dysfunction may play an important role in mechanism of leading to CSVD-related changes.The research in related fields is expected to become an important means of in-depth understanding of CSVD.The driving factors of brain dysfunction caused by CSVD and the relative role of vascular lesions and primary neurodegenerative changes in the process of CSVD remain unclear.The examinations reflecting cerebrospinal fluid components of the central nervous system degenerative lesions and vascular lesion process can provide important information.The related biochemical changes may become an early identification indicator of CSVD,at the same time it can enhance the understanding of its characteristic mechanism.In addition,CSVD specific biomarkers can also play an important role in monitoring the therapeutic effects.

Cerebral small vessel disease (CSVD) is an important cause of functional incapacitation,disability,and cognitive impairment in the elderly.Subcortical CSVD can lead to lacunar infarcts and progressive white matter lesions.CSVD cognitive impairment is an important subtype of vascular cognitive impairment (VCI).The dementia caused by it accounts for about 36%-67% of vascular dementia.With the development of technology,neuroimaging and its related markers has become a powerful tool for the diagnosis of CSVD and cognitive impairment.The clues of the CSVD pathogenesis can also be found in the field of brain cognition.STandards for ReportIng Vascular changes on nEuroimaging (STRIVE) has established the neuroimaging markers of 6 critical damages,including recent small subcortical infarcts,lacunar foci that are assumed to be the origin of blood vessels,white matter hyperintensities that are assumed to be the origin of blood vessels,perivascular spaces,cerebral microbleeds,and brain atrophy.This article reviews the correlation between VCI caused by CSVD and imaging features.

Patient, 30-year-old, male,was admitted to our hospital because of discontinuously spit fresh blood without any inducing factors for three days. In the course, the patient suffered mild dry sensation of pharyngeal, poor spirit condition, fatigue, poor sleep, poor appetite and was with black stool 2 times. Physical examination: T36. 6°C, R 21/min, P98/min, BP135/90 mmHg (1 mmHg = 0.133 kPa). Bilateral tonsils were III hypertrophy and with scar shape surfaces. The left tonsil's surface had longitudinal small blood vessels markedly dilated. His oropharynx, laryngopharynx and laryngeal did not be find any obvious bleeding sites. Laboratory findings: WBC 13.82 x 10(9)/L, N 0.8084, L 0.1632, Hb 81.00 g/L, HCT 25.20; PT 9.60 s, APTT 25.50 s, TT 15.80 s, FIB 1.900 g/L. After 3 hours of admission,the patient spit out fresh blood again,checked the body to see:the left peri-tonsil with fresh blood and found a slowly bleeding site at the 1/3 junction of the middle lower part of left tonsil's rear surface, the size was about 0.5 cm x 0.6 cm. We finally diagnosed spontaneous tonsillar hemorrhage and successfully managed with low-temperature radiofrequency technology.

With the development of our understanding of the physiology,pathophysiology and pharmacology of pain,preemptive analgesia has been widely introduced into clinical treatment.This review focuses on the mechanism and application of preemptive analgesia in acute pain therapy.

OBJECTIVE To investigate the prevelance of hospital infections of sugical patients in neurosurgery department and analyze the risk factors. METHODS Retrospective survey was made for 456 operative inpatients in neurosurgery department from Jan 2007 to Dec 2008. RESULTS Among them there were totally 66 cases of hospital infections (14.3%). 82 case-times of hospital infections (17.98%)were found. The infections were found located mostly in respiratary tract infection (51.51%) and gastro-intestinal tract infection (16.66%). CONCLUSIONS Surgical patients in neurosurgery department are high-risk group of hospital infection. Normalizing nursing adminstration and strengthening monitoring are effective methods to prevent nosomial infections.

Objective To explore the diagnostic value of indirect magnetic resonance(MR) arthrography in detecting meniscus tears of the knees.Methods Routine plain MR of the knees followed by indirect MR arthrography was performed in 56 knees with suspected meniscal tears clinically.All cases had subsequently arthroscopic examination or operation.The sensitivity and diagnostic accordance of routine plain MR and indirect MR arthrography were compared based on the result of arthroscopic examination or operation. Results The signal intensity in the area of meniscal tears on image of indirect MR arthrography was obviously higher than that of routine plain MR.The diagnostic accordance rate of indirect MR arthrography was 78.67% while the routine plain MR was 52.20%,and the difference was statistically significant(?~2=21.066,P
