Objective To study the characteristics of working memory impairment in patients with lacunar cerebral infarctions(LCI).Methods 42 patients proved by clinics were chosen,and divided into two groups:multiple and single LCI groups,versus left,right and double side infarction groups.Their working memory status were evaluated and compared with Digit Ordering Test,Corsi block task,House Visual Span Test and Stroop Digit Counting Test.All scores were analyzed statistically.Results(1)All scores of the four types of Tests in multiple LCI group were significantly lower than those in single group(P0.05).Conclusions Multiple LCI is closely related to working memory impairment.Left brain infarction may induce verbal working memory impairment,and right infarction may induce spatial working memory impairment,but object working memory impairment may related to double side of brain infarction.It suggested that in the physiological structure,different components of working memory regions had dissymmetrical effect in two sides of brain.

The virus family Arenaviridae is a diverse group of RNA viruses and includes the etiologic agents of several emerging zoonoses that are characterized by high case-fatality rates.The purpose of this article is to review the major features of the zoonotic arenaviruses from the angles of their taxonomy and classification,epidemiology and ecology,mode of transmission,clinical signs,prevention and control,etc.Which are important for the reason that viruses causing severe disease in humans are re-emerging somewhere the world.

Bias in undoubled blind design in the clinical trial of Chinese herb affects the evaluation of efficacy and safety. With two examples, the paper recommended a "segregation" technique to minimize the bias in investigators during undoubled blind trial. The results showed that this method combined other strict means can achieve the conclusions the same as a double blind trial.

Hypertension is a significant medical and public health issue which puts an enormous burden on health care resources and the community. It is a chronic medical condition in which the systemic arterial blood pressure (BP) is elevated. Serious complications including cardiovascular and cerebrovascular diseases would be preventable if the rise in BP with age could be prevented or diminished. The majority of hypertensive patients require long-term treatment. Oral antihypertensive drugs, lifestyle modification including exercise and dietary modification are milestones for hypertension therapy. However, the control rate of hypertension hasn't reached the expected requirements currently. "Three lows" status quo, just low awareness, low treatment, and low control, are still the major problems confronting modern medicine. Recently, uncontrolled factors of blood pressure are widely concerned, which include insomnia, constipation, mood disorders, exogenous, etc. What's more, the control strategies of hypertension should not only pay close attention to "patient's high blood pressure", but also to "hypertensive patient". Therefore, the treatment of uncontrolled factors of blood pressure plays an important role in hypertensive therapy, which could be further research priorities.

Essential hypertension is one of the most prevalent and important public health concerns in both westernized and developing countries. Recent studies have demonstrated that successful long-term treatment of hypertension has a significant impact on morbidity and mortality from cardiovascular diseases (CVDs) and stroke. Chinese classical formulas, which are important components of traditional Chinese medicine (TCM), have been increasingly accepted by patients with CVDs worldwide. According to TCM theory and syndrome differentiation, hypertension could be categorized into 3 patterns including fire syndrome, fluid retention syndrome, and deficiency syndrome. Chinese classical formulas, including Chaihu Jia Longgu Muli tang, Tianma Gouteng yin, Zhen Gan Xifeng tang, Banxia Baizhu Tianma tang, Liu Wei Dihuang wan, etc, play an important role in the treatment of essential hypertension, which could be further research priorities.

Objective To investigate the expression level of human telomerase RNA component (hTERC) and C-myc in cervical lesions.Methods Fluorescence in situ hybridization (FISH) was applied to detect hTERC and C-myc expression in 62 cases of cervical tissue including 35 cases of cervical intraepithelial neoplasia,8 cases of invasive cervical cancer,19 cases of inflammation as controls.Results The positive rates of hTERC on chromosome 3 in chronic cervicitis organizations,CIN Ⅰ,CIN Ⅱ-Ⅲ and cervical cancer were 5.3 ％ (1/19),16.7 ％(2/12),87.0 ％ (20/23),87.5 ％ (7/8) (x2 =36.299,x2 =40.237,P ＜0.01).The positive rates of C-myc in chronic cervical inflammation organization,CIN Ⅰ,CIN Ⅱ-Ⅲ and cervical cancer were 5.3 ％ (1/19),8.3 ％ (1/12),78.3 ％ (18/23),62.5 ％ (5/8) (x2 =30.200,x2 =34.224,P ＜0.01 ).The differences among groups were statistically significant.hTERC had a positively correlation with C-myc expression (r =0.514,P ＜ 0.01).Conclusion The expression of hTERC and C-myc on chromosome 3 is closely related to cervical cancer progression.

Hypertensive renal damage is based on the extent and duration of hypertension, renal damage caused by varying severity. Hypertensive renal damage due to various causes imbalance of vascular active substances, renal arteriosclerosis, so that the abnormal renal hemodynamic, renal ischemia, low specific gravity of urine, low osmotic pressure and urine. The rapidly increasing incidence of hypertensive renal damage has become one of the most important reasons of end stage renal disease (ESRD). Effective treatment of hypertension is limited by poor compliance and significant adverse reaction of antihypertensive drugs. Therefore, some patients have turned to Chinese medicine (CM), hoping that such treatments might improve the efficiency. The author reviews relevant theory and the latest researches, on the basis of combining diseases and syndrome, discusses state and achievement of hypertensive renal damage with Chinese herbal medicines from fundamental and clinical research and action mechanism from standpoints of Chinese herbal compound and herbal effective chemical composition to take future research for important reference.

MicroRNA(miRNA) is involved in virtually all biologic processes, including cellular proliferation, apoptosis, and differentiation. Thus, miRNA deregulation often results in impaired cellular function and disease development, so miRNAs have potential therapeutic relevance. The elucidation of these processes regulated by miRNAs and the identification of novel miRNA targets in the pathogenesis of hypertension is a highly valuable and exciting strategy that may eventually led to the development of novel treatment approaches for hypertension. Several mechanisms have been implicated in the pathogenesis of hypertension: overactivation of therenin-angiotensin-aldosterone system (RAAS), dysfunction of the vascular endothelium, damnification of vascular smooth muscle. To maintain and restore target organ expression of miRNA stable may be a new strategy for treatment of hypertension. The article reviews pathogenesis of miRNA and hypertension, researches of miRNAs as biomarker and therapeutic target, discusses advances in miRNA-based approaches that may be important in treating hypertension.

Objective To study the vestibular aqueduct(VA) with CT in Meniere,s disease(MD). Method The experiment consisted of three groups: normal ear group, non-MD vertigo group and MD group. VA in each group was examined with CT, and the width of the external aperture of VA was measured.Result VA in normal ear group and non-MD vertigo group was well visualized,and non-visualization rate was 9.1%. VA non-visualization rate in MD group was 75%, external aperture was narrowed in VA patients. Conclusion non-visualization or narrowing of the enterhal aperture can be considered as one of the diagnostic sings of MD.
