Objective To assess the effects of management by diabetes specialist nurse (DSN) on blood glucose control.Methods A comprehensive search of databases was carried out including PubMed,the Cochrane Library,Web of Science,China National Knowledge Infrastructure (CNKI),Chinese Biomedical Literature Database (CBM),China Scientific Journal Database (VIP) and Wanfang Database from their inception to November 2013 in any language to identify trials.Searching of relevant publications was undertaken to identify additional trials.Randomized controlled trials and quasi-randomized controlled trials dealing with the effects of management by DSN on glycosylated hemoglobin (HbA lc) were included in the review.Two investigators performed data extraction and quality assessment independently.Statistic analysis were carried out using RevMan5.2 software.Results Eighteen trials were included finally.Meta-analysis showed that management by DSN can better control the blood glucose of patients(WMD=-0.63,95％CI-0.88--0.38),but the effect was influenced by intervention time,location and type of the diabetes mellitus.Conclusions The presence of a DSN can improve patients' blood glucose control,especially in the long-term control of blood glucose.

Objective To find T2N0M0 colorectal cancer patients at high risk for relapse or metastasis.Methods From January 1993 to December 2014,339 patients with histologically confirmed stage T2N0M0 primary colorectal cancer treated by radical surgery with complete clinical follow-up data were enrolled into this study.Survival rates were calculated using Kaplan-Meier method,and survival cures were compared using the Log-rank test.Cox proportional hazards model was used to analyze the significant factors defined in univariate test.Results The 5-year and 10-year overall survival rates were 83.0％ and 68.9％,respectively.Male gender,old age,lymphovascular involverment,perineural invasion,poor differentiation and invasive micropapillary carcinoma were associated with low cancer-specific survival rates in Kaplan-Meier analysis.Multivariate analyses revealed male gender,old age,lymphovascular involverment,poor differentiation and invasive micropapillary carcinoma as significant independent factors predicting poor prognosis.Conclusions Male gender,old age,lymphovascular involvement,poor differentiation and invasive micropapillary carcinoma are risk factors predicting poor prognosis for T2N0M0 colorectal patients.

Animal medicines mainly contain protein which was organic molecule with quaternary structure and had the property of thermal denaturation. When suffering from heat for a consistent time, the native conformation of protein would be destroyed. After denaturation the biological activity of protein will lose and some physicochemical and biochemical properties will be changed. Leech was a classical animal medicine in the views of traditional Chinese medicine (TCM) which had the functions of breaking stagnant and eliminating blood stasis. In the usage history, it was processed for a long time. No matter stir-frying leech with talc powder embodied in Chinese Pharmacopoeia or stir-baking with wine as a distinctive method in Beijing district, the process procedure was basically performed under high temperature. The purposes and intentions of process are mostly limited to technology conditions at specific historical period. In this article, based on existing processing procedure and its character of Leech, the changes of active components and pharmacological activities before and after processing under high temperature were summarized. The results demonstrate that the protein of leech would be denaturated; some active peptide such as hirudin were partly or totally destroyed; some toxic mineral elements, such as Pb, Hg, Cd, were decreased; at the same time, heating can promote some chemical components transforming into hypoxanthine which had the function of antihypertensive, antiasthmatic and antalgic. Consequently, after processed under high temperature, the purpose of decreasing toxicity and alleviating the strong property was achieved. Pharmacological changes of leech processed under high temperature were mainly manifested in the anticoagulant and antithrombotic activity, etc. Based on current processing research status about animal medicine leech, future research methods and directions on scientific connotation of leech processed under high temperature were put forward in this article.

Objective To assess the feasibility and clinical value of high-resolution magnetic resonance imaging (HRMRI) in patients with symptomatic severe intracranial stenosis (SSIS).Methods HRMRl wasperformed with a 3.0 T MR scanner on 5 patients with symptomatic middle cerebral(n=3) or basilar (n=2) arterial stenosis of≥70% confirmed bv DSA.Image diagnosis Was made on the basis of HRMRI findings of vessel wall at the stenotic segment by 2 neuroradiologists blinded t0 patient's status.Results Three of the five patients were diagnosed to have advanced intracranial atherosclerosis based on the presence of a complex eccentric atherosclerotic plaque containing a large lipid-rich necrotic core with a heterogeneous post-contrast enhancement and with signs of ruptured fibrous cap.Two other patients were likely to suffer from non-atherosclerotic lesion.HRMRI revealed an iso-signal septum in the arterial lumen attaching to the slighfly thickened arterial wall that was iso-signal with a homogeneous post-contrast enhancement in one patient and an obviously concentrically thickened arterial wall with hypo-intense signal on T1 WI and slightly high signal on T2 WI and PDWI and without any post-contrast enhancement in the remaining patient.Conclusions In vivo HRMRI in patients with SSIS is technically feasible.It provides detailed information of intracranial arterial wall at the stenotic segment.

Objective To study the effect of abnormal left ventricular diastolic function(LVDF)on the onset and severity of atrial or ventricular arrhythmia in elderly essential hypertensive patients.Methods The 210 elderly essential hypertensive patients were enrolled in this study. Their arrhythmias were monitored by 24-hour ambulatory electrocardiogram. The essential hypertensive patients were referred for Doppler echocardiography to evaluate left ventricular function, while patients with abnormal systolic function were excluded, and then the patients were classified as normal LVDF and abnormal LVDF including, impaired relaxation, pseudonormal, and restrictivelike filling patterns. Results In 210 elderly essential hypertensive patients, 147 (70%) cases were diagnosed as atrial arrhythmia and 102 (49%) cases as ventricular arrhythmia (χ2 = 19. 975, P ＜ 0.05 ).Morbidities of atrial (89%) or complex atrial arrhythmia (49%) as well as ventricular (63%) orcomplex ventricular arrhythmia (30%) were significantly higher in abnormal LVDN group than in normal LVDN group (40%, 13%, 26% and 7%, χ2 = 56. 723 、 28. 359 、 28. 076、15. 9102 , all P＜0. 05). The morbidities of arrhythmias were higher in hypertensive patients with pseudonormal and restrictiveike filling patterns than in other groups 93.6% and 96. 4%. Conclusions Abnormal left ventricular diastolic function affects on the onset and severity of atrial or ventricular arrhythmia in elderly essential hypertensive patients, and complex atrial or ventricular arrhythmia is easier found in hypertensive patients with pseudonormal and restrictivelike filling patterns.

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.

In the present study, the AC impedance of rat blood was measured with Agilent 4294A impedance analyzer in the frequency range of 10(4)-10(8) Hz, and the effect of simulated weightlessness (SWL)on electrical properties of rat blood was investigated by analyzing the data characteristics with the use of electrical impedance spectroscopy, the Bode diagram, the Nyquist diagram and the Nichols diagram. The results demonstrated 60 days SWL caused some changes: (1) the electrical impedance of rat blood were reduced, mainly in the real part of complex impedance (Z'o and Z'infinity), the electrical impedance modulus amplitude (|Z*|o and |Z*|infinity), the impedance relaxation strength (deltaZ', delta|Z*|) and the logarithm of impedance modulus amplitude at low frequency (Log |Z*|o) were lower than that in the control (CON) group; (2) the characteristic frequency of the electrical impedance spectrum of rat blood and the phase angle were increases, mainly in the characteristic frequency (fc1, fc2) and the phase angle [theta(p) (degree), theta(p) (radian)] increased compared with that in the CON group. These data indicate that SWL leads to reduced resistivity and enhanced conductivity of blood.
