The administration status of enteric coated aspirin in 348 diabetic patients aged over 40 from Xujiahui Subdistrict of Shanghai was surveyed. One hundred and two out 348 patients ( 29. 3% ) used aspirin regularly, among them only 36 cases used the correct dosage (75 - 162 mg/d), accounting for 10. 3% (36/348) of all patients surveyed. The results indicate that aspirin was not used properly in diabetic patients to prevent the heart and cerebrovascular diseases,and it is necessary for medical providers to promote health education for diabetic patients.

A major task in clinical trials and researches is subject recruitment, however there probably exist ethical issues in the process of recruitment, such as the selection of subjects, recruitment methods, document de-scription,reward and compensation. This paper is to discuss the relevant ethical elements through cases analysis. It put forward that only obeying ethical codes, implementing informed consent, and playing the function of ethics com-mittee, the rights and interests of subjects can be protected.

Based on the analysis of current status of medical service process including the service in out-patient, hospitalization, test, examination, nursing, and so on, the paper describes the bottlenecks and major existing problems of current medical service process. And it further discusses how to make full use of the advanced health information technology, make scientific and reasonable arrangements for all links of medical service, reconstruct medical service process facing the patients, and optimize and reengineer the medical service process.

lntraocular lens ( lOL) often has different degrees of tilt, decentration and rotation in the eye. The deflection of lOL is an important factor to impact on the visual quality of the patients with cataract surgeries. Vision was commonly used to evaluate visual quality before. ln recent years, some new methods are also introduced to evaluate visual quality, such as optical aberration, modulation transfer function ( MTF ) and subjective visual perception. They show that the lOL deflection will cause decreases in eyesight and MTF, cause increase in aberration, lead to ametropia and so on. Therefore, a better evaluation of the effects of lOL deflection on visual quality, has significance for lOL selection, positioning and cataract individualized treatment.

Electrical stimulation is a common technology to treat neurogenic bladder dysfunction secondary to supersacral spinal cord injury. This paper reviews the historical development of this treatment and current status.

Objective To explore the clinical effects of ropivacaine in combined spinal-epidural anesthesia (CSEA) in the aged patients undergoing lower limb surgery. Methods Sixty patients, aged 65 and over, in American Society of Anesthesiologists (ASA) physical status Ⅱ-Ⅲ, and undergoing internal fixation surgery for lower limb bone fracture, were randomly assigned to three groups in equal number: group R1 (hypobaric ropivacaine for lumbar anesthesia), group R2 (hyperbaric ropivacaine for lumbar anesthesia) and group B (bupivacaine for lumbar anesthesia). The observed variables included the changes in blood pressure and heart rate, sensory block level and motor block status. The drug consumption in epidural anesthesia and the peri-operative side effects were noted. Results The anesthetic efficacy was satisfactory in all patients. The onset time of anesthesia in group B (54.05?3.80 s) was obviously shorter than that in group R1 and group R2 (61.10?4.96 and 60.95?3.94 s, respectively, P

Objective To study the relationship between ambulatory arterial stiffness index and extent of coronary atherosclerosis.Methods All subjects were underwent coronary CT angiography.Ambulatory arterial stiffness index(AASI) was measured before coronary CT angiography.AASI value between different periods in each group were calculated and compared.Results AASI between different periods in the normal control group and coronary heart disease group existed statistical difference (P ＜ 0.05).The extent of coronary sclerosis and AASI between different periods in different coronary artery lesions groups were statistically different(P ＜0.05),AASI was proportional to the degree of coronary sclerosis,24 h AASI,DAASI,NAA SI were related to extent of coronary atherosclerosis lesions,the correlation coefficient between NAASI and extent of coronary atherosclerosis was the largest.Conclusion AASI night is related to coronary atherosclerosis most closely,namely the higher the value of the nighttime AASI,the greater the degree of coronary atherosclerosis.

Objective To analyze tissue-specific expression and polymorphic regulation of the UDP - glucuronosyltransferase (UGT) 1A gene in human tissue. Methods Forty colorectal cancer tissue. 20 normal colorectal tissue and 10 normal liver tissue were studied. UGT 1A transcriptions were investigated by exon-1 specific RT-PCR. UGT 1A proteins were studied using Western blotting analysis. Meanwhile catalytic activity of microsomes was evaluated using N-hydroxy-PhiP. Results (1) UGT 1A mRNA expressions were found to be significantly down-regulated in colorectal cancer tissue as compared with the surrounding normal tissues(P

Objective To observe the therapeutic effect of pericarpium zanthoxylum oil on experimental hyperlipemia in mice. Methods Hyperlipemia model was reproduced in mice, and then pericarpium zanthoxylum oil was garaged for 4 weeks. Blood samples were obtained from retro-ocular vessel. The levels of blood lipids were determined, the hemorrheology parameters were determined by hemorrheometer, and the pathological changes in the liver of mice were observed microscopically. Results Zanthoxylum oil could obviously reduce contents of TC, TG, LDL-C (P
