Metabonomics is the branch of science concerned with the quantitative understandings of the metabolite complement of integrated living systems and its dynamic responses to the changes of both endogenous factors (such as physiology and development)and exogenous factors (such as environmental factors and xenobiotics). As a holistic approach, metabonomics detects, quantifies and catalogues the time related metabolic processes of an integrated biological system, ultimately, relates such processes to the trajectories of the pathophysiological events. Ever since its birth in 1999, metabonomics has already been described in more than 800 scientific papers and half dozen patents, amongst which almost 700 papers were experimental articles. Now, metabonomics has been established as an extremely powerful analytical tool and hence found successful applications in many research areas including molecular pathology and physiology, drug efficacy and toxicity, gene modifications and functional genomics, and environmental sciences. This holistic approach has thus become an important part of systems biology and has now evolved to be a unique part in global systems biology. The essence of metabonomics and some of the present applications were reviewed to illustrate the rapid development of this extremely exciting new frontier.

Objective To investigate the effect of nutritional therapy for an infant with short bowel syndrome (SBS) who had jejuno-colostomy. Methods An individualized nutritional support before and after the closure of jejunum colostomy was provided to a 3-month-old girl with SBS who had jejuno-colostomy so as to find out its influence on prognosis. Results Paren-teral nutrition is a life-saving therapy for infants with SBS. The proper enteral nutrition can improve intestinal tolerance and re-duce the incidence of postoperative complications, and improve outcomes of SBS infants. Conclusions Appropriate nutrition therapy is important to reduce the complications and improve the prognosis of SBS infants.

To explore the feasibility of sevoflurane used in obstetric anesthesia and examine its effects on neonatal Apgar scores.A total of 60 cases of term primipara were assigned into epidural anesthesia assisted sevoflurane inhalation group (experimental group,n =30) and epidural anesthesia group (control group,n =30).In the experimental group after skin incision,the patients could not tolerate the anesthesia mask inhalation of sevoflurane.And the control group received no adjuvant drug.The maternal inhalation of sevoflurane to delivery of fetus after 1 min,5 min,10 min Apgar scores were analyzed.And the inhalation of sevoflurane to fetal childbirth duration were 4-10 min in two groups.The intergroup difference of newborn Apgar scores had no statistical significance (P ＞ 0.05).Epidural anesthesia assisted sevoflurane inhalation for cesarean section had no significant effect on neonatal Apgar scores.

BACKGROUND: Most of the dental metal repair materials contacting Ti implants will cause galvanic corrosion and local environment with positive electricity on the implant interface, which directly affects the status of the tissues, especially bone resorption.OBJECTIVE: To evaluate the galvanic corrosion of commercially pure Ti (TA2 type) coupled with Au alloy, CoCr alloy, Ti alloy, and NiCr alloy in vitro. METHODS: Circuit of commercially pure Ti contacting with Au alloy, CoCr alloy, Ti alloy, and NiCr alloy was simulated in vitro in artificial saliva, and the common potential and galvanic current in 15 hours were recorded to draw current-time curves. RESULTS AND CONCLUSION: The galvanic current became stable after 8 hours of contacting. The galvanic current was the greatest in Ti/Au, followed by Ti/CoCr, Ti/Ti alloy, and then Ti/NiCr. Results indicated that the galvanic corrosion of the couple of Ti and Au alloy is the lowest. Au alloy is the most suitable material for implant superstructure. The galvanic corrosion of the couple of Ti and NiCr alloy is the highest, so NiCr alloy is not acceptable for implant superstructure.

Objective To test the serum albumin level in patients having the peritoneal dialysis,and investigate its relationship with C-reactive protein(CRP)level or other inflammatory complications. Methods Sixty patients having peritoneal dialysis treatment were divided into two groups based on the serum albumin(ALB)level,patients had normal ALB level were included into group A,while the patients with serum hypoproteinemia were included into group B. The serum level of CRP,transferin(TF)and nutritional status were compared between two groups,and their relationship with clinical complications were evaluated. Results The serum CRP level in patients of group B(8.40 ± 1.32)mg/L was significantly higher than group A(2. 14 ±0.87)mg/L(P ＜0. 01). Patients from group B had more inflammation complications,such as peritonitis(6. 7%),pneumonia(13. 3%),cardiovascular disease(16.7%). Conclusions The continuous ambulatory peritoneal dialysis patients accompanied with hypoproteinemia are more likely to have inflammation complications and cardiovascular diseases,which should cause more attention on their malnutrition-inflammation- CVD(MIA)syndrome diagnosis and treatment.

Objective To determine and evaluate the method of localization of anal verge by mutislice spiral CT. To provide an imaging reference for operative guidance of low-rectal cancer. Methods Forty eight consecutive adult patients suspected of abnormalities other than rectal disease were evaluated with abdominal and pelvic CT scans since August, 2009. They were divided into two groups based on sex and age. There were 23 men and 25 women. The ages of young group were 28 to 50 years and the average age was 41 years. The ages of elderly group were 52 to 81 years and the average age was 64 years. A small cotton ball dipped with contrast media was put at the anal verge as a marker and CT scans were performed with 64-slice spiral CT scanner. The distances between the cotton balls and the lower margin of the pubis combination (La), the lower margin of the 5th sacral vertebra (Lb), the inferior aperture of minor pelvis(Lc) and the lower margin of the basement of external anal sphincter (Ld) were measured on the midsagittal images obtained by MPR. The averages, the standard deviations(s), the 95% and 80% confidence intervals of La, Lb, Lc and Ld were calculated. We took the intervals of ± 1.96 s or ± 1.28 s ＜ 5 mm as the standard of meeting the clinical requirement. The distances meeting the clinical requirement between different sex groups or age groups were compared with t test. Results The Ld was (9.8 ± 1.2) mm, ofwhich intervals of ± 1.96 s and ± 1.28 s were 4. 8 mm and 3.0 mm respectively, meeting the clinical need.This distance was also measured conveniently. There were no significant differences ( P ＞ 0.05 ) between two different sex groups [ male group, ( 10.0 ± 1.2) mm], female group, (9.6 ± 1.2) mm and between two age groups [ young group, (9.6 ± 1.2) mm, elderly group, ( 9.9 ± 1.3 ) mm ]. Conclusions The lower margin of the basement of external anal sphincter was a useful anatomic lanmark for localizing the anal verge,and could be definitely identified on the middle sagittal pelvic CT image. The distance between the structure and anal verge is constant enough and can be used in measuring distance from low rectal lesion to the anal verge.

The paper introduces storage ways of medical record information with both advantages and disadvantages, including data-base way, portfolio in order way, XML way, and the combination between XML and database. Comparison says that the combined way is the better way which harmonizes the structure and retrieval efficiency.

Adopting the theory of group fairness strategy put forward by Lawrence Kohlberg,an integrity education aimed at medical students is carried out on the basis of class,with teachers,family members and social individuals as cooperators.The integrity education could be promoted by setting up an independent nature,and educational idea of selective moral personality.It puts the core content of impartial democratic participation into effect,takes the morality sense of responsibility education as basis,constructs a democratic participation atmosphere,and emphasizes the significance of daily life during the integrity education in order to promote the cultivation of integrity quality of medical students.
