Objective To study the significance of serum ischemia modified albumin(IMA) and brain natriuretic peptide(BNP) in patients with acute coronary syndrome. Methods Patients with acute coronary syndrome in six hours were divided into ST elevation myocardial infarction(STEM) of forty one cases, non-ST elevation myocardial infarction( NSTEM)of forty four cases and unstable angina of forty three cases. Twenty healthy people were selected as the control group. The serum IMA and BNP were detected. Results The levels of IMA and BNP in STEM group [(89. 6 ± 21.4) ABSU/ml, ( 324. 6 ± 39. 1 ) ng/L] were significantly higher than those in NSTEM group [( 79. 3 ±20. 5) ABSU/ml, (259. 7 ± 30. 5) ng/L]. The levels of IMA and BNP in NSTEM group were significantly higher than those in UA group[(67. 1 ± 18. 3)ABSU/ml,(124. 1 ±24. 3)ng/L].The levels of IMA and BNP in UA group were significantly higher than those in control group [( 56. 2 ± 15. 1 ) ABSU/ml, ( 15.9 ± 6. 7 ) ng/L]. Conclusion The levels of IMA and BNP in serum could forecast severity in patients with acute coronary syndrome.

According to clinical epidemiological researches, the usage of antibiotics in infant increases the risk of childhood asthma morbidity. The mechanism of this link is not entirely clariifed, and it is assumed of being related to side effects of antibiotics, which changes the colonization of normal intestinal lfora and reduces the diversity. It is clear that normal intestinal lfora of infant help to construct innate immune system and adaptive immune system, and forge immune tolerance. Therefore, normal intestinal lfora might be helpful in reducing allergies. The usage of antibiotics in early life changes the quantity and the composition of intestinal lfora, and breaks the balance of immune homeostasis, which might increase the risk of asthma morbidity. The abuse of antibiotics in children is a general phenomenon in China which needs attention from pediatricians.

BACKGROUND:The research for mesenchymal stem cels in the treatment of liver cirrhosis has made great progress. However,t-test analysis is often misused in clinical practice. OBJECTIVE:To analyze the efficacy and safety of umbilical cord mesenchymal stem cel therapy for liver cirrhosis by repeated measurement method. METHODS: A total of 27 patients with decompensated liver cirrhosis underwent conventional medical treatments, including liver protection treatment and symptomatic treatment. At 1 week after hospitalization, patients were given intravenous transplantation of umbilical cord mesenchymal stem cels (passages 2-4), cel viability≥ 90%, stem cel counting≥ 2×107 cels, four times with an interval of 5-7 days. Analysis of variance based on repeated measurement data was performed to analyze the liver function changes at different time after umbilical cord mesenchymal stem cel transplantation. RESULTS AND CONCLUSION: The results of univariate repeated measurement showed that at 2 and 3 months after treatment, the serum albumin level was increased and the total bilirubin level in serum was decreased significantly (P < 0.05); at 3 months after treatment, the content of aspartate aminotransferase decreased, and the content of cholinesterase increased significantly (P < 0.05). No patient appeared to have liver and other organ tumors during the observation period. These findings indicate that umbilical cord mesenchymal stem cel transplantation is effective and safe in the treatment of liver cirrhosis, which can significantly improve patient's liver functions.

[ABSTRACT]AIM:TodeterminetheeffectsofShensongyangxincapsule(SSYX)ontheventricularelectrical properties, structural remodeling and cardiac function in the rats with diabetes mellitus (DM).METHODS:Male SD rats (n=45) were randomly divided into control group (n=15), DM group (n=15) and SSYX group (n=15).The rats in DM group and SSYX group were injected with streptozotocin (60 mg/kg, ip), while the rats in control group were given normal saline (1 mL/kg, ip).The blood samples were collected 72 h after treatment for determining the blood glucose lev-els in DM group and SSYX group .The model rats in SSYX group were administered with SSYX (1 g· kg-1 · d-1 , ig) for 6 weeks, while the other rats received normal saline (2 mL· kg-1· d-1, ig).The echocardiography was used to assess the cardiac function , and the lead II electrocardiogram was also recorded in all the animals .The radioimmunoassay and Masson trichrome staining were used to measure the plasma levels of endothelin -1 (ET-1) and the collagen deposition in the ventricles, respectively.A whole Langendorff-perfused heart model was used to conduct the electrophysiologic study .The monophasic action potential ( MAP) and the ventricular effective refractory period ( VERP) were recorded in the left anteri-or free wall ( LAF) , and the burst pacing was used to induce ventricular arrhythmia ( VA) .RESULTS: Compared with control group, the VERP, action potential duration (APD), QT interval, incidence of VA, degree of myocardial fibrosis and plasma level of ET-1 were increased , while the cardiac function was declined in DM group .Compared with DM group , the VERP, APD, QT interval, incidence of VA, degree of myocardial fibrosis and plasma level of ET-1 were all de-creased, while the cardiac function was improved in SSYX group .CONCLUSION: SSYX attenuates the electrical and structural remodeling and improves the cardiac function in DM rats .

BACKGROUND:The precise pathogenesis of recurrent aphthous ulcers remains controversial in present medical science. Oxygen free radical increase in the body is one of the causes of recurrent aphthous ulcers. OBJECTIVE:To observe the effects of superoxide dismutase on the therapeutic effect of recurrent aphthous ulcers. METHODS:After establishing 24 rabbit models of recurrent aphthous ulcers, they were randomly assigned to three groups. Model control group as a contrast was not treated. Rabbits in the negative control group were cleaned with iodoglycerin in local region daily. Rabbits in the superoxide dismutase group were intragastricaly administered with superoxide dismutase capsule solution. Local ulcer was cleaned with iodoglycerin. One week later, tissue with oral ulcer lesions was obtained and compared. In each group, after model establishment, blood was colected from rabbit ear vein at the same time in the morning every 4 days. Flow cytometry was used to analyze the changes in T cel subsets CD3+, CD4+, CD8+, and CD3+/CD8+. RESULTS AND CONCLUSION: When the ulcer lesions formed, peripheral blood CD3+, CD4+, CD4+/CD8+ ratio through statistics was apparently lower than normal levels in the model control group and negative control group. However, the number of CD8+ cels was greatly more than normal value. In the superoxide dismutase group, after administrated with superoxide dismutase capsule, the number of CD3+ and CD4+ cels was gradualy increased, but the number of CD8+ cels showed a decreased trend. These data suggested that natural scavenger superoxide dismutase using oxygen free radical can effectively scavenge excessive oxygen free radical in the ulcers, resulting in treatment of recurrent aphthous ulcers.

Objective To investigate the selection and curative effect of surgical approach for thoracolumbar fractures. Methods A retrospective analysis was conducted on 212 patients with thoracolumbar fractures treated surgically from January 1995 to January 2009 to observe the spinal column and the neurological function recovery. Results Anterior surgery was performed in 73 patients and posterior surgery in 139. The patients were followed up for average 23.7 months ( range, 12-52 months). The height of injury vertebral, the Cobb' s angle and the volume of vertebral canal were improved significantly (P <0.01 ). The patients with incomplete paralysis all got nerve function recovery at different extents ( from one grade to three grades). Conclusions Surgical treatment for thoracolumbar fractures can effectively recover the spine structure and promote the nerve function recovery. The surgical approach should be selected based on the fracture type.

Objective To evaluate the therapeutic efficacy of congenital muscular torticollis (CMT) by two different methods. Methods A total of 86 patients with congenital muscular torticollis in recent 7 years were involved in this study, including 69 cases under 12 years old and 17 cases over 12. Two different operation methods, incision of inferior extremity of sternocleidomastoid muscle and incision of amphi-sternocleidomastoid muscle with post-operative traction, were alternatively chosen according to the ages and deformed degrees of the patients. Results 72 patients were followed-up for 1 to 7 years (averaged 4.5 years). Based on the effect of function and cosmetology in the group of 57 cases under 12 years old, there were 52 cases (91.2 %) excellent, 5 cases (8.8 %) good and no case with side-effects. Meanwhile, in the group of 15 cases over 12 years old, there were 11 cases (73.3 %) excellent, 4 cases (26.7 %) good and no case with side-effects. The effect was satisfactory. Conclusion Different patients with congenital muscular torticollis should be treated with different therapeutic methods.
