ABSTRACT
Objective To discuss the diagnostic value of detecting plasma vitamin B12 and Homocysteine (Hcy) in subacute combined degeneration of the spinal cord (SCD).Methods Parents of SCD (n=29) and subjects (n=74) without spinal cord diseases were enrolled from the clinic of Shaanxi Provincial People's Hospital from April 2014 to July 2016.The plasma vitamin B12 and Hcy concentrations were detected using Chemiluminescence Immunoassay (CLIA) and enzyme-linked immuno sorbent assay (ELISA) respectively,and compared using chi-square between the SCD and control groups.Sensitivity rate,specific rate,and diagnose accordance rate were evaluated.Results The plasma homocysteine and vitamin B12 concentrations in SCD and control groups were 49.41 μmol/L vs 12.36 μmol/L,44.35 pg/ml vs 166.75 pg/ml,with significant differences (U=343.50,800.00,P＜0.05).Negative correlation existed between the concentrations of vitamin B12 and Hey (r=-0.248,P=0.012).The sensitivity rates of vitamin B12 and Hcy detections were 55.2％ vs 89.7％,which had significant differences (x2 =8.631,P=0.003),and the diagnose accordance rate (69.9％ vs 64.1％) of the former was higher (x2 =4.175,P=0.041).Conclusion The plasma Hcy and vitamin B12 concentration detections had definite diagnostic value in SCD,and Hcy had higher sensitive rate,which can improve the diagnostic rate of SCD in the early stage.
ABSTRACT
Objective To investigate the relationship between the the expression of SOCS-1/3 in the peripheral blood mononuclear cells (PBMCs) and interferon therapeutic response in patients with chronic hepatitis B.Methods 50 patients with chronic hepatitis B were given interferon therapy.After 24 weeks treatment,according to biochemical and virologic response,they were divided into two groups:response and non response group.HBV-DNA was detected by PCR.The SOCS-1/3 mRNA levels were measured by RT-PCR.Results The expression of SOCS-1 in the PBMCs of response group after 24 weeks treatment was significantly higher than that before interferon therapy (P ＜ 0.05).The expression of SOCS-3 in the PBMCs of response group after 24 weeks trentment was significantly lower than that before interferon therapy (P ＜ 0.05).In non response group,there were no significant differences in the expression of SOCS-1/3 (P ＞ 0.05).Conclusion The increase expression of SOCS-1 mRNA and the decrease of SOCS-3 mRNA in the PBMCs in chronic hepatitis B patients received 24 weeks interferon-therapy probably is relevant to the IFN-α antiviral effect.

ABSTRACT
Objective The aim of this study was to determine the effect of a new method of cardiac assistant therapy with an extra-aortic balloon pump on the experimental dogs in which myocardial ischemia or infarction were induced, and to ob serve its effectiveness and feasibility. Methods Twelve animal models of myocardia 1 infarction were established with the method of left anterior descending coronary artery ligation. They were divided randomly into two groups, six in the experimental group and six in the untreated group. The end points observed were the differences between the two groups in the blood pressure, cardiac function, myocardial enzymes, infarction size and routine blood variables before procedure, 1,2, 3, 4, 5 and 6 hours after myocardial infarction. Results All six dogs in the experimental group were survived, with a mortality rate of 0.The number of death in the control group was three, with a mortality rate of 50%. Measurements such as mean blood pressure,cardiac output, cardiac index in the experimental group were better than those in the control group ( P ＜ 0.05 ). Mean heart rate before myocardial infarction in the experimental group was 156 beats per minute, as compared with 148 beats per minute in the control group, and was 128 vs. 67 beats per minute respectively six hours after myocardial infarction. The cardiac output was 3.48 vs. 4.98 liters per minute before myocardial infarction and was 6.10 vs. 0.85 liters per minute six hours after myocardial infarction. The average pressure was 94 mm Hg vs. 99 mm Hg before myocardial infarction and was 70 mm Hg vs. 33 mm Hg six hours after myocardial infarction. Conclusion The extra-aortic balloon pump significantly improved the hemodynamic variables of the experimental animals after myocardial infarction and reduced mortality. Injury to the blood cells may be the potential disadvantage.
ABSTRACT
Objective To analyze the clinical characters in old patients undergoing coronary artery bypass grafting (CABG). Methods The clinical data of 426 patients undergoing CABG from January 2000 to April 2009 in our hospital were retrospectively analyzed. One hundred eighteen patients were 70-82 years old (older group), 308 patients were 24-69 years old (younger group). The perioperative risk factors, surgical complication and outcomes between the two groups were compared.Results The older group had higher incidences of post-operative complications than younger group.Pre-operative risk factors included the female, chronic obstructive pulmonary disease, peripheral vessel disease, New york heart association(NYHA) class Ⅳ, unstable angina requiring intravenous nitrates until arrival in the anaesthetic room, left ventricular ejection fraction ＜30%. The older group showed higher incidences of postoperative severe complication, operative mortality, and more grafts and longer time in intensive care unit (ICU), and had lower incidents of valve disease and less use of left internal mammary artery [16 patients (13. 6%) vs. 152 patients (49.4%), all P＜0. 05].Conclusions The many CABG risk factors in China are different from those in the western countries.Although the higher incidents of postoperative severe complication and higher operative mortality are found in the older patients, the recovery period after operation isn't obviously prolonged. The operative outcomes are satisfactory.

ABSTRACT
Objective The purpose of this study was to discuss the effect of visible light therapeutic equipment accompanied with electrolyzed-oxiding water (EOW) on pressure ulcer above the second phase. Methods We divided 44 patients with pressure ulcer above the second phase into the test group (23 cases, 28 spots) and the control group (21 cases, 25 spots). The test group received local decompression, debridement with EOW, exposure to visible light for 20 minutes, 10 times per day. The control group adopted local decompression, debridement with normal saline and local application of burn cream, 3 times per day. Results The effective rate of the test group was apparently higher than that of the control group (P<0.05). The healing time was also shorter than that of the control group (P<0.01). Conclusion Treatment of pressure ulcer above the second phase with visible light therapeutic equipment accompanied with electrolyzed-oxiding water proved to be an effective treatment method.
