Hyperglycemia is a common complication of critical patients. Currently, clinical assessment of the changes in the blood glucose of critical patients is mainly based on the intermittent monitoring of peripheral blood glucose at a certain time point. This method cannot get the true blood glucose fluctuation, and it is more difficult to find asymptomatic hyperglycemia and hypoglycemia, so the guiding value of blood glucose control is limited. Arterial blood is the most accurate sample of blood glucose monitoring, so it is urgent to ensure the accuracy of arterial blood sample. A continuous arterial blood glucose monitoring equipment was independently developed by general surgical intensive care unit (ICU) of the First Affiliated Hospital of Nanjing Medical University, and National Utility Model Patent of China was obtained. It could greatly improve the efficiency of medical staff, and provide accurate and dynamic statistic data that would be an important basis for doctors' clinical decision-making. The continuous arterial blood glucose monitoring equipment was mainly composed of arterial pressure measuring monitor, program-controlled dynamic blood glucose meter, wire, electric switch, integrated collecting syringe, electric clip, rotary electric bracket, and blood glucose test strips, etc., which could be continuously and dynamically monitor patient blood glucose levels and perform various additional value-added functions such as automatic recording and alarming.

OBJECTIVE:To analyze the results of national evaluation inspection for 83 batches of Compound jiegeng mahuangjian syrup(Ⅱ)from 4 manufacturers,and to evaluate their quality. METHODS:Legal inspection method and exploratory research were adopted to test,analyze and evaluate sample statistically. The contents of exploratory research included HPLC method was used to determine the contents of preservative benzoic acid and ephedrine hydrochloride;antibacterial efficacy examination of formulation was studied;pH value of solution was determined;the content of sucrose was determined by polarimetry photometry;the relationship of the content of ammonium chloride with microbial contamination was studied;headspace GC method was used to determine the contents of menthol and ethanol;Platycodon grandiflorum extractum was identified and studied by TLC. RESULTS:Results of legal inspection showed that among 83 batches of sample,80 batches were qualified and 3 batches were unqualified,with qualified rate of 96.4%. Unqualified items were loading capacity,microbial limit and content ofammonium chloride,content of ammonium chloride. The results of legal test combined with exploratory research showed thatantibacterial efficacy of formulation of one manufacturer was not in accordance with the regulations;Some raw materials were notfed according to formulation, and the quality of products was not even. It is recommended to revise the quality standard:identificatied the Campanulaceae by TLC; determination the pH, preservative content, menthol content; revision ephedrinehydrochloride assay method to HPLC. CONCLUSIONS:The overall quality of Compound jiegeng mahuangjian syrup(Ⅱ)is notsatisfactory;there is a big flaw in the production process and quality control of some manufacturers;quality standards needed to beimproved.

Objective To study the histone acetylation level of CD4+ T cells in peripheral blood of lupus nephritis ,to explore the role of histone acetylation in pathogenesis of lupus nephritis .Methods According to Feng X ,Bernstein ,Wagner S J and other scholars′s classification criteria for LN ,those who met the following conditions considered for the activity of LN :proteinuria >0 .5 g/d ,change or activity of urinary sediment (hematuria > 5 red blood cell /Hp ,or pyuria > 5 Hp white blood cells ,or 1 cell type/Hp) ,serum creatinine increased >1 .2 mg/L ,and the exclusion of infection ,kidney stones and other causes .Lupus nephritis pa‐tients were divided into inactive group (group I) 8 people ,active group (group A) 10 people .18 patients with LN and 8 normal con‐trols were collected peripheral blood 50 mL ,density gradient centrifugation method (Ficoll method) for separation of mononuclear cells in peripheral blood;CD4+ T cell was analyzed by immunomagnetic beads ,extracted histone acetylation level and detected H3/H4 protein by the acetylation of histone H3/H4 kits and the relationship of histone H3/H4 acetylation with diseases was analyzed . Results First ,compared with group N ,the histone H3 and H4 of CD4+ T cells in peripheral blood both in A and I of group LN pa‐tients showed low acetylation status (P0 .05) .Third ,it was nega‐tively related to the acetylation level of histone H4 and 24 h urinary protein excretion(r= -0 .661 ,P<0 .05) .Conclusion Histone H3 and histone H4 of the CD4+ T cells showed low acetylation may be involved in the pathogenesis of lupus nephritis .The acetyla‐tion level of histone H4 in CD4+ T cells may be related to the activity of the LN .

Objective To study the role of nitiric oxide (NO) in the liver ischemic precondition (IP) in rats. Methods 131 rats were randomly assigned to ischemia/reperfusion (I/R)group, IP group and sham-operation(S) group. The plasma NO, alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the pathological change of liver and rat mortality were observed at 2 hours, 24 hours and 1 week after operation. Results (1) The plasma NO level grew soon after operation in group IP, and was significantly higher than that in group S in all three time points (P0.05), and higher at 1 week (P
