Objective To summarize the treatment experience of supraventricular tachycardia (SVT) after coronary artery bypass graft (CABG). Methods The clinical data of 136 patients who had occurred SVT after CABG between January 2008 and December 2009 were analyzed retrospectively. Results Among 136 patients,no perioperative mortality,atrial fibrillation (AF) occurred in 110 cases (80.88%),paroxysmal supraventricular tachycardia (PSVT) occurred in18 cases ( 13.24% ), atrial flutter occurred in 8 cases (5.88%),112 of 136 cases occurred in 1-3 days after surgery,accounting for 82.35% ,24 cases occurred in 4-7 days after surgery,accounting for 17.65%. Given amiodarone in the treatment of 105 cases,100 cases reverted to sinus rhythm (cardioversion rate of 95.24% ),given esmolol in the treatment of 11 cases, 9 cases reverted to sinus rhythm( cardioversion rate of 81.82% ), synchronous direct current cardioversion in 20 cases, all transferred to sinus rhythm, all patients with improved symptoms. The remaining failed to transfer to sinus rhythm, had got normal ventricular rate, and symptoms improved significantly. Conclusions It is necessary to take effective measures to prevent SVT within 3 days after CABG. Amiodarone, esmolol and synchronous direct current cardioversion can be used effectively and safely to control SVT after CABG.

BACKGROUND: Whether antihypertesive remedy is given or not is not only according to the blood pressure grade, but also to its risk stratification. Recently the relation of syndrome types to hypertension grades and risk stratification in primary hypertension has been investigated at home. OBJECTIVE: To observe the relation of syndrome types to hypertension grades and risk stratification in primary hypertension by the method of syndrome differentiation in traditional Chinese medicine combining with achievements in modern medicine. DESIGN: Descriptive investigation. SETTING: Department of Traditional Chinese Medicine, Jing'an District Central Hospital of Shanghai City and Shanghai Dahua Hospital. PARTICIPANTS: Sixty-four patients, in different genders and ages, with primary hypertension from Department of Traditional Chinese Medicine of Jing'an District Central Hospital of Shanghai City METHODS: The primary hypertension was classified into four types of syndrome: up disturbing of wind-yang, up clouding of turbid phlegm, deficiency of qi and blood and yin deficiency of liver and kidney. The relation of syndrome type to hypertension grade and risk stratification in primary hypertension was investigated combining syndrome differentiation in traditional Chinese medicine (TCM) and disease differentiation in Western Medicine. MAIN OUTCOME MEASURES: The relation of syndrome types to the age, course, blood pressure grade and risk stratification in primary hypertension RESULTS: All 64 patients entered the result analysis. ① Relationship of syndrome type with the age, course and blood pressure grade: The age of patients in up-disturbing of wind-yang group was younger than those in both up-clouding of turbid phlegm and yin deficiency of liver and kidney groups [(59.0±10.9), (72.7±9.1), (71.6±10.1)years, P ＜ 0.01]; the disease course of patients in yin deficiency of liver and kidney group was longer than those in up-disturbing of wind-yang group and up-clouding of turbid phlegm group [( 160.50±143.51 ), (64.83±70.77), (80.56±108.69)months,P ＜ 0.05];the difference of systolic pressure among different syndrome types was not significant, but the diastolic pressure in up-disturbing of wind-yang group was higher than those in other groups [(99±8), (92±9),(89±11 ), (89±12)mmHg, P ＜ 0.05]. ② The relationship of syndrome type with blood pressure grade and risk stratification: The difference of blood pressure grades among patients with different syndrome types was not significant, but the risk stratification in up-disturbing of wind-yang group was lower than those in up-clouding of turbid phlegm and yin deficiency of liver and kidney groups (There were respectively 3, 7, 5 and 3 cases; 15, 1, 1and 1 cases; 16, 1, 2 and 1 cases at very high risk, high risk, medium risk and low risk, P ＜ 0.05). CONCLUSION: Different syndrome types in TCM may present differences in hypertension grade and risk stratification, which can provide basis for determining therapeutic principle.

Objective To compare the mast cells' property and the level of pelvic pain, urgency and frequency (PUF) scale in urinary bladder between interstitial cystitis (IC) patients and controls.Methods Eighteen cystoscopy biopsy specimens of interstitial cystitis patients and 12 controls were stained with 0.5% toluidine blue and immobilizated with Osmic Acid. Then the mast cells were observed and counted with light microscope and transmission electron microscope. The PUF scale and the number of mast cells between the 2 groups were compared. Results The mast cell's number of the interstitial cystitis samples(28-76 pieces/mm2) was significantly higher than that of the non IC persons' bladder tissues(7-15 pieces/mm2) (Z=3.927,P＜0.01). 75.3% mast cells were in a state of being activated degranulation. The PUF scale of IC patients( 17-35 scores)was significantly higher than that of the non IC persons' (0-8 scores) (t=14.736,P＜0.01). The PUF scale of the patient group did not have a linear IC relation with the mast cell's infiltrated number among the specimens (rs=-0.618,P=0.601). Conclusions Mast cell infiltration may be one of the characteristic pathological manifestations of IC. The association of mast cell infiltration and the PUF scale may be a new diagnosis criteria for IC.

Glycerol is the main byproduct in ethanol production by Saccharomyces cerevisiae. In order to improve ethanol yield and the substrate conversion, a cassette about 4.5 kb for gene homologous recombination, gpd2Δ::PGK1(PT)-POS5-HyBR, was constructed and transformed into the haploid strain S. cerevisiae S1 (MATa) to replace the GPD2 gene by POS5 gene. The NADH kinase gene POS5 was successfully over expressed in the recombinant strain S. cerevisiae S3. Comparing with the parent strain, the recombinant strain S. cerevisiae S3 exhibited an 8% increase in ethanol production and a 33.64% decrease in glycerol production in the conical flask fermentation with an initiatory glucose concentration of 150 g/L. Overexpression of NADH kinase gene seems effective in reducing glycerol production and increasing ethanol yield.

Objective To study the expression of lectin-like oxidized LDL receptor-1 (LOX-1) protein in acute lung injury (ALI) and the effect of captopril on this expression in order to investigate its role in the process and preliminary intervention.Methods Sprague-Dawley rats were randomly divided into 3 groups,normal control group,lipopolysaccharide (LPS) groups,and a LPS+captopril group,each group 10 rats.ALI model was induced by intratracheal injection of LPS (5 mg/kg),then those of LPS+captopril group were give an intraperitoneal injection of captopril (1.25 mg/kg).The animals of normal control group received an intratracheal injection of normal saline.In 6 h after LPS injection,the level of p(O2),wet/dry ratio (W/D),concentration of total protein in bronchoalveolar lavage fluid (BALF) and lung tissue histopathological changes were examined.The expression of LOX-1 protein in the lung tissue was measured by Western blot analysis.HE staining was used to examine the pathological changes of the lung.Results Histological examination showed that extensive lung inflammation were seen in the LPS group,which manifested by accumulation of significant numbers of neutrophils.The level of p(O2) in LPS group [(6.86?0.75) kPa] was decreased compared with that in sham group [(12.14?0.60) kPa,P

The respective sense and antisense oligodeoxynucleotides and their phosphorothiods, targeting at the bcr/abl, were the hallmark gene of Chronic Myelogenous Leukemia( CML) and c-myb correlates with CML. K562 cells, derived initially from a patient of CML blast crisis, were incubated with bcr/abl antisense oligodeoxynucleotides asODN or c-myb asODN or with both asODN in combinalion. All kinds of asODN could not only significantly inhibit K562 cells survival with the highest inhibitory rate of 64.7%?3.2%, but also dramatically inhibit DNA synthesis and the highest inhibitory rate was 85. 8 %?4.1%, decrease bcr/abl mRNA level almost completely and induce apoptosis significantly. The inhibition effect of antisense oligodeoxynucleotides phosphorothiodes s-asODN was stronger than that of unmodified asODN. The inhibition of the combination of bcr/abl and c-myb asODN was stronger than that of anyone alnoe. All the inhibitions exhibited in sequence-and time-dependent manner. We concluded that bcr/abl in pathogenesis of CML not only increased CML cells proliferation rate, but also decreased CML cells apoptosis rate. c-myb may participate in CML mainly by regulating bcr/abl. Trie results indicated that the modified asODN and multiple asODN targeting several oncogenes may advance to antisense gene therapy.

Objective This study examined the effects of Midazolum-ketamine oral solution (MKOS) on the expression of N-methyl-D-aspartate receptor 1 (NMDAR1) and gamma-aminobutyric acid (GABA)A receptors (GABAAR) mRNA in the cerebral cortex of rat, in order to investigate the sedation mechanism of MKOS. Methods Fifty Sprague-Dawley(SD) rats were divided into ten groups according to the observed time after MKOS administration (0,5,10, 15,30,60,90,120,240 and 360 minutes, n =5 each). The 0 minute group(control group) received 0.9% saline instead. Immunohistochemical staining and in situ hybridization were used to detect the expressions of NMDAR1 and GABAAR mRNA in the cerebral cortex. Results Both GABAAR and NMDAR1 all expressed in the glial cells of cerebral cortex. The expression of NMDAR1 in control group was strong. The expression of NMDAR1 became weaker during 15 to 90 minutes after administration of MKOS (P＜0.05). The expression of GABAAR mRNA in control group was weaker,while became stronger during 30 to 90 minutes after administration of MKOS (P ＜0. 05). Conclusion MKOS may play sedation by strengthening the expression of GABAAR and suppressing the expression of NMDAR1 in the cerebral cortex.

Objective To investigate the change in natural kill cell,T-ly mphocyte subset counts and effect of recovery after homologous and autologous blood transfusion.Methods 50 patients undergoing lung cancer operation were randomly divided into two groups:group A received autologous blood transfusion with 400ml and group H received homologous blood transfusion with 400ml.Venous blood samples were taken before surgery,before blood transfusion and on the 1st and 5th postoperative day for determination of T-ly mphocyte subsets and natural kill cell counts by flow cytomet.The existent ratio of 1～3 years were followed up.Results The NK cell,CD+_3 and CD+_4 counts and CD+_4/CD+_8 ratio decreased significantly on the 1st postoperative day in both groups(P
