In traditional Chinese medicine herbs (TCM), including Radix Salviae Miltiorrhizae (Danshen), Radix Puerariae Lobatae (Gegen), Radix Angelicae Sinensis (Danggui), and Rhizoma Chuanxiong (Chuanxiong) are widely used for the prevention and treatment of cardiovascular diseases and also often co-administered with Western drugs as a part of integrative medicine practice. Carboxylesterase 1 (CES1) plays a pivotal role in the metabolisms of pro-drugs. Since (S)-2-(2-(6-dimethylamino)-benzothiazole)-4,5-dihydro-thiazole-4-carboxylate (NLMe) has recently been identified by us as a selective CES1 bioluminescent sensor, we developed a rapid method using this substrate for the direct measurement of CES1 activity in rats. This bioluminescence assay was applied to determine CES1 activity in rat tissues after a two-week oral administration of each of the four herbs noted above. The results demonstrated the presence of CES1 enzyme in rat blood and all tested tissues with much higher enzyme activity in the blood, liver, kidney and heart than that in the small intestine, spleen, lung, pancreas, brain and stomach. In addition, the four herbs showed tissue-specific effects on rat CES1 expression. Based on the CES1 biodistribution and its changes after treatment in rats, the possibility that Danshen, Gegen and Danggui might alter CES1 ac-tivities in human blood and kidney should be considered. In summary, a selective and sensitive biolu-minescence assay was developed to rapidly evaluate CES1 activity and the effects of orally administered TCMs in rats.

Objective:To study the risk factors of massive bleeding in patients with acute Stanford type A aortic dissection undergoing moderate hypothermic circulatory arrest repair.Methods:From January 2016 to October 2017, 486 consecutive patients with acute type A aortic dissection were included in the study. All operations were performed with moderate hypothermic circulatory arrest. The basic clinical data of patients were collected retrospectively. Massive bleeding was defined according to definition of Universal Definition of Perioperative Bleeding(UDPB) 4 class and the Blood Conservation Using Antifibrinolytics in a Randomized Trial(BART). Significant variables in univariate analysis were included in multivariate logistic regression analysis. Results:Thirty-four patients(7.00%) died in hospital. A total of one hundred and eighty-seven patients(38.48%) fulfilled criteria of the definition of BART massive bleeding. Forty-five patients(9.26%), 8 patients(1.65%), 114 patients(23.46%), 147 patients(30.25%) and 172 patients(35.39%) were in grade 0, grade 1, grade 2 and grade 4, respectively. With BART as the end point, the result of multivariate logistic regression showed that female gender( OR=3.32, P<0.001), anemia( OR=2.24, P=0.04), clearance creatine≤85 ml/min( OR=1.93, P=0.01), D-dimer level(every 500 ng/ml increase, OR=1.02, P=0.003), cardiopulmonary bypass(CPB) time( OR=1.01, P<0.001), total arch replacement(TAR, OR=2.40, P=0.02) were independent risk factors for massive bleeding, and the time from onset to operation( OR=0.86, P=0.01) was protective factor. With UDPB 4 class as the end point, multivariate logistic regression showed that creatinine clearance≤85 ml/min( OR=2.05, P=0.001), CPB time( OR=1.01, P=0.04) were independent risk factors for massive bleeding. The time from anset to operation( OR=0.85, P=0.002) and Bentall procedure( OR=0.65, P=0.04) were the protective factors. Conclusion:Massive bleeding was more common in acute Stanford type A aortic dissection. Female gender, poor preoperative renal function, high D-dimer level, early time accepting surgical operation and long CPB were independent risk factors. For high-risk patients, simple and effective surgical methods should be taken to reduce the risk of bleeding.

This study was purposed to investigate the inhibition of hTERT antisense oligodeoxynucleotide (ASODN) on the proliferation and telomerase activity in HL-60 cells and to explore the relativity between the telomerase activity and the expression of hTERT gene in HL-60 cells. After treated by hTERT ASODN the expression of hTERT was detected by RT-PCR, the morphological changes of HL-60 cells was observed with inverted microscopy, the cell proliferation was measured by MTT method, and the telomerase activity was determined with TRAP-ELISA and TRAP-PAGE. The results showed that after sealing hTERT gene with ASODN for 72 hours, the expression of hTERT gene was significantly inhibited, the cell growth was repressed and the ability of proliferation decreased, and the effect was specific in sequence and dependent in dose and time. OD(450-690) values were 2.648 +/- 0.42, 1.504 +/- 0.47, 1.223 +/- 0.39, 0.944 +/- 0.16 respectively, as the cells were treated with 0, 10, 20, 30 micromol/L ASODN for 72 hours. The difference was significant as compared 10, 20, 30 micromol/L groups with 0 micromol/L ASODN group respectively (P < 0.05), but the difference was no significant when compared 20 micromol/L SODN group (2.376 +/- 0.65) with untreated group (2.648 +/- 0.42) (P > 0.05). TRAP-PAGE detection revealed that comparing ASODN groups with SODN groups the telomerase image bands were decreased and least was found in groups of 30 +/- mol/L. It is concluded that the hTERT ASODN may inhibit the proliferation and down-regulate the telomerase activity in HL-60 cells by sealing the expression of hTERT gene.

OBJECTIVESince late March 2009, a novel influenza H1N1 strain emerged in humans in Mexico and the United States. It has rapidly spread to many countries on different continents, prompting unprecedented activation of pandemic preparedness plans. The present study aimed to investigate the characteristics of children with the novel influenza A (H1N1) virus infection.
METHODTwelve cases with influenza A (H1N1) infection were diagnosed according to the criteria of the Center for Disease Control and Prevention (CDC) of China during 1 May to 15 July 2009 in the Pediatric Hospital of Fudan University were analyzed. Influenza A (H1N1) RNA was detected by RT-PCR in CDC Shanghai China.
RESULTAll the 12 children with the novel influenza A (H1N1) virus infection were imported cases, aged from 11 months to 14 years 7 months, 7 of whom were boys, 5 were girls. Five cases contacted closely with influenza A (H1N1) patients; 12 cases had fever and no vomiting or diarrhea; 7 had cough or runny nose or anorexia. One had shortness of breath. Of the 11 cases who could tell about symptoms correctly, 6 had sore throat, 3 had stomachache, and none had muscle pain. Two of the 12 cases had pneumonia, and the disease in 1 of them was fatal and needed intensive care. One case was isolated and treated at home. The 11 cases hospitalized were treated according to the guidance of influenza A (H1N1) diagnosis and treatment issued by the Ministry of Health of China. Ten hospitalized cases were treated with oseltamivir. All the cases recovered completely. The median length of hospital stay was 8.1 days (range, 6 to 16), and the time of negative test results of influenza A (H1N1) RNA from illness onset to collection of samples for viral testing was from 5 to 15 days.
CONCLUSIONSymptoms among children with the novel influenza A (H1N1) virus infection were classic and the majority of the cases we treated had a mild clinical course if they were isolated and treated promptly. Antivirals appears to have not had any major adverse effects. More data from different regions and large samples are needed to illuminate the characteristics of children with novel influenza A (H1N1) virus infection.
