5.Effective radiation dose in cardiac interventional procedures: the difference between ICRP publication 60 and publication 103
Journal of Interventional Radiology 2009;18(12):923-926
Objective to compare the calculated effective radiation dose variations in cardiac interventional procedures of coronary angiography (CAG) and percutaneous transluminal coronary angioplasty (PCI) by using the different tissue weighting factors recommended by ICRP Publication 60 with that recommended by ICRP Publication 103. Methods Measurements of organ doses were carried out with an anthropomorphic phantom equipped with thermoluminecent dosimetry. The effective radiation doses were separately calculated using the tissue weighting factors provided by ICRP 60 and provided by ICRP 103, and the results obtained from ICRP 60 were compared with that obtained from ICRP 103. Conversion factors of effective, radiation dose to dose area product (DAP) were also calculated according to different publication.Results The variations in the effective dose were 6.88% for CAG and 8.46% for PCI. The effective dose variations in CAG and PCI were. 7.25% and 8.76% for female and were 6.51% and 8.17% for male,respectively. The effective conversion factors of DAP were. 0.10 ~ 0.11 and 0.13 ~ 0.14 for CAG and PCI,respectively, according to ICRP 60 and 103. Conclusion The variation of conversion factors of effective dose indicates that in making estimation of effective radiation dose. by using the widely accepted conversion factors, the adjustment of organ weighting factors recommended by ICRP 103 should be considered.
6.Interpretation of the third universal definition of myocardial infarction
Chinese Journal of Laboratory Medicine 2013;(6):485-488
Myocardial infarction (MI) is a major cause of death and disability worldwide.The definition of myocardial infarction has been updated.Released in 2012,Third Universal Definition of Myocardial Infarction of ESC/ACCF/AHA/WHF Expert Consensus,made the clinical application value of troponin clear and suggested to monitor the dynamic changes of cTn in patients with suspected,emphasized the importance of clinical differential diagnosis.In consensus,it also noted that the application of high sensitive troponin can lead to false positives results,and pointeds out that in the assessment of cardiac injury associated with percutaneous or surgical coronary procedures,the rational cut-off value of cTn remains controversival.In addition to acute coronary syndrome,cTn elevations are common in many disease states,and with the improvement of detection sensitivity,low level increase of cTn,will be more.In acute and chronic heart failure,the cTn is elevated,and ACS may be the cause of worsening heart failure,So we should identify whether the cTn elevation is pure from the myocardial injury of heart failure or myocardial necrosis caused by ACS.Nowadays,the increased incidence of myocardial infarction has much to do with the wide application of cTn.Clinical applications of cardiac biomarkers and imaging techniques are flexible as the differences in the diagnostic techniques of myocardial infarction among countries and regions result.
7.Effects of NTI-tss splint in the treatment of myofascial pain dysfunction syndrome
Journal of Practical Stomatology 2014;(2):273-275
20 patients with myofascial pain dysfunction syndrome(MPDS)were were treated by NTI-tss splint only during night for 2 months.After treatment,VAS decreased(P <0.01)and active maximum mouth opening degree increased(P <0.01).NTI-tss splint is ef-fective in the treatment of MPDS.Its side effect needs to be further observed.
8.Retrospective Analysis of Zhu Yun Pill in Treating 133 Cases of Infertility due to LPD
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
Objective: To investigate the effects of Zhu Yun Pill(ZYP) in the treatment of infertility due to luteal phase defect(LPD).Methods: 163 infertility patients due to LPD were randomly divided into three groups in terms of ZYP group,progesterone group and combination group(ZYP and progesterone).Then the therapeutic efficacy was judged by the pregnancy rate(PR),endometrial biopsy,the level of serum hormone and basal body temperature before and after the treatment.Result: 40 women were pregnant in ZYP group(cure rate,33.33%),8 in the progesterone group(cure rate,26.67%) and 9 in the combination group(cure rate, 69.23%).The symptomatic amelioration and total effective rate of ZYP group were obviously higher than single exogenous progesterone group(P

Bovine Lactoferricin is a fragment of polypeptide which derives from N-terminal of bovine lactoferrin when it is digested by pepsin in acid condition. It has many biological functions. This study was designed to research the antibiosis spectrum of LfcinB and the key functional active site of the LfcinB by amino acid substitution and peptide sequence modification. Antimicrobial spectrum of the artificial synthesized LfcinB was determined by agar-well diffusion method. The antibacterial active sites were confirmed by minimal inhibitory concentration assays. After the Cysteine at the third site and the tryptophan at the eighth site of LfcinB were substituted by alanine, or two cysteine of LfcinB were respectively, the minimal inhibitory concentration of the three artificially modified LfcinBs was assayed. Results showed that LfcinB had a broad-spectrum of antibiosis, it could restrain various bacterials, such as Gram-positive bacteria, Gram-negative bacteria, fungus and mycetes. LfcinB was stable to heat and pH, it could not be inactivated by many protease. The tryptophan at the eighth site and the intramolecular disulfide bond formed between two cysteins played a key role for antibiosis, as the functional active sites of LfcinB.
10.Clinical Observation of Intensive Rosuvastatin Therapy in the Treatment of Acute Coronary Syndrome
China Pharmacy 2017;28(11):1510-1513
OBJECTIVE:To observe long-term efficacy of intensive rosuvastatin therapy in the treatment of acute coronary syn-drome (ACS) and explore its possible mechanism,so as to provide reference for clinical diagnosis and treatment. METHODS:ACS patients receiving rosuvastatin after cured in our hospital during Jan. 2013-Jan. 2015 were divided into observation group(55 cases)and control group(47 cases)according to the dose of rosuvastatin. Under same guidance of physicans,2 groups were addi-tionally given Rosuvastatin calcium tablets(20 mg for observation group,10 mg for control group,qd,po)orally on the basis of routine treatment. Both groups were treated for 1 year. The incidence of 1-year accumulative main adverse cardiac event (MACE) were compared between 2 groups as well as the levels of blood lipid and serum cytokines,the occurrence of ADR before treat-ment,after 3 months of treatment. RESULTS:The incidence of accumulative MACE in observation group was significantly lower than control group,with statistical significance (P<0.05). After treatment,the levels of TC and LDL-C in 2 groups were de-creased significantly;the level of LDL-C was inCreased significantly compared to before treatment,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The levels of IL-1β and TNF-α in 2 groups were decreased significantly (P<0.05);the observation group was significantly lower than the control group,with statistical signifi-cance (P<0.05). The peripheral blood LDL-C was positively correlated with IL-1β and TNF-α in observation group after treat-ment,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Intensive rosuvastatin therapy can significantly improve the long-term prognosis for ACS patients,which may associate with lipid metabolic regulation and anti-inflammatory effect.
