Chinese Journal of Primary Medicine and Pharmacy 2015;(20):3132-3135
Objective To observe the clinical effect of card other tromethamine for postpartum hemorrhage. Methods 80 cases with postpartum hemorrhage were randomly divided into the observation group and control group, 40 cases in each group.The control group was given oxytocin treatment.While the observation group was given oxyto-cin and card other tromethamine treatment.The clinical curative effect,bleeding time after treatment,postpartum 2h haemorrhage amount and adverse reaction,etc.were observed and compared.Results The total effective rate of the observation group was 95.0%,which was significantly higher than 75.0% of the control group,the difference was sta-tistically significant(χ2 =15.68,P <0.05).The haemorrhage amount of postpartum 2h of the observation group was (273.7 ±10.5)mL,which was significantly lower than (547.1 ±16.4)mL of the control group,the difference was statistically significant(t =88.79,P <0.05).The bleeding time of the observation group was (14.8 ±3.4)min,which was significantly shorter than (34.9 ±8.4)min of the control group,the difference was statistically significant (t =14.02,P <0.05).The incidence rate of adverse reactions of the observation group was 7.5%,that of the control group was 5.0%,there was no statistically significant difference between the two groups(χ2 =0.53,P >0.05 ). Conclusion Card other tromethamine in the treatment of postpartum hemorrhage has good clinical curative effect and high safety.
5.Rituximab for the treatment of immune-mediated glomerular diseases
Journal of Medical Postgraduates 2015;(11):1204-1208
Rituximab ( RTX) is a monoclonal antibody to the CD 20 antigen on B-cells that was initially designed and approved for the treatment of non-Hodgkin′s B-cell lymphoma and has emerged as a potent immunosuppressant for many immune -mediated disea-ses.Given its efficacy , tolerability and safety profile in comparison to more conventional treatment regimens , RTX is rapidly emerging as a critical therapeutic modality for glomerular disease .The paper reviews the role of RTX in the treatment of ANCA-associated vascul-itis, lupus nephritis , mixed cryoglobulinemia , membranous nephropathy , minimal change disease , and focal segmental glomeruloscle-rosis.
6.Effect of Danshen injections on NT-proBNP in patients with hypertension and left ventricular failure
International Journal of Laboratory Medicine 2016;37(19):2728-2729
Objective To study the effect of Danshen injection on brain peptide type B (NT‐proBNP) in patients with hyperten‐sion and left ventricular failure ,provide an effective basis for clinical treatment .Methods Totally 80 patients of hypertension with left heart failure from February 2015 to February 2016 were randomly divided into two groups :40 patients were treated with con‐ventional therapy (control group ) ,40 patients in the conventional treatment combined with Danshen injection (experimental group) .We compared NT‐proBNP ,inflammatory factors and clinical efficacy between two groups .Results Before treatment ,the expression of NT‐proBNP and hs‐CRP ,NT‐proBNP level was basically the same in two groups (P> 0 .05) .After treatment ,the ex‐perimental group of patients with NT‐proBNP was significantly lower than the control group and the LVEF ,left ventricular mass index and left ventricular volume index were significantly higher compared with the control group (P< 0 .05) .The total effective rate of patients in Danshen injection groups was significantly higher (P< 0 .05) .Conclusion The injection of Danshen in patients with hypertension and heart failure patients can significantly improving NT‐proBNP levels and improve the cardiac function .
7.Relative Bioavailability of 2 Products of Loratadine Tablets in Human Body
China Pharmacy 2001;0(07):-
OBJECTIVE:To compare the relative bioavailability between2loratadine tablets(LORAX and LORAS)in human body.METHODS:22healthy male volunteers were enrolled to receive oral single dose(20mg)of either LORAX or LORAS tablets by crossover way,plasma concentrations of loratadine were determined by HPLC and pharmacokinetic param-eters were calculated by3p97program.RESULTS:The pharmacokinetic parameters of LORAX vs.LORAS were the fol-lowing,t 1/2Ke (3.03?0.98)h vs.(2.65?0.81)h;C max (8.59?6.70)vs.(9.59?8.22)ng/ml;t max (1.08?0.41)h vs.(1.21?0.28)h;AUC (0~t) (27.29?24.54)vs.(27.92?20.64)(ng?h)/ml.The relative bioavailability of LORAX was(100.63?14.27)%.CONCLUSION:2loratadine tablets were bioequivalent.
8.Recent progress in the investigation of cytokine and diabetes retinopathy
Chinese Ophthalmic Research 2009;27(12):1165-1168
Diabetic retinopathy is a progressive vision-threatening complication of diabetes mellitus.The characters of diabetic retinopathy in clude capillary occlusion,microcirculation disturbance and retina neovascularization near ischemic areas of the retina.The exact pathogenic mechanism is still unclear.Recent studies showed that it may be related to vascular inflammation of the retina.Cytokines can cause induction of proinflammatory and adhesion molecules and thereby increase monocyte-endothelial cell adhesion,which is now accepted as the early key event in the development of diabetic retinopathy.The functions of many cytokines such as vascular endothelial growth factor,transforming growth factor-β,basic fibroblast growth factor and ideas for medicine therapeutic to diabetic retinopathy are summarized in this review.
10. The peptide containing the conserved sequence of HPV L1 was used in the detection of polyvalent HPV-positive clinical specimens
Tumor 2008;28(10):864-868
Objective: To confirm that the antiserum induced by short peptide in the region of AA 448-477 at HPV16 L1 C-terminal can respond with many types of HPV L1. Methods: This sutdy synthesized a short peptide containing the conserved sequence of HPV L1 and immunized animal with the synthetic peptide to obtain the polyclonal antiserum. The type of HPV in clinical specimens, such as cervical cancer and condyloma acuminatum tissues, was identified by PCR. ELISA, Western blotting, and inummohistochemistry were used to determine whether the anti-serum of the short peptide could react with different types of HPV-positive specimens. Results: ELISA assay showed that the reaction between antigen and antibody was positive in HPV6, 11, 16, and 18 and other HPV-positive clinical specimens. Western blotting revealed that there was a strip at 56 kDa in all types of HPV-positive clinical specimens, but there was no strip in HPV-negative clinical specimens. Immunohistochemistry analysis demonstrated that the histological reaction had varying features in different clinical specimens. The positive-reaction appeared only in the epithelium tissues, which was regional and had apparent borders. Conclusion: This study confirms that the common conserved sequence really has HPV L1 common epitope. Its anti-serum can respond with many types of HPV L1. These findings provide an important basis for further researching a broad-spectrum HPV L1 vaccine or publicizing broad-spectrum HPV detection kits.
