Objective To investigate clinical efficacy and safety of half quantity of tirofiban on elderly patients with ST segment elevation myocardial infarction ( STEMI ) .Methods 120 elderly patients with STEMI underwent emergency PCI patients,120 cases of digital method were randomly divided into the control group and observation group,60 cases in the control group with conventional surgery and drug treatment,the observation group of 60 cases on the basis of conventional therapy was given to half the amount for tirofiban,the two groups were observed in the risk of bleeding, the occurrence of adverse cardiovascular events after operation.Results The postoperative bleeding risk of the observation group compared with the control group had no significant difference(χ2 =1.51,1.35, 0.94,P=0.643,0.768,0.578);for the observation group in 30 days after operation,90 days of re infarction,death and target vessel revascularization rate compared with the control group decreased,the difference was statisticallysig-nificant(30 days after operation,χ2 =9.54,18.33,16.75,P=0.043,0.029,0.031;90 days after operation,χ2 =17.48,21.78,19.54,P=0.034,0.011,0.021).Conclusion Semi quantity for tirofiban can reduce the risk of elderly patients with STEMI after PCI,improve clinical outcome,which will not increase the risk of hemorrhage.

Ascites is an important indicator of poor prognosis of liver cirrhosis.Although several guidelines and consensus statements on the management of ascites have been published in the past years,there are still a lot of controversial problems in this regard.The current contro-versial problems and difficulties in the management of ascites,such as the timing of sodium supplementation or sodium restriction,the selec-tion of diuretics,the application value of aquaretics,the strategy of albumin administration after large-volume paracentesis,and the indica-tions and efficacy of transjugular intrahepatic portosystemic shunt,are reviewed.It is pointed out that further studies on these problems with evidence-based medicine means will enhance the diagnosis and treatment of cirrhotic ascites and improve patients'prognosis.

The established immunodeficient animal models could be used as valuable resource for mechanism re-search of related disease in humans, drug discovery and development, translational research and stem cell research.How-ever, it is difficult and low-efficient to establish the genetic modified animal models using traditional technologies.The re-ports for immunodeficient animal models are few in middle-size and large animals.Recently, several effective gene-targeting tools, including ZFNs, TALENs, CRISPR/Cas9, develop quickly and provide technology basis for the establishment of im-munodeficient animal models.In this paper, the technology principles and research progresses of ZFNs, TALENs, CRISPR/Cas9 are introduced.The significant progresses of these emerging technologies achieved in immunodeficient ani-mal models are also elaborated, including KO Rag1/Rag2 rabbit, KO Rag1/Rag2 pig, KO IL2rg pig, KO Ppar-g/Rag1 monkey, and so on.In addition to being models for researching SCID-related diseases in humans, and evaluating the effica-cy and safety of stem-cell engraftment, these models may be also useful to develop surgical procedures for placement of grafts before clinical trials in humans, to produce humanized animals and bridge the gap between laboratory animal and medicical research.The immunodeficient animal models described here represent a step toward the comprehensive evalua-tion of preclinical cellular regenerative strategies.

OBJECTIVE:To compare the efficacy and safety of levonorgestrel intrauterine system and mifepristone in the treat-ment of perimenopausal dysfunctional uterine bleeding. METHODS:200 patients with perimenopausal dysfunctional uterine bleed-ing were randomly divided into observation group (100 cases) and control group (100 cases). Patients in the observation group placed levonorgestrel intrauterine system (containing levonorgestrel 52 mg),patients in control group received Mifepristone cap-sule 10 mg/d,oral,the treatment course for 2 groups were 3 months. Clinical efficacy,endometrial thickness,menstruation(PBAC score),hemoglobin level before and after treatment and incidence of adverse reaction in 2 groups were observed. RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,incidence of adverse reactions was significantly lower than control group,the differences were statistically significant(P<0.01). Before treatment,there were no significant differences in the endometrial thickness,PBAC score and hemoglobin level between 2 groups;after treatment,endome-trial thickness and PBAC score were significantly lower than before,and observation group was lower than control group;hemoglo-bin level was significantly higher than before,and observation group was higher than control group,the differences were statistical-ly significant(P<0.01 or P<0.05). CONCLUSIONS:The efficacy and safety of levonorgestrel intrauterine system are significant-ly superior to mifepristone in the treatment of perimenopausal dysfunctional uterine bleeding.

Objective To observe and analyze the four changes of plasma D- dimer and coagulation in pregnant women at different stages of pregnancy, and to explore the value of the test. Methods The subjects of this study were 120 pregnant women who underwent routine physical examination in our hospital, according to different stages of pregnancy (early pregnancy, middle pregnancy, late pregnancy, and before delivery) Four D- dimer and four blood coagulation tests were performed in pregnant women, and the results were observed and compared. Results During the pregnancy, D- dimer has increase trend (P<0.05); early in pregnancy, pregnancy and late pregnancy, PT has shortened(P<0.05); pregnancy, APTT has shortened (P<0.05), at the end of pregnancy and parturient period, showing a significant shortening (P<0.05); phenomenon in early pregnancy to mid pregnancy stage, FIB increased significantly (P<0.05), and at the end of pregnancy to perinatal period, with a sharp increase (P<0.05). Conclusion It is of great significance to perform dynamic monitoring of of plasma D- dimer and coagulation four indices in pregnant women during pregnancy.

BACKGROUND:Stem cel s have the potential to differentiate into various organs and tissues. In recent years, stem cel s have been proved to differentiate into hair fol icles under certain conditions. OBJECTIVE:To review the research progress and prospect of stem cel s differentiating to hair fol icles, thereby providing a reliable basis for clinical treatment of serious hair fol icle injury. METHODS:A computer-based search of PubMed, EMBASE, WanFang, CNKI databases was performed for related articles published between 2013 and 2015, using the keywords of“cel hair, fol icle stem, medicine regenerative, differentiation”in English and Chinese. A total of 207 articles were retrieved, and final y 34 articles were included in result analysis. RESULTS AND CONCLUSION:Stem cel s from different sources al have the ability to differentiate into hair fol icles under certain inductions. However, it is important to seek more scientific and rational methods for the differentiation of stem cel s into hair fol icles based on overcoming their own shortcomings. A great progress has been made in animal experiments and subclinical trials, and even a great breakthrough in some aspects. Further studies on combining the advantages and overcoming the shortcomings of various stem cel s during differentiation are required for the clinical treatment of serious hair fol icle injury.
