Objective:To explore clinical characteristics of reperfusion arrhythmia (RA) during direct percutaneous coronary intervention (PCI ) in patients with acute myocardial infarction (AMI ) and its influence on prognosis . Methods :Clinical data of 180 AMI patients undergoing direct PCI in our hospital from Jan 2013 to Dec 2014 were retrospectively analyzed .Results:RA rate in 112 patients was 62.22% and it's correlated with age (r=0.614 ,P=0.026) ,the age is more older ,the RA rate is more higher .Compared with multi -vessel coronary disease patients , there was significant rise in incidence rate of RA (48.33% vs .69.17% , P=0.021) in single -vessel disease pa‐tients ;compared with left anterior descending group and left circumflex group ,there was significant rise in inci‐dence rate of RA (61.67% vs .53.33% vs .71.67% ) in right coronary artery group ,and there was significant difference between any two groups , P<0.05 all .Compared with patients with coronary recanalization within 6~12h ,there was significant reduction in incidence rate of RA (66.67% vs .47.62% ,P=0.025) in those within 6h . There were no significant difference in incidence rates of death ,reinfarction and stroke during hospitalization and six months after PCI between RA group and no RA group ,P>0.05 all .Conclusion:The occurrence of reperfusion arrhythmia in patients with acute myocardial infarction during direct percutaneous coronary intervention is associat‐ed with number of diseased vessels ,infarct vascular type and coronary recanalization time .

Clonal hematopoiesis is a special mode of hematopoiesis in which hematopoietic stem cells with specific genetic and molecular biological characteristics differentiate into mature blood cells. It is the basis of a variety of hematological diseases. In depth study of its etiology, mechanism and characteristics are conducive to our understanding of the value of clonal hematopoiesis in different populations or diseases. This article reviews the latest progress in clonal hematopoiesis and its related clonal diseases.

ObjectiveTo observe the defervesce effect of bloodletting plus puncturing and cupping treatment in treating common cold due to wind-heat.MethodSixty-two patients with fever due to external contraction were randomized into a treatment group of 30 cases and a control group of 32 cases. The control group was intervened by muscular injection of Antodin plus oral administration ofQing Kai Linggranules 3 g, three times a day; the treatment group was by cupping and bloodletting at Dazhui (GV14) and Feishu (BL13), bloodletting at Shaoshang (LU11) and Shangyang (LI1), and cupping at back in addition to the intervention given to the control group. The clinical efficacy, treatment acting time (body temperature decreased by 0.5℃) and defervesce time were observed. ResultIn the treatment group, the acting time and defervesce time were respectively (6.11±2.18)h and (27.11±10.84)h, and total effective rate was 93.4%; in the control group, the acting time and defervesce time were respectively(14.31±5.43)h and (39.14±13.45)h, and total effective rate was 84.4%, and the differences were statistically significant (P<0.05).Conclusion Acupoint bloodletting plus bloodletting-cupping method can produce a significant defervesce effect in treating common cold due to wind-heat.

AIM: To dissociate and determine the chemical components of volatile oil from Salsola col-lina Pall.in Shandong Province METHODS: The chemical components of volatile oil were analyzed by gaschromatography-massspectraphy(GC/MS). RESULTS: Fifty-nine constituents were identified,which accounted for 87.63% of volatile oil,the major chemical componets in the volatile oil were terpenes and terpene ramifications. CONCLUSION: This method is reliable,stable and repeatable.the data can provide resources for expolitation of Salsola col-lina Pall.

Objective:To investigate the effect of estrogen on the expression and distribution of IL-1 in the remodeling osteoporotic alveolar bone.Methods:Ovariectomy was performed on 30 female SD rats and sham operation on 15(control group).When osteoporosis was developed in the 30 ovary-removed rats,the left maxillary molars of all the rats were extracted.On the following day 15 of them were treated with intramuscular estrogen injection at 20 ?g/kg once every 3 days(treatment group).Another 15 rats with ovary removed received no treatment(osteoporosis group).7,30 and 60 days after teeth extraction 5 rats were killed respectively in each group.IL-1 expression in alveolar bone was examined immunohistochemically,and semiquantitative analysis of cellular-staining intensity was done by microphotometry.Results:The positive IL-1 expression were mainly located in the osteoclasts,vascular endothelial cells and fibroblasts.7 days after teeth extraction the cellular-staining intensity of IL-1 in control group,osteoporosis group and treatment group was 0.11?0.019,0.36?0.038 and 0.18?0.025 respectively(control or treatment group vs osteoporosis group,P

Objective To analyze the causes for the biological monitoring abnormal results of the pressure steam sterilizer to eliminate non-standard operation and hidden risks during biological monitoring.Methods Totally 34 secondary or above medical institutions in Chongqing were selected randomly,and questionnaire survey was carried out over biological monitoring abnormal results and main influencing factors of the pressure steam sterilizer.Results Of the 126 abnormal results,there were 63 positive results (accounting for 50％) and the main influencing factors included expiration,aged seal ring,low-efficiency vacuum pump,nonstandard loading,bioindicator reproduction before sterilization,false positive result,polluted moist incubator and etc;There were 35 cases of results related to fast reader (accounting for 27.78％) and the main factors consisted of failure of reading light,improper input of bioindicator,dusts in the reading hole and etc;There were 18 cases of bioindicator discoloration before culture (accounting for 14.28％) and the main factor was reproduction occurred before the gemma was inactivated;There were l0 cases of nondiscoloring in case of positive control (accounting for 7.94％) and the main factors included non-crushed indicating mediostratum cultured in the incubator,insufficient shaking after crushing mediostratum and etc.Conclusion The main factors for abnormal biological monitoring of the sterilizer involve in equipment,personnel and material,and the quality control has to be executed from the three aspects.

OBJECTIVE:To explore the effects of Haikangling Mixture on immunological function in immunosuppressed mice induced by cyclophosphamide. METHODS: Mice were given Haikangling Mixture intragastrically for 14d, and the level of hemolysin was determined by sheep erythrocyte (SRBC) immunization to exploer the influence of Haikangling on humoral immunity in mice; splenic lymphocytes were measured by MTT to observe the influence on cell immunity; the clearance of macrophage were measured by carbon particle clearance method to explore the influence on non-specificity immunity. RESULTS: The level of hemolysin, the cell reproductive activity, splenic lymphocytes and the phagotrophy of mononuclear macrophage were improved obviously by Haikangling Mixture in immunosuppressed mice induced by cyclophosphamide. CONCLUSION: Haikangling Mixture can enhance the immunological function in immunosuppressed mice induced by cyclophosphamide.

Objective Retrospective observating the diminishing inflammation and lowering enzymatic effect with diammonium glycyrrhizinate (ganlixin injectionfluid) on hepatitis, such as chronic hepatitis, hepatocirrhosis, drug induced hepatitis and alcoholic hepatitis. Methods The 629 case hepatitis sufferers, including chronic hepatitis with light to middle degree, hepatocirrhosis, drug induced hepatitis and alcoholic hepatitis, were treated with 150 mg diammonium glycyrrhizinate added into 250 ml 5 % to 10 % glucose injection liquid. Another 127 chronic hepatitis sufferers treated with injecho potenl ini were seen as contrast. When the treatment was over, the level of alanine aminotransferase (ALT) and serum bilirubin (SB) and symptom of patients in two groups were analysed. Results The level of ALT and SB dropped more rapidly than that in contrast group, but there were no marked difference in symptoms recover. After 17 days therapy, there are 93.3 % patients with ALT normal level in treating group, but 73.3% in contrast group (P
