Objective To explore main influencing factors of quality of life in patients with essential hypertension.Methods 644 patients with essential hypertension were investigated in a cross-sectional study with the questionnaire including demographic information,behaviour,years of hypertension,treatment,Chinese version SF-36 short form of quality of life.Influencing factors was analyzed by variance analysis and stepwise multivariate linear regression.Results Multivariable analysis showed that age,history of mental distress within the last one year,family income,physical exercise,attitude,knowledge,ordinary blood pressure,and community comprehensive management significantly influenced quality of life of patients with hypertension,with their standardized coefficients being-0.204,-0.097,0.102,-0.174,-0.197,0.129,-0.178 and-0.227 respectively.Conclusions To improve hypertension patients' quality of life,it is should be strengthened to control their blood pressure effectively,to enhance their health education and feasible exercise,and to improve their pessimistic attitude with psychological intervention.

Objective To analysis the relationship between the single nucleotide polymorphisms (SNPs) of G196A, C270T, G11757C, G712A and haplotypes frequencies of brain-derived neurotrophic factor (BDNF) gene and Chinese Han population with sporadic Alzheimer's disease (sAD). Methods The genotype and allele frequencies of BDNF G196A, C270T, G11757C and G712A were analyzed by polymerase chain reaction-restriction fragment length polymorphism technology in 106 sAD patients and 110 healthy controls. The software SHEsis was used to analyze the linkage disequilibrium and the haplotypes between the two groups. Results There were statistically differences in T allele frequeny of C270T (sAD vs control: 0.9% vs 4.5%) and A allele freguency of G712A (sAD vs control: 0.5% vs 4.5%) and in GG genotype frequeny of G712A (sAD vs control: 95.4% vs 91.8%) (all P

AIM: To clarify the effect of the specific sodium-hydrogen antiporter HOE642 on ischemia/reperfusion(I/R) injury including apoptosis, and the relationship between its effect and the time of HOE642 administration. METHODS: The isolated rat heart model were randomly divided into group A and B. Furthermore, the rat hearts in group A were divided into four subgroups including I/R, HOE-Pr+I/R, HOE-Is+I/R and HOE-Re, also the rat hearts in group B were divided into the following subgroups including control, I/R and HOE642+I/R. The LVDP, LVEDP, arrythmia coronary flow and the enzymatic activity in myocardium were measured in group A, and TUNEL method was applied to probe apoptosis in group B. RESLUTS: It was found that the LVEDP, arrythmias and the enzymatic activity including CK-MB and LDH were significantly lower in group HOE-Pr+I/R than that in group I/R, while the LVDP was obviously higher in HOE-Pr+I/R than that in I/R. The administration of HOE642 during ischemia could decrease LVEDP, arrythmias and enzymatic activity in myocardium, but not the LVDP. Furthermore, the results showed that HOE642 could inhibit apoptosis induced by ischemic/reperfusion injury. CONCLUSIONS: HOE642 is an effective cardio-protector in case of ischemic/reperfusion injury especially when it is applied before ischemia. The inhibition of apoptosis might be involved in the mechanisms underlying the protective effect of HOE642.

Objective To explore the risk factors for intracranial hemorrhage caused by late vitamin K deficiency bleeding(VKDB),in order to prevent and reduce the incidence of intracranial hemorrhage caused by late VKDB.Methods A retrospective analysis of the risk factors of late VKDB and intracranial hemorrhage was applied to 2 groups of patients in PICU and department of neurology of Beijing children's Hospital from Jan.2002 to Dec.2007.In group Ⅰ,there were 90 patients suffering from intracranial hemorrhage caused by late VKDB;while in group Ⅱ,there were 23 patients of late VKDB without intracranial hemorrhage.Within 12 hours of hospitalization,the following 9 items were checked:the cranial CT,blood calcium concentration,liver function,serum sodium,blood glucose,prothrombin time,partial thromboplastin time,fibrinogen concentration,and platelet.Ten possible relevant risk factors of gender,age,birth situation,feeding patterns,recent diarrhea,cytomegalovirus(CMV)infection,hypocalcemia,dysglycemia,hyponatremia,and abnormal liver function were analyzed by the method of non-conditional Logistic regression analysis.Results Statistically significant difference had been found in the 3 factors of hypocalcaemia,recent diarrhea,abnormal liver function(Pa

The use of flaps for plastic and reconstructive surgery is very popular today.More and more surgeons have realized that the blood supply plays an important role in the design and survival of flaps.After Ian McGregor and Ian Jackson first introduced the axial flaps into clinics,Mathes divided the flaps into two types in 1981,the fasciocutaneous perforator flaps and musculocutaneous perforator flaps.In 1989,the concept of perforator flap was first brought into clinical practice.With the development of microsurgery and anatomy,the epidermis of human skin is divided into areas based on the vascular anatomy.A new century of musculocutaneous perforator flaps has been established.The terminology,classification,characteristics and application of musculocutaneous perforator flaps are described in this paper.

Objective To evaluate and eliminate the potential bias between data obtained from dry and liquid biochemical assays,making data obtained by different assays matchable.Methods Bias estimation was performed based on document EP9-A2.Simple data comparison and methodology validation were performed after the experiment methods were modified with the estimated correction factors and interception.All the collected data were analyzed by EXCEL2007 software.Results The predicted bias of 4 of the 10 compared items exceeded their corresponding acceptable bias.After being adjusted by the coefficient and interception obtained from linear regression analysis,the four bias was improved and was within the acceptable range.The results of simple data comparison further confirmed this comparability.Conclusion Based on EP9-A2,we have established a protocol to obtain a consistency of data from different biochemical analyzers,which makes it possible that the detection results of the same patient from different detection systems can be used directly.The protocol has been approved by the experts during the medicinal laboratory accreditation of ISO15189.

Objective;To explore the relationship among parents' negative punishment,children's self-concept,and children's social behaviors.Methods;Data were collected from questionnaires given to a sample of 612 children from primary and secondary schools and their parents.Results;The structural equation modeling results showed parents' negative punishments could influence children's social behaviors directly and indirectly.In the indirect approach,through the mediating role of children's self-concept,parents' negative punishments could make a negative role on children's pro-social and aggressive behaviors,and a positive role on children's withdrawn behavior.In the direct approach,parents' negative punishments could make a positive effect on children's pro-social,aggressive and withdrawn behavior directly.Conclusion;Children's self-concept plays a mediating role between the relationship of parents' negative punishments and children's social behaviors.

Objective To observe the effects of Tanshinone Ⅱ A sodium sulfonate (TSS ) on ischemia/reperfusion (I /R) induced cardiac injury in male (Sprague-Dawley,SD ) and explore its mechanisms.Methods Rats were subjected to a 30 min coronary arterial occlusion followed by 24 hours reperfusion.The survival rats were randomly (random number)divided into sham group (Sham group,n =10),ischemia reperfusion group (I /R group,n =10),low dose of TSS group (TSS-L group,n =10), medium dose of TSS group (TSS-Mgroup,n =9),high dose of TSS group (TSS-H group,n =9).A MAP heart function analysis system was used to measure hemodynamic variables,and TTC staining method was used to detect the myocardial infarct size.The levels of Bcl-2,Bax,Caspase-3,Lc3B/Lc3A,Beclin-1 and high mobility group box1 (HMGB1)were detected by western blot method.All data were analyzed by using One-way analysis of variance (ANOVA)(LSD-t test).Results Cardiac function in I /R group was lower than that in Sham group,and that was significantly improved by pretreated with TSS (P <0.05),but there were no significant differences in Pmin and DAP between Sham group and I /R group (P >0.05 ).The percentage of myocardial infarct size in TSS pretreatment group was significantly smaller than that in I /R group (P <0.05 ).Compared with Sham group,levels of Caspase-3 and Bax increased,and the Bcl-2 content was reduced obviously in I /R group (P <0.05).TSS pretreatment significantly down-regulated the levels of Caspase-3 and Bax protein (P <0.01).At the same time,the level of Bcl-2 was increased in all TSS pretreatment groups (P <0.01).Compared with Sham group,the ratio of Bcl-2 /Bax in I /R group was lower (P <0.05),and that was elevated in TSS groups (P <0.05 ).The change of autophagy related protein beclin-1 and Lc3B/Lc3A was in similar trend,and the levels of beclin-1 and Lc3B/Lc3A in I /R group were lower than that in Sham group (P <0.05),and those were raised in TSS pretreatment groups (P<0.05).The level of HMGB1 in I /R group was higher than that in Sham group (P <0.05),and compared with I /R group,the level of HMGB1 significantly decreased in TSS pretreatment groups (P <0.01 ). Conclusions The tanshinone ⅡA sodium sulfonate can protect the myocardium from ischemia/reperfusion injury and the mechanism may be attributed to the inhibition of cell apoptosis and activation of cell autophagy.
