Objective To systemically review the efficacy and safety of heparin for treatment of sepsis.Methods Database search of IM/MEDLINE,Cochrane Library,SCIE,CBM,CNKI,VIP Data,WanFang Data (from January 2000 to June 2012) was conducted.The quality of included randomized controlled trials (RCTs) about heparin for treatment of sepsis was assessed,and relevant data were extracted according to the inclusion and exclusion criteria.Then meta analysis was performed using RevMan 5.1.Results 17 trials with 1 167 participants were included.The results of meta-analysis showed:compared with the control group,heparin significantly decreased 28-day mortality in patients with sepsis [odds ratio (OR) =0.59,95％ confidence interval (95％CI) 0.45-0.77,P=0.0001] ; heparin did not deteriorate coagulation disorders,but corrected sepsis-induced platelet (PLT) count reduction [mean difference (MD) =13.94,95％ CI 10.15 to 17.72,P＜0.000 01],while it had no significant effect on the activated partial thromboplastin time (APTT) and prothrombin time (PT,APTT:MD=-3.18,95％CI-6.88 to 0.53,P=0.09; PT:MD=-0.68,95％ CI-1.48 to 0.12,P=0.09).There was no significant difference between the two groups in the incidence of bleeding either.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of heparin group was significantly lower than that of the control group (MD=-2.58,95％CI-3.29 to-1.87,P＜0.000 01),and the incidence of multiple organ dysfunction syndrome (MODS) was significantly lower than that of the control group (OR=0.32,95％CI 0.17 to 0.61,P=0.000 6).In addition,heparin could shorten intensive care unit (ICU) stay (MD=-4.43,95％CI-6.79 to-2.07,P=0.000 2),whereas it showed no significant effect on the total length of hospital stay.Conclusions Heparin can ameliorate sepsis,and has high degree of safety and lower hospital expense.Due to limitation of the quality of included studies,larger sample and well-designed RCTs are needed to further support this conclusion.

Aim To investigate the effect of sevoflurane pretreatment on the nuclear factor kappa B(NF-?B)-DNA binding activity of leukocyte in peripheral blood of the patients undergoing cardiac valve replacement under cardiopulmonary bypass(CPB).Methods Twenty patients undergoing cardiac valve replacement under CPB were divided randomly into two groups:control group(group C)and sevoflurane pretreatment group(group S).All patients were induced with midazolam 0.08~0.12 mg?kg-1,fentanyl 5~10 ?g?kg-1 and vecuronium 0.1 mg?kg-1.After endotracheal intubation,mechanical ventilation was conducted with 100% oxygen.Anesthesia in group C was maintained with intermittent intravenous fentanyl and midazolam,while in group S maintained with 2MAC sevoflurane besides fentanyl and midazolam intermittently before CPB.The anesthesia depth was kept to maintain the systolic pressure within 90~120 mmHg in both groups.Sevoflurane was discontinued at the initiation of CPB,and the following anesthetic regimen was the same as that in group C.To examine the NF-?B-DNA binding activity,the arterial blood samples were withdrawn at the following time point:after endotracheal intubation and before inhaling sevoflurane(T0),30 min(T1),1 h(T2),2 h(T3),6 h(T4)after aortic de-clamping.Electrophoretic mobility shift assay(EMSA)was used to measure the NF-?B-DNA binding activity of leukocyte.The dosage of fentanyl,midazolam,dopamine,sodium nitroprusside and the rate of spontaneous heart resuscitation in both groups were recorded.Results The NF-?B-DNA binding activity in group C was increased significantly after aortic de-clamping,and it reached to maximum at T1,but it was not changed significantly in group S from T0 to T4.The value of EMSA at all time points was lower in group S except T0 than that in group C(P

Aim To investigate the effects of Isofluraneon function,metabolism,ATPase activity and free radicals in isolated ischemia /reperfusion(I/R) rat hearts.Methods 56 SD rats were randomly divided into 7 small groups(n=7),or 2 big groups according to given drug.In a normal thermal isolated Langendorff rat heart model,Myocardial Adenosine triphosphate(ATP),Malodialdehyde(MDA),Activity of Ca2+-ATPase,Na+,K+-ATPase and Superoxide Dismutase(SOD)were determined.Results In isoflurane group,LVDP and dp/dt decreased,CF and ATP increased while the activity of Na+,K+-ATPase remained unchanged.The myocardial ATP content decreased slowly in isoflurane group.At the end of reperfusion,ventricular function,CF,myocardial ATP content and the activity of Ca2+-ATPase and SOD in isoflurane group were significantly higher while myocardial MDA was significantly lower than those in control group.Conclusion Isoflurane can depress myocardial systolic function and activity of Ca+-ATPase in normal myocardium,improve the recovery of function and metabolism,and increase CF and the activity of Ca2+-ATPase and Na+,K+-ATPase.

Purpose To explore the association between ultrasound contrast agent injection volume as well as regurgitation and tubal patency. Methods SonoVue contrast agent was used for 515 cases of infertility transvaginal four-dimensional ultrasound imaging hysterosalpingography, recorded the amount of contrast agent injection, regurgitation, and compared contrast agent injection volume and regurgitation in different patency. Results The ultrasound contrast agent injection volume between bilateral patency with bilateral passable and one side patency one side passable as well as one side patency one side barrier, between one side patency one side passable and one side patency one side barrier had no significant difference (U=1467.0-4843.0, P>0.05);and it had statistical difference between any other two conditions (U=273.5-6160.0, P<0.05). The regurgitation between bilateral passable and bilateral barrier, one side passable one side barrier, between bilateral barrier and one side patency one side barrier, one side passable one side barrier, between one side patency one side passable and one side patency one side barrier had no statistical difference (U=949.5-6378.5, P>0.05), and it had statistical difference between any other two conditions (U=919.5-5126.5, P<0.05). Conclusion Ultrasound contrast agent injection volume and regurgitation in hysterosalpingography are associated with tubal patency, which can be used as objective indexes for assessing tubal patency, and provide basis for tubal patency.

Objective To analyse the correlation of age and BMI with prostate-specific antigen (PSA)in male younger than 50 years of age. Methods The routine health examination data of 6808 males, younger than 50 years of age, were collected and reviewed. The height and weight were measured, so as to calculate the body mass index (BMI). Serum PSA was also examined. Eligible men were classified into age groups spanning 10 years. BMI was categorized as normal (BMI 18. 5 - 22. 9) , overweight (BMI 23. 0-24. 9), obese (BMI 25. 0 - 29. 9) , and very obese (BMI≥30. 0) according to the re-defined World Health Organization criterion for the Asia Pacific Region. PSA levels were stratified by age and BMI category. Results The mean age was (39. 2±7. 0)years, mean BMI (25. 6± 4. 7)kg/m~2 and mean PSA (0. 89±0. 56)ng/ml for the whole population. The PSA level in 10 - 19 age group was significantly lower than the other three groups (P<0. 01) and no significant difference was found among the other three groups. The BMI had negative correlated with PSA even when comparing in sub-age groups, except the 10-19 age group. Spearman analysis also found PSA had significant positive correlation with age and negative correlation with BMI. Conclusions Serum PSA level changes significantly with age in adolescence whereas quite slowly between 20-50 years of age. BMI has negative influence on PSA in male younger than 50 years of age.

The study was conducted to explore the response of growth and yield of Tulipa edulis to flower bud removal and artificial pollination. And flower bud removal and artificial pollination were carried out in the squaring period and bloom stage respectively. The morphological index and biomass indicators were determined and the yield was counted in harvest time. Result showed that flower bud removal was beneficial to the growth of T. edulis, resulting in increasing growth index, biomass as well as the yield of bulb. The diameter and dry weight of T. edulis fruit by artificial pollination were increased significantly compared with the control. Seed setting percentage increased to 100%, and the number of seed as well as the single grain weight increased by 69.03% and 16.48%, respectively, which did not significantly affect the bulb production. In conclusion, Flower bud removal treatment accelerates bulb biomass increase, so as to improve its yield. Artificial pollination raised significantly seed setting percentage, seed number as well as the single grain weight.

OBJECTIVETo analyze the relationship between the pulse pressure (PP) and atherosclerotic renal artery stenosis (ARAS) in middle-age and eldery paients with hyperensio, so as to provide the basis for the diagnosis and treatment of ARAS.

METHODSWe tetro spectively analyzed the data of 257 patients with hypertension undergoing renal arteriography at General Hospital of PLA between 2009 and 2014. Their mean age was (64.09 +/- 7.81) years. According the results of arteriography, they were divided into two groups: ARAS group (n = 145), and non-ARAS group (n = 112). Their PP and multinomial clinical indexes with ARAS were statistically analyzed.

RESULTSSingle factor correlation and Logisitic analysis showed that age, PP, serum creatinine (SCr) levels, and new onset of hypertension after 50 years of age were strongly positively related to ARAS. The age and PP and SCr was a team of continuous variable.

CONCLUSIONPP was the first new risk factor of ARAS in middile-aged and elderly patients with hypertension. It is suggested that PP may be a early predictive indicator and a new therapeutic target for ARAS.
