Objective Through studying change of serum level of IL-10 in patients of severe trauma with haemorrhagic shock,to investigate effect of severe trauma with haemorrhagic shock bypass on anti-infiammatory reaction in patients.Methods Menbers of experimental group are 43 patients of Severe trauma(ISS scope≥16).43 patients scheduled for attending with haemorrhagic shock are divided into simple severe trauma group(group B)and severe trauma with haemorrhagic shock(group C);and healthy control group(group A)is made up of randomly seleeted 20 healthy people of medical examination.Blood samples for cytokines and organ function were collected from the vetn of menbers of experimental group(B and C)with limosis at the following time:that day of injury,(T1),3th (T2),5th(T3),and 14th(T4)day after injury;blood samples of healthy control group(A)with limosis were collected at that day of examination;serum level of IL-10 was measured by radioimmunoassay.Results In experimental group(B and C),the serum peak level of IL-10 emerged on T3 and then stepped down;the serum peak level of them increased abviously compared with group A(P<0.05 or P<0.01).Furthermore,the serum level of them in C group was usually higher than that on the same time in group B.Conclusion It was longer and severer in time and degree that effects of severe trauma with haemorrhagic shock bypass on IL-10 of body compared with that of simple severe trauma.

Objective To observe the effect of long-term intensive glucose control therapy on diabetic retinopathy in outpatients with type 2 diabetes mellitus.Methods Forty-nine patients with type 2 diabetes mellitus were randomly assigned to participate in the trial from 2002 to 2007,receiving either intensive (24 cases) or standard glucose control (25 cases).The patients were examined by the same ophthalmologists to identify any new diabetic retinopathy (DR).After 5 years of intensive glucose control,all of the patients were asked to attend our clinic every 6 months,but no attempts were made to maintain their previously assigned therapies.Hemoglobin A1c (HbA1 c) was measured regularly.In November of 2009,a retinal examination was carried out by the same ophthalmologist who worked in the trial.The visual acuity,lens,vitreous body and fundus were examined after pupil dilation to identify diabetic retinopathy (DR).Fundus fluorescein angiography and retinal laser photocoagulation were carried out when necessary.Results In the second year after enrollment in the trail,the median HbA1c level of the intensive-therapy group was significantly lower than that of the standard-therapy group [(6.3 ± 0.6) % vs.(7.2 ± 1.2) %,t =2.09,P < 0.05],and was maintained in a controlled level throughout the following 4 years.During the post-trial monitoring,no new case of of macula edema or diabetic associated blindness occurred in either intensive or standard-therapy group,the whole occurrence of micro-aneurysms,fundus hemorrhage,as well as those who needed retinal laser photocoagnlation and lowering in visual acuity in intensive-therapy group was lower than that in the standard-therapy group (3 vs.14,1 vs.7,2 vs.4,3 vs.11,respectively ;9 vs.36,totally,x2 =4.719,P < 0.05).During the first post-trial monitoring,there was no difference in median HbAlc level between intensive-therapy group and standard-therapy group [(7.2 ± 1.1) % vs.(7.3 ± 1.3) %,t =0.25,P =0.806],which was sustained in the following years.In the trail,no new case of fundus hemorrhage or diabetic associated blindness occurred in intensive-therapy group during the five-year period of therapy.Number of new episodes of micro-aneurysm,macula edema were less in intensive-therapy group than that in standard-therapy group,number of new episodes of lowering in visual acuity,and those who needed retinal laser photocoagnlation,were significantly less in intensive-therapy group than that in standardtherapy group(15 vs.25,4 vs.23,Z =-4.459,P < 0.05) during five-year follow-up.Conclusions The benefit of reduced incidence of diabetic retinopathy in intensive glucose can be maintained because of the legacy effect.

Objective To evaluate the impact of different doses of recombinant human B-type natriuretic peptid (rh-BNP) within the dosage of clinical rage on oxygen consumption during acute myocardial infarction (AMI) with heart failure (HF). Methods AMI-HF model of York pig was established by occluding coronary artery with balloon combined with in-jecting microthrombus. Then animals were randomized into rhBNP group and control group. Clinical dose of rhBNP ( 1.5μg/kg bolus followed by a continuous infusion with speed of 0.01, 0.02 and 0.03μg · kg-1 · min-1 for 60 minutes respectively in turn) was administrated in rhBNP group while equal volume of saline was given in the control group. Myocardial oxygen up-take (MOU) was measured by drawing blood from coronary artery and coronary sinus using a catheter. Coronary diameter was determined using quantitative coronary angiography. The observation points were at baseline (T0), instant after the mod-el establishment (T1), 60 min after continuous rhBNP infusion of 0.01, 0.02, 0.03μg·kg-1·min-1 (T2-T4) respectively. Re-sults Compared with the control group, pulmonary capillary wedge pressure, central venous pressure, heart rate, systolic blood pressure and MOU were significantly decreased after rhBNP administration. And cardiac output and coronary diame-ter were obviously increased with addition of rhBNP. There is a interaction of drug intervention and time. In rhBNP group, MOU was significantly decreased with drug administraion (T2-T4 vs T1,mL O2/L: 10.61 ± 0.35,9.85 ± 0.60,9.79 ± 0.31 vs 11.59 ± 0.37). Conclusion Intravenous administration of rhBNP in AMI-HF model could decrease MOU and PCWP while increase the cardiac output.

Vertebrobasilar dolichoectasia(VBD ) can increase the risk of stroke. Significant expansion, elongation and tortuosity of the vertebrobasilar arteries are the main morphology manifestations of VBD. However, there is no consensus on the quantitative imaging assessment of VBD. Many studies showed that some quantitative parameters, such as basilar artery length and bending length, basilar angulation, vertebral tortuosity index can be used for the quantitative imaging assessment of VBD.

OBJECTIVE To investigate the mechanism of Yifei xuanfei jiangzhuo formula (YFXF) against vascular dementia (VD). METHODS The differentially expressed genes of YFXF (YDEGs) were obtained by network pharmacology. High-risk genes were screened from YDEGs by using the nomogram model. The optimal machine learning models in generalized linear, support vector machine, extreme gradient boosting and random forest models were screened based on high-risk genes. VD model rats were established by bilateral common carotid artery occlusion, and were randomly divided into model group and YFXF group (12.18 g/kg, by the total amount of crude drugs), and sham operation group was established additionally, with 6 rats in each group. The effects of YFXF on behavior (using escape latency and times of crossing platform as indexes), histopathologic changes of cerebral cortex, and the expression of proteins related to the secreted phosphoprotein 1 (SPP1)/phosphoinositide 3-kinase (PI3K)/protein kinase B (aka Akt) signaling pathway and the mRNA expression of SPP1 in cerebral cortex of VD rats were evaluated. RESULTS A total of 6 YDEGs were obtained, among which SPP1, CCL2, HMOX1 and HSPB1 may be high-risk genes of VD. The generalized linear model based on high-risk genes had the highest prediction accuracy (area under the curve of 0.954). Compared with the model group, YFXF could significantly shorten the escape latency of VD rats, significantly increase the times of crossing platform (P<0.05); improve the pathological damage of cerebral cortex, such as neuronal shrinkage and neuronal necrosis; significantly reduce the expressions of SPP1 protein and mRNA (P<0.05), while significantly increase the phosphorylation levels of PI3K and Akt (P<0.05). CONCLUSIONS VD high-risk genes SPP1, CCL2, HMOX1 and HSPB1 may be the important targets of YFXF. YFXF may play an anti-VD role by down-regulating the protein and mRNA expressions of SPP1 and activating PI3K/Akt signaling pathway.
