High mobility group box l protein (HMGB1) is a highly conserved non-histone DNA binding protein,which is widely distributed in eukaryotic cells.HMGB1 is an important proinflammatory cytokine,involving in various pathological and physiological processes,such as inflammation,neurogenesis and angiogenesis.In the early stage of intracerebral hemorrhage,HMGB1 can induce secondary brain injury,such as inflammatory reaction,neuronal necrosis,and brain edema.However,in the late stage of intracerebral hemorrhage,HMGB1 can promote angiogenesis and neurogenesis,and thus improving neurological function.HMGB1 will become a novel therapeutic target for intracerebral hemorrhage in the future.

Objective To summarize clinical results of 29 cases of multi-vessel coronary disease treated by hybrid revascularization.Methods A total of 29 consecutive patients(all male,aged 62.8?9.7 years) with coronary artery disease(two-vessel,n=10;three-vessel,n=19) were treated with minimally invasive direct coronary artery bypass(MIDCAB)(left internal mammary artery to left anterior descending artery,LIMA-to-LAD) and percutaneous coronary intervention(PCI) between January 2000 and April 2005.The left ventricular ejection fraction(LVEF) was 0.576?0.108.Concomitant diseases included hypertension in 23 patients,insulin-dependent diabetes mellitus in 5 patients,chronic obstructive pulmonary disease in 2 patients,and old myocardial infarction in 14 patients.Results The 29 patients received 33 grafts(LIMA: 27 grafts;great saphenous vein: 6 grafts).Balloon angioplasty was carried out in 41 coronary lesions,usually following surgery.The mean number of revascularization was 2.5 per patient.There was no surgery-related complications and mortality.The blood flow in the LIMA was 45?14 ml/min.The chest drainage volume was 274?197 ml.Blood transfusion was required in 2 patients(6.9%).The length of ICU stay was 1.9?0.1 d and the length of hospital stay was 4~11 d(mean,7.5 d).Follow-up for 2.2?0.9 years showed no late death and myocardial infarction.Postoperative New York Heart Association(NYHA) Classification showed Class Ⅰ in 25 patients and Class Ⅱ in 4 patients.Repeated angiography was conducted in 4 patients,which found great saphenous vein graft occluded in 1 patient and stent re-stenosis in 2 patients.Conclusions The midterm results of hybrid techniques for coronary artery disease are satisfactory.Hybrid procedure is beneficial to high-risk patients.The long-term results need further investigation.

Objective To Construct fusion gene DNA vaccine pcDNA3/STxB-VP1 and fusion gene DNA vaccine pcDNA3/MDC-VP1,then the two vaccines were inoculated to mice and stuy their immunological effects.Methods B subunit of Shiga Toxin(STxB)gene fragment were amplified by PCR from the DNA of Shigella dysenteriae and Macrophage-derived chemokine(MDC)gene fragment was amplified by RT-PCR from the total RNA of a mouse spleen cells.The DNA fragments of STxB and MDC waere respectively linked to coxsackievirus B3(CVB3)VP1 by a DNA sequence which encode a flexible polypeptide(15 amino acids)to construct eukaryotic expression plasmids pcDNA3/STxB-VP1 and pcDNA3/MDC-VP1.BALB/c mice were randomized to 6 groups which were respectively immunized pcDNA3,pcDNA3/STxB,pcDNA3/MDC,pcDNA3/VP1,pcDNA3/STxB-VP1 and pcDNA3/MDC-VP1 for 3 times at 3-week intervals,intramuscularly(i.m.)in tibialis anterior muscle.The levels of the serum neutralizing antibodies were detected 20d after each inoculation.The mice were challenged with 7 LD50 CVB3 3 weeks after the last immunization.Results The fusion gene vaccines pcDNA3/STxB-VP1 and pcDNA3/MDC-VP1 were constructed successfully.The survival rates of each group were 10%,10%,15%,40%,20% and 75%,respectively,and the levels of neutralizing antibody titers,virused titers,were all consistent with those survive rates in each group.Conclusion Comparing with pcDNA3/VP1,pcDNA3/MDC-VP1 vaccine can induce a high level of neutralizing antibody titers and result in a higher survival rate in mice,while pcDNA3/STxB-VP1 induce a low level of neutralizing antibody titers and result in a lower survival rate in mice.

ObjectiveTo summarize the short-term effects o f Symmetry aortic co nnector in off-pump coronary artery bypass grafting (OPCAB) operation. MethodsTwo hundreds and four patients suffering from coronary artery d isease underwent OPCAB from September 2002 to June 2003. Among the 204 patients, saphenous vein grafts were used in 167 patients and Symmetry aortic connectors were adopted in 100 of them.ResultsOf 142 connectors used, 2 connectors fai led and manual r epairs were required in 3 cases because of anastomotic leakage, the success rate being 96 5% (137 of 142). The number of proximal anastomosis was (1 4?0 5) per case and the number of distal anastomosis (3 5?0 8) per case. The proximal a na stomotic blood flow was (46 5?22 3) ml/min. The fitting time for connectors w as (4 0?1 1) min, and anastomoses were all accomplished within 10 seconds. The op eration time was (3 2?0 4) hours. The operative death rate was 1% (1 of 100). R e-operation of thoracotomy was required in 1 case because of bleeding but not an astomotic bleeding. No myocardial infarction or stroke occurred in the peri-oper ative period. The postoperative drainage amount was (547?247) ml. The blood tra nsfusion rate was 36 0% (36 of 100). The postoperative hospital stay was (7 8 ?1 6) days.ConclusionsSymmetry aortic connector can be saf ely and effectively used in coronary artery bypass grafting operations, with satisfactory short-term clinical effects. The procedure may shorten operation time, avoid aortic clampi ng, and lower the incidence of stroke.

Objective To summarize the mid-term outcomes of minimally invasive direct coronary artery bypass (MIDCAB). Methods A series of 33 patients underwent MIDCAB from November 2000 to April 2003: 29 of them received MIDCAB only and 4 received the hybrid approach operation (combining MIDCAB of the left anterior descending artery with percutaneous coronary intervention of the remaining diseased coronary arteries). Out of the 33 cases, conventional MIDCAB was carried out in 25 cases, 4 underwent thoracoscopy-assisted operation and 4 received the surgery with the assistance of the AESOP robot system. Results No operation-related deaths or complications were seen in the study. The extubation time was (7.5?1.9) hours, the chest drainage volume was (274?197) ml, the blood transfusion rate 9.1% (3/33) and the postoperative hospital stay (6.9?1.7) days. Follow-up in all the 33 cases for (24.3?5.7) months revealed no long-term deaths and the recurrence rate of angina was 9.1% (3/33). Postoperative coronary angiography in 4 cases found 1 case of 50% stricture of anastomosis and 3 cases of anastomotic patency between the anterior descending artery and left internal mammary artery. Postoperative catheter revascularization was required in 2 cases (6%). Conclusions The mid-term outcomes of MIDCAB is satisfactory.

Thyroid diseases are often accompanied with dyslipidemia.In me past,low level of myroid hormone(TH) was considered a main factor in causing elevated level of blood cholesterol in hypothyroid patients.However,some clinical features can not be explained by this traditional theory. For example,in subclinical hypothyroid cases,both levels of thyroid-stimulating hormone (TSH) and serum total cholesterol (TC) increase,while TH level remains normal.From this phenomenon,we speculate that in case with hypothyroidism,not only there is a relationship between serum TC and TH levels,but also serum TC level change is related to TSH in some way,which has not been noticed.The purpose of this paper is to review the new and most advanced progress in the research of TSH and cholesterol.

Objective To investigate the thyroid hormone changes and their relationship with the state of severity in critically ill patients. Methods Ninety-two patients with no thyroidal illness syndrome admitted to the ICU from January ,2009 to December,2009 were enrolled in this study. The common situations and the score of acute physiology and chronic health evaluation Ⅱ were assessed on addmission. We measured the thyroid hormone levels on the day after admission and analysed whether thyroid hormone levels were related to disease severity. Results The thyroid hormone levels in septic shock group [TT3 (1.16 ± 0.24) nmol/L, TT4 (68.93 ± 24.11) nmol/L, FT3 (3.76 ± 0.21) prnol/L, FT4 (16.40 ± 2.74) pmol/L, TSH (1.58 ± 1.01) mU/L] were significantly lower than those in non-septic shock [TT3 (1.50 ± 0.25) nmol/L, TT4 (91.70 ± 21.90) nmol/L, FT3 (4.24 ± 0.45) pmol/L, FT4(17.98 ± 3.28) pmol/L, TSH (2.43 ± 2.76) mU/L] (P ＜ 0.05). The serum thyroid hormone levels of free triiodothyronine (FT3) ,free thyroxine (FT4) were related to the score of APACHE Ⅱ in septic shock(P ＜ 0.05).Conclusions The levels of thyroid hormone were significantly lower in critically ill patients than the control group and had positive correlation with the disease severity.
