Objective To investigate prevalence and risk factors of peripheral artery disease (PAD), metabolic syndrome (MS) and peripheral artery disease complicated with metabolic syndrome among Kazakh adults lived in Xinjiang Yili prefecture. Methods Four-stage cluster sampling method was used to select adults aged 35 years and over for the study from six cities and prefectures of Xinjiang. All the participants were interviewed with questionnaire to collect their demographic characteristics. Physical checksup and blood biochemical measurements were performed for all of them, as well as blood pressure was measured in their lower legs and arms to calculate ankle brachial pressure index ( ABPI), a ratio of the blood pressure in the lower legs to that in the arms. Only data of Kazakh adults in Yili prefecture were analyzed in this paper, including prevalence and risk factors for PAD and MS, as well as their relationship.The patients with PAD were divided into two groups, one complicated with MS and the other without it Logistic regression analysis was used to identify potential risk factors for PAD and MS and their combination.Results A total of 1365 adult Kazakh people were surveyed. Prevalence of MS was 23.7 percent, 30.4 percent for men and 19.0 percent for women, respectively, and that of PAD was 9. 4 percent, 7.0 percent for men and 11.0 percent for women, respectively. Mean age in patients of PAD complicated with MS was older than that in those without MS (t=-5.348, P＜0.01). Risk of PAD complicated with MS in Kazakh people associated with gender ( men), age, systolic pressure, diastolic pressure and blood glucose level.(P＜0.05). Conclusions Both prevalence of PAD and MS are significantly higher among Kazakh people in Yili prefecture of Xinjiang, and increase with age. Prevalence of PAD is significantly higher in those with MS than that in those without MS. Risk factors of PAD complicated with MS include gender(men), age,systolic pressure, diastolic pressure and blood glucose level.

BACKGROUNDThe extent of pulmonary resection is decided by the location and extent of the tumor and the patient's physiologic ability to tolerate resection. Bronchoplastic and pulmonary arterioplastic procedures have become increasingly popular in recent years as an alternative to pneumonectomy. In this article our experience with arterioplastic and bronchoplastic procedures in the treatment of central-type bronchogenic carcinoma was reviewed.

METHODSFrom October 1999 to October 2005, 12 pulmonary arterioplasties and 14 combined broncho-angioplasties were performed for bronchogenic carcinoma and meanwhile two replacement of vena cava were done.

RESULTSOf the 26 patients, 18 were in stage II and 8 were in stage III. No fatal surgical complications occured. Atelectasis occurred in 2 patients (7.7%), postoperative pneumonitis in 2 (7.7%), and reperfusion lung injury in one (3.8%). The 1-and 3-year survival rates for the entire group were 100.0% and 69.2% respectively.

CONCLUSIONSPulmonary arterioplastic and broncho-angioplastic procedures can be performed safely. Angioplastic and combined broncho-angioplastic procedures offer patients with bronchogenic carcinoma similar a long-term result as radical lung resection, especially in patients who cannot tolerate pneumonectomy due to poor cardiopulmonary reserve.

We constructed different N-terminal truncated variants based on Bacillus acidopullulyticus pullulanase 3D structure (PDB code 2WAN), and studied the effects of truncated mutation on soluble expression, enzymatic properties, and application in saccharification. Upon expression, the variants of X45 domain deletion existed as inclusion bodies, whereas deletion of CBM41 domain had an effective effect on soluble expression level. The variants that lack of CBM41 (M1), lack of X25 (M3), and lack both of CBM41 and X25 (M5) had the same optimal pH (5.0) and optimal temperature (60 degrees C) with the wild-type pullulanase (WT). The K(m) of M1 and M5 were 1.42 mg/mL and 1.85 mg/mL, respectively, 2.4- and 3.1-fold higher than that of the WT. k(cat)/K(m) value of M5 was 40% lower than that of the WT. Substrate specificity results show that the enzymes exhibited greater activity with the low-molecular-weight dextrin than with high-molecular-weight soluble starch. When pullulanases were added to the saccharification reaction system, the dextrose equivalent of the WT, M1, M3, and M5 were 93.6%, 94.7%, 94.5%, and93.1%, respectively. These results indicate that the deletion of CBM41 domain and/or X25 domain did not affect the practical application in starch saccharification process. Furthermore, low-molecular-weight variants facilitate the heterologous expression. Truncated variants may be more suitable for industrial production than the WT.

OBJECTIVETo evaluate the efficacy and safety of bone marrow-derived mesenchymal stem cells (MSC) from a third party donor for secondary poor graft function (PGF) following allogeneic hematopoietic stem cell transplantation(allo-HSCT).

METHODSFive patients with secondary PGF were treated with MSC at a dose of 1 x 10(6)/kg body weight at a median of 47 days (35 to 61) after secondary PGF. MSC were derived from bone marrow (BM) of HLA-disparate third party donors, cultured in vitro and infused without HSC. If absolute neutrophil cell (ANC) and platelet counts (PLT) did not reach the standardization of > 1.5 x 10(9)/L and > 50.0 x 10(9)/L, respectively, within 28-30 days after the first MSC treatment, a second MSC treatment was required.

RESULTSMSC were infused once in one patient and twice in four patients with an interval of 28 to 30 days. All patients obtained ANC and PLT recovery at a median of 34 (25 to 49) days and 47 (26 to 54) days, respectively, without toxic side effects within follow-up periods of median 761 (204-1491) days. Three patients developed Epstein-Barr virus (EBV) reactivation at 42, 48, 108 days after MSC infusion, respectively and two of the three coverted to posttransplant lymphoproliferative disorders (PTLD).

CONCLUSIONMSC from a third party donor are effective to patients with secondary PGF following allo-HSCT, whether it might increase the risk of EBV reactivation and EBV-associated PTLD need further observation.

OBJECTIVETo explore the effect of mesenchymal stem cells (MSCs) on refractory acute graft-versus-host disease (GVHD) failed to second-line immunosuppressive therapy.

METHODSTwenty-two patients with refractory aGVHD received the treatment of first- and/or second-line immunosuppressive agents in combination with MSCs. The MSCs from bone marrow (BM) of HLA-unrelated third-party donors, were used at the median time of 19 (11 - 49) days after aGVHD onset, at a dose of 1×10(6)/kg once with an interval of 14 days. If the symptoms of aGVHD did not improve after continuous infusion four times, MSCs would be discontinued. Meanwhile the proportion of CD3(+)CD4(+), CD3(+)CD8(+) and CD4(+)CD25(+) was detected by flow cytometry (FCM) before and 4 weeks after the MSCs infusion.

RESULTSThe median dose of MSC was 4.8 (2.5 - 6.3)×10(6) cell×kg(-1) with a median infusion of 2.5 (1 - 7) times per case. Twelve patients achieved complete response (CR), four partial response (PR) after treatment. The total effective rate was 72.7% (16/22). With a median follow-up of 246.5 (36 - 1116) days post-transplantation, 11 patients survived and 11 died. The causes of death included GVHD(n = 6), infections (n = 3), leukemia relapse (n = 1) and post-transplant lymphoproliferative diseases (n = 1), respectively. The proportion of CD3(+)CD4(+)/CD3(+)CD8(+) was significantly higher at 4th week after MSCs infusion compared to before infusion (1.58 ± 0.54 vs 0.49 ± 0.19, \%t\% = 0.628, P = 0.04). The number of CD4(+)CD25(+) Treg cells had not changed much compared to before infusion (P = 0.606).

CONCLUSIONMSCs derived from the BM of a third-party donor are effective to treat aGVHD failed to second-line immunosuppressive therapy after allo-HSCT. MSCs might play a role in aGVHD by regulating the rate of CD3(+)CD4(+)/CD3(+)CD8(+).

OBJECTIVETo investigate the effects of citicoline on spatial learning and memory of rats after focal cerebral ischemia.

METHODSThe rats were randomly divided into sham-operation group, ischemia control group and citicoline group. In the later two groups, focal cerebral ischemia model was established by introducing an intraluminal filament into the left middle cerebral artery, and citicoline (500 mg/kg) or 0.9% NaCl was administered intraperitoneally once a day for 2 weeks after the operation. The rats in the sham-operation group were not subjected to middle cerebral artery occlusion (MCAO) with intraluminal filament. The spatial learning and memory functions of the rats were evaluated by Morris water maze test 15 days after MCAO for 5 days.

RESULTSThe rats in ischemia control group exhibited serious spatial learning and memory deficits in both place navigation test and spatial probe test. In the former test, the mean escape latency of citicoline-treated rats were significantly shorter than that of ischemia control rats (P<0.01), and in the latter test significant diffidence was noted between citicoline and ischemia control groups in the percentage time spent in the former platform quadrant and frequency of crossing the former platform (P<0.05).

CONCLUSIONCiticoline can improve the spatial learning and memory function of rats after focal cerebral ischemia.

OBJECTIVETo evaluate the accuracy and practicability of detecting viable myocardium by CARTO voltage mapping in swine model of acute myocardial infarction (MI).

METHODSMI was induced in 13 anesthetized swines via occluding the distal of left anterior descending coronary arteries by angioplasty balloon for 60-90 minutes. The viable myocardium detection by CARTO voltage mapping was made after reconstruction of the left ventricle using CARTO and the results were compared with TTC staining. The standard of CARTO voltage to detect viable myocardium was 0.5 - 1.5 mV while viable myocardium showed pink color by TTC staining.

RESULTSEleven out of 13 swines survived the operation and 2 swines died of ventricular fibrillation at 45 and 65 minutes post ischemia. Left ventricle was divided into 16 segments and 176 segments from 11 swines were analyzed. Viable myocardium detected by CARTO voltage mapping was identical as identified by TTC staining (Kappa = 0.816, P < 0.001). Taken the TTC result as standard, the sensitivity, specificity and accuracy rate of CARTO voltage mapping are 71.8%, 96.5% and 90.9% respectively.

CONCLUSIONCARTO voltage mapping could be used as a reliable tool to detect viable myocardium in this model.
