Objective To study the prothrombotic state ,the factors leading to this status,and its relation-ship with the risk of cardiovascular disease in impaired glueese tolerance (IGT) patients. Methods The patients were divided into 4 groups : ①20 control subjects, ②38 patients with IGT, ③20 patients with diabetes only,④31 with diabetes and coronary heart disease. The vWF, throbomodulin, protein C, protein S, plasminogen activator inhibi-tor 1 were measured by ELISA. Results ①)There was statistical difference between IGT and controls in vWF, activi-ty of PC and PAI-1 (P <0.01 ,respectively). ②There were different factors that probably lead to the prothrombotic status among patients with IGT and diabetes. ③There were statistical differences among IGT, diabetes and diabetes with coronary heart disease in vWF, activity of Protein C. There were statistical difference among IGT , diabetes and diabetes with Coronary heart disease in PAI-1 (P < 0.05,respectively). Conclusion ①There is the prothrombotic status in the patients with IGT, similarly to those with diabetes.② IGT has the similar prethrombotic status as diabe-tes, So IGT could be considered as the predromal stage of diabetes, because of some continuity in the progress. Mean-while,it still has some different specialties. ③The abnormality of the system of endothelium, anti-coagulation and fi-brolysis in the patients of IGT is similar to those with diabetes. These variations might have the similar risk of cardio-vascular disease with the diabetes.

Objective To investigate the change of cognitive function in the elders with first acute ischemic brain stroke.Methods The cognitive function was determined using senile cognitive function(SECF) scale in 110 senile patients with first ischemic brain stroke and 60 healthy elders.According to different sites of cerebral infarction identified by CT imaging,their cognitive functions were compared,respectively.Results The cognitive function obviously decayed in the elders after the first acute ischemic stroke and had the relation with age and site of the infarction.Conclusion The elders with first ischemic stroke have obvious disorder of cognitive function and could directly influence the recoveries of the patients.So,the therapy should include both somatic and cognitive function treatment.

Objective To evaluate the effects and possible mechanism of endovascular irradiation using liquid 32 P-filled ballon catheter on restenosis after interventional therapy.Methods 54 Wistar rats were randomly divided into injured group, which received the balloon injury of thoracic aorta, and irradiated group, which received the balloon injury of thoracic aorta followed immediately by ionizing radiation using 20 Gy or 28 Gy liquid 32 p-filled balloon catheter. The expressions of proliferation cellular nuclear antigen(PCNA) in vascular cells and smooth muscle actin(?-SM actin) in the vascular adventitia were detected by immunohistochemical method, and were quantified by computer image analysis. The morphologic changes of thoracic aorta were analyzed by computer image analysis . Results ⑴14 days after injury, both the lumen area and external elastic lamina (EEL) area of thoracic aorta in the irradiated group were significantly larger than those in injuried group, but the neointima area was significantly smaller in the irradiated group. The above chanages were negative relation with the irradiation doses. ⑵At third day after injury, the cell proliferation activity in the adventitia and media of thoracic aorta in the irradiated group obviously decreased in dose dependent manner compared with the injured group. At the 7th day after injury,there was not significant difference in the cell proliferation in the adventitia and media of the vessels between the irradiated group and injury group. ⑶At 7th and 14th days after injury. The ?-SM actin expression level in the adventitia of thoracic aorta in the irradiated group was significantly lower than that in the injured group, which was negatively related with the irradiation dose.Conclusion To some extent, there was a correlation between the irradiation dose of using liquid 32 p-filled balloon catheter and the areas of lumen, EEL and neointima. The endovascular irradiation could contribute to inhibiting the neointima and improving the vascular remodeling by inhibiting vascular cell proliferation and adventititial ?-SM actin expression.

Objective To investigate the effect of deproteinated bone(DPB)-bone morphogenetic protein(BMP) complex on bone tunnel enlargement after anterior cruciate ligament reconstruction in rabbits.Methods A total of 96 adult New Zealand white rabbits were used in this study,and divided into 4 groups.In each group,we reconstructed the anterior cruciate ligaments of the animals using semitendinosus autograft.After the operation,DPB-BMP complex,DPB,or BMP was implanted into the femoral bone tunnel of the rabbits in three of the 4 groups.Another group that received neither DPB nor BMP served as a control.In 4,8,12,or 16 weeks after the implantation(6 rabbits in each group at each time point),we killed the animals to obtain the specimens of the femoral bone tunnel.Then the width of the tunnel was measured,and the percentage of its enlargement was calculated.Results In the DPB+BMP,DPB,BMP,and control groups,the bone tunnel was enlarged by(23.52?0.43)%,(34.83?0.52)%,(51.57?0.76)%,and(56.90?0.81)% in 4 weeks,(22.21?0.34)%,(35.35?0.46)%,(60.97?0.63)%,and(67.18?0.70)% in 8 weeks,(21.94?0.37)%,(33.01?0.41)%,(50.56?0.54)%,and(54.61?0.55)% in 12 weeks,and(20.96?0.35)%,(32.11?0.50)%,(49.29?0.66)%,and(53.31?0.59)% in 16 weeks,respectively.The rates of bone tunnel enlargement in the DPB+BMP group was the lowest at each time point(DPB+BMP group

Objective To investigate the features of HIV-1-specific Cytotoxic T-Lymphocyte (CTL)responses in Chinese.Methods The HIV-1-specific CTL responses were analyzed in an IFN-?ELISPOT assay by using a matrix system containing 820 overlapping peptides spanning the entire HIV-1 Clade B and C consensus sequence.Results The HIV-1-specific CTL response almost clus- tered in Gag and Nef across either HIV-1 Clade B(HIV-1 B)or HIV-1 Clade C(HIV-1 C),while oth- er proteins could also be recognized at different level.In comparison of the response between HIV-1 Clade B and Clade C,the magnitude and frequency was roughly identical with some difference found at single-peptide level.The most frequently recognized peptides of HIV-1 B were located in Nef,GPKEP- FRDYVDRFYKTLR(5/17,29.4%)and Gag,LWVYHTQGYFPDWQNY(5/17,29.4%),while the most frequently recognized peptide of HIV-1 C was located in Gag GPKEPFRDYVDRFFKTLR(6/17, 35.29%).Conclusions HIV-1-specific CTL responses clustered within HIV-1 Gag and Nef in Chinese. However,there was some difference between HIV-1 B and HIV-1 C at single-peptide level.

Objective To analyze the cognition, utilization and satisfaction on pregnancy health management of basic public health services. and to find out potential problems and provide suggestions for promoting equality in rural basic public health. The Weishan Lake area was selected as the sample point and the left behind pregnant women in the countryside as control. Methods In the period from May 2016 to July, questionnaires were designed for the pregnancy health management of basic public health services, 330 left-behind pregnant women and 300 rural immigrating pregnant women were selected as our target interviewees. The average age of rural immigrating pregnant women and the left-behind pregnant women was (28.6 ± 3.7) years, and (28.3 ± 3.4) years old, respectively; the degree of education of rural immigrating pregnant women and the left-behind pregnant women was secondary specialized school or high school and junior middle school, respectively. The occupation of rural immigrating pregnant women was mainly workers;accounting for 31.4%, while the occupation of the left-behind pregnant women was farming, accounting for 36.7%. Results The awareness rate ofgeneral pregnancy examination and gynecological examinationin health management items of rural immigrating pregnant women and left-behind pregnant women was the highest, which were 77.7% and 78.3%, respectively, and the lowest awareness rate of the 2 prenatal follow-up was the lowest in the third trimester, which was 22.6% and 23.0%, respectively. The difference was not statistically significant. The maternal health management service understanding rate of rural immigrating pregnant women and left-behind pregnant women were 24.7% and 17.9% respectively , the difference was statistically significant (Z=-1.993, P=0.046);the awareness rate of delivery and breastfeeding in late pregnancy were 36.2% and 47.6% respectively, and the difference was statistically significant (χ2=7.933, P=0.005). The rate of the registering of the maternal health care handbook of rural immigrating pregnant women and left-behind pregnant women were 40.4%and 54%respectively, and the difference was statistically significant (χ2=11.065, P=0.001), Among them, the rate of registering in township hospitals was 46.6% and 73.3% respectively, and the difference was statistically significant (χ2=21.104, P=0.0000); the utilization rate of 3 or more antepartum examination and follow-up services was 8.4%and 23%respectively, and the difference was statistically significant (χ2=23.878, P=0.000). The growth and development of the health of pregnant women and fetal assessment and utilization rates were 9.8% and 23.6%, the difference was statistically significant (χ2=20.460, P=0.000); prenatal guidance (childbirth preparation, breastfeeding) utilization rate were 8%, 13.7%, the difference was statistically significant (χ2=5.011, P=0.027);abnormal or critical maternal referral utilization rate were 22%and 34.8%, the difference was statistically significant (χ2=12.133, P=0.001). Conclusion Imbalance exists in acquiring basic public health services of the two pregnant women cohort, the left-behind pregnant women are better than the rural immigrating pregnant women. Therefore, the government should propagate this service by multi-channel to improve their cognition and utilization of this policy implemented, and to promote the development of the services.
