Objective To explore the association of SDF1 3A genetic polymorphism with susceptibility of essential hypertension and captopril efficacy in patients with essential hypertension.Methods A total of 214 patients with essential hypertension and 228 healthy controls were genotyped for SDF1 3A polymorphism by polymerase chain reaction-restriction fragment length polymorphism assay. Among 39 subjects with different SDF1 3A of genotypes, 13 hypertensive patients simultaneously took oral captopril (25 mg/d) and nitrendipine (30 mg/d), and 12 patients orally received nitrendipine alone for 8 consecutive weeks, and 14 healthy controls did not take any agents. The blood pressure of all subjects was measured to evaluate the therapeutic efficacy. Results There was a significant difference in the plasma SDF-1 level in individuals with AA+AG genotypes or GG genotypes of SDF1 3A treated with nitrendipine plus captopril compared with healthy control (P<0.05). Carriers with AA genotypes of SDF1 3A had lower total protein and globulin than those with GG genotypes (P<0.05). After captopril treatment, hypertensive patients with AA+AG genotypes had bigger attenuated systolic blood pressure compared with those with GG genotypes (P<0.05). Conclusion Genetic polymorphism of SDF1 3A could influence the therapeutic efficacy of captopril in Chinese hypertensive patients.

Complement system is an important component of innate immunity and has been recognized as an effective means to inhibit tumor. However,in last decades,accumulating studies showed unexpected results that the complement components and their activation products could promote development of malignancies by secreting growth factors,activating signal pathway and promoting tumor angiogenesis. Herein,the relationship between the complement system and tumor is reviewed.

Objective To evaluate the curative effects of intravenous methylprednisolone (IVMP) during the conservative management for patients with indirect optic nerve injury (ONI),and to analyze the benefits of visual evoked potential (VEP) monitoring in prognosis assessment.Methods Among the 253 patients with cranial-facial injury,108 sufferred from optic nerve injury including 89 cases without optic nerve decompression treatment.These 89 patients were randomly divided into:group A,in which patients were given methylprednisolone intravenously for 7 days; and group B,in which patients without methylprednisolone treatment.The extent of and time required for eyesight recovery were recorded.VEP measurement was carried out in all cases.Results No differences in gender,age and BMI (Body Mass Index,all P ＞ 0.05) were observed.The incidence of ONI was higher in patients with motorcycle accident than that in those with car accident (P ＜0.01).In the motorcycle accidents,casualties wearing a helmet had lower incidence of ONI (P ＜ 0.01).Patients treated with methylprednisolone had a shorter recovery time (P ＜ 0.01) from blindness,however there was no difference in long-term outcome between group A and B.In patients with visual improvement in the “ non-extinguished” group,the amplitude and latency of the P wave of VEP were markedly ameliorated after the treatments (P ＜ 0.01).Conclusions Most of the ONI casualties in our study were resulted from motorcycle accidents,and wearing a helmet is an effective protection measure.The intravenous methylprednisolone (IVMP) showed no effect on improving the prognosis in patients with conservative treatment.The IVMP shortened the recovery time at the expense of increase in risk of complications.VEP examination is beneficial in prognosis assessment for non-operative ONI patients.The improvement of the amplitude and latency of P wave has close correlations with patients'visual recovery.

Objective Adverse reactions to Gd-DTPA contrast media should be noticed enough.Methods Three cases of adverse reactions to Gd-DTPA contrast media were studied, and literatures were reviewed.Results The rate of adverse reactions to Gd-DTPA contrast media in our hospital was 0.206%.Conclusion Although the rate of adverse reactions to Gd-DTPA contrast media is very low, this problem must be noticed enough with the medical quality’s developement.

Objective To explore the impact of advanced glycation end-products ( AGEs) on matrix metalloproteinase 2 ( MMP-2) expression in cultivated INS-1 cells. Method INS-1 cells were cultivated and MMP-2 expression was analyzed. Glycated serum was prepared for incubating with INS-1 cell. Reactive oxygen species (ROS) was detected by flow cytometry. The intracelluar MMP-2 expression was analyzed by RT-PCR, realtime PCR and Western blot. The MMP-2 cDNA was expressed in cultivated INS-1 cells. Result The level of ROS treated with AGEs was significantly higher than that in the control( P<0.05 ) , and the levels of MMP-2 and its protein expressions turned out as well( P<0. 05). Conclusion The results suggest that MMP-2 was expressed in INS-1 cells. Increased MMP-2 expression in ?cells may be induced by AGEs, suggesting that MMP-2 might play an important role in oxidative stress-mediated islet injury.

As one of the chronic disease of respiratory system,chronic obstructive pulmonary disease contributes to a progressive decline of lung function,as well as the extra-pulmonary effects.Malnutrition,one of the extra-pulmonary effects,becoming the common problem for chronic obstructive pulmonary disease patients.It has severe harm to chronic obstructive pulmonary disease patients that need us to pay more attention to it.The choice of nutrition assessment tools has important significance for the correct results of nutrition status of the patients.

Objective To explore the effect of Eight-Section Brocadeon improving extrapulmonary performance and lung function in elderly stable chronic obstructive pulmonary disease (COPD) patients. Methods A total of 120 elderly stable COPD patients were divided into experimental group and control group by random digits table method with 60 cases each. The experimental group received Eight-Section Brocade and the control group took a walk both based on the routine health education. The World Health Organization Quality of Life (WHOQOL)-BREF, 6 min walking test and lung function were conducted before and after intervention 12, 24 and 36 weeks. Results After intervention, the score of each field of WHOQOL-BREF were higher than those before intervention, comparison of two groups of physiological fields Ftime=57.112, Fgroup=10.510, Finteractive=13.653, all P<0.01; psychological field Ftime=240.209, Fgroup=6.201, Finteractive=6.902, all P<0.05;field of social relations Ftime=34.957, Fgroup=7.265, Finteractive=11.554, all P<0.01; environmentfield Ftime=66.431, Fgroup=8.197, Finteractive=18.413, all P<0.01, and there were significant differences in time, groups and interactive. Comparison of two groups of the result of 6 min walking test after intervention, Ftime=327.697, Fgroup=37.181, Finteractive=61.420, all P<0.01. Comparison of two groups of the result of lung function indexforced expiratory volume in one second, Fgroup=5.083, P<0.05, there was significant difference;after intervention the index of Forced expiratory volume in 1 second take up of the expected value, Fgroup=4.141, P<0.05, there was significant difference. Conclusions Eight-Section Brocade can effectively improve the elderly stable COPD patients with exercise endurance and quality of life, improve the extrapulmonary performance, delay the progressive decline of lung function.

Using the high efficient copper-adsorbing yeast strain Y17 as absorbing material, the major affect factors including pH, original concentration of Cu2+, cell biomass, adsorption time and temperature were examined, and then the absorbing sites of the Y17 was determined. The results showed that the solution pH was the most dominate factor which affected the biosorption of Cu2+, the other affecting factors were the ini- tial concentration of Cu2+, the cell biomass added, and adsorption time, respectively; the temperature had lit- tle effect on the rate of biosorption. The orthogonal experiment showed that the optimal absorption condition was as follow: the solution pH was 5.0, the absorption time was 40 min, the cell biomass of Y17 added was 5.0 g/L, and the concentration of Cu2+ was 8 mmol/L; the highest adsorbing rate was up to 82.7% at this condition. Based on the results of different pretreatments and the desorption of Cu2+, the cell wall of Y17 was identified as the main place occurring boisorption process, and the -NH2 group, -COOH group on the surface of the yeast cells played an important role on the boisorption process.

Cognitive dysfunction is one of the complications of chronic obstructive pulmonary disease(COPD),often affecting the patient's daily life ability and reducing the quality of life.COPD associated cognitive dysfunction includes five areas of primary cognitive domain of awareness,attention,learning and memory ability,execution ability and language skills.The decreased cognitive dysfunction may be correlated with the age,education background,smoking,malnutrition,as well as hypoxemia,hypercapnemia,COPD duration and length of hospitalization stay,inflammatory and other factors.Early screening and assessment of COPD cognitive dysfunction,long-term oxygen therapy and other measures for interfering risk factors and improving the quality of life of patients have a positive significance.
