Objectives To grasp the situation and fluctuation tendency of Keshan disease in Qujing City,and to scientifically evaluate the control effect of Keshan disease.To provide scientific basis for elimination of Keshan disease in the 12th Five-Year Plan.Methods Cardiomyopathy cases of the past three years were searched,screening suspected cases of Keshan disease.And according to the National Surveillance Program of Keshan Disease (Trial),In Qujing City,2 Keshan disease counties (Huize,Qilin) were selected to carried out focused monitoring,1-2 endemic townships with more patients were selected based on total numbers of cases in each county,1 village with more patients was selected in each township as a monitoring site,the residents of the monitoring sites were examined clinically and electrocardiographic (ECG) tracings recorded and suspicious patients were taken chest radiograph and color Doppler ultrasound echocardiography.Diagnosis was based on the Diagnostic Standard for Keshan Disease.Results Totally 300 cases of cardiomyopathy were found,10 cases were suspected Keshan disease,0 cases of Keshan disease was diagnosed in 2009-2012.In the three villages of the two counties monitored,3 cases of potential Keshan disease were detected of the 1 505 villagers,the detection rate was 0.20％;62 abnormal ECG were found,the abnormal rate was 4.12％.Chest X-ray examination was done in 3 people,cardiothoracic ratio of 0.50 or less were 2 people,and 0.51-0.55 was 1 person.Conclusion The prevalence of Keshan disease in Qujing City is low,but the pathogenesis of Keshan disease remains,therefore,monitoring and intervention of children Keshan disease should be strengthened.

Objective To explore the relationship between the plasma membrane glycoprotein ( PC-1 ) gene and obesity, type 2 diabetes mellitus, insulin resistance in Chinese population. Methods 53 norma1 subjects, 105 simple obesity subjects, 63 type 2 diabetic patients and 114 obesity type 2 diabetics have been genotyped with PCR-RFLP. Results The frequency of PC-1 gene Q allele was 3%, 18%, 4% and 30% in control, obesity subjects, diabetic patients and obesity diabetic individuals, respectively. Compared with control group, the relative risk (RR) in OB group, OBH grop, OBI group, OBL group and OBHIL group was 4. 26,4. 12,7. 36,5. 15 and 9. 70, respectively. Compared with diabetes group, the RR in diabetes with DMOB, diabetes with OBH group, diabetes with OBI group, diabetes with OBL group and diabetes with OBHIL group was 5.23,7. 37,12. 07,8. 53 and 13. 50, respectively. Concluision The frequency of PC-1 gene Q allele were significantly associated with obesity, obesity diabetics and insulin resistance in Chinese. The results suggested that the PC-1 gene Q allele was a potential genetic marker for obesity, type 2 diabetes and insulin resistance.

Hypoxic-ischemic encephalopathy (HIE) is the main reason of causing neonatal death and poor prognosis of the nervous system.The treatment of HIE has gone into the era of therapeutic hypothermia,the early,continuous,specification amplitude integrated electroencephalography(aEEG) monitoring for therapeutic hypothermia to screen appropriate cases,assess early the severity of HIE,provide early nerve protection treatment and evaluate the therapeutic efficiency,early intervention and improve the prognosis of the long-term HIE.This paper review the application of aEEG in the therapeutic hypothermia of HIE.

Objective To investigate the effects of paeonol on renin-angiotensin system (RAS) occurred on the development of ventricular remodeling after acute myocardial infarction (AMI) in rats. Methods The left anterior descending coronary artery was ligated to establish the model of AMI in male SD rats. Six groups were set up:sham-operation group, AMI model group, captopril control group, paeonol low dose group (6 mg/kg), paeonol middle dose group (9 mg/kg) and paeonol high dose group (12 mg/kg). Rats were given treatment for 4 weeks after the AMI model was established. HE staining was used to observe changes of myocardial tissue. Real-time PCR was used to detect the mRNA levels of angiotensinogen (AGT), angiotensin Ⅱ receptor type1(AGTR1) and endothelin (ET)-1 of six groups. Western blot assay was used to detect the protein levels of peptidyl-dipeptidase A (ACE), angiotensin Ⅱ(Ang)-Ⅱand AGTR1 in six groups. Results The transcription of AGT, AGTR1, ET-1mRNA and the expressions of ACE, Ang-Ⅱ and AGTR1 protein were significantly higher in myocardial tissue of AMI rats than those of sham-operation rats (P＜0.05). Compared with model group, the expressions of AGT, AGTR1, ET-1mRNA and ACE, Ang-Ⅱ, AGTR1 protein were significantly decreased in paeonol high dose group and captopril control group (P＜0.05). Paeonol reduced the expressions of those mRNA and protein levels in a significant dose dependent manner. Conclusion Paeonol can slow down the deterioration of the ventricular remodeling after AMI in rats, which may be related to the inhibition of over-activation of RAS.

Objective To carry out a taxonomic identification of a strain of claviform bacteria iso-lated from prostatic fluid of a patient who suffered from chronic prostatitis, and to approach its phylogenic and biologic position. Methods We undertaked an initial identification by phenotypic characters such as morphologecal, physiological and biochemical characteristics to ascertain its phylogeny by chemical composi-tion analysis of cell wall and 16S rRNA gene sequencing and alignment. Results A club-shaped gram posi-tive rod bacillus was isolated in pure culture state. Its biochemical reactions were not active. The diamino-acid of cell wall was meso-diaminopimelic acid (meso-DAP) and it had wall chemotype Ⅳ ( contained arabi-nose, galactose and maltose ). Sequence searches of the GenBank database revealed that this strain had a highest level of 16S rDNA sequence similarity (99.4%) to C. tuberculostearicurn strain ATCC35692 with only 8 nucleotides difference. Conclusion On the basis of phenotypic and phylngenetie analysis, it is rea-sonable to assign this strain to the species C. tuberculostearicum, and this is the first isolation of C. tubercu-lostearicum from prostatic fluid home and abroad.

Objective To explore the influence of studying in the elderly university on the cognitive function for elderly. Methods Elderly university group (EUG) was consised of 105 subjects aged ≥60 who studied in the elderly university for one year. Controlled group(CG) was consisted of 105 elderly over 60 years of age who were siblings for subjects and would not studied in elderly university. Meanwhile, it was excluded if they were working. Two groups were excluded depression patients before study. The assessment tools were composed of Center for epidemiological survey of depression scale (CES-D), activity of daily living scale(ADL), mini-mental state examination (MMSE)and Wechsler's adult intelligence scale(WAIS). There were no significant statistics difference in scales of CES-D, ADL, MMSE and WAIS between two groups. Results There were no significant statistics difference of CES-D, ADL and MMSE between two groups after a year, however, the scales of ADL for controlled group after one year was higher than that before one year( t = 2. 191, P = 0.031 ). The MMSE mark shows one(0.95% )sustain cognitive impairment in EUG after one year; meanwhile there were six elders of (5.77%)come up to critical value of cognitive impairment in CG, the difference was almost statistical significance (P=0. 058 ). The WAIS mark demonstrated the total scale, VQ scale and PQ scale was declining. The score of total scale and perform scale of WAIS in CG were (110.3 ±8.2 )and (110.9 ±7.7) respectively. The score of total scale and perform scale of WAIS in CG were ( 107.8 ± 9.6 ) and ( 107.9 ± 13.4 ) respectively. There were significant difference between two groups(P=0. 044, P=0. 049). Furthermore, after one year the score of total scale of WAIS in CG( 110. 6 ± 7.4 ) outstanding be lower than that one year ago(P = 0. 022 ). There was no significant means for the total scale , verbal scale and perform scale of WAIS in CEG before and after year.Conclusion The program of continue education may play a positive role to stay or to improve the descending of the cognitive function in the elderly.

Objective To investigate the risk factors of surgical site infection ( SSI) in adult patients undergoing major heart surgery, and to provide the reference of controlling the development of SSI. Methods A case-control study was conducted with 54 SSI patients underwent major heart surgery from January 2001 to December 2009 in the case group and 162 controls in the control group. Univariate and multivariate conditional logistic regression analysis were used to analyse the risk factors of SSI development Results Univariate conditional logistic regression showed the risk factors for the development of SSI were left ventricular ejection fraction ( LVEF) < 50% (odds ratio ( OR) = 2.134,95% C/: 1.095 - 4. 159, P = 0. 026) , heart function New York Heart Association classification (NYHA) ≥Ⅲ grade, (OR =2. 390,95% CI: 1. 218 -4. 690; P = 0. 011) .diabetes (OR=3.275, 95% CI: 1.391 - 7. 708; P = 0.007), chronic obstructive pulmonary disease (COPD) ( OR = 5. 408,95% CI: 1.248- 23.445,P = 0.024),extracorporeal circulation time>90 mins ( OR =3. 045,95% CI: 1.540 - 6.024, P = 0. 001 ) , operation time > 4 h ( OR = 3. 281, 95% CI: 1. 610 - 6. 685, P = 0.001 ) , blood product consumption >2 u ( OR = 1. 929,95% CI; 1. 018 -3. 675;P =0. 044) .incision continuous suture close ( OR = 2.344,95%CI: 1.221 -4.498;P =0.010) exploration for bleeding (OR =6. 625,95%CI: 1.597-27.491 ;P =0. 009) , postoperative hyperglycemia (OR = 3. 510,95%CI:l. 5% -7. 718;P =0. 002) ,the stay in intensive care units (ICU) > 72 h ( OR = 3. 281,95% CI: 1. 505 - 7. 150;P = 0. 003). Multivariate analysis showed 3 variables increased with the risk of SSI: operation time >4h (OR = 3. 100,95% CI: 1.470 - 6. 537,P = 0.003 ) , incision continuous suture close (OR =2. 340,95% CI: 1. 183 - 4. 692, P = 0. 015 ) , and postoperative hyperglycemia (OR = 3. 272,95% CI:1.427 -7. 505,P=0. 005 ). Conclusions This study shows that the operation time >4 h, incision continuous suture close and postoperative hyperglycemia are risk factors most likely associated with SSI development in major heart surgery.

Objective To study the characteristics and clinical significance of the coronary plaques in patients with benign prostatic hyperplasia (BPH).Methods A total of 91 patients undergoing coronary artery angiography (CAG) were selected and divided into two groups according to with or without BPH,56 cases in BPH group,46 cases in control group.The qualitative and quantitative characteristics of 102 lesions area were analyzed by intravascular ultrosound (IVUS),including external elastic membrane-cross-sectional area (EEM-CSA),minimal lumen area (MLA),plaques area (PA),plaques burden (PB),reference external elastic membrane-cross-sectional area (REEM-CSA),reference minimal lumen area (RMAL),reference plaques area (RPA) and reference plaques burden (RPB).Results IVUS showed a higher rate of area stenosis than did the CAG [(58.2± 7.1)％ vs.(55.9 ± 5.2)％,P＜0.01].BPH group had more soft plaques,eccentric plaques,positive remodeling and less calcified than did the control group (P＜0.05).The MLA and RMAL of BPH group were smaller than those of control group:MAL [(5.61±0.96) mm2 vs.(6.06±0.75) mm2,P＜0.05],RMAL[(9.26±1.05) mm2 vs.(10.02±1.10) mm2,P＜0.05]； while the EEM-CSA,PA,PB,RPA,RPB were larger than those of control group:EEM-CSA[(14.51±1.10)mm2 vs.(13.37±1.02)mm2],PA[(8.90±1.24) mm2 vs.(7.31±1.04) mm2],PB[(61.26±6.53)％ vs.(54.53±5.69)％],RPA[(4.26±1.15) mm2 vs.(3.73±1.33) mm2],RPB [(31.30±8.37) ％ vs.(26.81±8.75) ％,P＜0.05].Conclusions IVUS has a higher value on evaluation of mild to moderate coronary artery stenosis.Evidence of myocardial ischemia in patients with BPH needs further excludeing coronary heart disease.

To investigate the inhibitory effects of Ginsenoside Rb1 (GRb1) on apoptosis caused by Herpes Simplex Virus-1 (HSV-1) in Human Glioma Cells (U251),U251 cells were infected by HSV-1 at a multiplicity of infection of 5 and GRb1,GRb1+HSV-1,HSV-1 and control groups.MTT and cell apoptosis assays were used to detect the inhibitory effects of GRbl on the apoptosis of U251 cells that caused by HSV-1 infection for various concentrations of drug and virus treatments by MTT assay.We found that in the 400 μg/mL GRbl and 400 μg/mL GRbl+HSV-1 groups,MTT values were higher than control group at all times (P＜0.05).Moreover,the apoptosis rate in the 400 μg/mL GRb1+HSV-1 group was lower than the HSV-1 group (P＜0.05).These results confirmed that,at appropriate concentrations,GRb 1 could inhibit nerve cell apoptosis in HSV-1 infections.
