Objective:To detect periodontopathic bacterial DNA in atherosclerotic vascular lesions in a group of Chinese patients by using polymerase chain reaction(PCR) techniques.Methods: Ten human specimens of atherosclerotic plaque were obtained sterilely.The sclerotic lesions were blade into fine pieces and DNA was isolated from the samples.To detect Porphyromonas gingivalis(Pg),Tannerella forsythia(Tf),Aggregatibacter actinomycetemcomitans(Aa),Prevotella intermedia(Pi),Prevotella nigre-scens(Pn),Treponema denticola(Td),Campylobacter rectus(Cr),PCR amplification of bacterial 16S ribosomal DNA(rDNA) was carried out.Results: PCR assays for bacterial 16S rDNA indicated the presence of periodontal pathogens in 3 out of 10 surgical specimens.DNA of Pg were found in 3 samples,Tf was found only in one among the 3 samples and Pn was found in another sample among the 3 samples.Conclusion: The data confirm that DNA of periodontal pathogens present in atherosclerotic plaques.Pg,Tf,Pn may play a role in the development and progression of atherosclerosis in these Chinese patients.Further studies with large size samples are needed.

Objective To investigate the expressions of cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) in colonic mucosa of patients with ulcerative colitis (UC)and to analyze the relationship between them. Methods The specimens of colonic mucosa from 32 UC patients were graded according to endoscopic and histological grading standards, and specimens of colonic mucosa from 26 healthy controls were also collected. The expressions of COX-2 and 5-LOX mRNA and protein in colonic mucosa were determined using real-time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR) and immunohistochemistry. The correlation between COX-2 and 5-LOX was analyzed. Results For UC patients,10 were class 1, 19 class 2 and 3 class 3 according to endoscopic grading, whereas 19 were class Ⅰ , 9 class Ⅱ and 4 class Ⅲ according to histological grading. The expressions of COX-2 and 5-LOX mRNA in active UC patients were 81. 25% and 53.13%, respectively, and were 11.54% and 19. 23% in healthy controls, respectively, with significant differences between the two groups (all P values＜0.01). The positive expressions of COX2 and 5-LOX increased in accordance with increasing of endoscopic grading and histological grading.The levels of COX-2 and 5-LOX were 20. 08±1.17 and 37.83 ±1.48 in colonic mucosa tissues of UC patients, respectively, and 48.42 ± 1.69 and 11.28 ± 1.62 in healthy controls, respectively. There was significant difference between the two groups (all P values＜0.05). A good positive correlation was found between COX-2 and 5-LOX. Conclusions The expressions of COX-2 is closely related to 5-LOX in UC patients. Both may play a pivotal role in inflammation of UC.

Objective　To observe the influence of pre-infarction angina on ventricular function and prognosis of first acute myocardial infarction in old people. Methods　76 first acute myocardial infarction old patients was divided into two groups: angina pectoris group (n=42); no angina pectoris group (n=34). Global left ventricular function was assessed by echocardiography, arrhythmia, cardiogenic shock, heart failure, post-infarction angina and mortality was observed in hospital. Results　The rate of cardiogenic shock and heart failure and mortality was lower in angina pectoris group (33.3% vs 58.8%; 2.4% vs 23.5%), LVEF and E/A was higher in angina pectoris group (0.52±0.056 vs 0.45±0.03,0.86±0.29 vs 0.54±0.35), P<0.05. Conclusion　pre-infarction angina possesses the protecting effects on ventricular function of first acute myocardial infarction in old people, and can improve the prognosis of first acute myocardial infarction in old people.

Objective To investigate the clinical features of hypotensive maintenance dialysis patients after total parathyroidectomy with autotransplantation (TPTX + AT).Methods The consecutive patients who received TPTX + AT were enrolled between January 1,2010 and May 1,2015 in the nephrology department at the central hospital of Jiangmen.According to level of the blood pressure after TPTX + AT,the patients can be divided into hypotensive-group and non-hypotensive-group.The clinical and laboratory examinations of them were compared.Results The probability of calcification of aortic valve (4.76％ vs 30％,P =0.045),bicuspid valve (9.52％ vs 40％,P =0.032) and pulmonary hypertension (14.29％ vs 45％,P =0.043) was lower in the hypotensive-group with statistical significance.Serum parathyroid hormone [(9.31 ± 5.41) pg/ml vs (60.12 ± 96.95) pg/ml,P =0.021] and angiotensinⅡ (Ang Ⅱ) [(34.26 ± 15.73) pg/ml vs (63.78 ±23.55) pg/ml,P =0.000] were lower in the hypotensive-group with statistical significance.Serum intact parathyroid hormone (iPTH) (P =0.036) and AngⅡ (P =0.002) were the affecting factors of hypotension after TPTX + AT.Conclusions Hypotension after TPTX + AT is associated with the lower level of serum iPTH and Ang Ⅱ.The probability of calcification of cardiac valve and pulmonary hypertension is lower in the patients with hypotension,indicate that they may have better cardiac prognosis.

Postpartum inferior vena cava (IVC) thrombosis is a rare, but potentially life-threatening disorder. Here we reported one case of the youngest woman to date who presented with massive IVC thrombus extending from deep veins of the right leg to the level of the 11th thoracic vertebra, associated with asymptomatic pulmonary embolism.

Objective To establish a method for determining the content of Naringin and Hesperidin in Zengshi Keli by HPLC. Methods The Kromasil C18 column with acetonitrile-water-phosphoric acid (20∶80∶0.02) as the mobile phase was used. The flow rate was 1.0 mL/min, the detective wavelength was 283 nm, the temperature of column is 35 ℃. Results The calibration curve were linear in the range of 0.178 5～0.892 5 ?g for Naringin and 0.073 68～0.368 4 ?g for Hesperidin (r=0.999 9) respectively. The average recovery was 97.24% (RSD=1.21%) and 96.95% (RSD=1.49%) respectively. Conclusion The method was simple, accurate, reproducible and can be used for quality control of Zengshi Keli.

Objective To observe the effect of Huanglian Jiedu Decoction ( HJD) for the treatment of dyslipidemia, thus to provide evidence for the prevention and treatment of dyslipidemia with traditional Chinese medicine. Methods A total of 80 dyslipidemia patients were randomized into HJD group ( 50 cases) and simvastatin group ( 30 cases) . After treatment for 4 weeks, blood lipid levels, metabolic parameters and alanine aminotransferase (ALT) levels were detected. Results (1) After treatment, HJD group and simvastatin group both had lower total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol levels (P<0.01 compared with those before treatment), and HJD group had higher high density lipoprotein cholesterol than that before treatment ( P<0.05), but the differences of TC, TG, low and high density lipoprotein cholesterol were insignificant between the two groups ( P>0.05). ( 2) After treatment, uric acid was reduced in HJD group ( P<0.05) , but fasting blood glucose only showed a decreasing trend and the other metabolic parameters stayed unchanged ( P>0.05). The inter-group comparison showed that HJD had lower blood glucose level than simvastatin group, and the difference had statisticall significance ( P<0.05). ( 3) During the treatment, the patients showed good compliance, and had no obvious hepatic or renal damage. Conclusion HJD could reduce TC, TG and low density lipoprotein cholesterol, and increase high density lipoprotein cholesterol of dyslipidemia patients, the effect being similar to simvastatin. HJD could also significantly reduce uric acid of dyslipidemia patients, showing good safety.
