Pulmonary artery hypertension is a serious disease in respiratory system and a key tache in the mechanism of pulmonary-heart disease. The pathological changes include the contraction and remodeling of the pulmonary vessels. There are more and more studies on the pulmonary artery hypertension because of its refractory character and the following increasing mortality. This article summarizes the updating research of the factors and mechanism studied on pulmonary artery hypertension recently, to provide a new view for the clinical and basic medical investigation.

Objective Comparison the corrective effect of plasma exchange method and formula method for chylemia on hematology analysis.Methods A total of 10 samples without hemolysis,jaundice and lipemia were set as control group,each sample was divided into 4 parts,then 5,10,20 and 40 μl lipid emulsion was added.Each chylous samples was treated by plasma exchange method for two times,and routine blood test was reanalyzed with hematology analyzer.The comparisons before and after the exchange was made,while the test results on each exchange were analyzed.For another part,the HGB of chylous plasma was tested,the value was substituted into HGBcorrected value =HGBbefore correction-(HGBchylous plasma-HGBchylous plasma ×HCTbefore correction).Results The chylemia could lead significant increase of HGB,MCH and MCHC (P＜0.05).After plasma exchanging for two times,the three parameters returned to normal and the count of WBC,RBC and PLT decline slightly with no significance.There were no differences between plasma exchange method and formula calibration method.Conclusion Plasma exchange method and formula calibration method could significantly reduce the impact of chylemia on routine blood analysis,which facilitate the clinical work with correct analysis of routine blood test.

Objective To understand the prevalence and genotype distribution of human papillomavirus among male patients attending to venereal outpatient department and provide basic data for prevention and treatment of HPV.Methods Retrospective analysis method was used to analyze 1 074 patients from venereal outpatient department of Beijing Friendship Hospital during January to August in 2015.Swab specimen were analyzed by flow-through hybridization and gene chip to detect the type of HPV.Chi-square test was used to compare the distribution of CA and suspected patients.Results Among the 434 CA samples, the positive rate was 72.6%(315/434).The 58.1%(252/434) samples were high risk HPV positive and 14.5%(63/434) samples were low risk HPV positive.In high risk HPV infection, multiple infection accounted for 40.4%(175/434) and single infection was 17.7%(77/434), while in low risk HPV infection, single infection accounted for 12.9%(56/434).HPV-11, HPV-6, HPV-16, HPV-52, HPV-58 and HPV-51 were common.The positive rate among suspected CA patients was 36.6%(234/640) , and dominated in high risk HPV infection 25.3%( 162/640 ) .The positive rates of high risk HPV in CA patients [ 40.4%( 175/434 ) and 17.7%( 77/434 ) ] were obviously higher than that of suspected ones [12.9%(56/434) and 1.6%(7/434)], χ2 =95.956 and 9.122, both P<0.05.Conclusions Male patients from venereal outpatient department have a high prevalence of HPV, and common genotype are HPV-11, HPV-6, HPV-16, HPV-52, HPV-58 and HPV-51.The intensity of HPV screening should be strengthened in order to provide the vital basis for the prevention and treatment HPV related diseases.

BACKGROUND:High pulse pressure is the signal of arteriosclerosis or cardiovascular diseases for both hypertension and normal blood pressure population.OBJECTIVE:The pulse pressure and related factors of healthy adults in Sichuan province were analyzed to explore the method for preventing excessive pulse pressure and improving the quailty of life.METHODS:Hierarchical,cluster sampling were performed in 1989 healthy adults.The physical examination,blood glucose,renal function and blood fat were detected,and the relation of pulse pressure and its related factors were analyzed.RESULTS AND CONCLUSION:Pulse pressure increased following the age.especially showed a linear increasing in those who more than 50-year-old The increased pulse pressure leaded to larger fasting plasma glucose,uric acid,blood urea nitrogen,total cholesterol,triacylglycerol,systolic pressure and diastolic pressure,in addition,the age,body mass index,waist-to-hip ratio,triacylglycerol and pulse pressure showed a linear relationship.But physical exercise was negative correlated to pulse pressure.With pulse pressure increasing,the renal function and regulating capacity of blood glucose was decreased The results suggested that mid-aged population should take reasonable diet and more physical exercise to prevent central obesity and excessive pulse pressure,reduce the risk of renal dysfunction and the incidence of cardiovascular disease.

OBJECTIVETo study the treatment effects of cultured Cordyceps sinensis combined with glucocorticosteroid on experimental pulmonary fibrosis in rats induced by bleomycin.

METHODFifty rats were randomly divided into five groups, including control group, model group, cultured C. sinensis groups, prednisone group, cultured C. sinensis combined with prednisone group. On experimental day 0, the rats were respectively intratracheally instilled with bleomycin, and rats in the control group and model group with the same volume of normal saline. One day after the injection, cultured C. sinensis and glucocorticosteroid was respectively given to rats daily by gastric gavage, while the same volume of normal saline was given to those in the control group and model group. On 28th d, bronchoalveolar lavage fluid (BALF) and lung tissue were collected. Histological changes of the lungs were evaluated by HE stain, Masson's trichrome stain. Collagen content of the lung tissue was assessed by hydroxyprolin concentration. Lung expression of CTGF protein was assessed by immunohistochemistry. The level of TGF-beta1 protein was measured by ELISA.

RESULTCompared to model group, pulmonary fibrosis were alleviated in cultured C. sinensis and prednisone group, and CTGF expression, Hydroxyproline concentrations and protein TGF-beta1 were decreased. The combination effect of C. sinensis and prednisone group is augmented compared with using C. sinensis or prednisone group alone.

CONCLUSIONThe cultured C. sinensis and prednisone alleviates pulmonary fibrosis, and the combination use of both drugs has synergia effects in anti-fibrous degeneration.

Objective: To investigate the diagnostic value of serum complement level and lipid metabolism level detection in senile osteoporosis. Methods: A total of 215 elderly people who underwent physical examination and bone mineral density test in Beijing Jishuitan Hospital from January 2016 to June 2016 were divided into osteoporotic group(74) and non-osteoporotic group (141) according to bone mineral density classification. The relationship between serum complement C3, complement C4, low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), triglyceride (TG), total cholesterol (CHO) and bone mineral density were analyzed. The data were analyzed by t-test, non-parametric test, binary Logistic regression and the receiver operating characteristic (ROC) curve. Results: The age and CHO,LDL, HDL, complement C3 and C4 in the osteoporosis group[(80.6±8.2)years, (4.43±1.25)mmol/L, (2.27±0.73) mmol/L, (1.33±0.39) mmol/L, (1.12±0.22) g/L, (0.29±0.09)g/L], were significantly higher than those in the non-osteoporosis group[(77.5±8.3)years,(4.04±1.02)mmol/L,(1.97±0.59)mmol/L,(1.19±0.32)mmol/L,(0.86±0.25)g/L,(0.21±0.06)g/L,t-value were 2.571,-3.848,-4.483,-3.951,-1.249,-1.185,P<0.05], and the the BMI bone mineral density T-Score value of DXA and in the osteoporosis group were significantly lower than those in the non-osteoporosis group[(22.33±3.8)kg/m², -2.74±0.78 and (25.03±4.2)kg/m², 0.14±0.9, while the t value was 6.151 and 4.624, respectively, P<0.05]. The level of TG in osteoporotic group was significantly lower than that in non-osteoporotic group[the median (quartile) was 1.21(0.67,1.44)mmol/L and 1.37(0.86,1.67)mmol/L, respectively, Z=-2.51, P<0.01].Gender and serum levels of HDL, LDL, C3 and C4 were independent risk factors for senile osteoporosis(OR=2.476,P=0.004;OR=1.305,P=0.038;OR=1.564,P=0.028; OR=1.018, P=0.025; OR=1.023, P=0.015, respectively). The risk of osteoporosis in women was 2.476 times higher than that in men of the same age. The corresponding risk of osteoporosis increased by1.305,1.564, 1.018 and 1.023 times as HDL, LDL, C3 and C4 increased by one unit. The areas under the ROC curve detected separately by HDL, LDL, C3 and C4 were 0.623,0.595,0.673 and 0.731 respectively, and the area under the ROC curve of the four items was 0.864. Conclusions The levels of blood lipids and complements play a great role in bone metabolism. The combined detection of blood lipid metabolism and complement can improve the diagnostic efficacy of senile osteoporosis.
