Objective To investigate the influence of bloody cervical cell samples on human papillomavirus(HPV) genotyping detection using flowcytometry fluorescence hybridization kit.Methods According to the concentration of hemoglobin(Hb),cervical cell samples were divided into five groups,including group A with Hb of 0 g/L(10 cases),group B with 0 g/L100 g/L.In each group,50% samples were with initial positive results of HPV genotyping detection.Every sample was detected using sample volume of 50,100,200,500 and 1 000 μL different volumes for testing and analysis results.Results For all samples with initial negative results,five samples with initial positive results in group A and five samples with initial positive results,the detected results of different sample volume were without differences.In the 10 samples,with initial positive results of group C,D and E,there were four,four and nine samples respectively,were with false negative detected results of different sample volumes.Conclusion Bloody cervical cell samples could cause false negative results of HPV genotyping detection using flowcytometry fluorescence hybridization kit.It might be necessary to set optimal sample volume according to the concentration of Hb for ensuring the accuracy of genotyping detection.

Objective To investigate the effects of α7 nicotinic acetylcholine receptor (α7nAChR) on CD11b, IL-1β, IL-18 and TNF-α in acute respiratory distress syndrome (ARDS) mice. Methods A total of 40 healthy and clean male Balb/C mice (6 weeks old) were randomly divided into normal group (N group), normal saline control group (NS group), ARDS group (A group), and ARDS mice treated with nicotinic acetylcholine receptor agonist after bilateral cervical vagotomy group (J group), with 10 mice in each group. The right lung structure of mice in each group was observed by hematoxylin-eosin (HE) staining, the lung tissue wet weight/body weight ratio (LWW/DW ratio) was detected, and the percentage of CD11b in the alveolar lavage fluid of mice was detected by flow cytometry. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of IL-1β mRNA, IL-18 mRNA and TNF-α mRNA in left lung tissue. Serum IL-18 was determined by enzyme-linked immunosorbent assay (ELISA) and double antibody sandwich method. Results HE staining of the right lung of mice in group N and NS showed normal structure, while the lung interstitial of mice in group A showed a large number of inflammatory cells infiltrated, alveolar wall thickened, alveolar structure destroyed and alveolar cavity fused. The alveolar structure of mice in group J was intact, with a little damage and alveolar cavity. The percentage of CD11b in alveolar lavage fluid in group A was higher than that in the other three groups, and the difference was statistically significant compared with group N, NS and J, respectively (P<0.05). The expressions of IL-1β mRNA, IL-18 mRNA and TNF-α mRNA in the left lung of mice in group J were statistically significant compared with those in group N, NS and A (P<0.05), and the serum IL-18 level of mice in group A was higher than that in the other three groups, and the differences were statistically significant compared with groups N, NS and J, respectively (P<0.05). Conclusions Activation of α7nAChR can directly inhibit the release of CD11b in lung tissue and reduce the accumulation of inflammatory factors. Simultaneously, it can also directly inhibit the expression of IL-β1 mRNA, IL-18 mRNA and TNF-α mRNA in lung tissue and the release of IL-18, thus inhibiting the inflammatory response of ARDS and alleviating the pathological changes of ARDS.

Objective To investigate the effects of telmisartan on the expression of angiotensin converting enzyme2 (ACE2) mRNA in monocyte-derived macrophages of hypertensive patients companied with diabetes.Methods 62 essential hypertensive patients companied with diabetes were randomly divided into two groups:regular treatment group,and telmisartan group.Then the content of ACE and ACE2 in serum was detected by ELISA,and the expression of ACE mRNA and ACE2 mRNA in monocyte-derived macrophages of patients was detected by RT-PCR before and after having been treated.Results (1) After having been treated for 4 weeks and 12 weeks,the blood pressure of the patients in two groups were decreased significantly,Comparing with regular group,telmisartan group seemed to have more obvious therapeutic effect (P ＜ 0.05) ; (2) After having been treated for 12 weeks,glycosylated hemoglobin diseased in both group,but there was no significant difference between the two group (P ＞ 0.05) ; (3) In telmisartan group,the content of ACE2 in serum was increased after having been treated for 12 weeks than that in regular treatment group,[(23.9 ± 8.2) U/L vs (16.3 ± 8.9) U/L,P ＜ 0.05] ; and the expression of ACE2 mRNA in monocyte-derived macrophages in telmisartan group was obviously increased after 12 weeks comparing with regular treatment group (0.73 ±0.06 vs 0.51 ±0.04,P ＜0.01).Conclusion The role of telmisartan in decreasing blood pressure and it's advantage to the metabolism of glucose are partly related with the up-regulation of ACE2 mRNA.

Objective To investigate the value of high-sensitivity C-reactive protein (hs-CRP) combined with high-sensitivity cardiac troponin T (hs-cTnT) for prognosis of patients with acute coronary syndrome (ACS).Methods One hundred and eighteen patients with ACS were selected from July 2011 to December 2012.According to the clinical feature,they were divided into unstable angina pectoris (UAP) group (38 cases),non ST segment elevation myocardial infarction (NSTEMI) group (38 cases) and ST segment elevation myocardial infarction (STEMI) group(42 cases).They were followed up for 3 months,and the incidence of cardiovascular events and cardiac death was observed.Twenty healthy people were selected as control group.Results The serum level of hs-CRP on admission in UAP group,STEMI group,NSTEMI group was higher than that in control group,and NSTEMI group was highest.And there was significant difference between NSTEMI group and STEMI group,and also between NSTEMI group and control group (P ＜ 0.05).The serum level of hs-cTnI was increased in STEMI group and NSTEMI group.The increased degree in STEMI group was higher than that in NSTEMI group,and there was significant difference (P ＜0.05).The incidence of cardiovascular events and cardiac death within 3 months after discharge in patients with the serum level of hs-CRP ≥ 3 mg/L on admission in UAP group and NSTEMI group,STEMI group was 6/11,40.0％ (12/30),46.4％ (13/28),which was higher than that in patients with the serum level of hs-CRP ＜ 3 mg/L[11.1％(3/27),3/8,5/14],and there was significant difference(P＜ 0.05).The incidence of cardiovascular events and cardiac death within 3 months after discharge in patients with the serum level of hs-cTnT≥ 1.0 μ g/L on admission in NSTEMI group and STEMI group was 16.7％(5/30) and 18.4％(7/38),which was higher than that in patients with the serum level of hs-cTnT ＜ 1.0 μ g/L (1/8,1/4),and there was significant difference (P ＜ 0.05).Conclusion Significantly increased hs-CRP is an important predictor of poor prognosis of ACS patients.hs-CRP combined with hs-cTnT is helpful in early identification of high-risk patients.Giving intensive treatment to these patients in time and monitoring closely after discharge can reduce the happening of cardiovascular events.

Objective To explore the diagnostic value of whole?body bone scan combined with SPECT/CT imaging for osteofibrous dysplasia( OFD) . Methods A total of 30 patients ( 14 males, 16 fe?males, age range 10-48 ( average age 29.2) years) with OFD confirmed by pathology from June 2007 to De?cember 2014 were included. The images of whole?body bone scan and SPECT/CT imaging were retrospec?tively analyzed. Results Nineteen patients (63.3%, 19/30) showed monostotic OFD, which mainly in?volved extremities (n=18), especially the femur. Eleven patients(36.7%, 11/30) showed polyostotic OFD, which frequently be seen unilaterally (n=7). Highly or obviously abnormal uptakes of radiotracer were shown in most lesions (95.3%, 81/85) on whole?body bone planar images, the ribs and extremities showed abnormal uptake along the backbone orientation, while the cranium, pelvis and spine showed irregu?lar bulky uptake of radioactivity. On SPECT/CT images, the lesions of high or obvious abnormal uptake of radiotracer mainly showed cystic expansion growth, ground glass, vegetable sponge and mixed appearance;and the higher the radioactive aggregation degree was, the more the morphological changes were. The density and morphological changes on CT were not obvious for lesions with moderately and mildly abnormal uptake of radiotracer. Conclusion The whole?body bone scan combined with SPECT/CT imaging is an effective diag?nostic method for OFD.

Objective: To analyze the influencing factors for the 20-69-year-old residents in Anhui Province with substandard physiques, so as to provide a basis for improving the physiques of population. Methods : The 2014 physical fitness survey data of residents aged 20-69 years in Anhui Province were collected, including demographic information, physical exercise status and physical indicators ( height, weight, vital capacity, blood pressure and so on ). The physiques of residents was rated according to the "National Fitness Standards" ( 2003 edition ) . The multivariate logistic regression model was used to analyze the influencing factors for substandard physiques in different age groups. Results: Among 39 803 residents recruited, 5 081 were rated as substandard physiques and the rate was 12.77%. The rates of substandard physiques in the residents aged 20-<40, 40-<60 and 60-69 years were 11.08%, 13.11% and 16.74%, respectively. The results of multivariate logistic regression analysis showed that age, gender, household registration, education level, occupation and time spent each exercise were the influencing factors for substandard physiques among the residents aged 20-<40 years ( P<0.05 ); age, household registration, education level, occupation and physical exercise were the influencing factors for substandard physiques among the residents aged 40-<60 years ( P<0.05 ); age, gender, education level, occupation, physical exercise and time spent each exercise were the influencing factors for substandard physiques among the residents aged 60-69 years ( P<0.05 ). Conclusions The residents aged 20-69 years in Anhui Province have higher rate of substandard physiques in the 2014 survey. Age, education level, occupation and physical exercise may affect physical fitness and vary in different age groups, thus interventions should be carried out according to age.
