Objective To understand the relationship between Demodex and bacteria infection in rosacea (brandy nose), and to find effective means for the treatment. MethodsCellophane tape was used to detect Demodex on the nasolabial grooves and the face; sebum and tissue on face was scraped and cultured to examine bacteria under microscope. The hospital_made anti_rosacea lotion was used on the affected part two times a day for 7 days. Results It was found that 193 (74^2%) of 260 cases with rosacea were infected by Demodex and 209 (80^4%) of the patients were infected by bacteria. The overall effective rate of the treatment for rosacea was 73^5%. Conclusion Bacteria infection in rosacea is an important factor inducing rosacea. The curative effect of the anti_rosacea lotion is good.

Objective To discuss the relationship between heart rate (HR), rate of perceived exertion (RPE) and oxygen consumption in therapeutic exercises for stroke patients. Methods Eighteen stroke patients a-ble to walk independently participated in the test. K4b2 Pulmonary Function Equipment was used to record their heart Rates(min-1)and specific oxygen consumption(ml·min-1·kg-1)during the following exercises:relaxed sitting,sit-to-stand transfers, leaning against a wall and elevating the hips (strength training of the gluteus maximus) , raising the unaffected leg while the affected leg is weight bearing, raising the affected leg while the unaffected leg is weight bearing, climbing up and down stairs, and walking 60 meters. RPE was surveyed after each exercise. Results The correlation between HR and oxygen consumption was moderate (r = 0.618, P≤0.001), but it was weak between RPE and oxygen consumption (r = 0.325 ,P≤0.001). Conclusion Heart rate is a better index than RPE for eval-uating exercise intensity with stroke patients able to walk independently.

To study the therapeutic effect and possible mechanism of icariin on myocardial ischemia-reperfusion injury ( MIRI) model in diabetes rats. The model of diabetic rats were induced by Streptozotocin (STZ), then the model of MIRI was established by ligating the reversible left anterior descending coronary artery for 30 min, and then reperfusing for 120 min. totally 40 male SD were randomly divided into five groups: the control group (NS), the ischemia reperfusion group (NIR), the diabetes control group (MS), the diabetic ischemia reperfusion group (MIR) and the diabetic ischemia reperfusion with icariin group (MIRI). The changes in blood glucose, body weight and living status were observed; the enzyme activity of serum CK-MB, LDH, GSH-Px and myocardium SOD and the content MDA and NO in myocardium were detected; the myocardial pathological changes were observed by HE staining; the myocardial Caspase-3, the Bcl-2, Bax protein expressions were detected by Western blot. The result showed that the diabetes model was successfully replicated; myocardial ischemia-reperfusion injury was more serious in diabetes rats; icariin can increase NO, SOD, GSH-Px, Bcl-2 protein expression, decrease MDA formation, CK-MB and LDH activities and Caspase-3 and Bcl-2 protein expressions and myocardial damage. The result suggested that icariin may play a protective role against ischemia reperfusion myocardial injury in diabetes rats by resisting oxidative stress and inhibiting cell apoptosis.

This study investigated the role of glucose in the biogenesis of high-density lipoprotein cholesterol (HDL-C). Mouse primary peritoneal macrophages were harvested and maintained in Dulbecco's modified Eagle's medium (DMEM) containing glucose of various concentrations. The cells were divided into 3 groups in terms of different glucose concentrations in the cultures: Control group (5.6 mmol/L glucose), high glucose concentration groups (16.7 mmol/L and 30 mmol/L glucose). ATP-binding cassette transporter A1 (ABCA1) mRNA expression in the macrophages was detected by semi-quantitative RT-PCR 24, 48 and 72 h after glucose treatment. The results showed that ABCA1 mRNA expression in the 16.7 mmol/L glucose group was not significantly different from that in the control group at all testing time points (P>0.05 for each). In the 30 mmol/L glucose group, macrophage ABCA1 mRNA expression was not changed significantly at 24 h (P=0.14), but was substantially decreased by 40.4% at 48 h (P=0.009) and by 48.1% at 72 h (P=0.015) as compared with that in the control group. It was concluded that ABCA1 is of vital importance for HDL-C biogenesis. High glucose may hamper HDL-C biogenesis by decreasing ABCA1 expression, which contributes to low HDL-C level in diabetes.

Objective To investigate the application of "Guidelines for performing fetal cardiac scan", issued by the International Society of Ultrasound in Obstetries and Gynecology in 2006, in prenatal screening of fetal congenital heart disease (CHD). Method Totally, 5000 singleton pregnancies presented at the Maternal-Fetal Medical Center of the Affiliated Drum Tower Hospital of Nanjing University Medical School from September 2006 to July 2007, for prenatal screening were included in this study, with the median maternal age of 28 ( range, 18～48 ) and the median gestation of 27 ( range, 18～40 ) weeks. Ultrasound screenings were performed on each fetal heart according to "Guidelines for performing fetal cardiac scan" via the four-chamber and outflow tracts & three-vessel views and fetal echocardiographies were further conducted for suspected cases. Once congenital heart disease was confirmed, amniocentesis or cordocentesis was suggested for fetal karyotyping for ongoing pregnancies and autopsy was performed when the pregnancy was terminated after formal consent. Bom babies were followed up at 2～6 months of age using echocardiography. Result The four-chamber views were successfully obtained in 97.64% (4882/5000) of all the pregnancies , among which the left ventricular and right ventricular outflow tracts and three-vessel views were obtained in 87.69% ( 4281/4882 ), 82.51% ( 4028/4882 ) and 96.29% ( 4701/4882 ), respectively. Higher successful rate was found in the second trimester than the third trimester in obtaining the standard views (P<0.05). Finally, 73 (1.50%) among the 4882 cases were diagnosed as CHD. Fifty of them were diagnosed prenatally (24 cases in the second trimester and 26 cases in the third trimester) and 23 were missed and 1 misdiagnosed by prenatal ultrasound. Eighteen cases were found with extracardiac malformations. Autopsy was performed in 19 CHD which diagnosed prenatally, and all autopsy reports were consistent with ultrasound foundings. Twelve babies received postnatal echocardiography among which 11 were unanimous, and 1 baby diagnosed as tricuspid insufficiency prenatally was confirmed normal after birth. Abnormal karyotype was found in 7 out of the 23 who had karyotyping performed. Altogether, 28 cases were diagnosed by four chamber view only and 50 cases by combining other views, giving the sensitivity, specificity, false negative rate and false positive rate of 69% (50/73), 99.98% (4808/4809), 0.48% (23/4831) and 2% ( 1/51 ) ,respectively. Conclusion The "Guidelines for performing fetal cardiac scan" is practical and easy to abide by. The optimal time for fetal cardiac examination is at 18～27 weeks of gestation. Four-chamber view together with the outflow tracts and three-vessel views examination can detect 69% of CHD in utero.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To investigate whether early goal-directed therapy ( EGDT ) could lower the mortality rate in patients with severe sepsis and septic shock. Methods Articles with items sepsis, severe sepsis, septic shock, EGDT were retrieved from MEDLINE, EMBASE, Cochrane, Wanfang Data and CNKI. Inclusion criteria included randomized controlled trial, subjects concerning patients with severe sepsis or septic shock, endpoints with short-term mortality [ in-hospital, intensive care unit ( ICU ) or 28-day ] and long-term mortality ( 60-day or 90-day ). Related risk ( RR ) and 95% confidence interval ( 95%CI ) were used as indices to judge the difference in mortality rate between EGDT group and standard treatment group. RevMan 5.2 software was used for Meta analysis. Results There were 8 studies meeting inclusive criteria with a total of 4 853 patients. For patients with severe sepsis and septic shock, compared with the group with routine treatment, EGDT showed a decrease in the short-term mortality ( RR = 0.74, 95%CI=0.66-0.82, P<0.000 01 ), but did not decrease the long-term mortality ( RR=0.99, 95%CI=0.92-1.06, P=0.81 ). Conclusion EGDT strategy may decrease the short-term mortality in patients with severe sepsis and septic shock, but it showed no influence on the long-term mortality.

Objectives To assess the performance of first trimester ultrasound screening for fetal structural and chromosomal anomalies based on a detailed anomaly and nuchal translucency (NT) scan at 11-13+6 weeks' gestation.Methods A prospective cohort study was conducted at Nanjing Drum Tower Hospital.Fetuses with a crown-rump length (CRL) between 45 mm and 84 mm scanned during December 2015 to March 2016 were enrolled in this study.After a detailed first-trimester anomaly scan followed the protocol of systematic standardized scan plans,fetuses with congenital abnormalities were screened out.Second trimester ultrasound screening and postnatal examination were performed for further examination of fetal anomalies.Cytogenetic analysis was performed on the fetuses with informed consent.Results (1) A total of 1 154 fetuses were enrolled in this study and among them,36 (3.1％) cases of fetal abnormalities were diagnosed through prenatal examination (35 cases) and postnatal examination (one case).(2) Twenty-one (58.3％) out of the 36 cases with structural and chromosomal anomalies were screened out by using the first-trimester scan,including eight cases of congenital cardiac defect (two cases of atrioventricular septal defect,one case of tricuspid atresia,one case of tetralogy of tetralogy,one case of right ventricle aneurysms and one cases of hypoplastic left heart syndrome combined with cystic hygroma with one case combined with polydactyly),four cases of central nervous system anomaly (three cases of exencephaly and one case of anencephaly combined with double outlet right ventricle),two cases of cleft palate/lip with one case combined with double outlet right ventricle,two cases of exomphalos,one case of amniotic band syndrome,one case of spinal bifida combined with megacystis,one case of umbilical cyst,one case of polydactyly and one case of cystic hygroma.One case of twin pregnancy chose selective fetocide to the fetus with exencephaly and 16 cases terminated pregnancy.The other four cases were confirmed by second trimester ultrasound screening and postnatal examination.Fourteen (38.9％,14/36) new cases of structural and chromosomal anomalies were detected by the second-trimester scan,six of which terminated the pregnancies and the rest were confirmed at term.One (2.8％,1/36) case of polydactyly was detected postnatally.(3) Chromosomal microarray analysis was performed on 28 cases,seven of which were identified as having chromosomal abnormalities including five cases detected in the first trimester and two cases detected in the second trimester.(4) Out of the 20 fetuses with abnormal NT in early trimester,which accounted for 1.7％ of all enrolled fetuses,nine were indentified with major structural or chromosomal abnormalies,a quarter of all abnormal fetus.Conclusions Detailed anomaly scan and NT scan in the first-trimester can increase the detection rate of fetal structural and chromosomal anomalies as compared with the traditional NT scan and provide earlier detection of severe fetal abnormalities as compared with second trimester anomaly scan.

Objective To investigate the clinical characteristics of senile male patients with acute coronary syndrome (ACS)．Methods 56 ACS inpatients,who hospitalized from April 2006 to April 2008 in the Coronary Care Unit of South Building,and 48 male inpatients with stable angina pectoris (SAP)，who hospitalized at the same period in the Department of Cardiovascular Disease,were the objects．Their general data,perticipating factors and characteristics of symptomes were compared and analyzed．Results Compared to the SAP group,the ACS group demonstrated to have markedly more cases with diabetes,more cases with old myocardial infarction,more cases elicitated by non-specific percipitating factors,and more cases presenting untypical angina．The differences had statistical meaning (P<0.05).Conclusions It is important to control multiple risk factors of senile ACS patients．Furthermore,it is vital to recognize the early symptomes of untypical ACS so that we can prevent it from occuring and/or aggravation．ACS patients,especially those with diabetes and old myocardial infarction,should be paid with more attention,educated with the prevention stratigies and receive the early screening examination.We should further expand the depth and breadth of health education about prevention stratigies and provide patients with fine individualized health education.
