OBJECTIVETo explore the relation of body mass index (BMI) and waist circumference (WC) of the aged with clustering of other cardiovascular risk factors.

METHODSTotal 654 old people were checked up, and the systolic blood press (SBP), diastolic blood press (DBP), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and fasting plasma glucose (FPG) of them were investigated according to different BMI and WC, then the other cardiovascular risk factors analysis was carried out on the detection rates of SBP, DBP, TC, HDL-C, FPG level and high blood pressure, high TC, high TG. The clustering of the other cardiovascular risk factors was analyzed.

RESULTSThe rising of BMI and WC was regular cardiovascular risk factor in the aged. The average level of SBP, DBP, TC, TG, and FPG of the aged was obviously rising along with BMI and WC increasing, meanwhile the HDL-C was obviously decreased, and the detection rates of high blood pressure, high TC, TG and diabetes mellitus were obviously increased. When the BMI was 24 kg/m(2)-27.9 kg/m2, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 59.74%, 3.89%, 28.57%, 10.06% respectively, and their risks of suffering high blood pressure, high TC and TG were 1.65, 1.88, 1.85 times of those with normal BMI. When the BMI > or = 28.0 kg/m2, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 83.05%, 5.08%, 35.59%, 15.25% respectively, and their risks of suffering high blood pressure, high TC and TG were 5.44, 2.60, 2.98 times of those with normal BMI. When the man WC > or = 85 cm or women WC > or = 80 cm, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 66.15.%, 4.47%, 29.57%, 10.12%, and their risks of suffering high blood pressure, high TC and TG were 3.52, 6.51, 1.68 times of those with normal BMI. The rate of the aged with several cardiovascular risk factors was significantly increased for those with BMI > or = 24.0 kg/m2 or man WC > or = 85 cm or women WC > or = 80 cm.

CONCLUSIONThe rising of BMI and WC should be important factor for the clustering of cardiovascular risk factors in the aged.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

Based on the Bacillus sp., isolated from Lop Nur Desert, the technology of separation and purification and the antioxidant effect were studied. After centrifugation and vacuum filtration, the deproteinization of supernatant was operated with Sevag reagent. The crude exopolysaccharide (EPS) was obtained by precipitation with ethanol. The optimum conditions for the isolation were as follow: pH 7.0, temperature 4?C, time 1.5 h, and material to ethanol ratio 1: 4. Dissolved in water, the crude EPS was fractional separated on activated carbon column (1.5 cm ? 24 cm), eluted with distilled water, 60% ethanol, 95% ethanol, and the main fraction was collected. Then the EPS was purified on Sephadex G-100 gel column, eluted with NaCl (0.2 mol/L). Fractions (4 mL, each) were also combined according to total sugar by phenol-sulfuric acid method and protein content was determined by Coomassie brilliant blue. The results showed that EPS was relatively homogeneous glycoprotein. The data of antioxidation in vitro showed that the EPS had a high antioxidant activity, which could quench hydroxyl radical, superoxide radical and had antilipid peroxidation activity. All of these indicated that EPS was a good natural antioxidant.

Objective To investigate the epidemiological characteristics of Brucella aggregation of disease outbreaks, and explore the causes and possible routes of transmission in Tongxiang City for proposing prevention and control measures.Methods A case investigation was done to the first case of bovine brucellosis, while search of new case was carried out in the population.Epidemiological survey was carried out in accordance with the case study form from Chinese Center for Disease Control and Prevention that developed the unified form, at the same time, survey of risk factors were carried out.According to the principle of informed consent, blood samples were collected, brucellosis rose bengal plate agglutination test (RBPT) and tube agglutination test (SAT) were used, and positive specimens were identified by Brucella culture.Brucellosis diagnosis was based on Brucellosis Diagnostic Criteria (WS 269-2007).Results The first case was a male Fifty-six years old wine salesman from the farmers market.Serum of the patient was (+) in RBPT test, and 1 : 400 (++) in SAT test.Cattle Brucella was check out by blood culture.Totally 66 human serum samples from the case search in key groups were tested, three people were detected seropositive but Brucella culture result was negative.Three cases were determined latent infection who had contacted beef sales staff.Conclusions The survey has shown that it is possible to get infected through contact with respiratory, skin, mucous membranes of Brucella infected beef or contaminated environment.Epidemic form should be concerned of non-professional personnel who are infected with different isoforms of brucellosis.The training of clinicians should be strengthened to improve their diagnosis and treatment technology.Health education should also be carried out to raise awareness of key population of disease prevention.

This research explored the synergistic effects and the potential mechanisms of RCE-4 and various nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of cervical cancer Ca Ski cells. The MTT assay and CalcuSyn V2.0 software were used to detect cell proliferation and calculate the combination index (CI); the expression levels of various proteins were analyzed using Western blot assay; mitochondrial membrane potential (MMP) was assessed using JC-1 staining; acridine orange/ethidium bromide (AO/EB) double-fluorescence staining was used to detect the apoptosis of Ca Ski cells; a co-immunoprecipitation (Co-IP) assay was used to analyze the relative content of Bcl-2-Beclin 1 complex in Ca Ski cells. The results demonstrate that the combination of RCE-4 and NSAIDs increases the inhibition of Ca Ski cells compared to the single-RCE-4 group, and celecoxib provided the best synergistic effect among the four NSAIDs tested, with a CI of 0.32. The combination of RCE-4 and celecoxib significantly down-regulated the expression of cyclooxygenase-2 (COX-2) and nuclear transcription factor-κB (NF-κB), and promoted the expression of non-steroidal anti-inflammatory drugs activity gene-1 (NAG-1). In addition, autophagy induced by RCE-4 was markedly inhibited in combination with celecoxib, which was associated with down-regulation of the expression of microtubule-associated protein 3 (LC3)-II, Beclin 1, p62 and autophagy-related gene (ATG) 3/4B/5/7/14. RCE-4-induced apoptosis was significantly enhanced by altering the depolarization of mitochondrial membrane potential and the expression of B cell lymphoma-2 (Bcl-2), B cell lymphoma-xl (Bcl-xl), Bcl-2 associated X protein (Bax), Bcl-2/Bcl-xl-associated death promoter (Bad) and cleaved cysteinyl aspartate specific proteinase (cleaved-caspase) 3/7/9. Furthermore, the formation of the Bcl-2-Beclin 1 complex was significantly inhibited in Ca Ski cells treated with RCE-4 in combination with celecoxib. Taken together, this research shows that the combination of RCE-4 and celecoxib has a significant synergistic effect on the proliferation of Ca Ski cells by promoting apoptosis, inhibiting autophagy and disturbing the formation of the Bcl-2-Beclin 1 complex, which may be a novel strategy to increase the sensitivity of anti-cervical cancer drugs.

Objective To evaluate the outcome of the comprehensive evidence-based nursing course on Postgraduate training courses students. Methods Postgraduate training courses students in school of nursing of Fudan University were conveniently assigned to experimental group ( n =22) and control group ( n = 26). The students in the experimental group received 36 hours evidence-based nursing education. The teaching and learning outcome were evaluated by self-designed questionnaires. Results After 36 hours teaching and learning, Students in experimental group got significantly higher score on evidence-based nursing knowledge and literature criticism than control group(Z =3. 582,P<0. 01; t =3. 674,P<0. 01) ; There was no statistical difference on evidence-based nursing attitude score of students in experimental group and control group after evidence-based nursing course(t = 0. 310,P >0. 05); The results of course feedback questionnaire suggested that most of the students in experimental group were satisfied with course content, teaching materials and teaching methods. Interview results showed that students can develop system evaluation and practice Evidence-based nursing. In addition, they proposed constructive suggestions on credit hours and teaching arrangement for further implementing of evidence-based nursing course. Conclusions The knowledge and skill of EBN could be significantly improved by learning a comprehensive evidence-based nursing course for nurses studied in postgraduate nursing Program. Further study is needed to explore the effect of EBN course on students' attitude to evidence-based nursing.

Objective To explore the experience of developing evidence-based nursing (EBN) course in postgraduate nursing program in order to improve the quality of course.Methods A comprehensive project on developing EBN course for postgraduate nursing students was initiated in School of Nursing Fudan University.59 postgraduate nursing students in school of nursing, Fudan University were conveniently classified into EBN teaching group (n = 33) and control group (n = 26).The students in the EBN teaching group received 54 credit hours evidence-based nursing education.The teaching and learning experience were reflected through faculty interview and student interview. The teaching and learning outcome were evaluated by self-designed questionnaires.Results Students considered EBN course as a challenge.They experienced both positive and negative feelings during learning EBN.The critical appraisal, data extraction, Meta analysis and evidences utilization were seen as bigger challenges. However, they valued the experience of learning EBN as the opportunity for them to integrate knowledge and skill of literature searching, clinical epidemiology, health statistics, and nursing research into the learning of EBN course. Students in EBN teaching group had significantly higher score on evidence-based nursing knowledge than control group (z = 3.582, P < 0.01).Students in EBN teaching group had significantly higher scores on critical appraisal at post-course than at pre-course(t = 3.674,P < 0.01).Most of the students in EBN teaching group were satisfied with course content, teaching materials and teaching methods.In addition, they proposed constructive suggestions on credit hours and teaching arrangement for further implementing of evidence-based nursing course.Conclusions It is suggested that EBN can be developed as a course in postgraduate nursing program.The knowledge and skills on critical appraisal of literature and conducting systematic review can be improved by learning a comprehensive EBN course.However,the course content and teaching methods need further explore.

OBJECTIVETo evaluate the value of magnetic resonance imaging (MRI) in displaying the parotid gland segments of the facial nerve.

METHODSSixteen volunteers (9 males and 7 females) and 132 surgically confirmed patients with parotid tumors locating in the deep or shallow lobe of the parotid gland (including 89 with benign and 43 with malignant tumors) underwent MRI using T1WI and T2WI. The transverse images were obtained with the plane tilted 35 degrees to the foot, and the coronal images were acquired using conventional scanning.

RESULTSOn transverse T1WI, the parotid gland segments of the facial nerve displayed low signal with arc-shaped curve in the cross-section, showing a symmetrical dot-like low signal in the coronal plane. The facial nerve in 63% of the patients with parotid tumors in the cross-section could be displayed, but in the coronal plane the proportion reached 83%. MRI could accurately reveal the position of the parotid tumors in the deep or shallow lobe of the parotid gland.

CONCLUSIONMRI can show the major portion of the parotid gland segments of the facial nerve and has important value in locating the parotid tumors and displaying the relationship between the tumor and facial nerve.

OBJECTIVETo investigate the value of middle cerebral artery (MCA) and umbilical artery (UA) resistance index in predicting fetal hypoxia in fetuses with umbilical cord around the neck in late pregnancy.

METHODSEighty normal fetuses between 38 and 40 weeks of gestation and 88 fetuses with umbilical cord around neck were measured for MCA and UA pulsatility index (PI), resistance index (RI) and the peak-systolic/diastolic ratio (S/D) by means of color Doppler ultrasonography, and the resistance index ratio was calculated. Fetuses with umbilical cord around neck were estimated according to the measured normograms for the presence of fetal hypoxia, and the results were evaluated by diagnostic test.

RESULTSSignificant differences were found in MCA and UA resistance index ratio between the groups (P<0.01). There was no significant difference in the resistance index ratio between the normal group and around the neck (one round) group (P>0.05), but significant difference was found between normal group and around the neck (two rounds and more) group (P<0.01), and between the two arounds and one round groups (P<0.05). The sensitivity and specificity of MCA and UA resistance index and resistance index ratio in predicting fetal hypoxia of fetuses with umbilical cord around neck was 43%, 85%, 92%, 83%, 89%, and 100%, respectively.

CONCLUSIONMCA and UA resistance index ratio is a better indicator than its resistance index in predicting fetal hypoxia of fetuses with umbilical cord around neck, and may help in early detection of fetal hypoxia for a diagnosis before fetal distress.
