ABSTRACT
Objective To examine the current situation of the career plateau among anesthesiologists and analyze the impact of occupational stressors on it. Methods A questionnaire survey was conducted on the anesthesiologists. A total of 300 questionnaires were distributed and 278 questionnaires were effectively collected. Statistical analysis using SPSS 19.0 was performed to assess the status quo of career plateau among anesthesiologists. Pearson correlation analysis and stepwise regression analysis were used to analyze the influence of occupational stressors on career plateau . Results The average value of occupational stressors among anesthesiologists was (3.22±0.55), and the average value of career plateau was (3.90±0.70). Occupational interest in the occupational stressors of anesthesiologists is negatively correlated with the occupational plateau (r=-0.552, P<0.01), and career development is negatively correlated with occupational plateau (r=-0.541, P<0.01) as well. Both occupational interest and career development show a negative predictive effect on the career plateau (β=-0.359, P<0.01 andβ=-0.334, P<0.01, respectively). Conclusion Career plateau among anesthesiologists is at a medium-to-high level. Occupational interest and occupational development in occupational stressors have a negative predictive effect on occupational plateaus, so hospital managers should pay attention to them.

ABSTRACT
OBJECTIVE@#To explore the effects of novaferon on dextran sulfate sodium (DSS)-induced colitis and expression of TNF-α in mice and to evaluate the efficacy of novaferon on ulcerative colitis and the possible mechanisms.@*METHODS@#A total of 70 BALB/C mice [weight (20.0±2.0) g, 8-week years old, female, pathogen free] were randomly divided into 7 groups: a normal group, a model group, a mesalazine treatment group, a prednisone treatment group, a low-dose novaferon group, a middle-dose novaferon group and a high-dose novaferon group (10 mice per group). The normal group-mice were given distilled water. The ulcerative colitis model was established by treated the mice with 4% DSS for 7 continuous days. At the 8th day, the mice in the all of drug treatment groups were injected corresponding drugs (i.p.). During the experiment, the general situation, daily weight, stool trait and occult blood were recorded, and the mice were killed on the 14th day. The disease activity index (DAI), colon length, histological scores were assessed. Immunohistochemistry was used to measure the expression of TNF-α in colonic mucosa.@*RESULTS@#1) The mice treated with DSS solution showed diarrhea, mucous stool and bloody stool, and the DAI score increased gradually. The mesalazine, predinison and nofaferon could ameliorate the general situation of the mice, reduce the DAI and histological scores, and reverse the decrease in the colon length. 2) Compared with the model group, the DAI scores were significantly decreased in the novaferon groups (at low, middle or high dose), the mesalazine group or the prednisone group (all P0.05). The efficacy of novaferon in the middle-dose group and the high-dose group are better than that in the mesalazine group, the prednisone group and the low-dose novaferon group (all P0.05). 4) The TNF-α expression was significantly down-regulated in the novaferon groups (at low-dose, middle-dose or high-dose), the mesalazine group and the prednisone group compared with model group (all P0.05); the decrease of TNF-α expression by novaferon displayed a dose-dependent manner. Compared with the mesalazine group or the prednisone group, the TNF-α expression in novaferon groups at all dosages was dramatically reduced (all P<0.01).@*CONCLUSION@#Novaferon can improve the DAI scores and colonic tissue injury in ulcerative colitis induced by DSS in mice, and down-regulate the TNF-α expression in dose-dependent manner.

Objective To determine the effect of prokinetic agents such as domperidone, mo-sapride, clarithromycin, and itopride on the electrical activity of the stomach and duodenum in SD rats, and also to explore the mechanism. Methods The organism functional experiment system BL-420E was used to record the myoelectrical activity in the stomach and duodenum of SD rats in all groups using domperidone, mosapride, itopride, clarithromycin, and physiological saline on the inter-digestive phase. The effect of the prokinetic agents on the amplitude and freqency of gastric and duo-denal electromyologram in the SD rats was compared. The antagonists such as atropine, phento-lamine, and propranolol were added to investigate the mechanism of action with all prokinetic agents. Results All prokinetic agents increased the amplitude and frequency of gastric and duodenal fast waves in the SD rats (P<0.05). The effect of itopride was the most obvious among the 3 groups (P<0.05), and clarithromycin had the weakest effect (P<0.05). The amplitude and frequency of gastric and duodenal fast waves in the SD rats in the groups of clarithromycin, domperidone, mosa-pride, itopride, and physiological saline were inhibited by atropine (P<0.05) , but not by phento-lamine and propranolol. Conclusion Itopride, mosapride, domperidone, and clarithromycin can in-crease the amplitude and frequency of gastric and duodenal fast waves in the SD rats. The mechanism may be related to cholinergic receptors, but not adrenergic receptors.

To investigate the reliability and feasibility of human papillomavirus (HPV) DNA test in cervical scraping smears with polymerase chain reaction (PCR), 131 cases of cervical scraping specimens were collected, and the positive rates and accuracy of HPV infection were determined in normal subjects and cervical cancer patients. GP5+/GP6+ and E7 primer pairs designed for detecting HPV L1 and HPV type 16 E7 were tested in this study. Our results showed that positive rates of HPV DNA in normal population and cervical cancer patients were 32.99 % and 73.53 % respectively and there was significant difference between them (P＜0. 001). In normal subjects, detection rates of HPV DNA with GP5+/GP6+ and E7 primer pairs were 27.84 % and 16.49 % respectively, with statistically significant difference between them (P＞0.05). However the detection rates in cervical cancer patients were 38.24 % and 67.65 % for the two markers, with a significant difference found between them (P＜0.05). It is concluded that HPV DNA test with PCR for cervical scraping smears was feasible. GP5+/GP6+ primer pairs may be a useful probe to screen HPV infection in normal population, but they are not sensitive enough in cervical cancer patients. It is suggested that high risk type HPV DNA test was very useful in population with high risk of cervical cancer.
ABSTRACT
Full-length coxsackie adenovirus receptor (CAR) eukaryotic expression plasmid was transfected into an ovarian cell line, SKOV3, and its effect on the change of malignant metastasis phenotype was explored. CAR mRNA and protein expression levels among 4 ovarian cancer cell lines (A2780, SKOV3, SW626, CAOV3) and the positive control 293 (a transformed human embryo kidney cell line) was detected by using semi-quantitative RT-RCR and Western blot and compared. CAR-negative SKOV3 was transfected with the eukaryotic expression plasmid containing a full-length CAR cDNA and mock-vector respectively. The positive clones were screened by G418.The biological behavior changes of positive transfected cells were gauged by colony formation in soft agar assay and cell adhesion assay. Among the cell lines, there were obviously different CAR expression levels. CAR could not be detectedin SKOV3. In transfected cell group, CAR expression was enhanced obviously as compared with non-transfected or mock-transfected groups. Cell adhesion in the transfected group was promoted. The number of colony formation was reduced significantly in transfected groups (25.32±8.91) as compared with that in non-transfected group (88.75±13. 98) and mock-transfected group (82. 53 ±19.37). Among the 4 ovarian cancer cell lines,CAR expression level was variable. Exogenous CAR expression had a potential role in inhibiting the malignant metastasis phenotype of ovary cancer cells.

To construct eukaryotic expression vector expressing full length anti-sense pituitary tumor transforming gene (PTTG) mRNA and observe its blocking effect on the potential invasion of human ovarian carcinoma cell line SK-OV-3. PCR primers containing designed enzyme cut sites were used for cloning full-length PTTG gene fragment, and the resulting PCR product was inserted into the eukaryotic vector pcDNA3.1 in the antisense direction. The recombinant vector was then transfected into SK-OV-3 by Lipofectamine. The positive cell clone was screened by G418, PTTG and bFGF at protein level expression were detected by Western blot. The biological behavior change of transfection positive cells was observed by colony formation in soft agar assay. Our results showed that SK-OV-3 clones stably expressing full-length recombinant pcDNA3.1-PTTGas were obtained. The expressions of PTTG and bFGF protein in transfected cells were decreased by 61.5% and 52.3%, respectively as compared with non-transfected ones. The number of colony formation was reduced significantly in transfected cells as compared with empty vector transfected and non-transfected cells. It is concluded that the recombinant vector pcDNA3.1-PTTGas is a novel tool and provides an alternative anti-sense gene therapy targeted at PTTG in human carcinoma.
