This paper deals with the analysis and discussion on how to harmonize the following three relations respectively between general objective and concrete objective, pertinence and systematicness as well as political nature and actualization in ideological and political theory education and teaching in higher institutions.

Objective To understand the species,clinical distribution features and drug susceptibility situation of bloodstream infection pathogenic bacteria in this hospital to provide reference for clinical empirical treatment.Methods The retrospective analysis was performed on 1 938 strains of pathogenic bacteria isolated from blood culture in our hospital from January 2012 to August 2016,their species distribution,department distribution and drug sensitivity were analyzed.Results A total of 1 938 strain of bacteria were comprised of 56 kinds of bacteria and 8 kinds of fungi.Gram-negative bacteria had 1 216 strains,accounting for 64.2%,Gram-positive bacteria had 677 strains,accounting for 34.9%,Fungi had 45 strains,accounting for 2.4%.The top 5 of isolation rates were Escherichia coli(628 strains,32.4%),Klebsiella pneumoniae(230 strains,11.9%),Salmonella(143 strains,7.4%),Staphylococcus epidermidis(142 strains,7.3%) and Staphylococcus hominis (130 strains,6.7%).Enterobacteriaceae bacteria had 1 098 strains(58.0%),which was dominated by Escherichia coli and Klebsiella pneumoniae,in which 363 strains(57.8%) were Escherichia coli and 85 strains(37.0%) were extended spectrum β lactamases (ESBLs) producing Klebsiella pneumoniae.Nonfermenters had 118 strains(6.1%),Acinetobacter baumannii and Pseudomonas aeruginosa were predominant.Staphylococcus aureus had 75 strains (3.9%),the MRSA occurrence rate was 25.3%,coagulase-negative staphylococci (CoNS) had 401 strains (20.7%),the methicillin-resistant CoNS occurrence rate was 72.8%.Enterococcus had 85 strains(4.5%).The top 5 departments in positive rates were respiratory department,ICU,hepatobiliary department,gastroenterology department and hematology department.The other departments were consistent to the overall distribution except for ICU and pediatrics.The majority of Acinetobacter baumannii showed multi-drug resistant.Vancomycin-resistant Staphylococcus and Enterococcus did not be detected,Candida maintained good sensitivity to commonly used antifungal agents.Conclusion Bloodstream infection pathogenic bacteria in this hospital are widely distributed.Commonly used drug have different sensitivities,the overall drug resistance rate is higher,clinic may conduct early medication according to the pathogenic bacterial department distribution and drug sensitivity.

Possessing ideological qualities is a gradual process. We should establish a multiplex, synthetical and entire assessment system for the ideological and political theory course exams in medical colleges. The innovation of exam mode can promote the diversification of teaching style.

Objective To investigate the mRNA and protein expression of GPX3 gene in non-small cell lung cancer (NSCLC) patients, and then discuss the clinical significance of GPX3 in NSCLC patients. Methods Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the GPX3 mRNA and protein levels in NSCLC tissues and adjacent non-cancerous normal lung tissues from 60 patients undergoing surgical treatment. The correlation between the expression levels of GPX3 and clinicopathological features was analyzed. Results The relative expression value of GPX3 mRNA was higher in adjacent non-cancerous tissues than in non-small cell lung cancer tissue (P < 0.05). GPX3 mRNA expression was significantly correlated with TNM stage、differentiation and lymph node metastasis. The integral optical density value of GPX3 protein confirmed was lower in adjacent non-cancerous tissues than in non-small cell lung cancer tissues (P < 0.05). In additional, the expression of GPX3 was related to TNM stage and lymph node metastasis. Conclusion The expression of GPX3 gene may play an important role in the carcinogenesis and progression of NSCLC.

METHODS To divide animals into three groups: control, asthma and scoparone treatment groups. Choose the model guinea pigs of asthma sensitized with OA, and observe the changes of IgE, IL-4 and IFN-r in serum and pulmonary tissue homogenate of asthmatic guinea pigs and the effects of scoparone on them by means of chemolumi nescence, radio immunoassay, enzyme-linked immunoabsordent assay. RESULTS IgE and IL-4 in serum and pulmonary tissue homoge-nate of asthmatic guinea pigs obviously increase (P

Objective:To investigate the clinical features of direct and indirect carotid cavernous fistulas (CCFs).Methods:Patients with CCF treated in the Affiliated Hospital of Xuzhou Medical University from January 2010 to August 2020 were enrolled retrospectively. Relevant clinical data were collected, including the main clinical manifestations, neuroimaging features, and treatment methods. The clinical features of direct and indirect CCFs were compared.Results:A total of 31 patients were enrolled in the study, 29 (93.5%) had ocular symptoms, of which conjunctival hyperemia and edema ( n=24, 77.4%), exophthalmos ( n=19, 61.3%) and orbital murmur ( n=18, 58.1%) were most common. There were 23 patients (74.2%) in direct CCF group and 8 (25.8%) in indirect CCF group. The former had more history of head trauma (78.2% vs. 12.5%; P=0.002), more flow volume (high-flow CCFs: 100% vs. 37.5%; P<0.001) and more likely to cause orbital murmur (69.6% vs. 25.0%; P=0.043). Endovascular embolization was safe and effective. The common methods of endovascular embolization were EVAL glue combined with coil embolization ( n=18, 66.7%) and detachable balloon embolization alone ( n=6, 22.2%). Conclusion:Ocular manifestations are most prominent in patients with CCFs. Direct CCF is more common, usually with a history of head trauma, and the clinical and imaging features are more typical. Interventional embolization is the preferred treatment option for patients with CCF.

Objective:To investigate the relationship of papillary thyroid microcarcinoma (PTMC) with serum thyroglobulin.Methods:Data of 539 patients with papillary thyroid nodule (≤1cm) in Department of Thyroid and Breast Surgery of the Second Hospital of Anhui Medical University and the Department of Oncology Surgery of Suzhou Municipal Hospital for thyroidectomy were retrospectively analyzed. All of the nodules were classified as TI-RADS 4b with ultrasound. According to the postoperative pathological results, patients were divided into PTMC group (experiment group) and benign tumor group (control group) . The PTMC patients were also divided into lymph node metastasis group (experiment group) and no lymph node metastasis group (control group) based on the cervical lymph node metastasis. Then we analyzed the relationship between thyroid stimulating hormone (TSH) , thyroglobulin antibody (TgAb) , thyroid peroxidase antibody (TPOAb) and thyroglobulin (Tg) with PTMC and lymph node metastasis by SPSS.Results:Age, TSH, Tg and TgAb were independent risk factors for PTMC, B: -0.020, 0.192, 0.026, 0.008, 95% CI: 0.962-0.998, 1.045-1.404, 1.015-1.038, 1.003-1.014, both P<0.05. The relations between PTMC and TSH, Tg and TgAb were positive, while age was in negative correlation with PTMC. Meanwhile, age and thyroglobulin (Tg) were also independent risk factors for lymph node metastasis in PTMC patients, B: -0.025, 0.014, 95% CI: 0.957-0.994, 1.008-1.021, both P<0.05. Age was negatively correlated with lymph node metastasis and Tg was positively correlated with lymph node metastasis. Tg level higher than 26.520 ng/ml indicated that the nodule was PTMC (sensitivity: 0.560, specificity: 0.719) , and Tg level higher than 36.695 ng/ml predicted lymph node metastasis in PTMC patients (sensitivity: 0.532, specificity: 0.788) . Conclusion:Tg is a sensitive serum index for identifying PTMC from benign thyroid nodule, and it is also related to lymph node metastasis in PTMC patients.

Objective To investigate the expression of pSTAT5 in 7 pancreatic carcinoma cell lines,and the change of expression of pSTAT5 in pancreatic carcinoma cells SW1990 after growth hormone (GH) treatment, and explore its molecular mechanism. Methods Human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, AsPc, P3, PANC1) were cultured in vitro, and Western blotting was used to detect the expression of pSTAT5 in these cell lines. SW1990 in exponential growth phase was collected and nude Balb/c mice were inoculated with SW1990 cells. When tumors became palpable after inoculation, mice (normal saline group). 1 h, 2 h and 24 h after the last dose of GH treatment, the mice were sacrificed.Western blotting was used to detect the expression of pSTAT5 in SW1990 and inoculation tumor cells after GH injection. Results Positive expression of pSTAT5 was observed in all human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, Aspc, P3, PANC1). 5 minutes after GH (50 ng/ml) stimulation, the expression of pSTAT5 in SW1990 was 0.57 ±0.05, which was significantly increased; and it reached 0.64 ±0.04 at 10 minutes, then decreased to 0.39 ±0.03 at 15 minutes, however, it remained higher than that in the control group at 1 h (0.33 ± 0.02 vs 0.25 ± 0.06), and its expression at 2 h was 0.26 ± 0.03 and returned to the normal level. The expression of pSTAT5 in xenograft was not significantly changed. Conclusions GH could rapidly up-regulate the expression of pSTAT5 in SW1990 but the effect lasted for a relatively short period. GH had no significant effect on the expression of pSTAT5 in xenograft.
