Objective:To investigate the influencing factors of surgical site infection (SSI) after abdominal surgery.Methods:The retrospective cross-sectional study was conducted. The clinical data of 567 patients undergoing abdominal surgery in 6 medical centers, including 445 cases in the Zhengzhou Central Hospital Affiliated to Zhengzhou University, 54 cases in the the First Affiliated Hospital of Zhengzhou University, 49 cases in the Shangqiu First People's Hospital, 10 cases in the Luoyang Central Hospital, 5 cases in the First Affiliated Hospital of Henan University of Science and Technology and 4 cases in the Henan Provincial People's Hospital, from June 1 to June 30, 2020 were collected. There were 284 males and 283 females, aged (51±18)years. Observation indicators: (1) incidence of SSI after surgery; (2) influencing factors of SSI. Follow-up was conducted using outpatient examination and telephone interview to detect the incidence of SSI. Patients without implant were followed up within postoperative 30 days, and patients with implant were followed up within postoperative 1 year. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measure-ment data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Univariate analysis was performed using the corresponding statistical methods. Multivariate analysis was performed using the Logistic stepwise regression model advance method. Results:(1) Incidence of SSI after surgery. All the 567 patients were followed up after surgery as planned. There were 27 cases with SSI after surgery including 9 cases with superficial incision infection, 9 cases with deep incision infection, 9 cases with organ/gap infection. Of the 27 cases with SSI after surgery, 18 cases with positive results of incisional microbial culture including 8 cases with positive results of Escherichia coli, 6 cases with positive results of Klebsiella pneumonia, 3 cases with positive results of Enterococcus faecium and 1 case with positive result of Pseudomonas aeruginosa. (2) Influencing factors of SSI. Results of univariate analysis showed that age, preoperative hemoglo-bin, preoperative albumin, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site, surgical incision type, duration of intensive cure unite, duration of post-operative hospital stay, duration of total hospital stay, operation time, hospital expense were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( χ2=40.12, Z=?4.22, ?2.21, ?4.75, χ2=7.07, 16.43, 38.06, 17.50, Z=?4.43, ?4.42, ?7.14, ?7.15, ?5.90, P<0.05) and the American Association of Anesthesiologists Classification, preoperative oral antibiotics, surgical methods and postoperative intensive care unit stay were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( P<0.05). Results of multivariate analysis showed that age, preopera-tive fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time were independent factors affecting the incidence of SSI of patients undergoing abdo-minal surgery ( odds ratio=7.69, 1.21, 0.27, 5.82, 5.19, 19.08, 0.23, 27.76, 4.97, 1.01, 95% confidence intervals as 2.04?28.95, 1.04?1.41, 0.08?0.94, 1.36?24.85, 1.10?24.43, 4.48?81.25, 0.06?0.87, 2.54?303.53, 1.12?22.14, 1.01?1.02, P<0.05). Conclusion:Age, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time are independent factors affecting the incidence of SSI of patients undergoing abdominal surgery.

Objective:To explore the relationship between anxiety, depression and various dimensions of cognitive function in patients with mild cognitive impairment (MCI) .Methods:The convenient sampling method was adopted to conduct memory screening for 727 elderly people who visited the multidisciplinary joint memory clinic of a Class Ⅲ Grade A hospital in Beijing from January to December 2019. With their consent, 247 MCI patients were investigated using Montreal Cognitive Assessment (MoCA) , Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) .Results:A total of 247 questionnaires were distributed and 233 valid questionnaires were returned. There were 67 cases (28.8%) of MCI patients with anxiety and depression, 11 cases (4.7%) with anxiety, 53 cases (22.7%) with depression and 102 cases (43.8%) without anxiety and depression. In MCI patients, anxiety was positively correlated with delayed recall ( P<0.05) , while depression was negatively correlated with language function ( P<0.05) . MCI patients with different emotional states had statistically significant differences in language function ( P<0.05) . Conclusions:MCI patients have a higher incidence of anxiety and depression, and anxiety and depression will affect different dimensions of cognitive function in MCI patients. Medical staff need to provide targeted interventions for MCI patients with different emotional characteristics.

Objective:To explore emotional intelligence and its influencing factors in patients with sudden deafness.Methods:From January 2018 to July 2019, a total of 220 patients with sudden deafness who were hospitalized and treated in the department of otolaryngology of Xi'an XD Group Hospital were selected as research objects. General Questionnaires and Wong and Law Emotional Intelligence Scale (WLEIS) were used to investigate the general condition and emotional intelligence scores of patients with sudden deafness, the influencing factors of emotional intelligence of patients were analyzed.Results:A total of 220 questionnaires were distributed, and 198 valid questionnaires were obtained. The WLEIS score of 198 patients with sudden deafness was (14.24±0.97) . Single factor analysis found that the scores of emotional intelligence of patients with different gender, age, education level, availability of medical insurance, accompanying symptoms, lesion site, degree of hearing impairment, and type of hearing impairment were different with statistical significance ( P<0.01) . Multivariate analysis found that age, education, availability of medical insurance and degree of hearing impairment were factors affecting emotional intelligence in patients with sudden deafness ( P<0.01) . Conclusions:Emotional intelligence of patients with sudden deafness needs to be improved. In clinical practice, it is necessary to strengthen the assessment and attention to emotional intelligence ofpatientswith old age, low education level, no medical insurance and severe hearing impairment and promote emotional intelligence so as to improve prognosis and quality of life of patients.

Objective To study the relationship between sdLDL-C level and CHD.Methods Two hundred and thirty-one CHD patients were divided into carotid stenosis group (n=119) and carotid stenosis-free group (n=112).The relationship between serum sdLDL-C level and risk factors for CHD were analyzed by logistic stepwise regression analysis.Results The serum sdLDL-C level was significantly higher in carotid stenosis group than in carotid stenosis-free group (P＜0.05).The elevated rate of serum sdLDL-C level was significantly higher in carotid stenosis group than in carotid stenosis-free group when 1.39 mmol/L was set as its upper limit reference cutoff value (36.3％ vs 17.0％,P＜0.05).The serum levels of TC,LDL-C,apoB,D-dimer and Fib were significantly higher while those of HDL-C were significantly lower in carotid stenosis group than in carotid stenosis-free grou (P＜0.05).The serum levels of sdLDL-C were positively related with those of TC,LDL-C,apoB,D-dimer,Fib and negatively related with those of HDL-C (P＜0.01).Logistic stepwise regression analysis showed that TC,LDL-C,apoB,D-dimer,Fib and sdLDL-C were the independent risk factors for CHD (P＜0.05).Conclusion Serum sdLDL-C level is significantly higher in CHD patients and is thus an important risk factor for CHD.

Objective To establish a mouse model of H.pylori infection, and to evaluate the chronic pathological changes in the gastric mucosa associated with H.pylori infection.Methods 34 male 5~6-week old SPF C57BL/6 mice were used in this study.The mice were intragastrically administrated with a suspension of H.pylori SS1 strain.Two weeks after infection, rapid urease test and PCR were performed to confirm the H.pylori infection.Successfully infected mice were randomly divided into 3 groups including the control group, 6-week and 12-week infected groups.Samples of gastric mucosa were taken for pathological analysis using HE and borax methylene blue staining.The contents of myeloperoxidase (MPO), superoxide dismutase (SOD), malondialdehyde (MDA) and catalase (CAT) in the gastric tissues were detected by biochemistry, and the expression levels of COX-2, iNOS, TNF-α and IL-1β were examined by RT-qPCR.Results Compared with the control group, H.pylori colonization was observed in the gastric mucosa of the 6-week and 12-week infected mice, with chronic inflammatory cell infiltration, glandular atrophy and intestinal metaplasia to varying extents.The contents of CAT and SOD were significantly decreased, while the levels of MPO and malonaldehyde MDA, and the expression levels of COX-2,iNOS,TNF-α and IL-1β were significantly increased (P<0.05 or P<0.01).Conclusions Intragastric administration with H.pylori in C57BL/6 mice can be successfully used to generate the bacterial colonization, leading to chronic inflammatory cell infiltration, enhanced oxidative stress, and up-regulated expression of proinflammatory genes in the gastric glandular tissues at 6 and 12 weeks after inoculation.However, the inflammatory changes are more extensive in the mice at 12 weeks after infection, with glandular atrophy and intestinal metaplasia.

AIM To speculate the hypoglycemic mechanism for rats with type 2 diabetes by exploring the therapeutic effects of leaf aqueous extract from Cyclocarya paliurus on liver insulin receptor (InsR) and insulin receptor substrate 2 (IRS-2).METHODS The diabetic rat model was established through intraperitoneal injection of streptozotocin and fed with high-fat diet.The moleled rats were equally assigned into the control group and leaf aqueous extract from Cyclocarya paliurus group (extract group).After the test extract was orally administrated for four weeks,body weight,urine output,food intake,water intake and fasting blood-glucose (FBG) were measured,and the levels of serum insulin,InsR and IRS-2 mRNA in liver tissue were investigated in rats.RESULTS Compared with the control group,the extract group showed a reduction in urine output,food intake,water intake,FBG and insulin levels.Meanwhile,the rats' body weights in extract group were presented a trend to increase.The gene expressions of InsR and IRS-2 in liver tissue were up-regulated.Moreover,the insulin sensitivity was improved.CONCLUSION The leaf aqueous extract from Cyclocarya paliurus can reduce FBS,improve insulin sensitivity,which may be associated with the increase of InsR and IRS-2 gene expression in liver tissue.

Background and purpose:In recent years, epigenetics research has become a new direction of cancer research. A large number of results have shown that the abnormal changes of epigenetic modifications have close connection with cancer. Genome-wide epigenetic modifications have become new markers for cancer. This study aimed to investigate the methylation of the promoter ofDBC1 gene in cervical cancer tissues of Uyghur women in Xinjiang, to explore the correlation between the gene methylation and the infection of HPV, and to evaluate whether it can be used as a tool with high sensitivity and specificity for cervical cancer screening.Methods:This study detected the infection of HPV16, 18 in 43 normal cervical tissues, 35 cervical intraepithelial neoplasia tissues and 54 cervical cancer tissues using the polymerase chain reaction (PCR) method. The methylation of the promoter ofDBC1 gene in above-mentioned tissues was detected by the methylation-specific PCR method. The expression ofDBC1 at mRNA level was measured by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) in 10 methylation-negative normal cervical tissues and 10 methylation-positive cervical cancer tissues.Results:In normal cervical tissues, CIN tissues and cervical cancer tissues, the infection ratios of HPV16 were 18.6%, 34.3% and 68.5%, respectively; the infection ratios of HPV18 were 2.3%, 8.6% and 16.7%, respectively; and the methylation ratios ofDBC1 gene were 23.3%, 40.0%, 87.0%, respectively. In 79 high-grade squamous intraepithelial lesions (CINⅡ and Ⅲ) and cervical cancer tissues, 50 of 79 were infected with HPV16/18, while 29 of 79 were negative. The methylation ratio ofDBC1 gene was 88.0% in HPV16/18 infection positive group while the methylation ratio was 55.2% in negative group (P<0.05). The expression ofDBC1 gene at mRNA level in 10 methy- lation-positive cervical cancer tissues was significantly lower than that in the 10 methylation-negative normal cervical tissues (P<0.05).Conclusion:The methylation ofDBC1 gene may become a molecular marker to detect cervical cancer of Uyghur women in Xinjiang.DBC1 gene methylation combined with HPV16/18 infection test can be used to aid diagnosis of cervical cancer.
