Objective] To study Professor Wang Xinghua's experience in the treatment of cough. [Methods] Typical cases of cough treated by Wang Xinghua are selected for the analysis of causes, pathogenesis, treatment methods and detailed prescription. [Results] Six exogenous climatic evils, internal injury caused by excess of seven emotions, improper diet and overwork all can damage lung Qi, inducing cough. Delayed or improper treatment can lead to sub-acute types of cough, while weak constitution and deficiency of vital Qi consumed by prolonged diseases result in chronic cough. External induced acute cough mainly is excess type, while internal damage induced chronic cough is more prone to have deficient type. Syndrome differentiation based on external and internal factors, cold and heat, deficiency and excess is recommended for the treatment of cough. Those frequently used methods include dissipating wind-cold, expelling wind-heat, clearing away phlegm-heat, reinforcing earth to generate metal, removing dampness to reduce phlegm, warming Yang for resolving fluid retention, nourishing Yin to moisten dryness. Exogenic cough should be treated with expelling pathogens, assisted with tonifying vital Qi. Chronic cough resulting from disordered visceral function should be treated with tonification and conditioning, combined with expelling pathogen. [Conclusion] Professor Wang Xinghua's experience for treating cough is worth spreading for the comprehensive understanding of the pathogenesis of the disease, accurate syndrome differentiation, unique medicine application and significant treating effect.

Objective To observe the efficacy and safety of vildagliptin combined with acarbose in treating type 2 diabetes. Methods 78 patients with type 2 diabetes were divided into two groups to have additional vildagliptin combined with acarbose or acarbose combined with placebo. The clinical efficacy and adverse reactions after 12 weeks were investigated. Results In the treatment group, FBG, 2 h PG and HbA1C declined after treatment (P < 0.05) and FCP, 2 h CP, FINS and 2 h INS increased (P < 0.05). Compared with the control group, FBG and HbA1c in the treatment group were reduced and owever, FCP, 2 h CP, FINS and 2 h INS were increased more significantly (P < 0.05). There was no difference in the incidence of overall BMI between the two groups (P > 0.05). There were either liver and kidney damage (P > 0.05), nor hypoglycemia. Conclusion Vildagliptin combined with acarbose is superior to Acarbose combined with placebo , and it produced no more untoward effect.

Objective:To investigate the current situation of students' academic procrastination behavior in medical colleges and universities and its influencing factors, and to put forward suggestions to reduce the academic procrastination of medical students.Methods:A total of 1 327 undergraduate students from three medical colleges and universities in Heilongjiang Province were randomly selected to receive questionnaire investigation on life satisfaction, anxiety, and academic procrastination. SPSS 23.0 was used for data analysis.Results:①The total procrastination scores of medical students were (35.00±8.92) points. ②There were statistical differences in the academic procrastination of medical students with different genders, whether the only children, the reasons for choosing the major, and the level of achievement ( P < 0.05). There was no statistical difference in academic procrastination among medical students of different ages and grades ( P > 0.05). ③Medical students' procrastination was positively correlated with their anxiety level ( r = 0.102, P < 0.01), and negatively correlated with life satisfaction ( r = -0.117, P < 0.01). ④Regression analysis showed that the following six predictive variables including the level of achievement, gender, life satisfaction, anxiety, reasons for choosing the major, and whether the only children could effectively explain the variance of 14.2% academic procrastination of medical students. Conclusion:The overall degree of academic procrastination of medical students is higher than that of non-medical students. And the students' achievement level, gender, life satisfaction, anxiety, the reasons for choosing this major and whether the only child are the influencing factors of academic procrastination.

AIM: To explore the expression and significance of receptor tyrosine kinase anexelekto (Axl) in nasopharyngeal carcinoma (NPC).METHODS: Immunohistochemistry was used to detect the Axl protein expression of 78 patients with NPC and 32 patients with nasopharyngeal chronic inflammation (NPI).The correlations between the Axl protein levels and the clinical parameters of NPC patients were analyzed.NPC cells were cultured in vitro, and the expression of Axl in well differentiated CNE1 cells, poorly-differentiated CNE2Z cells and undifferentiated C666-1 cells was detected by immunofluorescence staining.After treatment of the CNE1and C666-1 cells with Axl specific inhibitor TP-0903, CCK-8 assay was used to detect cell viability, flow cytometry was adopted to analyze the cell cycle distribution, qPCR was used to examine the mRNA levels of Axl and proliferating cell nuclear antigen (PCNA), and Western blot was used to examine the protein expression of Axl and p-Axl.RESULTS: Axl protein was localized in the cell membrane and cytoplasm.The rate of high expression of Axl in NPC was significantly higher than that in NPI (P<0.01).High Axl expression showed no correlations with NPC patients'' age, gender and M stage, while positively correlated with the clinical stage, T stage and N stage (P<0.05).Axl protein showed a low level in the CNE1 cells, but showed a high level in CNE2Z and C666-1 cells.TP-0903 inhibited cell viability in concentration and time dependent manners.TP-0903 at 2 nmol/L showed significant inhibitory effects, as evidenced by arresting the cell cycle at G0 phase and reducing Axl activity and PCNA expression.CONCLUSION: High expression of Axl promotes the clinical progress of NPC.TP-0903 significantly inhibits the viability of NPC cells, suggesting that Axl may be a valuable target in the NPC treatment.

Objective:To investigate the current situation and analyze the influencing factors of job satisfaction of infectious disease physicians in Jiangsu Province.Methods:From April to May 2021, a stratified random sampling method was used to select 10 municipal level infectious disease hospitals in Jiangsu province. An electronic questionnaire survey was conducted on the infectious disease physicians of these hospitals using an online questionnaire platform. The questionnaire mainly included the job satisfaction scale developed by Greenhaus and Wormley, and a self-designed job satisfaction influencing factor scale based on resource conservation theory. At the same time, semi-structured interviews were made with relevant insiders on such issues as salary and benefits, and career development among others. Descriptive analysis was conducted on the questionnaire data, while single factor analysis and multiple linear regression analysis were used to identify the factors that affect their job satisfaction, and the results of the interviews were studied with Colaizzi 7-step analysis.Results:A total of 457 valid questionnaires were recovered. The job satisfaction score of infectious disease physicians was (3.38±0.76). The results of univariate analysis showed significant differences in job satisfaction scores among infectious disease physicians of different ages, educational backgrounds, professional titles, and positions. The results of multiple linear regression analysis showed that salary and benefits ( B=0.141, P<0.001), work environment ( B=0.128, P<0.001), leadership support ( B=0.112, P=0.014), development security ( B=0.117, P<0.001), self-efficacy ( B=0.084, P=0.045) and social support ( B=0.285, P<0.001) were both influencing factors of their job satisfaction. The interview results identified such problems as low salary, insufficient salary security, large gap in social security levels between in-staff and off-staff physicians, and insufficient career development potential. Conclusions:The job satisfaction of infectious disease physicians in Jiangsu Province was found at an average level. It is recommended that the government increase the investment in personnel expenses for infectious disease physicians, optimize the salary and benefits structure, pay attention to the career development needs of middle-aged and young physicians, and care about the social relationship needs of infectious disease physicians to improve their job satisfaction.

Objective To explore the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists in Heilongjiang Province.Methods Questionnaire survey was used for data collection.Descriptive statistics,Pearson correlation analysis and multivariate linear hierarchy regression analysis were performed to analyze the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists.Results The average value of work-family conflict among anesthesiologists was (2.99 ± 0.57).The finding indicated that work-family conflict of anesthesiologists had a significant negative effect on job satisfaction (β=-0.248,P＜0.01) and a positive effect on turnover intention (β=0.329,P＜0.01).Conclusion Anesthesiologists' work-family conflict is above the middle level in Heilongjiang Province.The work-family conflict of anesthesiologists can reduce job satisfaction and increase turnover intention.

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.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.
