In recent years, improving teacher's professional ethics is an essential topic that has repeatedly appeared in the national teacher's policies. Researchers have also tried to update the paradigm and orientation of teacher ethics research through new terms. However, current research mainly focuses on exploring teacher's professional ethics from an individual perspective, while relatively neglecting the understanding of teacher's professional ethics phenomena from a group perspective and analyzing their social characteristics. Indeed, professional sociology provides a solid theoretical foundation for expanding this direction. Therefore, we should stand on the base of the professional ethics theories of comprehensive functionalism, conflict theory, and ecology theory, treat teacher's professional ethics as a social phenomenon within specific historical and cultural processes, and summarize into four categories: universal and special, symbolic and substantive, social and individual, internal and external, thus providing cognitive tools for analyzing teacher' s professional ethics phenomena from a group perspective.

Objective: To analyze the clinical characteristics of nasopharyngeal carcinoma patients in Yunnan on the basis of the clinical data of hospitalized patients, and provide a basis for preventive measures. Methods: The clinical data of 2 499 patients with nasopharyngeal carcinoma diagnosed by pathology in Yunnan Cancer Hospital from January 2013 to December 2021 were collected. The incidence trend, region, ethnic distribution, gender and age, family history, first diagnosis symptoms, pathological type, clinical stage, EB virus and EGFR expression were analyzed. Results: Among the patients with the nasopharyngeal carcinoma in Yunnan, the ratio of male to female was 2.5∶1, the average age of onset was 49 years old, and the highest age of onset was 41-50 years old. The clinical manifestations were mainly nasal symptoms and neck symptoms. The pathological type was mainly non-keratinizing squamous cell carcinoma, the positive rate of EGFR immunohistochemistry was high (91.57%), the positive rate of EB virus was nearly 60 %, and the clinical stage was mainly stage III (45.06%) and stage IV (27.45%). Conclusion: The incidence of nasopharyngeal carcinoma in Yunnan is related to EB virus. The positive rate of EGFR is high. It is among the middle-aged and elderly men that the incidence rate of the disease is highest, with the majority being locally advanced patients locally advanced patients and most of them have the cervical lymph node metastasis at the first visit.

Objective　To explore the most appropriate total cumulative nedaplatin dose during chemotherapy for patients at the III-IVA stage after induced chemotherapy，and to analyze the effect of the total amount of nedaplatin on the prognosis of nasopharyngeal carcinoma patients after induction chemotherapy. Methods　In this study，a total of 109 patients who were first diagnosed at Yunnan Cancer Hospital from 2013 to 2018 received induction chemotherapy （ IC） plus concurrent chemoradiotherapy （ CCRT） . According to the CND quartile，the patients were divided into three groups：low （≤120 mg/m2），medium （121-200 mg/m2） and high dose （ > 200 mg/m2） . According to the response after tumor induction chemotherapy，the Nedaplatin group was divided into CR/PR and SD/PD subgroups，respectively. The effects of different cumulative dose of nedaplatin on the prognosis of patients after induction chemotherapy were analyzed to obtain the optimal CND. Results　The difference in survival rates between the low，medium and high dose groups of CND were not statistically significant （P > 0.05）. According to the survival analysis of CR/PR and SD/PD groups，the cumulative OS rates were 77.2% and 50.0%，the 3-year OS rates were 98.2% and 62.9%，the cumulative PFS rates were 63.2% and 45.0%，and the 3 a PFS rates were 77.2% and 54.8%，respectively. The survival rate of CR/PR group was better than that of SD/PD group （P < 0.05）. According to the low，medium and high dose of CND，the two subgroups were analyzed respectively. The cumulative OS rate of CR/PR subgroup was 93.3%，93.8% and 60.0% （P = 0.046），and the 3 year OS rates were 100.0%，93.8% and 100.0% （P > 0.05）. The cumulative PFS rates were 86.7%，78.1% and 30.0% （P = 0.007），and the 3 year PFS rates were 93.3%，90.6% and 60.0% （P = 0.017） . The low-dose and medium-dose groups showed significant advantages in OS rate， PFS rate and 3year PFS rate. There was no significant difference in survival rate among SD/PD subgroups （ P > 0.05） . In multivariate analysis， efficacy evaluation after IC （CR/PR&SD/PD） was an independent prognostic factor for OS，3 year OS，PFS，and 3 year PFS in patients with stage III-IVA nasopharyngeal carcinoma （P < 0.05） . Conclusion　The survival benefit of CR/PR patients with stage III-IVA nasopharyngeal carcinoma after IC is much better than that of SD/PD patients. Tumor response after IC （ CR/PR&SD/PD） is an independent prognostic factor for stage III-IVA nasopharyngeal carcinoma patients. In the post-IC CR/PR subgroup of patients with stage III-IVA nasopharyngeal carcinoma，the survival rate of patients receiving low and medium CND improved significantly in the higher dose group. It seems that CND does not need to exceed 200 mg/m² to achieve better survival results for these patients. [ABSTRACT FROM AUTHOR]

The effects of the interaction of light intensity and acid rain on the growth and biomass distribution of Schima superba seedlings were studied under three light conditions[100% natural light（L1）, 50% natural light（L2）, and 20% natural light（L3）] and three acid rain gradients [severe acid rain（pH 2.5, A1）, moderate acid rain（pH 4.0, A2）, and mild acid rain（pH 5.6, A3）]. Seedlings grown at pH 7.0（ACK） were used as the control. The results after 150 d of stress were as follows: light intensity had a very significant effect（P＜ 0.01）on the height and ground diameter of S. superba seedlings, whereas acid rain had a significant effect（P＜0.05） only on the ground diameter. There was no significant effect of the interaction between light intensity and acid rain on the seedling height and ground diameter. Light intensity had a significant impact（P＜0.01） on the biomass of each organ of the seedlings. Shading inhibited overall seedling growth. Whereas acid rain had a significant effect（P＜0.01） only on the leaf and stem biomass. Additionally, light intensity and acid rain had a significant（P＜0.05） interaction on leaf biomass, however, there was an extremely significant（P＜0.01） interaction effect on stem biomass. The severe acid rain（A1） gradient significantly decreased the stem biomass of seedlings by 48.8%, 13.8%, and 32.2% and increased the leaf biomass by 24.4%, 37.0%, and 7.6% under L1, L2, and L3, respectively, compared to the control. Light intensity and acid rain, as well as their interactions, had significant impacts（P＜0.01） on the stem-to-weight and stem-to-root ratios. The inhibitory or promotive effect of acid rain depends on the light environment, pH value, and the seedling organs. The promotive effects of acid rain were noticeable under moderate shade conditions. [ABSTRACT FROM AUTHOR]

[Objectives] Rice seeds carrying pathogens is an important way of spreading rice bakanae pathogens. The research aimed to reveal the situation of seed-borne rice bakanae pathogens in Jiangsu Province,China.[Methods] The seeds of 103 rice cultivars harvested from Jiangsu Province in 2017 were analyzed by loop-mediated isothermal amplification (LAMP) assays for specific detection of four known rice bakanae pathogen species,including Fusarium fujikuroi,F.proliferatum,F.verticilliodes and F.andiyazi.[Results] Among the 103 seed samples,89 seed samples were detected with rice bakanae pathogens. The most frequent species was F.fujikuroi,representing 83.5% of the total samples tested. The detection rates of F.proliferatum,F.verticillides,and F.andiyazi were low,i.e.,15.5%,1.9% and 1.9%,respectively.[Conclusions] Rice seeds carrying rice bakanae pathogens is common in Jiangsu Province,and F.fujikuroi is the most dominant pathogen,followed by F.proliferatum. Seed-borne of the two pathogens are an important primary infection source of rice bakanae. The results of this study provide important reference value for prevention and treatment of the rice bakanae in Jiangsu Province. [ABSTRACT FROM AUTHOR]

Teachers' tenacity plays an important role in both reducing teacher dropout rate and promoting teachers' sustainable professional development. Selecting nine novice teachers from a rural school in Y City, H Province as the object of the study, this study focuses on the development mechanism of novice teachers from the perspective of social ecosystem theory. The study finds that the dilemmas the novice teachers encounter at the beginning of their work are various and complex and the novice teachers develop their tenacity in the course of the interacting with dilemmas. The developmental level of the interviewed novice teachers' tenacity they showed in different situations can be divided into three stages: the enthusiastic stage, differentiated stage and stable stage. In each stage, the development of tenacity of challenger-type, accommodator-type and sideliner-type teachers is the result of their interaction in micro, medium and macro ecosystems, which presents a continuum pattern, and the quality of their interaction influences the development of the novice teachers' tenacity.
