As a new interdisciplinary course, the current paper writing course for medical postgraduates exhibits certaln disadvantages. For example, the course does not well target the learners' needs because of the absence of the needs analysis before class;English or biomedical teachers fall to combine English with medicine, thus unable to provide ideal courses. As textbooks are an important means to improve the quality of the course, one way to reform the course is to compile high-quality textbooks by interdisciplinary talents. Meanwhile, the compiling process should be guided by needs analysis as well as the teaching and editing experiences. In addition, the textbooks need to be con-tinuously improved in teaching practice.

The course of medical English fundamental reading carefully chooses reading materials from original English medical textbooks as the course materials, aiming at imparting the skills for reading biomedical English literature, and meeting the reading needs of medical undergraduates. In conducting this course, formative assessment is adopted, the frame of which is the theoretical model developed by Professor Wen Qiufang. There are three key phases in this model: setting up goals, eliciting learning evidence, and providing feedback. Three ways are employed to assess the course (symposium records, reflective journals and quizzes), which confirms that this model of formative assessment has improved the effectiveness of the course.

With globalization of biomedicine,Chinese postgraduates in medical colleges are facing increasing challenges.Writing and publishing research papers in English have become an essential requirement for their graduation and career development,but for non-native English speakers,having a good command of English for academic purposes (EAP) is of special difficulty.In China,lack of self-written textbooks is a bottleneck that restricts the teaching of EAP.Therefore,guided by EAP theories,this study carries out in-depth demand analysis for graduate students in medical colleges and universities,and designs a textbook framework with genre analysis theory.Based on self-established corpus finally completed an EAP writing textbook for postgraduates of biomedicine.This textbook and the writing and research process can provide implications for construction of EAP textbooks in other principles,thus promoting the all-round development of postgraduate education in China.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

Objective:To clarify the risk factors for post-operative central nervous system infection (PCNSI) to provide references for prevention and treatment of PCNSI.Methods:A total of 397 patients with neurosurgery diseases, admitted to and accepted 403 surgeries in our hospital from February 1 st, 2015 to December 30 th, 2015, were chosen in our study; their clinical data were collected. The incidence of PCNSI was analyzed. Risk factors for PCNSI were analyzed by univariate analysis and multivariate Logistic regression analysis. The ajusted specific infection rate of PCNSI was calculated in 12 chief surgeons who performed≥8 operations during the study period to assess the influence of surgeons in PCNSI incidence. Results:The PCNSI incidence in these 397 patients was 9.2% (37/403). The cerebrospinal fluid (CSF) culture positive rate was 29.7% (11/37), including 6 (54.6%) with positive gram staining. Univariate analysis showed that as compared with the non-infected group (366 surgeries), patients in the PCSNI group (37 surgeries) had significantly higher National Nosocomial Infections Surveillance (NNIS) scale, significantly higher proportion of patients with preoperative stay>6 d, significantly longer operative duration, and statistically higher proportion of involvement of scrub nurses with experience in fewer than 8 procedures ( P<0.05). Multivariate Logistic regression analysis showed operative duration ( OR=1.389, 95%CI: 1.202-1.606, P=0.000) and involvement of scrub nurses with experience in fewer than 8 procedures ( OR=2.860, 95%CI: 1.276-6.412, P=0.011) were independent risk factors for PCNSI. After adjustment by NNIS scale, the ajusted specific infection rate of PCNSI in 12 chief surgeons was 20.0%, 23.0%, 17.3%, 18.2%, 13.4%, 12.5%, 6.3%, 8.0%, 5.2%, 4.0%, 0.0%, and 0.0%, respectively, enjoying obvious differences. Conclusion:Specialized infection control training should give to surgeons with high adjusted specific infection rate of PCNSI; this training, shortening operative duration, and training of neurosurgery specialist nurses will be important measures to reduce PCNSI incidence.

Objective:To investigated the prevalence of anxiety and depression symptoms in patients with colorectal polyps in part of Xinjiang area and to explore the associated influencing factors related to psychological status, and to provide evidence and clues to promote the diagnosis and treatment of psychosomatic diseases in digestive system.Methods:From December 2021 to June 2022, at the First Affiliated Hospital of Shihezi University, the Fourth Division Hospital of Xinjiang Production and Construction Corps, the Third Division Hospital of Xinjiang Production and Construction Corps (Kashgar Hospital), the Thirteenth Division Red Star Hospital of Xinjiang Production and Construction Corps, the Tenth Division Beitun Hospital of Xinjiang Production and Construction Corps, the Seventh Division Hospital of Xinjiang Production and Construction Corps, the Fifth Division Hospital of Xinjiang Production and Construction Corps, patients who underwent colonoscopy and colorectal polyps detected were enrolled. The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

OBJECTIVE To standardize the English translations of the current Chinese patent medicine （CPM） instructions in order to increase its English translation quality and improve its readability. METHODS In an attempt to standardize its English translation， 64 CPM instructions were collected as samples for translation projects in Trados， using its two core functions of translation memory and terminology， combined with pre-editing （PRE） and post-editing （PE） skills. RESULTS The results showed that translation projects had up to 21.65% perfect match. Based on translation project practice， it is proposed to use the free translation or transcreation plus transliteration method to translate product names of CPM， and apply two human-computer interaction translation modes：“ machine translation （MT）+computer-assisted translation （CAT）+PE” and “PRE+MT+CAT+PE”， which are adopted in the translation of weak literary sections and strong literary sections， respectively. CONCLUSIONS The application of CAT not only improves the translation quality and the translation mode， reduces the translation cost， and maintains the consistency and style of the translation， but also accumulates language assets for future use， providing a novel reference for translating traditional Chinese medicine literature.

ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study. MethodHepG2 cells were treated with M36 at different concentrations （0， 2， 4， 6， 8， 10 μmol·L^-1）. Firstly， the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium （MTT）， colony formation assay， and EdU proliferation assay. Hoechst staining， flow cytometry analysis， and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally， Western blot was used to detect protein expression of cancer-related signaling pathways. ResultCompared with the blank group， M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells （P<0.01）， and the half inhibitory concentration （IC₅₀） value of M36 for 48 h was 5.03 μmol·L^-1， in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L^-1 M36 for 48 hours， the apoptosis rate of HepG2 cells was （42.03±9.65）% （P<0.01）. Compared with the blank group， HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase （cleaved-PARP） protein levels （P<0.01）. Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h compared with the blank group （P<0.01）， which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ （LC3 Ⅱ）. Western blot results showed that compared with the blank group， the levels of phosphorylated extracellular regulated protein kinase （p-ERK）， phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）， phosphorylated c-Jun N-terminal kinase （p-JNK）， and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group （P<0.05， P<0.01）. The mechanism may be related to the up-regulation of MAPK signaling pathway. ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy， which may be related to the activation of the MAPK signaling pathway.
