To Study Juvenile xanthogranuloma (JXG) in the nasal cavity, raise the level of diagnosis and treatment for this disease. We reported a case with JXG and reviewed the literatures. JXG in nasal vestibule is ex tremely rare. Only three cases were reported before. After surgical removal,no recurrence was found over a 10-month follow-up. Clinical manifestations and imaging examination is nonspecific for JXG, and the diagnosis of the disease relies on pathological examination. Surgical resection is an effective treatment method.

OBJECTIVE: To study the relationship between negative life events and quality of life of tinnitus patients, and explore the role of negative life events in psychological counseling and rehabilitation of tinnitus. METHOD: Sixty-one cases of tinnitus patients and 61 normal controls were tested with tinnitus handicap inventory and life event scale, scores were compared and the associated analysis was made. RESULT: Stimulating quantity of negative life events in the tinnitus group, compared with the control group was statistically different (Z = -2.56. P < 0.05). The incidence of negative life events in the tinnitus group compared with the control group was no statistically different (chi2 = 0.05, P > 0.05). The incidence of abnormal scores of negative life events compared with the control group was statistically different (chi2 = 16.68, P < 0.01). Positive correlation in tinnitus group was found between scores of negative life events and scores of tinnitus handicap inventory (r = 0.41, P < 0.01). The higher the score of negative life events, the lower the quality of life with tinnitus patients. CONCLUSION Severity of negative life events and tinnitus is closely related, and negative life events can reduce the quality of tinnitus patients life. We should pay more attention to negative life events in psychological counseling with tinnitus patients. The intervention in negative life events can improve the quality of life. providing the targeted and individualized theory basis for tinnitus psychological counseling and rehabilitation.

The authors use the method of combination of PBL teaching and clinic practicing in practical teaching of the digestive system medical imaging.The process is divided in four steps.This method can greatly improve the learning efficiency of the students and get good teaching result.

Experience-oriented teaching approach was introduced into the bilingual course of medical imaging in order to improve the teaching effect.This approach was performed through English literature translation activities and scene-teaching.Meanwhile it points out that this approach has particular advantages in stimulating students' interest and initiative in study.

Objective To evaluate the teaching effects of case introduced method based on picture archiving and communication system (PACS) system in medical imaging course.Methods Totally 148 students (2009 grade) majored in five-year clinical medicine from Xiangya Medical College were divided into 10 groups; the 10 groups were taken randomly as control group (n=75) and experimental group (n=73).Control group used traditional teaching methods (film teaching) while experimental group used case introduced method based on PACS system.Effects of teaching between were evaluated by questionnaire and test.x2 test was used to compare students' theoretical test scores,with α level =0.05.Results Based on results of questionnaires,more students in experimental group than in control group hold that case introduced method based on PACS system can achieve the purpose of teaching,improve interests in learning,and strengthen the mastery of knowledge.Test scores showed that the percentage of students scored 90-100 and 80-89 (respectively 14％,75％) in experimental group was significantly higher than that in control group (respectively 5％,66％) (x2 =17.932,P=0.000).Conclusions Application of case introduced method based on PACS system in medical imaging course not only improve students' motivation to learn and their clinical ability,but also allow teachers to find and correct shortcomings of students timely,therefore,it is worth promoting.

Objective To investigate the teaching effect of‘index’teaching method used in practical teaching of the medical imaging.Methods A total of 178 medical undergraduates were selected this study,113 clinical medical students using‘index’teaching method were taken as experimental group while others 65 anesthesia medical students using traditional teaching method as control group.The teaching effect of‘index’teaching method was evaluated quantitatively and qualitatively by practical test and questionnaire survey.Results The test scors of experimental group were(80.3±16.5),obviously higher than those of(71.3±25.8)in control group(P＜0.05),especially instudents with low scores.Conclusion The new teaching method had obvious advantages in culturing the thinking of imaging diagnosis and in improving the ability to solve clinical practical problems,the‘index’teaching method was more effective than traditional teaching method.

OBJECTIVE: To investigate the features of nasal septum cellule in computed tomographic (CT) images and its clinical significance. METHOD: CT scans data of nasal septum in 173 patients were randomly obtained from January 2001 to June 2005. Prevalence and clinical features were summarized in the data of 19 patients with nasal septum cellule retrospectively. RESULT: (1) Nineteen cases with nasal septum cellule were found in 173 patients. (2) All nasal septum cellule of 19 cases located in perpendicular plate of the ethmoid bone, in which 8 cases located in upper part of nasal septum and 11 located in middle. (3) There were totally seven patients with nasal diseases related to nasal septum cellule, in which 3 cases with inflammation, 2 cases with bone fracture, 1 case with cholesterol granuloma, 1 case with mucocele. CONCLUSION Nasal septum cellule is an anatomic variation of nasal septum bone, and its features can provide further understanding of some diseases related to nasal septum cellule.

Objective:To explore the psychological status of medical staff during COVID-19 epidemic, so as to provide reference and scientific basis for carrying out further psychological intervention and ensuring the mental health of medical staff.Methods:By using convenient sampling method and the Stresss-Anxiety ubscale of Depression Anxiety Stress (DASS-21) , the mental health status of 615 medical staff was investigated by the way of questionnaire star from February 4 to 16, 2020. A total of 615 questionnaires were distributed and collected, and 615 were valid, with an effective recovery rate of 100%.Results:The detection rates of psychological stress and anxiety of medical staff were 13.82% (85/615) and 25.37% (156/615) , respectively. 31-40 years old and working in key departments were risk factors for psychological stress of medical staff ( OR=1.779, 2.127) ; Women, frequently washing hands with soap/hand sanitizer/disinfectant were protective factors for psychological stress ( OR=0.520, 0.528) . Medical staff working in designated hospitals and key departments were more likely to have anxiety ( OR=2.042, 2.702) ; The high fit of the mask to the face and bridge of the nose was a protective factor for the psychological anxiety of medical staff ( OR=0.500) . Conclusion:Medical staff show higher stress and anxiety during the epidemic of COVID-19. Psychological intervention should be carried out early, focusing on men, age 31 to 40, medical staff working in designated hospitals and key departments.

To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
 Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
 Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L 
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
 Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.
