Objective: To explore the coping strategies of students of military medical university, and the relationship between coping strategies and mental health. Methods: 4786 students of military medical university were assessed with the Simplified Coping Style and SCL-90. Results: 30～40% of the student chose active strategies when facing stresses. Fewer students adopt negative strategies (2～38%). The SCL-90 score of the students of military medical university were lower than students of other military schools. Positive coping strategies were associated with less SCL-90 score (fewer somatic and mental discomfort).Conclusion:Coping strategies are associated with mental health in student of military medical university.

Objective: To investigate the status of the quality of life (QOL) and its related factors of graduate students in military medical universities. Methods: 189 graduate students of a military medical university were assessed with WHO Quality of Life-BREF, Eysenck Personality Questionnaire (EPQ), Life Event Scale, Perceived Social Support Scale, and Simplified Coping Style Questionnaire. Results: The scores of QOL of graduate students in the military medical university were higher than average; The four domains of QOL were significantly correlated with introversion- extroversion, neuroticism, life event, social support, and coping style. The result from multiple regression showed that introversion- extroversion, neuroticism, social support, life event, and negative coping style were main factors influencing QOL. Conclusion: The status of the QOL of graduate students in military medical universities was pretty good; Their QOL could be improved by these factors, such as keeping stable emotion, developing extroversion, seeking social support, relieving the influence of bad life event, reducing negative coping behavior.

Objective:To evaluate the effects of different growth conditions on E.faecalis growth in the microfluid chip and the penetration of E.faecalis into microtubes.Methods:Four units on the chip were randomly selected as control,BHI,nutrient-Tdeprived (PBS) and pH 10 groups.The growth of E.faecalis was monitored by microscope for a period of 72 h after the suspension of E.faecalis had been added into the chip.Results:The microscopic analysis showed a distinct variation in the growth rate and morphological feature under different experimental conditions.he depth of bacterial penetration was significantly greater in BHI group.Conclusion:This study demonstrated that environmental changes can significantly influence the growth and penetration of E.faecalis into the micro tubes.

Drooling in waking in children older than 4 years is considered as abnormal, which may be resulted from the saliva control barriers in children with cerebral palsy, and impair their nutrition, sociality and mental health, etc. Evaluation of salivation can be subjective and objective, which including visual analogue scale, Teacher Drooling Scale, Drooling Frequency and Severity Scale, drooling quotient and Drooling Impact Scale, etc., in the former, and Saxon test and swab approach, etc., in the latter. The treatment mainly included oral move-ment training, correcting pathological factors, biofeedback, medicine and surgery. Physiotherapy and acupuncture were also reported for sali-vation in children with cerebral palsy.

Objective:To investigate the effect of fluid resuscitation and circulatory support, directed by different target mean arterial pressure (MAP), on abdominal blood flow, gastrointestinal function and inflammatory response in septic shock patients with hypertension.Methods:A prospective randomized controlled study was conducted. Hypertensive patients with septic shock admitted to the department of intensive care unit (ICU) of Liuzhou People's Hospital from January 1, 2019 to May 31, 2020 were enrolled. Patients were randomly divided into the low MAP groups (low standard group, LS group) or high MAP group (high standard group, HS group). According to the Surviving Sepsis Campaign Guidelines in 2016 and the updated guideline in 2018, all patients were given treatment of primary disease, fluid resuscitation, supportive management. The target MAP was 65-70 mmHg (1 mmHg = 0.133 kPa) in LS group, and was 75-80 mmHg in HS group. Acute gastrointestinal function injury (AGI) classification was performed on the 1st, 3rd and 7th day. The mean flow rate (Vm) and resistance index (RI) of superior mesenteric artery were evaluated using ultrasound, and the gastrointestinal function was dynamically evaluated using the modified single section ultrasonic gastric antrum method. The gastric antrum movement index (MI) and gastric empaging time (GET) were recorded. The levels of inflammatory markers in serum were detected by enzyme linked immunosorbent assay (ELISA), such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), procalcitonin (PCT) and vascular endothelial growth factor (VEGF). The target MAP, the days of use of vasopressors and the amount of fluid resuscitation were recorded.Results:A total of 208 hypertensive patients with septic shock were enrolled, including 109 in the LS group and 99 in the HS group. There were no significant differences in gender, age, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score between the two groups when diagnosed. After treatment, there was no significant difference in AGI classification between the LS group and HS group on the 1st day. On the 3rd and 7th day, there were statistical differences between the two groups (3rd day: proportion of Ⅰ, Ⅱ, Ⅲ, Ⅳ grades were 25.69%, 56.88%, 11.93%, 5.50% in LS group, 15.15%, 54.55%, 25.25%, 5.05% in HS group, respectively, χ 2 = 7.900, P = 0.048; 7rd day: proportion of Ⅰ, Ⅱ, Ⅲ, Ⅳ grades were 44.96%, 49.54%, 3.67%, 1.83% in LS group, 31.31%, 52.53%, 11.11%, 5.05% in HS group, respectively, χ 2 = 8.178, P = 0.042). The Vm of superior mesenteric artery was higher and the RI was lower in the LS group than those in the HS group on day 1, 3 and 7 [Vm (cm/s): 21.72±3.02 vs. 19.50±2.83, 20.42±2.62 vs. 17.02±1.99, 26.52±2.70 vs. 22.47±4.03; RI: 0.86±0.05 vs. 0.92±0.04, 0.87±0.05 vs. 0.95±0.05, 0.81±0.03 vs. 0.85±0.03, all P < 0.01]. The MI was higher and the GET was shorter in the LS group than those in the HS group on day 3 and day 7 [MI: 3.00±0.33 vs. 2.60±0.29, 4.50±0.51 vs. 3.90±0.33; GET (minutes): 86.01±19.78 vs. 100.99±25.01, 71.00±16.37 vs. 84.98±20.18, all P < 0.01]. In addition, the levels of serum TNF-α, IL-6, PCT, VEGF were lower in the LS group than those in the HS group after 3 days of treatment [TNF-α (ng/L): 147.05±28.32 vs. 256.99±27.04, IL-6 (ng/L): 762.99±57.83 vs. 1 112.30±118.32, PCT (μg/L): 37.00±5.58 vs. 56.00±12.36, VEGF (ng/L): 123.00±19.78 vs. 167.01±21.55, all P < 0.05]. The target MAP was maintained at (68.02±4.71) mmHg in LS group, and (79.04±3.04) mmHg in HS group. The difference between the two groups was statistically significant ( P < 0.01). Compared with the HS group, the days of using vasopressors was shorter in LS group (days: 3.50±1.27 vs. 4.55±1.47), and the amountof fluid was reduced significantly (mL: 1 602.29±275.49 vs. 2 000.30±272.59, both P < 0.01). Conclusion:Maintaining a low target mean arterial pressure (65-70 mmHg) in hypertensive patients with septic shock can improve blood supply of superior mesenteric artery, protect the gastrointestinal function, reduce the level of inflammatory factors, and diminish the duration of using vasopressors and the amount of fluid.

This paper was aimed to study the safety of moxibustion with FMEA method.Failure mode and effects analysis (FMEA) were used in every aspect of the operation process of moxibustion.And the local skin temperature was measured in 80 patients treated with moxa box moxibustion.The results showed that the skin temperature reached the highest when the moxibustion was given for 15 min,which was in consistence with the patients' chief complaints and their tolerances.It indicated that moxibustion for 15 min was the best moxibustion amount.Meanwhile,inspection should be made to avoid burning.After the application of FMEA,the RPN of the inspection activities,the temperature and distance of moxibustion were significantly decreased (P ＜ 0.05).It was concluded that the application of FMEA management mode strengthened the risk management of moxibustion treatment,standardized treatment process,provided the basis for the temperature and distance of moxibustion,and ensured the safety and efficacy of treatment.

Objective To explore the value of quantitative chest CT in early diagnosis of chronic obstructive pulmonary disease(COPD).Methods The clinical data of 138 cases of COPD high-risk patients in Shanghai community and COPD high-risk respondents in outpatient clinic of Zhongshan Hospital,Fudan University from September 20,2013 to May 20,2014 were retrospectively analyzed.All high-risk participants underwent pulmonary function and chest CT examination at baseline and 1 year later.Chest CT images were imported into quantitative CT analysis software to collect quantitative CT data.These participants were divided into COPD group(n=40)and non-COPD group(n=98)based on their lung functions after 1 year.The differences in baseline lung function and quantitative CT measurements between the two groups were compared.Binary logistic regression was used to analyze the predictors of COPD in high-risk individuals after 1 year of follow-up,and the efficacy of the logistic regression model was evaluated by ROC curve.Results There were no significant differences in gender,body mass index(BMI),the percentage value of forced expiratory volume in 1 second predicted(FEV1%pred),airway wall area ratio(WA%),total airway count(TAC),and airway wall thickness(WT)between the two groups at baseline.Compared to the non-COPD group,the square root of the tracheal wall area at 10 mm from the inner circumference of the airway(Pi10),(3.43[3.30,3.54]vs 3.23[3.15,3.36],P＜0.001),and the percentage area of low attenuation regions below ﹣950 HU(LAA%﹣950),(2.06[0.32,6.29]vs 0.57[0.25,1.89],P=0.015)were significantly higher in the COPD group.The mean lung density(MLD)in the COPD group was lower than that in the non-COPD group([﹣799.89±35.62]vs[﹣783.60±43.52],P=0.038).Binary logistic regression analysis indicated that age and Pi10 were risk factors for COPD(P＜0.05),with an area under the ROC curve of 0.791(95%CI 0.714-0.868).Conclusions In the COPD high-risk population with normal lung function,patients with elevated Pi10 and LAA%﹣950 have a higher incidence of COPD one year later,suggesting that quantitative chest CT measurements such as Pi10 and LAA%﹣950 can assist clinicians in identifying early-stage COPD.
