Objective To study a quick and effective assessing method used in the emergency trauma patients in order to prevent delaying treatment for patients from overlook or misdiagnosis during triage. Method From 1 January 2006 to 31 September 2006, there were 4023 patients evaluated with trauma assessment method, which was composed of CRAMS scale and trauma assessment program. Results Of 4023 patients, there were 2430 cases with CRAMS below 1( < 7) ,of whom 1979 cases assessed with trauma assessment program were found to be injuried severely to threaten their lives. And more noticeably,of 1593 patients with CRAMS ≥7 there were 46 patients found to have life-threatening injuries assessed with trauma assessment method. Conclutions CRAMS score can be used for triage, and trauma assessment program can be used to evaluate the injuries anatomically. Trauma assessment program and CRAMS employed conjointly can increase the sensitivity and specificity for the stratification of the severity in the injuried patients in order to get a successful triage and lo take advantage of the resources of e-mergency care appropriately.

Objective To investigate the clinicial significance of continuous glucose monitoring(CGM)of patients with severe traumatic brain injury(sTBI). Methods By glucose monitoring method,80 patients with sTBI〔Glasgow coma score(GCS)3-8〕in Department of Critical Care Medicine of Qingyuan People's Hospital in Guangdong Province from January 2012 to December 2012 were divided into two groups:41 patients in CGM group and 39 in regular glucose monitoring(RGM)group. The continuous glucose monitoring system(CGMS)was applied to monitor glucose level in the CGM group,and the finger blood was taken by portable blood glucose meter in the RGM group. The two groups were treated with insulin on the basis of glucose level,respectively. The relationships between the condition of glycemic excursions and the acute physiology and chronic health evaluationⅡ(APACHEⅡ)score or prognosis and between the incidence of hypoglycemia and prognosis were seen in the two groups. Results The close linear correlations between APACHEⅡ score and glycemic excursion in two groups,i.e. mean amplitude of glycemic excursions(MAGE)and coefficient of variation of glucose(GluCV),were documented(both P<0.05). The MAGE of the especially severe patients(GCS 3-5)was obviously higher than that of severe ones(GCS 6-8),and with the increase of APACHEⅡ score,the MAGE of patients was gradually elevated,the difference being statistically significant(both P<0.05). The incidence of hypoglycemia(7.32%vs. 23.08%)and fatality rate of 30 days(12.20%vs. 30.77%)in CGM group were lower than those of RGM group(both P<0.05). The MAGE and fatality rate of 30 days were positively correlated in CGM group(r=0.597,P=0.007),and the GLuCV and fatality rate of 30 days were positively correlated in RGM group(r=0.622,P=0.019). Conclusion CGM is beneficial to timely observe condition of glycemic excursions in sTBI patients and avoid occurrence of hypoglycemia or hyperglycemia,guiding the treatment of insulin and improving patients' prognosis.

Objective :
To learn the characteristics of second-line drug resistance and related gene mutations of multidrug-resistant Mycobacterium tuberculosis ( MDR-TB ) Beijing genotype strains.
Methods:
The MDR-TB isolates in Hwa Mei Hospital from 2017 to 2019 were enrolled and detected using RD105 deletion-targeted multiplex polymerase chain reaction (PCR). The proportion method for drug susceptibility test was used to detect the drug-resistant profiles against kanamycin, amikacin, capreomycin, ofloxacin and levofloxacin. The gene sequencing of rrs, tlyA, eis, gidB, gyrA and gyrB was conducted by PCR compared with H37RV strain. The differences in the rates of drug resistance and mutation between Beijing and non-Beijing genotype strains were examined to understand the characteristics of Beijing genotype strains.
Results:
There were 106 Beijing genotype and 27 non-Beijing genotype strains in 133 MDR-TB isolates. The drug resistance rates of kanamycin, amikacin, capreomycin, ofloxacin and levofloxacin in Beijing genotype strains were 9.43%, 7.55%, 3.77%, 32.08% and 32.08%, respectively. The rates of quasi-extensive and extensive drug resistance in Beijing genotype strains were 30.19% and 7.55%. The gene mutation rates of rrs, tlyA, eis, gidB, gyrA and gyrB in Beijing genotype strains were 7.55%, 7.55%, 1.89%, 2.83%, 36.79% and 2.83%, respectively. There were no significantly differences between Beijing and Non-Beijing genotype strains in the factors above ( P>0.05 ). The gene rrs, tlyA, eis, gidB, gyrA and gyrB had 2, 1, 2, 2, 5 and 3 mutation types, respectively, with single base substitution as the main type.
Conclusion
Beijing genotype strains are dominant in MDR-TB, with high resistance to fluoroquinolones and mainly gyrA gene mutation.

Objective To investigate the correlation between carotid intraplaque neovascularization and acute ischemic cerebrovascular disease. Methods The patients examined with contrast-enhanced ultrasound were enroled and divided into either a symptomatic group or an asymptomatic group according to their cerebral ischemic symptoms. The patients were also divided into a low-echo group, an equal-echo group, and an heterogeneous echo group according to the plaque echo characteristics on conventional ultrasound. The carotid intraplaque neovascularization was evaluated with contrast-enhanced ultrasound. Multivariate logistic regression analysis was used to identify the correlation between carotid intraplaque neovascularization and acute ischemic cerebrovascular disease. Results A total of 73 patients with acute ischemic cerebrovascular disease were enroled, 32 patients in the symptoms group (19 ischemic stroke, 13 transient ischemic attack), 41 patients in the asymptomatic group. Plaque echo characteristics: low-echo 15, equal-echo 41, and heterogeneous echo 17. The proportions of the patients with plaque enhancement (84. 4% vs. 61. 0% ; χ2 = 4. 802, P = 0. 028) and enhanced intensity (21. 78 ± 8. 50 dB vs. 15. 93 ± 8. 82 dB; t = 2. 440, P = 0. 018) in the symptomatic group were significantly higher than those in the asymptomatic group. The proportions of the patients with enhanced plaque in the low-echo, equal-echo and heterogeneous echo group were 93. 3% , 58. 5% , and 82. 4% , respectively (χ2 = 7. 826, P = 0. 020 ). The low-echo group and heterogeneous echo group were significantly higher than the equal-echo group (al P < 0. 05), but there was no significant difference between the low-echo group and the heterogeneous echo group (P > 0. 05). The intraplaque enhanced intensities in the low-echo group, equal-echo group, and heterogeneous echo group were 22. 62 ± 9. 33 dB, 14. 38 ± 8. 02 dB, and 18. 15 ± 9. 64 dB, respectively (F = 3. 877, P = 0. 027). The low-echo group was significantly higher than the equal-echo group (P = 0. 024 ). Multivariate logistic regression analysis showed that carotid intraplaque neovascularization (odds ratio 3. 456, 95% confidence interval 1. 103 - 10. 828; P = 0. 033) was independently associated with acute ischemic cerebrovascular disease. Conclusions Carotid intraplaque neovascularization is closely associated with acute ischemic cerebrovascular disease.

Objective:
This study aims to investigate the impact of individual and family factors on anxiety and loneliness of middle school students during quarantine in the COVID-19 pandemic and to provide reference for discussing the possible effective intervention paths in the stress process of public health emergencies.
Methods:
A total of 11 596 students from junior and high schools in Shanghai were selected to complete the questionnaire with the stratified random cluster sampling method. Generalized Anxiety Disorder(GAD-7) and UCLA Loneliness Scale, University of California at Los Angeles(ULS-6) were used for the survey.
Results:
The prevalence of anxiety and loneliness were 34.78% and 52.44% respectively. The rate of anxiety and loneliness in girls (36.13%, 54.62%) was higher than that of boys (33.44%, 50.28%)(χ 2=17.03, 21.82, P<0.05). Logistic regression analysis showed that graduates (OR=1.34, 95%CI=1.18-1.52), students ranking in the middle (OR=1.25, 95%CI=1.08-1.45) or in the bottom 25% (OR=1.76, 95%CI=1.50-2.05), non only children in the family (OR=1.25, 95%CI=1.09-1.43) and low socioeconomic status (OR=1.42, 95%CI=1.23-1.65) were associated with increased risk of moderate and severe level of anxiety(P<0.05). Girls(OR=1.20, 95%CI=1.12-1.30), graduates(OR=1.13, 95%CI=1.04-1.24), non residents(OR=1.20, 95%CI=1.09-1.33), lower level of grades(OR=1.72, 95%CI=1.55-1.91) and not living with parents(OR=1.32, 95%CI=1.18-1.48) were associated with increased risk of loneliness(P<0.05).
Conclusion
During the quarantine period caused by the COVID-19 pandemic, negative emotions such as anxiety and loneliness among adolescents need attention, especially females, graduates, only children and students with low rankings or low socioeconomic status.

Objective:To investigate the levels and the clinical signficance of matrix metalloproteinase 3 (MMP-3) in different activities of rheumatoid arthritis (RA).Methods:Case-control study. A total of 130 patients [24 cases of male, 106 cases of female, age (52.98±13.24)years, the median age was 51 years] with RA diagnosed in the Department of Rheumatology from the Second Affiliated Hospital of Soochow University, Suzhou Hospital of Traditional Chinese Medicine and Suzhou Ninth People′s Hospital from 2017 to 2018, and 100 healthy controls [28 cases of male, 72 cases of female, age (45.04±11.55) years, the median age was 44 years] from the physical examination center of the Suzhou Ninth People′s Hospital. The basic clinical data was used to determine the MMP-3 on groups of RA patients and healthy controls by immunoturbidimetry. The discriminating validity of MMP-3 in disease was evaluated using receiver operating characteristic (ROC) curve analysis.Results:Compared with that in healthy controls[28.0 (21.7-36.1)ng/mL], the MMP-3 in the low groups [51.8(41.8-73.1)ng/mL] increased dramatically ( Z=2.942, P<0.01). However, there was no significant difference between the MMP-3 in remission patients [28.8 (21.9-38.7)ng/mL] compared with the healthy controls ( Z=1.09, P>0.05). The area under the curve (AUC) of MMP-3 for diagnosis of RA was 0.877. the sensitivity was 73.1%, and the specificity was 93%.The AUC of MMP-3 diagnosis of low groups was 0.906, the sensitivity was 77.8%, and the specificity was 88%. In addition, the MMP-3 level was correlated with CRP and ESR ( r=0.242, r=0.243), and it was significantly correlated with DAS 28 ( r=0.361). Conclusions:It was indicated that the level of MMP-3 increased with the severity of rheumatoid arthritis. And the clinically low level of MMP-3 in RA patients could be used to indicate the remission condition. Meanwhile, the serum MMP-3 was closely related to DAS28.
