Objective: To explore the epidemic characteristics of injury related deaths in children and adolescents aged 1-24 years old in China from 2010 to 2020, so as to provide a basis for the formulation of policies and measures related to the control of injuries and deaths among children and adolescents. Methods: The data were sourced from the China Death Cause Monitoring Dataset from 2010 to 2020. Annual percentage change (APC) and average annual percentage change (AAPC) of injury deaths in China in this age group during the period 2010 to 2020 were analyzed by Join point regression. Results: From 2010 to 2020, the standardized death rate of injury showed a decreasing trend (AAPC=-6.90%, t =4.58, P <0.01). The standardized death rates of male and rural injuries showed an overall downward trend, with AAPC rates of -8.37% and -7.79%( t =11.87, 10.34, P <0.01). An increasing trend was observed in the 20-24 year-old age group during 2010-2018 (APC=18.11%, t =6.50, P <0.01). The death rate from injuries was higher in males than females, and higher in rural areas compared with urban areas ( χ 2=16 483.64, 3 268.65 , P <0.01). A downward trend was observed in accidental falls and suicide, the overall standardized mortality rate of traffic accidents, accidental poisoning, fire, drowning, homicide and other injuries (AAPC=-10.22%, -6.21%, -7.50%, -7.94%, -9.01% , -10.97%, t =16.23, 7.29, 2.53, 9.32, 7.88, 4.58, P <0.05). Conclusion From 2010 to 2020, the overall injury standardized mortality rate in the 1-24 year-old age group shows a decreasing trend, but it remains at a relatively high level. Prevention efforts should be continuously strengthened, especially for urban areas, and should focus on women and those aged 20-24 years old, as well as accidental falls and suicide prevention.

Background::The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients’ genders, ages, and durations.Methods::Dermoscopic images of 87 rosacea patients were collected in non-polarized and polarized dermoscopy contact modes at 20-fold magnification. Dermoscopic features, including vessels, scales, follicular findings, and other structures, were summarized and evaluated.Results::The reticular linear vessels and red diffuse structureless areas of ETR were distinctive. For PPR, red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules were typical dermoscopic criteria. The common dermoscopic features of PHR were: orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines. The following features statistically differed among the three rosacea subtypes: reticular linear vessels ( P < 0.001), unspecific linear vessels ( P= 0.005), linear vessels with branches ( P < 0.001), yellow scales ( P = 0.001), follicular plugs ( P < 0.001), perifollicular white color ( P < 0.001), red diffuse structureless areas ( P = 0.022), orange diffuse structureless areas ( P < 0.001), red focal structureless areas ( P = 0.002), orange focal structureless areas ( P = 0.003), white lines ( P < 0.001), follicular pustules ( P < 0.001), and black vellus hairs ( P < 0.001). Conclusions::The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.

Objective    To introduce a new type thoracic vest designed according to the incision characteristics of female patients undergoing totally thoracoscopic cardiac surgery. Methods    Sixty-one female patients undergoing totally thoracoscopic cardiac surgery from February 2019 to May 2020 in our department were enrolled. All female patients had hypermastia and (or) mastoptosis which covered the incision. They were randomly divided into a research group (group A, n=32) and a control group (group B, n=29). The group A used the new type thoracic vest, while the group B used the traditional single shoulder belt. The degree of satisfaction, visual analogue scale (VAS) score 24 hours after the thoracic drainage tube removed, the average time-consuming of dressing change, dressing frequency and the incision infection rate were compared between two groups. Results    The degree of satisfaction in the group A was higher than that of the group B (P<0.001). The VAS scores of pain, average time-consuming of dressing change and dressing frequency in the group A were less or lower than those of the group B (P<0.001). There was no statistical difference in the incision infection rate between the two groups (P=0.214), but incision infection rate of the group A was lower than that of the group B. Conclusion    The new type thoracic vest seems to be more beneficial for patients than traditional single shoulder belt. It is easy to use, increases the psychological satisfaction of patients, reduces the pain and the incision infection and improves work efficiency, which is worthy of clinical application.

Objective:To explore the relationship between microRNA-4429 (miR-4429) derived from serum exosomes and prognosis of radical radiation and chemotherapy for non-small cell lung cancer (NSCLC).Methods:309 blood samples of NSCLC patients were collected [before chemotherapy (T0), after 1 cycle of chemotherapy (T1) and after 2 cycles of chemotherapy (T2), 103 cases at each time point], and the expression level of miR-4429 was detected by real-time fluorescent quantitative PCR method, and the relationship between it and the prognosis of radical radiation and chemotherapy in NSCLC was analyzed.Results:The 1-year, 2-year and 3-year survival rates of 103 NSCLC patients were 69.90%, 45.63% and 34.95%, respectively. The expression levels of T1-miR-4429 and T2-miR-4429 in the survival group were 0.66±0.14 and 0.77±0.11, respectively, which were higher than T1-miR-4429 (0.60±0.06) and T2-miR-4429 (0.62±0.11) in the death group, and the differences were statistically significant ( t=2.269, 6.997, P<0.05). Restricted cubic spline fitting COX regression analysis showed that T2-miR-4429 had a linear relationship with survival in NSCLC. COX regression analysis showed that TNM staging was an independent risk factor for the survival and prognosis in NSCLC ( P<0.05), and the degree of differentiation, targeted therapy and T2-miR-4429 were all independent protective factors for the survival and prognosis in NSCLC ( P<0.05). The calibration curve of the nomogram regression model constructed by TNM stage, degree of differentiation, targeted therapy and T2-miR-4429 coincided well with the ideal curve, and the C-index was 0.713. Conclusions:The high expression level of T2-miR-4429 indicates that NSCLC patients have a low risk of poor survival prognosis. The nomogram regression model constructed by TNM staging, degree of differentiation, targeted therapy and T2-miR-4429 has a certain degree of discrimination and accuracy, which can assist in evaluating the prognosis of NSCLC.

Objective:To analyze the expression of mismatch repair genes MLH1 and PMS2 in elderly colorectal cancer patients and its association with the clinicopathological features.Methods:This study was a single-center retrospective cohort study.According to the loss of MLH1 and PMS2 gene expression, elderly patients with colorectal cancer admitted to Beijing Hospital from January 2014 to December 2018 were consecutively enrolled and divided into the MLH1 group(n=65)and the PMS2 group(n=80). Pathological features were compared between the MLH1 group, the PMS2 group and patients with normal MLH1 and PMS2 gene expression.Results:Among patients with the loss of MHL1 protein expression, pathological features were similar in males and females.A minority of patients(16.9%)had a family history of tumors.Most lesions were either moderately differentiated(63.1%)or poorly differentiated(24.6%). Regarding staging, 44.6% were in stage T4, 27.7% were in stage T3, 61.5% were in N0, 89.2% were in M0, and most patients were in TNM stage Ⅲ.Lesions were mostly located in the ascending colon(61.5%). Compared with patients with normal expression of MHL1, patients with the loss of MHL1 protein expression were younger[(74.6±8.8) years old vs.(77.3±6.2) years old, t=-2.072, P=0.040]and had greater maximal tumor length[(5.7±2.3) cm vs.(4.4±1.3) cm, t=3.753, P<0.001], and there were significant differences in lesion differentiation, T staging and tumor location between the two groups( P<0.05). Conclusions:Loss of MLH1 or PMS2 gene expression in elderly colorectal cancer patients is associated with an early age of onset, rapid tumor progression, poor differentiation, and pathological staging.

Objective? To explore the effects of "1+N" extended nursing on medication compliance, self-management ability and metabolic indicators among discharged type 2 diabetes patients. Methods? From October to December 2017, we selected 300 discharged type 2 diabetes patients from Department of Endocrinology from Shaanxi Provincial People's Hospital as subjects. All of the patients were divided into intervention group and control group with the method of random number table, 150 cases in each group. Control group carried out telephone follow-up post discharge. On the basis of telephone follow-up, intervention group implemented "1+N" extended nursing. We compared the fasting blood glucose (FBG), bisphosphoglyceric acid (BPG), glycosylated hemoglobin (HbA1c), body mass index (BMI), scores of 8-item Morisky Medication Adherence Scale (MMAS-8) and the scoring rate of Diabetes Self-care Scale (2-DSCS) of patients between two groups 6 months after follow-up. Results? After intervention, the FBG, BPG and BMI of intervention group were lower than those of control group with statistical differences (P＜0.05). The number of patients with the high level of compliance of MMAS-8 in intervention group was more than that in control group with a statistical difference (P＜0.05).The item scoring rate of 2-DSCS of patients in intervention group were higher than those in control group with statistical differences. Conclusions "1+N" extended nursing can improve metabolic indicators, medication compliance and self-management ability among type 2 diabetes patients.

Objective To investigate the protective function of edaravone in the compressed spinal cord.Methods There were 150 rabbits enrolled in each group in the experiment.Rabbits in both operation group and edaravone (EDA) treating group received mild spinal cord compressionby setting a flap head screw between C6 C7 after the neck.The spinal cord decompression was conducted seven days later.After 6 hours,rabbits in the EDA treating group were injected with a large amount of EDA through ear border veins,while the rabbits in the operation group only received 0.9％ sodium chloride injection.The transmission electron microscope was used to observe the apoptotic bodies at 1 day,3 days and 7 days after compression,and 1 day,3 days,7 days,and 14 days after decompression.Flow cytometry was used to test the rate of apoptosis of spinal cord cells.Immunohistochemistry was used to test the expression of Bax protein that is related to apoptosis.Results The neuronal apoptosis appeared after compression in both operation group and EDA-treating group.The Basso Beattie Bresnahan (BBB) score,neuronal apoptosis rates,and Bax protein expressions in both groups were statistically different (P ＜ 0.05) when the spinal cord was compressed in the first day and the third day,while there was no statistically different when spinal cord compressed at the seventh day (P ＞ 0.05).After decompression of the spinal cord,the BBB score,neuronal apoptosis rates,and Bax protein expressions in both groups were becoming lower at the seventh day (P ＜0.05).Conclusions EDA has protective function for compressed spinal cord.However,only the compression of spinal cord compression period of sufficient decompression can fundamentally protect the spinal cord.
