ObjectiveTo analyze the epidemiological characteristics and the vaccination status of the cases in Jing’an District from 2017 to 2019， so as to provide reference basis for the strategy of prevention and control of varicella epidemic. MethodsDescriptive epidemiological methods were used to analyze the epidemiological characteristics of varicella in Jing’an District. The differences between the vaccinated group and the unvaccinated group were compared by statistical methods. ResultsA total of 2 508 cases of varicella were reported with an average annual incidence of 78.7/105 from 2017 to 2019. There was no significant difference in the incidence among the three years（χ2=5.535，P=0.063）. There were 1 308 males and 1 200 females， and sex ratio was 1.1∶1. The highest incidence occurred in the age group from 5 to 9 years old （562 cases， 479.3/105）. Two annual peaks occured in May and November. The incidence in the aged 18 and below decreased year by year. There was significant difference in the proportion among the three years（χ2=78.129， P<0.001）. The median interval from vaccination to onset was 5 years among the vaccinated cases. There was significant difference in the cases who received two doses of vaccine in three years（χ2=90.902， P<0.001）. ConclusionWe should strengthen the monitoring system and pay more attention to the epidemiological characteristics of varicella. The protective efficacy of two-doses vaccine needs to be systematically evaluated.

NAFLD fibrosis score is associated with high-risk coronary plaque in patients with NAFLD / 中华健康管理学杂志

Objective:To investigate the possible role of non-invasive fibrosis scoring systems for detecting high-risk plaque among patients with non-alcoholic fatty liver disease (NAFLD).Methods:A total of 477 consecutive asymptomatic subjects underwent a health checkup including coronary computed tomography angiography (CTA) and abdominal ultrasonography. Fatty liver was evaluated using ultrasonography, and the NAFLD fibrosis score (NFS) was calculated. Coronary stenosis and plaque were evaluated using coronary CTA.Results:Of the study population, 223 had NAFLD. Among the NAFLD patients, high-risk coronary plaque was more frequent in patients with high or intermediate NFS than those with low NFS (62.5% versus 24.0%, P<0.001). The adjusted odds ratio with 95% confidence interval of high-risk plaque was 3.24 (1.11-9.40) for the highest versus lowest quartile of NFS ( P=0.016). Among those without NAFLD, NFS was not associated with high-risk coronary plaque (C-statistic with NFS versus without NFS, 0.766 versus 0.764, P=0.715). Adding NFS to the traditional cardiovascular disease (CVD) risk model increased the C-statistics by 0.679 to 0.739 ( P=0.031). Conclusions:There was an independent association of NFS with high-risk coronary plaque in patients with NAFLD, suggesting its potential use to optimize management of patients with NAFLD.

Computed tomography-identified phenotypes of small airway obstructions in chronic obstructive pulmonary disease / 中华医学杂志(英文版)

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characteristic of small airway inflammation, obstruction, and emphysema. It is well known that spirometry alone cannot differentiate each separate component. Computed tomography (CT) is widely used to determine the extent of emphysema and small airway involvement in COPD. Compared with the pulmonary function test, small airway CT phenotypes can accurately reflect disease severity in patients with COPD, which is conducive to improving the prognosis of this disease. CT measurement of central airway morphology has been applied in clinical, epidemiologic, and genetic investigations as an inference of the presence and severity of small airway disease. This review will focus on presenting the current knowledge and methodologies in chest CT that aid in identifying discrete COPD phenotypes.

Histopathological and MRI characteristics of facial unidentified filling objects / 中华医学美学美容杂志

Objective:Unidentified filling objects (UFO) can cause adverse results including infections, overfilling, asymmetry, foreign body granulomas, dislocation or psychological panic. To remove UFO accurately, it is important to locate and identify the injected substances preoperatively. This study investigated the viability of using MRI to correctly locate and identify injected substances by relating MRI to gross and pathological microscopic examination.Methods:Eighty-two facial UFO patients from 2013 to 2017 were studied by the experts of the Department of Image, Xinhua Hospital of Dalian University. Five of the patients were male and seventy-seven were female. The age ranged from 17 to 58 years with average 29.4 years. They came to our hospital for removal of UFO after they had facial injective fillers in the illegal medial offices. The injected sites involved in the forehead, temple, malar, cheek, nose, nasolabial folds, and chin. All the patients＇ faces were examined with MRI preoperatively, using T1W, T2W and fat-suppressed sequences. Based on the guides of MRI, UFOs were removed with their capsules by open approach. Samples were recorded with digital pictures and then were fixed in 10% formalin solution for microscopic examination of HE stained slices.Results:Based on MRI, gross and microscopic examination, UFO were classified into 3 types, gel-like fillers, solid particles, and growth factors. Gel-like fillers appeared strongly hyperintense on T2 W and STIR sequences and hypointense on T1 W sequences. Grossly, they looked like gruel covered by altered soft tissue. Under the light microscope, many pieces of blue-stained material were dispersed in subcutaneous tissue infiltrated with a large number of mononuclear cells and foreign-body giant cells. Solid particles had low to intermediate signal intensity on T1 W and T2 W images. Grossly, they were like sand merging in soft tissue. The biopsy showed crowed bubbles surrounded by tissue filled with a large number of mononuclear cells and foreign-body giant cells. For growth factors affected tissue, it was hard to differentiate between normal and abnormal on MRI. The affected tissue appeared as somehow hypointense on T1 W sequences and hyperintense on T2 W fat suppressed sequences. During the operation, the affected region was easy bleeding and full of fibrofatty tissue. Under the microscope, there were increased small blood vessels and collagens.Conclusions:Based on MRI, gross and microscopic examination, UFO can be classified into 3 types, gel-like fillers, solid particles, and growth factors. MRI is very important for doctors to assess the patient＇s conditions and make the plan of operation. MRI is also useful for doctors to locate UFO and understand the relationship between UFO and their nearby organs.

@#Objective: To detect the mutation of epidermal growth factor receptor (EGFR) gene in peripheral blood of non-small cell lung cancer (NSCLC) patients in Yunnan area with Super-ARMS, and to explore its correlation with clinicopathological characteristics. Methods: A total of 222 blood samples from patients with NSCLC were collected between January 2017 to December 2018 in the Molecular Diagnostic Center of Yunnan Cancer Hospital. The EGFR gene mutation in peripheral blood samples was detected by SuperARMS, and the relationship between EGFR gene mutation and clinicopathological features was analyzed. Meanwhile, the independent risk factors influencing EFGR mutation were also analyzed. Results: In the peripheral blood of 222 NSCLC patients, there were 81 cases (36.5%) with EGFR gene mutation. Among them, exon 19 deletion and L858R gene point mutation were the most common (75.3% of total mutation); female patients had a higher mutation rate than male patients (45.9% vs 27.0%); patients <60 years old had a higher incidence of mutation than patients≥60 years old (43.2% vs 28.8%) (P<0.05 or P<0.01); moreover, patients with no history of smoking, no history of radical surgery, adenocarcinoma, advanced stage and no history of chemotherapy had higher incidence of EGFR mutation (43.9% vs 21.6%, 39.2% vs 21.2%, 43.9% vs 4.8%, 39.7% vs 23.3% and 44.0% vs 23.5%) (P<0.05 or P<0.01). Multivariate logistic analysis showed that young, no smoking history, adenocarcinoma and no surgical history were independent risk factors for EGFR gene mutation (all P<0.01). Conclusion: In the peripheral blood of patients with NSCLC in Yunnan, the mutation rate of EGFR gene is higher in patients with age<60 years old, adenocarcinoma and non-smoking. Super-ARMS method is more sensitive in the detection of EGFR mutation in peripheral blood of lung cancer patients.

Strategy of the Causes of Death of Dependents / 法医学杂志

Objective To discuss the methods and strategies to identify the causes of dependents' deaths, as well as provide the experiences that can be used for reference and scientific basis for the forensic identification of the potentially growing deaths of the same kind in the future. Methods The 13 cases concerning death of dependents accepted by Sun Yat-sen University Forensic Center were collected, and the basic information of the dependents were statistically described. The nutritional status, environmental condition and medical care condition were evaluated according to dietary energy, living space, environment and medical treatment condition. Results Among the 13 dependents, there were 11 males and 2 females, with the oldest 74 and the youngest 9 and dwelling time was from 0.4 to 5.6 years. Forensic pathological examination showed that 13 dependents had infectious diseases and 11 were severely dystrophic. There were no fatal mechanical injuries or poisoning in dependents. Molecular pathological screening of 4 cases revealed no pathogenic variants of sudden death susceptible genes. The poor status of the diet, nutrition, living environment and medical care of these dependents were discovered. The direct cause of death of all 13 dependents was identified to be disease. The lack of nutrition, poor living environment and lack of medical care were thought to play a dominant role in causing the deaths of 12 dependants. Conclusion The death identification should follow the judicial procedure. In identification of the causes of death and analysis of the proportion of the affecting factors resulting in death, all factors, including nutrition,environment, medical care, injury and diseases, need to be considered.

Upregulation of miR-498 suppresses Th17 cell differentiation by targeting STAT3 in rheumatoid arthritis patients / 生理学报

To investigate the effect and mechanism of miR-498 on Th17 cell differentiation of peripheral blood mononuclear cells (PMBCs) in rheumatoid arthritis (RA) patients, peripheral blood samples were collected from RA patients and healthy controls, respectively. The proportion of CD4IL-17 T cells (Th17 cells) or CD4FOXP3 T cells (Tregs) in T cells and the Th17/Treg ratio were identified by the flow cytometer. The STAT3 and miR-498 expression were measured by Western blot and real-time PCR, respectively. ELISA was used to detect IL-17 concentrations. Luciferase assay was performed to confirm that miR-498 directly targeted the 3' untranslated region (3'UTR) of STAT3 in CD4 T cells. The effect of miR-498 on Th17 cell differentiation was explored by transfection of miR-498 mimic and/or pcDNA-STAT3 into CD4 T cells. In PMBCs of RA patients, the Th17/CD4 T cell ratio was significantly increased, while the Tregs/CD4 T cell ratio was obviously decreased, leading to a higher Th17/Treg ratio. The results showed a reduced miR-498 expression and an increased STAT3 protein expression in PMBCs, and an increased IL-17 concentration in serum of RA patients. In cells transfected with wild-type-STAT3-LU, miR-498 mimic significantly reduced the luciferase activity, STAT3 gene and protein expression, and miR-498 inhibitor had an opposite function. While the miR-498 mimic/inhibitor had no effect on the luciferase activity and STAT3 expression in cells transfected with mutant-STAT3-LU. CD4 T cells transfected with miR-498 mimic had a lower Th17/CD4 T cell ratio and IL-17 concentration, however, transfection of pcDNA-STAT3 reversed the effect of miR-498 mimic on Th17/CD4 T cell ratio and IL-17 concentration. These results suggest that overexpression of miR-498 suppresses Th17 cell differentiation by targeting STAT3 in RA patients.

Research Progress of the Correlation between Caveolin and Unexpected Sudden Cardiac Death / 法医学杂志

Due to the negative autopsy and without cardiac structural abnormalities, unexpected sudden cardiac death （USCD） is always a tough issue for forensic pathological expertise. USCD may be associated with parts of fatal arrhythmic diseases. These arrhythmic diseases may be caused by disorders of cardiac ion channels or channel-related proteins. Caveolin can combine with multiple myocardial ion channel proteins through its scaffolding regions and plays an important role in maintaining the depolarization and repolarization of cardiac action potential. When the structure and function of caveolin are affected by gene mutations or abnormal protein expression, the functions of the regulated ion channels are correspondingly impaired, which leads to the occurrence of multiple channelopathies, arrhythmia or even sudden cardiac death. It is important to study the effects of caveolin on the functions of ion channels for exploring the mechanisms of malignant arrhythmia and sudden cardiac death.
