Viral myocarditis(VMC)is the leading cause of dilated cardiomyopathy,which can lead to heart failure and sudden cardiac death.With the development of high-throughput sequencing technology,non-coding RNA(ncRNA)plays an important role in the occurrence and development of VMC.ncRNA promotes the occurrence and development of VMC by regulating viral replication,immune cell function,myocardial cell death,myocardial interstitial fibrosis,and other pathological processes.This article reviews the research progress of ncRNA in VMC and provides new ideas for the pathogenesis,diagnosis,and treatment of VMC.

Objective:To investigate the effects of aloperine(ALO)on cell behavior of colorectal cancer(CRC)cells through IL-6/tyrosine kinase 1(JAK1)/signal transducer and activator of transcription 3(STAT3)pathway.Methods:SW480 cells were grouped into CK group(normal culture of SW480 cells),ALO low-dose group(ALO-L group,0.2 mmol/L),ALO medium-dose group(ALO-M group,0.4 mmol/L),ALO high-dose group(ALO-H group,0.8 mmol/L)and ALO-H+activator(IL-6 activator recombinant human IL-6 protein)group(0.8 mmol/L+100 ng/ml).Proliferation of SW480 cells was detected by CCK-8 and plate cloning experi-ments;apoptosis of SW480 cells was detected by flow cytometry;Western blot was used to detect expressions of proliferating cell nu-clear antigen(PCNA),Bcl-2-associated X protein(Bax),IL-6,p-JAK1,p-STAT3 proteins in cells.After the above five groups of cells were co-cultured with natural killer cells NK-92MI,respectively,they were named as CK co-culture group,ALO-L co-culture group,ALO-M co-culture group,ALO-H co-culture group,and ALO-H+activator co-culture group,respectively.Levels of TNF-α and IFN-γ in supernatant and immune killing rate of NK-92MI in the co-culture system were detected.Results:Compared with CK group,OD450 value,clone formation rate,protein expressions of PCNA,IL-6,p-JAK1,p-STAT3 in SW480 cells in ALO-L group,ALO-M group and ALO-H group were decreased,while apoptosis rate and protein expression of Bax were increased,in a dose-dependent manner(P<0.05);compared with ALO-H group,OD450 value,clone formation rate,protein expressions of PCNA,IL-6,p-JAK1,p-STAT3 in SW480 cells in ALO-H+activator were increased,while apoptosis rate and protein expression of Bax were decreased(P<0.05);compared with CK co-culture group,levels of TNF-α and IFN-γ in supernatant of cells,and the immune killing rate of NK-92MI cells in ALO-L co-culture group,ALO-M co-culture group and ALO-H co-culture group were increased,and in a dose-dependent manner(P<0.05);compared with ALO-H co-culture group,levels of TNF-α and IFN-γ in supernatant of cells,and immune killing rate of NK-92MI cells in ALO-H+activator co-culture group were decreased(P<0.05).Conclusion:ALO may inhibit the proliferation,immune escape and promote apoptosis of SW480 cells by inhibiting IL-6/JAK1/STAT3 signaling pathway.

From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".

OBJECTIVES: To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children. METHODS: Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH. RESULTS: A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819). CONCLUSIONS The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.

Objective: To analyze mortality and its trend of chronic respiratory diseases (CRD) in China from 1990 to 2019. Methods: Based on the provincial results of China from the 2019 Global Burden of Disease (GBD) study, the average annual percent change (AAPC) of standardized mortality rates of different CRDs were analyzed by using Joinpoint 4.8.0.1, and the age-standardized mortality rate of CRD was calculated by using the GBD 2019 world standard population. Based on the comparative risk assessment theory of GBD, the attributable deaths due to 12 CRD risk factors were estimated, including smoking, indoor air pollution, occupational gas exposure, particulates and smog exposure, environmental particulate pollution, low temperature, passive smoking, ozone pollution, occupational exposure to silica, occupational asthma, high body mass index, high temperature and occupational exposure to asbestos. Results: From 1990 to 2019, the number of deaths and standardized mortality of chronic obstructive pulmonary disease (COPD) showed a downward trend (P<0.001). The number of COPD deaths decreased from 1 244 000 (912 000 - 1 395 000) in 1990 to 1 037 000 (889 000 - 1 266 000) in 2019. AAPC=-0.9% (95%CI: -1.5% - -0.3%), P<0.001; The standardized mortality rate decreased from 217.9/100 000 (163.3/100 000 - 242.0/100 000) in 1990 to 65.2/100 000 (55.5/100 000 - 80.1/100 000) in 2019. AAPC= -4.2% (95%CI:-5.2% - -3.2%), P<0.001. The number of deaths from asthma decreased from 40 000 (30 000 - 58 000) in 1990 to 25 000 (20 000 - 31 000) in 2019. AAPC=-2.0% (95%CI: -2.6% - -1.4%), P<0.001; The standardized mortality rate of asthma decreased from 6.4/100 000 (4.7/100 000 - 9.5/100 000) in 1990 to 1.5/100 000 (1.2/100 000 - 1.9/100 000) in 2019. AAPC=-5.1% (95%CI: -5.8% - -4.4%), P<0.001. The number of pneumoconiosis deaths decreased from 11 000 (8 000 - 14 000) in 1990 to 10 000 (8 000 - 14 000) in 2019, AAPC=-0.2%(95%CI:-0.4% - 0.1%), P=0.200; The standardized mortality rate of pneumoconiosis decreased from 1.4/100 000 (1.0/100 000 - 1.7/100 000) in 1990 to 0.5/100 000 (0.4/100 000 - 0.7/100 000) in 2019. AAPC=-3.1% (95%CI: -3.4% - -2.8%), P<0.001. The number of deaths from pulmonary interstitial diseases and pulmonary sarcoidosis increased from 3 000 (3 000 - 6 000) in 1990 to 8 000 (6 000 - 10 000) in 2019, AAPC=3.5% (95%CI: 2.7% - 4.2%), P<0.001; The corresponding standardized mortality rate changed little from 1990 to 2019, and AAPC was not statistically significant.The age-standardized mortality rates of different CRDs were higher in men than those in women. In 1990 and 2019, the mortality rates of COPD, asthma, pneumoconiosis and interstitial pulmonary disease and pulmonary sarcoidosis increased with age. In 2019, the population attributable fractions (PAFs) for smoking, environmental particulate pollution, occupational gas exposure, particulate and smog exposure, low temperature exposure and passive smoking were 71.1% (68.0% - 74.3%), 24.7% (20.1% - 30.0%), 19.3% (13.0% - 25.4%), 15.7% (13.6% - 18.3%) and 8.8% (4.5% - 13.1%) respectively in men, and the PAFs for environmental particulate pollution, smoking, low temperature exposure, occupational gas exposure, particulate and smog exposure, and passive smoking were 24.1% (19.6% - 29.3%), 21.9% (18.7% - 25.2%), 16.4% (14.0% - 19.2%), 15.6% (10.2% - 21.1%) and 14.7% (7.9% - 21.3%) respectively in women. Conclusions: During 1990-2019, the overall death level of CRD decreased significantly in China, but it is still at high level in the world. Active prevention and control measures should be taken to reduce the death level caused by CRD.

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

BACKGROUND: Colorectal cancer (CRC) is the fourth cause of cancer death in China. We aimed to provide national and subnational estimates and changes of CRC premature mortality burden during 2005-2020. METHODS: Data from multi-source on the basis of the national surveillance mortality system were used to estimate mortality and years of life lost (YLL) of CRC in the Chinese population during 2005-2020. Estimates were generated and compared for 31 provincial-level administrative divisions in China. RESULTS: Estimated CRC deaths increased from 111.41 thousand in 2005 to 178.02 thousand in 2020; age-standardized mortality rate decreased from 10.01 per 100,000 in 2005 to 9.68 per 100,000 in 2020. Substantial reduction in CRC premature mortality burden, as measured by age-standardized YLL rate, was observed with a reduction of 10.20% nationwide. Marked differences were observed in the geographical patterns of provincial units, and they appeared to be obvious in areas with higher economic development. Population aging was the dominant driver which contributed to the increase in CRC deaths, followed by population growth and age-specific mortality change. CONCLUSIONS Substantial discrepancies were observed in the premature mortality burden of CRC across China. Targeted considerations were needed to promote a healthy lifestyle, expand cost-effective CRC early screening and diagnosis, and improve medical treatment to reduce CRC mortality among high-risk populations and regions with inadequate healthcare resources.

【Objective】To provide a rabbit model for dry eye using a dry environment induced by Controlled Drying System.【Methods】Twenty-four male New Zealand rabbits were used in the experiment. They were randomly divided into control group and dry group，each one with 12 rabbits. The dry group was randomly housed in Controlled Drying System（CDS）for 14 days. The relative humidity，airflow and temperature were kept at（22±4）%，3~4 m/s and（23~25）℃， respectively. The control group were fed in a normal environment where relative humidity，airflow and temperature were kept at 60%~70%，0.2 m/s and（23~25）℃. The Schirmer test，corneal fluorescein staining，conjunctival lissamine green staining were performed during the experimental process on days 0，3，7，and 14. On the last day，the rabbits were euthanized and the eye tissues were made into paraffin-cut sections. After staining，we evaluated the corneal epithelial thickness and goblet cell number in the conjunctiva using light microscopy. MUC5AC in the conjunctival epithelium was detected by immunofluorescence. The apoptosis level changes on the ocular surface were evaluated using Caspase- 3 by immunohistochemistry. 【Results】 Decreased tear production ，increased corneal fluorescein staining and increased conjunctival lissamine green staining were found on days 3，7，and 14 in the dry group compared with the control group（P < 0.001）. Corneal epithelial thickness of control group and dry group were （58.0±7.2）μ m and（47.8±7.6）μ m ，which showed corneal epithelial thickness of dry group was decreased（P＜0.05）. Goblet cells in the conjunctiva of control group and dry group were 15 ± 4 and 10 ± 2，which showed goblet cells of dry group was decreased（P＜0.01）. The expression of MUC5AC（consistent with goblet cells deficiency） was also reduced. Caspase- 3 was highly expressed on the corneal epithelium in the dry group. IOD/field of control group and dry group were（17±2）% and（20±2）%（P＜0.01）.【Conclusions】 Dry environment can make rabbits have pathological changes of dry eye on ocular surface epithelium. This dry eye model of rabbit caused by Controlled Drying System would be an effective tool to study the pathogenesis of dry eye.

【Objective】 To analyze the induction of glucose transporter 4(GLUT4) by Fusobacterium nucleatum(Fn) in esophageal squamous cell carcinoma(ESCC) and its correlation with clinicopathologic features and 5-year survival, and to explore its clinical significance and prognostic value. 【Methods】 Paraffin-embedded specimens of esophageal squamous cell carcinoma were collected from 96 patients with this disease from January 2014 to March 2015 at Anyang Cancer Hospital. RNAscope and immunohistochemistry were used to detect the expression of Fn and GLUT4 in Esophageal squamous cell carcinoma tissues, and to analyze the induced effect of Fn on GLUT4 and its correlation with clinicopathologic features. Survival curves were drawn by Kaplan-Meier survival analysis and correlation between GLUT4-induced effect of Fn and survival time was analyzed by Log-rank test. 【Results】 There were red granules in the cytoplasm of ESCC , which were positive for Fn infection, brown granules in the plasma membrane of ESCC were positive for GLUT4 expression, and the expression of GLUT4 was consistent with the Fn infection(P < 0.05). At the same time, the positive expression of GLUT4 induced by Fn was significantly correlated with gender, smoking, drinking, degree of differentiation, depth of invasion, lymph node metastasis and clinical stage(P < 0.05). The 5-year survival rate and median survival time in the positive group were significantly lower than those in the negative group(P < 0.05) . 【Conclusions】 Long-term smoking and drinking will lead to bad oral environment. Fn is more easily infected and planted in this environment, which can induce the high expression of GLUT4 in plasma membrane of cancer cells, enhance glucose metabolism, and promote the malignant progression of ESCC. Effective removal of Fn and inhibition of GLUT4 expression may provide a new strategy and effective treatment for esophageal squamous cell carcinoma.
