Background::Somatic copy number variations (SCNVs) in the CDKN2A gene are among the most frequent events in the dysplasia-carcinoma sequence of esophageal squamous cell carcinoma. However, whether CDKN2A SCNVs are useful biomarkers for the risk stratification and management of patients with esophageal squamous cell dysplasia (ESCdys) is unknown. This study aimed to investigate the characteristics and prognostic value of CDKN2A SCNVs in patients with mild or moderate (m/M) ESCdys. Methods::This study conducted a prospective multicenter study of 205 patients with a baseline diagnosis of m/M ESCdys in five high-risk regions of China (Ci County, Hebei Province; Yanting, Sichuan Province; Linzhou, Henan Province; Yangzhong, Jiangsu Province; and Feicheng, Shandong Province) from 2005 to 2019. Genomic DNA was extracted from paraffin biopsy samples and paired peripheral white blood cells from patients, and a quantitative polymerase chain reaction assay, P16-Light, was used to detect CDKN2A copy number. The cumulative regression and progression rates of ESCdys were evaluated using competing risk models. Results::A total of 205 patients with baseline m/M ESCdys were enrolled. The proportion of ESCdys regression was significantly lower in the CDKN2A deletion cohort than in the diploid and amplification cohorts (18.8% [13/69] vs. 35.0% [28/80] vs. 51.8% [29/56], P <0.001). In the univariable competing risk analysis, the cumulative regression rate was statistically significantly lower ( P = 0.008), while the cumulative progression rate was higher ( P = 0.017) in ESCdys patients with CDKN2A deletion than in those without CDKN2A deletion. CDKN2A deletion was also an independent predictor of prognosis in ESCdys ( P = 0.004) in the multivariable analysis. Conclusion::The results indicated that CDKN2A SCNVs are associated with the prognosis of ESCdys and may serve as potential biomarkers for risk stratification.

[Purpose]To investigate the trends of incidence and age at onset of uterine corpus can-cer in Jiangsu cancer registration areas from 2009 to 2019.[Methods]The continuous monitoring data of uterine corpus cancer from 2009 to 2019 were collected from 16 cancer registries in Jiang-su Province.The crude incidence rate,the age-standardized incidence rate by Chinese standard population(ASIRC),crude and adjusted mean age,and standardized age-specific incidence composition were calculated.The average annual percentage change(AAPC)were analyzed by the Joinpoint regression model.The linear regression model was used to analyze the relationship be-tween mean age at onset and year.The standardized age-specific incidence composition in 2009 and 2019 were compared.[Results]The ASIRC of uterine corpus cancer in all registration areas and in rural areas of Jiangsu Province showed upward trends with AAPC of 1.78％and 2.38％,re-spectively(P＜0.05),but not showed in the urban areas(AAPC=1.30％,P＞0.05).The crude mean age at onset increased from 56.48 years old in 2009 to 58.26 years old in 2019 with an average annual growth of 0.173 years old(P=0.001).After the population structure standardized,the trends disappeared in all registration areas.[Conclusion]From 2009 to 2019,the standardized incidence rates of uterine corpus cancer were on rise in Jiangsu cancer registration areas,especially in the age group of 50 to 59 years old.

Objective: To investigate the trends in the disease burden of leukemia in Jiangsu Province from 1990 to 2019, so as to provide insights into leukemia control in Jiangsu Province. Methods: The prevalence, incidence, death and disability adjusted life years (DALYs) of leukemia in Jiangsu Province from 1990 to 2019 were retrieved from the 2019 Global Burden of Disease Study (GBD 2019) database, and standardized by the age structure of Chinese populations in 2000. The trends in the disease burden of leukemia in Jiangsu Province from 1990 to 2019 were analyzed using average annual percent change (AAPC). Results : The average annual standardized prevalence, incidence, mortality and DALY rate of leukemia were 63.63/105, 9.76/105, 4.10/105 and 194.83/105 in Jiangsu Province from 1990 to 2019, respectively. The average annual standardized prevalence (AAPC=1.420%, t=5.644, P<0.001) and incidence (AAPC=0.806%, t=3.505, P<0.001) of leukemia appeared a tendency towards a rise, while the average annual standardized mortality (AAPC=-1.589%, t=-14.714, P<0.001) and DALY rate (AAPC=-1.849%, t=-9.046, P<0.001) of leukemia appeared a tendency towards a decline in Jiangsu Province from 1990 to 2019. Higher average annual standardized prevalence (65.27/105 vs. 62.38/105, P<0.001), incidence (10.32/105 vs. 9.29/105, P<0.001), mortality (4.69/105 vs. 3.57/105, P<0.001) and DALY rate of leukemia (216.94/105 vs. 172.80/105, P<0.001) were estimated among men than among women. The crude prevalence of leukemia peaked among patients at ages of 0 to 14 years and 60 to 74 years, and the crude incidence, DALY rate and mortality of leukemia peaked at ages of 0 to 14 years and 75 years and older. Conclusions The mortality and DALY of leukemia appeared a tendency towards a decline and the prevalence and incidence appeared a tendency towards a rise in Jiangsu Province from 1990 to 2019; however, there were high disease burdens of leukemia among men, children and the elderly.

Objective:To optimize the different salt preparation processes of salt-processed Psoraleae Fructus and compare the differences among different salt products.Methods:Ultra-high performance liquid chromatography (UPLC) characteristic chromatogram of Psoraleae Fructus was established. By using the comprehensive scoring method, the total content of psoralen and isopsoralen and the peak area of the characteristic chromatogram were used as the evaluation index to optimize the four different processing technologies, including "stir-frying with salt-water", "steaming with salt-water", "spraying with salt-water" and "microwaving with salt-water". Meanwhile, entropy weight TOPSIS method, clustering analysis (HCA), principal component analysis (PCA) and other chemical pattern recognition methods were used to compare the quality difference of different salt-processed Psoraleae Fructus.Results:The optimized "stir-frying with salt-water" process of salt-processed Psoralea Fructus was 170 ℃ for 13 min, "steaming with salt-water" process for 1 h, "spraying with salt-water" process for 110 ℃ for 13 min and "microwaving with salt-water" process for 105 s microwave heating. TOPSIS comprehensive evaluation results of entropy weight showed that the quality of different salt products of Psoraleae Fructus ranked as product of stir-frying with salt-water > product of stir-frying with green salt-water > product of spraying with salt-water > product of microwaving with salt-water > product of steaming with salt-water; HCA results showed that different salt products of Psoraleae Fructus could be polymerized into two categories, between which product of stir-frying with salt-water and product of stir-frying with green salt-water were polymerized into one category; product of spraying with salt-water, product of microwaving with salt-water and product of steaming with salt-water were another category; the results of PCA showed that different salt products of Psoraleae Fructus could be clustered into 4 categories, among which product of stir-frying with salt-water, product of stir-frying with green salt-water and product of spraying with salt-water were clustered into the same category respectively, and product of microwaving with salt-water and product of steaming with salt-water were clustered into the same category.Conclusion:The chemical composition of Psoraleae Fructus processed by different salting methods is different. The results of this study can provide reference for processing optimization of salt-processed Psoraleae Fructus and identification of different salt products.

Objective:To investigate the expression of Macrophage migration-inhibitory factors (MIF) in hepatocellular carcinoma (HCC) tissues and its interaction with ERK1/2 signaling pathway, so as to establish a theoretical basis for further studying the molecular mechanism of MIF promoting HCC.Methods:From February 2020 to August 2021, 52 cases of hepatocellular carcinoma (HCC) tissues based on hepatitis B cirrhosis (HBV-LC) and 52 cases of adjacent tissues in Tianjin Medical University Cancer Hospital and 940th Hospital of Joint Logistic Support Force of PLA were collected as the experimental group, including 39 males and 13 females, aged 35-65 years. And 20 cases of normal liver tissue were selected as the control group. Immunohistochemistry was used to detect the expression of MIF, ERK1/2 and p-ERK1/2 proteins in liver tissues of the two groups, and in situ hybridization was used to detect the expression of ERK1/2 nucleic acid in liver tissues of the two groups.HepG2 HCC cells and L-02 normal hepatocytes were co-cultured with different concentrations of rMIF, the expression and phosphorylation levels of ERK1/2 and JNK1 proteins in the two kinds of liver cells were detected by Western-blot, and the expression levels of ERK1/2 nucleic acids in the two kinds of liver cells were detected by RT-PCR. One-way ANOVA was used for measurement data and χ 2 test was used for counting data. Results:The expressions of MIF, ERK1/2, p-ERK1/2 and ERK1/2 mRNA were significantly increased in HCC and para-cancer tissues (the expression of MIF in HCC group was 78.8%, and that in adjacent group was 75.0%; ERK1/2 80.8% in HCC group and ERK1/2 71.8% in paracancerous group. The expression of p-ERK1/2 75.0 % in HCC group and 46.2% in paracancerous group were respectively detected. ERK1/2 mRNA was expressed in HCC group 76.9%, ERK1/2 mRNA expression in paracancerous group 78.8%), and the differences were statistically significant compared with normal liver tissues ( P<0.05), but there was no significant difference between HCC and para-cancer tissues ( P>0.05). The expressions of ERK1/2, p-ERK1/2 and ERK1/2 mRNA in HepG2 HCC cells were significantly increased with the increase of rMIF concentration, and the increase was most obvious when rMIF concentration was 200 ng/ml, and the difference was statistically significant compared with L-02 normal hepatocytes ( P<0.05). Conclusion:MIF, ERK1/2 and p-ERK1/2 are highly expressed in HCC tissues and HepG2 HCC cells, suggesting that MIF promotes the occurrence and development of hepatocellular carcinoma through ERK1/2 signaling pathway.

Methods: The stroke morbidity data in Lianyungang City from 2014 to 2020 were captured from Lianyungang Municipal System for Monitoring of Cardiovascular and Cerebrovascular Diseases, and standardized by the sixth national population census data in China in 2010. The trends in stroke incidence were evaluated using average annual percentage change (AAPC), and the gender-, age-, region- and disease type-specific incidence and trends in incidence of stroke were descriptively analyzed. Results: Totally 162 423 new stroke cases were diagnosed in Lianyungang City from 2014 to 2020 new case, and the annual mean crude and standardized incidence rates were 435.32/105 and 357.28/105, which both appeared a tendency towards a rise (AAPC=12.61%, t=39.098, P<0.001; AAPC=9.91%, t=6.123, P<0.001) . The standardized incidence of stroke was significantly higher in men than in women (389.63/105 vs. 327.17/105; χ2=4.056, P=0.044). The crude incidence of stroke appeared a tendency towards a rise with age among residents (χ2trend=258.219, P<0.001), and appeared a tendency towards a rise among residents at ages of <35 (AAPC=22.52%, t=6.723, P<0.001), 35 to 64 (AAPC=9.78%, t=7.867, P<0.001) and 65 years and older (AAPC=10.24%, t=5.156, P<0.001). The crude incidence was higher in rural areas than in urban areas (437.72/105 vs. 425.31/105; χ2=20.709, P<0.001). Ischemic stroke was the predominant type (139 680 cases, 86.00% of all cases), and both the crude and standardized incidence appeared a tendency towards a rise (AAPC=13.79%, t=16.865, P<0.001; AAPC=10.88%, t=5.128, P<0.001). Conclusion The incidence of stroke appeared a tendency towards a rise among residents living in Lianyungang City from 2014 to 2020. Men, middle-age and elderly residents and rural residents are high-risk populations for stroke control.

Objective:To observe the efficacy of Long’s bone setting manipulation combined with hyperbaric oxygen（HBO）in the treatment of vertigo caused by cervical spondylosis of the vertebral artery type（CSA）.Methods:A total of 143 patients with CSA and vertigo treated in the Department of Rehabilitation Medicine of the Second Hospital of Shanxi Medical University from April 2019 to July 2020 were prospectively included as the research subjects by a random number table. The patients were divided into control group（72 cases）and observation group（71 cases）. The control group was treated with Long’s bone setting manipulation，while the observation group was treated with Long’s bone setting manipulation combined with HBO. The overall curative effect of the two groups was evaluated and compared by Traditional Chinese Medicine Syndrome Score Scale（TCMSSS）. The vertigo symptom of the two groups was evaluated by Dizziness Handicap Inventory（DHI）. The hemodynamic indexes of vertebral artery，including left vertebral artery（LVA），right vertebral artery（RVA）and basilar artery（BA），were detected and compared between the two groups by Doppler ultrasound.Results:After treatment，the overall curative effect of the observation group was better than that of the control group，with statistically significant difference（ P < 0.05）. No statistically significant difference in DHI scores or vertebral artery hemodynamic indexes between the two groups was observed before treatment（ P > 0.05）. After treatment，the observation group had lower DHI scores while higher indexes of LVA，RVA and BA compared with those in the control group（ P < 0.05）. Conclusion:Long’s bone setting manipulation combined with HBO has better efficacy than Long’s bone setting manipulation alone in the treatment of vertigo caused by CSA，which is more conducive to reducing vertigo symptoms and improving vertebral artery hemodynamics.

Objective:To establish a nomograph prediction model of early critical changes in children with febrile convulsion, and to provide guidance for the prevention and nursing of children with febrile convulsion.Methods:Convenient sampling method was adopted to select 384 children with febrile convulsion in Anhui Children ′s Hospital from January 2018 to April 2021 as the research objects. Based on pews, the children with febrile convulsion were divided into 334 cases of non risk group and 50 cases of risk group. Binary Logistic regression analysis were used to determine the independent risk factors affecting the early critical changes of children with febrile convulsion. A nomogram was drawn based on the independent risk factors. The discrimination and consistency of the model were verified by model ROC curve and Hosmer Lemeshow goodness of fit.The external validation of model prediction efficiency were verified by validation data. Results:Binary Logistic regression analysis showed that age, respiratory rhythm disorder, unconsciousness, breath rate, heart rate, neutrophil-to-lymphocyte ratio (NLR), red blood cell distribution width (RDW), duration of first convulsion and mean body temperature after first convulsion were influence factors for early critical changes in children with febrile convulsion ( P<0.05). The C-index of the model was 0.974 (95% CI 0.954-0.993), and the C-index of the external validation of the model was 0.922 (95% CI 0.880-0.966). The results of H-L fitting test showed that the difference was not statistically significant( χ2=0.29, P>0.05). Conclusions:The early critical changes of children with febrile convulsion may be affected by respiratory rhythm disorder, confusion of consciousness, breath rate, heart rate, NLR, RDW, duration of the first convulsion, mean temperature after the first convulsion and other factors. Pediatric emergency department should collect corresponding intervention measures for children with febrile convulsion according to the establishment of prediction model to prevent their early deterioration.
