[Purpose]To analyze the changing trends of the disease burden of liver cancer related to hepatitis B virus(HBV)globally and in China from 1992 to 2021.[Methods]Based on the Global Burden of Disease database in 2021,indicators such as the age-standardized incidence rate and mortality rate of HBV-related liver cancer globally and in China from 1992 to 2021 were collected.The Joinpoint regression model was used to analyze the changing trends of epidemiologi-cal characteristics,and the age-period-cohort model was adopted to analyze the impacts of age,period,and cohort factors on the incidence and mortality risks of HBV-related liver cancer globally and in China.[Results]From 1992 to 2021,the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer globally generally showed a trend of decreasing.The average annual percentage changes were-0.31％and-0.61％,respectively,and all the down-ward trends were statistically significant(both P＜0.05).During the same period,the average annu-al percentage changes of the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer in China were-0.45％and-0.90％,respectively,and all the downward trends were statistically significant(both P＜0.05).The results of the age-period-cohort model anal-ysis showed that from 1992 to 2021,the annual net drift rates of the incidence of HBV-related liver cancer globally and in China were-0.71％(95％CI:-0.84％～-0.57％)and-0.73％(95％CI:-1.01％～-0.44％),respectively.The annual net drift rates of the mortality were-1.15％(95％CI:-1.28％～-1.02％)and-1.42％(95％CI:-1.69％～-1.14％),respectively,all showing an over-all decline.The age effect showed that the risk of HBV-related liver cancer incidence in both the global and Chinese populations began to increase after 30 years of age,peaking in the 70～74 age group,while the risk of mortality surged after 40 years of age and peaked in the population aged 80 and above.The period effect indicated that the incidence and mortality risks were the highest from 1997 to 2001 and the lowest from 2017 to 2021.The cohort effect revealed that the inci-dence and mortality risks gradually decreased in populations born after 1962,with the 2007-2011 birth cohort having the lowest risks.The results of the Wald x2 test showed that there were statistically significant differences in the changing trends of the age,period,and cohort effects on the incidence and mortality of HBV-related liver cancer globally and in China(all P＜0.05).[Con-clusion]From 1992 to 2021,the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer showed a downward trend both globally and in China.The disease burden of HBV-related liver cancer in China was higher than the global level.The age-period-cohort model has revealed the historical changes in the incidence and mortality of HBV-related liver cancer.The current and future situation of the disease burden of HBV-related liver cancer is not optimistic.It is recommended to implement precise stratified interventions for populations of different ages,periods,and birth cohorts,and actively transform the prevention,treatment,and management strategies for HBV-related liver cancer.

[Purpose]To analyze the incidence,mortality and trends of bladder cancer worldwide and in China in 2022.[Methods]The incidence and mortality data of bladder cancer were ob-tained from the GLOBOCAN 2022 database by geographical regions,sex,age,and human deve-lopment index(HDI).The crude incidence/mortality rate,age-standardized incidence/mortality rate(ASIR/ASMR)of bladder cancer were calculated.Simple linear regression and Spearman's correla-tion test were used to analyze the correlation between the HDI and ASIR/ASMR,the trends of in-cidence and projection in 2050 were estimated.[Results]In 2022,the estimated numbers of new cases and deaths of bladder cancer worldwide were 614 298 and 220 596,respectively,with ASIR and ASMR of 5.6/105 and 1.8/105.ASIR and ASMR in Europe were the highest,with 12.0/105 and 3.0/105,respectively.The ASIR and ASMR for males were higher than those for females,and increased rapidly after 40 years old of age.A positive correlation was observed between HDI levels and ASIR and ASMR of bladder cancer(r=0.670 and 0.434,respectively,both P＜0.001).It was projected that the global incidence and mortality of bladder cancer would reach 1.229 million and 0.494 million by 2050,and 0.176 million and 0.103 million for China,respectively.[Conclusion]The incidence and mortality of bladder cancer varies significantly among different region,sex,age and HDI levels worldwide.With the population aging and the industrialization accelerating,the risk of bladder cancer in China has been increasing.The prevention and control efforts for bladder cancer should be further strengthened.

Objective:To investigate the predictive values of baseline hematoma mean CT value and shape regularity (SR) for hematoma enlargement (HE) in patients with spontaneous intracerebral hemorrhage (ICH).Methods:Patients with ICH admitted to Yulin First Hospital from June 2018 to December 2021 were retrospectively included. The first head CT scan was performed within 24 h of onset, and the second head CT scan was performed within 72 h of the first scan. HE was defined as an increase in hematoma volume of at least 6 ml or 33% from the first CT. 3D Slicer software was used to reconstruct 3D images and SR was calculated. Multivariate logistic regression analysis was used to determine the independent factor for HE. Receiver operator characteristic (ROC) curve was used to evaluate the predictive value of baseline hematoma mean CT value for HE. Results:A total of 249 patients with ICH were enrolled, including 134 males (53.8%), and aged 62.2±12.1 years. The median baseline Glasgow Coma Scale score was 12, and the median time from onset to first CT scan was 3.1 h. The median baseline hematoma volume was 10.9 ml, and 58 patients (23.3%) showed HE. The baseline hematoma mean CT value in the HE group (58.5±3.2 HU vs. 60.3±3.3 HU; P<0.01) and baseline SR (0.615±0.146 vs. 0.688±0.100; P<0.001) were significantly lower in the non-HE group. Multivariate logistic regression analysis showed that the time from onset to first CT scan (odds ratio [ OR] 0.867, 95% confidence interval [ CI] 0.786-0.957; P=0.004), the baseline hematoma volume ( OR 1.050, 95% CI 1.028-1.073; P<0.001), and the baseline hematoma mean CT value ( OR 0.809, 95% CI 0.725-0.902; P<0.001) were the independent predictors of HE, while the baseline SR had no significant independent correlation with HE. ROC curve analysis showed that the area under the curve of baseline hematoma mean CT value for predicting HE was 0.652 (95% CI 0.573-0.731; P<0.001), with an optimal cutoff value of 57.97 HU. The sensitivity and specificity for predicting HE were 50% and 75.9%, respectively. Conclusion:The baseline hematoma mean CT value is an independent factor for HE in patients with ICH and has certain predictive value for HE.

Objective To demonstrate the changes in flexor digitorum and extensor digitorum tension in the affected hands with shear-wave elastography (SWE) before and after manual digitorum sensory stimulation (MDSS) in hemiplegic patients with stroke. Methods A total of 51 hemiplegic post-stroke inpatients in the Department of Rehabilitation Medicine in Second Hospital of Anhui Medical University from April to June, 2020, underwent MDSS completed by a researcher who used a bare thumb and index finger to squeeze each nail bed as well as the sides of each fingertip in the affected hand. The stimulation intensity was the minimum that could cause finger extension without obvious pain, and the interval between two stimulations was five to ten seconds. Muscular tension of the flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus and extensor digitorum were assessed with modified Ashworth Scale (MAS) and shear-wave velocity (SWV) of SWE on the affected side before and immediately after MDSS. MAS score was -1 as low muscular tension. Results The MAS scores of all the muscles significantly reduced after MDSS (|Z| > 2.843, P < 0.001); while the changes of SWV were not significantly in all the muscles with initially MAS score of 0 or -1 (t < 1.052, P > 0.05), and it reduced in those muscles with initial MAS scores of one to three (t > 2.672, P < 0.05). The SWV were positively correlated with the MAS scores both before and after MDSS (r > 0.334, P < 0.05). Conclusion MDSS can effectively, immediately, and safely relieves muscle spasms of the flexor digitorum and facilitate active finger extension in the affected hand for hemiplegic patients with stroke. SWE is useful for quantitatively and objectively evaluating muscular tension in the affected hand for hemiplegic patients with stroke.

AIM To speculate the hypoglycemic mechanism for rats with type 2 diabetes by exploring the therapeutic effects of leaf aqueous extract from Cyclocarya paliurus on liver insulin receptor (InsR) and insulin receptor substrate 2 (IRS-2).METHODS The diabetic rat model was established through intraperitoneal injection of streptozotocin and fed with high-fat diet.The moleled rats were equally assigned into the control group and leaf aqueous extract from Cyclocarya paliurus group (extract group).After the test extract was orally administrated for four weeks,body weight,urine output,food intake,water intake and fasting blood-glucose (FBG) were measured,and the levels of serum insulin,InsR and IRS-2 mRNA in liver tissue were investigated in rats.RESULTS Compared with the control group,the extract group showed a reduction in urine output,food intake,water intake,FBG and insulin levels.Meanwhile,the rats' body weights in extract group were presented a trend to increase.The gene expressions of InsR and IRS-2 in liver tissue were up-regulated.Moreover,the insulin sensitivity was improved.CONCLUSION The leaf aqueous extract from Cyclocarya paliurus can reduce FBS,improve insulin sensitivity,which may be associated with the increase of InsR and IRS-2 gene expression in liver tissue.
