Objective: To investigate the trends in incidence and mortality of esophageal cancer in cancer registration areas of Anhui Province from 2014 to 2020, so as to provide the basis for formulating prevention and control measures. Methods: The incidence and mortality data of esophageal cancer in Anhui Province from 2014 to 2020 was collected through the Cancer Registry in Anhui Province. The crude incidence and crude mortality were calculated. The Chinese population-standardized rate was standardized using the age structure of the standard population from the Fifth National Population Census in 2000. The trends in incidence and mortality of esophageal cancer were analyzed using the average annual percent change (APPC), stratified by genders, urban/rural areas, and ages. Results: In Anhui Province, the rank of esophageal cancer incidence dropped from the third in 2014 to the sixth in 2020. Concurrently, the crude incidence and Chinese population-standardized incidence declined from 28.74/100 000 and 20.74/100 000 to 19.23/100 000 and 10.59/100 000, respectively (AAPC=-5.846%, -9.658%, both P<0.05). The mortality rank remained stable at the fourth in 2014 and 2020, while the crude mortality and Chinese population-standardized mortality decreased from 19.96/100 000 and 14.09/100 000 to 16.00/100 000 and 8.41/100 000, respectively (AAPC=-3.542%, -7.784%, both P<0.05). The Chinese population-standardized incidence (AAPC=-9.682%, -9.188%, -6.175% and -12.575%, all P<0.05) and Chinese population-standardized mortality (AAPC=-7.734%. -7.447%. -5.366% and -10.209%, all P<0.05) showed declining trends in males, females, urban, and rural areas, respectively. From 2014 to 2020 in Anhui Province, the crude incidence and mortality of esophageal cancer generally increased with age. However, significant declining trends were observed in crude incidence (AAPC=-12.779%, -11.701%, -11.955% and -5.751%, all P<0.05) and crude mortality (AAPC=-12.255%, -11.120%, -10.985% and -5.751%, all P<0.05) for the age groups of 40-<50, 50-<60, 60-<70, 70-<80 years. A significant declining trend in crude incidence was also seen in the ≥80 years group (APPC=-6.334%, P<0.05), but the trend in crude mortality was no statistically significant (P>0.05). Conclusion In registration areas of Anhui Province, the incidence and mortality of esophageal cancer exhibited a declining trend from 2014 to 2020, calling for focused attention on the middle-aged and elderly population and enhanced health behaviors such as tobacco and alcohol control.

Objective:To explore the independent association between handgrip strength and chronic kidney disease (CKD) in adult residents in Anhui Province using data from the China Adult Chronic Disease and Risk Factor Surveillance (2023).Methods:A multi-stage stratified cluster random sampling method was used to select residents aged ≥18 years for surveys, physical measurements, and laboratory tests. Relevant covariates were adjusted, and a multivariable logistic regression model was established to infer the association between handgrip strength and CKD, followed by subgroup analysis.Results:A total of 7 295 participants were included in the study, with age of (61.5±13.2) years, and 55.6% of the study participants were women. The results of the multivariate logistic regression analysis showed that with each 1.0 kg increase in handgrip strength, the risk for CKD decreased by 1.3% ( OR=0.987, 95% CI: 0.978-0.997). Compared with those with low handgrip strength, the people with moderate hasdgrip strength ( OR=0.818, 95% CI: 0.694-0.964) and high handgrip strength ( OR=0.729, 95% CI: 0.598-0.989) had lower risk for CKD. In the subgroup analysis, the association between handgrip strength and risk for CKD remained unchanged regardless age, sex, smoking status, and alcohol consumption statuys, and the prevalence of hypertension and hyperlipidemia (interaction P>0.05), except BMI and diabetes. Conclusion:The decline in handgrip strength is associated with an increased risk for CKD in adult residents in Anhui.

Objective To analyze histopathological and clinical features of dermatofibroma,and to explore the relationship between them.Methods Clinical and histopathological data were collected from 150 patients with histopathologically confirmed dermatofibroma in Department of Pathology,Shanghai Skin Disease Hospital from September 2017 to August 2018,and analyzed retrospectively.Results Among the 150 patients,65 were males,and 85 were females.Their age was 42 ± 13.8 years,and the course of disease ranged from 3 months to 30 years.Some of the patients had concomitant symptoms,mainly manifesting as itching,some had spontaneous pain and mild tenderness,and 18 patients had a history of injury,insect bite or infection at lesion sites.Skin lesions mainly occurred on the extremities (107 cases,71.3％),and most were solitary (105 cases,70％).Before pathological examinations,102 cases were clinically diagnosed as dermatofibroma,16 as epidermoid cyst,13 as pigmented nevus,3 as keloid,12 as skin mass,1 as malignant melanoma,1 as xanthogranuloma,1 as prurigo nodularis,and 1 as neurofibroma.Among 169 hematoxylin and eosin (HE)-stained sections,25 (14.8％) appeared to be consistent with aneurysmal dermatofibroma,66 (39.1％)with cellular dermatofibroma,36 (21.3％) with sclerosing dermatofibroma,and 22 (13.0％)with epithelioid dermatofibroma.Coexistence of two or more subtypes could be seen in 12 sections.There were also a few new variants,such as dermatofibroma with hyperplastic sweat duct (1 case),deep dermatofibroma (3 cases),dermatofibroma with epithelioid cells intermingled with hyperplastic collagen (1 case).The duration of aneurysmal dermatofibroma varied from 7 months to 30 years,and most manifested as skin masses on the lower extremities.A relatively short course of disease was observed in patients with cellular dermatofibroma,who often visited a hospital several months after the onset,and cellular dermatofibroma was commonly observed on the extremities and frequently accompanied with itching and pain.The duration of sclerosing or atrophic dermatofibroma was usually long for years or decades,and it commonly occurred on the upper limbs without concomitant symptoms.Epithelioid dermatofibroma of varied durations had various clinical manifestations,frequently occurred on the lower limbs without concomitant symptoms.Conclusions The clinical and pathological manifestations of dermatofibroma are diverse.Different dermatofibroma lesions can share similar typical histopathological manifestations,and atypical pathological features can interfere with the diagnosis of dermatofibroma.

Alpha-glycerophosphate oxidase (alpha-GPO) from Enterococcus casseli flavus was successfully isolated and purified by using polyethylene glycol (PEG)/(NH4)2SO4 aqueous two-phase system (ATPS). The results showed that the chosen PEG/(NH4)2SO4 ATPS could be affected by PEG molecular weight, pH, concentration of PEG and (NH4)2SO4, and inorganic salt as well as additional amount of crude enzyme. After evaluating these influencing factors, the final optimum purification strategy was formed by 16.5% (m/m) PEG2000, 13.2% (m/m) (NH4)2SO4, pH 7.5 and 30% (m/m) additive crude enzyme, respectively. The NaCl was a negative influencing factor which would lead to lower purification fold and activity recovery. These conditions eventually resulted in the activity recovery of 89% (m/m), distribution coefficient of 1.2 and purification fold of 7.0.
