ABSTRACT
BackgroundDepression presents a significant risk to the physical and mental health of the elderly. The relationship between sleep and depressive symptoms has become a major research focus. However， previous research findings on this relationship have yielded inconsistent conclusions. ObjectiveTo explore the relationship between sleep duration and depressive symptoms in the elderly， in order to provide insights into the prevention of depressive symptoms and delaying their progression in the elderly. MethodsData analysis involved 8 210 adults aged 60 years or older， utilizing data from the 2018 China Health and Retirement Longitudinal Study （CHARLS） survey. Participants were categorized into two groups those with depressive symptoms and those without- based on the Center for Epidemiologic Studies Depression-10 Scale （CESD-10） criteria. Logistic regression and restricted cubic spline models were used to analyze the association between sleep duration and depressive symptoms. ResultsThe 318 people with depressive symptoms were detected among the 8 210 elderly participants， with an average sleep duration of （6.14±2.05） hours per night. Restricted cubic spline models showed a non-linear association between sleep duration and depressive symptoms （χ2=412.670，P<0.01）. After adjusting for confounding factors， compared to the elderly with a sleep duration 7~7.9 hours， the risk of depressive symptoms in the elderly was 2.971 times higher （95% CI： 2.560~3.449， P<0.01） in those with a sleep duration <6 hours， 1.372 times higher （95% CI： 1.161~1.621， P<0.01） in those with 6~6.9 hours， and 1 185 times higher （95% CI： 1.009~1.393， P<0.05） in those with ≥8 hours. Subgroup analysis showed no correlation between sleep duration ≥8 hours and the risk of depressive symptoms across genders and the 60~69 age group （P>0.05）. ConclusionThere was an approximately nonlinear association between sleep duration and depressive symptoms， with differences by gender and age.［Funded by Sichuan Applied Psychology Research Center， Chengdu Medical College （number， CSXL-22226）］
ABSTRACT
Background@#This study investigated the effect of short-chain fatty acids (SCFAs) on diabetes in a mouse model. @*Methods@#Autophagy in Akita mice and streptozocin (STZ)-induced diabetic C57BL/6 mice was determined by Western blots and immunohistochemistry (IHC). Western blots, IHC, hematoxylin and eosin staining, Masson staining, periodic acid-Schiff staining, and picrosirius red staining were conducted to detect whether autophagy and renal function improved in Akita mice and STZ-induced diabetic C57BL/6 mice after treatment of SCFAs. Western blots, IHC, and chromatin immunoprecipitation were performed to determine whether SCFAs affected diabetic mice via the histone deacetylase (HDAC2)/unc-51 like autophagy activating kinase 1 (ULK1) axis. Diabetic mice with kidney-specific knockout of HDAC2 were constructed, and IHC, Masson staining, and Western blots were carried out to detect whether the deletion of endogenous HDAC2 contributed to the improvement of autophagy and renal fibrosis in diabetic mice. @*Results@#Reduced autophagy and severe fibrosis were observed in Akita mice and STZ-induced diabetic C57BL/6 mice. Increased autophagy and reduced renal cell fibrosis were found in SCFA-treated Akita diabetic mice and STZ-induced diabetic C57BL/6 mice. Diabetic mice treated with SCFAs had lower HDAC2 expression and more enriched binding of ULK1 promoter sequences to H3K27Ac. Endogenous knockout of HDAC2 caused enhanced autophagy and decreased renal fibrosis in diabetic mice treated with SCFAs. @*Conclusion@#SCFAs enhanced autophagy of renal tubular cells and attenuated renal fibrosis in diabetic mice through the HDAC2/ULK1 axis.
ABSTRACT
Since the Global Polio Eradication Initiative was launched by the World Health Assembly in 1988, significant progress has been made in global polio prevention and control. But the occurrence of vaccine-associated paralytic poliomyelitis cases and vaccine-derived poliovirus related cases have become a major challenge during the post-polio era. While coronavirus disease 2019(COVID-19) has brought serious disease burden and economic burden to all countries in the world, prevention and control of vaccine-preventable infectious diseases such as polio should not be neglected under the background of the global common fight against COVID-19. Taking the type Ⅲ VDPV cycle event in Shanghai as an example, the paper discussed how to do a good job of routine inoculation under the prevention and control of COVID-19 to strictly prevent the outbreak of vaccine-preventable infectious diseases.

ABSTRACT
Objective@#To identify the etiology and source of infection in a diarrhea outbreak in Yunnan in May 2017 and to provide the evidence for formulating prevention and control measures.@*Methods@#Epidemiological investigation was carried out on the epidemic situation of diarrhea in the village of Lvchun County in Yunnan Province, the field sampling, laboratory testing and data analysis were also performed.@*Results@#Among the 44 patients, 11 of the 13 samples were positive for rotavirus nucleic acid in group A, and the positive rate was 84.62%. The survey showed that the water supply pipe was damaged and polluted by human and livestock manure and domestic sewage. The trend of the damaged water pipe was basically the same as the case distribution, and the rainfall was significantly related to the number of the disease.@*Conclusions@#This event was an outbreak of diarrhea caused by group A rotavirus. The direct pollution of drinking water caused by rainfall may be the risk factor of this outbreak. The health management of rural drinking water should be strengthened and the health knowledge and education of preventing intestinal infectious diseases should be promoted.

ABSTRACT
Objective To compare the recent adverse reactions caused by 131I-Metuximab (licartin) treatment via two different routes and to assess the safety and advantages of peripheral intravenous bolus of licartin for the treatment of advanced HCC.Methods Clinical data of 54 patients (45 males,9 females,age 33-80 years) with advanced HCC treated with Licartin in Tianjin Medical University Cancer Institute and Hospital from October 2010 to March 2013 were collected and analyzed.The patients were divided into vein group (n=33) with Licartin injected through peripheral vein and artery group (n =21) with Licartin injected through hepatic artery.The results of blood routine examination,liver and kidney function and thyroid function between the two groups (1 week before treatment,4 and 12 weeks after treatment) were compared.The adverse reaction rate (ARR) and adverse reaction progression rate (ARPR) were also compared between the 2 groups.Ten days after Licartin treatment,all patients underwent gamma imaging to access the drug distribution in vivo.x2 test and two-sample t test were used to analyze data.Results There were no significant differences on age,gender and TNM staging between the vein group and the artery group (t =0.721,x2=0.561 and 4.769,all P＞0.05).The vein group showed temporary drug-related leucopenia (x2=7.041,P＜0.05) and increased level of serum total bilirubin (STB;x2 =10.297,P＜0.05) 4 weeks post-treatment.Twelve weeks later,the above parameters returned to baseline.In artery group,no influence on liver and kidney functions was observed,but the numbers of WBC and PLT decreased significantly (x2 =8.949 and 8.778,both P＜0.05) and returned to baseline 12 weeks post-treatment.The ARR in patients who had normal ALT levels before treatment between the two groups was significantly different(3.33％(1/30) vs 5/19,x2=5.718,P＜0.05).No significant difference was observed on ARR in patients with normal level of other parameters,and on ARPR in patients with abnormal preoperative parameters between the two groups (x2 =0.000-2.500,all P＞0.05).The drug's in vivo biodistribution and the thyroid function between the 2 groups showed no significant difference.Conclusion The peripheral intravenous bolus administration of Licartin is safe to treat patients with advanced HCC.
ABSTRACT
Background:Conventional gastrointestinal endoscopy is incapable of determining the deriving layers,size and nature of submucosal lesions,however,mini probe ultrasonography(MPS)is effective for mural stratification and determining the deriving layers and nature of lesions within gastrointestinal wall,and is considered to be an optimal examination for suspected submucosal tumors before endoscopic or surgical operation. Aims:To assess the diagnostic value of MPS for gastrointestinal submucosal lesions and the significance of MPS-assisted endoscopic therapy. Methods:A total of 69 patients with presumed gastrointestinal submucosal protruded lesions were retrospectively enrolled. All of them underwent MPS and then endoscopic therapy,such as cyst incision,high frequency electric snare resection,endoscopic mucosal resection and endoscopic submucosal dissection were performed according to the deriving layers,size and nature determined by MPS. The ultimate diagnosis was confirmed by histopathological examination. Results:In the 69 cases of lesions,MPS showed that 15 were derived from muscularis mucosa,40 from submucosa,and 14 from muscularis propria;10 of them were considered as cyst,18 were stromal tumor,8 were leiomyoma,6 were ectopic pancreas,15 were neuroendocrine tumor,and 12 were lipoma. Compared with pathological diagnosis,an overall coincidence rate of 91. 3%(63 / 69)was achieved by MPS. Conclusions:The accuracy rate of MPS is high for determining the deriving layers and nature of gastrointestinal submucosal protruded lesions prior to the attempting of endoscopic removal. It might be helpful for selecting treatment modalities for this kind of lesions.
