Objective To analyze the epidemiological characteristics of hepatitis A in Guangxi from 2010 to 2020, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of hepatitis A in Guangxi from 2010 to 2020. Results From 2010 to 2020, a total of 8,742 cases of hepatitis A were reported in Guangxi, with an average annual incidence rate of 1.66 /100,000. There were 5 298 male cases (60.60%), and 3,444 female cases (39.40%). The incidence rate decreased from 2.73/100 000 in 2010 to 1.38/100 000 in 2020. The onset seasonality was strong in 2010, but there was no obvious seasonality in other years. A total of 5 891 cases (67.39%) were aged from 25 to 64 years. Farmers accounted for 59.79% of the cases. A total of 7 hepatitis A outbreaks were reported during 2010-2020, including 273 cases，accounting for 3.12% of the total cases．The incidence rates of hepatitis A in Hezhou (3.97/100 000), Wuzhou (2.98/100 000), Hechi (2.44/100 000), Guigang (2.00/100 000) and Beihai (1.79/100 000) were relatively higher than other places. Conclusion The number of reported hepatitis A cases in Guangxi has been declining year by year, and the prevention and control measures of hepatitis A vaccine prevention are effective. The surveillance of hepatitis A should be strengthened, and prevention and control strategies should be formulated for high-risk areas and key populations.

Lysine acetyltransferase 5 (KAT5), a member of the MYST family, can participate in cellular processes such as transcription, DNA repair, differentiation and signal transduction by acetylating different substrates. The role of KAT5 cannot be replaced by other MYST family members, and the knockout of KAT5 can directly lead to apoptosis, indicating that KAT5 may be located in the upstream of physiological signaling pathways in cells and play an extremely important and unique role. Therefore, the changes in KAT5 expression are very likely to lead to the occurrence and development of tumors. Previous studies have found that KAT5 is downregulated in breast cancer, melanoma, and lung cancer, and is considered a tumor suppressor in these tumors. However, in recent years, studies have found that KAT5 can be either highly or lowly expressed in breast cancer, liver cancer, melanoma, prostate cancer, lung cancer and other tumors. On the premise of high KAT5 expression, KAT5 can play a tumor-promoting role. While on the premise of low KAT5 expression, KAT5 can also play as a tumor suppressor. With further decrease of KAT5 expression, its tumor suppressive effect is weakened, which may lead to the occurrence and development of tumors. In addition, KAT5 has also been found to be differentially expressed in osteosarcoma, thyroid cancer, glioblastoma, colorectal cancer and other tumors, and the differential expression of KAT5 is closely related to the proliferation, metastasis, apoptosis, drug and radiotherapy resistance of tumor cells. Therefore, KAT5 is one of the potential tumor therapeutic targets. Here, we summarize the expression of KAT5 in tumors and the tumor-suppressing or tumor-promoting signaling pathways involved in the corresponding expression in recent years, hoping to provide new inspiration and reference for tumor treatment and prognosis monitoring.

Calcium signaling plays a critical role in response to various abiotic and biotic stresses in plants. Preliminarily evidence showed that calcium signaling perceived and transduced the harmful signaling generated from continuous cropping stress in R. glutinosa. To investigate the roles of calcium signaling in continuous cropping injury formation, the key genes involved in calcium signaling transduction were identified in R. glutinosa transcriptome through bioinformatic methods. Furthermore, the calcium ion concentration in both normal and continuous cropping R. glutinosa root cells were measured by potassium pyroantimonate precipitation and calcium fluorescence method. As a result, a set of 84 calcium signaling-related genes, including 5 CaMs, 12 CBLs, 21 CDPKs, 21 CIPKs, 16 CMLs, and 9 CRKs were captured in R. glutinosa transcriptome. The analysis of expression profile in continuous cropping compared to normal growth R. glutinosa indicated that continuous cropping stress significantly increased the expression of calcium signaling-related genes in continuous cropping R. glutinosa. At the same time, the abundance levels of 12 calcium signaling-related genes quantified by qPCR further validated the high expression of calcium signaling-related genes presented in continous cropping R. glutinosa. In addition, the continuous cropping condition significantly promoted the accumulation of intracellular calcium ions in R. glutinosa based on two methods of potassium pyroantimonate precipitation and calcium fluorescence. This study verified the possible roles of calcium signaling in the formation of continuous cropping injury on molecular and cellular level, which lays a solid foundation for illuminating formation mechanism of continuous cropping injury on molecular level.

BACKGROUNDUrine output (UO) is an essential criterion of the Kidney Disease Improving Global Outcomes (KDIGO) definition and classification system for acute kidney injury (AKI), of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria (KDIGOUO) could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria (KDIGOSCr).

METHODSWe conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a 2-month prospective cohort study (July 1, 2009 to August 31, 2009) involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China. AKI was diagnosed and classified separately based on KDIGOUOand KDIGOSCr. Hospital mortality of patients with more severe AKI classification based on KDIGOUOwas compared with other patients by univariate and multivariate regression analyses.

RESULTSThe prevalence of AKI increased from 52.4% based on KDIGOSCrto 55.4% based on KDIGOSCrcombined with KDIGOUO. KDIGOUOalso resulted in an upgrade of AKI classification in 7.3% of patients, representing those with more severe AKI classification based on KDIGOUO. Compared with non-AKI patients or those with maximum AKI classification by KDIGOSCr, those with maximum AKI classification by KDIGOUOhad a significantly higher hospital mortality of 58.4% (odds ratio [OR]: 7.580, 95% confidence interval [CI]: 4.141-13.873, P< 0.001). In a multivariate logistic regression analysis, AKI based on KDIGOUO (OR: 2.891, 95% CI: 1.964-4.254, P< 0.001), but not based on KDIGOSCr (OR: 1.322, 95% CI: 0.902-1.939, P = 0.152), was an independent risk factor for hospital mortality.

CONCLUSIONUO was a criterion with additional value beyond creatinine criterion for AKI diagnosis and classification, which can help identify a group of patients with high risk of death.

Recently, suppressor of cytokine signaling-3 (SOCS3) has been shown to be an inducible endogenous negative regulator of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway which is relevant in inflammatory response, while its functions in acute liver failure and HBV-induced acute-on-chronic liver failure (HBV-ACLF) have not been fully elucidated. In this study, we explored the role of SOCS3 in the development of mouse hepatitis virus strain 3 (MHV-3)-induced acute liver failure and its expression in liver and peripheral blood mononuclear cells (PBMCs) of patients with HBV-ACLF. Inflammation-related gene expression was detected by real-time PCR, immunohistochemistry and Western blotting. The correlation between SOCS3 level and liver injury was studied. Our results showed that the SOCS3 expression was significantly elevated in both the liver tissue and PBMCs from patients with HBV-ACLF compared to mild chronic hepatitis B (CHB). Moreover, a time course study showed that SOCS3 level was increased remarkably in the liver of BALB/cJ mice at 72 h post-infection. Pro-inflammatory cytokines, interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α, were also increased significantly at 72 h post-infection. There was a close correlation between hepatic SOCS3 level and IL-6, and the severity of liver injury defined by alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, respectively. These data suggested that SOCS3 may play a pivotal role in the pathogenesis of MHV-3-induced acute liver failure and HBV-ACLF.

BACKGROUNDThe Red Cross of China and Ministry of Health jointly started a pilot program of organ donation after cardiac death to overcome the shortage of available organs since 2010. The purpose of this qualitative study were to compare the consent rate of organ donation between young donor families and adult donor families; to explore and determine factors associated with differences in willingness to donate organs between them. Research objective was to provide a rationale for further preparation of professionals involved in this sensitive work.

METHODSBetween March 2010 and June 2012, 24 young deceased patients including donors and non-donors and 96 potential adult donors were collected, and consent rates of young donors' families and adult donors' families were calculated. A χ(2) test analysis to compare the consent rates of the two groups was conducted. We studied through semistructured interviews 15 parents of young donors and 15 relatives of old donors who were interviewed for petition of consent. Data collection and analysis of the overall study were performed according to the grounded theory methodology. Factors that influenced the families' decisions were identified and classified. We found the differences in willingness to donate organs between the two groups.

RESULTSThe consent rate of young donor families was 66.67%, while the consent rate of adult donor families was 26.04%. Young donor families easily consented to organ donation than adult donor families (P < 0.005). The donors' families had been affected by various factors throughout the process of deciding to give consent for donation. The findings led to the formulation of an empirically based model of interlinking categories that influence families' decision-making process in organ donation. These factors are grouped into five main categories: (1) personal factors, (2) conditions of organ request, (3) interpersonal factors, (4) ethical factors, and (5) traditional views. The funeral tradition influenced the young donor parents' consent to donation, but had no relation with family decision of adult donors. And the family members of young donors are relatively less, who are more likely to reach a consensus.

CONCLUSIONSYoung donor families influenced by traditional funeral beliefs are easier to consent to organ donation than adult donor families. Family members of young donors are relatively less who are more likely to reach a consensus. Acceptance of the expanded criteria donors may improve the organ donation rates, especially those of the advanced age.

BACKGROUNDAcute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide. However, epidemiologic data concerning AKI in China are still lacking. The objectives of this study were to characterize AKI defined by RIFLE criteria, assess the association with hospital mortality, and evaluate the impact of AKI in the context of other risk factors.

METHODSThis prospective multicenter observational study enrolled 3,063 consecutive patients from 1 July 2009 to 31 August 2009 in 22 ICUs across mainland China. We excluded patients who were admitted for less than 24 hours (n = 1623), younger than 18 years (n = 127), receiving chronic hemodialysis (n = 29), receiving renal transplantation (n = 1) and unknown reasons (n = 28). There were 1255 patients in the final analysis. AKI was diagnosed and classified according to RIFLE criteria.

RESULTSThere were 396 patients (31.6%) who had AKI, with RIFLE maximum class R, I, and F in 126 (10.0%), 91 (7.3%), and 179 (14.3%) patients, respectively. Renal function deteriorated in 206 patients (16.4%). In comparison with non AKI patients, patients in the risk class on ICU admission were more likely to progress to the injury class (odds ratio (OR) 3.564, 95% confidence interval (CI) 1.706 - 7.443, P = 0.001], while patients in the risk class (OR 5.215, 95% CI 2.798-9.719, P < 0.001) and injury class (OR 13.316, 95% CI 7.507-23.622, P < 0.001) had a significantly higher probability of deteriorating into failure class. The adjusted hazard ratios for 90-day mortality were 1.884 for the risk group, 3.401 for the injury group, and 5.306 for the failure group.

CONCLUSIONSThe prevalence of AKI was high among critically ill patients in Chinese ICUs. In comparison with non-AKI patients, patients with RIFLE class R or class I on ICU admission were more susceptibility to progression to class I or class F. The RIFLE criteria were robust and correlated well with clinical deterioration and mortality.

OBJECTIVETo investigate the risk factors of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSThe clinical data of 534 cases of 533 patients undergoing allo-HSCT during Jan 2004 and Sep 2012 were retrospectively analyzed. The effects of donor-recipient HLA mismatching, recipient age, donor age, donor-recipient sex combination, donor-recipient relationship, HSC source, conditioning regimen with or without total body irradiation (TBI) and HLA loci on intestinal aGVHD with different severity were analyzed by Logistic regression.

RESULTSIntestinal aGVHD occurred in 123(23.0%) cases, with 86(16.1%) cases of stage 1 intestinal aGVHD(16.1%) and 37(6.9%) cases of stage 2 to 4 intestinal aGVHD. Multivariate analysis showed that donor-recipient HLA mismatching (OR=2.519, P=0.002), increasing donor age (OR=1.034, P=0.003), female donor for male recipient (OR=1.855, P=0.007) were risk factors for intestinal aGVHD, HLA-B38 (OR=0.256, P=0.032) was its protective factor. Donor-recipient HLA mismatching (OR=2.799, P=0.011), increasing donor age (OR=1.045, P=0.012), HLA-A1 (OR=4.157, P=0.002), A30 (OR=3.143, P=0.005) were risk factors for stage 2 to 4 intestinal aGVHD.

CONCLUSIONOccurrence of intestinal aGVHD and its severity are associated with donor-recipient HLA mismatching, donor age, donor-recipient sex relationships and some HLA loci.

OBJECTIVESTo explore the association of sleep duration with obesity among children in urban areas of China.

METHODSA total of 6 576 children (3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China. A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level. The height, weight, waist circumference (WC) and percentage of body fat (%BF, as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures. The information on demography, lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.

RESULTSThe average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age (P < 0.05). The sleep duration was negatively associated with body mass index (BMI) and WC in both boys and girls after adjustment for confounders (beta value -0.23 and -0.82 for boys, -0.24 and -0.91 for girls, respectively, P < 0.01). However, no significant association of sleep duration with %BF was found. Children who slept less than 9.0 h per night had a higher risk for overweight and obesity (OR = 1.29, 95% CI: 1.01, 1.64) and abdominal obesity (OR=1.38, 95% CI: 1.04, 1.83) as compared with those who slept for 10.0-10.9 h.

CONCLUSIONSShort sleep duration is associated with obesity. It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life.
