ABSTRACT

Dry eye is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms. In recent years, the incidence of dry eye has been increasing year by year, and the diagnosis and treatment of dry eye are constantly evolving and innovating. However, due to the corresponding drawbacks of traditional examination methods and the lack of a large number of clinical trial studies on new examination methods, there is still no unified standard for the diagnosis and treatment of dry eye. In this review, we have performed a broad search for articles discussing different examination methods for dry eye, including promising diagnostic tools and technique, the latest advances, and contradictions, in order to provide a review of dry eye examination methods including the tear volume, the tear film, the eyelid and meibomian gland, and the degree of damage to the epithelial cells of the ocular surface, and provide a reference for the diagnosis and treatment of dry eye.

ABSTRACT

From the process of human immunodeficiency virus-1 (HIV-1) invading cells, the combination of gp120 and CD4 is the first step for HIV-1 to invade cells. Interfering with this process can prevent HIV from recognizing target cells and inhibit virus replication. Therefore, HIV-1 gp120 is an important part of the HIV-1 life cycle. Fostesavir, a phosphatate prodrug derived from the gp120 inhibitor BMS-626529 modified by the prodrug strategy, was approved for the treatment of adult patients with multidrug resistant HIV-1 infection by the US FDA and the European Medicines Agency in 2020 and 2021, respectively. In this review, we focus on the research progress of small molecule inhibitors targeting the interaction of gp120-CD4 from the perspective of medicinal chemistry, in order to provide reference for the subsequent research of gp120 inhibitors.

ABSTRACT

Objective:To detect the expression of interleukin 2 (IL-2)/Janus kinase 3/signal transduction and transcriptional activator 5 (JAK3/STAT5) signaling pathway in peripheral blood of patients with ankylosing spondylitis (AS) and explore its mechanism in the development and progression of AS.Methods:Clinical data, peripheral blood and laboratory tests of 30 patients with active AS (ASA), 30 patients with stable AS (ASS) and 50 healthy subjects (HC) were collected. The mRNA expression levels of JAK3, signal transduction and transcription activator 5a (STAT5a) and signal transduction and transcription activator 5b (STAT5b) were detected by quantitative real-time-polymerase chain reaction (RT-qPCR). The expression levels of JAK3, STAT5a and STAT5b proteins and phosphorylated proteins were detected by Western-blot. Plasma IL-2 concentration was determined by enzyme-linked immunosorbent assay (ELISA). Two independent samples t-test or one-way analysis of variance were used for measurement data consistent with normal distribution, LSD- t test was used for pairwise comparison between the three groups, Mann-Whitney U test or Kruskal-Wallis H test was used for non-normal distribution, χ2 test was used for correlation analysis of categorical variables. Spearman correlation analysis was used for correlation analysis between variables, and receiver operating characteristic (ROC) curve was used to evaluate the value of JAK3, STAT5a and STAT5b mRNA expression levels in monitoring AS activity. Results:① The mRNA expression levels of JAK3, STAT5a and STAT5b were significantly different among the three groups ( F=65.98, P<0.001; F=21.15, P<0.001; F=13.67, P<0.001). JAK3 mRNA expression in ASA group (2.5±0.9) was significantly higher than that in ASS group (1.1±0.4) and healthy subjects (1.0±0.5), the difference was statistically significant (both P<0.001). The mRNA expression level of STAT5a in ASA group (1.4±0.3) was significantly higher than that in ASS group (0.9±0.3) and healthy subjects group (1.0±0.3), the difference was statistically significant (both P<0.001). STAT5b mRNA expression level in ASA group (1.5±0.6) was significantly higher than that in ASS group (1.0±0.4) and healthy subjects (1.0±0.4), the difference was statistically significant (both P<0.001). The expression level of JAK3 mRNA in HLA-B27 positive group (1.9±1.0) was higher than that in HLA-B27 negative group (1.4±0.6), and the difference was statistically significant ( t=-2.22, P=0.032). The phosphorylation levels of JAK3, STAT5a and STAT5b showed statistically significant differences among the three groups ( F=91.56, P<0.001; F=25.15, P< 0.001; F=178.59, P<0.001). The phosphorylation level of JAK3 protein in ASA group (1.04±0.08) was significantly higher than that in ASS group (0.568±0.019) and healthy subjects (0.536±0.064), the difference was statistically significant (both P<0.001). The phosphorylation level of STAT5a protein in ASA group (1.166±0.096) was significantly higher than that in ASS group (0.923±0.018) and healthy subjects (0.911±0.017), the difference was statistically significant (both P<0.001). The phosphorylation level of STAT5b protein in ASA group (0.81±0.05) was significantly higher than that in ASS group (0.21±0.03) and healthy subjects (0.24± 0.07), the difference was statistically significant (both P<0.001). The difference of plasma IL-2 concentration among the three groups was statistically significant ( F=3.32, P=0.040). The IL-2 concentration in the ASA group [(110±40) pg/ml] was significantly higher than that in the ASS group [(89±40) pg/ml] and the healthy group [(88±39) pg/ml], the difference was statistically significant ( P=0.044, P=0.016). ② Spearman correlation analysis showed that STAT5a mRNA expression level was positively correlated with platelets in AS patients ( r=0.353, P=0.006). JAK3 mRNA expression level in ASA group was positively correlated with IL-2 concentration ( r=0.766, P<0.001), and negatively correlated with estimated glomerular filtration rate ( r=-0.485, P=0.007). STAT5a mRNA expression level was positively correlated with erythrocyte sedimentation rate ( r= 0.680, P<0.001), and STAT5b mRNA expression level was positively correlated with hypersensitive C-reactive protein (CRP) ( r=0.823, P<0.001). ③ The ROC curve showed that JAK3 mRNA expression level predicted the area under ROC curve (AUC) of ASA with a 95% CI of 0.920 (0.853, 0.987), sensitivity and specificity of 86.7% and 90.0%, respectively. STAT5a mRNA expression level predicted the AUC 95% CI of ASA was 0.874 (0.787, 0.961), and the sensitivity and specificity were 96.7% and 66.7%, respectively. STAT5b mRNA expression level predicted the AUC 95% CI of ASA was 0.749 (0.617, 0.881), and the sensitivity and specificity were 73.3% and 80.0%, respectively. Conclusion:This study suggests that IL-2/JAK3/STAT5 may be involved in the pathogenesis of AS, and JAK3 mRNA can be used as a biological indicator to monitor the activity of AS disease.

ABSTRACT

Objective To investigate the expression levels of basic leucine zipper and W2 domain 2 (BZW2) and isovaleryl-CoA dehydrogenase (IVD) in hepatocellular carcinoma (HCC) and evaluate their effect on clinical prognosis of liver transplant recipients with HCC. Methods Pathological specimens and clinical data of 87 liver transplant recipients with HCC were collected and retrospectively analyzed. The recurrence and metastasis of HCC after liver transplantation were assessed. Immunohistochemical staining was used to detect the expression levels of BZW2 and IVD. The relationship between BZW2, IVD and clinicopathological parameters of HCC and their effect on postoperative recurrence and clinical prognosis of the recipients was analyzed. Results Among 87 recipients, 31 cases recurred with a recurrence rate of 36%. HCC recurred at postoperative 2-49 months and the median recurrence time was postoperative 7 months. Immunohistochemical staining demonstrated that the positive expression rate of BZW2 in the HCC tissues was significantly higher than that in normal liver tissues (76% vs. 30%), and the positive expression rate of IVD was significantly lower compared with that in normal liver tissues (51% vs. 69%) (both P < 0.01). BZW2 expression was significantly correlated with tumor diameter and tumor capsule (both P < 0.05), whereas IVD expression was significantly associated with tumor diameter, alpha-fetoprotein (AFP) level, tumor, node and metastasis (TNM) staging and whether vascular invasion was found or not (all P < 0.05). In the high BZW2 expression group, the cumulative recurrence rate of HCC was significantly higher and the cumulative survival rate was significantly lower than those in the low BZW2 expression group. In the low IVD expression group, the cumulative recurrence rate of HCC was significantly higher and the cumulative survival rate was significantly lower compared with those in the high IVD expression group (all P < 0.05). Conclusions The expression level of BZW2 protein is up-regulated, whereas that of IVD protein is down-regulated in the HCC tissues. Moreover, the cumulative recurrence rate of HCC is relatively high and the cumulative survival rate is relatively low in liver transplant recipients with high BZW2 expression and low IVD expression.

ABSTRACT

Carbon dioxide peaking and carbon neutrality have become hot issues of political and economic activities in China and abroad. The structure and development of various industries in China will be profoundly affected in the process of accomplishing "Dual Carbon" goals. Eco-agriculture of Chinese medicine(EACM) highlights the balance and sustainable development of the ecosystem while producing high-quality medicinal materials. With chemically synthesized fertilizers, pesticides, and growth regulators prohibited, EACM emphasizes the recycling of agricultural and sideline products and the reduction of waste output, which results in the minimal negative impact on the ecological environment. Therefore, it is typical agriculture with low-carbon sources and high-carbon sinks. This study reviewed the mechanism and potential of EACM in carbon dioxide peaking and carbon neutrality, analyzed the specific ways of EACM in reducing carbon sources and increasing carbon sinks based on the typical ecological planting pattern, and proposed the point of view to strengthen EACM as well as the "Dual Carbon" theory and research methods, so as to direct low-carbon and efficient deve-lopment. Furthermore, this study advocated to comprehensively promote the transformation of Chinese medicine production from chemical agriculture to eco-agriculture to improve the comprehensive benefits of contribution rate of carbon neutrality, explore and establish carbon sink compensation mechanism to ensure the sustainable and healthy development of EACM, and strengthen the training of EACM and "Dual Carbon" theory and technologies to continuously improve the capacity of EACM in sustainable development. This study is expected to provide a reference for the development of ecological functions in EACM and the development of economic functions through ecological functions.

ABSTRACT

Objective To evaluate the predictive values of albumin-bilirubin (ALBI) and easy albumin-bilirubin (EZ-ALBI) scores for early survival (postoperative 3 months) of recipients with liver failure after liver transplantation. Methods Clinical data of 137 recipients diagnosed with liver failure and underwent liver transplantation were retrospectively analyzed. The optimal cut-off values of preoperative ALBI, EZ-ALBI and MELD scores to predict early survival of recipients with liver failure after liver transplantation were determined by the area under the receiver operating characteristic (ROC) curve. The risk factors of early death of recipients with liver failure after liver transplantation were identified by univariate and multivariate Cox regression analyses. The effects of different ALBI and EZ-ALBI levels upon early prognosis of recipients with liver failure after liver transplantation were analyzed. Results The optimal cut-off values of ALBI, EZ-ALBI and MELD scores were 0.21, -19.83 and 24.36, and the AUC was 0.706, 0.697 and 0.686, respectively. Univariate Cox regression analysis showed that preoperative alanine aminotransferase(ALT)≥50 U/L, aspartate aminotransferase(AST)≥60 U/L, ALBI score≥0.21 and EZ-ALBI score≥-19.83 were the risk factors for early postoperative death of recipients with liver failure after liver transplantation (all P < 0.05). Multivariate Cox regression analysis demonstrated that preoperative ALBI score≥0.21 was an independent risk factor for early postoperative death of recipients with liver failure after liver transplantation (P < 0.05). According to the optimal cut-off value of ALBI score, the early survival rates in the ALBI < 0.21 (n=46) and ALBI≥0.21(n=91) groups were 93.5% and 64.8%, and the difference was statistically significant (P < 0.05). According to the optimal cut-off value of EZ-ALBI score, the early survival rates in the EZ-ALBI < -19.83(n=60) and EZ-ALBI≥-19.83(n=77) groups were 88.3% and 63.6%, and the difference was statistically significant (P < 0.05). Conclusions Preoperative ALBI score is of high predictive value for early survival of recipients with liver failure after liver transplantation, which could be utilized as a reference parameter for selecting liver transplant recipients.

ABSTRACT

Objective@#To investigate the correlation between body composition and eating habits among medical students, and to provide evidence for health promotion.@*Methods@#In December 2021, stratified cluster random sampling method was used to conduct a questionnaire survey and body composition assessment among 445 students in grade one to grade four in Jining Medical University.@*Results@#There were 152 girls (53.3%) and 45 boys (28.1%) with low skeletal muscle mass. Totally 167 students ( 37.5% ) had lower muscle mass, including 115 females (40.4%) and 49 males (30.6%). High body fat percentage was found in 259 (58.2%) students, including 179 females (62.8%) and 80 males (50.0%). There were 192 students (43.1%) with abnormal waist to hip ratio, with 139 females (48.8%) and 53 males (33.1%). In addition, emotional eating score of female students was significantly higher than that of male students(6.85±2.24, 6.11±2.69, t =2.96, P <0.05). Cognitive restricted eating was positively correlated with skeletal muscle mass and musde mass( r=0.13, 0.13, P <0.05). Emotional eating was positively correlated with body fat percentage, body fat and waist hip ratio( r =0.20, 0.20, 0.16, P <0.05). Unrestricted eating was positively correlated with body fat percentage, body fat and waist hip ratio( r =0.15, 0.18, 0.15, P <0.05). Multiple linear regression analysis showed that gender, family residence, physical activity and cognitive eating were associated with skeletal muscle mass and muscle mass of medical students( P <0.05).@*Conclusion@#With low skeletal muscle mass, low muscle mass, body fat percentage and waist and hip high ratio, reasonable eating habits combined with resistance exercise should be adopted to improve their physical health.

ABSTRACT

Objective: To study the effects of Homeobox C10 (HOXC10) on biological characteristics such as migration, invasion and proliferation of glioma cancer cells and to explore the role of HOXC10 gene in glioma microenvironment. Methods: The expression level of HOXC10 in high grade glioma (glioblastoma) and low grade glioma and its effect on patient survival were analyzed by using The Cancer Genome Atlas (TCGA) and Chinese Glioma Genome Atlas (CGGA) database. Hoxc10-siRNA-1, HOXC10-siRNA-2 and siRNA negative control (NC) were transfected into U251 cells according to the operation instructions of HOXC10-siRNA transfection. 100 ng/ mL recombinant protein chemokine ligand 2 (reCCL2) was added into the transfection group, and was labeled as HOXC10-siRNA-1+ reCCL2 and HOXC10-siRNA-2+ reCCL2 groups. The expressions of HOXC10 mRNA and target protein in each group was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and western blot. The proliferation ability of cells in each group was detected by cell counting kit 8 (CCK8) method. The migration ability of cells was detected by Transwell assay and Nick assay, and cell apoptosis was detected by flow cytometry. The expression of chemokines in each group was detected by multiple factors. Co-incubation assays were performed to determine the role of HOXC10 and chemokine ligand 2 (CCL2) in recruiting and polarizing tumor-associated macrophages (M2-type macrophages). Results: The median expression level of HOXC10 in high grade gliomas was 8.51, higher than 1.00 in low grade gliomas (P<0.001) in TCGA database. The median expression level of HOXC10 in high grade gliomas was 0.83, higher than 0.00 in low grade gliomas (P=0.002) in CGGA database. The 5-year survival rate of patients with high HOXC10 expression in TCGA database was 28.2%, lower than 78.7% of those with low HOXC10 expression (P<0.001), and the 5-year survival rate of patients with high HOXC10 expression in CGGA database was 20.3%, lower than 58.0% of those with low HOXC10 expression (P<0.001). The numbers of cell migration in HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (45±3) and (69±4) respectively, lower than (159±3) in NC group (P<0.05). The cell mobility of HOXC10-siRNA-1 group and HOXC10-siRNA-2 group at 48 hours were (15±2)% and (28±4)% respectively, lower than (80±5)% of NC group (P<0.05). The expressions of vimentin in HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (141 740.00±34 024.56) and (94 655.00±5 687.97), N-cadherin were (76 810.00±14.14) and (94 254.00±701.45), β-catenin were (75 786.50±789.84) and (107 296.50±9 614.53), lower than (233 768.50±34 114.37), (237 154.50±24 715.50) and (192 449.50±24 178.10) of NC group (P<0.05). The A value of HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (0.44±0.05) and (0.32±0.02) at 96 hours, lower than 0.92±0.12 of NC group (P<0.05). The apoptosis rates of HOXC10-siRNA-1 group and HOXC10 siRNA-2 group were (10.23±1.24)% and (13.81±2.16)%, higher than (4.60±0.07)% of NC group (P<0.05). The expression levels of CCL2 in U251 cells in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were (271.63±44.27) and (371.66±50.21), lower than (933.93±29.84) in NC group (P<0.05). The expression levels of CCL5 (234.81±5.95 and 232.62±5.72), CXCL10 (544.13±48.14 and 500.87±15.65) and CXCL11 (215.75±15.30 and 176.18±16.49) in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were higher than those in NC group (9.98±0.71, 470.54±18.84 and 13.55±0.73, respectively, P<0.05). The recruited numbers of CD14(+) THP1 in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were (159.33±1.15) and (170.67±1.15), respectively, lower than (360.00±7.81) in NC group (P<0.05), while addition of reCCL2 promoted the recruitment of CD14(+) THP1 cells (287.00±3.61 and 280.67±2.31 in HOXC10-siRNA-1+ reCCL2 group and HOXC10-siRNA-2+ reCCL2 group, respectively, P<0.05). The expressions level of M2-type macrophage-related gene TGF-β in HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (0.30±0.02) and (0.28±0.02), respectively, lower than (1.06±0.10) in NC group (P<0.05). The expressions level of M1-related gene NOS2 in HOXC10-siRNA-1 and HOXC10-siRNA-2 were (11 413.95±1 911.85) and (5 894.00±945.21), respectively, higher than (13.39±4.32) in NC group (P<0.05). Conclusions: The expression of HOXC10 in glioma is high and positively correlated with the poor prognosis of glioma patients. Knockdown of HOXC10 can inhibit the proliferation, migration and metastasis of human glioma U251 cells. HOXC10 may play an immunosuppressive role in glioma microenvironment by promoting the expression of CCL2 and recruiting and polarizing tumor-associated macrophages (M2 macrophages).

ABSTRACT

Objective@#To investigate the experience of child sexual abuse (CSA) and depressive symptoms among young men who sex with men (YMSM) in Guangzhou, and then to explore the impact of CSA on depressive symptoms.@*Methods@#A convenient sampling method was used to recruit MSM. YMSM who aged 18-24 and have lived in Guangzhou for more than 3 months were included in this study. Data on demographic characteristics, homosexual partners seeking behaviors, sexual orientation, CSA experience and depression were collected through an electronic questionnaire. χ 2 tests were used to compare the proportion of CSA and depressive symptoms among YMSM with different characteristics. Logistic regressions were preformed to assess the impact of CSA on depression.@*Results@#The proportion of CSA experience and depressive symptoms among participants were 31.51% (115/365) and 47.95% (175/365), respectively. Participants with junior high school education or lower and who sought homosexual partners offline reported(75.00%,62.22%) a higher proportion of depressive symptoms( χ 2=7.97,4.19, P <0.05). After adjusting for factors e.g. ethnicity, residence, resident duration in Guangzhou, studentship, education, monthly income, sexual orientation and homosexual partners seeking behaviors, the multivariable Logistic regression model showed that YMSM with CSA experience (a OR=1.81, 95%CI =1.12-2.93) were more likely to have depressive symptoms than those without CSA experience.@*Conclusion@#The prevalence of CSA experience and depressive symptom is relatively high among YMSM in Guangzhou, and CSA experience is associated with higher risk of depressive symptoms. More attention should be paid to strengthen the psychological intervention for YMSM, especially for those who experienced CSA, so as to reduce the risk of depression and improve mental health among YMSM.

ABSTRACT

Objective:To retrospectively analyze the effects of vitamin D3 supplementation on clinical remission of patients with Crohn′s disease (CD) in the treatment of infliximab (IFX).Methods:From January 2014 to January 2020, 73 patients with initial moderate to severe CD (50 patients with vitamin D deficiency (the level of serum 25-hydroxyvitamin D (25(OH)D)<50 nmol/L)) receiving IFX treatment at Department of Gastroenterology were screened from the clinical database of the Second Affiliated Hospital of Wenzhou Medical University. Harvey-Bradshaw index (HBI) was applied to evaluate the disease activity of CD patients. All the patients underwent IFX treatment (5 mg/kg) for at least 54 weeks. According to whether vitamin D3 (125 U/d) was supplemented during IFX treatment, the patients were divided into supplemented group ( n=37) and non-supplemented group ( n=36). In supplemented group, the level of 25(OH) D of patients at the 54th week was compared with that before IFX treatment. At the 54th week, the clinical remission rate and decline range of HBI were compared between supplemented group and non-supplemented group. And the influencing factors of clinical remission rate were analyzed in CD patients. Paired t test, independent sample t test, chi-square test and multivariable logistic regression were used for statistical analysis. Results:In supplemented group, the level of serum 25(OH)D at the 54th week was higher than that before IFX treatment ((50.83±15.45) nmol/L vs. (37.68±16.75) nmol/L), and the difference was statistically significant ( t=-4.55, P<0.001). At the 54th week, the clinical remission rate of supplemented group was higher than that of non-supplemented group (83.8%, 31/37 vs. 61.1%, 22/36), the decline range of HBI was larger than that of non-supplemented group (7.41±3.00 vs. 6.28±2.75), and the differences were statistically significant ( χ2=4.71, t=2.41; P=0.030 and 0.023). The results of multivariable logistic regression analysis showed that vitamin D3 supplementation was an independent factor affecting the clinical remission rate in CD patients ( n=73) and the patients with vitamin D deficiency ( n=50) ( b= -1.67 and -1.92 , P=0.015 and 0.019). Conclusions:Vitamin D3 supplementation can significantly improve the clinical remission rate in CD patients with IFX treatment, especially in CD patients with vitamin D deficiency.

ABSTRACT

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

ABSTRACT

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

ABSTRACT

Hilar cholangiocarcinoma(HCCA) is a hotpot and a difficult point in the field of hepatobiliary surgery. HCCA is the most common type of cholangiocarcinoma and is characterized by atypical early clinical manifestations, rapid progression and poor prognosis. There is no specific marker for HCCA and its preoperative diagnosis and evaluation mainly relies on imaging examination. Surgical treatment is still the main treatment, but most patients have lost the opportunity of surgical resection by the time of treatment. In recent years, a large number of studies have been conducted on the diagnosis and treatment of HCCA at home and abroad, and the efficacy of HCCA has been improved. Perioperative management, including the selection of preoperative drainage and perioperative chemoradiotherapy and others, improved postoperative survival. Among them, the application of preoperative radiotherapy and chemotherapy in the field of liver transplantation has achieved quite good results. Targeted therapy and immunotherapy have provided new treatment methods for HCCA. This paper reviews the diagnosis and multimodal treatment of HCCA.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection may lead to multisystem inflammatory syndrome in children(MIS-C). MIS-C mostly occurs in older children and adolescents who have laboratory or epidemiological evidence of SARS-CoV-2 infection.The clinical manifestations include persistent fever, hypotension, elevated inflammation markers, and symptoms of multiple organ involvement, which is similar to Kawasaki disease.Once the disease occurs, it can progress rapidly and worsen in a short time, and most children require intensive care admission.Although the overall prognosis is good, some patients have adverse results such as death.We should strengthen the monitoring and management of suspected children and improve the level of diagnosis and treatment of the disease.

ABSTRACT

Objective:To investigate the relationship between polymorphisms and haplotypes of cyclin-dependent kinase inhibitor 2B antisense RNA 1 ( CDKN2 B- AS1) gene and the risk of ulcerative colitis (UC). Methods:From January 2012 to January 2021, a total of 534 UC patients diagnosed at the Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University (Yuying Children′s Hospital) and during the same period 560 gender- and age-matched healthy controls were selected. Genotypes of CDKN2 B- AS1 (rs1063192, rs10757274, rs10757278, rs1333048, rs2383207) in venous blood were determined by matrix assisted laser desorption ionization time-of-flight mass spectrometry technique. Unconditional logistic regression was used to analyze the difference in the distribution of CDKN2 B- AS1 gene polymorphisms between UC patients and healthy controls, as well as the influence on the clinicopathologic characteristics of UC patients. Software Haploview 4.2 was used to analyze the linkage disequilibrium and haplotype. Chi-square test was used for statistical analysis. Results:The frequencies of variant genotype (AG+ GG) and variant allele (G) of rs1063192 in UC patients were higher than those in healthy controls (32.4%, 173/534 vs. 24.8%, 139/560; 18.1%, 193/1 068 vs. 13.7%, 153/1 120), and the differences were statistically significant ( OR=1.45 and 1.40, 95% confidence interval(95% CI) 1.12 to 1.89 and 1.11 to 1.77, P=0.006 and 0.004, corrected P=0.030 and 0.020). The frequency of variant allele (G) of rs10757274 in UC patients was lower than that in healthy controls (34.7%, 371/1 068 vs. 39.5%, 442/1 120), and the difference was statistically significant ( OR=0.82, 95% CI 0.69 to 0.98, P=0.025). However, the difference was not significant after Bonferroni correction (corrected P>0.05). According to the Montreal classification, the frequency of homozygous variant genotype (GG) of rs1063192 in the patients with extensive colitis was higher than that in patients with proctitis plus left-sided colitis (6.6%, 14/211 vs. 1.9%, 6/323), and the difference was statistically significant ( OR=3.92, 95% CI 1.47 to 10.42, P=0.006, corrected P=0.030). There was linkage disequilibrium among rs10757274, rs2383207, rs10757278 and rs1333048 of CDKN2 B- AS1 gene. The frequency of haplotype GGGC in UC patients was lower than that in healthy controls (33.3%, 355.5/1 068 vs. 37.8%, 423.4/1 120), and the frequency of haplotype AGGC in UC patients was higher than that in healthy controls (6.7%, 71.7/1 068 vs. 3.6%, 40.3/1 120), and the differences were statistically significant ( χ2=4.81 and 11.16, P=0.028 and<0.001). Conclusions:The variation of rs1063192 in CDKN2 B- AS1 gene may increase the risk of UC. The risk of extensive colitis in patients carrying homozygous variant genotype (GG) of rs1063192 may rise. Among the haplotypes composed of rs10757274, rs2383207, rs10757278 and rs1333048, the risk of UC may decrease in the individuals carrying haplotype GGGC. However, the risk of UC may increase in the individuals carrying haplotype AGGC. The correlation between the variation of 10757274 and the risk of UC still needs to be further verified by expanding the sample size.

ABSTRACT

Three patients received surgical treatment in Department of Hepatobiliary Surgery of Mengchao Hepatobiliary Hospital from December 2020 to February 2022. Ceftriaxone sodium was given prophylactically before and after operation,and gallbladder silt stones were found by imaging examination on the 3rd, 3rd and 2nd after surgery in 3 patients, respectively. No special treatment was given,after the withdrawal of ceftriaxone sodium for 28, 38 and 48 d,radiographic examination showed that calculi disappeared spontaneously. It is suggested that the pseudolithiasis may be related to administration of ceftriaxone sodium.

ABSTRACT

Objective:To explore the predictive value of platelet-albumin-bilirubin(PALBI)score for tumor recurrence after liver transplantation(LT)in patients with hepatocellular carcinoma(HCC).Methods:Clinical data were retrospectively reviewed for 102 HCC patients undergoing LT from January 2010 to December 2020.The predictive value of PALBI score for tumor recurrence after LT and the risk factors for tumor recurrence after LT were examined by receiver operating characteristic(ROC)curve, Kaplan-Meier method and univariate/multivariate Cox regression.Results:The optimal cutoff value of preoperative PALBI score for predicting recurrence was -3.82 with ROC curve, Youden's index 0.317 and area under the ROC curve 0.679.Survival analysis was performed using a PALBI cutoff value of -3.82 as boundary group.The results showed that significant differences existed in 1/3/5-year tumor recurrence rates(17.9% vs.50.0%, 26.9% vs.62.5%, 29.5% vs.62.5%)after low PALBI and high PALBI( P<0.05 for all). Univariate analysis indicated that preoperative tumor maximal diameter, tumor number, Milan criteria, alpha fetoprotein(AFP)level, microvascular invasion, portal venous tumor thrombus, and PALBI score were significantly associated with postoperative tumor recurrence( P<0.05 for all). And multivariate analysis revealed that Milan criteria, AFP level and PALBI score were independent risk factors for postoperative tumor recurrence( P<0.05). Conclusions:Preoperative PALBI score offers some predictive value for postoperative tumor recurrence in HCC patients post-LT.When preoperative PALBI score ≥-3.82 in HCC patients, postoperative tumor recurrence rate is relatively high.
