ABSTRACT
Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
ABSTRACT
Objective:To investigate the effect of focal adhesion kinase related non kinase (FRNK) on the activation and migration of hepatic stellate cells (HSCs).Methods:Human liver tissue was divided into healthy control group and fibrosis group from March 2019 to September 2019 in Affiliated Hospital of Guizhou Medical University. C57BL/6 mice were divided into wild type (WT) and FRNK gene knockout type (FRNK -/-) groups. The liver fibrosis model was established with carbon tetrachloride (CCl 4). After that, FRNK gene overexpression (Ad-FRNK) was constructed with adenovirus vector. HE and Masson staining were used to evaluate the pathological changes and fiber deposition of liver tissue. Western blot was used to detect the expression of PY397-FAK and α-SMA protein. Mouse primary HSCs were extracted, and the effect of FRNK on HSCs migration was detected by wound healing, activation of Rac and Rho was detected by Western blot. Results:The expression of PY397-FAK protein in human liver tissue with hepatic fibrosis was significantly higher than that in healthy control group (0.88±0.09 vs. 0.73±0.09). FRNK was significantly lower than that in control group(0.68±0.09 vs. 0.79±0.11). After animal model was set up, the degree of liver fibrosis in FRNK -/-mice (153±13)% was more serious than that in WT (100%) group. The expression of PY397-FAK and α-SMA protein was significantly elevated (2.50±0.23 vs. 0.75±0.09, 1.46±0.20 vs. 0.92±0.10). After FRNK gene was re-expressed (100%), the degree of liver fibrosis was mainly reversed [(74±6)%], and the expression of PY397-FAK and α-SMA was accordingly decreased(0.68±0.11 vs. 1.12±0.19,0.68±0.10 vs. 0.85±0.06). In vitro, FRNK inhibited the migration of HSCs [WT∶FRNK -/-∶Ad-FRNK,(339±49)%∶(580±53)%∶(259±33)%] and the activation of Rac and Rho proteins (Rac: 0.54±0.07 vs. 0.91±0.10 vs. 0.77±0.12,Rho:0.45±0.05 vs. 0.64±0.06 vs. 0.53±0.07), all P<0.01. Conclusions:FRNK can inhibit the activation and migration of HSCs which contributed to liver fibrosis. The potential mechanism is related to down regulation of PY397-FAK and inhibition of Rac and Rho activation.
ABSTRACT
Objective:To observe the effect of nocturnal nutritional support on the improvement of nutritional status and liver function in patients with hepatitis B cirrhosis.Methods:A total of 60 patients with hepatitis B cirrhosis who were treated at the Affiliated Hospital of Guizhou Medical University from April 2011 to August 2018 were selected, and they were divided into nutritional intervention group and control group according to the random digital table method, with 30 cases in each group.The two groups were given basic medical treatment, and the nutritional intervention group was given basic treatment plus 30g of complex functional nutrients, once per night, for 12 weeks.The changes of liver function and nutritional status of the two groups were observed every 4 weeks, and the occurrence of complications was recorded.Results:Before intervention, the ALB, PA, TBIL, body mass index, triceps cutaneous fold thickness and grip strength had no statistically significant differences between the two groups(all P>0.05). After 12 weeks of intervention, the albumin [(32.61±1.78) g/L], pre-albumin [(116.65±11.92) g/L], total bilirubin [(36.6±5.86)μmol/L], body mass index [(22.23±2.92) kg/m 2], skinfold [(17.34±1.31) mm], the grip strength [(23.36±2.44)kg] in the intervention group were superior to the control group[(30.38±1.58)g/L, (101.22±7.76)g/L, (47.75±4.83)μmol/L, (21.07±2.11)kg/m 2, (16.07±1.40)mm, (20.01±2.70)kg], the differences were statistically significant between the two groups( t=4.946, 5.105, 5.881, 2.407, 2.272, 3.805, all P<0.05). The incidence of the complications in the intervention group was 10%(3/30), which in the control group was 33%(10/30), the difference was statistically significant between the two groups(χ 2=4.381, P=0.033). Conclusion:Providing nutritional support at night can improve the nutritional status of patients with hepatitis B cirrhosis, promote the repair of liver function, and reduce the incidence of complications.
ABSTRACT
Objective@#To investigate the association between the whole blood riboflavin level and the occurrence, development and prognosis of esophageal squamous cell carcinoma (ESCC) in China. @*Methods@#From March 2014 to September 2018, ESCC patients from three hospitals (the Affiliated Hospital of Medical College of Shantou University, Shantou Central Hospital in Southern Chaoshan area and First Affiliated Hospital of Zhengzhou University in Northern Taihang Mountain) were selected as a case group; non-esophageal patients who had a physical examination were selected as a control group. The case and control group were paired by age (±5 years) and a 1:1 ration. A total of 1 528 subjects were enrolled including 764 patients in the case group and 764 patients in the control group. About 3-5 ml venous blood samples were collected, and the erythrocyte glutathione reductase activity coefficient (GRAC) was measured to assess the whole blood riboflavin level. A multivariate conditional logistic regression model was used to analyze the association between the GRAC and the risk of ESCC. The association between the GRAC and the prognosis of ESCC was analyzed by using Cox proportional risk regression model based on 288 patients with complete survival data. They were divided into two groups, the high GRAC group (GRAC≥7.87) group and the low GRAC group (GRAC<7.87) according to the strongest correlation between the total survival time, survival outcome and GRAC (GRAC=7.87). @*Results@#Among the 1 528 patients, 958 patients were from Southern Chaoshan area, including 479 patients in the case group with an average age about (59.90±9.34) years and 479 patients in the control group with an average age about (59.55±8.77) years. Other 570 patients were from Northern Taihang Mountain area, including 285 patients in the case group with an average age (58.39±5.19) years and 285 patients in the control group with an average age about (58.74±4.57) years. The multivariate conditional logistic regression showed that the OR (95%CI) of the GRAC and the risk of ESCC was 1.009 (0.998-1.019). The Cox proportional hazard regression model analysis showed that the HR (95%CI) of the high GRAC group was 1.712 (1.034-2.824) compared with the low GRAC group in the 50-70 years group. @*Conclusion@#The whole blood riboflavin level might not be associated with the occurrence of ESCC. The high whole blood riboflavin level would be more beneficial to the prognosis of ESCC patients aged 50-70 years.
ABSTRACT
Objective@#To observe the efficacy and safety related measures by blocking mother-to-child transmission of hepatitis B virus with high viral load and HBeAg positivity during pregnancy in Guizhou province.@*Methods@#Outpatient and inpatient cases of the Department of Infectious Diseases and Obstetrics of Guizhou Medical University Affiliated Hospitals from May 2016 to July 2017 were retrospectively divided into intervention group, non-intervention group and non- hepatitis B pregnant women group; with 75 cases in each group. HBsAg and HBeAg were positive in the intervention group. Pregnant women with HBV DNA ≥106 IU/ml were treated with anti-HBV therapy for 24 to 28 weeks of gestation until delivery. According to oral drugs, they were divided into tenofovir (TDF) group or telbivudine (LDT) group, non-intervention group (HBsAg and HBeAg positive), HBV DNA positive pregnant women, pregnant women with no anti-HBV drugs, non-hepatitis B pregnant women (normal pregnant women without HBV infection). Infants and young children born to the three groups of women were immunized with the national viral hepatitis B action plan. The gestational weeks and Apgar scores at birth, delivery mode, feeding mode, sex and 7-months-old age were observed and counted. Serum hepatitis B markers (HBVM) and HBV DNA were quantitatively detected. HBVM was detected by time-resolved fluorescence immunoassay (TRFIA), and HBV DNA was detected by real-time PCR (FQ-PCR). The changes of liver parameters, HBsAg, HBeAg, HBV DNA, adverse drug reactions and treatment response of pregnant intervention group before medication (12-24 weeks of gestation), 4 weeks of medication (28-32 weeks of gestation), 36-40 weeks of gestation (36-40 weeks of gestation) were statistically calculated. A t-test was used to compare the data between the measurements. Data measurements within the groups were analyzed using rank -sum test.@*Results@#In the intervention group, therapeutic medications showed no differences in demographic and clinical characteristics between TDF group and LDT group, including liver parameters, HBsAg, HBeAg and log10HBV DNA level. Compared with pre-treatment (TDF group: 4.84 ± 2.01; LDT group: 5.08 ± 1.99), TDF and LDT were significantly lower at the end of pregnancy (TDF group: 3.06 ± 0.66; LDT group: 3.51 ± 1.20). P < 0.05); and the treatment response rate was 100%. There were no serious adverse events in the intervention group. Infants and young children (7-months-old) in the intervention group had negative HBsAg, HBeAg and HBV DNA. The mother-to-child transmission rate of HBV was zero, with blocking rate of 100%. In addition, both infants and young children had different degrees of hepatitis B protective antibodies (anti-HBs, M: 144.33), and their antibody titers were higher than that of non-intervention group (anti-HBs, M: 65.91) and non-hepatitis B pregnant women (anti-HBs, M: 58.43). The difference was statistically significant (P < 0.05), and there was no significant correlation between the use of antiviral and the way of delivery and feeding. Outcomes of mother-to-child transmission of HBV infection in infants and young children (7-months-old) delivered by three groups of pregnant women in the non-intervention groups had 20.0% (15/75)/ 17.3% (13/75) HBsAg/HBeAg positivity rate, and 17.3% (13/75) HBV DNA positivity rate. Overall, mother-to-child transmission rate of HBV infection was 20% (15/75). Furthermore, the relationship between mother's HBV DNA load and infant HBV infection in the non-intervention group showed mother's HBV DNA ≥106 IU/ml.@*Conclusion@#In the non-intervention group, mother-to-child transmission of HBV occurred, and infected mothers HBV DNA was ≥106 IU/ml before delivery. This suggests that HBeAg positive and high load HBV DNA replication were independent risk factors for mother-to-child transmission of hepatitis B. Therefore, prenatal drug intervention and postpartum standard immune blockade are necessary for high-risk pregnant women with hepatitis B to achieve zero mother-to-child transmission of hepatitis B in real- clinical practice.
ABSTRACT
Objective@#To observe the effects of blueberry and nuclear expression of transcription factor-кb (NF-кb) p65 in an experimental rat model of liver fibrosis.@*Methods@#Forty-five Sprague-Dawley rats were randomly divided into isotonic saline control group (A); model group (B); blueberry juice prevention group (C, 15 g/kg); dan-shao-hua-xian capsule prevention group (D, 1 g/kg); and blueberry juice + dan-shao-hua-xian capsule prevention group (E). Rat liver fibrosis model was established by covalent compound carbon tetrachloride (CCl4). Each prevention group was given the corresponding dose of blueberry juice or (and) dan-shao-hua-xian capsule, and the rats were sacrificed after 8 weeks. The degree of liver fibrosis was evaluated by hematoxylin and eosin stain. A liver tissue of NF-κBp65 was detected by immunohistochemical method. The NF-κBp65 protein expression of liver tissue and transforming growth factor (TGF) β1 was detected by Western blot. Data of multiple groups were compared by one-way analysis of variance, and rank sum test.@*Results@#Immunohistochemistry detected that TGFβ1 protein was mainly expressed in mesenchymal origin of hepatic stellate cells. The expression level of group A (3.75 ± 1.67) was low, while those of group B (9.00 ± 2.07), C (7.33 ± 1.00), D (6.00 ± 1.51), and E (3.5 ± 1.41) were high. However, the expression level of TGF-β1 protein in hepatic tissues of group B was significantly higher than that of group C, D and E [group E: 3.5 ± 1.41, F = 18.350, P < 0.05]. In addition, group D was higher than group E (P < 0.05). The expression of NF- kappa Bp65 protein was very complex, and the expression patterns in different groups were different (Statistical calculation of experimental data were based on expression of liver cells). Compared with group B (4.37 ± 2.13), the relative expression levels of NF-κBp65 protein in-group A (0.46 ± 0.25), group C (2.76 ± 1.01), group D (2.13 ± 1.51), group E (1.88 ± 0.99) were significantly decreased (F = 27.490, P < 0.05), and the expression trend was consistent with TGFβ1 protein. Western blot detected NF-κBp65 protein in liver tissues of rats. Compared with group A, levels in groups B, C, D and E were significantly increased (F = 96.983, P < 0.05), and groups C, D and E were significantly lower. The E group was significantly lower than the C group (F = 96.983, P < 0.05), and the degree of hepatic fibrosis was lower in each prevention group than in the B group (T = 24.1, P < 0.05).@*Conclusion@#Blueberries have preventive effect on CCl4-induced hepatic fibrosis in rats, and its preventive mechanism may inhibit the expression and activation of NF-κBp65 in hepatocytes, thereby reducing TGFβ1- mediated production or activation.
ABSTRACT
Objective:To investigate the expression level of synaptophysin (Syn), tissue neuronal cell adhesion molecule 56 (CD56) and chromogranin A (CgA) in 92 primary esophageal small cell carcinoma (PESC) and to explore its repationship with clinicopathological features and clinical outcome. Methods:Immunohistochemical studies of CD56, CgA, and Syn were performed in 92 paraffin-embed-ded tissues with clinical-related information obtained from 500,000 esophageal and gastric cardia carcinoma databases established by Henan Key Laboratory for Esophageal Cancer Research of the First Affiliated Hospital of Zhengzhou University in Henan, China. Binary logistic regression was used to analyze the correlations of CgA, Syn, and CD56 expression with clinicopathological features. Kaplan-Mei-er survival analysis and Cox proportional hazards regression models were performed for univariate and multivariate survival analyses. Log-rank test was used to compare the difference in survival rates. Results:The CgA-positive expression rate in PESC at lower segment of esophagus (72.2%) was higher than those at the middle and lower segments (41.1%, 10.0%) (P=0.001). The expression level of CD56, CgA, and Syn was not correlated with gender (P=0.262, 0.998, 0.931), age (P=0.250, 0.998, 0.703), tumor invasion (P=0.253, 0.997, 0.061), and lymph node metastasis (P=0.767, 0.998, 0.613). Univariate analysis showed no survival influence in patients with and without lymph node metastasis (P=0.563). Multivariate survival analysis showed that patients with PESC mixed squamous cell car-cinoma (HR=2.58;95%Cl, 1.11-5.98) and higher CgA protein expression (HR=1.87;95%Cl, 1.02-3.43) exhibited a longer survival time than those with pure PESC and without CgA expression. Conclusion:Tissue CgA level was associated with tumor location in PESC. His-tological type and tissue CgA expression were independent important prognostic factors, and lymph node metastasis exerted no influ-ence on survival in PESC.
ABSTRACT
Objective:To elucidate the factors influencing the differences in the survival rates of esophageal squamous cell carcinoma (ESCC) patients between the rural and urban regions in China. Methods:A total of 36,723 ESCC patients derived from the clinical data-bases containing 500,000 esophageal and gastric cardia carcinoma cases (1973-2015) of the Henan Key Laboratory for Esophageal Can-cer Research of the First Affiliated Hospital, Zhengzhou University, were analyzed. Of these patients, 33,625 were from the rural re-gions (91.6%), comprising 20,906 male patients with an average age of 58.98 ± 8.71 years and 12,719 females with an average age of 59.59 ± 8.53 years. The remaining 3,098 were from the urban regions and composed of 2,089 male patients with an average age of 60.84±9.10 years and 1,009 females with an average age of 62.46 ± 9.14 years. All the patients underwent radical esophagectomy, de-tailed histopathological diagnosis, and TNM staging. Chi square test, Kaplan-Meier, Log-rank, and Cox proportional hazards regression model were used to analyze the differences between ESCC patients from rural regions and those from urban regions and among the risk factors in prognosis. Results:Kaplan-Meier and Log-rank analysis results showed that the ESCC patients from the rural regions had significantly higher overall survival than the urban patients (χ2=12.971, P=0.000). Further analysis showed that rural patients≥50 years old and diagnosed with stage IIa and IIb (middle stage) ESCC had higher survival rates than urban patients in males and females (male:χ2=16.188, P0.05). The results of Cox proportional hazards regression model analysis showed that age, gender, and TNM stages were independent risk factors for rural and urban ESCC patients. When the rural and urban ESCC patients were both considered, the Cox proportional hazards regression model analysis results showed that male ESCC patients≥50 years old, urban residence, and TNM stages were independent risk factors. Conclusion:Rural ESCC patients have significantly high-er overall survival than urban patients. Male, age of≥50 years old, urban residence, and TNM stages were independent risk factors for ESCC patient survival.
ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) is a common liver disease in clinical practice and has a complex pathogenesis. At present, the "two- or three-hit" theory is still widely acknowledged as the major pathogenesis of NAFLD. However, in recent years, the role of liver immunological inflammation in the development and progression of NAFLD has been taken more and more seriously. This article elaborates on the mechanism of liver immunological inflammation in the development and progression of NAFLD from the perspective of liver immunological inflammation.
ABSTRACT
Objective:To investigate the clinicopathological characteristics, treatments, and survival of patients with esophageal adeno-squamous carcinoma (EASC). Methods:A total of 494 patients with EASC were selected from the clinical information databases of 500, 000 cases with esophageal and gastric cardiac carcinomas in the Henan Key Laboratory for Esophageal Cancer Research. Among the 494 EASC cases, 361 were males with an average age of 61.47 ± 8.32 years, and 133 were females with an average age of 65.56 ± 8.06 years. SPSS 21.0 software was applied to determine the statistical differences among the different groups. A life-table method was also used to calculate the five-year survival rate. A linear regression model was used to analyze the correlation of changes at different peri-ods. Results:The incidence of EASC in our database was 0.196%(494/251707). EASC occurred predominantly in male patients (male:female=2.71:1.00). The peak age was within 60-69 years in both males and females (39.6%vs. 40.6%). Notably, the incidence of male patients showed a downward trend (R2=0.063), whereas that of female patients showed an upward trend (R2=0.004). The prevalence of EASC was obviously higher in low-incidence areas for esophageal cancer than in high-incidence areas (53.1%vs. 46.9%, P<0.001). Ac-cording to the TNM staging criteria for esophageal cancer, phases II and III patients comprised the majority of cases, which accounted for 40.8%(173/424). The positive lymph node metastasis rate was 47.0%(206/438), and the number of positive lymph node metasta-ses ranged within 1-2 (48.5%, 100/206). In addition, preoperative biopsy was performed in 467 cases, and more than half of the pa-tients (53.96%, 252/467) were diagnosed before the operation. Surgical resection was the predominant treatment method for EASC (88.8%, 419/472). Only 1.9%patients (9/472) underwent radiotherapy and chemotherapy. The five-year survival rate of male patients who were neither smoking nor drinking of alcohol was higher than that of male smokers (26.5%vs. 12.1%). In patients with stagesⅠ,Ⅱ, andⅢ+Ⅳcarcinomas with surgery as lone treatment, the three-year survival rates were 64.7%, 50.9%, and 48.5%, respectively. Correspondingly, these rates were 51.7%, 47.8%, and 33.1%after adjuvant radiotherapy and chemotherapy. Conclusion:EASC is a rare type of esophageal malignant tumor. The preoperative biopsy pathological diagnosis has high misdiagnosis rate. Smoking and drinking of alcohol can influence the prognosis of patients. In EASC patients, lymph node metastasis easily occurs, and a simple surgery is bet-ter than other cancer treatments.
ABSTRACT
Esophageal cancer is a unique malignant disease in China. A fundamental difference exists between the Chinese population and the western population on esophageal cancer in terms of epidemiology, histogenesis, and carcinogenic risk factors. Therefore, ap-plying the western academic achievements to Chinese is difficult. Thus, Chinese scientists have the responsibility to conquer esopha-geal cancer in China. This article reviews the progress of esophageal cancer focused on the molecular mechanism for interactions of ge-netic and environmental risk factors and human esophageal multistage carcinogenesis.
ABSTRACT
Objective:To analyze the clinicopathological characterization of primary esophageal benign tumor (EBT). Methods:A total of 1,058 EBTs were enrolled from 500,000 cases in an esophageal and cardiac tumor biological sample and clinical information data-base of Henan Key Laboratory for Esophageal Cancer Research (1973-2015) in the First Affiliated Hospital of Zhengzhou University. SPSS 21.0 software was applied for data analysis. Results:In this database, 1,058 cases with primary EBTs among the 249,246 esopha-geal tumor patients with detailed clinical and pathological information were identified with an incidence of 0.42%(1,058/249,246). A total of 544 patients were male with an average age of 50±11 years old, whereas 514 patients were female, with an average age of 52± 11 years old. Among the 10 types of EBTs, leiomyoma was the most common type (84.50%, 894/1,058), followed by papilloma (6.90%, 73/1058). Adenoma (0.38%, 4/1,058) was the rarest type. Leiomyoma, gastrointestinal stromal tumor, and neurofibroma mainly oc-curred in male patients. By contrast, lipoma, granulosa cell tumor, schwannoma, and hemangioma mainly occurred in female patients.All five cases of hamartoma occurred only in female patients. Given the incidence of≥50%as the common standard, the common EBT in sequence in young male patients was leiomyoma and gastrointestinal stromal tumor, whereas that in young female patients was granulosa cell tumor and lipoma. The common EBT in sequence in older male patients was papilloma, gastrointestinal stromal tumor, and leiomyoma, whereas that in older female patients was schwannoma, papilloma, leiomyoma, gastrointestinal stromal tumor, and hamartoma. Additionally, lipoma, hemangioma, neurofibroma, and adenoma in male patients and neurofibroma in female patients oc-curred in older patients. The different ages of patients with EBTs (P=0.034) and leiomyoma (P=0.004) had a statistical significance. In these EBTs, leiomyoma, papilloma, gastrointestinal stromal tumor, and schwannoma mainly occurred in the middle esophagus, where-as lipoma mainly occurred in the lower esophagus. The major treatment for EBT in the present study was surgery (57.54%, 492/855), which was followed by endoscopic resection (38.01%, 325/855) and others (4.45%, 38/855). Conclusion:The incidence of EBT is low, with a couple of different histological types. Gender, age, and predilection sites are different depending on the histological types of EBTs. Surgery and endoscopic resection are the major treatment methods.
