ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. At present, hepatectomy is one of the most frequent therapeutic options, whereas the high postoperative recurrence rate severely affects the long-term survival of HCC patients. Therefore, it is urgent to choose appropriate therapeutic regime to treat the recurrence of HCC to improve the long-term survival of HCC patients. Surgical treatment is an efficacious treatment for recurrent HCC, including re-hepatectomy, salvage liver transplantation and radiofrequency ablation. Currently, individualized treatment is recommended for postoperative recurrence of HCC. The selection of treatment should be conducted based on the tumor conditions after the first hepatectomy, the characteristics of recurrent tumors, baseline data of patients and recurrence time, etc., aiming to formulate appropriate treatment regimes for patients. In this article, these surgical regimes were reviewed and compared to explore appropriate surgical schemes for postoperative recurrence of HCC, aiming to provide reference for prolonging the survival of HCC patients.

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

Objective:To evaluate the relationship between phosphorylation of Tau protein and apolipoprotein E (ApoE) containing 18 kDa fragments and investigate the mechanism of neuronal damage induced by sevoflurane.Methods:Primary neurons (ApoE3 and ApoE2 genotypes, 24 dishes for each genotype) of fetal mice cultured until the 5th day were divided into 4 groups ( n=12 each) using a random number table method: ApoE3 control group (A3C group), ApoE3 sevoflurane group (A3S group), ApoE2 control group (A2C group) and ApoE2 sevoflurane group (A2S group). Neurons were treated with 21% oxygen + 5% carbon dioxide + 4.1% sevoflurane for 4 h in A3S and A2S groups, while the neurons were only treated with 21% oxygen + 5% carbon dioxide in A3C and A2C groups.The cell proteins were then extracted to detect the expression of full-length ApoE and ApoE, AT8 and PHF1 containing 18 kDa fragments (by Western blot), expression of ApoE mRNA (by real-time polymerase chain reaction), and concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in the supernatant (by enzyme-linked immunosorbent assay). Results:Compared with A2C group, the expression of ApoE mRNA and full-length ApoE in neurons was up-regulated ( P<0.05), and no significant change was found in the expression of AT8 and PHF1 and concentrations of TNF-α and IL-6 in the supernatant in A2S group ( P>0.05). Compared with A3C group, the expression of ApoE mRNA, full-length ApoE, and ApoE, AT8 and PHF1 containing 18 kDa fragments was up-regulated, and the concentrations of TNF-α and IL-6 in the supernatant were increased in A3S group ( P<0.05). Conclusion:Sevoflurane may promote phosphorylation of Tau proteins and increase inflammatory responses through up-regulating the expression of ApoE containing 18 kDa fragments, thus leading to neuronal damage.

ABSTRACT

Objective:To evaluate the effect of acetaminophen on sepsis-associated encephalopathy (SAE) in mice and the relationship with ferroptosis.Methods:A total of 160 clean-grade healthy adult male C57BL/6J mice, aged 6 weeks, weighing 22-24 g, were divided into 4 groups ( n=40 each) using a random number table method: sham operation group (Sham group), sham operation+ acetaminophen group (Sham+ APAP group), SAE group and SAE+ acetaminophen group (SAE+ APAP group). The model of SAE was established by cecal ligation and puncture in anesthetized mice.Acetaminophen 100 mg/kg was intraperitoneally injected at 1 h before the model was established in group Sham+ APAP and group SAE+ APAP.The postoperative 7-day survival rate was recorded.At 24 h after operation, brain tissues were taken for examination of the pathological changes of neurons in hippocampal CA1 region.At 24 h after establishment of the model, ultrastructure was observed with a transmission electron microscope, the contents of reactive oxygen species (ROS), malondialdehyde (MDA) and glutathione (GSH) in hippocampus were determined by colorimetry, and the expression of glutathione peroxidase (GPX4), cystine/glutamate antiporter (xCT) and 4-hydroxy-2-nonenal (4-HNE) was determined by Western blot. Results:Compared with group Sham, the postoperative 7-day survival rate of mice was significantly decreased, contents of ROS and MDA in hippocampus were increased, GSH content in hippocampus was decreased and expression of GPX4 and xCT was down-regulated in SAE and SAE+ APAP groups, 4-HNE expression was up-regulated in group SAE ( P<0.05), and no significant change was found in the parameters mentioned above in group Sham+ APAP ( P>0.05). Compared with group SAE, the postoperative 7-day survival rate of mice was significantly increased, contents of ROS and MDA in hippocampus were decreased, GSH content in hippocampus was increased, expression of GPX4 and xCT was up-regulated and expression of 4-HNE was down-regulated in group SAE+ APAP ( P<0.05). The pathological changes in hippocampal CA1 region and damage to ultrastructure of hippocampal tissue were significantly attenuated in group SAE+ APAP as compared with group SAE. Conclusion:Acetaminophen can effectively alleviate SAE, and the mechanism is related to inhibiting ferroptosis in mice.

ABSTRACT

Objective:To investigate the effect of withdrawal time on postpartum liver function in pregnant women receiving tenofovir disoproxil fumarate (TDF) therapy for blocking mother-to-child transmission of HBV.Methods:A prospective study was conducted in Hangzhou First People’s Hospital from June 2016 to August 2018. A total of 84 pregnant women with HBsAg and HBeAg positive were enrolled and divided into two groups according to simple randomized grouping method with 42 cases in each group. In group A TDF was withdrawn immediately after delivery and in group B TDF was withdrawn 12 weeks after delivery. Finally, 66 patients completed the follow-up for 24 weeks postpartum, 35 cases in group A and 31 cases in group B. All patients were administered TDF from week 24-28 of pregnancy. HBV DNA loads and ALT levels were regularly measured and compared. Multivariate logistic regression was used to explore the risk factors of postpartum ALT flare. SPSS 26.0 statistical software was used for statistical processing.Results:Compared with the baseline levels, the HBV DNA loads at 16 weeks postpartum had no significant changes in both groups( Z=-0.742 and -1.891, both P>0.05). Postpartum ALT flare was observed in 21 of the 66 patients, 9 cases (25.71%, 9/35) in group A, and 12 cases (38.71%, 12/31) in group B ( χ2=1.280, P>0.05); and there was no significant difference in the severity of postpartum ALT flare between the two groups ( χ2=0.527, P>0.05). Binary logistic regression analysis showed that increased ALT level during pregnancy was an independent risk factor of postpartum ALT flare ( OR=13.75, 95% CI 1.49-126.85, P<0.05). Conclusions:When TDF was used for preventing mother-to-child HBV transmission, withdrawal at different times after delivery had no effect on postpartum liver function. ALT flare during pregnancy is a risk factor for postpartum ALT flare, so TDF should be discontinued carefully and liver function should be closely monitored postpartum for such patients.

ABSTRACT

OBJECTIVE To evaluate the effects of flavonoids from Xindakang (Hippophae Fructus flavone) on myo?cardial systolic and diastolic functions of isolated frog hearts and explore the possible mechanism, and provide experi?mental basis for improving the effect and efficacy of Xindakang on cardiac function. METHODS The isolated frog heart perfusion specimens were prepared by Yagi's method, and the effects of different concentrations of Xindakang on myo?cardial contractility (0.0125, 0.025, 0.05, 0.1 and 0.2 g·L-1), heart rate and cardiac output of isolated frog heart were stud?ied. Acetylcholine, atropine and epinephrine were administered successively to analyze the effects of Xindakang on car?diac systolic function of isolated frogs under the action of different drugs, and compared with propranolol. The effect of extracellular calcium ion concentration on the action of Xindakang was studied by using low calcium concentration, high cal?cium concentration and normal Ren's solution. To study the effect and possible mechanism of Xindakang on cardiac systolic function of frog. RESULTS The concentration of Xindakang in the range of 0.0125-0.1 g·L-1 could weaken the contractility of isolated frog heart and increase the concentration of Xindakang. The inhibitory effect of Xindakang on con?tractility of isolated frog heart was enhanced, and showed obvious dose-effect relationship. Cardiac output was signifi?cantly decreased by Xindakang (P<0.01), slow heart rate (P<0.05); M receptor blocker atropine could not antagonize the contractile effect of Xindakang, and Xindakang could not completely antagonize the contractile effect of adrenalin. Xindakang could inhibit the isolated frog heart in low calcium concentration, high calcium concentration and normal Ren's solution, and increased with the increase of extracellular calcium concentration (P<0.01). CONCLUSION Xinda?kang has inhibitory effect on isolated frog heart, which may be achieved by blocking the calcium channel on myocardial cell membrane and reducing the calcium concentration in myocardial cells.

ABSTRACT

METHODS@#The clinical data of 53 COVID-19 patients were collected from a single center in Wuhan from February 8, 2020 to March 25, 2020. The patients were divided into severe type group (38 patients) and critical type group (15 patients). The clinical characteristics, indexes of liver function, coagulation function and inflammatory markers were analyzed retrospectively. According to the degree of abnormal liver function in the process of diagnosis and treatment, the patients were divided into three groups: combined liver injury, mild abnormal liver function and normal liver function group. Statistical analysis was performed by using Student t test, Mann-Whitney U test, Kruskal-Wallis test and Chi-square test.@*RESULTS@#Among the 53 patients, 29 were male (54.7%) and 24 were female (45.3%), the median age was 57(27-80) years old. The time from onset to admission was (11.5±7.7) days. The levels of AST, TBIL, DBIL, ALP, GGT, LDH, D-dimer, PCT and hsCRP in critical patients were higher than those in severe patients (P<0.05). The levels of Alb in critical patients was lower than those in severe patients (P<0.05). Among the 53 patients, 34 (64%) patients showed abnormal elevation of ALT, AST or TBIL, while 4 (7.5%) patients showed the criteria of COVID-19 with liver injury. After the patients were grouping according to the degree of liver dysfunction, the levels of ALP, GGT and D-dimer of the patients in the liver injury group were significantly higher than those in the normal liver function group, D-dimer levels of the patients in the liver injury group was significantly higher than those in the mild abnormal liver function group, while the levels of ALP and GGT in the mild abnormal liver function group were significantly higher than those in the normal liver function group, and the differences were statistically significant(P<0.05).@*CONCLUSION@#In this group, the patients with COVID-19 severe/critical type have a certain proportion of liver injury accompanied by significantly increased D-dimer levels, critical type patients have more severe liver function and coagulation dysfunction, which may promote the progression of COVID-19.

ABSTRACT

To improve the diagnostic efficiency of prostate cancer (PCa) and reduce unnecessary biopsies, we defined and analyzed the diagnostic efficiency of peripheral zone prostate-specific antigen (PSA) density (PZ-PSAD). Patients who underwent systematic 12-core prostate biopsies in Shanghai General Hospital (Shanghai, China) between January 2012 and January 2018 were retrospectively identified (n = 529). Another group of patients with benign prostatic hyperplasia (n = 100) were randomly preselected to obtain the PSA density of the non-PCa cohort (N-PSAD). Prostate volumes and transition zone volumes were measured using multiparameter magnetic resonance imaging (mpMRI) and were combined with PSA and N-PSAD to obtain the PZ-PSAD from a specific algorithm. Receiver operating characteristic (ROC) curve analysis was used to assess the PCa detection efficiency in patients stratified by PSA level, and the area under the ROC curve (AUC) of PZ-PSAD was higher than that of PSA, PSA density (PSAD), and transition zone PSA density (TZ-PSAD). PZ-PSAD could amend the diagnosis for more than half of the patients with inaccurate transrectal ultrasonography (TRUS) and mpMRI results. When TRUS and mpMRI findings were ambiguous to predict PCa (PIRADS score ≤3), PZ-PSAD could increase the positive rate of biopsy from 21.7% to 54.7%, and help 63.8% (150/235) of patients avoid unnecessary prostate biopsy. In patients whose PSA was 4.0-10.0 ng ml

ABSTRACT

Objective@#To understand the prevalence of HIV (human immunodeficiency virus) testing and associated factors among sexual active college students in Zhuhai City.@*Methods@#From November to December, 2019, an anonymous electronic questionnaire was administered among 12 235 students in six colleges and universities in Zhuhai City by multistage sampling. A total of 1 789 college students ever had sex were selected. Pearsons Chisquare test and nonconditional Logistic regression model were applied to analyze the factors associated with uptake of HIV testing.@*Results@#Among these students ever had sex, 7.55% (135/1 789) had been tested for HIV mainly through hospitals (71.85%). The main reasons for testing were regular testing (50.37%) and intending to know their infection status (23.70%). Multivariable Logistic regression showed that homosexual individuals (OR=4.62, 95%CI=1.07-19.95) and those who had heterosexual commercial sex in the past year (OR=3.77, 95%CI=1.96-7.26) were more likely to test for HIV, while female (OR=0.41, 95%CI=0.24-0.69) were less likely to test for HIV.@*Conclusion@#The proportion of HIV testing was low among sexual active college students in Zhuhai City. Interventions should be tailored including strengthening the HIV testing propaganda education and enhancing students awareness of HIV testing, and the influencing factors such as gender, sexual orientation and commercial sexual behavior should be taken into consideration, so as to improve the HIV testing coverage of this population.

ABSTRACT

Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

ABSTRACT

Objective:To evaluate iron metabolism disorders in sepsis patients and explore the effect of iron deficiency on mortality.Methods:Patients ( n=130) who were admitted to the emergency intensive care unit (ICU) of the First Affiliated Hospital of Dalian Medical University from September 2016 to July 2018 and met the diagnostic criteria of Sepsis 3.0 were selected, and sex- and age-matched healthy volunteers ( n=20) were enrolled as a control group. Peripheral venous blood samples were collected in sepsis patients on day 1, 3 and 7 after admission, or in the healthy volunteers upon enrollment, to detect iron metabolism-related indicators and interleukin-6 (IL-6); the Sequential Organ Failure Assessment (SOFA) score was calculated upon hospital admission. Iron metabolism-related indicators were compared between the groups; the correlation of plasma iron with hemoglobin, hepcidin, ferritin, IL-6, sTFR/log ferritin and the ability of plasma iron to predict 28-day death of sepsis patients were analyzed. Results:Sepsis patients developed significant anemia on day 3 after admission; plasma iron, transferrin, iron saturation, total iron binding capacity and unsaturated iron binding capacity in the first week of admission were significantly lower than those in the control group; distribution width of red blood cells, ferritin, IL-6, hepcidin and soluble transferrin receptor were significantly higher than those in the control group. Distribution width of red blood cells, ferritin and hepcidin on day 3 and 7 after admission, and plasma iron and iron saturation on day 7 after admission were significantly higher than those on day 1. However, total iron binding capacity and unsaturated iron binding power on day 7, and sTFR/log ferritin on day 3 were significantly lower than those on day 1. Patients in the survival and non-survivor groups in the first week of admission had significant anemia on day 3 and 7, but the anemia was worse in the non-survivor group. Transferrin, total iron binding capacity, and unsaturated iron binding capacity in the non-survivor group in the first week of admission, and plasma iron in the non-survivor group on day 3 and 7, were significantly lower than those in the survival group. Ferritin, IL-6 and hepcidin in the non-survivor group in the first week of admission, and iron saturation on day 7 were significantly higher than those in the survival group. Spearman correlation analysis showed that plasma iron was negatively correlated with IL-6 ( r=-0.391, P<0.01), ferritin ( r=-0.293, P=0.001) and hepcidin ( r=-0.209, P=0.017), but not with hemoglobin ( r=0.005, P=0.958). The area under the operation curve (AUC) for plasma iron for predicting 28-day mortality in sepsis patients was 0.524 (95% CI: 0.416-0.631, P=0.656). Conclusions:Sepsis patients have significant anemia and iron metabolism disorders in the early stage, while non-survival patients are more severe. Reduced plasma iron level has no capacity to predict 28-day mortality of sepsis patients. In addition, decreased plasma iron level is not related to decreased hemoglobin, and thus iron supplementation should be cautious in sepsis patients.

ABSTRACT

Objective:To evaluate the effects of wearing N95 mask on the quality of chest compression and fatigue.Methods:A total of 80 participants from Zhongnan Hospital with basic life support (BLS) certification conferred by American Heart Association (AHA) within two years were enrolled. After reviewing the key points of cardiopulmonary resuscitation (CPR) and grasping the operation on the manikin, they were randomized (random number) into two groups: wearing surgical masks (SM group, n=40) and wearing N95 masks (N95 group, n=40) during CPR. Each participant performed a 2-minute chest compression-only CPR on the manikin. Participants' height, body weight, Borg scores and physiological parameters before and after CPR were recorded. The quality of chest compression (including compression depth, compression rate, adequate depth proportions, adequate rate proportions, hand position and complete chest recoil) were recorded by Laerdal QCPR ? software. Student's t test and Mann-Whitney test were used to compare the differences of chest compression quality indexes between the two groups. Results:Compared with the SM group, participants in the N95 group had significantly increased median of Borg scores after CPR (16 vs 14, P=0.027), and decreased quality of chest compression, including the decline in compression depth (mean 47 mm vs 52 mm, P=0.020), compression rate (107 times/min vs 118 times/min, P=0.004), complete chest recoil rate (89.8% vs 98.1%, P=0.046), adequate depth proportions (67.4% vs 89.6%, P<0.01) and adequate rate proportions (60.6% vs 74.8%, P<0.01). Conclusions:Wearing N95 masks during CPR decreases the quality of chest compression and aggravates rescuers’ fatigue. Therefore, it is necessary to exchange rescuers more frequently to ensure the quality of chest compression when wearing N95 masks.
