[Reclassification of flat type sudden deafness].

Objective: To reclassify the flat type sudden deafness according to the types of audiogram shape, and to explore the correlation between different pattern of hearing loss and prognosis. Methods: All of 1 024 patients with unilateral sudden deafness (492 males and 532 females, aged from 19 to 65 years, with an average age of 41.2 years old) admitted to 33 hospitals nationwide from August 2007 to October 2011 were divided into four types according to Chinese Guideline of Sudden Deafness(2015): low-frequency, high-frequency, flat and total deafness. Then, 402 patients with flat type sudden deafness were further divided into ascending type, descending type and consistent type according to the audiogram shapes. First, we compared the clinical characteristics and prognosis among these three subtypes of flat deafness, then compared the clinical characteristics and prognosis between ascending flat deafness and low-frequency deafness, descending flat deafness and high-frequency deafness, consistent flat deafness and total deafness, explored the factors related to the prognosis of flat deafness. SPSS 21.0 software, ANOVA, χ2 test, t-test and Logistic regression were used to analyze the data. Results: The cure rates of flat ascending, flat descending and flat consistent sudden deafness groups were 70.7%, 17.1% and 34.0% respectively, with a statistically significant difference (χ2=33.984, P<0.001); However, there was no significant difference in age, sex and affected side (all P>0.05). The independent related factors for the recovery of flat type sudden deafness were as follows: whether there was dizziness [OR=0.459; 95% confidence interval (CI): 0.271-0.777], the type of audiogram shape (OR=0.721; 95%CI: 0.530-0.981), and days from onset to therapy (OR=0.903, 95%CI: 0.835-0.978), all of which had P values<0.05. There was no significant difference in the cure rates between ascending flat sudden deafness and low-frequency descending sudden deafness, descending flat sudden deafness and high-frequency descending sudden deafness (all P>0.05). The pure tone average(PTA) of flat consistent sudden deafness and total deafness were (69.1±18.9) and (101.7±17.7) dB HL, respectively, with a statistically significant difference (t=20.890, P<0.001), and the cure rates were 34.0% and 14.5%, respectively, with a statistically significant difference (χ2=29.012, P<0.001). Conclusion: According to the audiogram shape, the flat type sudden deafness can be further divided into ascending flat sudden deafness, descending flat sudden deafness and consistent flat sudden deafness, which can more effectively evaluate the prognosis. The cure rate of ascending flat sudden deafness is similar to that of low-frequency sudden deafness, and the prognosis is well; The cure rate of descending flat sudden deafness is similar to that of high-frequency descending sudden deafness, and the prognosis is poor. The cure rate of consistent flat sudden deafness is higher than that of total deafness. PTA plays an important role in the prognosis of consistent flat sudden deafness and total deafness. Total deafness can be regarded as a single type of sudden deafness.

[The peripheral blood inflammatory markers in Ménière's disease patients with and without migraine].

Objective: To investigate the peripheral blood inflammatory markers including white blood cell count (WBC), monocytes, neutrophils, lymphocytes, platelets, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), high-density lipoprotein(HDL-C), low-density lipoprotein and fibrinogen (FIB) in Ménière's disease (MD) patients with and without migraine, and to explore the relationship between the inflammatory response with MD and migraine. Methods: The general physical condition, clinical manifestations, pure-tone audiometry, and peripheral blood inflammatory markers of 92 unilateral MD patients who were hospitalized in Peking University People's Hospital for surgical treatment from January 2017 to January 2021 were continuously collected. Meanwhile, 50 healthy controls matched with age and sex were included, and their general physical conditions and peripheral blood inflammatory markers were also collected. This study consisted of two parts. First, the differences in epidemical characteristics and peripheral blood inflammatory markers between MD patients and healthy controls were compared by univariate analysis. Second, all 92 MD patients were divided into two subgroups according to whether they were accompanied by migraine. The clinical characteristics and peripheral blood inflammatory markers of MD patients with and without migraine were compared by univariate analysis. Thereafter, binary Logistic regression was used to analyze the related factors of whether MD patients were accompanied with migraine. Results: Compared with the healthy control group, the peripheral blood WBC, neutrophils and FIB of MD patients were significantly increased (all P<0.05). Compared with MD patients without migraine, MD patients with migraine had higher female prevalence, longer disease history, lower low-frequency hearing threshold, higher frequency of vertigo attacks and higher HDL-C levels (all P<0.05), meanwhile, female, frequency of vestibular attacks and HDL-C were independent related factors of whether MD patients were accompanied with migraine. Conclusion: The occurrence of MD and migraine may be related to the inflammatory response. The level of anti-inflammatory factors in the blood of MD patients with migraine are higher, suggesting that the inflammatory response status of MD patients with and without migraine is different.

[Correlation analysis of incidence, season and temperature parameters of different types of sudden deafness].

Objective:The objective of this study was to investigate the correlation between the onset of different types of sudden sensorineural hearing loss（SSNHL） with temperature parameters and seasons. Method:We retrospectively reviewed the medical charts of 175 patients who were diagnosed as SSNHL, precisely collected the exact date and city of onset, confirmed the season, and obtained the meteorological data including maximum temperature（Tmax）, minimum temperature（Tmin）, mean temperature（T）, day-to-day change of mean temperature（ΔT）, and diurnal temperature range（Trange） at the same day, then analyzed the relation between season and temperature with the onset of different types of SSNHL. Result:There was a significant difference of Trange between different types of SSNHL（P=0.001）. Trange on the onset date of all-frequency SSNHL（including flat and profound type） was significantly higher than low and high frequency descending type（P=0.001, P<0.05 respectively）. Types of SSNHL had weak association with Trange groups（P=0.03, Cramer's V=0.220）. An increase of 1℃ in Trange increased the risk of flat type SSNHL by 23.9% and 16.5% compared with low and high frequency descending type, respectively, and for profound type, the risk was increased by 22.4% and 15.1%. No significant differences were observed between seasons and SSNHL types（P=0.666）. Conclusion:The incidence of different types of sudden sputum may be related to the worse temperature on the day, and has nothing to do with the disease season.

[The correlation between plasma fibrinogen level and different types of sudden sensorineural hearing loss].

Objective: To investigate the correlation between plasma fibrinogen level and the incidence of sudden hearing loss. Method: A total of 225 patients (age ranging from 18 to 70 years) with sudden sensorineural hearing loss(SSNHL) were selected. The disease onset was within 2 weeks. No patient received previous medical intervention. Depending on the types of auditory threshold curve, SSNHL was divided into low frequency descending type, high frequency descending type, flat desending type and total deafness type. Two hundred and twenty-nine cases with normal hearing and no inflammatory diseases in the same period was selected as control group. Fibrinogen level and Blood Routine Indexes were detected for the purpose of retrospective cohort study.Result: The levels of fibrinogen in SSNHL group(2.98±0.59) g/L were significantly higher than that in control group(2.66±0.36) g/L (P<0.01). According to the types of auditory threshold curve, SSNHL groups were divided into group A(55 cases, 24.44%), Group B(36 cases, 16.00%), Group C(43 cases,19.11%) and Group D(91 cases, 40.44%). The average fibrinogen levels before treatment were at(2.75±0.46)g/L, (3.16±0.61) g/L, (3.02±0.63) g/L and(3.03±0.63) g/L respectively. There was no significant difference in fibrinogen level(P=0.286) between group A and the control group. Fibrinogen levels of group B, group C and group D were significantly elevated compared to control group (P<0.01). Conclusion: The level of fibrinogen is not significantly correlated with development of sudden deafness of low frequency descending type. The incidence of high frequency descending type, flat descending type and profound deafness type are all correlated with the level of high fibrinogen at the onset of sudden deafness. The classification of sudden deafness based on audiogram curves could be of great significance for analysis of possible causes and selection of treatment options.

[Study on the effects of microRNA-203 on the invasion and apoptosis of laryngeal cancer cells via targeting LASP1].

Objective: To explore the role of microRNA-203 in laryngeal cancer and its underlying mechanism and clarify the relationship between microRNA-203 and LASP1.Method: microRNA-203 expression in laryngeal cancer tissues and paracancerous tissues was detected by quantitative real time-polymerase chain reaction（qRT-PCR）. The regulatory effects of microRNA-203 on invasion and apoptosis of laryngeal cancer cells were detected by Transwell assay and flow cytometry, respectively. Dual-luciferase reporter gene assay was performed to access the binding condition of microRNA-203 and LASP1. Both mRNA and protein levels of LASP1 in laryngeal cancer cells were detected after transfection with microRNA-203 mimic or microRNA-203 inhibitor by qRT-PCR and Western blot. Rescue experiments were finally performed to detect whether microRNA-203 regulates laryngeal cancer development via targeting LASP1. Result: microRNA-203 was lowly expressed in laryngeal cancer tissues and cell lines.Knockdown of microRNA-203 in Hep-2 cells can promote the invasiveness and inhibit apoptosis of laryngeal cancer cells. Subsequently,LASP1 was predicted to be the target gene of microRNA-203，which was further verified by dual-luciferase reporter gene assay.LASP1 expression was negatively regulated by microRNA-203. Furthermore，rescue experiments showed that microRNA-203 regulates invasion and apoptosis of laryngeal cancer cells via targeting LASP1. Conclusion： Low expression of microRNA-203 could promote the invasion and inhibit apoptosis of laryngeal cancer cells viainhibiting LASP1. microRNA-203 and LASP1 both play a very important role in the development of laryngeal cancer..

[Study on the relationship between age-related hearing loss and cognitive impairment].

Objective: To investigate the correlation between age-related hearing loss and cognitive impairment. Methods: 201 elderly patients, who were admitted to the Department of Otorhinolaryngology of Peking University People's Hospital from March 1, 2017 to March 31, 2017, were evaluated with hearing screening and the Montreal Cognitive Assessment Scale. Among them, 101 were female and 100 were male, aged 60-90 years old. Taking the cognitive level as the dependent variable, and taking the age, sex, education, occupation, marital status, residence, and average hearing loss (average hearing threshold of 500, 1 000, 2 000, and 4 000 Hz), as well as the length of conscious hearing loss as the independent variables, the single factor analysis and multivariate linear regression analysis were used to screen the main factors affecting the cognitive level of the elderly. Results: Of the 201 elderly patients, 39 had normal hearing, 65 had mild hearing loss, 80 had moderate hearing loss, 16 had severe hearing loss, and 1 had profound hearing loss. The average degree of hearing loss was the influencing factor of cognitive impairment, and it mainly affected the directional force and abstract ability in the cognitive domains (P<0.05); The age, self-reported hearing loss, years of education, marital status, past ear diseases, and hypertension were relatively independent factors that affected the cognitive level(P<0.05). Conclusions: Age-related hearing loss is the risk factor for the cognitive impairment, especially for abstraction and orientation, in the elderly. The self-reported hearing loss is an independent risk factor for cognitive impairment.

[The study about the role of laryngopharyngeal reflux for the hemorrhage after tonsillectomy].

Objective:To assess the role of LPR in the development of complications, such as hemorrhage, following tonsillectomy in adult patients. We want to provide a guidence for future clinical practice.Method:Totally 70 adult patients who had indication of tonsillectomy were recruited and divided into two groups, the laryngopharyngeal reflux (LPR) group and the control group, which were identified by the results of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). We observed and compared the postoperative complications of the two groups and analyzed the role of LPR.Result:All the patients complained pain after surgery. The duration of the pain in LPR group was much longer than that of control group. The mean body temperature in both groups was not significantly different (P＞0.05). There were six cases of bleeding in the LPR group, while only one case of bleeding occurred in the control group. The difference was statistically significant (P<0.05). There were no cases of infection or pulmonary complications in both groups. All patients were discharged successfully.Conclusion:LPR is closely related to the complications following tonsillectomy.

MicroRNA-203 inhibits invasion and induces apoptosis of laryngeal cancer cells via targeting LASP1.

OBJECTIVE: To explore the role of microRNA-203 in laryngeal cancer and its underlying mechanism in regulating cell invasion and apoptosis. PATIENTS AND METHODS: MicroRNA-203 expression in laryngeal cancer tissues and paracancerous tissues was detected by quantitative real time-polymerase chain reaction (qRT-PCR). The regulatory effects of microRNA-203 on the invasion and apoptosis of laryngeal cancer cells were detected by transwell assay and flow cytometry, respectively. Dual-Luciferase reporter gene assay was performed to access the binding condition of microRNA-203 and LASP1. Both mRNA and protein levels of LASP1 in laryngeal cancer cells were detected after transfection with microRNA-203 mimic or microRNA-203 inhibitor by qRT-PCR and Western blot, respectively. Rescue experiments were finally performed to detect whether microRNA-203 regulates laryngeal cancer development via targeting LASP1. RESULTS: MicroRNA-203 was lowly expressed in laryngeal cancer tissues and cell lines. MicroRNA-203 knockdown in Hep-2 cells can promote the invasion and inhibit the apoptosis of laryngeal cancer cells. Subsequently, LASP1 was predicted to be the target gene of microRNA-203, which was further verified by the Dual-Luciferase reporter gene assay. LASP1 expression was negatively regulated by microRNA-203. Furthermore, rescue experiments showed that the regulatory effects of microRNA-203 on the invasion and apoptosis of laryngeal cancer cells were reversed by LASP1. CONCLUSIONS: We showed that lowly expressed microRNA-203 could promote the invasion and inhibit apoptosis of laryngeal cancer cells via inhibiting LASP1.

The role of Parkin protein in cardiac function and ventricular remodeling in myocardial infarction rats.

OBJECTIVE: This study aims to explore the role and the mechanism of Parkin protein in cardiac function and ventricular remodeling in myocardial infarction (MI) rats, and to provide a new sight for the treatment of myocardial infarction. MATERIALS AND METHODS: Fifty Sprague- Dawley (SD) male rats were randomly divided into 5 groups: sham operation group (Sham group), model group (MI group), low-dose Parkin group (L-Parkin group), middle-dose Parkin group (M-Parkin group) and high-dose Parkin group (H-Parkin group). The rat model of myocardial infarction was established by ligation of the anterior descending branch. Small animal ultrasound was used to measure cardiac function. The myocardial infarct size was observed by triphenyltetrazolium chloride (TTC) staining. The pathological changes of myocardial tissues were observed by hematoxylin-eosin (HE) staining. The myocardial cell apoptosis was detected by TUNEL assay. The mRNA expression of matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9), tissue inhibitor of matrix metalloproteinase 1 (TIMP1), tissue inhibitor of matrix metalloproteinase 2 (TIMP2) were detected by qRT-PCR. The expression of Parkin protein in myocardial tissue of rats was detected by Western-blot. RESULTS: Compared with MI group, left ventricular end-systolic volume (LVESV) and left ventricular end-diastolic volume (LVEDV) in Parkin overexpressing group were significantly decreased (p<0.05), while the value of left ventricular short axis shortening (FS) and left ventricular ejection fraction (EF %) in Parkin overexpression group were significantly increased (p<0.05). Overexpression of Parkin improved abnormal structure of myocardial tissue, reduced the size of myocardial infarct, made the arrangement of myocardium fibers more neatly and made the stain of myocardial cells more uniformly. Apoptosis index (AI) values were significantly decreased (p<0.05), and MMP2, MMP9, TIMP1 and TIMP2 mRNA levels were significantly decreased (p<0.05), while Parkin protein expression was significantly elevated in a dose-dependent manner (p<0.05). CONCLUSIONS: After treatment with Parkin in myocardial infarction rats, the relevant mRNA levels decreased, the number of apoptotic cells decreased, the myocardial fiber morphology returned to normal, the myocardial infarct size decreased, and the cardiac function of rats improved. Therefore, Parkin therapy plays an active role in cardiac function and ventricular remodeling in myocardial infarction rats.

[Correlation between the changes of fibrinogen and the treatment effect of all-frequency sudden deafness].

Objective: To analyze the correlation between the changes of fibrinogen and the treatment effect of all-frequency sudden deafness, and to explore the individualized treatment strategy for the use of Batroxobin. Methods: Patients with all-frequency sudden deafness who were admitted to Department of Otorhinolaryngology, People's Hospital of Peking University, from January 2010 to September 2016 were selected. All patients were given standard treatment and regular use of Batroxobin. Value of fibrinogen on D1 (before treatment) / D3 / D7 (±1) and D14 (±2) were recorded, at the same time, the correlation between the changes of fibrinogen and prognosis of all-frequency sudden deafness by the audiograms of onset and after-treatment of all patients were analyzed. Independent t-test was used to analyze normal distributed measurement data and chi square linear trend test was used to analyze the curative effect of different fibrinogen groups. Results: A total of 148 patients were included, the outcomes were worst when the patient's fibrinogen was below 2 g/L or above 4 g/L before treatment, ineffective rate were both 50%. The fibrinogen was lowest when the treatment came to the third day. Normally, the patient's prognosis was best when this value waved between 0.7 and 0.9 g/L, with a total effective rate between 73.9% and 83.3%. The fibrinogen value of the 7th day was a good indicator of the outcome, and Fib7 value was significant lower in patients of effective group than ineffective ones ((1.25±0.37)g/L vs (1.38±0.35) g/L, t=-0.27, P=0.04). Patients found a best recovery when Fib7 was below 1 g/L, and the higher the Fib7 value, the higher the inefficiency (χ(2)=7.55, P=0.01). Batroxobin showed safety during the treatment and found no complications. Conclusion: The change of fibrinogen in the process of all-frequency sudden deafness is closely related to the curative effect.

GDF11 does not improve the palmitate induced insulin resistance in C2C12.

OBJECTIVE: GDF11 (Growth Differentiation factor 11) has been reported to rejuvenate skeletal muscle, heart and brain in aged mice, and the aged skeletal muscle is closely related to insulin resistance. We wondered whether GDF11 has an effect on skeletal muscle insulin resistance. MATERIALS AND METHODS: High fat diet induced obese mice with insulin resistance were established in vivo. Palmitate-induced insulin resistance in C2C12 myotubes was established in vitro. The mRNA expression of GDF11, GLUT4, IRS-1 (insulin receptor substrate-1) and PGC-1α (peroxisome proliferator-activated receptor-gamma coactivator 1) were tested by reverse transcriptase-polymerase chain reaction (RT-PCR). The protein level of GDF11 and PGC-1α were detected by Western blot. The glucose uptake was measured by 2NBDG uptake assay. RESULTS: In high fat diet induced obese mice, both serum level of GDF11 and the expression of GDF11 in skeletal muscle decreased. Similarly, the expression of GDF11 also reduced in palmitate-treated C2C12 myotubes. In vitro, the glucose uptake and the expression of GLUT4, IRS-1 and PGC-1α significantly decreased after palmitate intervention, but GDF11 treatment did not reverse the reduction of glucose uptake and the expression of GLUT4, IRS-1 and PGC-1α in C2C12 myotubes. CONCLUSIONS: We firstly confirmed that the expression of GDF11 decreased both in the skeletal muscle of obese mice and palmitate-treated myotubes, but supplementation GDF11 does not ameliorate the palmitate-induced insulin resistance in C2C12 myotubes.

HDAC Inhibitor Oxamflatin Induces Morphological Changes and has Strong Cytostatic Effects in Ovarian Cancer Cell Lines.

Ovarian epithelial carcinoma is the leading cause of deaths from gynecologic malignancy. New reagents with therapeutic potentials against ovarian cancer, especially the drug-resistant cases, are required for better treatment of ovarian cancer patients. Epigenetic events such as changes in DNA methylation and histone modification, through their effects on DNA-protein interaction, chromatin conformation, and gene expression, affect cell function, cancer behavior, clinical manifestations, and outcomes. Previous studies have shown that histone deacetylase (HDAC) inhibitors have strong cytostatic and apoptotic activities in hematologic and some solid cancer cells. Oxamflatin, a compound containing the aromatic sulfonamide and hydroxamic acid groups, is known to be a potent HDAC inhibitor capable of inhibiting the growth of mouse and human cancer cell lines. In this study we found that oxamflatin in the nM range induced morphological changes in OVCAR-5 and SKOV-3 ovarian cancer cell lines. Treatment with oxamflatin also led to decreased cell viability. Moreover, results of BrdU incorporation assay, cell counting, and Ki-67 immunostaining indicated that oxamflatin was able to significantly inhibit DNA synthesis and cell proliferation. Using real-time PCR and Western blot analyses we demonstrated that oxamflatin was capable of downregulating the expression of c-Myc, CDK4, E2F1, and the phosphorylation levels of Rb protein, but upregulating p21. These findings pave the way to examine if oxamflatin along with or in combination with other reagents could deliver anticancer effects against ovarian cancers in vivo.

Objective:To explore the pathogenesis of tinnitus.Method:Retrospective analysis of 192 patients with sudden deafness was done with the characteristics.Charactier of tinnitus and the factors that may affect tinnitus.Result:The intense of tinnitus is related with sex,χ²=14.704,P<0.01,and with age increased,the difference was more significant.The intense of tinnitus has not significant difference between age group with 45 years old(χ² =6.515,P>0.05) and the classification of sudden deafness and the degree of hearing loss(χ²=7.783,P>0.05,χ²=17.374,P>0.05).Conclusion:Tinnitus was the protection mechanism of the body,and the intensity was irrelevant to hearing loss.On one hand,there may be different modulate systems between different individual,on the other hand,women over 45 years old were more suffered from the severe tinnitus.

[The reclassification of sudden deafness].

Objective:Reclassified the total deafness and flat type of sudden deafness,identified the relationship between new classification and hearing prognosis.Method:To analyze 192 cases of patients with sudden deafness,especially for 159 cases of flat type and total deafness patients for further curve type classification,classified as rise,decline and consistent,analysis the possible factors with hearing in multiple factors using regression analysis.Result:According to age group of 45 years old,P>0.05,the difference has not statistically significant;Course of the disease according to the 0-7 days and 14 days more,P<0.01,OR=4.291;8-14 days and 14 days,P<0.05,OR=2.983;According to the flat type and total deafness grouping,P<0.05,OR=0.409;According to the curve type of deafness,the difference between rise type and total deafness was significant,P<0.01,OR=9.692;Decline type,consistent type compared to total deafness type,there is no statistically significant difference,P>0.05.Conclusion:According to the pathogenesis of classification,sudden deafness can be divided into rise type,decline type and consistent type.The pathogenesis of rise type may be different degree of hydrops of inner ear.Decline type may be hair cell damage,and consistent type may be related to the damage of vascular stria and potential labyrinthitis,prognosis is poorer.

Autophagy prevents irradiation injury and maintains stemness through decreasing ROS generation in mesenchymal stem cells.

Stem cells were characterized by their stemness: self-renewal and pluripotency. Mesenchymal stem cells (MSCs) are a unique type of adult stem cells that have been proven to be involved in tissue repair, immunoloregulation and tumorigenesis. Irradiation is a well-known factor that leads to functional obstacle in stem cells. However, the mechanism of stemness maintenance in human MSCs exposed to irradiation remains unknown. We demonstrated that irradiation could induce reactive oxygen species (ROS) accumulation that resulted in DNA damage and stemness injury in MSCs. Autophagy induced by starvation or rapamycin can reduce ROS accumulation-associated DNA damage and maintain stemness in MSCs. Further, inhibition of autophagy leads to augment of ROS accumulation and DNA damage, which results in the loss of stemness in MSCs. Our results indicate that autophagy may have an important role in protecting stemness of MSCs from irradiation injury.

Paradoxical role of autophagy in the dysplastic and tumor-forming stages of hepatocarcinoma development in rats.

Many reports have shown that autophagy has a role as both a promoter and inhibitor in tumor development. However, the mechanism of this paradox is unknown. Tumor development is a multistep process. Therefore, we investigated whether the role of autophagy in hepatocarcinoma formation depended on the stage of tumor development. Based on our results, autophagy inhibition by chloroquine had a tumor-promotive effect in the rat model with N-diethylnitrosamine-induced hepatocarcinogenesis in its dysplastic stage (Ds) and a tumor-suppressive effect in its tumor-forming stage (Ts). In the Ds, autophagy inhibition enhanced cell proliferation, DNA damage and inflammatory cytokines expression in liver. These changes were dependent on the upregulation of reactive oxygen species (ROS) that was resulted from autophagy inhibition, and ultimately accelerated the process of hepatocarcinogenesis. However, in the Ts, autophagy inhibition restrained tumor formation by decreasing tumor cell survival and proliferation. In this stage, autophagy inhibition led to excessive ROS accumulation in the tumor, which promoted cell apoptosis, and prominently suppressed tumor cell metabolism. Taken together, our data suggested that autophagy suppressed hepatocarcinogenesis in the Ds by protecting normal cell stability and promoted hepatocarcinogenesis in the Ts by supporting tumor cells growth. Autophagy always had a role as a protector throughout the process of hepatocarcinoma development.
