Objective:To analyze the characteristics of long non-coding RNA (lncRNA) expression in nonalcoholic fatty liver disease (NAFLD).Methods:lncRNA-mRNA microarray was conducted on the liver tissue samples from 10 patients with simple gallbladder stone (5 NAFLD liver samples and 5 normal liver samples),and the differentially expressed lncRNA was analyzed by bioinformatics technology.Results:Compared with the normal liver samples,there were abnormal expression of 1 735 lncRNAs and 1 485 mRNAs in NAFLD liver samples.Among them,535 lncRNAs and 760 mRNAs were up-regulated,1 200 lncRNAs and 725 mRNAs were down-regulated.Conclusion:Compared with normal liver,the expression oflncRNA in NAFLD tissues is obviously abnormal.These lncRNAs may play an important role in the occurrence and development of NAFLD.

Objective To investigate the treatment and prognosis of patients with papillary thyroid microcarcinoma. Methods The clinical and following-up data of 124 patients with papillary thyroid microcarcinoma treated at the Department of Head and Neck Surgery of Cancer Centre, SUN Yat-sen University from Jan 1990 to Dec 1999 were analyzed retrospectively for mortality and survival rate ( KaplanMeier). A multivariate analysis was performed in these patients by Cox proportional hazard model. Results The overall 10-year and 15-year survival rate of all 124 patients with papillary thyroid microcarcinoma were 94.9% and 92.5% respectively. The univariate analysis showed the prognostic factors significantly influencing the survival of patients included age (being worse for those of 35 years and older) at presentation, and the status of distant metastasis ( all P ＜ 0. 05 ) , while gender, incidentally found at surgery, the size of primary tumor, the status of neck lymph node metastasis, recurrence after a primary resection, and the extent of surgical resection did not significantly effect the prognosis. Multivariate analysis showed the age more than 35 years at presentation was an independent risk factor indicating worse prognosis (P = 0. 045 ). Conclusioas The prognosis of patients with papillary thyroid microcarcinoma is satisfactory, but that is poor for those patients 35 years old and up at presentation and with distant metastasis.

Objective To investigate the prognostic factors of differentiated thyroid carcinoma (DTC) in patients younger than 45 years. Methods Clinical data of all patients less than 45 years old at presentation with DTC in our hospital from Jan 1985 to Dec 1997 were analyzed retrospectively. Single variable analysis was performed by life-table method. Multivariate analysis was performed by Cox proportional hazard model. Results Two hundred and seventy two cases were analyzed. The overall 10-year survival rate was 93. 0%. The main prognostic factors influencing survival were age at presentation, the status of lymph node metastasis and distant metastasis; distant metastasis was the risk factor independently influencing survival by multivariate analysis. Conclusions Distant metastasis is the factor influencing survival significantly. The prognosis of these patients without distant metastasis is good. Total or near-total thyroidectomy and postoperative 131I therapy may be essential for a better prognosis in patients with distant metastasis.

Objective:To investigate the predictive value of estimated renal perfusion pressure (eRPP) for acute kidney injury (AKI) in severe multiple trauma patients.Methods:Severe multiple trauma patients were collected based on the inclusion criteria and exclusion criteria from the Trauma Center, the Third Xiangya Hospital, Central South University. Subsequently, patients were divided into the AKI group and non-AKI group according to the occurrence of AKI during 72 h admission to hospital. Further clinical information, ISS score, SOFA score, APACHE Ⅱ score, mean arterial pressure (MAP), central venous pressure (CVP) and intra-abdominal pressure (IAP) were collected, and eRPP were calculated. Additionally, the differences of parameters in the AKI group and non-AKI group were analyzed and logistic regression analysis was performed to identify the independent predicted risk factors for AKI. Finally, ROC curve was conducted to identify specificity, sensibility and best cut-off point.Results:A total of 173 severe multiple trauma patients were finally analyzed. Compared with the non-AKI group, the serum albumin [(32.21±5.20)g/L vs. (34.83±4.20)g/L, P =0.001] and 24 h urine output [(711.90±241.38)mL vs. (1 101.21±509.86)mL, P =0.001] were significantly lower and serum lactate [(2.80±0.96)mmol/L vs. (1.89±0.63)mmol/L, P<0.001], ISS score [(29.05±5.91) vs. (22.17±4.02), P <0.001], APACHEⅡ score [(38.84±21.47) vs. (31.45±18.24), P <0.001] and SOFA score [(5.26±2.08) vs. (3.14±1.34), P <0.001], in-hospital mortality (9.52% vs. 2.29%, P=0.038), and ICU stay [(8.43±6.46)d vs. (6.42±3.78) d, P =0.01) were significantly higher in the AKI group. Moreover, 6, 12 and 24 h of CVP and eRPP after admission were associated with the incidence of AKI. Logistic regression analysis showed that 24 h urine output, CVP and eRPP were the independent predictive factors (P <0.05) and 24 h of eRPP after admission applied a better predictive value of the incidence in AKI. Conclusions:24 h of eRPP might be the most suitable independent predictive factor for AKI in severe multiple trauma patients.

Objectives To investigate the expression and clinical significance of BATF2 in the oral tongue squamous cell carcinoma(OTSCC).Methods Expression of BATF2 mRNA and protein in 16 paired OTSCC tissues and adjacent non-tumor mucosa were examined using quantitative PCR,western blotting analysis and immunohistochemistry assays,and the relation between BATF2 expression and clinical pathologic factor and prognosis was analyzed.Results In 16 paired tissues,expression of BATF2 mRNA in 13 OTSCC tissues and expression of BATF2 protein in 14 OTSCC tissues were significantly lower than that in adjacent non-tumor mucosa.In 202 paraffin-embedded OTSCC samples,BATF2 was not expressed in 20 cases(9.9％),low expressed in 104 cases(51.5％) and highly expressed in 78(38.6％).BATF2 expression level was significantly correlated with histological differentiation(P=0.002).Patients with low BATF2 expression had significantly poorer overall survival and disease-free survival than those with high BATF2 expression(P＜0.001).Conclusions BATF2 was low expressed in OTSCC and related to tumor differentiation and prognosis and may serve as a prognostic biomarker and potential therapeutic target for this disease.

Objective:To investigate the correlation between the clinical features and endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) in patients with cirrhosis.Methods:A total of 148 patients with cirrhosis and portal hypertension who underwent EUS-PPG measurement at the Third Xiangya Hospital of Central South University from March 15, 2022 to June 20, 2023 were selected. The clinical data of patients collected before EUS-PPG measurement were analyzed. Variations in the EUS-PPG across different clinical data subgroups were analyzed. Multivariate linear regression analysis was used to explore the independent factors influencing EUS-PPG.Results:The EUS-PPG was significantly elevated in patients exhibiting red signs (16.62±5.33 mmHg VS 13.44±5.34 mmHg, t=3.616, P<0.001), gastroesophageal varices (15.78±5.30 mmHg VS 9.70±4.77 mmHg, t=4.247, P<0.001), hepatic encephalopathy (20.83±7.52 mmHg VS 14.92±5.35 mmHg, t=2.606, P=0.010), thrombocytopenia (15.66±5.39 mmHg VS 13.29±5.83 mmHg, t=2.136, P=0.034), hypoproteinemia (16.13±5.86 mmHg VS 14.12±5.03 mmHg, t=2.230, P=0.027), and an increased international normalized ratio (16.25±6.00 mmHg VS 14.40±5.11 mmHg, t=2.022, P=0.045). Conversely, the EUS-PPG was significantly reduced in patients with a history of splenectomy and devascularization (13.17±5.88 mmHg VS 15.73±5.34 mmHg, t=-2.379, P=0.019). The EUS-PPG in patients with varying degrees of ascites (no VS slight VS moderate or severe: 13.40±5.48 mmHg VS 15.90±5.49 mmHg VS 16.69±5.17 mmHg, F=5.188, P=0.007) and different Child-Pugh classifications (A VS B VS C: 14.07±5.05 mmHg VS 15.69±5.74 mmHg VS 17.64±5.99 mmHg, F=3.066, P=0.049) increased gradually. Multivariable linear regression analysis showed that red signs ( β=2.44, t=2.732, P=0.007), gastroesophageal varices ( β=4.45, t=2.990, P=0.003), ascites ( β=1.75, t=2.368, P=0.019), and hepatic encephalopathy ( β=5.82, t=2.644, P=0.009) were independent factors for the elevated EUS-PPG. Conclusion:There is a significant correlation between EUS-PPG and the clinical features related to the severity of cirrhotic portal hypertension, which indicates the feasibility of EUS-PPG in evaluating cirrhotic portal hypertension.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

OBJECTIVE: To evaluate the treatment and prognosis of sinonasal mucosal melanoma (SMM). METHOD: Clinicopathological data of SMM patients from January 1976 to December 2005 were analyzed retrospectively. Survival analysis was performed and Kaplan-Meier analysis was used to compare the effect of clinicopathological factors on survival using SPSS 18.0 software. A Cox model was applied for multivariate analysis. RESULT: The 3-year and 5-year overall survival (OS) rates of 68 cases of SMM were 36.1% and 29.4%, respectively. The 3-year and 5-year OS of patients who underwent surgery or biotherapy were significantly higher than that of patients who underwent other therapeutic regimens without surgery or without biotherapy, respectively. Multivariate analysis showed the patients with distant metastasis at first present or residual/recurrence had a worse prognosis than that without distant metastasis or residual/recurrence, respectively. Surgery and biotherapy were effective treatments for SMM. CONCLUSION SMM has a poor prognosis, especially in the patients with distant metastasis or residual/recurrence. Surgery or biotherapy may improve the prognosis of patients with SMM.
