Objective To investigate the therapeutic effect of low-carbohydrate diet and online lifestyle intervention on patients with lean nonalcoholic fatty liver disease(NAFLD).Methods This study was conducted among 53 patients with lean NAFLD who attended Department of Infectious Diseases in Peking University Shenzhen Hospital and Shenzhen Qianhai Shekou Free Trade Zone Hospital from December 2019 to March 2021,and the patients were given low-carbohydrate diet for calorie restriction[total calorie intake was calculated based on basal metabolic rate(BMR)and physical activity level(PAL)and was restricted within(BMR×95%×PAL-1 000)kcal to(BMR×95%×PAL-500)kcal,and carbohydrate ratio fluctuated between 10%and 55%]and lifestyle interventions for 8 weeks.An online software was used for supervision and follow-up,and the patients were observed in terms of treatment outcome and safety.The patients were compared in terms of controlled attenuation parameter(CAP),liver stiffness measurement(LSM),Anthropometric parameters,blood biochemistry,urinary protein,and urine ketone body before and after intervention.The patients were followed up after 1 year to measure body weight and body mass index(BMI).The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the paired-sample Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous;the chi-square test was used for comparison of categorical data between groups.Results After 8 weeks of intervention,CAP decreased from 304.47±31.91 db/m to 242.43±26.74 db/m,LSM decreased from 7.43±2.41 kPa to 6.36±1.79 kPa,and body weight decreased from 64.29±7.37 kg to 60.24±7.08 kg(t=11.25,3.72,and 14.07,all P<0.001).Of all patients,25(47.2%)had disappearance of fatty liver,and abnormal LSM in 12 patients(63.2%)returned to normal;52 patients(98.1%)had a mean reduction of 4.05±2.32 kg in body weight.The degree of reduction in CAP increased with the degree of reduction in body weight.After intervention,there were significant reductions in BMI,waist circumference,hip circumference,alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transpeptidase(GGT),uric acid,fasting blood glucose,triglyceride(TG),total cholesterol(TC),and low-density lipoprotein(LDL)and a significant increase in high-density lipoprotein(t=12.85,13.77,10.28,7.64,6.21,8.35,6.83,6.31,7.4,4.97,5.95,and-2.21,all P<0.05).The patients with abnormal ALT,AST,GGT,uric acid,fasting blood glucose,TG,TC,and LDL at baseline which returned to normal after intervention accounted for 75%,100%,81.8%,57.1%,100%,66.7%,73.5%,and 85.3%,respectively.There were no significant changes in blood urea nitrogen,serum creatinine,urine protein,and urine ketone body(all P>0.05).There was no rebound in body weight and BMI after 1 year of follow-up(P>0.05).There were no gastrointestinal reactions during intervention or follow-up.Conclusion Low-carbohydrate diet and lifestyle intervention can improve liver fat content,liver function,and blood lipid parameters in patients with lean NAFLD,with good safety.

Objective:To investigate the effect of different spray-coagulation time of argon plasma coagulation (APC) injury on the Glisson system primary branche(G1) in the hepatic portal of pigs.Methods:Fifty clean healthy domestic pigs (27 females and 23 males, aged 7 to 14 months) were selected, with the body weighted (100.0±9.5) kg. They were randomly divided into five groups (A, B, C, D, and E), with 10 pigs in each group. G1 models were made and sprayed by APC for 1, 2, 3, 4, and 5 seconds. The damage, maximum damage area, maximum damage depth, and damage of the three branches of the Glisson system (the first branches of the portal vein, intrahepatic bile duct, and hepatic artery) were compared among the groups. The pigs were divided into two groups based on whether the three branches were damaged or not: the three-branch damage group ( n=23) and the control group ( n=27). The maximum damage area and maximum damage depth were compared between the two groups. Results:After the APC spraying, circular or elliptical damage appeared on the surface of the G1, with changes such as yellow-brown color, brown color, charred appearance, and defects. Under the microscope, G1 capsule was found to be deficient, the fibrous tissue beneath the capsule was ruptured, and the structures of small blood vessels and small bile ducts were incomplete. " Burn marks" and damage to the three branches of the Glisson system in G1 were also observed, and the damage was more severe at the center of the spray-coagulation. As the spray-coagulation time increased, the maximum damage area of the G1 model also increased, and the two were positively correlated ( r=0.90, P<0.001). The maximum damage depth was also positively correlated with spray-coagulation time ( r=0.97, P<0.001). The numbers of pigs with damage to the three branches of the Glisson system in Groups A-E were 0, 2, 5, 6, and 10, respectively, and the number of pigs with damage increased with the spray-coagulation time. In the three-branch damage group, the spray-coagulation time, maximum damage area, and maximum damage depth were all higher than those in the control group (without three-branch damage), and the differences were statistically significant (all P<0.05). Conclusion:The degree of damage to G1 caused by APC is positively correlated with the spray-coagulation time, and damage to the three branches of the Glisson system in G1 is related to the maximum damage area, maximum damage depth, and APC spray-coagulation time.

Objective:To explore the role of transgelin(TAGLN) in the occurrence and development of papillary thyroid carcinoma (PTC) and its possible signal pathway.Methods:One hundred cases of PTC tissues and corresponding paracancerous normal thyroid tissues were collected. Realtime quantitative PCR (RT-qPCR), Western blotting, and immunohistochemistry were used to analyze the expression of TAGLN in PTC tissues and corresponding paracancerous normal thyroid tissues. PTC cells were transfected with plasmid and shRNA lentivirus vector respectively to up-regulate or down-regulate the expression of TAGLN in order to detect the effects of them on the proliferation, invasion, and migration by cell proliferation assay(cell counting kit-8, CCK-8)and cell invasion and migration assays (Transwell). The effects of TAGLN on mitogen-activated protein kinase (MAPK)/extracellular-signal regulating kinase (ERK) signal pathway was detected with Western blotting.Results:RT-qPCR showed that there was no difference in the expression of TAGLN mRNA between PTC and corresponding paracancerous normal thyroid tissues ( P>0.05); Western blotting demonstrated that the expression of TAGLN protein in PTC tissues was significantly lower than that in corresponding paracancerous normal thyroid tissues ( P<0.01). Immunohistochemical results revealed that the expression of TAGLN in PTC tissues was significantly lower than that in corresponding paracancerous normal thyroid tissues. Overexpression of TAGLN inhibited the proliferation, invasion, and migration of PTC cells ( P<0.01), but knockdown of TAGLN promoted the proliferation, invasion, and migration of PTC cells ( P<0.01). Overexpression of TAGLN decreased the expression of phosphorylated ERK ( P<0.05), whereas silencing TAGLN increased phosphorylated ERK level in PTC cells( P<0.01). Conclusion:The expression of TAGLN in PTC is significantly decreased. It is related to the occurrence and development of PTC, and its mechanism may be related to MAPK/ERK signal pathway.

Unhealthy dietary habits and a sedentary lifestyle have led to a significant increase in the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in children, adolescents, and adults. In recent years, the biological-psychological-social medical pattern has attracted more and more attention, and internal psychosocial factors have become an important influencing factor for disease progression, treatment, and prognosis. Studies have shown that patients with NAFLD may experience psychosocial disorders, and this article summarizes the common psychosocial problems of these patients.

Objective: To investigate the effects of artesunate combined with bortezomib on the proliferation, apoptosis and autophagy of human acute myeloid leukemia cell lines MV4-11, and its mechanisms. Methods: MTT method was used to determine the anti-proliferation effect of different concentrations of artesunate, bortezomib and their combination on MV4-11 cells. The cell apoptosis were analyzed by flow cytometry. The expression of cleaved-Caspase-3, Bcl-2 family protein (Bcl-2, Mcl-1, Bim, Bax) and autophagy-related protein LC3B were assayed by Western blot. Results: Artesunate displayed a proliferation inhibition effect on MV4-11 with dose- and time-dependent manner, the IC₅₀ of artesunate on MV4-11 after 48 hours was 1.44 μg/ml. Bortezomib displayed a proliferation inhibition effect on MV4-11 with dose-dependent manner, the IC₅₀ of bortezomib on MV4-11 after 48 hours was 8.97 nmol/L. The combination of artesunate (0.75, 1.0 μg/ml) and Bortezomib (6, 8 nmol/L) showed higher inhibition on MV4-11 than artesunate or bortezomib alone in the same concentration gradient after 48 hours (P<0.05) . The cooperation index of the two drugs were all less than 1. The 48 h apoptotic rate of artesunate (1.5 μg/ml) on MV4-11 was (15.27±2.18) %, (19.85±3.23) % of bortezomib (8 nmol/L) , (81.67±5.96) % of combination of the two drugs, significantly higher than the single group (P<0.05) . When combination of the two drugs on MV4-11 after 24 hours, the levels of pro-apoptotic protein Bim and the cleaved activation of Caspase-3 and autophagy-related protein LC3B were up-regulated and the anti-apoptotic protein Bcl-2 expressions was down-regulated. Conclusion Combination of artesunate with bortezomib shows a significant synergistic effects on proliferation, apoptosis and autophagy of MV4-11 cell lines, which may be associated with Bcl-2 family proteins expression.
