Objective To determine the effect of hypoxia conditions on the expression of autophagyrelated genes including P62,LC3 and Beclin-1 in the gastrocnemius muscles of rats with alimentary obesity and the possible mechanism of cellular autophagy induced by hypoxia exercises.Methods The model of rats with alimentary obesity was induced in Sprague-Dawley rats using high-fat diet.Then the obese rats were randomly divided into a control(C) group,a hypoxia-exercises-for-1-week(E1) group,a hypoxia-exercises-for-2-weeks (E2) group,a hypoxia-exercises-for-3-weeks (E3) group and a hypoxia-exercises-for-4-weeks(E4) group,each of 10.The rats were exposed to the environment where the simulated hypoxia was of about 13.6％ oxygen concentration(about the oxygen concentration at an actual altitude of 3,500 m),and underwent treadmill running with the speed at 20 m/min on a slope of 0 gradient every day,five days a week.After the last training,the rats were killed and sampled.The RT-PCR was used to detect the level of P62,LC3 and Beclin-1 mRNA and Western Blotting was conducted to examine the changes of protein P62 and LC3 before and after the intervention.Results Compared with group C,the expression of Beclin-1 mRNA in group E1,E2 and E3 increased significantly(P＜0.05),while the expression of protein Beclin-1 decreased significantly in group E2.The expression of protein Beclin-1 of group E2 and E3 was significantly lower than that of group E4,but there were no significant differences between group E2 and E3.Compared with group C,the relative expression of P62 mRNA in group E1 and E2 increased significantly(P＜0.05,P＜0.01),with that of group E2 significantly higher than group E1 (P＜0.05).Moreover,the relative expression of P62 mRNA in group E3 was significantly lower than that of E2(P＜0.01),and that of group E4 was significantly higher than group C,E1 and E3(P＜0.01).The relative expression of protein P62 in the obese rats in group E3 was significantly higher than that of group E2(P＜0.05).The relative expression of LC3 mRNA in group E2,E3 and E4 was significantly higher than that of group C(P＜0.01).Moreover,there were no significant differences in LC3-Ⅱ/LC3-Ⅰ protein among the five groups.Conclusion Hypoxia exercise can significantly enhance the relative expression of autophagy genes,and promote,to some extent,the autophagy.However,the transcription of autophagy genes does not happen synchronically with the synthesis of autophagy proteins.Moreover,an increase in autophagy in the skeletal muscle can be seen in the first two weeks of hypoxia exercises,followed by a gradual decrease with time prolonged,which may be the result of the gradual adaptation to hypoxia stimulation of the body.

Objective To investigate the correlation between interferon γ-inducible protein-10 and expression of peroxisome proliferator-activated receptor (PPAR) and fatty acid-binding protein-4 (FABP-4) in pregnant women with preeclampsia. Methods 62 PE pregnant women who were treated in our hospital from January 2016 to January 2017 were enrolled in this study. They were divided into mild PE group (34 cases) and severe PE group (28 cases) according to their severity of disease. In addition, 30 healthy pregnant women in our hospital were selected as the control group. The levels of IP-10 in the three groups were measured by enzyme-linked immunosorbent assay (ELISA), and the levels of PPAR and FABP-4 and the correlation between them were analyzed using western blot assay. Results The levels of IP-10 in mild and severe PE pregnant women were significantly higher than those in the control group, and the mild group was lower than the severe group(P＜0. 05). Compared with the control group, the level of PPAR in mild and severe PE pregnant women decreased significantly, and the severe group was lower than the mild group (P＜0. 05). Compared with the control group, FABP-4 levels in mild and severe PE groups were significantly elevated, and the mild groups was lower than the severe group(P＜0. 05). There was a negative correlation between the level of PPAR and IP-10 (r=-0. 529, P＜0. 05), and a positive correlation between FABP-4 and IP-10(r=0. 692, P＜0. 05). Conclusion There is a certain correlation between PPAR and FABP-4 and the level of IP-10 in pre-PE pregnant women. lt can be used to determine the condition of pre-PE in pregnant women.

This article summarizes the current research on the involvement of TIPE2 in the pathogenesis of different liver diseases and points out that TIPE2 may become a new target for the treatment of liver diseases.

Objective: To investigate the role and mechanism of action of Yiqi Huoxue Recipe (YQHXR) in regulating autophagy and reversing liver fibrosis in rats with carbon tetrachloride (CCl4)-induced liver fibrosis. Methods: Healthy male Wistar rats were intraperitoneally injected with a mixture of CCl4 (30%) and olive oil (70%) twice a week for 8 weeks to establish a rat model of liver fibrosis. The rats administered normal diet were used as control group. Furthermore, YQHXR or Fuzheng Huayu Recipe (FZHYR) was intragastrically administered to the rats. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using an automatic biochemical analyzer. Hematoxylin-eosin (HE) staining and Masson staining were performed to observe the degree of fibrosis in rat liver. The protein expression of α-smooth muscle actin (α-SMA) and type I collagen α1 chain (Col1A1) in liver tissue was measured by immunohistochemistry. Furthermore, the mRNA and protein expression of α-SMA, Col1A1, autophagy-related protein 7 (Atg7), microtubule-associated protein 1 light chain 3 (LC3), and ubiquitin-binding protein (SQSTM1/p62) were determined using qRT-PCR and Western blotting, respectively. Comparison between multiple groups was made by one-way analysis of variance, and comparison between any two groups was made using the LSD test. P < 0.05 was considered as statistically significant. Results: The YQHXR group and FZHYR group had significantly lower serum levels of ALT and AST than the model group (ALT: 66.8±10.42 U/L and 73.2±10.33 U/L vs 106.80±18.24 U/L, F = 31.672, P < 0.001; AST: 122.6±16.65 U/L and 125.4±16.92 U/L vs 278.4±66.14 U/L, F = 25.539, P < 0.001). The pathological grades of hepatic fibrosis were S5.64±0.22, S3.70±0.35, and S3.90±0.34 in the model group, YQHXR group, and FZHYR group, respectively (F = 362.188, P < 0.001). Compared with the control group, the YQHXR group and FZHYR group had significantly reduced mRNA and protein expression of α-SMA, Col1A1, Atg7, and LC3B and significantly increased expression of p62 (all P < 0.05), and the differences were greatest in the YQHXR group. Conclusion YQHXR and FZHYR can prevent or reverse liver fibrosis by regulating hepatocyte autophagy and inhibiting hepatic stellate cell activation and collagen deposition.

Objective:To analyze the clinical and pathological characteristics of chronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT) and not receiving antiviral therapy.Methods:This study retrospectively included CHB patients diagnosed by liver biopsy at the Third Hospital of Hebei Medical University from January 2008 to December 2022. According to the HBV DNA and HBeAg status of "immune tolerance period and immune control period", these patients were divided into three groups: chronic HBV carrier group, inactive HBsAg carrier group and indeterminate group including the patients that did not meet the inclusion criteria of the above two groups. Kruskal-Wallis H test was used for comparison of continuous data between multiple groups. Mann-Whitney U test was used for comparison of continuous data and ordered categorical data between two groups. Chi-square test or Fisher′s exact test was used for comparison of categorical data between two groups. Results:A total of 284 CHB patients with normal ALT were enrolled. There were 64, 88 and 132 cases in the chronic HBV carrier group, inactive HBsAg carrier group and indeterminate group, respectively. Histopathological analysis revealed that there were 182 (64.08%) cases with pathological inflammation grade (G) and/or fibrosis stage (S)≥2, 155 (54.58%) with S≥2 and 120 (42.25%) with G≥2. The proportion of patients with G and/or S≥2 in the indeterminate group [70.45% (93/132)] was higher than that in the chronic HBV carrier group [48.44% (31/64)] and inactive HBsAg carrier group [65.91% (58/88)] (both P<0.05). Patient′s age and the ratio of patients with S≥2 in the chronic HBV carrier group [33 years old, 39.06% (25/64)] were smaller than those in the inactive HBsAg carrier group [39 years old, 56.82% (50/88)] and the indeterminate group [39 years old, 60.61% (80/132)] (all P<0.05). Patients in the inactive HBsAg carrier group (19 U/L) had lower ALT levels than those in the chronic HBV carrier group (26 U/L) and the indeterminate group (23 U/L) (both P<0.05). The proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg was higher in patients with G and/or S≥2 than in patients with G and S<2 [73.08% (57/78) vs 32.08% (17/53), P<0.05], and the proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg increased gradually with age. The proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg was higher in patients with G and/or S≥2 than in patients with G and S<2 in the chronic HBV carrier status and indeterminate groups [93.33% (28/30) vs 43.33%(13/30), P<0.05; 59.46% (22/37) vs 12.50% (2/16); both P<0.05]. There was a statistically significant difference in the incidence of significant liver injury between patients≤ 30 years old and >30 years old [52.7% (39/74) vs 68.1% (143/210), P<0.05]. Conclusions:Significant liver injury occurred in 64.08% (182/284) of CHB patients with normal ALT not receiving antiviral therapy, which required the attention of clinicians. Among CHB patients with normal ALT, the expression site of HBcAg in hepatocytes was related to the occurrence of significant liver injury and could be expected to serve as an important indicator for predicting the patient′s status and the necessity of antiviral treatment. CHB patients with positive HBV DNA who were older than 30 years required antiviral treatment, and CHB patients≤30 years with normal ALT and significant hepatic tissue damage also required antiviral treatment.

Liver fibrosis occurs due to damages caused by liver diseases of various etiologies and activation of hepatic stellate cells, leading to the repairing and damaging cycle by secreting a large amount of extracellular matrix and formation of fibrosis tissues in the liver. Early reversal of this process could prevent further development and progression of the disease, which may reduce incidence of the end-stage liver disease and even liver cancer. This review summarized and discussed recent advancements and mechanisms of liver sinusoidal endothelial cells, Notch signaling pathway, YAP/TAZ signaling pathway, and autophagy in regulation of liver fibrosis and then enumerated the Traditional Chinese Medicine in reversal of liver fibrosis process and the underlying molecular mechanisms. It expects to provide novel approaches and research ideas for future control of liver fibrosis using Traditional Chinese Medicine.

Objective To summarize the clinical features of patients with Wilson's disease (WD). Methods A retrospective analysis was performed for the clinical data of 83 patients with WD who were admitted to The Third Hospital of Hebei Medical University from April 2013 to August 2021, including clinical manifestations, Imaging examinations, laboratory examinations, liver histopathological examinations, and ATP7B gene testing results. The patients were divided into groups based on different clinical types. A one-way analysis of variance was used for comparison between groups. Results The youngest age was 3 years for the 83 patients with WD, among whom 39 (46.99%) had an age of ≤18 years, with a mean age of 21.16±14.87 years for all 83 patients. Of all patients, 63.86% had liver-type WD, 31 patients (37.35%) had developed liver cirrhosis at the time of consultation, and 5 patients (6.2%) attended the hospital due to acute or acute-on-chronic liver failure. Of all patients, 62(74.69%) were positive for corneal K-F ring, and the positive rate of K-F ring was 66.04% in the patients with liver-type WD. Among the 83 patients, 79(95.18%) had a reduction in blood ceruloplasmin, and 73(87.95%) had an increase in 24-hour urine copper. The liver histopathological results of 25 patients showed varying degrees of inflammation, fibrosis, steatosis, and copper particle deposition in liver tissue. The ATP7B gene testing results of 25 patients showed that c.2333G > T/p.R778L of exon 8 was the most common mutation site. Conclusion Most patients with WD have the manifestation of liver diseases, and the examinations of corneal K-F ring, serum ceruloplasmin, and 24-h urine copper have their own limitations. Liver pathology and ATP7B gene testing can be performed when it is unable to make a confirmed diagnosis.
