This study aimed to investigate halofuginone's inhibitory effect and mechanism on the activity of hepatocellular carcinoma cells. HepG2 cells were used to detect the effects of halofuginone. After treatment, cell activity, cell migration, cell cycle, and cell apoptosis were detected by CCK-8, transwell, and flow cytometry, respectively. The expression levels of growth and metabolism-related factors such as citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and isocitrate deoxygenase (IDH) were detected by real-time quantitative PCR and Western blot. Compared with the control group, the activity of HepG2 cells was significantly inhibited by halofuginone (P < 0.01), the migration rate of HepG2 cells was decreased (P < 0.01), the apoptosis of HepG2 cells was induced (P < 0.01), and the cell cycle was arrested in S phase (P < 0.01). The expression levels of tricarboxylic acid key enzymes CS, IDH3, and OGDH were up-regulated, the expression level of isocitrate dehydrogenase isoenzymes IDH1 and IDH2 were down-regulation. In conclusion, halofuginone can inhibit the proliferation and migration of HepG2 cells and promote apoptosis in a dose-dependent manner, which may be due to the promotion of the aerobic metabolism of cells.

Objective To investigate the expression of lymphoid enhancer binding factor 1(LEF1)in B cell chronic lymphoproliferative disorders(B-CLPD)and estimate its value in the differential diagnosis of the subtype of B-CLPD.Methods A retrospective study was conducted on 58 patients diagnosed with B-CLPD by using bone marrow biopsy samples or lymphnode biopsy samples from Hematology Department of The Second People′s Hospital of Wuhu from September 2018 to June 2023,as well as 20 bone marrow biopsy samples which were diagnosis as non-hematologic malignancy in the control group.Immunohistochemical method was used to detect the expression of LEF1 in 78 samples,and statistical analysis was conducted.Results In all 78 cases,16 of 20 chronic lymphocytic leukemia(CLL)patients were LEF1 positive,the positive rate was 80%;mantle cell lymphoma 1/12;Follicular lymphoma 1/5;marginal zone cell lymphoma 0/11;Lymphoplasmacyticlymphom 0/8;hairy cell leukemia 0/2;in Control group no patient was LEF1 positive(P = 0.000).The expression of LEF1 is correlated with CD200 and CLL score(P<0.05).In the LEF1 negative group with 4 CLL patients,2 were detected with +12 chromosomal abnormality,the detective rate was higher than that of the LEF1 positive group(P>0.05).Conclusion LEF1 was a sensitive and specific diagnosis marker in CLL and B-CLPD subtype.

As the country with the largest number of new cancer cases and deaths,China faces a serious situation with a large cancer population base,low relative survival rate,and low adherence to cancer screening.Neighboring Japan,which has the longest life expectancy in the world,has a much higher relative survival rate than China,despite having a similarly high cancer rate,due to its well-established system of cancer prevention and control.Being an Asian country,the major prevalent cancers in China and Japan are similar in spectrum and can be referred to more.This article introduces the construction of Japan's cancer life-cycle prevention and control system of"cancer prevention","cancer care",and"coexistence with cancer"starting from the three major goals of Japan's cancer prevention and control program,and focuses on the improvement of cancer screening in Japan and the improvement of cancer survival in China.It also highlights the means and methods used to increase the cancer screening rate in Japan,with a view to providing suggestions for cancer prevention and control in China.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Invasive fungal infections threaten the lives and health of humans, especially immunodeficient patients or hospitalized patients with serious underlying diseases, and impose a heavy economic burden on society. The emergence of drug-resistant fungi, the formation of biofilms, and the limits and side effects of existing antifungal drugs increase the difficulty of clinical treatment, and there is an urgent need for the development of novel antifungal drugs. Therefore, based on previous kinase chemical library antifungal activity screening studies, this paper further investigates the activity of anaplastic lymphoma kinase (ALK) inhibitor 3-[5-chloro-2-({2-methoxy-4-[4-(4-methylpiperazin-1-yl)hexahydropyridin-1-yl]phenyl}amino)pyrimidin-4-yl]-1H-indole (HG-14-10-04, HG) against various fungi and elucidates its mechanism of action. The in vitro antifungal activity of HG was evaluated by micro liquid-dilution method, time-killing curve, mycelium formation and biofilm formation assays. The results showed that HG exhibited inhibitory and even fungicidal effects against sensitive and resistant Candida albicans, Candida krusei, Cryptococcus neoformans, Candida tropicalis, Candida glabrata and Candida parapsilosis (MICs = 8-16 μg·mL^-1); HG significantly inhibited the mycelium and biofilm formation, and destroyed the mature biofilm; and it exhibited synergistic antifungal effects with amphotericin B. The antifungal mechanism of HG was investigated by flow cytometry and transmission electron microscopy, etc. Sequencing analysis showed a total of 1 041 differentially expressed genes, of which 666 were up-regulated and 375 were down-regulated. According to the GO functional classification results, the up-regulated genes were mainly involved in ribosome production, oxidation-reduction and other functions, while the down-regulated genes were mainly involved in the synthesis of carbohydrate, glycoproteins, glycolipids and their metabolism, GPI anchor synthesis, and cytoskeleton and other functions. In addition, HG could significantly increase the level of reactive oxygen species (ROS), induce the fungal necrosis, block the cell cycle at the G0/G1 phase, and change the ultrastructure of the fungi, especially the structure of the fungal cell wall. Therefore, the enhanced inhibitory and fungicidal activity of HG may be related to the elevation of ROS, alteration of cellular ultrastructure (especially cell wall structure) and cell cycle arrest at the G0/G1 phase. Further optimization of its structure will provide a basis for the discovery of novel antifungal drugs or lead compounds.
