Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Objective To explore the effects of 2,3,5,4'-tetrahydroxy stilbene-2-β-D-glycoside(TSG)on the over-expression and aggregation of α-synuclein in vitro.Methods TSG in different concentrations was incubated with α-synuclein transgenic COS-7 cells for 24 h.The cell viability was measured by MTT method.The expression of α-synuclein protein was determined by immunocytochemistry and Western blotting method.Results Incubation of TSG at the range of 12.5～200.0 μmol/L with α-synuclein transgenic COS-7 cells for 24 h did not influence cell viability,but a dose-dependently inhibition for the over-expression of α-synuclein protein could be observed in the tests of immunocytochemistry and Western blotting.Conclusion TSG can inhibit the over-expression of α-synuclein protein in COS-7 cells in vitro.

Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

Objective To investigate the inhibitory effect of carbon-coated iron nanoparticles carrying cisplatin on the growth of NCI-H446 lung cancer cells and expressions of Caspase 3 and Survivin mRNA.Methods NCI-H446 lung cancer cells were treated with iron-carbon nanoparticles and/or cisplatin.The cell viability was detected by MTT method,and the mRNA expressions of Caspase 3 and Survivin were measured with RT-PCR.Results Cisplatin could inhibit the growth of NCI-H446 lung cancer cells,and the inhibitory effect was stronger when it was combined with the iron-carbon nanoparticles.The cells had apoptosis.The mRNA expression of Caspase 3 of NCI-H446 lung cancer cells was remarkably enhanced after treatment with iron-carbon nanoparticles combined with cisplatin,while the mRNA expression of Survivin was notably weakened (P＜0.05).Conclusion Carbon-coated iron nanoparticles carrying cisplatin could significantly increase the chemotherapy sensitivity of cisplatin on NCI-H446 lung cancer cells and enhance the therapeutic efficacy of chemotherapy drugs.

Objective To explore the effects of under-expression of large tumor suppressor 1 (LATS1) on activation of Hippo signaling pathway and differentiation, proliferation, migration of bone marrow mesenchymal stem cells (mMSCs) of micein vitro.Methods mMSCs of C57BL/6 mice were divided into normal control (MSC) group, empty vector control (MSC-GFP) group, LATS1-over-expressing (MSC-LATS1) group, empty vector without LATS1 shRNA control (MSC-shControl) group and LATS1-under-expressing (MSC-shLATS1) group. Lentiviral vectors with activated,inactivated LATS1 (the key molecule of Hippo signaling pathway) modifications and empty vectors were constructed and were used to infect mMSCsin vitro. The transduction efficiencies mediated by the lentiviral vectors were evaluated by fluorescence microscopy and flow cytometry. The mRNA expression of LATS1 was quantified by quantitative real-time polymerase chain reaction (qRT-PCR), and the protein expressions of LATS1, YAP (p-YAP), 14-3-3 were quantified by Western Blot to evaluate the activation of Hippo signaling pathway. Osteogenic and adipogenic differentiation of mMSCs were evaluated through measurement of Runx2, OSX and C/EBPα, PPAR-γ mRNA by qRT-PCR, as well as Alizarin Red S and Oil red O staining. Proliferation of mMSCs was evaluated using methy thiazdyl tetrazolium (MTT) assay. The scratch test and Transwell chamber test were used to analyze the horizontal and vertical migration ability of mMSCs.Results The transduction efficiencies mediated by the lentiviral vectors were 94.74%-96.10%.
