OBJECTIVE: To investigate the expression and significance of B and T lymphocyte weakening factor (BTLA) in patients with chronic myelomonocytic leukemia (CMML). METHODS: Real-time PCR was used to detect the expression of BTLA and its ligand HVEM mRNA in 11 patients with chronic myelomonocytic leukemia and 11 normal donors. Flow cytometry was used to detect expression of BTLA and its HVEM on the cell surface of peripheral blood T lymphocytes and γδ T cells. RESULTS: The median values of BTLA and its ligand HVEM mRNA expression in peripheral blood of patients with CMML were 0.009% and 559.4%, respectively, which were significantly lower than those of normal controls (0.053% and 1031%)(P<0.001). The expression level of BTLA and HVEM on cell surface of peripheral lymphocytes was not significantly different from that in normal controls (P=0.3031 and 0.2576), however, the proportion of peripheral blood T lymphocytes in patients with CMML (median: 37.73%) was significantly lower than that in controls (median 69.23%)(P=0.0005). The expression of BTLA on the surface of γδ T cells in peripheral blood of patients with CMML (median: 23.26%) was significantly lower than that of the controls (median: 52.64%) (P<0.05), and there was no significant abnormality in HVEM expression (P=0.2791). CONCLUSION The expression of BTLA and its ligand HVEM, the proportion of T lymphocytes and the expression of BTLA on the surface of γδ T cells in patients with CMML are reduced. The effects of these abnormalities on T cell function and prognosis and efficacy of patients need to be further observed.

Atherosclerosis-related diseases have increasingly become health concerns with the increased living conditions and aging.Globally,about 200 million people have suffered from arteriosclerosis obliterans(ASO),which can even be life-threatening in some cases.The past seven decades have witnessed the rapid advances in the treatment of ASO,which has developed from surgery to endovascular interventions including plain balloon angioplasty,bare metal stent placement,drug-coated balloon,and drug-eluting stent.However,the roles of these new techniques for femoral-popliteal lesions,especially their real-world clinical outcomes and indications,remain unclear.This article reviews the latest evidences on the use of drug-eluting devices in treating femoral-popliteal arteriosclerosis obliterans.

Chemical investigation on the rice culture of Corynespora cassiicola J9, an endophyte inhabiting in Blumea balsamifera (L.) DC. resulted in isolation of eight compounds, including a new depsidone derivative, corynether C (1), and seven analogues, corynether B (2), corynetherlactone A (3), corynether A (4), diaryl ether (5), corynesidone C (6), corynesidone D (7), and corynesidone A (8). Their structures were deduced based on 1D and 2D NMR spectroscopy, and HR-ESI-MS data. All of the isolated compounds were evaluated for inhibitory activities against Lissorhoptrus oryzophilus Kuschel by the leaf spray assay. Unfortunately, none of them showed inhibitory effects.

Hepatitis B virus (HBV) infection is a leading cause of hepatocellular carcinoma (HCC) in China. The occurrence of HCC can significantly be reduced with effective long-term antiviral treatment. Since the widespread clinical use of nucleos(t)ide analogues, such as entecavir and tenofovir that has a strong potency and high genetic barrier to resistance; the detection rate of HBV DNA in serum of patients with chronic hepatitis B is no more than 85% ~ 95%, but HCC can still occur in a small number of patients. This article will review whether the timing and selection of NAs treatment differ to prevent and reduce the incidence of HCC.

Objective: To discuss the efficacy of computer aided design (CAD) and computer aided manufacturing (CAM) in the treatment of microgenia by osseous genioplasty. Methods: From July 2015 to January 2018, 17 cases (Male, n=5, Female, n=12), aged from 17 to 32 years, with the meanage of 24 years, were enrolled. All patients had microgenia, and underwent osseous genioplasty. Computed tomography (CT) was performed preoperatively and 7-10 days postoperatively for all cases. Based on preoperative CT data, CAD was applied to make individualized surgical plan, surgery simulation, todetermine the movement of mentum. CAM was used to prefabricate the individualized surgical templates and transfer the CAD into intraoperative guidance. The registration of CAD and postoperative CT were performed to evaluate the surgical accuracy. Results: All patients were satisfied with the surgical outcomes. The deformity of microgenia was significantly corrected. The Pg error was (0.24±0.08) mm, and the Me error was (0.15±0.17) mm. Conclusions The application of CAD increases the accuracy of surgical planning, and CAM provides areliable guidance with individualized template. Anoptimal surgical outcome can be achieved.

Excessive salt intake is an important risk factor of diseases such as hypertension, stroke, and stomach cancer. China is one of countries with high salt intake in the world. Recently, the intake of sodium from pre-packaged foods in China has been increasing, and the situation of salt control is rigorous. Based on the summary of the domestic and international experience of salt reduction, the "Guidelines for Salt Reduction in Chinese Food Industry" presents the basic principles, targets at different stages within various categories, technical routes, steps and measures, and social environment co-construction of salt reduction in Chinese food industry. This article focuses on the background, basis, process, key content and promotion of the guideline. The implementation of this guideline will contribute to the vigorous advancement of salt reduction action in Chinese food industry.

AIM:To investigate the effects of titanium dioxide(TiO2)nanotube arrays on the early adhesion behavior of Porphyromonas gingivalis(Pg),Tannerella forsythia(Tf)and Actinobacillus actinomycetemcomitans(Aa)be-fore and after loaded with minocycline hydrochloride(MN).METHODS: TiO2nanotube arrays were prepared by ano-dization and loaded with MN.Titanium slices were divided into 3 groups according to different treatment methods: pure polishing titanium(Ti)group,TiO2nanotube titanium(TiO2)group, and MN(120 μg)TiO2nanotube titanium(MN TiO2)group.The antibacterial properties of the titanium tablets were evaluated by the bacteriostasis test.RESULTS:The Ti had no antibacterial activity.The antibacterial activity of TiO 2to Aa,Pg and Tf was poor,with only about 20%of anti-bacterial rate after 4 h.After loaded with MN,its antibacterial activity was enhanced,and the antibacterial rate was up to 77%after 4 h.CONCLUSION: No antibacterial activity in the Ti group was observed.If TiO2nanotube arrays were formed on the surface and MN was loaded,the antibacterial activity on periodontal pathogens was stronger.
