To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

OBJECTIVE: To study the expression of multiple negative costimulatory molecules on peripheral blood T cells in patients with acute myeloid leukemia (AML) and its affection on prognosis. METHODS: The peripheral blood samples from patients with newly diagnosed AML, complete remission (CR), and no-remission (NR) were collected, the expression levels PD-1、VISTA and TIM-3 in CD4 and CD8 T cells were detected by flow cytometry , and the clinical data of patients were analyzed. RESULTS: The expression levels of PD-1、VISTA and TIM-3 of CD4 and CD8 T cells in the newly diagnosed AML patients were significantly higher than those in control group (P＜0.05). The expression levels of PD-1、TIM-3 and VISTA of CD4 and CD8 T cells in the CR group were significantly lower than those in newly diagnosed and the NR group (P＜0.05). The TIM-3 expression level positively correlated with VISTA expression level of CD4 and CD8 T cells in newly diagnosed AML patients (r=0.85 and 0.73). The VISTA and PD-1 expression level of CD4 T cells in newly diagnosed AML, NR after first induction chemotherapy and high risk patients significantly increased (P＜0.05), the TIM-3 expression level of CD8 T cells in high risk group significantly increased (P＜0.05), and the VISTA expression level of CD8 T cells in CBFβ-MYH11 mutation-positive group significantly decreased (P＜0.05). CONCLUSION The expression of PD-1、TIM-3 and VISTA in AML peripheral blood T cells may be involved in the immune escape of AML and can be the targets of treatment for acute myeloid leukemia patients.

With the rapid development of immunology, molecular biology, and associated technologies such as next-generation sequencing, cellular immunotherapy has recently become the fourth major cancer treatment. Immunotherapies based on T cells, natural killer cells, and dendritic cells play key roles in cancer immunotherapy. However, their application in clinical practice raises several ethical issues. Thus, studies should focus on proper adherence to basic ethical principles that can effectively guide and solve related clinical problems in the course of treatment, improve treatment effects, and protect the rights and interests of patients. In this review, we discuss cellular immunotherapy-related ethical issues and highlight the ethical practices and current status of cellular immunotherapy in China. These considerations may supplement existing ethical standards in cancer immunotherapy.

OBJECTIVE Metastasis-associated in colon cancer-1 (MACC1) is an oncogene that has been newly identified. It promotes tumor proliferation and invasion via the MET pathway. Our study investigated the effects of Saikosaponin-b(SS-b) on the proliferation and apoptosis of HepG2 cells and its regulation on MACC1/c-Met/Akt signaling pathway. METHODS HepG2 cells were treated with SS-b (10-800 g·L-1) for 48 h in vitro. The CCK-8 assay was used to assess cell proliferation, and cell apoptosis was determined by Hoechst33258 staining, AnnexinⅤ/PI staining and caspase 3 assay. RT-PCR was used to examine the expression of MACC1, c- MET and hepatocyte growth factor (HGF) mRNA. MACC1 protein was detected by Western blot and immunohistochemistry. The protein expressions of p-c-MET, c-MET, p-AKT, AKT, p-BAD, BAD were measured by Western blot. RESULTS SS-b inhibited the growth of HepG2 cells in dose-dependent way and induced cell apoptosis significantly. HepG2 cells showed karyopyknosis, fragmentation and fluorescence highlight in SS-b treatment group. FCM results showed that apoptosis rate of HepG2 cells increased with SS- b concentration. The immunofluores?cence results showed that the MACC1 expression decreased significantly in HepG2 cells treated with SS-b. The expression levels of MACC1, c-MET and HGF mRNA in HepG2 cells were significantly inhibited by SS-b. SS-b also significantly decreased the protein expressions of MACC1, p-c-MET and p-AKT while increased the expression of p-BAD and caspase 3 in HepG2 cells(P<0.05). CONCLUSION SS-b inhibited the proliferation and induced the apoptosis of HepG2 cells by targeting the MACC1/c-Met/Akt signaling pathway.

BACKGROUNDThe accuracy of three-dimensional (3D) reconstructions from cone-beam computed tomography (CBCT) has been particularly important in dentistry, which will affect the effectiveness of diagnosis, treatment plan, and outcome in clinical practice. The aims of this study were to assess the linear, volumetric, and geometric accuracy of 3D reconstructions from CBCT and to investigate the influence of voxel size and CBCT system on the reconstructions results.

METHODSFifty teeth from 18 orthodontic patients were assigned to three groups as NewTom VG 0.15 mm group (NewTom VG; voxel size: 0.15 mm; n = 17), NewTom VG 0.30 mm group (NewTom VG; voxel size: 0.30 mm; n = 16), and VATECH DCTPRO 0.30 mm group (VATECH DCTPRO; voxel size: 0.30 mm; n = 17). The 3D reconstruction models of the teeth were segmented from CBCT data manually using Mimics 18.0 (Materialise Dental, Leuven, Belgium), and the extracted teeth were scanned by 3Shape optical scanner (3Shape A/S, Denmark). Linear and volumetric deviations were separately assessed by comparing the length and volume of the 3D reconstruction model with physical measurement by paired t- test. Geometric deviations were assessed by the root mean square value of the imposed 3D reconstruction and optical models by one-sample t-test. To assess the influence of voxel size and CBCT system on 3D reconstruction, analysis of variance (ANOVA) was used (μ = 0.05).

RESULTSThe linear, volumetric, and geometric deviations were -0.03 ± 0.48 mm, -5.4 ± 2.8%, and 0.117 ± 0.018 mm for NewTom VG 0.15 mm group; -0.45 ± 0.42 mm, -4.5 ± 3.4%, and 0.116 ± 0.014 mm for NewTom VG 0.30 mm group; and -0.93 ± 0.40 mm, -4.8 ± 5.1%, and 0.194 ± 0.117 mm for VATECH DCTPRO 0.30 mm group, respectively. There were statistically significant differences between groups in terms of linear measurement (P < 0.001), but no significant difference in terms of volumetric measurement (P = 0.774). No statistically significant difference were found on geometric measurement between NewTom VG 0.15 mm and NewTom VG 0.30 mm groups (P = 0.999) while a significant difference was found between VATECH DCTPRO 0.30 mm and NewTom VG 0.30 mm groups (P = 0.006).

CONCLUSIONSThe 3D reconstruction from CBCT data can achieve a high linear, volumetric, and geometric accuracy. Increasing voxel resolution from 0.30 to 0.15 mm does not result in increased accuracy of 3D tooth reconstruction while different systems can affect the accuracy.

OBJECTIVEThrough reviewing the relevant literature from the past decades, to summarize the assessment and management of fractures of the clavicle, and provide an overview of the clinical results of a range of treatment options.

DATA SOURCESThe data analyzed in this review are mainly from articles included in PubMed and EMBASE, published from 1960 to 2015.

STUDY SELECTIONStudies involving assessment of fractures of the clavicle were reviewed. Further literatures were gathered regarding the conservative and surgical treatment of these fractures, including the methods of fixation and the surgical approaches used. Both conservative and surgical treatments were then compared and contrasted.

RESULTSThrough retrieving and reading the abstract, a total of 42 representative articles were selected, which covered all aspects of the conservative treatment and surgical treatment, and compared the advantages and disadvantages of different treatment options.

CONCLUSIONSAlthough the majority of recent data suggest that surgery may be more appropriate as it improves functional outcome and reduces the risk of complications, we recommend that the treatment should be individually assessed.
