OBJECTIVETo study whether the caries status of the primary dentition correlated with status of the permanent in the same cohort over an eight-year period. To determine whether the caries status of the primary dentition can be used to predict caries in the permanent dentition.

METHODSA total of 362 children, 3 - 4 years old in the baseline study in 1992 were re-examined in 2000 based on WHO criteria and methods.

RESULTSStatistically significant associations were observed between the caries prevalence in primary and permanent teeth (P < 0.01) and between DMFT(s) and dmft(s) (P < 0.01). Children who had caries in the primary teeth were nearly three times more likely to have caries in the permanent teeth (RR = 2.6,95% CI = 1.4 - 4.7, P < 0.001). The highest sensitivity (93.9%) for prediction caries in the permanent dentition was found in caries presence on any of the eight primary molars, for which the relative ratio was 3.3 (95% CI = 1.8 - 6.1, P < 0.001) and the positive prediction value was 85.4%.

CONCLUSIONThe study determinate clearly that caries status in the primary teeth can be used as a risk indicator for predicting caries in the permanent dentition.

OBJECTIVETo compare the tubulogenesis capability of malignant glioma-derived microvessel endothelial cells (GDMEC) from human brain with that of ECV304 cells in a three dimentional model and to explore the significance of GDMEC in the study on angiogenesis.

METHODSThe GDMEC were isolated from malignant gliomas of human brain and purified by selective binding to the monoclonal antibody against CD105 bound to the magnetic MACS MicroBeads. GDMEC and endothelial-like cell line ECV304 were compared with their capabilities of formatting tubule-like structure (TLS) in the three dimentional collagen matrix, with or without inducement by various concentration of vascular endothelial growth factor (VEGF).

RESULTSThe obtained GDMEC had a high purification (98%) and could be successfully cultured in vitro. GDMECs formed more TLS than ECV304 cells of the same number and at the same time points. VEGF could induce rapid formation of TLS in a dose-dependent manner, however, ECV304 cells were less response to VEGF stimulation.

CONCLUSIONSGDMEC could maintain their endothelial characteristics and potential capability of angiogenesis. They were more response to VEGF than ECV304, therefore, more suitable for in vitro studies on tumor angiogenesis.

Recently, compound Ejiao slurry (FFEJJ) had been applied to treat cancer patients in clinic, with obvious curative effect. In this study, data and literatures were collected from the TCM chemical component database to establish the chemical component database of FFEJJ. Afterwards, MetaDrug software was used to predict the targets of FFEJJ and obtain the compound-target network. Next, the compound-target network was compared and analyzed to obtain the "compound-target-tumor target" heterogeneous network. Besides, further analysis was made on gene functions and metabolic pathway. The results indicated that FFEJJ could directly resist tumors by regulating cancer cell differentiation, growth, proliferation and apoptosis, and show an adjuvant therapeutic effect by enriching the blood and increasing the immunity.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Background: Endostatin, a biologically active fragment of collagen XVIII, has been observed in patients with ischemic heart disease. The aim of the present study was to investigate whether endostatin overexpression could attenuate cardiac hypertrophy by inhibiting the cyclic adenosine monophosphate-protein kinase A (cAMP-PKA) signaling pathway. Methods: This study was examined in vivo in rats and in vitro in primary neonatal rat cardiomyocytes treated with angiotensin (Ang) II to model cardiac hypertrophy. Twenty-four male Sprague-Dawley rats were randomized into adenovirus (Ad)-green fluorescent protein, Ang II, Ad-endostatin, and Ang II + Ad-endostatin groups (n = 6 in each group). Four weeks later, all the rats were weighed and sacrificed after transthoracic echocardiography. Cardiac function was evaluated by transthoracic echocardiography, cardiomyocyte size was evaluated by hematoxylin-eosin staining. Levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were evaluated by quantitative reverse-transcription polymerase chain reaction or Western blotting, PKA level was evaluated by Western blotting, and cAMP level was evaluated by enzyme-linked immunosorbent assay. Statistical significance among multiple groups was evaluated by one-way analysis of variance. Results: Endostatin overexpression reduced the increases in left ventricle (LV) mass (P = 0.0063), LV mass/body weight (BW) (P = 0.0013), interventricular septal thickness (IVS) in diastole (P = 0.0013), IVS in systole (P = 0.0056), left ventricular posterior wall thickness (LVPW) in diastole (P = 0.0291), LVPW in systole (P = 0.0080), heart weight (HW) (P = 0.0138), HW/BW (P = 0.0001), and HW/tibial length (P = 0.0372) in Ang II-treated rats. In addition, endostatin overexpression reduced cardiomyocyte cross-sectional area expansion, and reduced the levels of ANP and BNP in Ang II-treated rats (P = 0.0251 and 0.0477 for messenger RNA [mRNA]), and primary neonatal rat cardiomyocytes (P = 0.0188 and P = 0.0024 for mRNA; P = 0.0023 and 0.0013 for protein, respectively). Additionally, endostatin overexpression reduced the increase of cAMP (P = 0.0054) and PKA (P = 0.0328) levels in cardiomyocytes treated with Ang II. Treatment with cAMP reversed the effects of endostatin overexpression on ANP (P = 0.0263) and BNP (P = 0.0322) levels in cardiomyocytes induced by Ang II. Conclusion Endostatin overexpression could alleviate cardiac hypertrophy by inhibiting the cAMP-PKA signaling pathway.

The implementation of the New Plan is a complex work involving multiple parties and is affected by many factors. It requires multiple teams to perform their duties and promote together. The teacher training base and expert team must understand the spirit of reform and achieve the stable implementation of the New Plan ；at the same time ，the communication between the project working group and the teaching base and experts should be strengthened ，and finally realize the original intention of the reform of cultivating more high-quality clinical pharmacy teachers.

OBJECTIVETo investigate the effects of Salvia miltiorrhiza and Ligustrazine Injection (SML) on proliferation and apoptosis of human hepatic stellate cell LX-2 and the expression of N-myc downstreamregulated gene 2 (NDRG2, a tumor suppressor gene).

METHODSHSCs from the LX-2 cell line were cultured in vitro. The proliferative state of different initial LX-2 cell numbers was measured using a 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay. LX-2 cells were plated in 96-well plates at an approximate density of 2.50×10cells/mL and cultured for 24 h followed by the application of different concentrations of SML (1, 2, 4 and 8 μL/mL). Cell proliferation was measured using the MTT assay at 24 and 48 h. Apoptosis was detected by flow cytometry at 24 h. LX-2 cells were treated with different concentrations of SML and extracted with protein lysis buffer. The levels of NDRG2 and β-catenin were measured by Western blot.

RESULTSWith the exception of the 1 and 2 μL/mL concentrations, 4 and 8 μL/mL SML inhibited cell proliferation in a concentration-dependent manner at 24 and 48 h (P<0.05). With the exception of the 1 and 2 μL/mL concentrations, the NDRG2 expression level was greatly increased in a concentration-dependent manner. However, the level of β-catenin was unaffected.

CONCLUSIONSML inhibit LX-2 cell proliferation in a concentration-dependent manner, and the mechanism may be associated with NDRG2 over-expression.

OBJECTIVE To interpret Teacher Training Syllabus for Clinical Pharmacist Training Program （2023 edition） （hereinafter referred as to the “new syllabus”）， and to provide reference and guidance for promoting the implementation of the new syllabus and realizing the quality-improving goal of the reform of the clinical pharmacist teacher training program initiated by China Hospital Association. METHODS From the perspective of the management and based on the position of the designer， the new syllabus was interpreted from four aspects： the background of its compilation and release， the process of its compilation and its characteristics， the key improvements of the program and the points for attention about its subsequent implementation. RESULTS & CONCLUSIONS The development and release of the new syllabus provide a “construction blueprint” for the reform of the clinical pharmacist teacher training program of the China Hospital Association. The whole process of compiling the new syllabus is characterized by four basic features： theory-led， goal-oriented， research-based， and synergistic. Compared with the previous syllabus， in addition to the adjustment of the text structure，the new syllabus presents more complete and clearer competence requirements for clinical teaching competence in terms of training objectives； in terms of training content， it further structures the group of task items， pays attention to the 育。E-mail：zhenjiancun@163.com sequential planning and time arrangement of items， and puts forward both quantitative and qualitative refinement requirements for each specific training task；in terms of training methods， it emphasizes the interaction of lecturing， demonstrating and guiding， and the progression of observation， operation and reflection， with the intention of guiding teacher trainees to “learn how to teach by teaching”. In the subsequent implementation of the new syllabus， it is necessary for the teacher training bases to attach great importance to the guarantee of training conditions and process quality management， and to organize the teacher training team to do a good job in the two training programs of “clinical pharmacist training” and “clinical pharmacist teacher training”. Based on further improving the connection between the two training programs， the teacher training team should continue to explore the scientific model of clinical pharmacist teacher training oriented by clinical teaching competence.
