Objective To estimate the clinical effect of cutting titanium inlay crown in the restoration of short cracked molar. Methods Sixty-four short coronal cracked teeth were randomly divided into group A and group B. Group A were treated by crown. Group B were treated by titanium inlay crown. The curative effect was evaluated every year and lasted 2 years. Results One year after the repair, there was no significant difference in the achievement ratio between two groups (93.8%vs 100%,χ2=2.064, P>0.05). Two years after the repair, the success rate was significantly higher in group B (96.9%) than that of group A (68.8%,χ2=8.892, P<0.01). The failed cases of group A were treated by cutting titanium inlay crown, showing good retention. Conclusion The retention of a short cracked molar can be improved by means of cutting titanium inlay crowns.

Morus alba L. (mulberry) is a well-known deciduous tree, belonging to the genus of Morus of Moraceae famlily. Its leaves, twigs, roots (bark) and fruits are widely used in the traditional Chinese medicine. The active constituents of mulberry contained flavonoids, alkaloids, steroids, coumarins, with the significant hypoglycemic, hypolipidemic, antihypertension, anti-oxidation, anti-inflammatory, anti-bacterial, anti-tumor and immunomodulatory activities. This review summarized the research progress of the major pharmacological activity, pharmacokinetics and drug-drug interaction based on CYPs and transporters of mulberry and its active constituents.

Objective To identify the targeted-regulating relationship between human MicroRNA335 (hsa-miR-335 )and CCL1 1,CCL26 and SOX4.Methods The potential fragments of hsa-miR-335 target genes CCL1 1,CCL26 and SOX4 were predicted by the bioinformatics analyzing tools online.The 3′untranslated regions(3′UTR)of the CCL1 1,CCL26 and SOX4 were connected to the eukaryotic expression vectors pMIR REPORT.The constructs of pMIR-REPORT-CCL1 13′UTR,pMIR-REPORT-CCL26 3′UTR,pMIR-REPORT-SOX4 3′UTR and positive control were co-transfected with Pre-miRTM miRNA335 Precursor or negative control into 293 T7/1 7 cell line by lipofectamine 2000,respectively.Both Firefly and Renilla luciferase activity were detected by dual luciferase reporter assay system.Results Compared with the negative control group,luciferase assay revealed that has-miR-335 could significantly diminish luciferase activity from SOX4 reporter vector (P <0.01 ),while the suppression of luciferase activity was not found in CCL1 1 or CCL26 reporter vector (P >0.05).Conclusion The results suggested that hsa-miR-335 targeted regu-lated SOX4,but not targeted CCL1 1 and CCL26.

Through the research and practice of computer basic course at medical colleges, the paper summarizes the experience of using modern technical means, to reform the traditional teaching ideas, teaching methods, teaching means and teaching management, to diversify teaching resources sharing. It also analyzes the shortcomings and makes recommendations to further strengthen the course development.

Objective To explore the effects of borderline personality disorder (BPD) tendency and impulsivity on suicide ideation in counseling patients.Methods A total of 120 counseling patients were evaluated by the Personality Diagnostic Questionnaire (PDQ-4+),Barratt Impulsiveness Scale (BIS-11).All participants were also interviewed with self-made structured clinical questionnaire for suicide ideation.Re sults ①Patients with suicide ideation had significantly higher score of BPD tendency ((6.02 ± 2.15) vs (3.91±2.31),t=5.164,P＜0.01),impulsivity ((72.05±8.58) vs (68.63±9.01),t=2.129,P=0.035) than patients without suicide ideation.There was still significant difference of BPD tendency between the two groups after controlling for gender(F=23.135,P＞0.01) but there was no significant difference of impulsivity (F=3.536,P＞0.05).②Logistic hierarchical regression analysis revealed that only BPD tendency (B=0.319;P=0.009;OR=1.375)had a significant role in the prediction of suicide ideation after controlling for gender and depressive diagnoses.Conclusion Compared with impulsivity,BPD tendency can better predict suicide ideation of counseling patients.

AIM To develop the quality control methods for Yixuning Tablet (Fructus Lycii,Radix Polygoni Multiflori Preparata,Radix Codonopsis,etc.) METHODS RP-HPLC was performed for the assay of 2,3,5,4′-tetrahydroxy-stilbene-2-O-?-D-glycoside.TLC was used to identify Fructus Lycii,Radix Polygoni Multiflori,and Radix Angelicae Sinensis. RESULTS The good linearity was within the range of 20-180 ?g?mL -1 ( r = 0.999 9 ).The average recovery was 99.0 % ( RSD was 2.8 T《B》 % ).TLC methods were special. CONCLUSION The method is convenient,accurate and sensitive.and suitable for the quality control of the preparation.

恶性肿瘤居中国各类疾病死因之首，发病率与病死率呈逐年上升趋势。近几年来靶向治疗已广泛应用于临床，显示 出良好的抗肿瘤效果，新靶点的探索和鉴定在靶向药物研发过程中起着重要作用。E3泛素连接酶斑点型锌指结构蛋白（speckletype POZ protein，SPOP）作为治疗选择的潜在靶点，能特异性识别底物，使底物发生泛素化降解，广泛参与机体内多种生理、病理 过程。研究发现SPOP基因突变或表达水平改变，通过调控AR/ERG、Akt-mTORC1、Hedgehog/Gli2等多种信号通路影响恶性肿 瘤的发生发展，并与前列腺癌、肾癌、结直肠癌等多种恶性肿瘤细胞增殖及远处转移密切相关。目前，SPOP影响恶性肿瘤发生发 展的相关研究为靶向治疗恶性肿瘤奠定了基础，综述SPOP在恶性肿瘤的最新进展对抗肿瘤研究具有重要的意义。

AIM: To evaluate the therapeutic efficacy and safety of heavy silicone oil (HSO), Densiron 68, was used as internal tamponade to treat complex vitreoretinopathy.METHODS: A retrospective study of 30 patients (30 eyes) who underwent vitrectomy and HSO tamponade for complex retinal detachment between January 2015 and January 2016.The best corrected visual acuity (BCVA), intraocular pressure (IOP), retinal reattachment and complications after surgery were observed.RESULTS: There were statistical significances in both the BCVA difference between pre-operation and HSO tamponade, and the BCVA difference between pre-operation and the removal of HSO for 3mo (z=-2.198, P=0.028;z=-2.682, P=0.007).The average intraocular pressure of HSO tamponade group was 20.233±8.007mmHg, and the average intraocular pressure of pre-operation group was 16.067±4.025mmHg, showing significant difference(t=-2.913, P=0.005).Between the pre-operation group and the HSO removed group 14.933±3.423mmHg, there was no significant statistical difference in the analysis of IOP (t=2.635, P=0.430).Anatomical success was achieved in 90% of cases after the removal of HSO.Most common complications were cataract formation and oil emulsification.CONCLUSION: Densiron-68 is a safe and effective tamponade material for the treatment of complex vitreoretinopathy.However, most common complications are cataract formation and oil emulsification.So clinicians should strictly handle indications and usage during the clinical applications.

Rhamnolipid,an important biosurfactant,is reviewed with respect to chemical strocture,properties,physiological role and their fermentation production,especially focusing on the production with inexpensive raw materials,such as vegetable oils and residues from agro- industrial wastes.This can not only reduce the production costs,but also contribute to the reduction of environmental impact generated by the discard of residues,and the treatment costs.
