Objective To explore the application of the part of the orbicularis oculi muscle above the cutting margin and the orbital septum fixed to pretarsal fascia in construction of double eyelid.Methods We selected 30 aesthetic seekers asking for construction of double eyelid.We fixed the part of the orbicularis oculi muscle above the cutting margin and the orbital septum to pretarsal fascia in double eyelid operation and then evaluated the surgical effects,complications and satisfaction.Results 30 cases were successfully operated in this group,and the operation time was 1.0 ±0.2 hour.Five days after operation,we removed upper eyelid skin suture and observed that wound healing was good and double eyelid line was natural and smooth.Postoperative follow-up of 1 to 6 months,the effects were satisfactory.Conclusions This method is simple and effective in producing a satisfactory eye shape.

Objective: To propose updates and amendments for the nitroglycerin tablets quality in the Chinese pharmacopoeia 2020 due to the failure of effective separation of 4 known impurities and nonseparation of free nitrate ion and excipients.
Methods: Related substances were analyzed using gradient elution by HPLC, and free nitrate ion was determined on SAX column by different HPLC method.
Results: Using the improved method to test the related substances and free nitrate ion of nitroglycerin tablets,the content of the maximum individual impurity were not more than 0.5%, the total content was not more than 2.4% and the content of free nitrate ion was not more than 6.3%.
Conclusion: The improved method is accurate and feasible. It provided a reference for the updates and amendments of the quality standard of nitroglycerin tablets in the Chinese Pharmacopoeia 2020.

Objective To study the safety of transfusion of itraconazole through PICC and to evaluate the effect of different amount of blood transfusion before and after the infusion. Methods Patients were recruited from January 1, 2014, until December 31, 2015, in the Hematology hematopoietic stem cell transplantation ward. Thiry-two patients were recruited in the control group. Ninety patients wererecruited in the experience group. They were randomly assigned to three groups with 30 cases each, extracting different amounts of itraconazole before infusion, back phlebotomize in group A, B, C respectively was 10.0, 0.5, 1.0 ml. Comparing the phlebitis and obstruction after ten days from the transfusion day on. Results Catheter obstruction was not observed in any case. There was a significant difference between control group (21.9%,7/32) and observation group (0) regarding the incidence of phlebitis (χ2=21.157,P < 0.05). No statistical difference was noted among the observation groups regarding the incidence of phlebitis (P>0.05). Conclusions Drawing a small amount of blood volume before itraconazole injection through PICC can effectively avoid the drug-induced catheterobstruction. What′s more, transfusion through PICC can significantly reduce the incidence of phlebitis compared with peripheral infusion.

OBJECTIVE: To observe the effect of luteolin on the proliferation and expression of OPCML in breast cancer cell line MDA-MB-231. METHODS: Cultured MDA-MB-231 cells were treated with luteolin at the concentrations of 5, 10 and 20 μmol/L for 24 or 48 h. MTT assay was used to detect cell proliferation and flow cytometry was used to detect the cell apoptosis. The expressions of OPCML mRNA and protein were detected using real-time quantitative PCR and Western blotting, respectively. OPCML gene methylation in the promoter region was detected using methylation-specific PCR (MSP), and the activity of methylase in the cells was analyzed. RESULTS: MTT assay showed that treatment with luteolin at 5, 10 and 20 μmol/L for 24 h concentration-dependently decreased the viability of MDA-MB-231 cells ( < 0.05). Flow cytometry also showed that luteolin at different concentrations could induce apoptosis of MDA-MB-231 cells ( < 0.05). Luteolin dose-dependently induced the expression of OPCML mRNA and protein in MDA-MB-231 cells ( < 0.05), down-regulated the methylation status in the promoter region of OPCML gene, up-regulated the level of non-methylated OPCML, and reduced the activity of methylase in the cells ( < 0.05). CONCLUSIONS Luteolin inhibits the proliferation of MDA-MB-231 breast cancer cells probably by upregulating OPCML expression and its demethylation.

OBJECTIVES: The objectives of this study were to assess the quality of prosthetic prescriptions of removable partial dentures (RPDs) and to analyze the current situation of the communication and information delivery between clinicians and technicians. METHODS: All RPD prosthetic prescriptions received by a major dental laboratory in 4 weeks were involved in a quality audit, and the prescriptions were divided into three groups in accordance with the grades of clients. The filling of prosthetic prescriptions was recorded. The items in the prescriptions for audit included the general information of the patient, the general information of the clinician, the design diagram information, other detailed information, and the return date. The prescriptions were categorized into four levels on the basis of their quality by two quality inspectors who have been working for more than 10 years. RESULTS: A total of 916 prescriptions were collected and assessed. The names in the general information of the patient and the clinician were filled out best, both at the rate of 97.6% (n=894). The return date was filled out worst, only at the rate of 6.4% (n=59). Of those prescriptions, 86.8% (n=795) exhibited inadequate design diagram information. The results of the quality assessment demonstrated that 74.2% of prescriptions were assessed as noncompliant ones and failed to meet the acceptable clinical quality standard. CONCLUSIONS At present, the overall quality of RPD prosthetic prescriptions is poor. The responsibilities of clinicians and technicians are unclear, and the communication between them is not ideal.
