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.

This paper reports a case of reparing the tissue defect after resection of a malignant tumor in the glabellar nasion with bilateral modified horizontal advancement flaps. The patient, a 20-year-old female, was admitted to the hospital because of a mass on the nasion between the eyebrows for more than 5 years, with enlargement and ulceration for 5 months. Surgical resection of the tumor was performed. Intraoperative rapid frozen sections showed that the tumor was basal cell carcinoma, and there were no cancer cells at the margins. Bilateral modified horizontal advancement flap repair was performed. At three months after the operation, the incision area healed well, the appearance and eyelid function were normal, and there was no sign of recurrence of basal cell carcinoma. Bilateral modified horizontal advancement flap was effective in repairing the tissue defect after resection of glabellar nasal root basal cell carcinoma.

Objective:To explore the surgical effects of continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty.Methods:A retrospective study was conducted on patients who underwent the operation of continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty at the Department of Plastic and Aesthetic Surgery of Qingdao Municipal Hospital from September 2021 to September 2023. Six points were marked on the skin surface of the designed double eyelid line on patient' s upper eyelid, 8 points were marked on the corresponding conjunctival surface of the designed double eyelid line. A 6-0 nylon thread attached with one needle on each end was used for suturing, with two ends running through and between the subcutaneous and subconjunctival layers alternatively, forming a " trapezoidal" shape of path. Finally, two ends exited at the same point on the most lateral side of the designed double eyelid line on skin surface and were tied together with the knot hidden within the orbicularis oculi muscle. The morphology of the double eyelids and postoperative complications were observed and evaluated after surgery, the follow-up period was at least 6 months. At the last time of follow-up, the satisfaction rates were evaluated by patients themselves. Four aspects of the surgical effects of the double eyelids were put into the evaluation system, which were radian, width, smoothness and symmetry, with score from 0-5 points for each. The total score was 0-20 points, of which 17-20 points indicated high satisfaction, score of 13-16 points indicated relative satisfaction, ≤ 12 points indicated dissatisfaction.Results:A total of 52 female patients were included, aged 18 to 29 years old, with an average age of 22.5 years. Among all patients, 33 cases had shallow double eyelid lines while 19 cases had single eyelids. All patients’ upper eyelids were relatively thin and without obvious looseness. The surgical procedures were all done smoothly and successfully, with an average operation time of (0.72±0.13) h. Immediately after surgery, the radian of the double eyelid lines on both sides looked smooth, the widths of the double eyelids were also basically symmetrical. During the follow-up period of 6-12 months postoperatively, the morphologies of the double eyelids were relatively natural and realistic, the double eyelid lines and widths remained deep and stable, and the incision scars were left unobvious for all patients. Besides, no complications such as ptosis, incomplete upper eyelid closure and ectropion were observed. Among the 52 patients, 45 cases were highly satisfied with the surgical result (17-20 points) , 7 were relatively satisfied (13-16 points) , while none of them required reoperation.Conclusions:The continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty has advantages of short operation time, good and stable surgical effects such as natural and realistic morphology of double eyelids, few complications, and high patients' satisfaction rate.

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.
