Aim To investigate the effects of silencing MALAT1 gene on cell proliferation inhibition and apop-tosis induced by Melittin in human hepatocellular car-cinoma HepG2 cells. Methods The inhibitory rate of cell proliferation treated with Melittin in HepG2 cells was examined by MTT assay. Apoptotic rate was detec-ted by flow cytometry. The MALAT1 expression level in HepG2 cells was measured by qPCR. Specific siR-NAs were utilized to silence MALAT1 expression. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were compared with those of Melittin alone. Results Melit-tin significantly suppressed the growth of HepG2 and induced cell apoptosis in a dose-dependent manner. Compared with normal liver cell lines, MALAT1 was highly expressed in HepG2 cells ( P<0. 05 ) . The ex-pression of MALAT1 in HepG2 cells was inhibited by Melittin, and the inhibitory rate increased with the in-crease of concentration. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were significantly higher than those treated merely with Melittin. Conclusion Melittin can reduce the expression of MALAT1 and silencing MALAT1 can effectively promote proliferation inhibi-tion and apoptosis in HepG2 cells induced by Melittin.

Objective To introduce a new method for correcting prominent malar complex deformity. Methods Through an intraoral incision, the highest area of zygomatic body marked preoperatively was grinded. Then an L shape incomplete osteotomy of the zygomatic body was performed with a reciprocating saw, and a complete osteotomy just 1 cm anterior to the articular tubercle of the zygomatic arch was made. Light pressure on the posterior part of the arch produced a greenstick fracture of the anterior osteotomy site, resulting in posterior-inward repositioning of the malar complex. Internal fixation was unnecessary. Results Operative procedures for reductive malar complex plasty were performed in 650 cases, which included 60 males and 590 females whose age ranged from 19 to 39 years.Incisions of all cases healed well. One case had maxillary sinusitis 2 weeks postoperatively, and recovered after 1 week by using antibiotics and drainage. There was 1 case with skin necrosis about 1 cm in diameter in the area of zygomatic body because of local liposuction, and the wound was healed by changing dressing. The forehead wrinkle of one side had disappeared in 1 case 1 week postoperatively, but had recovered 2 weeks later. Postoperative follow-up for 2-24 months showed satisfactory results.Conclusions This modified method has many advantages, such as simplicity, without internal fixation, short operation and recovery time, and little complications. The authors conclude that this technique is an effective and safe method of reduction malarplasty.
