Background:
In Asian women who undergo facelift procedures, satisfying results are achieved for facial rhytides, but sometimes there are postoperative complaints concerning the mandibular angle. Unlike Caucasians, Asians generally have a prominent mandibular angle. Accordingly, bone contouring surgery must be considered, since the bones of the face serve as the frame for facelift surgery. We investigated the effects of simultaneously performing mandibular angle reduction and facelift to achieve an oval facial contour and a youthful face.
Methods:
We evaluated 17 Asian women who simultaneously underwent mandibular angle reduction and facelift between April 2016 and May 2018. The clinical results were assessed based on preoperative and postoperative photographs and the Global Aesthetic Improvement Scale.
Results:
Surgery was successful in all cases. Postoperatively, improvements in facial rhytides and appropriate mandibular contours were achieved. All patients were satisfied with the outcomes. Some patients experienced short-term complications, such as hematoma and numbness of the skin above the incision line; however, these complications improved. Serious long-term complications were not noted.
Conclusions
Highly satisfying outcomes can be achieved with combined mandibular angle reduction and facelift for Asian women with a wide and rectangular face.

Archives of Aesthetic Plastic Surgery 2020;26(4):138-143
Background:
In Asian women who undergo facelift surgery, satisfactory results are typically achieved with regard to facial rhytides, but concerns have been reported regarding the postoperative appearance of the malar prominence region. Anatomically, compared to Caucasians, Asians have thick skin and a wide and short facial geometry. Asians generally exhibit zygomatic protrusion; accordingly, bone contouring surgery, which alters the base frame used in a facelift, should be considered. We aimed to investigate the effects of simultaneous reduction malarplasty and facelift to achieve appropriate malar repositioning and a youthful-looking face.
Methods:
We assessed 16 Asian women who underwent simultaneous reduction malarplasty and facelift between March 2014 and March 2018. The clinical results were assessed based on preoperative and postoperative photographs and Global Aesthetic Improvement Scale scores.
Results:
Surgery was successful in all cases. Postoperative improvement with regard to facial rhytides and appropriate malar repositioning were achieved. All patients were satisfied with the outcomes. Some patients experienced short-term complications, but their conditions improved. Serious long-term complications were not noted.
Conclusions
Highly satisfactory outcomes can be achieved with combined reduction malarplasty and facelift for Asian women with wide faces.

To assess the clinico-pathological characteristics of patients with multiple primary colorectal cancer, 458 patients who underwent curative surgery and being followed-up at our institution between Jan. 1987 and Dec. 1993 were evaluated in this study. The median follow-up period was 42 months. Synchronous cancer was defined as distinct lesions separated by a distance of greater than 4cm with the invasion of the tumor below the muscularis mucosa at the time of diagnosis or within 6 months after initial treatment, and metachronous cancer was defined as the development of colon cancers more than 6 months after the initial treatment without evidence of the recurrence or metastases from primary tumor. There were 29 cases of multiple primary colorectal cancer(6.3%). Eighteen cases(3.9%) of them were synchronous, 11 cases(2.4%) were metachronous cancers. Seven cases(1.5%) were related to 5 hereditary non-polyposis colorectal cancer(HNPCC) families. During the follow-up period, 11 patients(2.4%) developed cancers in other organs. Adenomatous polyps were identified 14 cases of 29 patients with multiple primary colorectal cancers(48.3%), compared to 43 cases(10%) in 429 patients with solitary colorectal cancer(p<0.01). After initial curative surgery, there were 8 recurrences in 29 patients with multiple primary colorectal cancers(23.6%), compared to 100 recurrences in 429 patients with solitary primary colorectal cancer(23.3%)(p>0.05). In aspect of family history, there was close-relationship with this regarding in the group of multiple primary colorectal cancers. However, authors were unable to make analysis this regarding in the group of solitary primaries because of lack of the information. Conclusively, authors guess the frequent association of the adenomatous polyps in multiple primary colorectal cancers as the evidence of the adenoma-carcinoma sequence. In addition, authors emphasized the importance of the total colonoscopic examinations in pre-and post-operation in order to make diagnosis of the multiple primary colorectal cancers and paying attention as to the family history of colorectal cancer patients because we have good therapeutic results after operation of early stage in synchronous cancers and co-existent adenomatous polyps.

We have expressed GFP in Sf9 and Bm5 cells or Bombyx by larvae by using Ac-Bm hybrid virus capable of replicating in both Bm5 and Sf9 cells. Genomic DNA of Ac-Bm hybrid virus expressing P-galactosidase was cotransfected with baculovirus transfer vector containing GFP gene, pBacPAK-GFP in Sf9 cells. The Ac-Bm hybrid virus harboring GFP was named as Ac-Bm hybrid virus-GFP. The Ac-Bm hybrid virus-GFP-infected insect cells were easily selected by detecting the emission of GFP from each well of cell culture dish on the UV illuminator. GFP produced by Ac-Bm hybrid virus-GFP in Sf9 and Bm5 cells or B. mori larvae was confirmed by SDS-PAGE and Western blot analysis using GFP antibody. In addition, B. mori larvae infected with Ac-Bm hybrid virus-GFP was apparently appeared fluorescence from the whole body at 5 days postinoculation. The fluorescence of GFP from the hemolymph and fat body of B. mori larvae infected with Ac-Bm hybrid virus-GFP was also observed by fluorescence microscope. In conclusion, our results demonstrated that in baculovirus expression vector system, use of Ac-Bm hybrid virus have an additional advantage of expanded host range for producing recombinant proteins.

The prognostic factors for extrahepatic biliary atresia (EHBA) after Kasai portoenterostomy include the patient's age at portoenterostomy (age), size of bile duct in theporta hepatis (size), clearance of jaundice after operation (clearance) and the surgeon's experience. The aim of this study is to examine the most significant prognostic factor of EHBA after Kasai portoenterostomy. This retrospective study was done in 51 cases of EHBA that received Kasai portoenterostomy by one pediatric surgeon. For the statistical analysis, Kaplan-Meier method, Logrank test and Cox regression test were used. A p value of less than 0.05 was considered to be significant. Fifteen patients were regarded as dead in this study, including nine cases of liver transplantation. There was no significant difference of survival to age. The age is also not a significant risk factor for survival in this study (Cox Regression test; p = 0.63). There was no significant difference in survival in relation to the size of bile duct. However, bile duct size was a significant risk factor for survival (Cox Regression test; p = 0.002). There was a significant difference in relation to survival and clearance (Kaplan-Meier method; p = 0.02). The clearing was also a significant risk factor for survival (Cox Regression test; p = 0.001). The clearance of jaundice is the most significant prognostic factor of EHBA after Kasai portoenterostomy.
