Objective To discuss a simple and effective method of medial epicanthoplasty with the subcilliary incision, which can decrease the visible scar. Methods From January of 2007 to De-cember of 2008, 38 patients with epicanthal fold underwent epicanthoplasty using the new method. During the operation a skin incision was subcilliarily made outward from the original medial epican-thus. After elevating the flap and excising the orbicularis oculi muscle beneath the epieanthal fold, the new medial epicanthus was sutured to the designed point. Then subciliary incision was trimmed and sutured. Results Most of the patients obtained satisfactory results. Only one patient complained a-bout visible scarring and none required revision surgery. Scarring was avoided on the noticeable medial canthal region because the only incisions needed were subciliary incisions. Conclusions This method is simple to design and easy to perform. The operative results are effective without visible scars on the medial canthal region.

Objective: To observe the effects of He-Ne laser on the expression of extracellular matrix and its regulatory factors in degenerated temporomandibular joint(TMJ) of rabbits. Methods: 40 New Zealand adult white rabbits were randomly divided into normal group,sham model group,TMJOA model group and laser treatment group(n = 10),the rats in treatment group were treated by He-Ne laser irradination at acupoints. The rats in each group were divided into 1 d and 11 d groups(n = 5). The animals were respectively killed 1 d and 11 d after operation and HE staining was used to observe the histomorpholy. The protein expression of extracellular matrix and its regulatory factors were examined by Western blot. Results: After He-Ne laser treatment,the fiber layer of condylar cartilage was slightly loose,part of the fiber was newly produced. The level of Col-2,PRG-4,TIMP-1,BMP-2 was up-regulated and the of MMP-13 was down-regulated in the 11 d treatment group. Conclusion: He-Ne laser irradiation on acupoints may up-regulate the expression of extracellular matrix (Col-2 and PRG-4) and its regulatory factors (TIMP-1 and BMP-2),down-regulate the expression of MMP-13.

Objective To observe the clinical efficacy of irinotecan combined with capecitabine or tegafur-gimeracil-oteracil potassium in the second-line treatment of advanced colorectal cancer. Methods The clinical data of 19 patients with advanced colorectal cancer who were admitted to the Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from October 2014 to December 2017 were retrospectively analyzed, and these patients failed the first-line chemotherapy regimen. All patients were treated with irinotecan plus capecitabine or tegafur-gimeracil-oteracil potassium. The patient's short-term efficacy, adverse reactions, progression-free survival, and overall survival were analyzed. Results After treatment, the efficacy in 18 of the 19 patients with advanced colorectal cancer was evaluable, including partial remission in 3 patients, stable disease in 13 patients, and disease progression in 2 patients. The objective remission rate was 16.7% (3/18), the disease control rate was 88.9% (16/18), the median progression-free survival time was 7.6 months, and the median overall survival time was 23.3 months. All of the patients were well tolerated , and the grade 4 adverse reaction was presented as grade 4 neutropenia (1 case), grade 3 leukopenia (2 cases) and thrombocytopenia (1 case), grade 2 diarrhea (1 case), and grade 1 diarrhea (3 cases), and grade 1-2 liver injury (3 cases) and nephrotoxicity (2 cases). Conclusion Irinotecan combined with capecitabine or tegafur-gimeracil-oteracil potassium in the treatment of advanced colorectal cancer is effective and safe, which is worthy of clinical promotion.

Objective:To compare the postoperative effects of double eyelid surgery with different exophthalmos to find its influence on the surgery and necessary changes in preoperative design and during operation.Methods:A total of 50 female patients with single eyelid seeking beauty from June 2021 to March 2022 were selected from the Department of Plastic Surgery, Affiliated Hospital of Qingdao University. The ocular protrusion was measured by HETEL ophthalmostatometer before surgery. Both eyes at 12-15 mm were taken as normal group ( n=26), both eyes at 16-18 mm as mild protrusion group ( n=14) and both eyes at 19-22 mm as severe protrusion group ( n=10). All the patients were treated with double-eyelid surgery by orbital septum and unified postoperative nursing. Results:After six months of follow-up, there was no difference in eyelid width with closed eyes (all P>0.05). The width of double eyelid with open eyes in normal group was smaller than that in mild protrusion group ( F=23.23, all P<0.05), and the width of double eyelid with open eyes in mild protrusion group was smaller than that in severe protrusion group ( F=47.70, all P<0.05). There was no difference in the improvement rate of facial aesthetics among the three groups ( P>0.05). The " feeling of meet" and scar formation in the normal group were less than those in the mild protrusion group ( F=16.92, F=33.45, all P<0.05), and the " feeling of meet" and scar formation in the mild protrusion group were less than those in the severe protrusion group ( F=27.93, F=28.53, all P<0.05). The improvement rate of normal group was higher than that of mild and severe protrusion group (χ 2=7.25, 7.89, all P<0.05). There was no difference in the improvement rate between the mild and severe protrusion groups ( P>0.05). Conclusions:In clinical practice, it is necessary to make corresponding changes in the preoperative design and operation of double eyelid surgery for patients with high eyeball protrusion.
