The aim of this study was to observe whether necroptosis is involved in the process of cardiac hypertrophy induced by pressure overload. SD rats underwent transverse abdominal aortic constriction (TAC) operation for establishing cardiac hypertrophy model. The structure and function of the left ventricle of rats were evaluated via echocardiography, left ventricular mass index, the expression of markers of cardiac hypertrophy and histological detection. Real-time PCR and Western blot were used to measure the gene and protein expression of receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3, the necroptosis markers) respectively. Four weeks after TAC operation, rat model for cardiac hypertrophy was established. The experimental data showed that the gene and protein expressions of RIPK1 and RIPK3 in the rat heart hypertrophic tissues after TAC for 4 weeks were increased significantly compared with those in the sham group. HE staining showed cardiomyocytes injury and hypertrophy in the hearts of TAC rat models. By transmission electron microscope, we observed that mitochondria of cardiomyocytes were damaged seriously in the TAC models. Treatment with losartan used, the selective antagonist of angiotensin II type I receptor could improve the cardiac function of TAC rats. Moreover, losartan treatment decreased the expression of RIPK1 and RIPK3 in heart tissues of TAC rats. The results suggest that necroptosis occurrs in the process of cardiac hypertrophy with pressure overload, and losartan could alleviate the cardiac hypertrophy and inhibit necroptosis.

Objective:To compare the pros and cons of harvesting ear cartilage through anterior and posterior auricular approaches during rhinoplasty.Methods:From January 2017 to December 2018, 63 patients with otochondral rhinoplasty in our hospital were enrolled in this study, 60 were female and 3 were male; the average age was 31.6 years (range, 18 to 43) . They were randomly divided into anterior auricular approach group with 32 cases (64 sides) and posterior auricular approach group with 31 cases (62 sides). Surgical duration, complications and postoperative scar of the two methods were analyzed.Results:The average time for harvesting the ear cartilage through posterior auricular approach and anterior auricular approach was (20.8±1.7) min and (12.6±1.1) min, respectively ( P<0.01). The overall complication rate was 15.6% for posterior auricular approach group and 4.8% for anterior auricular approach group. The wound healed well in both groups, and there was no significant difference in postoperative scar between the two groups during an average 13 months follow-up period. Conclusions:While both the anterior and the posterior auricular approaches present with similar inconspicuous scarring, the use of anterior auricular approach alone to harvest ear cartilage during rhinoplasty provides both the surgeons and the patients with easier access, shorter surgical duration, and fewer complications. Hence, we believe that the anterior auricular approach possesses greater advantages than the posterior auricular approach.

Objective:To explore the classification and treatment strategies of developmental breast asymmetry (DBA).Methods:A retrospective study was conducted in adult female patients with developmental breast asymmetry deformity who underwent surgery between January 2005 to June 2019 in the Plastic Surgery Department of Peking Union Medical College Hospital. According to different clinical manifestations, DBA was divided into three types which adopted to different surgical strategies. Postoperative complications and patient satisfaction were evaluated.Results:A total of 203 patients were included in the study; 42.36% (86 cases) were type Ⅰ, 31.03% (63 cases) were type Ⅱ and 26.60% (54 cases) were type Ⅲ. The number of follow-up patients accounted for 79.3% (161/203). The mean follow-up time was 9 months. There were one case of poor healing of the axillary incision in latissimus dorsi muscle flap, two cases of seroma, five cases of Baker grade Ⅰ capsule contracture, two cases of Baker grade Ⅱ capsule contracture and one cases of small nodules in autologous fat breast augmentation. With regard to patient satisfaction, 80.1% (129 cases) felt satisfied with the aesthetic results, 15% (24 cases) felt good, 3.7%. (6 cases) felt average and 1.2% (2 cases) felt unsatisfied.Conclusions:This study shows that the clinical manifestations of DBA are varied, and our classification method is an effective and useful tool to guide the surgical treatment. Individualized surgical design is essential for aesthetical results.

Objective:
To observe the anatomical layers and important vascular structures in the main periorbital regions of the human body, and to provide some anatomical basis for clinical periorbital fat injection.
Methods:
During January 2018 to December 2018, 12 (24 sides) cadavers (6 males and 6 females, 47.5±11.7 years old) were selected. Their orbital tissues were dissected routinely and microdissected. The important blood vessels and tissues around the orbit were measured by electronic vernier caliper. The related matters needing attention in fat injection filling were analyzed according to references.
Results:
The main structural areas around the orbit included eyelid, eyebrow and lacrimal groove deformities. The thickness of eyelid skin was (0.09±0.03) mm. The thickness of eyebrow skin was (3.45±0.38) mm. Vascular (diameter ranged from 1 mm to 3 mm) distribution was abundant in this area. The inner diameter of dorsal nasal artery, supraorbital artery and trochlear artery were (0.73±0.42) mm, (0.88±0.37) mm and (0.71±0.51) mm respectively. Facial artery, maxillary artery and superficial temporal artery with internal diameters of (2.96±0.88) mm, (1.92±0.33) mm and (1.35±0.15) mm, respectively.
Conclusions
The entrance of upper eyelid injection is usually in the eyebrow tail or middle eyebrow, and fat is injected into the deep surface of orbicularis oculi muscle. The injection range is limited to the medial 2/3 of upper eyelid, the medial 1/3 of lower eyebrow and the lateral part of eyebrow. It is suggested that single layer microinjection of fat (0.5 ml to 1.5 ml) could be used. Lower eyelid fat transplantation is mainly used to correct deformities at the eyelid-cheek junction. The aim is to reduce the V-shaped deformity at the eyelid-cheek junction by increasing the fullness. Injection can be made by blunt needle into the inner, outer and middle part of the deformity. Fat can be injected into SOOF layer or periosteum in the palpebral and cheek sulcus area. The injection volume is 0.5-1.0 ml.
