Study of the correlations between loneliness, disease uncertainty, and perceived social support among elderly patients with digestive tract tumors during treatment.

Objective: To explore whether there are correlations between loneliness, disease uncertainty, and perceived social support among elderly patients with digestive tract tumors.

Method: A cross-sectional study was conducted on 149 patients with digestive tract tumors. A general information questionnaire, the Chinese version of the Cancer Patient Loneliness Scale, the Disease Uncertainty Scale, and the Perceived Social Support Assessment Scale were used.

Salvianolic acid B protects against UVB-induced skin aging via activation of NRF2.

Background: Prolonged exposure to sun radiation may result in harmful skin photoaging. Therefore, discovering novel anti-photoaging treatment modalities is critical. An active component isolated from Salvia miltiorrhiza (SM), Salvianolic acid B (Sal-B), is a robust antioxidant and anti-inflammatory agent.

Salvianolic Acid B Attenuates Hypertrophic Scar Formation In Vivo and In Vitro.

Background: Hypertrophic scars (HTSs) are a fibroproliferative disorder that occur following skin injuries. Salvianolic acid B (Sal-B) is an extractant from Salvia miltiorrhiza that has been reported to ameliorate fibrosis in multiple organs. However, the antifibrotic effect on HTSs remains unclear.

Salvianolic Acid B Reduces the Inflammation of Fat Grafts by Inhibiting the NF-Kb Signalling Pathway in Macrophages.

Background: Autologous fat grafting is a common method for soft tissue defect repair. However, the high absorption rate of transplanted fat is currently a bottleneck in the process. Excessive inflammation is one of the main reasons for poor fat transplantation.

The effect of glycerol as a cryoprotective agent in the cryopreservation of adipose tissue.

Background: Long-term preservation of adipose tissue is crucial for clinical applications. Researchers should consider both efficiency and biosafety when choosing a cryoprotective agent (CPA) for adipose tissue preservation. Glycerol has been applied as a nontoxic CPA for multiple tissues but not adipose tissue.

Salvianolic acid-B improves fat graft survival by promoting proliferation and adipogenesis.

Background: Our previous study proved that Salvia miltiorrhiza could enhance fat graft survival by promoting adipogenesis. However, the effect of salvianolic acid B (Sal-B), the most abundant and bioactive water-soluble compound in Salvia miltiorrhiza, on fat graft survival has not yet been investigated.

Objective: This study aims to investigate whether salvianolic acid B could improve fat graft survival and promote preadipocyte differentiation.

[The significance of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts].

Objective: To investigate the significance and images characters of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts(FTB).

Methods: From June 2005 to June 2012, 13 cases with 96 fat necrosis lumps after FTB, were retrospectively reviewed. The pre-operative images of ultrasound and mammography, as well as the post-operative histologic results were collected.

Treatment of breast injection with polyacrylamide hydrogel with infiltrated fascia capsule removal: report on 104 cases.

Background: Complications of polyacrylamide hydrogel injection for augmentation mammaplasty have captured the attention of both medical experts and the general public in China. Increasing numbers of patients are seeking to have the polyacrylamide gel removed from their breasts regardless of whether they suffer from symptoms. Blunt aspiration, which is widely performed but removes only free hydrogel, leaves residual hydrogel in the breast.

[Integrated autologous fat graft in face recontouring].

Objective: To discuss the integrated autologous fat graft technique in face recontouring.

Methods: In this study we treated 83 cases of face recontouring with 3L3M technique (low pressure suction, low speed centrifugation, low volume, multi-plane, multi-tunnel, multi-point injection). Each case was treated 1-3 times and the interval period is 3-6 months.

Transplanted endothelial progenitor cells increase neo-vascularisation of rat pre-fabricated flaps.

Background: Flap pre-fabrication is dependent on the eventual re-vascularisation of the implanted vascular carrier and the presence of a desirable, donor-skin site. However, insufficient neo-vascularisation and subsequent necrosis is an obstacle for this technique. A recent discovery demonstrated that endothelial progenitor cells (EPCs) augment post-natal neo-vascularisation in ischaemic tissues.

An integrated fat grafting technique for cosmetic facial contouring.

Background: Although several methods of fat grafting have been reported, there is no agreement regarding which technique should be used for autologous fat grafting and the final outcome after fat grafting often depends on the technique used by a surgeon. In this report we present an integrated fat grafting technique developed over the years for cosmetic facial contouring.

Method: Fat grafts were harvested under low pressure with syringes, processed with low speed centrifugation, and then injected into the affected areas of the face with low volume for each pass via multi-tunnels, multi-planes, and multi-points.

Autologous fat grafting to the breast for cosmetic enhancement: experience in 66 patients with long-term follow up.

Background: Autologous fat grafting to the breast for cosmetic enhancement remains controversial because the efficacy and fate of fat grafting to the breast are primarily unknown. In this report, we present our retrospective study in 66 patients who underwent autologous fat grafting to the breast for various cosmetic reasons and who were followed with sonography, mammography, or magnetic resonance imaging (MRI).

Methods: Sixty-six patients who desired cosmetic enhancement of the breast for various reasons underwent autologous fat transplantation between August 2000 and March 2005 in our institution.

[Three case reports of abdominal compartment syndrome after full abdominoplasty].

Objective: To improve the safety of the abdominoplasty by the study of the complication of abdominal compartment syndrome after abdominoplasty.

Methods: Three cases were analyzed and discussed respectively in aspects of clinic symptoms, pathological reason, treatments and follow-up results. The treatment was the incision of musculoaponeurotic system, which usually cause defect of abdominal wall after pressure releasing.

[Application of aesthetic sub-unit principle in nasal reconstruction and repairing of nasal defects].

Objective: To evaluate the significance and effect of nasal aesthetic sub-unit principle.

Methods: Based on nasal aesthetic sub-unit, 27 patients were divided into 5 groups according to their nasal defects. They were nasal dorsum, tip, alar lobule, soft triangle and two or two above nasal subunit defects groups.

[Research of the preservation of the composite facial allograft].

Objective: To investigate the effective method of preserving composite facial allograft so as to attenuate ischemic injury.

Methods: The composite facial allografts were harvested from dog, perfused and preserved with 4 degrees C physiological sodium chloride and UW solution respectively. Immediately after the removal of the flap, after 12, 24, 48 h of preservation, MTT assay was used to determine the viability of several kinds of tissue, including skin, mucosa, muscle, bleed vessel, nerve and gland.

[Establishment of composite facial and scalp allograft transplantation model in canine].

Objective: To develop an experimental model of composite facial and scalp allograft in canine in order to investigate technical and immunological aspects and functional recovery of facial muscles of this new approach to facial reconstruction.
