ABSTRACT
Stromal vascular fraction(SVF)are the remaining cells after removing mature fat cells in the adipose tissue. Containing a certain amount of adipose derived stem cells(ADSCs), SVF also includes many other cells, which may have the potential of promoting angiogenesis. In this review, the role of SVF in angiogenesis after fat transplantation was summarized by intensive reading relative literature in recent years. The result is that angiogenesis and fat graft revascularization are regulated by various factors: SVF promotes secretion of a diverse array of cytokines and growth which are capable of stabilizing endothelium vascular network. ADSCs have the potential of differentiating into smooth muscle cells and endothelial cells which can coroperate to form new blood vessels.
ABSTRACT
Objective@#To evaluate the effect of vertical incision with superomedial pedicle for the treatment of female asymmetric hypermastia.@*Methods@#The total of 31 patients with asymmetric breast hypertrophy were admitted from May 2012 to November 2018. All patients were female with an average age of 37.8 (28-55) years. Mammoplasty was performed by vertical incision with superomedial pedicle. According to the preoperative design, the epidermis of the pedicle, the excess skin and glandular tissue were removed. The superomedial pedicle was rotated upward and to be fixed on the major pectoralis fascia. After the fixation of the nipple areola, the incision was closed.@*Results@#The mean follow up was (8.4±3.0) months, with a range from 6 to 18 months.One patient was unsatisfied with scar hyperplasia. One patient had slight mastoptosis 6 months after operation and received favorable outcome after revision. The rest of 29 patients had satisfactory results.@*Conclusions@#For patients with asymmetric breast hypertrophy, the new location of nipples on both sides should be determined by the degree of mastoptosis and hypermastia. So that, symmetry breast as well as smaller breast can be obtained.
ABSTRACT
Objective To understand the dynamics of the treatment and outcomes of advanced schistosomiasis patients in Qianjiang City so as to provide the evidence for improving the future work. Methods All advanced schistosomiasis patients were investigated in Qianjiang City during the period of 2009-2013. Results Totally 1 284 person?times of advanced schistoso?miasis patients received the treatment. The rate of clinical improved was 89.88% and 82 patients were cured. The type of asci?tes was the majority and the megalosplenia type was the second. Conclusion The prevalence of advanced schistosomiasis showed a decreasing tendency but the incidence of new advanced schistosomiasis patients showed a slightly increasing.
ABSTRACT
Objective To investigate the occupational risk awareness levels of higher vocational nursing students before and after the clinic practice.Methods Five-year higher vocational nursing students were investigated by filling out questionnaires before and after the clinic practice.Results Nursing students' occupational risk awareness improved after the clinic practice.They hoped to acquire knowledge about occupational risk and thought that the school was supposed to offer professional ethics courses and strengthen the occupational risk education.Conclusions The majority of nursing students knew the protective measures of occupational exposure in nursing.But there were also someone who did not know these.Relevant knowledge was in high demand.Therefore,schools and internship units should provide a variety of ways to reduce the risks during the internship of nursing students.
ABSTRACT
Objective To discuss a new method on treatment of the nephroptosis. Methods Seven patients of nephroptosis were treated with polypropylene ventrofixation on the twelfth rib.There were 2 male cases and 5 females.The patients aged from 14 to 46 years old.Height were a-mong 150 and 183 cm and weight from 45 to 68 kg.There were 5 cases with right side lesions,l case left and 1 case bilateral.The operation was performed through the lumbar incision.A polypropylene net string was put betw,een the fibrous capsule of the kidney and the adipose capsule,across the lower pole of the kidney.After adj usted the tension,the string was fixed by silk suture or by rivet after the silk running around the twelfth rib.IVU(intravenous urogram)was performed to compare the posi-tion of kidney pre-and post operation. Results The operations were successfully done.Averagc time of the operation was 65 min(from 50 to 90 min)and average hospital stay was 8 d(from 7 to 9 d).Average time lying in bed was 7 d(between 6 and 8 d).The symptoms of waist soreness.1umbo-dynia,hematuria,frequent micturition relieved.The follow up time was from 1 2 to 3 6 months with an average of 24 months. In 4 cases of hydronephrosis and calculus,3 cases were cured and 1 case was lightened.One case of repeated urinary tract infection,urinary sediment was normal and irritation symptoms disappeared.For l case with Dietl syndrome,the symptoms of nephric colic,nausea,pal-lor,exhaustion,hematuria disappeared. Conclusion The Polypropylene ventrofixation on twelfth rib might be alternative treatment choice for nephroptosis.
