ABSTRACT
Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant neurodegenera-tive disease rarely reported in China. Its symptoms include: cerebellar ataxia, epilepsy, dementia, myoclonus and choreoathetosis. We reported one case of adult-onset DRPLA family in the article. The female proband developed ataxia at the age of 45, followed by cognitive impairment and possible seizure. Five people in her family had similar symptoms. In addition, cranial MRI showed atrophy of the brainstem and cerebellar, as well as diffuse white matter lesions. Analysis of the ATN1 gene showed CAG repeat sizes to be 14/54 in the proband. Besides, we reviewed relevant literature published in recent years to improve the understanding of the disease, including its clinical manifestations, genetic characteristics, diagnosis and treatments.
ABSTRACT
Objective To explore the surgical procedures of reduction and lifting mammaplasty with the short vertical scar and breast lateral fibrous septum vascular pedicle to improve the clinical effect and reduce the complications.Methods Sixty-four patients underwent reduction and lifting mammaplasty:a incision around the areola and under the breast,using the breast lateral fibrous septum vascular pedicle and medial superior dermal pedicle to ensure the blood supply of the nipple.The skin and glands of the lower part of the breast were resected with suspension;upper part was lifting,with skin shaping and sutured.Results There were no postoperative complications such as hematoma,infection,skin and nipple areolar necrosis.The breasts were tall,plump and symmetry with little scar.Conclusions The breast reduction and lifting mammaplasty with breast lateral fibrous septum vascular pedicle and verical incision is effective in the treatment of macromastia and ptosis breast;breast form is satisfied and the complication is less;the operation is simple,safe,effective and worth promoting.
ABSTRACT
Objective To introduce our clinical method of filler injection with the posterior space of temporalis myofascia for temporal hollows,and to discuss the practical practicability,safety and aesthetic outcomes.Methods From Jan.2014 to Jan.2016,female patients with temporal hollows who had underwent the filler injecting into the posterior space of temporalis myofascia were involved in our study.The patients with previous history of surgery or trauma on temporal region were excluded.Hyaluronic acid or autologous fat was selected as filler material based on patients' preference.Then,aesthetic outcomes were followed up.120 cases were selected in this study.Among them,52 cases preferred hyaluronic acid,and the average follow-up time was 7.5 months.68 cases acceped autologous fat grafting with average follow-up for 9.5 months.Results All patients got aesthetic and safe outcome.No serious complications were noted,such as infection,embolism,uneven appearance and so on.The satisfactory rate was high in both patients and surgeons.Conclusions The posterior temporalis myofascia space that is relatively closed,stable,lack of vessels has proved to be the safe plane for temporal injection.Not only our injection method could meet the need for injection procedure safety,but also it could ensure the aesthetic outcomes.In clinical practice,the aesthetic surgeons should be well familiar with the temporal anatomy.
ABSTRACT
Objective To explore the biological functions of E77.43, a gene segment of Microtus fortis, in treating Schistoso-ma japonicum infection. Methods Recombinant retroviral vectors of pRevTRE-E77.43 was constructed, and recombinant retro-viral vectors were transfected into PA317 cells, and the stable cell lines were obtained by hygromycin screening, followed by the packaging, concentration and purification of recombinant retrovirus. The virus was transferred to the mice infected by S. japoni-cum via intravenous or intraperitoneal injection, through which the express of target gene and the treatment function in vivo were observed. Results The experiment showed the recombinant virus injected mice could efficiently express E77.43 on the 7th day after the injection which lasted for forty-five days thereafter. A significant reduction in adult worms (31.0％) and a high reduction (35.0％) in liver eggs were induced by pRevTRE-E77.43, while the reduction in adult worms and that in liver eggs was 1.2％and 0.9％induced by pRevTRE respectively (t=3.524, 9.485, both P<0.01). Conclusion pRevTRE-E77.43 could be used for the treatment of S. japonicum infection, indicating that E77.43 may involve in the natural resistance of M. fortis to S. japonicum infec-tion.
ABSTRACT
Objective To evaluate the design formulas of the optimal location for splitting pectoralis major in terms of making type Ⅰ or Ⅱ dual-plane implant pocket.Methods Sixty-five patients with micromastia were collected.Breasts were divided into two types according to the soft-tissue pinch thickness of the lower pole:type Ⅰ (thickness＞2 cm;34 cases) and type Ⅱ (thickness ≤2 cm;31 cases).The optimal levels at which the pectoralis major (PM) was severed were 3/4 or 2/4 of the distance of new inframammary fold for type Ⅰ or Ⅱ dual-plane pockets,respectively.All patients completed the pre-and post-operative BREAST-Q augmentation modules before and 6 months after surgery.The scores were changed into hundred-mark system by QScore software.Results The recovery processes were well-off.The breasts contour was good.Patients reported higher scores of satisfaction with breasts,psychosocial well-being and sexual well-being after surgery than before surgery (62.0±8.9 vs 27.9± 4.3,65.0± 17.2 vs 17.4±8.3,60.5± 14.2 vs 30.3±5.5,P＜0.05).The mean satisfaction score for the overall outcome was 90.6±5.4.However,there was no significant difference in physical well-being between before operation and aftre operation (85.3±9.5 vs 84.7± 10.6).No complications such as severe capsular contracture,or displacement occurred.Conclusions The design formulas make the determining procedure of the optimal location for pectoralis major splitting for two types dual-plane implant pockets easier and more exactly.Our modified design method can provide the implant with the optimal soft tissue coverage,and bring desired and stable breast aesthetic outcomes.The higher satisfaction and quality of life reported by patients indicate that the formulas are feasible and worth to recommend.
ABSTRACT
Cardiac output (CO) monitoring is a crucial part of the hemodynamic status monitoring. So far, thermodilution method, which is clinically recognized as the gold standard method to monitor cardiac output, still has irreplaceable advantages. This paper mainly introduces the use of platform for cardiac output measurement based on thermodilution method, mainly including three parts: the hardware platform, software design and algorithm process. A large amount of test data of this system has been got by CO simulator testing in the laboratory and preliminary clinical tests in the hospital. The testing result showed that using the proposed system can achieve good accuracy and repeatability.
