A total of 17 cases with pelvic limb hyperhidrosis were selected for lumbar sympathetic nerve modulation.The puncture of lumbar sympathetic nerve was guided by computed tomography (CT) through the gap of L2-3 until the needle tip reached the lateral of the second or third lumbar vertebra body and outside of psoas major.A mixture of 1％ lidocaine 3 ml and 30％ Iohexol injection 0.3 ml was injected.If the diffusion of lidocaine was observed between lumbar vertebra body and psoas major.After 15 min,5 ml of absolute alcohol was injected to modulate the lumbar sympathetic nerve.After 5 min,oximetry-derived perfusion index of toe and sole temperature increased (5.9 ± 1.4) folds and (4.16± 0.89) ℃ on average respectively.Pelvic limb hyperhidrosis was all cured within 6 months and one case recurred after a year.There were no occurrences of complications.Lumbar sympathetic nerve modulation guided by CT may be used for treating female pelvic limbs hyperhidrosis.

Objective: To observe curative effect of radiofrequency catheter ablation (RFCA) and changes of cardiac function and left atrial diameter after operation in patients with atrial fibrillation (AF). Methods: A total of 28 AF patients with obvious clinical symptoms and without effective for drug therapy received RFCA in our hospital, their data were retrospectively analyzed. They received RFCA under guidance of three dimensional electro-anatomic mapping (EAM) system. Changes of cardiac function and left atrial diameter were evaluated by echocardiography and curative effect was evaluated by ambulary blood pressure monitoring before, three and six months after operation. Results: Pulmonary vein isolation rate was 100% in all patients. No severe complication occurred during or after operation. After six-month follow-up, 27 cases（96.4%）did not recur AF among the 28 patients; Compared with before operation, there were significant decrease in left atrial diameter [(37.3±4.8) mm vs. (33.6±4.5) mm] and significant increase in left ventricular ejection fraction [(59.8±8.7) % vs. (64.2±6.8) %] by echocardiography, P<0.05 both. Conclusion: Radiofrequency catheter ablation is safe and effective in treatment of atrial fibrillation, and there are significant improvements in cardiac function and left atrial diameter.

OBJECTIVE: To explore the clinical and genetic characteristics of a child with MEGDEL syndrome. METHODS: Clinical data of the child was reviewed. Peripheral blood samples of the child and his parents were collected. Mitochondrial genome and the whole exome of the child were analyzed by next-generation sequencing. Candidate variants and its origin were verified by Sanger sequencing and fluorescence quantitative PCR. RESULTS: The patient, a 2-year-and-6-month-old male, has featured hypoglycemia, mental and motor retardation with regression. Cranial MRI showed bilateral putamen damage suggestive of Leigh syndrome. Testing of urine organic acid indicated that the level of 3-methylpentenoic acid was slightly increased. Whole exome sequencing revealed that the child has harbored heterozygous deletion of exons 6 to 17 and c.307A>T nonsense variant of the SERAC1 gene, which were respectively inherited from his parents who were asymptomatic. Treatment with Levocarnitine, vitamin B1, vitamin B2, coenzyme Q10, baclofen and glucuronolactone resulted in improvement of sleep and mental state. CONCLUSION A case of MEGDEL syndrome without deafness was diagnosed. Discovery of the nonsense mutation and large fragment deletion have enriched the spectrum of SERAC1 gene variants.

Objective:To explore the motivation of the formation of the breastfeeding mission and education behavior of nurses in NICU, analyze the deep reasons, and construct the motivation and path theoretical model of the formation of the breastfeeding mission and education behavior of nurses in NICU.Methods:Through semi-structured interviews, the qualitative research method of grounded theory was used to study 20 nurses in the Second Affiliated Hospital, University of South China from July to September 2020, to construct the motivation and path theoretical model of the formation of the breastfeeding mission and education behavior of nurses in NICU.Results:The research identified five main categories: attitude factor, ability factor, behavior factor, internalization and externalization. Under the influence of three dimensions of attitude level, ability level and behavior level and their cross-layer interaction effects, the NICU nurses were driven to form stable breastfeeding mission and education behaviors through internalization and externalization.Conclusions:Based on the evolutionary context of "multi-dimensional factors and their interaction drivers-internalization-externalization", the relationship between attitude factors, ability factors, behavioral factors, internalization, and externalization are clarified. It provides a theoretical reference basis for managers in managing the breastfeeding propaganda and education of nurses in the NICU, and enriches the theoretical framework of breastfeeding behavior in the NICU.

Objective To understand the recognition and coping strategies of ICU nurses on post-ICU syndrome in family members of patients during hospitalisation so as to provide a reference for handling post-ICU syndrome of the family members of patients.Methods A phenomenological approach within qualitative research was adopted.Semi-structured in-depth interviews were conducted with 15 ICU nurses from 3 wards of the Second Affiliated Hospital of South China University.Colaizzi 7-step method was applied to analyse and refine the interview data themes.Results Three main themes and nine sub-themes were identified and they were insufficient cognition of post-ICU syndrome of the family members(limited understanding of post-ICU syndrome in family members,difficulty in recognising or ignoring symptoms,uncertainty about the impact of post-ICU syndrome),active coping with post-ICU syndrome of the family members(coping mainly through listening and explaining,coping mainly through verbal and physical actions,diligent patient care)and various factors hindering nurses'coping with post-ICU syndrome of the family members(compassion fatigue,high ICU work intensity,limited contact time with family members).Conclusion ICU nurses have insufficient understanding of post-ICU syndrome with the family members of patients during hospitalisation.It requires to enhance a comprehensive understanding in ICU nurses about post-ICU syndrome of the family members of patients and to optimise coping strategies to alleviate negative emotions of the family members.Additionally,efforts should be made to overcome factors that hinder nurses'coping with post-ICU syndrome of the family members of patients and to promote a harmonious relationship between medical staff and patients.

Psoriasis is a common immune-mediated inflammatory skin disease with multiple genetic and environmental risk factors.Abnormal vascular hyperplasia,excessive proliferation of keratinocytes and infiltration of various immune cells are the main pathological features.MAPK signaling pathway is involved in the pathogenesis of psoriasis,and SPRED1 has been proved to be a ma-jor negative regulator of MAPK signaling pathway in many diseases.This article reviews the possible role of SPRED1 in the pathogene-sis of psoriasis,in order to provide new insights into the pathogenesis of psoriasis and new directions for the treatment.

Systemic lupus erythematosus (SLE) is a multiorgan-involved autoimmune disease, and it can overlap organ-specific autoimmune diseases such as autoimmune thyroid diseases, autoimmune hepatitis and inflammatory bowel disease. There may be some association between SLE and these autoimmune diseases, such as common immunological and genetic basis, but the pathogenic mechanism is still unclear. This review focuses on current knowledge regarding the prevalence and possible pathogenesis of SLE overlapping the above three autoimmune diseases.
