ABSTRACT

Clinical data of 102 patients with premature ovarian failure admitted to Zhang Zhongjing Hospital from December 2018 to December 2021 were retrospectively analyzed. Fifty-one patients received (control group), and another 51 patients received Chinse medicine Kuntai capsule in addition to sequential estrogen progesterone therapy(study group); both groups were treated for 3 menstrual cycles. After treatment, the total effective rate of the study group was higher than that of the control group (94.1% (48/51) vs. 72.6% (37/51), χ2=4.07, P=0.044). After treatment, the proportion of patients with mild Kupperman score and serum estradiol level in both groups were increased, and the proportion in study group was higher than that in the control group. The proportion of patients with moderate and severe Kupperman score and the total score decreased after treatment in both groups, and the proportion of patients with moderate Kupperman score in the study group was lower than that in the control group. Serum luteinizing hormone and folliclestimulating hormone levels were significantly decreased, and the levels in study group were lower than those in the control group. The levels of resistance index and PI were significantly decreased after treatment in both group and the study group decrease more markedly (all P<0.05). The peak systolic flow velocity level was increased after treatment in both groups and the study group increased more markedly (all P<0.05). It is suggested that the application of Chinese medicine Kuntai capsule combined with sequential estrogen progesterone therapy can effectively improve the clinical therapeutic effect, stabilize sex hormones, uterine microcirculation and effectively alleviate the condition of patients with premature ovarian failure.

ABSTRACT

Introduction: Hutchinson-Guilford progeria syndrome (HGPS) is a rare genetic disease with a characteristic phenotype of premature aging in young children caused by a mutation in the LMNA gene and consequent accumulation of progerinin the cell. Aim: Describe oral manifestations of Hutchinson-Guilford progeria syndrome. Case Report: This is a case report of a six-year-old female patient with Hutchinson-Guilford Progeria syndrome. The physical examination revealed skin atrophy, lipodystrophy, hair rarefaction, prominent blood vessels of the scalp, craniofacial disproportion, perioral cyanosis and enlarged knee joints. The intraoral exam revealed limited mouth opening, mixed dentition with normal tooth anatomy and anteroinferior crowding. The eruption sequence and chronology were abnormal. The treatment plan included professional prophylaxis, the topical application of fluoride as well as both oral hygiene and dietary counselling. Monitoring the development of dentition and an early and timely dental intervention contributed to the maintenance of child's oral health. Conclusion: Early clinical and educational interventions can help patients with HGPS maintain adequate oral health status and improve their quality of life.

ABSTRACT

Abstract Cockayne syndrome is an autosomal recessive multi-systemic disorder due to DNA repair failure. It was originally described in 1936 in children of small stature, retinal atrophy and deafness, characterized by dwarfism, cachexia, photosensitivity, premature aging and neurologic deficits. The most typical feature is described as birdlike facies: protruding maxilla, facial lipoatrophy, sunken eyes, large ears and thin nose. Difficult airway management with subglottic stenosis and risk of gastric content aspiration has been described. Although the clinical characteristics of Cockayne syndrome have been well described in pediatric publications, there is only one report in the literature on anesthesia for an obstetric patient. We report the case of a pregnant patient diagnosed with Cockayne syndrome, submitted successfully to spinal anesthesia for a cesarean section due to cephalopelvic disproportion. In view of the difficult decision between inducing general anesthesia in a patient with a likely difficult airway, or neuraxial anesthesia in a patient with cardiovascular, respiratory and neurocognitive limitations, we suggest tailored management to reach the best results for the mother and newborn.


Resumo A síndrome de Cockayne é doença multissistêmica autossômica recessiva devido à falha no reparo do DNA. Originalmente descrita em 1936 em crianças com baixa estatura, atrofia retiniana e surdez, é caracterizada por nanismo, caquexia, fotossensibilidade, envelhecimento acelerado e déficits neurológicos. O mais típico é a fácies, descrita como similar à de um pássaro: maxila proeminente, atrofia do coxim adiposo bucal, olhos profundos, orelhas grandes e nariz fino. Tem sido descrita dificuldade no manejo da via aérea com estreitamento subglótico e risco de aspiração gástrica. Embora as características clínicas da síndrome de Cockayne sejam bem relatadas em publicações pediátricas, há apenas um relato de anestesia em paciente obstétrica na literatura. Relatamos o caso de gestante com diagnóstico de síndrome de Cockayne, submetida com sucesso a raquianestesia para parto cesariano por desproporção cefalopélvica. Diante da difícil decisão entre induzir anestesia geral em paciente com provável via aérea difícil ou anestesia neuroaxial, em meio a limitações cardiovasculares, respiratórias e neurocognitivas da paciente, conduta individualizada é sugerida para alcançar os melhores resultados para a gestante e o neonato.

ABSTRACT

Objective@#To summarize the clinical characteristics of 6 children with Hutchinson-Gilford progeria syndrome, and to analyze the pathogenic genes carried by some patients.@*Methods@#The clinical data of 6 patients were summarized. The pathogenic genes of 4 families were analyzed. Genomic DNA was extracted from 3ml of the subject′s blood with EDTA anticoagulation. The first-generation sequencing technology was used to analyze the sequence of Lamin A/C(LMNA) gene and to identify the pathogenic mutation sites by comparing with normal sequencing results.@*Results@#All the children had typical clinical manifestations of the disease which has been previously reported in the literature, such as severe growth retardation, special skin manifestations, and distinctive craniofacial manifestations.Gene sequencing results revealed that 2 patients carried classical heterozygous mutation of LMNA c. 1824C>T(p.G608G). The other two patients carried atypical mutations of LMNA IVS8-4 C>A and c. 1968+ 2T>C, among which the mutation of IVS8-4 C>A has not been reported.@*Conclusions@#In Chinese children, both classical and non-classical mutations in LMNA gene lead to the occurrence of premature aging. It is easy to make a diagnosis based on clinical manifestations. Finding of the pathogenic gene may further confirm the diagnosis.

ABSTRACT

Aging increases the risk of various diseases. The main goal of aging research is to find therapies that attenuate aging and alleviate aging-related diseases. In this study, we screened a natural product library for geroprotective compounds using Werner syndrome (WS) human mesenchymal stem cells (hMSCs), a premature aging model that we recently established. Ten candidate compounds were identified and quercetin was investigated in detail due to its leading effects. Mechanistic studies revealed that quercetin alleviated senescence via the enhancement of cell proliferation and restoration of heterochromatin architecture in WS hMSCs. RNA-sequencing analysis revealed the transcriptional commonalities and differences in the geroprotective effects by quercetin and Vitamin C. Besides WS hMSCs, quercetin also attenuated cellular senescence in Hutchinson-Gilford progeria syndrome (HGPS) and physiological-aging hMSCs. Taken together, our study identifies quercetin as a geroprotective agent against accelerated and natural aging in hMSCs, providing a potential therapeutic intervention for treating age-associated disorders.

ABSTRACT

Objective To observe the clinical efficacy of Bushen-Qingxin decoction for the patients with premature ovarian failure (POF) with kidney deficiency type. Methods A total of 120 POF patients were randomly divided into the observation group and the control group. The observation group were treated with Bushen-Qingxin decoction. The control group were treated with hormone replacement therapy (HRT). After continuous treatment for 3 courses, the clinical efficacy, clinical symptoms and the levels of estrogen (E2), luteotropic hormone (LH), follicle-stimulating hormone (FSH) were comparedbefore and after treatment. Results The total effective rate in the observation group was 86.7% (52/60), and the control group was 60.0% (36/60). The difference was statistically significant (x2=9.588, P=0.002) between two groups. The symptoms aversion to cold, and cold limbs, depressed mood, night sweats were improved significantly better than those in the control group(x2=16.464,16.214,11.525,9.938,P<0.001).After treatment,the serum E2(88.32 ± 9.35 pmol/L vs. 62.10 ± 7.22 pmol/L, t=17.848) in the observation group was significantly higher than this in the control group,while the serum FSH(32.33 ± 4.60 U/L vs.46.82 ± 5.47 U/L,t=15.704),LH(24.80 ± 3.37 U/L vs.32.16 ± 4.02 U/L, t=10.868) in the observation group were significantly lower than those in the control group (P<0.01). In the follow-up of 3 months, the recurrence rate in the observation group was 3.8% (2/52), but 16.7% (6/36) in the control group. The difference was statistically significant between two groups (x2=4.231, P=0.040).Conclusions The Bushen-Qingxin decocation can significantly improve the clinical symptoms and restore ovarian function.The Bushen-Qingxin decocation is an effective method for the treatment of premature ovarian failure.

ABSTRACT

Abstract: Werner syndrome is a rare autosomal recessive disorder, caused by mutations in the WRN gene. Clinical findings include: senile appearance, short stature, grey hair, alopecia, bird-like face, scleroderma-like skin changes, skin ulcers, voice abnormalities, cataracts, osteoporosis, type 2 diabetes mellitus, ischemic heart disease and hypogonadism. The syndrome begins to become apparent in adolescence but it is usually diagnosed in the third or fourth decade of life. Since the patients usually die by the age of 40-50 years related to malignant neoplasms or atherosclerotic complications, they should be closely followed and treated for complications

ABSTRACT

Objective To analysis the clinical features, diagnosis and treatment of Hutchinson-Gilford progeria syndrome (HGPS). Methods The clinical data and gene testing results of HGPS in two brothers in the same family were retrospectively analyzed. The related literatures were reviewed. Results The proband was 15 years old, and his younger brother was 6 years old. Both of them presented premature appearance at 4 years old and 1 year-old respectively. Both of them suffered from underweight, short stature, reduced subcutaneous fat, bird face (prominent eyes, facial skin, scalp veins exposure, hook and prominent nose, mandibular stenosis). In addition, their trunk and limbs skin was relaxation, and they had ankylosis,and shrill voice etc.In both of them,the compound heterozygous mutation of NBAS gene(c.4081C>T,c.5741C>T)were found by full sequence exon sequencing, which were inherited from their father and mother respectively. The literature review suggested that NBAS gene mutation was associated with the diseases with main phenotype of short stature and optic atrophy.Conclusions It is reported two cases of HGPS caused by NBAS gene mutation.It is rare that two brothers have HGPS.

ABSTRACT

La progeria es una enfermedad caracterizada por el envejecimiento prematuro en los primeros años de vida. El diagnóstico es fundamentalmente clínico y la supervivencia más allá de la adolescencia es inusual. En más del 80% de los casos la muerte se debe a complicaciones cardiovasculares. Se presenta el caso clínico de un paciente masculino de 26 años de edad, diagnosticado de progeria, que cursa internación por infarto agudo de miocardio ínfero-latero-dorsal con compromiso eléctrico y hemodinámico del ventrículo derecho. En resumen, los pacientes con progeria suelen presentarse con enfermedad coronaria a edades tempranas. Los registros de estos grupos de pacientes informan que la gran mayoría fallecen durante la adolescencia a causa de enfermedad coronaria. Mostramos un caso de un paciente joven con enfermedad coronaria severa que debuta con un infarto agudo de miocardio con resolución favorable.


Progeria: coronary artery disease and heart failure in a young patient Progeria is a disease characterized by premature aging in the first years of life. The diagnosis is essentially clinical and survival beyond adolescence is unusual. In over 80% of cases death due to cardiovascular complications. The case report of a male patient of 26 years old, diagnosed with progeria, coursing hospitalization for acute inferio-latero-dorsal myocardial infarction with electric and hemodynamic right ventricular involvement is presented. In summary, patients with progeria usually appear with coronary disease at early ages. The records of these groups of patients report that the vast majority die during adolescence due to coronary disease. We report a case of a young patient with severe coronary artery disease who presents with an acute myocardial infarction with favorable resolution.

ABSTRACT

Progeria is characterized by clinical features that mimic premature ageing. Although the mutation responsible for this syndrome has been deciphered, the mechanism of its action remains elusive. Progeria research has gained momentum particularly in the last two decades because of the possibility of revealing evidences about the ageing process in normal and other pathophysiological conditions. Various experimental models, both in vivo and in vitro, have been developed in an effort to understand the cellular and molecular basis of a number of clinically heterogeneous rare genetic disorders that come under the umbrella of progeroid syndromes (PSs). As per the latest clinical trial reports, Lonafarnib, a farnesyltranferase inhibitor, is a potent ‘drug of hope’ for Hutchinson-Gilford progeria syndrome (HGPS) and has been successful in facilitating weight gain and improving cardiovascular and skeletal pathologies in progeroid children. This can be considered as the dawn of a new era in progeria research and thus, an apt time to review the research developments in this area highlighting the molecular aspects, experimental models, promising drugs in trial and their implications to gain a better understanding of PSs.

ABSTRACT

Objective To study the gene mutations and clinical features of mandibuloacral dysplasia with type A lipodystrophy (MADA) in a Chinese family. Methods The information of 5 family members including 2 siblings suspected atyp-ical progeria was assembled. Genomic DNA was extracted from peripheral blood of 5 family members, the 12 exons of LMNA gene were ampliifed by PCR and then the PCR products were directly sequenced and analyzed by using Blast software online. The SIFT and PolyPhen-2 software were used to predict the harmfulness of mutations. Results The 2 siblings were clinically diagnosed as MADA. Heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations were detected in this family. The father carried c.1583C>T (p.Thr528Met) mutation, the mother carried c.1579C>T (p.Arg527Cys) mutation, and their normal daughter were all heterozygous carriers with c.1583C>T (p.Thr528Met) mutation. Compound heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations in 2 siblings led to MADA. The MADA showed an autosomal re-cessive inheritance pattern in this family. Conclusions The 2 siblings with MADA in this family were caused by compound heterozygous mutations in LMNA gene.
