ABSTRACT

Objective:To enhance understanding of mental retardation autosomal dominant 35 (MRD35) by analyzing the clinical and genetic characteristics of the disease.Methods:Clinical and genetic data of 1 case of MRD35 in Beijing Children′s Hospital in July 2018 were reported, and literature review was conducted.Results:The male proband, 1 year and 3 months old, was admitted with the clinical manifestations including mental retardation, low-grade fever, a large forehead, flat nose, open mouth, and hypomyotonia. The brain magnetic resonance imaging showed enlarged lateral ventricles, cavum septum, cavum verge and cavum velum interpositum cyst. The whole exome sequencing test showed that the proband carried a missense mutation c.1258 G>A, (p.E420K) in the PPP2R5D gene, and the mutation was de novo confirmed by Sanger sequencing. There were ten literatures reported, including a total number of 31 cases. Counting on this case, totally 32 cases were included. Among the 32 patients, 32 cases (100.0%) had mental retardation, 26 cases (81.3%) with motor retardation, 26 cases (81.3%) with macrocephaly, 8 cases (25.0%) with epilepsy. Facial dysmorphic features, ocular abnormalities, skeletal abnormalities, and cardiac malformations were also reported. All reported individuals had missense mutations of PPP2R5D gene and were autosomal dominantly inherited. Conclusions:The main clinical manifestations of MRD35 include growth retardation/mental retardation, severe speech impairment, macrocephaly, hypomyotonia, seizures and dysmorphic facial features. A novel missense mutation in the PPP2R5D gene is the cause of MRD35.

ABSTRACT

Parthenogenetic embryos, created by activation and diploidization of oocytes, arrest at mid-gestation for defective paternal imprints, which impair placental development. Also, viable offspring has not been obtained without genetic manipulation from parthenogenetic embryonic stem cells (pESCs) derived from parthenogenetic embryos, presumably attributable to their aberrant imprinting. We show that an unlimited number of oocytes can be derived from pESCs and produce healthy offspring. Moreover, normal expression of imprinted genes is found in the germ cells and the mice. pESCs exhibited imprinting consistent with exclusively maternal lineage, and higher X-chromosome activation compared to female ESCs derived from the same mouse genetic background. pESCs differentiated into primordial germ cell-like cells (PGCLCs) and formed oocytes following in vivo transplantation into kidney capsule that produced fertile pups and reconstituted ovarian endocrine function. The transcriptome and methylation of imprinted and X-linked genes in pESC-PGCLCs closely resembled those of in vivo produced PGCs, consistent with efficient reprogramming of methylation and genomic imprinting. These results demonstrate that amplification of germ cells through parthenogenesis faithfully maintains maternal imprinting, offering a promising route for deriving functional oocytes and having potential in rebuilding ovarian endocrine function.

ABSTRACT

Owing to its insidious onset, the diagnosis of ovarian cancer is usually delayed and followed with ascites, which results in a poor prognosis compared to other gynecological malignant tumors. Ascites, a pathological accumulation of fluid in the abdominal cavity, contains a variety of cellular and non-cellular components, which promotes tumor metastasis, leads to chemotherapy resistance, and seriously affects the quality of life and prognosis of patients. In this article, the basic characteristics and the recent progress of ascites in ovarian cancer are reviewed, so as to provide references for further research.

ABSTRACT

Objective:To investigate the effect of inspiratory muscle training on the lung function and diaphragm movement of stroke survivors.Methods:Twenty-four stroke survivors were randomly divided into a control group and an experimental group. Both groups were given routine rehabilitation therapy, while the experimental group was additionally provided with 20 minutes of inspiratory muscle training, 5 times per week for 4 weeks. Before and after the treatment, the forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF) expressed as percentages of the predicted values were used to assess ventilation. The maximum inspiratory pressure (MIP) and peak inspiratory flow (PIF) were used to assess inspiratory muscle function. Diaphragm mobility, as well as the diaphragm′s thickness at the end of expiration (DTee) and inspiration (DTei) and the diaphragm thickening fraction (DTF) were measured using ultrasonography. Any pulmonary infection was also recorded.Results:There was no significant difference between the two groups in any of the measurements before treatment. After the intervention the average FVC, FEV1, MIP, PIF, diaphragm mobility, DTei and DTF of the experimental group were all significantly better than before treatment and significantly better than the control group′s averages. However, no significant difference was found in the average PEF or DTee, nor in the rate of pulmonary infection between the two groups.Conclusion:Inspiratory muscle training can effectively improve ventilation, inspiratory muscle function, diaphragm mobility and diaphragm thickness at the end of inspiration among stroke survivors.

ABSTRACT

Objective To evaluate the role of mitochondrial ATP sensitive potassium ( mito-KATP ) channel in dexmedetomidine-induced inhibition of subarachnoid hemorrhage ( SAH )-caused programmed cell death ( PCD) in cardiomyocytes of rats. Methods On hundred and twenty clean-grade healthy male Sprague-Dawley rats, aged 9-10 weeks, weighing 350-400 g, were divided into 5 groups ( n=24 each) using a random number table method: sham operation group ( group Sham ) , SAH group, SAH plus dexmedetomidine group ( group SD) , 5-HD plus SAH and dexmedetomidine group ( group HSD) and 5-HD plus SAH group ( group HS) . The rats were subjected to SAH by intracranial vascular puncture after being anesthetized with pentobarbital sodium. Dexmedetomidine 5 μg∕kg was infused for 10 min via the jugular vein starting from the time point after intracranial vascular puncture, followed by a continuous infusion of 5μg·kg-1 ·h-1 for 1 h in SD and HSD groups. 5-HD 30 mg∕kg was intraperitoneally injected at 1 h before intracranial vascular puncture in HSD and HS groups. Blood samples were collected from the abdominal aor-ta at 24 h after intracranial vascular puncture for determination of serum cardiac troponin I ( cTnI) concen-trations. The animals were then sacrificed, and myocardial specimens were collected for determination of PCD rate ( by TUNEL) , reactive oxygen species ( ROS) activity ( by DCFH-DA assay) , and expression of cleaved caspase-3, cleaved caspase-1 and interleukin-1beta ( IL-1β) ( by Western blot) . Results Com-pared with group Sham, the serum concentrations of cTnI, PCD rate and ROS activity were significantly in-creased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in SAH, SD, HSD and HS groups ( P<0. 05) . Compared with group SAH, the serum concentrations of cTnI, PCD rate and ROS activity were significantly decreased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas down-regulated in group SD, and the serum concentrations of cTnI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in group HS ( P<0. 05) . Compared with group SD, the serum concentrations of cT-nI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1β was up-regulated in group HSD ( P<0. 05) . Compared with group HSD, the serum concentrations of cTnI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in group HS ( P<0. 05) . Conclusion mito-KATP channel is involved in dexmedetomidine-induced inhibition of PCD in cardiomyocytes of rats with SAH.

ABSTRACT

With the innovation of radiotherapy equipment and the promotion of targeted therapy and immunotherapy,the therapeutic mode and status of radiotherapy in non-small cell lung cancer(NSCLC)are constantly changing. For early NSCLC,stereotactic radiotherapy may be an alternative to surgery,but the optimal segmentation model still needs to be explored. As for locally advanced NSCLC,postoperative radio-therapy is still controversial for operable patients,the results of consolidated immunotherapy after concurrent chemoradiotherapy in inoperable patients are encouraging,prophylactic cranial irradiation does not improve sur-vival. Local radiotherapy for patients with oligometastasis is expected to prolong survival.

Objective To evaluate the efficacy of microsurgical techniques combined with bone transportation for osteomyelitis following open fracture on the leg.Methods From April 2007 to April 2016,25 patients with osteomyelitis caused by severe open injury on the leg were treated at Orthopaedic Department,General Hospital of Rocket Force.They were 22 men and 3 women,aged from 19 to 65 years (average,36.5 years).Their open injury was located at upper tibia in 6 cases,at middle tibia in 6 and at lower tibia in 13.Eight patients received internal fixation with plate and 17 unilateral external fixation.By the Cierny-Mader classification,their chronic osteomyelitis was of type Ⅲ in 14 cases and of type Ⅳ in 11.The tibial defects after excision of infectious segment ranged fromn 5 to 14 cm in length (average,8.8 cm).After infectious tissues were removed,antibiotic bone cement chains were inserted into the defects.The open wounds were covered with microsurgical pedicled or free flaps.Bone transportation with unilateral external fixation was used to deal with the bone defects after removal of the infectious bone.Results Bone infection was controlled in the 25 patients.The rate of infection control after one debridement procedure was 76.0% (19/25),and that after 2 debridement procedures was 24.0% (6/25).Flap repair led to early closure of the open wounds.The successful rate of wound closure after one operative procedure was 84.0% (21/25),and that after secondary operation was 16.0% (6/25).Bony union of tibial defects was achieved in all the 25 patients with no recurrence of osteomyelitis.The patients were followed up for 18 to 36 months (average,24.6 months).Re-fracture happened in one case and was treated with another operation.Bone union time starting from bone transportation ranged from 8 to 18 months (average,10.5 months).Time for external fixation ranged from 12 to 20 months (average,18.4 months).Conclusion For osteomyelitis caused by severe open injury on the leg,microsurgical techniques can be used to repair open wounds and bone transportation to reconstruct bone defects after removal of infectious bone.
