Abstract
Background Coffin-Siris syndrome (CSS) is a rare autosomal dominant disorder characterized by intellectual disability, developmental delay, and characteristic facial features. Few patients with cutaneous phenotype in this rare syndrome have been reported. Case presentation Herein, we describe a 12-year-old Chinese girl diagnosed with CSS, who was referred to our hospital because of intellectual disability and short stature. Prominent characteristics of the cutaneous system were observed: (1) A congenital giant nevus from the left frontal and temporal regions to the entire left scalp; and (2) multiple melanocytic nevi on the face and trunk. Whole exome sequencing revealed a novel heterozygous variant in the ARID1B gene. Recombinant human growth hormone (rhGH) was given for short stature, and resulted in significantly improved height. No enlargement or malignant transformation of nevi occurred within 4 years of follow-up. Conclusion The symptoms in cutaneous system is noteworthy,which may be a neglected phenotype in CSS.The therapeutic response of growth hormone is effective in this patient and no tumor related signs were found. Supplementary Information The online version contains supplementary material available at 10.1186/s12887-022-03535-4.

Abstract
BACKGROUND Pyruvate carboxylase deficiency (PCD; MIM#266150) is a rare autosomal recessive disorder characterized by a wide range of clinical features, including delayed neurodevelopment, elevated pyruvate levels, lactic acidosis, elevated ketone levels, and hyperammonemia. The pyruvate carboxylase (PC) gene was identified to be the disease-causing gene for PCD. A novel homozygous splice variant in the PC gene was identified in a Chinese boy, but the pathogenicity is still unclear. The objective of the present study was to determine the effect of this splice-site variant by reverse transcription analysis. METHODS We reported the clinical course of a 20-month-old Chinese pediatric patient who was diagnosed with PCD using whole-exome sequencing (WES). The effects of the variant on mRNA splicing were analyzed through the transcript analysis in vivo. RESULTS The results of metabolic blood and urine screening suggested PCD by employing tandem mass spectrometry. WES revealed a novel homozygous splice-site variant (c.1825+5G>A) in the PC gene. in vivo transcript analysis indicated that the splice-site variant caused the retention of 192 bp of the intron. CONCLUSION Thus, c.1825+5G>A was established as a pathogenic variant, thereby enriching the mutational spectrum of the PC gene and providing a basis for the genetic diagnosis of PCD.

Abstract
OBJECTIVE To investigate the effects of recombinant human growth hormone (rhGH) on the morphology and function of the left cardiac ventricle in young rats with dilated cardiomyopathy (DCM), and to evaluate the efficacy and safety of rhGH in the treatment of DCM. METHODS Sixty male Sprague-Dawley rats were randomly and equally assigned to control group, DCM group, and rhGH group. Furazolidone (0.25 mg/g) was given by gavage for 12 weeks to prepare the DCM model. Rats in the rhGH group received an intraperitoneal injection of rhGH (0.15 U/kg) once per day for 12 weeks, while rats in the DCM group received an equal volume of normal saline instead. Rats in the control group did not receive any treatment. Cardiac indices, serum biochemical parameters, hemodynamic indices, cardiac histopathological changes, and levels of myocardial collagen fibrils in each group were determined using Doppler echocardiography, enzyme-linked immunosorbent assay, multi-channel physiological recorder, light and electron microscopy, and picrosirius red staining plus polarization microscopy, respectively. RESULTS Compared with the control group, rats in the DCM group had significantly increased cardiac chamber size, significantly reduced ventricular wall thickness, and significantly decreased fractional shortening (FS) and ejection fraction (EF) (P<0.05). Rats in the rhGH group had significantly improved cardiac chamber size, ventricular wall thickness, FS, and EF compared with the DCM group (P<0.05). Those indices in the rhGH group were similar to those in the control group (P>0.05). There were significant differences in serum biochemical parameters and hemodynamic indices between the DCM and control groups (P<0.05). Compared with the DCM group, the rhGH group had significantly improved serum biochemical parameters and hemodynamic indices (P<0.05). Those indices in the rhGH group were similar to those in the control group (P>0.05), except for the levels of insulin-like growth factor-1 and insulin-like growth factor-binding protein-3. The DCM group had a significantly higher collagen type I/collagen type III (Col I/Col III) ratio in the myocardium than the control group (P<0.05), and there was no significant difference in the Col I/Col III ratio between the control and rhGH groups (P>0.05). CONCLUSIONS rhGH plays a certain role in improvement in the morphology and function of the left cardiac ventricle in young rats with DCM.

Abstract
OBJECTIVE To investigate the clinical and pathological features of progressive muscular dystrophy (PMD) in children and to provide help for the early and accurate diagnosis of PMD. METHODS Retrospective analysis was performed on the clinical data of 99 hospitalized children with PMD, including clinical manifestations, age of onset, family history, creatase, electromyogram (EMG) and pathological changes of muscles. RESULTS Of the 99 children with PMD, the age of onset was 0.5-14.5 (4.7 ± 3.1) years. Eleven cases (11%) had a family history of PMD. Twenty-six (26%) were misdiagnosed as other diseases. All patients presented with muscle weakness when seeing the doctor, and 66 (67%) of them had muscle atrophy and/or hypertrophy. All patients had elevated creatine kinase (CK) levels. The 2-7-year-old group (n=51) had a mean CK level of 9965 ± 8876 U/L, and the 7-15-year-old group (n=48) had a mean CK level of 5110 ± 4498 U/L, with a significant difference between the two groups (P<0.01). The EMG examination performed on 66 patients showed that 54 cases (82%) had myogenic damage and 10 cases (15%) had neurogenic damage. Light microscopy revealed coexistence of atrophy and hypertrophy of muscle fibers, hyaline degeneration and granular degeneration. Electron microscopy showed that muscle fibers were different in thickness, some atrophic or hypertrophic; muscle cell nuclei moved inwardly, myofilaments dissolved and disappeared mildly under the sarcolemma, there were scattered melting lesions within muscle fibers, the numbers of glycogen granules and mitochondria increased, mild hyperplasia and expansion of sarcoplasmic reticulum were seen, and a small number of muscle fibers had necrosis. CONCLUSIONS Weakness of both lower extremities remains the main reason for PMD patients seeing the doctor. CK is the main laboratory indicator for diagnosis of PMD. PMD is mainly manifested as myogenic damage in the early stage and may be accompanied by neurogenic damage in the late stage, according to the EMG examination. With a high misdiagnosis rate, PMD may be misdiagnosed as many other diseases. Pathological examination under light microscope and electron microscope is the main means for confirming a PMD diagnosis.

Abstract
OBJECTIVE To investigate the main inhalant allergens and their distribution patterns in children with allergic diseases from Xi'an and the surrounding area and to provide evidence for the prevention and treatment of allergic diseases in children. METHODS Skin prick test was performed using liquid with 13 standardized allergens (ALK-ABELL, Denmark) on 3085 children from Xi'an and the surrounding area who were treated for allergic diseases between July 2006 and July 2011, to detect inhalant allergens. RESULTS Of the 3085 patients, 1368 (44.34%) had positive SPT results, with the most prevalent inhalant allergen being Dermatophagoides pteronyssinus (804 cases, 26.06%), followed by Dermatophagoides farinae (793 cases, 25.71%), Blomia tropicalis (440 cases, 14.26%), mugwort (282 cases, 9.14%), and cat hair (204 cases, 6.61%). The positive rates were 28.66% in the <4 years group, 41.85% in the 4-6 years group, and 58.61% in the 7-15 years group (P<0.01). Males had a significantly higher SPT positive rate than females (47.78% vs 38.50%;P<0.05). The SPT positive rate was highest in children with allergic rhinitis (72.41%), followed by bronchial asthma (62-25%), allergic dermatosis (45.83%), and allergic purpura (36.28%). CONCLUSIONS In children from Xi'an and the surrounding area, the main inhalant allergens for allergic diseases include Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis, mugwort and cat hair. The SPT positive rate increases with age. Male children have a higher SPT positive rate than female children. The SPT positive rate is highest in children with allergic rhinitis.

Abstract
OBJECTIVE To study the efficacy of erythropoietinin (EPO) in the treatment of moderate or severe hypoxic-ischemic encephalopathy (HIE) in neonates. METHODS Seventy neonates with moderate or severe HIE were randomly assigned to two groups: EPO treatment and control (n=35 each). The EPO treatment group included 22 cases of moderate HIE and 13 cases of severe HIE. The control group included 24 cases of moderate HIE and 11 cases of severe HIE. Thirty-five healthy full-term infants served as normal group. The control group received a conventional treatment. Beside the conventional treatment, the EPO treatment group was intravenously injected with EPO of 200 IU/kg•d, 3 times weekly. Routine blood test was performed every 6 days. EPO dose was adjusted based on the results of the routine blood test. The course of EPO treatment was 2 to 4 weeks. Neonatal Behavioral Neurological Assessment (NBNA) was performed at age of 28 days. The infant development test of Child Development Centre of China (CDCC) was performed at ages of 3 months and 6 months. RESULTS The percentage of normal NBNA scores in the EPO treatment group was significantly higher than that in the control group at age of 28 days (P<0.05), but was significantly lower than that in the normal group (P<0.01). The CDCC test including physical development index (PDI) and physical development index (MDI) showed the percentage of normal results in the EPO treatment group was significantly higher than in the control group at age of 3 months (P<0.05), but was significantly lower than in the normal group (P<0.01). The CDCC test including PDI and MDI showed that the percentage of normal results in the EPO treatment group was significantly higher than in the control group at age of 6 months. The MDI test results in the EPO treatment group were not significantly different from those in the normal group at age of 6 months, but the percentage of normal results in the PDI test in the EPO treatment group was still significantly lower than that in the normal group (P<0.05). CONCLUSIONS EPO treatment has neuroprotective effects against moderate or severe HIE and improves long-term behavioral neurological developments in neonates.

Abstract
OBJECTIVE Interventional treatment for childhood combined congenital heart disease (CHD) has developed very quickly and more new types of occluders have emerged in recent years. The aim of this study is to investigate the efficiency and safety of interventional treatment for combined CHD in children. METHODS Eight children with combined CHD (4 boys and 4 girls), aged 6.1+/-2.9 years, underwent simultaneous transcatheter therapy. Of the 8 children with CHD, 1 case had atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA), 1 case had ASD, PDA and pulmonary stenosis (PS), 1 case had ASD and PDA, 1 case had patent foramen ovale (PFO) and PS, and 4 cases had ASD and PS. The methods of transcatheter intervention for these patients were as follows: in patients with ASD,VSD and PDA, the occlusion of VSD was performed first, followed by PDA and ASD occlusions; in patients with ASD, PDA and PS, the occlusion of percutaneous balloon pulmonary valvuloplasty (PBPV) was performed first, followed by PDA and ASD occlusions; in patients with PFO and PS, the occlusion of PBPV was performed first, and PFO occlusion followed; in patients with ASD and PS, the occlusion of PBPV was performed first, and ASD occlusion followed. RESULTS The intervention operation was successfully performed in all of the 8 patients. No serious adverse events occurred during the operation. No residual shunt was found and all the occlusion devices were in the suitable sites shown by transthoracic echocardiography (TTE) and X-ray right after the operation. In the 6 patients with PS, the systolic pressure across the pulmonary valve decreased from 75.3+/-15.6 mmHg (before operation) to 14.0+/-5.6 mmHg after operation (P<0.05).A 3.4+/-1.2 years follow-up demonstrated that no residual shunt occurred and gradients across valve or coarctation sites were within the limit of satisfactory results. No complications were observed during the follow-up. CONCLUSIONS Transcatheter interventional therapy for childhood combined CHD can obtain satisfactory results by proper procedures.

Abstract
AIM: To investigate the survivin gene expression in human hepatocellular carcinoma cell line SMMC-7721 and the effects of survivin gene RNA interference (RNAi) on cell apoptosis and biological behaviors of SMMC-7721 cells.
METHODS: Eukaryotic expression vector of survivin gene RNAi and recombinant plasmid pSuppressorNeo-survivin(pSuNeo-SVV), were constructed by ligating into the vector, pSupperssorNeo (pSuNeo) digested with restriction enzymes Xba I and Sal I and the designed double-chain RNAi primers. A cell model of SMMC-7721 after treatment with RNAi was prepared by transfecting SMMC-7721 cells with the lipofectin transfection method. Strept-avidin- biotin-complex (SABC) immunohistochemical staining and RT-PCR were used to detect survivin gene expressions in SMMC-7721 cells. Flow cytometry was used for the cell cycle analysis. Transmission electron microscopy was performed to determine whether RNAi induced cell apoptosis, and the method of measuring the cell growth curve was utilized to study the growth of SMMC-7721 cells before and after treatment with RNAi.
RESULTS: The eukaryotic expression vector of survivin gene RNAi and pSuNeo-SVV, were constructed successfully. The expression level of survivin gene in SMMC-7721 cells was observed. After the treatment of RNAi, the expression of survivin gene in SMMC-7721 cells was almost absent, apoptosis index was increased by 15.6%, and the number of cells was decreased in G2/M phase and the cell growth was inhibited.
CONCLUSION: RNAi can exert a knockdown of survivin gene expression in SMMC-7721 cells, and induce apoptosis and inhibit the growth of carcinoma cells.

Abstract
BACKGROUND & OBJECTIVE apr-1 was cloned by improved polymerase chain reaction (PCR)-based subtractive hybridization from all-trans retinoic acid (ATRA)-induced apoptotic leukemia HL-60 cells in 1999. Preliminary results showed that apr-1 might be an apoptosis-related gene (GenBank ID: NM_014061). This study was to explore the background of apr-1 through gene cloning, bioinformatic analysis, and subcellular locating. METHODS The cDNA encoding Apr-1 was amplified by reverse transcription-PCR (RT-PCR), and sequenced. Open reading frame (ORF) of apr-1 was analyzed with ORF finder software. Chromosome locus was defined by genome blast software. Conserved domains of amino acids were analyzed by protein blast software. Align (Cluster W) software in Vector NTI software package was used to analyze homogeneous genes (or proteins), and to draw the Phylogenetic Tree. Subcellular localization of apr-1 was performed. RESULTS apr-1 was mapped to chromosome Xp11.22 with the ORF locating in 1 exon. Two MAGE conserved domains were found in Apr-1. Apr-1 shared homology with MAGE-A1, MAGE-B1, MAGE-C1, MAGE-D1, and Necdin. Phylogenetic analysis showed that Apr-1 was more closely related to MAGE-D1 and Necdin. Gene products of apr-1 were located in the nuclei of eukaryocytes. CONCLUSIONS apr-1 is a member of MAGE family, and might belong to type II MAGE genes.

Abstract
We have cloned and identified an insertion sequence, IS1485, that was present in several members of the genus Enterococcus. IS1485 exists in varying copy numbers with at least 12 copies in E. durans (ATCC 11576), 3 copies in E. faecium (ATCC 19434), and one copy each in E. faecalis (ATCC 19433) and E. avium (ATCC 14024). It was also detected in clinical strains of E. gallinarum, E. casseliflavus, and E. saccharolyticus. IS1485 is 1366 bp in length, it has imperfect terminal inverted repeats with 25 of the terminal 39 residues matched, and it contains three open reading frames exceeding 50 codons, designated orfA, orfB, and orfC. The largest, orfB, was located 36 bp downstream and in the -1 reading frame relative to orfA; orfC is oriented in the opposite direction and overlaps orfA. The genetic organization of IS1485 resembles that of members of the IS3 family of transposable elements. Sequence homology exists with several members of the IS3 family especially with IS199 from Streptococcus mutans.

Abstract
The influence of the biological medium on high-intensity focused ultrasound (HIFU) therapy for ablating experimental liver cancer was studied. In study 1, the temperature rise in the focal zone in the presence of iodized oil or castor oil was observed in vitro. The results showed that HIFU with iodized oil produced a higher and faster temperature rise than did HIFU with castor oil, whether high-power (500 W/cm2) or relatively low-power (136 W/cm2) conditions were used (P = 0.0008 and P = 0.0004 respectively). With the excised liver samples, the temperature also rose higher and more rapidly after injection of iodized oil into the liver than when castor oil was injected (P = 0.0239), and the target liver tissue revealed more radically and extensive destruction with iodized oil than with castor oil. In study 2, 48 nude mice, bearing primary liver cancer LTNM4 implanted subcutaneously, were randomly divided into four groups. Group I (n = 12) were the controls, group II (n = 12) were injected with iodized oil alone, group III (n = 12) received HIFU treatment, and group IV (n = 12) were exposed to HIFU after iodized oil injection. Significant inhibition of tumor growth was seen in groups III and IV as compared with group I or group II (P < 0.05), the tumor growth inhibition rate on the 28th day after treatment being 87% and 93% respectively. Significantly improved survival was noted in groups III and IV compared with groups I and II (P < 0.05). Histologically, group IV showed more complete tumor necrosis than did group III. These data suggest that HIFU combined with iodized oil might have achieve of synergism, location and targeting in the treatment of liver cancer.

Abstract
This project aimed to determine the adequacy and accuracy of high-intensity focused ultrasound (HIFU) for ablating experimental liver tumour, and to assess imaging methods for monitoring the therapeutic results. The rabbit liver pseudotumour model was established by injection of Freund's complete adjuvant into the liver; the animals then received HIFU therapy via laparotomy at the focal point of the beam (1.1 MHz, 500 W/cm2, 20 s). The rabbits were sacrificed at scheduled times after treatment and liver tumours were examined histologically. Sequential imaging of the liver tumour was performed before and after HIFU treatment. HIFU accurately destroyed the rabbit liver tumour and induced coagulation necrosis 24 h later. Sonographic imaging studies revealed that characteristic changes occurred. A hyperechoic mass turned to a hypoechoic lesion with no Doppler signal, and a high echogenic rim appeared 24 h after HIFU treatment, correlating well with the pathological changes of a sonoablated lesion. These results verify that HIFU has the power to ablate liver tumour quite adequately and accurately, and that sonography is useful for monitoring sonoablated liver tumour.

Abstract
The activity of Ca(2+)-ATPase and calcium content were measured in sarcoplasmic reticulum (SR) and mitochrondria of myocardium from 40 adult female Wistar rats after exposure to 37 degrees C, 39 degrees C, 41 degrees C and 43 degrees C for 40 min respectively in vitro. The 45Ca uptake, intracellular free Ca2+ concentration ([Ca2+]i) and the relatively active calmodulin content were also observed in cultured cardiomyocytes from 120 neonatal Wistar rats under the same condition of heat exposure. The results showed that (1) the activity of Ca(2+)-ATPase of SR and mitochrondria of myocardium decreased after heat exposure, (2) the calcium content of SR and mitochrondria also showed a tendency of decrease with increase of exposure temperature, (3) the 45Ca uptake and mean [Ca2+]i increased, whereas the calmodulin content decreased. It is suggested that disturbances of intracellular calcium homeostasis may be responsible for cardiac functional disorder after heat exposure.

Abstract
Sodium nitroprusside (NP) alone Was given to the 39 cases with acute high-altitude pulmonary edema (AHPE). 33 of them (84.6%) fully recovered and 6 (15.38%) obviously improved in 72 hours. The total efficacy was 100%. There was obvious improvement in the cardiac pumping and contractile function as well as total peripheral resistance. The mean pulmonary artery pressure (MPAP) decreased from 52.22 +/- 7.51mmHg to 25.13 +/- 10.36mmHg in 3 to 5 hours after the first dose. Strophanthin K was given to another 11 cases with AHPE, But none fully recovered or obviously improved. During the 72 hours of treatment, 4 improved slightly, 4 showed no therapeutic effect and 3 became worse. The heart rate was reduced obviously and cardiac contractile function strengthened while the cardiac pumping function and total peripheral resistance had no change. Vasodilator therapy is a new method for AHPE treatment and this study shows that the NP is an ideal drug in treating AHPE and that dilation of the small pulmonary arteries by NP may explain its efficacy.
