Abstract
Objective: To investigate the clinical features and genetic features of combined oxidative phosphorylation deficiency 32 (COXPD32) caused by MRPS34 gene variation. Methods: The clinical data and genetic test of a child with COXPD32 hospitalized in the Department of Neurology, Children's Hospital, Capital Institute of Pediatrics in March 2021 were extracted and analyzed. A literature search was implemented using Wanfang, China biology medicine disc, China national knowledge infrastructure, ClinVar, human gene mutation database (HGMD) and Pubmed databases with the key words "MRPS34" "MRPS34 gene" and "combined oxidative phosphorylation deficiency 32" (up to February 2023). Clinical and genetic features of COXPD32 were summarized. Results: A boy aged 1 year and 9 months was admitted due to developmental delay. He showed mental and motor retardation, and was below the 3rd percentile for height, weight, and head circumference of children of the same age and gender. He had poor eye contact, esotropia, flat nasal bridge, limbs hypotonia, holding instability and tremors. In addition, Grade Ⅲ/6 systolic murmur were heard at left sternal border. Arterial blood gases suggested that severe metabolic acidosis with lactic acidosis. Brain magnetic resonance imaging (MRI) showed multiple symmetrical abnormal signals in the bilateral thalamus, midbrain, pons and medulla oblongata. Echocardiography showed atrial septal defect. Genetic testing identified the patient as a compound heterozygous variation of MRPS34 gene, c.580C>T (p.Gln194Ter) and c.94C>T (p.Gln32Ter), with c.580C>T being the first report and a diagnosis of COXPD32. His parents carried a heterozygous variant, respectively. The child improved after treatment with energy support, acidosis correction, and "cocktail" therapy (vitaminB1, vitaminB2, vitaminB6, vitaminC and coenzyme Q10). A total of 8 cases with COXPD32 were collected through 2 English literature reviews and this study. Among the 8 patients, 7 cases had onset during infancy and 1 was unknown, all had developmental delay or regression, 7 cases had feeding difficulty or dysphagia, followed by dystonia, lactic acidosis, ocular symptoms, microcephaly, constipation and dysmorphic facies(mild coarsening of facial features, small forehead, anterior hairline extending onto forehead,high and narrow palate, thick gums, short columella, and synophrys), 2 cases died of respiratory and circulatory failure, and 6 were still alive at the time of reporting, with an age range of 2 to 34 years. Blood and (or) cerebrospinal fluid lactate were elevated in all 8 patients. MRI in 7 cases manifested symmetrical abnormal signals in the brainstem, thalamus, and (or) basal ganglia. Urine organic acid test were all normal but 1 patient had alanine elevation. Five patients underwent respiratory chain enzyme activity testing, and all had varying degrees of enzyme activity reduction. Six variants were identified, 6 patients were homozygous variants, with c.322-10G>A was present in 4 patients from 2 families and 2 compound heterozygous variants. Conclusions: The clinical phenotype of COXPD32 is highly heterogenous and the severity of the disease varies from development delay, feeding difficulty, dystonia, high lactic acid, ocular symptoms and reduced mitochondrial respiratory chain enzyme activity in mild cases, which may survive into adulthood, to rapid death due to respiratory and circulatory failure in severe cases. COXPD32 needs to be considered in cases of unexplained acidosis, hyperlactatemia, feeding difficulties, development delay or regression, ocular symptoms, respiratory and circulatory failure, and symmetrical abnormal signals in the brainstem, thalamus, and (or) basal ganglia, and genetic testing can clarify the diagnosis.

Abstract
Objective: To analyze the clinical characteristics and treatment of middle ear myoclonus. Methods: Fifty-six cases of middle ear myoclonus were enrolled in Shandong Provincial ENT Hospital, Shandong University from September 2019 to August 2021, including 23 males and 33 females. The age ranged from 6 to 75 years, with a median age of 35 years; Forty-seven cases were unilateral tinnitus, nine cases were bilateral tinnitus. The time of tinnitus ranged from 20 days to 8 years. The voice characteristics, inducing factors, nature (frequency) of tinnitus, tympanic membrane conditions during tinnitus, audiological related tests, including long-term acoustic tympanogram, stapedius acoustic reflex, pure tone auditory threshold, short increment sensitivity test, alternate binaural loudness balance test, loudness discomfort threshold, vestibular function examination, facial electromyography, and imaging examination were recorded. Oral carbamazepine and/or surgical treatment were used. The patients were followed up for 6-24 months and the tinnitus changes were observed. Results: Tinnitus was diverse, including stepping on snow liking sound, rhythmic drumming, white noise, and so on. The inducing factors included external sound, body position change, touching the skin around the face and ears, speaking, chewing and blinking, etc. Forty-four cases were induced by single factor and 9 cases were induced by two or more factors. There was no definite inducing factor in 1 case. One patient had tinnitus with epilepsy. One case of traumatic facial paralysis after facial nerve decompression could induce tinnitus on the affected side when the auricle moved. Tympanic membrane flutter with the same frequency as tinnitus was found in 12 cases by otoscopy, and the waveform with the same frequency as tinnitus was found by long-term tympanogram examination. There were 7 patients with no tympanic membrane activity by otoscopy, the 7 cases also with the same frequency of tinnitus by long-term tympanogram examination, but the change rate of the waveform was faster than that of the patients with tympanic membrane flutter. All patients with tinnitus had no change in hearing. One case of tinnitus complicated with epilepsy (a 6-year-old child) was treated with antiepileptic drug (topiramate) and tinnitus subsided. One case suffered from tinnitus after facial nerve decompression for traumatic facial paralysis was not given special treatment. Fifty-four cases were treated with oral drug (carbamazepine), of which 10 cases were completely controlled and 23 cases were relieved; 21 cases were invalid. Among the 21 patients with no effect of carbamazepine treatment, 8 patients were treated by surgery, 7 patients had no tinnitus after surgery, 1 patient received three times of operation, and the third operation was followed up for 6 months, no tinnitus occurred again. The other 13 cases refused the surgical treatment due to personal reasons. Conclusions: Middle ear myoclonus tinnitus and the inducing factors manifestate diversity. Oral carbamazepine and other sedative drugs are effective for some patients, and surgical treatment is feasible for those who are ineffective for medication.

Abstract
Objective: To investigate the efficacy of anterolateral thigh flap preforming tongue in patients with total glossectomy. Methods: A total of 27 patients with tongue cancer who underwent total glossectomy, neck lymph node dissection and anterolateral thigh flap transfer were collected from January 2019 to April 2021 in the Department of Oral and Maxillofacial Surgery at the Second Xiangya Hospital. All patients were males, the age ranged from 35-73 years. The patients were divided into experimental (14 cases) and control (13 cases) groups, based on whether the tongue was reconstructed. The clinical parameters of two groups were analyzed by independent sample t test or Fisher exact probability method. Results: The success rate of free flap was 100%, of the patients, 2 patients had cervical hematoma and 1 patient had wound infection postoperatively. There was no difference in speech (6.69±3.42 vs. 5.50±3.01, t=0.96, P=0.346) or swallowing (χ2=0.46, P=0.793) function between two groups at 1 month after surgery. However, the speech (24.94±7.43 vs. 18.44±6.30, t=2.48, P=0.020) and swallowing (χ2=6.97, P=0.008) functions in experimental group were significantly better than those in control group. No case was lost to follow-up. All patients were extubated after operation, with average time of 7.2 days in the experimental group and 7.7 days in the control group. The overall survival rate was 71.4% in the experimental group and 61.5% in the control group. Conclusion: The use of anterolateral thigh flap preforming tongue can improve the speech and swallowing functions in patients with total glossectomy and offer a novel method for tongue construction.

Abstract
Objective: To investigate the effect of continuous intravenous infusion of subanesthetic dose of esketamine intraoperatively on postoperative opioid consumption in patients undergoing thoracoscopic surgery. Methods: A total of 71 patients with elective thoracoscopic lung surgery in the First Affiliated Hospital of Zhengzhou University from December 2020 to December 2021 were selected. Patients who were classified as grade Ⅰ or Ⅱ by the American Society of Anesthesiologists (ASA) and aged 18-70 years were included, including 32 males and 39 females, with a body mass index (BMI) of 18.5-30.0 kg/m2. The patients were randomly divided into three groups: (1) Control group (group C, n=24): continuous intravenous infusion of normal saline at the same rate during surgery; (2) Subanesthetic dose of esketamine 0.125 mg·kg-1·h-1 group (group ES1, n=23): continuous intravenous infusion of esketamine at a rate of 0.125 mg·kg-1·h-1 during surgery; (3) Subanesthetic dose of esketamine 0.250 mg·kg-1·h-1 group (group ES2, n=24): continuous intravenous infusion of esketamine at a rate of 0.250 mg·kg-1·h-1 during surgery. The main outcome measures were the total consumptions of hydromorphone of 3 groups within 24 and 48 hours after surgery. The secondary outcome measures were the extubation time, length of postanesthesia care unit (PACU) stay, the time of first feeding, and the incidences of adverse effects within 24 h after surgery in 3 groups. Results: The 24 h postoperative consumption of hydromorphone in group C, ES1 and ES2 was (5.4±1.0) mg, (4.5±1.5) mg and (4.0±0.8) mg, respectively. Likewise, the 48 h postoperative consumption of hydromorphone was (9.7±2.2) mg, (9.0±3.0) mg and (7.7±1.8) mg, respectively. Compared with group C, the 24 h postoperative hydromorphone consumptions were significantly reduced in group ES1 and ES2 (both P<0.05). The extubation time, length of PACU stay and the time of first feeding after surgery in group C were (23±10) min,(70±12) min,(17±3) h,in group ES1 were (22±4) min,(69±11) min,(14±5) h,in group ES2 were (16±8) min,(58±12) min,(14±3) h, respectively. Compared with group C and group ES1, both of the extubation time and length of PACU stay were shortened in group ES2 (both P<0.05). Compared with group C, the first postoperative feeding time of group ES1 and ES2 was shortened (both P<0.05). There were no differences in the incidences of adverse effects at postoperative 24 h among 3 groups (all P>0.05). Conclusion: Continuously intravenous infusion of subanesthetic esketamine at a rate of 0.250 mg·kg-1·h-1 can significantly reduce the postoperative opioid consumption and improve the patient's outcomes.

Abstract
A pedigree genetic analysis of a female Duchenne muscular dystrophy (DMD) inherited from paternal chimerism was conducted to explore the genetic diagnosis strategy. No large deletions/duplications was found in the DMD gene of the proband. Next-generation sequencing (NGS) results showed that the proband had a heterozygous mutation in the DMD gene c.4707C>A (p.C1569X). This locus has not been reported in the literature and is considered as a pathogenic mutation. Sanger sequencing revealed that the father of the proband carried the same mutation, and the mosaic ratio was about 17.7%. The specific enzyme digestion test showed that the proband had maternal skewed X-inactivation. DMD a recessive inherited disease of the X chromosome, exists in female patients, and very few of them are inherited from paternal origin. Female patients need to pay close attention to skewed X-inactivation and suspected new mutations. Mosaic is not excluded, especially the inheritance of paternal mosaicism with normal phenotype. Prenatal gene screening is necessary for reproduction.

Abstract
Objective: To explore the association between statins and colorectal cancer and provide evidence for the prevention of colorectal cancer. Methods: Literatures about statins and colorectal cancer published from January 2000 to January 2020 were retrieved from CNKI, Wanfang data, PubMed and Cochrane Library database. The literatures which met the inclusion criteria were collected, and the Newcastle-Ottawa Scale and Jadad score were used to assess the studies. Meta-analysis was performed with statistical software Revman 5.0 and Stata 12.1. Results: A total of 31 studies, involving more than 1.62 million subjects, were included in the analysis. The case-control study (RR=0.93, 95%CI: 0.88-0.98), the cohort study (RR=0.75, 95%CI: 0.63-0.88) and the randomized controlled trial (RR=0.79, 95%CI: 0.65-0.97) showed moderate protective effect of statins. Using statin <5 years (RR=0.86, 95%CI: 0.76-0.96), average daily dosage ≥34 mg (RR=0.81, 95%CI: 0.66-0.98) and lipid-soluble statins (RR=0.86, 95%CI: 0.74-0.99) also had preventive effect on colorectal cancer; while lovastatin (RR=1.07, 95%CI: 1.00-1.14) increased the risk of colorectal cancer. Conclusion: Statins have protective effect on colorectal cancer.

Abstract
We perform a comprehensive study of Milky Way (MW) satellite galaxies to constrain the fundamental properties of dark matter (DM). This analysis fully incorporates inhomogeneities in the spatial distribution and detectability of MW satellites and marginalizes over uncertainties in the mapping between galaxies and DM halos, the properties of the MW system, and the disruption of subhalos by the MW disk. Our results are consistent with the cold, collisionless DM paradigm and yield the strongest cosmological constraints to date on particle models of warm, interacting, and fuzzy dark matter. At 95% confidence, we report limits on (i) the mass of thermal relic warm DM, m_{WDM}>6.5 keV (free-streaming length, λ_{fs}≲10h^{-1} kpc), (ii) the velocity-independent DM-proton scattering cross section, σ_{0}<8.8×10^{-29} cm^{2} for a 100 MeV DM particle mass [DM-proton coupling, c_{p}≲(0.3 GeV)^{-2}], and (iii) the mass of fuzzy DM, m_{ϕ}>2.9×10^{-21} eV (de Broglie wavelength, λ_{dB}≲0.5 kpc). These constraints are complementary to other observational and laboratory constraints on DM properties.

Abstract
Objective: To investigate the clinical and genetic characteristics of developmental and epileptic encephalopathy (DEE) caused by syntaxin-binding protein 1 (STXBP1) gene mutation. Methods: The clinical data, gene variation and treatment outcome of 15 children with STXBP1 encephalopathy admitted to Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2014 to June 2019 were analyzed retrospectively. Results: Among 15 patients, 11 were male and 4 were female, age ranged from 2 months to 69 months. The clinical manifestations of 14 children were epilepsy and developmental delay (DD) and the remaining one showed developmental delay without seizure. The onset age of epilepsy ranged from two days to 19 months and 11 of them experienced the first attack before 1 year of age. The common seizure types were epileptic spasms and tonic seizures. Seven patients were diagnosed with Ohtahara syndrome or West syndrome. Epileptic form discharges were observed in the interictal electroencephalograms (EEG) of 11 patients, including multifocal discharges, suppression-burst and hypsarrhythmia. The brain magnetic resonance imaging of 7 children were abnormal, including myelin dysplasia, less white matter, lack of corpus callosum or hypoplasia. The follow-up time ranged from 2 months to 57 months, after the last follow-up, 3 cases were seizure free, 6 children showed partial response and the other 5 patients had no response on multitherapy. Six of 8 patients showed good responses to levetiracetam (LEV) monotherapy or in combination with other antiepileptic drugs (AEDs). Vigabatrin (VGB) was applied to 5 patients with epileptic spasms and 4 of them showed response. All patients showed different degrees of developmental delay while four of them showed autistic features. STXBP1 gene mutations were identified in all cases and there were 15 types of gene variations, including 8 missense mutations, 1 nonsense mutation, 5 frame shift mutations and 1 complex mutation. Five novel mutations were unreported before, including c.1193A>G, c.172delG, c.1769C>T, c.1038_1039delCC, c.348_351dupTGAA. Conclusions: Development delay and epilepsy are the major and independent clinical phenotypes in children with STXBP1 encephalopathy. The variation of STXBP1 gene is mainly de novo. Levetiracetam and vigabatrin may be more effective in epilepsy control than other AEDs.

Abstract
Objective To explore polygraph accuracy of Control Question Test (CQT)and whether it could be influenced by examinee's education level and type of violation of law. Methods Real cases of CQT (n=104) and the data from MAO (n=296) were collected. The polygraph accuracy of CQT was calculated. Variance analysis on three groups of different education levels was used to compare their age, and then the chi-square test was employed to compare polygraph accuracy among the groups. Independent sample t test was used to compare the age of subjects in the two groups of different types of violation of law, and then chi-square test was used to compare the true positive rate and true negative rate of lie detection after integration. Results In CQT lie detection of criminal cases, the true positive rate was 87.00%, the false negative rate was 13.00%, the true negative rate was 82.20%, and the false positive rate was 17.80%. There was no statistical significance in the differences between the true positive rate and the true negative rate (P>0.05). In CQT lie detection of the groups of different education levels, there was no statistical significance in the differences between the true positive rates (P>0.05) while the differences between the true negative rates had statistical significance (P<0.05). There was no statistical significance in the differences of both the true positive rates and the true negative rates between the violent violation of law and non-violent violation of law (P>0.05). Conclusion There is no significant difference between the efficiency of CQT lie detection of identifying criminals and excluding innocents. However, a comparatively high false positive rate and false negative rate still exist. The efficiency of CQT lie detection identifying criminals may not influenced by the examinee's education level and type of violation of law, but its efficiency of excluding innocents may be influenced by the examinee's education level.

Abstract
Objective: To analyze the de novo point mutations in known genes among patients with unexplained intellectual disability (ID) or developmental retardation (DD). Methods: A total of 120 outpatients with ID or DD were recruited in the Department of Neurology, Affiliated Children's Hospital of Capital Institute of Pediatrics between September 2015 and April 2017. Target gene sequencing was used to screen the candidate gene. The sequencing data were analyzed by a variety of bioinformatics software. Combining with the phenotypes of the patients, the candidate genetic/genomic variants were identified from next-generation sequencing data. The final pathogenicity of the genetic/genomic variants were interpreted according to the guideline of the American College of Medical Genetics and Genomics (ACMG) for variants after segregation analysis in the parents and necessary family members by Sanger sequencing. The comprehensive physiological function and signaling pathways of 20 disease genes with de novo point mutation discovery was also studied. Results: Among the 120 patients, 23 patients were found to carry clear pathological changes, and the incidence of de novo point variation was 19.2%. The patients included 12 males and 11 females, with an age of 2 months to 6-year-6-month. Five patients were diagnosed with early onset of epileptic encephalopathy. Seven had mental retardation type 5, 6, 8, 19, 20, 22, 39, respectively. Weill-Marchesani syndrome type 2 was found in one case, Wiedemann-Steiner syndrome in one case, Coffin-Siris syndrome in two cases, Rubinstein-Taybi syndrome in one case, GLUT1 deficiency syndrome in one case, Rett syndrome in one case, cardio-facio-cutaneous syndrome 3 in one case, neurodegeneration with brain iron accumulation in one case, corpus callosum local dysplasia in one case, and congenital fibrosis of the extra-ocular muscles in one case. A total of 20 novel mutations were reported in this study. No somatic mutation was found in the samples of 6 patients with mutation and their parents' peripheral blood DNA samples by amplicon-based deep sequencing. This study found that the main disease genes were involved in chromatin remodeling, transcriptional regulation, autophagy body assembly, MAPK signal pathway, DNA methylation, potassium, sodium ion transport, cell skeleton assembly and skeletal muscle development. These genes were significantly enriched in the following biological processes: Ras signaling pathways, transcription factor binding and cancer related signaling pathway. Conclusions: The etiology of children affected with intellectual disability or developmental delay is complex. Harmful de novo point mutation plays an important role in these diseases. Targeted exome/genome sequencing based on the core family is helpful for the molecular diagnosis of patients and the discovery of more genes.

Abstract
Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Abstract
BACKGROUND The role of cytomegalovirus (CMV) infection in renal allograft rejection remains controversial; moreover, there are few studies on pretransplant infections. This study sought to investigate whether pretransplant CMV infections had negative effects on acute rejection episodes (ARE) and to evaluate the effect of preemptive treatment. METHODS This retrospective single-center study of 416 transplant recipients from October 1, 2000 to September 1, 2003 had CMV infections diagnosed by CMV antigenemia tests. The incidences of ARE were compared between CMV-infected and noninfected groups. Risk factors for ARE were analyzed. Based on preemptive treatment, pretransplant CMV-infected recipients were divided into ganciclovir-treated and nontreated groups and the incidence of ARE was compared between the two groups. RESULTS One hundred eighty four recipients had CMV infections pretransplant; the infection rate was 44.2%. Fifty five recipients had ARE among the pretransplant CMV-positive group, which was significantly higher than that in the noninfected group (29.9% vs 19.5%, P = .014). But the rejection subgroups and renal function recovery had no significant differences. While the presence of pretransplant infection was an independent predictor of ARE (RR = 1.807), severity showed no significant impact on ARE. Among 184 pretransplant CMV infection recipients, the incidences of ARE were 14.3% and 18.0% in ganciclovir-treated versus nontreated patients, respectively (P = .650). CONCLUSIONS Pretransplant CMV-positive recipients were at greater risk of ARE. Pretransplant CMV infection was an independent risk factor for ARE. Preemptive antiviral treatment did not show protective effects against ARE related to CMV infection-mediated immunological injuries.

Abstract
The inhibitory effects of six flavonoids from Hypericum perforatum were assessed spectrophotometrically using nitric oxide synthase (NOS) in blood and cerebral homogenate of rats. Of the assayed compounds, quercetin and hyperoside showed concentration-dependent enzyme inhibitory actions. The IC50 values of quercetin for inhibiting NOS in rat cerebral homogenate and blood were 63.06 and 57.54 microM, and those of hyperoside 56.23 and 158.49 microM, respectively. The competitive patterns were discerned with the inhibition of the two flavonoids on NOS in serum and cerebral homogenate (except a mixed type inhibition was observed with quercetin in inhibiting cerebral NOS). Furthermore, similar inhibitions were found for quercetin upon NOS in cerebral homogenate and blood. However, a stronger inhibitory effect of hyperoside on the enzyme was discerned in cerebrum than in blood. These results suggested that the galactose moiety in hyperoside may be associated with the selectivity of the NOS inhibition.
