Objective To investigate the changes of nitric oxide content and inducible nitric oxide synthase (iNOS) activity in rat brain tissues after explosive craniocerebral wound and observe the influence of emodin on these changes. Methods After rats were subjected to electric detonators, emodin (10 mg/kg) was injected intraperitoneally at 10 minutes. Water content of brain tissues was measured by using dry-wet methods. The content of nitric oxide and the activity of iNOS were measured at 2, 4, 12 and 24 hours respectively after wound by means of nitrade reductase and colorimctrie method. Results The content of nitric oxide and the activity of iNOS kept at a high level (P<0.01). The content of nitric oxide and the activity of iNOS in model group were increased significantly and reached peak at 2 hours after wound. While the content of nitric oxide and the activity of iNOS in emodin group were significantly lower than that in model group (P<0.01). Conclusion Emodin plays a role in decreasing water content of brain tissues and inhibiting activity of iNOS and may exert a protective effect on brain injury during pathological course after explosive craniocerebral wound.

Objective: To understand the sedentary behavior level of children and adolescents with intellectual disabilities in Jinan City, and to provide a reference basis for developing health behavior intervention strategies. Methods: By used the method of cluster random sampling,the Children s Leisure Activities Study Survey was used to investigate the sedentary behavior level of 285 children and adolescents with intellectual disabilities aged 6-18 years from 7 special education schools in Jinan City. Results: The sedentary behavior time during the whole week among children and adolescents with intellectual disabilities in Jinan City was 394.46 min/d, including 378.00 min/d on weekdays(Monday to Friday) and 388.80 min/d on weekends (Saturday and Sunday), the difference was statistically significant ( Z =-2.19, P <0.05). 80.4%(229) of children and adolescents with intellectual disabilities had sedentary behavior time of more than 2 h/d. The sedentary behavior time per day during the whole week among children and adolescents with intellectual disabilities was negatively correlated with the amount of time spent in moderate vigorous physical activity among them ( r =-0.16, P <0.05). Conclusion Excessive sedentary behavior has become a growing public health concern among children and adolescents with intellectual disabilities,which warrants targeted healthy behavior intervention.

The novel coronavirus disease 2019 (COVID-19) outbreak occurred in December last year and spread quickly in the world, causing great harm to people. The rapid progression of this epidemic makes scholars in various fields conduct research on the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). So far, the wildly accepted routes are droplets and close contact. Controversially, some researchers believe that other routes include aerosol diffusion, fecal-oral transmission, contacting urine, conjunctival infection, and mother-to-infant transmission may also infect people. In this article, combining the newest research and reports, the authors systematically analyzed the theoretical possibility and real-life probability of the transmission routes of the virus in order to help with the research and clinical judgment of the spread of infectious diseases in the future.

OBJECTIVETo elucidate the usefulness of next generation sequencing for diagnosis of inherited myopathy, and to analyze the relevance between clinical phenotype and genotype in inherited myopathy.

METHODRelated genes were selected for SureSelect target enrichment system kit (Panel Version 1 and Panel Version 2). A total of 134 patients who were diagnosed as inherited myopathy clinically underwent next generation sequencing in Department of Pediatrics, Peking University First Hospital from January 2013 to June 2014. Clinical information and gene detection result of the patients were collected and analyzed.

RESULTSeventy-seven of 134 patients (89 males and 45 females, visiting ages from 6-month-old to 26-year-old, average visiting age was 6 years and 1 month) underwent next generation sequencing by Panel Version 1 in 2013, and 57 patients underwent next generation sequencing by Panel Version 2 in 2014. The gene detection revealed that 74 patients had pathogenic gene mutations, and the positive rate of genetic diagnosis was 55.22%. One patient was diagnosed as metabolic myopathy. Five patients were diagnosed as congenital myopathy; 68 were diagnosed as muscular dystrophy, including 22 with congenital muscular dystrophy 1A (MDC1A), 11 with Ullrich congenital muscular dystrophy (UCMD), 6 with Bethlem myopathy (BM), 12 with Duchenne muscular dystrophy (DMD) caused by point mutations in DMD gene, 5 with LMNA-related congenital muscular dystrophy (L-CMD), 1 with Emery-Dreifuss muscular dystrophy (EDMD), 7 with alpha-dystroglycanopathy (α-DG) patients, and 4 with limb-girdle muscular dystrophy (LGMD) patients.

CONCLUSIONNext generation sequencing plays an important role in diagnosis of inherited myopathy. Clinical and biological information analysis was essential for screening pathogenic gene of inherited myopathy.

OBJECTIVETo investigate the correlation of serum osteoprotegerin (OPG) with the progression of nonalcoholic fatty liver disease (NAFLD) and the noninvasive prediction and diagnosis of nonalcoholic steatohepatitis (NASH).

METHODSA total of 136 patients with NAFLD were enrolled, and their tissue samples for liver biopsy and serum samples obtained at 1 week after liver biopsy were collected; 83 healthy subjects without the symptoms of fatty liver disease proved by ultrasound examination were enrolled as controls. The physiological indicators including height, body weight, and waist circumference were measured, and body mass index was calculated. The biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), AST/ALT, alkaline phosphatase, gamma-glutamyl transferase, total cholesterol, triglyceride (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. Double-antibody sandwich enzyme-linked immunosorbent assay was used to determine the serum level of OPG. The rank sum test, chi-square test, t-test, one-way analysis of variance, Spearman correlation analysis, least significant difference test, and receiver operating characteristic (ROC) curve were applied for statistical analysis of various data.

RESULTSSerum OPG level was correlated with AST and TG (P < 0.05), and was highly correlated with hepatocyte fatty degeneration, ballooning degeneration, intralobular inflammation, portal inflammation, and fibrosis degree (P < 0.01). With the increasing NAFLD activity score (NAS), serum OPG level decreased, and there was a highly negative correlation between them (r = -0.928, P < 0.01). Serum OPG level was significantly lower in NASH patients than non-NASH patients. The area under the ROC curve of serum OPG level was 0.963, and according to the Youden index, its optimal sensitivity and specificity were 96.1% and 97.4%, respectively, at an optimal cut-off value of 242.96 ng/L, which suggested a high diagnostic power.

CONCLUSIONIn NASH patients, serum OPG level decreases significantly. Serum OPG level can be used as an independent predictive factor to evaluate NASH and its severity, as well as a noninvasive diagnostic index for NASH.

Objective:To explore the diagnosis and treatment of the multi-segment injury of brachial plexus and provide reference for diagnosis and treatment in clinical practice.Methods:From October, 2012 to January, 2015, 24 patients (21 males and 3 females, aged 7-46, average at 25.06±13.01 years) who suffered multi segments injury of brachial plexus were treated by surgical operations. Time from injury to surgery was 7 days to 7 months, with (2.43±2.15) months in average. The general data, injuries and surgical procedures of the patients were recorded. Muscle strength grading was used to evaluate and analyse the curative effect.Results:Twenty-four cases were followed-up for 3.1-7.2 years, with 4.3 years in average. Of the patients, 58.3% of the injuries were caused by mechanical traction. Combined injuries were counted for 83.3%, of which 62.5% combined with ipsilateral limb fractures, 20.8% (5/24) involved in the root of brachial plexus, 79.2% (19/24) with upper part of the clavicle, 91.6% (22/24) with lower part of the clavicle, 16.7% (4/24) with branches of the brachial plexus and 91.7% (22/24) with injuries of 2 segments, 8.3% (2/24) with injuries of 3 segments. At the last followed-up, 55.0% of the patients achieved better than M 3 in total muscle strength. The excellent and good rate was 70.8% in neurolysis group and 42.9% in multiple segment injury group. Conclusion:The mechanism of multi segments injury of brachial plexus is special, and the actual injury is difficult to be located. For patients with multi segments injury, surgical operation should be carried out as early as possible, and the correct surgical procedure can only be determined after the exploration of all sections of the brachial plexus.

Objective:To explore the correlation of serum albumin level at admission with clinical prognoses in patients with acute traumatic brain injury (TBI).Methods:One hundred and fifty-four patients with acute moderate-extreme severe TBI (Glasgow Coma Scale [GCS] scores of 3-12 at admission) in Department of Neurosurgery, General Hospital of Western Theater Command from January 1, 2019 to December 31, 2020 were chosen. The comprehensive clinical data of these patients were collected, including age, gender, GCS scores, serum albumin level (hypoalbuminemia defined as<35 g/L), hemoglobin level, comorbidities, treatment measures, and prognoses 6 months after discharge (poor prognosis defined as Glasgow outcome Scale [GOS] scores of 1-2, and good prognosis defined as GOS scores of 3-5). Univariate and multivariate Logistic regressions were used to identify the independent factors for clinical prognoses of these patients, and differences in poor prognosis rate, length of ICU stay, and total hospital cost were compared between different groups.Results:Among the 154 patients, 43 had poor prognosis and 111 had good prognosis. Serum albumin level at admission ( OR=0.916, 95% CI: 0.843-0.996, P=0.001) and GCS scores at admission ( OR=0.701, 95% CI: 0.594-0.828, P<0.001) were independent factors for prognosis. Patients with hypoalbuminemia ( n=70) displayed significantly higher poor prognosis rate, longer ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=84, P<0.05); specifically, in patients with GCS scores of 9-12 at admission ( n=58), those with hypoalbuminemia ( n=27) exhibited significantly higher poor prognosis rate, longer ICU stays, and higher total hospitalization cost than their non-hypoalbuminemia counterparts ( n=31, P<0.05); similarly, in patients with GCS scores of 3-8 at admission ( n=96), those with hypoalbuminemia ( n=74) had significantly higher poor prognosis rate than their non-hypoalbuminemia counterparts ( n=22, P<0.05). In patients with good prognosis, those with hypoalbuminemia ( n=56) showed significantly longer total hospital stays, prolonged ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=55, P<0.05). Conclusion:Low serum albumin level at admission is likely to lead to poor prognosis, prolonged ICU stays and increased total hospitalization cost in patients with acute TBI.

Purpose: This study aims to evaluate the efficacy and safety of a new combination treatment of vinorelbine and pyrotinib in human epidermal growth factor receptor 2 (HER2)–positive metastatic breast cancer (MBC) and provide higher level evidence for clinical practice. Materials and Methods: This was a prospective, single-arm, phase 2 trial conducted at three institutions in China. Patients with HER2-positive MBC, who had previously been treated with trastuzumab plus a taxane or trastuzumab plus pertuzumab combined with a chemotherapeutic agent, were enrolled between March 2020 and December 2021. All patients received pyrotinib 400 mg orally once daily plus vinorelbine 25 mg/m2 intravenously or 60-80 mg/m2 orally on day 1 and day 8 of 21-day cycle. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included the objective response rate (ORR), disease control rate (DCR), overall survival, and safety. Results: A total of 39 patients were enrolled. All patients had been pretreated with trastuzumab and 23.1% (n=9) of them had accepted trastuzumab plus pertuzumab. The median follow-up time was 16.3 months (95% confidence interval [CI], 5.3 to 27.2), and the median PFS was 6.4 months (95% CI, 4.0 to 8.8). The ORR was 43.6% (95% CI, 27.8% to 60.4%) and the DCR was 84.6% (95% CI, 69.5% to 94.1%). The median PFS of patients with versus without prior pertuzumab treatment was 4.6 and 8.3 months (p=0.017). The most common grade 3/4 adverse events were diarrhea (28.2%), neutrophil count decreased (15.4%), white blood cell count decreased (7.7%), vomiting (5.1%), and anemia (2.6%). Conclusion Pyrotinib plus vinorelbine showed promising efficacy and tolerable toxicity as second-line treatment in patients with HER2-positive MBC.
