Objective:In the teaching practice based on "Internet+", there are relatively few studies on the transformation of learners' learning styles. This paper focuses on the practical factors that may affect the change of students' learning style in the teaching process of blended learning.Methods:Taking students from Batch 2017 of Inner Mongolia Medical University as the teaching objects who taught by blended learning, by means of questionnaire survey, interview, course performance analysis and other methods, this paper discusses the influence of students' learning style on learning effect and possible influencing factors in the process of blended learning.Results:In the process of teaching, students' learning styles have a profound impact on the learning effect to some extent. Therefore, the subjective and objective factors that affect students' learning style should be paid attention to.Conclusion:With the popularization of "Internet + education", the ways and environment of traditional education have undergone great changes. In the process of blended learning reform, teachers should pay more attention to learning styles of students, so as to better improve the teaching effect.

OBJECTIVETo identify the mutation of the GABA(A)-receptor gamma 2 subunit gene (GABRG2) in a Chinese family with generalized epilepsy with febrile seizures plus (GEFS+ ) and analyze the genotype-phenotype correlations and its inheritance.

METHODSGenomic DNA was extracted from peripheral blood lymphocytes of the proband and other available members in the GEFS+ family. The coding regions and flanking intronic regions of the GABRG2 gene were screened for mutations using polymerase chain reaction (PCR) and direct DNA sequencing.

RESULTSThere were 7 affected members in the three-generation family, in which one with febrile seizures (FS) and six with febrile seizures plus (FS+ ). This family was consistent with the diagnostic criteria of GEFS+ . The nonsense mutation c.1287G to A (p.W390X) in the GABRG2 gene was initially identified in the proband. Seven affected members (6 FS+ and 1 FS) and one unaffected member carried the mutation. The nonsense mutation c.1287G to A/p.W390X in the GABRG2 gene was co-segregated with the GEFS+ family. The penetrance rate was about 87.5%(7/8).

CONCLUSIONThis GEFS+ family was consistent with autosomal dominant inheritance with incomplete penetrance. GABRG2 mutation is also a disease-causing mutation in Chinese GEFS+ patients. The p.W390X mutation has not been reported previously.

Objective: To investigate the clinical features, laboratory characteristics and genetic diagnosis of Kabuki syndrome (KS). Methods: Between September 2014 and September 2016, seven children with clinically diagnosed KS from the neurology department, Beijing Children Hospital, Capital Medical University were included in this study. Three of them were male and 4 were female aged from 19 days to 6 years and 4 months with a median age of 3 years and 1 month. The clinical features, laboratory and imaging materials, gene tests were analyzed prospectively. Results: Clinical manifestation: cephalofacial anomaly: all seven cases had unusual facies presented as long palpebral fissures, eversion of the lateral third of lower eyelids, arched eyebrow with brow sparse, epicanthus, orbital hypertelorism, short columella with broad and depressed nasal tip; six cases presented with palatal arch deformity; four cases presented with ptosis; three cases presented with dental abnormalities and hearing impairment respectively; two cases presented with strabismus and earlap malformation respectively; one case presented with amblyopia. Six cases presented with skeletal anomalies. Six cases presented with dermatoglyphic anomalies. All cases presented with mild to moderate mental retardation. Three cases presented with short stature. Four cases presented with cardiac abnormalities. Three cases presented with epileptic seizures. Others: three cases presented with dystonia and neonatal hyperbilirubinemia respectively; two cases presented with feeding problem and hypoglycemia respectively; one case presented with micropenis and fetal finger pads respectively. All seven patients received magnetic resonance imaging (MRI) tests, and none demonstrated an abnormal finding. Five patients received electroencephalogram (EEG) tests, and three of them presented with seizures and EEG abnormalities. Five patients received genetic testing and all presented with KMT2D heterozygous mutations which were new mutations proved by parents validation (three cases were nonsense mutations, one was frameshift mutation, one was missense mutation). All patients received rehabilitation training and symptomatic treatments. Three patients presented with epileptic seizures received antiepileptic therapy. At a median follow-up of 11 months (from 4 months to 2 years), one patient died, one lost to follow-up and five had improved intellectual and physical development. Epileptic seizures were controlled or reduced significantly in three patients presented with epileptic seizures. Conclusions KS is a multisystem disease with complicated manifestations, which needs a combination of various diagnosis and treatments. Genetic testing can help determine the diagnosis. Unusual facies and mental retardation are the main clinical features and diagnostic clue. It is important to improve prognosis through increasing the knowledge of KS, early diagnosis, and treatment.

Objective To evaluate the efficacy and safety of two forms of preparations of dexamethasone palmitate in the treatment of rheumatoid arthritis (RA).Methods A multicenter,double-blind,randomized,parallel-group clinical trial was carried out according to good clinical practice (GCP).A total of 237cases of RA patients with mild to moderate knee swelling were randomly divided into the treatment group (n=118 ) or the control group (n=119) and were treated with two kinds of dexamethasone palmitate 8 mg injection respectively.The primary efficacy endpoints were the circumference of the knee joint at the upper and the lower edge after the intra-articular injection.The secondary efficacy endpoints were joint tenderness index and patients general assessment.The adveme events were recorded.Analysis of covariance,t test or Wilcoxon test,x2 test or Fisher exact test were used for statistical analysis.Results The upper edges of the treatment group and the control group after treatment were (37.2±3.3) cm and (36.4±3.9) cm respectively,and the lower edges of the two groups were (34.4±2.9) cm and (33.9±3.4) cm respectively.They were all significantly smaller than the edges before treatment [(38.1± 3.3) cm and (37.3±4.0) cm of the upper edges,(35.1±3.0)cm and (34.6±3.6) cm of the lower edges respectively ) (P＜0.O1)].After treatment,the joint tenderness index were improved (P＜0.01).A total ratio of great improvement and improvement of patients general assessment of the two group patients were 67.5％ (79/117) and 74.8％ (86/115) respectively.No statistical significant difference was found in all primary and secondary efficacy endpoints between the two groups (P＞0.05).During the clinical trial,the incidence of adverse events related to the treatment of two groups were 4.2％ and 6.8％,without any significant difference (P＞0.05).Conclusion New preparation of dexamethasone palmitate has the same efficacy and safety as the imported producted in the treatment of RA.The circumference of the knee joints at the upper and the lower edge may be used to assess the effects of intra-articular injections.

Objective To investigate the clinical characteristics of paraneoplastic syndrome with prominent osteoarticular involvement. Methods The clinical materials of 20 patients with paraneoplastic syndrome with prominent osteoarticular involvement were collected. The characteristics of clinical manifest-ations, laboratory tests and imagines were analyzed. Results Among the 20 patients, 16 were male and 4 were female, with a mean age of 44.5 years and a median course of 6 months. Ten cases were associated with hematological tumor and 10 cases were associated with solid tumor. Eleven cases presented as peripheral arthritis (7 cases of polyarthritis, 4 cases of oligoarthritis/monoarthritis), 5 cases presented with hypertrophic osteoarthropathy (HOA) and 4 cases presented with tumor-induced osteomalacia (TIO). Three cases were acute lymphocytic leukemia, 2 cases were multiple myeloma, 1 case was lymphoma, and 1 case was bone tumor in polyarthritis. Four oligoarthritis cases were all associated with acute lymphocytic leukemia. All 5 cases of HOA were associated with lung cancer. All 4 cases of TIO were associated with tumor of mesenchymal tissue. Extra-articular manifestations presented in 14 cases and inflammatory markers increased in 15 cases. anti-cyclic cirullinated peptide (anti-CCP) antibodies was low titer positive in only 1 case and other parameters including rheumatoid factor (RF), anti-CCP antibodies, antinuclear antibodies spectrum (ANAs) and human leukocyte antigen (HLA)-B27 were negative. Multiple bone imaging abnormalities appeared in 15 cases. Conclusion Osteoarticular manifestations may be the first symptom of malignancy and difficult to diagnose. It is necessary to be highly aware of potential malignancy.

Objective:To summarize the clinical characteristics and genetic features of tyrosine hydroxylase deficiency(THD) caused by TH gene variants for the improvement of the understanding of the disease. Methods:The clinical and genetic data of 33 children with THD caused by TH gene variants were diagnosed in the Department of Neurology of Beijing Children′s Hospital, Capital Medical University from May 2011 to January 2020 and their data were retrospectively collected and analyzed. Results:There were 19 females and 14 males.The age at onset was ranged from 0 to 6.3 years.13 patients developed diseases, accompanied with fever after infection, and 1 patient suffered from hypoxia, 19 patients suffered from no predisposing factors.There were 7 mild TH-deficient dopa-responsive dystonia cases, 16 severe TH-deficient infantile parkinsonism with motor delay cases and 10 very severe TH-deficient progressive infantile encephalopathy cases.Clinical symptoms were fluctuating, including 26 cases of diurnal fluctuation, 22 cases of infection aggravation, and 30 cases of fatigue aggravation.The initial symptoms included tiptoeing and numbness in the limbs(7 cases), motor development retardation or degression (26 cases), fremitus (8 cases), ptosis (2 cases), and status dystonicus (3 cases). Other clinical features had hypermyotonia (23 cases), hypomyotonia (27 cases), decreased movement (27 cases), decreased facial expression (24 cases), fremitus (18 cases), tiptoeing (20 cases), talipes equinovarus (7 cases), ptosis (8 cases), oculogyric crisis (10 cases), salivation (21 cases), dysphagia (12 cases), dysarthria (16 cases), dyspnea (3 cases), increased sleep (10 cases), decreased sleep (5 cases), irritable mood (15 cases), apathetic mood (2 cases), profuse sweating (8 cases), and status dystonicus (6 cases). A total of 6 patients′ right limbs were more severe, and 14 patients′ lower limbs were more severe.Eight patients had family history, and Levodopa treatment was effective for all patients.Ten patients suffered side effects, including dyskinesia and irritability.Four patients were lost follow-up, and 29 patients were followed up between 0.8 and 13.2 years old until Ja-nuary 2020.Totally, 22 patients almost had no such symptoms.Twenty-five TH gene pathogenic variants were discovered in 33 patients.There were 13 novel variants (c.1160T>C, c.1303T>C, c.887G>A, c.1084G>A, c.1097A>T, c.734G>T, c.907C>G, c.588G>T, c.992T>G, c.755G>A, c.184-6C>T, c.1510C>T, c.910G>A) and 2 patients had c. 910G>A variant.Meanwhile, there were 5 hot variants [c.698G>A(13 cases), c.457C>T(9 cases), c.739G>A(6 cases), c.1481C>T(4 cases), c.694C>T(3 cases)]. c.910G>A(2 cases) may be the foun-der variant of Chinese population. Conclusions:THD caused by TH gene variant mostly onsets from infant, with complex clinical features.Most of these patients were severe, and only a few were very severe and mild.Very severe and mild symptoms were easily misdiagnosed.Levodopa treatment was obviously effective.A possible founder variant of Chinese population (c.910G>A) was found.c.698G>A and c. 457C>T mutations mainly appeared in patients with severe and extremely severe THD, while c. 739G>A mainly appeared in patients with mild THD.

Objective:To explore the current status of mental workload and its relationship with work engagement and fatigue, as well as the impact path among the three.Methods:Clinical nurses from six tertiary hospitals including Shanghai Traditional Chinese Medicine Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, etc. were selected to conduct a cross-sectional survey using convenience sampling method from February to March 2020. They were investigated by general information questionnaire, NASA Task Load Index (NASA-TLX), Utrecht Work Engagement Scale (UWES), and Fatigue Scale-14 (FS-14).Results:The total mental workload score of 776 clinical nurses was 76.50(69.00, 84.00). Single factor analysis showed that clinical nurses of different ages, marriage and childbirth status, education level, professional title and working years had different mental workload ( Z = -2.61, H values were 10.22-22.41, all P<0.01). Bivariate analysis revealed that the mental workload of clinical nurses was positively correlated with work engagement ( r = 0.27, P<0.01) and fatigue ( r = 0.23, P<0.01), and work engagement and fatigue were negatively correlated ( r = -0.23, P<0.01). Mediation effect analysis demonstrated that mental workload had a positive predictive effect on fatigue ( β = 0.39, P<0.01) and work engagement ( β = 0.35, P<0.01); the suppressing effect of work engagement between mental workload and fatigue, the absolute value of the ratio of the suppressing effect to the direct effect was |-0.17/0.39|. Conclusions:The mental workload of clinical nurses is at relatively high level. Hospital administrators can partially improve the fatigue state of clinical nurses with high mental load through the adjustment effect of work engagement.
