OBJECTIVE To explore the improvement effect of rape pollen on androgenic alopecia mice and its mechanism. METHODS The blank group, model group, positive drug group and administration group were set up, the androgenic alopecia mice model was induced by applying 0.2% testosterone after hair removal. The hair growth rate of mice were observed by using 5% minoxidil as positive drug and 0.4 g·mL-1 rape pollen oil solution as administration group. The hair quality and follicle condition of mice were observed by scanning electron microscope(SEM) and HE staining of skin tissue, respectively. The level of VEGF and bFGF in skin were detected by immunofluorescence staining and Western blotting, while the level of serum sex hormones and reactive oxygen species were detected by ELISA. RESULTS Rape pollen could significantly promote the hair growth in mice and improve the state of mice hair scales compared with model group. Mechanism exploration experiments showed that rape pollen could not promote hair regeneration of mice by regulating hormone levels or anti-oxidative stress. However, rape pollen could increase the expression of bFGF and VEGF related to skin angiogenesis at the modeling site. CONCLUSION Rape pollen can promote hair regeneration in androgenic alopecia mice. Its mechanism may be that it promotes perifollicular vascular regeneration by increasing bFGF and VEGF level.

Objective:To explore the effect of sports training guidance based on Internet platform on the limb function and quality of life in home rehabilitation of stroke hemiplegic patients.Methods:Eighty patients with stroke and hemiplegia admitted to Beijing Rehabilitation Hospital Affiliated to Capital Medical University from June 2018 to December 2019 were selected and divided into observation group and control group with 40 cases in each group by random digits table method. The control group was given routine rehabilitation training. In addition to the regular rehabilitation training, the observation group was supplemented with home rehabilitation based on the WeChat platform for modified constraint-induced movement therapy. The limb motor function Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, Stroke-Specific Quality of Life scale (SS-QOL) score before and after intervention, and patients′ satisfaction and cares′ satisfaction score were compared between the two groups.Results:There was no significant difference in the score of FMA, UEFT, SS-QOL before intervention between the two groups( P>0.05). After discharge, the FMA score, UEFT score and physical function, physiological function, mental health, social function of SS-QOL score were (68.87±6.64),(72.38±7.33), (35.28±4.13), (36.55±4.23), (37.22±3.84), (38.23±3.44) points in the observation group and (55.25±6.20), (61.24±6.47), (28.72±4.56), (30.85±5.30), (31.28±4.63), (31.02±5.16) points in the control group, and the differences were statistically significant between the two groups( t values were 5.316-9.482, P<0.01). During the nursing period, the patients′ satisfaction and cares′ satisfaction score were 92.50%(37/40), 87.50%(35/40) in the observation group and 72.50%(29/40), 67.50%(27/40) in the control group, and the differences were statistically significant between the two groups( χ 2 values were 5.541, 4.588, P<0.05). Conclusions:The home rehabilitation based on the Internet platform for modified constraint-induced movement therapy helps to promote the recovery of limb motor function in stroke hemiplegic patients, improve the nursing satisfaction of patients and their families, and has a positive effect on improving the quality of life of patients.

Objective: To assess the association of single nucleotide polymorphisms of multidrug resistance gene 1 (MDR1) with refractory epilepsy in children. Methods: Peripheral blood samples were collected from 200 children with epilepsy and 100 healthy controls. Genomic DNA was extracted and subjected to PCR amplification, agarose gel electrophoresis and target site sequencing. Genotypes of rs1922242, rs2235048, rs10808072, rs868755 and rs1202184 loci of the MDR1 gene were analyzed. Results: No significant difference was found in genotypic distribution and allelic frequencies of the rs1922242, rs2235048, rs10808072 and rs868755 loci between the drug-resistant and drug-sensitive groups. For the rs1202184 locus, a significant difference in genotypic distribution was found (P = 0.008). No significant difference was found in the frequencies of various haplotypes between the two groups. Conclusion Genotypes of the rs1202184 locus of the MDR1 gene are associated with refractory epilepsy in children, for which the AA genotype plays a dominant role.

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.

Objective To summarize the correlation between clinical manifestations and imaging characteristics of schizencephaly in order to provide a basis for the diagnosis and prognosis.Methods Thirty-five outpatients with schizencephaly diagnosed at Department of Pediatric Neurology of Henan Provincial People's Hospital from January 2009 to May 2015 were retrospectively selected,and they were divided into different groups (patients with unilateral lesions or bilateral lesions) according to their cranial magnetic resonance imaging (MRI) features.The clinical manifestations were compared between different groups.Results Of 35 patients,19 (54.3％) patients were male and 16 (45.7％) patients were female.Twenty-four patients were found with unilateral lesions (68.6％),including 16 cases (66.7％) with hemiparesis and 8 cases(33.3％) with no motor impairment.Mental retardation was observed in 8 patients (33.3％) and 6 patients (25.0％) showed speech impairment.Eleven patients were found the bilateral lesions (31.4％),including 5 patients (45.4％) with tetraparesis,4 patients (36.4％) with hemiparesis,and 2 paticnts (18.2％) with no motor impairment.Mental retardation was observed in 9 patients (81.8％) and 9 patients (81.8％) showed speech impairment.There were significant differences in motor impairment,mental retardation and speech impairment between the unilateral lesion group and bilateral lesion group (Z =-2.40,P =0.002;x2 =7.09,P =0.012;x2 =9.94;P =0.003).Epileptic seizure occurred in 18 patients (51.4％).Binary Logistic regression analysis indicated that cortical dysplasia beyond the cleft and open-lip lesions were the major risk factors for seizures (OR =4.44,2.73;P =0.005,0.029).Imaging characteristics:there were closed-lip lesions in 10 patients (28.6％),open-lip lesions in 21 patients (60.0％) and open/closed-lip lesions in 4 patients (11.4％).Anatomic localization of all clefts was found in the frontal lobes in 19 patients (54.3％),in frontoparietal lobes in 11 patients (31.4％),in parietal lobes in 2 patients (5.7％),and in occipital lobes in 3 patients (8.6％).After 1-6-year follow-up,12 patients treated with antiepileptic drug were seizure-free (all with unilateral lesions),and 6 patients had refractory epilepsy (3 patients with bilateral lesions).Conclusions Schizencephaly is a rare structural disorder of cerebral cortical development.Those with bilateral lesions are usually manifested with severe motor,speech impairment and mental retardation and their prognosis is poor.Schizencephaly patients complicated with cortical dysplasia beyond the cleft or open-lip lesions are more easily attacked by seizures.MRI plays an important role in the diagnosis and prognosis judgment of schizencephaly.

Objective Taking the hippocampus as seed,to investigate the characteristics of white matter in patients with major depressive disorder (MDD) and bipolar depression (BD).Methods 33 MDD and BD according with the Fourth Edition of Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria,accompanying with 33 healthy controls (HC) matching with age,sex and education years were analyzed.All subjects underwent MRI scanning,acquiring diffusion tensor imaging (DTI)data.Taking the hippocampus as seed,to adopt diffusion tensor fiber tracing by DSIstudio to obtain and calculate basic index of DTI,then find the differences among three groups;furthermore,calculating the fiber number (FN) evaluating the connective strength between areas between hippocampus and other areas.Additionally,Pearson correlation analysis was used to analyses the relationship between the difference index and clinical characteristics.Results Compared with HC,radial diffusivity (RD) in the left hippocampus had significant difference (P=0.014)in BD group.While no significance parameter was found between MDD group and the other two groups.Compared with HC group,the reduction of FN value in MDD patients mainly exists in left inferior frontal gyrus(0(0,25)vs.0(0,1),P=0.018)and left middle occipital gyrus (38.6±6.7 vs.26.9±25.6,P=0.015).Compared with HC,FN value of BD increase in the left parahippocampal gyms (47.2± 24.0 vs.65.8 ± 30.1,P=0.007) and tongue gyrus (50.4 ± 33.2 vs.74.2 ± 35.9) in BD (P=0.012).Pearson correlation analysis found that RD mean of left hippocampus remain positively correlated with the duration of disease in BD group (r=0.418,P=0.016).Conclusions BD has some changes mainly in the left hippocampus,which exists myelin sheath degeneration and the alteration of white matter fiber connected with left parahippocampal gyrus and tongue gyrus,while MDD shows some differences of connectivity between left hippocampus and frontal lobe,and between right hippocampus and occipital lobe as well.

Objective To investigate the status and needs of training medical staff in county-level medical institutions in Guangxi to provide preferences for developing training programs. Methods Self-designed questionnaires were used to investigate a random sample of 477 medical staffs in 9 county-level medical institutions including People's Hospi-tals, Chinese Medical Hospitals, Maternity and Child Care Hospitals in Wuming, Liujiang, Rongxian counties. Re-sults 13% of the medical staffs had never participated in training; 28.1% of them were trained once a month; 50.7% of them were trained for less than a week. 39.4% of them expected to receive training once a year , 21.6% expected a week to half a month and 21.8% expected three months to six months. 60.4% of them expected to receive new knowl-edge and technique training. 73.6%of them expected to go to provincial hospitals for training and 57% of them expect-ed to receive extension study. Conclusion There are differences between medical staff training needs and status. Exist-ing questions are incomplete training coverage, too dense training frequency ,too short training period, medical staffs urgently need the training of continuing professional development, new technology and professional knowledge, and training effect is not obvious. We can establish medical staff in-service training incentives ,increase medical staffing and reform training methods to encourage and attract more medical staff to attend training.
