BACKGROUND: Magnetic resonance diffusion tensor imaging (MRDTI) may non-wounded detect damage of fiber in white matter and becomes an effectively way to evaluate upper motor neuron(UMN) impairments.OBJECTIVE: To investigate the clinical significance of MRDTI on amyotrophic lateral selerosis(ALS).DESIGN: Case contrast observation.SETTING: Department of Neurology, Renmin Hospital of Wuhan University.PARTICIPANTS: Twenty ALS patients were selected from Department of Neurology, Renmin Hospital of Wuhan University from April to December 2005. There were 11 males and 9 females, and their ages ranged from 33 to 73 years with the mean age of (51±10) years. All subjects met the diagnostic criteria of ALS set by World Neurology League.Other 15 healthy subjects were collected as control group. There were 8 males and 7 females, and their ages ranged from 31 to 73 years with mean age of (50±11) years. All subjects provided the confirm consent.METHODS: Based on level of upper and lower motor neuron impairments, ALS patients were divided into UMN impairment group (n =16) and lower motor neuron group (n =4). Functional scores of ALS, illness developing velocity and pyramidal sign scores were performed, respectively. All subjects were scanned with DTI at axial view. Regions of interest [subcortical white matter of precentral gyrul and postcentral gyrul (Pre-CG/Post-CG), centrum semiovale and frontal white matter (CS/FWM), peripheral lateral cerebral ventricle, posterior limb of internal capsule (PIC), cerebral peduncle (CP), genu corpus callosum and splenium corpus callosum (GCC/SCC) and dorsal thalamus (DT)] were selected to measure fractional anisotropy (FA) and apparent diffusion coefficient(ADC).MAIN OUTCOME MEASURES: Correlations among FA, ADC, functional score of ALS, illness developing velocity and pyramidal sign scores.RESULTS: Twenty patients and 15 subjects in the control group were involved in the final analysis. ① FA was reduced and ADC increased in the posterior limb of the internal capsule in patients with UMN signs compared to healthy volunteers (t =3.452, 2.670; P ＜ 0.01, 0.05). Nonparametric tests revealed that there was a trend toward reduced FA in the posterior limb of the internal capsule in B group compared to controls (U =11, P =0.057). ② In UMN impairment group, FA in the posterior limb of the internal capsule was positively correlated with the ALS rating scale (r =0.577, P ＜0.05) and negatively correlated with pyramidalsign scores (r = -0.789, P ＜ 0.01 ),CONCLUSION : The impairment of pyramidal tracts can be noninvasively evaluated by diffusion tensor MR in vivo, thus providing useful information in diagnosing and further understanding MND.

Objective To study the effect and possible mechanism of Apelin in candate on the pain behavior of rat. Methods Tail flick latency(TFL)of rat was taken as pain threshold and radiant heat as nociceptive stimulus. Microinjected Apelin into rat's caudate to observe the effect of Apelin on modulating of pain in CNS and then to study the interaction between Apelin and morphine in modulation of pain.And the contents of cAMP and cGMP in candate tissue and blood plasma were detected.Results Compared with control groups,the pain threshold of rat decreased when Apelin Was injected into caudate alone.Injected 0.5μl Apelin of 10~(-4) moL/L into rat caudate 10 min later,the pain threshold of rat Was reduced(-9.22±1.26)%and 40 min later(-16.95±1.46)%compared with normal saline group(-0.32±1.2)%,(0.17±0.80)%),and it had statistical significance(P<0.01).The contents of cAMP in caudate Was(14.08±2.25)nmol/g and blood plasma(19.94± 4.43)nmol/L compared with normal saline(133.05±20.41)nmol/g,(38.66±6.73)nmol/L,and they had statistical significance(P<0.01).Conclusions Apelin can facilitate the pain behavior of rat induced by radiant heat stimulus and consequently plays a hyperalgesia role in CNS.Apelin may have interaction with morphine and display its hyperalgesia effect through the intracellular second messenger cAMP.

Objective:To experimentally intervene safe injection by medical staff in basic-level hospitals and observe the recent and long-term effect atfer the intervention and to provide practical measures to improve safe injection. Methods:We used random sampling methods to set up groups in county hospitals and township hospitals of Hunan Province, and offered lectures, delivered safe injection guide, brochure and on-site guidance in the experimental group. We surveyed the 2 groups atfer the intervention at 1 month and 6 months to compare the effect of unsafe injection behaviors and safe injection behaviors. Results:One month after the intervention, the unsafe injection rate in the experimental group decreased from 27.8%to 21.7%, while in the control group injection the unsafe injection rate rose from 26.0%to 27.9%, with signiifcant difference (P<0.01). Six months atfer the intervention, the unsafe injection rate in the experimental group declined to 18.4%while the unsafe injection rate in the control group also dropped to 22.4%, with signiifcant difference (P<0.01). Unsafe injection rate was decreased in the experimental group at different intervention points, with signiifcant difference (P<0.01). The safe injection behavior scores in the experimental group were higher than those in the control group after the intervention of 1 month and 6 month intervention (P<0.01);the experimental group got higher scores atfer the intervention (P<0.01). Conclusion:Training of safe injection, distribution of safe injection guide, and comprehensive intervention model can significantly change the primary care practitioners’ behaviors in unsafe injections and it is worth promoting.

OBJECTIVETo investigate the composition and resistance of main pathogens isolated form Lower respiratory tract in coalminer's pneumoconiosis patients complicated with infection to provide the basis for clinical treatment.

METHODCoalminer's pneumoconiosis patients complicated with infection during 2009 to 2010 were divided into mechanical ventilation group and non mechanical ventilation group. Specimens were obtained from lower respiratory tract by fibrobronchoscopy with protected specimen brush in patients of both groups to perform isolation, culture, identification and susceptibility test of pathogen.

RESULTTotal 111 patients were enrolled, 36 of them in mechanical ventilation group and 75 patients in non mechanical ventilation group. The pathogenic bacteria detection rate of patients in mechanical ventilation group was significantly higher than that of patients in non mechanical ventilation group (88.9% vs. 46.7%, P < 0.01). In non mechanical ventilation group, Mycobacterium tuberculosis was detected in 3 patients, and 27 strains of G- bacilli, 3 strains of G+ coccus, and 2 strains of fungus; and 26 strains of G- bacilli, 3 strains of G+ coccus, and 3 strains of fungus were detected in mechanical ventilation group. There was no significant difference in term of strains between the two groups (P > 0.05). Rate of resistance to main antibiotics of patients in mechanical ventilation group was higher than that of patients in non mechanical ventilation group.

CONCLUSIONResistance of pathogenic bacteria isolated from lower respiratory tract was severe in coalminer's pneumoconiosis patients complicated with infection, which was higher in patients treated with mechanical ventilation than patients without mechanical ventilation. Mycobacterium tuberculosis and fungal infection and increasing resistance prompted that clinicians must attach importance to rational drug use and keep to monitoring bacterial resistance.

A squalene synthase gene cloned (GuSQS1, accession number in GenBank database: AM182329) from Glycyrrhiza uralensis was transferred into G. uralensis via Agrobacterium rhizogenes A4 for investigating biosynthesis pathway and enhancing synthesis of glycyrrhizic acid (GA). Hypocotyl explants from G. uralensis were infected with A. rhizogenes A4 containing GuSQS1 gene to induce the hairy roots. The hairy root lines established were selected in medium containing 0.8 mg x L(-1) phosphinothricin (PPT) and analyzed by PCR and southern blotting. The transgenic hairy roots were cultured in liquid MS medium. GA contents in transgenic hairy roots were detected by HPLC. Results showed that maximal GA content in transgenic hairy root lines was 3.6 times as high as in wild type hairy roots.

Objective: To determine health risk behaviors and cluster patterns among adolescents from four minorities in rural of Wuling mountainous area, and to provide a reference for health education for adolescents in ethnic minority areas. Methods: Totally 4 162 teenagers from 8 rural middle schools of Xiangxi Tujia and Miao Autonomous Prefecture, Dong Autonomous County of Tongdao, Huaihua, Bai Minority Village of Sangzhi County, Zhangjiajie, were selected with multi-stage stratified random cluster sampling and surveyed with a questionnaire to collect information on health risk behaviors from September to October, 2018. Cluster patterns of health risk behaviors were analyzed by sex by two-step cluster method. Results: The occurrence rates of the behaviors of the adolescents from four minorities of smoking, drinking, walking violations, unsafe swimming, fighting, suicide idea, feeling lonely constantly, frequent sleeplessness, depression, internet addiction were 18.9%, 31.0%, 49.6%, 32.3%, 28.6%, 18.3%, 16.3%, 12.4%, 16.3%, 6.7% respectively, among which the highest occurrence rates were Tujia teenagers’ fight(31.4%), Miao teenagers’ unsafe swimming(45.1%), Dong teenagers’ drinking(34.8%), Bai teenagers’ walking violation(52.9%). And the differences were statistically significant(P<0.05). Among the lowest risk group, there were 322 male students (16.4%) and 496 female students (22.5%); Among the moderate low group, there were 377 male students (19.3%) and 536 female students (24.3%); Among the implicit behavior high risk group, there were 518 male students (26.5%) and 758 female students(34.4%);Among the explicit behavior high risk group, there were 741 male students (37.8%) and 414 female students(18.8%). 23.1% of teenagers engaged in four or more types of health risk behaviors, with male higher than that of female(χ2=183.52, P<0.01), and the rate of Miao teenagers (28.2%) was the highest. Conclusion Health risk behaviors among minority adolescents in Wuling rural areas are prevalent and varied in ethnicity. Clustering of explicit risk behaviors in boys and implicit risk behaviors in girls were obvious. The hierarchical guidance and comprehensive intervention should be carried out on the basis of the characteristics of different minority teenagers’ health risk behaviors.

Objective To characterize the baseline status of Chinese diabetic patients based on data derived from Chinese cohort from SOLVETM study.Methods Patients with type 2 diabetes initiating basal insulin detemir at the decision of the physician were eligible for the study.Data on demographics,medical history,glycemic profile and treatment regimen at baseline were collected by physicians.Results A total of 3272 patients [female 42％,male 58％,mean age (56.2 ± 10.8) years] were included in the study.Their BMI was (25.3 ± 3.3) kg/m2.The duration of diabetes was 4.0 (0.1-27.0) years,and the duration of treatment with oral antidiabetic drugs (OADs) was 3.0(0.0-20.2) years.The proportions of subjects with diabetic macro-and micro-vascular complications were 15.8％ (515 cases) and 27.1％ (866 cases),respectively.The hemoglobin Al c (HbAl c) at baseline was (8.33 ± 1.70) ％,and the fasting blood glucose (FPG) was (9.5 ± 2.6) mmol/L.Conclusions A large proportion of patients with type 2 diabetes remain in poor glycemic control,and the prevalence of diabetic complications is high,which requires optimal therapeutic strategy for the patients with suboptimal glycemic control.

BACKGROUND: Cardiovascular (CV) disease is the leading cause of morbidity and mortality in adults with type 2 diabetes (T2D). The aim of this study was to determine the CV risk in Chinese patients with T2D based on the 2019 European Society of Cardiology (ESC) and the European Association for the Study of Diabetes (EASD) guidelines on diabetes, pre-diabetes, and CV diseases. METHODS: A total of 25,411 patients with T2D, who participated in the study of China Cardiometabolic Registries 3B study, were included in our analysis. We assessed the proportions of patients in each CV risk category according to 2019 ESC/EASD guidelines. RESULTS: Based on the 2019 ESC/EASD guidelines, 16,663 (65.6%), 1895 (7.5%), and 152 (0.6%) of patients were included in "very high risk," "high risk," and "moderate risk" categories, respectively. The proportions of patients in each category varied based on age, sex, body mass index, and duration. While 58.7% (9786/16,663) of elderly patients were classified to "very high risk" group, 89.6% (3732/4165) of patients with obesity were divided into "very high risk" group. Almost all patients with a duration of diabetes >10 years had "very high risk" or "high risk." However, 6701 (26.4%) of Chinese T2D patients, who had shorter duration, and one or two risk factors, could not be included in any category (the "unclear risk" category). CONCLUSIONS In China, most patients with T2D have "very high" or "high" CV risk based on 2019 ESC/EASD guidelines. However, the risk of patients in "unclear risk" group needs to be further classified.
