Objective To investigate the efficacy and safety of low-dose and standard-dose intravenous alteplase for acute ischemic stroke. Methods The patients with acute ischemic stroke treated with intravenous alteplase from August 2012 to January 2016 were analyzed retrospectively. According to the dosage of the drug, the patients were divided into either a low-dose group (0. 6-0. 8 mg/kg) or a standard-dose group (0. 9 mg/kg). The efficacy was evaluated with the modified Rankin Scale (mRS) at 90 days, and a favorable functional outcome was defined as mRS 0-1. The safety was evaluated by the mortality at 90 days and the incidence of symptomatic intracerebral hemorrhage (SICH) within 7 d after onset. Results A total of 790 patients were enrolled, including 612 in the low-dose group and 178 in the standard-dose group. There was no significant difference in each baseline clinical data between the 2 groups. Compared with the standard-dose group, there was no significant difference in the good outcome rate of the small-dose group at day 90 (35. 6% vs. 37. 6% ; χ2 = 0. 872, P = 0. 35) and mortality (5. 1% vs. 6. 2% ;χ2 = 2. 173, P = 0. 14), but the incidence of SICH was significantly lower (1. 8% vs. 5. 1% ; χ2 = 5. 875, P =0. 015). Conclusion The efficacy of low-dose intravenous alteplase for acute ischemic stroke is equivalent to the standard-dose and the safety is better.

CD38 is a multifunctional enzyme expressed in a variety of mammalian tissues, its catalytic activity was involved in a wide range of physiological processes. Based on the reported inhibitor of human CD38 NADase, 33 purine derivatives were designed and synthesized. The biological activity assay showed that compounds 20 and 38 exhibited almost the same extent of inhibitory activities on human CD38 NADase as the lead compound H2. The results also revealed that small substituents at C-6 of purine ring gave no obvious effect on inhibitory activity, but phenylpropionyl moiety at N-2 could affect the binding mode of the compound with CD38. This study provides a reliable basis for future rational design of inhibitors for CD38.

31 patients with cysticercosis of cerebral ventricles verified by operation or pathological investigation were reported. All patients were between 7 and 64 years of age and 14 were females. All had a single cyst. Since 29 patients (94%) were without a history of intestinal taeniasis, it was proposed that most patients of cysticercosis of cerebral ventricles were caused by hetero-infection and the entrance of Cysticercus into brain ventricle was through choroid plexus along the cerebro-spinal fluid. This is probably the reason why it occurs mostly in the 4th ventricle. The clinical manifestation of cysticercosis of cerebral ventricles were paroxysmal headache and vomiting caused by increased intracranial pressure. Ventricu-lography and CT scanning have considerable diagnostic value. Removal of Cysticercus by surgical operation is successful (Figs. 1 - 8).

Objective:In this study, a gait acquisition and analysis system is developed to provide a cheap, easy-to-use solution for quantitative recording and analysis of patients' gaits.Methods:From April 2017 to October 2018, we collected the gait data of 19 patients with knee osteoarthritis and 19 healthy volunteers in the orthopaedic outpatient department. Among 19 patients, there were 9 males and 10 females, aged 50.1±9.4 years old. Among 19 healthy volunteers, there were 8 males and 11 females, aged 50.7±10.3 years old. Then, from the collected gait data, the static gait features such as gait speed, step length, stride, and dynamic gait features were automatically calculated, and the statistical difference analysis was finished to determine the correlation between these quantitative gait features and knee osteoarthritis.Results:Firstly, the gait data collected by the depth camera was compared with the data from the multi infrared camera-based motion analysis system (gold standard). The average angle error of the collected knee joint angle was 0.98 degrees, which proved the correctness of the gait data recorded by the depth camera. The statistical difference analysis of gait characteristics between the patient group and the healthy group showed that the gait characteristics with P<0.05 included: gait speed ( r=-0.922, P<0.001), step length ( r=-0.897, P=0.004), stride ( r=-0.914 , P<0.001), dynamic characteristics of angle of knee joint ( r=0.775, P=0.001). Conclusion:The gait acquisition and analysis system based on the depth camera can accurately record and store the gait data of the patients with knee osteoarthritis. Moreover, the extracted quantitative gait features have statistical differences between the patients and the healthy group, which is helpful for the gait analysis of bone joint.

Objective:To investigate nurses' knowledge, attitude and behavior status about the safety management of enteral nutrition tube in a tertiary Class A hospital in Beijing.Methods:A self-designed questionnaire based on reliability and validity was used. Besides, a convenient sampling method was used to select 309 nurses working on enteral nutrition from the hospital.Results:Nurses scored (28.58±6.09)for knowledge, (37.65±5.03)for attitude and (70.01±5.45)for behavior. The percentage of average scores in the three indicators were 57.16%, 94.13% and 93.35%. According to the single factor analysis, the score of behavior differed among nurses with different working years( F=23.61, P=0.032). The score of knowledge differed among nurses with different titles( F=4.48, P=0.012). Besides, the frequency of tube feeding operations had great effects on nurses′ knowledge and behavior ( F=9.64, P<0.001; F=34.59, P=0.018). But there was no statistical difference in the knowledge, attitude, and behavior scores among nurses trained at different frequencies( F=0.85, P=0.497; F=12.56, P=0.231; F=18.97, P=3.479). Conclusions:Nurses have a positive attitude towards the safety management of enteral nutrition tube, but their knowledge level is poor and their behavior needs to be further regulated. It is necessary to carry out relevant training to standardize clinical operations and ensure the safety management of enteral feeding tube.

Objective To explore the correlation between ostiomeatal complex(OMC)variation, nasal septum deviation and nasosinusitis with CT imaging.Methods The clinical and imaging data of 256 patients undergoing nasal and paranasal CT examination from June 1, 2015 to May 30, 2016 were retrospectively analyzed. Patients with paranasal sinus fractures, tumors and artifacts were not included in this study.Taking the image of standard coronal MPR built with thin axial sections at the level of middle of semilunar fissure as observing image,and the direction,location and extent of OMC variations were observed and recorded. The patients were divided into two groups according to the presence or absence of nasal septum deviation.OMC mutation,the incidence of unilateral mutation,incidence of paranasal sinusitis and the incidence of unilateral bilateral nasal sinusitis between the two groups was analyzed by χ2test with two independent samples. Then according to the presence or absence of OMC mutation, the patients were divided into two groups.The incidence of paranasal sinusitis and bilateral paranasal sinusitis were compared between the two groups. Results Two hundred and fifty six cases of CT imging of parannasal sinus were included in the study,96 cases were with nasal septum deviation, 160 were with non-deviation of nasal septum. The incidence rate of OMC variation between the two groups showed significant difference(χ2=38.40,P<0.05).The incidence rate of unilateral and bilateral OMC variation showed significant difference(χ2=13.70,P<0.05),among which 54 were unilateral variations,50(92.6%)variations were located at the same side of nasal deviation(side of the nasal cavity widened).The incidence rate of sinusitis between the two groups showed non-significant difference(χ2=0.50,P>0.05).The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=2.25,P>0.05).Of the 256 cases,128 were with OMC variations,and 128 were with non-OMC variation.The incidence rate of nasosinusitis between the two groups showed non-significant difference(χ2=0.56,P>0.05). The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=3.57,P>0.05). Conclusion Ipsilateral OMC variation occurred in nasal septum deviation might be a compensation to nasal cavity widening while not a obstructive factor in causing nasosinusitis.
