Spinal cord injury (SCI) occurs most often at the peak of reproduction to young people. SCI patients faced the problems how to reproduce. The development of reproductive sciences was reviewed.

After spinal cord injury (SCI), the male reproductive functions are often seriously impaired, including dysfunction of erection, ejaculation, and abnormality of sperm qualities. With the advance of medicine, nowaday most men with SCI can finish erection, ejaculation and assisted reproduction. This article reviewed the reproductive dysfunctions in men with SCI, and discussed the relevant aspects.

Objective To study the antipyretic,anti-inflammatory and analgesic effects of Chaigeshubiao granules. Methods Animals were randomly divided into 6 groups:blank control group,indomethacin group,Fengreganmao granules group and the high, the medium and the low dosage groups of Chaigeshubiao granules ( 26, 13, 6. 5 g . kg-1 ) . Each group was administered via intragastric administration once a day for 5 days.Rat model suffering from fever by dried yeast,relieving fever of Chaigeshubiao granules was investigated;Rats with toe swelling by 1% carrageenin and mice with ear swelling by dimethylbenzene were applied to observe anti-inflammatory effects of Chaigeshubiao granules were observed;The pain models induced by 0. 6%acetic acid and the hot-plate tests in mice were used to observe the analgesic effects of Chaigeshubiao granules. Results Compared with negative control group,Chaigeshubiao granules in high dosage could obviously decrease the temperature of rat with fever induced by dried yeast 0.5 h later,and the medium dosage group decreased 4-6 h later. Moreover,Chaigeshubiao granules in high dosage could inhibit inflammatory reaction of rat with toe swelling caused by albumen at 1 h,2 h,3 h,when the medium dosage group inhibited at 2 h,3 h,4 h. The inhibition ratio of the mice with ear swelling induced by dimethylbenzene was 58.2%, 52.0% and 53.9%,respectively at the high,medium and low dose groups. And the inhibition ratio of retortion of mice by 0.6%acetic acid was 50.5%,68.8%,58.1%,respectively, at the high,medium and low dose groups. In addition,the high,medium and low dose groups reduced the pain reaction latency of mice in the hot-plate tests. Conclusion Chaigeshubiao granules have antipyretic,anti-inflammatory and analgesic actions.

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

Objective To explore the reproduction needs of men with spinal cord injury. Methods Data was collected with questionnaire. Results 57 men with spinal cord injury had urgent needs of reproduction meanwhile professional services were deficient seriously. Conclusion The professional services for reproduction can't meet the needs of persons with spinal cord injury

Objective To investigate the physical and magnetic properties and cytotoxity of 5-FAM-dextran-coated superparamagnetic iron oxide nanoparticles ( 5-FAM-dextran-Fe3 O4 ) , and to observe the cell-labeling character of these nanoparticles. Methods 5-FAM-dextran-Fe3 O4 were prepared by ultra-sonic and chemical coprecipitation method and the characteristics were evaluated. The size and distribution of 5-FAM-dextran-Fe3 O4 were measured by transmission electron microscope ( TEM) and Malvern Zetasizer. The organic structure of the coating was characterized by fourier translation infrared spectroscopy. The optical imaging ability was measured by ultraviolet visible spectrometer and the susceptibility was measured by vi-brating sample magnetometer. In vitro cytotoxities of 5-FAM-dextran-Fe3 O4 , dextran-Fe3 O4 and Fe3 O4 were detected by MTT assay. The area of labeled neuronal cells was observed by confocal microscopy after incuba-ted with nanoparticles under different magnetic intensities. One-way analysis of variance was used. Results The size of 5-FAM-dextran-Fe3 O4 was homogeneous under TEM, and the diameter ranged from 15 to 25 nm ( average=22 nm) by Malvern Zetasizer. The organic structure of the coating of Fe3 O4 was confirmed by fou-rier translation infrared spectroscopy. Ultraviolet visible spectrometer observation showed that the nanoparti-cles expressed unanimous green fluorescence under ultraviolet activation. The saturation magnetization, residu-al magnetization and coercivity of the nanoparticles by magnetometer detection were 86. 02 A · m2 · kg-1 , 15. 05 A·m2 ·kg-1 and 5414.01 A/m respectively, showing superparamagnetic character. MTT assay re-sults showed that 5-FAM-dextran-Fe3 O4 had no obvious cytotoxicity. The confocal microscopy observation in-dicated that the cell-labeled area reached the maximum under the magnetic field intensity of 500 mT ((0. 880±0.146) mm2, F=320.298, P<0.05). Conclusions 5-FAM-dextran-Fe3O4 prepared by ultra-sonic coprecipitation method have the advantages of small size, good homogeneity and magnetic property. Therefore, they might be used as the fluorescent magnetic bio-probe in laboratory and clinical studies.

Objective:To observe the occurrence and closure of iatrogenic atrial septal defect (IASD) after left atrial appendage occlusion (LAAo) and atrial fibrillation cryoballoon ablation (CBA), and to identify potential factors that may affect the occurrence of IASD.Methods:A total of 383 patients who underwent successful LAAo surgery in the Department of Cardiology at the Nanjing Hospital Affiliated to Nanjing Medical University from June 7, 2016 to December 2, 2020, and atrial fibrillation CBA surgery from December 29, 2016 to September 10, 2020 were retrospectively selected. Patients were followed up with echocardiography at 1 month, 3 months, 6 months, 1 year, and>1 year after surgery to determine the occurrence of IASD. The incidence of IASD between the two groups was compared, and clinical data between the two groups with and without IASD were analyzed to identify the relevant factors for the occurrence of IASD.Results:One month after CBA surgery for atrial fibrillation [73.8%(138/187) vs 47.9%(67/140), P<0.001], 3 months [39.0%(57/146) vs 13.6%(16/118), P<0.001], 6 months [17.7%(22/124) vs 3.6%(4/110), P=0.001], 1 year [11.8%(15/127) vs 1.8%(2/112), P=0.003], and one year later [9.8%(13/133) vs 0.9%(1/116), P=0.002], the incidence of IASD was significantly higher than those in LAAo. Compared with the non IASD group, the IASD group had a lower proportion of males [59.0%(121/205) vs 83.6%(102/122), P<0.001], and a higher proportion of paroxysmal atrial fibrillation [61.5%(126/205) vs 45.9%(56/122), P=0.006]. Logistic regression analysis found a significant correlation between women and CBA with postoperative IASD. Conclusions:Compared with LAAo, the incidence of IASD after CBA for atrial fibrillation is higher, and some IASD persist for more than 1 year after surgery. Women are significantly associated with IASD.
