Objective To investigate the effect of combination of rope-assisted proprioceptive neuromuscular facilitation(PNF)training and rope-assisted brain-computer interface(BCI)training on upper limb function in stroke patients with hemiplegia. Methods From March,2022 to February,2023,96 inpatients with stroke hemiplegia from the Second Affiliated Hospital of Guangxi Medical University were randomly divided into conventional group(n=32),PNF group(n=32)and combined group(n=32).All the groups received routine rehabilitation treatment.The conventional group re-ceived upper limb PNF training,the PNF group received upper limb rope-assisted PNF training,and the com-bined group received both upper limb rope-assisted PNF training and upper limb rope-assisted BCI training,for four weeks.They were assessed with Functiongal Test for the Hemiplegic Upper Extremity-Hong Kong version(FTHUE-HK),Fugl-Meyer Assessment-Upper Extremities(FMA-UE)and modified Barthel Index(MBI)before and after treatment. Results The intra-group effect(F>341.219,P<0.001),inter-group effect(F>21.705,P<0.001)and interaction effect(F>3.171,P<0.05)were significant in the scores of FTHUE-HK and MBI.The intra-group effect(F=520.472,P<0.001)and inter-group effect(F=41.939,P<0.001)were significant in the scores of FMA-UE,and the interaction effect was not(P>0.05).After treatment,the FTHUE-HK,FMA-UE and MBI scores were the best in the combined group(P<0.05). Conclusion The combination of rope-assisted PNF training with rope-assisted BCI device training could further improve the motor function of the upper limbs in stroke patients with hemiplegia,and enhance their activities of daily liv-ing.

OBJECTIVE: To investigate the effect of inhibitor of growth protein-2 (Ing2) silencing on angiotensin Ⅱ (AngⅡ)-induced cardiac remodeling in mice and explore the underlying mechanism. METHODS: An adenoviral vector carrying Ing2 shRNA or empty adenoviral vector was injected into the tail vein of mice, followed 48 h later by infusion of 1000 ng · kg^-1 · min^-1 Ang Ⅱ or saline using a mini-osmotic pump for 42 consecutive days. Transthoracic echocardiography was used to assess cardiac geometry and function and the level of cardiac hypertrophy in the mice. Masson and WGA staining were used to detect myocardial fibrosis and cross-sectional area of cardiomyocytes, and myocardial cell apoptosis was detected with TUNEL assay. Western blotting was performed to detect myocardial expressions of cleaved caspase 3, ING2, collagen Ⅰ, Ac-p53(Lys382) and p-p53 (Ser15); Ing2 mRNA expression was detected using real-time PCR. Mitochondrial biogenesis, as measured by mitochondrial ROS content, ATP content, citrate synthase activity and calcium storage, was determined using commercial assay kits. RESULTS: The expression levels of Ing2 mRNA and protein were significantly higher in the mice with chronic Ang Ⅱ infusion than in saline-infused mice. Chronic infusion of AngⅡ significantly increased the left ventricular end-systolic diameter (LVESD) and left ventricular end-diastolic diameter (LVEDD) and reduced left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) in the mice. Ing2 silencing obviously alleviated AngⅡ-induced cardiac function decline, as shown by decreased LVEDD and LVESD and increased LVEF and LVFS, improved myocardial mitochondrial damage and myocardial hypertrophy and fibrosis, and inhibited cardiomyocyte apoptosis. Chronic AngⅡ infusion significantly increased myocardial expression levels of Ac-p53(Lys382) and p-p53(Ser15) in the mice, and Ing2 silencing prior to AngⅡ infusion lessened AngⅡ- induced increase of Ac-p53(Lys382) without affecting p53 (ser15) expression. CONCLUSION Ing2 silencing can inhibit AngⅡ-induced cardiac remodeling and dysfunction in mice by reducing p53 acetylation.

ObjectiveTo investigate the effect of combination of proprioceptive neuromuscular facilitation (PNF) rope training and repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function of stroke patients with hemiplegia. MethodsFrom March, 2021 to February, 2022, 90 stroke inpatients with hemiplegia in the Department of Rehabilitation Medicine, the Second Affiliated Hospital of Guangxi Medical University were divided into control group (n = 30), rope group (n = 30) and combination group (n = 30) randomly. All the groups received routine rehabilitation, while the control group received routine PNF training, the rope group received PNF rope training, and the combination group received PNF rope training and rTMS, for four weeks. They were assessed with Functional Test for the Hemiplegic Upper Extremity-Hong Kong version (FTHUE-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsThe scores of FTHUE-HK, FMA-UE and MBI increased in all the three groups after treatment (t > 2.167, P < 0.05), and they were more in the combination group than in the rope group (P < 0.05), and in the rope group than in the control group (P < 0.05). ConclusionThe combination of PNF rope training and rTMS is more effective on motor function of upper limbs of stroke patients with hemiplegia than PNF training alone.

Objective:To investigate the causes, diagnosis, treatment and prognosis of children with spinal cord injury without radiologic abnormality caused by non-severe violence, and to raise the awareness of spinal cord injury in children.Methods:Retrospective analysis was performed on the age of onset, injury mechanism, main clinical symptoms and occurrence time, treatment process and recovery of children with spinal cord injury without radiologic abnormality caused by non-severe violence. The children were admitted to our hospital from August 2015 to September 2020. Abnormal findings in spinal cord MRI in acute stage were analyzed, and long-term prognosis was followed up by telephone. The degree of spinal cord injury was determined according to the criteria established by the American Spinal Cord Injury Association.Results:Of six patients, three boys and three girls, aged from 16 months to 8 years old.Injury mechanism: fall on the bed, a sudden fall in standing position, fall while jumping in sports.All of the symptoms appeared immediately after trauma, such as limb weakness, pain, unable to walk, urination disorders.Treatment process: spinal immobilization, methylprednisolone pulse therapy[20 mg/(kg·d)], alleviat edema and protect the nerve system, necessary symptomatic treatment including urethral catheterization, the use of antibiotics, timely rehabilitation treatment.No fracture or dislocation was found in all six patients by spinal cord radiometric examination, and MRI of spinal cord indicated abnormal signals of thoracic cord or below. The recovery sequence of spinal cord function: urination function recovery, pain from lower limbs relief, lower limbs weakness improvement.By the time of follow-up by telephone, the course of disease was 1 to 5 years. Urine fecal incontinence was found in one patient, and his muscle strength of both lower extremities belong to grade Ⅰ, atrophic changes were found in spinal cord MRI.The remaining five patients were able to walk independently, complained of leg pain during long distance walking, mild varus or valgus, and no obvious abnormality in spinal cord MRI.Conclusion:In daily activities, except bend down in dancing, falling on the sacral tail is easy to cause spinal cord injury without fracture and dislocation in children. The damaged spinal cord function often cannot recover thoroughly, and even cannot recover. It is advisable to identify early, formulate comprehensive treatment measures in time, strive to improve the prognosis.

As a sensor of cytosolic DNA, the role of cyclic GMP-AMP synthase (cGAS) in innate immune response is well established, yet how its functions in different biological conditions remain to be elucidated. Here, we identify cGAS as an essential regulator in inhibiting mitotic DNA double-strand break (DSB) repair and protecting short telomeres from end-to-end fusion independent of the canonical cGAS-STING pathway. cGAS associates with telomeric/subtelomeric DNA during mitosis when TRF1/TRF2/POT1 are deficient on telomeres. Depletion of cGAS leads to mitotic chromosome end-to-end fusions predominantly occurring between short telomeres. Mechanistically, cGAS interacts with CDK1 and positions them to chromosome ends. Thus, CDK1 inhibits mitotic non-homologous end joining (NHEJ) by blocking the recruitment of RNF8. cGAS-deficient human primary cells are defective in entering replicative senescence and display chromosome end-to-end fusions, genome instability and prolonged growth arrest. Altogether, cGAS safeguards genome stability by controlling mitotic DSB repair to inhibit mitotic chromosome end-to-end fusions, thus facilitating replicative senescence.

Objective:To investigate whether children with benign childhood epilepsy with centrotemporal spikes (BECT) still have attention network damage and its correlative factors after complete remission.Methods:Thirty BECT patients over 16 years old and without seizures over two years (BECT group; 21 males, nine females, median age 17 years) in the Department of Neurology, Provincial Children′s Hospital Affiliated to Anhui Medical University from January 1, 2009 to December 31, 2010 and 42 healthy controls (control group; 30 males, 12 females, median age 17 years) from the First Affiliated Hospital of Anhui Medical University were tested by the attention network test tool.Results:There was not statistically significant difference in the accuracy rate and total reaction time of attention network test between the BECT group and the control group [97.0% (95.0%, 99.0%) vs 98.0% (95.5%, 98.0%), Z=-0.437, P=0.662; 587.50 (523.50, 668.75) ms vs 610.00 (584.25, 631.75) ms, Z=-0.320, P=0.749; respectively]. And there was not statistically significant difference in the efficiency of the alert network, directional network, and executive control network in the BECT group compared with the control group [(46.13±24.97) ms vs (48.52±27.65) ms, t=-0.376, P=0.708; (32.23±18.12) ms vs (33.21±19.68) ms, t=-0.215, P=0.830; (124.50±39.87) ms vs (117.60±50.13) ms, t=0.626, P=0.533; respectively]. The accuracy of attention network test was positively correlated with the age of onset ( b=0.925, P=0.012), and was negatively correlated with the total number of seizures ( b=-0.853, P=0.025). Conclusion:Although the accuracy of attention network test in BECT patients after remission was correlated with age of onset and total number of seizures, BECT patients had no attention network damage after complete remission compared with healthy controls.

The control group patients received conventional perioperative management, and the observation group underwent FTS-CNP management mode, recording postoperative feeding time, postoperative activity time, hospitalization time, complication rate, and physical and mental health score values.Results:The eating time, postoperative activity time, length of stay, and complication rate in the observation group were (0.52 ± 0.15)days, (1.17 ± 0.38)days, (5.43 ± 0.90)days, and 0, and the control group were (1.54 ± 0.24)days, (2.19 ± 0.58)days, (7.80 ± 0.80)days, and 40%(12/30). There was a statistical difference between the two groups ( t value was 11.40, 4.64, 6.23, χ2 value was 13.33, P <0.05). Physiological and mental health of the observation group after cesarean section The scores were 152.21 ± 5.15 and 127.23 ± 2.38, and the control group was 115.14 ± 2.24 and 101.92 ± 2.58. There was also a statistical difference between the two groups ( t value was 11.21, 14.04, P<0.05). Conclusions:FTS group management mode can provide obstetrics perioperative patients with quality and efficient services, which is hopeful to achieve good social and economic benefits.

Objective:To compare and observe the changes in choroidal thickness between healthy pregnant women and healthy non-pregnant women.Methods:A prospective clinical study. From January 2019 to August 2019, healthy pregnant women (pregnant women group) and healthy non-pregnant women age-matched were enrolled during the same period (the normal group) in the obstetrics of Zhuji People's Hospital. All patients were enrolled with their right eyes. Frequency-domain OCT-enhanced depth imaging technology was used to measure the subfoveal macular and 1000 μm above, below, nasal, and temporal choroidal thickness and foveal retinal thickness (CMT). The choroidal thickness and CMT of the pregnant women group and the normal group were compared by t test, and the choroidal thickness and CMT of the normal group and the eyes of different gestational weeks were compared by one-way analysis of variance. Results:The pregnant women group and the normal group included 161 patients (161 eyes) and 40 patients (40 eyes). According to the different gestational weeks, the pregnant women were divided into the first trimester group, the second trimester group, and the third trimester group, with 47 patients (47 eyes), 66 patients (66 eyes), and 48 patients (48 eyes) respectively. There was no significant difference in age, axial length, intraocular pressure, and CMT between the different gestational week groups and the normal group ( F=1.433, 1.558, 0.416, 2.288; P>0.05). The subfoveal choroidal thickness (SFCT) of the pregnant women group and normal group were 317.7±73.9 μm and 279.7±44.1 μm, respectively, and the difference was statistically significant ( t=3.113, P=0.002). Compared with the normal group, the choroid at the upper, lower, nasal, and temporal sides of the pregnant group 1000 μm from the fovea was thickened. The difference between the upper, nasal and temporal sides was statistically significant ( t=2.699, 3.474, 2.595; P<0.05). The SFCT of the eyes in the first trimester group, the middle group, and the late group were 305.8±72.3, 327.7±69.8, 315.8±80.5 μm, respectively. Compared with the normal group, the difference was statistically significant ( F=4.180, P=0.007). Pairwise comparison between the two groups, the second trimester group was significantly different from the normal group ( P=0.003). There was no significant difference among the first trimester group、the third trimester group and the other groups ( P>0.05). Conclusion:The choroidal thickness of pregnant women is thicker than normal, and the choroidal thickness in the second trimester reaches the maximum value; while the macular CMT during pregnancy has no significant change.

Objective:To accurately estimate the health burden and corresponding economic loss attributed to PM 2.5 pollution in the Beijing-Tianjin-Hebei (BTH) area in China in 2015. Method:By using satellite-retrieved PM 2.5 concentration data and population data provided by NASA (the spatial resolution was 1 km×1 km), this study estimated excess mortality attributed to long-term PM 2.5 exposure in BTH area in 2015 based on Global Exposure Mortality Model (GEMM). Besides, Value of Statistic Life (VSL) method was used to evaluate the corresponding health economic loss. Result:In BTH area, the population-weighted average PM 2.5 concentration during 2012-2014 was 46.25 μg/m 3, and 56.6% of total population lived in the area where annual average PM 2.5 concentration exceeded Grade Ⅱ of National Ambient Air Quality Standard in China (35 μg/m 3); The PM 2.5-related premature deaths amounted to 193.8 thousand (95 %CI: 140.9 thousand-233.3 thousand), Beijing, Tianjin, Baoding, Shijiazhuang, and Handan were the top five cities with high incidences of PM 2.5-related premature deaths; The corresponding health economic loss was about 35.934 billion (95 %CI: 26.099 billion - 43.255 billion) RMB, accounting for 0.70% (95 %CI: 0.51%-0.85%) of the area’s GDP in 2015, Beijing, Tianjin, Baoding, Shijiazhuang, and Cangzhou were the top five cities with high health economic loss. Conclusions:PM 2.5 pollution has caused severe disease and economic burden in BTH area. Its spatial distribution suggested that it is particularly necessary to develop the air pollution prevention and control policies for key cities.
