ABSTRACT
PURPOSE@#The long-term situation of children with spinal cord injury (SCI) was investigated, and suggestions for helping them better return to the society were provided.@*METHODS@#SCI patients less than 18 years old hospitalized in Beijing Boai Hospital from January 2011 to December 2020 were retrospectively analyzed. Information including motor function, complications, characteristic changes, self-care abilities, school attendance and social participation were collected by telephone interview and electronic questionnaire. All the answers were statistically analyzed.@*RESULTS@#A total of 86 cases were enrolled, 77 girls and 9 boys, with a median injury age of 6 years and 2 months. The follow-up time was 3-130 months. The main cause of trauma in these children was sport injury (66.3%), the thoracic spinal cord was involved the most (91.9%), and complete SCIs accounted for the majority (76.7%). In terms of complications, children with complete SCIs were more likely to have urinary incontinence, constipation and characteristic changes (p < 0.05); whereas the incomplete SCIs often have spasticity (p < 0.05). As to the daily living abilities, children with incomplete lumbar SCIs were more capable to accomplish personal hygiene, transfer, and bathing independently than those with complete injuries, or cervical/thoracic SCIs, respectively (p < 0.05). Moreover, children older than 9 years care more able to dress and transfer independently than the youngers (p < 0.05). Wheelchair users accounted for 84.9% and more than half of them were able to propel wheelchair independently, and those who move passively in wheelchairs were mostly introverted kids (p < 0.05). Almost all (93.8%) children with incomplete injuries were able to walk independently. Most (79.1%) children continued to attending school, and 41.9% participated in interest classes. Unfortunately, 67.4% of the children spent less time playing with their peers than before the injury.@*CONCLUSION@#SCIs impair physical structures and function of children, affect their independence in daily living, and restrict school attendance and social interaction. Comprehensive rehabilitation after injury is a systematic work. Medical staff and caregivers should not only pay attention to neurological function, but also help them improve self-care abilities. It is also important to balance rehabilitation training and school work and social participation.

Objective:To explore the effect of combining hyperbaric oxygen (HBO) therapy with cognition training for persons with vascular cognitive impairment (VCI).Methods:Forty-two persons with VCI were randomly divided into a control group of 19 and a research group of 23. In addition to basic treatment, the control group was given hyperbaric oxygen therapy once a day, 5 days per week for 4 weeks, while the research group received cognition training along with the hyperbaric oxygen therapy. Each person′s cognition was assessed using the Simple Mental Status Scale (MMSE) before and after the four-week treatment. Meanwhile, 3ml of venous blood was collected before eating in the morning to test the plasma levels of Klotho protein and homocysteine using enzyme-linked immunosorbent assays.Results:After the treatment the average MMSE score had improved significantly in both group, with the improvement in the research group′s average significantly greater than that in the control group. The average plasma levels of Klotho protein and homocysteine had also improved significantly more in the research group. In the control group, the only significant improvement was in the average homocysteine level.Conclusions:Hyperbaric oxygen therapy can be an effective supplement to cognition training for persons with vascular cognitive impairment.
ABSTRACT
Objective:To investigate the effect of combining aerobic exercise with hyperbaric oxygen therapy on the cognition and oxidative stress of patients with post-stroke cognitive impairment (PSCI).Methods:Forty-five PSCI patients were divided randomly into a hyperbaric oxygen therapy (HBO) group (of 21) and a combination group (of 24). Both groups received HBO therapy, but the combination group also performed 30min of aerobic exercise using a cycle ergometer 5 times a week for 8 weeks. The HBO therapy involved 20min for pressurization, 20min of decompression, 60min of pressurized oxygen inhalation and 10min of air inhalation. The treatment pressure was 0.2MPa (2.0ATA). Before and after the intervention, cognitive functioning was measured using the mini-mental state examination (MMSE) and the Montreal cognitive assement (MoCA). The Barthel index quantified ability in the activities of daily living. Serum glutathione (GSH) and malondialdehyde (MDA) were measured spectrophotometrically.Results:The average MMSE scores of both groups had improved significantly after the treatment, with significantly better improvement in the combination group. After the treatment, the average MoCA score of the combination group had improved significantly while that of the HBO group had not. The average Barthel index scores of both groups improved significantly and there was no significant difference between them after the treatment. The average serum GSH increased after the treatment in the combination group, and the increase was weakly positively correlated with the increase in MMSE scores. The average MDA content of the HBO group decreased after the treatment, and the decrease was positively correlated to the increase in the MMSE scores, but again weakly.Conclusions:Aerobic exercise combined with hyperbaric oxygen therapy can effectively improve cognition among PSCI patients. Increases in serum GSH and decreases in serum MDA are weakly positively correlated with cognitive functioning.
ABSTRACT
Breast cancer is the most common cancer in women. At present, the in vivo model and traditional cell culture are mainly used in breast cancer researches. However, as high as 90% clinical trials are failed for drugs explored by the above two methods, due to the inherent species differences between humans and animals, as well as the differences in the tissue structure between organs and cells. Therefore, organoid three-dimensional culture is emerging. As a new tumor research model, organoid, a three-dimensional cell complex with spatial structure, has broad application prospects, such as precision medicine, organ transplantation, establishment of refractory disease model, gene therapy and drug research and development. Therefore, organoid is considered as one of the ideal carriers for life science research in the future. Breast cancer, a heterogeneous disease with complex phenotypes, has a low survival rate. Breast cancer organoid can reproduce many key features of human breast cancer, thus, the construction of organoid biological library of breast cancer will provide a new platform for studying the occurrence, development, metastasis and drug resistance mechanism of breast cancer. In this review, we systematically introduce the culture conditions of organoids and their application in breast cancer related research, and the application prospect of organoids.

ABSTRACT
Aim To determine the distribution of succinylcholine chloride (Suc) at toxic dose in rats by establishing UHPLC-MS/MS analysis. Methods The rats were subcutaneously injected with three doses of Suc, and 4 h later, rat serum and major organs were taken for acetonitrile protein precipitation and purified by solid phase extraction with WCX column. Luna NH2 column (2 mm × 100 mm, 3 μm) was used for chromatography. The mobile phase was 0. 1% formic acid-acetonitrile isoelution. Mass spectrometry was carried outwith positive ion scanning multi-reaction monitoring mode (MRM). Qualitative and quantitative analysis was conducted on the ion pairs of Suc (m/z 145. 1→93.3, m/z 145.1→115.4). Results The detection limit of Suc was 0.01 μg · L-1, the recovery rate was 89. 5% ∼ 95. 4%, and the intraday and mtraday RSD was less than 15%. Except in the untreated rat, Suc was detected in the serum, heart, liver, kidney and other major organs from Sue-administered rats, and Suc content in the kidney was the highest among organs. Conclusions Sucat poisoning dose is distributed in the serum, heart, liver, kidney and other tissues. The content in the kidney is the highest; UHPLC-MS/ MS analysis is an effective and reliable method for detecting the drug content in Sue-poisoned rats.
ABSTRACT
OBJECTIVE: To discuss the clinical significance of cesarean scar pregnancy with expectatant treatment.METHODS: Collect 21 cases of CSP between 2012 and 2017 in the Third Affiliated Hospital of Guangzhou Medical University.Group A had 8 cases who were pregnant again after intervention treatment,and group B had 13 cases who insisted on expecting treatment.We summarized clinical indexes of both groups,such as preserving uterus,bladder rupture,admission to ICU,blood transfusion,placenta implantation,etc. in order to further study the significance of expecting treatment for CSP.RESULTS: All of group A were pregnant again after intervention treatment,of whom 1 was CSP again and hysterectomy was performed at 15 weeks due to placenta implantation,while another 7 were uterine pregnancy,of whom 3 were term birth and had no placenta implantation,and another 4 were terminated in response to the requirements of patients,of whom 1 was treated with drug abortion and 3 underwent dilatation and curettage.Uterus was preserved in the 7 women,and there was no bladder rupture,no admission to ICU,no blood transfusion,and no placenta implantation.Among the 13 cases in group B, 6 cases underwent cesarean section during third trimester,including 3 cases of premature delivery and 3 cases of delivery at 37 weeks.5 cases were pregnant to second trimester,containing 4 cases received hysterectomy and 1 case suffered subtotal hysterectomy.2 cases were pregnant to first pregnancy, including 1 case of abdominal nidus resection, 1 case of ultrasound-guided dilation and curettage;Among the13 patients, 4 cases underwent bladder rupture, 4 cases lost uterus, 5 cases were admitted to the ICU, and 10 cases required blood transfusion.Placental implantation occurred in 11 cases who were pregnant to second and third trimester.CONCLUSION: Most of CSP with expecting treatment will develop into placenta implantation inevitably in the late stage of pregnancy.The patients with CSP can be pregnant again after early intervention and have extremely low possibility of a second CSP.

ABSTRACT
Objective@#To analyze the association between maternal bisphenol A exposure during early pregnancy and sleep problems among preschool children.@*Methods@#Research subjects were from one of the sub-cohorts(Ma'anshan Cohort) of the China-Anhui Birth Cohort Study (C-ABCS) in Ma'anshan city. The basic situation of pregnant women and sleep information of preschool children were investigated. We selected preschool children whose mother's maternal serum bisphenol A concentrations of the first trimester had been already detected between December 2012 to Januray 2014. 1 259 pairs of mothers and children were included. The concentrations of bisphenol A exposure during early pregnancy were divided into low, medium and high exposure groups according to 25th percentile (P25) and 75th percentile (P75) levels. Multivariate multinomial logistic regression model was used to analyze the association between maternal bisphenol A exposure during early pregnancy and sleep-related problems in preschool children.@*Results@#The P50 (P25-P75) of serum bisphenol A exposure level during early pregnancy was 0.231 (0.106-0.512) ng/ml. The sleep-related problems scores of 1 259 preschool children were (16.43±3.82) points. The occasional sleep-related problems were detected about 47.8% (602 cases) and frequent sleep-related problems were detected about 18.3% (230 cases). After the adjustment of the confounding factors such as children's gender, age, BMI, sleep position (lying down, sleeping on one's back), the length of time to sleep and the length of sleep at night, in comparison with bisphenol A low exposure group, the OR (95%CI) value of preschool children with occasional sleep-related problems in maternal bisphenol A high exposure group during early pregnancy was 1.44 (1.01-2.06). After the gender stratification, the results showed that in comparison with bisphenol A low exposure group, the OR (95%CI) value of preschool girls with occasional sleep-related problems in maternal bisphenol A medium and high exposure group during early pregnancy were 1.61 (1.05-2.46) and 2.40 (1.42-4.04), respectively. The OR (95%CI) value of preschool girls with frequent sleep-related problems in maternal bisphenol A high exposure group during early pregnancy was 2.64 (1.34-5.17). However, in boys, there was no statistically significant association between maternal bisphenol A exposure during early pregnancy and sleep-related problems (P>0.05).@*Conclusion@#Maternal bisphenol A exposure during early pregnancy might be related to sleep-related problems in preschool children.
ABSTRACT
Objective@#To investigate the association between the internal exposure levels of phthalic acid esters (PAEs) and executive function (EF) of preschool children.@*Methods@#Between October 2008 and October 2010, pregnant women who accepted pregnancy health care services in four municipal medical and health institutions in Ma'anshan city, Anhui Province, were recruited as study objects. A total of 5 084 pregnant women and 4 669 singleton live births were enrolled in this cohort. The follow-up study was conducted from April 2014 to April 2015. A total of 3 725 data-completed preschool children aged 3 to 6 years older entered in this study. The method of analysis seven metabolites of phthalates in urine was high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and divided objects into low (P0-P24), medium (P25-P74) and high (P75-P100) groups according to their exposure concentrations. To investigate the executive function of preschool children, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the etiology association between the phthalate metabolites levels and preschool children's executive function.@*Results@#In this study, 53.6% (1 997/3 725) of preschoolers were boys, children's age was (51.5±5.6) months. The detection rates of seven phthalate esters were: mono-n-methyl phthalate (MMP) was 99.89% (3 721/3 725); mono-ethyl phthalate (MEP) was 99.97% (3 724/3 725); mono-benzyl phthalate (MBzP) was 69.10% (2 574/3 725); mono-butyl phthalate (MBP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono- (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were 100.00% and mono-ethylhexyl phthalate (MEHP) was 99.95% (3 723/3 725). The median concentrations of the seven phthalate metabolites were: 17.71, 15.36, 0.07, 155.24, 10.73, 14.67, 3.59 µg/L, respectively. The median concentrations corrected by urinary creatinine were 29.65, 26.65, 0.12, 257.73, 17.94, 24.80, 6.27 µg/g Cr, respectively. The P25 and P75 concentration of the total PAEs metabolites corrected by urinary creatinine were 1.20 µmol/g Cr and 3.04 µmol/g Cr. After adjusted the relevant demographic information: children sex, children age in month, maternal age, parental education levels, household exposure to secondhand smoke and whether the child is the only child as confounds, multivariate logistic regression model showed that the risk of inhibitory self-control index (ISCI) dysplasia in MEHHP high concentration group and MEOHP high concentration group were 1.71 and 1.54 times (OR=1.71, 95% CI: 1.11-2.62; OR=1.54, 95% CI: 1.01-2.34) than in low concentration group. The risk of ISCI dysplasia in total PAEs metabolites high concentration group was 1.55 times (OR=1.55, 95% CI: 1.00-2.38) than in low concentration group.@*Conclusion@#Phthalates exposure may damage the executive function of preschool children.

ABSTRACT
Objective To investigate the effect of cysteine protease inhibitor derived from S chistosoma japonicum(SjCys-tatin)on dextran sodium sulfate(DSS)-induced acute ulcerative colitis in mice.Methods Eighteen C57BL/6 mice were ran-domly divided into three groups:a control group treated with PBS(Group A),a DSS-induced-colitis group treated with PBS(Group B),and a DSS-induced-colitis group treated with SjCystatin(Group C).Colitis was induced in mice by giving 3％DSS orally for 7 days.During this period,the mice were daily injected with 10μg of SjCystatin or PBS only as a control intraperitone-ally.The mice were monitored daily for their clinical manifestations and given scores based on disease activity index(DAI).The severity of colonic inflammation was monitored by the macroscopic score and pathological change.The cytokine profile including TNF-α,IL-4,IL-6 and IL-10 in the supernatants of colon homogenate was detected by ELISA.Results Compared with Group A(0.50 ± 0.28),the DAI score increased significantly in Group B(9.30 ± 1.30)(F=86.86,P<0.01),with remarkable path-ological damages seen in colon tissues.and the levels of TNF-α and IL-6 were(321.33±67.01)and(403.58 ±180.51)pg/mL.The DAI score significantly reduced in Group C(6.67±1.57)as compared to Group B(F=86.86,P<0.01),with improve-ments in the macroscopic and microscopic pathology in mouse colon specimens.As compared to Group B,the levels of TNF-α [(188.14 ± 40.14)pg/mL] and IL-6 [(209.71 ± 48.47)pg/mL] significantly decreased(F=17.46 and 9.89,both P<0.01).Con-clusion SjCystatin has a significantly inhibitory effect for alleviating DSS-induced acute ulcerative colitis in C57BL/6 mice.
ABSTRACT
· Endoplasmic reticulum (ER) is a place where it folds and synthesizes the proteins.ER stress was induced when a variety of physiological and pathological factors happened,under which the protein misfolding occurred,the unfolded protein accumulated and the calcium ion imbalanced in the ER.The ER of high-glucose environment can change the protein redox state and produce reactive oxygen species,which affects the ER channel function and chaperone protein buffer;meanwhile changes the balance of calcium ions;finally induces the formation of ER stress.More and more studies have confirmed that ER stress in high glucose environment can cause a variety of ophthalmic diseases.So we review the recent articles about ER stress of high glucose environment and its related ophthalmic diseases.

<p><b>OBJECTIVE</b>To observe the effect of Schistosoma japonicum cysteine protease inhibitor (rSjCystatin) for treatment of lipopolysaccharide (LPS)-induced sepsis in mice.</p><p><b>METHODS</b>After a week of adaptive feeding, 54 BALB/c mice were randomly divided into normal control group (group A), sepsis group (group B), and rSjCystatin intervention group (group C). The mice in group A received an intraperitoneal injection of PBS (100 µL), and those in groups B and C were injected with PBS (100 µL) containing LPS (10 mg/kg); the mice in group C were also intraperitoneally injected with 25 µg sjCystatin in 100 µL PBS 30 min after LPS injection. From each group, 10 mice were randomly selected 24 h after PBS or LPS injection for detecting serum levels of TNF-α, IL-6, and IL-10 using ELISA and the levels of ALT, AST, BUN, and Cr using automatic biochemical analyzer; the pathological changes in the liver, lung and kidney were observed with HE staining. The remaining 8 mice in each group were used for observing the changes in the general condition and the 72-h survival.</p><p><b>RESULTS</b>The 72-h survival rates of the mice was 100% in group A, 0 in group B, and 36% in group C, showing a significant difference among the 3 groups (P<0.05). Compared with those in group A, the mice in group B exhibited obvious liver, lung, and renal pathologies with increased levels of ALT, AST, BUN, Cr, IL-6, and TNF-α (P<0.05). Treatment with sjCystatin significantly lessened LPS-induced organ pathologies, lowered the levels of liver and renal functional indexes and the pro-inflammatory cytokines, and increased the serum level of IL-10 in the mice (P<0.05).</p><p><b>CONCLUSION</b>SjCystatin can produce a significant therapeutic effect on sepsis induced by LPS in mice.</p>
