RESUMO

Objective:To compare the efficacy of femoral neck system (FNS) and cannulated compression screw (CCS) in the treatment of femoral neck fracture in the young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 91 patients with femoral neck fracture admitted to Fuzhou Second Hospital from July 2020 to December 2021, including 52 males and 39 females; aged 23-65 years [(48.9±10.3)years]. Garden classification of the fracture found that 31 patients were with type I, 9 with type II, 12 with type III and 39 with type IV. Pauwels classification of the fracture found that 7 patients were with type I, 33 with type II and 51 with type III. A total of 53 patients were treated with FNS fixation (FNS group) and 38 patients with CCS fixation (CCS group). The operation time, intraoperative blood loss, Haidukewych fracture reduction quality, hospitalization time, Barthel index, fracture healing time, and weight-bearing time were compared between the two groups. The hip function was assessed by Harris hip score in both groups at postoperative 3 months, 6 months and 1 year and at the final follow-up. The incidences of postoperative complication and secondary surgery were also compared between the two groups.Results:All the patients were followed up for 15-31 months [(22.2±5.5)months]. There were no significant differences in the operation time, Haidukewych fracture reduction quality, hospitalization time, or Barthel index (all P>0.05). The intraoperative blood loss in the FNS group was 50.0(20.0,85.0)ml, which was more than that in the CCS group [20.0(10.0,50.0)ml] ( P<0.01). The fracture healing time, partial weight-bearing time, and full weight-bearing time in the FNS group [4.0(3.0,5.0)months, 3.0(2.0,3.0)months, 5.0(4.5,6.0)months] were shorter than those in the CCS group [6.0(5.0,7.0)months, 3.0(2.8,4.0)months, 6.0(6.0,7.0)months] (all P<0.01). The Harris hip score at postoperative 3 months, 6 months and 1 year and at the final follow-up were 74.0(71.0,77.0)points, 87.0(84.0,88.5)points, 91.0(88.0,95.0)points, and 94.0(91.0,96.0)points in the FNS group, significantly higher than those in the CCS group [73.0(70.0,74.0)points, 82.5(79.8,87.0)points, 88.0(83.5,91.0)points, 89.0(84.0,93.0)points] (all P<0.05 or 0.01). There were no statistically significant differences in the incidences of postoperative complication or secondary surgery between the two groups (all P>0.05). Conclusion:Compared with CCS, FNS can shorten fracture healing time, allow patients to carry full weight as soon as possible, and significantly improve hip function in the treatment of middle-aged and young adults with femoral neck fracture, although there is more intraoperative blood loss.

RESUMO

Objective@#To develop a native adaptive behavior scale for children with autism spectrum disorder(ASD) and to explore its reliability and validity.@*Methods@#Items of ASD adaptive behavior rating scale were selected based on the scale development theory, ASD knowledge and adaptive behavior concept through preliminary survey and statistical, and 301 ASD children aged 2 to 12 from hospitals in Guangzhou, Huizhou, Shenzhen who met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition were selected, data was analyzed by the item analysis.@*Results@#After item analysis and exploratory factor analysis, the final version of the scale contains 58 items, and 64.24% of the total variation could be explained by 6 factors; The Cronbach’s α coefficient of the full scale was 0.98, and the coefficient value of dimen sional factors were 0.94,0.93,0.91,0.95,0.88,0.94. The test-test reliability r of full scale was 0.86, the r of the factor were 0.88,0.81,0.81,0.87,0.88,0.79. The criterion-related validity r with the ABAS-Ⅱ scale was -0.77, the criterion-related validity r with the CARS scale was 0.64.@*Conclusion@#The ASD Child Adaptive Behavior Scale showed good reliability and validity, and could be used widely.

RESUMO

Objective To explore the association of anti-mullerian hormone(AMH)in seminal plasma and serum with sperm counts and energy for male.Methods For 215 cases of healthy male selected from our reproductive clinic,with women′s reason for infertility,seminal plasma and serum AMH were detected,as semen parameters(sperm density,living rate,vitality and malformation rate),6 items of serum sex hormone.In seminal plasma and serum AMH respectively as the dependent variable,using multiple line-ar regression model to explore its quantitative relation with semen parameters and sex hormone levels.Results 215 cases were en-rolled,aged 34.28±5.70 years,while the median of the seminal plasma AMH was 0.47,quartile 0.05-3.09 pmol/ejaculation.The median of the serum AMH was 53.07,quartile 32.32 -72.20 pmol/L.Through multiple linear regression analysis,after adjusted by age and BMI,the seminal plasma of AMH and total number of sperm,sperm concentration,dynamic motility,total sperm activi-ty,serum inhibin B were positively correlated(P 0.05);Serum AMH negatively correlated with serum FSH,with serum inhibin B positively(P 0.05).Conclu-sion The seminal plasma of AMH were positively correlated with sperm concentration,sperm counts,sperm vitality,with the asso-ciation for serum AMH not yet found.

RESUMO

BACKGROUND: Previous studies have verified that under normal culture of neural stem cells (NSCs), folic acid can accelerate proliferation of NSCs by phosphorylation of mitogen activated protein kinase path activation ERK1/2. OBJECTIVE: To investigate the effect of folic acid on NSC extracellular signal regulatory protein kinase pERK1/2 under hypoxic condition. METHODS: NSCs from Neonatal rats were cultured in vitro by serum-free culture method, and incubated in a flask at 1×10~8/L. Except normal control group, self-made hypoxia equipment was used in the hypoxia model, folic acid deficiency and folic acid supplemented groups at day 3. At 37 ℃, hypoxia culture was conducted in the thermostat for 6 hours. The contents of folic acid were 4 mg/L, 4 mg/L, 0.65 mg/L, 8 mg/L in the four groups. Cells following 6 days were collected to count the density using trypan blue. RT-PCR was utilized to detect pERK1/2 mRNA expression. Western blot assay was employed to determine pERK1/2 protein expression. RESULTS AND CONCLUSION: Compared with the normal control group, the proliferation of NSCs and the expression of ERK1/2mRNA and pERK1/2 protein were decreased significantly in the hypoxia model group. Compared with the hypoxia model group, the proliferation of NSCs and the expression of ERK1/2mRNA and pERK1/2 protein were increased in the folic acid supplemented group, whereas decreased in the folic acid deficiency group. There were significant differences among groups (P < 0.001). Above-described results verified that folic acid supplementation can activate ERK1/2 phosphorylatin and accelerate proliferation of NSCs under hypoxia condition.

RESUMO

Objective To study the effects of folate(Fol) on proliferation,apoptosis and the antioxidative capacity of the NSCs under hypoxia in vitro.Method The NSCs taken from infant rats brain were cultured by serum-free medium in vitro and divided into four group which were normal control group(NC),hypoxia group(Hyp),Hpy+Fol-D(folate deficient)group and Hpy+Fol group.Except NC group,the other groups were cultured in hypoxia condition for 6 h.The proliferation of NSCs after hypoxia damage was detected by MTT test.The NSCs were collected after being cultured 6 d and then the activity of SOD and GSH-PX was examined.The expression of activated caspase-3 was detected by Western blot.Results Compared with NC group,the proliferation of NSCs and the activity of SOD and GSH-PX decreased significantly after hypoxia,while the expression of activated caspase-3 increased0 The proliferation of NSCs and the activity of SOD and GSH-PX in Hyp group were significantly higher than Hyp+Fol-D group but much lower than Hpy+Fol group(P
