Objective To observe the effect of the long-term low-dose mifepristone on the treatment of hysteromyoma.Methods From March 2016 to December 2016 in Haiyan maternal and child health-care center,120 cases with hysteromyoma were selected as the object study and were given long term oral low-dose mifepristone.The uterus size, follicle stimulating hormone, myoma size, luteinizing hormone, estrogen and endometrium were observed Resultsafter treatment, the patients with uterine fibroids situation improved markedly, and appeared amenorrhea.At the same time, in patients with clinical symptoms were improved to a certain extent, six months after a drug follicle-stimulating hormone, luteinizing hormone and estrogen levels significantly decreased, and there is no other significant side effects.In addition, on the analysis of the effectiveness of the treatment,86 cases were markedly improved,28 cases effective,6 cases ineffective, the total effective rate was 95%.Conclusion Long-term low-dose mifepristone has worked well in the treatment of uterine fibroids, can effectively reduce uterine fibroids, high security, in the process of follow-up of patients, no recurrence no satisfaction related data, the result can't reach this Conclusion , the authors modify please.Is the ideal way of conservative treatment of uterine fibroids, and is worth popularizing in the process of clinical application.

Objective To evaluate the feasibility of virtual touch tissue quantification (VTQ) for the assessment of renal allograft.Methods A total of 72 kidney recipients were examined with conventional ultrasound and VTQ after transpantation.Biopsies were performed in 34 patients,20 patients were with acute rejection (AR),14 with chronic allograft nephropathy (CAN),38 patients as control group.The peak systolic velocity (PSV) and resistance index(RI) were measured on main,infrarenal and arcuate arteries with conventional ultrasound and shear wave velocity (SWV) of the renal cortex was obtained by VTQ.All the data were compared among three groups.Results There were no significant differences of PSV between two groups.An increased RI was presented in the CAN group(P ＜0.05).The mean SWV was (2.67 ± 0.27) m/s,(2.90 ± 0.31)m/s and (2.28 ± 0.24)m/s for AR,CAN and normal group,respectively.There were significant differences of SWV among the three groups (P ＜ 0.05).Conclusions VTQ technique could provide a new method for the assessment of transplanted kidney.

Objective To evaluate the relationship between extracellular signal-regulated kinase (ERK)and ketamine-induced apoptosis in rat hippocampal neurons.Methods Sprague-Dawley rats at 18 days of gestation were anesthetized.The fetal rats were obtained under the sterile condition and decapitated.The hippocampal neurons were isolated and primarily cultured for 5 days,and were seeded in 6-well plates (2 ml/well) or in 96-well plates (100μl/well) at a density of 5 × 105/ml.The cells were randomly divided into 4 groups (n =18 each):control group (group C),fibroblast growth factor (FGF-2,an ERK agonist) group (group F),ketamine group (group K) and FGF-2 + ketamine group (group FK).The cells were cultured in the plain culture medium in group C.FGF-2 50 ng/ml was added to the culture medium in group F.Ketamine was added to the culture medium in group K.FGF-2 50 ng/ml was added to the culture medium at 20 min before ketamine 100 μmol/L was added in group FK.The phosphorylation of ERK in hippocampal neurons was detected by Western blot at 10 min after treatment.At 24 h after treatment,the neuronal apoptosis was detected by Hoechst33342/PI staining,and the cell survival rate was detected by MTT assay.The apoptosis rate was calculated.Results Compared with group C,the phosphorylation of ERK in hippocampal neurons and the cell survival rate was significantly decreased and the apoptosis rate was increased in K and FK groups (P ＜ 0.05).There was no significant difference in the parameters mentioned above between F and C groups (P ＞ 0.05).The phosphorylation of ERK in hippocampal neurons and the cell survival rat was significantly higher and the apoptosis rate was lower in group FK than in group K (P ＜0.05).Conclusion Ketamine induces apoptosis in rat hippocampal neurons by inhibiting activation of ERK in hippocampal neurons.

Bioinformatics is an interdisciplinary science that combines the tools of mathematics, computer science, and biology to clarify and explore the biological implications of large amounts of biological data. With the continuous development of genome sequencing technology, a large number of biological data has been generated, and mining of the biological significance contained in big data has become one of the main tasks that need to be solved urgently. This article summarizes the risk prediction models for hepatocellular carcinoma (HCC) based on feature genes, so as to provide new perspectives for early identification, prognosis, and treatment optimization of HCC.

PURPOSE: To investigate the effects of hyperbaric oxygen (HBO) pretreatment on cognitive decline and neuronal damage in an Alzheimer’s disease (AD) rat model. MATERIALS AND METHODS: Rats were divided into three groups: normal saline (NS), AD, and HBO+AD. In the AD group, amyloid β peptide (Aβ)₁₋₄₀ was injected into the hippocampal CA1 region of the brain. NS rats received NS injection. In the HBO+AD group, rats received 5 days of daily HBO therapy following Aβ₁₋₄₀ injection. Learning and memory capabilities were examined using the Morris water maze task. Neuronal damage and astrocyte activation were evaluated by hematoxylin-eosin staining and immunohistochemistry, respectively. Dendritic spine density was determined by Golgi-Cox staining. Tumor necrosis factor-α, interleukin-1β, and interleukin-10 production was assessed by enzyme-linked immunosorbent assay. Neuron apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling. Protein expression was examined by western blotting. RESULTS: Learning and memory dysfunction was ameliorated in the HBO+AD group, as shown by significantly lower swimming distances and escape latency, compared to the AD group. Lower rates of neuronal damage, astrocyte activation, dendritic spine loss, and hippocampal neuron apoptosis were seen in the HBO+AD than in the AD group. A lower rate of hippocampal p38 mitogen-activated protein kinase (MAPK) phosphorylation was observed in the HBO+AD than in the AD group. CONCLUSION: HBO pretreatment improves cognition and reduces hippocampal damage via p38 MAPK in AD rats.

Objective:To explore the heterogeneity of behavioral problems and cognitive function of three subtypes of attention deficit hyperactivity disorder(ADHD), and to analyze the related factors of cognitive function.Methods:The outpatients with ADHD were evaluated by Wechsler children′s intelligence test (C-WISC), SNAP-Ⅳ parental rating scale (SNAP-Ⅳ), Conners parental symptom questionnaire (PSQ) and 12 online cognitive function tests. The differences of behavioral problems and cognitive function of children with different subtypes of ADHD, and the correlation between their intelligence level, PSQ, SNAP-Ⅳ and cognitive function were compared by SPSS 22.0 software.Results:The results of PSQ questionnaire showed that ADHD-C ((1.11±0.59), (1.59±0.58), (1.62±0.50)) had higher behavior problems, impulse-hyperactivity and hyperactivity index than ADHD-I ((0.64±0.27), (1.01±0.54), (1.09±0.32)) and ADHD-HI ((0.75±0.35), (1.22±0.58), (1.05±0.38)) ( F=9.374, F=7.644, F=15.176, P<0.05), while ADHD-C (2.01±0.55) had higher learning problems than ADHD-I (1.66±0.58) and ADHD-HI (1.16±0.43) ( F=11.709, P<0.05). In terms of cognitive function, there were differences in language understanding ability, digital reasoning ability, sequence relationship and short-term memory ability ( χ2=6.734, 7.192, 7.822, 8.646, all P<0.05) among the three groups of ADHD children. ADHD-HI (4.00(4.00, 5.00), 5.00(4.25, 6.00), 5.00(4.00, 7.00)) had better language understanding ability, digital reasoning ability and sequence relationship than ADHD-I (3.00(2.00, 5.00), 3.00(2.50, 6.00), 4.00(3.00, 5.50)). The short-term memory ability of ADHD-HI (5.00(4.00, 6.00)) and ADHD-C (5.00(4.00, 6.00)) were better than that of ADHD-I (4.00(3.00, 5.00)). The intellectual structure of ADHD children was positively correlated with spatial cognitive ability, sequential relationship, Raven reasoning test, short term memory span and Wisconsin card sorting test ( r=0.25-0.57, all P<0.05). Children′s learning problems and psychosomatic problems were negatively correlated with their digital comprehension ability ( r=-0.26, -0.25, both P<0.05). Conclusion:The behavioral problems and cognitive function of children with different subtypes of ADHD are different and have a certain correlation.
