ObjectiveTo investigate the characteristics of the ambulatory blood pressure of acute cerebral infarction patients in the first 24 hours from onset and to study the relationship between their neurological deficit and characteristics of blood pressure.MethodsBlood pressure in 31 acute cerebral infarction patients (within 24 h) was measured serially during the first 24 hours in hospital with ambulatory blood pressure monitoring. Their neurological deficit was assessed with the National Institutes of Health stroke scale (NIHSS) on the first and the fifth day. Results83.87% nocturnal blood pressures decreased less than 10%. In multiple linear regression analysis, 24 h diastolic blood pressure (DBP) becomes the only and the most important factor to NIHSS on the first day. The patients with improved NIHSS on the fifth day showed lower nocturnal DBP and mean arterial pressure (MAP) than those of patients with unimproved NIHSS.ConclusionNot only the level but also the circadian of ambulatory blood pressure in acute cerebral infarction patients is significantly abnormal, especially for the reduction of nocturnal blood pressure decrease. On the first day, the neuroulogical deficit and blood pressure influence each other. The patients with higher nDBP and nMAP on the first day may be associated with poor early neurological function outcomes.

SUMMARY Rett syndrome (RTT) , an X-linked dominant neurodevelopmental disorder characterized by regression of language, stereotype hand movement and loss of purposeful hand use, is primarily caused by mutation of menthyl-CpG-binding protein 2 ( MECP2 ). The 76 kb human MECP2 is characterized by three sab'ent features; a very large intron 2 (60 kb) , an 8. 5 kb 3'-UTR with highly conserved regions and different polyadenylation sites, and a 40 kb intergenic region separating MECP2 from the nearest upstream gene. There are two isoforms of MeCP2, MeCP2el and MeCP2e2. The differences between the two isoforms, the function of the 3'-UTR and the long-range cis-regulatory sequences in the intergenic region were extensively studied. In contrast to initial report, recent studies show that MeCP2 binds not only to methylated promoters and silence transcription, but also to the sites outside of genes containing only a few of CpG islands. Furthermore, MeCP2 can function as both an activator and a repressor of transcription.

Objective To investigate the immune and pathological mechanism of the effect of monocyte chemotaxis protein -1 on the development of spinal tuberculosis.Methods A total of 1002 patients were enrolled in Tianjin Haihe Hospital from January 2011 to January 2016, which were included in the diagnostic criteria and exclusion criteria.Divided into 332 cases of spinal tuberculosis group(new spine tuberculosis subjects), 334 cases of pulmonary tuberculosis group( new pulmonary tuberculosis subjects), 336 cases of healthy group(healthy subjects), the serum concentration of monocyte chemotactic protein-1 ( MCP-1 ) was detected by enzyme-linked immunosorbent assay ( ELISA ) .To investigate the factors influencing the expression of MCP-1 and to analyze the correlation between serum MCP-1 concentration and spinal tuberculosis.Results Serum MCP-1 concentration in the body with the tuberculosis pathogenicity and sowing was gradually increasing.The concentration of MCP-1 in the spine tuberculosis group was significantly higher than that in thepulmonary tuberculosis group and the healthy group, the difference was statistically significant (P<0.05).There was no significant difference in serum MCP-1 concentrations between male and female patients in spine tuberculosis group , pulmonary tuberculosis group and healthy group.There was no significant difference in serum MCP-1 concentration between children and adults patients in spine tuberculosis group, pulmonary tuberculosis group and healthy group.Conclusion The serum concentration of MCP-1 in Spinal tuberculosis group is higher than pulmonary tuberculosis group and health group, and it shows an upward trend with the spread of tuberculosis.

Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide,particularly in young adults.Conventional imaging modalities such as CT or MRI can show most of the morphological changes of the brain in TBI.PET/CT and PET/MR can acquire both functional and morphological images compared with CT or MRI alone,which might be helpful for the diagnosis,management and prognosis evaluation of TBI.This review summarizes the applications of PET imaging in TBI patients.

Objective To compare the treatment outcome and prognostic factors in patients with advanced cervical cervical cancer between Han and Uygur in Xinjiang district.Methods 204 patients with advanced cervical cancer were retrospectively analyzed.Eighty patients were Han 80 and 124 were Uyghur.100 patients received radiotherapy alone and 49 with concurrent radiochemotherapy,and 55 had brachytherapy followed by surgery.The survival rate was calculated by Kaplan-Meier method and the difference was compared by Logrank test.Multivariate analysis was performed using Cox regression model.Results The follow-up rate was 97.5％.The number of patients with at least 5 years of follow up was 102.The 1-,3-and 5-year overall survival rates in Han and Uygur patients were 81.2％,66.3％,51.4％ and 83.4％,62.8％,49.2％,respectively (x2 =3.21,P =0.273).Univariate analysis showed that parity,geographical distribution,pathological type,clinical stage,lymph node involvement and treatment were prognostic factors for overall survival (x2 =2.35,11.34,7.12,6.73,4.79,13.60,P=0.049,0.029,0.031,0.037,0.041,0.021).Multivariate analysis showed that parity,geographical distribution,pathological type,clinical stage,lymph node involvement and treatment were independent prognostic factors for overall survival (x2 =8.36,24.94,10.69,5.63,9.50,P =0.002,0.001,0.021,0.018,0.031).Conclusions There is no significant difference in overall survival rate of patients with advanced cervical cancer between Han and Uighur.Patients with parity more than or equal to 3 times,advanced clinical stage or adenocarcinoma have poor prognoses.

Objective To investigate the effects of erythropoietin (EPO) on neuron apoptosis and expression of caspase-3 after excitotoxic brain injury induced by ibotenic acid (Ibo) in mice during different developmental stages.Methods A total of 144 healthy KM mice aged 7 d (n =48),21 d (n =48) and 42 d (n =48) were selected,and those of the same age were randomly (random number) divided into 3 groups:sham surgery group (n =16),Ibo group (n =16) and EPO treated group (n =16).Brain injury model was established by Ibo 1μl (5 μg) injected into left hippocampus.In EPO treated group,intraperitoneal injection of 5000 U/ (kg · d) EPO was performed for 3 consecutive days after injection of 1 μl Ibo into left hippocampus.Mice in sham surgery group and Ibo control group were treated with saline in the same dose instead.The pathological changes of neurons in hippocampus were observed 3 d after modeling in each group with Nissl staining,the level and activity of caspase-3 in hippocampus were determined by ABCELISA and spectrophotometry.Result After modeling,degeneration and death of neurons in hippocampuswith substantially decrease in number of intact neurons were found under light microscopy in Ibo group in comparison with sham surgery group.However,compared with the Ibo group,pathological changes in EPO treated group were less serious.The level of caspase-3 in Ibo control group was significantly higher than that in sham surgery group (P＜0.05),and the level of caspase-3 in EPO treated group was significantly lower than that in Ibo group (P ＜ 0.05).Conclusions The level of caspase-3 is significantly up-regulated in hippocampus of mice with Ibo-induced brain injury,leading to neuron apoptosis.EPO mitigates brain injury and plays a role of protection on brain function,suggesting the mechanism is attributed to decrease in caspase-3.
