Objective To prospectively study the minimally invasive hematoma stereotactic aspiration and the recovery of neurological deficits after conservative medical treatment alone, as well as the incidence of post-stroke depression (PSD) in patients with intracerebral hemorrhage, so as to investigate the effect of minimally invasive hernatorna stereotactic aspiration on the recovery of neurological deficits and the incidence of PSD. Methods Fifty-five patients with intracerebral hemorrhage received minimally invasive hematoma stereotactic aspiration (n =25) and conservative medical treatment (n = 30), respectively. The neurological deficits of the patients were assessed by the National Institutes of Health Stroke Scale (NIHSS) at admission, day 14 and 90. The decreased values (all compared to baseline score) of the NIHSS scores were calculated at day 14 and 90, respectively; the modified Rankin Scale (mRS) was used to assess the disabled degree at day 90; the 17-item Hamilton Depression Rating Scale (HAMD) was used to assess the PDS status at day 14 and 90. The correlation between PSD and the degrees of neurological deficit and disability in patients was analyzed. Results The decreased value of the NIHSS score in the stereotactic group at day 14 and 90 was significantly higher than that in the conservative treatment group (all P ＜0. 05), and the value of the mRS score was significantly lover than that in the conservative treatment group at day90 (P＜0. 05). The incidence and the total incidence of PSD in the stereotactic group at day 90 were significantly lover than those in the conservative treatment group (all P ＜0.05). There were significant positive correlation between HAMD and NIHSS scores and HAMD and mRS scores. Conclusions The recovery of neurological deficits was faster after the minimally invasive hematoma stereotactic aspiration. The degree of disability in patients was lower, and the incidence of PSD was also lower than that in the conservative treatment group. PSD was closely correlated with the degrees of neurological deficits and disability.

Transient ischemic attack (TIA) traditionally refers to temporary brain dysfunction lasting no longer than 24 hours due to a shortage of blood and oxygen, without any residual neurological deficit. In recent years, the development of imaging technology enables us to have a new awareness about TIA. This article reviews the effects of MRI, especially diffusion-weighted imaging, in the diagnosis and prognostic prediction of TIA.

0.1 improved significantly, while the eyesights of the other patients improved slightly or not at all. In the 53 cases of mass diseases,45 cases (84.9 %) required complete removal whereas 8 cases required bulk removal. No cases of sunken eyeball was found. Snuffle was improved in all cases. Most symptoms disappeared and no optic nerve injury resulted after the tumors in the orbital apex were removed. CONCLUSION Selecting the proper operative approach is important to the uncovering of the operative area. The use of navigation systems and endoscope could increase the rate of complete removals,result in fewer injuries of vessels and nerves,and avoid facial incision.

Objective:Hyperoxia is a necessary therapy in some neonatal diseases, and long-term therapeutic hyperoxia may induce severe damaging effects on intestinal epithelial cells.The aim of this study was to investigate whether hyperoxia could promote the expression of ASK1 and P38 in intestinal epithelial cells through ROS.Methods:The human colon adenocarcinoma cell line Caco-2 cells were treated with different concentrations of H 2O 2(100 μmol/L, 200 μmol/L and 400 μmol/L)and 85% oxygen in vitro.The expression of ASK1 was detected by immunofluorescence, and the expression of P38 and p-P38 were detected by Western Blot and Real-time PCR. Results:With the increase of H 2O 2 concentration, the fluorescence intensity of ASK1 increased.The fluorescence intensity of ASK1 in the hyperoxia group was significantly stronger than that of the control group and the H 2O 2 groups.With the increase of H 2O 2 concentration(100 μmol/L、200 μmol/L、400 μmol/L), the expression of P38 protein(0.21±0.02, 0.28±0.13, 0.44±0.07)and p-P38 protein(0.09±0.02, 0.19±0.03, 0.37±0.07)gradually increased.The expression of P38 mRNA in 200 μmol/L and 400 μmol/L H 2O 2 groups(4.03±0.68、3.94±0.71)was significantly higher than that in 100 μmol/L H 2O 2 group(3.05±0.47)( P<0.01). The expressions of P38 protein, p-P38 protein and P38 mRNA in the hyperoxia group were significantly higher than those in the H 2O 2 group( P<0.01). Compared with the control group, the expressions of P38 protein, p-P38 protein and p38 mRNA in the hyperoxia group and H 2O 2 groups increased significantly( P<0.01). Conclusion:The expression of ASK1 and P38 in intestinal epithelial cells increased significantly under hyperoxia, which indicated that hyperoxia might activate ASK1 and thereby regulate the expression of downstream P38 through ROS, resulting in intestinal epithelial cells damage.

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6％ (4/87 cases).The frequency of headache was not significantly different between the test group (2.4％) and control group (6.7％) (P =0.617).And the overall frequency of backache was 19.5 ％ (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4％,control group:17.8 ％,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95％ CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 ％ CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.

Background The protective effects against reperfusion injury of cardioprotective drugs have recently been evaluated and found to be inadequate. Guanxinshutong (GXST), a combination of the traditional herb and Mongolian medicine, is effective and safe in treating angina pectoris in clinical trials. We assess the cardioprotective effects of GXST against myocardial ischemia and reperfusion (MI/R) injury in rats and explore its possible mechanism. Methods Forty-five male Sprague Dawley rats were randomized into three groups: non-MI/R group (Sham, n = 15), MI/R group treated with vehicle (Control, n = 15) and MI/R group treated with GXST (Drug, n = 15). MI/R was induced by ligation of the left anterior descending coronary artery (LAD) for 30 minutes, followed by 2/24 hour reperfusion in the Control and Drug groups. In the Sham group, the LAD was exposed without occlusion. GXST powder (in the Drug group) or saline (in the Control and Sham groups) were administered via direct gastric gavage from 7 day prior to surgery. Blood samples were collected from the carotid artery (10 rats each group) after 2 hours of reperfusion, to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) using enzyme-linked immunosorbent assays. The animals were then sacrificed and the hearts were harvested for histopathology and western blot analysis. Infarct size was measured in the remaining five rats in each group after 24 hours reperfusion. Results GXST significantly decreased levels of TNF-α, IL-1β, IL-6, ICAM-1, apoptosis index (AI) and infarct size. GXST also obviously inhibited nuclear factor kappa B (NF-κB) activity when compared with the Control group (all P < 0.05). Conclusions GXST is effective in protecting the myocardium against MI/R injury in rats. Its possible cardioprotective mechanism involves inhibition of the inflammatory response and apoptosis following MI/R injury.

Objective To analyze the clinical characteristics and prognosis of disseminated cryptococcosis in children.Methods The data of disseminated cryptococcosis inpatients were reviewed retrospectively at Beijing Children's Hospital,Capital Medical University,from January 2002 to September 2014.The demographic data,clinical manifestations,laboratory findings,imaging,antifungal treatments and outcomes of all the patients were analyzed.Results Overall 25 children with disseminated cryptococcosis were enrolled including 17 boys(68.0％).The average age was 7 years old.Four cases (16.0％) had underlying conditions,among them 1 case had human immunodeficiency virus(HIV)-positive.The median time to diagnosis was 32 (23-47) days,44.0％ of the patients (11 cases) were misdiagnosed,and 8 cases misdiagnosed as tuberculosis.All patients had fever.Other common clinical manifestations included cough (16 cases),headache (10 cases),vomiting (10 cases),altered mental status (6 cases) and stomachache (6 cases).Respiratory system involvement was seen in all cases,central nervous system was involved in 18 cases,other organ involvement included lymph nodes,spleen,liver,kidney,skin,skeleton and costicartilage.Amphotericin B (AmB) + Fluconazole (Flu) ± 5-flucytosine (5-FC) was the most common therapy (15 cases),Flu ± 5-FC for 6 cases,AmB ± 5-FC for 2 cases,Voricanazole (VOR) for 1 case.Sixteen cases (66.7％) got recovery/improved on discharge,8 cases (33.3％) rejected to the advise and discharged with treatment failure,and the HIV-infected patient transferred to a special hospital.Fifteen patients (60.0％) were followed up,and 13 cases (87.0％) showed recovery,but 2 died in the long-term prognosis.Conclusions Disseminated cryptococcosis in children is more common in school-age boys.Most patients are without underlying conditions.Disseminated cryptococcosis can cause multiple organ damage.Patients with prolonged fever,cough,headache,with or without underlying diseases,can be suspected as disseminated cryptococcosis.Blood and cerebrospinal fluid culture for fungus,cryptococcal antigen should be performed for early diagnosis and treatment.
