Objective Cerebral infarction is a main disease threatening human health and the recurrence of cerebral infarction is more inclined to cause disability and death.The article aimed to explore the influence of total sleeping time on the recurrence of cerebral infarction.Methods According to the criteria, 70 cases of cerebral infarction patients who hospitalized in our hospital from March 2016 to November 2016 were selected to undergo polysomnography (PSG) and were divided into two groups according to medical history: original group and recurrence group.Another 20 simultaneous outpatients who had no significant diseases to undergo PSG were chosen as the control group.Data were collected on all the individual''s total sleeping time (TST), gender and age.Hypothesis testing and logistic related analysis were applied in data analysis.Results The TST of recurrence group was shorter than those of the original group and the control group (P<0.05), among which the TST of the original group is shorter than that of the control group (P<0.05), both representing significant difference.Multiple regression analysis showed that TST was an independent risk factor for the recurrence of cerebral infarction and that the risk of recurrence of cerebral infarction increased with the lack of TST.Conclusion The shortening of TST may increase the risk of the recurrence of cerebral infarction.

Ischemic cerebrovascular disease is one of the major reasons of mortality and disability in adult populations.Ultra-early recanalization is by far the most positive treatment.Relative to intravenous thrombolysis,various endovascular treatment modalities can extend therapeutic time window and increase the recanalization rate.Furthermore,interventional therapy can also improve the clinical outcomes of patients by increasing the perfusion of colhteral circulation.This article reviews various endovascular treatment modalities and their application validated in previous clinical studies in China.

[Objective] To explore the reasons of catheter-related infections in ICU critical pa-tients and raise up the countermeasures.[Methods] The clinical data of 46 patients with catheter-related infections were surveyed and analyzed from May 2010 to March 2011 in our hospital.[Results] Elderly patients occupied the majority of ICU patients with catheter-related infections.The main infection sites included the respiratory system,urinary system and gastrointestinal system.Establishment of artificial airway was the main cause of infection,indwelling catheter came next.[Conclusions] ICU patients has a high incidence of catheter-related infections.We should handle the ICU management appropriately,strengthen the control and prevention of factors of catheter-related infections,strictly enforce disinfection and segregation regulation,cut off infection way,enhances the resistance of patients,limit antibiotic use and various invasive operation in order to reduce the incidence of catheter-related infections.

Ultrasound brain perfusion imaging can evaluate brain perfusion in normal and pathological conditions. After basilar stent implantation, contrast-enhanced ultrasound (CEUS) can show normal visualization of color flow within the stent and provide essential functional information by evaluation of blood flow velocities. Furthermore, CEUS can estimate the volume of brain hemorrhage and readily identify residual tumor. CEUS can be used in thrombolysis, and will be applied in cerebral trauma. The value of CEUS in brain perfusion imaging was reviewed in this article.

Objective： To investigate the modification of GABAA receptor subunits in audiogenic seizure rat cortex and hippocampus when rendered tolerant to flurazepam. Methods： Rats were administrated with flurazepam for two weeks, which resulted in tolerance to flurazepam, in the absence of behavioral signs of withdrawal. GABAA receptor subunits α1, α3, α5, γ2L and γ2S were assayed using quantitative competitive RT-PCR in rat frontparietal motor(FrPaM) and hippocampus. Results： In FrPaM, the contents of mRNA encoding for α1, α3,　γ2L and γ2S were all significantly decreased (24%,17%,35% and 45% respectively),whereas that of α5 was significantly increased (33%) compared with the control. In hippocampus, α1, γ2L, and γ2S mRNA contents were significantly decreased (33%, 35%and 27% respectively). Conclusion： The accomodated change in GABAA receptor subunits α1, α3, α5,γ2L and γ2S in FrPaM and hippocampus may be associated with the mechanism of flurazepam tolerance in audiogenic seizure rats.

0.05), but there is statistic difference between the two groups in estimating the involvement of cervical canal and the earlier surgical stage than clinical stage(P

Objective In order to find the best methods for treatment of lumbar intervertebral disc herniation through posterior approach microendoscopic discectomy. Methods The approach of operation by lamina arcus vertebrae space was used to remove ligamentum flavum not to removed lamina arcus vertebrae and other tissue in lateral recumbent position. Extraction of lumbar interverebral disc herniation was used in 113 cases. Results A follow-up study was performed after operation, ranged from 6 to 24 months with a mean duration of 12 months. According to Nakai standard, there were 107 cases scored "excellent" and 6 scored "good". Conclusion Microendoscopic discectomy by the approach of lamina arcus vertebrae space caused less injury and bleeding, and was safe for both surgery and anesthesia. It achieved successfully without affecting the spinal stability.

Objective To inverstigate the CT findings of non-Hodgkin’s lymphomas in orbit and paranasal sinuses,nasal cavity.Methods 12 patients with non-Hodgkin’s lymphomas in orb it and paranasal sinuses,nasal cavity diagnosed pathology retrospectivly were an alyzed based on their CT data. Results 12 cases of all were non-Hodgin’s lymphoma.Ther e were lymphoma of orbit in 8 cases, lymphoma of maxillary sinus in 3 cases, lym phoma of nasal in 1 case .There was eyelid tumor in 3 cases, soft tissue tumefac tion in adjacent eyelid in 2 cases,soft tissue tumefaction in adjacent maxillary region of nose back in 3 cases and local bone absorption in 2 cases.Conclusion Tumors in orbit and maxillary sinus nasal cavi ty were not concomitant with bone destruction. The sicken tumefaction or tumors formed in adjacent eyelid and maxillay region of nose back are important clue of lymphoma.

Objective To understand the content of fluoride in dinking water in the rural area in Yaodu district and to provide the data for water improvement. Methods 873 water samples were randomly collected from 175 villages in Yaodu district during Apr.-Sep., 2006 and the fluoride ion selective electrode was used to determine the fluoride in dinking water. Results The eligible rate of fluoride concentration in the investigated drinking water samples was 54.75%. The range of fluoride concentration was 0.24-5.44 mg/L. Conclusion The investigated area is the moderate or severe prevalent area of endemic fluorosis, water improvement should be enhanced in this area.
