BACKGROUND: Nanotechnology has widely used in tissue engineered reconstruction in recent years. Most reports are concerning carbon nanomaterials in bone reparation, but the study of peripheral nerve regeneration is poorly understood.OBJECTIVE: To improve the physical, chemical and biological properties of chitosan/collagen composite nerve conduit with functionalized carbon nanotubes, in addition, to investigate the therapeutic effect of this novel material.DESIGN, TIME AND SETTING: The same body controlled experiment of animals was performed at the Tissue Engineering Laboratory and The Key Laboratory of Thin Film and Microfabrication Technology, Shanghai Jiao Tong University from February 2005 to November 2006.MATERIALS: The carbon nanotubes were mixed with 2% chitosan solution, coated on the die to prepare chitosan/collagen composite nerve conduit with functionalized carbon nanotubes. The chitosan/collagen tubes were served as controls.METHODS: A total of 80 male adult-rats were prepared a 4 mm accessory nerve defects models, and repaired by nerve conduit in the experimental material and control material groups. In the auto nerve grafts group, the removed nerve was connected to the broken end. In the blank control group, there was no other treatment except removing 2 mm nerves. The left sides were served as experimental sides and the right sides as within-subject controls.MAIN OUTCOME MEASURES: The repairing outcomes were measured by electrophysiological, myophysiological, and histological measurements.RESULTS: The accessory nerve defects were repaired in a rat model using carbon nanotubes in chitosan/collagen-based composite nerve conduit. As time passed after the surgery, good results of the electrophysiological, myophysiological and histological measurements were achieved, which were similar or superior to those of the nerve autografts.CONCLUSION: The carbon nanotubes in chitosan/collagen-based composite can be an ideal candidate for peripheral nerve regeneration.

Objective To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis based on individual condition. Methods Twelve patients with intracranial venous sinus thrombosis were treated with endovascular management according to the severity and course of disease after they failed to respond to anticoagulant therapy. The clinical signs and symptoms,cerebrospinal fluid pressure and arteriovenous circulation time were observed and followed up (including MRV). Intravenous thrombolysis and mechanical thrombus maceration were carried out in all 12 patients,while intravenous thrombolysis, mechanical thrombus maceration in combination with intra-arterial thrombolysis were employed in 3. After the treatment, anticoagulant therapy was carried out for 6 months.The patients were followed up for 12 to 24 months. Results Of the twelve patients, clinical signs and symptoms included slight headache (2 cases), mild hemiplegia (1 case), ambiopia or blurred vision (3 cases). The cerebrospinal fluid pressure returned to under 26 cm H2O (1 cm H2O =0.098 kPa)following treatment from 28 to 38 cm H2O [ mean (32. 4 ±3.0) cm H2O] in preoperative measurement and the arteriovenous circulation time returned to below 10 s in all patients following treatment. Neither recurrence of thrombosis nor new symptoms of neurologic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation with the exception of a subcutaneous bleeding at the venopuncture site. Conclusion Endovascular treatment is effective and safe for patients with intracranial venous sinus thrombosis.

Objective To study the effects of diterpene ginkgolides meglumine injection ( DGMI) on memory impairment, activation of microglia and astrocytes and inflammatory cytokines in aged mice. Methods Twenty aged mice (22 months old) were randomly divided into two groups:aged mouse group(n=10) and DGMI group(n=10). Another 10 mice (2 months old) were selected as young mouse control group. The mice in DGMI group were received 5 mg/kg DGMI per day by tail vain injection for 4 weeks. The mice in the other two groups were received the same amount normal saline for 4 weeks. The Morris water maze was used to evaluate the function of spacial learning and memory after administration of drugs. The ex-pression of CD11b,GFAP,IL-1β,IL-6,TNF-α and NFκB in mice brain hippocampus were detected by West-ern blot. Results (1) The escape latency time of aged mouse group was significantly longer than that of young mouse control group from the 2nd day to the 7th day(P<0. 01). The times of platform crossing,time and distance in target quadrant of aged mouse group were significantly shorter than those of young mouse group (all P<0. 01). Compared with aged mouse group,DGMI significantly reduced the escape latency time of DGMI group (P<0. 01). DGMI increased the times of platform crossing,time and distance in target quad-rant of aged mouse group (P<0. 01). (2) The expressions of CD11b,GFAP in young mouse control group, aged mouse group and DGMI group were as follows respectively:CD11b:(1. 036±0. 023),(1. 757±0. 046), (1. 214±0. 024);GFAP:(1. 022±0. 071),(1. 344±0. 021),(1. 086±0. 073). DGMI reduced the expres-sion of CD11b and GFAP in hippocampus compared with aged mouse group ( t=5. 556,P<0. 01;t=5. 484, P<0. 01). (3) The expressions of IL-1β,IL-6,TNF-α and NFκB in young mouse control group,aged mouse group and DGMI group were as follows respectively:IL-1β:( 1. 003 ± 0. 057),( 2. 062± 0. 105),( 1. 182± 0. 084);IL-6:(1. 018±0. 024),(1. 583± 0. 052),( 1. 152± 0. 031); TNF-α:( 1. 021± 0. 054),(1. 449± 0. 053),(1. 211±0. 036);p-NFκB:(1. 052±0. 034),(1. 782± 0. 113),( 1. 158± 0. 066). DGMI reduced the expression of p-NFκB(t=6. 547,P<0. 01) and pro-inflammatory cytokines including IL-1β(t=8. 513,P<0. 01),IL-6(t=3. 421,P<0. 01) and TNF-α( t=5. 562,P<0. 01) in hippocampus compared with aged mouse group. Conclusion DGMI can improve the ability of learning and memory in aged mice. The mecha-nism may be related with inhibiting activity of microgliosis,astrocytosis,NFκB and neuroinflammaton.

Objective:To explore the application effect of traditional Chinese medicine comprehensive nursing on elderly patients with coronary heart disease(qi stagnation and blood stasis type) constipation.Methods:A total of 126 elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation were divided into the control group and the experimental group by random digits table method, 63 cases each; the control group received routine nursing, and the experimental group was given traditional Chinese medicine comprehensive nursing; comparing the two groups of patients defecation, mental state, recurrence rate, and nursing satisfaction.Results:There was no significant difference in defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and self-Rating Anxiety Scale (SAS) score( P >0.05). After one month of nursing, defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and SAS score were (4.09±0.86) times/week, (5.12±1.24) min/time, (2.57±0.39) points, (1.53±0.31) points, (0.97±0.21) points, (49.27±4.15)points in the experimental group, (3.12±0.61) times/week, (6.87±1.52) min/time, (2.59±0.36) points, (2.02±0.44) points, (1.29±0.27) points, (54.42±6.01) points in the control group, the differences were significant ( t values were -6.638-7.081, all P<0.05). Within 1 month after nursing, the recurrence rate of constipation in the experimental group (14.3%, 9/63) was lower than that in the control group (74.6%, 47/63) , and the satisfaction rate of the experimental group (98.4%, 62/63) was higher than that in the control group (69.8%, 44/63) , the differences were significant(× 2 values were 46.414, 19.257, P<0.05). Conclusions:Traditional Chinese medicine comprehensive care for elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation can significantly improve their defecation and psychological state, and can reduce the recurrence rate and improve the patient's satisfaction with nursing, which deserves further clinical application and research.

E2F1, a nucleoprotein gene belongs to transcription factor, is closely associated with the development of malignant tumours. Long non-coding RNAs (lncRNAs) are aberrantly expressed in a variety of tumors. In studies of molecular mechanisms associated with lncRNAs and tumours, E2F1 has been identified as a key factor that can play a critical role as an upstream regulator or downstream target of lncRNAs, and even inter-regulate to form a positive feedback loop. This paper reviews the significance of the interaction between E2F1 and lncRNA in malignant tumors in recent years, and aims to provide ideas for the study of tumor mechanisms.

OBJECTIVE: To explore the genetic basis for a child with multiple malformation and growth retardation. METHODS: The child was subjected to low-coverage massively parallel copy number variation sequencing (CNV-seq) based on next generation sequencing (NGS) technique. RESULTS: G-banding karyotyping analysis has found no abnormality in the boy and his parents. CNV-seq analysis discovered that the child has carried a heterozygous 4.36 Mb deletion (24 020 000-28 380 000) at 7p15.3p15.1. The same deletion was not found in either parent. The deletion has encompassed 28 OMIM genes including HOXA13, CYCS, DFNA5, HOXA11 and HOXA2. Among these, HOXA13 has been associated with distal limb deformity, hypospadias and cryptorchidism. HOXA1, HOXA3 and HOXA4 are involved in the formation of cardiac primordia and primordial tube, and HOXA2 is involved in the development of auditory system. The clinical phenotype of the child was consistent with that of 7p15 deletion syndrome. CONCLUSION Haploinsufficiency of HOXA1, HOXA2, HOXA3, HOXA4 and HOXA13 genes may underlie the clinical phenotype of the child, which is comparable to 7p15 deletion syndrome.
