Objective To explore the risk factors for intracranial hemorrhage caused by late vitamin K deficiency bleeding(VKDB),in order to prevent and reduce the incidence of intracranial hemorrhage caused by late VKDB.Methods A retrospective analysis of the risk factors of late VKDB and intracranial hemorrhage was applied to 2 groups of patients in PICU and department of neurology of Beijing children's Hospital from Jan.2002 to Dec.2007.In group Ⅰ,there were 90 patients suffering from intracranial hemorrhage caused by late VKDB;while in group Ⅱ,there were 23 patients of late VKDB without intracranial hemorrhage.Within 12 hours of hospitalization,the following 9 items were checked:the cranial CT,blood calcium concentration,liver function,serum sodium,blood glucose,prothrombin time,partial thromboplastin time,fibrinogen concentration,and platelet.Ten possible relevant risk factors of gender,age,birth situation,feeding patterns,recent diarrhea,cytomegalovirus(CMV)infection,hypocalcemia,dysglycemia,hyponatremia,and abnormal liver function were analyzed by the method of non-conditional Logistic regression analysis.Results Statistically significant difference had been found in the 3 factors of hypocalcaemia,recent diarrhea,abnormal liver function(Pa

Up to now, a variety of microRNAs have been found in a number of studies, that specifically expressed in retinal neuroepithelial, lens, cornea and retinal pigment epithelium, in which miR-126 plays a certain role in the proliferation of tumor cells, the development of thymus lymphocytes and cardiovascular diseases.Some researches show that miR-126 has certain correlations with the formation of corneal neovascularization, the development of diabetic retinopathy, and the immune system related eye disease.In this paper, the current miR-126 in the role of eye disease mechanism and research progress were reviewed.

The purpose of this study was to isolate and purify polysaccharide from Gynura divaricata and analyze its monosaccharide composition. A water-soluble crude polysaccharide was obtained by hot water extraction, ethanol precipitation and deproteinization after degreasing. The crude polysaccharide then purified with DEAE-Sepharose Fast Flow column chromatography and dialysis. The monosaccharide composition and structure were analyzed by HPLC, UV spectrophotometer and 1H-NMR. The results showed that the purity and molecular weight of GDPS-2 and GDPS-3 were 87.3%, 2.03 x 10(4) Da and 90.9%, 4.29 x 10(4) Da, respectively. The UV spectrophotometer and 1H-NMR data suggested that glycosidic bond of GDPS-2 and GDPS-3 were a type. Both GDPs-2 and GDPs-3 were homogeneous polysaccharides, and GDPs-2 was mainly composed of glucuronic acid and xylose at a molar ratio of 1.1:0.63. GDPs-3 was mainly composed of rhamnose, glucuronic acid, galactose, xylose and galacturonic acid at a molar ratio of 0.32:6.0:0.21:1.75:4.3.

BACKGROUND: Hepatic myelopathy results from liver disease, which lacks of effective cure method. Liver transplantation has attempted to cure this disease; however, the long-term therapeutic effect is rarely reported. OBJECTIVE: To explore the long-term therapeutic effect of liver transplantation in patients with hepatic myelopathy. METHODS: The clinical data of 2 patients with hepatic myelopathy, who underwent orthotopic liver transplantation, in August 2002 and November 2004, at the 309 Hospital of Chinese PLA, were analyzed retrospectively. The time of follow-up was 18 and 43 months, respectively. The muscle strength of double lower limbs in 2 patients was assessed prior to and after operation. RESULTS AND CONCLUSION: Two patients recovered well at 4 weeks after transplantation, the clinical symptom and physical signs of patients were improved obviously, the blood routine examination and other biochemical index were normal,and the function of transplanted kidney was normal. Two patients discharged at 6 weeks after transplantation. Patient 1 could stand for a long time at months 6 after transplantation, walked slowly with the supporter after 12 months and without the supporter at 43 months. The muscular strength of two lower limbs was grade 4. And the liver function was normal. Patients 2 could move his lower limbs in bed at months 6 after transplantation, walked with the supporter at 18 months. The muscular strength of two lower limbs was grade 3. The liver function was normal. It demonstrated that liver transplantation is beneficial to control hepatic myelopathy and recover muscular strength of two lower limbs. It is a newly developed, effective curing method for treating hepatic myelopathy. However, the numbers were small with short time observation, thus, the long-term therapeutic effect still need to be explored.

OBJECTIVE: To explore the relationship between polymorphism of apolipoprotein E (ApoE) exon 4 gene and different syndromes in patients with coronary heart disease (CHD). METHODS: Two hundred patients with CHD were divided into four groups according to syndrome differentiation, including syndrome of phlegm (PS), syndrome of blood stasis (BSS), syndrome of phlegm-blood stasis blocking (PBBS) and syndrome of non-phlegm and non-blood stasis (NPNBS). One hundred healthy volunteers were included in control group. Blood lipids were measured by routine examination. Total DNA of peripheral blood was extracted. ApoE genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. All data were analyzed by SAS software. RESULTS: (1)The occurrence rate of epsilon4 allele of ApoE in patients with CHD was 19.5%, significantly higher than 9.5% in the control group (P<0.05), and the E 3/4 genotype was especially more frequent (P<0.01). (2) The levels of total cholesterol (TC), total triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) in patients with epsilon4 were higher than those in patients without epsilon4 (P<0.01). (3) The frequencies of epsilon4 allele and E3/4 genotype in patients with PS were significantly higher than those in patients with BSS (P<0.05). CONCLUSION: ApoE epsilon4 allele, especially E3/4 genotype, is the risk factor of CHD. There is a relatively close relationship between patients with ApoE epsilon4 allele and PS. It may be one of the main susceptible genes in CHD patients with PS.

OBJECTIVETo evaluate percutaneous reduction by Kirschner pin and internal fixation with cancellous screw and plate through minimal incision at the lateral side of heel for the treatment of intra-articular displacement fracture of calcaneus.

METHODSFrom September 2009 to June 2012, 80 patients with close intra-articular displacement fractures of calcaneus were divided into treatment group and control group. There were 40 patients in the control group, including 21 males and 19 females, ranging in age from 23 to 64 years old, averaged (39.1 +/-11.7) years old; and the patients were treated with fixation by compress screws and plates of self-broken type. There were 40 patients in the treatment group, including 24 males and 16 females,ranging in age from 21 to 67 years old, averaged (39.6+/-14.3) years old;and the patients were treated with full thread cancellous screws and plates fixation. The fixation time,intra-operative blood loss and the number of injured medial plntar nerve were compared between the two groups. The Böhler angle, Gissane angle and the correction degree of calcaneal width were measured at 1 year after operation. The internal fixators were taken out after 1 year. The AOFAS ankle-hindfoot score was used to evaluate therapeutic effects.

RESULTSAll the patients were followed up,and the duration ranged from 9 to 32 months, with a mean of 16 months. There were shorter operation time, less injury, satisfactory postoperative Böhler angle and calcaneal width in treatment group compared with control group,which reduced the medial neurovascular injuries, and the plate was easily removed after fracture healing.

CONCLUSIONFull thread cancellous screws and plate fixation for the treatment of calcaneal fractures could get same therapeutic effects as compress screws and plate of self-broken type fixation, and also has follow advantages: shortening the operation time, reducing blood loss, easily to be removed, avoiding the medial neurovascular damage, reducing the incidence of complications.

Non-small-cell lung carcinoma (NSCLC) is one of the most frequently diagnosed malignancies worldwide.Previous studies have shown that microRNA-449b (miR-449b) functions as a tumor suppressor in many cancers.However,the role of miR-449b in NSCLC is still unknown.In the present study,miR-449b was significantly downregulated in NSCLC samples and cell lines.Bioinformatics analysis revealed that 3'-UTR region of leucine rich repeat containing G protein-coupled receptor 4 (LGR4) mRNA had putative complementary sequences to miR-449b,which was further confirmed by the luciferase assay.Western blotting showed that restoration of miR-449b in NSCLC cells decreased the expression of LGR4.Interestingly,over-expression of miR-449b inhibited growth and invasion of NSCLC cells in vitro.Furthermore,ectopic expression of LGR4 reversed miR-449b-suppressed proliferation and invasion of NSCLC cells.Therefore,the data of the present study demonstrate that miR-449b inhibits tumor cell growth and invasion by targeting LGR4 in NSCLC.
