Anterior communicating artery (AcomA) aneurysm is one of the most common intracranial aneurysms.Interventional treatment of wide-neck AcomA aneurysms remains challenging.With the emergence of several intracranial stents and the innovation and development of a variety of stent technologies,stentassisted coiling (SAC) embolization has gradually become one of the preferable techniques for the treatment of wide-neck AcomA aneurysms.This article reviews several SAC embolization techniques of AcomA aneurysms.

Objective To evaluate and compare two definitions for metabolic syndrome(MS)issued by International Diabetes Federation(IDF)and by Chinese Medical Association Diabetes Branch(CDS).Methods An epidemic survey and physical examination were conducted among 481 subjects randomly selected from 3 354 subjects(above 40 years old)by cluster sampling.Results The prevalence rate of MS by IDF or by CDS definition were 40.96% and 38.05%,respectively.Kappa value was 0.51,P0.01).Metabolic disorder ratio for above 3 items by IDF was higher than that of CDS criterion.Conclusion The IDF diagnostic criterion for MS and CDS are in good accordance and applicability.The MS diagnostic criterion of IDF is better at diagnosing centricity obesity than that of CDS.

Objective To compare the characteristics and abnormity of lipid metabolism among three groups of population in Yangpu.Methods The data of blood lipids of three subpopulations were collected by epidemiologic investigation and experimental examination.Results The abnormal rates of total cholesterol and triglycerides were 50.85% and 56.91% in patients with coronary heart diseases;41.28% and 46.82% in patients with diabetes,23.58% and 32.46% in staffs of enterprises.The abnormal rates of total cholesterol and triglycerides were 43.55% and 51.75% in over-weight subjects,and all of them were higher than those in subjects with normal body mass index.The abnormal rate of triglycerides was significant higher in subjects with abnormal ratio of waist-hip(46.35%) than that with normal ratio(39.77%,P

Objective To explore the difference of serum free fatty acid(FFA) composition between the patients with the metabolic syndrome(MS) and the patients with high risk for MS(HRMS),and the relationship of FFA composition with their serum glucose.Methods The serum fatty acid profile was measured with the gas chromatography and mass spectrometer(GC/MS)in 159 patients with MS or HRMS and 43 control subjects.Results The contents of unsaturated fatty acid(UFA,C18:2 and C20:3),the ratios of UFA/TFA(total fatty acid),PUFA(polyunsaturated fatty acid)/TFA and PUFA/SFA(saturated fatty acid) were significantly increased in patients with MS than those in the normal controls(P0.05).FBG had remarkably positive correlation with UFA/TFA,PUFA/TFA and PUFA/SFA(r=0.229,0.204,0.230,P

Objective To compare the efficiency of compressive bandage dressing and drainage on the blood loss after total knee arthroplasty (TKA). Methods Patients (n=120) who visited Tianjin General Hospital Bin Hai Branch and Tianjin People's Hospital due to varus knee osteoarthritis and underwent TKA were retrospectively analyzed.There are 20 males and 100 females with, mean age was 65.18±6.88 years. Depending on whether placement of drainage, patients were divided into drainage group (60 cases) and pressure bandage dressing group (60 cases). Blood loss, blood transfusion and full blood count (FBC) were all analyzed after TKA in both groups. Results Blood loss after TKA in drainage and pressure dressing group were (1 026.85±274.44),(789.52±251.58) mL respectively. Blood loss was less severe in pressure dressing group than that in drainage group (t=4.938, P<0.01). Allogeneic transfusions were needed in 14 cases of drainage group and five cases of pres?sure bandage dressing group. The circumstances that requires blood transfusion was significantly lower in pressure bandage group than that in drainage group (χ2=5.065, P<0.05). The postoperative limb swelling and postoperative joint mobility did not show statistical significance (P>0.05). Conclusion Application of compressive bandage dressing in TKA surgery is easy to be operate and can reduce perioperative blood loss and allogeneic transfusion incidence.

BACKGROUND:There are numerous studies on bone marrow mesenchymal stem cells(BMSCs)from small animals such as rats and rabbits,but no few reports addressing BMSCs from big animals.OBJECTIVE:To observe in vitro cultured goat BMSCs,and to understand its biological properties.METHODS:A healthy Chinese goat aged ten months was obtained to extract 5 mL fresh bone marrow from the posterior superior iliac spine by puncture following anesthesia.Using the whole bone marrow method,the samples were incubated in a sterile plastic culture flask and added with DMEM/F12 containing 10% fetal bovine serum.Following 80% 90% confluence,cells were digested by trypsin.Cells at passage 3 in logarithmic phase were collected and frozen,and then recovered.Changes in cell morphology were observed using an inverted microscope.Cell growth curve was measured using MTT assay.The potential of osteogenic differentiation was examined utilizing Von Kossa's staining.RESULTS AND CONCLUSION:The primary cultured BMSCs were cultured with adherent growth.The cells were spindle form.Cell morphology following passage 3 was similar,showing long spindle shape.Following freezing and recovery,cell adherence was slower compared with subculture cells,and no significant difference was detected in cell morphology and viability compared with subculture cells.Growth cycle was similar in passage 3-passage 5 cells.BMSCs entered lag phase at days 2 and 3,logarithmic phase at day 3,and platform phase at days 6 and 7,and then growth speed was slow.Goat BMSCs were positive for Von Kossa's stain at 3 weeks following osteogenic induction.Results verified that cultured goat BMSCs showed strong genetic stability and proliferation ability,and differentiated into osteoblasts.

Objective To investigate the risk factors for mild cognitive impairment (MCI) in elderly people in Beijing.Methods Using multistage cluster random sampling,129 elderly people aged 60-80 years living around Dongzhimen communities were interviewed by mini-mental state examination (MMSE) and National Institute of Neurological and Communicative Diseases and Stroke/ Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria for screening MCI and Alzheimer's disease (AD).Results Thirty-seven cases (28.7%) had amnestic MCI (aMCI),thirty-six cases (27.9%) had AD,and fifty-six cases (43.4%) were with normal cognitive state (NCS).The age was older in aMCI patients or AD patients than in NCS[(67.6±7.5)y vs.(62.5±7.9)y,(67.6±7.5)y vs.(62.5±7.9)y,both P<0.01],Andthe aMCI or AD patients had low level of education (P<0.05).The blood pressure was higher in the patients suffered from aMCI or AD than in people with NCS more or less (P<0.05).The prevalence of aMCI was related to the body mass index (BMI) (P<0.05),while that of AD had no significant relation with BMI (P>0.05).The prevalence of aMCI or AD was not significantly different between male and female or between different birth months.(all P>0.05).Conclusions The prevalence of aMCI increases with age,lower level of education,higher level of blood pressure and BMI,while it has no significant relations with gender or birth month.
