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 investigate etiopathogenisis,modus operandi and rehabilitation in treatment of bone nonunion and residual deformity (cubitus valgus) after humeral lateral condyle fractures in children. [Method]The author retrospective summarized a total of 27 patients diagnosed with humeral lateral condyle fracture follow with bone nonunion and/or cubitus valgus consecutive enrolled in Children’s Hospital of Chongqing Medical University from 2001 to 2006,including 19 cases of male,8 cases of female,16 cases of right humeral lateral condyle fracture and 11 cases of left. The mean age at injured for all the patients (n =27) was 5.6 yr (range 3-10 yr).The mean age at suigical operation for all the patients (n =27) was 9 yr (range 5-14 yr).The average time from injury to operation was 2.8 yr (range 8mon-10 yr).There were three modus operations including direct normal position internal fixation of 7 cases,open reduction following os illium bone graft internal fixation of 11 cases,distant humerus varus wedge shape cut orthopaedic for 9 cases.[Result]Thirteen patients were followed up ranging from 6 month to 2 years,and 14 patients over 2 years. All the patients were achieved union for 8 to 16 weeks after surgery. Elbow deformity had been corrected and function of elbow joint had been recoverd satisfactorily. All of them,excellent rerult were found in 13 cases,good in 11 cases,and poor in 3 cases,the excellent and good rates was 88.9%. None of the cases happened with osteonecrosis,traumatic arthritis and myositis ossificans.[Conclusion]It is common that delay treatment of humeral lateral condyle fractures in children can result in bone nonunion and residual deformity (cubitus valgus) and it is difficult for treatment. Corresponding surgical treatment with different condition and early exercise can improve the appearance and function of elbow joint.

Objective To evaluate the treatment and p re vention of urethral stricture complicated by transurethral vapo-resection of pr ostate (TVP). Methods Retrospective analysis was conduct ed by reviewing medical records and following up the patients under study.Among 3012 patients with benign prostatic hyperplasia treated with TVP, urethral stric ture occurred 4 weeks to 22 months following surgery in 95 cases (3.15 %), inclu ding anterior in 47 (49.5%),posterior in 31 (32.6 %) and bladder neck contractur e or occlusion in 17 (17.9%).Their mean age was 68.7 years (range, 55 to 85 year s). Results The 95 patients were followed up for 4～36 m o nths (mean,14 months).Of them,65 cases underwent conventional dilation, in them 59 (90.8%) were cured and 6 had failure,then turning to internal urethrotomy;19 cases underwent internal urethrotomy plus dilation,in them,13 (68.4%) were cured and 6 had failure,then turning to urethroplasty;17 cases of bladder neck contra cture or occlusion underwent transurethral resection of bladder neck scar tissue ,with a cure rate of 88.2% (15 were cured and 2 experienced failure). Conclusions Urethral stricture is a common complication after TVP. The key points of managing the strictures are patients’ alert,close follow-up and early effective treatment.

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 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 investigate the changes of intestinal floras in elderly patients with first-episode untreated schizophrenia and to analyze the role of intestinal floras in schizophrenia .Methods Thirty elderly patients(≥60 years old) with first-episode un-treated schizophrenia treated in our hospital from July to October 2016 were selected as the observation group ,while 30 healthy peo-ple undergoing physical examination in the same period were selected as the control group .The bifidobacterium ,lactobacillus and bacteroides of stool samples in the two groups were tested by 16SrRNA real-time fluorescence quantitative PCR (qPCR) .Results The bifidobacterium content of stool samples in the observation group was significantly lower than that in the control group ,while the bacteroides content was significantly higher than that in the control group ,moreover the ratios of bacteroides/lactobacillus and bacteroides/bifidobacterium in the observation group were significantly increased ,the difference was statistically significant (P<0 .05);the lactobacillus content had no obvious difference between the two groups .Conclusion The phenomena of intestinal flora disorder and intestinal flora disproportion exist in elderly patients with first-episode untreated schizophrenia .Intestinal flora may be involved in the pathogenesis of schizophrenia .

Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50％ on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective To evaluate the effect of dexmedetomidine on the cell apoptosis during the acute lung injury induced by blunt chest trauma in rats.Methods Thirty pathogen-free male SpragueDawley rats,weighing 240-270 g,aged 8 weeks,were divided into 3 groups (n=10 each) using a random number table:shan operation group (group Sham),blunt chest trauma group (group T) and blunt chest trauma plus dexmedetomidine group (group TD).The model of acute lung injury was induced by dropping a 300 g weight onto a precordium in anesthetized rats.After the model was established,dexmedetomidine was intravenously infused at a rate of 5 μg · kg 1 · h-1 for 6 h in group TD.At 6 h after the model was established,blood samples were collected from the femoral artery for determination of concentrations of serum tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6).The rats were sacrificed after blood sampling,and lungs were removed for examination of the pathological changes (with light microscope) and for determination of Bax and Bcl-2 expression in lung tissues (by immuno-histochemistry) and cell apoptosis (by TUNEL).Bcl-2/Bax ratio and apoptosis index (AI) were calculated.Results Compared with group C,the serum TNF-α and IL-6 concentrations and AI were significantly increased,the expression of Bax and Bcl-2 was up-regulated,and Bcl-2/Bax ratio was decreased in T and TD groups (P＜ 0.01).Compared with group T,the serum TNF-α and IL-6 concentrations and AI were significantly decreased,the expression of Bax in lung tissues was down-regulated,the expression of Bcl-2 in lung tissues was up-regulated,Bcl-2/Bax ratio was increased (P＜0.05),and the pathological changes of lung tissues were significantly attenuated in group TD.Conclusion The mechanism by which dexmedetomidine mitigates the acute lung injury induced by blunt chest trauma is related to inhibition of cell apoptosis in rats.

Objective To explore the efficacy and side effect of inductive chemotherapy with lowdose,cytarabine,homoharringtonine and granulocyte colony-stimulating factor(CHG) in elderly acute myeloid leukemia(AML). Methods Thirty-five elderly patients (age＞60 years) with AML were enrolled for the initial treatment with CHG regimen,The CHG regimen consisted of cytarabine 10 mg/m2 per 12 h by subcutaneous injection,days 1-14,homoharringtonine 1 mg/m2 per day by intravenous continuous infusion,days 1-14,and G-CSF 200 μg/m2 per day by subcutaneous injection 12 h before chemotherapy,days 0-14. G-CSF only was used when white blood cell count(WBC) was less than 20×109/L during the whole course. Results After the first course,12 patients achieved complete response (CR),15 patients achieved partial response(PR),and 8 patients had no response(NR). After the second course,5 of 15 PR patients achieved CR,2 of 8 NR patients achieved PR. The total effective rate was 82 % (29/35). Of those 17 CR patients,eleven patients continued maintenance therapy and remained in remission for 12-34 months with a median CR duration of 18 months,the other 6 patients relapsed and were treated with original regimen,including one achieved CR again,4 achieved PR,and 1 achieved NR. The CHG regimen had mild hematologic toxicities and no severe nonhematologic toxicities. Conclusion CHG regimen is effective and well tolerated in remission for elderly AML.
