Objective To discuss the feasibility of treating patients with severe aortic valve stenosis by aortic valve replacement via transfemoral balloon dilation. Methods Three patients with severe aortic valve stenosis, who could not tolerate traditional open surgery, were chosen to receive aortic valve replacement via transfemoral balloon dilation. Results All the three operations were successfully done by transfemoral approach, including one assisted by transapical puncture. The aortic valve function of patients was improved, and there was no related complication or death. Conclusion Aortic valve replacement via transfemoral balloon dilation can be used for treatment of Chinese patients with severe aortic valve stenosis; but which demands more detailed preoperative preparation, evaluation, and surgical manipulation.

Objective To investigate effects of volume,distribution and leakage of bone cement in ver- tebroplasty on the adjacent intervertebral bodies using an experimentally calibrated and anatomically accurate fi- nite-element model of elderly L4-L5 vertebral bodies.Methods Computed tomography(CT)scanning was done,at 1 mm intervals,on L4-L5 vertebral bodies of the lumbar spine of an old man cadaver that had no abnormal findings on rnentgenograms.The L4-L5 motion segment data were obtained from the CT scans to establish in computer a three-dimensional finite element model of L4-L5 functional spinal unit(FSU)with the software Ansys 7.0.Compressive load after virtual vertebroplasty on the damaged model,unipedicular and bipedieolar injections and leakage of cement into the intervertebral space,and the resulting endplate and disc stresses of the adjacent vertebral bodies were analyzed in various spatial distributions of the filling material and different loading conditions. An anatomically accurate finite-element model of elderly L4-L5 vertebral bodies was developed.Results The FSU study suggested that changes in stress and strain at adjacent levels were minimal.Furthermore,endplale and disc stresses of the adjacent vertebral bodies were not influenced by bone cement filling volumes or distributions except under bending,whereas asymmetric distribution and leakage of bone cement to the disk increased the stress of adjacent endplates.Conclusion Since asymmetric distribution and significant leakage of cement into the intervertebral space can increase the stresses of endplates of adjacent vertebral bodies and may lead to a fracture, symmetric placement of cement in operation should be achieved and leakage of cement avoided.

OBJECTIVETo evaluate the efficacy and safety of tiaogan Lipi Recipe (TLR) in treating non-alcoholic fatty liver disease (NAFLD) patients of Gan stagnation Pi deficiency syndrome (GSP-DS).

METHODSA randomized, double blind, placebo-controlled clinical trial was performed. Totally 99 NAFLD patients of GSPDS were randomly allocated into two groups, 66 patients in the treatment group (treated with-TLR, one dose per day) and 33 patients in the control group (treated with placebos, one dose per day). The therapeutic course for all was 12 weeks. All patients received lifestyle interventions including moderate aerobic exercise, moderate caloric restriction, and dietary changes. Clinical symptoms, CT indices, liver functions and blood lipids were observed before and after treatment.

RESULTSAfter 12 weeks of treatment, the total score of clinical symptoms decreased in the two groups (P <0. 01), and it was lower in the treatment group than in the control group (P <0. 05). Liver/spleen CT ratio increased in the treatment group (P <0. 01), and it was higher in the treatment group than in the control group (P <0. 01). After treatment levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) all decreased in the treatment group (P <0. 05, P <0. 01), while levels of ALT decreased in the control group (P <0. 05). Besides, all the 3 levels mentioned above were lower in the treatment group than in the control group (P <0. 05). Levels of total cholesterol (CHO) and triglyceride (TG) decreased in the two groups (P <0. 05), and they were lower in the treatment group (P <0. 05). Total effective rates of TCM syndrome, abdominal CT, liver functions, and blood lipids were 79. 69% (51/64 cases), 54. 69% (35/64 cases), 67. 65% (23/34 cases), and 67. 39% (31/46 cases) in the treatment group, while they were 56. 25% (18/32 cases), 25. 00% (8/32 cases), 33. 33% (6/18 cases), and 55. 56% (10/18 cases) in the control group. All were superior in the treatment group (P <0.05, P <0.01, respectively).

CONCLUSIONTLR combined with lifestyle intervention could safely and effectively improve clinical symptoms of NAFLD patients of GSPDS, elevate liver/spleen CT ratios, and play a role in liver protection, anti-inflammation, and lowering blood lipids.

Objective To investigate the changes in characteristics of periodontal pathogens in subgingival plaque of patients with puberty gingivitis and its relevance with clinical symptoms.Methods A total of 108 subgingival plaque samples were collected from 30 patients with puberty gingivitis(Guoup G),9 cases of chronic periodontitis(Group P)and 15 healthy controls(Group H).The age of the 54 participants was from 11 to 17.The black-pigmented bacteria(BPB),Fusobacterium nucleatum(Fn),Actinobacillus actinomycetemcomitans(Aa),Actinomyces were detected using bacterial culture.The probing depth(PD),gingival index(GI),bleeding index(BI)and attachment loss(AL)were also recorded.Results In all these three groups,the detection rates of black-pigmented bacteria were:3%,30%and 100%;Fn were:30%,68% and 94%,statistically significantly different(P<0.01).The lgCFU/ml of black-pigmented bacteria and Actinomyces was higher in mild-moderate group[(3.8±0.7)and(5.3±0.9)]than in Group H(P<0.001).The lgCFU/ml of black-pigmented bacteria and Fn significantly was higher in severe inflammation group[(4.7±1.2)and(4.4±0.8)]than in the mild-moderate group(P<0.01).The lgCFU/ml of black-pigmented bacteria,Fn and Aa was higher in severe gingivitis group[(6.6±1.0),(5.5±1.0)and(4.2±1.7)]than in mild gingivitis group(P<0.01).The detection rate and IgCFU/ml of black-pigmented bacteria,Fn and Aa were both positively correlated with BI,PD and AL.Conclusions In the stage of severe gingivitis,the periodontal pathogens increased markedly,suggesting that risk of further destruction of periodontal tissue may exist.

Objective To explore the therapeutic effect of patients with intractable by microsurgical operation.Methods All patients assisted by a 3-dimensional precise localization system of epileptic foei for epilepsy diagnosis and the epileptogenic focus and comprehensive surgical measures were taken for the treat- ment of isolated epileptic foci and their network.The outcomes of 50 patients in the following up 1～2 years were defined.A retrospective review was conducted.Results In this group,Excellent 53 cases (31.90%);good 83 cases(50.93%);moderate 10 cases(6.13%)and poor 18 cases(11.04%).The ef- fective rate was 80%.Conclusion The microsurgical management is an effective approach for treatment of refractory epilepsy.

Objective To report the clinical effect of primary percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI).Methods A retrospective study was accomplished on the clinical data of 13 AMI patients who underwent PCI from March 2004 to April 2006.Results The infarct-related artery (IRA)was successfully recanalized by primary PCI for 12 AMI patients,without major complications occurred in these cases during hospitalization.Conclusion Primary PCI should be firstly chosen for treatment of AMI in the hospitals which could carry out PCI.
