BACKGROUND: The effectiveness and safety of traditional Chinese medicine treatment for chronic obstructive pulmonary disease (COPD) have been preliminarily approved by clinical practices.OBJECTIVE: To investigate the effects of Gubenkeli capsule on the protein expression of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase1 (TIMP-1) in lung tissue of COPD model rats.METHODS: A total of 50 Wistar rats were randomly divided into five groups with 10 rats in each group: normal control, model, prednisone, Gubenkeli capsule-low dose, and Gubenkeli capsule-high dose. COPD rat models were established in all rats with the exception of the normal control rats by smoking and intratracheal instillation of LPS. At 29 days after COPD induction, rats from the prednisone, Gubenkeli capsule-low dose, Gubenkeli capsule-high dose groups were intragastrically administered prednisone (1.04 mg/kg per day), Gubenkeli capsule (0.4, 0.94 g/kg per day), once a day, to observer rat general conditions. Protein expression of MMP-9 and TIMP-1 in the lung tissue was detected by immunohistochemical methods. RESULTS AND CONCLUSION: Protein expression of MMP-9 and TIMP-1 in the lung tissue of COPD rats was significantly increased (P < 0.05). After drug intervention, the general conditions of COPD rats were greatly improved, and protein expression of MMP-9 and TIMP-1 in the lung tissue was decreased. Prednisone yields the strongest effects, followed by high-dose Gubenkeli capsule and low-dose Gubenkeli capsule. These findings demonstrate that Gubenkeli capsule alleviates the clinical manifestations of COPD model rats, improve airway remodeling, and correct the imbalance between prolease and antiprotease in a dose-response manner.

Objective To quantitatively assess the geometry configuration of mitral valve and annulus in the ischemic mitral regurgitation(IMR) and non-ischemic mitral regurgitation(NIMR) by real-time threedimensional transesophageal echocardiography (RT-3D-TEE),and provide a basis for surgical cardiac surgery.Methods 98 patients undergone RT-3D-TEE examination were enrolled in this study,and were divided into three groups:IMR group (n =43),NIMR group (n =33),and no mitral regurgitation group (control group,n =22).Full-volume 3D dynamic images of mitral annulus and valve were obtained.The images were off-line analyzed using Qlab 7.0 MVQ workstation,and the geometry indexes:area of leaflets (A3DE),area of anterior leaflet (A3DE Ant),area of posterior leaflet (A3DE Post),perimeter of annulus (C3D),anterolateral to posteromedial diameter of annulus (DAlPm),anterior to posterior diameter of annulus (DAP),annulus height (H),maximal prolapse height (HProl),maximal tenting height (HTent),volume of leaflet prolapse (Vprol),volume of the leaflets tent (Vtent),Aortic orifice to mitral plane angle (θ),angle of anterior leaflet (θAnt),non-planar angle of leaflets (θNPA),angle of posterior leaflet (θPost)and other mitral valve leaflets and annulus,were derived and statistically analyzed.Results Compared with the control group,significant increases of A3DE,A3DE Ant,DAP and θPost,and decreases of θ and θNPA were demonstrated in IMR group,the differences were statistically significant (P ＜ 0.05).Significant increases of A3DE,A3DE Ant,DAP,HProl,Vprol and θNPA,and decreases of θ,θAnt and θPost were explored in NIMR group,the differences were statistically significant (P ＜0.05).Compared with NIMR group,a reduction of A3DE,A3DE Ant,DAP,HProl and θNPA,and increases of θAnt and θPost were found in IMR group and the differences were statistically significant (P ＜0.05).Conclusions Both IMR group and NIMR group could lead to mitral annulus dilatation,leaflets area increase,and mitral annulus geometry change,the overall mitral annulus tends to flatten were more obvious in the NIMR group than those in IMR group.The prolapse is more prominent in NIMR group than those in IMR Group.The difference of mitral annulus geometry between IMR group and NIMR group indicates that the damage of the mitral leaflets and annulus might be more serious in NIMR group.

BACKGROUND:Distal femur is a predilection site for primary bone tumors, most of which are treated with salvage treatment. There are many reports on the early-stage, mid-term and prognosis of the distal femur tumor-type artificial knee joint prosthesis, but reports on long-term function and prognosis are less.
OBJECTIVE:To study the long-term prognosis and limb function after treatment with rotating-hinge knee prosthesis.
METHODS:Thirty-four patients with distal femoral bone tumors admitted to the Department of Orthopedics, the First Affiliated Hospital of Anhui Medical University between January 2000 and June 2008 were retrospectively analyzed, including 19 males and 15 females. Al patients were subjected to rotating hinge knee prosthesis replacement.
RESULTS AND CONCLUSION:The mean fol ow-up period was 62.4 months (range 11 to 126 months). At the final of fol ow-up, 23 patients were event-free alive and 11 patients were dead. Seven of 23 survival patients suffered from prosthesis related complications, including four cases of prosthesis revision and three cases of amputation. The event-free survival rate of 23 patients undergoing replacement of domestic tumor prosthesis around the knee was 67.6%in 5 years. The mean functional score of affected limb was 19.30 (7 to 27 points):excellent in 6 cases, good in 16, fine in 5 and poor in 2. The excellent-good rate was 75.9%. The clinical outcomes suggested that the satisfactory limb function and survival rate could be achieved with the application of domestic tumor prosthesis replacement for treatment of malignant bone tumors around the knee.

OBJECTIVE To investigate the productive rate of AmpC ?-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital. METHODS AmpC ?-lactamases and ESBLs were detected by the improved cefotaxime and ceftriaxone three-dimensional test. RESULTS The productive rate of AmpC ?-lactamases was 16.00%.Among them,the productive rate of AmpC ?-lactamases was only 8.84%.The Enterobacter cloacae,Serratia marcescens and Enterobacter aerogenes were easy to produce the enzymes(36.00%,31.25% and 28.00%).The productive rate of AmpC ?-lactamases and ESBLs at the same time was 7.16%. CONCLUSIONS The productive rate of the enzymes by the Gram-negative bacilli from the nosocomial infection is rather high.

Objective To explore the clinical characteristics,diagnosis,treatment,and prognosis of male breast cancer.Methods The clinical data of 38 cases of male breast cancer,who were treated in the two hospital during the past 10 years,were analyzed retrospectively.The diagnosis was mainly based on preoperative B-ultrasound,radiography with molybdenum target tube and fine needle aspiration.Among the 38 cases,radical mastectomy was conducted in 3 cases,modified radical mastectomy in 27 cases,simple mastectomy in 5 cases,and operation was refused in 3 cases.Postoperatively,radiotherapy was adopted in 4 cases,simple endocrinotherapy in 7 cases,radiotherapy plus chemotherapy in 9 cases,and chemotherapy plus endocrinotherapy in 8 cases.Results Median age at treatment was 58.5(53-82)years.TNM staging included stageⅠin 13 cases,stageⅡ in 19 cases,stageⅢ in 4 cases,and stageⅣ in 2 cases.Median follow-up was 73.8 months(2 months-10 years),and follow-up rate was 73.6%(28/38).During the follow-up,13 cases died including 8 cases died of local recurrence and metastasis,and 5 cases died of heart and brain disease.The 5-and 10-year overall survival rate was 71.6% and 55.3% respectively;5-and 10-year disease-specific survival of stageⅠ,Ⅱ was 92.6% and 78.9% respeoively;among 6 cases of stageⅢ,Ⅳ 4 were followed,and all 4 cases died with in 3 years.Conclusions Male breast cancer has a long course,poor prognosis and low survival rate.Combined therapy with modified radical mastectomy,as its basis,is the treatment of choice for male breast cancer.There is a certain correlation between the prognosis of male breast cancer and clinical stage of the disease.
