Triple negative breast cancer(TNBC) is defined by the lack of estrogen receptor (ER) , progesterone receptor (PR) and human epidermal growth factor receptor-2 ( Her-2) expression. It is a subtype of tumor with distinct clinical and pathologic features and lacks effective targeted therapies. It is non - sensitive to endocrine therapy and targeted therapy drug herceptin, leaving chemotherapy as the mainstay of treatment The feature and the treatment of TNBC is the hotspot of resent research.

Glycogen storage diseases (GSD) are a group of inherited disorders characterized by enzyme defects that affect the glycogen metabolism. Hypoglycemia, hepatomegaly, splenomegaly and growth retardation are the main clinical manifestations. The enzymes affecting glycogen synthesis and degradation are varied.Consequently, the clinical manifestations are different because of different enzyme defection. Most patients treated regularly can obtain the normal growth and grow to adults, but still can be accompanied long-term complications by adulthood. Now some scientists find new modified cornstarch is superior to standard therapy in maintaining blood glucose levels. Gene therapy is still in the experimental animals.

Objective To investigate the relationship between body mass index(BMI) and the outcomes of liver function of patients with hepatocarcinoma after surgery. Methods We divided the patients into three groups: normal, overweight and obese groups based on BMI, then we recorded their preoperative and the postoperative liver functions: albumin, total bilirubin, alanine aminotrasferase(ALT), aspertate aminotransferase (AST), alkaline phosphatase(ALP), γ-glutamyltranoferase(γ-GGT), triglycerides(TG), total cholesterol (TC), high density lipoprotein(HDL) and low density lipoprotein(LDL). Results The mean values of ALT change between the preoperative and the postoperative were (14.9 ± 1.98) U/L, (15.4 ± 2.27) U/L,(22.2±1.32) U/L; Mean values of γ-GGT change were(16.2 ± 1.33) U/L, (18.7 ±0. 97) U/L,(22.3 ± 1.27) U/L; mean values of TG change were (0. 18 ± 0. 44) mg/dL, (0. 21 ± 0.08) mg/dL,(0.25 ± 0.03) mg/dL. Compared with the results of control groups, there were no significant differences of recovery of liver functions between normal and overweight groups(P ＞ 0. 05), but the obese group' s recovery of liver functions did lag behind the normal group (P ＜ 0.05). It is showed that the obese group' s shared same recovery of albumin, total bilirubin, AST, ALP, TC, HDL and LDL. The difference was significant between the normal and obese groups in terms of recovery of ALT, γ-GGT, TG(P ＜ 0. 05). Conclusion BMI is associated with the recovery of liver function of patients with hepatocarcinoma, the obese patients have poor prognosis of recovery of liver function.

Magnetic compression anastomosis (MCA)involves the use of two rare-earth magnets that attract to each other transmurally between two internal organs, resulting in compression and subsequent fistula formation to create a nonsurgical enteric, vascular, or biliary anastomosis with therapeutic aims. The magnetic vascular coupler allows a sutureless anastomoses between arteries and veins by using interventional radiological techniques. The MCA technique significantly reduces ischemic time during anastomosis, and has the advantages of low invasiveness and simplicity. It is a rather effective method for recanalizing between various hollow viscera, creating anastomosis such as gastrojejunostomy, choledochojejunostomy, or choledochoduodenostomy.Furthermore, this novel technique is considered to be a feasible and alternative reconstructive method for patients who develop significant bile duct complications following hepaticojejunostomy and living donor liver transplantation. MCA is a promising and novel technique in the further development of minimal invasive surgery.

Recent studies have shown that pituitary hormones, including thyroid stimulating hormone (TSH), follicle stimulating hormone(FSH), adrenocorticotropic hormone(ACTH), and oxytocin(OT)may actually bypass their target endocrine organs and affect the skeleton directly. Therefore, a new conception, pituitary-bone axis is proposed. This breakthrough sheds a new light on the function of pituitary hormones and the pathogenesis of osteoporosis associated with hyperthyroidism, menopause or pregnancy, and even osteonecrosis after using glucocorticoids. In addition, it is conducive to give the reference guidance for clinical treatment of metabolic bone diseases and new drug development.

Objective To explore the main factors of hypokalemia in the patients with acute myocardial infarction after PCI.Method The clinical data of ninety-six patients with myocardial infarction after PCI were analyzed to look into the reasons for hypokalemia.Results Fifty-seven patients contracted hypokalemia,with a rate of 59.4%.The complication was cured by dietetic supplementation of potassium,oral supplementation of potassium,and potassium supplementation by atomization inhalation and intravenous infusion.The reasons for hypokelemia included inadequate input,over-ejectment,abnormal distribution of potassium and use of contrast agent.Conclusions Patients with myocardial infarction after PCI are more susceptible to hypokalemia.Therefore,it is a need to correct hypokelemia by means of potassium supplementation.

Objective To investigate the effect of COX-2 in the DSS-induced UC mouse model and the effects of probiotics in the pathogenesis of UC. Methods DSS-induced UC mouse model was used in the study. A total of 60 mice were divided into 6 groups (Blank control group, DSS model group, Saline group, SASP group, Lactovacillus group and Bifidobactefia group). After 8 days, all mice were sacrificed. Histological injury score and pathological change and COX-2 in mucous of colon membrane were evaluated. Results The stages and histological changes were obviously improved and the expression of COX-2 in the colonic mueosa of mouse with UC was decreased when using probiotics and SASP. Conclusions Lactobacillns and Bifidobacterla can decrease the expression of COX-2 in the colonic mucosa of mouse with UC. The effect has no difference between SASP and probiotic group.

BACKGROUND:For reducing the stress shielding, a lot of the schemes have adopted, and there is no great improvement although via the trial and the application for several ten years. It comes from a root which is the combination by thigh bone (abbreviation of the bone) and metal ic handle (abbreviation of the handle) which causes the serious problems of absorption of bone quality, and this kind of stress shielding effect is produced by abnormal stress and abnormal strain, and affected by various factors, so there is no effective and applicable method to solve this problem.
OBJECTIVE:To select the primary porous layer scheme as the subject of the study and entirely change the appearance and inherent quality as the metal ic handle that cannot transmit the stress is the key to eliminate the stress shielding;making the senior porous layer with the effective measure is the basis to eliminate stress shedding and can solve the disaster and partial inferior position aroused by the primary porous layer.
METHODS:The cobalt-chromium-molybdenum al oy smal metal ic spherules with equal diameter were used to manufacture the senior porous layer structure. The structural member employed in the thigh bone could separate the handle from the bone. This structural member welded on the plane of bone neck could fix the handle with calcar osteotomy surface. And these structural members had an ability to eliminate al the stress shieldings on the artificial hip joint surface.
RESULTS AND CONCLUSION:The senior porous layer was made with cobalt-chromium-molybdenum al oy smal metal ic spherules with the same diameter (1.00-1.29 mm), and the surface of the porous layer was plated with high property of medium layer al oy and arranged orderly and inseparable, and then connected with active diffusion welding technology. The diameter of al the holes was 155-200μm and distributed evenly which was benefit for the bone unit to grew. The al oying of metal materials, ceramic of al oy surface and control ing of size and number of wear particles can solve the bone dissolution of the surrounding porous layer of bone, metal dissolution as wel as its pure cobalt and chromium particle toxicity, cancerization and leukemia. A stipulation of theoretical basis was to eliminate the handle rigidity firstly that could made the separation of handle from the bone became the premise for eliminating the stress shielding. The calcar osteotomy surface grew into the pores of the structural member welded on plane of bone neck could fix the handle, and that was the basis for eliminating the stress shielding. The common roles can eliminate the stress shielding in thigh bone, and the stress shielding on acetabulum is easily to eliminate.

Objective To investigate the effects of carbon monoxide poisoning on the long-term cognition in elderly patients.Methods Totally 53 patients with carbon monoxide poisoning and 51 healthy persons at our Hospital from June 2005 to June 2008 were enrolled.Mini-mental state examination(MMSE) and activities of daily living(ADL) scale were utilized to evaluale the life quality of the elderly patients through a cross-sectional study on July 2011.Results MMSE score showed that the attention calculation score,delayed recall score,and total score were higher in control group (4.9±0.4,2.9±1.0,28.3±2.3,respectively) than in carbon monoxide poisoning group (4.5±0.8,2.6±0.6,25.5±3.5,respectively) (t＝3.138,3.607,4.802,all P＜0.05).ADL score of carbon monoxide poisoning group was 26.7±7.3,and that of the control group was 2.04±7.6 (t＝1.827,P＞0.05).Conclusions Elderly patients with acute carbon monoxide poisoning may cause long-term cognitive impairment with decreasing attention calculation and delayed recall.
