1.Research advancement on triple negative breast cancer
Journal of International Oncology 2010;37(5):371-375
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.
2.New perspectives of glycogen storage disease
International Journal of Pediatrics 2011;38(1):62-65
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.
3.Magnetic compression anastomosis: a promising technique in the further development of minimal invasive surgery
Chinese Journal of Hepatobiliary Surgery 2011;17(8):621-623
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.

Chinese Journal of Medical Education Research 2011;10(1):36-39
The famous Abraham Flexner's 1910 report to the Carnegie Foundation launched the modern medical educmion.The report'S focus on the medical education standards and the curricula frameworks was laudable and appropriate.At the centennial of this report.we were still able to get a lot of inspiration and the direction of development and reforms of medical education by reviewing Flexner'd Report.
5.Relationship between body mass index and postopoperative liver function prognosis of patients with hepatocarcinoma
International Journal of Surgery 2011;38(4):238-240
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.
6.Study on n-Hexane-induced Lipid Peroxidative Injuries in Rats
Journal of Environment and Health 2001;18(2):86-88
Objective To study the mechanism of toxicity of hexane. Methods SD rats inhaled 15 g/ma n-hexane statically for 8 hours. Results The levels of GSH in whole blood of rats declined significantly (t-test,P<0. 01). The levels of MDA in serum of rats revealed increasing trend but without statistical significance (t-test,P>0. 05). The activities of SOD and GSH-Px in liver of rats decreased significantly (t-test,P<0.01). Conclusion n-Hexane could induce or enhance the reaction of oxygen free radical in organism,and result in damages of lipid peroxidation,which might be one of the mechanisms of the toxicity of alkane.
7.Expression of p16 and CDK4 in human lung carcinoma
China Oncology 2001;11(2):123-124
Purpose:To study the expressions of p16 and CDK4 in human lung carcinoma. Methods:By using S-P immunohistochemical methods, the expressions of p16 and CDK4 in 62 cases of human lung carcnoma were studied. Results:The postive expressions for p16 and CDK4 protein were 58.1% and 48.4% respectively. A significant correlation was found between CDK4 overexpression and lymph node metastasis (P<0.01). A significant correlation between the under expression of p16 and overexpression of CDK4 was found.Conclusions:The results suggested that CDK4 overexpression plays an important role in metastasis of lung carcinoma.
8.Effects of carbon monoxide poisoning on the long-term cognitive function in elderly patients
Chinese Journal of Geriatrics 2012;(12):1060-1062
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.

10.The pituitary-bone axis in bone metabolism
Chinese Journal of Endocrinology and Metabolism 2011;27(2):184-188
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.
