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.

C-termini of proteins often play an important role in various biological processes, such as the transcription and translation from DNA to protein and also participating in various biological regulations. The determination of protein C-terminus is so crucial because it provides not only distinct functional annotation, but also a way to monitor the proteolysis-modified proteins. Based on the biological mass spectrometry, a series of novel methods and technologies were developed both for qualitative and quantitative analyses of protein C-terminus. These methods or technologies can be applied to accurate and effective protein C-terminus profiling, including the sequences and quantitative information of C-termini, which reveals the biological function of C-termini in life's activities and provides a better understanding of the degradation of mature proteins. Combined with our research, this review highlights the improvements in C-terminal proteomics study in the past decades, including the methodologies for recognition and identification of C-terminus, as well as the enrichment strategies for protein C-terminus.

Objective To investigate the factor that related to neoplasm from the clinicopathologic character of gallbladder polyps, and identify the reciprocal effectiveness of these factors. Method Three hundred and forty-seven patients who were underwent operation with gallbladder polypoid lesions were reviewed. Results Logistic regression analysis showed, only 5 parameters were significant for the prediction of neoplastic lesions, including age of the patient (P =0.015), the number of polyps (P=0.018), the maximal diameter (P=0.000), echo property (P=0.000), as well as the position of polyps (P=0.030),of which the maximal diameter was the best one to predict the neoplasm polyps. Further analysis with HOC curve showed that 0.925 cm, the diameter of polyps, was the critical point to calculate the polyp was neoplasm or not. Conclusions Age of the patient , the number of polyps , the maximaldiameter, the position of polyps, and echo property are independent factors in predicting gallbladder neoplastic lesions. The size of the polyps is the most significant one among the factors to predict gallbladder neoplasm with its critical point of 0.925 cm.

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 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.

According to the records in Neijing (Internal Classic), this article discusses the relationship during the connotative evolution of mai (vessel) and jing (meridian) in the three aspects, named mai (vessels), the evolution from mai (vessel) to jing (meridian), and the connotation replacement of jing (meridian) with mai (vessel). The study results show that the connotation of Jingmai is originated from mai (vessel), but more enriched, which cannot be confused with each other. The recognition on the connotation of jingmai from mai (vessel) to jing (meridian) is the process of TCM understanding from concretization to abstraction, and from the entity to the concept. Jing (meridian) represents the law on the longitudinal and invariable running course of meridian, differenti from the perspective in western medicine in human body. This law results from the naive observation and is based on the rational summary and thinking, and it stands up the approval from practice. The description of jing (meridian) as mai (vessel) is just the superficial description of this term. In fact, its concept infers to the connotation of meridian.

OBJECTIVETo explor the curative effect of double pedicle sliding skin flap for correction of cryptotia.

METHODSFrom January 2011 to October 2014, 7 cases with cryptotia (12 ears) were treated. We designed a double pedicle sliding skin flap above the helix. The flap was slided downward to form a new auriculocephalic sulcus. The other wound was covered by skin graft.

RESULTSAll wounds healed very well with no complication. The follow-up period ranged from 3 months to 1 year, with an average of (5.67 ± 3.38) months. The ear had stable appearance with no recurrence. The result was satisfactory.

CONCLUSIONSThe method is simple with reliable flap survival rates. The new auriculocephalic sulcus is stable and resistant. It's a good choice for correction of cryptotia.

BACKGROUND:Precancerous lesions are a long-term development process in which many factors are involved. Bone marrow mesenchymal stem cel s can repair tissue injury. OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cel transplantation on gastric precancerous lesions in the rats. METHODS:Thirty-six Wistar rats were randomly divided into control group, model group and transplantation group. Animal models of gastric precancerous lesions were established in the model and transplantation groups. Rats in the transplantation group were given 1 mL of CM-dil-labeled bone marrow mesenchymal stem cel s (3×106 cel s) via the tail vein, once a week, total y three times. Rats in the model and control group were subjected to the tail vein injection of the same volume of normal saline. Then, rats were sacrificed 1 week after final injection, and pathohistological changes in rat gastric tissue sections were observed. The expression of vascular endothelial growth factor in the gastric mucosa and levels of serum cytokines were detected. RESULTS AND CONCLUSION:The severity of gastric mucosal injury in the transplantation group was lighter than that of the model group. The expression of vascular endothelial growth factor was significantly higher in the transplantation group compared with the model and control groups (P<0.05). The levels of serum interleukin-17 and interferon-γwere significantly higher in the model group than the transplantation group fol owed by the control group (both P<0.05). Therefore, bone marrow mesenchymal stem cel s can increase vascular permeability, reduce inflammation, block or ease the occurrence of precancerous lesions by up-regulating the expression of vascular endothelial growth factor in the gastric mucosa lesions and reducing the expression of interleukin-17 and interferon-γ.

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.
