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 The purpose of the present study was to observe the muscle glucose metabolism by determining the changes in sarcolemma GLUT4 protein content and muscle AMPK activity in overtraining rats.Methods Twenty-seven SD rats were randomly divided into group A(sedentary),group B(underwent endurance exercise 60 minutes/day)and group C(underwent endurance exercise 120 minutes/day).Both exercise groups trained 6 days/wk for 9 weeks.Muscle glycogen,sarcolemma GLUT4 contents and muscle AMPK activity were determined after the 9-week training.Results Sarcolemma GLUT4 content and muscle AMPK activity increased,muscle glycogen contents tended to rise in group B as compared with that in group A.Sarcolemma GLUT4 content and muscle AMPK activity decreased,but muscle glycogen contents were equivalent in group C as compared with that in group B.Conclusion Muscle AMPK activity deceased,and the translocation of GLUT4 protein was inhibited in the overtraining rats.The results could not support a glycogen depletion hypothesis.

Present basic researches on hepatic stem cells have obtained great progress. It is believed that hepatic stem cells can differentiate into hepatic cells and biliary duct cells. Hepatic stem cells are isolated and cultured by two-step collagenase digestion method, density gradient centrifugation, centrifugal elutriation, fluorescent activation screening method and immunomagnetic beads screening method. Directional differentiation of hepatic stem cells is a complicated process, which is affected by exterior and interior cell factors under liver microenvironment where are beneficial to growth, differentiation and function of stem cells. Hepatocyte growth factor can promote the proliferation of hepatic stem cells, and accelerate the differentiation into mature hepatic cells. Transcription factor of hepatic cells play a crucial effect in regulating the differentiation of hepatic stem cells. Incomplete or abnormal differentiation of hepatic stem cells can be responsible for liver cancer. Hepatic stem cells are the potential carrier cells as a target gene for liver cancer.

Objective: To explore the Asian Resilience Scale’s preliminary revision, reliability and validity in college students of China. Methods: 646 students were investigated with the Asian Resilience Scale and the short form of NEO Five-Factor Inventory. Results: ①Three factors were extracted by exploratory factor analysis and explained 47.1% of variance. ②Confirmatory factor analysis showed good fit between the data and the construct of scale, ?2/df=2.36,RMSEA= 0.055,GFI=0.923,CFI=0.908,NNFI (TLI)=0.894. ③The Cronbach’s ? coefficients, split-half and retest reliability of the total scores were 0.865, 0.836 and 0.894 respectively. ④The total score of the Asian Resilience Scale was significantly negatively correlated with neuroticism and positively correlated with extraversion, openness to experience, agreeableness and conscientiousness. Conclusion: Reliability and validity of the Asian Resilience Scale’s revised Chinese version is corresponded with psychometric standard, and it could be used to assess the resilience of Chinese college students.

Objective:To observe the application value of autologous blood recycling machine in emergency surgery of ectopic pregnancy ruptures.Methods: Fifty patients with ectopic pregnancy ruptures performed intraoperative autologous blood transfusion by using the autologous blood recycling machine were chosen as research group, 46 cases of same or similar patients performed allogeneic blood transfusion as control group. In research group,perioperative HR, SBP, DBP, MAP, CVP and SpO2 were monitored, at the same time the blood indicators as WBC, Hb, HCT, FIB, PLT, PT, APTT were examined before, after and during the operation. Blood loss, blood collection and Blood transfusion status were recorded in two groups.Results: In research group, SBP, MAP and CVP increased significantly(after transfusion compared with before transfusion,t=-1.641,t=-1.230,t=-3.591 respectively,P<0.05; postoperative 24h compared with before transfusion,t=-1.870,t=-2.012,t=-3.205 respectively,P<0.05), HR decreased significantly(after transfusion compared with before transfusion,t=2.265,P<0.05; postoperative 24h compared with before transfusion,t=3.018,P<0.05); and WBC, Hb, HCT, PLT increased significantly (WBC, HB, HCT after transfusion compared with preoperative, t=-1.831,t=-1.653,t=-1.406 respectively,P<0.05; postoperative 24h WBC, HB, HCT, PLT compared with preoperative, t=-2.504,t=-1.910,t=-1.513,t=-2.310 respectively,P<0.05) after autologous blood transfusion and surgery. The volume of allogeneic blood transfusion volume, incidence of adverse reactions and costs of blood transfusion in research group were lower than those in control group(t=9.362,x2=4.22,t=5.405 respectively,P<0.05).Conclusion:The operation of blood recycling machine in emergency surgery of ectopic pregnancy ruptures timely manner is safe and effective is timely, safe and effective, can significantly reduce the adverse reactions and costs of blood transfusion, has important clinical application value.

Objective To survey the quantity of clinical practice of medical trainees in practice,analyze the status characteristics and main problems,and put preference for practice teaching administrative departments.Methods In June 2016,all students finishing internship in some military medical university were gathered and surveyed by the person in charge.Using self-made questionnaires,the students were asked to anonymously fill out the quantity of clinical practice by themselves respectively in different department and in various capacities.515 questionnaires were provided and 479 valid results were collected (93.0％).Using SPSS 16.0,the number of trainees in different genders,specialties and categories was analyzed by variance analysis and SNK test (22 comparison).Results The numbers of clinical practice as first assistants and second assistants in surgical medicine were the most,which were 5.70 and 5.29 in average,while those in specialty medicine were the least (al1＜2.85 in various capacities).The quantity of clinical practice in different specialties and sorts as second assistants in intemal medicine showed statistical significance (F=2.646,F=2.682;P=0.008,P=0.031) and SNK test showed that those in navy general practice medicine (5.81) and soldiers (4.59) operated more.The quantity of clinical practice in different specialties and sorts as first assistants in special medicine showed statistical significance (F=2.166,F=2.765;P=0.029,P=0.027) and SNK test showed that those specialties in pharmacy (3.33) and clinical medicine (3.22) and soldiers (3.03) operated more.Conclusion The quantity of clinical practice of medical trainees has characteristics with surgical medicine most and there is no links with genders.In the departments with more opportunities,the differences among different groups are not obvious,while in the less operating departments,the students with higher motivations operate more.Therefore,these departments should focus on mobilizing the enthusiasm of students.Besides,the quantity of clinical practice in medical trainees should be looked upon objectively and the operations should be done under the guide of the teachers and on the basis of considering the security of patients.
