Operation is one of the important ways in breast cancer treatment.With the deep basic medical research,new theory,new concept and new technology improve the operation therapy in breast cancer in more scientific and rational way Breast-conserving therapy and sentinel lymph node bipsy (SLNB) are applied,and the neoadjuvant chemotherapy make breast-conserving therapy more feasible.The progress of operation therapy in breast cancer make it critical to emphasize the individualized treatment in breast cancer.

Objective To analyze the related factors of local recurrence in patients with rectal cancer after Dixon operation. Methods A retrospective analysis of clinical data of 100 patients from September 2005 to September 2007 in our hospital by TME standard surgicai treatment of low rectal cancer was carried out. Results Of 100 patients, the pre-sacral recurrence rate was 10. 0%, with gender, age, tumor size, tunor invasion lumen circumference,depth of invasion,lymph node metastasis and Duke's stage has nothing to do with the gross type,histological type and lumen,peritoneal tumor cell shedding,and as an independent prognostic factor. Of 90 patients without local recurrence,the 5-year survival rate was 76. 0% ,haff of the survival of 62 months;10 cases of local recurrence,5-year survival rate was 5. 0%, half of the survival of 24 months, suggested that local recurrence in patients influenced the prognosis. Conclusion The low local recurrence of rectal cancer related factors were gross type,histological type and the intestine, peritoneal tumor cells shed, seriously affect the prognosis of patients with local recurrence.

As human beings ascend to high altitude, a number of reactions may occur against hypoxic injuries. These hypoxic responses are related to intake, transportation and utility of the oxygen. As a crucial subcellular organelle of oxygen utility, mitochondrion is a central link of high altitude acclimatization, adaptation and mountain sicknesses. In this review, we discussed the recent advances in researches on hypoxic mitochondrial responses at high altitude.

This article was aimed to explore the method of traditional Chinese medicine (TCM) health maintenance knowledge base building. TCM health maintenance knowledge classification method was studied under the guidance of TCM health maintenance classification system to construct a special literature database to store TCM health maintenance knowledge. Based on TCM literature resources, TCM health maintenance knowledge service platform was designed and developed for the static display and dynamic query support of TCM health maintenance knowledge. The content of knowledge base will be accessed to the whole society. The results showed that the construction method can be a system arrangement and modern interpretation of TCM health maintenance knowledge, in order to support TCM health maintenance knowledge base and its update and service system. It was concluded that under the guidance of TCM theories, the construction of TCM health maintenance knowledge base will realize the health maintenance knowledge-sharing and service requirement of TCM.

Based on the investigation and analysis of industry dynamics of health maintenance Applications (APP) of Traditional Chinese Medicine (TCM),the paper designs and develops health maintenance APP of TCM,and describes its architecture,operating principle,functions,innovativeness,applicability scope,etc.

Objective To investigate and compare the clinical values of serum procalcitonin (PCT)and high sensitivity C-reac-tive protein (hs-CRP)levels for predicting the blood culture positivity in the patients with sepsis.Methods 132 adult patients with sepsis were enrolled in this study.Blood cultures were performed before the antibacterial therapy.The white blood cell (WBC) count,absolute neutrophil count(ANC),levels of PCT and hs-CRP were determined.The application value of PCT and hs-CRP for predicting the positive blood culture results were evaluated.Results The median serum PCT levels in the blood culture positive group and the blood culture negative group were 7.92 ng/mL and 0.95 ng/mL respectively,the difference had statistical signifi-cance(P <0.01).The receiver operating characteristic (ROC)curves showed that PCT had a higher predictive accuracy for blood culture positivity compared with hs-CRP,the area under the curve (AUC)was 0.810(P =0.001)and 0.690(P =0.274),respec-tively.The combined detection of PCT and hs-CRP for predicting the blood culture positive results was similar to the performance of PCT alone,AUC as 0.885 (P =0.001 ).The median cut point of PCT was 0.91 ng/mL,the sensitivity of PCT for predicting blood culture positivity was 90%.This sensitivity remained unchanged when PCT cut point was1.14ng/mL.Using the PCT cut points of 0.91 and 1.14 enabled reducing the submitted blood cultures by 51% and 56% respectively.Conclusion Compared with hs-CRP,serum PCT level could better predict the blood culture positivity in the patients with sepsis.

OBJECTIVETo explore correlation between lung and large intestine and the two meridians under pathological condition in the view of meridian theory.

METHODSNinety-six cases of bronchial asthma were applied palpation at the running course of 12 regular meridians under the elbow and knees and back-shu points. And abnormal reactions were recorded, the affected meridians and back-shu points were discovered.

RESULTSThe abnormal reactions most frequently appeared on the Lung Meridian, followed by the Large Intestine Meridian, the Spleen Meridian, the Liver Meridian, the Stomach Meridian and the Triple Energizer Meridian. And the unusual reaction of the back-shu points most frequently appeared on Feishu (BL 13), and Dachangshu (BL 25) and Pishu (BL 21) followed as the next two.

CONCLUSIONThe existence of correlation between the Lung Meridian and the Large Intestine Meridians under pathological condition can be proved through meridian and acupoint palpation on bronchial asthma patients.

AIMTo investigate whether free fatty acid impair insulin signaling proteins to inhibit insulin action in rat islet cells.

METHODSAfter rat islet cells were incubated with palmitate (0.25 mmol/L) or oleate (0.125 mmol/L) for 12 hours, 24 hours and 36 hours, western bolt was used to assess the protein abundance of cPKCalpha, Grb2 and FERK2.

RESULTSThe protein content of cPKCalpha were significantly upregulated and the protein abundance of Grb2 and ERK2 was decreased comparing with control in rat islet cells after incubated with free fatty acids.

CONCLUSIONSFree fatty acids may inhibit insulin activity in rat islet cells through up-regulating the expression of cPKCalpha or down-regulating the expression of Grb2 and ERK2.
