Objective: To detect the correlation of the expression of c-erbB-2, p53, PCNA and bcl-2 with the biological behavior of breast cancer. Methods: We used immunohistochemistry to detect the expression of c-erbB-2, p53, PCNA and bcl-2 in 56 breast cancer patients. Results: The expression of c-erbB-2 was 41.1% and was negatively correlated with histological classification but was not correlated with age, clinical stage, ER, or PR. The expression of p53 was 48.2% and was positively related with ER and PR but was negatively correlated with clinical stage and pathological type. The expression of bcl-2 was 50.0% and was negatively correlated with histological classification, ER and PR and was positively correlated with clinical stage and pathological type. PCNA was highly expressed in the 56 cases. Conclusion: We should combine the detection of c-erbB-2, p53, PCNA and bcl-2 with the evaluation of clinical stage, histological degree and pathological type in order to improve the prognostic estimation of breast cancer.

Objective To observe the clinical effect of preoperative acupuncture on hypercoagulability of elderly patients with intertrochanteric fracture. Methods Sixty elderly patients with intertrochanteric fracture were evenly randomized into control group and acupuncture group. Both groups were treated with external application of Shangke Huangshui gauze on the affected region, and additionally the acupuncture group was treated with acupuncture on bilateral acupoints of Huantiao, Xuehai, Liangqiu, Zusanli, Sanyinjiao, and Taichong. The treatment for the two groups was performed from the hospitalized day to the day before operation. The parameters of thrombelastograph (TEG) before and after treatment and the occurrence of deep venous thrombosis (DVT) were observed . Results After treatment, the difference of TEG parameters of the control group was insignificant as compared with those before treatment (P>0.05). In the acupuncture group, the coagulation reaction time(R) and clot formation time(K) were significantly prolonged(P < 0.05) , and coagulation angle alpha (α), maximal amplitude (MA)of thrombus and clot strength (G) were significantly decreased (P <0.05), the effect being superior to that in the control group(P<0.05). Till the day before operation , 3 cases from the control group suffered from DVT, but none of acupuncture group suffered from DVT, the difference between the two groups being insignificant(P > 0.05). Conclusion Preoperative application of acupuncture can improve the hypercoagulability of elderly patients after hip fracture.

Acute respiratory distress syndrome (ARDS) is a common clinical critical condition of the respiratory system, with a high fatality rate and lack of effective drug treatment, hence it is a global medical problem to be solved urgently. Recently, with the in-depth research on extracellular vesicles (EVs) at home and abroad, more and more evidences suggest that EVs play a critical role in the initiation, development and progression of ARDS and have potential clinical application value. The role of different cells derived EVs in ARDS will be reviewed in this paper.

Objective Postoperative pulmonary vein stenosis(PPVS) is a severe complication after total anomalous pulmonary venous connection (TAPVC) repair,and represents a significant surgical challenge with a high recurrence rate and poor prognosis.This study was performed to analysis the morphological patterns of pulmonary vein stenosis after TAPVC,and to demonstrate the relationships between the pathological patterns with their clinical manifestations,pathogenesis,surgical options and their prognosis.Methods Between March,2004 to September,2011,11 consecutive patients with PPVS underwent reoperations.Supracardiac type in 5 cases,intracardiac type in 3 cases,mixed type in 1 case,single ventricle associated with supracardiac type in 1 case and infracardiac type in 1 cases.The age was 23 days to 28 months,body weight at the first operation was 5-19 kg,the median weight (10.7 ± 5.1) kg.The age at reoperation was 4 months to 6 years,the interval between the first and second operation was 82 days to 5 years.Morphological patterns of PPVS was classified into 4 types based on the preoperative imaging examinations and surgical findings:(1) anastomic stenosis (type Ⅰ),(2) ostial stenosis of individual pulmonary vein (type Ⅱ),(3) segemental stenosis of individual pulmonary vein (type Ⅲ),(4) complete occulsion of individual pulmonary vein (type Ⅳ).One or more pathological patterns may exit in one patient,and may involved one or more individual pulmonary veins.Fibrous resection in 1 case,patch augmentation in 3 cases,individual pulmonary endarterectomy in 7 cases and sutureless technique in 5 cases.Cardiopulmonary bypass with moderate hypothermia were used in 8 cases,with deep hypothermia and circulatory arrest in 3 cases.Results Type Ⅰ in 2 cases,type Ⅱ in 2 cases,type Ⅰ and type Ⅱ in 1 cases,type Ⅰ,type Ⅱ and type Ⅲ in 1 case,type Ⅱ and Ⅲ in 2 cases,type Ⅱ and Ⅳ in 1 case and type Ⅳ in 2 cases were found in our series.There was no early mortality,I case with residual anastomic obstruction and 2 cases with individual pulmonary vein obstruction.One patient died 17 monthes after reoperation,and the intermediate mortality was 10％.Reoperation was done in 1 case for recurrent pulmonary vein obstruction.Two patients need ViagTa or Bosentan for long time.The others did well during follow-up.Conclusion PPVS is a kind of progressive disease.The morphological patterns of PPVS are related to their clinical presentations and its pathogenesis,and are very important to make surgical decisions and pridict the patient's prognosis.

Objective To evaluate the effect of neoadjuvant chemotherapy on lymph node micrometastasis and DC cell number in stage Ⅲ gastric cancer patients.Methods Lymph node micrometastases in pathologically negative lymph nodes from 76 stage Ⅲ gastric cancer patients [56 cases with neoadjavant chemotherapy (NCT) and 20 cases without],were assessed by cytokeratin-20 antibody.Dendritic cells (DC) in HE positive lymph nodes,HE negatives near tumor foci and HE negatives far foci were assessed by CD83 antibody respectively.Patients were divided into four groups:group 0 (20 cases without NCT),group 2 (two courses of NCT in 29 patients),group 3 (three courses of NCT in 16 patients),group 4 (four courses of NCT in 11 patients).Results In NCT group there were two patients with micrometastases (2/56).All the patients were with micrometastases in control group (20/20).Difference was statistically significant (P =0.000).In HE-positive lymph node group:the number of CD83-positive DC in 2 times group,3 times group,and 4 times group when compared with no chemotherapy group were statistically significant (P20 =0.001,P30 =0.000,P40 =0.000).In HE-negative lymph node near foci group:the number of CD83-positive DC in 3 times group,and 4 times group compared with 0 group were statistically significant increased (P30 =0.001,P40 =0.001).In HE-negative lymph node far foci group:the number of 4 times group was significantly higher than 0,2 and 3 group (P40 =0.000,P42 =0.000,P43 =0.001).Conclusions Neoadjuvant chemotherapy is effective in the prevention of lymph node micrometastases in stage Ⅲ gastric carcinoma and it increases the number of mature dendritic cells in lymph nodes.

Objective To observe the TCM syndromes of acute exacerbation of chronic obstructive pulmonary disease (COPD) with malnutrition. Methods TCM Syndromes Questionnaire of Acute Exacerbation of COPD was formulated with TCM clinical epidemiology methods. Totally 220 cases of hospitalized patients met the inclusion criteria were divided into two groups, 120 cases of malnutrition and 100 cases of non-malnutrition. The clinical data were observed and syndrome elements of malnutrition group and non-malnutrition group were analyzed to discuss the rule of syndromes in acute exacerbation period. Results In addition to respiratory system, the frenquency of symptoms such as weight loss, shortness of breath, easy cold, aversion to wind and cold, poor appetite, abdominal distension, constipation, belching, dizziness and tinnitus, tooth loose and hair loss, soreness and weakness of waist and knees significantly increased in COPD with malnutrition, mainly involving in syndromes of spleen deficiency and incoordination between spleen and stomach. In patients with acute exacerbation of malnutrition COPD, the single syndromes were 36 cases (30%), the composite syndromes were 84 cases (70%). The simple excess syndromes were 38 cases (31.67%), the simple deficiency syndromes were 23 cases (19.17%), and the intermingled deficiency and excess syndromes were 59 cases (49.17%). Conclusion Patients with acute exacerbation of COPD with malnutrition are mainly composite syndromes and the intermingled deficiency and excess syndromes. Spleen deficiency and incoordination between spleen and stomach may be the important pathogenesis of COPD with malnutrition.

Objective: To explore the clinical efficacy of a new drug for acute coronary syndrome (ACS), ticagrelor in treating the patients with acute ST-segment elevation myocardial infarction (STEMI), and to compare the effect between ticagrelor and clopidogrel in order to obtain the prospective information of ticagrelor in clinical practice.
Methods: A total of 307 STEMI patients were divided into 2 groups, Treatment group, the patients received ticagrelor with aspirin, n=157 and Control group, the patients received clopidogrel with aspirin, n=150. With a period of treatment, the major adverse cardiac events (MACE), rate of thrombosis re-formation and routine blood test result were compared between 2 groups.
Results: Treatment group presented the better LVDD, LVEF, platelet level and ST-segment recovery than those in Control group, P<0.05 or P<0.01. Treatment group showed slightly higher rate of side effect such as dififcult breathing and bleeding, while those reaction did not affect the treatment or special management for the patients.
Conclusion: The clinical effect of ticagrelor is similar to clopidogre for improving the platelet level and cardiac function in STEMI patients, while the clinical advantage reported in abroad should be further studied.

Objective To analyze the clincopathological features and prognosis of 77 colorectal cancer patients with synchronous liver metastases after resection of the primary tumors.Methods Seventy seven colorec-tal cancer patients with synchronous liver metastases who underwent resection of the primary tumors and patholog-ical confirmed were enrolled in this retrospective study.The clincopathological features and prognosis were ana-lyzed.Kaplan-Meier method was used to analyze survival rate.The differences between survival curves were cal-culated by Log-rank test.Results The analysis showed that sex,tumor differentiation and TNM stage were as-sociated with prognosis(P<0.05).The analyses demonstrated no differences in age,primary tumor site,treat-ment,number of liver metastases and extrahepatic metastasis(P>0.05).There was a significant correlation be-tween CEA,CA19-9 level and gender,tumor differentiation and TNM stage(P<0.001)and the corresponding surgical procedure and TNM stage(P<0.05).Conclusion The analysis show that male,the low differentiation and stageⅢare poor prognosis factors.
