Most deaths of breast cancer patients may be caused by the development of metastases. The latest research suggest that some miRNAs regulated gene expressions related with breast cancer metastasis at post-transcriptional level, which was closely related to invasion and metastasis of breast cancer. This review mainly dicussed the miRNA involved in regulation of invasion and metastasis of breast cancer and their mo-lecular mechanisms.

Patients who have received coronary artery interventional therapy exhibit visible anxiety and depression, which is closely related to prognosis and life quality. Therefore, for coronary artery stent patients,exception of anticoagulation and antihyperlipedemic drugs, psychological support, cognition therapy and distorted behavior rectification should be applied. The medication of anti-anxiety or depression is of great importance in ameliorate mental state, relieve mental load, as well as enhance prognosis of patients.

Conventional therapy was given to 260 cases of advanced stage of cancer of colon during the period of 1975 - 1988. Radical operation, palliative resection or changing bowel passage were selected according to the condition of the lesions. Post operative chemo -therapy with integrated Chinese and western medicine were given, or with radiotherapy in some of the cases. Results showed that the 5- year survival rates of II, III, IV stages were 80. 5%, 56. 12%, 21. 73% respectively, the mean 5 -year survival rate being 52. 78%, 45 cases with liver metastasis were also treated with integrated medicine with a 5 - year surivial rate of 22. 2%. The above figures of therapeutic effect and survival rates were all superior to that in cases treated by western medicine alone as reported by domestic exponent units.

Setting up a system wherein general practitioners play the role of the “goalkeeper” in the delivery of community health services may guide the rational flow of health resources from the upper to the basic levels, match the allocation of health resources to the demands, improve the effectiveness of health resources allocation, reinforce preventive strategies, and construct a highly efficient and economic health services system. By introducing the role of general practitioners in Britain, Australia and the United States, the paper aims to draw some enlightenment which will contribute to the establishment of such a system in China in the following aspects: ①perfecting the system of national supporting policies; ② making a good analysis of the parties interested; ③improving the makeup of the medical insurance system; ④accepting useful suggestions from relevant learned societies; ⑤ training general practitioners;⑥ establishing standards for the cooperation between general practitioners and specialists.

Objective To explore the re-treatment approach for nonsmall-cell lung cancer(NSCLC)in clinic with therapeutic alliance of cryotherapy and interventional chemotherapy. Methods Sixty two patients with uncontrolled NSCLC after common radiotherapy and(or)chemotherapy were re-treated with therapeutic alliance of cryotherapy and interventional chemotherapy, and their serum tumor markers of NSE, CEA, CY21-1 and the value(I.S%,I.O.D%)of correlative protein in nucleolus region-Ag-NORs were tested before and after the re-treatment. Meanwhile, patients' one year survival and therapeutic effect to NSCLC were recorded during the follow up. Results After the re-treatment, distinguished decline of the serum tumor markers was observed(P

Objective To study the effects of QRS-complex duration of patients with chronic left heart failure on their in-hospital prognosis. Methods Total 174 patients admitted for chronic left heart failure ( New York Heart Association class 3 and 4 ) from January 2014 to June 2015 were enrolled the study. They were divided into two groups according to the QRS duration at admission:normal QRS duration group (QRS ≤120 ms, n=145) and prolonged QRS group (QRS ﹥120 ms, n=29). The differences of clinical characteristics and incidences of exacerbated left heart failure, fatal arrhythmias and cardiac death during hospitalization were compared between the two groups. The influences of QRS duration on in-hospital adverse cardiovascular events was analyzed by logistic regression. Resu1ts The proportion of males (75. 9% vs. 24. 1%, P=0. 001), plasma B-type natriuretic peptide (BNP) (7. 1 ± 0. 8 vs. 6. 6 ± 1. 0, P=0. 02), left ventricular end diastolic diameter (LVEDd) [(60. 7 ± 9. 9)mm vs. (53. 5 ± 10. 8)mm, P=0.001], left ventricular end systolic diameter (LVESd) [(49.1 ±13.3)mm vs. (39.7 ±13.0)mm, P﹤0. 001], and the incidence of exacerbated left heart failure (20. 7% vs. 4. 8%, P = 0. 003), fatal arrhythmias (55. 2% vs. 21. 4%, P ﹤0. 001) and cardiac death (6. 9% vs. 0. 7%, P =0. 019) during hospitalization were significantly higher in the prolonged QRS group than in the normal QRS group. Left ventricular ejection fraction( LVEF) in the prolonged QRS group was significantly lower than in the normal QRS group (39. 6% ±17. 3% vs. 50. 5% ± 17. 3%, P =0. 002). Heart rates [(92. 4 ± 21. 4)bpm vs. (81. 6 ± 19. 9)bpm,P=0. 035], plasma BNP(7. 2 ± 0. 8 vs. 6. 7 ± 1. 0, P=0. 029), LVEDd(63. 5 ± 9. 1 vs. 57. 9 ± 9. 1, P=0. 015), LVESd (52. 9 ± 12. 2 vs. 44. 3 ± 11. 8, P=0. 005), incidences of left heart failure deterioration (18. 2% vs. 3. 2%, P=0. 018), fatal arrhythmias (63. 6% vs. 36. 5%, P=0. 027) and cardiac death ( 9. 1% vs. 0%, P=0. 015 ) during hospitalization among male patients in the prolonged QRS group were significantly higher than those in the normal QRS group, but LVEF ( 35. 0% ± 15. 3%vs. 47. 1% ± 16. 2%, P =0. 003 ) was on the opposite. The incidence of left heart failure deterioration among female patients in the prolonged QRS group was higher than that in the normal QRS group ( 28. 6%vs. 6. 1%, P=0. 034). QRS complex duration was positively related to LVEDd ( r=0. 4019, P﹤0. 001) and LVESd ( r =0. 3289, P ﹤0. 001 ) . LVEF in male patients was significantly lower than in female patients (40. 0% ± 16. 7% vs. 53. 2% ± 17. 6%, P﹤0. 001). On the contrary, LVEDd [(59. 4 ± 9. 4) mmvs. (50.3±10.6)mm,P﹤0.001],LVESd[(46.6±12.5)mmvs. (36.2±12.4)mm,P﹤0.001] were greater in male patients than in female patients. After adjusting for gender , age, cigarette smoking, history of high blood pressure, serum creatinine, low-density lipoprotein cholesterol, LVEF, LVEDd, LVESd, use of angiotensin converting enzyme inhibitors ( ACEI) or angiotensin receptor blockers ( ARB) and aldosterone receptor blockers, multiple logistic regression analysis showed that prolonged QRS complex duration is an independent risk factor of adverse prognosis for the patients with HF during hospitalization (OR=4. 21,95%CI:1. 59-11. 12,P=0. 004), and female gender is a protective factor for them ( OR=0. 304,95%CI:0. 116-0. 793,P=0. 015). Conc1usions The incidences of left heart failure deterioration, fatal arrhythmias and cardiac death in the chronic left heart failure patients with prolonged QRS duration were higher than in those with normal duration. Female gender is a protective factor for chronic left heart failure.
