Objective To investigate the relationship between galectin-3 and tumour metastasis, and the future prospect of galectin-3 in clinic.Methods Related articles were reviewed. Results Galectin-3, a member of the ?-galactoside-binding proteins, is expressed widely in epithelial and immune cells, and interacts with intracellular glycoproteins, cell surface molecules and extracellular matrix proteins. Galectin-3 is involved in various biological phenomena including cell growth, adhesion, differentiation, angiogenesis and apoptosis, and is associated with invasion and metastasis of tumour. Conclusion Because of the correlation between galectin-3 and tumour invasion and metastasis, galectin-3 may act as the diagnostic marker for tumour metastasis and one of the target proteins for cancer treatment.

Objective To investigate the effect of STAT3 knockdown on the sensitivity of breast cancer cells with drug-resistant to adriamycin (MCF-7/ADR). Methods Levels of STAT3 and p-STAT3 in MCF-7/ADR and MCF-7 cells were detected by Western Blot. The MCF-7/ADR cells were infected with lentivirus expressing STAT3-shRNA and the negative control vectors in the STAT3-RNAi group and NC group, respectively, wihle the cells in the blank group received no treatment. The transfection efficiency was observed with fluorescence microscope, the mRNA level of STAT3, protein levels of STAT3 and p-STAT3 were detected by qRT-PCR and Western Blot, respectively. MCF-7/ADR cells were treated with different concentrations of adriamycin for 48 hours, cell proliferation was detected by MTT assay and cell apoptosis was detected by flow cytometry. Results Levels of STAT3 and p-STAT3 in MCF-7/ADR cells were significantly higher than those in the MCF-7 cells (P < 0.05). The levels of STAT3 mRNA, STAT3 and p-STAT3 in the STAT3-RNAi group were significantly lower than those in the Con group and the NC group (P<0.05, respectively). The Adriamycin IC50 in the Con group, NC group and STAT3-RNAi group was (56.1 ± 3.00)ug/mL,(54.9 ± 11.9)ug/mL and (7.6 ± 0.2)ug/mL, respectively. The flow cytometry results showed that the cell apoptosis in the Con group, the NC group and the STAT3-RNAi group was (10.5+0.7)%, (11.7+0.7)%and (34+3.1)%, respectively. Conclusion LV-shRNA-STAT3 can significantly inhibit STAT3 expression and enhance the sensitivity of breast cancer cells to adriamycin, and the underlying mechanism may be related to cell apoptosis.

Objective To explore the risk factors of newly emerging advanced schistosomiasis patients in endemic areas.Methods The study areas were selected in two counties of Dongting Lake regions and a 1 :2 match case-control study was designed.Sixty schistosomiasis patients,who newly evolved into advanced schistosomiasis from 2006 to 2007,were selected into the case group,and 120 cases with chronic schistosomiasis into the control group.Questionnaires including potential risk factors of advanced schistosomiasis were designed and the information was collected based on face to face interviews.SPSS 12.0 was used to analyze the simple factors and multi ones (logistic regression) attributable to the development of advanced schistosomiasis.Results The history of hepatitis B (OR = 10.729),models of water contact (OR = 3.919) ,yearly exposure days to the infested water (OR = 5.457) and times of chemotherapy in the nearly 10 years(OR = 1.578) were the risk factors of development of advanced schistosomiasis.The times of examinations with positive schistosome eggs were protective factors.No association was found between yearly income,education degree,times of checking for schistosomiasis,times of examination with sera positive results and the emergence of advanced schistosomiasis.Conclusion The high frequency of exposure to the infested water,repeated infections,incomplete diagnosis and treatment are the risk factors of advanced schistosomiasis.The concurrent infection with hepatitis B is associated with the acceleration of development of advanced schistosomiasis.

Objective To evaluate the efficacy and safety of cardiac shock wave therapy(CSWT) in coronary heart disease in elderly patients.Methods Eleven patients with refractory angina pectoris were enrolled.The ischemic area was determined by the 99mTechnetium-MIBI single-photon emission computed tomography (SPECT) and coronary angiography,and treated with CSWT.The CSWT were performed during treatment of 3 months,with 9 times totally.The clinical evaluations included the clinical symptoms,Canadian Cardiovascular Society (CCS) class scores,New York Heart Association class (NYHA),Seattle angina questionnaire (SAQ),6-min walking distance and the use of dosage of nitroglycerin,left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF).The amelioration of ischemic myocardial was analyzed by SPECT.The safety of CSWT was evaluated by changes in clinical symptoms,ECG monitoring,blood pressure and oxygen saturation,blood levels of creatine kinase,creatine kinase myocardial band isoenzymes (CK-MB),troponin T (TnT),alanine transfer enzyme (ALT),creatinine (CR),brain natriuretic peptide and high sensitive C reactive protein (hs CRP).Results The CCS class scores,NYHA,6-min walking distance and the dosage of nitroglycerin were significantly improved at 4 and 12 months after treatment as compared with pretreatment.The steady state of angina pectoris and the frequency score in SAQ were significantly improved.The 21 cardio-vessel segments were treated,and the improvement rate of resting myocardial perfusion was 46.2％ (6/13),the effective rate was 38.5％ (5/13),and the obvious effective rate was 7.8％ (1/13) after treatment.The improvement rate of loaded myocardial perfusion was 57.1％ (12/21),the effective rate was 47.6％ (10/21),and the obvious effective rate after treatment was 9.5％ (2/21).There were no significant changes in levels of CK,CK-MB,TNT,ALT,Cr,BNP and hs CRP,heart rate,systolic blood pressure,diastolic blood pressure and oxygen saturation after treatment as compared with pretreatment.Conclusions The CSWT is a safe and effective treatment for coronary heart disease in the elderly,and the curative effect could maintain at least one year.

0.05). CONCLUSION: Serum Cys C is significantly increased in ARF and correlated well with the severity of ARF. Serum Cys C can be one of the detectable markers of ARF, but it is independent of the mortality and does not predict the prognosis of these patients.

OBJECTIVE:To establish the detection method for pyrogen-related factor interleukin 1β(IL-1β)through optimiz-ing detection condition,and to conduct preliminary methodology study. METHODS:The in vitro fresh human whole blood detec-tion method was used. The bacterial endotoxin standard solution(5,2,0.8,0.32 EU/ml)were added into diluted blood;using di-luted RPMI 1640 as blank control,the content of IL-1β in blood sample was determined by ELISA after incubation. The relation-ship of the addition of different attenuants(RPMI 1640 culture,sterilized normal saline)and fetal bovine serum,final dilution vol-ume fraction(40%,20%,10%and 8.3%)and storage duration(2,5,6,8,26 h)with the contents of endotoxin IL-1βwere in-vestigated,and related coefficient and detection limits were calculated. Different dilution times of Qingkailing injection and Ginaton injection samples and interference solutions were added into diluted blood to detect their recovery. RESULTS:The results indicated that RPMI 1640 media and 40% diluted blood was more sensitive(detection limit was 0.128 EU/ml,r=0.993);while the addition of fetal bovine serum didn’t influence the results. The detection limits of blood sample storied at 4 ℃ for 26 h were 0.128 EU/ml (r>0.990). When Qingkailing injection and Ginaton injection were diluted 10,32 and more times,the detection method was not interfered and the recovery ranged 68%-118%. CONCLUSIONS:Established in vitro fresh human whole blood detection method can be used for the detection of pyrogen,and provides trial evidence for the pyrogen detection of TCM injection.

One hundred and six men aged >60 years were assigned to Group A (60 to 69 years old, n=33), Group B (70 to 79 years old, n=38) or Group C ( >80 years old, n =35), respectively. Serum testosterone, broadband ultrasound attenuation (BUA), speed of sound (SOS) , and stiffness (STI) were determined. Our results showed that as age increased, serum testosterone, BUA, SOS and STI decreased; serum testosterone was positively correlated with BUA ( r=0.62, P<0.05 ) and SOS ( r=0.54, P<0.05 ). We thus suggest that serum testosterone in elderly men might be closely related with bone mineral density.
