1.Progress of research on predicting breast cancer prognosis based on multi-gene expression levels
Chinese Journal of Clinical Oncology 2013;(13):807-810,814
Breast cancer is one of the most common cancers in women. Current clinical prognostic indicators and practice guide-lines show that almost 70% of node-negative and 30% of lymph node-positive breast cancer patients can survive 5-10 years without dis-tant metastasis after surgery. Patients also unnecessarily suffer the side effects of chemotherapy. Assays on multi-gene expression levels as prognosis prediction indicators have been successfully used to predict the prognosis of breast cancer patients because of the abnor-mal expression levels of a series of metastasis-related genes in cancer cells with high metastatic potential. In this review, we highlight the progress of research on predicting breast cancer prognosis based on multi-gene expression levels detected by microarray and qRT-PCR methods.

It is hypothesized that H 2S is the third endogenous signaling gasotransmitter, after NO and CO. Endogenous H 2S may regulate some aspects of synaptic activity via cAMP mediated pathways and function as a neuromodulator or transmitter. H 2S is an endogenous vasorelaxant factor that activates K ATP channels and hyperpolarizes membrane potential of vascular SMCs. By directly acting on vascular SMCs, H 2S may reduce the extracellular calcium entry and relax vascular tissues.

Objective: To understand current situation and existing problems in financial security of the center for disease control and prevention system in Jiangxi, to provide scientific references for advancing continuous, fast and healthy development of the system. Methods: combining three methods of questionnaire, group discussions and field surveys to investigate the situation of financial income from 112 centers of disease control and prevention in Jiangxi. Results: The government finance investment increased by year, but the funds of daily work and personnel is insufficient, public and regular business funds of some institution still depend on paid service income. Conclusion: It needs to further enhance financial structure adjustment and disease control investment, increase disease control input, change government appropriation method for disease prevention and control institutions, change the government ’ s funding mode to “purchase system” , reasonably pricing public product, the government on behalf of the people buying services according to quality and quantity from the disease prevention and control institutions.

Aim To study the adaptive protection of H_2O_2 preconditioning against dopamine-induced damage in PC12 cells.Methods The apoptosis of PC12 cells was observed by electron microscope, PI stain flow cytometry (FCM) and Hoechst stain. The mitochondrial energy redox state was measured by MTT assay. The mitochondrial membrane potential(△?m) was investigated by the fluorescent probe of rhodamine 123.Results PC12 cells exposed to 50 ?mol?L -1 DA showed chromatin condensation and nucleus fragmentation observed by electron microscope. Exposure to DA (50 ?mol?L -1) for 24 h, the apoptosis of PC12 cells preconditioned by 10 ?mol?L -1 H_2O_2 for 90 min as measured by Hoechst stain was significantly decreased,compared with no-preconditioned cells. Exposure to 50,100,and 200 ?mol?L -1 H_2O_2 for 24 h, the proportion of apoptosis of PC12 cells was decreased from (20.9?1.8)%, (40.5?6.4)% and (88.1?3.9)% to (4.9?2.9)%, (12.0?1.4)%, (61.5?3.4)% after H_2O_2 preconditioning, respectively. By exposuring PC12 cells to 20,40,and 80 ?mol?L -1 DA for 24 h, the rates of MTT metabolism were reduced and the effect was prevented by H_2O_2 preconditioning. After 50 ?mol?L -1 DA exposure for 24 h,the mean fluorescence intensity of rhodamine 123 in no-preconditioned PC12 cells was decreased from (46.87?0.33) to (4.39?2.93),and that of preconditioned PC12 cells was decreased from (46.87?0.33) to (10.50?0.28). Conclusion H_2O_2 preconditioning possesses adaptive protection against dopamine-induced damage in PC12 cells.

AIM To investigate the poteintation of adriamycin induced apoptosis by neferine in resistant human breast cancer cell line MCF 7/Adr. METHODS Apoptosis was detected by PI stain flow cytometry and Tunel assay. The intracellular adriamycin (ADR) accumulation was assayed by HPLC and the expression of P gp was determined by flow cytometry. RESULTS (1)MCF 7/Adr cells resisted the apoptosis induced by ADR while Nef augmented ADR medidated apoptosis; (2) Nef (10 ?mol?L -1 ) increased the accumulation of ADR up to 2 88 fold in MCF 7/Adr cells but not in sensitive cells MCF 7/S; (3) Nef(10 ?mol?L -1 ) reduced the expression of P gp in MCF 7/Adr cells. CONCLUSIONS Nef can overcome apoptosis resistance in MCF 7/Adr cells and its mechanisms are involved in the augment of ADR accumulation and the down-modulation of P gp expression in MCF 7/Adr cells.

Objective To identity the risk factors for supine hypotension syndrome (SHS) after spinal anesthesia in parturients.Methods A total of 204 parturients,scheduled for elective cesarean section,were divided into either control group or SHS group depending on whether or not SHS (systolic blood pressure [SBP] in the upper extremity decreased by > 30 mmHg or decreased to < 80 mmHg) developed after spinal anesthesia.The baseline patient characteristics such as age,body height and weight,gestational weeks and biparietal diameter were recorded.Supine stress test (SST) was performed.Heart rate,blood pressure in upper and lower extremities,perfusion index,pleth variability index and intravesical pressure were recorded when patients were in supine position and in left lateral position before spinal anesthesia.The risk factors of which P values were less than 0.05 would enter the multi-factor logistic regression analysis to stratify the risk factors for SHS.Results Among the 204 patients,99 cases developed SHS after spinal anesthesia,and the incidence was 48.5%.Logistic regression analysis showed that maternal body weight,biparietal diameter,the difference in SBP between upper and lower extremities in supine position,the difference in SBP in upper extremities caused by changing position and positive SST were risk factors for SHS after spinal anesthesia (P<0.05 or 0.01).Conclusion Maternal body weight,biparietal diameter,the difference in SBP between the upper and lower extremities in supine position,the difference in SBP in upper extremities caused by changing position and positive SST are risk factors for SHS after spinal anesthesia in parturients.
